When those appliances are purchased, batteries may be included in the working appliances or else buyers may have to buy batteries separately.
The primary cells used in the battery-operated toys or working appliances such as the electronic workbooks have high natural discharge rates such that the life spans are short. Accordingly, the batteries cannot be used efficiently and therefore should be replaced frequently by new ones, which increase expenses. In addition, mass production of the batteries causes waste of natural resources and environmental pollution.
Though secondary cells such as a nickel-cadmium cell and a nickel- hydrogen cell are sometimes used in the battery-operated toys or working appliances such as the electronic workbooks described above, the purchasing prices of the cells are relatively higher compared to the prices of working appliances such that it places a heavy burden to the purchaser. In addition, the secondary cells need a separate charger, it takes much time to charge the cells, and repetitive charging and discharging makes the performance of the cells degraded. Accordingly, secondary cells are not generally used for battery-operated toys or working appliances such as electronic workbooks.

Best mode for carrying out the invention
FIGS. 1 through 3 are a perspective view of an example of a working appliance according to the present invention, a perspective view of a battery mounting apparatus for a working appliance according to the present invention, and a plane view of a battery mounting apparatus for a working appliance according to the present invention, respectively.
Referring to FIG. 1 , in the present embodiment, a small toy car is employed as a working appliance 100, and on the bottom part of the small toy car, a battery mounting unit 110, on which batteries for mobile communications devices of a roughly rectangular shape can be mounted, and a lid unit 102 which can cover the top side are disposed. The lid unit 102 has a shape similar to a structure used for a battery mounting apparatus for an ordinary electric toy car. This lid unit 102 is not necessarily needed but it is desirable that the lid unit 102 is disposed so that batteries for mobile communications can be solidly fixed on the battery mounting unit 110. This lid unit 102 may be an element of a battery fixing unit which will be explained later.
The battery mounting unit 110 may be formed integrated into the body of the working appliance 100, or may be formed by installing a battery mounting apparatus 104 constructed by using a separate case 104a, as shown in FIGS. 2 and 3. The battery mounting unit 110 can be applied to a variety of working appliances without being limited by the type, size and shape of working appliance.
In the working appliance 100 and the battery mounting apparatus for a working appliance 104 according to the present invention, a battery recipient unit 111 which solidly accommodates batteries of a mobile communications device, for example, a mobile telephone, terminals 130 which are installed on one side of the battery recipient unit 111 , and a battery fixing unit 150, which fixes batteries that are solidly placed on the battery recipient unit 111 , are disposed.
The battery recipient unit 111 is to solidly accommodate batteries for mobile communications devices, which are placed on one side of a working appliance and with a roughly rectangular plate shape, has a terminal unit for recharging and a terminal unit for supplying power. It is desirable that the battery recipient unit 111 is made to be a recess of a roughly rectangular shape for a relatively bigger battery so that batteries with varying sizes can be mounted.
On one side of the battery recipient unit 111 , terminals 130 are disposed protruding upward with intervals. These terminals 130 has a semicircle ring shape and are supported by their own elasticity or by a spring installed inside a slider 131 so that these terminals 130 are always protruding upward. For the installation structure of these terminals 130, a known conventional structure installed in a mobile communications device may be employed as is.
These terminals 130 with being mounted on the working appliance are connected to an internal substrate or motor such that power of the batteries is provided to the substrate or motor side. These terminals 130 are disposed on a slider 131 which is installed such that the slider 131 can move from side to side along a guide groove 132 formed in the width direction and a rail 133 formed on the side surface of the guide groove 132. This is to adjust the locations of the terminals 130 so that the terminals can contact with terminal units of a battery irrespective of the specification of the mounted battery. That is, in the present embodiment, terminals installed on the slider 131 can be moved such that even though the location of a terminal unit for supplying power of a battery may vary according to the type of the battery when the battery for mobile communications devices is mounted on the battery recipient unit 111 , the terminals can contact with terminal units for supplying power of each battery on respective different locations. Surely, the terminals 130 are connected to a substrate or motor of the working appliance through a flexible printed circuit board (FPCB) or a wire with a connector. The battery fixing unit 50 is to enable a battery of a roughly rectangular plate shape to be solidly placed and fixed on the battery recipient unit 111. This battery fixing unit 150 needs only to solidly fix a battery in a desired location such that the battery fixing unit 150 can be modified in a variety of shapes. This battery fixing unit 150 comprises a first elastic pressure apparatus 151 which in order to prevent a mounted battery from moving from side to side, is installed on the three side walls, except the wall on which the terminals 130 are disposed, and a second elastic pressure apparatus which is installed on one side of the battery recipient unit 111 and pressures the back of the battery so that the battery can be fixed on the battery mounting unit 110.
The first elastic pressure apparatus 151 is elastically supported by springs 152 inserted on the three side walls of the battery recipient unit 111 so that the first elastic pressure apparatus 151 can be expanded or contracted with respect to the size of a mounted battery. On the surface of the first elastic pressure apparatus 151 , material such as rubber 153 which has elasticity is attached so that the battery can be more solidly fixed by the rubber 153.
In addition, a fixing bar 157 is coupled on each middle point of the two legs of the second elastic pressure apparatus 156. Each end of the two legs is folded toward outside and is elastically supported by a spring inserted on the bottom of each of right-hand side and left-hand side walls of the battery recipient unit 111. By the elasticity of the spring coupled with each end of the two legs of the second elastic pressure apparatus 156, the back of the mounted battery is pressured so that the battery is solidly fixed. Here, if only the second elastic pressure apparatus 156 can pressure and fix the outer surface of a mounted battery, the apparatus 156 can be modified with varying shapes and structures.
At present, batteries for mobile communications devices that are sold in the market have electrode terminals with varying locations and intervals with respect to manufacturers and platforms. Accordingly, when a battery is mounted, the slider 131 moves from side to side for adjustment so that the terminal units of the battery can contact accurately with the terminals 130.
In the present embodiment, a structure in which the slider 131 moves from side to side guided by the guide groove 132 and rail 13 is employed. However, a structure, in which the slider 131 is coupled with a screw unit that can rotate and moves from side to side gearing with the screw unit, may also be employed.
Besides, any other structure in which the slider 131 moves from side to side can be employed.
In the conventional battery-operated toys such as toy cars, toy helicopters and toy robots, two 1.5V batteries (1.5V x 2 = 3V) are generally used. Accordingly, even when the batteries for mobile communications devices described above are used as batteries for the working appliances, no problems will take place. In addition, when 3.7V lithium secondary batteries are used also in a working appliance using four 1.5V batteries, the working appliance can operate without any problem. Since each of the batteries for mobile communications devices has a high voltage (4.2V initial voltage) and a high capacity current (about 1000mA) in a single cell, it can operate actually a working appliance using six 1.5V batteries, that is, using about 9V. Usually, a battery-operated toy uses this high voltage in order to rotate a motor at a high speed. If the fact that this is a toy is considered, a motor driving circuit can be redesigned to use a middle level voltage (about 4V), instead of a compulsory high voltage, a battery-operated toy that can show its full performance can be manufactured with considering the high current.
FIG. 4 is a perspective view of another example of a working appliance according to the present invention.
FIG. 4 is a toy boat employed as a working appliance of the present invention 100a. A battery mounting unit 110, on which batteries for mobile communications devices of a roughly rectangular shape can be mounted, is formed on one side of the top surface of the working appliance 100a. This battery mounting unit 110 can be constructed by forming a battery recipient unit 111 of a roughly rectangular recess shape on one side of the top surface of the working appliance 100a and installing anode terminals 130a and cathode terminals 130b along an edge of the battery recipient unit 111 , in which the number of pairs of the anode terminals 130a and cathode terminals 130b is at least three or more, and each of the terminals 130a and 130b is 5mm or longer than that of the conventional terminals (about 4mm) in the length direction, and preferably, the length is 6mm ~ 20mm.
The structure for a battery fixing unit 150 may comprise a second coupling unit 161 and a moving unit 165 having a fourth coupling unit 164. Here, the second coupling unit 161 is disposed on an edge of the battery recipient unit 111 as in the conventional mobile communications devices, and enables a first coupling unit 51 , which is formed on one side of a battery for mobile communications devices 50 of a roughly rectangular plate shape, to be coupled with the second coupling unit 161. The moving unit 165 is disposed on the side opposite to the second coupling unit 161 and is elastically supported so that the moving unit 165 is movable. The fourth coupling unit 164 on the moving unit 165 is coupled with a third coupling unit 53 formed on the other side of the battery 50 so that the battery for mobile communications devices 50 of a roughly rectangular plate shape is not separated from the battery recipient unit 111. While the battery for mobile communications devices 50 is mounted and fixed on the battery mounting unit 110 having the structure described above, the anode terminal unit 55 of the battery for mobile communications devices 50 contacts with some of the anode terminals 130a and the cathode terminal unit 55 of the battery for mobile communications devices 50 contacts with some of the cathode terminals 130b such that power needed by the working appliance 100a is supplied.
FIG. 5 is a perspective view of another example of a battery mounting apparatus.
The battery mounting apparatus 104 of FIG. 5 has a battery mounting unit 110 formed on a case 104a which can be mounted on a battery-operated toy or an electronic workbook. The battery mounting unit 100 is formed by arranging many anode terminals 130a and cathode terminals 130b so that the battery mounting unit 100 can be applied to a variety of working appliances without being limited by the type, size, and shape of working appliance. That is, the battery mounting unit 100 is constructed so that even when the locations of terminals on a battery are a little different, terminals 130a and 130b can contact with the terminals of the battery. In other words, the arrangement of terminals 130 shown in FIG. 5 can be applied, without change, to a case where a battery mounting unit is formed as an integral part of a battery-operated toy or an electronic workbook. The remaining parts, a battery recipient unit 111 and a battery fixing unit 150 for fixing a battery retained in the battery recipient unit 111 , are the same as explained in the previous embodiment. FIG. 6 is a perspective view of a modified example of the battery mounting apparatus of FIG. 5.
As shown in FIG. 6, without dividing each of an anode terminal 130a and a cathode terminal 130b into a plurality of terminals, the terminal 130 can be formed by using a wide conductive member. The remaining parts, a battery recipient unit 111 , and a battery fixing unit 150 formed with a first elastic pressure apparatus 151 and a second elastic pressure apparatus 156, are the same as explained in the previous embodiment.
FIG. 7 is a perspective view of a still another example of a battery mounting apparatus according to the present invention. The battery mounting apparatus 104 of FIG. 7 has a battery mounting unit 110 formed on a case 104a which can be mounted on a battery-operated toy or an electronic workbook. The battery mounting apparatus 104 has an additional primary cell mounting unit 120, which comprises a recess 121 into which a cylinder-shaped primary battery can be mounted, and terminals 122 which are installed on both sides of the recess facing each other terminals. The terminals 122 are connected to an internal substrate or motor of a working appliance such as a battery-operated toy, when installed in the appliance. The primary cell mounting unit 120 of FIG. 7 can be applied, without change, to a 0872
case where a battery mounting unit is formed as an integral part of a battery- operated toy or an electronic workbook. The remaining parts, a battery recipient unit 111 and a battery fixing unit 150 for fixing a battery retained in the battery recipient unit 111 , are the same as explained in the previous embodiment.
When the battery mounting apparatus 104 shown in FIG. 7 is used, or when the battery mounting unit and the primary cell mounting unit are formed as an integral part of a battery-operated toy or an electronic workbook, conventional cylinder-shaped primary cells and batteries for mobile communications devices which are secondary cells of a rectangular plate shape can be used together.
FIGS. 8 and 9 are respective diagrams of second elastic pressure apparatuses.
As shown in FIG. 8, a fixing bar 156 is coupled on each middle point of the two legs of the second elastic pressure apparatus 156. Each end of the two legs 158 is folded toward outside and is elastically supported by a spring inserted on the bottom of each of right-hand side and left-hand side walls of the battery recipient unit 111. By the elasticity of the spring coupled with each end of the two legs 158, the back of the mounted battery is pressured so that the battery is solidly fixed. On the surface of the second elastic pressure apparatus 156 facing the battery, rubber is installed so that the battery can be elastically pressured. When necessary, a rubber board 156a covering a wide area as shown in FIG. 9 can be attached so that the power fixing the battery can increase. FIG. 10 is a diagram of another example of a second elastic pressure apparatus.
As shown in FIG. 10, if the second elastic pressure apparatus 156 is installed in the vicinity of the battery recipient unit, by forming leg units 158 of the second elastic pressure apparatus 156 to have different lengths, elasticity to pressure a battery mounted on the battery recipient unit can be generated without an additional spring.
FIG. 11 is a perspective view of another modified example of the battery mounting apparatus of FIG. 5.
As shown in FIG. 11 , when necessary, terminals 130 can be disposed with extended lengths so that the terminals can contact with terminal units of a battery for mobile communications devices irrespective of the locations of the terminal units of the battery in the length direction. While the length of a terminal in an ordinary mobile communications device is about 4mm, the length in the present invention is desirably 5mm~15mm and can be a longer one. The remaining parts are the same as explained referring to FIG. 5.
FIG. 12 is a perspective view of still another modified example of the battery mounting apparatus of FIG. 5. As shown in FIG. 12, when necessary, grooves 130 are formed on a side wall on which terminals 130 are disposed so that the grooves 130 can be coupled with protrusions at the bottom of a battery in order to more solidly fix the battery. The remaining parts are the same as explained referring to FIG. 5.
The contents applied to the case of each battery mounting apparatus described above can be applied to the body of a working appliance such as a battery-operated toy, an electronic workbook, and a camera, without change as explained above. Industrial Applicability
