Description

Technical Field

[0001] The present invention relates to the field of charging, and in particular to a battery charging box. Background Art

[0002] The battery charging box has a cover body and a box body. The cover body is connected to the box body in a pivoting direction. There is a groove in the box body for placing the battery. When the user wants to charge the battery, the battery charging box is in an open state, that is, the cover body is not closed on the box body, exposing the groove of the box body, and the battery is placed in the groove of the box body to charge the battery. However, in the traditional battery charging box, the power supply circuit board is arranged in the box body, that is, the battery and the power supply circuit board are arranged at the same position. Therefore, the heat generated by the battery and the power supply circuit board is all in the box body, so that the battery will receive the heat generated by the power supply circuit board, which is likely to reduce the life of the battery. Moreover, the box body of the traditional battery charging box needs to be additionally provided with an air duct and a fan to discharge its heat, resulting in a higher cost of the traditional battery charging box and a greater noise generated by the operation of the fan.

[0003] Therefore, how to develop a battery charging box that overcomes the above disadvantages is an urgent need at present. Summary of the Invention

[0004] The purpose of the present invention is to provide a battery charging box for charging and discharging the battery. The battery charging box includes a box body, a cover body and a connecting member. The box body includes a first housing and a receiving groove. The receiving groove is arranged in the first accommodation space of the first housing and is used for accommodating the battery. The cover body includes a second housing, a first cover plate, a second cover plate and at least one AC / DC conversion module. The first cover plate, the second cover plate and at least one AC / DC conversion module are arranged in the second accommodation space of the second housing. The first cover plate is made of metal and is arranged between the second cover plate and the bottom of the second housing. The second cover plate includes at least one heat dissipation hole. At least one AC / DC conversion module is arranged between the second cover plate and the first cover plate. The first housing of the box body and the second housing of the cover body are pivotally connected to each other through the connecting member.

[0005] To achieve the above object, an embodiment of the present invention is a battery charging box. The AC / DC conversion module of the battery charging box is disposed in the second main accommodation space of the second housing of the cover body, while the battery is disposed in the accommodation groove of the box body of the battery charging box. That is to say, the main heat source of the battery charging box (i.e., the AC / DC conversion module) and the battery are respectively disposed in two separable components of the battery charging box. And since the cover body and the box body are in a separated state when the battery charging box receives AC power, the battery can be prevented from being additionally affected by the heat energy generated by the AC / DC conversion module, thereby reducing the temperature inside the battery charging box and enabling the battery used for charging and discharging with the battery charging box of the present invention to have a longer service life. In addition, the first cover plate of the battery charging box of the present invention is made of a metal material, and the second cover plate is provided with heat dissipation holes, so that the heat energy generated by the adjacent AC / DC conversion module can be conducted to the outside, thereby enhancing the heat dissipation effect of the AC / DC conversion module, increasing the strength of the overall cover body, and enabling the battery charging box not to be additionally provided with a fan, thereby reducing the manufacturing cost of the battery charging box and reducing its noise.

Each partition notch 321 is formed by the side of the partition 32 adjacent to the cover 4 being recessed inward. The first through hole 322 penetrates the partition 32 and is close to one of the two partition notches 321. Hereinafter, the partition notch 321 closer to the first through hole 322 is referred to as the first partition notch 321, and the other partition notch 321 is referred to as the second partition notch 321. The setting portion 323 can be a recess for setting documents or indexes and is located between the first partition notch 321 and the first through hole 322. The output through hole 324 penetrates the partition 32 and is located between the setting portion 323 and the first through hole 322. Each accommodation groove 33 is formed by the upper surface of the partition 32 being recessed in the direction towards the bottom of the first housing 31 and is located in the first main accommodation space 311 of the first housing 31 for accommodating the corresponding battery 2. In this embodiment, the number of accommodation grooves 33 is nine, and the nine accommodation grooves 33 are arranged in three rows, and the number of each row is three. In Figure 2 the battery 2 is disposed in the accommodation groove 33 located in the second column of the first row, and the first through hole 322 of the partition 32 is adjacent to the accommodation groove 33 in the third column of the third row.
