Embodiment 1

[0045] The implementation principle of Embodiment 1 is: first make the heat dissipation bag 21 contact with the surface of the rechargeable battery 10 to perform heat exchange, thereby reducing the temperature of the rechargeable battery 10 during charging, so as to maintain the performance of the battery. 21 After the temperature rises, the driving mechanism 23 can be used to remove the heat dissipation bag 21 from the rechargeable battery 10, so that there is a ventilation gap between the two, and the air in the middle is used to cool down the heat dissipation bag 21 and the rechargeable battery 10, so as to prepare The heat dissipation bag 21 is attached again for heat dissipation next time, and the heat dissipation is continuous and the heat dissipation effect is stable.

Embodiment 2

[0046] Embodiment 2 is different from Embodiment 1 in that, as Figure 4 , Figure 5 As shown, the charger main body 1 includes a housing 11 , a cover 13 , a first charging circuit board 111 inside the housing 11 , and a second charging circuit board 131 inside the cover 13 . The housing 11 is provided with a battery cavity 20 with an opening, and the battery cavity 20 is used for placing the rechargeable battery 10 ;

[0047] like Figure 5 As shown, the first charging circuit board 111 is provided with a first conductive sheet 112 corresponding to the positive pole of the rechargeable battery 10. The first conductive sheet 112 is located at the bottom of the battery cavity 20, and the bottom of the battery cavity 20 is also fixed with a Corresponding to the first limiting collar 113 of the positive terminal of the rechargeable battery 10 . The second charging circuit board 131 is provided with a second conductive sheet 132 for cooperating with the negative pole of the rec...

Abstract

The invention relates to a battery charger which comprises a charger body and a heat dissipation device located in the charger body, the heat dissipation device comprises a heat dissipation bag and a driving mechanism, and the driving mechanism is used for driving the heat dissipation bag to move close to or away from a rechargeable battery. Through the arrangement of the heat dissipation bag and the driving mechanism, the heat dissipation bag is in contact with the surface of the rechargeable battery for heat exchange, so that the temperature of the rechargeable battery in the charging process is reduced, and the use performance of the battery is maintained; moreover, the distance between the heat dissipation bag and the rechargeable battery is controlled through the driving mechanism, so that different heat dissipation modes are formed to adapt to different charging working conditions.

Description

technical field [0001] The present application relates to the field of charging devices, in particular to a battery charger. Background technique [0002] The battery charger is used to charge the rechargeable battery and make it reusable. It is a good choice to avoid environmental pollution caused by the battery after it is discarded. [0003] Common battery chargers currently on the market include a battery clip with a charging circuit and a plastic housing, wherein the battery clip is used to clamp and charge the rechargeable battery. [0004] With regard to the related technologies mentioned above, the inventor believes that the battery will release heat during charging and discharging, which will increase the temperature of the battery itself. Nowadays, in order to save time and improve work efficiency, the charging requirements for batteries are generally developing in the direction of fast charging. The charging time requirements of batteries are getting shorter and ...
