Description

Technical Field

[0001] The utility model relates to an extended heat dissipation structure of a battery protection plate FPC. Background Art

[0002] With the needs of practical applications, in order to increase the endurance of mobile terminal equipment, the charging power of the battery of the mobile terminal is made larger and larger. In the design of the battery protection board in the past, the battery protection board adopts a multi-way FPC lead-out structure, or the battery FPC adopts a thicker and wider structure to achieve heat dissipation. However, the above two solutions occupy the use area of ​​the battery and the whole machine, thereby increasing the size of the whole machine or reducing the capacity of the battery, while increasing high costs. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a battery protection board FPC extended heat dissipation structure with a simple structure and low cost, which does not occupy additional use area of ​​the battery or the whole machine.

[0004] The utility model comprises a battery body and a battery protection board FPC connected to the end of the battery body, wherein the external lead end of the battery protection board FPC is folded and placed on one side of the battery protection board FPC, and the external lead end is laterally extended to be provided with an extended heat sink, and the extended heat sink is adapted to be arranged on one side of the battery protection board FPC and adapted to be arranged on the end of the battery body.

[0005] The length of the extended heat sink is matched with the width of the bottom side of the battery body.

[0006] The length of the extended heat sink is smaller than the width of the bottom side of the battery body.

[0007] The width of the extended heat sink corresponds to the width of the battery protection board FPC.

[0008] The exterior of the extended heat sink is adapted to be wrapped with an insulating coating layer.

[0009] Beneficial effect: In the utility model, an extended heat sink is extended on one side of the original folded external lead end of the battery protection board FPC, avoiding the previous battery protection board using a multi-way FPC lead-out structure or the battery FPC using a thicker and wider structure to achieve a heat dissipation solution, thereby avoiding increasing the overall size of the machine or reducing the capacity of the battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the overall front structure of the utility model;

[0011] Figure 2 It is a schematic diagram of the overall top view structure of the utility model. DETAILED DESCRIPTION

[0012] like Figure 1 , Figure 2 As shown, the utility model includes a battery body 1 and a battery protection board FPC2 connected to the end of the battery body 1, the external lead end 21 of the battery protection board FPC2 is folded and placed on one side of the battery protection board FPC2, and the external lead end 21 is laterally extended to be provided with an extended heat sink 3, and the extended heat sink 3 is suitable for being configured on one side of the battery protection board FPC2 and suitable for being configured on the end of the battery body 1.

[0013] The length of the extended heat sink 3 is adapted to the width of the bottom side of the battery body 1 and is smaller than the width of the bottom side of the battery body 1. The width of the extended heat sink 3 is adapted to correspond to the width of the battery protection board FPC2.

[0014] The exterior of the extended heat sink 3 and the exterior of the battery protection board FPC2 are both adapted to be wrapped with an insulating coating layer.

[0015] Since the external lead end 21 is originally folded and arranged on one side of the battery protection board FPC2, in this specific embodiment, the extended heat sink 3 extended on one side of the external lead end 21 is also arranged on one side of the battery protection board FPC2, which plays the role of extended heat dissipation without occupying additional usable area.

[0016] The utility model is suitable for the field of heat dissipation of battery protection board FPC.
