A purpose more of the present utility model is, proposes a kind of Thin battery structure, is metal material by this lamellar body, can effectively utilize the characteristic of this metal material, makes the function that reaches quick heat radiating, to increase whole practicality.

Of the present utility model time a purpose is, a kind of Thin battery structure is proposed, this lamellar body is the heat insulating lamella of plastics, under soft, the elasticity and variable condition by plastics itself, make the junction can form the strength of buffering, avoid box body to cause structure badly damaged, to increase durability because of internal cell expands.

For reaching above-mentioned purpose, the utility model provides a kind of Thin battery structure, comprising: a framework is a hollow form, and the periphery of this framework is provided with combined hole; And at least one lamellar body, the periphery of this lamellar body is extended with the hook part, and this hook part is the L type, and the combined hole of the hook part of this lamellar body and framework periphery mutually combines, and lamellar body and framework are combined closely.

The utlity model has following useful technique effect:

1, the combined hole by framework cooperates with the hook part of lamellar body, can make framework engage mutually with lamellar body, and fixedly lamellar body is incorporated into position on the framework thus, utilizes lamellar body to press from both sides and establishes this framework to form a box body, can increase the practicality and the convenience of integral body.

2, the L type hook part by lamellar body engages with the combined hole of framework, can make lamellar body still can be incorporated into framework after being heated and keeps box body structure, avoids box body structure badly damaged.

3, be metal material by this lamellar body, can effectively utilize the characteristic of this metal material, make the function that reaches quick heat radiating, can increase whole practicality.

4, because this lamellar body is the heat insulating lamella of plastics, under soft, the elasticity and variable condition by plastics itself, make the junction can form the strength that cushions, avoid box body because of the internal cell expansion causes structure badly damaged, can increase durability.

Other characteristics of the present utility model and specific embodiment can further be understood in the detailed description of following conjunction with figs..

Embodiment

Please refer to shown in Fig. 1～3, the utility model is a kind of Thin battery structure, includes:

One framework 10 is a hollow form, and the perimeter side walls 11 of this framework 10 is provided with combined hole 12, and a side of this framework 10 can further be provided with conduit 13.

At least one lamellar body 20 is sheet metal or plastic insulation thin slice, and this lamellar body 20 is incorporated into this framework 10, and the periphery extension of this lamellar body 20 is provided with hook part 21, and this hook part 21 is the L type, and this hook part 21 engages mutually with the combined hole 12 of framework 10 perimeter side walls 11.

Please join Fig. 1～3, characteristics of the present utility model are to cooperate with the hook part 21 of lamellar body 20 by the combined hole 12 of framework 10, can make framework 10 engage mutually with lamellar body 20, and fixedly lamellar body 20 is incorporated into position on the framework 10 thus, utilize lamellar body 20 folders to establish this framework 10, to form a box body; Moreover, after the L type hook part 21 of this lamellar body 20 snaps in the combined hole 12 of this framework 10, this hook part 21 can't be thrown off in combined hole 12 again, and meaning i.e. this lamellar body 20 can't be separated from framework 10 with nondestructive method, makes this lamellar body 20 can utilize this L type hook part 21 to be incorporated into securely on the framework 10.

Please join shown in Figure 4 in addition, battery pack 30 places this framework 10 during use, this framework 10 is provided with conduit 13 for the printed circuit board (PCB) 31 of putting this battery pack 30, utilize lamellar body 20 that this battery pack 30 is coated in the framework 10 again, can generate heat when using because of battery, this lamellar body 20 is under the situation of thermal stress, utilize the L type hook part 21 of lamellar body 20 closely to engage with the combined hole 12 of framework 10, therefore can make lamellar body 20 after being heated, still can be incorporated into framework 10, and this lamellar body 20 is metal thin slice, can effectively utilize the characteristic of this metal material to reach the function of quick heat radiating, or be the heat insulating lamella of plastics, soft by plastics itself, under elasticity and the variable condition, it is not yielding to make the junction can form the strength that cushions, increase durability, make the utlity model has and cause effects such as box body structure is badly damaged after avoiding battery to be heated, increase its practicality and convenience.Please join Fig. 5, be second embodiment of the present utility model, this framework 10 is provided with combined hole 12 in the circumferential surface 14 of periphery, when making up this box body, the hook part 21 of this lamellar body 20 engages mutually with combined hole 12 on the circumferential surface 14, makes this lamellar body 20 utilize this hook part 21 to be incorporated into framework 10 securely.
