In a preferred embodiment, the FPC is " returning " character form structure of a side opening.

In a preferred embodiment, the FPC is provided with several through-holes, institute far from one end of the pcb board Stating through-hole can be used for the FPC and extraneous installation fixation.

In a preferred embodiment, EVA foam is also filled between the pcb board and the battery core.

In a preferred embodiment, the EVA foam with a thickness of 1 to 3mm.

In a preferred embodiment, the two sides of the battery core are also pasted with PI glue band.

It in a preferred embodiment, further include having polyurethane foam, the polyurethane foam wraps the electricity Front, reverse side, left side, right side and the bottom surface of core.

In a preferred embodiment, the polyurethane foam with a thickness of 0.1 to 0.3mm.

A kind of battery includes above-mentioned battery packing structure.

The beneficial effects of the utility model are:

Pcb board is placed in the groove at the top of battery core by the utility model, is conducive to protect pcb board, is prevented pcb board in battery Collision is generated when falling, while using FPC as the output end of battery, FPC is designed to that battery thus can be prevented with elastic construction FPC generates tearing when generating relative displacement with the external world, guarantees the performance of product.

Detailed description of the invention

The utility model is described further with reference to the accompanying drawings and examples.

Fig. 1 is the perspective view of the explosion of the battery packing structure of the utility model one embodiment；

Fig. 2 is the oblique view of one embodiment of the utility model battery core.

Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that not conflicting In the case where, the features in the embodiments and the embodiments of the present application can be combined with each other.

It should be noted that unless otherwise specified, when a certain feature referred to as " fixation ", " connection " are in another feature, It can directly fix, be connected to another feature, and can also fix, be connected to another feature indirectly.In addition, this The descriptions such as upper and lower, left and right used in utility model are only the phase relative to each component part of the utility model in attached drawing For mutual positional relationship.
