The application aims at providing a low-voltage battery package structure that shockproof effect is good, and long service life.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the above-mentioned not enough of prior art and providing a low voltage battery package structure takes precautions against earthquakes, and it is effectual that takes precautions against earthquakes, has improved the overall stability of battery package, and then the life of extension battery package.

The technical scheme of the utility model is that: a shockproof low-voltage battery pack structure comprises a shell and a battery module, wherein the battery module is arranged in the shell and comprises a frame body and a battery pack, the frame body is a rectangular frame formed by enclosing four side plates, and the battery pack is arranged in the frame body; still include the damping piece, four lateral surfaces of framework all are connected with the casing through the damping piece, and the group battery is formed by rectangular bodily form's battery cell array for the group battery is whole also to be rectangular bodily form, is provided with the baffle between adjacent battery cell, the baffle has insulating and cushioning effect. The partition plate can be made of a silica gel material, and the damping piece can be made of rubber.

Furthermore, all be equipped with a plurality of shock attenuation pieces on every lateral surface of framework, and separately set up between a plurality of shock attenuation pieces.

Further, the damping piece is bonded with the outer side surface of the frame body by using fixed glue or the damping piece is bonded with the inner side surface of the shell body by using fixed glue; the shock-absorbing piece is only fixedly connected with one of the outer side surface of the frame body or the inner side surface of the shell, so that the shock-absorbing piece is convenient to disassemble and assemble.

Furthermore, the shock-absorbing member is rectangular block-shaped, and the specific thickness of the shock-absorbing member is designed according to actual needs. In some specific embodiments, the shock absorbing member may also be a cylinder with two thick ends and a thin middle (for example, an hourglass shape formed by two truncated cones), so that when the shock absorbing member is impacted, the middle part of the shock absorbing member has smaller bearing capacity than the two end parts, and a part of impact force can be consumed through larger left and right deformation of the middle part, so that the shock absorbing performance is improved.

Furthermore, through holes are formed in part of the damping pieces, and the axial direction of each through hole is parallel to the outer side face of the frame body; preferably, the through-hole on the damper has a plurality ofly, and the through-hole has formed honeycomb in the bumper shock absorber after the array, like this when guaranteeing damping performance, also does not influence the flow of air, and the thermal diffusivity is better.

Compared with the prior art the beneficial effects of the utility model: the utility model discloses a battery package is provided with shockproof mechanism, when making the battery package fall to ground or hard object from the eminence, because shockproof mechanism's existence can play the cushioning effect to the group battery, effectively prevents that the battery from being damaged because strong vibrations, and can set up the through-hole on some bumper shock absorbers, is favorable to the flow of air, good heat dissipation.
