In order to achieve the purpose, the utility model adopts the following technical scheme: the utility model provides a polyethylene battery separator with inoxidizing coating structure, includes baffle lining framework, the first base plate of top fixedly connected with of baffle lining framework, the bottom fixedly connected with second base plate of baffle lining framework, first base plate top surface is equipped with first protection damping twill, the bottom surface of second base plate is equipped with second protection damping twill, the side fixed mounting in opposite directions of first base plate and second base plate has the energy-absorbing support bar and strengthens oblique gib block, and strengthens the tip and the energy-absorbing support bar looks fixed connection of oblique gib block.

Preferably, the partition board lining frame body, the first base board and the second base board are all made of polyethylene materials.

Preferably, the side surface of the inner wall of the partition board lining frame body is fixedly connected with the reinforcing oblique lining strip.

Preferably, the energy-absorbing support bars and the reinforcing oblique lining bars are made of ABS plastic materials.

Preferably, the side edges of the spacer bushing body are flush with the side edges of the first and second base plates.

Compared with the prior art, the utility model has the beneficial effects that: this polyethylene battery separator with inoxidizing coating structure, through setting up two plate structure of first base plate and second base plate in the surface of baffle lining frame, and through again between first base plate and the second base plate, the inside energy-absorbing support bar that sets up of baffle lining frame and strengthen the oblique welt, make whole baffle lining frame set up in group battery outside limit, just can support the external force that the battery case struck, it is pressurized through first base plate or second base plate, can contract the energy-absorbing through energy-absorbing support bar and enhancement oblique welt ulcerate, thereby reached and provided the effect of protection buffer protection, avoided outside touch damage battery case and directly threaten inner structure, the security in the application has been improved.
