Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of energy storage battery, especially to an end plate for fixing energy storage battery. BACKGROUND

[0002] The existing energy storage battery of new energy vehicle is generally provided with end plates at both ends, which are used for fixing the energy storage battery and playing a protective role. The connection mode of the end plates and the energy storage battery is as follows: the two end plates are placed at both ends of the energy storage battery, and then the steel cable ties are used to bind them together. The steel cable ties are connected with the insulating tubes, the length of which is greater than that of the energy storage battery and corresponds to the energy storage battery. The two ends of the insulating tubes generally extend to the outside of both ends of the energy storage battery and correspond to the side surface of the end plate. In this way, a good insulating and protective effect can be achieved. When the steel cable ties are tightened and bound, the insulating tubes will be rubbed with the end plate, which will cause damage and affect the protective performance. SUMMARY

[0003] In order to overcome the technical defects of the prior art, the purpose of the utility model is to provide an end plate for fixing energy storage battery to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problems is as follows:

[0005] According to one aspect of the utility model, an end plate for fixing energy storage battery is designed, which comprises: an end plate body, a positioning groove for positioning the binding position of the steel cable tie is arranged on the front side of the end plate body, and an avoiding groove for placing the end part of the insulating tube on the steel cable tie is arranged on the rear side of the left and right sides of the end plate body. The transverse width of the avoiding groove is not less than the wall thickness of the insulating tube.

[0006] By arranging the positioning groove on the end plate body, the position of the steel cable tie can be positioned by cooperation of the steel cable tie and the positioning groove, so as to ensure that the binding position of the steel cable tie is uniform and firm. The avoiding groove is arranged on the rear side of the left and right sides of the end plate, and the end part of the insulating tube on the steel cable tie is reserved in the avoiding groove. The transverse width of the avoiding groove is controlled to be not less than the wall thickness of the insulating tube. When the steel cable tie is tightened and bound, the end part of the insulating tube is located in the avoiding groove and contacts with the side wall of the avoiding groove or keeps a gap, so that friction between the end plate body and the end part of the insulating tube is avoided, thereby preventing the end part of the insulating tube from being rubbed and damaged with the end plate body at the contact position when the steel cable tie is bound, and ensuring that the insulating and protective performance of the insulating tube is not affected.

[0009] In some embodiments, a mounting hole is arranged on the front side of the left and right ends of the end plate body respectively. When the terminal seat needs to be fixed by inserting the upper end of the end plate, the threaded end of the screw is screwed into the threaded hole on the terminal seat to fix the terminal seat.

[0010] In some embodiments, a long strip-shaped lifting hole is arranged on the front side of the end plate body. Thus, the end plate and the energy storage battery can be lifted and transferred through the lifting hole.

[0011] In some embodiments, a vertical rib is arranged on the front side of the left and right ends of the end plate body respectively, each rib is composed of three sections, and the gap between adjacent sections forms the positioning groove.

[0012] In some embodiments, the avoidance groove vertically penetrates the end plate body.

[0013] In some embodiments, two oval-shaped through holes are arranged on the left and right ends of the end plate body respectively.

[0014] In some embodiments, a heat-conducting silicone grease layer or a heat-conducting sponge sheet is attached to the rear side of the end plate body. Thus, the heat-conducting silicone grease layer or the heat-conducting sponge sheet can ensure the heat-conducting and heat-dissipating effect between the end plate body and the energy storage battery.
