AI Technical Summary

Technical Problem

The existing electric bicycle lithium battery sealing structure is prone to loosening of bolts and threaded holes during use, resulting in a reduction in sealing performance and the internal high temperature cannot be effectively dissipated.

Method used

The structural design of the battery box and cover plate is adopted. The sealing plate, connecting plate, movable tube, clamping rod, pulling cover, compression spring and other components are used to fix and seal the cover plate, and the design of the heat dissipation hole and shield plate is achieved. , automatically adjust the opening and closing of the heat dissipation hole by temperature changes.

Benefits of technology

Effectively prevent the cover from loosening, improve the sealing of the battery box, and quickly dissipate the internal high temperature by automatically adjusting the heat dissipation hole, improving the service life and safety of the battery.

Abstract

The utility model relates to the technical field of electric bicycle lithium batteries, in particular to an electric bicycle lithium battery sealing structure which comprises a battery box body and a cover plate, a sealing plate is fixedly connected to the bottom of the cover plate, a connecting plate is fixedly connected to the outer side of the cover plate, and a movable pipe is fixedly connected to the outer side of the connecting plate. A clamping rod is movably connected to the interior of the movable pipe, a pulling cover is fixedly connected to the outer side of the clamping rod, a compression spring is fixedly connected to the inner side of the pulling cover, a positioning hole is formed in the battery box body, an L-shaped plate is fixedly connected to the outer side of the battery box body, and a threaded pipe is fixedly connected to the outer side of the L-shaped plate; the lithium battery box is simple in structure and convenient to use, the situation that the leakproofness of the lithium battery box is weakened due to the fact that connection between the bolt and the threaded hole is loosened can be prevented, and meanwhile high temperature in the lithium battery box can be rapidly dissipated out.
