Electric bicycle battery device with damping structure

Abstract

The invention relates to an electric bicycle battery device with a damping structure. The box body is arranged at the upper end of a base, a heat dissipation cavity is formed in the box body, heat dissipation holes are formed in the inner wall of the heat dissipation cavity, a second movable cavity allowing the box body to move is formed in the upper end of the base, a second piston is arranged atthe bottom in the second movable cavity, and a piston shaft is arranged on the side, close to the box body, of the second piston; a first piston is arranged on one side of the piston shaft and fixedto the box body, and a spring is arranged between the first piston and the second piston and connected to the periphery of the piston shaft in a sleeving mode. A box body is arranged at the upper endof a base, a heat dissipation cavity is formed in the box body, heat dissipation holes are formed in the inner wall of the heat dissipation cavity, a second movable cavity allowing the box body to move is formed in the upper end of the base, a second piston, a piston shaft and a third piston are arranged at the bottom in the second movable cavity, the piston shaft stretches between the second piston and the third piston, and a spring is sheathed on the periphery of the piston shaft, and by utilizing the elastic restoring force of the spring, the shock absorption performance of the battery in use can be effectively improved, so use stability of the battery device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an electric bicycle battery device with a shock absorbing structure. Background technique [0002] As a new type of means of transportation, electric bicycles have seen a sharp increase in market demand in recent years, and their portability and light weight are welcomed by users. Become one of the new travel tools after the bicycle. So there are a wide variety of scooters on the market. And along with the product refinement of electric bicycle, when some electric bicycles used for cross-country use, the damping performance of its battery is not good, causes the power supply stability of electric bicycle to be affected when using, so it is urgent to develop a kind of electric bicycle with An electric bicycle battery device with a shock-absorbing structure solves the problems in the prior art. Contents of the invention [0003] The object of the present invention is to prov...
