Electric bicycle battery with cylindrical battery module

Abstract

The invention discloses an electric bicycle battery with a cylindrical battery module, and the battery comprises a protective shell; a plurality of heat dissipation holes are formed in the circumferential surface of the protective shell, the outer wall of the protective shell is wrapped with a heat dissipation plate, an extension rod is arranged on the inner side of the heat dissipation plate in an extending mode, and one end of the extension rod penetrates into the protective shell through the heat dissipation holes; a fitting plate is fixedly arranged at one end of each extension rod, and abattery module is slidably embedded in the inner side of the protective shell. Through the heat dissipation plate, the heat preservation shell, the extension rod and the filling layer, the heat generated by charging of the battery module can be collected and utilized, the situation that the discharging efficiency of the battery module is reduced due to the low temperature of the external environment is avoided, and the endurance mileage of the battery module is further increased; through a power receiving block, a power receiving cylinder and an electrode, the stable electrical connection of the battery module can be realized, unstable electrical connection caused by shaking is avoided, and the working stability of the electric bicycle battery of the cylindrical battery module is further improved.

Problems solved by technology

[0003] With the popularity of electric bicycles, more and more manufacturers begin to pay attention to their own technical advantages. However, due to the limitation of battery technology, the existing electric bicycles have limited battery life. Once a breakthrough is made in the battery life, the consumption of Because the existing battery modules generate a lot of heat when charging, on the one hand, it is not conducive to the safety of charging; The discharge efficiency of the group is reduced. Secondly, the use environment of the existing electric bicycle is relatively complicated, which will generate a large amount of vibration, resulting in poor stability of the electrode connection of the motor module. After a long period of use, it is very likely to cause a sudden power failure during use.
