Electric vehicle battery fixing structure and electric vehicle

Abstract

The invention relates to an electric vehicle battery fixing structure and an electric vehicle. The electric vehicle battery fixing structure comprises a vertical pipe, a rear shaft fork frame and a tubular battery positioning assembly. The tubular battery positioning assembly comprises two positioning pipes arranged in parallel, two reinforcing plates fixedly connected between the two positioning pipes, supporting pipes fixedly connected between the rear shaft fork frame and the reinforcing plates, a battery main body connected with the positioning pipes in a sliding manner, and battery fixing plates arranged in the middles of the reinforcing plates; the battery fixing plates are capable of moving in a longitudinal direction and tightly abutting against the lower surface of the battery main body. According to the invention, the modeling space is fully and reasonably utilized, so that the whole vehicle is light, small in size and simple and fashionable in appearance, and the arrangement of the reinforcing plates can effectively disperse the stress of the positioning pipes, improve the stress condition and improve the supporting strength of the positioning pipe; the battery fixing plates can increase contact points with the battery main body in the driving process, so that shaking of the battery main body on the positioning pipe can be effectively reduced, the battery main body is prevented from being damaged when driving on a bumpy road surface, and the service life of the battery is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle battery fixing structure and the electric vehicle. Background technique [0002] Because electric bicycles have the characteristics of fast riding speed, time-saving and labor-saving, they are more and more favored by consumers and have become a reliable travel tool for people. The driving power of the electric bicycle comes from the battery. The performance of the battery directly affects the power and economy of the electric vehicle. Its installation position is between the standpipe and the rear frame of the electric vehicle frame, and is close to the standpipe. Or it can be taken and placed under the sheet metal of the vehicle frame behind the electric vehicle, and a storage box is installed above the sheet metal of the vehicle frame. [0003] As the core mechanism of electric vehicles, the convenience of battery storage and disassembly, and the...

Problems solved by technology

[0003] As the core mechanism of electric vehicles, the convenience of battery storage and disassembly, and the simplified battery positioning structure to make the whole vehicle light and small have attracted more and more people's attention. Today, the improvement of the battery fixing structure has the following deficiencies: First, for the application scenarios with large battery specifications, when simplifying the battery positioning structure, it is easy to cause the frame structure to be unstable due to concentrated force; second, there is a certain space between the battery and the frame after installation, resulting in the Shaking inside the frame and colliding with the frame will easily damage the battery and affect the service life of the battery
