Center battery box

Abstract

The invention provides a center battery box, belongs to the technical field of electric bicycle accessories, and solves the problem that the existing battery box is inconvenient to mount. The center battery box is arranged in the position of a bottom bracket of an electric bicycle, and comprises a main body; a first containing tank for containing a unit battery cell module is formed inside the main body; a center shaft hole is formed in the main body; the center shaft hole penetrates through the main body; and the shape and size of the center shaft hole are matched with those of a center shaft arranged in the position of the bottom bracket. The center battery box ensures that a battery and a controller are integrated on a battery box, and the center shaft hole matched with the center shaft in the position of the bottom bracket of the electric bicycle is formed in the battery box, so that the shape of the electric bicycle adopting the center battery box is more compact and attractive; a controller cover plate and a battery box cover plate are provided, so that a battery pack and the controller are convenient to dismount, replace and maintain; and the center battery box increases the difficulty in stealing the battery after being applied to the electric bicycle, thereby having an anti-burglary function. The center battery box is more convenient to mount and more stable in quality.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle accessories and relates to a middle battery box.

[0004] Due to the limitation of the battery box setting of the existing electric bicycle, it can genera...

AI Technical Summary

Problems solved by technology

[0004] Due to the limitation of the battery box setting of the existing electric bicycle, it can generally only be arranged on the back seat of the electric bicycle or the middle tube of the vehicle frame. This design has some defects: it greatly takes up the design space of the electric bicycle, and makes the electric bicycle The back seat of the bicycle cannot carry people or objects, which affects the use efficiency of the electric bicycle; affects the appearance of the electric bicycle; is often exposed to the sun or rain, which affects the service life of the battery box (group); it is easy to be stolen by thieves
