Battery box structure of electric bicycle

Abstract

The invention discloses a battery box structure of an electric bicycle. The battery box structure comprises a frame lower tube, wherein a battery box is placed in the frame lower tube, the front end of the battery box is connected with a spring, the spring is fixed at the front end inside the frame lower tube through a spring fixing plate, the battery box is fixed at the tail end inside the frame lower tube through a screw, the rear end of the battery box is also closely connected with a controller through a screw, a controller fixing plate is sheathed on the controller, and a plurality of pieces of foam which play a role of damping are pasted on a shell of the battery box. The battery box structure adopts a rear battery structure, and the frame lower tube inclines upwards so as to prevent rainwater from pouring into a frame from the front part and protect an internal electrical system to the maximum extent. A battery is convenient to disassemble, and can be easily replaced by only opening a rear end cover; graceful lines are formed by the overall radian of the battery box structure so as to increase the visual impact; and the design is fully integrated with human mechanics concepts, and the radian of the whole vehicle accords with human engineering.

Description

technical field [0001] The invention belongs to the field of electric bicycles, and in particular relates to a battery box structure of an electric bicycle. Background technique [0002] The existing electric bicycle is placed in a split type, and the shape is straight. The battery box is a plastic or aluminum profile structure: the battery is loaded from the front, inserted into the rear of the tube wall of the frame, and positioned with the seat tube installation position of the frame As a standard, the PVC plastic sleeve is inserted into the down tube of the frame, and it is wrapped around the front fork stem tube, and the PVC plastic sleeve is used as a compression. The design method of loading the battery from the front has great defects: the assembly form is fixed, and the battery must be loaded into the frame first, then the front fork and T handlebar, and then the lamp; it is extremely difficult to disassemble. It is cumbersome, you need to remove the light first, t...

AI Technical Summary

Problems solved by technology

The design method of loading the battery from the front has great defects: the assembly form is fixed, and the battery must be loaded into the frame first, then the front fork and T handlebar, and then the lamp; it is extremely difficult to disassemble. It is cumbersome, you need to remove the light first, then the front fork and T handlebar, and finally remove the battery, which is extremely inconvenient to replace the battery; it will be extremely troublesome to repair the battery pack or controller; the battery is not good at preventing theft and is easy to place outdoors lost

[0003] In terms of waterproof function, the existing technology is also insufficient, and the battery placement method is also problematic. It is loaded from the front, and the front is high and the rear is low, and there are many connections. Penetrating from front to back, if you ride in rainy weather, rainwater is easy to enter from the front, which brings safety hazards to the battery and controller, because there is a large assembly gap in the front, its structure is not tight, if the battery explodes under extreme conditions Rush out from the front, and the front is open, and the distance from the front of the driver is very close, which will affect the safety of driving
