Problems solved by technology

[0003] At present, most electric folding bicycles are battery-mounted, and their appearance is similar to that of bicycles or converted from bicycles. The frame is folded by setting a folding mechanism and quick-release fasteners between two frame tubes. The frame is folded in half horizontally, the folding process is complicated, and the appearance is not beautiful after folding. Moreover, the battery pack of this type of electric folding car with external batteries is relatively large. After folding, the battery pack still remains in its original state and takes up a lot of space, which is not conducive to storage in the car. In a small space such as the trunk, it is not conducive to long-distance movement
[0004] There are also some electric folding bicycles with built-in batteries, that is, the batteries are placed in the frame, which saves the external space occupied by the battery pack. However, the frame of this electric folding bicycle cannot be folded, and the folding of the electric folding bicycle has not been effectively improved. volume problem

Embodiment Construction

[0026] Such as Figure 1-8 Shown: a vehicle frame of an electric folding bicycle according to the present invention, including a handlebar frame 1, a seat tube 2 and a pedal 3, the handlebar frame 1 is connected to the pedal 3 shafts, the pedal 3 is connected to the seat tube 2 shafts, and the seat tube 2 is arranged Limiter.

[0027] In this solution, the limiting device provided on the seat tube 2 includes a limiting frame 4, and the limiting frame 4 is arranged on the bottom surface of the pedal 3 through a compressed elastic device.

[0028] The compression elastic device can be a compression spring, and a positioning column 5 is set on the bottom surface of the pedal 3. The limit frame 4 and the positioning column 5 are connected by a compression spring. The compression spring has good shrinkage and rebound ability, and can effectively control the limit. Locking and unlocking of frame 4.

[0029] The outer circumference of the compression spring is provided with a sleev...

Abstract

The invention discloses a frame of an electric folding bicycle, which comprises a handlebar frame, a seat tube and a pedal, and is characterized in that: the handlebar frame is connected with the pedal shaft, the seat tube is connected with the pedal shaft, bit device. The frame of the electric folding bicycle of the present invention is composed of a handlebar frame and a pedal. The pedal can be folded up and down relative to the handlebar frame, and the seat tube can be folded up and down relative to the pedal. During the folding process of the vehicle, only the seat tube and the pedal need to be folded , the folding process of the whole frame only needs two steps, and it does not take a few seconds. It is extremely convenient to carry, go up and down stairs, store, and charge.

Description

technical field [0001] The invention belongs to accessories of folding bicycles, in particular to a vehicle frame of electric folding bicycles. Background technique [0002] The electric folding car has the advantages of being foldable, easy to control, and easy to carry. During the folding process, it does not need to use external tools. The car can be folded or unfolded manually. After folding, it can be stored and moved more conveniently, avoiding outdoor Unsafe hidden dangers of storage. [0003] At present, most electric folding bicycles are battery-mounted, and their appearance is similar to that of bicycles or converted from bicycles. The frame is folded by setting a folding mechanism and quick-release fasteners between two frame tubes. The frame is folded in half horizontally, the folding process is complicated, and the appearance is not beautiful after folding. Moreover, the battery pack of this type of electric folding car with external batteries is relatively lar...
