Description

A-shaped electric bicycle rear fork support

Technical Field

The utility model relates to an electric bicycle technical field particularly, relates to a A font electric bicycle rear fork support.

Background

The bicycle is a tool which is used for replacing the walking in common nowadays, and the bicycle mainly comprises a manual bicycle and an electric bicycle. A manual bicycle, also known as a bicycle or bicycle, is generally a two-wheeled small land vehicle. After a person rides the vehicle, the person steps on the pedal as power, and the vehicle is a green and environment-friendly vehicle. The electric bicycle is a vehicle which takes a storage battery as an auxiliary energy source, is provided with a motor, a controller, the storage battery, a rotating handle brake handle and other operating components and a display instrument system on the basis of a common bicycle.

Along with the rise of the existing electric bicycles, the small and exquisite electric bicycles are used more, especially the electric bicycles for driving and the like are required to be short, short and narrow, so that the electric bicycles can be conveniently placed on a car trunk or other vehicles for carrying. The rear fork support mounting shock absorbers of the traditional electric bicycle are all installed in a mode of inclining to the upper top, and most of the shock absorbers are installed in a mode of inclining to the upper top.

For example, the prior patent publication No. CN1090125C discloses a bicycle frame having two mold assemblies that are identical to each other and can be connected in at least two different positions, making it suitable for use not only in men's vehicles but also in women's vehicles. Each mould assembly being V-shaped, having an apex and first and second arms projecting from the apex, the first and second arms forming an angle of 60 ° with respect to each other, at least the second arm being fork-shaped, wherein the second mould assembly is arranged at a rear position of the frame with its top in the lower region and the first and second arms extending in a direction towards the upper and rear regions, respectively, and the first mould assembly is selectively arranged at a front position of the frame with its apex abutting the front region and the first and second arms extending in a direction towards the lower and upper regions, respectively, to form a first spatial orientation; or its top abuts against the lower region and the first and second arms extend in a direction towards the front region and the upper region, respectively, to form a second spatial orientation. Its second arm carries out the shock attenuation through the bumper shock absorber, and the bumper shock absorber slope sets up, and when the shock attenuation, the personnel of riding are great in the wobbling range of vertical direction, influence its comfort level of riding.

The design can not meet the requirements of small size and short wheelbase for the electric bicycle for riding on behalf of a user.
