Description

a frame structure

technical field

The invention relates to the technical field of vehicle frames, in particular to a vehicle frame structure.

Background technique

Bicycles are common means of transportation, and are divided into bicycles powered by pedals and electric bicycles driven by electricity.

In order to be able to carry people, a rear hanger is usually provided at the rear of the bicycle. The layout of the existing rear hanger is shown in Figure 9. The rear hanger 91 is connected with two sets of support rods 92, which are only used to effectively support the rear hanger. The clothes hanger 91 generally has two corresponding support rods on both sides of the tire. At the same time, the rear wheel fender 93 needs to be separately installed with a connecting rod structure 94 for positioning the fender. Therefore, from the perspective of FIG. On the premise, there are three rods (two support rods 92 and one connecting rod structure 94 ). From the perspective of visual perception, the frame in this way is relatively messy and not concise enough.

Another example is the existing published patent document CN203623868U, a rear frame structure of an electric bicycle. Compared with the style shown in FIG. It looks messy and not concise enough.
