Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle hubs, and in particular to an electric vehicle hub structure that is not easily deformed. Background Art

[0002] An electric vehicle is a means of transportation that uses electricity as its main power source. It uses batteries to provide energy to drive the electric motor, which in turn propels the vehicle. Electric vehicles have the advantages of being environmentally friendly, energy-saving, and low-noise, and therefore are receiving more and more attention and promotion around the world.

[0003] There are many types of electric vehicles, including electric bicycles, electric motorcycles, electric cars, electric buses, etc. Among them, electric bicycles are the most commonly used.

[0004] The common structure on the electric bicycle is the hub body, which is generally composed of spokes, a rim, and a center column. The vacuum tire is then sleeved and installed on the hub body, and the vacuum tire contacts the ground.

[0005] When the driver is driving an electric bicycle, if he suddenly encounters a pedestrian or a child in front, the driver will brake quickly. At this time, the electric bicycle itself will lean forward in the driving direction. At this time, all the weight of the electric bicycle and the driver are applied to the front tire hub of the electric bicycle. If the structure of the front tire hub is unstable, encountering similar emergency braking situations for a long time will cause the front tire hub of the electric bicycle to deform and age.

[0006] Therefore, an electric vehicle wheel hub structure that is not easily deformed is needed to solve the above problems.

[0007] In addition, the spokes of existing electric vehicle hubs have low rust-proof, corrosion-resistant and heat-insulating protection properties. Utility Model Content

The outer supporting ribs, spoke main supporting ribs and spoke secondary supporting ribs are all made of fiberglass board material and are three millimeters thick. The triangular structure is stable, strong, does not deform, and is durable.
