Embodiment approach

[0030] In this embodiment, the above-mentioned first wrapping layer 3 can be made of polyurethane foam material. Polyurethane foam materials can be specifically formulated with polyester polyol or polyether polyol and MDI (diphenylmethane diisocyanate) or TDI (toluene diisocyanate). The hardness of the coating layer can be adjusted according to the actual needs of the product. Changing the mix ratio of the combined materials can adjust the hardness of the surface of the steering wheel to improve the feel of holding the steering wheel.

[0031] In one embodiment of the automobile steering wheel of the present invention, the steering wheel frame 1 includes the first spoke 12 and the second spoke 13 arranged on both sides of the central part 16, and the spokes arranged on the first spoke 12 and the second spoke. Between the third spoke 14 and the fourth spoke 15, the first spoke 12 and the second spoke 13 are arranged in the same straight line, the third spoke 14 and the fourth s...

Abstract

The invention provides a steering wheel of a car. The steering wheel of the car comprises a steering wheel frame and a steering wheel protective cover. The steering wheel protective cover aids in protecting the steering wheel frame. The steering wheel frame comprises at least three spokes, a rim, and a central part connecting the three spokes respectively and is injection-molded from modified composite material. The steering wheel frame is injection-molded from modified composite material which is high in strength and flowability, so that when an accident happens to the car to cause violent crash, the body of the driver violently collides forward with the steering wheel, the steering wheel deforms properly, and the driver is prevented from serious damage. On the other hand, the steering wheel protective cover and the steering wheel frame are integrally formed by foaming. Foams of the steering wheel formed by foaming aid in protecting the injected steering wheel frame well, and accordingly the steering wheel frame is guaranteed not to deform greatly when hit by impact force.

Description

technical field [0001] The invention relates to the field of automobile steering control systems, in particular to an automobile steering wheel. Background technique [0002] The existing automobile steering wheel frame is usually die-cast or welded, and belongs to the metal frame structure. The steering wheel frame made of this metal is extremely hard and rigid, and it is not easy to deform when it is impacted by a soft object. However, when the car has an unexpected strong collision, the driver's body will suddenly and violently move forward to hit the steering wheel. Due to the excessive rigidity of the steering wheel, the driver's body will be severely impacted by the steering wheel, causing bruises. In severe cases, the driver's bones and muscles will be broken, the internal organs will be seriously damaged, and even life-threatening. Contents of the invention [0003] In order to solve the problem in the prior art that the driver's body collides with the steering wh...
