Steering wheel capable of protecting belly of driver and commercial vehicle equipped with same

Abstract

The invention relates to a steering wheel capable of protecting the belly of a driver and a commercial vehicle equipped with the same. The steering wheel comprises a steering column, a hub arranged on the steering column, at least one spoke extending outwards from the hub and upwards obliquely, a wheel flange connected with the spoke and an air bag assembly, wherein the air bag assembly comprisesa folded air bag and a gas generator, the wheel flange is provided with a cutting part, and the air bag assembly is arranged on the hub through an installment frame and faces the cutting part exactlyso that the folded air bag can be unfolded towards the cutting part under the action of the gas generator. When rear-end collision happens to commercial vehicles, the steering wheel can well protect bellies, chests and heads of drivers.

Description

technical field [0001] The invention relates to a commercial vehicle, in particular to a steering wheel of the commercial vehicle. Background technique [0002] Most of the steering wheel structure of the car is relatively simple. It is a circular disc with a horn button in the middle. Once a collision occurs, the steering wheel will seriously affect the driver's life safety. The structure of the air bag. Such as the automobile steering wheel published by the Chinese utility model patent with the patent number "ZL02260940.7" and the patent name "automobile steering wheel", and the automobile steering wheel with the application number "95115094.4" and the name "airbag restraint system integrated with it" The disclosed automobile steering wheel of the application for a patent for invention, they all are by a safety airbag being set in the hub in the middle of the steering wheel, and when a collision occurs, the airbag upwards expands along the steering wheel to protect the dr...

AI Technical Summary

Problems solved by technology

Although the automobile steering wheel of this kind of structure can play the effect of protecting the driver's head, it can only be used for cars with an inclination angle of the steering wheel between 25 degrees and 30 degrees. Vehicles include heavy trucks, light trucks, passenger cars, etc.), because the inclination angle of its steering wheel is between 70 degrees and 85 degrees, if the above-mentioned steering wheel is set on a commercial vehicle, because the inclination angle is too large, there is no protection for the driver. In the event of a rear-end collision of a commercial vehicle, the driver moves forward, and the abdomen will directly hit the steering wheel rim, causing the steering wheel rim to insert into the driver's abdomen, causing serious injury or even death to the driver

At present, there is no effective solution to the abdominal injury of commercial vehicle drivers in domestic commercial vehicles. According to the research on many commercial vehicle collision accidents, a steering wheel that can protect the driver's abdomen is invented to reduce the casualty rate and Improving the crash performance of commercial vehicles in China has great significance
