Problems solved by technology

[0004] However, in some cases, even if the airbag is installed, it is impossible to avoid serious collision between the driver and the steering wheel, resulting in casualties of the driver. Collision with the steering wheel; another example, unknown damage to the airbag prevents the airbag from deploying and the driver collides with the steering wheel

Embodiment 1

[0067] On the basis of a release mechanism 30 with a driving column 31 and a driven body 32, such as Figure 1 to Figure 6 As shown, the release mechanism 30 is additionally provided with a ball 33 and a buckle cover 34 . In this embodiment, a second tapered hole 325 is defined on the end surface of the second end of the driven body 32 . The sphere 33 is arranged in the second tapered hole 325; the button cover 34 covers the part of the end surface of the second end of the sphere 33 protruding from the driven body 32, and the button cover 34 is screwed with the driven body 32; wherein: the button cover 34 is made of aluminum material. This embodiment is suitable for the case where the deformation resistance of the elastic flap 321 is small (when the deformation resistance of the elastic flap 321 is small, when the actual pressure on the steering wheel is much lower than the preset pressure, the elastic flap 321 can cause the protrusion 323 to break away In the case of the sl...

Embodiment 2

[0070] On the basis of a release mechanism 30 with a driving column 31 and a driven body 32, such as Figure 7 to Figure 10 As shown, the release mechanism 30 also adds a ball 33 and a telescopic mechanism. A second tapered hole 325 is defined on the surface of the second end of the driven body 32 . The ball 33 is disposed in the taper hole; the telescopic mechanism includes: a base 351 , a first spring 353 and a telescopic strip 352 . The seat body 351 is fixed on the second end surface of the driven body 32; the first spring 353 is arranged in the seat body 351; one end of the telescopic strip 352 extends into the seat body 351, and the other end extends out of the seat body 351 to stop the ball 33 spheres. In the present invention, the ball 33 is used to support the elastic petal 321 to provide deformation resistance for the elastic petal 321 . The working process of the release mechanism 30 of this embodiment is: when the actual pressure received by the steering wheel i...

Abstract

The present invention discloses a steering device, which comprises a steering shaft, a steering wheel and a driving rod. The steering shaft comprises a shaft tube, a shaft lever and a release mechanism. The shaft tube has a first end and a second end, and the second end of the shaft tube is directly or indirectly connected with the driving rod. the shaft lever has a first end and a second end; thesteering wheel is mounted at the first end of the shaft lever, and the second end of the shaft lever extends into the shaft tube from the first end of the shaft tube; the release mechanism is used for limiting axial movement of the shaft lever relative to the shaft tube when an actual pressure on the steering wheel is less than a preset pressure, and releasing the restriction on the shaft lever when the actual pressure on the steering wheel is greater than the preset pressure, and the shaft lever retracts towards the second end of the shaft tube.

Description

technical field [0001] The invention relates to the technical field of steering of mobile vehicles, in particular to a control system for providing hydraulic power assistance. Background technique [0002] It is known that all mobile vehicles have a steering system, and the steering system in the prior art generally includes: a mechanical transmission part and a hydraulic power assist part. Specifically, the mechanical transmission part includes a steering wheel, a steering shaft, and a drive rod. The steering wheel is installed on the upper end of the steering shaft, and the drive rod is directly or indirectly connected to the steering shaft. The drive rod is used to drive the wheel hub to steer; Assists in the turning of the steering wheel. [0003] For high-speed moving vehicles, such as cars, in order to prevent the driver from bumping into the steering wheel when the vehicle collides, a safety belt is added to the driver's seat, and a safety air bag is set on the steer...
