Abstract

The invention relates to an assembly structure of an automobile steering post. The assembly structure comprises a steering post component, an upper bracket component and a lower bracket body. The assembly structure is characterized in that a lower bracket limit block, a lower bracket and the lower bracket body are riveted together through rivets; the lower bracket body positioned at the side of the lower bracket limit block is provided with a limit groove; simultaneously, the lower bracket body is provided with a rivet sliding guide groove; an upper bracket of the upper bracket component is assembled with a slide block; an upper bracket positioning piece is arranged on the slide block; and the upper bracket positioning piece is fixedly connected with the upper bracket through a welding spot. The assembly structure has the advantages that when vehicle has collision, the assembly structure can prevent a steering mechanism and a steering disc causing damage to a driver, thereby reducing injuries and deaths and loss.

Description

Vehicle steering column assembly structure

Technical field

The invention belongs to a kind of automobile turning column assembly, particularly a kind of automobile prevents the vehicle steering column assembly structure that steering hardware damages chaufeur when bumping.

Background technology

At present, adopt the structure that is rigidly connected between the steering hardware of light bus and the vehicle body, safety air bag is not extensively adopting on the light bus or is ejecting under the malfunctioning situation, and when collision happens, steering hardware can directly damage chaufeur together with steering handwheel.

Summary of the invention

The purpose of this invention is to provide a kind of vehicle steering column assembly structure, when collision happens, can prevent that steering hardware and steering handwheel from damaging chaufeur, reduce injures and deaths and loss.

The object of the present invention is achieved like this: it comprises steering column assembly, the upper bracket assembly, the lower bracket body, it is characterized in that: lower bracket limiting stopper, lower bracket and lower bracket body are by rivet together, the side that is positioned at the lower bracket limiting stopper at the lower bracket body is provided with position-limited trough, has rivet on the lower bracket body simultaneously and slides guide groove, assembles slide block on the upper bracket of upper bracket assembly, install the support locations on the slide block, the upper bracket locations is fixedly connected on the upper bracket by solder joint.

Advantage of the present invention is: when collision happens, can prevent that steering hardware and steering handwheel from damaging chaufeur, reduce injures and deaths and loss.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is that the A of Fig. 1 is to view.

Fig. 4 is B-B generalized section of Fig. 1.

The specific embodiment

See Fig. 1-4, concrete structure of the present invention is as follows: lower bracket body 7 is a blanked part, is welded on the steering column assembly 5.The both sides of lower bracket body 7 respectively with the lower bracket limiting stopper 1 of nylon, lower bracket 2 is riveted together by rivet 9, the upper and lower side of lower bracket limiting stopper 1 has vertically bends part, being positioned at lower bracket limiting stopper 1 upper and lower side at lower bracket body 7 vertically bends the part side and is respectively equipped with position-limited trough 10 and blocking-up limit 11, have rivet on the lower bracket body 7 simultaneously and slide guide groove 8, the upper bracket assembly is welded on the steering column assembly 5, the spacing slide block 4 of assembling one end on the upper bracket 6 of upper bracket assembly, assembling upper bracket locations 3 on the slide block 4, upper bracket locations 3 is welded on (Joint Strength guarantees to disconnect by calculating) on the upper bracket 6 by solder joint 12 under certain impact.

Principle of work:

When collision happens, the lower bracket limiting stopper 1 of nylon is subjected to external force, rupture, at this moment, lower bracket 2 is subjected to displacement vertically, upper bracket locations 3 is subjected to external force equally simultaneously, the solder joint 12 of upper bracket locations 3 disconnects, thereby breaks away from upper bracket 6, and slide block 4 breaks away from upper bracket 6, steering handwheel moves forward, thereby can guarantee the personal safety of chaufeur.

Claims

1, a kind of vehicle steering column assembly structure, it comprises steering column assembly, the upper bracket assembly, the lower bracket body is characterized in that: lower bracket limiting stopper, lower bracket and lower bracket body pass through rivet together, and the side that is positioned at the lower bracket limiting stopper at the lower bracket body is provided with position-limited trough, have rivet on the lower bracket body simultaneously and slide guide groove, assemble slide block on the upper bracket of upper bracket assembly, install the support locations on the slide block, the upper bracket locations is fixedly connected on the upper bracket by solder joint.
