AI Technical Summary

Technical Problem

The existing steering column structure has problems such as difficulty in ensuring lateral and vertical clearances, and a wide variety of parts with high costs.

Method used

The steering column is made of aluminum alloy and has cylindrical protrusions and rotating blocks on both sides. The rotating blocks are slightly interference-fitted with the slide rails, eliminating the need for bolts and nuts. The displacement of the rotating blocks is limited by the closed groove slide rails.

Benefits of technology

The lateral and vertical clearances of the steering column assembly were reduced, improving mechanical performance and reducing the number of parts and cost.

Since the types of parts are many, and each part is a moving part, the gap in the horizontal and vertical directions of the steering column assembly cannot be guaranteed, and the cost is high. CONTENT OF THE UTILITY MODEL

[0003] The utility model is just in view of the above problem, make up the deficiency of prior art, provide a novel steering column pipe, the utility model discloses can reduce the gap in the horizontal and vertical directions of the steering column, and cancel the bolt and the nut simultaneously, reduce the product cost.

[0004] To achieve the above object, the utility model adopts the following technical scheme.

[0005] The utility model provides a novel steering column pipe, including the steering column and the steering column side plate being arranged at both sides of the steering column, and its characterized in that, both sides of the steering column have the cylindrical convex structure at the position corresponding to the steering column side plate, and the rotating block is arranged on the cylindrical convex structure, the slide is arranged in the steering column side plate and matched with the rotating block, and the rotating block is limited in the slide and can slide along the slide.

[0006] Further, the slide is the closed notch structure, so that the rotating block is axially limited displacement by the steering column side plate after the steering column and the steering column side plate are assembled.

[0007] Further, the cylindrical convex structure and the rotating block, and the rotating block and the slide of the steering column side plate are all small interference fit.

[0008] Further, the rotating block adopts nylon material.

[0009] Further, the steering column is made of aluminum alloy material and is integrally formed by pressure casting.

[0010] The utility model has the beneficial effects.

[0011] The utility model discloses can eliminate the clearance of traditional structure steering column pipe and steel sleeve, and further reduce the transverse and vertical clearance of steering column assembly, improve the mechanical property of steering column assembly, and cancel the use of bolt and nut, reduce the number of parts, reduce the cost of steering column. BRIEF DESCRIPTION OF DRAWINGS

[0012] In order to make the technical problem, technical scheme and beneficial effect solved by the utility model more clearly, the following is in combination with the specific embodiment, and the utility model is further detailed.The specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.
