CN202743317U - Steering wheel - Google Patents

Abstract

The utility model relates to a steering wheel and aims to provide a steering wheel with a plastic skeleton. The steering wheel comprises a steering wheel body; the steering wheel body comprises the plastic skeleton; a plurality of joints are arranged on the skeleton wall and in the extension direction of the skeleton; all the joints are a plurality of ribs extending outwards on the skeleton wall; a plurality of ribs are uniformly distributed in the peripheral direction of the skeleton; the skeleton is coated with a skin; and a foam material is filled between the skin and the skeleton. The steering wheel has the beneficial effects that when the collision occurs to a vehicle, the impact to a human body is weakened and the damage to passengers is reduced; and the steering wheel is suitable to popularize and use.

Description

Bearing circle

Technical field

The utility model relates to a kind of vehicle part, relates in particular to a kind of bearing circle.

Background technology

The skeleton of bearing circle on the market is metallic framework, and intensity is too high, and in vehicle collision accident, bearing circle contact human body will directly damage human body, and the metallic framework bearing circle has increased the injures and deaths risk of chaufeur.

China Patent Publication No. CN1572620A discloses a kind of bearing circle, it has wheel hub mounted portion, wheel disc and a plurality of spoke, spoke one end is fixed on the described hub mounted portion of taking turns, the other end is fixed on the described wheel disc, be extended with strengthening part between described spoke, strengthening part utilizes the one end to form elastic portion at described spoke.This bearing circle remains metallic framework, and is when vehicle collision occurs, larger to the human injury.

The utility model content

The purpose of this utility model is to provide a kind of bearing circle of plastic skeleton, when solving the generation vehicle collision that exists in the background technology, and the problem that bearing circle is larger to the human injury.

To achieve these goals, the technical scheme of the utility model bearing circle is: a kind of bearing circle, comprise the bearing circle body, described bearing circle body comprises plastic skeleton, on the described skeleton wall, be provided with some joints at its bearing of trend, each joint is all for by a plurality of muscle that extend outward on the skeleton wall, and described a plurality of muscle are circumferentially uniform skeleton, skeleton is coated with covering, is filled with expanded material between covering and the skeleton.The mentality of designing of this technical scheme is: skeleton adopts plastic material, and when collision happens, bearing circle is to the damp impacts of human body, reduced occupant's injury, this is for to arrange joint at the skeleton wall, increases the area of contact with expanded material, but the intensity of reinforced plastics skeleton and elasticity.

As preferably, described skeleton and the joint on it are formed in one.Skeleton and joint are one-body molded by Shooting Technique, and be easy to make, and intensity is better.

As preferably, described skeleton and the joint on it are PC or ABS material.

The beneficial effect of the utility model bearing circle is: when vehicle collision, to the damp impacts of human body, reduced the injury to the occupant.

Description of drawings

Fig. 1 is a kind of structural representation of the utility model bearing circle;

Fig. 2 is the sectional schematic diagram of bearing circle wheel disc.

Number in the figure is respectively: 1. bearing circle body 2. skeletons 3. coverings 4. expanded materials 5. joints.

The specific embodiment

Also by reference to the accompanying drawings the technical solution of the utility model is further described specifically below by embodiment.

Embodiment:

A kind of bearing circle, as shown in Figure 1, comprise bearing circle body 1, described bearing circle body 1 comprises skeleton 2, on described skeleton 2 walls, be provided with some joints 5 at its bearing of trend, as shown in Figure 2, each joint 5 is all for by four muscle that extend outward on skeleton 2 walls, described four muscle are circumferentially uniform skeleton 2, described skeleton 2 and the joint 5 on it are formed in one, described skeleton 2 and the joint 5 on it are the PC material, and skeleton 2 is coated with covering 3, is filled with expanded material 4 between covering 3 and the skeleton 2.

When collision happens, bearing circle has reduced occupant's injury to the damp impacts of human body.

Above-mentioned described specific embodiment only is that the preferable examples explanation is done in design of the present utility model.All any modifications of making within spirit of the present utility model and principle or replenish or be equal to alternatively all should be included within the protection domain of the utility model claim.

Claims (3)

1. bearing circle, comprise bearing circle body (1), it is characterized in that: described bearing circle body (1) comprises plastic skeleton (2), on the described skeleton wall, be provided with some joints (5) at its bearing of trend, each joint (5) is all for by a plurality of muscle that extend outward on the skeleton wall, described a plurality of muscle is circumferentially uniform skeleton (2), and skeleton (2) is coated with covering (3), is filled with expanded material (4) between covering (3) and the skeleton (2).

2. bearing circle according to claim 1 is characterized in that: described skeleton (2) is formed in one with joint (5) on it.
