Description

Vehicle steering with fender guard

Technical field

The utility model relates to a kind of vehicle steering, particularly, relates in particular to a kind of vehicle steering with safety guard.

Background technology

At present, along with developing rapidly of auto-industry, people are also more and more higher to the performance requriements of automobile.And when estimating automotive performance, the safety performance of automobile is one of index of paramount importance.

When estimating the safety performance of automobile, except weighing the performance of automobile under the cruising situation, the more important thing is automobile performance under special circumstances, when for example fierce collision taking place when the automobile overturning or with other objects.

At present, most of automobile steering wheel below all has been equipped with safety air bag, and when violent vibrations took place automobile, air bag just can automatically eject rapidly and finish inflation simultaneously, so that human body and gassiness air bag collide, thereby reaches the effect of buffering.

But; in actual application; adopt the air bag protection still to have a lot of problems; for example air bag can not in time eject when automobile bumps; perhaps air bag ejects too quickly so that feasible personnel by bus because of the impact effect of air bag fracture neck or mandible; therefore, even for the automobile that safety air bag is equipped with in employing, its safety factor is still not high.

In addition, the required expense of air bag device is higher owing to adopting, so safety air bag is not installed by a lot of automobile vendor on vehicle of some low configuration, and with the Control of Automobile manufacturing cost, and then the competitive edge of assurance car load price.Yet this exists great potential safety hazard undoubtedly for the driver of this class vehicle.

Therefore, be necessary in fact to design a kind of new vehicle steering that has safety guard, to overcome above-mentioned defective.

The utility model content

The purpose of this utility model is to provide the vehicle steering that a kind of cost is lower, better safety performance has fender guard.

To achieve these goals, the vehicle steering with fender guard of the present utility model is such design-calculated:

A kind of vehicle steering with fender guard; it comprises ring-type wheel rafter, central part and connects this central part and the spoke of ring-type wheel rafter, described central part comprise lid, be located at the reception room of described lid lower end and be packed in lid and reception room between padded coaming.

Vehicle steering with fender guard of the present utility model is low production cost not only, and has preferable safety performance.

Description of drawings

Below, will be described in more detail the specific embodiment of the present utility model in conjunction with the accompanying drawings, wherein:

Fig. 1 is the birds-eye view that has the vehicle steering of fender guard according to of the present utility model;

Fig. 2 is the side sectional view that has the vehicle steering of fender guard according to of the present utility model.

The specific embodiment

As shown in Figure 1, the vehicle steering 1 with fender guard of the present utility model comprises central part 10, the many spokes 14 that are connected with central part 10 and the wheel rafter 12 that links to each other with described central part 10 by spoke 14.

Please in conjunction with consulting Fig. 1 and Fig. 2, described central part 10 comprises lid 100, be located at the reception room 102 of lid 100 belows and clog padded coaming 104 in reception room 102, and this padded coaming 104 can adopt energy-absorbing foam or other materials similar.

Wherein, the material of described lid 100 is to have elasticity but the plastic cement synthetic material torn easily, and its shape can be less tabular of thickness, and area is advisable with the described padded coaming 104 of abundant covering; The surface of described lid 100 is provided with easy tearing groove 100a, this easy tearing groove 100a is a v-shaped structure, under situation about being subjected to from the external force of bearing circle 1 top, stress concentration can take place at easy tearing groove 100a place in lid 100 suffered pressure immediately, thereby makes lid 100 be torn from this easy tearing groove 100a rapidly; This easy tearing groove 100a is interspersed on lid 100, and in other words, this easy tearing groove 100a is advisable with under being fit to can be torn up easily when bearing circle 1 is being subjected to certain violent pressure in the distribution of lid 100.

The bottom surface of described reception room 102 is connected with the Steering gear (not shown) of automobile, with the enforcement direction of Control of Automobile.These reception room 102 upper body are made by the material with preferable cushion characteristic (for example some plastic materials), thereby make and can in time be cushioned when the upper body of human body and reception room 102 bumps and avoid it seriously injured; The bottom surface of reception room 102 is then made by hard material, firmly is connected between the Steering gear with the bottom surface that guarantees reception room 102 and automobile.

The intensity of described padded coaming 104 for example adopts the energy-absorbing foam with certain intensity with its effective buffering energy-absorbing and simultaneously unlikelyly again be advisable because of itself crossing soft can not effectively protection the when the automobile generation sharp impacts.

See also Fig. 1, wheel rafter 12 is a cirque structure, and it is made by metallic material, takes turns rafter 12 outsides at this and then wraps and be provided with plastic cement or similar material such as wooden.This is taken turns rafter 12 and is provided with many easy folding parts 120 in its circumferencial direction, so that when wheel rafter 12 itself is subjected to severe impact, wheel rafter 12 can fracture rapidly in described easy folding part 120, thereby plays the effect of buffering.

As shown in Figure 1, many spokes 14 are connected between central part 10 and the wheel rafter 12.This spoke 14 is provided with easy tearing part 140 with the junction of central part 10, this easy tearing part 140 can be forms such as banded groove or V-shaped groove body, when wheel rafter 12 and spoke 14 are subjected to severe impact, easily 140 places, tearing part can be torn because of quick stress concentration takes place, and come off fast together with spoke 14 thereby cause taking turns rafter 12.It will be appreciated by those skilled in the art that, the mode of offering of described easy tearing part 140 only just can cause wheel rafter 12 and come off together with spoke 14 when wheel rafter 12 and spoke 14 are subjected to violent impact, and is driving normally or be subjected to can not causing the above-mentioned result of coming off under the situation of slight impact.

Below, the working process with vehicle steering 1 of fender guard of the present utility model will be described when automobile generation sharp impacts:

When automobile generation sharp impacts, the driver can be because of the inertia preshoot, and its health can strike on the wheel rafter 12, and this effect of impact can make that wheel rafter 12 fractures in easy folding part 120 moment, thereby makes that this impact is necessarily cushioned; Subsequently, driver's health can continue preshoot, and this makes spoke 14 be torn from easy tearing part 140, and then makes wheel rafter 12 come off on 10 together with spoke 14 from central division; Behind the process said process, driver's health may effect of impact continue preshoot to central part 10 too strongly, make the lid 100 of this central part 10 to split in its easy tearing groove 100a, the upper body of reception room 102 also can stride because of bump simultaneously, so that driver physical acts on padded coaming 104, this padded coaming 104 absorbs the effect of impact of driver physical fully.

Compare with existing vehicle steering with safety air bag, vehicle steering 1 of the present utility model is not only cheap for manufacturing cost, easy for installation, but also has preferable safety performance.
