Description

Electromagnetic iron attracting device for motor vehicle

The utility model relates to the anti-bundling device of a kind of air-inflation tyre, and in particular for preventing the iron and the ferro-alloy spare of sharp knife edges, wedge angle, burr, for example: iron nail punctures inflated motor tyre.

At present, automobile is fast running on road, be difficult to perceive the wisp on the road surface, and along with industrial expansion, various industrial waste products and the part of losing occur on road, especially ironwork and the various iron nail with sharp knife edges, wedge angle, burr exists everywhere, easy piercing inflating tyre, in a single day the tire of self-propelled vehicle is punctured, and car can't travel, not only economy is suffered a loss but also is wasted time, even the incident that causes a traffic accident.

The purpose of this utility model is that a kind of self-propelled vehicle locking magnet will be provided, and can get rid of iron and ferro-alloy spare on the wheel track, prevents that air-inflation tyre from being punctured.

The purpose of this utility model is achieved in that being provided with the upper end is connected on the car front beam, and the hanger bearing of lower end suspention arc-shaped guide rail, be provided with and be connected on the hanger bearing, has the front arc groove, the arc-shaped guide rail of rear arc groove and the arc-shaped guide rail face in the middle of two grooves, be provided be bearing on the arc-shaped guide rail on, the Rolling hanger of a lower roller and a transverse axis, be provided with the horseshoe electromagnet on the transverse axis that is suspended on Rolling hanger, be provided with two iron blocks that are connected the electromagnet two ends, being provided with an end is connected on the Rolling hanger, the other end is connected on the vehicle front deflector bar, and the energy slide relative, the middle hinge bar alive that also connects two hinges.When wheel travels, electromagnet energising back produces magnetic field, iron block in wheel the place ahead has magnetic, can attract ground-surface iron and ferro-alloy spare, when automobile turned round, the hinge bar of living slided along vehicle front deflector bar, because the function of hinges and the restriction of arc-shaped guide rail, Rolling hanger also can be rotated with front vehicle wheel, remain iron block the place ahead at front vehicle wheel.

Owing to adopt such scheme, the protection motor tire is not punctured, and has reduced economic loss, has avoided driving to mistake and traffic accident, has guaranteed vehicle safety travel.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is an example structure scheme drawing of the present utility model.

Fig. 2 is an embodiment plan sketch of the present utility model.

Fig. 3 is another example structure scheme drawing of the present utility model.

Among the figure: 1. iron block, 2. electromagnet, the 2a. collar, 3. Rolling hanger, 3a. transverse axis, the last roller of 3b., 3b. lower roller, 4. arc-shaped guide rail, 4a. guide pass, 4b. front arc groove, 4c. rear arc groove, 5. hanger bearing, 5a. vertical bar, 5b. connecting panel, 5c. compression spring, 5d. transverse axis, 6. the hinge bar of living, 6a. hinges, 6b. fixed end, 6c. sliding end, 7. car front beam, 8. vehicle front deflector bar, 9. automobile back wheel front-axle beam.

At an embodiment illustrated in figures 1 and 2 is the magnet that is contained in automobile front vehicle wheel the place ahead:

Electromagnet 2 is around the U-shaped core periphery with electrified wire, the top is socketed in collar 2a on the transverse axis 3a of Rolling hanger 3, when running into ground obstacle, and electromagnet 2 transverse axis 3a activity relatively, and two bottom captive joint iron blocks 1, lead is connected 12～36 volts of power voltage supplies of storage battery in the automobile.

Iron block 1 is cylindrical magnetic conduction solid, and overhead about 5 centimetres of bottom can attract ground-surface iron and ferro-alloy spare.

Rolling hanger 3 is to be made of transverse axis 3a, last roller 3b and lower roller 3c.Transverse axis 3a two ends are fixed on the Rolling hanger 3 and arranged on left and right sides plates, last roller 3b and lower roller 3c are connected in the middle of the upper and lower axle, the two ends of upper and lower axle are separately fixed on the forward and backward biside plate of Rolling hanger 3, last roller 3b and lower roller 3c respectively can be relative to upward axle, lower shaft rotate, and the excircle of going up roller 3b and lower roller 3c respectively arc of contact convince the guide pass 4a of rail 4 by patient analysis, can on arc-shaped guide rail 4, make circular arc and roll to guarantee Rolling hanger 3.

Arc-shaped guide rail 4 except with guide pass 4a that upper and

lower roller

3b, 3c contact, also have the movable required corresponding front arc groove 4b and the rear arc groove 4c in forward and backward side of Rolling hanger 3, connecting the vertical bar 5a of hanger bearing 5 in the curved top surface of arc-shaped guide rail 4.According to the automobile angle of turning round is in 45 °, so the arc angle of arc-shaped guide rail 4 is 50 °.

Hanger bearing 5 is to be made of vertical bar 5a, transverse slat 5b and compression spring 5c.Vertically bar 5a is hanging arc-shaped guide rail 4, and transverse slat 5b is fixedly connected on the car front beam 7, and vertically bar 5a can be in the curved top surface hole of horizontal arc-shaped guide rail 4, upper and lower slip, and compression spring 5c is between the curved top surface of connecting panel 5b and arc-shaped guide rail 4.When the upper and lower fluctuation of automobile, because the buffer action of compression spring 5c, iron block 1 upper and lower fluctuation can reduce, and is unlikely overhead too high, and ground is lost magnetic effect, or kiss the earth.

The hinge bar 6 of living is stepped appearance attaching partss, one fixed end 6b is connected on the rear quarter panel of Rolling hanger 3, another slip 6c is connected on the vehicle front deflecting bar 8, in the hinge bar 6 alive two hinges 6a are arranged, when making vehicle front deflector bar 8 promote sliding end 6c side travel, fixed end 6b does circular motion together with Rolling hanger 3 with arc-shaped guide rail 4, keeps iron block 1 all the time in the place ahead of front vehicle wheel.

In addition, when running into road irregularity and changing, for example: the road mire, can adopt spiral, pulley transmission system, make electromagnet 2 around transverse axis 3a or 5d upwards upset lift.

Another embodiment shown in Figure 3 is the magnet that is contained in automobile rear wheel the place ahead, because rear wheel does not turn to, and therefore, does not have arc-shaped guide rail 4 and movable rod 6, but the collar 2a of electromagnet 2 is socketed on the transverse axis 5d of hanger bearing 5, remainder is identical with the structure of front one embodiment.
