Tyre alarm described in the utility model, send alarm sound in the time of both can or occurring waving fault timely and accurately at tire deflation, also can when being uneven the road surface, the vehicle process quit work by the temporary close circuit, in case wrong report, this annunciator is simple in structure, manufacturing, easy to use, with low cost can extensively widely be used in automobile and other association areas.

Fig. 1 is the structural representation of the alarm switch device of annunciator described in the utility model;

Fig. 2 is the structural representation of the alarm controller of annunciator described in the utility model;

Now in conjunction with the accompanying drawings, and pass through following embodiment, annunciator described in the utility model is described in detail.

Annunciator described in the utility model includes alarm switch device 1 and alarm controller as shown in Figure 22 as shown in Figure 1.As shown in Figure 1, alarm switch device described in the utility model, include switching device box body 3, and be used for switching device box body 3 is fixed on the axletree as being fixed on the anchor fitting 4 at the semiaxis side rear portion between tire and the spring plate, top in switching device box body 3 is equipped with friction lining 5, be connected with the lead 6 that is connected with alarm controller 2 on this friction lining 5, switching device box body 3 inside are equipped with before an anchor shaft 7, the friction rocking arm 8 of back swing, when friction rocking arm 8 is in plumbness, its top and friction lining 5 are separated, when wiping rocking arm 8 is in heeling condition, its top contacts with friction lining 5, friction rocking arm 8 its latter halfs are passed the rectangle slotted eye 9 that is positioned at switching device box body 3 bottoms and are stretched out downwards from switching device box body 3, between the wall of friction rocking arm 8 and switching device box body 3, be connected with pull back spring 10, the lower end of friction rocking arm 8 is equipped with the spring 11 that contacts to earth, metal piece 12 is fixedly mounted on the wheel steel ring as bent bolt, between friction rocking arm 8 and metal piece 12, be equipped with and touch steel ring spring 13, the one end is connected with friction rocking arm 8, its other end and metal piece 12 are at a distance of gapped, anchor fitting 4 includes the fixed dam 14 that is fixedly connected with switching device box body 3, with the restraint zone 16 that is connected with fixed dam 14 by attaching parts 15; As shown in Figure 2, alarm controller 2 described in the utility model includes control desk 17 and the electric switch of fixing on it 18, buzzer phone 19, electric switch 18 and buzzer phone 19 are connected with the lead 6 of the friction lining 5 of power lead 20 and alarm switch device 1 respectively, electric switch 18 is equipped with driving lever 21, between electric switch 18 and the buzzer phone 19 wire fuse 22 is installed.

Its working process of annunciator described in the utility model is

When tire deflation, distance between vehicle and the road surface shortens, make under normal circumstances and contact with the road surface with the discontiguous spring 11 that contacts to earth in road surface, to overtake the time, because the effect of friction force, the spring 11 that contacts to earth is swung backward at vehicle, thereby driving friction rocking arm 8 rotates around anchor shaft 7, friction rocking arm 8 is contacted with friction lining 5, circuit turn-on as a result, the buzzer phone 19 of alarm controller 2 sends alarm sound immediately; With should tire producing when waving fault, touch steel ring spring 13 and collide with tyre rim or with position metal piece 12 thereon, rotate thereby drive friction rocking arm 8, its upper end is contacted with friction lining 5, circuit turn-on as a result, buzzer phone 19 sends alarm sound; When vehicle travels on rugged road surface, in order to prevent wrong report, can open switch by driving lever 21, cut off the electricity supply, annunciator is temporarily quit work.

Annunciator described in the utility model can be timely, exactly the fault of vehicle tyre reported to the police, and it is simple in structure, and manufacturing and easy to use, with low cost can widely be used in vehicle.
