Abstract
The utility model provides an automatic alarm of auto vehicle protective tyre, relating to a monitoring device for air pressure of motor vehicle tyre. The utility model is characterized in that a fixing frame plate is installed on a sleeve at the inner side of the automobile tyre through a fixing frame; a movable plate which can rotate surrounding a pivot is arranged on the fixing frame plate; a movable contact is arranged on the movable plate, and a fixed contact is arranged on the fixing frame plate; the rotation of the movable plate controls engaging and disengaging of the movable and fixed contacts; the lower end of the movable plate is provided with a contact lever. When the air pressure of the vehicle tyre is insufficient, the contact lever contacts ground to drive the movable plate to rotate, making the movable and static contacts closed to switch on a sound circuit of a vehicle horn which can send out alarming. In such a way, the utility model can make a driver find the insufficient air pressure of the vehicle tyre in time, and thus, accidents of tyre pricking, tyre dropping off, etc. caused by the insufficient air pressure of the vehicle tyre are avoided.
Description
The utility model relates to a kind of automobile tyre monitor device.
The especially long-distance loading transport trolley of self-propelled vehicle damages because of tire valve sometimes, and tire is pricked reason such as bad and caused tire pressure too small, pricks the phenomenon that useless and wheel hub rolls bad highway if tire will appear in untimely discovery and solving, and causes the certain economic loss.
The purpose of this utility model is to provide a kind of automobile tyre monitor device, avoids the tire that causes because of tire pressure is too small to prick the phenomenon that useless and wheel hub rolls bad highway.
The technical solution of the utility model is as follows:
Comprise a fixedly frame plate that has a fixed mount, by fulcrum be fixed on the fixing frame plate and can around portable plate that fulcrum rotates, connect the portable plate upper end and fixedly frame plate return spring, be located at the feeler lever of portable plate lower end and be provided with the moving contact on the portable plate and be located at fixed contact on the fixing frame plate etc., portable plate rotates, can control the clutch of moving contact and fixed contact, moving contact and break back contact are connected in the horn of motor vehicle sound circuit.
Fixed mount of the present utility model is sleeved on the axle sleeve of motor tire inboard, adjust feeler lever, make under the feeler lever 3-5 centimetre on end distance ground, work as low tyre like this, contacting to earth in the feeler lever lower end, drives portable plate and rotate, and makes moving contact and fixed contact closure, horn trumpet sends the sound, plays the monitoring effect.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model installation site scheme drawing.
Accompanying drawing 3 is the utility model feeler lever scheme drawing that contacts to earth.
Accompanying drawing 4 is the utility model feeler lever action scheme drawing that contacts to earth.
As shown in drawings, the utility model fixedly frame plate 3 be fixed on the wheel inboard by the fixed mount 1 that is sleeved on the wheel axle sleeve 2.A side of portable plate 6 is provided with locating dowel pin 9 between return spring 10 and fulcrum 5, and under the normal situation of air pressure of automobile tire, portable plate 6 is stuck in a side of locating dowel pin 9 under the effect of return spring 10, and this moment, moving contact 8 separated with break back contact 4, as shown in Figure 1.Portable plate 6 can adopt iron plate making, and feeler lever 7 adopts iron wire to make.Break back contact 4 connects in the horn trumpet sound circuit by lead 11.When the air pressure of automobile tire deficiency is contacted to earth feeler lever 7, portable plate 6 rotates around fulcrum 5, moving contact 8 and break back contact 4 closures, shown in accompanying drawing 3,4, connect the loudspeaker sound circuit this moment, horn trumpet sends whistling, and chaufeur is in time found, avoids causing therefrom accidents such as bundle tire and tire come off.
The utility model is suitable for using on even running road surface, and when travelling on scraggly road surface as automobile, chaufeur can intermittently be rung power-off to prevent horn trumpet.
