Abstract
The utility model relates to a tyre air pressure alarm device, which comprises a pressure sensor and an alarm which are connected through a circuit bridge, wherein, the pressure sensor is installed on the tyre of vehicles; the circuit bridge comprises a bearing which is installed on a half shaft of the vehicle; an inner ring and an outer ring of the bearing are respectively insulated with a vehicle body; a static ring of the bearing is connected with the alarm through a conducting wire; a movable ring of the bearing is connected with the pressure sensor through the conducting wire. The utility model can make a driver in a driving room know the inflating condition of the tyre of the vehicle. When the gas in the tyre is leaked suddenly in the course of running, the driver can discover the condition in time. The utility model can bring convenience for the driver and simultaneously can avoid causing economic loss or serious traffic accidents.
Description
The utility model is a kind of warning device, particularly a kind of can the monitoring equipment motor-car automobile tyre air pressure alarm device that changes of tire pressure in the process of moving.
Self-propelled vehicle is in operational process, tire can be because a variety of causes generation deficency phenomenon, because the energy of chaufeur concentrates on the driving and the ground-surface of vehicle and observes, generally be difficult to find the pressure variation of tire, so often cause tire because of deficency reduction of service life, can cause traffic accident when serious, consequence is hardly imaginable.A kind of warning device of warning pressure variation by wireless transmission signal is arranged now, because of making it, shortcomings such as it involves great expense can not get popularizing, so the alarming device of tire deflation all is not set above the up to the present various automobiles, prevents because phenomenons such as wear on tyres that tire deflation caused and traffic accident can not obtain actv..
The purpose of this utility model provides a kind of later-model alarm device for tyre pressure, and it can overcome existing shortcoming in the prior art, and is simple in structure, cost is low, is suitable for various self-propelled vehiclees and installs.
The purpose of this utility model is achieved in that it comprises the pressure sensor that is installed on the wheel and is installed on the interior annunciator of operator's compartment, connect by the circuit bridging between them, the sensing head that it is characterized in that pressure sensor contacts with inner tube of a tyre outside face, the circuit bridge comprises a bearing that is installed on the automobile axle shaft, bearing insulate mutually with car body, by lead with the Jing Quan of bearing be connected with annunciator, the bearing moving-coil is connected with pressure sensor.
Pressure sensor of the present utility model is fixedly mounted on the tire of automobile, sensing head withstands on the outside face of the inner tube of a tyre, when the unsaturated vapor in the motor tire, the inner tube of a tyre is to the pressure change of sensing head, send electric signal, by the alert loop of circuit bridge joint circular, annunciator sends sound, light is reported to the police, the tire unsaturated vapor of prompting driver and passenger automobile needs inflation.
The utility model carries out dynamic and static cleverly conversion by the circuit bridge, the pressure sensor annunciator interior with being installed on operator's compartment that is installed on the tire place is connected, can make chaufeur in operator's compartment, know the unexpected variation of air pressure of automobile tire at any time, provide very big help to chaufeur, prolong the service life of tire, avoided the traffic accident that causes because of the unexpected flat tire of tire to a certain extent.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
Fig. 1 is an integral installation scheme drawing of the present utility model.
Fig. 2 is a structural representation of carrying the bridge of circuit shown in 1.
Fig. 3 is the structural representation of pressure sensor shown in Fig. 1.
As shown in Figure 2, utilized a bearing 8 on the semiaxis shell in the circuit bridge, in bearing, insulation sleeve 9 and 10 are equipped with in the outer ring, itself and car body are insulated, the protective cover 11 that prevents dust and play insulating effect simultaneously is housed in the side of bearing simultaneously, with reference to shown in Figure 3, the shell 12 of pressure sensor is an insulator, two ends are threaded, one end is equipped with adjustable bolt (binding post) 13, the other end is equipped with installation sleeve 14, and spring 15 is equipped with in the centre, is fitted with sensing head 16 in installation sleeve, the footpath portion of sensing head has insulating barrier 17, overall installation as shown in Figure 1, pressure sensor 1 is fixedly mounted on by installation sleeve on the steel ring 2 of motor tire assembly, sensing head contacts with the outside face of inner tube 18.Circuit bridge 3 is installed on the shell 4 of automobile axle shaft 5,6 is combined aural and visual alarm among the figure, the 7th, and the annunciator power supply is connected by lead between them, pressure sensor is connected with bearing moving-coil (outer ring) in the circuit bridge, and annunciator is connected with Jing Quan (inner ring) in the pressure sensor.If with the pressure sensor micro-miniaturisation, the valve of itself and tire can be mounted to one.
