Abstract
The utility model discloses a safety alarm device for detecting pressure of tyres of automobiles, which comprises a signal emitting device and a signal receiving device, wherein, the signal emitting device is installed on a wheel rim of the automobile; the signal receiving device which is matched with the signal emitting device is fixed on a body of the automobile. The pressure in the tyer, which is collected by the signal emitting device, is provided for the receiving device in the electrical signal mode. The signal received by the receiving device is led to a driver. The driver knows the condition of the pressure in the tyre in the process of normally running in real time. Consequently, the driver can accurately judge that the automobile runs continuously or stops to be maintained.
Description
The utility model discloses a kind of safety alarm device that is used to detect air pressure of automobile tire.
Recently, along with popularizing of automobile, the get on the car continuous increase of flow of highway, traffic accident also increases thereupon, the serious person and property damage have been caused, according to investigations in the traffic accident, have 50%～60% vehicle at least, particularly on express highway, be far longer than this numeral owing to tyre explosion causes.Occurring blows out mainly is because chaufeur can't carry out actv. to the air pressure in the motor tire in driving procedure detect, and can only lean on experience, sensation, so just occurs unexpected unavoidably.
The purpose of this utility model provides a kind of can effectively the detection and to its detection alarm device that forecasts air pressure of automobile tire.
For achieving the above object, the technical solution adopted in the utility model is: the automatic detection alarm device of a kind of air pressure of automobile tire, it comprises the signal transmitting and receiving device, it is characterized in that: the contact switch A, the B that are provided with on sender unit and the cylinder body link to each other, contact switch A, B are provided with piston between the two, be provided with a stage clip between piston and the cylinder bottom, the another side of piston is connected with tracheae, and tracheae is communicated with the valve inside of tire.
In technique scheme, sender unit is installed on the automotive hub, the receiving device that is mated use is fixed on the car body, air pressure in the tire that sender unit collects will provide to receiving device with the form of electric signal, receiving device is guided the signal that receives into chaufeur, allow chaufeur in the normal driving process, learn barometric information in the tire in real time, thereby allow the chaufeur can be whether continuing to drive or parking maintenance is made right judgement.
Description of drawings
Fig. 1,2, the 3rd, structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, the utility model comprises signal transmitting and receiving device (not drawing among the figure), transmitting and receiving device can with reference in the prior art about infrared and receiving device technology, the contact switch A that is provided with on sender unit and the cylinder body 10, B links to each other, contact switch A, B is provided with piston 20 between the two, be provided with a stage clip 40 between piston 20 and the cylinder bottom, the another side of piston 20 is connected with tracheae 30, tracheae 30 is communicated with the valve inside of tire, when tire pressure rises, piston 20 is subjected to pressure that tire pressure rises and to the side shifting at contact switch B place, as shown in Figure 3, when maxim that air pressure is allowed during near the tire normal operation, piston 20 moves and touches contact switch B, therefore the sender unit maximum value signal that sends that air pressure arrives or allow during near the tire normal operation is delivered on the indicator lamp in the operator's compartment by receiving device, and indicator lamp can be arranged on the gauge panel.
When tire pressure reduces, piston 20 is subjected to the force action of pressure that tire pressure rises and spring 40 and to the side shifting at contact switch A place, as shown in Figure 1, when minimum value that air pressure is allowed during near the tire normal operation, piston 20 moves and touches contact switch A, therefore the sender unit minimum value signal that sends that air pressure arrives or allow during near the tire normal operation is delivered on the indicator lamp in the operator's compartment by receiving device, and indicator lamp can be arranged on the gauge panel.
During normal operation, piston 20 is between contact switch A, B, as shown in Figure 2.
According to the indicator lamp content displayed, driving can be understood the pressure condition of motor tire in real time, so that in time handle decision, so that guarantee traffic safety.
Move in certain scope for satisfying piston 20, tracheae 30 can be made a flexible pipe, perhaps tracheae 30 is made the version of stretching place formula rigid pipe.
