Abstract
The utility model relates to a multiway miniature and wireless tyre air shortage alarm, which is characterized in comprising a miniature mechanical pressure switch, a miniature radio emitter with a plurality of signs and a multiway wireless receiver. The miniature mechanical pressure switch is integrated with the miniature radio emitter. The multiway wireless receiver can receive the signal from the miniature radio emitter. The utility model can monitor pressure condition of each tyre at the same time without consuming existing pressure of the tyre. Therefore, the utility model can be used in tyres of different specifications and pressure scopes. The wireless receiver can alarm and accurately display relevant position of the tyre where air is used out so as to favor reparation quickly. The multiway wireless receiver and the miniature radio emitter with a plurality of signs can cooperate with other switch or sensor. The utility model can be generalized to and used in other fields.
Description
Technical field
The utility model relates to the automobile warning device, specifically multi-channel tire deflation micro radio annunciator.
Background technology
Motor tire is that suffered ground-surface impacts and the important device of vibrations when supporting automobile total weight and absorption and buffering and travelling, in the process of moving, because a certain low tyre can cause brake to depart from the cruising route; Particularly autotruck can cause other tyre break, and major accident takes place; Perhaps because of low tyre, the centre of gravity of vehicle skew makes automobile produce heel and toe wear, the service life of economization automobile and parts.Understanding each tire pressure situation rapidly is even more important with corresponding particular location.Existing tire deflation alarm has plenty of and costs an arm and a leg, installs inconvenience; Have plenty of and utilize the residual gas of tire to send chimes of doom by it, make the interior gas of doughnut fewer and feweri like this, if untimely processing, consequence is more dangerous.
Summary of the invention
The purpose of this utility model provides the multi-channel tire deflation micro radio annunciator that a kind of sensitivity is reliable, alarm range is wide, volume is little, cost is low.
The technical solution of the utility model is: multi-channel tire deflation micro radio annunciator by the micromachine pressure switch, have a plurality of have oneself the sign mini radio projector and multichannel radio receptor constitute; Micromachine pressure switch and mini radio projector are combined as a whole, and the multichannel radio receptor receives the signal from the mini radio projector.
The micromachine pressure switch constitutes by connecting valve joint and rear casing; Pilot body and seal ring are installed in the joint, pressure guide hole and pressure chamber are arranged in the pilot body, there are pad and pilot film in pilot body back, the valve joint is connected with pressure switch, valve joint and pressure switch have seal ring, spacing piston is arranged in the pressure switch, be with spring above the spacing piston, the mini radio projector is installed in the rear casing.
Mini radio projector and multichannel radio receptor all are made of micro controller system, the micro controller system coding techniques can make each mini radio projector that the sign (mini radio projector micro controller system model is PP2260-R4F) of oneself is arranged, and the micro controller system of radio receiver (the module model is LM358) is recognition coding accurately.The micromachine pressure switch construction is simple, and is easy to make, and volume is little, in light weight, and cost is low, long service life, and it is convenient to change, and limit chamber wherein and spacing piston can guarantee not wash out when pressure is excessive projector and no leak tire gas.
Multi-channel tire deflation micro radio annunciator of the present utility model can be monitored the pressure condition of each tire simultaneously, and not loss has tire pressure now, pressure monitoring scope: 0.15～1.3MPA (positive and negative 0.05MPA) is applicable to different types of tyre and different pressures scope.Radio receiver is positioned at operator's compartment, to there be the mini radio projector that oneself identifies to be installed in proper order on the corresponding tire, when any one tire pressure less than regulation during air pressure, mini radio projector emission alerting signal, radio receiver will be reported to the police and the accurately relevant position of demonstration deficency tire, cheaply maintenance rapidly.The multichannel radio receptor and have oneself the sign the mini radio projector can also cooperate other switch, sensor to promote the use of other field.Also be specially adapted to danger, poisonous and harmful, people and can not be directly adjacent to the place of observation, and some need follow the tracks of the object with radio detection and warning.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, but is not limited to shown in the accompanying drawing.
Embodiment: as shown in the figure, multi-channel tire deflation micro radio annunciator of the present utility model by the micromachine pressure switch, have a plurality of have oneself the sign mini radio projector multichannel radio receptor constitute; Micromachine pressure switch and mini radio projector are combined as a whole, and the multichannel radio receptor receives the signal from the mini radio projector.
The micromachine pressure switch constitutes by connecting valve joint 10 and rear casing 1; Pilot body 11 and seal ring 9 are installed in the joint 10, pressure guide hole 13 and pressure chamber 12 are arranged in the pilot body 11, there are pad 8 and pilot film 7 in pilot body 11 back, valve joint 10 is threaded with pressure switch 2, valve joint 10 has seal ring 4 with pressure switch 2, spacing piston 5 is arranged in the pressure switch 2, and being with spring 3,6 above the spacing piston 5 is limit chamber.Joint 10 is threaded with pilot body 11, and pressure switch 2 is threaded with rear casing 1.Mini radio projector 14 is installed in the rear casing 1.
Microswitch of the present utility model is connected joint 10 in use with the cranked tire valve joint, pilot body 11 backs down the valve valve, and tire gas is imported pressure chamber 12 by pressure guide hole 13, and seal ring 9 and seal ring 4 prevent gas leak, guarantee the tire normal operation.Pilot film 7 is derived tire pressure, passes to spacing piston 5.At pressure just often, spacing piston 5 moves forward by limit chamber 6, closes the power supply of mini radio projector 14, sends the radio signal that oneself identifies.Radio receiver will be reported to the police and the accurate relevant position that shows the deficency tire like this, cheap maintenance rapidly, and do not consume the existing pressure of tire.
During use, will there be the mini radio projector of year oneself sign to be connected also fastening with corresponding cranked tire valve; The source switch of opening the multichannel radio receptor gets final product.
