The utility model content
The purpose of this utility model is to provide a kind of can adapt to various weather conditions and various temperature condition, is applicable to various road conditions, and water-tight is simple in structure, is easy to install the annunciator that the air pressure of automobile tire of being convenient to safeguard changes.
For achieving the above object, the utility model air pressure of automobile tire changes annunciator, comprise pressure inductor, projector and the receptor that is installed in the operator's compartment, described projector is installed on the wheel rim, described pressure inductor is installed on the outer ring of wheel rim or semiaxis covers, described pressure inductor comprises that the top is provided with the metal housing and the following insulating mat that is installed in the metal housing bottom of through hole, between the top of metal housing and following insulating mat, metal contact is housed respectively from top to bottom, last insulating mat and spring, the top of described metal contact is with insulation sleeve and stretches out from the through hole of metal housing, picks out a lead respectively from metal contact and metal housing and is connected with projector.
The utility model air pressure of automobile tire changes annunciator, wherein, between the top of described metal contact and metal housing, is set with the metal hairspring on metal contact.
The utility model air pressure of automobile tire changes annunciator, wherein, described pressure inductor also comprises the bimetallic plate that is arranged on down on the insulating mat, the lead of the moving contact of bimetallic plate and the lead of described metal contact link together, and the lead of its break back contact and the lead of metal housing link together.
The utility model air pressure of automobile tire changes annunciator, its pressure inductor is directly installed on the wheel rim outer ring, under the gentle tender feeling condition of various weather, all can normally use, stifled phenomenon can not appear freezing, thereby can accurately report to the police, because structure is very simple, installation and maintenance are all very convenient, when gas leakage takes place motor tire, when perhaps tire pressure raises, pressure inductor can be responded to the variation of tire pressure of automobile tire at any time, signal is delivered to receptor by projector, thereby can report to the police, remind the driver in time changing of tire, try to avert accidents.
Description of drawings
Fig. 1 changes the scheme drawing of first embodiment of annunciator for the utility model air pressure of automobile tire;
Fig. 2 changes the scheme drawing of second embodiment of annunciator for the utility model air pressure of automobile tire;
Fig. 3 changes the scheme of installation of annunciator for the utility model air pressure of automobile tire.
The specific embodiment
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Figure 1 shows that the utility model air pressure of automobile tire changes the scheme drawing of first embodiment of annunciator, comprise the pressure inductor 10 that is installed on wheel rim 9 outer rings, be installed in the projector on the wheel rim 9 and be installed in the interior receptor of operator's compartment, projector also can be installed in semiaxis and cover, described pressure inductor 10 comprises that the top is provided with the metal housing 1 of through hole, be installed in the following insulating mat 5 of metal housing 1 bottom, spring 4 is fixed on down on the insulating mat 5, be provided with insulating mat 3 at the top of spring 4, the bottom of metal contact 2 is inserted and is gone up in the insulating mat 3, the top of metal contact 2 is with insulation sleeve 13 and stretches out from the through hole at metal housing 1 top, picking out a lead respectively from metal contact 2 and metal housing 1 is connected with wireless launcher, between the top of described metallic contact 2 and metal housing 1, the top of metallic contact 2 is set with metal hairspring 12.
During installation, as shown in Figure 3, on the lift 8 between the wheel rim 9 and the inner tube of a tyre 7, be positioned at the center line of wheel rim, apart from valve 7 centimeters, lift 8 is opened the hole that a diameter with pressure inductor 10 adapts, pressure inductor 10 is put into wherein, metal contact 2 is towards the inner tube of a tyre 7, both sides at lift 8 cover pressure inductor 10 with two blocks of rubber as pad, and an end of rubber is bonded on the lift, and lead is drawn from valve 11.Be fixed on wireless launcher on the wheel rim or semiaxis covers, the lead that pressure inductor 10 is drawn is connected on the wireless launcher.Wireless receiver is installed in the operator's compartment, is wired on the storage battery, and working voltage is the power supply of 12V.
During use, with the tire sufficient gas, the pressure on the metal contact 2 is during greater than 1kg power, spring 4 compressions, metal contact 2 disconnects with metal housing 1, at this moment, circuit disconnects not conducting, and when the tire flat tire pressure was not enough, pressure suffered on the metal contact 2 was less than 1kg power, spring 4 resets, and metal contact 2 is joined with metal housing 1, at this moment, circuit is connected, send signal to wireless receiver by wireless launcher, carry out sound and light alarm in operator's compartment, the prompting driver in time takes measures.
Figure 2 shows that the utility model air pressure of automobile tire changes the scheme drawing of second embodiment of annunciator, in pressure inductor except described spring of the foregoing description and metal contact device are installed, be arranged on down the bimetallic plate 14 on the insulating mat in addition, the lead of the moving contact of bimetallic plate 14 and the lead of described metal contact link together, the lead of its break back contact and the lead of metal housing link together, and lead is connected on the wireless launcher.
Mounting means is identical with first embodiment, during use, when the vehicle length time, overload was travelled, the tire heating, the tire internal gas pressure raises, when temperature reaches 100 ℃, bi-metal plate deformed and switch on, at this moment, send signal to wireless receiver, in operator's compartment, carry out sound and light alarm by wireless launcher, the prompting driver in time takes measures, during normal temperature, circuit is disconnected, but driver's cruising.
