Abstract
The utility model relates to a low pressure alarm device for tyres. The utility model is characterized in that an air pressure sensor (1) is connected with a wireless transmitting device (3) through a control conducting wire (2); the wireless transmitting device (3) is connected with an alarm receiver (4) through a wireless signal; an air nozzle of the tyre is provided with the air pressure sensor (1) which is provided with a fixed contact screw bolt (9) and a movable contact nut (8); the wireless transmitting device (3) which is controlled by the air pressure sensor (1) is installed on the central position out of a wheel shaft; the wireless alarm receiver (4) is installed in a driving room. The utility model has the function that the utility model can monitor that whether the value of the air pressure of the tyre is lower than the rated value.
Description
The utility model belongs to a kind of safety running of motor-vehicle annunciator.
Self-propelled vehicle under steam, often since rear tyre leak gas slowly and be difficult for to find, cause rubber-tyred roller bad, scrap traffic accident and personal injury take place even; Owing to there is not this class warning device, this kind phenomenon happens occasionally on the current mobility car.
The goal of the invention of the utility model flat tire alarm device provide a kind of when automobile tyre because of the Rapid Alarm device of gas leakage during deficency slowly.
The goal of the invention of the utility model flat tire alarm device realizes by following technical measures: baroceptor is connected with wireless launcher by pilot, wireless launcher and receptor are got in touch by wireless signal, the base part shell of baroceptor in a tubular form, length is 20 to 120 millimeters, diameter is 6 to 40 millimeters, the bolt that has protrusion and air bleeder and double as fixed contact is with the cartridge type pressure pad, rubber diaphragm, guide rod, armature contact and plain cushion are fixed in the shell, spring perch and spring housing are contained on the guide rod, and an end of shell is installed bench insulator, and action adjustment of inflation pressure bolt is spun on the bench insulator and with spring perch and contacts.Captive nut is fixed on armature contact pig-tail wire terminal and flat gasket on the bench insulator.The pressure sensor that has the contact is installed on the vapour lock of tire, and the wireless launcher of the sensor that is stressed control is installed on the outer center of wheel shaft, and the radio alarming receptor is installed in the operator's compartment.
Below in conjunction with drawings and Examples this use novel tire deficency warning device is further specified:
Fig. 1 is the scheme drawing of the utility model deficency warning device
Fig. 2 is the cut-away view of the utility model deficency warning device baroceptor
Fig. 3 is the right elevation of Fig. 2
Embodiment 1: baroceptor 1 is connected with wireless launcher 3 by pilot 2, wireless launcher 3 and alarm receiver 4 are got in touch by wireless signal, the base part shell 18 of baroceptor 1 in a tubular form, length is 20 to 120 millimeters, diameter is 6 to 40 millimeters, bolt 9 has protrusion and air bleeder and double as fixed contact, bolt 9 is with cartridge type pressure pad 10, rubber diaphragm 7, guide rod 6, armature contact nut 8 and plain cushion 11 are fixed in the shell 18, and spring perch 12 and spring 5 are sleeved on the guide rod 6, one end of shell 18 is installed bench insulator 17, and action adjustment of inflation pressure bolt 15 is spun on the bench insulator 17 and with spring perch 12 and contacts.Captive nut 16 is with armature contact nut 8, and pig-tail wire terminal 14 and flat gasket 13 are fixed on the bench insulator 17.The pressure sensor 1 that has fixed contact bolt 9 and armature contact nut 8 is installed on the vapour lock of tire, and the wireless launcher 3 of sensor 1 control that is stressed is installed on the outer center of wheel shaft, and radio alarming receptor 4 is installed in the operator's compartment.Spring 5 and adjustable bolt 15 are used to adjust armature contact nut 8 action atmospheric pressure values.One end of shell 18 has the negative thread that is connected with cranked tire valve and the projection of unseat the valve core valve, and the other end of shell 18 and baroceptor 1 has the pig-tail wire terminal 14 that is connected with armature contact nut 8, and pig-tail wire terminal 14 is connected with lead 2.Under normal conditions, spring 5 tension force in tire internal gas pressure and the baroceptor 1 balance each other, and armature contact nut 8 is failure to actuate at this moment.When situations such as wheel puncture, damage occur makes the tire internal gas pressure be lower than rated value, the armature contact nut 8 of baroceptor 1 moves to fixed contact bolt 9 directions under the effect of spring 5 tension force, until the contact conducting, thereby make wireless launcher 3 work send alerting signal, send sound and light alarm behind alarm receiver 4 received signals.Make pig-tail wire son 14 close airtight after the installation with shell 18 insulation and assurance rubber diaphragm 7.The utility model flat tire alarm device also has the function for monitoring that tire pressure is lower than rated value.
The advantage of the utility model flat tire alarm device is: simple in structure, volume is small and exquisite, Reliable in action, the record of reporting to the police be quick, easy for installation, with low cost, be easy to promote.
