Abstract
The utility model discloses a tyre air pressure alarming device which relates to a device which can automatically alarm when the air pressure in the vehicle tyre is lower than the normal air pressure. An air pressure induction device A of the tyre air pressure alarming device comprises a casing (1), an air pressure sensing head (2) arranged in a hole (1-1) of the casing (1), a spring (3) which can lift the air pressure sensing head (2) to enable the top part of the air pressure sensing head (2) to extend to the external side of the hole (1-1), a contact point (4) and an electric conduction element (10) which contacts the contact point (4) when the air pressure in the tyre is reduced and the air pressure sensing head (2) moves upwards. The contact point (4) is fixed to the side wall of the air pressure sensing head (2), and the electric conduction element (10) is fixed to the inner wall of the hole (1-1); an electronic alarm B and a power supply C form a series circuit, one end of the circuit is connected with the electric conduction element (10) through conducting wires, and the other end of the circuit is connected with the contact point (4) through conducting wires. The tyre air pressure alarming device not only can judge whether the air pressure in the vehicle tyre is lower than the normal air pressure, but also can send out early alarming and alarming signals in low air pressure.
Description
Technical field: device that can auto alarm when the utility model relates to a kind of pressure in motor tire and is lower than normal barometric pressure.
Background technology: need enough air pressure in the motor tire and could guarantee automotive safety and normal operation, but people are difficult to judge whether the pressure in the tire conforms to requirement.Whether automobile also can at this moment serious accident will not occur as not taking urgent measure because of some cause specifics cause tire flat, but also not measuring the tire internal gas pressure at present is lower than standard pressure, and sends the device of alerting signal when long-distance operation.
The utility model content: the utility model designs a kind of tire pressure alarm, and whether the pressure that this annunciator should be able to be judged in the motor tire is lower than standard pressure.Tire pressure alarm of the present utility model is made up of air pressure induction installation A, the electronic alarm B that can produce alerting signal and power supply C; Air pressure induction installation A comprises housing 1, be arranged on air pressure sensing head 2 among the hole 1-1 of housing 1, with air pressure sensing head 2 upwards jack-up make it spring 3 that the top extends hole 1-1 outside, contact 4, when the tire internal gas pressure reduces air pressure sensing head 2 and moves up and the 4 contacted conducting elements 10 of contact, contact 4 is fixed on the sidewall of air pressure sensing head 2, and conducting element 10 is fixed on the inwall of hole 1-1; Electronic alarm B and power supply C form circuit series, and an end of this circuit is connected with conducting element 10 by lead, and the other end of this circuit is connected with contact 4 by lead.During use this tire pressure alarm is installed in the interior annular groove of tyre rim D, air pressure sensing head 2 moves up and down along with the lifting of tire internal gas pressure, and contact 4 just contacted with conducting element 10 when pressure was low, made annunciator send signal.This device can not only judge whether the pressure in the motor tire is lower than standard pressure, and can also send when low pressure and give alert and alerting signal.Use this device can guarantee traffic safety, reduce the generation of contingency.
Description of drawings: Fig. 1 is the structural representation of the specific embodiment one, Fig. 2 is the circuit diagram of the specific embodiment one, Fig. 3 is the structural representation of the specific embodiment two, and Fig. 4 is the structural representation of the specific embodiment three, and Fig. 5 is the circuit diagram of the specific embodiment three.
The specific embodiment one: consult Fig. 1, Fig. 2, the tire pressure alarm of present embodiment is made up of air pressure induction installation A, the electronic alarm B that can produce alerting signal and power supply C; Air pressure induction installation A comprises housing 1, be arranged on air pressure sensing head 2 among the hole 1-1 of housing 1, with air pressure sensing head 2 upwards jack-up make it spring 3 that the top extends hole 1-1 outside, contact 4 and by giving the conducting element 10 that alert contact 5 and alarm actuating contact 6 are formed, contact 4 is fixed on the sidewall of air pressure sensing head 2, alarm actuating contact 6 and give two diverse locations up and down that alert contact 5 is separately fixed at hole 1-1 inwall; Electronic alarm B and power supply C form circuit series, an end of this circuit by two leads respectively with give alert contact 5 and be connected with alarm actuating contact 6, the other end of this circuit is connected with contact 4 by a lead.Below spring 3, also be provided with adjusting pad 7, adjusting pad 7 and hole 1-1 screw thread fit, adjusting pad 7 can be adjusted the pressure of 3 pairs of air pressure sensing heads 2 of spring.Also be provided with battery compartment 1-2 and electronics storehouse 1-3 in housing 1, power supply C is arranged in the battery compartment 1-2, and electronic alarm B is arranged in the 1-3 of electronics storehouse.The upper surface of the outside face of housing 1 and air pressure sensing head 2 is spherical, can avoid pressing against bad inner tube like this.Below housing 1, also be provided with bottom 8, the bottom surface 8-1 of bottom 8 be with tyre rim D in the arcwall face that matches of annular groove.Outside at this annunciator also is surrounded by rubber film 9.When the pressure in the tire is standard value, can move down towards the air pressure sensing head 2 of inside tires, with spring 3 compressions, this moment contact 4 with alarm actuating contact 6 with give alert contact 5 and all be not connected; When the pressure in the tire reduced, air pressure sensing head 2 moved up, and this moment, contact 4 contacted with giving alert contact 5, and closing of circuit sends electronic alarm B and gives alert signal, remind chaufeur to overhaul or inflate; When the hypotony in the tire, air pressure sensing head 2 amounts of moving up are bigger, and this moment, contact 4 meetings contact with alarm actuating contact 6, and electronic alarm B just sends alerting signal, and alerting drivers takes urgent measure.
The specific embodiment two: consult Fig. 3, what present embodiment and the specific embodiment one were different is that electronic alarm B is an electromagnetic wave transmitter, also has additional an electromagnetic receiver G in the indoor instrument D of vehicle drive.Other composition is identical with the specific embodiment one with annexation.
