Abstract
The utility model relates to a tire low pressure alarm which relates to a device which can automatically raise the alarm when air pressure in a tire is lower than normal air pressure. The tire low pressure alarm is composed of an air pressure induction device A, an electronic alarm B and a power source C, wherein the air pressure induction device comprises a casing (2), an air pressure sensing head (1), an electric pole slice (3) and a spiral compression spring (5), and the lower end of the air pressure sensing head (1) is arranged in a through hole (2-1) of the casing (2); the electric pole slice (3) fixed in the casing (2) is fixedly connected with the lower end of the air pressure sensing head (1), and the spiral compression spring (5) is butted with the lower side of the electric pole slice (3). An electric pole (2-2) is arranged around the through hole (2-1), and the electric pole slice (3), the power source C, the electronic alarm B and the electric pole (2-2) are orderly connected in series. The tire low pressure alarm not only can tell whether the air pressure in the tire is lower than the normal air pressure, but also can send out an alarming signal at the time of low air pressure, so the tire low pressure alarm guarantees driving safety and reduces the occurrence of unexpected accidents.
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, just can guarantee automotive safety and normal operation, but people are difficult to judge whether the pressure in the tire conforms to requirement.At this moment automobile also can serious accident will not occur as not taking urgent measure because of some cause specifics cause tire flat, but also not measure the pressure in the tire at present, and send the device of alerting signal when long-distance operation.
Summary of the invention: the utility model is a kind of tire low pressure alarm of design, and whether the pressure that this annunciator should be able to be judged in the motor tire is lower than standard pressure, and can send the signal of warning.The 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 include the housing 2 that is fixedly connected on the wheel steel ring D, with the contacted air pressure sensing head 1 in outside, electrode slice 3, the spiral compression spring 5 of inner tube E, the lower end of air pressure sensing head 1 is arranged in the through hole 2-1 above the housing 2, be arranged on the lower end that housing 2 interior electrode slices 3 are fixedly connected on air pressure sensing head 1, spiral compression spring 5 withstand on electrode slice 3 below, periphery at through hole 2-1 is provided with electrode 2-2, and electrode slice 3, power supply C, electronic alarm B and electrode 2-2 are connected in series in order.When the pressure of inner tube E is standard value, can promote air pressure sensing head 1 and move down, this moment, electrode slice 3 was a contactless state with electrode 2-2; When the pressure of inner tube E reduces, under the elastic force effect of spiral compression spring 5, move on the air pressure sensing head 1, this moment, electrode slice 3 contacted with electrode 2-2, the circuit series of being made up of electrode slice 3, power supply C, electronic alarm B and electrode 2-2 is in closure state, and electronic alarm B sends alerting signal.This device can not only judge whether the pressure in the motor tire is lower than standard pressure, and can also send alerting signal when low pressure, has guaranteed traffic safety, has reduced the generation of contingency.
