Abstract
A tire pressure safety warning indicator on wheel tire includes an air chuck which can be combined on a wheel tire and an air chuck cap combined on the air chuck. When the tire is pumped with air, the air can enter into an air chamber in the air chuck at the same time, so that the air pressure in the air chamber and that in the tire is kept balanced. A switch is communicated with a pressure output of the pressure keeping assembly component, and cut off when the air pressure of the air chamber and that of the tire is kept balanced; when the tire runs flat and the tire pressure is lower than the air pressure in the air chamber, the air in the air chamber can push the switch with the help of a pressure output end at one end of the air chamber to contact the switch to form a communicated circuit with a battery set and a warning device in the air chuck cap, to give the warning signal of insufficient tire pressure and remind the driver to supplement tire pressure.
Description
Technical field
The present invention relates to a kind of safety alarming device, during gaseous tension lack of equilibrium in particularly a kind of air chamber and tire that passes through in the valve, the triggering alarming device is with the vehicle tyre pressure safety alarming device for tyre of information that the tire pressure deficiency is provided in real time.
Background technology
In modern society, riding instead of walk with automobile is unusual general phenomenon, yet, though automobile has brought facility for people, the probability of relative raising accident.
General automobile accident is except artificial careless mistake, main is the routine inspection of having ignored automobile, especially for the detection of pressure of tire, when maintaining except getting back to maintenance factory, whether just can be tested tire pressure by the maintenance technician enough, although tire pressure is lower than standard value at ordinary times, and the driver also often fails to discover immediately.Thus,, will make that Tyte Wear speeds up, and increase consumption of fuel when tire pressure maintains not enough state.And if tire is because of damage causes when losing heart phenomenon, and the driver is handled in advance as failing, will the harm automobile in personnel's life security.
In view of this, in order to improve above-mentioned shortcoming, tyre pressure safety alarming device for tyre can be sent warning signal when low tyre, remind the driver to replenish tire pressure, to guarantee driving safety, long-pending experience and the constantly research and development improvement for many years of contriver has generation of the present invention then.
Summary of the invention
Main purpose of the present invention is providing a kind of tyre pressure safety alarming device for tyre, make the tire pressure of air chamber in the valve and tire keep balance by inflation, and in the pressure of tire deficiency, during gaseous tension lack of equilibrium in air chamber and the tire, make the air in the air chamber promote a switch, to trigger the structure of alarming device via a pressure output end, the information of tire pressure deficiency can be provided in real time, with make-up gas, and can prolong tire service life, reduce consumption of fuel and reduce the probability of driving accident.
Secondary objective of the present invention is providing a kind of tyre pressure safety alarming device for tyre, when the tire pressure by air chamber in valve and tire keeps balance, one switch remains on the structure of off state, can avoid the power consumption of battery pack, and can be installed on the tire for a long time.
