Abstract
The utility model relates to an air pressure monitor of an automotive vehicle, which comprises an air sealing device, a monitoring device, an air pressure safety device and an alarming device, wherein, the air-sealing, the monitoring and the air pressure safety devices can directly form a whole, or can form a whole through an air-guiding tube. Springs are respectively arranged in the air-sealing, the monitoring and the air pressure safety devices, one end of each spring is connected with a piston of the spring's own, and the other end is fixed to a base of the spring. The utility model has the advantages of small size, convenient installation and reliable performance, and only needs to be connected with screw thread of an air valve of the vehicle tyre. The utility model can be suitable for various automotive vehicles to be used.
Description
The utility model belongs to a kind of motor vehicle tyre pressure monitor, has a cover electronic alarm device.
Self-propelled vehicle in the process of moving, tire is often by things such as the nail gas that punctures or jog, make tire deflation, stop, not only can cause tire to scrap very soon as can not in time finding, and grave accident such as overturning appears easily, result in greater loss, particularly large-scale autotruck or trailer are because load carrying ability is big, as not finding in time that then loss can be bigger.
China's utility model patent, application number is 92225175.4 to disclose a kind of tyre pressure monitor, its formation is that an arch form spring plate is arranged between the tire bowl and the inner tube of a tyre, under normal circumstances, spring plate forms a plane with the tire bowl under the effect of tire pressure, when tire pressure reduces, spring plate arches upward by pipe link, drives the engagement lever motion, makes electronic buzzer warning in the operator's compartment.It is that inconvenience is installed that the tyre pressure of this structure is supervised then its shortcoming of device, and tire is at aspects such as summer in winter, speed, weights, and difference variation is bigger in the tire, causes the pressure measurement of arch form spring plate inaccurate, exists error in observation process.
The purpose of this utility model is to avoid the weak point of above-mentioned prior art, provides a kind of simple in structure, with low cost, easy to install, can be applicable to various power actuated vehicles uses and the tyre pressure monitor that all can monitor at various road travelings.No matter this monitor is in winter or summer, and motor-driven vehicle going is fast or slow, or load and vehicle is many or few, can both accurately monitor dependable performance.
The purpose of this utility model also is to have solved one when giving Tyre inflating, need not unload valve inside, and charging gas need not be more heavily by the up-to-date technology of dress valve inside, and it is self-styled to reach seal gas device.
The purpose of this utility model is achieved in that and includes a cover seal gas device, a cover monitoring device and a safety device of atmospheric pressure, and wherein seal gas device and monitoring, safety device of atmospheric pressure both can be formed directly in one, also can form one by the ventilation flue.
Said seal gas device is equipped with spring in monitoring device and the safety device of atmospheric pressure, and one end and piston flexibly connect, and the other end is fixed on the spring pedestal.
End at seal gas device has air-filled pore, and the other end is provided with negative thread, is connected with the tire valve.
It is little, easy to install that the utility model has volume compared to existing technology, advantages such as dependable performance, and the tire deficency but actv. is avoided, and chaufeur can't find the loss that causes.
Accompanying drawing is the utility model integral structure section-drawing
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, by seal gas device (1), monitoring device (2), safety device of atmospheric pressure (3) has been formed the utility model, said seal gas device (1), be provided with spring (4,5,6) in monitoring device (2) and the safety device of atmospheric pressure (3), spring (4,5, a 6) end and piston (7,8,9) flexibly connect, and the other end is fixed on the spring pedestal (10,11,12).
The head protector (13) that is threaded on the top of seal gas device (1) gives in it and leaves air-filled pore (14), and the lower end of seal gas device (1) has negative thread (15) and is threaded with the tire valve.
Have the warning whistle (16) in the lower end of safety device of atmospheric pressure (3), which is provided with tarpaulin (17), this tarpaulin is made by elastomeric material, and under the normal circumstances, tarpaulin is shut warning whistle pipe (16).
Be provided with rubber cushion (18,19,20) envelope gas piston (7) at an end of piston (7,8,9) and have the inclined-plane.
When Tyre inflating, head protector (13) to be turned on, gas is by inwardly inflation of air-filled pore (14), at this moment, because the effect of gas, it is downward together with spring (4) to promote piston (7), piston (8) is moved together with spring (5), gas is shut, gas directly charges in the tire.
The tyre pressure abundance stops, and air-flow and envelope gas spring (4) promote to move outside the envelope gas piston (7), and seal gas device (1) is sealed gas.
When tire gas leakage, the tire internal gas pressure is less than giving when deciding spring (5) power, piston (8) leaves envelope gas platform under the effect of spring (5), emit gas, by safety device of atmospheric pressure (3), promote spring (6), piston (9) makes gas be full of warning whistle pipe (16), blow tarpaulin (17) open and send chimes of doom, be installed in electronics in the operator's compartment and specially receive receiving device and pipe simultaneously.After the warning, piston (9) seals gas automatically.
Another embodiment of the utility model is threaded in seal gas device (1) on the tire valve by movable joint (15), and monitoring device (2) and safety device of atmospheric pressure (3) are installed in the tire bowl by the ventilation flue.Piston (9) in safety device of atmospheric pressure (3) is made by insulating material, and an end is provided with conductive copper sheet, is provided with conduction with the corresponding position of this conductive copper sheet and contacts copper sheet, when gas promotes piston (9), conductive copper sheet contacts, and energized makes electronic alarm device send chimes of doom.
Claims (3)
1, a kind of motor vehicle tyre pressure monitor, has a cover electronic alarm device, it is characterized in that: also include a cover seal gas device (1), a cover monitoring device (2) and a safety device of atmospheric pressure (3), wherein seal gas device and monitoring, safety device of atmospheric pressure both can be formed directly in one, also can form one by the ventilation flue.
