Abstract
The invention discloses a valve core type tire pressure detecting device. A tire pressure detecting device is added on a valve core to manufacture a novel valve core type tire pressure detecting device, during installation, the tire valve core is just replaced, thus the installation is simple and convenient. According to the invention, an air pressure sensor and a wireless communication module are processed to a wafer, the wafer is arranged at one end of the inner side of a mandril (the inner side of the mandril is the end close to the axle center of the tire of the mandril), thus not only decreasing the mass, but also arranging the wafer at a position closer to the axle center of the tire to reduce the centrifugal force. In addition, by adopting the valve core type tire pressure detecting device provided by the invention, only the valve core of the original vehicle is replaced, which is a part of the original vehicle, if the masses of the valve core, the wafer and the battery are reasonably designed, the mass of the valve core type tire pressure detecting device can be the same as that of the valve core of the original vehicle, in this way, the centrifugal force can not be increased due to the tire pressure detecting device; while the other tire pressure detecting devices need to be independently arranged and no part on the original vehicle is replaced, thus the mass of the wheel is absolutely increased to generate the centrifugal force.
Description
Technical field
The present invention relates to the detection of tire pressure, in particular valve-inside type tire pressure detecting device.
Background technology
The effect that tire pressure detects carries out real time automatic detection to tire pressure in vehicle traveling process, and report to the police to tire flat and infrabar, to guarantee traffic safety.
During running car, if tire pressure is too high, then can reduce the area of contact on tire and ground, the pressure that at this moment tire bears improves relatively, and the earth-grasping force of tire can be affected.In addition, when vehicle is through ditch or road surface of jolting, in tire, there is no sufficient space absorbing vibration, except impact travel stability and travelling comfort except, also can cause and the impact of suspension is put more effort, also can bring harm thus.Meanwhile, the hidden danger of blowing out when high temperature also can increase accordingly.
Tire pressure detects and is divided into two kinds: direct-type tire pressure detects and indirect type tire pressure detects.It is utilize to be arranged on the air pressure that each pressure sensor of taking turns tyre cavity directly measures tire that direct-type tire pressure detects, and utilizes wireless launcher to be sent to central receiver module by pressure information from inside tires, then shows each tire pressure information.When tire pressure is too low or leak gas, system can automatic alarm.The principle of work that indirect type tire pressure detects is: when the air pressure of certain tire reduces, the weight of vehicle can make this theoretical running radius of tire of taking turns diminish, and causes other wheels of its revolution ratio fast.By the rotating speed difference between comparative tire, to reach the object monitoring tire pressure.Indirect type tire warning is actually and relies on calculating tire rolling radius to detect air pressure.
Direct-type tire pressure detects the actual wink that can measure each inside tires at any time and presses, and is easy to determine fault tire, and therefore, the application of direct-type tire pressure detecting device is comparatively general.Existing direct-type tire pressure detecting device is divided into two kinds, and one is built-in tire pressure detecting device, and another kind is external tyre pressure detecting device.The installation process of built-in tire pressure detecting device comparatively bothers, and needs to unload tire, is then implanted by built-in tire pressure detecting device; Although external tyre pressure detecting device installation process is simpler, only need be arranged on tyre valve, but shortcoming is external tyre pressure detecting device certain mass (existing external tyre pressure detecting device quality is larger), could use because needs are arranged on tyre valve, destroy the mass distribution of tire, when tire rotates, external tyre pressure detecting device can produce centnifugal force, and then destroys the kinetic balance of tire, and external tyre pressure detecting device also affects tire outward appearance.
