Problems solved by technology

In this case, the signal inside the tire is led out of the tire and is no longer easily shielded. However, once water enters the air nozzle and the air nozzle is integrated with the hub, the signal transmission cannot be sent normally due to a short circuit.
And because the relatively large resistance of the gas nozzle affects the signal transmission power and the feed point of the signal to the gas nozzle, it is difficult for this product to be fully recognized by consumers in the market at present.

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0029] The tire pressure signal transmitting device with air nozzle of the present invention is installed on the tire pressure gauge with air nozzle, so its diagram and corresponding description do not depart from the whole body of the tire pressure gauge with air nozzle.

[0030] figure 1 and figure 2 Together show the assembly relationship of the tire pressure gauge with air nozzle of the present invention, wherein the tire pressure gauge 1 is mainly composed of a casing 11 and a circuit board 12, and the circuit board 12 is integrated with tire pressure, temperature and / or humidity and other parameters. The tire pressure detection circuit 123 of the means is also integrated with a transmitting circuit 121 that sends the detection result in the form of a signal (see Figure 5 and Image 6 ), and the integrated battery 122 as a power source, etc. All th...

Abstract

A signal transmission device for a tire pressure gauge with a gas nipple, the tire pressure gauge including a circuit board on which a signal transmission circuit is installed and an enclosure for containing the circuit board therein. The signal transmission device includes: a tire pressure detection circuit for detection of the pressure value inside the tire and transforming the pressure value into electrical signal; the signal transmission circuit, which is mounted on the circuit board for transforming the electrical signal into signal to be transmitted; a cylindrical coil, one end of which is electrically connected with the signal transmission circuit for receiving the signal to be transmitted and radiating the signal to be transmitted out of the tire, while the other end thereof is electrically connected with the gas nipple to function as an impedance match element so as to transmit the signal out of the tire; and the gas nipple connected with the enclosure of the tire pressure gauge in a universal manner, and transmitting the signal out of the tire.

Description

【Technical field】 [0001] The invention relates to automobile security auxiliary equipment, in particular to a signal transmitting device for a tire pressure gauge with an air nozzle. 【technical background】 [0002] It is common knowledge in the art that the tire pressure gauge of the automobile tire is connected with the air nozzle to form an independent product for sale. See the patent documents of various countries in the world including the applicant's patent (application) for the relevant technological evolution. [0003] There are generally two ways for the tire pressure gauge to transmit signals to the space outside the tire. One is to put an antenna on the circuit board of the tire pressure gauge as the product implemented by the applicant, and directly transmit electrical signals to the outside of the tire through the antenna. As we all know, the steel wire mesh is densely covered in the tire, and the steel wire mesh together with the hub forms a shielding cavity, w...
