TWI796124B - Air nozzle with tire pressure monitor - Google Patents

Abstract

The present invention is an air nozzle with a tire pressure detector, which includes a valve body, a tire pressure detector, a control ring and a fixing ring. The air nozzle body can swing up and down to find the most suitable position when passing through the rim, and then use the continuous rotation control ring to cooperate with the rim and the fixing ring to pull the air nozzle body outwards so that the axis is pressed against the curved surface of the tire pressure detector In order to achieve a fixed angle between the valve body passing through the perforation and the rim, this structure solves the need to manually adjust and lock the angle of other in-tire tire pressure detectors when the valve body passes through the rim. The above fixed action is changed to self-adaptive, which reduces the possibility of manual operation errors, and makes it easier to install the tire pressure detector inside the tire and has better applicability.

Description

Air nozzle with tire pressure monitor

The utility model relates to an air nozzle attached to a tire pressure detector applied to a tire.

Among the modern traffic accidents, the accidents caused by tire failure account for a very high proportion, especially when the motor vehicle is running at high speed, a sudden tire failure will lead to serious accident results. Therefore, it is an important issue that cannot be ignored before the driver checks the tire pressure of the motor vehicle he is driving.

In the ancient technology, the method of measuring tire pressure usually requires manual use of a tire pressure measuring device to measure the tire pressure of each tire one by one, which is quite troublesome and time-consuming, causing many drivers to be reluctant to measure, resulting in traffic accidents Rise, therefore, some industry later developed a wireless tire pressure detector, put the tire pressure detector inside the tire and connect each tire pressure detector to the host through wireless connection and transmit data to the host, so that The host can directly display the tire pressure of each tire for the driver to judge.

Of course, the wireless tire pressure detector is divided into the outside type wireless tire pressure detector and the inside type wireless tire pressure detector. The price of the outside type wireless tire pressure detector is lower but it may damage the tire pressure. mouthpiece and easy to be stolen, while the in-wall wireless tire pressure detector has the disadvantages of high price, difficult installation, and unstable installation will affect the accuracy and shorten the life of the tire pressure detector.

The inner-type tire pressure detectors that appear on the market are usually in the form of air nozzles attached to the tire pressure detectors. As shown in the seventh figure, the inner-type tire pressure detector disclosed in the Republic of China No. M599386 7 ,Tie Through the use of the valve body 71 to penetrate and lock the rim, and then use the screw 72 to lock and fix the valve body 71 at an appropriate angle, so that the tire pressure detector 73 is difficult to fall and stick to the rim, reducing the tire pressure. There is no risk of the pressure detector 73 falling or being damaged.

But this kind of design has the disadvantage of needing to manually adjust to a specific angle and fix it with screws after the rim is worn. At the same time, because the manual adjustment and locking of the screws are complicated and cumbersome to operate, once the setting is wrong, there is still There is a high probability of damaging the tire pressure detector and affecting the detection results, so there are doubts about its practicality.

Therefore, if the above situation can be optimized and improved, and the possible problems and convenience caused by fixing the tire pressure detector in the tire can be reduced, the willingness of drivers to replace the tire pressure detector in the tire can be effectively increased and consumers’ desire to purchase can be increased. .

The main purpose of the present invention is to provide an air nozzle with a tire pressure detector. Using the structure of the upper axis of the tire pressure detector and the perforation to cooperate with gravity, the air nozzle body can swing up and down when passing through the rim to find the most suitable position. position, and then use the continuous rotation of the control ring to cooperate with the rim and the fixing ring to pull the air nozzle body outwards so that the axis is pressed against the curved surface of the tire pressure detector to achieve a fixed angle between the air nozzle body passing through the hole and the rim.
