In-tire tire pressure detecting device

The present invention relates to a tire pressure detecting device, and more particularly to an in-tire tire pressure detecting device.

With the development of technology, the automotive industry has also developed many high-end technology equipment. For example, for safety, the driver wants to know the internal pressure of the tire, and only needs to wirelessly transmit the data to the display in the vehicle through the tire pressure detecting device provided on the tire, and the current tire pressure condition can be immediately known. Therefore, it can avoid traffic accidents caused by insufficient tire pressure.

At present, the tire pressure detecting device can be roughly divided into two types, one of which is an inner tire type, as shown in FIG. 1A, which is attached to the tire 8 including the air nozzle 80, the wheel frame 81 and the tire skin 82, and the tire pressure detection is performed. The measuring device 1 is mounted on the wheel frame 81 and communicates with the inner mouth end of the air nozzle 80 for inflation, so that the tire skin 82 covers the tire pressure detecting device 1; the other is a tire external type, which is a tire pressure detecting device. Directly mounted on the exposed end of the gas nozzle.

As shown in FIG. 1B, the conventional intra-tire tire pressure detecting device 1 includes: a detecting processor 11 having a vent 110, and a docking member 10 for connecting the detecting processor 11 and the air nozzle 80. When the clamping mechanism 100 of the docking member 10 is clamped to the wheel frame 81, the detecting processor 11 and the air nozzle 80 are respectively located inside and outside the wheel frame 81, and Detective The test processor 11 is wrapped in the tire skin 82 of the tire 8.

When the in-tire tire pressure detecting device 1 is used, the detecting processor 11 determines the intra-fetal pressure according to the flow rate of the gas entering and leaving the air hole 110, and wirelessly transmits the obtained information to the display in front of the driver's seat in the vehicle. For the driver's reference.

However, when the tire-type tire pressure detecting device 1 is mounted on the tire 8, the detecting processor 11 does not abut the surface of the wheel frame 81, causing the detecting processor 11 to sway when the car travels. The accuracy of the tire pressure detection is affected, and when it is serious, the detection processor 11 may fall off.

Therefore, how to overcome the problems in the prior art is an urgent need of the industry.

In view of the above-mentioned lack of the prior art, the present invention provides an in-tire tire pressure detecting device, comprising: a connecting component connected to a nozzle provided on a tire, and comprising at least one hollow rod-shaped body, and The end surface of the body is a concave surface; and the detecting processor is configured to detect the tire pressure of the tire and has a corresponding convex portion in contact with the concave surface.

In the above-described intra-tire tire pressure detecting device, the detecting processor has a fixing member fixed to the connecting component to combine the detecting processor and the connecting component. For example, the inner wall of the body is formed with a bump, and the fixing member is fixed to the detecting processor and the connecting component, so that the fixing member abuts against the protruding block, and the protruding block is a curved surface convex block.

In the above-described intra-fetal tire pressure detecting device, in the above-described intra-tire tire pressure detecting device, the connecting component is further included for fixing the tire-in-tube tire pressure detecting device A clamping mechanism mounted on the tire. For example, the clamping mechanism is formed by an annular convex ring protruding from the outer surface of the body and a collar sleeved on the body. Alternatively, the connecting component includes a reinforcing member for stabilizing the clamping mechanism, and the reinforcing member is a non-flat ring body.

In the above-described intra-tire tire pressure detecting device, the detecting processor further includes a circuit board, a housing for accommodating the circuit board, and an opening on the housing, and the opening is for the connecting component The body is inserted therein.

It can be seen from the above that the tire pressure detecting device of the present invention mainly uses the concave surface and the convex portion to design the concave surface against the convex portion. Therefore, compared with the prior art, the tire pressure detecting device is installed on the tire pressure detecting device. After the tire, the detection processor can be fine-tuned so that the detection processor can abut the surface of the wheel frame to prevent the detection processor from shaking when the car is traveling.
