Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.

As shown in fig. 1 to 7, a testing device for a tire pressure sensor includes a fixing mechanism 3 and two cylinders (a left cylinder 1 and a right cylinder 2), the fixing mechanism 3 is a circular cavity with two ends communicated with each other, pistons 6 of the two cylinders respectively extend into the fixing mechanism 3 from two ends of the circular cavity, threaded holes are formed around the middle portion of the fixing mechanism 3, and the tire pressure sensor 4 is fixed in the threaded holes.

An O-shaped sealing ring 5 is arranged between the cylinder piston 6 and the fixing mechanism 3.

An O-shaped sealing ring 5 is arranged between the tire pressure sensor 4 and the fixing mechanism 3.

The tire pressure sensor 4 is installed on the fixing mechanism 3, the threads are screwed to enable the tire pressure sensor to be attached to the fixing mechanism 3 tightly, sealing is achieved through the O-shaped sealing ring, and the same tire pressure sensor 4 is installed in other threaded holes of the fixing mechanism 3.

2.4-2.6 bar air pressure is added into the cavity through the tire pressure sensor 4, and at the moment, the cylinder is started to move irregularly.

At this time, the output data of the tire pressure sensor 4 is observed and tested.
