Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure sensor detection, in particular to a dual-angle test rotary disk for applying air pressure to a sensor. Background Art

[0002] External tire pressure sensors are installed on the tire valve stem. A rotation test is a key quality indicator. This test verifies and simulates the sensor's sealing performance and structural strength under high-speed driving conditions. This test is typically conducted using a rotating test machine. The external tire pressure sensor is mounted on the machine's turntable. The machine uses a motor to drive the turntable at a specified acceleration or speed to verify the sensor's sealing and structural strength.

[0003] The turntables used in existing rotational testing equipment typically lack sealed chambers, making it impossible to apply air pressure during the rotational test, effectively failing to simulate the tire's operating conditions during vehicle operation. Without air pressure, the seals of the external tire pressure sensor and valve stem cannot be verified during the test. Seal verification can only be performed through other means before and after the test, making rotational testing of external tire pressure sensors inconvenient.

[0004] Furthermore, the simulated valve hole on the turntable has a fixed angle after the valve is installed, so only the lateral acceleration tolerance of the external tire pressure sensor can be verified. Given the complexity of the actual installation environment and the differences in vehicle types, external tire pressure sensors for different tire specifications are installed in different orientations, requiring verification of acceleration tolerance in different directions. Utility Model Content

[0005] The purpose of the utility model is to provide a rotary test turntable for a dual-angle test with an air pressure sensor, so as to solve the problem that the existing rotary test equipment cannot simulate the installation conditions of external tire pressure sensors of tires of different specifications and cannot meet the requirements of applying air pressure.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a rotary test turntable for a dual-angle test sensor capable of applying air pressure, comprising:

The first air valves are used to install tire pressure sensors. A plurality of second air valves equidistantly arranged circumferentially are provided on the upper surface of the tubular sealed cabin. The second air valves are used to install tire pressure sensors.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] See also Figure 1-2 The utility model provides a technical solution: a rotary test turntable for a dual-angle test sensor capable of applying air pressure, comprising:

[0028] Turntable body 1;

[0029] A tubular sealed cabin 2 is fixedly mounted on the outer surface of the turntable body 1. A cavity is provided inside the tubular sealed cabin 2. The outer surface of the tubular sealed cabin 2 is provided with a plurality of first air valves 21 equidistantly arranged circumferentially. The first air valves 21 are used to install the tire pressure sensor 3. The upper surface of the tubular sealed cabin 2 is provided with a plurality of second air valves 22 equidistantly arranged circumferentially. The second air valves 22 are used to install the tire pressure sensor 3.

[0030] The cross section of the tubular sealed cabin 2 is circular. The turntable body 1 is welded with the circular tubular sealed cabin 2 on the basis of the wheel-shaped plane to ensure balanced air pressure and facilitate testing.

[0031] The first valve 21 and the second valve 22 are staggered, which facilitates the installation of the tire pressure sensor 3 and prevents the tire pressure sensor 3 from being affected by the adjacent tire pressure sensor 3 during testing.

[0032] The number of first valves 21 is 36, and the number of second valves 22 is 12. With 12 valves installed on the top of the tubular sealed cabin 2 and 36 valves installed on the side, the entire turntable can test up to 48 tire pressure sensors simultaneously, improving testing efficiency.

[0033] Working Principle: By adding a sealed chamber to the original rotating fixture, air pressure can be applied during the rotation test. External tire pressure sensors 3 are installed on the first and second valves 21, 22 of the tubular sealed chamber 2. The horizontal first valve 21 and the vertical second valve 22 enable dual-angle testing of the sensors. When using the rotating test turntable, external tire pressure sensors 3 are installed on the first and second valves 21, 22 of the tubular sealed chamber 2. Compressed air of a specified pressure is then filled into the unused first or second valve 21, 22 of the tubular sealed chamber 2. The turntable body 1 is then mounted on the rotating shaft of the rotating test machine. When the rotating test machine is turned on, the turntable rotates at a set speed, and the air pressure detected by the external tire pressure sensor is monitored via the sensor's signal receiving device. A drop in air pressure indicates a seal failure.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
