Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] See also Figure 1-2 The utility model provides a technical solution: an external tire pressure sensor vibration test fixture capable of adding air pressure, comprising:

[0027] The fixture seat 1 has an L-shaped cross section;

[0028] The sealed cabin 2 is fixedly mounted on the fixture seat 1. A cavity is arranged inside the sealed cabin 2. An inflation connector 21 is arranged at one end of the sealed cabin 2. The inflation connector 21 is connected to the cavity. The inflation connector 21 is used to connect to the air source. The sealed cabin 2 is also provided with a plurality of sensor connectors 22 arranged along its length direction. The external tire pressure sensor is fixedly mounted on the sensor connector 22.

[0029] The inflation connector 21 is a quick-insertion connector, and the quick-insertion connector on the sealed cabin 2 can be connected to an external air source through a PU tube, so as to improve the plugging and unplugging efficiency.

[0030] The sealed cabin 2 is provided with five sensor connectors 22 arranged at equal distances, and multiple external tire pressure sensors can be tested simultaneously, thereby improving the test efficiency and effectively ensuring the accuracy of the sealing test.

[0031] The fixture seat 1 includes a first mounting plate 11 and a second mounting plate 12, the first mounting plate 11 is provided with a first mounting hole 111, and the second mounting plate 12 is provided with a second mounting hole 121. The sealed cabin 2 is provided with a bolt hole 23. The test fixture can be fixed to the vibration table through the bolt hole 23 on the sealed cabin 2, the first mounting hole 111 on the first mounting plate 11, or the second mounting hole 121 on the second mounting plate 12, to achieve three-axis fixation with the vibration table. The test fixture can be installed in three axes to achieve three-axis vibration testing on a single-axis vibration table, effectively improving the test effect.

[0032] Working principle: A rectangular sealed cabin 2 is set on the fixture base 1. The sealed cabin 2 is installed with an external tire pressure sensor through the sensor connector 22 thereon. The external tire pressure sensor is locked with the sensor connector 22 according to the specified torque. After that, the fixture base 1 and the sealed cabin 2 are fixedly installed on the vibration table. After starting the vibration table, the required air pressure can be applied to the sealed cabin 2 through the air source, and the air pressure in the sealed cabin 2 can be monitored in real time through the pressure gauge connected to the air source. If the air pressure drops, it means that the sealing of the external tire pressure sensor has failed. Therefore, the test fixture can pass compressed air of a specified air pressure into the external tire pressure sensor while performing the vibration test, so as to realize the vibration test and monitor the sealing of the external tire pressure sensor at the same time.

[0033] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
