[0025] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0026] An automotive sensor performance test device includes a support base 1 and a test support base 2 disposed above the support base 1. A baffle 3, a slide rail 4, a rack plate 5, and a fixing bracket 6 are fixedly mounted on the top of the support base 1. An information collector 301 is mounted on the top of the baffle 3. A positioning slider 401 is disposed on the outer side of the slide rail 4. A positioning clamping mechanism 7 is disposed on the right side of the fixing bracket 6. A gear 201 is disposed on the bottom of the test support base 2. An air motor 202 and a test plate 203 are fixedly mounted on the top of the test support base 2.

[0027] Specifically, the outer surface of the slide rail 4 is slidably connected to the inner wall of the positioning slider 401, the top surface of the positioning slider 401 is fixed to the bottom surface of the test support 2, the output end of the pneumatic motor 202 passes through the top surface of the test support 2 and is fixedly connected to the top of the gear 201, and the gear 201 is meshed with the tooth surface of the rack plate 5;

[0028] In this embodiment, the pneumatic motor 202 is set to drive the gear 201 to engage with the rack plate 5, so that the test support 2 can be moved accurately. The cooperation between the slide rail 4 and the positioning slider 401 enables the test support 2 to move smoothly along the slide rail 4, thereby achieving smooth approach between the test plate 203 and the sensor, and then the displacement speed of the test plate 203 is tested by the sensor.

[0029] It should be noted that the information collector 301 is electrically connected to the sensor to be tested via a wire, and can collect the output data of the sensor in real time, which is convenient for subsequent analysis of the quality of the sensor.

[0030] In this embodiment, please refer to Figure 1 and Figure 3 , the positioning and clamping mechanism 7 includes a circular groove 701 and a slide groove 702, both of which are provided on the right side surface of the fixed frame 6, and an electric cylinder 703 is provided inside the slide groove 702, and a push block 704 is fixedly installed on the telescopic end of the electric cylinder 703, and a clamping rubber plate 705 is provided on one side of the push block 704, and an elastic compression spring 706 is fixedly provided on the other end of the push block 704, and a guide rod 707 is movably provided inside the elastic compression spring 706;

[0031] Specifically, the circular groove 701 is connected to the slide groove 702, the left inner wall of the circular groove 701 extends to the left surface of the fixing frame 6, the vertical cross-section of the push block 704 is T-shaped, and the outer surface of its vertical end is in contact with the inner wall of the slide groove 702, the clamping rubber plate 705 is symmetrically distributed front to back about the right central axis of the fixing frame 6, one end of the guide rod 707 is movable through the outer surface of the push block 704 and is fixed to the clamping rubber plate 705, one end of the elastic compression spring 706 is fixed to the outer surface of the guide rod 707, and the other end thereof is in contact with the outer surface of the push block 704;

[0032] In this embodiment, the push block 704 is driven by the electric cylinder 703, so that the push block 704 drives the clamping rubber plate 705 to move, causing the clamping rubber plates 705 to move toward each other and get close to the sensor, thereby achieving the effect of fixing the sensor. The setting of the elastic compression spring 706 and the guide rod 707 can effectively absorb and disperse part of the clamping force exerted on the sensor, avoiding the situation where the sensor is damaged due to excessive clamping force, and meeting the positioning and fixation requirements of the sensor.

[0033] The working process of the present invention is as follows: when using a vehicle sensor performance test device, the sensor to be tested is first moved to place it in the circular groove 701, and then the electric cylinder 703 is started. The telescopic end of the electric cylinder 703 begins to extend and drives the push block 704 to move along the inner wall of the slide groove 702, and the push block 704 drives the clamping rubber plate 705 to move, so that the clamping rubber plate 705 is close to and in contact with the outer surface of the sensor. During the contact process, the guide rod 707 moves and causes the elastic compression spring 706 to extend, and the elastic compression spring 706 can apply pressure when it extends. The clamping force on the sensor is absorbed and dispersed to ensure the clamping effect of the sensor. Finally, the test plate 203 can be displaced and the pneumatic motor 202 can be driven. The output end of the pneumatic motor 202 drives the gear 201 to rotate. With the cooperation of the gear 201 and the rack plate 5, the positioning slider 401 moves along the slide rail 4, realizing the displacement change of the test support 2 and the test plate 203. At this time, the sensor performs multiple tests on the test plate 203 and transmits the data to the information collector 301, which facilitates the subsequent judgment of the sensor performance and meets the needs of users.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
