In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes an implementation method of the present invention based on its overall structure.

[0030] like Figures 1 to 5 As shown, the present invention discloses an abnormal noise detection device for a car tailgate motor, which is used to detect whether there is noise and abnormal vibration when the car tailgate motor 1 is running, and includes:

[0031] A clamping device 2, the clamping device 2 is used to clamp and fix the automobile tailgate motor 1, the clamping device 2 includes a brake module 21, the brake module 21 is located at the end of the clamping device 2, and is used to drive the automobile tailgate motor 1 to rotate;

[0032] A detection device, the detection device includes a display module 31, a microphone module 32 and a laser seismometer 33, the microphone module 32 and the laser seismometer 33 are both connected to the display module 31, the microphone module 32 is close to the automobile tailgate motor 1, and the laser seismometer 33 emits laser to detect the center position of the automobile tailgate motor 1;

[0033] A workbench 4, the workbench 4 is used to carry the clamping device 2 and the detection device;

[0034] The power module 5 is used to provide a power source.

[0035] By means of the above structure, the automobile tailgate motor 1 is clamped and fixed by the clamping device 2, the detection device is connected to the power module 5, and the positions of the microphone 321 module 32 and the laser seismometer 33 are adjusted so that the microphone 321 module 32 is close to the automobile tailgate motor 1 to be detected, and the laser emitted by the laser seismometer 33 is aimed at the center of the automobile tailgate motor 1. After the preparation is completed, the automobile tailgate motor 1 to be detected is powered on, and the automobile tailgate motor 1 is operated in a cycle of four seconds forward and four seconds reverse, and the detection device is responsible for collecting the detection data.

[0036] Specifically, the workbench 4 has a shock-absorbing function. The clamping device 2 and the detection device are both installed on the workbench 4. One end of the clamping device 2 is a brake module 21 for driving the automobile tailgate motor 1 to rotate, and the other end is a clamping wrench. The clamping wrench is connected to the clamping head. When the clamping wrench is upward, the clamping head is in a relaxed state. The automobile tailgate motor 1 is placed in the clamping device 2, and the clamping wrench is pulled downward. The clamping head clamps the automobile tailgate motor 1 to fix it. The detection device is composed of a microphone 321 module 32 and a laser seismometer 33. During detection, the microphone 321 module 32 is placed as close to the automobile tailgate motor 1 as possible. At the same time, the laser emitted by the laser seismometer 33 is aimed at the center of the automobile tailgate motor 1. The laser beam is reflected back from the surface of the object to be tested, and the laser seismometer 33 receives the reflected light. Due to the vibration of the object, the phase of the reflected light will change, thereby generating interference. The built-in processing unit of the laser seismometer 33 analyzes the collected laser signals, converts them into parameters such as vibration amplitude and frequency, and displays them on the display module 31 of the detection equipment, providing detection data for the operator's reference.

[0037] Among them, Figure 5 As shown, the microphone 321 module 32 includes a microphone 321 and a telescopic cylinder 322. The microphone 321 is installed at the free end of the telescopic cylinder 322 and changes position with the telescopic cylinder 322. When detection is required, the telescopic cylinder 322 extends to send the microphone 321 to the side of the car tailgate motor 1 to detect noise; after the detection is completed, it is retracted to avoid interference with the clamping device 2.

[0038] like Figure 4 As shown, the laser seismometer 33 is also connected to the adjustment turntable 34, which includes a rotating plate 341, a first adjustment plate 342 and a second adjustment plate 343. The first adjustment plate 342 and the second adjustment plate 343 are both provided with linear tracks. The first adjustment plate 342 is provided with linear tracks along the up and down vertical directions, and the second adjustment plate 343 is provided with linear tracks along the front and back horizontal directions. The laser seismometer 33 is installed on the rotating plate 341, and the rotating plate 341 is connected to the first adjustment plate 342. The rotating plate 341 can rotate with its horizontal center as the axis, thereby driving the laser seismometer 33 to rotate to adjust the angle of its laser emission.

[0039] In this embodiment, a soundproof box 6 is also included. The soundproof box 6 is a box body with a hollow interior and can be closed. The clamping device 2 and the detection device are installed in the soundproof box 6. The soundproof box 6 includes a base 61 and an upper cover 62. The upper cover 62 is rotatably connected to the base 61. The upper cover 62 can be a transparent shell, and the operator can observe the situation inside the soundproof box 6 through the upper cover 62.

[0040] like Figure 1 and Figure 2As shown, a pushing cylinder 63 is installed on each side of the sound-absorbing box 6, one end of the pushing cylinder 63 is connected to the base 61, and the other end is connected to the upper cover 62. Since the base 61 and the upper cover 62 are rotatably connected, the upper cover 62 of the sound-absorbing box 6 can be lifted when the pushing cylinder 63 is extended, thereby opening the sound-absorbing box 6, and the staff can operate or repair the equipment in the sound-absorbing box 6.

[0041] In this embodiment, the workbench 4 is installed in the soundproof box 6, and the workbench 4 includes a first platform 41 and a second platform 42. The clamping device 2 is installed on the first platform 41. The detection device can be installed on the first platform 41 or the second platform 42. The first platform 41 and the second platform 42 are arranged in parallel. A number of seismic isolation rubber blocks 43 are arranged between the first platform 41 and the second platform 42 for shock absorption, and a seismic isolation foot cup 44 is installed on the bottom surface of the second platform 42 and connected to the base 61 of the soundproof box 6.

[0042] In this embodiment, a half-enclosed frame 7 is provided on the outside of the soundproof box 6. The opening direction of the frame 7 is the same as the opening direction of the soundproof box 6. A safety grating 71 is also installed at the opening of the frame 7, which can effectively prevent accidents and avoid operators from accidentally entering dangerous areas during the detection process, thereby enhancing the safety of the working environment.

[0043] In this embodiment, the frame 8 carries the mute box 6 to ensure the stability of the entire device and prevent tilting or displacement caused by vibration or external force during use. The bottom of the frame 8 is also equipped with a shockproof foot cup 81 and a caster 82. The shockproof foot cup 81 can effectively absorb ground vibration and reduce the impact of external vibration on the device, thereby improving the detection accuracy. The caster 82 allows the device to be easily moved between different workplaces, improves the flexibility and applicability of the device, and facilitates detection in different environments.

[0044] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
