[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] like Figures 1-5 As shown, the sensor calibration positioning seat for the spoked wheel module provided in this embodiment includes a base plate 1, on which a longitudinally extendable bracket 2 is connected. The movable end of the bracket 2 is provided with a stabilizing mechanism 3 for stabilizing the spoked wheel body 8 and a driving component 4 for driving the spoked wheel body 8 to rotate. The spoked wheel body 8 is a spoked wheel in the prior art, such as... Figure 1 As shown, it mainly includes a rim 16, spokes 17 and a hub 18. The specific connection method of the structure is not described in detail, but the hub 18 is provided with a shaft hole for connecting with the frame axle.

[0024] Support 1 2 includes a fixed tube 11 connected to the base plate 1 and a longitudinal rod 12 sliding on the fixed tube 11, with a device plate 13 connected to the end of the longitudinal rod 12; stabilizing mechanism 3 includes a tensioning shaft 14 rotatably connected to the end of the device plate 13.

[0025] The fixed tube 11 mentioned above is connected to a telescopic rod 19. The movable end of the telescopic rod 19 is connected to the longitudinal rod 12 through the connecting plate 20. The tensioning shaft 14 is a common structure in the art. In this device, it is mainly used to stabilize the spoke body. The tensioning shaft 14 includes, but is not limited to, a circular guide plate 21. The guide plate 21 has a guide groove 22 radially opened around the central axis. An arc plate 26 is slidably connected to the guide groove 22. The interior of several arc plates 26 forms a hollow structure. A push rod 25 is slidably connected through the guide plate 21. The push rod 25 is provided with a jacking rod 23 corresponding to the arc plate 26. The two ends of the jacking rod 23 are respectively hinged to the arc plate 26 and the push rod 25. The device plate 13 is also equipped with a telescopic rod 24. The movable end of the telescopic rod 24 is rotatably connected to the end of the push rod 25. When the movable end of the telescopic rod 24 moves, it will drive the push rod 25 to slide on the guide plate 21.

[0026] like Figure 5 As shown, when the push rod 25 slides, it will push the arc plate 26 away from or closer to the push rod 25 through the push rod 23, thereby achieving the purpose of stably connecting the stabilizing mechanism 3 with the shaft hole on the spoke body 8. Under the action of the guide groove 22, several arc plates 26 can adjust their distance from the push rod 25 to adapt to the shaft holes on different spoke bodies 8, thereby increasing the adaptability of the device.

[0027] like Figure 4 As shown, the driving component 4 mentioned above includes a driving pulley 27, a driven pulley 28, a transmission belt 29, and a rotating motor 30. The rotating motor 30 is mounted on the device plate 13. The driving pulley 27 is rotatably connected to the device plate 13 via a rotating shaft, while the driven pulley 28 is sleeved and connected to the guide plate 21. The transmission belt 29 is sleeved on the driving pulley 27 and the driven pulley 28. In use, the rotating motor 30 drives the driving pulley 27 to rotate, which in turn drives the driven pulley 28 to rotate via the transmission belt 29. Finally, it drives the guide plate 21 to rotate. Since the arc plate 26 is in close contact with the inner wall of the spoke shaft hole, the rotating motor 30 will eventually drive the spoke body 8 to rotate on the device plate 13.

[0028] To achieve the calibration and positioning of the sensor, such as Figure 3As shown, a horizontal adjustment component 5 is also provided on the base plate 1, a vertical adjustment component 6 is provided on the horizontal adjustment component 5, and a sensor 7 is provided on the vertical adjustment component 6. The sensing end of the sensor 7 faces the spoke wheel body 8. The sensor is a laser displacement sensor in the prior art. Its working principle will not be described in detail. In this device, the sensing end of the sensor 7 will detect the distance between the sensing end and the spoke wheel body. When the spoke wheel body rotates and wobbles, the distance between the spoke wheel body and the sensing end of the sensor 7 will change, thereby detecting the swing amplitude of the spoke wheel body.

[0029] Secondly, the above-mentioned device also includes a controller 15, which is electrically connected to the vertical adjustment member 6 and the horizontal adjustment member 5. It is mainly used to control the operation of the horizontal adjustment member 5 and the vertical adjustment member 6. After the device is assembled, when the spoke wheel body 8 is fixed, the controller 15 drives the horizontal adjustment member 5 to run according to the diameter of the spoke wheel body 8, thereby adjusting the distance between the sensor and the spoke wheel body. Then, the controller 15 drives the vertical adjustment member 6 to run, thereby controlling the sensor to move away from or closer to the wheel rim 16 and adjusting the position of the sensor in the radial direction of the spoke wheel body. Then, the drive member 4 is used to rotate the spoke wheel body, and the controller 15 starts the sensor movement, so that the swing amplitude of the rotating spoke wheel body can be detected.

[0030] When replacing the spoke body with another one for yaw detection, the spoke body can be disassembled and reassembled through the stabilizing mechanism 3, and then the vertical adjustment component 6 and the horizontal adjustment component 5 can be adjusted and calibrated using the controller 15. This will increase the accuracy of the sensor during use and avoid affecting the sensor's detection accuracy due to excessive or insufficient distance.

[0031] Next, to achieve the aforementioned adjustment effect of sensor position change, such as Figure 3 As shown, the lateral adjustment component 5 includes a lateral groove plate 51, a sliding block 52, a threaded rod 53, and a motor 54. The lateral groove plate 51 is located below the spoke wheel body 8 and connected to the base plate 1. A sliding groove 55 is provided on the lateral groove plate 51, and the sliding block 52 slides on the sliding groove 55. The threaded rod 53 is rotatably connected to the lateral groove plate 51, and the motor 54 is installed on the lateral groove plate 51. One end of the threaded rod 53 passes through the end of the sliding groove 55 and is connected to the output end of the motor 54. In use, the motor 54 drives the threaded rod 53 to rotate, thereby driving the sliding block 52 to slide in the sliding groove 55 on the lateral groove plate 51, thereby adjusting the lateral position of the vertical adjustment component 6.

[0032] The vertical adjustment component 6 includes a sliding tube 61 with an opening at one end and an extension rod 62 sliding on the sliding tube 61. The sliding tube 61 is longitudinally connected to the sliding block 52. The vertical adjustment component 6 also includes a rack 63, a rotating gear 64, and a second motor 65. The extension rod 62 has a mounting groove 66, and the rack 63 is installed in the mounting groove 66. The side wall of the sliding tube 61 has a through groove 67 corresponding to the mounting groove 66. The rotating gear 64 is rotatably mounted on the outer side wall of the sliding tube 61. The second motor 65 is mounted on the outer side wall of the sliding tube 61, and the output end of the second motor 65 is connected to the rotating gear 64. A support rod 9 is connected to the top of the extension rod 62. The end of the support rod 9 is hinged to a mounting base 10. The sensor 7 is adapted to be mounted on the mounting base 10. In use, the motor 65 drives the rotating gear 64 to rotate, which in turn drives the rack 63 meshing with it to move. The rack 63 then drives the extension rod 62 to slide up and down, which in turn drives the support rod 9 to move in the vertical direction. Finally, it drives the sensor to move. Since the end of the support rod 9 is hinged to the mounting base 10, and a corresponding damping ring is provided at the hinge, the coefficient of friction between the support rod 9 and the mounting base 10 is changed, thereby ensuring that the sensor and the mounting base 10 can remain stable on the support rod 9 when the sensor is rotated.
