Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, a moving mechanism on a wheel arch height measuring device includes an aluminum profile frame 1; a guide rail 2 is disposed on one side of the aluminum profile frame 1, a slider 3 is slidably connected to the top of the guide rail 2, and a column assembly 5 is fixedly connected to the top of the slider 3; the aluminum profile frame 1 serves to support the structure, ensure measurement stability, provide an installation interface, and reduce the overall weight. Since the column assembly 5 is fixed to the top of the slider 3, and the slider 3 slides on the top of the guide rail 2, when the column assembly 5 is subjected to force, the column assembly 5 can slide above the guide rail 2. The column assembly 5 is usually designed to be height-adjustable to adapt to the measurement needs of different vehicle models and wheel arch heights. By adjusting the height of the column assembly 5, the measuring element can be accurately positioned at different positions on the wheel arch for measurement. It should be noted that the column assembly 5 is prior art and will not be described in detail here.

[0025] The belt drive assembly 4 is located below the column assembly 5. The belt drive assembly 4 includes a synchronous belt 41 fixed to the bottom of the column assembly 5. A synchronous pulley 42 is driven to the inner wall of the synchronous belt 41. A servo motor 43 is fixed to the inner wall of the synchronous pulley 42. A reducer 44 is provided on one side of the servo motor 43. The synchronous belt 41 and the synchronous pulley 42 transmit motion and power through the meshing of teeth, which has the characteristics of accurate transmission and high efficiency. The servo motor 43 serves as a power source, receives control signals and accurately controls the speed and position to ensure the accuracy of the measurement process. The reducer 44 is used to reduce the speed and increase the torque to adapt to different load requirements. The combination of the four enables the wheel arch height measuring device to achieve efficient and stable measurement operations.

[0026] A positioning seat 6 is installed on one side of the aluminum profile frame 1, and a mounting seat 7 is fixedly connected to the top of the positioning seat 6. The positioning seat 6 is designed to facilitate connection with the aluminum profile frame 1 and to fix the mounting seat 7, thereby improving the stability of the mounting seat 7 and facilitating the installation of the synchronous pulley 42.

[0027] A mounting plate 8 is bolted to the top of the slider 3. A support plate 9 for fixing the column assembly 5 is bolted to the top of the mounting plate 8, and multiple sets of support plates 9 are provided. A connecting plate 10 is fixedly connected to one side of the mounting plate 8, and the inner wall of the connecting plate 10 is slidably connected to the outer side of the guide rail 2. A movable plate 15 is fixedly connected to the bottom of the synchronous belt 41, and one side of the movable plate 15 is fixedly connected to one side of the connecting plate 10. Since the mounting plate 8 is fixed to the top of the slider 3, the mounting plate 8 can be moved when the slider 3 moves. At the same time, the support plate 9 is fixed to the top of the mounting plate 8, so the support plate 9 can be moved when the mounting plate 8 moves, thereby moving the column assembly 5. The design of the connecting plate 10 facilitates the connection between it and the movable plate 15, and the movable plate 15 is connected to the synchronous belt 41. Therefore, when the synchronous belt 41 rotates, it can move the movable plate 15 and the connecting plate 10, thereby facilitating the transmission of the mounting plate 8.

[0028] A fixing plate 11 is bolted to one side of the slider 3, and a pointer 12 is bolted to one side of the fixing plate 11. A fixing block 13 is fixed to one side of the aluminum profile frame 1, and a scale plate 14 for measurement and calculation is fixed to one side of the fixing block 13. The design of the fixing plate 11 facilitates the fixing of the pointer 12, while the fixing block 13 fixes the scale plate 14. Thus, the pointer 12 is used to intuitively indicate the measurement position or height, and the scale plate 14 provides the measurement benchmark and reading reference. The two work together to achieve fast and accurate measurement.

[0029] Working principle: First, the servo motor 43 is turned on. The servo motor 43 serves as the power source, receiving control signals and outputting rotational motion. The reducer 44 is connected to the servo motor 43, reducing the speed and increasing the torque to meet the measurement requirements. The synchronous belt 41 and the synchronous pulley 42, through tooth-to-tooth meshing, convert the rotational motion of the reducer 44 into linear movement, driving the measuring element to move up and down along the column assembly 5. The column assembly 5 provides stable support and guidance, ensuring the accuracy and stability of the measuring element during movement. The entire system achieves accurate measurement of the wheel arch height by precisely controlling the movement of each component.
