Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive testing technology, specifically to an automotive four-wheel alignment testing platform. Background Technology
[0002] A four-wheel alignment machine is a professional device used to detect and adjust the alignment parameters of a car's wheels. Its main functions include detecting parameters such as the car's chassis, toe-in, camber, kingpin, push-out angle, and frame diagonal to ensure the stability, safety, and comfort of the car during driving.
[0003] According to Chinese Patent No. CN216050734U, a four-wheel alignment test platform for automobiles includes two side support baffles, and bottom support plates are fixedly connected to both sides of the opposing side walls of the two side support baffles. This utility model allows for easy disassembly of the platform bridge plate and upper and lower ramp plates by inserting a hexagonal stirring handle into the lifting adjustment hexagonal hole and rotating the limiting post into the threaded hole, so that the top of the limiting post is lower than the top of the threaded hole. This ensures that the limiting post is always located inside the bottom support plate and prevents it from being lost after disassembly. By inserting the adjusting stirring handle into the transverse adjustment hexagonal hole, the adjusting screw is rotated. Under the transmission of the thread, the platform bridge plate and the upper and lower ramp plates can be moved back and forth under the guidance of the sliding groove and the slider, so as to adjust the spacing of the platform bridge plate. The adjustment is convenient, quick and easy, saves time and effort, and has good stability.
[0004] In the above solution, the height of the platform cannot be adjusted. A four-wheel alignment test platform that cannot be adjusted in height may not be suitable for all types of vehicles. Different brands and models of vehicles have differences in chassis height, wheel size, etc. If the test platform cannot be height adjusted according to the specific conditions of the vehicle, then for some vehicles with high or low chassis, it may not be possible to perform accurate four-wheel alignment tests. This will limit the applicability of the test platform and reduce its efficiency. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an automotive four-wheel alignment testing platform, which solves the problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A four-wheel alignment testing platform for automobiles includes: two main bodies, each with two sliders fixedly mounted on its bottom surface; two slide rails provided on the bottom surface of each main body; the sliders and slide rails being movably fitted together; and a fixing block fixedly mounted on the bottom surface of each slide rail; and a height adjustment component: the height adjustment component is located at the bottom of the fixing block and is used to adjust the height.
[0008] By adopting the above technical solution, and by setting two main bodies that are movably fitted onto a slide rail via sliders, this design allows the main bodies to move freely on the slide rail, thereby adapting to the needs of different vehicle models and wheel spacing. This flexibility ensures that the test platform can be widely used in various types of vehicles, improving the versatility and practicality of the equipment. The height adjustment component is used to adjust the height of the entire test platform. This design allows the test platform to be precisely adjusted according to the vehicle chassis height, ensuring that the vehicle can be placed stably and accurately on the test platform, thus enabling precise four-wheel alignment testing.
[0009] Preferably, the height adjustment component includes: a base plate, which is disposed at the bottom of the fixed block, and a plurality of hydraulic telescopic rods are fixedly installed on the top surface of the base plate. The telescopic ends of the hydraulic telescopic rods are connected to the fixed block. Two rectangular slots are formed on the top surface of the base plate. Rotating slots are formed on both sides of the interior of the two rectangular slots. Synchronous motors are fixedly installed inside the four rotating slots. A bidirectional threaded column is fixedly installed between the two synchronous motors.
[0010] By adopting the above technical solution, and by connecting the telescopic end of the hydraulic telescopic rod to the fixed block, the height of the test platform can be smoothly and steplessly adjusted through precise control of the hydraulic system. The hydraulic telescopic rod has strong load-bearing capacity and stability, ensuring the stability and safety of the platform when adjusting the height. The bidirectional threaded column, driven by two synchronous motors, can rotate, thereby driving the components that cooperate with the threaded column to rise and fall. Through the precise control of the synchronous motors and the hydraulic telescopic rod by the control system, the height of the test platform can be automatically adjusted. The user only needs to input the target height value, and the system can automatically complete the adjustment process, greatly improving testing efficiency.
[0011] Preferably, the height adjustment assembly further includes: four movable blocks, which are respectively movably fitted inside the two rectangular slots, and each of the four movable blocks has a second threaded hole on one side, which is threadedly connected to a bidirectional threaded column, and a folding support frame is fixedly installed between the two movable blocks.
[0012] By adopting the above technical solution, the movable block is set so that it can move left and right as the bidirectional threaded column rotates, thereby achieving precise adjustment of the height of the test platform. Due to the stability of the threaded connection, the movable block is not prone to deviation or shaking during the adjustment process, ensuring the stability of the test platform after adjustment. At the same time, the left and right movement of the movable block drives the upward folding and fixing of the folding support frame, providing stable lifting force and support force. By adding the design of the folding support frame, the overall structural strength of the test platform after height adjustment is improved, which helps to prevent safety accidents caused by instability of the test platform.
[0013] Preferably, a drive motor is fixedly installed at the bottom of the main body, a lead screw is fixedly installed on the rotating shaft of the drive motor, and a limit block is fixedly installed at the other end of the lead screw.
[0014] By adopting the above technical solution and setting the lead screw as the key component connecting the drive motor's rotating shaft and the limit block, stable transmission performance is achieved. This ensures that the rotational force of the drive motor is transmitted smoothly, avoiding errors caused by unstable transmission. The design of the limit block ensures that the test platform maintains a stable positioning state during adjustment, avoiding test errors caused by inaccurate positioning.
[0015] Preferably, a rectangular block is fixedly installed at the bottom of the other main body, and a first threaded hole is provided on one side of the rectangular block, which is threadedly connected to a lead screw.
[0016] By adopting the above technical solution, the threaded connection between the first threaded hole and the lead screw has high strength and stability. This connection method can withstand large torque and axial force, ensuring a firm and reliable connection between the two main bodies. At the same time, it also realizes the automatic adjustment of different vehicle models and wheel spacing.
[0017] Preferably, wheel positioning grooves are provided on the top surfaces of the two main bodies, ramps are provided on both sides of the two main bodies, and anti-slip coatings are applied to one side of each of the four ramps.
[0018] By adopting the above technical solution, the wheel positioning groove design ensures that the wheel is accurately placed in the predetermined position during the test, which helps to reduce test errors and improve the accuracy of test results. The guiding effect of the wheel positioning groove enables the wheel to be quickly and accurately positioned in the test position, thereby shortening the test preparation time and improving test efficiency. The wheel positioning groove design can also reduce the friction and wear of the wheel during the test, protecting the wheel from unnecessary damage. The ramp design allows the vehicle to easily go up and down the test platform. At the same time, when encountering vehicles with excessively high or low chassis, the ramp can be flexibly replaced as needed, reducing the difficulty of operation and labor intensity. The anti-slip coating can significantly increase the friction of the ramp surface, preventing the vehicle from slipping or skidding when going up and down the test platform.
[0019] In summary, the present invention has the following main advantages:
[0020] This platform, through the flexible interlocking of sliders and rails, allows the two main components to move freely on the rails, easily adapting to the needs of different vehicle models and wheel spacings. This design not only broadens the application range of the testing platform but also highlights its high flexibility and practicality. The addition of a height adjustment component further enhances the platform's precise adjustment capabilities. This component, through the stable connection between the hydraulic telescopic rod and the fixed block, and the precise control of the hydraulic system, achieves smooth, stepless height adjustment of the testing platform. The strong load-bearing capacity and stability of the hydraulic telescopic rod ensure the platform's stability and safety during the adjustment process. Simultaneously, the bidirectional threaded column rotates under the drive of two synchronous motors, further driving the lifting and lowering of the components that cooperate with the threaded column. The control system controls the synchronous motors... With precise control of the hydraulic telescopic rod, the height adjustment of the test platform is automated. Users only need to input the target height value, and the system can automatically complete the adjustment, greatly improving testing efficiency. In terms of fine adjustment, the moving block moves left and right with the rotation of the bidirectional threaded column, thereby achieving precise control of the height of the test platform. Due to the stability of the threaded connection, the moving block is not prone to deviation or shaking during the adjustment process, ensuring the stability of the test platform after adjustment. At the same time, the left and right movement of the moving block also drives the upward folding and fixing of the folding support frame, providing stable lifting force and support force for the test platform. The design of the folding support frame not only improves the overall structural strength of the test platform after height adjustment, but also helps to prevent safety accidents caused by platform instability.
[0021] Furthermore, the lead screw, as a key component connecting the drive motor's rotating shaft and the limiting block, possesses stable transmission performance. It ensures the smooth transmission of the drive motor's rotational force, avoiding errors caused by unstable transmission. The limiting block design ensures the test platform maintains a stable positioning state during adjustment, further reducing test errors. The wheel positioning groove design is also noteworthy. It ensures the wheel is accurately placed in the predetermined position during testing, thereby reducing test errors and improving the accuracy of test results. Simultaneously, the guiding effect of the wheel positioning groove allows the wheel to be quickly and accurately positioned at the test location, shortening test preparation time and improving test efficiency. In addition, the wheel positioning groove design also reduces wheel friction and wear during testing, protecting the wheel from unnecessary damage. The ramp and anti-slip coating further enhance the convenience and safety of the test platform. The ramp allows the vehicle to easily enter and exit the test platform, reducing operational difficulty and labor intensity, while the anti-slip coating significantly increases the friction of the ramp surface, preventing the vehicle from slipping or skidding when entering and exiting the test platform.

Two main bodies 1 are movably fitted onto the slide rail 2 via sliders 9. This design allows the main bodies 1 to move freely on the slide rail 2, adapting to different vehicle models and wheel spacing requirements. This flexibility ensures the test platform can be widely used in various vehicle types, improving the equipment's versatility and practicality. The height adjustment component is used to adjust the overall height of the test platform. This design allows the test platform to be precisely adjusted according to the vehicle's chassis height, ensuring the vehicle can be placed stably and accurately on the test platform for precise four-wheel alignment testing. The height adjustment component includes: a base plate 4, which is located at the bottom of the fixed block 3. At the bottom of block 3, several hydraulic telescopic rods 401 are fixedly installed on the top surface of the base plate 4. The telescopic ends of the hydraulic telescopic rods 401 are connected to the fixed block 3. Two rectangular slots 402 are formed on the top surface of the base plate 4. Rotating slots 403 are formed on both sides of the interior of the two rectangular slots 402. Synchronous motors 404 are fixedly installed inside the four rotating slots 403. A bidirectional threaded column 405 is fixedly installed between the two synchronous motors 404. By setting the telescopic ends of the hydraulic telescopic rods 401 to be connected to the fixed block 3, and through the precise control of the hydraulic system, the height of the test platform can be smoothly and steplessly adjusted. The hydraulic telescopic rods 401 have strong load-bearing capacity and stability, which can ensure that the height can be adjusted smoothly. To ensure the stability and safety of the testing platform, the bidirectional threaded column 405, driven by two synchronous motors 404, can rotate, thereby raising and lowering the components that cooperate with the threaded column. Through precise control of the synchronous motors 404 and the hydraulic telescopic rod 401 by the control system, the height of the testing platform can be automatically adjusted. The user only needs to input the target height value, and the system can automatically complete the adjustment process, greatly improving testing efficiency. The height adjustment component also includes four moving blocks 406, which are movably fitted inside two rectangular slots 402. Each of the four moving blocks 406 has a second threaded hole 407 on one side, and the second threaded hole 407 is threaded with the bidirectional threaded column 405. A folding support frame 408 is fixedly installed between the two movable blocks 406. By setting the movable blocks 406, the movable blocks 406 can move left and right as the bidirectional threaded column 405 rotates, thereby realizing fine adjustment of the height of the test platform. Due to the stability of the threaded connection, the movable blocks 406 are not easy to deviate or shake during the adjustment process, ensuring the stability of the test platform after adjustment. At the same time, the left and right movement of the movable blocks 406 drives the folding support frame 408 to fold upward and fix, providing stable lifting force and support force. By adding the design of the folding support frame 408, the overall structural strength of the test platform after height adjustment is improved, which helps to prevent safety accidents caused by instability of the test platform.
[0029] refer to Figure 2 A drive motor 7 is fixedly mounted on the bottom of the main body 1. A lead screw 8 is fixedly mounted on the rotating shaft of the drive motor 7. A limit block 13 is fixedly mounted on the other end of the lead screw 8. By setting the lead screw 8 as a key component connecting the rotating shaft of the drive motor 7 and the limit block 13, it has stable transmission performance. It can ensure that the rotational force of the drive motor 7 is transmitted smoothly, avoiding errors caused by unstable transmission. The design of the limit block 13 can ensure that the test platform maintains a stable positioning state during adjustment, avoiding test errors caused by inaccurate positioning. A rectangular block 10 is fixedly mounted on the bottom of the other main body 1. A first threaded hole 11 is opened on one side of the rectangular block 10. The first threaded hole 11 is threadedly connected to the lead screw 8. The threaded connection between the first threaded hole 11 and the lead screw 8 has high strength and stability. This connection method can withstand large torque and axial force, ensuring that the connection between the two main bodies 1 is firm and reliable. It also realizes automated adjustment of different vehicle models and wheel spacing. The two main bodies 1 have wheel positioning grooves 12 on their top surfaces, and ramps 5 are provided on both sides of the two main bodies 1. One side of each ramp 5 is coated with an anti-slip coating 6. The wheel positioning grooves 12 ensure that the wheels are accurately placed in the predetermined positions during the test, which helps to reduce test errors and improve the accuracy of test results. The guiding effect of the wheel positioning grooves 12 allows the wheels to be quickly and accurately positioned in the test position, thereby shortening the test preparation time and improving test efficiency. The wheel positioning grooves 12 also reduce the friction and wear of the wheels during the test, protecting the wheels from unnecessary damage. The ramps 5 allow the vehicle to easily go up and down the test platform. When encountering vehicles with excessively high or low chassis, the ramps 5 can be flexibly replaced as needed, reducing the difficulty of operation and labor intensity. The anti-slip coating 6 significantly increases the friction of the ramp 5 surface, preventing the vehicle from slipping or skidding when going up and down the test platform.
[0030] Working principle: Please refer to Figures 1-3 As shown, during use, the drive motor 7 is started to drive the lead screw 8 to adjust the platform spacing according to the distance between the two vehicles. Then, the platform height is adjusted according to the vehicle chassis. The platform height is controlled by the hydraulic telescopic rod 401. After that, the synchronous motor 404 is started, which drives the moving block 406 to move in opposite directions, so that the folding support frame 408 is raised to provide lifting force and support force for the platform. Then the vehicle comes to the platform through the ramp 5. When encountering vehicles with chassis that are too high or too low, the ramp 5 can be flexibly replaced as needed. Then the front wheels of the vehicle are driven into the wheel positioning groove 12.
