Description

Technical Field

[0001] This utility model belongs to the field of automotive repair technology, specifically relating to a vehicle positioning device for a car lift. Background Technology

[0002] With the continuous development of society, people's demand for cars is increasing, leading to the continuous growth of the auto repair industry. In the auto repair process, a car lift is generally used to lift the car so that the chassis can be inspected and repaired. A typical car lift consists of a lifting assembly and a lifting platform mounted on the assembly. In use, the car is driven onto the lifting platform, and then the lifting assembly raises both the platform and the car, allowing for undercarriage repairs.

[0003] Traditionally, after a car is driven onto a car lift, to prevent the car from rolling off the lift during repairs due to a malfunctioning or improperly engaged handbrake, mechanics typically place four bollards next to the lift. Once the car is on the lift, the mechanics place the bollards one by one at each of the four wheels to prevent the car from sliding off. After the repairs are complete, the mechanics remove the bollards one by one from the lift. This process requires repeated placement and removal of the bollards during each repair, making it very cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle positioning device for a car lift, which can quickly control the blocks to automatically block the wheels of a car, making operation more convenient and eliminating the need for maintenance personnel to place the blocks at the corresponding positions of each tire, thereby improving the efficiency of car maintenance via the lift.

[0005] The specific technical solution adopted in this utility model is as follows: A vehicle positioning device for a car lift includes two platforms installed on the top of the lift platform. A connecting rod is fixedly installed between the two platforms near one side.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0018] Please see the appendix Figures 1 to 10 As shown, this utility model provides a vehicle positioning device for a car lift, including two platforms 1 installed on the top of the lift platform. A connecting rod 2 is fixedly installed between the two platforms 1 near one side. A power component is installed on one side of the connecting rod 2, and an adjustment component is installed on the power component. A first through groove 8 is opened in the middle of the top of the platform 1, penetrating the interior of the platform 1. A sliding rod 10 is fixedly installed on the inner wall of the first through groove 8. A connecting block 9 is fixedly installed at one end of the sliding rod 10. The connecting block 9 is fixedly connected to the side wall of the first through groove 8. A sliding sleeve 7 is slidably connected to the outer wall of the sliding rod 10 at a position corresponding to the adjustment component. The adjustment component extends into the interior of the platform 1 and is fixedly connected to the sliding sleeve 7. A lifting component is installed at the top of the sliding sleeve 7. A moving stop 17 is fixedly installed at the top of the lifting component and above the platform 1. A fixed stop 18 is fixedly installed on the side of the top of the platform 1 away from the moving stop 17.

[0019] With the above structure, when the car is driven to the point where the two tires are in contact with the fixed stop block 18, the power component can be activated, causing the power component to move the adjustment component, which in turn causes the sliding sleeve 7 to move the lifting component. The lifting component then moves the moving stop block 17, causing the moving stop block 17 to gradually approach the other two tires of the car until it is in contact with them. This allows the moving stop block 17 and the fixed stop block 18 to block and position the tires, preventing the car from falling off the lift during maintenance and improving safety. Furthermore, the above adjustment method allows the moving stop block 17 to be quickly adjusted to a suitable position to accommodate vehicles of different lengths. The adjustment of the moving stop block 17 is also more convenient, eliminating the need for maintenance personnel to place each stop block individually on the tires, making the adjustment of the moving stop block 17 simpler and faster, thereby improving the efficiency of car maintenance via the lift.

[0020] In a preferred embodiment, please refer to Figure 1 and Figure 3 The power assembly includes a motor compartment 4, which houses a motor. A threaded rod 3 is fixedly mounted on the output end of the motor. The end of the threaded rod 3 away from the motor compartment 4 is rotatably connected to a connecting rod 2. The bottom of the motor compartment 4 is flush with the bottom of the platform 1.

[0021] In this embodiment, when it is necessary to adjust the position of the moving stop 17, the motor inside the motor compartment 4 can be started. The motor drives the threaded rod 3 to rotate, the threaded rod 3 drives the adjustment component to move, and the adjustment component drives the sliding sleeve 7 to slide on the outer wall of the slide rod 10, thereby causing the slide rod 10 to drive the lifting component to move, and the lifting component drives the moving stop 17 to move, thereby realizing the adjustment of the position of the moving stop 17.

[0022] Secondly, please refer to again Figures 3 to 5 The adjustment component includes an internally threaded sleeve 5, which is threaded to the outer wall of the threaded rod 3 on the side near the motor compartment 4. Moving rods 6 are symmetrically arranged on both sides of the internally threaded sleeve 5. A second through groove 11 is provided on the opposite side of the two platforms 1 and at the position corresponding to the moving rod 6. The moving rod 6 is slidably connected to the second through groove 11. The second through groove 11 is connected to the first through groove 8. The moving rod 6 extends through the second through groove 11 into the interior of the first through groove 8 and is fixedly connected to the sliding sleeve 7.

[0023] In the above structure, when the threaded rod 3 rotates, the threaded rod 3 drives the internal threaded sleeve 5 to move along the threaded rod 3. The internal threaded sleeve 5 moves the moving rod 6 and the sliding sleeve 7. During the movement, the moving rod 6 slides inside the second through groove 11, and the sliding sleeve 7 slides along the slide rod 10, thereby causing the sliding sleeve 7 to drive the lifting assembly and the moving stop 17 to move, so that the moving stop 17 moves to the appropriate position.

[0024] Secondly, please refer to the following as well. Figure 5 and Figure 7 The lifting assembly includes a connecting sleeve 12, which is fixedly connected to the top of the sliding sleeve 7. A sliding column 13 is slidably connected inside the connecting sleeve 12. The top of the sliding column 13 extends to the outside of the connecting sleeve 12 and is fixedly connected to the moving stop 17. Adjustment components are fixedly connected to both sides of the sliding column 13.

[0025] In the above structure, when the sliding sleeve 7 moves, the sliding sleeve 7 drives the connecting sleeve 12 and the sliding column 13 to move, thereby causing the sliding column 13 to drive the moving stop 17 to move, thus realizing the adjustment of the position of the moving stop 17.

[0026] In a preferred embodiment, please refer to Figure 5 and Figure 10 The adjustment assembly includes two displacement rods 15, which are fixedly connected to the sides of the sliding column 13 near the bottom. Limiting grooves 14 are provided on both sides of the connecting sleeve 12 at positions corresponding to the displacement rods 15. The limiting grooves 14 are adapted to the displacement rods 15, and the end of the limiting groove 14 away from the sliding column 13 extends through the limiting groove 14 to the outside of the connecting sleeve 12. An adjustment groove 16 is provided on the side wall of the first through groove 8 at a position corresponding to the displacement rods 15. The end of the displacement rod 15 away from the sliding column 13 extends into the interior of the adjustment groove 16 and is slidably connected to the adjustment groove 16. The end of the adjustment groove 16 connected to the displacement rod 15 is gradually inclined upward and then extends horizontally.

[0027] In this embodiment, during the movement of the sliding column 13, the sliding column 13 drives the displacement rod 15 to move. At this time, the end of the displacement rod 15 away from the sliding column 13 slides inside the adjustment groove 16. Since the initial position of the adjustment groove 16 is inclined upward, when the displacement rod 15 just begins to slide along the adjustment groove 16, the displacement rod 15 drives the sliding column 13 to gradually move upward. At this time, the sliding column 13 slides inside the connecting sleeve 12, and the displacement rod 15 slides inside the limiting groove 14. During the upward movement of the sliding column 13, the sliding column 13 drives the moving block 17 to rise upward. When the displacement rod 15 slides to the position where the adjustment groove 16 is in a horizontal state, the sliding column 13 and the moving block 17 no longer rise but continue to move towards the tire. Thus, the raised moving block 17 blocks and positions the tire of the car, making the blocking and positioning of the tire of the car by the moving block 17 more stable, further preventing the car from moving during maintenance on the lift, avoiding the car from falling from the lift, and further improving the safety during maintenance.

[0028] Secondly, please refer to again Figure 1 The moving stop 17, displacement rod 15, connecting sleeve 12, sliding column 13, sliding sleeve 7 and slide rod 10 are all made of aluminum alloy.

[0029] In this embodiment, the durability of the aforementioned components is improved.

[0030] The working principle of this utility is as follows: During use, a car can be driven onto the platform 1 located on the lifting platform, with the car's tires positioned on two platforms 1 respectively, simultaneously contacting the fixed stops 18. After the car is parked, the motor inside the motor compartment 4 can be started, causing the motor to drive the threaded rod 3 to rotate. During the rotation of the threaded rod 3, the threaded rod 3 drives two moving rods 6 to move along the threaded rod 3 via the internal threaded sleeve 5. The sliding sleeve 7 slides along the moving rods 6 on the sliding rod 10, thereby causing the sliding sleeve 7 to drive the moving stop 17 to move via the connecting sleeve 12 and the sliding column 13. This causes the moving stop 17 to gradually approach the other two not-contacted stops 18. The fixed stop block 18 contacts the tires and gradually contacts both tires, thereby positioning the car through the cooperation of the moving stop block 17 and the fixed stop block 18. This prevents the car from falling off the lift during maintenance, improving safety during maintenance. At the same time, this adjustment method can automatically and quickly adjust the position of the moving stop block 17 to match the size of the car, making the positioning operation of the car more convenient. It eliminates the need for maintenance personnel to place the stops one by one in the corresponding positions of the tires, thereby improving the efficiency of car maintenance through the lift. When positioning is completed, the lift can be raised to inspect the car chassis. During the movement of the sliding sleeve 7, which drives the connecting sleeve 12 and the sliding column 13, the sliding column 13 drives the displacement rod 15 to slide inside the adjustment groove 16. Since the end of the adjustment groove 16 near the displacement rod 15 is inclined upward, when the displacement rod 15 first slides inside the adjustment groove 16, the displacement rod 15 gradually moves upward. The displacement rod 15 drives the sliding column 13 to slide upward inside the limiting groove 14, thereby causing the sliding column 13 to drive the moving block 17 to move upward. This causes the moving block 17 to rise a certain distance relative to the platform 1. As the displacement rod 15 slides to the position where the adjustment groove 16 extends horizontally, the moving block 17 stops rising but still moves towards the tire to block and position it. Because the moving block 17 is raised a certain distance, the blocking and positioning of the tire by the moving block 17 is more secure, further preventing the car from moving during maintenance on the lift and avoiding the car from falling off the lift, thus further improving the safety during maintenance.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model shall be implemented according to conventional methods in the art unless otherwise specified or limited.
