Description

Technical Field

[0001] This application relates to the field of automotive repair technology, and in particular to a four-wheel rotation device for automobiles. Background Technology

[0002] With the increasing popularity of automobiles, cars have become the main means of transportation for people's daily travel in modern society. At the same time, the demand for repair and maintenance in the automotive aftermarket is also growing, with tire rotation, as a high-frequency and fundamental maintenance task, being particularly important. However, the current mainstream tire rotation process still heavily relies on traditional manual operation methods, which are not only inefficient but also physically demanding on operators, urgently requiring optimization and upgrading through technological means. Utility Model Content

[0003] To facilitate the rapid rotation of four wheels of a car, this application provides a four-wheel rotation device for a car.

[0004] The automotive four-wheel rotation device provided in this application adopts the following technical solution:

[0005] A four-wheel rotation device for automobiles includes a car carrier with casters at the bottom and two lifting components on the car carrier. Each lifting component has a lifting plate at its lifting end, and the lifting plate has a shelf for placing tires. The lifting components drive the lifting plate to move up and down, and the lifting distance of the lifting plate is greater than the diameter of the tire.

[0006] By adopting the above technical solution, when multiple vehicles need to be rotated (four wheels in total), the trolley bracket is moved. The trolley bracket moves two lifting components, a lifting plate, and a storage rack. The first lifting component raises the lifting plate, which in turn raises the storage rack, placing the first tire inside the storage rack. After the first tire is removed, the lifting component lowers the first tire. Then, the trolley bracket is moved to the second tire position. The second lifting component raises the storage rack, and after the second tire is removed, the second lifting component lowers the second tire. Finally, the first lifting component raises the first tire, thus quickly completing the tire rotation.

[0007] Preferably, the lifting assembly includes a scissor lift frame and a drive unit. The bottom of the scissor lift frame is connected to the trolley bracket, and the top of the scissor lift frame is connected to the lifting plate. The drive unit is disposed inside the scissor lift frame and is used to drive the scissor lift frame to extend and retract.

[0008] By adopting the above technical solution, the driving component causes the scissor lift to extend and retract, and the scissor lift to move the lifting plate smoothly up and down.

[0009] Preferably, the scissor lift frame is provided with a telescopic guide rod, and the two ends of the telescopic guide rod are rotatably connected to the scissor lift frame.

[0010] By adopting the above technical solution, the telescopic guide rod extends and retracts synchronously when the scissor lift telescopic frame extends and retracts. The telescopic guide rod guides and positions the deformation of the scissor lift telescopic frame, thereby further improving the stability of the lifting platform.

[0011] Preferably, one end of the upper and lower sides of the scissor lift frame is rotatably connected to the lifting plate and the trolley bracket, respectively. Both the lifting plate and the trolley bracket are provided with roller tracks. The other end of the upper and lower sides of the scissor lift frame is rotatably provided with rollers, and the two rollers are rolled in the two roller tracks.

[0012] By adopting the above technical solution, when the scissor lift telescopic frame extends and deforms, it drives two rollers to move within two raceways, thereby further improving the stability of the lifting platform.

[0013] Preferably, a slide rail is provided on the top wall of the lifting plate, a slider is slidably arranged on the slide rail, the shelf is fixedly arranged on the slider, and rollers are rotatably arranged on both opposite sides of the shelf.

[0014] By adopting the above technical solution, when the lifting plate moves the shelf upward and contacts the tire, the tire will first contact a roller. As the shelf continues to rise, the roller rolls on the tire and drives the shelf to slide on the slide rail, thereby automatically adjusting the position of the shelf so that both rollers abut against the supporting tire.

[0015] Preferably, limit strips are fixedly provided on both sides of the shelf along the direction perpendicular to the line connecting the two rollers.

[0016] By adopting the above technical solution, when the tire is placed on the two rollers, the two limiting strips on the shelf abut and limit the tire from both sides, which improves the stability of the tire placement.

[0017] Preferably, the lifting plate is provided with a stop bar, which is located on one side of the shelf.

[0018] By adopting the above technical solution, after the tire is disassembled, it rests against the stop bar, thereby reducing the possibility of the tire falling off the shelf.

[0019] Preferably, the trolley bracket is provided with a handrail.

[0020] By adopting the above technical solution, the handrail facilitates the movement of the trolley bracket.

[0021] Preferably, a hanging plate is fixedly installed on the handrail.

[0022] By adopting the above technical solution, a hanging plate is used to place auxiliary tools when changing tires, thus facilitating tire replacement.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Using two lifting components, when multiple cars need to be rotated, the trolley bracket is moved. The trolley bracket moves the two lifting components, the lifting plate, and the storage rack. The first lifting component raises the lifting plate, which in turn raises the storage rack, so that the first tire is located in the storage rack. After the first tire is removed, the lifting component moves the first tire down. Then the trolley bracket is moved to the second tire, and the second lifting component raises the storage rack. After the second tire is removed, the second lifting component moves the second tire down, and the first lifting component raises the first tire again, thus quickly completing the tire rotation.

[0025] 2. With the help of the telescopic guide rod, the telescopic guide rod extends and retracts synchronously when the scissor lift platform deforms. The telescopic guide rod guides and positions the deformation of the scissor lift platform, thereby further improving the stability of the lifting platform.

[0026] 3. Through the slider and roller, when the lifting plate moves the shelf upward and contacts the tire, the tire will first contact one of the rollers. As the shelf continues to rise, the roller rolls on the tire and drives the shelf to slide on the slide rail, thereby automatically adjusting the position of the shelf so that both rollers abut against the supporting tire.

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses a four-wheel rotation device for automobiles.

[0034] Reference Figure 1 A four-wheel tire changing device for automobiles includes a trolley bracket 1, with casters 2 installed at each of the four corners of the bottom of the trolley bracket 1. A handle 14 is fixedly installed on one side of the top wall of the trolley bracket 1, and a scraper is fixedly installed on the handle 14. By pushing the trolley bracket 1 with the handle 14, the trolley bracket 1 can move freely under the action of the four casters 2, and auxiliary tools for changing tires are hung on the hanging plate 15.

[0035] Two lifting components 3 are installed side by side on the car bracket 1. Each lifting component 3 has a lifting plate 4 installed on its top lifting end. The lifting components 3 can drive the lifting plate 4 to move smoothly up and down, and the lifting height of the lifting plate 4 is greater than the diameter of the tire.

[0036] Specifically, the lifting assembly 3 includes a scissor lift telescopic frame 31 and a drive component 32. One side of the upper and lower ends of the scissor lift telescopic frame 31 is rotatably mounted on the lifting plate 4 and the trolley bracket 1, respectively. Two rollers 8 are rotatably mounted on the other side of the upper and lower ends of the scissor lift telescopic frame 31. Two roller tracks 7 are symmetrically fixedly installed inside both the lifting plate 4 and the trolley bracket 1. The two rollers 8 at the bottom of the scissor lift telescopic frame 31 are rolled within the two roller tracks 7 of the trolley bracket 1, and the two rollers 8 at the top of the scissor lift telescopic frame 31 are rolled within the two roller tracks 7 of the lifting plate 4.

[0037] Both ends of the drive unit 32 are rotatably connected to the scissor lift frame 31. In this application, the drive unit 32 can be an electric telescopic rod. Telescopic guide rods 6 are installed on both sides of the scissor lift frame 31 located on the drive unit 32, and both ends of the telescopic guide rods 6 are rotatably connected to the scissor lift frame 31.

[0038] The drive unit 32 drives the scissor lift frame 31 to deform, thereby driving the lifting plate 4 to rise and fall smoothly. To ensure motion accuracy, two telescopic guide rods 6 connected to the scissor lift frame 31 provide guidance and positioning; at the same time, the rollers 8 installed on the scissor lift frame 31 roll in the raceway 7, jointly constraining lateral displacement, thereby significantly improving the stability of the scissor lift frame 31.

[0039] The lifting plate 4 is hollow. Two slide rails 9 are symmetrically fixed on the top wall of the lifting plate 4 along its own width direction. Two sliders 10 are slidably installed on each slide rail 9, and a shelf 5 is fixedly installed on the top of the four sliders 10.

[0040] The shelf 5 is hollow, and rollers 11 are rotatably installed at both ends of the shelf 5 in the length direction. Limiting strips 12 are fixedly installed on the two opposite inner side walls of the shelf 5 in the width direction. A stop bar 13 is fixedly installed on the lifting plate 4 on the side of the shelf 5 near the handrail 14.

[0041] When the lifting plate 4 raises the shelf 5, the rollers 11 on the shelf 5 contact the tire. As the shelf 5 continues to rise, the rollers 11 roll on the tire surface, pushing the shelf 5 along the slide rail 9, thus achieving automatic alignment and ensuring that the two rollers 11 evenly support the tire. Subsequently, the limiting strips 12 on both sides of the shelf 5 restrain the tire's sidewalls. After disassembly, the rear stop bar 13 prevents the tire from falling, ensuring stability and safety throughout the operation.

[0042] The implementation principle of a four-wheel rotation device for automobiles according to an embodiment of this application is as follows: First, the integrated mobile cart carrier 1 is moved to the target workstation, and the first lifting component 3 is activated. The lifting component 3 drives the rack 5 to rise, precisely enclosing the first tire to be removed. After the tire is removed, the lifting component 3 lowers the tire safely. Subsequently, the mobile cart carrier 1 is moved to the second tire workstation, where the second lifting component 3 performs the same lifting and removal operation. After the second tire descends, the first lifting component 3 raises the removed first tire again, thus efficiently completing the swapping of the two tires. This sequence is repeated until the four-wheel rotation is completed.

[0043] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
