[0003] A lifting mechanism, as announced in Chinese Patent Publication No. CN210338122U, comprises: a connecting rod; a sliding mechanism; a rotating mechanism; a guiding mechanism; and a fixing mechanism. The fixing mechanism is fixedly connected to the connecting rod and includes a protective shell, a baffle, a gear, a long rod, a fixed plate, a gear, and a rotating column. The protective shell is fixedly connected to the side wall of the connecting rod, the rotating column is rotatably connected to the protective shell, the gear is sleeved on the rotating column, the long rod is slidably connected to the protective shell, the gear is fixedly connected to the side wall of the long rod and meshes with the gear, the baffle is fixedly connected to the top end of the long rod, and the fixed plate is fixedly connected to the bottom end of the long rod; a rope; and a hook, which is fixedly connected to the bottom end of the fixed plate.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0024] like Figures 1 to 3 As shown, a lifting device adaptable to multiple vehicle body sizes includes a base plate 1. Lifting base plates 2 are slidably connected to both sides of the base plate 1. Two sliding grooves 3 are formed on the base plate 1 and are symmetrically distributed along the center of the base plate 1. Sliding connection mechanisms for driving the lifting base plates 2 to slide are respectively provided in the two sliding grooves 3. Sliding drive mechanisms are provided on the two sliding connection mechanisms. A lifting guide mechanism is provided on each of the two lifting base plates 2. Lifting plates 23 are slidably connected to the lifting guide mechanisms. Hooks 4 are provided at the bottom of each lifting plate 23. A set of vehicle body fixing components is provided on both sides of each lifting plate 23. The two lifting plates 23 are lifted and lowered by the lifting drive mechanism, which is located on the base plate 1.

[0025] In use, the base plate 1 provides support for the entire device. According to the size of the vehicle body, the sliding drive mechanism is activated, driving the two sets of sliding connection mechanisms to slide in the corresponding sliding grooves 3. This causes the lifting base plate 2 to move on the base plate 1, thereby adjusting the distance between the two lifting base plates 2 to accommodate the width requirements of different vehicle body sizes. The lifting drive mechanism then starts working, driving the two lifting plates 23 to move up and down along the direction of the lifting guide mechanism, so that the hooks 4 and the vehicle body fixing components can reach the appropriate positions for lifting or fixing the vehicle body. When the lifting plate 23 is raised to the appropriate height, the hooks 4 at the bottom of the lifting plate 23 can be used to hook specific parts of the vehicle body. At the same time, the vehicle body is further fixed by the vehicle body fixing components on both sides of the lifting plate 23 to ensure that the vehicle body remains stable during the lifting process.

[0026] The sliding connection mechanism includes a sliding link 5, one end of which is rotatably connected to a connecting shaft 6, and the other end is rotatably connected to a sliding drive mechanism. Connecting bases 7 are provided at both ends of the connecting shaft 6, and the connecting bases 7 are located on the top of the lifting base plate 2. The sliding drive mechanism includes a sliding cylinder 8, and a sliding joint 9 is provided on the piston rod of the sliding cylinder 8. The sliding joint 9 is rotatably connected to two sliding links 5, and the sliding cylinder 8 is installed and fixed by a sliding seat 10.

[0027] Depending on the size of the vehicle body, the sliding cylinder 8 starts to work. The piston rod of the sliding cylinder 8 extends or retracts, transmitting linear force to the sliding joint 9. The sliding joint 9 is rotatably connected to the sliding connecting rod 5, causing the sliding connecting rod 5 to rotate accordingly. The rotation of the sliding connecting rod 5 can drive the connecting base 7 to make corresponding linear displacement. The linear displacement of the connecting base 7 can drive the lifting base plate 2 to move to adapt to different vehicle body sizes.

[0028] The lifting guide mechanism includes a lifting slide rail 11, which is located on one side of the lifting plate 23. Several lifting slides 12 are provided on the lifting slide rail 11, and the lifting slides 12 are bolted to the lifting plate 23.

[0029] Driven by the lifting drive mechanism, when the lifting plate 23 is lifted, the lifting slide 12 will slide up and down along the lifting slide rail 11. The lifting slide rail 11 can restrict the movement direction of the lifting slide 12, so that it can only move in a straight line along the extension direction of the slide rail, thereby ensuring that the lifting plate 23 will not deviate or shake during the lifting process, and ensuring the accuracy and stability of the lifting movement.

[0030] The vehicle body fixing assembly includes a fixing cylinder 13, a fixing joint 14 is provided on the piston rod of the fixing cylinder 13, a fixing arm 15 is rotatably connected to the fixing joint 14, an electromagnetic block 16 is provided on the fixing arm 15, and the fixing cylinder 13 is fixed to the lifting plate 23 by bolts through a fixing seat 17.

[0031] When the hook 4 is attached to a specific part of the vehicle body, the fixed cylinder 13 serves as the driving source. The piston rod of the fixed cylinder 13 extends or retracts, transmitting force to the fixed connector 14. The fixed connector 14 drives the fixed arm 15 to rotate accordingly. The rotation of the fixed arm 15 can drive the electromagnetic block 16 to rotate accordingly, further reinforcing the vehicle body so that it will not shake or shift during the lifting process, or after rising to the designated position, the vehicle body is relaxed accordingly.

[0032] The lifting drive mechanism includes a lifting cylinder 18. A lifting connecting plate 19 is provided on the piston rod of the lifting cylinder 18. Lifting connecting sleeves 20 are provided at both ends of the lifting connecting plate 19. Lifting connecting rods 21 are provided on both lifting connecting sleeves 20. The two lifting connecting rods 21 are respectively fixedly connected to a lifting plate 23. The lifting cylinder 18 is bolted to the base plate 1 by a lifting seat 22. The top of the lifting seat 22 is bolted to the sliding seat 10.

[0033] The two lifting plates 23 are connected by the lifting connecting plate 19, the lifting connecting sleeve 20, and the lifting connecting rod 21. A single lifting cylinder 18 can simultaneously drive the two lifting plates 23 to perform corresponding lifting and lowering operations. The lifting cylinder 18 is the power source, and its piston rod extends or retracts to transmit force to the lifting connecting plate 19. The lifting connecting plate 19 then transmits force to the lifting connecting rod 21, which in turn drives the two lifting plates 23 to rise or fall simultaneously, thereby performing corresponding lifting and lowering operations on the vehicle body.

[0034] Working principle: Based on the dimensions of the vehicle body, the sliding cylinder 8 is activated, causing the sliding connecting rod 5 to rotate via the sliding joint 9. The rotation of the sliding connecting rod 5 drives the connecting base 7 to make a corresponding linear displacement. The linear displacement of the connecting base 7 drives the lifting base plate 2 to move, thereby adjusting the distance between the two lifting base plates 2. After adjustment, the lifting cylinder 18 starts working, driving the two lifting plates 23 to move up and down via the lifting connecting plate 19, lifting connecting sleeve 20, and lifting connecting rod 21, so that the hook 4 can reach the appropriate position and hook onto a specific part of the vehicle body. At the same time, the fixed cylinder 13 serves as the power source, transmitting force to the fixed joint 14. The fixed joint 14 drives the fixed arm 15 to rotate accordingly. The rotation of the fixed arm 15 drives the electromagnetic block 16 to rotate accordingly, further reinforcing the vehicle body and ensuring the stability of the vehicle body during the lifting process.
