Description

Technical Field

[0001] This invention relates to the field of automotive repair lifting equipment technology, specifically to a lifting device for automotive repair with multi-directional adjustment. Background Technology

[0002] A car lift is a device used to lift cars during the automotive repair process. When a car is driven to the lift station, it can be raised to a certain height by manual operation to facilitate repairs. Car lifts play a very important role in automotive repair and maintenance, and nowadays all repair shops are equipped with car lifts; they are essential equipment for automotive repair shops.

[0003] Publication No. CN215711437U discloses a lifting device for automobile repair, including a scissor lift frame and a top support plate disposed at the top of the scissor lift frame. The device is characterized in that: two bottom slide seats are slidably installed at the bottom of the top support plate, and the bottom slide seats have internal sliding grooves. An internal sliding base block is disposed inside the internal sliding groove, and a limit stop block is fixed to the top of the internal sliding base block. A strip-shaped sliding opening corresponding to the limit stop block is formed on the surface of the top support plate, and the top of the limit stop block extends through the strip-shaped sliding opening to the top of the top support plate. A base rod is fixed to the front surface of the internal sliding base block, and a rod slide corresponding to the base rod is formed on the surface of the bottom slide seat. The top of the base rod extends through to the front surface of the bottom slide seat, and a pull ring and a cylindrical spring are sleeved on the top of the base rod. Side clamping plates are symmetrically fixed on both sides of the pull ring, and the side clamping plates... A rectangular block is fixed on the inner side. The front surface of the bottom slide seat has two rectangular slots symmetrically opened on both sides of the rod slide, corresponding to the rectangular block. The rectangular block is locked inside one of the rectangular slots. This device effectively improves the safety of the car scissor lift in actual use, and the limit block is easy to retract later. However, in actual use, due to the different chassis heights of different brands of vehicles, high chassis vehicles can be quickly lifted by supporting the vehicle's support points. However, low chassis vehicles are prone to tipping over during lifting due to their relatively forward or rearward center of gravity. Usually, other equipment is needed to assist in lifting them to ensure normal lifting. This method obviously has low applicability and low lifting efficiency. The applicability of existing equipment for lifting vehicles for maintenance has room for further improvement. Summary of the Invention

[0033] Working principle: The car is driven on the top of the support device 3 via the inclined plate 30. At this time, the two drive compartments 31 are located on the left and right sides of the car chassis, respectively. Initially, the four fixed compartments 420 are far apart from each other, the first bevel gear 322 and the second bevel gear 450 are not in contact with each other, and the first gear 321 and the second gear 330 are meshed. The spray plate 424 is exposed on the top of the adjusting compartment 42. The first linear drive assembly 11 is activated by the control center 10. The activation of the first linear drive assembly 11 pushes out and moves the first output rod 12. The first output rod 12 moves, driving the auxiliary device 4 to move until the auxiliary device 4 moves to the chassis of the car. At this time, all four spray plates 424 are at the support points at the bottom of the car chassis. The control center 10 activates the first rotary drive assembly 32, which drives the rotating shaft 320 to rotate. The rotation of the rotating shaft 320 drives the first gear 321 and the first bevel gear 322 to rotate. The rotation of the first gear 321 drives the second gear 330 to rotate. The rotation of the second gear 330 is transmitted through the first shaft 33. The rotating disk 331 rotates, which in turn rotates the movable rod 332. The movable rod 332 then causes the return plate 333 to reciprocate linearly. The movement of the return plate 333 causes the movable plate 334 to move, which in turn causes the piston plate 335 to reciprocate linearly within the conveying chamber 34. Initially, the piston plate 335 is located at the end of the conveying chamber 34 closest to the extraction pipe 341, causing a reciprocating phenomenon of decreasing and increasing air pressure inside the conveying chamber 34. When the air pressure inside the conveying chamber 34... When the pressure decreases, the water inside the storage chamber 343 enters the conveying chamber 34 through the extraction pipe 341. When the air pressure inside the conveying chamber 34 increases, the water inside the conveying chamber 34 is conveyed to the spray plate 424 through the conveying pipe 342. The spray plate 424 sprays the water onto the chassis of the car, thereby cleaning the chassis of the car before lifting. This allows the device to clean the chassis of the car during the lifting process, avoiding the impact of debris on the chassis on subsequent lifting and maintenance, and improving the applicability of the device for lifting different chassis. After the above steps are completed, the second rotary drive assembly 430 is activated by the control center 10. The activation of the second rotary drive assembly 430 drives the first screw 431 to rotate. The rotation of the first screw 431 drives the movable block 432 to move. The movement of the movable block 432 drives the fixed chamber 420 to move through the slide rod 433 and the push plate 434 until the fixed chamber 420 blocks the spray plate 424 and the buffer plate on the top of the fixed chamber 420 is closed. At point 422, the lifting device 1 is in close contact with the support point of the car chassis. Then, the lifting device 1 is activated by the control center 10. This drives the two auxiliary devices 4 upwards via the first linear drive assembly 11 and the first output rod 12. The movement of the two auxiliary devices 4 moves the car upwards, thus completing the lifting process. Next, the electric turntable 440 is activated by the control center 10. Initially, the third linear drive assembly 441 and the adjustment chamber 42 are parallel. The electric turntable 440 is activated, driving the third linear drive assembly 441 to rotate via the rotating component 44 until the first linear drive assembly 441 rotates. The three linear drive assembly 441 forms a 90-degree angle with the adjustment chamber 42. Then, the control center 10 activates the third linear drive assembly 441 to push out and move the third output rod 442. The movement of the third output rod 442 pushes out and moves the support plate 443 until the support plate 443 is tightly attached to the top of the support device 3, so that it provides an additional support force to the car. This avoids the lifting device 1 bearing the weight of the car throughout the lifting process, which would lead to unstable support of the device and easy rollover of the car. This improves the stability of the lifting device and makes it easier for users to use. The above steps describe the lifting mechanism for high-chassis vehicles. When the vehicle to be lifted for repair is a low-chassis vehicle, due to the forward or backward tilt of the center of gravity, the control center 10 activates the first linear drive assembly 11 and the second linear drive assembly 310. The first linear drive assembly 11, similarly described above, delivers the two adjustment chambers to the chassis of the low-chassis vehicle. The second linear drive assembly 310 activates, pushing out and moving the second output rod 311. The movement of the second output rod 311 drives the first rotary drive assembly 32, the rotating shaft 320, the first gear 321, and the first bevel gear 322 to move upwards as a whole, until the first bevel gear 322 engages with the... The second bevel gear 450 at the vehicle chassis engages, and the first gear disk 321 and the second gear disk 330 disengage. Then, the control center 10 activates the first rotary drive assembly 32. The activation of the first rotary drive assembly 32 drives the first gear disk 321 and the first bevel gear 322 to rotate via the rotating shaft 320. The rotation of the first bevel gear 322 drives the second bevel gear 450 to rotate. The rotation of the second bevel gear 450 drives the second connecting member 452 to move via the second screw 451. The movement of the second connecting member 452 causes the two second adjusting arms 453 to rotate. Simultaneously, the rotation of the second adjusting arms 453 drives the movable arm 454 to move at the adjusting chamber 42. The sliding motion continues as the movable arm 454 moves a certain distance, causing the first adjusting arm 410 to rotate at the first connecting member 41 until the two first adjusting arms 410 are in a straight line. At this point, the control center 10 activates the two hydraulic jacks 5, which lift the car a certain distance. Then, the user can activate the first linear drive assembly 11 through the control center 10 to retract and move part of the first output rod 12, and reset the two auxiliary devices 4 a certain distance until the four fixed compartments 420 are respectively located at the four tires of the car. Then, the lifting device 1 drives the auxiliary devices 4 and the fixed compartments through the first linear drive assembly 11 and the first output rod 12. The device moves upward at 420, simultaneously clamping the car's tires. Under the action of the lifting equipment 1, it lifts and repairs low-chassis vehicles. After lifting, the device can still provide secondary support for the car. This device can lift vehicles with different chassis heights. The lifting method for high-chassis vehicles is more efficient due to the smaller number of devices activated, resulting in relatively lower energy consumption. Conversely, the lifting method for low-chassis vehicles is relatively slower due to the larger number of devices activated, resulting in higher energy consumption, but the lifting is more stable. This process also improves the stability of lifting and repairing vehicles, enhancing the applicability of the device for lifting different chassis. In the above process, when the length of the car chassis is different, resulting in different support points for high-chassis cars and different tire positions for low-chassis cars, the user can adjust the position of the fixed chamber 420 by activating the second rotary drive component 430 in the above steps. This allows the device to be adapted to lift cars of various sizes and models, improving the applicability of the device for lifting different chassis and making it easier for users to use.
