Description

Technical Field

[0001] This invention relates to the field of automotive repair technology, specifically to an automotive repair tilting device. Background Technology

[0002] In automotive repair, operations such as chassis inspection, parts replacement, and fluid draining often require technicians to access the underside of the vehicle. Traditionally, this is achieved using trenches or simple lifting devices. However, trenches require digging trenches in the ground, which is not only costly but also occupies a fixed area and lacks flexibility. While existing lifting devices can raise the vehicle to a certain height, they typically only offer vertical lifting and cannot be tilted at multiple angles as needed. Technicians still have to work in uncomfortable postures, such as looking up or bending over, which can easily lead to neck and lumbar spine fatigue and injury over time.

[0003] Furthermore, some existing tilting devices are inadequate in securing the vehicle after it has tilted, making it prone to slipping or shifting while tilted, posing a safety hazard. While some devices do offer some tilting capability, they lack the flexibility to adjust the position of the blocking mechanism according to the wheelbase and track width of different vehicle types, resulting in poor adaptability. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention discloses an automotive repair tilting device. This device uses a base frame as its supporting foundation, which cooperates with an integrated lifting mechanism to smoothly lift the entire device vertically. The upper surface of the base frame has upwardly protruding uprights at the middle positions of its front and rear ends, with mounting holes on the uprights. A middle frame is inserted into these mounting holes via a centrally formed shaft on its front and rear sides, thus rotatably mounted above the base frame. Shafts are fixed to the rear ends of the left and right sides of the base frame, and two side plates are rotatably mounted on these shafts, allowing the side plates to swing up and down around their rear ends. A transition ramp is integrally connected to the front end of each side plate, extending downwards at an angle to facilitate vehicles driving onto the side plates from the ground.

[0005] As a preferred embodiment of the present invention, to achieve active tilt control of the side panel, front hydraulic lifters are fixed at the two front corners of the underframe, with their output ends supported on the front side of the side panel's bottom. The extension and retraction of the piston rod drives the front end of the side panel to rise and fall. Simultaneously, a shaft is provided at the rear end of the side panel's outer side, rotatably connected to an end block. The end block is placed on an L-shaped support plate, the bottom of which is connected to the output ends of the rear hydraulic lifters fixed at the two rear corners of the underframe. Through the independent or coordinated action of the two sets of hydraulic lifters, the side panel can be tilted in various positions, such as front-high-rear-low or rear-high-front-low, meeting the vehicle angle requirements of different maintenance procedures.

[0006] As a preferred embodiment of the present invention, in terms of vehicle positioning and anti-slip, each side plate has a cross-shaped sliding groove and a rear side groove respectively formed on the upper surface. A cross-shaped slider adapted to the shape is installed within the cross-shaped sliding groove. This slider can move back and forth along the groove. Blind holes are formed on the outer wall of its horizontal portion, while multiple through holes are distributed along the length of the outer wall of the cross-shaped sliding groove. By inserting a positioning pin into the through holes and blind holes, the cross-shaped slider can be locked in the desired position. A front stop plate is fixed to the cross-shaped slider by a mounting assembly. This stop plate is used to abut the rear wheel of the vehicle. An adjusting screw is rotatably installed in the rear side groove. This screw is driven by a motor fixed to the rear side of the center frame. The lower end of the rear stop plate is inserted into the rear side groove and threaded with the screw. The motor drives the rear stop plate to move back and forth by rotating in both directions to adapt to the rear wheel position of vehicles with different wheelbases. The front and rear stop plates work together to firmly restrict the vehicle within the load-bearing range of the side plates.

[0007] As a preferred embodiment of the present invention, the integrated lifting mechanism specifically includes wing plates integrally formed on the left and right sides of the base frame, and side fixing columns fixed to the ground. The inner wall of the side fixing column has a vertical sliding groove, within which a vertical lead screw is rotatably mounted. This lead screw is driven to rotate by a top motor. The wing plates are threadedly engaged with the lead screw, thereby achieving smooth lifting of the base frame and the entire equipment. To further ensure lifting synchronization, both top motors on both sides are stepper motors, and their control circuits are connected in parallel in the same main control loop.

[0008] As a preferred embodiment of the present invention, anti-slip grooves are provided on the transition ramp to increase the adhesion between the tire and the ramp; rounded chamfers are machined on the lower surface edges of the end block to reduce contact wear; a handle is provided on the outer side of the vertical portion of the cross slider for easy adjustment by the operator. A spring is also provided in the front brake plate mounting assembly to provide a certain elastic buffering capacity when the front brake plate contacts the tire, avoiding rigid collision damage. Simultaneously, several protruding buckles are distributed on the opposing surfaces of the front and rear brake plates, which can be secured in the tire's grooves to improve stability and ensure the vehicle remains stable even at extreme tilt angles.

[0009] The beneficial effects of this invention are as follows: By setting up a base frame in conjunction with an overall lifting mechanism, the entire equipment can be raised and lowered smoothly, lifting the vehicle to a suitable height for maintenance work. Through the coordinated action of the front and rear hydraulic lifting machines, the side plates can be driven to rotate around their rear end shafts, raising or lowering the front end of the side plates, thereby adjusting the tilt of the vehicle parked on the side plates in the forward and backward directions. Simultaneously, through independent control of both sides of the overall lifting mechanism, the vehicle can be tilted left and right, allowing maintenance personnel to work on the chassis at the most comfortable angle, effectively avoiding cervical fatigue caused by prolonged head-tilting work. By setting a cross-slider and a front baffle on the front side that can slide forward and backward along a cross groove and be positioned through through holes and blind holes, and a rear baffle driven by an adjusting screw on the rear side, the positions of the front and rear baffles can be flexibly adjusted according to the position of the vehicle's front and rear wheels, achieving adaptive fixation for vehicles with different wheelbases. This effectively prevents the vehicle from sliding or shifting in a tilted state, ensuring the safety of maintenance work. Attached Figure Description

[0012] As a preferred technical solution of the present invention, the overall lifting mechanism includes a wing plate 2, a side fixing column 3, a vertical screw 4 and a top motor 5. The wing plate 2 is integrally formed at the middle of the left and right sides of the base frame 1. The side fixing columns 3 are fixed on the ground on both the left and right sides of the base frame 1. The inner wall of the side fixing column 3 is slotted, and the vertical screw 4 is rotatably installed in the slot. The vertical screw 4 is driven by the top motor 5 installed on the top surface of the side fixing column 3.

[0016] The working principle of this invention is as follows: During use, the positions of the front and rear baffles are adjusted according to the wheelbase of the vehicle to be repaired. For the front baffle, the cross slider is pushed along the cross groove to the appropriate position by holding the handle, and then a pin is inserted through the corresponding through hole into the blind hole of the cross slider to fix it. For the rear baffle, the motor driving the adjusting screw is started, causing the rear baffle to move along the rear side groove to the appropriate position. The vehicle drives onto the side plate from the transition ramp, positioning the front and rear wheels between the front and rear baffles respectively. The front baffle abuts against the rear side of the rear wheel, and the rear baffle abuts against the front side of the front wheel. Even after abutting, the rear baffle can still be moved by starting the motor to further improve stability. Next, the top motor is started, and the overall lifting mechanism raises the base frame and the entire equipment to a suitable height for maintenance work.

[0017] Depending on the maintenance needs, the front or rear hydraulic lift can be activated to tilt the side panel to a suitable angle, allowing maintenance personnel to perform chassis maintenance work in a comfortable position. When tilted, the components supporting the vehicle body tilt as a whole, meaning the vehicle body and its underlying load-bearing structure remain parallel. This effectively reduces wear on various components and helps extend the service life of the equipment.
