Description

Technical Field

[0001] The invention relates to the technical field of automobile maintenance, and in particular to a vehicle body auxiliary tilting device for maintenance. Background Art

[0002] With the continuous advancement of automobile technology, automobile structures have become more and more complex, and maintenance work has become more professional and delicate accordingly. Traditional maintenance methods often require technicians to work in undesirable postures, such as lying on the ground or bending over to perform chassis inspections, which is not only inefficient, but also long-term incorrect postures may lead to occupational health problems. In addition, some maintenance work requires the vehicle to be at a specific tilt angle to better access the maintenance point. Although traditional jacks and lifts can lift the vehicle, it is difficult to adjust the angle and is not precise enough. In order to solve these problems, the body auxiliary tilt device came into being.

[0003] For example, Chinese patent publication number CN214399660U discloses a vehicle tilting device for vehicle maintenance.

[0004] It relates to the technical field of automobile maintenance, including a supporting device, a telescopic device, a vehicle body device, a rotating device and an auxiliary device. The supporting device includes a bottom plate and a supporting column. The telescopic device includes an L-shaped plate and a supporting plate. The upper ends of several supporting columns are welded to the lower surface of the supporting plate. The vehicle body device includes an anti-skid pad. The lower surfaces of several anti-skid pads are respectively welded to the upper surfaces of several L-shaped plates. The rotating device includes a rotating bracket. The lower ends of several rotating brackets are welded to the upper surface of the bottom plate. The auxiliary device includes an auxiliary bracket. The lower ends of several auxiliary brackets are welded to the upper surface of the bottom plate. A vehicle tilting device for automobile maintenance, the extension and retraction of the telescopic cylinder can drive the vehicle to tilt, the rotating device can drive the rotating belt to rotate, so that the maintenance worker lying on the rotating belt can reach any position under the vehicle, and the anti-skid pad can prevent the vehicle body from moving.

[0005] However, the above-mentioned vehicle tilting device for vehicle maintenance still has some shortcomings in actual use:

[0006] 1. The above device supports the car to be repaired by a supporting device, and then uses a telescopic cylinder to drive the car to tilt, so as to facilitate workers to repair the car. However, during the repair process, only the anti-slip pad is used to prevent the car body from moving, and the safety factor is low. When the car body tilts at a large angle, it will roll over, causing further damage to the vehicle and threatening the personal safety of the maintenance workers.

[0007] 2. The above device uses a conveyor belt to move the maintenance personnel, who are lying on the rotating belt, to the bottom of the vehicle to perform maintenance on the bottom of the vehicle. However, since this method will reduce the operating space of the maintenance personnel, their range of movement and posture may be limited, which may affect the precision and efficiency of the maintenance work.

[0008] Therefore, under the viewpoint of the above statement, there is still room for improvement in the existing automobile tilting device for automobile maintenance. Summary of the invention

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-Figure 8 Embodiments of the present invention are described in detail.

[0032] The embodiment of the present application discloses an auxiliary vehicle body tilting device for maintenance, which explains that the auxiliary vehicle body tilting device for maintenance is mainly used in the process of automobile maintenance. In terms of technical effect, it can avoid the problem of merely supporting the automobile during the maintenance process without further fixing measures, which causes further damage to the vehicle and threatens the personal safety of the maintenance workers; further, it can also solve the problem that people need to lie under the automobile to repair the automobile, resulting in a small operating space, limited range of activities, and affected maintenance quality.

[0033] Embodiment 1:

[0034] Reference Figure 1 , Figure 2 and Figure 4 As shown, it includes a support frame 1, and a triangular plate 10 is installed on one side of the support frame 1 in the length direction. When the wheels of the car are intact, the car is driven onto the support frame 1 through the triangular plate 10 for subsequent maintenance. A support plate 11 for placing the car is installed above the support frame 1, and driving blocks are slidably installed at the opposite ends of the support plate 11. When the car moves onto the support frame 1, the support plate 11 will be located under the bottom plate of the car and between the wheels on both sides during the movement, which will not affect the movement of the car. A support mechanism 20 for supporting the car is installed on the support plate 11. Rotating the support plate 11 on one side will make the chassis of the car leak out, which is convenient for maintenance personnel to inspect and repair the bottom of the car. During the rotation process, the support mechanism 20 is used to limit the car to prevent the car from falling under the action of gravity.

[0035] The support mechanism 20 includes a slider 21, a slide groove 22 is provided on the driving block, the slider 21 is slidably arranged inside the slide groove 22, a butt plate 23 is rotatably arranged on the slider 21, a storage groove is provided at the bottom of one side of the support plate 11, and the butt plate 23 is arranged inside the storage groove. When the car moves to the support frame 1, the driving block is pushed to drive the butt plate 23 on the driving block to extend out of the bottom of the car to adapt to the external width of the car, and then the butt plate 23 on the slider 21 is rotated and flipped until it is parallel to the side of the car. During the tilting process of the car, the tilted car is supported by the butt plate 23 to prevent the car on the support plate 11 from sliding off. A driving member 24 is installed on the support frame 1 to drive the butt plate 23 to move and rotate, and the driving member 24 drives the butt plate 23 to slide out of the bottom of the car and then rotate.

[0036] Reference Figure 4 , Figure 5 and Figure 6 As shown, it is a schematic diagram of the structure for driving the slider 21 to move; specifically, the driving member 24 includes a mounting plate 240 arranged on the support frame 1, a two-way cylinder 241 is arranged on the mounting plate 240, a telescopic spring rod 242 is installed on the output shaft of the two-way cylinder 241, and a push plate 243 is slidably arranged at one end of the slide groove 22 close to the two-way cylinder 241, and the push plate 243 is connected to the telescopic spring rod 242.

[0037] When the two-way cylinder 241 drives the telescopic spring rod 242 to move in the direction of the slider 21, the push plate 243 on the telescopic spring rod 242 is driven to push the slider 21 to move inside the slide groove 22. A tension spring (not shown in the figure) is installed between the push plate 243 and the slider 21. When the push plate 243 returns to the initial position under the drive of the two-way cylinder 241, the slider 21 is driven to return to the initial position through the tension spring, so that the car can be driven out after the maintenance is completed, and preparations can be made for the maintenance of the next car.

[0038] Reference Figure 4 , Figure 5 and Figure 6 As shown, that is, a schematic diagram of the structure for driving the support plate 23 to rotate; specifically, the driving member 24 also includes a driving shaft 244, which is installed on one side of the support plate 11 along the length direction of the support plate 11, and a driving rack 245 is provided on the fixed section of the telescopic spring rod 242, and a driving gear 246 meshing with the driving rack 245 is provided at one end of the driving shaft 244 away from the support plate 11. When the slider 21 slides to the end of the slide groove 22, the telescopic section of the telescopic spring rod 242 is limited by the slider 21 and retracted. At this time, the fixed end of the telescopic spring rod 242 will continue to move under the drive of the two-way cylinder 241. The driving rack 245 on the telescopic spring rod 242 drives the vehicle to rotate. A first synchronous wheel 247 is also installed on the driving shaft 244. A rotating shaft connected to the butt plate 23 is rotatably provided on the slider 21. A second synchronous wheel 248 is installed on the rotating shaft. A synchronous belt 249 is commonly sleeved on the first synchronous wheel 247 and the second synchronous wheel 248. The driving gear 246 rotates to drive the first synchronous wheel 247 to rotate and then drives the butt plate 23 to rotate under the cooperation of the second synchronous wheel 248 and the synchronous belt 249. At this time, the butt plate 23 can be driven to rotate until the butt plate 23 flips 270 degrees and is parallel to the side of the car.

[0039] It should be noted that the elastic force of the telescopic spring rod 242 is greater than the thrust of the abutment plate 23 on the slider 21, so that when the slider 21 moves in the slide slot 22, the telescopic spring rod 242 will not shrink until the slider 21 moves to the end of the slide slot 22, at which time the telescopic spring rod 242 shrinks and the bidirectional cylinder 241 continues to work. The fixed end of the telescopic spring rod 242 continues to approach the slider 21, causing the driving gear 246 to rotate.

[0040] Reference Figure 4 , Figure 5 and Figure 6 As shown, it is a schematic diagram of the structure for supporting the synchronous belt 249; specifically, a support groove 30 is opened on the support plate 11, and a support block is installed inside the support groove 30 through spring sliding, and a support pulley 31 is rotatably arranged on the support block, and the support pulley 31 always conflicts with the inner wall of the synchronous belt 249.

[0041] When the slider 21 drives the second synchronous wheel 248 above it to move, the synchronous belt 249 will be gradually straightened, driving the support pulley 31 to slide downward with the movement of the synchronous belt 249, and the spring will give the support pulley 31 an upward force, so that the support pulley 31 can be driven to always contact the inner wall of the synchronous belt 249.

[0042] Since the length of the synchronous belt 249 is fixed, before the slider 21 slides, the synchronous belt 249 mounted on the first synchronous wheel 247 and the second synchronous wheel 248 is relatively loose and cannot be completely tightly attached to the first synchronous wheel 247 and the second synchronous wheel 248, which will cause the synchronous belt 249 to fall off, which will affect the subsequent rotation of the anti-plate 23 and fail to drive the anti-plate 23 to rotate.

[0043] Reference Figure 4 , Figure 5 and Figure 7 As shown, it is a schematic diagram of the structure for driving the support plate 11 to rotate; specifically, the support frame 1 is also provided with a pulling member 4 for driving one of the support plates 11 to rotate with the other support plate 11 as the center, the pulling member 4 includes a mounting block 40, the mounting block 40 is arranged at the bottom of both ends of the support plate 11, and a support shaft 41 is arranged between the mounting blocks 40 for common rotation, one of the support shafts 41 is rotatably arranged on the support frame 1, and an arc plate 42 is installed on the support frame 1 on the side away from the triangular plate 10. It should be noted that the radius of the arc plate 42 is equal to the length between the two support shafts 41, the center of the arc plate 42 coincides with the axis of the support shaft 41 rotatably arranged on the support frame 1, an arc groove 43 is opened on the arc plate 42, and one end of the other support shaft 41 slides inside the arc groove 43, and a motor 44 is also installed on the support frame 1, and a cable 45 is arranged inside the arc groove 43 together with the output end of the motor 44 and the end of the support shaft 41 located in the arc groove 43.

[0044] A cable 45 is wound around the output shaft of the motor 44. When the motor 44 rotates clockwise, the cable 45 will be gradually wound around the output shaft of the motor 44. Then, under the pulling force of the cable 45, the other output shaft will drive the output shaft with one end located in the arc groove 43 to slide inside the arc groove 43. Then, a support plate 11 connected to the support shaft 41 sliding in the arc groove 43 will rotate along the other support plate 11. At this time, the car on the support plate 11 will tilt along with the rotation of the support plate 11. The tilt angle is determined by the number of rotations of the output shaft of the motor 44 and is manually adjusted as needed.

[0045] Reference Figure 7 As shown, it is a schematic diagram of the structure for further improving the stability of automobile placement; specifically, the support frame 1 is also equipped with a support member 5 for supporting the support shaft 41 sliding in the arc groove 43 to improve the stability of the support plate 11 supporting the automobile, and the support member 5 includes a first screw rod 50, and the two first screw rods 50 are symmetrically rotated and installed on the support frame 1 along the width direction of the support frame 1. A support seat 51 is threadedly arranged on the first screw rod 50, and a support rod 52 is hingedly installed on the support seat 51, and the end of the support rod 52 away from the support seat 51 is hingedly arranged with the support shaft 41 sliding in the arc groove 43.

[0046] The first screw 50 works synchronously with the motor 44 . When the support plate 11 rotates, the support seat 51 moves synchronously along the length direction of the first screw 50 . Then, the support rod 52 on the support seat 51 rotates on the support seat 51 to support the support shaft 41 .

[0047] The purpose of setting the support member 5 is that since the arc groove 43 is only set on one side of the support frame 1, when the car on the support frame 1 is driven to rotate, only one side of the support frame 1 is subjected to force, and it may deflect during the rotation process, causing the car to slide, thereby causing secondary damage to the departure and threatening the safety of maintenance personnel. In addition, long-term one-sided force will also lead to a reduction in the service life of the support plate 11, reducing the practicality of the present invention. Therefore, the support member 5 is set to support the two ends of the support rod 52 under the support plate 11, thereby improving the stability of the support plate 11 supporting the car, and being able to provide double support to the support plate 11, thereby improving the safety of the car placement.

[0048] Reference Figure 7 and Figure 8 As shown, that is, a schematic diagram of the structural mechanism that prevents the support rod 52 from rotating; specifically, the support frame 1 is also provided with a clamping member 6 that prevents the support rod 52 from rotating under the action of gravity, and the clamping member 6 includes a connecting shaft 60. The two support rods 52 are hingedly set on the support seat 51 through the connecting shaft 60, and clamping gears 61 are installed at both ends of the connecting shaft 60. A clamping rack 62 is arranged on the support frame 1 along the width direction of the support frame 1, and the clamping rack 62 is meshed with the clamping gear 61.

[0049] When the connecting shaft 60 moves with the support seat 51, the engaging gear 61 on the connecting shaft 60 will mesh with the engaging rack 62 and then rotate synchronously. However, if the first screw rod 50 does not rotate, the support seat 51 cannot move, and the engaging gear 61 connected to the connecting shaft 60 will not rotate, and the support rod 52 will not rotate either.

[0050] The reason for this arrangement is that if the motor 44 fails, the cable 45 releases the support plate 11. Since the support plate 11 is also supported by the support rod 52 at the same time, the support plate 11 will not fall suddenly, thereby preventing the life safety of the repair personnel from being threatened during the repair process and ensuring that the vehicle will not suffer secondary damage.

[0051] Embodiment 2:

[0052] On the basis of the first embodiment, in order to further enhance the fixation of the automobile, a fixing member 7 is also proposed, which is helpful in preventing the rotation angle from being too large during the process of driving the automobile to rotate, causing the automobile to tilt in the opposite direction of rotation, resulting in damage to the automobile and endangering the personal safety of maintenance personnel.

[0053] Reference Figure 2 and Figure 3 As shown, it is a schematic diagram of the structure for further fixing the automobile; specifically, the fixing member 7 includes a first fixing ring 70 and a second fixing ring 71, two groups of one fixing ring and a second fixing ring 71 are installed on both sides of the support frame 1, the first fixing ring 70 is rotatably installed on the support frame 1 through a volute spring, and the second fixing ring 71 is rotatably set on the support frame 1, the first fixing ring 70 and the second fixing ring 71 are commonly connected with a fixing rope 72, and the second fixing ring 71 is connected to the first screw 50 through a belt drive.

[0054] When the car is placed on the support frame 1, the fixing rope 72 is pulled, and the first fixing ring 70 rotates at this time. The spiral spring inside the first fixing ring 70 is forced to shrink, and the fixing rope 72 is clamped on the inner side of the car wheel. The fixing rope 72 is loosened, and the spiral spring stretches to tighten the fixing rope 72. Then, when the support plate 11 rotates, the second fixing ring 71 rotates synchronously with the first screw rod 50 to release the excess of the fixing rope 72. The length of the rope is adjusted according to the rotation angle of the support plate 11 to ensure that the fixing rope 72 is always set on the inner side of the car. The reason for this arrangement is to prevent the car from turning too much and causing the car to flip over.

[0055] During operation: First, the car is driven onto the support frame 1 through the triangular plate 10, and the fixing rope 72 is pulled to clamp the fixing rope 72 on the inner side of the wheel of the car.

[0056] Step 2: The bidirectional cylinder 241 starts to work, driving the telescopic spring rod 242 to move toward the slider 21, and the push plate 243 on the slider 21 pushes the slider 21, so that the abutment plate 23 on the driving block extends out of the bottom of the car to adapt to the external width of the car.

[0057] Step 3: Then the push plate 243 continues to move, the telescopic spring rod 242 contracts, the driving rack 245 on the telescopic spring rod 242 drives the driving gear 246 to rotate, and then drives the first synchronous wheel 247 and the second synchronous wheel 248 to rotate synchronously, and rotates the abutment plate 23 set on the slider 21, which can drive the abutment plate 23 to rotate until the abutment plate 23 flips 270 degrees and is parallel to the side of the car.

[0058] Step 4: When the motor 44 rotates clockwise, the cable 45 is gradually wound around the output shaft of the motor 44. Under the pulling force of the cable 45, the other output shaft will rotate along the other support plate 11 connected to the support shaft 41 sliding in the arc groove 43. At this time, the car on the support plate 11 will tilt with the rotation of the support plate 11, and the maintenance personnel will inspect the car.

[0059] Step 5: After the inspection is completed, the motor 44 rotates counterclockwise to drive the two support plates 11 back to the initial position, and the telescopic end of the two-way cylinder 241 contracts to release the clamping of the car, completing the inspection.

[0060] It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

[0061] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
