Description

Technical Field

[0001] The invention relates to the technical field of automobile chassis maintenance auxiliary devices, in particular to an automobile chassis maintenance auxiliary device. Background Art

[0002] As we all know, in automobile maintenance, when maintenance personnel need to inspect the chassis or its parts, they usually use a pad with rollers (lying board) to enter the space under the car and lie on the pad to perform maintenance operations. If the space is small, they will use a jack to slightly lift the car before entering. When maintenance personnel lie on the pad under the car, it is very inconvenient to change their posture or move due to the need for maintenance work.

[0003] Patent CN218802230U discloses an auxiliary device for automobile chassis maintenance. The pad of this solution is provided with a neck pad with sponge inside. When the maintenance personnel lie on the pad during maintenance, the neck pad plays a good supporting role for the maintenance personnel's neck, increasing the maintenance personnel's neck comfort during the maintenance process. However, the height of the neck pad cannot be adjusted. When it is necessary to look up or raise the head to perform the corresponding maintenance operations, it has almost no effect, and the head can only be raised as a pillow. Even if the height is enough, the body does not look up to match the head, and this posture is uncomfortable. In addition, the pad of this solution can only be moved by supporting the ground with hands at the bottom of the car, which is laborious, inconvenient, and may hurt the hands.

[0004] Patent CN110815159B discloses a car maintenance lying board, which drives the placing frame to rotate inward or outward while the legs apply force inward or outward, cooperates with the linkage component and the driving component to drive the roller to rotate forward or reverse, and realizes the forward and backward movement of the lying board. However, it does not take into account that the transmission structure design is relatively complex, and it is cascaded through connecting rods, screws, and gears. In actual use, it is not only inconvenient and strenuous to only clamp or open the legs on the horizontal plane to apply force and transmit it to the end to make the wheels roll. It will feel like you can't exert force, and your legs will easily get sore. Summary of the invention

[0005] The purpose of the present invention is to provide an auxiliary device for repairing an automobile chassis to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: The present invention discloses an auxiliary device for automobile chassis maintenance, comprising a lying plate, wherein four universal rollers are arranged at the bottom of the lying plate, and wherein lifting structures are symmetrically arranged on both sides of the lying plate, and the lifting structures are offset from the middle of the lying plate in the length direction; The lifting structure includes a crank and a support wheel. The two support wheels are provided with a common shaft. The crank is rotatably connected to the shaft. The crank is rotatably connected to the lying plate through a thread. The support wheel is flush with the bottom of the universal roller.

[0007] As an improvement, a fixedly connected threaded tube is provided on the top of the lying plate, and the crank thread is rotated to pass through the threaded tube and the lying plate.

[0008] As an improvement, the support wheel is arranged on the outside of the lying board and is higher than the lying board, the two ends of the shaft rod are bent in a right-angle Z shape and are rotatably connected to the support wheel, the lying board is pressed on the middle part of the shaft rod, and the crank passes under the lying board and is rotatably connected to the shaft rod.

[0009] As an improvement, peripheral flanges are provided on both sides of the support wheel.

[0010] As an improvement, the support wheel is lower than the hand-held end of the crank.

[0011] As an improvement, the shaft rod is in close contact with the outer end surface of the lying board in a vertical plane.

[0012] As an improvement, a plurality of triangular ribs are provided on the inner side of the peripheral flange.

[0013] As an improvement, the shaft rod is rotatably connected to the support wheel via a bearing.

[0014] Compared with the prior art, the advantages of the present invention are as follows: a lying board is first placed under the chassis of the automobile, and the maintenance worker lies on the lying board to perform maintenance work, and the maintenance worker lies down with his head facing the lifting structure. When it is necessary to look up or raise his head for maintenance operations, the crank handle is rotated with both hands, and it can be set to lift the lying board when the crank handle is rotated in opposite directions. Since the support wheel is biased toward the head end of the maintenance worker at the position of the lying board, the weight of the head end of the lying board is light (in practice, the maintenance worker can move his body forward and backward for better coordination). When the lying board is lifted, the foot end will continue to touch the ground, the support wheel will not move, and the head end will rise, and the maintenance worker's head will be lifted to achieve the purpose of looking up or raising his head, and then the chassis can be repaired at close range.

[0015] When the maintenance worker needs to move the lying board under the vehicle chassis, he can rotate the supporting wheels in the same direction with both hands at the same time to make the lying board move forward or backward in a straight line. When turning is required, he can rotate the supporting wheels in the opposite direction at the same time or only rotate the supporting wheels on one side.

[0016] The automobile chassis maintenance auxiliary device has a lifting structure on the lying board to make it multifunctional. The head of the lying board can be lifted by turning the crank so that the body and head of the maintenance worker can be raised as a whole. The height can be adjusted according to needs, which is convenient and comfortable for maintenance when changing postures. The lying board can be moved straight or rotated by turning the two supporting wheels. The operation is convenient and labor-saving, and it has high practical value and promotion value.

[0030] In the description of the embodiments of the present invention, if the terms "multiple" or "several" appear, they represent at least two.

[0031] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] This embodiment combines the attached Figures 1 to 8 , a vehicle chassis maintenance auxiliary device is described in detail.

[0033] This embodiment provides an auxiliary device for automobile chassis maintenance, such as Figure 3 , 4 As shown, it includes a lying board 1, and four universal rollers 2 are arranged at the bottom of the lying board 1. The universal rollers 2 are close to the ends of the lying board 1 and are fixed in position. It is characterized in that lifting structures 3 are symmetrically arranged on both sides of the lying board 1. When a person lies on the lying board 1 to repair the lower part of the automobile chassis, the lying board 1 can be lifted by operating the lifting structure 3, so that the lying board 1 is closer to the chassis for easy maintenance. The lifting structure 3 deviates from the middle of the length direction of the lying board 1; the position of the lifting structure 3 is slightly biased to one end, so that it is convenient for two-handed operation when a person lies with his head toward this end; like Figure 7 As shown, the lifting structure 3 includes a crank 31 and a support wheel 32. Figure 4As shown, the two support wheels 32 are provided with a common shaft 33. When the lying board 1 is lifted, the shaft 33 plus the support wheels 32 at both ends act as a "support frame". The crank 31 is rotatably connected to the shaft 33. The crank 31 and the shaft 33 are rotatable without threads. The crank 31 is rotatably connected to the lying board 1 through threads. Rotating the crank 31 lifts the lying board 1 through the threads. Figure 3 As shown, the support wheel 32 is flush with the bottom of the universal roller 2, and the support wheel 32 always touches the ground.

[0034] like Figure 1 As shown, a fixedly connected threaded tube 11 is provided on the top of the lying plate 1, and the crank 31 is threadedly rotated through the threaded tube 11 and the lying plate 1. The threaded tube 11 is added to make the crank 31 more stable when rotating.

[0035] like Figure 3 As shown, the support wheel 32 is arranged on the outside of the lying board 1 and is higher than the lying board 1, which is convenient for turning the support wheel 32 by hand. The two ends of the shaft rod 33 are bent in a right-angle Z shape and are rotatably connected to the support wheel 32. When the support wheel 32 rotates, it does not affect the crank 31. The lying board 1 is pressed on the middle part of the shaft rod 33. When the lying board 1 is at the lowest, it is directly pressed on the shaft rod 33. The crank 31 passes through the lying board 1 and is rotatably connected to the shaft rod 33. There are protrusions around the lower end of the crank 31 to limit the shaft rod 33. The lower end of the crank 31 is always below the lying board 1.

[0036] like Figure 4 As shown, the supporting wheel 32 is provided with peripheral flanges 4 on both sides. It is more convenient to rotate the supporting wheel 32 with force by grasping the peripheral flanges 4 by hand.

[0037] like Figure 4 As shown, the support wheel 32 is lower than the hand-held end of the crank 31. Rotating the crank 31 will not be blocked by the support wheel 32, and the transverse rod part of the crank 31 can be extended to make the rotation more labor-saving.

[0038] like Figure 4 , 6 As shown, the shaft rod 33 is in a vertical plane against the outer end surface of the lying plate 1, thereby reducing the overall width and reducing the lateral pressure of the shaft rod 33 when the supporting wheel 32 is operated to rotate the lying plate 1.

[0039] like Figure 1 , 5 As shown, a plurality of triangular ribs 41 are provided inside the peripheral flange 4. The triangular ribs 41 are added so that the hand does not slip when grasping the peripheral flange 4 and rotating, making it easier to put on the neck.

[0040] like Figure 5 As shown, the shaft rod 33 is rotatably connected to the support wheel 32 via a bearing.

[0041] In specific implementation, the lying board 1 is first placed under the chassis of the automobile, and the maintenance worker lies on the lying board 1 to perform maintenance work, and the maintenance worker lies down with his head facing the lifting structure 3. When it is necessary to look up or raise his head for maintenance operations, the maintenance worker rotates the crank 31 with both hands, and it can be set to lift the lying board 1 when the crank 31 is rotated in opposite directions. Since the support wheel 32 is located at the lying board 1 and is biased toward the maintenance worker's head end, the weight of the head end on the lying board 1 is light (in practice, the maintenance worker can move his body forward and backward to better cooperate). When the lying board 1 is lifted, the foot end will continue to touch the ground, the support wheel 32 will not move, and the head end will rise, and the maintenance worker's head will be lifted to achieve the purpose of looking up or raising his head, and then the chassis can be repaired at close range.

[0042] When the maintenance worker needs to move the lying board 1 under the vehicle chassis, he can rotate the supporting wheels 32 in the same direction with both hands to make the lying board 1 move forward or backward in a straight line. When turning, he can rotate the supporting wheels 32 in the opposite direction at the same time or only rotate the supporting wheels 32 on one side.

[0043] like Figure 8 As shown, the middle section of the crank 31 can be threadedly rotated to extend and retract.

[0044] In the specific implementation, the outer end of the crank is first slightly turned away from the support wheel 32, and then the outer end of the crank 31 is rotated in the vertical plane to extend the middle section, so that the operation of rotating the crank 31 in the horizontal plane to lift the lying board 1 is more labor-saving.

[0045] The present invention and its embodiments are described above, and such description is not restrictive, and the actual protection scope is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
