TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile calibration equipment, in particular to a beam mechanism, an automobile calibration equipment and an automobile calibration system. BACKGROUND

[0002] In the field of automobile calibration equipment, due to the involvement of moving parts and the limitation of structural space, cable arrangement has great challenges. In particular, the transmission structure position of part of the devices is special, which leads to great difficulty in wiring at the transmission structure, great loss of wire during the movement of the parts, and frequent occurrence of problems such as wire breakage, short circuit and wear, thus causing extremely bad customer experience and seriously affecting normal operation efficiency. CONTENT OF THE UTILITY MODEL

[0003] Embodiments of the present application aim to provide a beam mechanism, an automobile calibration equipment and an automobile calibration system to solve the technical problem that the transmission structure of the automobile calibration equipment in the prior art is difficult to wire.

[0004] Embodiments of the present application solve the technical problem by adopting the following technical solutions:

[0005] A beam mechanism is provided, characterized in that it comprises:

[0006] A beam assembly comprising a first beam and a second beam, the first beam being hinged to the second beam, the first beam being provided with a movable first sliding plate, and the second beam being provided with a movable second sliding plate;

[0007] A rotating assembly comprising a first rotating mechanism and a second rotating mechanism, the first rotating mechanism being drivingly connected to the first beam, the first rotating mechanism being configured with a first rotation center, the first rotating mechanism being configured to drive the first beam to rotate around the first rotation center, the second rotating mechanism being drivingly connected to the second beam, the second rotating mechanism being configured with a second rotation center, and the second rotating mechanism being configured to drive the second beam to rotate around the second rotation center;

[0008] A drag chain assembly comprising a first drag chain, a second drag chain and a third drag chain, the first drag chain being arranged in the first beam, the second drag chain being arranged in the second beam, the active end of the first drag chain being connected to the first sliding plate, the active end of the second drag chain being connected to the second sliding plate, and the third drag chain being arranged in the first beam and the second beam, one end of the third drag chain being connected to the first beam, and the other end of the third drag chain being connected to the second beam.

[0009] Through the above structure, the movable end of the first drag chain follows the movement of the first sliding plate, thereby driving the cable connected to the first sliding plate to move synchronously, so that the cable can support the first sliding plate to freely move to any position on the first cross beam. The movable end of the second drag chain follows the movement of the second sliding plate, thereby driving the cable connected to the second sliding plate to move synchronously, so that the cable can support the second sliding plate to freely move to any position on the second cross beam. The third drag chain is connected to the first cross beam and the second cross beam, so that when the first cross beam and / or the second cross beam rotates, the cable can support the rotating action of the first cross beam and / or the second cross beam.

[0010] In some embodiments, the first cross beam is provided with a first cavity, the first drag chain is located in the first cavity, and the height of the first cavity is greater than or equal to the turning radius of the first drag chain.

[0011] Through the above structure, the height of the first cavity is greater than or equal to the turning radius of the first drag chain, so that the size space inside the first cross beam can be fully utilized, so that the first cavity can not only satisfy the turning of the first drag chain to realize the movement of following the sliding plate, but also limit the movement of the first drag chain through the height of the first cavity, avoiding the phenomena such as cable twisting, winding and cable loss, thereby effectively solving the problems such as line breakage and short circuit caused by the free movement of the sliding plate.

[0012] In some embodiments, the fixed end of the first drag chain is connected to one end of the first cavity close to the second cross beam, and the first drag chain is configured to bend or flatten following the movement of the first sliding plate.

[0013] Through the above structure, the fixed end of the first drag chain is fixed inside the first cavity, and the movable end moves inside the first cavity following the movement of the sliding plate. When the sliding plate moves to one end of the first cross beam away from the second cross beam, the first drag chain has a flattening movement trend to increase the length of the cable in the horizontal direction by flattening; when the sliding plate moves to one end of the first cross beam close to the second cross beam, the first drag chain has a bending movement trend to reduce the length of the cable in the horizontal direction by winding.

[0014] In some embodiments, the second cross beam is provided with a second cavity, the second drag chain is located in the second cavity, and the height of the second cavity is greater than or equal to the turning radius of the second drag chain.

[0015] Through the above structure, the height of the second cavity is greater than or equal to the turning radius of the second drag chain, the size space inside the second cross beam can be fully utilized, so that the second cavity can not only meet the turning of the second drag chain to realize the following sliding plate movement, but also limit the movement of the second drag chain through the height of the second cavity, avoid the phenomenon of cable twisting, winding and cable loss, etc., thereby effectively solving the problems of line breakage, short circuit and other problems caused by the free movement of the sliding plate.

[0016] In some embodiments, the fixed end of the second drag chain is connected to the second cavity relatively close to the two ends of the second cross beam, and the second drag chain is configured to bend or flatten the movable end following the movement of the second sliding plate.

[0017] Through the above structure, the fixed end of the second drag chain is fixed inside the second cavity, and the movable end moves inside the second cavity following the movement of the sliding plate. When the sliding plate moves to the end of the second cross beam away from the first cross beam, the second drag chain has a flattening movement trend to increase the length of the cable in the horizontal direction by flattening; when the sliding plate moves to the end of the second cross beam close to the first cross beam, the second drag chain has a bending movement trend to reduce the length of the cable in the horizontal direction by winding.

[0018] In some embodiments, a third cavity is provided in communication inside the first cross beam and the second cross beam, the third drag chain is located in the third cavity, and the height of the third cavity is greater than or equal to the turning radius of the third drag chain.

[0019] Through the above structure, the third cavity is in communication inside the first cross beam and the second cross beam, so that the third drag chain can be connected to the first cross beam and the second cross beam at the same time. When the first cross beam and / or the second cross beam rotates, since the height of the third cavity is greater than or equal to the turning radius of the third drag chain, the third drag chain has enough space to bend and flatten synchronously following the rotation of the first cross beam and / or the second cross beam, so as to ensure that the cable provided in the third drag chain can still be connected to the first cross beam and the second cross beam.

[0020] In some embodiments, the fixed end of the third drag chain is provided at one end of the third cavity located in the first cross beam, the movable end of the third drag chain is provided at one end of the third cavity located in the second cross beam, and the third drag chain is configured to bend or flatten the movable end following the rotation of the first cross beam and / or the second cross beam.

[0021] Through the above structure, the fixed end and the movable end of the third drag chain are arranged inside the first cross beam and the second cross beam respectively, when the first cross beam and the second cross beam are rotated to the vertical upward direction, the movable end part of the third drag chain changes from the curved state to the flat state, so as to increase the expansion length of the third drag chain, and fill the horizontal distance between the end of the first cross beam and the end of the second cross beam. When the first cross beam and the second cross beam are rotated to the horizontal direction, the movable end part of the third drag chain changes from the flat state to the curved state, so that the excess length part of the third drag chain is curled and stored at this time.

[0022] In some embodiments, a reinforcing belt is arranged in the third drag chain, and the reinforcing belt is made of a ductile material.

[0023] Through the above structure, when the third drag chain is bent or expanded following the rotation of the first cross beam and / or the second cross beam, the deformation range of the third drag chain is large, and by arranging the reinforcing belt with ductility in the third drag chain, the ductility of the third drag chain can be improved, so as to improve the deformation recovery ability of the third drag chain, and meet the contraction requirement following the rotation of the first cross beam and / or the second cross beam.

[0024] Another embodiment of the present application also provides an automobile calibration device, which comprises the cross beam mechanism in any of the above embodiments.

[0025] Still another embodiment of the present application also provides an automobile calibration system, which comprises the automobile calibration device in the above embodiment.

[0026] Compared with the prior art, the movable end of the first drag chain moves following the first sliding plate, thereby driving the cable connected with the first sliding plate to move synchronously, so that the cable can support the first sliding plate to move freely to any position on the first cross beam. The movable end of the second drag chain moves following the second sliding plate, thereby driving the cable connected with the second sliding plate to move synchronously, so that the cable can support the second sliding plate to move freely to any position on the second cross beam. The third drag chain is connected with the first cross beam and the second cross beam, so that when the first cross beam and / or the second cross beam rotates, the cable can support the rotation action of the first cross beam and / or the second cross beam.

[0038] The beam mechanism, the automobile calibration device and the automobile calibration system provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 1 is a perspective view of a beam mechanism according to an embodiment of the present application, Figure 2 FIG. 2 is a sectional view of the beam mechanism according to an embodiment of the present application. The beam mechanism 100 according to an embodiment of the present application comprises a beam assembly 10, a rotating assembly 20 and a drag chain assembly 30. The beam assembly 10 comprises a first beam 11 and a second beam 12, the first beam 11 is hinged to the second beam 12, the first beam 11 is provided with a movable first sliding plate 111, and the second beam 12 is provided with a movable second sliding plate 121. The rotating assembly 20 comprises a first rotating mechanism 21 and a second rotating mechanism 22, the first rotating mechanism 21 is drivingly connected to the first beam 11, the first rotating mechanism 21 is provided with a first rotating center 211, and the first rotating mechanism 21 is configured to drive the first beam 11 to rotate around the first rotating center 211. The second rotating mechanism 22 is drivingly connected to the second beam 12, the second rotating mechanism 22 is provided with a second rotating center 221, and the second rotating mechanism 22 is configured to drive the second beam 12 to rotate around the second rotating center 221. The drag chain assembly 30 comprises a first drag chain 31, a second drag chain 32 and a third drag chain 33. The first drag chain 31 is arranged in the first beam 11, the second drag chain 32 is arranged in the second beam 12, the movable end of the first drag chain 31 is connected to the first sliding plate 111, the movable end of the second drag chain 32 is connected to the second sliding plate 121, and the third drag chain 33 is arranged in the first beam 11 and the second beam 12, one end of the third drag chain 33 is connected to the first beam 11, and the other end of the third drag chain 33 is connected to the second beam 12.

[0040] Through the above structure, the movable end of the first drag chain 31 moves along with the first sliding plate 111, thereby driving the cable connected to the first sliding plate 111 to move synchronously, so that the cable can support the first sliding plate 111 to move freely to any position in the first beam 11. The movable end of the second drag chain 32 moves along with the second sliding plate 121, thereby driving the cable connected to the second sliding plate 121 to move synchronously, so that the cable can support the second sliding plate 121 to move freely to any position in the second beam 12. The third drag chain 33 connects the first beam 11 and the second beam 12, so that when the first beam 11 and / or the second beam 12 rotates, the cable can support the rotating action of the first beam 11 and / or the second beam 12.

[0041] Specifically, in the embodiments of the present application, the first cross beam 11 and the second cross beam 12 are both hollow, and have a plurality of cavities inside for accommodating cables and other electronic devices. The first cross beam 11 is provided with a first sliding plate 111, and the first sliding plate 111 is provided with an AVM laser instrument for assisting calibration of a vehicle. The first cross beam 11 is provided with a moving guide rail, and the first sliding plate 111 is clamped to the moving guide rail, so that the first sliding plate 111 can move along the axial direction of the moving guide rail, i.e. the horizontal direction, on the first cross beam 11. When the first sliding plate 111 moves, the AVM laser instrument also moves to align the edge of the vehicle for calibration. With different types of vehicles, when the width of the vehicle changes, the first sliding plate 111 can be adjusted to ensure that the AVM laser instrument aligns with the edge of the vehicle, thereby improving the calibration accuracy of the vehicle and achieving the calibration purpose. Obviously, when the AVM laser instrument moves, the cable connected to the AVM laser instrument should also move, so the first drag chain 31 provided with the cable is also arranged to move with the first sliding plate 111, so as to ensure that the cable can support the AVM laser instrument to work normally at any position on the first cross beam 11. The working principle of the second sliding plate 121 and the second drag chain 32 is the same as that of the first sliding plate 111 and the first drag chain 31, and thus will not be described again.

[0042] The first rotating mechanism 21 includes a motor and a connecting plate (not labeled in the figure) in transmission connection with the motor. The connecting plate is fixedly connected to one end of the first cross beam 11 close to the second cross beam 12. When the motor drives the connecting plate to rotate clockwise in the vertical upward direction, the connecting plate can drive the first cross beam 11 to rotate together, thereby realizing the conversion of the horizontally placed first cross beam 11 to the vertically placed first cross beam 11, so as to reduce the volume occupied by the vehicle calibration device for easy storage. The second cross beam 12 is symmetrically arranged with the first cross beam 11. Similarly, the second cross beam 12 is provided with a second sliding plate 121 for installing an AVM laser instrument, and the second cross beam 12 is connected to a second rotating center 221 and can be driven by the motor of the second rotating center 221 to rotate counterclockwise to the vertical upward position. Other details will not be described again.

[0043] In some embodiments, the first cross beam 11 is provided with a first cavity 112, and the first drag chain 31 is located in the first cavity 112. The height of the first cavity 112 is greater than or equal to the turning radius of the first drag chain 31.

[0044] Through the above structure, the height of the first cavity 112 is greater than or equal to the turning radius of the first drag chain 31, the size space inside the first cross beam 11 can be fully utilized, so that the first cavity 112 can not only meet the turning of the first drag chain 31 to realize the following sliding plate movement, but also limit the movement of the first drag chain 31 through the height of the first cavity 112, avoid the phenomenon of cable twisting, winding and cable loss, etc., thereby effectively solving the problems of line breakage, short circuit and other problems caused by the free movement of the sliding plate.

[0045] Specifically, in the embodiment of the present application, the height of the first cavity 112 is slightly greater than the turning radius of the first drag chain 31, so that the first cavity 112 limits the first drag chain 31, that is, the active end of the first drag chain 31 can only realize the folding length by bending in the first cavity 112. For example, when the active end of the first drag chain 31 is completely bent, the bending part is in the shape of a semicircle. At this time, the length of the first drag chain 31 actually occupied by the bending part is πR, where R is the radius of the bending part, and the length of the bending part in the horizontal direction is R, which is equivalent to shortening the length of the first drag chain 31(πR-R) in the horizontal direction. If the active end of the first drag chain 31 continues to move towards the proximal end 113 of the first cross beam 11 (i.e. close to one end of the second cross beam 12) after being completely bent, the bending radius of the first drag chain 31 will not further increase, but the radius of the bending part will remain the same, constantly pushing the bending part to follow the first active end to move towards the proximal end 113 of the first cross beam 11.

[0046] In some embodiments, the fixed end 311 of the first drag chain 31 is connected to the end of the first cavity 112 relatively close to the second cross beam 12, and the first drag chain 31 is configured to bend or flatten the active end 312 following the movement of the first sliding plate 111.

[0047] Through the above structure, the fixed end 311 of the first drag chain 31 is fixed inside the first cavity 112, and the active end 312 moves inside the first cavity 112 following the movement of the first sliding plate 111. When the first sliding plate 111 moves to the distal end 114 of the first cross beam 11 (i.e. away from one end of the second cross beam 12), the first drag chain 31 has a tendency to flatten to increase the length of the cable in the horizontal direction by flattening; when the first sliding plate 111 moves to the proximal end 113 of the first cross beam 11, the first drag chain 31 has a tendency to bend to reduce the length of the cable in the horizontal direction by winding.

[0048] Specifically, in the embodiments of the present application, when the first sliding plate 111 is at the distal end 114 of the first cross beam 11, the first drag chain 31 is fully unfolded to increase the length to support the AVM laser instrument on the first sliding plate 111. As the first sliding plate 111 moves towards the proximal end 113, the first drag chain 31 gradually bends until it forms a semicircle, at which time the diameter of the semicircle is the turning radius. At this time, the moving direction of the active end 312 of the first drag chain 31 is consistent with the moving direction of the first sliding plate 111 towards the proximal end 113 of the first cross beam 11, and opposite to the unfolding direction of the fixed end 311 of the first drag chain 31. Thus, in addition to the length of the first drag chain 31 that is folded at the bending portion, the distance from the active end 312 of the first drag chain 31 to the bending portion is also equivalent to being folded, thereby further reducing the length of the first drag chain 31 in the horizontal direction to cooperate with the AVM laser instrument on the first sliding plate 111 to work at the proximal end of the first cross beam 11. For example, the horizontal distance from the active end 312 of the first drag chain 31 to the bending portion is L, and the shortened length of the first drag chain 31 in the horizontal direction is L + (πR - R).

[0049] In some embodiments, the second cross beam 12 is provided with a second cavity 122, and the second drag chain 32 is located in the second cavity 122. The height of the second cavity 122 is greater than or equal to the turning radius of the second drag chain 32.

[0050] Through the above structure, the height of the second cavity 122 is greater than or equal to the turning radius of the second drag chain 32, so that the size space inside the second cross beam 12 can be fully utilized. The second cavity 122 can not only satisfy the turning of the second drag chain 32 to realize the following movement of the sliding plate, but also limit the movement of the second drag chain 32 through the height of the second cavity 122, so as to avoid the phenomena such as cable twisting, winding and cable loss, thereby effectively solving the problems such as easy disconnection and short circuit of the line when the sliding plate freely moves.

[0051] Specifically, in the embodiments of the present application, the second cavity 122 has a similar overall structure to the first cavity 112, and the limiting effect of the second cavity 122 on the second drag chain 32 has the same principle as the limiting effect of the first cavity 112 on the first drag chain 31. Those skilled in the art can refer to the above embodiments of the first cavity 112 to implement the structural technical solutions of the second cavity 122, which will not be described here.

[0052] In some embodiments, the fixed end 321 of the second drag chain 32 is connected to the proximal end 123 of the second cross beam 12 (i.e. the end close to the first cross beam 11), and the second drag chain 32 is configured to bend or flatten with the movement of the active end 322 following the movement of the second sliding plate 121.

[0053] Through the above structure, the fixed end 321 of the second drag chain 32 is fixed inside the second cavity 122, and the movable end 322 moves inside the second cavity 122 following the movement of the second sliding plate 121. When the second sliding plate 121 moves to the far end 124 of the second cross beam 12 (i.e., the end away from the first cross beam 11), the second drag chain 32 has a tendency to flatten to increase the length of the cable in the horizontal direction by flattening; when the second sliding plate 121 moves to the near end 123 of the second cross beam 12, the second drag chain 32 has a tendency to bend to reduce the length of the cable in the horizontal direction by curling.

[0054] Specifically, in the embodiment of the present application, the second cavity 122 has a similar overall structure to the first cavity 112, and the limiting effect of the second cavity 122 on the second drag chain 32 has the same principle as the limiting effect of the first cavity 112 on the first drag chain 31. Those skilled in the art can refer to the above embodiment of the first cavity 112 to implement the structural technical solution of the second cavity 122, which will not be described here.

[0055] In some embodiments, a third cavity 123 is provided in the first cross beam 11 and the second cross beam 12 in communication, and a third drag chain 33 is located in the third cavity 123. The height of the third cavity 123 is greater than or equal to the turning radius of the third drag chain 33.

[0056] Through the above structure, the third cavity 123 communicates the interiors of the first cross beam 11 and the second cross beam 12, so that the third drag chain 33 can be connected to the first cross beam 11 and the second cross beam 12 at the same time. When the first cross beam 11 and / or the second cross beam 12 rotates, since the height of the third cavity 123 is greater than or equal to the turning radius of the third drag chain 33, the third drag chain 33 has enough space to bend and flatten synchronously following the rotation of the first cross beam 11 and / or the second cross beam 12, so as to ensure that the cable provided in the third drag chain 33 can still be connected to the first cross beam 11 and the second cross beam 12.

[0057] Specifically, in the embodiment of the present application, the third cavity 123 communicates the interiors of the first cross beam 11 and the second cross beam 12, so that the third drag chain 33 in the third cavity 123 can be connected to the first cross beam 11 and the second cross beam 12 at the same time. At this time, the third drag chain 33 can be provided with a cable connected to the first cross beam 11 and the second cross beam 12 to support the work of other electronic elements in the first cross beam 11 and the second cross beam 12.

[0058] In some embodiments, the fixed end 331 of the third drag chain 33 is provided at one end of the third cavity 123 located in the first cross beam 11, and the movable end 332 of the third drag chain 33 is provided at one end of the third cavity 123 located in the second cross beam 12. The third drag chain 33 is configured to bend or flatten following the rotation of the first cross beam 11 and / or the second cross beam 12.

[0059] Through the above structure, the fixed end 331 and the movable end 332 of the third drag chain 33 are arranged inside the first cross beam 11 and the second cross beam 12 respectively, when the first cross beam 11 and the second cross beam 12 are rotated to the vertical upward direction, the movable end 332 of the third drag chain 33 is changed from the curved state to the flat state, so as to increase the expansion length of the third drag chain 33, and fill the horizontal distance between the end of the first cross beam 11 and the end of the second cross beam 12. When the first cross beam 11 and the second cross beam 12 are rotated to the horizontal direction, the movable end 332 of the third drag chain 33 is changed from the flat state to the curved state, so that the excess length part of the third drag chain 33 is curled and stored at this time.

[0060] Specifically, in the embodiment of the present application, the fixed end 331 of the third drag chain 33 is arranged on the side wall of the third cavity 123 located in the first cross beam 11, and the movable end 332 of the third drag chain 33 is arranged on the side wall of the third cavity 123 located in the second cross beam 12, and the movable end 332 of the third drag chain 33 is in a curved semicircular shape. In other embodiments, the fixed end 331 of the third drag chain 33 can also be arranged on one side of the third cavity 123 located in the second cross beam 12, and the movable end 332 can be arranged on one side of the third cavity 123 located in the first cross beam 11, which is not limited. When the first cross beam 11 and the second cross beam 12 are horizontally arranged for work, the third drag chain 33 should be contracted, and when the first cross beam 11 and the second cross beam 12 are vertically placed for storage, the third drag chain 33 should be expanded to keep the cable connection of the first cross beam 11 and the second cross beam 12. For example, the distance from the fixed end 331 of the third drag chain 33 to the proximal end of the first cross beam 11 is L1, the distance from the movable end 332 of the third drag chain 33 to the proximal end of the second cross beam 12 is L2, when the first cross beam 11 and the second cross beam 12 are horizontally placed, the length of the third drag chain 33 in the horizontal direction should be L1+L2, and the remaining length is folded. When the first cross beam 11 and the second cross beam 12 are vertically placed, the horizontal distance between the proximal end 113 of the first cross beam 11 and the proximal end 123 of the second cross beam 12 is L3, and the total length of the third drag chain 33 is L1+L2+L3.

[0061] In some embodiments, a reinforcing belt (not shown in the figure) is arranged in the third drag chain 33, and the reinforcing belt is made of a ductile material.

[0062] Through the above structure, when the third drag chain 33 is bent or expanded following the rotation of the first cross beam 11 and / or the second cross beam 12, the deformation range of the third drag chain 33 is large, and by arranging the reinforcing belt with ductility in the third drag chain 33, the ductility of the third drag chain 33 can be improved, so as to improve the deformation recovery ability of the third drag chain 33, and meet the contraction requirement following the rotation of the first cross beam 11 and / or the second cross beam 12.

[0063] Specifically, in the embodiment of the present application, since the third drag chain 33 is bent at the proximal end 113 of the first crossbeam 11 and the proximal end 123 of the second crossbeam 12, and the bending radius is large, the toughness requirement of the third drag chain 33 is higher, so that the third drag chain 33 can follow the synchronous bending during the rotation of the first crossbeam 11 and / or the second crossbeam 12. Thus, the effect can be achieved by arranging the reinforcing belts in the third drag chain 33. More specifically, in the embodiment of the present application, the reinforcing belts are steel belts, the number of the steel belts is three, and the thickness of each steel belt is 0.4 mm. It should be noted that the above is only a demonstrative description, and those skilled in the art can adjust the type, number, and specification and size of the connecting belts according to the actual implementation of the technical solutions.

The diagnostic instrument can be a tablet diagnostic instrument, so as to be convenient for carrying and transportation, and the diagnostic instrument is in communication connection with the AVM laser instrument, so as to receive the vehicle image data photographed by the AVM laser instrument.
