Description

Technical Field

[0001] This invention relates to the field of vehicle handling technology, and more particularly to a transfer device. Background Technology

[0002] With the development of new energy vehicles, the driving range of electric vehicles is constantly increasing, and the corresponding power battery pack size is also getting larger and larger. Generally, the conversion equipment for new energy vehicles is in the form of supporting the skirt or supporting the bottom plate.

[0003] After the power battery assembly and the power battery guard plate are completed, the space under the vehicle body is extremely limited. The side skirts are often obscured by the battery envelope, making it difficult to find another set of front and rear side skirt support points during vehicle transition. Due to the limited space, this can even lead to quality problems such as battery impact and damage to the underbody guard plate. Even if a transition device is made that meets the requirements, there is serious interference between the two devices during the transition process, making the transition difficult. In addition, different models have different side skirt lengths, requiring multiple stop positions or positioning mechanisms, resulting in wasted assembly space, complex mechanisms, and low reliability. This can easily cause the vehicle body to tip over or the side skirts to deform during the transition.

[0004] Therefore, there is an urgent need for a switching device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a transfer device that can transport a vehicle by lifting the wheels and maintain the relative stability of the wheels and the transport fixture.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Adapter equipment, including:

[0008] Adjustment brackets, two of which are symmetrically arranged in the left-right direction;

[0009] The arm support assembly includes an arm support frame, an arm support, a rotating connecting plate, a rotating gear shaft, and a stabilizing connecting plate. The arm support frame is connected to the adjusting bracket. Two arm supports are provided in the front-rear direction and are rotatably connected to the arm support frame via the rotating gear shaft. The arm supports have a working state where they are placed parallel to the left-right direction and an idle state where they are placed perpendicular to the left-right direction. The rotating connecting plate is slidably connected to the arm support frame and can drive the arm support to rotate via the rotating gear shaft. The stabilizing connecting plate is slidably connected to the arm support frame. The arm support includes a supporting part and an abutting part, which are located on the radial sides of the rotating gear shaft, respectively. The supporting part is used to support the wheel on the lower side, and the stabilizing connecting plate can abut against the abutting part to maintain the working state of the arm support.

[0010] The aforementioned arm assemblies are provided in multiple ways, and each of the aforementioned adjusting brackets is equipped with at least two of the aforementioned arm assemblies along the aforementioned front-back direction. The aforementioned adjusting brackets are capable of adjusting the relative positions of the aforementioned arm assemblies with respect to the ground in the aforementioned front-back direction and vertical direction.

[0011] As a preferred technical solution of the above-mentioned adapter, the axis of the rotary gear shaft is parallel to the above-mentioned vertical direction, the rotary connecting plate and the above-mentioned stable connecting plate are parallel, and both can slide relative to the above-mentioned arm frame in the above-mentioned horizontal direction.

[0012] As a preferred technical solution of the above-mentioned adapter, the support part is rotatably connected with a plurality of first guide wheels. When the arm support is in the above-mentioned use state, the axial direction of the first guide wheels is parallel to the left and right directions.

[0013] As a preferred technical solution of the above-mentioned adapter, the abutting part is rotatably connected to a second guide wheel, the axial direction of the second guide wheel is parallel to the above-mentioned vertical direction, and the stabilizing connecting plate can slide relative to the second guide wheel.

[0014] As a preferred technical solution of the above-mentioned adapter, the adjustment bracket includes a first slide, a second slide, and a third slide. The first slide is installed in a one-to-one correspondence with the arm assembly. The second slide is provided with a second guide rail parallel to the front-back direction. The first slide can slide or lock relative to the second slide along the second guide rail. The third slide includes a third guide rail parallel to the up-down direction. The second slide can slide or lock relative to the third slide along the third guide rail.

[0015] As a preferred technical solution of the above-mentioned transfer device, the third guide rail is symmetrically arranged at the opposite ends of the third slide in the front-back direction. The third slide is equipped with a lifting motor, which is connected to two lifting gear shafts respectively through a splitter box. The second slide is symmetrically arranged with two lifting rack rails and multiple first limit wheel sets in the front-back direction. The lifting rack rails are arranged along the up-down direction and mesh with the lifting gear shafts. The first limit wheel sets can be clamped on the opposite sides of the third guide rail along the axial direction of the lifting gear shafts.

[0016] As a preferred technical solution of the above-mentioned transfer device, the third guide rail is fixed with a gear shaft bracket, and the gear part of the lifting gear shaft is mounted on the gear shaft bracket.

[0017] As a preferred technical solution of the above-mentioned transfer device, it also includes a track assembly, which has two tracks symmetrically arranged in the left-right direction and both fixed relative to the ground. The track assembly extends in the front-back direction, and the third slide can slide or lock relative to the ground along the track assembly.

[0018] As a preferred technical solution of the above-mentioned transfer device, the track assembly includes a moving track, upper and lower limit tracks, and a moving rack track. The moving track, upper and lower limit tracks, and moving rack track are arranged in parallel and relatively fixed. Two moving tracks are symmetrically arranged on the left and right sides of the upper and lower limit tracks. The bottom of the third slide is rotatably connected to a bearing wheel, a second limit wheel set, and a moving gear. The bearing wheel is slidably connected to the moving track. The upper and lower limit tracks have grooves on their left and right sides. The second limit wheel set is at least partially slidably inserted into the grooves. The moving gear meshes with the moving rack track.

[0019] As a preferred technical solution for the aforementioned transfer equipment, it also includes a detection mechanism, which is used to obtain the vehicle's position information in the aforementioned forward and backward directions.

[0020] Beneficial effects of this invention:

[0021] Furthermore, when the cantilever arm support is in use, it forms a cantilever beam structure. When the cantilever arm assembly supports the wheel from below, a groove is formed between the two cantilever arm supports, with the wheel portion located within the groove. The force exerted by the wheel and vehicle on the cantilever arm support can be decomposed into a first force that causes both cantilever arm supports to bend downwards together, and a second force that causes the two cantilever arm supports to move away from each other in the front-rear direction. Among these, the force parallel to the axis of the rotating gear shaft has a relatively small impact on the cantilever arm support due to the connection between the rotating gear shaft and the cantilever arm frame. However, the axial force perpendicular to the rotating gear shaft can easily cause the cantilever arm support to rotate further relative to the cantilever arm frame, potentially causing the gear to deflect from the cantilever arm support. To prevent slippage, this embodiment also includes a stabilizing connecting plate that slides relative to the arm support frame. The stabilizing connecting plate has two relative positions: a third position and a fourth position. When in the third position, the stabilizing connecting plate slides away from the arm support in its sliding direction. When in the fourth position, the stabilizing connecting plate abuts against the abutting part of the arm support. Since the abutting part and the supporting part of the arm support are located on opposite sides of the rotating gear shaft, forming a lever structure with the rotating gear shaft as the fulcrum, the force exerted by the stabilizing connecting plate on the abutting part and the force exerted by the wheel on the supporting part act in opposite directions around the rotating gear shaft, thus canceling each other out. This allows the arm support to maintain its operational state and prevents deformation. In the idle state, the arm assembly is in its initial position, which is close to the ground in the vertical direction. When a vehicle needs to be moved, the arm assembly adjusts its spacing in the front-to-back direction to accommodate the different wheelbases of various vehicle models. Then, the arm assembly switches from an idle state to an active state, with the arm supports extending laterally. The vehicle drives between the two adjusting brackets, positioning itself on either side with at least two wheels resting on the arm supports, and each wheel positioned on two supports of the same arm assembly. The adjusting brackets then lift the arm assembly vertically, raising the vehicle off the ground, and finally move the arm assembly back-to-back to complete the vehicle transport.

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0044] like Figures 1 to 10As shown, the present invention provides a transfer device, including an adjusting bracket and a clamping arm assembly 100. Two adjusting brackets are symmetrically arranged in the left-right direction (X). The clamping arm assembly 100 includes a clamping arm frame 110, a clamping arm support 120, a rotating connecting plate 130, a rotating gear shaft 140, and a stabilizing connecting plate 150. The clamping arm frame 110 is connected to the adjusting bracket. Two clamping arm supports 120 are arranged in the front-back direction (Y), each rotatably connected to the clamping arm frame 110 via the rotating gear shaft 140. The clamping arm supports 120 have a used state placed parallel to the left-right direction (X) and an idle state placed perpendicular to the left-right direction (X). The rotating connecting plate 130 is slidably connected to the clamping arm frame 110 and is capable of... The rotating gear shaft 140 drives the arm support 120 to rotate. The stabilizing connecting plate 150 is slidably connected to the arm frame 110. The arm support 120 includes a support part and an abutment part, which are located on the radial sides of the rotating gear shaft 140, respectively. The support part is used to support the wheel on the lower side. The stabilizing connecting plate 150 can abut against the abutment part to maintain the working state of the arm support 120. Multiple arm assemblies 100 are provided, and each adjusting bracket has at least two arm assemblies 100 installed along the front-rear direction Y. The adjusting bracket can adjust the relative position of the arm assembly 100 with respect to the ground in the front-rear direction Y and the vertical direction Z.

[0045] Specifically, the rotating gear shaft 140 includes an optical shaft segment and a gear segment. Along the axial direction, the gear segment is located between two optical shaft segments. The optical shaft segment of the rotating gear shaft 140 is rotatably connected to the arm support frame 110, and the arm support 120 is fixed to the rotating gear shaft 140. The rotating connecting plate 130 is slidably connected to the arm support frame 110, and the moving direction of the rotating connecting plate 130 is perpendicular to the axis of the rotating gear shaft 140. The rotating connecting plate 130 has teeth on opposite sides, which can mesh with the gear segment of the rotating gear shaft 140. The rotating connecting plate 130 has a first position and a second position relative to the arm support frame 110. When it is in the first position, the arm support 120 is in an idle state, and when it is in the second position, the arm support 120 is in a working state.

[0046] Furthermore, when the arm support 120 is in use, it forms a cantilever beam structure. When the arm assembly 100 supports the wheel from below, a groove is formed between the two arm supports 120, with the wheel portion located within the groove. The force exerted by the wheel and vehicle on the arm support 120 can be decomposed into a first force that causes the two arm supports 120 to bend downwards together, and a second force that causes the two arm supports 120 to move away from each other in the front-rear direction Y. Among these, the force parallel to the axis of the rotating gear shaft 140 has a relatively small impact on the arm support 120 due to the connection between the rotating gear shaft 140 and the arm frame 110. However, the axial force perpendicular to the rotating gear shaft 140 can easily cause the arm support 120 to rotate further relative to the arm frame 110, potentially leading to the gear slipping off the arm support 120. To address this issue, this embodiment also includes a stabilizing connecting plate 150 that slides relative to the arm support 110. The stabilizing connecting plate 150 has two relative positions to the arm support 110: a third position and a fourth position. When the stabilizing connecting plate 150 is in the third position, it slides away from the arm support 120. When the stabilizing connecting plate 150 is in the fourth position, it abuts against the abutting portion of the arm support 120. Since the abutting portion and the supporting portion of the arm support 120 are located on opposite sides of the rotating gear shaft 140, forming a lever structure with the rotating gear shaft 140 as the fulcrum, the force exerted by the stabilizing connecting plate 150 on the abutting portion and the force exerted by the wheel on the supporting portion act in opposite directions around the rotating gear shaft 140, thus canceling each other out. This allows the arm support 120 to maintain its working state and prevents deformation.

[0047] It should be noted that when the arm support assembly 100 is in use, the distance between the support portions of its two arm supports 120 in the front-rear direction Y is less than the diameter of the wheel.

[0048] When idle, the arm assembly 100 is in its starting position, close to the ground in the vertical direction Z. When a vehicle needs to be moved, the arm assembly 100 adjusts its spacing in the longitudinal direction Y to accommodate the wheelbase of different vehicle models. Subsequently, the arm assembly 100 switches from the idle state to the active state, and the arm support 120 extends in the lateral direction X. The vehicle drives between the two adjusting brackets, with at least two wheels on each side of the vehicle in the lateral direction X, and each wheel resting on two arm supports 120 of the same arm assembly 100. The adjusting brackets then lift the arm assembly 100 in the vertical direction Z, raising the vehicle off the ground, and then move the arm assembly 100 in the longitudinal direction Y to complete the vehicle movement.

[0049] Since multiple arm assemblies 100 on the same adjustment bracket are arranged sequentially along the front-rear direction Y, the starting position of each arm assembly 100 is different.

[0050] Optionally, the axis of the rotating gear shaft 140 is parallel to the vertical direction Z, the rotating connecting plate 130 and the stabilizing connecting plate 150 are parallel, and they can both slide relative to the arm frame 110 in the horizontal direction X.

[0051] Specifically, in this embodiment, when the rotating connecting plate 130 is in the first position, the rotating connecting plate 130 is away from the arm support 120 in the left-right direction X. When the stabilizing connecting plate 150 is in the third position, the stabilizing connecting plate 150 is away from the arm support 120 in the left-right direction X. The protrusions of the rotating connecting plate 130 are arranged on opposite sides in the front-back direction Y. In use, the rotating connecting plate 130 is driven first to put the arm support 120 into use state, and then the stabilizing connecting plate 150 is driven to be positioned between the two abutting parts. When the support part is subjected to a force that separates from each other in the front-back direction Y, the two abutting parts tend to move closer to each other in the front-back direction Y, squeezing the stabilizing connecting plate 150. The stabilizing connecting plate 150 supports the two abutting parts by its own structural strength.

[0052] Specifically, the arm frame 110 is also fixed with a first directional guide rail 160 and a second directional guide rail 170. The rotating connecting plate 130 is slidably connected to the first directional guide rail 160, and the stabilizing connecting plate 150 is slidably connected to the second directional guide rail 170. In this way, the moving direction of the rotating connecting plate 130 and the stabilizing connecting plate 150 is more stable.

[0053] Furthermore, the arm frame 110 is equipped with a first drive motor 180 and a second drive motor 190. The first drive motor 180 is used to drive the rotating connecting plate to switch and lock between its first and second positions, and the second drive motor 190 is used to drive the stabilizing connecting plate 150 to switch and lock between its third and fourth positions.

[0054] Optionally, the output end of the first drive motor 180 is connected to one end of the crankshaft, and the rotating connecting plate 130 has an insertion slot along the front-rear direction Y. The other end of the crankshaft is slidably inserted into the insertion slot. The axes of both ends of the crankshaft are parallel to the vertical direction Z and do not coincide. Thus, when the first drive motor 180 drives the crankshaft to rotate, the other end of the crankshaft slides in the insertion slot and can drive the rotating connecting plate 130 to move along the left-right direction X.

[0055] The transmission method between the second drive motor 190 and the stabilizing connecting plate 150 is largely compatible with the transmission method between the first drive motor 180 and the rotating connecting plate 130, and will not be described in detail here.

[0056] In other embodiments, the axis of the rotating gear shaft 140 is parallel to the front-rear direction Y, and when the arm support 120 switches from the use state to the idle state, its support part swings upward.

[0057] Optionally, the support is rotatably connected to multiple first guide wheels 123. When the arm support 120 is in use, the axial direction of the first guide wheels 123 is parallel to the left-right direction X. In this way, the first guide wheels 123 can reduce the friction between the wheel and the arm support 120, and because the first guide wheels 123 make it easier for the wheel to slide relative to the arm support 120, under the action of the vehicle's gravity, the wheel is more likely to be centered between the two arm supports 120.

[0058] Optionally, a second guide wheel 124 is rotatably connected to the abutment portion. The axis of the second guide wheel 124 is parallel to the vertical direction Z, and the stabilizing connecting plate 150 can slide relative to the second guide wheel 124. In this way, the friction between the stabilizing connecting plate 150 and the abutment portion can be reduced by the second guide wheel 124, and the stabilizing connecting plate 150 can be more easily inserted between the two abutment portions.

[0059] Optionally, the adjustment bracket includes a first slide 200, a second slide 300, and a third slide 400. The first slide 200 is installed in a one-to-one correspondence with the arm assembly 100. The second slide 300 is provided with a second guide rail 310 parallel to the front-rear direction Y. The first slide 200 can slide or lock relative to the second slide 300 along the second guide rail 310. The third slide 400 includes a third guide rail 410 parallel to the vertical direction Z. The second slide 300 can slide or lock relative to the third slide 400 along the third guide rail 410.

[0060] Specifically, multiple first slides 200 are slidably arranged on the second slide 300. Two adjacent first slides 200 can slide or lock relative to each other in the front-rear direction Y to adapt to the front and rear wheelbases of different vehicle models. By sliding or locking the second slide 300 relative to the third slide 400 in the up-down direction Z, multiple arm assemblies 100 located on the same side in the left-right direction X can move synchronously.

[0061] Specifically, the first slide 200 is fixed with a fourth drive motor 210, which drives the first slide 200 to move relative to the second slide 300. In this embodiment, the fourth drive motor 210 uses a lead screw and slider structure for transmission. Its specific structure is existing technology and will not be described in detail here.

[0062] Optionally, the third guide rail 410 is symmetrically arranged at opposite ends of the third slide 400 in the front-back Y direction. The third slide 400 is equipped with a lifting motor 420, which is connected to two lifting gear shafts respectively through a one-to-two transfer case 430. The second slide 300 is symmetrically arranged with two lifting rack rails 320 and multiple first limit wheel sets 330 in the front-back Y direction. The lifting rack rails 320 are arranged in the up-down Z direction and mesh with the lifting gear shafts. The first limit wheel sets 330 can be clamped on opposite sides of the third guide rail 410 along the axial direction of the lifting gear shafts.

[0063] Specifically, a lifting motor base 490 is fixed in the middle of the third slide 400, and a lifting motor 420 is mounted on the lifting motor base 490. The lifting motor 420 can drive two lifting gear shafts to rotate simultaneously through a one-to-two splitter box 430. The axial direction of the lifting gear shaft is parallel to the front-to-back direction Y, and the gear part of the lifting gear shaft meshes with the lifting rack rail 320 for transmission. When the lifting motor 420 drives the second slide 300 to move in the up-down direction Z through the lifting gear shaft, since the gear rack mechanism is prone to axial misalignment, a first limiting wheel set 330 is also provided in this embodiment. The first limiting wheel set 330 clamps the third guide rail 410 on both sides of the axial direction of the lifting gear shaft and can slide relative to the third guide rail 410.

[0064] Specifically, the first and second transfer case 430 is driven by the lifting gear shaft through the universal joint 440.

[0065] Furthermore, the connection between the universal joint 440 and the lifting gear shaft is secured by a flange, thereby enhancing the reliability of their connection. Furthermore, the lifting gear shaft is installed within the housing, and the flange is also located within the housing. The gear portion of the lifting gear shaft can be exposed from the housing for meshing with the lifting rack and pinion rail 320. The housing design reduces contact between the lifting gear shaft and the flange and dust.

[0066] When the lifting gear shaft meshes with the lifting rack rail 320, the gear part of the lifting gear shaft is the main force point. In order to maintain the stable transmission of the lifting gear shaft, in this embodiment, the third guide rail 410 is fixed with a gear shaft bracket 450, and the gear part of the lifting gear shaft is installed on the gear shaft bracket 450.

[0067] Optionally, the transfer device also includes a track assembly 500. Two track assemblies 500 are symmetrically arranged in the left-right direction (X) and are both fixed relative to the ground. The track assembly 500 extends in the front-back direction (Y). The third slide 400 can slide or lock relative to the ground along the track assembly 500. In use, after the arm assembly 100 supports the wheels, when transporting a vehicle in the front-back direction (Y), if the arm assembly 100 is directly driven to move, the starting timing of multiple arm assemblies 100 is difficult to keep in sync. Therefore, when the arm assembly 100 supports the wheels, it is in a locked state, and its relative position to the second slide 300 no longer changes. Synchronous movement of the arm assembly 100 is achieved by moving the third slide 400.

[0068] Optionally, the track assembly 500 includes a moving track 510, upper and lower limit tracks 520, and a moving rack track 530. The moving track 510, upper and lower limit tracks 520, and moving rack track 530 are arranged in parallel and relatively fixed. The moving track 510 has two tracks symmetrically arranged on the left and right sides of the upper and lower limit tracks 520. The bottom of the third slide 400 is rotatably connected to a bearing wheel 460, a second limit wheel set 470, and a moving gear 480. The bearing wheel 460 is slidably connected to the moving track 510. The upper and lower limit tracks 520 have grooves on their left and right sides. The second limit wheel set 470 is at least partially slidably inserted into the groove. The moving gear 480 meshes with the moving rack track 530.

[0069] Specifically, the moving track 510 is fixed to the ground by the foot 540, the axis of the bearing wheel 460 is parallel to the left-right direction X, the axis of the second limiting wheel set 470 is parallel to the left-right direction X, the bearing wheel 460 is in contact with the upper end surface of the moving track 510, and the second limiting wheel set 470 is inserted into the slide groove of the upper and lower limiting tracks 520, and can slide and connect with the side walls of the upper and lower sides of the slide groove. By rotating the transfer gear 480, the third slide 400 is driven to move relative to the track assembly 500.

[0070] Limiting blocks 550 are set at both ends of the displacement track to limit the movement range of the third slide 400 in the forward and backward direction Y.

[0071] Specifically, the third slide 400 is equipped with a third drive motor, which can drive the transfer gear 480 to rotate.

[0072] Optionally, the transfer device also includes a detection mechanism, which is used to acquire the vehicle's position information in the forward and backward Y direction. In this way, by acquiring the vehicle's position information through the detection mechanism, it is ensured that the wheels are stably positioned between the two arm supports 120 when the second slide 300 is lifted.
