Description

Technical Field

[0001] This utility model belongs to the field of automobile handling technology, and in particular relates to an automobile handling device and a three-dimensional parking garage. Background Technology

[0002] In recent years, with the rapid innovation and continuous development of science and technology, various new types of cars have emerged at a rapid pace, greatly enriching the market. This has not only changed people's travel methods, but also promoted the rapid development of the intelligent parking industry.

[0003] Currently, existing automated parking systems primarily use two types of automated guided vehicles (AGVs): platform-type and mother-daughter type. Platform-type AGVs require transporting car platforms back and forth, resulting in low efficiency and limited application scenarios. Mother-daughter type AGVs require coordination with a vehicle transporter, which relies on tracks for movement. Furthermore, the AGVs themselves are relatively large, leading to poor flexibility and adaptability in car retrieval, resulting in long retrieval times. Therefore, designing a new car transporter is essential. Utility Model Content

[0004] In view of this, it is necessary to provide a car transporter and a multi-level parking garage that are small in size and have high vehicle retrieval efficiency.

[0005] A car transporter, comprising:

[0006] Frame;

[0007] Multiple drive wheel mechanisms are disposed in the area where the vehicle frame is located and are connected to the vehicle frame;

[0008] Two clamping arm mechanisms are mounted on the vehicle frame for clamping the front and rear wheels of the vehicle. At least one of the clamping arm mechanisms is capable of moving relative to the vehicle frame along the length of the vehicle frame to adapt to different vehicle wheelbases.

[0009] A wheelbase adjustment mechanism, corresponding to at least one of the two clamping arm mechanisms, is mounted on the corresponding clamping arm mechanism and is used to control the movement of the corresponding clamping arm mechanism on the vehicle frame to adjust the distance between the two clamping arm mechanisms.

[0010] The control module is installed inside the vehicle frame and is electrically connected to the drive wheel mechanism, the two clamping arm mechanisms and the wheelbase adjustment mechanism.

[0011] Understandably, mounting the two clamping arm mechanisms that hold the front and rear wheels of a car onto the vehicle frame allows the entire clamping arm mechanism to be housed within the frame area when folded. This makes the car transporter compact and better suited for special scenarios. Furthermore, the car transporter can automatically adjust the distance between the two clamping arm mechanisms via a wheelbase adjustment mechanism. This allows the car transporter to handle cars with different wheelbases and simplifies the car retrieval process, reducing retrieval time and improving work efficiency.

[0012] In one embodiment, a chain is mounted on the frame, the chain extending along the length of the frame and passing through the corresponding clamping arm mechanism;

[0013] The wheelbase adjustment mechanism includes a drive sprocket and a first rotary drive component. The drive sprocket meshes with the chain and is connected to the first rotary drive component in a transmission manner.

[0014] The control module is electrically connected to the first rotary drive component. The control module acquires the vehicle wheelbase information and outputs the vehicle wheelbase information to the first rotary drive component to control the first rotary drive component to work so that the corresponding clamping arm mechanism moves on the frame to the distance between the two clamping arm mechanisms to match the vehicle wheelbase corresponding to the vehicle wheelbase information.

[0015] Understandably, the meshing between the drive sprocket on the moving clamping arm mechanism and the chain on the frame allows the wheelbase adjustment mechanism to utilize the action and reaction forces between the drive sprocket and the chain to achieve the movement of the clamping arm mechanism on the frame. This satisfies the vehicle transporter's need to adjust the distance between the two clamping arm mechanisms.

[0016] In one embodiment, the clamping arm mechanism includes four robotic arms, a second rotary drive, and four rack assemblies. Each of the four robotic arms is provided with an arc-shaped gear, and the four rack assemblies correspond one-to-one with the four arc-shaped gears. The arc-shaped gears can be connected to the second rotary drive through the corresponding rack assemblies.

[0017] The control module is electrically connected to the second rotary drive. The control module acquires the vehicle wheelbase information and outputs the vehicle wheelbase information to the second rotary drive to control the operation of the second rotary drive, so as to drive the four robotic arms to rotate off the vehicle frame.

[0018] Understandably, the second rotary drive unit can control the four robotic arms to rotate out of the frame based on the vehicle wheelbase information transmitted by the control module. This allows the car transporter to automatically drive the two clamping arm mechanisms to clamp the front and rear wheels of the car after entering under the car chassis, thus improving the working efficiency of the car transporter.

[0019] In one embodiment, the rack assembly includes a rack and a ball screw, the rack being threadedly connected to the ball screw and meshing with a corresponding arc-shaped gear;

[0020] The clamping arm mechanism further includes a synchronous transmission assembly, through which the four ball screws are connected to the second rotary drive component.

[0021] It is understandable that using a synchronous transmission assembly to realize the transmission connection between the second rotary drive and the four ball screws allows each gripper mechanism to use only one second rotary drive to drive the two sets of robotic arms to grip the car tire. This simplifies the structure of the gripper mechanism and reduces costs, while also ensuring the consistency of the movement of the four racks to meet the usage requirements of driving the two sets of robotic arms.

[0022] In one embodiment, the drive wheel mechanism includes two drive wheel sets, a connecting frame, a connecting shaft, and a slewing support assembly. The connecting frame is disposed between the two drive wheel sets and connected to each of the drive wheel sets. Furthermore, the connecting frame is rotatably mounted on the slewing support assembly via the connecting shaft, so that the two drive wheel sets can swing about the connecting shaft as the rotation center line.

[0023] The drive wheel mechanism also includes an encoder, which meshes with the ring gear on the rotary support assembly via an encoder gear to detect the rotation angle of the drive wheel assembly and adjust the movement direction of the drive wheel mechanism.

[0024] The control module is electrically connected to the two drive wheel sets respectively, and is used to control the rotational speed of the drive wheels on each drive wheel set respectively.

[0025] Understandably, since the two drive wheel sets in this drive wheel mechanism can rotate around the connecting shaft as the rotation center line, the drive wheel mechanism can swing left and right when walking. This reduces the vibration amplitude of the car transporter when walking on uneven or non-parallel surfaces, so that the car transporter has good adaptability to environments with poor surface flatness, and ensures that the two drive wheel mechanisms support the frame and avoid extreme load conditions.

[0026] In one embodiment, the drive wheel mechanism further includes a drive mounting plate and a drive floating assembly, wherein the slewing support assembly is mounted on the drive mounting plate via the drive floating assembly, so that the slewing support assembly can be adjusted in position in the height direction of the frame;

[0027] The drive mounting plate is mounted on the vehicle frame;

[0028] The drive floating assembly includes a guide shaft, an elastic element, and a floating pressure plate. The guide shaft is fixedly mounted on the slewing support assembly and slidably connected to the drive mounting plate. The floating pressure plate is disposed above the drive mounting plate in the height direction of the vehicle frame and is connected and fixed to the drive mounting plate. The elastic element is partially disposed inside the guide shaft and abuts against the lower cover of the guide shaft and the floating pressure plate in a pre-compressed manner.

[0029] It is understandable that the driving floating component is used to adjust the height of the driving wheel mechanism during travel, which ensures that the driving wheel on the driving wheel assembly is always in contact with the traveling surface and prevents the driving wheel from spinning freely.

[0030] In one embodiment, the number of drive wheel mechanisms is configured to be multiple, and the multiple drive wheel mechanisms are disposed on both sides of the frame in the length direction of the frame;

[0031] The vehicle transporter also includes an auxiliary support wheel mechanism, which is disposed between the two drive wheel mechanisms and connected to the vehicle frame.

[0032] It is understandable that the auxiliary support wheel mechanism is used to provide auxiliary support to the frame, thus preventing the frame from deforming under pressure when the car transporter is moving the car, and improving the load-bearing stability of the car transporter.

[0033] In one embodiment, the auxiliary support wheel mechanism includes:

[0034] Swing seat;

[0035] A load-bearing shaft is provided through the swing seat and rotatably connected to the swing seat;

[0036] A swing shaft is provided through the swing seat and rotatably connected to the swing seat. The swing shaft and the load-bearing shaft are staggered in the height direction of the frame, and the axial direction of the swing shaft is perpendicular to the axial direction of the load-bearing shaft.

[0037] Multiple support wheel assemblies are arranged on both sides of the swing seat along the axial direction of the swing shaft, and are respectively rotatably connected to the swing shaft;

[0038] The plurality of support wheel assemblies are capable of swinging about the swing axis as the rotation center line, and the plurality of support wheel assemblies are capable of swinging about the load-bearing axis through the swing seat.

[0039] Understandably, multiple support wheel assemblies can swing around mutually perpendicular load-bearing axes and swing axes as rotation center lines, so that when the auxiliary support wheel mechanism travels on uneven walking surfaces, the multiple support wheel assemblies can always be in contact with the walking surface. This ensures that the auxiliary support wheel mechanism plays an auxiliary support role for the frame, and also avoids the auxiliary support wheel mechanism affecting the movement of the car transporter on the walking surface.

[0040] In one embodiment, the auxiliary support wheel mechanism further includes a plurality of floating mounting seats, the load-bearing shaft being mounted on the plurality of floating mounting seats and circumferentially limited relative to the floating mounting seats;

[0041] The floating mounting base can be adjusted in position along the height of the vehicle frame under the drive of the load-bearing shaft.

[0042] It is understandable that using a floating mounting base to adjust the height of the auxiliary support wheel mechanism during travel ensures that the support wheel assembly is always in contact with the traveling surface and provides auxiliary support to the frame.

[0043] This application also provides a multi-level parking garage, including the aforementioned car transporter.

[0044] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0045] The car transporter and automated parking system claimed in this application utilize two clamping arm mechanisms that grip the front and rear wheels of a car, mounted on a vehicle frame. When the clamping arm mechanisms are folded, the entire assembly can be housed within the frame area, resulting in a compact car transporter that is better suited for specific scenarios. Furthermore, the car transporter can automatically adjust the distance between the two clamping arm mechanisms via a wheelbase adjustment mechanism. This allows the car transporter to handle vehicles with different wheelbases and simplifies the car retrieval process, reducing retrieval time and improving work efficiency.

[0065] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] It should be noted that when a component is said to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "located on" another component, it can be directly located on the other component or may have an intervening component. When a component is considered to be "fixed to" another component, it can be directly fixed to the other component or may have an intervening component.

[0067] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0068] like Figure 1 , Figure 2 As shown, the car transporter 100 claimed in this application specifically refers to an AGV trolley used in a multi-level parking garage for transporting / retrieving cars 200.

[0069] like Figure 3 , Figure 4As shown, the car transporter 100 provided in this application includes a frame 10, multiple drive wheel mechanisms 20, two clamping arm mechanisms 30, a wheelbase adjustment mechanism 40, and a control module 50. The multiple drive wheel mechanisms 20 are disposed within the area of ​​the frame 10 and connected to the frame 10. The two clamping arm mechanisms 30 are mounted on the frame 10 and are used to clamp the front and rear wheels of the car 200. At least one clamping arm mechanism 30 can move relative to the frame 10 along its length to adapt to different car wheelbases. The wheelbase adjustment mechanism 40 corresponds to at least one of the two clamping arm mechanisms 30 and is mounted on the corresponding clamping arm mechanism 30 to control the movement of the clamping arm mechanism 30 on the frame 10. The control module 50 is installed inside the frame 10 and is electrically connected to the drive wheel mechanisms 20, the two clamping arm mechanisms 30, and the wheelbase adjustment mechanism 40. Here, the two clamping arm mechanisms 30 on the car transporter 100 are configured with identical structures, and one of the clamping arm mechanisms 30 is capable of moving on the frame 10. It is understood that in other embodiments, the two clamping arm mechanisms 30 may also be configured to be movable on the frame 10, which will not be elaborated here.

[0070] As can be seen from the above, when the car transporter 100 is not gripping the tires of the car 200 with the robotic arm 31, the entire clamping arm mechanism 30 can be housed within the area of ​​the frame 10 when it is folded up. Specifically, it is placed against the long side of the frame 10, without occupying space in the length and width directions of the frame 10. This allows the car transporter 100 to be small in size and better adaptable to special scenarios. Furthermore, the car transporter 100 can automatically adjust the distance between the two clamping arm mechanisms 30 using the wheelbase adjustment mechanism 40. This makes the car transporter 100 suitable not only for transporting cars 200 with different wheelbases, but also for automatically adjusting the distance between the two clamping arm mechanisms 30 according to the signal received by the control module 50 during the process of the car transporter 100 driving under the car 200 to adapt to the car's wheelbase. This simplifies the car transporter 100's car retrieval action, shortens the car retrieval time, and improves work efficiency.

[0071] like Figure 3 , Figure 4 and Figure 10As shown, in one embodiment, a body slide rail 11 is provided on the frame 10; wherein, a roller 301 is rotatably connected to the movable clamping arm mechanism 30, specifically the roller 301 can be rotatably mounted on the clamping arm frame 310 of the clamping arm mechanism 30; wherein, the roller 301 is provided on the body slide rail 11, and the clamping arm mechanism 30 can move on the body slide rail 11 via the roller 301. That is to say, the clamping arm mechanism 30 can achieve movement by the movement of the roller 301 on the body slide rail 11, which can reduce the frictional resistance encountered by the clamping arm mechanism 30 when moving on the frame 10. Here, the number of body slide rails 11 is configured as two, and the two body slide rails 11 are arranged at intervals along the width direction of the frame 10, and the number of rollers 301 is configured as four, with two rollers 301 as a group, which are rotatably disposed on one of the body slide rails 11.

[0072] like Figure 3 , Figure 4 As shown, in one embodiment, the number of drive wheel mechanisms 20 is configured to be multiple. These multiple drive wheel mechanisms 20 are disposed on both sides of the frame 10 along its length, jointly supporting the frame 10 and enabling the car transporter 100 to move on the automated parking garage. Here, the number of drive wheel mechanisms 20 is configured to be two, with the two drive wheel mechanisms 20 having the same structure. It is understood that in other embodiments, the number of drive wheel mechanisms 20 may also be four, with two groups of two drive wheel mechanisms 20 arranged on both sides of the frame 10 along its length; this will not be elaborated upon here.

[0073] like Figures 5 to 7 As shown, in one embodiment, the drive wheel mechanism 20 includes two drive wheel sets 21, a connecting frame 22, a connecting shaft 23, and a slewing support assembly 24. The connecting frame 22 is disposed between the two drive wheel sets 21 and connected to each of the drive wheel sets 21. The connecting frame 22 is rotatably mounted on the slewing support assembly 24 via the connecting shaft 23. Specifically, the connecting shaft 23 is fixedly mounted on the slewing support assembly 24 after passing through the connecting frame 22, so that the two drive wheel sets 21 can swing about the connecting shaft 23 as the rotation center line. That is, the two drive wheel sets 21 swing left and right according to the uneven surface when walking, which can reduce the vibration amplitude of the car transporter 100 caused by the uneven surface when walking, so that the car transporter 100 has good adaptability to the environment with poor surface flatness, and ensures that the two drive wheel mechanisms 20 support the frame 10 and avoid extreme load conditions. Here, the two drive wheel sets 21 are electrically connected to the control module 50, so that the control module 50 can independently control the operation of each drive wheel set 21.

[0074] like Figure 5 , Figure 7As shown, in one embodiment, the drive wheel assembly 21 includes a drive wheel 211, a drive motor 212, and a drive reducer 213. The drive wheel 211 and the drive motor 212 are mounted on the drive reducer 213 and are respectively connected to the drive reducer 213 for transmission. When the drive wheel assembly 21 is working, the drive motor 212, under the reduction adjustment of the drive reducer 213, can drive the drive wheel 211 to rotate, thus enabling the drive wheel 211 to move. Here, the drive wheel 211 and the drive motor 212 are arranged at right angles, and the drive wheel assembly 21 is specifically connected and fixed to the connecting frame 22 through the drive reducer 213, allowing the two drive wheels 211 on the two drive wheel assemblies 21 to be symmetrically arranged. It should be noted that the drive motor 212 in the drive wheel assembly 21 is electrically connected to the control module 50.

[0075] It should be noted that, since the two sets of drive wheel groups 21, the two drive wheels 211, the two drive motors 212, and the two drive reducers 213 in the drive wheel mechanism 20 are arranged symmetrically with respect to the center line of the connecting shaft 23, and the drive reducers 213 in the two sets of drive wheel groups 21 are connected to each other by the connecting frame 22 to form an integral structure, this can play a stabilizing role. In conjunction with the slewing support assembly 24, it is more conducive to the steering motion of the drive wheel mechanism 20.

[0076] It is understandable that when the control module 50 controls the rotational speeds of the two drive wheels 211 in the drive wheel assembly 21 to be inconsistent, the steering function of the drive wheel assembly 21 can be achieved by utilizing the speed difference between the two drive wheels 211; therefore, such as Figure 5 As shown, the drive wheel mechanism 20 also includes an encoder 240 for detecting the rotation angle when the drive wheel mechanism 20 turns. Specifically, the slewing support assembly 24 includes a slewing support mounting base 241 and a slewing support 242 fixed to each other. An encoder gear 243 is connected to the encoder 240, and the encoder gear 243 meshes with the ring gear 2421 on the slewing support 242. Thus, when the two drive wheel sets 21 turn using the speed difference between the two drive wheels 211, the two drive wheel sets 21 can drive the slewing support 242 to rotate through the connecting frame 22 and the connecting shaft 23. Then, the meshing between the encoder gear 243 and the ring gear 2421 drives the encoder gear 243 to rotate, thereby triggering the encoder 240 and generating a feedback signal. This feedback signal is sent to the control module 50, so that the control module 50 can control the speed of the two drive wheels 211 according to the feedback signal transmitted by the encoder 240, and realize the steering control of the drive wheel mechanism 20. Here, the slewing support assembly 24 is connected and fixed to the connecting shaft 23 via the slewing support mounting base 241.

[0077] like Figures 5 to 7As shown, in one embodiment, the drive wheel mechanism 20 further includes a drive mounting plate 25 and a drive floating assembly 26; the drive mounting plate 25 is mounted on the frame 10; the slewing support assembly 24 is mounted on the drive mounting plate 25 via the drive floating assembly 26, so that the slewing support assembly 24 can be adjusted in position in the height direction of the frame 10. That is, the drive wheel mechanism 20 as a whole can be assembled with the drive mounting plate 25 as the assembly base, and the drive wheel mechanism 20 can be adjusted in height using the drive floating assembly 26 when walking, thus ensuring that the two drive wheels 211 on the drive wheel assembly 21 are always in contact with the walking surface and preventing the drive wheels 211 from spinning freely. Here, one end of the drive mounting plate 25 is rotatably connected to the frame 10 via a hinge 251. The other end of the drive mounting plate 25 rests against the frame 10, and the other two ends of the drive mounting plate 25 are placed on the frame 10 and then locked with bolts or other fasteners (not shown). This achieves the assembly connection between the drive mounting plate 25 and the frame 10. When the drive wheel mechanism 20 needs maintenance, the fasteners on the drive mounting plate 25 can be released from the frame 10, and then the drive wheel mechanism 20 can be flipped upwards via the hinge 251, thus avoiding the need to lift the entire car transporter 100. It should be noted that the drive wheel mechanism 20 has four drive floating components 26, which are arranged at the four corners of the drive mounting plate 25. The four drive floating components 26 are used together to achieve the lifting and lowering adjustment of the drive wheel assembly 21.

[0078] like Figure 7As shown, in one embodiment, the driving floating assembly 26 includes a guide shaft 261, an elastic element 262, and a floating pressure plate 263. The guide shaft 261 is fixedly mounted on the rotary support assembly 24 and slidably connected to the driving mounting plate 25. Specifically, a guide shaft mounting plate (not shown) is fixedly connected to the guide shaft 261. The guide shaft mounting plate is attached to the rotary support mounting seat 241 of the rotary support assembly 24, and then pressed and limited by a limiting plate 2611 fixed on the rotary support mounting seat 241; the floating pressure plate 26... 3. The guide shaft 261 is positioned above the drive mounting plate 25 in the height direction of the frame 10 and is connected and fixed to the drive mounting plate 25 via multiple connecting posts 264. An elastic element 262 is partially disposed within the guide shaft 261 and abuts against the lower cover 2612 and floating pressure plate 263 of the guide shaft 261 in a pre-compressed manner. This allows the slewing support assembly 24 to drive the guide shaft 261 to make vertical floating adjustments relative to the drive mounting plate 25 in the height direction of the frame 10 using the deformation of the elastic element 262. Here, the elastic element 262 can be configured as a spring, rubber sleeve, or other highly elastic component, which will not be elaborated further. It should be noted that a guide shaft bearing 252 is fixedly mounted on the drive mounting plate 25. The guide shaft 261 passes through the guide shaft bearing 252 and slides within it, guiding the guide shaft 261 to slide vertically relative to the guide shaft bearing 252.

[0079] like Figure 8 As shown, in one embodiment, the gripper arm mechanism 30 includes four robotic arms 31, a second rotary drive component 32, and four rack assemblies. Each of the four robotic arms 31 is equipped with an arc-shaped gear 311, and the four rack assemblies correspond one-to-one with the four arc-shaped gears 311. The arc-shaped gears 311 are connected to the second rotary drive component 32 via their respective rack assemblies. In other words, the rotation of the robotic arms 31 on the frame 10 can be achieved through gear and rack meshing. Here, the second rotary drive component 32 is configured as a motor, which can be mounted on the gripper arm frame 310 of the robotic arms 31 via a motor mounting plate 321. Furthermore, the control module 50 is electrically connected to the motor and is used to control the motor's start / stop. It is understood that in other embodiments, the second rotary drive component 32 may also be a rotary cylinder, rotary hydraulic cylinder, etc., which will not be elaborated upon here.

[0080] like Figure 8 , Figure 9As shown, in one embodiment, the rack assembly includes a rack 34 and a ball screw 331. The rack 34 is threaded to the ball screw 331 and meshes with a corresponding arc gear 311. This threaded connection between the ball screw 331 and the rack 34 allows the ball screw 331 to rotate, driving the rack 34 to move axially upwards along its axis. The meshing between the rack 34 and the corresponding arc gear 311 causes the arc gear 311 mounted on the robotic arm 31 to rotate, thereby rotating the robotic arm 31. The four ball screws 331 are connected to the second rotary drive component 32 via a synchronous transmission assembly 33. This allows the clamping arm mechanism 30 to rotate the four robotic arms 31 using only a second rotary drive 32, and to drive two sets of robotic arms 31 to grip the tires of the car 200. This simplifies the structure of the clamping arm mechanism 30, reduces costs, and ensures the consistency of the movement of the four racks 34 to meet the requirements of driving the two sets of robotic arms 31. Here, the synchronous transmission assembly 33 includes a first coupling 332, a second reducer 333, a synchronous shaft 334, and a second coupling 335. The two ball screws 331 corresponding to each set of robotic arms 31 can be connected by the first coupling 332; while the two sets of robotic arms 31 can be connected by the second reducer 333, the synchronous shaft 334, and the second coupling 335.

[0081] In this embodiment, the control module 50 is electrically connected to the second rotary drive 32. The control module 50 acquires the vehicle wheelbase information and outputs the vehicle wheelbase information to the second rotary drive 32 to control the operation of the second rotary drive 32, so as to drive the four robotic arms 31 to rotate out of the frame 10. This allows the car transporter 100 to automatically drive the two clamping arm mechanisms 30 to clamp the front and rear wheels of the car 200 after entering under the car chassis, which can improve the working efficiency of the car transporter 100.

[0082] It should be noted that the clamping arm mechanism 30 also includes a detection sensor for position detection of the robotic arm 31. The detection sensor is electrically connected to the control module 50 and is used to detect two positions of the robotic arm 31: the folded state when it is folded into the frame 10 and the working state when it is clamping the tire of the car 200. The detection sensor provides signal feedback on the working state of the clamping arm mechanism 30 accordingly. Here, a mounting plate 3021 is installed on one of the second reducers 333, and a photoelectric switch 302 is installed on the mounting plate 3021. The photoelectric switch 302 is used to detect whether the robotic arm 31 is in the working state. A trigger switch (not shown) is installed on the clamping arm frame 310 of the robotic arm 31. Correspondingly, a detection plate (not shown) is installed on one of the racks 34. The detection plate is used to detect whether the robotic arm 31 is in the folded state by matching the position of the rack 34 when the trigger switch is triggered with the position of the robotic arm 31 when it is in the folded state. It is understood that in other embodiments, the detection sensor described above can also provide feedback by detecting the two extreme positions of the rack 34, which will not be elaborated here.

[0083] like Figure 3 , Figure 4 , Figure 11 and Figure 12 As shown, in one embodiment, a chain 12 is mounted on the frame 10. The chain 12 extends along the length of the frame 10 and passes through the corresponding clamping arm mechanism 30. Specifically, both ends of the chain 12 can be fixed to the frame 10 via chain rods 121. Correspondingly, the wheelbase adjustment mechanism 40 includes a drive sprocket 41 and a first rotary drive member 42. The drive sprocket 41 is engaged with the chain 12 and is connected to the first rotary drive member 42 for transmission. This allows the wheelbase adjustment mechanism 40 to utilize the action and reaction forces between the drive sprocket 41 and the chain 12 to realize the movement of the clamping arm mechanism 30 on the frame 10, thus meeting the usage requirements of the car transporter 100 for adjusting the distance between the two clamping arm mechanisms 30. Here, the first rotary drive component 42 is configured as a motor, which is connected to the drive sprocket 41 via a third reducer 421. The third reducer 421 can be fixed to the clamping arm frame 310 via a mounting base 422. Furthermore, the control module 50 is electrically connected to the motor and is used to control the motor's start / stop. It is understood that in other embodiments, the first rotary drive component 42 may also be a rotary cylinder, a rotary hydraulic cylinder, etc., which will not be elaborated here.

[0084] like Figure 11 , Figure 12As shown, in one embodiment, the number of chains 12 is configured as two, and the two chains 12 are arranged at intervals along the width direction of the frame 10. Correspondingly, the number of drive sprockets 41 in the wheelbase adjustment mechanism 40 is configured as two, and the two drive sprockets 41 are connected by a connecting drive shaft 411. Each drive sprocket 41 meshes with one of the chains 12. Here, the first rotary drive member 42 is connected to one of the drive sprockets 41 by a third reducer 421. The third reducer 421 is then connected to one end of the drive shaft 411 by a rigid coupling 4111, and the other end of the drive shaft 411 is connected to the other drive sprocket 41 by a universal coupling 4112. This allows the wheelbase adjustment mechanism 40 to drive the two drive sprockets 41 to rotate on their respective chains 12 using only one first rotary drive member 42. It is understood that in other embodiments, the number of chains 12 may be one, three, four, or even more, which will not be elaborated here.

[0085] like Figure 12 As shown, in one embodiment, the wheelbase adjustment mechanism 40 further includes an idler sprocket 43. The idler sprocket 43 is disposed on one side of the drive sprocket 41 and meshes with the chain 12 to tension the chain 12. This ensures the stability of the meshing between the drive sprocket 41 and the chain 12, meeting the usage requirements of the clamping arm mechanism 30 moving on the frame 10. Here, each drive sprocket 41 corresponds to two idler sprockets 43, which are disposed on both sides of the corresponding drive sprocket 41 and rotatably connected to the mounting base 422.

[0086] As can be seen from the above, when the car transporter 100 of this application is working, the control module 50 can control the opening / closing of the first rotary drive 42 in the wheelbase adjustment mechanism 40 according to the signal transmitted by the three-dimensional garage, so as to adjust the distance between the two clamping arm mechanisms 30. In order to ensure that the clamping arm mechanism 30 can be accurately aligned with the tire of the car 200, in addition to controlling the distance between the two clamping arm mechanisms 30 according to the signal received by the control module 50, the car transporter 100 of this application can also detect the movement of the moving clamping arm mechanism 30 and generate a feedback signal by setting a position sensor (not shown). The feedback signal is used to transmit to the control module 50 and achieve a double insurance effect.

[0087] like Figure 4 , Figure 8 and Figure 9As shown, in one embodiment, a first detection sensor 101 is mounted on the frame 10. When the distance between the two clamping arm mechanisms 30 is at its maximum, the first detection sensor 101 can be triggered by the moving clamping arm mechanism 30 and generate a feedback signal. That is, the car transporter 100 can achieve automatic control when the distance between the two clamping arm mechanisms 30 is at its maximum. Here, the first detection sensor 101 is configured as a photoelectric switch, micro switch, proximity switch, etc., fixed on the frame 10; correspondingly, a first trigger plate 3101 is mounted on the clamping arm frame 310 of the clamping arm mechanism 30, and the clamping arm mechanism 30 can trigger the first detection sensor 101 with the first trigger plate 3101.

[0088] like Figure 3 , Figure 9 As shown, in one embodiment, a second detection sensor 102 is mounted on the frame 10. When the distance between the two clamping arm mechanisms 30 is at its minimum, the second detection sensor 102 can be triggered by the moving clamping arm mechanism 30 and generate a feedback signal. That is, the car transporter 100 can achieve automatic control when the distance between the two clamping arm mechanisms 30 is minimized. Here, the second detection sensor 102 is configured as a photoelectric switch, micro switch, proximity switch, etc., fixed on the frame 10; correspondingly, a second trigger plate 3102 is mounted on the clamping arm frame 310 of the clamping arm mechanism 30, and the clamping arm mechanism 30 can trigger the second detection sensor 102 with the second trigger plate 3102.

[0089] like Figure 3 , Figure 4 , Figure 8 and Figure 9 As shown, in one embodiment, a third detection sensor 103 is also installed on the clamping arm frame 310 of the moving clamping arm mechanism 30. The third detection sensor 103 can detect the position of the tire of the car 200 and generate a feedback signal. That is, the car transporter 100 can ensure that the clamping arm mechanism 30 automatically stops when it moves to a position that can clamp the tire of the car 200 by detecting when the clamping arm mechanism 30 is aligned with the tire of the car, so as to meet the usage requirements of the clamping arm mechanism 30 clamping the tire of the car. Here, the third detection sensor 103 is configured as a photoelectric switch, proximity switch, etc.

[0090] like Figure 3 , Figure 4 As shown, in one embodiment, the car transporter 100 further includes an auxiliary support wheel mechanism 60, which is disposed between the two drive wheel mechanisms 20 and connected to the vehicle frame 10. This allows the car transporter 100 to use the auxiliary support wheel mechanism 60 to provide auxiliary support for the vehicle frame 10, thus preventing deformation of the vehicle frame 10 due to pressure when the car transporter 100 is transporting the car 200, and improving the load-bearing stability of the car transporter 100.

[0091] like Figures 13 to 16 As shown, in one embodiment, the auxiliary support wheel mechanism 60 includes a swing seat 61, a load-bearing shaft 62, a swing shaft 63, and a plurality of support wheel assemblies 64. The load-bearing shaft 62 passes through the swing seat 61 and is rotatably connected to the swing seat 61. The swing shaft 63 passes through the swing seat 61 and is rotatably connected to the swing seat 61. The swing shaft 63 and the load-bearing shaft 62 are staggered in the height direction of the frame 10, and the axial direction of the swing shaft 63 is perpendicular to the axial direction of the load-bearing shaft 62. The plurality of support wheel assemblies 64 are arranged on both sides of the swing seat 61 along the axial direction of the swing shaft 63 and are rotatably connected to the swing shaft 63 respectively. The plurality of support wheel assemblies 64 can swing about the swing shaft 63 as the rotation center line, and the plurality of support wheel assemblies 64 can swing about the load-bearing shaft 62 through the swing seat 61. In other words, the multiple support wheel assemblies 64 can swing about the mutually perpendicular load-bearing shaft 62 and swing shaft 63 as rotational centers, ensuring that the multiple support wheel assemblies 64 are always in contact with the travel surface when the auxiliary support wheel mechanism 60 travels on an uneven travel surface. This ensures that the auxiliary support wheel mechanism 60 provides auxiliary support to the frame 10, and also prevents the auxiliary support wheel mechanism 60 from affecting the travel of the car transporter 100 on the travel surface. Here, the number of support wheel assemblies 64 is configured as two. It is understood that in other embodiments, the number of support wheel assemblies 64 may also be four or more even numbers, which will not be elaborated here.

[0092] like Figures 13 to 15 As shown, in one embodiment, the support wheel assembly 64 includes a support wheel mounting base 641 and a plurality of support wheel sets 642. The plurality of support wheel sets 642 are arranged on both sides of the swing shaft 63 along the axial direction of the load-bearing shaft 62 and are respectively connected to the support wheel mounting base 641. The support wheel mounting base 641 is provided with an extension protrusion 6411, which is rotatably connected to the swing shaft 63. Here, the support wheel assembly 64 has two support wheel sets 642, and each support wheel set 642 can be configured as a swivel wheel structure.

[0093] like Figures 13 to 15 , Figure 17As shown, in one embodiment, the auxiliary support wheel mechanism 60 further includes multiple floating mechanisms 65. These floating mechanisms 65 are arranged along the axial direction of the load-bearing shaft 62 on both sides of the load-bearing shaft 62 and are respectively connected to the load-bearing shaft 62 in a circumferentially limiting manner. That is, the support wheel assembly 64 in the auxiliary support wheel mechanism 60 supports the multiple floating mechanisms 65 through the support wheel mounting base 641 and the load-bearing shaft 62. Here, the number of floating mechanisms 65 is configured as two, arranged at the two ends of the load-bearing shaft 62 in the axial direction. It can be understood that in other embodiments, the number of floating mechanisms 65 may also be three, four, or even more, and these multiple floating mechanisms 65 may specifically be arranged at both ends of the load-bearing shaft 62 in the axial direction.

[0094] like Figure 15 , Figure 17 As shown, in one embodiment, the floating mechanism 65 includes a floating mounting base 651, on which a load-bearing shaft 62 is mounted and circumferentially limited relative to the floating mounting base 651. The floating mounting base 651 can be adjusted in position along the height of the frame 10 under the influence of the load-bearing shaft 62. This ensures that when the auxiliary support wheel mechanism 60 travels on uneven surfaces, the lifting and lowering adjustment of the floating mounting base 651 guarantees that the support wheel assembly 64 in the auxiliary support wheel mechanism 60 remains in contact with the travel surface, providing auxiliary support to the frame 10.

[0095] like Figure 17 As shown, in one embodiment, the floating mechanism 65 further includes a pressure block 652, which is threadedly connected to the floating mounting base 651 to press and limit the portion of the load-bearing shaft 62 located on the floating mounting base 651. The pressure block 652 has a first plane 6521, and the load-bearing shaft 62 has a second plane 621. The first plane 6521 and the second plane 621 are in contact, thereby achieving circumferential limiting of the load-bearing shaft 62 during assembly on the floating mounting base 651. It is understood that in other embodiments, the planar contact between the floating mounting base 651 and the load-bearing shaft 62 during assembly can also be used to achieve circumferential limiting of the assembly, or a bolt or other connecting component (not shown) can be directly threaded through the load-bearing shaft 62 and connected to the floating mounting base 651 to achieve circumferential limiting of the assembly. These details will not be elaborated upon here.

[0096] like Figure 17As shown, in one embodiment, the floating mechanism 65 further includes an elastic element 653. The elastic element 653 abuts against the floating mounting base 651 in a pre-compressed manner, providing a vertical elastic force to the floating mounting base 651. This satisfies the need for the floating mounting base 651 to be raised and lowered vertically under the drive of the load-bearing shaft 62. Specifically, when the support wheel assembly 642 is raised due to the protrusion of the traveling surface, the support wheel assembly 642, under the transmission of the support wheel mounting base 641 and the load-bearing shaft 62, can drive the floating mounting base 651 to compress the elastic element 653 and rise; conversely, when the support wheel assembly 642 is lowered due to the concavity of the traveling surface, the floating mounting base 651 will also descend. Here, the elastic element 653 is configured as a spring. It is understood that in other embodiments, the elastic element 653 may also be configured as a rubber sleeve or other highly elastic accessories, which will not be elaborated here.

[0097] like Figure 14 , Figure 17 As shown, in one embodiment, the floating mechanism 65 further includes an upper mounting plate 654, a lower mounting plate 655, and a connecting guide post 656. The connecting guide post 656 is disposed between the upper mounting plate 654 and the lower mounting plate 655, and is connected to both the upper mounting plate 654 and the lower mounting plate 655 respectively. Specifically, the three components can be connected and fixed with bolts. That is, the upper mounting plate 654, the connecting guide post 656, and the lower mounting plate 655 are connected to form the overall frame structure of the floating mechanism 65. Here, the upper mounting plate 654 extends outward relative to the lower mounting plate 655 in a direction away from the swing seat 61, and the extended portion of the upper mounting plate 654 is threadedly connected to the frame 10, thereby realizing the assembly connection of the auxiliary support wheel mechanism 60 on the frame 10.

[0098] like Figure 17 As shown, the floating mounting base 651 is disposed between the upper mounting plate 654 and the lower mounting plate 655, and is slidably connected to the connecting guide post 656. Correspondingly, the elastic element 653 is fitted onto the connecting guide post 656, and the end of the elastic element 653 away from the floating mounting base 651 abuts against the upper mounting plate 654. That is to say, the floating mounting base 651 can adjust the lifting and lowering of the elastic element 653 by compressing it between the upper mounting plate 654 and the lower mounting plate 655. During this process, the connecting guide post 656 guides the lifting and lowering movement of the floating mounting base 651. Here, the number of connecting guide posts 656 is configured to be multiple, and the multiple connecting guide posts 656 are arranged sequentially at intervals along the axial direction of the swing shaft 63. Among them, some connecting guide posts 656 are fitted with graphite copper sleeves 657, and these connecting guide posts 656 can be slidably connected to the floating mounting base 651 through the graphite copper sleeves 657. The remaining connecting guide posts 656 are fitted with elastic elements 653.

[0099] In summary, when the car transporter 100 of this application retrieves a car, the control module 50 on the car transporter 100 controls the two drive wheel mechanisms 20 to start according to the received external signals, so that the car transporter 100 can move on the walking surface and enter the bottom of the car 200 through the two drive wheel mechanisms 20 and the auxiliary support wheel mechanism 60. During this process, the wheelbase adjustment mechanism 40 can automatically adjust the distance between the two clamping arm mechanisms 30 according to the wheelbase of the car 200 to be transported. After the car transporter 100 is in place, the robotic arm 31 on the two clamping arm mechanisms 30 rotates out from the frame 10 and clamps the car tires to drive the car to lift off the walking surface. Then, the car transporter 100 can drive the car to move and complete the car retrieval action.

[0100] In addition, this application also provides a multi-level parking garage, including the car transporter 100 described above.

[0101] The technical features of the above embodiments can be combined in any way.
