[0002] With the continuous improvement of people's living standards, more and more people are buying private cars, which has a significant impact on urban traffic and the environment. The emergence of parking difficulties has also led to significant advancements in parking equipment technology. Parking equipment refers to mechanical or mechanical equipment systems used to store and retrieve vehicles in large quantities. AGV (Automated Guided Vehicle) automated driving and transport technology is also being applied in parking equipment. Existing gripping AGV vehicle transport robots can move freely within intelligent parking garages to transport vehicles. These robots consist of two bodies, front and rear, each equipped with two sets of symmetrically arranged gripping mechanisms. The front and rear bodies are positioned relative to each other via a detection mechanism during transport. However, during transport, the synchronization between the two bodies is poor, and the front and rear bodies may shift, obstructing lanes within the parking garage.

[0003] The existing method places two holding mechanisms on the same vehicle body, but the distance between the two holding structures is not adjustable, resulting in poor applicability.

[0004] Therefore, there is a need to provide a vehicle transporter to at least partially solve the above problems. Utility Model Content

[0101] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0102] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0103] Reference Figures 1 to 11 This utility model provides a vehicle transporter, including a vehicle body 100 and clamping components 400. The clamping components 400 are used to lift the wheels of the vehicle. Two sets of clamping components 400 are used to lift the front and rear wheels of the vehicle, respectively.

[0104] Reference Figure 5 In this design, the vehicle body 100 can be either a single integrated unit or a relatively fixed set of separate components. A single integrated unit provides greater structural stability. A separate unit allows for disassembly and reassembly as needed. Understandably, regardless of whether it's a single integrated unit or separate components, the overall length of the vehicle body 100 remains constant. This consistency in length helps ensure the transporter maintains stable posture and performance when handling vehicles. Regardless of vehicle size, the transporter maintains stable posture and performance, ensuring the safety and efficiency of the handling process. In this design, the length of the vehicle body 100 is greater than the vehicle's wheelbase; therefore, the spacing between the two sets of clamping components 400 can be adapted to the vehicle's wheelbase.

[0105] In some embodiments of this invention, the vehicle body 100 includes a slide rail 110 extending along the length direction DL of the vehicle body 100. The slide rail 110 enables the clamping assembly 400 to quickly and accurately position itself at the appropriate location on the vehicle, ensuring the vehicle transporter maintains a stable posture when handling vehicles of different sizes, avoiding swaying or tilting due to vehicle size mismatch, and improving transport efficiency. The slide rail 110 enhances the adaptability and flexibility of the vehicle transporter, enabling it to handle vehicles of different sizes.

[0106] Although this vehicle transporter with slide rail 110 and movable mounting part solves the problems of traditional transport methods to some extent, when the clamping component 400 slides to the slide rail 110, its connection strength with the vehicle body 100 is insufficient, causing the clamping component 400 to shake or tilt during transport, which affects the stability and safety of the transporter. It is easy for it to accidentally fall off or slide, posing a great safety hazard to the operator and the surrounding environment.

[0107] In this design, two sets of clamping assemblies 400 are configured. The two sets of clamping assemblies 400 are respectively installed to the first mounting part 210 and the second mounting part 220.

[0108] The first mounting part 210 is fixedly mounted to the vehicle body 100. Optionally, the first mounting part 210 is integrally formed with the vehicle body 100. When the clamping assembly 400 is mounted to the first mounting part 210, the relative position of the clamping assembly 400 and the vehicle body 100 remains unchanged along the length direction DL of the vehicle body 100.

[0109] The second mounting part 220 is movably mounted to the slide rail 110 along the length direction DL. When the clamping assembly 400 is mounted to the second mounting part 220, the clamping assembly 400 can move along the length direction DL of the vehicle body 100, thereby changing the relative distance between the two sets of clamping assemblies 400. The relative distance between the two sets of clamping assemblies 400 can be adjusted according to the size of the vehicle.

[0110] Reference Figure 7 In this design, the second mounting part 220 also includes a side-sliding pulley 221 located on the side of the slide rail 110. The second mounting part 220 is slidably connected to the slide rail 110 via the side-sliding pulley.

[0111] When the clamping assembly 400 is slidably connected to the slide rail 110, the connection between the slide rail 110 and the second mounting part 220 alone may result in insufficient connection strength, which may cause shaking or tilting during transportation.

[0112] A limiting guide rail 120 is provided on the side of the slide rail 110, and the limiting guide rail 120 extends in the same direction as the slide rail 110. The limiting guide rail 120 and the slide rail 110 together limit the movement track of the lateral pulley, so as to prevent the lateral pulley from tilting or deviating from the predetermined track during movement.

[0113] The limiting guide rail 120 is located above the side sliding wheel 221, and at least part of the projection of the limiting guide rail 120 along the height direction DH of the vehicle body 100 coincides with the projection of the side sliding wheel 221. The arrangement of the side sliding wheel 221 and the limiting guide rail 120 provides additional support and guidance, enhancing the connection strength between the second mounting part 220 and the vehicle body 100, thereby preventing the transporter from accidentally falling off during use. At the same time, the cooperative arrangement of the side sliding wheel 221, the slide rail 110, and the limiting guide rail 120 reduces wear and damage to the second mounting part 220 during movement.

[0114] In some embodiments of this utility model, the number of slide rails 110 is one or more. When the number of slide rails 110 is multiple, the multiple slide rails 110 are arranged at intervals along the width direction DW of the vehicle body 100.

[0115] In some embodiments of this invention, the side-sliding wheels 221 are arranged in two sets along the width direction DW of the vehicle body 100. The two sets of side-sliding wheels 221 are located on the outer side of the slide rail 110, which can form a more stable support structure.

[0116] In some embodiments of this utility model, the second mounting portion 220 further includes an upper sliding wheel 222 located above the slide rail 110. The upper sliding wheel 222 enhances the cooperation between the second mounting portion 220 and the slide rail 110, thereby further reducing wear and damage to the second mounting portion 220 during movement.

[0117] Based on the above embodiment, the number of slide rails 110 is one, with two sets of side sliding wheels 221 located on both sides of the slide rail 110, and two limiting guide rails 120 located on both sides of the slide rail 110. When the number of slide rails 110 is multiple, the two sets of side sliding wheels 221 are located outside the outermost slide rail 110, and the two limiting guide rails 120 are located outside the outermost slide rail 110. It can be understood that the two sets of side sliding wheels 221 are symmetrically arranged. The two limiting guide rails 120 are symmetrically arranged. Optionally, after the second mounting part 220 is installed onto the slide rail 110, the limiting guide rails 120 are fastened to the slide rail 110 by fasteners.

[0118] The above solution ensures that the second mounting part 220 is subjected to symmetrical and balanced forces, which helps to prevent it from shaking, tilting or falling off during movement and use, thereby enhancing the safety of the transporter.

[0119] In some embodiments of this utility model, the second mounting part 220 is provided with a linear drive module 300, which is used to drive the second mounting part 220 to move along the slide rail 110.

[0120] Optionally, the second mounting section 220 is provided with a battery compartment 223 for placing batteries, located between adjacent slide rails 110. The battery compartment 223 is used to supply power to the linear drive module 300. Optionally, the battery compartment 223 is an upward-opening and downward-recessed compartment, facilitating the installation and maintenance of the battery pack. The opening of the battery compartment 223 is provided with a cover 224 that can close the battery compartment 223 to prevent dirt from entering the battery compartment 223 and affecting the normal operation of the battery pack.

[0121] Optionally, the specific types of the linear drive module 300 include, but are not limited to, screw drive mechanisms, rack and pinion mechanisms, linear motor mechanisms, and pneumatic / hydraulic linear modules.

[0122] Reference Figures 8 to 9 The following explanation will focus on the linear drive module 300 as a lead screw transmission mechanism.

[0123] The linear drive module 300 includes a lead screw 310, a first drive component 320, a connector 330, and a support assembly.

[0124] The lead screw 310 is rotatably connected to the vehicle body 100. The lead screw 310 is supported and fixed to the vehicle body 100 by bearings or similar devices to ensure stable rotation. The surface of the lead screw 310 is threaded. Optionally, the lead screw 310 can be a single, continuous screw or a partial screw.

[0125] The lead screw 310 extends in the same direction as the slide rail 110. In some embodiments, multiple slide rails 110 are provided, and the lead screw 310 is located between adjacent slide rails 110. This layout can effectively utilize space and reduce the size of the vehicle transporter.

[0126] The first driving member 320 is used to drive the lead screw 310 to rotate. Optionally, the type of the first driving member 320 includes, but is not limited to, a stepper motor or a servo motor. The first driving member 320 is connected to the lead screw 310 and converts electrical energy into mechanical energy. Optionally, a transmission pair is also provided between the first driving member 320 and the lead screw 310. The type of transmission pair includes, but is not limited to, gear transmission pairs, belt transmission pairs, and chain transmission pairs. For example, the transmission pair is a gear transmission pair to transmit power. Specifically, the output end of the first driving member 320 is connected to a first gear 371, and the end of the lead screw 310 is connected to a second gear 372. The first gear 371 and the second gear 372 mesh. That is, driven by the first driving member 320, the first gear 371 and the second gear 372 transmit power, thereby driving the lead screw 310 to rotate, and finally driving the second mounting part 220 to slide linearly along the slide rail 110.

[0127] The connector 330 is threadedly connected to the lead screw 310. The connector 330 is fitted onto the outer circumference of the lead screw 310. The connector 330 has a threaded structure that matches the thread of the lead screw 310. When the lead screw 310 rotates, the connector 330 will move linearly along the length direction DL of the lead screw 310. Optionally, the connector 330 is a nut.

[0128] The support assembly is used to mount the second mounting part 220. The support assembly includes at least two supports 340, which are movable along the length direction DL of the lead screw 310. One of the supports 340 is connected to the connector 330 and moves with the connector 330. Both supports 340 are fixed relative to the second mounting part 220 to provide stable support. Both supports 340 are sleeved onto the outer periphery of the lead screw 310. The two supports 340 are respectively connected to the front end and the rear end of the second mounting part 220. The connector 330 can be mounted to either the front support 340 or the rear support 340, which is not specifically limited in this embodiment.

[0129] The linear drive module 300 provided by this solution has the technical advantages of high-precision positioning, high load capacity, stability and reliability, and easy control.

[0130] In some embodiments of this utility model, the connector 330 is connected to the support 340 via a fastener 350, and an elastic element 360 is provided between the connector 330 and the support 340. The type of fastener 350 includes, but is not limited to, bolts and pins. Optionally, the elastic element 360 is fitted onto the outer periphery of the fastener 350. In this solution, the connector 330, as an important transmission component, drives the second mounting part 220 to move as a whole. Through the buffering and shock absorption effect of the elastic element 360, the distance between the connector 330 and the support 340 can be finely adjusted.

[0131] Reference Figure 4 The following describes the specific clamping component 400.

[0132] The clamping assembly 400 includes two pairs of clamping arms 410, which are spaced apart and symmetrically arranged along the width direction DW of the vehicle body 100. Each pair of clamping arms 410 consists of two arms, forming a clamping space for holding the vehicle wheels. By optimizing the arrangement of the clamping assembly 400, wheels can be clamped and released, thereby shortening the overall handling time and improving handling efficiency.

[0133] The clamping arm 410 includes a hinged end and a free end arranged opposite to each other. The hinged end is hinged to either the first mounting part 210 or the second mounting part 220. A gear 411 is provided at the hinged end of the clamping arm 410, and the rotation center of the gear 411 coincides with the rotation center of the clamping arm 410. Through the setting of the gear 411, precise control and coordinated movement of the clamping arm 410 can be achieved.

[0134] The two clamping arms 410 in each pair rotate in opposite directions. That is, the two clamping arms 410 can be relatively close, that is, the two clamping arms 410 simultaneously move towards the center to clamp the wheel; the two clamping arms 410 can be relatively far apart, that is, the two clamping arms 410 simultaneously move towards the vehicle body 100 to release the wheel. When the two clamping arms 410 are in the clamping state, the free ends of the clamping arms 410 are suspended in the air.

[0135] The clamping assembly 400 also includes a second drive 420 for driving the two clamping arms 410 of each pair to rotate synchronously.

[0136] Optionally, the two clamping arms 410 in each pair are connected to the transmission member 430 via their respective gears 411, and the transmission member 430 is driven by the second driving member 420. That is, the transmission member 430 is engaged with the gears 411 of the two clamping arms 410 in each pair.

[0137] Optionally, the two clamping arms 410 in each pair are connected to each other by meshing gears 411, and the second drive member 420 is connected to one of the clamping arms 410 or gears 411 by a transmission member 430.

[0138] The two transmission methods described above, through the meshing of gears 411, ensure the synchronicity and stability of the two clamping arms 410 during rotation. Precise control of the second drive component 420 controls the synchronous movement of the clamping arms 410 to achieve a stable clamping effect.

[0139] Based on the above embodiments, the second drive component 420 is one of a worm gear mechanism, a linear motor mechanism, or a pneumatic / hydraulic linear module.

[0140] For example, the second driving component 420 is a worm gear mechanism. The second driving component 420 is a motor, and the transmission component 430 is a worm. The worm is connected to the output end of the motor. The worm gear is connected to the hinge end of the clamping arm 410; optionally, the worm gear and the hinge end of the clamping arm 410 are coaxially arranged. The worm and worm gear mesh, that is, the motor drives the worm gear to rotate, the worm gear rotation drives the worm gear to rotate, thereby causing the clamping arm 410 to rotate around the hinge axis, realizing the relative approach or distance of the clamping arms 410. Optionally, each pair of clamping arms 410 corresponds to one worm gear, and the two worm gears rotate in opposite directions. The two worm gears mesh with the same worm gear, realizing that one set of motors simultaneously drives two sets of worm gears to rotate, thereby driving the two clamping arms 410 to rotate synchronously in opposite directions, realizing the opening or closing of the clamping arm 410 mechanism. The worm gear mechanism has a self-locking function, which can prevent the clamping arms 410 from not closing automatically without external force when open, ensuring the safety of the vehicle transporter.

[0141] For example, the second driving component 420 is a hydraulic linear module. The second driving component 420 is a hydraulic cylinder, and the transmission component 430 is a connecting rod. The connecting rod is hinged to the output end of the hydraulic cylinder and one of the clamping arms 410 or gears 411. In this solution, the connecting rod is hinged to the output end of the hydraulic cylinder and one of the clamping arms 410. Specifically, the end of the clamping arm 410 near the hinge end is connected to the transmission rod. The hydraulic cylinder is connected to the middle of the transmission rod. The hydraulic cylinder drives the transmission rod to rotate, thereby causing one clamping arm 410 to rotate around the hinge end of the clamping arm 410. The two clamping arms 410 are driven by the meshing of gears 411, thereby realizing the opening or closing of the clamping arms 410. In this solution, the gears 411 and the hinge ends of the clamping arms 410 are coaxially arranged, and the transmission ratio of the meshing gears 411 is 1.

[0142] In some embodiments of this utility model, a plurality of rotating bodies 440 are provided between the hinged end and the free end of the clamping arm 410. The plurality of rotating bodies 440 are coaxially arranged. During clamping, the rotating bodies 440 contact the vehicle tire to reduce the friction between the tire and the clamping arm 410 and avoid damage to the tire. The types of rotating bodies 440 include, but are not limited to, long rollers and bearings.

[0143] In some embodiments of this utility model, the free end of the clamping arm 410 is provided with a support wheel 450, and the rotation axis of the rotating body 440 is coaxial with the rotation axis of the support wheel 450.

[0144] Based on the above embodiment, a storage groove 141 is provided on the side of the vehicle body 100, and the clamping assembly 400 can be stored in the storage groove 141. When the clamping assembly 400 is stored in the storage groove 141, the support wheel 450 is supported within the storage groove 141. Optionally, the side frame 140 of the vehicle body 100 can be directly made of profiles such as channel steel, and the slots in the channel steel form the storage groove 141. This groove is used to store the clamping arm 410 when it is retracted.

[0145] Based on the above embodiment, the diameter of the support wheel 450 is larger than the diameter of the rotating body 440. When the clamping arm 410 is stored in the storage groove 141, the support wheel 450 can slide into the storage groove 141 and be supported in the storage groove 141.

[0146] Based on the above embodiments, the second driving component 420 employs a hydraulic cylinder. The vehicle transporter also includes a hydraulic drive assembly 600. That is, the clamping assembly 400 is driven by the hydraulic drive assembly 600. As mentioned above, the two sets of clamping assemblies 400 are used to lift the front and rear wheels of the vehicle, respectively. In this solution, two hydraulic drive assemblies 600 are respectively configured to correspond to the two sets of clamping assemblies 400. That is, one hydraulic drive assembly 600 drives one set of clamping assemblies 400 to lift the front wheels of the vehicle, and the other hydraulic drive assembly 600 drives the other set of clamping assemblies 400 to lift the rear wheels of the vehicle. By equipping each set of clamping assemblies 400 with an independent hydraulic drive assembly 600, the clamping force and action mode of each set of clamping assemblies 400 can be controlled more precisely to adapt to the different force conditions of the front and rear wheels. Optionally, the front and rear wheels can be lifted simultaneously or at different times. The vehicle transporter of this solution can provide different timing rhythms or intensities during the lifting process. For example, during the lifting process, it may be necessary to stabilize the front wheels first and then the rear wheels, or the lifting sequence of the clamping components 400 may be adjusted according to the vehicle's center of gravity. Optionally, the hydraulic drive components 600 are located at the front and rear ends of the vehicle body 100, respectively. The clamping component 400 connected to the first mounting part 210 is driven by the front hydraulic drive component 600, and the clamping component 400 connected to the second mounting part 220 is driven by the rear hydraulic drive component 600.

[0147] In some embodiments of this invention, the vehicle transporter further includes a lifting device 500, which drives the clamping assembly 400 to move along the height direction DH of the vehicle. The lifting device 500 is driven by a hydraulic drive assembly 600.

[0148] In this solution, the hydraulic cylinder serves as the main power source, generating thrust through the flow of hydraulic oil, thereby driving the movement of the clamping assembly 400 and the lifting device 500, thus further adapting to different vehicle models.

[0149] In some embodiments of this invention, two sets of lifting devices 500 are spaced apart along the width direction DW of the vehicle body 100, thereby maintaining overall stability and balance when lifting the vehicle. This arrangement ensures that the vehicle will not tilt or tip over due to a shift in the center of gravity during lifting, improving the safety of the handling process. Optionally, each set of lifting devices 500 may consist of one or more, and the same set of lifting devices 500 is driven by the same hydraulic drive assembly 600. For example, the left-side lifting device 500 is driven by the front hydraulic drive assembly 600, and the right-side lifting device 500 is driven by the rear hydraulic drive assembly 600. Optionally, the lifting cylinder is preferably a two-stage single-acting cylinder, achieving a high lifting height with a relatively small installation height, reaching a maximum lifting height of approximately 90mm.

[0150] Reference Figures 5 to 6 Based on the above embodiments, the vehicle body 100 includes a chassis 130 and a frame 140, with a lifting device 500 installed between the chassis 130 and the frame 140. Specifically, the cylinder body of the lifting cylinder is fixedly connected to the top of the chassis 130, and the frame 140 is fixedly connected to the piston rod of the lifting cylinder. A clamping assembly 400 is installed to the frame 140. Each group of lifting devices 500 has at least three units, with at least one traveling device 700 located at the front end of the vehicle body 100, at least one traveling device 700 located at the rear end of the vehicle body 100, and at least one traveling device 700 located in the middle of the vehicle body 100. This distribution helps maintain the stability and balance of the vehicle body 100 during movement. In this solution, the lifting devices 500 are arranged at the load-bearing concentration points of the vehicle body 100, i.e., near the chassis 130 of the first mounting portion 210 or the second mounting portion 220, reducing the risk of structural damage due to uneven stress distribution.

[0151] The vehicle body 100, through the lifting device 500, allows the frame 140 to be movably supported on the chassis 130. Optionally, the chassis 130 adopts an integral welded structure. The frame 140 also adopts an integral welded structure, which can be raised and lowered along the height direction DH. The clamping assembly 400 is connected to the frame 140, allowing the clamping assembly 400 to rise and fall with the frame 140, thereby raising the entire vehicle to a certain height and ensuring that the vehicle tires are at a certain height from the ground, enabling the thin vehicle handling robot to adapt to different garage site requirements.

[0152] In some embodiments, along the length direction DL, a first mounting portion 210 is disposed at the front end of the frame 140, and a second mounting portion 220 is disposed at the rear end of the frame 140. Optionally, a downwardly recessed accommodating space 230 is formed between the first mounting portion 210 and the second mounting portion 220 for mounting and arranging components such as electrical components, hydraulic components, circuits, or oil circuits. Optionally, a first driving member 320 is located within the accommodating space 230.

[0153] Optionally, a detachable cover 150 is connected to the top of the vehicle body 100. The cover 150 is bolted to the vehicle body 100 to enclose the first mounting portion 210, the second mounting portion 220, the clamping assembly 400, and the accommodating space 230, preventing dust from entering. Optionally, the cover 150 is fixedly mounted above the frame 140 and can rise and fall with the frame 140.

[0154] For example, there are eight lifting devices 500. Four of the lifting devices 500 are arranged diagonally and are located on the chassis 130 near the four corners of the first mounting portion 210. The other four lifting devices 500 are also arranged diagonally and are located on the chassis 130 near the four corners of the second mounting portion 220. Since the second mounting portion 220 can move relative to the chassis 130 along the slide rail 110, the four lifting devices 500 are specifically positioned on the chassis 130 near the four corners of the slide rail 110. The lifting devices 500 provide more stable support for the frame 140.

[0155] Both the clamping assembly 400 and the lifting device 500 are powered by the hydraulic drive assembly 600.

[0156] Reference Figures 10 to 11 The hydraulic drive assembly 600 includes an oil tank 610 and a hydraulic pump 620. The oil tank 610 and the hydraulic pump 620 are connected by a pipeline 650. The pipeline 650 is responsible for delivering hydraulic oil from the oil tank 610 to the hydraulic cylinder to generate the required driving force. Two pipelines 650 are provided at the outlet of the hydraulic pump 620: one supplies oil to the hydraulic cylinder of the clamping assembly 400, and the other supplies oil to the hydraulic cylinder of the lifting device 500. The hydraulic cylinders of the clamping assembly 400 and the lifting device 500 achieve telescopic movement according to the flow and pressure changes of the hydraulic oil.

[0157] Based on the above embodiment, the pipeline 650 is equipped with a control valve 630. The control valve 630 regulates the flow rate and pressure of the hydraulic oil. The type of control valve 630 includes, but is not limited to, solenoid valves, throttle valves, and directional valves. Two control valves 630 are respectively provided corresponding to two sets of clamping assemblies 400. Optionally, the hydraulic cylinders of the two pairs of clamping arms 410 of the same set of clamping assemblies 400 are controlled by the same control valve 630 to ensure the synchronization of the same set of clamping assemblies 400.

[0158] Based on the above embodiment, the pipeline 650 is provided with a balance valve 640. Optionally, the balance valve 640 is located between the control valve 630 and the hydraulic cylinders of the same set of clamping assemblies 400. The control valve 630 ensures that the oil flow distribution of the hydraulic cylinders of the same set of clamping assemblies 400 is uniform, thereby balancing the driving force of the two pairs of clamping arms 410 and making the clamping force of the two pairs of clamping arms 410 the same.

[0159] The vehicle transporter also includes multiple traveling devices 700, which are fixedly mounted to the vehicle body 100 and are used to drive the vehicle body 100 in all directions. Specifically, the traveling devices 700 are connected to the lower end of the chassis 130.

[0160] The aforementioned walking device 700 may consist of only a drive wheel mechanism, or it may employ a structure that combines a drive wheel mechanism with a swivel wheel mechanism. The drive wheel mechanism may be at least one of a differential wheel mechanism, a steering wheel mechanism, or a Mecanum wheel mechanism.

[0161] The following explanation uses the differential gear mechanism as an example.

[0162] The walking device 700 includes two walking wheels 710, each of which can be driven independently, and the rotation axes of the two walking wheels 710 are parallel or coincident. During movement, the vehicle body 100 can be balanced, steered, or driven by independently controlling each walking wheel 710. For example, controlling the two walking wheels 710 to use different speeds can cause the vehicle body 100 to steer in a balanced manner, enabling the vehicle body 100 to avoid obstacles, enter parking spaces, or meet the needs of other driving paths.

[0163] Based on the above embodiment, the traveling wheel 710 is driven to rotate by the third drive member 720. Optionally, the third drive member 720 is a geared motor. The traveling wheel 710 is connected to the output end of the geared motor.

[0164] At least two sets of traveling devices 700 are spaced DW apart along the width direction of the vehicle body 100 to ensure the lateral stability of the vehicle body 100 and prevent the vehicle body 100 from overturning or tilting during operation. Each set of traveling devices 700 contains at least three units, with at least one traveling device 700 located at the end of the first mounting portion 210 away from the second mounting portion 220, and at least one traveling device 700 located at the end of the second mounting portion 220 away from the first mounting portion 210. That is, traveling devices 700 are provided at both the front and rear ends of the vehicle body 100, making the vehicle body 100 more flexible and stable when turning or adjusting its direction. Precise control of the vehicle body 100 can be achieved by adjusting the speed and direction of the traveling devices 700 at different positions. At least one traveling device 700 is located at the end of the first mounting portion 210 near the second mounting portion 220, while the traveling device 700 in the middle position connects and supports the two sets of traveling devices 700, enhancing the overall structural strength of the vehicle body 100. By setting up multiple walking devices 700, the weight of the vehicle body 100 is effectively distributed, the load-bearing capacity is enhanced, and the vehicle body 100 can bear a greater load. By controlling the walking devices 700 separately, the vehicle body 100 can be precisely controlled and flexibly turned, thus improving the adaptability and passability of the vehicle body 100.

[0165] In some embodiments of this utility model, both the first mounting portion 210 and the second mounting portion 220 are provided with a detection mechanism. The detection mechanism is used to detect vehicle tires. For example, when the detection mechanism of the first mounting portion 210 detects the front tire of the vehicle, it sends a signal, and the vehicle transporter stops moving forward; at this time, the second mounting portion 220 slides along the slide rail 110 of the vehicle body 100. When the detection mechanism on the second mounting portion 220 detects the rear tire of the vehicle, it sends a signal, and the second mounting portion 220 stops sliding. This detection mechanism can be a proximity switch.
