Description

Technical Field

[0001] The present invention relates to the field of automated equipment for stereo garages, and in particular to a heavy-load vehicle transporter and method. Background Art

[0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art.

[0003] In the automatic parking system, a vehicle carrier that can move independently is required to carry the vehicle so as to carry the vehicle to a preset parking space.

[0004] The existing vehicle transporter includes a main structure, a holding arm and running wheels. The holding arm is rotatably connected to the main structure, and the running wheels are distributed at the end positions of the main structure and are rotatably connected to the main structure. The vehicle transporter transports the vehicle by holding the front and rear wheels of the vehicle with the holding arms. During the transport process, the gravity of the vehicle is transmitted to the main structure through the holding arms, and then transmitted to the running wheels through the main structure. In order to adapt to vehicles with different wheelbases, the length of the holding vehicle transporter is usually large, and thus the length of the main structure is long, which causes the main structure of the vehicle transporter to deform more under heavy load, seriously affecting the carrying capacity of the vehicle transporter.

[0045] The following specific implementations will further illustrate the present disclosure in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0046] In order to more clearly understand the above-mentioned purposes, features and advantages of the present disclosure, the present disclosure is described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. In the following description, many specific details are set forth in order to fully understand the present disclosure, and the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used in the specification herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0048] In each embodiment, for the convenience of description and not to limit the present disclosure, the term "connection" used in the patent specification and claims of the present disclosure is not limited to physical or mechanical connection, whether direct or indirect. "Up", "down", "below", "left", "right", etc. are only used to indicate relative position relationship. When the absolute position of the described object changes, the relative position relationship also changes accordingly.

[0049] The existing vehicle transporter directly connects the walking mechanism (walking wheels, walking motors and other components) and the holding mechanism (holding arms, holding motors and other components) to the main frame structure of the vehicle transporter, which has the advantages of simple structure and easy installation. However, since the vehicle transporter needs to adapt to the length of the vehicle, the main frame structure of the vehicle transporter is relatively long, which inevitably causes deformation of the main frame during the process of transporting the vehicle, especially in harsh working environments (uneven ground, vibrations and other factors). The deformation of the main frame seriously affects the service life and carrying capacity of the vehicle transporter. To this end, the present invention combines the walking mechanism and the holding device so that the walking mechanism directly carries the wheels of the vehicle through the holding device, thereby effectively improving the problem of deformation of the main structure.

[0050] Figure 1 This is a schematic diagram of the structure of the heavy-duty vehicle carrier with its holding arm retracted. Figure 2 This is a schematic diagram of the structure of the heavy-duty vehicle carrier with its holding arm open. Figure 3 This is a top view of the heavy-duty vehicle carrier with its arms open. Figure 1 , Figure 2 and Figure 3As shown, the heavy-load vehicle transporter is used to transport vehicles, especially to transport vehicles in a stereo garage or an intelligent garage, to achieve the transfer of vehicles. The heavy-load vehicle transporter includes a first transport mechanism 10 and a second transport mechanism 20. Among them, the first transport mechanism 10 is used to carry the front wheels of the vehicle, and the second transport mechanism 20 is used to carry the rear wheels of the vehicle. Those skilled in the art understand that the first transport mechanism 10 can also be used to carry the rear wheels of the vehicle, and the second transport mechanism 20 is used to carry the front wheels of the vehicle. The present disclosure does not limit this. As an example, the following description is based on the first transport mechanism 10 being used to carry the front wheels of the vehicle, and the second transport mechanism 20 being used to carry the rear wheels of the vehicle. The first transport mechanism 10 and the second transport mechanism 20 cooperate to move the vehicle.

[0051] The first transport mechanism 10 includes a first main body 11 and a first support portion 12. The first main body 11 is a generally rectangular frame structure, and the end portion can also be rotatably connected to support wheels 50 to assist walking. In this embodiment, the number of support wheels 50 is four pairs, which are respectively located at both ends and the middle position of the vehicle transporter, and two pairs of support wheels 50 are located on both sides of the connection position of the first transport mechanism 10 and the second transport mechanism 20 at the middle position.

[0052] The first transport mechanism 10 and the second transport mechanism 20 are hinged by the second pin shaft 40, and the axial direction of the second pin shaft 40 is along the width direction of the heavy-load vehicle transporter, so that when the heavy-load vehicle transporter carries a vehicle and walks on an uneven ground, the first transport mechanism 10 and the second transport mechanism 20 arranged in the front and rear are slightly adjusted so that the support wheels 50 at both ends can touch the ground and the support wheels 50 will not be suspended in the air.

[0053] Figure 4 is a schematic structural diagram of the first supporting part, Figure 5 is a schematic diagram of the structure of the first support portion from another perspective. Figure 4 , Figure 5 As shown, the first support portion 12 includes a first base 121, a first holding mechanism 122 and a first walking mechanism 123. The first base 121 is generally a flat plate structure, which can be fixedly connected to the first body 11 by means of connectors, riveting, welding, etc. as shown in the figure, but can also be movably connected by means of sliders 2211, rails 211, ball screws, etc.

[0054] The first holding mechanism 122 is used to hold the wheels of the vehicle. The first holding mechanism 122 includes a holding motor 1221, a first transmission gear 1222, a transmission rod 1223 and a holding arm 1225. In this embodiment, the first holding mechanism 122 includes two pairs of holding arms 1225, which are used to hold the two front wheels respectively, and each pair of holding arms 1225 can be opened or retracted at the same time to assist each other in holding the wheels. The ends of the holding arms 1225 are hinged to the bottom surface of the first base 121 (i.e., the side facing the first walking mechanism 123), and a pair of holding arms 1225 are provided on one side of the first base 121, and the other pair of holding arms 1225 are rotatably connected to the other side of the first base 121. The holding arm 1225 is provided with a plurality of rollers 1225a along the length direction. When the holding arm 1225 is opened or retracted, the rollers 1225a roll in contact with the tire of the vehicle, which can reduce the friction between the tire and the wheel when holding or releasing the wheel, and reduce the wear on the tire. A worm wheel 1224 is provided at the end of the holding arm 1225. The gear teeth of the worm wheel 1224 extend and distribute along the circumferential direction of the worm wheel 1224. The number of gear teeth can be set according to the rotation angle of the holding arm 1225. The transmission rod 1223 is rotatably connected to the first base body 121 through a bearing. The two ends of the transmission rod 1223 are respectively connected to a worm 1223a meshed with the worm wheel 1224 of the holding arm 1225. In addition, one end of the transmission rod 1223 is coaxially connected to an output gear, and the output gear meshes with the output gear of the holding motor 1221. When the holding motor 1221 rotates, the transmission rod 1223 can be driven to rotate through the output gear, and the worm 1223a at both ends of the transmission rod 1223 drives a pair of holding arms 1225 to open or retract synchronously through the worm gear 1224.

[0055] The first walking mechanism 123 is connected to the first base body 121 and is located below the first holding mechanism 122 for realizing a walking function.

[0056] Figure 6 is an exploded view of the first support. Figure 5 and Figure 6 As shown, the first walking mechanism 123 includes a walking frame 1231, a bearing 1235, a connecting frame 1233, a pair of walking motors 1236, a pair of walking wheels 1232 and four elastic members 1237. Figure 6As shown, the connecting frame 1233 is generally a tripod structure, with a flat plate structure at the top, and the top of the connecting frame 1233 is connected to the bearing 1235. The bearing 1235 is preferably a cross roller bearing, which is a special bearing with a split inner ring and a rotating outer ring. Because the inner ring or outer ring of the cross roller bearing is a two-split structure, the bearing gap can be adjusted, and even if a preload is applied, high-precision rotation can be obtained. The cross roller bearing is connected between the first base 121 and the connecting frame 1233, so that the connecting frame 1233 can rotate around the central axis in the vertical direction.

[0057] The walking frame 1231 is a generally rectangular three-dimensional frame structure, and a mounting hole is provided in the middle of the inner side. The bottom of the connecting frame 1233 passes through the mounting hole through the first pin 1234 to connect the walking frame 1231. Preferably, the axial direction of the first pin 1234 extends in the horizontal direction and along the walking direction (front and rear direction) of the vehicle carrier, so that the walking frame 1231 can swing in the vertical plane relative to the connecting frame 1233. In addition, four elastic members 1237 are respectively connected to the walking frame 1231 and the connecting frame 1233. When the walking frame 1231 swings relative to the connecting frame 1233, the elastic members 1237 are used for buffering, making the swing more stable and avoiding impact. Preferably, the elastic member 1237 is a compression spring. During the walking process, the vibration and deformation of the heavy-loaded vehicle carrier caused by uneven ground during the walking process can be reduced by the relative swing of the walking frame 1231 relative to the connecting frame 1233. In this embodiment, there are two walking motors 1236, which are respectively connected to the walking frame 1231. There is a pair of walking wheels 1232, which are respectively rotatably connected to the two sides of the walking frame 1231 and are respectively connected to a walking motor 1236, so that the walking motor 1236 can drive the walking wheels 1232 to rotate. Since each walking wheel 1232 is correspondingly connected to a walking motor 1236, by controlling the output speed of the walking motor 1236, the synchronous rotation of the pair of walking wheels 1232 can be achieved to achieve forward or backward walking; the pair of walking wheels 1232 can also be controlled to rotate differentially to achieve a steering function.

[0058] The second transport mechanism 20 includes a second body 21, a second support portion 22, a second walking mechanism 23 and a moving device 24. The second body 21 is similar to the first body 11, and is a generally rectangular frame structure, and can also be rotatably connected to the support wheel 50 at the end to assist walking. The second body 21 is hinged to the end of the first body 11 through the second pin 40, so that the first body 11 and the second body 21 can rotate relative to each other. When the vehicle transporter travels to an uneven area, the first transport mechanism 10 and the second transport mechanism 20 are rotated to fit the ground, so as to avoid any of the walking mechanisms of the vehicle transporter being suspended or deformed too much under the action of the vehicle's gravity. Preferably, the two pairs of support wheels 50 located in the middle are rotatably arranged on both sides of the hinge point of the first body 11 and the second body 21, so as to balance the forces on the first body 11 and the second body 21.

[0059] Figure 7 Schematic diagram of the structure of the second support part. Figure 7 As shown, the second supporting portion 22 includes a second base 221 and a second holding mechanism 222 .

[0060] The second holding mechanism 222 is used to hold the wheels of the vehicle. The second holding mechanism 222 includes a holding motor 1221, a second transmission gear 2221, a transmission rod 1223 and a holding arm 1225. In this embodiment, the second holding mechanism 222 includes two pairs of holding arms 1225, which are used to hold the two front wheels respectively. Each pair of holding arms 1225 can be opened or retracted at the same time to assist each other in holding the wheels. The ends of the holding arms 1225 are hinged to the bottom surface of the second base 221, and one pair of holding arms 1225 is arranged on one side of the second base 221, and the other pair of holding arms 1225 is rotatably connected to the other side of the second base 221. The holding arms 1225 are provided with a plurality of rollers 1225a along the length direction. When the holding arms 1225 are opened or retracted, the rollers 1225a roll in contact with the tires of the vehicle, which can reduce the friction between the tires when holding or releasing the wheels, and reduce the wear on the tires. A worm wheel 1224 is provided at the end of the holding arm 1225, and the gear teeth of the worm wheel 1224 extend and are distributed along the circumferential direction of the worm wheel 1224, and the number of gear teeth can be set according to the size of the rotation angle of the holding arm 1225. The transmission rod 1223 is rotatably connected to the second base body 221 via a bearing, and the two ends of the transmission rod 1223 are respectively connected to a worm 1223a that meshes with the worm wheel 1224 of the holding arm 1225. In addition, the transmission rod 1223 is coaxially connected to an output gear, and the output gear meshes with the output gear of the holding motor 1221. When the holding motor 1221 rotates, the transmission rod 1223 can be driven to rotate by the output gear, and the worms 1223a at both ends of the transmission rod 1223 drive a pair of holding arms 1225 to open or retract synchronously through the worm wheel 1224.

[0061] The second base 221 is movably connected to the second main body 21 through a slider 2211-slide rail 211 structure. Specifically, two sliders 2211 are connected to both sides of the side of the second base 221 facing the holding motor 1221, and the second main body 21 is connected to the slide rail 211 (such as Figure 2 As shown), the second base 221 is movably connected to the second body 21 through a slider 2211 and a slide rail 211.

[0062] The moving device 24 is connected to the second body 21 and the second support portion 22, and can drive the second support portion 22 to move relative to the second body 21 along the length direction of the heavy-duty vehicle carrier. Figure 3 As shown, the moving device 24 includes a moving motor 241, a first sprocket 242, a second sprocket 243 and a chain 244. The first sprocket 242 is connected to the moving motor 241 fixedly set on the second body 21, the second sprocket 243 is rotatably connected to the second body 21, and the second sprocket 243 is spaced apart from the first sprocket 242. The two ends of the chain 244 are connected to the second base 221 after bypassing the first sprocket 242 and the second sprocket 243 respectively. In this way, the chain 244 forms a ring chain structure through the second base 221, so that the moving motor 241 drives the chain 244 to rotate through the sprocket, and the two ends of the chain 244 drive the second base 221 to move.

[0063] The second walking mechanism 23 is connected to the outer end of the second body 21 to support the walking of the second body 21. The second walking mechanism 23 is the same as the first walking mechanism 123, and will not be described again.

[0064] When it is necessary to transport a vehicle, the heavy-load vehicle transporter can be moved to the bottom of the vehicle so that the position of the first support portion 12 corresponds to the front wheel of the vehicle, so that the first support portion 12 can hold the front wheel. Then, the moving device 24 drives the second support portion 22 to move to the position corresponding to the rear wheel of the vehicle, so that the second support portion 22 can hold the rear wheel, and the function of transporting the vehicle is realized through the cooperation between the first support portion 12 and the second support portion 22. In this way, the first walking mechanism 123 is located below the first support portion 12, and the vehicle tire is directly carried through the first base 121 and the first holding mechanism 122, which effectively reduces the overall length of the vehicle transporter and facilitates passage.

[0065] Also, please refer again to Figure 1 and Figure 2, the vehicle carrier also includes a navigation device 30, a power supply device 60 and a control system. In this embodiment, the navigation device 30 can be a laser scanner and / or a safety radar, which is arranged at the outer ends of the first body 11 and the second body 21. The control system can also be arranged in the first body 11 or the second body 21, and connected to the navigation device 30 to control the walking, holding and other related actions of the vehicle carrier. In some embodiments, a power supply device 60 can also be provided inside the first body 11, and the power supply device 60 includes a battery 61 and a charging device 62, so that there is no need to connect a power supply cable to achieve wireless operation. The charging device 62 is connected to the battery 61 for charging the battery 61. The charging device 62 can be fixedly arranged on the side wall of the first body 11 and / or the second body 21, can be arranged on the side wall of the outer end of the first body 11 and / or the second body 21, and can also be arranged on the left and right side walls of the first body 11 and / or the second body 21, for docking with the charging socket to charge the vehicle carrier.

[0066] In combination with the above-mentioned heavy-load vehicle transporter, a heavy-load vehicle transport method is described in detail below. The heavy-load vehicle transport method includes the following steps.

[0067] First, under the guidance of the navigation device 30, the control system controls the heavy-load vehicle transporter to move to the bottom of the vehicle to be transported, that is, the first transport mechanism 10 and the second transport mechanism 20 are located under the vehicle. At this time, the position of the first support portion 12 corresponds to the position of the front wheels of the vehicle.

[0068] Then, the control system controls the moving device 24 of the second transport mechanism 20 to move, so that the second base 221 of the second support part 22 moves along the slide rail 211 on the second body 21 until the position of the second support part 22 corresponds to the rear wheel position of the vehicle.

[0069] Next, the holding arms 1225 of the first support portion 12 and the second support portion 22 are opened, and the front wheels and rear wheels of the vehicle are clamped respectively with the assistance of the rollers 1225a of the holding arms 1225, until the holding arms 1225 hold the front wheels and rear wheels of the vehicle respectively. At this time, the running wheels 1232 of the first support portion 12 sequentially carry the front wheels of the vehicle through the running frame 1231, the first base body 121 and the holding arms 1225, and the running wheels 1232 of the second running mechanism 23 sequentially carry the rear wheels of the vehicle through the second body 21, the second base body 221 and the holding arms 1225 to carry the vehicle.

[0070] Then, the control system controls the travel motor 1236 to operate, and the first travel mechanism 123 and the second travel mechanism 23 operate synchronously to move the transport vehicle. During the movement, according to actual needs, the travel wheels 1232 can be controlled to rotate differentially to make the first support part 12 and the second support part 22 turn, and then the travel wheels 1232 rotate synchronously to make the heavy-load vehicle transporter move in the direction after turning until the vehicle is transported to the destination.

[0071] Finally, the control system controls the holding arms 1225 of the first support portion 12 and the second support portion 22 to be retracted, at which point the wheels of the vehicle touch the ground and the heavy-load vehicle carrier is located below the vehicle. Then, the heavy-load vehicle carrier can shuttle through the bottom of the vehicle to complete the vehicle handling process.

[0072] The walking wheels 1232 of the first supporting part 12 and the second supporting part 22 are a pair respectively, and the walking frames 1231 of the first supporting part 12 and the second supporting part 22 are turned by differential rotation;

[0073] The running wheels 1232 of the first supporting portion 12 and the second supporting portion 22 rotate synchronously to carry the vehicle to move in the direction after turning.

[0074] Beneficial effect: After the first holding mechanism 122 holds the wheel of the vehicle, the walking wheel 1232 of the first walking mechanism 123 bears the weight of the front wheel of the vehicle through the through-hole walking frame 1231, the first base body 121 and the first holding mechanism 122 in sequence. When transporting the vehicle, part of the gravity of the front wheel of the vehicle can be avoided from being transmitted through the first main body 11 and can be directly transmitted to the walking wheel 1232, which effectively improves the deformation problem of the first main body 11 of the heavy-load vehicle transporter and improves the carrying capacity of the vehicle transporter.

[0075] Furthermore, by means of an articulated connection between the first body 11 and the second body 21, and by providing support wheels 50 on both sides of the articulated position, when the vehicle transporter travels to an uneven area, the first body 11 and the second body 21 can rotate to adapt to the ground, thereby preventing a certain traveling mechanism of the heavy-loaded vehicle transporter from being suspended and idling.

[0076] Moreover, the above-mentioned heavy-load vehicle carrier connecting frame 1233 and the walking frame 1231 are rotatably connected via a pin shaft, so that the walking frame 1231 can swing relative to the connecting frame 1233 when traveling in an area with uneven ground, which not only improves the stability of the connecting frame 1233, reduces the vibration and deformation of the vehicle carrier caused by the uneven ground during walking, but also increases the walking capacity of the walking mechanism, and avoids the situation where a certain walking wheel 1232 is suspended and slipping due to the uneven ground during walking.
