Description

Technical Field

[0001] The present invention belongs to the technical field related to vehicle transport, and in particular relates to a vehicle transporter and a vehicle transport component. Background Art

[0002] With the increasing popularity of multi-story parking garages in China, highly automated flat-type mobile parking garages are increasingly being adopted by the market due to their convenient parking and fast access to vehicles. In flat-type mobile parking garages, vehicle transporters are one of the main components.

[0003] Among them, the split type of vehicle transporter is a structure commonly used in the market. Its main structural feature is that the front and rear transport units are separately set, which are used to transport the front and rear wheels of the vehicle respectively. The two transport units are connected by cables such as drag chains or swing arms. Each transport unit has an independent walking system and clamping arm system, so that the vehicle transporter can adjust the distance between the two transport units according to the different wheelbases of the vehicles. Since the two transport units each have a set of walking systems, when the clamping arm system of the transport unit clamps the front and rear wheels of the vehicle and walks, the two transport units cannot achieve relative mechanical locking. In this way, when one of the transport units slips during start-stop acceleration, or when the motors in the walking systems of the two transport units are out of sync due to a fault, the vehicle tire may slip out of the clamping arm of the corresponding transport unit, which will cause the vehicle transporter to stop running due to abnormal data fed back by the detection device, which will seriously affect the transport efficiency of the vehicle transporter. Summary of the invention

[0004] In view of this, it is necessary to provide a vehicle transporter and a vehicle transport assembly to solve the technical problem that the spacing between the two separate transport units cannot be locked after adjustment.

[0005] A vehicle carrier, the vehicle carrier comprising:

[0006] The carrier body includes two carrier units which are arranged in a front and rear separated manner, wherein each of the carrier units includes a frame body;

[0007] An adjustment assembly, comprising a pull rod arranged across the two frame bodies, the pull rod being slidably connected to the frame body of at least one of the transport units, and being used to guide the relative movement between the two transport units;

[0008] A locking mechanism corresponding to at least one of the two frame bodies, the locking mechanism being mounted on the frame body slidably connected to the pull rod, and the locking mechanism being able to act on a portion of the frame body corresponding to the pull rod, for controlling the locking / unlocking of the pull rod on the corresponding frame body;

[0009] When the locking mechanism locks the pull rod on the corresponding frame body, the distance between the two transport units is locked.

[0010] It can be understood that the relative movement between the two transport units is guided by the sliding connection between the pull rod and the frame body, and the pull rod is mechanically locked by the locking mechanism to achieve the locking of the distance between the two transport units. In this way, on the one hand, the pull rod can be used to guide and support the frame body, so that the corresponding transport unit can omit the structure of the front and rear driven wheel groups and the side guide wheel groups, thereby reducing costs; on the other hand, it can also ensure the synchronization of the movement of the two transport units, avoiding the situation where the vehicle tires of the vehicle transporter slip out of the robot arm when transporting the vehicle, thereby improving the transport efficiency of the vehicle transporter and reducing costs.

[0011] In one of the embodiments, the pull rod is provided with a plurality of fixing holes in sequence along the length direction of the pull rod;

[0012] Wherein, the locking mechanism at least includes a sprocket and a driving assembly, the sprocket is rotatably mounted on the frame body, and the sprocket teeth on the sprocket can be snap-fitted with the fixing hole.

[0013] It can be understood that by utilizing the snap-fitting fit between the sprocket teeth on the sprocket and the fixing holes on the pull rod, the vehicle transporter can be operated by simply controlling the opening / closing of the drive assembly to achieve control of the locking of the pull rod on the frame body, thereby automating the control of the spacing between the two transport units.

[0014] In one embodiment, the locking mechanism also includes a locking head transmission-connected to the driving assembly, and the locking head can be driven by the driving assembly to enter a concave cavity enclosed between two adjacent sprocket teeth on the sprocket, so as to limit the circumferential position of the sprocket to the pull rod and lock the pull rod.

[0015] In one embodiment, the driving assembly includes a telescopic driving member and a push rod, and the lock head is connected to the telescopic rod of the telescopic driving member through the push rod;

[0016] Wherein, the push rod can perform telescopic movement relative to the horizontal center line of the sprocket wheel under the drive of the telescopic driving member.

[0017] It can be understood that by driving the telescopic movement of the push rod using the telescopic drive member, the lock head can be adaptively adjusted relative to the sprocket under the drive of the push rod, which can ensure that the lock head can enter the concave cavity enclosed between two adjacent sprocket teeth of the sprocket and lock the sprocket circumferentially.

[0018] In one embodiment, the driving assembly further includes an elastic member, wherein the elastic member is installed between the push rod and the lock head, and the push rod can push the lock head toward the sprocket through the elastic member.

[0019] It is understandable that the elastic deformation of the elastic member can buffer the driving of the telescopic drive member to move the lock head toward the sprocket, thereby preventing the telescopic drive member from being damaged due to obstruction.

[0020] In one embodiment, the lock head includes a limiting rod, and the lock head can limit the sprocket wheel circumferentially to the pull rod through the limiting rod;

[0021] Among them, a sprocket fixing frame is fixedly installed on the frame body, the sprocket is rotatably installed in the sprocket fixing frame, and a slot is opened on the sprocket fixing frame, and the slot is connected with the concave cavity; and when the limit rod limits the sprocket circumferentially to the pull rod, the limit rod can be engaged with the slot.

[0022] It can be understood that, by utilizing the snap fit between the limit rod and the slot on the sprocket fixing frame, the sprocket fixing frame can provide support for the limit rod to limit the circumferential position of the sprocket, thereby ensuring the stability of the lock when locking the sprocket.

[0023] In one embodiment, the adjustment assembly further comprises a sliding connection member, the pull rod is arranged through the sliding connection member and is slidably connected to the sliding connection member, and the locking mechanism can act on a portion of the pull rod extending out of the sliding connection member;

[0024] Wherein, the sliding connectors are respectively installed on the two frame bodies.

[0025] In one embodiment, the manipulator further includes a walking wheel mechanism and a clamping arm mechanism, and the walking wheel mechanism and the clamping arm mechanism are both installed on the frame body;

[0026] The clamping arm mechanism comprises four manipulator clamping arms, two of which form a group, and the two groups of manipulator clamping arms are respectively used to clamp the vehicle tires;

[0027] The walking wheel mechanism comprises two walking wheel groups, and each of the walking wheel groups is arranged between two of the manipulator clamping arms in each group of the manipulator clamping arms.

[0028] In one embodiment, the walking wheel mechanism further includes a walking wheel driving assembly, and the walking wheel driving assembly is arranged between the two walking wheel assemblies and is respectively connected to the two walking wheel assemblies by transmission;

[0029] The clamping arm mechanism also includes two clamping arm driving assemblies, which are arranged on the two outer sides of the walking wheel driving assembly and are respectively connected to the two manipulator clamping arms located on the same side of the walking wheel assembly.

[0030] It can be understood that the travel wheel drive assembly and the clamp arm drive assembly are staggered so that the arrangements of the travel wheel drive assembly and the clamp arm drive assembly do not affect each other in the height direction of the frame body, which can reduce the overall height dimension of the manipulator.

[0031] In addition, the present application also provides a vehicle transport assembly, including a walking guide rail and the above-mentioned vehicle transporter;

[0032] The two frame bodies are respectively slidably matched with the travel guide rails, and the vehicle carrier can travel along the extension direction of the travel guide rails.

[0033] It can be understood that by utilizing the sliding fit between the frame body and the travel guide rail, the vehicle carrier can define a travel path through the travel guide rail during operation, thereby eliminating the need for driven wheel sets around the frame body.

[0034] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0035] The vehicle transporter and vehicle transport assembly for which protection is sought in the present application use a sliding connection between a pull rod and a frame body to guide the relative movement between the two transport units, and use two locking mechanisms to mechanically lock the pull rod to achieve locking of the spacing between the two transport units. In this way, on the one hand, the pull rod can be used to guide and support the two frame bodies, so that the corresponding transport units can omit the structure of the front and rear driven wheel groups and the side guide wheel groups, thereby reducing costs; on the other hand, the synchronization of the movement of the two transport units can be ensured, thereby preventing the vehicle tires from slipping off the manipulator when the vehicle transporter is transporting the vehicle, thereby improving the transport efficiency of the vehicle transporter and reducing costs.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] It should be noted that when an element is referred to as being "provided on" another element, it may be directly provided on the other element or there may be a central element. When an element is considered to be "provided on" another element, it may be directly provided on the other element or there may be a central element at the same time. When an element is considered to be "fixed to" another element, it may be directly fixed to the other element or there may be a central element at the same time.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0053] The vehicle transporter 100 for which protection is sought in the present application specifically refers to an AGV vehicle used in a stereo garage for storing and retrieving cars.

[0054] like Figure 1 As shown, the vehicle transporter 100 provided in the present application includes a transporter body, an adjustment assembly 20 and two locking mechanisms 30. The transporter body includes two transport units 10 that are separated into front and rear parts, wherein each transport unit 10 includes a frame body 11; the adjustment assembly 20 includes a pull rod 21 that is arranged across the two frame bodies 11, and the pull rod 21 is slidably connected to the frame body 11 of at least one of the transport units 10, and is used to guide the relative movement between the two transport units 10; the locking mechanism 30 corresponds to at least one of the two frame bodies 11, and the locking mechanism 30 is installed on the frame body 11 that is slidably connected to the pull rod 21, and the locking mechanism 30 can act on the part of the frame body 11 corresponding to the pull rod 21, and is used to control the locking / unlocking of the pull rod 21 on the corresponding frame body 11; when the locking mechanism 30 locks the pull rod 21 on the corresponding frame body 11, the spacing between the two transport units 10 is locked. Here, the relative movement between the two transport units 10 specifically refers to the two transport units 10 moving toward each other or in the opposite direction to adjust the distance between the two transport units 10, so that the vehicle transporter 100 can be suitable for transporting vehicles with different wheelbases. It should be noted that the two transport units 10 in the vehicle transporter 100 of the present application are respectively used to clamp the front wheels and rear wheels of the vehicle to jointly complete the transportation of the vehicle; of course, the working principle of how the two transport units 10 cooperate with each other and move synchronously when working can adopt the conventional method of existing vehicle transporters, which will not be elaborated here.

[0055] As can be seen from the above, when the vehicle transporter 100 of the present application is working, the sliding connection between the pull rod 21 and the frame body 11 can be used to guide the relative movement between the two transport units 10, and the two locking mechanisms 30 can be used to mechanically lock the pull rod 21 to achieve the locking of the distance between the two transport units 10. In this way, on the one hand, the pull rod 21 can be used to guide and support the frame body 11, so that the corresponding transport unit 10 can omit the structure of the front and rear driven wheel groups and the side guide wheel groups, thereby reducing costs; on the other hand, it can also ensure the synchronization of the movement of the two transport units 10, thereby avoiding the situation where the vehicle tires of the vehicle transporter 100 slip off the transport unit 10 when transporting the vehicle, thereby improving the transport efficiency of the vehicle transporter 100 and reducing costs.

[0056] It should be noted that, since the locking mechanism 30 and the corresponding parts on the pull rod 21 are both arranged on the frame body 11 after the spacing between the two transport units 10 in the vehicle transporter 100 of the present application is adjusted, the space between the two transport units 10 will not be occupied. In this way, when the vehicle transporter 100 is working, the minimum spacing between the two transport units 10 is when the two frame bodies 11 of the two transport units 10 are against each other, so that the range of adjusting the spacing between the two transport units 10 in the vehicle transporter 100 is larger, so as to adapt to a wider range of vehicle models with different wheelbases. Here, when the vehicle transporter 100 is working, the minimum spacing of the front and rear wheels of the vehicle can reach 1880mm, and the maximum spacing can reach 3400mm.

[0057] like Figure 1 As shown, in one embodiment, the pull rod 21 is slidably connected to the frame bodies 11 of the two transport units 10, and accordingly, the number of the locking mechanisms 30 is configured to be two, and the two locking mechanisms 30 are installed on the frame bodies 11 of the two transport units 10. The pull rod 21 can guide and support the two frame bodies 11 respectively; and the locking of the distance between the two transport units 10 can be completed by the two locking mechanisms 30. It can be understood that in other embodiments, the pull rod 21 can also be slidably connected to the frame body 11 of one of the transport units 10 and fixedly connected to the frame body 11 of the other transport unit 10, and accordingly, the number of the locking mechanism 30 is one.

[0058] like Figure 2 , Figure 3 As shown, in one embodiment, the transport unit 10 further includes a walking wheel mechanism 12 and a clamping arm mechanism 13, both of which are mounted on the frame body 11; wherein the clamping arm mechanism 13 includes four manipulator clamping arms 131, two manipulator clamping arms 131 form a group, and the two groups of manipulator clamping arms 131 are respectively used to clamp the vehicle wheels; the walking wheel mechanism 12 includes two walking wheel groups 121, and each walking wheel group 121 is arranged between two manipulator clamping arms 131 in each group of manipulator clamping arms 131. That is to say, the walking wheel group 121 of the walking wheel mechanism 12 of the transport unit 10 walks on the walking surface, and the two groups of manipulator clamping arms 131 of the clamping arm mechanism 13 are used to clamp the two front wheels or the two rear wheels of the vehicle respectively. Here, the number of walking wheels 1211 in each walking wheel group 121 is two. It can be understood that in other embodiments, the number of walking wheels 1211 in each walking wheel group 121 can also be one, three, or even more, which will not be elaborated here.

[0059] like Figure 6As shown, in this embodiment, each manipulator clamp arm 131 is rotatably mounted on the frame body 11 through a vertical shaft 133, so that each group of manipulator clamp arms 131 for clamping the wheels of the automobile has a folded state close to the two sides of the frame body 11 and a working state perpendicular to the side of the frame body 11. Here, the vertical shaft 133 is set through the swing seat 1311 of the manipulator clamp arm 131. It should be noted that when the manipulator clamp arm 131 is in the folded state, the length of the transport unit 10 does not exceed 1900mm, the width does not exceed 1015mm, and the height does not exceed 95mm, so that the transport unit 10 can freely shuttle between the flush walking surface and the parking surface for parking vehicles in the three-dimensional parking garage.

[0060] like Figure 6 As shown, in one embodiment, the part of the vertical shaft 133 that passes through the manipulator arm 131 downward is rotatably connected to the frame body 11 through the tapered roller bearing 101, and the part of the vertical shaft 133 that passes through the manipulator arm 131 upward is rotatably connected to the frame body 11 through the plane bearing 102. In this way, the structural characteristics of the tapered roller bearing 101 and the plane bearing 102 can be utilized, which can not only ensure the load-bearing capacity of the swing seat 1311 when installed on the frame body 11, but also reduce the overall thickness of the swing seat 1311 when assembled on the frame body 11. Here, the plane bearing 102 is a bronze bearing. It can be understood that in other embodiments, the plane bearing 102 can also be a copper bearing, a rolling bearing, etc., which will not be elaborated here. It should be noted that, since the tapered roller bearing 101 has a large load-bearing capacity, it can meet the load-bearing capacity of the assembly between the vertical rotating shaft 133 and the frame body 11; and the height dimension of the plane bearing 102 is smaller than the height dimension of the tapered roller bearing 101, thereby playing a role in thinning the overall thickness of the connection part.

[0061] like Figures 2 to 4As shown, in one embodiment, the walking wheel mechanism 12 also includes a walking wheel drive assembly 122, which is arranged between the two walking wheel groups 121 and is respectively connected to the two walking wheel groups 121 in transmission, so that when the walking wheel mechanism 12 is working, the walking wheel drive assembly 122 can be used to control the walking of the two walking wheel groups 121 on the walking surface. Here, the walking wheel driving assembly 122 includes a walking motor 1221, a walking reducer 1222, a driving shaft 1223, and two driving gears 1224. The walking motor 1221 and the driving shaft 1223 are arranged in parallel and are connected to the driving shaft 1223 through the walking reducer 1222. The two driving gears 1224 are installed at both ends of the driving shaft 1223. Each driving gear 1224 is meshed with two driven gears (not shown) through gear transmission. Each driven gear is respectively connected to each walking wheel 1211. When the walking wheel driving assembly 122 is working, one walking motor 1221 can realize the motion control of the two walking wheel groups 121 under the transmission of the driving shaft 1223, the driving gear 1224 and the driven gear.

[0062] like Figure 2 , Figure 3 As shown, in one embodiment, the clamping arm mechanism 13 further includes two clamping arm driving assemblies 132, which are arranged on the two outer sides of the walking wheel driving assembly 122 and are respectively connected to the two manipulator clamping arms 131 on the same side of the walking wheel assembly 121. In other words, in this embodiment, the clamping arm driving assembly 132 and the walking wheel driving assembly 122 are staggered on the frame body 11, so that the arrangement of the walking wheel driving assembly 122 and the clamping arm driving assembly 132 does not affect each other in the height direction of the frame body 11, so that the overall height dimension of the transport unit 10 can be reduced. Here, the height space required for the transport unit 10 as a whole to walk on the walking surface is relatively small, not exceeding 95 mm. In this way, when the vehicle transporter 100 is used in a multi-story parking garage, because the overall height of the transport unit 10 is higher than the height from the ground of the vehicle chassis, the transport unit 10 can directly enter the parking surface of the multi-story parking garage from the walking surface of the multi-story parking garage. Therefore, the multi-story parking garage can set the walking surface and the parking surface flush, which can reduce the parking space production cost of the multi-story parking garage and reduce the production difficulty and cost of corresponding supporting components.

[0063] like Figure 5As shown, in one embodiment, the clamp arm driving assembly 132 includes a clamp arm motor 1321, a sprocket chain 1322 and two worms 1323, the clamp arm motor 1321 is connected to the two worms 1323 through the sprocket chain 1322, and each worm 1323 is respectively engaged with the arc teeth 13111 on the swing seat 1311 of the manipulator clamp arm 131, so that when the clamp arm driving assembly 132 is working, one clamp arm motor 1321 can realize the linkage between the corresponding two manipulator clamp arms 131 under the transmission of the sprocket chain 1322 and the two worms 1323, so as to control the manipulator clamp arms 131 to switch back and forth between the folded state and the working state on the frame body 11. Here, the clamp arm motor 1321 is arranged along the travel direction of the transport unit 10.

[0064] like Figure 2 , Figure 3 , Fig.11 , Fig.12 As shown, in one embodiment, the transport unit 10 further includes a control module 14 and a shock absorbing mechanism 15, wherein the control module 14 is mounted on the frame body 11 through the shock absorbing mechanism 15, and is electrically connected to the walking wheel mechanism 12 and the clamping arm mechanism 13 respectively; wherein the shock absorbing mechanism 15 can drive the control module 14 to adjust its position relative to the frame body 11 in the height direction of the frame body 11. That is to say, the transport unit 10 can use the control module 14 to control the specific work of the walking wheel mechanism 12 and the clamping arm mechanism 13, and when the transport unit 10 is moving, the shock absorbing mechanism 15 can be used to dampen and buffer the assembly of the control module 14 on the frame body 11, so as to improve the stability of the electrical connection between the control module 14 and the walking wheel mechanism 12 and the clamping arm mechanism 13, thereby ensuring the stability and control accuracy of the transport unit 10 when working. Here, the control module 14 is specifically electrically connected to the walking motor 1221 in the walking wheel mechanism 12 and the clamping arm motor 1321 in the clamping arm mechanism 13 respectively.

[0065] like Fig.11 , Fig.12As shown, in one embodiment, the shock absorbing mechanism 15 includes a mounting bracket 151 and a plurality of connecting components. The mounting bracket 151 is mounted on the frame body 11 through the plurality of connecting components, and is used to carry the control module 14. Each connecting component includes a screw 152, a spring 153, a nut 154 and a gasket 155. The screw 152 is fixed on the frame body 11, and the portion of the screw 152 that passes through the mounting bracket 151 is screwed with the nut 154. The spring 153 is sleeved on the screw 152 and abuts against the gasket 155 and the frame body 11 respectively, so that the connecting component can elastically support the mounting bracket 151 with the spring 153. In this way, when the transport unit 10 is in motion, if the frame body 11 vibrates, the control module 14 is mounted on the mounting bracket 151 and vibrates together. In this process, the spring 153 can play a role of buffering and shock absorbing for the mounting bracket 151.

[0066] like Figure 2 , Figure 3 , Figure 8 , Fig. 9 As shown, in one embodiment, the adjustment assembly 20 also includes a sliding connector 22, the pull rod 21 is arranged through the sliding connector 22 and is slidably connected to the sliding connector 22, and the sliding connectors are respectively installed on the two frame bodies 11. In other words, the pull rod 21 can be slidably connected to the frame body 11 through the sliding connector 22. Here, the sliding connector 22 is fixed to the frame body 11, and the sliding connector 22 and the pull rod 21 are slidably matched. Preferably, the sliding connector 22 can be a sliding guide rail or a sliding bearing. It should be noted that the locking mechanism 30 of this embodiment can specifically act on the part of the pull rod 21 that extends out of the sliding connector 22 to achieve locking of the pull rod 21 on the frame body 11.

[0067] like Figure 7 , Figure 8 and Fig.10As shown, in one embodiment, the pull rod 21 is sequentially provided with a plurality of fixing holes 211 in the length direction of the pull rod 21; accordingly, the locking mechanism 30 includes a sprocket 31, a locking head 32 and a driving assembly 33, the sprocket 31 is rotatably mounted on the frame body 11, and the sprocket teeth 311 on the sprocket 31 can be snap-fitted with the fixing holes 211; the locking head 32 is transmission-connected with the driving assembly 33, and the locking head 32 can be driven by the driving assembly 33 to enter into a concave cavity 312 enclosed between two adjacent sprocket teeth 311 on the sprocket 31, so as to limit the sprocket 31 circumferentially to the pull rod 21 and lock the pull rod 21. That is to say, the locking mechanism 30 can realize the snap fit between the sprocket teeth 311 on the sprocket wheel 31 that is circumferentially limited and the fixing holes 211 on the pull rod 21 to control the locking / unlocking of the pull rod 21. In this process, only the opening / closing control of the driving assembly 33 is required, so that the automation of the distance control between the two transport units 10 can be realized. Here, when the sprocket wheel 31 rotates on the frame body 11, the sprocket teeth 311 on the sprocket wheel 31 can be snap fit with the fixing holes 211 on the pull rod 21 in sequence along the length direction of the pull rod 21.

[0068] like Figure 7 , Fig.10 As shown, in one embodiment, the lock head 32 includes a limit rod 321, and the lock head 32 can limit the sprocket 31 circumferentially to the pull rod 21 through the limit rod 321; accordingly, a sprocket fixing frame 313 is fixedly mounted on the frame body 11, and the sprocket 31 is rotatably mounted in the sprocket fixing frame 313, and a groove (not shown) is provided on the sprocket fixing frame 313, and the groove is connected to the concave cavity 312; and, when the limit rod 321 limits the sprocket 31 circumferentially to the pull rod 21, the limit rod 321 can engage with the groove. That is to say, the upper limit rod 321 on the lock head 32 can be inserted into the groove of the sprocket fixing frame 313 under the drive of the driving assembly 33, and enter along the depth direction of the groove until it moves into the concave cavity 312 on the sprocket 31. During this process, the bottom of the groove can be used to limit the movement of the limit rod 321, so that the sprocket fixing frame 313 can provide support for the limit rod 321 to limit the circumferential position of the sprocket 31, thereby ensuring the stability of the lock head 32 when locking the sprocket 31.

[0069] like Figure 7 , Fig.10As shown, in one embodiment, the drive assembly 33 includes a telescopic drive member 331 and a push rod 332, and the lock head 32 is connected to the telescopic rod 3311 of the telescopic drive member 331 through the push rod 332; when the drive assembly 33 is working, the telescopic drive member 331 can drive the lock head 32 to move toward the sprocket 31 under the transmission of the push rod 332, and in this process, the push rod 332 plays a role of lengthening transition. Here, the telescopic rod 3311 and the push rod 332 can be connected to each other through the latch 301; wherein, the telescopic drive member 331 is electrically connected to the control module 14 and is controlled by the control module 14, and the telescopic drive member 331 can be specifically an electric push rod, and can be specifically fixed to the frame body 11 through the electric push rod fixing frame 3312. It can be understood that in other embodiments, the telescopic drive member 331 can also be a hydraulic push rod, a telescopic cylinder, etc. It should be noted that the push rod 332 can be slidably mounted on the frame body 11 through a sliding bearing 303.

[0070] like Figure 7 , Fig.10 As shown, in one embodiment, the drive assembly 33 also includes an elastic member 333, which is installed between the push rod 332 and the lock head 32, and the push rod 332 can push the lock head 32 toward the sprocket 31 through the elastic member 333. In this way, the elastic deformation of the elastic member 333 can be used to make the telescopic drive member 331 play a buffering role in driving the lock head 32 toward the sprocket 31, thereby preventing the telescopic drive member 331 from being damaged due to obstruction. It should be noted that the elastic member 333 is configured as a compression spring. Here, the lock head 32 can be limited to the push rod 332 by a fixed screw 302 that passes through the lock head 32 and is threadedly connected to the push rod 332. It can be understood that in other embodiments, the elastic member 333 can be configured as a rubber sleeve or other elastic accessories that can provide elastic force.

[0071] like Fig.10As shown, in this embodiment, the lock head 32 can be driven by the telescopic driving member 331 to perform telescopic movement relative to the horizontal center line of the sprocket 31, so that the lock head 32 can be driven by the push rod 332 to make adaptive adjustment relative to the sprocket 31. Once the upper limit rod 321 of the lock head 32 just hits the sprocket teeth 311 of the sprocket 31, the telescopic rod 3311 continues to drive the push rod 332 to push the lock head 32, and the lock head 32 can use the elastic member 333 to extend and retract at the front end of the push rod 332. During the operation of the vehicle transporter 100 transporting the vehicle, or during the operation, if there is a slight movement difference between the front and rear transport units 10, the sprocket 31 will continue to rotate by an angle until the sprocket 31 is locked by the upper limit rod 321 of the lock head 32, so that the deviation range of the adjusted spacing between the two transport units 10 in the vehicle transporter 100 can be ensured to be about 13 mm. The lock head 32 can enter into the concave cavity 312 enclosed between two adjacent sprocket teeth 311 of the sprocket 31 and lock the sprocket 31 circumferentially.

[0072] In summary, when the vehicle transporter 100 of the present application is picking up a vehicle, the two transport units 10 can enter the bottom of the target vehicle through their respective walking wheel mechanisms 12. When the clamping arm mechanisms 13 on the two transport units 10 are respectively aligned with the front and rear wheels of the target vehicle, the telescopic driving member 331 of the locking mechanism 30 on each transport unit 10 is started under the control of the corresponding control module 14, and the upper limit rod of the push-top lock 32 is clamped into the slot of the sprocket fixing frame 313 and the sprocket 31 is circumferentially locked. By utilizing the action force and reaction force, the sprocket 31 can lock the pull rod 21 to the frame body 11 through the sprocket teeth 311, and the locking of the two transport units 10 is realized; thereafter, the clamping arm mechanisms 13 on the two transport units 10 can be opened from the frame body 11 under the control of their respective control modules 14 to clamp the front and rear wheels of the target vehicle; then, the walking wheel mechanisms 12 on the two transport units 10 are started again, and drive the target vehicle to move together.

[0073] In addition, the present application also provides a vehicle transport assembly, including a running rail (not shown), the above-mentioned vehicle transporter 100, the two frame bodies 11 respectively slide with the running rails, and the vehicle transporter 100 can travel along the extension direction of the running rails. That is to say, during the operation of the vehicle transporter 100, the sliding fit between the frame body 11 and the running rail is utilized so that the vehicle transporter limits the running path through the running rail, which can save the driven wheel set around the frame body 11. Here, a guide groove matching the running rail is provided on the frame body 11, and the guide groove is plug-fitted with the running rail, thereby realizing the sliding fit between the frame body 11 and the running rail.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
