[0045] Please refer to Figures 1-2 . Figure 1 is a structural schematic view of an embodiment of a vehicle mover provided in the present application; Figure 2 is Figure 1 is a partial exploded view of the transport mother vehicle shown in the present application.

[0046] The transport mother vehicle 10 includes a trolley frame 100, a driving mechanism 200, and a lifting platform 300.

[0047] The trolley frame 100 includes a base frame 110 and two side supports 120 connected to opposite sides of the base frame 110, respectively. One end of each of the two side supports 120 is fixedly connected to the base frame 110, and the other end of each of the two side supports 120 extends towards the upper end of the base frame 110.

[0048] The driving mechanism 200 is mounted on the trolley frame 100, and the driving mechanism 200 comprises a power assembly 210 and a plurality of connecting belts 220. The first end 221 of each connecting belt 220 is connected with the power output end of the power assembly 210, and the second end 222 of each connecting belt 220 extends towards the direction of the base frame 110 after passing through the top end of the two side supports 120 and is connected with the side end of the lifting platform 300. The power output end of the power assembly 210 is driven to rotate forward or reversely to drive the second end 222 of the connecting belt 220 to move towards the direction of approaching or moving away from the base frame 110, so as to realize the lifting of the lifting platform 300.

[0049] Therefore, by adopting the second end 222 of the plurality of connecting belts 220 extending towards the direction of the base frame 110 after passing through the top end of the two side supports 120 and being connected with the side end of the lifting platform 300, and then driving the first end 222 of the connecting belt 220 to move by the power assembly 210 to realize the lifting or lowering of the lifting platform 300 to the preset height, the vehicle (transportation sub-vehicle or vehicle to be transported) carried on the lifting platform 300 can be lifted or lowered to the preset height, so that the vehicle can be simply and directly lifted to the preset height for parking.

[0050] Further, in the embodiment, by adopting the second end 222 of the connecting belt 220 passing through the top end of the side support 120 and being connected with the lifting platform 300, the part of the second end 222 of the connecting belt 220 to the top end of the side support 120 can be vertically arranged, so that the tensile stress of the connecting belt 220 can be ensured to be stable when the lifting platform 300 is lifted to any height, thereby enabling the lifting control of the lifting platform 300 to be flexible and stable, and the structure to be simple and low in cost.

[0051] Each top end of the side support 120 can comprise two driven rollers 121, and the two driven rollers 121 are rotatably mounted at the top end of the side support 120 and are arranged in parallel and at intervals on each side support 120. The connecting belt 220 can be four, and the second end of each connecting belt 220 can extend vertically downwards to be connected with the lifting platform 300 after passing through one of the driven rollers 121.

[0052] That is, the connecting belts 220 passing through the two driven rollers 121 at the top end of the same side support 120 can be connected to different positions on the same side of the lifting platform 300. By connecting the four connecting belts 220 to the opposite sides of the lifting platform 300 (each side of the lifting platform 300 is connected with two connecting belts 220), the stability of the lifting platform 300 during lifting can be improved.

[0053] The connecting points of the four connecting belts 220 with the lifting platform 300 can form a rectangle.

[0054] In the embodiment, the connecting belt 220 is a chain, and a gear can be arranged on the driven roller 121. When the connecting belt 220 passes the driven roller 121, the connecting belt 220 can be engaged with the gear on the driven roller 121.

[0055] Please refer to Figures 2-4 , Figure 3 is Figure 2 a structural schematic diagram of an embodiment of the driving mechanism;

[0056] Figure 4 is Figure 3 a partial enlarged view of the driving mechanism in the II region.

[0057] In the embodiment, the power device 211 and the driving connection assembly 212 of the power assembly 210.

[0058] The driving connection assembly 212 includes a first rotating shaft 213, a second rotating shaft 214, and an annular driving chain 215.

[0059] The first rotating shaft 213 and the second rotating shaft 214 are parallel, spaced, and rotatably installed on the chassis 110. The annular driving chain 215 is sleeved on the first rotating shaft 213 and the second rotating shaft 214 and is engaged with the first rotating shaft 213 and the second rotating shaft 214. The power output end of the power device 211 is connected to any one of the first rotating shaft 213 and the second rotating shaft 214. The power device 211 drives one of the first rotating shaft 213 and the second rotating shaft 214 to rotate, and drives the other of the first rotating shaft 213 and the second rotating shaft 214 to rotate synchronously through the annular driving chain 215. The first end 221 of the connecting belt 220 is connected to the annular driving chain 215.

[0060] Therefore, in the scheme, the annular driving chain 215 is sleeved on the first rotating shaft 213 and the second rotating shaft 214 to form the driving connection assembly 212. The first end 221 of the connecting belt 220 is connected to the annular driving chain 215. Therefore, when the power device 211 drives the first rotating shaft 213 or the second rotating shaft 214 to rotate forward or reverse, the second end 222 of the connecting belt 220 can move towards or away from the chassis 110, so that the lifting platform 300 can be driven to lift.

[0061] Optionally, the annular driving chain 215 includes a connecting block 2151 and two sub-annular chains 2152 arranged at intervals. The two ends of the connecting block 2151 are respectively connected to the two sub-annular chains 2152.

[0062] The two sub-ring chains 2152 are sleeved on the first rotating shaft 213 and the second rotating shaft 214, and are arranged in parallel and at intervals. The connecting block 2151 is arranged between the two sub-ring chains 2152, so as to connect the two sub-ring chains 2152, and the two sub-ring chains 2152 rotate synchronously with the first rotating shaft 213 or the second rotating shaft 214.

[0063] The first end 221 of the connecting belt 220 is located between the two sub-ring chains 2152, and the first end 221 of the connecting belt 220 is connected to the connecting block 2151.

[0064] The first rotating shaft 213 is provided with two spaced first gear portions, one end of each of the two sub-ring chains 2152 is engaged with the two first gear portions. The second rotating shaft 214 is provided with two spaced second gear portions, the other end of each of the two sub-ring chains 2152 is engaged with the two second gear portions. The first end of the connecting belt 220 is located between the two sub-ring chains 2152, and the first end 221 of the connecting belt 220 is connected to the connecting block 2151.

[0065] In the embodiment, the two sub-ring chains 2152 are connected to the connecting block 2151 to form the ring driving chain 215, which can improve the stability of the ring driving chain 215 rotating with the first rotating shaft 213 and the second rotating shaft 214, and further can stabilize the movement of the connecting belt 220.

[0066] In the embodiment, two connecting belts 220 can be connected to one ring driving chain 215. The two connecting belts 220 can be arranged corresponding to the two spaced driven rollers 121 included in the top end of one side support 120.

[0067] The number of the driving connection assemblies 212 is two, and the two driving connection assemblies 212 are arranged corresponding to the two side supports 120. The two driving connection assemblies 212 can be arranged at the bottom of the two side supports 120.

[0068] The first rotating shaft 213 and the second rotating shaft 214 in each driving connection assembly 212 are arranged corresponding to the two driven rollers 121 on the corresponding side support 120.

[0069] The two connecting belts 220 are connected to each driving connection assembly 212. The first end of each of the two connecting belts 220 is connected to the ring driving chain 215, and the second end of each of the two connecting belts 220 is connected to different positions of the lifting platform 300 after being wound around the two driven rollers 121.

[0070] Specifically, each driving connection assembly 212 further includes a third rotating shaft 216.

[0071] The third rotating shaft 216 can be arranged above the second rotating shaft 214. The first end 221 of one of the connecting belts 220 can be connected to the annular driving chain 215 after passing through the third rotating shaft 216, and the first end 221 of the other connecting belt 220 can be connected to the annular driving chain 215 after passing through the first rotating shaft 213.

[0072] The connecting points of the first ends 221 of the two connecting belts 220 on the driving chain 215 can be located on opposite sides of the plane in which the axis of the first rotating shaft 213 and the axis of the second rotating shaft 214 lie, respectively. Thus, the second ends of the two connecting belts 220 can be moved synchronously in the direction of approaching or moving away from the base frame 110 under the driving of the same driving chain 215, thereby achieving automatic lifting of the lifting platform 300.

[0073] Optionally, the number of the connecting blocks 2151 can be two, and the two connecting blocks 2151 are arranged on opposite sides of the plane in which the axis of the first rotating shaft 213 and the axis of the second rotating shaft 214 lie, respectively. The first ends 221 of the two connecting belts 220 can be connected to the two connecting blocks 2151, respectively.

[0074] Further, in this embodiment, the third rotating shaft 216 is provided with a third gear portion, and the third gear portion on the third rotating shaft 216 can be arranged corresponding to the region between the two second gear portions on the second rotating shaft 214. The first end 221 of one of the connecting belts 220 is connected to the connecting block 2151 (the connecting block 2151 located on the upper side of the plane in which the axis of the first rotating shaft 213 and the axis of the second rotating shaft 214 lie) between the two sub-annular chains 2152 after passing through the third gear portion on the third rotating shaft 216. The first end 221 of the connecting belt 220 is also engaged with the third gear portion on the third rotating shaft 216.

[0075] In this embodiment, a fourth gear portion 2131 is further arranged between the two first gear portions of the first rotating shaft 213. The first end 221 of the other connecting belt 220 is connected to the other connecting block 2151 (the connecting block 2151 located on the lower side of the plane in which the axis of the first rotating shaft 213 and the axis of the second rotating shaft 214 lie) after passing through the fourth gear portion 2131. The first end 221 of the connecting belt 220 is also engaged with the fourth gear portion 2131.

[0076] Further, in the embodiment, the two connecting blocks 2151 can also play a role of cutting off the movement stroke of the connecting belts 220. For example, with one of the connecting blocks 2151 located on the side of the plane where the axis of the first rotating shaft 213 and the axis of the second rotating shaft 214 are located, and with the first end 221 of one of the connecting belts 220 connected to the connecting block 2151 after passing through the third gear part on the third rotating shaft 216, when the connecting block 2151 moves to the position corresponding to the third rotating shaft 216 or the first rotating shaft 213, the third gear on the third rotating shaft 216 and the fourth gear part 2131 on the first rotating shaft 213 can both limit the movement of the connecting block 2151, so as to avoid the second end of the connecting belt 220 from being lifted too high or lowered too low.

[0077] Further, please refer to Figure 3 and Figure 4 The power assembly 210 further comprises a synchronous connecting rotating shaft 217, wherein the synchronous connecting rotating shaft 217 is rotatably installed on the base frame 110, and the two ends of the synchronous connecting rotating shaft 217 are respectively connected to the second rotating shaft 214 in the two driving connecting assemblies 212. That is to say, the two driving connecting assemblies 212 are respectively located on the opposite sides of the synchronous connecting rotating shaft 217, and one end of the synchronous connecting rotating shaft 217 is connected to the second rotating shaft 214 in one of the driving connecting assemblies 212, and the other end of the synchronous connecting rotating shaft 217 is connected to the second rotating shaft 214 in the other driving connecting assembly 212, so as to make the second rotating shafts in the two driving connecting assemblies 212 rotate synchronously. Further, the annular driving chains 215 on the two driving connecting assemblies 212 can move synchronously, so as to ensure that the second ends 222 of the four connecting belts 220 connected by the driving connecting assemblies 212 can be lifted or lowered synchronously, thereby ensuring the stability of the lifting control of the lifting platform 300.

[0078] In addition, the driving connection system formed by the connecting belts 220 and the annular driving chains 215 can occupy a small space area, and a large amount of space is reserved for placing batteries, thereby increasing the endurance time of the transport mother vehicle 10.

[0079] Further, please refer to Figure 2 and Figure 5 , Figure 5 is a structural schematic view of a lifting platform in the transport mother vehicle shown in Figure 2 . Figure 6 is a partial enlarged view of the lifting platform shown in Figure 5 in the III area.

[0080] Each side support 120 comprises two support columns 122 arranged at intervals, and the two driven rollers 121 are rotatably mounted at the top ends of the two support columns 122. Optionally, the top ends of the two support columns 122 in the same side support 120 can be connected by a fixed rod, so as to improve the support stability of the whole side support 120.

[0081] Each side of the lifting platform 300 is provided with at least two connecting platforms 302, and on the same side of the lifting platform 300, the two connecting platforms 302 can be arranged respectively corresponding to the two support columns 122 on the same side, so that each connecting platform 302 is connected with the second end 222 of the two connecting belts 220 around the top ends of the two support columns 122.

[0082] Optionally, on the same side of the lifting platform 300, the two connecting platforms 302 can be arranged on the side away from each other of the two support columns 122 on the same side, i.e. the two support columns 122 are located between the two connecting platforms 302 on the same side of the lifting platform 300. In this scheme, the two support columns 122 and the two connecting platforms 302 on the same side of the lifting platform 300 can form a limiting clamping cooperation, so as to limit the position of the lifting platform 300 in the horizontal direction, avoid the swinging of the lifting platform 300 in the horizontal direction, and further improve the stability of the lifting of the lifting platform 300.

[0083] In addition, by arranging the two side supports 120 to each comprise two support columns 122, the four sides of the chassis 110 can have openings, i.e. the vehicle or the transport sub-car can drive from any side of the chassis 110 to the lifting platform 300.

[0084] Please further refer to Figure 2 、 Figure 5 and Figure 6 .

[0085] In this embodiment, the bearing surface 301 of the lifting platform 300 can be used to bear the vehicle.

[0086] Optionally, the bearing surface 301 of the lifting platform 300 can directly bear the vehicle, so as to directly drive the lifting of the vehicle. Alternatively, a transport sub-car can be used to lift the vehicle, and the vehicle can be carried to the bearing surface 301 of the lifting platform 300 by the transport sub-car, i.e. the lifting of the lifting platform 300 can drive the synchronous lifting of the transport sub-car and the vehicle, so as to realize the automatic parking or taking out of the vehicle.

[0087] In the embodiment, the transition mechanism 303 can be arranged on the lifting platform 300, and the transition mechanism 303 can be used to form a lap joint when the lifting platform 300 is lifted or lowered to a preset height, so as to connect the lifting platform 300 and a movement plane at the corresponding height, and thus the vehicle or the transport sub-vehicle can be driven to move from the bearing surface 301 of the lifting platform 300 to the movement plane along the lap joint.

[0088] The transition mechanism 303 comprises a driving push rod mechanism 310 and a rotating flap 320.

[0089] The driving push rod mechanism 310 comprises a driving member 311 and a movable block 312. The movable block 312 is movably arranged on the lifting platform 300, and the driving end of the driving member 311 is connected to the movable block 312 to drive the movable block 312 to move relative to the lifting platform. The movable block 312 is provided with an inclined surface 3121 inclined to the bearing surface. The rotating flap 320 is rotatably arranged on the lifting platform 300, and one end of the rotating flap 320 abuts against the inclined surface 3121. The movable block 312 is driven to move relative to the lifting platform 300, so that one end of the rotating flap 320 moves along the inclined surface 3121, and thus the other end of the rotating flap 320 is rotated relative to the lifting platform 300. When the other end of the rotating flap 320 is rotated beyond the lifting platform 300, the other end of the rotating flap 320 is used to drive the vehicle or the transport sub-vehicle carried on the lifting platform 300 to move out of the lifting platform along the rotating flap 320.

[0090] Specifically, in the embodiment, the driving member 311 can be a driving power device such as a motor or a hydraulic cylinder, and the driving member 311 is fixedly arranged on the lifting platform 300. The output end of the driving member 311 is connected to the movable block 312 through a driving rod 3111. The movable block 312 is further provided with a roller 3122, and the driving member 311 can drive the movable block 312 to move back and forth along the axis direction of the driving rod 3111 on the lifting platform 300 through the driving rod 3111.

[0091] The middle part of the rotating flap 320 is rotatably arranged at the edge position of the lifting platform 300. One end of the rotating flap 320 is arranged towards the inner side of the lifting platform 300, and the other end of the rotating flap 320 is arranged towards the outer side of the lifting platform 300.

[0092] The roller 321 is arranged below one end of the rotating flap 320 towards the inner side of the lifting platform 300, and the roller 321 is rotatably arranged at the one end of the rotating flap 320. The roller 321 of the rotating flap 320 can be arranged corresponding to the inclined surface 3121 of the movable block 312.

[0093] When the driving member 311 drives the movable block 312 to move in the direction towards the inner side of the lifting platform 300, the rolling wheel 321 at one end of the rotating flap 320 can be lifted along the inclined surface 3121 of the movable block 312, so that the other end of the rotating flap 320 rotates downwards until the other end of the rotating flap 320 rotates to the preset moving plane, thereby forming a connection path between the carrying surface 301 of the lifting platform 300 and the moving plane through the rotating flap 320, so that the transport sub-vehicle or vehicle on the carrying surface 301 of the lifting platform 300 can directly drive along the rotating flap 320 to the moving plane.

[0094] When the transport sub-vehicle or vehicle on the carrying surface 301 of the lifting platform 300 is directly driven along the rotating flap 320 to the moving plane, the driving member 311 drives the movable block 312 to move in the direction towards the outer side of the lifting platform 300, at this time, the end of the rotating flap 320 provided with the rolling wheel 321 can make the rolling wheel 321 descend along the inclined surface 3121 of the movable block 312 under the action of gravity, so that the other end of the rotating flap 320 rotates upwards, so that the other end of the rotating flap 320 rotates to be located in the orthographic projection of the lifting platform 300, thereby avoiding the problem that the rotating flap 320 interferes with other external components when the lifting platform 300 is lifted.

[0095] Please further refer to Figure 6 and Figure 7 , Figure 7 is Figure 5 the cooperation schematic view of the movable block and the rotating flap in the lifting platform shown in FIG. 1.

[0096] In this embodiment, the top of the inclined surface 3121 of the movable block 312 is also connected with a support surface 3123 parallel to the carrying surface 301, wherein the rolling wheel 321 on the rotating flap 320 can move to the support surface 3123 along the inclined surface 3121.

[0097] When the rolling wheel 321 on the rotating flap 320 can move to the support surface 3123 along the inclined surface 3121, the upper layer of the rotating flap 320 can be located in the same plane as the carrying surface 301.

[0098] Further, in this embodiment, a plurality of rotating flaps 320 are provided at the edge area of the lifting platform 300, and similarly, each rotating flap 320 can be provided with a movable block 312, and the driving member 311 can synchronously drive a plurality of movable blocks 312 to move synchronously, so that the plurality of rotating flaps 320 provided at the edge area of the lifting platform 300 can rotate synchronously.

[0099] Specifically, the driving component 311 can be connected to the movable rod 313 via the driving rod 3111, and multiple driving rods 3111 can be connected to the movable rod 313. The movable rod 313 can be movably mounted on the lifting platform 300. The driving component 311 can drive the movable rod 313 to move back and forth along the long side of the preset lifting platform 300, thereby driving multiple movable blocks 312 to move synchronously, and in turn, driving multiple rotating flaps 320 to rotate synchronously through the multiple movable blocks 312.

[0100] Furthermore, in this embodiment, a steering wheel 111 is also installed on the bottom surface of the base frame 110. There are multiple steering wheels 111, and the multiple steering wheels 111 can support the base frame 110.

[0101] In this embodiment, each steering wheel 111 has an independent power unit. By cooperating with multiple steering wheels 111, the entire transport vehicle 10 can move and turn along a preset route.

[0102] Multiple steering wheels 111 can be detachably installed on the side of the base frame 110.

[0103] Furthermore, based on the same inventive concept, this application also provides a vehicle transporter.

[0104] Please see Figure 8 , Figure 8 This is a structural schematic diagram of an embodiment of a vehicle transporter provided in this application.

[0105] The vehicle transporter 40 includes a transport trolley 410 and a transport mother vehicle 10 as described above.

[0106] In this embodiment, the transport trolley 410 can lift a preset vehicle and transport the vehicle to the lifting platform 300 of the transport mother vehicle 10, and the transport trolley 410 is supported by the bearing surface 301 on the lifting platform 300.

[0107] Then, the transport mother car 10 can transport the transport trolley 410 and the vehicles carried on it to a preset location for parking.

[0108] The mother vehicle 10 can lift the transport trolley 410 and the vehicles it carries to a preset height, so that the vehicles can be parked in parking spaces at different heights.

[0109] Please see Figure 9 , Figure 9 Is adopted Figure 8 The diagram shows a vehicle transporter performing a parking operation.

[0110] In this embodiment, the transport trolley 410 can lift and hold the vehicle to be parked at a preset position and transport the vehicle to the lifting platform 300 of the transport mother vehicle 10. Then, the transport mother vehicle 10 can be driven by its steering wheel 111 to travel along a preset trajectory to the position of the preset parking garage 420, wherein the transport mother vehicle parking garage 420 can have at least two floors, and each floor has a vehicle parking space 421 for parking vehicles.

[0111] Furthermore, if no vehicles are parked on the first floor of the parking garage 420, the lifting platform 300 of the transport mother vehicle 10 does not need to be lifted, and the transport trolley 410 on it can directly transport the vehicles to the first floor of the parking garage 420 for parking. When there are vehicles parked on the first floor of the parking garage 420, the lifting platform 300 of the transport mother vehicle 10 can lift the transport trolley 410 to a preset height, corresponding to the parking space 421 on the upper floor of the parking garage 420, and then transport the vehicles to the parking space 421 on that floor of the parking garage 420 for parking.

[0112] In summary, the present application provides a transport mother car and a vehicle transporter. By employing multiple connecting belts, the second ends of which wrap around the tops of two side supports and extend towards the base frame, connecting to the side ends of the lifting platform, a power assembly drives the first ends of the connecting belts to move, thereby raising or lowering the lifting platform to a preset height. This allows the vehicle (transport trolley or vehicle to be transported) carried on the lifting platform to be raised or lowered to the preset height, enabling simple and direct parking of the vehicle at the preset height. Furthermore, by using connecting belts whose second ends wrap around the tops of the side supports and connect to the lifting platform, the portion of the connecting belt from the second end to the top of the side supports is vertically positioned. Therefore, the tensile stress on the connecting belts remains stable when the lifting platform is raised to any height, resulting in flexible and stable lifting control of the lifting platform, and a simple and low-cost structure.

[0113] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
