Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] The present application provides a transport carrier 300, see Figures 1 to 4 , Figure 1 It is a structural schematic diagram of the transport mother-child vehicle provided by this application. Figure 2 yes Figure 1 The front view of the transport vehicle. Figure 3 yes Figure 1 The structural diagram of the transport mother vehicle. Figure 4 yes Figure 3 Schematic diagram of the structure of the lifting platform assembly in the transport vehicle after it is raised.

[0044] The transport carrier 300 can be applied to parking lot scenarios to transport vehicles from vehicle entrance positions to parking spaces on each floor, and to transport vehicles in parking spaces to vehicle exit positions.

[0045] The transport mother-and-child vehicle 300 includes a transport mother vehicle 100 and a transport child vehicle 200. The transport mother vehicle 100 carries the transport child vehicle 200. The transport mother vehicle 100 is aligned with the parking space. The transport child vehicle 200 is used to transport vehicles between the parking space and the transport mother vehicle.

[0046] Among them, the transport mother vehicle 100 includes a traveling frame 10, multiple walking mechanisms 20 and a lifting platform assembly 30. The multiple walking mechanisms 20 are arranged on the traveling frame 10 and are used to drive the traveling frame 10 to travel. The lifting platform assembly 30 is arranged on the traveling frame 10 and is used to lift and lower to lift the transport sub-vehicle 200 placed thereon, so that the vehicle carried by the transport sub-vehicle 200 can be transported to a parking space located at a high level.

[0047] See also Figure 1 and Figure 2 The transport vehicle 100 carries the transport sub-vehicle 200 to the vehicle entrance position of the garage. The transport sub-vehicle 200 picks up the vehicle parked at the garage entrance position and transfers it to the transport vehicle 100. The transport vehicle 100 moves to an empty parking space in the garage. If the parking space is a high-rise storage space, the lifting platform assembly 30 is raised and lowered to align with the high-rise storage space. The transport sub-vehicle 200 then transfers the vehicle it carries to the high-rise storage space. After that, the empty transport sub-vehicle 200 returns to the lifting platform assembly 30, and the transport vehicle 100 transports another vehicle to be transported.

[0048] See also Figures 3 to 5 The traveling frame 10 includes a base frame 12 and two side brackets 14 connected to opposite sides of the base frame 12 respectively.

[0049] A plurality of traveling mechanisms 20 are respectively arranged at least at the four corners of the traveling frame 10, and are used to drive the traveling frame 10 to travel and change the traveling direction of the traveling frame 10 without changing the posture of the traveling frame 10. The cooperation of the plurality of traveling mechanisms 20 can make the traveling frame 10 spin in place to adjust the front direction of the transported vehicle.

[0050] The traveling mechanism 20 may be an electrically driven steering wheel which can drive itself and adjust the direction, so that the cooperation of a plurality of electrically driven steering wheels can change the traveling direction of the traveling frame 10 and make the traveling frame 10 spin in place without changing the posture of the traveling frame 10.

[0051] The traveling mechanism 20 may further include a motor and traveling wheels. The motor drives the traveling wheels to rotate. Multiple traveling mechanisms 20 cooperate to drive the traveling frame 10 to travel, and the traveling direction of the traveling frame 10 can be adjusted by differential rotation of each traveling mechanism 20 .

[0052] Furthermore, the transport mother vehicle 100 also includes a plurality of load wheels 22, and the plurality of load wheels 22 are arranged on the base frame 12. The load wheels 22 can also be arranged on the side of the side frame 14 facing the supporting surface (such as the ground, etc.). The load wheels 22 are used to support the traveling frame 10 to walk, so as to share the supporting force borne by the walking mechanism 20, so that the supporting force obtained by the traveling frame 10 is more evenly distributed, and the transport mother vehicle 100 walks more smoothly.

[0053] In this embodiment, the load wheel 22 is a universal wheel, and four electrically driven steering wheels are respectively provided at the four corners of the base frame 12. There are eight load wheels 22, four of which correspond to the four electrically driven steering wheels, and the remaining four load wheels 22 are distributed on the side of the base frame 12 facing the support surface.

[0054] The transport vehicle 100 also includes a plurality of distance detectors 151, which are arranged on the peripheral side of the traveling frame 10. The distance detectors 151 are used to detect the distance between the transport vehicle 100 and obstacles, thereby adjusting the walking trajectories of the plurality of walking mechanisms 20. The distance detectors 151 can also detect the distance between the transport vehicle 100 and the corresponding parking space, so as to facilitate the alignment of the transport vehicle 100 with the parking space and maintain an appropriate distance, thereby facilitating the transport vehicle 200 to load and unload vehicles between the transport vehicle 100 and the parking space.

[0055] The distance detector 151 may be an element capable of detecting distance, such as a distance sensor and a photoelectric sensor.

[0056] For example, on the path of the garage, there is another transport mother car 300 loading or unloading vehicles in front of the walking track of the transport mother car 100, and then the distance detector 151 on the transport mother car 100 detects that the distance between itself and the transport mother car 300 in front reaches the set distance, and it can give a signal to slow down the transport mother car 100, or slow down to stop moving. Or, if the distance detector 151 detects that the transport mother car 100 is close to an obstacle on the side of the walking track and there is a risk of collision, the travel direction of the walking mechanism 20 will be adjusted to change the walking track to avoid the collision.

[0057] The transport vehicle 100 also includes at least two visual detectors 152 , which are respectively disposed on the two side supports 14 for detecting the spatial information directly in front of the corresponding side supports 14 , and thereby adjusting the walking direction of the walking mechanism 20 .

[0058] The visual detector 152 may be a visual sensor, a laser sensor or other element capable of visual detection.

[0059] For example, on the path in the garage, the visual detector 152 detects spatial information in the direction of movement, and the spatial information includes signs on the path ahead, obstacle information on the path, etc. If there is a turn sign on the path, or there is another transport vehicle 100 on the path ahead, the visual detector 152 can send a signal to adjust the walking trajectory of the transport vehicle 100. In other words, it can adjust the walking directions of multiple walking mechanisms 20 at the same time to walk along the trajectory or avoid obstacles.

[0060] The transport vehicle 100 also includes a laser radar positioning sensor 153 , which is disposed on the top of the side bracket 14 away from the base frame 12 . The laser radar positioning sensor 153 is used to determine the position and cruising of the transport vehicle 100 .

[0061] In the garage scene, the locations of the scene roads, vehicle entrances and exits, parking spaces, etc. are all determined, and the control system of the transport vehicle 100 stores a scene map of the garage, so the transport vehicle 100 can move to the corresponding position along the track in the scene map when receiving instructions. The laser radar positioning sensor 153 has the function of determining the position of the transport vehicle 100 in the scene map, so the control system of the transport vehicle 100 can plan its own walking track in real time, thereby realizing the automatic cruising function of the transport vehicle 100.

[0062] Therefore, with the coordinated adjustment of the distance detector 151, the visual detector 152 and the laser radar positioning sensor 153, the transport vehicle 100 can automatically cruise in the garage and adjust the walking trajectory of the transport vehicle 100 in real time, so that the transport vehicle 100 can efficiently transfer vehicles.

[0063] like Figure 4 As shown, the lifting platform assembly 30 is arranged on the base frame 12 and located between the two side brackets 14. The lifting platform assembly 30 is slidably connected to the side brackets 14. The lifting platform assembly 30 moves up and down in the vertical direction of the main surface of the base frame 12 under the limitation of the side brackets 14.

[0064] The transport vehicle 200 is placed on the lifting platform assembly 30 , and can be driven into and out of the lifting platform assembly 30 along a passage formed by two side brackets 14 .

[0065] like Figure 3 As shown, in this embodiment, the two side brackets 14 are each provided with a first guide member 141 on one side opposite to each other, and the lifting platform assembly 30 is correspondingly provided with a second guide member 142. The second guide member 142 is slidably connected to the first guide member 141, and then the lifting platform assembly 30 is lifted and lowered along the first guide member 141, so that the lifting and lowering of the lifting platform assembly 30 is smoother.

[0066] The first guide member 141 is a guide rail, and the second guide member 142 is a slider; or the first guide member 141 is a guide shaft, and the second guide member 142 is a guide block, and the guide block is slidably connected to the guide shaft.

[0067] In other embodiments, a lifting mechanism may be further provided on the two side brackets 14, and the lifting mechanism is used to drive the lifting platform assembly 30 to lift and lower as a whole, so that the transport vehicle 100 can lift and lower the transport vehicle 200 twice, and the lifting height of the transport vehicle 100 can be increased.

[0068] The lifting mechanism can be a servo electric cylinder or a hydraulic cylinder. For example, two servo electric cylinders are provided on the opposite sides of the two side brackets 14. The driving ends of the servo electric cylinders are connected to the lifting platform assembly 30. The four servo electric cylinders cooperate to lift the lifting platform assembly 30.

[0069] In this embodiment, Figure 6 and Figure 7 As shown, Figure 6 It is a structural diagram of the lifting platform components in a stacked state. Figure 7 It is a structural schematic diagram of the lifting platform assembly in a separated state. The lifting platform assembly 30 includes a chassis 31, a vehicle loading plate 33 and a lifting mechanism 35.

[0070] The chassis 31 is disposed on the chassis 12, for example, the chassis 31 is stacked with the chassis 12 and can be connected by fasteners, etc. The vehicle loading plate 33 is stacked with the chassis 31, and the vehicle loading plate 33 is used to carry the transport vehicle 200, and the vehicle loading plate 33 can be stacked on the chassis 31 and in contact with the chassis 31. The lifting mechanism 35 is disposed between the chassis 31 and the vehicle loading plate 33, and the lifting mechanism 35 is used to drive the vehicle loading plate 33 away from the chassis 31, so that the vehicle loading plate 33 and the chassis 31 are changed from a state of stacking and contacting each other to a state of separation from each other, and is used to drive the vehicle loading plate 33 to move toward the chassis 31, so that the vehicle loading plate 33 and the chassis 31 are changed from a state of separation and contacting each other to a state of stacking and contacting each other.

[0071] The lifting mechanism 35 includes a first folding frame 351, a second folding frame 353 and a transmission mechanism 355. The first end of the first folding frame 351 is hinged to the chassis 31, and the second end of the first folding frame 352 is slidably supported on the vehicle loading plate 33. The first end of the second folding frame 353 is hinged to the vehicle loading plate 33, and the second end of the second folding frame 353 is slidably supported on the chassis 31, and the middle part of the first folding frame 351 and the middle part of the second folding frame 353 are hinged to each other. The transmission mechanism 355 is used to change the intersection angle between the first folding frame 351 and the second folding frame 353, which is the angle between the first folding frame 351 and the second folding frame 353 at the hinged joint, and the change of the intersection angle can drive the vehicle loading plate 33 to rise and fall relative to the chassis 31.

[0072] In this embodiment, the transmission mechanism 355 is a telescopic rod, one end of which is hinged to the first folding frame 351, and the other end of the telescopic rod is hinged to the second folding frame 353, and the angle between the first folding frame 351 and the second folding frame 353 is changed by telescoping.

[0073] The telescopic rod may be a hydraulic telescopic rod driven by hydraulic pressure, or a pneumatic telescopic rod driven by pneumatic pressure, and the present application does not impose any limitation on this.

[0074] In some embodiments, one end of the telescopic rod is hinged to the first folding frame 351 , and the other end of the telescopic rod is hinged to the chassis 31 ; or one end of the telescopic rod is hinged to the second folding frame 353 , and the other end of the telescopic rod is hinged to the vehicle loading plate 33 .

[0075] In other embodiments, the transmission mechanism 355 may also be a motor and a chain, and the motor drives the second end of the second folding frame 353 to slide on the chassis 31 through the chain, thereby changing the intersection angle to drive the vehicle loading plate 33 to rise and fall relative to the chassis 31. The transmission mechanism 355 may also be other transmission methods, which are not limited in this application.

[0076] The lifting mechanism 35 may be a group, and the group of lifting mechanisms 35 is disposed in the middle of the chassis 31 and the vehicle loading plate 33 to stably lift and lower the vehicle loading plate 33 .

[0077] The lifting platform assembly 30 may also include two sets of lifting mechanisms 35, a first support beam 352 is connected between the two sets of first folding frames 351, a second support beam 354 is connected between the two sets of second folding frames 353, the telescopic end of the telescopic rod is hinged to the first support beam 352, the driving end of the telescopic rod is hinged to the second support beam 354, and the telescopic rod changes the intersection angle between the two sets of first folding frames 351 and the second folding frames 353 at the same time by telescoping. The two sets of lifting mechanisms 35 are arranged at intervals along the spacing direction of the two side brackets 14, which can further improve the stability of the lifting vehicle carrier 33.

[0078] The first support beam 352, the second support beam 354 and the telescopic rod are arranged non-coplanarly to avoid locking of the first support beam 352, the second support beam 354 and the telescopic rod. For example, a hinge seat is provided on the first support beam 352, the telescopic end of the telescopic rod is hinged to the hinge seat, and the angle between the telescopic end of the telescopic rod and the hinge seat is not 180 degrees, so that the angle between the first folding frame 351 and the second folding frame 353 can be changed when the telescopic rod is extended or retracted.

[0079] In this embodiment, there are four groups of lifting mechanisms 35 , which are arranged in pairs along the spacing direction and are distributed in pairs at opposite ends of the vehicle loading plate 33 to further enhance the lifting stability of the vehicle loading plate 33 .

[0080] like Figure 8 and Fig. 9 As shown, Figure 8 for Figure 6 Schematic diagram of the lifting platform assembly from above. Fig. 9 for Figure 6A partial enlarged structural diagram of the lifting platform assembly. The chassis 31 includes a first frame 310 and two first sliding guides 312 respectively arranged on two opposite inner sides of the first frame 310, the vehicle loading plate 33 includes a second frame 330 and two second sliding guides 332 respectively arranged on two opposite inner sides of the second frame 330, the two outer sides of the second end of the first folding frame 351 are rotatably connected to the first sliding members 355, the two outer sides of the second end of the second folding frame 353 are rotatably connected to the second sliding members 356, the first sliding member 355 is slidably connected to the corresponding first sliding guide 312, the second sliding member 356 is slidably connected to the corresponding second sliding guide 332, and the second frame 330 can be overlapped and separated from the first frame 310.

[0081] In other words, when the intersection angle between the first folding frame 351 and the second folding frame 353 changes, the first sliding member 355 slides under the guidance of the first sliding guide member 312, and the second sliding member 356 slides under the guidance of the second sliding guide member 332, so that the vehicle loading plate 33 can be raised and lowered relative to the chassis 31 more smoothly.

[0082] like Fig.10 As shown, Fig.10 for Figure 8 The lifting platform assembly 30 further includes a bridge mechanism 37, which is disposed at the end of the vehicle loading plate 33 to form a transition bridge between the vehicle loading plate 33 and the parking space for the transport vehicle 200 to pass through.

[0083] The bridge mechanism 37 includes a rotating shaft 370 , a plurality of pedals 371 , a swinging member 372 and a push rod 373 .

[0084] The rotating shaft 370 is rotatably disposed on the vehicle loading plate 33. A plurality of pedals 371 are fixedly connected to the rotating shaft 370, and the pedals 371 are used to form a transition bridge between the vehicle loading plate 33 and the parking space for the transport vehicle 200 to pass through. The swing member 372 is fixedly connected to the rotating shaft 370, and the two ends of the push rod 373 are respectively hinged to the swing member 372 and the vehicle loading plate 33.

[0085] The push rod 373 drives the swing member 372 to swing around the axis of the rotating shaft 370, so as to drive the plurality of pedals 371 to swing around the axis of the rotating shaft 370, thereby causing the plurality of pedals 371 to rotate to overlap the parking space and be retracted from the parking space.

[0086] The push rod 373 may be a hydraulic push rod or a pneumatic push rod, and the push rod 373 itself can be extended and retracted to drive the swing member 372 to swing around the axis of the rotating shaft 370 .

[0087] Further, if Figure 6 and Fig.10As shown, a first optical coupler 381 is connected to the vehicle loading plate 33, and a sensing sheet 382 is fixed to the rotating shaft 370. When the sensing sheet 382 rotates with the rotating shaft 370 until it is sensed by the first optical coupler 381, the push rod 373 stops driving the swing member 372 to swing, and the multiple pedals 371 extend to be coplanar with the vehicle loading plate 33 and can be overlapped on the parking space.

[0088] A second optical coupler 383 and a third optical coupler 384 are also provided on the side of the loading plate 33 facing away from the chassis 31. The second optical coupler 383 is arranged at one end of the loading plate 33, and the second optical coupler 383 is used to detect whether the transport vehicle 200 drives out of the loading plate 33 and detects whether the transport vehicle 200 drives into the loading plate 33. The third optical coupler 384 is arranged along the diagonal line of the loading plate 33, and the third optical coupler 384 is used to detect whether the transport vehicle 200 is carried on the loading plate 33.

[0089] Specifically, the end of the vehicle loading plate 33 where the transport sub-trolley 200 enters and exits is provided with a second optical coupler 383, so that the transport sub-trolley 200 can be detected when entering and exiting the vehicle loading plate 33. The third optical coupler 384 is arranged along the diagonal line of the vehicle loading plate 33, and it can be understood that the detection light of the third optical coupler 384 is emitted along the diagonal line of the vehicle loading plate 33, so that the transport sub-trolley 200 can be detected by the third optical coupler 384 when it is carried on the vehicle loading plate 33.

[0090] like Figure 5 and Figure 6 As shown, the second guide members 142 are provided on both sides of the vehicle loading plate 33, and the second guide members 142 are slidably connected to the first guide members 141. Further, a wire encoder 385 is connected to the chassis 12, and a pull seat 386 is connected to the vehicle loading plate 33. The wire of the wire encoder 385 is connected to the pull seat 386. The wire encoder 385 is used to detect the lifting height of the vehicle loading plate 33 to prevent the height of the vehicle loading plate 33 from exceeding the height limit of the first guide member 141. At the same time, the height of the vehicle loading plate 33 relative to the chassis 31 can be detected in real time to ensure the accuracy of the lifting height of the vehicle loading plate 33.

[0091] The vehicle loading plate 33 is also provided with a positioning sensor 387, which is used to align the vehicle loading plate 33 with the parking space. In other words, the positioning sensor 387 detects whether the height of the vehicle loading plate 33 is aligned with the height of the parking space. If the height of the vehicle loading plate 33 is different from the height of the parking space, the height of the vehicle loading plate 33 is further adjusted. If the height of the vehicle loading plate 33 matches the height of the parking space, the multiple pedals 371 are adjusted to overlap the parking space, so as to facilitate the transport sub-carriage 200 to transport the vehicle between the parking space and the transport mother car 100, that is, the positioning sensor 387 is used to further ensure the alignment between the vehicle loading plate 33 and the parking space.

[0092] Combined with reference Figure 2 and Fig.11Two spaced-apart trolley guide rails 391 are provided on the side of the vehicle loading plate 33 facing away from the chassis 31, and trolley guide wheels 392 are provided on the side of the transport trolley 200 facing the vehicle loading plate 33. The trolley guide wheels 392 are used to roll with the trolley guide rails 391 and enter between the two trolley guide rails 391 to correct the running track of the transport trolley 200, thereby preventing the vehicle carried by the transport trolley 200 from colliding with the side frame 14.

[0093] Furthermore, a vehicle positioning member 393 is provided on the side of the vehicle loading plate 33 facing away from the chassis 31 , and a vehicle positioning seat 394 is provided on the side of the transport vehicle 200 facing the vehicle loading plate 33 . The vehicle positioning member 393 is used to sense the vehicle positioning seat 394 , thereby positioning the transport vehicle 200 .

[0094] Further, see Figure 5 , Figure 8 and Fig.11 The transport mother vehicle 100 further includes a battery 40, which is used for power supply. The battery 40 is provided in the side bracket 14, the chassis 12 is provided with a first charging connector 120, the battery 40 supplies power to the first charging connector 120, the vehicle loading plate 33 is provided with a second charging connector 331 facing the chassis 12, the vehicle loading plate 33 is provided with a sub-vehicle positioning member 393 on the side away from the chassis 31, and the sub-vehicle positioning member 393 can also be electrically connected to the second charging connector 331, and the transport sub-vehicle 200 is provided with a sub-vehicle positioning seat 394 on the side facing the vehicle loading plate 33, and the sub-vehicle positioning seat 394 is used to be electrically connected to the sub-vehicle positioning member 393, so that when the sub-vehicle positioning seat 394 is connected to the sub-vehicle positioning member 393, it can be determined that the transport sub-vehicle 200 is located at the set position on the transport mother vehicle 100, and the movement of the transport sub-vehicle 200 can be stopped.

[0095] Among them, when the loading plate 33 is stacked on the chassis 31, the second charging connector 331 is electrically connected to the first charging connector 120; under the guidance of the trolley guide rail 391, the trolley positioning seat 394 is electrically connected to the trolley positioning member 393, thereby determining the position of the trolley 200 and stopping the movement of the trolley 200.

[0096] like Figure 5 As shown, the transport vehicle 100 also includes a control system 50, which is used to control the travel of the traveling frame 10 and regulate the lifting and lowering of the lifting platform assembly 30. The above-mentioned distance detector 151, visual detector 152, laser radar positioning sensor 153, first optical coupler 381, second optical coupler 383 and third optical coupler 384, alignment sensor 387 and wire encoder 385 are all connected to the control system 50 for communication, and the control system 50 is also connected to the travel mechanism 20 and the lifting platform assembly 30 for communication. The control system 50 is used to receive the data collected by the above-mentioned components and perform data processing, and form the final processing results into control instructions to control the travel of the transport vehicle 100 and the lifting and lowering of the vehicle loading plate 33.

[0097] The transport vehicle 100 further includes a power source 60, which is used to provide power to the transmission mechanism 355 and the push rod 373. For example, if the transmission mechanism 355 is a hydraulic telescopic rod driven by hydraulic pressure and the push rod 373 is a hydraulic push rod, the power source 60 may be a hydraulic pump; or if the transmission mechanism 355 is a pneumatic telescopic rod driven by pneumatic pressure and the push rod 373 is a pneumatic push rod, the power source 60 may be a pneumatic pump. In other words, the power source 60 may provide the power required by the transmission mechanism 355 and the push rod 373.

[0098] The power source 60 may further include a first power source 61 and a second power source 62 , wherein the first power source 61 provides power to the transmission mechanism 355 , and the second power source 62 provides power to the push rod 373 .

[0099] The side bracket 14 is further formed with a accommodating space 145, and the battery 40, the control system 50 and the power source 60 are arranged in the accommodating space 145 of the side bracket 14, for example, the battery 40 and the control system 50 are arranged in the accommodating space 145 of the same side bracket 14, and the power source 60 is arranged in the accommodating space 145 of the other side bracket 14.

[0100] Furthermore, various electrical components, cables, etc. can be arranged in the accommodating space 145, so that the layout of various components of the transport vehicle 100 is reasonable and compact.

[0101] Different from the prior art, the present application discloses a transport masonry vehicle.
