[0002] With the development of transportation technology, the demand for flying vehicles such as cars has increased. Some vehicles are directly equipped with wings, and the vehicle as a whole travels on land or flies in the air. Some vehicles are equipped with a detachable flying body and a driving body, flying in the air through the flying body and traveling on land through the driving body.

[0003] In the related art vehicles, the flying object directly docks on the moving body or takes off directly from the moving body to separate and combine. Since the flying object needs to carry passengers or cargo, it is heavy; the way of directly docking the flying object on the moving body puts forward higher requirements on the carrying capacity of the moving body and the docking control of the flying object. Summary of the invention

[0004] The main purpose of this application is to propose a separation and combination mechanism to facilitate the separation or combination of a flying body and a traveling body.

[0005] To achieve the above-mentioned purpose, the separation and combination mechanism proposed in the present application includes a first connecting component and a second connecting component, the first connecting component is used to connect the traveling body, and at least a part of the first connecting component is used to move relative to the traveling body along a preset direction; the second connecting component is used to connect the traveling body, and at least a part of the second connecting component is used to move relative to the traveling body along the preset direction; the first connecting component and the second connecting component are also used to connect a flying body, respectively, and the flying body is used to be spaced apart from the traveling body along the preset direction; after the first connecting component drives the flying body to move a preset distance toward the traveling body, the second connecting component is used to connect the flying body and drive the flying body to move toward the traveling body.

[0006] The present application also proposes a traveling device, which includes a traveling body and the above-mentioned separation and combination mechanism.

[0007] The present application also proposes a vehicle, which includes a flying object and the above-mentioned traveling equipment.

[0008] The present application also proposes a separation and combination method, which is used to combine a flying body and a traveling body spaced apart in a preset direction, and the separation and combination method comprises the following steps:

[0009] The flying body is driven to move a preset distance toward or away from the traveling body by a first connecting component;

[0010] The flying body is connected via a first connecting assembly and driven to continue to move toward or away from the traveling body.

[0011] The technical solution of the present application is to set up a first connecting component and a second connecting component for moving relative to a traveling body along a preset direction. The separation and combination mechanism can move the flying body parked on the side along the preset direction to the traveling body, which is beneficial to the separation or combination of the flying body and the traveling body; after the first connecting component drives the flying body to move a preset distance toward the traveling body, the second connecting component is used to connect the flying body and drive the flying body to move toward the traveling body. The first connecting component and the second connecting component adopt a method of successively moving the flying body along the preset direction, which is beneficial to reducing the moving stroke of the first connecting component and the moving stroke of the second connecting component, thereby reducing the component cost of the separation and combination mechanism.

[0046] The present application proposes a vehicle to facilitate the separation or combination of a flying body and a traveling body.

[0047] Reference Figure 1 and Figure 2 In one embodiment of the present application, the vehicle includes a flying body 6000 and a driving device. The driving device is used to drive on the ground, and the flying body 6000 is used to fly in the air after being separated from the driving device. Among them, the flying body 6000 includes a load cabin 6100 and a landing gear 6200, the load cabin 6100 is used to carry passengers or for carrying cargo, and the landing gear 6200 is used to carry the load cabin 6100 on the ground. Among them, the landing gear 6200 can be configured to include a first frame 6210 and a second frame 6220 that are arranged at intervals along a preset direction; at least part of the first frame 6210 can be moved close to or away from the load cabin 6100, and at least part of the second frame 6220 can be moved close to or away from the load cabin 6100, so as to reduce the overall occupied space of the vehicle. For example, the first frame 6210 and the second frame 6220 can be configured as telescopic landing gears or foldable landing gears.

[0048] The traveling device includes a traveling body 5000 and a separation and combination mechanism. The traveling body 5000 can be set as a car of the type similar to a pickup truck. Of course, the traveling body 5000 can also be set as a car of the type similar to a trailer, and this embodiment is not limited to this. It can be understood that the landing gear 6200 can form a gap at the bottom of the load compartment 6100, and at least part of the traveling body 5000 is used to travel into the gap, for example, by automatic parking or manual parking, so that the above-mentioned separation and combination mechanism can move into the gap, thereby driving the flying body 6000 to move. In addition, communication devices can be respectively provided on the flying body 6000 and the traveling body 5000 to communicate and transmit data through a network. Of course, the communication device on the flying body 6000 and the communication device on the traveling body 5000 can also communicate with the server to receive data from the server or transmit data to the server.

[0049] Among them, refer to Figure 3 The separation and combination mechanism includes a first connection component 4100 and a second connection component 4200. The first connection component 4100 is used to connect the traveling body 5000, and at least a part of the first connection component 4100 is used to move relative to the traveling body 5000 along a preset direction, such as moving along the X direction in the figure. The second connection component 4200 is used to connect the traveling body 5000, and at least a part of the second connection component 4200 is used to move relative to the traveling body 5000 along a preset direction, such as moving along the X direction in the figure.

[0050] The first connection assembly 4100 and the second connection assembly 4200 are also used to connect the flying body 6000, respectively. The flying body 6000 is used to be spaced apart from the traveling body 5000 along the preset direction X, which can be understood as the flying body 6000 being parked beside the traveling body 5000. After the first connection assembly 4100 drives the flying body 6000 to move toward the traveling body 5000 by a preset distance, the second connection assembly 4200 is used to connect the flying body 6000 and drive the flying body 6000 to move toward the traveling body 5000; for example, referring to Figure 3 After the first connecting assembly 4100 drives the flying body 6000 to move rightward by a preset distance, the second connecting assembly 4200 takes over and drives the flying body 6000 to continue moving rightward. The first connecting assembly 4100 and the second connecting assembly 4200 use a method of successively moving the flying body 6000 along a preset direction, which is beneficial to reducing the moving stroke of the first connecting assembly 4100 and the moving stroke of the second connecting assembly 4200, thereby reducing the component cost of the separation and combination mechanism.

[0051] In some embodiments, the flying body 6000 has a first stroke that moves with the first connecting component 4100, and the flying body 6000 has a second stroke that moves with the second connecting component 4200. The first stroke and the second stroke are connected end to end or partially overlap in a preset direction, so that the first connecting component 4100 and the second connecting component 4200 can realize relay to drive the flying body 6000 to move toward the traveling body 5000, and the first connecting component 4100 and the second connecting component 4200 can be set with a relatively shorter stroke, thereby reducing the cost of components.

[0052] In some embodiments, reference Figure 4 , the moving part of the first connecting component 4100 can include a rod body 4110, and the first connecting component 4100 can also be configured to include a cylinder body 4120, and the rod body 4110 is sleeved in the cylinder body 4120 to provide a more precise transmission. For example, the first connecting component 4100 can be configured as an in-line servo electric cylinder, an electric telescopic rod, a cylinder, a hydraulic cylinder, etc. Of course, the first connecting component 4100 can also be configured as a transmission belt or rope assembly, and the flying body 6000 is connected through a movable belt or rope, and this embodiment does not limit this.

[0053] Reference Figure 4 , Figure 5, a rotating pin 4130 is provided on the moving part of the first connecting component 4100 (for example, the moving part can be set as the above-mentioned rod body 4110), and the extending direction of the rotating pin 4130 forms an angle with the preset direction X, for example, the rotating pin 4130 extends along the Y direction in the figure and is perpendicular to the rod body 4110. Of course, the rotating pin 4130 can also form an angle of 80 degrees, 60 degrees, 45 degrees, etc. with the preset direction X, and this embodiment is not limited to this. The moving part of the first connecting component 4100 is used to rotate around the preset direction X, for example, along the U direction in the figure. The rotating pin 4130 is used to rotate out of or rotate into the bottom recess of the flying body 6000, and the rotating pin 4130 is used to abut the side wall of the bottom recess along the preset direction, thereby realizing the connection between the first connecting component 4100 and the flying body 6000, and driving the flying body 6000 to move through the first connecting component 4100. In this embodiment, when the first connection assembly 4100 and the flying body 6000 do not need to be connected, for example, when the flying body 6000 is combined with the traveling body 5000, the rotating pin 4130 can be rotated to a position parallel to the bottom surface of the flying body 6000, for example, rotated to the XY plane in the figure, so as to reduce the distance between the first connection assembly 4100 and the flying body 6000, and reduce the overall height of the flying body 6000 after being combined with the traveling body 5000. In addition, the rotating pin 4130 rotates out of or into the bottom depression of the flying body 6000, and a larger activity space is provided by the bottom depression of the flying body 6000, which can reduce the relative position accuracy requirements of the rotating pin 4130 and the bottom depression, and reduce the risk of motion interference between the rotating pin 4130 and the bottom depression of the flying body 6000.

[0054] In some embodiments, reference Figure 4, the separation and combination mechanism also includes a first drive device 4310, and the moving part of the first connecting assembly 4100 (for example, the moving part can be set as the above-mentioned rod body 4110) is connected to the output shaft of the first driving device 4310 to move along the preset direction X. For example, a transmission structure is provided in the cylinder 4120, the input end of the transmission structure is connected to the output shaft of the first driving device 4310, and the output end of the transmission structure is connected to the rod body 4110. The transmission structure is arranged in the cylinder 4120, which is conducive to reducing the probability of dust accumulation. Among them, the first driving device 4310 can be set as a rotating motor, etc., and the first driving device then moves the moving part of the first connecting assembly 4100 along the preset direction X through a transmission structure such as a nut transmission structure, a screw nut structure, etc. At this time, the cylinder 4120 can also be set to be fixedly connected to the seat body of the first driving device 4310, for example, by bolt connection, plug-in, etc., so as to improve the connection stability. When the moving part of the first connecting assembly 4100 includes the rod body 4110, the rotating pin 4130 can be arranged on the rod body 4110, for example, the rotating pin 4130 and the rod body 4110 are integrally formed by a bending process, a casting process, etc., or the rotating pin 4130 is welded to the rod body 4110. Of course, the first driving device 4310 can also be set as a cylinder, a linear motor, etc., and connected to the moving part of the first connecting assembly 4100 through its linear motion output shaft, which is not limited in this embodiment.

[0055] In some embodiments, reference Figure 4 , Figure 6 , the first connecting assembly 4100 also includes a second driving device 4320, and the second driving device 4320 is used to rotate the moving part of the first connecting assembly 4100 around a preset direction X, for example, along the U direction in the figure. Among them, the second driving device 4320 can be configured as a rotary motor, and the second driving device 4320 can be configured to be connected to the seat body of the first driving device 4310, for example, by bolt connection, snap connection, etc. In addition, the second driving device 4320 is also used to drive the seat body of the first driving device 4310 and the moving part of the first connecting assembly 4100 to rotate around a preset direction, which can be understood as the second driving device 4320 drives the seat body of the first driving device 4310 and the moving part of the first connecting assembly 4100 to rotate along the U direction in the figure. Among them, the moving part of the first connecting component 4100, the base body of the first driving device 4310 and the second driving device 4320 can be arranged in sequence along the direction away from the flying body 6000, for example, in sequence along the preset direction X, so that the first connecting component 4100 can provide more installation space for other components beside the preset direction X.

[0056] In some embodiments, reference Figure 4The separation and combination mechanism further includes at least one bearing 4140, for example, two bearings 4140 are arranged at intervals along the preset direction X. The inner ring of the bearing 4140 is sleeved on the cylinder 4120, and the outer ring of the bearing 4140 is used to connect with the traveling body 5000. In this embodiment, the bearing 4140 can reduce the rotation resistance of the cylinder 4120 and reduce the power consumption of the second driving device 4320; the bearing 4140 can also support the first connecting assembly 4100, and improve the movement accuracy of the first connecting assembly 4100 driving the flying body 6000 to move along the preset direction.

[0057] In some embodiments, continue to refer to Figure 4 The separation and combination mechanism also includes a first guide rail 4150 and a first slider 4160. The first guide rail 4150 is extended along a preset direction X. The first guide rail 4150 is arranged on a moving part of the first connecting component 4100 for facing a side of the flying body 6000. For example, the first guide rail 4150 is arranged on the left side in the figure, so that the first connecting component 4100 can provide more installation space for other components beside the preset direction X.

[0058] In addition, the first slider 4160 is slidably connected to the first guide rail 4150, which can be understood as the first slider 4160 can slide along the preset direction X in the figure. The first guide rail 4150 is used to be fixedly connected to the traveling body 5000, for example, by bolt connection, slot connection, etc. The first slider 4160 is connected to the moving part of the first connecting assembly 4100, for example, connected to the above-mentioned rod body 4110; specifically, the first slider 4160 can be provided with a through hole, and the moving part of the first connecting assembly 4100 is sleeved in the through hole and can rotate around a preset direction; and the moving part of the first connecting assembly 4100 is limitedly connected to the first slider 4160 in the preset direction, for example, the rod body 4110 is provided with retaining rings on both sides of the first slider 4160 to limit the position in the preset direction. When the moving part of the first connecting assembly 4100 moves toward the flying body 6000, the first slider 4160 can support it, thereby improving the moving accuracy of the moving part of the first connecting assembly 4100. For example, when the rod body 4110 is extended toward the flying body 6000 relative to the cylinder body 4120, the first slider 4160 can support the rod body 4110, reduce the sagging amplitude of the rod body 4110, improve the position accuracy of the end of the rod body 4110, improve the position accuracy of the end of the rod body 4110 relative to the flying body 6000, and improve the connection efficiency between the first connecting component 4100 and the flying body 6000.

[0059] In some embodiments, reference Figure 7, the second connecting component 4200 includes a second guide rail 4210 and a second slider 4220. For example, the second connecting component 4200 can be set as a linear slide. The second guide rail 4210 is used to connect the traveling body 5000, for example, by bolt connection, slot connection, etc.; the second slider 4220 is used to connect the flying body 6000. The second guide rail 4210 is extended along the preset direction X, and the second slider 4220 is slidably connected to the second guide rail 4210, so that the second slider 4220 can move along the preset direction X in the figure. Of course, the second connecting component 4200 can also be set as an in-line servo electric cylinder, an electric telescopic rod, a cylinder, a hydraulic cylinder, etc.; or, the second connecting component 4200 can also be set as a transmission belt or rope assembly, and the flying body 6000 is connected by a movable belt or rope, which is not limited in this embodiment.

[0060] Reference Figure 7 The separation and combination mechanism further includes a third driving device 4330, which can be configured as a driving motor, etc. The third driving device 4330 is transmission-connected to the moving part of the second connecting assembly 4200, for example, it is transmission-connected to the second slider 4220 through a screw nut structure, etc.; the third driving device 4330 is used to move the moving part of the second connecting assembly 4200 along a preset direction X.

[0061] Reference Figure 7 , Figure 8 , the second slider 4220 is provided with a first locking structure 4230, and the first locking structure 4230 is used to detachably lock with the flying body 6000, so as to realize the connection between the second connecting assembly 4200 and the flying body 6000. Of course, the second connecting assembly 4200 and the flying body 6000 can also be connected by a bolt structure, a plug-in structure, etc. It can be understood that after the first connecting assembly 4100 drives the flying body to move a preset distance, for example, after moving to the right by a preset distance in the figure, the second connecting assembly 4200 can be connected to the flying body 6000 through the above-mentioned first locking structure 4230, so as to continue to drive the flying body 6000 to move along a preset direction X, for example, continue to move to the right in the figure. The manner in which the first locking structure 4230 is detachably locked with the flying body 6000 is conducive to improving the assembly and disassembly efficiency of the first locking structure 4230 and the flying body 6000.

[0062] In some embodiments, reference Figure 8 , Fig. 9The first locking structure 4230 includes a first connection notch 4231 and a first locking rod 4232. The first connection notch 4231 is used to face the connection pin 6700 of the flying body 6000, so that the first connection notch 4231 is convenient for the connection pin 6700 to enter. The first locking rod 4232 is used to move to the first connection notch 4231, and the first locking rod 4232 is used to abut against the side of the connection pin 6700 of the flying body 6000 that is away from the traveling body 5000, for example, to block Fig. 9 The left side of the middle connecting pin 6700. The first locking rod 4232 can be moved manually; the first locking rod 4232 can also be moved by an electric method such as a motor drive to improve the degree of automation.

[0063] In some embodiments, reference Fig. 9 The second guide rail 4210 is provided with a first positioning pin 4240 at one end thereof facing the flying body 6000. For example, the first positioning pin 4240 is provided at Fig. 9 The first positioning pin 4240 is used to extend into the positioning hole of the flying body 6000, so that after the first connecting assembly 4100 drives the flying body 6000 to move a preset distance toward the traveling body 5000 and before the second connecting assembly 4200 connects the flying body 6000 through the first locking structure 4230, the first positioning pin 4240 cooperates with the positioning hole to improve the position accuracy of the flying body 6000 relative to the second connecting assembly 4200, and improve the connection efficiency of the first locking structure 4230 connecting the flying body.

[0064] The first positioning pin 4240 and the positioning hole on the flying body 6000 are respectively extended along the preset direction X, and the end of the first positioning pin 4240 is provided with a first inclined wall surface 4241 or at least a portion of the inner wall of the positioning hole is inclined, thereby improving the efficiency of the first positioning pin 4240 extending into the positioning hole of the flying body 6000. In addition, at least a portion of the first inclined wall surface 4241 is arranged beside the preset direction X, for example, at least a portion of the first inclined wall surface 4241 is arranged in the Y direction in the figure; or, the positioning hole on the flying body 6000 is inclined at a portion of the inner wall beside the preset direction X, for example, the portion of the inner wall of the positioning hole in the Y direction in the figure is inclined. In this embodiment, the first positioning pin 4240 and the positioning hole on the flying body 6000 can more quickly achieve positioning on the side of the preset direction X, for example, more quickly achieve positioning in the Y direction in the figure, so that the connecting pin 6700 on the flying body 6000 can enter the first connecting notch 4231 more quickly, thereby improving the connection efficiency of the first locking structure 4230 connecting the flying body 6000.

[0065] In some embodiments, reference Fig.10The separation and combination mechanism also includes a second locking structure 4250. The second locking structure 4250 is arranged on the side of the second guide rail 4210 that is opposite to the flying body 6000. The second locking structure 4250 can be arranged to be fixedly connected to the traveling body 5000, for example, by welding, bolting, plugging, etc.; the second locking structure 4250 is used for detachable locking with the flying body 6000. In this embodiment, after the flying body 6000 is moved by the relay of the first connecting component 4100 and the second connecting component 4200, and the flying body 6000 is moved along the preset direction X to the combination position with the traveling body 5000, the flying body 6000 and the traveling body 5000 can be stably connected through the second locking structure 4250, thereby improving the stability of the flying body 6000 when being transported on the traveling body 5000. Refer to Fig.12 A plurality of second locking structures 4250 may be provided on the traveling body 5000 to further improve the stability of the flying body 6000 during transportation on the traveling body 5000 .

[0066] In some embodiments, the second locking structure 4250 includes a second connection notch and a second locking rod, and the second connection notch is used to face the connection pin of the flying body 6000, so that the second connection notch is convenient for the connection pin to enter. The second locking rod is used to move to the second connection notch and abut against the side of the connection pin of the flying body 6000 that is away from the traveling body 5000. The second locking rod can be moved manually; the second locking rod can also be moved by electric means such as motor drive to improve the degree of automation.

[0067] In some embodiments, reference Fig.11 The second guide rail 4210 is provided with a second positioning pin 4260 on the side facing away from the flying body 6000, and the second positioning pin 4260 is used to extend into the positioning hole of the flying body 6000; in this embodiment, after the flying body 6000 is relayed by the first connecting component 4100 and the second connecting component 4200 and the flying body 6000 is moved along the preset direction X to the combination position with the traveling body 5000, and before the flying body 6000 and the traveling body 5000 are connected through the above-mentioned second locking structure 4250, the second positioning pin 4260 cooperates with the positioning hole of the flying body 6000, thereby improving the relative position accuracy of the connecting pin of the flying body 6000 and the second connecting notch, and improving the efficiency of the connecting pin of the flying body 6000 entering the second connecting notch.

[0068] In some embodiments, the second positioning pin 4260 and the positioning hole on the flying body 6000 are respectively extended along the preset direction X, and the end of the second positioning pin 4260 is provided with a second inclined wall surface 4261 or at least a portion of the inner wall of the positioning hole is inclined, thereby improving the efficiency of the second positioning pin 4260 extending into the positioning hole of the flying body 6000. At least a portion of the second inclined wall surface 4261 is arranged beside the preset direction, or a portion of the inner wall of the positioning hole beside the preset direction is inclined. In this embodiment, the second positioning pin 4260 and the positioning hole on the flying body 6000 can more quickly achieve positioning beside the preset direction X, so that the connecting pin on the flying body 6000 can more quickly enter the second connecting notch, thereby improving the connection efficiency of the second locking structure 4250 connecting the flying body 6000.

[0069] In some embodiments, reference Fig.12 The separation and combination mechanism includes two second connection components 4200, which are used to be arranged along the bottom surface of the flying body 6000 and are respectively arranged on both sides of the first connection component 4100 along the preset direction X. The two second connection components 4200 can improve the moving stability of the flying body 6000 when driving the flying body 6000 to move. In some embodiments, the first connection component 4100 and the second connection component 4200 are used to be arranged at intervals along the bottom surface of the flying body 6000, thereby increasing the spacing between the two second connection components 4200 and further improving the moving stability of the flying body 6000. In addition, the interval between the first connection component 4100 and the second connection component 4200 can also accommodate other components, thereby improving the overall space utilization of the vehicle.

[0070] Reference Fig.12 One of the third driving device 4330 and the first locking structure 4230 is arranged on the side of the second connecting component 4200 away from the first connecting component 4100, and the other of the third driving device 4330 and the first locking structure 4230 is arranged on the side of the second connecting component 4200 facing the first connecting component 4100. The third driving device 4330 and the first locking structure 4230 are arranged relative to each other to further improve the overall space utilization of the vehicle.

[0071] Of course, in order to further improve the overall space utilization of the vehicle, at least one of the third driving device 4330 and the first locking structure 4230 can be arranged on the side of the second connecting component 4200 away from the first connecting component 4100; or, at least one of the third driving device 4330 and the first locking structure 4230 can be arranged on the side of the second connecting component 4200 facing the first connecting component 4100, and this embodiment does not impose any restrictions on this.

[0072] In some embodiments, reference Fig.12 The separation and combination mechanism further includes a guide structure 4400, which is extended along the preset direction X and is used to be arranged in the bottom interval of the flying body 6000. In this embodiment, when the first connecting assembly 4100 and the second connecting assembly 4200 drive the flying body 6000 to move along the preset direction X, the guide structure 4400 can reduce the yaw angle of the flying body 6000 and the traveling body 5000 along the preset direction X through the interaction with the bottom interval of the flying body 6000, and the flying body 6000 can be aligned relative to the traveling body 5000, thereby improving the centering accuracy of the flying body 6000 and the traveling body 5000.

[0073] Among them, refer to Fig.12 , two sets of guide rolling bodies 6600 can be provided at the bottom of the carrying cabin 6100, and the guide rolling bodies 6600 can be configured to include balls, rollers or wheels. The two sets of guide rolling bodies 6600 form a bottom interval extending along the preset direction X, and the bottom interval can be inserted into the guide structure 4400. In this embodiment, the two sets of guide rolling bodies 6600 can not only interact with the guide structure 4400 to guide, but also reduce friction by rolling, thereby improving the movement efficiency of the flying body 6000.

[0074] In some embodiments, reference Fig.12 The guide structure 4400 includes a first vertical plate 4410 and a second vertical plate 4420. The first vertical plate 4410 and the second vertical plate 4420 are respectively extended along the preset direction X. The first vertical plate 4410 and the second vertical plate 4420 are spaced apart from each other. At least part of the first connecting assembly 4100 is disposed in the space between the first vertical plate 4410 and the second vertical plate 4420, thereby improving the overall space utilization of the vehicle. The first connecting assembly 4100 and the second connecting assembly 4200 are used to be spaced apart along the bottom surface of the flying body 6000. The first vertical plate 4410 is disposed in the space between the first connecting assembly 4100 and one of the second connecting assemblies 4200. The second vertical plate 4420 is disposed in the space between the first connecting assembly 4100 and another of the second connecting assemblies 4200, thereby further improving the overall space utilization of the vehicle.

[0075] In some embodiments, the guide structure 4400 may be configured to include a guide end 4401 for facing the flying body 6000, and the width of the guide end 4401 decreases in the direction toward the flying body 6000, so as to more conveniently enter the bottom space of the flying body 6000. The first vertical plate 4410 is used to face one end of the flying body 6000 and the second vertical plate 4420 is used to face one end of the flying body 6000 to form the guide end 4401; specifically, the distance between the first vertical plate 4410 for facing one end of the flying body 6000 and the second vertical plate 4420 for facing one end of the flying body 6000 may be reduced in the direction toward the flying body 6000. For example, the first vertical plate 4410 is used to face one end of the flying body 6000 and is bent toward the second vertical plate 4420, and the second vertical plate 4420 is used to face one end of the flying body 6000 and is bent toward the first vertical plate 4410.

[0076] In some embodiments, reference Fig.12 The bottom of the load compartment 6100 is provided with a supporting rolling body 6500, which can be configured to include a ball, a roller or a roller, etc. The supporting rolling body 6500 is used to abut against the traveling body 5000, thereby improving the moving efficiency of the supporting rolling body 6500 on the traveling body 5000.

[0077] In some embodiments, reference Fig.13 The traveling body 5000 has a supporting surface 5210 for supporting the flying body 6000. The supporting surface 5210 is used to be inclined toward one end of the flying body 6000, for example, the left end in the figure. The inclined portion of the supporting surface 5210 is used to make the flying body 6000 move upward toward the flying body 6000, so that when the flying body 6000 moves toward the flying body 6000, the weight of the flying body 6000 is transferred to the traveling body 5000 to be carried, so as to make the landing gear 6200 of the flying body 6000 leave the ground or retract.

[0078] Among them, refer to Fig.14 , the traveling body 5000 includes a wheel set 5100 and a body structure 5200 that can be raised and lowered relative to the wheel set 5100, and the first connecting assembly 4100 and the second connecting assembly 4200 are respectively connected to the body structure 5200. Specifically, the relative lifting of the body structure 5200 and the wheel set 5100 can be achieved through lifting assemblies such as a suspension structure. Among them, the wheel set 5100 can be configured to include a plurality of wheel bodies, each of which can be lifted and lowered relative to the body structure 5200 through an independent suspension structure, so as to adjust the relative orientation accuracy between the first connecting assembly 4100 and the flying body 6000 and improve the connection efficiency. For example, in Fig.14In the figure, the distance H1 of the vehicle body structure 5200 relative to the wheel set 5100 can be changed to a distance H2 by relatively descending.

[0079] In this embodiment, in addition to the method of rotating to enter or exit, the above-mentioned rotating pin 4130 can also enter the bottom recess of the flying body 6000 by the rise of the vehicle body structure 5200 relative to the wheel group 5100, and the rotating pin 4130 can also exit the bottom recess of the flying body 6000 by the lowering of the vehicle body structure 5200 relative to the wheel group 5100, thereby improving the connection flexibility of the rotating pin 4130, the first connecting component 4100 and the flying body 6000.

[0080] In some embodiments, reference Fig.15 A traction ring 6300 is provided at the bottom of the carrying cabin 6100, and the inner space of the traction ring 6300 can form the bottom depression for the rotation pin 4130 to enter. The inner side wall of the traction ring 6300 is used to connect the moving part of the first connecting assembly 4100, for example, the inner side wall of the traction ring 6300 can be used for the rotation pin 4130 to abut against, thereby achieving the connection between the first connecting assembly 4100 and the flying body 6000.

[0081] In some embodiments, reference Fig.15 The traction ring 6300 includes a first traction end 6301 and a second traction end 6302 which are arranged relatively along a preset direction X, and the first traction end 6301 is used to face the traveling body 5000. When the flying body 6000 is moved toward the traveling body 5000, the first traction end 6301 can be used to connect with the first connecting assembly 4100, and can be specifically connected through the above-mentioned rotating pin 4130. The width of the first traction end 6301 decreases in the direction toward the traveling body 5000, so that after the rotating pin 4130 enters, the relative position accuracy of the flying body 6000 and the traveling body 5000 is improved through the mutual contact between the rotating pin 4130 and the first traction end 6301, and the centering accuracy is improved.

[0082] In addition, the second traction end 6302 is used to face away from the traveling body 5000; when the flying body 6000 is moved away from the traveling body 5000, the second traction end 6302 can be used to connect with the first connecting assembly 4100, and can be specifically connected through the above-mentioned rotating pin 4130. The width of the second traction end 6302 decreases in the direction away from the traveling body 5000, so that after the rotating pin 4130 enters, the rotating pin 4130 and the second traction end 6302 abut each other, so that the flying body 6000 maintains a certain position accuracy in the process of moving away from the traveling body 5000.

[0083] In some embodiments, reference Fig.15The inner side wall of the traction ring 6300 facing the traveling body 5000 is provided with a first traction recess 6303, and the first traction recess 6303 is used to accommodate part of the first connecting assembly 4100, such as connecting the rotating pin 4130, so as to improve the connection stability of the first connecting assembly 4100. The first traction recess 6303 can be provided on the first traction end 6301, so that the connecting part of the first connecting assembly 4100 (such as the rotating pin 4130) can enter the first traction recess 6303 more quickly.

[0084] In some embodiments, reference Fig.15 The inner side wall of the traction ring 6300 facing away from the traveling body 5000 is provided with a second traction recess 6304, and the second traction recess 6304 is used to accommodate part of the first connecting assembly 4100, such as connecting the rotating pin 4130, so as to improve the connection stability of the first connecting assembly 4100. The second traction recess 6304 can be provided on the second traction end 6302, so that the connecting part of the first connecting assembly 4100 (such as the rotating pin 4130) can enter the second traction recess 6304 more quickly.

[0085] In some embodiments, reference Fig.15 The flying body 6000 is also provided with a detection device 6400, which is used to detect the relative position between the moving part of the first connecting component 4100 (such as the rotating pin 4130) and the flying body 6000, so as to improve the relative position accuracy before the first connecting component 4100 and the flying body 6000 are connected, such as improving the relative position accuracy between the rotating pin 4130 and the traction ring 6300. The detection device 6400 can be set as a camera or other device.

[0086] This application also proposes a separation and combination method, referring to Fig.16 The separation and combination method is used to combine the flying body 6000 and the traveling body 5000 which are arranged at intervals along a preset direction X. The separation and combination method comprises the following steps:

[0087] The flying body 6000 is driven by the first connecting assembly 4100 to move a preset distance toward or away from the traveling body 5000;

[0088] The flying body 6000 is connected via the second connecting assembly 4200 and drives the flying body 6000 to continue to move toward or away from the traveling body 5000 .

[0089] For example, refer to Fig.16After the first connecting assembly 4100 drives the flying body 6000 to move rightward by a preset distance, the second connecting assembly 4200 takes over and drives the flying body 6000 to continue moving rightward. The first connecting assembly 4100 and the second connecting assembly 4200 use a method of successively moving the flying body 6000 along a preset direction, which is beneficial to reducing the moving stroke of the first connecting assembly 4100 and the moving stroke of the second connecting assembly 4200, and is beneficial to reducing the cost of parts.

[0090] Among them, refer to Figures 17 to 29 The flying body 6000 and the traveling body 5000 of the above-mentioned transportation vehicle can be combined by referring to the following steps of the separation and combination method.

[0091] Specifically, refer to Fig.17 , Fig.18 , the vehicle body structure 5200 can be raised relative to the wheel set 5100, and while the vehicle body structure 5200 supports part of the weight of the flying body 6000, the rotating pin 4130 can enter the bottom recess of the flying body 6000, specifically, the rotating pin 4130 can enter the traction ring 6300.

[0092] Reference Fig.19 , Fig. 20 , the moving part of the first connecting assembly 4100 can be moved toward the traveling body 5000, specifically, the rotating pin 4130 can be moved toward the traveling body 5000, so that the rotating pin 4130 abuts against the traction ring 6300. In addition, the flying body 6000 can retract the part of the landing gear 6200 toward the traveling body 5000, for example, retract the first frame 6210 and support the ground through the second frame 6220.

[0093] Reference Fig.21 , Fig. 22 The first connecting assembly 4100 drives the flying body 6000 to move a preset distance along a preset direction X, specifically, to the right in the figure. Specifically, the movement of the rotating pin 4130 can drive the traction ring 6300 and the flying body 6000 to move.

[0094] In addition, refer to Fig.23After the first connection component 4100 drives the flying body 6000 to move a preset distance along the preset direction X, the second connection component 4200 is positioned with the positioning hole of the flying body 6000 through the first positioning pin 4240, and the second connection component 4200 is detachably locked with the flying body 6000 through the first locking structure 4230. When two groups of second connection components 4200 are provided, the two first locking structures 4230 corresponding to the two groups of second connection components 4200 can be synchronously moved to be detachably locked with the flying body 6000 to reduce the movement control data of the first locking structure 4230; of course, the two first locking structures 4230 can also be asynchronously moved to be detachably locked with the flying body 6000 to improve the connection position accuracy of each first locking structure 4230 with the flying body 6000.

[0095] Reference Fig.24 , Fig.25 and Fig.26 After the second connecting assembly 4200 is detachably locked with the flying body 6000 through the first locking structure 4230, the rotating pin 4130 moves away from the traveling body 5000, for example, Fig.24 Move the position in Fig.25 The rotating pin 4130 is rotated to exit the bottom depression of the flying body 6000, for example, exit the above-mentioned traction ring 6300. After the second connecting assembly 4200 is detachably locked with the flying body 6000 through the first locking structure 4230, the rotating pin 4130 is again exited from the bottom depression of the flying body 6000, which is conducive to reducing the risk of accidental separation of the flying body 6000 when the first connecting assembly 4100 and the second connecting assembly 4200 are relayed.

[0096] Reference Fig. 27 , Fig.28 After the second connecting component 4200 moves the flying body 6000 toward the traveling body 5000 by another preset distance, for example, after the center of gravity of the flying body 6000 is moved to the traveling body 5000, the landing gear 6200 can be folded away from another part of the traveling body 5000, for example, the second frame 6220 mentioned above can be folded.

[0097] Reference Fig.29 After the landing gear 6200 is folded away from the other part of the traveling body 5000, the second connecting assembly 4200 moves the flying body 6000 toward the traveling body 5000 to the coupling position, and then fixes the flying body 6000 to the traveling body 5000; for example, first position the flying body 6000 through the positioning pin 4260 and the positioning hole of the flying body 6000, and then lock and fix the flying body 6000 to the traveling body 5000 through the second locking structure 4250.

[0098] It can be understood that since the present traveling equipment, vehicle and separation and combination method adopt all the technical solutions of all the embodiments of the above-mentioned separation and combination mechanism, they at least have all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0099] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
