The present application proposes a vehicle, referring to fig. 1 and 2, comprising a road vehicle 8000 and a device to be combined with the road vehicle 8000, wherein the device to be combined can be provided as an aircraft 9000. Road vehicle 8000 is intended to travel on the ground, and aircraft 9000 is intended to fly in the air after exiting road vehicle 8000. Among other things, the aircraft 9000 may be configured to include a stowage compartment 9100 for stowing an occupant or for stowing cargo, and a landing gear 9200 for stowing the stowage compartment 9100 on the ground. The landing gear 9200 may further include a first frame 9210 and a second frame 9220 for being spaced along the preset direction X; at least a portion of the first frame 9210 may be movable closer to or farther from the load compartment 9100 and at least a portion of the second frame 9220 may be movable closer to or farther from the load compartment 9100 in order to reduce the overall footprint of the vehicle. For example, the first frame 9210 and the second frame 9220 may be provided as telescopic landing gear and folding landing gear. Naturally, when a sufficient avoidance space is provided in the road vehicle 8000, the landing gear 9200 may be provided in a fixed landing gear structure, and this embodiment is not limited thereto.

The road vehicle 8000 may be configured as a pick-up-type vehicle, although the road vehicle 8000 may be configured as a trailer-type vehicle, and the present embodiment is not limited thereto. In addition, the road vehicle 8000 may include a separate coupling mechanism to separate or couple the aircraft 9000 waiting for the combined device and the road vehicle 8000 by the separate coupling mechanism.

The wheel set 8100 may include a plurality of wheel bodies, where each wheel body may implement a relative elevation with the vehicle body structure 8200 through an independent suspension structure, so as to adjust a relative azimuth precision of the connection assembly 7000 and the aircraft 9000, and improve a connection efficiency of the connection assembly 7000 and the aircraft 9000.

Of course, the aircraft 9000 may also rest directly on the road vehicle 8000 in a manner that is convenient to implement, or the aircraft 9000 may take off directly from the road vehicle 8000, which is not limited in this embodiment.

In the related art, after the aircraft 9000 and the road vehicle 8000 are integrated together, there is a case where the connection stability of the aircraft 9000 and the road vehicle 8000 needs to be further improved. In some embodiments, referring to fig. 3, 4, the vehicle further comprises a locking structure 8700, the locking structure 8700 comprising a first threaded bore 8771 provided on one of the road vehicle 8000 and the aerial vehicle 9000, the locking structure 8700 further comprising a rotational shaft 8710 provided on the other of the road vehicle 8000 and the aerial vehicle 9000; the shaft 8710 includes a first externally threaded section 8711, and the first externally threaded section 8711 is threadedly coupled to the first threaded bore 8771. The first external thread segment 8711 is driven to rotate into or out of the rotation shaft 8710 of the first threaded hole 8771, and may be driven to rotate by a manual rotation mode of a user or a driving device such as a motor. In this embodiment, when the vehicle 9000 is coupled in place in the road vehicle 8000, the detachable connection of the road vehicle 8000 and the vehicle 9000 to the fitting devices can be achieved by rotating the rotation shaft 8710 and screwing the first male screw portion 8711 to the first screw hole 8771, so that the connection stability of the vehicle 9000 to the road vehicle 8000 can be improved.

It will be appreciated that the road vehicle 8000 may also be removably secured to other devices to be secured to the road vehicle 8000 by the securing structure 8700, such as by securing the securing structure 8700 to a cargo box, a removable sleeping compartment, or some other devices to be secured. In the present application, a locking structure 8700 for detachably locking a road vehicle 8000 and a fitting device, such as an aircraft 9000, will be described. The structure of the aircraft 9000 can be applied to independent functional mechanisms such as cargo boxes and movable sleeping cabins under the condition of no contradiction.

In some embodiments, referring to fig. 5, 6 and 7, the locking structure 8700 further includes a first barrel 8720 and a cover assembly 8730; the cover assembly 8730 is connected to the axial end of the first barrel 8720, for example, by snap-fit connection, bolting, welding, etc.; the cover plate assembly 8730 is provided with a second threaded bore 8734; a portion of the rotating shaft 8710 is disposed in the first barrel 8720, a second external threaded section 8712 is disposed on the rotating shaft 8710, the second external threaded section 8712 is in threaded connection with the second threaded hole 8734, and at least a portion of the first external threaded section 8711 is disposed on a side of the cover assembly 8730 facing away from the first barrel 8720, which can be understood as the first external threaded section 8711 is closer to the first threaded hole 8771 than the second external threaded section 8712, such that the first external threaded section 8711 extends out relative to the first external threaded section 8711 when the first external threaded section 8711 is screwed into the first threaded hole 8771. It will be appreciated that at least a portion of the first externally threaded section 8711 may be retracted into the cap assembly 8730 and the first barrel 8720 as the first externally threaded section 8711 exits the first threaded bore 8771.

The first elastic member 8731 is configured to move the movable cover 8733 in the axial direction of the first cylinder 8720 to abut against the fixed cover 8732. In this embodiment, when the position deviation between the first external thread segment 8711 and the first threaded hole 8771 is large, for example, when the position deviation in the left-right direction of fig. 6 is large, the end of the first external thread segment 8711 may prop against another solid structure, the rotating shaft 8710 may receive a retraction force, and at this time, the movable cover 8733 provided with the second threaded hole 8734 may retract in time under the action of the first elastic member 8731, so that the risk of breakage of the rotating shaft 8710 due to stress deflection and excessive stress is reduced.

In some embodiments, referring to fig. 6, the locking structure 8700 further includes a second cover plate 8761, where the second cover plate 8761 is coupled to an end of the second barrel 8750 toward the cover plate assembly 8730, such as by welding, bolting, snap-fitting, or the like; the second cover 8761 is used for the conductive plate 8740 to abut, which can be understood that the rotating shaft 8710 drives the conductive plate 8740, so that the conductive plate 8740 abuts against the second cover 8761; the second cover plate 8761 is provided with a second through hole, and the rotating shaft 8710 passes through the second through hole, but the risk that the conductive plate 8740 is separated from the second cylinder 8750 can be reduced through the abutting between the second cover plate 8761 and the conductive plate 8740. It will be appreciated that to avoid the conductive disc 8740 from backing out of the second barrel 8750, the diameter of the second through-hole may be set smaller than the outer diameter of the conductive disc 8740.

In some embodiments, referring to fig. 6, the locking structure 8700 further includes a force measuring device 8762 (e.g., a force sensor) and a driving device 8763 (e.g., a driving motor) that are electrically connected, where the driving device 8763 is in driving connection with the second cylinder 8750, which can be understood that the driving device 8763 rotates the second cylinder 8750 in the circumferential direction of the first cylinder 8720 through the driving structure.

The force measuring device 8762 is disposed on a side of the second cover plate 8761 facing away from the second cylinder 8750, the second cover plate 8761 is used for abutting against the force measuring device 8762, and the force measuring device 8762 is used for detecting an abutting force of the second cover plate 8761, so as to be beneficial to avoiding damage to the rotating shaft 8710 caused by overlarge retraction force applied to the rotating shaft 8710. Wherein the driving means 8763 may be arranged to control its own power output in dependence of the electrical signal output by the force measuring means 8762 regarding the magnitude of the force. For example, when the force measuring device 8763 detects a large abutment force, the driving device 8763 stops the power output. For example, when the first external thread segment 8711 and the first threaded hole 8771 are screwed to the required degree, the first external thread segment 8711 drives the rotating shaft 8710, the conductive plate 8740 and the second cover plate 8761 to move, and the second cover plate 8761 abuts against the force measuring device 8762; at this time, the driving device 8763 may stop the power output or continue to provide the power output according to the magnitude relation between the force output value of the force measuring device 8762 and the preset value.
