Description

Technical Field

[0001] The present application relates to the field of transportation technology, and in particular to a road-going vehicle and its separation and combination mechanism, a vehicle and a separation and combination method. Background Art

[0002] With the development of transportation technology, flying cars have recently appeared. Flying cars have two functions: flying and driving. There are many forms of flying cars. One form of flying cars is to decouple driving and flying. Flying cars are composed of two parts, one is the road-driving body (also called road-driving vehicle), and the other is the aircraft. The road-driving body can be driven on the road alone like a car, and the aircraft can fly in the sky when needed. At the same time, the road-driving body can be combined with the aircraft to form an integrated flying car.

[0003] In the related technology, the aircraft takes off or lands directly on the road body, thereby separating or combining the road body and the aircraft. In this case, since the aircraft needs to carry passengers or cargo, it is heavy; the road body is required to have a very large carrying capacity, and the size of the part that carries the aircraft must be as large as possible to achieve safe landing; the positioning technology and docking control of the aircraft also require very precise positioning, making this technology of separating and combining the aircraft and the road body difficult to promote and apply in actual products. Summary of the invention

[0004] The main purpose of the present application is to provide a separation and combination mechanism for a road-going vehicle, so as to facilitate the separation or combination of a device to be combined and a road-going vehicle.

[0005] To achieve the above-mentioned purpose, the separation and combination mechanism of a road-going vehicle proposed in the present application is used to connect the road-going vehicle and the device to be combined with the road-going vehicle, and the separation and combination mechanism includes a connecting component, and the connecting component is used to connect the road-going vehicle, and at least part of the connecting component is used to move relative to the road-going vehicle along a preset direction; the connecting component is also used to connect the device to be combined, and the device to be combined is used to be arranged with the road-going vehicle at intervals along the preset direction; the device to be combined is provided with at least two first connecting structures arranged at intervals along the preset direction, and the connecting component is used to connect different first connecting structures to drive the device to be combined to move toward the road-going vehicle.

[0006] The present application also proposes a road-going vehicle, which comprises the above-mentioned separation and combination mechanism.

[0007] The present application also proposes a means of transportation, which comprises a device to be combined and the above-mentioned road-going vehicle.

[0008] The present application also proposes a separation and combination method, which is used to combine a road-going vehicle and a device to be combined that are spaced apart along a preset direction, wherein the device to be combined is provided with at least two first connection structures spaced apart along the preset direction, and the separation and combination method comprises the following steps:

[0009] The first connecting structure drives the device to be combined to move a preset distance toward or away from the traveling vehicle;

[0010] The device to be combined is driven by another of the first connecting structures to continue moving toward or away from the traveling vehicle.

[0011] The technical solution of the present application is to provide a connecting component for moving relative to a road-going vehicle along a preset direction. The separation and combination mechanism can move the aircraft and other devices to be combined that are parked on the side along the preset direction to the road-going vehicle, which is beneficial to the separation or combination of the aircraft and other devices to be combined and the road-going vehicle; after the connecting component is connected to the previous first connecting structure and drives the device to be combined to move toward the road-going vehicle a preset distance, the connecting component can be connected to the next first connecting structure and drive the device to be combined to continue moving toward the road-going vehicle until the device to be combined moves to the road-going vehicle; the connecting component can cooperate with different first connecting structures to move the aircraft and other devices to be combined toward the road-going vehicle in batches, which is beneficial to reducing the moving stroke of the connecting component and reducing the component cost of the separation and combination mechanism.

[0057] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. 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.

[0058] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0059] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0060] The present application proposes a transportation tool to facilitate the separation or combination of an aircraft and a road vehicle.

[0061] Reference Figure 1 and Figure 2 In one embodiment of the present application, the vehicle includes a road-going vehicle 8000 and a device to be combined with the road-going vehicle 8000, wherein the device to be combined can be configured as an aircraft 9000. The road-going vehicle 8000 is used to travel on the ground, and the aircraft 9000 is used to fly in the air after being separated from the road-going vehicle 8000. The aircraft 9000 can be configured to include a load cabin 9100 and a landing gear 9200, wherein the load cabin 9100 is used to carry passengers or cargo, and the landing gear 9200 is used to carry the load cabin 9100 on the ground.

[0062] The landing gear 9200 may also be configured to include a first frame 9210 and a second frame 9220 that are spaced apart along a preset direction X; at least a portion of the first frame 9210 may be moved closer to or away from the load compartment 9100, and at least a portion of the second frame 9220 may be moved closer to or away from the load compartment 9100, so as to reduce the overall occupied space of the vehicle. For example, the first frame 9210 and the second frame 9220 may be configured as a telescopic landing gear or a folding landing gear. Of course, when there is sufficient avoidance space on the road vehicle 8000, the landing gear 9200 may also be configured as a fixed landing gear structure, which is not limited in this embodiment.

[0063] In addition, the road vehicle 8000 includes the above-mentioned separation and combination mechanism. The road vehicle 8000 can be set as a car of the type similar to a pickup truck. Of course, the road vehicle 8000 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 9200 can form a gap at the bottom of the load compartment 9100, and at least part of the road vehicle 8000 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 be moved into the gap, thereby driving the aircraft 9000 to move. In addition, communication devices can be respectively set on the aircraft 9000 and the road vehicle 8000 to communicate and transmit data through a network. Of course, the communication device on the aircraft 9000 and the communication device on the road vehicle 8000 can also communicate with the server to receive data from the server or transmit data to the server.

[0064] Among them, refer to Figure 2 and Figure 3 The separation and combination mechanism includes a connection assembly 7000, which is used to connect the road vehicle 8000, for example, by bolt connection, welding, etc.; at least part of the connection assembly 7000 is used to move relative to the road vehicle 8000 along a preset direction X, and the connection assembly 7000 is also connected to the aircraft 9000, for example, by bolt connection, plug-in, clamping, etc. Wherein, the connection assembly 7000 may include a column servo electric cylinder, an electric telescopic rod, a cylinder, a hydraulic cylinder, etc. For example, in the separation state, the aircraft 9000 is used to be spaced apart from the road vehicle 8000 along the preset direction X, which can be understood as the aircraft 9000 being parked beside the road vehicle 8000. The connection assembly 7000 can move the aircraft 9000 onto the road vehicle 8000 and combine with the road vehicle 8000 through the part of itself that moves relative to the road vehicle 8000 along the preset direction X. Specifically, the aircraft 9000 is provided with at least two first connection structures 9300 spaced apart along a preset direction X, and the connection assembly 7000 is used to connect different first connection structures 9300 to drive the aircraft 9000 to move toward the road vehicle 8000. In some embodiments, referring to Figure 3 The aircraft 9000 is provided with three first connection structures 9300 spaced apart along a preset direction, so as to reduce the number of connections between the connection component 7000 and the first connection structure 9300 while shortening the moving stroke of the connection component 7000, which can be understood as reducing the number of round trips of the connection component 7000. Of course, the aircraft 9000 may also be provided with other numbers of first connection structures 9300 spaced apart along a preset direction, and this embodiment is not limited thereto.

[0065] In this embodiment, by providing a connecting assembly 7000 for moving relative to the road vehicle 8000 along a preset direction X, the separation and combination mechanism can move the aircraft 9000 and other devices to be combined parked on the side along the preset direction X to the road vehicle 8000, which is conducive to the separation or combination of the aircraft 9000 and other devices to be combined with the road vehicle 8000; after the connecting assembly 7000 is connected to the previous first connecting structure 9300 and drives the aircraft 9000 and other devices to be combined to move toward the road vehicle 8000 by a preset distance, the connecting assembly 7000 can be connected to the next first connecting structure 9300 and drive the aircraft 9000 to continue moving toward the road vehicle 8000 until the aircraft 9000 moves onto the road vehicle 8000; the connecting assembly 7000 can cooperate with different first connecting structures 9300 to move the aircraft 9000 and other devices to be combined toward the road vehicle 8000 in batches, which is conducive to reducing the moving stroke of the connecting assembly 7000 and reducing the component cost of the separation and combination mechanism.

[0066] In the above-mentioned means of transport, the road vehicle 8000 transfers the road vehicle 8000 and the device to be combined, the aircraft 9000, through the above-mentioned separation and combination mechanism. In addition, the road vehicle 8000 can also transfer other devices to be combined with the road vehicle 8000 through the separation and combination mechanism, for example, by transferring some devices to be combined, such as cargo boxes and movable sleeping cabins, through the separation and combination mechanism. In this application, the separation and combination mechanism between the road vehicle 8000 and the device to be combined, such as the aircraft 9000, will be taken as an example. In the absence of contradiction, the structure of the aircraft 9000 can be applied to independent functional mechanisms such as cargo boxes and movable sleeping cabins.

[0067] In some embodiments, reference Figure 3 , a second locking structure 8500 is provided on one of the road vehicle 8000 and the aircraft 9000, which can be understood as the locking structure 8500 connecting one of the road vehicle 8000 and the aircraft 9000, for example, by bolt connection, welding, etc. The second locking structure 8500 is used to be detachably locked with the other of the aircraft 9000 and the road vehicle 8000. For example, the second locking structure 8500 can lock the aircraft 9000 and the road vehicle 8000 after the aircraft 9000 is combined in place, so as to improve the stability of the aircraft 9000 when being transported on the road vehicle 8000. Among them, the locking structure 8500 can be connected to the road vehicle 8000 to reduce the load added to the aircraft 9000 by the weight of the locking structure 8500. Of course, the locking structure 8500 can also be connected to the aircraft 9000, and this embodiment is not limited to this.

[0068] In some embodiments, reference Figure 3 The road vehicle 8000 may be configured to include a wheel set 8100 and a body structure 8200 that can be lifted relative to the wheel set 8100, and the connection assembly 7000 is connected to the body structure 8200. Specifically, the relative lifting of the body structure 8200 and the wheel set 8100 may be achieved through a lifting assembly such as a suspension structure, so that the body structure 8200 drives the above-mentioned separation and combination mechanism to rise to abut against the aircraft 9000. Among them, the wheel set 8100 may be configured to include a plurality of wheel bodies, each of which may be lifted relative to the body structure 8200 through an independent suspension structure, so as to adjust the relative orientation accuracy of the connection assembly 7000 and the aircraft 9000, and improve the connection efficiency of the connection assembly 7000 and the aircraft 9000.

[0069] In some embodiments, reference Figure 3 The bottom of the carrying cabin 9100 may be provided with a supporting rolling body 9510, and the supporting rolling body 9510 may be configured to include a ball, a roller, or a roller, etc. The supporting rolling body 9510 is used to abut against the road vehicle 8000 so that the aircraft 9000 can slide on the road vehicle 8000.

[0070] In some embodiments, reference Figure 3 The separation and combination mechanism further includes a first driving device 7230, which is in transmission connection with the moving part of the connection assembly 7000, and is used to move the moving part of the connection assembly 7000 along a preset direction X; the first driving device 7230 is arranged on the moving part of the connection assembly 7000 to face the side of the road vehicle 8000, for example, on the right side in the figure. In this embodiment, the connection assembly 7000 can provide more installation space for other components beside the preset direction X, which is conducive to improving the overall structural compactness of the vehicle.

[0071] In some embodiments, reference Figure 3 , Figure 4, the moving part of the connecting assembly 7000 includes a connecting rod body, and the connecting assembly 7000 also includes a connecting cylinder 7310, and the connecting rod body is sleeved in the connecting cylinder 7310 to provide a more precise transmission. A transmission structure is arranged in the connecting cylinder 7310, and the input end of the transmission structure is connected to the output shaft of the first drive device 7230, and the output end of the transmission structure is connected to the connecting rod body. The transmission structure is arranged in the cylinder 7310, which is conducive to reducing the probability of dust accumulation and improving the service life, and reducing the overall volume of the connecting assembly 7000. For example, the connecting assembly 7000 can be set as an in-line servo electric cylinder, an electric telescopic rod, a cylinder, a hydraulic cylinder, etc. Of course, the connecting assembly 7000 can also be set as a transmission belt or a rope assembly, and the aircraft 9000 is connected through a movable belt or rope, and this embodiment does not limit this.

[0072] In some embodiments, reference Figure 3 , Figure 4 The separation and combination mechanism may further include a first guide rail 7210 and a first slider 7220. The first guide rail 7210 is extended along a preset direction X, and the first slider 7220 is slidably connected to the first guide rail 7210. The first guide rail 7210 is used to be fixedly connected to the road vehicle 8000, for example, by bolt connection, slot connection, etc. The first slider 7220 is connected to the moving part of the connecting assembly 7000, for example, connected to the above-mentioned connecting rod body; the first slider 7220 is provided with a first through hole, and the moving part of the connecting assembly 7000 passes through the first through hole, and the moving part of the connecting assembly 7000 is limitedly connected to the first slider 7220 in a preset direction, for example, the connecting rod body is provided with retaining rings on both sides of the first slider 7220 to limit the position in the preset direction X. In this embodiment, the first slider 7220 can move with the moving part of the connecting assembly 7000 (for example, the above-mentioned connecting rod body, etc.), so that the moving part of the connecting assembly 7000 bears radial force and improves the moving accuracy of the moving part of the connecting assembly 7000. For example, when the connecting rod body is extended toward the aircraft 9000 relative to the cylinder 7310, the first slider 7220 can support the connecting rod body, reduce the sagging amplitude of the connecting rod body, improve the position accuracy of the end of the connecting rod body, improve the position accuracy of the end of the connecting rod body relative to the aircraft 9000, and improve the connection efficiency between the connecting assembly 7000 and the aircraft 9000.

[0073] In some embodiments, reference Figure 3 The first guide rail 7210 is arranged on the moving part of the connecting assembly 7000 for facing the side of the aircraft 9000. For example, the first guide rail 7210 is arranged on the left side of the connecting rod body and the cylinder body 7310 in the figure, so that the connecting assembly 7000 can provide more installation space for other components beside the preset direction X.

[0074] In some embodiments, reference Figure 3 , Figure 5 The separation and combination mechanism also includes a guide structure 8300, which is connected to the road vehicle 8000; the guide structure 8300 is extended along the preset direction X, and the guide structure 8300 is used to be arranged in the bottom interval of the aircraft 9000. Among them, two groups of guide rolling bodies 9520 can be provided at the bottom of the load compartment 9100 to reduce the friction when interacting with the guide structure 8300 and improve the movement efficiency of the aircraft 9000. Among them, the guide rolling body 9520 can be configured to include a ball, a roller or a roller. The two groups of guide rolling bodies 9520 form a bottom interval extending along the preset direction to accommodate at least part of the guide structure 8300. In this embodiment, when the connecting assembly 7000 drives the aircraft 6000 to move along the preset direction X, the guide structure 8300 can interact with the bottom gap of the aircraft 9000, for example, by interacting with the above-mentioned two groups of guide rolling bodies 9520, so that the yaw angle of the aircraft 9000 and the road vehicle 8000 along the preset direction X is reduced, and the aircraft 9000 can be aligned relative to the road vehicle 8000, thereby improving the centering accuracy of the aircraft 9000 and the road vehicle 8000.

[0075] In some embodiments, the guide structure 8300 includes a first vertical plate 8310 and a second vertical plate 8320, and the first vertical plate 8310 and the second vertical plate 8320 are respectively extended along a preset direction X; the first vertical plate 8310 and the second vertical plate 8320 are spaced apart, and at least part of the connecting component 7000 is disposed in the space between the first vertical plate 8310 and the second vertical plate 8320, thereby improving the overall space utilization of the vehicle.

[0076] In some embodiments, the guide structure 8300 includes a guide end 8301 for facing the aircraft 9000, and the width of the guide end 8301 decreases in the direction toward the aircraft 9000, for example, decreases in the left direction in the figure, so that it can more conveniently enter the bottom space of the aircraft 9000. For example, the first vertical plate 8310 for facing one end of the aircraft 9000 and the second vertical plate 8320 for facing one end of the aircraft 9000 can form the guide end 8301; specifically, the spacing between the first vertical plate 8310 for facing one end of the aircraft 9000 and the second vertical plate 8320 for facing one end of the aircraft 9000 decreases in the direction toward the aircraft 9000, for example, decreases in the left direction in the figure. During manufacturing, the first vertical plate 8310 for facing one end of the aircraft 9000 can be bent toward the second vertical plate 8320, and the second vertical plate 8320 for facing one end of the aircraft 9000 can be bent toward the first vertical plate 8310. Of course, only the first vertical plate 8310 may be used to bend toward the second vertical plate 8320 toward one end of the aircraft 9000, or only the second vertical plate 8320 may be used to bend toward the first vertical plate 8310 toward one end of the aircraft 9000, and this embodiment does not impose any restrictions on this.

[0077] In some embodiments, reference Figure 5 The guide structure 8300 further includes a first cover plate 8330, which is extended along a preset direction X; one side of the first vertical plate 8310 and one side of the second vertical plate 8320 are respectively used to connect to the road vehicle 8000, for example, by welding, plugging or bolting. The other side of the first vertical plate 8310 and the other side of the second vertical plate 8320 are respectively connected to the first cover plate 8330, so that the risk of other components accidentally hitting the connection assembly 7000 is reduced through the first cover plate 8330, the transmission accuracy of the connection assembly 7000 is ensured, and the separation and combination efficiency of the aircraft 9000 and the road vehicle 8000 is improved.

[0078] In some embodiments, reference Figure 5The first cover plate 8330 is provided with a guide notch 8331 at one end thereof facing the aircraft 9000. The guide notch 8331 is used for the first connection structure 9300 to enter along a preset direction. The inner side wall of the guide notch 8331 is used to abut against the first connection structure 9300. The width direction of the guide notch 8331 is perpendicular to the preset direction. The width of the guide notch 8331 increases in the direction toward the aircraft 9000, for example, increases in the right direction in the figure. In this embodiment, when the connection assembly 7000 drives the aircraft 6000 to move along the preset direction X, the inner side wall of the guide notch 8331 can reduce the relative position deviation of the aircraft 9000 and the road vehicle 8000 along the width direction of the guide notch 8331 through interaction with the first connection structure 9300. The aircraft 9000 can be aligned relative to the road vehicle 8000, thereby improving the centering accuracy of the aircraft 9000 and the road vehicle 8000.

[0079] In some embodiments, the guide notch 8331 is provided with a guide slit 8332 on the side facing away from the aircraft 9000. For example, the guide slit 8332 is provided on the right side of the guide notch 8331 in the figure, and the guide slit 8332 is extended along the preset direction X. The guide slit 8332 is used for the first connection structure 9300 to enter along the preset direction, and the side wall of the guide slit 8332 is used to abut against the first connection structure 9300. After the relative position deviation is reduced by the guide notch 8331, the first connection structure 9300 can move stably along the preset direction X in the guide slit 8332, thereby improving the movement stability of the aircraft 9000.

[0080] In addition, the distance between one end of the first vertical plate 8310 facing the aircraft 9000 and the end of the second vertical plate 8320 facing the aircraft 9000 decreases in the direction toward the aircraft 9000, which can enable the first cover plate 8330 and the guide structure 8300 with the guide notch 8331 and the guide slit 8332 to have higher structural strength, thereby further improving the movement stability of the aircraft 9000.

[0081] In some embodiments, reference Figure 6 The first connecting structure 9300 is arranged on the carrying cabin 9100, and at least a part of the first connecting structure 9300 can move relative to the carrying cabin 9100 to be closer to or farther away from the carrying cabin 9100, so as to reduce the occupied space when the aircraft 9000 is combined with the road vehicle 8000, which is beneficial to reducing the overall volume of the vehicle and reducing the risk of movement interference between the aircraft 9000 and the road vehicle 8000.

[0082] Specifically, refer to Figure 6, the first first connection structure 9300 facing the road vehicle 8000 includes a fixed body 9321 and a moving body; for example, the first connection structure 9300 can be configured to include a connecting column 9310, and the connecting column 9310 is configured as the moving body. The fixed body 9321 is connected to the load compartment 9100, for example, by bolt connection, slot connection, etc., and the moving body is movably connected to the fixed body 9321 to move closer to or away from the load compartment 9100, for example, the moving body is configured as a telescopic pin, an electric push rod, a cylinder rod, etc.

[0083] In some embodiments, reference Figure 6 , the moving part of the connecting assembly 7000 is provided with a traction ring 7100; for example, the traction ring 7100 is connected to the above-mentioned connecting rod body by means of threaded connection, plug-in connection, etc. The traction ring 7100 is used to accommodate the first connecting structure 9300, for example, to accommodate the above-mentioned connecting column 9310, and the inner side wall of the traction ring 7100 is used to abut the first connecting structure 9300 along the preset direction X, so that the aircraft 9000 is driven to move along the preset direction X through the traction ring 7100. In this embodiment, the internal space of the traction ring 7100 is easy to be made relatively large, which can allow the first connecting structure 9300 to have a relatively large position error, which is conducive to improving the connection efficiency between the first connecting structure 9300 and the connecting assembly 7000.

[0084] When setting the traction ring 7100, refer to Figure 6 , a protrusion 9311 may be provided on the side of the connecting column 9310 away from the carrying cabin 9100, and the protrusion 9311 protrudes along the radial direction of the connecting column 9310, for example, the protrusion 9311 may be set in a ring shape, etc. Among them, at least part of the protrusion 9311 is set on the side of the preset direction X. In this embodiment, when the connecting column 9310 abuts against the inner side wall of the traction ring 7100 in the preset direction X, the part of the protrusion 9311 set on the side of the preset direction X can clamp the traction ring 7100, reducing the probability of the connecting column 9310 escaping from the traction ring 7100, and improving the connection stability between the aircraft 9000 and the connection assembly 7000. Further, the connecting column 9310 can be set to be thick at both ends and thin in the middle, so as to further improve the connection stability between the aircraft 9000 and the connection assembly 7000.

[0085] In some embodiments, reference Figure 6The traction ring 7100 includes a first traction portion 7110 for facing away from the road vehicle 8000. The first traction portion 7110 is used to abut against the side of the first connecting structure 9300 facing away from the road vehicle 8000. The width of the first traction portion 7110 decreases along the direction facing away from the road vehicle 8000, so that after the first connecting structure 9300 enters the traction ring 7100, the first traction portion 7110 and the first connecting structure 9300 (such as the above-mentioned connecting column 9310) are abutted against each other, thereby improving the relative position accuracy of the aircraft 9000 and the road vehicle 8000 and improving the centering accuracy.

[0086] In some embodiments, the inner side wall of the first traction portion 7110 is provided with a first traction recess 7111, and the first traction recess 7111 is used to accommodate at least part of the first connection structure 9300, for example, the connection column 9310, so as to improve the connection stability between the aircraft 9000 and the road vehicle 8000. When the connection column 9310 is accommodated in the first traction recess 7111, the protrusion 9311 can further reduce the probability of the connection column 9310 escaping from the traction ring 7100 by clamping the first traction recess 7111, and further improve the connection stability between the aircraft 9000 and the connection assembly 7000.

[0087] In some embodiments, the roughness of the inner wall of the first traction portion 7110 is less than the roughness of the outer wall of the first traction portion 7110 to reduce the friction between the first traction portion 7110 and the first connection structure 9300 and improve the service life of the first traction portion 7110 and the first connection structure 9300.

[0088] In some embodiments, the traction ring 7100 includes a second traction portion 7120 for facing the road vehicle 8000, and the second traction portion 7120 is used to abut the side of the first connecting structure 9300 facing the road vehicle 8000. The width of the second traction portion 7120 decreases in the direction toward the road vehicle 8000, so that after the first connecting structure 9300 enters the traction ring 7100, the relative position accuracy of the aircraft 9000 and the road vehicle 8000 is improved, and the centering accuracy is improved through the mutual abutment between the second traction portion 7120 and the first connecting structure 9300 (such as the above-mentioned connecting column 9310).

[0089] In some embodiments, the inner side wall of the second traction portion 7120 is provided with a second traction recess 7121, and the second traction recess 7121 is used to accommodate at least part of the first connection structure 9300, for example, to accommodate the above-mentioned connection column 9310, so as to improve the connection stability between the aircraft 9000 and the road vehicle 8000. When the connection column 9310 is accommodated in the second traction recess 7121, the above-mentioned protrusion 9311 can further reduce the probability of the connection column 9310 escaping from the traction ring 7100 by clamping the second traction recess 7121, and further improve the connection stability between the aircraft 9000 and the connection assembly 7000.

[0090] In some embodiments, the roughness of the inner wall of the second traction portion 7120 is less than the roughness of the outer wall of the second traction portion 7120 to reduce the friction between the second traction portion 7120 and the first connection structure 9300 and improve the service life of the second traction portion 7120 and the first connection structure 9300.

[0091] It can be understood that the above-mentioned first traction part 7110 and the first traction recess 7111 can cooperate with the first connection structure 9300 when the aircraft 9000 is coupled to the road vehicle 8000, and the above-mentioned second traction part 7120 and the second traction recess 7121 can cooperate with the first connection structure 9300 when the aircraft 9000 is detached from the road vehicle 8000.

[0092] In some embodiments, reference Figure 6 , the width direction of the traction ring 7100 is perpendicular to the preset direction X, and the width of the traction ring 7100 is less than or equal to the minimum distance between the end of the first vertical plate 8310 facing the aircraft 9000 and the end of the second vertical plate 8320 facing the aircraft 9000, so that the traction ring 7100 can move along the preset direction X into the first vertical plate 8310 and the second vertical plate 8320, thereby improving the space utilization rate and reducing the impact of the traction ring 7100 on the external parts. At the same time, the traction ring 7100 can drive the first connection structure 9300 (such as the above-mentioned connection column 9310, etc.) into the above-mentioned guide notch 8331 and guide gap 8332, and the aircraft 9000 is also combined in place. The protrusion 9311 on the connection column 9310 can be engaged with the guide notch 8331 and the guide gap 8332, thereby reducing the risk of the aircraft 9000 accidentally falling off the road vehicle 8000.

[0093] In some embodiments, reference Figure 6The aircraft 9000 is provided with a first detection device 9400, which is used to detect the relative position of the first first connection structure 9300 facing the road vehicle 8000 and the moving part of the connection assembly 7000, so as to improve the relative position accuracy of the moving part of the connection assembly 7000 before connecting with the aircraft 9000, for example, to improve the relative position accuracy of the connection column 9310 and the traction ring 7100. The first detection device 9400 can be set as a camera or other device.

[0094] The first detection device 9400 may be connected to the fixed body 9321 , for example, by bolt connection, tape bonding, or the like.

[0095] The present application also proposes a separation and combination method, which is used to combine a road vehicle 8000 and an aircraft 9000 spaced apart along a preset direction, wherein the aircraft 9000 is provided with at least two first connection structures 9300 spaced apart along the preset direction, and the separation and combination method comprises the following steps:

[0096] The aircraft 9000 is driven to move a preset distance toward or away from the road vehicle 8000 by a first connection structure 9300, for example, the first connection structure 9300 is connected by the connection assembly 7000;

[0097] The aircraft 9000 is driven to continue to move toward or away from the road vehicle 8000 by another first connection structure 9300 , for example, by connecting another first connection structure 9300 through the above-mentioned connection assembly 7000 .

[0098] For example, refer to Figure 3 , Figure 7 After the connecting component 7000 is connected to the previous first connecting structure 9300 and drives the aircraft 9000 to move a preset distance toward the road vehicle 8000, the connecting component 7000 can be connected to the next first connecting structure 9300 and drive the aircraft 9000 to continue moving toward the road vehicle 8000 until the aircraft 9000 moves onto the road vehicle 8000; the connecting component 7000 can cooperate with different first connecting structures 9300 to move the aircraft 9000 toward the road vehicle 8000 in batches, which is beneficial to reducing the moving stroke of the connecting component 7000 and reducing the component cost of the separation and combination mechanism.

[0099] Among them, refer to Figures 8 to 13 The above-mentioned aircraft 9000 and road vehicle 8000 can be combined by referring to the following steps of the separation and combination method.

[0100] Specifically, refer to Figure 8 , Fig. 9After part of the aircraft 9000 is moved to the road vehicle 8000 by the first first connecting structure 9300, when part of the weight of the aircraft 9000 is supported by the road vehicle 8000, the landing gear 9200 can be partially folded toward the road vehicle 8000, for example, the first frame 9210 can be folded and the ground can be supported by the second frame 9220.

[0101] Reference Fig.10 , driving the aircraft 9000 to continue to move onto the road vehicle 8000 through the next first connection structure 9300; specifically, it may include retracting the previous first connection structure 9300 and extending the next first connection structure 9300, for example, extending into the above-mentioned traction ring 7100.

[0102] Reference Fig.11 , Fig.12 After the center of gravity of the aircraft 9000 is moved to the road-going vehicle 8000, the other part of the landing gear 9200 away from the road-going vehicle 8000 can be retracted, for example, the second frame 9220 can be retracted.

[0103] Reference Fig.13 , the aircraft 9000 is combined in place through the subsequent first connecting structure 9300, and the aircraft 9000 is locked with the road vehicle 8000, for example, through the above-mentioned second locking structure 8500.

[0104] In some embodiments, reference Fig.14 , a first locking structure 8400 is provided on one of the road vehicle 8000 and the aircraft 9000, and the first locking structure 8400 is used to be detachably locked with the other of the aircraft 9000 and the road vehicle 8000. For example, the first locking structure 8400 is provided on the road vehicle 8000, or the first locking structure 8400 is provided on the aircraft 9000, and this embodiment is not limited thereto.

[0105] Sometimes, the locking efficiency of the aircraft 9000 and the road vehicle 8000 needs to be improved. Fig.14, the aircraft 9000 or the road vehicle 8000 is provided with a first connecting pin 9530; the first locking structure 8400 includes a first lock body 8410 and a first locking rod 8420, and the first lock body 8410 is provided with a first connecting notch 8411; wherein the first lock body 8410 can be connected to the road vehicle 8000, for example, by fasteners such as bolts, screws, rivets, etc. or by welding, etc., to reduce the load added to the aircraft 9000 by the weight of the first lock body 8410. Of course, the first lock body 8410 can also be connected to the aircraft 9000, and this embodiment is not limited to this. The first connecting notch 8411 is used for the first connecting pin 9530 to move in along a preset direction X, and the preset direction X can be the direction in which the aircraft 9000 is relatively close to the road vehicle 8000. It can be understood that the first connecting pin 9530 moves into the first connecting notch 8411 along the preset direction X with the aircraft 9000 or the vehicle 8000. The first locking rod 8420 is used to move to cover at least a portion of the first connection gap 8411 and to abut against the side wall of the first connection pin 9530, thereby preventing the first connection pin 9530 from moving out of the first connection gap 8411. The first locking rod 8420 can be driven by a driving device such as a motor or a cylinder, and the first locking rod 8420 can also be moved manually, which is not limited in this embodiment. The diameter of the first connection pin 9530 is smaller than the maximum width of the first connection gap 8411. For example, referring to Fig.14 The space formed by the first connection notch 8411 and the first locking rod 8420 is circular as a whole, and the diameter of the circle formed by the arrangement is greater than the diameter of the first connection pin 9530. Of course, the space formed by the first connection notch 8411 and the first locking rod 8420 can also be a triangle, a quadrilateral, a pentagon, etc. as a whole, in which case the diameter of the inscribed circle of the space formed by the arrangement can be greater than the diameter of the first connection pin 9530. During the movement of the aircraft 9000 relative to the road vehicle 8000, for example, when the aircraft 9000 needs to be combined with the road vehicle 8000, specifically before the aircraft 9000 is driven to move along the preset direction X by the above-mentioned connecting assembly 7000, the first locking structure 8400 can be used to lock the aircraft 9000 with the road vehicle 8000, so that the first connecting notch 8411 can at least connect with the first connecting pin 9530 through the maximum width, thereby offsetting at least part of the position deviation between the aircraft 9000 waiting for the locking device and the road vehicle 8000, and allowing the first connecting pin 9530 to have a larger position error, which is beneficial to improving the combination success rate between the aircraft 9000 and the road vehicle 8000, and improving the locking efficiency of the aircraft 9000 and the road vehicle 8000.

[0106] In some embodiments, the first locking structure 8400 further includes a second driving device 8430 and a transmission body 8440, and the transmission body 8440 can move relative to the first locking body 8410, and the movement may include rotation and translation, wherein the translation may be connected by a slide groove, etc.; it can be understood that the transmission body 8440 moves by the drive of the second driving device 8430. Among them, the second driving device 8430 can be set as a driving motor, a driving cylinder, etc., and this embodiment is not limited to this.

Of course, the second connection structure may also be provided as a convex structure such as a hexagonal head, and the force-applying member may be correspondingly provided as a wrench or the like, which is not limited in this embodiment. The second connection structure is provided on the exposed part of the transmission body 8440, so as to facilitate the manual movement of the first locking rod 8420 in the event of accidental damage of the second driving device 8430, thereby reducing the risk that the first locking structure 8400 cannot be locked or unlocked due to the inability of the first locking rod 8420 to move.

[0108] In some embodiments, reference Fig.15 , Fig.17 The transmission body 8440 includes a rotating part 8441, which is rotatably connected to the first lock body 8410, so that the rotating part 8441 reduces the occupied space (relative to the connecting rod mechanism, etc.); the axial end of the rotating part 8441 is exposed to the first lock body 8410, and the second connecting structure is arranged at the exposed axial end of the rotating part 8441; the outer peripheral wall of the rotating part 8441 is provided with a first toothed structure 8442, for example, the rotating part 8441 and the first toothed structure 8442 can be formed by setting a gear; the first lock body 8410 is provided with a second toothed structure 8463, and the first toothed structure 8442 is meshed with the second toothed structure 8463 for transmission.

[0113] In the related art, after the aircraft 9000 is coupled to the road vehicle 8000, the connection may sometimes be unstable. Fig. 22 , Fig.23, the second locking structure 8500 includes a second lock body 8510, a second locking rod 8520 and a controllable force structure. The second lock body 8510 can be connected to the road vehicle 8000, for example, by fasteners such as bolts, screws, rivets, or welding, so as to reduce the load added to the aircraft 9000 by the weight of the second lock body 8510. Of course, the second lock body 8510 can also be connected to the aircraft 9000, which is not limited in this embodiment. The second lock body 8510 is provided with a second connection gap 8511; the second connection gap 8511 is used for the second connection pin 9540 to move into along a preset direction X, and the preset direction X can be the direction in which the aircraft 9000 is relatively close to the road vehicle 8000. It can be understood that the second connection pin 9540 moves into the second connection gap 8511 along the preset direction X with the aircraft 9000 or the vehicle 8000, so that the moving process of the aircraft 9000 and the locking process can be smoothly connected. The second locking rod 8520 is used to move to cover at least part of the second connection gap 8511 and to abut against the side wall of the second connection pin 9540, so as to prevent the second connection pin 9540 from moving out of the second connection gap 8511. The second locking rod 8520 can be driven by a driving device such as a motor or a cylinder, the second locking rod 8520 can also be moved manually, and the second locking rod 8520 can also be pushed and moved by the second connection pin 9540 and other structures, which is not limited in this embodiment. The controllable force structure is used to connect the second locking rod 8520 and prevent the second locking rod 8520 from moving away from the second connection gap 8511, thereby preventing the second connection pin 9540 from moving out of the second connection gap 8511, thereby improving the connection stability after the aircraft 9000 is combined with the road vehicle 8000. In this embodiment, the controllable force-applying structure can be understood as a force-applying structure that can keep the second locking rod 8520 covering the second connection notch 8511 or keep the second locking rod 8520 away from the second connection notch 8511 according to an electrical signal, such as a motor, a cylinder, and necessary transmission structures. In addition, the controllable force-applying structure can be controllable when the second connection locking rod 8520 prevents the second locking rod 8520 from being away from the second connection notch 8511, which is conducive to improving the automation of the second locking structure 8500.

It can be understood that the second locking rod 8520 is rotationally connected to the second lock body 8510; the controllable force structure includes a third driving device 8530 and a transmission member 8540. The transmission member 8540 is transmission-connected to the third driving device 8530. The third driving device 8530 can be configured as a driving device that can keep the second locking rod 8520 covering the second connection gap 8511 or keep the second locking rod 8520 away from the second connection gap 8511 according to an electrical signal; the third driving device 8530 can be configured as a driving motor, a driving cylinder, etc. that can be controlled by an electrical signal. Fig.23 , Fig. 27 When the second locking rod 8520 covers the second connection notch 8511, the third driving device 8530 is used to move the transmission member 8540 to abut against the side of the second locking rod 8520 facing away from the second connection notch 8511; it can be understood that the transmission member 8540 is moved by the driving of the third driving device 8530. The movement of the transmission member 8540 includes rotation and translation. For example, the transmission member 8540 is connected to the second lock body 8510 through a rotating shaft structure or a sliding groove structure to achieve rotation or translation. In this embodiment, when the second connecting pin 9540 shakes, the transmission member 8540 can prevent the force of the second connecting pin 9540 from directly acting on the third driving device 8530. It can be understood that the force of the second connecting pin 9540 first acts on the transmission member 8540 and then acts on the third driving device 8530, which is conducive to improving the service life of the third driving device 8530.

[0115] In some embodiments, the transmission member 8540 is rotatably connected to the second lock body 8510, for example, by a rotating shaft. Fig. 22 The third driving device 8530 is used to make the transmission member 8540 rotate along the first annular direction W1 or the second annular direction, and the first annular direction W1 is opposite to the second annular direction; for example, the first annular direction W1 is clockwise and the second annular direction is counterclockwise. Fig. 22 , Fig. 27When the second locking rod 8520 covers the second connecting notch 8511, the transmission member 8540 is used to rotate along the first annular direction W1 to abut the side of the second locking rod 8520 facing away from the second connecting notch 8511, for example, abutting the lower side of the second locking rod 8520 in the figure; a blocking block 8550 is provided on the second lock body 8510, and the blocking block 8550 can be set on the second lock body 8510 by welding, plugging, integral molding, etc.; the blocking block 8550 is used to abut the transmission member 8540 in front of the first annular direction W1, for example, abutting the transmission member 8540 on the left side in the figure, so as to prevent the second locking rod 8520 from driving the transmission member 8540 to rotate along the first annular direction W1. It can be understood that when the second connecting pin 9540 shakes, it will hit the second locking rod 8520, and the second locking rod 8520 has a tendency to move away from the second connecting notch 8511, thereby having a tendency to drive the transmission member 8540 to continue rotating along the first annular direction W1, and the blocking block 8550 limits this tendency. That is, in this embodiment, when the second connecting pin 9540 has a tendency to escape outward, the blocking block 8550 can block the transmission member 8540, thereby blocking the second locking rod 8520 through the transmission member 8540, so that the second locking rod 8520 stably locks the second connecting pin 9540.

[0116] In some embodiments, reference Fig.25 The second locking structure 8500 further includes a second detection device 8560, for example, the second detection device 8560 can be configured to include a third travel switch. The second detection device 8560 is electrically connected to the third driving device 8530, and the second detection device 8560 is used to detect that the second locking rod 8520 rotates to cover the second connection gap 8511, which can be understood as the second detection device 8560 outputs a detection signal when the second locking rod 8520 rotates to cover the second connection gap 8511; or, the second detection device 8560 is used to detect that the second connecting pin 9540 moves into the second connection gap 8511, which can be understood as the second detection device 8560 outputs a detection signal when the second connecting pin 9540 moves into the second connection gap 8511; thus, when the second connecting pin 9540 is in the locking position, the third driving device 8530 stops power output, thereby reducing the power consumption of the third driving device 8530.

[0117] In some embodiments, reference Fig.24, the second locking rod 8520, the transmission member 8540 and the second detection device 8560 are arranged on the same surface of the second lock body 8510, for example, on the upper surface in the figure; the third driving device 8530 is arranged on the other surface of the second lock body 8510 facing away from the transmission member 8540, for example, on the upper surface in the figure, thereby improving the space utilization of the second locking structure 8500. Among them, the second lock body 8510 can be set as a plate to facilitate the distribution of the second locking rod 8520, the transmission member 8540, the second detection device 8560 and the third driving device 8530.

[0118] In some embodiments, reference Fig.23 , an arcuate surface 8541 is provided on the side of the transmission member 8540 facing the second locking rod 8520. When the transmission member 8540 rotates to a preset position along the second circumferential direction, for example, when it rotates counterclockwise to the position in the figure, it can be understood as the position corresponding to the opening of the second locking rod 8520; at this time, the center of the arcuate surface 8541 is consistent with the rotation center of the second locking rod 8520 and the radius of the arcuate surface 8541 is greater than or equal to the maximum rotation radius R of the side of the second locking rod 8520 facing the transmission member 8540, so that the second locking rod 8520 can be smoothly opened and avoid hitting the transmission member 8540, while the transmission member 8540 can be set closer to the locking rod 8520 through the arcuate surface 8541, thereby improving the structural compactness of the locking structure 8500; in addition, when the transmission member 8540 abuts against the second locking rod 8520, the force arm of the transmission member 8540 is reduced, thereby improving the abutment stability of the transmission member 8540 against the second locking rod 8520.

[0119] In some embodiments, reference Fig.25 , Fig.26 and Fig. 27, one end of the second locking rod 8520 is rotatably connected to the second lock body 8510, and the other end of the second locking rod 8520 is provided with a third connection notch 8521; the second locking structure 8500 further includes a first elastic member 8570, the two ends of the first elastic member 8570 are respectively connected to the second lock body 8510 and the second locking rod 8520, and the first elastic member 8570 is used to rotate the second locking rod 8520 away from the second connection notch 8511 and away from the third connection notch 8521 for the second connecting pin 9540 to enter; it can be understood that when the second locking rod 8520 rotates away from the second connection notch 8511 to reach the stop position, the third connection notch 8521 is at least partially unblocked, and the second connecting pin 9540 can enter the third connection notch 8521. Among them, the first elastic member 8570 can be set as a spring, a shrapnel, etc. The inner side wall of the third connection gap 8521 is used for the second connection pin 9540 to abut against along the preset direction X, so as to drive the second locking rod 8520 to rotate to cover at least a portion of the second connection gap 8511. It can be understood that in order to enable the second connection pin 9540 to move from the third connection gap 8521 to the second connection gap 8511, during the rotation stroke of the second locking rod 8520, the third connection gap 8521 is connected to the second connection gap 8511; in addition, at the end of the rotation stroke of the second locking rod 8520, the second locking rod 8520 covers the second connection gap 8511 to prevent the second connection pin 9540 from coming out. In this embodiment, when the second connecting pin 9540 enters the second connecting notch 8511 along the preset direction X, it can store energy for the first elastic member 8570, so that the first elastic member 8570 can provide a power source for the second locking rod 8520. When the second locking rod 8520 needs to be opened, the first elastic member 8570 can provide at least part of the power for the second locking rod 8520, thereby reducing the power consumption of the second locking structure 8500.

[0120] In some embodiments, when the second locking structure 8500 is locked with the second connecting pin 9540, the inner side wall of the second connecting notch 8511 and the second locking rod 8520 respectively abut against the second connecting pin 9540, which can be understood as follows: the inscribed circle of the space enclosed by the second connecting notch 8511 and the second locking rod 8520 is consistent with the diameter of the second connecting pin 9540. In this embodiment, the inner side wall of the second connecting notch 8511 and the second locking rod 8520 respectively abut against the second connecting pin 9540, which is conducive to improving the connection stability of the road vehicle 8000 and the aircraft 9000 to be combined after locking.

[0121] Among them, refer to Fig.25 , Fig.26A first buffer layer 8512 may be provided on the inner side wall of the second connection notch 8511, and the first buffer layer 8512 may be set to rubber or the like to reduce the risk of the second connection pin 9540 hitting the second connection notch 8511; the first buffer layer 8512 may be attached to the side wall surface of the second connection notch 8511 by gluing, hot melting or the like. A second buffer layer 8522 may be provided on the inner side wall of the third connection notch 8521, and the second buffer layer 8522 may be set to rubber or the like to reduce the risk of the second connection pin 9540 hitting the third connection notch 8521; the second buffer layer 8522 may be attached to the side wall surface of the third connection notch 8521 by gluing, hot melting or the like. When the first buffer layer 8512 and the second buffer layer 8522 are set at the same time, when the second locking structure 8500 is locked with the second connecting pin 9540, the first buffer layer 8512 and the second buffer layer 8522 respectively abut against the second connecting pin 9540, thereby not only improving the connection stability of the road vehicle 8000 and the aircraft 9000 to be combined after locking through the first buffer layer 8512 and the second buffer layer 8522, but also reducing the risk of the second connecting pin 9540 hitting the first connecting notch 8511 or the second connecting notch 8521.

[0122] In the related art, sometimes the smoothness of the centering between the aircraft 9000 and the road vehicle 8000 needs to be improved.

A connection hole is provided on the first connection block 8650. A portion of the third cylinder 8630 is arranged in the connection hole, for example, by interference fit; another portion of the third cylinder 8630 extends out of the connection hole and is used to abut against the other of the road vehicle 8000 or the aircraft 9000, so as to improve the connection stability between the aircraft 9000 and the road vehicle 8000 by improving the flatness of the extended portion of the third cylinder 8630.

The positioning pin 8640 and the base plate 8661 are spaced apart, and the axial end of the third cylinder 8630 is used to move to abut the connecting plate 8662, thereby improving the connection stability between the aircraft 9000 and the road vehicle 8000; the spacing between the positioning pin 8640 and the base plate 8661 is used to accommodate part of the third cylinder 8630 and part of the first connecting block 8650, thereby improving the space utilization of the elastic limiting mechanism 8600.

[0126] In some embodiments, the surface of the base plate 8661 facing the positioning pin 8640 abuts against the first connection block 8650 to further improve the connection stability between the aircraft 9000 and the road vehicle 8000 .

[0127] In some embodiments, reference Fig.28The positioning pin 8640 and the first cylinder 8610 are respectively extended along the preset direction X, and the end of the positioning pin 8640 is provided with a first inclined wall surface 8641. For example, the first inclined wall surface 8641 can be formed by setting a chamfer or a fillet at the end of the positioning pin 8640, that is, the first inclined wall surface 8641 can include a plane or an arc surface; or, at least part of the inner side wall of the first cylinder 8610 is inclined, which is conducive to further improving the smoothness of the positioning pin 8640 entering the first cylinder 8610.

[0128] In some embodiments, reference Fig.28 At least part of the first inclined wall 8641 is arranged on the side of the preset direction X, or part of the inner wall of the first cylinder 8610 on the side of the preset direction X is inclined, so that the positioning accuracy of the aircraft 9000 and the road vehicle 8000 on the side of the preset direction X is improved through the interaction between the positioning pin 8640 and the first cylinder 8610.

[0129] In the related art, sometimes the connection stability between the aircraft 9000 and the road vehicle 8000 needs to be further improved. Fig.31 , Fig.32 The vehicle further comprises a third locking structure 8700, the third locking structure 8700 comprises a first threaded hole 8771 provided on one of the road vehicle 8000 and the aircraft 9000, and the third locking structure 8700 further comprises a rotating shaft 8710 provided on the other of the road vehicle 8000 and the aircraft 9000; the rotating shaft 8710 comprises a first external thread segment 8711, and the first external thread segment 8711 is threadedly connected with the first threaded hole 8771. The rotating shaft 8710 that drives the first external thread segment 8711 to be screwed into or out of the first threaded hole 8771 may be manually rotated by a user, or may be driven to rotate by a driving device such as a motor, and this embodiment is not limited thereto. In this embodiment, after the aircraft 9000 is combined with the road vehicle 8000, the rotating shaft 8710 can be rotated and the first external thread section 8711 can be threadedly connected with the first threaded hole 8771, thereby realizing a detachable connection between the road vehicle 8000 and the aircraft 9000 to be combined, thereby improving the connection stability between the aircraft 9000 and the road vehicle 8000.

[0130] In some embodiments, reference Fig.33 , Fig.34 and Fig.35The third locking structure 8700 also includes a fourth cylinder 8720 and a cover assembly 8730; the cover assembly 8730 is connected to the axial end of the fourth cylinder 8720, for example, by snap connection, bolt connection, welding, etc.; the cover assembly 8730 is provided with a second threaded hole 8734; part of the rotating shaft 8710 is arranged in the fourth cylinder 8720, and the rotating shaft 8710 is provided with a second external thread segment 8712, and the second external thread segment 8712 is threadedly connected with the second threaded hole 8734, and at least part of the first external thread segment 8711 is used to be arranged on the side of the cover assembly 8730 facing away from the fourth cylinder 8720. It can be understood that the first external thread segment 8711 is closer to the first threaded hole 8771 than the second external thread segment 8712, so that the first external thread segment 8711 is relatively extended outward when the first external thread segment 8711 is screwed with the first threaded hole 8771. It can be understood that when the first external thread segment 8711 withdraws from the first threaded hole 8771, at least a portion of the first external thread segment 8711 can also be retracted into the whole of the cover plate assembly 8730 and the fourth cylinder 8720. Among them, the first external thread segment 8711 and the second external thread segment 8712 can be integrally formed by thread processing, casting, etc.; the first external thread segment 8711 and the second external thread segment 8712 can be arranged to be connected, and the first external thread segment 8711 and the second external thread segment 8712 can also be arranged to be spaced, which is not limited in this embodiment. In this embodiment, the second external thread segment 8712 is threadedly connected to the first threaded hole 8771, and the rotating shaft 8710 can extend outward after rotation, for example, extend in the upward direction in the figure and move steadily toward the first external threaded hole 8711, thereby improving the process stability of the threaded connection between the first external thread segment 8711 and the first threaded hole 8771.

[0131] In some embodiments, reference Fig.34 , Fig.35The cover plate assembly 8730 includes a second elastic member 8731 and a stacked fixed cover plate 8732 and a movable cover plate 8733. The fixed cover plate 8732 is fixedly connected to the axial end of the fourth cylinder 8720, for example, by bolt connection, welding, snap connection, etc. The second threaded hole 8734 is provided on the movable cover plate 8733 and penetrates the movable cover plate 8733.

The second elastic member 8731 can be set as a spring, a spring, etc. One end of the second elastic member 8731 is connected to the movable cover plate 8733, for example, by welding, abutment, plug-in, etc. The other end of the second elastic member 8731 is connected to the fourth cylinder 8720 or the fixed cover plate 8732, including indirect connection or direct connection through other components. The second elastic member 8731 is used to move the movable cover plate 8733 along the axial direction of the fourth cylinder 8720 to abut against the fixed cover plate 8732. Fig.34 When the position deviation in the left and right directions is large, the end of the first external threaded section 8711 will hit other physical structures, and the rotating shaft 8710 will be subjected to a retraction force. At this time, the movable cover plate 8733 provided with a second threaded hole 8734 can retract in time under the action of the second elastic member 8731, thereby reducing the risk of the rotating shaft 8710 breaking due to skewed force or excessive force.

[0132] In some embodiments, reference Fig.34 The fixed cover plate 8732 is provided with a receiving groove 8735; at least part of the movable cover plate 8733 is received in the receiving groove 8735 to improve space utilization. The receiving groove 8735 can be formed by a stamping process, a casting process or a machining process. The inner side wall of the receiving groove 8735 is used to abut the movable cover plate 8733 along the circumference of the second threaded hole 8734 to circumferentially limit the movable cover plate 8733 to reduce the risk of the movable cover plate 8733 slipping. Fig.35 , the movable cover plate 8733 can be set as a rounded rectangular structure, and the receiving groove 8735 can be set as a rounded rectangular groove. Fig.36 , the movable cover 8733 can be set to a triangle, a pentagon, an ellipse or the like; refer to Fig.37 , Fig.38 The accommodating groove 8735 can also be correspondingly set to a triangle, a pentagon, an ellipse or the like, which is not limited in this embodiment.

In this embodiment, when the rotating shaft 8710 is retracted under force, it can be aligned with the first threaded hole 8771 through the smaller diameter position on the second inclined wall surface 8713, which is conducive to improving the centering efficiency of the first external thread segment 8711 and the first threaded hole 8771.

[0134] In some embodiments, reference Fig.34 , Fig.37 and Fig.38 The third locking structure 8700 also includes a conduction disk 8740 and a fifth cylinder 8750. The fifth cylinder 8750 is sleeved in the fourth cylinder 8720. The fifth cylinder 8750 can be coaxially arranged with the fourth cylinder 8720. The fifth cylinder 8750 is used to rotate along the circumferential direction of the fourth cylinder 8720, including a manual drive by a user and a drive method such as a motor; a conduction groove 8751 is provided on the inner side wall of the fifth cylinder 8750, and the conduction groove 8751 extends from one axial end to the other axial end of the fifth cylinder 8750, including an inclined setting and a vertical setting of the conduction groove 8751 relative to the axial end face of the fifth cylinder 8750. The conducting disc 8740 is disposed in the fifth cylinder 8750, and a conducting protrusion 8741 is disposed on the outer peripheral wall of the conducting disc 8740, and the conducting protrusion 8741 is slidably connected to the conducting groove 8751 along the extension direction of the conducting groove 8751, and the rotating shaft 8710 is fixedly connected to the conducting disc 8740, for example, by welding, plugging, etc.; wherein the rotating shaft 8710 can be coaxially arranged with the conducting disc 8740. In this embodiment, the fifth cylinder 8750 can not only drive the rotating shaft 8710 to rotate, but also allow the rotating shaft 8710 to move in the axial direction and retract, thereby reducing the risk of the rotating shaft 8710 being broken due to deflection of force or excessive force.

[0135] In some embodiments, the inner side wall of the fifth cylinder 8750 is provided with a plurality of conduction grooves 8751, and the conduction grooves 8751 are arranged along the circumference of the fifth cylinder 8750; the outer peripheral wall of the conduction disk 8740 is provided with a plurality of conduction protrusions 8741, and the conduction protrusions 8741 are connected to the conduction grooves 8751 in a one-to-one correspondence, thereby further improving the transmission stability of the fifth cylinder 8750 and the rotating shaft 8710. Among them, the conduction disk 8740 can be set as a gear; of course, the conduction disk 8740 can also be set as a triangle, rectangle, pentagon and other structures, which are not limited in this embodiment. Correspondingly, the cross section of the internal space of the fifth cylinder 8750 can be set to a star shape, triangle, rectangle, pentagon and the like.

[0136] In some embodiments, reference Fig.34 The third locking structure 8700 further includes a second cover plate 8761, which is connected to one end of the fifth cylinder 8750 facing the cover plate assembly 8730, for example, by welding, bolt connection, snap connection, etc. The second cover plate 8761 is used for the conductive disk 8740 to abut against, which can be understood as the shaft 8710 driving the conductive disk 8740, so that the conductive disk 8740 abuts against the second cover plate 8761; the second cover plate 8761 is provided with a fourth through hole, and the shaft 8710 passes through the fourth through hole, but can still pass through the abutment between the second cover plate 8761 and the conductive disk 8740, thereby reducing the risk of the conductive disk 8740 falling out of the fifth cylinder 8750. It can be understood that in order to prevent the conductive disk 8740 from falling out of the second cylinder 8750, the diameter of the fourth through hole can be set to be smaller than the outer diameter of the conductive disk 8740.

[0137] In some embodiments, reference Fig.34The third locking structure 8700 further includes an electrically connected force measuring device 8762 (e.g., a force measuring sensor) and a fourth driving device 8763 (e.g., a driving motor). The fourth driving device 8763 is in transmission connection with the fifth cylinder 8750. It can be understood that the fourth driving device 8763 causes the fifth cylinder 8750 to rotate along the circumferential direction of the fourth cylinder 8720 through the transmission structure. The force measuring device 8762 is arranged in the fourth cylinder 8720 and is fixedly connected to the fourth cylinder 8720, for example, by bolt connection, snap connection, etc., so as to facilitate the disassembly and assembly of the force measuring device 8762. The force measuring device 8762 is arranged on the side of the second cover plate 8761 facing away from the fifth cylinder 8750. The second cover plate 8761 is used to abut the force measuring device 8762. The force measuring device 8762 is used to detect the abutting force of the second cover plate 8761, which is conducive to preventing the shaft 8710 from being damaged by excessive retraction force. The driving device 8763 can be configured to control its own power output according to the electrical signal about the force output by the force measuring device 8762. 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 tightened to the required degree, the first external thread segment 8711 will drive the rotating shaft 8710, the conductive disk 8740, and the second cover plate 8761 to move, and the second cover plate 8761 abuts the force measuring device 8762; at this time, the fourth driving device 8763 can stop the power output or continue to provide the power output according to the size relationship between the force output value of the force measuring device 8762 and the preset value.

[0138] In some embodiments, reference Fig.34 , Fig.37 The third locking structure 8700 further includes a third elastic member 8764, which can be configured as a disc spring, a spring, a spring sheet, etc. The third elastic member 8764 is disposed in the fifth cylinder 8750, and the third elastic member 8764 is disposed on the side of the conductive disk 8740 facing away from the rotating shaft 8710; one end of the third elastic member 8764 is connected to the fifth cylinder 8750, for example, the third elastic member 8764 can be connected to the fifth cylinder 8750 by being clamped in a groove, etc.; the other end of the third elastic member 8764 is used to abut against the conductive disk 8740 to move the conductive disk 8740 toward the second cover plate 8761; for example, when the conductive disk 8740 moves excessively in the downward direction in the figure, the third elastic member 8764 abuts against the conductive disk 8740. In this embodiment, the third elastic member 8764 can provide a buffer when the rotating shaft 8710 and the conductive disk 8740 retract excessively, thereby preventing the rotating shaft 8710 and the conductive disk 8740 from damaging other components or themselves.

[0139] In some embodiments, reference Fig.34The third locking structure 8700 further includes a bearing 8765; the inner ring of the bearing 8765 abuts against the outer peripheral wall of the fifth cylinder 8750, and the outer ring of the bearing 8765 abuts against the inner peripheral wall of the fourth cylinder 8720, thereby realizing radial limiting; the bearing 8765 is fixedly connected to one of the fourth cylinder 8720 and the fifth cylinder 8750 along the axial direction, for example, by means of interference fit; the bearing 8765 is movably connected to the other of the fourth cylinder 8720 and the fifth cylinder 8750 along the axial direction. When the first external thread section 8711 is tightened with the first threaded hole 8771, the fifth cylinder 8750 has a tendency to abut against the force measuring device 8762; the bearing 8765 not only alleviates this tendency, but also ensures the radial position of the fifth cylinder 8750, thereby improving the running stability of the third locking structure 8700.

[0140] In some embodiments, reference Fig.40 , Fig.41 and Fig.42 The third locking structure 8700 further includes a second connecting block 8770 and an active groove 8780 provided on the road vehicle 8000 or the aircraft 9000. The second connecting block 8770 is provided in the active groove 8780, and the first threaded hole 8771 is provided on the second connecting block 8770. The bottom wall of the active groove 8780 faces the rotating shaft 8710 to prevent the second connecting block 8770 from falling out of the active groove 8780 in the direction toward the rotating shaft 8710. The bottom wall of the active groove 8780 is provided with a fifth through hole 8783. The fifth through hole 8783 is used for the first external thread segment 8711 to pass through; the movable groove 8780 is provided with a first limiting structure and a second limiting structure, the first limiting structure is used to abut the second connection block 8770 along the radial direction of the first threaded hole 8771 to reduce the risk of the second connection block 8770 slipping along the circumferential rotation; the second limiting structure is used to abut the side of the bottom wall of the second connection block 8770 facing away from the movable groove 8780 to reduce the risk of the second connection block 8770 being pushed away from the movable groove 8780 by the rotating shaft 8710. The second connection block 8770 is arranged in the movable groove 8780 and can move, for example, the second inclined wall surface 8713 of the rotating shaft 8710 abuts the first threaded hole 8771 to move the second connection block 8770; it is beneficial for the first threaded hole 8771 on the second connection block 8770 to move to a position more aligned with the first external thread segment 8711, and it is beneficial for the first external thread segment 8711 and the first threaded hole 8771 to improve the connection efficiency.

[0141] The first limiting structure includes two side walls of the movable groove 8780 that are arranged opposite to each other. Fig.41The first limiting structure includes a first baffle 8791 and a second baffle 8792 spaced apart along the extending direction of the movable groove 8780, and the second connecting block 8770 is disposed in the interval between the first baffle 8791 and the second baffle 8792. Of course, the first limiting structure may also include two side walls of the movable groove 8780 that are oppositely disposed and the first baffle 8791 and the second baffle 8792, which is not limited in this embodiment.

[0142] In some embodiments, reference Fig.41 One end of the first baffle plate 8791 is bent and fixedly connected to the bottom wall of the movable groove 8780. At this time, the first baffle plate 8791 can be set to an L-shape as a whole; one end of the second baffle plate 8792 is bent and fixedly connected to the bottom wall of the movable groove 8780. At this time, the second baffle plate 8792 can be set to an L-shape as a whole to respectively improve the connection stability of the first baffle plate 8791, the second baffle plate 8792 and the movable groove 8780, wherein the first baffle plate 8791, the second baffle plate 8792 and the movable groove 8780 can be connected by bolt connection, welding, etc.

[0143] In some embodiments, reference Fig.40 , Fig.42 The second limiting structure includes a first transverse plate 8781 and a second transverse plate 8782 which are arranged at intervals. The extension direction of the first transverse plate 8781 and the second transverse plate 8782 are respectively consistent with the extension direction of the movable groove 8780. The first transverse plate 8781 and the second transverse plate 8782 are respectively connected to the two side walls of the movable groove 8780. The movable groove 8780, the first transverse plate 8781 and the second transverse plate 8782 can be integrally formed by bending sheet metal. Of course, the movable groove 8780 and the first transverse plate 8781 and the second transverse plate 8782 can also be connected by welding or the like. The interval between the first transverse plate 8781 and the second transverse plate 8782 is respectively arranged opposite to the bending part of the first baffle 8791 and the bending part of the second baffle 8792. The interval between the first transverse plate 8781 and the second transverse plate 8782 improves the installation convenience of the first baffle 8791 and the second baffle 8792; it can be understood that the interval between the first transverse plate 8781 and the second transverse plate 8782 can facilitate tools such as screwdrivers and welding guns to enter the movable groove 8780 and align with the bent part of the first baffle 8791 and the bent part of the second baffle 8792, so as to perform bolt connection, welding and other operations on the first baffle 8791, the second baffle 8792 and the movable groove 8780.

[0144] In some embodiments, the fourth driving device 8763 connected to the fifth cylinder 8750 can be configured to include a driving motor and a reducer, and the reducer can be a gear reducer.
