Description

[0001] This application claims the priority of the Chinese patent application with the application number 202510644325.1 and the invention title "Tilting Rotor Deployment and Folding Mechanism and Flying Car" filed on May 19, 2025, the entire content of which is incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of flying cars, and particularly to a tilting rotor deployment and folding mechanism for a flying car and a flying car. Background Art

[0003] In recent years, with the technological development of future transportation and low-altitude economy, the concept of flying cars has emerged. Flying cars can achieve seamless connection of personnel and cargo transfer between the air and the ground. Their application scenarios are extensive, including air taxis to relieve urban traffic congestion, police air law enforcement, emergency rescue, low-altitude logistics, and tourism sightseeing, etc.

[0004] In order to generate the lift required for flight, a flying car needs to have a relatively long fixed wing. At the same time, in order to meet the requirement of vertical takeoff and landing of the flying car, tilting rotors also need to be provided on the fixed wing.

[0005] Among them, in order to meet the requirements of road driving, a flying car must maintain the same external dimensions as a traditional car. Therefore, how to achieve the folding and storage of the tilting rotors of the flying car has become an urgent problem to be solved. Summary of the Invention

[0006] In view of this, this application provides a tilting rotor deployment and folding mechanism for a flying car and a flying car, which can achieve the storage of the tilting rotors and reduce the extra space occupied by the tilting rotors.

[0007] Specifically, the following technical solutions are included:

[0008] In a first aspect, this application provides a tilting rotor deployment and folding mechanism for a flying car, and the tilting rotor deployment and folding mechanism includes a wing body plate, a fixed wing, a tilting rotor, and a switching and locking assembly;

[0009] There are two fixed wings, two tilting rotors, and two switching and locking assemblies. The two fixed wings are symmetrically arranged with respect to the YOZ plane and are respectively connected to the wing body plate, and the two tilting rotors are symmetrically arranged with respect to the YOZ plane;

[0010] The tilting rotor includes a rotating arm rod and at least two rotating wings. The at least two rotating wings are respectively installed at both ends of the rotating arm rod, and the rotating arm rod is rotatably installed on the fixed wing through the switching and locking assembly around a rotation axis;

[0011] The tilt-rotor is configured to be able to switch between an unfolded position and a folded position. In the unfolded position, the extending direction of the boom is perpendicular to the extending direction of the fixed wing; in the folded position, the extending direction of the boom is parallel to the extending direction of the fixed wing.

[0012] In a possible implementation, the tilt-rotor further includes a cantilever seat, the cantilever seat is fixed on the boom and protrudes outward relative to the side wall of the boom, and a disc lock piece protrudes from the cantilever seat;

[0013] The switching and locking assembly has a Y-direction lock groove and an X-direction lock groove arranged at intervals. When the disc lock piece cooperates with the Y-direction lock groove, the tilt-rotor is in the unfolded position; when the disc lock piece cooperates with the X-direction lock groove, the tilt-rotor is in the folded position.

[0014] In a possible implementation, in each tilt-rotor, there are two disc lock pieces, and the two disc lock pieces are symmetrically arranged along a direction perpendicular to the rotation axis;

[0015] In each switching and locking assembly, there are two Y-direction lock grooves and two X-direction lock grooves respectively, and the two Y-direction lock grooves and the two X-direction lock grooves are symmetrically arranged with the rotation axis as the center of symmetry respectively.

[0016] In a possible implementation, the switching and locking assembly includes a lock sleeve, a Y-direction lock catch, an X-direction lock catch and a locking and unlocking structure;

[0017] One end of the lock sleeve is fixed to the fixed wing;

[0018] The Y-direction lock catch and the X-direction lock catch are both fixed on the inner wall of the lock sleeve, and the Y-direction lock catch and the X-direction lock catch are distributed along the circumferential direction of the lock sleeve;

[0019] The Y-direction lock catch includes a Y-direction upper lock catch and a Y-direction lower lock catch connected together, and the Y-direction upper lock catch and the Y-direction lower lock catch form the Y-direction lock groove;

[0020] The X-direction lock catch includes an X-direction upper lock catch and an X-direction lower lock catch connected together, and the X-direction upper lock catch and the X-direction lower lock catch form the X-direction lock groove;

[0021] The locking and unlocking structure at least partially extends between the Y-direction lock catch and the X-direction lock catch. The locking and unlocking structure is used for circumferentially limiting the disc lock piece in the Y-direction lock groove and the X-direction lock groove. The locking and unlocking structure is slidably connected with the lock sleeve, and the locking and unlocking structure can move relative to the lock sleeve along the extending direction of the rotation axis.

[0022] In a possible implementation, the locking and unlocking structure includes a slider, a bridging arm, and an elastic member;

[0023] The slider is located between the Y-direction lock and the X-direction lock, the bridging arm is connected to the slider and the elastic member respectively, the end of the elastic member facing away from the bridging arm is in contact with the fixed wing, and the elastic member can generate elastic deformation along the extension direction of the rotation axis.

[0024] In a possible implementation, the linear dimensions of the Y-direction locking groove and the X-direction locking groove in the extension direction of the rotation axis are both adapted to the thickness of the disc locking plate.

[0025] In one possible implementation, the position height of the X-direction lock groove in the extension direction of the rotation axis is higher than the position height of the Y-direction lock groove in the extension direction of the rotation axis, so that the Y-direction lock groove and the X-direction lock groove are staggered in the extension direction of the rotation axis.

[0026] In a possible implementation, a difference in position height between the X-direction locking groove and the Y-direction locking groove in the extending direction of the rotation axis is greater than or equal to a thickness of the disc locking plate.

[0027] In a possible implementation, a limiting sliding groove is recessed on the inner wall of the locking sleeve, the slider cooperates with the limiting sliding groove, and the limiting sliding groove is used to limit the movement path and extreme position of the slider.

[0028] In a second aspect, the present application provides a flying car, comprising the tilt-rotor unfolding and folding mechanism provided by any embodiment of the first aspect.

[0029] The beneficial effects of the technical solution provided by the embodiments of the present application include at least the following: since the swing arm is rotatably connected to the fixed wing through the switching locking assembly, and the tilt-rotor can be switched between the deployed position and the folded position, therefore, by locking the tilt-rotor in the folded position, the extension direction of the swing arm is parallel to the extension direction of the fixed wing, which can fully utilize the space occupied by the fixed wing in its own extension direction, reduce the additional space occupied by the tilt-rotor, and realize the storage of the tilt-rotor, so that the rotating wing will not cause harm to passers-by when the flying car is driving on conventional roads.

Detailed Description of the Embodiment

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the protection scope of the present application.

[0049] For the directional terms involved in the embodiments of the present application, such as "upper", "lower", "side", etc., generally based on the relative relationship of the directions shown in the drawings, and the use of these directional terms is only to more clearly describe the relationship between the structures and the structures, rather than to describe the absolute directions. When the product is placed in different postures, the directions may change. For example, "upper" and "lower" may be interchanged.

[0050] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meaning as commonly understood by those of ordinary skill in the art.

[0051] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0052] As Figure 1 shown, the present application provides a tilt-rotor unfolding and folding mechanism, which includes a wing body plate 1, a fixed wing 2, a tilt-rotor 4, and a switching and locking assembly 5.

[0053] Exemplarily, the tilt-rotor unfolding and folding mechanism is applicable to a flying car with a compound wing.

[0054] Figure 1 A spatial rectangular coordinate system XYZ is established. Exemplarily, the first direction X is the width direction of the tilt-rotor unfolding and folding mechanism and the flying car, the second direction Z is the height direction of the tilt-rotor unfolding and folding mechanism and the flying car, the third direction Y is the length direction of the tilt-rotor unfolding and folding mechanism and the flying car, and the first direction X, the second direction Z, and the third direction Y are perpendicular to each other pairwise.

[0055] There are two fixed wings 2, two tilt-rotors 4, and two switching and locking assemblies 5. The two fixed wings 2 are symmetrically arranged with respect to the YOZ plane and are respectively connected to the wing body plate 1, and the two tilt-rotors 4 are symmetrically arranged with respect to the YOZ plane. It can be understood that the YOZ plane is a plane perpendicular to the first direction X.

[0056] Please refer to Figure 3 , the tilt-rotor 4 includes a boom 40 and at least two rotor blades 42. The at least two rotor blades 42 are respectively mounted at both ends of the boom 40. The boom 40 is rotatably mounted on the fixed wing 2 around a rotation axis 100 through a switching and locking assembly 5.

[0057] The tilt-rotor 4 is configured to be able to switch between a deployed position and a folded position. In the deployed position, the extending direction of the boom 40 is perpendicular to the extending direction of the fixed wing 2; in the folded position, the extending direction of the boom 40 is parallel to the extending direction of the fixed wing 2.

[0058] Exemplarily, the flying car includes a cockpit, and the wing body plate 1 is located on the cockpit. For example, the wing body plate 1 can be a part of the structure of the cockpit or an additional structural member on the cockpit, and is fixedly connected to the cockpit by means of welding, fastener connection, etc.

[0059] Among them, in each tilt-rotor 4, the number of rotor blades 42 is two, four, six or more. For example Figure 3 as shown, each tilt-rotor 4 includes two rotor blades 42, and the two rotor blades 42 are respectively mounted at both ends of the boom 40.

[0060] The boom 40 is rotatably mounted on the fixed wing 2 around the rotation axis 100 through the switching and locking assembly 5, and the boom 40 can be locked or unlocked in the deployed position and the folded position. When the boom 40 is locked in the deployed position or the folded position, the tilt-rotor 4 can be stably held in the deployed position or the folded position; when the boom 40 is unlocked in the deployed position or the folded position, the tilt-rotor 4 can be switched between the deployed position and the folded position by rotating the boom 40.

[0061] The rotation axis 100 is respectively perpendicular to the plane where the fixed wing 2 is located and the extending direction of the boom 40. For example, when the fixed wing 2 is in the XOY plane and the boom 40 extends along the third direction Y, the rotation axis 100 extends along the second direction Z. Through this setting, it can be avoided that when the boom 40 switches positions, the boom 40 or the rotor blade 42 collides with the fixed wing 2.

[0062] When the tilt-rotor 4 is in the deployed position, the extending direction of the boom 40 is perpendicular to the extending direction of the fixed wing 2. For example, when the fixed wing 2 extends along the first direction X, the boom 40 extends along the third direction Y. Through this setting, at least two rotor blades 42 of each tilt-rotor 4 are respectively located on both sides of the width direction of the fixed wing 2 (i.e., Figure 1 the third direction Y in

[0063] When the tilt-rotor 4 is in the folded position, the extending direction of the swing arm rod 40 is parallel to the extending direction of the fixed wing 2. For example, when the fixed wing 2 extends along the first direction X, the swing arm rod 40 also extends along the first direction X. The tilt-rotor 4 can be at least partially received under the fixed wing 2, reducing the space occupied in the width direction of the fixed wing 2.

[0064] When the fixed wing 2 can be folded, the tilt-rotor 4 can also be folded with the fixed wing 2 to both sides in the width direction of the flying vehicle, reducing the space occupied in the first direction X.

[0065] In the tilt-rotor deployment and folding mechanism provided by the embodiments of the present application, since the swing arm rod 40 is rotatably connected to the fixed wing 2 through the switching locking assembly 5, and the tilt-rotor 4 can be switched between the deployed position and the folded position, therefore, by locking the tilt-rotor 4 in the folded position, making the extending direction of the swing arm rod 40 parallel to the extending direction of the fixed wing 2, the space occupied by the fixed wing 2 in its own extending direction can be fully utilized, reducing the extra space occupied by the tilt-rotor 4, realizing the storage of the tilt-rotor 4, and preventing the rotary wing 42 from causing harm to passers-by when the flying vehicle is driving on a conventional road.

[0066] In some embodiments, the tilt-rotor 4 further includes a cantilever seat 41. The cantilever seat 41 is fixed on the swing arm rod 40 and protrudes outward relative to the side wall of the swing arm rod 40. A disc lock piece 41-1 protrudes from the cantilever seat 41.

[0067] The switching locking assembly 5 has a Y-direction locking groove 500 and an X-direction locking groove 501 arranged at intervals. When the disc lock piece 41-1 cooperates with the Y-direction locking groove 500, the tilt-rotor 4 is in the deployed position; when the disc lock piece 41-1 cooperates with the X-direction locking groove 501, the tilt-rotor 4 is in the folded position.

[0068] The cantilever seat 41 protrudes outward relative to the side wall of the swing arm rod 40 along the extending direction of the rotation axis 100. The disc lock piece 41-1 protrudes outward relative to the side wall of the cantilever seat 41. The Y-direction locking groove 500 and the X-direction locking groove 501 are arranged at intervals around the rotation axis 100. By driving the swing arm rod 40 to rotate around the rotation axis 100, the disc lock piece 41-1 can be moved from the Y-direction locking groove 500 into the X-direction locking groove 501, or the disc lock piece 41-1 can be moved from the X-direction locking groove 501 into the Y-direction locking groove 500, realizing the switching of the tilt-rotor 4 between the deployed position and the folded position.

[0069] Wherein, when the tilt-rotor 4 is in the deployed position, the disc lock piece 41-1 can be locked in the Y-direction locking groove 500; when the tilt-rotor 4 is in the folded state, the disc lock piece 41-1 can be locked in the X-direction locking groove 501.

[0070] In some embodiments, in each tilt-rotor 4, there are two disc lock pieces 41-1, and the two disc lock pieces 41-1 are symmetrically arranged along a direction perpendicular to the rotation axis 100. In each switching lock assembly 5, there are two Y-direction lock grooves 500 and two X-direction lock grooves 501 respectively, and the two Y-direction lock grooves 500 and the two X-direction lock grooves 501 are symmetrically arranged with the rotation axis 100 as the center of symmetry.

[0071] As Figure 3 shown, the cantilever seat 41 is cylindrical, and the two disc lock pieces 41-1 are located in the upper region of the cantilever seat 41 and are symmetrically arranged along the radial direction of the cantilever seat 41. Correspondingly, the two Y-direction lock grooves 500 are symmetrically arranged with the rotation axis 100 as the center of symmetry, and the two X-direction lock grooves 501 are symmetrically arranged with the rotation axis 100 as the center of symmetry, so as to be adapted to the positions of the two disc lock pieces 41-1.

[0072] Optionally, the disc lock piece 41-1 and the cantilever seat 41 can be of an integral structure, or can be connected together by means of welding, fastener connection, etc., and the present application does not make specific limitations.

[0073] In this embodiment, by respectively setting the disc lock piece 41-1, the Y-direction lock groove 500 and the X-direction lock groove 501 to be two and symmetrically distributed, it is beneficial to improve the balance and force uniformity during locking, reduce unilateral wear, and extend the service life of the switching lock assembly 5 and the tilt-rotor 4.

[0074] In some embodiments, please refer to Figure 3 , the switching lock assembly 5 includes a lock sleeve 50, a Y-direction lock latch 52, an X-direction lock latch 53 and a locking and unlocking structure 51.

[0075] One end of the lock sleeve 50 is fixed to the fixed wing 2.

[0076] Please refer to Figure 5 , the Y-direction lock latch 52 and the X-direction lock latch 53 are both fixed to the inner wall of the lock sleeve 50, and the Y-direction lock latch 52 and the X-direction lock latch 53 are distributed along the circumferential direction of the lock sleeve 50.

[0077] The Y-direction lock latch 52 includes a connected Y-upper lock latch 52-2 and a Y-lower lock latch 52-1, and the Y-upper lock latch 52-2 and the Y-lower lock latch 52-1 form the Y-direction lock groove 500.

[0078] The X-direction lock latch 53 includes a connected X-upper lock latch 53-2 and an X-lower lock latch 53-1, and the X-upper lock latch 53-2 and the X-lower lock latch 53-1 form the X-direction lock groove 501.

[0079] The locking and unlocking structure 51 at least partially extends between the Y-direction locking buckle 52 and the X-direction locking buckle 53. The locking and unlocking structure 51 is used to circumferentially limit the disc lock piece 41-1 in the Y-direction lock groove 500 and the X-direction lock groove 501. The locking and unlocking structure 51 is slidably connected to the lock sleeve 50, and the locking and unlocking structure 51 can move relative to the lock sleeve 50 along the extension direction of the rotation axis 100.

[0080] As Figure 2 or Figure 3 shown, the lock sleeve 50 is generally cylindrical, and the inside of the lock sleeve 50 is hollow.

[0081] The length direction of the lock sleeve 50 is parallel to the extension direction of the rotation axis 100, and one end in the length direction of the lock sleeve 50 is fixedly connected to the fixed wing 2. For example Figure 2 or Figure 3 shown, a flange is provided at one end of the lock sleeve 50, and the lock sleeve 50 can be fixedly connected to the fixed wing 2 by bolts, welding or other means through the flange.

[0082] Both the Y-direction locking buckle 52 and the X-direction locking buckle 53 are provided on the inner wall surface of the lock sleeve 50. The Y-direction locking buckle 52 is configured with a Y-direction lock groove 500, and the X-direction locking buckle 53 is configured with an X-direction lock groove 501. Both the Y-direction lock groove 500 and the X-direction lock groove 501 extend along the circumferential direction of the lock sleeve 50. At least part of the locking and unlocking structure 51 can be located between the Y-direction locking buckle 52 and the X-direction locking buckle 53, so as to limit the circumferential movement of the disc lock piece 41-1 in the Y-direction lock groove 500 and the X-direction lock groove 501, and stably maintain the tilt-rotor 4 in the deployed position or the folded position.

[0083] Specifically, as Figure 7As shown, the Y-direction latch 52 includes a connected Y-upward latch 52-2, a first connecting arm 52-3, and a Y-downward latch 52-1. The Y-upward latch 52-2 and the Y-downward latch 52-1 are spaced apart along the extension direction of the rotation axis 100, and one end of the Y-upward latch 52-2 and one end of the Y-downward latch 52-1 are respectively connected to the first connecting arm 52-3. The length direction of the first connecting arm 52-3 is parallel to the extension direction of the rotation axis 100. Among them, the first connecting arm 52-3 is integrally connected to the Y-downward latch 52-1, the first connecting arm 52-3 is connected to the Y-upward latch 52-2 through threaded fasteners such as screws and bolts, and the Y-downward latch 52-1 and the first connecting arm 52-3 can also be integrally formed with the lock sleeve 50. The Y-upward latch 52-2 and the Y-downward latch 52-1 both extend in an arc shape. The arc length of the Y-upward latch 52-2 is less than the arc length of the Y-downward latch 52-1. The Y-upward latch 52-2, the Y-downward latch 52-1, and the first connecting arm 52-3 enclose to form a Y-direction lock groove 500, and the side wall of the first connecting arm 52-3 constitutes the bottom of the Y-direction lock groove 500, the upper surface of the Y-downward latch 52-1 constitutes the lower groove wall of the Y-direction lock groove 500, and the lower surface of the Y-upward latch 52-2 constitutes the upper groove wall of the Y-direction lock groove 500.

[0084] Specifically, as Figure 8 shown, the X-direction latch 53 includes a connected X-upward latch 53-2, a second connecting arm 53-3, and an X-downward latch 53-1. The X-upward latch 53-2 and the X-downward latch 53-1 are spaced apart along the extension direction of the rotation axis 100, and one end of the X-upward latch 53-2 and one end of the X-downward latch 53-1 are respectively connected to the second connecting arm 53-3. The length direction of the second connecting arm 53-3 is parallel to the extension direction of the rotation axis 100. Among them, the second connecting arm 53-3 is integrally connected to the X-downward latch 53-1, the second connecting arm 53-3 is connected to the X-upward latch 53-2 through threaded fasteners such as screws and bolts, and the X-downward latch 53-1 and the second connecting arm 53-3 can also be integrally formed with the lock sleeve 50. The X-upward latch 53-2 and the X-downward latch 53-1 both extend in an arc shape. The arc length of the X-upward latch 53-2 is less than the arc length of the X-downward latch 53-1. The X-upward latch 53-2, the X-downward latch 53-1, and the second connecting arm 53-3 enclose to form an X-direction lock groove 501, and the side wall of the second connecting arm 53-3 constitutes the bottom of the X-direction lock groove 501, the upper surface of the X-downward latch 53-1 constitutes the lower groove wall of the X-direction lock groove 501, and the lower surface of the X-upward latch 53-2 constitutes the upper groove wall of the X-direction lock groove 501.

[0085] When the tilt-rotor 4 is in the deployed position, the disc lock piece 41-1 is located in the Y-direction lock groove 500. The bottom of the Y-direction lock groove 500 and the locking and unlocking structure 51 jointly limit the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50, making it difficult for the disc lock piece 41-1 and the Y-direction lock catch 52 to have relative movement. For example, the bottom of the Y-direction lock groove 500 abuts against one side surface of the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50, and the locking and unlocking structure 51 abuts against the other side surface of the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50 at the top of the Y-direction lock groove 500. The disc lock piece 41-1 is locked in the Y-direction lock groove 500, and the tilt-rotor 4 is locked in the deployed position.

[0086] When the tilt-rotor 4 is in the folded position, the disc lock piece 41-1 is located in the X-direction lock groove 501. The bottom of the X-direction lock groove 501 and the locking and unlocking structure 51 jointly limit the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50, making it difficult for the disc lock piece 41-1 and the X-direction lock catch 53 to have relative movement. For example, the bottom of the X-direction lock groove 501 abuts against one side surface of the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50, and the locking and unlocking structure 51 abuts against the other side surface of the disc lock piece 41-1 in the circumferential direction of the lock sleeve 50 at the top of the X-direction lock groove 501. The disc lock piece 41-1 is locked in the X-direction lock groove 501, and the tilt-rotor 4 is locked in the folded position.

[0087] Since the locking and unlocking structure 51 is slidably connected to the lock sleeve 50 and can move relative to the lock sleeve 50 along the extension direction of the rotation axis 100, the locking and unlocking structure 51 can release the locking of the disc lock piece 41-1 through its own movement, so that the tilt-rotor 4 can be switched between the deployed position and the folded position.

[0088] Exemplarily, when the tilt-rotor 4 is in the deployed position, at least part of the locking and unlocking structure 51 is moved along the extension direction of the rotation axis 100, so that the locking and unlocking structure 51 is disengaged from the side surface of the disc lock piece 41-1. At this time, the disc lock piece 41-1 is unlocked and can move circumferentially along the lock sleeve 50, so that it can disengage from the Y-direction lock groove 500 and enter the X-direction lock groove 501 to switch the tilt-rotor 4 to the folded position. When the tilt-rotor 4 is switched to the folded position, the locking and unlocking structure 51 can move in the reverse direction along the extension direction of the rotation axis 100, so that the locking and unlocking structure 51 abuts against the side surface of the disc lock piece 41-1 again, locking the tilt-rotor 4 in the folded position.

[0089] In some embodiments, the locking and unlocking structure 51 includes a slider 51-1, a bridging arm 51-2, and an elastic member 51-3.

[0090] As Figure 6As shown, the slider 15-1 is fan-shaped, the slider 51-1 is located between the Y-direction lock 52 and the X-direction lock 53, the bridging arm 51-2 is connected to the slider 51-1 and the elastic member 51-3 respectively, and the end of the elastic member 51-3 away from the bridging arm 51-2 is in contact with the fixed wing 2, and the elastic member 51-3 can produce elastic deformation along the extension direction of the rotation axis 100.

[0091] In the circumferential direction of the locking sleeve 50, the slider 51-1 is located between the Y-direction locking groove 500 and the X-direction locking groove 501. The slider 51-1 is used to limit the circumferential movement of the disc locking plate 41-1 in the Y-direction locking groove 500 and the X-direction locking groove 501, thereby stably maintaining the tilt rotor 4 in the deployed position or the folded position.

[0092] The number of sliders 51 - 1 is at least one, and can be specifically set according to the number of Y-direction locking slots 500 and X-direction locking slots 501. For example, if there are two Y-direction locking slots 500 and two X-direction locking slots 501, there are also two sliders 51 - 1, and each slider 51 - 1 is located between a Y-direction locking slot 500 and an X-direction locking slot 501.

[0093] For example, the elastic member 51-3 is a compression spring. Figure 4 As shown, the upper end of the elastic member 51-3 is used to contact the fixed wing 2, and the lower end of the elastic member 51-3 is connected to the middle part of the bridging arm 51-2. The bridging arm 51-2 extends in a direction perpendicular to the direction of the rotation axis 100. In the case where there are two sliders 51-1, one end of the bridging arm 51-2 is connected to one slider 51-1, and the other end of the bridging arm 51-2 is connected to the other slider 51-1.

[0094] By providing the elastic member 51 - 3 , an automatic reset function is provided for the locking and unlocking structure 51 , thereby enabling flexible switching of the locking and unlocking structure 51 between the locking and unlocking states.

[0095] Exemplarily, when the tilt-rotor 4 is in the deployed position and the elastic member 51-3 is in the maximum length state, the slider 51-1 is in a position where it can abut against the side surface of the disc lock piece 41-1, so as to lock the disc lock piece 41-1 and the tilt-rotor 4. When the slider 51-1 is pressed along the extension direction of the rotation axis 100 towards the side where the elastic member 51-3 is located, the slider 51-1 is separated from the disc lock piece 41-1, and the elastic member 51-3 is compressed. At this time, the locking and unlocking structure 51 unlocks the disc lock piece 41-1, and the disc lock piece 41-1 can move from the Y-direction locking groove 500 to the X-direction locking groove 501, so that the tilt-rotor 4 is switched from the deployed position to the folded position. After the tilt-rotor 4 is switched to the folded position, the external force applied to the slider 51-1 is released, and the elastic member 51-3 automatically extends under the action of the elastic force, driving the slider 51-1 to move along the extension direction of the rotation axis 100 towards the side away from the elastic member 51-3, so that the slider 51-1 abuts against the side surface of the disc lock piece 41-1 again, thereby locking the tilt-rotor 4 in the folded position.

[0096] Among them, as Figure 4 shown, when the elastic member 51-3 is in the maximum length state, the position height of the bottom surface of the slider 51-1 is lower than the position height of the lower groove wall of the Y-direction locking groove 500 and the position height of the lower groove wall of the X-direction locking groove 501. Through this setting, no matter whether the disc lock piece 41-1 is located in the Y-direction locking groove 500 or the X-direction locking groove 501, it can be ensured that the contact area between the slider 51-1 and the side surface of the disc lock piece 41-1 is the area of this side surface of the disc lock piece 41-1. That is to say, it can be ensured that the slider 51-1 is in full contact with one side surface of the disc lock piece 41-1 in the circumferential direction of the rotation axis 100, improving the locking effect of the slider 51-1 on the disc lock piece 41-1.

[0097] When the tilt-rotor 4 is in the deployed position, the disc lock piece 41-1 is located in the Y-direction locking groove 500 and is firmly locked by the Y-direction upper lock 52-2, the Y-direction lower lock 52-1 and the slider 51-1. The lift provided by the rotary wing 42 acts on the disc lock piece 41-1 through the rotary arm rod 40 and the cantilever seat 41. The disc lock piece 41-1 acts on the lock sleeve 50 through the Y-direction upper lock 52-2 and the Y-direction lower lock 52-1, and then is transmitted to the fixed wing 2.

[0098] In some embodiments, the linear dimensions of the Y-direction locking groove 500 and the X-direction locking groove 501 in the extension direction of the rotation axis 100 are both adapted to the thickness of the disc lock piece 41-1. It can be understood that the thickness of the disc lock piece 41-1 is the dimension of the disc lock piece 41-1 in the extension direction of the rotation axis 100.

[0099] Wherein, the above-mentioned "adaptation" means that the linear dimension of the Y-direction locking groove 500 and the X-direction locking groove 501 in the extending direction of the rotation axis 100 can be equal to the thickness of the disc lock piece 41-1, or slightly larger than the thickness of the disc lock piece 41-1.

[0100] With this setting, when the disc lock piece 41-1 is locked in the Y-direction locking groove 500 or the X-direction locking groove 501, through the matching of the Y-direction locking groove 500 / X-direction locking groove 501 and the thickness of the disc lock piece 41-1, the disc lock piece 41-1 can be limited in the extending direction of the rotation axis 100, avoiding the disc lock piece 41-1 from moving axially in the extending direction of the rotation axis 100, which is beneficial to improving the stability of the tiltrotor 4.

[0101] In some embodiments, the position height of the X-direction locking groove 501 in the extending direction of the rotation axis 100 is greater than the position height of the Y-direction locking groove 500 in the extending direction of the rotation axis 100, so that the Y-direction locking groove 500 and the X-direction locking groove 501 are arranged in a staggered manner in the extending direction of the rotation axis 100. Among them, the position height of the lower groove wall of the X-direction locking groove 501 is at least greater than the position height of the lower groove wall of the Y-direction locking groove 500.

[0102] When the position heights of the Y-direction locking groove 500 and the X-direction locking groove 501 in the extending direction of the rotation axis 100 are the same, when the rotating arm rod 40 is rotated to make the disc lock piece 41-1 move between the Y-direction locking groove 500 and the X-direction locking groove 501, it is easy for the disc lock piece 41-1 to enter the wrong locking groove. For example, when the disc lock piece 41-1 needs to enter the Y-direction locking groove 500, the disc lock piece 41-1 is accidentally rotated into the X-direction locking groove 501; or, when the disc lock piece 41-1 needs to enter the X-direction locking groove 501, the disc lock piece 41-1 is accidentally rotated into the Y-direction locking groove 500.

[0103] In the embodiment of the present application, by arranging the X-direction locking groove 501 and the Y-direction locking groove 500 to be staggered in the extending direction of the rotation axis 100, the distinguishability of the Y-direction locking groove 500 and the X-direction locking groove 501 can be improved, avoiding the disc lock piece 41-1 from entering the wrong locking groove during rotation.

[0104] Moreover, since the position height of the X-direction locking groove 501 in the extending direction of the rotation axis 100 is higher than the position height of the Y-direction locking groove 500 in the extending direction of the rotation axis 100, the distance between the X-direction locking groove 501 and the fixed wing 2 is closer. Compared with when the disc lock piece 41-1 is locked in the Y-direction locking groove 500, when the disc lock piece 41-1 is locked in the X-direction locking groove 501, the distance between the rotating arm rod 40 and the fixed wing 2 is closer, further reducing the space occupied by the tiltrotor 4 in the extending direction of the rotation axis 100, making the additional space occupied by the tiltrotor 4 in the folded position smaller, which is more beneficial to the storage of the tiltrotor 4.

[0105] In some further embodiments, the difference in the position heights of the X-direction locking groove 501 and the Y-direction locking groove 500 in the extending direction of the rotation axis 100 is greater than or equal to the thickness of the disc locking piece 41-1.

[0106] In this embodiment, the lower groove wall of the X-direction locking groove 501 is flush with the upper groove wall of the Y-direction locking groove 500, or the position height of the lower groove wall of the X-direction locking groove 501 is greater than the position height of the upper groove wall of the Y-direction locking groove 500.

[0107] With this setting, the X-direction locking groove 501 and the Y-direction locking groove 500 are completely staggered in the extending direction of the rotation axis 100. When the slider 51-1 locks the disc locking piece 41-1, the contact area between the side surface of the slider 51-1 and the Y-direction locking buckle 52 or the X-direction locking buckle 53 can be increased, preventing the slider 51-1 from being damaged due to eccentric load.

[0108] For example, when the tilt-rotor 4 is in the deployed position, the disc locking piece 41-1 is located in the Y-direction locking groove 500. One side surface of the slider 51-1 abuts against the side surface of the disc locking piece 41-1, and the other side surface of the slider 51-1 abuts against the side surface of the X-direction locking buckle 53. The force-bearing areas of the two side surfaces of the slider 51-1 are both large, which can better bear the torque and prevent the slider 51-1 from shaking, wearing or even being damaged due to eccentric load.

[0109] In some embodiments, a limiting sliding groove 50-1 is recessed on the inner wall of the locking sleeve 50. The slider 51-1 cooperates with the limiting sliding groove 50-1, and the limiting sliding groove 50-1 is used to define the movement path and the limit position of the slider 51-1.

[0110] The length direction of the limiting sliding groove 50-1 is parallel to the extending direction of the rotation axis 100. A part of the slider 51-1 is located in the limiting sliding groove 50-1, so that the slider 51-1 can move along the extending direction of the rotation axis 100 under the limitation of the limiting sliding groove 50-1, improving the stability of the slider 51-1 during movement.

[0111] Optionally, the width dimension of the limiting sliding groove 50-1 in the circumferential direction of the rotation axis 100 matches the width dimension of the slider 51-1 in the circumferential direction of the rotation axis 100, that is, the width dimension of the limiting sliding groove 50-1 in the circumferential direction of the rotation axis 100 is equal to the width dimension of the slider 51-1 in the circumferential direction of the rotation axis 100, or the width dimension of the limiting sliding groove 50-1 in the circumferential direction of the rotation axis 100 is slightly larger than the width dimension of the slider 51-1 in the circumferential direction of the rotation axis 100, so that the limiting sliding groove 50-1 can also limit the slider 51-1 in the circumferential direction of the rotation axis 100.

[0112] The top wall of the limit sliding groove 50-1 defines the limit position of the slider 51-1 when moving towards the side close to the fixed wing 2. When the slider 51-1 moves to abut against the top wall of the limit sliding groove 50-1, it cannot move further upward, and the operator can be reminded by the feel that the slider 51-1 has reached the limit position. Optionally, when the slider 51-1 moves to abut against the top wall of the limit sliding groove 50-1, the lower surface of the slider 51-1 is flush with or higher than the upper groove wall of the X-direction locking groove 501, so that the disc locking piece 41-1 can smoothly enter or disengage from the X-direction locking groove 501.

[0113] The bottom wall of the limit sliding groove 50-1 defines the limit position of the slider 51-1 when moving towards the side away from the fixed wing 2. When the slider 51-1 moves to abut against the bottom wall of the limit sliding groove 50-1, it cannot move further downward, and at this time, the elastic member 51-3 is in the maximum length state.

[0114] In one embodiment, the process of switching the tilt-rotor 4 from the deployed position to the folded position includes:

[0115] (1) The tilt-rotor 4 is in the deployed position, the disc locking piece 41-1 is located in the Y-direction locking groove 500, and is firmly locked by the Y-direction upper locking buckle 52-2, the X-direction upper locking buckle 53-2 and the slider 51-1. The operator presses the slider ⑤ upward, causing the slider 51-1 to move towards the side close to the fixed wing 2. The slider 51-1 squeezes the elastic member 51-3 through the bridging arm 51-2 until the lower surface of the sector-shaped slider 51-1 moves above the upper groove wall of the Y-direction locking groove 500;

[0116] (2) Rotate the swivel arm rod 40 around the rotation axis 100, so that the swivel arm rod 40 and the cantilever seat 41 drive the disc locking piece 41-1 to rotate around the rotation axis 100 to directly below the slider 51-1, and the disc locking piece 41-1 abuts against the lower surface of the slider 51-1;

[0117] (3) Push the swivel arm rod 40 along the extension direction of the rotation axis 100, so that the disc locking piece 41-1 further squeezes the elastic member 51-3 through the slider 51-1 until the slider 51-1 moves to the limit position and abuts against the top wall of the limit sliding groove 50-1;

[0118] (4) Rotate the swivel arm rod 40 around the rotation axis 100, so that the swivel arm rod 40 and the cantilever seat 41 drive the disc locking piece 41-1 to rotate around the rotation axis 100 into the X-direction locking groove

[0119] (5) Under the elastic restoring force of the elastic member 51-3, the slider 51-1 slides in the limit chute 50-1 until the slider 51-1 moves to abut against the bottom wall of the limit chute 50-1. At this time, the disc lock piece 41-1 is in the X-direction lock groove 501 and is firmly locked by the X-direction upper lock 53-2, the X-direction lower lock 53-1 and the slider 51-1. The tilt-rotor 4 is switched from the deployed position to the folded position.

[0120] The present application also provides an aerial vehicle, including the tilt-rotor deployment and folding mechanism provided in any of the above embodiments.

[0121] The aerial vehicle further includes a cockpit, and the wing body plate 1 of the fixed-wing 2 deployment and folding mechanism is located on the cockpit. For example, the wing body plate 1 may be a part of the structure of the cockpit or an additional structural member on the cockpit, and is fixedly connected to the cockpit by means of welding, fastener connection, etc. In the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The term "plurality" means two or more, unless otherwise clearly defined.
