Description

[0001] This application claims priority to Chinese Patent Application No. 202510644325.1, filed on May 19, 2025, entitled "Tilted Rotor Deployment and Folding Mechanism and Flying Car", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of flying car technology, and in particular to a tilting rotor unfolding and folding mechanism for a flying car and a flying car. Background Technology

[0003] In recent years, with the technological development of future transportation and the low-altitude economy, the concept of flying cars has emerged. Flying cars can achieve seamless air-to-ground transfer of people and goods. Their applications are wide-ranging, including air taxis to alleviate urban traffic congestion, aerial law enforcement, emergency rescue, low-altitude logistics, and tourism.

[0004] To generate the lift required for flight, flying cars need to have relatively long fixed wings. Furthermore, to enable vertical takeoff and landing, tiltrotors must be installed on the fixed wings.

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

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

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

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

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

[0010] The tilting rotor includes a rotor arm and at least two rotating blades, the at least two rotating blades being respectively mounted at both ends of the rotor arm, and the rotor arm being rotatably mounted to the fixed blade about the rotation axis via the switching locking assembly;

[0011] The tilt rotor is configured to switch between an extended position and a folded position, wherein in the extended position, the extension direction of the rotor arm is perpendicular to the extension direction of the fixed wing; and in the folded position, the extension direction of the rotor arm is parallel to the extension direction of the fixed wing.

[0012] In one possible implementation, the tilt rotor further includes a cantilever base, which is fixed to the rotor arm and protrudes outward relative to the side wall of the rotor arm, and a disc locking plate is protruding from the cantilever base;

[0013] The switching locking assembly has Y-direction locking grooves and X-direction locking grooves spaced apart. When the disc locking plate engages with the Y-direction locking groove, the tilting rotor is in the unfolded position; when the disc locking plate engages with the X-direction locking groove, the tilting rotor is in the folded position.

[0014] In one possible implementation, in each tilting rotor, there are two disc locking plates, and the two disc locking plates are symmetrically arranged along a direction perpendicular to the rotation axis;

[0015] In each of the aforementioned switching locking components, there are two Y-direction locking slots and two X-direction locking slots, which are symmetrically arranged with the rotation axis as the center of symmetry.

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

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

[0018] Both the Y-direction latch and the X-direction latch are fixed to the inner wall of the lock sleeve, and the Y-direction latch and the X-direction latch are distributed along the circumference of the lock sleeve;

[0019] The Y-direction latch includes a connected Y-up latch and a Y-down latch, the Y-up latch and the Y-down latch forming the Y-direction locking groove;

[0020] The X-direction latch includes an X-up latch and an X-down latch connected together, and the X-up latch and the X-down latch form the X-direction locking groove;

[0021] The locking and unlocking structure extends at least partially between the Y-direction latch and the X-direction latch. The locking and unlocking structure is used to circumferentially limit the disc locking piece in the Y-direction locking groove and the X-direction locking groove. The locking and unlocking structure is slidably connected to the lock sleeve. The locking and unlocking structure is capable of moving relative to the lock sleeve along the extension direction of the rotation axis.

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

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

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

[0025] In one possible implementation, the X-direction locking groove is positioned at a higher height in the extension direction of the rotation axis than the Y-direction locking groove in the extension direction of the rotation axis, so that the Y-direction locking groove and the X-direction locking groove are misaligned in the extension direction of the rotation axis.

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

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

[0028] Secondly, this application provides a flying car, which includes the tilt rotor unfolding and folding mechanism provided in any embodiment of the first aspect.

[0029] The beneficial effects of the technical solution provided in this application embodiment include at least the following: since the rotor arm is rotatably connected to the fixed wing through the switching locking assembly, and the tilt rotor can switch between the unfolded position and the folded position, by locking the tilt rotor in the folded position, the extension direction of the rotor arm is parallel to the extension direction of the fixed wing, which can make full use of the space occupied by the fixed wing in its own extension direction, reduce the extra space occupied by the tilt rotor, realize the storage of the tilt rotor, and ensure that the rotor does not cause harm to pedestrians when the flying car is driving on a regular road.

Detailed Implementation

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] The directional terms used in the embodiments of this application, such as "up," "down," and "side," are generally based on the relative relationships shown in the figures. These directional terms are used merely to more clearly describe the relationships between structures, not to describe absolute directions. When the product is placed in different orientations, the orientation may change; for example, "up" and "down" may be interchanged.

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

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

[0052] like Figure 1 As shown, this application provides a tilt rotor unfolding and folding mechanism, including a wing plate 1, a fixed wing 2, a tilt rotor 4, and a switching locking assembly 5.

[0053] For example, the tilt rotor deployment and folding mechanism is suitable for flying cars with compound wings.

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

[0055] There are two fixed wings 2, two tilting rotors 4, and two switching locking components 5. The two fixed wings 2 are symmetrically arranged about the YOZ plane and are respectively connected to the wing body plate 1. The two tilting rotors 4 are symmetrically arranged about 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 tilting rotor 4 includes a rotor arm 40 and at least two rotating blades 42. The at least two rotating blades 42 are respectively installed at both ends of the rotor arm 40. The rotor arm 40 is rotatably installed on the fixed blade 2 around the rotation axis 100 by a switching locking assembly 5.

[0057] The tilt rotor 4 is configured to switch between an extended position and a folded position. In the extended position, the extension direction of the rotor arm 40 is perpendicular to the extension direction of the fixed wing 2; in the folded position, the extension direction of the rotor arm 40 is parallel to the extension direction of the fixed wing 2.

[0058] For example, the flying car includes a cockpit, and the wing panel 1 is located on the cockpit. For example, the wing panel 1 can be part of the cockpit structure or an additional structural component on the cockpit, which is fixedly connected to the cockpit by means of welding, fasteners or other methods.

[0059] In each tilting rotor 4, the number of rotating blades 42 can be two, four, six or more, for example... Figure 3 As shown, each tilting rotor 4 includes two rotating blades 42, which are respectively mounted at both ends of the rotating arm 40.

[0060] The swivel arm 40 is rotatably mounted on the fixed wing 2 about the rotation axis 100 via the switching locking assembly 5, and the swivel arm 40 can be locked or unlocked in the deployed and folded positions. When the swivel arm 40 is locked in the deployed or folded position, the tilting rotor 4 can be stably maintained in the deployed or folded position; when the swivel arm 40 is unlocked in the deployed or folded position, the tilting rotor 4 can be switched between the deployed and folded positions by rotating the swivel arm 40.

[0061] The rotation axis 100 is perpendicular to both the plane of the fixed wing 2 and the extension direction of the rotating arm 40. For example, when the fixed wing 2 is located in the XOY plane and the rotating arm 40 extends along the third direction Y, the rotation axis 100 extends along the second direction Z. This arrangement prevents the rotating arm 40 or the rotating wing 42 from colliding with the fixed wing 2 when the rotating arm 40 changes position.

[0062] When the tilting rotor 4 is in the deployed position, the extension direction of the rotating arm 40 is perpendicular to the extension direction of the fixed wing 2. For example, when the fixed wing 2 extends along the first direction X, the rotating arm 40 extends along the third direction Y. With this arrangement, at least two rotating blades 42 of each tilting rotor 4 are respectively located in the width direction of the fixed wing 2 (i.e., Figure 1 The third party in the middle (Y) is positioned on both sides to ensure that the flying car can take off and land smoothly and vertically.

[0063] When the tilt rotor 4 is in the folded position, the extension direction of the rotor arm 40 is parallel to the extension direction of the fixed wing 2. For example, when the fixed wing 2 extends along the first direction X, the rotor arm 40 also extends along the first direction X. The tilt rotor 4 can be at least partially housed 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 along with the fixed wing 2 to both sides in the width direction of the flying car, reducing the space occupied in the first direction X.

[0065] The tilt rotor deployment and folding mechanism provided in this application embodiment, since the rotor arm 40 is rotatably connected to the fixed wing 2 through the switching locking assembly 5, and the tilt rotor 4 can switch between the deployed position and the folded position, by locking the tilt rotor 4 in the folded position, the extension direction of the rotor arm 40 is parallel to the extension direction of the fixed wing 2, which can make full use of the space occupied by the fixed wing 2 in its own extension direction, reduce the extra space occupied by the tilt rotor 4, realize the storage of the tilt rotor 4, and ensure that the rotor 42 will not cause harm to pedestrians when the flying car is driving on a regular road.

[0066] In some embodiments, the tilt rotor 4 further includes a cantilever seat 41, which is fixed to the rotor arm 40 and protrudes outward relative to the side wall of the rotor arm 40. A disc locking piece 41-1 is protruding 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 spaced apart. When the disc locking plate 41-1 engages with the Y-direction locking groove 500, the tilting rotor 4 is in the unfolded position; when the disc locking plate 41-1 engages with the X-direction locking groove 501, the tilting rotor 4 is in the folded position.

[0068] The cantilever base 41 protrudes outward relative to the side wall of the rotating arm 40 along the extension direction of the rotation axis 100, and the disc locking plate 41-1 protrudes outward relative to the side wall of the cantilever base 41. The Y-direction locking groove 500 and the X-direction locking groove 501 are spaced apart around the rotation axis 100. By driving the rotating arm 40 to rotate around the rotation axis 100, the disc locking plate 41-1 can be moved from the Y-direction locking groove 500 to the X-direction locking groove 501, or vice versa, thereby switching the tilt rotor 4 between the deployed position and the folded position.

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

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

[0071] like Figure 3 As shown, the cantilever base 41 is cylindrical, and the two disc locking plates 41-1 are located in the upper region of the cantilever base 41 and are symmetrically arranged radially along the cantilever base 41. Correspondingly, the two Y-direction locking grooves 500 are symmetrically arranged with the rotation axis 100 as the center of symmetry, and the two X-direction locking grooves 501 are symmetrically arranged with the rotation axis 100 as the center of symmetry, thus adapting to the positions of the two disc locking plates 41-1.

[0072] Optionally, the disc locking plate 41-1 and the cantilever seat 41 can be an integral structure, or they can be connected together by welding, fasteners or other methods. This application does not make any specific limitations.

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

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

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

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

[0077] The Y-direction latch 52 includes a connected Y-up latch 52-2 and a Y-down latch 52-1, which together form a Y-direction locking groove 500.

[0078] The X-direction latch 53 includes an X-up latch 53-2 and an X-down latch 53-1 connected together, which form an X-direction locking groove 501.

[0079] The locking and unlocking structure 51 extends at least partially between the Y-direction latch 52 and the X-direction latch 53. The locking and unlocking structure 51 is used to circumferentially limit the disc locking 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. The locking and unlocking structure 51 can move relative to the lock sleeve 50 along the extension direction of the rotation axis 100.

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

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

[0082] Both the Y-direction latch 52 and the X-direction latch 53 are disposed on the inner wall surface of the lock sleeve 50. The Y-direction latch 52 is constructed with a Y-direction locking groove 500, and the X-direction latch 53 is constructed with an X-direction locking groove 501. Both the Y-direction locking groove 500 and the X-direction locking groove 501 extend circumferentially along the lock sleeve 50. At least part of the locking and unlocking structure 51 can be located between the Y-direction latch 52 and the X-direction latch 53, thereby restricting the circumferential movement of the disc locking plate 41-1 in the Y-direction locking groove 500 and the X-direction locking groove 501, and stably maintaining the tilting rotor 4 in the unfolded or folded position.

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

[0084] Specifically, such as Figure 8 As shown, the X-direction latch 53 includes an X-up latch 53-2, a second connecting arm 53-3, and an X-down latch 53-1 connected together. The X-up latch 53-2 and the X-down latch 53-1 are spaced apart along the extension direction of the rotation axis 100, and one end of the X-up latch 53-2 and one end of the X-down 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. The second connecting arm 53-3 is integrally connected to the X-down latch 53-1, and the second connecting arm 53-3 is connected to the X-up latch 53-2 by threaded fasteners such as screws and bolts. The X-down latch 53-1 and the second connecting arm 53-3 can also be integrally formed with the locking sleeve 50. Both the X-up locking buckle 53-2 and the X-down locking buckle 53-1 extend in an arc shape. The arc length of the X-up locking buckle 53-2 is less than that of the X-down locking buckle 53-1. The X-up locking buckle 53-2, the X-down locking buckle 53-1, and the second connecting arm 53-3 surround and form an X-direction locking groove 501. The side wall of the second connecting arm 53-3 forms the bottom of the X-direction locking groove 501. The upper surface of the X-down locking buckle 53-1 forms the lower wall of the X-direction locking groove 501, and the lower surface of the X-up locking buckle 53-2 forms the upper wall of the X-direction locking groove 501.

[0085] 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. The bottom of the Y-direction locking groove 500 and the locking / unlocking structure 51 together limit the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50, making it difficult for the disc locking piece 41-1 and the Y-direction latch 52 to move relative to each other. For example, the bottom of the Y-direction locking groove 500 abuts against one side surface of the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50, and the locking / unlocking structure 51 abuts against the other side surface of the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50 at the top of the Y-direction locking groove 500. The disc locking piece 41-1 is locked in the Y-direction locking 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 locking piece 41-1 is located in the X-direction locking groove 501. The bottom of the X-direction locking groove 501 and the locking / unlocking structure 51 together limit the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50, making it difficult for the disc locking piece 41-1 and the X-direction latch 53 to move relative to each other. For example, the bottom of the X-direction locking groove 501 abuts against one side surface of the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50, and the locking / unlocking structure 51 abuts against the other side surface of the disc locking piece 41-1 in the circumferential direction of the locking sleeve 50 at the top of the X-direction locking groove 501. The disc locking piece 41-1 is locked in the X-direction locking 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 locking sleeve 50, the locking and unlocking structure 51 can move relative to the locking sleeve 50 along the extension direction of the rotation axis 100. Therefore, the locking and unlocking structure 51 can release the locking of the disc lock plate 41-1 through its own movement, so that the tilting rotor 4 can switch between the unfolded position and the folded position.

[0088] For example, when the tilt rotor 4 is in the deployed position, at least part of the locking / unlocking structure 51 is moved along the extension direction of the rotation axis 100, causing the locking / unlocking structure 51 to disengage from the side 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, thereby disengaging from the Y-direction locking groove 500 and entering the X-direction locking groove 501, allowing the tilt rotor 4 to switch to the folded position. When the tilt rotor 4 switches to the folded position, the locking / unlocking structure 51 can move in the opposite direction along the extension direction of the rotation axis 100, causing the locking / unlocking structure 51 to abut against the side of the disc lock piece 41-1 again, locking the tilt rotor 4 in the folded position.

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

[0090] like Figure 6As shown, slider 15-1 is fan-shaped, slider 51-1 is located between Y-direction latch 52 and X-direction latch 53, bridging arm 51-2 is connected to slider 51-1 and elastic element 51-3 respectively, one end of elastic element 51-3 away from bridging arm 51-2 is in contact with fixed wing 2, and elastic element 51-3 can generate elastic deformation along the extension direction of 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, so as to stably maintain the tilt rotor 4 in the unfolded position or the folded position.

[0092] The number of sliders 51-1 is at least one, and can be 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, with each slider 51-1 located between one Y-direction locking slot 500 and one X-direction locking slot 501.

[0093] For example, the elastic element 51-3 is a compression spring. Figure 4 As shown, the upper end of the elastic element 51-3 is used to contact the fixed wing 2, and the lower end of the elastic element 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 rotation axis 100. When 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 setting the elastic element 51-3, an automatic reset function is provided for the locking and unlocking structure 51, realizing flexible switching between the locking and unlocking states of the locking and unlocking structure 51.

[0095] For example, when the tilt rotor 4 is in the deployed position, and the elastic member 51-3 is at its maximum length, the slider 51-1 is in a position that can abut against the side of the disc locking piece 41-1, thereby locking the disc locking piece 41-1 and the tilt rotor 4. When the slider 51-1 is pressed along the extension direction of the rotation axis 100 toward the side where the elastic member 51-3 is located, the slider 51-1 separates from the disc locking piece 41-1, the elastic member 51-3 is compressed, and at this time the locking and unlocking structure 51 unlocks the disc locking piece 41-1. The disc locking piece 41-1 can move from the Y-direction locking groove 500 to the X-direction locking groove 501, thereby switching the tilt rotor 4 from the deployed position to the folded position. When the tilt rotor 4 is switched to the folded position, the external force on the slider 51-1 is released, and the elastic element 51-3 automatically extends under the action of elastic force, causing the slider 51-1 to move along the extension direction of the rotation axis 100 to the side away from the elastic element 51-3, so that the slider 51-1 abuts against the side of the disc locking piece 41-1 again, thereby locking the tilt rotor 4 in the folded position.

[0096] Among them, such as Figure 4 As shown, when the elastic element 51-3 is at its maximum length, the bottom surface of the slider 51-1 is lower than the lower wall of the Y-direction locking groove 500 and the lower wall of the X-direction locking groove 501. With this setting, regardless of whether the disc locking piece 41-1 is located in the Y-direction locking groove 500 or the X-direction locking groove 501, the contact area between the slider 51-1 and the side of the disc locking piece 41-1 is equal to the area of ​​that side of the disc locking piece 41-1. In other words, it ensures sufficient contact between the slider 51-1 and the side of the disc locking piece 41-1 in the circumferential direction along the rotation axis 100, thus improving the locking effect of the slider 51-1 on the disc locking piece 41-1.

[0097] When the tilt rotor 4 is in the deployed position, the disc locking plate 41-1 is located in the Y-direction locking groove 500 and is firmly locked by the Y-up locking buckle 52-2, the Y-down locking buckle 52-1 and the slider 51-1. The lift provided by the rotating wing 42 acts on the disc locking plate 41-1 through the rotating arm rod 40 and the cantilever seat 41. The disc locking plate 41-1 acts on the locking sleeve 50 through the Y-up locking buckle 52-2 and the Y-down locking buckle 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 locking piece 41-1. It can be understood that the thickness of the disc locking piece 41-1 is the dimension of the disc locking piece 41-1 in the extension direction of the rotation axis 100.

[0099] The term "adaptation" means that the linear dimensions of the Y-axis locking groove 500 and the X-axis locking groove 501 in the extension direction of the rotation axis 100 can be equal to or slightly larger than the thickness of the disc locking piece 41-1.

[0100] With this setting, when the disc locking plate 41-1 is locked in the Y-direction locking groove 500 or the X-direction locking groove 501, the matching of the thickness of the Y-direction locking groove 500 / X-direction locking groove 501 and the disc locking plate 41-1 can limit the disc locking plate 41-1 in the extension direction of the rotation axis 100, prevent the disc locking plate 41-1 from moving in the extension direction of the rotation axis 100, and help improve the stability of the tilt rotor 4.

[0101] In some embodiments, the position height of the X-direction locking groove 501 in the extension direction of the rotation axis 100 is greater than the position height of the Y-direction locking groove 500 in the extension direction of the rotation axis 100, so that the Y-direction locking groove 500 and the X-direction locking groove 501 are misaligned in the extension direction of the rotation axis 100. Specifically, 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 Y-direction locking groove 500 and the X-direction locking groove 501 are at the same height in the extension direction of the rotation axis 100, when the rotary arm 40 is rotated to move the disc locking piece 41-1 between the Y-direction locking groove 500 and the X-direction locking groove 501, the disc locking piece 41-1 is prone to entering the wrong locking groove. For example, when the disc locking piece 41-1 needs to enter the Y-direction locking groove 500, it may be accidentally rotated into the X-direction locking groove 501; or, when the disc locking piece 41-1 needs to enter the X-direction locking groove 501, it may be accidentally rotated into the Y-direction locking groove 500.

[0103] In the embodiments of this application, by setting the X-direction locking groove 501 and the Y-direction locking groove 500 to be misaligned along the extension direction of the rotation axis 100, the recognizability of the Y-direction locking groove 500 and the X-direction locking groove 501 can be improved, and the disc locking piece 41-1 can be prevented from entering the wrong locking groove during rotation.

[0104] Furthermore, since the X-direction locking groove 501 is positioned at a higher height in the extension direction of the rotation axis 100 than the Y-direction locking groove 500 in the same direction, the distance between the X-direction locking groove 501 and the fixed wing 2 is closer. Compared to when the disc locking plate 41-1 is locked in the Y-direction locking groove 500, when the disc locking plate 41-1 is locked in the X-direction locking groove 501, the distance between the rotating arm 40 and the fixed wing 2 is closer, further reducing the space occupied by the tilting rotor 4 in the extension direction of the rotation axis 100. This results in less extra space occupied by the tilting rotor 4 in the folded position, making it more conducive to the storage of the tilting rotor 4.

[0105] In some further embodiments, the difference in position height between the X-direction locking groove 501 and the Y-direction locking groove 500 in the extension 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 wall of the X-direction locking groove 501 is flush with the upper wall of the Y-direction locking groove 500, or the position height of the lower wall of the X-direction locking groove 501 is greater than the position height of the upper 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 offset along the extension direction of the rotation axis 100. When the slider 51-1 locks the disc locking piece 41-1, the contact area between the side 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 off-center load.

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

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

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

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

[0112] The top wall of the limiting groove 50-1 defines the limit position of the slider 51-1 when it moves towards the side closer to the fixed wing 2. When the slider 51-1 moves to abut against the top wall of the limiting groove 50-1, it can no longer move upward, allowing the operator to be alerted by touch that the slider 51-1 has reached its limit position. Optionally, when the slider 51-1 moves to abut against the top wall of the limiting groove 50-1, the lower surface of the slider 51-1 is flush with or higher than the upper 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 limiting groove 50-1 limits the extreme position of the slider 51-1 when it moves away from the fixed wing 2. When the slider 51-1 moves to the point of contact with the bottom wall of the limiting groove 50-1, it can no longer move downward. At this time, the elastic element 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) When the tilting rotor 4 is in the unfolded position, the disc locking plate 41-1 is located in the Y-direction locking groove 500 and is firmly locked by the Y-direction upward locking buckle 52-2, the X-direction upward locking buckle 53-2 and the slider 51-1. The operator presses the slider 51-1 upward, causing the slider 51-1 to move towards the side closer to the fixed wing 2. The slider 51-1 squeezes the elastic element 51-3 through the bridging arm 51-2 until the lower surface of the fan-shaped slider 51-1 moves to a position higher than the upper groove wall of the Y-direction locking groove 500.

[0116] (2) Rotate the swivel arm 40 around the rotation axis 100 so that the swivel arm 40 and the cantilever seat 41, along with the disc lock plate 41-1, rotate around the rotation axis 100 to directly below the slider 51-1, and the disc lock plate 41-1 abuts against the lower surface of the slider 51-1.

[0117] (3) Push the rotating arm rod 40 along the extension direction of the rotation axis 100 so that the disc locking piece 41-1 further squeezes the elastic element 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 limiting groove 50-1.

[0118] (4) Rotate the swivel arm 40 around the rotation axis 100 so that the swivel arm 40 and the cantilever seat 41, along with the disc lock piece 41-1, rotate around the rotation axis 100 into the X-direction lock groove 501.

[0119] (5) Under the elastic restoring force of the elastic element 51-3, the slider 51-1 slides in the limiting groove 50-1 until the slider 51-1 moves to the bottom wall of the limiting groove 50-1 and abuts. At this time, the disc locking piece 41-1 is in the X-direction locking groove 501 and is firmly locked by the X-up locking buckle 53-2, the X-down locking buckle 53-1 and the slider 51-1. The tilting rotor 4 switches from the unfolded position to the folded position.

[0121] The flying car also includes a cockpit, and the wing panel 1 of the fixed wing 2's unfolding and folding mechanism is located on the cockpit.
