Limiting and locking mechanism and flying vehicle

Abstract

The application discloses a limiting and locking mechanism and a flying vehicle, and relates to the technical field of limiting structures. The limiting and locking mechanism comprises a limiting piece, a locking piece, an actuating piece and a matching structure. The locking piece is abutted on the limiting piece under the action of external force to fix the limiting piece. The matching structure moves in the direction close to the limiting piece to drive the actuating piece to move to the first attitude and the second attitude in sequence. When the actuating piece is in the first attitude, the actuating piece pushes the locking piece to overcome the action of external force and separate from the limiting piece, so that the limiting piece is in the active state and is butted against the matching structure. When the actuating piece is in the second attitude, the actuating piece separates from the locking piece, so that the locking piece is abutted on the limiting piece under the action of external force, thereby enabling the limiting piece and the matching structure to complete the limiting cooperation. The scheme can improve the tolerance of the limiting piece and the matching structure. Even if there is a certain position deviation between the limiting piece and the matching structure, the limiting cooperation can be successfully completed through self-adaptive adjustment in the butting process.

Description

Technical Field

[0001] This application relates to the field of limit structure technology, and in particular to a limit locking mechanism and an aircraft. Background Technology

[0002] For most two-part structures, the two separate components need to be combined into a single unit under certain operating conditions. For example, in a split-type flying vehicle, the land vehicle and the aircraft are combined; after use, the aircraft needs to be stored in the land vehicle and transported away. During the combination of the two separate components, limiting components are often used to constrain them and prevent relative displacement after combination.

[0003] For heavy, two-part structures such as split-type flying vehicles, the movement paths of the two components are often difficult to fine-tune in real time during the process of approaching and joining them. In this case, if there is a positional deviation between the limiting components of the two components, the limiting components cannot accurately align after the components have moved into place. Therefore, before joining the two components, it is necessary to use adjustment fixtures and spend a lot of time adjusting and correcting them to ensure that the limiting components can accurately align after the two components have moved relative to each other, so as to achieve limiting constraints between the two components. This consumes a lot of manpower, material resources, and time, and is extremely inconvenient to use. Utility Model Content

[0004] The main purpose of this application is to propose a limit locking mechanism, which aims to solve the technical problem that existing two-part structures require adjustment fixtures and a lot of time to adjust before assembly to ensure that the limit components on the two-part structure can be accurately aligned, thus incurring high costs and being extremely inconvenient to use.

[0005] To achieve the above objectives, the limiting and locking mechanism proposed in this application includes:

[0006] Limiting components;

[0007] A locking member, which abuts against the limiting member under the action of an external force to fix the limiting member;

[0008] Actuator;

[0009] The mating structure moves along the direction close to the limiting member to drive the actuator to move sequentially to the first posture and the second posture.

[0010] When the actuator is in the first posture, the actuator pushes the locking member to overcome the external force and separate from the limiting member, so that the limiting member is in an active state and docks with the mating structure; when the actuator is in the second posture, the actuator separates from the locking member, so that the locking member abuts against the limiting member again under the action of external force, thereby enabling the limiting member and the mating structure to complete the limiting engagement.

[0011] Optionally, the limiting locking mechanism further includes a fixed seat, the fixed seat having a clearance through hole; the limiting member has a pin portion and a shoulder portion, the first end of the pin portion is connected to the shoulder portion, the pin portion passes through the clearance through hole, and the diameter of the pin portion is smaller than the diameter of the clearance through hole; the locking member presses the shoulder portion against the side of the fixed seat opposite to the mating structure under the action of external force;

[0012] The mating structure has a pin hole portion; during the movement of the mating structure in the direction close to the limiting member, the second end of the pin portion is used to insert into the pin hole portion.

[0013] Optionally, the actuator is configured as a long strip, the middle part of the actuator is rotatably connected to the fixed base, and the first end of the actuator is disposed towards the mating structure;

[0014] As the mating structure approaches the limiting member, it pushes the actuator to rotate sequentially to a first angle and a second angle. When the actuator rotates to the first angle, the second end of the actuator pushes the locking member to move away from the shoulder. When the actuator rotates to the second angle, the second end of the actuator separates from the locking member, so that the locking member is re-pressed onto the shoulder under external force.

[0015] Optionally, the actuator is used to rotate along a first direction under the push of the mating structure; the second end of the actuator is provided with a cam structure, the cam structure taking the rotation center axis of the actuator as the cam shaft, the radial distance of the cam structure gradually increases along a second direction, the second direction being opposite to the first direction;

[0016] The locking member abuts against the contour surface of the cam structure under the action of external force, so as to press the cam structure onto the fixed seat.

[0017] Optionally, the limiting locking mechanism includes at least two actuators, which are spaced apart around the limiting member.

[0018] Optionally, the first end of the actuator is provided with an arc structure; during the process of the mating structure pushing the actuator to rotate, the arc structure abuts and engages with the mating structure.

[0019] Optionally, the fixing seat has a first ear and a second ear that are spaced apart. The surface of the first ear is provided with a first arc-shaped mating part, and the surface of the second ear is provided with a second arc-shaped mating part. A first connecting groove is provided on the side of the first ear facing the second ear, and a second connecting groove is provided on the side of the second ear facing the first ear. The first connecting groove and the second connecting groove are in communication with the outside.

[0020] The actuator is located between the first ear and the second ear. The actuator has a first connecting shaft, a second connecting shaft and a limiting baffle in the middle. The first connecting shaft is rotatably engaged in the first connecting groove, the second connecting shaft is rotatably engaged in the second connecting groove, and the limiting baffle is slidably engaged in the surface of the first arc-shaped mating part and the surface of the second arc-shaped mating part.

[0021] Optionally, the second end of the pin portion is provided with a guide shaft section, the diameter of which gradually decreases in the direction away from the locking member.

[0022] Optionally, the pin hole portion is provided with a guide hole section on the side facing the locking member, and the diameter of the guide hole section gradually increases along the direction close to the locking member.

[0023] Optionally, the limiting locking mechanism further includes a base and an elastic element, the elastic element being connected to the base and the locking element respectively; the elastic element is used to apply an elastic force to the locking element so that the locking element abuts against the limiting element.

[0024] This application also proposes an air vehicle, which includes a land vehicle, an aircraft, and a limiting locking mechanism as described above;

[0025] The limiting locking mechanism has a limiting component, a locking component, and an actuating component mounted on the land vehicle, and a cooperating structure mounted on the aircraft; or, the limiting component, the locking component, and the actuating component are mounted on the aircraft, and the cooperating structure is mounted on the land vehicle.

[0026] The limiting locking mechanism proposed in this application involves a mating structure that synchronously drives an actuator during engagement with the limiting member. This actuator can then push the locking member away from the limiting member, allowing the limiting member to be in an active state. Even if there is a certain positional deviation between the limiting member and the mating structure, once the mating structure contacts the limiting member, the limiting member can move under the influence of the mating structure to a position where it can accurately align with the mating structure. This achieves self-adaptive adjustment of the limiting member, enabling the limiting member and the mating structure to autonomously complete alignment and limiting engagement. After the limiting member and the mating structure complete the limiting engagement, the actuator will synchronously move under the influence of the mating structure to a position where it separates from the locking member. Once the driving force provided by the actuator is lost, the locking member will re-abut against the limiting member under external force to fix the limiting member in place. This maintains the limiting member and the mating structure in their current limiting engagement state. Based on this technical solution, the limiting component and the mating structure can have a certain tolerance. Thus, even if there is a certain positional deviation between the limiting component and the mating structure, the limiting component and the mating structure can successfully complete the limiting fit through adaptive adjustment during the docking process, without having to use adjustment fixtures and spend a lot of time on adjustment and correction before the docking operation begins. This greatly saves manpower, material resources and time costs, and improves the ease of use. Attached Figure Description

[0047] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0048] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0049] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0050] For most two-part structures, the two separate components need to be combined into a single unit under certain operating conditions. For example, in a split-type flying vehicle, the land vehicle and the aircraft are combined; after use, the aircraft needs to be stored in the land vehicle and transported away. During the combination of the two separate components, limiting components are often used to constrain them and prevent relative displacement after combination.

[0051] For heavy, two-part structures such as split-type flying vehicles, the movement paths of the two components are often difficult to fine-tune in real time during the process of approaching and joining them. In this case, if there is a positional deviation between the limiting components of the two components, the limiting components cannot accurately align after the components have moved into place. Therefore, before joining the two components, it is necessary to use adjustment fixtures and spend a lot of time adjusting and correcting them to ensure that the limiting components can accurately align after the two components have moved relative to each other, so as to achieve limiting constraints between the two components. This consumes a lot of manpower, material resources, and time, and is extremely inconvenient to use.

[0052] The researchers of this application discovered that the limiting components on existing two-part structures all adopt rigid structures with extremely low tolerance. When the two structures move into place relative to each other, it is necessary to ensure that the limiting components on one structure are precisely aligned with the limiting components on the other structure so that the two limiting components can be successfully engaged. If the relative positions of the two limiting components are slightly off, they cannot be engaged.

[0053] To address the aforementioned issues, this application proposes a limiting locking mechanism. The limiting components are designed to be movable within a certain range, thus providing a degree of tolerance. This allows for successful mating even if there is a positional deviation between the limiting components, through adaptive adjustment during the docking process. After mating, the limiting components are fixed by appropriate components to ensure they function as limiting constraints.

[0054] Please see Figures 1 to 6 An embodiment of this application provides a limiting locking mechanism, comprising:

[0055] Limiting component 1;

[0056] Locking member 2, under the action of external force, abuts against limiting member 1 to fix limiting member 1;

[0057] Actuator 3;

[0058] The cooperating structure 4 moves along the direction close to the limiting member 1 to drive the actuator 3 to move to the first posture and the second posture in sequence;

[0059] When the actuator 3 is in the first posture, the actuator 3 pushes the locking member 2 to overcome the external force and separate from the limiting member 1, so that the limiting member 1 is in an active state and docks with the mating structure 4; when the actuator 3 is in the second posture, the actuator 3 separates from the locking member 2, so that the locking member 2 abuts against the limiting member 1 again under the action of external force, so that the limiting member 1 and the mating structure 4 complete the limiting engagement.

[0060] In this embodiment, the limiting member 1 and the mating structure 4 refer to the two parts on the limiting assembly used for engagement to form a limiting constraint. Taking a pin-hole engagement as an example, one of the limiting member 1 and the mating structure 4 is a pin structure and the other is a pin hole structure; taking a latch engagement as an example, one of the limiting member 1 and the mating structure 4 is a latching tongue structure and the other is a latching hole structure; taking a snap-fit ​​engagement as an example, one of the limiting member 1 and the mating structure 4 is a claw structure and the other is a slot structure. In practical applications, the limiting member 1 and the mating structure 4 are respectively set on the two structures of the two-part structure. It is only necessary to ensure that the limiting member 1 and the mating structure 4 can engage as the two structures approach each other, thereby achieving the limiting constraint effect between the two structures. More structural forms of the limiting member 1 and the mating structure 4 are not listed here.

[0061] The locking member 2 can be a plate-shaped structure, a block-shaped structure, etc. The locking member 2 can abut against the limiting member 1 under the action of external forces such as gravity, elastic force, and the compressive force of other components, so that the limiting member 1 is in a fixed state.

[0062] The actuator 3 can serve as a transmission structure, converting the movement of the mating structure 4 near the limiting member 1 into other forms of motion, such as rotation around its central axis, linear movement along other paths, or a combination of rotation and linear movement. Specifically, during the transition from the first posture to the second posture, the actuator 3 should simultaneously possess motion components in two directions. One direction's motion component is directed in the opposite direction to the external force acting on the locking member 2, pushing the locking member 2 against the external force and moving it in the opposite direction to separate the locking member 2 from the limiting member 1. The other direction's motion component is a lateral deviation from the locking member 2, allowing the actuator 3 to gradually deviate from the locking member 2 laterally, ultimately separating the actuator 3 from the locking member 2. At this point, the actuator 3 no longer exerts a pushing effect on the locking member 2, and the locking member 2 will re-abut against the limiting member 1 under the action of the external force.

[0063] Based on the above settings, the specific process by which the limit locking mechanism completes the limit engagement is as follows:

[0064] In the initial state where the limiting member 1 and the mating structure 4 are not engaged, the locking member 2 abuts against the limiting member 1 under the action of external force, so that the limiting member 1 is in a fixed state; after the engagement operation begins, the mating structure 4 moves in the direction close to the limiting member 1. When the mating structure 4 contacts the actuator 3, the actuator 3 can convert the movement of the mating structure 4 into other forms of movement, so that the actuator 3 can move sequentially to the first posture and the second posture along the preset path under the drive of the mating structure 4; when the actuator 3 is in the first posture, the actuator 3 contacts the locking member 2 and pushes... The locking member 2 moves in the opposite direction of the external force, separating it from the limiting member 1. This allows the limiting member 1 to be movable without being subjected to the abutting force of the locking member 2. At this time, the mating structure 4 also moves synchronously to the position where it mates with the limiting member 1. Because the limiting member 1 is movable, even if there is a certain positional deviation between the limiting member 1 and the mating structure 4, once the mating structure 4 contacts the limiting member 1, the limiting member 1 can still move under the action of the mating structure 4 to a position where it can accurately mate with the mating structure 4, thus achieving [the desired result]. The self-adaptive adjustment of the limiting member 1 enables the limiting member 1 and the mating structure 4 to autonomously complete their alignment. During the process of the actuator 3 moving from the first posture to the second posture driven by the mating structure 4, the actuator 3 will continuously push the locking member 2 in the opposite direction of the external force, and will also move laterally away from the locking member 2. Simultaneously, the mating structure 4 will further limit the alignment of the limiting member 1 along a predetermined direction of movement. When the actuator 3 moves to the second posture under the drive of the mating structure 4, the mating structure 4 and the limiting member... When the limiting engagement is completed between the two parts, the actuator 3 also separates from the locking part 2. After losing the pushing force provided by the actuator 3, the locking part 2 will abut against the limiting part 1 again under the action of external force to fix the limiting part 1. Thus, the limiting part 1 and the mating structure 4 can be kept in the current limiting engagement state. In the application scenario where the limiting part 1 and the mating structure 4 are respectively set on the two structures of the two-part structure, the limiting constraint between the two structures has been achieved through the limiting engagement between the limiting part 1 and the mating structure 4.

[0065] Therefore, the limiting locking mechanism provided in this embodiment, during the engagement of the cooperating structure 4 with the limiting member 1, will synchronously drive the actuator 3 to move. Thus, the actuator 3 can push the locking member 2 to separate from the limiting member 1, making the limiting member 1 in an active state. In this way, even if there is a certain positional deviation between the limiting member 1 and the cooperating structure 4, when the cooperating structure 4 contacts the limiting member 1, the limiting member 1 can also move under the drive of the cooperating structure 4 to a position that can accurately engage with the cooperating structure 4. That is, the limiting member 1 achieves adaptive adjustment, so that the limiting member 1 and the cooperating structure 4 can autonomously complete the alignment and limiting engagement. After the limiting member 1 and the cooperating structure 4 complete the limiting engagement, the actuator 3 will synchronously move under the drive of the cooperating structure 4 to a position that is separated from the locking member 2. After losing the pushing force provided by the actuator 3, the locking member 2 will abut against the limiting member 1 again under the action of external force to fix the limiting member 1. Thus, the limiting member 1 and the cooperating structure 4 that have completed the limiting engagement can be maintained in the current limiting engagement state. Based on the solution of this embodiment, the limiting member 1 and the mating structure 4 can have a certain tolerance. Thus, even if there is a certain positional deviation between the limiting member 1 and the mating structure 4, the limiting member 1 and the mating structure 4 can still complete the limiting fit smoothly through adaptive adjustment during the docking process, without having to use adjustment fixtures and spend a lot of time adjusting and correcting before the docking operation begins. This greatly saves manpower, material resources and time costs, and improves the ease of use.

[0066] Optionally, refer to Figures 1 to 6 The limiting and locking mechanism also includes a fixed base 5, which has a clearance through hole 51; the limiting member 1 has a pin portion 11 and a shoulder portion 12, the first end of the pin portion 11 is connected to the shoulder portion 12, the pin portion 11 passes through the clearance through hole 51, and the diameter of the pin portion 11 is smaller than the diameter of the clearance through hole 51; the locking member 2 presses the shoulder portion 12 against the side of the fixed base 5 facing away from the mating structure 4 under the action of external force;

[0067] The mating structure 4 has a pin hole portion 41; during the movement of the mating structure 4 in the direction close to the limiting member 1, the second end of the pin shaft portion 11 is used to insert into the pin hole portion 41.

[0068] In this embodiment, the limiting member 1 and the mating structure 4 adopt a pin-hole mating limiting form. After the pin shaft portion 11 of the limiting member 1 and the pin hole portion 41 of the mating structure 4 come into contact with each other, they are more easily driven to slide relative to each other, thereby completing the alignment of the pin shaft portion 11 and the pin hole portion 41 more smoothly. The diameter of the shoulder portion 12 of the limiting member 1 is larger than the diameter of the clearance through hole 51, so that the abutment of the shoulder portion 12 and the fixed seat 5 can form an axial limiting effect on the pin shaft portion 11; the diameter of the pin shaft portion 11 is smaller than the diameter of the clearance through hole 51, so that the pin shaft portion 11 has a certain amount of movement margin in the radial direction within the clearance through hole 51, so that the pin shaft portion 11 can move relative to the fixed seat 5 during the subsequent docking with the pin hole portion 41 to complete adaptive adjustment. The fixing seat 5 provides a support base for the shoulder 12, so that the locking member 2 can press the shoulder 12 against the side of the fixing seat 5 facing away from the mating structure 4 under the action of external force, thereby fixing the limiting member 1.

[0069] In the actual limiting and mating process, the shoulder 12 is initially clamped between the locking member 2 and the fixed seat 5, and the limiting member 1 is in a fixed state; after the mating operation begins, the pin hole 41 moves towards the mating pin shaft 11 as the mating structure 4 moves. When the mating structure 4 contacts the actuator 3, the actuator 3 can convert the movement of the mating structure 4 into other forms of movement, so that the actuator 3 can move sequentially to the first posture and the second posture along the preset path under the drive of the mating structure 4; when the actuator 3 is at In the first posture, the actuator 3 contacts the locking member 2 and pushes the locking member 2 to separate from the shoulder 12, so that the limiting member 1 is radially movable without being pressed by the locking member 2. At this time, the pin hole 41 also moves synchronously to the position to mate with the pin shaft 11. Since the limiting member 1 is in a movable state, even if there is a certain coaxiality deviation between the pin shaft 11 and the pin hole 41, the pin shaft 11 can still be driven by the pin hole 41 after contacting the pin shaft 11. The pin shaft 11 is moved downwards to a position coaxial with the pin hole 41, achieving adaptive adjustment. During the movement of the actuator 3 from the first posture to the second posture, driven by the mating structure 4, the actuator 3 continuously pushes the locking member 2 away from the shoulder 12, allowing the limiting member 1 to have a certain axial margin of movement, thus providing more adjustment space for the pin shaft 11 in the axial direction. Simultaneously, the actuator 3 moves laterally away from the locking member 2, and the pin shaft 11 moves with the mating structure 4. The actuator moves and continuously inserts into the pin hole 41; when the actuator 3 moves to the second posture under the drive of the mating structure 4, the pin shaft 11 is fully inserted into the pin hole 41, and the actuator 3 is also separated from the locking member 2 at this time. After losing the pushing force provided by the actuator 3, the locking member 2 will press the shoulder 12 back onto the side of the fixed seat 5 facing away from the mating structure 4 under the action of external force to fix the limiting member 1, so as to keep the pin shaft 11 and the pin hole 41 in the current limiting engagement state after the insertion engagement is completed.

[0070] Optionally, refer to Figures 1 to 6 The actuator 3 is configured as a long strip, and the middle part of the actuator 3 is rotatably connected to the fixed base 5. The first end of the actuator 3 is set towards the mating structure 4.

[0071] As the cooperating structure 4 approaches the limiting member 1, it pushes the actuator 3 to rotate sequentially to the first angle and the second angle. When the actuator 3 rotates to the first angle, the second end of the actuator 3 pushes the locking member 2 to move away from the shaft shoulder 12. When the actuator 3 rotates to the second angle, the second end of the actuator 3 separates from the locking member 2, so that the locking member 2 is pressed back onto the shaft shoulder 12 under the action of external force.

[0072] Specifically, the middle part of the actuator 3 can be rotatably connected to the fixed base 5 by means of a hinge, or the actuator 3 can be rotated around a preset fulcrum on the fixed base 5 by means of other limiting structures in the case of non-hinged connection, which is not limited here.

[0073] In the actual process of limit matching, refer to Figure 3 In the initial state, the shoulder 12 is clamped between the locking member 2 and the fixed seat 5, and the limiting member 1 is in the position as follows. Figure 1 and Figure 2 The fixed state is shown; after the engagement operation begins, the pin hole portion 41 moves axially towards the pin shaft portion 11 as the mating structure 4 moves. When the mating structure 4 contacts the first end of the actuator 3, as shown... Figure 4 As shown, the actuator 3 rotates to the first angle under the push of the mating structure 4. At this time, the second end of the actuator 3 contacts the locking member 2. The second end of the actuator 3 can apply a pushing force to the locking member 2 away from the shoulder 12, causing the locking member 2 to separate from the shoulder 12. This allows the limiting member 1 to be in a radially movable state without being subjected to the pressing force of the locking member 2. At this time, the pin hole 41 also moves synchronously to the position where it mates with the pin shaft 11. Since the limiting member 1 is in a movable state, even if there is a certain coaxiality deviation between the pin shaft 11 and the pin hole 41, when the pin shaft 11 contacts the pin hole 41, The pin portion 11 can also move to a position coaxial with the pin hole portion 41 under the drive of the pin hole portion 41, realizing the self-adaptive adjustment of the pin portion 11; during the process of the actuator 3 being pushed by the mating structure 4 and rotating from the first angle to the second angle, the second end of the actuator 3 will continuously push the locking member 2 away from the shoulder portion 12, so that the limiting member 1 also has a certain amount of axial movement margin, thereby providing more adjustment space for the pin portion 11 in the axial direction; on the other hand, the second end of the actuator 3 will rotate laterally away from the locking member 2, and at the same time, the pin portion 11 will continuously insert into the pin hole portion 41 as the mating structure 4 moves; Figure 5 and Figure 6 As shown, when the actuator 3 rotates to the second angle under the drive of the mating structure 4, the pin shaft portion 11 is fully inserted into the pin hole portion 41. At this time, the second end of the actuator 3 also rotates to the outside of the locking member 2 and separates from the locking member 2. After losing the pushing force provided by the actuator 3, the locking member 2 will press the shoulder portion 12 back onto the side of the fixed seat 5 facing away from the mating structure 4 under the action of external force to fix the limiting member 1. Thus, the pin shaft portion 11 and the pin hole portion 41 that have completed the insertion and mating can be kept in the current limiting and mating state.

[0074] In this embodiment, the actuator 3 is configured to rotate relative to the fixed base 5. This can convert the linear movement of the mating structure 4 along the pin hole insertion direction into rotational motion. By utilizing the properties of rotational motion, on the one hand, the actuator 3 can push the locking member 2 to separate from the limiting member 1, and on the other hand, it can ensure that the actuator 3 separates from the locking member 2 after rotating a certain angle, so that the locking member 2 is pressed back onto the limiting member 1 under the action of external force. This ensures that the entire limiting and mating process can proceed normally in the preset manner.

[0075] Optionally, refer to Figures 1 to 6 The actuator 3 is used to rotate in the first direction under the push of the mating structure 4; the second end of the actuator 3 is provided with a cam structure 31, the cam structure 31 takes the rotation center axis of the actuator 3 as the cam shaft, and the radial distance of the cam structure 31 gradually increases in the second direction, which is opposite to the first direction.

[0076] The locking element 2 abuts against the contour surface of the cam structure 31 under the action of external force, so as to press the cam structure 31 onto the fixed seat 5.

[0077] In this embodiment, the cam structure 31 can be a complete cam with a central angle of 180° or a partial cam with a central angle of less than 180°. When the cam structure 31 is a partial cam with a central angle of less than 180°, the cam structure 31 can be regarded as a fan-shaped structure with different radii at various points.

[0078] By setting the cam structure 31, before the limiting member 1 and the mating structure 4 perform the limiting engagement operation, the locking member 2 can simultaneously press the limiting member 1 and... Figure 3 The portion of the profile surface with a small radial distance pressed against the cam structure 31, as shown, can also maintain the stability of the actuator 3's posture by pressing against the cam structure 31 through the locking member 2, thus preventing the actuator 3 from rotating autonomously without restriction; preferably, when the cam structure 31 is set as a local cam with a central angle of less than 180°, the cam structure 31 can be as follows before the limiting engagement operation. Figure 3 It is shown that it is clamped between the locking member 2 and the fixed base 5 on the side opposite to the mating structure 4.

[0079] During the process of the actuator 3 being rotated in the first direction by the cooperating structure 4, the radial distance of the cam structure 31 gradually increases in the second direction. Therefore, the profile of the cam structure 31 will push the locking member 2 to move away from the limiting member 1 at a relatively uniform speed as the actuator 3 rotates, thus ensuring the smoothness of the movement of the locking member 2.

[0080] Optionally, refer to Figures 1 to 6 The limiting locking mechanism includes at least two actuators 3, which are arranged at intervals around the limiting member 1.

[0081] By arranging at least two actuators 3 at intervals around the limiting member 1, when the cooperating structure 4 pushes at least two actuators 3 to rotate, the actuators 3 can apply a pushing force to the locking member 2 at multiple positions around the limiting member 1, thereby ensuring that the locking member 2 is pushed to a state where it is completely separated from the limiting member 1, avoiding the situation where part of the locking member 2 is separated from the limiting member 1 while part of the locking member 2 remains in contact with the limiting member 1.

[0082] Preferably, the actuator 3 is as follows Figure 1 , Figure 2 and Figure 6 The arrangement shown is two units, evenly arranged around the limiting member 1.

[0083] Optionally, refer to Figures 1 to 6 The first end of the actuator 3 is provided with an arc structure 32; during the process of the mating structure 4 pushing the actuator 3 to rotate, the arc structure 32 abuts and engages with the mating structure 4.

[0084] Since the first end of the actuator 3 will slide on the surface of the mating structure 4 during the process of the mating structure 4 pushing the actuator 3 to rotate, by setting the arc structure 32 at the first end of the actuator 3, the smoothness and stability of the first end of the actuator 3 sliding on the surface of the mating structure 4 can be improved, ensuring that the actuator 3 can rotate smoothly under the push of the mating structure 4, and at the same time, it can also avoid the first end of the actuator 3 from causing scratch damage to the surface of the mating structure 4 to a certain extent.

[0085] Optionally, refer to Figures 1 to 8 The fixing base 5 has a first ear 52 and a second ear 53 spaced apart. The surface of the first ear 52 is provided with a first arc fitting part 521, and the surface of the second ear 53 is provided with a second arc fitting part 531. A first connecting groove (not shown in the figure) is opened on the side of the first ear 52 facing the second ear 53, and a second connecting groove 532 is opened on the side of the second ear 53 facing the first ear 52. The first connecting groove and the second connecting groove 532 are in communication with the outside.

[0086] The actuator 3 is located between the first ear portion 52 and the second ear portion 53. The actuator 3 has a first connecting shaft 33, a second connecting shaft 34 and a limiting baffle 35 in the middle. The first connecting shaft 33 is rotatably engaged in the first connecting groove, the second connecting shaft 34 is rotatably engaged in the second connecting groove 532, and the limiting baffle 35 is slidably engaged in the surface of the first arc-shaped mating portion 521 and the surface of the second arc-shaped mating portion 531.

[0087] Illustrationly, the first ear portion 52 and the second ear portion 53 are both arc-shaped on the side facing the mating structure 4, so as to form the first arc mating portion 521 and the second arc mating portion 531 respectively; the first end of the first connecting groove communicates with the outside through the first opening on the first ear portion 52, and the second end of the first connecting groove extends into the interior of the area covered by the first arc mating portion 521; the first end of the second connecting groove 532 communicates with the outside through the second opening on the second ear portion 53, and the second end of the second connecting groove 532 extends into the interior of the area covered by the second arc mating portion 531.

[0088] The first connecting shaft 33 and the second connecting shaft 34 are located on opposite sides of the middle of the actuator 3. The limiting baffle 35 is spaced apart from the first connecting shaft 33 and the second connecting shaft 34. The distance between the limiting baffle 35 and the first connecting shaft 33 corresponds to the distance between the second end of the first connecting groove and the surface of the first arc mating part 521. The distance between the limiting baffle 35 and the second connecting shaft 34 corresponds to the distance between the second end of the second connecting groove 532 and the surface of the second arc mating part 531.

[0089] In the actual assembly process, the actuator 3 can be placed between the first ear 52 and the second ear 53, so that the first connecting shaft 33 enters the first connecting groove through the first opening and the second connecting shaft 34 enters the second connecting groove 532 through the second opening. Then, by moving the actuator 3, the first connecting shaft 33 and the second connecting shaft 34 are moved to the second end of the first connecting groove and the second end of the second connecting groove 532, respectively, and the limiting baffle 35 is moved to the position of the first arc mating part 521 and the second arc mating part 531. At this time, the first connecting shaft 33 is rotatably mated to the second end of the first connecting groove, and the second connecting shaft 34 is rotatably mated to the second end of the second connecting groove 532. The limiting baffle 35 can slide along the arc path relative to the surface of the first arc mating part 521 and the surface of the second arc mating part 531, thus realizing the rotational mating between the actuator 3 and the fixed seat 5.

[0090] This embodiment achieves the assembly between the actuator 3 and the fixed seat 5 in a convenient and easy manner. The actuator 3 is rotated and limited from the inside by the rotational engagement between the first connecting shaft 33 and the first connecting groove, and the rotational engagement between the second connecting shaft 34 and the second connecting groove 532. The actuator 3 is rotated and limited from the outside by the sliding engagement between the limiting baffle 35 and the surfaces of the first arc engagement part 521 and the second arc engagement part 531. This achieves a stable rotational engagement between the actuator 3 and the fixed seat 5 and can prevent the actuator 3 from detaching from the fixed seat 5 during rotation to a certain extent.

[0091] Optionally, refer to Figures 1 to 6The second end of the pin portion 11 is provided with a guide shaft section 111, and the diameter of the guide shaft section 111 gradually decreases in the direction away from the locking member 2.

[0092] Optionally, refer to Figures 1 to 6 The pin hole 41 is provided with a guide hole section 411 on the side facing the locking member 2, and the diameter of the guide hole section 411 gradually increases along the direction close to the locking member 2.

[0093] Specifically, by providing guide shaft section 111 and / or guide hole section 411, when the limiting member 1 contacts the mating structure 4, the guiding effect of guide shaft section 111 and / or guide hole section 411 can guide the pin shaft part 11 in the active state to move to the position opposite to the pin hole part 41, and further guide the pin shaft part 11 to smoothly insert into the pin hole part 41, thereby improving the smoothness and stability of the pin shaft part 11 and the pin hole part 41 when they are mated, and further improving the tolerance of the limiting member 1 and the mating structure 4, so that the pin shaft part 11 and the pin hole part 41 can still be mated even when there is a large positional deviation.

[0094] Optionally, refer to Figures 1 to 6 The limiting locking mechanism also includes a base 6 and an elastic element 7. The elastic element 7 is connected to the base 6 and the locking element 2 respectively. The elastic element 7 is used to apply an elastic force to the locking element 2 so that the locking element 2 abuts against the limiting element 1.

[0095] Specifically, the fixed base 5 can be fixed to the base 6 by means of threaded connection, etc. Taking the elastic element 7 as an example, one end of the elastic element 7 is connected to the base 6, and the other end of the elastic element 7 is connected to the locking element 2. The elastic element 7 is in a compressed state, so that the elastic element 7 can apply an elastic force toward the limiting element 1 to the locking element 2, so that the limiting element 1 is firmly pressed onto the limiting element 1.

[0096] This embodiment, by incorporating the elastic element 7, can provide external force to the locking element 2 from different directions, thereby achieving the pressing and fixing effect of the locking element 2 on the limiting element 1 without restricting the relative placement position and angle between the locking element 2 and the limiting element 1, thus improving the flexibility of use. Furthermore, elastic elements 7 with different elastic coefficients can be easily replaced according to actual needs to meet different pressing force requirements, thereby improving the applicability of this limiting and locking mechanism.

[0097] Please see Figures 1 to 10 This application also provides an air vehicle, which includes a land vehicle 1000, an aircraft 2000, and the limiting locking mechanism in any of the above embodiments;

[0098] The limiting component 1, locking component 2, and actuating component 3 of the limiting locking mechanism are installed on the land vehicle 1000, and the cooperating structure 4 of the limiting locking mechanism is installed on the aircraft 2000; or, the limiting component 1, locking component 2, and actuating component 3 are installed on the aircraft 2000, and the cooperating structure 4 is installed on the land vehicle 1000.

[0099] In this embodiment, the flying vehicle includes, but is not limited to, a split-type flying car; such as Figure 10 As shown, after use, the aircraft 2000 of the flying vehicle needs to be stored in the land vehicle 1000 of the flying vehicle and transported away by the land vehicle 1000. During the process of storing the aircraft 2000 in the land vehicle 1000, a limiting locking mechanism installed on the land vehicle 1000 and the aircraft 2000 is used to limit and constrain the two to prevent relative displacement between the aircraft 2000 and the land vehicle 1000 after they are combined.

[0100] For the specific configuration of the limit locking mechanism, please refer to the above embodiment. Taking an example where the limit locking mechanism's limit member 1, locking member 2, and actuator 3 are installed on the land vehicle 1000, and the matching structure 4 is installed on the aircraft 2000, the specific process of the limit locking mechanism completing the limit engagement during the combination of the land vehicle 1000 and the aircraft 2000 is explained below:

[0101] In the initial state, the aircraft 2000 is separated from the land vehicle 1000. At this time, the limiting member 1 and the mating structure 4 are not engaged. The locking member 2 abuts against the limiting member 1 under the action of external force, so that the limiting member 1 is in a fixed state. When the aircraft 2000 moves into the land vehicle 1000 to start the engagement operation, the mating structure 4 will move towards the limiting member 1 as the aircraft 2000 moves. When the mating structure 4 contacts the actuator 3, the actuator 3 can convert the movement of the mating structure 4 into other forms of movement, so that the actuator 3 can move along a preset path under the drive of the mating structure 4. The path moves sequentially to the first posture and the second posture. When the actuator 3 is in the first posture, the actuator 3 contacts the locking member 2 and pushes the locking member 2 to move in the opposite direction of the external force, causing the locking member 2 to separate from the limiting member 1. This allows the limiting member 1 to be in a movable state without being subjected to the abutting force of the locking member 2. At this time, the mating structure 4 also moves synchronously to the position where it docks with the limiting member 1. Since the limiting member 1 is in a movable state, even if there is a certain positional deviation between the limiting member 1 and the mating structure 4, the limiting member 1 can still move within the mating structure after the mating structure 4 contacts the limiting member 1. Driven by 4, it moves to a position where it can accurately align with the mating structure 4, thus achieving the adaptive adjustment of the limiting component 1, enabling the limiting component 1 and the mating structure 4 to autonomously complete their alignment. During the process of the actuator 3 moving from the first posture to the second posture driven by the mating structure 4, the actuator 3 will continuously push the locking component 2 in the opposite direction of the external force, and will also move laterally away from the locking component 2. Simultaneously, the mating structure 4 will continue to perform further limiting engagement with the aligned limiting component 1 as the aircraft 2000 moves. When the aircraft 2000 moves to the land vehicle 100... When the actuator 3 is in the preset position inside the 0, it will move to the second posture under the drive of the cooperating structure 4. At this time, the cooperating structure 4 and the limiting member 1 complete the limiting engagement. The actuator 3 also separates from the locking member 2. After losing the pushing force provided by the actuator 3, the locking member 2 will abut against the limiting member 1 again under the action of external force to fix the limiting member 1. Thus, the limiting member 1 and the cooperating structure 4 can be kept in the current limiting engagement state. In this way, the limiting constraint between the aircraft 2000 and the land vehicle 1000 is realized through the limiting engagement between the limiting member 1 and the cooperating structure 4.

[0102] Since this flying vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments. That is, during the engagement of the mating structure 4 with the limiting member 1, the actuator 3 will be driven to move synchronously. Thus, the actuator 3 can push the locking member 2 to separate from the limiting member 1, so that the limiting member 1 is in an active state. In this way, even if there is a certain positional deviation between the limiting member 1 and the mating structure 4, when the mating structure 4 contacts the limiting member 1, the limiting member 1 can also move under the drive of the mating structure 4 to be able to engage with the locking member 2. The precise alignment of the mating structure 4 enables the adaptive adjustment of the limiting member 1, allowing the limiting member 1 and the mating structure 4 to autonomously complete alignment and limiting engagement. After the limiting member 1 and the mating structure 4 complete the limiting engagement, the actuator 3 will move synchronously to the position separated from the locking member 2 under the drive of the mating structure 4. After losing the pushing force provided by the actuator 3, the locking member 2 will re-abut against the limiting member 1 under the action of external force to fix the limiting member 1, thereby maintaining the limiting member 1 and the mating structure 4 in the current limiting engagement state. Based on this technical solution, the limiting component 1 and the mating structure 4 can have a certain tolerance. Thus, even if there is a certain positional deviation between the limiting component 1 and the mating structure 4, the limiting component 1 and the mating structure 4 can successfully complete the limiting fit through adaptive adjustment during the docking process, without having to use large adjustment fixtures and spend a lot of time on adjustment and correction before the docking operation of the aircraft 2000 and the land vehicle 1000 begins. This greatly saves manpower, material resources and time costs, and improves ease of use.
