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 adjust in real time as needed 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, thereby achieving 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 limiting 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 limiting 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] Mounting base;

[0007] A limiting element is movably connected to the mounting base;

[0008] A mating structure, wherein the mating structure is used to engage with the limiting member in the active state;

[0009] A locking element is connected to the limiting element;

[0010] A driving assembly is connected to the locking member; the driving assembly is used to drive the locking member to abut against the mounting base to fix the limiting member relative to the mounting base.

[0011] Optionally, the limiting member has a pin portion, and the mating structure has a pin hole portion; the mating structure is used to move in a direction close to the limiting member so that the pin portion is inserted into the pin hole portion.

[0012] Optionally, the limiting member further has a shoulder portion and a threaded locking section, the first end of the threaded locking section being connected to the shoulder portion, and the second end of the threaded locking section being connected to the pin portion;

[0013] The mounting base has a first connecting through hole, and the threaded locking section passes through the first connecting through hole. The diameter of the first connecting through hole is larger than the diameter of the threaded locking section. The shoulder portion is used to abut against the side of the mounting base opposite to the mating structure.

[0014] The locking element includes a locking nut, which is threadedly connected to the threaded locking section; the driving assembly is used to drive the locking nut to move axially relative to the threaded locking section, so that the locking nut is pressed against the mounting base on the side facing the mating structure.

[0015] Optionally, the locking nut has a gear structure on its outer side; the drive assembly includes a drive device and a transmission gear assembly, the output end of the drive device is connected to the transmission gear assembly, and the transmission gear assembly meshes with the gear structure.

[0016] Optionally, the transmission gear assembly includes an output gear and an intermediate gear; the output gear is connected to the output end of the drive device, and the intermediate gear meshes with the output gear and the gear structure respectively.

[0017] Optionally, the end of the pin shaft portion used for insertion into the pin hole portion is provided with a guide shaft section, the diameter of which gradually decreases along the moving direction of the pin shaft portion relative to the pin hole portion.

[0018] Optionally, the pin hole portion has a guide hole section on the side for insertion of the pin shaft portion, and the diameter of the guide hole section gradually increases along the moving direction of the pin hole portion relative to the pin shaft portion.

[0019] Optionally, the limiting locking mechanism further includes a support base, which is movably connected to the mounting base, the limiting member is connected to the support base, and the driving component is disposed on the support base.

[0020] Optionally, the limiting locking mechanism further includes a support base, which is movably connected to the side of the mounting base facing the mating structure. The support base has a second connecting through hole, and the threaded locking section passes through and engages in the second connecting through hole. The driving component is disposed on the support base.

[0021] The locking nut is used to press against the side of the support seat facing away from the mounting seat under the drive of the drive assembly, so as to fix the support seat and the mounting seat relative to each other.

[0022] Optionally, the mounting base has a third connecting through hole, and the support base has a fourth connecting through hole;

[0023] The limiting locking mechanism further includes a locking pin assembly, which has a first flange portion, a pin body segment, and a second flange portion arranged in sequence. The pin body segment is axially movable through the third connecting through hole and the fourth connecting through hole. The diameter of the pin body segment is smaller than the diameter of the third connecting through hole and / or the diameter of the fourth connecting through hole. The first flange portion is used to abut against the side of the mounting base opposite to the support base, and the second flange portion is used to abut against the side of the support base opposite to the mounting base.

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

[0026] The limiting locking mechanism proposed in this application allows the limiting component to be in an active state relative to the mounting base in its initial state. Even if there is a certain positional deviation between the limiting component and the mating structure, once the mating structure contacts the limiting component, the limiting component can move under the influence of the mating structure to a position where it can accurately align with the mating structure. This achieves self-adjustment of the limiting component, enabling it and the mating structure to autonomously complete alignment and limiting engagement. After the limiting component and the mating structure complete the limiting engagement, the drive component can drive the locking component to abut against the mounting base, fixing the limiting component and the mounting base relative to each other. This maintains the limiting component and the mating structure in their current limiting engagement state. Based on this technical solution, a certain tolerance can be achieved between the limiting component and the mating structure. Thus, even if there is a certain positional deviation between the limiting component and the mating structure, they can smoothly complete the limiting engagement through self-adjustment during the docking process, without the need for adjustment fixtures and the significant time spent on adjustment and correction before the docking operation begins. This greatly saves manpower, material resources, and time costs, and improves ease of use. Attached Figure Description

[0042] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] For heavy, two-part structures such as split-type flying vehicles, the movement paths of the two components are often difficult to adjust in real time as needed 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, thereby achieving limiting constraints between the two components. This consumes a lot of manpower, material resources, and time, and is extremely inconvenient to use.

[0048] 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.

[0049] 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 corresponding driving components to ensure that they function as limiting constraints.

[0050] Please see Figure 1 and Figure 2 An embodiment of this application provides a limiting locking mechanism, comprising:

[0051] Mounting base 1;

[0052] The limiting component 2 is movably connected to the mounting base 1;

[0053] The mating structure 3 is used to engage with the limiting member 2 in the active state.

[0054] Locking component 4 is connected to limiting component 2;

[0055] Drive assembly 5 is connected to locking member 4; drive assembly 5 is used to drive locking member 4 to abut against mounting base 1 so as to fix limiting member 2 relative to mounting base 1.

[0056] In this embodiment, the limiting member 2 and the mating structure 3 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 2 and the mating structure 3 is a pin structure and the other is a pin hole structure; taking a latch engagement as an example, one of the limiting member 2 and the mating structure 3 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 2 and the mating structure 3 is a claw structure and the other is a slot structure. In practical applications, the limiting member 2 is installed on one of the two structures via the mounting base 1, and the mating structure 3 is set on the other structure. It is sufficient to ensure that the limiting member 2 and the mating structure 3 can engage as the two structures approach each other, thereby achieving the limiting constraint between the two structures. More structural forms of the limiting member 2 and the mating structure 3 are not listed here.

[0057] The limiting member 2 can be connected to the mounting base 1 by means of a flexible hinge, a riveting member, a guide rail slider assembly, or other limiting components, so that the limiting member 2 has a certain degree of freedom of movement relative to the mounting base 1 in the corresponding direction, while avoiding complete separation of the limiting member 2 from the mounting base 1.

[0058] The locking element 4 can be a threaded fastening structure, a snap-fit ​​structure, a pin structure, a press-fit structure, etc. The locking element 4 can be fixedly connected to the limiting element 2 or movably connected to the limiting element 2. The driving assembly 5 can include a power device such as a motor, cylinder, or hydraulic cylinder, and a matching transmission mechanism. The driving assembly 5 can drive the locking element 4 to abut against the mounting base 1, so as to achieve relative fixation between the limiting element 2 and the mounting base 1 by utilizing the connection relationship between the limiting element 2, the locking element 4, and the mounting base 1. Specifically, when the locking member 4 is a threaded fastener threaded to the limiting member 2, the driving component 5 can drive the locking member 4 to screw onto the limiting member 2 and press it against the mounting base 1; when the locking member 4 is a snap-fit ​​structure installed on the limiting member 2, the driving component 5 can drive the locking member 4 to snap onto the mounting base 1; when the locking member 4 is a pin structure set on the limiting member 2, the driving component 5 can drive the locking member 4 to insert and cooperate with the mounting base 1; based on the above methods, the relative fixation between the limiting member 2 and the mounting base 1 can be achieved by active driving. In practical applications, the settings can be flexibly adjusted according to the specific situation such as the positional relationship of each component, which will not be listed here.

[0059] Based on the above settings, the specific process by which the limit locking mechanism completes the limit engagement is as follows:

[0060] In the initial state where the limiting member 2 and the mating structure 3 are not engaged, the locking member 4 is not in contact with the mounting base 1, and the limiting member 2 is in a movable state relative to the mounting base 1. After the engagement operation begins, the mating structure 3 moves towards the limiting member 2. When the mating structure 3 moves to contact the limiting member 2, since the limiting member 2 is in a movable state, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, the limiting member 2 can move to a position that can accurately engage with the mating structure 3 under the action of the mating structure 3, thus realizing the adaptive adjustment of the limiting member 2. This allows the limiting member 2 and the mating structure 3 to autonomously complete their alignment. After the mating structure 3 and the limiting member 2 complete their limiting engagement, the driving component 5 can drive the locking member 4 to abut against the mounting base 1 to fix the limiting member 2 and the mounting base 1 relative to each other, thereby maintaining the limiting member 2 and the mating structure 3 in their current limiting engagement state. In the application scenario where the limiting member 2 and the mating structure 3 are respectively set on the two structures of the two-part structure, the limiting constraint between the two structures is achieved through the limiting engagement of the limiting member 2 and the mating structure 3.

[0061] It should be noted that after the mating structure 3 and the limiting member 2 have completed the limiting engagement, the drive component 5 can be manually operated to drive the locking member 4 to abut against the mounting base 1, or the drive component 5 can be automatically triggered to drive the locking member 4 to abut against the mounting base 1. Specifically, for the automatic triggering method, corresponding sensors can be installed at the limiting member 2 and / or the mating structure 3. When the sensor detects that the mating structure 3 and the limiting member 2 have completed the limiting engagement, the sensor sends a corresponding electrical signal to the main control module, thereby triggering the main control module to send a drive signal to the drive component 5, thus achieving the action of driving the locking member 4 to abut against the mounting base 1 via the drive component 5.

[0062] Therefore, in the limiting locking mechanism provided in this embodiment, the limiting member 2 is in an active state relative to the mounting base 1 in the initial state. Thus, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, when the mating structure 3 contacts the limiting member 2, the limiting member 2 can move under the drive of the mating structure 3 to a position that can accurately align with the mating structure 3. This achieves the adaptive adjustment of the limiting member 2, enabling the limiting member 2 and the mating structure 3 to autonomously complete alignment and limiting engagement. After the limiting member 2 and the mating structure 3 complete the limiting engagement, the driving component 5 can drive the locking member 4 to abut against the mounting base 1 to fix the limiting member 2 and the mounting base 1 relative to each other, thereby maintaining the limiting member 2 and the mating structure 3 in the current limiting engagement state. Based on the solution of this embodiment, the limiting member 2 and the mating structure 3 can have a certain tolerance. Thus, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, the limiting member 2 and the mating structure 3 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.

[0063] Optionally, refer to Figure 1 and Figure 2 The limiting member 2 has a pin shaft portion 21, and the mating structure 3 has a pin hole portion 31; the mating structure 3 is used to move in a direction close to the limiting member 2 so that the pin shaft portion 21 is inserted into the pin hole portion 31.

[0064] In this embodiment, the limiting member 2 and the mating structure 3 adopt a pin hole mating limiting form. After the pin shaft part 21 of the limiting member 2 and the pin hole part 31 of the mating structure 3 come into contact with each other, they are more easily driven to slide relative to each other, so that the alignment of the pin shaft part 21 and the pin hole part 31 can be completed more smoothly.

[0065] Optionally, refer to Figure 1 and Figure 2 The limiting member 2 also has a shoulder 22 and a threaded locking section 23. The first end of the threaded locking section 23 is connected to the shoulder 22, and the second end of the threaded locking section 23 is connected to the pin 21.

[0066] The mounting base 1 has a first connecting through hole 11, and a threaded locking section 23 passes through the first connecting through hole 11. The diameter of the first connecting through hole 11 is larger than the diameter of the threaded locking section 23. The shoulder 22 is used to abut against the side of the mounting base 1 that is opposite to the mating structure 3.

[0067] The locking component 4 includes a locking nut 41, which is threadedly connected to the threaded locking section 23; the driving component 5 is used to drive the locking nut 41 to move axially relative to the threaded locking section 23 so that the locking nut 41 is pressed against the side of the mounting base 1 facing the mating structure 3.

[0068] The diameter of the shoulder portion 22 of the limiting member 2 is larger than the diameter of the first connecting through hole 11. In this way, the shoulder portion 22 and the mounting base 1 can abut against each other to form an axial limiting effect on the limiting member 2. The diameter of the threaded locking section 23 of the limiting member 2 is smaller than the diameter of the first connecting through hole 11. In this way, the threaded locking section 23 can have a certain amount of movement in the radial direction within the first connecting through hole 11. Thus, the pin portion 21 of the limiting member 2 can move relative to the mounting base 1 during the subsequent docking with the pin hole portion 31 to complete the adaptive adjustment.

[0069] Preferably, the threaded locking section 23 includes a threaded section and a smooth shaft section, such as... Figure 2 As shown, the threaded section is located on the side near the pin portion 21, and the smooth shaft section is located on the side near the shoulder portion 22. The diameter of the smooth shaft section is smaller than the diameter of the threaded section. The smooth shaft section passes through the first connecting through hole 11. The diameter of the first connecting through hole 11 is larger than the diameter of the smooth shaft section and smaller than the diameter of the threaded section. In this way, while ensuring that the limiting member 2 has a certain amount of room for movement relative to the mounting base 1, the shoulder portion 22 can form an abutting fit with the side of the mounting base 1 facing away from the mating structure 3. The end face of the threaded section can form an abutting fit with the side of the mounting base 1 facing the mating structure 3. Thus, the limiting member 2 can be axially limited in two directions, which can prevent the limiting member 2 from completely separating from the mounting base 1.

[0070] The drive assembly 5 can convert the motion of its output end into the rotational motion of the locking nut 41 through a corresponding transmission mechanism. When the locking nut 41 rotates on the threaded locking section 23, based on the characteristics of the threaded connection, the locking nut 41 can move axially relative to the threaded locking section 23 and gradually approach the shoulder 22. When the locking nut 41 is pressed against the side of the mounting base 1 facing the mating structure 3, the shoulder 22 is also pressed against the side of the mounting base 1 facing away from the mating structure 3. In this way, the mounting base 1 can be firmly clamped between the shoulder 22 and the locking nut 41, thereby achieving relative fixation between the limiting member 2 and the mounting base 1. It can be understood that the locking nut 41 can be directly pressed against the side of the mounting base 1 facing away from the mating structure 3; the locking nut 41 can also be pressed against other components, and the indirect pressing and fixing between the locking nut 41 and the mounting base 1 can be achieved through the abutment between the component and the side of the mounting base 1 facing away from the mating structure 3.

[0071] This embodiment is based on the threaded connection between the locking nut 41 and the threaded locking section 23, which can conveniently drive the locking nut 41 to abut against the mounting base 1, thereby using the self-locking property of the locking nut 41 to firmly fix the limiting member 2 on the mounting base 1.

[0072] Optionally, refer to Figure 1 and Figure 2The locking nut 41 has a gear structure 411 on its outer side; the drive assembly 5 includes a drive device 51 and a transmission gear assembly 52, the output end of the drive device 51 is connected to the transmission gear assembly 52, and the transmission gear assembly 52 meshes with the gear structure 411.

[0073] This embodiment uses gear meshing for transmission, which converts the rotation of the output end of the drive device 51 into the rotation of the locking nut 41. This offers advantages such as high transmission efficiency, high transmission accuracy, the ability to transmit large torques, compact structure, and reliability and durability. Furthermore, the transmission ratio can be flexibly adjusted by replacing different specifications of the transmission gear assembly 52 to better adapt to different locking requirements.

[0074] The drive device 51 may be a rotary drive device such as a motor; the transmission gear assembly 52 may include one or more transmission gears, which may be specifically set according to the actual structural layout, space size, transmission direction, transmission ratio and other factors or requirements, and are not limited here.

[0075] Optionally, refer to Figure 1 and Figure 2 The transmission gear assembly 52 includes an output gear 521 and an intermediate gear 522; the output gear 521 is connected to the output end of the drive device 51, and the intermediate gear 522 meshes with the output gear 521 and the gear structure 411 respectively.

[0076] This embodiment achieves multi-stage transmission between the drive device 51 and the locking nut 41 by setting the output gear 521 and the intermediate gear 522. This can better adapt to situations where the distance between the drive device 51 and the locking nut 41 is far, and avoids setting the diameter of the locking nut 41 too large, which would result in excessive space occupation.

[0077] Optionally, refer to Figure 1 and Figure 2 The pin shaft portion 21 is provided with a guide shaft section 211 at one end for insertion into the pin hole portion 31. The diameter of the guide shaft section 211 gradually decreases along the moving direction of the pin shaft portion 21 relative to the pin hole portion 31.

[0078] Optionally, refer to Figure 1 and Figure 2 The pin hole 31 is provided with a guide hole section 311 on the side for the pin shaft 21 to be inserted. The diameter of the guide hole section 311 gradually increases along the moving direction of the pin hole 31 relative to the pin shaft 21.

[0079] Specifically, by providing guide shaft section 211 and / or guide hole section 311, when the limiting member 2 contacts the mating structure 3, the guiding effect of guide shaft section 211 and / or guide hole section 311 can guide the pin shaft part 21 in the active state to move to the position opposite to the pin hole part 31, and further guide the pin shaft part 21 to smoothly insert into the pin hole part 31, thereby improving the smoothness and stability of the pin shaft part 21 and the pin hole part 31 when they are mated, and further improving the tolerance of the limiting member 2 and the mating structure 3, so that the pin shaft part 21 and the pin hole part 31 can still be mated even when there is a large positional deviation.

[0080] Optionally, refer to Figures 1 to 3 The limiting locking mechanism also includes a support base 6, which is movably connected to the mounting base 1. The limiting member 2 is connected to the support base 6, and the driving component 5 is disposed on the support base 6.

[0081] Specifically, the support base 6 can be connected to the mounting base 1 using limiting components such as flexible hinges, riveting parts, and guide rail slider assemblies, so that the support base 6 has a certain degree of freedom of movement relative to the mounting base 1 in the corresponding directions, while preventing the support base 6 from completely separating from the mounting base 1. It should be noted that the movable connection between the support base 6 and the mounting base 1 should not hinder the relative movement between the limiting member 2 and the mounting base 1, so as to ensure that when the limiting member 2 moves relative to the mounting base 1 during the engagement with the mating structure 3, the limiting member 2 can simultaneously drive the support base 6 to move relative to the mounting base 1.

[0082] By setting the support base 6, on the one hand, it can provide an installation base for the drive component 5, and on the other hand, it can ensure that the drive component 5 can move synchronously with the movement of the limiting member 2, so as to maintain the stability of the relative position between the drive component 5 and the locking member 4 on the limiting member 2 during the engagement process, and avoid the disengagement of the transmission cooperation between the drive component 5 and the locking member 4 due to the large movement range of the limiting member 2.

[0083] Optionally, refer to Figures 1 to 3 The limiting locking mechanism also includes a support base 6, which is movably connected to the side of the mounting base 1 facing the mating structure 3. The support base 6 has a second connecting through hole 61, and the threaded locking section 23 passes through and fits in the second connecting through hole 61. The driving component 5 is mounted on the support base 6.

[0084] The locking nut 41 is used to press against the side of the support 6 facing away from the mounting base 1 under the drive of the drive assembly 5, so as to fix the support 6 and the mounting base 1 relative to each other.

[0085] In this embodiment, through the shaft hole cooperation between the threaded locking section 23 and the second connecting through hole 61, when the limiting member 2 moves relative to the mounting base 1 during the process of engaging with the mating structure 3, the limiting member 2 can simultaneously drive the support base 6 to move relative to the mounting base 1.

[0086] After the limiting component 2 and the mating structure 3 complete the limiting engagement, the drive component 5 drives the locking nut 41 to rotate relative to the threaded locking section 23, so that the locking nut 41 moves axially on the threaded locking section 23 in the direction close to the shaft shoulder 22; when the locking nut 41 is pressed against the side of the support seat 6 facing away from the mounting seat 1, the shaft shoulder 22 is also pressed against the side of the mounting seat 1 facing away from the support seat 6. In this way, the mounting seat 1 and the support seat 6 can be firmly clamped between the shaft shoulder 22 and the locking nut 41. Thus, the relative fixation between the limiting component 2, the mounting seat 1 and the support seat 6 is achieved through a single locking operation, which can prevent the drive component 5 and other devices set on the support seat 6 from shaking relative to the mounting seat 1 in the future.

[0087] Preferably, when the drive assembly 5 includes a transmission gear assembly 52, such as Figures 1 to 3 As shown, the intermediate gear 522 in the transmission gear assembly 52 is rotatably connected to the support base 6.

[0088] Optionally, refer to Figures 1 to 3 The mounting base 1 has a third connecting through hole 12, and the support base 6 has a fourth connecting through hole 62;

[0089] The limiting locking mechanism also includes a locking pin assembly 7, which has a first flange portion 71, a pin section 72 and a second flange portion 73 arranged in sequence. The pin section 72 is axially movable through the third connecting through hole 12 and the fourth connecting through hole 62. The diameter of the pin section 72 is smaller than the diameter of the third connecting through hole 12 and / or the diameter of the fourth connecting through hole 62. The first flange portion 71 is used to abut against the side of the mounting base 1 facing away from the support base 6, and the second flange portion 73 is used to abut against the side of the support base 6 facing away from the mounting base 1.

[0090] This embodiment provides a movable connection between the support base 6 and the mounting base 1. Specifically, the pin segment 72 located in the middle of the pin assembly has a certain degree of freedom of movement in the radial direction relative to at least one of the third connecting through hole 12 and the fourth connecting through hole 62, thus allowing the support base 6 to have a certain degree of freedom of movement in the radial direction relative to the mounting base 1. In addition, the pin segment 72 can move axially in the third connecting through hole 12 and the fourth connecting through hole 62, and the first flange portion 71 and the second flange portion 73 located at both ends of the pin assembly can form an axial limiting function. In this way, while ensuring that the support base 6 has a certain degree of freedom of movement in the axial direction relative to the mounting base 1, the support base 6 and the mounting base 1 are prevented from completely separating.

[0091] The pin assembly can be formed by combining connecting bolts and connecting nuts, such as... Figure 3As shown, the threaded portion of the connecting bolt has a stepped structure, wherein the section with a larger diameter near the bolt head is the smooth section, and the section with a smaller diameter away from the bolt head is the threaded section. The connecting nut is threaded onto the threaded section and abuts against the end face at the boundary between the threaded section and the smooth section. Thus, the bolt head and the connecting nut of the connecting bolt constitute the first flange portion 71 and the second flange portion 73, respectively, and the smooth section of the connecting bolt constitutes the pin section 72.

[0092] Preferably, multiple third connecting through holes 12 are distributed around the limiting member 2, and multiple fourth connecting through holes 62 are also distributed around the limiting member 2. Correspondingly, multiple locking pin assemblies 7 are also provided and are inserted into each of the third connecting through holes 12 and the fourth connecting through holes 62. In this way, while ensuring that the support base 6 has a certain degree of freedom of movement relative to the mounting base 1, a good limiting effect is formed between the support base 6 and the mounting base 1 in a relatively uniform manner at various points.

[0093] Please see Figures 1 to 5 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;

[0094] The mounting base 1, limiting component 2, locking component 4, and drive assembly 5 of the limiting locking mechanism are mounted on the land vehicle 1000, and the cooperating structure 3 of the limiting locking mechanism is mounted on the aircraft 2000; or, the mounting base 1, limiting component 2, locking component 4, and drive assembly 5 are mounted on the aircraft 2000, and the cooperating structure 3 is mounted on the land vehicle 1000.

[0095] In this embodiment, the flying vehicle includes, but is not limited to, a split-type flying car; such as Figure 5 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.

[0096] For the specific configuration of the limit locking mechanism, please refer to the above embodiment. Taking an example where the mounting base 1, limit component 2, locking component 4, and drive assembly 5 of the limit locking mechanism are mounted on the land vehicle 1000, and the cooperating structure 3 of the limit locking mechanism is mounted 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:

[0097] In the initial state, the aircraft 2000 is separated from the land vehicle 1000. At this time, the limiting member 2 and the mating structure 3 are not engaged, the locking member 4 is not abutting against the mounting base 1, and the limiting member 2 is in a movable state relative to the mounting base 1. When the aircraft 2000 moves into the land vehicle 1000 to begin the engagement operation, the mating structure 3 will move along the direction closer to the limiting member 2 as the aircraft 2000 moves. When the mating structure 3 moves to contact the limiting member 2, since the limiting member 2 is in a movable state, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, the limiting member 2 can still move to the desired position under the action of the mating structure 3. The precise alignment of the limiting component 2 with the mating structure 3 enables the adaptive adjustment of the limiting component 2, allowing the limiting component 2 and the mating structure 3 to autonomously complete their alignment. When the aircraft 2000 moves to the preset position inside the land vehicle 1000, the mating structure 3 also completes the limiting engagement with the limiting component 2. At this time, the locking component 4 can be driven by the drive component 5 to abut against the mounting base 1, thereby fixing the limiting component 2 and the mounting base 1 relative to each other. This keeps the limiting component 2 and the mating structure 3 in their current limiting engagement state. Thus, the limiting engagement between the aircraft 2000 and the land vehicle 1000 is achieved through the limiting engagement of the limiting component 2 and the mating structure 3.

[0098] Since the 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, the limiting member 2 is in an active state relative to the mounting base 1 in the initial state. Thus, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, when the mating structure 3 contacts the limiting member 2, the limiting member 2 can move under the drive of the mating structure 3 to a position that can accurately align with the mating structure 3. That is, the limiting member 2 achieves adaptive adjustment, so that the limiting member 2 and the mating structure 3 can autonomously complete the alignment and limiting engagement. After the limiting member 2 and the mating structure 3 complete the limiting engagement, the driving component 5 can drive the locking member 4 to abut against the mounting base 1 to fix the limiting member 2 and the mounting base 1 relative to each other, thereby keeping the limiting member 2 and the mating structure 3 in the current limiting engagement state. Based on the solution of this embodiment, the limiting member 2 and the mating structure 3 can have a certain tolerance. Thus, even if there is a certain positional deviation between the limiting member 2 and the mating structure 3, the limiting member 2 and the mating structure 3 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.
