[0052] In order to make the purposes, characteristics and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0053] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0054] In combination with Figure 1 and Figure 2 As shown in the drawings, the embodiments of the present disclosure provide a docking connection device, which comprises a first docking piece 1, a second docking piece 2, a first locking device 3 and a second locking device 4; the first docking piece 1 is provided with a movable part 11 for docking; the second docking piece 2 is provided with a matching part 21 for matching docking with the movable part 11; the first locking device 3 is arranged on the first docking piece 1 and connected with the movable part 11, and is used for adjusting and locking the distance between the movable part 11 and the first docking piece 1 in a first direction; the second locking device 4 is arranged in the matching part 21, and is used for locking the movable part 11 in the matching part 21 in a second direction;

[0055] Wherein, the first docking piece 1 and the second docking piece 2 can move relatively in the first direction and the second direction to make the movable part 11 enter the matching part 21 for docking; in the working condition that the movable part 11 enters the matching part 21, the first locking device 3 corresponds to lock and limit the movable part 11 in the first direction; in the working condition that the movable part 11 moves to the corresponding working condition of the second locking device 4 in the matching part 21, the second locking device 4 corresponds to lock and dock the movable part 11 in the second direction.

[0056] The docking connection device provided by the embodiments of the present disclosure can be applied to the modular docking scene of a split aircraft, but is not limited thereto. The first docking part 1 can be provided with a movable part 11 at the top thereof. The movable part 11 can be specifically provided with a rolling pulley. The rolling pulley is connected with the first docking part 1 in a first direction (vertical direction) and is adjustable, for example, the height of the pulley is adjusted by a screw rod or a hydraulic lifting mechanism. The second docking part 2 can be provided with a matching part 21 at the bottom thereof. The matching part 21 can include a docking slide rail. The slide rail extends in a second direction (horizontal direction). The inlet end of the slide rail can be provided with a flared structure for guiding the rolling pulley to slide in. The first locking device 3 can be integrated in the first docking part 1 and connected with the rolling pulley, for example, an electric push rod or a hydraulic cylinder with a self-locking function, for adjusting the vertical height of the pulley and locking. The second locking device 4 can be embedded in the slide rail, for example, an electromagnetic bolt or a spring buckle, for locking the position of the pulley in the horizontal direction after the pulley is horizontally moved into position.

[0057] The specific docking process of the docking connection device can be as follows.

[0058] Vertical direction pre-adjustment: The first docking part 1 adjusts the vertical height of the rolling pulley through the first locking device 3, so that the height of the pulley is approximately aligned with the height of the inlet end of the slide rail, and a certain height error is allowed.

[0059] Sliding into the slide rail: The first docking part 1 and the second docking part 2 are close to each other in the vertical direction. The pulley enters the inlet end of the slide rail under the adjustment of the first locking device 3 and is automatically adjusted in position through the flared structure of the slide rail and slides into the slide rail in the horizontal direction. The first locking device 3 can start the locking function to fix the pulley in the vertical direction, so as to avoid the pulley from being separated from the slide rail due to vibration or load.

[0060] Horizontal direction locking: The first docking part 1 and the second docking part 2 move relative to each other in the horizontal direction. The pulley slides horizontally in the slide rail until the second locking device 4 is triggered. The electromagnetic bolt is popped out and clamped into the groove on the side of the pulley, the horizontal direction locking is completed, and bidirectional stable docking is achieved.

[0061] Compared with the point-surface docking mode of the split aircraft in the related art, the docking connection device provided by the embodiments of the present disclosure has the following beneficial effects.

[0062] 1. Solving height error redundancy: The vertical adjustment of the first locking device 3 and the flared guide of the slide rail can automatically compensate for the height error (such as uneven ground or landing attitude deviation) during the take-off and landing docking of the split aircraft.

[0063] 2. Efficient docking and smoothness: The pulley rolls along the slide rail with small friction, and the horizontal sliding process is smooth, which significantly shortens the docking time. The flared design of the slide rail allows the pulley to have a certain deviation in the vertical direction, which reduces the requirement for the initial docking accuracy.

[0064] 3. Bidirectional stability: The vertical and horizontal independent locking mechanism ensures the structural stability when subjected to combined loads (such as the vertical gravity of the aircraft and the horizontal inertial force) after docking;

[0065] 4. Low maintenance cost: The mechanical structure of the pulley and the slide rail is simple and reliable, suitable for high-frequency disassembly and assembly scenarios.

[0066] In an implementation, the first lock 3 includes an adjusting member 31 and a one-way locking member 32; one end of the adjusting member 31 is connected with the first docking member 1, and the other end is connected with the movable part 11; the one-way locking member 32 is arranged in the adjusting member; in the working condition that the adjusting member 31 is elongated along the first direction to drive the movable part 11 to enter the fitting part 21, or is contracted along the first direction to drive the movable part 11 to enter the fitting part, the one-way locking member 32 can lock and fix the adjusting member 31.

[0067] Specifically, in combination with Figure 2 and Figure 3 Further details, the first lock 3 is specifically arranged to include an adjusting member 31 and a one-way locking member 32, and the adjusting member 31 can be but not limited to an electric push rod or a screw rod lifting mechanism, one end of which is fixed inside the first docking member 1, and the other end is connected with the movable part 11, for driving the movable part to ascend or descend unidirectionally along the vertical direction; the one-way locking member 32 can be but not limited to a ratchet and pawl mechanism or a self-locking worm, and can be integrated inside the adjusting member 31. In this way, when the adjusting member 31 drives the pulley to ascend or descend into the slide rail, the one-way locking member 32 can be automatically locked unidirectionally to prevent the pulley from retracting due to gravity or vibration; when unlocking is needed, manual or electric unlocking can be performed.

[0068] Specifically, when used in the landing docking of a split-type aircraft, the adjusting member 31 drives the pulley to ascend or descend, the pulley continues to press or press down after contacting the entrance end of the slide rail, and the one-way locking member 32 is automatically locked when the pulley reaches the set height, ensuring stable contact between the pulley and the slide rail; when unlocking, the ratchet or worm locking is released by external command, and the adjusting member 31 retracts the pulley to complete the reset.

[0069] The specific arrangement of the above-mentioned first lock 3 can improve the safety of one-way self-locking through the one-way locking member 32, automatically lock the pulley during ascending or descending, and avoid derailment due to vibration or load change after docking. In addition, when the adjusting member 31 is arranged as an electric push rod or a screw rod mechanism, it can realize millimeter-level height fine adjustment at least, which is suitable for different scene height difference requirements.

[0070] In an embodiment, the second lock 4 comprises a trigger 41 and a limiting lock 42; the trigger 41 is arranged on the fitting part 21 and can be abutted by the movable part 11; the limiting lock 42 is arranged on the fitting part 21 and electrically connected with the trigger 41; in the working condition that the trigger 41 is triggered, the limiting lock 42 can be at least partially popped up from the fitting part 21 and abutted with the movable part 11.

[0071] Specifically, in combination with Figure 2 In further detail, the second lock 4 is specifically arranged to comprise the trigger 41 and the limiting lock 42, and the trigger 41 can be but is not limited to a pressure sensor or a mechanical button, and can be arranged at the end of the slide rail; the limiting lock 42 can be but is not limited to a spring buckle or a pin driven by electromagnet, and is signal connected with the trigger 41. In this way, when the pulley slides horizontally to the end of the slide rail, the pulley presses the trigger 41, and the limiting lock 42 pops up after receiving the signal and is inserted into the limiting hole on the side of the pulley, thereby completing the horizontal locking.

[0072] The specific arrangement of the second lock 4 described above, after the pulley is horizontally moved to the position, the trigger 41 is pressed, and the limiting lock 42 can be popped up within 0.1 seconds in response, thereby achieving instantaneous locking. Moreover, after locking, the pin and the limiting hole of the pulley form mechanical interlocking, and even if the power is off, the locking state is still maintained, thereby having the beneficial effects of being able to quickly respond to instantaneous locking, forming mechanical interlocking after locking, and even if the power is off, the locking state is still maintained.

[0073] In an embodiment, the movable part 11 comprises a rolling pulley, and the rolling pulley is adjustably connected with the first abutting part 1 along a first direction; the fitting part 21 comprises an abutting slide rail, and the abutting slide rail is arranged to extend along a second direction; in the working condition that the first abutting part 1 and the second abutting part 2 move relative to each other along the first direction and the second direction, the rolling pulley can move into one end of the abutting slide rail along the first direction and can move relative to each other in the abutting slide rail along the second direction.

[0074] Specifically, in combination with Figure 2 and Figure 3 In further detail, the movable part 11 can be but is not limited to two groups of rolling pulleys arranged side by side, and the two groups of rolling pulleys can be connected with the first abutting part 1 through bearings to realize adjustment of height along the vertical direction; the fitting part 21 can be but is not limited to a I-shaped slide rail matched with the pulley and extending along the horizontal direction, and the entrance end of the slide rail can also be provided with a flared guiding structure.

[0075] Thus, when the movable part 11 is docked with the matching part 21, the rolling pulley can move into one end of the docking rail in the vertical direction and be guided by the flared structure at the one end of the docking rail to automatically center, and the rolling pulley can also move relatively in the horizontal direction in the docking rail until it is locked and fixed by the second locking device 4 in the docking rail.

[0076] The specific setting mode of the movable part 11 and the matching part 21 allows a larger initial position deviation, reduces the requirement for the landing accuracy of the aircraft, has high fault tolerance in the vertical direction, and the double-pulley + I-beam rail design reduces the sliding friction during docking, realizes silent docking, and improves docking smoothness.

[0077] In an implementable manner, one end of the docking rail forms a docking opening part, and the docking opening part is set in a flared structure with gradually increasing caliber in the direction away from the docking rail.

[0078] Specifically, in combination with Figure 2 Further detailed description, the docking opening part of the docking rail can be set in a flared structure with gradually increasing caliber, for example, the entrance width can be gradually expanded from 20 cm to 50 cm, and the entrance height can be gradually expanded from 5 cm to 15 cm. When the pulley moves down or moves down, even if there is a vertical direction ± 3 cm error, a horizontal direction ± 10 cm error, the flared structure can still guide the pulley to slide into the track.

[0079] Of course, the automatic size of the above-mentioned docking opening part can also be flexibly set according to different docking requirements. Setting the above-mentioned docking opening part can compensate for the height and horizontal deviation when the movable part 11 is docked with the matching part 21, solve the dynamic error problem when the split aircraft takes off and lands, and the flared structure with gradually increasing caliber can convert the vertical kinetic energy of the pulley into horizontal sliding potential energy, avoiding hard collision during docking.

[0080] In an implementable manner, the docking rail includes a first track 211 and a second track 212; along the second direction, the first track 211 and the second track 212 respectively have corresponding parallel sub-tracks parallel to each other, and the two parallel sub-tracks together form a limiting space for the rolling pulley to move; the first track 211 and the second track 212 respectively have a first inclined sub-track 211a and a second inclined sub-track 212a at the end of the docking rail that is docked with the rolling pulley; the first inclined sub-track 211a and the second inclined sub-track 212a are inclined away from each other and cooperate to form a docking opening part.

[0081] Specifically, in combination with Figure 2Further detailed description, the docking slide rail is specifically provided to include the first track 211 and the second track 212, and the parallel sub-track sections of the two are jointly formed into the limiting space for the rolling pulley movement along the horizontal direction, and the parallel sub-track sections of the two further have the first inclined sub-track section 211a and the second inclined sub-track section 212a at the entrance end respectively; the first inclined sub-track section 211a can be specifically extended upward at an angle of 30° with a length of 30 cm, and the second inclined sub-track section 212a can be specifically extended downward at an angle of 45° with a length of 20 cm. In this way, the first inclined sub-track section 211a and the second inclined sub-track section 212a can correspondingly form the “bell mouth”-shaped entrance, and when the rolling pulley rises or moves downward to contact the docking slide rail, the first inclined sub-track section 211a limits the upward jump of the rolling pulley, and the second inclined sub-track section 212a guides the downward pressing of the rolling pulley, thereby jointly realizing the stable entry of the rolling pulley into the track.

[0082] The specific setting mode of the docking slide rail can cooperatively suppress the vibration of the rolling pulley through the first track 211 and the second track 212, ensure that the rolling pulley does not be stuck during the sliding process, and further enable the first inclined sub-track section 211a and the second inclined sub-track section 212a at the end of the docking slide rail to absorb the impact energy when the rolling pulley is docked and protect the locking mechanism.

[0083] In an implementable manner, the first inclined sub-track section 211a is located above the second inclined sub-track section 212a; the first inclined sub-track section 211a extends upward at an angle, and the second inclined sub-track section 212a extends downward at an angle, and the length of the first inclined sub-track section 211a is greater than or equal to the length of the second inclined sub-track section 212a.

[0084] Specifically, in combination with Figure 2 Further detailed description, the first inclined sub-track section 211a is arranged above the second inclined sub-track section 212a, and the first inclined sub-track section 211a extends upward at an angle, and the second inclined sub-track section 212a extends downward at an angle, for example, the length of the first inclined sub-track section 211a is 40 cm, and the angle is adjusted to 25° upward; the length of the second inclined sub-track section 212a is 25 cm, and the angle is adjusted to 40° downward. In this way, the time for the rolling pulley to contact the docking slide rail to the complete entry into the track can be further shortened, and the impact resistance performance of the docking slide rail in the vertical direction can be further improved.

[0085] In an implementable manner, the first docking piece 1 includes a plurality of movable parts 11 for docking; the plurality of movable parts 11 are arranged in parallel and at intervals along the second direction, and the plurality of movable parts 11 can be jointly docked in a cooperating part 21 and are respectively connected by the second locking device 4.

[0086] Specifically, in combination with Figure 2Further in detail, the first docking member 1 can be specifically provided with two, three or more movable parts 11 for docking, and the plurality of movable parts 11 can be arranged at intervals of 50 cm in the horizontal direction. The three groups of movable parts 11 are inserted into the same matching part 21, and the second locking member 4 is correspondingly provided with three limiting locking points in the matching part 21, to realize three-point synchronous locking.

[0087] The specific arrangement of the movable part 11 can realize multi-point load sharing, avoid single-point failure risk, and improve the ability of the docking connection device to resist lateral wind load.

[0088] In addition, the embodiment of the present disclosure also provides a split-type aircraft, which comprises an aircraft module, a cabin module, a chassis module and the above-mentioned docking connection device; the aircraft module is connected with the cabin module, and the cabin module is detachably connected with the chassis module through the docking connection device.

[0089] Specifically, in combination with Figure 4 Further in detail, the split-type aircraft can be, but is not limited to, a split-type flying car, a split-type airplane, etc., and the aircraft module and the cabin module can be separated from the chassis module in the flying state and can be connected with the chassis module in the landing state.

[0090] Since the split-type aircraft comprises the above-mentioned docking connection device, the same beneficial effects can be achieved, which will not be repeated here.

[0091] In an implementable manner, in the cabin module and the chassis module, one is provided with the first docking member 1, and the other is provided with the second docking member 2; in the take-off working condition of the split-type aircraft, the first docking member 1 and the second docking member 2 can be unlocked and separated; in the landing working condition of the split-type aircraft, the first docking member 1 and the second docking member 2 can be correspondingly clamped and docked.

[0092] Specifically, in combination with Figure 2 and Figure 3 Further in detail, the above-mentioned docking connection device is correspondingly arranged in the cabin module and the chassis module, and specifically, the above-mentioned second docking member 2 can be arranged on the bottom side of the cabin module, and the above-mentioned first docking member 1 can be arranged on the top side of the chassis module, so that when the split-type aircraft is in the landing working condition, the cabin module and the chassis module can be correspondingly clamped and docked, and the chassis module can be correspondingly loaded in the landing process.

[0093] In addition, the terms "first", "second", etc. are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implying the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0094] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed by the present disclosure, which should be covered by the protection scope of the present disclosure.
