For example, split aircraft, represented by them, have gradually entered the commercial field. The split aircraft in the prior art generally includes three major parts, namely: an aircraft module, a cockpit module, and a chassis module, and a detachable connection technology is adopted. In the flight mode, the chassis module is separated from the cockpit to reduce air resistance; when landing, they are re-docked to improve stability.

[0003] Due to the configuration characteristics of the split aircraft, corresponding connecting parts are required between the aircraft, the cockpit, and the chassis. However, the existing connection devices are not yet mature. The mainstream docking method is a point-plane docking part.

[0052] To make the objectives, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall 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 accompanying drawings.

[0054] Combined with Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a docking connection device, which includes a first docking member 1, a second docking member 2, a first locking device 3, and a second locking device 4; the first docking member 1 is provided with a movable portion 11 for docking; the second docking member 2 is provided with a mating portion 21 for mating with the movable portion 11; the first locking device 3 is disposed on the first docking member 1 and connected to the movable portion 11 for adjusting and locking the distance between the movable portion 11 and the first docking member 1 in a first direction; the second locking device 4 is disposed in the mating portion 21 for locking the movable portion 11 in the mating portion 21 in a second direction.

[0055] Wherein, the first docking member 1 and the second docking member 2 can move relative to each other in the first direction and the second direction so that the movable portion 11 enters the mating portion 21 for docking; in the condition that the movable portion 11 enters the mating portion 21, the first locking device 3 correspondingly locks and limits the movable portion 11 in the first direction; in the condition that the movable portion 11 moves to correspond to the second locking device 4 in the mating portion 21, the second locking device 4 correspondingly locks and docks the movable portion 11 in the second direction.

[0056] The docking connection device provided by the embodiments of the present disclosure can be applied to, but is not limited to, the modular docking scenario of a split aircraft. Among them: The first docking member 1 can be provided with a movable part 11 at its top. The movable part 11 can be specifically set to include rolling pulleys. The rolling pulleys are adjustably connected to the first docking member 1 in the first direction (vertical direction) through the first locking device 3. For example, the height adjustment of the pulleys is realized through a screw or a hydraulic lifting mechanism; The second docking member 2 can be provided with a mating part 21 at its bottom. The mating part 21 can include a docking slide rail. The slide rail extends in the second direction (horizontal direction), and its inlet end can be set as a flared structure for guiding the rolling pulleys to slide in; The first locking device 3 can be integrated inside the first docking member 1 and connected to the rolling pulleys. For example, it is an electric push rod or a hydraulic cylinder with a self-locking function, which is used to adjust the vertical height of the pulleys and lock them; The second locking device 4 can be embedded inside the slide rail. For example, it is an electromagnetic bolt or a spring buckle, which is used to lock the position of the pulleys in the horizontal direction after the pulleys move horizontally in place.

[0057] The specific docking process of this docking connection device can be as follows:

[0058] Pre-adjustment in the vertical direction: The first docking member 1 adjusts the vertical height of the rolling pulleys through the first locking device 3, so that the height of the pulleys is roughly aligned with the inlet end of the slide rail, allowing a certain height error.

[0059] Sliding into the slide rail: The first docking member 1 and the second docking member 2 approach each other in the vertical direction. The pulleys enter the inlet end of the slide rail under the adjustment of the first locking device 3 and adaptively adjust their positions through the flared structure of the slide rail, and slide into the slide rail in the horizontal direction; And the first locking device 3 can start the locking function to fix the pulleys in the vertical direction to prevent the pulleys from detaching from the slide rail due to vibration or load.

[0060] Locking in the horizontal direction: The first docking member 1 and the second docking member 2 move relative to each other in the horizontal direction. The pulleys slide horizontally in the slide rail until the second locking device 4 is triggered, and the electromagnetic bolt pops out and snaps into the groove on the side of the pulleys to complete the horizontal locking and achieve a two-way stable docking.

[0061] Compared with the point-plane docking method adopted by split aircraft in related technologies, the docking connection device provided by the embodiments of the present disclosure has the following beneficial effects:

[0062] 1. Solving the redundancy of height error: Through the vertical adjustment of the first locking device 3 and the flared guide of the slide rail, the height error (such as uneven ground or landing attitude deviation) during the takeoff and landing docking of split aircraft can be adaptively compensated.

[0063] 2. High-efficiency docking and smoothness: The rolling friction of the pulleys along the slide rail is small, and the horizontal sliding process is smooth, significantly shortening the docking time; The flared design of the slide rail allows a certain deviation of the pulleys in the vertical direction, reducing the requirement for the initial docking accuracy.

[0064] 3. Two-way stability: The vertical and horizontal independent locking mechanisms ensure the structural stability when the composite load (such as the vertical gravity and horizontal inertia force of the aircraft) is borne 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 implementable manner, the first locking device 3 includes an adjusting member 31 and a one-way locking member 32; one end of the adjusting member 31 is connected to the first docking member 1, and the other end is connected to the movable part 11; the one-way locking member 32 is arranged in the adjusting member; in the working conditions where the adjusting member 31 extends along the first direction to drive the movable part 11 into the matching part 21, or contracts along the first direction to drive the movable part 11 into the matching 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 For further detailed description, the first locking device 3 is specifically set to include an adjusting member 31 and a one-way locking member 32, and the adjusting member 31 can be but is not limited to an electric push rod or a screw lifting mechanism. One end of it is fixed inside the first docking member 1, and the other end is connected to the movable part 11, used to drive the movable part to move upward or downward unidirectionally in the vertical direction; the one-way locking member 32 can be but is 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 rise or fall into the slide rail, the one-way locking member 32 can automatically lock unidirectionally to prevent the pulley from retracting due to gravity or vibration; when unlocking is required, the locked state can be manually or electrically released.

[0068] Specifically, when the split aircraft lands and docks, the adjusting member 31 drives the pulley to rise or fall. After the pulley contacts the inlet end of the slide rail, it continues to press or depress. The one-way locking member 32 automatically locks when the pulley reaches the set height to ensure the stable contact between the pulley and the slide rail; when unlocking, the ratchet or worm lock is released through an external command, and the adjusting member 31 retracts the pulley to complete the reset.

[0069] The above specific setting method of the first locking device 3 can improve safety through the one-way self-locking of the one-way locking member 32, automatically lock the pulley during the rising or falling process, avoid derailment caused by vibration or load change after docking. In addition, when the adjusting member 31 is set as an electric push rod or a screw mechanism, the minimum height fine adjustment of millimeter level can be realized to adapt to the height difference requirements of different scenarios.

[0070] In one embodiment, the second locker 4 includes a trigger member 41 and a limit locking member 42; the trigger member 41 is arranged on the matching portion 21 and can be triggered by the movable portion 11; the limit locking member 42 is arranged on the matching portion 21 and is electrically connected to the trigger member 41; when the trigger member 41 is triggered, the limit locking member 42 can at least partially pop up from the matching portion 21 and lock and dock with the movable portion 11.

[0071] Specific, combined Figure 2 In further details, the second locker 4 is specifically configured to include a trigger 41 and a limit lock 42, and the trigger 41 can be, but not limited to, a pressure sensor or a mechanical button, and can be arranged at the end of the slide rail; the limit lock 42 can be, but not limited to, an electromagnetically driven latch or a spring buckle, and is signal-connected to the trigger 41. In this way, when the pulley slides horizontally along the slide rail to the end, the pulley squeezes the trigger 41, and the limit lock 42 pops out after receiving the signal and is inserted into the limit hole on the side of the pulley to complete the horizontal locking.

[0072] The specific setting mode of the second locker 4 is that after the pulley is horizontally moved into position, the trigger member 41 is pressed, and the limit lock member 42 can respond and pop out within 0.1 seconds to achieve instantaneous locking. Moreover, after locking, the latch and the pulley limit hole form a mechanical interlock, and the locked state is maintained even if the power is off, which has the beneficial effects of being able to quickly respond to instantaneous locking, forming a mechanical interlock after locking, and maintaining the locked state even if the power is off.

[0073] In one embodiment, the movable part 11 includes a rolling pulley, and the rolling pulley is adjustably connected to the first docking member 1 along a first direction; the matching part 21 includes a docking slide rail, and the docking slide rail is extended along a second direction; under the condition that the first docking member 1 and the second docking member 2 move relative to each other along the first direction and the second direction, the rolling pulley can move along the first direction into one end of the docking slide rail, and can move relatively in the docking slide rail along the second direction.

[0074] Specific, combined Figure 2 and Figure 3 To further explain in detail, the movable part 11 can be but not limited to being configured as two sets of side-by-side rolling pulleys, and the two sets of rolling pulleys can be connected to the first docking member 1 through bearings to achieve height adjustment in the vertical direction; the matching part 21 can be but not limited to being configured as an I-shaped slide rail matching the pulley and extending in the horizontal direction, and the entrance end of the slide rail can also be provided with a flared guide structure.

[0075] When the moving part 11 is docked with the mating part 21 in this way, the rolling pulley can move vertically into one end of the docking slide rail, and the pulley is automatically centered by the flared structure at one end of the docking slide rail. After the rolling pulley enters the docking slide rail, it can also move relatively in the docking slide rail horizontally until it is locked and fixed by the second locking device 4 in the docking slide rail.

[0076] For the specific setting methods of the above-mentioned moving part 11 and mating part 21, the flared structure allows a large initial position deviation, reduces the requirements for the landing accuracy of the aircraft, and has high fault tolerance in the vertical direction; in addition, the double pulley + I-beam rail design reduces the sliding friction during docking, realizes silent docking, and improves the docking smoothness.

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

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

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

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

[0081] Specifically, combined with Figure 2For further detailed description, the docking slide rail is specifically arranged to include a first rail 211 and a second rail 212. Along the horizontal direction, the parallel sub-rail segments of the two together form a limiting space for the rolling pulley to move, and the parallel sub-rail segments of the two also respectively have a first inclined sub-rail segment 211a and a second inclined sub-rail segment 212a at the entrance end; the first inclined sub-rail segment 211a can specifically extend obliquely upward at an angle of 30° for a length of 30 cm, and the second inclined sub-rail segment 212a can specifically extend obliquely downward at an angle of 45° for a length of 20 cm. In this way, the first inclined sub-rail segment 211a and the second inclined sub-rail segment 212a can correspondingly form a "flare" - shaped entrance. When the rolling pulley moves up or down and contacts the docking slide rail, the first inclined rail segment 211a restricts the rolling pulley from jumping up, and the second inclined rail segment 212a guides the rolling pulley to press down, jointly realizing the smooth entry of the rolling pulley into the rail.

[0082] The above - mentioned specific setting method of the docking slide rail can cooperate with the first rail 211 and the second rail 212 to suppress the vibration of the rolling pulley and ensure that there is no jamming during the sliding - in process of the rolling pulley. Moreover, the first inclined sub - rail segment 211a and the second inclined sub - rail segment 212a at the end of the docking slide rail can also be used to absorb the impact energy during the docking of the rolling pulley and protect the locking mechanism.

[0083] In an implementable embodiment, the first inclined sub - rail segment 211a is located above the second inclined sub - rail segment 212a; the first inclined sub - rail segment 211a extends obliquely upward, the second inclined sub - rail segment 211a extends obliquely downward, and the length of the first inclined sub - rail segment 211a is greater than or equal to the length of the second inclined sub - rail segment 212a.

[0084] Specifically, in combination with Figure 2 For further detailed description, the first inclined sub - rail segment 211a is arranged above the second inclined sub - rail segment 212a, and the first inclined sub - rail segment 211a extends obliquely upward and the second inclined sub - rail segment 211a extends obliquely downward. For example, the length of the first inclined sub - rail segment 211a is 40 cm and the inclination angle is adjusted to 25° obliquely upward; the length of the second inclined sub - rail segment 212a is 25 cm and the inclination angle is adjusted to 40° obliquely downward. This can further shorten the time for the rolling pulley to completely enter the rail from contacting the docking slide rail, and can also improve the anti - impact performance of the docking slide rail in the vertical direction.

[0085] In an implementable embodiment, the first docking member 1 includes a plurality of movable parts 11 for docking; the plurality of movable parts 11 are arranged in parallel at intervals along the second direction, and the plurality of movable parts 11 can jointly dock in a mating part 21 and are respectively locked and connected by a second lock 4.

[0086] Specifically, in combination with Figure 2For further detailed description, two, three or more movable parts 11 for docking can be specifically arranged in the first docking part 1, and the multiple movable parts 11 can be arranged at intervals of 50 cm in the horizontal direction. The three groups of movable parts 11 are jointly inserted into the same mating part 21, and the second locking device 4 is correspondingly provided with three limit locking points in the mating part 21 to achieve three-point synchronous locking.

[0087] The specific setting method of the above-mentioned movable part 11 can realize multi-part load sharing, avoid the risk of single-point failure, and moreover, the multiple movable parts 11 can also enhance the ability of the docking connection device to resist lateral wind loads.

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

[0089] Specifically, in combination with Figure 4 For further detailed description, the split-type aircraft can be, but is not limited to, a split-type flying car, a split-type airplane, etc. The aircraft module and the cockpit module can be separated from the chassis module body in the flight state, and can be docked and connected to the chassis module body in the landing state.

[0090] Since the split-type aircraft includes the above-mentioned docking connection device, it can achieve the same beneficial effects, which will not be elaborated here.

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

[0092] Specifically, in combination with Figure 2 and Figure 3 For further detailed description, the above-mentioned docking connection device is correspondingly arranged in the cockpit module and the chassis module. Specifically, the above-mentioned second docking part 2 can be arranged on the bottom side of the cockpit module, and the above-mentioned first docking part 1 can be arranged on the top side of the chassis module. In this way, when the split-type aircraft is in the landing condition, it can be correspondingly locked and docked through the cockpit module and the chassis module, and the chassis module can correspondingly bear the load during the landing process.

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.
