Description

Technical Field

[0001] The utility model relates to the technical field of aircraft take-off, in particular to a separation and release mechanism on a take-off and landing platform for fixing and releasing an aircraft. Background Art

[0002] Fixed-wing aircraft have outstanding advantages over rotary-wing aircraft in terms of mission load, cruising capability, aerial relay communication, search and rescue, etc. However, fixed-wing aircraft need to glide a certain take-off distance and reach take-off speed before they can take off. For environments where the take-off distance cannot be provided, such as when a fixed-wing aircraft takes off from a ship, a rotary-wing aircraft that can take off and land vertically can be used as a take-off and landing platform for the fixed-wing aircraft. The use of a take-off and landing platform has the advantages of being fast, reliable, and capable of multiple batches, and the take-off and landing platform takes up little space on the mother ship.

[0003] The rotorcraft carries the fixed-wing aircraft and takes off vertically from the mother ship. After reaching a certain height and speed, the fixed-wing aircraft separates from the rotorcraft to perform the mission. After the fixed-wing aircraft completes the mission, it docks with the rotorcraft in the air and lands vertically on the mother ship with the rotorcraft to complete recovery.

[0004] When a rotorcraft carries a fixed-wing aircraft for takeoff, the two need to be reliably connected to form a whole; when reaching a certain height and speed, the fixed-wing aircraft and the rotorcraft need to be disconnected to form a reliable separation so that the fixed-wing aircraft can complete takeoff.

[0034] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0035] refer to Figure 1 , Figure 2 and Figure 3 The utility model provides a separation release mechanism 100 for fixing and releasing an aircraft, which has an open state and a closed state. The separation release mechanism 100 can be used as a part of a carrying platform, and is used to releasably connect the aircraft to be taken off. Among them, the aircraft to be taken off includes but is not limited to fixed-wing aircraft. The following description takes a fixed-wing aircraft as an example. When the carrying platform carries the fixed-wing aircraft for takeoff, the separation release mechanism 100 is in a closed state, and the carrying platform and the fixed-wing aircraft are connected to form a whole through the separation release mechanism 100; when a certain height and speed are reached, when the fixed-wing aircraft needs to be separated from the carrying platform, the separation release mechanism 100 is adjusted to an open state, so that the fixed-wing aircraft can be detached from the carrying platform to complete the takeoff. In some embodiments, the initial state of the separation release mechanism 100 is an open state.

[0036] The separation release mechanism 100 disclosed in the present invention includes two clamp arms (a first clamp arm 10 and a second clamp arm 20), a knob 30 and an elastic member. Both clamp arms include a forearm and a rear arm. The knob 30 is rotatably disposed between the rear arms of the two clamp arms and can rotate between a first rotation position and a second rotation position. The elastic member is coupled to the rear arms of the two clamp arms and applies an elastic force to bring the rear arms of the two clamp arms closer together, thereby opening the forearms of the two clamp arms. Wherein, under the action of the knob 30 and the elastic member, the two clamp arms rotate in opposite directions along the corresponding rotation axis respectively. When the knob 30 is located at the first rotation position, the rear arms of the two clamp arms are brought closer together under the action of the elastic member, thereby opening the forearms of the two clamp arms, and the separation release mechanism 100 is in an open state; when the knob 30 is located at the second rotation position, the rear arms of the two clamp arms are pushed apart by the knob, thereby closing the forearms of the two clamp arms, and the separation release mechanism 100 is in a closed state.

[0037] See also Figure 4 Specifically, two clamp arms are arranged in parallel to form a clamp, and the two clamp arms are respectively a first clamp arm 10 and a second clamp arm 20. The first clamp arm 10 can rotate around a first rotation axis, and includes a front arm 12 and a rear arm 14, wherein the first rotation axis is located at a connection portion between the front arm 12 and the rear arm 14; the second clamp arm 20 can rotate around a second rotation axis, and includes a front arm 22 and a rear arm 24, wherein the second rotation axis is located at a connection portion between the front arm 22 and the rear arm 24. When the separation release mechanism 100 is in an open state, the two front arms open radially outward, and the two rear arms are brought together; when the separation release mechanism 100 is in a closed state, the two front arms are brought together, and the two rear arms open radially outward.

[0038] Specifically, in some embodiments, the first clamp arm 10 includes a first connection hole 16 disposed between the front arm 12 and the rear arm 14, and the second clamp arm 20 includes a second connection hole 26 disposed between the front arm 22 and the rear arm 24. The separation release mechanism 100 includes a first shaft pin 103 and a second shaft pin 104, the first shaft pin 103 is disposed in the first connection hole 16, and the second shaft pin 104 is disposed in the second connection hole 26. The first clamp arm 10 rotates around the first shaft pin 103, the first rotation axis is located at the first shaft pin 103, and the first rotation axis is the axis of the first shaft pin 103; the second clamp arm 20 rotates around the second shaft pin 104, the second rotation axis is located at the second shaft pin 104, and the second rotation axis is the axis of the second shaft pin 104. Optionally, the separation release mechanism 100 further includes an upper shell 50 and a lower shell 60 , the two clamp arms, the knob 30 and the elastic member are all arranged between the upper shell 50 and the lower shell 60 , and the first shaft pin 103 and the second shaft pin 104 are both fixed to the upper shell 50 or the lower shell 60 .

[0039] Optionally, the separation release mechanism 100 further includes at least two bearings 105, at least one bearing 105 is respectively arranged on the first shaft pin 103 and the second shaft pin 104, and the first clamp arm 10 and the second clamp arm 20 are respectively connected to the first shaft pin 103 and the second shaft pin 104 through the bearings 105. Specifically, the separation release mechanism 100 includes four bearings 105, two bearings 105 are respectively arranged on the first shaft pin 103 and the second shaft pin 104. The bearings 105 are arranged to facilitate the clamp arm to rotate around the shaft pins.

[0040] Alternatively, in some embodiments, the first clamp arm 10 is provided with a first mounting shaft located between the front arm 12 and the rear arm 14, and the second clamp arm 20 is provided with a second mounting shaft located between the front arm 22 and the rear arm 24. The separation release mechanism 100 includes a first matching hole and a second matching hole, the first mounting shaft is provided in the first matching hole, and the second mounting shaft is provided in the second matching hole. For example, the first matching hole and the second matching hole are both provided in the upper shell 50 or the lower shell 60. The first rotation axis is the axis of the first mounting axis, and the second rotation axis is the axis of the second mounting axis. The following description is made by taking the first clamp arm 10 provided with the first connecting hole 16 and the second clamp arm 20 provided with the second connecting hole 26 as an example.

[0041] Specifically, in some embodiments, the elastic member is disposed between the rear arms 14 and 24 of the two clamp arms, and the elastic member is configured as a tension spring, and both ends of the tension spring are connected to the inner sides of the rear arms of the two clamp arms, and the tension spring applies a pulling force to the rear arms of the two clamp arms to bring them closer together. When the knob 30 is located at the second rotation position, the tension spring is stretched; when the knob 30 is rotated from the second rotation position to the first rotation position, the tension of the tension spring brings the rear arms of the two clamp arms closer together.

[0042] In another embodiment, the elastic member is disposed on the outer side of the rear arms of the two clamp arms. Specifically, in some embodiments, the elastic member is configured as a U-shaped spring sheet, and the two ends of the U-shaped spring sheet are respectively connected to the outer sides of the rear arms of the two clamp arms, and the U-shaped spring sheet applies an elastic force to the rear arms of the two clamp arms to move closer to each other. In other embodiments, the elastic member is configured as two, and the two elastic members are respectively disposed on the outer sides of the rear arms of the two clamp arms. Each elastic member includes a fixed portion and a movable portion, and each movable portion is coupled to the outer side of a rear arm, and each fixed portion can be fixed to the upper shell 50 or the lower shell 60. Specifically, each elastic member is a torsion spring or a spring sheet. More specifically, see Figure 3 , Figure 4The separation release mechanism 100 includes a first elastic member 101 and a second elastic member 102. The first elastic member 101 includes a fixed portion 101a and a movable portion 101b, and the second elastic member 102 includes a fixed portion 102a and a movable portion 102b. Both elastic members are V-shaped spring sheets. The first elastic member 101 and the second elastic member 102 are both fixed to one of the upper shell 50 and the lower shell 60. Specifically, the free end of the movable portion of the first elastic member 101 is arranged close to the free end of the rear arm 14, and the free end of the movable portion of the second elastic member 102 is arranged close to the free end of the rear arm 24.

[0043] Continue to see Figure 3 , Figure 4 Preferably, the rear arms 14 and 24 are both configured in a strip shape, the rear arm 14 includes an outer wall 145 and an inner wall 146, and the rear arm 24 includes an outer wall 245 and an inner wall 246. The movable portion of the first elastic member 101 abuts against the outer wall 145, and the movable portion of the second elastic member 102 abuts against the outer wall 246.

[0044] Specifically, the upper shell 50 and the lower shell 60 each include a plate-shaped body, and at least one of them is provided with a spacer extending in the height direction, and the spacer forms a space between the upper shell 50 and the lower shell 60 to accommodate the clamp arm, the knob and the elastic member. The upper shell 50 and the lower shell 60 can be detachably connected by bolts or the like. Figure 3 Optionally, the upper shell 50 is provided with a spacer 54. Specifically, the front side and the rear side of the upper shell are respectively provided with a spacer 54, and the spacer 54 located on the front side is also provided with an opening 56, and the forearms 12 and 22 of the two clamping arms can extend from the opening 56 to the outside of the upper shell and the lower shell. The first elastic member 101 and the second elastic member 102 can be detachably fixed to the spacer 54 by bolts or the like. Preferably, see Figure 4 The lower housing 60 is further provided with a contact platform 66 protruding from the plate-shaped body, and the contact platform 66 is used to support the connection portion of the front arm 12 and the rear arm 14 of the first clamp arm, and the connection portion of the front arm 22 and the rear arm 24 of the second clamp arm. The first shaft pin 103 and the second shaft pin 104 can be fixedly connected to the contact platform 66 by welding or the like. Supporting the first clamp arm 10 and the second clamp arm 20 by the contact platform 66 is conducive to reducing the contact area between the first clamp arm 10, the second clamp arm 20 and the lower housing 60, thereby reducing the friction resistance when the two clamp arms rotate.

[0045] Preferably, see Figure 4, the front arm 12 is provided with an arc portion 122, and the front arm 22 is provided with an arc portion 222. When the separation release mechanism 100 is closed, the arc portion 122 and the arc portion 222 form a ring, which can be used to hold the landing gear of the fixed-wing aircraft to be taken off. More preferably, the arc portion 122 and the arc portion 222 are arranged on the outside of the upper shell 50 and the lower shell 60. Optionally, the lower shell 60 is also provided with a limit block 64, which is arranged between the rear arms of the two clamping arms and close to the front arm. The limit block 64 protrudes from the plate-like body of the lower shell. Optionally, the limit block 64 can also be arranged on the inner surface of the upper shell 50, and the limit protrusion 64 extends downward between the rear arms of the two clamping arms. When the rear arms 14 and 24 contact the limit block 64, the limit block 64 will limit the rear arms 14 and 24 from continuing to move closer under the push of the elastic member. The two clamping arms remain stably open under the joint action of the limit block 64 and the elastic member. In addition, the limit block 64 can also prevent the two clamping arms from interfering with or colliding with the knob 30 and the like.

[0046] Specifically, see Figure 4 The knob 30 includes a main body 32, which is configured in a straight line. When the two ends of the main body 32 contact the inner side wall 146 of the rear arm 14 and the inner side wall 246 of the rear arm 24, the rear arms 14 and 24 are pushed. The knob 30 rotates between the first rotation position and the second rotation position to gradually open or close the rear arms 14 and 24. Optionally, the two ends of the main body 32 are chamfered to facilitate the knob 30 to push the rear arms more smoothly when rotating. In particular, see Figure 5 , Figure 6 , the rotation angle of the knob 30 from the second rotation position to the first rotation position is 90°, and the two clamp arms rotate along the corresponding rotation axis at the same angle, and the angle is 10° to 45°, preferably, the angle is 20° to 30°. Alternatively, in some embodiments, the main body 32 of the knob can be configured as a ratchet. When the outer periphery of the ratchet contacts the inner side wall 146 of the rear arm 14 and the inner side wall 246 of the rear arm 24, the rear arms 14 and 24 are pushed. The following continues to be described by taking the main body 32 configured as a straight line as an example.

[0047] Specifically, see Figure 4The rear arm 14 of the first clamp arm 10 is provided with a limiting protrusion 142, and the rear arm 24 of the second clamp arm 20 is provided with a limiting protrusion 242. The limiting protrusions 142 and 242 are used to limit the rotation of the knob 30. When the knob 30 rotates from the first rotation position to the second rotation position, the limiting protrusions 142 and 242 contact the knob 30 respectively, and the limiting protrusions 142 and 242 limit the knob 30 in the radial direction to prevent the knob 30 from continuing to rotate, and the limiting protrusions 142 and 242 are respectively located on both sides of the knob 30. More specifically, the rear arm 14 of the first clamp arm 10 is also provided with a recess 144, and the recess 144 is adjacent to the limiting protrusion 142; the rear arm 24 of the second clamp arm 20 is also provided with a recess 244, and the recess 244 is adjacent to the limiting protrusion 242. When the knob 30 is located at the second rotation position, two ends of the knob 30 are located at the recess 144 and the recess 244 respectively.

[0048] Specifically, see Figure 2 , Figure 3 The release mechanism 100 further includes a power system 40 for driving the knob 30 to rotate. The power system 40 is provided with an output shaft 42, and the output shaft 42 is coupled to the knob 30. The power system may be a motor, preferably a steering gear. More specifically, the output shaft 42 may be connected to the knob 30 directly or through a gear or the like. Figure 3 Optionally, the output shaft 42 is directly connected to the middle of the knob 30. Figure 4 The middle portion of the main body 32 of the knob 30 is configured as a tube 36 extending in the height direction. The tube 36 is provided with an axial hole 34 , and the output shaft 42 extends into the axial hole 34 .

[0049] Specifically, see Figure 3 , Figure 4 , the lower housing 60 is provided with a mounting hole 62, and at least one of the output shaft 42 and the tube body 36 extends through the mounting hole 62. Optionally, see Figure 3 The upper housing 50 is provided with an observation hole 52, through which the rotation of the knob 30 can be observed. In some embodiments, the tube 36 can extend into the observation hole 52, and the observation hole 52 can limit the knob 30 when the knob 30 rotates.

[0050] See also Figure 5 , the knob 30 is rotated to a vertical position, that is, the knob 30 is in the first rotation position, and the release mechanism 100 is in an open state. At this time, the two ends of the knob 30 do not contact the rear arms 14 and 24, the rear arm 14 is pushed by the first elastic member 101 and limited by the stop block 64 and remains vertical, the rear arm 24 is pushed by the second elastic member 102 and limited by the stop block 64 and remains vertical, and the front arm 12 and the front arm 22 are opened. Figure 6, the knob 30 is rotated counterclockwise to a horizontal position, that is, the knob 30 is located at the second rotation position, and the release mechanism 100 is in a closed state. At this time, the knob 30 pushes the rear arm 14 to keep the forearm 12 vertical, and at the same time pushes the rear arm 24 to keep the forearm 22 vertical, and the forearm 12 and the forearm 22 are closed.

[0051] See also Figure 1 In some embodiments, the separation release mechanism 100 further includes a bracket 70, and the lower shell 60 is disposed on the top of the bracket 70. The bracket 70 includes a top plate 72, a bottom plate 74, a side plate 76 and a back plate 78, and the top plate 72 and the bottom plate 74 are connected by the side plate 76 and the back plate 78. The back plate 78 is disposed on the rear side of the bracket 70, and the bracket 70 includes two side plates 76, and the two side plates 76 are respectively disposed on both sides of the back plate 78, so that an opening is formed on the front side of the bracket 70. The lower shell 60 is disposed on the top plate 72, and the forearms 12 and 22 are located on the front side of the bracket 70, so as to facilitate clamping the landing gear of the fixed-wing aircraft. The power system 40 is disposed in the bracket 70 and fixed to the bracket 70, for example, fixed to the top plate 72.

[0052] See also Figure 7 The fixed-wing aircraft landing gear 201 is provided with a slidable block 202, which is detachably connected to the landing gear 201. Specifically, the slidable block 202 is configured as a detachably connected ring. After the slidable block 202 is sleeved on the landing gear 201 and adjusted to a suitable height position, it can be locked with bolts to prevent it from sliding on the landing gear 201.

[0053] The carrying platform includes a control system, which can control the movement of the power system 40, thereby driving the knob 30 to rotate, and then controlling the opening and closing of the separation release mechanism 100. The initial state of the separation release mechanism 100 is the open state, at which time the knob is in the first rotation position. In the process of the carrying platform assisting the fixed-wing aircraft to take off, the fixed-wing aircraft is first placed on the carrying platform so that the landing gear 201 of the fixed-wing aircraft is placed between the two forearms, and the control system controls the movement of the power system 40 to close the separation release mechanism 100. At this time, see Figure 7 , the separation release mechanism 100 is in the closed state, the knob 30 is in the second rotation position, the forearms 12 and 22 embrace the landing gear 202 to lock it, and the slidable block 204 is blocked by the forearms 12 and 22 to limit the upward movement of the landing gear. After the fixed-wing aircraft is fixed to the carrying platform through the separation release mechanism 100, the carrying platform then carries the fixed-wing aircraft for takeoff and accelerates in the air. When the control system detects that the fixed-wing aircraft has reached the set speed, see Figure 8, the control system controls the power system 40 to move, and then drives the knob 30 to rotate to the first rotation position, and the two clamping arms open the two forearms under the action of the elastic member, and the separation release mechanism 100 is in the open state. The landing gear 202 of the fixed-wing aircraft is released, and the fixed-wing aircraft glides along the sliding direction 204 away from the separation release mechanism 100 and completes the takeoff. Since the fixed-wing aircraft itself has a movement tendency to slide in the sliding direction 204, the fixed-wing aircraft also applies a thrust to the forearms 12 and 22 to open the two, that is, the two clamping arms are opened under the joint action of the elastic member and the fixed-wing aircraft.

[0054] The use of the separation release mechanism 100 disclosed in the present invention can ensure that the fixed-wing aircraft can be stably fixed on the carrying platform before reaching the set speed even under adverse weather conditions. In addition, when the fixed-wing aircraft reaches the set speed, the control system can control the separation release mechanism 100 to open, thereby achieving the separation and release of the fixed-wing aircraft. The separation release mechanism 100 cleverly utilizes the energy of the fixed-wing aircraft and the elastic member, allowing the first clamp arm 10 and the second clamp arm 20 to freely return to their original positions during the separation and release process, that is, to enter the initial open state.

[0055] The separation and release mechanism 100 has a simple structure, a simple control method, low process complexity, reliable functions, easy maintenance, and convenient adjustment. At the same time, the weight and cost of the separation and release mechanism are greatly reduced, and it has great engineering application value.

[0056] The above are only several embodiments of the present disclosure. Those skilled in the art may make various changes or modifications to the embodiments of the present disclosure based on the contents disclosed in the application documents without departing from the spirit and scope of the present disclosure.
