Detailed implementation manners

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] As Figures 1 to 6 shown, an embodiment of the present invention provides a separation device for a columnar UAV release adapter 21, including a shell 17, having a first cavity 15, a first flanging 2 and a support column 22, a long hole 20 is provided on the support column 22, a through hole 11 is provided at the bottom of the shell 17, and the long hole 20 communicates with the through hole 11. A sleeve 23, located in the first cavity 15, sleeved on the support column 22, having a second flanging 14, an inner boss 12 and a second cavity 18, and the second cavity 18 is located between the inner wall 5 of the sleeve 23 and the outer wall 16 of the sleeve 23. An elastic member, located in the second cavity 18, the elastic member is a spring 3, sleeved on the inner wall 5 of the sleeve 23. A locking pin 24, having a stepped columnar structure, inserted into the long hole 20 and the through hole 11, and locking and releasing the sleeve 23 by rotation. A flange 1 is provided on the shell 17 to realize the cooperation with the adapter 21.

[0039] The housing 17 is the support of the separation device and is embedded on the adapter 21. The sleeve 23 and the spring 3 are assembled inside the housing 17. There are "petal"-shaped flanges on the inner side above the housing 17 and the outer side below the sleeve 23. There is a support column 22 inside the housing 17. The middle part of the support column 22 is oblong, and there is a through hole 11 on the inner side below. There is a cylindrical hole formed by the inner wall in the middle of the sleeve 23, and two inner bosses 12 are arranged on the inner side of the cylindrical hole. The main body of the locking pin 24 is a stepped cylinder, with an external hexagonal flange at the bottom and an oblong shape at the top.

[0040] During assembly, the spring 3 is placed inside the sleeve 23 and sleeved between the inner wall 5 and the outer wall 16 of the sleeve 23. Align the "petal"-shaped concave edge on the inner side above the housing 17 with the "petal"-shaped convex edge on the outer side below the sleeve 23 and press the upper part of the sleeve 23. When the "petal"-shaped convex edge of the sleeve 23 is lower than the "petal"-shaped concave edge of the housing 17, rotate the sleeve 23 so that the "petal"-shaped convex edge of the sleeve 23 is opposite to the "petal"-shaped convex edge of the housing 17, and press the sleeve 23. The spring 3 is compressed until the bottom surface of the sleeve 23 contacts the bottom surface 10 of the housing. The oblong shape (the first pin part 6) at the top of the locking pin 24 is opposite to the oblong shape (the second cylinder 19) in the middle of the housing 17 and extends into the bottom of the housing 17. The convex edge (arc edge) of the oblong shape (the first pin part 6) at the top of the locking pin 24 crosses the inner boss 12 in the middle of the sleeve 23 and rotates 90°. Release the external pressure on the sleeve 23. Under the elastic force of the spring 3, the lower bottom surface of the convex edge (arc edge) of the oblong shape (the first pin part 6) at the top of the locking pin 24 contacts the upper plane of the inner boss 12 in the middle of the sleeve 23, locking the sleeve 23.

[0041] When the separation device for releasing the adapter 21 of the columnar unmanned aerial vehicle works, before the separation device enters the ejection tube with the adapter 21, remove the locking pin 24 by rotating it. When the separation device is in the ejection tube with the adapter 21, under the constraints of the columnar unmanned aerial vehicle and the inner wall of the ejection tube, the spring 3 is in a compressed state. The sleeve 23 and the spring 3 are inside the housing 17. The first cylinder 4 of the support column 22 above the middle of the housing 17 extends into the pin hole of the columnar unmanned aerial vehicle. When the adapter 21 exits the tube with the columnar unmanned aerial vehicle, after the separation device gets rid of the constraints, under the elastic force of the spring 3, the sleeve 23 extends out of the housing 17 and bounces the adapter 21 off the surface of the columnar unmanned aerial vehicle.

[0042] In this embodiment, the housing 17 is embedded in the adapter 21. The housing 17 has a first cavity 15, a first flanging 2, and support columns 22. Long holes 20 are provided on the support columns 22, and through holes 11 are provided at the bottom of the housing 17. The long holes 20 communicate with the through holes 11. The first flanging 2 is arranged at intervals at the upper end of the housing 17 and is distributed in a petal shape. The support columns 22 include a first column body 4 and a second column body 19. A protrusion 13 is provided at the upper end of the through hole 11, and the protrusion 13 is connected to the second column body 19. The long holes 20 are located on the second column body 19, and both side surfaces of the second column body 19 are flat. The function of the housing 17 is, on the one hand, to connect with the adapter 21, and on the other hand, to support and guide the sleeve 23, the spring 3, and the lock pin 24. The first cavity 15 is the inner cavity of the housing 17, and the first cavity 15 is used to accommodate the sleeve 23. The sleeve 23 slides relatively within the first cavity 15. The purpose of setting the first flanging 2 is to cooperate with the second flanging 14 of the sleeve 23 to facilitate the insertion and cooperation of the housing 17 and the sleeve 23, and then lock them after rotation.

[0043] The support columns 22 are provided, on the one hand, to support the guide sleeve 23, and on the other hand, to connect the separation device to the drone through the first column body 4. Long holes 20 are provided at the lower ends of the support columns 22 to accommodate the lock pins 24. The lower end of the sleeve 23 is clamped by the first pin portion 6 of the lock pin 24, so that the spring 3 is in a compressed state, the lower end of the sleeve 23 contacts the inner bottom surface of the housing 17, and the first column body 4 is inserted into the drone. The first flanging 2 and the second flanging 14 are distributed in a petal shape, which is convenient for forming a convex edge and a concave edge, and thus facilitates the rapid assembly and disassembly of the sleeve 23 and the housing 17.

[0044] In this embodiment, the sleeve 23 is located within the first cavity 15 and is sleeved on the support columns 22. It has a second flanging 14, an inner boss 12, and a second cavity 18. The second cavity 18 is located between the inner wall 5 and the outer wall 16 of the sleeve 23. The inner boss 12 is located on the inner wall 5 of the sleeve 23. The second flanging 14 is arranged corresponding to the first flanging 2 and is distributed in a petal pattern. The sleeve 23 slides relatively within the first cavity 15. The outer side of the second flanging 14 has a clearance fit with the inner wall of the housing 17, the outer side of the inner wall 5 of the sleeve 23 has a clearance fit with the protrusion 13, and the end of the inner boss 12 has a clearance fit with the second pin portion 7 of the first column body 4 and the second column body 19.

[0045] The function of the sleeve 23 is to separate the drone and the adapter 21. Among them, the function of the second cavity 18 is to accommodate the spring 3. The upper end of the spring 3 contacts the top of the second cavity 18, and the lower end of the spring 3 contacts the bottom of the housing 17. The purpose of setting the inner boss 12 is to lock and release the lock pin 24. The purpose of setting the second flanging 14 is to cooperate with the first flanging 2, and thus facilitate the rapid assembly and disassembly of the sleeve 23 and the housing 17.

[0046] In this embodiment, the elastic member is located in the second cavity 18 and sleeved on the inner wall 5 of the sleeve 23. The elastic member can adopt elastic elements such as a spring 3 to realize the reset of the sleeve 23 and realize the separation of the adapter 21 and the drone by the reset of the sleeve 23. The sleeve 23 and the first column 4 form a relative telescopic structure. By the relative movement of the sleeve 23 along the first column 4, the separation of the drone and the adapter 21 is realized.

[0047] In this embodiment, the locking pin 24 has a stepped columnar structure and is inserted into the long hole 20 and the through hole 11 to lock and release the sleeve 23 by rotation. The locking pin 24 includes a first pin portion 6, and the first pin portion 6 is connected to the second pin portion 7. The first pin portion 6 and the second pin portion 7 are located in the long hole 20. Two sides of the first pin portion 6 are flat surfaces, and the second pin portion 7 is cylindrical. The distance between the two flat surfaces of the first pin portion 6 is greater than the diameter of the second pin portion 7. The locking pin 24 further includes a third pin portion 8 and a fourth pin portion 9. The third pin portion 8 is located in the through hole 11, and the fourth pin portion 9 is located at the bottom of the housing 17. The third pin portion 8 cooperates with the through hole 11, and the diameter of the fourth pin portion 9 is greater than that of the through hole 11. A card slot is formed between the third pin portion 8 and the first pin portion 6. The other two sides of the first pin portion 6 are arc surfaces, and the arc surfaces are used to clamp the inner boss 12.

[0048] The purpose of setting the locking pin 24 is to lock the sleeve 23 to ensure that when the adapter 21 enters the ejection tube, the first column 4 can be inserted into the drone, and it can be ensured that the adapter 21 and the drone are in a connected and non-separated state. The first pin portion 6 is used to clamp and limit the inner boss 12, so as to ensure that the sleeve 23 is in a compressed state. The second pin portion 7 realizes the connection between the first pin portion 6 and the third pin portion 8. The third pin portion 8 realizes the cooperation with the through hole 11. The fourth pin portion 9 is used to limit the pin portion and will not completely enter the through hole 11.

[0049] In another embodiment of the present invention, a method for using a separation device for releasing the adapter 21 of a columnar drone is provided, including the following steps:

[0050] Step (1): Assemble the spring 3 and the sleeve 23, and place the spring 3 between the inner wall 5 of the sleeve 23 and the outer wall 16 of the sleeve 23.

[0051] Step (2): Assemble the sleeve 23 and the housing 17. Press and sleeve the convex edge of the second flange 14 of the sleeve 23 and the concave edge of the first flange 2 of the housing 17 relatively, and then rotate the sleeve 23 so that the convex edge of the second flange 14 of the sleeve 23 and the convex edge of the first flange 2 of the housing 17 are opposite.

[0052] Step (3): Insert the locking pin 24, press the sleeve 23, and insert the locking pin 24 into the through hole 11 and the long hole 20 at the lower end of the housing 17, and rotate the locking pin 24 to clamp the inner boss 12, thereby locking the sleeve 23.

[0053] Step (4): Connect the separation device to the drone and remove the pin. Insert the first cylinder 4 of the separation device into the drone. When installing the drone and the adapter 21 into the ejection tube, remove the locking pin 24.

[0054] Step (5): The columnar drone releases the adapter 21 for separation. After the adapter 21 exits the tube with the columnar drone, under the elastic force of the spring 3, the adapter 21 is ejected from the surface of the columnar drone.

[0055] Specific steps:

[0056] Step (1): Assemble the spring 3 and the sleeve 23. Place the spring 3 in the second cavity 18 formed by the inner wall 5 and the outer wall 16 of the sleeve 23 of the sleeve 23.

[0057] Step (2): Assemble the sleeve 23 and the housing 17. Align the concave edge of the petal-shaped first flanging 2 on the inner side above the housing 17 with the convex edge of the petal-shaped second flanging 14 on the outer side below the sleeve 23, and press the upper part of the sleeve 23. When the convex edge of the petal-shaped second flanging 14 of the sleeve 23 is lower than the concave edge of the petal-shaped first flanging 2 of the housing 17, rotate the sleeve 23 so that the convex edge of the petal-shaped second flanging 14 of the sleeve 23 is aligned with the convex edge of the petal-shaped first flanging 2 of the housing 17.

[0058] Step (3): Insert the locking pin 24. Press the sleeve 23 to compress the spring 3 until the bottom of the sleeve 23 contacts the inner bottom surface of the housing 17. Insert the locking pin 24 into the through hole 11 and the long hole 20 in sequence, so that the long oval (the first pin part 6) at the top of the locking pin 24 faces the plane and the arc surface of the long oval (the second cylinder 19) in the middle of the housing 17, and extends into the long hole 20 at the lower end of the second cylinder 19 of the housing 17. The convex edge (arc edge) of the long oval (the first pin part 6) at the top of the locking pin 24 crosses the middle inner boss 12 of the sleeve 23 and rotates 90°. Then release the external pressure on the sleeve 23. Under the elastic force of the spring 3, the lower bottom surface of the convex edge (arc edge) of the long oval (the first pin part 6) at the top of the locking pin 24 contacts the upper plane of the middle inner boss 12 of the sleeve 23, locking the sleeve 23.

[0059] Step (4): Connect the separation device to the drone and remove the pin. When the separation device for releasing the adapter 21 by the columnar drone is working, before the separation device enters the ejection tube with the adapter 21, remove the locking pin 24 by rotating it. When the separation device is in the ejection tube with the adapter 21, under the constraint of the columnar drone and the inner wall of the ejection tube, the spring 3 is in a compressed state. The sleeve 23 and the spring 3 are inside the housing 17, and the first cylinder 4 of the support column 22 above the middle of the housing 17 extends into the pin hole of the columnar drone.

[0060] Step (5): The columnar drone releases the adapter 21 for separation. After the adapter 21 exits the tube with the columnar drone, the separation device gets rid of the constraint. Under the elastic force of the spring 3, the sleeve 23 extends out of the housing 17, separates the first column 4 from the adapter 21, and then bounces the adapter 21 off the surface of the columnar drone.

[0061] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: The combined design of the housing 17, the sleeve 23, and the spring 3 adopted by the present invention. By rotating the locking pin 24 and removing the locking pin 24, when the separation device is in the tube with the adapter 21, the sleeve 23 is under the constraints of the columnar drone and the inner wall of the tube, the spring 3 is in a compressed state, the sleeve 23 and the spring 3 are inside the housing 17, and the first column 4 of the support column 22 above the middle of the housing 17 extends into the pin hole of the columnar drone. After the adapter 21 exits the tube with the columnar drone and the separation device gets rid of the constraint, under the elastic force of the spring 3, the sleeve 23 extends out of the housing 17 and bounces the adapter 21 off the surface of the columnar drone. It has the characteristics of compact structure, small space requirement, low cost, and easy implementation. The combined use of the sleeve 23 and the locking pin 24 reduces the assembly time of the separation device and the requirements for assembly tools. It can quickly separate the adapter 21 from the columnar drone, reduce the time the adapter 21 stays in the air, meet the requirements of multi-pack continuous takeoff, with a simple structure and reliable separation.

[0062] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
