Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drone arm locking devices, and in particular to a drone arm locking device. Background Technology
[0002] A cannon-launched drone is a drone system that uses a launch tube, cannon barrel, or similar platform as a launcher, and leverages gunpowder or other power sources to propel the drone at high speed from the tube. Its principle is to use the launch tube to give the drone a large initial velocity and precise flight direction, enabling it to quickly reach the target area. When the drone is installed inside the launch tube, its arms are folded and stored within the casing, giving the drone a cylindrical structure. Locking components secure the drone arms, preventing friction between the arms and the inner wall of the launch tube during launch. Upon receiving a launch command, the drone is launched at high speed from the launch tube. Simultaneously, the locking components between the arms and the casing release, and elastic elements such as torsion springs release potential energy, driving the arms to quickly pop out from the casing and unfold to the working position.
[0003] Existing locking components typically involve setting slots, latches, and mechanical locking mechanisms on the drone's fuselage to work with the arms. This structure is complex and prone to wear and deformation under frequent use or when subjected to significant external impacts, thus affecting the locking effect. Utility Model Content
[0004] The main purpose of this invention is to propose a drone arm locking device, which aims to improve and simplify the drone dual-arm locking structure.
[0005] To achieve the above objectives, the present invention proposes a drone arm locking device, comprising:
[0006] Two connecting lines, each with a fixing part at one end and a collar at the other end, both fixing parts being used to fix the two arms of the drone;
[0007] A fixed rope, in the form of a loop, is provided with loops on both of the connecting lines; and
[0008] The cutter has a first mounting part and a cutting part. The first mounting part is used to be mounted on the body of a drone, and the cutting part is used to cut the fixing rope when triggered.
[0009] Optionally, the UAV arm locking device further includes two clamps, which are respectively fixed to the two arms, and the two fixing parts are respectively wrapped around the clamps.
[0010] Optionally, the UAV arm locking device further includes a wire clamp, which includes a fixing plate, a limiting plate, and a locking nut. The fixing plate has a wire passage groove, and a stud is provided in the wire passage groove. The two ends of the fixing rope are located in the wire passage groove and are respectively disposed on both sides of the stud. The limiting plate has a through hole, and the limiting plate is sleeved on the stud through the through hole, located in the wire passage groove, and abutting against the fixing rope. The locking nut is screwed to the stud and abuts against the side of the limiting plate opposite to the fixing rope.
[0011] Optionally, the fixing plate has a second mounting part on the side facing away from the cable groove, and the second mounting part is used to fix it to the body of the UAV.
[0012] Optionally, the fixing plate, the limiting plate, and the locking nut are all made of stainless steel.
[0013] Optionally, the fixing rope is made of nylon.
[0014] Optionally, the connecting wire is made of metal.
[0015] This invention utilizes a fixing rope, a cutter, and two connecting lines. Each connecting line has a fixing part at one end and a loop at the other. The two connecting lines are respectively fixed to the two arms of the drone via the fixing rope, and then looped onto the fixing rope via the loops. When the drone's arms are folded to fit snugly against the fuselage, the two connecting lines and the fixing rope are taut, keeping the arms in a relatively fixed position and locking them in place. When the drone completes launch and the arms need to be unfolded, the cutter is triggered, cutting the fixing rope and releasing the connection between the connecting lines and the fixing rope. This eliminates the constraint on the drone's arms, allowing them to move freely. Compared to locking and unlocking drone arms using slots, latches, or mechanical locking mechanisms, this structure, which uses a fixing rope and two connecting lines to lock the two opposing arms and then unlocks them with a cutter, is simpler, faster, and easier to maintain.

[0024] This utility model proposes a locking device for the arm of a drone.
[0025] In the embodiments of this utility model, such as Figure 1As shown, the drone arm locking device includes a fixing rope 20, a cutter 30, and two connecting lines 10; each of the two connecting lines 10 has a fixing part 11 at one end and a collar 12 at the other end, and the two fixing parts 11 are used to fix the two arms of the drone; the fixing rope 20 is looped, and the collars 12 of the two connecting lines 10 are both sleeved on the fixing rope 20; the cutter 30 has a first mounting part and a cutting part, the first mounting part is used to be installed on the drone body, and the cutting part is used to cut the fixing rope 20 when triggered.
[0026] Specifically, when the drone is mounted on the launch tube, the arms need to be folded to fit snugly against the fuselage. Two connecting lines 10 are then fixed to the two opposite arms, each looped around a fixed rope 20. The two connecting lines 10 and the fixed rope 20 are taut, applying a restraining force to the drone's arms and keeping them in a relatively fixed position, thus achieving a locking function. When the drone has finished launching from the launch tube and the arms need to be unlocked, the drone's electronic control device sends a cutting command to the cutter 30. The cutting part of the cutter 30 is triggered, severing the fixed rope 20. The connection between the connecting lines 10 and the fixed rope 20 is released, the restraining force on the drone's arms disappears, and the arms can move freely.
[0027] It's worth noting that typical cannon-launched drones generally have four arms, which can be secured individually using two drone arm locking devices. Furthermore, for drones of different sizes and drone arms, the optimal locking effect can be achieved by adjusting the length and thickness of the connecting cable 10 and the fixing rope 20, as well as the installation position of the cutter 30. Additionally, the materials of the connecting cable 10 and the fixing rope 20 can be adjusted according to the specific operating environment and requirements of the drone, further improving the adaptability of the device.
[0028] This invention utilizes a fixing rope 20, a cutter 30, and two connecting lines 10. Each connecting line 10 has a fixing part 11 at one end and a collar 12 at the other. The two connecting lines 10 are respectively fixed to the two arms of the drone via the fixing rope 20, and then looped onto the fixing rope 20 via the collar 12. When the drone's arms are folded to fit snugly against the fuselage, the two connecting lines 10 and the fixing rope 20 are taut, keeping the arms in a relatively fixed position and locking them in place. When the drone completes launch and the arms need to be unfolded, the cutter 30 is triggered, cutting the fixing rope 20 and releasing the connection between the connecting lines 10 and the fixing rope 20. This eliminates the constraint on the drone's arms, allowing them to move freely. Compared to locking and unlocking the drone arms using slots, latches, or mechanical locking mechanisms, this structure, which uses the fixing rope 20 and two connecting lines 10 to lock the two opposing arms and then unlocks them with the cutter 30, is simpler, faster, and easier to maintain.
[0029] In some embodiments, the drone arm locking device further includes two clamps 50, which are respectively fixed to the two arms, and two fixing parts 11 are respectively wrapped around the clamps 50. Specifically, the two clamps 50 are respectively fixed to the two arms, which can ensure a more secure and reliable connection between the connecting cable 10 and the drone arm, preventing the connecting cable 10 from falling off during use. In addition, clamps 50 of appropriate size can be set for arms of different sizes to better fix the clamps 50 to the drone arms. In other embodiments, a structure for fixing the connecting cable can be directly formed on the drone arm.
[0030] In some embodiments, the UAV arm locking device further includes a wire clamp 40, which includes a fixing plate, a limiting plate, and a locking nut. The fixing plate has a wire passage groove, and a stud is provided in the wire passage groove. The two ends of the fixing rope 20 are located in the wire passage groove and are respectively located on both sides of the stud. The limiting plate has a through hole, and the limiting plate is sleeved on the stud through the through hole and located in the wire passage groove, and abuts against the fixing rope 20. The locking nut is screwed to the stud and abuts against the side of the limiting plate opposite to the fixing rope 20.
[0031] Specifically, during assembly, the two ends of the fixing rope 20 are first placed in the wire guide groove, with each end positioned on either side of the stud. Then, the limiting plate is installed in the wire guide groove through the through hole, pressing down on the fixing rope 20. Next, the locking nut is screwed onto the stud. By rotating the locking nut, its position on the stud can be adjusted, thereby changing the pressure on the limiting plate, causing it to press against the fixing rope 20 and fix it into a loop. After recovering the drone, before reinstalling it into the launch tube, the cut fixing rope 20 can be removed by unscrewing the locking nut from the screw, and a new fixing rope 20 can be installed. Alternatively, in other embodiments, the fixing rope 20 can also be looped by tying knots at both ends.
[0032] In some embodiments, a second mounting portion is provided on the side of the fixing plate facing away from the cable tray, and the second mounting portion is used to fix it to the drone body. Specifically, this allows the cable clamp 40 to be stably installed on the drone body via the second mounting portion, preventing the cable clamp 40 from falling off after the cutter 30 cuts the fixing rope 20, thus enabling the cable clamp 40 to be reused. Alternatively, adhesive can be provided on the second mounting portion to fix the fixing plate to the drone body, or the cable clamp can be directly tied to the drone body using cable ties.
[0033] In some embodiments, the fixing plate, the limiting plate, and the locking nut are all made of stainless steel. Specifically, the fixing plate, the limiting plate, and the locking nut of the wire clamp 40 are made of stainless steel, which has high strength and corrosion resistance, ensuring that they will not loosen or be damaged during long-term use.
[0034] In some embodiments, the fixing rope 20 is made of nylon. Specifically, when the fixing rope 20 is made of nylon, it has high strength and abrasion resistance, and can withstand various forces during the launch of the drone. Moreover, the nylon material also makes it easy for the cutter 30 to cut the fixing rope 20.
[0035] In some embodiments, the connecting wire 10 is made of metal. Specifically, the metal connecting wire 10 has high strength and stability, and can withstand the tension of the drone's arms during launch and flight.
[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
