Description

Technical Field

[0001] This utility model relates to a drone transportation locking mechanism, specifically a coaxial drone transportation locking mechanism, belonging to the technical field of drone transportation fixing devices. Background Technology

[0002] Coaxial dual-rotor drones are widely used in the field of small, light and miniaturized unmanned helicopters due to their advantages of small size, no tail rotor and high hovering efficiency. During transportation, coaxial drones generally need to be locked to prevent them from moving.

[0003] However, traditional locking mechanisms often only clamp and fix the body of the coaxial drone, neglecting to fix the rotor. As a result, during transportation, vehicle bumps and shaking during handling can cause the rotor to rotate due to inertia in its free state. This can easily cause the rotor blades to collide with the inner wall of the storage box or other objects, resulting in damage to the blades. This increases the maintenance cost of a single drone by about 20%-30%, and in severe cases, it can even affect the safety and stability of the drone's subsequent flight. Utility Model Content

[0004] The purpose of this invention is to provide a coaxial drone transport locking mechanism to solve the above problems. This mechanism can fix the body of the coaxial drone and its rotor at the same time, preventing damage to the rotor during transportation and thus improving the safety of transportation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a coaxial UAV transport locking mechanism, including a tray, a connecting frame fixedly connected to the tray, a cover abutting the top of the connecting frame, a blocking structure provided on the connecting frame, the blocking structure including a sliding rod and a stop block, two sliding rods slidably connected to the connecting frame, a stop block rotatably connected to the sliding rod, two slots provided on the cover, the stop block engaging with the adjacent slot, a stop plate fixedly connected to one end of the sliding rod, the two stop plates abutting against the same coaxial UAV body, and a spring sleeved on the outside of the stop plate.

[0006] Preferably, the slide bar has a cross-section, and the cross-section of the stop block near the slot is trapezoidal.

[0007] Preferably, one end of the spring abuts against the abutment plate, and the other end of the spring abuts against the connecting frame.

[0008] Preferably, the bottom end of the stop block has an L-shaped cross-section, and the connecting frame has two openings.

[0009] Preferably, two pressure blocks are fixedly connected to both sides of the shield, and the bottom end of the pressure block abuts against the coaxial UAV body.

[0010] Preferably, four positioning sleeves are fixedly connected to the pallet, and the four support legs at the bottom of the coaxial UAV body are respectively engaged with the four positioning sleeves.

[0011] Preferably, the four positioning sleeves are arranged in a circumferential array about the center of the tray, wherein the height of the cross-section of two opposite positioning sleeves is greater than the height of the cross-section of the other two opposite positioning sleeves.

[0012] Preferably, two positioning blocks are fixedly connected to the top of the connecting frame, and the two positioning blocks engage with the same baffle.

[0013] Preferably, the two positioning blocks are symmetrically distributed about the middle of the connecting frame, and the top of the cross-section of the positioning blocks has a trapezoidal structure.

[0014] The beneficial effects of this utility model are: during the installation of the coaxial drone body, one end of the stop block can abut against the connecting frame. At this time, the distance between the two stop plates is relatively large, thus facilitating the placement of the coaxial drone body. After the coaxial drone body is placed, the two rotors can be manually rotated to face a specific direction. Then, the stop cover can be moved to the outside of the two rotors. When the bottom end of the stop cover abuts against the connecting frame, its inner side will just abut against the outer side of the two rotors, thereby achieving the abutment and fixation of the rotors and preventing the rotors from being damaged during transportation. This design effectively improves safety during transportation by preventing damage from large-scale rotation and collisions between the shield and the transport container. When the shield comes into contact with the connecting frame, the stop block can rotate 180 degrees. At this time, the spring will contract and drive the stop plate to move towards the coaxial drone body and come into contact with it. At this time, the other end of the stop block will engage with the slot, making it impossible for the shield and the connecting frame to separate. Therefore, while fixing the shield, it can also fix the coaxial drone body by contact, making the coaxial drone body more secure. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, a coaxial UAV transport locking mechanism includes a tray 1, a connecting frame 2 fixedly connected to the tray 1, a cover 3 abutting the top of the connecting frame 2, a blocking structure 5 provided on the connecting frame 2, the blocking structure 5 including a sliding rod 501 and a stop block 502, two sliding rods 501 slidably connected to the connecting frame 2, a stop block 502 rotatably connected to the sliding rod 501, two slots 506 provided on the cover 3, the stop block 502 engaging with the adjacent slot 506, a stop plate 503 fixedly connected to one end of the sliding rod 501, the two stop plates 503 abutting against the same coaxial UAV body 6, and a spring 504 sleeved on the outside of the stop plate 503.

[0023] As a technical optimization of this utility model, the slide rod 501 is provided with a cross-section 505, which can prevent rotation between the slide rod 501 and the connecting frame 2. The cross-section of the stop block 502 near the slot 506 is trapezoidal, which can play a role in guiding the movement when the stop block 502 and the slot 506 are engaged.

[0024] As a technical optimization of this utility model, one end of the spring 504 abuts against the abutment plate 503, and the other end of the spring 504 abuts against the connecting frame 2. Therefore, under the action of the spring 504, the stop block 502 can always abut against the cover 3, and at the same time, the abutment plate 503 abuts against the coaxial UAV body 6 to further fix the coaxial UAV body 6.

[0025] As a technical optimization of this utility model, the bottom section of the stop block 502 has an L-shaped structure, and the connecting frame 2 is provided with two openings 9. Therefore, when the stop block 502 and the connecting frame 2 are in contact, its end will be located inside the opening 9, thereby limiting the stop block 502.

[0026] As a technical optimization of this utility model, four positioning sleeves 7 are fixedly connected to the tray 1, and the four support legs at the bottom of the coaxial drone body 6 are respectively engaged with the four positioning sleeves 7. Two pressure blocks 4 are fixedly connected to both sides of the cover 3. The bottom end of the pressure block 4 abuts against the coaxial drone body 6. Therefore, the pressure block 4 can abut against the coaxial drone body 6, and the four positioning sleeves 7 are engaged with the four support legs on the coaxial drone body 6 to fix the coaxial drone body 6.

[0027] As a technical optimization of this utility model, the four positioning sleeves 7 are arranged in a circumferential array about the middle of the support plate 1. The height of the cross section of two opposite positioning sleeves 7 is greater than the height of the cross section of the other two opposite positioning sleeves 7. Therefore, during the placement of the coaxial UAV body 6, two of its bottom support legs can first engage with two of the positioning sleeves 7 respectively, and then the position can be adjusted so that the other two bottom support legs engage with the other two positioning sleeves 7 respectively, thereby facilitating the rapid positioning of the coaxial UAV body 6.

[0028] As a technical optimization of this utility model, two positioning blocks 8 are fixedly connected to the top of the connecting frame 2. Therefore, when placing the cover 3, the cover 3 can be positioned by the two positioning blocks 8 engaging with the cover 3 at the same time. The two positioning blocks 8 engage with the same cover 3.

[0029] As a technical optimization of this utility model, the two positioning blocks 8 are symmetrically distributed about the middle of the connecting frame 2, and the top of the cross section of the positioning block 8 is trapezoidal, so it can play a role in guiding the movement when the positioning block 8 and the cover 3 are engaged.

[0030] In use, during the installation of the coaxial drone body 6, one end of the stop 502 abuts against the connecting frame 2. At this time, the distance between the two abutments 503 is relatively large, thus facilitating the placement of the coaxial drone body 6. During the placement of the coaxial drone body 6, two of its bottom support legs first engage with two of its positioning sleeves 7, and then the position is adjusted so that the other two bottom support legs engage with the other two positioning sleeves 7. When all four support legs engage with the four positioning sleeves 7, the coaxial drone body 6 is initially positioned. Then, by manually rotating the two rotors to face a specific direction, the cover 3 can be moved to the outside of the two rotors. When the bottom of the cover 3 abuts against the connecting frame 2, its inner side will just abut against the outside of the two rotors, thereby achieving the abutment and fixation of the rotors. To prevent the rotor from rotating excessively during transportation and from colliding with the transport container, thus effectively improving transportation safety, when the cover 3 abuts against the connecting frame 2, the bottom ends of multiple pressure blocks 4 also abut against the coaxial drone body 6. At this time, the coaxial drone body 6 cannot move, thus fixing the coaxial drone body 6. When the cover 3 abuts against the connecting frame 2, the stop block 502 can be rotated 180 degrees. At this time, the spring 504 will contract and drive the stop plate 503 to move towards the coaxial drone body 6 and abut against the coaxial drone body 6. At this time, the other end of the stop block 502 will engage with the slot 506, so that the cover 3 and the connecting frame 2 cannot be separated. Therefore, while fixing the cover 3, it can also abut against and fix the coaxial drone body 6, thus making the coaxial drone body 6 more firmly fixed.
