Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) supporting equipment technology, and in particular to a modular UAV compartment that automatically flips and separates. Background Technology

[0002] Common payloads for drones include gimbal cameras, electro-optical pods, and motion execution components, all housed in the lowest section of the drone. In some single-trigger mission scenarios, two or more payloads need to work together, with one payload triggering another to perform the mission under specific conditions. Because different payloads are installed in the same or adjacent sections, upon triggering, only one payload must suddenly move away from the others, creating a certain degree of spatial separation. This prevents structural interference with subsequent payload actions and ensures successful mission completion.

[0003] Common modular designs feature fixed connections, using non-metallic materials and 3D printing for one-piece molding. Each compartment has six threaded holes in its cross-section, connected via fasteners. The load-bearing compartments cannot be separated. Existing publication number CN219406931U discloses a modular quick-release structure for drones and the drone itself. The compartments feature a modular quick-release design with multi-point unlocking, allowing for complete manual separation, but automatic unlocking is not possible. It can only be manually disassembled, not automatically separated. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a modular unmanned aerial vehicle (UAV) compartment that can be automatically flipped and separated. It can achieve automatic flipping after being unlocked and triggered, supports the execution of actions in a variety of mission scenarios, and expands the application field of UAVs.

[0005] The technical solution of this utility model is as follows: a modular unmanned aerial vehicle (UAV) compartment with automatic flip-and-separate mechanism, including a compartment frame and a flip-and-separate bracket disposed at the bottom of the compartment frame. One side of the flip-and-separate bracket is hinged to the bottom of the compartment frame, and the other side is connected to the compartment frame via a trigger unlocking component. The trigger unlocking component includes a transmission unlocking structure, a lock body, and a lock tongue. The transmission unlocking structure and the lock body are disposed on the compartment frame, and the lock tongue is disposed on the flip-and-separate bracket and is configured to cooperate with the lock body. The transmission unlocking structure is signal-connected to a trigger, and the output end of the transmission unlocking structure is connected to a lock cylinder rod. The lock cylinder rod passes through the lock body and is inserted into the lock tongue to lock the compartment frame and the flip-and-separate bracket. After the transmission unlocking structure is triggered and drives the lock cylinder rod to be pulled out from the lock tongue, the flip-and-separate bracket moves away from the compartment frame and automatically flips.

[0006] As can be seen from the above scheme, the flip-up bracket is used to load the load, the trigger is used to drive the transmission unlocking structure to move, the output end of the transmission unlocking structure is connected to the lock cylinder rod, and is used to drive the lock cylinder rod to make horizontal feed movement in the lock body to realize locking and unlocking. After the lock body and the lock tongue are set to cooperate with each other, the lock cylinder rod is inserted to realize the connection and locking between the cabin frame and the flip-up bracket. This utility model, by triggering the transmission unlocking structure, drives the lock cylinder rod to be pulled out from the lock tongue, and the flip-up bracket flips away from the cabin frame to the maximum angle, thereby realizing automatic flipping, supporting the execution of actions in various task scenarios, and expanding the application field of UAVs.

[0007] The transmission unlocking structure includes a mounting bracket, a servo motor mounted on the mounting bracket, a first connecting rod, and a second connecting rod. A support plate is provided on the frame, and the mounting bracket is mounted on the support plate. One end of the first connecting rod is connected to the output end of the servo motor, and the other end is rotatably connected to the second connecting rod. One end of the lock cylinder rod is rotatably connected to the second connecting rod, and the other end passes through the lock body and is inserted into the lock tongue. The support plate is provided with a through hole adapted to the lock tongue. Therefore, the support plate is used to mount the servo motor. The servo motor, the first connecting rod, and the second connecting rod form a crank-connecting rod structure. The first connecting rod is equivalent to a crank, and the servo motor drives the first connecting rod to rotate around the servo motor. The second connecting rod connects the first connecting rod and the lock cylinder rod, driving the lock cylinder rod to move back and forth within the lock body.

[0008] The upper surface of the flip bracket is provided with several load mounting holes, and the flip bracket is symmetrically provided with connecting lugs, which are located on the opposite side of the locking tongue. Therefore, the load mounting holes are used to mount loads.

[0009] A connecting seat is provided on the cabin frame. After the connecting seat and the connecting lug mate, they are rotatably connected by a torque connection assembly. Therefore, the connecting seat and the connecting lug, after mate, are used to achieve the hinge connection between the cabin frame and the tilting bracket via the torque connection assembly.

[0010] The torque connection assembly includes a torsion spring, a cylindrical sleeve, and a bolt. The bolt is inserted into the connecting seat after aligning with the connecting lug. The cylindrical sleeve is fitted onto the bolt, with both ends embedded in the connecting lug. The torsion spring is fitted onto the cylindrical sleeve, with its torsion arm abutting against the arcuate groove of the connecting seat. Thus, the cylindrical sleeve drives the flipping bracket to rotate around the bolt, the arcuate groove limits the torsion arm of the torsion spring, and the torsion spring generates elastic potential energy through deformation. After the transmission unlocking assembly unlocks, the elastic potential energy of the torsion spring is converted into the kinetic energy for the flipping bracket to flip, thereby accelerating the automatic opening rate of the flipping bracket.

[0011] The torsion spring is a double torsion spring, and two sets of the arcuate grooves are arranged side by side on the connecting seat.

[0012] The inner wall of the cabin frame is provided with several wall panel fixing holes.

[0013] The flip bracket is provided with sliding grooves on both sides of the connecting lug, and the inner wall of the sliding groove is adapted to the outer wall of the bolt.

[0014] The trigger is a smart terminal. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1 to 7As shown, this utility model is a modular unmanned aerial vehicle (UAV) compartment with automatic flip-and-separate mechanism, including a compartment frame 1 and a flip-and-separate bracket 2 disposed at the bottom of the compartment frame 1. One side of the flip-and-separate bracket 2 is hinged to the bottom of the compartment frame 1, and the other side is connected to the compartment frame 1 via a trigger unlocking assembly. The trigger unlocking assembly includes a transmission unlocking structure 3, a lock body 4, and a locking tongue 5. The transmission unlocking structure 3 and the lock body 4 are disposed on the compartment frame 1, and the locking tongue 5 is disposed on the flip-and-separate bracket 2 and is configured to cooperate with the lock body 4. The transmission unlocking structure 3 is signal-connected to a trigger 10, and the output end of the transmission unlocking structure 3 is connected to a lock cylinder 6. The lock cylinder 6 passes through the lock body 4 and is inserted into the locking tongue 5 to lock the compartment frame 1 and the flip-and-separate bracket 2. After the transmission unlocking structure 3 is triggered and drives the lock cylinder 6 to be pulled out from the locking tongue 5, the flip-and-separate bracket 2 moves away from the compartment frame 1 and automatically flips.

[0018] like Figure 7 As shown, the cabin frame 1 is a polygonal axisymmetric cabin frame. During installation, a wall panel frame 100 is connected to the cabin frame 1. The wall panel frame 100 is composed of several wall panels connected around it. Each side of the cabin frame 1 can be fixed with a wall panel of a corresponding width according to its side length. The cabin body is composed of a set of cabin frames and a set of wall panels. Two adjacent cabin bodies are fixedly connected or separated through the cabin frame 1.

[0019] The transmission unlocking structure 3 includes a mounting bracket 31, a servo motor 32 mounted on the mounting bracket 31, a first connecting rod 33, and a second connecting rod 34. A support plate 11 is provided on the frame 1, and the mounting bracket 31 is mounted on the support plate 11. One end of the first connecting rod 33 is connected to the output end of the servo motor 32, and the other end is rotatably connected to the second connecting rod 34. One end of the lock cylinder rod 6 is rotatably connected to the second connecting rod 34, and the other end passes through the lock body 4 and is inserted into the lock tongue 5. The support plate 11 has a through hole 111 adapted to the lock tongue 5. In this embodiment, the lock cylinder rod 6 is a cylindrical connecting rod with a slot on one end. The end of the second connecting rod 34 extends into the slot and is fitted with a rotating pin to achieve a rotational engagement. The lock body 4 and the mounting bracket 31 are integrally formed.

[0020] In this embodiment, when the rotation fulcrum of the first connecting rod 33 and the second connecting rod 34 moves away from the latch 5, the lock cylinder rod 6 is pulled out from the latch 5 to unlock; when the rotation fulcrum of the first connecting rod 33 and the second connecting rod 34 moves closer to the latch 5, the lock cylinder rod 6 is inserted from the lock body 4 into the latch 5 to lock the cabin frame 1 and the flip bracket 2.

[0021] The frame 1 is provided with a connecting seat 12. The connecting seat 12 and the connecting lug 22 are rotatably connected by a torque connection assembly. The inner side wall of the frame 1 is provided with a number of wall plate fixing holes 13. The upper end face of the flip bracket 2 is provided with a number of load mounting holes 21. The load mounting holes 21 are arranged in a circumferential array in four groups. The load mounting holes 21 are located on the bearing protrusions on the end face of the flip bracket 2. The flip bracket 2 is symmetrically provided with connecting lugs 22. The connecting lugs 22 are located on the opposite side of the locking tongue 5. The servo motor 32 is connected to a trigger 10 via a wireless module signal. The trigger 10 is a local controller or a smart terminal. In this embodiment, the flip bracket 2 is a single part, which is processed by machining or 3D printing to adopt a semi-enclosed integrated frame structure. The opening direction and shape depend on the load function, and the weight should be reduced as much as possible while meeting the structural rigidity requirements. The upper surface of the flip bracket 2 is the support surface of the cabin frame 1 and also the flip surface after triggering. A circular load mounting hole 21 is set in the middle of the flip surface for load mounting. After triggering, the flip bracket 2 flips together with the load. The locking tongue 5 is connected to the side of the flip bracket 2 facing the opening direction and is used for connecting and unlocking the cabin frame 1 and the flip bracket 2. The connecting lug 22 is set on the other side opposite to the side where the locking tongue 5 is located, and its outer side is connected to the inner side of the connecting seat 12 on the cabin frame 1 for connecting and flipping the cabin frame 1 and the flip bracket 2.

[0022] The torque connection assembly 7 includes a torsion spring 71, a cylindrical sleeve 72, and a bolt 73. After the connecting seat 12 is aligned with the connecting lug 22, the bolt 73 is inserted. The cylindrical sleeve 72 is sleeved on the bolt 73, and both ends of the cylindrical sleeve 72 are embedded in the connecting lug 22. The torsion spring 71 is sleeved on the cylindrical sleeve 72, and the torsion arm of the torsion spring 71 abuts against the arcuate groove 121 of the connecting seat 12. The torsion spring 71 is a double torsion spring, and two sets of arcuate grooves 121 are arranged side by side on the connecting seat 12. In this embodiment, the arc groove 121 is semi-circular, the connecting seat 12 is provided with a first through hole, and the connecting lug 22 is provided with a second through hole. After the first through hole and the second through hole are aligned on the same axis, the bolt 73 is inserted. The bolt 73 passes through the two connecting lugs 22 from one side of the connecting seat 12, and passes through the cylindrical sleeve. It is then fixed to the other side of the connecting seat 12 by threads. The torque connection assembly is provided between the cabin frame 1 and the tilting bracket 2 to realize the hinge connection between the cabin frame 1 and the tilting bracket 2.

[0023] When unlocking, the servo motor 32 receives a trigger command signal or a remote control command signal transmitted by the trigger 10. The servo motor 32 drives one end of the first connecting rod 33 to rotate, and the other end of the first connecting rod 33 drives the lock cylinder rod 6 to be pulled out from the lock tongue 5, so that the flip bracket 2 can automatically flip at the bottom of the cabin frame 1.

[0024] In one embodiment, the flip bracket 2 is hinged to the bottom of the cabin frame 1 on one side and connected to the cabin frame 1 on the other side through the trigger unlocking assembly. The latch 5 is provided with a lock cylinder insertion hole 51 that is adapted to the lock cylinder rod 6. The trigger 10 adopts a smart terminal. When the servo receives the trigger command signal or remote control command signal transmitted by the controller, it triggers the transmission mechanism to pull out the lock cylinder rod 6, thereby realizing trigger unlocking. The flip bracket 2 achieves flipping at the bottom of the cabin frame 1 through the principle of gravity.

[0025] In another embodiment, a torsion connection assembly 7 is provided on one side of the connection between the flip bracket 2 and the cabin frame 1, and the other side is connected to the cabin frame 1 through the trigger unlocking assembly. Before triggering, the torsion spring 71 in the torsion connection assembly 7 has elastic potential energy due to deformation. After the trigger unlocking assembly is triggered and unlocked, the elastic potential energy of the torsion spring 71 is converted into the kinetic energy of the flip bracket 2 and the fixed load on it. With its own gravity, the flip bracket 2 can be quickly flipped open at the bottom of the cabin frame 1 without relying on any external force. After unlocking and flipping, it can be manually restored. When manually restored, the locking tongue 5 on the flip bracket 2 is engaged with the lock body 4, and the servo motor 32 drives the lock cylinder rod 6 to pass through the lock body 4 and insert into the locking tongue 5.

[0026] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
