Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a collision avoidance structure for UAVs. Background Technology

[0002] A drone is an unmanned aerial vehicle controlled by remote control or autonomous programs. It mainly consists of an airframe, a power system, a navigation and control system, and a mission payload. According to its purpose, it can be divided into three categories: military, civilian, and consumer. Its advantages include flexibility, low cost, and the ability to perform high-risk missions. It is widely used in disaster relief, logistics and transportation, environmental monitoring and other fields. With the development of 5G and artificial intelligence technologies, drones are evolving towards intelligence and swarming. However, they also face challenges such as airspace management and privacy security, and their development needs to be regulated through laws and technical means.

[0003] During drone operation, operators often accidentally cause the drone's propellers to scrape against tree branches, leaves, or other hard objects due to mistakes or other unforeseen circumstances. Since the drone's propellers are completely exposed, a single accidental scrape can damage the propellers, causing the drone to lose balance and crash. This results in unnecessary economic losses for the operators, thus requiring improvement. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a collision protection structure for drones, which has the advantage of good protection effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a collision avoidance structure for a drone, comprising a drone body, with connecting plates fixedly installed around the drone body, and mounting plates movably connected inside the connecting plates. A first fixing plate and a second fixing plate are fixedly connected to the inner side of the mounting plates, and a mounting ring is fixedly connected between the first fixing plate and the second fixing plate. A sliding block is movably connected to the inner surface of the mounting ring, and a damper is fixedly connected between the sliding blocks. A diagonal rod is hinged to the right end of the sliding block, and a protective plate is hinged to the other end of the diagonal rod.

[0006] As a preferred technical solution of this utility model, a limiting rod is fixedly connected to the inner side of the protective plate, and rectangular plates are fixedly connected to both the front and rear sides of the outer surface of the mounting ring. The interior of the rectangular plates is movably sleeved with the outer surface of the limiting rod.

[0007] As a preferred embodiment of this utility model, a motor is fixedly connected to the top of the connecting plate, and a propeller is fixedly sleeved at the other end of the motor output shaft.

[0008] As a preferred embodiment of the present invention, a rectangular block is fixedly connected to the bottom of the connecting plate, a pull rod is movably sleeved inside the rectangular block, and the other end of the pull rod passes through the rectangular block and extends to the outside of the rectangular block and is fixedly connected to a locking block.

[0009] As a preferred embodiment of this utility model, a movable rod is movably sleeved at the bottom of the connecting plate, and a gear is fixedly sleeved on the outer surface of the movable rod. The outer surface of the gear is engaged with the left side of the locking block.

[0010] As a preferred embodiment of this utility model, a rotating rod is fixedly sleeved on the outer surface of the movable rod, and connecting rods are hinged to both the left and right sides of the rotating rod. The other end of the connecting rod is hinged to the bottom of the mounting plate.

[0011] As a preferred embodiment of this utility model, a spring is movably sleeved on the outer surface of the pull rod, the right side of the spring is fixedly connected to the left side of the rectangular block, and the left end of the spring is fixedly connected to the right side of the locking block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up an installation ring, a sliding block, a damper, a diagonal rod, and a protective plate, causes the protective plate to move to the left when it collides with an external object. This causes the diagonal rod to move and press against the sliding block. Under the limiting action of the installation ring, the sliding block moves away from the damper. At this time, under the damping action of the damper, the movement amplitude of the sliding block is reduced, thereby reducing the movement amplitude of the protective plate. This provides resistance during the collision process, protects the propeller, and improves the service life of the propeller.

[0014] 2. This utility model, by setting up an installation plate, a first fixing plate, a second fixing plate, an installation ring, and a rotating rod, allows the locking block to disengage from the outer surface of the gear when the pulling rod is pulled, thus releasing the fixing effect on the gear and the movable rod. Then, rotating the rotating rod causes the connecting rod to move, and the installation plate, under the limiting action of the connecting plate, moves the first fixing plate and the second fixing plate away from the movable rod, ultimately releasing the fixing effect on the installation ring and achieving the function of easy disassembly and assembly of the protective plate.

[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] like Figures 1 to 5 As shown, this utility model provides a collision avoidance structure for a drone, including a drone body 1. Connecting plates 2 are fixedly installed around the drone body 1. Mounting plates 3 are movably connected inside the connecting plates 2. A first fixing plate 4 and a second fixing plate 5 are fixedly connected to the inner side of the mounting plates 3 respectively. A mounting ring 6 is fixedly connected between the first fixing plate 4 and the second fixing plate 5. A sliding block 7 is movably connected to the inner surface of the mounting ring 6. A damper 8 is fixedly connected between the sliding blocks 7. A diagonal rod 9 is hinged to the right end of the sliding block 7. A protective plate 10 is hinged to the other end of the diagonal rod 9.

[0023] When the protective plate 10 collides with an external object, it will move to the left, causing the diagonal bar 9 to move and press and push the sliding block 7. Under the limiting action of the mounting ring 6, the sliding block 7 will move away from the damper 8. At this time, under the damping action of the damper 8, the movement amplitude of the sliding block 7 will be reduced, thereby reducing the movement amplitude of the protective plate 10 and achieving the resistance effect during the collision.

[0024] Among them, the inner side of the protective plate 10 is fixedly connected to the limiting rod 12, and the front and rear sides of the outer surface of the mounting ring 6 are fixedly connected to the rectangular plate 11. The inside of the rectangular plate 11 is movably sleeved with the outer surface of the limiting rod 12.

[0025] Due to the limiting effect of the rectangular plate 11, the protective plate 10 causes the limiting rod 12 to move horizontally left and right.

[0026] Among them, a motor 13 is fixedly connected to the top of the connecting plate 2, and a propeller 14 is fixedly sleeved at the other end of the output shaft of the motor 13.

[0027] When the operator starts motor 13, the propeller 14 will rotate, which will in turn lift the drone body 1.

[0028] The bottom of the connecting plate 2 is fixedly connected to a rectangular block 15. A pull rod 16 is movably sleeved inside the rectangular block 15. The other end of the pull rod 16 passes through the rectangular block 15 and extends to the outside of the rectangular block 15 and is fixedly connected to a locking block 17.

[0029] When the lever 16 is pulled, the lever 16 will cause the locking block 17 to move horizontally to the right under the limiting action of the rectangular block 15.

[0030] Among them, the bottom of the connecting plate 2 is movably sleeved with a movable rod 19, and the outer surface of the movable rod 19 is fixedly sleeved with a gear 18, and the outer surface of the gear 18 is engaged with the left side of the locking block 17.

[0031] When the locking block 17 disengages from the outer surface of the gear 18, the fixing effect on the gear 18 and the movable rod 19 will be released.

[0032] Among them, a rotating rod 20 is fixedly sleeved on the outer surface of the movable rod 19, and a connecting rod 21 is hinged on both the left and right sides of the rotating rod 20. The other end of the connecting rod 21 is hinged to the bottom of the mounting plate 3.

[0033] When the operator rotates the rotating rod 20, the connecting rod 21 will move, and the mounting plate 3 will drive the first fixing plate 4 and the second fixing plate 5 to move away from the moving rod 19 under the limiting action of the connecting plate 2, thereby releasing the fixing effect on the mounting ring 6.

[0034] Among them, a spring 22 is movably sleeved on the outer surface of the pull rod 16, the right side of the spring 22 is fixedly connected to the left side of the rectangular block 15, and the left end of the spring 22 is fixedly connected to the right side of the locking block 17.

[0035] Due to the design of spring 22, locking block 17 will have a good reset effect during subsequent movement.

[0036] Working principle and usage process of this utility model:

[0037] When an operator accidentally or negligently causes the protective plate 10 to collide with an external object while using the drone body 1, the protective plate 10 will move to the left, causing the diagonal rod 9 to move and press and push the sliding block 7. Under the limiting action of the mounting ring 6, the sliding block 7 will move away from the damper 8. At this time, under the damping action of the damper 8, the movement amplitude of the sliding block 7 will be reduced, thereby reducing the movement amplitude of the protective plate 10. This provides resistance during the collision process, protects the propeller 14, and improves the service life of the propeller 14.

[0038] When the protective plate 10 is damaged by a collision and needs to be disassembled and replaced, pulling the lever 16 will cause the locking block 17 to move to the right, which will cause the locking block 17 to disengage from the outer surface of the gear 18. This will release the fixing effect on the gear 18 and the movable rod 19. Then, rotating the rotating rod 20 will cause the connecting rod 21 to move, and the mounting plate 3 will drive the first fixing plate 4 and the second fixing plate 5 to move away from the movable rod 19 under the limiting action of the connecting plate 2. Finally, the fixing effect on the mounting ring 6 will be released, realizing the function of easy disassembly and assembly of the protective plate 10.
