[0017] 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.

[0018] Please see Figures 1-3This utility model provides a technical solution, including a horizontal plate 1, of which two horizontal plates 1 are provided. Both ends of the two horizontal plates 1 are connected to a cylinder 2. The top of the two cylinders 2 are provided with a fitting groove 3. The bottom end of the horizontal plate 1 is rotatably provided with a bottom buffer assembly 4. The surface of the cylinder 2 is rotatably provided with a fixing assembly 5. Two L-shaped connecting rods 6 are connected to the opposite side of the two horizontal plates 1 and the opposite side of the two cylinders 2. The top of the L-shaped connecting rods 6 is connected to an outer protective plate 7. An arc plate 8 is connected between the close ends of the outer protective plates 7. Multiple second springs 9 are connected to one side of the surface of the arc plate 8. One end of the second spring 9 is connected to an outer collision plate 10.

[0019] The bottom buffer assembly 4 includes two clamping plates 41 connected to the bottom end of the horizontal plate 1. A buffer plate 42 is rotatably disposed between the two clamping plates 41. A buffer spring 43 is connected to one side of the top of the buffer plate 42 below the cylinder 2. A damper 44 is rotatably disposed between the top of the buffer plate 42 and the bottom end of the horizontal plate 1. Its function is that by setting the bottom buffer assembly 4 at the bottom end of the horizontal plate 1, including the buffer plate 42, the buffer spring 43 and the damper 44, when the device is subjected to bottom impact, the buffer plate 42 can rotate, and the buffer spring 43 and the damper 44 work together to effectively absorb and disperse the impact force, protecting the internal structure of the device from damage.

[0020] The fixing component 5 includes a semi-circular locking plate 51 rotatably mounted on one side of the surface of the cylinder 2 and a locking block 52 connected to the other side of the surface of the cylinder 2. The surface of the semi-circular locking plate 51 has a corresponding locking groove 53 for the locking block 52. Its function is to enable quick and convenient installation and disassembly by rotating the semi-circular locking plate 51 on one side of the surface of the cylinder 2 and connecting the locking block 52 on the other side. When the device needs to be fixed, simply rotate the semi-circular locking plate 51 to the position of the locking block 52 and engage the locking block 52 into the locking groove 53 to complete the fixing. Similarly, disassembly is also simple; the device can be easily removed by reversing the operation, greatly improving work efficiency.

[0021] Multiple second springs 9 are arranged in pairs, with the two second springs 9 in each pair arranged vertically. This arrangement connects them to the outer collision plate 10, significantly enhancing structural stability. When subjected to external impact, the vertically arranged springs can share the impact force, reducing the stress on individual springs and thus lowering the risk of spring failure, ensuring that the outer collision plate 10 can stably withstand the impact.

[0022] A reinforcing rod 11 is provided between every two L-shaped connecting rods 6. The reinforcing rod 11 connects multiple L-shaped connecting rods 6 to form a more integrated frame structure. This allows the entire structure to better resist deformation and maintain its geometric shape and relative position when subjected to external forces (such as wind load, motor overload, landing impact, etc.).

[0023] Multiple strip grooves 12 are provided on the surface of the outer protective plate 7 and the arc plate 8. Their function is not only to improve the heat dissipation effect of the device, but also to reduce the overall weight of the structure, thus achieving lightweighting.

[0024] The outer protective plate 7, the arc plate 8, and the outer collision plate 10 are made of carbon fiber reinforced polymer. Their main function is to absorb and disperse collision energy. CFRP has good toughness and energy absorption capacity, and can deform to a certain extent when it is hit, thereby effectively absorbing impact energy, reducing the impact force transmitted to the main structure of the UAV, and playing a buffer protection role.

[0025] Working principle: When the bottom of the drone touches the ground or is subjected to a vertical impact, the buffer plate 42 is compressed and rotates, and the buffer spring 43 is compressed to absorb the vertical impact force, converting kinetic energy into elastic potential energy. Through the damping effect, the rebound speed of the buffer plate 42 is slowed down, avoiding secondary impact, reducing the direct force on the fuselage, and protecting the internal precision equipment. When the side or top of the drone is impacted, the outer collision plate 10 is compressed, and each set of springs 9 arranged vertically is compressed together to disperse the impact force. The elastic deformation of the springs 9 and the plastic deformation of the carbon fiber reinforced polymer absorb energy together, reducing the impact intensity on the fuselage and preventing structural damage. During installation, the landing rod at the bottom of the drone is aligned with the fitting groove 3 and pressed down, and then the snap-fit ​​groove 53 is aligned with the snap-fit ​​block 52. The snap-fit ​​block 52 is inserted into the snap-fit ​​groove 53 to achieve a quick connection between the anti-collision structure and the fuselage.
