Description

Technical Field

[0001] This patent relates to the technical field of UAV protection, and specifically to an anti-collision structure for UAVs. Background Art

[0002] Currently, the applications of UAVs are involved in aerial photography, agriculture, plant protection, disaster relief and other fields. During the flight of UAVs, they may collide with obstacles. Especially, the high-speed rotating rotors are easily damaged due to collisions. Therefore, existing UAVs generally set protective bars outside the rotors to avoid damage to the rotors caused by collisions.

[0003] However, existing anti-collision structures of UAVs are all set outside the rotors, which can only protect the rotors. When a UAV collides, the UAV is also prone to rollover and other situations, resulting in wear on the upper and lower walls of the UAV, affecting its appearance, and even the battery pack may be knocked off.

[0004] Patent Content

[0005] The purpose of this patent is to provide an anti-collision structure for UAVs to solve the problems raised in the above background art.

[0006] To achieve the above purpose, this patent provides the following technical solution: an anti-collision structure for UAVs, including a UAV main body and a protective fence. The protective fence is installed outside the UAV main body, and the protective fence can protect the UAV main body. A buffer mechanism is installed outside the protective fence.

[0007] The buffer mechanism includes a rubber strip, a cavity, a frame, a chute, and a side protection plate. A cavity is opened inside the rubber strip, and a frame is inserted and installed in the cavity. The rubber strip is attached and installed outside the protective fence. A chute is opened on the upper wall of the frame, and the side protection plate is inserted and installed in the chute. The side protection plate can slide up and down in the chute.

[0008] The upper and lower ends of the side protection plate are respectively located on the upper and lower sides of the UAV main body.

[0009] Preferably, a groove is opened on the side wall of the side protection plate, a threaded hole is opened on the side wall of the frame, and a bolt is screwed and installed in the threaded hole. The bolt passes through the side wall of the frame through the threaded hole and is inserted into the groove.

[0010] Preferably, spring grooves are opened at both the upper and lower ends of the inner side wall of the groove, springs are inserted and installed in the spring grooves, and a top block is installed at one end of the spring outside the spring groove. The top block can be attached to the outer side wall of the bolt.

[0011] Preferably, the UAV body includes a fuselage, cantilevers, rotors, a battery pack and a camera pan-tilt. Cantilevers are installed on both the left and right sides of the fuselage. There are four cantilevers in total, and rotors are installed at the upper ends of the four cantilevers. A battery slot is provided on the upper wall of the fuselage, and the battery pack is inserted and installed in the battery slot. The battery pack is electrically connected to the fuselage. A camera pan-tilt is rotatably installed on the side wall of the fuselage, and the camera pan-tilt is electrically connected to the fuselage.

[0012] Preferably, a spherical groove is provided at one end of the bolt located in the groove, and a sphere is installed in the spherical groove, and the sphere can be attached to the inner wall of the groove.

[0013] Preferably, a protective frame is installed on the side wall of the fuselage, and the protective frame is arranged outside the camera pan-tilt.

[0014] Compared with the prior art, the beneficial effects of this patent are:

[0015] The device protects the rotors of the UAV body by setting a protective fence, and a rubber strip and a side protection plate are also arranged outside the protective fence. When a collision occurs, the rubber strip first contacts the external obstacle, and through the buffering of the rubber strip, the damage caused by the collision impact to the UAV body is reduced. In addition, the height of the side protection plate is higher than the height of the UAV body, so that when the UAV body rolls over or flips, the side protection plate can prevent the UAV body from contacting the external ground or obstacles, and avoid abrasion of the UAV body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of this patent in conjunction with the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0021] Please refer to Figure 1-2 , this patent provides a technical solution: an anti-collision structure for a drone, including a drone main body 1 and a guardrail 2. The guardrail 2 is installed on the outside of the drone main body 1, and the guardrail 2 can protect the drone main body 1. A buffer mechanism 3 is installed on the outside of the guardrail 2;

[0022] The buffer mechanism 3 can provide buffering when the drone main body 1 collides, avoiding the direct hard contact of the drone main body 1 with external obstacles and reducing the damage to the drone main body 1 caused by the collision;

[0023] The buffer mechanism 3 includes a rubber strip 31, a cavity 32, a frame body 33, a chute 34, and a side protection plate 35. A cavity 32 is opened inside the rubber strip 31, and the frame body 33 is inserted and installed in the cavity 32. The rubber strip 31 is fitted and installed on the outside of the guardrail 2. A chute 34 is opened on the upper wall of the frame body 33, and the side protection plate 35 is inserted and installed in the chute 34. The side protection plate 35 can slide up and down in the chute 34;

[0024] The upper and lower ends of the side protection plate 35 are respectively located on the upper and lower sides of the drone main body 1;

[0025] In this article, the proposed frame body 33 is made of aluminum alloy to reduce the load on the drone main body 1. Because the rubber has good buffering performance, a rubber strip 31 is provided in a circle on the outside of the guardrail 2 of this device, so that when a collision occurs, the rubber strip 31 can absorb the impact force generated by the impact and avoid damage to the drone main body 1;

[0026] In addition, the upper and lower ends of the side protection plate 35 are respectively higher than the upper wall and the lower wall of the drone main body 1. If the drone main body 1 explodes and falls, the side protection plate 35 can ensure that the drone main body 1 does not directly contact the ground and avoid abrasion.

[0027] Specifically, a groove 4 is opened on the side wall of the side protection plate 35, a threaded hole 5 is opened on the side wall of the frame body 33, and a bolt 6 is screwed and installed in the threaded hole 5. The bolt 6 passes through the side wall of the frame body 33 through the threaded hole 5 and is inserted into the groove 4;

[0028] When the side protection plate 35 is damaged, the bolt 6 can be rotated to make the bolt 6 leave the groove 4, and then the side protection plate 35 can be taken out of the chute 34 for replacement.

[0029] Specifically, spring grooves 7 are provided at both the upper and lower ends of the inner side wall of the groove 4. Springs 8 are inserted and installed in the spring grooves 7. A top block 9 is installed at one end of the spring 8 outside the spring groove 7, and the top block 9 can be attached to the outer side wall of the bolt 6.

[0030] The function of the spring 8 is to enable the side protection plate 35 to reset. When being impacted, the side protection plate 35 will slide in the sliding groove 34. After the impact occurs, under the action of the spring 8, the side protection plate 35 will reset to the starting position.

[0031] Specifically, the UAV main body 1 includes a fuselage 10, cantilevers 11, rotors 12, a battery pack 13 and a camera pan-tilt 14. Cantilevers 11 are installed on both the left and right sides of the fuselage 10. There are four cantilevers 11 in total, and rotors 12 are installed at the upper ends of the four cantilevers 11. A battery slot 15 is provided on the upper wall of the fuselage 1. The battery pack 13 is inserted and installed in the battery slot 15, and the battery pack 13 is electrically connected to the fuselage 10. A camera pan-tilt 14 is rotatably installed on the side wall of the fuselage 10, and the camera pan-tilt 14 is electrically connected to the fuselage 10.

[0032] Specifically, a spherical groove 16 is provided at one end of the bolt 6 located in the groove 4, and a sphere 17 is installed in the spherical groove 16. The sphere 17 can be attached to the inner wall of the groove 4.

[0033] By providing the sphere 17, the friction between the bolt 6 and the groove 4 can be reduced.

[0034] Specifically, a protective frame 18 is installed on the side wall of the fuselage 10, and the protective frame 18 is arranged outside the camera pan-tilt 14.

[0035] The protective frame 18 can protect the camera pan-tilt 14 and prevent the camera pan-tilt 14 from being damaged due to collision.

[0036] Working principle: When the UAV main body 1 collides, the rubber strip 31 can absorb the impact force generated by the impact and prevent the UAV main body 1 from being damaged.

[0037] In addition, if the flight attitude of the UAV main body 1 is damaged due to collision and a crash occurs, the UAV main body 1 will directly fall to the ground below. At this time, the side protection plate 35 in this device can ensure that the UAV main body 1 does not directly contact the ground and avoid abrasion.
