[0053] Please see Figure 1-5 This utility model provides a technical solution: a collision avoidance device for geographic information mapping drones, comprising:

[0054] The drone 1 is equipped with four rotors, and the drone 1 flies stably by using the four rotors;

[0055] The mapping camera 7 is mounted on the middle of the bottom surface of the UAV 1. The mapping camera 7 serves as the geographic information mapping camera in this embodiment.

[0056] The four rotors of the drone 1 are equipped with shock-absorbing ring-shaped protective frames 6, and the mapping camera 7 is located in the middle of the shock-absorbing ring-shaped protective frame 6, which provides shielding and anti-collision protection for the mapping camera 7. When the drone 1 lands, the shock-absorbing ring-shaped protective frame 6 acts as a landing gear with shock absorption function and contacts the ground.

[0057] After compression, the height of the shock-absorbing ring-shaped protective frame 6 is greater than that of the surveying camera 7. When the shock-absorbing ring-shaped protective frame 6 is impacted and compressed in height upon contact with the ground, the lower end of the surveying camera 7 is kept at a sufficient height from the bottom surface to prevent the surveying camera 7 from contacting the ground. At the same time, when landing, a flat ground is selected to prevent the lower end of the surveying camera 7 from hitting protruding stones or other debris.

[0058] Connectors 2 are attached and fixed to the outer walls of the four rotors of the UAV 1, and ring-shaped protective rings 3 are attached and fixed to the outer ends of the four connectors 2.

[0059] The strip-shaped inflatable belt 4 is wrapped around the outer wall of the annular protective ring 3. The outer walls of the four rotors of the UAV 1 are fixed to the annular protective ring 3 through the connector 2 to shield and protect the UAV 1. The strip-shaped inflatable belt 4 wrapped around the outer wall of the annular protective ring 3 provides an elastic cushioning effect, enhances the anti-collision performance of the annular protective ring 3, and provides better protection for the UAV 1 and the mapping camera 7, which is a geographic information mapping camera.

[0060] In some embodiments, in order to shield and protect the mapping camera 7, provide collision protection, and serve as a shock-absorbing landing gear when the drone 1 lands, the shock-absorbing ring-shaped protective frame 6 includes:

[0061] The aluminum alloy upper ring 61 runs through the four rotor supports of the UAV 1;

[0062] The bottom surface of the aluminum alloy upper ring 61 is uniformly and vertically fixed with elastic support rods 63;

[0063] The lower aluminum alloy ring 62 is fixedly connected to the lower end of the elastic support rod 63. The upper aluminum alloy ring 61 and the lower aluminum alloy ring 62 are made of aluminum alloy, which has the characteristics of being lightweight and high-strength, meeting the assembly requirements of UAVs. The lower aluminum alloy ring 62 improves the stability of the landing gear compared to traditional landing gear when in contact with the ground. The elastic support rods 63, which are evenly distributed between the upper aluminum alloy ring 61 and the lower aluminum alloy ring 62, deform and provide elastic buffering when subjected to impact, thus playing a shock absorption role.

[0064] In some embodiments, in order to provide elastic shock absorption when the shock-absorbing ring-shaped protective frame 6 contacts the ground, the elastic support rod 63 includes:

[0065] A cylinder 631, the upper end of which is fixedly connected to the bottom surface of an aluminum alloy upper ring 61;

[0066] The cylindrical body 632 is vertically and fixedly connected to the upper surface of the aluminum alloy upper ring 61, corresponding to the cylindrical body 631.

[0067] A round rod 633 is fixedly connected to the middle of the bottom surface of the cylinder 631, and its lower end is slidably inserted into the upper end of the inner cavity of the cylinder 632.

[0068] A spring 634 is longitudinally fixedly connected to the bottom surface of the round rod 633 and the upper surface of the aluminum alloy upper ring 61.

[0069] Upon impact, the cylindrical rod 633 on the cylinder 631 inserts into the cylinder 632 and compresses the spring 634 to contract. The elastic deformation of the spring 634 buffers the impact. The spring 634 extends and retracts along the inner wall of the cylinder 632. The cylinder 632 guides the spring 634 to ensure the shock absorption effect.

[0070] In some embodiments, in order to facilitate the assembly of the shock-absorbing ring-shaped protective frame 6 with the drone 1, the outer walls of the four rotors of the drone 1 are provided with through holes 5 in the horizontal direction, and the aluminum alloy upper ring 61 passes through the four through holes 5.

[0071] In some embodiments, in order to stably position the installation position of the shock-absorbing ring protective frame 6 and avoid inconvenience caused by displacement of the shock-absorbing ring protective frame 6, a steel ring 51 is welded to the inner ring surface of the through hole 5;

[0072] The outer wall of the aluminum alloy upper ring 61 is interference-fitted with the inner wall of the steel ring 51.

[0073] In some embodiments, in order to disperse the impact force through the hinged deformation between the quarter-ring bodies 31 after being subjected to impact, the annular protective ring 3 includes:

[0074] There are four quarter-ring bodies (31 in total).

[0075] Four quarter-ring bodies 31 are fixedly connected by hinges 32 at their ends;

[0076] The quarter ring 31 corresponds one-to-one with the four connectors 2, and the quarter ring 31 is glued and fixed to the outer end of the corresponding connector 2;

[0077] The strip-shaped inflatable band 4 is wrapped around and connected to the outer wall of the four quarter-ring bodies 31.

[0078] In some embodiments, in order to allow disassembly and installation on the outer walls of the four quarter-ring bodies 31 that are hinged together at both ends, and to provide cushioning against impacts, the auxiliary annular protective ring 3, and the strip-shaped inflatable belt 4, include:

[0079] An inflatable belt body 41 has a connecting belt 43 fixedly connected to one end;

[0080] A strip connecting groove 42 is provided on the outer wall of the other end of the inflatable belt 41 corresponding to the connecting belt 43;

[0081] The rear wall of the connecting strip 43 is glued with a hook side, and the bottom surface of the strip connecting groove 42 is glued with a hook side.

[0082] The connecting strap 43 is attached to the strip connecting groove 42, and the inflatable strap 41 is wrapped around the outer wall of the four quarter rings 31. The Velcro is convenient for disassembly and installation.

[0083] In some embodiments, in order to position the inflatable belt 41 and prevent it from being affected by displacement after being impacted, an arc-shaped groove 33 is provided in the middle of the outer wall of the quarter ring 31 along the length direction.

[0084] The inflatable belt 41 is wound around and connected to the arc-shaped grooves 33 on the outer wall of the four quarter-ring bodies 31.

[0085] In some embodiments, in order to cushion the impact force after being subjected to an impact by inflating the strip-shaped flexible airbag 412, the inflatable band 41 includes:

[0086] A strip-shaped sleeve 411, into which a strip-shaped flexible airbag 412 is inserted;

[0087] The outer wall of the strip-shaped flexible airbag 412 is provided with an air nozzle 413, and the outer end of the air nozzle 413 extends through to the outer side of the strip-shaped sleeve 411.

[0088] In some embodiments, in order to assist the annular protective ring 3 and the strip-shaped inflatable belt 4 in providing elastic cushioning against impact, the connector 2 is specifically an elastic rubber rod.

[0089] Working principle:

[0090] The four rotors of the drone 1 are equipped with shock-absorbing ring-shaped protective frames 6, and the surveying camera 7 is located in the middle of the shock-absorbing ring-shaped protective frames 6, which provides shielding and anti-collision protection for the surveying camera 7. When the drone 1 lands, the shock-absorbing ring-shaped protective frames 6 act as a landing gear with shock absorption function and contact the ground. After the shock-absorbing ring-shaped protective frames 6 are compressed, their height is greater than that of the surveying camera 7. After the shock-absorbing ring-shaped protective frames 6 are impacted and compressed in height upon contact with the ground, the lower end of the surveying camera 7 is left with sufficient height from the bottom surface to avoid the surveying camera 7 from contacting the ground. At the same time, the landing is on a flat ground to avoid the lower end of the surveying camera 7 hitting protruding stones or other debris.

[0091] The outer walls of the four rotors of the UAV 1 are fixed with annular protective rings 3 by connectors 2 to shield and protect the UAV 1. Strip-shaped inflatable belts 4 are wrapped around the outer walls of the annular protective rings 3 to provide elastic cushioning and enhance the anti-collision performance of the annular protective rings 3, thus providing better protection for the UAV 1 and the mapping camera 7, which serves as a geographic information mapping camera.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
