[0021] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0022] This application discloses a drone anti-collision device. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0024] like Figure 1 As shown, a drone anti-collision device includes a body 1, characterized in that: an anti-collision mechanism 2 is provided on the outer side of the body 1, and the anti-collision mechanism 2 includes an outer frame 27 for anti-collision.

[0025] Please see Figure 2 The anti-collision mechanism 2 includes a mounting frame 21 fixedly installed on the outside of the main body 1. Ejection boxes 22 are fixedly installed on both sides of the mounting frame 21. Multiple springs 23 are fixedly installed on the inner wall of the ejection box 22. An anti-collision strip 24 is fixedly connected to the other end of the springs 23. The springs 23 are compressed to generate stress on the ejection.

[0026] Please see Figure 2 The ejection box 22 and the anti-collision strip 24 are fixedly installed with a plug slot 25 on one side. The plug slot 25 is inserted with a plug block 26. During flight, if an impact occurs, the plug block 26 is pulled out of the plug slot 25 by impacting the outer frame 27. At the same time as it is pulled out, the compressed spring 23 opens, and the anti-collision strip 24 is ejected instantly to prevent the drone from falling from a height and contacting the ground, which would cause damage to the drone and effectively improve safety.

[0027] Please see Figure 2 A second spring 28 is fixedly installed on the other side of the plug block 26. The other end of the second spring 28 is connected to the main body 1. The outer frame 27 is connected to the plug block 26. The installed second spring 28 is used to generate buffer during impact, so as to avoid direct impact and vibration, which could cause damage and detachment of internal parts of the drone.

[0028] A buffer mechanism 3 is provided on the top of the main body 1. The buffer mechanism 3 includes a mounting plate 34 for buffering.

[0029] Please see Figure 4 The buffer mechanism 3 includes four limiting sleeves 31 fixedly installed on the top of the main body 1. A spring 32 is fixedly installed on the top of the main body 1. A compression column 33 is fixedly connected to the top of the spring 32. The spring 32 and the compression column 33 are located inside the four limiting sleeves 31. If the drone falls backward, the compression column 33 will compress the spring 32 by impacting the mounting plate 34, thereby generating a buffering force to protect the top of the drone and prevent damage to the top, effectively improving the protection of the top.

[0030] Please see Figure 4 The mounting plate 34 is fixedly connected to the top of the extrusion column 33. The extrusion column 33 slides inside the limiting sleeve 31 to limit the movement and prevent the spring 32 from deflecting during impact.

[0031] The bottom of the main body 1 is provided with a surveying mechanism 4, which includes a surveying head 44 for surveying.

[0032] Please see Figure 3 The surveying mechanism 4 includes a mounting block 41 fixedly installed at the bottom of the main body 1. A mounting groove 43 is provided on the front side of the mounting block 41. Rotating columns 42 are rotatably installed on both sides of the inner wall of the mounting groove 43. The surveying head 44 is fixedly installed on one side of the rotating column 42. To further explain, the main body 1 can be used to operate the rotating column 42 to make the surveying head 44 change angles, which is convenient for surveying.

[0033] The installed anti-collision mechanism 2 is used to prevent the drone from falling from a height and making contact with the ground, thus preventing damage to the drone and effectively improving safety. The installed buffer mechanism 3 is used to prevent damage to the top and effectively improve the protection of the top. The installed surveying mechanism 4 is used for drone surveying work.

[0034] The implementation principle of the anti-collision device for unmanned aerial vehicles (UAVs) in this application embodiment is as follows: The installed anti-collision mechanism 2 prevents the UAV from falling from a height and contacting the ground, thus preventing damage and effectively improving safety. The installed buffer mechanism 3 prevents damage to the top, effectively improving top protection. The installed mapping mechanism 4 is used for UAV mapping work. The installed spring 23, in a compressed state, generates stress for ejection. During flight, if an impact occurs, the impact on the outer frame 27 pulls the connector 26 out of the connector slot 25. Simultaneously, the compressed spring 23 expands, causing the anti-collision strip 24 to pop out instantly, preventing the UAV from falling... The drone is designed to withstand impacts from a height, preventing damage. The installed spring 28 acts as a buffer, preventing direct impact and vibration that could damage or dislodge internal parts. During a tip-over fall, the impact on the mounting plate 34 causes the compression column 33 to compress the spring 32, generating a buffer force to protect the top of the drone and prevent damage. The compression column 33 slides within the limiting sleeve 31 to limit movement and prevent the spring 32 from tilting during impact. Furthermore, the main body 1 can be used to operate the rotating column 42, allowing the surveying head 44 to change angles for easier surveying.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
