[0002] Mine drone surveying is a technical means that uses drones equipped with professional sensors to perform tasks such as surveying, monitoring, and exploration in mining scenarios. The core is to use the drones' flexible flight and data collection capabilities to efficiently acquire spatial information of the mine and transform it into usable data, providing support for mine planning, production, and safety management.

[0003] However, traditional drone brackets are mostly rigid structures or simple rubber pads for cushioning, which can only cope with slight vibrations and are difficult to withstand the severe impacts in the complex environment of mines. This can easily cause problems such as fuselage deformation, broken measuring camera lenses, and malfunctions of lidar sensors. Not only are maintenance costs high, but measurement operations can also be interrupted. Therefore, it is necessary to design a shockproof bracket for mine drone measurement to solve the above problems. Utility Model Content

[0014] 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.

[0015] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a fall-proof bracket for measuring with a mining drone, including a mounting plate 1. The mounting plate 1 has waist-shaped mounting holes 2 for fixing to the drone body. The side of the mounting plate 1 is provided with four sets of support legs 3. The bottom of each of the four sets of support legs 3 is connected to a base 5 through a first buffer mechanism. The top two sides of the mounting plate 1 are provided with a surrounding plate 14. One side of each of the two surrounding plates 14 is connected to an elastic plate 21 through a second buffer mechanism.

[0016] Specifically, in use, the anti-fall bracket is first fixed to the body of the mining surveying drone through the waist-shaped mounting holes 2 on the mounting plate 1. When the drone takes off and lands in the mining area or accidentally touches the ground, the first buffer mechanism can absorb the impact energy. Combined with the base 5, it can enhance the support stability and reduce the transmission of impact to the body. If the drone rolls over or collides with the side, the second buffer mechanism on one side of the enclosure 14 can drive the elastic plate 21 to contact the collision object first. The second buffer mechanism can further buffer the lateral impact force, while the elastic plate 21 avoids direct rigid contact between the enclosure 14 and the body. Thus, through the synergistic effect of the first buffer mechanism, the second buffer mechanism and the elastic plate 21, all-round anti-fall protection for the mining surveying drone can be achieved, which has the beneficial effects of strong adaptability, good buffering effect and comprehensive protection.

[0017] The first buffer mechanism includes a first spring 10. A connecting seat 4 is located at the bottom of the support leg 3. One end of the base 5 passes through the inner bottom of the connecting seat 4. Two sets of limiting grooves 6 are symmetrically opened on the side of the base 5. A protrusion that slides through the limiting groove 6 is located on the inner wall of the connecting seat 4. A fixing rod 7 is located near the top of the inner side of the connecting seat 4, and a fixing block 8 is located in the center of the rod. Two sets of sliding sleeves 9 are slidably connected to the outer ring of the fixing rod 7. One end of each set of sliding sleeves 9 is connected to both sides of the fixing block 8 via the first spring 10. A hinge arm 11 is hinged to the bottom of each set of sliding sleeves 9. The other end of each set of hinge arms 11 is hinged to the top of the base 5. Four sets of first dampers 12 are evenly arranged circumferentially on the top of the base 5, one end of which is connected to the top inner side of the connecting seat 4. The outer ring of each of the first dampers 12 is fitted with a second spring 13. When the UAV takes off or lands and touches the ground or crashes accidentally, the base 5 is pressed upward by force, which can drive the two sets of hinged arms 11 at its top to rotate. This causes the two sets of sliding sleeves 9 to slide along the fixed rod 7 on the inner side of the connecting seat 4 toward the fixed block 8. At the same time, the first springs 10 on both sides can be compressed. The deformation of the first springs 10 can initially absorb the vertical impact energy. Meanwhile, the four sets of first dampers 12 at the top of the base 5 contract synchronously, which can slow down the impact speed. The second springs 13 on their outer ring can further assist in absorbing the impact energy. Thus, through the synergistic effect of the first springs 10, the first dampers 12 and the second springs 13, the vertical impact force can be effectively buffered, protecting the UAV body and measuring components.

[0018] The top of the connecting seat 4 is threaded to the support leg 3, and the bottom of the base 5 is glued with a shock-absorbing pad. The connection between the top of the connecting seat 4 and the support leg 3 allows for easy disassembly and replacement of the first buffer mechanism components as needed. The shock-absorbing pad glued to the bottom of the base 5 can further enhance the buffering effect when in contact with the ground, reduce vibration transmission, and provide the beneficial effects of convenient disassembly and assembly and more comprehensive buffer protection.

[0019] The second buffer mechanism includes a third spring 19. Grooves 15 are provided on one side of the enclosure 14 near both ends. Two sets of sliding rods 16 are provided inside each of the two sets of grooves 15 and slidably connected to sliding blocks 17. One side of each set of sliding blocks 17 is connected to the inner wall of one side of the groove 15 via a second damper 18. The outer ring of each set of second dampers 18 is fitted with a third spring 19. One end of each set of sliding blocks 17 is hinged to one end of the scissor arm 20, and the other end of the scissor arm 20 is hinged to one side of the elastic plate 21. When the drone rolls over or collides sideways, the elastic plate 21 can first contact the colliding object. Upon contact and force application, the scissor arm 20, which is hinged to it, retracts. The two ends of the scissor arm 20 can push the two sets of slide blocks 17 in the groove 15 of the enclosure 14 to slide along the slide rod 16. During the sliding process, the slide blocks 17 can compress the second damper 18 and the third spring 19 on its outer ring. The second damper 18 can reduce the impact speed through damping, and the deformation of the third spring 19 can absorb the lateral impact energy. Thus, through the synergistic effect of the scissor arm 20, the second damper 18 and the third spring 19, the lateral impact force can be buffered, preventing the collision force from being directly transmitted to the enclosure 14 and the drone fuselage.

[0020] Among them, the elastic plate 21 is arc-shaped, and a buffer pad is bonded to its outer side. The arc-shaped design of the elastic plate 21 can disperse the force during side collisions, and the buffer pad bonded to its outer side can further absorb the collision energy and avoid rigid contact. The dual function enhances the side protection effect and reduces damage to the drone fuselage.

[0021] Working principle: First, the anti-fall bracket is fixed to the body of the mining surveying drone through the waist-shaped mounting holes 2 on the mounting plate 1. When the drone takes off and lands in the mining area or accidentally touches the ground, the base 5 inside the bottom connecting seat 4 of the support leg 3 can touch the ground first and be squeezed upwards by force. At the same time, it can drive the two sets of hinged arms 11 at the top to rotate, causing the two sets of sliding sleeves 9 to slide along the fixed rod 7 towards the fixed block 8 and compress the first spring 10. At the same time, the four sets of first dampers 12 at the top of the base 5 contract and the second spring 13 compresses, which can work together to absorb vertical impact energy. The shock-absorbing pad at the bottom of the base 5 can further enhance the cushioning effect. If the drone crashes... In the event of a side rollover or lateral collision, the arc-shaped elastic plate 21 on one side of the top enclosure 14 of the mounting plate 1 can first contact the colliding object, and the outer buffer pad can initially absorb energy. After the elastic plate 21 is subjected to force, it can drive the scissor telescopic arm 20 to retract, thereby pushing the two sets of slide blocks 17 in the groove 15 of the enclosure 14 to slide along the slide rod 16. The slide blocks 17 can squeeze the second damper 18 and the third spring 19. Through the damping effect and spring deformation, the lateral impact can be absorbed. Finally, through the coordinated action of the vertical first buffer mechanism, the lateral second buffer mechanism, and the elastic plate 21, all-round anti-fall protection for the drone can be achieved, thus completing the entire operation process.
