[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] A shock-absorbing structure for a surveying drone 1 includes the drone 1. The bottom of the drone 1 has support legs 2 and a housing 3. A U-shaped frame 4 is located at the other end of the support legs 2. First grooves 22 are formed inside both ends of the U-shaped frame 4, and I-shaped legs 5 are engaged in the first grooves 22. A support rod 6 is welded to the bottom of the U-shaped frame 4. A movable plate 7 is sleeved on the outer surface of the support rod 6. Both ends of the movable plate 7 are rotatably connected to connecting rods 8 via pins. A first T-shaped groove is formed inside the I-shaped leg 5 near its top, and a locking block 9 is engaged in the first T-shaped groove. A first spring 14 and a second spring 15 are sleeved on the outer surface of the support rod 6. One end of the first spring 14 abuts against the top of the movable plate 7, and one end of the second spring 15 abuts against the bottom of the movable plate 7. The I-shaped legs 5... A second through hole is opened inside the top wall, and the support rod 6 is inserted into the second through hole. A guide rod 16 is set inside the top wall of the I-shaped support leg 5. The locking block 9 is welded to the outer surface of the guide rod 16. The other end of the connecting rod 8 is rotatably connected to the slider 17 through the pin. The slider 17 is sleeved on the outer surface of the guide rod 16. A damper 18 is set on the top of the locking block 9. The other end of the damper 18 is set at the bottom of the top wall of the U-shaped frame 4. A third spring 19 is sleeved on the outer surface of the damper 18. One end of the third spring 19 abuts against the top of the locking block 9, and the other end of the third spring 19 abuts against the bottom of the top wall of the U-shaped frame 4. A fourth spring 20 is sleeved on the outer surface of the guide rod 16. One end of the fourth spring 20 abuts against the locking block 9, and the other end of the fourth spring 20 abuts against the slider 17.

[0028] To achieve the desired shock absorption effect in this type of surveying drone's vibration damping structure, which can reduce the impact force experienced by the surveying drone during landing, as shown in the attached figure... Figure 1-4 As shown, this application adopts the following structure: through the cooperation of the drone 1, I-shaped legs 5, first slide groove 22, support rod 6, damper 18, third spring 19, slider 17, connecting rod 8, moving plate 7, first spring 14, second spring 15 and fourth spring 20, during use, after the surveying drone 1 completes the survey, it lands on the ground or a designated area. When the I-shaped legs 5 contact the ground, they are subjected to a certain impact force, causing them to move upward along the direction of the first slide groove 22 and the support rod 6. During the upward movement of the I-shaped legs 5, the damper 18 and the third spring 19 sleeved on the outer surface of the damper 18 are compressed, reducing the impact. The slider 17 moves upward with the I-shaped legs 5 and pushes the connecting rod 8. The force causes the connecting rod 8 to push the moving plate 7. The moving plate 7 moves upward along the support rod 6 and squeezes the first spring 14, further reducing the impact. The I-shaped support leg 5 continues to move along the direction of the first slide groove 22 and the support rod 6. When the first spring 14 is squeezed to a certain extent, the first spring 14 gives the moving plate 7 a push force, while the second spring 15 gives the moving plate 7 a pull force, causing the moving plate 7 to move downward along the support rod 6 and give the connecting rod 8 a push force. The connecting rod 8 pushes the slider 17, causing the slider 17 to move along the direction of the guide rod 16 and squeeze the fourth spring 20, further improving the shock absorption effect. Thus, this shock absorption structure for surveying UAVs has a good shock absorption effect and can reduce the impact force on the surveying UAV when it lands.

[0029] Example 2

[0030] A shock-absorbing structure for a surveying drone 1 includes a card box 3 with a square groove inside. The left and right walls of the card box 3 each have a first through hole. A pull rod 10, adapted to the inner diameter of the first through hole, is installed in the first through hole. A baffle 11 is welded to the outer surface of the pull rod 10. The card box 3 has a second T-shaped groove inside, in which a connecting frame 12 is engaged. A surveying camera 13 is engaged inside the connecting frame 12. A third through hole is located near the top of the connecting frame 12, with an inner diameter slightly larger than the diameter of the pull rod 10. The left and right walls of the card box 3 have second sliding grooves inside, in which the baffle 11 is engaged. A fifth spring 21 is installed on one side of the baffle 11, and the other end of the fifth spring 21 is located on the inner wall of the card box 3.

[0031] To achieve the effect of facilitating quick and easy installation and removal of the surveying camera in this type of shock-absorbing structure for surveying drones, as shown in the attached document... Figure 5-6As shown, this application adopts the following structure. Through the cooperation of the pull rod 10, baffle 11, fifth spring 21, card box 3 and connecting frame 12, during use, when installing the detection camera, first pull the pull rod 10. The pull rod 10 drives the baffle 11 to move and squeeze the fifth spring 21. Then, the connecting frame 12 is inserted into the second T-shaped groove inside the card box 3. Release the pull rod 10. The fifth spring 21 releases its elastic force and pushes the baffle 11 and the pull rod 10. The baffle 11 moves along the second sliding groove and drives the pull rod 10, so that the pull rod 10 enters the third through hole inside the connecting frame 12 to fix the connecting frame 12. Similarly, when the surveying camera 13 needs to be disassembled, pull the pull rod 10. The pull rod 10 drives the baffle 11 to move, so that the pull rod 10 disengages from the third through hole inside the connecting frame 12. The connecting frame 13 and the surveying camera 14 can be removed. Thus, this shock-absorbing structure for surveying UAVs has the effect of facilitating quick installation and disassembly of the surveying camera.
