Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides two technical solutions:

[0024] Embodiment 1

[0025] A racing drone with a clamping structure includes a drone body 1, a battery is installed inside the drone body 1, a buffer mechanism 2 is provided at the bottom of the drone body 1, and a clamping mechanism 3 is provided at the bottom of the drone body 1. The clamping mechanism 3 includes:

[0026] The clamping assembly 31 includes a device box 311 installed at the bottom of the drone body 1. The inner wall of the device box 311 is slidably connected with a sliding plate 312. The inner wall of the device box 311 is provided with a slide groove for the sliding plate 312 to slide. The two sides of the sliding plate 312 are connected by the transmission assembly 4 to make the folding rod 313 slide. The device box 311 is a bottom-opening box. One end of the folding rod 313 is fixedly connected with a clamping block 314 by bolts.

[0027] The driving assembly 32 is arranged inside the equipment box 311. The transmission assembly 4 includes a transmission rod 41 rotatably installed on the inner wall of the equipment box 311 and a connecting rod 42 rotatably installed on both sides of the sliding plate 312. One end of the transmission rod 41 is rotatably connected to a rotating rod 43. One end of the rotating rod 43 is rotatably connected to the inside of the sliding plate 312. The other end of the rotating rod 43 is rotatably connected to one end of the folding rod 313. One end of the connecting rod 42 is rotatably connected to the inside of the folding rod 313. The driving assembly 32 includes a driving motor 321 installed at the bottom of the inner cavity of the drone body 1. The driving motor 321 is installed inside the drone body 1. The driving motor 321 is connected to the battery through an electric wire. One end of the output shaft of the driving motor 321 is fixedly connected to a screw rod 322 through a coupling. The screw rod 322 rotates inside the equipment box 311. The surface of the screw rod 322 is connected to the inner cavity of the sliding plate 312. The screw rod 322 is threadedly connected to the device box 311, and the screw rod 322 is driven to rotate by starting the driving motor 321. The rotation of the screw rod 322 makes the sliding plate 312 slide on the inner surface of the sliding groove opened on the inner wall of the device box 311. The sliding of the sliding plate 312 makes one end of the rotating rod 43 and the connecting rod 42 rotate inside the sliding plate 312, and the other ends of the rotating rod 43 and the connecting rod 42 rotate inside the folding rod 313, so that one end of the transmission rod 41 rotates on the inner wall of the device box 311, and the other end of the transmission rod 41 rotates on the surface of the rotating rod 43, so that the folding rod 313 and the clamping block 314 on both sides slide to the opposite side synchronously, so as to clamp the object. By providing the clamping mechanism 3, the rapid clamping of the object or heavy object is realized, so that the competition drone can remain stable in the subsequent load-bearing flight competition, thereby avoiding the situation where the object or heavy object slips in the middle of the load-bearing flight competition.

[0028] Embodiment 2

[0029] The main difference from the first embodiment is:

[0030] A racing drone with a clamping structure, wherein a buffer mechanism 2 includes a connecting plate 21 installed at the bottom of a drone body 1, a sliding block 22 is slidably connected inside the connecting plate 21, a buffer spring 23 is fixedly connected to one side of the sliding block 22, one end of the buffer spring 23 is fixedly connected to the inner wall of the connecting plate 21, a buffer plate 24 is fixedly connected to the surface of the sliding block 22 through a linkage component 5, a buffer pad is installed at the bottom of the buffer plate 24, and the linkage component 5 includes a linkage column 51 installed at the top of the buffer plate 24, a linkage rod 52 is slidably connected inside the linkage column 51, and the top of the linkage rod 52 is fixed to the inner wall of the connecting plate 21. The bottom is fixedly connected, and the surface of the linkage column 51 is rotatably connected with a buffer rod 53, one end of the buffer rod 53 is rotatably connected to the surface of the sliding block 22, and a damper 6 is installed at the bottom of the inner cavity of the linkage column 51. The damper 6 is a prior art. The damper 6 is installed inside the four linkage columns 51, and the top of the damper 6 is fixedly connected to the bottom end of the linkage rod 52. By providing a buffer mechanism 2, the impact force generated by the competition drone when falling is absorbed and buffered, thereby improving the stability of the drone after landing. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] During operation, the driving motor 321 is started to drive the screw rod 322 to rotate. The rotation of the screw rod 322 causes the sliding plate 312 to slide on the inner surface of the slide groove opened on the inner wall of the equipment box 311. The sliding of the sliding plate 312 causes one end of the rotating rod 43 and the connecting rod 42 to rotate inside the sliding plate 312, and the other ends of the rotating rod 43 and the connecting rod 42 rotate inside the folding rod 313, so that one end of the transmission rod 41 rotates on the inner wall of the equipment box 311, and the other end of the transmission rod 41 rotates on the surface of the rotating rod 43, so that the folding rod 313 and the clamping block 314 on both sides slide to the opposite side synchronously, so as to clamp the object, so that no one can move. The machine maintains the stability of the object in the subsequent load-bearing flight competition. When the drone lands, the buffer pad installed at the bottom of the buffer plate 24 first contacts the ground, and then the linkage rod 52 slides inside the linkage column 51, and the force is buffered by the damper 6. When the linkage rod 52 slides inside the linkage column 51, one end of the buffer rod 53 rotates on the surface of the linkage column 51, and the other end of the buffer rod 53 rotates on the surface of the sliding block 22, so that the two sliding blocks 22 slide relative to each other inside the connecting plate 21, thereby compressing the buffer spring 23, and the buffer spring 23 further buffers the force, thereby maintaining the stability of the drone after landing.
