The lower surface of the drone 5 is provided with a buffer component, which is used to slow down the impact force when the drone 5 lands. The positioning and fixing component includes a motor 31. The motor 31 is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. The output shaft of the motor 31 is fixedly connected with a gear 32. The rear surface of the gear 32 is meshed with a first toothed plate 33, and the front surface of the gear 32 is meshed with a second toothed plate 34. When the gear 32 rotates, it will drive the first toothed plate 33 and the second toothed plate 34 to move towards each other and gradually approach. The upper surface of the first toothed plate 33 is fixedly connected with a connecting block 38. The upper surface of the connecting block 38 is fixedly connected with a first round rod 39. The upper surface of the first round rod 39 is fixedly connected with a first stopper 310. There are two groups of the first stoppers 310, which are used to push the drone 5 from the left and right directions.

The front surface of the slider 43 is elastically connected with a spring 44. The spring 44 is sleeved on the outer wall of the guide rail 45 and is concentric with the guide rail 45.

[0035] Referring to Figure 1 , there are two groups of first stoppers 310. The two groups of first stoppers 310 are symmetrically distributed on the left and right sides of the upper surface of the upper cover plate 2 with the upper cover plate 2 as the axis of symmetry. There are two groups of second stoppers 311. The two groups of second stoppers 311 are symmetrically distributed on the front and rear sides of the upper surface of the upper cover plate 2 with the upper cover plate 2 as the axis of symmetry. The two groups of first stoppers 310 and the two groups of second stoppers 311 can push the drone 5 on the surface of the upper cover plate 2 to the center of the upper cover plate 2 and clamp and fix the drone 5 respectively when approaching each other. The motor 31 is arranged on the lower surface of the box body 1.

[0036] Referring to Figure 1 、 Figure 2 , there are four groups of first long slots 35 and four groups of second long slots 36. The four groups of first long slots 35 and the four groups of second long slots 36 are axially distributed on the front and rear sides of the upper surface of the upper cover plate 2 with the upper cover plate 2 as the axis. The first long slots 35 and the second long slots 36 are used to allow the first round rod 39 and the second round rod 312 to penetrate to the upper surface of the upper cover plate 2 and slide on the inner wall of the slots. There are two groups of first round rods 39. The two groups of first round rods 39 are symmetrically distributed on the left and right sides of the box body 1 with the box body 1 as the axis of symmetry. Each group of first round rods 39 has two. The two first round rods 39 are symmetrically distributed on the front and rear sides of the lower surface of the first stopper 310. There are two groups of second round rods 312. The two groups of second round rods 312 are symmetrically distributed on the front and rear sides of the box body 1 with the box body 1 as the axis of symmetry. Each group of second round rods 312 has two. The two second round rods 312 are symmetrically distributed on the left and right sides of the lower surface of the second stopper 311.

[0037] Referring to Figure 2 、 Figure 3 , the first round rod 39 is slidably connected to the inner wall of the first long slot 35, the second round rod 312 is slidably connected to the inner wall of the second long slot 36, and the lower side of the outer wall of a group of second round rods 312 is slidably connected to the inner wall of the return rail 37.

[0038] Referring to Figure 5 , there are two groups of connecting rods 42. The two groups of connecting rods 42 are symmetrically distributed on the front and rear sides of the upper surface of the contact rod 41 with the contact rod 41 as the axis of symmetry. Pushing the contact rod 41 upward will cause the connecting rod 42 to be squeezed and move, thereby driving the two sliders 43 to move and approach each other.

[0039] Referring toFigure 5 One end of the spring 44 is fixedly connected to the front surface of a set of sliders 43, and the other end of the spring 44 is fixedly connected to the rear surface of another set of sliders 43. When the two sets of sliders 43 approach each other, the spring 44 will be compressed, and the spring 44 will generate a reaction force. The guide rail 45 is fixedly connected to the lower surface of the drone 5.

[0040] Working principle: When the device is in use, the whole device is placed on a flat outdoor ground to ensure that the surface of the device is horizontal. When the drone 5 needs to be charged, the operator operates the drone 5 to land it on the surface of the upper cover plate 2. When the landing position deviates from the center of the upper cover plate 2, the device cannot wirelessly charge the drone 5. At this time, the motor 31 is started to drive the gear 32 to rotate. The rotation of the gear 32 will drive the first rack 33 and the second rack 34 to move and approach each other. The first rack 33 drives the connecting block 38, the first round rod 39 and a set of first stoppers 310 to move, and the second rack 34 drives the first round rod 39 and another set of first stoppers 310 to move, so that the two sets of first stoppers 310 approach each other. At the same time, the first round rod 39 drives the two sets of return slide rails 37 to move. The return slide rails 37 squeeze the second round rod 312 to make the second round rod 312 move. The second round rod 312 drives the two sets of second stoppers 311 connected to it to move respectively, so that the two sets of second stoppers 311 approach each other. Thus, through the mutual cooperation of the two sets of first stoppers 310 and the two sets of second stoppers 311, the drone 5 can be pushed to gradually move to the center of the upper cover plate 2, and the first stoppers 310 and the second stoppers 311 will clamp the drone 5 to keep it stable. At this time, the motor 31 is turned off, and the wireless charger 6 is started to wirelessly charge the drone 5.

[0041] When the landing speed of the drone 5 is too fast, the contact rod 41 will first contact the surface of the upper cover plate 2. At this time, the downward impact force of the drone 5 will cause the drone 5 to drive the guide rail 45 to continue to move downward. The guide rail 45 will drive the slider 43 to move downward. The slider 43 drives the connecting rod 42 to rotate. At the same time, the connecting rod 42 will squeeze the slider 43 to make the two sets of sliders 43 approach each other. The slider 43 squeezes the spring 44, and the spring 44 is compressed to generate a reaction force, so that the impact force received by the drone 5 is reduced, thereby avoiding damage to the drone 5 due to excessive impact force.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
