[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Example 2

[0029] Reference Figure 1-7 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0030] The adjustment assembly includes an adjustment rod 9 with threads on the outer ring surface, a limit plate 10 and a plurality of counterweight plates 11. The lower end of the adjustment rod 9 is fixed to the upper surface of the adjustment plate 5, and the upper end of the adjustment rod 9 extends to the top of the mounting tube 3. The limit plate 10 is installed on the upper end of the adjustment rod 9. The upper surface of the adjustment plate 5 is provided with a receiving groove and the counterweight plate 11 is installed in the receiving groove through threads. The setting of the adjustment assembly facilitates personnel to adjust the position of the limit plate 10 on the adjustment rod 9, thereby controlling the minimum gap between the adjustment plate 5 and the bottom of the pressure relief port, and then controlling the rebound time of the support rod 4. speed, thereby achieving a certain degree of damping effect; damping cylinders 12 are installed in the middle of both ends of the mounting shell 1, and damping sliders 13 are installed inside the damping cylinders 12. The settings of the damping cylinders 12 and the damping sliders 13 further provide corresponding damping effects on the body cover, so as to reduce the shaking of the drone during landing; the shell of the mounting shell 1 is a transparent shell, and the four corners of the shell of the mounting shell 1 are provided with through openings. Since the shell of the mounting shell 1 is a transparent shell, when the mounting shell 1 is used, personnel can conveniently observe the inside of the body cover, that is, the middle of the drone body 17.

[0031] A bottom buffer cotton 14 is installed on the inner bottom surface of the mounting shell 1, and a top buffer cotton 15 is provided on the lower surface of the top cover 2. The arrangement of the bottom buffer cotton 14 and the top buffer cotton 15 further reduces the vibration force transmitted to the drone through the body cover when the drone lands; a slide rail 16 is provided on the lower surface of the mounting shell 1, and the middle frame of the limit frame 8 is slidably connected to the slide rail 16. The arrangement of the slide rail 16 improves the stability of the limit frame 8 when in use; an anti-slip pattern is provided on the lower surface of the limit frame 8, and the body of the mounting tube 3 is transparent. Since the body of the mounting tube 3 is transparent, it is convenient for personnel to promptly know the wear condition between the support rod 4 and the mounting tube 3, so as to promptly maintain the support rod 4.

[0032] The utility model also provides a drone with a body cover, including a drone body 17 and a drone body cover according to the above-mentioned drone body, wherein the middle part of the drone body 17 is covered between the mounting shell 1 and the top cover 2 of the body cover, that is, the middle part of the drone body 17 is protected by the body cover.

[0033] Principle of use and advantages: During use, the utility model provides a protective effect for the drone body 17 through the proposed mounting shell 1 and the top cover 2, and before the drone takes off, the personnel presses each support rod 4 into the air cavity and drives the limit frame 8 to move through the electric cylinder 7, and finally the support rod 4 is limited and supported by the limit frame 8, that is, the support rod 4 is prevented from extending out during the flight of the drone and affecting the stability of the drone; when the drone lands, the end of the limit frame 8 is moved out from the lower end of the mounting tube 3 through the electric cylinder 7 before landing, and the top spring 6 is changed from a compressed state to a rebound state at this time, that is, the lower end of the support rod 4 moves to the bottom of the mounting tube 3, and the moving speed of the support rod 4 is limited by the size of the gap between the lower surface of the adjustment plate 5 and the pressure relief port.

[0034] Furthermore, when the drone lands, the lower end of the support rod 4 contacts the ground first. At this time, the support rod 4 contracts toward the inside of the mounting tube 3 due to the gravity of the drone, that is, the support rod 4 compresses the top spring 6, thereby achieving the effect of shock absorption for the landing of the drone through the deformation of the top spring 6, and in the process of the support rod 4 contracting toward the inside of the mounting tube 3, the air inside the mounting tube 3 is squeezed by the support rod 4 and discharged along the pressure relief port, but because the pressure relief port is blocked by the adjusting plate 5, the air can only be discharged slowly, that is, the air inside the mounting tube 3 is gradually compressed, thereby having a buffering effect on the support rod 4, and when the support rod 4 rebounds under the action of the top spring 6, the air pressure inside the mounting tube 3 shows a gradual negative pressure trend, thereby having a damping effect on the top spring 6.

[0035] In summary, when the body cover proposed in this scheme is in use, it has a double buffering and shock-absorbing effect through the cooperation of the top spring 6, the support rod 4 and the mounting tube 3, and can have a certain degree of damping effect, so as to further reduce the shaking amplitude of the body cover after landing. That is, the drone proposed in this scheme has less vibration when landing through the body cover in this scheme, and the subsequent shaking amplitude is reduced, and the electric cylinder 7 only needs to be started for a short time when the drone lands. Therefore, compared with the traditional solution in which the drive motor needs to run all the time, this solution will not cause too much interference to the drone's endurance when used.

[0036] It should be further explained that the setting of the adjustment component makes it easy for personnel to adjust the position of the limit plate 10 on the adjustment rod 9, thereby controlling the minimum gap between the adjustment plate 5 and the bottom of the pressure relief port, and then controlling the speed of the support rod 4 when it rebounds, thereby achieving a certain degree of damping effect; the setting of the damping cylinder 12 and the damping slider 13 further provides a corresponding damping effect on the body cover, so as to reduce the shaking of the drone during landing; since the shell of the mounting shell 1 is a transparent shell, when the mounting shell 1 is used, personnel can easily observe the inside of the body cover, that is, the middle part of the drone body 17; the setting of the bottom buffer cotton 14 and the top buffer cotton 15 further reduces the vibration force transmitted to the drone through the body cover when the drone lands; the setting of the slide rail 16 improves the stability of the limit frame 8 when it is used; since the body of the mounting cylinder 3 is transparent, it is convenient for personnel to promptly know the wear between the support rod 4 and the mounting cylinder 3, so as to promptly maintain the support rod 4.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
