DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides Figure 1-6 The buffer drone support device shown in the figure includes a first fixing frame 1, a second fixing frame 2, a fastening bolt 5, a bottom plate 8 and a leg 6. The first fixing frame 1 and the second fixing frame 2 are U-shaped plate structures. Two groups of slide grooves 3 are symmetrically opened on the inner side edges of the protruding sections at both ends of the first fixing frame 1. Slide bars 4 are fixed on the outer sides of the protruding sections at both ends of the second fixing frame 2. The slide grooves 3 are plugged with the slide bars 4. Fastening bolts 5 are installed on the outer sides of the two ends of the first fixing frame 1. The fastening bolts 5 can play a role in assisting the fastening of the slide bars 4. The fastening bolts One end of 5 is placed on the top of the slide bar 4, and a plurality of groups of mounting plates are equidistantly fixed on the outer sides of the first fixing frame 1 and the second fixing frame 2, and mounting holes are arranged on the mounting plates. The first fixing frame 1 and the second fixing frame 2 form a mounting frame, and legs 6 are hingedly mounted at the four corners of the bottom of the mounting frame, and a buffer structure 15 is hingedly mounted at the bottom of the leg 6. A bottom plate 8 is horizontally fixed at the four corners of the bottom of the mounting frame and close to the leg 6, and a supporting structure 9 is hingedly mounted at the bottom of the bottom plate 8, and an end of the supporting structure 9 away from the bottom plate 8 is hingedly mounted on the inner side of the leg 6.

[0023] Specifically, the buffer structure 15 includes a mounting seat 151, a hinge ring 16, a spreader rod 17 and a base plate 18. The mounting seat 151 is a U-shaped sheet structure. A hinge ring 16 is fixed at the top of the mounting seat 151. A rubber pad is attached to the outer edge of the hinge ring 16, which can have a certain friction with the hinge at the bottom of the leg 6, and can ensure that the buffer structure 15 will not shake during flight. The buffer structure 15 is buffered as a whole. The hinge ring 16 is hingedly installed at the bottom of the leg 6. The spreader rod 17 is symmetrically hingedly installed at the bottom of the mounting seat 151. A connecting structure 19 is provided in the middle section between the two groups of the spreader rods 17. A hinge plate 181 is fixed at the middle section of the top of the base plate 18, and the hinge plate 181 is hingedly installed at the bottom of the spreader rod 17.

[0024] Specifically, the connecting structure 19 includes a connecting tube 20, a slider 21, a buffer spring 22 and an extension rod 23. The connecting structure 19 can stretch the two groups of support rods 17, thereby performing preliminary buffering and shock absorption on the device during the falling process. A buffer cavity is opened inside the connecting tube 20, and two groups of sliders 21 slide symmetrically in the buffer cavity. Extension rods 23 are fixed on the outer sides of the two groups of sliders 21. The extension rod 23 extends out of the connecting tube 20, and a pull ring 24 is fixed on the extension end. The pull ring 24 is hingedly installed on the inner side of the expansion rod 17, and a buffer spring 22 is installed on the extension rod 23 on the outer side of the slider 21 in the buffer cavity.

[0025] Specifically, the support structure 9 includes a support tube 10, a slide 11 and an elastic buffer pad 14. The support structure 9 can perform secondary buffering and shock absorption on the device when the support leg 6 moves outward. The support tube 10 is provided with two groups. A matching cavity is opened inside the support tube 10. A slide 11 is slidably arranged in the matching cavity. A connecting rod 12 is fixed between the two groups of the slides 11. An elastic buffer pad 14 is installed on the connecting rod 12 between the two groups of the support tubes 10. A connecting rod 12 is provided at one end of the slide 11 in the matching cavity close to the elastic buffer pad 14.

[0026] Specifically, the elastic buffer pad 14 has a cylindrical structure. The elastic buffer pad 14 can provide auxiliary support between the two groups of support tubes 10 during the rebound process, thereby preventing the slide 11 from having a large elastic force during the rebound process. A through groove for the connecting rod 12 to pass through is opened in the center, and a spring is embedded in the elastic buffer pad 14.

[0027] Specifically, the clamping structure 25 includes an adjusting rod 26, a bevel gear 27 and a clamping block 29. The clamping structure 25 can fix the entire mounting frame well when needed, and can fix the mounting frame according to different unmanned homes. The adjusting rod 26 is horizontally inserted and installed in the clamping cavity. Two groups of L-shaped clamping blocks 29 are symmetrically installed in the clamping cavity and on the adjusting rod 26. A bevel gear 27 is installed in the middle section of the adjusting rod 26, and a 28 for driving the bevel gear 27 to rotate is provided at the bottom of the mounting frame.

[0028] Specifically, two groups of threads with opposite spiral directions are symmetrically provided at the corresponding engaging cavity of the adjusting rod 26, and the engaging blocks of the adjusting rod 26 are thread-matched.

[0029] Specifically, a matching wheel is fixed to the top of the rotating disk 28 through a connecting rod. The matching wheel is arranged between the two groups of clamping cavities, and the matching wheel is meshed with the bevel gear.

[0030] Working principle: before the buffer drone support device works, when the device needs to be installed, the turntable 28 is rotated. When the turntable 28 rotates, the matching wheel is driven to rotate, and the matching wheel and the bevel gear 27 are screw-engaged, so that the adjusting rod 26 is rotated, and the clamping block 29 is threadedly engaged with the adjusting rod 26, so that the clamping block 29 is well adjusted, and then the mounting frame is preliminarily fixed. After the preliminarily fixed, the mounting plate is fixed by bolts, and then fixed on the drone. At this time, the width of the mounting frame composed of the first fixing frame 1 and the second fixing frame 2 is adjusted, so that different sizes of mounting frames can be used. The installation requirements of the drone, after adjustment, the device is installed on the drone by bolts. When the device lands, the extension rod 17 first falls and opens, and the extension rod 23 opens and is pulled, and then the slider 21 is pulled, and then the buffer spring 22 is compressed, and then the impact of the fall is initially absorbed. After the buffer structure 15 absorbs part of the impact, the legs 6 move to both sides under the action of the impact of the fall, and then the support structure 9 is stretched as a whole. During the stretching process, the impact of the fall is buffered and damped for a second time through the internal connecting rod 12, thereby improving the overall buffering effect of the device. The buffer drone support device is reasonably designed, can provide good buffering and damping for the drone during operation, and can adjust the support device according to the size of the drone chassis when necessary, and is suitable for promotion and use.

Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
