[0024] In order to enable the personnel in the technical field to better understand the technical solutions in this application, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.

[0025] Embodiment 1:

[0026] As Figures 1-3 shown, a drone lifting platform can provide support for the take - off and landing of the drone. The adopted structure includes a support platform 3, a support frame 5 and adjustable legs. A buffer pad 1 is installed on the top of the support platform 3; the support frame 5 is placed at the bottom of the support platform 3 and is connected to the support platform 3 through a plurality of buffer mechanisms 6; at least three adjustable legs are installed at the bottom of the support frame 5.

[0027] The buffer pad 1 is installed on the top surface of the support platform 3, so that the buffer contact is made between the drone and the support platform 3 to avoid hard contact.

[0028] The buffer pad can be made of soft rubber. Soft rubber has softness.

[0029] As Figure 1 shown, the installation quantity of the buffer mechanism 6 can be 3, 4, 5 or 6, etc. A plurality of buffer mechanisms 6 are used to connect the support platform 3 and the support frame 5, which is used to support the drone to buffer and land on the buffer pad of the support platform. Prevent the drone from landing directly and hard, and can protect the drone from damage.

[0030] The adjustable legs can be extended and contracted. When the ground is uneven, it can be adjusted through the adjustable legs to make the top surface of the support platform 3 in a horizontal state.

[0031] Working mode:

[0032] Drone takeoff: Adjust through adjustable legs so that the top surface of the cushion is horizontal. Then place the drone on the cushion 1 to avoid placing the drone directly on the ground, and then the drone can be controlled to take off.

[0033] Drone landing: Control the vertical alignment with the cushion 1, and then control the drone to slowly land on the cushion 1. The cushion 1 plays a buffering role for the drone to avoid the drone directly landing on the support platform. At the same time, the drone pushes the cushion 1 and the support platform 3 downward, and the support platform 3 then pushes the buffer mechanism 6 downward, and the buffer mechanism realizes the buffering function, enabling the drone to achieve a buffered landing.

[0034] In some embodiments, in order to facilitate obtaining the horizontal information of the support frame, a spirit level 4 is added. As Figure 1 shown, the support frame 5 is installed with a plurality of spirit levels 4. The number of spirit levels installed can be 3 or 4. By checking the spirit level, it is convenient to adjust the support frame to a horizontal state through the adjustable legs.

[0035] In some embodiments, a detachable connection structure between the cushion and the support platform is given, and a fastener 2 is additionally installed. The cushion 1 and the support platform 3 are fixedly connected through the fastener 2.

[0036] The cushion 1 and the support platform 3 can be connected by a plurality of fasteners. The number of fasteners can be 2, 3, 4, 5, 6, etc. An appropriate number of fasteners can be selected according to needs.

[0037] In some embodiments, a structure of the fastener is given. As Figure 2 shown, the fastener 2 includes a limit head 21, a screw 22 and a nut 23. One end of the screw 22 is connected to the limit head 21, and the other end is threadedly connected to the nut 23.

[0038] In some embodiments, a connection structure of the fastener is given. The cushion is provided with a counterbore 101, and a first through hole 102 is opened at the bottom of the counterbore 101; a second through hole 31 corresponding to the first through hole 102 is opened on the support platform 3; the screw 22 passes through the counterbore 101, the first through hole 102, the second through hole 31 and is threadedly connected to the nut 23, and the limit head 21 sinks into the counterbore 101, and the top surface of the limit head 21 is aligned with the top surface of the cushion 1.

[0039] The limit head 21 sinks into the counterbore to prevent the limit head from protruding from the surface of the cushion.

[0040] The cushion and the support platform are fixedly connected: tighten the nut 23, and the limit head 21 and the nut 23 clamp and fixedly connect the cushion 1 and the support platform 3.

[0041] Disassembly of the buffer pad and the support platform: Unscrew the nut 23, and pull out the screw rod 22 from the second through hole 31, the first through hole 102 and the counterbore 101, then the buffer pad and the support platform can be disassembled. It can be understood that this facilitates the replacement of the buffer pad.

[0042] In some embodiments, in order to quickly install the buffer pad on the support platform, a limiting boss 12 is added for installation. As Figure 1 、 2 shown, the buffer pad 1 is provided with a limiting boss 12, and a positioning hole 32 corresponding to the limiting boss 12 is provided on the support platform 3. During installation, insert the limiting boss 12 into the positioning hole 32, and the buffer pad can be quickly installed on the support platform.

[0043] In some embodiments, a structure of the adjustable leg is given. As Figure 1 、 3 shown, the adjustable leg includes a chassis 7, an adjusting nut 8, an adjusting screw rod 9 and a receiving cylinder 11. The adjusting nut 8 is fixedly installed on the chassis 7, one end of the adjusting screw rod 9 is fixedly connected to the adjusting nut 8, and the other end is threadedly connected to the receiving cylinder 11.

[0044] Adjusting method of the adjusting screw rod 9:

[0045] Rotate the adjusting screw rod 9 clockwise, the adjusting screw rod 9 screws into the receiving cylinder 11, the adjusting screw rod contracts inside the receiving cylinder, so that the length of the adjusting screw rod extending out of the receiving cylinder becomes shorter, realizing the lowering of the height.

[0046] Rotate the adjusting screw rod 9 counterclockwise, the adjusting screw rod 9 screws out of the receiving cylinder 11, the adjusting screw rod extends out of the receiving cylinder, so that the length of the adjusting screw rod extending out of the receiving cylinder becomes longer, realizing the raising of the height.

[0047] The chassis 7 serves as a support.

[0048] In some embodiments, a fixing structure of the chassis is given, and fixing nails 10 are additionally installed. A plurality of chassis holes 71 are circumferentially distributed on the chassis 7, and the fixing nails 10 pass through the chassis holes 71 to fix the chassis 7 to the ground.

[0049] As Figure 1 、 3 shown, the number of the chassis holes 71 can be 1, 2, 3 or 4, etc. An appropriate number of chassis holes can be selected according to needs.

[0050] The fixing nails fix the chassis to the ground, which can make the adjustable leg stably support the support frame, and the support frame stably supports the support platform and the buffer pad.

[0051] In some embodiments, a structure of a buffer mechanism is provided. The buffer mechanism 6 includes a damper 64, a sleeve 61, and a spring 63. The damper 64 is provided with a damper rod 641. The sleeve 61 is vertically spaced from the damper 64. And the damper rod 641 is inserted into one end of the sleeve 61 and extends to be connected to the other end of the sleeve 62. The spring 63 sleeved on the sleeve 61 and the damper 64, and one end thereof is fixedly connected to the sleeve 61 and the other end is connected to the support frame 5.

[0052] The sleeve 61 is installed on the support platform 3. When the drone lands on the buffer pad, it will push the buffer pad and the support platform downward. While the support platform pushes the sleeve downward, the sleeve squeezes the spring to generate elastic deformation, and squeezes the damper rod to contract into the damper. The damper and the spring jointly buffer the descent of the sleeve, thereby realizing the buffered descent of the buffer pad and the support platform, and further realizing the buffered landing of the drone, preventing the drone from hard landing and avoiding damage to the drone during landing.

[0053] It should be noted that the sleeve 61 sleeved on the damper when moving downward.

[0054] The combination of the damper and the spring can achieve a better buffering effect. The damper can slow down the elastic deformation of the spring and also slow down the elastic reset of the spring. When the drone lands on the buffer pad, the buffer pad exerts a first buffering effect on the drone. The combination of the damper and the spring exerts a second buffering effect, that is, the drone pushes down the buffer pad and the support platform, the damper rod contracts into the damper, and the spring is compressed downward to generate elastic deformation, realizing the buffering and shock absorption of the drone landing. It can be understood that the damper pulls the spring to prevent the spring from instantaneously elastically resetting upward when the drone landing is completed. Under the action of the damper, the spring gradually elastically resets upward to avoid the drone falling off the support platform due to too fast elastic reset.

[0055] In some embodiments, a connection structure between the spring and the sleeve is provided, and a limiting ring 62 is additionally installed. The limiting ring 62 is installed on the sleeve 61 and is used for connecting with the spring 63.

[0056] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
