Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 8 As shown, this embodiment provides a UAV landing aid device based on visual recognition, including a body 1 and further comprising:

[0030] Support legs 2, symmetrically arranged at the bottom of the body 1;

[0031] The connecting plates 3 are respectively arranged under the two supporting legs 2. The interiors of the two supporting legs 2 are provided with guide grooves for the movement of the connecting plates 3. The bottoms of the two connecting plates 3 are provided with buffer plates 4.

[0032] The mounting assembly is symmetrically arranged on the outside of the supporting foot 2;

[0033] The buffer assembly is symmetrically arranged on the upper surface of the buffer plate 4;

[0034] The reinforcement assembly is symmetrically arranged on the upper surface of the buffer plate 4.

[0035] The above working principle: when the body 1 needs to be buffered and protected, it is only necessary to first insert the connecting plate 3 into the guide groove inside the supporting foot 2, and then fix the connecting plate 3 and the supporting foot 2 through the installation component. At this time, the buffer component and the reinforcement component can be fixed and installed. When the body 1 lands, the buffer plate 4 will directly collide with the ground. At this time, the buffer plate 4 will drive the buffer component to move synchronously. During the movement of the buffer component, it can effectively buffer the impact force, thereby effectively buffering the supporting foot 2 and the body 1. During the movement of the buffer plate 4, it will also drive the reinforcement component to start moving synchronously. At this time, the reinforcement component can further enhance the buffering effect of the body 1 and the supporting foot 2, thereby further buffering and protecting the body 1 and the supporting foot 2, effectively extending the service life of the body 1 and the supporting foot 2, saving time and effort.

[0036] In order to effectively fix the connecting plate 3 and the supporting foot 2, the mounting assembly includes a mounting block 6 symmetrically arranged on the outside of the supporting foot 2, the interior of the mounting block 6 is fixedly connected with a slide rod 8, the outside of the slide rod 8 is slidably connected with a contact plate 9, the outside of the slide rod 8 is sleeved with a return spring 10, the return spring 10 is in contact between the contact plate 9 and the mounting block 6, the outside of the contact plate 9 is symmetrically provided with a connecting rod 11, the other end of each two connecting rods 11 is fixedly connected with a pull plate, the upper surface of the contact plate 9 is fixedly connected with a moving plate 12, the upper surface of the mounting block 6 is provided with a guide groove for the moving plate 12 to move, the opposite side of the two moving plates 12 is fixedly connected with an insertion rod 13, the interior of the connecting plate 3 is provided with a guide groove for the insertion rod 13 to move, when it is necessary to fix the connecting plate 3 to the supporting foot 2 When the lever 13 is pulled back, the return spring 10 is reset, driving the contact plate 9 to move synchronously, and the contact plate 9 and the movable plate 12 are driven to move synchronously. When the movable plate 12 is released, the movable plate 12 and the insertion rod 13 are driven to move synchronously. When the insertion rod 13 is inserted into the guide groove inside the connecting plate 3, the connecting plate 3 and the supporting foot 2 can be fixed. At this time, the buffer assembly and the reinforcement assembly can be fixed and installed.

[0037] Taking into account that the body 1 needs to be buffered and protected when it lands, the buffer assembly includes a fixed plate 14 symmetrically arranged on the upper surface of the buffer plate 4, the interior of the fixed plate 14 is fixedly connected to a buffer rod 15, the outside of the buffer rod 15 is slidably connected to a slider 16, the upper surface of the fixed plate 14 is provided with a guide groove for the slider 16 to move, the outside of the buffer rod 15 is sleeved with a first buffer spring 17, the first buffer spring 17 is in contact between the slider 16 and the fixed plate 14, the upper surfaces of the two sliders 16 are hinged to a hinge block 19 through a hinge rod 18, the upper surface of the hinge block 19 is fixedly connected to a top plate 20, the upper surface of the top plate 20 is fixedly connected to the bottom of the connecting plate 3, the upper surface of the buffer plate 4 is fixedly connected to a first damping rod 21, the telescopic end of the first damping rod 21 is connected to the hinge block 19 The bottom of the frame 1 is fixedly connected. When the machine body 1 lands, the buffer plate 4 will directly collide with the ground. At this time, the buffer plate 4 will be displaced. Since the two sliders 16 and the hinge block 19 are hinged by the hinge rod 18, the slider 16 will also move synchronously on the outside of the buffer rod 15 during the movement of the buffer plate 4. During the movement of the slider 16, the first buffer spring 17 will be squeezed. At this time, the vibration force can be buffered by the first buffer spring 17, so that the support foot 2 and the machine body 1 can be effectively buffered and protected. Through the setting of the first damping rod 21, the elastic potential energy of the first buffer spring 17 can be effectively limited, thereby avoiding the repeated rebound of the first buffer spring 17, affecting the buffering effect of the first buffer spring 17.

During the movement of the buffer plate 4, the support plate 22 will also be driven to move synchronously. , the support plate 22 then drives the movable wheel 24 to move synchronously outside the trapezoidal block 27. When the movable wheel 24 moves outside the trapezoidal block 27, the second damping rod 23 and the second buffer spring 25 will be squeezed synchronously. At this time, the second buffer spring 25 can be used to further enhance the buffering effect, thereby further providing buffering protection for the machine body 1 and the support foot 2, effectively extending the service life of the machine body 1 and the support foot 2. Through the setting of the second damping rod 23, the elastic potential energy of the second buffer spring 25 can be effectively limited, thereby avoiding the repeated rebound of the second buffer spring 25, affecting the buffering effect of the second buffer spring 25. Through the setting of the telescopic rod 28, the stability of the buffer plate 4 during movement can be effectively improved.
