Description

Technical Field

[0001] The utility model relates to the technical field of drone tripods, in particular to a folding drone tripod. Background Art

[0002] An unmanned aerial vehicle, abbreviated as "drone", is a pilotless aircraft controlled by a radio remote control device and a self-contained program control device. With the development of technology, drones are widely used in military, planting, forestry and other fields.

[0003] A drone generally includes a fuselage and a tripod installed under the fuselage, and the tripod is used to support the fuselage. However, the existing drone tripods generally cannot be folded, resulting in the drone occupying a large amount of space when carried, making it inconvenient to carry. In addition, since the support area of the existing tripod cannot be adjusted, when the drone lands, it is prone to roll over, with poor support performance and poor use effect. For this reason, we propose a folding drone tripod. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned drawbacks in the prior art, and to propose a folding drone tripod.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: design a folding drone tripod, including two parallel mounting plates fixed on both sides of the bottom of the drone. At both ends of the bottom of each mounting plate, fixing blocks are vertically installed. A connecting shaft is rotatably connected between each pair of fixing blocks. At both ends of the connecting shaft, connecting blocks are fixedly installed. At the bottom of each connecting block, a first support rod is installed. The bottom of each first support rod extends into the sliding sleeve, and the bottoms of the two sliding sleeves on the same side are connected by a cross bar;

[0006] Torsion springs are sleeved at both ends of the connecting shaft. One end of each torsion spring is fixed to the bottom of the mounting plate, and the other end of each torsion spring is fixed to the side of the corresponding connecting block;

[0007] At both ends of the bottom of each mounting plate, a rotating shaft is rotatably connected. At the bottom end of the rotating shaft, a limiting block is fixedly installed. When the first support rod rotates to the horizontal position, one end of the limiting block extends below the first support rod and has a clearance fit with the surface of the first support rod;

[0008] At both ends of each cross bar, a connecting sleeve is rotatably connected. On one side of each connecting sleeve, a second support rod is installed. At both ends of each cross bar, a limiting sleeve is also installed. Inside each limiting sleeve, a limiting rod is slidably connected. One end of each limiting rod extends to one side of the corresponding second support rod.

[0009] Preferably, a strip-shaped fixed plate is fixedly installed between two first support rods on the same side. A lead screw is rotatably connected to the bottom of the strip-shaped fixed plate. The bottom of the lead screw extends into the threaded sleeve, and the bottom of the threaded sleeve is fixed to the side of the cross bar.

[0010] Preferably, the second support rod is arranged in an "L" shape.

[0011] Preferably, an anti-disengagement block is installed at one end of each limiting rod. A spring is slidably sleeved on the side of each limiting rod. One end of the spring is fixed to the side of the anti-disengagement block, and the other end of the spring is fixed to the end of the limiting sleeve.

[0012] Preferably, support blocks are installed at both ends of each cross bar. The diameter of the support block is larger than the diameter of the connecting sleeve.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0027] Referring to Figures 1-6 , a folding tripod for a drone includes two parallel mounting plates 1 fixed to both sides of the bottom of the drone. At both ends of the bottom of each mounting plate 1, fixing blocks 2 are vertically installed. A connecting shaft 3 is rotatably connected between each pair of fixing blocks 2. At both ends of the connecting shaft 3, connection blocks 20 are fixedly installed. At the bottom of each connection block 20, a first support rod 5 is installed. During actual use, the first support rod 5 can rotate along the connecting shaft 3 following the connection block 20. Thus, when the drone is not in use, the first support rod 5 can be folded and stored.

[0028] As Figure 3 shown, torsion springs 21 are sleeved at both ends of the connecting shaft 3. One end of each torsion spring 21 is fixed to the bottom of the mounting plate 1, and the other end of each torsion spring 21 is fixed to the side surface of the corresponding connection block 20. Under the action of the torsion of the torsion spring 21, the first support rod 5 will be opened, so that when the drone is in use, the first support rod 5 can support the drone.

[0029] As Figure 1 shown, a strip-shaped baffle 4 is installed on one side of each pair of connection blocks 20, and one side of the connection block 20 abuts against the side surface of the corresponding strip-shaped baffle 4. Thus, under the action of the strip-shaped baffle 4, the connection block 20 is limited, preventing the first support rod 5 from rotating too much and affecting the support.

[0030] It should be noted that, as Figure 2 shown, the included angle between the strip-shaped baffle 4 and the mounting plate 1 is A, 95° ≤ A ≤ 260°. When the drone lands, it will be supported by the ground, which will cause the first support rod 5 to be pressed against the strip-shaped baffle 4. The first support rod 5 will not shake, making the landing of the drone more stable.

[0031] As Figure 1 shown, the bottom of each first support rod 5 extends into the inside of the sliding sleeve 14, and the bottoms of the two sliding sleeves 14 on the same side are connected by a cross bar 10. A strip-shaped fixing plate 13 is fixedly installed between the two first support rods 5 on the same side. The bottom of the strip-shaped fixing plate 13 is rotatably connected to a lead screw 12. The bottom of the lead screw 12 extends into the threaded sleeve 11, and the bottom of the threaded sleeve 11 is fixed on the side surface of the cross bar 10. During actual use, by rotating the lead screw 12, the cross bar 10 can be controlled to move under the action of the threaded sleeve 11, so that the sliding sleeve 14 on the cross bar 10 moves along the first support rod 5, so that the distance between the cross bar 10 and the mounting plate 1 can be adjusted. When folding, the cross bars 10 and the first support rods 5 on both sides will not collide.

[0032] As Figure 2 , Figure 3 and Figure 4 shown, the two ends of the bottom of each mounting plate 1 are rotatably connected to a rotating shaft 17. The bottom end of the rotating shaft 17 is fixedly installed with a limit block 18. When the first support rod 5 rotates to the horizontal position, one end of the limit block 18 extends below the first support rod 5 and has a clearance fit with the surface of the first support rod 5. After the first support rod 5 is folded, the first support rod 5 rotates to the horizontal position. Then, the staff rotates the rotating shaft 17, so that one end of the limit block 18 can rotate below the first support rod 5, and under the torque action of the torsion spring 21, the first support rod 5 will tightly abut against the side surface of the limit block 18 to fix the limit block 18, and the folding can be completed.

[0033] As Figure 1 shown, both ends of each cross bar 10 are rotatably connected to a connecting sleeve 19. A second support rod 6 is installed on one side of each connecting sleeve 19. During actual use, when the drone needs to be used, the staff can rotate the connecting sleeve 19 to rotate the second support rod 6 to the horizontal position. As Figure 2 shown, in this way, the support area of the tripod is increased by the second support rod 6, and the stability of the drone landing is improved.

[0034] As Figure 1 shown, limit sleeves 16 are also installed at both ends of each cross bar 10. A limit rod 8 is slidably connected inside each limit sleeve 16. One end of each limit rod 8 extends to one side of the corresponding second support rod 6. When not in use, the second support rod 6 can be rotated to a position flush with the sliding sleeve 14 and fixed by the limit rod 8. And as Figure 2 shown, when in use, when the second support rod 6 is rotated to the horizontal position, the limit rod 8 contacts the top of the second support rod 6 to continue to limit the second support rod 6, so that the second support rod 6 will not deflect during the process of supporting the drone.

[0035] It should be noted that, as Figure 6 shown, a number of anti-slip teeth 22 are installed on the inner surface of the connecting sleeve 19. The side surfaces of the anti-slip teeth 22 are in clearance fit with the side surfaces of the cross bar 10, which will increase the friction between the connecting sleeve 19 and the cross bar 10. During the flight of the UAV, the second support rod 6 will not deflect due to the inertia or vibration of the UAV flight.

[0036] It should be noted that the second support rod 6 is arranged in an "L" shape, which will increase the contact area between the second support rod 6 and the ground during use and improve the support effect of the second support rod 6.

[0037] Specifically, when the present utility model is in use, the staff first pulls the limit rod 8 so that one end of the limit rod 8 disengages from the second support rod 6, and then rotates the second support rod 6 to rotate the second support rod 6 to a preset position, and then releases the limit rod 8. The spring 9 contracts, driving the limit rod 8 to move, so that one end of the limit rod 8 abuts against the top of the second support rod 6 to fix the second support rod 6. By means of the second support rod 6, the support area of the tripod can be increased, and the support stability for the UAV can be improved. When the UAV is not in use, the staff can rotate the lead screw 12, and the lead screw 12 drives the threaded sleeve 11 to move, and then the cross bar 10 can be moved towards the mounting plate 1. When the cross bar 10 moves to the preset position, the staff rotates the first support rod 5 so that the first support rod 5 rotates along the connecting shaft 3, as Figure 5 shown, rotate the first support rod 5 under the UAV, and then rotate the rotating shaft 17 so that one end of the limit block 18 moves to the bottom of the first support rod 5 to fix the first support rod 5, and the folding can be completed.

[0038] Furthermore, as Figure 1 shown, an anti-disengagement block 15 is installed at one end of each limit rod 8, and a spring 9 is slidably sleeved on the side surface of each limit rod 8. One end of the spring 9 is fixed on the side surface of the anti-disengagement block 15, and the other end of the spring 9 is fixed at the end of the limit sleeve 16. Under the elastic force of the spring 9, the limit rod 8 will be driven to move towards the second support rod 6, so that the limit rod 8 will not be separated from the second support rod 6.

[0039] Furthermore, as Figure 1 shown, support blocks 7 are installed at both ends of each cross bar 10. The diameter of the support block 7 is larger than the diameter of the connecting sleeve 19. During the landing process of the UAV, the support block 7 will first contact the ground, which will protect the cross bar 10, and the support block 7 is made of buffer rubber, and can also buffer the UAV when the UAV lands.

[0040] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
