Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a buffer tripod for unmanned aerial vehicles. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft that are controlled by radio remote control equipment and self-contained program control devices. UAVs are actually a general term for unmanned aerial vehicles. From a technical point of view, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc. Compared with manned aircraft, they have the advantages of small size, low cost, easy use, low requirements for combat environment, and strong battlefield survivability. During the take-off and landing of UAVs, in order to prevent the UAV from experiencing large impact forces that cause damage to the fuselage and load, a buffer tripod will be installed on the UAV. At present, most of the common buffer tripods on the market are directly fixed on the side or bottom of the UAV. Its structure is U-shaped and made of plastic. Its buffering mainly relies on the elasticity of plastic parts to absorb some vibration and impact, but its buffering effect is poor and its protection ability for the UAV is poor. In addition, this type of buffering bracket is generally fixed directly on the side or bottom of the UAV by screws, which will increase the size of the UAV and make it inconvenient to carry the UAV.

[0003] In view of the problems existing in the prior art, the utility model discloses a UAV buffer tripod, which adopts a technical solution comprising a UAV body, two fixing plates are fixedly installed on the two side surfaces of the middle part of the UAV body, a flip positioning mechanism is installed on the two fixing plates on the same side, and a buffer mechanism is installed on the flip positioning mechanism;

[0004] The flip positioning mechanism comprises a screw rod, a positioning block, a positioning groove and a rotating rod, the end faces at both ends of the rotating rod are respectively rotatably connected to the opposite side faces of the two fixed plates, a positioning groove is provided in the middle of one of the end faces of the rotating rod, the outer side of the positioning groove is circular, and the inner side is square, one end of the screw rod passes through a screw hole on the side face of one of the fixed plates and is rotatably connected to the middle part of the side face of the positioning block, the positioning block is square, the positioning block is located in the positioning groove, and the positioning block matches the square part in the positioning groove;

[0005] The buffer mechanism includes a guide rod, a moving block, a support plate, a spring, a positioning plate, a mounting plate and a buffer plate, the mounting plate is fixedly mounted on the side of the rotating rod, the side surfaces at both ends of the mounting plate are respectively rotatably connected to the side surfaces of one end of the two support plates, the buffer plate is U-shaped, the opposite side surfaces at both ends of the buffer plate are fixedly connected to the two ends of the guide rod, the two ends of the guide rod respectively pass through the sliding holes on the sides of the two moving blocks, the side surfaces of the two moving blocks are respectively rotatably connected to the side surfaces of the other ends of the two support plates, the two support plates are distributed in an eight-shaped shape, the side surface of the middle part of the buffer plate is fixedly mounted with a positioning plate, the outer sides of the two ends of the guide rod are sleeved with springs, and the two ends of the two springs are respectively fixedly connected to the side surfaces of the two moving blocks and the two side surfaces of the positioning plate.

[0006] As a preferred technical solution of the utility model, a rubber pad is fixedly installed on the bottom of the buffer plate.

[0007] As a preferred technical solution of the present utility model, the other end of the screw rod is fixedly connected to the middle part of the end surface of the knob.

[0011] The beneficial effects of the utility model are as follows: the support plate of the utility model rotates to both sides when the buffer plate is impacted, and the moving block stretches the spring so that the elasticity of the spring absorbs the impact. Compared with the traditional integrated buffer tripod, the deformation ability is stronger and the impact resistance is also stronger, so that the buffer tripod can better provide protection for the drone. The positioning block can be driven to move by the screw rod. When the positioning block moves to the circular part in the positioning groove, the rotating rod can be rotated so that the entire buffer mechanism can be flipped from the bottom of the drone to the side of the drone body, thereby reducing the overall volume of the drone and facilitating the carrying of the drone. The rubber pad can provide protection for the buffer plate to prevent the buffer plate from being damaged under impact. The knob can be used to conveniently twist the screw rod to rotate the buffer mechanism. The anti-slip pattern can increase the friction force on the side of the knob, which is convenient for people to twist the knob. The guide rod can guide the positioning block to prevent the positioning block from rotating and affecting the positioning of the rotating rod. The large-pitch screw rod can enable people to quickly drive the positioning block to move, shorten the time for adjusting the position of the positioning block, and facilitate use.

DETAILED DESCRIPTION

[0016] Example 1

[0017] like Figures 1 to 3 As shown, the utility model discloses a UAV buffer tripod, which adopts a technical solution that includes a UAV body 1, two fixing plates 2 are fixedly installed on the two side surfaces of the middle part of the UAV body 1, a flip positioning mechanism 3 is installed on the two fixing plates 2 on the same side, and a buffer mechanism 4 is installed on the flip positioning mechanism 3;

[0018] The flipping positioning mechanism 3 includes a screw rod 31, a positioning block 32, a positioning groove 33 and a rotating rod 34. The end faces at both ends of the rotating rod 34 are rotatably connected to the opposite sides of the two fixed plates 2 respectively. A positioning groove 33 is provided in the middle of one of the end faces of the rotating rod 34. The outer side of the positioning groove 33 is circular and the inner side is square. One end of the screw rod 31 passes through a screw hole on the side of one of the fixed plates 2 and is rotatably connected to the middle part of the side of the positioning block 32. The other end of the screw rod 31 is fixedly connected to the middle part of the end face of the knob 6. The screw rod 31 is a large-pitch screw rod. The large-pitch screw rod 31 can enable people to quickly drive the positioning block 32 to move, shorten the time for adjusting the position of the positioning block 32, and facilitate use. The side of the knob 6 is provided with anti-slip grooves 7. Through the knob 6, people can conveniently twist the screw rod 31 to rotate to flip the buffer mechanism 4. The anti-slip pattern 7 can increase the friction force on the side of the knob 6, making it easier for people to twist the knob 6. The positioning block 32 is square and is located in the positioning groove 33. The positioning block 32 matches the square part in the positioning groove 33. Two guide rods 8 are fixedly installed on the side of one of the fixing plates 2. One end of the two guide rods 8 is slidably installed in the two sliding holes on the side of the positioning block 32. The positioning block 32 can be guided by the guide rod 8 to prevent the positioning block 32 from rotating and affecting the positioning of the rotating rod 34. The positioning block 32 can be driven to move by the screw 31. When the positioning block 32 moves to the circular part in the positioning groove 33, the rotating rod 34 can rotate, so that the entire buffer mechanism can be flipped from the bottom of the drone to the side of the drone body 1, thereby reducing the overall volume of the drone and facilitating the carrying of the drone.

[0019] The buffer mechanism 4 includes a guide rod 41, a moving block 42, a support plate 43, a spring 44, a positioning plate 45, a mounting plate 46 and a buffer plate 47. The mounting plate 46 is fixedly mounted on the side of the rotating rod 34. The sides at both ends of the mounting plate 46 are rotatably connected to the sides of one end of the two support plates 43. The buffer plate 47 is U-shaped. The opposite sides at both ends of the buffer plate 47 are fixedly connected to the two ends of the guide rod 41. The two ends of the guide rod 41 pass through the sliding holes on the sides of the two moving blocks 42 respectively. The sides of the two moving blocks 42 are rotatably connected to the sides of the other ends of the two support plates 43 respectively. The two support plates 43 are distributed in an eight-shaped shape. The side of the middle part of the buffer plate 47 is fixedly mounted with a fixed The bottom of the positioning plate 45 and the buffer plate 47 are fixedly installed with a rubber pad 5, and the rubber pad 5 can provide protection for the buffer plate 47 to prevent the buffer plate 47 from being damaged under impact. The outer sides of both ends of the guide rod 41 are sleeved with springs 44, and the two ends of the two springs 44 are respectively fixedly connected to the side surfaces of the two moving blocks 42 and the two side surfaces of the positioning plate 45. When the buffer plate 47 is impacted, it can be rotated to both sides through the support plate 43, and the moving block 42 can stretch the spring 44, so that the elasticity of the spring 44 absorbs the impact. Compared with the traditional integrated buffer tripod, the deformation ability is stronger and the impact resistance is also stronger, so that the buffer tripod can better provide protection for the drone.

[0020] The working principle of the utility model is as follows: when the drone body 1 lands, the buffer plate 47 at the bottom will first contact the ground. The impact force of the drone body 1 falling will cause the two support plates 43 to rotate to both sides. One end of the two support plates 43 will drive the two moving blocks 42 to move, so that the two moving blocks 42 move to both sides along the direction of the guide rod 41, so that the two moving blocks 42 stretch the two springs 44, so that the elasticity of the two springs 44 absorbs the impact force of the drone body 1 falling, thereby playing a buffering role for the drone body 1 and avoiding damage to the drone body 1. When carrying the drone body, the knob 6 can be twisted to make the knob 6 drive the screw rod 31 to rotate, and the screw rod 31 drives the positioning block 32 to move along the screw hole on the fixing plate 2, and the positioning block 32 moves along the guide rod 8 to the circular part of the positioning groove 33, and the buffer plate 47 is pushed to make the buffer plate 47 drive the rotating rod 34 to rotate, so that the buffer plate 47 and the support plate 43 are flipped to the side of the drone body 1, and the knob 6 is twisted in the opposite direction to make the knob 6 drive the screw rod 31 to rotate, so that the screw 31 drives the positioning block 42 to move to the square part in the positioning groove 33, and the rotating rod 34 is positioned.
