Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) technology, and in particular relates to a UAV with a buffer support. Background Technology

[0002] Unmanned aerial vehicles (UAVs), abbreviated as URMs, are devices operated using radio remote control equipment and onboard program control devices, or autonomously operated completely or intermittently by an onboard computer. These include unmanned aerial vehicles, unmanned vehicles, and robotic dogs. With the rapid development of civilian drones, they are increasingly appearing in advertising, film and television, wedding video recording, and other applications. The drone's support frame provides support and cushioning during landing, effectively protecting the drone body. However, drone support frames are generally fixed. When the drone is equipped with a camera for aerial filming, especially when rotating for 360-degree shots, the support frame being within the camera's field of view can affect the filming quality. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a drone with a buffer support.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A drone with a buffer support includes a drone body equipped with a propeller, and a camera mounted on the bottom of the drone body; receiving grooves are opened on both sides of the bottom of the drone body, and one end of a sliding block is slidably arranged in the receiving groove; mounting blocks are symmetrically arranged at both ends of the bottom of the sliding block; a first support rod and a second support rod are respectively rotatably arranged on both sides of the mounting block.

[0006] A support block is provided between the first support rod and the second support rod. Connecting rods are rotatably provided on both sides of the support block. One of the connecting rods is rotatably connected to the side of the first support rod, and the other connecting rod is rotatably connected to the side of the second support rod.

[0007] The receiving groove is equipped with electric telescopic rods at both ends;

[0008] The top of the support block is provided with a sliding rod, which passes through the mounting block and the sliding block, extends into the receiving groove, and is connected to the output end of the electric telescopic rod.

[0009] With the above technical solution, after the drone takes off, the electric telescopic rod retracts, causing the sliding rod to slide upward, thereby moving the support block upward, which in turn moves the connecting rods on both sides upward. The first and second support rods connected to the connecting rods rotate to a vertical position as the support block and connecting rods move upward, causing the sliding block to slide into the receiving groove. At this time, the bottoms of the first and second support rods are higher than the camera, so they will not affect the camera range. When the drone lands, the electric telescopic rod extends, causing the sliding block to slide out of the receiving groove, and the first and second support rods are supported apart by the connecting rods and support rods. The bottoms of the first and second support rods are located below the camera, supporting the drone body when it lands and preventing the camera from touching the ground and being damaged.

[0010] Furthermore, the bottom of the two first support rods at both ends of the same sliding block is provided with a first support plate, and the first support rod and the first support plate are rotatably connected;

[0011] The bottom of the two second support rods at both ends of the same sliding block is provided with a second support plate, and the second support rod is rotatably connected to the second support plate.

[0012] Through the above technical solution, the first and second support plates increase the contact area with the ground, thus providing better support for the drone.

[0013] Furthermore, both ends of the first support plate are curved upwards;

[0014] The two ends of the second support plate are curved upwards.

[0015] Through the above technical solution, the first support plate and the second support plate can make better contact with the ground.

[0016] Furthermore, both the first support rod and the second support rod are damping telescopic rods;

[0017] The first support rod includes a first support member and a first telescopic member. The first support member is rotatably mounted on the mounting block. A first sliding groove is provided at the bottom of the first support member. One end of the first telescopic member is slidably disposed in the first sliding groove, and the other end is rotatably connected to the first support plate. A first spring is provided in the first sliding groove. One end of the first spring is connected to the first sliding groove, and the other end is connected to the first telescopic member.

[0018] Furthermore, the second support rod includes a second support member and a second telescopic member. The second support member is rotatably mounted on the mounting block. A second sliding groove is provided at the bottom of the second support member. One end of the second telescopic member is slidably disposed in the second sliding groove, and the other end is rotatably connected to the second support plate. A second spring is provided in the second sliding groove. One end of the second spring is connected to the second sliding groove, and the other end is connected to the second telescopic member.

[0019] Through the above technical solution, the first and second support rods play a good cushioning role when the drone lands.

[0020] Furthermore, the sliding block has limit grooves at both ends, and the sliding rod is provided with a limit block, which is slidably disposed in the limit groove.

[0021] Furthermore, the top and bottom of the limiting groove are provided with moving grooves, which penetrate the top of the sliding block and the bottom of the mounting block;

[0022] The slide bar is slidably positioned within the moving groove.

[0023] The above technical solution effectively limits the movement of the sliding block and the mounting block.

[0024] Furthermore, the second support rod is located on the side of the mounting block near the interior of the UAV body; and the bottom of the second support rod is slightly higher than the bottom of the first support rod.

[0025] The above technical solutions can gradually mitigate the impact of drones.

[0026] This utility model has the following beneficial effects:

[0027] 1. After the drone takes off, the electric telescopic rod retracts, causing the sliding rod to slide upward, which in turn moves the support block upward, and then moves the connecting rods on both sides upward. The first and second support rods connected to the connecting rods rotate to a vertical position as the support block and connecting rods move upward, causing the sliding block to slide into the receiving groove. At this time, the bottom of the first and second support rods is higher than the camera, which will not affect the camera range and better ensure the camera effect.

[0028] 2. When the drone lands, the electric telescopic rod extends, causing the sliding block to slide out of the receiving groove. The first and second support rods are then supported by the connecting rod and support rod. The bottoms of the first and second support rods are located below the camera, providing support for the drone body during landing and preventing the camera from touching the ground and being damaged.

[0029] 3. Both the first and second support rods are made of damping material, which has a good buffering effect and plays a good role in buffering the impact force between the aircraft and the ground when landing. Attached Figure Description

[0045] like Figure 1-5As shown, a drone with a buffer support includes a drone body 1 equipped with propellers, wherein the propellers are located on both sides of the drone body 1 and rotated by a drive device to control the takeoff of the drone. A camera 9 is mounted on the bottom of the drone body 1, and the camera 9 is detachably connected to the drone body 1 through a mounting mechanism, which is conventional technology and will not be described in detail here. Receiving grooves 11 are opened on both sides of the bottom of the drone body 1. One end of a sliding block 2 is slidably mounted in the receiving groove 11. Mounting blocks 21 are symmetrically arranged at both ends of the bottom of the sliding block 2. A first support rod 3 and a second support rod 4 are rotatably mounted on both sides of the mounting block 21, respectively. A support block 5 is provided between the first support rod 3 and the second support rod 4. Connecting rods 51 are rotatably mounted on both sides of the support block 5, one connecting rod 51 being rotatably connected to the side of the first support rod 3; the other connecting rod 51 is rotatably connected to the side of the second support rod 4. Electric telescopic rods 12 are provided at both ends of the receiving groove 11; the top of the support block 5... The unit is equipped with a sliding rod 52, which passes through the mounting block 21 and the sliding block 2, extends into the receiving groove 11, and is connected to the output end of the electric telescopic rod 12. After the drone takes off, the electric telescopic rod 12 retracts, causing the sliding rod 52 to slide upward, thereby causing the support block 5 to move upward, and then causing the connecting rods 51 on both sides to move upward. The first support rod 3 and the second support rod 4 connected to the connecting rod 51 rotate to a vertical state as the support block 5 and the connecting rod 51 move upward, causing the sliding block 2 to slide into the receiving groove 11. At this time, the bottom of the first support rod 3 and the second support rod 4 are higher than the camera 9, which will not affect the camera range. When the drone lands, the electric telescopic rod 12 extends, causing the sliding block to slide out of the receiving groove 11, and supports the first support rod 3 and the second support rod 4 through the connecting rod 51 and the support rod. The bottom of the first support rod 3 and the second support rod 4 are located below the camera 9, supporting the drone body 1 when it lands and preventing the camera 9 from touching the ground and being damaged.

[0046] Preferably, the bottom of the two first support rods 3 at both ends of the same sliding block 2 is provided with a first support plate 31, and the two first support rods 3 and the first support plate 31 are rotatably connected; the bottom of the two second support rods 4 at both ends of the same sliding block 2 is provided with a second support plate 41, and the two second support rods 4 and the second support plate 41 are rotatably connected. The two ends of the first support plate 31 are upward-curved arcs; the two ends of the second support plate 41 are upward-curved arcs. The first support plate 31 and the second support plate 41 increase the contact area with the ground, better supporting the drone, and the upward-curved arc sides can also make better contact with the ground. The second support rod 4 is located on the side of the mounting block 21 close to the inside of the drone body 1; and the bottom of the second support rod 4 is slightly higher than the bottom of the first support rod 3. The first support rod 3 first provides cushioning, and the second support rod 4 then provides cushioning, which can disperse the cushioning force and make the drone land better. After the drone lands, the first support rod 3 and the second support rod 4 are both supported on the ground by the weight of the drone itself.

[0047] Preferably, both the first support rod 3 and the second support rod 4 are damping telescopic rods. The first support rod 3 includes a first support member 32 and a first telescopic member 33. The first support member 32 is rotatably mounted on the mounting block 21. A first sliding groove 34 is provided at the bottom of the first support member 32. One end of the first telescopic member 33 is slidably disposed in the first sliding groove 34, and the other end is rotatably connected to the first support plate 31. A first spring 35 is provided in the first sliding groove 34. One end of the first spring 35 is connected to the first sliding groove 34, and the other end is connected to the first telescopic member 33. The second support rod 4 includes a second support member 42 and a second telescopic member 33. The retractable component 43 and the second support component 42 are rotatably mounted on the mounting block 21. The bottom of the second support component 42 is provided with a second sliding groove 44. One end of the second telescopic component 43 is slidably disposed in the second sliding groove 44, and the other end is rotatably connected to the second support plate 41. A second spring 45 is provided in the second sliding groove 44. One end of the second spring 45 is connected to the second sliding groove 44, and the other end is connected to the second telescopic component 43. The damping material has a good buffering effect. The elastic force of the first spring 35 and the second spring 45 causes the first support rod 3 and the second support rod 4 to slowly extend after retracting, thereby improving the shock absorption and buffering effect.

[0048] Preferably, the sliding block 2 has limit grooves 22 at both ends, and the sliding rod 52 has a limit block 53. The limit block 53 is slidably disposed in the limit groove 22. The top and bottom of the limit groove 22 are provided with moving grooves 23, which pass through the top of the sliding block 2 and the bottom of the mounting block 21. The sliding rod 52 is slidably disposed in the moving groove 23. When the electric telescopic rod 12 retracts, the sliding rod 52 drives the limit block 53 to slide from the bottom to the top in the limit groove 22, releasing the support state of the first support rod 3 and the second support rod 4. Under the limiting action of the limit groove 22, the sliding block 2 is driven to move upward and slide into the storage groove.

[0049] The working principle of this utility model is as follows: When the drone is not in operation, the first support rod 3 and the second support rod 4, under the action of the support block 5 and the connecting rod 51, form a triangle to support the drone. After the drone takes off, the electric telescopic rod 12 retracts, the sliding rod 52 slides upward in the moving groove 23, and the limiting block 53 slides in the limiting groove 22. When the support block 5 at the bottom of the sliding rod 52 moves upward, the connecting rods 51 on both sides move upward, releasing the supporting effect on the first support rod 3 and the second support rod 4, so that the first support rod 3 and the second support rod 4 rotate to a vertical position as the support block 5 and the connecting rod 51 move upward. When in the straight position, the limiting block 53 is located at the top of the limiting groove 22, which in turn drives the sliding block 2 to slide into the storage groove. At this time, the bottom of the first support rod 3 and the second support rod 4 are higher than the camera 9, which will not affect the camera range. When the drone lands, the electric telescopic rod 12 extends to make the sliding block slide out of the receiving groove 11, and supports the first support rod 3 and the second support rod 4 through the connecting rod 51 and the support rod. The bottom of the first support rod 3 and the second support rod 4 are located below the camera 9, which supports the drone body 1 when it lands and prevents the camera 9 from touching the ground and being damaged.

[0050] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
