AI Technical Summary
Existing dual-gimbal drones are prone to gimbal collisions or obstruction of the lens when moving the camera at large angles, and there is a risk of collision when flying at high speeds, making it impossible to meet the needs of monitoring and shooting in multiple directions at the same time.
A dual-gimbal drone was designed, comprising an adaptation device, an auxiliary device, and a protective device. The gimbal position is automatically adjusted through components such as a fixed rod, an adjusting rod, and a hinge plate. With the help of springs and a limiting mechanism, it avoids obstructing the line of sight and shifting the center of gravity, and repels birds and animals during high-speed flight, ensuring the stability and safety of the gimbal and camera.
This effectively avoids obstructing the view and shifting the center of gravity when the gimbal is adjusted, increases the monitoring range, reduces the risk of gimbal collisions and bird/animal strikes, and ensures stable flight and shooting results for the drone.

DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0018] Please refer to Figures 1-7 An embodiment of the present application is a double holder unmanned aerial vehicle, comprising a fuselage 1, a wing 2 is fixed to the side wall of the fuselage 1, a power cabin 3 is fixed to the end of the wing 2 away from the fuselage 1, a motor is fixed inside the power cabin 3, a rotating shaft is fixed to the output end of the motor, a propeller blade 4 is fixed to the outer wall of the rotating shaft, an adaptive device for automatically moving the position of the double holder is fixed below the fuselage 1.
[0019] The adaptive device comprises a fixed rod 51, an adjusting rod 52, a fixed plate 53, a round rod 54, a hinged plate 55, a sliding plate 56, a hanging rod 57, a first holder 58, a hinged rod 59 and a counterweight 510. The fixed rod 51 penetrates through the protrusion at the bottom of the machine body 1 and is fixedly connected at the penetration position. The fixed rod 51 penetrates through the adjusting rod 52 and is rotatably connected at the penetration position. The fixed plate 53 is fixedly connected to one end of the adjusting rod 52 away from the fixed rod 51. When the control device is turned on, the adjusting rod 52 rotates. When the adjusting rod 52 rotates, the fixed plate 53 also rotates around the central axis of the fixed rod 51. When the adjusting rod 52 rotates from horizontal to vertical, the fixed plate 53 changes from the vertical state of abutting against the machine body 1 to the horizontal state. The round rod 54 is fixedly connected to the side wall of the fixed plate 53. When the fixed plate 53 rotates, the round rod 54 also rotates. The round rod 54 penetrates through one end of the hinged plate 55 and is rotatably connected at the penetration position. When the round rod 54 rotates around the central axis of the fixed rod 51, the hinged plate 55 also rotates. The sliding plate 56 is slidingly connected to the bottom surface of the machine body 1. The other end of the hinged plate 55 is hinged to the side wall of the sliding plate 56. The hinged plate 55 rotates to push the sliding plate 56 to slide away from the fixed rod 51. The hanging rod 57 is fixedly connected to the bottom surface of the sliding plate 56. The sliding plate 56 slides to move the hanging rod 57. The first holder 58 is fixedly connected to one end of the hanging rod 57 away from the sliding plate 56. The hanging rod 57 moves to move the first holder 58. One end of the hinged rod 59 is hinged to the bottom surface of the machine body 1. The counterweight 510 is slidingly connected to the inner wall of the adjusting rod 52. The other end of the hinged rod 59 is hinged to the side wall of the counterweight 510. When the adjusting rod 52 rotates, the hinged rod 59 also rotates. When the hinged rod 59 rotates, the counterweight 510 slides away from the fixed plate 53. When the unmanned aerial vehicle sails and the holder is opened for adjustment, the fixed rod 51, the adjusting rod 52, the fixed plate 53, the round rod 54, the hinged plate 55, the sliding plate 56 and the hanging rod 57 push the first holder 58 to move forward of the device, so that the first holder 58 and the monitoring camera loaded therein adjust the monitoring range, thereby avoiding that the monitoring range of the monitoring camera is blocked by the unfolded part, affecting the monitoring effect of the unmanned aerial vehicle, solving the problem that the unfolded part of the holder may block the monitoring line of sight of the monitoring camera when the holder of the device is adjusted. When the holder is unfolded, the center of gravity of the part borne by the machine body 1 is adjusted in cooperation with the hinged rod 59 and the counterweight 510, thereby avoiding that the center of gravity moves downward after the holder is unfolded, causing the overall stress of the device to change or be uneven, causing the device to be unable to continue normal sailing, solving the problem that the center of gravity moves downward after the holder is unfolded, which may affect the normal sailing of the device.
[0020] When the device takes off, the monitoring camera and the shooting camera are placed on the camera placing blocks of the two holders respectively, and then the device is controlled to take off. After the device takes off, the holder is adjusted manually by remote control to adjust the shooting range.
[0021] When the control device is opened, the adjusting rod 52 rotates, and the adjusting rod 52 rotates the fixed plate 53 around the central axis of the fixed rod 51. When the adjusting rod 52 rotates from horizontal to vertical, the fixed plate 53 changes from the vertical state of the body 1 to the horizontal state, and the fixed plate 53 rotates the round rod 54. The round rod 54 penetrates one end of the hinged plate 55, so that the round rod 54 rotates around the central axis of the fixed rod 51, and the hinged plate 55 also rotates at the penetration of the round rod 54. Because the length of the hinged plate 55 is much longer than the length of the adjusting rod 52, the end of the hinged plate 55 away from the round rod 54 is hinged to the side wall of the sliding plate 56, and the sliding plate 56 is slidingly connected to the bottom surface of the body 1. Therefore, the sliding plate 56 can only move in the horizontal direction, and the hinged point of the sliding plate 56 and the hinged plate 55 can also only move in the horizontal direction. When the end of the hinged plate 55 away from the sliding plate 56 rotates, the hinged plate 55 also rotates, and the hinged plate 55 rotates to push the sliding plate 56 to slide away from the fixed rod 51. The sliding of the sliding plate 56 drives the movement of the boom 57, and the movement of the boom 57 drives the movement of the first holder 58. When the adjusting rod 52 rotates, it also drives the counterweight 510 to rotate around the central axis of the fixed rod 51. The rotation of the counterweight 510 drives the rotation of the hinged point of the counterweight 510 and the hinged rod 59. The end of the hinged rod 59 away from the counterweight 510 is hinged to the bottom surface of the body 1, and the position does not change in the vertical direction and the horizontal direction. Therefore, when the hinged point of the counterweight 510 and the hinged rod 59 rotates, the hinged rod 59 also rotates, and the hinged rod 59 rotates to pull the counterweight 510 to slide away from the fixed plate 53.
[0022] Please refer to Figures 1-7On the basis of the above-mentioned embodiment, in another embodiment of the present application, the lower part of the fuselage 1 is provided with an auxiliary device for automatically adjusting the monitoring range, which comprises an L-shaped plate 61, a monitoring camera placing block 62, a sliding block 63, an adjusting spring 64 and a top rod 65. The L-shaped plate 61 is hinged to the upper surface of the first holder 58. When the adjusting holder is opened, the first holder 58 moves and drives the L-shaped plate 61 to move away from the adjusting rod 52. The monitoring camera placing block 62 is rotationally connected to the inner wall of the L-shaped plate 61. The L-shaped plate 61 drives the monitoring camera placing block 62 to move forward of the fuselage 1. The side wall of the sliding plate 56 is fixed with a protrusion. The sliding block 63 is slidingly connected to the bottom surface of the sliding plate 56 and the protrusion of the side wall thereof. One end of the adjusting spring 64 is fixedly connected to the upper surface of the monitoring camera placing block 62. When the monitoring camera placing block 62 rotates, it gradually moves away from the sliding plate 56, so that the adjusting spring 64 is stretched when the monitoring camera placing block 62 rotates. When the monitoring camera placing block 62 rotates, it also moves in the horizontal direction relative to the sliding plate 56, so that the adjusting spring 64 is also pulled to move when the monitoring camera placing block 62 rotates. The other end of the adjusting spring 64 is fixedly connected to the bottom surface of the sliding block 63. The adjusting spring 64 drives the sliding block 63 to slide. The top rod 65 is fixedly connected to the side wall of the hinged plate 55. When the hinged plate 55 rotates, it also drives the top rod 65 to rotate. When the top rod 65 rotates to the position of the L-shaped plate 61, the top rod 65 pushes the L-shaped plate 61 to rotate about the hinge between the L-shaped plate 61 and the first holder 58. The L-shaped plate 61 drives the monitoring camera placing block 62 to also rotate about the hinge between the L-shaped plate 61 and the first holder 58. When the auxiliary device is self-adaptively adjusted, the adjusting spring 64 buffers and limits the L-shaped plate 61 and the monitoring camera placing block 62, so that the L-shaped plate 61 and the monitoring camera placing block 62 are not limited when they move and are not rotated due to the movement, so that the monitoring camera does not fall from the monitoring camera placing block 62 when it repeatedly rotates. The problem that the L-shaped plate 61 and the monitoring camera placing block 62 are easily repeatedly rotated and the monitoring camera is shaken off is solved.
