[0014] A further technical solution of the utility model is that a plurality of guardrails are connected to the bottom of the body, and the vertical distance from the bottom of the plurality of guardrails to the bottom of the body is greater than the vertical distance from the bottom of the camera to the bottom of the body.

[0015] The beneficial effect is that the guardrail is arranged so that the guardrail contacts the ground during the landing of the drone, thereby reducing the damage caused by direct contact between the camera and the ground.

[0016] A further technical solution of the utility model is that the guardrail is rotatably mounted on the bottom of the machine body.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] The embodiment of the present application discloses a tilt photography fixing device.

[0032] Reference Figure 1 and Figure 2 A device for fixing oblique photography of unmanned aerial vehicles comprises a body 1. In this embodiment, four connecting rods 2 are fixedly installed along the circumference of the body 1. Blades 3 are rotatably installed at the ends of the four connecting rods 2 away from the body 1, and the unmanned aerial vehicle is lifted off by rotating the blades 3; a camera 4 is installed at the bottom of the body 1. When the unmanned aerial vehicle is lifted off by rotating the blades 3, the camera 4 installed at the bottom of the body 1 takes pictures, so that the photographer can obtain pictures that cannot be obtained by shooting on the ground; a cavity 5 is opened inside the body 1, and a rotating component 6 is installed inside the cavity 5. The rotating component 6 is connected to the camera 4. The rotating component 6 is used to drive the camera 4 to rotate, so that when the photographer needs to shoot pictures at different angles, the position of the unmanned aerial vehicle can be adjusted without adjusting the position of the unmanned aerial vehicle. The bottom of the rotating component 6 is connected to a height adjustment component 7, and the height adjustment component 7 is connected to the camera 4. When vertical photography cannot meet the shooting requirements, the tilt state of the camera 4 is adjusted by the height adjustment component 7, so that the camera 4 can shoot more real and intuitive pictures.

[0033] Reference Figure 1 and Figure 2The rotating assembly 6 includes a rotating shaft 61 and a driving motor 62. The rotating shaft 60 is rotatably mounted on the inner top wall of the cavity 5. The end of the rotating shaft 61 away from the top wall of the cavity 5 is connected to the camera 4, and the rotation of the camera 4 is realized by the rotation of the rotating shaft 61; the driving motor 62 is fixedly mounted on the inner top wall of the cavity 5, and the output end of the driving motor 6 is connected to the rotating shaft 61 through a gear set 8. The driving motor 62 and the rotating shaft 61 are installed in parallel. The gear set 8 includes a driving gear 81 fixedly mounted on the output end of the driving motor 62 and a driven gear 82 fixedly mounted on the outer surface of the rotating shaft 61. The driving gear 81 and the driven gear 82 are meshed with each other to drive the rotating shaft 61 to rotate. The driving motor 62 enables the rotating shaft to rotate automatically. The driving gear 81 and the driven gear 82 are meshed with each other to transmit the rotation of the camera 4 more stably.

[0034] Reference Figure 1 and Figure 2 The body 1 is provided with a mounting hole 12, which is connected to the cavity 5. The size of the mounting hole 12 matches the size of the rotating shaft 61. The rotating shaft 61 is rotatably installed in the mounting hole 12. The setting of the mounting hole 12 enables the rotating shaft 61 to achieve 360-degree rotation, so that the camera 4 can perform 360-degree photography; an end cover 13 is fixedly connected to the end of the rotating shaft 61 away from the camera 4. The size of the end cover 13 is larger than the size of the mounting hole 12. The rotating shaft 61 is installed from the mounting hole 12 toward the cavity 5, and the end cover 13 abuts against the end of the mounting hole 12 away from the cavity 5. The setting of the end cover 13 reduces the probability of the rotating shaft 61 falling off from the mounting hole 12.

[0035] Reference Figure 1 and Figure 2 , the end of the rotating shaft 61 away from the end cover 13 is connected to the height adjustment component 7, and the height adjustment component 7 includes a horizontally arranged mounting plate 71 and a plurality of telescopic rods 72 evenly installed along the length direction of the mounting plate 71. In this embodiment, two groups of telescopic rods 72 are provided, which are respectively installed at the two ends of the length direction of the mounting plate 71. The telescopic rod 72 is fixedly installed at the end of the mounting plate 71 away from the rotating shaft 61, and the movable end of the telescopic rod 72 is connected to the top of the camera 4; when it is necessary to tilt the camera 4 to shoot a more concrete picture, the camera 4 can shoot the object at different tilt angles by adjusting the length of the movable end of the telescopic rod 72; the telescopic rod 72 uses an electric telescopic rod 72, and the setting of the electric telescopic rod 72 makes the adjustment of the movable end of the telescopic rod 72 automatic, thereby improving the adjustment efficiency; because the telescopic rod 72 is always in a vertical state, the movable end of the telescopic rod 72 is rotatably connected to the top of the camera 4. In this embodiment, the telescopic rod 72 is hinged to the top of the camera 4 so that the hinge will not affect the height adjustment of the telescopic rod when the height of the camera 4 is adjusted.

[0036] Reference Figure 1 and Figure 2A protective plate 9 is fixedly installed on the body 1 at the bottom of the cavity 5 in the circumferential direction. The bottom of the mounting plate 71 abuts against the protective plate 9 facing the cavity 5. The protective plate 9 provides load-bearing for the camera 4 to reduce the gravity exerted on the rotating shaft 61, thereby improving the stability of the camera 4 during rotation.

[0037] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , a plurality of guardrails 10 are installed at the bottom of the body 1. In this embodiment, two groups of guardrails 10 are provided. The guardrails 10 are formed of a trapezoidal shape by a tube body. The two groups of guardrails 10 are installed on both sides of the width direction of the camera 4. A certain angle is formed between the guardrails 10 and the bottom plate. The vertical distance from the bottom of the guardrail 10 to the bottom of the body 1 is greater than the vertical distance from the bottom of the camera 4 to the bottom of the body 1. When the drone completes shooting and lands, the guardrail 10 abuts against the ground to prevent the camera 4 from directly contacting the ground, thereby reducing the probability of the camera 4 being damaged by contact with the ground; two groups of lifting rods 11 are fixedly installed at the bottom of the body 1. The lifting rods 11 are vertically installed on the body 1. The movable ends of the two groups of lifting rods 11 are respectively connected to the guardrails 10. A rotating ring 14 is fixedly installed at the bottom of the body 1. The top of the guardrail 10 rotates The protective fence 10 is movably installed in the rotating ring 14; when the drone is launched for shooting, in order to reduce the influence of the protective fence 10 on the rotation of the camera 4, the lifting rod 11 is started to make the bottom of the protective fence 10 move toward the body 1, and the end of the protective fence 10 rotates in the rotating ring 14; when the drone is finished shooting, the lifting rod 11 is started to make the protective fence 10 move away from the body 1 until the vertical distance from the bottom of the protective fence 10 to the bottom of the body 1 is greater than the vertical distance from the bottom of the camera 4 to the bottom of the body 1; the lifting rod 11 uses an electric lifting rod 11 to improve the stability of the position of the protective fence 10, and the movable end of the lifting rod 11 is rotatably connected to the protective fence 10. In this embodiment, a hinge is used. When the protective fence 10 rotates, the movable end of the lifting rod 11 is hinged with the protective fence 10 and will not limit the rotation of the protective fence 10.

[0038] The implementation principle of this embodiment is as follows: when the drone is used for photography, the blades 3 rotate to drive the body 1 to rise into the air. When the preset height is reached, the lifting rod 11 is started to move the guardrail 10 toward the bottom of the body 1, and the camera 4 is started for photography. When it is necessary to shoot the object at multiple angles, the drive motor 62 is started to drive the shaft 61 to rotate, and the rotation of the shaft 61 causes the camera 4 to rotate. When the camera 4 rotates to the shooting angle, the drive motor 62 is turned off to use the camera 4 for photography. When vertical photography cannot meet the shooting requirements, the telescopic rod 72 is started to make the camera 4 tilted as a whole for photography. When the shooting is completed, the lifting rod 11 is started to move the guardrail 10 away from the bottom of the body 1. When the drone lands, the bottom of the guardrail 10 contacts the ground. The drone is then stored for next use.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
