Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to an angle adjustment bracket for UAV mapping cameras. Background Technology

[0002] A drone camera is a special camera device that can shoot from the air. It connects to the operator via wireless signals and transmits the high-altitude view to the display screen in real time. This type of camera is usually mounted on a stable bracket, so that the image can remain stable even when the flight is shaky. Its core feature is that it breaks through the geographical limitations of traditional cameras, allowing users to easily obtain the perspective that previously required a helicopter to shoot.

[0003] Common drone camera angle adjustment brackets are stepless, making it difficult to quickly adjust to the standard angle when facing tasks requiring shooting from a special angle. Furthermore, violent shaking during flight may cause the camera angle to change, resulting in cumbersome preparation work and camera instability during shooting. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an angle adjustment bracket for drone mapping cameras. It aims to improve upon the common drone camera angle adjustment brackets, which are stepless and difficult to quickly adjust to the standard angle when facing tasks that require shooting at special angles. Furthermore, violent shaking during flight may cause the camera angle to change, resulting in cumbersome preparation work and camera instability during shooting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle adjustment bracket for a drone mapping camera, comprising a body, a first rotating shaft rotatably connected to the lower part of the body via a bearing, a first ratchet fixedly connected to the outer wall of the first rotating shaft, an installation cylinder provided inside the first ratchet, a camera mechanism fixedly connected to the bottom of the installation cylinder, a first spring box slidably connected to the inner wall of the body via a first spring, a first locking tooth slidably connected to the inner wall of the first spring box via a second spring, the first locking tooth engaging with the tooth end of the first ratchet, and a first pressing block fixedly connected to the bottom of the first spring box.

[0006] The above solution utilizes a bearing to mount a first rotating shaft, a first ratchet to mount the first rotating shaft, a camera mechanism to mount the bottom of the ratchet, a first spring and a first spring box to mount inside the fuselage, a second spring to mount the first spring box, a first locking tooth to lock the first ratchet, and the first spring and a first pressing block to control the position of the first spring box. This allows for graded adjustment of the camera's shooting angle, improving upon the common stepless adjustment of drone camera angle adjustment brackets. This addresses the difficulty in quickly adjusting to a standard angle when facing tasks requiring special angle shooting, and the potential for camera angle changes due to violent shaking during flight, which leads to complex preparation work and camera instability during shooting.

[0007] Preferably, the camera mechanism includes a mounting bracket, and the camera is rotatably connected to the outer wall of the mounting bracket via a second pivot.

[0008] Preferably, a second ratchet is fixedly connected to the outer wall of the second rotating shaft on the side away from the camera, a second spring box is fixedly connected to the outer wall of the mounting bracket, and a second locking tooth is slidably connected to the inner wall of the second spring box through a fifth spring. The second locking tooth is engaged with the tooth end of the second ratchet.

[0009] Preferably, a turntable is fixedly connected to the outer wall of the second ratchet on the side away from the camera.

[0010] Preferably, the first ratchet has a spring groove inside, and the inner wall of the first ratchet is slidably connected to a locking pin by a third spring, wherein the third spring and the locking pin are located inside the spring groove.

[0011] Preferably, the inner wall of the first rotating shaft is slidably connected to a second pressing block via a fourth spring.

[0012] Preferably, the outer wall of the mounting cylinder has a pressing port.

[0013] Preferably, a rotor frame is fixedly connected to the upper part of the fuselage, and a rotor shaft is rotatably connected to the end of the rotor frame away from the fuselage. A rotor is fixedly connected to the outer wall of the rotor shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, a first rotating shaft is installed using a bearing, a first ratchet is installed using the first rotating shaft, a camera mechanism is installed at the bottom of the ratchet, a first spring and a first spring box are installed inside the body, a second spring is installed using the first spring box, a first locking tooth is used to lock the first ratchet, and the position of the first spring box is controlled by the first spring and the first pressing block. This allows for step-by-step adjustment of the camera's shooting angle, improving upon the common stepless adjustment brackets for drone camera angles. These brackets are difficult to quickly adjust to a standard angle when facing tasks requiring shooting at a special angle, and violent shaking during flight may cause the camera angle to change, resulting in complex preparation work and camera instability during shooting.

[0016] 2. In this utility model, by installing a third spring and a locking pin inside the first ratchet, the first rotating shaft is fixed by the locking pin, and the retraction of the locking pin is controlled by a fourth spring and a second pressing block, so that the camera mechanism can be quickly disassembled and assembled. This improves the problem that the camera installation process before drone shooting is complicated, often requires tools, and is difficult to implement in harsh outdoor environments, resulting in cumbersome drone camera installation work and the inability to shoot immediately in the face of emergencies.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-5 An embodiment of this utility model provides a UAV mapping camera angle adjustment bracket, including a body 1. The lower part of the body 1 is rotatably connected to a first rotating shaft 11 via a bearing 10. A first ratchet 12 is fixedly connected to the outer wall of the first rotating shaft 11. An installation cylinder 18 is provided inside the first ratchet 12. A camera mechanism is fixedly connected to the bottom of the installation cylinder 18. A first spring box 6 is slidably connected to the inner wall of the body 1 via a first spring 5. A first locking tooth 8 is slidably connected to the inner wall of the first spring box 6 via a second spring 7. The first locking tooth 8 is engaged with the tooth end of the first ratchet 12. A first pressing block 9 is fixedly connected to the bottom of the first spring box 6.

[0027] Specifically, the fuselage 1 is used to install the bearing 10 and the first spring 5. The bearing 10 is used to install and limit the first rotating shaft 11. The first rotating shaft 11 is used to install the first ratchet 12. By rotating the first ratchet 12, the mounting cylinder 18 and the camera mechanism fixed to the first ratchet 12 can rotate. The angle of the first ratchet 12 can be fixed by the first spring box 6 in conjunction with the second spring 7 and the first locking tooth 8. Taking the direction from the bearing 10 to the mounting cylinder 18 as the positive side, when the first ratchet 12 rotates clockwise, the tooth end of the first ratchet 12 pushes the first locking tooth 8 back into the first spring box 6. The second spring 7 can reset the first locking tooth 8. When the first ratchet 12 rotates counterclockwise, it will be locked by the first locking tooth 8 and cannot rotate. The gap between the first locking tooth 8 and the tooth end of the first ratchet 12 fits, thereby preventing the first ratchet 12 from shaking during flight. The first spring 5 in conjunction with the first pressing block 9 can control the movement and reset of the first spring box 6. When adjusting the angle counterclockwise, pressing the first pressing block 9 lifts the first spring box 6, causing the first locking tooth 8 and the tooth end of the first ratchet 12 to separate, thereby allowing the first ratchet 12 to rotate. The first rotating shaft 11 is installed using the bearing 10, and the first ratchet 12 is installed using the first rotating shaft 11. The camera mechanism is installed at the bottom of the first ratchet 12, and the first spring 5 and the first spring box 6 are installed inside the body 1. The second spring 7 is installed using the first spring box 6, and the first locking tooth 8 is used to lock the first ratchet 12. The position of the first spring box 6 is controlled by the first spring 5 and the first pressing block 9. This allows for step-by-step adjustment of the horizontal shooting angle of the camera 27, improving upon the common problem that the angle adjustment bracket of the drone camera 27 is stepless, making it difficult to quickly adjust to the standard angle when facing tasks requiring shooting at a special angle. Furthermore, violent shaking during flight may cause the camera 27 angle to change, resulting in complicated preparation work and instability of the camera 27 during shooting.

[0028] Reference Figure 6 The camera mechanism includes a mounting bracket 20, and a camera 27 is rotatably connected to the outer wall of the mounting bracket 20 via a second pivot 26.

[0029] Specifically, the mounting bracket 20 is used to mount the second rotating shaft 26, and the camera 27 is mounted through the second rotating shaft 26, thereby enabling the camera 27 to complete the shooting work.

[0030] Reference Figure 6 A second ratchet 25 is fixedly connected to the outer wall of the second rotating shaft 26 on the side away from the camera 27. A second spring box 21 is fixedly connected to the outer wall of the mounting bracket 20. A second locking tooth 23 is slidably connected to the inner wall of the second spring box 21 through a fifth spring 22. The second locking tooth 23 is engaged with the tooth end of the second ratchet 25.

[0031] Specifically, the second ratchet 25 controls the rotation of the second rotating shaft 26. The second spring box 21 is used to install the fifth spring 22 and the second locking tooth 23 is installed through the fifth spring 22. The fifth spring 22 can reset the second locking tooth 23, thereby cyclically locking the tooth end of the second ratchet 25. The angle of the second ratchet 25 is controlled by the second spring box 21 in conjunction with the fifth spring 22 and the second locking tooth 23. Taking the first pressing block 9 to the mounting cylinder 18 as the positive side, when the second ratchet 25 near the first pressing block 9 rotates clockwise, the tooth end of the second ratchet 25 pushes up the second locking tooth 23. When it rotates counterclockwise, the tooth end of the second ratchet 25 is locked by the second locking tooth 23. This allows for the graded adjustment of the vertical angle of the camera 27.

[0032] Reference Figure 6 The second ratchet 25 is fixedly connected to the outer wall of the side away from the camera 27 by a turntable 24.

[0033] Specifically, the turntable 24 is used to control the rotation of the second ratchet 25. The surface of the turntable 24 is provided with protrusions, which can increase the friction, making the rotation easier and the angle adjustment of the camera 27 more convenient.

[0034] Reference Figure 4 The first ratchet 12 has a spring groove 13 inside, and the inner wall of the first ratchet 12 is slidably connected to a locking pin 15 by a third spring 14. The third spring 14 and the locking pin 15 are located inside the spring groove 13.

[0035] Specifically, the spring groove 13 provides a channel for the movement of the third spring 14 and the locking pin 15. The locking pin 15 can be engaged into the hole of the mounting cylinder 18, thereby fixing the mounting cylinder 18 and the camera mechanism, thus enabling quick installation.

[0036] Reference Figure 5 The inner wall of the first rotating shaft 11 is slidably connected to the second pressing block 16 via the fourth spring 17.

[0037] Specifically, the fourth spring 17 is used to install and reset the second pressing block 16. The top surface of the second pressing block 16 is designed with rounded corners, which makes it easy to push the end of the locking pin 15 back into the first ratchet 12 from the inside of the first rotating shaft 11, thereby enabling the mounting cylinder 18 to be removed and improving the ease of disassembling the camera mechanism.

[0038] Reference Figure 2 The outer wall of the mounting cylinder 18 is provided with a pressing port 19.

[0039] Specifically, the pressing port 19 is for the user's hand to pass through, thereby pressing the second pressing block 16; by installing a third spring 14 and a locking pin 15 inside the first ratchet 12, the first rotating shaft 11 is fixed by the locking pin 15, and the retraction of the locking pin 15 is controlled by the fourth spring 17 and the second pressing block 16, so that the camera mechanism can be quickly assembled and disassembled, thereby improving the problem that the installation process of the camera 27 before drone shooting is complicated, often requires tools, and is difficult to implement in harsh outdoor environments, resulting in cumbersome installation of the drone camera 27 and the inability to shoot immediately in the face of emergencies.

[0040] Reference Figure 1 A rotor frame 2 is fixedly connected to the upper part of the fuselage 1. A rotor shaft 3 is rotatably connected to the end of the rotor frame 2 away from the fuselage 1. A rotor 4 is fixedly connected to the outer wall of the rotor shaft 3.

[0041] Specifically, the rotor mount 2 is used to mount the rotor shaft 3 and the rotor 4 is mounted on the rotor shaft 3. The rotor shaft 3 is connected to the electronic control system inside the fuselage 1 through the rotor mount 2, thereby controlling the rotation of the rotor shaft 3, which in turn drives the rotor 4 to rotate so that the UAV can fly.

[0042] Working principle: During use, when rotating clockwise with the bearing 10 to the mounting cylinder 18 as the positive side, the tooth end of the first ratchet 12 pushes the first locking tooth 8 back into the first spring box 6. Subsequently, the first locking tooth 8 is reset by the second spring 7, locking the tooth end of the first ratchet 12. This allows for step-by-step adjustment of the angle of the mounting cylinder 18 and the camera mechanism below it. When rotating counterclockwise, pressing the first pressing block 9 causes the first spring box 6 to rise, allowing the first ratchet 12 to rotate counterclockwise. After releasing, the first spring 5 pushes the first spring box 6 and resets it. When adjusting the vertical angle of the camera 27, the rotation... The turntable 24 drives the camera 27 to rotate via the second ratchet 25 and the second shaft 26. The vertical angle of the camera 27 can be adjusted in stages by using the second spring box 21, the fifth spring 22, and the second locking tooth 23 in conjunction with the second ratchet 25. During installation, the mounting cylinder 18 is aligned with the groove at the bottom of the first ratchet 12, and the end of the locking pin 15 is pushed back into the first ratchet 12 by pressing the second pressing block 16 through the pressing port 19. The mounting cylinder 18 is then inserted and the second pressing block 16 is released. The mounting cylinder 18 is then rotated to make the locking pin 15 engage in the hole, thus completing the installation of the mounting cylinder 18 and the camera mechanism.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
