Description

Technical Field

[0001] This utility model relates to the field of camera pan-tilt units, specifically a camera pan-tilt unit that facilitates automatic focusing. Background Technology

[0002] A camera pan-tilt head is a general term for a type of camera mount. Some of these mounts have the function of adjusting the camera's shooting direction by changing the camera's position. Changing the target being shot by an optical camera may cause the captured image to become blurry, requiring refocusing. This involves changing the distance between the lenses in the internal lens group to adjust the focal length and obtain a suitable image.

[0003] Cameras typically have a focusing ring near the lens. By rotating the focusing ring, the internal structure of the camera can be adjusted to achieve focus. However, cameras mounted on a gimbal are not always easy for users to focus in all usage scenarios, and not all cameras have built-in autofocus functions. Therefore, a camera gimbal that facilitates autofocus is needed. Utility Model Content

[0004] I. Technical problems to be solved

[0005] The technical problem this invention aims to solve is that a camera mounted on a gimbal may need to be refocused when capturing images.

[0006] II. Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a camera gimbal that facilitates automatic focusing, including a camera instrument, a focusing ring connected to the front end of the camera instrument near the lens, and a base connected below the camera instrument for mounting the camera instrument and for adjusting the shooting direction of the camera instrument.

[0008] The camera is equipped with a dial ring that triggers the rotation of the focusing ring on the outer side of its front end, and a power mechanism that drives the dial ring to rotate is installed below the camera.

[0009] The dial ring is internally connected to a clamping assembly that clamps and carries the adjusting ring to rotate together with the dial ring.

[0010] Furthermore, the clamping assembly includes a clamping rod arranged in a Z-shape within the dial ring.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1

[0024] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a camera gimbal that facilitates automatic focusing, which directly connects to the attached... Figure 1 It is known that it includes a camera device 2, a focusing ring 3 is connected to the front end of the camera device 2 near the lens, and a base 1 is connected below the camera device 2 for mounting the camera device 2 and for adjusting the shooting direction of the camera device 2;

[0025] The base 1 and the so-called camera gimbal, the camera instrument 2 as the main part of the camera, according to the existing technology, the gimbal is the mounting base for supporting the camera, and the gimbal will be equipped with some modules for camera adjustment, which will not be described in detail here;

[0026] Combined with appendix Figure 1 Appendix Figure 3 and their thumbnails Figure 5-6 The camera instrument 2 has a dial ring 7 that triggers the rotation of the focusing ring 3 on its outer front side. The dial ring 7 is connected to a clamping assembly that clamps and carries the adjusting ring to rotate together with the dial ring 7. The clamping assembly includes a clamping rod 9 arranged in a Z-shape inside the dial ring 7. The clamping rod 9 is connected to a screw hole 10 and a sliding hole 13 at its upper and lower parts, respectively. The dial ring 7 has a bidirectional screw 11 that passes through the screw hole 10 and is threaded to the clamping rod 9. The screw 11 has handles 12 connected to both ends. The dial ring 7 has a support shaft 14 that provides load-bearing for the clamping rod 9 connected to its bottom. The clamping rod 9 is slidably connected to the dial ring 7 by sliding through the sliding hole 13 and sleeved on the outside of the support shaft 14.

[0027] This gimbal device aims to use a dial ring 7 to replace the manual rotation of the focus ring 3 on the camera, thereby achieving camera focusing and meeting higher quality shooting requirements. First, a clamping assembly is designed to install the dial ring 7 on the focus ring 3, ensuring that the focus ring 3 and the dial ring 7 rotate together. Two clamping rods 9 are movable within the dial ring 7. They are moved away from or close to each other within the dial ring 7 or outside the focus ring 3 by the rotation of the screw 11 and the limiting of the lower support shaft 14. When the two clamping rods 9 clamp the focus ring 3, they not only satisfy the concentric positioning and clamping of the dial ring 7 and the focus ring 3, but also become a whole, achieving joint rotation. To enhance this synchronization effect and protect the focus ring 3 during clamping, a rubber pad can be installed on the inside of the clamping rods 9.

[0028] Example 2

[0029] Combined with appendix Figure 1-3 and appendix Figure 4-5The camera instrument 2 is equipped with a power mechanism that can drive the dial ring 7 to rotate. The power mechanism includes a transmission shaft 5, which is rotatably connected to the camera instrument below. The camera instrument 2 is equipped with a motor 4 that drives and cooperates with the transmission shaft 5 at the bottom. The end of the transmission shaft 5 is connected to a gear 6. The dial ring 7 is evenly connected inward with a plurality of guide teeth 8 that mesh with the gear 6.

[0030] By clamping the focusing ring 3 and rotating the dial ring 7 which is integrated with it, the focal length of the camera can be changed. The motor 4, which is installed below the camera instrument 2, is always synchronized with the camera instrument 2 on the gimbal. After the motor 4 runs, the drive shaft 5 will rotate. A gear 6 is connected to the end of the drive shaft 5. On the same surface as the gear 6, many guide teeth 8 are evenly arranged inside the dial ring 7 to form a toothed ring. The toothed ring meshes with the gear 6. After the drive shaft 5 rotates, the dial ring 7, which is the carrier of the toothed ring, will also rotate to a corresponding degree, thereby driving the focusing ring 3 to rotate as well.

[0031] In a specific implementation of this invention, the camera 2 is mounted on the base 1 to form a camera device. The base 1 acts as a gimbal, adjusting the camera's shooting position during daily use. When the camera is adjusted, the shooting target may change, resulting in blurriness, requiring refocusing. At this time, the motor 4 starts running, causing the transmission shaft 5 to rotate to a certain extent. The gear 6 drives the dial ring 7, which contains a toothed disc structure, to rotate together. The dial ring 7 is pre-mounted on the focusing ring 3 via a clamping assembly, becoming an integral part of it. Thus, the focusing ring 3 is driven by external force to rotate, achieving the effect of adjusting the focal length. Once the camera successfully focuses, normal high-quality shooting can be achieved.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
