Description

Technical Field

[0001] This invention relates to the field of photographic and video equipment technology, and more particularly to a gimbal camera. Background Technology

[0002] In photography and videography equipment, a camera used for everyday shooting is a standalone device that requires the user to hold the camera by hand to capture the scene.

[0003] When shooting images with specific requirements, the camera's shooting angle needs to be adjusted accordingly. In this case, on the one hand, the user needs to operate manually, which reduces the shooting experience (especially when taking selfies in distant views); on the other hand, the camera's temperature will rise due to prolonged operation, which can easily reduce the image quality.

[0004] Therefore, there is an urgent need to provide a gimbal camera to solve the above problems. Summary of the Invention

[0036] In this embodiment, the gimbal camera includes a lens barrel 1, a top cover 4, a bottom cover 6, and a base 26. The lens barrel 1 has a first cavity extending along a first direction. Within the first cavity, a lens module 2 and an arc-shaped heat-conducting plate 3 are sequentially arranged along the first direction. The side of the lens module 2 closest to the arc-shaped heat-conducting plate 3 abuts against the arc-shaped heat-conducting plate 3 (in some applications, the lens module 2 can directly abut against the arc-shaped heat-conducting plate 3; in other applications, conductive foam and thermally conductive silicone can be arranged between the lens module 2 and the arc-shaped heat-conducting plate 3 to achieve indirect contact). This facilitates the transfer and dissipation of heat from the lens module 2 to the arc-shaped heat-conducting plate 3, helping to reduce the temperature of the lens module 2 and improve shooting quality. A pitch motor 5 is arranged along a second direction between the first end of the top cover 4 and the side wall of the lens barrel 1. The pitch motor 5 drives the lens barrel 1 to rotate around the pitch axis. The bottom cover 6 is connected to the second end of the top cover 4. A yaw motor 27 is arranged in the third direction within the second cavity formed between the top cover 4 and the bottom cover 6. The yaw motor 27 is used to drive the lens barrel 1 to rotate around the yaw axis. The base 26 is connected to the stator of the yaw motor 27. The base 26 has a third cavity, in which a control module is arranged. The lens module 2, the pitch motor 5, and the yaw motor 27 are all electrically connected to the control module, which facilitates the automatic rotation of the lens module 2 within the lens barrel 1 around the pitch axis of the pitch motor 5 and the yaw axis of the yaw motor 27, thereby meeting the user's requirements for the shooting angle without manual operation and improving the user experience.

[0037] Specifically, a light panel 7 is provided inside the second end of the shaft top cover 4, and the pitch motor 5 is connected to the light panel 7 via a ribbon cable 8. Specifically, the shaft top cover 4 is provided with a wire hole 402 to facilitate the passage of the ribbon cable 8. A lamp hole 403 is provided on the side wall of the second end of the shaft top cover 4, and the lamp hole 403 is at the same height as the light panel 7. The light panel 7 mainly includes a driver integrated circuit for a three-color lamp and a connector. For example, by turning the light panel 7 to green, blue, or purple, it indicates that the gimbal camera is in different working states.

[0038] Furthermore, the control module includes a motherboard 9 and a gimbal control board 10. The motherboard 9 and the gimbal control board 10 are interconnected via onboard connectors. The lens module 2 is electrically connected to the motherboard 9 via a coaxial cable 11. The light board 7 is electrically connected to the gimbal control board 10 via a first connecting wire 12.

One end of the spring 15 is fixedly connected to the adapter plate 14, and the other end of the spring 15 elastically abuts against the microphone board 16. The microphone board 16 is electrically connected to the main board 9. The microphone board 16 mainly includes microphone components and connectors, providing a sound recording function to capture sound signals and convert them into electrical signals for further processing and transmission. In this embodiment, the spring 15 is made of stainless steel.

[0040] Furthermore, the gimbal camera also includes a bottom cover 17, which is connected to the base 26 and is used to seal the third cavity.

[0041] Furthermore, the gimbal camera also includes a magnetic guide plate 18, and at least one magnetic element 19 is fixedly disposed on the inner wall of the bottom cover 17. The magnetic element 19 is attracted to the magnetic guide plate 18. By adding a magnetic element 19 to the bottom cover 17, it is easy to fix the gimbal camera to the corresponding bracket or worktable by magnetic attraction. The N pole of one magnetic element 19 faces upward, and the N pole of the other magnetic element 19 faces downward. The magnetic guide plate 18 is disposed between the two magnetic elements 19 to guide the direction of the magnetic field lines to extend along the magnetic guide plate 18, thereby enhancing the attraction force and reducing the impact on the magnetic ring on the stator of the yaw motor 27. In this embodiment, motor control boards are installed on the stator of both the pitch motor 5 and the yaw motor 27. The motor control board mainly includes Hall sensors and connectors, and is mainly responsible for the motor position sensing function to detect the rotation angle of the motor.

[0042] Furthermore, silicone feet 20 are provided on the bottom wall of the bottom cover 17. In this embodiment, the bottom cover 17 is made of metal. By adding silicone feet 20, direct contact and scratches between the bracket or workbench and the metal bottom cover 17 are prevented. Even further, the gimbal control board 10 is provided with an expansion interface, and the bottom cover 17 is provided with a clearance hole 171, into which the expansion interface extends. The expansion interface can be a PogoPin or an onboard connector, a precision connector widely used in various electronic products.

The counterweight 21 is fixedly connected to the connecting part 301. The counterweight 21 is installed on the arc-shaped heat-conducting plate 3 using screws or other fasteners, so that the overall center of gravity of the telescope barrel 1 and its internal components coincides with the axis of the pitch motor 5, thus preventing the telescope barrel 1 from becoming unbalanced when rotating.

[0044] Furthermore, the gimbal camera also includes a lens decorative ring 22 and a rear cover 23, which are respectively disposed at opposite ends of the lens barrel 1. The lens decorative ring 22 and the rear cover 23 are used to seal the first cavity, protect the internal components of the lens barrel 1 from collisions with external objects, and also serve to provide waterproofing and dustproofing.

[0045] Furthermore, the side wall of the lens barrel 1 is provided with an assembly opening 101, and the inner wall surface of the assembly opening 101 is provided with a plurality of first connecting holes 1011 spaced apart circumferentially. The housing of the pitch motor 5 is provided with a plurality of second connecting holes 501 spaced apart circumferentially.
