Description

Gimbal camera equipment

[0001] This application claims priority to Chinese Patent Application No. 202422120011.5, filed with the Chinese Patent Office on August 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of photographic apparatus technology, such as a gimbal camera device. Background Technology

[0003] A gimbal camera typically consists of a rotating base, a lens barrel, and a lens, with the lens fixed inside the lens barrel. For heavy-duty, large lenses, an L-shaped adapter is usually used to connect the lens to the lens barrel. The long side of the L-shaped adapter is fixed to the side of the lens, and the short side of the L-shaped adapter is fixed to the inner wall of the lens barrel, thus achieving the connection and fixation between the lens and the lens barrel.

[0004] When using an L-shaped adapter to fix the side of the lens, due to the large load on the lens, one end of the lens is embedded in the lens barrel, and the other end is fixedly connected to the lens barrel through the L-shaped adapter, in order to avoid the problem of the lens being too heavy and causing the lens to be misaligned when connected to the lens barrel.

[0005] The L-shaped adapter design restricts the lens to its internal position within the lens barrel, preventing rotation around its axis. This connection method demands high precision in the manufacturing of the L-shaped adapter and meticulous screw-locking, requiring a 90° angle between the two sides, making manufacturing and installation challenging. Since one end of the lens is embedded in the lens barrel, and the other end is fixed there via the L-shaped adapter, internal stress can easily occur, potentially leading to lens misalignment and affecting image quality. Summary of the Invention

[0033] As shown in Figures 1 to 5, this embodiment provides a gimbal camera device applicable to fields such as cameras and camcorders. In some embodiments, the gimbal camera device includes a lens barrel 1, a drive unit 2, a lens 3, a connector 4, a fixing component, and a flexible component 5. The drive unit 2 is fixed inside the lens barrel 1; the lens 3 includes a tail end 31, a lens element end 32, and a lens side 33, and the output end of the drive unit 2 is connected to the tail end 31. The drive unit 2 is configured to drive the lens 3 to rotate around its own axis; the fixing component passes through the connector 4, and the lens side 33 and the side of the output end of the drive unit 2 are connected to the fixing component via the connector 4; the flexible component 5 is disposed between the fixing component and the connector 4. Exemplarily, the flexible component 5 is made of silicone or rubber, and the drive unit 2 can be a motor, the output end of which is connected to the lens 3, and the motor speed can be controlled by controlling the current of the motor. In other embodiments, the flexible component 5 can also be made of plastic, but is not limited thereto.

[0034] The drive component 2 allows the lens 3 to rotate around its own axis within the lens barrel 1 without eccentricity. The drive component 2 is connected to the lens barrel 1 via a fixing component, allowing the lens 3 to be fixed within the lens barrel 1 while rotating around its own axis. The flexible component 5 prevents excessive constraint on the drive component 2 when fixed to the lens barrel 1, thus making its rotation more stable. This, in turn, makes the rotation of the lens 3 more stable, ensuring that the lens 3 does not eccentricate during rotation and that its internal structure is free from stress, thereby ensuring image quality.

[0035] To facilitate the connection of lens 3 and drive component 2 to connector 4, connector 4 is plate-shaped and includes a connecting plate with a first connecting portion 41 and a second connecting portion 42.

In this embodiment, there are four first through holes 411. Correspondingly, there are four first screws 61, four flexible washers, and four first connecting holes 34. The four first through holes 411 are respectively located at the four corners of the first connecting part 41. The arrangement of the four first through holes 411 makes the connection between the connector 4 and the lens side 33 more stable.

[0037] Optionally, the fixing assembly also includes a second screw 62, the flexible member 5 is a flexible washer, the rotating part 22 of the driving member 2 is provided with a first fixing hole 221, the second connecting part 42 is provided with a second through hole 421, and the second screw 62 passes through the flexible washer and the second through hole 421 in sequence and is threadedly connected to the first fixing hole 221. In this embodiment, there are two second through holes 421, and correspondingly, there are two second screws 62, two flexible washers, and two first fixing holes 221. The arrangement of two second through holes 421 makes the connection between the connecting member 4 and the driving member 2 more stable.

[0038] To facilitate the connection between the lens barrel 1 and the drive unit 2, the gimbal camera device also includes a first fastener 63. The lens barrel 1 includes a lens barrel body 11 and a protrusion 12. The protrusion 12 is disposed on the inner wall of the lens barrel body 11 and extends toward the inner side of the lens barrel body 11. The first fastener 63 connects the lens barrel body 11 and the drive unit 2 through the protrusion 12. For example, the first fastener 63 is a third screw. The protrusion 12 is provided with a through hole 121, and the drive unit 2 is provided with a third fixing hole 25. The third screw passes through the through hole 121 and is threadedly connected to the third fixing hole 25.

[0039] To ensure a more stable connection between the lens barrel 1 and the drive component 2, multiple first fasteners 63 and protrusions 12 are provided. These protrusions 12 are evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, with each first fastener 63 and protrusion 12 corresponding to the other. In this embodiment, five first fasteners 63 and five protrusions 12 are provided, evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, with each first fastener 63 and protrusion 12 corresponding to the other.
