A gimbal camera device

Abstract

This invention belongs to the field of photographic device technology and discloses a gimbal camera device. The gimbal camera device includes a lens barrel, a driving component, a lens, a fixing component, and a flexible component. The driving component is fixed inside the lens barrel. One end of the lens is fixedly connected to the output end of the driving component, and the other end is rotatably connected to the lens barrel. The driving component drives the lens to rotate around its axis. The driving component and the lens are connected via the fixing component, and the flexible component is disposed between the lens barrel and the fixing component. The connection between the driving component and the lens barrel via the fixing component allows the lens to be fixed inside the lens barrel while rotating around its axis without lens eccentricity. The flexible component prevents excessive constraint on the driving component when fixed to the lens barrel, thus making the rotation of the driving component more stable, and consequently, the rotation of the lens more stable.

Furthermore, the connection structure between the lens and the lens barrel is simple and easy to operate.

Description

Technical Field

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

[0002] 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.

[0003] 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.

[0004] 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 stringent screw fastening, 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

[0005] The purpose of this invention is to provide a gimbal camera device that allows the lens to rotate around its axis within the lens barrel without becoming eccentric or being affected by internal stress, thereby ensuring image quality. Furthermore, the connection structure between the lens and the lens barrel is simple and easy to operate.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0045] like Figures 1 to 8 As shown, 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 component 2, a lens 3, a rotating component 6, a fixing component 4, and a flexible component 5. The drive component 2 is fixed inside the lens barrel 1; one end of the lens 3 is fixedly connected to the output end of the drive component 2, and the other end is rotatably connected to the lens barrel 1. The drive component 2 is used to drive the lens 3 to rotate around its axis; the drive component 2 and the lens 3 are connected by the fixing component 4. A limiting part 14 is provided on the inner wall of the end of the lens barrel 1 rotatably connected to the lens 3, and the end face of the rotating component 6 abuts against the limiting part 14; the flexible component 5 is disposed between the lens barrel 1 and the fixing component 4. Specifically, the flexible component 5 is made of silicone or rubber. The lens 3 is rotatably connected to the lens barrel 1 through the drive component 2. The drive component 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.

[0046] The driving component 2 allows the lens 3 to rotate around its axis within the lens barrel 1. The driving component 2 is fixed inside the lens barrel 1. One end of the lens 3 is fixedly connected to the driving component 2, and the other end is rotatably connected to the lens barrel 1, ensuring that the lens 3 can rotate normally without eccentricity. The driving component 2 and the lens barrel 1 are connected by a fixing component 4, allowing the lens 3 to be positioned inside the lens barrel 1 and rotate around its axis. A flexible component 5 is located between the lens barrel 1 and the fixing component 4, preventing excessive constraint on the driving component 2 when fixed to the lens barrel 1. This makes the rotation of the driving component 2 more stable, thus making the rotation of the lens 3 more stable. This ensures that the lens 3 does not become eccentric during rotation and that there is no internal stress on the lens 3, thereby ensuring image quality. Furthermore, the connection structure between the lens 3 and the lens barrel 1 is simple and easy to operate.

[0047] like Figure 3 , Figure 5 and Figure 6 As shown, to allow the lens 3 to rotate more smoothly within the lens barrel 1, the gimbal camera device also includes a rotating component 6. A limiting part 14 is provided on the inner wall of the end of the lens barrel 1 that is rotatably connected to the lens 3, and the end face of the rotating component 6 abuts against the limiting part 14. Specifically, the rotating component 6 is a bearing; one end face of the bearing abuts against the limiting part 14, and the other side is fixed inside the lens barrel 1 with adhesive. The bearing reduces friction between the lens 3 and the lens barrel 1, protecting both and extending their lifespan. After wear occurs due to rotation, only the rotating component 6 needs to be replaced, without needing to replace the lens 3 or the lens barrel 1, thus saving costs. The inner ring of the rotating component 6 mates with the lens 3, and the outer ring of the rotating component 6 connects to the inner wall of the lens barrel 1.

[0048] like Figure 2 Figure 4 , Figure 6 and Figure 7 As shown, in order to facilitate the connection and fixation of the lens barrel 1 and the drive member 2 by the fixing member 4, the lens barrel 1 includes a lens barrel body 11 and a connecting part 12. The connecting part 12 is disposed on the inner wall of the lens barrel body 11 and extends to the inner side of the lens barrel body 11. The connecting part 12 is used to connect the fixing member 4.

[0049] Specifically, the fixing member 4 includes a first bolt 41, the connecting part 12 is provided with a through hole 121, the driving member 2 is provided with a first connecting hole 21, the flexible member 5 is a flexible washer, the first bolt 41 passes through the flexible washer and the through hole 121 in sequence and is placed in the first connecting hole 21, and is threadedly connected to the first connecting hole 21.

[0050] Furthermore, to make the connection between the lens barrel 1 and the driving component 2 more stable, a plurality of fixing members 4, flexible members 5, and connecting parts 12 are provided. The plurality of connecting parts 12 are evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, and the plurality of fixing members 4, flexible members 5, and connecting parts 12 are respectively arranged in a one-to-one correspondence. Specifically, in this embodiment, there are 5 fixing members 4, flexible members 5, and connecting parts 12, and the 5 connecting parts 12 are evenly distributed along the circumference of the lens barrel 1 on the inner wall of the lens barrel body 11, and the 5 fixing members 4, 5 flexible members 5, and 5 connecting parts 12 are respectively arranged in a one-to-one correspondence. In other embodiments, the number of fixing members 4, flexible members 5, and connecting parts 12 may be 2, 3, 4, or 6, but this is not a limitation.

[0051] like Figure 2 and Figure 7 As shown, to make the connection between the lens barrel 1 and the drive component 2 more stable, one of the inner walls of the lens barrel 1 and the other of the side of the drive component 2 are provided with a protrusion 13 and a groove 22, respectively, with the protrusion 13 abutting against the inner wall of the groove 22. In this embodiment, the inner wall of the lens barrel 1 is provided with a protrusion 13, and the side of the drive component 2 is provided with a groove 22, with the protrusion 13 abutting against the inner wall of the groove 22. Specifically, to further make the connection between the drive component 2 and the lens barrel 1 more stable during operation, so that the drive component 2 does not jump when the internal shaft of the drive component 2 rotates, there are two protrusions 13 in the circumferential direction of the lens barrel 1, and correspondingly, there are two grooves 22 on the side of the drive component 2, with the two protrusions 13 and the two grooves 22 corresponding to each other. In other embodiments, there may be 3, 4, or 5 protrusions 13 and grooves 22 in the circumferential direction of the lens barrel 1, but this is not a limitation. In another embodiment, the inner wall of the lens barrel 1 may be provided with a groove, and the side of the drive member 2 may be provided with a protrusion. The protrusion abuts against the inner wall of the groove. The number of protrusions and grooves may be 1, 2, 3, 4 or 5, but is not limited thereto.

[0052] like Figure 4 , Figure 5 and Figure 7 As shown, to facilitate the connection between the drive component 2 and the lens 3, the drive component 2 is provided with a second connecting hole 23. The gimbal camera device also includes a connector 8. The lens 3 is provided with a lens connecting hole 31. The connector 8 passes through the second connecting hole 23 and the lens connecting hole 31 in sequence, threading the lens 3 to the drive component 2. Specifically, the connector 8 is a second bolt. The drive component 2 includes a fixed part and a rotating part, which are rotatably connected. To allow the lens 3 to rotate smoothly, the rotating part of the drive component 2 is connected to the lens 3. The fixed part is provided with a clearance hole 24 that coincides with the axis of the second connecting hole 23. The second connecting hole 23 is a countersunk hole. After installation, the countersunk hole makes the appearance of the drive component 2 and the lens 3 smoother and cleaner, preventing the head of the second bolt from protruding from the surface of the drive component 2, reducing the risk of injury from touching or collision caused by the protruding head of the second bolt. The clearance hole 24 facilitates the installation and removal of the connector 8.

[0053] like Figure 1 As shown, in order to allow the gimbal camera device to be connected to other products, the outer wall of the lens barrel 1 is provided with a mounting part 7. Figure 8 As shown, the gimbal camera device also includes a support assembly 100. The outer wall of the lens barrel 1 is provided with a mounting portion 7, which is connected to the support assembly 100. Specifically, the support assembly 100 includes a support base 101 and a support arm 102. The support arm 102 is connected to the support base 101, and its output end is connected to the mounting portion 7, allowing the gimbal camera device to rotate. The support assembly 100 serves to support and bear the lens barrel 1.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
