Description

Technical Field

[0001] This utility model relates to the field of camera technology, specifically to a camera lens light-shielding structure. Background Technology

[0002] In modern surveillance, security, and various image acquisition fields, cameras are widely used as core equipment. To achieve more flexible shooting angles, some cameras integrate mechanical pan-tilt units to control lens rotation. As a key imaging component, the lens needs to be surrounded by appropriate structures to reduce external stray light interference and ensure clear imaging. The lens light-blocking structure is an important component of this, which is closely related to the overall performance of the camera and directly affects the quality of image acquisition.

[0003] Existing camera lens light-blocking structures have many shortcomings. The rotation gap generated when the lens rotates cannot be effectively compensated, resulting in incomplete light blocking. Stray light can easily enter and affect the image, seriously impacting the quality of post-production video recording. To address this, we propose a new camera lens light-blocking structure.

The light-shielding component is located inside the camera cover 2. The light-shielding component includes a hard plastic base 4 and a soft plastic base 5. The hard plastic base 4 and the soft plastic base 5 are pressed together by a hot press mold, and the light-shielding component is sleeved and fitted with the lens 3.

[0018] Furthermore, a mating hole 10 is provided in the center of the side wall of the camera housing 1. The lens 3 passes through the interior of the mating hole 10, and a rotation gap 11 is formed between the cylindrical side wall of the lens 3 and the mating hole 10. The rotation gap 11 provides rotation space for the lens 3.

[0019] Furthermore, the support frame 6 has an L-shaped plate structure, and the bottom of the support frame 6 is provided with two trapezoidal sliding strips 9 that are symmetrically distributed. The support frame 6 plays a supporting and connecting role.

[0020] Furthermore, a trapezoidal groove 18 is provided at the top of the connecting strip 17, and one side of the trapezoidal groove 18 is open. The trapezoidal groove 18 is slidably connected with the trapezoidal slide bar 9. An elastic cavity 19 is provided inside the connecting strip 17. The elastic cavity 19 is located inside the connecting strip 17 corresponding to the open side of the trapezoidal groove 18. The trapezoidal groove 18 and the trapezoidal slide bar 9 can greatly improve the stability of the connection by sliding in a trapezoidal fit, preventing loosening and ensuring the image quality. The four corners of the base 7 are connected to the fixed position of the camera by adapter bolts or screws.

[0021] Furthermore, the top of the elastic cavity 19 is provided with a telescopic hole 20, which is connected to the bottom of the trapezoidal groove 18. The inner wall of the elastic cavity 19 is provided with a sliding groove 21. When installing the top component, the two trapezoidal slide bars 9 at the bottom of the support frame 6 are aligned with the trapezoidal groove 18.

At this time, the trapezoidal slide bar 9 can be inserted and removed.

[0023] Furthermore, the soft rubber base 5 has a soft rubber tube 13 on its side wall, which mates with the mating hole 10.

The soft rubber tube 13 has good flexibility and tensile properties, so that the lens 3 is surrounded by the arc-shaped soft rubber cover 14 no matter which angle it turns. Therefore, it can effectively cover the rotation gap 11. Specifically, when the lens 3 rotates to the right, the arc-shaped soft rubber cover 14 on the right side is compressed and retracted, while the arc-shaped soft rubber cover 14 on the left side pops up and fits against the lens 3 due to the V-shaped telescopic groove 15. Therefore, it can effectively cover the huge rotation gap 11 left on the left side. In addition, the surface of the light-shielding component is coated with anti-static hand feel oil, which greatly improves the aesthetic experience of the product.

[0024] Furthermore, the hard plastic base 4 has a hard plastic cylinder 12 on its side wall. The hard plastic cylinder 12 is heat-pressed into the cylindrical groove 16.

[0026] Working principle: Install the camera lens light-shielding structure correctly according to the diagram. In terms of light shielding, the hard rubber base 4 and soft rubber base 5 in the light-shielding assembly are pressed together by a hot-press mold. The hard rubber cylinder 12 on the side wall of the hard rubber base 4 is hot-pressed into the cylindrical groove 16 inside the arc-shaped soft rubber cover 14 of the soft rubber base 5. The hard rubber base 4 acts as a skeleton, facilitating connection with the soft rubber base 5. Both are fitted to the inner wall of the camera cover 2 via matching screws, and the entire assembly is fitted to the lens 3.
