Description

Technical Field

[0001] This utility model relates to the field of supplementary lighting, and in particular to a camera device. Background Technology

[0002] A dome camera mainly consists of a base, a camera, and a fill light. The camera rotates and is mounted on the base, while the fill light is fixed to the camera so it rotates with the camera on the base. Because dome cameras need to meet IP67 or IK10 protection standards, they often also include a dome housing, with the camera and fill light located inside the housing. When the camera rotates at a large angle, the light emitted by the fill light will be reflected by the base and dome housing and absorbed by the camera, causing problems such as infrared crosstalk, image blurring, and blurred images. Utility Model Content

[0003] Therefore, it is necessary to provide a camera device to address the problem of poor image quality when the camera rotates at a large angle.

[0004] A camera device includes a base and a camera unit. The camera unit includes a lens, a rotating base, and a fill light assembly. The lens is mounted on the rotating base, which is rotatably disposed on the base. The fill light assembly is movably disposed on the rotating base.

[0005] The supplementary lighting assembly of this invention is mounted on the rotating base and revolves around the lens.

[0006] The camera unit of this utility model further includes a guide rib, which is mounted on the rotating base to form a guide groove with the rotating base. The guide groove extends along the circumference of the lens, and the supplementary lighting component is located at the guide groove.

[0007] The guide groove of this invention is provided with a first locking tooth on its side wall, and the supplementary lighting component is provided with a second locking tooth, wherein the first locking tooth and the second locking tooth mesh.

[0008] The first locking tooth of this invention has a first deformation cavity in the middle, and / or the second locking tooth has a second deformation cavity in the middle.

[0009] In this invention, at least one of the first and second locking teeth has an arc shape.

[0010] The supplementary lighting assembly of this utility model is provided with a paddle, the edge of the guide rib is recessed to form a first clearance opening with the rotating seat, the first clearance opening extends along the circumference of the lens, and the paddle passes through the first clearance opening so that the paddle is at least partially located outside the guide groove.

[0011] The camera unit of this utility model includes a light-transmitting cover plate, which is installed at the opening of the guide groove to block the supplementary lighting component.

[0012] The base of this utility model is provided with a clearance groove, the rotating seat is at least partially located in the clearance groove, and the lens and the fill light assembly are both located outside the clearance groove.

[0013] The camera unit of this utility model also includes a main control board. A control room is provided inside the rotating base. The main control board is installed in the control room. The supplementary lighting component is electrically connected to the main control board through a flexible wire. A second clearance opening is provided on the side wall of the control room. The flexible wire passes through the second clearance opening.

[0014] The beneficial effects of this utility model are as follows:

[0015] Since the fill light assembly is movable on the rotating mount, after rotating the mount to adjust the lens shooting angle, the position of the fill light assembly on the rotating mount can be adjusted independently. This changes the light path of the light emitted by the fill light assembly, reducing the occurrence of light from the fill light assembly entering the lens, thereby reducing the adverse effects of the fill light assembly on the lens image quality.

[0035] Example:

[0036] See Figure 1 This embodiment provides a camera device, including a base 1, a camera unit 2, and a housing 3. The base 1 has a clearance groove 11, and the camera unit 2 is rotatably mounted in the clearance groove 11. The camera unit 2 adjusts its shooting angle by rotating, and the base 1 avoids the rotational movement of the camera unit 2 through the clearance groove 11. The housing 3 is mounted on the base 1 to protect the camera unit 2, thereby meeting the protection level requirements of the camera device.

[0037] See details Figure 2 , Figure 4 , Figure 6 and Figure 8 The camera unit 2 includes a lens 21, a rotating base 22, and a fill light assembly 23, with both the lens 21 and the fill light assembly 23 mounted on the rotating base 22.

[0038] Specifically, the rotating base 22 includes a first rotating housing 222 and a second rotating housing 223. The first rotating housing 222 is rotatably mounted on the base 1, and the second rotating housing 223 is rotatably mounted on the first rotating housing 222. The lens 21 is fixed on the second rotating housing 223. The rotation axis of the first rotating housing 222 is perpendicular to the axis of the lens 21, and the rotation axis of the second rotating housing 223 coincides with the axis of the lens 21. The shooting angle of the lens 21 can be adjusted by rotating the first rotating housing 222 and the second rotating housing 223 together or by rotating one of them alone.

[0039] Unlike existing technologies, in this embodiment, the supplementary lighting component 23 is movably mounted on the rotating base 22.

[0040] Specifically, the fill light assembly 23 is movably mounted on the second rotating housing 223, thereby changing its relative position with the base 1. This prevents or reduces the occurrence of the base 1 reflecting the fill light into the lens 21, ensuring the shooting quality of the lens 21. Since the movement of the fill light assembly 23 on the second rotating housing 223 is independent of the rotation of the second rotating housing 223 on the first rotating housing 222 and the rotation of the first rotating housing 222 on the base 1, the movement of the fill light assembly 23 on the second rotating housing 223 will not cause a change in the shooting angle of the lens 21.

[0041] See Figure 7 and Figure 9 The fill light assembly 23 is equipped with a lever 233, which can be manipulated to control the movement of the fill light assembly 23 on the rotating base 22.

[0042] To more clearly illustrate the technical effects of the camera device in this embodiment, combined with... Figures 2-5 Further details are provided. The camera unit 2 also includes a light-transmitting cover plate 26, which is mounted on the second rotating housing 223 and covers the supplementary lighting component 23 to allow the supplementary lighting light from the supplementary lighting component 23 to be transmitted through the light-transmitting cover plate 26.

[0043] See details Figure 2 and Figure 3At this point, the shooting angle of lens 21 is correct, but the position of the fill light assembly 23 (corresponding to the location of the lever 233) is poor. The light emitted by the fill light assembly 23, after being transmitted through the light-transmitting cover 26, hits the base 1 and is reflected before entering the lens 21, resulting in a decrease in the image quality of lens 21. To solve the above problem, please refer to [link / reference needed]. Figure 4 and Figure 5 By moving the lever 233, the position of the fill light assembly 23 on the second rotating housing 223 changes, and correspondingly, the relative position between the fill light assembly 23 and the base 1 also changes, increasing the distance between the fill light assembly 23 and the base 1. The base 1 can better avoid the fill light emitted by the fill light assembly 23, reducing the amount of fill light reflected and entering the lens 21, thus ensuring the shooting quality of the lens 21. At the same time, before and after moving the lever 233, neither the first rotating housing 222 nor the second rotating housing 223 rotates on the base 1. Therefore, the shooting angle of the lens 21 does not change before and after the lever 233 is moved, ensuring the normal shooting of the lens 21.

[0044] Preferably, the supplementary lighting component 23 is arranged to revolve around the lens 21 on the second rotating housing 223. In other words, no matter how the supplementary lighting component 23 moves on the second rotating housing 223, the distance between the supplementary lighting component 23 and the lens 21 can remain constant, so as to avoid significant changes in the supplementary lighting effect of the supplementary lighting component 23.

[0045] Based on this, see Figures 8-11 In this embodiment, the camera unit 2 also includes a guide rib 24, which is mounted on the second rotating housing 223 to form a guide groove 25 with the second rotating housing 223. The guide groove 25 is arc-shaped and extends circumferentially along the lens 21. The supplementary lighting assembly 23 is located at the guide groove 25 to obtain movement guidance when revolving around the lens 21.

[0046] See details Figure 9 The guide rib 24 has an inwardly recessed edge to form a first clearance opening 241 with the second rotating housing 223. The first clearance opening 241 connects to the guide groove 25 and extends circumferentially along the lens 21. The paddle 233 passes through the first clearance opening 241. During the revolution of the supplementary lighting assembly 23, the guide rib 24 avoids the paddle 233 through the first clearance opening 241. In addition, the paddle 233 is at least partially located outside the guide groove 25 via the first clearance opening 241 to facilitate control of the paddle 233.

[0047] See Figure 7 , Figure 9 and Figure 11The guide groove 25 has at least three first locking teeth 251 arranged sequentially around the lens 21 on its side wall. The fill light assembly 23 has at least three second locking teeth 231 arranged sequentially around the lens 21. The first locking teeth 251 and the second locking teeth 231 engage with each other to achieve self-locking, thereby locking the position of the fill light assembly 23 on the rotating seat 22. When the lever 233 is turned, the fill light assembly 23 is subjected to an additional rotational torque, and at least one of the first locking teeth 251 and the second locking teeth 231 deforms to allow the fill light assembly 23 to revolve around the lens 21.

[0048] Preferably, a first deformation cavity 252 is provided in the middle of the first locking tooth 251. The first deformation cavity 252 provides more deformation allowance for the first locking tooth 251, thereby enhancing the deformation capability of the first locking tooth 251. Similarly, a second deformation cavity 232 is provided in the middle of the second locking tooth 231 to enhance the deformation capability of the second locking tooth 231. After the deformation capabilities of the first locking tooth 251 and the second locking tooth 231 are enhanced, it is easier to make the supplementary lighting component 23 rotate when the lever 233 is turned. The first locking tooth 251 and the second locking tooth 231 are also less likely to break, which can significantly increase the service life of the first locking tooth 251 and the second locking tooth 231.

[0049] In this embodiment, the first locking tooth 251 and the second locking tooth 231 are both curved, so that the fill light assembly 23 can rotate more easily when the lever 233 is turned.

[0050] See Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 A light-transmitting cover plate 26 is installed at the opening of the guide groove 25. The light-transmitting cover plate 26 can limit the position of the supplementary lighting component 23 to prevent the supplementary lighting component 23 from detaching from the guide groove 25 along the axial direction of the lens 21.

[0051] Conventionally, the camera unit 2 also includes a main control board, with a control chamber housed within the rotating base 22, and the main control board installed within the control chamber. In this embodiment, the supplementary lighting component 23 is electrically connected to the main control board via a flexible wire. As the supplementary lighting component 23 revolves, the flexible wire can deform and oscillate to adapt to changes in the relative position between the supplementary lighting component 23 and the main control board. See also... Figure 7 and Figure 9 A second clearance opening 221 is provided on the side wall of the control room. Flexible wires are passed through the second clearance opening 221 to obtain the space required for swinging and deformation.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
