Description

Technical Field

[0001] The utility model relates to the technology of camera manufacturing, and particularly relates to a lens assembly component with an adjustable shooting angle. Background Art

[0002] Multi-lens multi-direction cameras are relatively common camera devices. A multi-lens multi-direction camera includes multiple lenses, and the multiple lenses are distributed on the circumference of the multi-lens camera to achieve multi-direction monitoring. Multi-lens multi-direction cameras are divided into fixed multi-lens multi-direction cameras and adjustable multi-lens multi-direction cameras according to whether the lenses are fixed. Each lens of the adjustable multi-lens multi-direction camera can be independently adjusted in four axes, that is, each lens can be adjusted in the H direction (horizontal), V direction (vertical), R direction (self-rotation), and T direction (twisting), so as to achieve multi-direction adjustment of the lens shooting angle. Multiple lenses in multiple directions can achieve multi-aspect and multi-scene monitoring, achieving the purpose of one camera replacing multiple independent cameras.

[0003] Currently, the angle adjustment of the lens mostly relies on a screw-locking structure, that is, the lens usually uses fastening screws for locking. When adjustment is required, the operator needs to loosen the screws before rotating the lens. Obviously, the operation of adjusting the lens angle requires the operator to frequently loosen and tighten the screws, which has the problems of cumbersome operation and low adjustment efficiency. Moreover, it also increases the screw locking in production and assembly, making the entire production process more cumbersome. Summary of the Utility Model

[0004] Therefore, in view of the above problems, the utility model proposes a lens assembly component with an adjustable shooting angle and a camera with the lens assembly component.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The utility model proposes a lens assembly component with an adjustable shooting angle, including a lens component and a carrier. A slide rail is provided on the carrier. The lens component includes a first bracket, a second bracket, and a lens body. The first bracket is slidably connected to the slide rail. The second bracket and the first bracket are rotatably connected. The lens body further includes a top cover and a base. The base and the second bracket are rotatably connected. The top cover and the base are rotatably connected. And the rotation axis of the second bracket relative to the first bracket intersects with the rotation axis of the base relative to the second bracket. And it further includes a sliding damping member, a first rotational damping member, a second rotational damping member, and a third rotational damping member. The sliding damping member is used to provide a damping force for the sliding of the first bracket on the slide rail. The first rotational damping member is used to provide a damping force for the rotation of the second bracket relative to the first bracket. The second rotational damping member is used to provide a damping force for the rotation of the base relative to the second bracket.

[0021] To further illustrate each embodiment, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] Now, the present invention will be further described in conjunction with the accompanying drawings and the detailed implementation manners.

[0023] Embodiment 1:

[0024] Refer to Figures 1 - 3 As shown, as a preferred embodiment of the present invention, a lens assembly component with adjustable shooting angle is provided, including a lens assembly 10 and a carrier 20. The carrier 20 is used to load the lens assembly 10. In this embodiment, Figure 1 only one lens assembly 10 is shown, but actually there can be multiple lens assemblies 10 loaded on the carrier 20. The lens assembly 10 further includes a first bracket 1, a second bracket 2, and a lens body 3. A slide rail 201 is provided on the carrier 20, and the slide rail 201 extends into a circular shape that is connected end to end. The first bracket 1 is slidably connected to the slide rail 201, so that the lens assembly 10 can slide along the slide rail 11. Since the slide rail 201 is circular, the sliding of the lens assembly 10 along the slide rail 201 is equivalent to the rotation of the lens assembly 10 around the central axis H of the slide rail 201. Then, as long as the lens assembly 10 is made to slide along the slide rail 201, the rotational position of the lens assembly 10 along the central axis H can be adjusted, that is, the so-called H-direction rotation adjustment in the art.

[0025] A sliding damping member 4 is fixedly connected to the first bracket 1 and is used to provide a damping force for the sliding of the first bracket 1 on the slide rail 201. In this embodiment, the slide rail 201 is a groove structure, and the sliding damping member 4 is an arc-shaped elastic piece fixed on the first bracket 1. The arc-shaped convex direction of the sliding damping member 4 faces the groove side wall of the slide rail 201. When the first bracket 1 is connected to the slide rail 201, the sliding damping member 4 presses against the groove side wall of the slide rail 201 with an elastic restoring force. Thus, the frictional force between the sliding damping member 4 and the slide rail 201 forms the sliding damping of the first bracket 1 on the slide rail 201. Only by applying a driving force greater than this frictional force to the first bracket 1 can the first bracket 1 be driven to slide along the slide rail 11, otherwise the first bracket 1 will get stuck and form a self-locking effect.

[0026] In this embodiment, the sliding damping member 4 is implemented in the form of an elastic member. However, the sliding damping member 4 can also be replaced with a damping member made of other materials such as silica gel or rubber. In other embodiments, the sliding damping member 4 can also be fixed on the slide rail 201. The slide rail 201 is a groove in this embodiment. However, in other embodiments, it can also be a convex rail structure.

[0027] The second bracket 2 and the first bracket 1 are rotatably connected. For example, Figures 3 - 5 as shown, an annular boss 11 is provided at one end of the first bracket 1 facing the second bracket 2, and an annular groove 21 is provided at one end of the second bracket 2 facing the first bracket 1. The annular boss 11 and the annular groove 21 are inserted and matched to form the rotatable connection between the second bracket 2 and the first bracket 1. In addition, any other form of rotatable connection can also be used to achieve the rotatable connection between the second bracket 2 and the first bracket 1. The rotation axis of the rotatable connection between the second bracket 2 and the first bracket 1 is the axis T. By rotating the second bracket 2 relative to the first bracket 1, the rotational position of the second bracket 2 around the axis T can be adjusted, that is, the so-called T-direction rotation adjustment in the art.

[0028] The first rotational damping member 5 is fixed on the second bracket 2 and is used to provide a damping force for the rotation of the second bracket 2 relative to the first bracket 1. In this embodiment, the first rotational damping member 5 is a wave spring. A through hole 12 is provided on the first bracket 1. The second bracket 2 and the first rotational damping member 5 are fixedly connected by screws passing through the through hole 12. Thus, the first bracket 1 is clamped between the second bracket 2 and the first rotational damping member 5. The first rotational damping member 5 always presses against the first bracket 1 by elastic force. The frictional force between the first rotational damping member 5 and the first bracket 1 forms the rotational damping of the second bracket 2. Only by applying a driving force greater than this frictional force to the second bracket 2 can the second bracket 2 be driven to rotate relative to the first bracket 1. Otherwise, the second bracket 2 will be stuck and form a self-locking effect.

[0029] By adopting the first rotational damping member 5 of this embodiment and the assembly structure of the first bracket 1 and the second bracket 2, the first bracket 1 can be always clamped between the second bracket 2 and the first rotational damping member 5 by the pressing of the screws, ensuring that the first rotational damping member 5 reliably provides a damping effect. To avoid contact between the first rotational damping member 5 and the carrier 20, a relief groove for the first rotational damping member 5 is provided on the first bracket 1 in this embodiment.

[0030] Such as Figure 3 and Figure 4, the lens body 3 further includes a top cover 32 and a base 31. The base 31 is rotatably connected to the second bracket 2 with the axis of rotation being axis V, and axis T and axis V intersect. By rotating the base 31 relative to the second bracket 2, the rotational position of the base 31 around axis V can be adjusted, which is the so-called V-direction rotational adjustment in the art. The second rotational damping member 6 provides a damping force for the rotation of the base 31 relative to the second bracket 2. In this embodiment, the second rotational damping member 6 is a rubber ring disposed between the relative rotational surfaces of the base 31 and the second bracket 2.

[0031] The top cover 32 and the base 31 are rotatably connected with the axis of rotation being axis R. By rotating the top cover 32 relative to the base 31, the rotational position of the top cover 32 around axis R can be adjusted, which is the so-called R-direction rotational adjustment in the art. The third rotational damping member 7 is used to provide a damping force for the rotation of the top cover 32 relative to the base 31. As Figure 6 , in this embodiment, the base 31 further includes a middle cover 311 and a bottom cover 312. The bottom cover 312 and the top cover 32 are respectively disposed on both sides of the middle cover 311. The top cover 32 passes through the middle cover 311 and is fixedly connected to the bottom cover 312. The top cover 32 passing through the middle cover 311 forms a rotatable connection with the middle cover 311. The third rotational damping member 7 is a wave spring clamped between the middle cover 311 and the top cover 32.

[0032] In this embodiment, different solutions are proposed for the rotational mating structure and the rotational damping structure in multiple rotational directions, aiming to illustrate that as long as the first rotational damping member 5, the second rotational damping member 6, and the third rotational damping member 7 can provide rotational damping, elastic members, silica gel, and rubber are all optional damping members. And according to the different rotational damping members, different rotational mating structures can also be adaptively adopted between two rotatable components.

[0033] The first bracket 1, the second bracket 2, the base 31, and the top cover 32 and other rotatable components together constitute the multi-directional angle adjustment function of the lens assembly component of this embodiment. When the lens assembly component of this embodiment does not need to adjust the shooting angle, due to the self-locking effects of the sliding damping member 4, the first rotational damping member 5, the second rotational damping member 6, and the third rotational damping member 7, each rotatable component can be locked. When it is necessary to adjust the shooting angle, only by applying a driving force greater than the damping force to the corresponding rotatable component, the angle can be adjusted, achieving the purpose of adjusting the monitoring angle without tools, making the installation of the camera more convenient and enabling it to quickly adjust to the required monitoring area.

[0035] This embodiment provides a camera, which can be a multi-lens multi-directional camera. This camera includes the lens assembly component of Embodiment 1 and has the same structure and equivalent technical effects.
