[0002] A computer camera is a common computer auxiliary device, which is widely used in video calls, video conferences, webcasts, etc.

[0003] Currently, computers and cameras are often used for webcasting. During the webcast, in order to achieve a specific visual effect, sometimes the angle or position of the camera needs to be adjusted. Existing computer cameras are generally clamped above the display screen by a clip. During use, the angle of the camera can be rotated left and right, and the pitch angle of the camera can also be adjusted. However, the tilt angle of the camera in the vertical plane cannot be adjusted, which limits the angle adjustment of the camera and makes it difficult to meet the diverse webcast requirements. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a computer camera aiming at the deficiencies of the prior art, and solve the technical problem that the existing computer camera cannot adjust the angle in the vertical plane.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

Under the action of relative forces, the outer frame and the inner frame will produce slight deformation, so that the outer frame slightly expands outward and becomes larger, and the inner frame slightly shrinks inward and becomes smaller, so that the inner frame can rotate inside the outer frame. After the rotation is completed, the rolling ball will stay in the concave part between the two protrusions, and the protrusions on both sides play a limiting role on the rolling ball, that is, it plays a limiting role on the rotation of the inner frame, thereby preventing the camera body from rotating without reason and affecting stability.

[0026] For the convenience of understanding, please refer to Figures 1-4 , this embodiment provides a computer camera, including: a base 3 and a camera body 7.

[0027] The main shape of the base 3 is a relatively thin cylindrical shape. An annular outer frame 9 is provided above the base 3. In the initial state, the outer frame 9 is vertically arranged. As Figure 2As shown, arc-shaped protrusions 10 are arranged in the inner wall of the outer frame 9 in the circumferential direction, and a circular inner frame 8 is arranged inside the outer frame 9. The outer frame 9 and the inner frame 8 are arranged concentrically and in the same plane. The inner side of the outer frame 9 and the outer side of the inner frame 8 are both circular, and the inner radial dimension of the outer frame 9 is slightly larger than the outer radial dimension of the inner frame 8. There is a certain gap between the outer side of the inner frame 8 and the protrusions 10 on the outer frame 9. Figures 2-4 As shown, the outer side wall of the inner frame 8 is provided with movable grooves 11 in the circumferential direction in sequence, and the shape of the movable groove 11 is the shape of a large half sphere, and the opening of the movable groove 11 faces the radial extension direction of the inner frame 8. A rolling ball 12 is provided in the movable groove 11 for rolling, and the rolling ball 12 is clearance-matched with the movable groove 11, and a part of the rolling ball 12 is exposed outside the movable groove 11, and the rolling ball 12 is transitionally matched with the protrusion 10. The material of the inner frame 8 and the outer frame 9 is plastic, and the inner frame 8 and the outer frame 9 have a certain elasticity. The protrusion 10 is specifically a hemispherical hemisphere, and the spherical diameter of the protrusion 10 is the same as the spherical diameter of the rolling ball 12.

[0028] The camera body 7 is arranged at the center position of the inner frame 8 , and the camera body 7 is connected to the inner wall of the inner frame 8 through a connecting rod 6 .

[0029] The computer camera of this embodiment is used as follows: first, the base 3 is fixed and placed, and the camera body 7 is connected to the computer. When using the camera for live broadcasting or other special purposes, it is sometimes necessary to adjust the tilt angle of the picture (similar to rotating a picture on a computer by a certain angle) to achieve a specific visual effect. At this time, one hand can be used to hold the outer frame 9 to prevent the outer frame 9 from shaking or rotating, and the other hand can be used to hold the camera body 7 or the connecting rod 6 to rotate the inner frame 8 along its own axis. During the rotation of the inner frame 8, the camera body 7 is driven to rotate in a vertical plane, and pictures with different tilt degrees can be collected through the camera body 7, thereby improving the applicability and playability of the computer camera.

[0030] It should be noted that during the rotation of the inner frame 8, the rolling ball 12 and the protrusion 10 produce a certain degree of extrusion and friction. During the extrusion and friction between the rolling ball 12 and the protrusion 10, the rolling ball 12 rolls in the movable groove 11, which helps to reduce the friction between the rolling ball 12 and the protrusion 10, making the inner frame 8 easy to rotate. Under the action of relative forces, the outer frame 9 and the inner frame 8 will produce slight deformation, causing the outer frame 9 to slightly expand outward and become larger, and causing the inner frame 8 to slightly shrink inward and become smaller, so that the inner frame 8 can rotate inside the outer frame 9. After the rotation is completed, the rolling ball 12 will stay in the concave part between the two protrusions 10, and the protrusions 10 on both sides will limit the rolling ball 12, that is, limit the rotation of the inner frame 8, thereby preventing the camera body 7 from rotating without reason and affecting stability.

[0031] In one embodiment, as Figure 4 shown, an annular groove 13 is provided circumferentially along the inner wall of the outer frame 9. The opening of the annular groove 13 faces the center of the outer frame 9, and the protrusion 10 is arranged in the annular groove 13. The inner frame 8 is embedded in the annular groove 13 of the outer frame 9 and rotates inside the annular groove 13. The annular groove 13 functions to limit the inner frame 8 and prevent the inner frame 8 from generating displacement along its axial direction when rotating. The frame thickness of the inner frame 8 ( Figure 4 the up and down dimensions of the inner frame 8 in Figure 4 ) is smaller than the width of the annular groove 13 (

[0032] the up and down dimensions of the annular groove 13 in Figure 4 ), and the frame thickness of the inner frame 8 is greater than the width of the opening of the annular groove 13. Figure 5 As Figure 5 shown, the outer frame 9 is formed by splicing two annular components. A clamping groove 15 is provided on one of the components, the opening of the clamping groove 15 faces the other component, a limiting block 16 is provided on the inner side wall of the clamping groove 15, and a clamping block 14 is provided on the other component. The shape of the clamping block 14 is as

[0033] shown. When the clamping block 14 is inserted into the clamping groove 15, the clamping block 14 is blocked by the limiting block 16 to prevent the clamping block 14 from disengaging from the clamping groove 15, thereby connecting the two components together. The two components can be spliced from both ends of the inner frame 8 towards the middle, and the inner frame 8 is embedded inside the outer frame 9. Figure 1 As

[0034] shown, the base 3 is horizontally arranged, and two vertical and oppositely arranged fixing rods 4 are connected above the base 3. A horizontally arranged rotating shaft 5 is connected to the fixing rods 4, and the rotating shaft 5 can rotate axially. The outer frame 9 and the inner frame 8 are arranged in the middle area between the two fixing rods 4, and the rotating shaft 5 is respectively connected to the left outer side wall and the right outer side wall of the outer frame 9. The rotating shaft 5 is specifically a damping rotating shaft. When the pitching angle of the camera body 7 needs to be adjusted, the outer frame 9 is swung back and forth to rotate along the rotating shaft 5. The outer frame 9 drives the inner frame 8 and the camera body 7 to rotate. When the camera body 7 rotates to an appropriate angle, the swinging of the outer frame 9 is stopped. Because the rotating shaft 5 is specifically a damping rotating shaft, the outer frame 9 stops swinging when no external force is applied, and finally the purpose of adjusting the pitching angle of the camera body 7 is achieved. Figure 1As shown in the figure, a clip 1 is connected to the lower part of the base 3. The clip 1 can be clamped on the upper border of the computer display screen to fix the base 3. A vertically arranged connecting shaft 2 is connected between the base 3 and the clip 1. The lower end of the connecting shaft 2 is fixedly connected to the clip 1, and the upper end of the connecting shaft 2 is inserted into the interior of the base 3 and rotatably connected to the base 3 through a rotary damper. When it is necessary to adjust the camera body 7 left and right, the base 3 can be rotated. The base 3 drives the outer frame 9, the inner frame 8 and the camera body 7 to rotate. When no rotational force is applied to the base 3, under the action of the rotary damper, the base 3 will not rotate.

[0035] As Figure 1 shown, the number of the connecting rods 6 is four. In the initial state, two of the connecting rods 6 are arranged vertically and two are arranged horizontally. Scale lines are provided on the front outer wall of the outer frame 9. The upper vertical connecting rod 6 points to the 0° of the scale. The scale encircles the outer frame 9 clockwise. By reading the scale pointed to by the upper connecting rod 6, the tilt angle of the camera body 7 can be known.

[0036] Although the present utility model has been described by using the above preferred embodiments, it is not intended to limit the protection scope of the present utility model. Any person skilled in the art, without departing from the spirit and scope of the present utility model, making various changes and modifications to the above embodiments still belongs to the protection scope of the present utility model.
