Abstract
Description
Technical Field
[0001] This utility model relates to the field of camera equipment technology, specifically to a camera with dual cameras for monitoring. Background Technology
[0002] 360° rotating full-view cameras are widely used in security monitoring, but because the camera needs to physically rotate to cover a 360° range, its response speed is limited, resulting in momentary blind spots. For example, when multiple targets are moving quickly, the camera cannot simultaneously capture events from all directions.
[0003] Existing technologies typically extend coverage by adding fixed cameras, but this results in a significant increase in the overall height of the device, making it difficult to deploy in space-constrained scenarios and thus limiting its effectiveness. Utility Model Content
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a dual-camera monitoring camera, comprising a fixed camera assembly and a rotating camera assembly; The fixed camera assembly includes a base and a first camera fixed on the base; The rotating camera assembly includes a housing mounted on the base, a second camera fixed on the housing, and a first motor. The first motor is fixed to the bottom of the housing, and the first output shaft of the first motor is fixedly connected to the center of the base, so that the housing rotates relative to the base. The base includes a circular portion and a protrusion protruding from the circular portion. The first camera passes through the circular portion and the protrusion to protrude from the side wall of the base, and the projections of the first camera and the first motor along the exposure direction of the first camera have overlapping areas.

The fixed camera assembly includes a base and a first camera fixed on the base. The rotating camera assembly includes a housing on the circular part, a second camera fixed on the housing, and a first motor. The first output shaft of the first motor is fixedly connected to the center of the base, so that the housing rotates relative to the base, thereby offsetting the monitoring areas of the first camera and the second camera, which can expand the coverage area. In addition, the protrusion allows the first camera to overlap with the projection of the first motor along the exposed direction of the first camera, reducing the size in the height direction and reducing installation limitations.
[0006] Furthermore, the side of the protrusion away from the circular portion is a vertical plane, and the protruding surface of the first camera is parallel to the vertical plane.

[0008] Furthermore, the housing includes a rotating base, a rotating shell connected to the rotating base, and a second camera fixed on the rotating shell. The rotating base can rotate horizontally relative to the base, and the rotating shell can rotate vertically relative to the rotating base, so as to drive the second camera to rotate in both the horizontal and vertical directions.
[0009] Furthermore, there is a vertical limiting structure between the rotating seat and the base.
[0010] Furthermore, the rotating base has a first connecting arm and a second connecting arm protruding from both sides in a direction away from the base. The first connecting arm and the second connecting arm are clamped at both ends of the rotating shell, and the rotating shell can rotate in the vertical direction relative to the first connecting arm and the second connecting arm.
[0011] Furthermore, it also includes a second motor fixed to the rotating housing; The first connecting arm is provided with a circular groove, and the rotating shell is provided with a circular protrusion at the position opposite to the first connecting arm. The circular protrusion is inserted into the circular groove. The second connecting arm is provided with a connecting groove, and the second output shaft of the second motor passes through the side wall of the rotating shell and is fixedly connected to the connecting groove.
[0012] Furthermore, the rotating shell has a limiting protrusion on the side wall opposite to the second connecting arm, the second connecting arm has a limiting groove, the limiting groove has a limiting side wall, and the limiting protrusion abuts against the limiting side wall when the rotating shell rotates to a certain angle, so as to limit the rotation angle of the rotating shell.
[0013] Furthermore, the limiting groove is arc-shaped, and the limiting groove is also provided with an arc-shaped sidewall; when the rotating shell is rotating, the limiting protrusion only abuts against the arc-shaped sidewall, and the arc-shaped sidewall forms a rotating guide rail.
[0014] Furthermore, the arc-shaped sidewall is a semi-circular arc-shaped sidewall, and the limiting sidewall includes a first limiting sidewall and a second limiting sidewall arranged horizontally. The two sides of the arc-shaped sidewall are respectively connected to the side of the first limiting sidewall away from the connecting groove and the side of the second limiting sidewall away from the connecting groove.

The rotating camera assembly 20 includes a housing 21 on the circular part 111, a second camera 22 fixed on the housing 21, and a first motor 23. The first output shaft 231 of the first motor 23 is fixedly connected to the center of the base 11, so that the housing 21 can rotate relative to the base 11, thereby offsetting the monitoring area of the first camera 12 and the monitoring area of the second camera 22, thus expanding the coverage area. In addition, the protrusion 112 allows the first camera 12 to overlap with the projection of the first motor 23 along the exposed direction of the first camera 12, thereby reducing the size in the height direction and reducing installation limitations.
[0024] Preferably, refer to Figure 2 To further improve the overall integrity of the facade, the side of the protrusion 112 away from the circular part 111 is a vertical plane 1121, and the protruding surface 121 of the first camera 12 is parallel to the vertical plane 1121.

The rotating camera assembly 20 also includes a circuit board, which is fixed to the bottom of the base 11 or the housing 21. The first camera 12 and the circuit board are arranged to the left and right relative to the central axis L1, wherein the central axis L1 is the center of the rotating camera assembly 20 and is perpendicular to the exposure direction.
[0026] This embodiment cleverly utilizes the space between the base 11 and the housing 21 to place the circuit board by setting the first camera 12 and the circuit board to be on the left and right relative to the central axis L1, without adding any extra dimensions, thus further improving the space utilization of the device.
[0027] Preferably, refer to Figure 1The housing 21 includes a rotating base 211, a rotating shell 212 connected to the rotating base 211, and a second camera 22 fixed on the rotating shell 212. The rotating base 211 can rotate horizontally relative to the base 11, and the rotating shell 212 can rotate vertically relative to the rotating base 211, so as to drive the second camera 22 to rotate in both horizontal and vertical directions.
