Description

Technical Field

[0001] This application relates to the field of covers or caps for eliminating unwanted light from lenses, viewfinders, or focusing aids, and more specifically to a security camera with a light-shielding structure. Background Technology

[0002] Utility model patent document CN218378688U discloses a security camera with a shield assembly, including a housing. A connecting rod is fixedly installed inside the housing. One end of the connecting rod penetrates the housing and extends to the outside of the housing, where the camera body is fixedly installed. A tube is supported by a bearing on one side of the housing and outside the connecting rod. One side of the tube penetrates the housing and extends to the inside of the housing. A light-shielding plate is fixedly installed on the other side of the tube. A gear ring is fixedly installed on the surface of the tube and inside the housing. A motor is fixedly installed inside the housing, and a gear is fixedly installed on the output shaft of the motor. When the angle of the light-shielding plate needs to be adjusted, the output shaft of the motor drives the gear, thereby rotating the light-shielding plate to switch the direction of blocking strong light.

[0003] The aforementioned light-shielding plate can only rotate around the axis of the tube, and its blocking range is limited. It is difficult to cope with strong light incident from multiple directions and different angles (such as high and low angles). For example, it cannot effectively block direct light from both the bottom and the sides at the same time. Utility Model Content

The multiple light intensity sensors are mounted on the camera body and are circumferentially spaced apart. The multiple retractable light-shielding sheets are mounted on the camera body and are circumferentially spaced apart. Each retractable light-shielding sheet is located outside the corresponding light intensity sensor.

[0020] Reference Figure 1-2 This application proposes an embodiment of a security camera with a light-shielding structure, characterized in that it includes a camera body 10, a plurality of light intensity sensors 20, and a plurality of retractable light-shielding sheets 30 corresponding one-to-one with the plurality of light intensity sensors 20. The plurality of light intensity sensors 20 are mounted on the camera body 10 and are circumferentially spaced apart. The plurality of retractable light-shielding sheets 30 are mounted on the camera body 10 and are circumferentially spaced apart. Each retractable light-shielding sheet 30 is located outside the corresponding light intensity sensor 20. The light intensity sensors 20 and the retractable light-shielding sheets 30 are electrically connected to the camera body 10.

[0021] Multiple light intensity sensors 20 detect the light intensity at their respective locations and send the data to the camera body 10. When the light intensity at a location is greater than a preset range, the camera body 10 controls the retractable light-shielding sheet 30 corresponding to the light intensity sensor 20 to extend, thereby unfolding the retractable light-shielding sheet 30. The real-time light intensity is then obtained through the light intensity sensor 20 until it falls within the preset range, at which point the retractable light-shielding sheet 30 stops extending or retracting. When the light intensity at a location is less than the preset range, the camera body 10 controls the retractable light-shielding sheet 30 corresponding to the light intensity sensor 20 to shorten, and the real-time light intensity is then obtained through the light intensity sensor 20 until it falls within the preset range.

[0022] This application uses multiple light sensors to detect the light intensity of the camera body 10 in different directions, and controls the extension and retraction of the retractable light shield 30 based on the structure of the detected light intensity. Thus, the multiple retractable light shields 30 can achieve multi-directional light shielding of the camera body 10. In addition, the camera body 10 can also adjust the light shielding range by controlling the length of the retractable light shield 30 according to the light intensity, so as to cope with strong light irradiation from different angles.

[0023] Specifically, the retractable light shield 30 includes a telescopic drive component 31, a fixed rod 32, and at least two follower rods 33. The telescopic drive component 31 is mounted on the camera body 10. The fixed rod 32 is fixedly mounted on the telescopic end of the telescopic drive component 31. The follower rods 33 are slidably mounted on the telescopic end of the telescopic drive component 31. A flexible sunshade cloth 34 is installed between the fixed rod 32 and the follower rods 33, and between two adjacent follower rods 33.

[0024] When the telescopic drive member 31 extends, it drives the frontmost sunshade cloth 34 to move and unfold. After the sunshade cloth 34 between the fixed rod 32 and the follower rod 33 is fully unfolded, the telescopic drive member 31 continues to extend and drives the rear sunshade cloth 34 to unfold through the sunshade cloth 34 between the fixed rod 32 and the follower rod 33, thereby realizing the telescopic extension and retraction of the retractable light-shielding sheet 30.

[0025] Preferably, the device further includes two guide telescopic rods 40, which are mounted on the camera body 10 and located on both sides of the telescopic drive member 31. The fixing rod 32 is mounted on the guide telescopic rods 40. The guide telescopic rods 40 can improve the stability and structural strength of the retractable light shield 30.

[0026] Based on this, the follower rod 33 is also slidably mounted on the guide telescopic rod 40. Specifically, the follower rod 33 is provided with a slip ring 35, which is sleeved on the telescopic end of the telescopic drive member 31 or the guide telescopic rod 40, so that the follower rod 33 can slide on the telescopic end of the telescopic drive member 31 and the guide telescopic rod 40, so that when the retractable sunshade is extended or retracted, multiple follower rods 33 can slide to be close to or far away from each other on the telescopic end of the telescopic drive member 31 and the guide telescopic rod 40.

[0027] To achieve the above functions, a slip ring 35 can be installed on the follower rod 33. The slip ring 35 is sleeved on the telescopic end of the telescopic drive member 31 or the guide telescopic rod 40.

[0028] Preferably, the telescopic drive 31 is mounted on the side wall of the camera body 10, and the light intensity sensor 20 is mounted on the camera body 10 by a mounting component and located on the telescopic drive 31 on the side close to the housing, and the detection end of the light intensity sensor 20 is flush with the camera of the camera body 10.

[0029] The detection end of the light intensity sensor 20 is flush with the camera of the camera body 10 to accurately detect the light intensity at the camera and ensure that the light intensity after the retractable light shield 30 is extended or retracted can be detected.

[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
