[0024] Example 1
[0025] like Figures 1 to 4The illustrated supplementary lighting structure for a surveillance camera includes a mounting surface 1. A camera 3 is mounted on the front side of the mounting surface 1 via a mounting bracket 2. A receiving platform 4 is mounted on the front side of the mounting surface 1. A first motor 5, a second motor 6, and a third motor 7 are provided on the front side of the receiving platform 4. Each of the first motor 5, second motor 6, and third motor 7 is equipped with a drive gear 8. A rotating drum 9 is located on the front side of the receiving platform 4 between the first motor 5, second motor 6, and third motor 7. A first reversing component 10 is rotatably mounted inside the rotating drum 9. A second reversing component 11 is rotatably mounted on the first reversing component 10. A third reversing component 12 is sleeved on the second reversing component 11. The first reversing component 10 includes: a first rotating shaft 101 rotatably mounted inside the rotating drum 9. A first gear 102 is mounted on the first rotating shaft 101. A first connecting rod 103 is located at the front of the first rotating shaft 101. A first adjusting rod 104 is hinged to the outside of the first connecting rod 103. The second reversing component 11 includes: a rotating shaft 101 located at the rear of the first connecting rod 103. The moving sleeve is provided with a second rotating shaft 111, a second gear 112 is provided on the rear side of the second rotating shaft 111, a second connecting rod 113 is provided on the front side of the second rotating shaft 111, and a second adjusting rod 114 is hinged to the outer side of the second connecting rod 113; the third reversing member 12 includes: a third gear 121 rotatably mounted on the second rotating shaft 111, a third connecting rod 122 provided on the outer side of the third gear 121, and a third adjusting rod 123 hinged to the outer side of the third connecting rod 122; a first adjusting rod 104, a second adjusting rod 114, and a third adjusting rod 123; The three adjusting rods 123 are on the same vertical plane; a supplementary light plate 13 is hinged between the first adjusting rod 104, the second adjusting rod 114, and the third adjusting rod 123; the receiving platform 4 is located below the mounting frame 2; a first limiting ring 14 is fixedly provided on the first rotating shaft 101, and the first limiting ring 14 is located between the first gear 102 and the second gear 112; a second limiting ring 15 is fixedly provided on the second rotating shaft 111, and the second limiting ring 15 is located between the second gear 112 and the third gear 121.
[0026] This invention places the supplementary lighting plate 13 below the camera 3 to provide an additional light source for the camera 3, while avoiding backlighting and enhancing the camera's shooting capability in low light conditions. This invention has at least three motors, each driving one of three commutator components, enabling the supplementary lighting plate 13 to rotate with high precision and flexibility, perfectly matching the camera's rotation for shooting. This allows for fixed-point rotation, ensuring an appropriate supplementary lighting distance between the supplementary lighting plate 13 and the camera, and working with the camera 3 to achieve accurate and high-quality capture of people or other objects. The three commutator components of this invention, through the design of limiting rings, allow each to rotate independently on the rotating drum 9, reducing the space and cost required for installation, optimizing the structural design, and improving operational flexibility and convenience.
[0027] Example 2
[0028] like Figures 1 to 4The illustrated supplementary lighting structure for a surveillance camera includes a mounting surface 1, which is a flat surface such as a wall or door frame used for mounting the surveillance camera. It is generally located at a high position. Given that it is inconvenient to clearly capture human images and backgrounds when the camera 3 is at a high position, this embodiment proposes to set a supplementary lighting plate 13 at a position below the camera 3 and drive the supplementary lighting plate 13 to rotate with high precision and flexibility. This, combined with the camera 3's accurate and high-quality capture of human images, enables more precise monitoring.
[0029] A camera 3 is mounted on the front side of mounting surface 1 via mounting bracket 2. Camera 3 can rotate nearly 360° to capture moving objects in the frame, such as people or vehicles, and display the video feed for user viewing. A supplementary lighting plate 13 is positioned below camera 3 to provide additional light, enhancing the camera's ability to shoot in low light conditions. This also prevents backlighting, ensuring light shines from below onto the monitored area for a clearer image.
[0030] Furthermore, a receiving platform 4 is installed on the front side of the mounting surface 1, below the mounting bracket 2. A first motor 5, a second motor 6, and a third motor 7 are provided on the front side of the receiving platform 4. The three motors are arranged in an equilateral triangle, but their heights are different and show a gradually increasing trend. A rotating cylinder 9 is located on the front side of the receiving platform 4, between the first motor 5, the second motor 6, and the third motor 7. The rotating cylinder 9 is hollow, and a first reversing member 10, a second reversing member 11, and a third reversing member 12 are rotatably mounted on its front side. These reversing members are driven by the first motor 5, the second motor 6, and the third motor 7, respectively. The fill light plate 13 is hinged between the ends of the first reversing member 10, the second reversing member 11, and the third reversing member 12. When one end of the reversing member rotates due to the influence of the motor, it will drive the fill light plate 13 to rotate. By adjusting the designated motor, the connected reversing member can be driven to adjust the angle of the fill light plate 13. At least three motors are required to drive the fill light plate 13 to perform omnidirectional angle adjustment, which is highly adaptable to the rotation and shooting of the camera. As the fill light plate 13 is restricted by three sides, it will rotate to a fixed point when the angle is adjusted. Specifically, the fixed point is the center of the circle when the fill light plate 13 is laid flat. In this way, it can be ensured that the fill light plate 13 and the camera are kept at an appropriate fill light distance without affecting the light source emitted by the fill light plate 13, so as to achieve the best fill light state.
[0031] A first reversing element 10 is rotatably mounted inside the rotating drum 9. A second reversing element 11 is rotatably mounted on the first reversing element 10, and a third reversing element 12 is sleeved on the second reversing element 11. At the same time, a first limiting ring 14 is fixedly mounted on the first reversing element 10, located between the first reversing element 10 and the second reversing element 11. A second limiting ring 15 is fixedly mounted on the second reversing element 11, located between the second reversing element 11 and the third reversing element 12. In this way, the first reversing element 10, the second reversing element 11, and the third reversing element 12 can all rotate independently on the rotating drum 9, reducing the space and cost required for installation and facilitating operation.
[0032] Example 3
[0033] like Figures 1 to 4 The illustrated supplementary lighting structure for a surveillance camera includes a first commutator 10, a second commutator 11, and a third commutator 12 rotatably mounted below the camera 3. These components are driven by a first motor 5, a second motor 6, and a third motor 7, respectively. A supplementary lighting plate 13 is hinged between the ends of the first commutator 10, the second commutator 11, and the third commutator 12. When one end of a commutator rotates due to the influence of a motor, it will cause the supplementary lighting plate 13 to rotate. By adjusting a specific motor, the connected commutator can be driven to adjust the angle of the supplementary lighting plate 13. At least three motors are required to drive the supplementary lighting plate 13 to perform omnidirectional angle adjustments, highly adaptable to the camera's rotation and shooting.
[0034] Specifically, the first reversing component 10 includes: a first rotating shaft 101 rotatably mounted inside the rotating drum 9, a first gear 102 mounted on the first rotating shaft 101, and a corresponding drive gear 8 connected to the shortest first motor 5 meshing with it; a first connecting rod 103 is mounted at the front of the first rotating shaft 101, and a first adjusting rod 104 is hinged to the outside of the first connecting rod 103, with the other end of the first adjusting rod 104 hinged to the fill light plate 13. Thus, the first motor 5 can drive the first gear 102 to rotate through the drive gear 8, and the rotation of the first gear 102 drives the first connecting rod 103 to rotate through the first rotating shaft 101, thereby driving the first adjusting rod 104 to rotate, achieving a 33% angle adjustment of the entire fill light plate 13.
[0035] The second reversing component 11 specifically includes: a second rotating shaft 111 movably sleeved on the first rotating shaft 101 at a position behind the first connecting rod 103, i.e., the second rotating shaft 111 is a hollow sleeve sleeved on the first rotating shaft 101, and the rotation of the two does not affect each other; a second gear 112 is also provided on the rear side of the second rotating shaft 111, and correspondingly, the drive gear 8 connected to the medium-height second motor 6 meshes with it; a second connecting rod 113 is provided at the front of the second rotating shaft 111, the second connecting rod 113 is located behind the first connecting rod 103, and a second adjusting rod 114 is hinged to the outside of the second connecting rod 113. The other end of the second adjusting rod 114 is hinged to the fill light plate 13. In this way, the drive second motor 6 can drive the second gear 112 to rotate through the drive gear 8. The rotation of the second gear 112 drives the second connecting rod 113 to rotate through the second rotating shaft 111, and then drives the second adjusting rod 114 to rotate. In cooperation with the first adjusting rod 104, a 66% angle adjustment of the entire fill light plate 13 is achieved.
[0036] The third reversing component 12 specifically includes: a third gear 121 rotatably mounted on the second rotating shaft 111 at a position behind the second limiting ring 15. The third gear 121 is sleeved on the second rotating shaft 111, and their rotations do not affect each other. Correspondingly, the drive gear 8 connected to the highest third motor 7 meshes with it. A third connecting rod 122 is provided in front of the third gear 121. The third connecting rod 122 is located behind the second connecting rod 113. A third adjusting rod 123 is hinged to the outside of the third connecting rod 122. The other end of the third adjusting rod 123 is hinged to the fill light plate 13. In this way, the drive third motor 7 can drive the third gear 121 to rotate through the drive gear 8. The rotation of the third gear 121 drives the third adjusting rod 123 to rotate through the third connecting rod 122. In cooperation with the first adjusting rod 104 and the second adjusting rod 114, the angle of the entire fill light plate 13 can be adjusted by 100%.
[0037] At this time, the rotating drum 9 consists of, from back to front, the first gear 102, the first limiting ring 14, the second gear 112, the second limiting ring 15, the third gear 121, the third connecting rod 122, the second connecting rod 113, and the first connecting rod 103. Meanwhile, the first adjusting rod 104, the second adjusting rod 114, and the third adjusting rod 123 are on the same vertical plane, which drives the fill light plate 13, which is hinged to the three, to remain perpendicular to the ground in the initial state. When adjusting the angle, the center of the circle in the vertical state is used as the fixed point to perform a 360° rotation adjustment. With the camera 3's accurate and high-quality capture of human images, more accurate monitoring can be achieved.
