Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0026] Please see Figures 1 to 4 This application provides an angle adjustment mechanism 60 for a dome camera 100. The dome camera 100 includes a camera 10, a ball head housing 20, a rotating bracket 30, a fixture 40, a base shell 50, and the angle adjustment mechanism 60. The ball head housing 20 includes a first ball head housing 21 and a second ball head housing 22, with the camera 10 fixedly mounted on the first ball head housing 21. The ball head housing 20 is mounted on the rotating bracket 30. The rotating bracket 30 is mounted on the fixture 40. The fixture 40 is fixedly mounted on the base shell 50. The angle adjustment mechanism 60 is used to adjust the first ball head housing 21 to rotate horizontally relative to the second ball head housing 22, and the rotating bracket 30 to rotate horizontally relative to the fixture 40 and / or the ball head housing 20 to rotate vertically relative to the rotating bracket 30.

[0027] In the angle adjustment mechanism 60 of the dome camera 100 according to this embodiment, the camera 10 is fixedly mounted on the first dome housing 21. The angle adjustment mechanism 60 is used to adjust the first dome housing 21 to rotate horizontally relative to the second dome housing 22, and the rotating bracket 30 to rotate horizontally relative to the fixture 40 and / or the dome housing 20 to rotate vertically relative to the rotating bracket 30. Thus, the camera 10 can rotate in the horizontal direction and / or the vertical direction, giving the dome camera 100 a wider shooting range.

[0028] The ball-head housing 20 includes a first ball-head housing 21 and a second ball-head housing 22. The first ball-head housing 21 is hemispherical in shape, and the second ball-head housing 22 is cylindrical in shape. The first ball-head housing 21 and the second ball-head housing 22 are assembled to form a complete ball-head housing 20. The camera 10 is fixedly mounted on the first ball-head housing 21, for example, by screws or threads. When the first ball-head housing 21 rotates horizontally relative to the second ball-head housing 22, it can cause the camera 10 to rotate horizontally relative to the second ball-head housing 22.

[0029] The ball head housing 20 is mounted on the rotating bracket 30, the rotating bracket 30 is mounted on the fixture 40, and the fixture 40 is fixedly mounted on the bottom shell 50. For example, the fixture 40 can be fixedly mounted on the bottom shell 50 with screws. When the rotating bracket 30 rotates horizontally relative to the fixture 40, it can drive the ball head housing 20 to rotate horizontally, thereby driving the camera 10 on the first ball head housing 21 to rotate horizontally relative to the fixture 40.

[0030] The horizontal rotation of the first ball-head housing 21 relative to the second ball-head housing 22 and the horizontal rotation of the rotating bracket 30 relative to the fixture 40 allow the camera 10 to rotate horizontally relative to the bottom housing 50 within a large angle range, even up to 360°. The axis of this horizontal rotation can be the central axis of the first ball-head housing 21. Figure 4 The dashed line O1 in the diagram represents this.

[0031] When the ball head housing 20 rotates vertically relative to the rotating bracket 30, it can cause the camera 10 on the first ball head housing 21 to rotate vertically relative to the rotating bracket 30 (i.e., pitch motion). Thus, in the vertical direction, the camera 10 can rotate a certain angle relative to the bottom housing 50. The axis of the vertical rotation is perpendicular to the axis of the horizontal rotation and can be the radial direction of the second ball head housing 22. Figure 4 The dashed line O2 in the diagram represents this.

[0032] By configuring an angle adjustment mechanism 60 in the dome camera 100, the first ball head housing 21 can rotate horizontally relative to the second ball head housing 22, and the rotating bracket 30 can rotate horizontally relative to the fixture 40; alternatively, the ball head housing 20 can rotate vertically relative to the rotating bracket 30; or, the first ball head housing 21 can rotate horizontally relative to the second ball head housing 22, and the rotating bracket 30 can rotate horizontally relative to the fixture 40, while simultaneously rotating vertically relative to the rotating bracket 30. Thus, the camera 10 can rotate in the horizontal direction and / or the vertical direction, allowing the dome camera 100 to have a wide shooting range.

[0033] Please see Figure 3 and Figure 5In some embodiments, the dome camera 100 is a binocular dome camera. The camera 10 includes two camera components 11, each including a lens 111, a lens ring 112, a light source assembly 113, and a lens bracket 114. The first dome head housing 21 includes a housing body 211 and a housing decorative piece 212. The housing decorative piece 212 is fixedly disposed on the housing body 211. The lens 111 and the light source assembly 113 are fixedly disposed on the lens bracket 114, and the lens bracket 114 is fixedly disposed on the housing body 211. The lens ring 112 is fixedly disposed on the housing decorative piece 212 and aligned with the lens 111.

[0034] Specifically, the dome camera 100 is a binocular dome camera, and the camera 10 includes two camera components 11, which are symmetrically arranged about the central axis O1 of the first dome head housing 21. Each camera component 11 includes a lens 111, a lens ring 112, a light source assembly 113, and a lens bracket 114. Each camera component 11 contains one lens 111, one lens ring 112, one light source assembly 113, and one lens bracket 114. The first dome head housing 21 includes a housing body 211 and a housing decorative piece 212. The housing decorative piece 212 covers the housing body 211 and is adapted to the shape of the housing body 211.

[0035] The lens 111 and the light source assembly 113 can be fixedly mounted to the lens bracket 114 by screws, and the lens bracket 114 is then fixedly mounted to the housing body 211 by screws. In this way, the lens 111 and the light source assembly 113 can be fixedly mounted to the housing body 211 along with the lens bracket 114.

[0036] The lens ring 112 can be fixed to the housing decorative piece 212 with screws and aligned with the lens 111. That is to say, the optical axis of the lens ring 112 coincides with the optical axis of the lens 111. The housing decorative piece 212 is then fixed to the housing body 211 with screws, so the lens ring 112 can be fixed to the housing body 211 along with the housing decorative piece 212.

[0037] Please see Figure 2 The dome camera 100 may also include a dome housing 70, which has good sealing performance, keeping the camera 10 clear and preventing it from being affected or damaged by the external environment due to exposure. In some cases, the dome housing 70 may refract light. The refracted light entering the lens 111 can lead to poor image quality, such as bright spots appearing in the image. The lens ring 112 can block the light refracted by the dome housing 70, ensuring the image quality of the lens 111.

[0038] Please see Figure 3The light source assembly 113 may include a lamp panel 1131 and a lens unit 1132. The lamp panel 1131 may be a dual-color lamp panel for white light and infrared light, and may switch between emitting white light or infrared light. The lens unit 1132 is disposed on the lamp panel 1131, and the lens unit 1132 includes a white light lens and an infrared light lens, and the lens unit 1132 may serve to uniformly emit light.

[0039] The camera assembly 11 may also include a light guide column 115, which is used to detect ambient light. Based on the detection results, the light panel 1131 can switch between different emitted lights in different environments to capture clear images. It is understood that infrared light is suitable for shooting in normal lighting environments and for shooting in darker environments. When normal ambient light is detected, such as when the dome camera 100 is in a daytime environment, the light panel 1131 is controlled to emit white light for shooting. When the ambient light is detected to be dim, such as when the dome camera 100 is in a nighttime environment, the light panel 1131 is controlled to emit infrared light for shooting.

[0040] Please see Figure 3 In some embodiments, the angle adjustment mechanism 60 includes a first latch 61. The first latch 61 is formed in one of the first ball head housing 21 and the second ball head housing 22, and has a gap with the other ball head housing 21 and the second ball head housing 22 to allow the first ball head housing 21 to rotate horizontally relative to the second ball head housing 22.

[0041] Specifically, the first ball-end housing 21 and the second ball-end housing 22 can be connected by a first latch 61. The first latch 61 can be formed in either the first ball-end housing 21 or the second ball-end housing 22. For example, if the first latch 61 is formed in the first ball-end housing 21, then when the first ball-end housing 21 and the second ball-end housing 22 are connected, there is a radial gap between the first latch 61 and the second ball-end housing 22. The first latch 61 can also be formed in the second ball-end housing 22 (e.g., ...). Figure 3 As shown), when the first ball head housing 21 and the second ball head housing 22 are connected, there is a radial gap between the first latch 61 and the first ball head housing 21. The number of first latches 61 is not limited; for example, the number of first latches 61 can be 1, 2, or 3 (e.g., ...). Figure 3 (as shown) or more.

[0042] by Figure 3For example, the gap between the first latch 61 and the second ball-head housing 22 allows the first latch 61 to rotate horizontally relative to the second ball-head housing 22, thereby allowing the first ball-head housing 21 to rotate horizontally relative to the second ball-head housing 22. After the first ball-head housing 21 rotates horizontally relative to the second ball-head housing 22 at a certain angle, friction exists between the first ball-head housing 21 and the second ball-head housing 22 under normal conditions. This ensures that the connection between the first ball-head housing 21 and the second ball-head housing 22 will not loosen arbitrarily without expected intervention, thus preventing a change in the angle of the camera 10. Expected intervention can occur through manual rotation or electric control.

[0043] Please see Figure 6 In some embodiments, the angle adjustment mechanism 60 further includes a first limiting protrusion 62 and a first limiting bone 63. The first limiting protrusion 62 is formed in one of the first ball head housing 21 and the second ball head housing 22, and the first limiting bone 63 is formed in the other of the first ball head housing 21 and the second ball head housing 22. The first limiting protrusion 62 and the first limiting bone 63 cooperate to limit the horizontal rotation of the first ball head housing 21 relative to the second ball head housing 22 by 0°-90°.

[0044] The first limiting protrusion 62 is formed in either the first ball-head housing 21 or the second ball-head housing 22, and the first limiting bone 63 is formed in the other ball-head housing 21 or the second ball-head housing 22. For example, when the first limiting protrusion 62 is formed in the first ball-head housing 21, the first limiting bone 63 is formed in the second ball-head housing 22; when the first limiting protrusion 62 is formed in the second ball-head housing 22, the first limiting bone 63 is formed in the first ball-head housing 21. There can be two first limiting bones 63, and the two first limiting bones 63 are 90° apart circumferentially along the first ball-head housing 21 or the second ball-head housing 22.

[0045] like Figure 6As shown, taking the first limiting protrusion 62 formed on the second ball-head housing 22 and the first limiting bone 63 formed on the first ball-head housing 21 as an example, when the first ball-head housing 21 and the second ball-head housing 22 are connected, the first limiting protrusion 62 is located between the two first limiting bones 63, and along the height direction of the ball-head housing 20, the height of the first limiting protrusion 62 and the first limiting bone 63 at least partially overlap. The first limiting protrusion 62 can be formed on the first buckle 61, or it can be formed at other positions at the same height on the second ball-head housing 22. When the first ball-head housing 21 rotates horizontally relative to the second ball-head housing 22, the first limiting protrusion 62 rotates horizontally between the two first limiting bones 63 along with the second ball-head housing 22. When the first limiting protrusion 62 rotates to the position of the first limiting bone 63, since the heights of the first limiting protrusion 62 and the first limiting bone 63 at least partially overlap, the first limiting bone 63 abuts against the first limiting protrusion 62 to restrict the rotation of the first limiting protrusion 62, thereby restricting the horizontal rotation of the first ball-head housing 21 relative to the second ball-head housing 22. The angle range in which the first ball-head housing 21 can rotate horizontally relative to the second ball-head housing 22 is 0°-90°.

[0046] In practical applications, the dome camera 100 can be fixed indoors or outdoors using bolts or other parts. Specifically, it can be fixed to the roof (i.e., suspended) or fixed to a wall side (i.e., wall-mounted). When suspended or wall-mounted, the dome camera 100 is in different spatial positions, and the direction of the image captured by the camera 10 is different. Therefore, when the installation method changes, the camera 10 needs to be rotated to ensure that the image remains upright. Research has found that when changing from suspended to wall-mounted, rotating the first ball head housing 21 horizontally relative to the second ball head housing 22 by 90° can keep the image upright. Therefore, in this embodiment, the angle range of horizontal rotation of the first ball head housing 21 relative to the second ball head housing 22 is limited to 0°-90°. Of course, in other embodiments, the angle range of horizontal rotation of the first ball head housing 21 relative to the second ball head housing 22 can be set to a larger range, for example, 0°-100°, 0°-110°, or 0°-120°, etc.

[0047] Please see Figure 2 , Figure 4 and Figure 7 In some embodiments, the angle adjustment mechanism 60 includes a connector 64. The ball head housing 20 is connected to the rotating support 30 via the connector 64. A gap exists between the connector 64 and the ball head housing 20 to allow the ball head housing 20 to rotate vertically relative to the rotating support 30.

[0048] Specifically, the connector 64 can be a screw or other parts with a connecting function. The connector 64 is used to connect the ball head housing 20 and the rotating bracket 30. There is a gap between the connector 64 and the ball head housing 20, which provides enough space for the ball head housing 20 to rotate perpendicularly relative to the rotating bracket 30.

[0049] Please see Figure 7 In some embodiments, the angle adjustment mechanism 60 further includes a limiting groove 65 and a second limiting rib 66. The limiting groove 65 is formed in one of the ball head housing 20 and the rotating bracket 30, and the second limiting rib 66 is formed in the other of the ball head housing 20 and the rotating bracket 30. The second limiting rib 66 is used to slide within the limiting groove 65 to limit the vertical rotation of the ball head housing 20 relative to the rotating bracket 30 by 0°-110°.

[0050] Specifically, the limiting groove 65 can be formed in the ball head shell 20, in which case the second limiting bone position 66 is formed in the rotating bracket 30. Alternatively, the limiting groove 65 can be formed in the rotating bracket 30, in which case the second limiting bone position is formed in the ball head shell 20. There can be two limiting grooves 65 and two limiting bone positions 66. The two limiting grooves 65 are located at opposite ends of one of the ball head shell 20 and the rotating bracket 30, and the two second limiting bone positions 66 are located at opposite ends of the other of the ball head shell 20 and the rotating bracket 30.

[0051] The limiting groove 65 can be set to an arc shape, and the second limiting bone position 66 can slide along the arc within the limiting groove 65, so that the ball head can rotate perpendicularly relative to the rotating bracket 30, and the axis of rotation is... Figure 4 The dashed line O2 can be the line connecting the centers of the arcs containing the two limiting grooves 65. By limiting the length of the limiting grooves 65, the angular range of vertical rotation of the ball head housing 20 relative to the rotating bracket 30 can be limited. The angular range can be set according to actual needs to give the dome camera 100 a wider shooting range. For example, research has shown that an angular range of 0°-110° vertical rotation of the ball head housing 20 relative to the rotating bracket 30 can meet the shooting requirements in practical applications; therefore, the angular range of vertical rotation of the ball head housing 20 relative to the rotating bracket 30 can be limited to 0°-110° by limiting the length of the limiting grooves 65.

[0052] Please see Figure 7 In some embodiments, the angle adjustment mechanism 60 includes a second latch 67 formed in one of the rotating bracket 30 and the retainer 40 and having a gap with the other of the rotating bracket 30 and the retainer 40 to allow the rotating bracket 30 to rotate horizontally relative to the retainer 40.

[0053] Specifically, the rotating bracket 30 and the retainer 40 can be connected by a second snap-fit ​​67. The second snap-fit ​​67 can be formed in either the rotating bracket 30 or the retainer 40; for example, the second snap-fit ​​67 can be formed in the rotating bracket 30 (e.g.,...). Figure 7 As shown), the second latch 67 has a radial gap with the retainer 40. The second latch 67 may also be formed on the retainer 40, and a radial gap may exist between the second latch 67 and the rotating bracket 30. The number of second latches 67 is not limited; for example, the number of second latches 67 can be one, two, or three (e.g., ...). Figure 2 (as shown) or more.

[0054] by Figure 7 For example, the gap between the second latch 67 and the retainer 40 allows the second latch 67 to rotate horizontally relative to the retainer 40, thereby allowing the rotating bracket 30 to rotate horizontally relative to the retainer 40. After the rotating bracket 30 rotates horizontally relative to the retainer 40 at a certain angle, friction exists between the rotating bracket 30 and the retainer 40 in its natural state. This ensures that the connection between the rotating bracket 30 and the retainer 40 will not loosen arbitrarily without expected intervention, thus preventing changes in the angle. Expected intervention can occur through manual rotation or electric control.

[0055] Please see Figure 4 and Figure 7 In some embodiments, the angle adjustment mechanism 60 further includes a second limiting protrusion 68 and a third limiting bone position 69. The second limiting protrusion 68 is formed in one of the rotating bracket 30 and the fixator 40, and the third limiting bone position 69 is formed in the other of the rotating bracket 30 and the fixator 40. The second limiting protrusion 68 and the third limiting bone position 69 cooperate to limit the horizontal rotation of the rotating bracket 30 relative to the fixator 40 from 0° to 350°.

[0056] The second limiting protrusion 68 is formed in either the rotating bracket 30 or the fixator 40, and the third limiting bone position 69 is formed in the other of the rotating bracket 30 and the fixator 40. For example, when the second limiting protrusion 68 is formed in the rotating bracket 30, the third limiting bone position 69 is formed in the fixator 40; when the second limiting protrusion 68 is formed in the fixator 40, the third limiting bone position 69 is formed in the rotating bracket 30. There can be one third limiting bone position 69, which can be located at any position circumferentially on either the rotating bracket 30 or the fixator 40.

[0057] like Figure 7 As shown, taking the second limiting protrusion 68 formed on the rotating bracket 30 and the third limiting bone position 69 formed on the fixator 40 as an example, when the rotating bracket 30 is connected to the fixator 40 (e.g. Figure 4As shown, along the height direction of the ball head housing 20, the heights of the second limiting protrusion 68 and the third limiting bone position 69 at least partially overlap. When the rotating bracket 30 rotates horizontally relative to the fixator 40, the second limiting protrusion 68 rotates horizontally with the fixator 40. When the second limiting protrusion 68 rotates to the position of the third limiting bone position 69, since the heights of the second limiting protrusion 68 and the third limiting bone position 69 at least partially overlap, the third limiting bone position 69 can abut against the second limiting protrusion 68 to restrict the rotation of the second limiting protrusion 68, thereby restricting the horizontal rotation of the rotating bracket 30 relative to the fixator 40. The rotating bracket 30 can rotate horizontally relative to the fixator 40 in the range of 0°-350°.

[0058] It is understandable that the third limiting bone position 69 has a certain width, restricting the horizontal rotation of the rotating bracket 30 relative to the fixator 40 from reaching 360°. However, the horizontal rotation angle range of the rotating bracket 30 relative to the fixator 40 is 0°-350°. Combined with the aforementioned horizontal rotation angle range of the first ball head housing 21 relative to the second ball head housing 22 (0°-90°), the horizontal rotation angle range of the first ball head housing 21 relative to the fixator 40 is 0°-360°. Thus, the camera 10 can rotate 0°-360° horizontally, allowing the dome camera 100 to have a wide shooting range.

[0059] Please see Figure 2 In some embodiments, the dome camera 100 further includes a damping element 80 disposed between the rotating bracket 30 and the fixture 40.

[0060] Specifically, the damping element 80 can be made of silicone. The damping element 80 is positioned between the rotating bracket 30 and the fixing device 40. When the rotating bracket 30 rotates horizontally relative to the fixing device 40, the damping element 80 increases damping, adjusting the rotation feel of the rotating bracket 30. There is no limitation on the number of damping elements 80; for example, the number of damping elements 80 can be one, two, or three (e.g., ...). Figure 2 (as shown) or more.

[0061] Please see Figure 8 In some embodiments, the dome camera 100 also includes a motherboard 90 and a fixing member 91, with the fixing member 91 fixing the fixing member 40 and the motherboard 90 to the bottom shell 50.

[0062] Specifically, the motherboard 90 can integrate multiple functional components to control the operation of the dome camera 100. The fixture 40 and the motherboard 90 can be fixedly mounted to the base shell 50 by a fastener 91, which can be a screw or other parts that can achieve a fixed connection. There is no limit to the number of fasteners 91; for example, the number of fasteners 91 can be one, two, three, or more.

[0063] Please see Figure 3 and Figure 9 In some embodiments, the dome camera 100 is a binocular dome camera, and the camera 10 includes two camera components 11, each camera component 11 including a lens 111, the field of view of the lens 111 is 100°-120°, and the angle between the central axis of the lens 111 and the central axis of the dome housing 20 is 39°-43°.

[0064] Specifically, the field of view of each lens 111 is 100°-120°, and the central axis of the lens 111 (e.g., Figure 9 (Dash lines O3 and O4) and the central axis of the ball head housing 20 (e.g.) Figure 9 The angle between the dashed lines O1 and O1 ranges from 39° to 43°. For example... Figure 9 For example, each lens 111 has a field of view of 105°, and the angle between the central axis of lens 111 and the central axis of the ball head housing 20 is 41°. The images captured by the two lenses 111 can be stitched and cropped by software to obtain an image with a field of view greater than 180°. Compared to a monocular camera, camera 10 has a larger field of view.

[0065] In related technologies, fisheye lenses are used to capture images. Although the field of view of a single fisheye lens exceeds 180°, the resulting images suffer from severe distortion and low image quality. In contrast, the embodiment of this application uses two lenses 111 for shooting, which expands the field of view while maintaining image quality.

[0066] In summary, in the angle adjustment mechanism 60 of the dome camera 100 according to the embodiments of this application, the camera 10 is fixedly mounted on the first dome housing 21. The angle adjustment mechanism 60 is used to adjust the first dome housing 21 to rotate horizontally relative to the second dome housing 22, and the rotating bracket 30 to rotate horizontally relative to the fixture 40 and / or the dome housing 20 to rotate vertically relative to the rotating bracket 30. Thus, the camera 10 can rotate in the horizontal direction and / or the vertical direction, giving the dome camera 100 a wider shooting range.
