Description

[0001] This application is a divisional application of the patent application filed on July 25, 2024, with application number 2024217890724 and patent title "Camera Equipment and Rotating Assembly". Technical Field

[0002] This application relates to the field of electronic equipment technology, and in particular to a camera device. Background Technology

[0003] A camera is a device that captures images and videos, and it is widely used in fields such as security monitoring and video communication. The field of view and shooting angle of a camera are important performance indicators that directly affect the shooting effect.

[0004] Typically, video cameras have a fixed field of view, which is related to the size and resolution of the image sensor. If the scene to be observed is large, the camera may not be able to cover the entire area, easily resulting in blind spots. The shooting angle of a video camera is determined by its installation position and lens direction. If the camera is fixedly installed, it can only capture objects within a certain angle in front of the lens. To improve the shooting range of a video camera, a larger field of view and shooting angle are better.

[0005] However, current camera equipment is limited by factors such as image sensor size, imaging principle, and installation height, resulting in a small field of view and shooting angle, making it impossible to achieve comprehensive observation of large scenes. Utility Model Content

[0006] The purpose of this application is to provide a camera device that can achieve comprehensive observation of a large scene.

[0007] To achieve the above objectives, this application provides a rotating assembly having a first axis and a second axis, wherein the first axis is different from the second axis, and the rotating assembly is connected to a first camera so that the first camera can rotate around the first axis and the second axis;

[0008] The rotating assembly includes a first rotating frame, which has a base plate, a first arc-shaped arm and a second arc-shaped arm. The base plate extends in a direction parallel to the second axis, and the first arc-shaped arm and the second arc-shaped arm are respectively connected to both sides of the base plate and extend in a direction parallel to the first axis on both sides of the base plate.

[0009] The first arc-shaped arm has a first rotating shaft at its end, and the second arc-shaped arm has a second rotating shaft at its end. The first rotating shaft and the second rotating shaft are arranged opposite to each other. The center line of the first rotating shaft coincides with the center line of the second rotating shaft, and the center line of the first rotating shaft is distributed along the second axis.

[0010] To achieve the above objectives, this application also provides a camera device, comprising:

[0011] The housing module has a first facet and a second facet, the first facet is located above the second facet and the first facet and the second facet are set at an angle, the first facet is provided with a first observation hole and the second facet is provided with a second observation hole;

[0012] A first camera module is located inside the housing module and is rotatably nested in the first observation hole;

[0013] The second camera module is located inside the housing module and is rotatably nested in the second observation hole;

[0014] A rotating component is provided for driving a first camera in the first camera module to rotate around the first axis and the second axis.

[0015] Therefore, the technical solution provided in this application includes a camera device housing with two angled observation holes, and two camera modules, a first camera module and a second camera module, are installed inside the housing. These two camera modules are rotatably nested within the observation holes. This allows the first and second camera modules to have different shooting angles, thereby expanding the overall observation range of the camera device. Furthermore, the first camera module is equipped with a rotating component, which allows for horizontal and vertical rotation to further expand the viewing angle. The second camera module is equipped with a second rotating component, which also allows for horizontal and vertical rotation to expand the viewing angle. The rotating components are independent of each other and do not interfere with each other during rotation, allowing the first and second camera modules to rotate independently. In the solution of this application, since the camera device has two independently rotatable camera modules, different types of lenses can be selected for the two camera modules according to actual needs. For example, the first camera module can be equipped with a panoramic lens, and the second camera module can be equipped with a close-up lens. Combined with the angled installation method, the blind spots of the camera device can be minimized to achieve comprehensive observation of a large scene. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings. Terms used in this application to indicate spatial relative positions, such as "above," "over," "below," "under," "first end," "second end," "one end," and "other end," are for ease of explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than those shown in the figures. For example, if the device in the figures is flipped, a unit described as being "below" or "under" other units or features would be located "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein will be interpreted accordingly.

[0035] Furthermore, the terms "installation," "setup," "equipped with," "connection," "sliding connection," "fixed," and "sleeve connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] A camera is a device that captures images and videos, and it has wide applications in fields such as security monitoring and video communication. The field of view and shooting angle of a camera are important performance indicators, directly affecting the range of scenes the camera can capture.

[0037] The field of view (FOP) of a camera refers to the entire spatial area of ​​the scene that the camera lens can capture. Most cameras have a fixed FOP after installation, and its size is related to the size and resolution of the image sensor. If the scene to be observed is larger than the camera lens's FOP, the camera lens cannot capture the entire scene at once, potentially resulting in some areas not covered by the camera, creating blind spots. The shooting angle of a camera refers to the range of angles that the camera lens can cover, usually measured in angles, such as horizontal, vertical, or diagonal field of view. The shooting angle of a camera is determined by its installation location and lens orientation. If the camera is fixedly installed, it can only capture objects within a certain angle in front of the lens.

[0038] To maximize the field of view and shooting angle of video equipment, a wider field of view is always better. However, current video equipment is limited by factors such as image sensor size, imaging principles, and installation height, resulting in relatively small fields of view and shooting angles. Due to these limitations, video equipment may not be able to provide a comprehensive view of large spaces such as conference rooms, shopping malls, or outdoor locations.

[0039] Therefore, how to improve the structure of camera equipment so that it can comprehensively observe larger scenes has become an urgent issue to be addressed in this field.

[0040] The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the embodiments described in this application are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0041] This application provides a camera device; please refer to [other sources]. Figures 1 to 16As shown, in one feasible implementation, the camera device includes at least a housing module 1, a first camera module 2, and a second camera module 3. The housing module 1 mainly consists of a front cover 11 and a rear cover 12. When assembled, the front cover 11 and the rear cover 12 form an accommodating space, in which the first camera module 2 and the second camera module 3 are placed; that is, the first camera module 2 and the second camera module 3 are located inside the housing module 1. The housing module 1 not only protects the first camera module 2 and the second camera module 3 from the intrusion of dust, rain, fog, and other impurities, but also provides stable physical support for the first camera module 2 and the second camera module 3, ensuring their stability after installation.

[0042] The surface of the housing module 1 has two planes, denoted as a first facet 13 and a second facet 14. Specifically, the first facet 13 and the second facet 14 can be disposed on the front cover 11, and arranged in a manner consistent with... Figure 1 The shown viewpoint is for reference only. A first facet 13 is positioned above a second facet 14. A first observation hole 131 is provided on the first facet 13, and a second observation hole 141 is provided on the second facet 14. A first camera module 2 is nested within the first observation hole 131 to capture images through it. The first camera module 2 is rotatably nested within the first observation hole 131, meaning it can rotate within the first observation hole 131, thereby expanding its shooting angle. A second camera module 3 is nested within the second observation hole 141 to capture images through it. The second camera module 3 is also rotatably nested within the second observation hole 141, meaning it can rotate within the second observation hole 141, thereby expanding its shooting angle.

[0043] In this embodiment, the first facet 13 and the second facet 14 are angled, meaning they are not parallel but tilted at a certain angle. Consequently, the first observation hole 131 and the second observation hole 141 are also angled. Since the first camera module 2 and the second camera module 3 are nested within the first observation hole 131 and the second observation hole 141 respectively, they will have different lens mounting angles within the housing module 1. This allows the first camera module 2 and the second camera module 3 to capture images from different shooting angles, covering each other's blind spots and thus improving the observation range of the entire scene.

[0044] For example, assuming the camera device is installed on a vertical wall, the first facet 13 is perpendicular to the ground. When the first facet 13 and the second facet 14 are on the same plane, the blind spot of the second camera module 3, located below the first camera module 2, is approximately... Figure 5aThe shadowed area in the image. When the first facet 13 and the second facet 14 are set at an angle, the blind spot of the second camera module 3, located below the first camera module 2, is approximately... Figure 5b The shadowed area in the image. Clearly, when the first facet 13 and the second facet 14 are set at an angle, the blind spot of the second camera module 3 is smaller. For example... Figure 5c As shown, the blind spot of the second camera module 3 can be calculated using the following formula: M=H*tg(θ), θ=90°-α-β / 2, where α is the angle between the second facet 14 and the first facet 13, β is the vertical field of view of the second camera module 3, H is the installation height of the second camera module 3, and M is the projection distance of the blind spot of the second camera module 3 onto the ground.

[0045] Furthermore, the first camera module 2 includes a first camera 21 and a rotating component 22. The first camera 21 is used to capture images, and the rotating component 22 is connected to the first camera 21 and is used to drive the first camera 21 to rotate inside the housing module 1. In this embodiment, the rotating component 22 has two different rotation axes, denoted as the first axis L1 and the second axis L2, respectively. The first camera 21 can rotate around the first axis L1 or around the second axis L2.

[0046] Furthermore, the second camera module 3 includes a second camera 31 and a second rotating component 32. The second camera 31 is used to capture images, and the second rotating component 32 is connected to the second camera 31 and is used to drive the second camera 31 to rotate inside the housing module 1. In this embodiment, the second rotating component 32 has two different rotation axes, denoted as the third axis L3 and the fourth axis L4, respectively. The second camera 31 can rotate around the third axis L3 or around the fourth axis L4.

[0047] It should be noted that the rotating component 22 and the second rotating component 32 are two independent rotating mechanisms, and they will not interfere with each other during rotation. When the rotating component 22 rotates, the second rotating component 32 may or may not rotate. Correspondingly, when the second rotating component 32 rotates, the rotating component 22 may or may not rotate.

[0048] In one feasible implementation, the first camera module 2 further includes a spherical shell 23, which has a first viewing window 231, and the first camera 21 is nested in the first viewing window 231. The diameter of the spherical shell 23 is adapted to the diameter of the first observation hole 131, so that the spherical shell 23 is rotatably nested in the first observation hole 131. The first observation hole 131 and the first viewing window 231 provide an observation channel for the first camera 21, so that the lens in the first camera 21 can capture images through the first observation hole 131 and the first viewing window 231. At the same time, in order to avoid the front cover 11 from obstructing the viewing angle of the first viewing window 231, when the spherical shell 23 is nested in the first observation hole 131, the first viewing window 231 on the spherical shell 23 must be exposed from the first observation hole 131.

[0049] In this embodiment, the spherical shell 23 is connected to the first camera 21 through the nesting action of the first viewing window 231. After the first camera 21 is nested in the first viewing window 231, the relative positional relationship between the spherical shell 23 and the first camera 21 will be fixed, and the positional change of the spherical shell 23 will be driven by the first camera 21. When the first camera 21 rotates, the spherical shell 23 will rotate synchronously with the first camera 21. Since the spherical shell 23 is rotatably nested in the first observation hole 131, when the spherical shell 23 rotates with the first camera 21, the spherical shell 23 can rotate in the first observation hole 131, and the front cover 11 will not hinder the rotation of the spherical shell 23.

[0050] It should be noted that when constructing the spherical shell 23, a circular notch a can be made on the surface of the spherical structure to form a first viewing window 231, and a circular notch b can be made on the side opposite to the first viewing window 231. The center of the circular notch a, the center of the spherical structure, and the center of the circular notch b are on a straight line. The first camera 21 can enter the interior of the spherical shell 23 through the circular notch b, and then the lens can be nested in the circular notch a. There is a relationship between the diameter of the first observation hole 131 and the rotation range of the first viewing window 231. The diameter of the first observation hole 131 must ensure that the first observation hole 131 does not obstruct the viewing angle of the first viewing window 231 throughout its entire rotation range.

[0051] In one feasible implementation, the rotating assembly 22 includes a first rotating member and a second rotating member. The rotating assembly 22 is connected to the front cover 11 via the first rotating member, and the first camera 21 is connected to the main structure of the rotating assembly 22 via the second rotating member. The front cover 11 provides structural support for the rotating assembly 22, and the rotating assembly 22 provides structural support for the first camera 21. How the rotating assembly 22 is connected to the front cover 11 via the first rotating member, and how the first camera 21 is connected to the main structure of the rotating assembly 22 via the second rotating member, will be explained in detail later.

[0052] In this embodiment, the first rotating assembly has a rotation axis, and the components connected to it can rotate around this axis. The second rotating assembly also has a rotation axis, and the components connected to it can also rotate around this axis. Therefore, the main structure of the rotating assembly 22 can rotate inside the housing module 1 around the rotation axis of the first rotating assembly, and the first camera 21 can rotate inside the housing module 1 around the rotation axis of the second rotating assembly. Simultaneously, since the first camera 21 is connected to the main structure of the rotating assembly 22, when the main structure of the rotating assembly 22 rotates inside the housing module 1 around the rotation axis of the first rotating assembly, the first camera 21 will rotate along with the rotating assembly 22 inside the housing module 1. In other words, the rotating assembly 22 will drive the first camera 21 to rotate inside the housing module 1 around the rotation axis of the first rotating assembly.

[0053] It should be noted that the rotation axis of the first rotating assembly is the first axis L1, and the rotation axis of the second rotating assembly is the second axis L2. The first rotating assembly and the second rotating assembly are two independent rotating parts, each responsible for different rotation directions, thereby realizing the multi-dimensional rotational movement of the first camera 21.

[0054] In this embodiment, the spherical shell 23 is nested within the front cover 11, and the first camera 21 is nested within the spherical shell 23. Therefore, when observing the camera device from the first observation hole 131 side, the spherical shell 23 can shield the various components inside the first camera 21, and the front cover 11 can shield the spherical shell 23 and the rotating assembly 22. In this way, the various components inside the camera device are not exposed, and the front cover 11 and the spherical shell 23 can also prevent dust, moisture, etc. from entering the camera device.

[0055] In one feasible embodiment, the rotating assembly 22 further includes a first rotating frame 223, wherein the first rotating frame 223 is composed of a base plate 2231, a first arcuate arm 2232, and a second arcuate arm 2233. The base plate 2231 is an elongated plate-like structure, which extends along a direction parallel to the second axis L2 after the rotating assembly 22 is assembled into the housing module 1. The first arcuate arm 2232 and the second arcuate arm 2233 are elongated structures with a certain curvature. The first arcuate arm 2232 and the second arcuate arm 2233 are respectively connected to the two sides of the base plate 2231, and with the center line of the base plate 2231 as the axis of symmetry, the first arcuate arm 2232 and the second arcuate arm 2233 extend on both sides of the base plate 2231 in a direction generally parallel to the first axis L1. The base plate 2231, the first arcuate arm 2232, and the second arcuate arm 2233 together form an approximately semi-annular structure.

[0056] The first arc-shaped arm 2232 has a first rotating shaft 22321 at its end, and the second arc-shaped arm 2233 has a second rotating shaft 22331 at its end. Both the first and second rotating shafts 22321 are cylindrical structures, located inside the aforementioned semi-annular structure, and are positioned opposite each other, with the first rotating shaft 22321 facing the second rotating shaft 22331. The centerline of the first rotating shaft 22321 coincides with the centerline of the second rotating shaft 22331, and the centerline of the first rotating shaft 22321 is distributed along the second axis L2. In other words, the centerline of the first rotating shaft 22321 lies on the second axis L2, and the centerline of the first rotating shaft 22321 is the second axis L2.

[0057] Furthermore, the first rotating assembly also includes an upper fixed bracket 2211 and a first bearing 2212. One end of the upper fixed bracket 2211 is fixedly connected to the inner wall of the front cover 11, and the other end of the upper fixed bracket 2211 is provided with a third rotating shaft 22111. The center line of the third rotating shaft 22111 is distributed along the first axis L1, that is, the center line of the third rotating shaft 22111 is located on the first axis L1. The substrate 2231 has a mounting hole (not shown). The first bearing 2212 can be press-fitted into the mounting hole or bolted to the top of the mounting hole, thereby using the substrate 2231 as a bearing seat. The third rotating shaft 22111 can pass through the mounting hole from below the substrate 2231 and then connect with the first bearing 2212 to form a bearing fit. In this way, the first bearing 2212 is connected to the substrate 2231 on one hand and to the third rotating shaft 22111 on the other hand, and the upper fixed bracket 2211 can be connected to the substrate 2231 through the first bearing 2212. Simultaneously, through the bearing cooperation between the first bearing 2212 and the third rotating shaft 22111, the substrate 2231 can also rotate around the center line of the third rotating shaft 22111, that is, the first rotating frame 223 can rotate around the center line of the third rotating shaft 22111. Figure 7 The view shown is for reference only. When the first rotating frame 223 is subjected to a horizontal force, the first rotating frame 223 can achieve horizontal rotation using the first bearing 2212. For example, when the user moves the first rotating frame 223 horizontally left or right, the first rotating frame 223 can rotate horizontally left or right.

[0058] In one feasible implementation, the second rotating assembly includes a first fixing plate 2221, a second bearing component 2222, a second fixing plate 2223, and a third bearing component 2224. The second bearing component 2222 is composed of a second bearing seat 22221 and a second bearing 22222, and the third bearing component 2224 is composed of a third bearing seat 22241 and a third bearing 22242. The two sides of the first camera 21 are respectively connected to the first fixing plate 2221 and the second fixing plate 2223. In practical applications, screw holes can be provided on the first fixing plate 2221 and the second fixing plate 2223, and corresponding screw openings can be provided on both sides of the first camera 21. Then, bolts are used to fix the first fixing plate 2221 and the second fixing plate 2223 to both sides of the first camera 21. The first fixing plate 2221 is fixedly connected to one side of the second bearing seat 22221 by bolts, and a support groove is provided on the other side of the second bearing seat 22221. The second bearing 22222 can be placed and fixed in the aforementioned support groove, and the first rotating shaft 22321 can be press-fitted onto the inner ring of the second bearing 22222, thereby forming a bearing fit between the second bearing 2222 and the first rotating shaft 22321. In this way, the second bearing 22222 can rotate around the centerline of the first rotating shaft 22321, driving the second bearing seat 22221 to rotate around the centerline of the first rotating shaft 22321, and further driving the first fixing plate 2221 to rotate around the centerline of the first rotating shaft 22321. In other words, the first fixing plate 2221 is rotatably connected to the first arc-shaped arm 2232 via the second bearing 2222. Figure 7 With reference to the shown viewpoint, the first arc-shaped arm 2232, the second bearing 22222, the second bearing seat 22221, the first fixing plate 2221, and the first camera 21 are arranged from left to right.

[0059] Furthermore, the second fixing plate 2223 is bolted to one side of the third bearing housing 22241, and a support groove is provided on the other side of the third bearing housing 22241. The third bearing 22242 can be placed and fixed in the support groove, and the second rotating shaft 22331 can be press-fitted onto the inner ring of the third bearing 22242, thereby forming a bearing fit between the third bearing component 2224 and the second rotating shaft 22331. In this way, the third bearing 22242 can rotate around the centerline of the second rotating shaft 22331, driving the third bearing housing 22241 to rotate around the centerline of the second rotating shaft 22331, and consequently driving the second fixing plate 2223 to rotate around the centerline of the second rotating shaft 22331. In other words, the second fixing plate 2223 is rotatably connected to the second arc-shaped arm 2233 via the third bearing component 2224. Figure 7 With reference to the shown viewpoint, the second arc-shaped arm 2233, the third bearing 22242, the third bearing seat 22241, the second fixing plate 2223, and the first camera 21 are arranged from right to left.

[0060] It should be noted that since the center line of the first rotating shaft 22321 coincides with the center line of the second rotating shaft 22331, the rotation of the second bearing 22222 and the rotation of the third bearing 22242 will not interfere with each other.

[0061] In this embodiment, the first camera 21 is rotatably connected to the first rotating frame 223 via a second bearing member 2222 and a third bearing member 2224. Figure 7 The shown viewpoint is for reference only. When the first camera 21 is subjected to a vertical force, it can rotate vertically using the second bearing 2222 and the third bearing 2224. For example, when the user moves the first camera 21 vertically up and down, it can rotate vertically around the rotation axis of the second bearing 22222 (i.e., the center line of the first rotating shaft 22321) or the rotation axis of the third bearing 22242 (i.e., the center line of the second rotating shaft 22331). Simultaneously, since the first camera 21 is connected to the first rotating frame 223, when the first rotating frame 223 rotates horizontally left and right, the first camera 21 will also rotate horizontally with the first rotating frame 223.

[0062] Optionally, the first bearing 2212 is a limiting bearing, which has internal structures such as stops to limit the rotation angle of the bearing. By selecting a suitable limiting bearing, the rotation range of the first rotating frame 223 in the horizontal direction can be ensured to be ±45 degrees, thereby ensuring that the rotation range of the first camera 21 in the horizontal direction is ±45 degrees.

[0063] Optionally, the second bearing 22222 and / or the third bearing 22242 are limiting bearings. By selecting suitable limiting bearings, it can be ensured that the rotation range of the first camera 21 in the vertical direction is 0 degrees to -45 degrees. For the specific structure of the limiting bearings, please refer to existing technology; details will not be elaborated here.

[0064] Optionally, the rotation axis of the first rotating assembly and the rotation axis of the second rotating assembly are configured to intersect perpendicularly, that is, the center line of the first rotating shaft 22321 intersects perpendicularly with the center line of the third rotating shaft 22111. In this way, the rotation axes of the first rotating assembly and the second rotating assembly will be located on the same plane, and the first rotating assembly and the second rotating assembly will be as close as possible to the same plane area, rather than occupying different space areas. The above structure can make the structure of the rotating assembly 22 more compact and ultimately reduce the volume of the first camera module 2.

[0065] In one feasible implementation, the second camera module 3 further includes a housing 33, which is approximately hemispherical and has a second viewing window 331. The second camera 31 is nested within the second viewing window 331. The diameter of the housing 33 is adapted to the diameter of the second observation hole 141, allowing the housing 33 to be rotatably nested within the second observation hole 141. The second observation hole 141 and the second viewing window 331 provide observation channels for the second camera 31, enabling the lens of the second camera 31 to capture images through the second observation hole 141 and the second viewing window 331. Simultaneously, to prevent the front cover 11 from obstructing the viewing angle of the second viewing window 331, when the housing 33 is nested within the second observation hole 141, the second viewing window 331 on the housing 33 must protrude from the second observation hole 141.

[0066] In this embodiment, the outer casing 33 is connected to the second camera 31 through the nesting action of the second viewing window 331. After the second camera 31 is nested in the second viewing window 331, the relative positional relationship between the outer casing 33 and the second camera 31 will be fixed, and the positional change of the outer casing 33 will be driven by the second camera 31. When the second camera 31 rotates, the outer casing 33 will rotate synchronously with the second camera 31. Since the outer casing 33 is rotatably nested in the second observation hole 141, when the outer casing 33 rotates with the second camera 31, the outer casing 33 can rotate in the second observation hole 141, and the front cover 11 will not hinder the rotation of the outer casing 33.

[0067] It should be noted that there is a relationship between the diameter of the second observation hole 141 and the rotation range of the second viewing window 331. The diameter of the second observation hole 141 must ensure that the second observation hole 141 will not obstruct the observation angle of the second viewing window 331 throughout the entire rotation range of the second viewing window 331.

[0068] In one feasible implementation, the second rotating assembly 32 includes a third rotating member and a fourth rotating member. The second rotating assembly 32 is connected to the rear cover 12 via the third rotating member, and the second camera 31 is connected to the main structure of the second rotating assembly 32 via the fourth rotating member. The rear cover 12 provides structural support for the second rotating assembly 32, and the second rotating assembly 32 provides structural support for the second camera 31. How the second rotating assembly 32 is connected to the rear cover 12 via the third rotating member, and how the second camera 31 is connected to the main structure of the second rotating assembly 32 via the fourth rotating member, will be explained in detail later.

[0069] In this embodiment, the third rotating assembly has a rotation axis, and the components connected to it can rotate around this axis. The fourth rotating assembly also has a rotation axis, and the components connected to it can also rotate around this axis. Therefore, the main structure of the second rotating assembly 32 can rotate inside the housing module 1 around the rotation axis of the third rotating assembly, and the second camera 31 can rotate inside the housing module 1 around the rotation axis of the fourth rotating assembly. Simultaneously, since the second camera 31 is connected to the main structure of the second rotating assembly 32, when the main structure of the second rotating assembly 32 rotates inside the housing module 1 around the rotation axis of the third rotating assembly, the second camera 31 will follow the second rotating assembly 32 and rotate inside the housing module 1. In other words, the second rotating assembly 32 will drive the second camera 31 to rotate inside the housing module 1 around the rotation axis of the third rotating assembly.

[0070] It should be noted that the rotation axis of the third rotating assembly is the third axis L3, and the rotation axis of the fourth rotating assembly is the fourth axis L4. The third and fourth rotating assemblies are two independent rotating parts, each responsible for different rotation directions, thereby realizing the multi-dimensional rotational motion of the second camera 31.

[0071] In this embodiment, since the outer casing 33 is nested within the front cover 11, and the second camera 31 is nested within the outer casing 33, when observing the camera device from the second observation hole 141 side, the outer casing 33 can shield the various components inside the second camera 31, and the front cover 11 can shield the outer casing 33 and the second rotating assembly 32. This prevents the various components inside the camera device from being exposed, and the front cover 11 and the outer casing 33 can also prevent dust, moisture, etc., from entering the camera device.

[0072] In one feasible embodiment, the second rotating assembly 32 further includes a second rotating frame 323, wherein the second rotating frame 323 is composed of an end plate 3231, a first support arm 3232, and a second support arm 3233. The end plate 3231 is a plate-shaped symmetrical structure, and when the second rotating assembly 32 is assembled into the housing module 1, the end plate 3231 will extend along a direction parallel to the fourth axis L4. The first support arm 3232 and the second support arm 3233 are respectively connected to both sides of the end plate 3231, and with the axis of symmetry of the end plate 3231 as the center of symmetry, the end plate 3231, the first support arm 3232, and the second support arm 3233 form a symmetrical structure. The first support arm 3232 and the second support arm 3233 extend on both sides of the end plate 3231 along a direction parallel to the third axis L3.

[0073] Furthermore, the first support arm 3232 is provided with a first mounting hole 32321, and the second support arm 3233 is provided with a second mounting hole 32331. The first mounting hole 32321 and the second mounting hole 32331 are used to place relevant components in the fourth rotating assembly. To avoid interference between rotating components in the fourth rotating assembly, the axis of the first mounting hole 32321 coincides with the axis of the second mounting hole 32331, which will be explained in detail later.

[0074] In one feasible embodiment, the third rotating assembly includes an annular frame 3211 and a first rotating motor 3212. The annular frame 3211 consists of a protruding tongue end 32111 and an annular end 32112. The protruding tongue end 32111 has a screw hole, which can be connected to a screw hole on the rear cover 12 via bolts, thereby fixing the annular frame 32111 to the rear cover 12. The annular end 32112 has an opening whose shape matches the contour of the housing of the first rotating motor 3212, allowing the annular end 32112 to be fitted onto the housing of the first rotating motor 3212. After the annular end 32112 is fitted onto the housing of the first rotating motor 3212, the annular end 32112 and the housing of the first rotating motor 3212 can be further secured with bolts to strengthen the connection between the annular frame 3211 and the first rotating motor 3212.

[0075] Furthermore, the shaft of the first rotating motor 3212 is fixedly connected to the end plate 3231 by bolts. Thus, the second rotating frame 323 can be connected to the annular frame 321 via the first rotating motor 3212, and subsequently to the rear cover 12. The rear cover 12 provides structural support for the second rotating frame 323, securing it inside the housing module 1. Simultaneously, the annular frame 321 serves as the mounting base for the first rotating motor 3212, ensuring that the torque generated by the first rotating motor 3212 is safely and effectively transmitted to the second rotating frame 323, allowing the second rotating frame 323 to rotate around the shaft of the first rotating motor 3212. In this embodiment, driven by the first rotating motor 3212, the second rotating frame 323 can rotate around the shaft of the first rotating motor 3212. For example, with... Figure 13 The view shown is for reference only. The first rotating motor 3212 can drive the second rotating frame 323 to rotate horizontally left and right.

[0076] It should be noted that the installation position of the first rotating motor 3212 is related to the position of the third axis L3. After the first rotating motor 3212 is fixedly connected to the end plate 3231, the rotating shaft of the first rotating motor 3212 needs to be distributed along the third axis L3, that is, the center line of the rotating shaft of the first rotating motor 3212 coincides with the third axis L3.

[0077] In one feasible implementation, the fourth rotating assembly includes a left fixed plate 3221, a left bearing 3222, a right fixed plate 3223, and a second rotating motor 3224. The two sides of the second camera 31 are connected to the left fixed plate 3221 and the right fixed plate 3223, respectively. In practical applications, screw holes can be provided on the left fixed plate 3221 and the right fixed plate 3223, and corresponding screw openings can be provided on both sides of the second camera 31. Then, bolts are used to fix the left fixed plate 3221 and the right fixed plate 3223 to both sides of the second camera 31. The left bearing 3222 is fitted into the first mounting hole 32321, and the left fixed plate 3221 is connected to the housing of the left bearing 3222 by bolts. Thus, the left fixed plate 3221 can be rotatably connected to the first support arm 3232 using the left bearing 3222. The housing of the second rotating motor 3224 is fitted into the second mounting hole 32331 and connected to the second support arm 3233 by bolts. Meanwhile, the rotating shaft inside the second rotating motor 3224 is bolted to the right fixed plate 3223, so that the right fixed plate 3223 can be rotatably connected to the second support arm 3233 through the second rotating motor 3224. When the second rotating motor 3224 is working, it can drive the right fixed plate 3223 to rotate.

[0078] It should be noted that after the second rotating motor 3224 is fitted into the second mounting hole 32331, the center line of the rotating shaft of the second rotating motor 3224 must coincide with the axis of the second mounting hole 32331, and the rotating shaft of the second rotating motor 3224 is distributed along the fourth axis L4, that is, the center line of the rotating shaft of the second rotating motor 3224 coincides with the fourth axis L4.

[0079] In this embodiment, the second camera 31 is rotatably connected to the second rotating frame 323 via a left bearing 3222 and a second rotating motor 3224. Figure 13 The shown perspective is for reference only. When the second rotation motor 3224 is working, it drives the second camera 31 to rotate vertically up and down around its axis. When the first rotation motor 3212 is working, it drives the second rotating frame 323 to rotate horizontally left and right. Since the second camera 31 is connected to the first support arm 3232 and the second support arm 3233 via the left fixing plate 3221 and the right fixing plate 3223, the second camera 31 is connected to the second rotating frame 323. Therefore, when the second rotating frame 323 rotates horizontally left and right, the second camera 31 will also rotate horizontally left and right along with the second rotating frame 323.

[0080] Optionally, the rotation axis of the third rotating assembly and the rotation axis of the fourth rotating assembly are configured to intersect perpendicularly, that is, the center line of the rotation shaft of the first rotating motor 3212 intersects perpendicularly with the center line of the rotation shaft of the second rotating motor 3224. In this way, the rotation axes of the third rotating assembly and the fourth rotating assembly will be located on the same plane, and the third rotating assembly and the fourth rotating assembly will be as close as possible to the same plane area, rather than occupying different spatial areas. The above structure can make the structure of the second rotating assembly 32 more compact and ultimately reduce the volume of the second camera module 3.

[0081] Optionally, the first camera 21 is a panoramic lens, and the second camera 31 is a close-up lens, thus enabling the camera device to have multi-view shooting capabilities. In this way, the camera device can capture both a wide background image and a rich array of detailed close-up images, thereby achieving comprehensive observation of a large scene.

[0082] Optionally, the housing module 1 also includes a transparent cover 15, which is disposed in the second observation hole 141 and protrudes outward from the second observation hole 141. The transparent cover 15 can protect the internal components of the second camera 31 from dust, moisture or other external factors, and extend the service life of the second camera 31.

[0083] Based on the same inventive concept, this application also provides a rotating assembly having a first axis L1 and a second axis L2, wherein the first axis L1 is different from the second axis L2. The rotating assembly is connected to a first camera 21 so that the first camera 21 can rotate around the first axis L1 and the second axis L2. The rotating assembly includes a first rotating frame 223, which has a base plate 2231, a first arcuate arm 2232 and a second arcuate arm 2233. The base plate 2231 extends in a direction parallel to the second axis L2. The first arcuate arm 2232 and the second arcuate arm 2233 are respectively connected to both sides of the base plate 2231 and extend on both sides of the base plate 2231 in a direction parallel to the first axis L1.

[0084] The first arc-shaped arm 2232 has a first rotating shaft 22321 at its end, and the second arc-shaped arm 2233 has a second rotating shaft 22331 at its end. Both the first and second rotating shafts 22321 are cylindrical structures. The first and second rotating shafts 22321 are positioned opposite each other, with the first rotating shaft 22321 facing the second rotating shaft 22331. The centerline of the first rotating shaft 22321 coincides with the centerline of the second rotating shaft 22331, and the centerline of the first rotating shaft 22321 is distributed along the second axis L2. In other words, the centerline of the first rotating shaft 22321 is located on the second axis L2, and the centerline of the first rotating shaft 22321 is the second axis L2.

[0085] Furthermore, the rotating assembly also includes an upper fixed bracket 2211 and a first bearing 2212. One end of the upper fixed bracket 2211 is used to connect to the support body, and the other end of the upper fixed bracket 2211 is provided with a third rotating shaft 22111. The center line of the third rotating shaft 22111 is distributed along the first axis L1, that is, the center line of the third rotating shaft 22111 is located on the first axis L1. The third rotating shaft 22111 is connected to the first bearing 2212 to form a bearing fit, and the first bearing 2212 is connected to the upper fixed bracket 2211 to connect the upper fixed bracket 2211 to the base plate 2231, so that the first rotating frame 223 can rotate around the center line of the third rotating shaft 22111.

[0086] Furthermore, the rotating assembly also includes a first fixing plate 2221, a second bearing member 2222, a second fixing plate 2223, and a third bearing member 2224. The two sides of the first camera 21 are respectively connected to the first fixing plate 2221 and the second fixing plate 2223. The first fixing plate 2221 is fixedly connected to the second bearing member 2222, and the second bearing member 2222 is connected to the first rotating shaft 22321 to form a bearing engagement, thereby rotatably connecting the first fixing plate 2221 to the first arc-shaped arm 2232. The second fixing plate 2223 is fixedly connected to the third bearing member 2224, and the third bearing member 2224 is connected to the second rotating shaft 22331 to form a bearing engagement, thereby rotatably connecting the second fixing plate 2223 to the second arc-shaped arm 2233.

[0088] Based on the same inventive concept, this application also provides a rotating assembly having a third axis L3 and a fourth axis L4, wherein the third axis L3 is different from the fourth axis L4. This rotating assembly is connected to a second camera 31 so that the second camera 31 can rotate around the third axis L3 and the fourth axis L4. The rotating assembly includes a second rotating frame 323, which has an end plate 3231, a first support arm 3232, and a second support arm 3233.

[0090] Furthermore, the aforementioned rotating assembly includes an annular frame 3211 and a first rotating motor 3212. The protruding end 32111 of the annular frame 3211 is fixedly connected to the support body, and the annular end 32112 of the annular frame 3211 is nested on the housing of the first rotating motor 3212. An end plate 3231 is fixedly connected to the rotating shaft of the first rotating motor 3212, allowing the second rotating frame 323 to rotate around the rotating shaft of the first rotating motor 3212, which is distributed along a third axis L3.

[0092] For details regarding the specific structure of the rotating component, please refer to the above embodiments; further details will not be provided here.

[0093] Therefore, the technical solution provided in this application includes a camera device housing with two angled observation holes, and two camera modules, a first camera module and a second camera module, are installed inside the housing. These two camera modules are rotatably nested within the observation holes. This allows the first and second camera modules to have different shooting angles, thereby expanding the overall observation range of the camera device. Furthermore, the first camera module is equipped with a rotating component, which allows for horizontal and vertical rotation to further expand the viewing angle. The second camera module is equipped with a second rotating component, which also allows for horizontal and vertical rotation to expand the viewing angle. The rotating components are independent of each other and do not interfere with each other during rotation, allowing the first and second camera modules to rotate independently. In the solution of this application, since the camera device has two independently rotatable camera modules, different types of lenses can be selected for the two camera modules according to actual needs. For example, the first camera module can be equipped with a panoramic lens, and the second camera module can be equipped with a close-up lens. Combined with the angled installation method, the blind spots of the camera device can be minimized to achieve comprehensive observation of a large scene.
