Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and particularly relates to a camera device and a rotating assembly. Background Art

[0002] A camera device is a device for capturing images and videos, which has wide applications in fields such as security monitoring and video communication. The field of view and shooting angle of a camera device are important performance indicators, which directly affect the shooting effect of the camera device.

[0003] Generally, a camera device has a fixed field of view, which is related to the size and resolution of the image sensor. If the scene to be observed is very large, the camera device may not be able to cover the entire area, and blind spots are likely to occur during shooting. The shooting angle of a camera device is determined by its installation position and lens direction. If the camera device is fixedly installed, it can only capture objects within a certain angle in front of the lens. In order to increase the shooting range of the camera device, the larger the field of view and shooting angle of the camera device, the better.

[0004] However, due to factors such as the size of the image sensor, imaging principle, and installation height, the current camera devices have relatively small fields of view and shooting angles, and cannot achieve a comprehensive observation of a large scene. Summary of the Utility Model

[0005] The purpose of this application is to provide a camera device and a rotating assembly, which can achieve a comprehensive observation of a large scene.

[0006] To achieve the above purpose, on the one hand, this application provides a camera device, which at least includes a housing module, a first camera module, and a second camera module. Among them, the housing module has a first surface body and a second surface body. The first surface body is located above the second surface body, and the first surface body and the second surface body are arranged at an angle. The first surface body is provided with a first observation hole, and the second surface body is provided with a second observation hole; the first camera module is located inside the housing module and is rotatably nested in the first observation hole; the second camera module is located inside the housing module and is rotatably nested in the second observation hole.

[0007] To achieve the above object, on the other hand, the present application provides a rotating assembly, the rotating assembly having a first axis and a second axis, the first axis being different from the second axis, the rotating assembly being connected to a first camera such that the first camera can rotate about the first axis and the second axis; the rotating assembly includes a first rotating frame, the first rotating frame having a substrate, a first arc-shaped arm, and a second arc-shaped arm, the substrate extending in a direction parallel to the second axis, the first arc-shaped arm and the second arc-shaped arm being respectively connected to both sides of the substrate and extending along a direction parallel to the first axis on both sides of the substrate; a first rotating shaft is provided at the end of the first arc-shaped arm, a second rotating shaft is provided at the end of the second arc-shaped arm, the first rotating shaft and the second rotating shaft are oppositely arranged, 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.

[0008] To achieve the above object, on the other hand, the present application provides a rotating assembly, the rotating assembly having a third axis and a fourth axis, the third axis being different from the fourth axis, the rotating assembly being connected to a second camera such that the second camera can rotate about the third axis and the fourth axis; the rotating assembly includes a second rotating frame, the second rotating frame having an end plate, a first support arm, and a second support arm, wherein the end plate extends in a direction parallel to the fourth axis, the first support arm and the second support arm are respectively connected to both sides of the end plate and extend along a direction parallel to the third axis; a first mounting hole is provided in the first support arm, a second mounting hole is provided in the second support arm, and the axis of the first mounting hole coincides with the axis of the second mounting hole.

[0009] It can be seen that in the technical solution provided by the present application, the housing of the imaging device is provided with two observation holes arranged at an angle, and two imaging modules, namely a first imaging module and a second imaging module, are installed inside the housing of the imaging device. These two imaging modules are respectively rotatably nested in the above-mentioned observation holes. In this way, the first imaging module and the second imaging module have different shooting angles, thereby expanding the observation range of the entire imaging device. Further, the first imaging module is equipped with a first rotation assembly, which can achieve horizontal rotation and vertical rotation by using the first rotation assembly to expand the viewing angle range. The second imaging module is equipped with a second rotation assembly, which can achieve horizontal rotation and vertical rotation by using the second rotation assembly to expand the viewing angle range. The first rotation assembly and the second rotation assembly are independent of each other, and the two will not interfere with each other during rotation, so that the first imaging module and the second imaging module can rotate independently. In the solution of the present application, since the imaging device has two independently rotatable imaging modules, different types of lenses can be selected for these two imaging modules according to actual needs. For example, a panoramic lens can be selected for the first imaging module, and a telephoto lens can be selected for the second imaging module. Combined with the installation method arranged at an angle, the shooting blind area of the imaging device can be minimized to achieve a comprehensive observation of a large scene.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings. Relative spatial position terms used in this application, such as "upper", "above", "lower", "below", "first end", "second end", "one end", "the other end", etc., are used for the purpose of facilitating explanation to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The relative spatial position terms may be intended to include different orientations of the device in addition to the orientation shown in the figures during use or operation. For example, if the device in the figure is flipped, the unit described as being "below" or "beneath" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both the upper and lower orientations. The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein can be interpreted accordingly.

[0029] In addition, the terms "installed", "set up", "provided with", "connected", "slidably connected", "fixed", "socketed" should be understood in a broad sense. For example, "connected" 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 directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] A camera device is a device that captures images and videos, and it has a wide range of applications in fields such as security monitoring and video communication. The field of view and shooting angle of a camera device are important performance indicators, and the above indicators directly affect the range of scenes that the camera can capture.

[0031] The field of view of a camera device refers to the spatial area of the entire scene that the camera lens can capture. After most camera devices are installed, the field of view they can capture is fixed, and the size of the above field of view is related to the size and resolution of the image sensor. If the scene to be observed is larger than the field of view of the camera lens, then the camera lens cannot capture the entire scene at once, which may result in some areas not being covered by the camera device, thereby forming a shooting blind spot. The shooting angle of a camera device refers to the angular range that the camera lens can cover, usually measured in angles, such as the horizontal field of view angle, the vertical field of view angle, or the diagonal field of view angle. The shooting angle of a camera device is determined by its installation position and lens direction. If the camera device is fixedly installed, then it can only capture objects within a certain angle in front of the lens.

[0032] In order to increase the shooting range of a camera device, the larger the viewing range and shooting angle of the camera device, the better. However, due to factors such as the size of the image sensor, imaging principle, and installation height, the current camera devices have relatively small viewing ranges and shooting angles. Due to these limitations, when monitoring wide spaces such as large conference rooms, shopping malls, or outdoor areas, the camera devices may not be able to comprehensively observe these scenes.

[0033] Therefore, how to improve the structure of the camera device so that it can comprehensively observe larger scenes has become an urgent problem to be solved in this field.

[0034] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments of the present application are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0035] The present application provides a camera device. Please also refer to Figures 1 to 16 As shown, in an achievable embodiment, 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 is mainly composed of a front cover 11 and a rear cover 12. After the front cover 11 and the rear cover 12 are assembled together, a receiving space can be formed, and the first camera module 2 and the second camera module 3 are placed in the above receiving space, that is, the first camera module 2 and the second camera module 3 are located inside the housing module 1. The housing module 1 can not only protect the first camera module 2 and the second camera module 3 from the intrusion of impurities such as dust and rain and fog, but also provide stable physical support for the first camera module 2 and the second camera module 3 to ensure their stability after installation.

[0036] Two planes are provided on the surface of the housing module 1, which are respectively denoted as a first plane body 13 and a second plane body 14. Specifically, the first plane body 13 and the second plane body 14 can be provided on the front cover 11, and Figure 1Taking the shown perspective as a reference, the first surface body 13 is arranged above the second surface body 14. A first observation hole 131 is formed in the first surface body 13, and a second observation hole 141 is formed in the second surface body 14. The first camera module 2 is nested in the first observation hole 131 to capture images through the first observation hole 131, and the first camera module 2 is rotatably nested in the first observation hole 131, that is, the first camera module 2 can rotate in the first observation hole 131, so as to expand the shooting angle of the first camera module 2. The second camera module 3 is nested in the second observation hole 141 to capture images through the second observation hole 141, and the second camera module 3 is rotatably nested in the second observation hole 141, that is, the second camera module 3 can rotate in the second observation hole 141, so as to expand the shooting angle of the second camera module 3.

[0037] In this embodiment, the first surface body 13 and the second surface body 14 are arranged at an angle, that is, the first surface body 13 and the second surface body 14 are not parallel, but are inclined to each other at a certain angle, so that the first observation hole 131 and the second observation hole 141 are also arranged at an angle. Since the first camera module 2 and the second camera module 3 are respectively nested in the first observation hole 131 and the second observation hole 141, the first camera module 2 and the second camera module 3 will have different lens mounting angles inside the housing module 1, and the first camera module 2 and the second camera module 3 can capture images from different shooting angles to cover each other's blind spots, thereby improving the observation range of the entire scene.

[0038] For example, assume that the imaging device is installed on a vertical wall, and at this time the first surface body 13 is perpendicular to the ground. When the first surface body 13 and the second surface body 14 are in the same plane, the second camera module 3 located below the first camera module 2 has a shooting blind area approximately as Figure 5a the shaded area in. When the first surface body 13 and the second surface body 14 are arranged at an angle, the second camera module 3 located below the first camera module 2 has a shooting blind area approximately as Figure 5b the shaded area in. Obviously, when the first surface body 13 and the second surface body 14 are arranged at an angle, the shooting blind area of the second camera module 3 is smaller. As Figure 5c shown, regarding the shooting blind area of the second camera module 3, it can be calculated by the following formula, M = H * tg(θ), θ = 90° - α - β / 2, where α is the included angle between the second surface body 14 and the first surface body 13, β is the vertical field of view angle 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 shooting blind area of the second camera module 3 on the ground.

[0039] Further, the first imaging module 2 includes a first camera 21 and a first rotating assembly 22. The first camera 21 is used to capture images. The first rotating assembly 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 first rotating assembly 22 has two different rotation axes, respectively denoted as the first axis L1 and the second axis L2, and the first camera 21 can rotate around the first axis L1 or around the second axis L2.

[0040] Further, the second imaging module 3 includes a second camera 31 and a second rotating assembly 32. The second camera 31 is used to capture images. The second rotating assembly 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 assembly 32 has two different rotation axes, respectively denoted as the third axis L3 and the fourth axis L4, and the second camera 31 can rotate around the third axis L3 or around the fourth axis L4.

[0041] It should be noted that the first rotating assembly 22 and the second rotating assembly 32 are two independent rotating mechanisms, and there is no interference when the first rotating assembly 22 and the second rotating assembly 32 rotate. When the first rotating assembly 22 rotates, the second rotating assembly 32 can rotate or not rotate. Correspondingly, when the second rotating assembly 32 rotates, the first rotating assembly 22 can rotate or not rotate.

[0042] In an implementable embodiment, the first imaging module 2 further includes a spherical shell 23. The spherical shell 23 is provided with a first viewing hole 231, and the first camera 21 is nested in the first viewing hole 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 can be rotatably nested in the first observation hole 131. The first observation hole 131 and the first viewing hole 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 hole 231. At the same time, to avoid the front cover 11 blocking the viewing angle of the first viewing hole 231, when the spherical shell 23 is nested in the first observation hole 131, the first viewing hole 231 on the spherical shell 23 needs to be exposed from the first observation hole 131.

[0043] In this embodiment, the spherical shell 23 is connected to the first camera 21 through the nesting effect of the first window hole 231. After the first camera 21 is nested in the first window hole 231, the relative positional relationship between the spherical shell 23 and the first camera 21 will be fixed accordingly, and the position change of the spherical shell 23 is 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 following 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.

[0044] It should be noted that when constructing the spherical shell 23, a circular notch a can be formed on the surface of a spherical structure to form the first window hole 231, and a circular notch b is formed on the side opposite to the first window hole 231. The centers 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 from the circular notch b, and then nest the lens 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 window hole 231. The diameter of the first observation hole 131 needs to satisfy that within the entire rotation range of the first window hole 231, the first observation hole 131 will not block the viewing angle of the first window hole 231.

[0045] In an implementable embodiment, the first rotating assembly 22 includes a first rotating member and a second rotating member. Among them, the first rotating assembly 22 is connected to the front cover 11 through the first rotating member, and the first camera 21 is connected to the main body structure of the first rotating assembly 22 through the second rotating member. The front cover 11 can provide a force support for the first rotating assembly 22, and the first rotating assembly 22 can provide a force support for the first camera 21. How the first rotating assembly 22 is connected to the front cover 11 through the first rotating member and how the first camera 21 is connected to the main body structure of the first rotating assembly 22 through the second rotating member will be described in detail later.

[0046] In this embodiment, the first rotating component has a rotating axis, and the components connected thereto can rotate around its rotating axis. The second rotating component also has a rotating axis, and the components connected thereto can also rotate around its rotating axis. Therefore, the main structure of the first rotating assembly 22 can rotate inside the housing module 1 around the rotation axis of the first rotating component, and the first camera 21 can rotate inside the housing module 1 around the rotation axis of the second rotating component. At the same time, since the first camera 21 is connected to the main structure of the first rotating assembly 22, when the main structure of the first rotating assembly 22 rotates inside the housing module 1 around the rotation axis of the first rotating component, the first camera 21 will follow the first rotating assembly 22 and rotate inside the housing module 1. In other words, the first rotating assembly 22 will drive the first camera 21 to rotate inside the housing module 1 around the rotation axis of the first rotating component.

[0047] It should be noted that the rotation axis of the first rotating component is the first axis L1, and the rotation axis of the second rotating component is the second axis L2. The first rotating component and the second rotating component are two independently rotating parts, and they are respectively responsible for different rotation directions, so as to realize the multi-dimensional rotation movement of the first camera 21.

[0048] In this embodiment, since the spherical shell 23 is nested in the front cover 11 and the first camera 21 is nested in the spherical shell 23. Therefore, when observing the imaging device from the side of the first observation hole 131, the spherical shell 23 can block various devices inside the first camera 21, and the front cover 11 can block the spherical shell 23 and the first rotating assembly 22, so that the various devices inside the imaging device are not exposed, and the front cover 11 and the spherical shell 23 can also prevent dust, moisture, etc. from entering the inside of the imaging device.

[0049] In an implementable embodiment, the first rotating assembly 22 further includes a first rotating frame 223. Among them, the first rotating frame 223 is composed of a substrate 2231, a first arc arm 2232 and a second arc arm 2233. The substrate 2231 is a long strip plate-like structure. After the first rotating assembly 22 is assembled inside the housing module 1, the substrate 2231 will extend along a direction parallel to the second axis L2. The first arc arm 2232 and the second arc arm 2233 are long strip structures and have a certain curvature. The first arc arm 2232 and the second arc arm 2233 are respectively connected to both sides of the substrate 2231, and with the center line of the substrate 2231 as the symmetry axis, the first arc arm 2232 and the second arc arm 2233 generally extend along a direction parallel to the first axis L1 on both sides of the substrate 2231. The substrate 2231, the first arc arm 2232 and the second arc arm 2233 together form a structure approximately in the shape of a semi-ring.

[0050] The end of the first arc-shaped arm 2232 is provided with a first rotating shaft 22321, and the end of the second arc-shaped arm 2233 is provided with a second rotating shaft 22331. Both the first rotating shaft 22321 and the second rotating shaft 22331 are cylindrical structures. The first rotating shaft 22321 and the second rotating shaft 22331 are located inside the above semi-circular structure, and the first rotating shaft 22321 and the second rotating shaft 22331 are arranged oppositely, that is, the first rotating shaft 22321 faces the second rotating shaft 22331. The center line of the first rotating shaft 22321 coincides with the center line of the second rotating shaft 22331, and the center line of the first rotating shaft 22321 is distributed along the second axis L2. In other words, the center line of the first rotating shaft 22321 is located on the second axis L2, and the center line of the first rotating shaft 22321 is the second axis L2.

[0051] Further, the first rotating assembly further includes an upper fixing bracket 2211 and a first bearing 2212. One end of the upper fixing bracket 2211 is fixedly connected to the inner wall of the front cover 11, and the other end of the upper fixing 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 is provided with a mounting hole (not shown). The first bearing 2212 can be press-fitted into the above mounting hole or connected above the mounting hole by bolts, so that the substrate 2231 serves as a bearing seat. The third rotating shaft 22111 can pass through the above mounting hole from below the substrate 2231 and then be connected to the first bearing 2212 to form a bearing fit. In this way, the first bearing 2212 is connected to the substrate 2231 on the one hand and to the third rotating shaft 22111 on the other hand, and the upper fixing bracket 2211 can be connected to the substrate 2231 through the first bearing 2212. At the same time, through the bearing fit 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 Taking the shown perspective as a reference, when the first rotating frame 223 is subjected to a horizontal force, the first rotating frame 223 can achieve horizontal rotation by using the first bearing 2212. For example, when the user horizontally toggles the first rotating frame 223 left and right, the first rotating frame 223 can rotate horizontally left and right.

[0052] In an implementable embodiment, the second rotating component includes a first fixing plate 2221, a second bearing member 2222, a second fixing plate 2223, and a third bearing member 2224. Among them, the second bearing member 2222 is composed of a second bearing seat 22221 and a second bearing 22222, and the third bearing member 2224 is composed of a third bearing seat 22241 and a third bearing 22242. Both 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 threads can be provided on both sides of the first camera 21, and then the first fixing plate 2221 and the second fixing plate 2223 can be fixed on both sides of the first camera 21 by using bolts. 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 above support groove, and the first rotating shaft 22321 can be press-fitted on the inner ring of the second bearing 22222, so that the second bearing member 2222 forms a bearing fit with the first rotating shaft 22321. In this way, the second bearing 22222 can rotate around the center line of the first rotating shaft 22321, drive the second bearing seat 22221 to rotate around the center line of the first rotating shaft 22321, and further drive the first fixing plate 2221 to rotate around the center line of the first rotating shaft 22321. In other words, the first fixing plate 2221 is rotatably connected to the first arc-shaped arm 2232 through the second bearing member 2222. Taking Figure 7 the shown perspective as a reference, 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 in sequence from left to right.

[0053] Furthermore, the second fixing plate 2223 is fixedly connected to one side of the third bearing seat 22241 by bolts, and a support groove is provided on the other side of the third bearing seat 22241. The third bearing 22242 can be placed and fixed in the above support groove, and the second rotating shaft 22331 can be press-fitted on the inner ring of the third bearing 22242, so that the third bearing member 2224 forms a bearing fit with the second rotating shaft 22331. In this way, the third bearing 22242 can rotate around the center line of the second rotating shaft 22331, drive the third bearing seat 22241 to rotate around the center line of the second rotating shaft 22331, and further drive the second fixing plate 2223 to rotate around the center line of the second rotating shaft 22331. In other words, the second fixing plate 2223 is rotatably connected to the second arc-shaped arm 2233 through the third bearing member 2224. Taking Figure 7 the shown perspective as a reference, 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 in sequence from right to left.

[0054] It should be noted that, since the center lines of the first rotating shaft 22321 and the second rotating shaft 22331 coincide, the rotation of the second bearing 22222 and the rotation of the third bearing 22242 will not interfere with each other at this time.

[0055] In this embodiment, the first camera 21 is rotatably connected to the first rotating frame 223 by means of the second bearing member 2222 and the third bearing member 2224. Figure 7 Taking the shown perspective as a reference, when a vertical force is applied to the first camera 21, the first camera 21 can achieve vertical rotation by means of the second bearing member 2222 and the third bearing member 2224. For example, when the user vertically toggles the first camera 21 up and down, the first camera 21 can vertically rotate up and down 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). At the same time, 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 left and right following the first rotating frame 223.

[0056] Optionally, the first bearing 2212 is a limiting bearing, and structures such as stoppers are provided inside the limiting bearing, which can limit the rotation angle of the bearing. By selecting a suitable limiting bearing, it can be ensured that the rotation range of the first rotating frame 223 in the horizontal direction is ±45 degrees, so that the rotation range of the first camera 21 in the horizontal direction is ±45 degrees.

[0057] Optionally, the second bearing 22222 and / or the third bearing 22242 is a limiting bearing. By selecting a suitable limiting bearing, it can be ensured that the rotation range of the first camera 21 in the vertical direction is from 0 degrees to -45 degrees. For the specific structure of the limiting bearing, reference can be made to the prior art and will not be elaborated here.

[0058] Optionally, the rotation axis of the first rotating assembly and the rotation axis of the second rotating assembly are configured to be vertically intersecting, that is, the center line of the first rotating shaft 22321 and the center line of the third rotating shaft 22111 are vertically intersecting. In this way, the rotation axes of the first rotating assembly and the second rotating assembly will be in the same plane, and the first rotating assembly and the second rotating assembly will also be as close as possible to the same plane area, rather than each occupying different spatial areas. The above structure can make the structure of the first rotating assembly 22 more compact and ultimately reduce the volume of the first camera module 2.

[0059] In an achievable implementation manner, the second camera module 3 further includes a housing 33. The housing 33 is approximately hemispherical. The housing 33 is provided with a second viewing hole 331, and the second camera 31 is nested in the second viewing hole 331. The diameter of the housing 33 is adapted to the diameter of the second observation hole 141, so that the housing 33 is rotatably nested in the second observation hole 141. The second observation hole 141 and the second viewing hole 331 provide an observation channel for the second camera 31, so that the lens in the second camera 31 can capture images through the second observation hole 141 and the second viewing hole 331. At the same time, to prevent the front cover 11 from blocking the viewing angle of the second viewing hole 331, when the housing 33 is nested in the second observation hole 141, the second viewing hole 331 on the housing 33 needs to be exposed from the second observation hole 141.

[0060] In this implementation manner, the housing 33 is connected to the second camera 31 through the nesting function of the second viewing hole 331. After the second camera 31 is nested in the second viewing hole 331, the relative positional relationship between the housing 33 and the second camera 31 will be fixed accordingly, and the position change of the housing 33 is driven by the second camera 31. When the second camera 31 rotates, the housing 33 will rotate synchronously with the second camera 31. Since the housing 33 is rotatably nested in the second observation hole 141, when the housing 33 rotates with the second camera 31, the housing 33 can rotate in the second observation hole 141, and the front cover 11 will not hinder the rotation of the housing 33.

[0061] It should be noted that there is a connection between the diameter of the second observation hole 141 and the rotation range of the second viewing hole 331. The diameter of the second observation hole 141 needs to be such that within the entire rotation range of the second viewing hole 331, the second observation hole 141 will not block the viewing angle of the second viewing hole 331.

[0062] In an achievable implementation manner, the second rotation assembly 32 includes a third rotating part and a fourth rotating part. Among them, the second rotation assembly 32 is connected to the rear cover 12 through the third rotating part, and the second camera 31 is connected to the main body structure of the second rotation assembly 32 through the fourth rotating part. The rear cover 12 can provide a force support for the second rotation assembly 32, and the second rotation assembly 32 can provide a force support for the second camera 31. How the second rotation assembly 32 is connected to the rear cover 12 through the third rotating part and how the second camera 31 is connected to the main body structure of the second rotation assembly 32 through the fourth rotating part will be described in detail later.

[0063] In this embodiment, the third rotating assembly has a rotating axis, and the components connected thereto can rotate around its rotating axis. The fourth rotating assembly also has a rotating axis, and the components connected thereto can also rotate around its rotating 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. At the same time, 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.

[0064] 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 rotating assembly and the fourth rotating assembly are two independently rotating parts, and they are responsible for different rotation directions respectively, so as to realize the multi-dimensional rotational movement of the second camera 31.

[0065] In this embodiment, since the outer housing 33 is nested in the front cover 11, and the second camera 31 is nested in the outer housing 33. Therefore, when observing the imaging device from the side of the second observation hole 141, the outer housing 33 can block various devices inside the second camera 31, and the front cover 11 can block the outer housing 33 and the second rotating assembly 32, so that the various devices inside the imaging device will not be exposed, and the front cover 11 and the outer housing 33 can also prevent dust, moisture, etc. from entering the inside of the imaging device.

[0066] In an implementable embodiment, the second rotating assembly 32 further includes a second rotating frame 323. Among them, 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 symmetric structure. After the second rotating assembly 32 is assembled inside 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 symmetry axis 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 symmetric 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.

[0067] Further, a first mounting hole 32321 is provided on the first support arm 3232, and a second mounting hole 32331 is provided on the second support arm 3233. 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 of the rotating parts 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 described in detail later.

[0068] In an implementable embodiment, the third rotating assembly includes an annular frame 3211 and a first rotating motor 3212. The annular frame 3211 is composed of a lug end 32111 and an annular end 32112. A screw hole is provided on the lug end 32111, and it can be connected to the screw hole position on the rear cover 12 through a bolt, thereby fixing the annular frame 3211 on the rear cover 12. The annular end 32112 is provided with an opening, and the shape of the opening is adapted to the outer shell contour of the first rotating motor 3212, so that the annular end 32112 can be sleeved on the housing of the first rotating motor 3212. After the annular end 32112 is sleeved on the housing of the first rotating motor 3212, the annular end 32112 and the housing of the first rotating motor 3212 can also be fixed by bolts to strengthen the connection between the annular frame 3211 and the first rotating motor 3212.

[0069] Further, the rotating shaft of the first rotating motor 3212 is fixedly connected to the end plate 3231 through a bolt. In this way, the second rotating frame 323 can be connected to the annular frame 321 through the first rotating motor 3212, and then connected to the rear cover 12. The rear cover 12 can provide a force support for the second rotating frame 323 to fix the second rotating frame 323 inside the housing module 1. At the same time, the annular frame 321 is equivalent to the installation base of the first rotating motor 3212, and the annular frame 321 can ensure that the torque generated by the first rotating motor 3212 can be safely and effectively transmitted to the second rotating frame 323, so that the second rotating frame 323 can rotate around the rotating 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 rotating shaft of the first rotating motor 3212. For example, Figure 13 Taking the shown perspective as a reference, the first rotating motor 3212 can drive the second rotating frame 323 to rotate horizontally left and right.

[0070] It should be noted that there is a connection between the installation position of the first rotating motor 3212 and 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.

[0071] In an implementable embodiment, the fourth rotating member includes a left fixing plate 3221, a left bearing 3222, a right fixing plate 3223, and a second rotating motor 3224. Both sides of the second camera 31 are respectively connected to the left fixing plate 3221 and the right fixing plate 3223. In practical applications, screw holes can be provided on the left fixing plate 3221 and the right fixing plate 3223, and screw ports can be correspondingly provided on both sides of the second camera 31, and then the left fixing plate 3221 and the right fixing plate 3223 can be fixed on both sides of the second camera 31 by using bolts. The left bearing 3222 is sleeved in the first mounting hole 32321, and the left fixing plate 3221 is connected to the housing of the left bearing 3222 by bolts, so that the left fixing plate 3221 can be rotatably connected to the first support arm 3232 by using the left bearing 3222. The housing of the second rotating motor 3224 is sleeved in the second mounting hole 32331 and is connected to the second support arm 3233 by bolts. At the same time, the rotating shaft inside the second rotating motor 3224 is bolted to the right fixing plate 3223, so that the right fixing plate 3223 can be rotatably connected to the second support arm 3233 by using the second rotating motor 3224. When the second rotating motor 3224 works, the second rotating motor 3224 can drive the right fixing plate 3223 to rotate.

[0072] It should be noted that after the second rotating motor 3224 is sleeved in the second mounting hole 32331, the center line of the rotating shaft of the second rotating motor 3224 needs to 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.

[0073] In this embodiment, the second camera 31 is rotatably connected to the second rotating frame 323 by using the left bearing 3222 and the second rotating motor 3224. Taking Figure 13 the shown perspective as a reference, when the second rotating motor 3224 works, the second rotating motor 3224 can drive the second camera 31 to vertically rotate up and down around the rotating shaft of the second rotating motor 3224. When the first rotating motor 3212 works, the first rotating motor 3212 can drive the second rotating frame 323 to horizontally rotate left and right. Since the second camera 31 is connected to the first support arm 3232 and the second support arm 3233 through 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 horizontally rotates left and right, the second camera 31 will also horizontally rotate left and right following the second rotating frame 323.

[0074] Optionally, the rotation axis of the third rotating member and the rotation axis of the fourth rotating member are configured to be vertically intersecting, that is, the center line of the rotating shaft of the first rotating motor 3212 and the center line of the rotating shaft of the second rotating motor 3224 are vertically intersecting. In this way, the rotation axes of the third rotating member and the fourth rotating member will be located in the same plane, and the third rotating member and the fourth rotating member will also be as close as possible to the same plane area, rather than occupying different spatial areas respectively. The above structure can make the structure of the second rotating assembly 32 more compact and ultimately reduce the volume of the second imaging module 3.

[0075] Optionally, the first camera 21 is a panoramic lens, and the second camera 31 is a close-up lens, so that the imaging device has a multi-view shooting function. In this way, the imaging device can not only capture a wide background image but also obtain rich detailed close-up images, so as to achieve a comprehensive observation of a larger scene.

[0076] Optionally, the housing module 1 further includes a transparent cover 15. The transparent cover 15 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.

[0077] Based on the same inventive concept, the present application also provides a rotating assembly. The rotating assembly has a first axis L1 and a second axis L2, and the first axis L1 is different from the second axis L2. The rotating assembly is connected to the first camera 21 so that the first camera 21 can rotate around the first axis L1 and the second axis L2. The above rotating assembly includes a first rotating frame 223. The first rotating frame 223 has a substrate 2231, a first arc-shaped arm 2232 and a second arc-shaped arm 2233. The substrate 2231 extends in a direction parallel to the second axis L2. The first arc-shaped arm 2232 and the second arc-shaped arm 2233 are respectively connected to both sides of the substrate 2231 and extend along a direction parallel to the first axis L1 on both sides of the substrate 2231.

[0078] A first rotating shaft 22321 is provided at the end of the first arc-shaped arm 2232, and a second rotating shaft 22331 is provided at the end of the second arc-shaped arm 2233. Both the first rotating shaft 22321 and the second rotating shaft 22331 are cylindrical structures. The first rotating shaft 22321 and the second rotating shaft 22331 are oppositely arranged, that is, the first rotating shaft 22321 faces the second rotating shaft 22331. The center line of the first rotating shaft 22321 coincides with the center line of the second rotating shaft 22331, and the center line of the first rotating shaft 22321 is distributed along the second axis L2. In other words, the center line of the first rotating shaft 22321 is located on the second axis L2, and the center line of the first rotating shaft 22321 is the second axis L2.

[0079] Further, the rotating assembly further includes an upper fixing bracket 2211 and a first bearing 2212. One end of the upper fixing bracket 2211 is used for connecting with the support body, and the other end of the upper fixing bracket 2211 is provided with a third rotating shaft 22111. The central axis of the third rotating shaft 22111 is distributed along the first axis L1, that is, the central axis of the third rotating shaft 22111 is located on the first axis L1. The third rotating shaft 22111 is connected with the first bearing 2212 to form a bearing fit, and the first bearing 2212 is connected with the upper fixing bracket 2211 to connect the upper fixing bracket 2211 to the substrate 2231, and to enable the first rotating frame 223 to rotate around the central axis of the third rotating shaft 22111.

[0080] Further, the rotating assembly further includes a first fixing plate 2221, a second bearing member 2222, a second fixing plate 2223 and a third bearing member 2224. Both sides of the first camera 21 are respectively connected with the first fixing plate 2221 and the second fixing plate 2223. The first fixing plate 2221 is fixedly connected with the second bearing member 2222, and the second bearing member 2222 is connected with the first rotating shaft 22321 to form a bearing fit to rotatably connect the first fixing plate 2221 to the first arc-shaped arm 2232. The second fixing plate 2223 is fixedly connected with the third bearing member 2224, and the third bearing member 2224 is connected with the second rotating shaft 22331 to form a bearing fit to rotatably connect the second fixing plate 2223 to the second arc-shaped arm 2233.

[0081] Regarding the specific structure of the rotating assembly, reference may be made to the content in the above-mentioned embodiments, and details will not be elaborated here.

[0082] Based on the same inventive concept, the present application further provides a rotating assembly. The rotating assembly has a third axis L3 and a fourth axis L4, and the third axis L3 is different from the fourth axis L4. The rotating assembly is connected with the second camera 31 to enable the second camera 31 to rotate around the third axis L3 and the fourth axis L4. The above-mentioned rotating assembly includes a second rotating frame 323. The second rotating frame 323 has an end plate 3231, a first support arm 3232 and a second support arm 3233. The end plate 3231 extends in a direction parallel to the fourth axis L4, and the first support arm 3232 and the second support arm 3233 are respectively connected to both sides of the end plate 3231 and extend in a direction parallel to the third axis L3.

[0083] Further, the first support arm 3232 is provided with a first mounting hole 32321, the second support arm 3233 is provided with a second mounting hole 32331, and the axis of the first mounting hole 32321 coincides with the axis of the second mounting hole 32331.

[0084] Furthermore, the above-mentioned rotating assembly includes an annular frame 3211 and a first rotating motor 3212. Among them, the tongue end 32111 of the annular frame 3211 is used for fixedly connecting with the support body, and the annular end 32112 of the annular frame 3211 is nested on the housing of the first rotating motor 3212. The end plate 3231 is fixedly connected to the rotating shaft of the first rotating motor 3212, so that the second rotating frame 323 can rotate around the rotating shaft of the first rotating motor 3212, and the rotating shaft of the first rotating motor 3212 is distributed along the third axis L3.

[0085] Furthermore, the above-mentioned rotating assembly further includes a left fixing plate 3221, a left bearing 3222, a right fixing plate 3223 and a second rotating motor 3224. Both sides of the second camera 31 are connected to the left fixing plate 3221 and the right fixing plate 3223 respectively. The left bearing 3222 is sleeved in the first mounting hole 32321 and connected to the left fixing plate 3221, so that the left fixing plate 3221 is rotatably connected to the first support arm 3232. The second rotating motor 3224 is sleeved in the second mounting hole 32331, and the rotating shaft of the second rotating motor 3224 is connected to the right fixing plate 3223, so that the right fixing plate 3223 is rotatably connected to the second support arm 3233, and the rotating shaft of the second rotating motor 3224 is distributed along the fourth axis L4.

[0086] Regarding the specific structure of this rotating assembly, reference can be made to the content in the above-mentioned embodiments, and details will not be elaborated here.

[0087] Thus, it can be seen that in the technical solution provided by this application, the housing of the imaging device is provided with two observation holes arranged at an angle, and two imaging modules, namely a first imaging module and a second imaging module, are installed inside the housing of the imaging device. These two imaging modules are respectively rotatably nested in the above-mentioned observation holes. In this way, the first imaging module and the second imaging module have different shooting angles, thereby expanding the observation range of the entire imaging device. Furthermore, the first imaging module is equipped with a first rotating assembly, which can use the first rotating assembly to achieve horizontal rotation and vertical rotation to expand the viewing angle range. The second imaging module is equipped with a second rotating assembly, which can use the second rotating assembly to achieve horizontal rotation and vertical rotation to expand the viewing angle range. The first rotating assembly and the second rotating assembly are independent of each other, and they will not interfere with each other during rotation, so that the first imaging module and the second imaging module can rotate independently. In the solution of this application, since the imaging device has two independently rotatable imaging modules, different types of lenses can be selected for these two imaging modules according to actual needs. For example, a panoramic lens can be selected for the first imaging module, and a telephoto lens can be selected for the second imaging module. Combined with the installation method arranged at an angle, the shooting blind area of the imaging device can be minimized to achieve a comprehensive observation of a large scene.

[0088] The foregoing are only the preferred embodiments of the present application and are not intended to limit the present application.
