Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a camera device and a recording and broadcasting device. Background Technology

[0002] The camera device has video recording capabilities and can achieve multi-directional shooting needs by adjusting the camera's shooting angle. For example, the camera device can be used to track the teacher's movement in real time and record teaching content.

[0003] To enable the camera to rotate in two different directions, camera devices in related technologies typically require two independent drive motors to drive the camera to rotate in different directions. For example, one drive motor drives the camera to rotate in a first direction (such as the horizontal direction), while another drive motor drives the camera to rotate in a second direction (such as the vertical direction).

[0004] However, the camera device requires multiple drive motors to drive the camera to rotate in multiple directions, which makes the material cost of the camera device high. Summary of the Invention

[0005] This application provides a camera device and a recording and broadcasting equipment, which can drive the camera to rotate in multiple directions with a single driving component, thereby reducing the material cost of the camera device.

[0006] In a first aspect, embodiments of this application provide a camera device, which includes a housing, a support member, a driving member, a first transmission assembly, and a second transmission assembly. The support member is rotatably connected to the housing. A camera is rotatably mounted on the support member. The driving member is mounted on the support member. The first transmission assembly is driveably connected to the driving member and the support member. The second transmission assembly is driveably connected between the first transmission assembly and the camera, or the drive connection between the first transmission assembly and the camera can be disconnected. When the second transmission assembly is in drive cooperation with the first transmission assembly and the camera, the driving member is used to drive the camera to rotate relative to the housing in a first direction through the first transmission assembly, and also to drive the camera to rotate relative to the support member in a second direction through the second transmission assembly. When the second transmission assembly is disconnected, the driving member drives the camera to rotate relative to the housing in the first direction through the first transmission assembly. The first direction and the second direction are set at an angle.

[0007] Based on the camera device provided in this application, compared to camera devices in related technologies, when the second transmission component is in transmission cooperation with the first transmission component and the camera, the camera can rotate relative to the housing in both a first and a second direction. When the second transmission component is disconnected, the camera can rotate relative to the housing in the first direction, thereby enabling a single driving component to drive the camera to rotate in multiple directions, which helps to reduce the material cost of the camera device. Furthermore, the camera can rotate simultaneously in both the first and second directions, allowing the camera to be adjusted or captured in two different directions at the same time, thus enabling the camera device to adjust or capture images from multiple perspectives. Moreover, when the camera device is in use, unlike camera devices in related technologies where multiple driving components are in standby mode, the camera device of this application avoids the energy waste caused by redundant driving components being idle for extended periods.

[0008] In some embodiments, the second transmission assembly includes a telescopic member and a first transmission wheel, a second transmission wheel, and a third transmission wheel arranged sequentially. The telescopic member is disposed on a support member; the first transmission wheel is throttlely connected to the first transmission assembly, the second transmission wheel is rotatably connected to the telescopic member, and the third transmission wheel is connected to the camera; wherein the second transmission wheel is configured to move relative to the support member under the drive of the telescopic member, to have a first position throttlely connected to the first transmission wheel and the third transmission wheel, and a second position separated from at least one of the first transmission wheel and the third transmission wheel.

[0009] Based on the above implementation, the camera device, under the action of the telescopic component, controls the selective connection of the second transmission wheel, allowing the second transmission wheel to flexibly switch between the first and third transmission wheels. Furthermore, the telescopic component enables the second transmission assembly to operate in different states. Users can select different transmission paths according to actual needs, and the telescopic component allows users to achieve complex transmission control through simple operations (such as moving the telescopic component). For example, when it is necessary to manually adjust the camera's rotation around a second direction, the user only needs to move the telescopic component to complete the switching of the transmission path, without the need for complex mechanical adjustments.

[0010] In some embodiments, the telescopic component includes a first magnetic attractor and a second magnetic attractor. The first magnetic attractor is disposed on the support member; the second magnetic attractor is slidably connected to the support member and magnetically engages with the first magnetic attractor. A second transmission wheel is rotatably connected to the second magnetic attractor. Specifically, the first magnetic attractor, through magnetic attraction with the second magnetic attractor, drives the second magnetic attractor to slide towards the first magnetic attractor, thereby moving the second transmission wheel to a first position; the first magnetic attractor, through magnetic repulsion with the second magnetic attractor, drives the second magnetic attractor to move away from the first magnetic attractor, thereby moving the second transmission wheel to a second position.

[0011] Based on the above embodiments, the camera device can flexibly switch the second transmission wheel between different positions through the mutual magnetic attraction or repulsion of the first and second magnetic components. When the first magnetic component attracts the second magnetic component, the second transmission wheel can connect to both the first and third transmission wheels simultaneously, achieving power transmission. Conversely, when the first magnetic component repels the second magnetic component, the second transmission wheel can separate from either the first or third transmission wheel, interrupting power transmission, thus facilitating the transmission and interruption of power in the second transmission assembly. Furthermore, the first magnetic component, fixed to the support member, provides a fixed reference point, allowing the camera device to more precisely control the position of the second magnetic component, thereby achieving precise control over the connection state of the second transmission wheel. Moreover, the magnetic attraction and repulsion mechanism of the telescopic component allows the second transmission assembly to operate in different working modes. Users can select different transmission paths according to actual needs, thereby achieving more diverse and complex shooting tasks. For example, when a rapid adjustment of the camera angle is required, the transmission path of the second transmission assembly can be quickly changed by altering the state of the telescopic component, achieving efficient positioning and adjustment of the camera.

[0012] In some embodiments, the support member is provided with a mounting through hole that extends along the sliding path of the second magnetic member; the second transmission wheel is provided with a connecting shaft, one end of which is connected to the second transmission wheel, and the other end of which passes through the mounting through hole and is rotatably connected to the second magnetic member.

[0013] Based on the above implementation, the direction of the extension path of the mounting through hole is roughly the same as the sliding path of the second magnetic chuck, so that the mounting through hole has a guiding function, thereby enabling the second magnetic chuck to drive the connecting shaft to move more smoothly, and also helping to reduce the risk of interference between the second transmission component and other components.

[0014] In some embodiments, the second magnetic member is provided with a first sliding portion; the support member is provided with a second sliding portion, and the second sliding portion slides in conjunction with the first sliding portion; wherein, both the first sliding portion and the second sliding portion extend along the sliding path of the second magnetic member.

[0015] Based on the above embodiments, the sliding engagement of the first sliding portion and the second sliding portion allows the second magnetic member to move smoothly on the support member, which helps to reduce friction and wear between the second magnetic member and the support member. Furthermore, the sliding engagement of the first sliding portion and the second sliding portion provides guidance for the movement of the second magnetic member, enabling it to move precisely along the sliding path.

[0016] In some implementations, the first drive wheel, the second drive wheel, and the third drive wheel are all rollers or gears.

[0017] Based on the above embodiments, power is transmitted between two adjacent rollers through friction between their contact surfaces, and the contact between the two adjacent rollers is continuous, resulting in a relatively smooth power transmission between them. Alternatively, two adjacent gears have a large contact area when meshing, which helps the second transmission component to transmit a larger torque.

[0018] In some embodiments, the first, second, and third transmission wheels are all rollers, and each of the outer peripheral surfaces of the first, second, and third transmission wheels is provided with a friction structure. When the second transmission wheel is in a first position, the friction structure on the outer peripheral surface of the second transmission wheel is in contact with both the friction structure on the outer peripheral surface of the first and third transmission wheels. When the second transmission wheel is in a second position, the friction structure on the outer peripheral surface of the second transmission wheel is separated from at least one of the friction structures on the outer peripheral surfaces of the first and third transmission wheels.

[0019] Based on the above embodiments, the friction structure helps increase the contact friction between the first, second, and third transmission wheels, making power transmission between them more efficient and thus helping to reduce slippage. Furthermore, the higher friction between the first, second, and third transmission wheels helps reduce energy loss caused by slippage, thereby improving the transmission efficiency of the first transmission assembly.

[0020] In some embodiments, the first transmission assembly includes a worm and a worm wheel, with the two ends of the worm fixedly connected to a drive member and a first transmission wheel, respectively; the worm wheel is connected to the housing and meshes with the worm; the support member is rotatably connected to the housing via the worm wheel; and the drive member is used to drive the support member and the camera to rotate relative to the housing in a first direction through the meshing connection of the worm and the worm wheel.

[0021] Based on the above implementation method, the mechanical contact between the worm gear and the worm provides stable power transmission, avoiding slippage in the first transmission component and ensuring good continuity and reliability of power transmission. Furthermore, the worm gear and worm transmission has a self-locking characteristic, which helps reduce the risk of accidental camera movement due to external forces.

[0022] In some embodiments, the camera device further includes a detection sensor, the camera having a detection position located on the path of the camera rotating about a second direction, the detection sensor being able to identify the camera at the detection position when the camera rotates to the detection position.

[0023] Based on the above implementation, the detection sensor can identify when the camera rotates to a specific detection position, ensuring that the camera can accurately position itself to the preset location. The detection sensor can provide real-time position feedback, allowing the camera device's controller to instantly control the drive components to adjust the camera's position, ensuring the camera is always in the correct posture and angle. Furthermore, the camera device can use the detection sensor to confirm whether the camera has reached the designated position, helping to prevent misoperation due to mechanical errors or other factors, thereby improving the reliability and stability of the camera device and reducing image quality problems caused by positional deviations. Moreover, the position information provided by the detection sensor can help the camera device perform self-calibration, ensuring that the camera accurately returns to the preset position each time it is used, avoiding cumulative errors that may occur during long-term use.

[0024] In some embodiments, the camera device further includes a first stop structure and a second stop structure, which are disposed on the support member. The camera has a first limit position and a second limit position, which are located on the path of the camera rotating about a second direction. When the camera rotates to the first limit position, the camera engages with the first stop structure. When the camera rotates to the second stop position, the camera engages with the second stop structure.

[0025] Based on the above embodiments, the first stop structure and the second stop structure can prevent the camera from rotating excessively, allowing the camera to rotate within an effective range. Furthermore, the first stop structure and the second stop structure provide clearly defined physical limit points, ensuring that the camera can accurately stop at the preset first and second limit positions. Moreover, the precise limit points provided by the first and second stop structures allow the camera device to perform self-calibration each time it is used, reducing the cumulative errors that may occur during long-term use.

[0026] In some embodiments, one of the camera and the support is provided with a rotating column, and the other of the camera and the support is provided with a rotating hole, which is rotatably disposed within the rotating hole; the rotating column and the rotating hole are interference-fitted; or, the outer periphery of the rotating column is provided with a damping sleeve, which abuts against the outer periphery of the rotating column and the inner wall of the rotating hole.

[0027] Based on the above implementation, by interfering with the rotating column and the rotating hole; or by providing a damping sleeve on the outer periphery of the rotating column, the risk of the camera rotating around the second direction due to its own weight is reduced, thereby making the camera require external force to rotate around the second direction relative to the support member.

[0028] Secondly, this application also provides a recording and broadcasting device, which includes a support frame and a camera device of any of the above embodiments, the camera device being disposed on the support frame.

[0029] Based on the above implementation method, the camera device can obtain a better shooting angle and field of view, which helps to reduce the obstruction of the camera device by obstacles. Attached Figure Description

[0041] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0042] 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.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] The camera device has video recording capabilities and can achieve multi-directional shooting needs by adjusting the camera's shooting angle. For example, the camera device can be used to track the teacher's movement in real time and record teaching content.

[0047] The inventors discovered that in order to achieve camera rotation in two different directions, camera devices in related technologies typically require two independent drive motors to drive the camera to rotate in different directions. For example, one drive motor drives the camera to rotate in a first direction (such as the horizontal direction), while another drive motor drives the camera to rotate in a second direction (such as the vertical direction). This results in the camera device requiring multiple drive motors to drive the camera to rotate in multiple directions, leading to higher material costs for the camera device.

[0048] In view of this, please refer to Figures 1 to 3 This application provides a camera device 10, which may include a housing 100, a support member 200, a camera 300, a first transmission assembly 500, a second transmission assembly 600, and a drive member 400. The support member 200 is rotatably connected to the housing 100; the camera 300 is rotatably mounted on the support member 200; the drive member 400 is mounted on the support member 200; the first transmission assembly 500 is driveably connected to the drive member 400 and the support member 200; the second transmission assembly 600 is driveably connected between the first transmission assembly 500 and the camera 300, or can be disconnected from the first transmission assembly 500 and the camera. The transmission connection between the heads 300; wherein, when the second transmission assembly 600 is in transmission cooperation with the first transmission assembly 500 and the camera 300, the driving member 400 is used to drive the camera 300 to rotate relative to the housing 100 about the first direction Y through the first transmission assembly 500, and at the same time, to drive the camera 300 to rotate relative to the support member 200 about the second direction X through the second transmission assembly 600; when the second transmission assembly 600 is in the disengaged state, the driving member 400 drives the camera 300 to rotate relative to the housing 100 about the first direction Y through the first transmission assembly 500; the first direction Y and the second direction X are set at an angle.

[0049] Thus, compared to the camera devices in related technologies, when the second transmission component 600 is in transmission cooperation with the first transmission component 500 and the camera 300, the camera 300 can rotate relative to the housing 100 around the first direction Y and around the second direction X. When the second transmission component 600 is in the disconnected state, the camera 300 can rotate relative to the housing 100 around the first direction Y, so that a single driving component 400 can drive the camera 300 to rotate around multiple directions, thereby helping to reduce the material cost of the camera device 10.

[0050] In addition, the camera 300 can rotate simultaneously around the first direction Y and around the second direction X, so that the camera 300 can be adjusted or shot in two different directions at the same time, thereby enabling the camera device 10 to adjust or shoot from multiple perspectives.

[0051] Moreover, when the camera device 10 is in use, unlike the multiple drive units 400 of the camera device 10 in the related art which are all in standby mode, the camera device 10 of this application can avoid the waste of energy caused by the redundant drive units 400 being in standby mode for a long time.

[0052] In some embodiments, when the drive member 400 is activated, the drive member 400 can transmit power to the first transmission assembly 500 and the support member 200, causing the support member 200 to rotate around the first direction Y, thereby enabling the camera 300 disposed on the support member 200 to also rotate around the first direction Y with the support member 200.

[0053] In some embodiments, when the second transmission component 600 is in transmission cooperation with the first transmission component 500 and the camera 300, the second transmission component 600 is directly connected to the first transmission component 500 and the camera 300. When the drive component 400 is activated, the drive component 400 can transmit power to the first transmission component 500, the second transmission component 600 and the camera 300, so that the camera 300 can rotate around the first direction Y and around the second direction X. When the second transmission component 600 disconnects the transmission connection between the first transmission component 500 and the camera 300, the second transmission component 600 is separated from at least one of the first transmission component 500 and the camera 300, so that the drive component 400 cannot transmit power to the first transmission component 500.

[0054] In some embodiments, the angle between the first direction Y and the second direction X can be set according to actual conditions and is not limited here. The first direction Y can be a vertical direction, and the second direction X can be a horizontal direction. In other embodiments, the first direction Y can be the height direction of the housing 100, and the second direction X can be the length direction of the housing 100.

[0055] The overall shape of the housing 100 can be roughly cubic or cuboid. The support member 200, camera 300, first transmission component 500, second transmission component 600, and drive component 400 can all be disposed inside the housing 100, so that the housing 100 can serve as a support structure and effectively protect the support member 200, camera 300, first transmission component 500, second transmission component 600, and drive component 400 from the influence of the external environment (such as dust, moisture, or physical impact).

[0056] The housing 100 is typically made of high-strength, lightweight materials, such as aluminum alloy and engineering plastics, which ensures sufficient strength while reducing the weight of the camera device 10.

[0057] In some embodiments, the drive element 400 is a device capable of converting electrical energy into mechanical energy. For example, the drive element 400 may be an electric motor.

[0058] Please see Figures 3 to 5 In some embodiments, the second transmission assembly 600 may include a telescopic member 610, a first transmission wheel 620, a second transmission wheel 630, and a third transmission wheel 640. The telescopic member 610 is disposed on the support member 200. The first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 may be arranged sequentially, with the first transmission wheel 620 being throttle-connected to the first transmission assembly 500, the second transmission wheel 630 being rotatably connected to the telescopic member 610, and the third transmission wheel 640 being connected to the camera 300. The second transmission wheel 630 is configured to move relative to the support member 200 under the drive of the telescopic member 610, having a first position throttle-connected to the first transmission wheel 620 and the third transmission wheel 640, and a second position separated from at least one of the first transmission wheel 620 and the third transmission wheel 640.

[0059] The telescopic component 610 allows for a change in the displacement of the second transmission wheel 630. The second transmission wheel 630 can be rotatably connected to the telescopic component 610 via a bearing or bushing. When the second transmission wheel 630 is driven to the first position by the telescopic component 610, it is driveably connected between the first transmission wheel 620 and the third transmission wheel 640. When the second transmission wheel 630 is driven to the second position by the telescopic component 610, it separates from at least one of the first transmission wheel 620 and the third transmission wheel 640, wherein the second transmission wheel 630 separates from the first transmission wheel 620; or, the second transmission wheel 630 separates from the third transmission wheel 640; or, the second transmission wheel 630 separates from both the first transmission wheel 620 and the third transmission wheel 640 simultaneously.

[0060] Thus, the camera device 10 can control the selective connection of the second transmission wheel 630 under the action of the telescopic component 610, so that the second transmission wheel 630 can flexibly switch between the first transmission wheel 620 and the third transmission wheel 640.

[0061] Furthermore, the telescopic component 610 allows the second transmission assembly 600 to operate in different states. Users can select different transmission paths according to their actual needs.

[0062] Furthermore, the telescopic component 610 allows users to achieve complex transmission control through simple operations (such as moving the telescopic component 610). For example, when it is necessary to manually adjust the camera 300 to rotate around the second direction Y, the user only needs to move the telescopic component 610 to complete the switching of the transmission path, without the need for complex mechanical adjustments.

[0063] Please see Figure 4 and Figure 5 In some embodiments, the telescopic component 610 may include a first magnetic chuck 611 and a second magnetic chuck 612. The first magnetic chuck 611 may be disposed on the support member 200, and the second magnetic chuck 612 may be slidably connected to the support member 200. The second magnetic chuck 612 and the first magnetic chuck 611 are magnetically engaged, and the second drive wheel 630 is rotatably connected to the second magnetic chuck 612. Specifically, the first magnetic chuck 611 drives the second magnetic chuck 612 to slide closer to the first magnetic chuck 611 by magnetic attraction, thereby moving the second drive wheel 630 to a first position; the first magnetic chuck 611 drives the second magnetic chuck 612 to move away from the first magnetic chuck 611 by magnetic repulsion, thereby moving the second drive wheel 630 to a second position.

[0064] Because the second magnetic member 612 can magnetically engage with the first magnetic member 611, the telescopic member 610 can selectively be in a magnetic attraction state or a repulsion state. When the telescopic member 610 is in the magnetic attraction state, the first magnetic member 611 and the second magnetic member 612 are magnetically attracted to each other. When the telescopic member 610 is in the repulsion state, the first magnetic member 611 and the second magnetic member 612 are magnetically repelled.

[0065] When the telescopic component 610 is in a magnetic attraction state, the second magnetic member 612 moves toward the first magnetic member 611 to drive the second transmission wheel 630 to be connected to the first transmission wheel 620 and the third transmission wheel 640; when the telescopic component 610 is in a repulsive state, the second magnetic member 612 moves away from the first magnetic member 611 and drives the second transmission wheel 630 to separate from at least one of the first transmission wheel 620 and the third transmission wheel 640.

[0066] When the telescopic component 610 is in a magnetic attraction state, the first magnetic component 611 attracts the second magnetic component 612 to move. The second magnetic component 612 moves along a preset route to a position adjacent to the first magnetic component 611, thereby driving the second transmission wheel 630 to a first position. This allows the second magnetic component 612 to drive the second transmission wheel 630 into close contact with the first transmission wheel 620 and the third transmission wheel 640, forming a complete transmission path. The driving component 400 transmits power from the first transmission assembly 500 to the first transmission wheel 620, and then from the first transmission wheel 620 to the second transmission wheel 630, and then to the third transmission wheel 640, ultimately driving the camera 300 to rotate around the second direction X.

[0067] When the telescopic component 610 is in a repelled state, the first magnetic component 611 repels the second magnetic component 612. The second magnetic component 612 moves along a preset path to a position away from the first magnetic component 611, and drives the second transmission component 630 to a second position. This causes the second magnetic component 612 to drive the second transmission wheel 630 to separate from the first transmission wheel 620 or the third transmission wheel 640, interrupting the power transmission. The camera 300 cannot obtain power through the first transmission wheel 620, preventing the camera device 10 from driving the camera 300 to rotate around the second direction X through the second transmission component 600.

[0068] Thus, the camera device 10 can flexibly switch the second transmission wheel 630 between different positions through the mutual magnetic attraction or repulsion of the first magnetic member 611 and the second magnetic member 612. When the first magnetic member 611 attracts the second magnetic member 612, the second transmission wheel 630 can be connected to both the first transmission wheel 620 and the third transmission wheel 640 simultaneously, realizing power transmission. When the first magnetic member 611 repels the second magnetic member 612, the second transmission wheel 630 can separate from either the first transmission wheel 620 or the third transmission wheel 640, interrupting power transmission, thereby facilitating the transmission and interruption of power in the second transmission assembly 600.

[0069] In addition, the first magnetic 611 is fixed on the support 200, providing a fixed reference point, which allows the camera device 10 to more accurately control the position of the second magnetic 612, thereby achieving precise control over the connection state of the second transmission wheel 630.

[0070] Furthermore, the magnetic attraction and repulsion mechanism of the telescopic component 610 allows the second transmission component 600 to operate in different working modes. Users can select different transmission paths according to actual needs, thereby achieving more diverse and complex shooting tasks. For example, when it is necessary to quickly adjust the angle of the camera 300, the transmission path of the second transmission component 600 can be quickly changed by changing the state of the telescopic component 610, achieving efficient positioning and adjustment of the camera 300.

[0071] In some embodiments, the telescopic component 610 may include a telescopic rod, one end of which is fixedly connected to the support member 200, and the other end of which is rotatably connected to the second drive wheel 630. When the telescopic rod is in the retracted state, it drives the second drive wheel 630 to a first position. When the telescopic rod is in the extended state, it drives the second drive wheel 630 to a second position, thereby facilitating the switching of the second drive wheel 630 between the first and second positions.

[0072] In some embodiments, the first magnetic attractor 611 can be an electromagnet, which can be made of a high-permeability material (such as an iron core). A coil is wound around the outside of the electromagnet, and the camera device 10 can change the polarity of the electromagnet by controlling the direction of the current flowing through the coil. The second magnetic attractor 612 can be a permanent magnet, such as a neodymium iron boron magnet, which has high magnetic strength and stability. The second magnetic attractor 612 is mounted on the support member 200 via a slide rail or groove, allowing the second magnetic attractor 612 to slide freely along a predetermined path.

[0073] When the first magnetic attractor 611 is energized and generates a magnetic field with the same polarity as the second magnetic attractor 612, the two attract each other. At this time, the second magnetic attractor 612 moves along the slide rail to a position aligned with the first magnetic attractor 611. In the attracted state, the second transmission wheel 630 is in close contact with the first transmission wheel 620 and the third transmission wheel 640, forming a complete transmission path. Power is transmitted from the first transmission wheel 620 to the second transmission wheel 630, and then to the third transmission wheel 640, ultimately driving the camera 300 to rotate around the second direction X. When the first magnetic attractor 611 is energized and generates a magnetic field with the opposite polarity to the second magnetic attractor 612, the two repel each other. At this time, the second magnetic attractor 612 moves along the slide rail to a position away from the electromagnet. In the repelling state, the second transmission wheel 630 separates from the first transmission wheel 620 or the third transmission wheel 640, interrupting the power transmission.

[0074] In some embodiments, the second magnetic attractor 612 can be slidably disposed on the support member 200. The second magnetic attractor 612 can be an electromagnet, which can be made of a high-permeability material (such as an iron core). A coil is wound around the outside of the electromagnet, and the camera device 10 can change the polarity of the electromagnet by controlling the direction of the current flowing through the coil. The first magnetic attractor 611 is fixedly disposed on the support member 200. The first magnetic attractor 611 can be a permanent magnet, such as a neodymium iron boron magnet, which has high magnetic strength and stability. The second magnetic attractor 612 is mounted on the support member 200 via a slide rail or slide groove, allowing the second magnetic attractor 612 to slide freely along a predetermined path.

[0075] When the second magnetic chuck 612 is energized and generates a magnetic field with the same polarity as the first magnetic chuck 611, the two attract each other. At this time, the second magnetic chuck 612 moves along the slide rail to a position aligned with the first magnetic chuck 611. In the attracted state, the second magnetic chuck 612 drives the second transmission wheel 630 into close contact with the first transmission wheel 620 and the third transmission wheel 640, forming a complete transmission path. Power is transmitted from the first transmission wheel 620 to the second transmission wheel 630, and then to the third transmission wheel 640, ultimately driving the camera 300 to rotate around the second direction X. When the second magnetic chuck 612 is energized and generates a magnetic field with the opposite polarity to the first magnetic chuck 611, the two repel each other. At this time, the second magnetic chuck 612 moves along the slide rail to a position away from the electromagnet. In the repelling state, the second magnetic chuck 612 drives the second transmission wheel 630 to separate from the first transmission wheel 620 or the third transmission wheel 640, interrupting the power transmission.

[0076] Please see Figure 6 and Figure 8 In some embodiments, the support member 200 is provided with a mounting through hole 210, which extends along the sliding path of the second magnetic member 612. The second drive wheel 630 is provided with a connecting shaft 631, one end of which is connected to the second drive wheel 630, and the other end of which passes through the mounting through hole 210 and is rotatably connected to the second magnetic member 612. Thus, the direction of the extension path of the mounting through hole 210 is approximately the same as the sliding path of the second magnetic member 612, giving the mounting through hole 210 a guiding function. This allows the second magnetic member 612 to smoothly drive the connecting shaft 631, and also helps reduce the risk of interference between the second drive wheel 630 and other components.

[0077] Please see Figure 5 and Figure 8 In some embodiments, the second magnetic member 612 may have a first sliding portion 613, and the support member 200 may have a second sliding portion 220, with the second sliding portion 220 slidingly engaging with the first sliding portion 613; wherein both the first sliding portion 613 and the second sliding portion 220 extend along the sliding path of the second magnetic member 612. Thus, the sliding engagement of the first sliding portion 613 and the second sliding portion 220 allows the second magnetic member 612 to move smoothly on the support member 200, helping to reduce friction and wear between the second magnetic member 612 and the support member 200.

[0078] Furthermore, the sliding engagement of the first sliding part 613 and the second sliding part 220 provides guidance for the movement of the second magnetic member 612, enabling the second magnetic member 612 to move precisely along the sliding path.

[0079] There are several options for the sliding engagement of the first sliding part 613 and the second sliding part 220. For example, the first sliding part 613 can be a slider, and the second sliding part 220 can be a slide rail or a slide groove. Alternatively, the first sliding part 613 can be a slide rail or a slide groove, and the second sliding part 220 can be a slider, which helps to achieve the sliding engagement of the first sliding part 613 and the second sliding part 220.

[0080] Please see Figure 4 In some embodiments, the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 are all rollers. When the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 come into contact sequentially, adjacent rollers transmit power through the friction between their contact surfaces, and the contact between adjacent rollers is continuous, resulting in a relatively smooth power transmission between adjacent rollers.

[0081] In addition, the transmission between two adjacent rollers is a friction transmission, which makes the speed change a gradual process rather than a sudden jump, thus helping to reduce mechanical vibration and noise.

[0082] In this embodiment, the outer peripheral surfaces of the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 are all provided with friction structures. The outer peripheral surfaces are the contact surfaces of two adjacent transmission wheels. Specifically, when the second transmission wheel is in the first position, the friction structure on the outer peripheral surface of the second transmission wheel is in contact with both the friction structures on the outer peripheral surfaces of the first and third transmission wheels; when the second transmission wheel is in the second position, the friction structure on the outer peripheral surface of the second transmission wheel is separated from at least one of the friction structures on the outer peripheral surfaces of the first and third transmission wheels.

[0083] Thus, when the second transmission wheel 630 is in the first position, the friction structure helps increase the contact friction between the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640, making the power transmission between them more efficient and thus helping to reduce slippage. Furthermore, the greater friction between the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 helps reduce energy loss caused by slippage, thereby improving the transmission efficiency of the first transmission assembly 500.

[0084] In some embodiments, the friction structure can be a friction pattern provided on the outer peripheral surface of the roller. For example, the friction structure refers to lines or grooves provided along the circumference of the roller, or lines or grooves provided along the axial direction of the roller. Alternatively, the friction structure can be a silicone sleeve or rubber sleeve provided on the outer peripheral surface of the outer wheel.

[0085] In some embodiments, the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 are all gears. When the first transmission wheel 620, the second transmission wheel 630, and the third transmission wheel 640 mesh sequentially, adjacent gears have a large contact area during meshing, which helps the second transmission assembly 600 to transmit a larger torque.

[0086] In addition, the large contact area between two adjacent gears when they mesh helps to enhance the load-bearing capacity of the gears under high load conditions, thereby enabling the first transmission component 500 to effectively absorb and disperse mechanical shocks, and thus enabling the camera device 10 to operate stably in harsh working environments.

[0087] Please see Figure 4 and Figure 6 In some embodiments, the first transmission assembly 500 includes a worm gear 510, with both ends of the worm gear 510 fixedly connected to the drive member 400 and the first transmission wheel 620, respectively. One end of the worm gear 510 is fixedly connected to the output shaft of the drive member 400, and the other end of the worm gear 510 is fixedly connected to the first transmission wheel 620, allowing the drive member 400 to transmit power to the first transmission assembly 500 via the worm gear 510.

[0088] The first transmission assembly 500 may further include a worm gear 520, which is connected to the housing 100. The worm gear 520 can mesh with the worm 510, and the support member 200 is rotatably connected to the housing 100 via the worm gear 520. The drive member 400 is used to drive the support member 200 and the camera 300 to rotate relative to the housing 100 about a first direction Y through the meshing connection of the worm 510 and the worm gear 520. The worm gear 520 can be fixedly connected to the housing 100 by means of screws or riveting, and the support member 200 can be rotatably connected to the worm gear 520 by bearings or bushings.

[0089] In this embodiment, when the drive unit 400 is activated, the output shaft of the drive unit 400 drives the worm 510 to rotate. Due to the tight meshing between the worm wheel 520 and the worm 510, the worm 510 and the drive unit 400 are disposed on the support member 200. The support member 200 is rotatably connected to the worm wheel 520, and the worm wheel 520 is fixedly connected to the housing 100. This allows the helical teeth of the worm 510 to move along the tooth arrangement direction of the worm wheel 520, causing the worm 510 to rotate around the circumference of the worm wheel 520. Consequently, the support member 200 can rotate together with the worm 510 and the drive unit 400, thereby causing the support member 200 and the camera 300 disposed on the support member 200 to rotate around the first direction Y.

[0090] Furthermore, the mechanical contact between the worm gear 520 and the worm 510 provides stable power transmission, preventing slippage in the first transmission assembly 500 and ensuring good continuity and reliability in power transmission. Moreover, the transmission between the worm gear 520 and the worm 510 has a self-locking characteristic, which helps reduce the risk of accidental movement of the camera 300 due to external forces.

[0091] Please see Figure 3 In some embodiments, the camera device 10 further includes a detection sensor 700, and the camera 300 has a detection position located on the path of the camera 300 rotating about a first direction Y. When the camera 300 rotates to the detection position, the detection sensor 700 can identify the camera 300 located at the detection position.

[0092] The detection sensor 700 can be of various types; for example, it can be a Hall effect sensor. The detection sensor 700 can be mounted on the support 200, and the camera 300 can be equipped with a magnet. When the camera 300 rotates around the second direction X, the distance between the magnet and the detection sensor 700 changes, and the magnetic field detected by the detection sensor 700 also changes. The detection sensor 700 uses this change in magnetic field to detect the presence of the camera 300. When a magnet approaches the detection sensor 700, the change in magnetic field is detected by the detection sensor 700, generating a corresponding electrical signal, thereby enabling the detection sensor 700 to determine the position of the camera 300.

[0093] For example, the detection sensor 700 can be an ultrasonic sensor, which can be mounted on the support 200. The ultrasonic sensor measures distance by emitting ultrasonic waves toward the camera 300 and detecting the time it takes for the waves to reflect back from the camera 300. When the camera 300 approaches the detection sensor 700, the time it takes for the reflected ultrasonic waves to travel is shortened. The sensor generates a signal based on this time difference, thereby enabling the detection sensor 700 to determine the position of the camera 300.

[0094] Thus, the detection sensor 700 can identify when the camera 300 rotates to a specific detection position, ensuring that the camera 300 can be accurately positioned at the preset position. The detection sensor 700 can provide real-time position feedback, enabling the controller of the camera device 10 to instantly control the drive component 400 to adjust the position of the camera 300, thereby ensuring that the camera 300 is always in the correct posture and angle.

[0095] In addition, the camera device 10 can confirm whether the camera 300 has reached the designated position by the detection sensor 700, which helps to prevent misoperation caused by mechanical errors or other factors, thereby helping to improve the reliability and stability of the camera device 10, and also helps to reduce shooting quality problems caused by position deviation of the camera device 10.

[0096] Moreover, the position information provided by the detection sensor 700 can help the camera device 10 perform self-calibration, ensuring that the camera 300 can accurately return to the preset position every time it is used, thus avoiding the cumulative errors that may occur during long-term use.

[0097] In some embodiments, the camera device 10 further includes a first stop structure (not shown) and a second stop structure (not shown). The first stop structure and the second stop structure are disposed on the support member 200. The camera 300 has a first limit position and a second limit position. The first limit position and the second limit position are located on the path of the camera 300 rotating around the second direction X. When the camera 300 rotates to the first limit position, the camera 300 is stopped by the first stop structure. When the camera 300 rotates to the second stop position, the camera 300 is stopped by the second stop structure.

[0098] The first and second extreme positions are both the end positions of the path through which the camera 300 rotates around the second direction X, allowing the camera 300 to rotate within a certain range, so that the user can effectively adjust the camera device 10.

[0099] The first stop structure can be a stop plate or a stop block, and it can be disposed on the support member 200. The first stop can limit the maximum clockwise angle of rotation of the camera 300 around the second direction X. When the camera 300 moves to the first limit position, the first stop structure can prevent the camera 300 from continuing to rotate.

[0100] The second stop structure can be a stop plate or a stop block, and it can be disposed on the support member 200. The second stop can limit the maximum counterclockwise angle of rotation of the camera 300 around the second direction X. When the camera 300 moves to the second limit position, the second stop structure can prevent the camera 300 from continuing to rotate.

[0101] Thus, the first and second stop structures prevent the camera 300 from rotating excessively, allowing it to rotate within an effective range. Furthermore, the first and second stop structures provide clearly defined physical limit points, ensuring the camera 300 can accurately stop at the preset first and second limit positions. Moreover, the precise limit points provided by the first and second stop structures enable the camera device 10 to self-calibrate each time it is used, reducing potential cumulative errors during long-term use.

[0102] Please see Figure 3 In some embodiments, the detection sensor 700 may be an optical sensor, such as an optical encoder. The camera 300 may be provided with a shield 310, which can block the light emitted by the detection sensor 700 when the camera 300 moves to an extreme position (e.g., a first extreme position or a second extreme position), so that the detection sensor 700 can identify that the camera 300 has moved to the extreme position.

[0103] Please see Figures 6 to 8 In some embodiments, one of the camera 300 and the support member 200 is provided with a rotating column 810, and the other of the camera 300 and the support member 200 is provided with a rotating hole 820. The rotating hole 820 is rotatably disposed within the rotating hole 820, thereby facilitating the camera 300 to be rotatably disposed on the support member 200 around the second direction X.

[0104] In some embodiments, the rotating post 810 and the rotating hole 820 are interference-fitted, wherein the diameter of the rotating post 810 is slightly larger than the inner diameter of the rotating hole 820. When the rotating post 810 is assembled into the rotating hole 820, there is no obvious gap between the rotating post 810 and the inner wall of the rotating hole 820, resulting in a tight fit between them. This creates a certain clamping force at the contact point between the rotating post 810 and the inner wall of the rotating hole 820, thereby helping to reduce the risk of the camera 300 rotating around the second direction X due to its own weight. Consequently, the camera 300 requires external force to rotate relative to the support member 200 around the second direction X. Of course, there can be two rotating posts 810 and two rotating holes 820. For example, two rotating posts 810 can be arranged on opposite sides of the camera 300, with each rotating post 810 rotatingly engaged with one rotating hole 820.

[0105] A damping sleeve is provided on the outer periphery of the rotating column 810, and the damping sleeve abuts against the outer periphery of the rotating column 810 and the inner wall of the rotating hole 820. The damping sleeve can be a silicone damping sleeve or a rubber damping sleeve, etc. In this way, the damping sleeve can increase the friction between the rotating column 810 and the rotating hole 820, preventing the camera 300 assembly from easily rotating around the second direction X due to its own gravity. This helps improve the stability of the camera 300 on the support 200, and further helps reduce the risk of accidental rotation of the camera 300 due to slight vibrations or external interference.

[0106] Please see Figure 4 , Figure 6 and Figure 7 In some embodiments, the support member 200 includes a support frame 230 and a connecting frame 240 connected together, which together enclose a receiving space 250. The support member 200 has an opening 260 that can communicate with the receiving space 250. The drive member 400, worm gear 510, and worm wheel 520 can be located in the receiving space 250. The worm wheel 520 can pass through the opening 260 and be fixedly connected to the housing 100. The drive member 400 can be disposed on the connecting frame 240 or the support member 200. The second transmission assembly 600 can be disposed on the connecting frame 240. The camera 300 is rotatably connected to the connecting frame 240.

[0107] In some embodiments, the connecting frame 240 may include a first sub-support 241, a second sub-support 242, and a third sub-support 243, with the second sub-support 242 connected to the first sub-support 241 and the third sub-support 243. The first sub-support 241 is connected to the support frame 230 and together they enclose a receiving space 250. The camera 300 is rotatably connected between the third sub-support 243 and the second sub-support 242. The telescopic component 610, along with the first drive wheel 620, the second drive wheel 630, and the third drive wheel 640, are respectively disposed on opposite sides of the second sub-support 242, thereby helping to avoid interference between the telescopic component 610 and the first drive wheel 620, the second drive wheel 630, and the third drive wheel 640.

[0108] In some embodiments, the camera device 10 further includes a base 900, which is fixedly connected between the worm gear 520 and the housing 100 and spaced apart from the support frame 230, thereby preventing interference between the support member 200 and the base 900.

[0109] This application also proposes a recording and broadcasting device, which may include a support member 200 and a camera device 10 of any of the above embodiments. The camera device 10 may be disposed on the support frame 230. For example, the housing 100 of the camera device 10 may be connected to the support frame 230 by means of snap-fit ​​connection or threaded connection.

[0110] The recording equipment can set the camera device 10 in a suitable position on the support frame 230 according to the actual situation. The camera device 10 can be set on the top or side of the support frame 230, so that the camera device 10 can obtain a better shooting angle and field of view, which helps to reduce the obstruction of the camera device 10 by obstacles.

[0111] In some embodiments, the support frame 230 may be made of lightweight and durable materials, such as aluminum alloy or high-strength plastic, thereby giving the support frame 230 good stability.
