Description

Technical Field

[0001] This application relates to the field of video recorders, and more particularly to a lifting and tilting video recorder. Background Technology

[0002] Video recorders (or surveillance cameras) are widely used in homes, offices, and public places for real-time monitoring and recording. Traditional fixed video recorders are mostly installed on walls or ceilings, with limited monitoring angles and field of view, and cannot flexibly adjust the monitoring direction, easily creating blind spots. To expand the monitoring range, pan-tilt video recorders have appeared on the market, which can rotate left and right or up and down through a motor drive, but they still have the following shortcomings: First, the monitoring height is fixed, making it difficult to adapt to different installation environments and viewing angle requirements; second, the structure is complex and costly, and the multi-motor drive is prone to failure; third, manual adjustment lacks stable positioning and is prone to loosening and rebound; fourth, in low-light environments, external supplementary lighting equipment is often required, and lighting and camera adjustment are not integrated.

[0003] Chinese Patent Publication No. CN223106002U discloses a lighting device with camera function, including a lighting component, a camera device, and a connecting rod. The lighting component and the camera device are connected by a connecting rod with damping blocks. A first damping block is tightly attached to the outside of the connecting rod, and a second damping block is located between the camera device housing and a hinge block. The connecting rod has an irregular shape to match the irregular block inside the lighting component. A control circuit board is located at one end of the lighting component, electrically connected to the camera device, and connected to an external circuit via an external threaded connector. The advantages of this invention are: it combines camera and lighting functions, providing security protection. It can move vertically up and down, allowing users to easily adjust the camera's position within the lampshade, preventing the lampshade edges from obstructing the lens, and achieving omnidirectional, blind-spot-free monitoring of the surrounding environment. While this patent uses a connecting rod with damping blocks to connect the lighting component and the camera device and supports manual up-and-down movement and rotation, allowing for a certain range of monitoring and adjustment, both lifting and rotation rely on manual operation, making the adjustment process inconvenient. Furthermore, the damping structure is prone to wear after long-term use, leading to unstable positioning.

[0004] Chinese Patent Publication No. CN221977247U discloses an adjustable-angle lighting and video recording device, including a camera component and a light-emitting component. One end of the camera component is mounted below the light-emitting component via a connecting shaft, which can slide within the light-emitting component. The light-emitting component includes a lamp port, a power board, a heat-dissipating aluminum frame, and an LED aluminum-based lamp plate. One end of the lamp port is detachably connected to a power source, and the other end of the lamp port is equipped with a heat-dissipating aluminum frame. The LED aluminum-based lamp plate is arranged around the heat-dissipating aluminum frame, and the LED aluminum-based lamp plate is connected to the lamp port via the power board, which is located inside the heat-dissipating aluminum frame. The outer periphery of the connecting shaft is slidably connected to the inner ring of the heat-dissipating aluminum frame. This adjustable-angle lighting and video recording device is equipped with a light-emitting component and a stretchable camera component. The light-emitting component and the camera component can rotate as a whole by 340°, and the camera component can rotate vertically up to 50°. The lamp body has a built-in heat-dissipating aluminum frame, which effectively reduces the temperature of the LED aluminum-based lamp plate, thereby extending the lifespan of the LED chips. Although the patent has a certain adjustment range, it still requires manual operation by the user and cannot achieve remote or automatic adjustment, which limits its application scenarios. Furthermore, manual adjustment is prone to loosening after frequent use, affecting the stability of monitoring.

[0005] Therefore, existing manual adjustment methods suffer from problems such as inconvenient operation, low adjustment accuracy, easy wear and tear, and insufficient long-term stability. There is an urgent need for a lifting and oscillating video recorder that supports manual, electric, or automatic adjustment, has a stable structure, high integration, and reasonable cost. Utility Model Content

[0006] The technical problem this application aims to solve is that existing equipment relies on manual adjustment, resulting in inconvenience in operation, low precision, and a tendency to loosen after long-term use. To address these shortcomings of the prior art, this application provides a height-adjustable oscillating video recorder.

The gear set enables the second motor to rotate relative to the lifting column in a first direction when the second motor is working, thereby driving the rotating assembly and the camera assembly to rotate in the first direction.

[0010] Preferably, the gear set includes a first gear that rotates synchronously with the shaft of the second motor, and a second gear disposed below the lifting column. The second gear is coaxially disposed with the lifting column. The first gear meshes with the second gear.

A window is provided on the side of the lifting column corresponding to the threaded part. Multiple sets of hook blocks are provided on the inner wall of the lampshade corresponding to the window. The multiple sets of hook blocks are axially arranged in the lampshade. A gap is left between each two adjacent sets of hook blocks. When the threaded part rotates, it can engage or disengage with different hook blocks, thereby driving the lifting assembly to lift.

[0015] Preferably, the hook block is inclined to provide tension to the threaded part, so that the lifting assembly can be lifted and lowered smoothly. The upper and lower dimensions of the threaded part are smaller than the middle dimension. The third motor is not coaxial with the lifting column.

[0016] Preferably, the rotating assembly includes an upper bracket and a lower bracket, the lower ends of which form two sets of clamping arms.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this application. Obviously, the described embodiments are some embodiments of this application, but not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0040] A preferred embodiment of this application provides a height-adjustable oscillating video recorder; such as... Figures 1-2As shown, the device includes a lamp head assembly 1 and a light-emitting component 2 located below and connected to the lamp head assembly. A lifting component 3 is installed within the light-emitting component. The lifting component 3 is connected to a camera component 5 via a rotating component 4. The camera component 5 can rotate up and down within the rotating component 4, while the rotating component 4 can rotate left and right relative to the lifting component 3, thereby driving the camera component 5 to rotate in any direction (up, down, left, right). The lamp head assembly 1 includes a lamp head 11 with a threaded interface 10 on top. A power board 12 connected to the threaded interface is installed inside the lamp head. After mains power is connected through the threaded interface, it is transmitted to the power board, where it is stepped down to 5V. Simultaneously, the power board 12 is electrically connected to the light-emitting component 2 to power the light-emitting component for illumination; the power board is also connected to the camera component 5 to power the camera for monitoring. The light-emitting component 2 is located above the camera component 5. The light emitted by the light panel 22 is partially projected downwards and outwards through the light-transmitting lampshade 20 for ambient lighting; the other portion of the light shines directly downwards, providing effective supplementary lighting for the monitoring area of ​​the camera assembly 5 located directly below it, improving the imaging quality of the camera 51 in low-light environments. Since the light-emitting component 2 is also connected to a lifting component 3, the lifting component can move up and down relative to the light-emitting component, thereby raising and lowering the camera assembly to change its monitoring height. This, combined with the rotation component's left and right rotation, enables left-right rotation monitoring, while the camera assembly rotates up and down within the rotating component, achieving up-and-down rotation monitoring. This allows the recorder to monitor at any angle, and the monitoring height is adjustable, providing a wider monitoring range. It should be noted that the threaded interface can also be replaced with a socket or other form of mains power connection, with the socket connecting to the power board, which then steps down the mains voltage. Alternatively, the power board can be directly connected to the mains voltage and step down to power the camera motherboard and light panel assembly, enabling them to operate.

[0041] Specifically, such as Figures 1-4As shown, the light-emitting component 2 includes a lampshade 20, inside which a lamp plate fixing post 23 is provided. A gap 24 is left between the outer wall of the lamp plate fixing post 23 and the inner wall of the lampshade 20. The lamp plate 22 is installed on the outer wall of the lamp plate fixing post 23 and electrically connected to the power board 12. The power board supplies power to the lamp plate to make it emit light, and the light passes through the gap to illuminate the lampshade. Therefore, the lampshade should be made of a light-transmitting material. An upper opening 25 is provided above the gap 24. The lamp plate can be inserted into the gap through the upper opening and fixed to the outer wall of the lamp plate fixing post. The lamp plate can be selected as an FPC flexible board with a certain curvature. The lamp plate can adopt an existing FPC flexible board type lamp plate structure, which is not within the protection scope of this application. To prevent the connected lamp panel from rotating relative to the lamp panel fixing post, limit grooves 220 are provided on both the upper and lower sides of the lamp panel 22. A limit block 231 is provided at the lower end of the gap corresponding to the limit groove. When the lamp panel is fitted onto the outer wall of the lamp panel fixing post, rotating the lamp panel causes the limit block to engage in the limit groove. At this time, the lamp panel cannot rotate along the periphery of the lamp panel fixing post, thus fixing the lamp panel. The lamp cover 20 is fixedly connected to the lamp holder 11 via a mounting plate 21. The mounting plate can seal the upper opening to prevent the lamp panel from shaking up and down. Wiring holes are provided on the mounting plate 21 to facilitate the connection of the power board and the lamp panel.

[0042] Furthermore, such as Figures 2-8As shown, a lower opening 26 is provided below the lamp panel fixing column 23. The lifting assembly 3 is inserted into the lamp panel fixing column through the lower opening and contacts the inner wall of the lamp panel fixing column. The lifting assembly 3 includes a lifting column 30, on which two sets of abutment buckles 300 are provided. The lamp panel fixing column 23 is provided with a lifting groove 230 corresponding to the abutment buckles. When the lifting assembly is inserted into the lamp panel fixing column through the lower opening, the abutment buckles are placed in the lifting groove. Therefore, the upper end of the abutment buckle is a fixed end and the lower end is a movable end to prevent the lifting assembly from sliding out of the lifting groove during the descent. That is, the lifting groove can be used as a travel limit for the lifting assembly to rise and fall. To increase the friction between the lifting column 30 and the inner wall of the light panel fixing column 23, multiple sets of silicone rings 31 are fitted on the outer wall of the lifting column. These silicone rings increase the friction between the lifting column and the light panel fixing column. The lifting assembly can then be manually raised and lowered, with the friction generated by the silicone rings 31 fixing it at the lifting position. Therefore, the friction between the silicone rings and the inner wall of the light panel fixing column must be sufficiently large, exceeding the sum of the weights of the lifting assembly 3, the rotating assembly 4, and the camera assembly 5. Simultaneously, since the abutment buckle 300 is placed within the lifting groove 230, it also generates a certain abutment force with the light panel. When the monitoring height of the camera assembly needs to be adjusted, the camera assembly 5 can be pulled up and down. After pulling, the friction between the silicone rings and the inner wall of the light panel fixing column fixes it at the adjusted height. Furthermore, since the abutment buckle 300 can only slide within the lifting groove 230, it also prevents the lifting assembly from being pulled out of the light panel fixing column. It should be noted that the length of the lifting slot can be set as needed. In this application, there is no specific limitation on the height of the lifting slot 230. When the height of the lifting slot is smaller, the lifting stroke of the camera component is smaller, and its maximum descent height is more stable and will not cause shaking or is less likely to occur. However, when the height of the lifting slot is larger, the camera component is more likely to shake when it descends to a certain height.

[0043] Furthermore, such as Figure 2 and Figures 9-12As shown, the rotating assembly 4 consists of an upper rotating bracket 40 and a lower rotating bracket 41. Both the upper and lower rotating brackets are equipped with two sets of clamping arms 43. The camera assembly 5 is connected to the rotating assembly 4 via the clamping arms and can rotate up and down within the two sets of clamping arms. The upper rotating bracket 40 includes a connecting plate 42, with the two sets of clamping arms 43 positioned below the connecting plate. A connecting column 44 is positioned above the connecting plate, and an isolation plate 440 is installed inside the connecting column 44. The isolation plate divides the interior of the connecting column into an upper receiving cavity 441 and a lower receiving cavity 442. The second motor 45 is positioned in the lower receiving cavity, and the isolation plate 440 has a second motor shaft hole 444. The second motor shaft 450 passes through the second motor shaft hole and extends into the upper receiving cavity. A first gear 47 is fitted onto the portion of the second motor shaft positioned in the upper receiving cavity. A second gear 32, corresponding to the first gear, is provided inside the lifting column 30 and meshes with the first gear. When the second motor 45 operates, the second motor shaft rotates, driving the first gear to rotate. In this application, the second motor 45 is configured as an eccentric motor, meaning that the shaft of the second motor is not located at the central axis of the second motor, but rather offset from it. The purpose of using an eccentric motor is to reduce costs and eliminate the need for custom-made components, thus lowering the cost of the video recorder. Furthermore, the second gear is coaxially aligned with the lifting column. Through the meshing of the second gear 32 with the first gear 47, the central axis of the lifting column is aligned with the central axis of the second motor. This means that when the second motor drives its shaft to rotate, the first gear rotates synchronously with it. However, since the first and second gears are meshed, the second gear would normally rotate synchronously with the first gear. Because the second gear 32 is coaxially and fixedly connected to the lifting column 30, the lifting column 30 is confined within the lamp plate fixing column 23 by the engagement of the latch 300 and the lifting groove 230. Therefore, the lifting column 30 itself cannot rotate around its axis. Since the second gear 32 is coaxially and fixedly connected to the lifting column 30, the second gear 32 cannot rotate. When the second motor 45 operates, its shaft drives the first gear 47 to rotate. Since the first gear 47 meshes with the non-rotatable second gear 32, according to the principle of relative motion of gear meshing, the rotation of the first gear 47 will be converted into driving itself (along with the second motor 45 on which it is installed and the entire rotating assembly 4) to revolve around the fixed second gear 32 (i.e. the axis of the lifting column 30), thereby realizing the rotation of the rotating assembly 4 relative to the lifting assembly 3 in the left and right directions.In this application, the second motor 45 and the lifting column 30 are coaxially arranged, and the abutment buckle 300 and the lifting groove 230 prevent the lifting column from rotating. When the second motor is working, it drives the second motor shaft to rotate, which in turn drives the first gear 47 to rotate. Based on the relativity of rotation, the second gear cannot rotate, which means that the first gear rotates around the second gear as the center. Since the second motor and the lifting column are coaxial with the second gear, the second motor shaft rotates when the second motor is working, driving the second motor 45 to rotate around the lifting column shaft as the center. This achieves the rotation of the rotating component 4 and drives the camera component 5 to rotate left and right. It should be noted that in the field of video recorders, the camera component 5 does not need to rotate continuously; it only needs to rotate when the video recorder needs to rotate. Therefore, there is no need to consider its rotation stroke and rotation speed.

[0044] Furthermore, such as Figure 2 and Figures 9-12 As shown, to reduce the rotational friction between the rotating component 4 and the lifting component 3, a bearing 46 is installed in the upper accommodating cavity 442, and a bearing buckle 443 is installed on the connecting column 44 corresponding to the bearing. The bearing buckle connects the bearing to the lifting column, and the bearing connects the lifting column to the connecting column 44, which reduces the friction during rotation and avoids the noise generated by the plastic material when the traditional lifting column connecting column rotates. Since there is a round hole in the middle of the bearing, two sets of rotating bracket buckles 301 are also provided in the lifting column 30. The two sets of rotating buckles pass through the round hole and are placed below the bearing to engage with the lower end face of the bearing, thereby connecting the upper bracket and the lifting column and realizing the lifting of the rotating component with the lifting component. The clamping arm 43 of the lower rotating bracket 41 is provided with a socket 413, and the clamping arm of the upper rotating bracket 40 is provided with a corresponding plug 400. When connecting the upper rotating bracket and the lower rotating bracket, first align the clamping arms, insert the plug into the socket, and then tighten the screw.

[0045] Furthermore, such as Figure 11 and Figures 13-14As shown, the camera assembly 5 includes a camera housing 50, a camera mainboard 53 disposed within the camera housing, a first motor 55 connected to the camera mainboard, and a monitoring camera 51. The camera mainboard is electrically connected to a power board, and the camera housing has heat dissipation holes 54. A rotating column 52 is provided on one side of the camera housing, and the first motor shaft 56 passes through the other side of the camera housing. A through hole 411 is provided on the clamping arm 43 corresponding to the rotating column 52, and a first motor shaft hole 412 is provided corresponding to the first motor shaft, connecting the camera assembly to the clamping arm. The first motor shaft is non-circular. When the first motor operates and drives the first motor shaft to rotate, since the lower bracket cannot rotate in the vertical direction, the first motor will rotate vertically relative to the lower bracket, thereby driving the camera assembly 5 to rotate vertically within the clamping arm. A first stroke groove 57 is provided on the camera housing, and a first stroke block 410 is provided on the clamping arm corresponding to the first stroke groove. The first stroke block and the first stroke groove limit the rotational stroke of the camera assembly in the vertical direction.

[0046] In the manual lifting process of Embodiment 1, when the user needs to adjust the monitoring height, they can directly lift or press down the camera assembly 5 (or rotating assembly 4) vertically. The lifting column 30 of the lifting assembly 3 slides within the lamp plate fixing column 23, and the silicone ring 31 on it generates static friction with the inner wall of the lamp plate fixing column 23, providing lifting damping. When the desired height is reached, the camera assembly 5 is released, and the static friction overcomes the weight of the lifting assembly 3, rotating assembly 4, and camera assembly 5, stabilizing it at the new height position. The engagement of the lifting groove 230 and the abutment buckle 300 limits the maximum lifting stroke and prevents the assembly from completely disengaging. During the horizontal rotation process (first direction), when the monitoring direction needs to be adjusted horizontally, the second motor 45 is controlled to operate. The second motor 45 drives the first gear 47 on its shaft to rotate. Since the second gear 32 meshing with it is fixed through the lifting column 30, the rotational motion of the first gear 47 is converted into the revolution of the second motor 45 and the entire rotating assembly 4 around the axis of the lifting column 30, thereby driving the camera assembly 5 to achieve horizontal swaying rotation. After rotating to the target direction, the second motor 45 stops. During the pitch rotation process (second direction), when a vertical adjustment of the monitoring angle is required, the first motor 55 inside the camera assembly 5 is activated. The shaft of the first motor 55 drives the entire camera housing 50 to rotate relative to the clamping arm 43 of the rotating assembly 4, thereby achieving the pitch angle adjustment of the camera assembly 5. The cooperation between the first stroke slot 57 and the first stroke block 410 limits the maximum pitch angle.

[0047] The preferred embodiment of this application discloses a lifting and tilting video recorder, which differs from the first embodiment in that the lifting mechanism in the first embodiment is manually operated, with positioning achieved by the friction between the silicone ring 31 and the lamp plate fixing post 23. In the second embodiment, the lifting is driven by a motor. Figures 15-19 As shown, a motor bracket 35 is installed inside the lifting column 30, and a third motor 33 is connected to the motor bracket. A motor bracket buckle 301 is provided above the motor bracket, which connects the motor bracket 35 to the lifting column. Multiple sets of motor buckles 350 are provided below the motor bracket 35, and the third motor 33 is fixed to the motor bracket by the motor buckles. A threaded part 34 is connected to the shaft 340 of the third motor. A recessed cavity 351 is provided on the motor bracket corresponding to the threaded part. Since the third motor is an eccentric motor, the recessed cavity is located at a non-central position on the motor bracket. A side opening 352 is provided on the side of the motor bracket 35, which exposes part of the threaded part. At the same time, a window 302 is provided on the side of the lifting column corresponding to this part of the threaded part. Multiple sets of hook blocks 27 are provided on the inner wall of the lamp plate fixing column 23 corresponding to the threaded part. A gap 28 is left between every two sets of hook blocks. The outer surface of the threaded part 34 is threaded. When the third motor 33 drives the threaded part 34 to rotate, its outer thread interacts with the inclined side of the hook block 27. Since the hook block 27 is fixed to the inner wall of the lamp panel fixing post 23, the threaded part 34 will generate axial displacement along the inclined surface of the hook block 27 while rotating, thereby 'climbing' or 'descending' from one hook block position to an adjacent hook block position. This process is repeated, so that the lifting assembly 3 can be raised or lowered smoothly.

[0048] Furthermore, such as Figures 17-19 As shown, since the third motor 33 is an eccentric motor, the threaded component cannot be coaxially mounted with the lifting column. To ensure smoother lifting and lowering of the threaded column, the hook block 27 is tilted upwards, allowing it to provide a certain pulling force to the threaded component. This prevents the threaded component from shifting towards the recessed cavity 351 during rotation, resulting in smoother lifting and lowering of the threaded component. Consequently, it drives the lifting assembly 3 and the camera assembly 5 to rise and fall smoothly. The threaded component 34 can be shaped like an egg, smaller at the top and bottom and larger in the middle, allowing the threads to better engage with the hook block during rotation.

[0049] In Embodiment 2, the automatic lifting process is as follows: when the monitoring height needs to be adjusted, the third motor 33 is controlled to rotate forward or reverse. The third motor 33 drives the threaded component 34 to rotate. The threads on the outer wall of the threaded component 34 interact with the inclined hook block 27 fixed to the inner wall of the lamp plate fixing column 23, generating axial displacement, thereby driving the motor bracket 35, the lifting column 30, and the entire rotating assembly 4 and camera assembly 5 connected thereto to rise or fall smoothly. The inclined design of the hook block 27 generates radial tension on the threaded component 34, ensuring stable engagement and no shaking during the lifting process. After reaching the target height, the third motor 33 is stopped, and the threaded component 34 achieves self-locking and positioning at its current engagement position with the hook block 27, maintaining a stable height. Its horizontal rotation and pitch rotation processes are the same as in Embodiment 1, and will not be repeated here.
