Description

Technical Field

[0001] The present invention relates to the field of video recorders, and more particularly to a surveillance video recorder. Background Art

[0002] A video recorder (camera), also known as a computer camera, computer eye, electronic eye, etc., is a video input device that is widely used in video conferencing, telemedicine, real-time monitoring, etc. Existing video recorders often require a large number of screws for fixation, with a cumbersome assembly process and low production efficiency. At the same time, the connection marks are obvious after the screws are tightened, making it easy to disassemble. Since the information recorded in devices such as video recorders is relatively sensitive, the information recorded in them may be lost after disassembly. Therefore, a surveillance video recorder that is convenient to assemble and not easy to disassemble is needed.

[0003] Chinese Patent Publication No. CN212960649U relates to the field of camera technology. It includes: a mounting bracket; an upper shell assembled to the lower side of the mounting bracket; a camera body provided on the lower side of the upper shell; a motor located inside the upper shell; a driving wheel connected to the output end of the motor inside the upper shell; and a driven wheel located inside the upper shell, meshing with the driving wheel and fixedly connected to the camera body. A connecting shaft fixedly connected to the inside of the driven wheel is provided on the upper side of the camera body. A plurality of limiting ports are provided at the upper end of the connecting shaft. A convex block corresponding to the limiting port is provided inside the driving wheel. The limiting port is clamped with the convex block, so that the connecting shaft is fixedly connected to the driven wheel. By adopting the above technical solution, it has the advantages of avoiding screw fixation when the driven wheel is fixed, reducing the damage rate of the driven wheel, and reducing the assembly process. This patent only avoids using screws at the gears, and a large number of screws are required for fixing the connection of the product shell, with a relatively complex assembly process and low production efficiency.

[0004] Chinese Patent Publication No. CN218772238U provides a camera device, which relates to the field of monitoring equipment, including a mounting component, a connecting component, and a camera. The mounting component includes a mounting base, and the mounting base is provided with a rotating ball groove. The connecting component includes a connecting piece, a pan-tilt sphere, and a fixed gear. The pan-tilt sphere and the fixed gear are respectively arranged at both ends of the connecting piece, and the pan-tilt sphere is rotatably arranged in the rotating ball groove. The camera includes a housing, a lens, a driving motor, and a driving gear provided on the housing. The housing is rotatably connected to the connecting piece. The driving gear is connected to the driving motor and meshes with the fixed gear. The driving motor can drive the driving gear to rotate, and through meshing cooperation, the housing and the lens can rotate relative to the connecting piece. In addition, the pan-tilt sphere can be rotated relative to the rotating ball groove to adjust the shooting angle of the camera lens in a large range. Through the comprehensive adjustment of the above two methods, the shooting area of the camera lens of the camera device is larger. This camera device is convenient to disassemble and is easily damaged after disassembly, resulting in information loss, and its use safety is insufficient. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that existing video recorders often require a large number of screws for fixation, the assembly process is relatively cumbersome, and the production efficiency is relatively low; at the same time, the connection marks are obvious when the screws are tightened, and it is easy to disassemble them. In view of the above defects of the prior art, a monitoring video recorder is provided.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

A power board and a first motor connected to the power board are arranged inside the lamp head assembly. A rotating assembly is connected below the lamp head assembly. A camera assembly that can rotate up and down is arranged inside the rotating assembly. The rotating assembly is driven by the first motor to rotate left and right and drives the camera assembly to rotate left and right. The rotating assembly includes a rotating bracket and a bracket housing connected to the rotating bracket. The rotating bracket and the bracket housing are rotationally connected through a clamping structure. A locking structure is also arranged between the rotating bracket and the bracket housing. When the rotating bracket and the bracket housing are not connected, the locking structure is not locked. When the clamping structure connects the rotating bracket and the bracket housing, the locking structure locks the rotating bracket and the bracket housing.

[0008] The monitoring video recorder with the above structure drives the rotating assembly to rotate left and right by the first motor to drive the camera assembly to rotate left and right, and the camera assembly can rotate up and down inside the rotating assembly, so as to realize the rotational monitoring of the camera in the up, down, left and right directions. Moreover, the rotating bracket and the bracket housing are rotationally connected through a clamping structure, and it is relatively easy to confirm the connection direction of the rotating bracket and the bracket housing during assembly. At the same time, it is locked with the cooperation of the locking structure. When the clamping structure rotates in place, the locking structure locks to connect and fix the rotating bracket and the bracket housing. The stability after connection is higher, and it does not require screws for fixation, saving costs and improving production efficiency.

[0009] In the above monitoring video recorder, preferably, a card slot is arranged inside the rotating bracket, and a second card block is arranged on the bracket housing corresponding to the card slot. The second card block is rotated into the card slot to connect the rotating bracket and the bracket housing. The locking structure is arranged on the contact surface between the rotating bracket and the bracket housing, and the rotating bracket and the bracket housing locked after the deformation of the rotating bracket or the bracket housing are unlocked.

[0010] The monitoring video recorder with the above structure uses a clamping structure connected by a card block and an L-shaped card slot, which is convenient to align the card block with the L-shaped card slot to realize the assembly of the rotating bracket and the bracket housing. At the same time, the locking structure is arranged on the contact surface to hide the locking structure. The locking structure can only be unlocked after the deformation of the rotating bracket or the bracket housing, ensuring the stability of the locking structure and preventing disassembly. And normal drops will not cause the separation of the rotating bracket and the bracket housing.

[0011] In the above-mentioned surveillance camera, preferably, the locking structure includes at least one set of locking ribs and locking grooves provided corresponding to the locking ribs. When the locking ribs rotate into the locking grooves, the locking structure is locked. The locking ribs are disposed on the inner wall of the bracket housing, and the locking grooves are disposed on the outer wall of the rotating bracket;

[0012] or the locking ribs are disposed on the outer wall of the rotating bracket, and the locking grooves are disposed on the inner wall of the bracket housing;

[0013] When the rotating bracket is connected to the bracket housing, the outer wall of the rotating bracket contacts the inner wall of the bracket housing.

[0014] The locking structure of the surveillance camera with the above structure adopts locking ribs and locking grooves, which are respectively arranged between the contact surfaces of the rotating bracket and the bracket housing, so as to facilitate hiding the locking structure and prevent the surveillance camera from being disassembled and damaged.

[0015] In the above-mentioned surveillance camera, preferably, the camera assembly includes a camera housing, a camera main board disposed in the camera housing, and a surveillance camera disposed on the camera housing. The surveillance camera is connected to the camera main board. An opening is provided on the bracket housing corresponding to the surveillance camera, and the surveillance camera moves up and down at the opening. A second motor fixing position is also provided on the camera housing, and a second motor is provided at the second motor fixing position. The second motor moves along a first direction to reach the second motor fixing position and is connected to the camera housing, and moves along a second direction to be locked to the camera housing at the second motor fixing position.

[0016] The second motor of the surveillance camera with the above structure reaches the second motor fixing position through the first direction and moves along the second direction at the second motor fixing position to realize the connection between the second motor and the camera housing, which is convenient for the installation and locking of the second motor. Moreover, the connection between the second motor and the camera housing can also drive the camera to rotate in the up and down directions.

[0017] In the above-mentioned surveillance camera, preferably, the second motor includes a first rotating column and a third rotating column that rotate coaxially and synchronously. Motor fixing ears are provided on both sides of the second motor. The second motor fixing position includes motor ear slots provided corresponding to the motor fixing ears, and a motor connecting plate disposed between the two groups of motor ear slots. A connecting plate through hole is provided in the middle of the motor connecting plate corresponding to the first rotating column. When the second motor moves along the motor ear slots, the third rotating column generates a pressing force on the motor connecting plate to deform the motor fixing ears or the motor connecting plate. When the motor fixing ears are inserted into the motor ear slots, the pressing force disappears, and the deformation of the motor fixing ears or the motor connecting plate is restored to push the third rotating column to move along a direction perpendicular to the motor ear slots into the connecting plate through hole.

[0018] At the second motor fixing position of the surveillance camera with the above structure, the third rotating column is used to make the motor fixing ear or the motor connecting plate deform by the abutting force between the third rotating column and the motor connecting plate. When the third rotating column reaches inside the through hole of the connecting plate, the abutting force between the third rotating column and the motor connecting plate disappears, and the deformation of the motor fixing ear or the motor connecting plate is restored, and the second motor is pushed along the movement to move the third rotating column into the through hole of the connecting plate, realizing the locking of the second motor and the camera housing without screws, saving costs, facilitating assembly, and being more stable after assembly.

[0019] In the above surveillance camera, preferably, a second rotating column is arranged between the first rotating column and the third rotating column. A connecting plate slot is arranged on the motor connecting plate. The connecting plate slot communicates with the through hole of the connecting plate, and the width of the connecting plate slot is smaller than the radius of the third rotating column and not less than the radius of the second rotating column. The radius of the through hole of the connecting plate is not less than the radius of the third rotating column. The first rotating column is non-cylindrical. The rotating bracket is provided with a left support ear and a right support ear corresponding to the camera. A clamping groove is arranged on the left support ear. The first rotating column is clamped into the clamping groove. A connecting hole is arranged on the right support ear. A rotating column is arranged on the camera housing corresponding to the connecting hole. The camera assembly is connected to the rotating bracket through the connection between the rotating column and the right support ear and the connection between the first rotating column and the left support ear.

[0020] Multiple groups of third clamping blocks are arranged inside the camera housing. The camera main board is connected to the camera housing through the third clamping blocks.

[0021] The surveillance camera with the above structure arranges a second rotating column between the first rotating column and the third rotating column, which is convenient for reducing the distance between the third rotating column and the motor fixing plate, enabling the motor fixing ear or the motor connecting plate to have better deformation force. At the same time, the movement of the second rotating column in the connecting plate slot can also prevent the second rotating column from shaking left and right, facilitating the movement of the third rotating column. At the same time, different radii or widths are set according to the abutting force to make the assembly better.

[0022] In the above surveillance camera, preferably, the lamp head assembly includes a lamp head and a power board bracket connected to the lamp head. A clamping sliding block is arranged at the lower end of the power board bracket. An outer flange is arranged on the upper end of the rotating bracket corresponding to the clamping sliding block. A sliding groove is formed below the outer flange. The clamping sliding block is clamped with the outer flange to connect the power board bracket and the rotating bracket, and the clamping sliding block can rotate left and right in the sliding groove. A power board support frame is arranged on the power board bracket. The power board is placed on the power board support frame. A motor rotating shaft through hole is arranged in the middle of the power board. The first motor rotating shaft is placed in the motor rotating shaft through hole.

[0023] The power supply board of the surveillance camera with the above structure is fixed through the power supply board bracket and the lamp holder, which facilitates the installation of the power supply board, makes the installation of the power supply board more convenient, and the installed power supply board has a certain position adjustment function, providing a position adjustment function when the power supply board bracket rotates relative to the rotating assembly, and the rotation is smoother. And the first motor is connected to the power supply board, and the power supply board bracket is rotatably connected to the rotating bracket to drive the rotating assembly to rotate when the first motor works.

[0024] In the above surveillance camera, preferably, a power supply board limit block is provided on the power supply board support frame, a limit groove is provided on the side of the power supply board corresponding to the power supply board limit block, at least one set of lamp board connection seats is provided on the side of the power supply board bracket, a lamp board assembly is connected at the lamp board connection seat, and a lamp board groove is provided on the lamp holder corresponding to the lamp board connection seat.

[0025] The power supply board of the surveillance camera with the above structure is installed on the power supply board bracket by connecting the limit block on the power supply board support frame with the limit groove of the power supply board, which is convenient for installation and cannot rotate on the power supply board bracket after installation. At the same time, a lamp board assembly is provided on the periphery of the lamp head assembly for lighting or monitoring fill light, improving the functionality of the video camera or making the monitoring clearer.

[0026] In the above surveillance camera, preferably, the lamp board assembly includes an upper shell and a light-transmitting lower shell connected to the upper shell. A light-emitting lamp board is provided between the upper shell and the lower shell. A connection end is provided on one side of the lamp board assembly, and rotating shafts are provided on both sides of the connection end. The lamp board connection seat includes two groups of lamp board fixing ears connected to the rotating shafts, and a gap is left between the two groups of lamp board fixing ears.

The radius of the rotating shaft groove is smaller than that of the rotating block groove. The rotating block is placed in the rotating block groove. The rotating block is a regular polygon so that the rotation angle of the lamp board assembly can be adjusted. An outward convex block is also provided in the gap to limit the opening of the lamp board assembly.

At the same time, an outward convex block is provided to limit the opening of the lamp board assembly, and the outward convex block also facilitates the connection between the lamp holder and the power supply board bracket, facilitating assembly.

[0030] The beneficial effects of the present invention are as follows: The rotating bracket is connected to the bracket housing through a hidden locking structure.

[0048] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0049] A monitoring video recorder according to a preferred embodiment of the present invention; as Figures 1 - 2As shown in the figure, it includes a lamp head assembly 10, and a rotating assembly 20 arranged below and connected to the lamp head assembly. A camera assembly 30 is installed inside the rotating assembly, and the camera assembly is rotatably connected inside the rotating assembly and can rotate relative to the lamp head assembly along with the rotating assembly. A first motor 600 is arranged between the lamp head assembly and the rotating assembly, and a power supply board 50 is connected to the first motor. The mains power is accessed through the power supply board and stepped down by the power supply board to supply power to the camera assembly so that the video recorder can perform monitoring and recording work. At the same time, multiple groups of lamp board assemblies 40 are arranged on the periphery of the lamp head assembly. The lamp board assemblies can not only provide illumination but also provide a certain supplementary lighting effect for the operation of the video recorder. Since the rotating assembly can rotate left and right relative to the lamp head assembly, it can drive the camera assembly to rotate left and right to achieve monitoring in the left and right directions, and the camera assembly can rotate up and down inside the rotating assembly to achieve monitoring in the up and down directions, thereby realizing the monitoring of the video recorder at any angle.

[0050] Specifically, as Figure 2 shown in the figure, the lamp head assembly 10 includes a conical lamp head 100 and a threaded interface 101 arranged at the upper end of the lamp head. A power supply board bracket 102 is connected inside the lamp head. After the power supply board is fixed by the power supply board bracket, it is installed inside the lamp head. After the threaded interface accesses the mains power, it is transmitted to the power supply board and stepped down to 5V voltage under the action of the power supply board. Three groups of lamp board assemblies 40 are connected to the side of the lamp head assembly. The lamp board assemblies are installed on the power supply board bracket and fixed by the lamp head. The rotating assembly 20 includes a rotating bracket 200 and a bracket housing 201 connected to the rotating bracket. The first motor 600 is installed on the rotating bracket and connected to the power supply board 50. The camera assembly 30 is installed on the rotating bracket, and the rotation connection between the camera and the rotating bracket is realized through the connection between the bracket housing and the rotating bracket. It should be noted that the threaded interface can also be replaced with other forms such as a socket to access the mains power, and the socket is connected to the power supply board. The power supply board steps down the mains power, or the power supply board is directly connected to the mains power and stepped down to supply power to the camera main board and the lamp board assemblies to make them work.

[0051] Furthermore, as Figures 8 - 10 shown in the figure, two groups of first clamping blocks 2000 are arranged opposite to each other on the side of the rotating bracket. An L-shaped clamping groove 2004 is formed above the first clamping blocks. Second clamping blocks 2010 are arranged on the inner wall of the bracket housing corresponding to the L-shaped clamping groove. When the rotating bracket is connected to the bracket housing, place the second clamping block at the L-shaped clamping groove and rotate until the first clamping block is clamped into the L-shaped clamping groove. At this time, the rotating bracket is connected to the bracket housing, and the first clamping block is placed above the second clamping block, so that the bracket housing and the rotating bracket can be separated only by rotating the rotating bracket.

[0052] Furthermore, as Figures 8 - 12As shown in the figure, a locking groove 2008 is provided on the outer side of the rotating bracket 200, and a locking rib 2011 is provided on the inner wall of the bracket housing 201 corresponding to the locking groove. When the first clamping block rotates to be engaged with the L-shaped clamping groove to fix the rotating bracket and the bracket housing, the locking rib just rotates into the locking groove, realizing the hiding of the locking structure between the rotating bracket and the bracket housing. Moreover, the assembled rotating assembly cannot be seen from the outside to check its connection situation, which can avoid the disassembly of the rotating assembly, and the setting of the locking structure does not affect the assembly of the rotating assembly. An opening part 2012 is correspondingly provided on one side of the bracket housing, and the rotation stroke of the camera on the rotating assembly is adapted to the opening part. Since the rotating assembly is made of plastic material and has a certain deformation force, when it is necessary to disassemble the rotating assembly, a little force needs to be applied to the opening part to make it deform to a certain extent. At this time, the locking rib disengages from the locking groove, and then the rotating bracket can be rotated to separate the rotating bracket and the bracket housing.

[0053] Furthermore, it should be noted that, as Figure 12 shown in the figure, if the locking structure is in a vertical state, when only one set of locking structures is provided, the closer the locking structure is to the opening part 2013, the easier it is to unlock the locking structure by the deformation force of the opening part. That is, when the locking rib 2011 is between the ab section and closer to the a point, it is easier to unlock the locking structure, while the difficulty of unlocking gradually increases when approaching the b point; if the locking rib 2011 is placed between the bc section, due to the limited deformation force of the bracket housing 201, it is basically impossible to separate the rotating bracket 200 and the bracket housing 201 through normal means, and only by violent means can the locking structure be unlocked. When two sets of locking structures are provided, if a certain set of locking structures is placed between the bc section, it will also make it impossible to unlock the locking structure through normal means; if both sets of locking structures are placed between the ab section and on the same side of the opening part, the locking structure can only be unlocked when approaching the a point, while if they are placed between the ab sections on both sides of the opening part, it is still impossible to unlock the locking structure through normal means. If the locking structure is set in an inclined state, it is also difficult to unlock the locking structure by the deformation force of the bracket housing, and it is also difficult to unlock the locking structure through normal means. Through the hidden setting of the above-mentioned locking structure, it is possible to avoid the loosening of the connection of the rotating assembly caused by the dropping of the video recorder, and at the same time, it is possible to avoid the disassembly of the rotating assembly, and it does not affect the assembly of the rotating assembly, and the stability after assembly is higher. Therefore, through the connection of the hidden locking structure, the bracket housing can be disassembled only after deformation. The deformation includes the deformation within the subtle deformation range that the bracket housing material itself can withstand and can be reset after deformation, as well as the deformation caused by violent measures to disassemble and damage the bracket housing and the rotating bracket, and the deformation cannot be reset after it occurs.

[0054] Furthermore, as Figures 8 - 10 and Figures 13 - 14As shown in the figure, the lower end of the rotating bracket 200 is provided with a left support ear 2006 and a right support ear 2005, and both ends of the camera assembly 30 are respectively installed on the left support ear and the right support ear. An accommodation cavity is formed inside the bracket housing 201, and an opening 2012 is formed on one side of the accommodation cavity corresponding to the camera assembly. The camera assembly is placed inside the accommodation cavity. The camera assembly includes a camera housing 302, and a camera main board 301 arranged inside the camera housing. A camera 300 is connected to the camera main board and installed on the camera housing. A second motor 601 is connected to the camera housing. The camera is placed at the opening and rotates within the stroke range at the opening under the action of the second motor. A rotating column 3020 is arranged on one side of the camera housing. A connecting hole 20050 is arranged on the right support ear 2005 corresponding to the rotating column. A clamping groove 20060 is arranged on the left support ear 2006. The rotating shaft of the second motor is connected to the camera housing and clamped into the clamping groove to realize the connection between the camera assembly and the rotating bracket. Multiple groups of third clamping blocks 3021 are arranged inside the camera housing 302, and the camera main board is clamped inside the camera housing through the third clamping blocks.

[0055] Further, as Figures 13 - 16As shown in the figure, in order to facilitate the connection between the second motor and the camera housing, a second motor fixing position 3022 is provided on one side of the camera housing corresponding to the second motor. The second motor 601 has two motor ears 6010 on both sides, and a third rotating column 6013 driven by the motor. A second rotating column 6012 and a first rotating column 6011 are coaxially arranged with the third rotating column and rotate synchronously. The second rotating column is disposed between the first rotating column and the third rotating column. The first rotating column is disposed close to the second motor body. The first rotating column and the second rotating column are cylindrical, and the third rotating column is non-cylindrical. At the same time, the radius of the first rotating column is greater than the radius of the second rotating column. The second motor fixing position 3022 includes two groups of motor ear slots 30220 corresponding to the motor ears, and a second motor connecting plate 30221 disposed between the two groups of motor ear slots. A connecting plate slot 30222 is provided on the second motor connecting plate. A connecting plate through hole 30223 communicating with the connecting plate slot is provided in the middle of the second motor connecting plate. The radius of the connecting plate through hole is greater than the width of the connecting plate slot and not less than the radius of the first rotating column. The width of the connecting plate slot is less than the radius of the first rotating column and not less than the radius of the second rotating column. When the second motor 601 is installed in the second motor fixing position 3022, the two groups of motor ears 6010 are inserted into the motor ear slots 30220. At this time, the second rotating column 6012 can be inserted into the connecting plate slot. Since the radius of the first rotating column is greater than the width of the connecting plate slot, it will abut against the second motor connecting plate and cause a slight deformation of the second motor connecting plate. Continue to press down the second motor to the second motor fixing position until the second motor is installed in place. At this time, the first rotating column is disposed at the connecting plate through hole, and the abutting force of the first rotating column on the second motor connecting plate disappears. The second motor connecting plate is reset under its own deformation restoring force and clamps the first rotating column into the connecting plate through hole. And because the radius of the first rotating column is greater than the connecting plate slot, it cannot move upward, so the connection between the second motor and the camera housing can be realized, and the second motor can be installed in the camera housing without using screws. The camera assembly connected with the second motor installs its third rotating column into the clamping groove 20060 adapted to the third rotating column. When the second motor 601 works to drive the third rotating column to rotate, since the third rotating column cannot rotate in the clamping groove, the second motor body rotates up and down relative to the third rotating column, and then drives the camera assembly to rotate up and down in the rotating assembly. The rotation angle can be controlled by the camera main board for the second motor, which does not belong to the protection scope of the present invention and will not be specifically described here. As Figures 10 - 12 As shown in the figure, heat dissipation holes 2013 are provided on the bracket housing 201. The heat dissipation holes correspond to the camera main board to improve heat dissipation performance.

[0056] Furthermore, as Figure 4 and Figures 8 - 9As shown, a motor fixing column 2003 is provided at the upper end of the rotating bracket 200, and the first motor is connected to the rotating bracket through the motor fixing column. An outer flange 2001 is provided on the peripheral side of the rotating bracket, and a sliding groove 2002 is formed below the outer flange. A plurality of sets of clamping sliding blocks 1025 are provided on the inner wall of the power board bracket 102 corresponding to the sliding groove. When installing, the power board bracket is placed on the rotating bracket, and pressed to make the power board bracket slightly deformed until the clamping sliding block passes over the outer flange and is clamped into the sliding groove 2002, so that the rotating assembly and the lamp head assembly can be connected, and the connected rotating assembly can rotate in the left and right directions relative to the lamp head assembly. A stop block 1026 is provided on the inner wall of the power board bracket, and a stop plate 2007 is provided on the rotating bracket corresponding to the stop block. When the rotating assembly rotates relative to the lamp head assembly until the stop plate contacts the stop block, it will not be able to continue to rotate and can only rotate in the opposite direction.

[0057] Furthermore, if Figures 2 - 5 and Figures 7 - 9 As shown, two groups of power board support frames 1020 are arranged on the power board support frame 102, the power board is installed on the power board support frame, and two groups of power board limit blocks 1023 are arranged on the power board support frame, and a limit groove 500 is arranged on the power board corresponding to the power board limit block, and the power board is connected to the power board support frame by connecting the limit groove and the power board limit block, and a through hole 1024 is arranged on the power board support corresponding to the first motor, the first motor is installed on the rotating bracket and passes through the first motor shaft to connect the power board and then lock it by screws, and a motor shaft hole 501 is arranged in the middle of the power board corresponding to the first motor shaft, the first motor shaft is non-cylindrical, and the motor shaft hole is adapted to the shape of the first motor shaft, so that when the first motor drives the first motor shaft to rotate, the first motor body rotates relative to the first motor shaft, and then drives the rotating bracket to rotate in the left and right directions, and drives the camera assembly to rotate in the left and right directions, so as to realize the rotation monitoring of the camera in the left and right directions. At the same time, since the two sides of the power board are limited only by the limit blocks, when the rotating assembly and the power board bracket are not rotated in parallel, the power board will produce a slight shake to enable it to have a certain position correction function, making the rotation smoother. It should be noted that the first motor is also electrically connected to the camera control board, and the rotation signal can be provided by the camera control board, which does not belong to the protection scope of the present invention and will not be elaborated here.

[0058] Furthermore, if Figures 1 - 3As shown in the figure, in order to improve the functionality of the video recorder, three groups of lamp board assemblies 40 are arranged on the periphery of the lamp head assembly 10. The illumination module is clamped and fixed by the power board bracket 102 and the lamp head 100 and can rotate relative to the lamp head assembly to open or retract the lamp board assembly. Three groups of lamp board connection seats 1022 are arranged on the power board bracket. The lamp board connection seat includes two groups of lamp board fixing ears 10220 and a gap 10221 arranged between the two groups of lamp board fixing ears. The lamp board assembly 40 is placed in the gap and connected to the lamp board fixing ears, and can rotate in the gap. An outer convex block 10222 is arranged outside the gap, and a lamp board groove 1000 is arranged on the outside of the lamp head corresponding to the outer convex block. The lamp board assembly is placed in the lamp board groove and is pressed by the power board bracket to be installed in the lamp head assembly. The cooperation of the outer convex block and the lamp board groove can facilitate the installation of the power board bracket and the lamp head, and also provide a limit for the opening of the lamp board assembly. When the lamp board assembly is opened to the maximum angle, it contacts the outer convex block.

[0059] Further, as Figures 3 - 6 shown, the lamp board assembly 40 includes an upper shell 400 and a light-transmitting lower shell 401 corresponding to the upper shell. A light-emitting lamp board 402 is arranged between the upper shell and the lower shell. Lamp board heat dissipation holes 406 are arranged on the upper shell corresponding to the lamp board. One end of the lamp board assembly is connected to the lamp head assembly through a connection end 403. Rotating shafts 404 and rotating blocks 405 are arranged on both sides of the connection end. The rotating shafts and the rotating blocks are coaxially arranged and rotate synchronously. After placing the connection end at the gap 10221, the lamp head 100 and the power board bracket 102 are locked by screws to connect the lamp board assembly and the lamp head assembly. The lamp board fixing ear 10220 includes a rotating block groove 10223 and a rotating shaft groove 10224. The rotating shaft 404 is placed in the rotating shaft groove and is adapted to the rotating shaft groove. The rotating block is placed in the rotating block groove and is adapted to the rotating block groove. The width of the rotating block groove is greater than the width of the rotating shaft groove. During installation, the connection end can only enter the lamp board fixing ear from the vertical direction. A pressing block 1001 is arranged in the lamp head corresponding to the rotating block. The rotating block is pressed above the lamp board fixing ear by the pressing block so that the lamp board assembly can only rotate, and the width of the rotating shaft groove is less than the width of the rotating block so that the lamp board assembly cannot move left and right. At the same time, the rotating block 405 is set as a regular polygon. When the regular polygon rotates, it slightly deforms the lamp board fixing column and can be deformed and reset when rotating to a certain position, so that it can be fixed at a specific side after rotating to a certain angle to fix the rotation angle of the lamp board assembly.
