DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0029] A monitoring video recorder according to a preferred embodiment of the present invention; Figure 1-Figure 2 As shown, it includes a lamp head assembly 10, and a rotating assembly 20 arranged below the lamp head assembly and connected to the lamp head assembly. A camera assembly 30 is installed in the rotating assembly, and the camera assembly can be rotatably connected in the rotating assembly and can rotate relative to the lamp head assembly with the rotating assembly. A first motor 600 is arranged between the lamp head assembly and the rotating assembly, and a power board 50 connected to the first motor is arranged. The power board is connected to the mains power and the mains power is stepped down to supply power to the camera assembly so that the video recorder can perform monitoring and recording. At the same time, multiple groups of light board assemblies 40 are arranged around the lamp head assembly. The light board assemblies can provide lighting and provide a certain fill light effect for the work 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 realize monitoring in the left and right directions, and the camera assembly can rotate up and down in the rotating assembly to realize monitoring in the up and down directions, thereby realizing monitoring of the video recorder at any angle.

[0030] Specifically, Figure 2As shown, 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 board bracket 102 is connected to the lamp head. The power board is fixed by the power board bracket and installed in the lamp head. The threaded interface is connected to the mains power and transmitted to the power board and stepped down to 5V voltage under the action of the power board. Three groups of light board assemblies 40 are connected to the side of the lamp head assembly. The light board assembly is installed on the power 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 board 50. The camera assembly 30 is installed on the rotating bracket and realizes the rotation connection between the camera and the rotating bracket through the connection between the bracket housing and the rotating bracket. It should be noted that the threaded interface can also be replaced by other forms such as a socket to connect to the mains power, and the socket is connected to the power board to step down the mains power by the power board, or the power board is directly connected to the mains power and then stepped down to power the camera mainboard and the light board assembly to make them work.

[0031] Furthermore, if Figure 8-Figure 10 As shown, two groups of first card blocks 2000 are arranged opposite to each other on the side of the rotating bracket, an L-shaped card slot 2004 is formed above the first card block, and a second card block 2010 is arranged on the inner wall of the bracket shell corresponding to the L-shaped card slot. When the rotating bracket is connected to the bracket shell, the second card block is placed in the L-shaped card slot and rotated until the first card block is inserted into the L-shaped card slot. The rotating bracket is connected to the bracket shell, and at this time the first card block is placed above the second card block, so that the bracket shell and the rotating bracket can only be separated by rotating the rotating bracket.

[0032] Furthermore, if Figure 8-12 As shown, 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 shell 201 corresponding to the locking groove. When the first clamping block is rotated into the L-shaped clamping groove to clamp and fix the rotating bracket and the bracket shell, the locking rib just rotates into the locking groove, so that the locking structure is hidden between the rotating bracket and the bracket shell, and the assembled rotating component cannot be viewed from the outside to see the connection status, so that the rotating component can be prevented from being disassembled, and the setting of the locking structure does not affect the assembly of the rotating component. An opening portion 2012 is correspondingly provided on one side of the bracket shell, and the rotation stroke of the camera on the rotating component is adapted to the opening portion. Since the rotating component is made of plastic material, it has a certain deformation force. When the rotating component needs to be disassembled, it is necessary to slightly force the opening portion to cause a certain deformation. At this time, the locking rib is separated from the locking groove, and the rotating bracket can be rotated to separate the rotating bracket and the bracket shell.

[0033] Furthermore, it should be noted that if Fig.12As shown, 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 2013, the easier it is to unlock the locking structure due to the deformation force of the opening, that is, when the locking rib 2011 is located between the ab segments and closer to the position of point a, it is easier to unlock the locking structure, and the difficulty of unlocking becomes greater when it is close to point b; if the locking rib 2011 is placed between the bc segments, due to the limited deformation force of the bracket shell 201, it is basically impossible to separate the rotating bracket 200 and the bracket shell 201 in a normal way, and the locking structure can only be unlocked by violent means. When two sets of locking structures are provided, if there is a set of locking structures placed between the bc segments, it will also make it impossible to unlock the locking structure in a normal way; if both sets of locking structures are placed between the ab segments and on the same side of the opening, the locking structure can be unlocked only when it is close to point a, and if it is placed between the ab segments on both sides of the opening, it is still impossible to unlock the locking structure in a normal way. If the locking structure is set in an inclined state, it is difficult to unlock the locking structure due to the deformation force of the bracket shell, and it is also difficult to unlock the locking structure by normal means. Through the hidden setting of the above-mentioned locking structure, the loosening of the connection of the rotating assembly caused by the falling of the video recorder can be avoided, and the rotating assembly can also be avoided from being disassembled, and the assembly of the rotating assembly will not be affected, and the stability after assembly is higher. Therefore, through the connection of the hidden locking structure, the bracket shell can be disassembled only after deformation occurs. The deformation includes deformation within the range of slight deformation that the bracket shell material itself can withstand, and can be reset after deformation, as well as deformation caused by disassembly and destruction of the bracket shell and the rotating bracket by violent measures, and the deformation cannot be reset after occurrence.

[0034] Furthermore, if Figure 8-Figure 10 and Figure 13-14 As shown, the lower end of the rotating bracket 200 is provided with a left support ear 2006 and a right support ear 2005, and the two ends of the camera assembly 30 are respectively mounted on the left support ear and the right support ear. A receiving cavity is formed in the bracket housing 201, and an opening 2012 is formed on one side of the receiving cavity corresponding to the camera assembly. The camera assembly is placed in the receiving cavity. The camera assembly includes a camera housing 302, a camera mainboard 301 arranged in the camera housing, a camera 300 connected to the camera mainboard and mounted on the camera housing, and a second motor 601 connected to the camera housing. The camera is placed at the opening and rotates within the travel range of the opening under the action of the second motor. A rotating column 3020 is provided on one side of the camera housing, a connecting hole 20050 is provided on the right support ear 2005 corresponding to the rotating column, and a clamping groove 20060 is provided 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 achieve the connection between the camera assembly and the rotating bracket. A plurality of third clamping blocks 3021 are arranged in the camera housing 302, and the camera mainboard is clamped in the camera housing through the third clamping blocks.

[0035] Furthermore, if Figure 13-Figure 16 As shown, 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, two motor ears 6010 of the second motor 601, and a third rotating column 6013 driven by the motor, a second rotating column 6012 and a first rotating column 6011 are coaxially arranged and rotate synchronously with the third rotating column, and the second rotating column is placed between the first rotating column and the third rotating column, the first rotating column is arranged close to the second motor body, the first rotating column and the second rotating column are cylindrical, the third rotating column is non-cylindrical, and 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 arranged between the two groups of motor ear slots, a connecting plate slot 30222 is arranged on the second motor connecting plate, and a connecting plate through hole 30223 connected to the connecting plate slot is arranged 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 is not less than the radius of the first rotating column, and the width of the connecting plate slot is less than the radius of the first rotating column and is 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 sets 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 larger than the width of the connecting plate slot, it will abut against the second motor connecting plate and push the second motor connecting plate to produce a slight deformation. Continue to press the second motor down to the second motor fixing position until the second motor is installed in place. The first rotating column is placed at the through hole of the connecting plate, and the abutment force of the first rotating column on the second motor connecting plate disappears. The second motor connecting plate is reset under its own deformation reset force to clamp the first rotating column into the through hole of the connecting plate. Since the radius of the first rotating column is larger than the connecting plate slot, it cannot move upward, thereby realizing the connection between the second motor and the camera housing, and the second motor can be installed in the camera housing without using screws. The camera assembly connected to the second motor has its third rotating column installed in the clamping groove 20060 that matches 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 in the up and down direction 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 mainboard to the second motor, which does not belong to the protection scope of the present invention and will not be elaborated here. Figure 10-12 As shown, the bracket housing 201 is provided with heat dissipation holes 2013, which correspond to the camera mainboard to improve heat dissipation.

[0036] Furthermore, if Figure 4 and Figure 8-Figure 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.

[0037] Furthermore, if Figure 2-Figure 5 and Figure 7-Figure 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.

[0038] Furthermore, if Figure 1-Figure 3As shown, in order to improve the functionality of the video recorder, three groups of light board assemblies 40 are arranged around 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 be rotated relative to the lamp head assembly to open or retract the light board assembly. Three groups of light board connecting seats 1022 are arranged on the power board bracket. The light board connecting seats include two groups of light board fixing ears 10220 and a gap 10221 arranged between the two groups of light board fixing ears. The light board assembly 40 is placed in the gap and connected to the light board fixing ears, and can be rotated in the gap. An outer protrusion 10222 is arranged outside the gap, and a light board groove 1000 is arranged on the outer side of the lamp head corresponding to the outer protrusion. The light board assembly is placed in the light board groove and the power board bracket is pressed to install it in the lamp head assembly. The cooperation of the outer protrusion and the light 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 light board assembly. When the light board assembly is opened to the maximum angle, it contacts the outer protrusion.

[0039] Furthermore, if Figure 3-Figure 6 As shown, the light board assembly 40 includes an upper shell 400 and a light-transmitting lower shell 401 corresponding to the upper shell. A light-emitting light board 402 is arranged between the upper shell and the lower shell, and a light board heat dissipation hole 406 is arranged on the upper shell corresponding to the light board. One end of the light board assembly is connected to the lamp head assembly through a connecting end 403, and a rotating shaft 404 and a rotating block 405 are arranged on both sides of the connecting end. The rotating shaft and the rotating block are coaxially arranged and rotate synchronously. After placing the connecting end at the gap 10221, the lamp head 100 and the power board bracket 102 are tightened by screws to connect the light board assembly to 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 matched with the rotating shaft groove. The rotating block is placed in the rotating block groove and matched with the rotating block groove. The width of the rotating block groove is greater than the width of the rotating shaft groove. During installation, the connecting end can only enter the lamp board fixing ear from a vertical direction. A pressing block 1001 is provided in the lamp head corresponding to the rotating block. The pressing block presses the rotating block above the lamp board fixing ear so that the lamp board assembly can only rotate. 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 to a regular polygon. When the regular polygon rotates, the lamp board fixing column is slightly deformed and the deformation can be reset when it is rotated, so that it can be rotated to a specific side to achieve the current angle fixation, so as to achieve the fixation of the rotation angle of the lamp board assembly.
