[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.
[0025] Example 1: A multimedia video conferencing system device, such as Figure 1 - Figure 7 As shown, the multimedia display frame 1 includes a display screen 11 and a camera, and the multimedia display frame 1 is also provided with a fill light board 3 and an adjustment mechanism 4 for adjusting the angle of the fill light board 3; The adjustment mechanism 4 includes a carrying plate 41, which is installed on the multimedia display stand 1 at a certain angle. A telescopic cylinder 42 is installed on the carrying plate 41. The output end of the telescopic cylinder 42 is connected to a transmission plate 421. A tooth groove is formed on the transmission plate 421. Baffles 45 are extended on both sides of the carrying plate 41. An adjustment block 43 is rotatably installed between the left and right groups of baffles 45 through a movable shaft 44. The adjustment block 43 is correspondingly provided with convex teeth. The convex teeth of the adjustment block 43 are engaged with the tooth grooves of the transmission plate 421. An extended connecting block is provided on one end of the adjustment block 43, and the fill light board 3 is detachably installed on the extended connecting block at one end of the adjustment block 43.
[0026] Before starting a video conference, the angle of the fill light board 3 is adjusted according to the lighting conditions in the conference room and the positions of the participants. During adjustment, due to the overall tilt setting of the adjustment mechanism 4, the fill light board 3 is at the lowest angle. At this time, the telescopic cylinder 42 is started, and the output end of the telescopic cylinder 42 extends, pushing the transmission plate 421 connected thereto to move forward along the direction of the supporting plate 41. During the movement of the transmission plate 421, since the transmission plate 421 is formed with a tooth groove, and the protruding teeth of the adjustment block 43 engage with the tooth groove of the transmission plate 421, the movement of the transmission plate 421 drives the adjustment block 43 to rotate around the movable shaft 44. When the transmission plate 421 moves forward, the adjustment block 43 rotates clockwise around the movable shaft 44 according to the corresponding meshing relationship. Since a connecting block is extended at one end of the adjustment block 43, the fill light board 3 can be detachably mounted on the connecting block. Therefore, as the adjustment block 43 rotates, the fill light board 3 will also change its angle synchronously, thereby achieving fill light for participants in different positions.
[0027] like Figure 6 As shown, a limiting roller 46 is provided between the two sets of baffles 45 , and the transmission plate 421 can roll on the limiting roller 46 when it is extended or retracted, and the limiting roller 46 is made of a material with a smooth surface.
[0028] The smooth surface of the limiting roller 46 contacts the transmission plate 421. When the transmission plate 421 is extended or retracted, it rolls on the limiting roller 46, which greatly reduces the friction compared to moving on a rough surface, making the extension and retraction process of the transmission plate 421 smoother and reducing energy loss.
[0029] like Figure 1 - Figure 5 As shown, the light outlet of the fill light board 3 is provided with an inner cavity 31, and a soft light plastic plate 32 is embedded in the inner cavity 31. Since the light emitted by the fill light board 3 is usually more concentrated and strong, if it is directly irradiated on the participants, it may produce a glare effect, affecting the visual experience of the participants. The soft light plastic plate 32 can scatter and refract the light emitted by the fill light board 3, making the light softer and more uniform, thereby reducing the glare and uneven light and shadow phenomena, and making the facial lighting of the participants more natural and comfortable.
[0030] like Figure 1 、 Figure 4 、 Figure 5 As shown, the multimedia display stand 1 is further provided with a height adjustment plate 5. The two ends of the height adjustment plate 5 are slidably mounted in the vertical slide grooves 13 on both sides of the multimedia display stand 1. In addition, the height adjustment plate 5 can move up and down between the two sets of fixed plates 14 at the back end of the multimedia display stand 1 through screws 51. A vertical frame 52 is further provided at the upper end of the height adjustment plate 5, and the adjustment mechanism 4 is obliquely mounted on the vertical frame 52.
[0031] The height adjustment plate 5 is moved up and down in the vertical slide grooves 13 on both sides of the multimedia display stand 1 through the screw 51, which can flexibly change the height of the adjustment mechanism 4 and the fill light board 3. Since participants of different heights or different conference scene arrangements may have different requirements for the fill light height, this design allows the fill light board 3 to be adjusted to the optimal height according to actual conditions, ensuring that light can be irradiated on the participants at a suitable angle to achieve a better fill light effect.
[0032] Second embodiment: A multimedia video conferencing system device, such as Figure 1 - Figure 3 As shown, the multimedia display stand 1 is equipped with a support platform 2. A circular track groove 211 with a notch is opened on the surface of the support platform 2. The adjustment support plate 6 is placed inside the circular track groove 211 through a rotating shaft. A gear block 61 is set around the outer edge of the adjustment support plate 6. A transmission gear 62 is installed at the notch position of the circular track groove 211. The transmission gear 62 is engaged with the gear block 61 on the outer edge of the adjustment support plate 6. A rotating motor 63 is installed on one side of the support platform 2, and the transmission gear 62 is connected to the output end of the rotating motor 63.
[0033] The circular track groove 211 on the support platform 2 has a groove wall and a groove bottom designed to have a smooth surface structure. The smooth surface can significantly reduce the friction force encountered by the adjustment support plate 6 when it rotates in the circular track groove 211, making the rotation of the adjustment support plate 6 smoother and preventing jamming due to excessive friction, thereby ensuring the stability of its rotation and allowing it to be adjusted to the desired angular position more accurately.
[0034] During installation, the adjusting support plate 6 is installed inside the circular track groove 211 through the rotating shaft to ensure that it can move freely in the groove, and then the transmission gear 62 is installed in the notch position of the circular track groove 211 so that it is accurately meshed with the tooth block 61 on the outer edge of the adjusting support plate 6, and then the rotating motor 63 is installed on one side of the support platform 2, and ensure that the transmission gear 62 and the output end of the rotating motor 63 are correctly connected and firmly fixed. When the orientation needs to be adjusted according to the use requirements of the multimedia video conferencing system, the rotating motor 63 is started at this time, and the rotating motor 63 starts to run, and its output end drives the transmission gear 62 to rotate. Since the transmission gear 62 and the tooth block 61 on the outer edge of the adjusting support plate 6 are meshed with each other, the rotation of the transmission gear 62 will drive the adjusting support plate 6 to perform circular motion in the circular track groove 211. Since the groove wall and groove bottom of the circular track groove 211 are smooth, the friction when the adjusting support plate 6 moves can be minimized, so that it can rotate smoothly and smoothly.
[0035] Example 3: A multimedia video conferencing system device, such as Figure 1 - Figure 3As shown, the multimedia display stand 1 is further equipped with a support platform 2 , and the multimedia display stand 1 is mounted on a vertical adjustment base 21 of the support platform 2 in a height-adjustable manner via a connecting base 12 at the bottom.
[0036] The support platform 2 is also equipped with multiple sets of USB plugs 22 .
[0037] The support platform 2 is also integrated with a controller 23 , which can be electrically connected to the telescopic cylinder 42 through PLC programming technology.
[0038] When in use, the staff can push the support table 2 to a suitable meeting position. Since the support table 2 is easy to move, it can flexibly adapt to different meeting room layouts and space limitations. Then, the connecting card seat 12 at the bottom of the multimedia display rack 1 is connected to the vertical adjustment card seat 21 of the support table 2 for docking and installation. According to actual needs, the vertical adjustment card seat 21 can be adjusted to change the height of the multimedia display rack 1 to adapt to the best viewing angle in different scenes. Then, various electronic devices that need to be used in the meeting, such as laptops, tablets, microphones, projectors, etc., can be connected through the multiple sets of USB plugs 22 adapted on the support table 2. Before or during a meeting, if the angle of the fill light board 3 needs to be adjusted, the operator can quickly adjust the angle of the fill light board 3 through the controller 23 integrated on the support platform 2. The operator inputs the corresponding command through the controller 23. After receiving the command, the controller 23 sends an electrical signal to the telescopic cylinder 42 according to the PLC programming logic. The telescopic cylinder 42 starts working after receiving the electrical signal, thereby completing the rapid adjustment of the angle of the fill light board 3. It should be noted that the electrical connection method between the controller 23 and the telescopic cylinder 42 in this application is an existing mature technology and will not be introduced in detail here.
[0039] Working steps: Before use, the staff will push the support table 2 to a suitable meeting position, and then connect and install the connecting card seat 12 at the bottom of the multimedia display rack 1 with the vertical adjustment card seat 21 of the support table 2. The vertical adjustment card seat 21 can be adjusted according to actual needs to change the height of the multimedia display rack 1. After the height is adjusted, multiple sets of USB plugs 22 are provided on the support table 2 to provide a convenient access method for various electronic devices. Participants do not need to look for additional sockets or extension cords, and can directly connect laptops, tablets, microphones, projectors and other devices to the support table 2 through the USB plugs 22. This saves time and energy in connecting devices and improves the efficiency of meeting preparation. When adjusting the angle of the fill light panel 3, the telescopic cylinder 42 is activated. The output end of the telescopic cylinder 42 extends and pushes the transmission plate 421 to move along the direction of the carrier plate 41. Since the teeth on the transmission plate 421 engage with the convex teeth of the adjustment block 43, the movement of the transmission plate 421 drives the adjustment block 43 to rotate around the movable shaft 44. When the adjustment block 43 rotates, the angle of the fill light panel 3 connected to it is changed synchronously, thereby achieving fill light for participants in different positions. When adjusting the height of the fill light panel 3, the multimedia display stand 1 is provided with a height adjustment plate 5, the ends of which slide in the vertical slide grooves 13 on both sides of the multimedia display stand 1. By rotating the screw 51, the height adjustment plate 5 can be moved up and down between the two sets of fixed plates 14 at the back end of the multimedia display stand 1. Since the adjustment mechanism 4 is installed on the vertical frame 52 at the upper end of the height adjustment plate 5, the height of the adjustment mechanism 4 and the fill light panel 3 can be flexibly changed by raising and lowering the height adjustment plate 5, thereby meeting the fill light height requirements of participants of different heights or conference scenes. When the angle of the multimedia display stand 1 needs to be adjusted, the multimedia display stand 1 is equipped with a support platform 2. The surface of the support platform 2 has a circular track groove 211 with a notch. The adjustable support plate 6 is placed in the circular track groove 211 through a rotating shaft. The outer edge of the support plate 2 has a tooth block 61. A transmission gear 62 is installed at the notch of the circular track groove 211. The transmission gear 62 is engaged with the tooth block 61 of the adjustable support plate 6, and the transmission gear 62 is connected to the output end of the rotating motor 63 on one side of the support platform 2. The rotating motor 63 is started and the rotation of the rotating motor 63 drives the transmission gear 62 to rotate. Due to the gear meshing, the transmission gear 62 drives the adjustable support plate 6 to perform a circular motion in the circular track groove 211. At the same time, the smooth design of the groove wall and groove bottom of the circular track groove 211 reduces the friction when the adjustable support plate 6 moves, so that it can be rotated smoothly and smoothly to the required angle position to meet the requirements of the orientation of the multimedia display stand 1 in different conference scenarios.
