Description

TECHNICAL FIELD

[0001] The application relates to the field of conference equipment technology, in particular to an adjusting and fixing base for a video conference display screen. BACKGROUND

[0002] The adjusting and fixing base for a video conference display screen is a device support structure specially designed for video conferences, which mainly functions to fix and adjust the position and angle of the video conference display screen to ensure optimal viewing effect and conference experience.

[0003] However, many existing base designs can only be fixed on the wall, providing limited adjustment flexibility, or can only be simply moved on the ground, but lack the ability to finely adjust the height and angle. For the base fixed on the wall, although it can provide stable support, once installed, its position and height are relatively fixed and difficult to adjust flexibly according to the layout changes of the conference room or the needs of the participants, which limits the applicability of the display screen in different scenarios, especially in situations where the position or height of the display screen needs to be frequently adjusted.

[0004] For the base that can only be moved on the ground, although it provides a certain flexibility, it often lacks precise adjustment functions for height and angle, which may result in the height and inclination angle of the display screen not fully meeting the viewing needs of the participants, affecting the conference efficiency and experience. In addition, the ground-moving base may also occupy the space of the conference room, affecting the overall layout and aesthetics. CONTENT OF THE INVENTION

[0040] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0041] This application discloses an adjustable fixing base for a video conferencing display screen.

[0042] Reference Figures 1-5 An adjustable fixing base for a video conferencing display screen includes a wall panel 100 and an outer protective plate 101 fixedly installed on one side of the wall panel 100 for aesthetic purposes. A U-shaped plate 103 is fixedly connected to the middle of the inner cavity of the outer protective plate 101. A movable shaft 105 is movably inserted through the middle of the bottom surface of the U-shaped plate 103. A cross groove 108 is opened on the upper part of the movable shaft 105, and it is inserted into a cross rod 107 fixed at the lower end of the lead screw 102. A cross rod 107 is also fixed on the side of the movable shaft 105 away from the lead screw 102, and it is inserted into a cross groove 108 opened at the output end of the servo motor 203. When the output end of the servo motor 203 rotates, it drives the movable shaft 105 to rotate, thereby driving the lead screw 102 to rotate. The lead screw 102 is threaded through a lifting push rod 311, so that when the lead screw 102 rotates, it can drive the lifting push rod 311 to move longitudinally back and forth.

[0043] Reference Figures 1-5On the inner wall of the opposite side of the U-shaped plate 103, several (at least two) T-shaped grooves 104 with the same structure are provided. At the four corners of the surface of the T-shaped groove 104 away from the wall panel 100, horizontal grooves 106 communicating with its inner cavity are provided. The four horizontal grooves 106 have the same structure and their height is greater than the height of the T-shaped slide rod 312, thus allowing the T-shaped slide rod 312 to be inserted into the horizontal grooves 106. The horizontal grooves 106 protrude from the surface of the U-shaped plate 103 away from the wall panel 100, thus allowing the T-shaped slide rod 312 to be inserted into the wall panel 100. After entering, it can provide stable support for the entire lifting and adjusting mechanism 300, thereby separating it from the movable adjusting mechanism 200. After separation, it pushes the entire lifting and adjusting mechanism 300 and then, through the cooperation of the T-shaped slide bar 312 and the horizontal slide groove 106, it can slide into the T-shaped slide groove 104. The horizontal slide groove 106 is higher than the bottom of the T-shaped slide bar 312, so that the entire lifting and adjusting mechanism 300 can slide into the U-shaped plate 103 and be offset from the opening of the horizontal slide groove 106, preventing the entire lifting and adjusting mechanism 300 from accidentally sliding out.

[0044] Since the cross bar 107 on the side of the movable shaft 105 away from the lead screw 102 is connected to the cross groove 108 at the output end of the servo motor 203, the rotation of the output end of the servo motor 203 drives the movable shaft 105 to rotate synchronously. Furthermore, since the cross groove 108 on the upper part of the movable shaft 105 is connected to the cross bar 107 at the lower end of the lead screw 102, the rotation of the movable shaft 105 further drives the lead screw 102 to rotate.

[0045] The lead screw 102 is threadedly connected to the lifting push rod 311. According to the principle of thread transmission, the rotation of the lead screw 102 is converted into the longitudinal movement of the lifting push rod 311. When the lead screw 102 rotates forward or backward, the lifting push rod 311 moves longitudinally up or down accordingly, thereby realizing the adjustment of the height of the video conferencing display screen installed on the lifting adjustment mechanism 300.

[0046] Using the T-shaped slide groove 104 and the horizontal slide groove 106 on the inner wall of the opposite side of the U-shaped plate 103, the lifting adjustment mechanism 300 and the movable adjustment mechanism 200 can be installed or disassembled. Since the horizontal slide groove 106 protrudes from the surface of the U-shaped plate 103 away from the wall panel 100 and its height is greater than the height of the T-shaped slide rod 312, the T-shaped slide rod 312 is first aligned and inserted into the horizontal slide groove 106. At this time, the T-shaped slide rod 312 can provide stable support for the entire lifting adjustment mechanism 300, allowing it to separate from the movable adjustment mechanism 200. Then, the entire lifting adjustment mechanism 300 is pushed, and the T-shaped slide rod 312 slides along the horizontal slide groove 106 and enters the interior of the T-shaped slide groove 104.

[0047] Because the horizontal slide groove 106 is positioned higher than the bottom of the T-shaped slide bar 312, when the entire lifting and adjusting mechanism 300 is fully slid into the U-shaped plate 103, the opening of the T-shaped slide bar 312 is offset from the opening of the horizontal slide groove 106, thereby preventing the entire lifting and adjusting mechanism 300 from accidentally sliding out and ensuring the stability and reliability of the display screen during use and adjustment.

[0048] Reference Figures 6-9 A lifting adjustment mechanism 300 is provided on one side of several T-shaped slide grooves 104. The lifting adjustment mechanism 300 includes a fixed plate 301 that is slidably disposed on one side of the T-shaped slide grooves 104. Several lifting plates 302, racks 303, and gears 304 are disposed inside the fixed plate 301. The lifting plates 302 are supported by the lifting plates 302. The gears 304 pass through the middle of the lifting plates 302 and the outer ring of the gears 304 protrudes from the side walls of the lifting plates 302. The racks 303 are fixedly disposed on one side surface of the lifting plates 302. Thus, the three components form a lifting device. Multiple lifting devices are arranged in an array in the cavity of the fixed plate 301. The racks 303 in two adjacent lifting devices are laterally staggered and the teeth of the two racks 303 are facing each other. The two adjacent gears 304 are also laterally staggered and can mesh with the two similarly staggered lifting plates 302 respectively.

[0049] Reference Figures 6-9 A rack 303 is fixedly installed on both side walls of the fixed plate 301, and the rack 303 can mesh with the gear 304 located in the middle of the lifting plate 302 at the edge. The lower end of the lifting plate 302 is fixedly connected to a T-shaped slide rod 312, and the middle part of the T-shaped slide rod 312 is threaded through the lead screw 102. When the lead screw 102 drives the T-shaped slide rod 312 to move, the T-shaped slide rod 312 can drive the lifting plate 302 to move, thereby causing the gear 304 at the middle to mesh with the gear fixed on the fixed plate 301. The rack 303 on the side wall drives the adjacent rack 303 fixed on the side of the lifting plate 302 to move in the same direction under the meshing principle, and then transmits in sequence, thereby driving the remaining lifting plate 302 to move, and thus driving the lifting plate 305 fixed to the rack 303 in the middle of the lifting device to move. It should be noted that the lifting devices will move in a stepped manner, that is, they will rise and fall like lifting rods. After rising, the lifting plate 305 is at the highest point and is higher than the other lifting plates 302.

[0050] Reference Figures 6-9During the movement of the lifting plate 305, the damping hinge 306 fixed on one side of it will move. The damping hinge 306 will then move the fixed back plate 310, which is fixedly supporting the display 109, synchronously on the side away from the lifting plate 305. Two identical connecting rods 307 are rotatably mounted at both ends of the damping hinge 306 via pivots. A connecting rod 309 with the same structure is rotatably mounted at the lower end of the connecting rod 307 on the side away from the damping hinge 306. Movable seats 308 are rotatably mounted on both sides of the lower end of the fixed back plate 310 at the junction of the connecting rod 309 and the connecting rod 307. Furthermore, a movable seat 308 is rotatably mounted on both sides of the lower end of the fixed back plate 310 at the junction of the connecting rod 309 and the connecting rod 307. One end of 10 is provided with a movable seat 308 with the same structure and is fixedly connected to the surface of the lifting plate 302 adjacent to the lifting plate 305. Since the lifting plate 302 and the lifting plate 305 do not move synchronously, when the lifting plate 305 moves, it will drive the damping hinge 306 and the connecting rod 307 to pull the movable seat 308 at the lower end of the fixed back plate 310. At the same time, the lifting plate 302, which is lower than the lifting plate 305, will apply a pulling force to the connecting rod 309 and transmit it to the movable seat 308 fixed on the fixed back plate 310. This will cause the fixed back plate 310 to rotate at a certain angle with the damping hinge 306 as the fulcrum. This angle is within the range of seventy degrees.

[0051] The T-shaped slide bar 312 is threaded through the lead screw 102 in the middle, and the lower end of the T-shaped slide bar 312 is fixedly connected to the lifting plate 302 at the edge. The rotation of the lead screw 102 drives the T-shaped slide bar 312 to move along the axial direction of the lead screw 102, thereby driving the lifting plate 302 connected to it to move.

[0052] Within the fixed plate 301, multiple lifting devices, consisting of a lifting plate 302, a rack 303, and a gear 304, are arranged in an array. The racks 303 of adjacent lifting devices are laterally offset with their teeth facing each other. The gears 304 are also laterally offset and can mesh with their corresponding lifting plates 302. The gears 304 at the center of the edge lifting plate 302 mesh with the racks 303 fixed on the side walls of the fixed plate 301. When the edge lifting plate 302 moves, its rotating gears 304 mesh with the racks on the side walls of the fixed plate 301. The rotation of 303 under meshing action causes the rack 303 on the side of the adjacent lifting plate 302 to move in the same direction. Then, through the meshing relationship between the gear 304 and the rack 303, the remaining lifting plates 302 move in succession. Since the lifting devices are arranged in a stepped manner, they rise and fall in sequence like lifting rods during the movement, eventually driving the lifting plate 305, which is fixed to the rack 303 in the middle of several lifting devices, to move. The lifted plate 305 after rising is at the highest point and is higher than the other lifting plates 302.

[0053] As the second lifting plate 305 moves, the damping hinge 306 fixed to it moves synchronously, thereby driving the fixed back plate 310 to move. Both ends of the damping hinge 306 are connected to the first connecting rod 307 via pivots. The lower end of the first connecting rod 307, along with the second connecting rod 309 and one of the movable seats 308, are simultaneously connected to the lower sides of the fixed back plate 310. The other end of the second connecting rod 309 is connected to the first lifting plate 302 adjacent to the second lifting plate 305 via the movable seat 308. However, because the movement of the first lifting plate 302 and the second lifting plate 305 is not synchronized, when… When the second lifting plate 305 moves, the damping hinge 306 and the first connecting rod 307 pull the movable seat 308 at the lower end of the fixed back plate 310. At the same time, the first lifting plate 302, which is lower than the second lifting plate 305, applies a pulling force to the second connecting rod 309 and transmits it to the movable seat 308 of the fixed back plate 310. Under the action of these forces, the fixed back plate 310 flips with the damping hinge 306 as the fulcrum. The flipping angle is within the range of seventy degrees up and down, thereby realizing flexible adjustment of the height and angle of the display 109 fixed on the fixed back plate 310.

[0054] Reference Figure 1 , Figure 2 , Figure 6 A movable adjustment mechanism 200 is provided on one side of the fixed plate 301. The movable adjustment mechanism 200 includes a U-shaped base plate 205 that is snapped onto the outside of the fixed plate 301. The inner diameter of the U-shaped base plate 205 differs from the outer diameter of the fixed plate 301 by two millimeters. Vertical slots 206 are provided in the middle of the side walls on both sides of the U-shaped base plate 205. The width of the vertical slots 206 is two millimeters greater than the width of the T-shaped slide rod 312 on the side of the fixed plate 301, so that the T-shaped slide rod 312 can be inserted into the vertical slots 206 and can slide and be limited. The insertion and limiting of the vertical slots 206 and the T-shaped slide rod 312 can make the entire lifting adjustment mechanism 300 and the U-shaped base plate 205 plugged and fixed, preventing the tipping phenomenon caused by the weight of the display 109 or accidental collision with the lifting adjustment mechanism 300.

[0055] Reference Figure 1 , Figure 2 , Figure 6 A fixed base plate 204 is bolted to the lower end of the U-shaped base plate 205. A recessed cavity is provided in the middle of the fixed base plate 204 to fix the servo motor 203. The output end of the servo motor 203 is provided with a cross groove 108. The inner cavity of the cross groove 108 can be inserted into the cross rod 107, so that the lead screw 102 with the cross rod 107 is fixed can be inserted into the output end of the servo motor 203 with the cross groove 108, so that the output end of the servo motor 203 can stably drive the lead screw 102 to rotate.

[0056] Reference Figure 1 , Figure 2 ,Figure 6 On the side of the fixed base plate 204 away from the U-shaped base plate 205, the telescopic ends of several servo push rods 202 with the same structure are fixedly connected by a connecting structure. The number of servo push rods 202 is set according to actual needs, and usually two servo push rods 202 are sufficient. A movable base 201 is fixedly set at the lower part of several servo push rods 202. The lower end of the movable base 201 is moved on the ground by self-locking casters. Thus, the monitor 109 and the lifting adjustment mechanism 300 can be hung on the wall panel 100 or moved to any position by the movable adjustment mechanism 200, increasing versatility while taking into account practicality.

[0057] The U-shaped base plate 205 is snapped onto the outside of the fixed plate 301. Its inner diameter differs from the outer diameter of the fixed plate 301 by two millimeters, allowing for a tight connection between the two. This enables the U-shaped base plate 205 to fix the entire lifting and adjusting mechanism 300. The vertical slots 206 on the middle of the side walls of the U-shaped base plate 205 are two millimeters wider than the width of the T-shaped slide rod 312 on one side of the fixed plate 301, allowing the T-shaped slide rod 312 to be smoothly inserted into the vertical slots 206. This allows the T-shaped slide rod 312 and the vertical slots 206 to slide and be limited, thus securing the entire lifting and adjusting mechanism 300 to the U-shaped base plate 205 and effectively preventing tipping caused by the weight of the display 109 or accidental contact with the lifting and adjusting mechanism 300 by staff.

[0058] At the lower end of the U-shaped base plate 205, a fixed base plate 204 is fixed by bolts. The recessed cavity in the middle of the fixed base plate 204 is used to fix the servo motor 203. The output end of the servo motor 203 is provided with a cross groove 108 and is connected to the cross rod 107 fixed at the lower end of the lead screw 102. When the servo motor 203 is started, its output end rotates and, with the help of the cross groove 108 and the cross rod 107, can stably drive the lead screw 102 to rotate synchronously, thereby providing power for the height adjustment mechanism 300.

[0059] The side surface of the fixed base plate 204 away from the U-shaped base plate 205 is fixedly connected to the telescopic ends of several servo push rods 202 through a connecting structure. The number of servo push rods 202 is usually set according to actual needs, and two are generally sufficient for common usage scenarios. The lower part of these servo push rods 202 is fixed on the movable base 201. The lower end of the movable base 201 is equipped with self-locking casters. When it is necessary to move the display 109 and the lifting adjustment mechanism 300, the overall height can be adjusted by controlling the extension and retraction of the servo push rods 202 to avoid obstacles or adapt to different ground conditions. It can also be adjusted to a comfortable viewing height for people in video conferences. By using the rolling of the casters, the entire device can be easily moved to the required position, and the device can be fixed by the self-locking function of the casters. Thus, the display 109 and the lifting adjustment mechanism 300 can be used by hanging on the wall panel 100, or can be flexibly moved to any position with the help of the movable adjustment mechanism 200, increasing the versatility and practicality of use.

[0060] It should be noted that the display 109, servo actuator 202, servo motor 203, and damping hinge 306 are all existing technologies, and their structural principles will not be elaborated here. The servo actuator 202 can be a folding base type servo actuator 202 from Wuxi Minyao, and the servo motor 203 can be a Mitsubishi AC servo motor HG-KN13J-S100 or HGKN13JS100. Both need to be connected to PLC or other controllers, but since they are existing technologies, they will not be described in detail here.

[0061] The implementation principle of the adjustable fixing base for a video conferencing display screen in this application embodiment is as follows: First, the servo motor 203 starts, and the cross groove 108 opened at its output end is inserted into the cross rod 107 fixed at the lower end of the lead screw 102. The lead screw 102 is rotated by rotation. The lead screw 102 and the lifting push rod 311 are threaded through each other. Therefore, the rotation of the lead screw 102 can be converted into the longitudinal reciprocating movement of the lifting push rod 311.

[0062] The movement of the lifting push rod 311 causes the lifting plate 302 located at the edge to move longitudinally. Through a number of lifting devices composed of gears 304, racks 303 and lifting plate 302, the lifting push rod 311 moves, causing the lifting plate 302 located at the edge to move. The gear 304 in the middle of the lifting plate 302 meshes with the rack 303 on the side wall of the fixed plate 301, so that the lifting plate 302 can rise through the meshing of the gear 304 and the rack 303, thereby causing the adjacent racks 303 and lifting plate 302 to move in the same direction. This transmission enables other lifting plate devices to lift in a stepped manner, thereby enabling several lifting plates 302 and lifting plates 305 to lift in a stepped manner.

[0063] The movement of the lifting plate 305 causes the damping hinge 306 and the fixed back plate 310 to move synchronously. At the same time, through the linkage of the connecting rod 307, the connecting rod 309 and the movable seat 308, the fixed back plate 310 can drive the display 109 to rotate up and down within a range of seventy degrees with the damping hinge 306 as the fulcrum, thereby realizing the height adjustment of the display screen and meeting the viewing needs of different angles.

[0064] Furthermore, the movable adjustment mechanism 200 allows the entire lifting and adjusting mechanism 300 to be inserted and fixed to the U-shaped base plate 205, thereby enabling the lifting and adjusting mechanism 300 to move stably along with the display 109. Simultaneously, through the cooperation of the servo push rod 202 and the movable base 201, and the insertion and fixing of the T-shaped slide rod 312 and the vertical slot 206, rapid separation between the lifting and adjusting mechanism 300 and the movable adjustment mechanism 200 is achieved. The servo push rod 202 and the movable base 201 also align the position of the T-shaped slide rod 312 with the horizontal slide groove 106. The movable lifting adjustment mechanism 300 and the movable adjustment mechanism 200 allow the T-shaped slide bar 312 to be inserted into the horizontal slide groove 106. Then, the height of the U-shaped base plate 205 is lowered by the servo push rod 202, thereby separating the U-shaped base plate 205 from the fixed plate 301 and the servo motor 203 from the lead screw 102. This allows the entire lifting adjustment mechanism 300 to move into the U-shaped plate 103 and be fixed by the U-shaped plate 103 and the T-shaped slide groove 104. At the same time, the cross bar 107 at the lower end of the lead screw 102 will also be inserted into the cross groove 108 on the movable shaft 105 at the lower middle part of the U-shaped plate 103.

[0065] Meanwhile, the U-shaped base plate 205 is separated from the fixed base plate 204. Then, the height of the fixed base plate 204 is adjusted by the servo push rod 202 so that it is not higher than the bottom of the U-shaped plate 103. The entire movable adjustment mechanism 200 is then pushed into the outer protective plate 101 and positioned at the lower end of the U-shaped plate 103. The height is then increased by the servo push rod 202, and the cross groove 108 at the output end of the servo motor 203 is connected to the cross rod 107 at the lower end of the movable shaft 105. This allows the output end of the servo motor 203 to rotate, thereby driving the lead screw 102 to rotate through the movable shaft 105. This enables the display 109 to achieve height and tilt angle adjustment through the lifting adjustment mechanism 300.

[0066] The above settings enable both mounting the monitor 109 on the wall panel 100 for display and allowing the monitor 109 to be moved.

[0067] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
