Description

Technical Field

[0001] This application relates to the field of electronic nameplate technology, and more particularly to an e-ink screen conference room nameplate. Background Technology

[0002] Conference room nameplates are an indispensable identification tool in modern meetings. Unlike fixed paper nameplates, a key advantage of electronic nameplates is their adjustable display content and viewing angle, adapting to different attendees' eye levels and enhancing the meeting experience. However, in current technology, electronic nameplates often suffer from poorly designed adjustable screen angles. When the user rotates the screen, the shift in the center of gravity can cause the entire nameplate to lose balance and tip over. This not only affects the user experience but may also damage the equipment.

[0003] Therefore, there is a need to provide an anti-tipping e-ink conference room nameplate. Utility Model Content

[0004] In view of this, it is necessary to provide an anti-tipping e-ink conference room nameplate to solve the above problems.

[0005] An embodiment of this application provides an e-ink conference room nameplate, which stands on a support surface. The e-ink conference room nameplate includes: The display screen is set vertically. The base includes a first support portion and a second support portion extending in a horizontal direction. The first support portion and the second support portion are symmetrically arranged from the side of the display screen, and the first support portion and the second support portion enclose a support area located on the bearing surface in the vertical direction. A support shaft is provided, one end of which is rotatably mounted on the base, and the other end is connected to the display screen, and is centrally located along the width direction between the first support part and the second support part; When the display screen rotates relative to the base around the support axis, the vertical projection of the display screen is located within the support area.

[0006] In at least one embodiment of this application, the display screen has a first side and a second side facing away from each other, and both the first side and the second side are provided with an electronic ink screen.

[0007] In at least one embodiment of this application, the aspect ratio of the display screen is 16:9 or 21:9.

[0008] In at least one embodiment of this application, the base further includes: a limiting rotation part, which is disposed on the outer periphery of the supporting rotating shaft and is fixedly connected to the first supporting part and the second supporting part; The inner wall of the limiting rotation part has a limiting surface, and the end of the display screen near the supporting rotating shaft abuts against the limiting surface to limit the maximum rotation angle of the display screen.

[0009] In at least one embodiment of this application, the base includes an arc-shaped connecting portion that connects the first support portion and the second support portion. When viewed in the vertical direction, the arc-shaped connecting portion is recessed from the bearing surface along the side facing the display screen.

[0010] In at least one embodiment of this application, the base further includes two counterweight areas. When viewed vertically, the two counterweight areas are respectively disposed on the first support portion and the second support portion with the central axis of the support shaft as the axis of symmetry, and are located at both ends of the arc-shaped connecting portion.

[0011] In at least one embodiment of this application, the base further includes a drive plate, which is disposed between the two counterweight areas and on the arc-shaped connecting portion; The e-ink conference room nameplate also includes a power interface, which is located on the side of the base and is electrically connected to the driver board.

[0012] In at least one embodiment of this application, the supporting shaft is a hollow structure, and a wiring channel for passing through a flexible ribbon cable is provided inside the supporting shaft to electrically connect the display screen and the driving board.

[0013] In at least one embodiment of this application, the base further includes: a first bottom surface and a second bottom surface, one end of the arc-shaped connecting portion is connected to the first bottom surface and the other end is connected to the second bottom surface, and the first bottom surface and the second bottom surface are respectively in contact with the bearing surface.

[0014] In at least one embodiment of this application, the base further includes an anti-slip pad, which is disposed on the first bottom surface and the second bottom surface respectively.

[0015] The aforementioned e-ink conference room nameplate utilizes a base with symmetrically extending first and second support sections to form a stable support area. Combined with a centrally located support pivot, this ensures that the screen's vertical projection always falls within the support area when rotated at any angle. This limits the screen's center of gravity to within the base's support area, thus avoiding the risk of tipping over due to rotational shifts in the center of gravity. Attached Figure Description

[0020] An embodiment of this application provides an e-ink conference room nameplate, which stands on a support surface. The e-ink conference room nameplate includes: The display screen is set vertically. The base includes a first support portion and a second support portion extending in a horizontal direction. The first support portion and the second support portion are symmetrically arranged from the side of the display screen, and the first support portion and the second support portion enclose a support area located on the bearing surface in the vertical direction. A support shaft is provided, one end of which is rotatably mounted on the base, and the other end is connected to the display screen, and is centrally located along the width direction between the first support part and the second support part; When the display screen rotates relative to the base around the support axis, the vertical projection of the display screen is located within the support area.

[0021] The aforementioned e-ink conference room nameplate utilizes a base with symmetrically extending first and second support sections to form a stable support area. Combined with a centrally located support pivot, this ensures that the screen's vertical projection always falls within the support area when rotated at any angle. This limits the screen's center of gravity to within the base's support area, thus avoiding the risk of tipping over due to rotational shifts in the center of gravity.

[0022] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0023] according to Figures 1-4 This application provides an e-ink conference room nameplate 100, which stands on a support surface. The e-ink conference room nameplate includes: a display screen 10, a base 20 and a supporting pivot 30.

[0024] The display screen 10 is positioned vertically along direction F1. The base 20 includes a first support portion 21 and a second support portion 22 extending horizontally. The first support portion 21 and the second support portion 22 are symmetrically arranged from the side of the display screen 10, and they enclose a support area 20a on the bearing surface in the vertical direction F1. A support shaft 30 is rotatably mounted on the base 20 at one end and connected to the display screen 10 at the other end, and is centrally located along the width direction between the first support portion 21 and the second support portion 22.

[0025] When the display screen 10 rotates relative to the base 20 around the support pivot 30, the vertical projection of the display screen 10 is located within the support area 20a.

[0026] Specifically, the display screen 10 has a plate-like structure and is basically vertical when not adjusted, so as to display the names, titles, or seating information of the participants from the front. The supporting surface can be a horizontal tabletop, table surface, etc., for placing the e-ink conference room nameplate.

[0027] Furthermore, a first support portion 21 and a second support portion 22 extend along the vertical direction F1 towards both sides of the thickness direction of the display screen 10. These two portions are located on the lower sides of the display screen 10, respectively, and are symmetrically arranged with respect to the central axis of the display screen 10 when viewed from the vertical direction F1. The lower surfaces of the first support portion 21 and the second support portion 22 are in contact with the bearing surface. The first support portion 21 and the second support portion 22 form a support area 20a extending from the thickness direction of the base 20 on the bearing surface, thereby supporting the conference room nameplate on the bearing surface.

[0028] This symmetrically unfolded structure increases the horizontal support span of the base 20 and creates a clear and stable support range for the support area 20a below the display screen 10, providing a foundation for subsequent anti-tipping effects.

[0029] Furthermore, the support shaft 30 is centrally located along the width direction between the first support portion 21 and the second support portion 22, that is, the support shaft 30 is approximately located at the center line of the support area 20a in the lateral direction. Figure 3 and Figure 4 As can be seen from the side view shown, the axis of the support pivot 30 is perpendicular to the vertical direction F1, thereby allowing the display screen 10 to rotate around the support pivot 30 in the forward and backward directions in the vertical direction F1.

[0030] In the operation of this embodiment, the base 20 is first placed on a supporting surface such as a conference table, so that the first support 21 and the second support 22 are fully in contact with the supporting surface, forming a stable support boundary. Then, the user holds the upper edge of the display screen 10 according to their own sitting posture, height, or conference room layout, causing the display screen 10 to rotate forward or backward around the support pivot 30. When the display screen 10 rotates, the overall weight of the display screen 10 acts along the vertical direction F1, and its projection position in the vertical direction F1 will change. However, since the support pivot 30 is centrally located and the support area 20a provided by the base 20 is wide enough, the vertical projection of the display screen 10 always falls within the support area 20a throughout the entire adjustable angle range.

[0031] In one specific embodiment, the display screen 10 has a first side 11 and a second side 12 facing away from each other, and both the first side 11 and the second side 12 are provided with an electronic ink screen.

[0032] Specifically, the display screen 10 has a plate-like structure. Its first side 11 faces the side of the attendees, while its second side 12 faces the attendees on the other side. The first side 11 and the second side 12 are parallel to each other in space and share the same supporting substrate. Thus, when the display screen 10 rotates around the supporting pivot 30, the two sides can tilt synchronously with the display screen 10 as a whole.

[0033] Furthermore, an electronic ink screen is installed on the first side 11 and the second side 12 respectively. The two electronic ink screens are connected to the driving module through internal electrical connections and can refresh the display content independently or synchronously according to control commands.

[0034] In one specific embodiment, the aspect ratio of the display screen 10 to its width satisfies 16:9 or 21:9.

[0035] Specifically, the display screen 10 has a rectangular shape, with the vertical side F1 serving as the width of the display screen 10 and the horizontal side serving as the length of the display screen 10. The length-to-width ratio of the display screen 10 is designed to be 16:9 or 21:9.

[0036] Furthermore, by limiting the aspect ratio of the display screen 10 to 16:9 or 21:9, on the one hand, the larger aspect ratio allows the display screen 10 to have sufficient display height in the vertical direction F1, enabling the display of multiple lines of content such as names, titles, company names, and meeting information on the same screen without appearing crowded; on the other hand, the relatively moderate horizontal width makes the projection width of the display screen 10 significantly smaller than the width of the support area 20a of the base 20. When the display screen 10 tilts forward or backward around the support pivot 30, its vertical projection is still easily controlled within the support area 20a, which is beneficial for cooperating with the anti-tipping structure of the base 20 and further improving the overall placement stability.

[0037] In one specific embodiment, the base 20 further includes a limiting rotation part 23, which is disposed on the outer periphery of the supporting rotating shaft 30 and is fixedly connected to the first supporting part 21 and the second supporting part 22.

[0038] The inner wall of the limiting rotation part 23 has a limiting surface 23a, and the end of the display screen 10 near the supporting rotating shaft 30 abuts against the limiting surface 23a to limit the maximum rotation angle of the display screen 10.

[0039] Specifically, the support shaft 30 passes through the base 20, and the lower end of the display screen 10 is rotatably connected to the base 20 through the support shaft 30. The limiting rotation part 23 is arranged around the outer periphery of the support shaft 30, so that the limiting rotation part 23 and the support shaft 30 are arranged coaxially in the axial direction.

[0040] Furthermore, the two ends of the limiting rotation part 23 can be integrally formed and fixedly connected to the first support part 21 and the second support part 22 of the base 20, respectively, so that the limiting rotation part 23 structurally connects the first support part 21 and the second support part 22 into a whole, thereby forming an annular or nearly annular rotation cavity around the support shaft 30. A limiting surface 23a is formed on the inner wall of the rotation cavity to prevent the display screen 10 from continuing to rotate. The end of the display screen 10 near the support shaft 30 is positioned opposite to the inner wall of the limiting rotation part 23. When the display screen 10 rotates around the support shaft 30, this end slides along the inner wall of the limiting rotation part 23. When the display screen 10 rotates to a predetermined maximum forward tilt angle or backward tilt angle, the end of the display screen 10 near the support shaft 30 abuts against the limiting surface 23a, and the limiting surface 23a generates a reverse blocking torque on this end, thereby preventing the display screen 10 from continuing to rotate and limiting the maximum rotation angle of the display screen 10 to a safe range.

[0041] It should be noted that the maximum rotation angle corresponding to the safe range in this embodiment is ensured by the limiting surface 23a of the limiting rotation part 23, so that the vertical projection of the display screen 10 is always within the support area 20a formed by the first support part 21 and the second support part 22 on the bearing surface under all allowed rotation angles, thereby ensuring that the conference room table nameplate can maintain stable support throughout the entire angle adjustment range and will not tilt due to excessive adjustment beyond the support area 20a.

[0042] In one specific embodiment, the base 20 includes an arc-shaped connecting portion 24 that connects the first support portion 21 and the second support portion 22. When viewed along the vertical direction F1, the arc-shaped connecting portion 24 is recessed from the bearing surface along the side facing the display screen 10.

[0043] Specifically, the arc-shaped connecting part 24 is located in the middle area between the two supporting parts. When viewed from above, it together with the first supporting part 21 and the second supporting part 22 forms a supporting area 20a. When viewed from the side or vertical direction F1, it has an arc-shaped transition, connecting the left and right supporting parts of the display screen 10 in terms of thickness into a whole, so that the base 20 forms an integrated frame in terms of structure, which is beneficial to improving the overall rigidity and stress continuity.

[0044] Furthermore, the arc-shaped connecting part 24 is recessed on the side facing the display screen 10, so that the arc-shaped contour is inward towards the display screen 10. In this way, when the display screen 10 tilts forward or backward around the support pivot 30, since the arc-shaped connecting part 24 continuously connects the first support part 21 and the second support part 22 in the left and right directions, when the table card is subjected to an external force from the direction of the display screen 10, the external force is transmitted to the base 20 through the support pivot 30 and can be distributed to the two support parts in the left and right directions along the arc-shaped connecting part 24. This avoids excessive force on one side of the support member and improves the torsional resistance and deformation resistance of the entire base 20.

[0045] Furthermore, the bottom surfaces of the first support portion 21 and the second support portion 22 serve as the main surfaces that fit against the bearing surface, while the lowest edge of the arc-shaped connecting portion 24 is higher than the bearing surface and does not directly contact the tabletop. This makes the middle part of the base 20 appear to be suspended in an arc shape, which reduces the bulkiness of the base 20 on the one hand, and makes it easier to wipe the middle area or pass through the middle area when cleaning the tabletop.

[0046] In one specific embodiment, the base 20 further includes two counterweight areas 25. When viewed along the vertical direction F1, the two counterweight areas 25 are respectively disposed on the first support part 21 and the second support part 22 with the central axis of the support shaft 30 as the axis of symmetry, and are located at both ends of the arc-shaped connecting part 24.

[0047] Specifically, each counterweight zone 25 is composed of dense materials such as metal or composite materials, which can effectively increase the overall weight of the base 20. The two counterweight zones 25 are located at both ends of the arc-shaped connecting part 24. The central axis of the supporting pivot 30 is at the center of the base 20. The base 20 can be divided into left and right parts through this central axis. The two counterweight zones 25 are located on the outer sides of the first support part 21 and the second support part 22, respectively.

[0048] Furthermore, the arrangement of the counterweight area 25 not only increases the weight of the base 20 but also enhances its anti-tipping properties. By increasing the weight of the lower half, it helps maintain the balance of the display screen 10 during rotation. The counterweight area 25, through its connection with the support, makes the support area 20a of the entire base 20 on the bearing surface more stable. Especially when the display screen 10 is adjusted, the counterweight area 25 helps keep the center of gravity of the table sign within the support area 20a, thus preventing the table sign from tipping over due to excessive forward or backward tilting.

[0049] Furthermore, by setting the position of the counterweight area 25 symmetrically, the base 20 is subjected to uniform force. During the forward and backward tilting of the display screen 10, the counterweight area 25 effectively counteracts the unbalanced torque generated by the display screen 10, so that the table card remains stable.

[0050] In one specific embodiment, the base 20 further includes a drive plate 26, which is disposed between the two counterweight areas 25 and on the arc-shaped connecting portion 24; The e-ink conference room nameplate also includes a power interface 27, which is located on the side of the base 20 and is electrically connected to the driver board 26.

[0051] Specifically, the driver board 26 integrates a drive control system for controlling the refresh and updating of the e-ink screen's display content. The power interface 27 is located on the side of the base 20, facilitating connection to an external power source during installation and use. The power interface 27 is connected to the driver board 26 via an electrical connection line, ensuring a stable power supply to the driver board 26 and its internal control system.

[0052] Furthermore, the drive plate 26 is positioned between the counterweight areas 25 and above the arc-shaped connecting portion 24. This design allows the weight distribution of the drive plate 26 to be more evenly distributed in the central area of ​​the base 20. This ensures that the drive plate 26 is located near the center of gravity of the base 20, effectively preventing the base 20 from becoming unbalanced due to improper positioning of the drive plate 26, thus affecting the stability of the table cards.

[0053] In one specific embodiment, the support shaft 30 is a hollow structure, and a wiring channel 31 for threading flexible ribbon cables is provided inside the support shaft 30 to electrically connect the display screen 10 and the drive board 26.

[0054] Specifically, the support hinge 30 is located at the connection point between the base 20 and the display screen 10. The function of the support hinge 30 is to support the rotational movement of the display screen 10 and allow the display screen 10 to rotate around its axis along the thickness direction of the display screen 10. At the same time, the support hinge 30, through its hollow structure design, provides space for the wiring channel 31, allowing the flexible ribbon cable to freely transmit power and control signals between the display screen 10 and the base 20, thereby realizing the electrical connection between the display screen 10 and the driver board 26.

[0055] Furthermore, the rotating support shaft has a locking structure. When the display screen 10 is adjusted, the shaft itself provides sufficient friction to fix the position of the display screen 10 and prevent the display screen 10 from slipping during the adjustment process. After the display screen 10 is adjusted to the required angle, the support shaft 30 can provide the necessary support force so that the display screen 10 remains stable in any position and will not slide or fall off due to gravity or external force.

[0056] In one specific embodiment, the base 20 further includes a first bottom surface 211 and a second bottom surface 221, one end of the arc-shaped connecting part 24 is connected to the first bottom surface 211 and the other end is connected to the second bottom surface 221, and the first bottom surface 211 and the second bottom surface 221 are respectively attached to the bearing surface.

[0057] Specifically, the first bottom surface 211 and the second bottom surface 221 are respectively located on the left and right sides of the base 20, forming support points with the bearing surface. These two bottom surfaces serve as the support surfaces for the first support part 21 and the second support part 22 of the base 20, ensuring that the table sign remains stable when placed. The arc-shaped connecting part 24 forms a connection at the front and rear ends of the base 20, thereby connecting the first support part 21 and the second support part 22 and enhancing the structural integrity of the base 20. The first bottom surface 211 and the second bottom surface 221 of the base 20, through contact with the bearing surface, transfer the weight of the display screen 10 to the bearing surface, thereby providing strong support.

[0058] In one specific embodiment, the base 20 further includes an anti-slip pad 28, which is respectively disposed on the first bottom surface 211 and the second bottom surface 221.

[0059] Specifically, anti-slip pads 28 are disposed on the lower surfaces of the first bottom surface 211 and the second bottom surface 221. These two bottom surfaces are in close contact with the bearing surface, and direct frictional contact is formed between the anti-slip pads 28 and the bearing surface. The placement of the anti-slip pads 28 makes the table sign more stable on the bearing surface, preventing the base 20 from sliding due to external forces or the angle adjustment of the display screen 10. The friction of the anti-slip pads 28 interacts with the bearing surface through its elasticity and material properties, enhancing the adhesion between the base 20 and the bearing surface.

[0060] Furthermore, the anti-slip pads 28 are arranged in areas corresponding to the stress-bearing areas of the base 20, namely the first bottom surface 211 and the second bottom surface 221 of the base 20. By providing anti-slip pads 28 on these two contact surfaces respectively, the anti-slip properties of the nameplate are ensured, and the center of gravity is prevented from shifting due to the sliding of the base 20 when adjusting the display screen 10, thereby further reducing the risk of tipping over.

[0061] Therefore, the aforementioned e-ink conference room nameplate 100, by setting the base 20 with symmetrically extending first support parts 21 and second support parts 22 to form a stable support area 20a, and in conjunction with the centrally located support pivot 30, ensures that the vertical projection of the display screen 10 always falls within the support area 20a when rotated at any angle. This ensures that the center of gravity of the display screen 10 is always limited within the support area 20a of the base 20, thus avoiding the risk of tipping over due to a shift in the center of gravity caused by rotation.

[0062] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
