[0002] A table sign, also known as a desk plate, is an identification plate placed on a desktop for displaying or prompting user information. Table signs are widely used, and the application scenarios include but are not limited to meetings, front desk displays, promotions, product introductions, etc. Moreover, the form and structure of table signs are diverse. Table signs are mainly divided into L-shaped table signs, T-shaped table signs, and inverted V-shaped table signs. The inverted V-shaped or L-shaped table signs are mainly of an integrally formed structure. When in use, they are directly placed on the tabletop, and the information paper for display is in an inclined state after being placed.

[0003] After research, it is found that the existing table signs have the following disadvantages:

[0004] Large in size, inconvenient for storage and carrying. Summary of the Invention

For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0036] In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] Currently, in order to facilitate obtaining relevant information, table tents are used more and more frequently, and the usage occasions include but are not limited to meetings, front desk displays, promotions, or product introductions, etc. Generally, table tents include a paper structure or an electronic display screen structure. The information displayed on the electronic display screen structure can be adjusted as needed, which is convenient to use and is used more widely. Existing electronic display table tents are in the shape of "V" or "T", etc., and are directly placed on the desktop. After use, they are large in size and inconvenient to store and carry.

[0038] Please refer to Figures 1-6 , in view of this, the designer designed a double-screen folding electronic table tent, which can adjust the form of the electronic table tent as needed, so as to adjust it to a form with a reduced volume when storing or carrying, and is convenient to store and carry.

[0039] Please refer to Figures 1-3 , in this embodiment, the double-screen folding electronic table tent includes a first display screen group 100, a second display screen group 200, and a circuit board 300; the first display screen group 100 and the second display screen group 200 are rotatably connected, and the two can be switched between a folded state and an open state; the circuit board 300 is disposed on one of the first display screen group 100 and the second display screen group 200, and both the first display screen group 100 and the second display screen group 200 are communicatively connected to the circuit board 300.

[0040] The dual-screen folding electronic nameplate provided in this embodiment has a rotational fit between the first display screen group 100 and the second display screen group 220. During the rotation process, they have a folding state and an open state that switch with each other. When in the folding state, the overall volume is small, making it convenient for storage and carrying. When in the open state, the electronic nameplate is placed on the table, stable and reliable, not easily toppled, and safe to use. Moreover, both the first display screen group 100 and the second display screen group 200 can display corresponding information, that is, corresponding information can be obtained from the first display screen group 100 and the second display screen group 200, thus facilitating observation and making use more convenient.

[0041] In addition, the first display screen group 100 and the second display screen group 200 are independently set, and the information they display can be set as needed, with richer information content and a high experience level.

[0042] At the same time, since both the first display screen group 100 and the second display screen group 200 are connected to the circuit board 300, that is, the two display screen groups share one circuit board 300. In this way, not only is the overall thickness reduced when the electronic nameplate is folded, further reducing the overall volume, but also costs are saved. In other words, for the electronic nameplate provided in this embodiment, both the first display screen group 100 and the second display screen group 200 are connected to the circuit board 300. After folding, the thickness of the electronic nameplate is smaller than that of the structure where each of the two display screen groups uses one circuit board 300, that is, the thickness of one circuit board 300 can be reduced. The electronic nameplate has a small volume, requires little space, and is convenient for storage and carrying. And it is light in weight, reducing the labor intensity of storage and carrying.

[0043] Please refer to Figure 3 , in this embodiment, optionally, the first display screen group 100 includes a first front shell 110, a first display screen 120, a first outer screen 130, a backing plate 140, and a first connecting member 150. The first display screen 120 is connected to the backing plate 140 through the first connecting member 150. Both the backing plate 140 and the first outer screen 130 are connected to the first front shell 110. The first display screen 120 is located between the first outer screen 130 and the backing plate 140. The first display screen 120 is used to display corresponding information, and the information displayed on the first display screen 120 can be observed through the first outer screen 130.

[0044] Please combine Figure 4 and Figure 5, Optionally, the first face shell 110 is set as a rectangular shell. The first face shell 110 includes a rectangular first plate 101, a connecting convex part 102, and two limiting convex parts 103. The first plate 101 has opposite first inner plate surfaces 111 and first outer plate surfaces 112. A rectangular first receiving groove 113 is provided on the first outer plate surface 112. The cushion plate 140 is embedded in the first receiving groove 113 and connected to the bottom wall of the first receiving groove 113. The connecting convex part 102 is provided on the first inner plate surface 111. The connecting convex part 102 protrudes from the first inner plate surface 111 in a direction perpendicular to the first inner plate surface 111. The connecting convex part 102 extends along a preset direction. First assembly holes 1021 are respectively provided at both ends of the connecting convex part 102 in the preset direction. Wherein, the preset direction is the length direction of the first plate 101. The two limiting convex parts 103 are both provided on the connecting convex part 102. The two limiting convex parts 103 have a spacing on the connecting convex part 102 and are symmetrically arranged with the midline of the length direction of the connecting convex part 102 as the axis of symmetry. Each limiting convex part 103 is set as an arc-shaped plate. Each limiting convex part 103 has a spacing from the first inner plate surface 111 of the first plate 101 in the circumferential direction of the connecting convex part 102.

[0045] Further, a first avoiding hole 114 is provided on the first face shell 110. The first avoiding hole 114 penetrates through the bottom wall of the first receiving groove 113 and the connecting convex part 102 at the same time. And the first avoiding hole 114 is located at the middle position of the connecting convex part 102 in its length direction and is located between the two limiting convex parts 103.

[0046] It should be understood that the first connecting member 150 can be set as a sponge pad with an adhesive surface. Both opposite sides of the sponge pad have adhesive surfaces, so as to bond and fix the cushion plate 140 and the first display screen 120. In addition, both the cushion plate 140 and the first protective outer plate can be fixedly connected to the first face shell 110 by means of adhesion.

[0047] In addition, the number of the first connecting members 150 can be set as multiple. The multiple first connecting members 150 are arranged at intervals, so that there is a cavity between the first display screen 120 and the cushion plate 140, which is convenient for heat dissipation. And the overall weight can be reduced.

[0048] Please refer to Figure 3 , In this embodiment, optionally, the second display screen group 200 includes a second face shell 210, a second display screen 220, a second outer screen 230, and a second connecting member 240. The second display screen 220 is clamped between the second face shell 210 and the second outer screen 230. The second face shell 210 is connected to the second display screen 220 through the second connecting member 240. The second display screen 220 is used for displaying relevant information, and the information displayed on the second display screen 220 can be observed through the second outer screen 230.

[0049] Please combine Figure 4 andFigure 6 Optionally, the second housing 210 includes a rectangular second plate 211, a connecting strip 212, and two connecting platforms 213. Both of the two connecting platforms 213 are connected to the second plate 211, and the connecting strip 212 is connected to both of the two connecting platforms 213 and is located between the two connecting platforms 213. Specifically, the second plate 211 has a second inner plate surface 2112 and a second outer plate surface 2113 that are oppositely arranged. The second outer plate surface 2113 is provided with a second receiving groove 2114, and one side of the second outer plate surface 2113 in a preset direction is set as a connecting side 2111. The second receiving groove 2114 is set as a rectangular groove, and the circuit board 300 is embedded in the second receiving groove 2114 and is connected to the bottom wall of the second receiving groove 2114. Both of the two connecting platforms 213 are connected to the connecting side 2111 and are spaced apart in the extending direction of the connecting side 2111. Two ends of the connecting strip 212 are respectively connected to the two connecting platforms 213, and the connecting strip 212 is located on the same side as the second outer plate surface 2113, that is, the connecting strip 212 is closer to the second outer plate surface 2113 than the connecting platforms 213. The connecting strip 212, the connecting side 2111, and the two connecting platforms 213 jointly define a second avoidance hole 201. The second avoidance hole 201 is located at the middle position of the connecting side 2111 in its length direction, and the second avoidance hole 201 communicates with the second receiving groove 2114. The inner end surface of each connecting platform 213 is provided with a second assembly hole 2131, where the inner end surface is the end surface where the two connecting platforms 213 are close to each other, that is, the end surface where the connecting platforms 213 form the second avoidance hole 201.

[0050] When the first display screen group 100 and the second display screen group 200 are rotationally assembled, the first housing 110 and the second housing 210 are rotatably connected. Specifically, the connecting convex portion 102 of the first housing 110 is inserted between the two connecting platforms 213, and the first inner plate surface 111 and the second inner plate surface 2112 are opposite to each other, that is, the first inner plate surface 111 and the second inner plate surface 2112 are located between the first outer plate surface 112 and the second outer plate surface 2113, and the two first assembly holes 1021 on the connecting convex portion 102 respectively communicate with the second assembly holes 2131 on the two connecting platforms 213. A rotating shaft 400 is simultaneously inserted into the corresponding first assembly hole 1021 and second assembly hole 2131. The two rotating shafts 400 are coaxially arranged, and the axis of the rotating shaft 400 extends along the preset direction. In this way, the first housing 110 and the second housing 210 are rotatably matched around the axis of the rotating shaft 400, so that the two display screen groups can be switched between a folded state and an open state. It should be understood that a damping structure can be provided on the rotation to prevent the first display screen group 100 and the second display screen group 200 from freely rotating, and the first display screen group 100 and the second display screen group 200 can be relatively fixed at a set angle, and the structure is more stable.

[0051] In addition, after the first front shell 110 and the second front shell 210 are rotationally engaged, the limiting convex portion 103 on the connecting convex portion 102 extends into the second avoidance hole 201. When the first front shell 110 and the second front shell 210 rotate relative to each other to open, the limiting convex portion 103 can abut against the bottom wall of the second receiving groove 2114, thereby restricting the further rotation of the first front shell 110 and the second front shell 210, achieving the purpose of restricting the rotation angle range of the first front shell 110 and the second front shell 210. At the same time, when the limiting convex portion 103 abuts against the bottom wall, at this time, the included angle between the first display screen group 100 and the second display screen group 200 is the largest. At this time, when the electronic name tag is placed on the desktop, the first display screen group 100 and the second display screen group 200 will not continue to open under the action of gravity, and the stability is high. It should be understood that when the first front shell 110 and the second front shell 210 are folded, the first inner plate surface 111 and the second inner plate surface 2112 are attached, that is, rotated to the limit position of folding. At this time, the volume of the electronic name tag is the smallest.

[0052] It should be understood that the number of the limiting convex portions 103 is not limited to two, and can be set to one or more. In this embodiment, they are not listed one by one.

[0053] It should be understood that the first display screen 120 and the second display screen 220 can both be set as touch screens, and the first outer screen 130 and the second outer screen 230 can both be set as touch films. Obviously, the first display screen group 100 and the second display screen group 200 can be controlled by a button group.

[0054] In this embodiment, optionally, the first display screen 120 is electrically connected to the circuit board 300 through the first conductive member 500, and the second display screen 220 is electrically connected to the circuit board 300 through the second conductive member 600. Both the first conductive member 500 and the second conductive member 600 can be set as FPC flexible flat cables. One end of the first conductive member 500 is electrically connected to the first display screen 120, and the other end passes through the first avoidance hole 114 and the second avoidance hole 201 in sequence and is electrically connected to the circuit board 300 located in the second receiving groove 2114. The circuit board 300 and the second display screen 220 are both located in the second receiving groove 2114, and both ends of the second conductive member 600 are respectively connected to the circuit board 300 and the second display screen 220. Since the first conductive member 500 is set as a flexible member, it can be bent and penetrates through the connecting convex portion 102. Since the connecting convex portion 102 is the rotational connection portion of the first display screen group 100 and the second display screen group 200, the first conductive member 500 is closer to the rotation axis 400 line. When the first display screen group 100 and the second display screen group 200 rotate relative to each other, the first conductive member 500 is not likely to interfere with the first display screen group 100 and the second display screen group 200. The deformation of the first conductive member 500 is small, the force is small, it is not easily damaged, and the cost is saved. At the same time, the first conductive member 500 is hidden in the connecting convex portion 102, and the overall structure of the electronic name tag is more compact.

[0055] In this embodiment, optionally, the dual-screen folding electronic name tag further includes a switch module. The switch module is electrically connected to the circuit board 300. The switch module is used to control the turning on or off of the first display screen group 100 and the second display screen group 200 simultaneously. When in the folded state, the switch module is in an open-circuit state that turns off the first display screen group 100 and the second display screen group 200. When in the open state, the switch module is in a conducting state that turns on the first display screen group 100 and the second display screen group 200. It should be understood that the switch module is set to be linked with the two display screen groups. When the first display screen group 100 and the second display screen group 200 rotate relative to each other and are in the folded state, the switch module automatically turns off the first display screen group 100 and the second display screen group 200. When the first display screen group 100 and the second display screen group 200 are opened, the switch module automatically turns on, so that the first display screen group 100 and the second display screen group 200 are powered on and turned on. When both the first display screen group 100 and the second display screen group 200 are powered on, operations on the first display screen group 100 and the second display screen group 200 can be performed.

[0056] Optionally, the switch module can be set as a magnetic proximity switch.

[0057] In addition, the electronic name tag further includes a power module. The power module can be a rechargeable battery, a dry battery, a lithium battery, etc. The power module is communicatively connected to the circuit board 300. For example, a charging port connected to the power module can be provided on the second housing 210 to charge the power module using the charging port. Obviously, the power module can also be charged using a wireless charging method. When the power module has sufficient power, information can be swiped via Bluetooth to send messages to multiple devices in a mobile phone group. When the power module has insufficient power, information can also be swiped using NFC for display.

[0058] The dual-screen folding electronic name tag provided in this embodiment has a dual-screen display, which is convenient for observing information. It has a foldable state and an open state that can be switched to each other. When in the folded state, it has a small volume and is convenient for storage and carrying. At the same time, the two display screen groups share a circuit board 300, further reducing the volume of the electronic name tag when in the folded state.

[0059] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
