The display screen can flexibly update its content, while the support plate provides stability, ensuring the screen can be placed stably on the table. However, existing electronic nameplates are space-consuming and inconvenient to store. Utility Model Content

[0003] In view of this, this application provides an electronic table card to solve the problem of electronic table cards being inconvenient to store.

[0004] The first aspect of this application provides an electronic nameplate, including a display screen and a support plate, wherein a first screen is provided on a first side of the display screen, and the support plate is movably connected to a second side of the display screen;

[0005] The electronic nameplate has a first state and a second state. In the first state, the support plate is used to support the display screen. In the second state, the support plate is attached to the second side of the display screen.

[0006] The beneficial effects of the electronic table sign provided in this application are as follows: The electronic table sign in this application has a first state and a second state. In the first state, the support plate is used to support the display screen to ensure that the display screen can be stably placed on the table. In the second state, the support plate is close to the second side of the display screen to reduce the space occupied by the electronic table sign and facilitate storage. Therefore, the problem of inconvenient storage of electronic table signs is solved.

[0007] In some embodiments, the support plate is detachably connected to the second side of the display screen.

[0008] The beneficial effects of adopting the above technical solution are: by separating the support plate from the display screen, the electronic table card can switch between the first state and the second state; and after the support plate is separated from the display screen, the display screen can also be used independently.

[0010] The beneficial effects of adopting the above technical solution are as follows: the support plate can be detachably connected to the second side of the display screen by magnetic attraction, which is conducive to the separation of the support plate and the display screen, thereby facilitating the switching of the electronic table card between the first and second states.

[0011] In some embodiments, multiple first magnetic elements are arranged at intervals along the length direction of the support plate, and multiple third magnetic elements are arranged at intervals along the length direction of the display screen, with the first magnetic elements and the third magnetic elements arranged in a one-to-one correspondence; and / or, multiple second magnetic elements are arranged at intervals along the length direction of the support plate, and multiple fourth magnetic elements are arranged at intervals along the length direction of the display screen, with the second magnetic elements and the fourth magnetic elements arranged in a one-to-one correspondence.

[0012] The beneficial effects of adopting the above technical solution are: it can ensure the stability of the support plate in supporting the display screen, as well as the stability of the support plate when it is attached to the display screen.

[0013] In some embodiments, the support plate is further provided with a fifth magnetic element, which is located on the same side of the support plate as the second magnetic element, and a sixth magnetic element is further provided on the second side of the display screen; when the electronic table card is in the second state, the fifth magnetic element and the sixth magnetic element are magnetically attracted to each other.

[0014] The beneficial effects of adopting the above technical solution are: by using the magnetic attraction between the second and fourth magnetic components, and the magnetic attraction between the fifth and sixth magnetic components, the stability of the support plate and the display screen when they are attached is further guaranteed.

[0015] In some embodiments, multiple fifth magnetic elements are arranged at intervals along the length of the support plate, and multiple sixth magnetic elements are arranged at intervals along the length of the display screen, with the fifth and sixth magnetic elements arranged in a one-to-one correspondence.

[0016] In some embodiments, the support plate includes a first plate segment and a second plate segment, the first plate segment and the second plate segment are rotatably connected, and the first plate segment is movably connected to the second side of the display screen.

[0017] The beneficial effects of adopting the above technical solution are as follows: Since the first plate segment and the second plate segment are rotatably connected, the support plate can make the display screen be in a vertical position and various tilt positions when supporting the display screen, so as to meet the different usage scenarios of users.

[0018] In some embodiments, the support plate has a photovoltaic cell on the side facing away from the display screen.

[0019] The beneficial effects of adopting the above technical solution are: photovoltaic cells can generate electricity using solar energy to power the lithium battery of the display screen, ensuring that the display screen can be used for a long time without frequent charging, thus improving the user experience.

[0020] In some embodiments, the support plate is provided with an energy storage device connected to the photovoltaic cell.

[0021] The beneficial effects of adopting the above technical solution are: the energy storage device can store the electrical energy generated by the photovoltaic cells to ensure that the display screen can be used for a long time even when there is no sun (cloudy days, rainy days, nights, etc.).

[0022] In some embodiments, a second screen is further provided on the second side of the display screen.

[0023] The beneficial effects of adopting the above technical solution are: information can be displayed on both the first and second sides of the display screen so that people on both sides of the display screen can observe the information.

[0044] An embodiment of the first aspect of this application proposes an electronic nameplate that can serve not only as an electronic nameplate on the table but also as a hanging device at the entrance of a meeting room to display relevant appointments or other information. Please refer to... Figure 1 , Figure 4 and Figure 6 The electronic nameplate 10 includes a display screen 11 and a support plate 12. The first side of the display screen 11 is provided with a first screen 111, and the support plate 12 is movably connected to the second side of the display screen 11. The electronic nameplate 10 has a first state and a second state. In the first state, the support plate 12 is used to support the display screen 11. In the second state, the support plate 12 is close to the second side of the display screen 11.

[0045] The first side of the display screen 11 is provided with a first screen 111, and the support plate 12 is movably connected to the second side of the display screen 11. It can be understood that, in the thickness direction of the display screen 11, the first screen 111 and the support plate 12 are located on opposite sides of the display screen 11. The display screen 11 itself can be equipped with a rechargeable battery, such as a lithium battery.

[0046] Understandably, the first screen 111 can almost completely occupy the first side of the display screen 11, that is, the display screen 11 is a narrow bezel screen.

[0047] Understandably, the first screen 111 can be an e-ink screen, a cholesteric liquid crystal screen, an electrochromic screen, etc. Among them, e-ink screens, cholesteric liquid crystal screens, and electrochromic screens only consume power when updating the image, and consume almost no power when displaying static images, resulting in outstanding battery life.

[0048] The support plate 12 is movably connected to the second side of the display screen 11. Understandably, the support plate 12 can be rotatably connected to the second side of the display screen 11 or detachably connected to the second side of the display screen 11.

[0049] The electronic nameplate 10 has a first state and a second state, meaning that the display screen 11 and the support plate 12 can be transformed into the first state and the second state, respectively. Please refer to... Figure 1 and Figure 4 In the first state, the support plate 12 is used to support the display screen 11; please refer to... Figure 6 In the second state, the support plate 12 is attached to the second side of the display screen 11.

[0050] The beneficial effects of the electronic nameplate 10 provided in this application embodiment are as follows: The electronic nameplate 10 in this application has a first state and a second state. In the first state, the support plate 12 is used to support the display screen 11 to ensure that the display screen 11 can be stably placed on the table. In the second state, the support plate 12 is close to the second side of the display screen 11 to reduce the space occupied by the electronic nameplate 10 and facilitate storage. Therefore, the problem of the electronic nameplate 10 being inconvenient to store is solved.

[0051] In some embodiments, the support plate 12 is detachably connected to the second side of the display screen 11.

[0052] Understandably, the support plate 12 can be magnetically connected to the second side of the display screen 11; or, the support plate 12 can be snapped onto the second side of the display screen 11.

[0053] Based on the above technical solution, by separating the support plate 12 from the display screen 11, the electronic nameplate 10 can switch between the first state and the second state; and after the support plate 12 is separated from the display screen 11, the display screen 11 can also be used independently, for example, it can be hung on the door or the glass of the conference room with the help of tools to display information.

[0054] In other embodiments, the support plate 12 is rotatably connected to the display screen 11, that is, the support plate 12 and the display screen 11 are inseparable.

[0055] Please refer to Figure 2 and Figure 3 In some embodiments, a first magnetic element 1211 and a second magnetic element 1212 are respectively provided on two adjacent sides of the support plate 12, and a third magnetic element 113 and a fourth magnetic element 114 are provided on the second side of the display screen 11; the first magnetic element 1211 and the third magnetic element 113 are magnetically attracted to make the electronic table card 10 in a first state, and the second magnetic element 1212 and the fourth magnetic element 114 are magnetically attracted to make the electronic table card 10 in a second state.

[0056] For example, the first magnetic element 1211 is located on the top surface of the support plate 12, and the second magnetic element 1212 is located on the side of the support plate 12 facing the display screen 11.

[0057] For example, in the height direction of the display screen 11, both the third magnetic element 113 and the fourth magnetic element 114 are located in the middle position of the display screen 11, and the third magnetic element 113 is located below the fourth magnetic element 114. The height direction of the display screen 11 is... Figure 2 in the Y direction.

[0058] In this embodiment, at least one of the first magnetic element 1211 and the third magnetic element 113 is a magnet. For example, the first magnetic element 1211 is a magnet and the third magnetic element 113 is an iron element; or, the first magnetic element 1211 is an iron element and the third magnetic element 113 is a magnet; or, both the first magnetic element 1211 and the third magnetic element 113 are magnets.

[0059] Optionally, the first magnetic element 1211 and the third magnetic element 113 have the same shape. For example, the first magnetic element 1211 and the third magnetic element 113 are both circular, elliptical, rectangular, etc.

[0060] In this embodiment, at least one of the second magnetic element 1212 and the fourth magnetic element 114 is a magnet. For example, the second magnetic element 1212 is a magnet and the fourth magnetic element 114 is an iron element; or, the second magnetic element 1212 is an iron element and the fourth magnetic element 114 is a magnet; or, both the second magnetic element 1212 and the fourth magnetic element 114 are magnets.

[0061] Optionally, the second magnetic element 1212 and the fourth magnetic element 114 have the same shape. For example, the second magnetic element 1212 and the fourth magnetic element 114 are both circular, elliptical, rectangular, etc.

[0062] Based on the above technical solution, the support plate 12 is detachably connected to the second side of the display screen 11 by magnetic attraction, which is conducive to the separation of the support plate 12 and the display screen 11, thereby facilitating the switching of the electronic table sign 10 between the first state and the second state.

[0063] In other embodiments, a first latching member and a second latching member are respectively provided on two adjacent sides of the support plate 12, and a third latching member and a fourth latching member are provided on the second side of the display screen 11; the first latching member and the third latching member are latched together to put the electronic table card 10 in a first state, and the second latching member and the fourth latching member are latched together to put the electronic table card 10 in a second state.

[0064] Please refer to Figure 2 and Figure 3 In some embodiments, multiple first magnetic elements 1211 are arranged at intervals along the length of the support plate 12, and multiple third magnetic elements 113 are arranged at intervals along the length of the display screen 11, with the first magnetic elements 1211 and the third magnetic elements 113 arranged in a one-to-one correspondence. Multiple second magnetic elements 1212 are arranged at intervals along the length of the support plate 12, and multiple fourth magnetic elements 114 are arranged at intervals along the length of the display screen 11, with the second magnetic elements 1212 and the fourth magnetic elements 114 arranged in a one-to-one correspondence.

[0065] Wherein, the length direction of the support plate 12 is Figure 3 In the X direction, the length direction of the display screen 11 is also... Figure 2 The X direction in the equation.

[0066] The first magnetic element 1211 and the third magnetic element 113 are arranged in a one-to-one correspondence, which can be understood as the same number of the first magnetic element 1211 and the third magnetic element 113. For example, the number of the first magnetic element 1211 and the third magnetic element 113 can both be two, three, or four or more.

[0067] When there are two of each of the first magnetic element 1211 and the third magnetic element 113, the two first magnetic elements 1211 are located at both ends of the support plate 12 along the length of the support plate 12, and the two third magnetic elements 113 are located at both ends of the display screen 11 along the length of the display screen 11.

[0068] The second magnetic element 1212 and the fourth magnetic element 114 are arranged in a one-to-one correspondence, which can be understood as the same number of the second magnetic element 1212 and the fourth magnetic element 114. For example, the number of the second magnetic element 1212 and the fourth magnetic element 114 can both be two, three, or four or more.

[0069] When there are two of each of the second magnetic element 1212 and the fourth magnetic element 114, the two second magnetic elements 1212 are located at both ends of the support plate 12 along the length of the support plate 12, and the two fourth magnetic elements 114 are located at both ends of the display screen 11 along the length of the display screen 11.

[0070] Based on the above technical solution, the stability of the support plate 12 when supporting the display screen 11 and the stability of the support plate 12 when it is attached to the display screen 11 can be guaranteed.

[0071] In other embodiments, one of each of the first magnetic element 1211 and the third magnetic element 113 is provided; multiple second magnetic elements 1212 are arranged at intervals along the length of the support plate 12, and multiple fourth magnetic elements 114 are arranged at intervals along the length of the display screen 11, with each second magnetic element 1212 and the fourth magnetic element 114 arranged in a one-to-one correspondence. Alternatively, multiple first magnetic elements 1211 are arranged at intervals along the length of the support plate 12, multiple third magnetic elements 113 are arranged at intervals along the length of the display screen 11, with each first magnetic element 1211 and the third magnetic element 113 arranged in a one-to-one correspondence; one of each of the second magnetic elements 1212 and the fourth magnetic element 114 is provided. Alternatively, one of each of the first magnetic elements 1211 and the third magnetic element 113 is provided, and one of each of the second magnetic elements 1212 and the fourth magnetic element 114 is provided.

[0072] Please refer to Figure 2 and Figure 3 In some embodiments, the support plate 12 is further provided with a fifth magnetic element 1221, which is located on the same side of the support plate 12 as the second magnetic element 1212. The second side of the display screen 11 is further provided with a sixth magnetic element 115. When the electronic table card 10 is in the second state, the fifth magnetic element 1221 and the sixth magnetic element 115 are magnetically attracted.

[0073] For example, in the Y direction, the second magnetic element 1212 and the fifth magnetic element 1221 are respectively located at both ends of the support plate 12, and the second magnetic element 1212 is located above the fifth magnetic element 1221.

[0074] For example, in the Y direction, the sixth magnetic element 115 is located below the third magnetic element 113, and the sixth magnetic element 115 is located at the lower end of the display screen 11.

[0075] In this embodiment, at least one of the fifth magnetic element 1221 and the sixth magnetic element 115 is a magnet. For example, the fifth magnetic element 1221 is a magnet and the sixth magnetic element 115 is an iron element; or, the fifth magnetic element 1221 is an iron element and the sixth magnetic element 115 is a magnet; or, both the fifth magnetic element 1221 and the sixth magnetic element 115 are magnets.

[0076] For example, the fifth magnetic element 1221 and the sixth magnetic element 115 have the same shape. For instance, the fifth magnetic element 1221 and the sixth magnetic element 115 are both circular, elliptical, rectangular, etc.

[0077] Based on the above technical solution, the second magnetic component 1212 and the fourth magnetic component 114 are magnetically attracted, as are the fifth magnetic component 1221 and the sixth magnetic component 115, to further ensure the stability of the support plate 12 when it is attached to the display screen 11.

[0078] In other embodiments, the fifth magnetic element 1221 and the sixth magnetic element 115 may be omitted, and the support plate 12 and the display screen 11 may be attached by relying solely on the magnetic attraction of the second magnetic element 1212 and the fourth magnetic element 114.

[0079] In some embodiments, a plurality of fifth magnetic elements 1221 are arranged at intervals along the length direction of the support plate 12, and a plurality of sixth magnetic elements 115 are arranged at intervals along the length direction of the display screen 11, with the fifth magnetic elements 1221 and the sixth magnetic elements 115 arranged in a one-to-one correspondence.

[0080] The fifth magnetic component 1221 and the sixth magnetic component 115 are arranged in a one-to-one correspondence, which can be understood as the same number of the fifth magnetic component 1221 and the sixth magnetic component 115. For example, the number of the fifth magnetic component 1221 and the sixth magnetic component 115 can both be two, three, or four or more.

[0081] When there are two fifth magnetic elements 1221 and two sixth magnetic elements 115, the two fifth magnetic elements 1221 are located at both ends of the support plate 12 along the length of the support plate 12, and the two sixth magnetic elements 115 are located at both ends of the display screen 11 along the length of the display screen 11.

[0082] In other embodiments, one of each of the fifth magnetic element 1221 and the sixth magnetic element 115 may be provided.

[0083] Please refer to Figure 3 and Figure 4 In some embodiments, the support plate 12 includes a first plate segment 121 and a second plate segment 122, which are rotatably connected, and the first plate segment 121 is movably connected to the second side of the display screen 11.

[0084] For example, the first magnetic element 1211 and the second magnetic element 1212 are both disposed on the first plate segment 121; the fifth magnetic element 1221 is disposed on the second plate segment 122. That is, the first plate segment 121 is magnetically connected to the second side of the display screen 11.

[0085] For example, the first plate segment 121 and the second plate segment 122 are rotatably connected by a pivot.

[0086] For example, please refer to Figure 3 In the Y direction, the size of the first plate segment 121 is smaller than the size of the second plate segment 122.

[0087] Understandably, please refer to Figure 4 The first plate segment 121 and the second plate segment 122 can be arranged in a straight line, that is, the included angle between the first plate segment 121 and the second plate segment 122 is 180°. In this case, the display screen 11 is tilted, and the support plate 12 is perpendicular to the display screen 11. The first plate segment 121 and the second plate segment 122 can also be arranged at a set angle (e.g., greater than 90° and less than 180°) to change the tilt angle of the display screen 11. Please refer to [reference needed]. Figure 5 The display screen 11 is arranged vertically.

[0088] Based on the above technical solution, since the first plate segment 121 and the second plate segment 122 are rotatably connected, the support plate 12 can make the display screen 11 in a vertical position and various tilt positions when supporting the display screen 11 (i.e., when the electronic table card 10 is in the first state) to meet the different usage scenarios of users.

[0089] In other embodiments, the first plate segment 121 and the second plate segment 122 can be fixedly connected or integrally connected. When the support plate 12 supports the display screen 11 (i.e., when the electronic table card 10 is in the first state), the display screen 11 has only a vertical position and a tilted position.

[0090] Please refer to Figures 2 to 4 In some embodiments, a photovoltaic cell 1222 is provided on the side of the support plate 12 facing away from the display screen 11.

[0091] For example, the support plate 12 is provided with a first plug 1213 and a second plug 1214, and the second side of the display screen 11 is provided with a first socket 116 and a second socket 117. When the electronic nameplate 10 is in the first state, the first plug 1213 is plugged into the first socket 116 to enable the photovoltaic cell 1222 to provide power to the display screen 11; please refer to Figure 6 When the electronic table sign 10 is in the second state, the second plug 1214 is plugged into the second socket 117 so that the photovoltaic cell 1222 can provide power to the display screen 11.

[0092] For example, the first plug 1213 and the second plug 1214 are staggered in the X direction, and the first socket 116 and the second socket 117 are staggered in the X direction.

[0093] When the support plate 12 includes a first plate segment 121 and a second plate segment 122, the photovoltaic cell 1222 is disposed on the second plate segment 122, and the first plug 1213 and the second plug 1214 are disposed on the first plate segment 121.

[0094] For example, the photovoltaic cell 1222 can be a flexible photovoltaic cell or a rigid photovoltaic cell. The solar photovoltaic technology can be a third-generation new photovoltaic technology such as perovskite, organic solar energy, or dye sensitization, or it can be a traditional crystalline silicon / amorphous silicon photovoltaic technology or a first- or second-generation photovoltaic technology such as CIGS (copper indium gallium selenide) or CdTe (cadmium telluride).

[0095] Since the support plate 12 is equipped with photovoltaic cells 1222, when the support plate 12 is separated from the display screen 11, the support plate 12 can be used as a mobile charging device with other charging components.

[0096] Based on the above technical solution, the photovoltaic cell 1222 can generate electricity using solar energy to power the lithium battery of the display screen 11, ensuring that the display screen 11 can be used for a long time without frequent charging, thus improving the user experience.

[0097] In other embodiments, the photovoltaic cell 1222 may not be mounted on the support plate 12, but may be mounted on the second side of the display screen 11 and above the support plate 12. In this case, the second screen 112 may not be mounted.

[0098] In some embodiments, the support plate 12 is provided with an energy storage device (not shown) connected to the photovoltaic cell 1222.

[0099] When the support plate 12 includes a first plate segment 121 and a second plate segment 122, the energy storage element is disposed on the first plate segment 121.

[0100] The energy storage device can be a rechargeable battery or a supercapacitor, etc.

[0101] Based on the above technical solution, the energy storage device can store the electrical energy generated by the photovoltaic cell 1222 to ensure that the display screen 11 can be used for a long time even when there is no sun (cloudy days, rainy days, nights, etc.).

[0102] Please refer to Figure 2 In some embodiments, a second screen 112 is also provided on the second side of the display screen 11. That is, in the thickness direction of the display screen 11, the first screen 111 and the second screen 112 are located on opposite sides of the display screen 11.

[0103] The size of the second screen 112 is smaller than that of the first screen 111.

[0104] For example, in the Y direction, the second screen 112 is positioned above the support plate 12.

[0105] Based on the above technical solution, information can be displayed on both the first and second sides of the display screen 11 so that people on both sides of the display screen 11 can observe the information. For example, when the display screen 11 is hung on a door, people inside and outside the door can observe the information displayed on the display screen 11.

[0106] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
