[0012] Preferably, a control circuit board for controlling the display screen and batteries for power supply are installed inside the bottom shell, and the batteries are four AAA batteries.

[0013] Preferably: the control circuit board is provided with a reset button for restoring the display screen to an initial state.

[0014] Preferably: a cover plate for sealing is installed at the bottom of the bottom shell.

[0015] Preferably, the length of the limiting plate is greater than the width of the vertical shell and less than the length of the through slot.

[0016] Compared with the prior art, the beneficial effect of the utility model is that the rotating shaft is driven to rotate by the knob, so that the limit plate can limit the position of the display screen, so that the display screen can be changed from a vertical state to an inclined state, and can be freely adjusted in different lighting environments to ensure the display effect.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Embodiment 1

[0023] See also Figure 1-3 The utility model provides a technical solution: a new type of electronic seat card, including a bottom shell 1, a vertical shell 2 is installed on the top of the bottom shell 1, and display screens 3 are installed on both sides of the vertical shell 2. Through grooves 8 are symmetrically opened on both sides of the top of the vertical shell 2, and a rotating shaft 6 is rotatably connected inside the through groove 8. A limiting plate 7 for lifting the display screen 3 is installed on the rotating shaft 6.

[0024] like Figure 1 and Figure 2 As shown: the display screen 3 and the top of the stand shell 2 are connected to each other through a damping hinge; through the above arrangement, a certain resistance can be provided when the display screen 3 is rotated, thereby avoiding the display screen 3 from rotating at will and ensuring the stability of the position of the display screen 3.

[0025] like Figure 1 and Figure 2As shown: Display screen 3 is a 7.5-inch electronic ink screen; through the above settings, electricity is needed to change the electric field only when the display screen is updated. In other cases, basically no power loss will be generated, so it is very power-saving.

[0026] like Figure 2 and Figure 3 As shown: one end of the rotating shaft 6 passes through one side of the vertical shell 2 and is installed with a knob 5; through the above arrangement, the rotating shaft 6 can be driven to rotate by the knob 5, thereby causing the limiting plate 7 to rotate.

[0027] like Figure 3 As shown: the shaft 6 is a damping shaft; through the above arrangement, the damping shaft can make the rotation of the limit plate 7 subject to a certain resistance, thereby preventing the limit plate 7 from rotating at will.

[0028] like Figure 1 and Figure 2 As shown: a control circuit board for controlling the display screen 3 and batteries for power supply are installed inside the bottom shell 1, and the batteries are four No. 7 batteries.

[0029] like Figure 1 As shown: a reset button for restoring the display screen 3 to its initial state is provided on the control circuit board; through the above arrangement, a protrusion for pressing the reset button is provided on the cover plate 4, and by long pressing the reset button, the display screen 3 can be restored to its initial state with a QR code.

[0030] like Figure 1 As shown: a cover plate 4 for sealing is installed at the bottom of the bottom shell 1; through the above arrangement, the components inside the bottom shell 1 are limited and fixed.

[0031] like Figure 3 As shown: the length of the limiting plate 7 is greater than the width of the vertical shell 2, and less than the length of the through slot 8; through the above arrangement, after the limiting plate 7 is rotated to the horizontal position, the position of the display screen 3 can be lifted and limited.

[0032] Embodiment 2

[0033] See also Figure 1-3 The utility model provides a technical solution: a new type of electronic seat card, including a bottom shell 1, a vertical shell 2 is installed on the top of the bottom shell 1, and display screens 3 are installed on both sides of the vertical shell 2. Through grooves 8 are symmetrically opened on both sides of the top of the vertical shell 2, and a rotating shaft 6 is rotatably connected inside the through groove 8. A limiting plate 7 for lifting the display screen 3 is installed on the rotating shaft 6.

[0034] The display screen 3 and the bottom of the stand shell 2 are respectively provided with a clamping block and a clamping groove for fixing the position of the display screen 3. The clamping block is installed on the display screen 3, and the clamping groove is installed on the stand shell 2. When the display screen 3 is folded, the clamping block and the clamping groove can cooperate with each other, and then the position of the display screen 3 is fixed, so as to avoid the situation that the position of the display screen 3 is rotated at will.

[0035] Working principle: Connect to the device via the mobile phone Bluetooth, and display the screen to be displayed on the display screen 3. When the angle of the display screen 3 needs to be adjusted, turn the knob 5 to rotate the shaft 6, thereby driving the limit plate 7 to change from a vertical state to a parallel state. Through the interference of the limit plate 7, the position of the display screen 3 can be supported, so that the angle between the display screen 3 and the stand 2 is changed, so that the display screen 3 is in a tilted state, which is convenient for observing the picture.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
