DETAILED DESCRIPTION

[0060] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0061] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0062] Embodiment 1: A smart liquid crystal display, such as Figure 1-7 As shown, it includes a base 1, a fixed seat 45 is fixed on the base 1 through a bracket, a first frame 7 is installed on the fixed seat 45, a mounting shaft is rotatably installed at the bottom of the fixed seat 45, a driven frame 26 is installed on the mounting shaft, one end of the driven frame 26 is connected to a base assembly, a second frame 6 is installed on the base assembly, and a deflection control assembly for controlling the rotation of the driven frame 26 is provided at the bottom of the fixed seat 45; display bodies 5 are installed in both the first frame 7 and the second frame 6; each display body 5 realizes the switching of display modes through the display control system;

[0063] The display control system comprises:

[0064] Position detection module, the position detection module is installed on the first frame 7 and the second frame 6, and is used to detect the positions of the display bodies 5 on both sides;

[0065] A control module, which performs corresponding control based on the signal fed back by the position detection module;

[0066] A mode switching module, which switches each display body 5 to a preset mode such as changing the display screen of the display body 5 according to the control instruction of the control module;

[0067] Wherein, the position detection module comprises:

[0068] A first annular plate 16, which is mounted on both sides of the top of the first frame 7;

[0069] A central column 19, the central column 19 is fixed to the top of the second frame 6 near the first annular plate 16, and a plurality of circumferentially distributed contact switches 20 are arranged on the outer side of the central column 19, and the electrical signals of the contact switches 20 are transmitted to the control module;

[0070] The second annular plate 18 is fixed to the top of the second frame 6, the central column 19 is located at the center of the second annular plate 18, and an opening adapted to the position of the contact switch 20 is opened on the annular surface of the second annular plate 18;

[0071] A side bracket 21, the side bracket 21 is fixed to the side of the center column 19, a sliding column 22 is slidably connected in the side bracket 21, the sliding column 22 is connected to the side bracket 21 through the first spring 17, one end of the sliding column 22 is adapted to the contact switch 20, and an arc head 23 is arranged after the end of the sliding column 22 away from the contact switch 20 passes through the opening;

[0072] The installation axis coincides with the center of the first annular plate 16. When the second frame 6 rotates based on the installation axis, the second annular plate 18 moves along the annular surface of the first annular plate 16. When the arc head 23 is squeezed into the opening by the first annular plate 16, one end of the sliding column 22 presses and triggers the corresponding contact switch 20.

[0073] By setting three display bodies 5, etc., a triple screen structure is formed. Since the second frames 6 on both sides can be deflected, the content can be better displayed. Since a display control system is set, the design of multiple arc heads 23 and contact switches 20 can automatically switch modes based on the deflection angle of the second frame 6;

[0074] For example, when the second frames 6 on both sides are retracted inward, the three display bodies 5 can divide the same picture into three parts for synchronous display, thereby improving the viewing effect; when the second frames 6 on both sides are located in the same plane, the three display bodies 5 can display different picture contents and display richer information content; when the second frames 6 on both sides are deflected toward the back of the first frame 7, for example, the three display bodies 5 form a triangle-like structure. At this time, the three display bodies 5 can repeatedly display the same picture and display the same content, thereby realizing a 360° comprehensive display; it is flexible to use and meets the usage requirements of different situations.

[0075] To adjust the angle; Figure 4 As shown, the deflection control assembly includes:

[0076] Angle adjustment motor 29, the angle adjustment motor 29 is installed at the bottom of the fixing seat 45 through a motor seat;

[0077] A driving gear 24, the shaft of which is drivingly connected to the output end of the angle adjustment motor 29, and an outer side of one end of the driven frame 26 is an arc surface structure, on which convex teeth are evenly distributed, and the driving gear 24 meshes with the convex teeth;

[0078] By setting up the deflection control component, the motor 29 can be adjusted to work based on the angle, and the driven frame 26 can be driven to rotate by the driving gear 24 to achieve angle adjustment.

[0079] In order to facilitate the adjustment of the position of the second frame 6; Figure 2 , Figure 5 As shown, the base assembly includes:

[0083] A translation drive assembly, which is mounted on the translation slide rail 27 and is used to drive the first translation seat 39 to translate in the translation slide rail 27;

[0084] By setting the base assembly and the translation drive assembly, the position of the first translation seat 39 on the translation slide rail 27 can be adjusted according to the needs, and then the position of the display bodies 5 on both sides can be adjusted, which improves the practicality;

[0085] Among them, when each contact switch 20 is not triggered, it can also be displayed as a mode to facilitate more reasonable control of the display body 5;

[0086] In addition, the display control system can further include a numbering module, which numbers the contact switches 20, selects a contact switch 20 as No. 1, and numbers them 3, 5, 7, ..., 2n+1 in a clockwise or counterclockwise direction; wherein, the gap between No. 1 and No. 3 is numbered as No. 2 because no contact switch 20 is triggered, and so on, the gaps are numbered as 2, 4, 6, ..., 2n respectively; each number can correspond to a mode to achieve richer mode switching;

When the second translation base 38 is limited by the stop frame 37, the outer wall of the second annular plate 18 is in close contact with the outer wall of the first annular plate 16;

[0092] By arranging structures such as the second translation base 38 and the stop frame 37, the position of the second translation base 38 can be more accurately restricted, so that the first annular plate 16 and the second annular plate 18 can accurately contact, avoiding collision due to excessive movement and improving reliability.
