[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1 like Figures 1 to 8 As shown, a multi-angle display device for graphic design according to an embodiment of the present invention includes a display board 1, on which a shading component is provided. The shading component includes a light sensor 21, which is fixed to the bottom of one side of the display board 1. A shading plate 314 is provided on one side of the display board 1. The light sensor 21 detects the light intensity. When the light is strong, the flip component is driven to flip the adjustment component together, so that the shading plate 314 flips to the other side of the display board 1, thereby blocking the poster.

[0025] Specifically, the existing technology still has some shortcomings in actual use. Since outdoor light is provided by sunlight, the light will continue to change over time. When the light is strong, it is easy to form mirror reflection on the surface of the poster, resulting in local overbrightness and reflection. The reflective area appears as a bright white area, making it difficult for the audience to see the content of the poster clearly.

[0026] Therefore, the present invention solves this problem by providing a corresponding structure. During outdoor exhibitions, the light intensity is detected by the light sensor 21. When the light is strong, the flip assembly is driven to flip the adjustment assembly together, so that the shading plate 314 is flipped to the other side of the display board 1. When light shines on the shading plate 314, most of the light will be reflected or absorbed, and a small amount of light will penetrate the shading plate 314 and shine on the display board 1, thereby achieving a light shielding effect and avoiding the problem of reflection in local areas of the poster.

[0027] Example 2 like Figures 2 to 8As shown, the comparative example one, another embodiment of the present application is: As shown, Figures 2 to 4 The light shielding assembly of the present embodiment is composed of a turnover part and an adjusting part. The turnover part includes two symmetrical support frames 22 fixed at the top end of the display board 1. One end of each support frame 22 is fixedly connected with a driving motor 23. A rotating rod 24 is rotatably connected between the two support frames 22. The surface of the rotating rod 24 is fixedly connected with symmetrical guide blocks 25. One guide block 25 is fixedly connected with a contact one 26 at the top. The display board 1 is fixedly connected with a contact two 27 at the top. The contact two 27 is located on the same side as the contact one 26. One end of each contact two 27 is fixedly connected with a guide plate 28. The positions of the contact one 26 and the contact two 27 correspond to each other, so that the contact one 26 and the contact two 27 abut after the guide block 25 is turned over.

[0028] Specifically, the output end of the driving motor 23 is fixed to one end of the rotating rod 24. Initially, the guide plate 28 is located at the back of the display side of the display board 1. When the light is strong, the output end of the driving motor 23 is rotated by one hundred and eighty degrees. The rotating rod 24 is driven to rotate by the output end of the driving motor 23, so that the guide block 25 is turned over by one hundred and eighty degrees around the rotating rod 24 as the axis. At the same time, the contact one 26 and the contact two 27 abut, and the guide plate 28 moves to the display side of the display board 1.

[0029] As shown, Figure 2 , Figure 3 , Figure 5 and Figure 6 The adjusting part of the present embodiment is composed of a clamping device and a locking device. The clamping device includes a guide groove one 31 opened in the guide plate 28. A T-shaped block 32 is slidably connected in the guide groove one 31. The T-shaped block 32 is composed of a horizontal block and a vertical block. The bottom of the horizontal block is fixed to the top of the vertical block. A plurality of rolling balls 33 are symmetrically and rollingly connected to the bottom of the horizontal block. A fixed plate 34 is fixedly connected to the bottom of the vertical block. An abutting groove 35 is opened through the horizontal block. The clamping device is symmetrically arranged. The light shielding plate 314 abuts between the two fixed plates 34. By moving the fixed plate 34, the fixed plate 34 can clamp the light shielding plate 314 of different sizes. By moving the two fixed plates 34 after clamping the light shielding plate 314, the two fixed plates 34 can be moved synchronously, so as to adjust the position of the light shielding plate 314 shielding the display board 1. The rolling balls 33 roll in the guide groove one 31, which is used to reduce the friction generated by the sliding of the T-shaped block 32, so that the T-shaped block 32 moves smoothly.

[0030] Specifically, multiple posters are often displayed on the display board 1. Because some posters are made of materials with reflective properties, and the light-colored areas of light-colored posters are light-transmissive, when strong light shines on them, they will reflect light, affecting the viewing effect. If the shading plate 314 is used to block the entire area of ​​the display side of the display board 1, the parts of the posters that do not have the above characteristics will be blocked by the shading plate 314, so that less light shines on them, making them dim and reducing the viewing experience. The display board 1 is composed of glass, a placement board and a baffle. The side from which the audience looks at the poster placed on the placement board through the glass is the display side, and the side where the baffle is located is the back side of the display side. Therefore, before using this multi-angle display device, first place the easily reflective poster in the same area so that the length of the area is the same as the length of the display side, then place a shading plate 314 of a size sufficient to block this area in one fixed plate 34, then move the other fixed plate 34 so that the two fixed plates 34 clamp the shading plate 314, and then move the two fixed plates 34 synchronously so that the shading plate 314 is on the back of the area that needs to be blocked on the display side.

[0031] When the light sensor 21 detects that the light is strong, the present invention drives the output end of the driving motor 23 to rotate 180 degrees, causing the guide block 25 to flip 180 degrees with the rotating rod 24 as the axis, so that the contact 1 26 and the contact 2 27 abut against each other, and at the same time, the shading plate 314 is flipped to the display side of the display board 1 to achieve the shading effect, avoid the problem of reflection in local areas of the poster, and improve the viewing experience.

[0032] like Figures 5 to 7 As shown, the locking device of this embodiment includes a fixed rod 38 fixed in the guide groove 31, one end of the fixed rod 38 is rotatably connected to the rotating column 36, and the rotating column 36 is rotatably arranged at one end of the guide plate 28. The fixed rod 38 passes through the two abutment grooves 35, and the rotating column 36 has a plurality of arcuate grooves 37 formed in the rotating column 36. The fixed rod 38 has a plurality of straight grooves 39 formed in the fixed rod 38. A plurality of contraction grooves 310 are formed on the surface of the fixed rod 38, and each straight groove 39 is connected to an arcuate groove 37 and a contraction groove 310. A guide rod 311 is slidably connected in each straight groove 39, one end of the guide rod 311 slides in the arc groove 37, a moving plate 312 is fixedly connected to the surface of the guide rod 311, the moving plate 312 slides in the contraction groove 310, and one end of the moving plate 312 is fixedly connected to the arc plate 313. When the rotating column 36 rotates, the guiding action of the arc groove 37 and the straight groove 39 causes the guide rod 311 to move in the direction away from the fixed rod 38, thereby driving the arc plate 313 to expand outward, so that the arc plate 313 abuts against the inner wall of the abutment groove 35.

[0033] Specifically, initially, the arc-shaped plate 313 is in a contracted state, when the light shielding plate 314 is at the back of the area to be shielded on the display side, at this time, the rotating column 36 is rotated, the guide rod 311 is moved away from the fixed rod 38 through the guiding effect of the arc-shaped slot 37 and the straight slot 39, so as to drive the arc-shaped plate 313 to expand outward, and the arc-shaped plate 313 abuts against the inner wall of the abutting slot 35, at this time, the T-shaped block 32 is relatively fixed and will not slide.

[0034] The two fixed plates 34 are moved to clamp the light shielding plate 314 with different widths, and the fixed plates 34 are synchronously moved to drive the clamped light shielding plate 314 to move, so that the light shielding plate 314 is at the back of the area to be shielded on the display side, then the rotating column 36 is rotated, the guide rod 311 is moved away from the fixed rod 38 through the guiding effect of the arc-shaped slot 37 and the straight slot 39, so as to drive the arc-shaped plate 313 to expand outward, and the arc-shaped plate 313 abuts against the inner wall of the abutting slot 35, so that the T-shaped block 32 is relatively fixed and will not slide, and then the light shielding plate 314 will not slide at this time, so as to ensure that the light shielding plate 314 can shield the poster after being turned over.

[0035] As shown in the drawings, Figure 5 As shown in the drawings, Figure 8 The cleaning assembly is arranged on one side of the display board 1, and the cleaning assembly comprises a guide slot two 41, the guide slot two 41 is arranged on the top of the guide plate 28, a lead screw 42 is rotatably connected in the guide slot two 41, a stepping motor 43 is fixedly connected above the rotating column 36, a U-shaped plate 44 is slidably connected in the guide slot two 41, the U-shaped plate 44 is composed of a horizontal rod and two vertical rods, the two vertical rods are fixedly connected to the two ends of the horizontal rod, the horizontal rod is threadedly connected with the lead screw 42, and a sponge block 45 is fixedly connected to the bottom of each vertical rod. The fixed plate 34 is arranged in the two vertical rods of the U-shaped plate 44, the two sponge blocks 45 abut against the two sides of the light shielding plate 314, the U-shaped plate 44 drives the sponge blocks 45 to move by driving the lead screw 42 to rotate, and the fingerprints and dust on the surface of the light shielding plate 314 and the display board 1 are cleaned, and the U-shaped plate 44 will not be stuck with the fixed plate 34 when moving.

[0036] Specifically, initially, the U-shaped plate 44 is arranged at one end of the display board 1. When the audience adjusts the angle of the display board 1 on the multi-angle display device, the glass on the display side of the display board 1 will be touched, the fingerprints on the hands of the audience will be left on the surface of the glass after adjusting the angle of the display board 1, and the outdoor air contains dust, and part of the dust will be attached to the glass on the display side in a long display process, the fingerprints and dust will blur part of the content of the poster, so that the audience cannot clearly see the information on the poster. Therefore, when the contact one 26 and the contact two 27 abut, the light shield plate 314 is at the display side and blocks the poster, at this time, the driving step motor 43 makes the output end intermittent positive and negative rotation, thereby driving the lead screw 42 to move, when it rotates, the U-shaped plate 44 moves to the direction of the other end of the display plate 1, thereby driving the sponge block 45 to clean the two sides of the light shield plate 314 and the display side glass of the display plate 1; When it rotates in the direction, through the above operation, it is cleaned and reset, at this time, the step motor 43 stops moving, and is started again after a period of time, so as to reciprocate until the contact one 26 and the contact two 27 no longer abut.

[0037] The present application drives the step motor 43 to make the output end intermittent positive and negative rotation through the abutment of the contact one 26 and the contact two 27, so as to drive the lead screw 42 to move and drive the sponge block 45 to clean the two sides of the light shield plate 314 and the display side glass of the display plate 1, so that the light shield plate 314 and the display side glass of the display plate 1 are kept clean, and the viewing experience of the audience is further improved.

[0038] Working principle: In outdoor exhibition, first, the poster easy to reflect light is placed in the same area, the length of the area is the same as the length of the display side, then the light shield plate 314 with a size sufficient to block the area is placed in a fixed plate 34, then the other fixed plate 34 is moved, so that the two fixed plates 34 clamp the light shield plate 314, then the two fixed plates 34 are synchronously moved, so that the light shield plate 314 is at the back of the area to be blocked on the display side; At this time, the rotating column 36 is rotated, the guide rod 311 moves away from the fixed rod 38 through the guiding effect of the arc-shaped groove 37 and the straight groove 39, thereby driving the arc-shaped plate 313 to expand outward, so that the arc-shaped plate 313 abuts against the inner wall of the abutment groove 35, at this time, the T-shaped block 32 is relatively fixed and will not slide; Then, the photosensitive sensor 21 is started, when the photosensitive sensor 21 detects that the light is strong, the output end of the driving motor 23 is driven to rotate one hundred and eighty degrees, so that the guide block 25 is flipped one hundred and eighty degrees around the rotating rod 24, so that the contact one 26 and the contact two 27 abut at the same time, and the light shield plate 314 is flipped to the display side of the display plate 1, so as to achieve the effect of light shielding; At this time, the rotating column 36 is rotated, the guide rod 311 moves away from the fixed rod 38 through the guiding effect of the arc-shaped groove 37 and the straight groove 39, thereby driving the arc-shaped plate 313 to expand outward, so that the arc-shaped plate 313 abuts against the inner wall of the abutment groove 35, at this time, the T-shaped block 32 is relatively fixed and will not slide; When the contact one 26 and the contact two 27 abut, the light shield 314 is in the display side and blocks the poster, at this time the driving step motor 43 makes its output end intermittent positive and negative rotation, thus driving the screw rod 42 to move, when it rotates, makes the U-shaped plate 44 move to the direction of the other end of the display board 1, thus driving the sponge block 45 to clean the both sides of the light shield 314 and the display side glass of the display board 1; When its direction rotates, through the above operation, it cleans and resets, at this time the step motor 43 stops moving, after a period of time, it is started again, so reciprocate; When the photosensitive sensor 21 detects that the light intensity is not enough to make the poster reflect light, through the above operation, the light shield 314 resets, at this time the contact one 26 and the contact two 27 no longer abut, the step motor 43 is closed.
