[0002] Display boards, also called exhibition boards, refer to plate-like media used to publish and display information. They are made of paper, new materials, metal, etc. For example, if a company wants to increase the popularity of its products, display boards will become one of the most common ways of publicity. With the development of information technology, display boards are gradually being displayed in the form of smart displays. Smart displays can display exhibits through videos or pictures, making the exhibits more vivid in front of visitors.

[0003] In the published Chinese patent application, the publication number is CN214839668U, and the patent name is: a multifunctional display board for an exhibition hall. Although, through the setting of the display stand, the slider and the electric push rod, the conventional display board only plays the effect of flat display of the product, but the flat display lacks the attraction brought by the physical display to a certain extent. Therefore, the role of the display stand is to physically display small physical objects and large physical models, which is more comprehensive while cooperating with the flat display, and the role of the electric push rod and the slider is to facilitate the lifting and folding of the display stand and the physical model, thereby playing the role of storing the product. However, the prior art uses a triangular structure to fix the second display screen and the third display screen, and the inclination angle of the second display screen and the third display screen cannot be adjusted. Since the exhibition hall holds activities for different audiences of tourists, some of the audience tourists are primary and secondary school students, and some of the audience tourists are middle-aged and elderly people. There are differences in the height of the audience tourists, resulting in different viewing angles of the display board. Therefore, it is necessary to design an adjustable angle display board for tourists of different heights, so as to meet the exhibition experience of different audience tourists.

[0004] In summary, in order to solve the problems existing in the prior art, this case is proposed to solve them. Utility Model Content

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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0026] For example, see Figures 1 to 4 The utility model provides a technical solution: a digital information display board for an exhibition hall, comprising a support box 1, a base 2, and a display screen 14. The base 2 is rotatably arranged at the upper end of the support box 1. A third motor is arranged inside the support box 1, and an output shaft of the third motor is fixedly connected to the base 2. Two parallel first slide grooves 3 are provided on the base 2, and a tilting assembly is arranged in the two first slide grooves 3, and the display screen 14 is arranged on the tilting assembly.

[0027] The support box 1 is used to support the base 2. The third motor is used to drive the base 2 to rotate a certain angle. After the base 2 rotates a certain angle, it drives the display screen 14 to rotate, thereby changing the orientation of the display screen 14. The tilting component is used to adjust the tilting angle of the display screen 14.

[0028] The tilting assembly includes a first support rod 9, a second support rod 12, and a swing rod 10. The upper end of the second support rod 12 is rotatably set on a lower side wall of the display screen 14 through a second rotating shaft 13, and the upper end of the swing rod 10 is rotatably set on a middle side wall of the display screen 14 through a first rotating shaft 11; the lower end of the swing rod 10 is hinged to the upper end of the first support rod 9.

[0029] When the first support rod 9 and the second support rod 12 are close to each other, the first support rod 9 pushes the upper part of the display screen 14 to rotate clockwise around the second rotation axis 13 by a certain angle through the swing rod 10, so that the inclination slope of the display screen 14 is steeper. When the first support rod 9 and the second support rod 12 are away from each other, the first support rod 9 pulls the upper part of the display screen 14 to rotate counterclockwise around the second rotation axis 13 by a certain angle through the swing rod 10, so that the inclination slope of the display screen 14 is gentle.

[0030] Specifically, the tilting assembly further includes a first motor 7, a gear 8, a first rack 5, and a second rack 6; the first rack 5 and the second rack 6 are slidably arranged on the base 2 and located in the first slide slot 3, the upper end of the first rack 5 is fixedly connected to the lower end of the first support rod 9, and the upper end of the second rack 6 is fixedly connected to the lower end of the second support rod 12. The gear 8 is rotatably arranged in the first slide slot 3, and the teeth of the gear 8 are respectively meshed with the first rack 5 and the second rack 6, the first motor 7 is embeddedly installed on the base 2, and the output shaft end of the first motor 7 is fixedly connected to the central axis of the gear 8.

[0031] The first motor 7 is used to drive the gear 8 to rotate, and the rotation of the gear 8 drives the first rack 5 and the second rack 6 to move toward or away from each other. When the first rack 5 and the second rack 6 move toward each other, the first rack 5 drives the first support rod 9 to move toward the side where the second support rod 12 is located, and the second rack 6 drives the second support rod 12 to move toward the side where the first support rod 9 is located, so that the first support rod 9 and the second support rod 12 are close to each other. When the first rack 5 and the second rack 6 move away from each other, the first rack 5 drives the first support rod 9 to move away from the second support rod 12, and the second rack 6 drives the second support rod 12 to move away from the first support rod 9, so that the first support rod 9 and the second support rod 12 are away from each other.

[0032] When in use, the device is first placed at a suitable position in the exhibition tube, and then the third motor is started, the third motor drives the base 2 to rotate a certain angle, and the base 2 drives the display screen 14 to rotate, and adjusts the display angle of the display screen 14 in the horizontal direction. Then the first motor 7 is started, and the first motor 7 drives the first rack 5 and the second rack 6 to move through the gear 8, so that the first support rod 9 and the second support rod 12 are close to or away from each other. When they are close to each other, the first support rod 9 pushes the first rotating shaft 11 to move upward through the swing rod 10, and the second support rod 12 pushes the second rotating shaft 13 to move below the first rotating shaft 11, so as to quickly stand up the display screen 14. On the contrary, the display screen 14 can be quickly laid flat, and the adjustment speed of the vertical angle of the display screen 14 is accelerated by moving the middle and lower parts of the display screen 14 at the same time.

[0033] When display is not needed, the first motor 7 can be started, and the first motor 7 drives the first rack 5 and the second rack 6 to move away from each other, so that the first support rod 9 and the second support rod 12 respectively drive the first rotating shaft 11 and the second rotating shaft 13 to move away from each other, and the display screen 14 will gradually rotate to a horizontal state, so as to store the display board.

[0034] For example 2, please refer to Figure 5 The difference between this embodiment and the first embodiment is that the tilting assembly further includes a second motor 15 and a screw rod 16. The screw rod 16 is arranged in the first slide groove 3 and is rotatably connected to the base 2. The second motor 15 is fixedly installed in the first slide groove 3 of the base 2, and the output shaft of the second motor 15 is transmission-connected to the screw rod 16. The outer wall of the screw rod 16 is engraved with two threaded areas with thread patterns facing each other. A slider 17 is threadedly connected to the two threaded areas of the screw rod 16, and the two sliders 17 are slidably connected to the base 2 through the first slide groove 3. One slider 17 is fixedly connected to the lower end of the first support rod 9, and the other slider 17 is fixedly connected to the lower end of the second support rod 12.

[0035] The second motor 15 is used to drive the screw rod 16 to rotate clockwise or counterclockwise, and the screw rod 16 rotates to drive the two sliders 17 located thereon to slide, and the two sliders 17 move closer to or farther away from each other. When the two sliders 17 move toward each other, the two sliders 17 respectively drive the first support rod 9 and the second support rod 12 to move closer to each other. When the two sliders 17 move away from each other, the two sliders 17 respectively drive the first support rod 9 and the second support rod 12 to move away from each other.

[0036] When in use, the second motor 15 drives the screw rod 16 to rotate, so that the threads on the screw rod 16 that rotate in opposite directions drive the two sliders 17 to move closer to or away from each other, so as to adjust the position of the first support rod 9 and the second support rod 12, complete the adjustment of the vertical angle of the display screen 14 or complete the storage of the display screen 14.
