[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a bidirectionally extendable display board, comprising a display board body 1, a fixing block 2 fixedly connected to one side surface of the display board body 1, a lighting lamp 3 fixedly connected to one side surface of the display board body 1, and an extension mechanism 4 provided on the inner side surface of the display board body 1;

[0022] The extension mechanism 4 includes a fixed shaft 41, a first gear 42, a second gear 43, a motor 44, a turntable 45, a rotating groove 46, a fixed plate 47, an extension plate 48 and an adjustment component 49. The inner surface of the display board body 1 is connected with the fixed shaft 41, the outer surface of the fixed shaft 41 is fixedly connected with the first gear 42, the first gear 42 is meshed with the second gear 43, and one side surface of the second gear 43 is connected with the output end of the motor 44. The one side surface of the first gear 42 is fixedly connected with the turntable 45, and the one side surface of the turntable 45 is provided with a rotating groove 46. The inner surface of the rotating groove 46 is rotatably connected with the fixed plate 47, and the one side surface of the fixed plate 47 is fixedly connected with the extension plate 48. One side of the display board body 1 An adjustment component 49 is provided on the surface. Through the arrangement of the fixed shaft 41, the first gear 42, the second gear 43, the motor 44, the turntable 45, the rotating groove 46, the fixed plate 47, and the extension plate 48, when the display board needs to be extended, the motor 44 is started, and the motor 44 drives the second gear 43 to rotate, thereby driving the first gear 42 to rotate, and then the turntable 45 rotates accordingly. The rotating groove 46 on the turntable 45 provides a rotation track for the fixed plate 47, so that the fixed plate 47 can rotate along the track of the rotating groove 46. Since the fixed plate 47 is fixedly connected to the extension plate 48, the extension plate 48 will also expand with the rotation of the fixed plate 47, thereby realizing the two-way extension of the display board in the horizontal direction.

[0023] Furthermore, the adjustment assembly 49 includes an adjustment block 491, a connecting block 492, a cylinder 493, a support column 494 and a pulley 495. The adjustment block 491 is fixedly connected to one side surface of the display board body 1, the connecting block 492 is fixedly connected to one side surface of the adjustment block 491, the output end of the cylinder 493 is fixedly connected to one side surface of the connecting block 492, the outer side surface of the cylinder 493 is fixedly connected to the support column 494, and the lower surface of the support column 494 is provided with a pulley 495. The arrangement of the column 494 and the pulley 495 allows the display board body 1 to rotate around the adjustment block 491 when adjusting the viewing angle of the display board. When the display board body 1 needs to be adjusted in height or angle, the cylinder 493 is started, and the telescopic function of the cylinder will drive the connecting block 492 to move in the vertical direction, thereby driving the display board body 1 to be adjusted vertically. The pulley 495 is provided on the lower surface of the support column 494. These pulleys 495 not only provide smooth movement, but also ensure the stability and smoothness of the entire adjustment process.

[0024] Furthermore, the second gear 43 and the motor 44 form a rotating structure. The rotation of the second gear 43 drives the first gear 42 to rotate. Through the setting of the second gear 43, the first gear 42 is driven to rotate, and then the turntable 45 rotates accordingly, so that the extension plate 48 can be extended.

[0025] Furthermore, four rotating grooves 46 are provided and are arranged in a circular array on one side surface of the turntable 45. The rotating grooves 46 and the fixed plate 47 constitute a rotating structure. Through the setting of the rotating grooves 46, the design of the rotating grooves 46 ensures flexible rotation between the turntable 45 and the fixed plate 47, thereby achieving structural stability and compactness.

[0026] Furthermore, four extension plates 48 are provided and are fixedly connected to the four fixed plates 47. The fixed shaft 41 passes through the turntable 45 and is fixedly connected to the display board body 1. Through the setting of the extension plate 48, the extension plate 48 is slidably connected inside the display board body 1, and can be extended in both directions when the display board needs to be extended.

[0027] Furthermore, the fixed plate 47 is rotatably connected to the rotating groove 46 through a circular shaft at one end. Through the setting of the fixed plate 47, the design of the fixed plate 47 ensures a smooth rotation connection between it and the rotating groove 46, and supports the stable installation of other key components.

[0028] Furthermore, the connecting block 492 and the cylinder 493 form a telescopic structure, and the adjusting block 491 and the display board body 1 form a rotating structure. Through the setting of the cylinder 493, precise displacement adjustment can be performed according to preset parameters or external signals, ensuring the stable display of the display board body at different heights or angles.

[0029] Working principle: When the display board needs to be extended, the motor 44 is started, and the motor 44 drives the second gear 43 to rotate, thereby driving the first gear 42 to rotate, and then the turntable 45 rotates accordingly. The rotating groove 46 on the turntable 45 provides a rotating track for the fixed plate 47, so that the fixed plate 47 can rotate along the track of the rotating groove 46. Since the fixed plate 47 is fixedly connected to the extension plate 48, the extension plate 48 will also expand with the rotation of the fixed plate 47, thereby realizing two-way extension of the display board in the horizontal direction. When adjusting the viewing angle of the display board, manually pulling the display board body 1 can make the display board body 1 rotate around the adjustment block 491. When the display board body 1 needs to be adjusted in height or angle, the cylinder 493 is started. The telescopic function of the cylinder 493 will drive the connecting block 492 to move in the vertical direction, thereby driving the display board body 1 to be adjusted vertically. The lower surface of the support column 494 is provided with a pulley 495. These pulleys not only provide smooth movement, but also ensure the stability and smoothness of the entire adjustment process.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
