[0061] The display screen unit 100 includes a plurality of spliced ​​display screens 110;

[0062] The supporting mechanism 200 is used to support the display screen unit 100; the supporting mechanism 200 is composed of a truss structure, and has high supporting strength and good stability.

[0063] The lifting mechanism 300 is used to drive the display screen unit 100 to rise or fall;

[0064] The folding mechanism 400 is configured to gradually unfold or fold the display screen unit 100 when the lifting mechanism 300 drives the display unit to rise or fall, and has a high degree of intelligence, simple operation, and convenient folding;

[0065] The plurality of guide members 500 are configured to limit the vertical movement of the folding mechanism 400, so that the display screen unit 100 can move vertically up and down, thereby avoiding the shaking of the display screen unit and providing strong stability.

[0066] In this embodiment, the display screen unit 100 is folded and placed in the foundation pit 10 to prevent the display screen unit 100 from being damaged by excessive wind.

[0067] like Figure 7 to Figure 9 As shown, further, the folding mechanism 400 includes:

[0068] Multiple rows of hinge groups are arranged in a sequentially spaced arrangement along a transverse direction;

[0069] Each row of hinge groups includes a plurality of outer half-tooth hinges 410 and a plurality of inner half-tooth hinges 420. The plurality of outer half-tooth hinges 410 and the plurality of inner half-tooth hinges 420 are alternately arranged from top to bottom and sequentially connected between two adjacent display screens 110.

[0070] The outward folding half-tooth hinge 410 is configured to fold two adjacent display screens 110 outward;

[0071] The inwardly folding half-tooth hinge 420 is configured to fold two adjacent display screens 110 inwardly;

[0072] The outer half-tooth hinges 410 in each row of hinge groups move up and down along the corresponding guide members 500 during the process of the display unit rising or falling.

[0073] like Figure 8 As shown, further, the outward-folding half-tooth hinge 410 includes an outward-folding body 411 and two outward-folding connecting arms (412, 412') which are rotatably connected to the outward-folding body 411 and symmetrically arranged up and down, wherein one outward-folding connecting arm 412 is configured to rotate upward from a horizontal position to a vertical position (i.e., rotate between 0° and 90°), and the other outward-folding connecting arm 412' is configured to rotate downward from a horizontal position to a vertical position (i.e., rotate between 0° and 90°), so that two adjacent display screens 110 are unfolded or folded outward.

[0074] Preferably, the outward folding body 411 has rotating wheels 4111 symmetrically arranged in pairs, and the guide member 500 is inserted between the rotating wheels 4111 symmetrically arranged in pairs and rotates with the rotating wheels 4111 in a gap, thereby reducing the friction between the guide member 500 and the rotating wheel 4111, extending the service life of the guide member 500 and the rotating wheel 4111, and avoiding the display screen unit 100 from sliding during the up and down movement of the guide member 500; in this embodiment, a guide opening 414 is formed between the rotating wheels 4111 symmetrically arranged in pairs, through which the guide member 500 can pass.

[0075] Furthermore, the outward folding body 411 also includes an outward folding sub-body 413 rotatably connected thereto, two outward folding connecting arms (412, 412') are rotatably mounted on the outward folding body 411, and two symmetrically arranged rotating wheels 4111 are rotatably mounted on the outward folding sub-body 413. With this structural design, during the lifting and lowering process of the display screen unit 100, the parallelism between the display screen unit 100 and the guide member 500 can be automatically adjusted, thereby avoiding the phenomenon that the friction between the display screen unit 100 and the guide member 500 increases due to the non-parallelism between the display screen unit 100 and the guide member 500 (the distance between the two will increase) during the lifting and lowering process.

[0076] like Figure 7 As shown, in this embodiment, after the display screen unit 100 is folded, the multiple display screens 110 are arranged horizontally from top to bottom, and the multiple outward folding sub-bodies 413 are overlapped in sequence from top to bottom, which plays a role in supporting the display screen 110 and avoiding the phenomenon that one end of the display screen 110 is damaged after being folded.

[0077] like Fig. 9 As shown, further, the inward-folding half-tooth hinge 420 includes an inward-folding body 421 and two inward-folding connecting arms (422, 422') which are rotatably connected to the inward-folding body 421 and symmetrically arranged up and down, wherein one inward-folding connecting arm 422 is configured to rotate upward from a horizontal position to a vertical position (i.e., rotate between 0° and 90°), and the other inward-folding connecting arm 422' is configured to rotate downward from a horizontal position to a vertical position (i.e., rotate between 0° and 90°), so that two adjacent display screens 110 are unfolded or folded inward.

[0078] Thus, the folding mechanism is used to adjust the parallelism between the display screen and the guide member when the display screen is vertically unfolded, and to adjust the verticality between the display screen and the guide member when the display screen is horizontally folded.

[0079] like Figure 7 As shown, in this embodiment, a plurality of inwardly folding bodies 421 are symmetrically arranged from top to bottom, which play a role in supporting the display screen 110 and avoid the phenomenon that the other end of the display screen 110 is damaged after being folded.

The connecting member 320 in this embodiment is preferably a steel wire rope with a large bearing capacity;

[0083] A plurality of storage shafts 330 are configured to be fixedly connected to the other ends of the plurality of connecting members 320 respectively;

[0084] At least one rotating power component 340 is used to drive multiple storage shafts 330 to rotate clockwise or counterclockwise, so that the display screen unit 100 connected to the connecting member 320 moves up or down. In this embodiment, the rotating power component 340 is preferably a rotating motor, and the ratio of the number of rotating motors to the number of storage shafts 330 is preferably 1:5, that is, one rotating motor drives five storage shafts 330 to rotate synchronously, with high power and good stability; in this embodiment, preferably, the storage shaft 330 and the motor shaft of the rotating motor are circumferentially fixed and axially slidably matched, so that the storage shaft 330 can automatically adjust the position of the connecting member 320 wrapped around its periphery, which is beneficial to the stability of the connecting member 320 wrapped around the periphery of the storage shaft 330, thereby improving the accuracy of the rotating motor driving the display screen unit 100 to move up or down.

[0085] The driving controller (not shown) is used to control the rotating power component 340 to rotate according to a set number of circles, direction and speed.

[0086] Furthermore, the lifting mechanism 300 further includes:

[0087] A first sensor (not shown) is used to detect whether the display screen unit 100 is fully unfolded. When the first sensor detects that the display screen unit 100 is in a fully unfolded state, it outputs a fully unfolded state signal to the outside.

[0088] The second sensor (not shown) is used to detect whether the display screen unit 100 is fully folded. When the first sensor detects that the display screen unit 100 is in a fully folded state, it outputs a fully folded state signal to the outside.

[0089] The driving controller controls the rotating power component 340 to stop or start according to the signal fed by the first sensor or the second sensor, and has a high degree of intelligence.

[0090] like Figure 5As shown, preferably, the plurality of guide members 500 are arranged vertically and spaced in sequence along the lateral direction, which can provide guidance and prevent the display screen 110 from sliding, and has strong stability.

[0091] like Figure 4 As shown, further, the lifting and folding display screen device also includes a plurality of tension adjustment components 600, the guide member 500 is preferably a steel wire rope, and the tension adjustment component 600 is used to adjust the tension of the steel wire rope; preferably, the tension adjustment component 600 is arranged horizontally, and the vertically arranged steel wire rope is connected to the tension adjustment component 600 after changing direction through the guide wheel 700.

[0092] The tension adjustment assembly 600 includes a tension adjustment body and screws (620, 620') respectively screwed to the two ends of the tension adjustment body 610, wherein one screw 620 is fixedly connected to a fixed position, and the other screw 620' is hinged to the guide member 500, so that the tension adjustment body rotates relative to the two screws (620, 620'), so that the other screw 620' moves parallel to the tension adjustment body 610 to adjust the tension of the guide member 500, thereby increasing the guiding accuracy of the guide member 500 and facilitating the smooth up and down movement of the external half-tooth hinge 410 along the guide member 500.

[0093] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention.
