It usually refers to a group of people who gather at a designated time and place through the Internet or text messages, etc., and then jointly perform specific actions, such as clapping hands, shouting slogans, etc., and then quickly leave. This form of performance art is called "flash mob action" or "flash mob video". Its main characteristics are that there is only an initiator without an organizer, the members do not know each other, the action is disciplined and short-lived.
[0003] During the flash mob activity, the display rack needs to be quickly deployed and retracted to adapt to the rhythm of the flash mob activity. At present, when the deployable display device is in use, it needs to be manually assembled and retracted, with low efficiency, and cannot well adapt to the rhythm of the flash mob activity. Moreover, before and after the display, the screen of the display screen cannot be cleaned in time, which easily leads to dust accumulation on the screen and affects the viewing effect. In view of the above problems, the inventor proposes a flash deployable display device to solve the above problems. Summary of the Invention
[0004] In order to solve the problem that when the deployable display device is in use at present, it needs to be manually assembled and retracted, with low efficiency and cannot well adapt to the rhythm of the flash mob activity; the purpose of the present invention is to provide a flash deployable display device.
[0005] To solve the above technical problems, the present invention adopts the following technical scheme: A flash deployable display device, including a storage component, the storage component includes a storage box, a driving component and a display component are arranged inside the storage box, the driving component is matched with the display component, the display component includes a display board, an LED display screen is arranged on the side wall of the display board, a cleaning component is arranged on one side of the driving component, and the cleaning component corresponds to and is matched with the LED display screen.
[0006] Preferably, a notch is provided through the top surface of the storage box. Handles are fixedly connected to both side surfaces of the storage box. A boss is fixedly connected to the inner sidewall of the storage box. When the display rack does not need to be displayed, the display rack can be stored in the storage box. The handles facilitate the lifting and transporting of the device. The lifting plate is inserted into the boss, and the lifting plate is slidably connected to the boss. The driving assembly includes a motor. A worm and a synchronous pulley are fixedly connected to the output shaft end of the motor. A synchronous belt is provided on the sidewall of the synchronous pulley. A worm gear is meshed with the sidewall of the worm. A horizontal shaft is fixedly connected through the middle of the sidewall of the worm gear. A transmission gear is fixedly connected to the sidewall of the horizontal shaft and on one side of the worm gear. A toothed plate is meshed with the sidewall of the transmission gear. A convex plate is fixedly connected to the side of the toothed plate facing away from the transmission gear. A first guide plate is fixedly connected to the sidewall of the convex plate. A first cavity plate is fixedly connected to the inner sidewall of the storage box. The first guide plate corresponds to and is slidably connected to the first cavity plate. When the display rack needs to be unfolded during a flash activity, the motor is started. The worm rotates under the action of the motor output shaft. Through the meshing of the worm and the worm gear, the horizontal shaft can be rotated, and then the transmission gear can be rotated. Through the meshing of the transmission gear and the toothed plate, and with the cooperation of the first guide plate and the first cavity plate, the convex plate can be lifted. The side of the convex plate facing away from the toothed plate is fixedly connected to the sidewall of the display board. Therefore, when the convex plate is lifted, the display board can be driven to rise so that the display board can be moved out of the storage box for display. As Figure 4 shown, when the motor is started, the synchronous pulley rotates under the action of the motor output shaft. Through the synchronous belt, another synchronous pulley can be rotated.
[0007] Preferably, a base is provided on the side wall of the motor. The base is fixedly connected to the side wall of the boss. A first bevel gear is fixedly sleeved on the output shaft of the motor. A second bevel gear is meshed with the side wall of the first bevel gear. A transmission shaft is fixedly connected through the middle of the side wall of the second bevel gear. A support plate is rotatably connected to the side wall of the transmission shaft, and the side wall of the support plate is fixedly connected to the side wall of the boss. The end of the transmission shaft away from the second bevel gear is fixedly connected with a half-face gear. The motor is installed through the base. When the motor is started, the first bevel gear rotates under the action of the motor output shaft. Through the mutual meshing of the first bevel gear and the second bevel gear, the transmission shaft can be rotated, and then the half-face gear can be rotated. The provided support plate is used to support and rotate the transmission shaft to reduce the friction coefficient. The cleaning assembly includes a ring body.

A cleaning cotton is fixedly connected to the side of the housing facing away from the fixing plate. The cleaning cotton corresponds to and cooperates with the LED display screen. When the half-face gear rotates, through the mutual meshing of the half-face gear and the tooth teeth, and with the cooperation of the second guide plate and the second cavity plate, the ring body can move up and down reciprocally. Through the fixing plate, the housing can move up and down reciprocally, and then the cleaning cotton can move up and down reciprocally to clean the dust on the outer surface of the LED display screen when the display board moves, so as to improve the viewing effect. In actual use, the cleaning cotton needs to be replaced in time to avoid affecting the dust removal effect.
[0008] Preferably, a rectangular groove is provided through the side wall of the display board.

The piston at the bottom end of the lifting rod is located in the vertical cylinder and the piston at the bottom end of the lifting rod cooperates with the vertical cylinder. When the lifting board rises, the rectangular groove can prevent the transmission shaft from hindering the movement of the lifting board. When the lifting board rises, the transmission shaft moves downward relative to the lifting board. When the transmission shaft contacts the arc seat and generates a thrust on the arc seat, the lifting rod can move in the vertical cylinder. At this time, the spring is in a compressed state. The piston at the bottom end of the lifting rod can push the hydraulic oil in the vertical cylinder, so that the hydraulic oil can push the first movable rod and the second movable rod. The output end of the vertical cylinder is fixedly connected to a horizontal cylinder and a vertical cylinder. The end face of the horizontal cylinder is inserted and slidably connected to a first movable rod. The rod end of the first movable rod is fixedly connected to the side wall of the extension board.

One end of the wire rope is fixed to the piston at the lifting rod. The other end of the wire rope is respectively fixed to the pistons at the first movable rod and the second movable rod. When the piston at the bottom end of the lifting rod pushes the hydraulic oil in the vertical cylinder, the hydraulic oil can push the first movable rod and the second movable rod, so that the extension board extends out of the display board to increase the display surface, and the lifting board extends out of the boss to expose the placement groove. Quantum dot light-emitting diodes can be placed in the placement groove. By placing quantum dot light-emitting diodes in the placement grooves at different positions, different light-emitting patterns can be formed.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] 1. The present invention is provided with a driving component.

Through the meshing of the first bevel gear 206 and the second bevel gear 207, the transmission shaft 208 can be rotated, and then the half-face gear 210 can be rotated. The provided support plate 209 is used to support and rotate the transmission shaft 208 to reduce the friction coefficient.
[0030] The cleaning assembly 4 includes a ring body 401. A tooth 402 is fixedly connected to the inner side wall of the ring body 401. The half-face gear 210 is located within the ring opening of the ring body 401. The half-face gear 210 corresponds to and meshes with the tooth 402. A second guide plate 403 is fixedly connected to the outer side wall of the ring body 401. A second cavity plate 404 is fixedly connected to the inner side wall of the storage box 101. The second guide plate 403 corresponds to and is slidably connected to the second cavity plate 404. A fixing plate 405 is fixedly connected to the surface of the ring body 401 facing the display board 301.

Through the fixing plate 405, the housing 406 can be reciprocated up and down, and then the cleaning cotton 407 can be reciprocated up and down to clean the dust on the outer surface of the LED display screen 303 when the display board 301 moves, so as to improve the viewing effect. In actual use, the cleaning cotton 407 needs to be replaced in time to avoid affecting the dust removal effect.
[0032] A rectangular groove 302 is provided through the side wall of the display board 301. An extension board 304 is inserted and slidably connected to the upper part of the side wall of the display board 301. A lifting board 305 is provided on one side of the display board 301. The top surface of the lifting board 305 is fixedly connected to a top board 306. A placement groove 307 is provided through the side wall of the lifting board 305. The transmission shaft 208 passes through the rectangular groove 302, and the transmission shaft 208 can move up and down within the rectangular groove 302. A vertical cylinder 308 is fixedly connected to the inner bottom wall of the rectangular groove 302. A lifting rod 309 is inserted and slidably connected to the top surface of the vertical cylinder 308. A piston is fixedly connected to the bottom end of the lifting rod 309. An arc-shaped seat 310 is fixedly connected to the top end of the lifting rod 309. A spring 311 is provided around the side wall of the lifting rod 309. The top end of the spring 311 is fixedly connected to the bottom surface of the arc-shaped seat 310.

The piston at the bottom end of the lifting rod 309 is located within the vertical cylinder 308, and the piston at the bottom end of the lifting rod 309 cooperates with the vertical cylinder 308.
[0033] By adopting the above technical solution, when the lifting board 305 rises, the rectangular groove 302 can prevent the transmission shaft 208 from obstructing the movement of the lifting board 305. And when the lifting board 305 rises, the transmission shaft 208 moves downward relative to the lifting board 305. When the transmission shaft 208 contacts the arc-shaped seat 310 and generates a thrust on the arc-shaped seat 310, the lifting rod 309 can move within the vertical cylinder 308. At this time, the spring 311 is in a compressed state. The piston at the bottom end of the lifting rod 309 can push the hydraulic oil within the vertical cylinder 308, so as to push the first movable rod 313 and the second movable rod 315.
[0034] The output end of the vertical cylinder 308 is fixedly connected to a horizontal cylinder 312 and a vertical cylinder 314. A first movable rod 313 is inserted and slidably connected to the end face of the horizontal cylinder 312. The rod end of the first movable rod 313 is fixedly connected to the side wall of the extension board 304. A piston is fixedly connected to the end of the first movable rod 313 away from the extension board 304. The piston at the first movable rod 313 is located within the horizontal cylinder 312. A second movable rod 315 is inserted and slidably connected to the top surface of the vertical cylinder 314.

[0035] By adopting the above technical solution, a wire rope 316 is arranged inside the vertical cylinder 308, and one end of the wire rope 316 is fixed to the piston at the lifting rod 309, and the other end of the wire rope 316 is respectively fixed to the pistons at the first movable rod 313 and the second movable rod 315. When the piston at the bottom end of the lifting rod 309 pushes the hydraulic oil in the vertical cylinder 308, the first movable rod 313 and the second movable rod 315 can be pushed by the hydraulic oil, so that the expansion plate 304 extends out of the display board 301 to increase the display surface, and the lifting plate 305 can extend out of the boss 104 to expose the placement groove 307. Quantum dot light-emitting diodes can be placed in the placement groove 307. By placing quantum dot light-emitting diodes in the placement grooves 307 at different positions, different light-emitting patterns can be formed.
[0036] Working principle: When the present invention is in use and the display rack needs to be unfolded during a flash activity, the motor 201 is started. The worm 205 rotates under the action of the output shaft of the motor 201. Through the meshing of the worm 205 and the worm gear 211, the cross shaft 212 can be rotated, and then the transmission gear 213 can be rotated. Through the meshing of the transmission gear 213 and the toothed plate 214, and with the cooperation of the first guide plate 216 and the first cavity plate 217, the convex plate 215 can be lifted, and then the display board 301 can be lifted so that the display board 301 moves out of the storage box 101 for display.
[0037] When the motor 201 is started, the first bevel gear 206 rotates under the action of the output shaft of the motor 201. Through the meshing of the first bevel gear 206 and the second bevel gear 207, the transmission shaft 208 can be rotated, and then the half-face gear 210 can be rotated. Through the meshing of the half-face gear 210 and the teeth 402, and with the cooperation of the second guide plate 403 and the second cavity plate 404, the ring body 401 can move up and down reciprocally. The fixing plate 405 can make the housing 406 move up and down reciprocally, and then the cleaning cotton 407 can move up and down reciprocally to clean the outer surface of the LED display screen 303 when the display board 301 moves, so as to improve the viewing effect.
[0038] When the lifting plate 305 rises, the transmission shaft 208 moves downward relative to the lifting plate 305. When the transmission shaft 208 contacts the arc seat 310 and generates a thrust on the arc seat 310, the lifting rod 309 can move within the vertical cylinder 308. At this time, the spring 311 is in a compressed state. The piston at the bottom end of the lifting rod 309 can push the hydraulic fluid within the vertical cylinder 308, so that the hydraulic fluid can push the first movable rod 313 and the second movable rod 315, causing the expansion plate 304 to extend from the display board 301 to increase the display area, and the lifting plate 305 to extend from the boss 104 to expose the placement groove 307. Quantum dot light-emitting diodes can be placed in the placement groove 307. By placing quantum dot light-emitting diodes in different placement grooves 307, different light-emitting patterns can be formed;
[0039] After the display is completed, the motor 201 is controlled to lower the display board 301. At this time, the transmission shaft 208 moves away from the arc seat 310, and the spring 311 begins to return to its original state. Under the action of the elastic force of the spring 311 and with the cooperation of the wire rope 316, the expansion plate 304 and the lifting plate 305 can return to their original positions for storage, preventing the expansion plate 304 and the lifting plate 305 from obstructing the descent of the display board 301 when it falls.
