Description

Technical Field

[0001] This utility model relates to the field of display screens, specifically a flexible liquid crystal display screen with adjustable screen. Background Technology

[0002] Flexible display technology is one of the major breakthroughs in the technology industry in recent years. It enables the screens of electronic devices to be bent and folded, breaking the inherent form limitations of traditional displays. This not only provides consumers with a brand-new user experience, but also brings revolutionary changes to the field of display technology.

[0003] With the continuous development of urban construction, flexible displays are increasingly being used as a new advertising medium. Since different application scenarios may require different display areas, existing flexible displays use motors to drive rotating rollers to roll up the flexible display, making it easy to adjust the display size.

[0004] Existing flexible displays typically descend vertically under their own weight after being rolled up. However, these displays need to be moved frequently to different locations for use, which can cause shaking during movement, potentially leading to tearing or damage to the screen and reducing its lifespan. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a flexible liquid crystal display screen with adjustable screen to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexible liquid crystal display screen with adjustable screen, including a mounting plate, on which a flexible liquid crystal display screen body is mounted. The flexible liquid crystal display screen body has a sliding component that cooperates with the mounting plate. A mounting box is provided on the mounting plate. A winding mechanism for driving the flexible liquid crystal display screen body to wind up is installed inside the mounting box. A horizontal pull plate is provided at the bottom of the flexible liquid crystal display screen body. A fixing component for fixing the wound flexible liquid crystal display screen body is provided inside the mounting box. The fixing component includes a fixing block on the horizontal pull plate, and a protrusion is provided on the fixing block. A slot communicating with the interior is opened at the bottom of the mounting box, and the protrusion matches the slot. A driving block 404 is provided inside the mounting box 101, and the driving block 404 is located on both sides of the protrusion 401. A limiting block 405 is provided on one side of the driving block 404. A driving mechanism for moving the driving block 404 and abutting against the protrusion 401 is provided inside the mounting box 101, and the driving mechanism is connected to the winding mechanism via a transmission component.

[0007] By adopting the above technical solution, the drive motor is started to drive the rotating roller to rotate, thereby winding the flexible liquid crystal display body. When the rotating roller rotates, it drives the belt to operate and at the same time drives the screw to rotate to complete the transmission, thereby driving the two drive blocks to move relative to each other. By setting the second slide groove and the second slider, the drive blocks can only move horizontally. When the flexible liquid crystal display body is wound up to the point where the horizontal pull plate is in contact with the bottom of the mounting box, the limiting block set at the end of the drive block abuts against the protrusion to complete the fixation.

[0008] The present invention is further configured such that the sliding member includes a first slider symmetrically disposed at the rear end of the flexible liquid crystal display body, and the mounting plate is provided with a first groove that cooperates with the first slider.

[0009] Preferably, since the flexible liquid crystal display body is relatively light, it may sway during movement. The cooperation of the first slider and the first groove ensures that the flexible liquid crystal display body remains horizontal during up and down movement.

[0010] The present invention is further configured such that the winding mechanism includes a rotating roller rotatably disposed in the mounting box, one end of the rotating roller being connected to the output end of a drive motor, the flexible liquid crystal display body being sleeved on the outer surface of the rotating roller, and the bottom of the mounting box having a slot that mates with the flexible liquid crystal display body.

[0011] Preferably, the drive motor is started to drive the rotating roller to rotate, thereby winding the flexible liquid crystal display body. The flexible liquid crystal display body moves upward in the slot until the horizontal pull plate is in contact with the bottom of the mounting box, and the fixing component installed on one side of the horizontal pull plate is fixed.

[0012] The present invention is further provided that a mounting frame is provided on one side of the mounting box, and the mounting frame is used to mount the drive motor.

[0013] Preferably, the mounting frame can ensure the stability of the drive motor during operation and prevent movement or tilting caused by vibration or external force, thereby ensuring the stable operation of the drive motor.

[0014] The present invention is further configured such that the driving mechanism includes a screw rotatably disposed in the mounting box, and the screw 403 has opposite threads on its surface, the driving block is threadedly sleeved on the outer surface of the screw, and the bottom of the driving block is provided with a limiting member that cooperates with the mounting box.

[0015] Preferably, while the rotating roller is winding the flexible liquid crystal display body, the screw is driven to rotate through the transmission component, thereby driving the drive block to move.

[0016] The present invention is further configured such that the limiting member includes a second slider disposed at the bottom of the driving block, and a second groove that cooperates with the second slider is provided at the bottom of the inner wall of the mounting box.

[0017] Preferably, since the drive block rotates with the screw when the screw rotates, the second slide groove and the second slider are provided so that the drive block can only move horizontally.

[0018] The present invention is further configured such that the transmission component is a belt, the screw is connected to the rotating roller via the belt, and both the rotating roller and the outer surface of the screw are provided with pulleys.

[0019] Preferably, when the rotating roller rotates, it drives the belt to operate, and at the same time drives the screw to rotate to complete the transmission.

[0020] The present invention is further configured such that the two ends of the protrusion that contact the limiting block are serrated.

[0021] Preferably, the two sides of the protrusion that contact the limiting block are serrated, and the serrated design can increase the friction when in contact with the groove.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model uses a fixing component to facilitate the fixing of the flexible liquid crystal display body after winding. When the rotating roller rotates, it drives the belt to operate and simultaneously drives the screw to rotate to complete the transmission, thereby driving the two driving blocks to move relative to each other. By setting a second sliding groove and a second slider, the driving blocks can only move horizontally. When the flexible liquid crystal display body is wound up to the point where the horizontal pull plate is in contact with the bottom of the mounting box, the limiting block set at the end of the driving block abuts against the protrusion to complete the fixing.

[0024] 2. This utility model facilitates the horizontal movement of the flexible liquid crystal display body by setting a sliding member. When the winding mechanism drives the flexible liquid crystal display body to wind up, the flexible liquid crystal display body may shake during the movement because it is relatively light. The cooperation of the first slider and the first groove ensures that the flexible liquid crystal display body remains horizontal during the up and down movement. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Please see Figures 1-7The system includes a mounting plate 100 on which a flexible liquid crystal display screen body 102 is mounted. The flexible liquid crystal display screen body 102 has a sliding component that cooperates with the mounting plate 100. A mounting box 101 is provided on the mounting plate 100. A winding mechanism for winding the flexible liquid crystal display screen body 102 is installed inside the mounting box 101. A horizontal pull plate 103 is provided at the bottom of the flexible liquid crystal display screen body 102. A fixing component for fixing the wound flexible liquid crystal display screen body 102 is provided inside the mounting box 101. The fixing component includes a fixing block 400 mounted on the horizontal pull plate 103. The fixing block 400 is provided with a protrusion 401, and the bottom of the mounting box 101 is provided with a slot 402 communicating with the interior, and the protrusion 401 matches the slot 402. The mounting box 101 is provided with a driving block 404, and the driving block 404 is located on both sides of the protrusion 401. A limiting block 405 is provided on one side of the driving block 404. The mounting box 101 is provided with a driving mechanism that drives the driving block 404 to move and abuts against the protrusion 401, and the driving mechanism is connected to the winding mechanism through a transmission component. The two surfaces of the protrusion 401 that contact the limiting block 405 are serrated. The serrated design can increase the friction when in contact with the slide groove.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-4 The sliding member includes a first slider 301 symmetrically arranged at the rear end of the flexible liquid crystal display body 102, and a first groove 300 that cooperates with the first slider 301 is provided on the mounting plate 100.

[0038] When the winding mechanism drives the flexible liquid crystal display body 102 to wind up, the flexible liquid crystal display body 102 is relatively light and may shake during the movement. The cooperation of the first slider 301 and the first slide groove 300 keeps the flexible liquid crystal display body 102 horizontal during the up and down movement.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The winding mechanism includes a rotating roller 201 rotatably disposed in the mounting box 101. One end of the rotating roller 201 is connected to the output end of the drive motor 200. The flexible liquid crystal display body 102 is sleeved on the outer surface of the rotating roller 201. The bottom of the mounting box 101 is provided with a slot 203 that cooperates with the flexible liquid crystal display body 102.

[0040] The drive motor 200 is started to drive the rotating roller 201 to rotate, thereby winding up the flexible liquid crystal display body 102. The flexible liquid crystal display body 102 moves upward in the slot 203 until the horizontal pull plate 103 is attached to the bottom of the mounting box 101, and the fixing component installed on one side of the horizontal pull plate 103 is fixed.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The mounting box 101 has a mounting frame 202 on one side, which is used to mount the drive motor 200.

[0042] The mounting frame 202 facilitates the fixing of the drive motor 200. The mounting frame 202 can ensure the stability of the drive motor 200 during operation and prevent movement or tilting caused by vibration or external force, thereby ensuring the stable operation of the drive motor 200.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The driving mechanism includes a screw 403 rotatably disposed in the mounting box 101, and the screw 403 has opposite threads on its surface. The driving block 404 is threadedly sleeved on the outer surface of the screw 403, and the bottom of the driving block 404 is provided with a limiting member that cooperates with the mounting box 101.

[0044] As the rotating roller 201 rotates to wind up the flexible liquid crystal display body 102, the screw 403 is driven to rotate through the transmission component, thereby driving the two driving blocks 404 to move relative to each other. Due to the setting of the limiting component, the driving block 404 can only move horizontally. When the flexible liquid crystal display body 102 is wound up to the point where the horizontal pull plate 103 is in contact with the bottom of the mounting box 101, the limiting block 405 set at the end of the driving block 404 abuts against the protrusion 401 to complete the fixation.

[0045] For details regarding the above embodiments, please refer to [link / reference]. Figures 6-7 The limiting component includes a second slider 501 disposed at the bottom of the driving block 404, and a second groove 500 that cooperates with the second slider 501 is provided at the bottom of the inner wall of the mounting box 101.

[0046] Since the drive block 404 rotates with the screw 403 when the screw 403 rotates, the second slide 500 and the second slider 501 are set so that the drive block 404 can only move horizontally.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The transmission component is a belt 406, and the screw 403 is connected to the rotating roller 201 via the belt 406. Both the rotating roller 201 and the screw 403 are provided with pulleys on their outer surfaces.

[0048] Both the rotating roller 201 and the screw 403 are fitted with pulleys on their outer surfaces. The belt 406 is fitted on the two pulleys. When the rotating roller 201 rotates, it drives the belt 406 to operate, and at the same time drives the screw 403 to rotate to complete the transmission. At the same time, the winding mechanism drives the drive block 404 to drive the winding mechanism. When the flexible liquid crystal display body 102 is wound up to the point where the horizontal pull plate 103 is in contact with the bottom of the mounting box 101, the two limit blocks 405 abut against the protrusion 401 to complete the fixation.

[0049] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The two ends of the protrusion 401 that contact the limiting block 405 are serrated.

[0050] The two sides of the protrusion 401 that contact the limiting block 405 are serrated. The serrated design can increase the friction when in contact with the groove.

[0051] In practical operation, the following steps are taken: The drive motor 200 is started to rotate the rotating roller 201, thereby winding the flexible liquid crystal display body 102. The flexible liquid crystal display body 102 moves upward within the slot 203. Due to its light weight, the flexible liquid crystal display body 102 may sway during movement. The cooperation of the first slider 301 and the first groove 300 ensures that the flexible liquid crystal display body 102 remains horizontal during vertical movement. Both the rotating roller 201 and the screw 403 have pulleys on their outer surfaces. A belt 406 is fitted onto the two pulleys. When the rotating roller 201 rotates, it drives the belt 406 to operate, simultaneously driving the screw 403 to rotate and complete the transmission, thereby driving the two drive blocks 404 to move relative to each other. By setting the second groove 500 and the second slider 501, the drive blocks 404 can only move horizontally. When the flexible liquid crystal display body 102 is wound up to the point where the horizontal pull plate 103 is in contact with the bottom of the mounting box 101, the limiting block 405 at the end of the drive block 404 abuts against the protrusion 401, completing the fixation.
