Description

Technical Field

[0001] This invention relates to the field of display technology, and more specifically to a display screen with a flexible bending area. Background Technology

[0002] A display screen is an electronic device that converts electronic signals into images, text, or information that are visible to the naked eye.

[0003] Currently, the structure of the display screen is simple. When installed externally for display, it cannot provide a full-range display. In particular, when multiple displays are installed, they cannot be fitted to curved walls, affecting the display effect. Furthermore, they cannot provide double-sided or multi-angle displays as needed, further impacting the display quality. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a display screen with a flexible bending area, in which a main display screen and a secondary display screen are combined, and the secondary display screen can be adjusted at multiple angles to solve the problems mentioned in the background art.

[0005] This invention is achieved through the following technical solution: a display screen with a flexible bending area, comprising a main display screen and multiple sub-display screens. The main display screen has fixed posts installed at both ends in the width direction. One end of each sub-display screen is mounted on a fixed post, and the other end of each sub-display screen bends along the outer ring of the fixed post toward the back of the main display screen until they contact each other. The end of each sub-display screen away from the fixed post protrudes to form a positioning part. Multiple positioning grooves are provided on the opposite end face of the positioning part, and positioning plates are inserted into each positioning groove. Each fixed post has a channel opposite to the positioning groove, and the other end of each positioning plate extends into the channel. Each fixed post has an axially open mounting groove, and an adjustment mechanism for moving the positioning plate is installed in each mounting groove.

[0006] As a preferred technical solution, the adjustment mechanism includes a shaft, multiple gears, and multiple protruding teeth. The side of the positioning plate facing the main display screen has a horizontal groove, and the multiple protruding teeth are installed in the horizontal groove. The inner wall of the channel is provided with a rectangular opening that communicates with the mounting groove. The shaft is eccentrically set in the mounting groove, and the gear is installed on the shaft. A part of the gear extends to the outside along the rectangular opening and meshes with the protruding teeth. The end of the mounting groove away from the opening is embedded with a bearing. One end of the shaft is installed in the inner ring of the bearing, and the other end is installed with a positioning operation mechanism.

[0007] As a preferred technical solution, the positioning operation mechanism includes a limiting post, a grip rod, a pull ring and a compression spring. The grip rod is set in the opening of the mounting groove. The end face of the grip rod facing the shaft is eccentrically provided with a limiting groove. The limiting post is installed on the end of the shaft away from the bearing. The other end of each limiting post is inserted into the limiting groove and is fixedly connected to the compression spring. The other end of each compression spring is installed on the inner wall of the limiting groove. Each limiting post has a groove on the end face away from the shaft, and the pull ring is installed in the groove.

[0008] As a preferred technical solution, the outer end face of the grip bar is flush with the top surface of the main display screen, and the cross-sections of the limiting groove and the limiting post are both polygonal.

[0009] As a preferred technical solution, the positioning plate is provided with grooves on both sides, and sliders are installed on both sides of the channel, with the sliders slidably disposed in the grooves.

[0010] As a preferred technical solution, a mounting bracket is installed on the top surface of the main display screen, and the mounting bracket has multiple mounting holes.

[0011] As a preferred technical solution, the main display screen is an LED display screen, and the secondary display screen is a flexible screen.

[0012] As a preferred technical solution, the positioning plate is made of stainless steel.

[0013] As a preferred technical solution, the length of the fixing column is matched with the height of the main display screen and the secondary display screen.

[0014] The beneficial effects of this invention are as follows: The invention has a simple structure. Secondary displays are installed on both sides of the main display screen, and these secondary displays are flexible screens. When a double-sided display is required, the secondary displays on both sides can be bent towards the back of the main display screen and positioned by positioning plates inserted into positioning slots. After the positioning plates are removed from the positioning slots, the secondary displays can open outwards and be bent to any angle, allowing them to be adhered and fixed to a curved wall structure. When the secondary displays are directly opposite the main display screen, the positioning plates can extend outwards until they are reinserted into the positioning slots. The positioning plates provide support for the secondary displays, increasing the display range and functionality. The rotation of the positioning plates is achieved by a positioning operating mechanism. After the lever is pulled upwards from the mounting slot, it smoothly drives the rotation of the shaft. After the lever enters the mounting slot, it positions the shaft and the positioning plate to ensure effective positioning. Attached Figure Description

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a display screen with a flexible bending area includes a main display screen 1 and multiple sub-display screens 3. The main display screen 1 has fixed posts 2 installed at both ends in the width direction. One end of each sub-display screen 3 is installed on the fixed post 2, and the other end is bent along the outer ring of the fixed post 2 toward the back of the main display screen 1 until they are in contact with each other. The end of each sub-display screen 3 away from the fixed post 2 protrudes to form a positioning part 7. Multiple positioning grooves are provided on the opposite end face of the positioning part 7. Positioning plates 8 are inserted into each positioning groove. Each fixed post 2 has a channel 9 opposite to the positioning groove. The other end of each positioning plate 8 extends into the channel 9. Each fixed post 2 has an axially open mounting groove. An adjustment mechanism that drives the positioning plate 8 to move is installed in each mounting groove.

[0021] In this embodiment, the adjustment mechanism includes a shaft 13, multiple gears 11, and multiple protruding teeth 12. The positioning plate 8 has a horizontal groove on the side facing the main display screen 1. The multiple protruding teeth 12 are installed in the horizontal groove. The inner wall of the channel 9 is provided with a rectangular opening that communicates with the mounting groove. The shaft 13 is eccentrically set in the mounting groove. The gears 11 are installed on the shaft 13. A part of the gears 11 extends to the outside along the rectangular opening and meshes with the protruding teeth 12. The end of the mounting groove away from the opening is embedded with a bearing. One end of the shaft 13 is installed in the inner ring of the bearing, and the other end is installed with a positioning operation mechanism.

[0022] In this embodiment, the positioning operation mechanism includes a limiting post 15, a gripping rod 5, a pull ring 6 and a compression spring. The gripping rod 5 is set in the opening of the mounting groove. The end face of the gripping rod 5 facing the shaft 13 is eccentrically provided with a limiting groove. The limiting post 15 is installed on the end of the shaft 13 away from the bearing. The other end of each limiting post 15 is inserted into the limiting groove and is fixedly connected to the compression spring. The other end of each compression spring is installed on the inner wall of the limiting groove. Each limiting post 15 has a groove on the end face away from the shaft 13, and the pull ring 6 is installed in the groove.

[0023] In this embodiment, the outer end face of the grip 5 is flush with the top surface of the main display screen 1, and the cross-sections of the limiting groove and the limiting post 15 are both polygonal. Because the shaft and the limiting groove are eccentrically set, the shaft can be limited after the limiting post is inserted into the opening of the positioning groove, so that the shaft cannot rotate on its own, thereby achieving the effect of locking the shaft and the gear, and simultaneously completing the positioning of the positioning plate.

[0024] In this embodiment, the positioning plate 8 is provided with sliding grooves 14 on both sides, and the channel 9 is provided with sliders 10 on both sides. The sliders 10 are slidably disposed in the sliding grooves 14, so that the positioning plate can only move back and forth with the sliders, thus preventing the positioning plate from directly detaching from the channel.

[0025] In this embodiment, a mounting bracket 4 is installed on the top surface of the main display screen 1. The mounting bracket 4 has multiple mounting holes, and bolts can pass through the mounting holes to install the mounting bracket on the wall.

[0026] In this embodiment, the main display screen 1 is an LED display screen, and the secondary display screen 3 is a flexible screen.

[0027] In this embodiment, the positioning plate 8 is made of stainless steel, which increases its sturdiness and load-bearing capacity.

[0028] In this embodiment, the length of the fixing column 2 is matched with the height of the main display screen 1 and the secondary display screen 3, so that the heights are the same, thus ensuring display quality.

[0029] Working principle: The main display screen 1 has fixed posts 2 at both ends in the width direction. One end of each of the two secondary display screens 3 is installed on the corresponding fixed posts 2, and the other end can be bent along the outer ring of the fixed posts 2 toward the back of the main display screen 1 until the two secondary display screens 3 touch each other. This state is the double-sided display state of the display screen.

[0030] At this time, the end of the secondary display screen 3 away from the fixed post 2 protrudes to form a positioning part 7. Multiple positioning grooves are provided on the opposite end face of the positioning part 7. One end of the positioning plate 8 is inserted into the positioning groove, and the other end extends into the interior of the fixed post 2 through the channel 9. The positioning plate 8 is guided in the channel 9 by the slider 10 and the sliding groove 14 to maintain the stability of horizontal movement. The insertion state of the positioning plate 8 locks the secondary display screen 3 in the storage position to prevent it from being accidentally unfolded.

[0031] The adjustment mechanism is installed in the mounting slot axially opened in the fixed column 2, and its core transmission path is as follows: The shaft 13 is eccentrically positioned in the mounting groove. One end of the shaft is mounted in the bearing to achieve rotational support, and the other end is connected to the handle 5 through the positioning operating mechanism. A gear 11 is fixedly mounted on the shaft 13, and a part of the gear 11 extends into the channel 9 through the rectangular opening in the inner wall of the mounting groove.

[0032] The positioning plate 8 has a horizontal groove on the side facing the main display screen 1. Multiple protruding teeth 12 are installed in the horizontal groove. The protruding teeth 12 are engaged with the gear 11. When the shaft 13 rotates, the gear 11 drives the protruding teeth 12 to move in a straight line, thereby driving the positioning plate 8 to extend or retract horizontally in the channel 9 along the direction of the slider 10, which can ensure that the positioning plate 8 is accurately inserted into or removed from the positioning groove.

[0033] The positioning mechanism is installed at the open end of the mounting slot, and its specific working process is as follows: unlocking and pulling out: The operator pulls the lever 5 upwards using the pull ring 6. The lever 5 overcomes the spring force of the compression spring and moves outwards until it reaches the outside, but does not disengage from the limiting post. The outward-moving lever can drive the rotation of the limiting post and the shaft. Since the cross-section of the limiting groove and the limiting post 15 are both polygonal, the effective transmission of torque is ensured. The rotation of the shaft 13 drives the gear 11 to rotate. The gear 11 drives the positioning plate 8 to move horizontally along the channel 9 through meshing with the convex tooth 12. Depending on the direction of rotation, the positioning plate 8 can move away from or towards the positioning groove.

[0034] Locking and Resetting: Once the positioning plate 8 is completely removed from the positioning slot, the secondary display screen 3 is unlocked and can be freely bent to any angle along the fixing post 2, allowing the secondary display screen to be adhered and fixed to the curved wall structure, increasing the adaptability of the installation.

[0035] The secondary display screen 3 is a flexible screen. After the positioning plate 8 exits the positioning groove, it can achieve the following multiple working modes along the outer ring of the fixing column 2: Single-sided extended display mode: The secondary display screen 3 is opened outwards to be on the same plane as the main display screen 1 or at a certain angle, and the positioning plate is inserted into the positioning slot again through the outward-extending positioning plate. At this time, the display range is expanded, which is suitable for conventional large screen display scenarios.

[0036] Dual-sided display mode: The two secondary display screens 3 are bent to the back of the main display screen 1 and made in contact with each other, and locked by the positioning plate 8. At this time, the front of the main display screen 1 and the back of the secondary display screen 3 face different directions at the same time, realizing dual-sided display.

[0037] Curved Adhesion Display Mode: The secondary display screen 3 can be bent to the corresponding angle according to the curvature of the curved wall or irregular installation surface, and then adhered and fixed. This mode solves the technical problem that traditional display screens cannot adhere to curved walls.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
