Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a flexible connection structure and a flexible LED display screen. Background Technology

[0002] In the display industry, flexible LED displays, with their unique bendable and foldable characteristics, are gradually becoming an important development direction for future display technology. A flexible LED display typically consists of a flexible module and multiple splicing cabinets installed on the back of the flexible module. During the splicing of a flexible LED display, the limited mobility between the splicing cabinets along the seam extension direction makes misalignment prone to occur, severely impacting the installation efficiency and display effect of the flexible LED display. Utility Model Content

[0003] The purpose of this application is to provide a flexible connection structure and a flexible LED display screen to solve the technical problem that the bottom shells of each cabinet of the flexible LED display screen are easily misaligned in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A flexible connection structure is provided, comprising:

[0006] Multiple box-shaped bottom shells are arranged sequentially along the unfolding direction of the flexible module, and each box-shaped bottom shell has a sequentially through mounting groove.

[0007] The flexible connector passes through each of the mounting slots and is connected to each of the box bottom shells, connecting each box bottom shell into a whole. This serves to restrict the movement of each box bottom shell along the length direction of the flexible connector, and also enables each box bottom shell to be aligned sequentially along the X-axis direction, preventing misalignment of each box bottom shell in the X-axis direction.

[0008] Multiple movable snap-fit ​​connectors are provided, each connected to a corresponding mounting slot, and the movable snap-fit ​​connectors are sequentially connected end-to-end along the unfolding direction of the flexible module. Each movable snap-fit ​​connector includes a slot at one end and / or a tenon at the other end. When the tenon is inserted into the slot on an adjacent movable snap-fit ​​connector, the corresponding two bottom shells of the housing are aligned and limited along the extension direction of their splice seam. Since the movable snap-fit ​​connectors traverse between the two bottom shells along the X-axis direction (perpendicular to the extension direction of the splice seam), the movable snap-fit ​​connectors are equivalent to guide pins traversing between the two bottom shells, enabling the two bottom shells to align with each other in the extension direction of the splice seam and preventing misalignment between the bottom shells.

[0009] As a further improvement to the above technical solution:

[0010] Optionally, the latch includes a round head and a neck. The round head is connected to one end of the neck, and the other end of the neck is connected to the body of the movable latching member. The width of the round head is greater than the width of the neck, and the round head is engaged in a slot on an adjacent movable latching member. The slot serves to lock and limit the round head, preventing it from dislodging from one side of the slot.

[0011] Optionally, one side of the slot has an opening that communicates with the outside, and the width of the opening is smaller than the width of the round head. When the round head is engaged in the slot on an adjacent movable engaging member, the round head cannot be dislodged outward through the opening, thus keeping the round head engaged and limited within the slot.

[0012] Optionally, the number of mounting slots on the bottom shell of the enclosure is multiple, and the mounting slots are arranged at intervals to make the structural stability between the bottom shells of the enclosure stronger and to avoid the connection stress being concentrated on a certain flexible connector and movable snap-fit.

[0013] Optionally, the flexible connector is provided with a plurality of first through holes, each first through hole corresponding to a mounting hole on each mounting groove, so as to install the flexible connector on the mounting groove.

[0014] Optionally, the movable snap-fit ​​connector is provided with a second through hole, the position of which corresponds to the position of the first through hole, so that the fastener can pass through the second through hole and the first through hole to connect the movable snap-fit ​​connector and the flexible connector to the mounting groove.

[0015] Optionally, it also includes a fastener that passes through the second through hole, the first through hole, and the mounting hole in sequence to secure the movable snap-fit ​​member and the flexible connector to the mounting groove and prevent the movable snap-fit ​​member and the flexible connector from loosening.

[0016] Optionally, the top surface of the box bottom shell is provided with at least two first magnetic attractors, and the bottom surface of the box bottom shell is provided with at least two second magnetic attractors. When the box bottom shell is connected to the box bottom shells adjacent to each other in the vertical direction, the first magnetic attractors and the second magnetic attractors are magnetically attracted and positioned. The mutual magnetic attraction of the first magnetic attractors and the second magnetic attractors achieves the initial positioning of the two box bottom shells.

[0017] Optionally, one of the top and bottom surfaces of the box shell is provided with a positioning protrusion, and the other of the top and bottom surfaces of the box shell is provided with a positioning groove. When the box shell is connected to an adjacent box shell in the vertical direction, the positioning protrusion extends into the positioning groove. When the box shell is connected to an adjacent box shell in the vertical direction, the positioning protrusion extends into the positioning groove, thereby achieving accurate positioning of the two box shells in the vertical direction and avoiding misalignment of the two box shells in the front-back direction.

[0018] This application also provides a flexible LED display screen, including a flexible module and the aforementioned flexible connection structure, wherein each housing bottom shell of the flexible connection structure is connected to the back side of the flexible module.

[0019] The beneficial effects of the flexible connection structure and flexible LED display provided in this application are as follows:

[0020] The flexible connection structure provided in this application includes flexible connectors, multiple box-shaped bottom shells, and movable snap-fit ​​connectors corresponding to the number of box-shaped bottom shells. The box-shaped bottom shells are arranged sequentially along a straight line, and each box-shaped bottom shell has a mounting groove that communicates with adjacent box-shaped bottom shells. The flexible connectors pass through each mounting groove and connect to each box-shaped bottom shell, linking them into a whole. This restricts the movement of each box-shaped bottom shell along the length of the flexible connector and also allows the box-shaped bottom shells to be aligned sequentially along the X-axis, preventing misalignment in the X-axis direction. The flexible connectors have a certain degree of flexibility, allowing each box-shaped bottom shell to bend forward / backward in an inward or outward arc shape, adapting to the bending degree of the flexible module. Each movable snap-fit ​​connector is connected to a corresponding mounting groove. Specifically, each movable snap-fit ​​connector includes a slot at one end, or a tenon at the other end, or a slot at one end and a tenon at the other end. When the movable snap-fit ​​components are sequentially connected end-to-end along the unfolding direction of the flexible module, and the snap-fit ​​tenons are inserted into the slots on adjacent movable snap-fit ​​components, the corresponding two bottom shells are aligned and limited along the extension direction of their joint. Since the movable snap-fit ​​components pass through the two bottom shells, they act as guide pins, ensuring vertical alignment and preventing misalignment. Furthermore, the limiting connection between the slots and snap-fit ​​tenons prevents easy separation between adjacent bottom shells, further enhancing the limiting effect.

[0042] In the following description, suffixes such as "circuit," "component," "assembly," or "unit" are used only for the purpose of describing this utility model and have no specific meaning in themselves. Therefore, they can be used in combination.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0044] To address the issue of misalignment between the base shells of various LED flexible display panels, such as... Figures 1 to 3 As shown, this application provides a flexible connection structure, specifically including a flexible connector 2, multiple box bottom shells 1, and movable snap-fit ​​connectors 3 corresponding to the number of box bottom shells 1.

[0045] The bottom shells 1 of each enclosure are arranged sequentially along a straight line and laid together on the back side of the flexible module 9. Each bottom shell 1 has a mounting groove 11 that communicates with the adjacent bottom shell 1.

[0046] The flexible connector 2 runs through each mounting slot 11 and connects to each box bottom shell 1, connecting each box bottom shell 1 into a whole. This restricts the movement of each box bottom shell 1 along the length direction of the flexible connector 2 (set as the X-axis direction), and also allows each box bottom shell 1 to be aligned sequentially along the X-axis direction, preventing misalignment of each box bottom shell 1 in the X-axis direction. The flexible connector 2 is specifically elongated. Due to its certain flexibility, each box bottom shell 1 can still bend in the forward / backward direction (set as the Y-axis direction) into an inward or outward arc shape, following the bending degree of the flexible module 9.

[0047] Based on this, each movable snap-fit ​​connector 3 is connected to its corresponding mounting slot 11. Specifically, each movable snap-fit ​​connector 3 includes a slot 31 at one end, or a tenon 32 at the other end, or a slot 31 at one end and a tenon 32 at the other end. When each movable snap-fit ​​connector 3 is sequentially connected end-to-end along the unfolding direction of the flexible module 9, the tenon 32 is inserted into the slot 31 on the adjacent movable snap-fit ​​connector 3, thus aligning the corresponding two bottom shells 1 along the extension direction of their joint (set as the Z-axis direction). Since the movable snap-fit ​​connector 3 traverses between the two bottom shells 1 along the X-axis direction, it acts as a guide pin traversing between the two bottom shells 1, enabling the two bottom shells 1 to align vertically and preventing misalignment in the Z-axis direction. Furthermore, due to the limiting connection between the slot 31 and the tenon 32, the two adjacent bottom shells 1 of the housing cannot be easily separated, thus further strengthening the limiting effect along the X-axis direction.

[0048] like Figure 2As shown, in one embodiment of this application, the latch 32 includes a round head 321 and a neck 322. The round head 321 is connected to one end of the neck 322, and the other end of the neck 322 is connected to the movable latching body 33. It should be noted that the width of the round head 321 is greater than the width of the neck 322. Therefore, when the round head 321 is latched into the slot 31 on the adjacent movable latching member 3, the slot 31 acts as a latching limit for the round head 321, preventing it from dislodging from one side of the slot 31.

[0049] like Figure 2 As shown, in one embodiment of this application, the slot 31 has an opening 311 on one side that communicates with the outside. It should be noted that the width of the opening 311 must be smaller than the width of the round head 321. When the round head 321 is engaged in the slot 31 on the adjacent movable latching member 3, the round head 321 cannot be dislodged outward through the opening 311, thereby keeping the round head 321 engaged and limited within the slot 31.

[0050] like Figures 1 to 3 As shown, in one embodiment of this application, there are multiple mounting slots 11 on the bottom shell 1 of the housing, and the mounting slots 11 are arranged at intervals. By setting multiple mounting slots 11, multiple interconnected mounting slots 11 are formed on each bottom shell 1 of the housing, and flexible connectors 2 and movable snap-fit ​​connectors 3 are installed in each interconnected mounting slot 11, which makes the structural stability between the bottom shells 1 of the housing stronger and avoids the connection stress from concentrating on a certain flexible connector 2 and movable snap-fit ​​connector 3.

[0051] like Figures 1 to 3 As shown, in one embodiment of this application, the flexible connector 2 is provided with a plurality of first through holes 21, each first through hole 21 corresponding to a mounting hole on each mounting groove 11, so as to install the flexible connector 2 on the mounting groove 11.

[0052] like Figures 1 to 3 As shown, in one embodiment of this application, the movable snap-fit ​​connector 3 is provided with a second through hole 34, the position of the second through hole 34 corresponding to the position of the first through hole 21, so that the fastener can pass through the second through hole 34 and the first through hole 21 to connect the movable snap-fit ​​connector 3 and the flexible connector 2 to the mounting groove 11.

[0053] In one embodiment of this application, the flexible connection structure further includes a fastener (not shown). The fastener passes sequentially through the second through hole 34, the first through hole 21, and the mounting hole to secure the movable snap-fit ​​member 3 and the flexible connector 2 to the mounting groove 11, preventing them from loosening. The fastener may specifically be a screw, bolt, or fastening pin, etc.

[0054] like Figure 4 As shown, in one embodiment of this application, the top surface of the box bottom shell 1 is provided with at least two first magnetic attractors 5, and the bottom surface of the box bottom shell 1 is provided with at least two second magnetic attractors 6. The top surface of the box bottom shell 1 refers to the end face located at the top when the box bottom shell 1 is in an upright state, and the bottom surface of the box bottom shell 1 refers to the end face located at the bottom when the box bottom shell 1 is in an upright state. When the box bottom shell 1 is connected to an adjacent box bottom shell 1 in the vertical direction, the mutual magnetic attraction of the first magnetic attractors 5 and the second magnetic attractors 6 achieves the initial positioning of the two box bottom shells 1. The magnetic pole orientations of the first magnetic attractors 5 on the top surface of the box bottom shell 1 can be the same or different, and the magnetic pole orientations of the second magnetic attractors 6 on the bottom surface of the box bottom shell 1 can be the same or different. However, it is necessary that the magnetic poles of the corresponding first magnetic attractors 5 and second magnetic attractors 6 be opposite to generate a magnetic attraction effect, rather than mutual repulsion.

[0055] like Figure 5 As shown, in one embodiment of this application, a positioning protrusion 7 is provided on the top surface of the bottom shell 1, and a positioning groove 8 is provided on the bottom surface of the bottom shell 1. Alternatively, a positioning groove 8 is provided on the top surface of the bottom shell 1, while a positioning protrusion 7 is provided on the bottom surface of the bottom shell 1. When the bottom shell 1 is connected to an adjacent bottom shell 1 in the vertical direction, the positioning protrusion 7 extends into the positioning groove 8, thereby achieving accurate positioning of the two bottom shells 1 in the vertical direction and avoiding misalignment of the two bottom shells 1 in the front-back direction / Y-axis direction.

[0056] like Figures 1 to 3 As shown, this application also provides a flexible LED display screen, including a flexible module 9 and the flexible connection structure in the above embodiments. Each cabinet bottom shell 1 of the flexible connection structure is connected to the back side of the flexible module 9 by means of fastener connection, insertion, snap-fit ​​connection, etc. The flexible connection structure enables the flexible connection of each cabinet bottom shell 1.

[0057] The flexible module 9, serving as the image display component of the flexible LED display screen, includes a flexible circuit board and LED chips. To adapt to different installation scenarios, the flexible module 9 can be bent. Since the aforementioned flexible LED display screen includes the flexible connection structure described in the above embodiments, it also possesses the advantages of the flexible connection structure described in the above embodiments.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
