A display screen alignment structure and an LED display screen

Abstract

This invention provides a display screen alignment structure and an LED display screen. The alignment structure includes a base, a slider, and an alignment member. The base is connected to one of two adjacent display units and has an alignment through hole and a mounting cavity. The slider is housed in the mounting cavity and can move relative to the mounting cavity. The alignment member is installed in the alignment through hole and can move relative to the base, allowing the alignment end of the alignment member to extend out of the alignment through hole and into the positioning hole of the other display unit, thereby aligning the two display units. Simultaneously, the slider has a guide slope, and the connecting end of the alignment member can fit against the guide slope. When the slider moves relative to the base, the connecting end moves along the guide slope, causing the alignment end to extend or retract into the alignment through hole, thereby locking or unlocking the alignment and facilitating the splicing or disassembly of the display units.

Description

Technical Field

[0001] This invention relates to the field of splicing display technology, and in particular to a display alignment structure and an LED display. Background Technology

[0002] LED displays can be composed of several display units spliced ​​together. Due to the limitations of manufacturing precision, during the splicing process, step differences can easily form between different display units, thereby reducing the display quality of the LED display and providing users with a poor visual experience.

[0003] To address the segment differences that arise when splicing individual display units, existing LED displays typically incorporate positioning or alignment structures on the display units to minimize these differences during splicing.

[0004] However, the existing positioning and alignment structures can easily affect the splicing efficiency of the display units, thereby affecting the assembly or disassembly of the display units, which is not conducive to the use and maintenance of LED displays. Summary of the Invention

[0005] The purpose of this invention is to provide a display screen alignment structure that facilitates the alignment of display units and the assembly or disassembly of display units.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a display screen alignment structure is provided for connection to a display unit to align two adjacent display units.

[0008] In one embodiment of this application, a guide ramp is provided on the connecting end; the guide ramp matches the guiding ramp so that the guide ramp can abut against the guiding ramp and move relative to the guiding ramp.

[0009] In one embodiment of this application, the display alignment structure further includes a connector; the connector is connected between the slider and the alignment member to fit the guide ramp onto the guide ramp.

[0011] In one embodiment of this application, the display screen alignment structure further includes a limiting member; the limiting member is disposed at the axial end of the slider and can be limited on the inner wall of the mounting cavity to restrict the movement of the slider relative to the base.

[0012] In one embodiment of this application, the display screen alignment structure further includes an adsorption member; the adsorption member is fixed in the mounting cavity and located on the side facing the limiting member, so that the adsorption member can adsorb the limiting member and restrict the movement of the sliding member relative to the base.

[0013] In one embodiment of this application, the limiting member is a magnetic member, and the adsorption member is a metal member that can be magnetically adsorbed with the magnetic member, so that the magnetic member can be magnetically adsorbed onto the metal member.

[0014] In one embodiment of this application, two of each of the limiting members and the adsorption members are provided. The two limiting members are respectively provided at both ends of the sliding member along the axial direction, and the two adsorption members are installed on opposite sides of the mounting cavity and are respectively provided corresponding to the limiting members, so that when the sliding member moves along the axial direction, the limiting members can move towards the adsorption members and be magnetically adsorbed onto the adsorption members.

Detailed Implementation

[0030] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0031] In the description of this invention, it should be understood that, in the embodiments shown in the drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In the LED display technology field, the conventional design solution for addressing height differences in the mid-to-high-end market is as follows: A matching cabinet is designed, with the cabinet itself achieving a high degree of flatness through CNC machining. Simultaneously, the cabinet incorporates vertical or horizontal connecting structures (such as positioning posts and holes) to ensure proper height differences during splicing between cabinets. Furthermore, the display units are mounted to the cabinet using screws or magnets, and the height difference between the display units and the cabinet is adjusted by changing the screw or magnet connection position, thereby minimizing height differences during splicing. However, this method of preventing height differences is costly and can easily affect the splicing efficiency of the display units.

[0034] In the low-to-mid-range market, there exists a type of display unit without a cabinet design or a non-load-bearing display unit. Specifically, the display unit is equipped with magnets that attach to a steel structure. The splicing step difference is adjusted by changing the height or thickness of the magnets on the display unit. However, due to the bulkiness of the steel structure and cost constraints, it is usually only vertically arranged, which easily leads to step difference issues at the horizontal splicing points of the display units. Furthermore, most applications of this design lack rear maintenance space, requiring front installation and maintenance. Additionally, due to the need to balance the disassembly and maintainability of the display unit, it is impossible to design a simple positioning post to solve the problem of splicing step difference in the display units based on the above solutions.

[0035] Therefore, existing positioning and alignment structures can easily affect the splicing efficiency of display units, thus impacting their assembly or disassembly, which is detrimental to the use and maintenance of LED displays. Therefore, to address the issue of preventing step-drop problems in cabinet-less or non-load-bearing display units, and to accommodate front maintenance and installation, a new display alignment structure is proposed to solve the aforementioned problems.

[0036] The solution is further illustrated by the following examples:

[0037] Figure 1 This is a schematic diagram of an LED display screen according to an embodiment of the present invention. Figure 2 This is a schematic cross-sectional view of the display screen alignment structure according to an embodiment of the present invention.

[0038] Please see Figure 1 and Figure 2 The LED display screen of this embodiment may include multiple display units 1 and a display screen alignment structure. Specifically, the multiple display units 1 can be spliced ​​together to form a complete LED display screen.

[0039] In this embodiment, the display unit 1 may include a display module 102 and a mounting frame 103, with the display module 102 fixed to the mounting frame 103. The display unit 1 has positioning holes 101, and a display alignment structure is disposed on the display unit 1; that is, the mounting frame 103 has positioning holes 101, and the display alignment structure is disposed on the mounting frame 103. The display module 102 may be an LED module or other display elements. The mounting frame 103 may be a metal frame or a plastic frame for mounting the display module 102.

[0040] Therefore, when multiple display units 1 are spliced ​​together, the alignment member 30 of the display alignment structure on one of the two adjacent display units 1 can extend into the positioning hole 101 on the other display unit 1, thereby aligning the two adjacent display units 1 to prevent the two adjacent display units 1 from having a height difference (i.e., a step difference), ensuring the flatness between the two display units 1, so as not to bring bad visual effects to the user.

[0041] It should be noted that each side of the display unit 1 can be provided with a display screen alignment structure, so that each side of the display unit 1 can be connected to other display units 1 to splice them into a whole display screen.

[0042] In practical use, LED displays can be spliced ​​together by multiple display units 1 in a nine-square grid, or in a rectangular or strip shape, to meet the actual needs of users.

[0043] Of course, in some other embodiments, each side of the display unit 1 may be provided with a display screen alignment structure, and each side of the display unit 1 may be provided with a positioning hole 101. At the same time, the display screen alignment structure and the positioning hole 101 are correspondingly arranged. In the splicing of multiple display units 1, each side of adjacent display units 1 can be aligned by at least two display screen alignment structures, thereby avoiding step difference between two adjacent display units 1.

[0044] See Figure 1 and Figure 2 The display screen alignment structure of this embodiment may include a base 10, a slider 20, and an alignment member 30.

[0045] The base 10 can be connected to the display unit 1, or the base 10 can also be formed on the display unit 1. That is, the base 10 can be connected to the mounting frame 103 of the display unit 1 by means of welding or screw connection, or the base 10 can also be directly formed on the mounting frame 103.

[0046] In this embodiment, the base 10 may be provided with an alignment through hole 11 and a mounting cavity 12. The alignment through hole 11 communicates with the mounting cavity 12, and the axis of the alignment through hole 11 is arranged at an angle to the axis of the mounting cavity 12. Specifically, the axis of the alignment through hole 11 is perpendicular to the central axis of the mounting cavity 12.

[0047] Of course, in some other embodiments, the axis of the alignment through hole 11 and the central axis of the mounting cavity 12 can also be set at other angles, such as 45° angle, 60° angle, etc.

[0048] The slider 20 can be housed within the mounting cavity 12 and is movable relative to the base 10. Specifically, the slider 20 can move along the axis of the mounting cavity 12, allowing it to reciprocate along the axial direction of the mounting cavity 12. Of course, in some other embodiments, the slider 20 can also rotate about the axis of the mounting cavity 12.

[0049] Alignment member 30 can be disposed within alignment through hole 11, and connection end 31 and alignment end 32 are respectively provided at both ends of alignment member 30 in the axial direction. The alignment member 30 can move relative to base 10, so that alignment end 32 can extend out of alignment through hole 11 and into positioning hole 101 on another display unit 1, thereby aligning the two adjacent display units 1 and avoiding step difference between the two adjacent display units 1.

[0050] See Figure 2 The slider 20 may be provided with a guide slope 21, and the connecting end 31 of the alignment member 30 is attached to or abutted against the guide slope 21 and can move relative to the slider 20.

[0051] In this embodiment, the guide slope 21 is inclined in the axial direction of the slider 20 from its central axis toward a direction away from the axis, so that when the slider 20 moves axially, the alignment member 30 can move relative to the slider 20 along the guide slope 21.

[0052] Of course, in some other embodiments, the guide slope 21 is inclined in the radial direction of the slider 20 away from its central axis, so that when the slider 20 rotates about the axis of the mounting cavity 12, the alignment member 30 can move relative to the slider 20 along the guide slope 21. It should be noted that in this embodiment, the guide slope 21 is an arc-shaped surface, so that when the slider 20 rotates, the connecting end 31 abuts against the guide slope 21, so that the slider 20 can rotate smoothly and drive the alignment member 30 to move away from or closer to the central axis of the slider 20.

[0053] Therefore, when the slider 20 moves relative to the base 10, the connecting end 31 can move along the guide slope 21 to drive the alignment end 32 of the alignment member 30 to extend out of or retract into the alignment through hole 11. For example, when the slider 20 moves relative to the base 10 in a certain direction along the axial direction of the mounting cavity 12, the slider 20 can drive the alignment member 30 to move through the guide slope 21, causing the alignment end 32 to extend out of the alignment through hole 11 and into the positioning hole 101, so as to realize the splicing and alignment of two adjacent display units 1 and avoid the step difference between the two display units 1. When the slider 20 moves relative to the base 10 in the opposite direction, the slider 20 can drive the alignment member 30 to disengage from the positioning hole 101 and retract into the alignment through hole 11 through the guide slope 21, thereby facilitating the disassembly of the two display units 1.

[0054] Figure 3 yes Figure 2 A schematic diagram of the alignment structure of the display screen.

[0055] See Figure 2 and Figure 3 A guide slope 311 may be provided on the connecting end 31. The inclination direction of the guide slope 311 is the same as that of the guide slope 21, allowing the guide slope 311 to fit against the guide slope 21 and move relative to it. It should be noted that the guide slope 311's contact area with the guide slope 21 increases the contact area between them and improves the stability of the connection between the sliding member 20 and the aligning member 30, preventing wobbling of the aligning member 30 when it moves relative to the sliding member 20.

[0056] Figure 4 yes Figure 2 A schematic diagram of the sliding component and the alignment component of the display screen alignment structure. Figure 5 yes Figure 2 Another schematic diagram of the sliding component and the alignment component of the display screen alignment structure. Figure 6 yes Figure 2 A schematic diagram of the sliding component of the display screen alignment structure. Figure 7 yes Figure 2 Another schematic diagram of the sliding component of the display screen alignment structure.

[0057] See Figure 2 , Figure 4 and Figure 5 The display alignment structure may also include a connector 40.

[0058] The connector 40 connects the slider 20 and the aligning member 30 to fit or restrict the guide slope 311 onto the guide slope 21, allowing the aligning member 30 to move with the slider 20. Specifically, the connector 40 fits or restricts the guide slope 311 onto the guide slope 21, ensuring that the guide slope 311 remains fitted or connected to the aligning end 31 while the slider 20 moves. Furthermore, the aligning member 30 can move relative to the slider 20 while the slider 20 moves, allowing the aligning end 32 to extend or retract from the aligning through hole 11.

[0059] Meanwhile, a guide portion 22 may be provided on the slider 20, and a guide slope 21 is formed on the guide portion 22.

[0060] In this embodiment, the guide portion 22 can be configured as a plate-like structure with a certain thickness. The connector 40 can be connected to the guide portion 22 and can move along the guide portion 22, thereby limiting or abutting the guide ramp 311 against the guide ramp 21 during the movement of the alignment member 30 relative to the sliding member 20. Specifically, the guide portion 22 can be configured as a guide rail structure, so that one end of the connector 40 can be connected to the guide portion 22 and can slide along the guide portion 22.

[0061] See Figure 6 and Figure 7 In this embodiment, the slider 20 may further include a connecting portion 25 and two shaft ends 26. One end of the connecting portion 25 is connected to one end of the guide portion 22, and the other end is connected to the shaft end 26. Simultaneously, the guide portion 22 is connected to the other shaft end 26 on one side relative to the connecting portion 25. Furthermore, the radial cross-section of the connecting portion 25 is smaller than the radial cross-section of the shaft end 26, and the connecting portion 25 is connected to the sidewall of the shaft end 26, causing the connecting portion 25 to deviate from the central axis of the shaft end 26. This creates a clearance space 27 between the shaft end 26 and the guide portion 22, specifically, a clearance space 27 is formed between the side of the guide portion 22 facing away from the guide slope 21 and the shaft end 26, allowing the alignment member 30 to move relative to the slider 20 within the movement space 28. Specifically, the slider 20 has a generally "Z" shaped structure.

[0062] It should be noted that a limiting part 29 may also be provided on the sliding member 20. The limiting part 29 is a straight cutting plane, which allows the limiting part 29 to abut against the abutting structure of the mounting cavity 12 to restrict the sliding member 20 from rotating around its own axis, so that the sliding member 20 can only move relative to the base 10 along its own axis.

[0063] Figure 8 yes Figure 2A schematic diagram of the connectors for the alignment structure of the display screen.

[0064] See Figure 4 , Figure 6 and Figure 8 The guide section 22 may have a through guide groove 23 so that the connector 40 can pass through the guide groove 23. At the same time, one end of the connector 40 is fixedly connected to the connecting end 31, and the end of the connector 40 away from the connecting end 31 is provided with a top abutment 41. The top abutment 41 can abut against the side of the guide section 22 away from the guide slope 21 so as to fit the guide slope 311 against the guide slope 21.

[0065] In this embodiment, the connector 40 can be configured as a stepped screw, and the stepped screw includes a nut, a stepped portion 42, and a threaded portion 43. The nut serves as the abutment 41, the stepped portion 42 passes through the guide groove 23 to allow the stepped screw to move along the guide groove 23, and the threaded portion 43 is used to connect to the connecting end 31, allowing the stepped screw to be fastened together with the aligning member 30, and to fit or limit the aligning member 30 against the guide slope 21.

[0066] In some other embodiments, the connector 40 may be configured as a snap-fit ​​member, and the abutment 41 may be configured as a snap-fit ​​claw of the snap-fit ​​member, so that the abutment 41 can engage with both sides of the guide portion 22 in the radial direction, thereby fitting or limiting the alignment member 30 to the guide slope 21.

[0067] It should be noted that, such as Figure 2 As shown, the base 10 has mounting holes to facilitate the installation of the connector 40. That is, the connector 40 is used to attach or limit the alignment member 30 to the sliding member 20, so that the alignment member 30 can move relative to the sliding member 20.

[0068] Figure 9 yes Figure 2 A schematic diagram of the sliding and limiting components of the display screen alignment structure.

[0069] See Figure 2 and Figure 9 The alignment structure of the display screen may also include a limiting member 50 and an adsorption member 60.

[0070] The limiting member 50 is disposed at the axial end of the sliding member 20 and can be limited on the inner wall of the mounting cavity 12, thereby restricting the movement of the sliding member 20 relative to the base 10, and thus preventing the sliding member 20 and the alignment member 30 from moving automatically and causing the alignment end 32 to disengage from the positioning hole 101.

[0071] Specifically, the limiting member 50 can be an elastic member, with one end connected to the end of the sliding member 20 and the other end abutting against the side wall of the mounting cavity 12, so as to restrict the movement of the sliding member 20 relative to the base 10 under elastic action, such as an elastic rubber member.

[0072] In addition, the end of the slider 20 is provided with an end mounting groove 24 for mounting the limiting member 50. At the same time, the adsorption member 60 is fixed in the mounting cavity 12 and located on the side facing the limiting member 50, so that the adsorption member 60 can adsorb the limiting member 50 and restrict the movement of the slider 20 relative to the base 10.

[0073] In some other embodiments, the limiting member 50 can be configured as a snap-fit ​​member, and the adsorption member 60 can be configured as a snap-fit ​​member, so that the limiting member 50 and the adsorption member 60 can engage with each other and restrict the movement of the sliding member 20 relative to the base 10.

[0074] In this embodiment, the limiting member 50 can be a magnetic member, such as a magnet. The adsorption member 60 can be a metal member that can magnetically adsorb onto the magnetic member, allowing the magnetic member to be magnetically attracted to the metal member. The metal member can be a component made of metals such as iron, cobalt, or nickel.

[0075] Specifically, there are two limiting members 50 and two adsorption members 60. The two limiting members 50 are respectively located at both ends of the sliding member 20 along the axial direction, and the two adsorption members 60 are installed on opposite sides of the mounting cavity 12 and are respectively set corresponding to the limiting members 50, so that when the sliding member 20 moves along the axial direction, the limiting members 50 can move towards the adsorption members 60 and be magnetically adsorbed onto the adsorption members 60.

[0076] It should be noted that the adsorption components 60 are respectively installed on both sides of the mounting cavity 12 in the axial direction and cover the two openings of the mounting cavity 12 in the axial direction, so that the adsorption components 60 can be sealed at the openings of the mounting cavity 12.

[0077] Therefore, as Figure 2 As shown, since the limiting member 50 is a magnetic component, when the sliding member 20 moves to the left, the left limiting member 50 is magnetically attracted to the adsorption member 60. At this time, the sliding member 20 cannot move relative to the base 10, and the alignment member 30 retracts into the alignment through hole 11. In addition, since multiple display units 1 are spliced ​​together and mounted on the bracket through the mounting frame 103, the side of the mounting frame 103 facing away from the display module 102 is close to or near the bracket, making the space between the bracket and the mounting frame 103 relatively narrow. This makes it impossible for the operator to operate the display alignment structure in the space between the bracket and the mounting frame 103.

[0078] Therefore, when alignment is required, a magnet is used as the operating tool. It is placed near or against the right-side adsorption member 60 outside the mounting cavity 12. The magnet attracts the limiting member 50 located on the right side of the slider 20 through the attraction between opposite magnetic poles. This causes the right-side limiting member 50 to move the slider 20 to the right, disengaging the left-side limiting member 50 from the left-side adsorption member 60 until the right-side limiting member 50 is magnetically adsorbed onto the right-side adsorption member 60. During the movement of the slider 20 to the right, the alignment member 30 is connected to the slider 20 via the connector 40, and the guide slope 311 is attached to the guide slope 21. This allows the guide slope 21 to push the alignment member 30 out of the alignment through hole 11 and into the positioning hole 101, thus achieving alignment between the two display units 1. Furthermore, since the right-side limiting member 50 is magnetically attracted to the right-side adsorption member 60, it prevents the sliding member 20 from moving automatically, thereby ensuring that the alignment end 32 of the alignment member 30 always extends into the positioning hole 101, preventing the alignment member 30 from automatically disengaging. When disengagement is required, a magnet is used as a tool, placed near or against the right-side adsorption member 60 outside the mounting cavity 12. The magnet can push the limiting member 50 located on the right side of the sliding member 20 through the repulsive property between the two magnetic components, causing the right-side limiting member 50 to push the sliding member 20 to the left, causing the right-side limiting member 50 and the right-side adsorption member 60 to disengage until the left-side limiting member 50 is magnetically attracted to the left-side adsorption member 60. During the movement of the slider 20 to the left, the alignment member 30 is connected to the slider 20 through the connector 40, and the guide slope 311 is attached to the guide slope 21. This allows the slider 20 to drive the alignment end 32 of the alignment member 30 to disengage from the positioning hole 101 and retract into the alignment through hole 11, thereby disengaging the two display units 1 from each other and facilitating the disassembly of the two adjacent display units 1.

[0079] In summary, the display alignment structure includes a base 10, a slider 20, and an alignment member 30. The base 10 is connected to one of two adjacent display units 1, and the base 10 is provided with an alignment through hole 11 and a mounting cavity 12. The slider 20 is housed in the mounting cavity 12 and can move relative to the mounting cavity 12. The alignment member 30 is installed in the alignment through hole 11 and can move relative to the base 10, so that the alignment end 32 of the alignment member 30 can extend out of the alignment through hole 11 and into the positioning hole 101 of the other display unit 1, thereby aligning the two display units 1. Meanwhile, the slider 20 is provided with a guide slope 21, and the connecting end 31 of the alignment member 30 can fit on the guide slope 21 so that when the slider 20 moves relative to the base 10, the connecting end 31 can move along the guide slope 21 and drive the alignment end 32 to extend or retract into the alignment through hole 11 to achieve locking alignment or unlocking, thereby facilitating the installation or removal of the display unit 1.

[0080] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
