DETAILED DESCRIPTION

[0030] Typical embodiments that embody 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 changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

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

[0032] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] In the field of LED display technology, the conventional design solution for solving the step difference in the mid-to-high-end market is: to design a matching cabinet, and the cabinet itself maintains a high degree of flatness through CNC processing. At the same time, the cabinet is designed with up and down or left and right connection structures (such as positioning columns and positioning hole structures) to ensure the splicing step difference between cabinets. In addition, the display unit is installed on the cabinet by screw connection or magnet attraction. The height difference between the display unit and the cabinet is adjusted by adjusting the connection position of the screw or magnet, so as to minimize the step difference when the display unit is spliced. However, this method of preventing step difference is costly and easily affects the splicing efficiency of the display unit.

[0034] In the mid- and low-end markets, there are also display units without a box design or non-load-bearing display units. Specifically, the display unit is equipped with a magnet, which is magnetically attracted to the steel structure, and the height or thickness of the magnet on the display unit is adjusted to adjust the splicing step difference. However, since the steel structure is relatively bulky and due to cost constraints, it is usually only arranged vertically, so there is a step difference problem at the horizontal joints of the display unit. In addition, most of the application scenarios of this design do not have rear maintenance space, and it is necessary to consider front installation and front maintenance. In addition, due to the need to take into account the detachability and maintainability of the display unit, it is impossible to design an ordinary positioning column based on the above solution to solve the problem of the splicing step difference of the display unit.

[0035] Therefore, the existing positioning structure alignment structure easily affects the splicing efficiency of the display unit, thereby affecting the assembly or disassembly of the display unit, which is not conducive to the use and maintenance of the LED display screen. Therefore, in view of the anti-step difference problem of the non-box design or non-load-bearing display unit, and taking into account the problems of front maintenance and front installation, a display screen alignment structure is proposed to solve the above problems.

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

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

[0038] See also Figure 1 and Figure 2 The LED display screen of this embodiment may include a plurality of display units 1 and a display screen alignment structure. Specifically, the plurality of display units 1 may be spliced ​​to form an integral LED display screen.

[0039] In this embodiment, the display unit 1 may include a display module 102 and a mounting frame 103, and the display module 102 is fixed on the mounting frame 103. At the same time, a positioning hole 101 is opened on the display unit 1, and a display screen alignment structure is set on the display unit 1, that is, a positioning hole 101 is opened on the mounting frame 103, and the display screen alignment structure is set on the mounting frame 103. Among them, the display module 102 can be set as an LED module or other display elements. The mounting frame 103 can be set as a metal frame or a plastic frame for mounting the display module 102.

[0040] Therefore, when multiple display units 1 are spliced, the alignment member 30 of the display screen 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) and ensure the flatness between the two display units 1, so as to avoid causing a bad visual effect to the user.

[0041] It should be noted that each side of the display unit 1 may 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 be spliced ​​into an integral display screen.

[0042] In actual use, the LED display screen can be spliced ​​by multiple display units 1 in a nine-square grid shape, or can be spliced ​​by multiple display units 1 in a rectangular shape or a 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 provided correspondingly, and when multiple display units 1 are spliced, each side of adjacent display units 1 may be aligned by at least two display screen alignment structures, thereby avoiding step differences between two adjacent display units 1.

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

[0045] The base 10 may be connected to the display unit 1, or the base 10 may be formed on the display unit 1. That is, the base 10 may be connected to the mounting frame 103 of the display unit 1 by welding or screw connection, or the base 10 may 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 can be connected to 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 arranged at a right angle 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 installation cavity 12 may also be set at other angles, such as 45°, 60°, etc.

[0048] The sliding member 20 can be accommodated in the installation cavity 12 and can move relative to the base 10. Specifically, the sliding member 20 can move along the axis of the installation cavity 12, so that the sliding member 20 can reciprocate along the axial direction of the installation cavity 12. Of course, in some other embodiments, the sliding member 20 can also rotate back and forth around the axis of the installation cavity 12.

[0049] The alignment member 30 can be disposed in the alignment through hole 11, and the two axial ends of the alignment member 30 are respectively provided with a connecting end 31 and an alignment end 32. The alignment member 30 can move relative to the base 10, so that the alignment end 32 can extend out of the alignment through hole 11 and extend into the positioning hole 101 on the other display unit 1, so that the two adjacent display units 1 can be aligned and the step difference between the two adjacent display units 1 can be avoided.

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

[0051] In this embodiment, the guiding inclined surface 21 is inclined from the central axis of the sliding member 20 toward a direction away from the axis in the axial direction of the sliding member 20 , so that when the sliding member 20 moves along the axial direction, the aligning member 30 can move relative to the sliding member 20 along the guiding inclined surface 21 .

[0052] Of course, in some other embodiments, the guide slope 21 is inclined from the central axis of the sliding member 20 in the radial direction toward the direction away from the axis, so that when the sliding member 20 rotates around the axis of the installation cavity 12, the alignment member 30 can move relative to the sliding member 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 sliding member 20 rotates, the connecting end 31 abuts against the guide slope 21, that is, the sliding member 20 can rotate smoothly, and can drive the alignment member 30 to move in the direction away from or close to the central axis of the sliding member 20.

[0053] Therefore, when the sliding member 20 moves relative to the base 10, the connecting end 31 can move along the guiding bevel 21 to drive the aligning end 32 of the aligning member 30 to extend out of the aligning through hole 11 or retract into the aligning through hole 11. For example, when the sliding member 20 moves relative to the base 10 along a certain direction of the axial direction of the installation cavity 12, the sliding member 20 can drive the aligning member 30 to move through the guiding bevel 21, and make the aligning end 32 extend out of the aligning through hole 11 and extend 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 sliding member 20 moves relative to the base 10 in the opposite direction, the sliding member 20 can drive the aligning member 30 to disengage from the positioning hole 101 through the guiding bevel 21 and retract into the aligning through hole 11, thereby facilitating the disassembly of the two display units 1.

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

[0055] See also Figure 2 and Figure 3 , a guiding bevel 311 may be provided on the connecting end 31. The inclination direction of the guiding bevel 311 is the same as the inclination direction of the guiding bevel 21, so that the guiding bevel 311 can be matched with the guiding bevel 21, and then the guiding bevel 311 can be pressed against the guiding bevel 21 and move relative to the guiding bevel 21. It should be noted that the guiding bevel 311 can be fitted on the guiding bevel 21, which can increase the contact area between the guiding bevel 311 and the guiding bevel 21, and improve the stability of the connection between the sliding member 20 and the alignment member 30, so as to avoid shaking of the alignment member 30 when the relative movement of the sliding member 20 occurs.

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

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

[0058] The connecting member 40 is connected between the sliding member 20 and the alignment member 30 to fit or limit the guiding inclined surface 311 on the guiding inclined surface 21, so that the alignment member 30 can move with the sliding member 20. That is, the connecting member 40 is used to fit or limit the guiding inclined surface 311 on the guiding inclined surface 21, so that when the sliding member 20 moves, the guiding inclined surface 311 can always fit or connect to the end 31, and when the sliding member 20 moves, the alignment member 30 can also move relative to the sliding member 20, so that the alignment end 32 can extend or retract into the alignment through hole 11.

[0059] Meanwhile, a guide portion 22 may be provided on the sliding member 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 connecting member 40 can be connected to the guide portion 22 and can move along the guide portion 22, so that the guide slope 311 is limited or attached to the guide slope 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 connecting member 40 can be connected to the guide portion 22 and can slide along the guide portion 22.

[0061] See also Figure 6 and Figure 7 In this embodiment, the sliding member 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 guiding portion 22, and the other end is connected to the shaft end 26, and the guiding portion 22 is connected to the other shaft end 26 on one side relative to the connecting portion 25. In addition, 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 side wall of the shaft end 26, so that the connecting portion 25 deviates from the central axis of the shaft end 26, so that an escape space 27 is formed between the shaft end 26 and the guiding portion 22, that is, an escape space 27 is formed between the side of the guiding portion 22 away from the guiding inclined surface 21 and the shaft end 26, for escaping the connecting member 40. At the same time, since the guiding inclined surface 21 is inclined, a moving space 28 is also formed between the guiding inclined surface 21 and the adjacent shaft end 26, so that the positioning member 30 can move relative to the sliding member 20 in the moving space 28. Specifically, the sliding member 20 generally presents a “Z”-shaped structure.

[0062] It should be noted that a limiting portion 29 may also be provided on the sliding member 20. The limiting portion 29 is a straight cutting plane, so that the limiting portion 29 can abut against the abutting structure of the mounting cavity 12 to limit the rotation of the sliding member 20 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 2Schematic diagram of the connecting parts of the display screen alignment structure.

[0064] See also Figure 4 , Figure 6 and Figure 8 The guide portion 22 may be provided with a through guide groove 23 so that the connector 40 can be inserted into 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 butt-joint top portion 41, which can butt against the side of the guide portion 22 away from the guide slope 21, so as to fit the guide slope 311 onto the guide slope 21.

[0065] In this embodiment, the connecting member 40 can be configured as a step screw, and the step screw includes a nut, a step portion 42 and a threaded portion 43. The nut is abutting the top portion 41, the step portion 42 is inserted into the guide groove 23, so that the step screw can move along the guide groove 23, and the threaded portion 43 is used to connect to the connecting end 31, so that the step screw can be fastened together with the alignment member 30, and the alignment member 30 is attached to or limited on the guide slope 21.

[0066] In some other embodiments, the connecting member 40 can be configured as a clamping member, and the abutting top portion 41 can be configured as a claw of the clamping member, so that the abutting top portion 41 can be engaged on both radial sides of the guide portion 22, thereby fitting or limiting the positioning member 30 on the guide slope 21.

[0067] It should be noted that if Figure 2 As shown, a mounting hole is provided on the base 10 to facilitate the installation of the connecting member 40 , that is, the aligning member 30 is attached or limited on the sliding member 20 through the connecting member 40 , and the aligning member 30 can move relative to the sliding member 20 .

[0068] Fig. 9 yes Figure 2 Schematic diagram of the sliding parts and the limiting parts of the display screen alignment structure.

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

[0070] Among them, the limit member 50 is arranged at the axial end of the sliding member 20 and can be limited on the inner wall of the installation cavity 12, so as to limit the movement of the sliding member 20 relative to the base 10, thereby preventing the sliding member 20 and the alignment member 30 from automatically moving and causing the alignment end 32 to disengage from the positioning hole 101.

[0071] Specifically, the limit member 50 can be an elastic member, and one end of the elastic member is connected to the end of the sliding member 20, and the other end abuts against the side wall of the installation cavity 12 to limit the movement of the sliding member 20 relative to the base 10 under elastic action, such as an elastic rubber member.

[0072] In addition, an end mounting groove 24 is provided at the end of the sliding member 20 for mounting the stopper 50. At the same time, the adsorption member 60 is fixed in the mounting cavity 12 and is located on a side facing the stopper 50, so that the adsorption member 60 can adsorb the stopper 50 and limit the movement of the sliding member 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 buckle member, so that the limiting member 50 and the adsorption member 60 can be engaged with each other and limit the movement of the sliding member 20 relative to the base 10.

[0074] In this embodiment, the stopper 50 can be set as a magnetic member, such as a magnet. The adsorption member 60 can be set as a metal member that can be magnetically adsorbed with the magnetic member, so that the magnetic member can be adsorbed on the metal member by magnetic attraction. Among them, the metal member can be made of metal materials such as iron, cobalt, and nickel.

[0075] Specifically, two stoppers 50 and two adsorbents 60 are provided. The two stoppers 50 are respectively provided at two ends of the axial direction of the sliding member 20, and the two adsorbents 60 are installed on two opposite sides of the installation cavity 12, and are respectively provided corresponding to the stoppers 50, so that when the sliding member 20 moves along the axial direction, the stoppers 50 can move toward the adsorbents 60 and be adsorbed on the adsorbents 60 by magnetic attraction.

[0076] It should be noted that the adsorption member 60 is respectively installed on both sides of the axial direction of the installation cavity 12 and covers the two axial openings of the installation cavity 12 so that the adsorption member 60 can be closed at the opening of the installation cavity 12.

[0077] Therefore, if Figure 2 As shown, since the stopper 50 is a magnetic part, when the sliding member 20 moves to the left, the stopper 50 on the left side is adsorbed on the adsorption member 60 by magnetic attraction, and 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 mounted on the bracket through the mounting frame 103 after being spliced, the mounting frame 103 is attached to or close to the bracket on the side away from the display module 102, so that the space between the bracket and the mounting frame 103 is relatively narrow, so that the operator cannot operate the display screen alignment structure in the space between the bracket and the mounting frame 103.

[0078] Therefore, when the alignment operation is required, a magnet is used as an operating tool, and is placed outside the installation cavity 12 close to or attached to the right side adsorption member 60, so that the magnet can attract the limiting member 50 located on the right side of the sliding member 20 through the opposite attraction characteristics between the two magnetic members, so that the limiting member 50 on the right side drives the sliding member 20 to move to the right, and the limiting member 50 on the left side and the adsorption member 60 on the left side are separated from adsorption, until the limiting member 50 on the right side is adsorbed on the right side adsorption member 60 through magnetic attraction. In the process of the sliding member 20 moving to the right, since the alignment member 30 is connected to the sliding member 20 through the connecting member 40, and the guiding inclined surface 311 is attached to the guiding inclined surface 21, the guiding inclined surface 21 can push the alignment member 30 to extend out of the alignment through hole 11 and extend into the positioning hole 101, thereby realizing the 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, the automatic movement of the sliding member 20 can be avoided, thereby ensuring that the alignment end 32 of the alignment member 30 always extends into the positioning hole 101, and avoiding the alignment member 30 from automatically being out of alignment. When it is necessary to be out of alignment, a magnet is used as a tool to approach or fit the right-side adsorption member 60 outside the installation cavity 12, so that the magnet can push the limiting member 50 located on the right side of the sliding member 20 through the property of repulsion between like-sex members between the two magnetic members, so that the right-side limiting member 50 pushes the sliding member 20 to move to the left, so that the right-side limiting member 50 and the right-side adsorption member 60 are out of adsorption, until the left-side limiting member 50 is adsorbed on the left-side adsorption member 60 through magnetic attraction. During the movement of the sliding member 20 to the left, since the alignment member 30 is connected to the sliding member 20 through the connecting member 40 and the guiding slope 311 is attached to the guiding slope 21, the sliding member 20 can 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 alignment, thereby facilitating the disassembly of the two adjacent display units 1.

[0079] In summary, the display screen alignment structure includes a base 10, a sliding member 20 and an alignment member 30, wherein the base 10 is connected to one of two adjacent display units 1, and an alignment through hole 11 and a mounting cavity 12 are provided on the base 10, the sliding member 20 is accommodated 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 extend into the positioning hole 101 of the other display unit 1, thereby aligning the two display units 1. At the same time, a guiding slope 21 is provided on the sliding member 20, and the connecting end 31 of the alignment member 30 can be fitted on the guiding slope 21, so that when the sliding member 20 moves relative to the base 10, the connecting end 31 can move along the guiding slope 21 and drive the alignment end 32 to extend or retract the alignment through hole 11 to achieve locking or unlocking, thereby facilitating the installation or disassembly of the display unit 1.
