Description

Technical Field

[0001] The invention relates to the technical field of LED display screens, and in particular to a mounting structure of an LED display screen capable of preventing a fall. Background Art

[0002] When installing an LED display, you should consider its safety, reliability and ease of maintenance.

[0003] There are two main ways to install LED display screen modules. The first is to install and fix the light board module of the LED display screen by screws. Nut columns are provided on the bottom shell, and through holes are provided on the box body to allow screws to pass through. The light board module is fixed from the back of the box body by screws. Although this method can firmly install the light board module to prevent it from falling, disassembly and maintenance can only be carried out at the back of the box body. In the case of no maintenance channel (for example, directly installed on the wall), it is difficult to maintain.

[0004] The second method is to install the LED display panel module by magnets. Magnets are good for assembly, disassembly and maintenance of the panel module, but the magnets may weaken in high temperature environments (such as outdoors in summer) and fail to attract the panel module, which may cause the panel module to fall. In addition, in strong winds (such as typhoons), insufficient magnet attraction may also cause the panel module to fall. Summary of the invention

[0030] Figure 1 FIG2( a ) is a perspective view of a housing 10 of an LED display screen.

[0031] FIG. 2( b ) is a perspective view of an embodiment of a light board module 20 of an LED display screen, and FIG. 3( a ) is a front view of the LED display screen. Figure 1, FIG2(a), FIG2(b), FIG3(a), the installation structure of the LED display screen includes a box body 10 and a light board module 20, and the light board module 20 is installed on the box body 10. The light board module 20 includes a light board 201 and a bottom shell 202, and the light board 201 includes a PCB board and an LED light-emitting unit arrayed on the PCB board. The light board 201 can be installed on the bottom shell 202 by screws.

[0032] FIG3( b ) is a cross-sectional view of the LED display screen at AA of FIG3( a ). Figure 4 3 (b) B is a partial enlarged view of the installation structure of the LED display screen that can prevent falling, referring to FIG. 3 (b), Figure 4 In order to facilitate the installation of the light board module 20 on the box body 10, in an optional embodiment, the box body 10 is provided with a first support column 11, and the first support column 11 is formed to protrude in a direction perpendicular to the bottom surface 101 of the box body 10. Here, the direction perpendicular to the bottom surface 101 of the box body 10 is set as the Z direction, and the Z direction is the normal direction perpendicular to the bottom surface of the box body 10. The first support column 11 is provided with a first mounting hole 111, and the first mounting hole 111 starts from the upper end surface 11a of the first support column 11 and extends along the axis of the first support column 11 (the opposite direction of the Z direction). Correspondingly, the light board module 20 is provided with a first mounting protrusion 22. Specifically, the first mounting protrusion 22 is provided on the bottom shell 202, and the first mounting protrusion 22 is columnar. The diameter of the first mounting protrusion 22 is slightly smaller than the aperture of the first mounting hole 111, for example, the diameter of the first mounting protrusion 22 is 1mm to 3mm smaller than the aperture of the first mounting hole 111. When the light board module 20 is installed in the box 10, the first mounting protrusion 22 is inserted into the first mounting hole 111, thereby facilitating the position alignment of the light board module 20 and the box 10. In addition, a plurality of first support columns 11 may be provided on the box 10, and each first support column 11 is respectively provided with a first mounting hole 111. Correspondingly, a plurality of first mounting protrusions 22 may also be provided on the light board module 20. In a preferred embodiment, a first spring 112 is disposed in the first mounting hole 111, and when the light board module 20 is installed in the box 10, the first spring 112 is compressed by the first mounting protrusion 22. The first spring 112 may be a round wire coil spring. By providing the first spring 112 compressed by the first mounting protrusion 22, it is possible to achieve that when the light board module 20 is disassembled, the first spring 112 applies a thrust to the bottom shell 202 of the light board module 20, making it easier to disassemble the light board module 20.

[0033] In order to prevent the light board module 20 from falling, the installation structure of the LED display screen of this embodiment includes a first limiting portion 40, which is arranged on the box body 10. The first limiting portion 40 includes a first limiting pin 41. The first limiting pin 41 is configured to be slidably inserted into the light board module 20 and retractable from the sliding light board module 20. After the first limiting pin 41 is inserted into the first accommodating portion 21 arranged on the light board module 20, the disassembly of the light board module 20 is restricted, that is, the movement of the light board module 20 along the Z direction is restricted. The angle between the direction in which the first limiting pin 41 is inserted into the first accommodating portion 21 and the direction in which the light board module 20 is installed on the box body 10 (opposite to the Z direction) is preferably less than or equal to 90 degrees. More preferably, the direction in which the first limiting pin 41 is inserted into the light board module 20 is perpendicular to the direction in which the light board module 20 is installed on the box body 10 (opposite to the Z direction). Here, the direction in which the first limiting pin 41 is inserted into the first accommodating portion 21 in the direction perpendicular to the Z direction is referred to as the Y direction. By inserting the first limiting pin 41 into the first accommodating portion 21 in the Y direction, it is ensured that the first limiting portion 40 can limit the disassembly of the light board module 20 in the opposite direction of the Z direction, and it is also convenient for the release portion 50 described later to release the restriction of the light board module 20 by the first limiting pin 41. Of course, in practice, the angle between the direction in which the first limiting pin 41 is inserted into the light board module 20 and the direction in which the light board module 20 is installed on the box body 10 may also be greater than 90 degrees and less than 180 degrees. However, in this case, other limiting parts need to be set to limit the movement of the light board module 20 in the Y direction.

[0034] In order to facilitate the disassembly and maintenance of the light board module 20, a first connecting portion that can be connected to the first limiting pin 41 is provided on the front of the LED display screen. The first connecting portion may include a first through hole 23. The first limiting pin 41 can be driven to retract at the first through hole 23 (the position where the first limiting pin 41 and the first through hole 23 are connected). The first limiting pin 41 can be driven to retract by a release portion 50. The release portion 50 can pass through the light board module 20 from the front 20a of the LED display screen and abut against the first limiting portion 40, and can retract the first limiting portion 40 from the light board module 20. Here, the front 20a of the LED display screen (auxiliary reference Figure 3 (a)) refers to the display surface of the LED display screen that is exposed to the outside and is used to play various videos, etc. By providing a release portion 50 for releasing the first limiting portion 40 on the front of the LED display screen, the light board module 20 can be easily disassembled.

[0035] FIG. 5(a) is a partial schematic diagram of the installation structure of the LED display screen that can prevent falling, FIG. 5(b) is a schematic diagram of the first limiting pin 41, and FIG. 5(c) is a schematic diagram of the installation cover 13. Referring to FIG. 5(a), FIG. 5(b), and FIG. 5(c), and continuing to refer to Figure 4The following is a detailed description of the installation structure of the anti-falling LED display screen that prevents the light board module 20 from falling by the first limiting portion 40.

[0036] As described above, the first limiting portion 40 includes a first limiting pin 41, and the light board module 20 is provided with a first accommodating portion 21, and the first limiting pin 41 is slidably inserted into the first accommodating portion 21 or slidably retracted from the first accommodating portion 21. The first limiting pin 41 can be slidably mounted on the box body 10 in any known manner. After the light board module 20 is mounted on the box body 10, the first accommodating portion 21 and the first limiting pin 41 are opposite in the Y direction. In an optional embodiment, the box body 10 is provided with a first guide portion 113, and the first limiting pin 41 is at least partially disposed in the first guide portion 113 and is slidable in the first guide portion 113. Specifically, the first guide portion 113 can be a first guide hole set through the side wall 11b of the first support column 11, that is, the first guide hole serving as the first guide portion 113 is connected to the first mounting hole 111, and the front end portion of the first limiting pin 41 is slidably mounted on the side wall 11b of the first support column 11 along the radial direction (Y direction) of the first support column 11, and the first accommodating portion 21 is arranged on the first mounting protrusion 22 of the light board module 20. When the first mounting protrusion 22 is inserted into the first mounting hole 111, the first limiting pin 41 can be squeezed to slide toward the radial outer side (that is, the opposite direction of the Y direction) of the first support column 11, so that the light board module 20 can be installed on the box body 10. When the light board module 20 is installed on the box body 10, the first accommodating portion 21 is accommodated in the first mounting hole 111 and is connected to the first guide portion 113, and the first accommodating portion 21 is opposite to the first limiting pin 41 in the Y direction. At this time, the first limiting pin 41 can slide toward the radial inner side (Y direction) of the first support column 11 and be inserted into the first accommodating portion 21, and limit the first mounting protrusion 22 from being detached from the first mounting hole 111, that is, showing the movement of the first mounting protrusion 22 along the Z direction, thereby limiting the disassembly of the light board module 20.

[0037] As described above, when the first mounting protrusion 22 is inserted into the first mounting hole 111 , it can press the first limiting pin 41 to slide radially outward of the first support column 11 , that is, the first mounting protrusion 22 can drive the first limiting pin 41 to slide. In an optional embodiment, the first limiting pin 41 includes a first section 411 inserted into the first accommodating portion 21, the first section 411 is located at the front end of the first limiting pin 41, and the first section 411 is provided with a hemispherical, arc-shaped, or inclined first guide surface 411a. In the initial state, the first section 411 passes through the first guide portion 113 and is exposed in the first mounting hole 111. When the first mounting protrusion 22 is inserted into the first mounting hole 111, it first abuts against the first guide surface 411a of the first section 411 and slides along the first guide surface 411a. At the same time, the first mounting protrusion 22 squeezes the first section 411, so that the first limiting pin 41 as a whole retracts toward the first guide portion 113. When the first accommodating portion 21 is opposite to the first guide portion 113, since the first mounting protrusion 22 no longer squeezes the first section 411, the first limiting pin 41 extends out from the first guide portion 113 again and is inserted into the first accommodating portion 21. The shape of the first accommodating portion 21 is a concave shape that matches the shape of the first section 411. For example, when the first section 411 is hemispherical, the first accommodating portion 21 is also hemispherical and concave; when the first section 411 is arc-shaped or inclined, the first accommodating portion 21 is also arc-shaped or inclined.

[0038] In this embodiment, the first limiting pin 41 is retracted by squeezing the first mounting protrusion 22. As for the extension of the first mounting protrusion 22 from the first guide portion 113, for example, a spring mechanism can be provided to allow the first limiting pin 41 to extend from the first guide portion 113. In an optional embodiment, the first limiting portion 40 further includes a second spring 42, which drives the first limiting pin 41 to slide into the first accommodating portion 21. The second spring 42 is inserted into the first limiting pin 41, one end of the second spring 42 abuts against the first limiting pin 41, and the other end abuts against the box body 10. In the installed state, the second spring 42 can push the first limiting pin 41 and make the first section 411 appear in the first mounting hole 111, thereby, although the first limiting pin 41 can be retracted by squeezing the first mounting protrusion 22, when the position of the first accommodating portion 21 is opposite to the position of the first guide portion 113, the first limiting pin 41 can automatically extend and be inserted into the first accommodating portion 21 under the action of the second spring 42. Here, when the light board module 20 is installed to the box body 10, the installation stroke of the light board module 20 is usually long relative to the first limiting portion 41. In this process, the first limiting pin 41 can be easily retracted by the weight of the light board module 20 and the dynamic potential energy generated when the light board module 20 is installed, which is convenient for the installation of the light board module 20. In the installed state, since the first section 411 of the first limiting pin 41 has been inserted into the first receiving portion 21 of the first installation protrusion 22, the movable stroke of the light board module 2 is very short relative to the first limiting portion 40, so it is difficult to retract the first limiting pin 41. Therefore, the first limiting portion 40 has a very obvious effect on preventing the light board module 20 from falling, and can prevent the light board module 20 from accidentally falling. In addition, when the output force of the second spring 42 is adjusted (for example, the wire diameter of the second spring 42 is increased), the force of the first limiting pin 41 inserted into the first receiving portion 21 can be further increased.

[0039] In order to firmly support the first limiting pin 41, the box body 10 may be provided with a second supporting column 12 beside the first supporting column 11, and the second supporting column 12 is provided with a second guide hole 121 coaxial with the first guide hole as the first guide portion 113, and the front end portion (including the first section 411) of the first limiting pin 41 slides in the first guide portion 113, and the rear end portion of the first limiting pin 41 slides in the second guide hole 121. In addition, in order to facilitate the removal of the first limiting pin 41, an installation cover plate 13 for installing the first limiting pin 41 may also be included, and the installation cover plate 13 is installed on the second supporting column 12 and extends to the first supporting column 11. The front end of the installation cover plate 13 is provided with a semicircular first opening 131, and the side wall 11b of the upper end surface 11a of the first support column 11 is formed with a semicircular second opening 113a with the same radius as the first opening 131. When the installation cover plate 13 is installed on the second support column 12, the first opening 131 and the second opening 113a together form a first guide hole with a closed cross section, and the second guide hole 121 can also be formed in the same way. Therefore, after the installation cover plate 13 is removed, the first limiting pin 41 is easily removed from the first support column 11 and the second support column 12, and the disassembly is very convenient.

[0040] The following describes in detail the structure in which the restriction of the first restriction part 40 on the light board module 20 is released by the release part 50 .

[0041] The front of the light board module 20 is provided with a first through hole 23 (auxiliary reference figure 3(a)). The positions of the first through hole 23 and the first limiting part 40 can be pre-designed. As long as the first through hole 23 does not pass through some PCB boards and LED light-emitting units of the light board 201, the first through hole 23 and the first limiting part 40 can be set at any position of the LED display screen. The first through hole 23 is connected to the first limiting part 40. The release part 50 includes a first rod-shaped driving member 51. The first driving member 51 can abut against the first limiting pin 41 through the first through hole 23. The release part 50 retracts the first limiting pin 41 from the first accommodating portion 21 through the first driving member 51, thereby releasing the restriction of the light board module 20 by the first limiting part 40. By opening the first through hole 23 on the top of the light board module 20, it is convenient for the release part 50 to release the restriction of the first limiting part 40 on the light board module 20 from the front 20a of the LED display screen, and disassembly is very convenient. In an optional embodiment, a first inclined portion 412 is provided on the first limiting pin 41, and the first driving member 51 abuts against the first inclined portion 412 via the first through hole 23, and can slide on the first inclined portion 412, thereby squeezing the first inclined portion 412 and retracting the first limiting pin 41. After the first limiting portion 40 is retracted, the light board module 20 can be disassembled. In addition, it should be noted that, here, the release portion 50 is a detachable component relative to the light board module 20, such as a screwdriver, etc., and does not need to be left on the light board module 20. It is only necessary to pass the release portion 50 through the first through hole 23 to abut against the first limiting portion 40 and release it during disassembly.

[0042] FIG6(a) is a schematic diagram of another embodiment of the installation structure of the LED display screen that can prevent falling, and FIG6(b) is a schematic diagram of the first limiting pin in the embodiment of FIG6(a). Referring to FIG6(a) and FIG6(b), the first limiting portion 60 of another embodiment is described below. The first segment 611 of the first limiting pin 61 of the first limiting portion 60 can be provided with a first guide surface 611a only on the side opposite to the installation direction (opposite to the Z direction) of the light board module 20, and a first stop surface 611b cut out parallel to the axial direction of the first limiting pin 61 is provided on the side opposite to the disassembly direction (Z direction) of the light board module 20. In contrast, the first accommodation portion 21a is also provided as a concave portion matching the shape of the first segment 611, that is, the upper surface is hemispherical, arc-shaped or inclined, and the lower surface is a plane that can fit with the first stop surface 611b. In this embodiment, since the first limiting pin 61 of the first limiting portion 60 and the lower side of the first accommodating portion 21a of the light board module 20 are flatly fitted, the first limiting pin 61 cannot be squeezed to retract during disassembly, and therefore, the limiting effect of the first limiting portion 60 on preventing the light board module 20 is more obvious. In this embodiment, in order to prevent the first limiting pin 61 from rotating, the bottom surface of the second opening 113b provided on the first support column 11 can be a plane, and the first stop surface 611b can slide on the bottom surface of the second opening 113b. At this time, the first guide portion 113 is actually a chamfered circular hole, and therefore, the first limiting pin 61 can be prevented from rotating.

[0043] FIG. 7(a) is a schematic diagram of another embodiment of the installation structure of the LED display screen that can prevent falling, and FIG. 7(b) is a schematic diagram of the first limiting pin 71 in the embodiment of FIG. 7(a). Referring to FIG. 7(a) and FIG. 7(b), the first limiting portion 70 of another embodiment is described below. In this embodiment, a step portion 711 is provided on the first limiting pin 71 of the first limiting portion 70, and in contrast, there is a gap between the first through hole 23 and the first driving member 51, for example, the first through hole 23 is a U-shaped hole. The first driving member 51 passes through the first through hole 23 of the U-shaped hole, and the first driving member 51 abuts against the first limiting pin 71. When the first driving member 51 is pushed in the direction in which the first limiting pin 71 is retracted, the radial outer side of the first driving member 51 abuts against the side 711a of the step portion 711, and the first limiting pin 71 can be pushed to compress the second spring 42 and retract from the first accommodating portion 21 to the first guide portion 113. After the first limiting portion 70 is retracted, the lamp assembly module 20 can be easily disassembled relative to the box body 10.

[0044] FIG8(a) is a schematic diagram of another embodiment of the installation structure of the LED display screen that can prevent falling, and FIG8(b) is a schematic diagram of the first limiting pin 81 in the embodiment of FIG8(a). Referring to FIG8(a) and FIG8(b), the first limiting portion 80 of another embodiment is described below. In this embodiment, an annular groove portion 811 is provided on the first limiting pin 81 of the first limiting portion 80, and in contrast, there is a gap between the first through hole 23 and the first driving member 51, for example, the first through hole 23 is a U-shaped hole. The first driving member 51 passes through the first through hole 23 of the U-shaped hole, and the first driving member 51 abuts against the annular groove portion 811 of the first limiting pin 81. In this embodiment, the first driving member 51 can push the first limiting pin 81 to extend or retract. In addition, in this embodiment, the spring may not be provided. In order to clamp the first limiting pin 81, a locking protrusion 812 may be provided on the first limiting pin 81. Correspondingly, a locking groove 114 may be provided in the first guide portion 113. When the first limiting pin 81 is inserted into the first accommodating portion 21, the locking protrusion 812 is locked in the locking groove 114, thereby preventing the first limiting pin 81 from sliding in the first guide portion 113. In order to make it easier for the first driving member 51 to push the first limiting pin 81, the mounting cover 13 may be provided as an elastic member, such as a stainless steel sheet metal member.

[0045] In the above embodiment, although the embodiment in which the first limiting portion 40 is provided on the housing 10 and the first limiting pin 41 is provided to be slidably inserted into the light board module 20 is described in detail. However, the first limiting portion (not shown) may also be provided on the light board module 20, and the first limiting pin of the first limiting portion may be provided to be slidably inserted into the first accommodating portion of the housing 10 and may be retracted from the slidable housing 10, and when the first limiting portion is inserted into the first accommodating portion of the housing 10, the disassembly of the light board module 20 is restricted. Similarly, the release portion 50 may pass through the light board module 20 from the front of the LED display screen and abut against the first limiting portion 40, and retract the first limiting portion 40 from the light board module 20.

[0046] Continuing to refer to FIG. 2(a), in addition, in order to further enhance the anti-falling effect of the installation structure of the LED display screen, a plurality of first magnet mounting seats 102 are provided on the box body 10, and the first magnet 30 is fixed to the first magnet mounting hole 102 of the box body 10. The first magnet 30 can be distributed in multiple places as needed. For example, if the box body 10 is square or rectangular, the first magnet 30 is distributed in multiple places at each edge of the box body 10. The bottom shell 202 is provided with components such as iron sheets 203 that can be adsorbed by the first magnet 30. When the light board module 20 is installed on the box body 10, the light board module 20 is adsorbed by the first magnet 30 installed on the box body 10, thereby being fixed.

[0047] The various specific technical features described in the above specific embodiments can be combined in any way without contradiction. To avoid unnecessary repetition, the present invention does not separately explain various possible combinations.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention but not to limit the same. Any modification or equivalent substitution that does not depart from the scope of the present invention shall be included in the technical solutions of the present invention.
