Technical Field

[0001] This utility model relates to the field of display device technology, and in particular to a mask structure and display device. Background Technology

[0002] In the field of LED display equipment, outdoor displays operate in harsh environments, especially at high temperatures. The display modules generate a lot of heat, causing the mask on the display module to deform due to the heat. Existing masks are connected to the display module by multiple screws arranged in a matrix. The arrangement of the screw matrix and the arrangement of the mask's lamp holes are aligned, which easily leads to deformation and bulging of the mask at the center of the four screws. Currently, the bulging phenomenon is generally suppressed by adding more screws or replacing the mask with one that has better heat resistance. However, regardless of the solution, it will significantly increase the equipment cost and maintenance cost. Utility Model Content

[0029] Example 1

[0030] Combination Figures 1 to 5 As shown, the mask structure of this utility model is schematically displayed, including a body 10, which is a plate-shaped cuboid structure.

[0031] like Figure 2 The main body 10 has at least four mounting holes 20 and multiple recess holes 30 arranged in a matrix on the same surface. The main body 10 can cover the display module 80. The LEDs on the display module 80 pass through or into the recess holes 30. The recess holes 30 allow the light emitted by the LEDs on the display module 80 to pass through the main body 10. The mounting holes 20 are used to connect the display module 80 and the main body 10 by existing fasteners such as screws or bolts.

[0032] At least four mounting holes 20 are located at the four corners of a reference rhombus 70. The plane of the reference rhombus 70 is parallel to the body 10. The sides of the reference rhombus 70 are inclined to the transverse or longitudinal direction of the plurality of clearance holes 30. In other words, the matrix arrangement of clearance holes 30 has a plurality of clearance holes 30 arranged in the transverse direction of the matrix, and also has a plurality of clearance holes 30 arranged in the longitudinal direction of the matrix. The sides of the reference rhombus 70 are inclined to the transverse direction of the matrix, or the sides of the reference rhombus 70 are inclined to the longitudinal direction of the matrix.

[0033] The LEDs on the display module 80 emit light and generate heat. The heat generated by the display module 80 bakes the body 10. Regardless of the material used to make the body 10 (generally plastic), the body 10 will deform to some extent when heated. The matrix-arranged clearance holes 30 on the body 10 form a grid-like structure. The grid-like structure can provide forces (denoted as the first tensile force) to resist the thermal deformation of the body 10 in the horizontal and vertical directions of the matrix. The mounting holes 20 arranged at the four corners of the reference rhombus 70 can provide forces (denoted as the second tensile force) to resist the thermal deformation of the body 10 in the direction extending along the diagonal of the reference rhombus 70. The first tensile force and the second tensile force are superimposed to prevent the formation of a bulge deformation of the body 10 at the center of the reference rhombus 70.

[0034] In this embodiment, the distance between the center of the reference rhombus 70 and the four corners of the reference rhombus 70 is equal, that is, the two diagonals of the reference rhombus 70 have the same length, and the tension on the two diagonals is relatively balanced, which can prevent the body 10 from bulging due to heat to the greatest extent.

[0035] Combination Figure 1 , Figure 2 and Figure 4 As shown, to further improve the rigidity of the body 10, the body 10 is provided with multiple first reinforcing ribs 40 and multiple second reinforcing ribs 50. Multiple clearance holes 30 are arranged laterally parallel to the first reinforcing ribs 40 and longitudinally parallel to the second reinforcing ribs 50, meaning the first reinforcing ribs 40 and second reinforcing ribs 50 are perpendicular to each other. Any two adjacent first reinforcing ribs 40 and any two adjacent second reinforcing ribs 50 are arranged around a clearance hole 30. The multiple first reinforcing ribs 40 and multiple second reinforcing ribs 50 form a grid structure, improving the overall rigidity of the body 10 and preventing thermal deformation. The mounting hole 20 is located at the intersection between the first reinforcing ribs 40 and the second reinforcing ribs 50, allowing the force applied to the mounting hole 20 by existing fasteners such as screws or bolts to be transmitted to the body 10 through the first reinforcing ribs 40 and the second reinforcing ribs 50, further preventing thermal deformation of the body 10.

[0036] Furthermore, the main body 10 is provided with a mounting boss 60, which is located at the intersection between the first reinforcing rib 40 and the second reinforcing rib 50, and connects the first reinforcing rib 40 and the second reinforcing rib 50. A mounting hole 20 is formed on the mounting boss 60. The mounting boss 60 can improve the strength of the main body 10 around the mounting hole 20. The first reinforcing rib 40 and the second reinforcing rib 50 are connected into a whole through the mounting boss 60, resulting in higher structural strength and preventing tearing at the intersection between the first reinforcing rib 40 and the second reinforcing rib 50. The height of the mounting boss 60 is the same as the height of the second reinforcing rib 50.

[0037] The main body 10, the first reinforcing rib 40, and the second reinforcing rib 50 are preferably integrally formed, which can not only greatly enhance the rigidity of the main body 10, but also facilitate production and manufacturing.

[0038] like Figure 5 The height of the first reinforcing rib 40 is greater than the height of the second reinforcing rib 50. The first reinforcing rib 40 can not only improve the strength of the body 10, but also serve as a brim structure. The brim structure protruding from the body 10 can not only protect the LED in the clearance hole 30, but also block the light emitted by the LED in a specific direction, thus playing a directional light-blocking role and preventing the light emitted by the display module 80 from being scattered to non-designed directions.

[0039] In this embodiment, as Figure 4 The first reinforcing rib 40 located between two adjacent clearance holes 30 includes a first brim component 41 and a second brim component 42 arranged opposite to each other. The height of the first brim component 41 is greater than the height of the second brim component 42. The first brim component 41 is positioned towards one of the clearance holes 30, and the second brim component 42 is positioned towards the other clearance hole 30. For the clearance hole 30 located in the middle of the matrix, the first brim component 41 is provided on one side of the clearance hole 30, and the second brim component 42 is provided on the other side. The first brim component 41 and the second brim component 42 respectively can achieve the following: the light blocking amount of the first brim component 41 is greater than the light blocking amount of the second brim component 42, that is, the light blocking amount is inconsistent for different directions, which can meet the needs of more scenarios; moreover, the first brim component 41 or the second brim component 42 can be closer to the center (LED bead) of the clearance hole 30, which can achieve a greater light blocking amount at a lower height, save the material of the first reinforcing rib 40, and reduce the weight of the entire body 10.

[0040] To further save material on the first reinforcing rib 40 and reduce the weight of the body 10, a gap 43 is provided between the first brim component 41 and the second brim component 42 of the first reinforcing rib 40.

[0041] Example 2

[0042] like Figure 4As shown, a notch 44 is provided on the first reinforcing rib 40. The distance between the bottom surface of the notch 44 and the body 10 is greater than the distance between the top surface of the second reinforcing rib 50 and the body 10. In this structure, the notch 44 can reduce material consumption and lighten the weight of the body 10.

[0043] Example 3

[0044] like Figure 1 and Figure 3 This embodiment discloses a display device 1, including a display module 80 and a mask structure as described above. The main body 10 is connected to the display module 80 via existing screws or other fasteners passing through mounting holes 20 on the main body 10. The display module 80 has multiple LEDs, each corresponding to a clearance hole 30. The LEDs are located within the clearance holes 30, allowing the light emitted by the LEDs to pass through the main body 10. The LEDs in the display module 80 emit light and generate heat. The main body 10 with the clearance holes 30, together with the diamond-shaped mounting holes 20, resists heat deformation of the main body 10, preventing bulging of the main body 10.

[0045] In summary, the same side of the body 10 has multiple mounting holes 20 and multiple recess holes 30 arranged in a matrix. The recess holes 30 are used to pass through existing light-emitting elements, while the mounting holes 20 can pass through existing screws to fasten the body 10 to the existing display module 80. The four mounting holes 20 are located at the four corners of a reference rhombus 70, and the sides of the reference rhombus 70 are inclined to the horizontal or vertical direction of the matrix of recess holes 30. This allows the body 10 with recess holes 30 to work together with the rhomboid mounting holes 20 to resist the thermal deformation of the body 10 and prevent the formation of bulges.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
