[0036] Example 1

[0037] Combination Figure 1 and Figure 7 As shown, the mounting structure of the utility model is schematically shown, which is suitable for connecting a display module 30 to a mounting surface 20. The mounting structure includes a mounting plate 10, which is made of a light-transmissive material, such as transparent plastic. The mounting plate 10 is preferably a rectangular parallelepiped structure, which has a front face 11, a back face 12, two end faces and two side faces.

[0038] The front surface 11 of the mounting plate 10 is used to fit the mounting surface 20, wherein the mounting plate 10 can be bonded to the mounting surface 20 by using existing glue, or an adhesive layer 17 can be provided on the front surface 11 of the mounting plate 10, and the adhesive layer 17 is used to be bonded to the mounting surface 20, and the mounting surface 20 can be an existing glass or an existing acrylic plate, which is not limited here. In practical applications, the mounting plate 10 can be permanently bonded to the mounting surface 20.

[0039] like Figure 7 , the back side 12 of the mounting plate 10 is provided with a connecting component, which is detachably connected to the display module 30. Therefore, the display module 30 is installed on the mounting surface 20 through the mounting plate 10. When the display module 30 needs to be maintained, it is only necessary to remove the display module 30 from the connecting component, and there is no need to peel off the mounting plate 10 from the mounting surface 20. There is no difficulty in bonding or difficulty in removing residual glue in the prior art. In addition, when the mounting plate 10 is bonded to the mounting surface 20, the position of the mounting plate 10 on the mounting surface 20 is precisely controlled, and the remaining display module 30 only needs to be directly installed on the connecting component, which can ensure the precise assembly of the display module 30 on the mounting surface 20. There is no need to precisely adjust the relative position of the display module 30 and the mounting surface 20, which can greatly save manpower and working hours.

[0040] The mounting plate 10 is provided with a plurality of light-transmitting holes 18 penetrating the front side 11 and the back side 12 thereof. When a plurality of light-transmitting holes 18 are provided, the shapes and sizes of the light-transmitting holes 18 are consistent, and the lamp beads of the display module 30 are located in the light-transmitting holes 18. The provision of the light-transmitting holes 18 enables the lamp beads of the display module 30 that overlap with the mounting plate 10 to still participate in the picture display, so as to prevent the mounting plate 10 itself from blocking the lamp beads of the display module 30, thereby causing the display picture to be partially dimmed.

[0041] Specifically, the connection component includes a connection hole 131 opened on the back side 12 of the mounting plate 10. The connection hole 131 may be a blind hole or a through hole. In this embodiment, the display module 30 is provided with a mounting through hole, and a self-tapping screw may pass through the mounting through hole and be screwed to the connection hole 131 to connect the display module 30 and the connection hole 131. When the display module 30 needs to be maintained, the display module 30 and the connection hole 131 can be separated by loosening the self-tapping screw, so as to disassemble the display module 30.

[0042] Of course, multiple mounting plates 10 can be arranged on the mounting surface 20, and two adjacent mounting plates 10 can be connected end to end or arranged parallel to each other. Each mounting plate 10 is provided with multiple connecting holes 131 to connect multiple different mounting through holes on the display module 30, and multiple different display modules 30 can also be connected to the same mounting plate 10 through their respective mounting through holes.

[0043] Example 2

[0044] Combination Figures 1 to 7 , Fig.10 As shown, the difference between this embodiment and the first embodiment is that the connecting component includes a first positioning column 13 provided on the back side 12 of the mounting plate 10, and a connecting hole 131 is provided on the end face of the first positioning column 13. The end face of the first positioning column 13 protrudes from the back side 12 of the mounting plate 10, and a positioning cavity is provided on the display module 30, and the above-mentioned mounting through hole is provided in the positioning cavity. When the display module 30 is installed on the mounting plate 10, the end of the first positioning column 13 is embedded in the positioning cavity to achieve rapid positioning between the display module 30 and the mounting plate 10. The inner wall of the connecting hole 131 is provided with an internal thread, and existing screws or bolts can be used to pass through the mounting through hole of the display module 30 and the connecting hole 131 on the first positioning column 13 to fasten the display module 30 and the mounting plate 10. The first positioning column 13 is preferably a copper nut embedded in the back side 12 of the mounting plate 10, which has both positioning function and threaded connection function.

[0045] like Figures 1 to 4, the edge of the mounting plate 10 is provided with a positioning protrusion 15 and / or a positioning notch 16, and the shapes of the positioning protrusion 15 and the positioning notch 16 match. In this embodiment, one end face of the mounting plate 10 is provided with a positioning protrusion 15 and two positioning notches 16, wherein the two positioning notches 16 are respectively located on both sides of the positioning protrusion 15; the other end face of the mounting plate 10 is provided with two positioning protrusions 15 and a positioning notch 16, wherein the two positioning protrusions 15 are respectively located on both sides of the positioning notch 16. When there are two mounting plates 10, the positioning protrusion 15 of one mounting plate 10 is embedded in the positioning notch 16 of the other mounting plate 10. The provision of the positioning notch 16 and the positioning protrusion 15 facilitates the alignment of the two mounting plates 10 for mutual splicing, so that the end faces of multiple mounting plates 10 can be connected end to end.

[0046] Furthermore, the back side 12 of the mounting plate 10 is provided with a second positioning column 14 located at its edge, and one side of the second positioning column 14 has a positioning protrusion 15. The second positioning column 14 is used to cooperate with the positioning notch 16 of another mounting plate 10 to guide the two mounting plates 10 to align and splice with each other.

[0047] In addition, if Figure 7 The aperture of the light-transmitting hole 18 on the front side 11 of the mounting plate 10 is larger than the aperture of the light-transmitting hole 18 on the back side 12 of the mounting plate 10. Therefore, the small end of the light-transmitting hole 18 faces the lamp bead of the display module 30, and the large end of the light-transmitting hole 18 faces the mounting surface 20. The structure of the light-transmitting hole 18 can avoid blocking the light emitted by the lamp bead on the display module 30. In the present embodiment, the aperture of the light-transmitting hole 18 is circular, and the light-transmitting hole 18 has a conical surface 181. The angle between the generatrix of the conical surface 181 and the axis of the light-transmitting hole 18 is 60°.

[0048] Example 3

[0049] Combination Figure 8 and Fig. 9 As shown, the difference between this embodiment and embodiment 2 is that the opening of the light-transmitting hole 18 is polygonal, the inner wall of the light-transmitting hole 18 has an inclined surface, and the angle between the inclined surface and the axis of the light-transmitting hole 18 is 60°.

[0050] Example 4

[0051] In order to solve the same technical problem, the utility model also provides a display device, including a display module 30, a transparent panel and the mounting structure as described above, wherein the display module includes a substrate and a plurality of light-emitting units arranged on the surface of the substrate, the light-emitting units can be LED lamp beads or LED light-emitting chips, the substrate is detachably connected to the back side 12 of the mounting plate 10, and the front side 11 of the mounting plate 10 is adhered to the panel through an adhesive layer 17, wherein the light-emitting unit is located in the light-transmitting hole, and the light emitted by the light-emitting unit can pass through the light-transmitting hole.

[0052] To summarize, the front side 11 of the mounting plate 10 is used to fit onto the mounting surface 20, and the back side 12 is provided with a connecting component that can be detachably connected to the display module 30, so that the display module 30 can be conveniently and quickly removed from the mounting plate 10, thereby improving the installation and maintenance efficiency of the display module 30. Since the position of the connecting component on the mounting plate 10 is relatively fixed, when multiple display modules 30 are installed on the same mounting plate 10, it can be ensured that two adjacent display modules 30 remain aligned to avoid the appearance of bright and dark lines. The mounting plate 10 itself is light-transmitting, and is provided with a light-transmitting hole 18 that passes through the front side 11 and the back side 12. The light-transmitting hole 18 allows light emitted by the lamp beads on the display module 30 to pass through the mounting plate 10, so that the lamp beads of the part where the display module 30 is connected to the mounting plate 10 can also participate in the picture display.
