Existing display panels and display brackets are usually fixed by welding, and the display brackets need to be reflowed and welded together with the display panels to connect to the display control board. However, display brackets are mostly made of plastic, which is prone to deformation during high-temperature welding, leading to disengagement of the fasteners or positioning deviations, which in turn causes problems such as display ghosting and poor contact. Moreover, the integrated welded display panel and display bracket are not easy to maintain later, and the whole assembly needs to be disassembled for repair, which is costly.

[0003] It is clear that there is room for improvement in the existing technology. Utility Model Content

[0034] The following is combined with Figures 1 to 4 The embodiments of this utility model are described below.

[0035] One installation structure in this embodiment includes:

[0036] Display panel 1 has bracket mounting holes 11 and snap holes 12, with the snap holes 12 penetrating the display panel 1;

[0037] The display bracket 2 has a positioning post 21 and an elastic arm 22. One end of the positioning post 21 is fixedly connected to the mounting surface of the display bracket 2, and the other end of the positioning post 21 is inserted into the bracket mounting hole 11. One end of the elastic arm 22 is fixedly connected to the display bracket 2, and the other end of the elastic arm 22 is provided with a barb 23. The end of the elastic arm 22 with the barb 23 passes through the locking hole 12, so that the barb 23 is locked onto the edge of the locking hole 12.

[0038] In this embodiment, the surface of the display panel 1 is integrated with circuit components, and it is also provided with two types of hole structures, namely bracket mounting hole 11 and card hole 12.

[0039] The bracket mounting hole 11 is used to insert the positioning post 21 set in the display bracket 2. The diameter of the positioning post 21 is slightly smaller than the diameter of the bracket mounting hole 11, so that the positioning post 21 can be inserted into the bracket mounting hole 11. The positioning post 21 and the bracket mounting hole 11 form a clearance fit to limit the horizontal displacement of the display bracket 2 and the display panel 1.

[0040] The locking hole 12 is a through hole that passes through the display panel 1. It is used to engage with the barb 23 at the end of the elastic arm 22. The elastic arm 22 is a cantilever structure. One end of it is fixed to the display bracket 2, and the other end is provided with the barb 23. After the end of the elastic arm 22 with the barb 23 is inserted into the locking hole 12, the barb 23 engages with the edge of the buckle, thereby fixing the display panel 1 and the display bracket 2.

[0041] The installation process of display panel 1 and display bracket 2 is as follows: Align the positioning post 21 of display bracket 2 with the bracket mounting hole 11 of display panel 1, press the display bracket 2 lightly, and the positioning post 21 will be inserted into the hole to initially determine the planar position of display bracket 2 on display panel 1; continue to press the display bracket 2, and the elastic arm 22 will bend elastically as the bracket descends. After the end barb 23 passes through the locking hole 12, the elastic arm 22 will return to its original position due to the elasticity of the material, and the barb 23 will lock the edge of the locking hole 12 to form a vertical locking connection, preventing the display bracket 2 from detaching from display panel 1;

[0042] The disassembly process of display panel 1 and display bracket 2 is as follows: Press the free end of elastic arm 22 to make it bend and deform. The barb 23 moves with elastic arm 22 and disengages from the edge of the locking hole 12. At this time, the display bracket 2 can be lifted directly, and the positioning post 21 is pulled out from the bracket mounting hole 11, completing the separation of the two.

[0043] In traditional solutions, the display bracket 2 and the display panel 1 are fixed by welding. The bracket needs to be reflowed with the display panel 1 for welding. High temperatures cause the plastic bracket to deform and the fasteners to fail. Furthermore, it is difficult to disassemble after welding. This utility model uses the positioning post 21 inserted into the bracket mounting hole 11 to limit the displacement of the display panel 1 and the display bracket 2, ensuring the accurate relative position of the display bracket 2 and the display panel 1. Then, the elastic arm 22 and the barb 23 are engaged with the edge of the locking hole 12 to form a stable weld-free mechanical positioning structure. At the same time, the elastic deformation characteristics of the elastic arm 22 allow the display bracket 2 to be quickly disassembled and installed by pressing.

[0044] Specifically, the display panel 1 is provided with a plurality of spring-loaded touch keys 13, and the display bracket 2 is provided with touch key limiting frames 24 corresponding to the spring-loaded touch keys 13; each touch key limiting frame 24 surrounds the outer periphery of the spring-loaded touch key 13 and forms a limiting space to restrict the lateral displacement of the spring-loaded touch key 13.

[0045] Multiple spring-loaded buttons 13 are welded to the surface of the display panel 1 to transmit electrical signals for user pressing operations. On the display bracket 2, corresponding to the position of each spring-loaded button 13, a touch limit frame 24 is provided on the side facing the display panel 1. The touch limit frame 24 surrounds the outer periphery of the spring-loaded button 13 and forms a limiting space to restrict the lateral displacement of the spring-loaded button 13 and strictly limit the movement trajectory of the spring-loaded button 13 to the vertical direction, so as to avoid accidental touch or poor contact of adjacent spring-loaded buttons 13 due to lateral displacement. In addition, traditional solutions require additional complex structures such as metal guide sleeves to limit the touch displacement, while this design achieves the same function through the touch limit frame 24 integrally formed by the display bracket 2, reducing the number of parts.

[0046] Specifically, the touch limit frame 24 is provided with a touch observation hole 25, which is located above the spring touch 13.

[0047] At the top center of each key limit frame 24, there is a through key observation hole 25; the installation status of the spring key 13 can be directly observed through the observation hole. If a key fails during equipment operation, it can be quickly determined whether the key has been displaced or damaged through the observation hole without disassembling the display bracket 2.

[0048] Specifically, the display panel 1 is provided with an indicator light 14 and a receiver 15, and the display bracket 2 is provided with an indicator light hole 26 and a signal receiving window 27; the indicator light hole 26 is located above the indicator light 14, and the signal receiving window 27 is located above the signal receiver 15.

[0049] Specifically, the inner walls of the lamp hole 26 and the signal receiving window 27 are inclined from the inside out.

[0050] Display panel 1 has integrated indicator lights 14 on its surface for emitting indicator light;

[0051] On the display bracket 2, a lamp hole 26 is provided corresponding to the position of the display lamp 14. The lamp hole 26 is a through hole, and its axis is aligned with the light-emitting center of the display lamp 14. The inner wall is inclined from the inside to the outside, forming a funnel-shaped structure.

[0052] Similarly, the display panel 1 is also equipped with a receiver 15 for receiving external control signals; and the display bracket 2 is equipped with a signal receiving window 27, which is also a through hole, with its opening facing the photosensitive surface of the signal receiver 15, and its inner wall also sloping from the inside to the outside.

[0053] The inclined inner walls of the signal receiving window 27 and the lamp hole 26 expand the receiving angle, forming a design similar to a lampshade, which can effectively conduct signals to make the display clearer and the signal reception more stable.

[0054] Specifically, the installation structure also includes a control box 3, which has an internal mounting groove that opens toward its rear end; the display bracket 2 is disposed in the mounting groove; and the front end of the control box 3 has a window 31 corresponding to the position of the lamp hole 26, the signal receiving window 27 and the spring touch button 13.

[0055] Specifically, the mounting structure also includes a display appearance diaphragm 4; the display appearance diaphragm 4 is disposed on the front end face of the control box 3.

[0056] Specifically, the mounting structure also includes a cover plate 5; the cover plate 5 is connected to the rear end face of the control box 3; the cover plate 5 and the control box 3 form a sealed space to accommodate the display panel 1 and the display bracket 2.

[0057] In this embodiment, the control box 3 is an open box with five sides enclosed. The display bracket 2 can be fixed to the inside of the control box 3 by bolts, clips or adhesive. The front side of the control box 3 has a window 31, which corresponds to the position of the display light 14, the signal receiving window 27 and the spring touch key 13 to form a human-machine interaction area. The rear side of the control box 3 is provided with screw holes or clip slots.

[0058] The cover plate 5 is a flat plate structure that matches the rear end face of the control box 3. The edge is provided with through holes corresponding to the screw holes of the control box 3, or elastic buckles that cooperate with the buckle slots. The cover plate 5 is tightly connected to the rear end face of the control box 3 by screws or buckles.

[0059] The display diaphragm 4 can be made of transparent material with printed patterns on the surface. The diaphragm is attached to the front face of the control box 3 by pasting or snapping, and the window 31 of the control box 3 in the light-transmitting area is fully aligned.

[0060] The assembled display panel 1 and display bracket 2 are installed into the inside of the control box 3, and the display panel 1 and display bracket 2 are fixed by screws or latches on the inner wall of the control box 3; then the cover plate 5 is connected to the rear end face of the control box 3 to cover the rear end face of the control box 3, forming a closed sealed space, thus completing the assembly.

[0061] Specifically, the display panel 1 is provided with a positioning hole 16, and the display bracket 2 is provided with a support column 28; one end of the support column 28 is fixedly connected to the display bracket 2, and the other end of the support column 28 passes through the positioning hole 16.

[0062] In this embodiment, the display panel 1 has a positioning hole 16 in the central area of ​​its surface, and the display bracket 2 has a support column 28 at the position corresponding to the positioning hole 16; the support column 28 is a columnar structure, one end of which is fixedly connected to the bottom surface of the bracket, and the other end is a free end;

[0063] Since the display bracket 2 is only connected to the display panel 1 through the positioning post 21 and the elastic arm 22 on the edge, the middle area is suspended. When it is pressed or vibrated, the display bracket 2 is prone to bending and deformation. Therefore, the display bracket 2 is provided with a positioning post 21 to connect with the positioning hole 16 on the display panel 1, so as to provide support for the display bracket 2 and reduce the deformation caused by the middle being suspended.

[0064] A second aspect of this utility model provides an indoor air conditioning unit, including the installation structure described in the above embodiments.
