[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.
[0050] Example 1:
[0051] Please see Figures 1-8 A light-emitting panel includes: four light guides 1, which are spliced together to form a rectangular structure; a back shell 4, on which the four light guides 1 are mounted; a touch PCBA 2, which is disposed in the cavity formed by the light guides 1 and the back shell 4; a control PCBA 3, which is disposed in the cavity formed by the light guides 1 and the back shell 4, and is located between the back shell 4 and the touch PCBA 2, wherein both the touch PCBA 2 and the control PCBA 3 are provided with BTC connectors 7, and the two sets of BTC connectors 7 are interlocked; and an elastic clip 8, through which the light guides 1 and the back shell 4 are detachably connected.
[0052] By adopting the above technical solution, the touch PCBA2 can be touched by touching the light guide 1 during use, thereby completing the use.
[0053] Each light guide 1 includes: a light guide plate 11, which is a stepped structure, and the rectangular structure formed by the four light guide plates 11 has a first accommodating space 12 and a second accommodating space 13, and the area of the second accommodating space 13 is smaller than that of the first accommodating space 12; a positioning boss 15 is also installed on the light guide plate 11.
[0054] The touch PCBA2 includes: a touch panel 21, the shape of which is adapted to the second accommodating space 13, and has a slot 22 and a light-transmitting hole 26. The touch panel 21 is also equipped with a screen interface 25, and a positioning boss 15 is inserted into the slot 22; a light-emitting element 23, which is disposed on the touch panel 21 and located at the light-transmitting hole 26; and four solder-laying sensing areas 24, which are disposed on the touch panel 21 and located on the side facing the light guide plate 11.
[0055] The rear shell 4 includes: an outer shell 41, one end of which contacts the first accommodating space 12 of the light guide plate 11, and a protrusion 42 and a buckle 43 are fixedly installed on its concave surface; the control PCBA3 is snapped between the protrusion 42 and the buckle 43.
[0056] By adopting the above technical solution, when in use, touching the light guide plate 11 causes the light guide plate 11 to apply pressure to the tin-insulating sensing area 24, thereby completing the use. At the same time, the light-emitting element 23 emits light through the light-transmitting hole 26 and then through the light guide plate 11 to provide a lighting effect.
[0057] The four light guide plates 11 are equivalent to four touch buttons, which can realize three interaction methods: short press, long press, and double press through user interaction. For example, in the KNX system, the light-emitting panel can be configured with the corresponding program through ETS software to realize the three interaction methods of short press, long press, and double press to achieve multiple functions, including but not limited to the control of ambient lights, curtains, air conditioning, floor heating, fresh air, scenes, etc. Specifically, the light emission form, color, color temperature, brightness, time, etc. of the light-emitting element 23 can also be controlled to realize the function of the panel as a night light or a light-emitting decorative element.
[0058] Each light guide plate 11 has slots 16 on two mutually perpendicular sides; the outer casing 41 is also provided with elastic clips 8; the elastic clips 8 include: guide rods 81, which are provided in two sets and are perpendicular to each other, and are fixedly installed inside the bottom surface of the outer casing 41; movable rods 82, which are provided in two sets and are respectively movably sleeved on the two sets of guide rods 81, and the ends of the movable rods 81 extend out of the guide rods 81. The guide rods 81 are also provided with springs 83, and the two ends are respectively fixed to the outer casing 41 and the movable rods 82; driving gear 84 and driven gear 85, which mesh with each other, and the driving gear 84 and driven gear 85 are respectively meshed with the two sets of movable rods 82. The driving gear 84 and driven gear 85 are rotatably connected to the outer casing 41; guide wheel 86, which is located outside the outer casing 41 and is fixed to the driving gear 84. The outer end of the movable rod 82 also has a beveled surface 87.
[0059] In this embodiment, the above-described method is adopted, making the light guide plate 11 and the housing 41 easy to disassemble and install. Specifically, by rotating the guide wheel 86, the driving gear 84 drives the driven gear 85 to rotate, thereby causing the two movable rods 82 to move. This allows the movable rods 82 to be controlled to insert into or leave the slot 16, thus completing the installation and disassembly. This facilitates cleaning, component replacement, maintenance, and other operations within the panel, achieving a user-friendly effect.
[0060] Example 2:
[0061] Based on embodiment 1, the rectangular structure formed by the four light guide plates 11 also has a third accommodating space 14 with an area smaller than the second accommodating space 13; a display screen 5 adapted to the third accommodating space 14 is also provided between the light guide plate 11 and the touch PCBA2, and is electrically connected to the screen interface 25, thereby providing the effect of data display.
[0062] Example 3:
[0063] Based on Embodiment 1 or Embodiment 2, the touch panel 21 is also provided with a temperature and humidity sensor 6 for collecting ambient temperature, so that the panel can be used as a temperature control panel.
[0064] Working principle: During disassembly, rotating the guide wheel 86 causes the drive gear 84 to drive the driven gear 85 to rotate, thereby moving the two movable rods 82. This allows the movable rods 82 to be controlled to leave the slot 16, thus completing the disassembly. This facilitates cleaning, replacement of parts, and maintenance of the panel. During installation, simply align the light guide plate 11 with the housing 41 so that the light guide plate 11 contacts the beveled surface 87, and press the movable rod 82 into the housing 41 until the light guide plate 11 and the housing 41 are in close contact. Then, under the action of the spring 83, the movable rod 82 is inserted into the slot 16.
