Technical Field
[0001] This utility model belongs to the field of keyboard technology, specifically relating to a novel illuminated keyboard and backlight module. Background Technology
[0002] An illuminated keyboard is a keyboard whose keys can emit light, usually through built-in LEDs. These keyboards have different lighting effects on the key areas, and the color and brightness can be adjusted through settings. In a keyboard, the backlight module usually consists of a series of LEDs. The light shines onto the keys through transparent or semi-transparent keycaps to create a bright effect. The main function of the backlight module is to provide illumination, especially in low-light environments, so that users can see the keys on the keyboard clearly in the dark.
[0003] Chinese patent disclosure (authorization announcement number CN222260864U) discloses a backlight module for an illuminated keyboard. This patented technology solves the problem that when a keyboard is left unused for a long time, a large amount of dust accumulates on the surface of the keyboard and inside the keys. While cleaning the dust involves removing the keys for cleaning, the dust can still enter the keyboard through the keys because the key press areas contain light-emitting components. Over time, this can cause the keys to malfunction. The keyboard has multiple reflector mounts fixedly installed at equal intervals inside, each containing a light-emitting lamp. The light-emitting part of the lamp is located on the top surface of the reflector mount. Through a connecting groove that cooperates with the keys, the bottom of the keys is connected to the inside of the connecting groove after installation, preventing dust from entering the keyboard.
[0004] However, most existing keyboards are assembled using screws, which results in poor heat dissipation. Over time, the accumulated heat can become too high and cause damage. For example, the aforementioned prior art uses screws to assemble the keyboard. Therefore, those skilled in the art have proposed a novel illuminated keyboard and backlight module to address the problems described in the background section. Utility Model Content

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0025] like Figures 1-3 As shown, a novel illuminated keyboard and backlight module includes a keyboard 1, a cover plate 5 disposed below the keyboard 1, a circuit board 6 disposed inside the cover plate 5, and keys 11 symmetrically disposed on the upper surface of the keyboard 1. A positioning groove 31 is provided on the upper surface of the keyboard 1, and a reflector 3 is installed inside the positioning groove 31. A pressing member 34 is provided at the middle position of the upper surface of the reflector 3, and an LED 32 is provided on the upper surface of the reflector 3 outside the pressing member 34. This arrangement can achieve the purpose of illuminating the keyboard 1 by using the LED 32 on the reflector 3.
[0026] The keyboard 1 and the cover plate 5 are provided with a protective plate 4, and the protective plate 4 is provided with a protective pad 41. This arrangement uses the protective plate 4 and the protective pad 41 to protect the keyboard 1 and the cover plate 5.
[0027] The keyboard 1 has symmetrical ventilation holes 2 on its upper surface, and a filter 21 is provided inside the keyboard 1 below the ventilation holes 2. Mounting plates 22 are symmetrically arranged on both sides of the filter 21. This arrangement uses the ventilation holes 2 to allow the circuit board 6 inside the keyboard 1 to dissipate heat.
[0028] like Figure 1 As shown, a sealing gasket 33 is also provided on the inner side of the positioning groove 31. The outer side of the button 11 contacts the inner side of the sealing gasket 33.

The protective pad 41 is made of rubber. The height of the protective plate 4 is the same as the height of the protective pad 41. This arrangement uses one end of the bolt 42 to be threadedly connected to the mounting hole 12, so that the protective plate 4 can be installed on the outside of the keyboard 1 and the cover plate 5 to protect the outside of the keyboard 1 and the cover plate 5.
[0030] like Figure 3 As shown, the lower surface of the keyboard 1 has a mounting groove for mounting the mounting plate 22. The mounting plate 22 is installed inside the mounting groove by bolts. The filter screen 21 is a stainless steel mesh. The heat dissipation holes 2 are round holes on the upper surface of the keyboard 1. This setting can achieve the purpose of ventilation and heat dissipation inside the keyboard 1 by opening the heat dissipation holes 2. At the same time, the filter screen 21 can prevent external dust from entering the keyboard 1 and damaging the circuit board 6.
[0031] The working principle of this utility model is as follows: When the luminous keyboard and backlight module of this utility model are in use, the positioning groove 31 opened on the upper surface of the keyboard 1 is provided with a reflector 3 and a light lamp 32, so that it can emit light when in use to improve its aesthetics. In addition, the inner side of the positioning groove 31 is provided with a sealing gasket 33 to seal it and prevent external dust from entering and affecting its use.
[0032] A protective plate 4 is provided on the outside of the keyboard 1 and the cover plate 5. By rotating multiple bolts 42, one end of the plate can be threadedly connected to the mounting hole 12 on the outside of the keyboard 1 and the cover plate 5. In this way, the keyboard 1 and the cover plate 5 can be connected through the protective plate 4. At the same time, a protective pad 41 is also provided on the outside of the protective plate 4 to protect the outside of the keyboard 1 and the cover plate 5.
[0033] The keyboard 1 has symmetrical heat dissipation holes 2, which can dissipate heat from inside the keyboard 1 and intercept external dust through the filter screen 21. This can prevent external dust from entering the keyboard 1 and damaging the circuit board 6. The structure is simple, easy to install and disassemble, and has good practicality.
