Description

Technical Field

[0001] The utility model relates to the technical field of keyboards, in particular to a backlight module of a luminous keyboard. Background Art

[0002] As an important component of a computer, a keyboard is installed with a light-emitting component inside the keyboard for use in dark or no light conditions, so that the keys on the keyboard can be seen through these light-emitting components. After searching, the Chinese patent authorization number CN213781888U discloses a backlight module for a light-emitting keyboard, a keyboard body, a waterproof layer is arranged on one side of the keyboard body, a light guide plate is arranged on the side of the waterproof layer away from the keyboard body, a reflective layer is arranged on the side of the light guide plate away from the keyboard body, a light source plate is arranged on one side of the light guide plate, and a reflective surface is arranged on the side of the light guide plate away from the keyboard body; the backlight module for the light-emitting keyboard is provided with a waterproof layer, a light guide plate, a reflective layer, a light source plate and keyboard keys, and the waterproof layer is provided to cooperate with the keyboard for waterproofing, which can solve the problem of uniformity of visual effects of the existing keyboard backlight module, making the visual effect of the entire keyboard characters more uniform, and because each key is in a surface luminous state, the light-emitting module can be used for keyboards of various structures, and its versatility is stronger, and similarly due to the surface luminous state, the light leakage and halo around the keys are more uniform. However, when the keyboard is left unused for a long time, a large amount of dust will accumulate on the surface of the keyboard and inside the keys. When cleaning the dust, the keys can be taken out for cleaning. However, since there are light-emitting components inside the pressing parts of the keys, the dust will enter the interior of the keyboard through these keys. After long-term use, it will cause internal failure of the keys. In addition, since there is a large gap between the keys and the pressing device below, when the surface of the keyboard is cleaned without removing the keys, the cleaning device can easily scrape down the pressing device of the keyboard, causing damage to the pressing device during long-term use and making it inconvenient to clean. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a backlight module for an luminous keyboard, which solves the problem that a large amount of dust will accumulate on the surface of the keyboard and inside the keys when the keyboard is left unused for a long time. When cleaning the dust, the keys can be taken out for cleaning. However, since there are luminous components inside the pressing parts of the keys, the dust will enter the interior of the keyboard through the keys, which will cause internal failure of the keys after long-term use. In addition, since there is a large gap between the keys and the pressing device below, when the surface of the keyboard is cleaned without removing the keys, the cleaning device is likely to scrape down the pressing device of the keyboard, causing the pressing device to be damaged during long-term use and making it inconvenient to clean.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions: a backlight module of an illuminating keyboard, including a keyboard and a key, the interior of the keyboard has a plurality of reflective seats fixedly installed at equal intervals, the interior of the reflective seats are each installed with a light-emitting lamp, and the light-emitting part of the light-emitting lamp is on the top surface of the reflective seat, the interior of the top surface of the keyboard is provided with a plurality of connecting grooves at equal intervals, the reflective seats are each arranged in the connecting groove, the key is sleeved on the reflective seat, the bottom of the key is connected to the interior of the connecting groove, and the outer side wall of the key is slidably connected to the side wall of the connecting groove.

[0005] Preferably, a pressing part is installed inside the reflective seat, a connecting column is provided inside the button, and a support rod is symmetrically fixedly installed on the side wall of the connecting column. The support rod is L-shaped, and both ends of the support rod are fixedly connected to the inner side wall of the button, so as to support the pressing component inside the button.

[0006] Preferably, the top surface of the connecting column does not contact the top surface inside the key, so that the internal light source of the key can be sufficient.

[0007] Preferably, a display groove is provided inside the side wall of the top surface of the button, and a reflective film is tightly attached to the inside of the button, so that the light of the reflective film can be seen through the display groove.

[0008] The utility model provides a backlight module for a light-emitting keyboard, which has the following beneficial effects:

[0009] 1. When the backlight module of the luminous keyboard is used, the bottom of the key is connected to the inside of the connecting groove after the key is installed by the cooperation between the connecting groove and the key, so as to prevent dust from entering the inside of the keyboard;

[0010] 2. When the backlight module of the luminous keyboard is used, the bottom of the key is connected to the inside of the connecting groove, so that the pressing device is completely inside the key, so that the key can protect the pressing device. Even if the key is not removed, when the surface of the keyboard is cleaned, the cleaning device will not scrape down the pressing device and the luminous device. BRIEF DESCRIPTION OF THE DRAWINGS
