[0023] Example: Please refer to Figures 1-4 In this embodiment of the invention, a light-emitting module includes a card holder 2, on which guide posts 3 are symmetrically fixed. An installation cylinder 4 is slidably sleeved on the outside of the guide post 3 along its axial direction. When the installation cylinder 4 slides to the top part of the guide post 3, a locking head 8 cooperates with the guide post 3 to lock and position the installation cylinder 4. A light-emitting plate 5 is fixed between the two installation cylinders 4.

[0024] In other words, in this embodiment, the light-emitting part of the light-emitting module includes the light-emitting board 5, while the mounting part includes the card holder 2. In fact, the size of the card holder 2 can be customized in advance, so as to facilitate the subsequent card holder to be attached to the outside of the corresponding keyboard.

[0025] In practice, the height of the light-emitting panel 5 can be adjusted according to the actual situation. For example, when using the keyboard, the light-emitting panel 5 is raised, and when not using the keyboard, the light-emitting panel 5 is lowered.

[0026] More specifically, the backlighting module can provide daily protection for the keyboard, such as preventing dust from entering between the keys. In addition, the backlighting module is a modular product that can be installed on existing keyboards, offering high flexibility.

[0027] The card holder 2 is a C-shaped structure with two sides and a front. Its opening is symmetrically fixed with a card shoulder. The C-shaped structure and the card shoulder can be used to lock the card holder 2 onto the keyboard. The card shoulder is used to install the guide post 3.

[0028] In this embodiment, as Figure 3 The light-emitting plate 5 includes a mounting plate 51, on which a plurality of key slots are provided. A key plate 52 is embedded in the key slots. The key plate 52 is made of transparent material. A shielding plate 54 is fixed on three sides of the key plate 52, and a light lamp 53 is fixed on the other side. The light lamp 53 is controlled by a control board, which is embedded in the card holder 2.

[0029] The control board is a common PCB board, which will not be described in detail here. The control board can be electrically connected to a computer via USB serial port and controlled by the computer.

[0030] In a preferred embodiment, a camera is fixed below the mounting plate 51, the camera is electrically connected to the control board, and the camera is positioned away from the keypad 52.

[0031] It should be explained that currently, many beginners or people who are not proficient in using the keyboard often need to look down at the keyboard to assist in typing. However, in this embodiment, by setting up a camera to capture the keyboard and display it on the computer, it is possible to assist in typing by looking directly at the screen without looking down at the keyboard.

[0032] The camera can be a miniature camera;

[0033] The number of cameras can be two;

[0034] To ensure effective protection of the keyboard under normal conditions, two side folding films and one rear folding film are fixedly connected between the mounting plate 51 and the card holder 2. The two side folding films and the rear folding film together form a C-shape. Furthermore, the card holder 2 is a C-shaped structure with two sides and a front, and its opening is symmetrically fixed with shoulders for mounting the guide posts 3. The sides of the card holder 2 are hollow structures with holes on the upper surface of the cavities, and a heater and a fan are installed in the cavities.

[0035] It needs to be explained that, on the one hand, the two side folds and one rear fold can prevent dust from entering the gaps between the keys on the keyboard. On the other hand, it can also guide the airflow from the fan, allowing the air to pass through the user's hands. This solves the problem of typing with sweaty hands in summer and typing with gloves in winter, thus improving the comfort of using the keyboard.

[0036] In this embodiment, as Figure 4 The guide post 3 includes a post body 31, the top of the post body 31 is provided with a groove 32 for accommodating the locking head 8, and the side of the groove 32 is provided with a plurality of mounting grooves 33, in which a locking arc member 34 is embedded.

[0037] The locking head 8 includes a screwing member 81, and a plug 82 is fixed to the bottom of the screwing member 81. The plug 82 is slidably connected to the groove 32 in a sealed manner.

[0038] The locking arc component is an elastic component;

[0039] During implementation, the mounting cylinder 4 is first moved upward to correspond with the locking arc 34, and then the driving plug is moved downward, so that the gas inside the groove is pressurized and pushed to the position of the locking arc, thereby driving the locking arc to deform and lock the mounting cylinder. In addition, the upper part of the screw 81 has an external thread and the opening of the groove has an internal thread, which ensures the stability of the locking limit.

[0040] In a preferred embodiment, an annular damping pad 9 is embedded in the inner wall of the mounting cylinder 4.

[0041] In a preferred embodiment, a locking ball 35 is also included, the locking ball 35 having an oblong hole 36, a shaft being fixed in the mounting groove 33, the shaft being sleeved in the oblong hole 36 of the locking ball 35, and an inverted frustum 83 being fixed to the bottom of the plug 82.

[0042] In practice, the locking ball 35 can be driven by the frustum to press against the locking arc, thereby driving the locking arc to deform and lock the mounting cylinder. Furthermore, the upper part of the screw 81 has an external thread, and the opening of the groove has an internal thread, which ensures the stability of the locking limit.

[0043] A backlit keyboard includes a keyboard 1 on which a backlight module is mounted.

[0044] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
