Detailed implementation mode

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] Refer to Figures 1-4 , a backlit keyboard with a color recognition sensor, including a keyboard upper cover 3, a color recognition module 5, a PCBA main board 7 and a keyboard lower cover 9; wherein the keyboard upper cover 3 and the keyboard lower cover 9 are covered (attached by screws) to form a receiving space, the color recognition module 5 and the PCBA main board 7 are placed in the receiving space, a backlight module is integrated on the PCBA main board 7, the color recognition module 5 is electrically connected to the PCBA main board 7, the color recognition module 5 recognizes the color of an item and converts it into a digital signal, and the PCBA main board 7 controls the backlight module to the corresponding color according to the received digital signal. By adding the color recognition module 5 to the keyboard, when the user uses it, they only need to place an item of their favorite color in front of the recognition position of the color recognition module 5 for a few seconds. The color recognition module 5 will recognize the color of the item, and after recognition, it will automatically set the color of the backlight module to be the same as it, which can make the keyboard backlight more coordinated with the colors of surrounding items or devices, and greatly improve the visual and experience effects of players.

[0022] The specific principle is that the color recognition module 5 recognizes the color of the corresponding item and converts it into a digital signal to the PCBA main board 7. After receiving this data, the PCBA main board 7 will control the I0 port to change the PWM signal and automatically set the backlight module to the same color as this item.

[0023] Further, the color recognition module 5 includes an upper cover 52, an LED light source 53, a photodetector 54, a second PCBA main board 56, and a bottom cover 57. The upper cover 52 and the bottom cover 57 are covered to form an accommodation space. The LED light source 53, the photodetector 54, and the second PCBA main board 56 are all placed in the accommodation space. A through hole for the photodetector 54 to be embedded is provided at the center of the top of the upper cover 52. There are multiple LED light sources 53 which are circumferentially distributed around the photodetector 54. Hole positions for the LED light sources 53 to be embedded are also provided at the top of the upper cover 52. The photodetector 54 is electrically connected to the second PCBA main board 56. The second PCBA main board 56 is electrically connected to the PCBA main board 7 through an FPC cable. A filter 55 is also provided on the photodetector 54. The original (white) light source can be emitted to an object through the LED light source 53 to provide a clear picture for the photodetector 54. Then, the color information of the object to be measured and its detection environment is obtained by the photodetector 54, and the optical signal is converted into an electrical signal. Then, the corresponding signal is transmitted into the second PCBA main board 56, and these electrical signals are analyzed by the second PCBA main board 56 to determine the color of the object.

[0024] It should be mentioned that color recognition technology is already a well-known existing technology and will not be elaborated specifically here.

[0025] Further, the color recognition module 5 further includes a rotating shaft 51. The upper cover 52 is provided with mounting holes for the rotating shaft 51 to pass through and be fixed along the horizontal direction. A slot 31 for the color recognition module 5 to protrude is provided on the upper cover 3 of the keyboard. Both ends of the rotating shaft 51 are rotatably arranged in the shaft holes reserved on both sides of the slot 31. When the color recognition module 5 is used, the upper cover 52 can be correspondingly pressed. Under the action of the rotating shaft 51, the color recognition module 5 can be driven to rotate until the color recognition module 5 is adjusted to the recognition position (refer to Figure 2 shown). After the recognition is completed, the color recognition module 5 can be toggled to the horizontal position without interfering with the normal use of the subsequent keyboard. Additionally, an elastic gasket (not shown in the figure) can be sleeved on the rotating shaft 51 to increase the damping between the color recognition module 5 and the upper cover 52 to ensure the stability after the position adjustment.

[0026] Among them, the slot 31 is designed in the blank area (i.e., the area without keys) of the upper cover 52, which can realize color recognition without interfering with the normal use of the keyboard.

[0027] Further, the backlight module includes multiple RGB LED lights 6. The multiple RGB LED lights 6 are arranged and distributed on the upper surface of the PCBA main board 7. The RGB LED lights 6 have the function of color change, so that the corresponding color adjustment operation can be realized according to the control instructions of the PCBA main board 7.

[0028] Further, it further includes a plurality of patch buttons 4 which are arranged and distributed on the upper surface of the PCBA main board 7 and are in one-to-one correspondence with the plurality of RGB LED lights 6. A keycap 1 is correspondingly arranged at the top of the patch button 4, and the keyboard upper cover 3 is correspondingly provided with keyholes for the keycap 1 to protrude.

[0029] Further, a reinforcing plate 8 is also arranged between the PCBA main board 7 and the keyboard lower cover 9. Anti-slip pads 10 are adhesively bonded to the four corners of the bottom of the keyboard lower cover 9. The reinforcing plate 8 can increase the overall weight of the keyboard (to improve the overall stability of the keyboard) and at the same time play a role in assisting in supporting the PCBA main board 7.

[0030] Among them, the reinforcing plate 8 is preferably made of fiberglass material, but no limitation is made here.

[0031] Further, it further includes a connecting line 2. One end of the connecting line 2 extends into the accommodation space and is electrically connected to the PCBA main board 7. The connecting line 2 is a USB connecting line. Through the connecting line 2, the keyboard can be communicatively connected to a computer.

[0032] In summary, a color recognition module 5 is added to the keyboard. When the user uses it, just place an item of the color he likes in front of the color recognition module 5 for a few seconds. The color recognition module 5 will recognize the color of the item, and after recognition, automatically set the keyboard backlight color to be the same as it, which can make the keyboard backlight more coordinated with the colors of surrounding items or devices, and greatly improve the visual and experience effects of players.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
