Abstract
The utility model discloses a key core structure using a 360-degree flexible light-emitting light bar as backlight, which comprises a key core main body and a flexible light-emitting light bar, and the flexible light-emitting light bar is arranged on the back surface of the key core main body in a snakelike wire arrangement mode and passes through the lower part of each key in the key core main body. The flexible light-emitting lamp strip is used for achieving dead-corner-free and uniform backlight operation, a plurality of buckles which are connected with the flexible light-emitting lamp strip in a matched and clamped mode are arranged on the back face of a bottom plate of the key core body along a flexible light-emitting lamp strip winding displacement path, and the flexible light-emitting lamp strip is fixed to the back face of the key core body through the buckles. According to the utility model, the flexibility of the flexible light-emitting lamp strip is utilized, the lamp strip is arranged on the lower layer of the key core in a snakelike wiring manner, the lamp strip passes through the lower part of each key, and light emitted by the flexible light-emitting lamp strip can penetrate through the hole designed on the key core and then can penetrate out of the key cap, so that a backlight effect is achieved; the keyboard has the advantages of high luminance and uniformity, and can well overcome the defects of backlight of a traditional keyboard.
