Please refer to Fig. 1 to Fig. 4, this invention is a kind of multi-point backlit keyboard, which is composed of a plurality of light-transmitting keycaps 10, a plurality of bridging structures 20, a light-transmitting keyboard frame plate 30, a transparent circuit layer 40, a The LED backlight layer 50 and the bottom plate 60 are composed.

The light-transmitting keycap 10 is made of light-transmitting material (or transparent material), and it is a light-transmitting pressing element generally in a square shape.

The bridging structure 20 is an integral rotating structure formed by a first frame 21 and a second frame 22 pivoted by cross shafts, and two corresponding sliding shafts 211 extending inward from both sides of the top edge of the first frame 21 are The two corresponding pivots 221 on the top edge of the second frame 22 are pivotally connected to the bottom surface of the light-transmitting keycap 10 in a rotatable manner. The two correspond to the pivot joint slots 14, and then, the two corresponding sliding shafts 222 extending outward on both sides of the bottom edge of the second frame 22 are slidably accommodated in two upwardly bent light-transmitting keyboard frame plates 30. Corresponding to the slide guide groove 32, and the corresponding pivot shaft 212 of the bottom edge of the first frame 21 is pivotally connected to the upwardly bent corresponding receiving groove 31 of a light-transmitting keyboard frame plate 30. Therefore, the bridging structure 20 The top edge and the bottom edge can be pivotally connected between the light-transmitting keycap 10 and the light-transmitting keyboard frame 30 respectively, so as to form a bridge-type key structure.

The light-transmitting keyboard frame 30 is made of light-transmitting material (or transparent material). The light-transmitting keycap 10 is pierced with a plurality of light-transmitting elastic elements 38 on the frame plate, and the tops of the several elastic elements 38 are respectively corresponding to the pressing parts 18 on the bottom surface of the several light-transmitting keycaps 10 As for, the pressing column (not shown in the figure) in the plurality of elastic elements 38 can be pressed down to touch and conduct the transparent circuit layer 40 .

The transparent circuit layer 40 is a long thin film circuit board structure for conducting key signals, and it is located between the light-transmitting keyboard frame plate 30 and an LED backlight layer 50 .

The LED backlight layer 50 is an LED backlight board, the top surface is provided with a plurality of LED elements 51 arranged in a matrix, and the distribution range of each of the LED elements 51 corresponds to the distribution range of each of the light-transmitting keycaps 10, so that each A light-transmitting keycap 10 corresponds to a plurality of LED elements 51 respectively. Certainly, according to the difference in size of each of the light-transmitting keycaps 10, the corresponding number of the LED elements 51 is also different, for example: under the A key with a smaller size The square corresponds to twenty LED elements 51 , and the bottom of the larger enter key corresponds to forty LED elements 51 . In terms of structural design, the LED element 51 is a multi-color light-emitting diode (RGB LED), which can be driven to generate light sources of various colors, and the light source passes through the transparent circuit layer 40, the light-transmitting keyboard frame plate 30, the The bridging structure 20 penetrates the light-transmitting keycap 10 to form a light effect. In terms of driving, each LED element 51 can be independently controlled to switch to emit light or not emit light, and adjust the color of the light source when the LED element 51 emits light, so that the LED elements 51 that emit light are arranged to form a single color or a mixture of multiple colors. The resulting images (for example: characters, graphics, symbols) are transmitted through each of the light-transmitting keycaps 10 to generate corresponding image light effects.

And the base plate 60 is a plate body supporting the light-transmitting keyboard frame plate 30, the transparent circuit layer 40 and the LED backlight layer 50, so that it can be assembled into a complete keyboard key structure.

The image application of the creative multi-point backlit keyboard is further described below.

As shown in Figure 3, assume that some of the LED elements 51 are set to emit light, and are arranged and combined into characters such as MATRIX, wherein the light source color of each LED element 51 corresponding to MTI is blue, and each LED element 51 corresponding to AR is blue. The color of the light source is yellow, the color of the light source of each of the LED elements 51 corresponding to X is red, and the LED elements 51 in other parts are set to not emit light. A dotted LED element 51 indicates no light emission). As shown in Fig. 4, at this moment, the light source of each luminous LED element 51 will pass through the light-transmitting keycap 10, and form a colored MATRIX light effect on each of the light-transmitting keycaps 10, so that the keyboard has a technological Sensitive text lighting effects. Certainly, besides being presented in a single color, English letters can also be changed through the color change of the light source of each LED element 51, so that the same English letter can have multiple light colors; When two different color light sources are generated (for example: each LED element 51 on the left half of the letter M is a blue light source, and each LED element 51 on the right half of the letter M is a yellow light source), the letter M can be formed to form a two-color light effect, Furthermore, the light-transmitting keycap 10 presents a dazzling text lighting visual effect. Also, in addition to text In addition to the display, each luminescent LED element 51 can also be set as an arrangement of graphics or symbols (for example: Olympic graphics, exclamation marks or question marks), or a combination of words, graphics, and symbols, depending on user needs.

From the above description, it can be known that the invention forms a multi-point light source array through the LEDs arranged in a matrix, and achieves the control of the color of the light source by using the LED elements 51 to emit or not emit light, and at the same time cooperate with the full-color effect of RGB LEDs. Furthermore, various single-color or multi-color characters, graphics, and symbols can be formed on each of the light-transmitting keycaps 10, so that the lighting of the keyboard has dazzling and rich color effects, and at the same time has unique recognition.

In addition, regarding the control of each of the LED elements 51 , it includes at least two ways of setting in advance or setting by the user. The preset method is that the keyboard itself has built-in various images, for example: the firmware (Firmware, referred to as FW) is written in the keyboard’s microcontroller (Micro Control Unit, referred to as MCU). The provided switch or specific key can control each of the LED elements 51 to switch various preset images, and then form graphics, characters or symbols with monochromatic or colored lighting effects on each of the light-transmitting keycaps 10 . The way to set it yourself is to connect the multi-point backlit keyboard of this creation to electronic devices such as computers, smart phones, tablet computers or notebook computers in a wired or wireless manner, and set, control and set various settings through the above electronic devices. Whether or not the LED element 51 emits light and the color of the light is used to form light effects such as characters, symbols or graphics. For example, when the electronic device is a smart phone, the multi-point backlit keyboard of this invention can be connected to the smart phone through built-in bluetooth or wifi, and the image setting can be performed through the smart phone APP to control various functions. The light emission and color of the LED element 51 form a light effect on the light-transmitting keycap 10 .

To sum up, this creation is a multi-point backlit keyboard, which is assembled with an LED backlight layer in a thin bridge-type keyboard, and it mainly uses a plurality of RGB LEDs arranged in a matrix to illuminate the colored lights. The source is projected onto the light-transmitting keycap to achieve the effect of displaying multi-color light-transmitting images on the light-transmitting keycap. Therefore, the multi-point backlit keyboard created by this invention is indeed innovative and progressive, and it is in line with the requirements of our country.
