Further, the extended portion 211 extends out of the positioning plate 22 along the width direction of the inner container 2 and extends along the length direction of the inner container 2. The light source 6 is a single-color LED or an RGB LED. A plurality of light sources 6 are arranged at intervals along the length direction of the inner container 2 and are fixedly attached to the upper surface of the extended portion 211. The interface assembly 23 is used for charging. The interface assembly 23 is electrically connected with the circuit board 21 and is fixedly connected to the edge of the upper surface of the extended portion 211.

[0035] Referring to Figure 2 and Figure 4 , the housing 1 and the inner container 2 form a containing position 100. The containing position 100 has a light outlet 101 arranged on the outer surface of the keyboard. In the present embodiment, the face cover of the housing 1 is provided with a frame portion 11 in addition to the window for exposing the key shaft and the key cap. The containing position 100 and the light outlet 101 are formed on the inner periphery of the frame portion 11. That is, the frame portion 11 surrounds the containing position 100 from the outer periphery. The extended portion 211 is located at the bottom of the containing position 100. That is, the containing position 100 is formed between the frame portion 11 and the extended portion 211. The light source 6 faces upward and is opposite to the containing position 100 and the light outlet 101. In addition, part of the interface assembly 23 is located in the containing position 100.

[0036] Referring to Figure 3 and Figure 4 , the light-transmitting member 5 is a glass block. The light-transmitting member 5 has a three-dimensional pattern 59 formed by laser engraving. Laser engraving is a prior art technique. In the present embodiment, the light-transmitting member 5 extends in the length direction of the keyboard to form an elongated strip and extends between the two ends of the length of the keyboard.

The light-incident surface 508 is the bottom surface of the light-transmitting member 5, and the light-emitting surface 509 is the top surface of the light-transmitting member 5. The upper portion of the light-transmitting member 5 is a convex portion 51, and the light-emitting surface 509 is the top surface of the convex portion 51. In addition, as shown in Figure 4 , in the present embodiment, the two side surfaces of the light-transmitting member 5 in the width direction of the keyboard are provided as diffuse reflection surfaces 53. In addition, as shown in Figure 3 , a plurality of avoiding recesses 52 are arranged on the light-transmitting member 5. Some of the avoiding recesses 52 are arranged on the side surface where the diffuse reflection surface 53 is located. One of the avoiding recesses 52 is arranged between the side surface where the diffuse reflection surface 53 is located and the bottom surface of the light-transmitting member 5 as a recess for cooperating with the interface assembly 23.

Of course, the light-transmitting surface 509 is exposed outside the keyboard from the light outlet 101. When the light source 6 emits light, the laser engraving three-dimensional pattern 59 in the light-transmitting piece 5 is more eye-catching, and a more interesting light effect is obtained. Of course, the light source 6 can directly serve as an indicator lamp, and the dynamic change or color change of the light source 6 can prompt the user of the current state, so that the prompt light effect of the keyboard is presented in a different light effect from the past. In addition, the diffuse reflection surface 53 can shield the internal structure of the keyboard, so that the internal structure of the keyboard is not presented to the user through the transparent light-transmitting piece 5, and the visual beauty is ensured. In addition, the convex part 51 increases the height of the light-transmitting piece 5, enhances the settable height of the laser engraving three-dimensional pattern 59, and thus improves the degree of freedom and three-dimensionality of the engraving three-dimensional pattern 59. The three-dimensional pattern 59 can be a three-dimensional logo, a three-dimensional figure, a dynamic, plant image, or a cartoon animation figure. In addition, the light-transmitting piece 5 of the embodiment is in a strip shape, has sufficient space for engraving multiple three-dimensional patterns, and can cooperate with the different color light emission of the light source 6 for different three-dimensional images, so as to meet the engraving pattern and light effect requirements of various themes.
