Referring to Figures 1 to 3 As shown in the figure, the light guide key mentioned above includes a switch module 1000, a light guide element 2000, and a touch element 3000. The switch module 1000 includes a module base 1100, a switch assembly 1200, and a light-emitting assembly 1300, as Figure 4 As shown in the figure, the switch assembly 1200 and the light-emitting assembly 1300 are assembled in the module base 1100, wherein the switch assembly 1200 realizes the switching function of the switch module 1000, that is, pressing the switch assembly 1200 can realize the opening or closing of the path, and the light-emitting assembly 1300 is configured to emit a light source, for example, the light-emitting assembly 1300 uses an Led light source.

[0054] Regarding the design of the switching function and the light-emitting function in the light guide key mentioned above, referring to Figures 5 to 8 As shown in the figure, the light guide element 2000 includes an element base 2100 and a trigger arm 2200, and the trigger arm 2200 is assembled in the element base 2100. The light guide element 2000 is made of a material with light guide function, and is mainly used to form a trigger cooperation with the switch module 1000, that is, the trigger arm 2200 is configured to trigger the switch assembly 1200 to realize the pressing of the switch assembly 1200, thereby controlling the opening or closing of the switch assembly 1200. Continue to refer to Figure 8 As shown in the figure, the element base 2100 is provided with a light transmission area 2110, which is configured to transmit the light source emitted by the light-emitting assembly 1300. The size and shape of the light transmission area 2110 can be designed according to actual conditions, such as square, circular, etc., without limitation.

[0055] The pressing element 3000 is connected with the light guide element 2000, for example, the pressing element 3000 is inserted and assembled with the light guide element 2000, and meanwhile, the pressing element 3000 can be fixed by means of hot melting or the like. Wherein, the fool-proof structure can be arranged between the pressing element 3000 and the light guide element 2000, so as to ensure that the assembly between the pressing element 3000 and the light guide element 2000 is more convenient. The user mainly realizes the touch control of the light guide element 2000 by touching the pressing element 3000, so as to trigger the switch assembly 1200 of the switch module 1000 by means of the light guide element 2000. Therefore, when the user touches the pressing element 3000, the switch assembly 1200 of the switch module 1000 can be triggered by means of the light guide element 2000. At this time, the light emitting assembly 1300 of the switch module 1000 is also triggered, so that the light emitting assembly 1300 emits light source. For example, in one embodiment, the switch assembly 1200 and the light emitting assembly 1300 are electrically connected. Wherein, the light guide element 2000 is provided with a light transmission area 2110, and the position of the light transmission area 2110 is just corresponding to the light emitting assembly 1300, so that the light transmission area 2110 can transmit the light source emitted by the light emitting assembly 1300, so as to realize the light guide function of the light guide key.

[0056] Referring to Figures 1 to 8 In the structure design of the light guide key, the switch function and the light guide function of the light guide key are mainly realized by the mutual assembly relationship among the switch module 1000, the light guide element 2000 and the pressing element 3000, which includes the characteristics of the structure design of the switch module 1000, the light guide element 2000 and the pressing element 3000 and the design of the relative position relationship among them.

[0057] Therefore, the light guide key does not need the complex process such as expensive paint spraying and laser engraving, and does not need the material such as expensive polycarbonate (PC) or polymethyl methacrylate (PMMA), and the switch function and the light guide function of the light guide key can be realized by the assembly of the switch module 1000, the light guide element 2000 and the pressing element 3000, the assembly process is relatively simple, and the assembly difficulty problem is not easy to occur, so that the production cost of the light guide key can be effectively reduced, the uniform light transmission effect can be ensured, and the switch function and the light guide function of the light guide key can be realized.

[0058] Continuing to refer to Figure 5 and Figure 6As shown, the switch assembly 1200 can include at least two switch trigger portions 1210, and a plurality of the switch trigger portions 1210 are arranged around the light emitting assembly 1300. The light guide element 2000 includes at least two trigger arms 2200, and a plurality of the trigger arms 2200 are arranged around the light transmission region 2110.

[0059] Referring back to Figure 7 and Figure 8 As shown, the touch element 3000 is provided with a light guide hollow 3001, and the light transmission region 2110 is arranged opposite to the light guide hollow 3001 and is configured to transmit the light source emitted by the light emitting assembly 1300. The element base 2100 is provided with a light guide protrusion 2120, and the light guide protrusion 2120 penetrates the light guide hollow 3001 of the touch element 3000. In one embodiment, the cross-sectional area of the light guide protrusion 2120 gradually decreases in the direction away from the element base 2100. Moreover, the light guide protrusion 2120 is arranged in the light transmission region 2110, and the maximum cross-sectional area of the light guide protrusion 2120 is smaller than the area of the light transmission region 2110.

[0060] Referring back to Figures 1 to 3 As shown, in one embodiment, the light guide key includes a fixed support 4000 and a key shell 5000, the switch module 1000 is assembled in the fixed support 4000, and the touch element 3000 is assembled in the key shell 5000, for example, by means of hot melting or the like. Thus, the positioning and assembly of the above-mentioned switch module 1000, light guide element 2000 and touch element 3000 are achieved. In one embodiment, the touch element 3000 includes a touch base 3100 and a deformation arm 3200 connected to each other, and the touch base 3100 is movably assembled in the key shell 5000 through the deformation arm 3200. The deformation arm 3200 can be configured to have elastic deformation capability. Moreover, the deformation arm 3200 can be made of plastic or the like. When the user presses the touch base 3100, the deformation arm 3200 can be deformed under force, and then relatively moves relative to the key shell 5000, but based on the connection of the deformation arm 3200, the touch base 3100 does not separate from the key shell 5000.

[0061] In one of the embodiments, the number of the deformation arms 3200 is configured to be at least two, one end of the deformation arms 3200 is connected to the pressing seat 3100, and the other end of the deformation arms 3200 is connected to the key shell 5000.

The key shell 5000 is provided with a limiting structure 5100, and the limiting structure 5100 is configured to limit contact with at least one of the light guide element 2000 and the pressing element 3000. Therefore, based on at least one of the limiting element 6000 and the limiting structure 5100, the movement stroke of the light guide element 2000 and the pressing element 3000 can also be limited, so that when the light guide element 2000 and the pressing element 3000 reach a certain stroke, they cannot continue to be pressed, preventing the deformation arms 3200 from being deformed due to excessive stress. In one of the embodiments, the limiting element 6000 and the limiting structure 5100 are respectively arranged on both sides of the pressing element 3000, one side of the pressing element 3000 is configured to limit contact with the limiting element 6000, and the other side of the pressing element 3000 is configured to limit contact with the limiting structure 5100.
