[0031] The utility model provides a key structure 1000 .

[0032] See also Figures 1 to 4 In one embodiment of the utility model, the key structure 1000 includes a key cover 1 and a pressing member 2, the key cover 1 is provided with a accommodating cavity 11 and a limiting groove 12, a light-transmitting area 111 is formed between the accommodating cavity 11 and the limiting groove 12; the pressing member 2 is accommodated in the limiting groove 12 and cooperates with the side wall gap of the limiting groove 12, the pressing member 2 covers and connects the light-transmitting area 111, the pressing member 2 includes a light-transmitting portion 24 and a light-shielding portion 23, the light-transmitting portion 24 is arranged corresponding to the light-transmitting area 111; the light-shielding portion 23 includes a first light-shielding layer 231 and a second light-shielding layer 232, the first light-shielding layer 231 is arranged around the light-transmitting portion 24, and the second light-shielding layer 232 is connected to the first light-shielding layer 231 and is arranged on the outer peripheral wall of the pressing member 2.

[0033] In the technical solution of the present utility model, diffuse reflection will occur in the process of light emitted by the light-emitting body 2002 being transmitted to the light-transmitting part 24 through the light-transmitting area 111. The diffusely reflected part of the light will be blocked by the first light-shielding layer 231 and the second light-shielding layer 232, and cannot be emitted through the gap between the pressing member 2 and the side wall of the limiting groove 12, so that the light emitted by the light-emitting body 2002 can only be transmitted to the outside of the key structure 1000 through the light-transmitting area 111 and the light-transmitting part 24, thereby ensuring that the key structure 1000 will not leak light when in use, thereby improving the quality of the key structure 1000 and the user experience.

[0034] For further information, see Figure 3 , Figure 4 as well as Figure 5 In one embodiment of the utility model, the pressing member 2 includes a pressing cover body 21 and a light-transmitting pressing bracket 22, the light-transmitting pressing bracket 22 is connected to the button pressing cover 1, and is arranged corresponding to the light-transmitting area 111; the pressing cover body 21 is provided with a receiving groove 211, and the light-transmitting pressing bracket 22 is accommodated in the receiving groove 211, the pressing cover body 21 includes a light-transmitting portion 24 and a light-shielding portion 23, the light-transmitting portion 24 is arranged on the bottom wall of the receiving groove 211, the first light-shielding layer 231 is arranged around the light-transmitting portion 24, and the second light-shielding layer 232 is arranged on the outer peripheral wall of the pressing cover body 21. The light-transmitting pressing bracket 22 is provided to provide a stable support, so that the key structure 1000 will not shake or sway during use. This stability can ensure that the key can be accurately triggered when pressed, and can maintain consistent performance during long-term use; the light-transmitting pressing bracket 22 is arranged in the receiving groove 211, and can be more firmly fixed on the pressing cover 21 to avoid movement or loosening, and the first light-shielding layer 231 surrounds the light-transmitting portion 24, and the second light-shielding layer 232 is arranged on the outer peripheral wall of the pressing cover 21, so that the light emitted by the light-emitting body 2002 can only pass through the light-transmitting area 111, The light transmitted by the light-transmitting pressing bracket 22 and the light-transmitting portion 24 and diffusely reflected light are blocked by the first light-shielding layer 231 and the second light-shielding layer 232; the light-transmitting pressing bracket 22 is made of transparent plastic material, and about 1% of light diffuser is added to the transparent plastic, and the color is semi-transparent white. Adding the light diffuser can change the optical properties of the plastic material, so that the light is scattered multiple times inside the material instead of directly penetrating or reflecting. This scattering can make the light more evenly distributed on the surface of the material, thereby reducing the appearance of the yin and yang sides, and making the entire surface look more uniform in brightness, thereby making the light irradiation of part of the light-transmitting portion 24 more uniform.

[0035] To further prevent light leakage from the keys, refer to Figures 1 to 4In one embodiment of the utility model, the key structure 1000 includes a shading member 3, the two sides of which are connected to the key cover 1 and the pressing member 2, respectively. The shading member 3 is provided with a light-transmitting hole 31, and the light-transmitting hole 31 is arranged corresponding to the light-transmitting portion 24. The light emitted by the luminous body 2002 is transmitted through the light-transmitting area 111, the light-transmitting hole 31 and the light-transmitting portion 24 in sequence, so that the pressing member 2 is transparent. The shading member 3 extends and covers the light-transmitting area 111 to better achieve light shielding; the shading member 3 is a light-shielding double-sided adhesive. The shading member 3 can not only prevent the light from penetrating through the gap, but also realize the connection and fixation of the pressing member 2. The shading member 3, the first light-shielding layer 231 and the second light-shielding layer 232 jointly block the diffusely reflected light from propagating through the gap to the outside of the key structure 1000, further improving the key quality and user experience.

[0036] To improve the visibility of the key structure 1000, refer to Figure 2 and Figure 4 In one embodiment of the utility model, the key structure 1000 includes a light shielding sleeve 4, which is arranged in close contact with the inner wall of the accommodating cavity 11. The light shielding sleeve 4 can effectively reduce light leakage, so that the light is only focused on the light-transmitting area 111, thereby improving visibility and user experience; by limiting the propagation direction of light, the light shielding sleeve 4 can increase the light contrast in the key structure 1000, making the text or icon of the light-transmitting portion 24 more clearly visible, especially in a dark environment; the light shielding sleeve 4 can not only limit the propagation of light, but also protect the internal structure, prevent the intrusion of external factors such as dust and water vapor, and extend the service life of the key structure 1000.

[0037] To improve light transmission, see Figure 2 and Figure 4 In one embodiment of the utility model, the key structure 1000 includes a colorful film 5, which is disposed between the pressing cover 21 and the light-transmitting pressing bracket 22 and is disposed corresponding to the light-transmitting area 111. When the light-emitting body 2002 is not lit, the colorful film 5 can also make the light-transmitting part 24 present a colorful effect, and the setting of the colorful film 5 can enhance the light transmission effect, making the light emission of the key more uniform and bright. At the same time, the colorful film 5 can be used as a protective layer to protect the light-emitting body 2002 and other components under the key from being affected by the external environment, thereby extending their service life.

[0038] To improve the pressing feel of the key structure 1000, refer to Figure 4In one embodiment of the utility model, the bottom wall of the limiting groove 12 is formed with an arc-shaped deformation part 121. The arc-shaped deformation part 121 can provide more uniform force transmission, thereby reducing the uneven feeling of the pressing member 2 when it is pressed down. Compared with the flat design, the arc-shaped surface can better adapt to the pressure distribution of the finger, making the hand feel more natural and comfortable; and the thickness of the arc-shaped deformation part 121 is thinned, which can increase the sensitivity of the pressing member 2, so that the force required to press the pressing member 2 is smaller, and the pressing member 2 feels softer. The arc-shaped deformation part 121 can be deformed to a certain extent when subjected to force, and then return to its original state. This design can enable the pressing member 2 to better adapt to the shape and pressure of the finger when it is under pressure, thereby reducing the discomfort in the hand feel.

[0039] Furthermore, in an embodiment of the present invention, please refer to Figure 1 , Figure 2 as well as Figure 4 The key structure 1000 includes a mounting body 6, a PCB board 2001, and a light emitting body 2002 electrically connected to the PCB board 2001.
