The specific embodiments adopted by the present invention will be further described by the following embodiments and drawings.

As shown in the first to third figures, in the first embodiment of the present invention, the user device 100 is a notebook computer, which includes a cover 21 , a screen 22 , a casing 11 , a light-emitting keyboard 1 and a motherboard (in the figure omitted not shown). The cover body 21 is integrated with the screen 22 , the cover body 21 and the casing 11 are pivotably connected, and the screen 22 can be a general display or a touch screen. The light-emitting keyboard 1 and the main board are arranged on the casing 11 . The main board is hidden in the casing 11 , and the light-emitting keyboard 1 is partially exposed on the upper surface of the casing 11 . The casing 11 also has a palm rest area 113 juxtaposed with the light-emitting keyboard 1 . The lines connecting the geometric centers of the key assemblies 15 are coplanar or parallel. In the present invention, the key covering member 2 refers to an element used to cover the light-emitting keyboard 1 . For example, when the cover 21 is covered with the casing 11 and the upper surface of the casing 11, the screen 22 covers the light-emitting keyboard 1 and can be used as a key cover 2 to cover the light-emitting keyboard 1 alone; in other embodiments, the cover 21 and the The screen 22 may also cover a part of the light-emitting keyboard 1 respectively. In this case, the key cover 2 is realized by the cover 21 and the screen 22 together.

A single or a plurality of key holes 112 (only one is marked in the figure) is formed on the upper surface of the casing 11 to correspond to one or more or all of the key components 15 , and a gap frame 111 is formed between the adjacent key holes 112 . In some embodiments, the slot frame 111 is not provided, and at this time, only a single key hole 112 is opened in the casing 11 to surround the outer periphery of all the plurality of key assemblies 15 . When a plurality of key holes 112 are formed on the upper surface of the casing 11 , the gap frame 111 surrounds the key assembly 15 and the key cap 152 , so that the entire gap frame 111 forms a porous mesh structure.

The light-emitting keyboard 1 includes a plurality of key assemblies 15 , a thin film circuit 14 , a bottom plate 16 , a lighting module 12 , a disinfection module 13 and a reflective film layer 17 .

Each key assembly 15 includes a key cap 152 , a lifting mechanism 151 and a trigger structure 153 . In principle, the key caps 152 pass through the key hole 112 and the slot frame 111 and are located at a uniform height, and all the key caps 152 are disposed opposite to the bottom plate 16 . The lifting mechanism 151 is disposed between the key cap 152 and the bottom plate 16 , so that the key cap 152 can move up and down relative to the bottom plate 16 . In practice, the lifting mechanism 151 can be realized by a scissor foot, a butterfly or a bat mechanism, and the bottom plate 16 has a buckle structure (not shown) connected to the bottom end of the lifting mechanism 151 . The trigger structure 153 is disposed between the keycap 152 and the thin film circuit 14. The trigger structure 153 can be realized by, for example, an elastic element with bumps, and is driven by the keycap 152 to press and conduct a switch (not shown) disposed on the thin film circuit 14. .

A character area TA is defined on the upper surface of the keycap 152 . For example, the keycap 152 includes a transparent cap body 1521 and an opaque paint layer 1522; the cap body 1521 is fixed on the top of the lifting mechanism 151, the paint layer 1522 is coated on the surface of the cap body 1521, and the paint layer 1522 is provided with character perforations 1523 to Define the light-transmitting character area TA. In other embodiments, the cap body 1521 may be an opaque cap body, and the light-transmitting character area TA is defined by means of hollowing, micro-perforation, etc., so the paint layer 1522 is not absolutely necessary. In addition, there is a gap area GA between the key caps 152 of any two of the plurality of key assemblies 15 . In the orthographic projection direction, the gap area GA mostly coincides with the gap frame 111 . If the gap frame 111 can transmit light (whether visible light or invisible light), the gap area GA can completely transmit light. If the gap frame 111 can only partially transmit light, for example, it can block visible light but allow invisible light (such as ultraviolet light) to pass through, only the gap between the keycap 152 and the gap frame 111 in the gap area GA can pass visible light, but the entire gap area GA can pass visible light. Both GAs allow invisible light to pass through. Thereby, in the area shielded by the casing 11 and the plurality of key assemblies 15 (especially the key caps 152 ), a plurality of areas such as the character area TA and the gap area GA can transmit light.

The thin film circuit 14 is located under the keycap 152 , and the thin film circuit 14 is disposed opposite to the bottom plate 16 . In various embodiments, the thin film circuit 14 may be stacked above or below the base plate 16 . The thin-film circuit 14 has a key circuit (not shown) and a plurality of switches (not shown). The key circuit is connected to a plurality of switches (not shown) located under each key cap 152, and a key signal is generated when the switch is triggered. The thin-film circuit 14 can be realized by printing a key circuit on a single-layer or multi-layer thin film; in this embodiment, the thin-film circuit 14 can at least partially transmit light.

The lighting module 12 includes a plurality of lighting light sources 122 (only one is marked in the third figure), and the disinfection module 13 includes a disinfection light guide plate 131 and a plurality of disinfection light sources 132 (only one is marked in the figure); wherein, the disinfection light guide plate Both ends of the 131 are fixed to the two sides of the casing 11 , and the disinfection light source 132 and the illumination light source 122 are arranged on the side of the disinfection light guide plate 131 in a staggered arrangement. The illumination light source 122 can be arranged on the side of the light guide plate 131 and the disinfection light source 132 is staggered in the vertical direction as shown in the third figure. Thereby, the illuminating light emitted by the illuminating light source 122 is guided to be totally reflected in the sterilizing light guide plate 131 and transmitted laterally. In addition, a light-shielding layer can be arranged above the disinfection light guide plate 131 to define the light-exiting position, and a light-reflecting layer can be selectively arranged above and below the disinfection light-guiding plate 131 to reduce light loss. At the corresponding light-exiting position, a microstructure or Diffuse paint spots, so that lighting and disinfection light can be turned and emitted.

In this embodiment, the bottom plate through holes 161 formed in each bottom plate 16 correspond to the key caps 152 of each key assembly 15 respectively. The illumination light source 122 in this embodiment can be a light-emitting diode, and the illuminating light emitted is visible light; in addition, the illumination light source 122 can be a single or multiple light-emitting diodes, such as red, green and blue light-emitting diodes integrated into one body .

In principle, the components above the sterilization module 13 must be transparent to invisible light, whether they are made of light-transmitting materials (such as the thin film circuit 14 ), or holes that define penetration (such as openings in the lighting module 12 , the bottom plate, etc.). 16) to serve as a light path for the sterilizing light. In different embodiments, the sterilizing light guide plate 131 can be disposed above or below the bottom plate 16, and can also be disposed above or below the thin-film circuit 14; similarly, the disinfecting light guide plate 131 can be disposed above or below the bottom plate 16, or can be disposed above or below the bottom plate 16. Above or below the thin film circuit 14 .

As shown in the first, fourth and fifth figures, the user device 100 of this embodiment has an operation mode and a sterilization mode, and the light-emitting keyboard 1 is used in conjunction with the key cover 2 . When the key cover 2 does not cover the light-emitting keyboard 1, the user device 100 and the light-emitting keyboard 1 are in the operation mode, as shown in the first and fourth figures; when the key cover 2 covers the light-emitting keyboard 1, the user device 100 The light-emitting keyboard 1 is in the disinfection mode, as shown in the second and fifth figures.

Light path), the illuminating light will be projected to the character area TA (ie the character perforation 1523) that penetrates the keycap 152 through the sterilizing light guide plate 131, and the illuminating light can also be projected from the gap between the keycap 152 and the slot frame 111. In the operating mode, the disinfection light source 132 is not functional. In addition, since there is a reflective film layer 17 under the disinfection light guide plate 131 , the illuminating light or the disinfection light projected into the disinfection light guide plate 131 can be reflected by the light reflection film layer 17 to concentrate upwards.

However, when the user device 100 and the light-emitting keyboard 1 are in the disinfection mode as shown in the second figure, the disinfection light source 132 will emit disinfection light (not shown) as shown by the light path arrow in the fifth figure, and the disinfection light is also passed through the disinfection guide. The light plate 131 projects and penetrates the cap body 1521 and projects from the character through holes 1523 (character area TA), and the disinfection light also passes through the gap between the key cap 152 and the slot frame 111 . If the gap frame 111 is permeable to invisible light (such as ultraviolet light), the disinfection light may also be directly or indirectly reflected through the key assembly 15 and then exit through the gap frame 111, that is, the entire gap area GA allows the disinfection light pass through. At this time, since the key cover 2 is covered on the luminous keyboard 1 and the upper surface of the casing 11 , the disinfection light can sterilize the surface of the key cover 2 (the screen 22 and/or the cover 21 ). In addition, the disinfection light projected from the key gap between the character perforation 1523 and the keycap 152 is projected to the main disinfection area 23 of the key cover 2 in the first figure (which may cover the screen 22 and/or the cover 21), and then It is further reflected to the surface of all keycaps 152, thereby achieving the effect of sterilization. In the disinfection mode, the lighting module 12 may not function. In addition, as long as the disinfection light source 132 has sufficient luminous power, the disinfection light can be repeatedly reflected between the key cover 2 and the key cap 152, the key cover 2 and the upper surface of the casing 11, and the disinfection light does not need to be affected by the light emitting area, The limitation of the light output position can reach every part of the key cover 2 through multiple reflections, and even reach areas other than the orthographic projection of the illuminated keyboard 1, such as the palm rest area 113 and the key cover 2 on the casing 11 in the first figure. The auxiliary disinfection area 24, the palm rest area 113 faces the key cover 2 in the disinfection mode. The main disinfection area 23 of the key cover 2 can be defined as, when the key cover 2 covers the light-emitting keyboard 1, the light-emitting keyboard 1 is in the orthographic projection area of the key cover 2; on the contrary, the auxiliary disinfection area 24 of the key cover 2 is: The area of the illuminated keyboard 1 other than the orthographic projection of the key cover 2 can also be regarded as an area other than the main disinfection area 23 .

In this embodiment, the illuminating light source 122 is a light-emitting diode, and the illuminating light it projects is visible light such as white light or yellow light, and the disinfection light source 132 is also a light-emitting diode, and the sterilizing light it projects is ultraviolet light Light; however, in other embodiments, it is not limited to ultraviolet light, but can also be visible light, infrared light, or other light that can achieve disinfection, sterilization, or deactivation and inactivation effects. For example, blue light (visible light) with a wavelength of 405 nanometers shows a broad-spectrum antibacterial effect on Gram-negative bacteria and Gram-positive bacteria, while visible light femtosecond lasers (Femtosecond Lasers) or near-infrared sub-picosecond fiber lasers Radiation inactivates a variety of viruses, including M13 bacteriophage, murine cytomegalovirus, tobacco mosaic virus, human papilloma virus, and human immunodeficiency virus. In addition, the principle of photodynamic therapy (PDT) can also be applied to the disinfection light source 132. Since its biological targets (proteins, lipids, nucleic acids) are the main components of all kinds of microorganisms and their derivatives, non-toxic photosensitizers (such as Coated on the surface to be sterilized in various places of the present invention) to match with visible light or near-infrared light, it can produce a sterilizing effect on microorganisms and their derivatives.

The illumination light guide plate 121 is disposed between the bottom plate 16 and the disinfection light guide plate 131 , and the illumination light source 122 is disposed on the side of the illumination light guide plate 121 for projecting illumination light from the side of the illumination light guide plate 121 to the illumination light guide plate 121 middle.

Continuing from the above, the disinfection module 13 is also used to project the disinfection light when the user device 100 is in the disinfection mode in which the key cover 2 is covered with the light-emitting keyboard 1, so that the disinfection light is also projected through the disinfection light guide plate 131 and passed through. Through the cap body 1521, it is projected from the character perforation 1523 (character area TA), and the sterilizing light will also pass through the gap between the key cap 152 and the slot frame 111, and then the key cover 2 (the screen 22 and/or the cover body 22 and/or the cover body. 21) surface disinfection.

On the other hand, when the user device 100 and the light-emitting keyboard 1 are in the operation mode, the lighting module 12 projects the lighting light to the lighting light guide plate 121 through the lighting light source 122 , so that the lighting light penetrates the cap body 1521 and passes through the character perforations 1523 ( The character area TA) is projected and protrudes from the gap between the keycap 152 and the slot frame 111 .

Furthermore, as shown in FIG. 7 and FIG. 8, the third embodiment of the present invention is similar in design to the first embodiment, and the main difference lies in that the lighting module 12 is stacked on the light-emitting keyboard 1 of the third embodiment. Above the disinfection module 13, the disinfection light will pass through the lighting circuit board 123 of the lighting module 12 and pass through the character area TA and/or the gap area GA. The lighting circuit board 123 of the lighting module 12 is disposed between the disinfection light guide plate 131 and the bottom plate 16 , and the lighting light source 122 is disposed on the lighting circuit board 123 and passes through the bottom plate 16 . In other embodiments, the disinfection module 13 can also be stacked above the lighting module 12 and the lighting circuit board 123, and the lighting light will pass through the disinfection module 13 and out of the character area TA. In addition, in the present embodiment, the position of the illumination light source 122 is disposed under the spacer frame 111 or the gap area GA, so the spacer frame 111 may not be disposed in the gap area GA.

Furthermore, as shown in FIG. 9 , the position of the illumination light source 122 can also be moved below the key assembly 15 , so that the illumination light can pass through the character area TA or the gap area GA of the keycap 152 . It should be added that since the lighting module 12 is disposed above the disinfection light guide plate 131, the lighting module 12 is further provided with a plurality of circuit board through holes 1211 (only one is marked in the figure), so that the disinfection light guide plate 131 located below The projected disinfection light can be projected to the key assembly 15 through the through hole 1211 of the circuit board, and even projected from the character area TA and the gap area GA.

In addition, the specific material can improve the transmittance of the short-wavelength sterilizing light, and increase the light intensity of the sterilizing light passing through the key assembly 15 . The dashed and solid lines in Figure 10 show the intensity of disinfection light (ultraviolet light) measured on several different key positions (key positions) of the key assembly 15 with two different lifting mechanisms (such as the lifting mechanism 151 in Figure 5). . The dotted line of data 1 is the test group adding glass fiber to the lifting mechanism, and the solid line of data 2 is the lifting mechanism of the opposite group and using general materials. The results show that the UV light intensity of the dotted line-test group at each bond position is much higher than the solid line-measured value of the pair at the corresponding bond position. In terms of the average value, the average measurement value of the solid line-paired group at all key positions is 4.8 nits, but the dotted line-test group has an average UV light intensity of 17.5 nits at all key positions, highlighting the high transmittance of invisible light. The buff effect of the material on the intensity of the disinfection light. The main function of this type of invisible light gain material is to have a higher refractive index when the sterilizing light passes through, and to reduce the absorption rate or loss rate that is absorbed and broken by the key assembly 15 . In addition to glass fiber, the invisible light gain material can also be made of glass particles; as for the target element to which the gain material is added, in addition to the lifting mechanism 151, it can also be added to the keycap 152, the trigger structure 153, and even the thin-film circuit 14 or the bottom plate 16.
