Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic device input component technology, and in particular to a key that can emit light in low-light environments, and a luminous component for making the key emit light. Background Technology
[0002] Enabling electronic device buttons to emit light helps users accurately identify button locations and functions in dark or poorly lit environments, improving ease of operation. One way to achieve this is to make the buttons glow in the dark.
[0003] The existing technologies for making buttons glow in the dark mainly include the following: The first method involves printing luminescent material directly onto the button surface as the key display characters. Printing luminescent material onto the button surface has several drawbacks: First, with prolonged contact with fingers, the luminescent material risks detaching from the button surface; second, luminescent materials are mostly mineral-based, and printing too thickly results in a rough surface and poor tactile feedback, while printing too thinly results in insufficient brightness and poor wear resistance, causing the characters to wear and become blurred over time.
[0004] The second method involves printing luminescent material first, and then transferring it to the button surface. This method also suffers from the problem of the luminescent material easily peeling off, and it is also limited by thickness, making it impossible to balance tactile feel and luminous effect.
[0005] The third method involves creating a silicone keyboard cover with added luminescent material, which is then applied to the surface of the computer keyboard. This approach increases the resistance to key presses, affecting the typing feel. Furthermore, the amount of luminescent material in the keyboard cover is limited, resulting in poor luminescence. Since it does not optimize the structure of the keys themselves, the user experience is subpar.
[0006] Therefore, there is an urgent need for a luminous button structure that can ensure good luminous effect, solve problems such as luminous material peeling, poor tactile feel, and insufficient wear resistance, without affecting the mechanical strength and service life of the button itself. Summary of the Invention
[0007] The present invention aims to at least partially solve one of the technical problems in the aforementioned technologies. Therefore, the purpose of the present invention is to propose a luminous button and a luminous component that can solve the problems of easy luminous material detachment, poor tactile feel, and insufficient wear resistance in existing luminous buttons.

[0019] The luminescent key of the present invention fundamentally avoids the problems of luminescent material falling off and wearing out due to contact with the outside world by independently setting luminescent components between the keycap and the key membrane, while ensuring a smooth and comfortable pressing feel.

Detailed Implementation
[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0038] This application is based on the inventor's considerations regarding the following: Existing luminescent key manufacturing processes all place the luminescent material on the key surface, external accessories, or directly mix it into the keycap substrate, failing to balance luminescence effect, lifespan, tactile feel, and key mechanical strength. Among these, directly adding the luminescent material to the key's plastic raw material aims to make the entire key glow. However, luminescent materials are mostly organic, and when the luminescent material accounts for 10% of the key's mass, the key's impact resistance significantly decreases, making it prone to breakage; if the amount of luminescent material added is too small, the luminescence effect is poor. The solution using an independent luminescent component placed between the keycap and the key membrane avoids the luminescent material from contact with the outside environment, ensures a smooth pressing feel, maintains the original mechanical properties of the keycap without changing its material formula, and achieves clear character display through the perforated design of the key membrane, fundamentally solving the shortcomings of existing technologies.
[0039] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.
[0040] This invention provides a luminous button and a luminous component that enables the button to emit light. Preferred embodiments of the invention include embodiments of a single luminous button, embodiments of a luminous button combination of multiple buttons, and embodiments of an independent luminous component. This invention makes the button a luminous button, eliminating the need for an additional backlight, allowing users to clearly identify the button's function. The luminous button of this invention can be manufactured using different techniques, such as in-mold injection molding, in-mold vacuum forming, and other processes not described above.
[0041] Example 1 Please see Figure 1 and Figure 2 The luminous button 10 provided in this embodiment is a single-key luminous button. The button 10 has a keycap 12 and a key foot 15, through which the keycap 12 can move vertically. The outer surface of the keycap 12 has a top surface 13 and a peripheral surface 14 connected to the top surface. The button 10 includes a luminous component 20 and a key membrane 40. The key foot 15 shown in the figure is only an example; different types of buttons may have key feet with different structures.
[0042] The luminescent component 20 includes at least a luminescent film 21, such as Figure 3 As shown, the substrate of the luminescent film 21 is a transparent resin 23, and the substrate contains luminescent particles 22. Other embodiments of the luminescent film include... Figures 3 to 8 As shown.
[0043] Please see Figure 3 The luminescent component 20A of the first preferred embodiment of the present invention is a film material composed of a luminescent film 21 and a first adhesive layer 30.
[0044] The substrate of the luminescent film 21 contains luminescent material, namely luminescent particles (luminescent powder). In this preferred embodiment, the luminescent film 21 is made of a mixture of luminescent particles and resin. The resin used to mix with the luminescent particles can be various transparent polymer resins. The luminescent particles 22 are irregularly shaped tiny mineral particles, made of rare earth elements combined with alkaline earth aluminate or silicate, with a size of 5μm to 200μm. These particles emit light after absorbing energy. In this invention, the surface of the luminescent particles 22 is coated with a transparent, colorless resin. The transparent resin forms a coating layer 24 that completely isolates the luminescent particles 22 from the outside world, preventing them from contacting the environment, avoiding chemical reactions between the luminescent particles 22 and water or other substances, and preventing the luminescent particles from losing their luminescent function due to prolonged contact with water. The luminescent particles 22 coated by the coating layer 24 form microcapsule luminescent particles 25. It should be noted that each microcapsule luminescent particle 25 may contain one or more luminescent particles 22.
[0045] A suitable amount of microcapsule luminescent particles 25 are mixed with a transparent resin 23 to form a mixture, which is then used to make the luminescent film 21. The microcapsule luminescent particles are uniformly distributed within the luminescent film. The resin 23 of the luminescent film 21 can be, but is not limited to, polyurethane (PU) resin or thermoplastic polyurethane resin (TPU), which is transparent and colorless and does not obstruct light from entering or exiting the luminescent film. The transparent coating layer 24 has high light transmittance, allowing the luminescent particles 22 to effectively absorb light and store light energy. The light emitted by the luminescent particles 22 has increased transmittance through the coating layer 24, effectively emitting luminescence. Because the luminescent particles 22 are encapsulated by the coating layer 24 and do not react with the external environment, the service life of the luminescent film 21 is significantly extended.
[0046] In the luminescent film 21, the ratio of luminescent particles 22 to resin 23 is between 1:0.8 and 1:2, preferably between 1:0.9 and 1:1.3, so that the luminescent film 21 has a high luminous brightness.
[0047] The first adhesive layer 30 can be various adhesives or substances that can produce stickiness, such as, but not limited to, general adhesives, hot melt adhesives, and thermosetting resin adhesives, the latter two of which can produce stickiness when heated. Preferably, the thickness of the adhesive layer 30 is not greater than 0.035 mm, and more preferably not greater than 0.03 mm.
[0048] Please see Figure 4 The luminescent component 20B, as another preferred embodiment of the present invention, has a luminescent film 21, a first adhesive layer 30, and a second adhesive layer 32. The luminescent film 21 has a first surface (i.e., the bottom surface) and a second surface (i.e., the top surface) located on opposite sides. The first adhesive layer 30 is disposed on the first surface of the luminescent film 21, so that the luminescent component 20B is bonded to the keycap 12, and the second adhesive layer 32 bonds the luminescent film 21 to the keycap 40. The luminescent film 21 is similar to... Figure 3 The second adhesive layer 32 has a thickness of no more than 0.035 mm, preferably no more than 0.03 mm, and is preferably transparent to allow light to pass through.
[0049] Please see Figure 5 In another preferred embodiment of the present invention, the luminescent component 20C has two layers of luminescent films 21 stacked on top of each other and a first adhesive layer 30. The two luminescent films 21 have a first surface (i.e., the bottom surface) and a second surface (i.e., the top surface) located on opposite sides. The first adhesive layer 30 is disposed on the first surface (bottom surface) of the two luminescent films 21, so that the luminescent component 20C is bonded to the keycap 12. The use of a multi-layer luminescent film structure can further improve the luminescence brightness and the continuous luminescence time.
[0050] Please see Figure 6 The luminescent component 20D of another preferred embodiment of the present invention has a plurality of luminescent films 21 stacked on top of each other, a first adhesive layer 30 and a second adhesive layer 32. The plurality of luminescent films 21 have a first surface (i.e., the bottom side surface) and a second surface (i.e., the top side surface) located on opposite sides. The first adhesive layer 30 is disposed on the first surface of the plurality of luminescent films 21 to bond the luminescent component 20D to the keycap 12, and the second adhesive layer 32 is disposed on the second surface (top side surface) of the plurality of luminescent films to bond the luminescent component 20D to the key film 40. Figure 5 and Figure 6 The same as the luminous film Figure 3 The luminescent film. The two adhesive layers 30 and 32 of the luminescent components 20B and 20D can be made of the same or different materials. It is preferable that the second adhesive layer 32 is transparent so that light can pass through.
[0051] The first adhesive layer 30 of the aforementioned luminous components 20A~20D can be made white or light-colored, which can increase the luminous brightness of the luminous film 21. The light color is a color with higher brightness according to the color theory.
[0052] Please see Figure 7This is another preferred embodiment of the luminescent component 20E of the present invention. The luminescent component 20E of this preferred embodiment can be any of the luminescent components shown in the above embodiments. In this embodiment, luminescent particles 22 are added to the first adhesive layer 30, which can improve the overall luminescence brightness of the luminescent component 20. The adhesive layer 30 is preferably transparent, and the amount of luminescent particles 22 therein is less than that in the luminescent film 21, so as to avoid affecting the adhesion performance of the adhesive layer.
[0053] According to the ISO / DIS 17398 standard for luminescence, the brightness of luminescent powder is divided into seven levels, A to G, with G being the highest. According to the ISO's D-level standard, the luminescence of the luminescent material must reach 35 lumens (mcd / m²) after one hour of emission. 2 According to the ISO Class B standard, the luminescence of a luminous material must reach 7 lumens after 1 hour of emission, while the Class C standard requires a luminescence of 20 lumens after 1 hour of emission. According to the inventors' tests, the luminous film 21 with a thickness of 0.022 mm of this invention has a luminescence of over 35 lumens after 1 hour of emission, meeting the ISO Class D standard, which is sufficient to allow the luminous buttons of this invention to be used for more than one hour in the absence of light; the luminous film 21 with a thickness of 0.016 mm of this invention has a luminescence of over 20 lumens after 1 hour of emission, meeting the ISO Class C standard, and can meet the usage requirements for more than 2 hours.
[0054] The key film 40 can be a single-layer film or a multi-layer film. The key film 40 can be a polymer film, a metal film or a film of other materials. Any film that can cover the key cap 12 can be used as the key film of the present invention. Any film that can be molded by a mold can be used as the key film. Figure 11 In the preferred embodiment shown, the bonding membrane 40 (40A) is a single-layer membrane; Figure 8 In the preferred embodiment shown, the bonding membrane 40 is a double-layer membrane, comprising an outer layer 41 and an inner layer 42, and is manufactured as follows: Figure 8 As shown, two layers of resin are sequentially coated on a release film 50 to form a polymer film. After the polymer film hardens and sets, it separates from the release film 50 to form a bonding film 40 with an outer layer 41 and an inner layer 42. The surface 52 of the release film 50 can be textured to give the outer surface 411 of the outer layer 41 a textured appearance, which can increase the tactile feel and anti-slip effect between the fingers and the outer surface of the outer layer 41.
[0055] In this embodiment, the outer layer 41 and the inner layer 42 are made of thermoplastic polymers. Preferably, the outer layer 41 is made of polycarbonate polyurethane to provide excellent physical and mechanical properties, and is resistant to hydrolysis, heat, abrasion, oxidative degradation and weathering; the inner layer 42 is made of thermoplastic polyurethane, which is elastic and easy to stretch and shape.
[0056] Figure 8The membrane is cut to an appropriate size and can be molded into... Figure 2 The key membrane 40 is used to cover single-key buttons and can also be molded into... Figure 14 The key membrane 70 is used to cover multiple keys. The thickness of the key membrane is preferably between 0.03mm and 0.1mm to avoid affecting the key feel.
[0057] Please see Figure 2 The key membrane 40 is shaped into an upwardly convex hollow cover, the shape and size of which correspond to the keycap 12 of the key 10, and has a top wall 43 and a peripheral wall 44 extending downward from the top wall 43.
[0058] Please see Figure 1 In this embodiment, the luminescent component 20A is adhered to the top surface 13 of the keycap 12 by the first adhesive layer 30, making the keycap a luminescent keycap; the key film 40 covers the keycap 12 and encloses the luminescent component 20A inside. The inner surface of the key film 40 is bonded to the top side of the luminescent component 20A and the peripheral surface 14 of the keycap 12 with an adhesive 45, such as hot melt adhesive, thermosetting adhesive or other adhesive. The luminescent component 20A is located between the top wall 43 of the key film 40 and the top surface 13 of the keycap 12, and its top side and bottom side are respectively bonded to the key film 40 and the top surface 13 of the keycap 12; the peripheral wall 44 of the key film 40 is bonded to the peripheral surface 14 of the keycap 12.
[0059] A perforated portion 46 is provided on the top wall 43 of the key film 40, exposing the luminescent component 20 to the perforated portion 46, including direct or indirect exposure. The perforated portion 46 is formed by removing material from the key film 40 using a laser engraving process, becoming the display character of the key 10, such as letters, numbers, symbols, etc., through which the luminescence of the luminescent film 21 can pass. In this embodiment, the perforated portion 46 penetrates multiple layers of the key film 40, such as... Figure 1 As shown, or through a single-layer bond membrane 40, such as Figure 11 As shown, the luminescent component 20 is directly exposed to the perforated portion 46. The outer layer 41 of the key film 40 is a colored opaque material. Except for the perforated portion 46, the luminescence of the luminescent component is blocked by the key film 40 and only shines through from the character position, resulting in high recognizability.
[0060] In this embodiment, the luminescent component 20A of the button 10A is directly exposed to the perforated portion 46, allowing the luminescence of the luminescent film 21 to be emitted from the perforated portion 46, thus making the button glow. The luminescent component 20A is located inside the key film 40, preventing it from being touched, falling off, or wearing down, thus maintaining the long-term stability of the luminescent function of the button 10.
[0061] Figure 1 , Figures 9 to 11An embodiment of a single-key luminous button 10 is not manufactured by in-mold injection or vacuum molding. Instead, the keycap 12, luminous component 20, and key film 40 are first manufactured separately. The key film 40 is then shaped into a covering, the luminous component 20 is attached to the keycap 12, and the key film 40 is then used to cover the luminous component 20 and the keycap 12 to form the luminous button 10.
[0062] Example 2 Please see Figure 9 The difference between this embodiment and Embodiment 1 is that the luminescent component adopts a double-layer luminescent film structure 20C. The perforated portion 46 penetrates the outer layer 41 of the bonding film 40 but does not penetrate the inner layer 42. The laser engraving depth only reaches but does not penetrate the inner layer 42, so the laser engraving will not damage the luminescent component 20C. The inner layer 42 and the adhesive 45 are transparent, and the luminescent component 20C is indirectly exposed to the perforated portion 46. The luminescence of the two luminescent films 21 can penetrate the adhesive 45 and the inner layer 42 and be emitted from the perforated portion 46. The rest of the structure of this embodiment is the same as that of Embodiment 1.
[0063] Specifically, Figure 9 This is a cross-sectional view of the key 10 of the second preferred embodiment of the present invention, which includes: a keycap 12, a key foot 15, a luminescent component 20 (20C), a key membrane 40, and a perforated portion 46. The keycap 12 and... Figure 1 As shown, the luminous component 20 (20C) is bonded to the top surface 13 of the keycap 12 by the first adhesive layer 30, and the inner surface of the key film 40 is bonded to the top side surface of the luminous component 20 (20C) and the peripheral surface 14 of the keycap 12 by a transparent adhesive 45. The luminous component 20 (20C) is... Figure 5 As shown in the embodiment, it is located between the top wall 43 of the key film 40 and the top surface 13 of the keycap 12. The perforated portion 46 penetrates the outer layer 41 of the key film 40 but does not penetrate the inner layer 42. The inner layer 42 and the adhesive 45 are transparent, and the luminescent component 20 (20C) is indirectly exposed to the perforated portion 46. The luminescence of the two luminescent films 21 can penetrate the adhesive 45 and the inner layer 42 and be emitted from the perforated portion 46.
[0064] Example 3 Please see Figure 10 The difference between this embodiment and Embodiment 2 is that the luminescent component uses 20E luminescent particles added to the first adhesive layer, resulting in higher overall brightness. The luminescent particles in the two luminescent films 21 and the first adhesive layer 30 emit light together, and the luminescence can penetrate the adhesive 45 and the inner layer 42, emitting light from the perforated portion 46. The remaining structure of this embodiment is the same as that of Embodiment 2.
[0065] Specifically, Figure 10This is a cross-sectional view of the key 10 according to the third preferred embodiment of the present invention, comprising: a keycap 12, a key foot 15, a luminescent component 20 (20E), a key membrane 40, a perforated portion 46, and an adhesive 45. The keycap 12, the key membrane 40, the perforated portion 46, and the adhesive 45 are integrated with... Figure 9 As shown, the inner surface of the key film 40 is bonded to the top side of the luminous component 20 (20E) and the peripheral surface 14 of the keycap 12 with a transparent adhesive 45.

Figure 7 As shown in the embodiment, the luminescence of the two luminescent films 21 of the luminescent component 20E can penetrate the adhesive 45 and the inner layer 42 and be emitted from the perforated portion 46.
[0066] Example 4 Please see Figure 11 The difference between this embodiment and Embodiment 1 is that the key film 40 is a single-layer plastic film, and its inner surface is bonded to the top side of the luminous component 20 and the peripheral surface 14 of the keycap 12 with a transparent adhesive 45. The perforated portion 46 penetrates the single-layer key film 40. The luminous component 20 can be... Figure 3 , Figure 5 or Figure 7 The luminescent components 20A, 20C, or 20E shown emit their luminescence from the open portion 46. The remaining structure of this embodiment is the same as that of Embodiment 1.
[0067] Specifically, Figure 11 The key 10 of the fourth preferred embodiment of the present invention includes: a keycap 12, a key foot 15, a luminous component 20, a key membrane 40, and a perforated portion 46. The key membrane 40 is a single-layer membrane, and its inner surface is bonded to the top side of the luminous component 20 and the peripheral surface 14 of the keycap 12 with a transparent adhesive 45. The luminous component 20 can be... Figure 3 , Figure 5 or Figure 7 The luminescent components 20A, 20C, or 20E shown have their luminescence emitted from the open portion 46.
[0068] Example 5 Please see Figure 12In this embodiment, the button 10 is a single-key luminous button, comprising a keycap 12, a key foot 15, a luminous component 20, a key membrane 40, and a perforated portion 46. The luminous component 20 is adhered to the top surface 13 and peripheral surface 14 of the keycap 12 by the first adhesive layer 30. Next, the keycap 12 with the luminous component 20 attached is placed into the mold cavity, and the key membrane 40 is injection molded, so that the key membrane 40 is formed on the outer surface of the luminous component 20 in the mold cavity and directly bonded to the outer surface of the luminous component 20. Then, the perforated portion 46 is made, which completely penetrates the single or multiple layers of the key membrane 40. When the key membrane 40 is multi-layered, the perforated portion 46 can penetrate the outer layer 41 but not the inner layer 42.
[0069] This embodiment is manufactured using an in-mold injection molding process. The key film 40 does not require an adhesive and can be directly bonded to the luminous component 20, resulting in higher bonding strength and a more stable structure. This embodiment can also be manufactured using an in-mold vacuum forming method. First, the luminous component 20 is adhered to the top surface 13 and peripheral surface 14 of the keycap 12, and the key film 40 is fabricated before it is shaped. Next, the keycap 12 with the luminous component 20 attached and the key film 40 are placed into a mold cavity, and the mold cavity is evacuated. This allows the key film 40 to be shaped in the mold cavity and directly cover the luminous component 20 and bond to its outer surface. Then, the perforated portion 46 is fabricated.
[0070] Specifically, Figure 12 This is a cross-sectional view of the button 10 according to the fifth preferred embodiment of the present invention. It is a single-key luminous button, comprising: a keycap 12, a key foot 15, a luminous component 20, a key membrane 40, and a perforated portion 46. The key membrane 40 may be a single-layer or multi-layer membrane, and the luminous component 20 may be... Figure 3 , Figure 5 or Figure 7 The luminescent components 20A, 20C, or 20E are shown. The key 10 is manufactured using in-mold injection molding. First, the luminescent component 20 is adhered to the top surface 13 and peripheral surface 14 of the keycap 12 using the first adhesive layer 30. Next, the keycap 12 with the luminescent component 20 attached is placed into the mold cavity, and the key film 40 is injection molded, forming the key film 40 on the outer surface of the luminescent component 20 within the mold cavity and directly bonding it to the outer surface. Then, the perforated portion 46 is formed, completely penetrating one or more layers of the key film 40. When the key film 40 is multi-layered, the perforated portion 46 penetrates the outer layer 41 but not the inner layer 42. Through in-mold injection molding, the key film 40 can be directly bonded to the luminescent component 20 without the need for adhesives.
[0071] Figure 12The key 10 can also be manufactured by in-mold vacuum forming. First, the luminous component 20 is adhered to the top surface 13 and peripheral surface 14 of the keycap 12 with the first adhesive layer 30, and the key membrane 40 is made, but not yet shaped. Next, the keycap 12 with the luminous component 20 attached and the key membrane 40 are placed into a mold cavity, and the mold cavity is evacuated, so that the key membrane 40 is shaped in the mold cavity and directly covers the luminous component 20 and bonds to the outer surface of the luminous component 20. Then, the perforated portion 46 is made. With this manufacturing method, the key membrane 40 can be directly bonded to the luminous component 20 without the need for adhesive.
[0072] Example 6 Please see Figure 13 In this embodiment, the key 10 is a single-key luminous key, comprising a keycap 12, a key foot 15, a luminous film 21, a key membrane 40, and a perforated portion 46. The luminous film 21 is disposed on the top surface 13 and the peripheral surface 14 of the keycap 12, and the luminous film 21 forms a top surface 26 and a peripheral surface 28; the key membrane 40 is bonded to the outer surface of the luminous film 21, including bonding to the top surface 26 and the peripheral surface 28 of the luminous film.
[0073] In this embodiment, the luminous film 21 and the keycap 12 can be manufactured by in-mold injection molding. First, the luminous film 21 is manufactured and shaped to fit the shape of the keycap. The shaped luminous film is placed into a mold cavity, and then the keycap 12 is injection molded from plastic material, allowing the keycap 12 to directly bond with the luminous film 21 within the mold cavity. The luminous film 21 covers the top surface 13 and peripheral surface 14 of the keycap 12. Then, the perforated portion 46 is manufactured. With this manufacturing method, no adhesive is needed between the luminous film 21 and the keycap 12.
[0074] The structure of this embodiment can also be combined using an in-mold vacuum forming method. First, the luminous film 21 and the keycap 12 are made, but the luminous film 21 is not yet shaped. The keycap 12 and the luminous film 21 are placed into a mold cavity, and the mold cavity is evacuated, so that the luminous film 21 is shaped in the mold cavity and directly covers and bonds to the outer surface of the keycap 12. Then, the perforated portion 46 is made. In this method, no adhesive is needed between the luminous film 21 and the keycap 12.
[0075] The bonding film 40 covers the outer surface of the luminescent film 21, and the two can be formed in three ways: first, the bonding film 40 is bonded to and covers the luminescent film 21 with a transparent adhesive; second, the bonding film 40 is bonded to the outer peripheral surface of the luminescent film 21 by in-mold injection molding; and third, the bonding film 40 is bonded to the outer peripheral surface of the luminescent film by in-mold vacuum forming.
[0076] Example 7 Please see Figure 14 and Figure 15 The luminescent button 60 provided in this embodiment is an example of a plurality of buttons. For example, it makes a plurality of (all or some) buttons of a button module 80 luminescent buttons; that is, it is a multi-button combination luminescent button structure applied to the button module 80, including a housing 81, a plurality of buttons 60, a plurality of luminescent components 20B, and a key membrane 70. The frame 82 of the housing 81 forms a plurality of button holes 84, and the keycap 12 of each button 60 is exposed from the corresponding button hole. Each luminescent component 20B is... Figure 4 The luminescent components shown have a first adhesive layer 30, a luminescent film 21, and a second adhesive layer 32. These luminescent components 20B are adhered to the top surface 13 of the keycaps 12 by the first adhesive layer 30. Figure 14 and Figure 16 As shown.
[0077] The bonding membrane 70 can be a single-layer or multi-layer membrane. Taking a multi-layer membrane as an example, the bonding membrane consists of... Figure 8 Made of a polymer film, including a colored opaque outer layer 41 and a transparent inner layer 42, the key film 70 is molded into a plurality of upwardly protruding hollow covering parts 72 to match the buttons 60 of the key module 80. Adjacent covering parts 72 are connected by a bridging part 75. Covering parts 72 at different positions can have different sizes to match different buttons. Each covering part 72 has a top wall 73 and a peripheral wall 74.
[0078] A plurality of perforated portions 76 are respectively provided on the top wall 73 of the covering portions 72 to form characters of the key 60. The perforated portions 76 can penetrate the key film 70 so that the luminous member 20B is exposed to the perforated portion 76; alternatively, the perforated portions 76 can penetrate the outer layer 41 of the key film 70, but not the inner layer 42.
[0079] The key film 70 covers some or all of the keys 60 of the key module 80 with the covering portions 72. In this preferred embodiment, the covering portions 72 of the key film 70 cover all the keys of the key module 80. Each luminous component 20B is located between the top surface 13 of each keycap 12 and the top wall 73 of each covering portion 72. The top surface 13 of the keycap 12 is bonded by the first adhesive layer 30, and the top wall 73 of the covering portion 72 is bonded by the second adhesive layer 32. The luminescence of the luminous component 20B can be transmitted through the open portion 76, causing the keys to emit luminescence. The inner layer 42 and the second adhesive layer 32 are transparent and will not block or hinder the luminescence of the luminous film 21. The peripheral wall 74 of each covering portion 72 covers the peripheral surface 14 of each keycap 12. No adhesive is used to bond the peripheral wall 74 of the covering portion 72 to the peripheral surface 14 of the keycap 12, maintaining the flexibility and freedom of the peripheral wall 74. The bridging portion 75 of the key membrane 70 is bonded to the frame 82 of the housing 81 with an adhesive layer 78, such as hot melt adhesive, thermosetting adhesive, or other adhesive, so that the key membrane 70 is disposed on the top surface of the key module 80. The key membrane 70 covers the entire key module 80, thus creating a waterproof keyboard.
[0080] The luminous component 20B of each key 60 emits light through the perforated portion 76, causing the key to glow. Since the peripheral wall 74 of the covering portion 72 is not bonded to the peripheral surface 14 of the keycap 12, when the key 60 is pressed, the peripheral wall 74 is not affected by the adhesive and can freely flex and deform and recover without affecting the vertical movement of the key 60. The key membrane 70 is thin, extensible, and flexible, making it easy to press the key 60. The outer layer 41 of the key membrane 70 is wear-resistant, allowing the key to be used for a long time without wear on the characters (perforated portions). The luminous component 20B is located inside the key membrane 70, preventing it from falling off or being touched, thus maintaining the long-term stability of the key 60's luminous function.
[0081] Figure 14 and Figure 18 The multiple luminous key embodiments shown are not manufactured by in-mold injection or in-mold vacuum forming. Instead, the keycap 12, luminous component 20 and key film 70 are first manufactured separately, the key film 70 is shaped into a covering part 72, the luminous component 20 is attached to the keycap 12, and then the key film 70 is used to cover the luminous component 20 and the keycap 12 to form the luminous key 60.
[0082] Example 8 Please see Figure 18The difference between this embodiment and Embodiment 7 is that the luminous component adopts a multi-layer luminous film structure 20D, having a first adhesive layer 30, two luminous films 21, and a second adhesive layer 32, resulting in higher luminous brightness. The luminous component 20D is adhered to the top surface 13 of the keycaps 12 by the first adhesive layer 30, and to the top wall 73 of the covering portion 72 by the second adhesive layer 32. The luminous light from the luminous component 20D can pass through the transparent portion 76, causing the keys to emit luminous light. The remaining structure of this embodiment is the same as that of Embodiment 7.
[0083] Specifically, Figure 18 This is the eighth preferred embodiment of the luminescent key 60 of the present invention, which is an embodiment of multiple keys, including: multiple keys 60, a key membrane 70, and multiple luminescent components 20. Each key 60 is a key of a key module 80, having a keycap 12 and a key foot 15. The key membrane 70 has multiple covering portions 72 and multiple open portions 76, respectively provided on the top wall 73 of the covering portions 72 to form the characters of the key. The covering portions 72 of the key membrane 70 respectively cover the keycaps 12 of the keys 60. The peripheral wall 74 of each covering portion 72 and the peripheral surface 14 of each keycap 12 are not bonded together with any adhesive, allowing the peripheral wall 74 to be freely flexed and recover. The bridging portion 75 of the key membrane 70 is bonded to the frame 82 of the key module 80 with an adhesive layer 78. Each luminous component 20 (20D) is located between the top surface 13 of each keycap 12 and the top wall 73 of each covering portion 72, and is therefore... Figure 6 The luminescent components shown have a first adhesive layer 30, two luminescent films 21, and a second adhesive layer 32. The luminescent components 20 (20D) are adhered to the top surface 13 of the keycaps 12 by the first adhesive layer 30, and to the top wall 73 of the covering portion 72 by the second adhesive layer 32. The luminescence of the luminescent components 20 (20D) can be transmitted through the perforated portion 76, causing the keys to emit luminescence. The inner layer 42 and the second adhesive layer 32 are transparent and will not block or hinder the luminescence of the luminescent films 21.
[0084] Example 9 Please see Figure 19 This embodiment is an in-mold injection molded multi-key luminous button structure, and the luminous component 20 of each button 60 can be... Figure 3 , Figure 5 or Figure 7The luminous components 20A, 20C, or 20E shown are each adhered to the top surface 13 and peripheral surface 14 of the keycap 12 by the first adhesive layer 30, and each luminous component thus forms a top surface 26 and a peripheral surface 28. The keycap covered with the luminous component 20 forms a luminous keycap, and the top surface 26 and peripheral surface 28 of the luminous component 20 become the top surface and peripheral surface of the luminous keycap. A plurality of transparent adhesives 77 are respectively disposed on the top surface 26 of the luminous component, that is, on the top surface of the luminous keycap. The key module 80 is placed in a cavity, and its frame 82 is coated with an adhesive layer 78. The key film 70 is injection molded to form a plurality of covering portions 72, which respectively cover the luminous keycaps of a plurality of keys 60. The top wall 73 of each covering portion 72 is connected to the top surface 26 of each luminous keycap through adhesives 77. The bridging portion 75 of the key film 70 is bonded to the frame of the key module 80 by the adhesive layer 78. The peripheral wall 74 of each covering portion 72 is not bonded to or attached to the peripheral surface 28 of each luminous keycap, allowing the peripheral wall 74 to be freely flexed and recover. The peripheral surface 28 of the luminous component can be coated or coated with a non-adhesive material, so that the peripheral wall 74 of each covering portion 72 will not bond to or attach to the peripheral surface 28 of the luminous component. Therefore, the covering portion 72 will not affect the pressing sensitivity, recovery, and response of the key 60. The luminescence of the luminous component can be emitted outward from the opening portion 76.
[0085] Example 10 Please see Figure 20 The difference between this embodiment and embodiment 9 is that the bonding film 70 is a single-layer structure, and each adhesive 77 can prevent the luminescent component 20 from being damaged by the laser engraving process. The rest of the structure of this embodiment is the same as that of embodiment 9.
[0086] Specifically, Figure 20 This is a plurality of luminous buttons 60 in the tenth preferred embodiment of the present invention, wherein the luminous component 20 of each button 60 may be... Figure 3 , Figure 5 or Figure 7 The luminous components 20A, 20C, or 20E shown are adhered to the top surface 13 and peripheral surface 14 of the keycap 12 by the first adhesive layer 30, and each luminous component 20 thus forms a top surface 26 and a peripheral surface 28. The key film 70 is molded in an in-mold injection manner to form a plurality of covering portions 72, which respectively cover the luminous keycaps of a plurality of keys 60. The top wall 73 of each covering portion 72 is connected to the top surface 26 of each luminous keycap through each adhesive 77. The bridging portion 75 of the key film 70 is bonded to the frame of the key module 80 by the adhesive layer 78. The peripheral wall 74 of each covering portion 72 is not adhered to or bonded to the peripheral surface 28 of each luminous keycap, so that the peripheral wall 74 can be freely flexed and restored. Figure 20 Button 60 and Figure 19The difference of the key 60 is that the key film 70 is a single layer, and each adhesive 77 can prevent the luminous component 20 from being damaged.
[0087] Example 11 Please see Figure 21 The difference between this embodiment and Embodiment 9 is that the luminous component is only a luminous film 21. Each keycap 12 is bonded to each luminous film 21 by in-mold injection molding or in-mold vacuum molding. Each luminous film 21 is bonded to the top surface 13 and peripheral surface 14 of each keycap 12, and the luminous film forms a top surface 26 and a peripheral surface 28. Thus, the luminous film 21 and the keycap 12 do not need to be bonded by any adhesive or hot melt glue, and the two together form the luminous keycap. The top wall 73 of each covering part 72 is bonded to the top surface 26 of the luminous keycap with adhesive 77, and the bridging part 75 of the key film 70 is bonded to the frame of the key module 80 with the adhesive layer 78. The peripheral wall 74 of each covering part 72 is not bonded to or bonded to the peripheral surface 28 of each luminous keycap, so that the peripheral wall 74 can be freely flexed and recovered. The rest of the structure of this embodiment is the same as that of Embodiment 9.
[0088] Specifically, Figure 21 The button 60 shown in the eleventh preferred embodiment of the present invention has a key film 70 that is injection molded in a mold, which can be... Figure 19 or Figure 20 The structure is as follows. In this preferred embodiment, each luminous component 20 is simply a luminous film 21. Each keycap 12 and each luminous film 21 can be bonded by in-mold injection molding or by in-mold vacuum molding. Each luminous film 21 is bonded to the top surface 13 and the peripheral surface 14 of each keycap 12, and the luminous film forms a top surface 26 and a peripheral surface 28. Thus, the luminous film 21 and the keycap 12 do not need to be bonded by any adhesive or hot melt glue. The luminous film and the keycap 12 form a luminous keycap. The top wall 73 of each covering part 72 is bonded to the top surface 26 of the luminous keycap with adhesive 77, and the bridging part 75 of the key film 70 is bonded to the frame of the key module 80 with the adhesive layer 78. The peripheral wall 74 of each covering part 72 is not bonded to or bonded to the peripheral surface 28 of each luminous keycap, so that the peripheral wall 74 can be freely flexed and restored.
[0089] In summary, in the above embodiments, the first adhesive layer 30 of the luminous component 20 (20A~20E) can be made white or light-colored to serve as a substrate for the luminous component, thereby enhancing the brightness of the luminous component 20 (20A~20E) and improving the luminous brightness of the button.
[0090] The first adhesive layer 30 can be made transparent, while the keycap 12 is made white or light-colored to serve as a substrate for the luminous component, thereby improving the brightness of the luminous component 20 (20A~20E) and the luminous brightness of the key.
[0091] Please see Figure 22 The image shows a luminous keyboard 90 made according to the present invention. Figures 14 to 21 Made in any preferred embodiment, the keyboard keys 60 are covered by the covering portion 72 of the key film 70, and the open portion 76 becomes the character of the key 60. The luminous component of the present invention can absorb and store energy, including the energy that can absorb fluorescent light. In dim light, the luminous film 21 (and the first adhesive layer 30 with luminous particles) will release energy and emit luminescence, making the character (76) glow, and the key 60 becomes a luminous key, which can be identified by the user. With the present invention, the key 60 of the key module can emit luminescence for a long time, and the key can be identified without the use of a backlight module. Eliminating the backlight module can save energy and reduce carbon emissions, and since the backlight module is not used, the power consumption of the computer can be saved, and the usage time of the laptop can be extended when it is not plugged in. All the keys 60 of the keyboard 90 can be luminous keys, or only some of the keys can be luminous keys, which can be flexibly configured according to actual needs.
[0092] The luminous key of the present invention can be used on the keys of various electronic devices to provide a luminous effect and can emit luminescence for a long time, so that the key can emit light without the need for additional power. The keyboards of various electronic devices do not need to use backlight modules, which greatly reduces the energy consumption and production cost of the devices.
[0093] The key membrane and luminescent component of this invention are thin and do not affect the operation of the keys. The key membrane 70 can be made of polyurethane, which is soft and elastic. When the key is pressed, the two adjacent covering parts 72 will not pull on each other, allowing the user to press the key easily.
[0094] The luminescent component 20 is located within the key membranes 40 and 70, preventing it from being touched, falling off, or wearing down, thus maintaining structural integrity. Users will not touch the luminescent component when pressing the buttons, resulting in a comfortable tactile experience.
[0095] In summary, this invention fundamentally solves many of the shortcomings of existing luminous buttons through the modular design of independent luminous components. It combines excellent luminous effect, long service life, good tactile feel and stable mechanical performance, and can achieve continuous luminous display without additional power supply, thus having extremely high industrial application value.
