Description

Technical Field

[0001] This utility model relates to the field of electrical switches, and in particular to an intelligent scene switch with an engraved light-transmitting structure. Background Technology

[0002] With the rapid development of the smart home industry, smart scene switches, as core components connecting various smart devices and enabling scene-based control, are receiving increasing attention for both their functionality and aesthetics. In daily use, smart scene switches need to meet users' operational needs in low-light environments (such as at night). Therefore, they are usually designed with a light-transmitting structure, using a built-in light source to illuminate the functional characters and patterns on the switch surface, allowing users to quickly identify and operate the switch. At the same time, the visual effect of the light-transmitting structure also directly affects the switch's aesthetics and must match the style of the home environment.

[0003] Currently, the light-transmitting structure of smart switches on the market is mainly achieved in the following ways: First, by laser marking to remove part of the light-blocking layer on the surface of the substrate to form a light-transmitting area. However, if the marking depth is not properly controlled, there will be problems such as insufficient light transmission or excessive damage to the substrate, which will affect the service life of the switch. Third, a light-transmitting structure is formed by mold in one piece, and characters are formed by the difference in light transmittance of the substrate itself. However, this method requires high precision of the mold, has high production cost, and is difficult to achieve light-transmitting design of complex patterns. The light-blocking effect is also often not ideal.

[0004] In addition, the existing smart switch designs focus more on basic control and give less consideration to creating an atmosphere. Some switches with ambient lights also have the aforementioned problem of light leakage in their ambient light transmission structure, which fails to meet users' needs for home scene decoration and reduces the user experience.

[0005] Therefore, the aforementioned problems with existing smart scene switches have become urgent issues that need to be addressed in the industry. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent scene switch with a carved light-transmitting structure that has a clear light-transmitting outline, reliable light-blocking effect, strong decorative effect, and stable structure.

[0007] To achieve the above objectives, this utility model adopts the following solution: a smart scene switch with an engraved light-transmitting structure, comprising a button assembly mounted on a switch base box, the surface of which is provided with light-transmitting luminous characters for providing decorative illumination in low-light environments and facilitating user identification and operation of the switch; a middle frame located below the button assembly on the switch base box, and a PCB assembly fixed to the back of the middle frame, the front of which integrates several sets of backlight LED beads; a button light-transmitting component made of a transparent substrate mounted on the middle frame at a position corresponding to the luminous characters of the button assembly, wherein the surface of the button light-transmitting component is covered with a first light-shielding paint layer, the first light-shielding paint layer is provided with a first light-transmitting area, the first light-shielding paint layer at the first light-transmitting area is removed by engraving to expose the transparent substrate, thereby allowing the light from the backlight LED beads to pass through the first light-transmitting area from the luminous characters of the button assembly.

[0008] The above solution uses a button light-transmitting component made of a transparent substrate and covered with a first light-shielding paint layer. The first light-shielding paint layer in the first light-transmitting area is removed by engraving to expose the transparent substrate. Compared with laser marking, engraving is easier to control the damage to the substrate, avoiding the problems of insufficient light transmission or excessive damage to the substrate affecting its lifespan. Compared with mold-integrated molding, engraving does not rely on high-precision molds, which can realize the light-transmitting design of complex text and patterns, and reduce production costs. This achieves the basic effect of clear light-transmitting outline and reliable light-shielding effect. At the same time, the light from the backlight LED beads shines through the first light-transmitting area from the illuminated characters of the button component, meeting the recognition and operation needs in low-light environments.

[0009] As a further embodiment of this invention, the first light-transmitting area is the same outline of text, pattern, or symbol as the illuminated characters of the button assembly. A first light-shielding paint layer surrounding the first light-transmitting area completely covers the substrate, forming a light-shielding boundary without light leakage. This solution addresses the problem of "light leakage at character edges and blurred light-shielding boundaries" by precisely matching the first light-transmitting area with the fully covered light-shielding boundary, completely preventing light leakage and making the illuminated characters clearer and more aesthetically pleasing, thus improving operational recognition and decorative appeal.

[0010] As a preferred embodiment of this utility model, an ambient light assembly is further provided on the middle frame. This ambient light assembly includes a translucent substrate disposed on the middle frame and a second light-shielding paint layer covering the surface of the translucent substrate. The second light-shielding paint layer has a second light-transmitting area. The second light-shielding paint layer at the second light-transmitting area is removed by carving to expose the transparent substrate, thereby allowing the light from the backlight LED beads on the PCB assembly to pass through the second light-transmitting area. The ambient light assembly in this embodiment, by covering the surface of the translucent substrate with a second light-shielding paint layer and carving to form the second light-transmitting area, solves the problems of light leakage and monotonous shape in existing ambient light switches. The carving process allows for flexible design of the second light-transmitting area as linear or geometric shapes, breaking through the limitations of traditional ambient light shapes and meeting the diverse needs of users for home scene decoration. Simultaneously, the boundary formed by the second light-shielding paint layer and the carving effectively blocks light leakage, ensuring a more orderly and aesthetically pleasing presentation of the ambient light rays.

[0011] As a further embodiment of this utility model, the second light-transmitting area is a linear or geometrically shaped light-transmitting area provided along the surface of the middle frame.

[0012] As a preferred embodiment of this utility model, the first light-shielding paint layer and the second light-shielding paint layer are spray paint layers or screen printing layers, which ensures the uniformity of the light-shielding layer and provides a stable foundation for accurate light transmission after engraving.

[0013] As a preferred embodiment of this utility model, the transparent substrate of the button light-transmitting component is made of silicone.

[0014] As a preferred embodiment of this utility model, the translucent substrate of the ambient light assembly is made of acrylic or PC material.

[0015] The above solution uses silicone for the button backlight component and acrylic or PC for the ambient light component, which improves both light transmission performance and component durability.

[0016] As a preferred embodiment of this utility model, the PCB assembly is provided with a wireless communication module including a Mesh smart chip and a Bluetooth communication interface, which enriches the linkage control function of the smart scene switch and enhances the intelligent attributes of the product.

[0017] As a further embodiment of this invention, mounting slots are provided on the middle frame at the positions corresponding to the illuminated characters of the button components. The light-transmitting button components are embedded in the mounting slots. Several fixing posts are spaced apart around the mounting slots on the back of the middle frame. A protruding mounting platform is provided around the bottom of the light-transmitting button components, and the mounting platform has insertion holes for the fixing posts. This solution specifically solves the problem of "unstable connection between the light-transmitting components and other parts," ensuring that all components are tightly assembled, avoiding changes in the light transmission path due to loosening, guaranteeing the stability of the light transmission effect, and further improving the user experience.

[0018] As a further embodiment of this utility model, the button assembly includes at least one switch panel, and a back plate for connecting and supporting the switch panel is provided below the switch panel. A receiving hole is provided through the back plate at the position corresponding to the button light-transmitting component, and the receiving hole allows the light from the button light-transmitting component to pass through to the preset luminous characters on the switch panel. The connection structure consists of a hook provided on the back of the back plate and a slot provided on the middle frame. The hook passes through the corresponding slot and hooks onto the back of the middle frame.

[0019] In summary, the advantages of this utility model compared to the prior art are as follows: Firstly, by setting a transparent substrate button light-transmitting component with a first light-shielding paint layer covering its surface, and by using an engraving method to remove the light-shielding layer in the first light-transmitting area, this utility model precisely solves the problems of uneven light transmission, light leakage, and blurred light-shielding boundaries in existing light-transmitting structures. At the same time, it avoids substrate damage caused by improper control of laser marking depth. Compared with mold-in-one molding, it is easier to achieve light-transmitting designs for complex text or patterns, and it significantly reduces production costs. Furthermore, by making the first light-transmitting area consistent with the outline of the illuminated characters on the button component, and by ensuring that the surrounding light-shielding layer completely covers the substrate, the sealing of the light-shielding boundary is further strengthened, completely preventing light leakage, making the illuminated characters clearer, and improving the operational recognition in low-light environments.

[0020] In addition, by setting a semi-transparent substrate ambient light component with a second light-blocking paint layer in the middle frame, and combining it with a second light-transmitting area formed by carving linear or geometric shapes, the problems of light overflow and monotonous form of existing ambient light switches are solved, enriching the decorative effect of home scenes and enhancing the decorative nature of the product.

[0021] Secondly, the cooperation between the middle frame mounting slot, the fixing post and the button light-transmitting component mounting platform and the socket, as well as the connection structure between the back plate hook and the middle frame slot, effectively solves the problem of unstable connection between the light-transmitting component and other components, ensuring a stable light transmission path and avoiding fluctuations in the light transmission effect; at the same time, the wireless communication module on the PCB component enhances the product's intelligent linkage capability and adapts to diverse intelligent scene control needs.

[0022] Therefore, this utility model achieves a comprehensive effect of clear light transmission outline, reliable light blocking effect, strong decorative effect, stable structure and reasonable cost, which significantly improves the user experience and home adaptability.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 7 The smart scene switch with an engraved light-transmitting structure shown includes a switch base box 10, a PCB assembly 3, a middle frame 2, an ambient light assembly 21 and a button light-transmitting assembly 5 disposed on the middle frame 2, and a button assembly 1 mounted on the switch base box 10. The button assembly 1 includes at least one switch panel 11 and a back plate 12 for connecting and supporting the switch panel 11. The surface of the switch panel 11 is provided with light-transmitting luminous characters, which serve to achieve a decorative effect by emitting light in low-light environments, while also facilitating users to quickly identify the switch function and operate it. The back plate 12 has a receiving hole 13 through it at the position corresponding to the button light-transmitting assembly 5. The receiving hole 13 is used for the light transmitted by the button light-transmitting assembly 5 to pass through, so that the light can reach the preset luminous characters on the switch panel 11, ensuring that the luminous characters can be evenly illuminated.

[0034] It should be noted that the middle frame 2 is installed on the switch base box 10 below the button assembly 1. The middle frame 2 not only serves to support and connect the various components, but also provides an installation base for the ambient light assembly 21 and the button light-transmitting assembly 5. The button assembly 1 and the middle frame 2 are fixed by a connection structure, which consists of a hook 14 on the back of the back panel 12 and a slot 25 on the middle frame 2. The hook 14 passes through the corresponding slot 25 and hooks onto the back of the middle frame 2. This hook and slot cooperation structure enables quick assembly and stable connection between the button assembly 1 and the middle frame 2, ensuring a stable positional relationship between the two and preventing the light transmission to the illuminated characters from being affected by loose assembly.

[0035] Mounting slots 23 are provided on the middle frame 2 at the positions corresponding to the illuminated characters of the button assembly 1. These mounting slots 23 are used to embed the button light-transmitting components 5. Through precise slot size design, the position of the button light-transmitting components 5 is ensured to be stable after installation, avoiding the deviation of the light transmission path due to shaking. At the same time, a number of fixing posts 24 are provided at intervals around the mounting slots 23 on the back of the middle frame 2, and a protruding mounting platform 52 is provided around the bottom of the button light-transmitting components 5. The mounting platform 52 has a socket 53 that can accommodate the fixing posts 24. When the button light-transmitting components 5 are embedded in the mounting slots 23, the fixing posts 24 are inserted into the corresponding sockets 53. The interference fit between the posts and the holes achieves a tight connection between the button light-transmitting components 5 and the middle frame 2, effectively solving the problem of unstable connection between the light-transmitting components and other components, ensuring a stable light transmission path, and avoiding fluctuations in the light transmission effect due to loosening.

[0036] The PCB assembly 3 is fixed to the back of the middle frame 2. The front of the PCB assembly 3 integrates several sets of backlight LED beads 31, which are respectively set to the button light-transmitting assembly 5 and the ambient light assembly 21 to provide light source for both. At the same time, the PCB assembly 3 is also equipped with a wireless communication module 4 containing a Mesh smart chip and a Bluetooth communication interface. This module can realize wireless linkage between the switch and other smart devices, enrich the control function of the smart scene switch, enhance the intelligent attributes of the product, and meet the user's needs for diverse smart scene control.

[0037] The light-transmitting component 5 of the button is installed on the middle frame 2 at the position corresponding to the luminous character of the button component 1. The light-transmitting component 5 of the button is made of a transparent substrate, preferably silicone. Silicone not only has good light transmission performance, but also has good flexibility and durability, and can adapt to long-term pressing operation. The surface of the button light-transmitting component 5 is covered with a first light-shielding paint layer 111. The first light-shielding paint layer 111 is a spray paint layer or a screen printing layer. This process can ensure the uniformity of the light-shielding layer and provide a stable foundation for accurate light transmission after subsequent engraving. The first light-shielding paint layer 111 is provided with a first light-transmitting area 51. The first light-transmitting area 51 is the same text, pattern or symbol outline as the luminous characters of the button component 1. The first light-shielding paint layer 111 at the corresponding position is removed by engraving process to expose the transparent substrate. Compared with laser marking, the engraving method is easier to control the damage to the substrate and avoids the problem of insufficient light transmission or excessive damage to the substrate affecting the lifespan. At the same time, compared with mold one-piece molding, it does not need to rely on high-precision molds, making it easier to realize the light transmission design of complex text or patterns and reducing production costs. The first light-shielding paint layer 111 around the first light-transmitting area 51 completely covers the substrate, forming a light-shielding boundary without light leakage, which completely avoids the problem of light leakage at the edge of the character and blurring of the light-shielding boundary, making the display of the luminous characters clearer and more beautiful.

[0038] In addition, such as Figures 2 to 7 As shown, the ambient light assembly 21 is disposed on the middle frame 2. The ambient light assembly 21 includes a translucent substrate disposed on the middle frame 2 and a second light-shielding paint layer 211 covering the surface of the translucent substrate. The translucent substrate is preferably acrylic or PC. Both materials are uniformly translucent and have excellent mechanical properties, ensuring soft ambient light and durable components. The second light-shielding paint layer 211 is also a spray-painted or screen-printed layer, ensuring uniform light shielding. The second light-shielding paint layer 211 has a second light-transmitting area 22, which is a linear light-transmitting area set along the surface of the middle frame 2, specifically located on one side of the edge of the button component 1. The second light-shielding paint layer 211 at the corresponding position is removed by an engraving process to expose the translucent substrate. The flexibility of the engraving process allows for more free design of the shape of the second light-transmitting area 22, breaking through the limitations of the traditional single shape of ambient lights and meeting the diverse needs of users for home scene decoration. At the same time, the boundary formed by the second light-shielding paint layer 211 and the engraving can effectively block light leakage, ensuring that the ambient light is presented in a more orderly and beautiful manner, solving the problem of light leakage in existing ambient light switches.

[0039] Through the cooperation of the above components, the light from the backlight LED beads 31 can pass through the first light-transmitting area 51 of the button light-transmitting component 5 and the receiving hole 13 of the back plate 12, and then pass through the illuminated characters of the button component 1. At the same time, the light from the corresponding backlight LED beads 31 can also pass through the second light-transmitting area 22 of the ambient light component 21, achieving a comprehensive effect of clear light transmission outline, reliable light shielding effect, strong decorative effect and stable structure.

[0040] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
