Description

Technical Field

[0001] This utility model mainly provides a decorative wall electrical panel device, which is especially suitable for electrical accessories such as wall switches and sockets. Background Technology

[0002] The term "wall-mounted electrical accessories" used in this article refers to products in the field of building electrical engineering, including lighting switches, power outlets, alarm devices, etc. Because they conform to building electrical accessory standards and meet the long-term usage habits and fixed safety and reliability requirements of building users, improvements to these wall-mounted devices have been widely applied. For example, the structure and shape design of lighting switches and outlet devices have been continuously optimized and stabilized. Currently, wall-mounted devices used for decorative purposes may utilize materials such as metal coatings and glass, or have their surfaces painted to better integrate into the home décor. However, such panel devices are expensive and have high manufacturing costs. Furthermore, the painted surfaces are not conducive to heat dissipation of electrical accessories (especially smart panels) and require frequent surface cleaning. Utility Model Content

[0003] This utility model aims to solve the above-mentioned defects and strives to provide an improved design of the internal structure of the panel to achieve an aesthetic effect, especially to provide an aesthetic prompt effect under the setting of providing internal outward light emission, so as to improve the user experience without significantly increasing costs.

[0004] Technical Solution 1: A wall decorative panel for installation on a wall electrical accessory to provide an operating surface, comprising a light-transmitting first layer (1), the first layer having a predetermined thickness and having a first recess (16) from a rear surface (10) to a front surface (15), wherein the first recess (16) has a bottom surface (103) and a curved surface (102) extending outward from the bottom surface, the bottom surface (103) and the curved surface (102) having different radii of curvature, and the first recess (16) surrounds the area where the electrical functional components of the wall electrical accessory are located.

[0005] As an improvement, the wall panel further includes a second layer (2) that is laminated to the first layer (1). The second layer (2) has protrusions (11) with a configuration matching the first recess (16) of the first layer (1), wherein the second layer (2) and the first layer (1) have different light transmittances. Further improvements include splicing multiple dispersed protrusions (11) together and applying them integrally to at least the bottom surface (103) area of ​​the first recess (16) to cover it.

[0006] Furthermore, the second layer plate (2) has a boss (20) with a configuration matching the first recess (16), the boss (11) being stacked and sandwiched between the boss (20) and the first recess (16).

[0007] In the above improved scheme, the protrusion (11) is configured as an inductive component to sense external electrical signals. Preferably, the protrusion (11) connects the electrical signals to the built-in functional board (31) of the wall electrical accessory through one or more conductive contacts (223) passing through the second layer plate (2) for reception and recognition.

[0008] Furthermore, the functional board (31) drives the LED light source (311) arranged on the functional board to emit different modes of light according to the identified electrical signal category.

[0009] In the above improved scheme, the front surface (15) of the first layer plate (1) is provided with one or more second recesses (101) corresponding to the location of the electrical functional component of the wall electrical accessory for user access input.

[0010] Technical Solution 2: A smart electrical accessory device, comprising a base (3) and the aforementioned wall decoration panel fixed on the base (3) to provide an operating surface, wherein a power board (32) and a function board (31) electrically connected thereto are arranged in the inner cavity (30) of the base (3), the power board (32) is used to introduce building power and convert it into driving and regulating power for LED light sources (311) arranged on the function board (31), and different modes of light emitted by the LED light sources (311) are incident into the wall decoration panel through a light guide structure to produce different light effects.

[0011] As an improvement, the light guide structure includes one or more of the following: a light guide hole (221) opened on the liner (22) used to seal the inner cavity (30); and a light transmission hole (201) passing through the second layer plate (2).

[0012] And / or an isolation light guide plate (21) added to the liner (22).

[0013] The above-mentioned technical solutions have significant advantages: the wall decorative panel of this utility model can achieve an overall aesthetic effect by designing a unique light guiding, scattering, or transmission structure without significantly increasing the structure of current decorative panels or using high-end materials to manufacture the panel type. Moreover, it can produce different light and shadow effects according to the different modes (brightness / color temperature, color, or flashing, etc.) of the built-in LED light source of the electrical accessory device according to preset or custom programming logic. Especially for intelligent electrical accessory devices, it can transmit different light effects according to different setting modes. It can also be used as a night light when the electrical function of the electrical accessory is not used, which is worth promoting. Attached Figure Description

[0014] Figure 1 is a three-dimensional structural diagram showing the front and back of the wall decorative panel provided by this utility model.

[0015] Figure 2 is a longitudinal cross-sectional schematic diagram of the wall decorative panel of Figure 1, in which an example is depicted to illustrate an improved structure based on the present invention;

[0016] Figure 3 is an exploded view of a preferred embodiment of the wall decorative panel of this utility model. Detailed Implementation

[0017] The preferred embodiment of this utility model is illustrated in detail by way of accompanying drawings. The same components may be marked differently in different drawings for the purpose of separate description, but this does not affect the presentation of the technical solution. Figure 1 The outer surface structure of the wall decorative panel of this utility model is illustrated in a relatively vivid way, and is expressed by front and back contrast. This wall decorative panel has a light-transmitting first layer 1, which, as a wall decorative panel, allows the user to directly touch its front surface 15. Therefore, when used in wall sockets or electrical switches, it is not necessary to make it a metal surface to avoid electric shock. Preferably, a surface electrostatic thin film spraying process can also be used to optimize the tactile feel. In the embodiment of FIG1, the first layer 1 forms a first recess 16 from the rear surface 10 inward. Because the first layer 1 is made entirely of a transparent or translucent light-transmitting material, light entering from any surface of the first layer 1 can be refracted in the first recess 16, thus giving the first layer 1 a more prominent curved appearance after it is assembled into a wall electrical accessory. That is, a raised "foam" shape as shown by the dotted lines in the front view of FIG1.

[0018] As an optimization, the recess has a bottom surface 103 and a curved surface 102 extending outward from the bottom surface 103, wherein the bottom surface 103 can be made flat to facilitate the placement of electronic components related to wall-mounted devices, such as buttons, electrical sockets, or indicators. Alternatively, the bottom surface 103 can also be manufactured with a larger radius of curvature than the curved surface 102 to appear even flatter.

[0019] Based on this, the first recess 16 may have a preset thickness and be formed as an adhesive layer with a lower light transmittance than the main material of the first layer 1. Therefore, when the wall decoration panel is installed, the first recess 16 with lower light transmittance will appear more prominent against the inner contour of the translucent first layer 1. In addition, any suitable small patterns may be mixed or sprayed into the adhesive layer to enhance its aesthetics.

[0020] Figures 1 and 2 also illustrate another embodiment. The wall decorative panel of this invention further includes a second layer 2 attached to the first layer 1, which is used to fix to a wall electrical accessory device. For example, the second layer 2 also has a protrusion (or adhesive layer) 11 with a configuration matching the first recess 16 of the first layer 1, replacing the thickened inner surface of the first recess 16 itself. That is, the surface of the first recess 16 does not need to be designed with any processing layer with lower light transmittance, but is replaced by the protrusion 11. Furthermore, because of the stacking / embedding assembly method of the protrusion, users can change the patterns or colors to vary the decorative style. In other embodiments, the protrusion can also be configured as a modular structure, for example, a capacitive sensing layer can be embedded therein to sense the user's touch state.

[0021] The front surface 15 may be provided with one or more second recesses 101 to facilitate user contact for pressing or plugging in electrical components. Therefore, electrical components such as switch contacts and electrical sockets are provided on the bottom surface of the second recesses 101. This design aims to balance the numerical relationship between the thickness of the first and / or second layers and the effective electrical contact distance. Designers found that in some implementations, adding a second layer significantly enhances the light-guiding effect because, given the limited area of ​​the wall device, a greater thickness results in a larger overall volume involved in light guiding, making the overall outline of the protrusion 11 more prominent and aesthetically pleasing. However, this must not affect the electrical characteristics of the wall device itself, such as the effective contact area for plugging in electrical components. Furthermore, while the second layer 2 can also be made of transparent or translucent material, it has greater rigidity and lower light transmittance than the first layer 1, allowing the rear surface 10, excluding the first recess 16, to also have a certain light-reflective effect. Furthermore, according to the above embodiment, the second layer plate 2 is used for fastening on the wall device, and a buckle part 204 can be provided on its inner side to realize disassembly and assembly.

[0022] Figure 2 schematically depicts an example of the use of this wall panel. As described in the aforementioned embodiment, the high light transmittance area of ​​the first layer 1 is represented by a shaded portion, the bottom of which is the first recess 16, which can be illuminated by a functional board 31 disposed on the rear surface of the second layer 2. For example, one or more LED light sources 311 can be used to project light (beams) 341 into the first and second layers 1 and then outwards to the external environment after refraction. Preferably, a protrusion 11 of a certain size can be attached to the surface of the first recess 16, and in this embodiment, the protrusion 16 can be configured as a capacitive sensing layer to sense the tapping action of the user 6's finger or capacitive pen through the relatively thin bottom surface 103 area of ​​the first layer 1. The second recess 101 can be designed with a larger diameter for easy user contact. In this scheme, the area blocked by the user 6's finger contact is smaller than the area through which the LED light is transmitted, so the user can more easily observe the optical feedback signal of the tapping action by the functional board 31 around their finger. For example, when user 6 presses one of the buttons on the front surface 15, only a certain area around that button will experience a change in light and shadow. Furthermore, conductive contacts 223 are mounted on the second layer 2 to connect electrical signals to sensors or controllers on the function board 31 for recognition.

[0023] Figure 3 Based on the above implementation scheme, a specific embodiment of an electrical accessory device is provided. Figure 3 The main functional components of the accessory device are described in detail, including a preferred assembly method that integrates the aforementioned wall panel into the electrical components. According to the above embodiment, the first layer 1 and the second layer 2, stacked on top of each other, are fixedly mounted on the surface of the base 3 to serve as the user's operating surface. The base 3 is embedded in the building wall and obtains building power through the terminal block 322 on the power board 32. The building power may not only be live and neutral (L / N) wires but also include other power buses, such as an RS485 bus for carrier-based control of air conditioners, a PoE dimming bus for controlling low-voltage lighting appliances, or a Home-bus protocol bus for controlling other household appliances. The inner cavity 30 of the base 3 is used to house the power board 32 to convert the building power into the power or control level signals required by the functional board 31. This is because when used as a dimming switch, continuous output of control electrical signals is required to trigger stepless dimming commands to remote lighting equipment.

[0024] As an optimization, the power board 32 and the function board 31 can be connected via a conductive connector 321 (or any inter-board connector element) to achieve electrical conductivity and simultaneously transmit control signals. For example, the controller 312 on the function board 31 identifies and senses a touch, generating capacitance to trigger an electrical switching element such as a magnetic latching relay 323 on the power board 32. Furthermore, the controller 312, based on the feedback switch on / off signal, triggers one or more LED light sources 311 arranged on the function board 31 to emit light or provide light and shadow indicators (e.g., flashing, color changes, etc.) to prompt the user. Moreover, this light and shadow indicator can be pre-programmed or customized (e.g., when used alone as a smart night light function) to the controller 312 to produce corresponding lighting effects according to different touches or operation methods of the user on the panel.

[0025] Furthermore, to enable functional control of the night light, the power supply circuit 324 on the power board 32 has been redesigned to adjust the current of the LED light source 311. For example, depending on the type, characteristics, and / or lumen rating of the LED light source, a boost circuit can be configured to supply power to the LED light source 311 array, or they can be configured in parallel. The power supply circuit 324 also has multiple branches to power other components on the functional board 31, such as the controller 312 and wired / wireless communication modules (not shown in the figure). For example, the controller 312 can use a local area network (LAN) similar to Wi-Fi and / or point-to-point communication (e.g., Bluetooth Low Energy B-LE) to communicate with external smart devices or receive setting commands.

[0026] After the functional board 31 and the power board 32 are assembled and connected to each other, they are fixed in the inner cavity 30 and covered by the liner 22. For example, the liner 22 can be used to position the various circuit boards by fasteners (such as screws, fixing posts, etc.). A conductive metal contact 223 (or pin) extends from the liner 22, which serves as an insulating pad, to the protrusion 11, thereby coupling conductivity through its contact 112 when the protrusion 11 is used as a capacitive sensing layer, and coupling to the electrical contact 313 through the conductive contact 223 to transmit one or more capacitance signals. For this purpose, one or more through holes 222 are provided on the liner 22 for inserting the conductive contact 223.

[0027] Preferably, the liner 22 is also provided with one or more light guide holes 221. The shape of such light guide holes can be recessed at a certain slope in the direction towards the inner cavity 30. Therefore, the liner 22 has a preset thickness and the light guide holes 221 abut against the position of the LED light source 311 on the functional board 31 to avoid light leakage.

[0028] Based on this, an insulating light guide plate 21 can be added between the liner 22 and the second layer plate 2 to guide the LED light. The insulating light guide plate 21 can be made of transparent or semi-transparent PC material. Furthermore, the insulating light guide plate 21 can serve as a support and positioning element between the liner 22 and the second layer plate 2.

[0029] The front surface of the second layer plate 2 is provided with a boss 20, and the surface of the boss 20 has a certain radius of curvature to match the configuration of the rear surface of the first layer plate 1. Therefore, one or more protrusions 11 can be stacked or inlaid between the boss 20 and the first recess 16 of the first layer plate 1. In a preferred example, the protrusions 11 can be manufactured as standard-sized parts (like... Figure 3 (Depicted in that way) so that a corresponding protrusion 11 can be embedded in the position of buttons of different numbers or shapes.

[0030] As can be seen from the above embodiments, the protrusion 11 can be a commonly used transparent capacitor plate, or in other embodiments, an opaque metal mesh can be used to sense electrical variables (such as pyroelectric signals, proximity signals, and other micro-motion signals). In this case, a light-transmitting hole 111 with the same or similar shape as the light guide hole 221 is also opened on each protrusion 11. In this embodiment, a light-transmitting hole 201 is also opened at the corresponding position on the second plate 2 (or a light guide structure can be designed in another way) so that the LED light is mainly directed to form a "halo" around each second recess 101.

[0031] In the aforementioned implementation schemes, since the electrical accessory device itself is installed as a wall-mounted electrical device, when describing its specific structure or electronic function, the direction facing outwards from the building wall is generally referred to as "front / outer" and the opposite as "back / inner," and the positional relationship such as front and back is also described in this direction when describing a part of its structure. For example, the light emission direction of the LED light source 311 is also expressed as "forward." In some embodiments, "installed on..." actually sometimes means installed on its surface and should not be misunderstood as an upward / downward position. "Area" refers to the readable, identifiable effective area or volume portion of the electronic function. For example, when using a finger to touch the conductive sheet of a capacitor, the area is usually described as any effective location randomly touched and includes a portion of its surrounding area. Therefore, the feature "second recess 101" may be designed to be larger to have a larger contact area.
