Description

Technical Field

[0001] The present invention mainly provides a wall electrical panel device with decorative effect, which is particularly suitable for electrical accessory equipment such as wall switches and sockets. Background Art

[0002] The term "wall electrical accessory device" referred to in this article refers to products in the field of building electrical and electrical engineering, including lighting switches, power sockets, alarm devices, etc. Because they meet the standards for building electrical accessories and the long-term usage habits of building users and fixed safety and reliability, improvements on such wall-mounted devices have been widely used. For example, the structure and appearance design of lighting switches and socket equipment have been continuously optimized and stabilized. At present, wall-mounted equipment may use metal coatings, glass and other materials for decorative purposes, or spray colors on the surface to better integrate into the home decoration environment, but such panel devices are expensive and have high manufacturing costs, and spray colors are not conducive to the heat dissipation of the electrical accessory device (especially smart panels, etc.) itself and require frequent surface cleaning. Summary of the invention

[0003] The present invention intends to solve the above-mentioned defects and strives to provide an improved design of the internal structure of the panel itself to achieve an aesthetic effect, especially to provide a beautifying prompt effect under the setting of providing internal outward light emission, so as to improve the user experience without significantly increasing the cost.

[0004] Technical Solution 1: A wall decoration panel, used for installation on a wall electrical accessory to provide an operating surface, comprising a light-transmissive first layer (1), the first layer having a preset thickness and provided with 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 curvature radii, and the first recess (16) surrounds an area where electrical functional parts of the wall electrical accessory are provided.

[0005] As an improvement, the wall decoration panel also includes a second layer board (2) laminated with the first layer board (1), the second layer board (2) being provided with a convex portion (11) having a configuration matching the first concave portion (16) of the first layer board (1), wherein the second layer board (2) and the first layer board (1) have different light transmittances.

[0006] On this basis, an improvement is made, in which a plurality of dispersed convex portions (11) are spliced ​​together and integrally applied to at least the bottom surface (103) of the first concave portion (16) to cover it.

[0007] Furthermore, the second layer plate (2) has a boss (20) having a configuration matching that of the first recess (16), and the projection (11) is laminated and sandwiched between the boss (20) and the first recess (16).

[0008] In the above improved solution, the protrusion (11) is configured as an electric induction component to sense external electric signals. Preferably, the protrusion (11) connects the electric signal to the built-in function board (31) of the wall electrical accessory through one or more conductive contacts (223) provided on the second layer board (2) to be received and identified.

[0009] Furthermore, the function board (31) drives an LED light source (311) arranged on the function board to emit light of different modes according to the recognized type of the electrical signal.

[0010] In the above improved solution, the front surface (15) of the first layer board (1) is provided with one or more second recesses (101) corresponding to the area where the electrical functional parts of the wall electrical accessories are provided for user touch input.

[0011] Technical Solution 2: An intelligent electrical accessory device, comprising a base (3) and the above-mentioned wall decoration panel fixed to the base (3) to provide an operation 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), wherein the power board (32) is used to introduce building power and convert it into driving and regulating power for an LED light source (311) arranged on the function board (31), and light of different modes emitted by the LED light source (311) is incident on the wall decoration panel through a light guide structure to produce different light effects.

[0012] As an improvement, the light-guiding structure includes one or more of the following: a light-guiding hole (221) opened on a lining plate (22) for enclosing the inner cavity (30); a light-transmitting hole (201) penetrated through the second layer plate (2); and / or an isolation light-guiding plate (21) added to the lining plate (22).

[0013] The technical solution provided above has significant advantages: the wall decoration panel of the present invention can present an aesthetic effect as a whole by designing a unique light-guiding, scattering or transmission structure without significantly increasing the current decorative panel structure or using high-end materials to manufacture the panel type, and can produce different light and shadow effects according to the different modes (brightness / color temperature, color or flicker, etc.) emitted by the built-in LED light source of the electrical accessory device according to preset or custom programming logic. In particular, for intelligent electrical accessory devices, different light effects can be transmitted according to different setting modes, and can also be used as a night light when the electrical function of the electrical accessory is not in use. It is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 2 yes Figure 1 A schematic longitudinal section of such a wall decoration panel, in which an example is depicted the improved structure according to the present invention;

[0016] Figure 3 It is a schematic structural explosion diagram of a preferred embodiment of the wall decoration panel of the present invention. DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are fully embodied in the form of comparative descriptions with reference to the accompanying drawings, wherein the same components may be provided with different marks 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 decoration panel of the present invention is depicted in a more vivid way and expressed by means of front and back contrast. This wall decoration panel has a light-transmissive first layer 1, which allows users to directly touch its front surface 15 as a wall decoration panel, so when used in a wall socket or electrical switch, it does not need to be set as a metal surface to avoid electric shock. Preferably, a surface electrostatic treatment film spraying process can also be used to optimize the touch. Figure 1 In the embodiment, the first layer board 1 forms a first concave portion 16 inward from the rear surface 10. Since the first layer board 1 is made of a transparent or translucent light-transmitting material, light incident from any surface of the first layer board 1 can be refracted in the first concave portion 16, so that the first layer board 1 has a more noticeable curved appearance after being assembled to the wall electrical accessory device. Figure 1 The dotted line in the front view shows a kind of raised "bubble" shape.

[0018] As an optimization, the concave portion has a bottom surface 103 and a curved surface 102 extending outward from the bottom surface 103, wherein the bottom surface 103 can be set as a flat surface, so as to facilitate the placement of electronic components related to wall device functions on the flat surface, such as buttons, electrical sockets or indicator devices, etc. Alternatively, the bottom surface 103 can also be manufactured to have a larger curvature radius than the curved surface 102 to appear flatter.

[0019] On this basis, the first concave portion 16 may have a preset thickness and be formed as a coating 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 concave portion 16 with a lower light transmittance may appear more prominent in the inner contour of the translucent first layer 1. In addition, any suitable fine pattern may be doped or sprayed in the coating layer to increase the aesthetics.

[0020] Figure 1 , Figure 2 Another embodiment is also shown. The wall decoration panel of the present invention is also provided with a second layer board 2 attached to the first layer board 1, and the second layer board 2 is used to be fixed on the wall electrical accessory device. For example, the second layer board 2 also has a convex portion (or pasting layer) 11 with a configuration matching the first concave portion 16 of the first layer board 1 to replace the thickened inner surface of the first concave portion 16 itself. In other words, the surface of the first concave portion 16 does not need to be designed with any processing layer with lower light transmittance, but is replaced by the convex portion 11, and because of the assembly method of stacking / inlaying the convex portion, the user can change the pattern or color therein to change the decorative style. In other embodiments, the convex portion can also be arranged as a combined structure, for example, a capacitive sensing layer can be embedded therein to sense the user's touch status.

[0021] The front surface 15 may be provided with one or more second recesses 101 for the user to contact and press or plug in the plug for use, so the bottom surface of the second recess 101 is provided with electrical components such as switch contacts and electrical sockets. The purpose of this design is to take into account the numerical relationship between the thickness of the first and / or second layer and the effective electrical contact distance. The designer found that in some implementation schemes, it is necessary to add a second layer to significantly enhance the obvious effect of this light-guiding design, because under the premise that the area of ​​the wall device is constrained, the larger the thickness, the larger the volume of the whole participating in the light guide, and the more obvious and beautiful the overall outline of the convex part 11 is. However, it cannot affect the electrical characteristics of the wall device itself, such as the effective contact area of ​​the jack for plugging in electricity. In addition, although the second layer 2 can also be formed using transparent or translucent materials, it has greater rigidity and lower light transmittance than the first layer 1, so that the other parts of the rear surface 10 except the first recess 16 can also be arranged to have a certain light reflection effect. Moreover, according to the above embodiment, the second layer 2 is used to be fastened and installed on the wall device, and a buckle part 204 can be provided on its inner side for disassembly and assembly.

[0022] Figure 2The use example of this wall decoration panel is schematically depicted. According to the above-mentioned embodiment, the high light transmittance area of ​​the first layer board 1 is expressed by the shaded part, and the bottom is the first recessed part 16, and the forward lighting circuit can be provided by the function board 31 arranged on the rear surface of the second layer board 2. For example, one or more LED light sources 311 can be used to project light (beam) 341 to the first and second layers of the first layer board 1 and emit it to the external environment after refraction. Preferably, a convex part 11 of a certain size can be attached to the surface of the first recessed part 16, and in this embodiment, the convex part 16 can be set as a capacitive sensing layer to sense the finger of the user 6 or the point-clicking action of the capacitive pen through the relatively thin bottom surface 103 area of ​​the first layer board 1. The second recessed part 101 can be designed with a larger diameter for user contact. In this scheme, the area blocked by the finger contact of the user 6 is smaller than the area where the LED light is transmitted, so the user can more conveniently observe the optical feedback signal of the point-clicking action by the function board 31 around his finger. For example, when the user 6 presses one of the buttons on the front surface 15, only a certain area around the button produces light and shadow changes. In addition, a conductive contact 223 is provided on the second layer board 2 to connect the electrical signal to the sensor or controller on the function board 31 for receiving and identification.

[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 the preferred assembly method for integrating the above-mentioned wall decoration panel into the electrical component. According to the above embodiment, the first layer 1 and the second layer 2 stacked on each other are fixedly mounted on the surface of the base 3 as the user's operating surface. The base 3 is embedded in the building wall and fixed and obtains the building power through the terminal 322 on the power board 32. The building power may not only be a zero-live wire (L / N) but also include other power buses, such as the RS485 bus for carrier-based control of air conditioners, the PoE dimming bus for controlling low-voltage lighting appliances, or the Home-bus protocol bus for controlling other household appliances. The inner cavity 30 of the base 3 is used to install the power board 32 to convert the building power into the power or control level signal required by the function board 31. This is because when used as a dimming switch, it is necessary to continuously output the control electrical signal to trigger the stepless dimming command to the remote lighting device.

[0024] As an optimization solution, the power board 32 and the function board 31 can be connected by a conductive connector 321 (or any inter-board connector element) to achieve electrical conductivity and transmit control electrical signals at the same time. For example, the controller 312 on the function board 31 identifies the sensed point-clicking to generate electrical capacitance to trigger the magnetic latching relay 323 and other electrical switch elements on the power board 32 to act. And the controller 312 triggers one or more LED light sources 311 arranged on the function board 31 to emit light or provide light and shadow indications (such as flashing, color changes, etc.) to prompt the user according to the feedback switch on-off signal. In addition, this light and shadow indication can be pre-programmed or customized (for example, when used alone as a smart night light function) to the controller 312 to produce corresponding light effects according to different clicks or operations of the panel by the user.

[0025] In addition, in order to realize the functional control of the night light, the power circuit 324 on the power board 32 is re-improved to realize the current adjustment of the LED light source 311. For example, a boost circuit can be set for the LED light source 311 array or in parallel according to the type, characteristics and / or lumen level of the LED light source. The power circuit 324 is also divided into multiple branches to power other components on the function board 31, such as the controller 312, wired / wireless communication modules (not shown in the figure), etc. For example, the controller 312 can use a local area network (LAN) similar to a Wi-Fi network and / or point-to-point communication (for example, low-power Bluetooth B-LE) to communicate with an external smart device or receive setting instructions.

[0026] The function board 31 and the power board 32 are assembled and connected to each other and fixed in the inner cavity 30 and covered by the lining plate 22. For example, the cover plate 31 can position each circuit board by fasteners (for example, screws, fixing columns, etc.). A metal conductive contact 223 (or contact pin) extends from the lining plate 22 (preferably the central position) as an insulating pad to the position of the protrusion 11, so that when the protrusion 11 is used as a capacitive sensing layer, it is coupled to the electrical contact 313 through the conductive contact 223 to transmit one or more capacitance signals. To this end, one or more through holes 222 for inserting the conductive contact 223 are provided on the lining plate 22.

[0027] Preferably, the lining plate 22 is also provided with one or more light guide holes 221, the shape of which can be recessed at a certain slope in the direction toward the inner cavity 30, so that the lining plate 22 has a preset thickness and the light guide hole 221 abuts against the position of the LED light source 311 on the functional board 31 to avoid light leakage.

[0028] On this basis, an isolation light guide plate 21 can be added between the backing plate 22 and the second layer plate 2 to guide the LED light. The isolation light guide plate 21 can be made of transparent or translucent PC material. And the isolation light guide plate 21 can be used to support and position between the backing plate 22 and the second layer plate 2.

[0029] The front surface of the second layer 2 is provided with a boss 20, and the surface of the boss 20 has a certain curvature radius to match the configuration of the rear surface of the first layer 1. Therefore, one or more protrusions 11 can be stacked or embedded between the boss 20 and the first concave portion 16 of the first layer 1. In a preferred example, the protrusion 11 can be manufactured into a standard specification part (such as Figure 3 As depicted) so that a corresponding protrusion 11 can be embedded in button positions of different numbers or shapes.

[0030] According to the above embodiments, it can be known that the convex portion 11 can adopt the currently commonly used transparent capacitor plate, or in other embodiments, an opaque metal mesh film can be used to sense electric variables (such as pyroelectric human body presence sensing signals, proximity sensing signals and other micro-motion signals). In this case, a light-transmitting hole 111 with the same or similar shape as the above-mentioned light-guiding hole 221 is also opened on each convex portion 11. In this embodiment, a light-transmitting hole 201 is also opened at a corresponding position on the second layer board 2 (or a light-guiding structure can also be designed separately) so that the LED light is mainly directed to the surrounding of each second concave portion 101 to form a "halo".

[0031] In the above-mentioned embodiments, since the electrical accessory device itself is installed as a wall electrical device, when describing its specific structure or electronic function, the direction toward the outside of the building wall is generally referred to as "front / outside" and the opposite direction is referred to as "back / inside", and when describing a part of the structure, the front, back and other positional relationships are also described in this direction. For example, the light emitting direction of the LED light source 311 is also expressed as "forward". In some embodiments, "mounted on..." sometimes actually also means mounted on its surface and should not be misunderstood as an upward / downward position. "Area" represents a readable, identifiable effective area or volume portion of an electronic function. For example, when a finger is used to touch a capacitive conductive sheet, the description of its area usually refers to any effective position that is randomly touched and includes a portion of the area around it. Therefore, the feature "second recess 101" may be designed to be larger in order to have a larger contact area.
