Description

Technical Field

[0001] This utility model relates to the field of switches, and more particularly to a European-style intelligent switch. Background Technology

[0002] With the development of smart home technology, smart switches, as an important part of the home electrical control system, are becoming increasingly diversified in function, and the requirements for miniaturization, high integration and ease of installation are also increasing. Traditional wall-mounted smart switches mostly adopt a single-layer circuit board structure, with electronic components concentrated on a single PCB board. This results in problems such as limited wiring space, limited functional expansion, and poor heat dissipation. Especially in the European market, due to the strict restrictions on switch size imposed by building electrical standards (such as DIN 49012), traditional structures are unable to achieve complex control functions and stable electrical connections within a limited space.

[0003] At the same time, due to the tight internal space layout, the product is prone to poor heat dissipation, maintenance difficulties, and even affects the overall operational stability. Therefore, how to optimize the spatial layout of smart switches and improve their internal space utilization has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a European-style smart switch that optimizes internal space and makes the structure more compact by installing two circuit boards between the panel and the base.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a panel, a circuit board module and a base, wherein the panel is located on the rear side of the base and the circuit board module is located between the base and the panel, a switch is rotatably mounted on the panel, and the circuit board module includes a first circuit board and a second circuit board, wherein the second circuit board is located on the rear side of the first circuit board and the first circuit board is located on the rear side of the switch.

[0006] The present invention is further configured to include a mating plate located between the second circuit board and the panel. The second circuit board has a plurality of block-shaped mounting portions protruding rearward. The first circuit board has mounting grooves corresponding to each mounting portion. The mating plate includes abutting sections located on the upper and lower sides of the front end face of the second circuit board. The rear end face of each abutting section abuts against the front end face of the second circuit board.

[0007] The present invention is further configured such that: the first circuit board is provided with a plurality of positioning blocks made of a material that is prone to deformation in the circumferential direction; the mating plate is provided with a positioning slot for each positioning block and a limiting block is provided on the front side of the positioning slot; each positioning block falls into the corresponding positioning slot and the rear end face of the limiting block abuts against the front end face of the corresponding positioning block; the mating plate also includes a mating block located on the rear side of each positioning block.

[0008] The present invention is further configured such that: each of the top positioning blocks includes a front guide surface, and the guide surface is inclined from top to bottom and from back to front.

[0009] The present invention is further configured such that: the first circuit board has two mounting blocks made of a material that is prone to deformation protruding forward and the two mounting blocks are symmetrically arranged; each mounting block includes a fixing section fixed to the first circuit board and a limiting section located behind the corresponding fixing section; the second circuit board has mounting slots corresponding to each mounting block; and the rear end face of each limiting section abuts against the second circuit board.

[0010] The present invention is further configured such that: the second circuit board is provided with mating grooves corresponding to each mounting slot, and each mating groove is interconnected with the corresponding mounting slot and located inside the corresponding limiting segment.

[0011] The present invention is further configured such that: the panel is provided with a groove for inserting a mating plate, the panel is provided with an abutting section in the circumference of the groove that abuts against the mating plate, and the panel is provided with a positioning ridge for inserting a limiting block protruding forward.

[0012] The present invention is further configured such that the positioning rib is arranged in a trapezoidal shape with the area of ​​the front end face being smaller than the area of ​​the rear end face.

[0013] By adopting the above technical solution, since the first circuit board is located in front of the second circuit board, and both the first and second circuit boards are located between the panel and the base, the position setting of the first and second circuit boards makes the layout inside the panel more compact, while providing space for the functional expansion of the smart switch. This design allows more electronic components to be integrated in a limited space. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-9As shown, this utility model discloses a European-style smart switch, including a panel 1, a circuit board module 2, and a base 3. The panel 1 is located behind the base 3, and the circuit board module 2 is located between the base 3 and the panel 1. A switch component 11 is rotatably mounted on the panel 1. The circuit board module 2 is equipped with several electronic components and other functional modules. The base 3 is equipped with several wiring terminals 31. By tightening screws, wires can be clamped to achieve electrical connection, thus providing power to the entire smart switch and directly energizing the circuit board module 2. When it is necessary to turn on an appliance or object linked to the smart switch, the switch component 11 is flipped downwards to generate a signal, thereby executing the command, such as turning on a light or a relay. When the circuit is closed, the load circuit is formed, the lamp is powered on and lit, or the relay is disconnected, the circuit is cut off, and the lamp is turned off (this is existing technology and will not be described in detail here). The circuit board module 2 includes a first circuit board 21 and a second circuit board 22. The second circuit board 22 is located behind the first circuit board 21, while the first circuit board 21 is located behind the switch 11. Since the first circuit board 21 is located in front of the second circuit board 22, and both the first circuit board 21 and the second circuit board 22 are located between the panel 1 and the base 3, the position setting of the first circuit board 21 and the second circuit board 22 makes the layout inside the panel 1 more compact, while providing space for the functional expansion of the smart switch. This design allows more electronic components to be integrated in a limited space.

[0030] The system also includes a mating plate 4 located between the second circuit board 22 and the panel 1. The second circuit board 22 has several block-shaped mounting portions 221 protruding rearward. The first circuit board 21 has mounting grooves 211 corresponding to each mounting portion 221. The mating plate 4 includes abutting sections 41 located on the upper and lower sides of the front end face of the second circuit board 22. The rear end face of each abutting section 41 abuts against the front end face of the second circuit board 22. When the first circuit board 21 and the second circuit board 22 are brought close together, each mounting portion 221 of the second circuit board 22 can enter the mounting groove 211 of the first circuit board 21, thereby determining the relative position of the two. At this time, due to the presence of each mounting portion 221, the first circuit board 21 cannot rotate relative to the second circuit board 22 after connection, thus facilitating the connection and fixation of the two.

[0031] The first circuit board 21 is circumferentially provided with a plurality of positioning blocks 212 made of rubber or other easily deformable materials. The mating plate 4 is provided with a positioning slot 42 corresponding to each positioning block 212, and a limiting block 43 is provided in front of the positioning slot 42. Each positioning block 212 falls into its corresponding positioning slot 42, and the rear end face of the limiting block 43 abuts against the front end face of the corresponding positioning block 212. The mating plate 4 also includes a mating block 44 located behind each positioning block 212. By connecting the first circuit board 21 and the second circuit board 22 together, each positioning block 212 of the first circuit board 21 is inserted into its corresponding positioning slot 42, thereby determining the relative position of the two. However, because each positioning block 212 needs to forcibly pass over the corresponding limiting block 43 during the process of entering its corresponding positioning slot 42, the relative position of the two can be determined. With the two in place, the front side of each positioning plug 212 abuts against the rear end face of the limiting plug 43, and the rear side of each positioning plug 212 abuts against the mating plug 44. Therefore, after assembly, the front and rear sides of the positioning plug 212 of the first circuit board 21 are restricted by the limiting plug 43 and the mating plug 44 respectively, and cannot be offset relative to the mating plate 4, so they can be stably installed together with the mating plate 4. At this time, without the action of external force, the first circuit board 21 can be stably connected to the mating plate 4. At this time, the first circuit board 21 and the second circuit board 22 are already connected together. Therefore, the second circuit board 22 is stably located between the mating plate 4 and the first circuit board 21. At the same time, when it is necessary to separate the mating plate 4 and the first circuit board 21, by applying force to the first circuit board 21, each positioning plug 212 is forced forward to press the corresponding limiting plug 43, thereby realizing the separation of the two.

[0032] Preferably, each of the top positioning blocks 212 includes a rear guide surface 2121. The guide surface 2121 is inclined from top to bottom and from front to back. Due to the presence of the guide surface 2121, during the process of inserting the first circuit board 21 into the mating plate 4, the guide surface 2121 of the positioning block 212 will first contact the limiting block 43. At this time, since the guide surface 2121 is inclined, the area at the top of the positioning block 212 is minimized, which allows it to be aligned with the positioning slot 42 more smoothly and conveniently.

[0033] The first circuit board 21 has two protruding mounting blocks 213 made of easily deformable materials such as rubber, which are symmetrically arranged. Each mounting block 213 includes a fixing section 2131 fixed to the first circuit board 21 and a limiting section 2132 located behind the corresponding fixing section 2131. The second circuit board 22 has mounting slots 222 corresponding to each mounting block 213. The rear end face of each limiting section 2132 abuts against the second circuit board 22. When the circuit board 21 and the second circuit board 22 are connected and assembled, the cooperation between each mounting part 221 and the mounting groove 211 determines their relative positions. At this time, each mounting plug 213 is aligned with the corresponding mounting slot 222. However, since the rear end face of each mounting plug 213 will abut against the second circuit board 22 after it is inserted into the corresponding mounting slot 222, the first circuit board 21 will not separate from the second circuit board 22 under the restriction of each mounting plug 213 without the action of external force, thus making the two stably connected together.

[0034] Preferably, the second circuit board 22 is provided with mating grooves 223 corresponding to each mounting slot 222. Each mating groove 223 is interconnected with the corresponding mounting slot 222 and is located inside the corresponding limiting segment 2132. Since each mating groove 223 is located inside the corresponding limiting segment 2132, when the mounting block 213 on the first circuit board 21 is inserted into the corresponding mounting slot 222, each mounting block 213 needs to be forced towards the mating groove 223 so that the limiting segment 2132 can pass over the mounting slot 222 and thus abut against the second circuit board 22. At this time, without external force, the first circuit board 21 can be stably connected to the second circuit board 22. When it is necessary to separate the first circuit board 21 and the second circuit board 22, the limiting segment 2132 is bent towards the mating groove 223 so that each limiting segment 2132 moves forward through the mating groove 223 and the mounting slot 222, thus completing the separation of the two.

[0035] Furthermore, the panel 1 is provided with a groove 13 for inserting the mating plate 4. The panel 1 is provided with an abutting section 14 in the circumference of the groove 13, which abuts against the mating plate 4. The panel 1 is provided with a positioning ridge 12 for inserting a limiting block protruding forward. When the mating plate 4 is inserted into the groove 13 from front to back, the rear side of the mating plate 4 will abut against the abutting section 14 in the circumference of the panel 1, thereby determining the position of the panel 1 and the mating plate 4 in the front-back direction. At the same time, since the positioning ridge 12 inserts the mating plate 4, the mating plate 4 cannot move up and down or left and right relative to the panel 1. After the switch 11 is connected to the bread by rotation, the mating plate 4 can be stably positioned between the panel 1 and the switch 11.

[0036] Preferably, the positioning rib 12 is arranged in a trapezoidal shape with the area of ​​the front end face smaller than that of the rear end face. Therefore, during the process of inserting the mating plate 4 into the panel 1, since the front end face of each positioning rib will enter the mating plate 4 first, the positioning rib with the front area smaller than the rear area can be more smoothly aligned with the position on the mating plate 4 for insertion, thus facilitating the installation and connection of the two.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
