Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an intelligent switch panel with CAN bus communication. Background Technology

[0002] A wall switch is an electrical switch installed on a wall to connect and disconnect circuits, controlling lighting. In a narrow sense, electrical products usually refer only to switches and sockets in building electrical systems. A common name for a wall switch is a light switch. In a broader sense, electrical products encompass a wider range, generally referring to equipment that provides power and electrical control to end users, including switches, sockets, circuit breakers, structured cabling, security systems, etc., also known as building electrical accessories (a general term for devices used to fix, connect, or switch circuits).

[0003] The applicant disclosed a lighting control panel with RS485 bus communication in patent publication number CN220359403U. The panel includes an embedded housing with a wiring section and an operating section. The wiring section is embedded in a mounting structure and connects to a cable installed within the structure. The housing contains a circuit board, and the cable is connected to the circuit board. A button is provided on the circuit board, corresponding to a push-button on the operating section that is movably connected to the housing. A cover plate is provided on the operating section of the housing, which engages with the housing to secure the circuit board inside. The cover plate has a trigger area, from which the button protrudes. Each trigger area has a lamp opening, allowing light-emitting devices mounted on the circuit board to be exposed. This utility model optimizes the corresponding structure of the push-button, cover plate, and housing. While maintaining the advantages of a contact-type push-button switch, it provides feedback on the current triggered switch state in the form of light. Furthermore, the provided limiting groove cooperates with the ring flange of the push-button to limit its rotation range, preventing excessive rotation from affecting the stability of the button's triggering action. The overall structure of the housing is also optimized for easy disassembly, installation, and maintenance.

[0004] As can be seen from the patent above, although this RS485 bus communication light control panel can provide feedback on the current triggered switch status in the form of light and avoids excessive rotation of the button affecting the stability of pressing the trigger button, and also has the characteristics of convenient disassembly, installation or maintenance, the applicant found that because the trigger element on the cover is a bendable structure formed by the protruding side wall of the mounting position extending into the trigger area, the trigger element is prone to fatigue fracture after long-term use. When the trigger element breaks, it is difficult to provide sufficient elastic support for the button, making the button easy to rotate freely relative to the cover, thus affecting the normal use of the user, reducing the stability of pressing the trigger button, and the manufacturing process of the trigger element is relatively complicated, making it difficult to remanufacture and repair, and shortening its service life. At the same time, because the control panel uses RS485 bus communication, its box contains related structural components such as wiring terminals, which makes the box larger in size, requiring more space considerations during installation, and inconvenient for installation. Utility Model Content

[0005] The main purpose of this utility model is to provide a smart switch panel with CAN bus communication, which aims to solve the problems of existing smart switch panels being prone to affecting normal use by users due to the breakage of the trigger element, reducing the stability of pressing the trigger button, and the relatively complicated manufacturing process of the trigger element, making it difficult to remake and maintain, shortening its service life, and making it inconvenient to install.

[0006] To achieve the above objectives, this utility model provides a smart switch panel with CAN bus communication, including a housing, a cover plate, a button plate, and a circuit board. The bottom of the housing has a groove, and the circuit board is fastened to the opening of the groove. The cover plate is detachably connected to the housing and is used to cover the circuit board. The side of the circuit board facing the groove has wiring terminals, and the bottom of the groove has a through slot for the wiring terminals to extend out. The side of the circuit board away from the groove has several buttons, and the cover plate has trigger holes for the buttons to protrude. The button plate is movably connected to the cover plate, and the side of the button plate facing the cover plate has several support members detachably mounted for contacting the buttons.

[0007] Preferably, each of the support members has an annular flange at the end furthest from the button plate.

[0008] Preferably, the plurality of the support members and the push plate are an integral structure.

[0009] Preferably, the cover plate has a plurality of trigger holes arranged in a rectangular array, the cover plate has a pivot at the center line along its width direction, and the button plate has a card seat that is rotatably connected to the pivot.

[0010] Preferably, an annular barrier for shielding the cover plate is formed on the side of the pressing plate facing the cover plate, and the annular barrier has protrusions at both ends along the width direction of the cover plate.

[0011] Preferably, the top of the box has two ramps, which are symmetrically distributed about the pivot axis, and the two ramps slope downward from the pivot axis toward the button.

[0012] Preferably, the groove opening is provided with a recess for accommodating the circuit board, the circuit board and the cover plate are provided with a plurality of through holes, the plurality of through holes are arranged in a rectangular array, and a plurality of bosses are formed on the box body, the plurality of bosses passing through the plurality of through holes one by one and being detachably connected to the locking member.

[0013] Preferably, a first identifier is provided on the side of the button panel away from the box body and corresponding to the positions of several buttons; a second identifier is provided on the box body corresponding to the positions of the wiring terminals.

[0014] Beneficial effects:

[0015] 1. In the CAN bus communication intelligent switch panel of this utility model, the button is pressed and triggered by a support member that abuts against it. The support member replaces the trigger member of the prior art. The support member only serves to press the button, so there is no need to worry about the support member fatigue and breakage after long-term use, thus extending the service life. Moreover, the elastic restoring force of the button itself can provide elastic support for the support member and the button plate, which can not only effectively prevent the button plate from rotating randomly relative to the cover plate, but also improve the stability and sensitivity of pressing the button plate and triggering the button.

[0016] 2. In the CAN bus communication intelligent switch panel of this utility model, since the support component and the button are detachably connected, it is convenient to disassemble and repair the support component, which is beneficial to manufacturing. There is no need to replace the entire cover plate or button plate during maintenance. Moreover, the support component in this utility model is more durable and reliable than the trigger component, which effectively saves maintenance costs.

[0017] 3. In the CAN bus communication intelligent switch panel of this utility model, signal transmission and power supply can be realized through wiring terminals, so that there is no need to set wiring heads and other related structural components in the box of this utility model, thereby reducing the volume of the box. This not only makes it easier to store, pick up and transport, but also reduces the space occupation and other factors that need to be considered during installation, making installation easier.

[0031] Example 1:

[0032] This utility model proposes an intelligent switch panel with CAN bus communication.

[0033] In one embodiment of this utility model, the CAN bus communication smart switch panel includes a housing 1, a cover plate 2, a button plate 3, and a circuit board 4. A groove 5 is formed at the bottom of the housing 1. The circuit board 4 is fastened to the groove 5. The cover plate 2 is detachably connected to the housing 1 and is used to cover the circuit board 4. The side of the circuit board 4 facing the groove 5 has a wiring terminal 6. The bottom of the groove 5 has a through groove for the wiring terminal 6 to extend out. The side of the circuit board 4 away from the groove 5 has several buttons 7. The cover plate 2 has trigger holes 8 for the buttons 7 to protrude. The button plate 3 is movably connected to the cover plate 2. The side of the button plate 3 facing the cover plate 2 is detachably equipped with several support members 9 for abutting against the buttons 7.

[0034] Specifically, such as Figures 1 to 5 In the CAN bus communication smart switch panel of this utility model, the circuit board 4 is snapped into the groove 5 on the housing 1, and the cover plate 2 is detachably connected to the housing 1, which can securely install and press the circuit board 4 into the housing 1. The detachable connection between the cover plate 2 and the housing 1 can be a threaded connection, which facilitates the disassembly and assembly of the cover plate 2 and the circuit board 4 and is convenient for maintenance. Furthermore, by opening a through groove at the bottom of the groove 5, the wiring terminals 6 on the circuit board 4 can extend from the through groove and connect to the external cable, thereby realizing signal transmission and power supply. The structural design is simple and reasonable. At the same time, since the circuit board 4 has several buttons 7, the cover plate 2 has trigger holes 8 for several buttons 7 to protrude, and the button plate 3 is movably connected to the cover plate 2. The movable connection between the button plate 3 and the cover plate 2 can be a snap-fit ​​connection, that is, the button plate 3 can rotate relative to the cover plate 2 within a certain range. When the user presses the button plate 3, the support member 9 at the corresponding position on the button plate 3 presses down on the corresponding button 7, thereby triggering the switch logic on the circuit board 4. When button 7 on circuit board 4 is triggered, it communicates with external devices (such as lighting systems, control systems, etc.) via the CAN bus communication protocol to control the switch.

[0035] Understandably, in the CAN bus communication smart switch panel of this utility model, the support member 9 abuts against the button 7, and the support member 9 replaces the trigger member of the prior art to press and trigger the button 7. The support member 9 only serves to press the button 7, so there is no need to worry about the support member 9 fatigue breaking after long-term use, thus extending the service life. Moreover, the elastic restoring force of the button 7 itself can provide elastic support for the support member 9 and the button plate 3, which can not only effectively prevent the button plate 3 from rotating freely relative to the cover plate 2, but also improve the stability and sensitivity of pressing the button plate 3 and triggering the button 7. At the same time, since the support member 9 and the button plate 3 are detachably connected, the detachable connection can be a threaded connection, which facilitates the disassembly and maintenance of the support member 9, which is beneficial to manufacturing. There is no need to replace the entire cover plate 2 or button plate 3 during maintenance. Furthermore, the support member 9 in this utility model is more durable and reliable than the trigger member, effectively saving maintenance costs. In addition, since the wiring terminal 6 on the circuit board 4 is connected to the external cable in this utility model, signal transmission and power supply can be realized through the wiring terminal 6. As a result, there is no need to set up wiring heads and other related structural components in the box 1 of this utility model, thereby reducing the volume of the box 1. This not only makes it easier to store, pick up and transport, but also reduces the space occupation and other factors that need to be considered during installation, making installation easier.

[0036] In one embodiment, a plurality of support members 9 have annular flanges formed at the ends of the support members 9 away from the push plate 3. Specifically, as shown in the figure... Figure 1 , Figure 3and Figure 5 As shown, the annular flange increases the contact area between the support 9 and the button 7, thereby further improving the stability and sensitivity of pressing the button plate 3 and triggering the button 7, making it reliable in use.

[0037] In one embodiment, the plurality of support members 9 and the button plate 3 are integrally formed. Understandably, by making the plurality of support members 9 and the button plate 3 into an integral structure, the assembly steps between the plurality of support members 9 and the button plate 3 are omitted, assembly gaps are avoided, assembly errors are eliminated, and it is easy to produce and manufacture. For example, the plurality of support members 9 and the button plate 3 can be directly injection molded using a mold, and the structural design is simple and reasonable.

[0038] In one embodiment, a plurality of trigger holes 8 are arranged in a rectangular array on the cover plate 2, and a rotating shaft 10 is provided at the center line of the cover plate 2 along its width direction. A retaining seat 11 rotatably connected to the rotating shaft 10 is formed on the pressing plate 3. Specifically, as shown... Figure 1 , Figure 3 and Figure 5 As shown, since several trigger holes 8 are arranged in a rectangular array on the cover plate 2, users can trigger corresponding switch commands, such as turning on corridor lights or room lights, by pressing the area of ​​the button 3 corresponding to a specific trigger hole 8. Furthermore, due to the rotatable connection between the pivot 10 and the card holder 11, not only can the button 3 rotate smoothly when subjected to external force, but it can also prevent the button 3 from falling off or shaking during rotation. The structural design is simple and reasonable. At the same time, the buttons 7 located on both sides of the pivot 10 can provide elastic support for the button 3, so that when the user does not press the button 3, the button 3 is in a position relatively parallel to the cover plate 2. The user can intuitively see the position of each switch, making it easier to find and trigger the required switch command, thus improving the convenience of use.

[0039] In one embodiment, an annular barrier 12 for shielding the cover plate 2 is formed on the side of the cover plate 3 facing the cover plate 2, and protrusions 13 are formed at both ends of the annular barrier 12 along the width direction of the cover plate 2. Specifically, as shown in the figure... Figures 3 to 5 As shown, the annular barrier 12 shields the cover plate 2, preventing external impurities and liquids from entering the circuit board 4 and causing damage, thus extending its service life and improving the stability of the button plate 3 during rotation. Furthermore, because the annular barrier 12 has protrusions 13, when the button plate 3 rotates relative to the cover plate 2, the protrusions 13 prevent the button plate 3 from rotating excessively or deviating from its predetermined trajectory, thereby helping to maintain the stability and accuracy of the button plate 3 during rotation, ensuring reliable use.

[0040] In one embodiment, the top of the housing 1 has two ramps 14, which are symmetrically distributed about the pivot 10 as the center line, and the two ramps 14 slope downward from the pivot 10 toward the button 7. Specifically, as shown... Figure 3 As shown, the two ramps 14 on the top of the box 1 allow users to experience a more comfortable and natural tactile feedback when operating the button 3, and it is also more aesthetically pleasing and practical.

[0041] In one embodiment, a recess 15 for accommodating the circuit board 4 is provided at the opening of the groove 5. The circuit board 4 and the cover plate 2 have a plurality of through holes 16 arranged in a rectangular array. The housing 1 has a plurality of protrusions 17, which pass through the through holes 16 and are detachably connected to the locking member. Specifically, as shown... Figure 3 As shown, the recessed groove 15 opened at the opening of the groove 5 not only provides initial spatial positioning for the circuit board 4, facilitating assembly, but also restricts the movement of the circuit board 4 through its depth, thereby improving the installation stability of the circuit board 4. Furthermore, the insertion and engagement of several bosses 17 with through holes 16 can achieve multi-point installation limitation for the circuit board 4 and the cover plate 2. At the same time, the locking component can be a screw, which is readily available and easy to install and remove. Thus, the cover plate 2 can be firmly installed onto the housing 1 through the locking component, thereby firmly pressing the circuit board 4 into the recessed groove 15. The structural design is simple and reasonable.

[0042] In one embodiment, a first identifier 18 is provided on the side of the button panel 3 away from the housing 1 and corresponding to the positions of several buttons 7; a second identifier is provided on the housing 1 corresponding to the positions of the wiring terminals 6. Specifically, as shown... Figures 1 to 4 As shown, the first identifier 18 facilitates the user to press different positions of the button 3 to control the present invention, and reduces equipment failure or damage caused by user misoperation; at the same time, the second identifier can provide the user with guidance on the wiring sequence and steps, enabling the user to quickly complete the installation and debugging of the equipment, making it convenient to use.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
