Description

Technical Field

[0001] This invention relates to switch panels, and more particularly to a mounting structure for a button panel on a switch panel for push-to-control operation. Background Technology

[0002] Switch panels are indispensable core components in circuit systems, primarily used for controlling the on / off state of circuits, and are widely used in various scenarios such as residential, office, and commercial buildings. The core working structure of a switch panel mainly consists of a panel frame, a button panel, a resilient reset component, a circuit board, and a tactile switch. The button panel, the user's direct interactive component, is movably mounted on the panel frame. By pressing the button panel, the user triggers the tactile switch on the circuit board, thereby controlling the circuit's on / off state. To ensure stable reciprocating movement of the button panel without it detaching, existing technologies generally incorporate a resilient reset component between the button panel and the panel frame, using matching hooks and slots for limiting the assembly. The gap between the latch and the slot limits the travel of the keypad, ensuring the accuracy of the quick-release button's press stroke. When the user presses the keypad, it compresses the elastic reset element and moves inward to touch the tactile switch, completing the circuit switching operation. When the pressure is released, the elastic reset element's rebound force drives the keypad to spring outward, resetting it and disengaging it from the tactile switch until the latch is blocked by the slot, thus completing a full switching action. This structure effectively ensures that the keypad does not loosen or shift during long-term repeated use, and the quick-release button operation is stable and smooth, therefore it is widely used in existing switch panel products.

[0003] However, the existing button panel assembly method using a hook and slot limiting structure has significant technical defects in actual inspection, maintenance, and replacement operations, making it difficult to meet the current needs of convenient operation and maintenance, cost reduction, and efficiency improvement in use and production. Whether it is a circuit fault, routine maintenance, or a problem with the switch panel itself, workers must first remove the button panel before they can remove the bolts used to fix the panel frame, which are obscured by the button panel. However, the existing hook and slot are rigid snap-fit ​​structures, with a narrow disassembly space between them and no convenient force application points, making the button panel extremely difficult to disassemble and requiring a high level of professional expertise. At the same time, the hook is integrated into the button panel, and its base is a slender structure. During the disassembly process, maintenance and installation personnel are very likely to cause the hook to break brittlely due to improper force application, incorrect force angle, or deviation of the prying point. In civil and conventional engineering use scenarios, spare parts for the button panel are almost never provided separately. Once the button panel hook is broken or damaged, it is impossible to replace and repair the quick-release button structure alone; the entire switch panel must be replaced.

[0004] The aforementioned problems not only significantly increase the operation and maintenance costs and replacement costs of switch panels, resulting in a large waste of electrical component resources and reducing the overall lifespan of switch panels, but also increase the workload of after-sales maintenance of building electrical systems, affecting users' normal power usage experience. Furthermore, the traditional snap-fit ​​assembly and disassembly structure is cumbersome and inefficient, hindering the large-scale production and assembly of switch panels and subsequent rapid maintenance operations. Summary of the Invention

[0005] The purpose of this invention is to provide a switch panel that allows for easy installation and removal of the button board, thereby reducing the difficulty of installation, removal, and maintenance of the switch panel and the risk of damage, and improving the efficiency of installation and removal and the service life of the product.

[0006] The button plate mounting structure of the switch panel of the present invention includes a fixedly mounted middle frame and a button plate mounted on the outside of the middle frame, a quick-release device and a spring arm that applies an outward force to the button plate, and a limiting groove parallel to the wall surface on the middle frame. A button hole is provided on the side of the middle frame, and the direction of the button hole is parallel to the limiting groove. The quick-release device includes a limiting hook that engages with the limiting groove and can move along the limiting groove, a quick-release key extending to the button hole, and a positioning groove perpendicular to the wall surface with its opening pointing towards the button hole. One side of the button plate is movably connected to the middle frame, and a positioning hook that moves within the positioning groove is provided on the button plate opposite to the positioning groove. A resilient reset member is also installed between the middle frame and the quick-release device, and the reset member applies a spring force to the quick-release device pointing towards the outer end of the button hole. The quick-release device moves inward along the button hole and can disengage the positioning groove from the positioning hook.

[0007] The switch panel mounting structure of this invention features a switch base box that is mounted on a wall via pre-embedding or surface mounting, while the switch panel's middle frame is bolted to the base box. The circuit board can be mounted on the inner side of the middle frame's backrest or directly on the middle frame, forming a thinner switch panel. A tactile switch can be installed on the circuit board, and a corresponding actuation post is provided on the button panel. When the user presses the button panel, the actuation post activates the tactile switch, controlling the circuit's connection or disconnection, and the electrical appliance starts or stops accordingly. Under normal conditions, the button panel is movably mounted on the middle frame via a connecting structure that allows for a movable connection between its side and the middle frame, as well as a connection between the positioning hook in the middle and the positioning groove on the quick-release mechanism. The button panel's interior is spring-loaded outward by a spring arm, causing the actuation post on the button panel to move away from the tactile switch on the circuit board. Simultaneously, a reset component applies a spring force pointing outward from the button hole, keeping the positioning groove in a position blocking the positioning hook. When the user presses the button panel, the locating hook moves inward along the locating groove, and the side of the button panel moves relative to the middle frame, causing the pressing post to actuate the tactile switch. To remove the button panel, press the quick-release button on the quick-release device inward, disengaging the locating groove from the locating hook. The button panel then loses its locating groove constraint and springs outward under the action of the spring arm, allowing the user or maintenance personnel to easily remove it. When manufacturing or replacing the button panel, align the button panel and press it inward to engage the locating hook with the locating groove on the quick-release device. This type of switch panel features a button plate mounting structure that allows for quick and easy removal of the button plate simply by pressing the quick-release button. Its low operational difficulty effectively improves assembly and disassembly efficiency and reduces maintenance costs. Furthermore, during disassembly, the movement of the positioning groove releases the obstruction of the limit hook, preventing structural damage to the hook and significantly reducing the risk of damage and resource waste. This meets industry demands for efficient, non-destructive assembly and disassembly, convenient maintenance, and low-loss use. Additionally, users can select and replace button plates of different colors and appearances according to personal preferences, decoration styles, and scene requirements, thus satisfying the personalized needs of different groups.

[0008] Preferably, the button panel includes several button plates arranged side by side, all button plates are connected and fixed to each other on the same side, and the side is movably connected to the middle frame. There is a gap between adjacent button plates, and each button plate has a positioning hook on its inner side. A spring arm is provided between the middle frame and each button plate.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0026] This invention proposes a button mounting structure for a switch panel.

[0027] The button plate mounting structure of the switch panel in this embodiment includes a fixedly mounted middle frame 1 and a button plate 2 mounted on the outside of the middle frame. It also includes a quick-release mechanism 3 mounted between the middle frame and the button plate, and a spring arm 4 that applies an outward force to the button plate. The middle frame has a limiting groove 11 parallel to the wall surface, and a button hole 12 on the side of the middle frame, with the direction of the button hole parallel to the limiting groove. The quick-release mechanism has a limiting hook 31 that engages with the limiting groove and can move along the limiting groove, a quick-release button 32 extending to the button hole, and a positioning groove 33 perpendicular to the wall surface with its opening pointing towards the button hole. One side of the button plate is movably connected to the middle frame, and a positioning hook 21 that moves within the positioning groove is located on the button plate opposite to it. A resilient reset member 5 is also installed between the middle frame and the quick-release mechanism, applying a spring force to the quick-release mechanism pointing towards the outside of the button hole. The quick-release mechanism moves inward along the button hole and can disengage the positioning groove from the positioning hook.

[0028] like Figure 1-4As shown, a rear seat 6 is installed on the inner side of the middle frame 1, and a circuit board 7 is installed on the rear seat, with several tactile switches 8 mounted on the circuit board. Actuation holes 13 are opened on the middle frame opposite to the tactile switches, and a pressing post 22 for pressing the tactile switches is provided on the button panel 2 opposite to the actuation holes. Furthermore, the limiting groove 11 on the middle frame 1 is vertically arranged, and the button hole 12 is located at the bottom of the middle frame 1. The vertical dimension of the limiting hook 31 is smaller than the limiting groove, allowing it to move up and down along the limiting groove. Simultaneously, the quick-release button 32 is vertically movable and positioned at the button hole, allowing the quick-release button to be better hidden at the bottom of the switch panel, which is not easily visible. Under normal conditions, the keypad is movably mounted on the middle frame via a relatively movable connection between its top side and the middle frame, and the connection between the positioning hook in the middle and the positioning groove on the quick-release mechanism. The keypad's interior is pushed outward by a spring arm, causing the push button on the keypad to disengage from the tactile switch on the circuit board. Simultaneously, a reset component applies a downward-pointing spring force to the quick-release mechanism, keeping the upward-bent end of the positioning hook within the positioning groove, thus maintaining the positioning groove in a position that blocks the positioning hook. When the user presses the keypad, the positioning hook moves inward along the positioning groove, the top side of the keypad moves relative to the middle frame, and the positioning hook moves inward along the positioning groove until the push button on the keypad actuates the tactile switch, thereby controlling the connection or disconnection of the circuit, and the electrical appliance starts or stops accordingly. When the keypad needs to be disassembled, press the quick-release button on the quick-release device from the bottom. The quick-release button moves upward and moves the limit hook along the limit groove, causing the downward-facing opening of the positioning groove to disengage from the positioning hook. The keypad then loses the restriction of the positioning groove and will spring open outward under the action of the spring arm. At this time, the user or maintenance personnel can easily remove the keypad. When the user stops pressing the quick-release button, the quick-release device resets under the action of the reset component, so that the positioning groove returns to the position opposite to the positioning hook. After the circuit repair or parts replacement is completed, align the keypad and press it inward to make the positioning hook engage with the positioning groove on the quick-release device.

[0029] The button panel mounting structure of the switch panel allows the side of the button panel to be movably connected to the middle frame via a hinge. After the positioning hook on the button panel disengages from the quick-release mechanism, the button panel rotates outward under the action of the spring arm, allowing the user to easily remove the hinged end. Alternatively, the button panel and the middle frame can be connected via a locking structure with a certain amount of clearance between them. When the positioning hook on the button panel disengages from the quick-release mechanism, the locking structures will also misalign to a certain extent, allowing for easier removal of the button panel. The button panel and the middle frame can also be connected as follows: Figure 2-4As shown, on the middle frame 1, specifically opposite the top edge of the button plate 2, there is a protruding horizontal bar 14. On the side of the middle frame facing the limiting groove 11, i.e. below the horizontal bar, there are several guide grooves 15 parallel to the limiting groove. The horizontal bar also has a positioning hole 16 connecting the guide groove and the other side of the horizontal bar, i.e., the positioning hole passes through the upper and lower sides of the horizontal bar and connects to the top of the guide groove. A cylindrical positioning rod 17 connecting the two side walls is provided in the middle of the guide groove. On the button plate 2, opposite to the guide groove, there is a positioning plate 23. At the end of the positioning plate, i.e. the top of the positioning plate, there is a positioning block 24 extending into the positioning hole. The positioning plate also has an arc-shaped positioning groove 25 opposite to the positioning rod. Under normal conditions, the positioning plate on the top side of the button panel is located in the guide groove of the middle frame, with the positioning groove opposite the positioning rod and the positioning block inserted into the positioning hole of the horizontal bar. When the user presses the button panel, the positioning hook moves inward along the positioning groove, causing the positioning groove to press on the positioning rod and rotate relative to the positioning rod until the pressing post presses the tactile switch. When the button panel is disassembled and the positioning hook is disengaged from the positioning groove, the spring arm applies an outward force to the button panel, causing the positioning groove to move away from the positioning rod, and the positioning block on the positioning plate will also disengage from the positioning hole on the horizontal bar. This allows the top of the button panel to be directly separated from the middle frame. At this point, the operator can remove the button panel directly without any further operations, greatly improving the convenience of disassembly. The guide groove 15 extends through both sides of the middle frame 1, and the positioning hole 16 also connects to the back side of the middle frame. When removing the button plate, the positioning block on the positioning plate can rotate more smoothly along the positioning hole and guide groove, so that the button plate is separated from the middle frame. At the same time, the quick release device moves up and down. Due to the influence of gravity, the requirement for spring force can be reduced. The reduction of spring force will not affect the operation of the quick release device.

[0030] like Figure 3As shown, the middle frame 1 is provided with a limiting post 18, and the touch hole 13 is provided on the limiting post. The two ends of the touch hole are respectively opposite to the tactile switch and the pressing post, so that the pressing post can be inserted into the touch hole to press the tactile switch. At the same time, the quick release device 3 is provided with a limiting elongated hole 34 that fits outside the limiting post. When the operator presses the quick release button, the limiting elongated hole of the quick release device moves relative to the limiting post until the bottom of the limiting elongated hole abuts against the limiting post. At this time, the positioning groove also disengages from the positioning hook on the button plate. When the operator stops pressing the quick release button, the quick release device moves downward under the action of the reset component until the top of the limiting elongated hole abuts against the limiting post. At this time, the quick release button is parallel to the bottom edge of the middle frame, thus ensuring aesthetics. In addition, the quick-release device 3 can be connected to the quick-release key 32 via two limiting rods 35 parallel to the limiting groove 11. The middle frame 1 is provided with a limiting block 19 located between the two limiting rods. This limiting block can also be opposite to the quick-release device when it moves up and down, thereby improving guidance and limiting. The reset member 5 is a spring disposed between the two limiting rods 35. The two ends of the spring abut against the limiting block 19 and the quick-release key 32 respectively, thereby providing a stable restoring force for the quick-release device. The spring arm 4 is mounted on the quick release device 3, and the spring arm is inclined from the side away from the button hole 12 to the side closer to the button hole, that is, from top to bottom and outward. Under normal conditions, the spring arm applies an outward elastic force to the button plate, and the gap between the button plate and the quick release device gradually increases from top to bottom. When the quick release device moves upward, the spring arm also moves upward, and the gap at the position of the spring arm becomes smaller and smaller. The spring arm gradually contracts under pressure, and its elastic deformation gradually increases until the positioning groove and positioning hook disengage. The spring arm can then push the button plate outward with greater elastic force, so that the top edge of the button plate can be more easily separated from the middle frame.

[0031] Currently, most switch panels on the market are equipped with 1 to 4 independent control buttons, corresponding to the same number of independent button panels, depending on the functional requirements. Users can choose the switch panel with the appropriate button specifications based on the number of electrical devices in the scenario, daily operating habits, and the overall aesthetic requirements of home and commercial decoration, making it quite flexible in adapting to different scenarios. However, in existing technologies, each button panel of each specification of switch panel is an independent, separate structure. During assembly and disassembly, workers need to align, snap, fix, or disassemble each button panel one by one. The button assembly and disassembly steps for a single switch panel are numerous and the operation process is cumbersome, greatly increasing the labor cost of production assembly and reducing product assembly efficiency. In addition, during the later use of the switch panel, if a single button panel malfunctions such as jamming, damage, or failure, it is necessary to disassemble the surrounding structure one by one to complete the removal and replacement of the faulty button panel, making the repair operation difficult and time-consuming. Therefore, the button panel installation structure of the switch panel described in this invention can be as follows: Figure 5 As shown, it illustrates a switch panel with 1 to 3 control buttons. In this case, the button panel 2 comprises several button plates 26 arranged side by side, with all button plates on the same side, i.e., Figure 2 , 3 The top side shown is connected and fixed to each other, and this side is movably connected to the middle frame 1. There is a gap 27 between adjacent buttons. The inner side of each button is provided with a positioning hook 21 and a pressing post 22. The gap setting allows each button to form a relatively independent control button. Pressing any button will not provide enough force to press the tactile switch of the adjacent button. The user can control the corresponding circuit through each button without causing misoperation. At the same time, there is a spring arm 4 between the middle frame and each button. The quick release 3 is provided with a positioning groove 33 relative to each button. When the user presses the quick release button, it can drive the quick release 3 to disengage from all buttons, thereby realizing the operation of disassembling all buttons with one click, which greatly improves the disassembly convenience of the multi-button switch panel. To further prevent pressing one button from causing another button to press the tactile switch, an inwardly recessed partition groove 28 can be provided on the connecting end of all buttons 26 opposite to the gap 27. This partition groove does not connect the front and back sides of the button panel like the gap, but is only slightly recessed to reduce the structural strength at this position. Combined with the gap, this allows each button to be pressed more independently. The cascading force it generates on adjacent buttons is less than the elastic force of the spring arm, so that adjacent buttons will not move inward and thus will not cause misoperation.

[0032] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
