Description

Technical Field

[0001] This invention belongs to the technical field of smart home, and specifically relates to a smart home switch device. Background Technology

[0002] With the deep integration of IoT technology and artificial intelligence, smart home switches have evolved from simple circuit controllers into distributed smart nodes with edge computing capabilities. Modern smart switches can not only receive remote commands from mobile apps, but also have built-in AI chips to support localized offline voice recognition, gesture control, and adaptive energy-saving algorithms based on user behavior habits. As the physical interaction interface of the whole-house smart system, it plays a key role in data collection and command execution, and is the core hardware for realizing the interconnection of home devices across all scenarios.

[0003] Currently available smart switch products equipped with artificial intelligence technology have a significant shortcoming in terms of subsequent maintenance and upgrades. Their installation structure mostly continues the traditional mechanical fixing method of "screws and clips," which is extremely cumbersome to disassemble. Users or maintenance personnel need to carefully pry open the clips with professional tools such as screwdrivers to remove the switch. A slight mistake can easily cause irreparable scratches to the pristine white wall surface with the sharp edges of the tools, or even directly touch the delicate internal AI microphone array and various high-sensitivity sensor modules, damaging these fragile components and affecting the normal operation of core AI functions such as voice wake-up and environmental perception. Furthermore, for the vast majority of ordinary household users, the lack of professional knowledge often prevents them from disassembling and assembling smart switches with their complex AI processing circuits and dense wiring. As a result, when software failures or hardware aging occur after long-term use, they can only seek help from professional technicians for on-site service. This not only significantly increases the after-sales service costs for manufacturers and the time costs for users, but also fails to respond in a timely manner to the users' growing demand for smart home hardware to be able to iterate as quickly as software and support self-maintenance and upgrades. Summary of the Invention

[0004] The purpose of this invention is to provide a smart home switch device that addresses the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A smart home switch device includes a disassembly component, comprising a junction box embedded in the wall, a smart switch panel inside the junction box, two bolts inside the smart switch panel, a metal frame on the front of the smart switch panel, a protective plate embedded inside the metal frame, and four corners of the front of the smart switch panel fixedly connected to inserts inserted into the metal frame, each insert having a positioning post inserted inside; the metal frame having a disassembly assembly that moves the positioning posts left and right; a push-out component including four top blocks slidably connected to the metal frame, each top block having a rectangular plate fixedly connected to its left and right sides, and a tension spring between the back of the rectangular plate and the metal frame; and an opening component including a movable plate slidably connected to the metal frame, the movable plate having a movable post fixedly connected to its front.

[0006] As a preferred embodiment of the smart home switch device of the present invention, the assembly includes a slider that is slidably connected to the inside of a metal frame, a control block that is fixedly connected to the top of the slider, a rack that is fixedly connected to the side of the slider away from the insert block, two gears that are rotatably connected inside the metal frame, a first magnetic block that is embedded inside the side of the control block away from the rack, and a second magnetic block that is fixedly connected to the inside of the metal frame.

[0007] In a preferred embodiment of the smart home switch device of the present invention, the second magnetic block is located on the side of the first magnetic block away from the control block, the second magnetic block and the first magnetic block are positioned corresponding to each other and are magnetically attracted to each other, and the positioning post is fixed to the slider.

[0008] As a preferred embodiment of the smart home switch device of the present invention, the top of the control block is provided with a protective groove, and the rack meshes with the gear.

[0009] As a preferred embodiment of the smart home switch device of the present invention, the slider has a groove inside, and fourteen rollers are rotatably connected inside the slider, and the rollers are arranged vertically.

[0010] As a preferred embodiment of the smart home switch device of the present invention, the fourteen rollers are evenly distributed along the inclined surface of the groove, the rollers abut against the top block, the corner of the top block near the groove is rounded, and the two ends of the tension spring are respectively fixed to the rectangular plate and the metal frame.

[0011] As a preferred embodiment of the smart home switch device of the present invention, four rotating shafts are rotatably connected inside the metal frame, a turntable is fixedly connected to one end of the rotating shaft near the plug, a coil spring is provided between the rotating shaft and the metal frame, and four push plates are slidably connected inside the metal frame, with a connecting rope fixedly connected to the side of the push plate near the turntable.

[0012] As a preferred embodiment of the smart home switch device of the present invention, a coil is fixedly connected to the outside of the rotating shaft, the end of the connecting rope away from the push plate is fixed to the coil, and the connecting rope is wound on the coil. The two ends of the coil spring are respectively fixed to the rotating shaft and the metal frame.

[0013] As a preferred embodiment of the smart home switch device of the present invention, four movable plates are arranged around the plug, the movable plates are in contact with the plug, the turntable and the movable column are provided with movable grooves at corresponding positions, and the movable column is movably connected inside the movable groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This device achieves tool-free maintenance through magnetic assembly and disassembly components. Users only need to squeeze the control block with one hand to overcome magnetic force to unlock. The gear and rack transmission principle synchronously drives the four positioning columns to retract, instantly releasing the locked state of the metal frame. Compared with the traditional prying disassembly method, it completely avoids the use of tools, solves the problem of difficult disassembly and assembly for ordinary users, effectively prevents panel scratches and wall base damage, and greatly improves the convenience of later maintenance.

[0015] 2. Through the designed ejector component, when the slider moves inward, the grooved inclined surface, in conjunction with the roller, pushes the top block to move, automatically pushing the metal frame away from the wall to create an operating gap. This mechanical linkage design requires no electric drive; it relies on the physical structure to achieve the panel's "self-pop-up," avoiding static electricity adsorption or dust accumulation that can cause jamming due to prolonged contact with the wall, ensuring that users can easily remove the panel.

[0016] 3. The designed opening mechanism effectively solves the lifespan problem caused by repeated friction between the insert and the frame. During disassembly, the slider triggers the turntable to rotate, which in turn drives the surrounding movable plates to open outward through the movable column, eliminating the clamping force on the insert and making the separation process smooth and unobstructed. After installation, it can automatically reset and clamp, greatly reducing hard wear between components and extending the service life of the plastic insert and the metal frame.

[0017] 4. The device achieves dual stability protection in its structure. On the one hand, the attraction between the first and second magnetic blocks firmly locks the slider when not in operation, preventing the frame from accidentally falling off due to accidental touch or vibration. On the other hand, the protective plate uses a visible touch screen material, which does not affect touch operation and provides physical protection. The overall structure ensures convenient disassembly and assembly while taking into account shock resistance and safety in daily use. Attached Figure Description

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0022] Reference Figure 1 - Figure 5This is the first embodiment of the present invention. This embodiment provides a smart home switch device, which achieves the effect of convenient disassembly and maintenance of the switch. It includes disassembly and assembly components, including a junction box 10 embedded in the wall. The junction box 10 has a smart switch panel 11 inside. The smart switch panel 11 has two bolts 12 inside. The front of the smart switch panel 11 has a metal frame 13. The metal frame 13 has a protective plate 14 embedded inside. Each of the four corners of the front of the smart switch panel 11 has a plug 15 that is inserted into the metal frame 13. The plug 15 has a positioning post 16 inserted inside. The metal frame 13 has a disassembly and assembly component 17 that drives the positioning post 16 to move left and right.

[0023] Specifically, the smart switch panel 11 is installed with two bolts 12. The metal frame 13 is abutted against the front of the smart switch panel 11 by four inserts 15. The four positioning posts 16 are inserted into the inside of the inserts 15 under the action of four sliders 171. At this time, the first magnetic block 175 and the second magnetic block 176 inside the control block 172 attract each other, so that the positioning posts 16 are firmly inserted into the inside of the inserts 15, and the metal frame 13 and the smart switch panel 11 are assembled. The protective plate 14 is made of a visible touch screen material, so that the protective plate 14 can protect the control panel of the smart switch panel 11 while operating it.

[0024] Furthermore, the assembly 17 includes a slider 171 that slides left and right inside the metal frame 13. A control block 172 is fixedly connected to the top of the slider 171. A rack 173 is fixedly connected to the side of the slider 171 away from the insert block 15. Two gears 174 are rotatably connected inside the metal frame 13. A first magnetic block 175 is fitted inside the side of the control block 172 away from the rack 173. A second magnetic block 176 is fixedly connected inside the metal frame 13.

[0025] The four racks 173 mesh with the two gears 174 respectively, forming a linkage transmission mechanism. When it is necessary to disassemble the metal frame 13 and its attached protective plate 14, the user only needs to press one pair of control blocks 172 to drive the connected slider 171 to produce lateral displacement. This action will synchronously drive another pair of sliders 171 through the meshing mechanism, so that it moves smoothly away from the insert block 15. During this process, the four positioning pins 16 will synchronously and smoothly exit from the inside of the four insert blocks 15, thereby releasing the fixed constraint on the metal frame 13 and the protective plate 14, so as to quickly remove the metal frame 13 and the protective plate 14 and efficiently complete the entire disassembly operation.

[0026] Preferably, the second magnetic block 176 is located on the side of the first magnetic block 175 away from the control block 172. The second magnetic block 176 and the first magnetic block 175 are positioned corresponding to each other and are magnetically attracted to each other. The positioning post 16 is fixed to the slider 171. A protective groove is provided on the top of the control block 172. The rack 173 meshes with the gear 174.

[0027] It should be noted that the design of the second magnetic block 176 and the first magnetic block 175 allows the slider 171 to move the control block 172 to a position where the first magnetic block 175 and the second magnetic block 176 are in contact. This magnetic attraction helps to fix the position of the slider 171, ensuring that the positioning post 16 remains stably inserted into the plug 15. This eliminates the need for the user to continuously press the control block 172, making the structure of the smart home switch device more stable and preventing the metal frame 13 from accidentally coming loose, thus greatly improving the reliability of the device.

[0028] In initial use, the metal frame 13 abuts against the front of the smart switch panel 11, and the positioning post 16 is inserted into the insert block 15 under the action of the slider 171, control block 172, first magnetic block 175, and second magnetic block 176, ensuring a stable assembly of the metal frame 13 and the smart switch panel 11. When the device malfunctions and the smart switch panel 11 needs to be removed for repair or the damaged metal frame 13 needs to be replaced, pinch the two corresponding control blocks 172 (e.g., two on the right or two on the left) simultaneously with the middle finger and thumb of the right hand, and move the right hand inward, thereby simultaneously pushing the two control blocks 172 inward. At this time, the pushing force is greater than the attraction force of the first magnetic block 175 and the second magnetic block 176, causing the control block 172 to overcome the attraction force and drive the slider 171 to move. This causes the control block 172 to drive the slider 171 to move inward, and the slider 171 drives the positioning post 16 to disengage from the insert block 15. At this time, the metal frame 13 can be directly removed from the insert block 15. When the frame 13 and protective plate 14 are removed, and the control block 172 is moved, the slider 171 drives the rack 173 to move synchronously. The rack 173 drives the gear 174 to rotate through meshing, so that the two sliders 171 can move synchronously. This allows the movement of the other two sliders 171 by moving the two sliders 171 on one side, ensuring that the four positioning posts 16 are simultaneously dislodged from the four inserts 15. The disassembly and assembly process does not require additional tools and is very simple to operate. This avoids the problem of existing smart switches where the metal frame 13 needs to be disassembled by using a pry bar or flathead screwdriver inserted into the gap between the wall and the metal frame 13. This can easily cause scratches on the metal frame 13 and the switch panel surface. It can also damage the wall base due to improper control of the prying force, affecting the aesthetics of the switch installation area. At the same time, ordinary disassembly and assembly operations require the use of special tools, which makes it difficult for ordinary users to disassemble and repair themselves, and cannot meet the needs of quick disassembly and assembly. Example

[0029] Reference Figure 1 - Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a top-out component for a smart home switch device, which solves the problem that the metal frame 13 is too close to the wall and is inconvenient for users to pry it out. It includes four top blocks 21 that are slidably connected to the inside of the metal frame 13. Rectangular plates 22 are fixedly connected to the left and right sides of each top block 21. A tension spring 23 is provided between the back of the rectangular plate 22 and the metal frame 13. A groove 20 is provided inside the slider 171. Fourteen rollers 24 are rotatably connected inside the slider 171 and are arranged vertically.

[0030] Specifically, the top block 21 pushes the metal frame 13 out of the smart switch panel 11 by a certain distance, creating a gap between the metal frame 13 and the wall that can be pried out with a finger. Users can then easily remove the metal frame 13 and the protective plate 14 as a whole, further reducing the difficulty of disassembly and preventing the disassembly and assembly efficiency from being affected by the metal frame 13 being stuck to the wall for a long time and the gap being too small to pry it out.

[0031] Furthermore, fourteen rollers 24 are evenly distributed along the inclined surface of the groove 20. The rollers 24 abut against the top block 21. One corner of the top block 21 near the groove 20 is rounded. The two ends of the tension spring 23 are fixed to the rectangular plate 22 and the metal frame 13, respectively.

[0032] Preferably, the top block 21 has a rounded corner near the groove 20, which allows the top block 21 to move smoothly along the inclined surface of the groove 20. When the slider 171 resets and moves outward, the top block 21 is reset and retracted into the metal frame 13 under the pulling force of the tension spring 23, which will not affect the normal assembly of the metal frame 13 and the smart switch panel 11.

[0033] In use, initially, the top block 21, under the elastic restoring force of the tension spring 23, maintains an inwardly retracted posture, completely retracted into the internal space of the metal frame 13. In this state, the end of the top block 21 near the smart switch panel 11 is in close contact with the surface of the smart switch panel 11, forming a gapless fit, thereby ensuring a stable fit between the metal frame 13 and the front of the smart switch panel 11. When the operating slider 171 moves inward, causing the positioning post 16 on it to disengage from the slot of the insert block 15, the slider 171 can continue its inward stroke. As the slider 171 continues to advance inward, the groove 20 located inside the slider 171 also moves inward synchronously. The inclined surface design of the groove 20 gradually approaches the top block 21 during this process. In the initial stage of movement, the groove 20 first contacts the rounded corner structure at the front end of the top block 21. As the slider 171 drives the groove 20 to move further inward, the inclined surface of the groove 20 begins to apply an outward pushing force to the top block 21. Under this thrust, the top block 21 begins to overcome the inward pulling force exerted on it by the tension spring 23 and gradually moves towards the smart switch panel 11. As the top block 21 continues to move forward, it pushes the metal frame 13 to move away from the front of the smart switch panel 11, thereby creating a clear operating gap between the metal frame 13 and the smart switch panel 11. At this time, the user does not need to use any tools to pry it out by inserting them into the gap; they can simply pinch the edge of the pushed-out metal frame 13 with their fingers and easily remove it from the smart switch panel 11. Throughout the movement of the slider 171, the top block 21 and the auxiliary rolling roller 24 maintain rolling contact. This rolling friction mechanism significantly reduces the sliding friction force experienced by the slider 171 during movement, effectively avoiding the movement jamming or obstruction that may occur due to excessive friction, and ensuring a smooth and seamless disassembly process. Example

[0034] Reference Figure 1 - Figure 9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an opening component for a smart home switch device, which solves the problem of easy wear and tear during the reciprocating insertion and connection of the plug 15 and the metal frame 13 during installation. It includes a movable plate 30 slidably connected inside the metal frame 13. A movable column 31 is fixedly connected to the front of the movable plate 30. Four rotating shafts 32 are rotatably connected inside the metal frame 13. A turntable 33 is fixedly connected to one end of the rotating shaft 32 near the plug 15. A coil spring 34 is provided between the rotating shaft 32 and the metal frame 13. Four push plates 35 are slidably connected laterally inside the metal frame 13. A connecting rope 36 is fixedly connected to the side of the push plate 35 near the turntable 33.

[0035] Specifically, the curved movable groove allows the rotation of the turntable 33 to drive the four push plates 35 to move synchronously toward the insertion block 15. When installing or removing the metal frame 13, the four movable plates 30 are far away from the insertion block 15, which will not cause wear, reduce wear between components, and extend the overall service life of the device. When the device is in daily use, the four movable plates 30 are clamped around the insertion block 15 under the action of the coil spring 34, maintaining the connection stability between the metal frame 13 and the insertion block 15.

[0036] Furthermore, a coil is fixedly connected to the outside of the rotating shaft 32, and the end of the connecting rope 36 away from the push plate 35 is fixed to the coil. The connecting rope 36 is wound around the coil. The two ends of the coil spring 34 are fixed to the rotating shaft 32 and the metal frame 13 respectively. Four movable plates 30 are arranged around the insert block 15. The movable plates 30 are in contact with the insert block 15. Movable grooves are opened at the corresponding positions of the turntable 33 and the movable column 31, and the movable column 31 is movably connected inside the movable groove.

[0037] In use, the coil spring 34 is initially in a wound state, and the rotating shaft 32 is in its initial position under the action of the coil spring 34. At this time, the movable column 31 is located at the end of the movable groove of the turntable 33 near the center. The movable plate 30 abuts against the periphery of the insert block 15. As the slider 171 continues to move inward, the slider 171 contacts the push plate 35 and drives the push plate 35 to move inward synchronously, causing the push plate 35 to pull the connecting rope 36. The connecting rope 36 drives the coil to rotate, and the coil drives the rotating shaft 32 to rotate clockwise. At the same time, the rotating shaft 32 drives the turntable 33 to rotate, and the coil spring 34 unfolds. During the rotation of the turntable 33, the movable column 31 moves inside the movable groove. The groove wall pushes the movable column 31 to move away from the center, so that the movable column 31 drives the movable plate 30 to open away from the insert block 15. This makes it smoother when the metal frame 13 is pulled away from the wall and the insert block 15 is disengaged from the metal frame 13, avoiding adhesion and jamming that could cause the metal frame to... The inability to remove the insert 13 smoothly further improves the smoothness of disassembly and assembly, while avoiding excessive wear between the insert 15 and the metal frame 13 due to repeated insertion and removal over a long period of time, thus extending the service life of the insert 15 and the metal frame 13. When the metal frame 13 needs to be reinstalled, since the four movable plates 30 are still in the open state, the gap between the four inserts 15 is greater than the size of the insert 15, which allows the four inserts 15 to be quickly aligned and inserted into the corresponding slots of the metal frame 13 during insertion. After being inserted into place, the control block 172 is pushed in the opposite direction to drive the slider 171 to reset. The push plate 35 is no longer pushed by the slider 171, and the rotating shaft 32 is reset under the action of the spring force of the coil spring 34. The rotating shaft 32 drives the turntable 33 to rotate in the opposite direction, so that the movable column 31 drives the movable plate 30 to reset and clamp the insert 15 again, completing the positioning and installation of the metal frame 13, further reducing the difficulty of installation alignment and improving the overall efficiency of disassembly and assembly operations.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
