Description

Technical Field

[0001] This utility model relates to the field of touch switch technology, and in particular to a smart touch switch fixing component. Background Technology

[0002] Touch switches, as an important component of smart homes and modern building electrical control, are gradually replacing traditional mechanical push-button switches due to their advantages such as convenient operation, stylish appearance, and ease of integration with intelligent control functions. These switches typically include a faceplate for user interaction, a frame structure (such as a middle frame) that supports and protects internal electronic components, and a base that houses the core circuitry, wiring terminals, and provides mounting points.

[0003] In existing technologies, the faceplate and frame structure are mostly fixed using snap-fit ​​or direct ultrasonic welding. While ultrasonic welding provides a strong connection, its non-removable nature causes great inconvenience for subsequent maintenance, replacement of internal components, or upgrades to functional modules. Once welding is completed, repairing internal circuit boards or relays often requires destructive disassembly, leading to component damage, increased maintenance costs, and wasted resources.

[0004] On the other hand, the connection between the frame structure (middle frame) and the base also presents significant problems. Common solutions include: Pre-assembly positioning difficulties: During assembly, if multiple snap-fit ​​points are not aligned precisely or have slight tolerances, it may result in uneven or skewed installation, or require greater force to snap together, increasing assembly difficulty and even causing damage to components.

[0005] Prolonged use can lead to aging and failure: Plastic clips, after prolonged stress or temperature changes, are prone to creep or aging and brittleness, resulting in decreased locking force or even breakage and insecure installation. Therefore, a smart touch switch fixing component is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0007] Therefore, one objective of this utility model is to provide a smart touch switch fixing component to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0008] To achieve the above objectives, one embodiment of the present invention provides a smart touch switch fixing assembly, including a face cover, a middle frame, fasteners, and a base. The bottom of the face cover is fixedly connected to the middle frame, and fasteners are fixedly connected to the four corners of the middle frame. The fasteners are bent. The bottom of the middle frame is detachably connected to a base, and a protrusion is fixedly connected to the side of the base. The fastener is pressed against the side and bottom of the protrusion. The protrusion is hollow inside, and a fastener is movably connected inside the protrusion. The thickness of the fastener gradually increases from bottom to top. The raised surface is provided with a guide groove, and a movable column is movably connected to the inner side of the guide groove. The movable column is fixedly connected to the surface of the fastener. The fastener is screwed down and secured to the surface of the fastener, and several mounting feet are fixedly connected to both sides of the base.

[0009] Preferably, of any of the above solutions, the material of the face cover is ABS, and the middle frame is ultrasonically welded to the face cover.

[0010] The above technical solution employs a faceplate, which is the part that the user directly contacts. It is insulated, wear-resistant, and translucent. The surface can be printed / engraved with icons and text (such as "on" and "off"), or a semi-transparent material can be used in conjunction with LED indicator lights to display the status (such as red for off and green for on).

[0011] The middle frame supports the front cover and internal circuit board, preventing deformation. The middle frame is detachably connected to the base. The base houses the core components and wiring, accommodating circuit boards, relays, power modules, etc., with reserved wiring space. It is made of flame-retardant material and has internal isolation grooves to prevent electric shock or short circuits. The base is installed in the switch box via mounting feet.

[0012] Preferably, of any of the above solutions, the fastener is L-shaped, and the middle frame and the fastener are made of metal.

[0013] The above technical solution is adopted because the fixing component is easy to assemble, uses fasteners for assembly, and can be easily disassembled while being firmly and securely assembled, thus abandoning the use of welding. When assembling the middle frame and the base, the middle frame is fastened to the top surface of the base, and then force is applied to the fastener to bend and press it against the predetermined protrusion on the side of the base. The fastener is pressed against the side and bottom of the protrusion. The protrusion is hollow, and a movable column is used to turn out the fan-shaped fastener inside the protrusion. The back of the fastener is movably connected to the front of the fastener, locking the fastener onto the protrusion, thereby achieving a firm and detachable assembly of the middle frame and the base.

[0014] Preferably, the fastener is made of plastic and has a fan-shaped shape.

[0015] The above technical solution comprises the following components: The cover serves as the user interface, made of ABS material to ensure insulation, wear resistance, and light transmittance. The surface features printed / engraved functional markings (such as "on" / "off"), or a semi-transparent area combined with internal LED status indicators (red light indicates off, green light indicates on).

[0016] Mid-frame: Metal stamping structure, with the top surface fixed to the cover via ultrasonic welding to form a rigid support frame to prevent deformation. The four corners extend downwards to form mounting points.

[0017] Fasteners: L-shaped metal components, fixed to the four corner bends of the middle frame. The vertical section is riveted to the middle frame, and the horizontal section extends inward to form a locking platform.

[0018] Base: Injection molded from flame-retardant engineering plastic, with an internal circuit board compartment, relay position, and isolated wiring groove (effectively preventing electric shock and short circuit). Bent mounting feet with mounting holes are provided on both sides for accommodating 86-type switch boxes.

[0019] Protrusions: Hollow columnar structures located at the four corners of the base, with an open top and spiral guide grooves on the inner sidewalls.

[0020] Fasteners: Fan-shaped plastic parts, with thickness increasing from bottom to top (wedge design), and the movable column is fixed by adhesive on the back.

[0021] Movable column: A cylinder embedded in a raised guide groove to control the lifting trajectory of the fastener.

[0022] Preferably, in any of the above embodiments, the fastener is bonded to the movable column, and the fastener can be completely retracted into the space inside the protrusion.

[0023] Core design: The front cover and the middle frame are permanently fixed together (ultrasonic welding). The middle frame and the base are detachably connected by fasteners, protrusions, and other fasteners. Initial positioning: The middle frame is fastened to the top surface of the base, and the fasteners are pressed against the outer and bottom surfaces of the protrusion; Secondary locking: Rotating the fastener drives the movable column to move along the guide groove, causing the fastener to unscrew from inside the protrusion. Its thickened end presses against the inner surface of the fastener, forming a wedge self-locking effect.

[0024] Preferably, in any of the above embodiments, the mounting foot is multi-segmented and the end of the mounting foot has a hole.

[0025] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This intelligent touch switch fixing component is easy to assemble using fasteners, allowing for easy disassembly while ensuring a secure and tight fit. It avoids the use of welding. When assembling the middle frame and base, the middle frame is fastened to the top surface of the base. Force is then applied to the fasteners, causing them to bend and press against a predetermined protrusion on the side of the base. Specifically, the fasteners press against the sides and bottom of the hollow protrusion. A movable column is used to rotate out the fan-shaped fasteners inside the protrusion. The back of the fasteners connects movably with the front of the fasteners, locking the fasteners onto the protrusion. This achieves a secure yet detachable assembly of the middle frame and base.

The thickness of the fastener 6 gradually increases from bottom to top. The surface of the protrusion 5 is provided with a guide groove 7, and a movable column 8 is movably connected to the inner side of the guide groove 7. The movable column 8 is fixedly connected to the surface of the fastener 6. Fastener 6 is screwed down and secured to the surface of fastener 3, and several mounting feet 9 are fixedly connected to both sides of the base 4.

[0032] Example 1: The faceplate 1 is made of ABS, and the middle frame 2 is ultrasonically welded to the faceplate 1. The fastener 3 is L-shaped, and the middle frame 2 and fastener 3 are made of metal. The fastener 6 is made of plastic and is fan-shaped.

[0033] Example 2: Faceplate 1 is the part that the user directly contacts. It is insulating, wear-resistant, and light-transmitting. The surface can be printed / engraved with icons and text (such as "on" and "off"), or use a semi-transparent material with LED indicator lights to show the status (such as red for off and green for on).

[0036] Middle frame 2: Metal stamping structure, the top surface is fixed to the cover 1 by ultrasonic welding to form a rigid support frame to prevent deformation. The four corners extend downward to form mounting points.

[0037] Fastener 3: An L-shaped metal component, fixed to the four corner bends of the middle frame 2. Its vertical section is riveted to the middle frame 2, and its horizontal section extends inward to form a locking platform.

[0038] Base 4: Injection molded from flame-retardant engineering plastic, with an internal circuit board compartment, relay position, and isolated wiring groove (effectively preventing electric shock and short circuit).

Its working principle is as follows: The faceplate 1 has a built-in touch sensor that senses user operations through different technologies: Capacitive touch: The sensor surface is covered with a conductive layer (such as an ITO film), forming an array of self-capacitance or mutual capacitance. When a finger (conductor) approaches, it changes the local capacitance value. The sensor detects the location and magnitude of the capacitance change and recognizes actions such as "tap, swipe, long press". Features: High sensitivity, supports multi-touch, suitable for fine-tuning operations (such as dimming swipes).

[0043] The working principle of this utility model is as follows: The assembly process is carried out in the following steps: Pre-assembly: Weld the faceplate 1 and the middle frame 2 into an integral component; Fastening and positioning: Press the middle frame 2 component vertically down to the base 4, so that the fastener 3 hooks the bottom edge of the protrusion 5; Mechanical locking: Use a special tool or your fingers to rotate the four corner fasteners 6; the movable column 8 moves downward along the spiral guide groove 7, pushing the fastener 6 outward to rotate out of the protrusion 5 cavity; as the rotation angle increases, the thickened area at the top of the fastener 6 continues to press against the inner wall of the fastener 3; when the maximum thickness section of the fastener 6 contacts the fastener 3, geometric self-locking is generated, applying a vertically downward locking force and a horizontally inward constraint force.

[0044] During disassembly, rotate the fastener 6 in the opposite direction to fully retract it into the cavity of the protrusion 5, and then release the pressure on the fastener 3 to separate the middle frame 2 assembly.

[0045] Compared with the prior art, the present invention has the following advantages: This intelligent touch switch fixing component is easy to assemble using fasteners 3, allowing for easy disassembly while ensuring a firm and secure fit. Welding is avoided. When assembling the middle frame 2 and the base 4, the middle frame 2 is fastened to the top surface of the base 4. Force is then applied to the fasteners 3, causing them to bend and press against a predetermined protrusion 5 on the side of the base 4. Specifically, the fasteners 3 press against the side and bottom of the protrusion 5. The protrusion 5 is hollow; a movable column 8 is used to rotate out the fan-shaped fastener 6 inside the protrusion 5. The back of the fastener 6 is movably connected to the front of the fastener 3, locking the fastener 3 onto the protrusion 5, thus achieving a firm yet detachable assembly of the middle frame 1 and the base 4.
