Description

Technical Field

[0001] This utility model relates to the technical field of smart home, and in particular to a home control device. Background Technology

[0002] In existing technologies, traditional sofa hand controller designs typically fail to fully optimize installation space, resulting in a large required base area for installation. When such hand controllers need to be directly mounted on the sofa surface, the large installation area not only negatively impacts the sofa's overall appearance and visual aesthetics but also, by occupying excessive surface space or creating localized protrusions, may reduce user comfort when leaning against it. This conflict between space occupancy and stability limits the product's application flexibility and user experience, necessitating improvement. Utility Model Content

[0003] The main purpose of this utility model is to propose a home control device that aims to reduce the installation space required for home control devices and improve the application flexibility and user experience of home products.

[0004] To achieve the above objectives, this utility model proposes a home control device, which includes:

[0005] The upper shell has an external thread structure on its outer surface and a hollow groove.

[0006] The lower shell is fitted into the hollow groove; and

[0007] A nut, which is used to pass through the sofa mounting hole, has an internal thread structure that matches the external thread structure, so as to lock the nut with the upper shell and fix the home controller to the sofa surface.

[0008] In one embodiment, the end of the external thread structure is provided with a tapered inlet, and the tapered inlet has a taper angle of 15°-20°.

[0009] In one embodiment, a first boss is provided on the top of the nut, and a second boss is provided at the end of the upper shell away from the external thread structure. The second boss and the first boss form a clamping position, which is used to clamp the sofa leather to fix the hand controller on the sofa.

[0010] In one embodiment, the lower shell has a receiving cavity;

[0011] The home control device also includes:

[0012] A circuit board, disposed within the receiving cavity, is used to generate control signals; and

[0013] A light-transmitting button is disposed on the surface of the upper shell and electrically connected to the circuit board.

[0014] In one embodiment, the top of the receiving cavity is provided with a slot for fixing the circuit board so that the circuit board is electrically connected to the light-transmitting button.

[0015] In one embodiment, the edge of the base is made of a light-transmitting material, and an LED light strip is integrated on the inner side of the base to emit low-brightness light to form a positioning light effect for the hand controller.

[0016] In one embodiment, the surface of the translucent button is provided with a laser-engraved pattern, which forms a functional identifier that is visible at night when the light is transmitted.

[0017] In one embodiment, the home controller further includes an LED light source disposed within the receiving cavity, the LED light source being electrically connected to the circuit board, and the light from the LED light source penetrating the laser-engraved pattern of the translucent button to achieve nighttime positioning.

[0018] In one embodiment, the outer surface of the nut is provided with anti-slip texture to enhance friction when manually tightening.

[0019] The technical solution of this utility model provides a home hand controller comprising an upper shell, a lower shell, and a nut. The outer surface of the upper shell has an external thread structure and a hollow groove. The lower shell is embedded in the hollow groove. The nut is locked in place by the engagement of the internal and external thread structures, thus fixing the hand controller to the sofa surface. Through the axial locking mechanism of the internal and external thread structures, the threaded engagement structure allows the hand controller to adapt to the mounting hole, transforming the fixed contact surface from a plane to a line contact. This effectively reduces the area occupied by the base surface, shrinking the installation space of the home hand controller. After installation, the shell surface is flush with the sofa contact surface, eliminating the impact of the protruding structure on user comfort in traditional solutions, thereby improving the application flexibility and user experience of the home product.

[0031] In existing technologies, traditional sofa hand controllers require a large base area for installation. This design not only disrupts the overall appearance of the sofa but also creates noticeable protrusions on the surface. When a user leans against the sofa, the protruding structure may affect the flatness of the contact surface, and the excessively large installation area limits the flexible placement of the hand controller in different positions on the sofa.

[0032] To address these issues, researchers discovered structural redundancy in traditional hand controller mounting methods. By analyzing the dimensional characteristics of the sofa mounting holes, they attempted to decompose the hand controller into combinable, independent components. Leveraging the adjustable nature of the threaded connection structure, they explored replacing the traditional planar fixing method with axial locking, thereby reducing lateral space occupation.

[0033] Therefore, please refer to Figures 1 to 4 This application proposes a home hand controller comprising an upper shell 10, a lower shell 20, and a nut 30. The outer surface of the upper shell 10 is provided with an external thread structure 10a and a hollow groove is formed. The lower shell 20 is embedded in the hollow groove. The nut 30 is locked by the cooperation of the internal thread structure 30a and the external thread structure 10a, so that the hand controller is fixed to the surface of the sofa.

[0034] The external thread structure 10a refers to a spiral protrusion extending continuously along the outer circumference of the cylinder, which can be implemented using a single-start trapezoidal thread, and its lead parameter can be adapted to the thickness of the sofa mounting holes. The hollow groove refers to a cavity structure penetrating the axial direction of the housing, which can be formed through injection molding and is used to support the lower housing 20 assembly. The mounting method refers to the assembly of the lower housing 20 with the hollow groove through interference fit or snap-fit ​​structure, specifically using a locating boss and guide groove mating structure to achieve axial positioning.

[0035] Specifically, during installation, the lower shell 20 assembly is inserted into the hollow groove of the upper shell 10, and the nut 30 is screwed into the external thread structure 10a after passing through the sofa mounting hole. As the thread engagement depth increases, the nut 30 and the upper shell 10 generate an axial clamping force, clamping the edge of the sofa mounting hole between them. This axial locking method eliminates the need for a large-area fixing base on the sofa surface, and the threaded engagement structure can adapt to mounting holes of different thicknesses.

[0036] Compared to existing technologies, traditional hand controllers use planar bonding or screw penetration for fixing, requiring sufficient planar area to accommodate the adhesive or screw heads. This solution uses an axial locking mechanism with a threaded structure to transform the fixing contact surface from planar to line contact, effectively reducing the base surface area occupied and avoiding damage to the internal structure of the sofa caused by penetration installation.

[0037] Through the above technical solution, this application compresses the installation area of ​​the hand controller to a size range comparable to the sofa mounting holes while maintaining stability. The threaded fit structure allows the hand controller to adapt to the mounting holes, and after installation, the surface of the housing is flush with the contact surface of the sofa, eliminating the impact of the protruding structure on the user's leaning comfort in traditional solutions.

[0038] Please see Figure 1 and Figure 3 This application further proposes a home control device, wherein the end of the external thread structure 10a is provided with a tapered inlet, and the tapered inlet has a taper angle of 15°-20°.

[0039] The tapered guide section refers to the gradually narrowing inclined surface structure formed at the end of the external thread. This can be achieved through machining or injection molding. Its function is to guide the alignment of the internal thread structure 30a of the nut 30 with the external thread during initial engagement via its gradually narrowing geometric shape. The cone angle refers to the angle between the tapered guide section's inclined surface and the thread axis. This angle can be adjusted by changing the mold angle or machining parameters. This angle range is set as a key parameter balancing guide efficiency and structural strength.

[0040] Specifically, when the nut 30 is screwed in along the external thread, the tapered guide portion first contacts the edge of the internal thread structure 30a of the nut 30, using the guiding effect of the inclined surface to gradually align the thread profile. When the tapered angle is controlled within the range of 15°-20°, it avoids multiple alignment adjustments caused by an excessively small angle, while also preventing insufficient bearing area at the beginning of the thread due to an excessively large angle. This design allows for rapid positioning during installation without the need for auxiliary tools, while ensuring the effective contact length of the thread engagement section.

[0041] Compared to existing technologies, traditional hand controllers typically use right-angled end faces or simple chamfered structures for their external threads. During installation, the initial engagement position of the nut 30 and the thread needs to be repeatedly adjusted, which can easily lead to thread damage due to misalignment. In contrast, the tapered guide section significantly reduces the difficulty of alignment through its tapered guiding structure, making the installation operation smoother and avoiding the risk of deformation caused by stress concentration at the beginning of the thread.

[0042] Through the above technical solution, this application effectively solves the problem of low assembly efficiency caused by difficulty in thread alignment during the installation of the hand controller, reduces thread wear caused by installation misalignment, and ensures reliable locking of the external thread and nut 30. This structure simplifies the installation steps while maintaining the compactness of the overall structure, avoiding an increase in the size of the hand controller due to complicated installation operations.

[0043] Please see Figure 1 and Figure 3This application further proposes that the nut 30 has a first boss 30c on its top and a second boss 10b is provided at the end of the upper shell 10 away from the external thread structure 10a. The second boss 10b and the first boss 30c form a clamping position, which is used to clamp the sofa leather to fix the hand controller on the sofa.

[0044] The nut 30 of the hand controller is one of the key components of this structure, and its top is designed with a first boss 30c. The first boss 30c is annular in shape and is evenly distributed around the central axis of the nut 30. Its inner diameter matches the external thread of the nut 30, ensuring that the normal tightening function of the nut 30 is not affected, while providing support for the clamping function. The upper shell 10 of the hand controller is another key component, and its end away from the external thread structure 10a is provided with a second boss 10b. The second boss 10b is also annular in structure, and its inner diameter is connected to the main body of the upper shell 10. The design fully considers the assembly relationship with the nut 30, so that the two can form an effective clamping position.

[0045] When the nut 30 is assembled with the upper shell 10, the first boss 30c and the second boss 10b cooperate to form a clamping position. The gap of this clamping position can be finely adjusted by adjusting the engagement depth of the nut 30 to accommodate sofa leather of different thicknesses. The clamping position is an annular groove shape, which can provide sufficient clamping force for the sofa leather and ensure the stability of the hand controller on the sofa.

[0046] When attaching the hand controller to the sofa, first place the sofa leather at the clamping position formed by the second protrusion 10b and the first protrusion 30c. Since the shape of the clamping position matches the edge of the sofa leather, it can well accommodate the sofa leather, thus initially positioning it. By tightening the nut 30, the distance between the first protrusion 30c and the second protrusion 10b gradually decreases, thereby applying pressure to the sofa leather. As the nut 30 is further tightened, the clamping force at the clamping position gradually increases, eventually firmly clamping the sofa leather between the two protrusions. At this point, the hand controller achieves a stable connection with the sofa by clamping the sofa leather, preventing it from easily loosening or shifting due to external forces. When it is necessary to disassemble the hand controller, simply loosen the nut 30 in the opposite direction; the clamping force between the first protrusion 30c and the second protrusion 10b gradually decreases, and the sofa leather can be removed from the clamping position, thus easily completing the disassembly operation of the hand controller.

[0047] This embodiment cleverly forms a clamping position for clamping sofa leather by setting a first boss 30c on the top of the nut 30 and a second boss 10b at the end of the upper shell 10. It is not only simple in structure and ingenious in design, but also easy to operate. It can effectively improve the fixing stability of the hand controller on the sofa and has good practicality and market application prospects.

[0048] Please see Figure 1 and Figure 3 This application further proposes a home control device including a lower shell 20, the lower shell 20 having a receiving cavity 20a; a circuit board 40 disposed in the receiving cavity 20a for generating control signals; and a light-transmitting button 50 disposed on the surface of the upper shell 10 and electrically connected to the circuit board 40.

[0049] The cavity 20a refers to the enclosed space formed inside the lower shell 20, which can be achieved using injection molding. It is used to centrally mount the circuit board 40 and related electronic components, reducing external space occupation. The circuit board 40 is a printed circuit board with electronic components, which can be achieved using surface mount technology. It is used to convert button operations into electrical signals to control home appliances. The light-transmitting button 50 is an operating component with light-transmitting capabilities. It can be made of polycarbonate material and has conductive contacts inside that are connected to the circuit board 40, enabling touch control while allowing light transmission.

[0050] Specifically, the receiving cavity 20a forms an independent installation space through the structural design of the lower shell 20, and the circuit board 40 is fixed within this space to avoid interference with external mechanical components. A light-transmitting button 50 covers the surface of the upper shell 10; its light-transmitting properties allow internal light sources to penetrate the button to form visual indicators, while the button's touch signals are transmitted to the control terminal via the circuit board 40. This layout integrates electronic components inside the lower shell 20, reducing the overall thickness of the hand controller and minimizing the protrusion height of the mounting area on the sofa surface.

[0051] Compared with existing technologies, the dispersed arrangement of electronic components in traditional hand controllers leads to an increase in the size of the casing. In contrast, this solution centrally mounts the circuit board 40 in the housing cavity 20a, combined with the thin design of the light-transmitting buttons 50, which significantly reduces the size of the mounting base while maintaining the integrity of the function, thus avoiding negative impacts on the appearance of the sofa and the user's comfort.

[0052] Through the above technical solution, this application achieves high-density integration and thin layout of electronic components, completes signal control and tactile feedback functions within a limited installation space, and improves the convenience of nighttime operation by utilizing the optical characteristics of the light-transmitting button 50, thus solving the contradiction between installation stability and space occupation caused by the excessive size of traditional hand controllers.

[0053] Please see Figure 1 and Figure 3 This application further proposes that the top of the receiving cavity 20a of the home controller is provided with a slot 20b, which is used to fix the circuit board 40 so that the circuit board 40 is electrically connected to the light-transmitting button 50.

[0054] In this embodiment, the slot 20b refers to the limiting structure located at the top of the receiving cavity 20a. Specifically, it can adopt a groove design with elastic claws or directly set an annular groove on the side wall of the receiving cavity 20a near the light-transmitting button 50. The circuit board 40 is fixed by clamping the edge of the circuit board 40 or limiting the edge of the groove wall, so as to prevent the circuit board 40 from being displaced in the vibration environment.

[0055] Specifically, the slot 20b at the top of the receiving cavity 20a matches the external dimensions of the circuit board 40. After the circuit board 40 is inserted into the slot 20b, it is restrained by elastic claws around its perimeter, thus maintaining stability. This structure eliminates the need for additional screws or glue to fix the circuit board 40, simplifying the assembly process.

[0056] Through the above technical solution, this application achieves reliable fixation of the circuit board 40 within a limited space, while optimizing the assembly efficiency of the housing. The design of the slot 20b avoids poor contact problems caused by external impacts on the circuit board 40, thereby improving the long-term stability of the hand controller in sofa installation scenarios.

[0057] Please see Figure 1 and Figure 3 This application further proposes that the base edge is made of a light-transmitting material and that an LED light strip is integrated on the inner side of the base to emit low-brightness light to form a positioning light effect for the hand controller outline.

[0058] The light-transmitting material refers to a non-metallic material that allows light to pass through and provides structural support; specifically, polycarbonate or acrylic materials can be used. This material maintains the mechanical strength of the base while evenly diffusing the light emitted by the LED strip, preventing localized bright spots from interfering with visual perception.

[0059] LED light strips are flexible circuit components composed of multiple miniature light-emitting diodes arranged linearly. Specifically, they can be implemented using a combination of surface-mount LEDs and a flexible PCB board. The light strip is integrated into the inner edge of the base, and the luminous intensity is adjusted to a suitable lumen range through a control circuit, producing soft ambient light at night, which meets the needs of contour recognition while avoiding strong light that may disturb the user's rest.

[0060] Specifically, the base, as part of the lower housing 20, has a light-transmitting edge that works in conjunction with the inner LED light strip. When the circuit board 40 supplies power to the LED light strip, the light is scattered outward through the light-transmitting material, creating a continuous halo effect on the outer edge of the base. The coverage of this halo can extend to the entire outline of the base, allowing the controller to be quickly identified in dark environments. The light strip's power supply mode can be set to always-on or touch-activated, such as triggering illumination via an infrared sensor when a user approaches.

[0061] Compared to existing technologies, traditional handheld controllers rely heavily on external auxiliary light sources or additional indicator lights for nighttime positioning, resulting in complex structures and additional space requirements. This solution integrates material properties with the lighting components to achieve positioning within the existing base structure, without altering the outer shell size or adding protruding parts, effectively maintaining the flatness of the sofa surface.

[0062] Through the above technical solution, this application can provide non-invasive contour positioning lighting effects at night, helping users quickly identify the location of the controller. The light diffuses evenly through the translucent material, forming a soft edge glow, avoiding direct light from stimulating the user's vision. This lighting effect achieves positioning functionality without compromising the overall appearance of the sofa, and the combination of the translucent base and LED light strip reduces space requirements compared to traditional independent lighting components.

[0063] Please see Figure 1 and Figure 3 This application further proposes that the surface of the translucent button 50 is provided with a laser-engraved pattern, which forms a functional mark that is visible at night when the light is transmitted.

[0064] Laser engraving refers to graphic markings created on the button surface using laser engraving technology, combining translucent and non-translucent areas. Specifically, this can be achieved by using a carbon dioxide laser to engrave at a micron-level depth on the polycarbonate surface, creating a difference in light transmittance between the engraved and non-engraved areas. The nighttime visibility of these markings occurs when the backlight is activated, allowing light to penetrate the laser-engraved area and create a contrasting graphic or text display on the button surface. The amount of light transmission can be controlled by adjusting the engraving depth.

[0065] Specifically, when the circuit board 40 controls the LED light source to start, light is transmitted upward from the receiving cavity 20a of the lower shell 20, passing through the laser-engraved pattern area of ​​the translucent button 50. Because the light transmittance differs between the laser-engraved and non-laser-engraved areas, high-contrast functional markings, such as directional arrows or text symbols, are formed on the button surface. In low ambient light, users can directly operate the buttons by recognizing the self-illuminating markings, without relying on external lighting equipment.

[0066] Compared to existing technologies, traditional hand controllers typically use screen printing or engraving for button markings, which require an external light source to be visible at night. In contrast, laser engraving combined with backlighting allows the markings to glow in low light conditions, preventing users from making mistakes due to not being able to see the markings.

[0067] Through the above technical solution, this application achieves clear visibility of the hand controller function markings in nighttime environments, solves the problem of traditional products relying on ambient light, and avoids the impact of adding external lighting components on the integrity of the sofa's appearance.

[0068] Please see Figure 1 and Figure 3 This application further proposes that the home controller also includes an LED light source disposed in the receiving cavity 20a, the LED light source being electrically connected to the circuit board 40, and the light from the LED light source penetrating the laser-engraved pattern of the translucent button 50 to achieve nighttime positioning.

[0069] The LED light source refers to the light-emitting component installed within the housing cavity 20a, which can be implemented using surface-mount LED beads. It is powered and its light-emitting mode is controlled by the circuit board 40. The housing cavity 20a refers to the enclosed space formed inside the lower shell 20, which can be formed using injection molding to integrate electronic components and isolate it from the external environment. The electrical connection of the circuit board 40 refers to the electrical conduction achieved through metal wires or flexible circuit boards, which can be fixed by soldering or plugging, and is used to synchronously control the on / off state of the LED light source. The laser-engraved pattern on the translucent button 50 refers to a semi-transparent mark formed by laser engraving. Specifically, the button substrate can be made of polycarbonate material, and a texture with varying light transmittance can be formed on the surface using laser technology.

[0070] Specifically, the LED light source is positioned at the edge of the circuit board 40, and its light is evenly diffused to the bottom of the translucent button 50 through a light guide structure. When the circuit board 40 detects that the ambient light intensity is lower than a set threshold, it automatically triggers the LED light source to operate in low-power mode. After the light penetrates the laser-engraved pattern, it forms a contrasting graphic on the button surface, allowing users to intuitively identify the button's function area in a dark environment.

[0071] In some specific implementations, the LED light source can use a warm white light-emitting chip to reduce glare, while the circuit board 40 can integrate a photosensor module to automatically adjust the light emission brightness according to changes in ambient light. The light-transmitting area of ​​the laser-engraved pattern can be designed as the outline of a functional symbol, for example, using an arrow-shaped light-transmitting strip to indicate the adjustment direction.

[0072] Compared to existing technologies, traditional hand controllers rely on external lighting or fluorescent coatings for nighttime recognition, which suffers from dependence on external conditions or easy wear and tear on the markings. This solution, through the synergy of a built-in light source and a light-transmitting structure, achieves all-weather visual operation guidance while maintaining the compact structure of the hand controller.

[0073] Through the above technical solution, this application effectively solves the problem that the function markings of traditional hand controllers are not visible in low light environments. By integrating the light-emitting components and the design of the light-transmitting buttons, the self-illuminating positioning function of the operating interface is realized without the need to add external auxiliary devices. This not only avoids the occupation of installation space due to structural complexity, but also ensures the accuracy and convenience of users' operation at night.

[0074] Please see Figure 2 and Figure 3 This application further proposes that the outer surface of the nut 30 is provided with anti-slip texture 30b to enhance the friction when manually tightening.

[0075] The anti-slip texture 30b refers to the raised and recessed texture distributed on the outer surface of the nut 30. This can be achieved through knurling or diamond embossing, increasing the coefficient of friction on the contact surface and providing the operator with a stronger grip when manually rotating the nut 30. Knurling creates regularly arranged raised patterns by pressing intersecting or parallel lines onto the metal surface, while diamond embossing uses a die to create a grid-like raised and recessed structure. Both methods effectively improve surface roughness.

[0076] Specifically, the anti-slip texture 30b on the outer surface of the nut 30 comes into contact with the operator's fingers during installation. By increasing the micro-friction resistance of the contact surface, it prevents slippage caused by wet hands or deviations in the applied force angle. When the operator applies rotational torque, the raised parts of the texture embed into the skin surface, forming a multi-point engagement effect, making the rotational action easier to transmit to the thread structure and ensuring that the nut 30 is stably screwed in axially.

[0077] Compared to existing technologies, the outer surface of the mounting nut 30 in traditional hand controllers is typically a smooth plane or a simple annular groove. During manual operation, insufficient friction can easily lead to failure in applying force, especially in confined spaces or single-handed operation scenarios, potentially causing reduced installation efficiency or thread misalignment. This solution, through the optimized physical structure of the anti-slip texture 30b, directly improves operational reliability and reduces torque loss caused by slippage during installation.

[0078] Through the above technical solution, this application effectively improves the ease of operation during the installation of the hand controller, ensures the quick and accurate alignment of the nut 30 and the upper shell 10 threads, avoids wear on the mounting surface caused by repeated adjustments, reduces the risk of thread deformation caused by uneven force application, and improves the stability of the hand controller fixed on the sofa surface.

[0079] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
