Description

Technical Field

[0001] This invention belongs to the field of smart home control technology, and in particular to a smart home control device with combined rotary button sensing. Background Technology

[0002] With the rapid development of IoT technology and the continuous expansion of the smart home market, smart home control systems, as the core interface for user interaction with home devices, are receiving increasing attention from the industry for their design and functional innovation. Smart home control systems typically use knobs, buttons, and other interactive methods to achieve scenario-based control of home devices such as curtains, underfloor heating, and ventilation systems. These controllers generally communicate with the controlled devices via the RS-485 or KS protocol, thereby achieving unified management of various home devices. However, existing smart home controllers generally suffer from monotonous and rudimentary designs. Traditional knob and button devices, due to structural limitations, often struggle to balance functionality with aesthetics and decoration. Specifically, existing knob and button controllers typically employ simple mechanical structures, lacking a sense of layering and refinement in their external appearance, failing to meet the increasingly sophisticated aesthetic demands of modern consumers for smart home products. Furthermore, while some controllers incorporate lighting indicators, the arrangement and guidance of the lights lack proper planning, easily leading to uneven illumination and dark areas, negatively impacting the product's visual appeal and user experience.

[0003] A search revealed a control device for a smart home system, patent CN217983173U. This patent utilizes an encoder with button functionality. The encoder includes a control column, a code disk mounted on the control column, and a chassis that fixes the control column and code disk. It allows adjustment of the control device's operating mode parameters by rotating the code disk, and selection of the operating mode by pressing a button on the encoder. However, this technical solution has several shortcomings: First, the encoder structure is directly exposed, with a simple design lacking aesthetic appeal, making it difficult to meet users' aesthetic demands for product appearance. Second, the integration of knob and button functions on the same encoder can easily affect the accuracy of rotational adjustment during pressing, resulting in a less than ideal user experience. Third, this solution lacks any light-guiding structure, failing to improve visual feedback.

[0004] A search revealed a patent, CN117040519A, concerning a smart home control method, smart home system, and computer-readable storage medium based on a knob device. This patent employs a scheme where the knob encoder and button are separately configured. The knob encoder generates pulse signals on the first and second channels, while the button generates a first signal on the third channel. By judging the formation time and duration of the pulse signals, it achieves the recognition of complex operations such as long-press and rotation. However, this technical solution has the following shortcomings: First, it only involves improvements to the control method without any optimization of the controller device's appearance or structure, resulting in a monotonous and unattractive product design. Second, the separate configuration of the knob and button leads to a large area occupied by the control panel, hindering miniaturization and integration. Third, this solution does not involve any lighting guidance or visual effect enhancement techniques, failing to meet users' aesthetic requirements.

[0005] The aforementioned existing technical solutions demonstrate that while current smart home controllers achieve knob rotation control and multi-button composite sensing functions, they struggle to simultaneously maintain a pleasing aesthetic and visual appeal, resulting in issues such as monotonous structure, rudimentary design, and poor lighting effects. Therefore, how to further enhance the aesthetic and visual appeal of smart home controllers while achieving knob rotation control and multi-button composite sensing functions, thus combining functionality and beauty, has become a pressing technical challenge in the field of smart home control. Summary of the Invention

[0006] The purpose of this invention is to provide a smart home control device with combined rotary button sensing to solve the problems mentioned in the background art.

[0012] Preferably, a decorative ring is fixed to the inner side of the outer ring, and a transparent light guide ring is snapped onto the top of the outer ring and located between the decorative ring and the first receiving groove. A flexible coil is pasted on the outer periphery of the base component, and multiple LED beads are arranged in a ring array on the top surface of the flexible coil. The light emitted by the LED beads is refracted by the outer edge of the base component and then transmitted to the transparent light guide ring.

[0013] Preferably, the LED bead and the transparent light guide ring are positioned opposite each other, and the light sequentially forms a first refraction point through the outer edge of the base component and a second refraction point through the bottom surface of the transparent light guide ring, and is finally transmitted upward to the surface of the transparent light guide ring.

[0014] Preferably, the bearing is an H-type deep groove ball bearing, with its inner ring fixed to the outer periphery of the inner liner fixing member and its outer ring fixed to the inner wall of the rear cover.

[0015] Preferably, a bottom cover is installed on the bottom surface of the base shell, and a wireless charging panel is provided in the middle of the bottom cover. A reset plate and a wireless coil plate are provided at the bottom of the inner cavity of the base shell. The wireless coil plate is located on the back of the wireless charging panel. The bottom of the tray component has a downward convex disc-shaped structure. The bottom support component has a stepped platform inside that cooperates with it. The two are fixed by adhesive. When the glass cover is pressed, the bottom support component moves down, causing the cross protrusion to trigger the micro switch.

[0016] Preferably, the assembly includes a mounting base and a rear cover, a coupler, an upper magnet box, a lower magnet box, and a pin header seat disposed within the mounting base. The rear cover is located in the upper part of the mounting base cavity and houses the coupler.

[0017] Compared with the prior art, the technical effects and advantages of the present invention are as follows: This smart home control device with rotary button composite sensing significantly enhances the device's appearance and decoration by setting a first receiving groove filled with decorative diamonds on the top of the outer ring, setting multiple second receiving grooves filled with decorative diamonds or potting compound on the bottom surface of the inner cavity of the tray component, and a serrated decorative structure. This overcomes the shortcomings of the monotonous appearance of traditional smart home controllers. By designing a refractive light transmission path for the LED beads, the point light source is transformed into a surface light source after multiple refractions, effectively avoiding the problems of exposed bright spots and uneven brightness. At the same time, by setting up three power supply methods—battery power supply, Type-C wired charging, and wireless charging—users can flexibly choose according to their actual usage scenarios, greatly improving the convenience of device maintenance and the flexibility of use. The rotary sensing function of the knob is realized through the rotating structure supported by the bearing and the detection mechanism of the photoelectric sensor, and the button pressing sensing function is realized through the cross-shaped protrusion supported by the elastic arm and the micro switch. This device integrates knob adjustment and button control, meeting the needs of various interactive operations in smart home scenarios. The wall-mounted version greatly simplifies the construction difficulty of wall installation through magnetic positioning and pin connection. Attached Figure Description

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this invention, and are explained here together.

[0024] like Figures 1 to 13 As shown, this invention provides a smart home control device with combined knob and button sensing. This device can be used to control smart home scenarios such as curtains, underfloor heating, and fresh air systems, and communicates with external devices via RS485 or KS protocols to achieve centralized control and management of the smart home system. The combined knob and button sensing control device of this invention has an overall cylindrical structure, mainly including an outer ring 1 and a base shell 2 located below the outer ring 1. A bottom cover 7 is installed on the bottom surface of the base shell 2, and a wireless charging panel 8 is located in the middle of the bottom cover 7. After removing the bottom cover 7, a reset plate 9 and a wireless coil plate 10 are located at the bottom of the inner cavity of the base shell 2. The wireless coil plate 10 is located on the back of the wireless charging panel 8. This overall cylindrical structure design is not only aesthetically pleasing but also facilitates knob rotation and button pressing operations, conforming to ergonomic design principles and providing a comfortable operating experience for users. Example 1

[0025] refer to Figure 1 , Figure 2 and Figure 4 The outer ring 1 has a first receiving groove 6 integrally formed on the top inner side, which is filled with decorative parts made of decorative diamonds. The filling of decorative diamonds gives the device a dazzling visual effect, greatly enhancing the product's sense of quality and artistic flair. A decorative ring 4 is fixed to the inner side of the outer ring 1. The decorative ring 4 is made of metal and electroplated. The electroplating process forms a bright metallic coating on the surface of the decorative ring 4, which not only enhances its corrosion resistance and wear resistance but also gives it a high-end metallic texture, complementing the decorative diamonds and further enhancing the overall visual effect of the device. A transparent light guide ring 5 is fixedly installed on the top of the outer ring 1 between the decorative ring 4 and the first receiving groove 6 by a snap-fit ​​method. The transparent light guide ring 5 is made of transparent or semi-transparent material. The function of the transparent light guide ring 5 is to receive the light emitted from the lower LED 20 and guide the light so that the light shines evenly from the surface of the transparent light guide ring 5, thereby realizing the function of indicating the open or closed status of the button on the glass cover 3, or realizing various dazzling lighting effects to create the effect of home ambient lighting.

[0026] Further, refer to Figure 1 , Figure 2 and Figure 11A glass cover plate 3 is installed inside the outer ring 1 and on the bottom surface of the decorative ring 4 by pressing down. The glass cover plate 3 is made of fully transparent glass, and its surface is decorated with function icons. These icons indicate specific functions of the corresponding buttons on the glass cover plate 3, such as opening or closing curtains, adjusting underfloor heating, controlling fresh air, or switching to a preset scene. Users can clearly understand the control function of each button by observing the function icons. The fully transparent glass cover plate 3 design allows users to observe the lighting effects inside the device from multiple angles. Furthermore, the function icons are formed on the surface of the glass cover plate 3 using silkscreen or other printing processes, ensuring the icons are clear and durable.

[0027] Further, refer to Figure 1 , Figure 7 and Figure 11 A tray component 21 is disposed directly below the glass cover plate 3. The tray component 21 adopts a disc-shaped structure design. Multiple second receiving grooves 22 are integrally formed on the bottom surface of the inner cavity of the tray component 21. The multiple second receiving grooves 22 are all arranged concentrically with the tray component 21, and the radius of the multiple second receiving grooves 22 is different, presenting a concentric ring distribution with the radius gradually increasing from the inside to the outside. The multiple second receiving grooves 22 are filled with decorative filler, which is made of decorative diamonds or potting compound. When decorative diamonds are used, the decorative diamonds in the second receiving grooves 22 echo the decorative diamonds in the first receiving grooves 6, forming a multi-layered and multi-dimensional visual decorative effect. When potting compound is used, it can seal and protect the electronic components inside the tray component 21, and the transparency of the potting compound can also present an optical effect. The tray component 21 also features an integrally formed recess at the center of its inner bottom surface for placing decorative diamonds. This recess design ensures the diamonds are stably positioned, preventing displacement or detachment during use. The inner wall of the tray component 21 is decorated with a serrated decorative structure made of aluminum alloy. This serrated structure creates rich light and shadow variations under illumination, further enhancing the device's visual appeal and three-dimensionality. This purely decorative design completely overcomes the monotonous appearance of traditional smart home controllers, giving the device a refined and luxurious visual effect that meets the aesthetic demands of high-end smart home scenarios.

[0028] Further, refer to Figure 8 , Figure 9 and Figure 11Below the tray component 21, there is a base support component 23. The base support component 23 is made of a plastic part with an elastic arm 25. The bottom of the tray component 21 has a downward convex disc-shaped structure. The interior of the base support component 23 has a stepped platform for supporting the downward convex disc-shaped structure. The design of the stepped platform allows the bottom of the tray component 21 and the base support component 23 to fit together precisely. After fitting, the two are firmly connected by adhesive. The adhesive fixing method not only has a firm and reliable connection, but also effectively prevents moisture and dust from entering the connection gap, thereby improving the sealing performance and service life of the device.

[0029] Further, refer to Figure 8 , Figure 9 and Figure 11 Four mounting notches 24 are arranged in a ring array on the bottom surface of the inner cavity of the base component 23. Each mounting notch 24 is integrally connected to an elastic arm 25. The four elastic arms 25 are arranged in a cross shape, with one end of each arm being a fixed end and the other end being a free elastic end. The fixed end of the elastic arm 25 is integrally connected to the bottom wall of the inner cavity of the base component 23, while the free elastic end can undergo elastic deformation. A screw hole is integrally formed on the top surface of the free elastic end of each elastic arm 25. A circuit board 16 is located directly below the base component 23 and is fixedly connected to the screw hole of the elastic arm 25 by screws. A micro switch is provided on the circuit board 16, and the micro switch is arranged opposite to the free elastic end of the elastic arm 25.

[0030] Further, refer to Figure 9 and Figure 11 A cross-shaped protrusion 26 is provided on the bottom surface of the base component 23, between each of two adjacent elastic arms 25. The four cross-shaped protrusions 26 are also arranged in a cross shape, and their positions correspond to the positions of the microswitches on the circuit board 16. Since the fixed end of the elastic arm 25 is fixed to the base component 23 while its free end is fixedly connected to the circuit board 16, the elastic arm 25 provides support and guidance during button pressing, allowing the base component 23 to undergo slight displacement relative to the circuit board 16. When the user presses the button on the surface of the glass cover 3, the pressing force is transmitted through the glass cover 3 to the tray component 21 and the base component 23. Under the pressing force, the base component 23 undergoes a downward micro-displacement, causing the cross-shaped protrusions 26 to move downwards and trigger the microswitches on the circuit board 16 below, thus generating a button signal. Due to the elastic characteristics of the elastic arm 25, the cross-shaped protrusions 26 can move slightly up and down, triggering the microswitches when pressed and returning to their original position after release due to the elastic restoring force of the elastic arm 25. The design principle of this button triggering structure is to achieve the triggering action by fixing the elastic arm 25 and the circuit board 16, and only pressing the button. This avoids the problem of poor contact or unreliable triggering caused by the simultaneous movement of the button and the circuit board in the traditional button structure, and ensures the sensitivity and reliability of button triggering.

[0031] Further, refer to Figure 6 , Figure 10 and Figure 12 A flexible coil 19 is attached to the outer edge of the base component 23. Multiple LED beads 20 are mounted in a circular array on the top surface of the flexible coil 19, evenly distributed around its circumference. The LED beads 20 are directly opposite the transparent light guide ring 5 above them, but the light emitted by the LED beads 20 does not directly reach the transparent light guide ring 5. The innovative design of this invention is that the light emitted by the LED beads 20 is first obliquely emitted to the outer edge of the base component 23, forming a first refraction point A on the outer edge of the base component 23; then, it is obliquely refracted from the first refraction point A to the bottom surface of the transparent light guide ring 5, forming a second refraction point B on the bottom surface of the transparent light guide ring 5; finally, it continues to obliquely refract upwards from the second refraction point B to form a light spot C, which is then conducted to the surface of the transparent light guide ring 5. After the light undergoes a first refraction at the outer edge of the base component 23 and a second refraction at the bottom surface of the transparent light guide ring 5, the originally concentrated point light source diffuses into a uniform surface light source, resulting in a softer and more uniform light emission effect. This effectively avoids the visual defects of directly exposed LED bright spots and uneven brightness caused by traditional direct light guiding methods. The bottom of the flexible coil 19 is connected to the connector 17 on the top surface of the circuit board 16 via a flexible cable 18, achieving electrical connection. The control signals on the circuit board 16 are transmitted to the flexible coil 19 through the connector 17 and the flexible cable 18, thereby controlling the light emission state and color change of the LED 20.

[0032] Further, refer to Figure 3 , Figure 5 and Figure 11 A liner fastener 13 is located directly below the circuit board 16. The liner fastener 13 is made of plastic and its function is to fix the circuit board 16 and the inner ring assembly connected to the elastic arm 25, so that the liner fastener 13 is connected to the base shell 2 as a whole, thereby achieving a fixed effect. The liner fastener 13 is fixed to the seat on the upper part of the inner cavity of the base shell 2 through its upper structure, so that the liner fastener 13 and the base shell 2 remain in a relatively static state.

[0033] Further, refer to Figure 4 , Figure 5 and Figure 11The outer ring 1 can rotate relative to the base shell 2. A rear cover 12 is fixedly connected to the bottom end of the outer ring 1 by screws. The rear cover 12 has a T-shaped disc structure, and its lower part is accommodated within the inner cavity of the base shell 2. The bottom end of the rear cover 12 extending into the inner cavity of the base shell 2 is connected to the inner liner fixing member 13 via a bearing 14. The bearing 14 is an H-type deep groove ball bearing, and its inner ring is fixedly connected to the outer ring of the inner liner fixing member 13 by an interference fit. The outer ring of the bearing 14 is also fixedly connected to the inner wall of the rear cover 12. When the outer ring 1 rotates, it causes the rear cover 12 to rotate around the inner liner fixing member 13 under the support of the bearing 14. The use of the bearing 14 ensures the smoothness and stability of the rotational movement.

[0034] Further, refer to Figure 5 and Figure 11 The rotation signal is detected by a photoelectric sensor 15. The bottom end of the photoelectric sensor 15 is inserted through the inner lining fastener 13 and extends downwards onto a circuit board 16, which provides power and signal transmission channels for the photoelectric sensor 15. A scanning window is provided on the inner lining fastener 13, through which the photoelectric sensor 15 scans the travel changes of the side wall of the back cover 12. A coding structure corresponding to the rotation angle is provided on the side wall of the back cover 12. When the user rotates the outer ring 1, the outer ring 1 drives the back cover 12 to rotate together. The coding structure on the side wall of the back cover 12 changes position relative to the scanning window of the photoelectric sensor 15. The photoelectric sensor 15 detects this change and generates a corresponding electrical signal. The circuit board 16 processes this signal to obtain information on the rotation angle and direction, thereby executing corresponding control commands to continuously adjust parameters such as the opening and closing degree of the curtains, the floor heating temperature, and the fresh air setting.

[0035] Further, refer to Figure 1 , Figure 2 and Figure 3A battery 11 is located in the lower part of the inner cavity of the base shell 2. The battery 11 provides power to the entire device and is one of the main power sources. A Type-C board 27 is embedded above the battery 11 and on the inner wall of the base shell 2. The Type-C board 27 has a Type-C charging interface. When the battery 11 is low on power, the user can connect the Type-C board 27 for wired charging via a Type-C charging cable. This design allows the user to continue charging even when the battery 11 is depleted. A bottom cover 7 is screwed onto the bottom surface of the base shell 2. A wireless charging panel 8 is located in the center of the bottom cover 7. A wireless coil board 10 is located on the back of the wireless charging panel 8. When wireless charging is needed, the user can align the bottom of the base shell 2 with the transmitting coil of a wireless charging device. The wireless coil board 10 senses the energy emitted by the external wireless charging device and converts it into electrical energy to charge the battery 11. Furthermore, a reset board 9 is located at the bottom of the inner cavity of the base shell 2. The reset board 9 is used to perform a system reset operation in case of device malfunction. The communication and power supply of circuit board 16 are connected to reset board 9, wireless coil board 10, and Type-C board 27 via ribbon cables. The power supply system of this invention consists of three power supply methods: wireless charging via wireless coil board 10, direct power supply via battery 11, and wired charging via Type-C board 27. Users can flexibly choose any one of these methods for power supply according to the actual usage scenario, which greatly improves the convenience of device maintenance and the flexibility of use. It is particularly suitable for applications in smart home scenarios where devices are deployed in a dispersed manner and frequent battery replacements are inconvenient. Example 2

[0036] This invention also provides a wall-mounted smart home control device with combined rotary button and sensor technology, see reference. Figure 13The wall-mounted device is basically the same as the upper structure of Embodiment 1, except that the lower part of Embodiment 1 adopts an independent structure of base shell 2 plus bottom cover 7, while the lower part of Embodiment 2 adopts a pre-embedded structure of mounting box 28. A rear cover seat 29 is provided on the upper part of the cavity of the mounting box 28, and a coupler is provided in the rear cover seat 29. The coupler is a key component for realizing electrical connection. An upper magnet box 30 and a lower magnet box 31 are respectively arranged opposite each other above the rear cover seat 29. Magnets are placed in both the upper magnet box 30 and the lower magnet box 31, and the two opposing magnets are magnetically attracted to each other. This magnetic attraction design is used to achieve quick positioning and firm fixation of the upper components. A pin header seat 32 is provided above the rear cover seat 29. The pin header seat 32 is plugged into the coupler through a pin header method to realize power supply, communication and charging functions. The bottom surface of the circuit board 16 is connected to the pin header seat 32 through a ribbon cable, and the pin header seat 32 is then plugged into the coupler through a pin header method. During installation, the mounting box 28 is first embedded in the wall. Then, the rear cover 29 and coupler are secured with screws. The upper component is then directly inserted into the mounting box 28 to complete the installation. The magnets in the upper magnet box 30 and lower magnet box 31 attract each other, ensuring accurate positioning and reliable connection of the upper component. The wall-mounted version significantly simplifies wall installation through magnetic positioning and pin header connection, making it particularly suitable for pre-installation during the renovation phase. Users simply insert the upper part of the controller into the pre-embedded mounting box; no complex wiring is required.

[0037] In practical applications, the smart home control device with combined knob and button sensing according to this invention allows users to trigger corresponding button actions by pressing the function icon area on the surface of the glass cover 3. The pressing force is transmitted through the glass cover 3 to the base component 23, causing the cross-shaped protrusion 26 to move down and trigger the micro switch to close. After detecting the button signal, the circuit board 16 sends control commands to external smart home devices via the RS485 protocol or KS protocol to control the on / off operation of devices such as curtains, underfloor heating, and fresh air systems. Simultaneously, users can adjust the device parameters by rotating the outer ring 1, for example, adjusting the temperature setting of the underfloor heating or the setting of the fresh air system. The outer ring 1 causes the back cover 12 to rotate, and the photoelectric sensor 15 detects the encoding change on the side wall of the back cover 12 and transmits the rotation information to the circuit board 16. The circuit board 16 then analyzes the rotation angle and sends corresponding adjustment commands to external devices. Regarding lighting indicators, users can select different lighting modes via a mobile app or the device panel. Circuit board 16 controls the illumination state of LED beads 20. The light emitted by LED beads 20 is refracted twice by the outer edge of the base component 23 and the bottom surface of the transparent light guide ring 5 before being evenly transmitted through the surface of the transparent light guide ring 5, providing users with soft and uniform visual feedback. Users can intuitively judge the current working status of the device based on the color and flashing pattern of the light. In terms of power supply, users can place the device on a wireless charging device for wireless charging, or charge it via a Type-C charging cable, or operate independently using the power of battery 11. These three power supply methods complement each other, ensuring continuous and stable operation of the device.

[0038] By setting a first receiving groove 6 filled with decorative diamonds at the top of the outer ring 1, setting multiple second receiving grooves 22 filled with decorative diamonds or potting compound on the bottom surface of the inner cavity of the tray component 21, and a sawtooth decorative structure, the appearance and decorative effect of the device are significantly enhanced. This changes the monotonous appearance of traditional smart home controllers, giving the device a rich sense of layering and a refined visual effect, meeting the aesthetic needs of high-end smart home scenarios. Through the refractive light transmission path design of the LED beads 20, the point light source is transformed into a uniform surface light source after being refracted twice by the outer edge of the base component 23 and the bottom surface of the transparent light guide ring 5. This effectively avoids the problem of exposed bright spots and uneven brightness of the LED beads, achieving a soft and uniform light guiding effect. By setting the battery 11 for power supply and Typ The e-C board 27 offers three power supply options: wired charging and wireless charging via the wireless coil board 10. Users can choose flexibly according to their actual usage scenarios, significantly improving the convenience of device maintenance and the flexibility of use. The rotary structure supported by the bearing 14 and the detection mechanism of the photoelectric sensor 15 enable the rotary sensing function of the knob. The cross-shaped protrusion 26 supported by the elastic arm 25, in conjunction with the micro switch, enables the button pressing sensing function. This device integrates knob adjustment and button control, meeting the needs of various interactive operations in smart home scenarios. The wall-mounted version simplifies the construction difficulty of wall installation and improves installation efficiency and reliability through the magnetic positioning of the upper magnet box 30 and the lower magnet box 31, combined with the pin connection method of the pin header 32 and the coupler.

[0039] It should be noted that the number of elastic arms 25 is not limited to four. It can be set to three, five, or other numbers depending on the actual number of buttons and the required trigger sensitivity, as long as the elastic support function for button triggering is achieved. The number and arrangement of LED beads 20 can also be adjusted according to the requirements of the light guiding effect. For example, a larger number of small-sized LED beads can be evenly distributed to obtain a more uniform light guiding effect. The type of bearing 14 is not limited to H-type deep groove ball bearings; as long as the outer ring can rotate smoothly relative to the base shell, it is acceptable. For example, needle roller bearings or other types of rotary support structures can be used.

[0040] It should be noted that, in this document, relational terms such as "one" and "two" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
