This can affect the normal operation of the module and even cause malfunctions such as short circuits. Especially in some humid environments or applications requiring waterproofing, such as outdoor equipment, kitchen appliances, and bathroom equipment, the waterproofing performance of traditional coded switch modules cannot meet the actual needs, limiting their application range.

[0004] Therefore, improvements to existing technologies are necessary.

After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0058] Please refer to Figure 1-3 This utility model provides a waterproof coded switch module. The core component of the waterproof coded switch module is a press-type faceplate assembly 1, which is composed of multiple key components, including a faceplate shell 101, a diaphragm 102, a lampshade 103, a PCB board 104, a faceplate bracket 105, and a waterproof adhesive layer 106.

[0059] Specifically, the faceplate housing 101 serves as the basic support structure for the entire press-fit faceplate assembly 1, and a carefully designed receiving cavity is provided inside. The purpose of this receiving cavity is to provide a stable mounting space for the diaphragm 102, lampshade 103, and PCB board 104, ensuring that these components can be arranged in an orderly manner inside the module and perform their respective functions.

[0060] The lampshade 103 plays a crucial role in the module, precisely covering the side of the PCB board 104 facing the bottom of the receiving cavity. This design not only protects the light-emitting elements on the PCB board 104 but also effectively guides light, enhancing the module's optical performance.

[0061] The diaphragm 102 is cleverly positioned between the inner bottom surface of the accommodating cavity and the lamp cover 103. The presence of the diaphragm 102 can play multiple roles such as buffering, isolation and protection. It can prevent wear caused by direct contact between the lamp cover 103 and the cover housing 101, and ensure the normal operation of the module.

[0062] The faceplate bracket 105 is securely mounted on the faceplate housing 101 using a specific fixing method. After installation, a specific area, namely the potting area, is formed between the faceplate bracket 105 and the side of the PCB board 104 away from the bottom surface of the accommodating cavity. The formation of this potting area is one of the key aspects of the waterproof design in this embodiment.

[0063] Within the potting area, adhesive is evenly poured in using a professional potting process. After the adhesive cures, a waterproof adhesive layer 106 is formed. The formation of the waterproof adhesive layer 106 achieves the encapsulation and sealing of the PCB board 104. It acts like a sturdy protective barrier, isolating the PCB board 104 from the external environment.

[0064] This embodiment cleverly incorporates a waterproof adhesive layer 106 within the press-fit faceplate assembly 1, and utilizes the glue-filling area formed between the faceplate bracket 105 and the PCB board 104 to inject adhesive and form the waterproof adhesive layer 106. This innovative design effectively solves the problem of insufficient waterproof performance faced by traditional coded switch modules. In traditional coded switch modules, due to the relatively simple connection and sealing methods between components, moisture can easily penetrate into the module's interior through gaps or weak points, damaging critical components such as the PCB board and leading to short circuits or other malfunctions. The waterproof adhesive layer 106 designed in this embodiment can tightly cover the surface of the PCB board 104, completely isolating moisture from direct contact with the PCB board 104, fundamentally preventing moisture from seeping into the module's interior, and greatly improving the module's reliability and stability in humid environments or applications requiring waterproof functionality.

[0065] Furthermore, the design of the lampshade 103 further enhances the module's sealing performance. Without the lampshade 103, there might have been slight gaps at the fixing points between the faceplate bracket 105 and the faceplate housing 101. However, with the lampshade 103 covering the PCB board 104, it ensures that moisture entering these gaps cannot further contact the PCB board 104. This all-around sealing design, combined with the waterproof adhesive layer 106, allows the module to adapt to various harsh environmental conditions, greatly expanding its application range. Whether in the field of outdoor equipment, such as outdoor lighting equipment and outdoor monitoring equipment, which often need to face various complex weather conditions, such as rain and fog; or in the field of kitchen appliances, where the kitchen environment is usually humid and contains a lot of water vapor and oil; or in the field of bathroom equipment, where high humidity and frequent water vapor contact place extremely high demands on the waterproof performance of the equipment, the waterproof coded switch module provided in this embodiment can operate stably with its excellent waterproof performance, demonstrating significant practicality and innovation, and providing strong support for the development and application of related electronic equipment.

[0066] Please refer to this again. Figure 2 In one embodiment of this invention, the connection structure between the faceplate housing 101 and the faceplate support 105 is meticulously and ingeniously designed. Specifically, a snap-fit ​​element 107 is precisely manufactured at the annular edge of the faceplate housing 101. The shape, size, and position of this snap-fit ​​element 107 have been carefully considered and designed to ensure its full performance in subsequent connection and fixation. Its design not only considers the fitting precision with the faceplate support 105 but also takes into account the stability and reliability of the overall structure, ensuring connection strength while also facilitating installation and disassembly.

[0067] Meanwhile, on the faceplate bracket 105, a corresponding latching part 108 is precisely provided to match the latching member 107 provided on the faceplate housing 101. The depth, width, and shape of the latching part 108 are all adapted to the latching member 107. Through this precise matching design, when the faceplate housing 101 and the faceplate bracket 105 are assembled, the latching member 107 can be smoothly inserted into the latching part 108, achieving a stable snap-fit ​​connection. This snap-fit ​​connection method eliminates the need for additional fasteners such as screws and nuts, greatly simplifying the assembly process, improving production efficiency, and reducing production costs. Moreover, this connection method also has good shock resistance, which can resist external vibrations and impacts to a certain extent, ensuring that the connection between the faceplate housing 101 and the faceplate bracket 105 remains stable under various working conditions, thereby ensuring the structural integrity and performance stability of the entire waterproof coded switch module.

[0068] Please refer to Figure 4-8In one embodiment of this invention, the waterproof coded switch module involved in this invention has a richer and more sophisticated structure. In addition to the core component 1 of the press cover mentioned above, it also includes three key components: the rotating component 2, the fixing component 3, and the base 4.

[0069] First, let's look at the fastener 3, which plays a crucial connecting and supporting role in this waterproof coded switch module. The fastener 3 achieves a stable assembly connection with the faceplate bracket 105 through a specific assembly process. During assembly, the precision requirements for the fit between the two are extremely high. Whether it's the dimensional matching of the connecting holes or the flatness and perpendicularity of the assembly surfaces, everything has undergone rigorous design and control. This high-precision assembly connection ensures that the fastener 3 and the faceplate bracket 105 form a stable and reliable overall structure, providing a solid foundation for the subsequent installation and operation of other components.

[0070] The rotating component 2, as the core component enabling the rotational operation function of this waterproof coded switch module, is ingeniously designed. The rotating component 2 is rotatably mounted between the faceplate bracket 105 and the fixing member 3, cleverly enclosing the faceplate bracket 105 within it. This design not only allows the rotating component 2 to rotate smoothly around a specific axis, realizing the rotational operation function of the coded switch, but also enhances the overall structural compactness and protective performance of the module to a certain extent by enclosing the faceplate bracket 105. The rotational movement of the rotating component 2 requires high flexibility and stability. It employs a special bearing structure or lubrication mechanism internally to ensure smooth and stable operation during frequent rotational operations, preventing jamming or loosening, thereby guaranteeing the accurate operation and long-term reliability of the coded switch.

[0071] The base 4 is also an indispensable and important component of this waterproof coded switch module. The base 4 and the fixing component 3 are connected through a specific assembly method, and the two have the ability to move relative to each other vertically. This relative vertical movement design gives the module a certain pressing function. At the same time, the connection structure between the base 4 and the fixing component 3 also needs to have a certain strength and stability to ensure that there will be no loosening or detachment during the relative vertical movement, thus guaranteeing the overall safety and reliability of the module.

[0072] In summary, the waterproof coded switch module in this embodiment cleverly combines the rotating component 2, the fixing component 3, and the base 4, and works in conjunction with the pressing faceplate component 1 to form a compact, fully functional, and reliable coded switch module that can meet various needs for coded switches in different application scenarios.

[0073] Please refer to this again. Figure 7-8In one embodiment of this invention, the rotating component 2 in the waterproof coded switch module has a finely structured composition, with each component working together to achieve a specific function. The rotating component 2 is mainly composed of several key components, including a knob housing 201, a rotating bracket 202, a spring 203, and a magnet 204.

[0074] The rotating bracket 202, serving as the core support and rotating carrier of the rotating assembly 2, is carefully positioned between the cover bracket 105 and the fixing member 3, enabling smooth rotation around a specific axis. During installation, the precision of the fit between the rotating bracket 202, the cover bracket 105, and the fixing member 3 is crucial. To ensure stable and flexible rotation, the contact surfaces between the rotating bracket 202 and the cover bracket 105 and the fixing member 3 have undergone fine machining to reduce frictional resistance. Furthermore, a suitable bearing structure or lubrication mechanism is employed to guarantee smooth and stable rotation, preventing issues such as jamming or abnormal noise, thus providing a reliable guarantee for the normal operation of the entire rotating assembly 2.

[0075] The knob housing 201 and the rotating bracket 202 are securely connected through a specific assembly process. During assembly, the connection points between the two are precisely designed and positioned to ensure that the knob housing 201 fits tightly against the rotating bracket 202, forming a unified structure. Simultaneously, the knob housing 201 cleverly encloses the faceplate bracket 105. This design not only enhances the overall structural compactness and aesthetics of the module but also provides a degree of protection, preventing external dust, moisture, and other impurities from entering the module and affecting its performance and lifespan. Furthermore, the appearance design of the knob housing 201 can be customized according to actual needs to meet the aesthetic requirements of different users.

[0076] The spring 203 is precisely positioned on the rotating bracket 202 and located between the rotating bracket 202 and the cover bracket 105. The spring 203 plays a crucial role in generating the tactile feedback of the rotational gears in this rotating assembly 2. When the user rotates the knob housing 201, causing the rotating bracket 202 to rotate, the spring 203 interacts with a specific structure on the cover bracket 105, generating a regular change in resistance. This allows the user to clearly feel different gear positions during rotation, achieving precise operational control. The material, shape, and elastic coefficient of the spring 203 have undergone rigorous testing and optimization to ensure it provides a stable and comfortable gear-shifting feel, meeting the user's requirements for the operational experience.

[0077] Several magnets 204 are evenly and rationally arranged on the rotating bracket 202. The arrangement and number of these magnets 204 have been precisely calculated and designed to ensure that they can generate accurate and stable sensing signals when interacting with the Hall chips 109 on the PCB board 104. Simultaneously, two Hall chips 109 are provided on the PCB board 104. When the rotating bracket 202 is rotated under user operation, it drives the magnets 204 on it to rotate accordingly. As the magnets 204 rotate, they respectively sense the two Hall chips 109. The Hall chips 109 can sense the changes in the magnetic field of the magnets 204 and convert them into corresponding electrical signals, i.e., sensing signals. These sensing signals are then transmitted to other control circuits of the module. After processing and analysis, accurate identification and control of the rotation operation of the coded switch are achieved. Through this sensing interaction between the magnets 204 and the Hall chips 109, this rotating component 2 achieves contactless signal transmission, with advantages such as fast response speed, high precision, and good reliability, effectively improving the overall performance and stability of the waterproof coded switch module.

[0078] In summary, the rotating component 2 in this embodiment achieves multiple functions such as rotation operation, gear position feedback, and signal sensing transmission through the precise cooperation and synergy between its various components, providing strong support for the normal operation and precise control of the waterproof coded switch module.

[0079] In one embodiment of this invention, the mating structure between the faceplate support 105 and the spring piece 203 is carefully and ingeniously designed. Specifically, the side of the faceplate support 105 facing the spring piece 203 is specially treated and configured as a wavy surface.

[0080] This wave-like surface design is not arbitrary, but rather the result of in-depth research and precise calculations. From a design principle perspective, the wave-like surface has a unique undulating shape, and the alternating arrangement of its crests and troughs perfectly matches the elastic deformation characteristics of the spring piece 203. When the rotating component 2 drives the spring piece 203 to rotate, the spring piece 203 will sequentially contact different parts of the wave-like surface. During the contact process, the spring piece 203 will undergo corresponding elastic deformation according to the undulations of the wave-like surface.

[0081] From a functional perspective, the interaction between the wave-shaped surface and the spring 203 produces a clear and distinct feel for the gear selection. When the spring 203 moves from one trough to one crest, it is compressed by the wave-shaped surface, generating a certain amount of resistance. The user can clearly feel this change in resistance, thus confirming that a gear has been selected. When the spring 203 moves from one crest to the next trough, the resistance suddenly decreases. This difference in resistance further enhances the tactile feedback of the gear selection, allowing the user to accurately and clearly perceive the rotation position and gear changes.

[0082] Furthermore, the wave-like surface design also provides a certain degree of fault tolerance and stability. Because the undulations of the wave-like surface are continuous and regular, even if the spring 203 experiences a slight positional deviation during rotation, the guiding and buffering effect of the wave-like surface ensures stable contact between the spring 203 and the cover bracket 105, preventing minor deviations from causing unclear shift feel or abnormal signal transmission. This design significantly improves the operational accuracy and reliability of the rotating component 2, ensuring that the waterproof coded switch module can operate stably and accurately in various operating environments, providing users with a superior operating experience.

[0083] In one embodiment of this invention, the functional design of the PCB board 104 has been further optimized and improved, and a surface-mount switch is specially provided on it. As a key electronic component, the surface-mount switch has many advantages such as small size, convenient installation, and stable performance, and is often used in electronic devices to realize signal triggering and control functions.

[0084] When the user applies downward pressure to the pressing faceplate assembly 1, the entire pressing action triggers a series of precise mechanical movements. The relative up-and-down movement between the fixing member 3 and the base 4 plays a crucial guiding role in the module structure, together forming a stable motion track. After being subjected to external force, the pressing faceplate assembly 1 will move smoothly downward along the direction defined by the fixing member 3 and the base 4, guided by them.

[0085] As the faceplate assembly 1 moves downward, the PCB board 104 also shifts. Since the surface mount switch is mounted on the PCB board 104, when the PCB board 104 moves to a specific position, the surface mount switch will contact the tip of the base 4.

[0086] The moment the surface mount switch contacts the tip of base 4, the circuit state changes, generating a pressing signal. This pressing signal is the key trigger signal for the module to perform its functions. It is transmitted to other control circuits in the module, and after processing and analysis, it further controls other components of the module to perform corresponding actions, such as turning the switch on and off or adjusting the device parameters.

[0087] This design, which uses the pressing faceplate assembly 1 to move under the guidance of the fixing member 3 and the base 4, causing the surface mount switch to contact the tip of the base 4 to generate a pressing signal, has the advantages of simple structure, reliable operation, and fast response speed. It ensures that when the user presses the pressing faceplate assembly 1, the module can quickly and accurately sense the operation intention and make a timely response, thereby improving the operation performance and user experience of the entire waterproof coded switch module.

[0088] Please refer to this again. Figure 4In one embodiment of this invention, the structural design of the base 4 fully considers the installation requirements of the module in practical applications. Specifically, mounting holes 5 are carefully provided on the base 4.

[0089] The location, size, and number of mounting holes 5 have been meticulously planned and designed. Positionally, the mounting holes 5, distributed on the base 4, ensure a stable and balanced position for the module when installed on the fixed panel, preventing wobbling or tilting during use due to improper installation. In terms of size, the diameter and depth of the mounting holes 5 are designed to match the specifications of common mounting bolts or screws, ensuring a tight fit with standard-sized fasteners and a reliable installation connection. Furthermore, the number of mounting holes 5 has been precisely calculated to ensure installation stability while avoiding excessive holes that would increase the processing difficulty and cost of the base 4.

[0090] In practical applications, mounting hole 5 plays a crucial role. By passing suitable bolts or screws through mounting hole 5 and screwing them into the corresponding threaded holes on the mounting panel, the waterproof coded switch module can be securely fixed to the mounting panel. This installation method is not only simple and convenient but also provides sufficient connection strength to ensure stable and reliable operation of the module in various working environments. Whether exposed to wind and rain in outdoor equipment, facing moisture corrosion in humid environments such as kitchens and bathrooms, or enduring vibration and impact in industrial equipment, the fixed installation achieved through mounting hole 5 ensures that the module will not loosen or fall off, thereby guaranteeing the normal operation and safety of the entire equipment system.

[0091] In summary, the mounting holes 5 on the base 4 provide a convenient and reliable solution for the installation of the waterproof coded switch module, enabling the module to be easily integrated into various devices and meet the installation requirements of different application scenarios.

[0092] Please refer to this again. Figure 4 In one embodiment of this example, the structural design of the base 4 exhibits high flexibility and practicality, and a limit latch 6 is specially provided.

[0093] The design of the limiting latch 6 is ingenious, with its shape, size, and layout on the base 4 carefully considered. In terms of shape, the limiting latch 6 has a specific protruding or recessed structure, which allows for precise matching with the corresponding latch structure on the fixing panel. Regarding dimensions, the dimensional tolerance of the limiting latch 6 is strictly controlled within a very small range to ensure a tight fit with the fixing panel's latch structure. It avoids installation difficulties or loose fit due to excessive size, and also avoids ineffective limiting and fixing due to insufficient size. Its placement on the base 4 is also carefully planned, typically located at the edge of the base 4 or at key stress points, so as to evenly distribute the external forces borne by the module after installation, ensuring the stability of the module installation.

[0094] During actual installation, the base 4 is fastened to the fixed panel via the limiting latch 6. When the module is brought close to the fixed panel, simply align the limiting latch 6 on the base 4 with the latching structure on the fixed panel, and then apply a certain amount of pressure. The limiting latch 6 will then engage with the latching structure, completing the fastening operation. This fastening method has the advantages of rapid installation and simple operation, requiring no additional tools and greatly improving installation efficiency. At the same time, the tight fit between the limiting latch 6 and the latching structure of the fixed panel provides a reliable fixing effect, preventing the module from loosening or falling off due to vibration, impact, or other factors during use, ensuring stable operation of the module in various complex environments.

[0095] It should be noted that in practical applications, the design of mounting hole 5 and limit latch 6 offers high flexibility. They can both be present on the base 4, or one can be chosen based on specific needs. When both are present, mounting hole 5 and limit latch 6 complement each other, providing double securing protection and further enhancing the stability and reliability of the module installation. For example, in applications with extremely high installation stability requirements, such as aerospace equipment and precision instruments, using both mounting hole 5 and limit latch 6 can effectively reduce the risk of the module loosening due to external factors. Conversely, when only a simple installation method is needed, or when space or cost constraints prevent installation, either mounting hole 5 or limit latch 6 can be used to meet different application requirements. This flexible design allows the waterproof coded switch module to better adapt to various installation scenarios, improving the module's versatility and practicality.
