Description

Technical Field

[0001] This invention is a metal microporous pressure-sensitive controller, belonging to the field of controllers. Background Technology

[0002] With the rapid development of smart home technology, home appliances are widely adopting touch-screen control panels. This design not only significantly improves user flexibility and interactive experience, but also endows products with stronger modern aesthetic value through a simple and smooth interface design. In terms of control methods, some high-end models have achieved deep integration with mobile terminals through wireless technologies such as Bluetooth and Wi-Fi, building an intelligent device ecosystem.

[0003] However, current wireless controllers still have room for improvement: most products use a fixed panel architecture, preventing users from customizing the interface according to their personal habits or aesthetic preferences; the rigid layout results in relatively fixed function keys, requiring novice users to learn the operation logic; some models have even completely eliminated physical buttons, which may affect operational accuracy in bright light environments or special usage scenarios. These factors collectively limit the user-friendliness and scenario adaptability of wireless control solutions, urgently requiring modular design and optimization of intelligent interaction algorithms to overcome existing limitations. Summary of the Invention

The outer ring of the support is provided with an inner seat for nested adjustment knob, and the surface of the inner seat is provided with a limiting hole that cooperates with the sliding post. The limiting hole includes a first diameter section and a second diameter section, the bottom of which is the first diameter section, and the diameter of the first diameter section is smaller than the diameter of the second diameter section. The limiting clip can rotate within the second diameter section under the action of external force.

[0009] Preferably, the adjustment knob has a bearing inside, which is nested on the outer edge of the inner seat. The inner edge of the adjustment knob has a toothed structure, which cooperates with the detection switch on the surface of the main board. When the adjustment knob is rotated, the toothed structure touches the detection switch, so that the detection switch is in an alternating on and off state.

[0010] Preferably, the extrusion part includes a base plate, sliding columns are arranged at equal intervals on the surface of the base plate, a reset spring is provided between adjacent sliding columns, and a limit stop is provided between the sliding columns and the torsion spring.

[0014] Preferably, the top of the ring body is provided with a receiving groove, through which the bottom plate located inside the receiving groove can be touched and pressed.

[0015] Preferably, the bottom surface of the ring body is provided with two or more magnetic suction parts.

[0016] The present invention provides a metal micro-hole pressure-sensitive controller, which has the following advantages: The improved device uses micro-holes on the surface of the plate to allow light to pass through, making the metal plate more textured and more indicative.

The sliding column and limit lock can also assist in pulling the board when it is separated, and the board is separated by external force to prevent it from falling off due to inertia. This allows for personalized settings and makes the controller more functional. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] Most existing products use a fixed panel architecture, which prevents users from customizing the interface according to their personal habits or aesthetic preferences. The rigid layout also results in relatively fixed function key positions, requiring novice users to invest additional learning time to master the operating logic. Therefore, to address these issues, this paper proposes the following technical solution:

[0041] Please see Figures 1 to 8This invention provides a technical solution for a metal microporous pressure-sensitive controller: its structure includes a control unit 1, which is installed in the middle of a base 3. A rotatable adjustment knob 2 is provided on the surface of the control unit 1. The control unit 1 includes a control panel 11 and a control plate 12, which are nested together with the control panel 11. The control panel 11 is also in clearance fit with the pressing part 32 of the base 3. The base 3 also includes a support 33 for supporting the control plate 12 and the adjustment knob 2. A bottom ring 31 for limiting the pressing part 32 is provided at the bottom of the support 33. A limit post 1 is provided on the bottom surface of the plate 111 of the control panel 11. 15 is movably connected to the sliding column 323 and the limiting card 324 of the extrusion part 32. The surface of the control plate 12 is provided with an auxiliary bracket 123. The center of the hole of the auxiliary bracket 123 coincides with the axis of the limiting column 115. The outer ring 331 of the support 33 is provided with an inner seat 333 of the nested adjustment knob 2. The surface of the inner seat 333 is provided with a limiting hole 335 that cooperates with the sliding column 323. The limiting hole 335 includes a first diameter section and a second diameter section. The bottom is the first diameter section, and the diameter of the first diameter section is smaller than the diameter of the second diameter section. The limiting card 324 can rotate under the action of external force within the second diameter section.

[0042] When in use, the main structure of this device includes a base formed by a control unit 1 and an adjustment knob 2, and an adjustment knob 2 nested on the outer surface of the control unit 1 for rotational adjustment. A control panel 11 is provided on the surface of the control unit 1. The control panel 11 can control the internal control board 12 and switch functions. A base 3 is provided at the bottom of the control board 12. The structure of the base 3 includes a support 33 for fixing the control board 12 and a pressing part 32 for easy disassembly of the control panel 11. A bottom ring 31 is provided at the bottom of the pressing part 32 for protection.

[0043] The specific structure of the control panel 11 includes a panel 111, which serves as the panel. A pressing part 116 is provided on the surface for pressing and positioning prompts. The panel 111 is made of metal, and micro-holes are provided at the pressing part 116 to allow light to pass through. A deformation groove 112 is provided in the area corresponding to the installation position of the pressing part 116. The deformation groove 112 reduces the thickness of the panel 111, and a sensor 113 is provided at the corresponding position of the deformation groove 112 to detect the deformation pattern. Specifically, the sensor 113 is a strain gauge, such as a resistive strain gauge. When the pressing part 116 area is pressed, a small deformation occurs, which changes the resistance value of the sensor 113. Data processing is performed at the indicator light group 114, and the change in the pressing value is identified as being in a triggered state.

[0044] Sensor 113 is connected to control board 12 via indicator light group 114. A terminal is located in the middle of indicator light group 114, and the terminal is nested with the second interface 124 on the surface of main board 121. Signal processing is performed by main board 121. A buffer pad 122 is also provided on the surface of main board 121. The backlight is enhanced by the micro-holes in the pressing part 116 for a more aesthetically pleasing design. This device uses the pressing part 116, deformation groove 112, and sensor 113 in conjunction with each other, triggering the device through a metal pressing method. This not only solves the problem of accidental touches when the capacitive screen is wet but also improves overall integrity. The metal material has a better texture, and the micro-holes ensure that the pressing part 116 still has a backlight indicator, making it more convenient to use. The detection switch 125 is set on the surface of the main board 121 and rotates and adjusts in conjunction with the adjustment knob 2. The two detection switches 125 can improve the recognition accuracy. Compared with the encoder's rotation mechanism, the structure of this application, which selects the adjustment method through the detection switch 125 and the adjustment knob 2, is more compact. The adjustment knob 2 is nested in the inner seat 333 of the support 33 through a bearing, making the rotation smoother and the feel better.

[0045] Traditional controller panels and motherboards are integrated into one unit, and the buttons usually cannot be customized, meaning that special treatments such as changing patterns can only be done by purchasing different models of controllers for corresponding operations, which is quite troublesome in terms of use and compatibility.

[0046] This controller has been optimized, and the control panel 11 is designed to be detachable. This means that different styles of panels can be replaced by disassembling the control panel 11. Different panels can have different patterns, and different control modes can be identified by the chip inside the indicator light group 114. The more intuitive guidance through the patterns can improve the operability and make it more intuitive.

[0047] However, replacing it by directly prying it off by hand can easily cause the board 111 to fall off, because there is resistance when the indicator light group 114 and the second interface 124 on the surface of the motherboard 121 are engaged, and it is easy to fall off due to inertia when the two are separated.

[0048] The optimization of this device for easy disassembly is as follows:

[0049] A limiting post 115 is provided at the bottom of the plate 111 to engage with the pressing part 32. The plate 111 can be limited by the pressing part 32, and the display light group 114 can be disengaged by the pushing of the pressing part 32, and the plate 111 will not fall off due to inertia.

[0050] The implementation method is as follows: a groove is provided at the bottom of the limiting post 115, and the groove cooperates with the limiting card 324 at the top of the sliding post 323 on the surface of the extrusion part 32. In order to better maintain the posture of the limiting card 324 and engage with the limiting post 115, a torsion spring 325 is provided at the pivot of the limiting card 324. Under the elastic force of the torsion spring 325, the limiting card 324 can be engaged with the limiting post 115.

[0051] A reset spring 322 is installed between the base plate 321 and the gap of the limiting card 324. The reset spring 322 is an elastic plate that can create a gap between the base plate 321 and the groove at the bottom of the outer ring 331. This allows the reset spring 322 to drive the limiting card 324 to slide inside the limiting hole 335 for locking. The limiting hole 335 has a variable diameter structure. The first diameter section slides with the surface of the sliding column 323, and the diameter of the second diameter section is larger than the first diameter. When the limiting card 324 is in the second diameter section, it can move freely. When it is in the first diameter section, it can be locked and limited. The corresponding action with the base plate 321 is as follows: when in a stationary state, the reset spring 322 pushes the base plate 321 away from the bottom surface of the outer ring 331, so that the sliding column 323 and the limiting card 324 are inside the first diameter section, and the limiting card 324 and the limiting column 115 are locked and cannot be separated.

[0052] In the separated state, pressing the base plate 321 makes the reset spring 322 flat, and the limit card 324 is located in the second diameter section. At this time, the plate 111 is pushed out of the display light group 114 and can provide auxiliary limit for the plate 111. When the finger is pried out, it is disengaged and stable separation is achieved.

[0053] After replacement, in order to better position the limiting post 115, an auxiliary bracket 123 is set on the surface of the main board 121. The auxiliary bracket 123 is located at the position corresponding to the limiting hole 335. The limiting post 115 can be pre-positioned by inserting into the auxiliary bracket 123, which makes installation more convenient and allows the second interface 124 to be fastened more quickly.

[0054] To prevent accidental contact with the base plate 321 during daily use, a slot is provided at the bottom of the outer ring 331 to accommodate the pressing part 32, and the bottom ring 31 provides a limiting position. The bottom ring 31 includes a ring body 311, which engages with the inner thread of the outer ring 331 through a limiting thread 314 on its outer surface. A magnetic part 312 is provided at the bottom of the ring body 311, which can be easily attracted to a metal surface for easier storage. A central groove 313 is provided in the middle of the ring body 311, through which the base plate 321 installed between the receiving groove 315 and the outer ring 331 can be touched, making it more convenient to use.

[0055] The support 33 includes an outer ring 331, on the surface of which a power supply battery 334 is disposed, and a charging sub-plate 332 that cooperates with the battery 334. The battery 334 can be charged through the charging sub-plate 332.

[0056] By using the micro-holes in the deformation groove 112 in conjunction with the display lamp group 114, not only can more patterns be displayed, but the sensor 113, which surrounds the deformation groove 112, detects deformation and generates electrical signals, improving the sensitivity of touch control and making the structure more compact in use.

[0057] The improved device uses a micro-perforated pressing part 116 on the surface of the plate 111 to transmit light, making the metal plate 111 more textured and more indicative. The pressure is detected by the sensor 113 located at the corresponding position of the pressing part 116. The pressure-sensitive touch control method is dustproof and waterproof, and can be adapted to various usage scenarios.

[0058] The base plate 321 controls the sliding column 323 and the limit card 324, enabling them to better limit and support the limit column 115 at the bottom of the board 111. This not only locks the limit column 115, but also releases the display light group 114 in the middle of the board 111 when the board is separated by pressing the base plate 321, preventing damage to the terminals. Furthermore, the sliding column 323 and the limit card 324 provide auxiliary pulling for the board 111 during separation, preventing the board 111 from falling off due to inertia by using external force to facilitate personalized settings and enrich the functions of the controller.

[0059] The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0060] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
