[0018] In order to describe the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings.

[0019] In the following description, specific examples are given in order to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. It should be understood that the specific embodiments are only used to explain the present invention, and are not used to limit the present invention.

[0020] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or combinations thereof.

[0021] Please refer to Figures 1-7 , a non-contact sensing knob controller structure of the present invention includes a knob base 1, a rotation detection component 3 and a main control board 5. A rotatable rotary knob 2 is provided on the knob base 1. The rotary knob 2 and the knob base 1 enclose a receiving space. A battery 6 is provided on the knob base 1. The rotation detection component 3 is arranged in the receiving space to detect the rotary knob 2 through the rotation detection component 3. The main control board 5 is arranged on the rotation detection component 3 and is electrically connected to the rotation detection component 3, the battery 6 and the power supply board for receiving the information detected by the rotation detection component 3. It further includes a wireless communication chip, and the main control board 5 is electrically connected to the wireless communication chip. By adding the battery 6, the present invention realizes the portable carrying of the knob, improves the convenience and practicability of the product. The power supply board can convert the output voltage of the battery 6 to ensure the safety of the product. At the same time, the rotation of the rotary knob 2 is accurately detected by the rotation detection component 3, and the wireless communication chip enables the knob to interact with electronic products in wireless communication modes such as Bluetooth and WIFI. The main application scenarios include smart home control such as lights, curtains, speakers, power amplifiers, etc.; car infotainment system control screen control, such as controlling the multimedia functions of the car infotainment system control screen through this product, such as music, radio, APP switching, air conditioning, etc.; home appliance control: function switching and function setting of various functional home appliances such as ovens, coffee makers, water dispensers, etc. As long as the electronic product has a wireless connection function, it can be wirelessly connected to this product and realize knob control.

[0022] The working principle of the present invention is: When rotating the rotary knob 2, the wave structure 220 on the inner shell of the rotary knob 2 passes by the infrared sensor 32 on the fixed seat 31. The grating 4 below the concave portion 2221 of the wave structure 220 will block the detection of the infrared sensor 32. Therefore, whenever the concave portion 2221 of the wave structure 220 passes by the infrared sensor 32, the infrared signal emitted by the infrared sensor 32 is blocked by the grating 4 and no reflected signal is received, which is equivalent to rotating a corresponding angle. When the convex portion 2220 passes by the infrared sensor 32, the infrared sensor 32 receives the reflected signal of the grating 4, which is equivalent to rotating an angle. Through such regular alternating detection, the main control board 5 can determine the rotation angle and number of turns of the rotary knob 2 based on the signal detection duration and number of times of the infrared sensor 32. And in order to determine whether the rotation direction of the rotary knob 2 is clockwise or counterclockwise, the number of receiving ends of the infrared sensor 32 is two and they are arranged adjacent to each other. The rotation direction is determined according to the sequence of signal reception by the two receiving ends of the infrared sensor 32; the telescopic spring 82 and the top bead 83 provided on the partition bracket 8 can form a linkage cooperation with the convex portion 2220 and the concave portion 2221 of the wave structure 220 when the rotary knob 2 rotates; when the rotary knob 2 rotates, the top bead 83 continuously collides with the convex portion 2220, generating a friction click sound. When the rotation stops, the top bead 83 cooperates with the concave portion 2221, and the telescopic spring 82 fully ejects the top bead 83, so that the top bead 83 is stuck in the concave portion 2221 to remain fixed; a control panel 13 is provided on the partition bracket 8. Function signals are input to the main control board 5 through the control panel 13, and the main control board 5 then outputs function signals to the electronic product with wireless function through the wireless communication chip. At the same time, the rotation detection signal generated by the infrared sensor 32 also passes through the main control board 5 to be converted into an output value and output to the electronic product to adjust the electronic product.

[0023] In this embodiment, a battery compartment 7 is provided on the knob base 1. The two end faces of the inner ring of the bearing 21 are respectively abutted against the fixed seat 31 and the battery compartment 7. A connecting slot hole 71 and a connecting through hole 72 are formed on the battery compartment 7. A connecting post 311 that fits into the connecting slot hole 71 is formed on one surface of the fixed seat 31 relative to the rotating base; a threaded post 84 is provided on the separating bracket 8, and an external bolt passes through the connecting through hole 72 and is threadedly connected to the threaded post 84. The fixed seat 31 and the battery compartment 7 squeeze the inner ring of the bearing 21 to fix the bearing 21; by respectively squeezing the inner ring of the bearing 21 with the fixed seat 31 and the rotating base, the inner ring of the bearing 21 is kept fixed relative to the outer ring, thereby realizing the fixation of the bearing 21, and by threading the external bolt through the connecting through hole 72 and the threaded post 84, the fixation of the bearing 21 is further strengthened; the connecting through hole 72 and the connecting post 311 are fitted with each other, which can further ensure that the connection between the fixed seat 31 and the base is stable, making the structure of the entire knob more stable. Even if problems such as being smashed, dropped, etc. occur, the structure of the knob will not become loose, ensuring the quality.

[0024] In this embodiment, the rotary knob 2 includes a bearing 21, a rotating inner shell 22, and a rotating outer shell 23 that are sequentially sleeved. The rotation detection assembly 3 includes a fixed seat 31 and an infrared sensor 32. The fixed seat 31 is fitted with the knob base 1. The rotating inner shell 22 is sleeved on the outer ring of the bearing 21. At least one grating 4 is circumferentially provided on the wall surface of the rotating inner shell 22 relative to the bearing 21. The infrared sensor 32 is opposite to any one of the gratings 4. When the rotary knob 2 rotates, the magnitude of the user's adjustment amplitude can be judged according to the signal rate fed back by the infrared sensor 32, and then the parameter adjustment amplitude of the electronic product can be controlled. For example, when the detection rate of the infrared sensor 32 signal per unit time is fast, the adjustment amplitude becomes larger, and when the detection rate per unit time is slow, the adjustment amplitude becomes smaller. Specifically, a reference rate can be set to distinguish the fast and slow boundaries to identify the user's adjustment needs. And since there is no physical frictional contact between the infrared sensor 32 and the grating 4, the overall service life of the knob is further improved.

[0025] In this embodiment, the number of receiving ends of the infrared sensor 32 is two, and the number of transmitting ends of the infrared sensor 32 is one. The rotation direction of the rotating inner shell 22 is judged according to the signal receiving order of the two receiving ends of the infrared sensor 32; since when the rotary knob 2 is stationary, the top bead 83 on the separating bracket 8 must be in one of the recesses 2221, when the rotary knob 2 is rotated, the receiving end of the infrared sensor emits a signal, and the grating will pass through the two receiving ends of the infrared sensor 32 successively. The rotation direction is judged according to the receiving end of the infrared sensor 32 that first recognizes the signal. If the left receiving end first recognizes the reflected signal and the right receiving end subsequently recognizes the reflected signal, the rotation direction can be determined to be from left to right, and vice versa. At the same time.

[0026] In this embodiment, the cylindrical surface of the partition bracket 8 is provided with spring holes 81 opposite to the wave structure 220. An expansion spring 82 and a top bead 83 are arranged in the spring holes 81. The two ends of the expansion spring 82 are fixedly connected to the end face of the spring hole 81 and the top bead 83 respectively, and the top bead 83 partially protrudes from the spring hole 81. When the rotary knob 2 rotates rapidly, due to the elastic force of the expansion spring 82 and the alternation of the convex portions 2220 and concave portions 2221 of the wave structure 220, the top bead 83 on the partition bracket 8 continuously collides with the convex portions 2220 and is squeezed back into the spring hole 81, and then pops out of the hole again due to the elastic force of the expansion spring 82, making a clicking sound through continuous rotation, adding a certain amount of fun and stress relief experience to the rotary switch; and the expansion spring 82 also provides a certain feel for the rotation. The resistance generated by it makes the user not rotate too smoothly when rotating. The user needs to overcome the elastic force of the expansion spring 82 to push the top bead 83 back into the spring hole 81, avoiding the problem of excessive amplitude fluctuation when the user adjusts the parameters, and different rotation feels can also be obtained by adjusting the size of the top bead 83 and the length and elastic force of the expansion spring 82; further, the concave portions 2221 are adapted to the number of the gratings 4, and the position of any grating 4 corresponds to any concave portion 2221. When any concave portion 2221 cooperates with the top bead 83, the grating 4 is also opposite to the infrared sensor 32. The signal of the infrared sensor 32 will be blocked once every time it passes through a concave portion 2221. At this time, the rotation angle of the rotary knob can be accurately calculated. And when the rotary knob stops rotating, the expansion spring 82 presses against the top bead 83 for a long time, and the infrared signal of the infrared sensor 32 will always be blocked by the grating 4. When the infrared sensor 32 is aligned with the concave portion 2221, the grating 4 corresponding to the position of the concave portion 2221 blocks the reflection of the infrared signal. When it comes to the convex portion 2220, the infrared sensor 32 receives the infrared signal again, thereby realizing the determination of angle and rotation detection.

[0027] In this embodiment, a control panel 13 is provided above the partition bracket 8. The control panel 13 is fixedly connected to the partition bracket 8 and electrically connected to the main control board 5. The control panel 13 can be a mechanical push panel, a liquid crystal display panel or a capacitive touch panel. According to the usage scenarios and requirements of different users, the type of the control panel 13 can be changed accordingly. The main function of the control panel 13 is to be able to select different functions of the electronic product. When the control panel 13 is a mechanical push panel, functional patterns can be engraved on the panel by laser to present different function buttons. Among them, the liquid crystal display panel and the capacitive touch panel have more functions than the mechanical push panel. The liquid crystal display panel and the capacitive touch panel can be displays such as LED, LCD, OLED, TFT, etc., and are mainly used for designing the function interface on the panel for scenarios such as car navigation systems or home scenes, improving the cost performance and practicability of the knob. When the control panel 13 is a capacitive touch panel, an empty cavity is formed between the control panel 13 and the fixed seat 31. Based on the finger touching the panel to change the capacitance on the panel to confirm the touch signal, touchless touch is realized. When the control panel 13 is a mechanical push panel, a backlight and induction contacts corresponding to the panel buttons are provided on the control panel 13. When the button on the panel is pressed, the corresponding induction contact receives the pressing signal, and the backlight is synchronously lit to form a feedback. Function signals can be input to the main control board 5 through the control panel 13, and the main control board 5 outputs function signals to external electronic products with wireless functions through the wireless communication chip to realize the control function.

[0028] In this embodiment, a power switch 11 and a charging interface 10 are provided on the knob base 1. The power switch 11 is electrically connected to the main control board, and the charging interface 10 is electrically connected to the power board 12. Through the cooperation of the battery 6 and the charging interface 10, the knob can be carried portably. The charging interface 10 is powered by an external power supply and inputs power to the power board and then to the battery 6. The charging interface 10 includes a Type-C interface and a magnetic contact interface, and the charging interface 10 can also be expanded into a wireless charging coil to realize wireless charging of the knob. The power switch 11 is to prevent the infrared sensor 32 and the main control board 5 from continuously outputting signals when the user plays with the knob without using the knob switch, resulting in waste of battery 6 power.

[0029] In this embodiment, the bottom of the knob base 1 is a magnetic adsorption surface, and the knob with magnetic adsorption function can be placed arbitrarily on the surfaces of metal objects, walls, and boards, providing a very convenient placement function and improving the practicability of the product.

[0030] The advantages of the present invention are as follows: The present invention enables the knob to be portably carried by adding a battery, which improves the upper limit of product use. Moreover, the magnetic adsorption part at the bottom of the knob base enables the knob to be adsorbed on any metal surface, further enhancing the practicality and convenience of the product. Based on the cooperation between the infrared sensor and the grating, the detection of the rotation angle and number of turns of the knob switch is achieved. In terms of cost control, a lower price is also obtained compared with traditional position sensors. Additionally, the adjustment amplitude of the knob can be controlled according to the detection rate of the infrared sensor, and the parameters of electronic products can be adjusted with high precision and quickly.

[0031] The above-disclosed are only several specific embodiments of the present invention. However, the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
