[0002] An illuminated knob is a knob device with a light-emitting function. From the appearance, it usually has a unique design and may have exquisite textures such as CD grain to enhance its aesthetics and texture. In terms of function, the illuminated knob is powered by a built-in battery or an external power source. It contains a light-emitting element, such as an LED. When powered, the light-emitting element emits light, making the knob clearly visible even in dark or low-light environments.

[0003] Illuminated knobs can be used in various devices, such as audio equipment, car dashboards, electronic instruments, etc. They not only play the role of adjustment and control, but also add a sense of technology and decoration to the equipment. Its lighting effect can be different modes such as constant light, flashing, and color change. Some illuminated knobs can also be controlled by sensing, touch, etc., to achieve a more intelligent operation experience.

[0004] However, when using the existing technology, an external power supply is usually required to control the brightness of the knob by controlling the power supply. However, in actual application, the external power supply has certain safety risks. For example, damaged wires may cause leakage, short circuit and other dangerous situations. Especially in some humid or dusty environments, the safety hazards are more prominent. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 4 As shown, the CD-patterned battery-powered luminous knob includes a CD-patterned top cover 1, a non-slip rubber ring 2 is fixedly connected to the bottom of the CD-patterned top cover 1, a knob 3 is fixedly connected to the bottom of the non-slip rubber ring 2, a PCB luminous board 4 is fixedly connected inside the knob 3, a patch-type Hall sensor 7 is mounted on the PCB luminous board 4, a base 5 is rotatably connected to the side of the knob 3 away from the CD-patterned top cover 1, a magnet 9 is fixedly connected to the side of the base 5 close to the CD-patterned top cover 1, a threaded barrel 12 is fixedly connected to the side of the knob 3 close to the base 5, and a control circuit is provided on the PCB luminous board 4; wherein the central axes of the CD-patterned top cover 1, the non-slip rubber ring 2, the knob 3, the PCB luminous board 4 and the base 5 all coincide.

[0022] In the present invention, in terms of safety, the power supply is installed in the mounting column 8, and the external power supply method is completely abandoned, thereby effectively avoiding dangerous situations such as leakage and short circuit caused by damaged wires, especially in humid or dusty environments. The built-in power supply does not require an external power supply and cumbersome line connection, and is more convenient to use. It is not restricted by the position of the external power supply and can be flexibly used in more occasions. The combination of the chip hall sensor 7 and the magnet 9 is used to realize intelligent control of the light brightness. Even if the power supply is set inside the knob 3, when the magnet 9 approaches the chip hall sensor 7, the power supply can be automatically cut off to achieve power off. By turning the knob 3 to adjust the position of the chip hall sensor 7 and the magnet 9, the on and off state of the PCB light-emitting board 4 can be conveniently controlled. Through the built-in power supply and unique brightness control method, the safety risk problem of the external power supply in the prior art is successfully solved, and the problem of the prior art power supply being set outside the knob 3 and having poor safety in the background technology is solved.

[0023] Further, such as Figures 1 to 4As shown, a mounting cavity is recessed into the side of the base 5 near the knob 3. A baffle is positioned within the cavity, forming a channel between the outer side of the baffle and the inner wall of the cavity. The baffle has an opening, and the bottom end of the knob 3 is positioned within the channel. A magnet 9 is fixedly mounted at the opening of the baffle. The channel is an annular groove that allows the knob 3 to rotate. When the knob 3 rotates, the PCB light-emitting board 4, which is fixedly connected to the knob 3, also rotates. The surface-mounted Hall effect sensor 7 mounted on the PCB light-emitting board 4 passes over the magnet 9, illuminating the PCB light-emitting board 4.

[0024] Specifically, before use, first install the power supply in the mounting column 8, then screw it to the bottom of the rotating shaft 11, connect the power supply to the PCB light-emitting board 4, and glue the patch type Hall sensor 7 to the PCB light-emitting board 4. The Hall sensor usually has four pins, namely the power supply positive VCC, the power supply negative GND, the output OUT and the ground pin. Connect the VCC pin to the positive pole of the power supply of the PCB light-emitting board 4, the GND pin to the negative pole of the power supply, and the OUT pin to the circuit part that controls the PCB light-emitting board 4 to be turned off. When in use, the CD threaded cover can be rotated by external force to make the PCB emit light. The chip-type Hall sensor 7 on the board 4 is close to the magnet 9. When the magnet 9 approaches the Hall sensor, the magnetic field strength changes. The Hall sensor detects this change and outputs another electrical signal based on the strength and direction of the magnetic field. The PCB light-emitting board 4 receives this signal, which is connected to the circuit part that controls the power on and off. When the chip-type Hall sensor 7 outputs a power-off signal, the control circuit cuts off the power supply, thereby powering off the device. The control circuit on the PCB light-emitting board 4 is used to receive the output signal of the chip-type Hall sensor 7 and control the power on and off of the PCB light-emitting board 4 based on this signal.

[0025] A rotating shaft 11 is fixedly connected to one side of the knob 3 near the base 5. The base 5 is rotatably connected to the rotating shaft 11. By setting the rotating shaft 11 at the center of the knob 3, when the knob 3 is turned, the PCB light-emitting board 4 and the chip-type Hall sensor 7 can be driven to rotate together, thereby achieving adjustment of the position of the chip-type Hall sensor 7 and the magnet 9.

[0026] A mounting tube 10 and a threaded tube 12 are fixedly connected to one side of the knob 3 near the base 5. Both the mounting tube 10 and the threaded tube 12 are slidably connected to the PCB light-emitting board 4. The mounting tube 10 and the threaded tube 12 can be used to connect screws of different specifications, making the connection between the PCB light-emitting board 4 and the knob 3 tighter.

[0027] An indicator 6 is provided on the CD-patterned top cover 1. By providing the indicator 6 on the CD-patterned top cover 1, when in use, it serves as a zero point position, making it convenient for staff to quickly identify the specific position of the patch type Hall sensor 7.

[0028] The above scheme still has the problem of how to prevent the power supply from Figures 1 to 4 As shown, a mounting column 8 is fixedly connected to the bottom of the rotating shaft 11. A threaded groove is provided in the mounting column 8. The mounting column 8 is threadedly connected to the rotating shaft 11. By providing the mounting column 8, the mounting column 8 can be used to support the power supply to ensure that the power supply is placed in the rotating shaft 11.

[0029] Furthermore, a through hole is provided in the center of the base 5 , and mounting holes are provided on both sides of the through hole for connection and fixation.

[0030] Furthermore, the edge of the CD-patterned top cover 1 is provided with anti-slip grooves, and the outer side of the anti-slip rubber ring 2 includes a plurality of raised circular anti-slip elements, thereby providing additional gripping force and comfort of use.

[0031] Working principle: Figure 1 - Figure 4 As shown, before use, install the power supply in the mounting column 8, screw it to the bottom of the rotating shaft 11, and connect the power supply to the PCB light-emitting board 4;

[0032] When an external force rotates the CD-patterned top cover 1, the knob 3, the PCB light-emitting board 4, and the chip Hall sensor 7 are driven to rotate together. The position of the chip Hall sensor 7 (model: HT3144) and the magnet 9 is adjusted by the rotating shaft 11. Under normal circumstances, when there is no magnet 9 close to the Hall sensor, the light-emitting knob 3 is in the energized and luminous state. When a magnet 9 approaches the chip Hall sensor 7, the magnetic field strength changes. The chip Hall sensor 7 detects this change and outputs another electrical signal based on the strength and direction of the magnetic field. The PCB light-emitting board 4 receives this signal, which is connected to the circuit part that controls the power on and off. When the chip Hall sensor 7 outputs a power-off signal, the control circuit will cut off the power supply, thereby powering off the device. The PCB light-emitting board 4 can be controlled by rotating the knob 3.

[0033] The power supply is installed in the mounting column 8, and the power supply is sealed by twisting the rotating shaft 11. Then, through the application of the patch type Hall sensor 7 and the magnet 9, the light brightness can be controlled even if the power supply is set inside the knob 3.

[0034] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
