Description

Technical Field

[0001] This utility model relates to the field of knob technology, specifically to an intelligent knob for interactive devices. Background Technology

[0002] A knob is a manually operated component controlled by hand. Depending on functional requirements, it can be rotated continuously or multiple times, with a rotation angle reaching 360°. Knobs can be categorized into various types based on function and structure, such as mechanical knobs, electronic knobs, and digital knobs. Their main functions include controlling circuits and motors, adjusting parameters, and selecting functions. Knobs are commonly used in televisions, stereos, washing machines, air conditioners, and other equipment to adjust parameters such as volume, brightness, and mode.

[0003] Traditional rotary switches require the rotating shaft to pass through the product casing and be directly exposed on the product's outer surface for user operation. This necessitates openings in the product's outer surface, affecting its appearance. For products with special requirements, waterproofing and oil resistance must be considered after openings are made. In addition, existing knobs also suffer from excessive rotational resistance and the ability to scratch the product casing. Utility Model Content

[0014] Beneficial effects

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This invention boasts high precision: By employing a magnetic encoding chip to sense and locate changes in the magnetic field generated by the annular roller magnet, it achieves high-precision knob position detection, ensuring accurate response to operating commands in various application scenarios and effectively avoiding positioning inaccuracies caused by mechanical structure errors. 2. Low maintenance requirements: Its simple structure and rational internal design reduce the use of complex mechanical parts, lowering costs and significantly reducing the frequency of maintenance and replacement due to component wear and aging, saving users considerable maintenance time and costs.

[0017] 2. This utility model also boasts excellent sealing and reliability: by fixing the internal support of the knob to the base shell to form an effective seal, it effectively prevents external impurities such as water and dust from corroding key components such as the magnetic encoding chip. This ensures that the knob can still operate stably and reliably under harsh environmental conditions, further enhancing the overall durability and adaptability of the product, making it widely applicable to various devices with different environmental requirements. Compact design advantages: The absence of a separately protruding rotating shaft makes the overall appearance of the knob simpler, more aesthetically pleasing, and more compact, saving space in the device layout and facilitating miniaturization and integration. It is particularly suitable for precision instruments or portable devices with high space requirements. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a technical solution: an intelligent knob for an interactive device. Please refer to [link / reference]. Figure 1-7 The device includes a knob housing 1, a base housing 10 at the lower end of the knob housing 1, an internal knob support 5 between the knob housing 1 and the base housing 10, a PCB circuit board 8 between the internal knob support 5 and the base housing 10, a magnetic encoding chip 9 in the middle of the PCB circuit board 8, and a USB connection port 7 at the edge of the PCB circuit board 8. The internal knob support 5, the PCB circuit board 8, and the base housing 10 are fixedly connected by screws 6. An annular roller magnet 2 is installed inside the knob housing 1. An external annular buckle 4 is fitted on the internal knob support 5. An internal annular buckle 3 is fitted on the lower end of the knob housing 1. The lower end of the knob housing 1 passes through the internal knob support 5.

[0028] In this embodiment, a notch is provided on the side wall of the base shell 10, and the width of the notch is the same as that of the USB connection port 7.

[0029] Figure 2 As shown, in this embodiment, the surface of the knob housing 1 is provided with a groove, and the user can put their finger into the groove to facilitate the rotation of the knob housing 1;

[0030] In this embodiment, the magnetic coding chip 9 is model MT6701; the screw 6 has a diameter of 2.5mm.

[0031] The working process of this device is as follows: The knob of this utility model is fixedly connected to the base shell 10, the PCB circuit board 8 and the knob internal support 5 by screws 6, and a magnetic encoding chip 9 is provided in the middle of the PCB circuit board 8. An annular roller magnet 2 is fixedly provided inside the knob shell 1. The magnetic encoding chip 9 uses the magnetic field generated by the annular roller magnet 2 to determine the position.

[0032] When the user applies rotational force to the knob housing 1, the annular roller magnet 2 rotates synchronously with the knob housing 1 because the knob housing 1 is directly connected to the annular roller magnet 2. During rotation, the magnetic field distribution around the annular roller magnet 2 changes dynamically. The magnetic encoding chip 9 is positioned to sense changes in the magnetic field of the annular roller magnet 2. Through its built-in precision sensors and circuitry, it monitors changes in parameters such as the strength and direction of the magnetic field in real time. Based on a pre-set algorithm that correlates magnetic field changes with the knob position, the magnetic encoding chip 9 converts the detected magnetic field changes into corresponding electrical signals and further processes them into digital signals that can be recognized by the control system in the interactive device, thereby determining the current rotational position of the intelligent knob. The control system in the interactive device executes corresponding functional operations based on the received knob position signal, such as adjusting the volume, switching channels, and adjusting parameter settings, thus achieving the purpose of controlling and adjusting device functions through knob operation. This non-contact design based on magnetic field induction avoids the performance degradation and shortened lifespan problems caused by friction and wear in traditional mechanical structures, ensuring the stability and durability of knob operation.
