Description

Technical Field

[0001] The present invention belongs to the technical field of smart homes, and in particular relates to a knob smart control panel. Background Art

[0002] Knobs are widely used in various technical fields due to their unique operating characteristics. However, most buttons only have switching functions or require other buttons to achieve confirmation functions. They are extremely inconvenient to operate and have a simple feel and feedback form.

[0003] With the development of technological applications, knobs have mainly developed into the following four forms:

[0004] Form 1: A hollow encoder is used as a rotary structure, and a damping mechanism can be provided. However, the overall structure is bulky and requires additional buttons to create a confirmation function. The structure is complex and the damping form is single.

[0005] Form 2: The entire knob module is supported by four springs, and a button is set in the middle of the rotary module for confirmation. This type of structure requires the knob module to be made very large, and the feel of pressing to confirm is extremely poor.

[0006] Form 3: A knob encoder is used as a rotary structure and combined with its own spring for function confirmation. However, this type of button with a knob function is mostly suitable for single-function buttons. If a screen needs to be added to the knob as an interactive interface, it will be limited by the small size and low strength of the device itself.

[0007] Form 4: A knob structure composed of bearings, optical tracking sensors, and linear motors. This type of structure only has a rotation switching function and a certain feedback vibration, but requires an additional button for confirmation, and the feel is monotonous.

[0008] The above four categories have the following drawbacks: Current knob-type buttons on the market are bulky, complex, have a poor and monotonous rotational feel, and often lack physical feedback. For example, on a smart home control panel, a knob might be defined as controlling functions such as scenes, lighting, dimming, curtains, air conditioning, floor heating, and fresh air. Traditional knob panels are largely incapable of meeting these requirements. With the introduction of screens, knobs can serve as human-computer interfaces, but due to product size limitations, knob screens are typically small and inconvenient for touchscreen applications. Therefore, a knob with a confirmation function is needed, allowing users to select and switch functions by rotating and confirm by pressing. Especially for smart control panels that require a European-standard base box (which is very small), the above four types of knob structures generally fail to meet these requirements. Furthermore, due to their chosen design, current knob panels are often very thick, typically around 12mm or even thicker. Panels of this thickness appear unwieldy and lack refinement, regardless of design or design changes. Summary of the Invention
