Function control module

Abstract

A functional control module includes a keyboard, a knob, a first magnetic element, at least one sensor, and a controller. The knob is detachably and rotatably located on the keyboard. The first magnetic element is disposed on the knob. The at least one sensor is electrically connected to the keyboard. The controller is electrically connected to the keyboard and the at least one sensor. The at least one sensor is used to sense a change in a first magnetic field corresponding to a change in the distance between the first magnetic element and the at least one sensor, so that the controller determines the rotation state of the knob based on the change in the first magnetic field. This improves the sensitivity of the knob and other functional control components during operation, thereby enabling precise functional operation.

Claims

1. A functional control module, comprising: a keyboard; a knob detachably and rotatably located on the keyboard; a first magnetic element disposed on the knob; at least one sensor electrically connected to the keyboard; and a controller electrically connected to the keyboard and the at least one sensor; wherein, The at least one sensor is used to sense a change in a first magnetic field corresponding to a change in the distance between the first magnetic element and the at least one sensor, so that the controller can determine the rotation state of the knob element based on the change in the first magnetic field.

2. The function control module as described in claim 1 further includes an assembly base, which is detachably disposed on the keyboard, the knob is rotatably assembled on the assembly base and together with the assembly base surrounds a first receiving space, and the first magnetic element is located in the first receiving space.

3. The function control module as described in claim 2 further includes a button that is pressably disposed between the knob and the assembly base.

4. The function control module as described in claim 3, wherein the assembly base has a first channel portion, the knob has a second channel portion, the first channel portion is fitted into the second channel portion in a direction away from the keyboard and communicates with the second channel portion, and the button extends from the second channel portion toward the keyboard into the first channel portion.

5. The function control module as described in claim 4, wherein the button includes a pressing portion and an extension portion, the pressing portion being located within the first channel portion, the diameter of the pressing portion being larger than the inner diameter of the first channel portion, such that the pressing portion is used to abut against the end of the first channel portion away from the keyboard, and the extension portion being connected to the pressing portion and extending from the second channel portion toward the keyboard into the first channel portion.

6. The function control module as described in claim 3 further includes a second magnetic element, the button having a second receiving space, and the second magnetic element being disposed on the button and located in the second receiving space, the at least one sensor being used to sense a change in a second magnetic field corresponding to a change in the distance between the second magnetic element and the at least one sensor, so that the controller can determine the pressing state of the button based on the change in the second magnetic field.

7. The function control module as described in claim 6, wherein the press member is located at the center of the knob member and the assembly base, and the first receiving space surrounds the second receiving space.

8. The function control module as claimed in claim 2, wherein the keyboard includes a circuit board and an assembly board disposed on the circuit board, the assembly base is detachably disposed on the assembly board, and the at least one sensor is electrically connected to the circuit board.

9. The function control module as described in claim 1, wherein the at least one sensor is a Hall sensor or a tunnel magnetoresistive sensor.

10. The function control module as described in claim 1, wherein the number of the at least one sensor is multiple, and the sensors are arranged in an array.
