[0059] The following is a further detailed explanation of this patent in conjunction with the drawings in the specification.

[0060] A rotatable and adjustable control panel comprises a ring bracket (1), a rubber ring (2), a magnetic ring (3), a rotating ring (4), a circuit board (5), and a touch liquid crystal (7);

[0061] The outer surface of the annular bracket (1) in the vertical direction is the outer ring (1.1); the inner diameter of the rubber ring (2) is smaller than the outer diameter of the outer ring (1.1) in a relaxed state, and is larger than the outer diameter of the outer ring (1.1) in a tensioned state; the inner diameter of the magnetic ring (3) is larger than the outer diameter of the outer ring (1.1); the outer diameter of the rubber ring (2) is larger than the inner diameter of the rotating ring (4) in a relaxed state; the outer diameter of the rubber ring (2) is smaller than the inner diameter of the rotating ring (4) in a compressed state; and the inner diameter of the rotating ring (4) is larger than the outer diameter of the magnetic ring (3); this arrangement ensures that the rubber ring has a certain interference fit, eliminates gaps, and produces a damping effect during rotation.

[0062] The rubber ring (2) is sleeved outside the outer ring (1.1) of the annular support (1), the magnetic ring (3) is sleeved outside the outer ring (1.1) of the annular support (1) and is located below the rubber ring (2), and the rotating ring is sleeved outside the rubber ring (2).

[0063] The circuit board (5) is arranged inside the inner surface of the annular bracket (1) in the vertical direction. The circuit board (5) can be powered and includes a connector. The touch liquid crystal (7) includes a cable and is fixed to the annular bracket (1). The touch liquid crystal (7) includes a display liquid crystal cable (7.1) and a touch panel cable (7.2) connected to the touch panel connector (5.2) and the display liquid crystal connector (5.3) of the circuit board (5).

[0064] The magnetic ring (3) is wound with soft magnets, and the ends are spliced ​​with bevels. This ensures that the magnetic ring (3) can send signals to the magnetic field angle sensor (5.1) at any position during rotation. In traditional technology, the magnetic ring (3) is spliced ​​with vertical surfaces. In order to facilitate processing and assembly, the soft magnets need to be processed into long strips of fixed length during mass production. However, there are processing deviations. If it is too long, the excess magnetic strips need to be cut off after pasting, and the processing is troublesome. If it is processed to be slightly shorter and spliced ​​with vertical surfaces, there will be a missing section at the connection. If the missing section is aligned with the sensor, the signal will be discontinuous. Therefore, bevels are used for staggered splicing to ensure that the soft magnets at any position can generate signals to the sensor.

[0065] The rubber ring (2) is clamped by the outer ring (1.1) and the inner rotating surface of the rotating ring (4), and is provided with an interference fit to generate a certain damping. The rotating ring (4) and the rubber ring (2) are positioned up and down axially by the step (1.5) of the annular bracket (1) and the convex ring (6.3) of the base (6). The convex ring (6.3) of the base (6) supports the lower side surface of the lower boss (4.2) of the rotating ring (4), and the upper side surface of the upper boss (4.1) of the rotating ring supports the rubber ring (2). A small amount of gap is left between the rubber ring and the upper side surface of the upper boss (4.1) of the rotating ring and the lower side surface of the step (1.5) of the annular bracket (1). The gap is filled by the deformation of the rubber ring due to the interference fit to reduce shaking.

[0066] More than two screw columns (1.3) are arranged inside the inner surface of the annular bracket (1), two of which are arranged to position the circuit board (5);

[0067] The rotatable adjustable control panel also includes a base (6), on which a plurality of screw column holes (6.1) and connecting holes (6.2) are arranged, and the screw columns (1.3) of the annular bracket 1 are inserted into the screw column holes (6.1), so that the annular bracket (1) is positioned.

[0068] The rotatable adjustable control panel also includes screws, which are fixed into the holes of the screw columns (1.3) through the connecting holes (6.2), thereby fixing the base (6) and the annular bracket 1, and also fixing the circuit board 5, the rotating ring 4 and the rubber ring 2.

[0069] The annular bracket (1) is provided with a square hole (1.2), a magnetic field angle sensor (5.1) is provided on the circuit board (5), and the square hole (1.2) is arranged to be aligned with the magnetic field angle sensor (5.1) on the circuit board (5).

[0070] The rotating ring (4) is provided with an upper boss (4.1) and a lower boss (4.2), the magnetic ring (3) is limited by the upper boss (4.1) and the lower boss (4.2) on the upper boss (4.1) and the lower boss (4.2), and the magnetic ring (3) is glued and fixed on the inner side of the rotating ring 4.

[0071] The rotatable and adjustable control panel also includes a rear cover (8), a power supply module (9), and an iron frame (10); the rear cover (8) is fixed to the power supply module (9) via a rear cover hook (8.1); the pin header (5.2) on the circuit board (5) is connected to the circuit board socket of the power supply module 9 via a pin header hole (8.2); and the lower shell hook (9.1) of the power supply module (9) is fixed to the iron frame 10.

[0072] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
