Technical Field

The invention relates to the technical field of knobs, in particular to a novel capacitive knob.

Technical Field

In the existing vehicle-mounted market, automotive interior parts such as an automobile air conditioner, a display module, a navigation part and the like have structures with additional knobs for function adjustment. The difference between the knob structure arranged on the touch screen and the traditional knob structure is that the change of capacitance is brought by the position change of a bottom metal induction sheet in the rotating operation process, and the sensing knob operation is realized by utilizing an induction IC and a software algorithm on the touch screen so as to realize function adjustment, such as the modules of an automobile air conditioner panel, a navigation display panel and the like, and the function adjustment is realized as shown in the attached figures 1-2.

The knob structure has a defect that the knob must be completely arranged in a screen, and a metal induction sheet is contacted with any gear, so that limitations and limitations are caused on modeling and spatial arrangement. For this reason, the arrangement of the knob is limited, the knob needs to be completely within the visible area of the touch screen, the size and the aesthetic proportion of the touch screen and the knob need to be considered, obvious constraints are imposed on the modeling of the car factory, and the size of the screen is limited and cannot be too small.

Disclosure of Invention

The invention aims to provide a novel capacitive knob, and the technical scheme provided by the invention is adopted to solve the technical problems that the existing capacitive knob is required to be completely positioned in a visual area of a touch screen, and certain limitations and limitations exist on modeling and spatial arrangement.

In order to solve the above technical problems, the present invention provides a novel capacitive knob, which includes a cylindrical knob body and a knob housing rotatably sleeved outside the knob body; a metal ring is coaxially arranged at the bottom of the knob body; an on-off structure which can be contacted with the metal ring is arranged between the knob body and the knob shell.

Preferably, the on-off structure comprises a contact assembly and a metal elastic sheet assembly;

the contact assembly is arranged on the outer peripheral surface of the knob body and comprises a sliding block capable of sliding along the radial direction of the knob body and an abutting block arranged on the sliding block; a contact piece which can be contacted with the metal ring is fixedly arranged at the bottom of the sliding block;

the metal elastic sheet assembly is arranged on the knob shell and comprises a metal elastic sheet which is arranged at the same height as the abutting block; the metal elastic sheet can be abutted against the abutting block, so that the contact piece moves and is in contact with the metal ring.

Preferably, the contact assembly further comprises a resilient structure; a piston cavity with an inward opening is formed in the sliding block along the radial direction of the knob body; a piston is arranged in the piston cavity in a sliding mode, and a piston head of the piston penetrates through the piston cavity to form the abutting block; and a sealing plug extending into the piston cavity is fixedly arranged on the peripheral surface of the knob body.

Preferably, the piston head is semi-spherical.

Preferably, the metal elastic sheet assembly further comprises a spring arranged along the axial direction of the knob shell; the metal elastic sheet is fixed at the tail end of the spring.

Preferably, the metal elastic sheet is L-shaped.

Preferably, the number of contact assemblies is at least 2.

Compared with the prior small metal sheet, the whole knob is not required to be completely arranged on the screen, so that the knob can be more flexibly and changeably applied to the touch screen, the modeling space is more free, and especially for the touch screen with a small size, the technical scheme of adding the knob structure can be realized.
