Dependent claims

A scroll wheel module with a touch sensing mechanism, installed in a housing, wherein the scroll wheel module comprises:

a scroll wheel body, pivotally connected to the housing, wherein the middle of the scroll wheel body is provided with a cavity;
a touch sensing element, installed in the cavity, wherein one end of the touch sensing element comprises a connecting portion and another end of the touch sensing element comprises a fixing portion;
the connecting portion is pivotally connected to the scroll wheel body;
and the fixing portion extends out of the scroll wheel body and is connected to the housing;
and
an encoding element, connected to the scroll wheel body, wherein the encoding element is located on a side of the scroll wheel body away from the fixing portion;
and the encoding element rotates along with the scroll wheel body, wherein
the touch sensing element can generate a position recognition signal according to a touched position on the scroll wheel body.
