Abstract

A knob device includes a lower cover assembly, an upper cover assembly, a limiting member and an annular member. The lower cover assembly includes a first stopping portion. The upper cover assembly is rotatably stacked on the lower cover assembly along an axis. The upper cover assembly has multiple fixing holes. The limiting member is located between the upper cover assembly and the lower cover assembly and fixed to the lower cover assembly. The limiting member includes a body and a second stopping portion extending from the body. The second stopping portion and first stopping portion are arranged up and down along the axis. The annular member is arranged around the body, and the annular member is rotatably arranged between the first stopping portion of the lower cover assembly and the second stopping portion. The first stopping portion and the second stopping portion limit the annular member on the axis. The annular member includes multiple pogo pins retractably protruding from an outer surface. The pogo pins extend into the fixing holes of the upper cover assembly to fix the annular member to the upper cover assembly.

First claim

What is claimed is:

1. A knob device, comprising:
a lower cover assembly, comprising a first stopping portion;
an upper cover assembly, rotatably stacked on the lower cover assembly along an axis, and the upper cover assembly comprising a plurality of fixing holes;
a limiting member, located between the upper cover assembly and the lower cover assembly and fixed to the lower cover assembly, the limiting member comprising a body and a second stopping portion extending from the body and the second stopping portion and the first stopping portion being arranged up and down along the axis; and
an annular member, arranged around the body of the limiting member and rotatably arranged between the first stopping portion of the lower cover assembly and the second stopping portion of the limiting member, the annular member being limited by the first stopping portion of the lower cover assembly and the second stopping portion of the limiting member on the axis and the annular member comprising a plurality of pogo pins retractably protruding from an outer surface of the annular member, wherein the pogo pins extend into the fixing holes of the upper cover assembly to fix the annular member to the upper cover assembly.

2. The knob device according to claim 1 , wherein the upper cover assembly further comprises an inner upper cover and an outer upper cover fixed to the inner upper cover, the fixing holes are formed in the inner upper cover, and a material of the inner upper cover is different from a material of the outer upper cover.

3. The knob device according to claim 2 , wherein the inner upper cover comprises a disk body and a plurality of protruding portions extending from the disk body to a direction opposite to the outer upper cover along the axis, and the fixing holes are formed in the protruding portions.

4. The knob device according to claim 3 , wherein each protruding portion has an inclined surface at an end, and the inclined surface faces the annular member.

5. The knob device according to claim 1 , wherein each fixing hole comprises a first end close to the limiting member and a second end opposite to the first end, and an aperture of the first end is greater than an aperture of the second end.

6. The knob device according to claim 1 , wherein the annular member has a rail portion, and the rail portion is rotatably arranged at the first stopping portion in a sliding manner.

7. The knob device according to claim 1 , wherein the lower cover assembly further comprises an inner lower cover and an outer lower cover fixed to the inner lower cover, the first stopping portion is formed at the inner lower cover, and a material of the inner lower cover is different from a material of the outer lower cover.

8. The knob device according to claim 1 , further comprising a circuit board, wherein the body of the limiting member comprises a bottom wall and a sidewall protruding from the bottom wall, the bottom wall and the sidewall enclose an accommodation space, and the circuit board is located in the accommodation space.

9. The knob device according to claim 8 , further comprising a plurality of first locking members, wherein the lower cover assembly has a plurality of first through holes, the bottom wall comprises a plurality of screw holes corresponding to the first through holes, and the first locking members pass through the first through holes and are screwed to the screw holes to fix the limiting member to the lower cover assembly.

10. The knob device according to claim 1 , further comprising a circuit board and a second locking member, wherein the circuit board comprises a second through hole, the lower cover assembly has a locking hole, and the second locking member passes through the second through hole of the circuit board and is fixed to the locking hole of the lower cover assembly.
