Knob force transfer module
View Patent ↗A knob assembly comprising a housing, a circuit board, a rotary knob, a rotary actuated potentiometer and a rotation assembly. The housing has a front face. The circuit board is located in the housing, with the circuit board having a front and a rear. The rotary knob extends from the front face of the housing, with the rotary knob being located in front of the circuit board. The rotary actuated potentiometer is connected to the rear of the circuit board. The rotation assembly mechanically transfers a rotation force of the rotary knob to the rotary actuated potentiometer.
1. A knob assembly comprising:
a housing, the housing having a front face;
a circuit board located in the housing, the circuit board having a front and a rear;
a rotary knob extending from the front face of the housing, the rotary knob being located in front of the circuit board;
a rotary actuated potentiometer connected to the rear of the circuit board; and
a rotation assembly for mechanically transferring a rotation force of the rotary knob to the rotary actuated potentiometer, wherein the rotation assembly comprises a shift gear engaged with the rotary actuated potentiometer and a longitudinal gear extending through the circuit board, and the shift gear includes first teeth; the longitudinal gear includes second teeth and third teeth; and the rotary knob includes fourth teeth; and the first teeth engage the second teeth and the third teeth engage the fourth teeth to transmit rotary force from the rotary knob to the rotary actuated potentiometer.
2. The knob assembly of claim 1 , wherein:
the circuit board has a push button actuator for actuating a circuit on the circuit board.
3. The knob assembly of claim 2 , further including:
a push button located within the rotary knob, the push button being configured to slide within the rotary knob to abut the push button actuator to thereby actuate the circuit on the circuit board.
4. The knob assembly of claim 1 , wherein:
the rotation assembly extends through an opening in the circuit board.
5. The knob assembly of claim 1 , wherein:
the housing comprises a module having a front module portion and a rear module portion, the module being configured to be inserted into a slot.
6. A knob assembly comprising:
a housing, the housing having a front face;
a circuit board located in the housing, the circuit board having a front and a rear, the circuit board having a push button actuator for actuating a circuit on the circuit board;
a rotary knob extending from the front face of the housing, the rotary knob being located in front of the circuit board;
a rotary actuated potentiometer connected to the rear of the circuit board;
a rotation assembly for transferring a rotation force of the rotary knob to the rotary actuated potentiometer, wherein the rotation assembly comprises a shift gear engaged with the rotary actuated potentiometer and a longitudinal gear extending through the circuit board, and the shift gear includes first teeth; the longitudinal gear includes second teeth and third teeth; and the rotary knob includes fourth teeth; and the first teeth engage the second teeth and the third teeth engage the fourth teeth to transmit rotary force from the rotary knob to the rotary actuated potentiometer; and
a push button located within the rotary knob, the push button being configured to slide within the rotary knob to abut the push button actuator to thereby actuate the circuit on the circuit board.
7. The knob assembly of claim 6 , wherein:
the rotation assembly extends through an opening in the circuit board.
8. The knob assembly of claim 6 , wherein:
the housing comprises a module having a front module portion and a rear module portion, the module being configured to be inserted into a slot.
9. The knob assembly of claim 6 , further including:
a knob shell fixed in position within the housing, the knob shell having the rotary knob therein.
