Abstract
In a column-type electronic shift control apparatus of which position may be varied not only by driving a driving unit but also by a predetermined amount of external force, and which may prevent unintentional shifting when the position is changed by the predetermined amount of external force, and a method for controlling the same, the shift control apparatus includes a housing; a column module including a module body rotatably coupled to the housing, and a shift lever rotatably hinged relative to the module body and protruding from the housing; and a driving unit provided in the housing and engaged to the module body to rotate the module body.
Claims13
A shift control apparatus comprising:
- a housing;
- a column module including a module body rotatably coupled to the housing, and a shift lever rotatably hinged relative to the module body and protruding from the housing;
- and
- a driving unit disposed in the housing and engaged to the module body to rotate the module body,
- wherein the housing is fixed on a steering column in front of a steering wheel,
- wherein the steering column passes through the housing and the module body together, and
- wherein the column module rotates around the steering column in response that the driving unit operates, and changes a position thereof to a standby mode or a use mode.
A shift control apparatus comprising:
- a housing;
- a column module including a module body rotatably coupled to the housing, and a shift lever rotatably hinged relative to the module body and protruding from the housing;
- and
- a driving unit provided in the housing and engaged to the module body to rotate the module body,
- wherein a sector gear is formed on a first side of the module body,
- wherein the driving unit includes:
- a motor fixed in the housing;
- a gear unit engaging with the sector gear and transmitting driving force of the motor to the sector gear;
- and
- a shaft rotating and supporting at least a portion of the gear unit,
- wherein the gear unit includes:
- a worm mounted on a motor axis of the motor;
- a worm wheel engaged with the worm;
- an intermediate gear fixedly mounted on the shaft and disposed coaxially with the worm wheel;
- and
- an override unit connecting the worm wheel and the intermediate gear,
- wherein the intermediate gear engages with the sector gear,
- wherein the override unit allows the intermediate gear to rotate relative to the worm wheel when external force is applied,
- wherein the override unit includes:
- a first override gear unit formed on an end portion of an internal surface of the worm wheel;
- a plurality of spline groove portions formed on an internal surface of a side wall in an accommodation groove of the intermediate gear;
- an override ring member in which a second override gear unit engaged with the first override gear unit is formed on a first side, and a plurality of spline protrusions at least partially fitted into each of the spline groove portions are formed on a second side;
- and
- an elastic member located between the accommodation groove and the override ring member.
