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, the shift control apparatus includes a housing; a column unit including one end portion rotatably coupled to the housing, protruding from the housing in a radial direction, and operable for shifting; a driving unit provided in the housing and engaged to the column unit to rotate the column unit; and an override unit provided in the driving unit to transmit driving force to the column unit, and enable the column unit to rotate when external force is applied.
Claims15
A shift control apparatus comprising:
- a housing;
- a column unit including one end portion rotatably coupled to the housing, protruding from the housing in a radial direction, and operable for shifting;
- a driving unit provided in the housing and engaged to the column unit to rotate the column unit;
- and
- an override unit provided in the driving unit to transmit driving force to the column unit, and enable the column unit to rotate when external force is applied,
- wherein the driving unit includes:
- a motor fixed in the housing via a support member;
- a worm mounted on a motor axis of the motor;
- a worm wheel engaged with the worm;
- an intermediate gear mounted on a shaft and disposed coaxially with the worm wheel, and
- the override unit connecting the worm wheel and the intermediate gear,
- wherein the override unit includes:
- a first override gear unit formed on a second edge portion on 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, and
- wherein the intermediate gear engages with a sector gear formed on the one end portion of the column unit.

A shift control apparatus comprising:
- a housing;
- a column unit including one end portion rotatably coupled to the housing, protruding from the housing in a radial direction, and operable for shifting;
- a driving unit provided in the housing and engaged to the column unit to rotate the column unit;
- and
- an override unit provided in the driving unit to transmit driving force to the column unit, and enable the column unit to rotate when external force is applied,
- 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 one end portion of the column unit,
- wherein the column unit 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,
- wherein the standby mode is a position in which the column unit extends from the front of the steering wheel in an upward direction, and
- wherein the use mode is a position in which the column unit rotates from the standby mode and is located to extend in a lateral direction of the steering wheel.

A shift control apparatus comprising:
- a housing located in front of a steering wheel;
- a column unit including one end portion rotatably coupled to the housing, protruding from the housing in a radial direction, and operable for shifting;
- a driving unit provided in the housing, and rotating the column unit according to a signal from an input unit;
- and
- an override unit provided in the driving unit to transmit driving force to the column unit, and enable the column unit to rotate when external force is applied,
- wherein the column unit is located in a standby mode which is a position extending from the front of the steering wheel in an upward direction, or a use mode which is a position extending in a lateral direction of the steering wheel,
- wherein the override unit is configured to transmit driving force to the column unit so that the column unit rotates by operation of the driving unit to change a position thereof from the standby mode to the use mode or from the use mode to the standby mode, and
- wherein the override unit is configured to rotate the column unit when an external force is applied, to change a position thereof from the standby mode to the use mode or from the use mode to the standby mode.
