Sphere-type shift control apparatus for electronic transmission system
A sphere-type shift control apparatus for an electronic transmission system includes a shift operation unit configured to be operated by a driver of a vehicle for gear shifting on a first hemisphere of a spherical mechanism and a design unit for indirect illumination and image transmission on a second hemisphere of the spherical mechanism. By rotating the spherical mechanism, only the shift operation unit is exposed to a vehicle interior through an opening of a housing when a shift operation is required, while only the design unit is exposed to the vehicle interior through the opening of the housing when the shift operation is not required.
1. A sphere shift control apparatus for electronic transmission system, comprising:
a spherical mechanism having a rotary shaft coupled through a center of the spherical mechanism; and
a housing to which the spherical mechanism is rotatably coupled via the rotary shaft, wherein:
the spherical mechanism has three planes formed on a surface of the spherical mechanism, the three planes being continuously interconnected;
the spherical mechanism comprises a gear shift provided on a first plane of the spherical mechanism;
the spherical mechanism comprises a light source provided on a second plane of the spherical mechanism to realize indirect illumination;
the spherical mechanism comprises a display provided on a third plane of the spherical mechanism to transmit a specific image through an illumination window; and
wherein a portion of the spherical mechanism facing with the first plane of the spherical mechanism is opened in a radially outward direction from the center of the spherical mechanism such that a driver operates gear shifting through the opened portion of the spherical mechanism.
2. The sphere shift control apparatus according to claim 1 , further comprising a first PCB coupled to the spherical mechanism, wherein the first PCB is configured to receive an operation signal from the gear shift and configured to output a control signal to a transmission control unit (TCU).
3. The sphere shift control apparatus according to claim 2 , further comprising a motor fixed to the housing and connected to the rotary shaft to rotate the rotary shaft,
wherein either the first PCB or the second PCB configured to control the motor to be driven.
4. The sphere shift control apparatus according to claim 1 , further comprising a second PCB coupled to the spherical mechanism, wherein the second PCB is configured to control the light source to be turned on/off and operation of the display.
5. The sphere shift control apparatus according to claim 1 , wherein the spherical mechanism is configured to rotate about the rotary shaft by 120 degrees, so that only one of the first to third planes is exposed to a vehicle interior.
