Abstract
A mobile device includes a body, a motor, a transmission assembly and two driven components. The motor and the transmission assembly are disposed at the body. The transmission assembly includes a differential, two shafts and two stoppers. The differential is coupled to the motor. The two shafts are respectively coupled to the two opposite sides of the differential. The two stoppers are respectively disposed corresponding to the two shafts. The two driven components are respectively connected to the two shafts. When one of the two shafts is locked by the corresponding stopper, the motor may still drive the other shaft and the driven component connected thereto to rotate relative to the body through the differential. A transmission assembly is also provided.
Claims19
A mobile device comprising:
- a body;
- a motor, disposed at the body;
- a transmission assembly, disposed at the body, the transmission assembly comprising:
- a first differential, coupled to the motor;
- a first shaft, coupled to one side of the first differential;
- a second shaft, coupled to another side of the first differential;
- a first stopper, disposed corresponding to the first shaft;
- and
- a second stopper, disposed corresponding to the second shaft;
- a first driven component, connected to the first shaft;
- and
- a second driven component, connected to the second shaft,
- in one state, the first shaft is locked by the first stopper so that the first shaft and the first driven component being unable to rotate relative to the body, and the motor drives the second shaft and the second driven component to rotate relative to the body through the first differential,
- in another state, the second shaft is locked by the second stopper so that the second shaft and the second driven component being unable to rotate relative to the body, and the motor drives the first shaft and the first driven component to rotate relative to the body through the first differential.
A transmission assembly adapted to couple to a motor, the transmission assembly comprising:
- a first differential, coupled to the motor;
- a first shaft, coupled to one side of the first differential;
- a second shaft, coupled to another side of the first differential;
- a first stopper, disposed corresponding to the first shaft;
- and
- a second stopper, disposed corresponding to the second shaft,
- in one state, the first shaft is locked by the first stopper so that the first shaft being unable to rotate, and the motor drives the second shaft to rotate through the first differential,
- in another state, the second shaft is locked by the second stopper so that the second shaft being unable to rotate relative to the body, and the motor drives the first shaft to rotate relative to the body through the first differential.
