The invention discloses a smart
home exercise device which comprises an
upper limb movement mechanism, the
upper limb movement mechanism comprises a left
handle rod and a right
handle rod. The left
handle rod and the right handle rod are in connection with a left rotating shaft and a first right rotating shaft through a left two-stage
bevel gear transmission and a right two-stage
bevel gear transmission respectively. A left first-stage
bevel gear transmission is connected with a right first-stage bevel
gear transmission through a belt transmission mechanism; a left
clutch is arranged between the left first-stage bevel
gear transmission and the left second-stage bevel
gear transmission; the first right rotating shaft is connected with a second right rotating shaft through a right
clutch; asecond right rotating shaft is provided with a right straight gear through a one-way bearing; the left rotating shaft fixes a left straight gear; a left straight gear and the right straight gear respectively drive left and right racks to ascend; and the left and right racks rises to the set positions to eject out a round ball in a hollow
pipe, the
total transmission ratio of the left two-stage bevel gear is smaller than the
transmission ratio of the right two-stage bevel gear, the ball can be ejected out at a time when the left rack ascends, the right rack continuously ascends through a brakeand a
brake gear, and the desire of a patient for increasing the movement range of the upper limbs is stimulated.
