Abstract:
The present application relates to a transmission mechanism (32), a driving device (30) and an electronic apparatus (100). The transmission mechanism (32) comprises a lead screw (321), a transmission member (322) and a guide assembly (323). The lead screw (321) and the transmission member (322) are sleeved together in such a way that both can rotate relative to each other. The lead screw (321) has an outer raceway (321a), and the transmission member (322) has an inner raceway (322a), wherein the outer raceway (321a) and the inner raceway (322a) together define a spiral channel (32b) for configuring balls (32a). When the lead screw (321) rotates relative to the transmission member (322), the guide assembly (323) can guide the ball (32a) moving out of the spiral channel (32b) to circularly roll into the spiral channel (32b). The transmission member (322) is provided with a first through hole (3221) and a second through hole (3222), wherein the first through hole (3221) and the second through hole (3222) are both in communication with the spiral channel (32b) so as to guide the ball (32a) to enter or move out of the spiral channel (32b).
