Electronic device and motor assembly thereof

A motor assembly, comprising:

• a drive motor, comprising a shaft;
• a gear, fixedly attached to the shaft;
• a rotation output shaft, comprising a gear teeth portion coupled to the gear;
• a displacement mechanism, synchronizing with the shaft and separated from the rotation output shaft, the displacement mechanism comprising a linear motion component;
• and
• a latch, connected to the linear motion component;
• wherein the displacement mechanism further comprises:
• a screw rod, the linear motion component is threadedly engaged with the screw rod;
• and
• a guide rail, extending parallel to the screw rod and connected to the linear motion component, wherein the drive motor is configured to drive the screw rod to rotate, so that the linear motion component is driven by a thread on the screw rod to move on the guide rail.

An electronic device, comprising:

• a function module;
• a body, comprising an accommodation space, the accommodation space being configured to accommodate the function module;
• and
• a motor assembly, comprising:
• a drive motor, comprising a shaft;
• a gear, fixedly attached to the shaft;
• a rotation output shaft, comprising a gear teeth portion coupled to the gear, the rotation output shaft being connected to the function module and configured to drive the function module to rotate;
• a displacement mechanism, synchronizing with the shaft and separated from the rotation output shaft, the displacement mechanism comprising a linear motion component;
• and
• a latch, connected to the linear motion component and configured to limit the function module.
