RATCHET MODULE AND ELECTRONIC APPARATUS HAVING THE SAME

摘要

A ratchet module disposed in an electronic apparatus realizes one-way push-push function for a functional module. The ratchet module includes a first member and a second member meshed with each other with axially extending ratchet such that the second member may be pushed to rotate in one direction with respect to the first member. A torque spring disposed between the two members is twisted to accumulate a restoring force as the second member is moved by the functional module sliding in a housing and rotated with respect to the first member. The second member is served to maintain the position of the functional module. A button is further used in the ratchet module to push the second member to disengage from the first member, allowing the twisted torque spring to rotate the second member automatically in a reverse direction that pushes the functional module to slide reversely in the housing.

主权项

1. A ratchet module, comprising:
a first member comprising a first ratchet extending on an axial direction along a rotation center; a second member comprising a second ratchet extending on the axial direction and facing the first ratchet, the second ratchet meshing with the first ratchet such that the second member is one-way rotatable around the rotation center with respect to the first member; a resilient restoring member connected between the first member and the second member and keeping an engaged status between the first member and the second member such that the first ratchet and the second ratchet securely mesh with each other, the resilient restoring member providing a rotation restoring force for the second member when the second member is one-way rotated with respect to the first member; and a release member for being exerted to push to disengage the second member from the first member such that the second ratchet disengages from the first ratchet.
