Abstract:
1. A portable electronic device comprising: a shell comprising a sidewall, two rails, a cantilever, a shaft and a hook, the sidewall defining a first hole and a second hole arranged in a line, the rails, the cantilever, the shaft and the hook protruding from an inner surface of the sidewall, the rails substantially extending along the arrangement direction of the first hole and the second hole and located at two sides of the second hole, the cantilever and the shaft being located between the first hole and the second hole, the cantilever being adjacent to the second hole and comprising a first lever section extending from the inner surface of the sidewall, the hook being located at a side of the first hole opposite to the shaft; an actuation member comprising an operation portion and an engagement portion extending from the operation portion, the operation position being positioned the outside of the shell, the engagement portion passing through the first hole into the inside of the shell, the engagement portion being capable of sliding in the first hole along a direction parallel to the arrangement direction of the first hole and the second hole; a latching member comprising a sliding block slidable on the rails and a tongue extending from a side of the sliding block and received in the second hole, the sliding block comprising a surface opposite to the inner surface of the sidewall and defining a first guiding groove and a second guiding groove in the surface, the first guiding groove being V-shaped and having an apex section adjacent to the tongue and a first upper end and a first lower end far away from the tongue, the second guiding groove curving away from the first guiding groove and having a second upper end and a second lower end respectively communicating with the first upper end and the first lower end, the depth of the second groove gradually increasing from the second upper end to the second lower end, the sliding block comprising a first stop portion at the first lower end and a second stop portion at an end of the apex section adjacent to the first upper end; a transmission member comprising a rack element, a gear element, and a wire element, the rack element comprising a receiving portion engaged with the engagement portion and a toothed rack extending from the receiving portion along the arrangement direction of the first hole and the second hole, the gear element being wheel-shaped, comprising a toothed section meshed with the toothed rack, and defining a shaft hole through which the shaft rotatably inserted and a wire-receiving hole adjacent to an end of the toothed section, the wire element being substantially a straight wire having a first and a second bent distal sections, the first distal section being received in the wire-receiving hole, the second distal section capable of being driven by the gear element to slide in the first and second guiding grooves, the second distal section being configured to resist again the first stop portion to push the sliding block to slide along the rails such that the tongue moves out of the second hole, the second distal section being also configured to hook the second lower end to pull the sliding block to slide along the rails such that the tongue moves in the second hole; a first spring connecting the receiving portion to the hook and configured for pulling the receiving portion; and a second spring connecting the wire element to the first lever section and configured for pulling the wire element.
