Abstract

An unlock device includes at least one operating member, a first unlock module and a second unlock module. The at least one operating member is movably disposed on a frame, wherein the frame is equipped with a first lock mechanism and a second lock mechanism. The first unlock module is movably disposed on the frame and connected to the first lock mechanism. The second unlock module is movably disposed on the frame and connected to the second lock mechanism. The at least one operating member moves to drive the first unlock module to move to unlock the first lock mechanism or drive the second unlock module to move to unlock the second lock mechanism.

First claim

What is claimed is:

1. An unlock device comprising:
at least one operating member movably disposed on a frame, the frame being equipped with a first lock mechanism and a second lock mechanism;
a first unlock module movably disposed on the frame and connected to the first lock mechanism, the first unlock module comprising a first sliding member slidably disposed on the frame;
a second unlock module movably disposed on the frame and connected to the second lock mechanism, the second unlock module comprising a second sliding member slidably disposed on the frame; and
a selecting member movably disposed on the frame, the first sliding member and the second sliding member moving as the selecting member moves;
wherein the at least one operating member moves to drive the first unlock module to move to unlock the first lock mechanism or drive the second unlock module to move to unlock the second lock mechanism.

2. The unlock device of claim 1 , wherein the selecting member moves between a first position and a second position with respect to the frame; when the selecting member is located at the first position, the at least one operating member slides to drive the first unlock module to move to unlock the first lock mechanism; and when the selecting member is located at the second position, the at least one operating member slides to drive the second unlock module to move to unlock the second lock mechanism.

3. The unlock device of claim 2 , wherein sliding directions of the first and second sliding members are identical to a sliding direction of the at least one operating member.

4. The unlock device of claim 3 , wherein the first unlock module further comprises a first rotating member pivotally connected to the frame, the second unlock module further comprises a second rotating member pivotally connected to the frame, and the first and second sliding members are configured to drive the first and second rotating members to rotate, respectively.

5. The unlock device of claim 4 , wherein the first rotating member has a first protruding portion, the first sliding member moves to push the first protruding portion to rotate the first rotating member, the second rotating member has a second protruding portion, and the second sliding member moves to push the second protruding portion to rotate the second rotating member.

6. The unlock device of claim 5 , wherein the first sliding member has a first engaging groove, the first protruding portion is slidably disposed in the first engaging groove, the second sliding member has a second engaging groove, and the second protruding portion is slidably disposed in the second engaging groove.

7. The unlock device of claim 4 , wherein the first rotating member has a first connecting member, the first connecting member is eccentric with respect to a rotation center of the first rotating member and connected to the first lock mechanism, the second rotating member has a second connecting member, and the second connecting member is eccentric with respect to a rotation center of the second rotating member and connected to the second lock mechanism.

8. The unlock device of claim 3 , wherein the selecting member has a first receiving hole and a second receiving hole, an end of the first sliding member is slidably inserted into the first receiving hole, and an end of the second sliding member is slidably inserted into the second receiving hole.

9. The unlock device of claim 4 , wherein the first sliding member comprises a first sliding portion, a first driving portion and a first restricting portion, the first sliding portion is slidably inserted into the selecting member, the first driving portion is connected to the first rotating member, the first restricting portion is disposed at a side of the first driving portion, the second sliding member comprises a second sliding portion, a second driving portion and a second restricting portion, the second sliding portion is slidably inserted into the selecting member, the second driving portion is connected to the second rotating member, the second restricting portion is disposed at a side of the second driving portion.

10. The unlock device of claim 3 , wherein a first accommodating space is formed between the first sliding member and the at least one operating member or between the first sliding member and the selecting member, and a second accommodating space is formed between the second sliding member and the at least one operating member or between the second sliding member and the selecting member.

11. The unlock device of claim 2 , wherein an elastic member is disposed between the selecting member and the frame and configured to make the selecting member away from the first position.

12. The unlock device of claim 11 , wherein the elastic member provides an elastic force to force the selecting member to return to the second position.

13. The unlock device of claim 11 , wherein the frame has a protruding block, an end of the elastic member is sleeved on the protruding block and abuts against the frame, and another end of the elastic member abuts against the selecting member.

14. The unlock device of claim 1 , wherein the at least one operating member comprises a first operating member and a second operating member, the first operating member slides to drive the first unlock module to move to unlock the first lock mechanism, and the second operating member slides to drive the second unlock module to move to unlock the second lock mechanism.

15. The unlock device of claim 1 , further comprising a retaining mechanism disposed on the at least one operating member, the retaining mechanism retaining the at least one operating member at an unlock position when the at least one operating member slides to unlock one of the first lock mechanism and the second lock mechanism, the retaining mechanism releasing the at least one operating member when the at least one operating member is actuated from the unlock position.

16. The unlock device of claim 15 , wherein the retaining mechanism comprises a first engaging member and a second engaging member, the first engaging member is fixed on the at least one operating member, the second engaging member is connected to the frame, the first engaging member has a first inclined groove, a second inclined groove, a third inclined groove and a fourth inclined groove connected to each other, an engaging portion of the second engaging member moves along the first and second inclined grooves and then engages in a recess between the second and third inclined grooves to retain the at least one operating member at the unlock position, and the engaging portion of the second engaging member disengages from the recess and moves along the third and fourth inclined grooves to release the at least one operating member.

17. The unlock device of claim 15 , wherein the retaining mechanism is pivotally connected to the at least one operating member and comprises an engaging portion and an elastic portion, the frame has an engaging hole, the engaging portion abuts against the frame and the elastic portion is compressed by the frame before the at least one operating member slides to unlock the second lock mechanism, and the elastic portion drives the retaining mechanism to rotate and the engaging portion engages in the engaging hole when the at least one operating member slides to unlock the second lock mechanism.
