Abstract
A locking device is described. The locking device is utilized to lock and unlock a removable device and especially to be suitable for locking and unlocking the removable device of a notebook computer. The locking device has a latch, an elastic member and a sliding switch. The latch engages a fixing indention of the removable device to fix the removable device. The elastic member provides a force to push the latch forward and a recess for retracting the latch backward. The sliding switch utilizes a stud to glidingly couple to a sliding surface of the latch so that the movements of the sliding switch and the latch form a predetermined included angle, preferably of about 90 degrees.
Claims20
A locking device comprising:
- a latch comprising a sliding inclined surface and moving along a predetermined direction forward and backward;
- an elastic member coupling to the latch, the elastic member pushing the latch forward for engaging into a fixing indentation of a removable device, and the latch moving backward to compress the elastic member when the latch is pressed upon by a shell of the removable device;
- and
- a sliding switch coupling to the latch, a predetermined included angle formed between the latch and the sliding switch when movement, wherein the sliding switch comprises a stud and the stud contacts the sliding inclined surface, the stud pressing on the sliding inclined surface to disengage the latch from the fixing indentation of the removable device when the sliding switch is pushed to release the removable device.
A removable device module with a locking device comprising:
- a fixing container;
- a removable device comprising a shell and a fixing indentation, wherein the removable device is capable of inserting into and withdrawing from the fixing container;
- and
- a locking device configured beside the fixing container, the locking device locking the removable device when the removable device is inserted into the fixing container, wherein the locking device further comprises:
- a latch having a sliding inclined surface and moving along a predetermined direction forward and backward;
- an elastic member coupling to the latch, wherein when the removable device inserts into the fixing container, the latch is pressed by the shell of the removable device so that the latch moves backward to compress the elastic member until the fixing indentation arrives in front of the latch and the elastic member pushes the latch forward to engage into the fixing indentation of the removable device to fix the removable device within the fixing container;
- and
- a sliding switch coupling to the latch, a predetermined included angle formed between the latch and the sliding switch when movement, wherein the sliding switch comprises a stud and the stud glidingly couples to the sliding inclined surface and presses on the sliding inclined surface to retract the latch from the fixing indentation of the removable device when the sliding switch is pushed to release the removable device.
A notebook computer having a removable device module with a locking device comprising:
- a removable device module fixing container installed in the notebook computer;
- a removable device comprising a shell and a fixing indentation, wherein the removable device is capable of inserting into and withdrawing from the removable device module fixing container;
- and
- a locking device configured beside the removable device module fixing container, the locking device locking the removable device when the removable device is inserted into the removable device module fixing container, wherein the locking device further comprises:
- a latch having a sliding inclined surface and moving along a predetermined direction forward and backward;
- an elastic member coupling to the latch, wherein when the removable device inserts into the removable device module fixing container, the latch is pressed upon by the shell of the removable device so that the latch moves backward to compress the elastic member until the fixing indentation arrives in front of the latch and the elastic member pushes the latch forward to engage into the fixing indentation of the removable device to fix the removable device within the removable device module fixing container;
- and
- a sliding switch coupling to the latch, an included angle formed between the latch and the sliding switch when movement, wherein the sliding switch comprises a stud and the stud glidingly couples to the sliding inclined surface and presses on the sliding inclined surface to retract the latch from the fixing indentation of the removable device when the sliding switch is pushed to release the removable device.
