Locking device and functional module
View Patent ↗A locking device and a functional module including the locking device are provided. The locking device includes a mounting frame with a latching column, and a locking assembly locking or releasing the mounting frame. The locking assembly includes a main body pivotally connected with the mounting frame, a latch rotatably connected with the main body, and a sliding cover slidably mounted on the main body and can drive the latch to rotate relative to the main body. When the latch is engaged with the latching column, the locking assembly is locked to the mounting frame. When the sliding cover is moved relative to the main body, the latch rotates relative to the main body to disengage from the latching column. The latch does not need to be rotated separately, and unlocking efficiency of the locking device is improved.

wherein the latch defines a rail slot, the main body defines at least one guiding slot, the rail slot communicates with the at least one guiding slot in a thickness direction of the latch, the rail slot is inclined with respect to the at least one guiding slot, a first movable column is disposed on the sliding cover, the first movable column is inserted into the rail slot and the at least one guiding slot, a first stop column is disposed on the mounting frame, the first stop column and the latching column are staggered, and the first stop column is configured to abut against a side of the latch away from the latching column to drive the latch to rotate relative to the main body;
wherein when the latch is engaged with the latching column, the locking assembly is locked to the mounting frame,
wherein when the first stop column abuts against the side of the latch away from the latching column and the sliding cover is moved relative to the main body, the first movable column moves along the at least one guiding slot and the rail slot, and the first movable column abuts against different heights of the rail slot and rotates the latch relative to the main body, such that the latch is disengaged from the latching column.
2. The locking device of claim 1 , wherein a second movable column is disposed on the sliding cover, the second movable column and the first movable column are spaced from each other, the main body defines two guiding slots for the first movable column and the second movable column to pass through respectively, the two guiding slots are configured to guide the first movable column and the second movable column, and the rail slot communicates with one of the two guiding slots.
3. The locking device of claim 2 , wherein the rail slot comprises a first slot portion and a second slot portion intercommunicating with each other, the second slot portion is inclined relative to the first slot portion, the first slot portion is aligned with the one of the two guiding slots.
4. The locking device of claim 3 , wherein a second stop column is disposed on the mounting frame, the second stop column protrudes towards the main body and is on a same side as the first stop column, the second stop column is configured to abut against the main body to drive the first movable column to move relative to the main body until the first movable column is moved to the first slot portion.
5. The locking device of claim 1 , wherein the latch is elastically connected with the main body.
6. The locking device of claim 1 , wherein the latch is accommodated in the sliding cover, the sliding cover defines an opening, and the latch extends out of the opening.
7. A functional module comprising a locking device, wherein the locking device comprises:
a mounting frame with a latching column; and
a locking assembly configured to lock or release the mounting frame, the locking assembly comprises:
a main body pivotally connected with the mounting frame;
a latch rotatably connected with the main body; and
a sliding cover slidably mounted on the main body and configured to drive the latch to rotate relative to the main body,
wherein the latch defines a rail slot, the main body defines at least one guiding slot, the rail slot communicates with the at least one guiding slot in a thickness direction of the latch, the rail slot is inclined with respect to the at least one guiding slot, a first movable column is disposed on the sliding cover, the first movable column is inserted into the rail slot and the at least one guiding slot a first stop column is disposed on the mounting frame, the first stop column and the latching column are staggered, and the first stop column is configured to abut against a side of the latch away from the latching column to drive the latch to rotate relative to the main body;
wherein when the latch is engaged with the latching column, the locking assembly is locked to the mounting frame,
wherein when the first stop column abuts against the side of the latch away from the latching column and the sliding cover is moved relative to the main body, the first movable column moves along the at least one guiding slot and the rail slot to rotate the latch relative to the main body, such that the latch is disengaged from the latching column.
8. The functional module of claim 7 , wherein a second movable column is disposed on the sliding cover, the second movable column and the first movable column are spaced from each other, the main body defines two guiding slots for the first movable column and the second movable column to pass through respectively, the two guiding slots are configured to guide the first movable column and the second movable column, and the rail slot communicates with one of the two guiding slots.
9. The functional module of claim 8 , wherein the rail slot comprises a first slot portion and a second slot portion intercommunicating with each other, the second slot portion is inclined relative to the first slot portion, the first slot portion is aligned with the one of the two guiding slots.
10. The functional module of claim 9 , wherein a second stop column is disposed on the mounting frame, the second stop column protrudes towards the main body and is on a same side as the first stop column, the second stop column is configured to abut against the main body to drive the first movable column to move relative to the main body until the first movable column is moved to the first slot portion.
11. The functional module of claim 7 , wherein the latch is elastically connected with the main body.
12. The functional module of claim 7 , wherein the latch is accommodated in the sliding cover, the sliding cover defines an opening, and the latch extends out of the opening.
