Abstract

A latch module includes a fixing member and a sliding member. A first surface of the fixing member is configured to align and engage with a mounting surface of a detachable device. A sliding unit of the sliding member is relative to a guiding unit of the fixing member and allows the sliding member to slide linearly with respect to the fixing member. The sliding member includes a pushing portion corresponding to a switching column on a resilient arm of the fixing member. While the sliding member is slid to a first position, the switching column is away from the pushing portion and a convex portion of the resilient arm tends to push against the mounting surface. While the sliding member is slid to a second position, the pushing portion pushes the switching column to drive the convex portion away from the mounting surface.

First claim

What is claimed is:

1. A latch module, comprising:
a fixing member comprising a first surface, a second surface, an opening, a resilient arm and a guiding unit, wherein the first surface and the second surface are opposite to each other, and the first surface is configured to align and attach to a mounting surface of a detachable device, wherein the opening passes through the first surface and the second surface, and the resilient arm is received within the opening and comprises a first end connected with an edge of the opening and a second end opposite to the first end, wherein the resilient arm comprises a convex portion and at least one switching column, wherein the convex portion is disposed on the second end of the resilient arm, located at a first side of the opening and protrudes along a direction from the second surface to the first surface, wherein while the mounting surface is attached to the first surface, the convex portion tends to push against the mounting surface, wherein the at least one switching column is relative to the convex portion and located at a second side of the opening, wherein the guiding unit is disposed on two lateral sides of the fixing member; and
a sliding member comprising at least one pushing portion and a sliding unit, wherein the sliding unit is disposed on two lateral sides of the sliding member and configured with and relative to the guiding unit of the fixing member so that the sliding member slides linearly with respect to the fixing member along a first direction or a second direction, wherein the first direction and the second direction are opposite to each other, wherein while the sliding member is in a first position relative to the fixing member, the at least one switching column is separated from an end of the at least one pushing portion and the resilient arm maintains an elastic force, wherein while the sliding member is in a second position relative to the fixing member, the at least one pushing portion pushes against the at least one switching column to drive the at least one switching column away from the second surface and drive the convex portion of the resilient arm away from the first surface along a direction from the first surface to the second surface.

2. The latch module according to claim 1 , wherein the latch module is constructed on a housing, wherein the detachable device is detachably connected to the housing along the first direction, and the detachable device is detached from the housing along the second direction.

3. The latch module according to claim 2 , wherein the sliding member comprises a first engaging portion disposed on an end of the sliding member, wherein the detachable device comprises a second engaging portion disposed nearby an edge of the mounting surface and relative to the first engaging portion, wherein while the detachable device is detachably connected to the housing along the first direction, the first engaging portion and the second engaging portion are engaged with each other.

4. The latch module according to claim 2 , wherein while the sliding member is in a third position relative to the fixing member, the at least one switching column is separated from another end of the at least one pushing portion, the convex portion of the resilient arm is engaged with a recess of the detachable device, wherein the detachable device is connected and fastened within the housing.

5. The latch module according to claim 4 , wherein the slide number comprises a stopper portion relative to the resilient arm, wherein while the sliding member is in the third position relative to the fixing member, the stopper portion prevents the resilient arm from being displaced along the direction from the first surface to the second surface.

6. The latch module according to claim 1 wherein the slide number comprises a stopper portion relative to the resilient arm, wherein while the sliding member is in the first position relative to the fixing member, the stopper portion prevents the resilient arm from being displaced along the direction from the first surface to the second surface.

7. The latch module according to claim 1 , wherein the detachable device comprises a recess disposed on the mounting surface and relative to the convex portion, wherein while the mounting surface is attached to the first surface and the convex portion tends to push against the mounting surface, the convex portion and the recess are engaged with each other.

8. The latch module according to claim 1 , wherein the convex portion comprises an inclined plane increasing protrusion along the first direction, wherein while the detachable device is detachably connected to the housing along the first direction, the detachable device pushes against the inclined plane and the convex portion tends to push against the mounting surface.

9. The latch module according to claim 1 , wherein the guiding unit and the sliding unit are a concave rail and a convex rail, respectively.

10. The latch module according to claim 1 , wherein the at least one switching column comprises two switching columns disposed on two lateral sides of the resilient arm, respectively, wherein the at least one pushing portion comprises two protruding rails disposed nearby the sliding unit and relative to the two switching columns, respectively, wherein while the sliding member is in the second position relative to the fixing member, the two protruding rails push against the two switching columns to drive the two switching columns away from the second surface and the convex portion of the resilient arm away from the first surface along the direction from the first surface to the second surface.

11. The latch module according to claim 1 , wherein the sliding member comprises a protruding handle disposed on an end of the sliding member and configured to drive the sliding member to slide with respect to the fixing member along the first direction or the second direction.

12. A detachable assembling structure comprising:
a housing comprising at least one lateral side, at least one receiving slot and at least one receiving opening;
at least one detachable device, wherein the detachable device is configured to be detachably received within the receiving slot along a first direction through the receiving opening, or separated from the receiving slot along a second direction through the receiving opening, wherein the first direction and the second direction are opposite to each other, wherein the detachable device comprises at least one mounting surface and at least one recess, and the recess is disposed on the mounting surface; and
a latch module passing through the lateral side of the housing and comprising:
a fixing member comprising a first surface, a second surface, an opening, a resilient arm and a guiding unit, wherein the first surface and the second surface are opposite to each other, and the first surface is communicated with the receiving slot, wherein while the detachable device is received within the receiving slot, the first surface and the mounting surface are attached to each other, wherein the opening passes through the first surface and the second surface, and the resilient arm is received within the opening and comprises a first end connected with an edge of the opening and a second end opposite to the first end, wherein the resilient arm comprises a convex portion and at least one switching column, wherein the convex portion is disposed on the second end of the resilient arm, located at a first side of the opening and protrudes along a direction from the second surface to the first surface, wherein while the mounting surface is attached to the first surface, the convex portion tends to push agai
