DETAILED DESCRIPTION OF INVENTION
Referring to FIG. 1, an embodiment of a latching mechanism B is disposed on the main body M of an electronic device. The electronic device, such as a notebook computer or a mobile communication device, comprises a movable part (not shown) which is slidable or rotatable relative to the main body M. The movable part may comprise the keyboard or cover module of the electronic device, and a movable member C is disposed on the movable part. When the latching mechanism B joins with the movable member C, the movable part of the electronic device is fixed to the main body M.
Referring to FIGS. 1 and 2, the latching mechanism B primarily comprises a rod 10, a rotary member 20, a first latching member 30, a second latching member 40, a button 101, a first elastic member 301, and a second elastic member 401. As shown in FIGS. 1 and 2, the rod 10 is an elongated member, the button 101 is disposed at an end of the rod 10 and exposed to a side of the main body M. The first latching member 30 is disposed on a side of the rod 10 and substantially parallel thereto. The rotary member 20 is disposed between the rod 10 and the first latching member 30, and pivotally connected to the main body M through a pivot 201. Two end portions 202 and 203 of the rotary member 20 are respectively connected to the rod 10 and the first latching member 30. Additionally, the second latching member 40 is fixed to the rod 10 by a connecting member S, and substantially parallel to the rod 10.
As shown in FIGS. 1 and 2, the first and second latching members 30 and 40 are located on the same axis and respectively form first and second latching portions 302 and 402 and first and second grooves 303 and 403. The first and second elastic members 301 and 401 are respectively received in the first and second grooves 303 and 403, wherein an end of the first and second elastic members 301 and 401 are respectively connected to the first and second latching members 30 and 40, and the other end thereof respectively form connecting portions 301′ and 401′ fixed to the main body M. The first and second elastic members 301 and 401 can slide in the grooves 303 and 403 respectively, so as to provide elastic force to join the first and second latching portions 302 and 402 with the movable member C.
Specifically, a slot 304 is formed on the first latching member 30, and an end 202 of the rotary member 20 is received in the slot 304. When the rod 10 moves along the −X direction and forces the rotary member 20 to rotate, the end 202 of the rotary member 20 pushes the first latching member 30 along the X direction.
Referring to FIGS. 1 and 3, two sides of the movable member C respectively form first and second recesses C1 and C2. When the movable member C moves toward the rod 10 to a joining position, the first and second latching portions 302 and 402 of the first and second latching members 30 and 40 engage with the first and second recesses C1, C2 respectively, so as to fix the movable member C to the main body M (FIG. 3).
As shown in FIG. 1, when the movable member C is separated from the main body M, the first and second latching members 30, 40 are located in a predetermined position. When the movable member C moves toward the rod 10 (−Y direction), the movable member 10 pushes the first and second latching members 30 and 40 to move along the X direction (the first direction) and the −X direction (the second direction) respectively and separate from each other, such that the first and second elastic member 301 and 401 are compressed in the grooves 303 and 403.
In FIG. 3, when the movable member C moves toward the rod 10 to the joining position, the first and second latching members 30 and 40 are forced by the first and second elastic members 301 and 401 along the −X direction (the second direction) and the X direction (the first direction) respectively and close to each other, thus returning to the predetermined position. Namely, the first and second latching portions 302 and 402 of the first and second latching members 30 and 40 can respectively join with the first and second recess C1 and C2, so as to fix the movable member C to the main body M.
Referring to FIG. 4, to separate the movable member C from the main body M, an external force F may be applied to the button 101 on the side of the rod 10 along the −X direction. When the button 101 is pushed by an external force F, the rod 10 and the second latching member 40 move along the −X direction, and the rotary member 20 rotates clockwise to push the first latching member 30 along the X direction. Thus, the first and second latching portions 302 and 402 of the first and second latching members 30 and 40 are separated from the first and second recesses C1 and C2 of the movable member C, such that the movable member C can be released and separate from the main body M along the Y direction.
The invention provides an electronic device and a latching mechanism thereof, wherein the latching mechanism is disposed on the main body of the electronic device to join with a movable member. The latching mechanism primarily comprises a rod, a first latching member, a second latching member, a first elastic member, a second elastic member, and a rotary member, wherein the first latching member is disposed on a side of the rod, and the second latching member is connected to the rod. The first elastic member connects the first latching member with the main body, and the second elastic member connects the second latching member with the main body. The rotary member, pivotally connected to the main body, connects the rod with the first latching member. The first and second latching members may close or separate from each other by applying a force to the movable member or the rod, so as to join with or release from the movable member.
While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. On the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation to encompass all such modifications and similar arrangements.
