In other words, the reset movement is a movement from the state of FIG. 4A (the snapping element 136 is pressed to release the buckling state) to the state of FIG. 4F (the snapping element 136 is in the folded state). Since in the reset movement, the actuation mechanism of each element is reversed to the actuation mechanism of each element in the buckle movement, it will not be repeated here.

Although the buckle mechanism of the foregoing embodiment is applied to a notebook computer or an industrial notebook computer as an example, the case is not limited to this. The buckle mechanism 13 provided by each embodiment in this case utilizes a slider 134 to drive a multi-link assembly (a first link 131, a second link 132, a third link 133 or more links) and a buckle element 136 completes the buckling movement of one step of buckling the buckling element 136 provided in the second housing 12 with the concave portion 111 of the first housing 11; and when the buckling element 136 moves away from the concave portion 111, it will be caused by the return element 135 enables the slider 134 to drive the multi-link assembly and the buckle element 136 to complete a step of resetting. Therefore, the buckle mechanism 13 provided in this case is very simple whether it is buckle action or reset action.

The buckle mechanism 13 in this case uses the characteristics of the return element 135 and the necessary actions required for opening and closing (covering or uncovering the first housing 11 and the second housing 12) to complete a step of buckling movement Or one-step reset movement. In other words, in addition to covering the first housing 11 and the second housing 12, the user does not need additional actions to complete the buckle at the same time; and in addition to pressing the buckle element 136 (release the buckle Except for element 136), the action of releasing the closed state can be completed at the same time without additional action, so it is quite simple.

In summary, in the buckle mechanism of the present case, the first housing has a concave portion for buckling and a convex portion corresponding to the slider provided on the second housing. Thereby, when the first housing is covered with the second housing, the first housing presses the slider to make the slider press the restoring element, the linkage portion drives the first linkage, and the first linkage portion drives the second linkage , The second linkage portion and the third linkage portion drive the buckle element to rotate, so that the buckle element is buckled in the concave portion. With the connection relationship of the first linkage portion, the second linkage portion, and the third linkage portion, the buckle element in this case moves from the position where it does not protrude from the second housing to the position of the concave portion of the first housing in a curved motion track , And the buckle element is tightly buckled with the recess. At the same time, the convex part of the first housing is matched with the slider guide groove of the second housing.
