Fig. 1 is an exploded view showing an electronic device according to an embodiment of the present invention. The electronic device mainly includes a first module 10, a second module 20, a pivot 30, a stopper 40, and an elastic member 50. The first module 10 has an upper cover 11 and a lower cover 12. And the upper cover 11 has a hole 11A. Referring to the first and second figures, the pivot 30 is fixed on the second module 20 and pivoted to the first module 10, and the stopper 40 is slidably disposed on the first module 10, and the elastic The component 50 connects the stopper 40 and the first module 10. The first module 10 is, for example, an input module, and the second module 20 is, for example, a display module.

Referring to FIGS. 1 and 2 together, the stopper 40 of the embodiment has an arc-shaped recess 41, a protrusion 42 and a curved surface 43, and the upper cover 11 has a receiving portion 11B. The shaft 30 is housed in the recessed portion 41 and the accommodating portion 11B. The protruding portion 42 passes through the hole 11A of the upper cover 11. The pivot 30, the elastic member 50 and the stopper 40 are all covered by the upper cover 11 and are hidden in the first module 10.

Referring to Figures 3A and 3B, the pivot 30 has a rib. 31, when the stopper 40 is at a first position, and the second module 20 is rotated relative to the first module 10 to a first angle (as shown in FIG. 3A), the rib 31 abuts the curved surface 43 Thereby, the second module 20 is limited to the first angle (as shown in FIG. 3B). Referring to FIGS. 4A and 4B , when it is required to further rotate the second module 20 relative to the first module 10 to a second angle, the protrusion 42 can be pushed to make the stopper 40 relative to the first A module 10 is displaced from the first position along a first direction (as indicated by the direction of the arrow in FIG. 4A) to a second position. At this time, the rib 31 can be separated from the curved surface 43, thereby enabling the second module 20 to be Rotating from the first angle to the second angle relative to the first module 10 (as shown in FIG. 4B). It should be understood that when the second module 20 is rotated back to the first angle with respect to the first module 10 by the second angle, the elastic member 50 can provide a spring force in the second direction (as indicated by the arrow direction in FIG. 2). Shown that the stop 40 is automatically reverted from the aforementioned second position to the first position. Wherein, the first direction is substantially parallel to the central axis C of the pivot axis 30, and the second direction is opposite to the first direction, and the curved surface 43 can be, for example, one such that the rib 31 can abut the curved surface 43 at various angles. Hyperboloids. In this embodiment, the first angle is less than or equal to 90°, and the second angle is between 90° and 135°.

Referring to FIGS. 5A and 5B, an electronic device according to another embodiment of the present invention replaces the rib 31 on the pivot 30 with a gear 60 and a gear bar 70. In the present embodiment, the gear 60 is fixed to the pivot 30, and the gear bar 70 is movably disposed on the lower cover 12 and the gear 60. In addition, the stopper 40 has a first inclined surface 44, and the gear bar 70 has a second inclined surface 71, wherein the first inclined surface 44 corresponds to the second inclined surface 71. When the stopping member 40 is in a first position and the second module 20 is rotated to the first angle relative to the first module 10, the gear 60 drives the gear bar 70 to move downward relative to the first module 10, so that The second inclined surface 71 abuts the first inclined surface 44, thereby The second module 20 is limited to be at the first angle. When it is required to further rotate the second module 20 relative to the first module 10 to a second angle, the protrusion 42 can be pushed (as indicated by the direction of the arrow in FIG. 5B), so that the stopper 40 is opposite to the block 40 The first module 10 is displaced from the first position to the second position by the first position. The second inclined surface 71 is separated from the first inclined surface 44, so that the second module 20 can be rotated relative to the first module 10. To the second angle. Conversely, when the second module 20 is returned to the first angle from the second angle relative to the first module 10, the elastic member 50 can provide a spring force in a second direction (as indicated by the direction of the arrow in FIG. 5A), so that The stop 40 is automatically reverted from the aforementioned second position to the first position. The first direction is substantially parallel to the central axis C of the pivot 30, and the second direction is opposite to the first direction. In another embodiment, the first inclined surface 44 may also be formed with a stepped structure.

In summary, the present invention provides an electronic device having a slidable stopper, by which the second module can be restricted at a desired angle without causing the second module to be opposed by an external force. The first module rotates, and the second module will not suffer from resistance when it is returned to the closed angle with respect to the first module. In addition, since the stopper is not in contact with the rib or the gear bar when the second module is rotated, the wear of the mechanism for limiting the angle of the second module can be reduced, and the service life of the electronic device is increased.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. Those skilled in the art having the ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
