Please refer to FIG. 1, FIG. 3 and FIG. 4. The aforementioned hinge device 10 includes a base connecting frame 11, an upper cover connecting frame 12, a hinge assembly 13, a pivot guide 14, a horn guide 15 and一连 动 件 16。 A linkage 16.

The base connecting frame 11 is used to connect the base 30, and the upper cover connecting frame 12 is used to connect the upper cover 40.

The pivot assembly 13 has two pivots 131, which are respectively connected to the base connecting frame 11 and the upper cover connecting frame 12, so that the base connecting frame 11 and the upper cover connecting frame 12 can be relatively pivoted; in this embodiment, the pivot assembly The two pivot shafts 131 of 13 are arranged in parallel with each other, and the pivot assembly 13 further includes a housing 132, and the two pivot shafts 131 are rotatably disposed in the housing 132 relative to the housing 132; in other words, the upper cover 40 and the upper cover connecting frame 12 may be Rotate relative to the housing 132, and the housing 132 can rotate relative to the base 30 and the base connecting frame 11. Therefore, when the upper cover 40 rotates 180 degrees relative to the base 30, the upper cover 40 rotates relative to the housing 132 90 degrees, and the housing 132 rotates 90 degrees with respect to the base 30. With this design, the upper cover 40 can be rotated 360 degrees with respect to the base 30.

The pivot guide 14 is disposed on the pivot assembly 13, and when the base connecting frame 11 and the upper cover connecting frame 12 pivot relative to each other, the pivot guide 14 is rotated together; in this embodiment, the pivot guide 14 may Relatively sleeved on the pivot shaft 131 corresponding to the base connecting frame 11, and the pivot guide 14 is fixed on the housing 132 of the pivot assembly 13, so that when the upper cover 40 rotates a specific angle relative to the base 30 At this time, the housing 132 drives the pivot guide 14 to rotate by half an angle.

However, the hinge assembly 13 is not limited to the above structure. The hinge assembly 13 can also be a general hinge structure, that is, two pivots are coaxially connected, and it can still achieve the purpose of rotating the upper cover 40 relative to the base 30. The guide member 14 is instead fixed on a pivot 131 corresponding to the upper cover connecting frame 12, so that when the upper cover 40 rotates a specific angle with respect to the base 30, the pivot 131 drives the pivot guide 14 to rotate the same Angle.

The horn guide 15 is used to connect and rotate the horn 20, and the horn 20 is fixed to the horn guide 15 along the axial direction of the hinge device 10. In this embodiment, the horn 20 is a long bar, and is specifically a cylinder That is, the sound emitting hole 21 of the horn 20 is located on a side of the horn 20 in a direction perpendicular to the extending direction of the horn 20, and the horn guide 15 is fixed to one end of the long horn 20, but not limited to this The speaker 20 may also have other shapes, such as a rectangular parallelepiped, etc., or not even a long shape, as long as it can be located at the pivot axis of the flip-type electronic device and can be rotated by the speaker guide 15.

The linking member 16 connects the pivot guide 14 and the horn guide 15, and when the pivot guide 14 rotates relative to the linking member 16, the linking member 16 selectively rotates the horn guide 15; see FIGS. 3 to 6 As shown, in this embodiment, the pivot guide 14 and the horn guide 15 are both cylindrical, and a first guide track 141 is recessed around the outer wall surface of the pivot guide 14 and the horn guide A second guide track 151 is recessed around the outer wall surface of 15. The track of the second guide track 151 is different from the track of the first guide track 141; the link 16 can only move in a straight line and cannot turn A first guide post 161 and a second guide post 162 protrude from the linkage member 16. The first guide post 161 runs through the first guide track 141 and the second guide post 162 runs through the second Guide track 151; thereby, when the pivot guide 14 is rotated relative to the linkage 16, the wall surface of the first guide track 141 is selectively pushed against the first guide post 161 to be opposite to the pivot guide 14 and the horn The guide member 15 pushes the link member 16 together, and then the second guide post 162 of the link member 16 that moves relative to the horn guide member 15 selectively pushes against the wall surface of the second guide rail 151 to relatively rotate the horn guide In other words, the rotation of the pivot guide 14 is converted into the movement of the link 16, and the movement of the link 16 is converted into the rotation of the horn guide 15, and because of the trajectory of the second guide track 151 and The trajectories of the first guide track 141 are different, so that the rotation mode of the pivot guide 14 and the rotation mode of the horn guide 15 are different.

Specifically, the trajectory of the first guide track 141 sequentially includes a starting straight segment 1411, an oblique segment 1412, and an end straight segment 1413. The straight segment 1411, 1413, and oblique segment 1412 referred to herein are relative Parallel or inclined to the two end surfaces A of the pivot guide 14; in this embodiment, the starting straight segment 1411, the oblique segment 1412, and the end straight segment 1413 are in the direction of the axis of the vertically cylindrical pivot guide 14 The corresponding angles on the cross section are 75 degrees, 75 degrees, and 30 degrees, in other words, from a cross section perpendicular to the axis direction L of the pivot guide 14 (the cross section uses the axis direction L as a normal line) From the perspective (as shown in Figs. 19 and 20), the angle occupied by the oblique section 1412 is 75 degrees. From the perspective of the action, the pivot guide 14 is rotated 75 degrees (in this embodiment, it is equivalent to the upper cover 40 relative to each other). The base 30 is turned 150 degrees), and it can move from one end of the oblique section 1412 to the other end (as shown in FIGS. 13 and 15).

The trajectory of the second guide track 151 includes an oblique section 1511. The oblique section 1511 referred to here also refers to a slope with respect to the two end surfaces A of the horn guide 15; in this embodiment, the oblique section 1511 is at The corresponding angle on the cross section of the axial direction of the vertical cylindrical horn guide 15 is 120 degrees. From the point of view of the operation, if the horn guide 15 is rotated 120 degrees, it can be moved from one end of the oblique section 1511. To the other end (as shown in Figures 13 and 15).

5 and FIG. 6 (FIG. 5 is a plan development view of the outer wall surface of the pivot guide 14 and FIG. 6 is a plan development view of the outer wall surface of the horn guide 15). The distance D2 of the oblique section 1511 in the axis direction of the cylindrical horn guide 15 is equivalent to the oblique section 1412 of the first guide track 141 in the axis direction of the cylindrical pivot guide 14 In other words, the oblique section 1412 of the pivot guide 14 can push the link 16 through the first guide post 161, which can make the link 16 pass from the second guide track through the second guide post 162. One end of the oblique section 1511 of 151 moves to the other end; and because the corresponding angle (120 degrees) of the cross section of the oblique section 1511 of the second guide track 151 in the vertical axis direction is larger than the first guide track 141 The corresponding angle (75 degrees) of the oblique section 1412 in the cross section of the vertical axis direction, so when the pivot guide 14 is rotated 75 degrees to push the link 16, the link 16 will cause the horn guide 15 to rotate 120 degree.

When the foregoing embodiment of the present invention is used, please first refer to FIG. 7 and FIG. 12. When the upper cover 40 is closed with respect to the base 30 and parallel to each other, the first guide post 161 of the link 16 is located at the first of the pivot guide 14. One end of a starting straight section 1411 of a guide track 141, and the second guide post 162 is located at one end of the oblique section 1511 of the second guide track 151 of the horn guide 15. At this time, the sound output hole 21 of the horn 20 It is directed upwards; please refer to FIG. 8 and FIG. 13, and then lift the upper cover 40 relative to the base 30 by 150 degrees. At this time, the housing 132 and the pivot guide 14 are only rotated by 75 degrees, and the first guide post 161 is relatively opposed. Move to the other end of the initial straight segment 1411, but at this time it can be said that it is idling without moving the link 16, so the second guide post 162 and the horn guide 15 have not yet performed any action, and therefore are also on the upper cover. During the period from 40 to 150 degrees, the horn 20 still keeps the sound hole 21 facing directly upward, so that under normal use of the flip-type electronic device, the sound hole 21 of the horn 20 is generally facing the user.

Please refer to FIG. 9 and FIG. 14, and then further lift the upper cover 40 relative to the base 30. Since the first guide post 161 moves obliquely along the oblique section 1412, the link 16 starts to move laterally. The second guide post 162 drives the horn guide 15 to start rotating, so the horn 20 and the sound emitting hole 21 also start to rotate; please refer to FIG. 10 and FIG. 15, and then continue to rotate the upper cover 40 relative to the base 30 until 300 Degrees, the first guide post 161 has relatively moved the other end of the oblique section 1412, and the second guide post 162 has also relatively moved the other end of the oblique section 1511, and the horn guide 15 and the horn 20 have been rotated until 120 degrees; at this time, the upper cover 40 and the base 30 have been relatively pivoted to the tent-type use mode, and the speaker 20 after being rotated 120 degrees from the sound outlet hole 21 directly above, the sound outlet hole 21 is generally obliquely facing the upper cover The pivot side of 40 is set at this time. If the base 30 and the upper cover 40 are erected in an A shape at this time, the sound output hole 21 will be inclined upwardly toward the user in front of the screen.
