In the following, the technical means adopted by the present invention to achieve the intended purpose of the present invention will be further explained in conjunction with the drawings and preferred embodiments of the present invention.

Please refer to FIG. 1 and FIG. 2. The first embodiment of the hinge assembly of the present invention is used to connect to a flip-type electronic device, such as a notebook computer. The flip-type electronic device has a base 40. And an upper cover 50, the hinge assembly includes a hinge 10, a speaker 20 and a reflecting plate 30.

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 piece 13, a hinge guide 14, a reflection guide 15 and一连 动 件 16。 A linkage 16.

The base connecting frame 11 is a frame body for connecting the base 40, and the upper cover connecting frame 12 is a frame body for connecting the upper cover 50.

The pivot piece 13 has two pivot shafts 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 piece The two pivot shafts 131 of 13 are arranged in parallel with each other, and the pivot piece 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 50 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 40 and the base connecting frame 11. Therefore, when the upper cover 50 is rotated 180 degrees relative to the base 40, the upper cover 50 is rotated 90 degrees relative to the housing 132, and the housing 132 Rotate 90 degrees relative to the base 40. With this design, the upper cover 50 can be rotated 360 degrees relative to the base 40.

The pivot guide 14 is fixed on the pivot 13 in the axial direction of the pivot 10, and when the base connecting frame 11 and the upper cover connecting frame 12 pivot relative to each other, the pivot guide 14 will rotate together; in this implementation In the example, the pivot guide 14 is relatively rotatably sleeved on the pivot 131 corresponding to the base connecting frame 11, and the pivot guide 14 is fixed on the housing 132 of the pivot 13 to thereby serve as the upper cover. When 50 is rotated at a specific angle relative to the base 40, the housing 132 drives the pivot guide 14 to rotate by half the angle.

However, the hinge member 13 is not limited to the above-mentioned structure. The hinge member 13 can also be a general structure of a hinge device, that is, two pivot shafts are connected coaxially, which can still achieve the purpose of rotating the upper cover 50 relative to the base 40. At this time, the hinge The guide member 14 is instead fixed on a pivot shaft 131 corresponding to the upper cover connecting frame 12, so that when the upper cover 50 rotates a specific angle with respect to the base 40, the pivot shaft 131 drives the pivot guide member 14 to rotate the same Angle.

The reflection guide 15 is used for connecting and rotating the reflection plate 30, and the reflection guide 15 is disposed along the axial direction of the hinge 10.

The linking member 16 connects the pivot guide 14 and the reflection guide 15, and when the pivot guide 14 rotates relative to the linking member 16, the linking member 16 selectively rotates the reflection guide 15;

Please refer to FIGS. 3 to 6. In this embodiment, the pivot guide 14 and the reflection guide 15 are both cylindrical, and a first guide is recessed around the outer wall surface of the pivot guide 14. A track 141 and a second guide track 151 are recessed around the outer wall surface of the reflection guide 15. The track of the second guide track 151 and the track of the first guide track 141 are different; the link 16 can only move in a straight line. Cannot rotate, a first guide post 161 and a second guide post 162 protrude from the linking member 16, the first guide post 161 runs through the first guide track 141, and the second guide post 162 runs through the first Two guide rails 151;

Thereby, when the pivot guide 14 rotates relative to the link 16 to the wall surface of the first guide rail 141 and pushes against the first guide post 161, the pivot guide 14 pushes the link 16 and then moves relative to the reflection guide 15 The second guide post 162 of the link 16 pushes against the wall surface of the second guide track 151 to rotate the reflection guide 15; in other words, the rotation of the pivot guide 14 is converted into the movement of the link 16 and the link The movement of the piece 16 is then converted into the rotation of the reflection guide 15, and because the trajectory of the second guide track 151 and the trajectory of the first guide track 141 are different, the rotation mode of the pivot guide 14 and the reflection guide are made different. The rotation pattern of the piece 15 is different.

In this embodiment, when the pivot guide 14 rotates relative to the link 16 and the link 16 rotates the reflection guide 15, the direction in which the pivot guide 14 rotates relative to the link 16 and the link 16 rotate the reflection guide 15 is in the opposite direction; in other words, when the upper cover 50 is pivoted rearwardly relative to the base 40, the linkage 16 rotates the reflection guide 15 and the reflection plate 30 forward (as shown in FIGS. 9 and 14); but Not limited to this, the direction in which the pivot guide 14 is rotated relative to the linkage 16 may be the same as the direction in which the linkage 16 rotates the reflection guide 15 according to requirements.

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 90 degrees, 60 degrees, and 30 degrees, in other words, from a cross section perpendicular to the axial direction L of the pivot guide 14 (the cross section uses the axial center direction L as a normal line) From the perspective (as shown in Figs. 19 and 20), the angle occupied by the starting straight segment 1411 is 90 degrees. From the perspective of the action, the pivot guide 14 is rotated by 90 degrees (in this embodiment, it is equivalent to the upper cover 50). 180 degrees relative to the base 40), it can move from one end of the starting straight segment 1411 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 an inclination with respect to both end faces A of the reflection guide 15, but in this embodiment, the second guide The oblique direction of the oblique section 1511 of the track 151 is different from the oblique direction of the oblique section 1412 of the first guide track 141, so as to achieve the direction in which the pivot guide 14 is rotated relative to the linkage 16 and the reflection guidance of the linkage 16 is rotated. In the present embodiment, the corresponding angle of the oblique section 1511 on the cross section of the axial direction of the vertical cylindrical reflection guide 15 is 180 degrees. The reflection guide 15 can be rotated 180 degrees to move from one end of the oblique section 1511 to the other end (as shown in FIGS. 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 reflection guide 15). The distance D2 of the oblique section 1511 in the axis direction of the cylindrical reflection 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 diagonal section 1511 of 151 moves to the other end;

Regardless of the oblique directions of the two oblique sections 1412 and 1511 being opposite, and only looking at the angle between the two oblique sections 1412 and 1511 and their respective end faces A, since the oblique section 1511 of the second guide track 151 is vertical The corresponding angle (180 degrees) on the cross section in the axial direction is larger than the corresponding angle (60 degrees) on the cross section of the oblique section 1412 of the first guide track 141 in the vertical axial direction. Therefore, when the pivot guide 14 After the linking member 16 is pushed by rotating 60 degrees, the linking member 16 causes the reflection guide 15 to rotate 180 degrees in the reverse direction.

The aforementioned speaker 20 is located at one end of the hinge device 10 along the axial direction of the hinge device 10, and the speaker 20 has a sound hole 21; in this embodiment, the speaker 20 has a long shape, and specifically a cylindrical shape. The sound emitting hole 21 of 20 is located on a side of the speaker 20 that is perpendicular to the extending direction of the speaker 20, but is not limited to this. The shape of the speaker 20 and the position of the sound emitting hole 21 can also be changed as long as it can cooperate with the reflection plate 30. The sound of the sound emitting hole 21 may be reflected by the reflection plate 30.

The aforementioned reflection plate 30 surrounds the speaker 20 and is fixed to the reflection guide 15 along the axial direction of the hinge 10 to rotate around the speaker 20 as the reflection guide 15 rotates. The reflection plate 30 is selectively rotated to Facing the sound output hole 21 of the speaker 20; in this embodiment, the reflection plate 30 is long and includes two end plates 31 and a ring wall 32; the two end plates 31 are respectively located at two ends of the speaker 20, and one end thereof The reflection guide 15 is fixed on the plate 31, and the reflection guide 15 is coaxial with the cylindrical speaker 20; the ring wall 32 is connected between the two end plates 31 and can be rotated to the sound output hole 21 facing the speaker 20 In this embodiment, the corresponding angle of the ring wall 32 on the cross section of the vertical reflecting plate 30 extending direction is between 75 degrees and 105 degrees, and preferably 90 degrees, but it is not limited to this, and may be The other angles only need to be matched with the angle of the oblique section 1511 of the second guide track 151, and the sound can be reflected to the sound output hole 21 of the speaker 20 after being rotated behind the set angle.

When the foregoing embodiment of the present invention is used, please first refer to FIG. 7 and FIG. 12. When the upper cover 50 is closed with respect to the base 40 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 segment 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 reflection guide 15. At this time, the sound output hole 21 of the speaker 20 Directly above, and the reflection plate 30 is located at the rear of the speaker 20 obliquely downward, so the sound of the speaker 20 will be emitted directly upward, and the reflection plate 30 is not reflecting at this time;

Please refer to FIG. 8 and FIG. 13, and then lift the upper cover 50 relative to the base 40 by 180 degrees. At this time, the housing 132 and the pivot guide 14 are only rotated 90 degrees, and the first guide post 161 has been relatively moved to the start. The other end of the straight segment 1411, but at this time it can be said that it is idling without moving the linkage 16, so the second guide post 162 and the reflection guide 15 have not yet taken any action, and therefore the cover 50 is lifted to 180. During this period, the position of the reflection plate 30 has not changed, and the sound of the speaker 20 continues to be emitted upward, thereby under the general use situation of the flip-type electronic device (without the flip-up to 180 degrees) , The sound output hole 21 and the sound emitted by the speaker 20 are still substantially directed toward the user.

Please refer to FIG. 9 and FIG. 14, and then further lift the upper cover 50 relative to the base 40. Since the first guide post 161 moves obliquely along the oblique section 1412, the link 16 starts to move laterally, and then passes through the second guide The guide post 162 drives the reflection guide 15 to start to rotate in the reverse direction, so the reflection plate 30 also starts to rotate in the reverse direction and gradually approaches the sound output hole 21 of the speaker 20;

Please refer to FIG. 10 and FIG. 15, and then continue to rotate the upper cover 50 relative to the base 40 until 300 degrees, the first guide post 161 has been relatively moved to the other end of the oblique section 1412, and the second guide post 162 has also been relatively Move the other end of the oblique section 1511, and make the reflection guide 15 and the reflection plate 30 reversely rotate to 180 degrees, and face a part of the sound output hole 21 of the speaker 20. At this time, the upper cover 50 and the base 40 are opposite to each other. It is pivoted to a tent-type use mode, and is rotated forward to the reflection plate 30 outside the sound output hole 21, and its position can reflect the sound of the sound output hole 21 obliquely toward the pivot side of the upper cover 50. At this time, if the base 40 and the upper cover 50 are erected in an A shape, the reflected sound will be directed obliquely upward toward the user in front of the screen.

Please refer to FIG. 11 and FIG. 16. Finally, continue to rotate the upper cover 50 relative to the base 40 until 360 degrees. At this time, the upper cover 50 and the base 40 are parallel to each other, and the first guide post 161 is moved from the end of the end straight section 1413 to At the other end, this period can be said to be idling, and the linkage 16 has not moved during this period. Therefore, the second guide post 162 and the reflection guide 15 have no further action.

According to the present invention, the rotation of the upper cover 50 relative to the base 40 can be used to rotate the reflection plate 30 according to a specific relationship, so that the reflection plate 30 can be rotated to a specific angle and position to reflect the sound of the sound output hole 21 of the speaker 20, By keeping the reflected sound towards the user, the invention achieves its purpose.

In addition, the first guide track 141 and the second guide track 151 are not limited to the above-mentioned trajectory and angle, and can be changed and adjusted according to requirements as long as the rotation of the upper cover 50 relative to the base 40 can be in accordance with a specific relationship. Just turn the reflection plate 30.

The ring flanges are respectively arranged in the two grooves of the linking member 16 and pass through the specific trajectory shape of each ring flange so that when the pivot guide 14 rotates, the linking member 16 can be caused to move linearly, and the linking of the linear movement The member 16 rotates the reflection guide 15 again, so that the same object of the invention can be achieved.

3, 4, 17, and 18, regarding the structure that moves the link 16 linearly, in this embodiment, the base connecting frame 11 is provided with two first limiting portions 111, The linking member 16 is provided with two second limiting portions 163, and the two first limiting portions 111 cooperate with the two second limiting portions 163, respectively, so that the linking member 16 can only be opposed to the pivot guide 14 and The reflection guide 15 moves back and forth on a straight line;

Furthermore, each of the first limiting portions 111 of the base connecting frame 11 is a convex post, and each of the second limiting portions 163 of the link 16 is a long groove, and the first limiting portions 111 pass through the second In the limiting portion 163, the purpose of limiting linear movement is achieved; however, the structure of the first limiting portion 111 and the second limiting portion 163 is not limited to this. For example, the first limiting portion 111 may be changed to a long one. Each of the second limiting portions 163 of the linkage 16 is a convex column, which can also achieve the purpose of limiting linear movement; in addition, the number of the first limiting portions 111 and the second limiting portions 163 can be only one In this way, the purpose of limiting linear motion can also be achieved.

In addition, the linking member 16 can also limit its linear movement in other ways. For example, it can be matched with other elements other than the base connecting frame 11, such as other elements on the base 40 to limit the linear movement of the linking member 16.

Finally, the linking member 16 may also link the pivot guide 14 and the reflection guide 15 instead of moving in a straight line. In short, the linking member 16 can be selectively selected when the pivot guide 14 rotates relative to the linking member 16. It is sufficient to turn the reflection guide 15 by ground.
