[0026] Referring to Figures 1 to 4 The embodiment of the present application pivot 100, suitable for application in an electronic device (not shown), the electronic device is exemplified as a notebook computer, but not limited thereto. The electronic device has a first housing (not shown), and a second housing (not shown), the first housing can be provided with a keyboard, touch area (not shown), for example, the second housing can be provided with a screen (not shown), for example, the pivot 100 is connected between the first housing and the second housing, so that the second housing can be relative to the first housing open. The pivot 100 comprises a base 1, a swing rod 2, a rotating member 3, and a locking unit 4.
[0027] Referring to Figures 1 to 4, the base 1 is adapted to be disposed at a rear side of the first housing in a front-rear direction D1 (arrow pointing forward and reverse pointing rearward). The base 1 has a first seat body 11 and a second seat body 12 arranged in a left-right direction D2 (lateral direction, arrow pointing right and reverse pointing left), a spacer sheet 13 interposed between the first seat body 11 and the second seat body 12, a first recessed rail 14 and a second recessed rail 15 respectively formed in the first seat body 11 and the second seat body 12 recessed in the left-right direction D2, and a pivot shaft portion 16 extending along a first rotation axis A1 parallel to the left-right direction D2 and provided to the first seat body 11, the second seat body 12, and the spacer sheet. The spacer sheet 13 interposed between the first seat body 11 and the second seat body 12 spaces the first recessed rail 14 and the second recessed rail 15 from each other in the left-right direction D2. The first recessed rail 14 is in a circular arc shape. The second recessed rail 15 has a guide rail portion 151, and an arc-shaped rail portion 152 open at one end and connected to the guide rail portion 151 at the other end and in a circular arc shape. In the present embodiment, the guide rail portion 151 is straight and tangent to the arc-shaped rail portion 152, but in other embodiments, the guide rail portion 151 can be adjusted in structure as needed without being straight, not limited to the present embodiment.
[0028] The swing lever 2 is provided to the base 1. The swing lever 2 is rotatable relative to the base 1 about the first rotation axis A1 between an initial position and a lowered position. The swing lever 2 has a first end portion 21 provided to the pivot shaft portion 16 and located forward, a second end portion 22 opposite to the first end portion 21 and located rearward, and a sliding rail 23 formed recessed in the left-right direction D2 and located between the first end portion 21 and the second end portion 22. The sliding rail 23 extends substantially along the length direction of the swing lever 2. In the initial position, the second end portion 22 is located higher in an up-down direction D3 (arrow pointing upward and reverse pointing downward); in the lowered position, the second end portion 22 is located lower in the up-down direction D3.
[0029] The rotating member 3 is arranged on the swing rod 2, and specifically, the rotating member 3 is rotatably arranged on the second end 22 of the swing rod 2. The rotating member 3 is rotatable relative to the swing rod 2 about a second rotation axis A2 parallel to the left-right direction D2 between a first position and a second position, and passes through a transition position during rotation between the first position and the second position. The rotating member 3 includes a rotation axis body 31 rotatably arranged on the swing rod 2, and a connecting frame body 32 arranged on the rotation axis body 31 and provided with the second housing. The rotation axis body 31 has a first sliding portion 311 arranged in the first recess track 14 and located on the second rotation axis A2, and a second sliding portion 312 which is slidable along the second recess track 15. The distance between the center of the second sliding portion 312 and the second rotation axis A2 is equal to the radius of curvature of the arc-shaped track portion 152.
[0030] The locking unit 4 is arranged on the rotating member 3 and moves together with the rotating member 3. The locking unit 4 is switchable between a locked state for limiting the position of the swing rod 2 in the initial position and an unlocked state for not limiting the position of the swing rod 2. The locking unit 4 has a linkage member 41 arranged on the rotating member 3 and rotating synchronously with the rotating member 3, a fixed member 42 integrally arranged on the fixed pivot portion 16 of the base 1 and fixedly arranged on the base 1, and a sliding member 43 arranged on the swing rod 2 and located between the linkage member 41 and the fixed member 42. The linkage member 41, the fixed member 42 and the sliding member 43 are accommodated in a receiving space defined between the base 1 and the swing rod 2. The linkage member 41 has a first recess portion 411, and the fixed member 42 has a second recess portion 421. The sliding member 43 has a sliding protrusion 431 which is slidably arranged on the sliding track 23, so that the sliding member 43 is slidable relative to the swing rod 2 between the linkage member 41 and the fixed member 42, and is partially accommodated in the first recess portion 411 or / and the second recess portion 421.
[0031] In addition, in the present embodiment, a torsion module 5 which rotates synchronously with the rotation axis body 31 of the rotating member 3 is additionally arranged on the rotation axis body 31 of the rotating member 3. The torsion module 5 is used to generate friction between the swing rod 2 and the rotating member 3 to resist the rotation of the rotation axis body 31 of the rotating member 3, so that the electronic device can be positioned at each opening angle, and the operation feeling of the user when opening and closing the electronic device is improved.
[0032] Referring to Figure 5 and Figure 6When the rotating member 3 is at the first position, the second housing is closed relative to the first housing. The first recess 411 of the linkage member 41 faces away from the sliding member 43, the sliding member 43 is unable to slide and is partially accommodated in the second recess 421 of the fixed member 42, and the locking unit 4 is in the locked state. At this time, the sliding member 43 is limited by the second recess 421 and is unable to move downward, and in turn the swing lever 2 is unable to rotate relative to the base 1 and is locked in the initial position. At this stage, the second sliding portion 312 has not yet entered the second recess track 15 and is outside the second recess track 15.
[0033] Referring to Figure 7 and Figure 8 When the rotating member 3 is rotated from the first position to the transition position, the second housing is opened by about 90 degrees relative to the first housing, the locking unit 4 is still in the locked state, and the swing lever 2 is still unable to rotate relative to the base 1 and is locked in the initial position. At this stage, the second sliding portion 312 enters the arc-shaped track portion 152 of the second recess track 15.
[0034] Referring to Figure 9 and Figure 10 When the rotating member 3 continues to rotate to the transition position, the second housing is opened by about 120 degrees relative to the first housing. The first recess 411 of the linkage member 41 faces the sliding member 43, the sliding member 43 can slide between the linkage member 41 and the fixed member 42 to be partially accommodated in the first recess 411 or / and the second recess 421, and the locking unit 4 is linked by the rotating member 3 and is switched to the unlocked state. At this time, the sliding member 43 is not limited by the second recess 421 and can move downward, and in turn the swing lever 2 is not locked in the initial position and can rotate relative to the base 1. However, at this time, the swing lever 2 is still in the initial position. At this stage, the second sliding portion 312 passes through the arc-shaped track portion 152 to the junction of the arc-shaped track portion 152 and the guide track portion 151.
[0035] In the above-mentioned process of rotating the rotating member 3 from the first position to the transition position, the swing lever 2 is limited in the initial position by the locking unit 4, and the second rotation axis A2 around which the rotating member 3 rotates is located at a higher position. In this way, the second housing provided on the rotating member 3 can also be located at a higher position to upwardly avoid the heat dissipation air outlet provided on the lower part of the rear side of the first housing of the electronic device.
[0036] Referring to Figure 11 and Figure 12When the rotating member 3 rotates from the transition position to the second position, and the second housing is opened about 150 degrees relative to the first housing, the locking unit 4 is still in the unlocked state, and the swing lever 2 is between the initial position and the lower swing position, so that the position of the second rotation axis A2 is slightly lowered. At this stage, the second sliding part 312 slides to the end of the guide rail part 151.
[0037] Referring to Figure 13 and Figure 14 When the rotating member 3 continues to rotate to the second position, and the second housing is opened about 180 degrees relative to the first housing, the locking unit 4 is still in the unlocked state, and the swing lever 2 is in the lower swing position, so that the position of the second rotation axis A2 is lowered to the lowest point. At this stage, the second sliding part 312 continues to slide in the guide rail part 151 of the second recessed rail 15.
[0038] It should be noted that, during the process of rotating the rotating member 3 from the transition position to the second position, although the locking unit 4 is in the unlocked state, the position of the swing lever 2 is not limited by the locking of the locking unit 4, but the cooperation between the second sliding part 312 and the guide rail part 151 of the second recessed rail 15 limits the position of the first sliding part 311 (the second rotation axis A2), so that the swing lever 2 cannot rotate and swing arbitrarily. That is, although the position of the swing lever 2 is not limited by the locking of the locking unit 4 during the above process, the position of the swing lever 2 and the first sliding part 311 is still determined by the position (rotation angle) of the rotating member 3, and will not be moved arbitrarily to have a loose operation feeling.
[0039] During the process of rotating the rotating member 3 from the transition position to the second position, the swing lever 2 can be rotated to the lower swing position by the cooperation between the second sliding part 312 and the guide rail part 151 of the second recessed rail 15, so that the second rotation axis A2 around which the rotating member 3 rotates is moved to a lower position. In this way, the second housing provided on the rotating member 3 can also be located at a lower position to avoid the heat dissipation air outlet provided on the lower part of the rear side of the first housing of the electronic device.
[0040] In summary, in the process that the rotating member 3 rotates from the first position to the transition position, the locking unit 4 limits the swing lever 2 at the initial position, so that the second rotation axis A2 around which the rotating member 3 rotates is located at a higher position; and in the process that the rotating member 3 rotates from the transition position to the second position, the cooperation between the second sliding part 312 and the guide rail part 151 of the second concave rail 15 enables the swing lever 2 to rotate to the lower swing position, and then enables the second rotation axis A2 around which the rotating member 3 rotates to move to a lower position. In this way, in the process that the electronic device using the rotating shaft 100 is opened and closed, the second shell of the electronic device can avoid the heat dissipation air outlet of the first shell of the electronic device at most of the commonly used angles, so as to avoid affecting the heat dissipation performance of the electronic device.
[0041] The above is only an embodiment of the present application, and cannot limit the scope of the present application. Any simple equivalent change and modification made according to the claims and the specification of the present application still belongs to the scope of the present application.
