Detailed Description

Referring to fig. 1 to 3, an embodiment of a rotating shaft 100 of the present utility model is suitable for being applied to an electronic device 200, and the electronic device 200 is, for example, a notebook computer, but not limited to this. The electronic device 200 has a first housing 201 and a second housing (not shown), wherein the first housing 201 may be provided with a keyboard, a screen, and a touch area (not shown), for example, and the rotating shaft 100 is connected between the first housing 201 and the second housing, so that the second housing can be opened and closed relative to the first housing 201. The rotating shaft 100 includes a base 1, a rotating member 2, a sliding member 3, a lifting support member 4, and a connecting rod set 5.

Referring to fig. 1 to 4, the base 1 is adapted to be disposed in the first housing 201. The base 1 includes a first seat 11 disposed at a rear side of the first housing 201, a second seat 12 disposed at the first seat 11, and a rotation shaft 13 disposed at a rear side of the first seat 11 in a front-rear direction D1 (arrow is directed forward, reverse is directed backward) and extending in a left-right direction D2 (arrow is directed right, reverse is directed left). The first seat 11 has a guide column 111 extending in the left-right direction D2, and a setting plate 112 extending upward from the front side in an up-down direction D3 (arrow upward, reverse downward) and having a plate surface facing forward. The second seat 12 is disposed at the end of the guide post 111 of the first seat 11, and the second seat 12 has an extension 121 extending forward.

Referring to fig. 2 to 5, the rotating member 2 is disposed on a rotating shaft 13 of the base 1 and is adapted to be disposed on the second housing, and the rotating member 2 can rotate relative to the base 1 about a rotating shaft A1 parallel to the left-right direction D2 between a first position (see fig. 2) and a second position (see fig. 8), wherein the rotating shaft A1 is an axis of the rotating shaft 13. The rotating member 2 has a rotating shaft sleeve 21 rotatably sleeved on the rotating shaft post 13, an arc convex surface 22 located on the rotating shaft sleeve 21, a first guiding portion 23 formed in a groove structure on the arc convex surface 22 of the rotating shaft sleeve 21 and extending obliquely around the rotating shaft A1, and a setting frame 24 extending from the rotating shaft sleeve 21 and provided for the second housing.

Referring to fig. 2 and 4 to 6, the sliding member 3 is disposed on the guiding post 111 of the base 1 and can slide along the left-right direction D2 relative to the guiding post 111 of the base 1, and the sliding member 3 has a sliding sleeve 31 slidably disposed on the guiding post 111 along the left-right direction D2, a circular arc concave surface 32 disposed at the rear side of the sliding sleeve 31 and matched with the circular arc convex surface 22, a first sliding portion 33 formed in the circular arc concave surface 32 in a bump structure and slidably connected to the first guiding portion 23 along the first guiding portion 23, and a second guiding portion 34 formed in the front side of the circular arc concave surface 32 in a groove structure and extending along the up-down direction D3.

Referring to fig. 1, 2, 4 and 5, the lifting support 4 is rod-shaped and is pivoted to the extension 121 of the second base 12 of the base 1, and the lifting support 4 can pivot between an initial position (see fig. 2) and a raised position (see fig. 8) below the initial position relative to the second base 12 of the base 1 about a pivot axis A2, wherein the pivot axis A2 is parallel to the front-rear direction D1. The lifting support 4 has a fixed end 41 pivoted to the base 1, and a support end 42 opposite to the fixed end 41, wherein the bottom of the support end 42 is used for providing a foot pad 300. Wherein the foot pad 300 provided to the support end 42 is located at the rear side of the first housing 201 and protrudes downward from the bottom of the first housing 201 through the first housing 201.

Referring to fig. 2 and 4-6, the linkage 5 includes a first rod 51 pivotally connected to the setting plate 112 of the base 1, a second rod 52 located below the first rod 51 and pivotally connected between the first rod 51 and the supporting end 42 of the lifting support 4, and a pivot 53 extending in the front-rear direction D1 and passing through a pivot of the first rod 51 and the second rod 52. The pivot 53 has a second sliding portion 531 with a bump structure and slidably connected to the second guiding portion 34 along the second guiding portion 34. The linkage 5 is capable of being shifted between a collapsed state (see fig. 2) in which the angle between the first rod 51 and the second rod 52 is relatively small, and an expanded state (see fig. 8) in which the angle between the first rod 51 and the second rod 52 is relatively large.

Referring to fig. 1 to 3, when the rotating member 2 is at the first position, the second housing is closed with respect to the first housing 201. The link set 5 is in the retracted state in which the angle between the first rod 51 and the second rod 52 is relatively small. The lifting support 4 is in the initial position. At this time, the downward protruding amount of the foot pad 300 on the lifting support 4 with respect to the first housing 201 may be uniform with other foot pads (not shown) at the front side of the first housing 201.

Referring to fig. 7 to 8, when the rotary member 2 rotates to the second position, the second housing is opened with respect to the first housing 201. The sliding member 3 is driven to slide along the left-right direction D2 (sliding to the left in the drawing), so as to link the linkage 5 to be converted into the unfolded state in which the included angle between the first rod member 51 and the second rod member 52 is relatively large, and the second rod member 52 of the linkage 5 links the lifting support member 4 to pivot downward to the raised position. At this time, the foot pad 300 on the lifting support 4 is more protruded downward with respect to the first housing 201 than other foot pads (not shown) at the front side of the first housing 201, and thus is supported higher at the rear side of the first housing 201 than at the front side. Thereby increasing the heat dissipation space of the electronic device 200 (notebook computer) and increasing the comfort of using the keyboard on the first housing 201 of the electronic device 200.

Subsequently, when the rotating member 2 rotates back to the first position, the second housing is covered again with respect to the first housing 201, and the lifting support member 4 is also interlocked back to the initial position, which is not described herein again. When the rotating member 2 is at the first position and the second housing is closed with respect to the first housing 201, the foot pad 300 on the lifting support 4 is less protruded with respect to the first housing 201, so that the electronic device 200 can be conveniently stored when not in use.

In addition, it should be noted that the present utility model may be applied to other embodiments (not shown) of the double-axis type, in addition to the embodiment of the single-axis type. In other embodiments of the double shaft form, the rotating member serves as a base, and a further rotating member adapted for the second housing is further provided on the rotating member (base).

In summary, the lifting support 4 in the rotating shaft 100 of the present utility model can be linked with the rotating member 2 through the sliding member 3 and the linkage 5, and when the rotating member 2 rotates from the first position to the second position, the lifting support 4 can be linked to pivot downward from the initial position to the raised position. Therefore, when the rotating shaft 100 is applied to the electronic device 200 such as a notebook computer, the lifting support 4 or the foot pad 300 provided on the lifting support 4 can be used to conveniently raise the rear side of the notebook computer when the notebook computer is used. Thereby increasing the heat dissipation space of the electronic device 200 (notebook computer) and increasing the comfort when using the keyboard on the first housing 201 of the electronic device 200.

The foregoing is merely illustrative of the present utility model and is not intended to limit the scope of the utility model, which is defined by the appended claims and their equivalents.
