FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. FIG. 2 and FIG. 3 respectively illustrate schematic views of the electronic device in FIG. 1 in different states. Please refer to FIG. 1 to FIG. 3 at the same time. In this embodiment, the electronic device 100 is, for example, a notebook computer, which has a first body 110, a second body 120, an arm 130 and a shaft assembly 140, wherein the first body 110 is, for example, A display element of a notebook computer, especially a touch-sensitive display element, has a touch surface S1 and a back surface S2 opposite to each other, and a user can perform input and control through the touch surface S1.

The second body 120 is, for example, a host of a notebook computer. The support arm 130 is connected between the back surface S2 of the first body 110 and the second body 120 . Furthermore, the hinge assembly 140 is disposed on the support arm 130, so that the support arm 130 is respectively connected to the first body 110 and the second body 120 through the hinge assembly 140, so that the electronic device 100 can be as shown in FIGS. 1 to 3 As shown, the closed state of FIG. 1 is transformed into the unfolded state of FIG. 2 or FIG. 3 by the support arm 130 . Moreover, the first body 110 can move from the first position P1 shown in FIG. 2 to the second position P2 shown in FIG. 3 when the first body 110 is in the unfolded state through the support arm 130, so that the electronic device 100 can provide more user-friendly And comfortable viewing angle. In addition, it is also possible for the user to adjust the first body 110 to stay in any position between the first position P1 and the second position P2 to select an appropriate viewing angle.

In this embodiment, the first body 110 has a groove 112 on the back surface S2, and the first end E1 of the support arm 130 is pivotally connected in the groove 112 . Further, the shaft assembly 140 includes a first shaft 141, a second shaft 142 and a third shaft 143, wherein the third shaft 143 is connected between the second end E2 of the support arm 130 and the second body 120, so that the support arm 130 is rotated relative to the second body 120 along the second axis A2 via the third rotating shaft 143 . The bases 141 a of the first shaft 141 are disposed in pairs on opposite sides of the groove 112 , and the shaft 141 b of the first shaft 141 is pivotally connected between the first end E1 of the support arm 130 and the bases 141 a. Accordingly, the first body 110 can rotate relative to the support arm 130 along the first axis A1 through the first rotating shaft 141 , wherein the first axis A1 in this embodiment is parallel to the second axis A2.

It should be noted that the second shaft 142 is assembled between the pair of shaft portions 141b of the first shaft 141 and does not rotate with the shaft portion 141b. FIG. 4 is a partially equivalent schematic diagram of the electronic device in FIG. 3 at the second rotating axis. Please refer to FIG. 3 and FIG. 4 at the same time. In this embodiment, the second rotating shaft 142 is coaxial with the first rotating shaft 141 (with the second axis A2 as the mutual axis) and has at least one positioning surface 142a. When the first body 110 rotates along the second axis A2 relative to the support arm 130 , the positioning surface 142 a abuts against the back surface S2 of the first body 110 , thereby providing support for the first body 110 .

In other words, in this embodiment, the positioning surface 142a of the second rotating shaft 142 makes surface contact between the first body 110 and the second rotating shaft 142, which can increase the force applied to the first body 110 (that is, when the user presses When on the touch surface S1 ), the supporting force of the support arm 130 on the first body 110 . This effectively reduces the torque caused by the above-mentioned pressure on the support arm 130 , thus effectively preventing the first body 110 from shaking.

In this embodiment, one of the second rotating shaft 142 and the back surface S2 of the first body 110 is magnetic, and the other one of the second rotating shaft 142 and the back S2 of the first body 110 is magnetically permeable, thus causing the second The back surface S2 of the body 110 and the positioning surface 142 a of the second rotating shaft 142 can be firmly combined. In addition, the second rotating shaft 142 and the back surface S2 of the first body 110 may also have a magnetic coupling that attracts each other, which can also result in a stable combination of the two.

As shown in FIG. 4 , the state of the first body 110 in different positions is represented by a dotted line outline. Two adjacent positioning surfaces 142a are not parallel to each other, that is, there is an angle between two adjacent positioning surfaces 142a that is not 0 degrees and not 180 degrees, so that the cross section of the second rotating shaft 142 in this embodiment is polygonal. In this way, when the first body 110 is rotated relative to the support arm 130 (shown in FIG. 3 ), the first body 110 can be positioned on one of these positioning surfaces 142a, thereby allowing the user to further adjust for proper viewing perspective.

The arrangement form of the positioning surface on the second rotating shaft is not limited here. FIG. 5 is a partially equivalent schematic diagram of an electronic device at the second rotating shaft according to another embodiment of the present invention. Please refer to FIG. 5 . Unlike the above-mentioned embodiments, the second rotating shaft 242 is only provided with positioning surfaces 242a at its second quadrant, and these positioning surfaces 242a divide the second quadrant into four equal parts in section, that is, every The areas of the positioning surfaces 242a are equal.

FIG. 6 is a partially equivalent schematic diagram of an electronic device at a second rotating shaft according to yet another embodiment of the present invention. Please refer to FIG. 6 , different from the above embodiment, the second rotating shaft 342 has two positioning surfaces 342a and three positioning surfaces 342b, wherein the positioning surfaces 342b are located between the positioning surfaces 342a, and the positioning surfaces 342a are equal in area to each other. The positioning surfaces 342b are equal in area to each other, but the area of the positioning surface 342a is not equal to the area of the positioning surface 342b. In addition, FIG. 7 is a partially equivalent schematic diagram of an electronic device in another embodiment of the present invention at the second rotating shaft. Please refer to FIG. 7 , the second rotating shaft 442 has only one positioning surface 442a, so that the first body 110 can be quickly positioned on the positioning surface 442a when the first body 110 rotates. From the above, it can be seen that the designer can further design the positioning surface of the second rotating shaft according to the use environment and conditions of the electronic device, so that the first body has a viewing angle suitable for the user.

To sum up, in the above embodiments of the present invention, through the second rotating shaft assembled on the first rotating shaft, while the display element is rotated relative to the support arm through the first rotating shaft, the positioning surface of the second rotating shaft is aligned with the display The back surfaces of the components abut against each other to achieve a state of surface contact between the display component and the support arm, thereby providing effective support for the display component and avoiding shaking when the user operates the first body.

Furthermore, the designer can configure the positioning surface differently according to the use environment and conditions, so that the viewing angle of the first body can be changed according to the user's preference, so that the electronic device has a more friendly operation interface.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the present invention. scope.
