Referring to FIG. 1 , the electronic device 100 includes a first body 110 , a second body 120 , and a pivoting module 130 . The second body 120 is electrically connected to the first body 110. In this embodiment, the first body 110 is a tablet computer, and the second body 120 is an external keyboard module for illustration. However, in other embodiments, the second body 120 may be other external electronic modules that are combined with the tablet computer, and the present invention is not limited thereto. As shown in FIG. 1 , when the first body 110 and the second body 120 of the electronic device 100 of the present embodiment are in the overlapping position, the hidden pivot module 130 is not seen. In other words, when the first body 110 and the second body 120 are in the coincident position, the orthographic projections of the first body 110 and the second body 120 on a plane S completely overlap each other.

2A to 2C are schematic views respectively showing the electronic device of FIG. 1 in different states. Referring to FIG. 1 , FIG. 2A and FIG. 2C , in the embodiment, the first body 110 of the electronic device 100 is rotatable relative to the second body 120 on the plane S by the pivoting module 130 . This is different from the conventional technique in that the orbital body causes the body to be relatively slipped and then flipped, and the conventional device can be prevented from hiding the track in appearance. In contrast, the electronic device 100 of the present invention has a more compact structure. The appearance, and thus the body 110 or 120, can have more space to configure related electronic modules (such as system ports).

In this embodiment, the electronic device 100 is sequentially converted from the state of FIG. 1 , FIG. 2A to FIG. 2C , so that the first body 110 can be positioned relative to the second body 120 on the plane S ( FIG. 1 ). , shown in Figure 2B) and a rotation state (as shown in Figure 2A). In other words, the first body 110 rotates back and forth between a coincident position as shown in FIG. 1 and a deployed position as shown in FIG. 2B, wherein the first body in the deployed position is rotated relative to the coincident position. 180 degrees. This allows the electronic device 100 in this state to additionally provide another use state of the user, and allows the user to conveniently use the electronic device 100 while the body is lying or leaning against the body.

Referring to FIG. 2B and FIG. 2C , after the electronic device 100 is in the deployed position, the first body 110 can be erected relative to the second body 120 by the pivoting module 130 to enable the first body 110 and the second body. The body 120 is in an upright position, and the angle of the first body 110 relative to the second body 120 in this state is adjusted according to the viewing angle of the user. In addition, in the embodiment, the electronic device 100 is sequentially changed from the coincident position to the deployed position, and then converted from the expanded position to the set position. Therefore, when the electronic device 100 is to be folded, the above steps can be reversed, and the first body 110 is changed from the upright position to the deployed position, and then the expanded position is changed to the coincident position.

3A to 3C are partial side views of the electronic device of FIG. 1 in different states, respectively. 3A is a view of the coincident position illustrated in FIG. 1, FIG. 3B in comparison with the rotated state illustrated in FIG. 2A, and FIG. 3C in comparison with the expanded position of FIG. 2B. Referring to FIG. 3A to FIG. 3C and FIG. 1 , FIG. 2A and FIG. 2B , it is noted that when the electronic device 100 is in a rotating state, the relative distance between the first body 110 and the second body 120 is greater than The relative distance between the first body 110 and the second body 120 when the electronic device 100 is in the coincident position and the deployed position. In other words, when the electronic device 100 is in the rotating state, a gap exists between the first body 110 and the second body 120 so that the first body 110 does not rub against each other when rotated relative to the second body 120. When the electronic device 100 is in the overlapping position or the deployed position, the first body 110 substantially conforms to the second body 120.

4A is a schematic diagram of a pivoting module in the electronic device of FIG. 1. 4B is an exploded view of the pivoting module of FIG. 4A. Referring to FIG. 4A and FIG. 4B simultaneously, in detail, in the state illustrated in FIG. 1 , the pivoting module 130 received in a recess 120 a of the second body 120 has a first axis Z and a second The axis T, and the first axis Z and the second axis T are perpendicular to each other. When the first body 110 rotates relative to the second body 120 along the first axis Z, it can be switched between the coincident position of FIG. 1 and the deployed position of FIG. 2B, and when the first body 110 is opposite to the second body 120 The two axes T are rotated to switch between the deployed position of Figure 2B and the upright position of Figure 2C. In other words, after the first body 110 is rotated in parallel with the second body 120 from the overlapping position to the deployed position, the first body 110 can stand on the second body 120 by the pivoting module 130, so that the first body 110 is Not parallel to the second body 120, with such a stand-up position, the user can use the electronic device 100 as if using a notebook computer.

Furthermore, the pivoting module 130 includes a base 131, a first rotating shaft 132, a fixing ring 133, a positioning ring 134, an annular elastic piece 135, an upper cover ring 136, and a second rotating shaft 137. As shown in FIG. 4B, in the present embodiment, the base 131 has a pivot portion 131a and a body portion 131b. The first rotating shaft 132 is disposed on the main body portion 131b, and the second rotating shaft 137 is disposed on the pivoting portion 131a. The first rotating shaft 132 is assembled to the first body 110 such that the first body 110 and the second body 120 are rotatable in parallel with each other along the first axis Z by the first rotating shaft 132.

The second rotating shaft 137 is assembled between the pivoting portion 131a of the base 131 and the second body 120 through a locking piece 137a, and the second rotating shaft 137 (having the second axis T) is perpendicular to the first rotating shaft 132 (having the first axis Z) ). The first body 110 and the second body 120 can be rotated non-parallel to each other along the second axis T by the second rotating shaft 137. In other words, the first body 110 is rotated from the state parallel to the second body 120 to the upright state by the second rotating shaft 137, so that the first body 110 is not parallel to the second body 120, and the base 131 is also The pivotal structure existing between the two rotating shafts 137 and the locking piece 137a adjusts the relative angles of the body 110, 120 when the standing position is set.

The fixing ring 133 is fixed to the first body 110 and sleeved to the first rotating shaft 132. In the embodiment, the fixing ring 133 has two positioning grooves 133a. The positioning ring 134 is sleeved to the first rotating shaft 132 and stacked on the fixing ring 133. The positioning ring 134 has two convex portions 134a facing the fixing ring 133. In addition, the pivoting module 130 further includes an annular elastic piece 135 and an upper cover ring 136. The annular elastic piece 135 is sleeved to the first rotating shaft 132 and stacked on the fixing ring 133. The upper cover ring 136 is locked to the first rotating shaft 132 by a screw 136a to sandwich the fixing ring 133, the positioning ring 134 and the annular elastic piece 135 between the upper cover ring 136 and the base 131. In the present embodiment, the annular elastic piece 135 is, for example, wavy to provide a vertical direction, that is, an elastic force in the direction of the first axis Z to the fixing ring 133, so that the fixing ring 133 and the positioning ring 134 can abut each other.

According to this, when the first body 110 is rotated relative to the second body 120 on the plane S by the pivoting module 130, the fixing ring 133 and the positioning ring 134 are relatively rotated along the first rotating shaft 132, which is as shown in FIG. 2A. It is shown that, in view of the elastic effect of the annular elastic piece 135, the fixing ring 133 and the positioning ring 134 are coaxially rotated with each other along the surface contour of each other. In other words, during the relative rotation of the retaining ring 134 and the retaining ring 133, the projection 134a will lift the retaining ring 133 away from the retaining ring 134. In this way, the first body 110 and the second body 120 have the predetermined distance in the rotated state as shown in FIG. 2A, thereby preventing the bodies 110 and 120 from interfering with each other during the rotation, that is, at the first When the body 110 is rotated in parallel with respect to the second body 120, friction does not occur with each other.

Moreover, when the convex portion 134a is correspondingly engaged with the positioning groove 133a, the first body 110 is positioned at the position of FIG. 1 or FIG. 2B, and the user is in the coincident position and the deployed position of the body 110, 120. Can have a clear positioning feel. In addition, the positioning ring 134 further has a guiding slope 134b (only one side of one of the protrusions 134a is shown) on both sides of the convex portion 134a to allow the positioning ring 134 and the fixing ring 133 to rotate relative to each other. Can be smoother and reduce interference between the two

In this embodiment, the two positioning grooves 133a of the fixing ring 133 and the two convex portions 134a of the positioning ring 134 are respectively located at opposite ends of the diametrical direction, thereby rotating the first body 110 from the coincident position of FIG. After 180 degrees, it is positioned in the unfolded position of Figure 2B. However, the embodiment does not limit the number and position of the protrusion 134a or the recess 133a on the fixing ring 134 and the positioning ring 133, respectively. In another embodiment not shown, the designer can select according to the rotation of the body. The position of the convex portion and the groove is appropriately changed by the angle.

In summary, the electronic device of the present invention passes through the pivoting module, and the first body relative to the second body can be sequentially switched between a reclosing position, a deployed position and a standing position, and is in a coincident position. When the position between the expansion positions is changed, the relative distance between the two bodies becomes larger, so that no friction occurs between the two bodies during the conversion.
