fig. 2 to 5 are schematic diagrams of the electronic device in fig. 1 in different states.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Referring to fig. 1, an electronic device 100 is, for example, a notebook computer, and the embodiment shows the notebook computer in an unfolded state from a front view, and includes a first board 110, a second board 120, a first shaft P1, a second shaft P2, a display screen 130, and a screen back cover 140, wherein the electronic device 100 further includes a system host 170, and the screen back cover 140 and the system host 170 are rotated to open and close each other through a hinge structure.

Furthermore, the second board 120 of the present embodiment is disposed on the screen back cover 140, and then the first shaft P1 and the second shaft P2 are disposed thereon, so as to sequentially form a stacked structure of the screen back cover 140, the second board 120, the first board 110 and the display screen 130.

More importantly, the first plate 110 has a horseshoe-shaped opening 112, and the second plate 120 has a linear track 121 and an arc-shaped track 122. The first shaft P1 is disposed on the first board 110 and movably (and also rotatably) coupled to the linear rail 121. The second shaft P2 is disposed on the first plate 110 and movably (and rotatably) coupled to the arc track 122. The first shaft P1 and the second shaft P2 respectively move along the linear track 121 and the arc track 122, so that the first board 110 slides relative to the second board 120, and the display screen 130 is, for example, a display screen, which is disposed on the first board 110 and slides with the first board 110 relative to the second board 120.

Further, in the present embodiment, the first shaft P1 is located outside the area surrounded by the horseshoe-shaped opening 112, the second shaft P2 is located inside the area surrounded by the horseshoe-shaped opening 112, and an orthogonal projection of a connection line between the first shaft P1 and the second shaft P2 on the first plate 110 passes through the gap of the horseshoe-shaped opening 112. Meanwhile, in the first state shown in fig. 1, the horseshoe-shaped opening 112 and the arc-shaped rail 122 are in a mutually engaged state. Accordingly, the first board 110 and the display screen 130 thereon can be driven by the user to move the first shaft P1 and the second shaft P2 along the linear track 121 and the arc track 122, respectively, so as to form a sliding mechanism for the first board 110 and the display screen 130 thereon to rotate relative to the second board 120 (and the screen back cover 140).

Fig. 2 to fig. 5 are schematic diagrams of the electronic device of fig. 1 in different states, which are used to describe that the electronic device 100 gradually transitions from the first state shown in fig. 1 to the second state shown in fig. 5, wherein a rotation angle of the first plate 110 (and the display screen 130) shown in fig. 1 relative to the second plate 120 (and the screen back cover 140) is 0 degree, and then the rotation angles of the first plate 110 (and the display screen 130) shown in fig. 2 to fig. 5 are 22.5 degrees, 45 degrees, 67.5 degrees, and 90 degrees in sequence. That is, the display screen 130 in the first state and the display screen 130 in the second state have a difference in state of being rotated 90 degrees counterclockwise.

Referring to the first state of fig. 1, the outline of the display screen 130 completely overlaps the outline of the screen back cover 140, i.e. the normal operation state seen in the notebook computer at present, and as shown in fig. 5, the outline of the display screen 130 partially overlaps the outline of the screen back cover 140, and the center line C1 of the display screen 130 coincides with the center line C2 of the screen back cover 140. In short, by the above-mentioned sliding mechanism, the display screen 130 disposed on the first board 110 can be switched between a landscape (landscaped) mode of fig. 1 and a portrait (Portrait) mode of fig. 5, wherein in the first state, one end of the curved rail 122 and the second shaft P2 are located in the area surrounded by the horseshoe-shaped opening 112, in the second state, the other end of the curved rail 122 and the second shaft P2 are located in the area surrounded by the horseshoe-shaped opening 112, and further, during sliding from fig. 1 to fig. 5, the bottom edge of the display screen 130 is constantly located above the bottom edge of the screen back cover 140, and in the second state of fig. 5, the curved rail 122 and the horseshoe-shaped opening 112 are also in an inter-engaged state.

In other words, the second board 120 and the display screen 130 thereon will not interfere with the system host 170 during the sliding process, because the second board 120 and the linear track 121 and the arc track 122 thereon are disposed, and the first board 110 and the display screen 130 thereon can be lifted and then lowered when rotating together. That is to say, the curvature center of the arc-shaped track 122 of the present embodiment is located at two opposite sides of the linear track 121 on the arc-shaped track 122, so that the second shaft P2 has the same displacement trend as the first shaft P1 moves along the linear track 121 when moving along the arc-shaped track 122, so as to smoothly enable the first plate 110 and the display screen 130 thereon to be lifted first (fig. 1 to 3) and then lowered (fig. 3 to 5).

Furthermore, in the embodiment, the movable stroke L1 of the first shaft P1 on the linear track 121 is equal to half of the movable stroke L2 of the second shaft P2 on the arc track 122, so that the first shaft P1 travels to the upper end point of the linear track 121 and the second shaft P2 travels to the inflection point of the arc track 122 when the first plate 110 and the display screen 130 are in the 45-degree state shown in fig. 3, and the first shaft P1 and the second shaft P2 are aligned with the curvature center of the arc track 122. Thereafter, as shown in fig. 3 to 5, the second shaft P2 travels to the other end of the arc-shaped track 122, and the first shaft P1 moves to the lower end of the linear track 121 to cause the first plate 110 (and the display screen 130) to descend.

It should be noted that the linear track 121 and the arc track 122 of the second board 120 are constantly hidden between the first board 110 and the screen back cover 140 during the sliding process of fig. 1 to 5, so that for a user, only the front display screen 130 and the rear screen back cover 140 and the second board 120 partially exposed from the horseshoe-shaped opening 112 are seen, but the linear track 121 and the arc track 122 are not seen at all, so that the electronic device 100 can maintain the external appearance thereof even during the sliding process.

Referring to fig. 1 again, in the present embodiment, the electronic device 100 further includes at least one elastic element 150, one end of the elastic element 150 is pivotally connected to the second board 120, and the other end of the elastic element 150 is connected to the first shaft P1. The present embodiment is an example of an elastic component composed of a plurality of springs connected in parallel, but the form is not limited thereto.

Please refer to fig. 2 to fig. 5, in particular, the variation trend of the elastic member 150. In the embodiment, for the first shaft P1, the elastic member 150 has the maximum deformation amount when the first shaft P1 travels to the upper end point of the linear track 121, and for the second shaft P2, the elastic member 150 has the maximum deformation amount when the second shaft P2 travels to the inflection point of the arc track 122. In other words, when the electronic device 100 is in the first state shown in fig. 1 or the second state shown in fig. 5, the elastic member 150 is not deformed, and when the electronic device 100 is in the state shown in fig. 3, the elastic member 150 has the maximum deformation amount. In this way, the elastic force accumulated by the elastic member 150 can serve to drive the first plate 110 (and the display screen 130 thereon) to return to the first state of fig. 1 or the second state of fig. 5. That is, the user only needs to apply force to drive the first plate 110 (and the display screen 130 thereon) to complete the sliding process of fig. 1 to 3 or fig. 5 to 3, and then only needs to apply force to make the second shaft P2 pass through the inflection point of the arc-shaped track 122, and then the second shaft P2 can be reset to the second state or the first state through the elastic force of the elastic member 150, so as to provide a labor-saving effect to the sliding process.

On the other hand, referring to fig. 1 again, in the present embodiment, the second board 120 further has an escape opening 123, and the electronic device 100 further includes a cable 160, wherein the cable 160 is movably disposed through the escape opening 123 and electrically connected to the display screen 130, for example, the cable 160 is allowed to have a reserved length between the display screen 130 and the screen back cover 140, so that the display screen 130 can drive the cable 160 to stretch or contract at the horseshoe-shaped opening 112 during the sliding rotation. Further, the display screen 130 has a connector 131 disposed on a bottom side thereof for connecting one end of the cable 160, and another end of the cable 160 is electrically connected to the screen back cover 140 after passing through the avoiding opening 123, and particularly extends to the system host 170 through the screen back cover 140 for electrical connection.

Further, the curved track 122 is located between the linear track 121 and the escape opening 123, and the connector 131 is located at the bottom side of the horseshoe-shaped opening 112. Further, the avoidance opening 123 of the present embodiment is located in an area surrounded by the connecting line L3 at the two opposite ends of the arc-shaped track 122 and the arc-shaped track 122, and is further located in a circular area C3 formed by expanding the arc-shaped track 122 (for identification, the connecting line L3 and the circular area C3 are only marked in fig. 1 as an example). Therefore, during the sliding rotation of the display screen 130 relative to the second plate 120 (and the screen back cover 140) along with the first plate 110, the orthographic projection of the avoidance opening 123 on the first plate 110 at least partially overlaps the horseshoe-shaped opening 112. As shown in fig. 1-4, the bypass opening 123 is fully exposed from the horseshoe-shaped opening 112, while as shown in fig. 5, the bypass opening 123 is partially exposed from the horseshoe-shaped opening 112. This allows the cable 160 to pass through the bypass opening 123 and be located in one branch of the horseshoe opening 112 in the first state, and allows the cable 160 to pass through the bypass opening 123 and be located in the other branch of the horseshoe opening 112 in the second state.

In other words, the cable 160 has flexibility, and the horseshoe-shaped opening 112 can be regarded as a reserved space for the cable 160 to be freely deformed, so that the cable 160 is not interfered by any structure during the sliding process of the body.

In summary, in the embodiments of the invention, the first plate of the electronic device has a horseshoe-shaped opening, the second plate has a linear track and an arc track, the first plate is disposed on the first shaft and movably coupled to the linear track, the second shaft is disposed on the first plate and movably coupled to the arc track, the first shaft is located outside an area surrounded by the horseshoe-shaped opening, and the second shaft is located inside the area surrounded by the horseshoe-shaped opening. Due to the arrangement of the components, the first shaft body and the second shaft body respectively move on the linear track and the arc track, so that the first plate body can slide relative to the second plate body.

Moreover, the arrangement of the arc-shaped track and the linear track can ensure that the bottom edge of the display screen is constantly positioned on the bottom edge of the screen back cover when the display screen slides along the first plate body, namely, the first plate body and the display screen thereon generate a rising-falling movement mode in the sliding process along the linear track and the arc-shaped track, and therefore, after the display screen is converted from a transverse state to an upright state, the central line of the display screen is superposed with the central line of the screen back cover to be centered, so that the display screen accords with the visual angle of a user and is not deviated. In addition, the second board body with the linear track and the arc track is substantially hidden between the first board body and the screen back cover, so that the appearance integrity of the electronic device can be still maintained in the sliding and rotating process.

On the other hand, the second plate body is also provided with an avoidance opening, so that the cable electrically connected between the display screen and the screen back cover can movably pass through the opening and the horseshoe-shaped opening, and along with the sliding process of the display screen, the flexible cable can freely deform at the horseshoe-shaped opening without being interfered by peripheral structures. Accordingly, the bodies of the electronic device can simultaneously rotate through the moving process, so as to adjust the relative positions of the bodies, and the relative movement between the members can maintain the degree of freedom due to the configuration, so that the electronic device can smoothly provide additional operation modes according to the use requirements.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
