FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the invention.

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

FIG. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Please refer to FIG. 1, the electronic device 100 is, for example, a notebook computer. The present embodiment is a notebook computer in the unfolded state shown in the front view angle. It includes a first board body 110, a second board body 120, and a first shaft body P1. The second shaft body P2, the display screen 130, and the 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 can be rotated to open and close with each other through a hinge structure.

Furthermore, the second board 120 of this embodiment is disposed on the screen back cover 140, and then the first shaft body P1 and the second shaft body P2 are disposed, and the first board body 110 is connected to the display screen in sequence. The screen 130 is disposed thereon to 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 board 110 has a horseshoe-shaped opening 112, and the second board 120 has a linear track 121 and an arc-shaped track 122. The first shaft P1 is disposed on the first plate 110 and is movably (or rotatably) coupled to the linear rail 121. The second shaft P2 is disposed on the first plate 110 and is movably (or rotatably) coupled to the arc-shaped rail 122. The first shaft body P1 and the second shaft body P2 move along the linear rail 121 and the arc-shaped rail 122, respectively, so that the first plate 110 slides relative to the second plate 120, and the display screen 130 is disposed on the first plate 110 The first plate 110 slides relative to the second plate 120 along with it.

Furthermore, the first shaft body P1 of this embodiment is located outside the area surrounded by the horseshoe-shaped opening 112, the second shaft body P2 is located in the area surrounded by the horseshoe-shaped opening 112, and the first shaft body P1 and the second shaft body P1 are located outside the area surrounded by the horseshoe-shaped opening 112. The orthographic projection of the connecting line of the two-axis body P2 on the first board 110 will pass through the gap of the horseshoe-shaped opening 112. At the same time, in the first state shown in FIG. 1, the horseshoe-shaped opening 112 and the arc-shaped track 122 are in a state of being gripped with each other. Accordingly, the first board 110 and the display screen 130 on it can be driven by the user's force to make the first shaft P1 and the second shaft P2 move along the linear rail 121 and the arc rail 122, respectively. A sliding mechanism is formed in which the first board 110 and the display screen 130 thereon rotate relative to the second board 120 (and the screen back cover 140).

2 to 5 are schematic diagrams of the electronic device in FIG. 1 in different states, which are used to describe the gradual transition of the electronic device 100 from the first state shown in FIG. 1 to the second state shown in FIG. The first board 110 (and the display screen 130), The angle of rotation relative to the second board 120 (and the screen back cover 140) is 0 degrees, and then in FIGS. 2 to 5, they are 22.5 degrees, 45 degrees, 67.5 degrees, and 90 degrees in sequence. That is to say, the state difference between the display screen 130 in the first state and the display screen 130 in the second state is rotated 90 degrees counterclockwise.

Please refer to the first state of FIG. 1. The outline of the display screen 130 completely overlaps the outline of the screen back cover 140, which is the normal operating state that can be seen by the current notebook computer. As shown in FIG. 5, the outline of the display screen 130 The contour partially overlaps the contour of the screen back cover 140, and the center line C1 of the display screen 130 is overlapped with the center line C2 of the screen back cover 140. Simply put, by the above-mentioned sliding mechanism, the display screen 130 provided on the first board 110 can be switched between the landscape mode of FIG. 1 and the portrait mode of FIG. In the state, one end of the arc-shaped rail 122 and the second shaft portion P2 are located in the area surrounded by the horseshoe-shaped opening 112. In the second state, the other end of the arc-shaped rail 122 and the second shaft portion P2 are located in the horseshoe-shaped opening 112 in the second state. In the surrounding area, and during the sliding process from FIG. 1 to FIG. 5, the bottom edge of the display screen 130 is always on the bottom edge of the screen back cover 140, and in the second state of FIG. 5, the arc-shaped track 122 and the horseshoe-shaped opening 112 are also in a state of handshaking with each other.

In other words, the second board 120 and the display screen 130 on it will not interfere with the system host 170 during the sliding process. The reason is that the second board 120 and its upper linear rail 121 and arc rail 122 When the first plate body 110 rotates with the display screen 130 on it, it can be raised first and then lowered. In other words, the center of curvature of the arc-shaped track 122 in this embodiment is located at the center of the linear track 121 The two opposite sides of the arc-shaped track 122 allow the second shaft P2 to move along the arc-shaped track 122 and have the same displacement trend as the first shaft P1 moves along the linear track 121, so that the first plate 110 can be smoothly moved. In contrast, the display screen 130 above can be raised first (FIGS. 1 to 3) and then lowered (FIGS. 3 to 5).

Furthermore, in this embodiment, the movable stroke L1 of the first shaft body P1 on the linear rail 121 is equivalent to half of the movable stroke L2 of the second shaft body P2 on the arc-shaped rail 122, so that the first plate When the body 110 and the display screen 130 are in the 45-degree state shown in FIG. 3, the first shaft P1 runs to the upper end of the linear track 121, and the second shaft P2 runs to the inflection point of the arc-shaped track 122, and At this time, the first shaft body P1 and the second shaft body P2 are aligned with the center of curvature of the arc-shaped track 122. After that, as shown in FIGS. 3 to 5, the second shaft P2 moves to the other end of the arc-shaped rail 122, and the first shaft P1 moves to the lower end of the linear rail 121 to align the first plate The body 110 (and the display screen 130) causes the lowering motion.

It should also be mentioned that the linear track 121 and the arc-shaped track 122 of the second board 120 are always hidden between the first board 110 and the screen back cover 140 during the sliding process of FIGS. As far as the user is concerned, only the front display screen 130 and the rear screen back cover 140 and the second plate 120 partially exposed from the horseshoe-shaped opening 112 will be seen, and the linear rail 121 and the arc-shaped rail 122 will not be seen at all. The electronic device 100 can maintain its external aesthetics even during the sliding process.

1 again, in this embodiment, the electronic device 100 further includes at least one elastic member 150, and one end of the elastic member 150 is pivotally connected to the second board 120, and the other end of the elastic member 150 is connected to the first shaft body P1. This embodiment is composed of multiple parallel springs Take the elastic component as an example, but it does not limit its form.

Please refer to FIGS. 2 to 5, especially the changing trend of the elastic member 150. In this embodiment, for the first shaft body P1, when the first shaft body P1 reaches the upper end point of the linear rail 121, the elastic member 150 has the maximum amount of deformation, while for the second shaft body P2, When the second shaft body P2 travels to the inflection point of the arc-shaped track 122, the elastic member 150 has the maximum amount of deformation. 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 amount of deformation. In this way, the elastic force accumulated by the elastic member 150 can be used to drive the first board 110 (and the display screen 130 thereon) to reset to the first state in FIG. 1 or the second state in FIG. 5. That is to say, the force required by the user to drive the first board 110 (and the display screen 130 thereon) only needs to complete the sliding process of FIGS. 1 to 3, or FIGS. 5 to 3, and then only need to apply more force. After the second shaft body P2 passes the inflection point of the arc-shaped track 122, it can be reset to the second state or the first state by the elastic force of the elastic member 150, thereby providing a labor-saving effect on the sliding process.

On the other hand, please refer to FIG. 1 again. In this 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 threaded through the escape opening 123 It is also electrically connected to the display screen 130, for example, to allow the cable 160 to reserve a length between the display screen 130 and the screen back cover 140, so that the display screen 130 can drive the cable 160 at the horseshoe-shaped opening 112 during the sliding process Stretch or shrink. Furthermore, the display screen 130 has a connector 131 disposed on the bottom side of the display screen 130 for connecting one end of the cable 160, and the other end of the cable 160 passes through After passing through the avoiding opening 123, it can be electrically connected to the screen back cover 140, and particularly extend to the system host 170 through the screen back cover 140, so as to achieve the purpose of electrical connection.

Furthermore, the arc-shaped track 122 is located between the linear track 121 and the avoiding opening 123, and the connector 131 is located at the bottom side of the horseshoe-shaped opening 112. Furthermore, the avoiding opening 123 of this embodiment is located in the area surrounded by the line L3 between the opposite ends of the arc-shaped track 122 and the arc-shaped track 122, and is also located in the circular area C3 formed by the expansion of the arc-shaped track 122. Inside (for identification, the line L3 and the circular area C3 are only shown in FIG. 1 as an example). Therefore, in the process of the display screen 130 sliding with the first board 110 relative to the second board 120 (and the screen back cover 140), the orthographic projection of the opening 123 on the first board 110 is prevented from at least partially overlapping the horseshoe shape Opening 112. As shown in FIGS. 1 to 4, the avoiding opening 123 is completely exposed from the horseshoe-shaped opening 112, and as shown in FIG. 5, the avoiding opening 123 is partially exposed from the horseshoe-shaped opening 112. This allows the cable 160 to pass through the avoiding opening 123 and be located at one of the branches of the horseshoe-shaped opening 112 in the first state, and in the second state, the cable 160 passes through the avoiding opening 123 and reaches the horseshoe-shaped opening 112. Another branch.

In other words, the cable 160 is flexible, 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 subject to any structural damage during the body sliding process. put one's oar in.

In summary, in the above-mentioned embodiments of the present invention, the first board of the electronic device has a horseshoe-shaped opening, and the second board has a linear track and an arc-shaped track, and the first board is provided by the first shaft. And movably coupled to the linear track, the second shaft body is provided with the first plate body and movably coupled to the arc-shaped track, and the first shaft body is located in a horseshoe shape Outside the area surrounded by the opening, the second shaft is located in the area surrounded by the horseshoe-shaped opening. Due to the above-mentioned component configuration, the first plate body can slide relative to the second plate body by moving the first shaft body and the second shaft body respectively on the linear track and the arc-shaped track.

Furthermore, the arrangement of the curved track and the linear track enables the bottom edge of the display screen to always be on the bottom edge of the screen back cover when the display screen slides with the first board body, which is because the first board body and the The upper display screen produces a movement mode of first rising and then falling during the sliding process along the linear and arc-shaped tracks. Therefore, after the display screen is converted from the horizontal state to the upright state, its center line will be in line with the back of the screen. The center lines of the cover overlap and are centered so as to conform to the user's viewing angle without shifting. In addition, since the second board with linear rails and arc-shaped rails is substantially hidden between the first board and the screen back cover, the overall appearance of the electronic device can be maintained during the sliding process.

On the other hand, the second board also has an escape opening to allow the cable that is electrically connected between the display screen and the screen back cover to movably pass through the opening and the horseshoe-shaped opening, and follow the sliding of the display screen During the process, the flexible cable can be freely deformed at the horseshoe-shaped opening without interference from the surrounding structure. According to this, the bodies of the electronic device can simultaneously rotate through the process of movement, thereby adjusting the relative position between the bodies, and the relative movement between the components can also maintain its degree of freedom due to the above configuration. Therefore, the electronic device can smoothly provide additional operation modes according to usage requirements.
