Accordingly, the screen in the first state is adjacent to the base on which it is set, and the screen in the second state is far from the base on which it is set, so a shift (away from the base) occurs during the rotation of the screen. (Sideshift) effect.

FIG. 1A is a schematic diagram of an electronic device according to an embodiment of the present invention. FIG. 1B is a schematic diagram of the electronic device of FIG. 1A in another state. FIG. 2 illustrates the electronic device of FIGS. 1A and 1B from another perspective. Cartesian coordinates X-Y-Z are also provided here to facilitate component description. Please refer to FIG. 1A , FIG. 1B and FIG. 2 at the same time. In this embodiment, the electronic device 100 includes a base 110 , a screen rotating mechanism RA and a rotating shaft 120 , wherein the screen rotating mechanism RA includes a screen 140 and a back plate 150 . The screen 140 is, for example, It is a touch screen, the base 110 has a recess R1, the rotating shaft 120 is connected between the base 110 and the back plate 150, the back plate 150 and the screen 140 are rotated relative to the base 110 along the Y axis through the rotating shaft 120 to move out of the recess R1 or accommodated in recess R1.

Here, the base 110 is, for example, a wall or a partition, which accommodates the screen 140 and the back plate 150 by means of the recess R1 to generate the design concept of a hidden screen, that is, the screen 140 can not only be regarded as embedded in the wall Or the partition board can also be lifted from the wall or the partition board according to the user's needs, which is convenient for the user to operate.

Furthermore, as shown in FIG. 1A and FIG. 1B , the screen rotation mechanism RA removed from the recess R1 can further perform self-rotation along the Z axis (at this time, the screen rotation mechanism RA is regarded as having been relative to the base. 110 is rotated 90 degrees along the Y axis), so that the screen 140 can be in the first state shown in FIG. 1A , that is, the portrait orientation, which is regarded as 0 degrees here, and converted to the second state shown in FIG. 1B . The state, that is, the landscape orientation, is regarded as 90 degrees here, that is, the difference between the two states is that the screen is rotated 140 degrees by 90 degrees.

Referring to FIG. 2 again, in this embodiment, the screen 140 includes a main body 143 , a first guide pin 141 and a second guide pin 142 . The back plate 150 includes a body 153 , a linear track 151 disposed on the body 153 , a curved track 152 and a wiring area 154 , wherein the first guide pin 141 is movably and pivotally connected to the linear track 151 , and the second guide pin 142 can The curved track 152 is movably and pivotably connected. Accordingly, the screen 140 and the backplane 150 rotate relative to each other along the Z-axis parallel to each other to generate the above-mentioned first state and second state. As shown in the figure, the screen 140 in the first state is adjacent to the base 110, and the screen 140 in the second state is far away from the base 110. It is clear from this that the screen 140 in the second state is relative to the screen 140 in the first state. The state screen 140 also increases the offset travel in the direction of the positive X-axis. In this way, for the user, the screen rotation mechanism RA also increases the state of causing the screen 140 to deviate from the base 110 to generate a displacement F1 during the rotation process, thereby increasing the space between the screen 140 and the base 110 and avoiding the base 110. 110 interferes when the user manipulates the screen 140 , which is beneficial to improve the convenience for the user to operate the screen 140 .

The following will further describe the structural design of the screen rotation mechanism RA on the backplane 150, that is, how to provide the linear track 151 and the curved track 152, so that the screen 140 can generate the desired effect relative to the first state when the screen 140 is in the second state. The required displacement F1.

3A to 3C are schematic diagrams showing the relevant structural conditions of the screen rotation mechanism. Please refer to FIGS. 3A to 3C respectively and compare with FIG. 2 . Here, the structural conditions required before obtaining the track design are described first, and for ease of identification, the relevant drawings only show the main body 143 of the screen 140 as an example. It should be noted that the relevant structural conditions of this embodiment are based on the premise that the body 143 of the screen 140 further generates a displacement F1 after being rotated from the first state (0 degrees) to the second state (90 degrees).

First of all, in this embodiment, the overlapping area of the orthographic projection of the body 143 of the screen 140 in the first state and the body 143 of the screen 140 in the second state forms the first overlapping area A1, that is, the screen in the first state The body 143 of the screen 140 in the second state is orthographically projected on the body 143 of the screen 140 in the second state to form an overlapping area, which is the first overlapping area A1. Similarly, if the body 143 of the screen 140 in the second state is orthographically projected on the The body 143 of the screen 140 in the first state also forms the first overlapping area A1 of the same range. Meanwhile, the body 143 of the screen 140 in this embodiment is rectangular and has four endpoints. After the aforementioned rotation from the first state to the second state, these four endpoints form four moving distances d1, d1, d2, d3, and d4, and in this embodiment, these four moving distances have a relative relationship d1>d2>d4>d3.

Next, in FIG. 3B , the first overlapping area A1 formed by the above-mentioned rotation of the main body 143 by 90 degrees is also rectangular, and the first overlapping area A1 is further divided into four isosceles triangles by the diagonal of the rectangle. area, and the four isosceles triangle areas correspond to the aforementioned four moving distances d1 to d4 respectively, wherein the isosceles triangle area IT1 corresponds to the smallest of the four moving distances d1 to d4, that is, the moving distance d3, while the isosceles triangle area IT1 corresponds to the smallest of the four moving distances d1 to d4. The triangular area IT2 corresponds to the second largest of the four moving distances d1 to d4, that is, the moving distance d2. The so-called correspondence here means that in the isosceles triangle area and the moving distance corresponding to each other, the base of the isosceles triangle area is located between the vertex angle of the isosceles triangle area and the corresponding moving distance. For example, as shown in FIG. 3B , the base of the isosceles triangle area IT1 is located between the vertex angle θ1 of the isosceles triangle area IT1 and the moving distance d3, so the isosceles triangle area IT1 is described as corresponding to the moving distance d3. The base of the isosceles triangle area IT2 is located between the vertex angle θ1 of the isosceles triangle area IT2 and the moving distance d2, so the isosceles triangle area IT2 is described as corresponding to the moving distance d2.

Next, the isosceles triangle area IT1 is divided into a pair of right-angled triangle areas that are symmetrical to each other by the bisector of its vertex angle θ1, which corresponds to the second largest of the four moving distances d1 to d4 (that is, the moving distance d2). ) is the first right triangle area RT1. In addition, for the isosceles triangle region IT2, the bisector of its vertex angle θ2 also separates a pair of right-angled triangle regions that are symmetrical to each other, which corresponds to the smallest of the four moving distances d1 to d4 (that is, the moving distance d3 ) is the second right triangle area RT3.

It should be noted that, as shown in FIG. 1A and FIG. 1B , the main body 143 of the screen 140 rotates in the first direction C1 relative to the main body 153 of the backplane 150 to switch from the first state to the second state, while in FIG. 3C , the aforementioned first right triangle region RT1 is rotated along the second direction C2 to form a reverse right triangle region RT2, wherein the first right triangle region RT1 and the reverse right triangle region RT2 form a second overlapping region A2, and the first The direction C1 and the second direction C2 are opposite to each other. That is to say, the reverse right triangle region RT2 is equivalent to rotating the first right triangle region RT1 from the second state to the first state along with the body 143 of the screen 140 . The center of rotation of 143 is the same. Accordingly, the first right triangle region RT1 forms a reverse right triangle region RT2 after the rotation, and the second overlapping region A2 is formed before the rotation. At this point, the description of the relevant structural conditions of the screen rotation mechanism RA is completed.

4A to 4C are schematic diagrams illustrating the design process of the linear track. It should be noted here that, as shown in FIG. 2 , the linear track 151 is a structural feature on the backplane 150 , that is, the required linear track can be formed on the backplane 150 by the means described later in this embodiment. 151, and more importantly, for the sake of appearance, the screen 140 and the backplane 150 are not exposed in the state shown in FIG. 1A or FIG. 1B so that the connection structure between them is not exposed. In other words, in actual operation, the designer can simulate the optimal design of the relevant structural features on the body 153 of the backplane 150 according to the design logic described later, such as obtaining the linear track 151 , the curved track 152 and the wiring area 154 . The optimal arrangement position and minimum size are equivalent to minimizing the selectable area of the backplane 150 , or obtaining more remaining space on the backplane 150 to facilitate the arrangement of other components.

First, please refer to FIG. 3C and FIG. 4A , select multiple points in the second overlapping area A2 obtained above, and let these points rotate as the body 143 of the screen 140 rotates between the first state and the second state The moving distance of each point between the first state (0 degrees) and the second state (90 degrees) is obtained, and the number of these points is not limited here, which can be adjusted according to the relevant capabilities of the computer. Next, the moving distances of these points are sorted, and the point with the shortest moving distance is selected as the linear reference point, as shown in Fig. 4A, the point with the shortest moving distance is obtained here, which is a bit At the position P1, and in the second state (90 degrees), it is at the position P2, and the linear reference line L1 runs through the position P1 and the position P2. This is equivalent to constraining the linear track 151 on the linear reference line L1.

Next, as shown in FIG. 4B , the position P1 in the first state (0 degree) is connected to the two end points N2 and N1 of the main body 143 respectively to form relative distances d5 and d6 , and the smaller one (in this case) is selected. In the embodiment, d6<d5), after that, the linear reference line L1 is used as the movement trajectory restriction of the point located at the position P1, and the main body 143 is rotated by 45 degrees (the third state), so that the end point N1 of the main body 143 is rotated to At the end point N1a, the relative distance d6 will be rotated to the relative distance d6a, and the position P3 can be obtained at this time. This means that the point originally at the position P1 will move to the position P3 after the body 143 is rotated by 45 degrees.

Accordingly, the linear rail 151 shown in FIG. 2 can be obtained by connecting the position P1 and the position P3. That is to say, the process of FIGS. 4A to 4B and the above steps are used to design the end point E1 and the end point E2 of the linear track 151 (as shown in FIG. 2 ), wherein the end point E1 is the above-mentioned position P1 , and The endpoint E2 is the above-mentioned position P3. More specifically, this is to limit the stroke of the first guide pin 141 on the linear track 151 by obtaining the end points E1 and E2 of the linear track 151 , wherein the end point E1 is the first guide pin 141 in the linear track 151 . The starting point and the ending point of the track 151, and the end point E2 is used as the turning point of the first guide pin 141 in the linear track 151, that is, when the screen 140 is switched from the first state to the second state, the first guide pin from the end After the point E1 is moved to the end point E2, the end point E2 is moved back to the end point E1.

It should also be noted that, as mentioned above, the structural relationship of this embodiment is based on the premise that the body 143 further generates a displacement F1 after rotating from the first state (0 degrees) to the second state (90 degrees). If the length of the track is shorter than the above, the screen 140 will obviously not be able to generate the required displacement F1, and if the length of the obtained linear track is longer than the above, it will obviously exceed the first overlapping area A1 and be exposed, resulting in an unsightly visual effect. .

Please refer to FIG. 2 , FIG. 3B and FIG. 4C at the same time, the linear track 151 obtained based on the above obviously has the following characteristics: the linear track 151 is located in the first overlapping area A1 , and for the end point E1 of the linear track 151 , It is located in the first overlapping area A1, in the isosceles triangle area IT1 corresponding to the smallest of the four moving distances (moving distance d3), and in the second largest corresponding to the four moving distances (moving distance d2). ) within the first right-angled triangle region RT1, and within the second overlapping region A2. Furthermore, for the end point E2 of the linear track 151, it is located in the first overlapping area A1, located in the isosceles triangle area IT2 corresponding to the second largest of the four moving distances (the moving distance d2), and located in the isosceles triangle area IT2. Corresponding to the smallest of the four moving distances (moving distance d3 ) in the second right triangle area RT3 and outside the second overlapping area A2 .

5A to 5C are schematic diagrams illustrating the design flow of the curved track. First of all, please refer to FIG. 5A and compare with FIG. 2 , after the aforementioned linear track 151 has been obtained, then it can be located on the aforementioned linear reference line L1 , especially from the end point E1 of the linear track 151 (that is, the aforementioned position P1 ) to Take a plurality of points (eg, take N points) between the height H1 of the first right-angled triangle region RT1, and let these points follow the body 143 of the screen 140 in the first state (0 degree) and the second state (90 degrees) Rotate between, and select M positions at fixed intervals during the rotation, thereby generating multiple curves (N curves) and N*M reference points (M reference points on each curve), for example , if points are taken every 10 degrees between the first state (0 degrees) and the second state (90 degrees), then M=10.

Here, the selected points represent the turning point E5 of the curved track 152, that is, when the body 143 of the screen 140 is in the third state (45 degrees) (between the first state and the second state), The second guide pin 142 is moving to the position of the turning point E5. The interval selected here, that is, between the end point E1 of the linear track 151 and the height of the first right-angled triangle region RT1, is precisely to avoid the designed curved track 152 and the aforementioned linear track 151 from interfering, colliding, and intersecting with each other. Meanwhile, the M reference points of each of the aforementioned curves need to be located in the first right-angled triangle region RT1.

Please refer to FIG. 5A and FIG. 5B at the same time, calculate the average curvature of the above-mentioned curves, and select the one with the smallest average curvature as the curve track of this embodiment, and as shown in FIG. 5B , the curves passing through the positions P4 to P6 are the above-mentioned curves The point with the smallest average curvature among them, the point at the position P4 represents the turning point of the curved track 152, the point at the position P6 is the point at the aforementioned position P4 when the body 143 of the screen 140 rotates to 0 degrees (the first state), and the point at the position P6 The point of P5 is the point of the aforementioned position P4 which rotates to 90 degrees with the main body 143 of the screen 140 (the second state). Similar to the above, the number of these points is not limited here, and can be adjusted according to the relevant capabilities of the computer.

Based on the above, please refer to FIG. 5B and compare with FIG. 2 , the curved track 152 obtained in this embodiment obviously has the following characteristics: the curved track 152 is located in the first overlapping area A1, and the end point E3 of the curved track (equivalent to the position P5 point) and the turning point E5 (the point corresponding to the position P4) are located in the isosceles triangle area IT1, the inflection point E5 of the curved track is also located in the right triangle area RT1, and the endpoint E3 and the turning point E5 of the curved track 152 are located in the second overlapping area Inside A2, and the end point E4 is outside the second overlapping area A2.

Please refer to FIG. 5C and compare with FIG. 2 , since the curved track 152 is further known on the premise that the linear track 151 has been obtained, it also has the following characteristics: the turning point E5 of the curved track 152 is collinear with the linear track 151 (that is, the end The point E1, the end point E2 and the turning point E5 are collinear) and adjacent to the end point E1 of the linear track 151 (away from the end point E2), the turning point E5 of the curved track is located between the end points E3 and E4, and the turning point E5 to the end point E2. The relative distance d7 is equal to the relative distance d8 from the end point E4 to the end point E1, and is also equal to the relative distance d9 from the end point E3 to the end point E1. Accordingly, during the transition of the screen 140 from the first state to the second state, the second guide pin 142 moves from the end point E3 to the turning point E5, and then moves from the turning point E5 to the end point E4, and corresponds to the first guide pin 141 strokes (end point E1 moved to end point E2 and then moved back to end point E1).

FIG. 6A to FIG. 6C are schematic diagrams showing the design flow of the wiring area. Please refer to FIGS. 6A to 6C and compare FIG. 2 at the same time. In the present embodiment, after the above-mentioned design of the linear track and the curved track is completed, the wiring area 154 of the backplane 150 can be further designed accordingly, as shown in the following figure: As shown in FIGS. 1A and 1B , one end of the cable 160 is electrically connected to the screen 140 , and the other end is passed through the wiring area 154 until it is electrically connected to the computer motherboard 130 in the base 110 .

In detail, referring first to FIG. 6A and in contrast to FIG. 2 , the backplane 150 has a first reference line L3 passing through the end point E3 of the curved track 152 and parallel to the linear track 151 . The back plate 150 also has a second reference line L2 passing through the end point E4 of the curved track 152 and parallel to the linear track 151 . Next, take a plurality of points in the area surrounded by the second reference line L2, the hypotenuse H2 of the first right-angled triangle region RT1, the first reference line L3 and the curved track 152, and use it as the screen 140 in the first state ( 0 degrees) reference point. Next, referring to FIG. 6B , the points taken in FIG. 6A are rotated with the screen 140 to obtain M positions of the reference point at the same interval angle, and the points of these M positions form candidate areas, as shown in FIG. 6B . shown, so the sum will get N areas. Finally, the smallest of these areas is selected, which is the optimized routing area 154, as shown in FIG. 6C.

Referring again to FIG. 6C and comparing with FIGS. 2 and 3B , the wiring area 154 obtained in this embodiment obviously has the following characteristics: the wiring area 154 does not overlap the linear track 151 and the curved track 152 , and the wiring area 154 is located in the first An overlapping area A1 is also located in the area surrounded by the first reference line L3 , the second reference line L2 and the curved track 152 , and does not exceed the edge of the backplane 150 . Furthermore, the curved track 152 can be further divided into a front section and a rear section, wherein the front section is from the end point E3 to the turning point E5, and the rear section is from the turning point E5 to the end point E4, so the routing area 154 is located at the first reference point.
