[0055] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and effects of a rotating shaft assembly according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs.

[0057] In related technologies, for some notebook computers with double rotating shafts, in order to achieve non-uniform rotation of the display end and the system end. The double rotating shafts will adopt a gear structure to achieve non-uniform rotation of the display end and the system end.

[0058] However, the inventors of the present application found that in a double-rotating shaft mechanism, one rotating shaft is connected to a large gear, and the other rotating shaft is connected to a small gear. The large gear and the small gear mesh to achieve non-equal-ratio rotation of the two rotating shafts, that is, the rotational speeds of the two rotating shafts are different. For such a gear mechanism that realizes non-equal-ratio rotation of two rotating shafts, the distance between the two rotating shafts has relatively strict requirements. Because it is necessary to ensure that the two gears are meshed, the distance between the two rotating shafts is fixed. However, if the distance between the two rotating shafts is increased, in order to continue to ensure the meshing of the two rotating shafts' gears, or to continue to ensure the original transmission ratio of the two rotating shafts, the diameters of the two gears will inevitably change. For example, the diameters of the gears on the two rotating shafts will increase together. For some electronic devices, it is required that the thickness of the system end or the display end be as thin as possible and remain unchanged. Therefore, the change in the diameters of the gears on the two rotating shafts will be restricted by the thickness of the system end or the display end, resulting in that the distance between the two rotating shafts cannot be changed arbitrarily.

[0059] The following specifically describes a specific solution of a rotating shaft assembly provided by the present invention with reference to the accompanying drawings.

[0060] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a rotating mechanism, which at least includes a rotating shaft assembly and a sliding member 3.

[0061] The rotating shaft assembly includes a first rotating shaft 1 and a second rotating shaft 2. A first guiding portion 12 is provided on the first rotating shaft 1, and a second guiding portion 22 is provided on the second rotating shaft 2.

[0062] The first guiding portion 12 and the second guiding portion 22 respectively extend along the axial direction of the corresponding rotating shaft. That is, the first guiding portion 12 extends along the axial direction of the first rotating shaft 1, and the second guiding portion 22 extends along the axial direction of the second rotating shaft 2. The first guiding portion 12 and the second guiding portion 22 have a relative first stroke. Herein, the first stroke can be understood as a section of area on the guiding portion. The distance or length of the first stroke on the first guiding portion 12 and the distance or length of the first stroke on the second guiding portion 22 may be equal or unequal.

[0063] The sliding member 3 is located between the first rotating shaft 1 and the second rotating shaft 2, and the sliding member 3 can move relative to the rotating shaft assembly.

[0064] As Figure 1 and Figure 5 shown, the sliding member 3 includes a third guiding portion 31 and a fourth guiding portion 32. The third guiding portion 31 corresponds to the first guiding portion 12, and the fourth guiding portion 32 corresponds to the second guiding portion 22. During the process of the sliding member 3 moving along the first stroke, the third guiding portion 31 and the fourth guiding portion 32 respectively slide along the corresponding guiding portion, and cause the first rotating shaft 1 and the second rotating shaft 2 to rotate together.

[0065] The rotation angle of the first rotating shaft 1 is not equal to the rotation angle of the second rotating shaft 2. Among them, the rotation angle of the first rotating shaft 1 can be greater than the rotation angle of the second rotating shaft 2, or the rotation angle of the first rotating shaft 1 can be less than the rotation angle of the second rotating shaft 2.

[0066] In the rotating shaft mechanism of this embodiment, the sliding member 3 is respectively slidably matched with the guiding portions on the two rotating shafts to realize the non-uniform ratio rotation of the two rotating shafts. Since the sliding member 3 only slidably matches with the guiding portion on the rotating shaft through the guiding portion thereon, the distance between the two rotating shafts can be adjusted arbitrarily. Compared with realizing the non-uniform ratio rotation of the two rotating shafts through gear transmission, the change in the distance between the two rotating shafts does not affect the dimension of the sliding member in the axial direction perpendicular to the rotating shaft, as long as the guiding portion of the sliding member 3 is slidably matched with the guiding portion on the rotating shaft. Therefore, when the rotating shaft mechanism is used on an electronic device, the adjustment of the distance between the two rotating shafts is not limited by the thickness of the device.

[0067] In this embodiment, the first rotating shaft 1 and the second rotating shaft 2 are two independent rotating shafts and can be respectively connected to different bodies. Among them, the first rotating shaft 1 and the second rotating shaft 2 can be arranged in parallel or at an angle, as long as it is ensured that the two can rotate independently.

[0068] In some embodiments, during the process of the sliding member 3 moving along the first stroke, the rotation angle of the first rotating shaft 1 can be the first angle, and the rotation angle of the second rotating shaft 2 can be the second angle.

[0069] Furthermore, the first guiding portion 12 on the first rotating shaft 1 and the second guiding portion 22 on the second rotating shaft 2 also have a relative second stroke.

[0070] When the sliding member 3 moves along the second stroke, the first rotating shaft 1 can rotate the second angle, and the second rotating shaft 2 can rotate the first angle. This structure can enable the two rotating shafts to rotate the same angle.

[0071] Among them, the first angle can be greater than 90 degrees and less than 180 degrees, the second angle can be less than 90 degrees, and the sum of the first angle and the second angle is equal to 180 degrees. In this way, the two rotating shafts can respectively rotate 180 degrees, and rotate a total of 360 degrees, thereby increasing the rotation angle range of the two rotating shafts.

[0072] Of course, in some other embodiments, the sum of the first angle by which the first rotating shaft 1 rotates and the second angle by which the second rotating shaft 2 rotates may not necessarily reach 180 degrees. For example, the angles by which the first rotating shaft 1 and the second rotating shaft 2 rotate may be less than 90 degrees respectively, or may be greater than 90 degrees and less than 180 degrees respectively, or, the angle by which one rotating shaft rotates is less than 90 degrees, and the angle by which the other rotating shaft rotates is greater than 90 degrees and less than 180 degrees. As long as it is ensured that the angles by which the two rotating shafts rotate are different.

[0073] As Figure 2 , Figure 3 and Figure 4 shown, in some embodiments, the first guiding portion 12 may include a first spiral groove, and the second guiding portion 22 may include a second spiral groove. The two spiral grooves may extend around the axial direction of the corresponding rotating shaft. The third guiding portion 31 on the sliding member 3 extends into the first spiral groove and can slide along the first spiral groove; the fourth guiding portion 32 on the sliding member 3 extends into the second spiral groove and can slide along the second spiral groove.

[0074] The pitch of the first spiral groove may increase along a first direction, and the pitch of the second spiral groove may increase along a second direction, and the first direction and the second direction are opposite. Among them, the first direction may be the direction indicated by the arrow on the side of the first rotating shaft 1 in Figure 2 , and the second direction may be the direction indicated by the arrow on the side of the second rotating shaft 2 in Figure 2 . In addition, the increase in pitch can be understood as the distance between two adjacent threads of the spiral groove in the front is greater than the distance between two adjacent threads in the back along the first direction or the second direction.

[0075] The maximum pitch of the first spiral groove within the first stroke is less than the minimum pitch of the second spiral groove within the first stroke. In this way, when the sliding member 3 moves relative to the rotating shaft assembly along the first stroke, since the pitch of the second spiral groove is always greater than the pitch of the first spiral groove, the rotating speed of the first rotating shaft 1 will be greater than the rotating speed of the second rotating shaft 2. Therefore, the angle by which the first rotating shaft 1 rotates will be greater than the angle by which the second rotating shaft 2 rotates.

[0076] The minimum pitch of the first spiral groove within the second stroke is greater than the maximum pitch of the second spiral groove within the second stroke. In this way, when the sliding member 3 moves relative to the rotating shaft assembly along the second stroke, since the pitch of the second spiral groove is always less than the pitch of the first spiral groove, the rotating speed of the first rotating shaft 1 will be less than the rotating speed of the second rotating shaft 2. Therefore, the angle by which the first rotating shaft 1 rotates will be less than the angle by which the second rotating shaft 2 rotates.

[0077] It should be noted that the first helical groove and the second helical groove in this embodiment can be complete helical grooves or incomplete helical grooves. Among them, a complete helical groove can be understood as a helical groove that at least surrounds the rotating shaft for one circle. And an incomplete helical groove can be understood as a helical groove that does not surround the rotating shaft for one circle.

[0078] Since the sliding member 3 drives the two rotating shafts to rotate by sliding the two guiding portions thereon in the corresponding sliding grooves on the two rotating shafts during the movement process. Therefore, when both the first helical groove and the second helical groove are complete helical grooves, the maximum rotation angle of the two rotating shafts can be increased. For example, the two rotating shafts can rotate 360 degrees or 720 degrees respectively.

[0079] When both the first helical groove and the second helical groove are incomplete helical grooves, the pitch can be understood as the distance between two regions on the helical groove that are close to each other in the axial direction of the rotating shaft. Then, by controlling the lengths of the two incomplete helical grooves in the axial direction of the rotating shaft, the maximum rotation angle of the two rotating shafts can be controlled. For example, the first rotating shaft 1 and the second rotating shaft 2 can rotate 90 degrees, 120 degrees or 180 degrees respectively.

[0080] In addition, in this embodiment, the first helical groove and the second helical groove can be single helical grooves or multi-helical grooves. The number of guiding portions on the sliding member 3 is the same as the number of corresponding helical grooves, that is, each guiding portion on the sliding member 3 corresponds to a helical groove respectively.

[0081] In some embodiments, the helix directions of the first helical groove and the second helical groove can be the same or different. When the helix directions of the two helical grooves are the same, the first rotating shaft 1 and the second rotating shaft 2 rotate in the same direction during the movement of the sliding member 3; when the helix directions of the two helical grooves are opposite, the rotation direction of the first rotating shaft 1 is opposite to the rotation direction of the second rotating shaft 2 during the movement of the sliding member 3.

[0082] In some embodiments, the pitch of the first helical groove on the first rotating shaft 1 increases proportionally along the first direction, and the pitch of the second helical groove on the second rotating shaft 2 increases proportionally along the second direction. In this way, during the movement of the sliding member 3, the ratio of the rotation angle of the first rotating shaft 1 to the rotation angle of the second rotating shaft 2 can be a fixed value, so as to better control the rotation of the two rotating shafts.

[0083] Among them, the value of the proportional increase in the pitch of the first helical groove and the value of the proportional increase in the pitch of the second helical groove can be equal or not equal. By adjusting the pitches of the two helical grooves, the ratio of the rotation angles of the two rotating shafts can be conveniently adjusted.

[0084] In some embodiments, the first stroke and the second stroke of the two guiding portions may be adjacent. Adjacency can be understood as that the end of the first stroke and the beginning of the second stroke can be directly connected end to end, or the end of the first stroke and the beginning of the second stroke can be connected through a third stroke.

[0085] When the end of the first stroke and the beginning of the second stroke are connected end to end, the sliding member 3 can immediately slide along the second stroke after sliding along the first stroke, thereby realizing a rapid switching of the rotational speed of the rotating shaft.

[0086] Alternatively, the two guiding portions may further respectively include a third stroke, and the third stroke connects the end of the first stroke and the beginning of the second stroke. When the sliding member 3 moves along the third stroke, the states of the two rotating shafts are not specifically limited. For example, the first rotating shaft 1 and the second rotating shaft 2 may not rotate. That is, after the sliding member 3 moves from the first stroke to the third stroke, the first rotating shaft 1 and the second rotating shaft 2 may not rotate differently. Or, at least one of the two rotating shafts continues to rotate.

[0087] In some embodiments, the length of the first stroke of the first helical groove on the first rotating shaft 1 is equal to the length of the first stroke of the second helical groove on the second rotating shaft 2. The length of the second stroke of the first helical groove is equal to the length of the second stroke of the second helical groove. In this way, during the movement of the sliding member 3 along the first stroke or the second stroke, the two rotating shafts can rotate synchronously and by equal angles.

[0088] In some embodiments, a first guide wheel portion 11 is provided on the first rotating shaft 1, and the first helical groove may be formed on the outer peripheral surface of the first guide wheel portion 11. A second guide wheel portion 21 opposite to the first guide wheel portion 11 is provided on the second rotating shaft 2, and the second helical groove may be formed on the second guide wheel portion 21.

[0089] Among them, the structure of the guide wheel portion is not specifically limited. By way of example, as Figure 3 and Figure 4 shown, the guide wheel portion may be a shaft structure and is coaxially arranged with the rotating shaft.

[0090] In some embodiments, corresponding helical grooves may be machined on the outer peripheral walls of the two guide wheel portions, which can further reduce the radial distance between the two rotating shafts.

[0091] Alternatively, in some other embodiments, two helical rib plates may be arranged at intervals on the outer peripheral wall of the guide wheel portion, and a helical groove is formed between the two helical rib plates. As for the connection manner between the helical rib plate and the guide wheel portion, it is not specifically limited.

[0092] The two guide wheel portions may be an integral structure with the rotating shaft, thereby omitting the assembly process and facilitating processing. Or, the two guide wheel portions may also be sleeve structures, sleeved on the corresponding rotating shafts, and the helical grooves are provided on the outer peripheral surfaces of the guide wheel portions.

[0093] In some embodiments, the shaft diameter of the first rotating shaft 1 and the shaft diameter of the second rotating shaft 2 may be different. The diameters of the two rotating shafts can be determined according to the bodies they are respectively connected to. For example, when the rotating mechanism is used in a laptop computer, the system end is connected to the first rotating shaft 1 and the display end is connected to the second rotating shaft 2. The display end is thinner, so the second rotating shaft 2 can be thin; the system end is thicker, so the first rotating shaft 1 can be thick.

[0094] In some embodiments, the depth of the first helical groove on the first rotating shaft 1 and the depth of the second helical groove on the second rotating shaft 2 may be different. When the shaft diameter of one of the two rotating shafts is larger than that of the other rotating shaft, the depth of the helical groove on the rotating shaft with a larger shaft diameter can be greater than the depth of the helical groove on the rotating shaft with a smaller shaft diameter, so as to ensure that the strengths of the two rotating shafts meet the requirements.

[0095] In some embodiments, the rotating mechanism may further include a limiting member. The limiting member is located on both sides of the moving direction of the sliding member 3 and is movably connected to the sliding member 3 to limit the sliding member 3 from rotating synchronously with the first rotating shaft 1 and the second rotating shaft 2, so as to ensure that the two rotating shafts can rotate independently.

[0096] As for the structure, position and shape of the limiting member, the present application does not make specific limitations.

[0097] The limiting member may be formed on the connecting component 4 connecting the two rotating shafts. The connecting component 4 is rotatably connected to the rotating shaft. The connecting component 4 is provided with through holes for the first rotating shaft 1 and the second rotating shaft 2 to pass through. The two rotating shafts can be in clearance fit with the connecting component 4 respectively. The connecting component 4 only serves to connect the two rotating shafts and cannot rotate synchronously with the rotating shafts.

[0098] Exemplarily, as Figure 1 and Figure 6 shown, the connecting component 4 includes a first connecting frame 41 and a second connecting frame 42 for connecting the two rotating shafts. The first connecting frame 41 and the second connecting frame 42 respectively have guide plates 43 located on both sides of the sliding member 3. The guide plates 43 form the limiting member. The sliding member 3 can be slidably connected to the guide plates 43 respectively. During the process of the sliding member 3 moving along the rotating shaft assembly, the guide plates 43 on both sides can limit the sliding member 3 from rotating with the two rotating shafts.

[0099] In some embodiments, the guide plate 43 and the sliding member 3 can be matched through a guide groove and a guide block. The extending direction of the guide groove is consistent with the moving direction of the sliding member 3. The guide block is slidably connected to the guide groove and can slide along the guide groove.

[0100] Among them, the guide groove can be arranged on the guide plate 43, and the guide block is arranged on the sliding member 3. Or, the guide groove can be arranged on the sliding member 3, and the guide block can be arranged on the guide plate 43.

[0101] An embodiment of the present application further provides an electronic device, such as Figure 7 and Figure 12 As shown, the electronic device may include a rotating mechanism, a connecting component 4, a first body 7 (not shown in the figure), and a second body 8 (not shown in the figure).

[0102] Among them, the rotating mechanism includes a rotating shaft assembly and a sliding member 3. The rotating shaft assembly includes a first rotating shaft 1 and a second rotating shaft 2. A first guiding portion 12 is provided on the first rotating shaft 1, and a second guiding portion 22 is provided on the second rotating shaft 2. The first guiding portion 12 and the second guiding portion 22 extend along the axial directions of the corresponding rotating shafts respectively, and the first guiding portion 12 and the second guiding portion 22 have a relative first stroke.

[0103] The sliding member 3 is located between the first rotating shaft 1 and the second rotating shaft 2. The sliding member 3 can move relative to the rotating shaft assembly. The sliding member 3 includes a third guiding portion 31 and a fourth guiding portion 32. The third guiding portion 31 corresponds to the first guiding portion 12, and the fourth guiding portion 32 corresponds to the second guiding portion 22.

[0104] During the process of the sliding member 3 moving along the first stroke, the third guiding portion 31 and the fourth guiding portion 32 slide along the corresponding guiding portions respectively, and cause the first rotating shaft 1 and the second rotating shaft 2 to rotate together. The rotation angle of the first rotating shaft 1 is not equal to the rotation angle of the second rotating shaft 2;

[0105] The first body 7 is connected to the first rotating shaft 1 and can rotate synchronously with the first rotating shaft 1; the second body 8 is connected to the second rotating shaft 2 and can rotate synchronously with the second rotating shaft 2.

[0106] The connecting component 4 connects the first rotating shaft 1 and the second rotating shaft 2. The first rotating shaft 1 and the second rotating shaft 2 are respectively rotatably connected to the connecting component 4 and can respectively rotate relative to the connecting component 4. The connecting component 4 is used to ensure that the radial distance between the two rotating shafts remains unchanged during the respective rotations of the two rotating shafts, that is, to ensure that the two rotating shafts do not separate or approach each other.

[0107] Among them, the electronic device may be an electronic device such as a notebook computer or a mobile phone. Specifically, when the electronic device is a notebook computer, among the two bodies, one body may be the screen end and the other body may be the system end; when the electronic device is a mobile phone, the mobile phone may be a folding screen, such as a double-fold screen or a triple-fold screen, and the first body 7 and the second body 8 are two adjacent screens.

[0108] In one of the two bodies of the electronic device in this embodiment, one body is connected to the first rotating shaft 1, and the other body is connected to the second rotating shaft 2. Through the rotating mechanism, non-proportional rotation of the first body 7 and the second body 8 can be achieved.

[0109] In this embodiment, the electronic device can be placed on a shelving surface such as a desktop for use. Among them, the body connected to the one with a larger rotation angle among the two rotating shafts can be placed on the desktop, and the other body can rotate relative to the body placed on the desktop. In this embodiment, the first body 7 is taken as the system end and the second body 8 is taken as the display end for illustration.

[0110] As Figure 7 shown, in some embodiments, a first connecting plate 5 can be connected to the first rotating shaft 1, and the first connecting plate 5 can be used to connect the system end. A second connecting plate 6 can be connected to the second rotating shaft 2, and the second connecting plate 6 can be connected to the display end.

[0111] In some embodiments, during the process of the sliding member 3 moving along the first stroke, the rotation angle of the first rotating shaft connected to the first body 7 is greater than the rotation angle of the second rotating shaft connected to the second body 8.

[0112] The sliding member 3 has a first moving area, a second moving area, and a third moving area in the direction of the first stroke.

[0113] When the sliding member moves within the first moving area, in the direction perpendicular to the shelving surface, the difference between the distance L1 between the second rotating shaft and the shelving surface and the distance L2 between the first rotating shaft and the shelving surface is greater than 10 cm.

[0114] When the sliding member is in the second moving area, in the direction perpendicular to the shelving surface, the difference L2 between the distance L1 between the second rotating shaft and the shelving surface and the first rotating shaft and the shelving surface is less than 10 cm and greater than -10 cm.

[0115] When the sliding member moves within the third moving area, in the direction perpendicular to the shelving surface, the difference L2 between the distance L1 between the second rotating shaft and the shelving surface and the distance L2 between the first rotating shaft and the shelving surface is less than -10 cm.

[0116] When the sliding member moves within the second moving area and the third moving area within the first stroke, this structure can enable the display end to sink during the process of rotating relative to the system end, thereby increasing the visual screen ratio. Among them, when the sliding member moves within the second moving area and the third moving area within the first stroke, the included angle between the display end and the system end is an obtuse angle, which can be at least greater than 110 degrees, so as to achieve the effect of increasing the visual screen ratio. See Figure 8 shown.

[0117] In some embodiments, during the process of the sliding member 3 moving along the first stroke, the rotation angle of the first rotating shaft 1 can be the first angle, and the rotation angle of the second rotating shaft 2 can be the second angle. Among them, the ratio of the first angle to the second angle can be 3:1. In this way, when the included angle between the display end and the system end is 110 degrees, the effect of the display end sinking can be achieved.

[0118] Of course, in the actual application process, it is also possible to achieve the effect of the display end sinking when the included angle between the display end and the system end is other angles. For example, 100 degrees, 105 degrees, 115 degrees, or 125 degrees, etc. Correspondingly, the included angle between the display end and the system end when the display end sinks can be changed by changing the ratio of the first angle to the second angle. For example, when both the first guiding portion 12 and the second guiding portion 22 are spiral grooves, the ratio of the first angle to the second angle can be changed by the pitch of the spiral grooves.

[0119] In some embodiments, the first guiding portion 12 and the second guiding portion 22 further have a relative second stroke. When the sliding member 3 moves along the second stroke, the first rotating shaft 1 can rotate by a second angle, and the second rotating shaft 2 can rotate by a first angle.

[0120] Wherein, the first angle can be greater than 90 degrees and less than 180 degrees, the second angle can be less than 90 degrees, and the sum of the first angle and the second angle is equal to 180 degrees.

[0121] As Figure 3 and Figure 4 shown, in some embodiments, the first guiding portion 12 includes a first spiral groove, and the second guiding portion 22 includes a second spiral groove. The two spiral grooves can extend around the axial direction of the corresponding rotating shaft. The third guiding portion 31 on the sliding member 3 extends into the first spiral groove, and the fourth guiding portion 32 on the sliding member 3 extends into the second spiral groove.

[0122] The pitch of the first spiral groove increases along a first direction, and the pitch of the second spiral groove increases along a second direction, and the first direction and the second direction are opposite.

[0123] The maximum pitch of the first spiral groove within the first stroke is less than the minimum pitch of the second spiral groove within the first stroke. Thus, when the sliding member 3 moves relative to the rotating shaft assembly along the first stroke, since the pitch on the second spiral groove is always greater than the pitch of the first spiral groove, the rotation speed of the first rotating shaft 1 will be greater than the rotation speed of the second rotating shaft 2. Therefore, the rotation angle of the first rotating shaft 1 will be greater than the rotation angle of the second rotating shaft 2.

[0124] The minimum pitch of the first spiral groove within the second stroke is greater than the maximum pitch of the second spiral groove within the second stroke. Thus, when the sliding member 3 moves relative to the rotating shaft assembly along the second stroke, since the pitch on the second spiral groove is always less than the pitch of the second spiral groove, the rotation speed of the first rotating shaft 1 will be less than the rotation speed of the second rotating shaft 2. Therefore, the rotation angle of the first rotating shaft 1 will be less than the rotation angle of the second rotating shaft 2.

[0125] The use of spiral grooves not only enables non - proportional rotation of the two rotating shafts, but also the two guiding parts of the sliding member 3 are respectively embedded in the corresponding spiral grooves. When the sliding member 3 moves from the first stroke to the second stroke, the guiding parts of the sliding member 3 always move within the corresponding spiral grooves, so that there is no switching feel during the switching process of the two rotating shafts in the two strokes.

[0126] Exemplarily, Figures 8 to 10 It shows the rotation situation of the display end and the system end of the electronic device when the rotation angle ratio of the first rotating shaft 1 and the second rotating shaft 2 is 3, and the first guiding part 12 includes a first spiral groove and the second guiding part 22 includes a second spiral groove.

[0127] As Figures 8 to 9 shown, during the process of the display end rotating from 0 degrees to 180 degrees, the sliding member 3 slides along the first stroke. Since the pitch of the second spiral groove of the second rotating shaft 2 is always greater than the pitch of the first spiral groove on the first rotating shaft 1, when the sliding member 3 slides to the right, within the unit distance of movement of the sliding member 3, because the pitches of the spiral grooves on the upper and lower rotating shafts are different and the second spiral groove is always greater than the first spiral groove, the angle of rotation of the first rotating shaft 1 within the unit distance is greater than the angle of rotation of the second rotating shaft 2. Figure 9 It shows that during the process from 0 degrees to 180 degrees, the second rotating shaft 2 rotates 45 degrees and the first rotating shaft 1 rotates 135 degrees. At this time, the display end of the electronic device rotates 180 degrees in the overall machine form, and the effect of the display end sinking is achieved.

[0128] As Figures 9 to 10 shown, during the process of the display end rotating from 180 degrees to 360 degrees, the sliding member 3 slides along the second stroke. Since the pitch of the second spiral groove of the second rotating shaft 2 is always less than the pitch of the first spiral groove on the first rotating shaft 1, the sliding member 3 continues to slide to the right. Within the unit distance of movement of the sliding member 3, because the pitches of the two spiral grooves are different and the pitch of the second spiral groove is always less than the pitch of the first spiral groove, the angle of rotation of the first rotating shaft 1 within the unit distance is less than the angle of rotation of the second rotating shaft 2. Figure 10 It shows that during the process from 180 degrees to 360 degrees of the display end of the electronic device, the second rotating shaft 2 rotates 135 degrees and the first rotating shaft 1 rotates 45 degrees. At this time, the electronic device rotates 360 degrees in the overall machine form, and we achieve that within the 360 - degree cycle, the display end and the system end both rotate a total of 180 degrees, and the position of the camera of the whole machine can still be aligned in the 360 - degree state.

[0129] When the display end moves from 360 degrees to 0 degrees, the steps are opposite to the above process. In the above example, the screen end and the system end each rotate 180 degrees during the 360 - degree rotation process. In practice, the rotation angles of the screen side and the system side can be made different by adjusting the displacement length of the sliding member 3.
