Detailed Description
Illustrative embodiments of the present application include, but are not limited to, door panel lift assemblies, spindle mechanisms, and foldable electronic devices. The following describes in detail the embodiments of the present application with reference to the drawings.
Fig. 1 and 2 illustrate exemplary block diagrams of a foldable electronic device 10 provided in an embodiment of the present application. Fig. 1 is a schematic view of a foldable electronic device 10 in an unfolded state, and fig. 2 is a schematic view of the foldable electronic device 10 in a folded state.
In each of the drawings, the X direction is a longitudinal direction (as an example of the third direction) of the foldable electronic device 10, the Y direction is a width direction of the foldable electronic device 10, and also is an axial direction of the spindle mechanism (as an example of the first direction), and the Z direction is a thickness direction (as an example of the second direction) of the foldable electronic device 10. The X direction, the Y direction and the Z direction may be perpendicular to each other.
In the present embodiment, a cellular phone is taken as an example of the foldable electronic device 10. In other embodiments, the foldable electronic device 10 may be a notebook computer, a tablet, a large screen device, a vehicle-mounted device, a wearable device (e.g., a wristwatch, smart glasses, a helmet), an augmented Reality (Augmented Reality, AR)/Virtual Reality (VR) device, a personal digital assistant (Personal Digital Assistant, PDA), or any screen bendable device, and the application is not limited.
As shown in fig. 1 and 2, the foldable electronic device 10 includes a first housing 11, a second housing 12, a rotation shaft mechanism 13, and a flexible screen (not shown) that covers the first housing 11, the second housing 12, and the rotation shaft mechanism 13, the rotation shaft mechanism 13 being disposed between the first housing 11 and the second housing 12 and connected to the first housing 12 and the second housing 12, respectively. The hinge mechanism 13 is a key mechanism of the foldable electronic device 10, and is responsible for unfolding and folding the foldable electronic device 10. The first housing 11 and the second housing 12 can be relatively rotated about an axial direction (Y direction shown here) by a rotation shaft mechanism 13, so that the flexible screen is unfolded or folded.
As shown in fig. 1, when the foldable electronic device 10 is in an unfolded state, the first housing 11 and the second housing 12 are respectively located at two sides of the rotating shaft mechanism 13, and accordingly, the flexible screen is in an unfolded state. The rotation shaft mechanism 13 may include a first side door panel 131 and a second side door panel 132, and the first side door panel 131 may be connected to the first housing 11 for supporting a flexible screen (hereinafter, simply referred to as a first screen) covering the first housing 11. The second side door panel 132 may be connected to the second housing 12 for supporting a flexible screen (hereinafter referred to as a second screen) that covers the second housing 12.
As shown in fig. 2, when the foldable electronic device 10 is in a folded state, the first housing 11 and the second housing 12 are stacked relatively, and the first screen and the second screen are attached relatively. The spindle mechanism 13 may be in a drop shape, a U shape, or a bat shape when viewed from the side, and fig. 2 illustrates the drop shape as an example, and the shape of the spindle mechanism 13 is not limited by the present application. Wherein the drop-shaped hinge mechanism 13 helps to reduce the gap between the first and second panels after folding.
It should be noted that, the folding state of the foldable electronic device 10 provided in the embodiment of the present application is not limited to the internal folding manner shown in fig. 2, that is, the manner in which the folded flexible screen is located between the first housing 11 and the second housing 12, and may also be folded in a manner in which the folded flexible screen is exposed (i.e., an external folding manner).
With continued reference to fig. 1, the pivot mechanism 13 further includes an intermediate door panel 133, where the intermediate door panel 133 is disposed between the first side door panel 131 and the second side door panel 132. The intermediate door panel 133 is liftable in a second direction (Z direction as illustrated herein) and when the foldable electronic device 10 is unfolded, the intermediate door panel 133 is lifted for supporting the flexible screen and reducing the crease depth in the center of the flexible screen. When the foldable electronic device 10 is folded, the middle door panel 133 descends to provide a sufficient accommodation space for the bending portion of the flexible screen.
The intermediate door panel 133 requires additional parts to drive the intermediate door panel 133 up and down. In some embodiments, a part for lifting the middle door plate 133 is disposed along the axial direction of the rotating shaft mechanism 13, and the part moves along the axial direction to drive the middle door plate 133 to lift. However, in this manner, the number of parts to be provided is large, which not only increases the weight, but also is disadvantageous in light weight of the foldable electronic device 10, and occupies a large amount of axial space of the spindle mechanism 13, thereby limiting the design of other modules (e.g., a through-axis FPC, etc.) in the axial direction.
Based on this, the embodiment of the application provides a door plate lifting assembly, which is used for realizing the lifting of the middle door plate 133, so that the number of axial parts of the rotating shaft mechanism 13 can be reduced, and the axial space can be saved.
Fig. 3 and 4 are schematic structural views of a door panel lifting assembly 20 according to an embodiment of the present application. It will be appreciated that the relative positional relationship of the components of the door lift assembly 20 is continuously changed during the lifting of the intermediate door 133, and that fig. 3 and 4 respectively show two movement configurations of the door lift assembly 20, fig. 3 is a final movement configuration (hereinafter referred to as a first configuration) of the door lift assembly 20 when the intermediate door 133 is lifted to the highest position, and fig. 4 is a final movement configuration (hereinafter referred to as a second configuration) of the door lift assembly 20 when the intermediate door 133 is lowered to the lowest position.
As shown in fig. 3, the door panel lifting assembly 20 includes a first shaft 21, an intermediate door panel 133, a first link mechanism and a first driving mechanism. Wherein the axis of the first shaft 21 extends in a first direction (Y direction illustrated herein). The intermediate door panel 133 is spaced from the first shaft 21 along a second direction (Z direction as illustrated herein) that is perpendicular to the first direction. In some embodiments, the middle door panel 133 extends from one end of the flexible screen to the other end in the Y direction, and the length of the first shaft 21 in the Y direction may be greater than the length of the middle door panel 133, so that the first link mechanism and the first driving mechanism provided along the first shaft 21 may support the entire middle door panel 133, and promote stability of the middle door panel 133 when lifted.
The first link mechanism includes at least two sets of first links disposed at intervals along the Y direction, and one end of each set of first links is rotatably connected to the middle door panel 133. In some embodiments, as shown in fig. 3, the first linkage includes a first set of first links 22 and a second set of first links 22', and the first set of first links 22 and the second set of first links 22' may be symmetrical with respect to a first plane (P1 plane illustrated herein), the P1 plane being perpendicular to the Y direction. For example, the first set of first links 22 and the second set of first links 22' may be disposed opposite each other in a straight figure eight.
The first driving mechanism is arranged on the first shaft 21, and comprises at least two first driving parts, and the at least two first driving parts are in one-to-one correspondence with the at least two first connecting rods. In some embodiments, as shown in fig. 3, at least two first driving parts include a driving part 23 (as an example of a first driving part) corresponding to the first group of first links 22, and a driving part 23 '(as an example of a first driving part) corresponding to the second group of first links 22'.
The driving process of the link by the driving section is described by taking the driving section 23 as an example. The driving section 23 includes a rotating member 231 (as an example of a first rotating member) and a sliding member 232 (as an example of a first sliding member). When the foldable electronic device 10 is folded or unfolded, the first housing 11 of the foldable electronic device 10 drives the rotating member 231 to rotate, so that the rotating member 231 rotates around the axis of the first shaft 21 relative to the first shaft 21, and the sliding member 232 can be driven to slide along the Y direction relative to the first shaft 21 when the rotating member 231 rotates. In some embodiments, the rotating member 231 may be connected to the first housing 11, so that when the foldable electronic device 10 is folded or unfolded, the first housing 11 can drive the rotating member 231 to rotate around the axis of the first shaft 21, so that the sliding member 232 slides along the Y direction relative to the first shaft 21. One end of the first link 22 is rotatably connected to the intermediate door plate 133, and the other end of the first link 22 is rotatably connected to the slider 232 of the corresponding driving unit 23. In this way, when the sliding member 232 slides along the Y direction, the first link 22 can drive the middle door panel 133 to lift along the Z direction.
The driving part 23 'may be configured by referring to the driving part 23, in which the rotation member 231' (as an example of the first rotation member) in the driving part 23 'may rotate around the axis with respect to the first shaft 21, and the rotation member 231' may drive the sliding member 232 '(as an example of the first sliding member) in the driving part 23' to slide in the Y direction with respect to the first shaft 21 when rotated, and the sliding member 232 'may drive the intermediate door plate 133 to move up and down in the Z direction by the second group of the first connecting rods 22' when slid in the Y direction.
Illustratively, the first rotating members in the different first driving portions are synchronously rotated, that is, the driving portions 23 and 23 'can simultaneously drive the corresponding first group of first links 22 and the corresponding second group of first links 23' to synchronously lift the middle door panel 133 along the Z direction. That is, under the driving action of the driving part 23 and the driving part 23', the connection ends of the first group of first links 22 and the middle door panel 133, and the lifting amount of the connection ends of the second group of first links 23' and the middle door panel 133 are the same, so that the middle door panel 133 can maintain the posture unchanged (e.g., always parallel to the X-Y plane) during the lifting.
Referring to fig. 3, when the first set of first links 22 and the second set of first links 22 'are disposed opposite to each other in a splayed manner, the sliding members 232 and 232' slide toward two ends of the first shaft 21 respectively under the driving of the driving portions 23 and 23 'during the folding process of the foldable electronic device 10, so that the first set of first links 22 and the second set of first links 22' drive the middle door panel 133 to descend.
For ease of understanding, how the first slider and the first link cooperate to effect lifting of the intermediate door panel 133 is described below in conjunction with two motion schematics. Fig. 5A is a motion diagram of the state shown in fig. 3, fig. 5B is a motion diagram of the state shown in fig. 4, fig. 5A to 5B show that the middle door panel 133 is in a lowering process, that is, the foldable electronic device 10 is in a folding process, and fig. 5B to 5A show that the middle door panel 133 is in a lifting process, that is, the foldable electronic device 10 is in an unfolding process.
Take the descent process of fig. 5A to 5B as an example. In the folding process (for example, when the user folds the first housing 11 and the second housing 12 of the electronic device 10 in opposite directions), the first housing 11 drives the rotating member 231 and the rotating member 231' to rotate around the axis of the first shaft 21, and when the rotating member 231 and the rotating member 231' rotate, the sliding member 232 and the sliding member 232' are respectively driven to slide toward the two ends of the first shaft 21, that is, when the rotating member 231 rotates, the sliding member 232 is driven to slide toward the left side in the drawing, and when the rotating member 231' rotates, the sliding member 232' is driven to slide toward the right side in the drawing. When the foldable electronic device 10 is in the folded state, the middle door panel 133 is lowered to the lowest position (the position shown in fig. 5B).
In some embodiments, as shown in fig. 5C, the first set of first links 22 and the second set of first links 22 'may be disposed opposite to each other in a reverse splayed shape, and then, during the folding process, the foldable electronic device 10 is driven by the driving portion 23 and the driving portion 23', and the sliding member 232 'slide relatively on the first shaft 21, so that the first set of first links 22 and the second set of first links 22' drive the middle door plate 133 to descend.
In some embodiments, as shown in fig. 5D and 5E, the first set of first links 22 and the second set of first links 22' may also be parallel to each other, which is not limited by the present application.
In some embodiments, any two first links in the first linkage may be arranged in the manner described above with reference to the first set of first links 22 and the second set of first links 22'. For example, the first linkage includes three sets of first links, wherein the first set of first links is disposed opposite the second set of first links in a positive splayed orientation, and the second set of first links and the third set of first links are disposed opposite the first links in an inverted splayed orientation. For another example, the first link mechanism includes four groups of first links, wherein two groups of first links are arranged opposite to each other in a positive figure, and the other two groups of first links are arranged opposite to each other in a positive figure.
In some embodiments, each group of the first connecting rods in the first connecting rod mechanism may be formed by one connecting rod, or may be formed by sequentially connecting a plurality of connecting rods. Each group of first connecting rods is composed of one connecting rod, so that the complexity of parts can be reduced, the overall weight of the assembly is reduced, and the lifting stability of the middle door plate 133 is improved. Each group of first connecting rods is composed of a plurality of connecting rods, so that the lifting flexibility of the middle door plate 133 can be improved, and the middle door plate 133 can hover at different lifting heights.
As shown in fig. 6-10B, in some embodiments, the door panel lift assembly 20 further includes a second shaft 24, a second linkage, and a second drive mechanism. Wherein fig. 6 is a top view of door panel lift assembly 20 in a first configuration. Fig. 7A and 7B are perspective views of the door panel lift assembly 20 from different perspectives in the first configuration. Fig. 8 is a side view of door panel lift assembly 20 in a first configuration. Fig. 9 is a top view of door panel lift assembly 20 in a second configuration. Fig. 10A and 10B are perspective views of the door panel lift assembly 20 in a second configuration at a different perspective.
Wherein the second shaft 24 is spaced from the first shaft 21 along the X-direction. In some embodiments, the second axis 24 is the same length as the first axis 21 in the Y-direction.
The second linkage mechanism includes at least two sets of second links, one end of each set of second links being rotatably connected to the intermediate door panel 133. In some embodiments, at least two sets of second links are in one-to-one correspondence with at least two sets of first links, the first and second links corresponding to each other being symmetrical about a second plane, the second plane being located between the first and second axes 21, 24 and perpendicular to the X-direction. As shown in fig. 7A and 7B, the second link mechanism includes a first group of second links 25 and a second group of second links 25', the first group of second links 25 corresponding to the first group of first links 22, and the second group of second links 25' corresponding to the second group of first links 22 '. It will be appreciated that the first set of second links 25 and the second set of second links 25' are symmetrical with respect to the plane P1. The first set of second links 25 and the second set of second links 25' may be disposed opposite each other in a straight figure eight. As shown in fig. 8, the first set of second links 25 may be symmetrical with respect to the first set of first links 22 with respect to a second plane (herein each illustrates a P2 plane).
The second driving mechanism is disposed on the second shaft 24, and the second driving mechanism includes at least two second driving portions, where the at least two second driving portions are in one-to-one correspondence with the at least two groups of second connecting rods. In some embodiments, the at least two second driving parts are in one-to-one correspondence with the at least two first driving parts, and the first driving parts and the second driving parts corresponding to each other are symmetrical about the second plane. As shown in fig. 6, the second driving mechanism includes a driving portion 26 (as an example of a second driving portion) and a driving portion 26' (as an example of a second driving portion), the driving portion 26 and the driving portion 23 are symmetrical about the P2 plane, and the driving portion 26' and the driving portion 23' are symmetrical about the P2 plane. As shown in fig. 7B, the driving portion 26 corresponds to the first group of second links 25, and the driving portion 26 'corresponds to the second group of second links 25'.
As shown in fig. 7B, taking the driving portion 26 as an example, the driving portion 26 includes a rotating member 261 (as an example of a second rotating member) and a sliding member 262 (as an example of a second sliding member), when the foldable electronic device 10 is folded or unfolded, the second housing 12 drives the rotating member 261 to rotate, so that the rotating member 261 rotates around the axis of the second shaft 24 with respect to the second shaft 24, and when the rotating member 261 rotates, the sliding member 262 can be driven to slide along the Y direction with respect to the second shaft 24. In some embodiments, the rotating member 231 may be connected to the first housing 11, and the rotating member 261 may be connected to the second housing 12, so that when the foldable electronic device 10 is folded or unfolded, the first housing 11 can drive the rotating member 231 to rotate around the axis of the first shaft 21, such that the sliding member 232 slides along the Y direction relative to the first shaft 21, and the second housing 12 can drive the rotating member 261 to rotate around the axis of the second shaft 24, such that the sliding member 262 slides along the Y direction relative to the second shaft 24.
One end of the second link 25 is rotatably connected to the middle door plate 133, and the other end of the second link 25 is rotatably connected to the slider 262 of the corresponding driving part 26, so that the slider 262 can drive the middle door plate 133 to lift in the second direction through the second link 25 when sliding in the Y direction.
The structure of the driving portion 26' may refer to the structure of the driving portion 26, and will not be described herein.
It can be appreciated that when the first set of second links 25 and the second set of second links 25' are disposed opposite to each other in a positive figure, during the folding process of the foldable electronic device 10, under the driving of the driving portion 26 and the driving portion 26', the sliding members 262 and 262' (not shown) in the driving portion 26' slide on two ends of the second shaft 24, so that the first set of second links 25 and the second set of second links 26' drive the middle door panel 133 to descend.
In some embodiments, as shown in fig. 8, the first link 22 and the second link 25 are located between the first shaft 21 and the second shaft 24 in the X direction. In this way, the lifting of the middle door panel 133 can be achieved by fully utilizing the space in the shaft between the first shaft 21 and the second shaft 24, and a large amount of axial space can be saved without arranging too many parts along the axial direction.
In some embodiments, the second rotating member in each second driving portion rotates synchronously with the first rotating member in the corresponding first driving portion, so as to drive the first sliding member and the second sliding member to slide along the Y direction relative to the first shaft and the second shaft, and when the first sliding member and the second sliding member slide along the Y direction, the door panel can be driven by the first connecting rod and the second connecting rod to lift along the second direction. It will be appreciated that the first rotating member in the different first driving portion and the second rotating member in the different second driving portion rotate synchronously, that is, the driving portion 23', the driving portion 26, and the driving portion 26' can simultaneously drive the first set of first connecting rods 22, the second set of first connecting rods 23', the first set of second connecting rods 25, and the second set of second connecting rods 25' respectively corresponding to each other to drive the middle door panel 133 to lift in the Z direction.
Referring to fig. 7A, 7B, 10A and 10B, the intermediate door panel 133 is shown in a lowering process by fig. 7A to 10A or fig. 7B to 10B, i.e., the foldable electronic device 10 is in a folding process. Fig. 10A to 7A or fig. 10B to 7B illustrate the middle door panel 133 in a lifting process, i.e., the foldable electronic device 10 in a unfolding process. Taking the lowering process of fig. 7A to 10A and fig. 7B to 10B as an example, the first housing 11 drives the rotating member 231 and the rotating member 231 'to rotate about the axis of the first shaft 21 and the second housing 12 drives the rotating member 261 and the rotating member 261' to rotate about the axis of the second shaft 24 during the folding process of the foldable electronic device 10. When the rotating member 231 and the rotating member 231 'rotate, the sliding member 232 and the sliding member 232' are driven to slide toward both ends of the first shaft 21, respectively. When the rotating member 261 and the rotating member 261 'rotate, the sliding member 262 and the sliding member 262' are driven to slide toward both ends of the second shaft 24, respectively. Until the intermediate door panel 133 is lowered to its lowest position (the position shown in fig. 7B and 10B), the foldable electronic device 10 is in a folded state.
In the following, the first rotating member and the first sliding member in the first driving section will be described as an example of how the first rotating member drives the first sliding member to slide. The second rotating member and the second sliding member in the second driving portion may be implemented in the same manner with reference to the drawings.
In some embodiments, the rotating member 231 and the sliding member 232 are connected by a screw driving structure, and the rotating member 231 drives the sliding member 232 to slide by the screw driving structure. It will be appreciated that the screw drive structure may convert a rotational movement in space about an axis of rotation into a translational movement parallel to the axis of rotation. Thus, the rotary member 231 and the slider 232 of the driving part 23 of the present application are connected by a screw driving structure, so that the rotary motion of the rotary member 231 can be converted into the translational motion of the slider 232 along the first shaft 21. In other embodiments, the rotating member 231 may also slide by driving the sliding member 232 through other mechanisms, such as a cam mechanism, a nut screw mechanism, etc., which is not limited by the present application.
Referring to fig. 11 and 12, fig. 11 is a detail view of a portion a of fig. 7A. Fig. 12 is a detail view of section B of fig. 10A. In some embodiments, the helical drive structure comprises a first helical structure and a second helical structure; the rotating member 231 includes a first sleeve 2311 and a second sleeve 2312 sleeved on the first shaft 21, the first sleeve 2311 and the second sleeve 2312 being spaced apart in the Y direction; the slider 232 includes a third sleeve 2321 sleeved on the first shaft 21, the third sleeve 2321 being disposed between the first sleeve 2311 and the second sleeve 2312; the surface of the first sleeve 2311 facing the third sleeve 2321 is a first spiral surface a, the surface of the third sleeve 2321 facing the first sleeve 2311 is a second spiral surface b, and the first spiral surface a and the second spiral surface b are matched with each other to form a first spiral structure together; the surface of the second sleeve 2312 facing the third sleeve 2321 is a third spiral surface c, the surface of the third sleeve 2321 facing the second sleeve 2312 is a fourth spiral surface d, and the third spiral surface c and the fourth spiral surface d are matched with each other to form a second spiral structure together.
In addition, the rotation member 231 further includes a first swing arm 2313 provided on an outer wall of the first sleeve 2311, and a second swing arm 2314 provided on an outer wall of the second sleeve 2312. In some embodiments, the first swing arm 2313 and the second swing arm 2314 are both connected (directly or indirectly) to the first housing 11, such that the first housing 11 may rotate the first sleeve 2311 through the first swing arm 2312 and rotate the second sleeve 2312 through the second swing arm 2314.
Referring to fig. 11, in the folding process of the foldable electronic device 10, the first housing 11 drives the first swing arm 2313 and the second swing arm 2314 to rotate clockwise around the first shaft 21, and at this time, the first spiral surface a clings to the second spiral surface b and applies a downward force to the second spiral surface b to push the third sleeve 2321 to slide in a direction approaching the second sleeve 2312 (i.e. the illustration Y1), so as to realize conversion from a rotational motion to a translational motion. At this time, the connection end of the first link 22 and the third sleeve 2321 moves in the Y1 direction under the driving of the third sleeve 2321, so that the middle door panel 133 may be driven to descend.
Similarly, referring to fig. 12, during the unfolding process of the foldable electronic device 10, the first housing 11 drives the swing arm 2313 and the second swing arm 2314 to rotate counterclockwise around the first shaft 21, and at this time, the third spiral surface c is closely attached to the fourth spiral surface d, and applies an upward force to the fourth spiral surface d, so as to push the third sleeve 2321 to slide in a direction approaching the first sleeve 2311 (in the Y2 direction shown in the drawing). At this time, under the driving of the third sleeve 2321, the connection end of the first connection rod 22 and the third sleeve 2321 moves toward the Y2 direction, so that the middle door panel 133 may be driven to rise.
It will be appreciated that the helical direction of the helical drive structure may be configured to match the direction of extension of the first link such that the intermediate door panel 133 descends during folding of the electronic device 10 and ascends during unfolding of the electronic device 10. For example, in the example shown in fig. 11, the spiral direction of the rotation driving structure is the right-hand direction, and the extending direction of the first link 22 is from the lower left to the upper right (for example, the arrangement of fig. 5A); in other examples, when the screw direction of the rotation driving structure is the left-handed direction, the extending direction of the first link 22 may be set from the lower right to the upper left (for example, fig. 5C).
In some embodiments, as shown in fig. 11, the sliding member 232 further includes a first sliding block 2322, and correspondingly, the second sliding member in the second driving portion corresponding to the first sliding block 2322 also includes a second sliding block, where the first sliding block 2322 is connected with the second sliding block, so as to ensure sliding synchronization between the first sliding member in the first driving portion and the second sliding member in the second driving portion corresponding to the first sliding member, further improve synchronism of the corresponding first connecting rod and the second connecting rod, and improve lifting stability of the middle door panel 133.
The manner in which each of the first links of the first link mechanism is connected will be described below with reference to the first set of first links 22, and each of the second links of the second link mechanism may be implemented in the same or similar manner. As shown in fig. 13, in some embodiments, one end of the first set of first links 22 is rotatable about a first axis x1 relative to the intermediate door panel 133 and the other end of the first links 22 is rotatable about a second axis x2 relative to the slider 232; wherein the first axis X1 and the second axis X2 are both parallel to the X-direction.
Continuing with the first set of first links 22 as an example, the relative parameter settings for each set of first links in the first linkage may be implemented in the second linkage with reference to the same or similar manner.
Further, considering that if the length of the link is too much, the elevation height of the door plate 133 is too small, the screen capacity of the hinge mechanism is insufficient when the electronic apparatus 10 is in the folded state. However, if the length of the link is too long, the door panel lifting height is too large, the door panel 133 easily comes to the top of the screen, and the drop reliability of the electronic device 10 is affected. Thus, in some embodiments, as shown in connection with fig. 5A, the length L1 of the first set of first links 22 is 2mm to 5mm to compromise screen capacity and drop reliability.
In addition, it is considered that if the distance between two adjacent first sliders is too small, the installation space of the axial part (for example, the first driver) is affected; if the distance between two adjacent first slides is too large, there is a tendency for deviation between the axial displacements between the two first slides. To this end, in some embodiments, the first distance L2 between two adjacent first sliders is 20mm to 50mm in the Y direction to compromise the mounting space of the axial part and the displacement synchronicity between the different first sliders. In addition, the distance between two sets of first links corresponding to two adjacent first sliding members, such as the first link 22 and the two ends of the first link 22', is a second distance L3, wherein L2 is greater than L3, and the difference between L2 and L3 ranges from 4mm to 10mm, i.e., L2-L3 < 4mm-10mm. It should be noted that the above specific parameter settings are all exemplary, and may be specifically determined in combination with the actually required lifting height.
In some embodiments, the intermediate door panel 133 is a segmented structure, i.e., the intermediate door panel 133 is composed of a plurality of sub-door panels. Illustratively, as shown in FIG. 14, the intermediate door panel 133 includes a first sub-door panel 1331 and a second sub-door panel 1332; the first linkage includes four sets of first links, two of which (first set of first links 22 and second set of first links 22 ') are rotatably connected to the first sub-door panel 1331 and two of which (third set of first links 22″ and fourth set of first links 22' ") are rotatably connected to the second sub-door panel 1332. Correspondingly, four first sliding elements, that is, sliding elements 232 corresponding to and connected with the first group of first connecting rods 22, sliding elements 232' corresponding to and connected with the second group of first connecting rods 22', sliding elements 232″ corresponding to and connected with the third group of first connecting rods 22″ and sliding elements 232″ corresponding to and connected with the fourth group of first connecting rods 22', are also arranged on the first shaft 21 corresponding to the four groups of first connecting rods. In this way, the corresponding first link and first slider are provided for each sub-door panel, and the stability of lifting can be ensured regardless of the length of the middle door panel 133.
In summary, in the door panel lifting assembly 20 provided by the embodiment of the application, the parts of the first connecting rod mechanism and the first driving mechanism are fewer, the axial space occupied by the rotating shaft mechanism 13 is small, the first connecting rod mechanism, the first driving mechanism, the second connecting rod mechanism and the second driving mechanism are mainly arranged in the axial space between the first shaft and the second shaft, too many parts are not required to be arranged along the axial direction, and a lot of space can be saved for other functional assemblies of the rotating shaft mechanism in the axial direction.
