As shown in fig. 1 to 11, a folding mechanism 10 according to some embodiments of the present application is used to support a flexible display panel 20 (simply referred to as "display panel 20").
The folding mechanism 10 includes:

when the folding mechanism 10 is in the second folded state, the first surface 113 of the first carrier 11 is opposite to the first surface 123 of the second carrier 12, and the folding assembly 13 and the two carriers (including the first carrier 11 and the second carrier 12, which are the same below) form an accommodating space for accommodating the bending region of the display panel 20.

Correspondingly, the second carrier 12 includes a second screen support plate 121 and a second housing 122, where the second screen support plate 121 is connected to the second housing 122, and the second housing 122 has a cavity therein, and may be used for setting other components of the electronic device.
The folding assembly 13 includes a plurality of interconnected cranks, wherein the cranks at the end and end can be used to connect the first carrier 11 and the second carrier 12, and the crank in the middle can be used to provide a degree of folding freedom to effect the switching of the folding mechanism 10 between the unfolded state and the various folded states (including the first folded state and the second folded state). The number of cranks may be, for example, 4, 5 or more, and the folding assembly 13 may also be referred to as a crank mechanism.
In the embodiment of the present application, the first carrier 11 and the second carrier 12 are connected by the folding assembly 13, and the folding assembly 13 includes a plurality of mutually hinged cranks, and the folding assembly 13 can be switched between various states due to the large folding degree of freedom between the cranks, so that the folding mechanism of the embodiment of the present application can be applied to both the display panel in the inner folding mode and the display panel in the outer folding mode.
In some embodiments, the folding assembly 13 comprises a first crank 131, a second crank 132, a third crank 133 and a fourth crank 134 hinged in sequence, the first crank 131 being connected to the second face 114 of the first carrier 11, the fourth crank 134 being connected to the second face 124 of the second carrier 12;
when the folding mechanism 10 is in the unfolded state, the second crank 132 and the third crank 133 are stretched between the first carrier 11 and the second carrier 12, or folded between the first carrier 11 and the second carrier 12;
when the folding mechanism 10 is in the first folded state, all the cranks of the folding assembly 13 are folded between the first carrier 11 and the second carrier 12;
when the folding mechanism 10 is in the second folded state, the second crank 132 and the third crank 133 bend in a direction away from the two carriers, and form an accommodating space with the two carriers for accommodating the bending region of the display panel 20.
This embodiment provides a four-crank folding assembly 13, herein the folding assembly 13 may also be referred to as a four-crank mechanism, wherein the first crank 131 and the fourth crank 134 are primarily used to connect the first carrier 11 and the second carrier 12 and provide rotational support for the second crank 132 and the third crank 133, and the second crank 132 and the third crank 133 are primarily used to provide a degree of folding freedom to effect switching of the folding mechanism 10 between an unfolded state and a plurality of folded states, including a first folded state and a second folded state.
In this embodiment, the shape of each crank of the folding assembly 13 is not limited, each crank may have a certain free arc, the thickness and length of each crank may be different, for example, the length of the first crank 131 and the fourth crank 134 may be greater than the length of the second crank 132 and the third crank 133, the width of the second crank 132 may be greater than the width of the third crank 133, and so on.
It should be noted that, in addition to the above four cranks hinged in sequence, the folding assembly 13 may further include a plurality of cranks hinged in sequence, and in order to simplify the structure of the folding assembly 13, the embodiment of the present application is described by taking the folding assembly 13 including the above four cranks hinged in sequence as an example.
As shown in fig. 3, when the folding mechanism 10 is in the first folded state, the display panel 20 is folded and exposed to the outside, and thus, the first folded state may correspond to the outside folding mode.
As shown in fig. 4, when the folding mechanism 10 is in the second folded state, the display panel 20 is folded between the first carrier 11 and the second carrier 12, and thus, the first folded state may correspond to the inner folded mode.
When the folding mechanism 10 is in the unfolded state, there is a space between the first carrier 11 and the second carrier 12, and the total length of the second crank 132 and the third crank 133 may be substantially equal to or greater than the space between the two carriers.
Generally, as shown in fig. 3, for the outer folding mode, the bending area of the display panel 20 needs to be reserved for the thickness of the first carrier 11 and the second carrier 12, and for the thickness of the folding component 13 added when folding between the first carrier 11 and the second carrier 12, so the interval between the first carrier 11 and the second carrier 12 is generally larger. In this case, the second crank 132 and the third crank 133 may extend between the first carrier 11 and the second carrier 12 when the folding mechanism 10 is in the unfolded state.
In general, as shown in fig. 4, for the inner folding mode, the bending area of the display panel 20 does not need to reserve the thicknesses of the first carrier 11 and the second carrier 12, and thus, the interval between the first carrier 11 and the second carrier 12 is generally smaller. In this case, when the folding mechanism 10 is in the unfolded state, the second crank 132 and the third crank 133 can be folded between the first carrier 11 and the second carrier 12.
The folding mechanism 10 provided in the embodiments of the present application can be compatible with an outer folding mode and an inner folding mode. In this case, when the folding mechanism 10 is in the unfolded state, the second crank 132 and the third crank 133 may extend between the first carrier 11 and the second carrier 12, or may be folded between the first carrier 11 and the second carrier 12.
According to the folding mechanism 10 of the embodiment of the application, the first carrier 11 and the second carrier 12 are connected through the folding assembly 13, the folding assembly 13 comprises the first crank 131, the second crank 132, the third crank 133 and the fourth crank 134 which are hinged in sequence, and the folding assembly 13 can be switched between various states due to the fact that the folding degree of freedom between the cranks is large, and the design form of the folding assembly 13 is more changeable. Therefore, the folding mechanism 10 of the embodiment of the present application can be applied to both the display panel 20 in the inner folding mode and the display panel 20 in the outer folding mode, and compared with the existing folding structure, the application range is wider, which is beneficial to the realization of different folding modes of the electronic device. In addition, the folding mechanism 10 provided in the embodiment of the present application has a simple structure of the folding assembly 13 and a connection form between different components, and is easy to implement.
As described above, the folding mechanism 10 provided in the embodiment of the present application may be compatible with the external folding mode and the internal folding mode, in which case, it is necessary to provide the second crank 132 and the third crank 133 with a sufficient degree of folding freedom, specifically, including the degree of folding freedom of the second crank 132 with respect to the first crank 131, the degree of folding freedom of the second crank 132 with respect to the third crank 133, the degree of folding freedom of the third crank 133 with respect to the second crank 132, and the degree of folding freedom of the third crank 133 with respect to the fourth crank 134.
For an application scenario compatible with the outer folding mode and the inner folding mode, in order to ensure that the second crank 132 and the third crank 133 have a sufficient folding degree of freedom, each adjacent crank of the folding assembly 13 may be hinged by a hinge or a rotation shaft with a larger degree of freedom of rotation.
Further, for applications compatible with the outer fold mode and the inner fold mode, the angle between any adjacent cranks of the folding assembly 13 is maintained by damping.
Damping includes, but is not limited to, friction damping, viscous damping, elastic damping, etc., as examples, friction dampers, viscous dampers, damped hinges, etc. may be provided at the connection between adjacent cranks.
In this embodiment, the angle between the adjacent cranks is maintained by damping, so that the display panel 20 can be stably maintained at a plurality of different angles, and the use effect of the display panel 20 is improved.
As described above, the folding mechanism 10 provided in the embodiment of the present application may also be applied to an application scenario that provides only the outer folding mode, or an application scenario that provides only the inner folding mode.
For an application scenario where only a single folding mode is provided, the present embodiment may limit the folding degrees of freedom of the second crank 132 and the third crank 133 to a suitable range by the following embodiments.
As shown in fig. 5, a first side wall of the first crank 131 is provided with a first sliding groove 1311, a second side wall of the second crank 132 is provided with a second sliding groove 1321, and a first side wall of the fourth crank 134 is provided with a third sliding groove 1341;
the folding assembly 13 further includes:
the first link 135, one end of the first link 135 is hinged with the second crank 132, and the other end is slidably connected with the first chute 1311;
the second connecting rod 136, one end of the second connecting rod 136 is hinged with the third crank 133, and the other end is connected with the second sliding groove 1321 in a sliding way; and
and a third link 137, one end of the third link 137 is hinged to the third crank 133, and the other end is slidably connected to the third chute 1341.
Specifically, the first link 135 is hinged to the first side wall of the second crank 132, the second link 136 is hinged to the second side wall of the third crank 133, and the third link 137 is hinged to the first side wall of the third crank 133, wherein the first side walls of the first crank 131, the second crank 132, the third crank 133 and the fourth crank 134 are all the same in orientation, and the second side walls of the first crank 131, the second crank 132, the third crank 133 and the fourth crank 134 are all the same in orientation.
The cranks provided with the sliding grooves may be interchanged, for example, the sliding grooves may be provided in the first crank 131, the third crank 133, and the fourth crank 134. In order to ensure structural stability, it is optional to provide a runner on the crank of greater width.
In this embodiment, the rotation angle of the folder assembly 13 may be limited by the first, second and third links 135, 136 and 137 during the rotation of the folder assembly 13.
As shown in fig. 6, taking the folding degree of freedom between the second crank 132 and the third crank 133 as an example, when the folding assembly 13 is folded, the second link 136 slides to the leftmost end along the second sliding groove 1321, and is limited by the left end of the second sliding groove 1321, so that the folding angle between the second crank 132 and the third crank 133 does not exceed the designed folding angle. Accordingly, when the folding assembly 13 is unfolded, the second link 136 slides to the rightmost end along the second sliding groove 1321, and is limited by the right end of the second sliding groove 1321, so that the unfolding angle between the second crank 132 and the third crank 133 does not exceed the designed unfolding angle.
Here, the second link 136 can limit the folding degree of freedom between the second crank 132 and the third crank 133, and can form a triangle-shaped stable structure together with the second crank 132 and the third crank 133, thereby improving the overall stability of the folding assembly 13.
Further, as shown in fig. 6, the first, second and third links 135, 136 and 137 may have a slider 138 at one end slidably connected to the sliding slot, and the slider 138 is embedded in the sliding slot and may slide along the sliding slot. Specifically, the first link 135 is slidably connected to the first chute 1311 through the first slider 138, the second link 136 is slidably connected to the second chute 1321 through the second slider 138, and the third link 137 is slidably connected to the third chute 1341 through the third slider 138.
The above structure may be referred to as a four crank link mechanism, and may also be referred to as a crank block 138 angle control structure.
The bending length of the bending area of the display panel 20 generally changes during the folding and unfolding processes, and the space requirement of the bending area of the display panel 20 is different in different folding modes, so that the length of the display panel 20 cannot be extended or contracted.
In the embodiment of the present application, in order to realize the display panel 20 switching between the various folded modes, the folding assembly 13 can be in any one of the following four modes: firstly, when the folding assembly 13 is folded in the outer folding mode, the top screen is prevented from being folded in the folding assembly; secondly, when the folding assembly 13 is unfolded in the external folding mode, the folding assembly is unfolded to bear the unfolded display panel 20; thirdly, when folding in the inner folding mode, the folding assembly 13 is unfolded to accommodate the folding area when the display panel 20 is folded inwards; fourth, when the screen is unfolded in the inner folding mode, the folding assembly 13 is folded to prevent the screen from being pulled when the screen is unfolded.
When the display panel 20 is folded, the folding assembly 13 can be folded between the two supporting bodies by utilizing the folding and folding principle of the multi-crank structure, so that the situation that the multi-crank structure protrudes out of the two supporting bodies to prop up the display panel 20 can be avoided, and the display panel 20 can be ensured to be folded outwards smoothly.
Specifically, as shown in fig. 2, when the folding mechanism 10 is unfolded, the folding assembly 13 is in a linear unfolded state, and when the folding mechanism 10 is folded out, the folding assembly 13 is folded inward in an "M" shape, preventing the folding assembly 13 from being pushed up to the display panel 20.
When the inner folding is performed, the folding assembly 13 can be folded in a direction away from the two carriers by utilizing the principle of unfolding and stretching of the multi-crank structure, so that the folding assembly 13 can be unfolded and stretched relative to the two carriers, and the accommodating space formed by the unfolded and stretched part can be used for accommodating the folded and bent display panel 20, thereby ensuring that the display panel 20 is folded inwards smoothly.
Specifically, as shown in fig. 2, when the folding mechanism 10 is unfolded, the folding assembly 13 is in a V-shaped unfolded state, and when the folding mechanism 10 is folded, the folding assembly 13 is folded outwards in a U-shape, and after folding, the folded region of the display panel 20 can be accommodated in the U-shaped accommodating space.
In some embodiments, in order to stably maintain the display panel 20 at a plurality of different angles, the angle between any adjacent cranks of the folder assembly 13 may be maintained by damping, or the angle between the connecting rod and the crank may be maintained by damping between the connecting rod and the crank, thereby maintaining the angle between the cranks.
In still other embodiments, as shown in fig. 7, the first crank 131, the second crank 132 and the fourth crank 134 are further provided with first magnetic members 141 spaced apart along the length direction of the chute;
the ends of the first, second and third links 135, 136 and 137 connected to the slide grooves are further provided with second magnetic members 142.
The polarity of the first magnetic member 141 may be different from that of the second magnetic member 142, so that when the end of the link moves to the position where the first magnetic member 141 is located along the chute, the end of the link can be maintained at the position by the attraction between the first magnetic member 141 and the second magnetic member 142, thereby controlling the folding angle of the folding assembly 13. In addition, the polarity of the first magnetic member 141 may be the same as that of the second magnetic member 142, so that when the end of the link moves to a position between the two first magnetic members 141 along the slide groove, the end of the link can be maintained at the position by repulsive force between the first magnetic member 141 and the second magnetic member 142. The polarity of the first magnetic members 141 may be alternately changed.
The material of the first magnetic member 141 and the second magnetic member 142 may be a magnet, or the material of the first magnetic member 141 may be a magnet, and the material of the second magnetic member 142 may be iron.
The above structure may be referred to as a magnetic hover structure.
Further, in an embodiment in which the slider 138 is provided at one end of the first, second and third links 135, 136 and 137 slidably connected to the slide groove, the second magnetic member 142 may be provided to the slider 138, or the slider 138 may be formed of the second magnetic member 142.
Optionally, the first magnetic member 141 is disposed on the second sidewall of the first crank 131, the first sidewall of the second crank 132, and the second sidewall of the fourth crank 134.
In this way, the first magnetic member 141 faces the second magnetic member 142, and the holding force between the first magnetic member 141 and the second magnetic member 142 can be improved.
Alternatively, as shown in fig. 1, the number of folding assemblies 13 is two, including a first folding assembly 13a and a second folding assembly 13b;
the folding mechanism 10 further includes:
the first transmission shaft 151, the second crank 132 of the first folding assembly 13a is hinged with the third crank 133 through one end of the first transmission shaft 151, and the second crank 132 of the second folding assembly 13b is hinged with the third crank 133 through the other end of the first transmission shaft 151.
Specifically, the first folding component 13a and the second folding component 13b may be respectively connected to two sides of the two carriers, and the first transmission shaft 151 may pass through the rotation centers of the second crank 132 and the third crank 133 of the two folding components 13.
In this embodiment, by the above arrangement, the two folding assemblies 13 can be made to maintain the folding angle of the folding mechanism 10 in synchronization, which can improve the stability of the folding mechanism 10 during folding or unfolding.
In addition, more folding assemblies 13 may be provided to further enhance the stability of the folding mechanism 10 during folding or unfolding, such as providing a first folding assembly, a second folding assembly, and a third folding assembly.
Further, as shown in fig. 1, the folding mechanism 10 further includes:
the second transmission shaft 152, the first crank 131 of the first folding assembly 13a is hinged with the second crank 132 through one end of the second transmission shaft 152, and the first crank 131 of the second folding assembly 13b is hinged with the second crank 132 through the other end of the second transmission shaft 152;
the third crank 133 of the first folding assembly 13a is hinged to the fourth crank 134 through one end of the third transmission shaft 153, and the third crank 133 of the second folding assembly 13b is hinged to the fourth crank 134 through the other end of the third transmission shaft 153.
Specifically, three transmission shafts pass through three rotation centers of the two folding assemblies 13, respectively.
In this embodiment, by the above arrangement, the two folding assemblies 13 can be further synchronized to maintain the folding angle of the folding mechanism 10, which can further improve the stability of the folding mechanism 10 during folding or unfolding.
As described above, for the outer folding mode, the thickness of the first carrier 11 and the second carrier 12 needs to be reserved in the bending area of the display panel 20, and the thickness of the folded module 13 added by folding between the first carrier 11 and the second carrier 12 needs to be reserved, so the space between the first carrier 11 and the second carrier 12 is generally larger. In this case, when the folding mechanism 10 is in the unfolded state, the display panel 20 (i.e., the bending region of the display panel 20) between the first carrier 11 and the second carrier 12 is not supported, which may cause the bending region of the display panel 20 to be concave and uneven. When the folding mechanism 10 is in the first folded state, since the folding module 13 is folded between the first carrier 11 and the second carrier 12, there is also a space between the first carrier 11 and the second carrier 12, and the display panel 20 between the first carrier 11 and the second carrier 12 loses support, which may cause the bending area of the display panel 20 to be concave and uneven.
In view of this, the present embodiment can support the bending region of the display panel 20 by the following embodiments.
As shown in fig. 8 to 9, the folding mechanism 10 further includes a first support 16, the first support 16 including:
a first support plate 161, the first support plate 161 being rotatably connected to the first carrier 11;
the second support plate 162, the second support plate 162 is rotatably connected with the second carrier 12, and the second support plate 162 is rotatably connected with the first support plate 161;
a third support plate 163, the third support plate 163 being connected to the first transmission shaft 151, the third support plate 163 being connected to the first support plate 161 and the second support plate 162 at the connection of the first support plate 161 and the second support plate 162;
when the folding mechanism 10 is in the unfolded state or the first folded state, the first support plate 161 and the second support plate 162 are in the same plane, so as to support the bending area of the display panel 20.
Specifically, as shown in fig. 8, when the folding mechanism 10 is in the unfolded state, the first support plate 161, the second support plate 162, the first surface 113 of the first carrier 11 and the first surface 123 of the second carrier 12 are all located on the same plane, and the first support plate 161, the second support plate 162, the first carrier 11 and the second carrier 12 can jointly support the display panel 20. As shown in fig. 9, when the folding mechanism 10 is in the first folded state, the first support plate 161 and the second support plate 162 are in the same plane and are attached to the end surface of the first carrier 11 and the end surface of the second carrier 12, and the first support plate 161 and the second support plate 162 can jointly support the bending area of the display panel 20. When the folding mechanism 10 is in the unfolded state or the first folded state, the first support 16 is in a "T" shape.
The first support plate 161 may be hinged to the first carrier 11, the second support plate 162 may be hinged to the second carrier 12, the first support plate 161, the second support plate 162, and the third support plate 163 may be hinged to each other, and the third support plate 163 may be hinged to or fixedly connected with the first transmission shaft 151.
The movement of the first support 16 will be described below in connection with the folding or unfolding process of the folding mechanism 10.
Assuming that the folding mechanism 10 is in an unfolded state in the initial state, when the cranks of the folding assembly 13 are in an unfolded state, the first support plate 161 and the second support plate 162 are unfolded between the first carrier 11 and the second carrier 12 and are positioned below the display panel 20 to support the bending region of the display panel 20.
When the folding mechanism 10 is folded from the unfolded state to the first folded state, the folding assembly 13 drives the first supporting body 11 and the second supporting body 12 to rotate relatively, the first supporting body 11 and the second supporting body 12 drive the first supporting plate 161 and the second supporting plate 162 to rotate relatively respectively, and when the folding mechanism 10 is in the first folded state, the first supporting plate 161 and the second supporting plate 162 are attached to the end surfaces of the first supporting body 11 and the second supporting body 12 respectively, and the first supporting body 11 and the second supporting body 12 are located on the same plane to support the bending area of the display panel 20.
This embodiment may be adapted for use in an out-folded mode, and the above structure may be referred to as a screen rotation support structure.
As described above, for the inner folding mode, the bending region of the display panel 20 extends to the receiving space formed by the second crank 132, the third crank 133 and the carrier, and the receiving space is an open receiving space, which makes the structural strength thereof weak, and when an external force is applied thereto, the bending region of the display panel 20 is easily damaged by the impact of the external force.
In view of this, the present embodiment can protect the bending region of the display panel 20 by the following embodiments.
As shown in fig. 10 to 11, the electronic apparatus further includes a second support 17, the second support 17 including:
a fourth support plate 171, one side of the fourth support plate 171 being connected to the first transmission shaft 151, and the other side being connected to the second transmission shaft 152;
a fifth support plate 172, one side of the fifth support plate 172 is connected to the first transmission shaft 151, and the other side is connected to the third transmission shaft 153;
when the folding mechanism 10 is in the second folded state, the fourth support plate 171 and the fifth support plate 172 form a receiving space with the carrier.
The movement of the second support 17 will be described below in connection with the folding or unfolding process of the folding mechanism 10.
Specifically, as shown in fig. 10, assuming that the folding mechanism 10 is in an unfolded state in an initial state, the fourth support plate 171 and the fifth support plate 172 are located between the first carrier 11 and the second carrier 12 to support the middle portion of the bending region of the display panel 20.
As shown in fig. 11, when the folding mechanism 10 is folded from the unfolded state to the second folded state, the folding assembly 13 drives the first carrier 11 and the second carrier 12 to rotate relatively, the fourth support plate 171 and the fifth support plate 172 rotate along with the folding assembly 13, and when the folding mechanism 10 is in the second folded state, the fourth support plate 171 and the fifth support plate 172 can form a containing space together with the two carriers to contain a plurality of bending areas of the display panel 20 due to folding.
Through the above arrangement, the fourth support plate 171 and the fifth support plate 172 can form a non-open accommodating space together with the two supporting bodies, which can not only improve the structural strength of the place, but also protect the bending area of the display panel 20, so as to avoid the bending area of the display panel 20 from being damaged due to external impact.
This embodiment may be adapted for use in an in-folded mode, and the above structure may be referred to as a screen rotation support structure.
Optionally, the fourth support plate 171 and the fifth support plate 172 are hinged by the first transmission shaft 151.
