It should be noted that the angles illustrated in the embodiments of the present application are all allowed to have a slight deviation. For example, the unfolding angle α of the electronic device 400 shown in fig. 2 is 120 degrees, which means that α may be 120 degrees, or may be about 120 degrees, such as 110 degrees, 115 degrees, 125 degrees, or 130 degrees. The unfolding angle β of the electronic device 400 shown in fig. 3 is 180 degrees, which means that β may be 180 degrees, or may be about 180 degrees, such as 0 degree, 5 degrees, 185 degrees, 190 degrees, and the like. The angles illustrated hereinafter are to be understood in the same way.
The electronic device 400 according to the embodiment of the present application is an electronic device that can be folded once. In other embodiments, the electronic device 400 may also be an electronic device that may be folded multiple times (more than two times). At this time, the electronic device 400 may include a plurality of portions, and two adjacent portions may be folded relatively close to each other until the electronic device 400 is in a folded state, and two adjacent portions may be unfolded relatively far from each other until the electronic device 400 is in an unfolded state.

Referring to fig. 4 and 5, the electronic device 400 includes a folding device 200 and a flexible display 300, wherein the flexible display 300 is mounted on the folding device 200. The flexible display 300 comprises a first portion 310, a second portion 320 and a foldable portion 330. The foldable portion 330 is located between the first portion 310 and the second portion 320, and the foldable portion 330 may be bent. The first portion 310, the second portion 320 and the foldable portion 330 together form the flexible display 300.
In an embodiment of the present application, the flexible display 300 may be an organic light-emitting diode (OLED) display, an active matrix organic light-emitting diode (AMOLED) display, a mini-OLED (micro-organic light-emitting diode) display, a micro-led (micro-organic light-emitting diode) display, a quantum dot light-emitting diode (QLED) display.
The folding device 200 includes a first housing 210, a second housing 220 and a rotating mechanism 100, wherein the first housing 210 has a first receiving groove 230, the second housing 220 has a second receiving groove 240, and the first receiving groove 230 and the second receiving groove 240 are communicated to form a receiving groove. The rotating mechanism 100 is installed in the accommodating groove and is fixedly connected to the first casing 210 and the second casing 220, so as to realize the rotating connection between the first casing 210 and the second casing 220. The first housing 210 and the second housing 220 can be relatively rotated by the rotating mechanism 100, so that the folding device 200 is switched between the folded state and the unfolded state. The first housing 210 and the second housing 220 are further provided with an accommodating space (not shown) for accommodating electronic components and structural elements of the electronic device 400, such as a processor, a circuit board, a camera module, and the like.
As shown in fig. 1, the relative rotation of the first housing 210 and the second housing 220 enables the folding apparatus 200 to be in a folded state, which means that the first housing 210 and the second housing 220 are rotated by the rotating mechanism 100 and are close to each other, and the surfaces of the first housing 210 and the second housing 220, which bear the flexible display screen 300, are opposite to each other. In practice, in the application process, when the folding device 200 is in the fully folded state, and the flexible display 300 mounted on the first casing 210 and the second casing 220 is folded, the first portion 310 and the second portion 320 are stacked and partially contact, but may be in full contact.
As shown in fig. 2, the relative rotation of the first housing 210 and the second housing 220 to make the folding device 200 in the intermediate state means that the first housing 210 and the second housing 220 rotate through the rotating mechanism 100 and move away from each other to make the included angle between the first housing 210 and the second housing 220 larger and smaller, or that the first housing 210 and the second housing 220 rotate through the rotating mechanism 100 and move close to each other to make the included angle between the first housing 210 and the second housing 220 smaller and smaller.
As shown in fig. 3, the relative rotation of the first housing 210 and the second housing 220 to make the folding device 200 in the unfolded state means that the first housing 210 and the second housing 220 rotate through the rotating mechanism 100 and are far away from each other, and the included angle between the first housing 210 and the second housing 220 continues to increase, and may be close to 180 degrees or equal to 180 degrees.
The flexible display 300 is attached to the folding device 200. Specifically, the first housing 210 carries a first portion 310 of the flexible display 300, the second housing 220 carries a second portion 320 of the flexible display 300, and the foldable portion 330 of the flexible display 300 is disposed opposite to the rotation mechanism 100. It can be understood that the first housing 210 and the second housing 220 are rotated relatively by the rotating mechanism 100, and the flexible display 300 is folded by the relative approach of the first housing 210 and the second housing 220, so that the electronic device 400 is folded. When the electronic device 400 is in a folded state, the foldable portion 330 of the flexible display 300 is bent, and the first portion 310 and the second portion 320 are disposed opposite to each other. At this time, the flexible display screen 300 is located between the first casing 210 and the second casing 220, so that the probability that the flexible display screen 300 is damaged can be greatly reduced, and the flexible display screen 300 is effectively protected.
In the embodiment of the present application, the first housing 210 and the second housing 220 rotate relatively through the rotating mechanism 100, and the flexible display 300 is unfolded by relatively moving the first housing 210 and the second housing 220 away from each other, so that the electronic device 400 is unfolded to the intermediate state. When the electronic device 400 is in the intermediate state, the first housing 210 and the second housing 220 are unfolded to form an included angle α, and the first portion 310 and the second portion 320 are unfolded relatively to each other and drive the foldable portion 330 to unfold. At this time, an angle between the first portion 310 and the second portion 320 is α. In this example, α is 120 degrees. In other embodiments, α may also be about 120 degrees, and may also be 110 degrees, 115 degrees, 125 degrees, 130 degrees, or the like.
The first housing 210 and the second housing 220 rotate relatively through the rotating mechanism 100, and the flexible display screen 300 is further unfolded by the relative distance between the first housing 210 and the second housing 220 until the electronic device 400 is unfolded. When the folding device 200 is in the unfolded state, the angle between the first housing 210 and the second housing 220 is β. The foldable portion 330 is unfolded and the first portion 310 and the second portion 320 are relatively unfolded. At this time, included angles between the first portion 310, the second portion 320 and the foldable portion 330 are all β, and the flexible display screen 300 has a large-area display area, so that large-screen display of the electronic device 400 is realized, and use experience of a user is improved. In this example, β is 180 degrees. In other embodiments, β may also be approximately 180 degrees, may be 0 degrees, 5 degrees, 185 degrees, 190 degrees, and so on.

Specifically, when the electronic device 400 is in the unfolded state, the rotating mechanism 100 is also in the unfolded state, and the main swing arm assembly 40, the support plate assembly 70 and the support swing arm assembly 50 are flush with each other, so that the flexible display screen 300 can be supported together, and thus the flexible display screen 300 is more flat and is not easily damaged by external force touch, and the reliability of the flexible display screen 300 is improved. When the electronic device 400 is in the folded state, the rotating mechanism 100 is also in the folded state, and the first fixing frame 20 and the second fixing frame 30 can be folded to be parallel to each other, so that the main swing arm assembly 40, the support plate assembly 70 and the support swing arm assembly 50 together form the accommodating space 11 for accommodating the flexible display screen 300, thereby providing more excellent support performance for the flexible display screen 300. For example, the housing space 11 may take a form of a water droplet, or the housing space 11 may take a form of a baseball.

The seventh cam structure 6861 includes a plurality of protrusions and a plurality of recesses, and each two adjacent protrusions are connected by one recess, so that the seventh cam structure 6861 can exhibit an uneven undulating shape.
The seventh cam structure 6861 abuts the fifth cam structure 683 and is movable in the axial direction of the first rotary shaft 65 under the urging of the fifth cam structure 683.

The first elastic element 687 is disposed around the first rotating shaft 65, and the first elastic element 687 is elastically pressed between the third cam structure 6851 and the seventh cam structure 6861. Therefore, the first elastic element 687 has a good elastic force, so that the third cam structure 6851 is pushed to enable the third cam structure 6851 to be in contact with the first cam structure 681 in a pressing manner, and the seventh cam structure 6861 is pushed to enable the seventh cam structure 6861 to be in contact with the fifth cam structure 683 in a pressing manner, so that the damping effect which can be realized by the first cam structure 681 and the third cam structure 6851, and the fifth cam structure 683 and the seventh cam structure 6861 is ensured.
It will be appreciated that because the third camming structure 6851 has room for axial movement, the first camming structure 681 is always in good mating contact with the third camming structure 6851. Therefore, under the condition that the first cam structure 681 rotates, the third cam structure 6851 axially moves along the first rotating shaft 65, and compresses or releases the first elastic element 687, so that the damping effect is improved, and the use experience of a user during folding is improved.
During the rotation of the first synchronous swing arm 63, the first cam structure 681 at the first rotation end 631 and the third cam structure 6851 of the first sliding cam 685 move relatively, which is to be understood that the third cam structure 6851 is pressed to slide relative to the first cam structure 681, so that the axial distance between the first and third cam structures is changed, and the first elastic element 687 is compressed to generate a damping force.
Because the seventh cam structure 6861 has an axial movement space, the fifth cam structure 683 and the seventh cam structure 6861 are always in good fit contact. Therefore, under the condition that the fifth cam structure 683 rotates, the seventh cam structure 6861 axially moves along the first rotating shaft 65 to compress or release and compress the first elastic element 687, so that the damping effect is improved, and the use experience of a user during folding is improved.
During the rotation of the first synchronous swing arm 63, the fifth cam structure 683 at the first rotation end 631 thereof and the seventh cam structure 6861 of the second sliding cam 686 generate a relative movement, which can be understood as that the seventh cam structure 6861 slides relative to the fifth cam structure 683 under the compression, so that the axial distance between the fifth cam structure 683 and the seventh cam structure 6861 changes, thereby compressing the first elastic element 687 to generate a damping force.
The second elastic member 688 is disposed on the second rotating shaft 66, and the second elastic member 688 elastically abuts between the fourth cam structure 6852 and the eighth cam structure 6862. Therefore, due to the good elastic force of the second elastic member 688, the fourth cam structure 6852 is pushed to enable the fourth cam structure 6852 to be in pressing contact with the second cam structure 682, and the eighth cam structure 6862 is pushed to enable the eighth cam structure 6862 to be in pressing contact with the sixth cam structure 684, so that the damping effect achieved by the second cam structure 682 and the fourth cam structure 6852, and the sixth cam structure 686 and the eighth cam structure 6862 is ensured.
It will be appreciated that because the fourth camming structure 6852 has room for axial movement, the second camming structure 682 is always in good mating contact with the fourth camming structure 6852. Therefore, when the second cam structure 682 rotates, the fourth cam structure 6852 moves axially along the second rotating shaft 66 to compress or release the compression of the second elastic member 688, so as to improve the damping effect and improve the user experience during folding.
During the rotation of the second synchronization swing arm 64, the second cam structure 682 disposed at the second rotating end 641 generates a relative movement with the fourth cam structure 6852 of the second slide cam 686, and the relative movement can be understood as that the fourth cam structure 6852 is pressed to slide relative to the second cam structure 682, so that the axial distance therebetween is changed, and the second elastic member 688 is compressed to generate a damping force.
And because the eighth cam structure 6862 has space for axial movement, the sixth cam structure 684 and the eighth cam structure 6862 are always in good mating contact. Therefore, under the condition that the sixth cam structure 684 rotates, the eighth cam structure 6862 axially moves along the second rotating shaft 66 to compress or release the compression second elastic member 688, so that the damping effect is improved, and the use experience of a user during folding is improved.
During the rotation of the second synchronous swing arm 64, the sixth cam structure 684 disposed at the second rotation end 641 and the eighth cam structure 6862 of the second sliding cam 686 generate a relative movement, which can be understood as that the eighth cam structure 6862 is pressed to slide relative to the sixth cam structure 684, so that the axial distance between the sixth cam structure 686 and the sixth cam structure 684 is changed, and the second elastic member 688 is compressed to generate a damping force.
Based on the above description, it should be understood that since both ends of the first elastic member 687 are pressed by the first sliding cam 685 and the second sliding cam 686, respectively, the pressing force applied to the first elastic member 687 is doubled compared to the case where only one end is pressed in the related art, and the damping force provided by pressing the first elastic member 687 is doubled. Both ends of the second elastic member 688 are respectively extruded by the first sliding cam 685 and the second sliding cam 686, so that the second elastic member 688 is extruded for only one end in the prior art, the extrusion force received is multiplied, and the damping force that the extrusion second elastic member 688 can provide is doubled, which is favorable for improving the damping force effect of the rotating mechanism 100, and the reliability is good.

The fifth stopper 695 is connected to the first rotating shaft 65, the second rotating shaft 66, the gear shaft of the first synchronizing gear 675, and the gear shaft of the second synchronizing gear 676. The sixth limiting member 696 is connected to the first rotating shaft 65 and the second rotating shaft 66, and abuts against the fifth limiting member 695. The limiting members are used for limiting the movement of the structures sleeved on the first rotating shaft 65 in the axial direction of the first rotating shaft 65 and limiting the movement of the structures sleeved on the second rotating shaft 66 in the axial direction of the second rotating shaft 66, so as to ensure that the synchronous movement of the gear swing arm assembly 60 does not deflect, and the reliability is good.
