Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a folding side-pull device and an electronic device. Background Art

[0002] As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of these is the emergence of foldable mobile phones, computers and other electronic devices. The flexible screens of foldable electronic devices can flexibly change modes according to different usage scenarios. At the same time, they also have a high screen-to-body ratio and clarity. For example, when the phone is folded, it can be only the size of a traditional phone, which is convenient to carry, and when unfolded, it can have the display size of a tablet. These features make foldable devices one of the products that people are most sought after.

[0003] At present, foldable electronic devices generally include a first structural member and a second structural member that are pivotally connected. For example, the first structural member and the second structural member can be connected by a rotating shaft, so that the first structural member and the second structural member can rotate relative to each other, and then the first structural member and the second structural member can be overlapped or unfolded with each other, and the flexible screen covering the first structural member and the second structural member bends and unfolds as the first structural member and the second structural member are folded and unfolded.

[0004] However, in the above-mentioned foldable electronic devices, the area of ​​the flexible screen after expansion through one unfolding operation is at most twice the original area of ​​the flexible screen, and the area of ​​the flexible screen needs to be further increased to improve the user experience. Summary of the Invention

[0005] The present application provides a folding side-pull device and an electronic device, which solves the problem of existing foldable electronic devices that the flexible screen area can be expanded to twice the original size after one unfolding operation, and the flexible screen area needs to be further increased.

[0006] A first aspect of an embodiment of the present application provides a folding side-pull device, comprising a first structural member, a second structural member, a folding mechanism, and a first side-pull member, wherein the first structural member and the second structural member are rotatably connected via the folding mechanism so that the first structural member and the second structural member are relatively folded or unfolded;

[0007] The first side pulling member is slidably connected to an end of the second structural member away from the folding mechanism, and the first structural member, the second structural member, the folding mechanism and the first side pulling member are used to support the flexible screen;

[0008] The first side pull member is used to slide toward the direction close to the second structural member so that part of the flexible screen is wrapped around the first side pull member; the first side pull member is also used to slide toward the direction away from the second structural member so that the flexible screen wrapped around the first side pull member is unfolded on the first side pull member.

[0009] In this way, when the first and second structural members move toward each other, the first side member can slide toward the second structural member, shortening the distance between the first side member and the end of the second structural member distal from the first side member. When the first and second structural members move away from each other, the first side member can slide away from the second structural member, lengthening the distance between the first side member and the end of the second structural member distal from the first side member. The flexible screen can be slidably mounted with the first side member. The flexible screen can be mounted on the first surface (the side proximal to the display surface) of the first side member. When the first side member slides toward the second structural member, the flexible screen can also slide relative to the first side member. A portion of the edge of the flexible screen can bend along the edge of the first side member distal from the second structural member and slide to extend onto the second surface (opposite the first surface) of the first side member, thereby wrapping around the first side member. When the first side member slides away from the second structural member, the flexible screen slides relative to the first side member, causing the flexible screen wrapped around the first side member to unfold on the first surface of the first side member. That is, when the first structural member and the second structural member move away from each other, the first side pull member slides away from the second structural member, so that the distance between the second structural member and the first side pull member is lengthened, and the flexible screen originally wrapped around the first side pull member is unfolded on the first side pull member, thereby expanding the total size area of ​​the flexible screen located on the second structural member and the first side pull member. That is, when the first structural member and the second structural member are folded to unfolded, the size of the flexible screen of the electronic device after unfolding is expanded, so that the area of ​​the flexible screen after one unfolding operation is doubled or more, effectively increasing the area of ​​the display area, improving the user experience and screen display effect.

[0010] In a possible implementation, the device further includes a side pulling mechanism and a linkage mechanism, wherein the side pulling mechanism is connected to the first side pulling member and is used to drive the first side pulling member to slide relative to the second structural member;

[0011] The side-pull mechanism and the folding mechanism are connected via the linkage mechanism, and the linkage mechanism is used to drive the side-pull mechanism to slide the first side-pull member toward the second structure member when the first structure member and the second structure member move toward each other;

[0012] The linkage mechanism is used to drive the side pulling mechanism to slide the first side pulling member in a direction away from the second structural member when the first structural member and the second structural member move away from each other.

[0013] When the first structural member and the second structural member are rotated to fold or unfold, the linkage mechanism can automatically trigger the relative sliding between the first side pull member and the second structural member according to the rotation state of the first structural member and the second structural member, so that part of the flexible screen is wrapped around or unfolded on the first side pull member, thereby expanding the display screen size.

[0014] In a possible implementation, the folding mechanism includes a main shaft and a first rotating member, one end of the first rotating member is rotatably connected to the main shaft, and the other end of the first rotating member is slidably connected to the second structural member;

[0015] One end of the linkage mechanism is connected to the first rotating member, and the other end of the linkage mechanism is connected to the side pulling mechanism.

[0016] In this way, the first rotating member can rotate relative to the main shaft, which can drive the second structural member to rotate relative to the main shaft. During the rotation, one end of the first rotating member can slide toward the end of the second structural member closer to the main shaft or toward the end of the second structural member farther from the main shaft, that is, the first rotating member and the second structural member slide relative to each other, generating a first sliding displacement. The linkage mechanism can use this first sliding displacement to drive the side pulling mechanism, so that the side pulling mechanism drives the first side pulling member to slide, achieving the conversion between angular velocity and linear velocity. Therefore, when the first and second structural members rotate, the first side pulling member is automatically triggered to slide relative to the second structural member.

[0017] In a possible implementation, the side-pull mechanism is a side-pull connecting rod, and the linkage mechanism includes an input connecting rod and a displacement amplifier;

[0018] One end of the input connecting rod is fixedly connected to the first rotating member, and the other end of the input connecting rod is connected to the displacement amplifier, and the displacement amplifier is connected to the side pull connecting rod. The displacement amplifier is used to amplify the first sliding displacement of the input connecting rod relative to the second structural member into a second sliding displacement, and drive the side pull connecting rod to drive the first side pull member to slide with the second sliding displacement.

[0019] Due to the change in the rotation angle between the first structural member and the second structural member, the displacement of the first rotating member is smaller, so that the displacement that drives the first side pulling member to slide is limited. The first sliding displacement generated between the first rotating member and the second structural member is amplified by the displacement amplifier to be a second sliding displacement to drive the side pulling mechanism. The side pulling mechanism drives the first side pulling member to slide, which can ensure that the rotation of the first structural member and the second structural member causes the displacement generated by the first rotating member to drive the first side pulling member to slide relative to the second structural member.

[0020] In a possible implementation, the displacement amplifier includes a driving gear and a driven gear, the driving gear and the driven gear are coaxially arranged, and the radius of the driving gear is smaller than the radius of the driven gear;

[0021] A rack is provided on the side of the input connecting rod opposite to the driving gear, and the driving gear and the rack of the input connecting rod are meshed with each other; a rack is provided on the side of the side pulling connecting rod opposite to the driven gear, and the driven gear and the rack of the side pulling connecting rod are meshed with each other.

[0022] The first sliding displacement between the first rotating member and the second structural member drives the driving gear with a smaller radius to rotate through the input connecting rod, and the driving gear drives the driven gear with a larger radius to rotate, thereby amplifying the first sliding displacement into a second sliding displacement, thereby achieving amplification of the first sliding displacement.

[0023] In one possible implementation, the displacement amplifier includes at least two gear assemblies, each of the gear assemblies includes a driving gear and a driven gear, the driving gear and the driven gear in each gear assembly are coaxially arranged, the radius of the driving gear in each gear assembly is smaller than the radius of the driven gear, and the driving gear of one of the at least two gear assemblies is meshed with the driven gear of the other gear assembly;

[0024] The input connecting rod and the side pull connecting rod are provided with racks on the side opposite to the gear assembly, wherein the driving gear of one gear assembly is engaged with the rack of the input connecting rod, and the driven gear of the other gear assembly is engaged with the rack of the side pull connecting rod.

[0025] In this way, multiple gear assemblies can increase the amplification factor of the first sliding displacement, better ensure that the rotation of the first structural member and the second structural member enables the displacement generated by the first rotating member to drive the first side pulling member to slide relative to the second structural member, and at the same time, it can also enable the first side pulling member to slide a farther distance relative to the second structural member, which is conducive to meeting the demand for a larger size of the flexible screen after unfolding.

[0026] In a possible implementation, a rotation angle is defined between the first structural member and the second structural member, and the linkage mechanism is a control module configured to drive the side-pull mechanism to slide the first side-pull member according to a change in the rotation angle.

[0027] When the first structural member and the second structural member rotate, the rotation angle between the first structural member and the second structural member changes. The control module can convert the angle value into a corresponding sliding distance and send the sliding distance value to the side pulling mechanism. After the side pulling mechanism obtains the sliding distance value of the control module, it controls the first side pulling member to slide a corresponding distance relative to the second structural member, thereby automatically triggering the sliding of the first side pulling member relative to the second structural member while the first structural member and the second structural member rotate.

[0028] In one possible implementation, the side-pull mechanism includes a shaft, a driver, and a pushing member, the shaft and the driver are fixed on the second structural member, one end of the pushing member is fixed to the first side-pull member, and the other end of the pushing member is wrapped around the shaft, the driver is connected to the shaft to drive the shaft to rotate, and the control module is connected to the driver.

[0029] When the control module generates a corresponding sliding distance based on the rotation angle value, the sliding distance information is sent to the driver. The driver drives the shaft to rotate according to the sliding distance. The pushing member on the shaft will also extend or contract as the shaft rotates, and then the pushing member pushes the first side pull member to slide toward or away from the second structural member, thereby realizing sliding drive of the first side pull member.

[0030] In one possible implementation, the side-pulling mechanism includes a fixed part, a telescopic part and a movable part, the fixed part is arranged on the second structural part, the fixed part and the movable part are connected through the telescopic part, the movable part is connected to the first side-pulling part, and the control module is connected to the telescopic part to drive the telescopic part to retract.

[0031] The control module can send the corresponding sliding distance to the telescopic member, drive the telescopic member to drive the movable member to move the corresponding distance, and then drive the first side pull member to slide the corresponding distance toward or away from the second structural member through the movable member, thereby realizing sliding drive of the first side pull member.

[0032] In a possible implementation, it further includes a screen pulling mechanism, wherein the screen pulling mechanism is disposed in the first side pulling member;

[0033] The screen traction mechanism is used to drive the flexible screen to slide relative to the first side pulling member so as to be wrapped around the first side pulling member when the first side pulling member slides toward the second structural member;

[0034] The screen traction mechanism is used to drive the flexible screen to slide relative to the first side pulling member so as to be unfolded on the first side pulling member when the first side pulling member slides in a direction away from the second structural member.

[0035] The screen traction mechanism can pull the sliding of the flexible screen, facilitating the sliding of the flexible screen, and ensure that the sliding of the first side puller is synchronized with the sliding of the flexible screen, avoiding asynchronous sliding causing improper force on the flexible screen and damaging the flexible screen.

[0036] In one possible implementation, the screen traction mechanism includes a first transmission belt, a first gear and a second gear disposed opposite to each other, and a second transmission belt wound around the first gear and the second gear. The first gear and the second gear are rotatably disposed within the first side pulling member, and the first transmission belt is fixed to the second structural member. The first transmission belt is a rigid and bendable structural member.

[0037] One of the two opposite surfaces of the first transmission belt and the second transmission belt has a groove, and the other surface has a protrusion that cooperates with the groove. The first transmission belt and the second transmission belt are engaged and connected by the groove and the protrusion. The side of the first transmission belt opposite to the second transmission belt is used to fit the flexible screen.

[0038] When the first side member slides relative to the second structural member, the first transmission belt drives the first gear and the second gear to rotate via the second transmission belt, causing the first transmission belt and the first side member to slide relative to each other, thereby pulling the flexible screen to slide synchronously, improving the sliding properties of the flexible screen and facilitating the winding or unfolding of the flexible screen on the first side member as the first side member slides. Simultaneously, the flexible screen fits against the first transmission belt, and the first transmission belt engages with the second transmission belt. The screen traction mechanism limits the position of the flexible screen during winding and unfolding, reducing the occurrence of problems such as bulging or curling of the flexible screen during winding or unfolding.

[0039] In a possible implementation, the device further includes a second side puller, the second side puller being slidably connected to the first structural member, and the second side puller being used to support the flexible screen;

[0040] The second side pulling member is used to slide toward the direction close to the first structural member so that part of the flexible screen is wrapped around the second side pulling member; the second side pulling member is used to slide toward the direction away from the first structural member so that the wrapped flexible screen is unfolded on the second side pulling member.

[0041] Specifically, when the second side member slides toward the first structural member, the flexible screen also slides relative to the second side member. A portion of the edge of the flexible screen can bend along the edge of the second side member away from the first structural member and slide to extend onto the second surface of the second side member (the side opposite the first surface), thereby wrapping around the second side member. When the second side member slides away from the first structural member, the flexible screen slides relative to the second side member, causing the flexible screen wrapped around the second side member to unfold onto the first surface of the second side member. In this way, the sliding of the second side member away from the first structural member lengthens the distance between the first structural member and the second side member, causing the flexible screen originally wrapped around the second side member to unfold onto the second side member. This expands the total area of ​​the flexible screen located on the first structural member and the second side member, further increasing the size of the unfolded flexible screen. This increases the area of ​​the flexible screen after a single unfolding operation, further increasing the display area and meeting user needs for large-size displays.

[0042] A second aspect of the embodiments of the present application provides an electronic device, comprising a flexible screen and any one of the above-described folding side-pull devices, wherein the flexible screen is disposed on a first surface of the folding side-pull device, and the flexible screen and the first side-pull member are slidably disposed;

[0043] When the first side pulling member slides toward the second structural member, the edge of the flexible screen bends along the edge of the first side pulling member away from the second structural member and slides to extend to the second surface of the first side pulling member opposite to the first surface;

[0044] When the first side pulling member slides in a direction away from the second structural member, the flexible screen unfolds on the first surface of the first side pulling member.

[0045] In this way, when the first structural member and the second structural member move toward each other, the first side pull can slide toward the direction closer to the second structural member, shortening the distance between the first side pull and the end of the second structural member away from the first side pull. When the first structural member and the second structural member move away from each other, the first side pull can also slide toward the direction away from the second structural member, lengthening the distance between the first side pull and the end of the second structural member away from the first side pull. When the first side pull slides toward the direction closer to the second structural member, the edge of part of the flexible screen can bend along the edge of the first side pull away from the end of the second structural member and slide to the second surface of the first side pull (the side opposite to the first surface), thereby being wound around the first side pull. When the first side pull slides toward the direction away from the second structural member, the flexible screen slides relative to the first side pull, causing the flexible screen wound around the first side pull to unfold on the first surface of the first side pull. That is, when the first structural member and the second structural member move away from each other, the first side pull member slides away from the second structural member, so that the distance between the second structural member and the first side pull member is lengthened, and the flexible screen originally wrapped around the first side pull member is unfolded on the first side pull member, thereby expanding the total size area of ​​the flexible screen located on the second structural member and the first side pull member. That is, when the first structural member and the second structural member are folded to unfolded, the size of the unfolded flexible screen is expanded, so that the area of ​​the flexible screen after one unfolding operation is doubled or more, effectively increasing the area of ​​the display area of ​​the electronic device, improving the user experience and screen display effect.

DETAILED DESCRIPTION

[0076] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0077] Foldable electronic devices, such as mobile phones, can typically be folded into two or three layers. When folded, the phone can be the size of a traditional phone, while when unfolded, it can have the display size of a tablet. For example, a device that can be folded into two layers typically includes a first structural member and a second structural member. The first and second structural members are hingedly connected, allowing the first and second structural members to rotate relative to each other, thereby achieving folding or unfolding between the first and second structural members. Flexible screens are provided on the first and second structural members. The flexible screens bend as the first and second structural members are folded, and unfold as the first and second structural members are unfolded, thereby expanding the display screen of the electronic device.

[0078] However, whether it is a two-layer foldable screen mobile phone or a three-layer foldable screen mobile phone, after one unfolding operation, the flexible screen area can only be expanded to twice the original flexible screen area at most, that is, the display area can only be expanded to double at most. The display area needs to be further improved to improve user experience and display effects.

[0079] Based on the above technical problems, an embodiment of the present application provides a folding side-pull device and an electronic device. The folding side-pull device includes a first structural member and a second structural member, and the first structural member and the second structural member are rotatably connected by a folding mechanism, thereby realizing the folding and unfolding between the first structural member and the second structural member. It also includes a first side pull member, which is slidably connected to the second structural member. The flexible screen can be set on the first surface of the first side pull member (the side close to the display surface). When the first side pull member slides in a direction close to the second structural member, part of the flexible screen is wrapped around the first side pull member. When the first side pull member slides in a direction away from the second structural member, the flexible screen wrapped around the first side pull member is unfolded on the first surface of the first side pull member. In this way, when the first structural member and the second structural member move toward each other, the first side pull member can slide toward the second structural member, and part of the flexible screen can be wrapped around the first side pull member. When the first structural member and the second structural member move away from each other, the first side pull member can slide away from the second structural member, so that the distance between the second structural member and the first side pull member is lengthened, and the flexible screen originally wrapped around the first side pull member is unfolded on the first side pull member, thereby expanding the total size area of ​​the flexible screen located on the second structural member and the first side pull member. That is, while the first structural member and the second structural member are folded to unfolded, the size of the unfolded flexible screen is expanded by sliding the first side pull member, so that the area of ​​the flexible screen after one unfolding operation is doubled or more, effectively increasing the area of ​​the display area, improving the user experience and screen display effect.

[0080] The electronic devices may include, but are not limited to, foldable fixed or mobile terminals such as mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), handheld computers, touch-screen TVs, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, and virtual reality devices.

[0081] For example, the electronic device 10 may be a foldable screen mobile phone, see Figure 1 As shown, the foldable screen mobile phone may include a first structural member 11, a second structural member 12 and a folding mechanism 13. The first structural member 11 and the second structural member 12 are rotatably connected by the folding mechanism 13 so that the first structural member 11 and the second structural member 12 can be folded or unfolded with each other.

[0082] When the first structural member 11 and the second structural member 12 rotate toward each other and overlap each other, the folding screen mobile phone is in a folded state (eg Figure 4 As shown), on the contrary, when the first structural member 11 and the second structural member 12 are rotated from the stacked state to the back until the first structural member 11 and the second structural member 12 cannot rotate (such as the first structural member 11 and the second structural member 12 are on the same plane), the foldable screen mobile phone is in the unfolded state (such as Figure 6 The process of the first structural member 11 and the second structural member 12 rotating toward each other to a stacked state is the process of folding the first structural member 11 and the second structural member 12, and the process of the first structural member 11 and the second structural member 12 rotating away from each other to an unfolded state is the process of unfolding the first structural member 11 and the second structural member 12.

[0083] The electronic device may also be a laptop computer, which may also include a first structural member, a second structural member, and a folding mechanism. When the first structural member and the second structural member are rotated toward each other to be stacked, the laptop computer is in a folded state. Conversely, when the first structural member and the second structural member are rotated away from each other to the point where they cannot rotate, the laptop computer is in an unfolded state.

[0084] In the embodiment of the present application, a foldable screen mobile phone is taken as the above-mentioned electronic device, and the foldable screen mobile phone can be folded into two layers as an example for specific description.

[0085] See also Figure 1 and 2 As shown, the electronic device 10 includes a flexible screen 14 and a folding side-pull device, at least part of the flexible screen 14 is arranged on the first surface of the folding side-pull device. Specifically, the electronic device 10 has a display surface for displaying images and a shell surface opposite to the display surface. The first surface is a side of the folding side-pull device close to the display surface, and the second surface opposite to the first surface is a side close to the shell surface.

[0086] Among them, the folding side-pull device includes a first structural member 11, a second structural member 12, a folding mechanism 13 and a first side-pull member 17. The first structural member 11 and the second structural member 12 are rotatably connected through the folding mechanism 13. Specifically, the first structural member 11 is rotatably connected to the folding mechanism 13, and the second structural member 12 is rotatably connected to the folding mechanism 13, so that the first structural member 11 and the second structural member 12 can rotate relative to each other, thereby realizing relative folding or unfolding between the first structural member 11 and the second structural member 12. At the same time, the flexible screen 14 located on the first structural member 11 and the second structural member 12 will also bend or unfold accordingly.

[0087] The first side pull member 17 is slidably connected to the end of the second structural member 12 away from the folding mechanism 13. Specifically, Figure 2 As shown, the first structural member 11 and the second structural member 12 move away from each other, that is, during the unfolding process, the first side pull member 17 can slide in a direction away from the second structural member 12, so that the distance between the first side pull member 17 and the second structural member 12 is lengthened. When the first structural member 11 and the second structural member 12 are in the unfolded state, the overall size of the second structural member 12 and the first side pull member 17 can be larger than the size of the first structural member 11. The first structural member 11 and the second structural member 12 move toward each other, that is, during the folding process, the first side pull member 17 can slide in a direction close to the second structural member 12, so that the distance between the first side pull member 17 and the second structural member 12 is shortened. When the first structural member 11 and the second structural member 12 are in the folded state, the overall size of the second structural member 12 and the first side pull member 17 can be consistent with the size of the first structural member 11.

[0088] The flexible screen 14 can be provided on the first structural member 11, the second structural member 12, the folding mechanism 13 and the first side pull member 17. The first side pull member 17 is used to slide in a direction close to the second structural member 12 so that part of the flexible screen 14 is wrapped around the first side pull member 17. Specifically, when the first side pull member 17 slides in a direction close to the second structural member 12, the edge of the flexible screen 14 located on the first surface of the first side pull member 17 bends at the edge of the first side pull member 17 away from the second structural member 12 as the first side pull member 17 slides and extends to the second surface of the first side pull member 17. The first side pull member 17 is also used to slide in a direction away from the second structural member 12 so that the flexible screen 14 wrapped around the first side pull member 17 is unfolded on the first side pull member 17.

[0089] Specifically, the flexible screen 14 can be slidably arranged with the first side pull member 17, and part of the flexible screen 14 can be arranged on the first surface of the first side pull member 17 (the side close to the display surface). When the first side pull member 17 slides toward the second structural member 12, the flexible screen 14 will also slide relative to the first side pull member 17. The edge of part of the flexible screen 14 can bend along the edge of the first side pull member 17 away from the second structural member 12 and slide to the second surface of the first side pull member 17 (the side opposite to the first surface), thereby being wrapped around the first side pull member 17.

[0090] It should be noted that when the flexible screen 14 is large in size, when the first structural member 11 and the second structural member 12 move toward each other, the edge of part of the flexible screen 14 can bend and slide along the edge of the first side pull member 17 away from one end of the second structural member 12 to extend to the second surface of the first side pull member 17 and the second structural member 12.

[0091] See also Figure 2 As shown, when the first side member 17 slides away from the second structural member 12, the flexible screen 14 slides relative to the first side member 17, causing the flexible screen 14 wrapped around the first side member 17 to unfold on the first surface of the first side member 17. Thus, when the first structural member 11 and the second structural member 12 move away from each other, the first side member 17 slides away from the second structural member 12, causing the distance between the second structural member 12 and the first side member 17 to lengthen. The flexible screen 14, which was originally wrapped around the first side member 17 in a folded state, unfolds on the first side member 17, thereby expanding the total size of the flexible screen located on the second structural member 12 and the first side member 17. Specifically, as the first structural member 11 and the second structural member 12 move from folded to unfolded, the size of the unfolded flexible screen 14 expands, resulting in an area of ​​the flexible screen 14 doubled or more after a single unfolding operation. This effectively increases the display area and improves the user experience and screen display quality.

[0092] The first side pull member 17 is slidably connected to the end of the second structural member 12 away from the folding mechanism 13. Specifically, the end of the second structural member 12 can be slidably mounted in the first side pull member 17 to achieve sliding between the second structural member 12 and the first side pull member 17, or the end of the second structural member 12 can also be slidably mounted on the outer periphery of the first side pull member 17 to achieve sliding between the second structural member 12 and the first side pull member 17.

[0093] It should be noted that, in the folded state, the size of the display area formed by the flexible screen 14 located on the first structural member 11 or the second structural member 12 and the first side pull member 17 can meet the normal usage needs of the user. For example, the diagonal length of the display area formed by the flexible screen 14 on the first structural member 11 can be 6.62, 6.67 inches, etc. When the first structural member 11 and the second structural member 12 are in the unfolded state, the first structural member 11, the second structural member 12 and the flexible screen 14 on the first side pull member 17 can jointly form a display area. At the same time, the first side pull member 17 slides away from the second structural member 12, so that the size area of ​​the flexible screen 14 on the first side pull member 17 and the second structural member 12 becomes larger, so that the size of the formed display area can reach more than twice the original size area.

[0094] In the embodiment of the present application, when the first structural member 11 and the second structural member 12 move toward each other, the first side pull member 17 can be triggered to slide toward the second structural member 12. When the first structural member 11 and the second structural member 12 move away from each other, the first side pull member 17 can be triggered to slide away from the second structural member 12. This triggering can be manual or automatic.

[0095] See also Figure 3 As shown, in the embodiment of the present application, specifically, the electronic device 10 may further include a side-pull mechanism 15 and a linkage mechanism 16. The side-pull mechanism 15 is connected to the first side-pull member 17. The side-pull mechanism 15 is used to drive the first side-pull member 17 to slide toward or away from the first structural member 11. The side-pull mechanism 15 and the folding mechanism 13 are connected through the linkage mechanism 16. The linkage mechanism 16 is used to drive the side-pull mechanism 15 to make the first side-pull member 17 slide toward the second structural member 12 when the first structural member 11 and the second structural member 12 move toward each other. The linkage mechanism 16 is used to drive the side-pull mechanism 15 to make the first side-pull member 17 slide toward the second structural member 12 when the first structural member 11 and the second structural member 12 move away from each other.

[0096] Specifically, when the first structural member 11 and the second structural member 12 rotate toward each other, the linkage mechanism 16 drives the side pulling mechanism 15, causing the side pulling mechanism 15 to drive the first side pulling member 17 to slide closer to the second structural member 12, and a portion of the flexible screen 14 is wound around the first side pulling member 17. When the first structural member 11 and the second structural member 12 rotate away from each other, the linkage mechanism 16 drives the side pulling mechanism 15, causing the side pulling mechanism 15 to drive the first side pulling member 17 to slide away from the second structural member 12, and the flexible screen 14 wound around the first side pulling member 17 is unfolded on the first side pulling member 17.

[0097] In the examples of this application, see Figures 4 to 6As shown, the folding mechanism 13 includes a main shaft 131 and a first rotating member 132, one end of the first rotating member 132 is rotatably connected to the main shaft 131, and the other end of the first rotating member 132 is slidably connected to the second structural member 12. The first rotating member 132 is rotatable relative to the main shaft 131, and can drive the second structural member 12 to rotate relative to the main shaft 131. While rotating, one end of the first rotating member 132 can slide toward the end of the second structural member 12 close to the main shaft 131 or toward the end of the second structural member 12 away from the main shaft 131, that is, the first rotating member 132 and the second structural member 12 slide relative to each other, generating a first sliding displacement.

[0098] Among them, combined Figure 7 As shown, one end of the linkage mechanism 16 can be connected to the first rotating member 132, and the other end of the linkage mechanism 16 is connected to the side pulling mechanism 15. In this way, when the first structural member 11 and the second structural member 12 rotate, the first rotating member 132 and the second structural member 12 will slide relative to each other to generate a first sliding displacement. The linkage mechanism 16 can drive the side pulling mechanism 15 through the first sliding displacement, so that the side pulling mechanism 15 drives the first side pulling member 17 to slide, thereby realizing the conversion between angular velocity and linear velocity.

[0099] Specifically, such as Figure 7 and Figure 8 As shown, the side-pull mechanism 15 can be a side-pull link, and the linkage mechanism 16 can include an input link 161 and a displacement amplifier 162. The input link 161 is fixedly connected to the first rotating member 132, and the first sliding displacement of the first rotating member 132 is transmitted to the input link 161. The input link 161 is connected to the side-pull link through the displacement amplifier 162, that is, the other end of the input link 161 is connected to the displacement amplifier 162, the displacement amplifier 162 is connected to the side-pull link, and the side-pull link is connected to the first side-pull member 17.

[0100] The displacement amplifier is used to amplify the first sliding displacement of the input link 161 relative to the second structural member 12 into a second sliding displacement. The second sliding displacement is output to the first side pull member 17 through the side pull link, so that the side pull link drives the first side pull member 17 to slide relative to the second structural member 12 with the second sliding displacement. Due to the change in the rotation angle between the first structural member 11 and the second structural member 12, the displacement of the first rotating member 132 is smaller, so that the displacement that drives the first side pull member 17 to slide is limited. The first sliding displacement generated between the first rotating member 132 and the second structural member 12 is amplified by the displacement amplifier to the second sliding displacement to drive the side pull mechanism 15, and the first side pull member 17 is driven to slide through the side pull mechanism 15 to ensure that the rotation of the first structural member 11 and the second structural member 12 causes the displacement generated by the first rotating member 132 to well drive the first side pull member 17 to slide relative to the second structural member 12.

[0101] For example, when the first structural member 11 and the second structural member 12 move away from each other, the first rotating member 132 slides toward the end of the second structural member 12 away from the main shaft 131, passes through the input connecting rod 161 and the displacement amplifier 162, and drives the first side member 17 to slide away from the second structural member 12. When the first structural member 11 and the second structural member 12 move toward each other, the first rotating member 132 slides toward the end of the second structural member 12 closer to the main shaft 131, passes through the input connecting rod 161 and the displacement amplifier 163, and drives the first side member 17 to slide toward the second structural member 12.

[0102] It should be understood that, every time the first structural member 11 and the second structural member 12 rotate by an angle, the first rotating member 132 will undergo a fixed displacement change, thereby driving the first side pulling member 17 to undergo a corresponding displacement and sliding.

[0103] Among them, in a possible implementation, such as Figure 8 As shown, the displacement amplifier 162 may include a driving gear 1621 and a driven gear 1622, the driving gear 1621 and the driven gear 1622 are coaxially arranged, the radius of the driving gear 1621 is smaller than the radius of the driven gear 1622, and a rack is provided on the side opposite to the driving gear 1621 of the input connecting rod 161, the driving gear 1621 and the rack of the input connecting rod 161 are meshed with each other, and a rack is provided on the side opposite to the driven gear 1622 of the side pulling connecting rod, the driven gear 1622 and the rack of the side pulling connecting rod are meshed with each other, and the first sliding displacement between the first rotating member 132 and the second structural member 12 drives the driving gear 1621 with a smaller radius to rotate through the input connecting rod 161, and the driving gear 1621 drives the driven gear 1622 with a larger radius to rotate, thereby amplifying the first sliding displacement into a second sliding displacement, and the driven gear 1622 drives the side pulling connecting rod to perform a second sliding displacement, thereby driving the first side pulling member 17 to slide relative to the second structural member 12 with the second displacement.

[0104] In another possible implementation, the displacement amplifier may include at least two gear assemblies, each gear assembly includes a driving gear and a driven gear, the driving gear and the driven gear in each gear assembly are coaxially arranged, the radius of the driving gear in each gear assembly is smaller than the radius of the driven gear, and multiple gear assemblies are connected in series. Specifically, in two gear assemblies in series, the driving gear of one gear assembly is meshed with the driven gear of the other gear assembly.

[0105] The input link 161 and the side pull link are provided with racks on the side opposite the gear assembly. The driving gear of one gear assembly meshes with the rack of the input link 161, while the driven gear of the other gear assembly meshes with the rack of the side pull link. Multiple gear assemblies can increase the magnification of the first sliding displacement, better ensuring that the rotation of the first structural member 11 and the second structural member 12 causes the displacement of the first rotating member 132 to drive the first side pull member 17 to slide relative to the second structural member 12. This also allows the first side pull member 17 to slide a greater distance relative to the second structural member 12, helping to meet the demand for a larger size of the flexible screen after deployment.

[0106] See also Figure 9 As shown, in the embodiment of the present application, the first structural member 11 and the second structural member 12 can be manually rotated to unfold or fold. Since the rotation angle between the first structural member 11 and the second structural member 12 changes, the first rotating member 132 slides relative to the second structural member 12, thereby driving the first side pull member 17 to move, realizing automatic triggering of the movement of the first side pull member 17, that is, the sliding of the first side pull member 17 is realized while rotating, and the first side pull member 17 undergoes a fixed trigger displacement for each rotation angle.

[0107] In the examples of this application, see Figure 10 As shown, the electronic device 10 further includes a screen traction mechanism 18, which is disposed within the first side member 17. The screen traction mechanism is configured to cause the flexible screen 14 to slide relative to the first side member 17 and to be wound around the first side member 17 when the first side member 17 slides toward the second structural member 12. The screen traction mechanism 18 is also configured to cause the flexible screen 14 to slide relative to the first side member 17 and to be unfolded on the first side member 17 when the first side member 17 slides away from the second structural member 12. The screen traction mechanism 18 can pull the flexible screen 14 to slide, facilitating its sliding. It can also ensure that the sliding of the first side member 17 and the sliding of the flexible screen 14 are synchronized, preventing damage to the flexible screen 14 caused by improper force applied to the flexible screen 14 due to asynchronous sliding.

[0108] For details, see Figure 11 As shown, the screen traction mechanism 18 may include a first transmission belt 181, a first gear 182 and a second gear 183 arranged opposite to each other, and a second transmission belt 184 wound around the first gear 182 and the second gear 183, wherein the first transmission belt 181 is arranged between at least the first side pull member 17 and the flexible screen 14, such as the first structural member 11, the second structural member 12, and the first side pull member 17 and the flexible screen 14. The first transmission belt 181 is fixed to the second structural member 12, and the first gear 182 and the second gear 183 are rotatably arranged in the first side pull member 17.

[0109] One of the two opposite surfaces of the first transmission belt 181 and the second transmission belt 184 has a groove, and the other surface has a protrusion that cooperates with the groove. The first transmission belt 181 and the second transmission belt 184 are engaged and connected by the groove and the protrusion. The opposite side of the first transmission belt 181 and the second transmission belt 184 is used to fit the flexible screen.

[0110] When the first side member 17 slides, the first transmission belt 181 drives the first gear 182 and the second gear 183 to rotate through the second transmission belt 184, causing the first transmission belt 181 and the first side member 17 to slide relative to each other, thereby pulling the flexible screen 14 attached to the first transmission belt 181 to slide synchronously, improving the sliding performance of the flexible screen 14 and facilitating the winding or unfolding of the flexible screen 14 on the first side member 17 as the first side member 17 slides. At the same time, the flexible screen 14 is attached to the first transmission belt 181, and the first transmission belt 181 is engaged with the second transmission belt 184. The screen traction mechanism 18 plays a certain role in limiting the position of the flexible screen 14 during the winding and unfolding process, thereby reducing the occurrence of problems such as protrusions 185 or curling of the flexible screen 14 during the winding or unfolding process.

[0111] See also Figure 12 As shown, the first transmission belt 181 can be a rigid bendable structural member, see Figure 13 As shown, the flexible screen 14 is fitted on the rigid bendable structure. The rigid bendable structure may have a plurality of protrusions 185 arranged in parallel on the side away from the flexible screen 14 . The rigid bendable structure engages with the grooves on the second transmission belt 184 through the protrusions 185 .

[0112] A guide rail 171 may be provided on the side of the first side member 17 away from the flexible screen 14, and the rigid bendable structure slides within the guide rail 171. When the first side member 17 slides, the rigid bendable structure slides within the guide rail 171, pulling the flexible screen 14 along. At the same time, the rigid bendable structure provides a certain degree of rigid support for the flexible screen 14, further reducing the occurrence of problems such as bulging or curling of the flexible screen 14 during winding or unfolding.

[0113] Among them, see Figure 14 As shown, a rigid bendable structure can be provided under the entire flexible screen 14 to provide rigid support for the flexible screen 14 and help improve the mechanical properties of the flexible screen 14.

[0114] The electronic device 10 provided in the embodiment of the present application can be folded inwards, specifically, Figure 15As shown, the folding mechanism 13 can also include a second rotating member 133, one end of the second rotating member 133 is rotatably connected to the main shaft 131, and the other end is slidably connected to the first structural member 11. The first structural member 11 is rotatably connected to the main shaft 131 through the second rotating member 133. When the first structural member 11 and the second structural member 12 are in a folded state, the flexible screen 14 is bent and arranged between the first structural member 11 and the second structural member 12, wherein the part of the flexible screen 14 corresponding to the folding mechanism 13 is bent when folded, so that the first rotating member 132 and the second rotating member 133 can enclose a accommodating space for the flexible screen 14, so that the flexible screen 14 is bent and arranged in the accommodating space, which can meet the accommodating requirements of the flexible screen after folding, and can reduce the occurrence of excessive squeezing of the flexible screen during folding.

[0115] like Figure 16 As shown, when the first structural member 11 and the second structural member 12 are in the unfolded state, the flexible screen 14 is unfolded and laid on the first structural member 11, the first rotating member 132, the second rotating member 133 and the second structural member 12. Figure 5 and Figure 6 As shown, when the first structural member 11 and the second structural member 12 move away from each other, the first rotating member 132 slides relative to the first structural member 11, and the first rotating member 132 slides toward the end of the first structural member 11 away from the main shaft 131, so that the first structural member 11 rotates with the main shaft 131, and the end of the first structural member 11 away from the flexible screen 14 moves toward the main shaft 131, so that part of the main shaft 131 is located in the first structural member 11, and accordingly, the end of the second structural member 12 away from the flexible screen 14 also moves toward the main shaft 131, so that Another part of the main shaft 131 is located in the second structural member 12. When the first structural member 11 and the second structural member 12 are unfolded, the end of the first structural member 11 away from the flexible screen 14 and the end of the second structural member 12 away from the flexible screen 14 will abut against each other. At the same time, the main shaft 131 is located in the first structural member 11 and the second structural member 12. In this way, the main shaft 131 is hidden by the first structural member 11 and the second structural member 12, thereby improving the integrity of the external shell of the electronic device 10 after unfolding, and improving the aesthetics and waterproof and dustproof performance of the electronic device 10.

[0116] In addition, due to the relative sliding between the first rotating member 132 and the first structural member 11, the end of the first structural member 11 away from the flexible screen 14 moves toward the main shaft 131 while the first structural member 11 rotates with the main shaft 131, and the end of the first structural member 11 close to the flexible screen 14 basically does not produce displacement during the rotation process. Correspondingly, the end of the second structural member 12 close to the flexible screen 14 basically does not produce displacement during the rotation process, that is, during the rotation process, the distance from the end of the second structural member 12 close to the flexible screen 14 to the end of the first side pulling member 17 close to the flexible screen 14 remains basically unchanged, so that the foldable When in the folded state and the unfolded state, the length of the first structural member 11 and the second structural member 12 close to the flexible screen 14 (the length of the fitting line formed by the connecting lines of the first structural member away from the main axis, the main axis and the second structural member away from the main axis close to the flexible screen) remains basically unchanged, so that the flexible screen 14 in the bent part can maintain a constant length L, so that the length of the flexible screen 14 in the folded state is equal to the length of the flexible screen 14 in the unfolded state, so that the flexible screen 14 will not be subjected to pulling force during the rotation of the first structural member 11 and the second structural member 12, thereby effectively improving the service life of the flexible screen 14.

[0117] Among them, a certain distance can be set between the first rotating member 132 and the second rotating member 133 to ensure that the first rotating member 132 and the second rotating member 133 can form a larger accommodating space to avoid the flexible screen 14 being damaged due to dead folding during the folding process.

[0118] The folding form of the electronic device 10 can also be outward folding. Specifically, when the first structural member 11 and the second structural member 12 are folded, the flexible screen 14 can be bent and arranged on the outer periphery of the first structural member 11 and the second structural member 12. Figure 17 As shown, when the first structural member 11 and the second structural member 12 are folded, part of the flexible screen 14 is wrapped around the second surface of the first side pull member 17 (the side away from the display surface of the electronic device). When the first structural member 11 and the second structural member 12 move away from each other, the first side pull member 17 slides away from the second structural member 12, and the flexible screen 14 also unfolds on the first surface of the first side pull member 17 (the side close to the display surface) as it slides.

[0119] In the examples of this application, see Figure 18 As shown, the folding side pulling device may further include a second side pulling member 19, which is slidably connected to the first structural member 11. The second side pulling member 19 can slide toward or away from the first structural member 11. Specifically, when the first structural member 11 and the second structural member 12 move in opposite directions, as shown in FIG. Figure 19As shown, the second side pull member 112 can slide in a direction away from the first structural member 11. When the first structural member 11 and the second structural member 12 move toward each other, the second side pull member 19 can slide in a direction close to the first structural member 11.

[0120] The second side pull member 19 is used to support the flexible screen 14, that is, the flexible screen 14 is arranged on the second side pull member 19, and the second side pull member 19 is used to slide in the direction close to the first structural member 11 so that part of the flexible screen 14 is wound on the second side pull member. The second side pull member is also used to slide in the direction away from the first structural member 11 so that the wound flexible screen 14 is unfolded on the second side pull member 19.

[0121] Specifically, the flexible screen 14 can be slidably arranged with the second side pull member 19, and the flexible screen 14 is arranged on the first surface (the side close to the display surface) of the second side pull member 19, such as Figure 19 As shown, when the second side pull member 19 slides toward the first structural member 11, the flexible screen 14 will also slide relative to the second side pull member 19, and the edge of part of the flexible screen 14 can bend along the edge of the second side pull member 19 away from the first structural member 11 and slide to the second surface of the second side pull member 19 (the side opposite to the first surface), thereby being wrapped around the second side pull member 19.

[0122] When the second side member 19 slides in a direction away from the first structural member 11, the flexible screen 14 slides relative to the second side member 19, causing the flexible screen 14 wrapped around the second side member 19 to unfold on the first surface of the second side member 19. In this way, when the first structural member 11 and the second structural member 12 move away from each other, the second side member 19 slides away from the first structural member 11, causing the distance between the first structural member 11 and the second side member 19 to lengthen. The flexible screen 14, which was originally wrapped around the second side member 19 in a folded state, unfolds on the second side member 19, thereby expanding the total size of the flexible screen located on the first structural member 11 and the second side member 19, further expanding the size of the unfolded flexible screen 14, so that the area of ​​the flexible screen 14 increases more after a single unfolding operation, further increasing the display area and meeting the user's demand for large-size display.

[0123] Among them, a side-pull mechanism 15 and a linkage mechanism 16 may also be provided in the first structural member 11. The side-pull mechanism 15 is used to drive the second side-pull member 19 to slide toward or away from the first structural member 11. The side-pull mechanism 15 and the folding mechanism 13 are connected through the linkage mechanism 16. The linkage mechanism 16 is used to drive the side-pull mechanism to drive the second side-pull member 19 to slide toward the first structural member 11 when the first structural member 11 and the second structural member 12 move toward each other. The linkage mechanism 16 is also used to drive the side-pull mechanism to drive the second side-pull member 19 to slide away from the first structural member 11 when the first structural member 11 and the second structural member 12 move away from each other. The structure and connection drive method of the side-pull mechanism 15 and the linkage mechanism 16 can be the same as those of the side-pull mechanism 15 and the linkage mechanism 16 in the second structural member 12.

[0124] Example 2

[0125] The embodiment of the present application provides a folding side pull device, which is different from the embodiment 1 in that: Figure 20 As shown, there is a rotation angle between the first structural member 11 and the second structural member 12 , and the linkage mechanism 16 is a control module, which is used to drive the side pulling mechanism 15 to drive the first side pulling member 17 to slide according to the change of the rotation angle.

[0126] Specifically, the folding mechanism 13 may include an angle detection device (not shown) for detecting the rotation angle between the first structural member 11 and the second structural member 12. The angle detection device is connected to the control module, which is in turn connected to the side-pull mechanism 15. When the first structural member 11 and the second structural member 12 rotate, the angle detection device can detect the rotation angle between the first structural member 11 and the second structural member 12 and send this angle value to the control module. The control module converts the angle value into a corresponding sliding distance and sends this sliding distance value to the side-pull mechanism 15. After receiving the sliding distance value from the control module, the side-pull mechanism 15 controls the first side-pull member 17 to slide a corresponding distance relative to the second structural member 12, thereby automatically triggering the sliding of the first side-pull member 17 relative to the second structural member 12 while rotating the first structural member 11 and the second structural member 12.

[0127] The linkage mechanism 16 drives the side pull mechanism 15 according to the change of the rotation angle between the first structural member 11 and the second structural member 12. For details, see Figure 21 As shown, there is a rotation angle α between the first structural member 11 and the second structural member 12 , and the linkage mechanism 16 can drive the side pulling mechanism 15 to drive the first side pulling member 17 to slide according to the change in the angle value of the rotation angle α.

[0128] In one possible implementation, Figure 21As shown, when the rotation angle α changes to a preset angle value, the linkage mechanism 16 drives the side pulling mechanism 15 to drive the first side pulling member 17 to slide a corresponding distance, that is, each rotation angle corresponds to a fixed sliding distance, and the rotation angle and the sliding distance correspond one to one.

[0129] For example, when the first structural member 11 and the second structural member 12 rotate 30°, that is, the rotation angle α changes by 30°, the linkage mechanism 16 drives the side pulling mechanism 15 to cause the first side pulling member 17 to slide 30mm. For every 30° rotation of the first structural member 11 and the second structural member 12, the linkage mechanism 16 drives the side pulling mechanism 15 to cause the first side pulling member 17 to slide 30mm. Alternatively, when the first structural member 11 and the second structural member 12 rotate 100°, that is, the rotation angle α changes by 100°, the linkage mechanism 16 can drive the side pulling mechanism 15 to cause the first side pulling member 17 to slide 100mm.

[0130] In another possible implementation, Figure 22a and Figure 22b As shown, when the rotation angle α is within the preset angle range, the linkage mechanism 16 drives the side pulling mechanism 15 to drive the first side pulling member 17 to slide, that is, only when the rotation angle α is within the preset angle range can the first side pulling member 17 be triggered to slide relative to the second structural member 12. For example, Figure 22a As shown, when the first structural member 11 and the second structural member 12 move toward each other, the rotation angle α between the first structural member 11 and the second structural member 12 gradually decreases. When the value of the rotation angle α between the first structural member 11 and the second structural member 12 is within the range of less than 90° and greater than 0°, the linkage mechanism 16 can drive the side pulling mechanism 15 to cause the side pulling mechanism 15 to drive the first side pulling member 17 to slide toward the direction close to the second structural member 12. Or, as Figure 22b As shown, when the first structural member 11 and the second structural member 12 move away from each other, the rotation angle α between the first structural member 11 and the second structural member 12 gradually increases. When the value of the rotation angle α is within the range of greater than 90° and less than 180°, the linkage mechanism 16 can drive the side pulling mechanism 15, so that the side pulling mechanism 15 drives the first side pulling member 17 to slide in the direction away from the second structural member 12.

[0131] When the rotation angle is within a preset range, the linkage mechanism 16 drives the side-pull mechanism 15 to slide the first side-pull member 17. The sliding distance can correspond to the change in the rotation angle, for example, 10 mm for every 10° of rotation. Alternatively, there can be no corresponding relationship. For example, when the rotation angle ranges from 90° to 0°, the side-pull mechanism 15 can cause the first side-pull member 17 to slide a certain distance at any selected angle.

[0132] In another possible implementation, the linkage mechanism 16 can drive the side-pull mechanism 15 according to the change of the rotation angle between the first structural member 11 and the second structural member 12 and the rotation direction, so that the side-pull mechanism 15 drives the first side-pull member 17 to slide. Figure 23a and Figure 23b As shown, when the first structural member 11 and the second structural member 12 move away from each other, the rotation angle changes from the first preset angle value to the second preset angle value (such as Figure 23a When the first structural member 11 and the second structural member 12 move toward each other, the rotation angle changes from the third preset angle value to the fourth preset angle value (such as Figure 23b When the first side member 17 is rotated from 180° to 135° to form a rotation displacement of Y°, the linkage mechanism 16 drives the side pulling mechanism 15, so that the side pulling mechanism 15 drives the first side pulling member 17 to slide in a direction away from the second structural member 12.

[0133] The sliding distance of the first side pull member 17 may correspond to the change in the rotation angle, such as 10 mm for every 10° of rotation. Alternatively, there may be no corresponding relationship, such as the side pull mechanism 15 driving the first side pull member 17 to slide at arbitrarily selected angles.

[0134] Among them, in the examples of this application, see Figure 24 As shown, the side pulling mechanism 15 may include a shaft 151, a driver 152 and a pushing member 153. The shaft 151 and the driver 152 are fixed on the second structural member 12. One end of the pushing member 153 is fixed to the first side pulling member 17. The other end of the pushing member 153 is wrapped around the shaft 151. The driver 152 is connected to the shaft 151 to drive the shaft 151 to rotate, and the control module is connected to the driver 152.

[0135] When the control module generates a corresponding sliding distance based on the rotation angle value, the sliding distance information is sent to the driver 152. The driver 152 drives the shaft 151 to rotate according to the sliding distance. The pushing member 153 located on the shaft 151 will also extend or contract as the shaft 151 rotates, and then the pushing member 153 pushes the first side pulling member 17 to slide toward or away from the second structural member 12.

[0136] Alternatively, see Figure 25As shown, the side pulling mechanism 15 may include a fixed member 154, a telescopic member 155, and a movable member 156, wherein the fixed member 154 is disposed on the second structural member 12, the fixed member 154 and the movable member 156 are connected via the telescopic member 155, the movable member 156 is connected to the first side pulling member 17, and the control module is connected to the telescopic member 155 to drive the telescopic member 155 to retract. The control module may send a corresponding sliding distance to the telescopic member 155, driving the telescopic member 155 to drive the movable member 156 to move a corresponding distance, thereby driving the first side pulling member 17 to slide a corresponding distance toward or away from the second structural member 12 via the movable member 156.

[0137] In the examples of this application, see Figure 26 As shown, the electronic device 10 may further include a drive button 100. Specifically, the drive button 100 may be disposed on the outer frame of the electronic device 10. The drive button 100 is connected to a control module. The folding mechanism may also include a driver for driving the first structural member 11 and the second structural member 12 to rotate. The control module is connected to the driver. The drive button 100 is configured to receive a drive command from a user. Upon receiving the drive command, the control module controls the driver to drive the first structural member 11 and the second structural member 12 to rotate, thereby folding or unfolding the first structural member 11 and the second structural member 12. Simultaneously, the control module receives the angle value sent by the angle detection device and generates a sliding distance value, which drives the side pull mechanism 15 to push the first side pull member 17 to slide. Thus, when in use, the user does not need to manually drive the first structural member 11 and the second structural member 12 to rotate. Instead, the user only needs to operate the drive button 100 (e.g., by pressing, pushing, pulling, or fingerprint recognition) to fold or unfold the first structural member 11 and the second structural member 12. During the folding or unfolding process, the first side pull member 17 and the second structural member 12 are simultaneously triggered to slide relative to each other.

[0138] Among them, the driver of the folding mechanism and the first driver 152 of the side pulling mechanism can be the same driver, which can be used to drive the rotation between the first structural member 11 and the second structural member 12, and can also drive the first side pulling member 17 to slide according to the sliding data information of the control module.
