When the foldable electronic device in the folded state falls, the hinge mechanism is subjected to force to squeeze the folded portion of the display screen, making the display screen prone to cracking and bending, resulting in damage to the display screen, and affecting the service life of the electronic device. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an electronic device that can solve the problem in the related art that the display screen of a foldable electronic device is easily damaged when it falls.

For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0011] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0012] Please refer to Figure 1-Figure 16The electronic device disclosed in the embodiment of the present application includes a first device body 110, a second device body 120, a display screen 200, and a first adjustment mechanism 300. The first device body 110 and the second device body 120 are main components of the electronic device, and are used as a mounting base for the display screen 200 and the first adjustment mechanism 300. The first device body 110 and the second device body 120 can rotate relative to each other. Specifically, the first device body 110 and the second device body 120 can rotate relative to each other around a first axis, so that the electronic device can be switched between an unfolded state and a folded state.

[0013] The first part 210 of the display screen 200 is slidably connected to the first device body 110, and the second part 220 of the display screen 200 is connected to the second device body 120. Optionally, the first part 210 of the display screen 200 and the first device body 110 can be slidably connected through a matching slide rail and a slider, or can be slidably connected through other structures; the second part 220 of the display screen 200 can be fixedly connected to the second device body 120 by welding, bonding, etc., or the second part 220 of the display screen 200 and the second device body 120 can also be slidably connected through structures such as slide rails and sliders.

[0014] The electronic device has a folded state and an unfolded state. When the electronic device is in the folded state, the first device body 110 is opposite to the second device body 120, the display screen 200 is bent, and the first part 210 of the display screen 200 is opposite to the second part 220; when the electronic device is in the unfolded state, the first device body 110 and the second device body 120 are arranged side by side, and the display screen 200 is flattened, that is, the first part 210 and the second part 220 of the display screen 200 are located in the same plane.

[0015] The first adjustment mechanism 300 can automatically adjust the motion state of the first part 210 of the display screen 200. The first adjustment mechanism 300 includes a first pressure detection element 310 and a first driving member 320. The first pressure detection element 310 can be, but is not limited to, a pressure sensor. The first pressure detection element 310 is connected to the first part 210 of the display screen 200 to detect the pressure value of the display screen 200. The first driving member 320 is connected to the first part 210 of the display screen 200. Optionally, the first pressure detection element 310 and the first part 210 of the display screen 200 can be directly connected by welding, bonding, etc., or can be indirectly connected by connecting other components. Further, optionally, the first pressure detection element 310 is connected to the first part 210 of the display screen 200 through a first connecting glue 610.

[0016] When the electronic device is in a folded state and the pressure value detected by the first pressure detection element 310 reaches the pressure threshold, it means that the first part 210 of the display screen 200 is subjected to a large pressure value, that is, the display screen 200 is subjected to a large pressure value. At this time, the first driving member 320 drives the first part 210 of the display screen 200 to slide relative to the first device body 110 in a direction away from the first axis, so as to avoid the folded part of the display screen 200 from being violently hit, thereby causing the display screen 200 to crack and bend, and to avoid damage to the display screen 200, so as to avoid affecting the service life of the electronic device. When the pressure value detected by the first pressure detection element 310 does not reach the pressure threshold, it means that the first part 210 of the display screen 200 is not subjected to force or the pressure value is small. At this time, the first driving member 320 is not working, and the first part 210 of the display screen 200 is fixed relative to the first device body 110.

[0017] It should be noted that the user can set the pressure threshold as needed.

[0018] Optionally, the first axis extends along the length direction of the electronic device, so the direction away from the first axis can be the width direction of the electronic device; the first axis extends along the width direction of the electronic device, so the direction away from the first axis can be the length direction of the electronic device.

[0019] Specifically, refer to Figure 1 As shown, when the electronic device does not fall, the folded portion of the display screen 200 is not subjected to force, the pressure value detected by the first pressure detection element 310 is zero, the first driving member 320 is not working, and the first portion 210 of the display screen 200 is fixed relative to the first device body 110; Figure 3 As shown, when the electronic device falls, the folded part of the display screen 200 is subjected to force, and the first part 210 of the display screen 200 is also subjected to force, so the pressure value detected by the first pressure detection element 310 increases rapidly, and the first driving member 320 drives the first part 210 of the display screen 200 to slide, and the sliding direction is the direction away from the first axis, that is, the direction away from the hinge mechanism of the electronic device. Then, the folded part of the display screen 200 will avoid to reduce stress and prevent the display screen 200 from bending and cracking.

[0020] In an alternative embodiment, reference Figure 2 and Figure 4As shown, the electronic device further includes a first sliding member 400, the first device body 110 is provided with a first slide groove 101, the first sliding member 400 and the first slide groove 101 are slidably matched, the first part 210 of the display screen 200 is connected to the first sliding member 400, optionally, the first part 210 of the display screen 200 and the first sliding member 400 can be fixedly connected by welding, bonding, etc., further optionally, the first part 210 of the display screen 200 is fixedly connected to the first sliding member 400 by a first connecting glue 610, and the first sliding member 400 is provided with a mounting groove for mounting a pressure detection element, and the pressure detection element is also connected to the first part 210 of the display screen 200 by the first connecting glue 610. The first driving member 320 is arranged in the first slide groove 101, and the first driving member 320 can drive the first sliding member 400 to drive the first part 210 of the display screen 200 to slide along the first slide groove 101, and the extension direction of the first slide groove 101 is the direction away from the first axis.

[0021] Optionally, the first sliding member 400 may be a slider, a sliding bar, or the like, and the present embodiment does not limit the structure of the first sliding member 400; the first sliding groove 101 may also be a square groove, or the like, and the present embodiment does not limit the structure of the first sliding groove 101, refer to Figure 7 As shown, the surface of the first sliding member 400 matches with the groove wall surface of the first sliding groove 101 .

[0022] With this embodiment, the first part 210 of the display screen 200 is slidably matched with the first device body 110 through the first sliding member 400 and the first sliding groove 101. It is only necessary to add the first sliding member 400 and open the first sliding groove 101. There is no need to separately set up structures such as sliding rails and sliders. The sliding matching structure is simple, which is conducive to simplifying the structure of the electronic device.

[0023] In an alternative approach, refer to Figure 2 As shown, the first driving member 320 includes a first electromagnetic member 321 and a second electromagnetic member 322, wherein the first electromagnetic member 321 is connected to the first device body 110, and the second electromagnetic member 322 is connected to the first sliding member 400. Optionally, the first electromagnetic member 321 and the first device body 110 can be fixedly connected by welding, bonding, etc., and the second electromagnetic member 322 and the first sliding member 400 can be fixedly connected by welding, bonding, etc. The first electromagnetic member 321 and the second electromagnetic member 322 can both be, but not limited to, electromagnets, or other components that can generate a magnetic field when energized. When the first electromagnetic member 321 and the second electromagnetic member 322 are energized, the two can interact with each other, that is, the two can attract or repel each other.

[0024] When the electronic device is in the folded state and the pressure value detected by the first pressure detection element 310 reaches the pressure threshold, the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-on state, and the first electromagnetic member 321 and the second electromagnetic member 322 interact with each other to make the first sliding member 400 slide along the first slide groove 101. When the pressure value detected by the first pressure detection element 310 is less than the pressure threshold, the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-off state, and there is no interaction between the first electromagnetic member 321 and the second electromagnetic member 322, and the first sliding member 400 is fixed relative to the first slide groove 101.

[0025] Optionally, when the first electromagnetic component 321 and the second electromagnetic component 322 are both in the power-off state, the first electromagnetic component 321 and the second electromagnetic component 322 can be located at the same end of the first slide groove 101, that is, the first electromagnetic component 321 is in contact with the second electromagnetic component 322; when the first electromagnetic component 321 and the second electromagnetic component 322 are both in the power-on state, the first electromagnetic component 321 and the second electromagnetic component 322 repel each other, and the first electromagnetic component 321 and the second electromagnetic component 322 move away from each other, so that the first sliding component 400 slides along the first slide groove 101.

[0026] In this embodiment, magnetic force is used to drive the first sliding member 400 to slide, and there is no need to use complex driving structures such as linear modules and telescopic cylinders, which is beneficial to simplifying the structure of the first driving member 320. Moreover, the first electromagnetic member 321 and the second electromagnetic member 322 are relatively small in size, which is beneficial to reducing the volume of the first driving member 320 and simplifying the structure of the electronic device.

[0027] In this embodiment, when the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-off state, in the extension direction of the first slide groove 101, the first electromagnetic member 321 is located at the first end of the first slide groove 101, and the second electromagnetic member 322 is located at the second end of the first slide groove 101, that is, the first electromagnetic member 321 and the second electromagnetic member 322 are separated by a certain distance; when the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-on state, the first electromagnetic member 321 and the second electromagnetic member 322 attract each other, and the first electromagnetic member 321 and the second electromagnetic member 322 approach each other, so that the first sliding member 400 slides along the first slide groove 101 until the first electromagnetic member 321 contacts the second electromagnetic member 322 (refer to Figure 2 status shown).

[0028] In a further embodiment, reference Figure 4As shown, the first driving member 320 also includes a third electromagnetic member 323 and a fourth electromagnetic member 324, the third electromagnetic member 323 is connected to the first device body 110, and the fourth electromagnetic member 324 is connected to the first sliding member 400. Optionally, the third electromagnetic member 323 and the first device body 110 can be fixedly connected by welding, bonding, etc., and the fourth electromagnetic member 324 and the first sliding member 400 can be fixedly connected by welding, bonding, etc. The third electromagnetic member 323 and the fourth electromagnetic member 324 can be, but are not limited to, electromagnets, and can also be other components that can generate a magnetic field when powered on. When the third electromagnetic member 323 and the fourth electromagnetic member 324 are powered on, the two can interact with each other, that is, the two can attract or repel each other.

[0029] When the pressure value detected by the first pressure detection element 310 is less than the pressure threshold, the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-off state, and the third electromagnetic member 323 and the fourth electromagnetic member 324 are both in the power-on state, and the third electromagnetic member 323 and the fourth electromagnetic member 324 interact with each other to fix the first sliding member 400 relative to the first device body 110. When the electronic device is in the folded state and the pressure value detected by the first pressure detection element 310 reaches the pressure threshold, the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-on state, and the third electromagnetic member 323 and the fourth electromagnetic member 324 are both in the power-off state, and the first electromagnetic member 321 and the second electromagnetic member 322 interact with each other to slide the first sliding member 400 relative to the first device body 110. It should be noted that the force generated when the third electromagnetic member 323 and the fourth electromagnetic member 324 are both powered on is opposite to the force generated when the first electromagnetic member 321 and the second electromagnetic member 322 are both powered on.

[0030] Optionally, when the third electromagnetic component 323 and the fourth electromagnetic component 324 are both in the power-off state, in the extension direction of the first slide groove 101, the third electromagnetic component 323 is located at the first end of the first slide groove 101, and the fourth electromagnetic component 324 is located at the second end of the first slide groove 101, that is, the third electromagnetic component 323 and the fourth electromagnetic component 324 are separated by a certain distance; when the third electromagnetic component 323 and the fourth electromagnetic component 324 are both in the power-on state, the third electromagnetic component 323 and the fourth electromagnetic component 324 attract each other and are attracted together, and the third electromagnetic component 323 and the fourth electromagnetic component 324 are relatively fixed, so that the first sliding component 400 is fixed relative to the first device body 110. By adopting this embodiment, the magnetic force between the third electromagnetic component 323 and the fourth electromagnetic component 324 is utilized, which is beneficial to stably maintain the position of the first sliding component 400 and prevent the first sliding component 400 from moving relative to the first sliding groove 101 when the display screen 200 is not subjected to force or the force is relatively small; moreover, the third electromagnetic component 323 and the fourth electromagnetic component 324 are relatively small in size, which is beneficial to reducing the volume of the first driving component 320 and simplifying the structure of the electronic device.

[0031] In this embodiment, when the first electromagnetic member 321 and the second electromagnetic member 322 are both in the power-off state, the first electromagnetic member 321 is in contact with the second electromagnetic member 322; Figure 4 As shown, when the first electromagnetic component 321 and the second electromagnetic component 322 are both in the energized state, the first electromagnetic component 321 and the second electromagnetic component 322 repel each other, and the repulsive force acts on the first sliding component 400, so that the first sliding component 400 abuts against the groove wall of the first sliding groove 101, so that the first sliding component 400 is fixed relative to the first sliding groove 101.

[0032] Of course, in other embodiments, the first driving member 320 may not be provided with the third electromagnetic member 323 and the fourth electromagnetic member 324, and a friction structure may be provided between the first sliding member 400 and the groove wall surface of the first slide groove 101 to keep the first sliding member 400 and the first slide groove 101 relatively fixed when the first electromagnetic member 321 and the second electromagnetic member 322 are both powered off.

[0033] In a further embodiment, reference Figure 5 As shown, the first sliding member 400 is a rectangular structure, and the number of the first electromagnetic member 321, the second electromagnetic member 322, the third electromagnetic member 323 and the fourth electromagnetic member 324 can be multiple, the first electromagnetic members 321 are arranged at intervals, the second electromagnetic members 322 are arranged at intervals, the third electromagnetic members 323 are arranged at intervals, and the fourth electromagnetic members 324 are arranged at intervals, and the first electromagnetic members 321 correspond to the second electromagnetic members 322 one by one, and the third electromagnetic members 323 correspond to the fourth electromagnetic members 324 one by one.

[0034] Optionally, the first device body 110 is provided with two groups of matching third electromagnetic components 323 and fourth electromagnetic components 324 and four groups of matching first electromagnetic components 321 and second electromagnetic components 322, and the two groups of matching third electromagnetic components 323 and fourth electromagnetic components 324 are spaced apart in the width direction of the first device body 110, and in the length direction of the first device body 110, a group of matching first electromagnetic components 321 and second electromagnetic components 322 are provided on both sides of each group of matching third electromagnetic components 323 and fourth electromagnetic components 324.

[0035] By adopting this embodiment, magnetic forces are generated at different positions by multiple sets of coordinated first electromagnetic members 321 and second electromagnetic members 322, which can drive different positions of the first sliding member 400 to slide relative to the first slide groove 101, which is more conducive to the stable sliding of the first sliding member 400 relative to the first slide groove 101 when the first part 210 of the display screen 200 is subjected to a large force; magnetic forces are generated at different positions by multiple sets of coordinated third electromagnetic members 323 and fourth electromagnetic members 324, so that different positions of the first sliding member 400 are fixed relative to the first slide groove 101, which is more conducive to the stable and stationary state of the first sliding member 400 relative to the first slide groove 101 when the first part 210 of the display screen 200 is subjected to a small force.

[0036] In an optional embodiment, the electronic device may further include a control device, which may be a programmable controller, a single chip microcomputer, or the like that can play a control role. The control device is respectively connected to the first pressure detection element 310, the first electromagnetic component 321, the second electromagnetic component 322, the third electromagnetic component 323, and the fourth electromagnetic component 324 in communication, and the control device controls the power-on state of the first electromagnetic component 321, the second electromagnetic component 322, the third electromagnetic component 323, and the fourth electromagnetic component 324 according to the pressure value detected by the first pressure detection element 310. In this way, the control device is relied on to realize the communication connection between the first pressure detection element 310 and each electromagnetic component, and the power-on state of each electromagnetic component can be automatically controlled according to the pressure value detected by the first pressure detection element 310.

[0037] Optionally, refer to Figure 5 As shown, the first electromagnetic member 321, the second electromagnetic member 322, the third electromagnetic member 323 and the fourth electromagnetic member 324 can all be electromagnetic strips, and the electromagnetic strips extend along the extension direction of the first sliding member 400. In this way, the first electromagnetic member 321 and the second electromagnetic member 322 are strip structures, which generate magnetic forces at different positions, and can drive different positions of the first sliding member 400 to slide relative to the first slide groove 101, which is more conducive to the first sliding member 400 to slide stably relative to the first slide groove 101 when the first part 210 of the display screen 200 is subjected to a large force; the third electromagnetic member 323 and the fourth electromagnetic member 324 are strip structures, which generate magnetic forces at different positions, so that different positions of the first sliding member 400 are fixed relative to the first slide groove 101, which is more conducive to the first sliding member 400 to be stable and stationary relative to the first slide groove 101 when the first part 210 of the display screen 200 is subjected to a small force.

[0038] In another alternative, refer to Figure 8-Figure 14As shown, the first driving member 320 includes a deformation element 320a, and the deformation element 320a is respectively connected to the first device body 110 and the first sliding member 400. Optionally, the deformation element 320a and the first sliding member 400 can be connected by welding, bonding, etc., and the deformation element 320a and the first device body 110 can also be connected by welding, bonding, etc., and further optionally, the deformation element 320a and the first sliding member 400 are connected by a first connecting glue 610.

[0039] refer to Figure 8 As shown in the figure, when the pressure value detected by the first pressure detection element 310 is less than the pressure threshold, it means that the first part 210 of the display screen 200 is subjected to little or no force, the deformation element 320a is not deformed, and the first sliding member 400 is fixed relative to the first device body 110. When the electronic device is in the folded state and the pressure value detected by the first pressure detection element 310 reaches the pressure threshold, it means that the first part 210 of the display screen 200 is subjected to great force, and the deformation element 320a is deformed to drive the first sliding member 400 to slide relative to the first device body 110 until the first part 210 of the display screen 200 is folded. Fig.11 Status shown.

[0040] Optionally, the deformation element 320a can be an electrodeformable element, and the electrodeformable element can be a piezoelectric element, a shape memory alloy, etc. Further optionally, the electronic device can also include a control device, which is communicated with the first pressure detection element 310 and the electrodeformable element respectively, and the control device controls the power-on state of the electrodeformable element according to the pressure value detected by the first pressure detection element 310; of course, the deformation element 320a can also be a temperature-induced deformation element, and the temperature-induced deformation element can be a temperature-sensitive sheet, and the temperature-induced deformation element can be connected to a heating wire, and the temperature-induced deformation element is heated by using whether the heating wire is energized, and the deformation degree of the temperature-induced deformation element is changed by changing the heating temperature.

[0041] In this embodiment, the deformation element 320a is used as the first driving member 320. The structure of the first driving member 320 is simpler, and there is no need to control parameters such as its position and speed, and the control process is also simpler.

[0042] In a further embodiment, the deformation element 320a is a deformation bar, the end of the deformation bar is slidably connected to the first device body 110, and the middle area of ​​the deformation bar is connected to the first sliding member 400. Optionally, the end of the deformation bar can be slidably connected to the first device body 110 through a matching slide rail and a slider, or can be slidably connected in other ways; the middle area of ​​the deformation bar can be fixedly connected to the first sliding member 400 through a first connecting glue 610.

[0043] When the deformation bar is in a deformed state, the middle area of ​​the deformation bar drives the first sliding member 400 to slide along the first direction A relative to the first device body 110, and the end of the deformation bar slides along the second direction B relative to the first device body 110. Specifically, when the middle area of ​​the deformation bar slides, the two ends of the deformation bar move away from each other in opposite directions, and the two ends of the deformation bar slide respectively relative to the first device body 110.

[0044] The first direction A intersects with the second direction B, and the first direction A and the second direction B are respectively parallel to the plane where the first portion 210 of the display screen 200 is located. Optionally, the first direction A may be the sliding direction of the first sliding member 400, that is, the extension direction of the first slide groove 101, and the second direction B may be perpendicular to the first direction A. Further, optionally, the first direction A may be the width direction of the first device body 110, and the second direction B may be the length direction of the first device body 110.

[0045] With this embodiment, when the deformation bar is deformed, the deformation degree of the middle area thereof is relatively large, so the middle area thereof is connected to the first sliding member 400, which can drive the first sliding member 400 and the first part 210 of the display screen 200 to slide a relatively large distance, effectively preventing the folded part of the display screen 200 from being violently hit; moreover, the first device body 110 provides sliding support for both ends of the deformation bar respectively, which is more conducive to the stable deformation of the middle area of ​​the deformation bar, thereby driving the first sliding member 400 to slide more stably.

[0046] Of course, in other embodiments, the first end of the deformation bar is connected to the first device body 110, and the second end of the deformation bar is connected to the first sliding member 400. When the deformation bar is deformed, the first end of the deformation bar and the second end of the deformation bar approach each other, thereby driving the first sliding member 400 to slide relative to the first sliding groove 101.

[0047] In an alternative embodiment, reference Fig. 9 and Fig.12 As shown, the first adjustment mechanism 300 further includes a second sliding member 500, the end of the deformation bar is connected to the second sliding member 500, the first device body 110 is provided with a second slide groove 102, the second slide groove 102 extends along the second direction B, and the second sliding member 500 is slidably matched with the second slide groove 102. Optionally, the end of the deformation bar can be connected to the second sliding member 500 by welding, bonding, etc., and further optionally, the end of the deformation bar is connected to the second sliding member 500 by a second connecting glue 620.

[0048] When the deformation element 320a is not deformed, refer to Fig. 9As shown, the second sliding member 500 is located at the first end of the second slide groove 102; when the deformation element 320a is deformed, the second sliding member 500 slides along the second slide groove 102 until the second sliding member 500 is located at the second end of the second slide groove 102, as shown in FIG. Fig.12 shown.

[0049] Optionally, the second sliding member 500 can be a slider, a sliding bar or other structures, and the embodiment of the present application does not limit the structure of the second sliding member 500; the second slide groove 102 can also be a square groove or other structures, and the embodiment of the present application does not limit the structure of the second slide groove 102, and the surface of the second sliding member 500 cooperates with the groove wall surface of the second slide groove 102.

[0050] With this embodiment, the end of the deformation strip is slidably matched with the first device body 110 through the second sliding member 500 and the second sliding groove 102. It is only necessary to add the second sliding member 500 and open the second sliding groove 102. There is no need to separately set up structures such as sliding rails and sliders. The sliding matching structure is simple, which is conducive to simplifying the structure of the electronic device.

[0051] In this embodiment, the first device body 110 is provided with at least two second slide grooves 102 , and both ends of the deformation strip are connected to the second sliding member 500 , and the second sliding member 500 corresponds to the second slide groove 102 one by one and slides in cooperation.

[0052] In yet another alternative, reference Fig.15 and Fig.16 As shown, the first driving member 320 is a driving source 320b, and the driving source 320b is arranged on the first device body 110. Optionally, the driving source 320b can be a driving member that can provide rotational power, such as a motor, a pneumatic motor, etc., and the housing of the driving source 320b can be fixedly connected with the first device body 110 by welding, bonding, etc. The first adjusting mechanism 300 also includes a transmission assembly 330, and the transmission assembly 330 is used to transmit the power of the driving source 320b to the first sliding member 400, and the output shaft of the driving source 320b is connected to the first sliding member 400 through the transmission assembly 330. In this way, when the driving source 320b is working, the output shaft of the driving source 320b transmits power to the first sliding member 400 through the transmission assembly 330, thereby driving the first sliding member 400 to slide.

[0053] When the electronic device is in the folded state and the pressure value detected by the first pressure detection element 310 reaches the pressure threshold, it means that the first part 210 of the display screen 200 is subjected to a large force, the driving source 320b is in the working state, and the driving source 320b drives the first sliding member 400 through the transmission assembly 330 to drive the first part 210 of the display screen 200 to slide relative to the first device body 110. When the pressure value detected by the first pressure detection element 310 is less than the pressure threshold, it means that the first part 210 of the display screen 200 is subjected to a small force or no force, the driving source 320b is in the non-working state, the first sliding member 400 has no driving force, and the position of the first sliding member 400 relative to the first device body 110 is fixed.

[0054] In this embodiment, the driving source 320b is used as the first driving member 320. When the force on the display screen 200 reaches the pressure threshold, the driving source 320b can promptly drive the first sliding member 400 to slide, which is beneficial for the first part 210 of the display screen 200 to slide in time, so as to effectively avoid the folded part of the display screen 200 from being hit.

[0055] Optionally, the electronic device may further include a control device, which is communicatively connected to the first pressure detection element 310 and the driving source 320 b respectively, and controls the working state of the driving source 320 b according to the pressure value detected by the first pressure detection element 310 .

[0056] In a further embodiment, the transmission assembly 330 includes a gear 331, which is sleeved on the outside of the output shaft of the driving source 320b. Optionally, the gear 331 and the output shaft of the driving source 320b can be connected by welding, bonding, etc. The output shaft of the driving source 320b intersects with the sliding direction of the first sliding member 400. Optionally, the output shaft of the driving source 320b is perpendicular to the sliding direction of the first sliding member 400. The first sliding member 400 is provided with a plurality of meshing teeth 410 at intervals along its own sliding direction, and the meshing teeth 410 mesh with the gear 331.

[0057] In this way, when the driving source 320b is working, the output shaft of the driving source 320b drives the gear 331 to rotate, and relying on the meshing structure between the gear 331 and the meshing tooth 410, the gear 331 drives the first sliding member 400 to slide; when the driving source 320b is not working, the output shaft of the driving source 320b stops rotating, and the meshing structure between the gear 331 and the meshing tooth 410 limits the first sliding member 400, so that the position of the first sliding member 400 relative to the first device body 110 is fixed.

[0058] With this embodiment, the transmission mode of tooth meshing has the advantages of a wide adaptability range, high transmission efficiency, long service life, smooth transmission, and high reliability. The rotational power of the driving source 320b is converted into the moving power of the first sliding member 400 by means of tooth meshing, which is conducive to stably driving the first sliding member 400 to slide. Of course, in other embodiments, the transmission assembly 330 may also adopt other structures besides the gear 331 and the meshing teeth 410 to realize power transmission. Optionally, the output shaft of the driving source 320b may be parallel to the sliding direction of the first sliding member 400, and a sleeve is provided on the outside of the output shaft of the driving source 320b, and the sleeve is provided with a spiral groove. The first sliding member 400 is provided with a columnar protrusion, which extends into the spiral groove, and the columnar protrusion slides in cooperation with the spiral groove.

[0059] In an alternative embodiment, reference Figure 4 As shown, the first pressure detection element 310 is disposed between the first sliding member 400 and the display screen 200.

[0061] Of course, in other embodiments, the first pressure detecting element 310 may not be located between the first sliding member 400 and the display screen 200 , and the first pressure detecting element 310 may be directly disposed at other positions of the display screen 200 .

[0062] In addition to the electromagnetic component, the deformation element 320a and the driving source 320b, the first driving member 320 can also be other driving structures that can drive the first sliding member 400 to slide. The embodiment of the present application does not limit the specific structure of the first driving member 320.

[0063] In an optional embodiment, the first adjustment mechanism 300 includes a first driving member 320 , and the first driving member 320 is located on one side of the first sliding member 400 .

[0064] In another embodiment, the first adjustment mechanism 300 includes a plurality of first driving members 320 arranged at intervals. Fig.15As shown, the first driving member 320 may be the driving source 320b mentioned above, or may be the first electromagnetic member 321 and the second electromagnetic member 322 mentioned above. The two first driving members 320 are respectively located on opposite sides of the first sliding member 400 along the third direction. The third direction intersects with the sliding direction of the first sliding member 400, and the third direction is parallel to the plane where the first part 210 of the display screen 200 is located. Optionally, the third direction may be perpendicular to the sliding direction of the first sliding member 400, that is, the third direction is the second direction B mentioned above; of course, the third direction may also intersect with the sliding direction of the first sliding member 400 but not perpendicular.

[0065] According to the present embodiment, a plurality of first driving members 320 are provided, and the plurality of first driving members 320 generate driving forces at different positions, so as to drive different positions of the first sliding member 400 to slide relative to the first sliding groove 101, which is more conducive to the stable sliding of the first sliding member 400 relative to the first sliding groove 101 when the first part 210 of the display screen 200 is subjected to greater force.

[0066] In an optional embodiment, the second part 220 of the display screen 200 is slidably connected to the second device body 120. Optionally, the second part 220 of the display screen 200 and the second device body 120 can be slidably connected through a matching slide rail and a slider, or the second device body 120 can be provided with a third slide groove, the second part 220 of the display screen 200 is connected to the third slider, and the third slider is slidably matched with the third slide groove, so as to achieve the sliding connection between the second part 220 of the display screen 200 and the second device body 120. In addition, the electronic device further includes a second adjustment mechanism 700, which can automatically adjust the motion state of the second part 220 of the display screen 200. The second adjustment mechanism 700 can have the same structure as the first adjustment structure.

[0067] Specifically, the second adjustment mechanism 700 includes a second pressure detection element 710 and a second driving member 720. The second pressure detection element 710 may be, but is not limited to, a pressure sensor. The second pressure detection element 710 is connected to the second portion 220 of the display screen 200 to detect the pressure value of the display screen 200. The second driving member 720 is connected to the second portion 220 of the display screen 200. Optionally, the second pressure detection element 710 may be directly connected to the second portion 220 of the display screen 200 by welding, bonding, etc., or may be indirectly connected by connecting other components. Further, optionally, the second pressure detection element 710 is connected to the second portion 220 of the display screen 200 by a third connecting adhesive.

[0068] When the electronic device is in a folded state and the pressure value detected by the second pressure detection element 710 reaches the pressure threshold, it means that the second part 220 of the display screen 200 is subjected to a large pressure value, that is, the display screen 200 is subjected to a large pressure value. At this time, the second driving member 720 drives the second part 220 of the display screen 200 to slide relative to the second device body 120 in a direction away from the first axis, so as to avoid the folded part of the display screen 200 being violently hit, thereby causing the display screen 200 to crack and bend, and to avoid damage to the display screen 200, so as to avoid affecting the service life of the electronic device. Optionally, the sliding direction of the second part 220 of the display screen 200 is parallel to the sliding direction of the first part 210 of the display screen 200.

[0069] When the pressure value detected by the second pressure detection element 710 does not reach the pressure threshold, it means that the second portion 220 of the display screen 200 is not subjected to force or the pressure value is small, and the second driving member 720 is not working at this time, and the second portion 220 of the display screen 200 is fixed relative to the second device body 120. It should be noted that the user can set the pressure threshold as needed.

[0070] In this embodiment, the structure of the first adjustment mechanism 300 is the same as that of the second adjustment mechanism 700, that is, the specific types and settings of the first pressure detection element 310 and the second pressure detection element 710 are the same, respectively, and the first driving member 320 and the second driving member 720 can both include the first electromagnetic member 321, the second electromagnetic member 322, the third electromagnetic member 323 and the fourth electromagnetic member 324 mentioned above, and can also include the deformation element 320a mentioned above, and can also include the driving source 320b mentioned above. When the electronic device falls, that is, the display screen 200 is subjected to a large pressure, the first adjustment mechanism 300 adjusts the motion state of the first part 210 of the display screen 200, and at the same time, the second adjustment mechanism 700 adjusts the motion state of the second part 220 of the display screen 200.
