Description

Technical Field

[0001] This application relates to the field of electronic technology, and more particularly to an electronic device and a control method thereof. Background Technology

[0002] With the development of electronic technology, electronic devices such as smartphones are becoming increasingly intelligent, and their functions are becoming more and more numerous. The screen display effect of electronic devices is receiving more and more attention. However, the size of mobile phones limits the expansion of screen size. Therefore, utilizing the bendable and foldable characteristics of flexible screens to expand the display area of ​​electronic devices has become a new development direction.

[0003] Currently, electronic devices feature a flexible screen whose state can be changed through a relatively sliding housing. This flexible screen can be partially located outside and partially inside the electronic device. The size of the portion of the flexible screen outside the device can be adjusted according to user needs, serving as a display area to provide images. However, when subjected to external forces such as impacts, pressure, or pushing / pulling forces, the relatively sliding housing is prone to changing its state, potentially damaging the flexible screen and internal components, resulting in poor reliability of the electronic device. Summary of the Invention

[0011] This application also provides a control method applied to an electronic device, the electronic device including the electronic device described above, the control method including:

[0015] This application provides an electronic device and a control method. The electronic device includes: a first housing, a second housing, a driving member, a traction member, and a limiting component. The second housing is connected to the first housing and can slide relative to the first housing. The driving member is fixedly disposed on the first housing.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] This application provides an electronic device, which includes, but is not limited to, mobile terminals such as mobile phones and tablets, or other portable electronic devices. For ease of understanding, the following description uses a mobile phone as an example.

[0035] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the flexible display screen of the electronic device provided in the embodiment of this application in a first state. Figure 2 This is a schematic diagram of the flexible display screen of the electronic device provided in the embodiment of this application in a second state.

[0036] The electronic device 20 in this embodiment includes a first housing 220, a second housing 240, and a flexible display module 260. The second housing 240 is slidable relative to the first housing 220, and the display area of ​​the flexible display module 260 can be changed according to the relative sliding of the first housing 220 and the second housing 240. The second housing 240 and the first housing 220 can form a receiving space. The flexible display module 260 can be installed on the first housing 220 and the second housing 240, wherein the flexible display module 260 is at least partially disposed outside the receiving space. The flexible display module is at least partially hidden within the receiving space. During the movement of the second housing 240 relative to the first housing 220, the flexible display module 260 can be moved to switch between a first state and a second state. When the first housing 220 and the second housing 240 are relatively far apart, the flexible display module 260 can be unfolded to put the flexible display module 260 into the second state (e.g., ...). Figure 2 As shown), this allows more of the flexible display module 260's display portion to be exposed outside the receiving space. When the first housing 220 and the second housing 240 are relatively close, they can cause the flexible display module 260 to retract, so that the flexible display module 260 is in a second state (as shown). Figure 1 As shown in the figure, this allows more of the flexible display module 260 to be hidden within the housing space.

[0037] However, in related technologies, when the flexible display module 260 is in a first state, a second state, or an intermediate state between the first and second states, the electronic device 20 is subjected to external forces such as impact, compression, or pushing / pulling forces. The relative positions of the first housing 220 and the second housing 240 are easily altered unexpectedly by these external forces, potentially damaging the flexible display module 260 and the internal components of the electronic device 20. Therefore, this application provides an electronic device with a limiting component, which can restrict the positions of the first and second housings, improving the stability of the electronic device. Please continue reading. Figure 3 , Figure 3 A partial structural schematic diagram of the electronic device provided in the embodiments of this application.

[0038] The electronic device 20 includes a first housing 220, a second housing 240, a driving member 211, a traction member 212, and a limiting component 230. The second housing 240 is connected to the first housing 220 and can slide relative to the first housing 220. The driving member 211 is fixedly disposed on the first housing 220. The traction member 212 is connected to the driving member 211. The limiting component 230 is movably connected to the traction member 212. The driving member 211 drives the limiting component 230 to move through the traction member 212, so that the limiting component 230 limits the first housing 220 and the second housing 240 when the second housing 240 slides relative to the first housing 220 to a preset position.

[0039] It should be noted that during the relative sliding process of the first housing 220 and the second housing 240, the first housing 220 can be used as a fixed end and the second housing 240 can be used as a moving end. The driving member 211 is fixedly disposed on the first housing 220, which is the fixed end. In some embodiments, the second housing can be used as a fixed end and the first housing can be used as a moving end. In this case, the driving member can be fixedly disposed on the second housing.

[0040] The driving component 211 can change the position of the traction component 212. For example, the traction component 212 can deform itself to change its position, or the traction component can be pulled directly to change its position. When the position of the traction component 212 changes, the traction component 212 pulls the limiting component 230 connected to the traction component. The position of the limiting component 230 relative to the first housing 220 and the second housing 240 changes to limit the position of the first housing 220 and the second housing 240.

[0041] For details, please refer to Figure 3 and Figure 4 , Figure 4This is a schematic diagram of the structure of the second housing provided in an embodiment of this application. The second housing 240 is provided with at least two limiting grooves, which are arranged along the sliding direction of the second housing. The limiting grooves are used to cooperate with a limiting component so that the limiting component engages with one of the at least two limiting grooves when the second housing slides relative to the first housing to a preset position. For example, the second housing 240 is provided with two limiting grooves, a first limiting groove 241 and a second limiting groove 242, which are arranged along the sliding direction of the second housing 240 and spaced apart. The limiting component 230 engages with the first limiting groove 241 when the second housing slides relative to the first housing to a first preset position. The first preset position can be the flexible display module being in a second state (e.g., ...). Figure 2 The position shown is such that the relative position between the first housing 220 and the second housing 240 is locked in the first state. The limiting component 230 engages with the second limiting groove 242 when the second housing slides relative to the first housing to a second preset position. The second preset position can be when the flexible display module is in the first state (e.g., as shown). Figure 1 The position shown is such that the relative position between the first housing 220 and the second housing 240 is locked in the second state. The first preset position can also be understood as the position where the flexible display module is in the unfolded state, and the second preset position can also be understood as the position where the flexible display module is in the retracted state.

[0042] In some embodiments, a third limiting groove may be provided between the first limiting groove 241 and the second limiting groove 242. When the limiting component 230 slides the second housing 240 relative to the first housing 220 to the third preset position, it engages with the third limiting groove. The third preset position may be the position of the flexible display module in the intermediate state between the first state and the second state. The third preset position may also be understood as the position of the flexible display module in the intermediate state between the unfolded state and the retracted state. Of course, other limiting grooves can also be provided between the first limiting groove 241 and the second limiting groove 242. When the limiting component 230 slides the second housing 240 relative to the first housing 220 to other preset positions, it engages with the corresponding other limiting grooves. The other preset positions can be the positions of the flexible display module in the intermediate state between the first state and the second state. The other preset positions can also be understood as the positions of the flexible display module in the intermediate state between the unfolded state and the retracted state. The other preset positions can be different from the third preset position. The other preset positions can include one or more preset positions, which can meet the user's needs for different display sizes of the flexible display module, and at the same time improve the reliability of the electronic device when meeting the user's needs for different display sizes of the flexible display module.

[0043] Understandably, the driving component 211 and the traction component 212 can drive the limiting component 230 to switch between an unlocked state and a locked state. When the limiting component 230 is in the locked state, a portion of the limiting component 230 can engage with the limiting groove provided in the second housing to restrict relative sliding between the first housing 220 and the second housing 240, thereby locking the relative position between the first housing and the second housing at the corresponding position. When the limiting component is in the unlocked state, the portion of the limiting component 230 that engages with the limiting groove can move out of the limiting groove, and relative sliding can occur between the first housing 220 and the second housing 240.

[0044] Please continue reading. Figures 3 to 9 , Figure 5 for Figure 3 The diagram shows the structure of the limiting component, the driving component, and the traction component. Figure 6 for Figure 5 A magnified view of part A shown. Figure 7 for Figure 6 The diagram shows a split structure. Figure 8 for Figure 6 A schematic diagram of the structure shown from another perspective. Figure 9 for Figure 8 The diagram shows a cross-sectional view of the structure along the PP direction.

[0045] The limiting component 230 includes a limiting member 231 and a first base 232. The first base 232 is fixedly disposed on the first housing 220. The first housing 220 may include a first frame 221 disposed perpendicular to the sliding direction. The first base 232 may be fixedly disposed on the first frame 221. The first base 232 may be provided with a fixing part 2321 for fixing to the first frame 221. The first frame 221 may be provided with a mating part for fixing to the first base 232. The fixing part and the mating part are connected by the fixing member to realize the fixed connection between the first base 232 and the first frame 221. The fixing member may be a screw, threaded rod, buckle, or other fixing member.

[0046] The first base 232 is provided with a receiving space 2322 and a first through hole 2323 and a second through hole 2324 communicating with the receiving space 2322. The limiting member 231 passes through the first through hole 2323 and is at least partially located in the receiving space 2322. The traction member 212 passes through the second through hole 2324 and is connected to the limiting member 231 in the receiving space 2322. To improve the stability of the traction member 212, the first base 232 can be provided with two second through holes 2324, which are arranged opposite each other. The traction member 212 can pass through the two second through holes 2324 respectively and connect with the limiting member 231 within the receiving space 2322. Compared with the scheme of guiding the traction member into the receiving space and connecting with the limiting member through only one second through hole, guiding the traction member into the receiving space and connecting with the limiting member through two oppositely arranged second through holes can increase the volume of the traction member entering the receiving space and the contact area between the traction member and the limiting member. This can improve the stability of the traction member drive during the process of the traction member pulling the limiting member. It avoids the situation where the movement of the limiting member is unstable due to the small contact area between the traction member and the limiting member during the pulling process, thus affecting the limiting effect of the limiting component.

[0047] The first base 232 is also provided with a third through hole 2325, which is disposed opposite to the first through hole 2323. The limiting member 231 may include a limiting block 2311 passing through the first through hole 2323 and a limiting rod 2312 fixedly connected to the limiting block 2311 and passing through the third through hole 2325. The limiting rod 2312 is sleeved with a first elastic member 213, which is disposed in the accommodating space 2322. The limiting rod 2312 may include a connecting part 23121 near the limiting block 2311 and for connecting with the limiting block 2311, and a passing part 23122. The first elastic member 213 is sleeved in the passing part 23122. One end of the first elastic member 213 abuts against the connecting part 23121 of the limiting rod 2312 near the limiting block 2311, and the other end of the first elastic member 213 abuts against the first base 232. The connecting part 23121 of the limiting rod 2312 is provided with a first traction groove 23123, and at least a portion of the traction member 212 is provided in the first traction groove 23123.

[0048] When the driving member 211 drives the limiting member 231 to move through the traction member 212, the traction member 212 pulls the connecting part 23121 in a direction perpendicular to the sliding direction of the second housing 240, thereby pulling the limiting rod 2312. The limiting block 2311 is fixedly connected to the limiting rod 2312, so the limiting block 2311 can be pulled. Due to the restriction of the first base 232, the connecting part 23121 of the limiting rod 2312 and the inner wall of the first base 232 jointly squeeze the first elastic member 213, and the first elastic member 213 undergoes elastic deformation. When the second housing 240 slides to the preset position relative to the first housing 220, the first elastic member 213 can give the limiting block 2311 an elastic restoring force, so that the limiting block 2311 is engaged with the limiting groove to realize the limiting function. In some embodiments, when the second housing 240 slides relative to the first housing 220 to a preset position, the driving member 211 can drive the traction member 212 to move, and give the traction member 212 a driving force and an elastic restoring force to act on the limiting block 2311, so that the limiting block 2311 is engaged with the limiting groove to achieve the limiting function.

[0049] In some embodiments, the traction member 212 can be electrically connected to the driving member 211, and the driving member 211 can cause the traction member 212 to deform. The traction member 212 can be a shape memory wire made of shape memory metal material. When the shape memory wire is energized by the driving member 211, it deforms, thereby pulling the limiting rod 2312 connected to it, putting the limiting component 230 in an unlocked state. When the power is de-energized by the driving member 211, the shape memory wire returns to its initial state and can push the limiting rod 2312 connected to the traction member 212, putting the limiting component 230 in a locked state. By energizing and de-energizing the shape memory wire by the driving member 211, and controlling the timing of energizing and de-energizing, the limiting component 230 can switch between an unlocked state and a locked state. This embodiment achieves the limiting function of the first and second housings by energizing and de-energizing the shape memory metal wire. The logic is simple, and it can limit the first and second housings to different relative positions. Shape memory metal has a large energy density, driving strain, and driving stress, and the driving voltage is low, making it relatively easy to implement. The overall structure of the driving component, traction component, and limiting component is small in size and weight, without occupying much space inside the electronic device. In addition, a large tensile force can be generated on the limiting component using only a single shape memory metal wire, which can reduce the driving force of the driving component on the shape memory metal wire.

[0050] The electronic device provided in this application embodiment drives the movement of the limiting component through the driving component and the traction component. When the second housing slides relative to the first housing to a preset position, it limits the second housing. When the electronic device is subjected to external forces such as impact force, squeezing force, pushing force, etc., it can limit the relative position of the first housing and the second housing, avoid the relative movement of the first housing and the second housing, prevent the flexible screen and the internal components of the electronic device from being damaged, effectively protect the electronic device, and improve the reliability of the electronic device.

[0051] To prevent damage to the traction component due to jamming between the limiting component and the limiting groove, taking a shape memory wire as an example, if unpredictable factors cause high friction between the limiting component and the limiting groove, and the tension of the shape memory wire on the limiting component is less than the friction between the limiting component and the limiting groove, then applying current to the shape memory wire can easily cause irreversible deformation, leading to its failure. To prevent damage to the traction component, the limiting assembly can include a protective mechanism to protect the shape memory wire. For details, please refer to [link to relevant documentation]. Figures 10 to 14 , Figure 10 This is a schematic diagram of another part of the structure of the electronic device provided in the embodiments of this application. Figure 11 for Figure 10 The diagram shows the structure of the limiting component, the driving component, and the traction component. Figure 12 for Figure 11 A magnified view of part B shown. Figure 13 for Figure 12 The diagram shows a split structure. Figure 14 for Figure 12 A schematic diagram of the structure shown from another perspective. Figure 15 for Figure 14 The diagram shows a cross-sectional view of the structure along the QQ direction.

[0052] The electronic device 20 includes a first housing 220, a second housing 240, a driving member 211, a traction member 212, and a limiting component 230. The second housing 240 is connected to the first housing 220 and can slide relative to the first housing 220. The driving member 211 is fixedly disposed on the first housing 220. The traction member 212 is connected to the driving member 211. The limiting component 230 is movably connected to the traction member 212. The driving member 211 drives the limiting component 230 to move through the traction member 212, so that the limiting component 230 limits the first housing 220 and the second housing 240 when the second housing 240 slides relative to the first housing 220 to a preset position.

[0053] It should be noted that during the relative sliding process of the first housing 220 and the second housing 240, the first housing 220 can be used as a fixed end and the second housing 240 can be used as a moving end. The driving member 211 is fixedly disposed on the first housing 220, which is the fixed end. In some embodiments, the second housing 240 can be used as a fixed end and the first housing 220 can be used as the moving end. In this case, the driving member 211 can be fixedly disposed on the second housing 240.

[0054] The driving component 211 can change the position of the traction component 212. For example, the traction component 212 can deform itself to change its position, or the traction component can be pulled directly to change its position. When the position of the traction component 212 changes, the traction component 212 pulls the limiting component 230 connected to the traction component. The position of the limiting component 230 relative to the first housing 220 and the second housing 240 changes to limit the position of the first housing 220 and the second housing 240.

[0055] The limiting component 230 may include a limiting member 231 and a protection mechanism 233 connected together. The traction member 212 is connected to the driving member 211 and the protection mechanism 233 respectively. The driving member 211 drives the protection mechanism 233 to move through the traction member 212, so as to drive the limiting member 231 connected to the protection mechanism 233 to move.

[0056] Specifically, the protection mechanism 233 may include a second base 2331 and a protective member 2332. The second base 2331 is provided with a receiving groove 23311. The groove wall of the receiving groove 23311 is provided with a fourth through hole 2333. The protective member 2332 passes through the fourth through hole 2333 and is at least partially located in the receiving groove 23311. The portion of the protective member 2332 located in the receiving groove 23311 is fitted with a second elastic member 214. One end of the second elastic member 214 abuts against the end 23321 of the protective member 2332 near the limiting member 231, and the other end of the second elastic member 214 abuts against the groove wall 23312 provided with the fourth through hole 2333.

[0057] The traction member 212 can be connected to the protective member 2332. For example, the protective member 2332 is provided with a second traction groove 2334 at one end near the limiting member 231, and a clearance opening 2335 is also provided on the groove wall 23312 on one side of the opening of the receiving groove 23311. The traction member 212 passes through the clearance opening 2335 and at least part of it is provided in the second traction groove 2334. To improve the stability of the traction member 212, two clearance openings 2335 can be provided at the free end of the groove wall 23312. The position and size of the two clearance openings 2335 can be set according to the position and size of the traction member 212. The traction member 212 can be respectively inserted through the two clearance openings 2335 and connected to the protective member 2332 in the receiving groove 23311 to improve the stability when the driving member 211 drives the traction member 212. Compared with the scheme of guiding the traction member into the receiving groove and connecting with the limiting member through only one clearance opening, guiding the traction member into the receiving groove and connecting with the limiting member through two relatively set clearance openings can increase the volume of the traction member entering the receiving groove and the contact area between the traction member and the limiting member. During the process of the traction member pulling the limiting member, the driving stability of the traction member can be improved. This avoids the situation where the movement of the limiting member is unstable due to the small contact area between the traction member and the limiting member during the pulling process, which would affect the limiting effect of the limiting component.

[0058] The limiting component 230 also includes a third base 234, which is fixedly disposed on the first housing 220. The first housing 220 may include a first frame 221 that is perpendicular to the sliding direction. The third base 234 may be fixedly disposed on the first frame 221. The third base 234 may be provided with a fixing part 2341 for fixing to the first frame 221. The first frame 221 may be provided with a mating part for fixing to the third base 234. The fixing part 2341 and the mating part are connected by a fastener to achieve a fixed connection between the third base 234 and the first frame 221. The fastener may be a screw, threaded rod, buckle, or other fastener.

[0059] The third base 234 may be provided with a receiving space 2342 and a fifth through hole 2343 and a sixth through hole 2344 communicating with the receiving space 2342. The limiting member 231 passes through the fifth through hole 2343 and the sixth through hole 2344 and is at least partially located in the receiving space 2342. The portion of the limiting member 231 located in the receiving space 2342 is fitted with a third elastic member 215.

[0060] The limiting member 231 includes a first limiting portion 2313 passing through the fifth through hole 2343 and a second limiting portion 2314 passing through the sixth through hole 2344. The size of the first limiting portion 2313 is larger than the size of the second limiting portion 2314. One end of the third elastic member 215 abuts against the first limiting portion 2313, and the other end of the third elastic member 215 abuts against the third base 234.

[0061] When the driving member 211 drives the protective member 2332 to move through the traction member 212, the traction member 212 pulls the protective member 2332 in a direction perpendicular to the sliding direction of the second housing 240, and then pulls the second base 2331. Since the limiting member 231 is fixedly connected to the second base 2331, the second base 2331 drives the limiting member 231 to move in a direction perpendicular to the sliding direction of the second housing 240. Due to the restriction of the third base 234, the first limiting part 2313 of the limiting member 231 and the inner wall of the third base 234 jointly squeeze the third elastic member 215, and the third elastic member 215 undergoes elastic deformation. When the second housing 240 slides to the preset position relative to the first housing 220, the second elastic member 214 can give the limiting member 231 an elastic restoring force, so that the limiting member is engaged with the limiting groove to realize the limiting function. In some embodiments, when the second housing 240 slides to a preset position relative to the first housing 220, the driving member 211 can drive the traction member 212 to move, and give the traction member 212 a driving force and an elastic restoring force to act on the limiting member 231, so that the limiting member 231 is engaged with the limiting groove to achieve the limiting function.

[0062] Specifically, when the traction member 212 is a memory metal wire, the memory metal wire is energized by the driving member 211, causing it to deform and contract, generating a contraction force that acts on the second elastic member 214. The second elastic member 214 then applies this force to the second base 2331. The second base 2331 and the limiting member 231 can be connected as a whole by a fixing member. Therefore, when the memory metal wire deforms and contracts, it drives the limiting member 231 to move in the direction of the wire's contraction, thus unlocking the limiting assembly. After the power is de-energized, the wire returns to its original length, and under the elastic restoring force of the third elastic member 215, the limiting member moves towards the limiting groove, thus locking the limiting assembly. The second elastic member 214 and the third elastic member 215 can be springs. Assuming the elastic coefficient of the second elastic member 214 is K... B The elastic modulus of the third elastic element 215 is K. F The shape memory wire can move towards the driving member 211 with a displacement of Δx2 when energized, and the limiting member 231 can move towards the driving member 211 with a displacement of Δx1. They have the following relationship:

[0063]

[0064] Therefore, the movable displacement Δx1 of the limiting member 231 is less than the shrinkage amount Δx2 of the memory wire. To satisfy the travel distance Δx1 of the limiting member 231, the closer the values ​​of Δx1 and Δx2 are, the smaller the loss caused by the shrinkage of the memory wire, and the loss amount = Δx2 - Δx1. Therefore, given the limited space in the whole machine, the elastic coefficient K of the second elastic member 214 is... BThe elastic coefficient K is much greater than that of the third elastic element 215. F At that time, the shrinkage loss of the shape memory wire can be close to 0.

[0065] When the friction between the limiting component and the limiting groove is large due to some uncertain factors, the pulling force of the memory metal wire on the limiting component is less than the friction between the limiting component and the limiting groove, and the limiting component and the limiting groove are stuck, even if the memory metal wire is energized, it will only compress the second elastic component. The second elastic component provides the displacement of the memory metal wire deformation, which plays a role in protecting the memory metal wire.

[0066] The electronic device provided in this application embodiment has a protective structure, which can prevent damage to the traction component due to jamming between the limiting component and the limiting groove, thereby further improving the reliability of the electronic device.

[0067] To further improve the reliability of electronic devices, at least two sets of limit components can be installed within the device. Please refer to [further details]. Figure 3 The limiting components may include a first limiting component 230 and a second limiting component 250. The first housing 220 includes a first frame 221 perpendicular to the sliding direction of the second housing 240. The first limiting component 230, the second limiting component 250, and a driving member 211 are disposed on the first frame 221. The driving member 211 is disposed between the first limiting component 230 and the second limiting component 250. The driving member 211 is movably connected to the first limiting component 230 via a traction member 212, and is also movably connected to the second limiting component 250 via a traction member 216. The structures of the first limiting component 230 and the second limiting component 250 are similar to those of the limiting component 230 described above, and will not be repeated here.

[0068] It is understood that the second housing 240 may be provided with a limiting groove corresponding to the second limiting component 250, so that the second limiting component 250 can perform the limiting function on the first housing 220 and the second housing 240.

[0069] It should be noted that the structure of the electronic device 20 shown in the above embodiments is merely exemplary, and the positions and structures of the first housing, second housing, driving member, traction member, and limiting component of the electronic device can be adaptively adjusted according to actual needs.

[0070] This application also provides a control method applied to an electronic device, which can be the electronic device described above. The control method may include:

[0071] When an unlock signal is received, the limiting component is driven to move by the driving component and the traction component, so that the limiting component is in the unlocked state, and the second housing can slide relative to the first housing;

[0072] Drive the second housing to slide relative to the first housing;

[0073] When the second housing is detected to have slid to a preset position relative to the first housing, the limiting component is driven to move by the driving member and the traction member, so that the limiting component is in a locked state, and the limiting component limits the first housing and the second housing.

[0074] In a specific application scenario, when the flexible display module is in the retracted state, the memory metal wire can be de-energized, and the limiting component is in a locked state. When the flexible display module needs to be unfolded, an unlocking signal is generated. If the unlocking signal is received, the memory metal wire is energized through the driving component, causing the limiting component to be unlocked. The second housing can slide relative to the first housing, thereby driving the flexible display module to unfold. When the second housing slides relative to the first housing to a preset position, which can be the preset position as described above, the memory metal wire is de-energized through the driving component, causing the memory metal wire to return to its initial position. Due to the elastic restoring force of the first elastic element, the limiting component can engage with the limiting groove corresponding to the preset position, thereby locking the first housing and the second housing in the preset position.

[0075] In a specific application scenario, when the flexible display module is in the retracted state, the memory metal wire can be in a de-energized state, and the limiting component is in a locked state. When the flexible display module needs to be in the unfolded state, an unlocking signal is generated. If the unlocking signal is received, the memory metal wire is energized through the driving component, so that the limiting component is in the unlocked state. The second shell can slide relative to the first shell, thereby driving the flexible display module to unfold. By calculating in advance the time for the second shell to slide to the preset position relative to the first shell, and de-energizing the memory metal wire before the second shell slides to the preset position, the response time of the limiting component switching to the locked state can be shortened.

[0076] This application provides a control method applied to the aforementioned electronic device. Upon receiving an unlock signal, the driving component and traction component drive the limiting component to move, thereby placing the limiting component in an unlocked state, allowing the second housing to slide relative to the first housing. The method then drives the second housing to slide relative to the first housing. When the second housing is detected to have slid to a preset position relative to the first housing, the driving component and traction component drive the limiting component to move, thereby placing the limiting component in a locked state. The limiting component limits the movement of both the first and second housings. When the electronic device is subjected to external forces such as impact, compression, or push-pull forces, this method restricts the relative positions of the first and second housings, preventing relative movement and protecting the flexible screen and internal components from damage. This effectively safeguards the electronic device and improves its reliability.

[0077] The electronic device control method provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
