Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a foldable electronic device. Background Art

[0002] As flexible screen technology matures, the display mode of electronic devices has undergone tremendous changes. One of these changes 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 seek out most.

[0003] Currently, foldable electronic devices, such as those that fold into two layers, typically include a first shell and a second shell that can rotate relative to each other. The first shell and the second shell can move toward each other to a folded state, closing the electronic device; alternatively, the first shell and the second shell can move away from each other to an unfolded state, unfolding the electronic device. To ensure that the first and second shells can remain in the folded state for a long time, the first shell is typically provided with a button and a retractable snap-on structure, while the second shell is provided with a snap-on slot. Specifically, the first shell may have a side cover, and the button may be provided on the side cover. When the first and second shells are folded, the side cover typically remains flush with the second shell, and the snap-on structure can extend from the outside of the first shell and into the snap-on slot, locking the first and second shells together and maintaining the folded state. When the first and second shells need to be unfolded, the button is pressed, and the button, via a driving structure within the first shell, drives the snap-on structure to retract into the first shell, separating the snap-on structure from the snap-on slot, allowing the first and second shells to move relative to each other and unfold.

[0004] However, the button is located on the side cover of the entire device, occupying a large appearance space, reducing the flatness and smoothness of the electronic device, and affecting the appearance of the electronic device. Especially after the electronic device is folded, the button is more prominently exposed, which has a greater impact on the flatness and appearance of the electronic device. Summary of the Invention

[0005] The embodiments of the present application provide a foldable electronic device, which solves the problem in existing electronic devices where buttons are located on the sides of the entire device, occupying a large appearance space and affecting the flatness and appearance of the electronic device.

[0006] An embodiment of the present application provides a foldable electronic device, comprising: a first housing and a second housing connected in a rotatable manner, wherein the first housing comprises a side end portion and a main body portion, and when the electronic device is in a folded state, the main body portion is opposite to the second housing portion, and the side end portion is located on one side of the main body portion and the second housing portion;

[0007] A retractable snap-in piece is provided on the side end portion, and a snap-in position for cooperating with the snap-in piece is provided on the second shell. When the electronic device is in a folded state, the snap-in piece extends out of the first shell and is located in the snap-in position; thereby preventing the first shell and the second shell from rotating relative to each other, and the electronic device is locked and can be stably in the folded state for a long time.

[0008] The first housing is further provided with a button, the button being located on the main body, and when the electronic device is in a folded state, a first end of the button extends out of the first housing and is located between the first housing and the second housing;

[0009] The invention also includes a sliding member and a lever member, wherein the sliding member is slidably disposed in the first housing, the sliding direction of the sliding member is parallel to the extension and contraction direction of the clamping member, the lever member includes a rotating end and an input end and an output end respectively located on both sides of the rotating end, the lever member is rotatably disposed in the first housing via the rotating end, the second end of the button is connected to one end of the sliding member, the other end of the sliding member is connected to the input end, and the output end is connected to the clamping member;

[0010] The second shell is used to push the button to move toward the first shell, and the button drives the sliding member to slide, so that the sliding member drives the input end to move, and the output end drives the snap-in member to shrink toward the first shell, so that the snap-in member is separated from the snap-in position. That is, when it is necessary to open the electronic device, press the second shell, such as applying a pressing force in the z direction (the thickness direction of the electronic device) on the second shell. The second shell pushes the button to move along the z direction toward the first shell, and the button will drive the sliding member to slide along the x1 direction (consistent with the extension direction of the snap-in member). The sliding of the sliding member drives the input end of the lever member to move along the x1 direction, and the output end will move along the x2 direction opposite to x1. The output end drives the snap-in member to shrink toward the first shell, so that the snap-in member is separated from the snap-in position, and the first shell and the second shell can move relative to each other, so that the electronic device is opened.

[0011] By pressing the second housing to squeeze the button, the clip retracts into the first housing, opening the electronic device. The button's location within the main body of the first housing, compared to placing it on a side cover, conceals the button, reducing the apparent space occupied by the button and improving the smoothness and sleekness of the electronic device. Especially when the electronic device is folded, the button is located between the first and second housings, completely concealing the button. This significantly improves the smoothness and sleekness of the entire device, enhancing the appearance of the electronic device.

[0012] Moreover, the button is opened by squeezing the second shell, which avoids the phenomenon that the second shell bounces against the fingers or nails when pressing the button to open the electronic device, thereby improving the user experience of the electronic device. At the same time, it can reduce or avoid the occurrence of failure to open the electronic device due to contact between the second shell and the fingers, thereby improving the screen opening effect of the electronic device.

[0013] At the same time, a lever is connected between the button and the clip. A small displacement at the input end of the lever produces a larger displacement at the output end of the lever. In other words, when the button extends a small distance outside the first housing, pressing the button through the second housing can drive the clip to move a large distance into the first housing, thereby separating the clip from the clip. This can further reduce the height of the button extending outside the first housing, reducing the external space occupied by the button, and further improving the appearance of the electronic device.

[0014] In a possible implementation, the device further includes a mounting bracket and a first elastic member, wherein the mounting bracket is located in the first shell, and the clamping member is provided on the mounting bracket;

[0015] The first end of the clip extends out of the mounting bracket, and the second end of the clip is located within the mounting bracket. The second end of the clip abuts against the mounting bracket via the first elastic member. When the clip moves toward the inside of the first housing, the first elastic member is compressed. Thus, when the pressing force on the second housing is released, the compressed first elastic member rebounds, and the clip extends out of the first housing under the action of the rebound force of the first elastic member, thereby driving the output end to move. The input end drives the button in the opposite direction via the sliding member, returning the button to its original position so that it can be pressed again to activate.

[0016] In a possible implementation, a speed change member is further included, the speed change member is located in the mounting bracket and is rotatably disposed on the second end of the clamping member, and a guide member is further disposed in the mounting bracket;

[0017] The speed change member is provided with a first guide rail and a second guide rail which cooperate with the guide member. The extension direction of the first guide rail is parallel to the extension direction of the clamping member. The second guide rail is spirally arranged around the outer circumference of the speed change member, and the two ends of the first guide rail are respectively connected to the two ends of the second guide rail.

[0018] When the clamping member contracts toward the inside of the first housing, the guide member is located in the first guide rail and moves along the first guide rail;

[0019] When the clip moves under the action of the first elastic member to extend outside the first shell, the guide member is located in the second guide rail and moves along the second guide rail. That is, the first guide rail is a linear guide rail along the x-direction, and the second guide rail is a spiral guide rail that surrounds the outer circumference of the speed change member, so that the length of the second guide rail is longer than the first guide rail. When the second shell squeeze button is pressed, the button drives the clip to retract toward the first shell through the sliding member and the lever member. The guide member is located in the first guide rail and moves along the first guide rail. The movement stroke in the linear first guide rail is short, which enables the clip to quickly retract toward the first shell. When the pressing force on the second shell is removed and the clip returns to its original position under the action of the rebound force of the first elastic member, the guide member moves in the longer second guide rail. The movement stroke is longer, which can slow down the process of resetting the clip, thereby achieving slow resetting of the clip.

[0020] In this way, the first shell and the second shell can be prevented from resetting when they are opened due to the rapid rebound of the snap-fitting part. The snap-fitting part extends into the snap-fitting position, reducing or avoiding the phenomenon of failure to open the electronic device, ensuring that the electronic device can be successfully opened by pressing the button once, improving the effect of opening the screen of the electronic device and enhancing the user experience.

[0021] In one possible implementation, the first guide rail includes a moving portion and a recessed portion, the recessed portion is located on the side of the moving portion facing the first end of the clip, the moving portion and the recessed portion form a step structure, the recessed portion is connected to the second guide rail, and when the clip is separated from the clip position, the guide member is located in the recessed portion. In this way, when the clip returns to its original position under the action of the first elastic member, since the recessed portion and the moving portion form a step structure, the step structure can block and limit the guide member, and the step structure can prevent the guide member from continuing to slide along the first guide rail, thereby allowing the guide member to slide along the second guide rail, further ensuring the slow reset effect of the clip, ensuring the success rate of the electronic device opening the screen, and improving the opening effect.

[0022] In one possible implementation, a second elastic member is further included, through which the guide member is mounted on the mounting bracket. When the guide member engages with the shifting member, the second elastic member is in an elastically compressed state. The resilience of the second elastic member enables the guide member to move stably along the first or second guide rail, thereby improving the stability of the arrangement between the guide member and the shifting member. The second elastic member also helps to smoothen the guide member's transition between the first and second guide rails, enhancing the smoothness of the guide member's movement.

[0023] In one possible implementation, a limiting portion is provided on a side of the mounting bracket facing the engaging member, the second elastic member is positioned within the limiting portion, one end of the guide member engages with the first guide rail or the second guide rail, and the other end of the guide member extends into the limiting portion and abuts against the mounting bracket via the second elastic member. The limiting portion can guide and limit the second elastic member and the guide member, ensuring smooth and stable movement of the guide member within the first and second guide rails.

[0024] In one possible implementation, one end of the sliding member has an abutment portion, and the second end of the button is abutted against the abutment portion. The abutment portion is also connected to the button on a side thereof that abuts against the button, and the side of the abutment portion that abuts against the button is an inclined surface, which is inclined toward the side of the latching member and away from the lever member. Thus, when the second housing is pressed to move the button in the z direction toward the first housing, the second end of the button abuts against the inclined surface and slides relative to the inclined surface, causing the sliding member to move in the x1 direction. The sliding member then drives the input end to move, and the output end drives the latching member to move in the x2 direction. The latching member contracts into the first housing, disengaging the latching member from the latching position. This structure is simple and easy to implement.

[0025] In a possible implementation, the inclined surface is an arc-shaped surface, which can facilitate relative movement between the button and the inclined surface and make it easier for the button to drive the sliding member to move.

[0026] In a possible implementation, the method further includes rotating a transmission gear disposed in the first housing, wherein the button is provided with a first gear portion, the first gear portion extends along the first direction, and the sliding member is provided with a second gear portion, the second gear portion extends along the second direction;

[0027] The transmission gear is engaged with the first gear portion and the second gear portion respectively, so that the button drives the sliding member to move through the transmission gear.

[0028] Thus, when the button is pressed in the second housing to move in the z direction, the button drives the transmission gear to rotate via the first gear portion, and the transmission gear drives the sliding member to move in the x1 direction via the second gear portion. As a result, the button drives the sliding member via the transmission gear, and the sliding member and lever member drive the engaging member to retract into the first housing, achieving separation of the engaging member from the engaging position. The transmission gear transmission method has greater rigidity and higher movement smoothness, which helps to improve the stability and smoothness of the overall movement from the button to the engaging member.

[0029] In a possible implementation, the device further includes a connecting rod, the connecting rod being located on a side of the button facing away from the lever member, one end of the connecting rod being rotatably connected to the button, and the other end of the connecting rod being rotatably connected to the sliding member;

[0030] The connecting rod is tilted relative to the button and the sliding member, allowing the button to drive the sliding member to move via the connecting rod. When the button is pressed in the z-direction by pressing the second housing, the button drives one end of the connecting rod to move in the z-direction. The tilted connecting rod allows the other end of the connecting rod to move in the x1 direction, allowing the button to move the sliding member via the connecting rod. This allows the button to drive the sliding member via the connecting rod, which in turn drives the engaging member to retract into the first housing via the sliding member and lever member, separating the engaging member from the engaging position. This design is simple to assemble, offers good connection strength, and is highly feasible.

[0031] In a possible implementation, the invention further includes a first support member disposed in the first housing, and the rotating end is rotatably connected to the first support member, so that the lever member is rotatably disposed in the first housing.

[0032] In a possible implementation, the lever member further includes a first pin, the first pin being passed through the rotating end, and the rotating end being rotatably connected to the first support member via the first pin. This has a simple structure and high feasibility.

[0033] In one possible implementation, the mounting bracket is provided with a relief hole, through which the output end extends into the mounting bracket and connects to the clip. Passing the output end of the lever member through the relief hole and connecting to the clip helps reduce the overall height (z-direction height) of the lever member and the clip, facilitating a slimmer design for the electronic device.

[0034] In one possible implementation, the lever member further includes a second pin, which is disposed on the output end. The clamping member includes a groove for engaging with the second pin, and the output end and the clamping member are connected via the engagement of the second pin and the groove. This provides a simple structure and facilitates disassembly.

[0035] In one possible implementation, the mounting bracket has a first blocking portion on a side facing away from the second end of the clip, and the clip has a second blocking portion. The side of the second blocking portion facing away from the first elastic member abuts against the side of the first blocking portion facing the first elastic member. The abutment between the first and second blocking portions can limit the position of the clip, ensuring a stable placement of the clip within the mounting bracket and preventing the clip from detaching from the mounting bracket due to the rebound action of the first elastic member. This improves the placement stability of the clip and also enhances its telescopic stability.

[0036] In one possible implementation, the button further includes a second support member disposed within the first housing. The second support member is provided with a third guide rail extending along the first direction. The button is provided with a first stopper that cooperates with the third guide rail, and the button moves along the third guide rail via the first stopper. The first stopper can extend into and move along the third guide rail, thereby enabling the button to move along the third guide rail via the first stopper, thereby achieving movement of the button in the z-direction.

[0037] In one possible implementation, the second support member is further provided with a fourth guide rail extending in a direction parallel to the extension and retraction direction of the clamping member. The sliding member is provided with a second stopper that cooperates with the fourth guide rail, and the sliding member moves along the fourth guide rail via the second stopper. The second stopper can extend into and move along the fourth guide rail, thereby enabling the sliding member to move along the fourth guide rail via the second stopper, thereby achieving movement of the sliding member in the x-direction.

[0038] In a possible implementation, the first housing further includes a second support member disposed in the first housing, wherein a mounting portion is disposed on a side of the second support member facing away from the lever member, and the transmission gear is rotatably mounted on the mounting portion, thereby rotatably mounting the transmission gear in the first housing.

[0083] 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. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0084] Among them, the foldable electronic devices provided in the embodiments of the present application may include but are not limited to foldable fixed terminals or mobile terminals such as mobile phones, tablet computers, laptops, 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.

[0085] In the embodiment of the present application, the foldable electronic device is described as a foldable mobile phone as an example, wherein the foldable mobile phone can be a foldable mobile phone with a screen folded outward.

[0086] The foldable electronic device provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0087] Figure 1 This is a structural diagram of a foldable electronic device in a folded state provided by an embodiment of the present application. Figure 2 This is a structural diagram of a foldable electronic device in an intermediate state provided by an embodiment of the present application. Figure 3 A schematic structural diagram of a foldable electronic device in a flattened state provided in an embodiment of the present application.

[0088] See also Figure 1 and Figure 2 As shown, the foldable electronic device 100 may include at least two shells, for example, Figure 1 and Figure 2 For example, the first shell 10 and the second shell 20 in the foldable electronic device 100 are rotatably connected. Specifically, the foldable electronic device 100 may include a folding assembly 30. The first shell 10 and the second shell 20 may be located on both sides of the folding assembly 30. The first shell 10 and the second shell 20 are respectively connected to the folding assembly 30. The first shell 10 and the second shell 20 can be rotatably connected through the folding assembly 30, so that the first shell 10 and the second shell 20 can rotate relative to each other.

[0089] See also Figure 1 As shown, the first shell 10 and the second shell 20 can rotate relative to each other and fold into a closed state. For example, when the first shell 10 and the second shell 20 are in the closed state, the two can be completely closed to be parallel to each other (a slight deviation is also allowed). At this time, the electronic device 100 is in a closed state, also called a folded state.

[0090] See also Figure 2 As shown, the first housing 10 and the second housing 20 can be relatively rotated (folded or unfolded) to an intermediate state, so that the electronic device 100 is in the intermediate state.

[0091] See also Figure 3 As shown, the first shell 10 and the second shell 20 can rotate relative to each other and unfold to an open state. For example, when the first shell 10 and the second shell 20 are in the open state, the two can be roughly 180° (a slight deviation is also allowed, for example, 165°, 177° or 185°). At this time, the electronic device 100 is in an open state, also called a flattened state.

[0092] in, Figure 2 The intermediate state shown can be any state between the open state and the closed state. That is, the electronic device 100 can switch between the open state (i.e., the flattened state) and the closed state (i.e., the folded state) by moving the folding assembly 30.

[0093] In the embodiment of this application, Figure 1 and Figure 3 As shown in , when the electronic device 100 is in a flat state or a folded state, the width direction of the electronic device 100 is the x direction, the length direction of the electronic device 100 is the y direction, and the thickness direction of the electronic device 100 is the z direction.

[0094] It should be noted that the electronic device 100 may include only two shells, that is, the number of the first shell 10 and the second shell 20 may be one, so that when the electronic device 100 is in a folded state, the first shell 10 and the second shell 20 are folded relative to each other into two layers. For example, the electronic device 100 includes a first shell 10, a second shell 20 and a folding assembly 30. The first shell 10 and the second shell 20 are connected by the folding assembly 30, and the first shell 10 and the second shell 20 are folded relative to each other, so that the electronic device 100 is in a two-layer form (refer to Figure 1 shown).

[0095] Alternatively, the electronic device 100 may also include multiple shells, that is, the number of the first shell 10, the second shell 20 and the folding assembly 30 may be multiple, and the adjacent first shells 10 and the second shell 20 are connected by a folding assembly 30, so that the electronic device 100 can be folded into a multi-layer form. For example, the electronic device 100 may include two first shells 10, one second shell 20 and two folding assemblies 30, the two first shells 10 are located on both sides of the second shell 20, and the two first shells 10 are respectively rotatably connected to the second shell 20 by a folding assembly 30, one of the first shells 10 can be folded relative to the second shell 20, and the other first shell 10 can also be folded relative to the second shell 20, so that when the electronic device 100 is in a folded state, the first shell 10 and the second shell 20 are folded relative to each other into a three-layer form. When one of the first shells 10 and the second shell 20 are relatively unfolded to a flattened state (such as the two are approximately 180 degrees), the electronic device 100 is in a flattened state.

[0096] The electronic device 100 may also include a foldable flexible display screen (refer to Figure 1 ), wherein the flexible display screen can be provided on the same side surface of the first shell 10, the second shell 20 and the folding assembly 30. For example, the flexible display screen is provided on the outer side surface of the first shell 10, the second shell 20 and the folding assembly 30.

[0097] It should be noted that when the electronic device 100 is in a folded state, the two opposite surfaces of the first shell 10 and the second shell 20 are the outer surfaces of the first shell 10 and the second shell 20, respectively, and the surface of the folding component 30 on the same side as the outer surfaces of the first shell 10 and the second shell 20 is the outer surface of the folding component 30.

[0098] In some embodiments, the foldable electronic device 100 may also be a laptop computer. The laptop computer may include a first structural member and a second structural member. The first structural member and the second structural member can be folded relative to each other to a closed state, so that the laptop computer is in a closed state (i.e., a folded state). Accordingly, when the first structural member and the second structural member are unfolded relative to each other from the folded state to an open state, the laptop computer is in an open state (i.e., a flattened state). In the flattened state, at least a portion of the flexible display screen on the first structural member can be used to display images, etc., and at least a portion of the flexible display screen on the second structural member can be used as a virtual keyboard, etc.

[0099] In the embodiment of the present application, the first housing 10 and the second housing 20 may be the middle frame of the electronic device 100. The first housing 10 may include a first middle plate and a first frame, with the first frame surrounding the outer edge of the first middle plate. The second housing 20 may also include a second middle plate and a second frame, with the second frame surrounding the outer edge of the second middle plate. The folding assembly 30 may be connected to the first and second middle plates, respectively.

[0100] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or have different component arrangements. For example, the electronic device 100 may also include devices such as a camera, a flash, a processor, a memory, an antenna, a sensor, and a battery.

[0101] Figure 4 The figure is a schematic diagram of the structure of an existing foldable electronic device in an intermediate state.

[0102] To ensure that it can be stably in the folded state, in the related art, see Figure 4 As shown, a retractable snap-fit structure 1b is usually provided on the first shell 1, and a snap-fit groove 2a for cooperating with the snap-fit structure 1b is provided on the second shell 2. When the electronic device is in a folded state, the snap-fit structure 1b extends out of the first shell 1 and is located in the snap-fit groove. The first shell 1 and the second shell 2 are locked by cooperating with the snap-fit structure 1b and the snap-fit groove 2a.

[0103] A button 3 is provided on the first housing 1. Specifically, the first housing 1 typically includes a side cover 1a, which is located at a side edge of the first housing. When the electronic device is folded, the side cover 1a is located on the side of the second housing 2, and one end of the button 3 extends outside the side cover 1a, that is, the button 3 extends from the side cover 1a on the side of the entire device. When the electronic device needs to be unfolded, pressing the button 3 activates the snap structure 1b, causing it to retract into the first housing 1, thereby separating the snap structure 1b from the snap slot 2a, allowing the first and second housings 1 and 2 to rotate relative to each other and unfold.

[0104] Specifically, the driving method between the button 3 and the snap-on structure 1b is mostly achieved through a cam structure and a rolling element. The cam structure and the rolling element are both arranged in the first housing 1. The cam structure can be located below the button 3. The cam structure and the rolling element abut with an inclined surface. The rolling element and the snap-on structure are in rolling connection. When the button 3 is pressed, the button 3 pushes the cam structure to move vertically (in the z-direction). The cam structure drives the rolling element to roll and move horizontally (in the x-direction). The rolling element then drives the snap-on structure 1b to retract and move toward the inside of the first housing 1, thereby separating the snap-on structure 1b from the snap-on groove 2a.

[0105] If the button 3 is extended to the side cover 1a on the side of the entire device, the protrusion of the button 3 will occupy a larger appearance space. Especially after the electronic device is folded, the overall size of the entire device becomes smaller, and the protrusion of the button 3 is exposed and visually more prominent, which reduces the flatness and smoothness of the overall appearance of the electronic device and affects the appearance of the electronic device.

[0106] At the same time, the button 3 is located on the side cover 1a, which is located on one side of the second shell 2 and the first shell 1. The distance between the button 3 and the second shell 2 is relatively close, and when the electronic device is in the folded state, the rebound force between the first shell 1 and the second shell 2 is relatively large. When pressing the button 3 to open the first shell 1 and the second shell 2, it is easy for the second shell 2 to bounce against the finger or nail, seriously affecting the user experience when opening the electronic device. In addition, due to the contact between the second shell 2 and the finger, etc., it is possible that the snap structure will not be able to expand in time, causing it to re-enter the snap groove, resulting in failure to open the electronic device and reducing the screen opening effect.

[0107] In the embodiment of the present application, the button is set in the main body of the first shell, so that the button extends between the first shell and the second shell, and the button is pressed by pressing the second shell, that is, the button is hidden under the second shell, between the first shell and the second shell, which reduces the appearance space occupied by the button and enhances the flatness and smoothness of the whole device. Especially when the electronic device is in the folded state, combined with Figure 1 and Figure 4As shown, compared with the button extending from the side cover of the whole device, the flatness and smoothness of the appearance of the electronic device are greatly improved, and the appearance effect of the electronic device is significantly improved.

[0108] Figure 5 A schematic cross-sectional view of an electronic device according to an embodiment of the present application is provided. Figure 6 for Figure 5 A magnified view of the local structure. Figure 7 A schematic diagram of the assembly of a button and a clip provided in an embodiment of the present application.

[0109] See also Figure 5 As shown, in the embodiment of the present application, the first shell 10 includes a side end portion 10b and a main body portion 10a, and the side end portion 10b is located at a side edge of the main body portion 10a, wherein the thickness of the side end portion 10b may be greater than the thickness of the main body portion 10a (the height in the z direction). When the electronic device 100 is in a folded state, the main body portion 10a is opposite to the second shell 20, and the side end portion 10b is located on one side of the main body portion 10a and the second shell 20, that is, the side end portion 10b is located at the side edge of the entire machine, and the side end portion 10b may be flush with the second shell 20. A side end cover 10c may be provided on the side of the side end portion 10b facing away from the flexible display screen (refer to Figure 1 As shown), the side end cover 10c is a partial appearance surface of the side end portion 10b.

[0110] A retractable clip 11 may be provided on the side end 10b. The clip 11 may extend out of the first housing 10 or retract into the first housing 10. Specifically, the clip 11 may extend out of the first housing 10 from the side of the side end 10b facing the second housing 20, or retract into the first housing 10. The retractable direction of the clip 11 is parallel to the width of the electronic device 100 (the x-direction). The direction in which the clip 11 extends is x1, and the direction in which the clip 11 retracts is x2.

[0111] The second housing 20 is provided with a snap-fitting position 21 , which is used to cooperate with the snap-fitting member 11 . Specifically, the snap-fitting position 21 may be a snap-fitting groove or other snap-fitting structural members.

[0112] When the electronic device 100 is in the folded state, see Figure 5 As shown, the snap-fit member 11 extends out of the first shell 10 and extends into the snap-fit position 21, cooperating with the snap-fit position 21, so that the first shell 10 and the second shell 20 cannot rotate relative to each other, and the electronic device 100 is locked and can be stably in the folded state for a long time.

[0113] A button 12 is also provided on the first housing 10. The button 12 is located on the main body 10a and extends to the side of the first housing 10 facing away from the flexible display screen (see FIG. Figure 3 As shown), and when the electronic device 100 is in the folded state, see Figure 5 As shown, the first end of the button 12 extends out of the first housing 10 and is located between the first housing 10 and the second housing 20. When the second housing 20 is squeezed, the button 12 can be squeezed through the second housing 20 to open the button 12.

[0114] For details, see Figure 6 As shown, a sliding member 13 and a lever member 14 are also provided in the first shell 10. The sliding member 13 is slidably provided in the first shell 10, wherein the sliding direction of the sliding member 13 is parallel to the telescopic direction of the clamping member 11, that is, the sliding member 13 moves in a direction parallel to x.

[0115] Combine Figure 7 As shown, the lever member 14 includes a rotating end 141, an input end 142, and an output end 143, wherein the input end 142 and the output end 143 are respectively located on either side of the rotating end 141. The lever member 14 is rotatably disposed within the first housing 10 via the rotating end 141, i.e., the input end 142 and the output end 143 are capable of rotating about the rotating end 141. The second end of the button 12 is connected to one end of the slider 13, the other end of the slider 13 is connected to the input end 142 of the lever member 14, and the output end 143 of the lever member 14 is connected to the engaging member 11.

[0116] Combine Figure 6 and Figure 7 As shown, when the electronic device 100 needs to be opened, the second housing 20 is pressed, such as applying pressure on the second housing 20. Figure 6 The second housing 20 pushes the button 12 to move in the first direction toward the inside of the first housing 10, and the button 12 drives the slider 13 to slide in the second direction. The second direction is consistent with the extension direction of the latch 11, and the first direction is perpendicular to the second direction. That is, the button 12 moves in the z direction and drives the slider 13 to slide in the x1 direction.

[0117] The sliding member 13 slides and drives the input end 142 of the lever member 14 to move along the x1 direction, and the output end 143 will move along the x2 direction opposite to x1. The output end 143 drives the clamping member 11 to retract toward the first shell 10, so that the clamping member 11 is separated from the clamping position 21. The first shell 10 and the second shell 20 can move relative to each other, so that the electronic device 100 can be opened.

[0118] By pressing the second shell 20 to squeeze the button 12, the clip 11 can be retracted toward the inside of the first shell 10, thereby opening the electronic device 100. The button 12 is located in the main body 10a of the first shell 10. Compared with the related art in which the button 12 extends from the side end 10b, the position of the button 12 is hidden, which can reduce the appearance space occupied by the button 12 and improve the flatness and smoothness of the electronic device 100. In particular, when the electronic device 100 is in the folded state, the button 12 is located between the first shell 10 and the second shell 20, which achieves the concealment of the button 12, significantly improving the flatness and smoothness of the entire device and enhancing the appearance of the electronic device 100.

[0119] Moreover, the button 12 is opened by squeezing the second shell 20, thereby avoiding the phenomenon that the second shell 20 bounces onto the finger or nail when pressing the button 12 to open the electronic device 100, thereby improving the user experience of the electronic device 100. At the same time, it can reduce or avoid the occurrence of the electronic device 100 failing to open due to the contact between the second shell 20 and the finger, thereby improving the screen opening effect of the electronic device 100.

[0120] At the same time, a lever member 14 is connected between the button 12 and the snap-on member 11. When a small displacement is input at the input end 142 of the lever member 14, a larger displacement can be generated at the output end 143 of the lever member 14. That is to say, the button 12 produces a small displacement, and the button 12 drives the input end 142 to move through the sliding member 13. After passing through the lever member 14, the output end 143 can drive the snap-on member 11 to produce a larger contraction displacement. That is, when the distance that the button 12 extends outside the first shell 10 is small, pressing the button 12 through the second shell 20 can drive the snap-on member 11 to move and contract a larger distance toward the inside of the first shell 10, thereby realizing the separation of the snap-on member 11 from the snap-on position 21.

[0121] For example, the height of the button 12 extending from the first housing 10 is 0.3 mm (i.e., the movement distance of the button 12 in the z-direction when pressed is 0.3 mm). The distance that the latching member 11 is retracted into the first housing 10 by the slider 13 and the lever 14 can reach 1 mm (i.e., the movement distance of the latching member 11 in the x2-direction is 1 mm). This can further reduce the height of the button 12 extending from the first housing 10, reduce the external space occupied by the button 12, and further enhance the appearance of the electronic device 100.

[0122] Figure 8 This is a schematic diagram of an assembly of a mounting bracket, a button, and a clip provided in an embodiment of the present application. Figure 9 This is an exploded schematic diagram of a mounting bracket, a button, and a clip provided in an embodiment of the present application. Figure 10A cross-sectional diagram of an assembly of a mounting bracket, a button, and a clip provided in an embodiment of the present application is shown. Figure 11 A schematic diagram of the structure of a transmission provided in an embodiment of the present application at one viewing angle is shown. Figure 12 A schematic structural diagram of a transmission component provided in an embodiment of the present application from another perspective.

[0123] See also Figure 8 As shown, the foldable electronic device 100 further includes a mounting bracket 15 and a first elastic member 16, wherein the mounting bracket 15 is disposed in the first housing 10 (refer to Figure 6 As shown), the clip 11 is arranged on the mounting bracket 15.

[0124] The first end of the clip 11 extends out of the mounting bracket 15 and the first end of the clip 11 extends out of the first shell 10 . When the electronic device 100 is in the first state, the first end of the clip 11 extends into the clip position 21 of the second shell 20 .

[0125] The second end of the clip 11 is located in the mounting bracket 15, and the second end of the clip 11 abuts against the inner wall of the mounting bracket 15 through the first elastic member 16. When the button 12 is squeezed toward the first shell 10 by pressing the second shell 20, the button 12 drives the sliding member 13 to move, the sliding member 13 drives the input end 142 to move, and the output end 143 drives the clip 11 to shrink toward the first shell 10. That is, when the clip 11 shrinks toward the mounting bracket 15, the first elastic member 16 is compressed by the clip 11.

[0126] In this way, when the pressing force on the second shell 20 is removed, the compressed first elastic member 16 will rebound and recover, and the clamping member 11 will be able to extend toward the outside of the first shell 10 under the action of the rebound force of the first elastic member 16, thereby driving the output end 143 to move, and the input end 142 drives the button 12 to move in the opposite direction through the sliding member 13, so that the button 12 returns to its original position, so that the button 12 can be pressed again to open it.

[0127] See also Figure 9 As shown, a third limiting member 113 can be provided on the second end of the clamping member 11, and the first elastic member 16 can be sleeved on the third limiting member 113. The third limiting member 113 can not only fix the first elastic member 16, but also guide the extension and contraction of the first elastic member 16.

[0128] Continue to see Figure 9 As shown, the foldable electronic device 100 further includes a transmission member 17, Figure 10As shown, the speed change member 17 is located in the mounting bracket 15, and the speed change member 17 can be rotatably set on the second end of the clamping member 11. A guide member 151 is also provided in the mounting bracket 15. Specifically, a guide member 151 is provided on the surface of the inner wall of the mounting bracket 15 facing the second end of the clamping member 11.

[0129] A support rod 114 may be provided on the second end of the clamping member 11, and an assembly hole 173 may be provided on the speed change member 17 (see FIG. Figure 11 As shown in FIG1 , the speed change member 17 is sleeved on the support rod 114 through the assembly hole 173 and is rotatably arranged relative to the support rod 114. A blocking member 1141 may also be provided on the support rod 114. The blocking member 1141 is located on the side of the speed change member 17 facing away from the first end of the clamping member 11. The outer circumference of the blocking member 1141 may be larger than the inner circumference of the assembly hole, so that the blocking member 1141 acts as a limit block for the speed change member 17, preventing the speed change member 17 from falling off the support rod during rotation, thereby improving the installation stability of the speed change member 17.

[0130] See also Figure 11 and Figure 12 As shown, the speed change member 17 is provided with a first guide rail 171 and a second guide rail 17, and the guide member 151 can cooperate with the first guide rail 171 and the second guide rail 17 respectively, that is, the guide member 151 can extend into the first guide rail 171 and move along the first guide rail 171, and the guide member 151 can also extend into the second guide rail 17 and move along the second guide rail 17.

[0131] The two ends of the first guide rail 171 are respectively connected to the two ends of the second guide rail 17, such as the head end of the first guide rail 171 (the side facing away from the first end of the clamp 11) can be connected to the tail end of the second guide rail 17, and the tail end of the first guide rail 171 (the side facing the first end of the clamp 11) can be connected to the head end of the second guide rail 17.

[0132] The extension direction of the first guide rail 171 is parallel to the extension direction of the clamping member 11, that is, the first guide rail 171 is a linear guide rail along the x direction (refer to Figure 14 As shown in FIG. 1 , the second guide rail 17 is spirally arranged around the outer circumference of the transmission member 17. That is, the second guide rail 17 is a spiral guide that surrounds the outer circumference of the transmission member 17. In other words, the first guide rail 171 on the transmission member 17 is connected to the second guide rail 17 at both ends. The first guide rail 171 is a linear guide, and the second guide rail 17 is a spiral guide. Thus, the second guide rail 17 is longer than the first guide rail 171.

[0133] Figure 13 This is a schematic diagram of the structure of a guide member and a first guide rail of a transmission member provided in an embodiment of the present application. Figure 14This is a structural diagram of a clamping member provided in an embodiment of the present application when it is retracted into the first housing. Figure 15 This is a schematic diagram of the structure of the cooperation between a guide member and a second guide rail of a transmission member provided in an embodiment of the present application. Figure 16 This is a structural diagram of a clamping member provided in an embodiment of the present application when it extends outward from the first housing. Figure 17 A schematic cross-sectional structure diagram of a transmission component provided in an embodiment of the present application.

[0134] See also Figure 13 and Figure 14 As shown, when the second housing 20 is pressed to squeeze the button 12, the button 12 drives the clip 11 to retract toward the first housing 10 through the sliding member 13 and the lever member 14. The guide member 151 is located in the first guide rail 171 and moves along the first guide rail 171. The guide member 151 moves from the head end of the first guide rail 171 to the tail end of the first guide rail 171. At this time, the clip 11 retracts into the first housing 10. The movement distance within the linear first guide rail 171 is short, which enables the clip 11 to retract quickly toward the first housing 10.

[0135] See also Figure 15 and Figure 16 When the pressing force on the second housing 20 is removed, the clip 11 moves under the action of the first elastic member 16, thereby extending out of the first housing 10. The tail end of the first guide rail 171 is connected to the head end of the second guide rail 17, allowing the guide member 151 to be located within the second guide rail 17 and move along the second guide rail 17. In other words, when the clip 11 returns to its original position under the action of the rebound force of the first elastic member 16, the guide member 151 moves within the longer second guide rail 17, with a longer movement stroke, which can slow down the resetting process of the clip 11 and achieve a slow resetting of the clip 11.

[0136] In this way, the first shell 10 and the second shell 20 can be prevented from resetting when they are opened due to the rapid rebound of the snap-fit member 11. The snap-fit member 11 extends into the snap-fit position 21, reducing or avoiding the phenomenon of failure to open the electronic device 100, ensuring that the electronic device 100 can be successfully opened by pressing the button 12 once, improving the effect of opening the screen of the electronic device 100 and enhancing the user experience.

[0137] In order to ensure the switching of the guide member 151 between the first guide rail 171 and the second guide rail 17, see Figure 17 As shown, the first guide rail 171 may include a moving portion 1711 and a recessed portion 1712, wherein the recessed portion 1712 is located on a side of the moving portion 1711 facing the first end of the clamping member 11 (see FIG. Figure 13 As shown), that is, the recessed portion 1712 is located at the tail end of the first guide rail 171, and the recessed portion 1712 is connected to the second guide rail 17;

[0138] A stepped structure 1713 is formed between the recessed portion 1712 and the movable portion 1711. Specifically, the bottom wall of the recessed portion 1712 is closer to the positioning hole of the transmission member 17 than the movable portion 1711, thereby forming a stepped structure 1713 between the recessed portion 1712 and the movable portion 1711. When the engaging member 11 retracts toward the inside of the first housing 10, the guide member 151 moves from the leading end to the trailing end of the first guide rail 171. Finally, when the engaging member 11 and the engaging portion 21 are separated, the guide member 151 is located in the recessed portion 1712 at the trailing end.

[0139] When the snap-in component 11 returns to its original position under the action of the first elastic component 16, since the recessed portion 1712 and the movable portion 1711 form a step structure 1713, the step structure 1713 can block and limit the guide component 151. The step structure 1713 can prevent the guide component 151 from continuing to slide along the first guide rail 171, thereby causing the guide component 151 to slide along the second guide rail 17, further ensuring the slow reset effect of the snap-in component 11, ensuring the success rate of the screen opening of the electronic device 100, and improving the screen opening effect.

[0140] In some examples, a prompt member can be set in the electronic device 100. When the guide member 151 slides into the recessed portion 1712, the snap-in member 11 separates from the snap-in position 21, and the prompt member can emit a prompt sound to remind the user, further ensuring the success rate of the electronic device 100 in opening the screen and improving the user experience.

[0141] Figure 18 A schematic cross-sectional structure diagram of a mounting bracket and a clamping member provided in an embodiment of the present application.

[0142] See also Figure 18 As shown, the foldable electronic device 100 may further include a second elastic member 18 , and the guide member 151 is disposed on the mounting bracket 15 through the second elastic member 18 .

[0143] It should be noted that after the guide member 151 is engaged with the shift member 17, the second elastic member 18 should be in an elastically compressed state. The rebound force of the second elastic member 18 enables the guide member 151 to move stably along the first guide rail 171 or the second guide rail 17, thereby improving the stability of the arrangement between the guide member 151 and the shift member 17. Furthermore, the second elastic member 18 helps to improve the smoothness of the guide member 151 switching between the first guide rail 171 and the second guide rail 17, thereby improving the stability of the movement of the guide member 151.

[0144] Specifically, a limiting portion 152 may be provided on the side of the mounting bracket 15 facing the clamping member 11. The second elastic member 18 may be located within the limiting portion 152. One end of the guide member 151 engages with the first guide rail 171 or the second guide rail 17, while the other end of the guide member 151 extends into the limiting portion 152 and abuts against the mounting bracket 15 via the second elastic member 18. The limiting portion 152 can guide and limit the second elastic member 18 and the guide member 151, ensuring smooth and stable movement of the guide member 151 within the first guide rail 171 and the second guide rail 17.

[0145] Continue to see Figure 18 As shown, a clearance hole 153 is further defined in the mounting bracket 15. The clip 11 is located within the mounting bracket 15, allowing the output end 143 of the lever member 14 to pass through the clearance hole 153 and extend into the mounting bracket 15, thereby achieving connection between the output end 143 and the clip 11. Passing the output end 143 of the lever member 14 through the clearance hole 153 and connecting with the clip 11 helps reduce the overall height (z-direction height) of the lever member 14 and the clip 11, thereby facilitating a slimmer design for the electronic device 100.

[0146] Among them, see Figure 18 As shown, the mounting bracket 15 has a first blocking portion 154 on the side facing away from the second end of the clip 11, and the clip 11 has a second blocking portion 112. The side of the second blocking portion 112 facing away from the first elastic member 16 abuts against the side of the first blocking portion 154 facing the first elastic member 16. This abutment between the first blocking portion 154 and the second blocking portion 112 restricts the position of the clip 11, ensuring that the clip 11 is stably positioned within the mounting bracket 15 and preventing the clip 11 from being disengaged from the mounting bracket 15 due to the rebound action of the first elastic member 16. This improves the stability of the clip 11 and its telescopic stability.

[0147] Figure 19 This is a schematic diagram of an exploded view of a snap-on component, a sliding component, a lever, and a button provided in an embodiment of the present application.

[0148] See also Figure 19 As shown, the foldable electronic device 100 also includes a first support member 120, wherein the first support member 120 can be arranged in the first shell 10, and a first mounting hole 1201 can be opened on the first support member 120. The electronic device 100 can also include a first fastener (not shown in the figure), which can pass through the first mounting hole 1201 and fixedly cooperate with the first shell 10, thereby setting the first support member 120 on the first shell 10.

[0149] The rotating end 141 of the lever member 14 can be rotatably connected to the first support member 120, so that the lever member 14 is rotatably arranged in the first housing 10. A first support member 120 can be provided on both sides of the lever member 14 to improve the arrangement stability of the lever member 14.

[0150] The lever member 14 may further include a first pin 130, which may be inserted into the rotating end 141. A first matching hole 1203 is provided on the first support member 120, and the rotating end 141 may be rotatably connected to the first support member 120 through the rotational engagement of the first pin 130 and the first matching hole 1203.

[0151] Continue to see Figure 19 As shown, the lever member 14 can also include a second pin shaft 140, which is passed through the output end 143, and a coordination groove 111 is provided on the clamping member 11. Specifically, coordination grooves 111 are respectively provided on the opposite sides of the clamping member 11, and the two ends of the second pin shaft 140 are engaged with the coordination groove 111, so that the output end 143 is connected to the clamping member 11 through the cooperation of the second pin shaft 140 and the coordination groove 111, so that the output end 143 can drive the clamping member 11 to move.

[0152] A third coordination hole 1421 can be opened on the input end 142 of the lever member 14, and a coordination rod 134 is provided on the sliding member 13. The sliding member 13 can be connected to the input end 142 through the coordination rod 134 and the third coordination hole 1421, so that the sliding member 13 can drive the input end 142 to move.

[0153] The foldable electronic device 100 may further include a second support member 150, which is disposed in the first shell 10. For example, a second mounting hole 1504 may be provided on the second support member 150. The electronic device 100 may further include a second fastener (not shown in the figure), which may pass through the second mounting hole and be fixedly engaged with the first shell 10, thereby disposing the second support member 150 on the first shell 10.

[0154] A third guide rail 1501 may be provided on the second support member 150, and the third guide rail 1501 extends along the first direction, that is, the z direction. A first limiting member 122 is provided on the button 12, and the first limiting member 122 cooperates with the third guide rail 1501. The first limiting member 122 can extend into the third guide rail 1501 and move along the third guide rail 1501, so that the button 12 moves along the third guide rail 1501 through the first limiting member 122, thereby realizing the movement of the button 12 in the z direction.

[0155] The third guide rail 1501 serves to guide and limit the movement of the button 12 , thereby improving the accuracy of the movement of the button 12 and further ensuring the success rate of opening the electronic device 100 .

[0156] A second support member 150 may be provided on both sides of the button 12 to improve the movement stability of the button 12 .

[0157] Continue to see Figure 19 As shown, a fourth guide rail 1502 is further provided on the second support member 150, and the extension direction of the fourth guide rail 1502 is parallel to the extension and contraction direction of the clamping member 11, that is, the fourth guide rail 1502 extends along the x-direction, and a second limiting member 133 can be provided on the sliding member 13, and the second limiting member 133 cooperates with the fourth guide rail 1502. The second limiting member 133 can extend into the fourth guide rail 1502 and move along the fourth guide rail 1502, so that the sliding member 13 moves along the fourth guide rail 1502 through the second limiting member 133, thereby realizing the movement of the sliding member 13 in the x-direction.

[0158] In the embodiment of the present application, the button 12 is moved along the z direction by pressing the second shell 20 , and the button 12 drives the sliding member 13 to move along the x direction. There are many ways of driving cooperation between the button 12 and the sliding member 13 .

[0159] Figure 20 A schematic diagram of the cooperation of a button, a sliding member, a lever member and a snap-on member provided in an embodiment of the present application is shown. Figure 21 This is a schematic structural diagram of a sliding member provided in an embodiment of the present application. Figure 22 A schematic cross-sectional structure diagram of the cooperation of a button, a sliding member, a lever member and a snap-on member provided in an embodiment of the present application.

[0160] In one possible implementation, see Figure 20 and Figure 21 As shown, a contact portion 131 is provided on one end of the sliding member 13 , and a second end of the button 12 is in contact with the contact portion 131 .

[0161] Combine Figure 22 As shown, the side of the abutting portion 131 that abuts the button 12 is an inclined surface 131a. The side of the inclined surface 131a facing the engaging member 11 is inclined in a direction away from the lever member 14. When the second housing 20 is pressed to move the button 12 along the z direction toward the first housing 10, the second end of the button 12 abuts against the inclined surface 131a and slides relative to the inclined surface 131a, thereby causing the slider 13 to move in the x1 direction. The slider 13 drives the input end 142 to move, and the output end 143 drives the engaging member 11 to move in the x2 direction. The engaging member 11 contracts toward the inside of the first housing 10, thereby disengaging the engaging member 11 from the engaging portion 21. The structure is simple and easy to implement.

[0162] The inclined surface 131 a on the abutting portion 131 may be an arc-shaped surface, which can facilitate relative movement between the button 12 and the inclined surface 131 a and make it easier for the button 12 to drive the sliding member 13 to move.

[0163] The abutment portion 131 may be located on the side of the button 12 facing away from the lever member 14. The abutment portion 131 may be integrally formed on the sliding member 13 when the sliding member 13 is formed. Alternatively, the abutment portion 131 may be provided on the sliding member 13 after being formed.

[0164] Figure 23 This is a schematic diagram of another button, sliding member, lever member and snap-on member provided in an embodiment of the present application. Figure 24 This is a partially exploded schematic diagram of another button and sliding member provided in an embodiment of the present application. Figure 25 A schematic cross-sectional structure diagram of another button, sliding member, lever member and snap-on member provided in an embodiment of the present application.

[0165] In another possible embodiment, see Figure 23 As shown, the foldable electronic device 100 may include a transmission gear 19 , which is rotatably disposed in the first housing 10 , wherein the transmission gear 19 may be located on a side of the button 12 facing away from the lever 14 .

[0166] Specific, combined Figure 24 As shown, a mounting portion 1503 can be provided on the side of the second support member 150 facing away from the lever member 14, and a fourth matching hole 1503a can be provided on the mounting portion 1503. The rotating shaft 191 of the transmission gear 19 can cooperate with the fourth matching hole 1503a, so that the transmission gear 19 is rotatably set on the mounting portion 1503.

[0167] The button 12 is provided with a first gear portion 121. Specifically, the first gear portion 121 is provided on the side of the button 12 facing away from the lever member 14. The first gear portion 121 extends along a first direction (z direction). The sliding member 13 is provided with a second gear portion 132. The second gear portion 132 extends along a second direction (x1 direction).

[0168] Combine Figure 25As shown, the transmission gear 19 is respectively engaged with the first gear portion 121 and the second gear portion 132. When the button 12 is squeezed by pressing the second shell 20 to move along the z direction, the button 12 drives the transmission gear 19 to rotate through the first gear portion 121, and the transmission gear 19 drives the sliding member 13 to move along the x1 direction through the second gear portion 132, so that the button 12 drives the sliding member 13 to move through the transmission gear 19, and then drives the locking member 11 to retract toward the inside of the first shell 10 through the sliding member 13 and the lever member 14, thereby realizing the separation of the locking member 11 from the locking position 21.

[0169] The button 12 drives the sliding part 13 to move through the transmission gear 19, and then drives the clamping part 11 to retract toward the first shell 10. The transmission method of the transmission gear 19 has greater rigidity and higher movement smoothness, which helps to improve the stability and smoothness of the overall movement from the button 12 to the clamping part 11.

[0170] The distribution length of the first gear portion 121 on the button 12 and the distribution length of the second gear portion 132 on the sliding member 13 are not limited in the embodiment of the present application and can be selected and set according to the movement travel requirements of the button 12 and the clamping member 11.

[0171] Figure 26 A schematic diagram of the cooperation of another button, sliding member, lever member and snap-on member provided in an embodiment of the present application is shown. Figure 27 A partially exploded schematic diagram of another button and slider provided in an embodiment of the present application. Figure 28 A schematic cross-sectional structure diagram of another button, sliding member, lever member and snap-on member provided in an embodiment of the present application.

[0172] In another possible embodiment, see Figure 26 As shown, the foldable electronic device 100 may include a link member 110 , which is located on a side of the button 12 facing away from the lever member 14 .

[0173] One end of the connecting rod 110 is rotatably connected to the button 12, and the other end of the connecting rod 110 is rotatably connected to the sliding member 13. Figure 27 As shown, a first assembly portion 123 can be provided on the end of the button 12 facing away from the lever member 14, and the electronic device 100 can include a third pin shaft 160. The connecting rod member 110 can be rotatably provided on the first assembly portion through the third pin shaft, thereby realizing a rotational connection between the connecting rod member 110 and the button 12.

[0174] A second assembly portion 135 may be provided on the sliding member 13 , and the electronic device 100 may further include a fourth pin 170 . The connecting rod 110 may be rotatably provided on the second assembly portion via the fourth pin, thereby achieving a rotational connection between the connecting rod 110 and the sliding member 13 .

[0175] Combine Figure 28 As shown, the two ends of the connecting rod 110 are rotatably connected to the button 12 and the sliding member 13, respectively, and the connecting rod 110 is tilted relative to the button 12 and the sliding member 13. When the second housing 20 is pressed to squeeze the button 12 and cause it to move in the z-direction, the button 12 drives one end of the connecting rod 110 to move in the z-direction. Since the connecting rod 110 is tilted, the other end of the connecting rod 110 drives the sliding member 13 to move in the x1 direction, so that the button 12 can drive the sliding member 13 to move through the connecting rod 110. The button 12 can then drive the sliding member 13 to move through the connecting rod 110, and then the sliding member 13 and the lever member 14 drive the engaging member 11 to retract toward the inside of the first housing 10, achieving separation of the engaging member 11 from the engaging position 21. The assembly is simple, the connection strength is good, and the feasibility is high.

[0176] The tilt angles between the connecting rod 110 and the button 12 and the sliding member 13 are not limited in the embodiment of the present application and can be selected and set according to the movement travel requirements of the button 12 and the engaging member 11 .
