Description

Electronic device

[0001] The present application claims priority to the Chinese patent application No. 202410825745.5, filed on June 24, 2024, with the State Intellectual Property Office of China, with the title of "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of foldable electronic products, in particular to an electronic device. BACKGROUND

[0003] With the development of technology and the demand of electronic device market, foldable electronic devices are more and more widely used. The traditional foldable electronic device includes a flexible screen and a folding mechanism. The folding mechanism includes a middle shell. A gap is reserved between the T-shaped block of the middle shell and the flexible screen, which can prevent the flexible screen from being scratched or impacted by the T-shaped block. However, the gap is easy to make external dust, sand and other foreign matters enter the inside of the electronic device. In order to achieve dust prevention, the traditional foldable electronic device sets a rubber block at the gap. However, since the rubber block is easy to age, the external foreign matters still enter between the folding mechanism and the flexible screen through the gap. Therefore, on the one hand, the rubber block still cannot effectively prevent dust, and on the other hand, since the foreign matters are located between the folding mechanism and the flexible screen, when the user presses the flexible screen, the flexible screen will directly contact the foreign matters and be damaged, and the service life of the flexible screen is short. SUMMARY

[0004] The present application provides an electronic device which can not only prevent external foreign matters from entering the inside of the electronic device, but also ensure that the flexible screen is not easy to be damaged.

[0005] The present application provides an electronic device. The electronic device includes a first shell, a second shell, a folding mechanism, a flexible screen and a first shielding member, the flexible screen and the first shielding member can be folded; the folding mechanism connects the first shell and the second shell, and the folding mechanism can make the first shell and the second shell relatively unfold and fold; the flexible screen includes a first display area, a second display area and a third display area, the first display area is fixed to the first shell, the third display area is fixed to the second shell, and the second display area is arranged opposite to the folding mechanism; the folding mechanism includes a middle shell, the middle shell includes a base and a first end block, the base extends along the length extension direction of the middle shell, the base is arranged opposite to the second display area, the first end block is protruded at one end of the base and protrudes towards the second display area, the first end block is arranged spaced apart from the edge of the second display area and forms a first gap; a part of the first shielding member is located between the base and the second display area, and a part of the first shielding member extends outwards through the edge of the second display area towards the first end block and covers at least part of the first gap.

[0006] It can be understood that, by shielding at least part of the first gap by the first shielding member, on the one hand, dust and other foreign matters in the external environment of the electronic device are prevented from entering the internal of the electronic device through the first gap, and on the other hand, the appearance consistency of the electronic device is better, so that the user is not easily affected by the use experience due to the appearance of the electronic device having a gap when using the electronic device. In addition, even if some tiny dust enters the internal of the electronic device through the first gap, the first shielding member can separate the tiny dust from the flexible screen, so that the flexible screen is not damaged due to direct contact with dust and other foreign matters in the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0007] It can be understood that, since the first shielding member is located in the internal of the electronic device, the first shielding member will not affect the appearance of the electronic device due to leakage to the external of the electronic device. In this way, the appearance of the electronic device is more concise, and the user experience is better.

[0008] It can be understood that, compared with the scheme of shielding the first gap by the rubber block, by setting a part of the first shielding member between the base and the second display area, a part of the first shielding member extends towards the first end block through the edge of the second display area, and at least part of the first gap is shielded, thereby solving the problems of increasing the thickness of the electronic device, the rubber block being easy to age, and poor reliability existing in the scheme of shielding the first gap by the rubber block. At this time, on the one hand, the electronic device can be thinned, on the other hand, the first shielding member is not easy to scratch the user's hand, which is conducive to improving the user experience of the electronic device, and on the other hand, the first shielding member is located in the internal of the electronic device, and the first shielding member is not easy to be damaged by environmental factors of the electronic device, and the reliability of the first shielding member is better.

[0009] In a possible implementation manner, in the length extension direction of the middle shell, the shortest distance between the edge of the first shielding member close to the first end block and the side surface of the first end block close to the first shielding member is L, and L satisfies: L≤0.2mm.

[0010] It can be understood that the first shielding member can better shield the first gap, and foreign matters in the external environment of the electronic device are less likely to enter the internal of the electronic device through the first gap.

[0011] In a possible implementation manner, the first shielding member includes a first part and a second part; the first part is located between the first shell and the first display area, and the first part is fixed to the first shell; a part of the second part is located between the base and the second display area, and a part of the second part extends towards the first end block through the edge of the second display area and covers at least part of the first gap.

[0012] It can be understood that the first part of the first shielding member is fixedly connected to the first shell, and the second part of the first shielding member is not fixedly connected to the base, so that part of the first shielding member forms a fixed end and part of the first shielding member forms a movable end. In this way, during unfolding or folding of the electronic device, the first shielding member is not prone to dislocation to ensure that the first shielding member is not prone to dislocation.

[0013] It can be understood that the second part shields at least part of the first gap, which can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal of the electronic device through the first gap, and can make the appearance consistency of the electronic device better, so that the user is not prone to affecting the use experience due to the appearance of the electronic device having a gap when using the electronic device. In addition, even if some tiny dust enters the internal of the electronic device through the first gap, the first shielding member can separate the tiny dust from the flexible screen, so that the flexible screen will not be damaged due to direct contact with the dust and other foreign matters during pressing of the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0014] In a possible implementation, the first shielding member includes a first part and a second part; the first part is located between the first shell and the first display area, and the first part is fixed to the first display area; part of the second part is located between the base and the second display area, and part of the second part extends towards the first end block through the edge of the second display area and covers at least part of the first gap.

[0015] It can be understood that the first part of the first shielding member is fixedly connected to the first display area, and the second part of the first shielding member is not fixedly connected to the base, so that part of the first shielding member forms a fixed end. In this way, during unfolding or folding of the electronic device, the first shielding member is not prone to dislocation to ensure that the first shielding member is not prone to dislocation.

[0016] It can be understood that the second part shields at least part of the first gap, which can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal of the electronic device through the first gap, and can make the appearance consistency of the electronic device better, so that the user is not prone to affecting the use experience due to the appearance of the electronic device having a gap when using the electronic device. In addition, even if some tiny dust enters the internal of the electronic device through the first gap, the first shielding member can separate the tiny dust from the flexible screen, so that the flexible screen will not be damaged due to direct contact with the dust and other foreign matters during pressing of the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0017] In a possible implementation, the first shielding member includes an adhesive, and the adhesive fixedly connects the first part and the first shell.

[0018] Understandably, the adhesive backing can fix the first shielding component to the first housing, so that the first shielding component is not easy to move during the unfolding or folding of the electronic device, thus ensuring that the first shielding component is not easily misaligned.

[0019] In one possible implementation, the first shielding element includes an adhesive backing that securely connects the first part to the flexible screen.

[0020] Understandably, the adhesive backing can fix the first shielding component to the flexible screen, so that the first shielding component is not easy to move during the unfolding or folding of the electronic device, thus ensuring that the first shielding component is not easily misaligned.

[0021] In one possible implementation, the second part includes a connecting part and a shielding part. The connecting part connects to the first part, and the shielding part protrudes from one side of the connecting part and protrudes towards the first end block. The connecting part is located between the base and the second display area. A portion of the shielding part is located between the base and the second display area, and a portion extends from the edge of the second display area towards the first end block and covers at least a portion of the first gap. The first part, the shielding part, and the first housing enclose a first clearance space, which is used to arrange components of the electronic device.

[0022] Understandably, the first shielding component covers at least a portion of the first gap. This serves two purposes: firstly, it prevents dust and other foreign objects from the external environment from entering the electronic device through the gap; secondly, it ensures a more uniform appearance of the electronic device, making it less likely for users to experience a negative impact on their experience due to gaps in the device's appearance. Furthermore, even if tiny specks of dust do enter the device through the gap, the first shielding component can keep them away from the flexible screen. This prevents the flexible screen from being damaged by direct contact with dust or other foreign objects when the user presses it, thus significantly improving the screen's lifespan and reliability.

[0023] Understandably, since the first shielding component is located inside the electronic device, its appearance will not be affected by being exposed to the outside of the device. This results in a cleaner overall appearance and a better user experience.

[0024] Understandably, the first clearance space can provide space for the arrangement of electronic device components, thereby improving the space utilization of electronic devices in the thickness direction.

[0025] In one possible implementation, the first shielding member further includes a third part located on the side of the second part away from the first part and connected to the second part; the third part is located between the second housing and the third display area.

[0026] It can be understood that the third part of the first shielding member is not fixedly connected with the second housing and the third display area, so that a part of the first shielding member forms a fixed end and another part forms a movable end. In this way, in the unfolding or folding process of the electronic device, the first shielding member is not prone to dislocation and can have sufficient deformation space to ensure that the first shielding member is not prone to dislocation or breakage.

[0027] In a possible implementation, when the electronic device is in the unfolded state, the first display area, the second display area and the third display area are flat, the first part, the second part and the third part of the first shielding member are flat, the first part is attached between the first housing and the first display area, the third part is attached between the second housing and the third display area, a part of the second part is attached between the folding mechanism and the second display area, and another part of the second part extends out of the edge of the second display area towards the first end block and covers at least part of the first gap; when the electronic device is in the folded state, the second part and the second display area are bent, the first display area is arranged opposite to the second display area, the first part is attached between the first housing and the first display area, the third part is attached between the second housing and the third display area, a part of the second part is attached between the folding mechanism and the second display area, and another part of the second part extends out of the edge of the second display area towards the first end block and covers at least part of the first gap.

[0028] It can be understood that although the first part of the first shielding member is not connected with the first housing, the first housing can push the first part of the first shielding member towards the first display area of the flexible screen, so that the first part of the first shielding member is not prone to dislocation and shaking, regardless of whether the electronic device is in the unfolded state or the folded state.

[0029] It can be understood that although the second part of the first shielding member is not fixedly connected with the folding mechanism and the second display area, the folding mechanism can push the second part of the first shielding member towards the second display area of the flexible screen, so that the second part of the first shielding member is not prone to dislocation and shaking, regardless of whether the electronic device is in the unfolded state or the folded state.

[0030] It can be understood that although the third part of the first shielding member is not connected with the second housing, the second housing can push the third part of the first shielding member towards the third display area of the flexible screen, so that the third part of the first shielding member is not prone to dislocation and shaking, regardless of whether the electronic device is in the unfolded state or the folded state.

[0031] It can be understood that the second part of the first shielding member shields at least part of the first gap, which can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal of the electronic device through the first gap, and can make the appearance of the electronic device more consistent, so that the user is less likely to be affected by the use experience due to the appearance of the electronic device having a gap when using the electronic device. In addition, even if some small dust enters the internal of the electronic device through the first gap, the first shielding member can separate the small dust from the flexible screen, so that the flexible screen will not be damaged due to direct contact with dust and other foreign matters during the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0032] In a possible implementation, the folding mechanism includes a first fixed frame, a second fixed frame, a first connecting piece, a second connecting piece, a first support plate, and a second support plate. The base is located between the first fixed frame and the second fixed frame. The first connecting piece movably connects the base and the first fixed frame, and the second connecting piece movably connects the base and the second fixed frame. The first support plate movably connects the first fixed frame and the first connecting piece, and the second support plate movably connects the second fixed frame and the second connecting piece. When the electronic device is in the unfolded state, part of the second part is attached between the first support plate and the second display area, part of the second part is attached between the base and the second display area, and part of the second part is attached between the second support plate and the second display area. When the electronic device is in the folded state, part of the second part is attached between the first support plate and the second display area, part of the second part is attached to the second display area, and part of the second part is attached between the second support plate and the second display area.

[0033] It can be understood that, since the first fixed frame is fixedly connected with the first shell, the second fixed frame is fixedly connected with the second shell, the first connecting piece movably connects the first fixed frame and the middle shell, and the second connecting piece movably connects the second fixed frame and the middle shell, the first shell and the second shell can be connected with each other through the first fixed frame, the first connecting piece, the second connecting piece, and the second fixed frame. In this way, when the electronic device switches from the unfolded state to the folded state, the first shell and the second shell move towards each other, the first shell can drive the first connecting piece to move relative to the middle shell through the first fixed frame, and the second shell can drive the second connecting piece to move relative to the middle shell through the second fixed frame. When the electronic device switches from the folded state to the unfolded state, the first shell and the second shell move away from each other, the first shell can drive the first connecting piece to move relative to the middle shell through the first fixed frame, and the second shell can drive the second connecting piece to move relative to the middle shell through the second fixed frame.

[0034] It can be understood that, since the first support plate is movably connected with the first fixing frame and the first connecting piece, and the second support plate is movably connected with the second fixing frame and the second connecting piece, when the electronic device switches from the unfolded state to the folded state, the first shell can also drive the first support plate to move relative to the middle shell through the first fixing frame, and the second shell can also drive the second support plate to move relative to the middle shell through the second fixing frame. In addition, when the electronic device switches from the folded state to the unfolded state, the first support plate and the second support plate can be opened relative to the middle shell.

[0035] It can be understood that, when the electronic device is in the unfolded state, the base, the first support plate and the second support plate push the second part of the first shielding member to the second display area of the flexible screen, so that the second part of the first shielding member is not prone to dislocation and shaking. When the electronic device is in the folded state, the first support plate and the second support plate push the second part of the first shielding member to the second display area of the flexible screen, so that the second part of the first shielding member is not prone to dislocation and shaking.

[0036] It can be understood that, although the second part of the first shielding member is not fixedly connected with the folding mechanism and the second display area, the folding mechanism can push the second part of the first shielding member to the second display area of the flexible screen, so that the second part of the first shielding member is not prone to dislocation and shaking, regardless of whether the electronic device is in the unfolded state or the folded state.

[0037] In a possible implementation, the first shielding member includes a hard member, and a Young's modulus Y of the hard member satisfies: 3000Mpa≤Y≤300Gpa.

[0038] It can be understood that, since the first support plate is movably connected with the first fixing frame and the first connecting piece, and the second support plate is movably connected with the second fixing frame and the second connecting piece, when the electronic device switches from the unfolded state to the folded state, the first shell can also drive the first support plate to move relative to the middle shell through the first fixing frame, and the second shell can also drive the second support plate to move relative to the middle shell through the second fixing frame. In addition, when the electronic device switches from the folded state to the unfolded state, the first support plate and the second support plate can be opened relative to the middle shell.

[0039] In a possible implementation, the hard member includes first and second faces that face in different directions, and the first face faces the flexible screen. The first shielding member includes a first smooth member, a friction coefficient of the first smooth member is smaller than a friction coefficient of the hard member, the first smooth member is fixed to the first face of the hard member, and the first smooth member is in contact with the second display area.

[0040] It can be understood that the first smooth member is in contact with the second display area of the flexible screen, that is, the first smooth member is not fixedly connected with the second display area. Since the first smooth member is not fixedly connected with the second display area, and the friction coefficient f1 of the first smooth member is small, the first smooth member is not prone to affecting the unfolding or folding of the second display area during the unfolding or folding of the electronic device.

[0041] In a possible implementation, the hard member includes different first and second faces, the first face faces the flexible screen; the first shielding member includes a second smooth member, the second smooth member has a friction coefficient less than that of the hard member, the second smooth member is fixed to the second face of the hard member, and the second smooth member is in contact with the base.

[0042] It can be understood that the second smooth member is in contact with the base, that is, the second smooth member is not fixedly connected with the base. In this way, since the second smooth member has a small friction coefficient f2, the second smooth member is not easy to affect the movement of the base in the unfolding or folding process of the electronic device.

[0043] In a possible implementation, a part of the hard member, a part of the first smooth member, and a part of the second smooth member form a shielding portion, or a part of the hard member and a part of the first smooth member form a shielding portion, a part of the hard member and a part of the second smooth member form a shielding portion, the part of the first smooth member extends out through the edge of the hard member, the part of the second smooth member extends out through the edge of the hard member, and the part of the first smooth member extending out through the edge of the hard member is fixedly connected with the part of the second smooth member extending out through the edge of the hard member to form the shielding portion; the shielding portion extends out through the edge of the second display area in a direction close to the first end block and covers at least part of the first gap.

[0044] It can be understood that the shielding portion of the first shielding member covers at least part of the first gap, which can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal part of the electronic device through the first gap, and can also make the appearance of the electronic device more consistent, so that the user is less likely to be affected by the appearance of the electronic device having a gap when using the electronic device. In addition, even if some small dust enters the internal part of the electronic device through the first gap, the first shielding member can separate the small dust from the flexible screen, so that the flexible screen will not be damaged due to direct contact with the dust and other foreign matters in the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0045] It can be understood that when the shielding portion of the first shielding member includes the hard member, the shielding portion has better hardness. In this way, when the foreign matter in the external environment of the electronic device falls on the shielding portion, the shielding portion has better hardness to bear the dust. The first shielding member has better reliability.

[0046] It can be understood that when the shielding portion of the first shielding member does not include the hard member, the shielding portion of the first shielding member is relatively thin, thereby being more conducive to the deformation of the first shielding member in the unfolding or folding process of the electronic device. In this way, the first shielding member has less influence on the folding mechanism and the flexible screen in the unfolding or folding process.

[0047] In a possible implementation, the first smooth member is further in contact with the first display area, and the first smooth member is further in contact with the third display area. The second smooth member is further in contact with the first shell, and the second smooth member is further in contact with the second shell.

[0048] It can be understood that, since the first smooth member is not fixedly connected with the first display area and the third display area, the first smooth member is less likely to affect the unfolding or folding of the first display area and the third display area during the unfolding or folding of the electronic device.

[0049] It can be understood that, since the second smooth member is not fixedly connected with the first shell and the second shell, the second smooth member is less likely to affect the unfolding or folding of the first shell and the second shell during the unfolding or folding of the electronic device.

[0050] In a possible implementation, the friction coefficient of the first smooth member is f1, and f1 satisfies: f1 ≤ 0.4.

[0051] It can be understood that, since the first smooth member is not fixedly connected with the second display area, and the friction coefficient f1 of the first smooth member is small, the first smooth member is less likely to affect the unfolding or folding of the second display area during the unfolding or folding of the electronic device.

[0052] In a possible implementation, or the friction coefficient of the second smooth member is f2, and f2 satisfies: f2 ≤ 0.4.

[0053] It can be understood that, since the second smooth member is not fixedly connected with the first shell and the second shell, and the friction coefficient f2 of the second smooth member is small, the second smooth member is less likely to affect the movement of the first shell, the base, the first support plate, the second support plate, and the second shell during the unfolding or folding of the electronic device.

[0054] In a possible implementation, the first smooth member is Mylar. It can be understood that the surface of the first smooth member made of Mylar is relatively smooth, and has good wear resistance.

[0055] In a possible implementation, the second smooth member is Mylar. It can be understood that the surface of the second smooth member made of Mylar is relatively smooth, and has good wear resistance.

[0056] In a possible implementation, the thickness of the hard member in the thickness direction of the electronic device is H, and H satisfies: 0.01 mm ≤ H ≤ 0.05 mm.

[0057] It can be understood that the thickness of the hard member is appropriate, so that the hard member can have better hardness and can be bent. In addition, the thickness of the hard member is not too thick, so as to facilitate the thin design of the electronic device.

[0058] In a possible implementation, the hard material is a steel sheet or a PET sheet. It can be understood that the shielding part of the second part has better hardness because the shielding part of the second part includes the hard material. In this way, when the foreign matter in the external environment of the electronic device falls on the shielding part of the first shielding member, the shielding part of the second part has better hardness to bear the dust. The reliability of the first shielding member is better.

[0059] In a possible implementation, the first shell includes a first bezel and a first middle plate, the first bezel is fixedly connected to the periphery of the first middle plate, a part of the first bezel is arranged opposite to the folding mechanism and is arranged at a distance from the edge of the second display area to form a second gap, and a part of the first shielding member extends to the direction close to the first bezel through the edge of the second display area and shields at least part of the second gap.

[0060] It can be understood that, on the one hand, the first shielding member shields at least part of the second gap, which can prevent the dust and other foreign matters in the external environment of the electronic device from entering the internal part of the electronic device through the second gap, and on the other hand, the appearance consistency of the electronic device is better, so that the user is less likely to be affected by the use experience of the electronic device because of the gap in the appearance of the electronic device. In addition, even if some tiny dust enters the internal part of the electronic device through the second gap, the first shielding member can separate the tiny dust from the flexible screen, so that the flexible screen will not be damaged because of direct contact with the dust and other foreign matters in the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0061] In a possible implementation, the second shell includes a second bezel and a second middle plate, the second bezel is fixedly connected to the periphery of the second middle plate, a part of the second bezel is arranged opposite to the folding mechanism and is arranged at a distance from the edge of the second display area to form a third gap, and a part of the second shielding member extends to the direction close to the second bezel through the edge of the second display area and shields at least part of the third gap.

[0062] It can be understood that, on the one hand, the first shielding member shields at least part of the second gap, which can prevent the dust and other foreign matters in the external environment of the electronic device from entering the internal part of the electronic device through the second gap, and on the other hand, the appearance consistency of the electronic device is better, so that the user is less likely to be affected by the use experience of the electronic device because of the gap in the appearance of the electronic device. In addition, even if some tiny dust enters the internal part of the electronic device through the second gap, the first shielding member can separate the tiny dust from the flexible screen, so that the flexible screen will not be damaged because of direct contact with the dust and other foreign matters in the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0063] In a possible implementation, the electronic device includes a first decoration piece, the first decoration piece is fixedly connected to the first bezel, and the first decoration piece covers at least part of the second gap.

[0064] It can be understood that, on one hand, the first decoration piece can be used to cover the edges of the first display area and the second display area of the flexible screen, thereby protecting the edges of the first display area and the second display area of the flexible screen, and further improving the service life and reliability of the flexible screen; on the other hand, the first decoration piece can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal part of the electronic device through the second gap; on the other hand, the gap on the appearance of the electronic device is covered, and the appearance of the electronic device is improved. In addition, the first decoration piece can also prevent the user from scratching the edges of the flexible screen, thereby preventing damage to the flexible screen or other components of the electronic device.

[0065] In a possible implementation, the electronic device includes a second decoration piece, the second decoration piece is fixedly connected to the second bezel, and the second decoration piece covers at least part of the third gap.

[0066] It can be understood that, the second decoration piece can be used to cover the edges of the second display area and the third display area of the flexible screen, thereby protecting the edges of the second display area and the third display area of the flexible screen, and further improving the service life and reliability of the flexible screen; on the other hand, the second decoration piece can prevent dust and other foreign matters in the external environment of the electronic device from entering the internal part of the electronic device through the third gap; on the other hand, the gap on the appearance of the electronic device is covered, and the appearance of the electronic device is improved. In addition, the second decoration piece can also prevent the user from scratching the edges of the flexible screen, thereby preventing damage to the flexible screen or other components of the electronic device.

[0067] In a possible implementation, the first end block includes a first protrusion, the first protrusion is located on a side of the second display area away from the first cover piece, the first protrusion protrudes towards the second display area, and covers at least part of the first gap.

[0068] It can be understood that, the first protrusion makes the first gap be further covered. By setting the cooperation between the first protrusion and the first cover piece, the possibility that the foreign matters in the external environment of the electronic device enter the internal part of the electronic device through the first gap is smaller. In addition, the first protrusion can also prevent the user from scratching the edges of the second display area of the flexible screen, thereby improving the service life and reliability of the flexible screen.

[0069] In a possible implementation, the middle shell includes a second end block, the second end block is protruded from one end of the base away from the first end block and protrudes towards the second display area, the second end block is arranged in a spaced manner with the edge of the second display area and forms a fourth gap; the electronic device further includes a second shielding member, the second shielding member is bendable, a part of the second shielding member is located between the base and the second display area, and another part of the second shielding member extends out of the edge of the second display area towards the second end block and covers at least part of the fourth gap.

[0070] It can be understood that, by using the second shielding member to shield at least part of the fourth gap, on one hand, the electronic device can prevent foreign matters such as dust in the external environment of the electronic device from entering the internal part of the electronic device through the fourth gap, and on the other hand, the appearance consistency of the electronic device is better, so that the user is less likely to be affected in the use experience due to the appearance of the electronic device having a gap. In addition, even if some tiny dust enters the internal part of the electronic device through the fourth gap, the second shielding member can separate the tiny dust from the flexible screen, so that the flexible screen is less likely to be damaged due to direct contact with the foreign matters such as dust in the process of pressing the flexible screen, thereby greatly improving the service life and reliability of the flexible screen.

[0071] It can be understood that, since the second shielding member is located in the internal part of the electronic device, the second shielding member will not affect the appearance of the electronic device due to external leakage. In this way, the appearance of the electronic device is more concise, and the user experience is better.

[0072] It can be understood that, on one hand, the electronic device can be thinned, on the other hand, the second shielding member is less likely to scratch the user's hand, which is beneficial to improve the user experience of the electronic device, and on the other hand, the second shielding member is located in the internal part of the electronic device, so that the second shielding member is less likely to be damaged due to environmental factors of the electronic device, and the reliability of the second shielding member is better.

Among them, "fixed connection" refers to connection with each other and the relative positional relationship after connection does not change. "Movable connection" refers to connection with each other and the relative positional relationship can change after connection. In addition, the integrated structure of two components obtained by one-piece forming process means that during the formation of one of the two components, the component is connected with the other component, and the two components do not need to be connected together by reprocessing (such as bonding, welding, buckling connection, screw connection) method. "Sliding connection" means connection with each other and relative sliding after connection. "Rotary connection" means connection with each other and relative rotation after connection. Components A and B are relatively arranged, which can be that component A projects to projection C along the target direction, component B projects to projection D along the target direction, and projection C and projection D can at least mostly overlap. In some embodiments, the mostly overlap can be any of the following cases: projection C is completely located in projection D. Or, projection D is completely located in projection C. Or, projection C and projection D intersect with each other, and the intersection area of projection C and projection D accounts for more than 50% of projection C or projection D.

For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0114] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally means that the front and rear associated objects are in an "or" relationship.

[0115] FIG. 1 is a structural schematic diagram of an electronic device 100 in a flat state according to an embodiment of the present application. FIG. 2 is a partial cross-sectional schematic diagram of the electronic device 100 shown in FIG. 1 along line A-A according to an embodiment. FIG. 3 is a structural schematic diagram of the electronic device 100 in a folded state according to an embodiment of the present application. FIG. 4 is a partial cross-sectional schematic diagram of the electronic device 100 shown in FIG. 3 along line B-B according to an embodiment.

[0116] As shown in FIGS. 1-4, the present application provides a foldable electronic device 100. The foldable electronic device 100 can be a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted device, or a wearable device (such as a smart bracelet), etc. The embodiments of the present application take the mobile phone as an example for detailed description.

[0117] For the convenience of description, the thickness direction of the electronic device 100 is defined as the Z-axis direction, the extension direction of the rotation axis of the electronic device 100 is the Y-axis direction, that is, the width direction of the electronic device 100 is the Y-axis direction. The direction perpendicular to the Y-axis direction and the Z-axis direction is the X-axis direction, that is, the length direction of the electronic device 100 is the X-axis. It can be understood that the coordinate system of the electronic device 100 can also be flexibly set according to specific needs.

[0118] It can be understood that in the present embodiment, the direction of the rotation axis of the electronic device 100 is the Y-axis direction, that is, the electronic device 100 can be relatively unfolded or folded along the Y-axis direction. In this way, when the electronic device 100 is in a folded state, the size of the electronic device 100 in the X-axis direction becomes smaller. The present embodiment takes the direction of the rotation axis of the electronic device 100 as the Y-axis direction as an example for description, at this time, the electronic device 100 can be folded left and right, and the folding and unfolding of the electronic device 100 affects the length dimension of the electronic device 100. In some other embodiments, the rotation axis of the electronic device 100 can also be the X-axis direction, that is, the electronic device 100 can be relatively unfolded or folded along the X-axis direction. At this time, the electronic device 100 can be folded up and down, and the folding and unfolding of the electronic device 100 affects the width dimension of the electronic device 100.

[0119] FIG. 5 is a partial exploded view of the electronic device 100 shown in FIG. 1 according to an embodiment. FIG. 6 is a partial exploded schematic diagram of the electronic device 100 shown in FIG. 5 according to an embodiment.

[0120] As shown in FIGS. 5 and 6, the electronic device 100 includes a first housing 1 (may also be referred to as a first middle frame), a second housing 2 (may also be referred to as a second middle frame), a folding mechanism 3 (may also be referred to as a rotating shaft assembly), a flexible screen 4 (may also be referred to as a screen module), a first shielding member 5, and a second shielding member 6. In other embodiments, the electronic device 100 can include fewer or more structures. For example, when the electronic device 100 includes fewer structures, the electronic device 100 can not include the second shielding member 6. When the electronic device 100 includes more structures, the electronic device 100 can further include a camera module (not shown in the drawings).

[0121] Exemplarily, the flexible screen 4 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, or a quantum dot light emitting diode (QLED) display screen, etc. Exemplarily, the thickness direction of the folding mechanism 3 can be the Z-axis direction, the length direction of the folding mechanism 3 can be the Y-axis direction, and the width direction of the folding mechanism 3 can be the X-axis direction. In other embodiments, the coordinate system of the folding mechanism 3 can also be flexibly set according to specific needs.

[0122] As shown in FIGS. 5 and 6, the folding mechanism 3 connects the first housing 1 and the second housing 2. The folding mechanism 3 is used to relatively unfold or fold the first housing 1 and the second housing 2.

[0123] As shown in FIGS. 1 and 2, when the first housing 1 and the second housing 2 are relatively unfolded to a flat state, the electronic device 100 is in the flat state, and the first housing 1 and the second housing 2 can be 180°. In other embodiments, the first housing 1 and the second housing 2 can also have a slight deviation from 180°, for example, 165°, 177°, or 185°, etc.

[0124] As shown in FIGS. 3 and 4, when the first shell 1 and the second shell 2 are relatively folded to the closed state, the electronic device 100 is in the folded state, the first shell 1 and the second shell 2 can be folded to each other, and there can be no large gap between the first shell 1 and the second shell 2. In this way, the appearance experience of the electronic device 100 is better, and the performance of waterproof, dustproof and foreign matter prevention is better. The folding of the first shell 1 and the second shell 2 includes the case where they abut against each other, and also includes the case where there is a small gap between them. When there is a small gap between the first shell 1 and the second shell 2, some foreign matters outside the electronic device 100 will not enter between the first shell 1 and the second shell 2 through the gap.

[0125] The first shell 1 and the second shell 2 can also be relatively unfolded or folded to an intermediate state, so that the electronic device 100 is in the intermediate state, and the intermediate state can be any state between the unfolded state and the folded state.

[0126] Please refer to FIG. 5, and in combination with FIGS. 1 to 4, the flexible screen 4 includes a first display area 41, a second display area 42 and a third display area 43. The second display area 42 is connected between the first display area 41 and the third display area 43. FIGS. 1, 2 and 5 all schematically distinguish the first display area 41, the second display area 42 and the third display area 43 by dashed lines. The first display area 41 of the flexible screen 4 is fixed to the first shell 1. The third display area 43 is fixed to the second shell 2. During the process of unfolding or folding the first shell 1 and the second shell 2, the first shell 1 can drive the first display area 41 to move, the second shell 2 can drive the third display area 43 to move, the first display area 41 and the third display area 43 are unfolded or folded relatively, and the second display area 42 can be deformed.

[0127] It can be understood that, since the first display area 41 is fixed to the first shell 1 and the third display area 43 is fixed to the second shell 2, when the first shell 1 and the second shell 2 are unfolded or folded relatively, the relative unfolding and folding actions between the first display area 41 and the third display area 43 can be accurately controlled, so that the folding process and movement form of the flexible screen 4 are controllable and the reliability is higher.

[0128] As shown in FIG. 1 and FIG. 2, when the electronic device 100 is in the unfolded state, the first display area 41, the second display area 42 and the third display area 43 of the flexible screen 4 can be in a flat state, i.e., the flexible screen 4 can be in an unfolded state. For example, the first display area 41, the second display area 42 and the third display area 43 of the flexible screen 4 can be 180°. In other embodiments, the first display area 41, the second display area 42 and the third display area 43 can also have a slight deviation from 180°, such as 165°, 177° or 185°, etc. At this time, the flexible screen 4 has a continuous large-area display area, i.e., the flexible screen 4 can realize large-screen display, and the user experience is better.

[0129] For example, when the electronic device 100 is in the unfolded state, at least part of the folding mechanism 3 can be used to support the second display area 42. In this way, when the second display area 42 is subjected to pressing force, extrusion force or impact force, etc., the folding mechanism 3 can be used to improve the pressure resistance and impact resistance of the second display area 42, i.e., to ensure that the second display area 42 is not prone to problems such as indentation.

[0130] As shown in FIG. 3 and FIG. 4, when the electronic device 100 is in the folded state, the flexible screen 4 is in a folded state. For example, the first display area 41 and the third display area 43 of the flexible screen 4 are close to each other. The second display area 42 is in a bent state. At this time, the flexible screen 4 can be roughly in the shape of a "water droplet". In addition, the flexible screen 4 is located in the space surrounded by the first shell 1, the folding mechanism 3 and the second shell 2. The first display area 41 and the third display area 43 are located between the first shell 1 and the second shell 2. At this time, the planar size of the electronic device 100 is small (has a small width size), which is convenient for users to carry and store.

[0131] FIG. 7 is a partially exploded schematic view of the folding mechanism 3 in an embodiment shown in FIG. 6. FIG. 8 is a partially structural schematic view of the folding mechanism 3 in another angle in an embodiment shown in FIG. 6. FIG. 9 is a partially structural schematic view of the electronic device 100 in an embodiment shown in FIG. 3. The view angle of FIG. 8 can be the schematic view of FIG. 6 after being flipped by a certain angle in the clockwise direction.

[0132] As shown in FIG. 7 to FIG. 9, the folding mechanism 3 includes a middle shell 31, a first connecting assembly 32 and a second connecting assembly 33. The middle shell 31 can be located between the first connecting assembly 32 and the second connecting assembly 33. The first connecting assembly 32 and the second connecting assembly 33 can each movably connect the middle shell 31. For example, the length extension direction of the middle shell 31 can be the Y-axis direction. It can be understood that FIG. 7 and the relevant drawings below only schematically show some components included in the folding mechanism 3, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG. 7 and the drawings below.

[0133] Referring to FIGS. 7-9, in combination with FIGS. 5 and 6, the first connecting assembly 32 also connects the first housing 1. The second connecting assembly 33 also connects the second housing 2. It can be understood that through the cooperation of the first connecting assembly 32 and the second connecting assembly 33, the first housing 1 and the second housing 2 can be unfolded or folded relative to the middle housing 31.

[0134] Referring to FIGS. 7 and 8, in combination with FIGS. 1 and 2, when the first housing 1 and the second housing 2 are unfolded relative to each other to the unfolded state (i.e., the electronic device 100 is in the unfolded state), the first connecting assembly 32 and the second connecting assembly 33 are unfolded relative to the middle housing 31, and the middle housing 31, the first connecting assembly 32, and the second connecting assembly 33 can form a support surface 102 for supporting the second display area 42 of the flexible screen 4, so that when the second display area 42 is touched, the second display area 42 is not easily damaged or has a dent problem due to external force touch, thereby significantly improving the reliability of the flexible screen 4.

[0135] Referring to FIG. 9, in combination with FIGS. 3 and 4, when the electronic device 100 is in the folded state, the middle housing 31 is located between the first connecting assembly 32 and the second connecting assembly 33, and the first connecting assembly 32 and the second connecting assembly 33 are close to each other, the first connecting assembly 32 and the second connecting assembly 33 are oppositely arranged, and the middle housing 31, the first connecting assembly 32, and the second connecting assembly 33 can enclose at least part of the accommodation space 101. The second display area 42 of the flexible screen 4 can be located in the accommodation space 101.

[0136] The above describes that the folding mechanism 3 includes the middle housing 31, the first connecting assembly 32, and the second connecting assembly 33, and the middle housing 31 is connected to the first housing 1 and the second housing 2 through the first connecting assembly 32 and the second connecting assembly 33, respectively. It can be understood that the specific structure of the first connecting assembly 32 and the second connecting assembly 33 has various setting modes. The specific structure of the first connecting assembly 32 and the second connecting assembly 33 is not limited in the present application. In order to more clearly show the connection mode of the folding mechanism 3, the flexible screen 4, the first housing 1, and the second housing 2, the structure of the first connecting assembly 32 and the second connecting assembly 33 will be described only schematically in the following in combination with the related drawings.

[0137] FIG. 10 is a partially exploded schematic view of the folding mechanism 3 shown in FIG. 6 in an embodiment.

[0138] Referring to FIG. 10, and in combination with FIGS. 7-9, the first connecting assembly 32 includes a first fixed frame 321, a first connecting member 322, and a first support plate 323, for example. It is understood that FIG. 10 and the following related drawings only schematically show some components included in the first connecting assembly 32, and the actual shape, actual size, actual position, and actual structure of these components are not limited by FIG. 10 and the following related drawings.

[0139] The first connecting member 322 is movably connected to the middle shell 31 and the first fixed frame 321, for example. The first support plate 323 is movably connected to the first fixed frame 321 and the first connecting member 322.

[0140] In an embodiment, the first connecting member 322 is rotatably connected to the middle shell 31 and slidably connected to the first fixed frame 321. The first support plate 323 is rotatably connected to the first fixed frame 321 and rotatably connected to the first connecting member 322 by a pin shaft or the like. In other embodiments, the specific connection manner of the first connecting member 322 to the first fixed frame 321 and the middle shell 31, and the specific connection manner of the first support plate 323 to the first fixed frame 321 and the first connecting member 322 are not specifically limited in the present embodiment.

[0141] Referring to FIG. 10, and in combination with FIGS. 7-9, the second connecting assembly 33 includes a second fixed frame 331, a second connecting member 332, and a second support plate 333, for example. The second connecting member 332 is movably connected to the middle shell 31 and the second fixed frame 331. The second support plate 333 is movably connected to the second fixed frame 331 and the second connecting member 332. It is understood that the second connecting assembly 33 and the first connecting assembly 32 can be similar or identical structure, symmetrical or partially symmetrical structure, or different structure. In the present embodiment, the second connecting assembly 33 and the first connecting assembly 32 are similar structure, and the basic design of the component structure of the second connecting assembly 33, the connection relationship design between the components, and the connection relationship design of the components to other structures outside the assembly can be referred to the related solutions of the first connecting assembly 32. For example, the second connecting member 332 can be rotatably connected to the middle shell 31 and slidably connected to the second fixed frame 331. The second support plate 333 can be rotatably connected to the second fixed frame 331 and rotatably connected to the second connecting member 332 by a pin shaft or the like. Meanwhile, the second connecting assembly 33 and the first connecting assembly 32 are allowed to be slightly different in the detailed structure or position arrangement of the components. Details are not described here.

[0142] Referring to FIGS. 7-10, and in combination with FIGS. 5 and 6, the first fixed frame 321 can be fixedly connected to the first housing 1. The second fixed frame 331 can be fixedly connected to the second housing 2. It can be understood that the fixed connection manner of the first fixed frame 321 to the first housing 1 and the fixed connection manner of the second fixed frame 331 to the second housing 2 are not specifically limited by the present application, for example, can be fixedly connected by using fasteners (screws, pins, etc.), buckling connection or adhesion, etc.

[0143] It can be understood that, due to the fixed connection of the first fixed frame 321 to the first housing 1 and the fixed connection of the second fixed frame 331 to the second housing 2, the first fixed frame 321 and the second fixed frame 331 are movably connected to the middle housing 31 by the first connecting piece 322 and the second connecting piece 332, so that the first housing 1 and the second housing 2 can be connected to each other through the first fixed frame 321, the first connecting piece 322, the second connecting piece 332 and the second fixed frame 331. In this way, when the electronic device 100 switches from the unfolded state to the folded state, the first housing 1 and the second housing 2 move towards each other, the first housing 1 can drive the first connecting piece 322 to move relative to the middle housing 31 through the first fixed frame 321, and the second housing 2 can drive the second connecting piece 332 to move relative to the middle housing 31 through the second fixed frame 331. When the electronic device 100 switches from the folded state to the unfolded state, the first housing 1 and the second housing 2 move away from each other, the first housing 1 can drive the first connecting piece 322 to move relative to the middle housing 31 through the first fixed frame 321, and the second housing 2 can drive the second connecting piece 332 to move relative to the middle housing 31 through the second fixed frame 331.

[0144] It can be understood that, due to the fixed connection of the first fixed frame 321 to the first housing 1 and the fixed connection of the second fixed frame 331 to the second housing 2, the first fixed frame 321 and the second fixed frame 331 are movably connected to the middle housing 31 by the first connecting piece 322 and the second connecting piece 332, so that the first housing 1 and the second housing 2 can be connected to each other through the first fixed frame 321, the first connecting piece 322, the second connecting piece 332 and the second fixed frame 331. In this way, when the electronic device 100 switches from the unfolded state to the folded state, the first housing 1 and the second housing 2 move towards each other, the first housing 1 can drive the first connecting piece 322 to move relative to the middle housing 31 through the first fixed frame 321, and the second housing 2 can drive the second connecting piece 332 to move relative to the middle housing 31 through the second fixed frame 331. When the electronic device 100 switches from the folded state to the unfolded state, the first housing 1 and the second housing 2 move away from each other, the first housing 1 can drive the first connecting piece 322 to move relative to the middle housing 31 through the first fixed frame 321, and the second housing 2 can drive the second connecting piece 332 to move relative to the middle housing 31 through the second fixed frame 331.

[0145] Referring to FIGS. 7-9, and in combination with FIGS. 1 and 2, when the electronic device 100 is in the unfolded state, the middle housing 31, the first support plate 323 and the second support plate 333 can form a support surface 102. The support surface 102 can support the second display area 42 of the flexible screen 4.

[0146] Please refer to FIG. 10, and in combination with FIG. 3 and FIG. 4, when the electronic device 100 is in the folded state, the middle shell 31, the first support plate 323 and the second support plate 333 can enclose at least part of the accommodation space 101, and the second display area 42 can be located in the accommodation space 101.

[0147] The foregoing describes a mechanism of the folding mechanism 3 in combination with the relevant drawings. The following describes a structure of an embodiment of the middle shell 31 in combination with the relevant drawings.

[0148] FIG. 11 is an enlarged schematic view of an embodiment of the middle shell 31 at C shown in FIG. 10. FIG. 12 is a structural schematic view of an embodiment of the middle shell 31 at another angle shown in FIG. 10.

[0161] As shown in FIG. 16, the first shield 5 includes a first portion 55, a second portion 56, and a third portion 57. The second portion 56 is connected between the first portion 55 and the third portion 57, i.e., the third portion 57 can be located on a side of the second portion 56 away from the first portion 55.

In other embodiments, the shielding portion 562 of the second portion 56 of the first shield 5 can not protrude relative to the side surfaces of the first portion 55 and the third portion 57. In this case, the shielding portion 562 of the second portion 56 can be connected between the first portion 55 and the third portion 57.

FIG. 19 is a schematic diagram of a partial cross-section of the electronic device 100 shown in FIG. 3 according to an embodiment.

[0165] As shown in FIGS. 17 to 19, the first portion 55 of the first shield 5 can be located between the first housing 1 and the first display area 41, for example. The first portion 55 can be fixedly connected to the first housing 1. In other embodiments, the first portion 55 can be fixedly connected to the first display area 41. In other embodiments, the first portion 55 can be fixedly connected to both the first housing 1 and the first display area 41.

In addition, the shielding portion 562 of the second portion 56 of the first shield 5 can also protrude towards the first end block 312. The second portion 56 of the first shield 5 can be in contact with the base 311, the second display area 42, the first support plate 323, and the second support plate 333, i.e., the second portion 56 of the first shield 5 is not fixedly connected to the base 311, the second display area 42, the first support plate 323, and the second support plate 333.

[0167] A portion of the connecting portion 561 of the second portion 56 of the first shield 5 can be located between the base 311 and the second display area 42, a portion can be located between the first support plate 323 and the second display area 42, and a portion can be located between the second support plate 333 and the second display area 42, for example.

[0168] In other embodiments, when the folding mechanism 3 does not include the first support plate 323 and the second support plate 333, the second portion 56 of the first shield 5 can be located entirely between the base 311 and the second display area 42.

[0169] In other embodiments, when the folding mechanism 3 does not include the first support plate 323 or the second support plate 333, the second portion 56 of the first shield 5 can not be located between the first support plate 323 and the second display area 42, or can not be located between the second support plate 333 and the second display area 42.

[0170] As shown in FIGS. 17-19, the third portion 57 of the first shielding member 5 can be located between the second housing 2 and the third display area 43, for example. The third portion 57 can be in contact with the second housing 2 and the third display area 43, i.e., the third portion 57 is not fixedly connected to the second housing 2 and the third display area 43.

[0171] It can be understood that, in the present embodiment, the first portion 55 of the first shielding member 5 is fixedly connected to the first housing 1, the second portion 56 of the first shielding member 5 is not fixedly connected to the base 311, the second display area 42, the first support plate 323, and the second support plate 333, and the third portion 57 of the first shielding member 5 is not fixedly connected to the second housing 2 and the third display area 43, so that a part of the first shielding member 5 forms a fixed end and the other part forms a movable end. In this way, during unfolding or folding of the electronic device 100, the first shielding member 5 is neither prone to dislocation nor can it have sufficient deformation space to ensure that the first shielding member 5 is not prone to dislocation or breakage.

[0172] In other embodiments, the first portion 55 of the first shielding member 5 can not be fixedly connected to the first housing 1 and the first display area 41, the second portion 56 of the first shielding member 5 can not be fixedly connected to the base 311, the second display area 42, the first support plate 323, and the second support plate 333, and the third portion 57 of the first shielding member 5 can be fixedly connected to the second housing 2 and the third display area 43. The specific connection manner is not limited herein.

[0173] In other embodiments, the connection relationship between the first shielding member 5 and the first housing 1, the second housing 2, and the folding mechanism 3 is not limited herein.

[0174] As shown in FIG. 18, when the electronic device 100 is in the unfolded state, the first portion 55, the second portion 56, and the third portion 57 of the first shielding member 5 are in a flat plate shape, the first portion 55 is attached between the first housing 1 and the first display area 41, the third portion 57 is attached between the second housing 2 and the third display area 43, and a part of the second portion 56 is attached between the folding mechanism 3 and the second display area 42.

[0175] For example, when the electronic device 100 is in the unfolded state, a part of the second portion 56 is attached between the first support plate 323 and the second display area 42, a part is attached between the base 311 and the second display area 42, and a part is attached between the second support plate 333 and the second display area 42.

[0176] Exemplarily, when the electronic device 100 is in the unfolded state, the base 311, the first support plate 323 and the second support plate 333 push the second part 56 of the first shielding piece 5 to the second display area 42 of the flexible screen 4, so that the second part 56 of the first shielding piece 5 is not prone to dislocation and shaking.

[0177] As shown in FIG. 19, exemplarily, when the electronic device 100 is in the folded state, the first shielding piece 5 can be bent, the second part 56 is bent, the first part 55 is arranged opposite to the third part 57, the first part 55 is attached between the first housing 1 and the first display area 41, the third part 57 is attached between the second housing 2 and the third display area 43, and a part of the second part 56 is attached between the folding mechanism 3 and the second display area 42.

[0178] Exemplarily, when the electronic device 100 is in the folded state, a part of the second part 56 is attached between the first support plate 323 and the second display area 42, a part of the second part 56 is attached to the second display area 42, and a part of the second part 56 is attached between the second support plate 333 and the second display area 42.

[0179] Exemplarily, when the electronic device 100 is in the folded state, the first support plate 323 and the second support plate 333 push the second part 56 of the first shielding piece 5 to the second display area 42 of the flexible screen 4, so that the second part 56 of the first shielding piece 5 is not prone to dislocation and shaking.

[0180] It can be understood that although the second part 56 of the first shielding piece 5 is not fixedly connected with the folding mechanism 3 and the second display area 42, the folding mechanism 3 can push the second part 56 of the first shielding piece 5 to the second display area 42 of the flexible screen 4, so that the second part 56 of the first shielding piece 5 is not prone to dislocation and shaking, no matter whether the electronic device 100 is in the unfolded state or the folded state.

[0181] It can be understood that although the first part 55 of the first shielding piece 5 is not connected with the first housing 1, the first housing 1 can push the first part 55 of the first shielding piece 5 to the first display area 41 of the flexible screen 4, so that the first part 55 of the first shielding piece 5 is not prone to dislocation and shaking, no matter whether the electronic device 100 is in the unfolded state or the folded state.

[0182] It can be understood that although the third part 57 of the first shielding piece 5 is not connected with the second housing 2, the second housing 2 can push the third part 57 of the first shielding piece 5 to the third display area 43 of the flexible screen 4, so that the third part 57 of the first shielding piece 5 is not prone to dislocation and shaking, no matter whether the electronic device 100 is in the unfolded state or the folded state.

[0183] FIG. 20 is a schematic diagram of a partial structure of the electronic device 100 shown in FIG. 1 in one embodiment. FIG. 21 is a schematic diagram of a partial structure of the electronic device 100 shown in FIG. 20 in another angle in one embodiment. FIG. 22 is a schematic diagram of a partial cross-section of the electronic device 100 shown in FIG. 20 at line G-G in one embodiment. FIG. 23 is a schematic diagram of a partial cross-section of the electronic device 100 shown in FIG. 3 at line H-H in one embodiment. It can be understood that the view of FIG. 21 is the view of FIG. 20 rotated clockwise by an angle in the X-Y plane. The flexible screen 4 in FIG. 20 is hidden in FIG. 21, and the edge of the flexible screen 4 is only schematically shown by the dashed line in FIG. 21.

[0184] As shown in FIGS. 20-23, the shielding portion 562 of the second portion 56 of the first shielding member 5 can extend towards the first end block 312 through the edge of the second display area 42 and shield at least part of the first gap 103, for example.

[0185] It can be understood that the first shielding member 5 shields at least part of the first gap 103 in the present embodiment, which can prevent foreign matters such as dust in the external environment of the electronic device 100 from entering the internal of the electronic device 100 through the first gap 103, and can also make the appearance of the electronic device 100 more consistent, so that the user is less likely to be affected by the appearance of the electronic device 100 having a gap when using the electronic device 100. In addition, even if some tiny dust enters the internal of the electronic device 100 through the first gap 103, the first shielding member 5 can separate the tiny dust from the flexible screen 4, so that the flexible screen 4 will not be damaged by directly contacting with the foreign matters such as dust during the user pressing the flexible screen 4, thereby greatly improving the service life and reliability of the flexible screen 4.

[0186] It can be understood that the first shielding member 5 is located in the internal of the electronic device 100, and will not affect the appearance of the electronic device 100 by leaking out of the external of the electronic device 100. In this way, the appearance of the electronic device 100 is more simple, and the user experience is better.

[0187] In an embodiment, the first gap 103 is shielded by filling a rubber block (not shown in the drawings) in the first gap 103. However, since the thickness of the rubber block needs to be set thick to effectively shield the first gap 103, the rubber block greatly increases the thickness of the electronic device 100, which is not conducive to the thinness of the electronic device 100. In addition, since the thickness of the rubber block needs to be set thick, the rubber block is easy to scratch the user's hand when the user uses the electronic device 100, which is not conducive to improving the user experience of the electronic device 100. In addition, since the rubber block is easy to age, the reliability of the rubber block is poor. In the present embodiment, by arranging a part of the first shielding member 5 between the base 311 and the second display area 42, a part of the edge of the second display area 42 extends towards the first end block 312, and at least part of the first gap 103 is shielded, thereby solving the problem of shielding the first gap 103 by the rubber block. In other words, the technical solution of the present embodiment can no longer use the rubber block to shield the first gap 103. At this time, on the one hand, the electronic device 100 can be thinned, on the other hand, the first shielding member 5 is not easy to scratch the user's hand, which is conducive to improving the user experience of the electronic device 100, and on the other hand, the first shielding member 5 is located inside the electronic device 100, the first shielding member 5 is not easy to be damaged by the environmental factors of the electronic device 100, and the reliability of the first shielding member 5 is better.

[0188] Hereinafter, how the first shielding member 5 shields the external dust of the electronic device 100 in the unfolded state and the folded state of the electronic device 100 will be introduced.

[0189] Fig. 22 shows only schematically the path a and path b of the foreign matter in the external environment of the electronic device 100 approaching the electronic device 100 by dotted lines with arrows. It can be understood that when the electronic device 100 is in the unfolded state, if the foreign matter in the external environment of the electronic device 100 approaches the electronic device 100, the foreign matter in the external environment of the electronic device 100 will fall on the part of the first shielding member 5 extending beyond the edge of the second display area 42 along the path a. In this way, the first shielding member 5 can be used to prevent the foreign matter in the external environment of the electronic device 100 from entering the inside of the electronic device 100, that is, dust cannot enter the inside of the electronic device 100. As for some tiny dust, if the tiny dust enters the electronic device 100 through the gap between the edge of the first shielding member 5 and the first side surface 3121 of the first end block 312. In one case, when the first shielding member 5 is in contact with the base 311, the first shielding member 5 can isolate the tiny dust in the gap between the edge of the first shielding member 5 and the first side surface 3121 of the first end block 312, so that the tiny dust cannot enter the inside of the electronic device 100. In another case, when the first shielding member 5 is in contact with the base 311, the tiny dust falls between the first shielding member 5 and the base 311. At this time, although the tiny dust can enter the inside of the electronic device 100 along the path b, the first shielding member 5 can still isolate the tiny dust to avoid the tiny dust directly contacting the second display area 42 of the flexible screen 4. In this way, when the user uses the electronic device 100, the user presses the flexible screen 4, and because the first shielding member 5 can isolate the dust and other foreign matters from the flexible screen 4, the flexible screen 4 will not be damaged due to direct contact with the dust and other foreign matters, thereby improving the service life and reliability of the flexible screen 4.

[0190] Fig. 23 schematically shows the paths c and d of the foreign matter in the external environment of the electronic device 100 approaching the electronic device 100 by means of dashed lines with arrows. It can be understood that when the electronic device 100 is in the folded state, if the foreign matter in the external environment of the electronic device 100 approaches the electronic device 100, the foreign matter in the external environment of the electronic device 100 will fall on the part of the first shielding member 5 extending beyond the edge of the second display area 42 along the path c. In this way, the first shielding member 5 can be used to prevent the foreign matter in the external environment of the electronic device 100 from entering the inside of the electronic device 100, i.e., dust cannot enter the inside of the electronic device 100. As for some tiny dust, if the tiny dust enters the electronic device 100 through the gap between the edge of the first shielding member 5 and the first side surface 3121 of the first end block 312, in one case, when the first shielding member 5 is in contact with the base 311, the first shielding member 5 can isolate the tiny dust in the gap between the edge of the first shielding member 5 and the first side surface 3121 of the first end block 312, so that the tiny dust cannot enter the inside of the electronic device 100. In another case, when the first shielding member 5 is in contact with the base 311, the tiny dust falls between the first shielding member 5 and the base 311. At this time, although the tiny dust can enter the inside of the electronic device 100 along the path d, the first shielding member 5 can still isolate the tiny dust to avoid the tiny dust directly contacting the second display area 42 of the flexible screen 4. In this way, when the user uses the electronic device 100, the user presses the flexible screen 4, and since the first shielding member 5 can isolate the dust and other foreign matters from the flexible screen 4, the flexible screen 4 will not be damaged due to direct contact with the dust and other foreign matters, thereby improving the service life and reliability of the flexible screen 4.

[0191] As shown in Figs. 22 and 23, for example, in the length extension direction of the middle shell 31, i.e., in the Y-axis direction, the shortest distance L between the edge of the second part 56 of the first shielding member 5 close to the first end block 312 and the side surface (i.e., the first side surface 3121) of the first end block 312 close to the first shielding member 5 satisfies: L≤0.2 mm (millimeter), for example, L can be equal to 0.03 mm, 0.05 mm, 0.089 mm, 0.1 mm, 0.18 mm or 0.2 mm, etc. In this way, the first shielding member 5 can better shield the first gap 103, and the foreign matter in the external environment of the electronic device 100 is less likely to enter the inside of the electronic device 100 through the first gap 103.

[0192] In other embodiments, the value range of L is not specifically limited.

[0193] As shown in FIG. 22 and FIG. 23, exemplarily, the first protrusion 3123 of the first end block 312 can be located at a side of the second display area 42 away from the first shielding member 5, and the first protrusion 3123 can protrude towards the second display area 42 and cover at least part of the first gap 103.

[0194] Exemplarily, the first shielding member 5 can be located between the first protrusion 3123 and the base 311, and at least part of the first shielding member 5 can overlap at least part of the first protrusion 3123 in the Z-axis direction.

[0195] It can be understood that the first protrusion 3123 further shields the first gap 103. By setting the first protrusion 3123 and the first shielding member 5 in cooperation, the possibility of foreign matter in the external environment of the electronic device 100 entering the internal of the electronic device 100 through the first gap 103 is smaller.

[0196] In addition, the first protrusion 3123 can also prevent the user from scratching the edge of the second display area 42 of the flexible screen 4, thereby improving the service life and reliability of the flexible screen 4.

[0197] FIG. 24 is a partial structure schematic diagram of the electronic device 100 shown in FIG. 17 in an embodiment.

[0198] As shown in FIG. 24, exemplarily, in the Y-axis direction, the first portion 55 and the frame portion of the first housing 1 are spaced apart and can enclose a first avoiding space 1041. It can be understood that the first avoiding space 1041 can be used to arrange components (not shown in the drawings) of the electronic device 100, such as a position sensor or a flexible screen 4 wire.

[0199] It can be understood that the first avoiding space 1041 can provide arrangement space for the components of the electronic device 100, and can improve the space utilization of the electronic device 100 in the thickness direction.

[0200] As shown in FIG. 24, exemplarily, in the Y-axis direction, the third portion 57 and the frame portion of the second housing 2 are spaced apart and can enclose a second avoiding space 1042. It can be understood that the second avoiding space 1042 can also be used to arrange components of the electronic device 100. For example, a position sensor or a flexible screen 4 wire.

[0201] It can be understood that the second avoiding space 1042 can provide arrangement space for the components of the electronic device 100, and can improve the space utilization of the electronic device 100 in the thickness direction.

[0202] It can be understood that the foregoing specifically describes the position and role of the first shielding member 5 in the electronic device 100 in combination with the relevant drawings, and the following specifically describes several embodiments of the specific structure of the first shielding member 5 in combination with the relevant drawings.

[0203] FIG. 25A is an exploded schematic view of the first shielding member 5 shown in FIG. 5 in an embodiment.

[0204] As shown in FIG. 25A, the first shielding member 5 includes, for example, a hard member 51, a first smooth member 52, a second smooth member 53, and an adhesive 54. The friction coefficient of the first smooth member 52 is less than the friction coefficient of the hard member 51. The friction coefficient of the second smooth member 53 is less than the friction coefficient of the hard member 51. In other embodiments, the first shielding member 5 can include more or fewer structures. For example, when the first shielding member 5 includes fewer structures, the first shielding member 5 can not include the first smooth member 52 and / or the second smooth member 53 and / or the adhesive 54.

[0205] For example, the Young's modulus Y of the hard member 51 satisfies 3000 MPa≤Y≤300 Gpa. For example, Y can be 3000 MPa, 4000 MPa, 1 Gpa, 20 Gpa, 100 Gpa, or 200 Gpa, etc. It can be understood that the hardness of the hard member 51 is preferably high, and the first shielding member 5 can have high reliability.

[0206] For example, the hard member 51 can be a steel sheet or a PET sheet (polyethylene terephthalate). When the hard member 51 is a steel sheet, the first shielding member 5 can be a sliding steel sheet assembly.

[0207] For example, the thickness of the hard member 51 in the Z-axis direction is H, and H satisfies 0.01 mm≤H≤0.05 mm, for example, H can be 0.01 mm, 0.02 mm, 0.038 mm, 0.045 mm, 0.049 mm, or 0.05 mm, etc.

[0208] It can be understood that by setting the thickness H of the hard member 51 in the Z-axis direction to satisfy 0.01 mm≤H≤0.05 mm, the thickness of the hard member 51 is appropriate, so that the hard member 51 has good hardness and can be bent. In addition, the thickness of the hard member 51 in the embodiment is not too thick, which is beneficial to the thinness of the electronic device 100.

[0209] In other embodiments, the thickness H of the hard member 51 in the Z-axis direction is not specifically limited.

[0210] Exemplarily, the first smooth member 52 can be made of Mylar (high-performance polymer material). The material of the Mylar can be Teflon or PET. It can be understood that the surface of the first smooth member 52 made of Mylar is relatively smooth and has good wear resistance. In other embodiments, the first smooth member 52 can also be made of other materials.

[0211] Exemplarily, the friction coefficient of the first smooth member 52 is f1, which can satisfy: f1≤0.4. In other embodiments, the friction coefficient f1 of the first smooth member 52 can also satisfy other ranges.

[0212] Exemplarily, the material of the second smooth member 53 can be Mylar. The material of the Mylar can be Teflon or PET. It can be understood that the surface of the second smooth member 53 made of Mylar is relatively smooth and has good wear resistance. In other embodiments, the second smooth member 53 can also be made of other materials.

[0213] Exemplarily, the friction coefficient of the second smooth member 53 is f2, which can satisfy: f2≤0.4. In other embodiments, the friction coefficient f2 of the second smooth member 53 can also satisfy other ranges.

[0214] It can be understood that the friction coefficient f1 of the first smooth member 52 can be less than, equal to, or greater than the friction coefficient f2 of the second smooth member 53. The specific application is not limited.

[0215] FIG. 25B is a partial cross-sectional schematic view of an embodiment of the first shielding member 5 shown in FIG. 5 at the I-I line.

[0216] Referring to FIG. 25B, and in combination with FIG. 25A, exemplarily, the hard member 51 includes different first and second faces 511 and 512.

[0217] Exemplarily, the hard member 51 can be located between the first and second smooth members 52 and 53. The first smooth member 52 can be fixedly connected with the first face 511 of the hard member 51. The second smooth member 53 can be fixedly connected with the second face 512 of the hard member 51. Exemplarily, the first and second smooth members 52 and 53 can be structures with glue, for example, the first and second smooth members 52 and 53 are made of Mylar. Exemplarily, the surfaces of the first and second smooth members 52 and 53 facing the hard member 51 can each have adhesive glue, so as to be fixedly connected with the hard member 51. In other embodiments, the first and second smooth members 52 and 53 can also be structures without glue. At this time, the first and second smooth members 52 and 53 can also be fixedly connected with the hard member 51 by glue.

[0218] Exemplarily, a part of the hard member 51 and a part of the second smooth member 53 can form the first part 55 of the first shielding member 5. A part of the hard member 51 and a part of the second smooth member 53 can form the connecting part 561 of the second part 56 of the first shielding member 5. A part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the shielding part 562 of the second part 56 of the first shielding member 5. A part of the hard member 51 and a part of the second smooth member 53 can form the third part 57 of the first shielding member 5.

[0219] In other embodiments, the specific forms of the first part 55, the second part 56 and the third part 57 of the first shielding member 5 being composed of the hard member 51, the first smooth member 52 and the second smooth member 53 are not specifically limited. For example, the second smooth member 53 can extend to the entire first face 511 of the hard member 51. At this time, a part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the first part 55 of the first shielding member 5. A part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the connecting part 561 of the second part 56 of the first shielding member 5. A part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the shielding part 562 of the second part 56 of the first shielding member 5. A part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the third part 57 of the first shielding member 5. For another example, the second smooth member 53 can not extend to the first part 55 and the third part 57 of the first shielding member 5, and so on.

[0220] FIG. 25C is a partially exploded schematic view of a part of an embodiment of the electronic device 100 shown in FIG. 17.

[0221] Referring to FIG. 25C, in combination with FIGS. 18 and 19, the hard member 51 of the first shielding member 5 can be fixedly connected with the first housing 1 through the back adhesive 54. In other embodiments, the hard member 51 of the first shielding member 5 can be fixedly connected with the first display area 41 through the back adhesive 54. In other embodiments, when the number of the back adhesive 54 is two, the hard member 51 of the first shielding member 5 can be fixedly connected with the first housing 1 through one back adhesive 54. The hard member 51 of the first shielding member 5 can be fixedly connected with the first display area 41 through the second back adhesive 54.

[0222] It can be understood that the adhesive 54 can fixedly connect the first shielding member 5 with the first housing 1, or the first shielding member 5 with the flexible screen 4, or the first shielding member 5 with the first housing 1 and the flexible screen 4, so that the first shielding member 5 is not prone to dislocation in the unfolding or folding process of the electronic device 100, so as to ensure that the first shielding member is not prone to dislocation.

[0223] Referring to FIG. 25C, in combination with FIGS. 18 and 19, it is exemplarily shown that the first smooth member 52 can be in contact with the second display area 42 of the flexible screen 4, that is, the first smooth member 52 is not fixedly connected with the second display area 42. It can be understood that, since the first smooth member 52 is not fixedly connected with the second display area 42 and the friction coefficient f1 of the first smooth member 52 is small, the first smooth member 52 is not prone to affecting the unfolding or folding of the second display area 42 in the unfolding or folding process of the electronic device 100.

[0224] In other embodiments, the first smooth member 52 can be extended to between the rigid member 51 and the first display area 41, so that the first smooth member 52 is in contact with the first display area 41. For another example, the first smooth member 52 can also be extended to between the rigid member 51 and the third display area 43, so that the first smooth member 52 is also in contact with the third display area 43.

[0225] It can be understood that, since the first smooth member 52 is not fixedly connected with the first display area 41 and the third display area 43 and the friction coefficient f1 of the first smooth member 52 is small, the first smooth member 52 is not prone to affecting the unfolding or folding of the first display area 41 and the third display area 43 in the unfolding or folding process of the electronic device 100.

[0226] Referring to FIG. 25C, in combination with FIGS. 18 and 19, it is exemplarily shown that a part of the second smooth member 53 can be in contact with the first housing 1, a part can be in contact with the base 311, a part can be in contact with the first support plate 323, a part can be in contact with the second support plate 333, and a part can be in contact with the second housing 2, that is, the second smooth member 53 is not fixedly connected with the first housing 1, the base 311, the first support plate 323, the second support plate 333 and the second housing 2. In this way, since the friction coefficient f2 of the second smooth member 53 is small, the second smooth member 53 is not prone to affecting the movement of the first housing 1, the base 311, the first support plate 323, the second support plate 333 and the second housing 2 in the unfolding or folding process of the electronic device 100.

[0227] It can be understood that, since the second smooth member 53 is not fixedly connected with the first shell 1 and the second shell 2, and the friction coefficient f2 of the second smooth member 53 is small, the second smooth member 53 does not easily affect the unfolding or folding of the first shell 1 and the second shell 2 during the unfolding or folding of the electronic device 100.

[0228] In other embodiments, the shape of the second smooth member 53 can be changed so that the second smooth member 53 only contacts the base 311, or the second smooth member 53 only contacts the base 311 and the first support plate 323, or the second smooth member 53 only contacts the base 311, the first support plate 323 and the second support plate 333, or the second smooth member 53 only contacts the base 311, the first support plate 323, the second support plate 333 and the first shell 1. The specific embodiments are not limited here.

[0229] FIG. 26A is a partially exploded schematic view of the electronic device 100 shown in FIG. 13 in an embodiment. FIG. 26B is an enlarged schematic view of the electronic device 100 at J in an embodiment.

[0230] As shown in FIGS. 26A and 26B, the first shell 1 includes a first frame 11 and a first middle plate 12, for example. The first frame 11 can be fixedly connected to the periphery of the first middle plate 12. The end of the first frame 11 close to the second shell 2 forms a first groove 13. At this time, the end of the first frame 11 close to the second shell 2 is stepped.

[0231] The second shell 2 includes a second frame 21 and a second middle plate 22, for example. The second frame 21 can be fixedly connected to the periphery of the second middle plate 22. The end of the second frame 21 close to the first shell 1 forms a second groove 23. The end of the second frame 21 close to the first shell 1 is stepped.

[0232] When the electronic device 100 is in the unfolded state, the folding mechanism 3 is located in the first groove 13 and the second groove 23, for example. At this time, the end of the first frame 11 close to the second shell 2 is arranged opposite to the folding mechanism 3, and the end of the second frame 21 close to the first shell 1 is arranged opposite to the folding mechanism 3.

[0233] In other embodiments, the position relationship between the folding mechanism 3 and the first shell 1 and the second shell 2 is not limited to the positions shown in FIGS. 26A and 26B. The specific embodiments are not described here again.

[0234] FIG. 27A is a partial structural schematic view of the electronic device 100 shown in FIG. 1 in an embodiment.

[0235] As shown in FIG. 27A, exemplary, a portion of the first bezel 11 can be arranged apart from the edge of the second display area 42 of the flexible screen 4 to form a second gap 105. The second gap 105 can be located at one side of the first gap 103. The second gap 105 can be communicated with the first gap 103.

[0236] As shown in FIG. 27A, exemplary, a portion of the first bezel 11 can be arranged apart from the edge of the second display area 42 of the flexible screen 4 to form a second gap 105. The second gap 105 can be located at one side of the first gap 103. The second gap 105 can be communicated with the first gap 103.

[0237] FIG. 27B is a schematic diagram of the partial structure of the electronic device 100 shown in FIG. 1 in an embodiment.

[0238] As shown in FIG. 27B, in combination with FIG. 27A, exemplary, a portion of the first shielding member 5 can extend towards the first bezel 11 through the edge of the second display area 42 and cover at least part of the second gap 105.

[0239] It can be understood that, by using the first shielding member 5 to shield at least part of the second gap 105, on one hand, the first shielding member 5 can prevent foreign matters such as dust in the external environment of the electronic device 100 from entering the internal of the electronic device 100 through the second gap 105, on the other hand, the electronic device 100 can have better appearance consistency, so that the user can not easily be affected by the appearance of the electronic device 100 having a gap when using the electronic device 100. In addition, even if some tiny dust enters the internal of the electronic device 100 through the second gap 105, the first shielding member 5 can separate the tiny dust from the flexible screen 4, so that the flexible screen 4 will not be damaged by directly contacting with the foreign matters such as dust in the process of pressing the flexible screen 4, thereby greatly improving the service life and reliability of the flexible screen 4.

[0240] As shown in FIG. 27B, in combination with FIG. 27A, exemplary, a portion of the first shielding member 5 can extend towards the first bezel 11 through the edge of the second display area 42 and cover at least part of the second gap 105.

[0241] It can be understood that the first shielding member 5 shields at least part of the third gap 106, which can prevent foreign matters such as dust in the external environment of the electronic device 100 from entering the internal of the electronic device 100 through the third gap 106, and can make the appearance of the electronic device 100 more consistent, so that the user is less likely to be affected by the appearance of the electronic device 100 having a gap when using the electronic device 100. In addition, even if some tiny dust enters the internal of the electronic device 100 through the third gap 106, the first shielding member 5 can separate the tiny dust from the flexible screen 4, so that the flexible screen 4 will not be damaged by directly contacting with the foreign matters such as dust during the user pressing the flexible screen 4, thereby greatly improving the service life and reliability of the flexible screen 4.

[0242] Fig. 28 is a partial structural schematic diagram of the electronic device 100 shown in Fig. 1 in an embodiment.

[0243] As shown in Fig. 28, the electronic device 100 can also include a first decoration member 7 (which can also be referred to as a first screen decoration member) exemplarily. The first decoration member 7 can be fixedly connected to the first frame 11 exemplarily. The first decoration member 7 can shield at least part of the second gap 105. In this way, on the one hand, the first decoration member 7 can be used to cover the edges of the first display area 41 and the second display area 42 of the flexible screen 4, thereby protecting the edges of the first display area 41 and the second display area 42 of the flexible screen 4, and further improving the service life and reliability of the flexible screen 4; on the other hand, the first decoration member 7 can prevent foreign matters such as dust in the external environment of the electronic device 100 from entering the internal of the electronic device 100 through the second gap 105. On the other hand, the gap on the appearance of the electronic device 100 is shielded, which improves the appearance of the electronic device 100. In addition, the first decoration member 7 can also prevent the user from picking the edges of the flexible screen 4, thereby preventing damage to the flexible screen 4 or other components of the electronic device 100.

[0244] The electronic device 100 can also include a second decoration member 8 (which can also be referred to as a second screen decoration member) exemplarily. The second decoration member 8 can be fixedly connected to the second frame 21. The second decoration member 8 can shield at least part of the third gap 106. The second decoration member 8 is arranged in a similar or same manner as the first decoration member 7, and details are not repeated here.

[0245] It can be understood that the second decoration piece 8 can be used to cover the edges of the second display area 42 and the edges of the third display area 43 of the flexible screen 4, so as to protect the edges of the second display area 42 and the edges of the third display area 43 of the flexible screen 4, thereby improving the service life and reliability of the flexible screen 4. On the other hand, the second decoration piece 8 can prevent foreign matters such as dust in the external environment of the electronic device 100 from entering the inside of the electronic device 100 through the third gap 106. On the other hand, the gap on the appearance of the electronic device 100 is shielded, and the appearance of the electronic device 100 is improved. In addition, the second decoration piece 8 can also prevent the user from picking the edges of the flexible screen 4, thereby preventing damage to the flexible screen 4 or other components of the electronic device 100.

[0246] The structure of the electronic device 100 in some embodiments is specifically introduced above in combination with related drawings. The structure of the electronic device 100 in some other embodiments will be introduced below in combination with related drawings. It can be understood that the related designs of the electronic device 100 shown in the foregoing can also be directly applied to the structure design of the electronic device 100 shown in the following without conflict. Among them, most of the technical contents of the electronic device 100 shown in the foregoing will not be repeated below.

[0247] FIG. 29 is an exploded schematic view of the first shielding piece 5 shown in FIG. 5 in an embodiment. FIG. 30 is a partial cross-sectional schematic view of the first shielding piece 5 shown in FIG. 29 at K-K line in an embodiment.

[0248] As shown in FIGS. 29 and 30, for example, a part of the hard piece 51, a part of the first smooth piece 52 and a part of the second smooth piece 53 can form the first part 55 of the first shielding piece 5, a part of the hard piece 51, a part of the first smooth piece 52 and a part of the second smooth piece 53 can form the second part 56 of the first shielding piece 5, and a part of the hard piece 51, a part of the first smooth piece 52 and a part of the second smooth piece 53 can form the third part 57 of the first shielding piece 5. In other words, the first part 55, the second part 56 and the third part 57 of the first shielding piece 5 all include the hard piece 51, the first smooth piece 52 and the second smooth piece 53.

[0249] As shown in FIG. 17, it can be understood that, since the first portion 55, the second portion 56 and the third portion 57 of the first shielding member 5 all include the first smooth member 52, the first smooth member 52 can extend between the hard member 51 and the first display area 41, between the hard member 51 and the second display area 42, and between the hard member 51 and the third display area 43, so that the first smooth member 52 is in contact with the first display area 41, the second display area 42 and the third display area 43. In this way, during unfolding or folding of the electronic device 100, the first smooth member 52 is less likely to affect the unfolding or folding of the first display area 41, the second display area 42 and the third display area 43.

[0250] Exemplarily, a part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the connecting portion 561 of the second portion 56. A part of the hard member 51, a part of the first smooth member 52 and a part of the second smooth member 53 can form the shielding portion 562 of the second portion 56. In other words, the connecting portion 561 and the shielding portion 562 of the second portion 56 both include the hard member 51, the first smooth member 52 and the second smooth member 53.

[0251] As shown in FIGS. 21 and 22, it can be understood that, since the shielding portion 562 of the second portion 56 includes the hard member 51, the shielding portion 562 of the second portion 56 has better hardness. In this way, when a foreign matter in the external environment of the electronic device 100 falls on the shielding portion 562 of the first shielding member 5, the shielding portion 562 of the second portion 56 has better hardness to bear the dust. The reliability of the first shielding member 5 is better.

[0252] FIG. 31 is an exploded schematic view of the first shielding member 5 shown in FIG. 5 in another embodiment. FIG. 32 is a partial cross-sectional schematic view of the first shielding member 5 shown in FIG. 31 along the line L-L in an embodiment.

[0253] As shown in FIGS. 31 and 32, exemplarily, the first shielding member 5 includes the hard member 51, the first smooth member 52 and the second smooth member 53. It can be understood that the material, the friction coefficient, the thickness and the like of the hard member 51, the first smooth member 52 and the second smooth member 53 in the present embodiment can refer to the material, the friction coefficient, the thickness and the like of the hard member 51, the first smooth member 52 and the second smooth member 53 in the foregoing. In addition, the cooperation relationship of the first shielding member 5 with other structures (for example, the first housing 1, the second housing 2 and the folding mechanism 3) can also refer to the cooperation relationship of the first shielding member 5 with other structures (for example, the first housing 1, the second housing 2 and the folding mechanism 3) in the foregoing. Details are not described here again.

[0254] As shown in FIGS. 31 and 32, exemplarily, the hard member 51 includes a first face 511 and a second face 512 facing away from each other.

[0255] Exemplarily, the hard piece 51 can be located between the first smooth piece 52 and the second smooth piece 53. The first smooth piece 52 can be fixedly connected with the first face 511 of the hard piece 51, and a part of the first smooth piece 52 can extend out of the edge of the hard piece 51. The second smooth piece 53 can be fixedly connected with the second face 512 of the hard piece 51, and a part of the second smooth piece 53 can extend out of the edge of the hard piece 51. The part of the first smooth piece 52 extending out of the edge of the hard piece 51 can be fixedly connected with the part of the second smooth piece 53 extending out of the edge of the hard piece 51 to form the shielding part 562. The shielding part 562 can be used to shield at least part of the first gap 103 (see FIG. 21 and FIG. 22).

[0256] It can be understood that at least part of the shielding part 562 of the second part 56 of the first shielding piece 5 in the foregoing can be used to form the shielding part 562. At this time, the shielding part 562 of the first shielding piece 5 in the present embodiment is different from the shielding part 562 of the first shielding piece 5 in the foregoing in that the shielding part 562 of the first shielding piece 5 in the present embodiment only includes a part of the first smooth piece 52 and a part of the second smooth piece 53, the hard piece 51 in the foregoing extends towards the first end block 312, while the hard piece 51 in the present embodiment is retracted away from the first end block 312 at the position where the hard piece 51 in the foregoing extends, and the first smooth piece 52 and the second smooth piece 53 in the present embodiment can directly contact, that is, the shielding part 562 of the first shielding piece 5 in the present embodiment does not include the hard piece 51. Therefore, the thickness of the shielding part 562 of the first shielding piece 5 in the present embodiment is thinner, thereby being more conducive to deformation of the first shielding piece 5 in the process of unfolding or folding of the electronic device 100. In this way, the first shielding piece 5 has less influence on the folding mechanism 3 and the flexible screen 4 in the process of unfolding or folding.

[0257] The foregoing introduces the cooperation relationship between the first shielding piece 5 and other components (for example, the first shell 1, the second shell 2 and the folding mechanism 3) of the folding mechanism 3 and the role of the first shielding piece 5 in combination with relevant drawings, and the following will briefly introduce the cooperation relationship between the second shielding piece 6 and other components (for example, the first shell 1, the second shell 2 and the folding mechanism 3) of the folding mechanism 3 and the role of the second shielding piece 6 in combination with relevant drawings. The same technical content as the foregoing will not be described herein again.

[0258] FIG. 33 is a partial structure schematic diagram seven of the electronic device 100 shown in FIG. 1 in an embodiment. FIG. 34 is a partial structure schematic diagram eight of the electronic device 100 shown in FIG. 1 in an embodiment.

[0259] As shown in FIGS. 33 and 34, the electronic device 100 further comprises a second shielding member 6. It can be understood that the second shielding member 6 and the first shielding member 5 can be of the same structure, symmetrical structure, partially symmetrical structure, or different structure, which is not strictly limited in the present application. Exemplarily, the second shielding member 6 and the first shielding member 5 can be of symmetrical structure. The basic design of the component structure of the second shielding member 6, the connection relationship design between the components, and the connection relationship design of the components and other structures outside the assembly (for example, the first housing 1, the second housing 2, and the folding mechanism 3, etc.) can be referred to the related solutions of the first shielding member 5, while allowing the second shielding member 6 and the first shielding member 5 to be slightly different in the detailed structure or position arrangement of the components.

[0260] As shown in FIGS. 33 and 34, exemplarily, the second end block 313 is protruded from one end of the base 311 away from the first end block 312, and protrudes towards the direction close to the second display area 42, the second end block 313 is arranged spaced apart from the edge of the second display area 42, and forms a fourth gap 107.

[0261] As shown in FIGS. 33 and 34, exemplarily, the second shielding member 6 is foldable, a part of the second shielding member 6 is located between the base 311 and the second display area 42, and a part of the second shielding member 6 extends outwards through the edge of the second display area 42 towards the direction close to the second end block 313, and covers at least part of the fourth gap 107. It can be understood that the present embodiment shields at least part of the fourth gap 107 by using the second shielding member 6, which can prevent the dust and other foreign matters in the external environment of the electronic device 100 from entering the inside of the electronic device 100 through the fourth gap 107, and can make the appearance consistency of the electronic device 100 better, so that the user is not easily affected by the appearance of the electronic device 100 having a gap when using the electronic device 100. In addition, even if some tiny dust enters the inside of the electronic device 100 through the fourth gap 107, the second shielding member 6 can separate the tiny dust from the flexible screen 4, so that the flexible screen 4 will not be damaged due to direct contact with the dust and other foreign matters in the process of pressing the flexible screen 4, thereby greatly improving the service life and reliability of the flexible screen 4.

[0262] It can be understood that since the second shielding member 6 is located inside the electronic device 100, the second shielding member 6 will not affect the appearance of the electronic device 100 due to external leakage outside the electronic device 100. In this way, the appearance of the electronic device 100 is more concise, and the user experience is better.

[0263] In one embodiment, the fourth gap 107 is shielded by filling rubber blocks in the fourth gap 107. However, since the thickness of the rubber blocks needs to be set relatively thick to effectively shield the fourth gap 107, the rubber blocks increase the thickness of the electronic device 100 to a great extent, which is not conducive to the thinness of the electronic device 100. In addition, since the thickness of the rubber blocks needs to be set relatively thick, the rubber blocks are easy to scratch the hands of the user when the user uses the electronic device 100, which is not conducive to improving the user experience of the electronic device 100. In addition, since the rubber blocks are easy to age, the reliability of the rubber blocks is poor. In the present embodiment, by locating a part of the second shielding member 6 between the base 311 and the second display area 42, and a part of the second shielding member 6 extending out of the edge of the second display area 42 towards the second end block 313 and shielding at least part of the fourth gap 107, the problems of the scheme of shielding the fourth gap 107 by the rubber blocks are solved. In other words, the technical scheme of the present embodiment can no longer use the scheme of shielding the fourth gap 107 by the rubber blocks. At this time, on the one hand, the electronic device 100 can be thinned, on the other hand, the second shielding member 6 is not easy to scratch the hands of the user, which is conducive to improving the user experience of the electronic device 100, and on the other hand, the second shielding member 6 is located inside the electronic device 100, the second shielding member 6 is not easy to be damaged by environmental factors of the electronic device 100, and the reliability of the second shielding member 6 is better.

[0264] Hereinafter, one application scenario of the first shielding member 5 is specifically introduced.

[0265] Exemplarily, the first shielding member 5 can be a sliding steel sheet assembly. The sliding steel sheet assembly can include a steel sheet, a first Mylar, a second Mylar, and an adhesive. It can be understood that the steel sheet in the present embodiment can be one embodiment of the hard piece 51 in the foregoing, the first Mylar in the present embodiment can be one embodiment of the first smooth piece 52 in the foregoing, and the second Mylar in the present embodiment can be one embodiment of the second smooth piece 53 in the foregoing.

[0266] Exemplarily, the steel sheet can be located between the first Mylar and the second Mylar. The surface of the first Mylar facing the steel sheet can include an adhesive, that is, the first Mylar itself has an adhesive. The first Mylar can be directly bonded with the steel sheet. The surface of the second Mylar facing the steel sheet can include an adhesive, that is, the second Mylar itself has an adhesive. The second Mylar can be directly bonded with the steel sheet. In this way, the first Mylar, the second Mylar and the steel sheet are not easy to slide relative to each other.

[0267] Exemplarily, a part of the steel sheet of the sliding steel sheet assembly can be fixedly connected with the first middle frame by the adhesive. In some embodiments, a part of the steel sheet of the sliding steel sheet assembly can be fixedly connected with the screen module by the adhesive. In other embodiments, a part of the steel sheet of the sliding steel sheet assembly can be fixedly connected with the first middle frame by the adhesive, and a part can be fixedly connected with the screen module by the adhesive.

[0268] Exemplarily, at least a part of the sliding steel sheet assembly can be located between the rotating shaft assembly and the screen module. When the electronic device is in the unfolded state, the screen module and the sliding steel sheet assembly are also in the unfolded state, and the rotating shaft assembly pushes a part of the sliding steel sheet assembly towards the screen module, so that the part is not prone to dislocation and shaking. When the electronic device is in the folded state, the screen module and the sliding steel sheet assembly are also in the folded state, and the rotating shaft assembly pushes a part of the sliding steel sheet assembly towards the screen module, so that the part is not prone to dislocation and shaking.

[0269] It can be understood that when the electronic device is switched from the unfolded state to the folded state, the first middle frame and the second middle frame can approach each other, the rotating shaft assembly pushes the sliding steel sheet assembly onto the screen module, the screen module and the sliding steel sheet assembly can be bent at the same time, and the screen assembly and the sliding steel sheet assembly can not slide relative to each other. When the electronic device is switched from the folded state to the unfolded state, the first middle frame and the second middle frame can be opened relative to each other, the rotating shaft assembly pushes the sliding steel sheet assembly onto the screen module, and the screen module and the sliding steel sheet assembly can be unfolded at the same time.

[0270] Exemplarily, a part of the second Mylar can be in contact with the first middle frame, a part can be in contact with the rotating shaft assembly, and a part can be in contact with the second middle frame, that is, the second Mylar is not fixedly connected with the first middle frame, the rotating shaft assembly, and the second middle frame. In this way, since the second Mylar has a small friction coefficient, the second Mylar is not prone to affecting the movement of the first middle frame, the rotating shaft assembly, and the second middle frame during the unfolding or folding of the electronic device.

[0271] Exemplarily, the rotating shaft assembly can include a main shaft, and a side surface of the main shaft can be arranged opposite to an edge of a part of the screen module to form a gap. The steel sheet located between the main shaft and the screen module can be provided with a protruding structure, and the protruding structure of the steel sheet can protrude towards the side surface of the main shaft. It can be understood that the protruding structure of the steel sheet is an embodiment of the shielding part 562 described above. The protruding structure of the steel sheet, the first Mylar and the second Mylar can shield the gap between the side surface of the main shaft and the screen module. When the electronic device is in the unfolded state, the protruding structure of the steel sheet can shield the gap to a large extent, thereby reducing the risk of sand and dust in the external environment of the electronic device entering the internal part of the electronic device through the gap. When the electronic device is in the folded state, the sliding steel sheet assembly bends along with the bending of the screen module, and the protruding structure of the steel sheet, the first Mylar and the second Mylar can shield at least part of the gap between the side surface of the main shaft and the screen module, and can also shield at least part of the gap between the first middle frame, the second middle frame and the screen module.

[0272] In an embodiment, the side surface of the main shaft can include a protruding structure, and the protruding structure of the main shaft is arranged opposite to a part of the screen module. The protruding structure of the main shaft cooperates with the sliding steel sheet assembly to shield the gap between the side surface of the main shaft and the screen module. In other embodiments, the side surface of the main shaft can also not include a protruding structure, and only the sliding steel sheet assembly can shield the gap between the side surface of the main shaft and the screen module, and the main shaft cannot shield the gap between the side surface of the main shaft and the screen module.

[0273] In an embodiment, the steel sheet can not include a protruding structure, that is, the protruding structure is recessed. The part of the first Mylar extending out of the steel sheet and the part of the second Mylar extending out of the steel sheet can be directly fixed and connected by adhesive. The first Mylar and the second Mylar jointly shield at least part of the gap between the side surface of the main shaft and the screen module.

[0274] In an embodiment, the first Mylar can extend to a larger area, and the area of the first Mylar can even extend to equal to the area of the steel sheet. In this way, the contact area between the steel sheet and the screen module can be reduced, and the steel sheet can even not contact the screen module. In this way, compared with the contact between the steel sheet and the screen module, the first Mylar will not affect the unfolding or folding of the screen module.

[0275] It can be understood that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and any combination of the features in different embodiments is also within the protection scope of the present application, that is, the above-described multiple embodiments can also be combined as needed.

[0276] It can be understood that all the above drawings are exemplarily illustrated in the application, and do not represent the actual size of the product. The size ratio relationship between the components in the drawings is not limited to the actual product of the application. The above are only part of the embodiments and implementation manners of the application, and the protection scope of the application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
