Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic products, and in particular to an electronic device. Background Art

[0002] Foldable electronic devices typically include a first housing, a second housing, and a folding mechanism connected between the first and second housings. The folding mechanism allows the first and second housings to be relatively closed or unfolded. To prevent interference or friction between the first and second housings during the process of relative closing or unfolding, which could affect the feel or cause malfunction, foldable electronic devices typically include gaps between the first and second housings and the folding mechanism, and between the first and second housings and the folding mechanism.

[0003] However, when the first and second housings are relatively closed, dust, sand, and the like can easily enter the interior of the electronic device through the gap between the first and second housings and the folding mechanism, causing damage to the electronic device. Therefore, preventing foreign matter from entering the interior of a foldable electronic device when it is in the closed state has become an urgent issue to be addressed. Utility Model Content

[0004] The present application provides an electronic device. When the electronic device is in a closed state, external dust and sand particles are not easily able to enter the interior of the electronic device through the gap between the first shell, the second shell, and the folding mechanism.

[0005] An embodiment of the present application provides an electronic device. The electronic device includes a first housing, a second housing, and a folding mechanism. The folding mechanism is connected between the first and second housings, and the first and second housings can be relatively closed or flattened by the movement of the folding mechanism. The folding mechanism includes a main shaft and a connecting assembly. The main shaft is located between the first and second housings, and the connecting assembly connects the main shaft, the first housing, and the second housing. The main shaft includes a main shaft body and a dustproof member, which is fixed to the main shaft body. When the electronic device is in a closed state, the first and second housings are arranged relative to each other, at least a portion of the main shaft body is exposed relative to the first and second housings, and at least a portion of the dustproof member covers the gap between the main shaft body and the first housing. It is understood that in traditional electronic devices, to facilitate the relative expansion and closing of the first and second housings, a gap is usually left between the first and second housings and the folding mechanism. When the first and second housings are relatively closed, a large gap exists between the folding mechanism and the first and second housings. Dust, sand, etc. from the outside of the electronic device can easily enter the interior of the electronic device through this gap, affecting the reliability of the electronic device.

[0006] To this end, in the embodiments of the present application, the folding mechanism includes a dustproof member. When the electronic device is in the closed state, at least a portion of the dustproof member can cover the gap between the main shaft body and the first housing. This prevents dust, sand, and the like from the outside of the electronic device from entering the interior of the electronic device through the gap between the main shaft body and the first housing, thereby affecting the reliability of the electronic device.

[0007] In some embodiments, the electronic device includes a first shell, a second shell and a folding mechanism, the folding mechanism is connected between the first shell and the second shell, and the first shell and the second shell can be relatively closed or flattened through the movement of the folding mechanism; the folding mechanism includes a main shaft and a connecting component, the main shaft is located between the first shell and the second shell, and the connecting component connects the main shaft, the first shell and the second shell; the electronic device also includes a dustproof part, the dustproof part is fixed to the first shell, when the electronic device is in a closed state, the first shell and the second shell are arranged opposite to each other, and the dustproof part at least partially covers the gap between the main shaft and the first shell.

[0008] It's understandable that in conventional electronic devices, a gap is typically left between the first and second housings and the folding mechanism to facilitate relative expansion and closure of the first and second housings. When the first and second housings are closed, a significant gap exists between the folding mechanism and the first and second housings. Dust, sand, and other particles from the outside of the electronic device can easily enter through this gap, affecting its reliability.

[0009] To this end, in the embodiments of the present application, a dustproof member is provided and fixed to the first housing, so that when the electronic device is in the closed state, at least a portion of the dustproof member can cover the gap between the main shaft and the first housing. In this way, dust, sand, etc. outside the electronic device are not easily able to enter the interior of the electronic device through the gap between the main shaft and the first housing, thereby affecting the reliability of the electronic device.

[0010] In some embodiments, the dustproof part includes a main body and a first extension part. The main body is fixedly connected to the main shaft body, and the first extension part extends to one side relative to the main shaft body. When the electronic device is in a closed state, the first extension part covers the gap between the main shaft body and the first shell.

[0011] In this embodiment, the dustproof member may further include a first extension portion, which can extend relative to the main shaft body in a direction closer to the first housing, thereby covering the gap between the main shaft body and the first housing. In this way, dust, sand, etc. outside the electronic device are unlikely to enter the interior of the electronic device through the gap between the main shaft body and the first housing, thereby affecting the reliability of the electronic device.

[0012] In some embodiments, the dustproof member further includes a second extension portion, which extends out from one side of the main shaft body. When the electronic device is in a closed state, the second extension portion covers the gap between the main shaft body and the second shell.

[0013] In this embodiment, the dustproof member may further include a second extension portion. When the electronic device is in a closed state, the second extension portion of the dustproof member can extend relative to the main shaft in a direction close to the second shell, thereby covering the gap between the main shaft body and the second shell. In this way, when the electronic device is in a closed state, the area of the gap of the electronic device can be further reduced. Dust, sand, etc. outside the electronic device are not likely to enter the interior of the electronic device through the gap between the main shaft body and the second shell, thereby affecting the reliability of the electronic device.

[0014] In some embodiments, the first shell includes a first inner surface, the first inner surface of the first shell faces the main shaft body, and the second shell includes a second inner surface, the second inner surface of the second shell faces the main shaft body; when the electronic device is in a closed state, the first extension portion contacts the first inner surface of the first shell.

[0015] In this embodiment, the first extension portion can completely cover the gap between the main shaft body and the first shell, thereby further improving the dust-proof effect of the main shaft and the folding mechanism.

[0016] In some embodiments, the first shell includes a first inner surface, the first inner surface of the first shell faces the main shaft body, and the second shell includes a second inner surface, the second inner surface of the second shell faces the main shaft body; when the electronic device is in a closed state, the second extension portion contacts the second inner surface of the second shell.

[0017] In this embodiment, the second extension portion can completely cover the gap between the main shaft body and the second shell, thereby further improving the dust-proof effect of the main shaft and the folding mechanism.

[0018] In some embodiments, the electronic device also includes a flexible screen, which is installed on the first shell and the second shell; when the electronic device is in the unfolded state, the first shell and the second shell are located on the same side of the flexible screen, the first shell and the second shell cover the main axis, the main body is located between the first shell and the second shell and the flexible screen, and the first extension is located between the first shell and the flexible screen.

[0019] It is understood that when the electronic device is in the unfolded state, the first shell and the second shell can cover the main shaft. In this case, the gap between the main shaft body and the first shell and the second shell is small, and dust, sand, etc. are not likely to enter the interior of the electronic device through the gap between the main shaft body and the first shell and the second shell.

[0020] In this embodiment, the dustproof member can be located inside the first and second housings. The dustproof member can be covered by the first and second housings. The first and second housings can protect the dustproof member, thereby extending its lifespan. Furthermore, when the electronic device transitions between the closed and expanded states, the dustproof member does not bend with the movement of the first and second housings. This reduces fatigue damage to the dustproof member due to bending, resulting in a longer lifespan.

[0021] In some embodiments, the main shaft includes a main shaft body and a back cover, the back cover is fixedly connected to the main shaft body and is arranged opposite to the main shaft body, at least part of the main body is located between the main shaft body and the back cover, and the main body is fixedly connected to the main shaft body and / or the back cover; the first extension portion extends from one side relative to the main shaft body and the back cover; the second extension portion extends from the other side relative to the main shaft body and the back cover.

[0022] It will be appreciated that in this embodiment, the main body can be fixed to the back cover, and then the back cover and dust guard are assembled with the main shaft. Alternatively, the main body can be fixed to the main shaft, and then the main shaft and dust guard are assembled with the back cover. This facilitates assembly of the dust guard with the main shaft. Furthermore, at least a portion of the main body can be located between the main shaft and the back cover. This provides a larger connection area between the dust guard, the main shaft, and the back cover, and provides better connection stability.

[0023] In some embodiments, the main shaft body includes a first surface and a second surface arranged opposite to each other, the back cover includes a third surface and a fourth surface arranged opposite to each other, the first surface faces the third surface, and at least a portion of the main body is located between the first surface and the third surface; the main body includes a first surface and a second surface arranged opposite to each other, the first surface faces the first surface, and the shape of at least a portion of the first surface is the same as the shape of at least a portion of the first surface, and the second surface faces the third surface, and the shape of at least a portion of the second surface is the same as the shape of at least a portion of the third surface.

[0024] In this embodiment, at least a portion of the shape of the first surface of the dust guard is identical to at least a portion of the shape of the first surface of the main shaft body, thereby improving the positioning effect of the dust guard during assembly with the main shaft body. This facilitates assembly between the dust guard and the main shaft body. At least a portion of the shape of the second surface of the dust guard is identical to at least a portion of the shape of the third surface of the back cover, thereby improving the positioning effect of the dust guard during assembly with the back cover. This facilitates assembly between the dust guard and the back cover.

[0025] In some embodiments, at least a portion of the first surface is in contact with the first side, and at least a portion of the second surface is in contact with the third side. This, on the one hand, eliminates gaps between the main body, the spindle body, and the back cover, preventing dust, sand, and the like from entering the spindle through the gaps between the main body, the spindle body, and the back cover, potentially affecting the reliability of the spindle and the folding mechanism. On the other hand, the main body, the spindle body, and the back cover can be tightly fitted together, thereby improving the stability of the connection between the main body, the spindle body, and the back cover.

[0026] In some embodiments, the main body includes a first sub-main body, a second sub-main body and a third sub-main body, the third sub-main body is connected between the first sub-main body and the second sub-main body, the first extension is fixedly connected to the first sub-main body, and is located on the side of the first sub-main body away from the third sub-main body, the second extension is fixedly connected to the second sub-main body, and is located on the side of the second sub-main body away from the third sub-main body; the first sub-main body and the second sub-main body are opposite to and spaced apart from each other, the first sub-main body, the second sub-main body and the third sub-main body jointly enclose a accommodating space, and part of the main shaft body is located in the accommodating space; the main shaft body also includes a peripheral side surface connecting the first surface and the second surface, when the electronic device is in a closed state, the first extension portion is located between the peripheral side surface and the first shell, and the second extension portion is located between the peripheral side surface and the second shell.

[0027] In this embodiment, by setting the structure of the dustproof part, part of the main shaft body can be located in the accommodating space of the dustproof part, that is, the dustproof part can surround at least part of the main shaft body, which is beneficial to improve the connection stability between the dustproof part and the main shaft body, and the dustproof part is not easy to fall off.

[0028] In some embodiments, at least a portion of a surface of the first extension facing the main shaft body mates with at least a portion of the peripheral side surface. This eliminates the gap between the first extension and the main shaft body, thereby preventing dust, sand, and the like from entering the interior of the main shaft through the gap between the first extension and the main shaft body and affecting the reliability of the main shaft and the folding mechanism.

[0029] In some embodiments, at least a portion of a surface of the second extension facing the main shaft body mates with at least a portion of the peripheral side surface. This eliminates the gap between the second extension and the main shaft body, thereby preventing dust, sand, etc. from entering the interior of the main shaft through the gap between the second extension and the main shaft body and affecting the reliability of the main shaft and the folding mechanism.

[0030] In some embodiments, the first extension portion includes a first section and a second section, the second section is connected to the first section, the first section is connected to the main body, and along the length extension direction of the main shaft body, the first section and the main body are located on the same side of the second section; when the electronic device is in a closed state, along the arrangement direction of the first shell and the second shell, at least a portion of the first section is located between the first shell and the main shaft body; along the length extension direction of the main shaft body, at least a portion of the second section is located between the first shell and the main shaft body.

[0031] It will be appreciated that in this embodiment, along the alignment direction of the first and second housings, the first section of the first extension can extend between the spindle shaft and the first housing to cover the gap between them. Along the length of the spindle shaft, the second section of the first extension can extend between the spindle shaft and the second housing to cover the gap between them. In this way, the first extension of the dustproof member can cover the gap between the spindle shaft and the first housing in at least two directions, providing a better dustproof effect.

[0032] In some embodiments, the dustproof member is a flexible member. It is understood that the dustproof member can deform when subjected to force, so that the dustproof member is less likely to interfere with or wear the main shaft body and back cover, the first housing, and the second housing during the unfolding and folding process of the electronic device.

[0033] In some embodiments, the dustproof member is fixed to the main shaft body, and the material of the dustproof member is silicone or soft rubber. It is understood that materials such as soft rubber and silicone can better conform to the main shaft body, the first shell body, and the second shell body, so that the shape of the dustproof member can better match the shape of the gap between the main shaft body and the first shell body and the second shell body. For example, the width of the dustproof member at different positions within the gap can match the width of the gap at the corresponding position, so that the dustproof member can better block the gap between the main shaft body and the first shell body and the second shell body, and achieve a better dustproof effect.

[0034] In some embodiments, the dustproof member is secured to the first inner surface of the first housing and is made of foam. As will be appreciated, the manufacturing process for foam is mature, and semi-finished foam products can be directly cut and shaped. Therefore, the foam can be tailored to the shape of the gap to be blocked. This simplifies the manufacture of the dustproof member and reduces cutting time, thereby shortening production time and improving production efficiency.

[0035] In some embodiments, the main body includes a first part, a second part and a third part, the third part is connected between the first part and the second part, the first part is connected to the first extension part, and the second part is connected to the second extension part; at least part of the third part is located between the main shaft body and the back cover, and is fixedly connected to the back cover.

[0036] In some embodiments, the first portion, the second portion, the first extension portion, and the second extension portion are all flexible portions, the third portion is made of metal, and the third portion is welded to the back cover.

[0037] In this embodiment, the first part, the second part, the first extension part and the second extension part can be deformed after being subjected to force, and are not likely to interfere with or wear the main shaft body and the back cover, the first shell and the second shell of the main shaft body. The third part can be pre-fixed to the back cover to form a whole, and then the back cover and the dustproof part can be assembled together with the main shaft body. Compared with the method of fixing the dustproof part to the back cover or the main shaft body by dispensing glue, the third part of this embodiment is fixed to the back cover by welding, and there is no need to perform a pressure holding operation, so that the assembly between the dustproof part and the back cover is more convenient and fast, and the production efficiency is higher. In addition, the third part is fixed to the back cover by welding, so that the connection between the dustproof part and the back cover is more firm, and the dustproof part is not likely to fall off.

[0038] Furthermore, when the third portion is made of materials such as steel or iron, it can have greater rigidity and be less susceptible to deformation. The dust guard can be provided with positioning structures, such as positioning posts or positioning holes, on the third portion to facilitate positioning of the dust guard with the spindle body and back cover, thereby improving the positioning accuracy of the dust guard during assembly and achieving better positioning of the dust guard.

[0039] In some embodiments, the main shaft body includes a first surface and a second surface disposed in opposite directions, the back cover includes a third surface and a fourth surface disposed in opposite directions, the first surface faces the third surface, and at least a portion of the third portion is located between the first and third surfaces; the third portion includes a fifth surface and a sixth surface disposed in opposite directions, the fifth surface faces the first surface, and at least a portion of the fifth surface has the same shape as at least a portion of the first surface, and the sixth surface faces the third surface, and at least a portion of the sixth surface has the same shape as at least a portion of the third surface. In this way, the dustproof member has a better positioning effect when assembled with the main shaft body and the back cover. The dustproof member is more convenient to assemble with the main shaft body and the back cover.

[0040] In some embodiments, the third portion is embedded in the fourth portion and the fifth portion. This can improve the connection stability between the third portion and the fourth portion and the fifth portion, and can also improve the integrity of the dustproof member and facilitate subsequent assembly of the dustproof member.

[0041] In some embodiments, the main body includes a fourth portion and a fifth portion, the fourth portion connects the first extension portion and the second extension portion, and the fifth portion is fixedly connected between the fourth portion and the back cover.

[0042] In some embodiments, the fourth portion, the first extension portion, and the second extension portion are all flexible portions, the fifth portion is made of metal, and the fifth portion is welded to the back cover.

[0043] It can be understood that in this embodiment, the fourth part, the first extension part and the second extension part can be deformed after being subjected to force, and are not prone to interference and wear between the main shaft body and the back cover, the first shell and the second shell. The fifth part can be pre-fixed to the back cover to form a whole, and then the back cover and the dustproof part can be assembled together with the main shaft body. Compared with the method of fixing the dustproof part to the back cover or the main shaft body by dispensing glue, the fifth part of this embodiment is fixed to the back cover by welding, and there is no need to perform a pressure holding operation, which makes the assembly between the dustproof part and the back cover more convenient and quick, and the production efficiency is higher. In addition, the connection between the dustproof part and the back cover is relatively firm, and the dustproof part is not easy to fall off.

[0044] In some embodiments, the fifth portion is embedded in the fourth portion. This can improve the connection stability between the fifth portion and the fourth portion, and can also improve the integrity of the dustproof member and facilitate subsequent assembly of the dustproof member.

[0045] In some embodiments, in the length extension direction of the main shaft body, the main shaft body includes a first end and a second end that are arranged in opposite directions, and the dustproof piece is fixed to the first end or the second end.

[0046] It is understood that at the locations of the first and second ends, the gaps between the spindle shaft and the first and second housings are relatively large, leading to a more serious intrusion of dust and sand, necessitating enhanced protection. Therefore, in this embodiment, the spindle dust guard can be fixed to the first or second end of the spindle shaft to enhance dust protection at the first or second end.

[0047] In some embodiments, there are at least two dustproof members, at least one of which is fixed to the first end of the spindle shaft, and at least one of which is fixed to the second end of the spindle shaft. This can improve the dustproof effect of the first and second ends, thereby further improving the dustproof effect of the electronic device. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0079] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "left", "right", "inner", "outer", "top", "side", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0080] In the embodiments of this application, the terms "first," "second," "third," "fourth," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," "fourth," etc. may explicitly or implicitly include one or more of the features.

[0081] In the embodiments of this application, "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0082] References to or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in some embodiments," "in other embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "including," "including," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0083] The term "multiple" means at least two. The terms "parallel", "perpendicular" and other definitions are all based on the current level of technology, rather than being absolutely strict definitions in a mathematical sense. A small amount of deviation is allowed, and approximately parallel, approximately perpendicular, etc. are all acceptable. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0° and 10°. For another example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80° and 100°. The term "integrally formed" means that in the process of forming one part of a structural part, the part is connected to the other part, and the two parts do not need to be connected together through further processing (such as bonding, welding, snap connection, screw connection).

[0084] It is understood that the specific embodiments described herein are only used to explain the relevant embodiments, rather than to limit the embodiments. It should also be noted that, for ease of description, only parts related to the embodiments are shown in the drawings.

[0085] It can be understood that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0086] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0087] Please refer to Figures 1A to 2 , Figure 1A is a structural diagram of an electronic device 100 provided in this embodiment when it is in an open state. Figure 1B yes Figure 1A The electronic device 100 is a partially exploded view of some embodiments. Figure 2 yes Figure 1A The electronic device 100 is shown as a schematic diagram of the structure when it is in a closed state. The electronic device 100 can be a closable electronic product such as a mobile phone, tablet computer, laptop computer, wearable device, etc. The wearable device can be a smart watch, smart bracelet, etc. The embodiment of the present application is described using the electronic device 100 as an example of a mobile phone. Of course, other types of electronic devices can also adopt similar structures, which will not be described in detail below.

[0088] In some embodiments, the electronic device 100 may include a first housing 10, a second housing 20, a folding mechanism 30, and a flexible screen 40. It is understood that Figures 1A to 2 Only some components of the electronic device 100 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figures 1A to 2 Limited.

[0089] It is understandable that the electronic device 100 may have more components, or the electronic device 100 may have fewer components, for example, the electronic device 100 may not include the flexible screen 40.

[0090] For example, the folding mechanism 30 is connected between the first shell 10 and the second shell 20, and the first shell 10 and the second shell 20 can be relatively closed or flattened by the movement of the folding mechanism 30. Figure 1A As shown, the first shell 10 and the second shell 20 can be relatively opened by the folding mechanism 30 to be in a flattened state (as shown in FIG. Figure 1A At this time, the first shell 10 and the second shell 20 are approximately 180 degrees (slight deviation is allowed, such as 165 degrees, 177 degrees or 185 degrees), that is, the first shell 10 and the second shell 20 can be on the same plane. Figure 2 As shown, the first shell 10 and the second shell 20 can also be folded relative to each other to form a closed state. In this case, the first shell 10 and the second shell 20 can be arranged relative to each other. For example, the first shell 10 and the second shell 20 can be arranged parallel to each other (allowing a slight deviation, such as 0°, 1°, or 2°). It will be understood that the first shell 10 and the second shell 20 can switch between a flat state and a closed state.

[0091] For ease of description, exemplary, definition Figure 1A The length direction of the electronic device 100 is the X-axis direction, the width direction of the electronic device 100 is the Y-axis direction, and the thickness direction of the electronic device 100 is the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. It is understood that the coordinate system of the electronic device 100 can also be flexibly set according to specific needs.

[0092] Exemplarily, the flexible screen 40 is mounted on the same side of the first shell 10 and the second shell 20. The flexible screen 40 is used to display images, text, and videos, etc. In some examples, the flexible screen 40 may also be integrated with a display function and a touch sensing function. The display function of the flexible screen 40 is used to display text, images, videos, etc., and the touch sensing function of the flexible screen 40 is used to detect the user's touch action to achieve information interaction between man and machine. Among them, the flexible screen 40 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MIL-OLED) display, a micro light-emitting diode (MIL-LED) display, a micro organic light-emitting diode (MIL-LED) display, or a quantum dot light-emitting diode (QLED) display, etc.

[0093] For example, the flexible screen 40 may include a first display area 401, a third display area 403, and a second display area 402, arranged in sequence. The portion of the flexible screen 40 corresponding to the first housing 10 constitutes the first display area 401, which is fixed to the first housing 10; the portion of the flexible screen 40 corresponding to the second housing 20 constitutes the second display area 402, which is fixed to the second housing 20; and the portion of the flexible screen 40 corresponding to the folding mechanism 30 constitutes the third display area 403. During the relative expansion or closure of the first and second housings 10, 20, the first housing 10 drives the first display area 401 to rotate, and the second housing 20 drives the second display area 402 to rotate, causing the third display area 403 to deform under the influence of the first and second housings 10, 20.

[0094] For example, when the electronic device 100 is in a flattened state, the flexible screen 40 is also in a flattened state. At this time, the first display area 401, the third display area 403, and the second display area 402 are approximately 180° (slight deviations are allowed, such as 165°, 177°, or 185°). At this time, the flexible screen 40 has a continuous large display area, which can achieve large-screen display and provide a better user experience. When the electronic device 100 is in a closed state, the flexible screen 40 is also in a closed state. At this time, the first display area 401 and the second display area 402 are arranged face to face, and the third display area 403 is deformed and bent. The flexible screen 40 folds inward, and the flexible screen 40 is accommodated on the inner side of the first shell 10, the second shell 20, and the folding mechanism 30. At this time, the size of the electronic device 100 is small, which is convenient for storage and carrying, and the flexible screen 40 is not easily damaged.

[0095] In some other embodiments, when the electronic device 100 is in a closed state, the flexible screen 40 may also be located outside the first shell 10, the second shell 20 and the folding mechanism 30, that is, the flexible screen 40 can be folded outward.

[0096] In some embodiments, the relative rotation axis of the first housing 10 and the second housing 20 of the electronic device 100 can be parallel to the Y-axis, meaning that the folding mechanism 30 can be relatively flattened or folded along the rotation axis parallel to the Y-axis. In this way, when the electronic device 100 is in a closed state, the size of the electronic device 100 in the X-axis direction is reduced, making it easier for the user to carry. This embodiment is described using the example of "the rotation axis of the electronic device 100 is parallel to the Y-axis." In this case, the electronic device 100 can be folded left and right, and the folding and flattening of the electronic device 100 affects the length of the electronic device 100. In other embodiments, the relative rotation axis of the first housing 10 and the second housing 20 can also be parallel to the X-axis, meaning that the folding mechanism 30 can be relatively flattened or folded along the rotation axis parallel to the X-axis. In this case, the electronic device 100 can be folded up and down, and the folding and flattening of the electronic device 100 affects the width of the electronic device 100.

[0097] In some embodiments, the folding mechanism 30 may include a main shaft 30A and a connecting assembly 30B. The main shaft 30A may be located between the first shell 10 and the second shell 20, and the connecting assembly 30B connects the main shaft 30A, the first shell 10, and the second shell 20. For example, the connecting assembly 30B may be mounted on the main shaft 30A, one end of the connecting assembly 30B may be connected to the first shell 10, and the other end may be connected to the second shell 20. By the connecting assembly 30B moving relative to the main shaft 30A, the first shell 10 and the second shell 20 may move relative to the main shaft 30A to achieve relative folding or unfolding between the first shell 10 and the second shell 20. For example, the connecting assembly 30B may be fixedly connected to the first shell 10 and the second shell 20 by fasteners such as screws or by clamping or bonding, but this application is not limited to this.

[0098] like Figure 1A and Figure 1B As shown, when the electronic device 100 is in the unfolded state, the first shell 10 and the second shell 20 jointly cover the main shaft 30A, and the main shaft 30A can be hidden between the flexible screen 40 and the first shell 10 and the second shell 20. Figure 2 As shown, when the electronic device 100 is in the closed state, at least a portion of the main shaft 30A can be exposed relative to the first housing 10 and the second housing 20. It is understood that the main shaft 30A can be completely exposed relative to the first housing 10 and the second housing 20. The main shaft 30A can also be partially exposed relative to the first housing 10 and the second housing 20.

[0099] It will be understood that in the embodiments of the present application, the electronic device 100 is described as having a two-fold structure, that is, the electronic device 100 includes two housings that can be bent relative to each other. In other embodiments, the electronic device 100 may also have a three-fold structure or more, that is, the electronic device 100 may include three or more housings that bend relative to each other, with any two adjacent housings connected by a folding mechanism 30. When the electronic device 100 has a three-fold structure or more, the structure of the electronic device 100 can be adaptively designed by referring to the description of the two structures in this embodiment, and this application will not elaborate on this.

[0100] In traditional electronic devices, in order to facilitate the relative expansion and closing of the first and second shells, a gap is usually left between the first and second shells and the folding mechanism. When the first and second shells are relatively closed, there is a large gap between the folding mechanism and the first and second shells. Dust, sand, etc. on the outside of the electronic device can easily enter the interior of the electronic device through this gap and reach the bottom of the flexible screen. The accumulation of foreign matter such as dust and sand under the flexible screen can easily cause the flexible screen to fail and affect its reliability.

[0101] In particular, along the longitudinal extension direction of the main shaft, the gaps between the two opposing ends of the main shaft and the first and second shells are relatively large, resulting in a serious problem of dust intrusion, which requires special protection. To this end, the present application provides a folding mechanism 30, so that when the first and second shells 10, 20 are relatively closed, the gaps between the first and second shells 10, 20 and the opposing ends of the main shaft 30A are reduced or even eliminated, thereby easily preventing dust, sand, etc. from entering the interior of the electronic device 100 through these gaps.

[0102] Please refer to Figures 3 to 5 , Figure 3 yes Figure 2 The schematic diagram of the partial structure of the main shaft 30A in some embodiments is shown. Figure 4 yes Figure 3 The schematic structural diagram of the main shaft 30A shown in FIG. Figure 5 yes Figure 3 The spindle 30A is shown in a partially exploded view in some embodiments. Figure 3 FIG. 3 shows a schematic diagram of a portion of the structure of the main shaft 30A in the dotted box. It can be understood that Figure 3 The diagram mainly shows a partial structure diagram of one end of the main shaft 30A in its longitudinal direction (ie, the Y-axis direction). The structure of the other end of the main shaft 30A in the Y-axis direction is similar to that of the main shaft 30A. Figure 3 The structures shown can be the same or similar structures, symmetrical or partially symmetrical structures. The basic design of the structure at the other end of the main shaft 30A in the Y-axis direction, the connection relationship design between the components, and the connection relationship design between the components and other structures outside the assembly can all be referred to. Figure 3 At the same time, the structure of the other end of the main shaft 30A in the Y-axis direction is allowed to be Figure 3 The structures shown are slightly different in the detailed structure or position arrangement of the components, and the details will not be repeated here.

[0103] In some embodiments, the spindle 30A may include a spindle body 31 and a dustproof member 32. It is understood that, Figures 3 to 5 Only some of the components of the main shaft 30A are shown schematically, and the actual shape, size, position and configuration of these components are not affected by the present invention. Figures 3 to 5 The spindle 30A may have more or fewer components.

[0104] In some embodiments, the main shaft body 31 may include a main shaft body 311 and a back cover 312. The back cover 312 may be fixedly connected to the main shaft body 311 and disposed opposite to the main shaft body 311. Figure 1AAs shown, when the electronic device 100 is in the unfolded state, the first shell 10 and the second shell 20 jointly cover the back cover 312 (not shown), and the back cover 312 can be hidden between the flexible screen 40 and the first shell 10 and the second shell 20. Figure 2 As shown, when the electronic device 100 is in a closed state, the back cover 312 is exposed relative to the first shell 10 and the second shell 20. The back cover 312 forms a part of the appearance of the electronic device 100. The back cover 312 can cover the main shaft body 311 to improve the appearance consistency and aesthetics of the electronic device 100.

[0105] Please refer to Figure 5 and Figure 6 , Figure 6 yes Figure 5 The structure of the main shaft body 311 shown is a schematic diagram at another angle in some embodiments.

[0106] In some embodiments, the main shaft body 311 may include a shaft portion 3111 and an end portion 3112. Along the length of the main shaft body 31, the end portion 3112 of the main shaft body 311 may be fixedly connected to one side of the shaft portion 3111. That is, the shaft portion 3111 and the end portion 3112 may be arranged along the Y-axis direction.

[0107] In this embodiment, the shaft portion 3111 and the end portion 3112 can be an integrally molded structural member to simplify the molding process of the main shaft body 311. In other embodiments, the shaft portion 3111 and the end portion 3112 can also be formed into a single integral structural member by bonding, clamping, or the like. This application is not strictly limited to this. For example, the end portion 3112 of the main shaft body 311 can be bent relative to the shaft portion 3111. For example, the shaft portion 3111 and the end portion 3112 can be perpendicular to each other.

[0108] Exemplarily, the shaft portion 3111 of the main shaft body 311 may have a first surface 3113, a second surface 3114, and a peripheral side surface 3115 connecting the first surface 3113 and the second surface 3114 of the shaft portion 3111. The first surface 3113 and the second surface 3114 of the shaft portion 3111 may be arranged in a back-to-back manner. Exemplarily, the portion where the first surface 3113 and the peripheral side surface 3115 connect may be a curved surface. That is, a smooth transition may be provided between the first surface 3113 and the peripheral side surface 3115. In this embodiment, the first surface 3113 of the shaft portion 3111 and a portion of the peripheral side surface 3115 may together constitute the first inner surface of the main shaft body 311. The second surface 3114 of the shaft portion 3111, another portion of the peripheral side surface 3115, and a side surface of the end portion 3112 facing away from the shaft portion 3111 may together constitute the first outer surface of the main shaft body 311.

[0109] In some embodiments, the main shaft body 311 may be provided with a protrusion 3116. Exemplarily, the protrusion 3116 may be located on the shaft portion 3111 of the main shaft body 311. The protrusion 3116 may protrude from a portion of the second surface 3114 of the shaft portion 3111 in a direction away from the first surface 3113 of the shaft portion 3111. Exemplarily, the protrusion 3116 may be located approximately in the middle of the main shaft body 311. The protrusion 3116 may extend parallel to the longitudinal extension direction of the main shaft body 31.

Exemplarily, the first positioning groove 313 may be provided near the end portion 3112 of the main shaft body 311. The first positioning groove 313 may be roughly a triangular groove. The number of the first positioning grooves 313 may be one or more. When the number of the first positioning grooves 313 is multiple, at least two first positioning grooves 313 are symmetrically distributed relative to the length extension direction of the main shaft body 31 (i.e., the Y-axis direction).

[0111] In some embodiments, the main shaft body 311 may also be provided with a second positioning groove 314. For example, the second positioning groove 314 may be located on the shaft portion 3111 of the main shaft body 311. The second positioning groove 314 may be recessed from a portion of the first surface 3113 of the shaft portion 3111 toward the second surface 3114 of the shaft portion 3111.

For example, the third positioning groove 316 may be located on the shaft portion 3111 of the main shaft body 311. The third positioning groove 316 may be recessed from a portion of the first surface 3113 of the shaft portion 3111 toward the second surface 3114 of the shaft portion 3111. The third positioning groove 316 may be located on a side of the second positioning groove 314 away from the first positioning groove 313. The third positioning groove 316 may communicate with the second positioning groove 314. For example, the inner wall of the third positioning groove 316 may be connected to the side wall 3122 of the second positioning groove 314.

[0114] In some embodiments, the main shaft body 311 may further be provided with a first positioning protrusion 317.

Exemplarily, the first positioning protrusion 317 may be a circular protrusion. The number of the first positioning protrusions 317 may be one or more. When the number of the first positioning protrusions 317 is multiple, at least two first positioning protrusions 317 are symmetrically distributed relative to the length extension direction of the main shaft body 31. At least two first positioning protrusions 317 are arranged along the length extension direction of the main shaft body 31.

[0115] In some embodiments, the main shaft body 311 may further include a second positioning protrusion 318 and a third positioning protrusion 319. For example, the second positioning protrusion 318 and the third positioning protrusion 319 may be located on the shaft portion 3111 of the main shaft body 311. The second positioning protrusion 318 and the third positioning protrusion 319 may protrude from a portion of the peripheral side surface 3115 of the shaft portion 3111 in a direction away from the shaft portion 3111.

[0116] For example, the second positioning protrusion 318 and the third positioning protrusion 319 can be arranged in a back-to-back relationship. For example, the second positioning protrusion 318 and the third positioning protrusion 319 can be symmetrically distributed relative to the length of the main shaft body 31. For example, there can be one or more second positioning protrusions 318. Multiple second positioning protrusions 318 can be arranged along the length of the main shaft body 31. There can be one or more third positioning protrusions 319. Multiple third positioning protrusions 319 can be arranged along the length of the main shaft body 31.

The first extension portion 322 and the second extension portion 323 are both connected to the main portion 321 and located on the same side of the main portion 321. For example, the first extension portion 322 and the second extension portion 323 may be arranged opposite each other and spaced apart. In other embodiments, the dustproof member 32 may not include the second extension portion 323, and this application is not strictly limited to this.

The recessed area 3217 may be recessed from the first surface 3214 of the main body 321 toward the second surface 3215. Exemplarily, the recessed area 3217 may be located approximately in the middle of the third sub-body portion 3213.

[0132] In some embodiments, the main body 321 of the dustproof member 32 may further be provided with a fourth positioning protrusion 3261. Exemplarily, the fourth positioning protrusion 3261 may be located on the third sub-main body 3213 and disposed near the end of the main body 321. The fourth positioning protrusion 3261 may protrude from a portion of the first surface 3214 of the main body 321 in a direction away from the second surface 3215. Exemplarily, the fourth positioning protrusion 3261 may be roughly triangular in shape. The number of the fourth positioning protrusions 3261 may be one or more. When the number of the fourth positioning protrusions 3261 is multiple, at least two fourth positioning protrusions 3261 are symmetrically distributed relative to the length extension direction of the main shaft body 31.

[0133] In some embodiments, the main body 321 of the dustproof member 32 may further include a fifth positioning groove 3262. Exemplarily, the fifth positioning groove 3262 may be located in the third sub-body portion 3213. The fifth positioning groove 3262 may be recessed from a portion of the first surface 3214 of the main body 321 toward the second surface 3215.

The fifth positioning protrusion 3263 may protrude from a portion of the first surface 3214 of the main body 321 in a direction away from the second surface 3215. For example, the fifth positioning protrusion 3263 may be located on a side of the fifth positioning groove 3262 away from the fourth positioning protrusion 3261. The outer side surface of the fifth positioning protrusion 3263 may be connected to the inner wall of the fifth positioning groove 3262.

[0135] In some embodiments, the main body 321 of the dustproof member 32 may further be provided with a sixth positioning groove 3264. Exemplarily, the sixth positioning groove 3264 may be located in the third sub-main body 3213. The sixth positioning groove 3264 may be recessed from a portion of the first surface 3214 of the main body 321 toward the second surface 3215. Exemplarily, the sixth positioning groove 3264 may be located on a side of the fifth positioning protrusion 3263 away from the fourth positioning protrusion 3261. The sixth positioning groove 3264 may be a roughly circular groove. The number of the sixth positioning grooves 3264 may be one or more. When the number of the sixth positioning grooves 3264 is multiple, at least two of the sixth positioning grooves 3264 are symmetrically distributed relative to the length extension direction of the spindle shaft 31.

[0136] In some embodiments, the main body 321 of the dustproof member 32 may further include a sixth positioning protrusion 3265. Exemplarily, the sixth positioning protrusion 3265 may be located on the third sub-body portion 3213. The sixth positioning protrusion 3265 may be recessed from the second surface 3215 of the main body 321 in a direction away from the first surface 3214. Exemplarily, the sixth positioning protrusion 3265 may extend to the edge of the third sub-body portion 3213.

[0137] In some embodiments, a portion of the inner surface of the main body portion 321 may be recessed toward the outer surface of the main body portion 321 to form a seventh positioning groove 3267a on the inner surface of the main body portion 321 and a seventh positioning protrusion 3267b on the outer surface of the main body portion 321. For example, the seventh positioning groove 3267a and the seventh positioning protrusion 3267b may be located on the first sub-body portion 3211.

[0138] In some embodiments, a portion of the inner surface of the main body 321 can be recessed toward the outer surface of the main body 321 to form an eighth positioning groove 3268a on the inner surface of the main body 321 and an eighth positioning protrusion 3268b on the outer surface of the main body 321. Exemplarily, the eighth positioning groove 3268a and the eighth positioning protrusion 3268b can be located on the second sub-body 3212. Exemplarily, the seventh positioning groove 3267a and the eighth positioning groove 3268a can be symmetrically distributed relative to the length extension direction of the spindle shaft 31. The seventh positioning protrusion 3267b and the eighth positioning protrusion 3268b can be symmetrically distributed relative to the length extension direction of the spindle shaft 31.

[0139] In some embodiments, the first extension portion 322 can be fixedly connected to the first sub-body portion 3211 and located on a side of the first sub-body portion 3211 away from the third sub-body portion 3213. For example, the first extension portion 322 can include a first section 3221 and a second section 3222. The second section 3222 is connected to the first section 3221. The first section 3221 and the second section 3222 can be arranged along the length extension direction of the main shaft body 31. For example, Figure 8A and Figure 8B In the figures, dotted lines are used to schematically distinguish the first section 3221 and the second section 3222 of the first extension portion 322.

[0140] Illustratively, the first section 3221 can be connected to the main body 321. For example, the first section 3221 can be connected to the first sub-main body 3211 of the main body 321. Illustratively, along the length of the spindle shaft 31, the first section 3221 of the first extension portion 322 and the main body 321 can be located on the same side of the second section 3222 of the first extension portion 322. In other words, the second section 3222 of the first extension portion 322 can be located on one side of the first section 3221 of the first extension portion 322 and the main body 321.

[0141] In some embodiments, the second extension portion 323 can be fixedly connected to the second sub-body portion 3212 and located on a side of the second sub-body portion 3212 away from the third sub-body portion 3213. Exemplarily, the second extension portion 323 can include a third section 3231 and a fourth section 3232. The fourth section 3232 is connected to the third section 3231. The third section 3231 and the fourth section 3232 can be arranged along the length extension direction of the main shaft body 31 (i.e., the Y-axis direction). Exemplarily, Figure 8A and Figure 8B In the figure, dotted lines are used to schematically distinguish the third section 3231 and the fourth section 3232 of the second extension portion 323 .

[0142] For example, the third section 3231 can be connected to the main body 321. For example, the third section 3231 can be connected to the second sub-body 3212 of the main body 321. Along the length extension direction of the spindle shaft 31 (i.e., the Y-axis direction), the third section 3231 of the second extension portion 323 and the main body 321 can be located on the same side of the fourth section 3232 of the second extension portion 323. In other words, the fourth section 3232 of the second extension portion 323 can be located on one side of the third section 3231 of the second extension portion 323 and the main body 321.

[0143] For example, the first section 3221 of the first extension portion 322 may be opposite to and spaced apart from the third section 3231 of the second extension portion 323. The second section 3222 of the first extension portion 322 may be opposite to and spaced apart from the fourth section 3232 of the second extension portion 323.

[0144] In some embodiments, the dust guard 32 can be a flexible member. That is, the main body 321, the first extension 322, and the second extension 323 can deform under force. This prevents the dust guard 32 from interfering with or abrading the main shaft 311 and back cover 312 of the main shaft 31, or the first and second housings 10 and 20 during the unfolding and folding of the electronic device 100. Exemplary materials for the dust guard 32 include soft rubber, silicone, and the like. It will be appreciated that materials such as soft rubber and silicone can effectively conform to the shape of the main shaft 31, the first and second housings 10 and 20, allowing the shape of the dust guard 32 to effectively match the shape of the gap between the main shaft 31 and the first and second housings 10 and 20. For example, the width of the dust guard 32 at different locations within the gap can match the width of the gap at that location. This allows the dust guard 32 to effectively block the gap between the main shaft 31 and the first and second housings 10 and 20, achieving a better dustproof effect. In this embodiment, the dustproof part 32 can be an integrally formed structural part, that is, the main body 321, the first extension part 322 and the second extension part 323 can be integrally formed, so that the preparation process of the dustproof part 32 is relatively simple. For example, the dustproof part 32 can be made by injection molding. Figures 9A to 9C The injection mold 50 is shown. Figure 9A Schematic diagram of the structure of the injection mold 50 for making the dustproof part 32 in the embodiment of the present application. Figure 9B yes Figure 9A The partially exploded view of the injection mold 50 is shown. Figure 9C yes Figure 9A The injection mold 50 is shown as a partially exploded view at another angle.

[0145] For example, the injection mold 50 may include a female mold 51 and a male mold 52. The female mold 51 may have a recessed portion 511, and the surface of the male mold 52 may have a protruding portion 521. By injecting the injection molding material into the female mold 51 and then pressing the female mold 51 and the male mold 52 together, the injection molding material is formed by the interaction between the protruding portion 521 and the female mold 511. After cooling, the dustproof part 32 is obtained.

[0146] In other embodiments, the dustproof part 32 may also be a detachable part, and this application does not strictly limit this.

[0147] See also Figure 10 , Figure 10 yes Figure 3 The main shaft 30A shown is a partial cross-sectional structural schematic diagram taken along AA in some embodiments.

[0148] In some embodiments, a portion of the main shaft body 311 can be located in the installation space 3120 of the back cover 312. The first surface 3113 of the main shaft body 311 can be disposed toward the third surface 3121a of the back cover 312. The second surface 3114 of the main shaft body 311 can be disposed opposite to the fourth surface 3121b of the back cover 312. For example, a portion of the end portion 3112 of the main shaft body 311 can be located in the avoidance notch 3126 of the back cover 312. The end portion 3112 of the main shaft body 311 can extend outward from the back cover 312 through the avoidance notch 3126.

[0149] In some embodiments, the main body 321 of the dustproof member 32 is fixedly connected to the main shaft body 31. Exemplarily, at least a portion of the main body 321 can be located between the main shaft body 311 and the back cover 312 of the main shaft body 31, and fixedly connected to the main shaft body 311 and / or the back cover 312. For example, the main body 321 can be fixed to the back cover 312 by dispensing glue, and then the back cover 312 and the dustproof member 32 are assembled with the main shaft body 311. Alternatively, the main body 321 can be fixed to the main shaft body 311 by dispensing glue, and then the back cover 312 is assembled with the main shaft body 311 and the dustproof member 32. In this way, the assembly between the dustproof member 32 and the main shaft body 31 is facilitated.

[0150] It is understood that the main body 321 can be entirely located between the main shaft body 311 and the back cover 312 of the main shaft body 31. The main body 321 can also be partially located between the main shaft body 311 and the back cover 312 of the main shaft body 31. For example, at least a portion of the main body 321 can be located between the first surface 3113 of the main shaft body 311 and the third surface 3121a of the back cover 312. This allows the dust guard 32 to have a larger connection area with the main shaft body 311 and the back cover 312, thereby improving connection stability.

[0151] Please refer to Figure 10 and Figure 11A , Figure 11A yes Figure 3 The schematic diagram of the partial structure of the main shaft 30A in some embodiments is shown. Figure 11B yes Figure 11A The schematic diagram of the structure of the main shaft 30A shown in FIG. Figure 11A and Figure 11B It mainly shows a schematic diagram of the assembly structure of the main shaft body 311 of the main shaft shaft 31 and the dustproof part 32.

[0152] In some embodiments, at least a portion of the main shaft body 311 can be located in the accommodating space 320 of the dustproof member 32. The inner surface of the main body 321 can face the first inner surface of the main shaft body 311. It is understood that by setting the structure of the dustproof member 32, a portion of the main shaft body 311 can be located in the accommodating space 320 of the dustproof member 32, that is, the dustproof member 32 can surround at least a portion of the main shaft body 311, thereby facilitating improved connection stability between the dustproof member 32 and the main shaft body 311, and preventing the dustproof member 32 from falling off.

[0153] In some embodiments, at least a portion of the inner surface of the main body 321 has the same shape as at least a portion of the first inner surface of the main shaft body 311. Exemplarily, the first surface 3214 of the main body 321 may face the first surface 3113 of the main shaft body 311. At least a portion of the first surface 3214 has the same shape as at least a portion of the first surface 3113 of the main shaft body 311. It is understood that the main body 321 of the dustproof member 32 may be contoured to the first inner surface of the main shaft body 311 to facilitate positioning and assembly of the dustproof member 32 and the main shaft body 311. It is understood that the main body 321 may have the same shape as the first surface 3113 of the main shaft body 311 in its entirety on its first surface 3214. The main body 321 may also have the same shape as a portion of the first surface 3113 of the main shaft body 311 in its portion.

[0154] For example, the shape of the recessed area 3217 of the main body 321 can be the same as the shape of the protruding portion 3116 of the main shaft body 311. At least a portion of the protruding portion 3116 can be located within the recessed area 3217. This improves the positioning of the dust guard 32 and the main shaft body 311 during assembly, making assembly between the dust guard 32 and the main shaft body 311 more convenient.

[0155] For example, the shape of the fourth positioning protrusion 3261 of the main body 321 can be the same as the shape of the first positioning groove 313 of the main shaft body 311. At least a portion of the fourth positioning protrusion 3261 can be located within the first positioning groove 313. This improves the positioning effect when the dust guard 32 is assembled with the main shaft body 311, making assembly between the dust guard 32 and the main shaft body 311 more convenient.

[0156] For example, the fifth positioning groove 3262 of the main body 321 can be disposed opposite the second positioning groove 314. The shape of the fifth positioning groove 3262 can be the same as the shape of the second positioning groove 314 of the main shaft body 311. The bottom wall of the fifth positioning groove 3262 can cover the first through hole 315, thereby sealing the first through hole 315, thereby preventing dust and sand outside the main shaft 30A and the folding mechanism 30 from entering the interior of the main shaft 30A through the first through hole 315.

[0157] For example, the shape of the sixth positioning groove 3264 of the main body 321 can be the same as the shape of the first positioning protrusion 317 of the main shaft body 311. At least a portion of the first positioning protrusion 317 can be located within the sixth positioning groove 3264. This improves the positioning effect when the dust guard 32 is assembled with the main shaft body 311, making assembly between the dust guard 32 and the main shaft body 311 more convenient.

[0158] For example, the shape of the fifth positioning protrusion 3263 of the main body 321 can be the same as the shape of the third positioning groove 316 of the main shaft body 311. At least a portion of the fifth positioning protrusion 3263 can be located within the third positioning groove 316. This improves the positioning effect when the dust guard 32 is assembled with the main shaft body 311, making assembly between the dust guard 32 and the main shaft body 311 more convenient.

[0159] In some embodiments, at least a portion of the first surface 3214 of the main body 321 can be in contact with the first surface 3113 of the main shaft body 311. In this way, on the one hand, the gap between the main body 321 and the main shaft body 311 can be eliminated, preventing dust, sand, etc. from entering the interior of the main shaft 30A through the gap between the main body 321 and the main shaft body 311, thereby affecting the reliability of the main shaft 30A and the folding mechanism 30. On the other hand, the main body 321 and the main shaft body 311 can be tightly fitted, thereby improving the connection stability between the main body 321 and the main shaft body 311. It is understandable that the entire first surface 3214 of the main body 321 can be in contact with the first surface 3113 of the main shaft body 311. The main body 321 can also be in contact with the first surface 3113 of the main shaft body 311.

[0160] For example, the inner surface of the recessed area 3217 of the main body 321 may be aligned with the surface of the protruding portion 3116 of the main shaft body 311. The surface of the fourth positioning protrusion 3261 of the main body 321 may be aligned with the wall of the first positioning groove 313 of the main shaft body 311. The wall of the sixth positioning groove 3264 of the main body 321 may be aligned with the surface of the first positioning protrusion 317 of the main shaft body 311. The surface of the fifth positioning protrusion 3263 of the main body 321 may be aligned with the wall of the third positioning groove 316 of the main shaft body 311.

[0161] Please refer to Figure 11A and Figure 11B , Figure 11B yes Figure 11A The schematic diagram of the structure of part of the main shaft 30A shown at another angle.

[0162] In some embodiments, the shape of the seventh positioning groove 3267a of the main body 321 can be the same as the shape of the second positioning protrusion 318 of the main shaft body 311. At least a portion of the second positioning protrusion 318 can be located in the seventh positioning groove 3267a. In this way, the positioning effect of the dustproof member 32 and the main shaft body 311 during assembly is better. The assembly between the dustproof member 32 and the main shaft body 311 is more convenient. Similarly, the eighth positioning groove 3268a of the main body 321 (see Figure 8B The shape of the third positioning protrusion 319 can be the same as that of the third positioning protrusion 319 of the main shaft body 311. At least a portion of the third positioning protrusion 319 can be located within the eighth positioning groove 3268a. This improves the positioning effect when the dustproof member 32 is assembled with the main shaft body 311. The dustproof member 32 and the main shaft body 311 are assembled more conveniently.

[0163] For example, the wall of the seventh positioning groove 3267a of the main body 321 can be in contact with the surface of the second positioning protrusion 318 of the main shaft body 311. Figure 8B ) can fit with the surface of the third positioning protrusion 319 of the main shaft body 311.

[0164] In some embodiments, the first extension portion 322 can be located on one side of the peripheral side surface 3115 of the main shaft body 311. At least a portion of the surface of the first extension portion 322 facing the main shaft body 311 can be aligned with at least a portion of the peripheral side surface 3115 of the shaft portion 3111 of the main shaft body 311. It is understood that the first extension portion 322 can be aligned with the main shaft body 311 to eliminate a gap between the first extension portion 322 and the main shaft body 311, thereby preventing dust, sand, etc. from entering the interior of the main shaft 30A through the gap between the first extension portion 322 and the main shaft body 311 and affecting the reliability of the main shaft 30A and the folding mechanism 30.

[0165] In some embodiments, the second extension portion 323 may be located on the other side of the peripheral side surface 3115 of the main shaft body 311. At least a portion of the surface of the second extension portion 323 facing the main shaft body 311 may be in contact with at least a portion of the peripheral side surface 3115 of the shaft portion 3111 of the main shaft body 311. It will be appreciated that the second extension portion 323 may be in contact with the main shaft body 311 to eliminate a gap between the second extension portion 323 and the main shaft body 311, thereby preventing dust, sand, etc. from entering the interior of the main shaft 30A through the gap between the second extension portion 323 and the main shaft body 311 and affecting the reliability of the main shaft 30A and the folding mechanism 30.

[0166] Please refer to Figure 10 、 Figure 11A as well as Figure 12 , Figure 12 yes Figure 3The main shaft 30A shown is a schematic diagram of a portion of the structure in some embodiments. Figure 12 It mainly shows a schematic diagram of the assembly structure of the back cover 312 of the main shaft body 31 and the dustproof part 32.

[0167] In some embodiments, the main body 321 of the dustproof member 32 can be located in the mounting space 3120 of the back cover 312. The outer surface of the main body 321 can face the second inner surface of the back cover 312. It is understood that the back cover 312 can surround at least a portion of the dustproof member 32, which helps to improve the connection stability between the dustproof member 32 and the back cover 312 and prevent the dustproof member 32 from falling off.

[0168] In some embodiments, at least a portion of the outer surface of the main body 321 has the same shape as at least a portion of the second inner surface of the back cover 312. Exemplarily, the second surface 3215 of the main body 321 may face the third surface 3121a of the back cover 312. At least a portion of the second surface 3215 has the same shape as at least a portion of the third surface 3121a of the back cover 312. It is understood that the main body 321 of the dustproof member 32 may conform to the second inner surface of the back cover 312 to facilitate positioning and assembly of the dustproof member 32 with the back cover 312. It is understood that the shape of the entire second surface 3215 of the main body 321 may be the same as the shape of the third surface 3121a of the back cover 312. Alternatively, the shape of a portion of the second surface 3215 of the main body 321 may be the same as the shape of a portion of the third surface 3121a of the back cover 312.

[0169] For example, the shape of the sixth positioning protrusion 3265 of the main body 321 can be the same as the shape of the fourth positioning groove 3123 of the back cover 312. At least a portion of the sixth positioning protrusion 3265 can be located within the fourth positioning groove 3123. This improves the positioning effect when the dustproof member 32 is assembled with the back cover 312, making assembly between the dustproof member 32 and the back cover 312 more convenient.

[0170] In some embodiments, the second surface 3215 of the main body 321 can be aligned with the third surface 3121a of the back cover 312. This can, on the one hand, eliminate the gap between the main body 321 and the back cover 312, preventing dust, sand, etc. from entering the interior of the main shaft 30A through the gap between the main body 321 and the back cover 312, thereby affecting the reliability of the main shaft 30A and the folding mechanism 30. On the other hand, the main body 321 and the back cover 312 can be tightly aligned, thereby improving the connection stability between the main body 321 and the back cover 312. It is understood that the entire second surface 3215 of the main body 321 can be aligned with the third surface 3121a of the back cover 312. Alternatively, the second surface 3215 of the main body 321 can be aligned with the third surface 3121a of the back cover 312.

[0171] For example, the shape of the sixth positioning protrusion 3265 of the main body 321 can be the same as the shape of a portion of the fourth positioning groove 3123 of the back cover 312. A portion of the sixth positioning protrusion 3265 can be located within the fourth positioning groove 3123. This improves the positioning effect when the dust guard 32 is assembled with the main shaft body 311, making assembly between the dust guard 32 and the main shaft body 311 more convenient.

[0172] In some embodiments, the shape of the seventh positioning protrusion 3267b of the main body 321 can be the same as the shape of the first avoidance groove 3124 of the back cover 312. At least a portion of the seventh positioning protrusion 3267b can be located in the first avoidance groove 3124 (see Figure 7 ). In this way, the dustproof member 32 and the back cover 312 are better positioned when assembled. The dustproof member 32 and the back cover 312 are assembled more conveniently. For example, the surface of the seventh positioning protrusion 3267b of the main body 321 can be aligned with the surface of the first avoidance groove 3124 of the back cover 312.

[0173] In some embodiments, the shape of the eighth positioning protrusion 3268b of the main body 321 can be the same as the shape of the second avoidance groove 3125 of the back cover 312. At least a portion of the eighth positioning protrusion 3268b can be located within the second avoidance groove 3125. This improves the positioning effect when the dustproof member 32 is assembled with the back cover 312. The dustproof member 32 and the back cover 312 are assembled more conveniently. For example, the surface of the eighth positioning protrusion 3268b of the main body 321 can be aligned with the surface of the second avoidance groove 3125 of the back cover 312.

[0174] See also Figure 13 , Figure 13 yes Figure 3 The main shaft 30A shown is a schematic structural diagram in some embodiments.

[0175] In some embodiments, the first extension portion 322 can extend relative to one side of the spindle shaft body 31. It is understandable that the first extension portion 322 can extend relative to the spindle shaft body 31 in a direction away from the spindle shaft body 31 to one side of the spindle shaft body 31. Exemplarily, the first section 3221 of the first extension portion 322 can extend to one side of the spindle shaft body 31 along the X-axis direction (i.e., the direction perpendicular to the length extension direction of the spindle shaft body 31). The second section 3222 of the first extension portion 322 can extend to one side of the spindle shaft body 31 along the Y-axis direction (i.e., the direction of the length extension direction of the spindle shaft body 31). In this way, the first extension portion 322 of the dustproof member 32 can cover the gap between the spindle shaft body 31 and the first shell 10 in at least two directions, thereby achieving a better dustproof effect.

[0176] For example, the first extension portion 322 may be located on a side of the back cover 312 facing the main shaft body 311 and on a side of the first outer surface of the main shaft body 311. The first extension portion 322 may extend relative to the main shaft body 311 in a direction away from the main shaft body 311.

[0177] In some embodiments, the second extension portion 323 may extend from the other side of the spindle shaft 31. It is understood that the second extension portion 323 may extend from the spindle shaft 31 in a direction away from the spindle shaft 31 to one side of the spindle shaft 31. For example, the third section 3231 of the second extension portion 323 may extend along the X-axis direction (i.e., a direction perpendicular to the lengthwise extension direction of the spindle shaft 31) to one side of the spindle shaft 31. The fourth section 3232 of the first extension portion 322 may extend along the Y-axis direction (i.e., a direction perpendicular to the lengthwise extension direction of the spindle shaft 31) to one side of the spindle shaft 31.

[0178] For example, the second extension portion 323 may be located on a side of the back cover 312 facing the main shaft body 311 and on a side of the first outer surface of the main shaft body 311. The second extension portion 323 may extend relative to the main shaft body 311 in a direction away from the main shaft body 311.

Figure 15 The first extension portion 322 and the second extension portion 323 are schematically divided by dotted lines.

[0180] In some embodiments, when the electronic device 100 is in a closed state, at least a portion of the main shaft body 31 can be exposed relative to the first housing 10 and the second housing 20. It is understood that the main shaft body 31 can be completely exposed relative to the first housing 10 and the second housing 20. The main shaft body 31 can also be partially exposed relative to the first housing 10 and the second housing 20.

[0181] Exemplarily, the main shaft body 311 of the main shaft shaft 31 can be located inside the first shell 10 and the second shell 20, and the back cover 312 of the main shaft shaft 31 can be exposed relative to the first shell 10 and the second shell 20. The first extension portion 322 of the dustproof member 32 can extend relative to the main shaft shaft 31 toward the side closer to the first shell 10 and cover the gap between the main shaft shaft 31 and the first shell 10. In this case, at least a portion of the first extension portion 322 can be located between the main shaft shaft 31 and the first shell 10. In this way, dust, sand, etc. outside the electronic device 100 are not easily able to enter the interior of the electronic device 100 through the gap between the main shaft shaft 31 and the first shell 10, thereby affecting the reliability of the electronic device 100.

[0182] In some embodiments, when the electronic device 100 is in a closed state, at least a portion of the dustproof member 32 can cover the gap between the spindle shaft 31 and the first housing 10. It is understood that the dustproof member 32 can partially cover the gap between the spindle shaft 31 and the first housing 10. The dustproof member 32 can also completely cover the gap between the spindle shaft 31 and the first housing 10. For example, along the arrangement direction of the first housing 10 and the second housing 20, that is, along the Z-axis direction, at least a portion of the first segment 3221 of the first extension 322 can be located between the first housing 10 and the spindle shaft 31. Along the length extension direction of the spindle shaft 31, that is, along the Y-axis direction, at least a portion of the second segment 3222 of the first extension 322 can be located between the first housing 10 and the spindle shaft 31.

[0183] It is understood that, in a direction perpendicular to the longitudinal extension of the spindle shaft 31, the first section 3221 of the first extension portion 322 can cover the gap between the spindle shaft 31 and the first housing 10; and in a direction parallel to the longitudinal extension of the spindle shaft 31, the second section 3222 of the first extension portion 322 can cover the gap between the spindle shaft 31 and the first housing 10. This provides better dust protection for the spindle 30A and the folding mechanism 30.

[0184] For example, the first housing 10 may include a first inner surface 11 and a first outer surface 12 disposed in opposite directions. When the electronic device 100 is in a closed state, the first inner surface 11 of the first housing 10 may face the main shaft body 31. In this case, the first extension 322 may be located between the circumferential side surface 3115 of the main shaft body 311 and the first inner surface 11 of the first housing 10. The first extension 322 may cover the gap between the circumferential side surface 3115 of the main shaft body 311 and the first inner surface 11 of the first housing 10.

[0185] In some embodiments, the first extension portion 322 can contact the first inner surface 11 of the first shell 10. In this way, the first extension portion 322 can completely cover the gap between the main shaft body 31 and the first shell 10, thereby further improving the dustproof effect of the main shaft 30A and the folding mechanism 30. Figure 15 As shown, the first section 3221 of the first extension portion 322 may contact the first inner surface 11 of the first housing 10. Figure 16 As shown, the second section 3222 of the first extension portion 322 may contact the first inner surface 11 of the first housing 10 .

[0186] In some embodiments, the second extension portion 323 of the dustproof member 32 can extend relative to the main shaft body 31 toward the side closer to the second shell 20 and cover the gap between the main shaft body 31 and the second shell 20. In this case, part of the structure of the second extension portion 323 can be located between the main shaft body 31 and the second shell 20. In this way, when the electronic device 100 is in a closed state, the area of the gap of the electronic device 100 can be further reduced. Dust, sand, etc. outside the electronic device 100 are not likely to enter the interior of the electronic device 100 through the gap between the main shaft body 31 and the second shell 20, thereby affecting the reliability of the electronic device 100.

[0187] For example, along the arrangement direction of the first housing 10 and the second housing 20, that is, along the Z-axis direction, at least a portion of the third section 3231 of the second extension portion 323 may be located between the second housing 20 and the spindle shaft 31. Along the length extension direction of the spindle shaft 31, that is, along the Y-axis direction, at least a portion of the fourth section 3232 of the second extension portion 323 may be located between the second housing 20 and the spindle shaft 31.

[0188] It is understood that, in a direction perpendicular to the longitudinal extension of the spindle shaft 31, the third section 3231 of the second extension portion 323 can cover the gap between the spindle shaft 31 and the second housing 20; and in a direction parallel to the longitudinal extension of the spindle shaft 31, the fourth section 3232 of the second extension portion 323 can cover the gap between the spindle shaft 31 and the second housing 20. In this way, the second extension portion 323 of the dustproof member 32 can cover the gap between the spindle shaft 31 and the second housing 20 in at least two directions, providing a better dustproof effect.

[0189] For example, the second housing 20 may include a second inner surface 21 and a second outer surface 22 disposed in opposite directions. When the electronic device 100 is in a closed state, the second inner surface 21 of the second housing 20 may face the main shaft body 31. In this case, the second extension 323 may be located between the circumferential side surface 3115 of the main shaft body 311 and the second inner surface 21 of the second housing 20. The second extension 323 may cover the gap between the circumferential side surface 3115 of the main shaft body 311 and the second inner surface 21 of the second housing 20.

[0190] In some embodiments, the second extension portion 323 can contact the second inner surface 21 of the second shell 20. In this way, the second extension portion 323 can completely cover the gap between the main shaft body 31 and the second shell 20, thereby further improving the dustproof effect of the main shaft 30A and the folding mechanism 30. Figure 15 As shown, the third section 3231 of the second extension portion 323 can contact the second inner surface 21 of the second shell 20. The fourth section 3232 of the second extension portion 323 (see Figure 8A ) can be in contact with the second inner surface 21 of the second shell 20.

[0191] It is understood that in the longitudinal extension direction of the main shaft body 31 (ie, the Y-axis direction), the main shaft body 31 may include a first end portion 31a and a second end portion 31b disposed in opposite directions (see FIG. Figure 2 ). It can be understood that at the location of the first end 31a and the second end 31b, the gap between the main shaft body 31 and the first shell 10 and the second shell 20 is relatively large, and the intrusion of sand and dust is relatively serious, requiring special protection. To this end, in some embodiments, the dustproof member 32 of the main shaft 30A can be fixed to the first end 31a or the second end 31b of the main shaft body 31 to improve the dustproof effect of the first end 31a or the second end 31b. The above embodiment mainly describes the situation where the dustproof member 32 of the main shaft 30A is fixed to the first end 31a of the main shaft body 31.

[0192] In other embodiments, the number of dustproof members 32 can be at least two, with at least one dustproof member 32 fixed to the first end 31a of the main shaft body 31, and at least one dustproof member 32 fixed to the second end 31b of the main shaft body 31. In this way, the dustproof effect of the first end 31a and the second end 31b can be improved, thereby improving the dustproof effect of the electronic device 100. In other embodiments, the dustproof member 32 can also be fixed to the first end 31a, the second end 31b, or the structure between the first end 31a and the second end 31b of the main shaft body 31, and this application is not strictly limited to this.

[0193] See also Figure 17 , Figure 17 yes Figure 14The diagram shows a partial cross-sectional structure of the electronic device 100 when it is in an open state.

[0194] In some embodiments, when the electronic device 100 is in the unfolded state, the first housing 10 and the second housing 20 can cover the folding mechanism 30. The first inner surface 11 of the first housing 10 and the second inner surface 21 of the second housing 20 are oriented in the same direction, and can both face the flexible screen 40. In this case, the gap between the main shaft body 31 and the first housing 10 and the second housing 20 is small, making it difficult for dust, sand, etc. to enter the interior of the electronic device 100 through the gap between the main shaft body 31 and the first housing 10 and the second housing 20.

[0195] When the electronic device 100 is in the unfolded state, the dust guard 32 can be located inside the first and second housings 10, 20. For example, the main portion 321 of the dust guard 32 can be located between the first and second housings 10, 20, and the flexible screen 40. The first extension 322 of the dust guard 32 can be located between the first and second housings 10, 20, and the flexible screen 40. The second extension 323 can be located between the second and second housings 20 and the flexible screen 40. It is understood that in this embodiment of the present application, the dust guard 32 can be located inside the first and second housings 10, 20, and can be covered by the first and second housings 10, 20. The first and second housings 10, 20 can protect the dust guard 32, thereby extending the life of the dust guard 32. Furthermore, when the electronic device 100 transitions between the closed and unfolded states, the dust guard 32 does not move with the first and second housings 10, 20. This makes it less likely that the dust guard 32 will interfere with other components of the electronic device 100 and fall off. In addition, during the transition of the electronic device 100 between the closed state and the expanded state, the dustproof part 32 does not bend with the movement of the first shell 10 and the second shell 20. The dustproof part 32 is not easily damaged by fatigue due to bending and has a longer service life. The dustproof part 32 will not bend too many times, resulting in a decrease in its rebound ability, thereby affecting the shielding effect of the gap.

[0196] Please refer to Figure 18 and Figure 19 , Figure 18 yes Figure 5 The schematic diagram of the structure of the dustproof member 32 in other embodiments is shown. Figure 19 yes Figure 18 The structure diagram of the dustproof member 32 shown is shown at another angle. Figure 18 and Figure 19 The embodiment shown may include most of the technical contents of the above embodiment. The following mainly describes the differences between the two, and the majority of the same solutions are not repeated. It can be understood that the structure of the dustproof part 32 of this embodiment is the same as that of the above embodiment. Figure 8A The dust guard 32 shown is similarly constructed.

[0197] In this embodiment, the main body 321 of the dustproof member 32 may include a first portion 321a, a second portion 321b, and a third portion 321c. The third portion 321c is connected between the first portion 321a and the second portion 321b. The first portion 321a is connected to the first extension portion 322 of the dustproof member 32. The second portion 321b is connected to the second extension portion 323 of the dustproof member 32.

[0198] For example, a portion of the first portion 321a may constitute the first sub-body portion 3211 of the dustproof member 32 (see Figure 8A A portion of the second portion 321b may constitute the second sub-body portion 3212 of the dust member 32 (see Figure 8A ); another portion of the first portion 321a, another portion of the second portion 321b and the third portion 321c may together constitute the third sub-body portion 3213 of the dust member 32 (see Figure 8A In some other embodiments, the first portion 321a may also constitute the first sub-body portion 3211 of the dustproof member 32; the second portion 321b may also constitute the second sub-body portion 3212 of the dustproof member 32; and the third portion 321c may also constitute the third sub-body portion 3213 of the dustproof member 32.

[0199] For example, the main body 321 may be provided with a first groove 3211a and a second groove 3211b. The first groove 3211a and the second groove 3211b may be recessed from the second surface 3215 of the main body 321 toward the first surface 3214. The first groove 3211a may be located in the first portion 321a of the main body 321, and the second groove 3211b may be located in the second portion 321b of the main body 321.

[0200] For example, the main body 321 may further include a first protrusion 3212a and a second protrusion 3212b, wherein the first protrusion 3212a may be protruded from the bottom wall of the first groove 3211a, and the second protrusion 3212b may be protruded from the bottom wall of the second groove 3211b.

[0201] For example, the third portion 321c may include a fifth surface 3211c and a sixth surface 3212c disposed in opposite directions. The fifth surface 3211c may be a portion of the first surface 3214 of the main body 321. The sixth surface 3212c may be a portion of the second surface 3215 of the main body 321. The third portion 321c may be provided with a first through hole 3213c and a second through hole 3214c spaced apart from each other. The first through hole 3213c and the second through hole 3214c respectively extend through the fifth surface 3211c and the sixth surface 3212c of the third portion 321c.

[0202] In this embodiment, the third portion 321c of the main body 321 can be embedded in the first portion 321a and the second portion 321b. This can improve the connection stability between the third portion 321c and the first portion 321a and the second portion 321b, and can also help improve the integrity of the dustproof member 32 and facilitate subsequent assembly of the dustproof member 32.

[0203] For example, part of the third portion 321c may be located in the first groove 3211a and part of the third portion 321c may be located in the second groove 3211b. At least part of the first protrusion 3212a of the first portion 321a may be located in the first through hole 3213c, and at least part of the second protrusion 3212b of the second portion 321b may be located in the second through hole 3214c.

[0204] Exemplarily, the dustproof member 32 can be manufactured using an insert injection molding process. It is understood that insert injection molding refers to a molding process in which a pre-prepared insert of another material (such as metal) is placed in a mold and then injection molded. The plastic and the insert are then bonded and solidified in the mold to form an integrated product. For example, in this embodiment, the third portion 321c of the main body 321 can be pre-formed using a blanking process, and then the third portion 321c is fixed in an appropriate position in the mold. The first portion 321a of the main body 321, the second portion 321b of the main body 321, the first extension portion 322, and the second extension portion 323 are then manufactured using an injection molding process.

[0205] Illustratively, the main body 321 may further include a recessed area 327. The recessed area 327 may extend from the first surface 3214 of the main body 321 toward the second surface 3215. Illustratively, the recessed area 327 may be located in the third portion 321c. In this case, the recessed area 327 may extend from the fifth surface 3211c toward the sixth surface 3212c. Illustratively, the recessed area 327 may communicate with the fifth positioning groove 3262 and the sixth positioning groove 3264.

[0206] For example, the main body 321 may not include the fourth positioning protrusion 3261 (see Figure 8B ). It is understandable that the third sub-body portion 3213 of this embodiment may not include Figure 8B The fourth positioning protrusion 3261 of the embodiment shown. Therefore, the third sub-body portion 3213 of this embodiment may not include the portion of the structure where the fourth positioning protrusion 3261 is located, thereby reducing the size of the third sub-body portion 3213 of the main body portion 321. It will be understood that by reducing the size of the third sub-body portion 3213, the main body portion 321 can avoid some structural components of the spindle shaft 31.

[0207] In this embodiment, both the first portion 321a and the second portion 321b are flexible. The first portion 321a and the second portion 321b can deform when subjected to force. This prevents the first portion 321a and the second portion 321b from interfering with or abrading the main shaft 311 and back cover 312 of the main shaft 31, or the first and second housings 10 and 20 during the unfolding and folding process of the electronic device 100. Exemplary materials for the first portion 321a and the second portion 321b include silicone, soft rubber, and the like. It can be understood that materials such as soft glue and silicone can better imitate the shape of the main shaft shaft 31, the first shell 10 and the second shell 20, so that the shape of the dustproof part 32 can better match the shape of the gap between the main shaft shaft 31 and the first shell 10 and the second shell 20. For example, the width of the dustproof part 32 at different positions in the gap can match the width of the gap at the position, so that the dustproof part 32 can better block the gap between the main shaft shaft 31 and the first shell 10 and the second shell 20, and the dustproof effect is better.

[0208] Exemplarily, the material of the third portion 321c can be a metal material, such as carbon steel, stainless steel, iron, aluminum, copper, or other weldable metal materials. In this case, the third portion 321c can be welded to the back cover 312. It is understood that the third portion 321c can be pre-fixed to the back cover 312 to form a single unit, and then the back cover 312 and the dust guard 32 can be assembled together with the main shaft body 311. Compared to methods where the dust guard 32 is fixed to the back cover 312 or the main shaft body 311 by dispensing glue, the third portion 321c of this embodiment is fixed to the back cover 312 by welding, eliminating the need for a pressure-maintaining operation. This makes assembly between the dust guard 32 and the back cover 312 more convenient and faster, and improves production efficiency. Furthermore, the third portion 321c is fixed to the back cover 312 by welding, which ensures a more secure connection between the dust guard 32 and the back cover 312, making it less likely for the dust guard 32 to fall off. Furthermore, when the third portion 321c is made of materials such as steel or iron, it can have greater rigidity and be less susceptible to deformation. The dust guard 32 can be provided with positioning structures, such as positioning posts or positioning holes, on the third portion 321c to facilitate positioning of the dust guard 32 with the spindle body 311 and the back cover 312, thereby improving the positioning accuracy of the dust guard 32 during assembly and achieving better positioning of the dust guard 32.

[0209] See also Figures 18 to 20 , Figure 20 yes Figure 3 The main shaft 30A shown is a schematic diagram of a partial cross-sectional structure cut along DD in some other embodiments. Figure 20 The spindle 30A shown may include Figure 18 The dust guard 32 is shown.

[0210] In some embodiments, at least a portion of the third portion 321c of the main body 321 can be located between the main shaft body 311 and the back cover 312 and fixedly connected to the back cover 312. For example, the third portion 321c can be located between the first surface 3113 of the main shaft body 311 and the third surface 3121a of the back cover 312. The fifth surface 3211c of the third portion 321c can face the first surface 3113 of the main shaft body 311. In this case, the recessed area 327 of the main body 321 can face the first surface 3113 of the main shaft body 311, thereby avoiding a portion of the structure on the main shaft body 311.

[0211] For example, at least a portion of the fifth surface 3211c of the third portion 321c has the same shape as at least a portion of the first surface 3113 of the spindle body 311. For example, at least a portion of at least one of the fifth positioning groove 3262, the sixth positioning groove 3264, and the fifth positioning protrusion 3263 may be located in the third portion 321c. This improves the positioning of the dust guard 32 during assembly with the spindle body 311, making assembly between the dust guard 32 and the spindle body 311 more convenient.

[0212] For example, the sixth surface 3212c of the third portion 321c can face the third surface 3121a of the back cover 312. At least a portion of the sixth surface 3212c of the third portion 321c has the same shape as at least a portion of the third surface 3121a of the back cover 312. This improves the positioning of the dustproof member 32 during assembly with the back cover 312, making assembly between the dustproof member 32 and the back cover 312 more convenient.

[0213] See also Figure 21 , Figure 21 yes Figure 5 The dustproof member 32 shown is a schematic structural diagram in other embodiments. Figure 20 The embodiment shown may include most of the technical contents of the above embodiment. The following mainly describes the differences between the two, and the majority of the same solutions are not repeated. It can be understood that the structure of the dustproof part 32 of this embodiment is the same as that of the above embodiment. Figure 8A The dust guard 32 shown is similarly constructed.

[0214] In this embodiment, the main body 321 of the dustproof member 32 may include a fourth portion 321d and a fifth portion 321e. The fifth portion 321e is fixed to the fourth portion 321d. The fourth portion 321d connects the first extension portion 322 and the second extension portion 323 of the dustproof member 32. For example, a portion of the fourth portion 321d may constitute the first sub-main body 3211 of the dustproof member 32 (see Figure 8A A portion of the fourth portion 321d may constitute the second sub-body portion 3212 of the dust member 32 (see Figure 8A); a portion of the fourth portion 321d and the fifth portion 321e may together constitute the third sub-body portion 3213 of the dust member 32 (see Figure 8A ).

[0215] In other embodiments, a portion of the fourth portion 321d may constitute the first sub-body portion 3211 of the dustproof member 32, and another portion may constitute the second sub-body portion 3212 of the dustproof member 32; the fifth portion 321e may constitute the third sub-body portion 3213 of the dustproof member 32.

[0216] In this embodiment, the fifth portion 321e can be embedded in the fourth portion 321d. This can improve the connection stability between the fifth portion 321e and the fourth portion 321d, and can also improve the integrity of the dustproof member 32 and facilitate subsequent assembly of the dustproof member 32.

[0217] For example, the main body 321 may be provided with a third groove 3211d. The third groove 3211d may be recessed from a portion of the second surface 3215 of the main body 321 toward the first surface 3214. The third groove 3211d may be located in the fourth portion 321d of the main body 321. At least a portion of the fifth portion 321e may be located within the third groove 3211d.

[0218] In this embodiment, the fourth portion 321d is a flexible portion. This prevents interference or wear between the fourth portion 321d and the main shaft body 311, back cover 312, first housing 10, and second housing 20 during the unfolding and folding process of the electronic device 100. The fourth portion 321d can deform when subjected to force. The material of the fourth portion 321d may include silicone, soft rubber, or the like. It is understood that materials such as soft rubber and silicone can effectively conform to the shape of the main shaft body 31, first housing 10, and second housing 20, allowing the shape of the dust guard 32 to effectively match the shape of the gap between the main shaft body 31 and the first housing 10 and second housing 20. For example, the width of the dust guard 32 at different locations within the gap can match the width of the gap at that location. This allows the dust guard 32 to effectively block the gap between the main shaft body 31 and the first housing 10 and second housing 20, achieving a better dustproof effect.

[0219] Exemplarily, the material of the fifth portion 321e can be a metal material, such as carbon steel, stainless steel, iron, aluminum, copper, or other weldable metal materials. In this case, the fifth portion 321e can be welded to the back cover. It is understood that the fifth portion 321e can be pre-fixed to the back cover 312 to form a single unit, and then the back cover 312 and the dust guard 32 can be assembled together with the main shaft body 311. Compared to methods where the dust guard 32 is fixed to the back cover 312 or the main shaft body 311 by dispensing glue, the fifth portion 321e of this embodiment is fixed to the back cover 312 by welding, eliminating the need for a pressure-maintaining operation. This makes assembly between the dust guard 32 and the back cover 312 more convenient and quick, and improves production efficiency. Furthermore, the connection between the dust guard 32 and the back cover 312 is more secure, making it less likely for the dust guard 32 to fall off. Furthermore, when the fifth portion 321e is made of materials such as steel and iron, it can have greater rigidity and be less prone to deformation. The dustproof part 32 can be provided with some positioning structures on the third part 321c, such as positioning columns or positioning holes, to facilitate the positioning between the dustproof part 32 and the main shaft body 311 and the back cover 312, thereby improving the positioning accuracy of the dustproof part 32 during assembly and making the positioning effect of the dustproof part 32 better.

[0220] Please refer to Figures 22 to 24 , Figure 22 yes Figure 2 The schematic diagram of a partial cross-section structure of the electronic device 100 in some other embodiments is shown. Figure 23 yes Figure 22 The schematic diagram of a portion of the structure of the electronic device 100 in some embodiments is shown. Figure 24 yes Figure 22 The schematic diagram of the partial cross-section structure of the electronic device 100 is shown along EE. Figure 22 Mainly shows Figure 2 FIG. 1 is a schematic cross-sectional view of a portion of the structure of the electronic device 100 within the dotted box at another angle. Figure 23 The first housing 10 , the second housing 20 and the dustproof member 32 are mainly shown. Figures 22 to 24 The illustrated embodiment may include most of the technical contents of the previous embodiment. The following mainly describes the differences between the two, and most of the same solution contents between the two will not be repeated.

[0221] In this embodiment, the electronic device 100 may include a first housing 10, a second housing 20, a folding mechanism 30, and a dustproof member 32. The structures and arrangements of the first housing 10 and the second housing 20 in this embodiment are the same as or similar to those of the first housing 10 and the second housing 20 in any of the above embodiments. For the structure of the main shaft 30A in this embodiment, reference may be made to the description of the structure of the main shaft body 31 in any of the above embodiments.

[0222] The folding mechanism 30 may include a main shaft 30A and a connecting assembly (not shown). The structure and configuration of the folding mechanism 30 in this embodiment are substantially the same as those of the folding mechanism 30 in any of the above embodiments, except that, in this embodiment, the main shaft 30A of the folding mechanism 30 may not include a dust guard 32. It is understood that the structure and configuration of the main shaft 30A in this embodiment are the same or similar to the structure of the main shaft body 31 in any of the above embodiments. For the structure of the main shaft 30A in this embodiment, reference may be made to the relevant description of the structure of the main shaft body 31 in any of the above embodiments. In this embodiment, the dust guard 32 may be fixed to the first housing 10. When the electronic device 100 is in the closed state, at least a portion of the dust guard 32 may cover the gap between the main shaft 30A and the first housing 10. It is understood that the dust guard 32 may partially cover the gap between the main shaft 30A and the first housing 10. Alternatively, the dust guard 32 may completely cover the gap between the main shaft 30A and the first housing 10.

[0223] It's understandable that in conventional electronic devices, a gap is typically left between the first and second housings and the folding mechanism to facilitate relative expansion and closure of the first and second housings. When the first and second housings are closed, a significant gap exists between the folding mechanism and the first and second housings. Dust, sand, and other particles from the outside of the electronic device can easily enter through this gap, affecting its reliability.

[0224] To this end, in the embodiment of the present application, a dustproof member 32 is provided and fixed to the first housing 10, so that when the electronic device 100 is in the closed state, at least a portion of the dustproof member 32 can cover the gap between the main shaft 30A and the first housing 10. In this way, dust, sand, etc. outside the electronic device 100 are not easily able to enter the interior of the electronic device 100 through the gap between the main shaft 30A and the first housing 10, thereby affecting the reliability of the electronic device 100.

[0225] For example, a portion of the dust guard 32 may be fixed to the first inner surface 11 of the first housing 10, and another portion may be fixed to the second inner surface 21 of the second housing 20. When the electronic device 100 transitions between the closed and expanded states, the dust guard 32 may follow the movement of the first and second housings 10, 20, and move relative to the main shaft 30A. When the electronic device 100 is in the closed state, the dust guard 32 may fill the gap between the first and second housings 10, 20, and the main shaft 30A, thereby further preventing dust, sand, and the like from entering the interior of the electronic device 100 through the gap between the first or second housing 10, 20, and the main shaft 31. For example, when the electronic device 100 is in the closed state, a portion of the dust guard 32 may abut between the back cover 312 and the first housing 10 to fill the gap therebetween; another portion of the dust guard 32 may abut between the back cover 312 and the second housing 20 to fill the gap therebetween. For example, when the electronic device 100 is in a closed state, a portion of the dustproof member 32 can be abutted between the main shaft body 311 and the first shell 10 to fill the gap between the main shaft body 311 and the first shell 10; a portion of the dustproof member 32 can be abutted between the main shaft body 311 and the second shell 20 to fill the gap between the main shaft body 311 and the second shell 20.

[0226] For example, the dustproof member 32 can be a flexible member. This prevents the dustproof member 32 from interfering with or abrading the main shaft 30A or other components of the electronic device 100 during unfolding and folding. For example, the dustproof member 32 can be made of foam, a soft rubber with a low modulus, or the like. It is understood that when the dustproof member 32 is made of a soft rubber with a low modulus, the surface of the dustproof member 32 can be coated with grease to reduce friction, thereby facilitating the unfolding and folding of the first housing 10 and the second housing 20.

[0227] In this embodiment, the dustproof member 32 can be made of foam. The manufacturing process for foam is mature, and the semi-finished foam can be directly cut and shaped. Therefore, the foam can be cut to match the shape of the gap to be blocked. This simplifies the processing of the dustproof member 32 and shortens the cutting time, which helps shorten the production time of the dustproof member 32 and improve production efficiency.

[0228] It will be understood that in some examples, the dustproof member 32 may include at least two foams, at least one of which may be fixed to the first inner surface 11 of the first shell 10 to fill the gap between the first shell 10 and the main shaft 30A; and at least one foam may be fixed to the second inner surface 21 of the second shell 20 to fill the gap between the second shell 20 and the main shaft 30A.

[0229] It should be understood that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0230] The above are only some of the embodiments of this application, and the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
