Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to an electronic device. Background Art

[0002] The emergence of foldable screens has solved the contradiction between large screens and portability, and the market demand for electronic devices with foldable screens is gradually increasing. Among them, the hinge mechanism and the flexible screen are the key components to achieve screen folding. The flexible screen can be folded and unfolded within a certain angle range under the rotation of the hinge mechanism. The bendable area of ​​the flexible screen is called the axis zone screen. In order to facilitate the switching of the flexible screen between the folded state and the unfolded state, the end of the body frame of the electronic device along the axial direction is provided with an avoidance space, which is used to avoid the edge of the axis zone screen along the axial direction. Therefore, when the electronic device is in the unfolded state, the end face of the axis zone screen along the axial direction is exposed, which not only affects the aesthetics, but also the edge of the axis zone screen is easily damaged when impacted by external force.

[0003] In the prior art, in order to shield the end faces of the axis area screen along the axial direction, T-shaped shielding members are usually provided at both ends of the axis direction of the rotating shaft mechanism. However, along the axial direction, the gap between the T-shaped shielding member and the end faces of the axis area screen is still large, which increases the risk of dust or liquid entering the interior of the electronic device; in addition, when the electronic device falls, the probability of damage to the axis area screen is still relatively high. Utility Model Content

[0004] An embodiment of the present invention provides an electronic device, which further shields the axial assembly gap between the shielding member and the axial area screen on the basis of the shielding member shielding the end face of the axial area screen along the axial direction, thereby improving the appearance refinement and screen reliability.

[0005] In a first aspect, the present invention provides an electronic device comprising a first housing, a second housing, a hinge mechanism, and a display screen, wherein the first housing and the second housing are respectively disposed on opposite sides of the hinge mechanism and are rotatably connected via the hinge mechanism. The display screen continuously covers the first housing, the hinge mechanism, and the second housing. The display screen includes a bendable region, which covers the hinge mechanism and can be bent or unfolded about the axis of the hinge mechanism. Along the axial direction of the hinge mechanism, the end of the first housing includes a first avoidance opening, and the end of the second housing includes a second avoidance opening. When the electronic device is in a flattened state, the first avoidance opening and the second avoidance opening, located at the same axial end of the electronic device, form a storage space. The hinge mechanism includes a first shielding member, which is accommodated in the storage space and, along the axial direction, covers at least a portion of the end surface of the bendable region. The display screen includes a stacked protective film layer and a display screen body, wherein the protective film layer is located on the display surface side of the display screen body. The protective film layer includes a first extending portion, and an axial distance X1 between the first extending portion and the first shielding member is smaller than an axial distance X2 between the display screen body and the first shielding member.

[0006] In the above-mentioned electronic device, the first avoidance opening and the second avoidance opening are used to avoid the axial end of the bendable area so that the bendable area can be bent smoothly, thereby enabling the electronic device to be folded. When the electronic device is in a flattened state, the end surface of the bendable area is in an exposed state along the axial direction of the hinge mechanism, and the first shielding member can cover at least part of the above-mentioned exposed end surface of the bendable area to prevent it from being damaged, thereby improving the reliability of the bendable area of ​​the display screen. Wherein, the protective film layer includes a first extension portion, and the axial spacing X1 between the first extension portion and the first shielding member is smaller than the axial spacing X2 between the display screen body and the first shielding member, so that the first extension portion can shield the axial spacing between the display screen body and the first shielding member, which not only improves the appearance of the electronic device, but also prevents dust or liquid from entering the interior of the electronic device through the above-mentioned gap. In addition, since the first extension portion extends beyond the edge of the display screen body in the axial direction, the first extension portion can also play a role in protecting the display screen body.

[0007] Among them, the electronic devices in the present invention include mobile phones, tablet computers, laptops, wearable devices or smart TVs, etc.

[0008] In one possible implementation, along the axial direction of the hinge mechanism, an axial spacing X1 between the first shielding member and an edge of the first extension portion proximate to the first shielding member is greater than zero to prevent interference between the first shielding member and the first extension portion. Alternatively, along the axial direction, an axial spacing X1 between the first shielding member and an edge of the first extension portion proximate to the first shielding member is 0.15 mm ≤ X1 ≤ 0.35 mm. The value of X1 is set based on practical circumstances to ensure that the first extension portion can cover the axial spacing between the first shielding member and the display screen while also preventing interference between the first extension portion and the first shielding member.

[0009] Possibly, an axial distance X3 between an edge of the first extension portion and an edge of the display screen body at the same end is 0.1 mm≤X3≤0.25 mm, so that the first extension portion can protect the edge of the display screen body.

[0010] In one possible implementation, the first extension is provided with a first chamfer and a second chamfer. The first chamfer faces the inner wall of the first escape opening of the first shell to prevent interference between the first extension and the first shell; the second chamfer faces the inner wall of the second escape opening of the second shell to prevent interference between the second extension and the second shell. Both the first and second chamfers can be curved to reduce edge sharpness and reduce stress concentration.

[0011] Wherein, when the electronic device is in a flattened state, the first extension portion is spaced apart from the inner wall of the first avoidance opening so as to avoid interference between the first extension portion and the first shell. The first extension portion is spaced apart from the inner wall of the second avoidance opening so as to avoid interference between the first extension portion and the second shell. Exemplarily, when the electronic device is in a flattened state, the minimum distance x4 between the first extension portion and the inner wall of the first avoidance opening is 0.15mm≤x4≤0.30mm, and the minimum distance y4 between the first extension portion and the inner wall of the second avoidance opening is 0.15mm≤y4≤0.30mm. Wherein, the values ​​of x4 and y4 are set according to actual conditions to take into account the effect of the first extension portion shielding the axial distance between the first shielding member and the display screen and avoiding interference between the first extension portion and the first shell or the second shell.

[0012] In one possible implementation, the display screen body includes a stacked cover layer and a functional stack, with the cover layer interposed between the functional stack and the protective film layer. To protect the functional stack, the cover layer includes a second extension at the end along the axial direction of the hinge mechanism. The axial spacing between the second extension and the first shielding member is smaller than the axial spacing between the functional stack and the first shielding member, and the second extension extends into the accommodation space.

[0013] The present invention does not specifically limit the axial spacing between the second extension portion and the first shielding member, and the axial spacing between the functional stack and the first shielding member. For example, along the axial direction of the rotating shaft mechanism, the axial spacing X5 between the edge of the second extension portion and the edge of the functional stack located at the same end is 0.2mm≤X5≤0.4mm.

[0014] It is understood that the simultaneous expansion of the cover layer and the protective film layer can improve the rigidity of the display screen and strengthen the shielding and protection of the edges of the functional stack, thereby reducing or preventing bumps or damage to the functional stack. Specifically, when the cover layer and the protective film layer are simultaneously expanded, the axial spacing X6 between the edge of the first extension portion and the edge of the second extension portion located at the same end is 0 ≤ X6 ≤ 0.1 mm, so that the protective film layer can protect the cover layer and prevent the edge of the cover layer from being exposed.

[0015] To further enhance the structural reliability of the display screen, a protective structural layer is provided along the axial direction on the end face of the functional stack facing the accommodation space and on the surface of the second extension facing away from the protective film layer to enhance the strength and rigidity of the edge of the display screen body. Furthermore, the protective structural layer ensures good sealing between the cover layer and the functional stack, as well as between the functional stack itself, thereby effectively preventing and reducing the ingress of dust or liquids into the interior of the display screen. Optionally, the protective structural layer can be produced by dispensing glue. For example, adhesive is applied to the end faces of the functional stack facing the first and second avoidance openings, as well as on the surface of the second extension facing away from the protective film layer, to form a continuous protective layer. This not only ensures a firm bond between the second extension and the functional stack, but also enables the protective structural layer to act as a buffer, thereby protecting the functional stack from direct impact from external forces.

[0016] It is understood that when the adhesive is applied to the end surface of the functional stack facing the accommodation space, to ensure that the protective structural layer completely covers this surface, the amount of adhesive overflow on the end of this surface facing away from the cover layer is less than or equal to 2 mm. The display screen body also includes a support layer disposed on the side of the functional stack facing away from the cover layer. The support layer supports the functional stack and the cover layer. Therefore, the adhesive applied to this surface diffuses from the functional stack to the support layer, fully protecting the edges of the functional stack.

[0017] In order to ensure that the adhesive completely covers the surface of the second extension part facing away from the protective film layer, the amount of adhesive overflow on the edge of the first avoidance opening and the second avoidance opening of the surface of the second extension part facing away from the protective film layer is less than or equal to 0.1 mm, so as to avoid excessive adhesive overflow affecting the appearance of the display screen.

[0018] In one possible implementation, the display screen body further includes a flexible protective layer positioned between the cover layer and the functional stack. Exemplarily, the flexible protective layer may be a transparent film such as an ultra-thin flexible glass (UTG) layer, a polyimide layer, a polyethylene terephthalate layer, or aramid. Axially, the second extension of the cover layer is positioned outside the edge of the flexible protective layer. In other words, the axial spacing between the second extension and the first shielding member is smaller than the axial spacing between the flexible protective layer and the first shielding member. The second extension protects the edge of the flexible protective layer.

[0019] Exemplarily, an axial distance X7 between an edge of the second extension portion and an edge of the flexible protective layer located at the same end is 0.2 mm≤X7≤0.4 mm.

[0020] In addition, along the axial direction, the size of the flexible protective layer can be smaller than the cover layer and the functional stack, that is, a groove is formed between the cover layer, the flexible protective layer and the functional stack, and the groove is filled with adhesive to further protect the flexible protective layer.

[0021] In one implementation, the electronic device further includes a second shielding member connected to the first shielding member. The second shielding member includes a shielding unit that extends from the shielding portion toward the display screen. The shielding unit's projection, along the stacking direction of the display screens, covers at least a portion of the projection of the gap between the first extension portion and the first shielding member. The second shielding member can shield the axial distance between the display screen and the first shielding member, preventing dust, liquid, etc. from entering the electronic device through the gap and preventing the risk of being snagged or damaged.

[0022] In the present invention, the first shielding member and the second shielding member are not an integrally formed structure, so the second shielding member can be installed after the display screen, the first shielding member and the hinge mechanism are assembled, thereby ensuring that the gap between the display screen and the first shielding member remains unchanged, which helps to achieve a narrow-frame design for the electronic device.

[0023] The present invention does not specify the specific shape and structure of the second shielding member, as long as it can function to shield the axial gap between the display screen and the first shielding member. Optionally, the second shielding member further includes a connecting member, and the shielding unit is connected to the first shielding member via the connecting member, and the connecting member extends along the stacking direction of the display screen.

[0024] In a possible implementation, along the stacking direction, a minimum distance X8 between the shielding unit and the display screen is greater than or equal to 0.25 mm to avoid interference between the shielding unit and the display screen.

[0025] In one possible implementation, the shielding unit is a plate-like structure parallel to the display screen, and the connector is connected to the surface of the shielding unit facing the display screen. To ensure a secure connection between the connector and the first shielding member, the connector and the first shielding member are riveted together, and the joint between the connector and the first shielding member is filled with adhesive to bond the connector and the first shielding member, thereby enhancing the connection strength between the second shielding member and the first shielding member and preventing the second shielding member from shaking or falling off.

[0026] In one possible implementation, the second shielding member has a strength greater than or equal to 1800 MPa and can be made of spring steel, etc. Spring steel typically has a high elastic limit and good toughness, which can resist impact and vibration, thereby protecting the display and extending its service life.

[0027] In one possible implementation, the hinge mechanism includes a hinge, which is integrally formed with the first shielding member and secured to the first shielding member by means of snap-fitting, gluing, or other methods. This integral hinge mechanism not only simplifies the structure and requires no assembly, but also helps improve the drop resistance of the entire device, ensuring the reliability of the overall structure.

[0028] In a second aspect, the utility model also provides another electronic device, which includes a first shell, a second shell, a hinge mechanism and a display screen. The first shell and the second shell are respectively arranged on opposite sides of the hinge mechanism. The first shell and the second shell are rotatably connected by the hinge mechanism so that the electronic device can be folded or unfolded. The display screen continuously covers the first shell, the hinge mechanism and the second shell. The display screen includes a bendable area, and the bendable area covers the hinge mechanism. Along the axial direction of the hinge mechanism, the end of the first shell includes a first avoidance opening, and the end of the second shell includes a second avoidance opening. When the electronic device is in a flattened state, the first avoidance opening and the second avoidance opening located at the same end of the electronic device along the axial direction form a accommodating space. The hinge mechanism includes a first shielding member, which is accommodated in the accommodating space, and along the axial direction, the first shielding member covers at least a portion of the end surface of the bendable area to protect it from impact by external forces and improve its service life.

[0029] In addition, the electronic device also includes a third shielding member, which is accommodated in the accommodating space. One end of the third shielding member is connected to the first shell, and the other end of the third shielding member is slidably connected to the second shell. Along the stacking direction of the display screen, the projection of the third shielding member covers at least part of the projection of the gap between the first shielding member and the display screen. The third shielding member can play a role in shielding the axial gap between the first shielding member and the display screen, preventing foreign matter from entering the interior of the electronic device through the above-mentioned gap, and can protect the edge of the display screen.

[0030] It is understood that one end of the third shielding member is connected to the first housing, and the other end of the third shielding member is slidably connected to the second housing, so that the third shielding member can bend and deform when the electronic device is folded. Optionally, the third shielding member has a folding area that can bend or unfold around the axis of the hinge mechanism. The folding area is provided with an opening. When the third shielding member is bent, the opening can disperse stress, preventing stress concentration in the folding area, thereby reducing or preventing cracks or breakage in the folding area during the bending process.

[0031] In addition, along the stacking direction of the display screen, the opening passes through the third shielding member to improve its fatigue resistance. The number of the openings can be one, two, or more, depending on actual needs.

[0032] In one possible implementation, the third shielding member is provided with a covering layer on both its surface facing the display screen and its surface facing away from the display screen. The covering layer covers at least the opening to conceal the opening, enhancing the aesthetics and preventing the opening from scratching the display screen. The covering layer is made of at least one of polyester film and thermoplastic urethane (TPU). Both polyester film and TPU have excellent elasticity, toughness, and wear resistance, and can maintain good mechanical properties even after repeated bending.

[0033] Optionally, the thickness of the third shielding member along the display screen stacking direction is 0.02-0.03 mm to minimize the overall thickness of the electronic device. The third shielding member has a strength of 1500 MPa or greater. To meet this strength requirement, the third shielding member can be a stainless steel sheet. Optionally, the third shielding member can be integrally formed, for example, as a continuous steel sheet, to facilitate smoother bending and deformation.

[0034] In one possible implementation, the axial spacing X9 between the edge of the third shielding member close to the first shielding member and the edge of the display screen close to the first shielding member is 0.10mm≤X9≤0.40mm. The specific size of X9 can be designed according to actual conditions to ensure that the third shielding member can shield the edge of the bendable area and the axial spacing between the first shielding member and the display screen, to prevent the edge of the bendable area from being damaged by external force, or foreign matter from entering the interior of the display screen through the gap, so as to improve the service life of the display screen.

[0074] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0075] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, the singular expressions "a", "an", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0076] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present invention. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet 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," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0077] The electronic device provided by the present invention may be, but is not limited to, a user device or terminal device. For example, the electronic device may be a tablet computer, a personal digital assistant, a handheld device with wireless communication capabilities, a computing device, an in-vehicle device, a wireless terminal in a wearable device, a wireless terminal in an unmanned vehicle, a wireless terminal in a telemedicine device, or other mobile or fixed terminal. The electronic device provided by the present invention will be specifically described below using a mobile phone as an example.

[0078] Figure 1 is a schematic diagram of the structure of an electronic device in a flattened state. Figure 2 is a schematic diagram of the structure of an electronic device in a folded state, referring to Figure 1 and Figure 2 The electronic device includes a first housing 100, a second housing 200, a hinge mechanism 300, and a display screen 400. The first housing 100 and the second housing 200 are respectively disposed on opposite sides of the hinge mechanism 300, and the first housing 100 and the second housing 200 are rotatably connected by the hinge mechanism 300, so that the electronic device can be folded and unfolded within a certain angle range under the rotation of the hinge mechanism 300. The display screen 400 continuously covers the first housing 100, the hinge mechanism 300, and the second housing 200. The display screen 400 includes a bendable region 01, which covers the hinge mechanism 300 and can bend or unfold around the axis of the hinge mechanism 300.

[0079] In the present invention, the electronic device can be an inward folding electronic device or an outward folding electronic device. In some embodiments, Figure 2 As shown, when the electronic device is an inward-folding electronic device, the bendable region 01 is in a bent state, and the display screen 400 is invisible to the user, thereby preventing the display screen 400 from being damaged by hard objects. In other embodiments, when the electronic device is an outward-folding electronic device, the bendable region 01 is in a bent state, and the display screen 400 is visible to the user, facilitating small-screen operation or single-handed operation.

[0080] It is understandable that the first shell, the second shell and the hinge mechanism form a set of folding components. The electronic device may include one, two or more sets of the above folding components. When the electronic device includes only one set of folding components, the electronic device can only be folded once. When the electronic device includes at least two sets of folding components, the shells of any two adjacent folding components can be fixedly connected or rotatably connected so that the electronic device can be folded twice or more. In order to facilitate the switching of the flexible screen between the folded state and the unfolded state, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of an existing T-shaped shielding member shielding the end surface of the bendable area. Along the axial direction D1 of the rotating shaft mechanism 300, the end of the first shell 100 includes a first avoidance opening 02, and the end of the second shell 200 includes a second avoidance opening 03. The first avoidance opening 02 and the second avoidance opening 03 form a avoidance space. When the bendable area 01 is in the bent state, the avoidance space is used to avoid the axial end of the bendable area 01. However, if Figure 3 As shown, when the device is flattened, the first and second relief openings 02 and 03, located at the same axial end of the electronic device, form a receiving space 04, leaving the axial end surface of the bendable region 01 exposed and susceptible to damage from external forces. Therefore, the bendable region 01 of the display screen 400 is typically at a higher risk of damage during user use, and protecting the bendable region 01 is crucial for extending the lifespan of the display screen 400.

[0081] In view of this, an electronic device is provided in an embodiment of the present application. Figure 4 A cross-sectional view of an electronic device in a folded state provided by an embodiment of the present invention, referring to Figure 4The hinge mechanism 300 of the electronic device provided by the embodiment of the present invention includes a first shielding member 500. When the electronic device is folded inward and is in a folded state, the first shell 100 and the second shell 200 are stacked, the bendable area 01 of the display screen 400 is bent to form a smooth curved surface, the first avoidance opening 02 and the second avoidance opening 03 form an avoidance space, the axial end of the bendable area 01 is accommodated in the avoidance space, and the first shielding member 500 covers at least a portion of the axial end surface of the bendable area 01, thereby protecting the axial end surface of the bendable area 01 from damage, thereby extending the service life of the display screen 400.

[0082] Figure 5 A partial cross-sectional view of an electronic device is provided for an embodiment of the present invention, such as Figure 5 As shown, the display screen 400 includes a stacked protective film layer 410 and a display screen body 420. The protective film layer 410 is located on the display surface O5 side of the display screen body 420. Along the axial direction D1 of the hinge mechanism 300, the protective film layer 410 includes a first extension portion 411. The axial spacing X1 between the first extension portion 411 and the first shielding member 500 is less than the axial spacing X2 between the display screen body 420 and the first shielding member 500. In other words, the first extension portion 411 extends beyond the edge of the display screen body 420. Therefore, the first extension portion 411 can block the axial gap between the edge of the display screen body 420 and the first shielding member 500. This not only improves the aesthetics but also prevents dust and liquids from entering the interior of the display screen 400 through this gap. Furthermore, the first extension portion 411 also serves to protect the display screen body 420.

[0083] Continue to refer to Figure 5 Along the axial direction D1 of the hinge mechanism 300, the axial spacing X1 between the first shielding member 500 and the edge of the first extension 411 proximate to the first shielding member 500 is greater than zero to prevent interference between the first shielding member 500 and the first extension 411. Optionally, X1 may be 0.15 mm ≤ X1 ≤ 0.35 mm. The value of X1 is set based on actual conditions to ensure that the first extension 411 covers as much of the axial gap between the edge of the display screen body 420 proximate to the first shielding member 500 as possible, while also preventing interference between the first extension 411 and the first housing 100 or the second housing 200.

[0084] Figure 6 for Figure 5 Please refer to the bb cross-section of the structure shown. Figure 5 and Figure 6Along the axial direction of the hinge mechanism 300 , the axial spacing X3 between the edge of the first extension portion 411 located at the same end and the edge of the display screen body 420 is 0.1mm≤X3≤0.25mm, so that the first extension portion 411 can protect the edge of the display screen body 420.

[0085] Figure 7 A schematic diagram of a partial structure of an electronic device in a flattened state provided by an embodiment of the present invention, with reference to Figure 7 When the electronic device is in a flattened state, the first shielding member 500 is accommodated within the accommodation space 04 formed by the first avoidance opening 02 and the second avoidance opening 03. The first extension 411 is spaced from the inner wall of the first avoidance opening 02, thereby preventing interference between the first extension 411 and the first housing 100. Optionally, when the electronic device is in a flattened state, the minimum distance x4 between the first extension 411 and the inner wall of the first avoidance opening 02 is 0.15 mm ≤ x4 ≤ 0.30 mm. For example, x4 can be 0.15 mm, 0.16 mm, 0.18 mm, 0.20 mm, 0.23 mm, 0.26 mm, 0.30 mm, or any other value between 0.15 and 0.30 mm.

[0086] In addition, a distance is provided between the first extension portion 411 and the inner wall of the second avoidance opening 03 to prevent the first extension portion 411 from interfering with the second housing 200. Optionally, a minimum distance y4 between the first extension portion 411 and the inner wall of the second avoidance opening 03 is 0.15 mm ≤ y4 ≤ 0.30 mm. For example, y4 can be 0.15 mm, 0.16 mm, 0.18 mm, 0.20 mm, 0.23 mm, 0.26 mm, 0.30 mm, or any other value between 0.15 and 0.30 mm.

[0087] It can be understood that the values ​​of x4 and y4 are set according to actual conditions to take into account the effect of the first extension portion 411 shielding the axial gap between the edge of the display screen body 420 and the first shielding member 500 and avoiding interference between the first extension portion 411 and the first shell 100 or the second shell 200.

[0088] in, Figure 7 The partial structure diagram of the electronic equipment on display is Figure 1 The partial enlarged view of the structure in the dotted box at A of the electronic device in FIG. Figure 7 The specific structure of the electronic equipment is not the same as Figure 1 The structures of the electronic devices shown are exactly the same, and the purpose is only to illustrate which area of ​​the electronic device the partial structural diagram is intended to show. Figure 7The partial structural diagram shown is mainly for illustrating the coordination relationship among the display screen, the first shell, the second shell and the first shielding member.

[0089] Continue to refer to Figure 7 The first extension 411 is provided with a first chamfer 411a and a second chamfer 411b. The first chamfer 411a faces the inner wall of the first avoidance opening 02 of the first shell 100 to prevent the first extension 411 from interfering with the first shell 100. The second chamfer 411b faces the inner wall of the second avoidance opening 03 of the second shell 200 to prevent the second extension 421a from interfering with the second shell 200. Both the first chamfer 411a and the second chamfer 411b may be curved chamfers to reduce edge sharpness and reduce stress concentration. Similarly, the end of the inner wall of the first avoidance opening 02 near the first chamfer 411a includes a curved chamfer to avoid the first chamfer 411a, thereby preventing the first extension 411 from interfering with the first shell 100. An end portion of the inner wall of the second avoiding opening 03 close to the second chamfer 411 b includes an arc-shaped chamfer to avoid the second chamfer 411 b , thereby preventing the second extending portion 421 a from interfering with the second housing 200 .

[0090] Figure 8 This is a structural diagram of an integrally formed rotating shaft and a first shielding member provided in an embodiment of the present invention, referring to Figure 8 The rotating shaft mechanism 300 includes a rotating shaft 310. The rotating shaft 310 and the first shielding member 500 are an integrally formed structure. The two are fixed by snapping, gluing, etc. The rotating shaft mechanism 300 is not only simple in structure and does not require assembly, but also helps to improve the overall drop strength and ensure the reliability of the structure.

[0091] The present invention does not limit the specific shape of the first shielding member 500, as long as it can shield the axial end surface of the bendable area of ​​the display screen. Figure 8 As shown, the first shielding member 500 can be a T-shaped structural member, which includes a shielding portion 510 and a support portion 520 connected to the shielding portion 510. The end of the support portion 520 away from the shielding portion 510 is connected to the rotating shaft 310. The orthographic projection of the shielding portion 510 on the plane where the axial end surface of the bendable region 01 lies covers at least a portion of the axial end surface of the bendable region 01, thereby protecting the axial end surface of the bendable region 01. Optionally, the corners of the shielding portion 510 are all curved chamfers to prevent scratches between the shielding portion 510 and other components.

[0092] Figure 9 A cross-sectional view of a display screen provided by an embodiment of the present invention, referring to Figure 9In the embodiment of the present invention, the display screen body 420 of the electronic device includes a stacked cover layer 421 and a functional laminate 422. The cover layer 421 is disposed between the functional laminate 422 and the protective film layer 410. Along the axial direction D1, the end of the cover layer 421 includes a second extension portion 421a. The axial spacing between the second extension portion 421a and the first shielding member 500 is smaller than the axial spacing between the functional laminate 422 and the first shielding member 500. In other words, the second extension portion 421a is located outside the edge of the functional laminate 422, thereby protecting the edge of the functional laminate 422.

[0093] Furthermore, in the present invention, the simultaneous outward expansion of the cover layer 421 and the protective film layer 410 effectively enhances the rigidity of the display screen 400 and strengthens the shielding and protection of the edges of the functional stack 422, preventing bumps or damage to the functional stack 422. Specifically, along the axial direction of the hinge mechanism 300, the axial spacing X5 between the edge of the second extension portion 421a and the edge of the functional stack 422 at the same end is 0.2 mm ≤ X5 ≤ 0.4 mm, ensuring that the second extension portion 421a has a suitable size.

[0094] Continue to refer to Figure 9 When the cover layer 421 and the protective film layer 410 expand outward at the same time, along the axial direction D1, the axial spacing X6 between the edge of the first extension portion 411 and the edge of the second extension portion 421a located at the same end satisfies 0≤X6≤0.1mm, so that the protective film layer 410 plays a role in protecting the cover layer 421 and preventing the edge of the cover layer 421 from being exposed.

[0095] Optionally, the display screen body 420 further includes a support layer 424 , which is disposed on a side of the functional stack 422 facing away from the cover layer 421 . The support layer 424 serves to support the functional stack 422 and the cover layer 421 .

[0096] Figure 10 A schematic diagram of a partial structure of an electronic device in a flattened state provided by an embodiment of the present invention, with reference to Figure 10 The axial spacing between the second extension portion 421a and the shielding portion 510 of the first shielding member 500 is greater than zero to prevent interference between the shielding portion 510 and the second extension portion 421a. Optionally, along the first direction D2, the second extension portion 421a is larger than the size of the accommodating space 04, so that the second extension portion 421a can shield as much of the accommodating space 04 as possible. The first direction D2 is the direction in which the first and second housings are arranged when the electronic device is in a flattened state.

[0097] Figure 11 A cross-sectional view of a display screen provided in another embodiment of the present invention, referring to Figure 11The functional stack 422 includes multiple film layers, and each film layer has different functions, so that the entire functional stack 422 has multiple functions. It is understandable that the present invention does not limit the number and composition of the film layers of the functional stack 422, and can be set according to actual needs. For example, Figure 11 As shown, from the direction of the protective film layer 410 pointing to the support layer 424, the functional stack 422 can include an optical adhesive layer 422a, an optical compensation layer 422b, a screen function effective layer 422c, a back support film 422d, and a buffer composite tape layer 422e in sequence.

[0098] Figure 12 A cross-sectional view of a display screen provided in another embodiment of the present invention is shown. Figure 13 This is a partial cross-sectional view of an electronic device provided in another embodiment of the present invention. Please refer to Figure 12 and Figure 13 Along the axial direction D1, a protective structural layer 600 is provided on the end surface of the functional stack 422 facing the receiving space 04 and the surface of the second extension 421a facing away from the protective film layer 410 to enhance the strength and rigidity of the edge of the display screen body 420. Furthermore, the protective structural layer 600 ensures good sealing between the cover layer 421 and the functional stack 422, as well as within the functional stack 422 itself, thereby effectively preventing or reducing the ingress of dust or liquid into the interior of the display screen 400. Optionally, the protective structural layer 600 can be fabricated by dispensing adhesive. For example, adhesive is applied to the end surface of the functional stack 422 facing the receiving space 04 and the surface of the second extension 421a facing away from the protective film layer 410 to form a continuous protective layer. This not only ensures a firm bond between the second extension 421a and the functional stack 422, but also acts as a buffer to protect the functional stack 422 from direct impact from external forces, further enhancing the structural reliability of the display screen 400.

[0099] It is understandable that if Figure 12 As shown, when the adhesive is applied to the end face of the functional stack 422 facing the accommodating space 04, in order to ensure that the protective structure layer 600 completely covers the above-mentioned end face, the adhesive applied to the above-mentioned end face diffuses from the functional stack 422 to the end face of the support layer 424 facing the accommodating space 04. Optionally, the adhesive further diffuses to the surface of the support layer 424 facing away from the functional stack 422, and the dimension z1 of the end of the protective structure layer 600 away from the cover layer 421 along the axial direction D1 is less than or equal to 2 mm, so as to fully protect the edge of the functional stack 422.

[0100] In order to ensure that the adhesive completely covers the surface of the second extension portion 421a facing away from the protective film layer 410, when the adhesive is applied to the above-mentioned surface, the adhesive diffuses from the surface of the second extension portion 421a facing away from the protective film layer 410 to the end face of the second extension portion 421a facing the accommodating space 04, and the dimension z2 of the adhesive diffused to the end face of the second extension portion 421a facing the accommodating space 04 along the axial direction D1 is less than or equal to 0.1 mm, so as to avoid excessive adhesive overflow affecting the appearance of the display screen 400.

[0101] Along the first direction D2, the size of the protective structural layer 600 formed by the adhesive must be equal to or larger than the size of the bendable region 01. This allows the protective structural layer 600 to completely cover the exposed axial end surface of the bendable region 01, thereby enhancing its structural strength and protecting it from damage. The first direction is the alignment direction of the first housing 100 and the second housing 200 when the display screen 400 is in the unfolded state.

[0102] Figure 14 A cross-sectional view of a display screen provided in another embodiment of the present invention is shown in FIG. Figure 14 The display screen body 420 also includes a flexible protective layer 423, which is located between the cover layer 421 and the functional stack 422. The flexible protective layer 423 can be an ultra-thin flexible glass (UTG) layer, a polyimide layer, a polyethylene terephthalate layer, an aramid or other transparent film. Along the axial direction D1, the second extension 421a of the cover layer 421 is located outside the edge of the flexible protective layer 423, that is, the axial spacing between the second extension 421a and the first shielding member is smaller than the axial spacing between the flexible protective layer 423 and the first shielding member 500. The second extension 421a can play a role in protecting the edge of the flexible protective layer 423. Optionally, the axial spacing X7 between the edge of the second extension 421a located at the same end and the edge of the flexible protective layer 423 is 0.2mm≤X7≤0.4mm.

[0103] In addition, along the axial direction D1, the size of the flexible protective layer 423 can be smaller than the cover layer 421 and the functional stack 422, that is, a groove is formed between the cover layer 421, the flexible protective layer 423 and the functional stack 422, and the groove is filled with adhesive to further protect the flexible protective layer 423.

[0104] Figure 15 A schematic diagram of a partial structure of an electronic device in a flattened state is provided for another embodiment of the present invention, referring to Figure 15The electronic device of the present invention further includes a second shielding member 700 connected to the first shielding member 500. The second shielding member 700 includes a shielding unit 710. The shielding unit 710 extends from the shielding portion 511 of the first shielding member 500 toward the display screen 400. Along the stacking direction of the display screens 400, the projection of the shielding unit 710 covers at least a portion of the projection of the gap between the first extension portion 411 and the first shielding member 500. The second shielding member 700 can block the axial gap between the display screen 400 and the first shielding member 500, preventing dust, liquid, etc. from entering the electronic device through the gap and preventing the risk of being snagged or damaged.

[0105] Optionally, the first shielding member 500 and the second shielding member 700 are not an integrally formed structure. The second shielding member 700 can be installed after the display screen 400, the first shielding member 500 and the hinge mechanism 300 are assembled. This ensures that the gap between the display screen 400 and the shielding portion 510 of the first shielding member 500 remains unchanged, which helps to achieve a narrow-frame design for the electronic device.

[0106] Figure 16 A cross-sectional view of an electronic device in a folded state provided in another embodiment of the present invention can be referred to in conjunction with Figure 15 and Figure 16 , along the first direction D2, the size m of the shielding unit 710 is less than or equal to 3 mm, optionally, m is less than or equal to about 1 mm. In this way, when the electronic device is in the folded state, the bendable area 01 of the folding screen forms a smooth curved surface structure, and the second shielding member 700 is located within the space formed by the above-mentioned curved surface, and can also prevent the shielding unit 710 from interfering with the display screen 400, the first shell 100 or the second shell 200.

[0107] Figure 17 A partial cross-sectional view of an electronic device provided in another embodiment of the present invention, referring to Figure 17 The second shielding member 700 further includes a connecting member 720, through which the shielding unit 710 is connected to the first shielding member 500. The connecting member 720 extends along the stacking direction D3 of the display screen 400. Optionally, along the stacking direction D3, a minimum distance X8 between the shielding unit 710 and the display screen 400 is greater than or equal to 0.25 mm to prevent interference between the shielding unit 710 and the display screen 400.

[0108] In the present invention, the shielding unit 710 can be a mounting plate parallel to the display screen 400, with the connector 720 connected to the surface of the shielding unit 710 facing the display screen 400. Along the stacking direction D3 of the display screen 400, the thickness e of the shielding unit 710 is ≥ 0.15 mm. If the thickness of the shielding unit 710 is too thin, its hardness may be reduced. Optionally, along the stacking direction D3, the projection of the shielding unit 710 overlaps at least a portion of the projection of the display screen 400, and along the axial direction D1, the dimension g of the overlapping portion between the projection of the shielding unit 710 and the projection of the display screen 400 is ≥ 0.15 mm.

[0109] In one possible embodiment, to ensure a secure connection between the connector 720 and the first shielding member 500, the connector 720 and the first shielding member 500 are riveted together. To achieve this, the first shielding member 500 and the second shielding member 700 have specific shapes and structures, which are described in detail below with reference to the accompanying drawings.

[0110] Figure 18 This is a schematic diagram of the structure of the second shielding member provided in an embodiment of the present invention, referring to Figure 18 The end of the connecting member 720 of the second shielding member 700 away from the shielding unit 710 includes a serrated portion 730, and the serrated portion 730 includes a plurality of tooth-like structures 731, and the plurality of tooth-like structures 731 are evenly distributed along the circumference of the connecting member 720, and any two adjacent tooth-like structures 731 are spaced apart, one end of the tooth structure 731 is connected to the end of the connecting member 720 away from the shielding unit 710, and the other end of the tooth structure 731 extends toward the shielding unit 710 and away from the connecting member 720, wherein the end of the tooth structure 731 close to the shielding unit 710 is the tooth top 731a, and there is a gap between the tooth top 731a and the connecting member 720.

[0111] Figure 19 A cross-sectional view of a second shielding member provided in an embodiment of the present invention, referring to Figure 19 Along the axial direction D1, the dimension of the end of the connecting member 720 away from the shielding unit 710 is I, the radial distance between the tooth tops 731a of the two farthest tooth-like structures 731 and the wall surface away from the connecting member 720 is J, and the dimension H of the radial gap between the tooth tops 731a and the connecting member 720 is between 0.1-0.2mm.

[0112] In order to make the first shielding member 500 cooperate with the connecting member 720 having the serrated portion 730, continue to refer to Figure 17The end of the first shielding member 500 facing the second shielding member 700 is provided with a mounting groove 06. Specifically, the inner wall of the mounting groove 06 is provided with a stepped structure, wherein the inner diameter d of the portion of the mounting groove 06 near the groove opening is smaller than the inner diameter b of the portion of the mounting groove 06 near the groove bottom. Thus, when the connecting member 720 enters the mounting groove 06, the tooth tips 731a of the serrations 730 abut against the stepped structure, preventing the connecting member 720 from falling out of the mounting groove 06 under vibration conditions, thereby effectively improving the reliability of the connection between the two.

[0113] You can continue to refer to Figure 17 , along the stacking direction D3 of the display screen 400, the radial dimension k of the end face of the step structure is greater than or equal to 0.1 mm to ensure that the tooth top 731a can abut the end face of the step structure. It can be understood that I≤d, J≤b, so that the connecting member 720 can smoothly enter the installation groove 06. Optionally, b≥0.4mm, d≥0.2mm. Among them, along the axial direction D1, the dimension a of the wall of the installation groove 06 close to the bottom of the groove away from the display screen 400, and the dimension c of the wall close to the display screen 400 are both greater than or equal to 0.15 mm, and a+b+c≤0.8mm.

[0114] Figure 20 A top view of the second shielding member provided in one embodiment of the present invention, referring to Figure 20 The shielding unit 710 of the second shielding member 700 is a single-piece structure, and the corners of the shielding unit 710 facing the display screen 400 are provided with arc chamfers to avoid interference with other components. The shielding unit 710 and the connecting member 720 can be an integrally formed structure, or they can be fixedly connected by welding or other methods.

[0115] Figure 21 This is a structural diagram of the mounting surface of the first shielding member and the second shielding member of an electronic device provided by an embodiment of the present invention, with reference to Figure 21 The end surface of the first shielding member 500 facing the second shielding member 700 is the mounting surface 07, and the mounting surface 07 is coated with adhesive 740 to ensure a tight connection between the second shielding member 700 and the mounting surface 07, thereby further improving the connection strength between the second shielding member 700 and the first shielding member 500, thereby preventing the second shielding member 700 from shaking and falling off.

[0116] Optionally, the second shielding member has a strength greater than or equal to 1800 MPa, wherein the second shielding member may be made of spring steel, etc. Spring steel generally has a high elastic limit and good toughness, can resist impact and vibration, thereby protecting the display screen and extending its service life.

[0117] Based on the same technical concept, an embodiment of the present invention also provides another electronic device to effectively protect the exposed axial end surface of the bendable area of ​​the display screen. Figure 22 This is a partial structural diagram of an electronic device in a flattened state according to an embodiment of the present invention, referring to Figure 22 The electronic device includes a first housing 100, a second housing 200, a hinge mechanism 300, and a display screen 400. The first housing 100 and the second housing 200 are respectively arranged on opposite sides of the hinge mechanism 300. The first housing 100 and the second housing 200 are rotatably connected by the hinge mechanism 300 to enable the electronic device to be folded or unfolded. The display screen 400 continuously covers the first housing 100, the hinge mechanism 300, and the second housing 200. The display screen 400 includes a bendable area 01, which covers the hinge mechanism 300. Along the axial direction D1 of the hinge mechanism 300, the end of the first housing 100 includes a first avoidance opening 02, and the end of the second housing 200 includes a second avoidance opening 03. When the electronic device is in a flattened state, the first avoidance opening 02 and the second avoidance opening 03 located at the same end of the electronic device along the axial direction form a storage space 04. The hinge mechanism 300 includes a first shielding member 500, which is accommodated in the accommodating space 04. The first shielding member 500 covers at least a portion of the axial end surface of the bendable area 01, thereby protecting the axial end surface of the bendable area 01 from damage and extending the service life of the display screen 400.

[0118] In a possible embodiment of the present invention, the first shielding member 500 and the rotating shaft 310 of the rotating shaft mechanism 300 may be an integrally formed structure to improve the structural reliability of the rotating shaft mechanism 300 .

[0119] Continue to refer to Figure 22 The electronic device further includes a third shielding member 800, which is accommodated in the accommodation space 04. One end of the third shielding member 800 is connected to the first housing 100, and the other end of the third shielding member 800 is slidably connected to the second housing 200. Along the stacking direction of the display screen 400, the projection of the third shielding member 800 covers at least a portion of the projection of the gap between the first shielding member 500 and the display screen 400. The third shielding member 800 serves to shield the axial gap between the first shielding member 500 and the display screen 400, preventing foreign matter from entering the interior of the electronic device through this gap, and also protects the edges of the display screen 400.

[0120] It will be appreciated that, along the first direction D2, one end of the third shielding member 800 is fixedly or slidably connected to the first housing 100, while the other end of the third shielding member 800 is slidably connected to the second housing 200. This facilitates bending and deformation of the third shielding member 800 when the electronic device is folded. Furthermore, there is no connection between the third shielding member 800 and the first shielding member 500, facilitating the free bending of the third shielding member 800.

[0121] The third shielding member 800 and the first housing 100 may be fixedly connected by means of clamping, welding, etc. For example, Figure 23 This is a schematic structural diagram of a third shielding member provided in one embodiment of the present utility model. Figure 24 A partial structural diagram of the second housing provided in an embodiment of the present invention, referring to Figure 23 and Figure 24 The third shielding member 800 is connected to the first housing 100 via a clamping assembly 820. The clamping assembly 820 includes a clamping groove 821 and a clamping protrusion 822 that cooperates with the clamping groove 821. In a possible implementation, as shown in FIG. Figure 23 As shown, the engaging groove 821 is provided on the surface of the third shielding member 800 facing the first housing 100, as shown in FIG. Figure 24 As shown, the engaging protrusion 822 is provided on the surface of the first housing 100 facing the third shielding member 800. In another possible implementation, the engaging groove 821 is provided on the surface of the first housing 100 facing the third shielding member 800, and the engaging protrusion 822 is provided on the surface of the third shielding member 800 facing the first housing 100. To further enhance the secure connection between the third shielding member 800 and the first housing 100, adhesive may be applied to the contact surfaces thereof.

[0122] Reference Figure 23 and Figure 25 , Figure 25 This is a partial structural diagram of the first shell provided by an embodiment of the present utility model. Figure 23 The third shielding member 800 is slidably connected to the second housing 200 via a sliding assembly 830. The sliding assembly 830 includes a sliding groove 831 and a slider 832 that cooperates with the sliding groove 831. In a possible implementation, as Figure 23 As shown, the slider 832 is provided on the surface of the third shielding member 800 facing the second housing 200, as shown in FIG. Figure 25 As shown, the slide groove 831 is provided on the surface of the second housing 200 facing the third shielding member 800. In another possible implementation, the slider 832 is provided on the surface of the second housing 200 facing the third shielding member 800, and the slide groove 831 is provided on the surface of the third shielding member 800 facing the second housing 200.

[0123] Figure 26This is a schematic structural diagram of a third shielding member provided in another embodiment of the present invention, referring to Figure 26 The third shielding member 800 has a folding area that can bend or unfold around the axis of the hinge mechanism 300. The folding area is provided with openings 08. When the third shielding member 800 is bent, the openings 08 disperse stress, preventing stress concentration in the folding area, thereby reducing or preventing cracks or breakage in the folding area during bending. Optionally, the openings 08 extend through the third shielding member 800 along the stacking direction of the display screen 400 to enhance its fatigue resistance. The number of openings 08 can be one, two, or more, depending on actual needs.

[0124] Figure 27 A schematic structural diagram of a third shielding member provided in another embodiment of the present invention, referring to Figure 27 The surface of the third shielding member 800 is provided with a covering layer 810. This covering layer 810 covers at least the opening 08 to enhance the aesthetics and prevent the opening 08 from scratching the display screen 400. The covering layer 810 is made of at least one of a polyester film and a thermoplastic urethane (TPU). Both polyester film and TPU have excellent elasticity, toughness, and wear resistance, and can maintain good mechanical properties even after repeated bending.

[0125] Optionally, the thickness of the third shielding member along the display screen stacking direction is 0.02-0.03mm to minimize the overall thickness of the electronic device. Furthermore, the third shielding member should have a strength of 1500 MPa or greater, and the strength should be uniform throughout the member, with no weak spots, to ensure overall strength and prevent breakage during repeated folding. The third shielding member can be a stainless steel sheet. Optionally, the third shielding member can be integrally formed, such as from a continuous steel sheet, to facilitate smoother bending and deformation.

The shape and structure of the second extension portion can be referred to the description of the shape and structure of the second extension portion in the various possible embodiments of the present invention, and will not be repeated here.

[0129] In order to extend the bendable areas of the protective film layer and the cover layer, the present invention may adopt a secondary cutting process to process the display screen, which will be described in detail below with reference to the accompanying drawings.

[0130] Figure 30 A schematic diagram of a cutting path of a display screen provided by an embodiment of the present invention, referring to Figure 30 When cutting the display screen 400, the invalid area at the edge of the display screen 400 can be enlarged.

[0131] The secondary cutting process includes the following steps:

[0132] Step 1), such as Figure 31 As shown, when cutting the functional stack 422 (e.g., an OLED device), the cutting can be performed along the first cutting line 10 (dashed line in the figure) so that the bendable region 01 of the functional stack 422 after cutting forms a concave region, that is, the axial dimension of the bendable region 01 of the functional stack 422 is smaller than the axial dimensions of other regions of the functional stack 422, thereby obtaining the cut functional stack 422;

[0133] Step 2), the cover layer 421 is covered on the surface of the cut functional stack 422 obtained in step 1), such as Figure 32 As shown, the cover layer 421 and the functional stack 422 are then cut integrally along the second cutting line 20, for example, by laser cutting, to obtain the cut display body 420. At this time, the second extension 421a of the cover layer 421 is formed, and the axial distance between the edge of the second extension 421a at the same end and the edge of the functional stack 422 is X5, which can be referred to Figure 33 As shown, along the axial direction, the axial spacing X5 between the edge of the second extension portion 421a and the edge of the functional stack 422 located at the same end is 0.2mm≤X5≤0.4mm;

[0134] Step 3), the protective film layer 410 is placed on the surface of the display screen body 420 obtained after cutting in step 2), and the cover layer 421 is located between the protective film layer 410 and the functional stack 422, as shown in FIG. Figure 34 As shown, along the axial direction, the protective film layer 410 includes a first extension portion 411 , and the axial distance between the edge of the first extension portion 411 and the edge of the functional stack 422 at the same end is X3, wherein 0.1 mm≤X3≤0.25 mm.

[0135] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
