For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances. When it is described that a specific device is located between the first device and the second device, there can be or can not be an intermediate device between the specific device and the first device or the second device.

[0053] All terms used in the present disclosure have the same meaning as understood by those skilled in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted to have meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or excessively formalized sense, unless specifically defined here.

[0054] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered as part of the specification.

[0055] With the advancement of foldable screen and hinge technology, there are more and more foldable terminal products on the market, such as smartphones and tablets. In order to ensure that the hinge can rotate flexibly, these devices usually reserve a certain movement gap between the hinge and the shell on both sides of the hinge. However, this design is easy for external particulate foreign matter to enter the inside of the hinge through these gaps, causing the hinge to operate smoothly or be damaged, affecting the user experience.

[0056] The existing dustproof piece is a long strip brush arranged on the horizontal surface or vertical surface of the inner wall or outer wall of the electronic device shell. However, in order to meet the user's comfort and the product's appearance, the connection between the horizontal surface and the vertical surface of the shell is usually set as a circular arc, and the inner and outer surfaces of the shell form a curved surface, so that the product appearance is round and comfortable to hold with the hand.

[0057] However, the long dustproof piece cannot be bent along the shape when being attached to the shell, is easy to loosen and fall off, and affects the user's experience. Therefore, when the shell has a bending part, especially the gap corresponding to the bending part, the existing dustproof measures cannot completely eliminate these gaps, and a new solution is needed to overcome the above problems.

[0058] The present disclosure provides a shell, referring to Figures 1-4 As shown, it comprises a shell surface 10 and a dustproof part 20.

[0059] The shell surface 10 comprises a first surface 11, a second surface 12, and a target surface 13 formed between the first surface 11 and the second surface 12, for connecting and forming an included angle between the first surface 11 and the second surface 12.

[0060] The dustproof part 20 is arranged on the shell surface 10.

[0061] The dustproof part 20 is arranged on the target surface 13 at least, so as to increase the thickness of the target surface 13, thereby reducing or eliminating the gap between the components arranged opposite and spaced apart from the target surface 13.

[0062] It can be understood that the shell can be a protective shell of the main body on both sides of the folding electronic device rotating shaft. The protective shell can be a shell held by the user or placed on a bearing surface. The bearing surface can be a surface with a bearing function such as a table. The outer side wall of the shell is in contact with the user's hand for holding or in contact with the bearing surface for placing and supporting the electronic device.

[0063] At this time, the corresponding shell surface 10 is the inner side wall surface of the protective shell facing the inside of the electronic device. The first surface 11 can be a horizontal inner wall facing the inside of the electronic device. The second surface 12 can be an inclined surface at an angle to the first surface 11. The angle can be above 90° and not greater than 180° or other ranges. The present disclosure does not limit this. When the angle is 90°, the second surface 12 is a vertical inner wall of the protective shell.

[0064] The target surface 13 can be the part connecting the first surface 11 and the second surface 12, which can be an arc-shaped transition area for forming an included angle between the two surfaces. The target surface 13 is a transition inner side wall of the first surface 11 and the second surface 12 facing the inside of the electronic device.

[0065] The dustproof part 20 is arranged on the target surface 13 at least, so as to increase the thickness of the arc-shaped transition area, so as to fill the gap of the protective shell of the electronic device, thereby achieving the effect of reducing or eliminating the gap of the transition area of the electronic device. The components arranged opposite and spaced apart from the target surface 13 can be a rotating shaft assembly or a rotating shaft protective shell.

[0066] The shell can also be understood as a hinge protection shell at the hinge of the folding electronic device. The hinge protection shell can be a protective shell arranged at the hinge, used to protect the hinge mechanism, providing the first line of defense for the internal precise hinge mechanism, preventing external impact, collision or accidental force from directly acting on the hinge, thereby reducing the risk of mechanical damage. The hinge protection shell can also effectively prevent dust, sand particles, liquids and other external pollutants from entering the hinge, avoiding malfunctions caused by foreign objects getting stuck or corrosion.

[0067] At this time, the shell surface 10 can be the part of the hinge protection shell overlapping with the electronic device protective shell in the closed state of the electronic device. The first surface 11 is the horizontal outer wall of the hinge protection shell facing the horizontal inner wall of the electronic device protective shell. The second surface 12 can be an inclined surface at an angle to the first surface 11.

[0068] The target surface 13 can be the part connecting the first surface 11 and the second surface 12, which can be an arc-shaped transition area, used to form an included angle between the two surfaces. The target surface 13 is the transition outer side wall of the first surface 11 and the second surface 12 facing the outside of the electronic device.

[0069] The dustproof part 20 is arranged at least on the target surface 13, used to increase the thickness of the arc-shaped transition area, to fill the gap of the hinge protection shell, thereby achieving the effect of reducing or eliminating the gap in the transition area of the electronic device. The component arranged at a relative interval with the target surface 13 can be the protective shell of the electronic device.

[0070] In the case where the dustproof part 20 is arranged on the inner side wall surface of the protective shell, a soft and non-static adsorption material such as flexible plastic or elastic fabric can be selected to avoid interference with the internal components of the device. In order not to affect the use efficiency of the internal space of the device, the dustproof part 20 can be designed in a pasting or embedding mode, directly attached to the target surface 13.

[0071] In the case where the dustproof part 20 is arranged on the outer side wall surface of the hinge protection shell, the dustproof part 20 not only needs to have good dustproof performance, but also needs to have certain aesthetic and durability. Therefore, high-strength and wear-resistant materials such as polyurethane (PU) or thermoplastic elastomer (TPE) can be selected, which are both flexible and scratch-resistant. The dustproof part 20 can be fixed on the outer side of the hinge protection shell in a pasting, buckling or other fixing mode to ensure its stability and easy replacement characteristics.

[0072] The target surface 13 is provided with the dustproof part 20 to solve the problem of the gap at the bending part of the shell. Not only can it effectively improve the dustproof ability of the product and prolong the service life, but also can optimize the internal space layout and improve the compactness and aesthetics of the overall design.

[0073] In some embodiments, referring to Figure 5As shown, the dustproof part 20 also extends to the first surface 11 and the second surface 12 to increase the thickness of the housing surface 10, thereby reducing or eliminating the gap between the housing surface 10 and the components arranged opposite and spaced apart from the housing surface 10.

[0074] As can be understood, in order to further enhance the dustproof performance of the housing and ensure that the gap between the housing and adjacent components is as small as possible or eliminated, the dustproof part 20 is not only arranged on the target surface 13, but also extends to the first surface 11 and the second surface 12. The overall thickness of the housing surface can be increased to effectively seal the entire area.

[0075] The dustproof part 20 can be arranged continuously and integrally, with the target surface 13 extending to the first surface 11 and the second surface 12, or can be arranged separately on the target surface 13, the first surface 11 and the second surface 12. The two ends of the dustproof part 20 arranged on the target surface 13 are respectively connected to the dustproof part 20 of the first surface 11 and the second surface 12.

[0076] The dustproof part 20 can be directly adhered to the housing surface 10 by high-strength adhesive to ensure firm fixation and prevent it from falling off.

[0077] In the case of regular maintenance or cleaning, the dustproof part 20 can also be arranged in a detachable form, such as using buckles, magnetic attraction or special tools for quick installation and removal, to facilitate disassembly and maintenance by users or technicians.

[0078] In some embodiments, referring to Figure 6 As shown, the dustproof part 20 includes a bonding layer 21 and a dustproof layer 22. The bonding layer 21 is arranged on the housing surface 10, and the dustproof layer 22 is arranged on the bonding layer 21. The dustproof layer 22 has a certain thickness to fill the gap.

[0079] As can be understood, in order to improve the stability of the dustproof part 20 arranged on the housing and provide good dustproof effect, the dustproof part 20 includes a bonding layer 21 and a dustproof layer 22.

[0080] The bonding layer 21 is used to firmly fix the dustproof layer 22 on the housing surface 10, ensuring that the dustproof part 20 will not fall off due to vibration or impact in daily use. The bonding layer 21 can be a high-strength adhesive with good adhesion to various materials such as metal and plastic, such as epoxy resin, polyurethane glue or acrylic glue. These adhesives not only have strong adhesion, but also have weather resistance and anti-aging properties, and can maintain stable performance for a long time.

[0081] The bonding layer 21 can also be a double-sided tape, such as a 3M VHB tape. Such tapes have excellent adhesion strength and flexibility, and are suitable for situations that require quick installation and long-term stability.

[0082] The thickness of the adhesive layer 21 should be as thin as possible to reduce the impact on the overall thickness of the device, while ensuring sufficient bonding strength.

[0083] Among them, the dustproof layer 22 is the core part of the dustproof part 20, which is responsible for directly blocking dust, moisture and other small particles from entering the inside of the rotating shaft. It needs to have a certain thickness to fill the gap between the shell surface 10 and the adjacent components, and maintain flexibility to adapt to the opening and closing action of the device.

[0084] In key positions where larger gaps are prone to occur (such as near the rotating shaft, around the interface, etc.), the thickness of the dustproof layer 22 is appropriately increased to ensure better dustproof sealing in these places.

[0085] A waterproof and breathable film can be added to the dustproof layer 22 to allow air circulation but prevent moisture from entering, further improving protection performance. Considering that users frequently come into contact with it, an antibacterial coating can also be added to the surface of the dustproof layer 22 to prevent bacterial growth and improve hygiene standards.

[0086] The dustproof layer 22 can be directly attached to the shell surface 10 through the adhesive layer 21, ensuring that it is firmly fixed and not easily detached.

[0087] For cases that require regular maintenance or cleaning, the dustproof layer 22 can also be designed to be detachable, such as using buckles, magnetic attraction or special tools for quick installation and removal, making it convenient for users or technicians to perform maintenance.

[0088] In some embodiments, referring to Figure 7 As shown, the thickness of the dustproof layer 22 provided on the first surface 11 changes from one side close to the outer edge of the shell to the other side away from the outer edge of the shell, so that the top of the dustproof layer 22 forms a first target shape 30, which at least includes at least one of a stepped shape, an inclined shape and a circular arc shape.

[0089] It can be understood that, in order to overcome the dust problem caused by the change of the gap when the device is folded, especially when the first body 70 and the second body 80 of the folded electronic device are unfolded at 90 degrees, the gap between the part corresponding to the first surface 11 of the electronic device protective shell and the first surface 11 of the rotating shaft protective shell is the largest, and in the case that the first body 70 and the second body 80 are close to each other, the device is closed, the gap will gradually become smaller. In order to adapt to the situation that the gap changes with the change of the device form, the thickness or height of the dustproof layer 22 changes from one side close to the outer edge of the shell to the other side away from the outer edge of the shell. By changing the thickness or height of the dustproof layer 22, it can dynamically adapt to the gap change under different opening angles of the device.

[0090] The thickness of the dustproof layer 22 can be stepped up or down, forming multiple levels of steps. The height of each step can be adjusted according to actual needs to adapt to the size of the gap at different positions.

[0091] The stepped shape can provide a segmented sealing barrier, effectively preventing dust from entering even in areas with larger gaps.

[0092] The dustproof layer 22 can also be linearly inclined from one side to the other, forming a slope. This can allow the dustproof layer 22 to naturally fill larger gaps when the device is unfolded, and to compress into a thinner state when closed.

[0093] The thickness of the dustproof layer 22 can also vary according to a circular arc curve, forming a soft curved surface. The circular arc shape can better fit irregular gap changes, especially in complex bending areas.

[0094] By setting the thickness of the dustproof layer 22 on the first surface 11 to vary and form a target shape of stepped, inclined, or circular arc shape, the gap problem of the device at different opening angles can be significantly reduced or eliminated, thereby providing better dustproof effect.

[0095] It should be noted that the first target shape 30 in the above several forms can be presented alone or in combination to achieve better dustproof effect.

[0096] In some embodiments, referring to Figure 8 As shown, the shell surface 10 is provided with a groove 50, the length direction of the groove 50 can extend to the first surface 11, the second surface 12 and the target surface 13, and the adhesive layer 21 is placed in the groove 50.

[0097] Specifically, by setting the groove 50 on the shell surface 10 and placing the adhesive layer 21 in the groove 50, the installation stability and dustproof effect of the dustproof part 20 can be further improved, and by placing the adhesive layer 21 in the groove 50, the groove 50 can accommodate the adhesive layer 21, avoiding external dust, debris and other contaminants from adhering to the adhesive layer 21.

[0098] The groove 50 can be provided along the outer side of the shell, and the length direction of the groove 50 can cover the first surface 11, the second surface 12 and the target surface 13; the width of the groove 50 is much smaller than the length of the groove 50, and the width of the groove 50 corresponds to the width of the adhesive layer 21, the depth of the groove 50 is sufficient to accommodate the adhesive layer 21, and the height of the dustproof layer 22 is greater than the depth of the groove 50, so that the dustproof layer 22 extends away from the groove 50 to reduce or eliminate the gap.

[0099] The adhesive layer 21 arranged in the groove 50 not only serves to fix the dustproof layer 22, but also acts as a buffer layer to absorb stress during the opening and closing of the device, thereby reducing wear and tear on the dustproof layer 22.

[0100] The specific implementation is as follows: a groove 50 that meets the requirements is precisely machined on the surface 10 of the shell, ensuring that its shape and size are accurate; the selected adhesive material is evenly applied or placed in the groove 50 to avoid affecting the appearance due to overflow; and the dustproof layer 22 is embedded in the groove 50 to ensure that it is completely fitted and free of bubbles or gaps.

[0101] By placing the adhesive layer 21 in the groove 50 and combining it with the design of the dustproof layer 22 of a specific shape, the installation stability and sealing effect of the dustproof part 20 can be significantly improved. This design not only solves the challenge of changing gaps during device folding, but also enhances the structural stability of the device, improves the user's operation experience, and prolongs the service life of the device.

[0102] In some embodiments, referring to Figure 9 As shown, the depth of the groove 50 arranged on the first surface 11 changes from the side close to the outer edge of the shell to the other side away from the outer edge of the shell, so that the groove bottom of the groove 50 forms a second target shape 40, which includes at least one of a stepped shape, an inclined shape, and a circular arc shape.

[0103] It can be understood that in order to adapt to the situation that the gap changes with the change of the device form as mentioned in the above content.

[0104] The height of the dustproof layer 22 can be constant, and the groove bottom of the groove 50 is set to different depths to form a second target shape 40, so that when the dustproof layer 22 is fitted or fitted on the groove bottom of the groove 50, it presents different heights to meet the dustproof requirements brought by the change of the gap.

[0105] The bottom of the groove 50 can be stepped up or down, forming a plurality of distinct steps. The height of each step can be adjusted according to actual needs, so that the dustproof layer 22 placed in the groove 50 can form a stepped shape; the bottom of the groove 50 can be linearly inclined to form a slope, so that the dustproof layer 22 placed in the groove 50 can form a slope; the bottom of the groove 50 can be in a circular arc shape, so that the bottom of the groove 50 changes according to a circular arc curve, so that the dustproof layer 22 placed in the groove 50 can form a soft curved surface.

[0106] The dustproof layer 22 is embedded in the groove 50, and the thickness change thereof matches the target shape of the bottom of the groove 50, ensuring that it can maintain close fitting and good sealing effect during the entire opening and closing process of the device.

[0107] By setting the groove 50 depth change in the first surface 11, and making the groove 50 bottom forming a stepped, inclined or circular arc-shaped second target shape 40, the installation stability and sealing effect of the dustproof part 20 can be significantly improved

[0108] The forming of the groove 50 bottom can adopt precision machining technology, such as numerical control machine tool (CNC), laser cutting or injection molding, etc., to ensure the accurate size and uniform quality of the groove 50.

[0109] In some embodiments, the dustproof layer 22 includes: a first dustproof layer 22, which is arranged on the adhesive layer 21 and perpendicular to the shell surface 10; or a second dustproof layer 60, which is arranged on the adhesive layer 21 and extends away from the direction of the shell surface 10.

[0110] It can be understood that the first dustproof layer 22 is arranged vertically on the shell surface 10, and the dustproof layer 22 can directly contact and fill the gap to provide a tight dustproof sealing effect. The first dustproof layer 22 can be a dustproof velvet made of polyurethane (PU), polyester or nylon material, which has a high-density fiber structure and can effectively capture tiny particles. It can also be a silicone or thermoplastic elastomer, which has good elasticity and sealing performance and can maintain shape and sealing function at different angles.

[0111] The second dustproof layer 60 is arranged on the adhesive layer 21 and extends away from the direction of the shell surface 10. The second dustproof layer 60 can be a brush formed by nylon, polyester fiber or natural animal hair material, which has high strength, wear resistance and good elasticity. It can also be a flexible rubber or silicone. The filaments on the surface of the brush can naturally shake off the dust attached to them, reducing dust accumulation, and the filaments of the brush can also effectively block larger dust particles or sand from entering the shaft interior, providing a preliminary protective barrier.

[0112] In some embodiments, the first dustproof layer 22 is a dustproof velvet.

[0113] It can be understood that the dustproof velvet is a flocking, and the flocking process includes electrostatic flocking, which uses the principle of static electricity to make the fibers stand vertically and adhere to the substrate coated with adhesive; it also includes water pressure flocking, which uses high-pressure water flow to flush the fibers into the adhesive; and hot melt flocking, which uses thermoplastic material as adhesive to fix the fibers on the substrate under heating conditions.

[0114] The flocking layer forms a layer of dense short fibers that can capture tiny dust particles and prevent them from further entering. After special treatment, the flocking material can have anti-static properties to prevent static electricity from attracting dust, further enhancing the dustproof effect. The material of the flocking can be polyester fiber, nylon fiber, acrylic fiber, natural fiber, etc.

[0115] The flocking layer is directly arranged on the adhesive layer 21 and is fixed in the groove 50 by high-strength adhesive, so as to ensure that the flocking layer is not easy to fall off.

[0116] In some embodiments, referring to Figure 10 The second dustproof layer 60 includes a base layer 61, which is used to be in contact with the adhesive layer 21.

[0117] A plurality of bristles 62 are arranged on the base layer 61 and connected with the base layer 61, and the other end extends away from the base layer 61.

[0118] It can be understood that the second dustproof layer 60 includes the base layer 61 and the bristles, the base layer 61 is the basic part of the second dustproof layer 60, which is used to be in contact with the adhesive layer 21, so as to ensure that the entire dustproof layer 22 can be firmly fixed on the shell surface 10.

[0119] The base layer 61 can be flexible plastic, such as thermoplastic polyurethane (TPU) and thermoplastic elastomer (TPE); it can also be fabric or non-woven fabric, which can provide additional support and cushioning effect, and increase the adhesion performance; it can also be a metal sheet.

[0120] A plurality of bristles 62 are arranged on the base layer 61, one end of which is connected with the base layer 61, and the other end extends away from the base layer 61, so that the bristles 62 can naturally stretch when the device is opened and closed, and the vertical staggered bristles can achieve a certain density to block dust and adapt to different gap changes. The material of the bristles can be nylon and polyester fiber.

[0121] In some embodiments, referring to Figures 11-12 The electronic device includes a first body 70 and a second body 80.

[0122] The first body 70 and the second body 80 are connected by a rotating assembly to change the shape of the electronic device.

[0123] The shell is arranged outside the first body 70, the second body 80 or the rotating assembly, and serves as a protective shell of the electronic device.

[0124] The shell includes a shell surface 10, which includes a first surface 11, a second surface 12 and a target surface 13. The target surface 13 is formed between the first surface 11 and the second surface 12, and is used to connect the first surface 11 and the second surface 12 to form an included angle therebetween.

[0125] The dustproof part 20 is arranged on the shell surface 10.

[0126] The dustproof part 20 is arranged at least on the target surface 13 to increase the thickness of the target surface 13, so as to reduce or eliminate the gap between the component arranged opposite to and spaced from the target surface 13, for blocking foreign matters from entering the inside of the electronic device through the gap.

[0127] It can be understood that the electronic device can be a device with a folding use function, such as a smart phone, a tablet computer, a notebook computer, a smart watch, etc.

[0128] For example, the electronic device is a folding screen mobile phone, the first body 70 can include a part of the display screen and other core components, and the second body 80 can include another part of the display screen and additional input and output interfaces, cameras, etc.

[0129] The rotating assembly (rotation shaft) is used to connect the first body 70 and the second body 80, and can make the electronic device open and close, and the rotation shaft assembly can also support multi-angle parking.

[0130] For example, the shell is a protective shell of the electronic device, and the shell is arranged on the first body 70 and the second body 80 as a protective shell or arranged on the outside of the rotating assembly as a rotation shaft protective shell, which provides physical protection and improves the appearance of the product.

[0131] In the case where the shell is a protective shell of the first body 70 and the second body 80, the shell surface 10 is an inner side surface of the protective shell facing the inside of the electronic device, the first surface 11 is a horizontal plane as an inner bottom wall of the protective shell, the second surface 12 is a vertical plane on both sides of the first surface 11 as an inner side wall of the protective shell, and the target surface 13 is a transition zone formed by connecting the first surface 11 and the second surface 12 to form a slope or an arc. The component arranged opposite to and spaced from the target surface 13 can be a rotation shaft, and can also be a rotation shaft protective shell, at this time, the dustproof part 20 is arranged on the target surface 13 to increase the thickness of the target surface 13, so as to reduce or eliminate the gap between the outer side wall of the rotation shaft protective shell and the inner side wall of the protective shell of the electronic device, and prevent foreign matters from entering the inside of the device from the bending part of the shell.
