Description

Technical Field

[0001] The present application relates to the technical field of electronic device protection, and in particular to a protective cover and a folding device assembly. Background Art

[0002] In the relevant technologies, the durability of the inner screen of foldable electronic devices is the primary pain point that affects users' purchase of foldable electronic devices. With the iterative development of industry technology, the durability of the inner screen of foldable electronic devices is also constantly improving. However, when a foldable electronic device falls from a certain angle, it may still cause problems such as black spots and leakage on the inner screen, which is also the "bottleneck problem" agreed upon by the industry. In particular, when the entire hinge cover of a foldable electronic device falls vertically to the ground, the inner screen is strongly impacted by the hinge, and the flexible screen is easily squeezed and deformed, which may eventually lead to problems such as black spots and leakage on the inner screen.

[0003] In order to improve the drop resistance of foldable electronic devices, protective cases for foldable electronic devices have come into being. General foldable screen protective cases usually consist of two main parts, specifically the main body protection area and the hinge cover protection area. This type of protective cover seems to increase the area of ​​the protection area, but in fact the protection effect on the inner screen is limited. When the whole machine falls perpendicular to the hinge cover surface, the hinge cover protection area first contacts the ground, and the energy of the final fall in the hinge cover protection area will still be transferred to the hinge cover, causing the hinge cover to collapse inward and squeeze the hinge and inner screen. It can be seen that the protective cover in the related art has the problem of poor protection effect on foldable electronic devices. Summary of the Invention

[0004] The embodiments of the present application provide a protective cover and a foldable device assembly, which can solve the problem in the related art that the protective cover has a poor protective effect on the foldable electronic device.

[0005] In a first aspect, a protective cover is provided for a foldable electronic device, wherein the foldable electronic device includes a first body and a second body, wherein the first body and the second body are rotatably connected via a hinge assembly, and the protective cover includes:

[0006] a first shell, the first shell being configured to be connected to the first body, the first shell comprising a first baffle for covering a side frame of the first body;

[0007] a second housing, the second housing being used to cover the hinge assembly, the second housing being rotatably connected to the first housing;

[0008] The first baffle plate has an arc-shaped notch at one end facing the second shell, and the second shell includes a first supporting protrusion matching the arc-shaped notch, and the supporting surface of the first supporting protrusion is an arc-shaped surface matching the shape of the arc-shaped notch;

[0009] When the protective cover is in a folded state, the first supporting protrusion is embedded in the arc-shaped notch, and the supporting surface of the first supporting protrusion is in contact with the inner wall of the arc-shaped notch.

[0010] In a second aspect, a foldable device assembly is provided, comprising a foldable electronic device and the protective cover described in the first aspect, wherein the foldable electronic device comprises a first body and a second body, wherein the first body and the second body are rotatably connected via a hinge assembly, and when the protective cover is installed on the foldable electronic device, the first shell covers the surface of the first body, and the second shell covers the surface of the hinge assembly.

[0011] In the embodiment of the present application, since the first supporting protrusion of the second shell is embedded in the arc-shaped notch of the first shell when the protective cover is in the folded state, and the supporting surface of the first supporting protrusion is in contact with the inner wall of the arc-shaped notch, when the foldable electronic device with the protective cover is in the folded state and the hinge cover of the entire device falls vertically to the ground, the second shell first contacts the ground. At this time, the energy in the second shell can be transferred to the first shell through the supporting surface of the first supporting protrusion, and then dispersed to various positions of the first body through the first shell. In this way, during the falling process, the energy transferred from the second shell to the inner screen hinge assembly will be greatly reduced, which is conducive to reducing the amount of extrusion deformation of the inner screen of the foldable electronic device during the falling process, reducing the risk of black spots and liquid leakage on the inner screen, and improving the protective effect of the protective cover on the foldable electronic device.

[0027] The protective cover and folding device assembly provided in the embodiments of the present application are described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0028] See Figures 1 to 5 The embodiment of the present application provides a protective cover for a foldable electronic device. The foldable electronic device includes a first body 500 and a second body 600. The first body 500 and the second body 600 are rotatably connected via a hinge assembly. The protective cover includes:

[0029] A first housing 100 , the first housing 100 being connected to the first body 500 , and the first housing 100 including a first baffle 110 for covering a side frame of the first body 500 ;

[0030] A second shell 200, the second shell 200 is used to cover the hinge assembly, and the second shell 200 is rotatably connected to the first shell 100;

[0031] The first baffle plate 110 is provided with an arc-shaped notch 111 at one end facing the second shell 200, and the second shell 200 includes a first supporting protrusion 210 matching the arc-shaped notch 111, and the supporting surface 211 of the first supporting protrusion 210 is an arc-shaped surface matching the shape of the arc-shaped notch 111;

[0032] When the protective cover is in the folded state, the first supporting protrusion 210 is embedded in the arc-shaped notch 111 , and the supporting surface 211 of the first supporting protrusion 210 is in contact with the inner wall of the arc-shaped notch 111 .

[0033] The above-mentioned foldable electronic device can be various common foldable electronic devices, such as a foldable screen mobile phone or other similar foldable electronic devices.

[0034] The protective cover can be detachably connected to the foldable electronic device, allowing the user to choose whether to wear the protective cover for the foldable electronic device and to easily replace the protective cover for the foldable electronic device. Alternatively, the protective cover can be fixedly connected to the foldable electronic device, for example, the protective cover is bonded to the outer surface of the foldable electronic device when the foldable electronic device leaves the factory.

[0035] The hinge assembly can be any common hinge connection structure in foldable electronic devices. When the hinge assembly includes a hinge cover, the second housing 200 can cover the outer surface of the hinge cover.

[0036] In some embodiments of the present application, the first body 500 may be a main body of the foldable electronic device, and the second body 600 may be a sub-body of the foldable electronic device.

[0037] The shape of the upper first shell 100 can be adapted to the shape of the first body 500, so that the first shell 100 can wrap the outer surface of the first body 500. Figure 2 The first enclosure plate 110 may be an enclosure plate on the side of the first housing 100 to enclose the side frame of the first fuselage 500. The first supporting protrusion 210 may be a side enclosure of the second housing 200.

[0038] See Figure 1 and Figure 3 The arc-shaped notch 111 may be a notch area formed by removing a corner at one end of the first shell 100 facing the second shell 200, and the supporting surface 211 of the first supporting protrusion 210 may form a track curved surface for changing the follow-up track of the second cover body and the entire machine.

[0039] See Figure 12 (a) In the related art, a protective cover is designed with an escape groove 800 on the second shell 200. This design is passive because the second shell 200 of the protective cover will rest on the surface of the second body 600 during rotation. Long-term opening, closing and folding will cause this area to repeatedly scratch the secondary screen protective film of the entire device, causing scratches on the protective film and significantly shortening its lifespan. The escape groove actually adds additional problems: ① It cannot completely cover the hinge cover, and sand and dust can easily enter the hinge cover through this escape groove 800, scratching the hinge cover. ② The long side of this area cannot effectively support the opposite side middle frame, and its drop resistance is also significantly reduced. Please refer to Figure 12 (b) In the embodiment of the present application, by designing the support surface 211 as a track curved surface, during the rotation process, the track curved surface contacts the surface of the middle frame, which can effectively lift the second shell 200 so that a certain gap is always maintained between it and the secondary screen protective film, and there is no need to dig the avoidance groove 800 on the long side.

[0040] In this embodiment, when the protective cover is in the folded state, the first support protrusion 210 of the second shell 200 is embedded in the arc-shaped notch 111 of the first shell 100, and the support surface 211 of the first support protrusion 210 is in contact with the inner wall of the arc-shaped notch 111. Therefore, when the foldable electronic device with this protective cover is dropped vertically on the ground with the hinge cover facing the ground, the second shell 200 first contacts the ground. At this time, the energy in the second shell 200 can be transferred to the first shell 100 through the support surface 211 of the first support protrusion 210, and then dispersed to various locations of the first body 500 through the first shell 100. In this way, during the drop, the energy transferred from the second shell 200 to the inner screen hinge assembly is significantly reduced, thereby reducing the amount of compression deformation of the inner screen of the foldable electronic device during the drop, reducing the risk of black spots and liquid leakage on the inner screen, and thus improving the protective effect of the protective cover on the foldable electronic device.

[0041] Optionally, the first shell 100 includes two first baffles 110, which are located on two opposite sides of the first shell 100, and a first support protrusion 210 is provided at each end of the second shell 200, and the two first support protrusions 210 in the second shell 200 correspond one-to-one to the two first baffles 110 of the first shell 100.

[0042] See Figure 2 The two first baffles 110 are baffles on both sides of the first shell 100 . Correspondingly, the two first support protrusions 210 are baffles on both sides of the second shell 200 .

[0043] It can be understood that each of the two first enclosure panels 110 is provided with an arc-shaped notch 111. When the protective cover is in a folded state, the first support protrusion 210 is embedded in the arc-shaped notch 111 of the corresponding first enclosure panel 110, and the support surface 211 of the first support protrusion 210 is in contact with the inner wall of the corresponding arc-shaped notch 111.

[0044] In this embodiment, by providing one first supporting protrusion 210 at each end of the second shell 200, and the two first supporting protrusions 210 in the second shell 200 correspond one-to-one to the two first baffles 110 of the first shell 100, when the foldable electronic device with the protective cover is in a folded state and the hinge cover of the entire device falls vertically to the ground, the energy in the second shell 200 can be simultaneously transferred to the first shell 100 through the two first supporting protrusions 210 on both sides thereof, thereby helping to improve the dispersion effect of the energy in the second shell 200 to the first shell 100. And because the two first support protrusions 210 on both sides of the second shell 200 can support the second shell 200 from both sides, when the hinge cover of the entire machine falls vertically to the ground, the energy in the second shell 200 can be simultaneously transmitted to the first shell 100 through the first support protrusions 210 on both sides, thereby further reducing the energy transmitted from the second shell 200 to the inner screen hinge assembly, which is beneficial to reduce the extrusion deformation of the inner screen of the foldable electronic device during the fall, reduce the risk of black spots and liquid leakage on the inner screen, and improve the protection effect of the protective cover on the foldable electronic device.

[0045] Optionally, the support surface 211 includes a first support area 2111 and a second support area 2112;

[0046] When the protective cover is in the folded state, the first supporting area 2111 fits against the inner wall of the arc-shaped notch 111 to support the first shell 100 , and the second supporting area 2112 faces the side frame of the second body 600 to support the second body 600 .

[0047] The protective cover being in the folded state may refer to the state of the protective cover when the foldable electronic device wearing the protective cover is in the folded state.

[0048] See Figure 6 , is a schematic diagram of a protective cover wrapped around a foldable electronic device in the related art, wherein the protective cover is a semi-wrapped structure, that is, it only wraps the main body but not the secondary body. When the whole device is wearing the protective cover, a body step difference close to the thickness of the protective cover will be formed between the main and secondary bodies. Figure 6 In the figure, the height difference between the main body and the secondary body is d. Figure 6When dropped at the angle shown, most of the potential energy of the fall will be transferred through the protective cover to the main body, causing significant twisting and misalignment on both sides. This can severely damage the internal hinges and flexible inner screen. Furthermore, because there is no step difference between the main and secondary bodies when dropped at this angle without a protective cover, the energy of the fall can be absorbed by both sides. However, with a protective cover, only one side absorbs the energy. Wearing a protective cover not only fails to protect the inner screen and hinge, but may actually have a serious negative impact.

[0049] In the embodiment of the present application, when the protective cover is in the folded state, the second support area 2112 can directly contact the side frame of the second body 600 to support the second body 600. Alternatively, when the protective cover is in the folded state, the second support area 2112 can directly contact the area of ​​the hinge cover opposite to the side frame of the second body 600 to support the second body 600 through the hinge cover. Figure 7 When the protective cover is in the folded state, the first supporting protrusion 210 can simultaneously support the first body 500 and the second body 600, thereby eliminating Figure 6 The step difference between the first body 500 and the second body 600 in the folded state is shown. In this way, when falling in the direction parallel to the hinge cover, the falling energy can be equally absorbed by the main and secondary bodies, and no body torque is formed, thereby protecting the inner screen.

[0050] In this embodiment, the support surface 211 includes a first support area 2111 and a second support area 2112, and when the protective cover is in the folded state, the first support area 2111 is in contact with the inner wall of the arc-shaped notch 111 to support the first shell 100, and the second support area 2112 faces the side frame of the second body 600 to support the second body 600. In this way, the step difference between the first body 500 and the second body 600 in the folded state can be eliminated. In this way, during the falling process parallel to the hinge cover direction, the falling energy can be equally absorbed by the main and secondary bodies, so as not to form a body torque, thereby protecting the inner screen.

[0051] Optionally, the second housing 200 further includes a main body portion 220 for covering the hinge assembly, and the first supporting protrusion 210 is a barrier located at an end of the main body portion 220;

[0052] The main body portion 220 includes a second supporting protrusion 240 , which is located between two ends of the main body portion 220 , and a protruding direction of the second supporting protrusion 240 is the same as that of the first supporting protrusion 210 ;

[0053] When the protective cover is in the folded state, the second supporting protrusion 240 faces the side frame of the second body 600 to support the second body 600 .

[0054] Among them, see Figure 1 The above-mentioned main body part 220 refers to: the part of the second shell 200 covering the hinge assembly, that is, the other areas of the second shell 200 except the enclosure, and the first support protrusion 210 is the side enclosure of the main body part 220.

[0055] The protrusion direction of the second support protrusion 240 is the same as the protrusion direction of the first support protrusion 210, which means that the extension direction of the second support protrusion 240 relative to the main body 220 is the same as the extension direction of the first support protrusion 210 relative to the main body 220. Figure 2 In some embodiments of the present application, the protruding directions of the first support protrusion 210 and the second support protrusion 240 are: protruding from the inner wall of the main body part 220 toward the inner side of the protective cover in a direction perpendicular to the main body part 220.

[0056] The number of the second supporting protrusion 240 can be 1 or more than 1, see Figure 2 In some embodiments of the present application, the number of the second support protrusions 240 is three, and the three second support protrusions 240 are arranged between the two ends of the main body part 220 at intervals along the length direction of the main body part 220.

[0057] The main material of the main body portion 220 may be plastic, wherein the second supporting protrusion 240 and the first supporting protrusion 210 may both be protrusions made of plastic extending from the main body portion 220 .

[0058] In the embodiment of the present application, when the protective cover is in the folded state, the second supporting protrusion 240 can directly contact the side frame of the second body 600 to support the second body 600. Alternatively, when the protective cover is in the folded state, the second supporting protrusion 240 can directly contact the area of ​​the hinge cover opposite the side frame of the second body 600 to support the second body 600 via the hinge cover.

[0059] In this embodiment, since the first support protrusions 210 only support the two ends of the second housing 200, the area between the two ends of the second housing 200 is susceptible to inward deformation when subjected to impact, thereby compressing the inner screen of the foldable electronic device. In other words, the area between the two ends of the second housing 200 is a weak area of ​​the second housing 200. Based on this, in this embodiment of the present application, the main body 220 includes a second support protrusion 240, which is located between the two ends of the main body 220. When the protective cover is in the folded state, the second support protrusion 240 faces the side frame of the second body 600 to support the second body 600. In this way, during a drop, the second support protrusion 240 can first support the side wall of the middle frame of the second body 600, further reducing the pressure on the hinge cover during the drop, thereby effectively reducing the extent of the hinge cover's inward collapse.

[0060] Optionally, the protective cover also includes a first flexible protective layer 300 and a second flexible protective layer 400, wherein the first flexible protective layer 300 covers the inner surface of the first shell 100 and the inner surface of the second shell 200, and the second flexible protective layer 400 covers the outer surface of the first shell 100 and the outer surface of the second shell 200.

[0061] The first flexible protective layer 300 and the second flexible protective layer 400 may be protective layers made of various flexible materials, for example, they may be leather layers made of leather material, or they may be flexible protective layers made of other materials having similar properties to leather material.

[0062] See Figure 1 In some embodiments of the present application, the first flexible protective layer 300 is the inner layer of the protective cover, and the second protective layer is the outer layer of the protective cover. The first housing 100 and the second housing 200 are connected by the inner and outer layers of the leather. The leather is a flexible material. When the first body 500 and the second body 600 rotate relative to each other, the flexible connection structure formed by the inner and outer layers of the leather can self-deform, effectively adapting to different angles of the entire device and allowing the second housing 200 to adjust its orientation adaptively.

[0063] exist Figure 1 In the embodiment shown, since the first body 500 and the second body 600 are connected by the inner and outer layers of the plain leather structure, one side of the second housing 200 cannot be effectively supported on the middle frame. Figure 11In some embodiments of the present application, the first flexible protective layer 300 and the second flexible protective layer 400 can be replaced with several flexible connecting strips 700. The flexible connecting strips 700 can connect the first shell 100 and the second shell 200 by bonding or riveting. Because the flexible connecting strips 700 do not need to be very wide, the coverage area of ​​the plastic in the second shell 200 can be adjusted along the length of the entire device, thereby providing effective support for the middle frame on both sides and further improving the protective effect.

[0064] It is understandable that the first supporting protrusion 210 and the second supporting protrusion 240 may respectively pass through the first flexible protective layer 300 to support the first body 500 and the second body 600 of the foldable electronic device.

[0065] In this embodiment, by making the protective cover also include a first flexible protective layer 300 and a second flexible protective layer 400, the first flexible protective layer 300 can simultaneously cover the inner surface of the first shell 100 and the inner surface of the second shell 200, and the second flexible protective layer 400 simultaneously covers the outer surface of the first shell 100 and the outer surface of the second shell 200. In this way, when the first body 500 and the second body 600 rotate relative to each other, the flexible connection structure formed by the first flexible protective layer 300 and the second flexible protective layer 400 can self-deform, so that it can effectively adapt to the different angles of the whole machine, so that the second shell 200 can adaptively adjust its orientation.

[0066] Optionally, a buffer groove 250 is provided on the inner surface of the second shell 200 , and the first flexible protective layer 300 covers the notch of the buffer groove 250 .

[0067] The depth of the buffer groove 250 may be between 0.1 mm and 0.2 mm. For example, in some embodiments of the present application, the depth of the buffer groove 250 is 0.15 mm.

[0068] See Figure 5 In some embodiments of the present application, the buffer groove 250 is arranged near the end of the main body part 220.

[0069] In this embodiment, a buffer groove 250 is provided on the inner surface of the second shell 200, and the first flexible protective layer 300 covers the notch of the buffer groove 250. In this way, the buffer groove 250 can form an air gap between the second shell 200 and the first flexible protective layer 300, so as to effectively increase the deformation of the second shell 200 at the buffer groove 250. Since the second shell 200 is deformed at the buffer groove 250 during the falling process, the second shell 200 itself can absorb part of the energy, thereby further reducing the squeezing force on the inner screen.

[0070] Alternatively, see Figure 8 A reinforcing piece 230 is embedded in the second shell 200 , and the reinforcing piece 230 is arranged along the length direction of the second shell 200 .

[0071] The reinforcing member 230 can be a reinforcing structure made of various hard materials. The number and shape of the reinforcing members 230 can be customized as needed. For example, the reinforcing member 230 can be in the form of a plate, a rod, or a grid, and the number of reinforcing members 230 can be one or more.

[0072] It is understandable that the second housing 200 may be made of plastic, and the reinforcing piece 230 is embedded in the plastic of the second housing 200. The length direction of the second housing 200 is the same as the length direction of the reinforcing piece 230.

[0073] In this embodiment, by embedding a reinforcing piece 230 in the second shell 200 and setting the reinforcing piece 230 along the length direction of the second shell 200, the reinforcing piece 230 can enhance the structural strength of the second shell 200, making the energy absorption capacity of the second shell 200 stronger.

[0074] Alternatively, see Figure 9 The reinforcing piece 230 is a strip-shaped steel sheet, and a strip-shaped groove 231 is provided on the reinforcing piece 230. The strip-shaped groove 231 is located in the middle area of ​​the reinforcing piece 230, and the length direction of the strip-shaped groove 231 is the same as the length direction of the reinforcing piece 230. The notch of the strip-shaped groove 231 faces the inner surface of the second shell 200; the two sides of the reinforcing piece 230 in the width direction are respectively bent toward the outer surface of the second shell 200.

[0075] The reinforcing member 230 may be made of stainless steel, or other steel materials having properties similar to those of stainless steel.

[0076] The number of the strip grooves 231 can be 1 or more than 1. When the number of the strip grooves 231 is more than 1, all the strip grooves 231 can be sequentially spaced along the length direction of the reinforcing member 230. For example, see Figure 10 In some embodiments of the present application, the number of the strip-shaped grooves 231 is 5.

[0077] In this embodiment, a strip groove 231 is provided on the reinforcing piece 230, and the strip groove 231 is located in the middle area of ​​the reinforcing piece 230, and the length direction of the strip groove 231 is the same as the length direction of the reinforcing piece 230, and the notch of the strip groove 231 is toward the inner surface side of the second shell 200; at the same time, the two sides of the reinforcing piece 230 in the width direction are bent toward the outer surface side of the second shell 200 respectively. In this way, the reinforcing piece 230 can have better strength in a limited thickness space.

[0078] Optionally, at least two positioning holes 232 are defined at the bottom of the strip-shaped groove 231 , and the second shell 200 includes at least two positioning posts corresponding to the at least two positioning holes 232 , and the positioning posts are inserted into the corresponding positioning holes 232 .

[0079] During the molding process of the second shell 200, to ensure greater strength for the reinforcing piece 230 within the limited thickness, the two sides of the reinforcing piece 230 are first bent so that a small portion of the reinforcing piece 230 is flush with the plastic of the second shell 200 and exposed, secured by the mold, while the majority of the reinforcing piece 230 is embedded within the plastic of the second shell 200. Next, a concave platform is stamped into the center of the reinforcing piece 230. This concave platform serves as the aforementioned strip-shaped groove 231, and two positioning holes 232 are stamped into this concave platform. The plastic in the second shell 200 can pass through these positioning holes 232, and the plastic inserted into these positioning holes 232 forms the aforementioned positioning posts. This ensures that the reinforcing piece 230 is positioned within the second shell 200. This arrangement enhances the longitudinal strength of reinforcement 230, making it less susceptible to deformation under external pressure. It also prevents the majority of the steel sheet from being exposed within the plastic, facilitating plastic molding and preventing issues with the inner and outer skins and large areas of stainless steel sheet from being securely bonded. If the impact energy is excessive or the hinge cover falls vertically onto an uneven surface, and the protective cover cannot withstand the impact and deforms or cracks, the protective cover can be supported by the middle frame on the opposite side of the device, providing secondary support.

[0080] In this embodiment, at least two positioning holes 232 are provided at the bottom of the strip-shaped groove 231, and the second shell 200 includes at least two positioning columns corresponding to the at least two positioning holes 232, and the positioning columns are passed through the corresponding positioning holes 232. In this way, the position of the reinforcement part 230 in the second shell 200 can be achieved.

[0081] It should be noted that the protective cover provided in the embodiment of the present application has at least the following beneficial effects: compared to conventional protective covers, it can effectively improve the problem of twisting, dislocation and failure of the inner screen of the folding screen when the conventional protective cover falls in the direction parallel to the hinge cover. At the same time, it can provide better support when falling perpendicular to the hinge cover, and provide greater protection for the inner screen. Targeted adjustment of the support structure to the weak area of ​​the hinge can effectively improve the protection capability of the weak area, so that there are no obvious weak points in the entire hinge area, and the inner screen of the folding screen is fully protected.

[0082] An embodiment of the present application also provides a folding device assembly, including a folding electronic device and the protective cover described in the above embodiment, the folding electronic device includes a first body 500 and a second body 600, the first body 500 and the second body 600 are rotatably connected through a hinge assembly, when the protective cover is installed on the folding electronic device, the first shell covers the surface of the first body, and the second shell covers the surface of the hinge assembly.

[0083] The above-mentioned foldable electronic device can be various common foldable electronic devices, such as a foldable screen mobile phone or other similar foldable electronic devices.

[0084] In this embodiment, since the folding device assembly includes the protective cover in the above embodiment, the folding device assembly can implement each process of the protective cover in the above embodiment and has the same beneficial effects. To avoid repetition, it will not be described here.

[0085] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
