[0002] Some existing folding devices, such as folding mobile phones, provide a protective shell on the outer layer of the folding device in order to protect the folding device in the unfolded state and the folded state. When the folding device falls, the impact resistance encountered by the folding device during the fall is cushioned to ensure that the screen and internal parts of the folding device are not excessively damaged.

[0003] An existing method uses a frame to protect the sides, and soft glue is used to connect the main frame and the sub-frame in the hinge area. Although this method provides a certain degree of protection for the sides of the device, this method of protection has no protection structure for the hinge part of the device. When the entire device falls, the hinge is still easily damaged, and the reliability protection is poor, which affects the user experience. Summary of the invention

[0004] In view of this, the present application provides a protective case and an electronic device, which are used to solve the problem that the protective case of the current folding device cannot protect the hinge area of ​​the device, resulting in poor protection.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0047] In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the technical problems to be solved by the embodiments of the present application are first described.

[0048] refer to Figure 1 , Figure 1 A schematic diagram of the structure of a foldable mobile phone with a protective case in some embodiments is shown. Figure 1 (a) is a schematic diagram of the structure of a foldable mobile phone; Figure 1 (b) is a schematic diagram of the structure of the foldable mobile phone from another angle. Figure 1 As shown, the protective shell 20 may include a main frame 21 and a sub-frame 22. The main frame 21 is arranged on the side corresponding to the main screen 11 of the folding mobile phone 10. The sub-frame 22 is arranged on the side corresponding to the sub-screen of the mobile phone 10. The hinge area 13 uses soft glue to connect the main frame 21 and the sub-frame 22. When the mobile phone 10 falls, if the side of the mobile phone 10 touches the ground, the protective shell 20 can play a better protective role. This protective shell does not protect the hinge area 13 of the folding mobile phone 10. If the mobile phone falls, the hinge area 13 is not protected, which will cause a high risk of damage to the mobile phone, and the reliability of the safety protection of the whole machine is poor.

[0049] In order to solve the problem of poor reliability of mobile phones, in some embodiments, the hinge area is protected.

[0050] refer to Figure 2 , Figure 2 The schematic diagrams of the structure of the foldable mobile phone with a protective case in other embodiments are shown. Figure 2 (a) is a schematic diagram of the structure of a foldable mobile phone; Figure 2 (b) is a schematic diagram of the structure of the foldable mobile phone from another angle. Figure 2As shown, the folding mobile phone 10 is provided with a protective shell 30, and the protective shell 30 adopts a leather case structure, and the leather case structure includes a first shell 31 and a second shell 32 connected to each other. One side of the first shell 31 is rotatably connected to one side of the main screen, and the first shell covers the main screen of the folding mobile phone and blocks a large area of ​​the main screen. The second shell bypasses the rotating shaft of the folding mobile phone and covers the secondary screen. Since the connection between the first shell 31 and the second shell 32 covers the rotating shaft area 13, the folding mobile phone 10 can be more comprehensively protected. However, this protective shell is relatively cumbersome when used. For example, when the user switches from the folding state of the folding mobile phone 10 to the unfolded state, it is necessary to first open the first shell 31 and the second shell 32 to the side of the main screen, expose the secondary screen 12, and then press the button to unfold it to the full screen. In the folded state, the protective shell also needs to be flipped over. For example, when the main screen 11 is used in the folded state, the user needs to open both the first shell 31 and the second shell 32. If the secondary screen 12 is used in the folded state, the user needs to open the second shell 32. The protective shell 30 of this structure is complicated to operate, which affects the user experience.

[0051] In other embodiments, reference Figure 3 , Figure 3 The schematic diagrams of the structures of the protective devices for wearing foldable mobile phones in some other embodiments are shown. Figure 3 (a) is a schematic diagram of the structure of a foldable mobile phone; Figure 3 (b) is a schematic diagram of the structure of the foldable mobile phone from another angle. Figure 3 As shown, a protective device 40 is provided on the foldable mobile phone 10, and the protective device 40 adopts a half-wrapped and buckled structure. In the folded state, the leather case 41 fully covers the secondary screen, and the user does not need to manually flip the leather case 41 when using it in the folded state. However, the hinge area 13 is buckled by a hard rubber buckle 42. When unfolding the foldable mobile phone 10, the buckle 42 of the hinge area 13 needs to be disassembled and folded, and then the button is pressed to unfold the foldable mobile phone 10. A bracket 43 is provided on the outside of the leather case 41 for support, but this operation is relatively cumbersome.

[0052] In order to solve the shortcomings of the protective case of the foldable mobile phone in the above embodiment when in use, the embodiment of the present application provides a protective case, which is provided with a fixed part and a folding mechanism that rotates relative to the fixed part, and the folding mechanism is provided as a simple frame structure, which can not only protect the foldable mobile phone and improve the reliability of the whole machine, but also has a simple structure and is easy to operate when in use, thereby improving the user experience. The structure and use of the protective case of the embodiment of the present application are described in detail below in conjunction with the accompanying drawings.

[0053] The protective case of the embodiment of the present application can be applied to electronic devices, wherein the electronic device can be, but is not limited to, a folding screen mobile phone, a folding computer, and other electronic devices. In addition, in some embodiments, it can also be applied to electronic devices such as a straight-screen mobile phone or a tablet computer. In the following embodiments, the electronic device is a folding mobile phone and an external folding screen mobile phone as an example for explanation.

[0054] See also Figure 4 and Figure 5 , Figure 4 A schematic diagram of the structure in which a protective shell according to an embodiment of the present application is installed on a foldable mobile phone is shown. Figure 5 A schematic structural diagram of a protective shell according to an embodiment of the present application is shown.

[0055] Among them, Figure 4 As shown, in the embodiment of the present application, the foldable mobile phone is described as a rectangular structure of the foldable mobile phone. For example, two opposite sides are parallel to each other. Therefore, the first direction is parallel to the side of the foldable mobile phone (such as Figure 4 The first direction is parallel to the bottom edge of the rotating shaft and parallel to the extension direction of the rotating shaft. In some embodiments, the first direction may also intersect with the extension direction of the rotating shaft, and may be set according to actual product design requirements. The second direction is different from the first direction, and the second direction may be any direction around the first direction. The first direction may be perpendicular to the second direction, or may form a non-perpendicular relationship.

[0056] It should be noted that the rotation axis or rotation axis area mentioned in the embodiments of the present application may include the rotation axis and its corresponding bending area of ​​the folding screen, and the rotation axis or rotation axis area will be used for explanation in the following embodiments.

[0057] like Figure 4 and Figure 5 As shown, the protective shell 200 includes a fixing portion 210 and a folding mechanism 220. The fixing portion 210 extends along a first direction. When in use, the fixing portion 210 can be sleeved on the side of the folding device (such as Figure 4 The bottom edge of the folding mechanism 220, i.e., the side away from the rotating shaft), wherein the side edge can be the edge of an electronic device, or a frame with a locking mechanism for a camera, a button, and a lock screen. The fixing portion can protect both the side edge and the components disposed on the side edge. The fixing portion can form a stable rotation support for the folding mechanism. The folding mechanism 220 may include two connecting members 221 and a rotating shaft frame 222. The left end of the two connecting members 221 (such as Figure 4The left end shown in the figure, corresponding to the first end) is rotatably connected to the two ends of the fixing part 210, and the connecting member 221 extends along the second direction, so that the folding mechanism 220 and the fixing part 210 can rotate relative to each other, which is convenient for the folding mechanism 220 to be engaged or separated from the folding mobile phone 100. The two ends of the rotating shaft frame 222 are respectively connected to the right end of the two connecting members (such as Figure 4 The right end shown in the figure, corresponding to the second end) is connected so that the fixing part 210, the connecting member 221 and the hinge frame 222 form a square frame, which is arranged around the four sides of the folding mobile phone 100. During the falling process of the whole device, the protective shell 200 reduces the vibration and buffers the resistance on the four sides of the folding device 100, realizes the protection of the three sides of the folding mobile phone 100 and the side with the hinge (the folding screen corresponding to the hinge position), and improves the reliability of protection.

[0058] In addition, the inner side of the rotating shaft frame 222 (such as Figure 4 As shown, a receiving groove 2221 (first receiving groove) is provided on one side close to the fixing portion 210. When the folding mobile phone 100 is in a folded state, the receiving groove 2221 can accommodate the folding screen at a position corresponding to the rotating shaft 130 of the folding mobile phone 100 (the folding screen 140 at the bend), and when the folding mechanism 220 is buckled at a position corresponding to the rotating shaft 130 of the folding mobile phone, a gap is formed between the receiving groove 2221 and the folding screen 140 at the bend, that is, the receiving groove 2221 provides an avoidance space for the folding screen 140 at the bend to prevent the folding screen 140 at the bend from being worn.

[0059] like Figure 4 As shown, the length of the receiving groove 2221 matches the length of the rotating shaft 130 (or the length of the side of the mobile phone on the rotating shaft side), that is, the receiving groove 2221 is just engaged with the rotating shaft. For example, when the folding mechanism 220 is engaged with the corresponding position of the rotating shaft 130 of the folding mobile phone 100, the side walls at both ends of the receiving groove can be engaged with the two side walls of the rotating shaft 130. The inner wall of the receiving groove 2221 does not contact the folding screen 140 at the bend. This structure not only facilitates the engagement of the two sides of the receiving groove 2221 with the two ends of the side at the rotating shaft 130 of the mobile phone, but also facilitates the separation of the rotating shaft frame 222 from the rotating shaft 130, and the operation is convenient and easy.

[0060] It should be noted that the engagement between the receiving groove 2221 and the rotating shaft 130 can be achieved by the toughness or deformation of the folding mechanism 220 itself, such as using plastic materials, or other materials. In order to achieve a better engagement effect, two pairs of grooves 2222 matching the rotating shaft 130 can be set on both sides of the receiving groove 2221, so that the folding mobile phone 100 and the rotating shaft frame 222 can be better engaged.

[0061] In some embodiments, the rotating shaft frame 222 may be formed by extending from the end of the connecting member 221, so that the folding mechanism 220 forms a shape similar to a sickle or a shape of the number "7" (eg, Figure 5 The folding mechanism shown is like a sickle), which is more conducive to fully covering the area corresponding to the rotating shaft 130 and playing a better protective role. In addition, this structure is easy to operate when engaging or disengaging with the folding mobile phone 100.

[0062] The protective case 200 is described below with reference to the structural schematic diagrams of the protective case 200 and the foldable mobile phone 100 in the engaged state and the separated state.

[0063] refer to Figure 6 , Figure 6 FIG. 2 shows a side view of the protective case 200 of the embodiment of the present application and the foldable mobile phone 100 in a buckled state. Figure 6 As shown, the foldable phone 100 is in a folded state, and the protective shell 200 is buckled on the periphery of the foldable phone 100 in the folded state and is in contact with the side edge ( Figure 6 The hinge frame 222 is overlapped with the side blocked by the connecting member 221 in the opposite direction. The hinge frame 222 is buckled at the corresponding position of the hinge 130 of the foldable mobile phone 100. Thus, the folding screen 140 and the hinge 130 at the three sides and the bend of the foldable mobile phone 100 are protected when the foldable mobile phone 100 is in the folded state.

[0064] Further, refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the protective case of the embodiment of the present application when it is buckled with the foldable mobile phone from another angle. Figure 7 (a) is the same as Figure 6 The corresponding bottom view; Figure 7 (b) is the same as Figure 6 The corresponding top view.

[0065] like Figure 7 As shown in (a) and (b), when the protective case 200 and the foldable mobile phone 100 are in a buckled state, the main screen 110 and the sub-screen 120 are not blocked through the hollow frame structure formed by the connector 221 and the hinge frame 222. The user can directly use the main screen 110 or the sub-screen 120 when the protective case 200 is in the buckled state, and there is no need to disassemble and flip the protective case 200, which is convenient to operate and improves the user experience. In addition, the surroundings and the hinge of the mobile phone are effectively protected, thereby improving the reliability of the entire machine.

[0066] refer to Figure 8 , Figure 8 FIG. 1 shows a schematic diagram of the structure of the foldable mobile phone 100 according to an embodiment of the present application when it is in an unfolded state. Figure 8As shown, if the user wants to open the folding screen of the folding mobile phone 100, the folding mechanism 220 can be manually opened to rotate the folding mechanism 220 around the fixing part 210 and separate from the main screen 110 and the sub-screen 120 of the folding mobile phone 100. At this time, the user can operate the folding screen to unfold. In addition, the user can also directly open the folding screen, and the folding mechanism 220 is automatically pushed open when the folding screen (sub-screen 120) rotates, realizing one-key unfolding, and the whole process is simple and convenient to operate.

[0067] The following is a detailed description of the various components of the protective case 200 according to the embodiment of the present application in conjunction with the accompanying drawings.

[0068] refer to Fig. 9 , Fig. 9 FIG. 2 is a schematic diagram showing the structure of the fixing portion 210 of an embodiment of the present application. Fig. 9 As shown, the fixing part 210 may include a fixing part body 211 and two shielding plates 212. The fixing part body 211 includes an accommodation space 213 (corresponding to the second accommodation groove) extending along the first direction and having a side opening. The accommodation space 213 is used to cover the side of the folding device (such as Figure 4 As shown, the fixing part 210 is sleeved on the side of the foldable mobile phone 100). The shielding plates 212 are respectively arranged at both ends of the fixing part body 211 and connected to the fixing part body 211 to cover both ends of the accommodating space 213 to better protect the side of the foldable mobile phone. After the fixing part body 211 covers the side of the foldable mobile phone, the folding mechanism (such as Figure 8 The rotation of the folding mechanism 220) plays a role in stabilizing support.

[0069] In some embodiments, the shielding plate 212 and the fixing portion body 211 may be integrally formed to improve the stability of the overall structural connection.

[0070] like Fig. 9 As shown, the fixing body 211 may be provided with a plurality of hollow holes 214 for passing through the components arranged on the side, and these hollow holes 214 can pass through various components, such as a camera, a power key, a volume key, a folding screen unlocking key, etc. The shape of the hollow hole 214 can be set to different shapes as needed, and the embodiment of the present application is not limited to this.

[0071] In some embodiments, the protective shell 200 may be made entirely or partially of plastic material, which is a low-cost material with good toughness and is more conducive to protecting the foldable mobile phone.

[0072] like Fig. 9As shown, the protective shell may further include two symmetrically arranged rotating mechanisms 230. The two rotating mechanisms 230 are respectively arranged at both ends of the fixing portion 210, and one end of the rotating mechanism 230 is connected to the fixing portion 210, and the other end is connected to the connecting member (see Figure 5 The connection member 221 in the embodiment can be rotatably connected. The fixing part 210 and the folding mechanism (see FIG. 2 ) are connected by the rotating mechanism 230. Figure 5 The folding mechanism 220 is rotatably connected to the fixing portion 210, so that the folding mechanism can rotate relative to the fixing portion 210, for example, the folding mechanism can rotate 360 ​​degrees around the axis of the rotating mechanism 230, thereby realizing the free rotation of the folding mobile phone and the folding mechanism in the engaged and separated states.

[0073] In some embodiments, the rotating mechanism 230 may be in the form of a hot-melt plastic column or a pin.

[0074] Continue to refer Figure 5 and Fig. 9 ,like Fig. 9 As shown, the rotating mechanism 230 may include a pin shaft 231, one end of which is fixedly connected to the shielding plate 212, and the other end of which extends to a side away from the shielding plate 212. Figure 5 As shown, a through hole 2211 is provided on the first end of the connecting member 221, and a pin 231 passes through the through hole 2211, so that the rotating mechanism 230 is rotatably connected to the connecting member 221. The rotation of the folding mechanism 220 relative to the fixing part 210 is realized by the connecting structure of the pin 231 and the through hole 2211, which has a simple structure and is easy to implement.

[0075] In some embodiments, the rotating mechanism 230 may also be composed of a bearing structure, a gear mechanism, etc. to achieve a rotatable connection with the connecting member 221, and the present application does not make a sole limitation to this.

[0076] The structure and function of the rotating mechanism 230 and the connecting member 221 are further described in detail below in conjunction with the accompanying drawings.

[0077] like Fig. 9 As shown, the rotating mechanism 230 also includes a mounting portion 232. The mounting portion 232 is connected to the shielding plate 212, and a limiting groove 2321 is formed on the outer wall of the mounting portion 232. A pin 231 is provided inside the limiting groove 2321. Figure 5 As shown, when the first end of the connecting member 221 is sleeved on the pin 231, the end or a part of the connecting member 221 can be placed in the limiting groove 2321. The setting of the limiting groove 2321 can limit the rotation of the end of the connecting member 221, making the rotation of the connecting member more stable.

[0078] In some embodiments, the mounting portion 232 may also be a part of the shielding plate 212, or a part of the fixing portion 210, that is, the fixing portion body 211, the shielding plate 212 and the mounting portion 232 of the fixing portion 210 are a structural body or integrally formed. This application does not limit this.

[0079] In some embodiments, a notch may be formed on one side of the limiting groove 2321, and a connecting member (such as Figure 5 The connecting member 221 shown in the figure passes through the notch, and the notch limits the rotation angle of the connecting member relative to the fixing portion 210 to prevent the folding mechanism from rotating too much.

[0080] refer to Fig.10 and Fig.11 , Fig.10 A schematic diagram of the structure of the mounting portion 232 of an embodiment of the present application is shown; Fig.11 A partial structural schematic diagram of the connecting member 221 according to an embodiment of the present application is shown.

[0081] like Fig.10 As shown, a first step surface a1 is formed on the end surface of the bottom of the limiting groove 2321. Fig.11 As shown, a second step surface b1 is formed on the connecting member 221. During actual installation, the first step surface a1 and the second step surface b1 are arranged correspondingly. Fig.10 and Fig.11 As shown, when the connecting member 221 rotates clockwise around the pin shaft 231 (corresponding to the first rotation direction), the first step surface a1 and the second step surface b1 do not interfere with each other. When the connecting member 221 rotates counterclockwise around the pin shaft 231 (corresponding to the second rotation direction) to a certain angle, the second step surface b1 and the first step surface a1 abut against each other, so that the connecting member 221 cannot continue to rotate counterclockwise, forming a stop structure, thereby realizing the supporting function of the folding mechanism, and the folding mechanism can be used as a bracket to support the entire machine, which is convenient for users to use.

[0082] Combination Fig.10 and Fig.11 , and refer to Fig.12 , Fig.12 FIG. 2 shows a schematic cross-sectional structure diagram of the first step surface a1 and the second step surface b1 of the embodiment of the present application being engaged with each other. Fig.10 , Fig.11 and Fig.12 As shown, the first step surface a1 in the limiting groove 2321 and the second step surface b1 on the connecting member 221 abut against each other when rotating counterclockwise, thereby effectively preventing the connecting member 221 from rotating relative to the pin 231. At this time, the folding mechanism functions as a bracket, which can stably support the foldable mobile phone and facilitate user use.

[0083] Continue to refer Fig.10 and Fig.11 ,like Fig.10 and Fig.11 As shown, a bevel area a2 and a plurality of fan-shaped areas a3 may be provided in the limit groove 2321. Among them, the plurality of fan-shaped areas a3 are arranged into a continuous step structure in a clockwise direction (corresponding to the first rotation direction) with the pin shaft 231 as the center. The bevel area a2 connects the fan-shaped area at the head and the fan-shaped area at the tail of the step structure. The free rotation of the folding mechanism around the axis is achieved through the bevel area a2. A first step surface a1 is formed between every two fan-shaped areas a3 to form a plurality of first step surfaces a1. By adopting the setting mode of the plurality of first step surfaces a1, when the connecting member 221 rotates, the first step surfaces a1 at different positions can be engaged with the second step surfaces b1 to achieve the support of the folding mechanism for the display screen at different angles, thereby meeting the customer's requirements for different tilt angles of the display screen.

[0084] In the embodiments of the present application, Fig.10 As shown, the limiting groove 2321 may be provided with three consecutively arranged sector areas a3, the total center angle of the three sector areas a3 is 90 degrees, and the center angle of the inclined surface area a2 may be 270 degrees. Among them, the setting mode of setting the center angle of 90 degrees can realize the adjustment of the rotation angle of the folding mechanism from 0 degrees to 90 degrees. And 0 degrees indicates that the folding mechanism overlaps with the side of the folding mobile phone (such as Figure 6 The two are in a buckled state. The tilt angle of the display screen can be adjusted in three levels within the range of greater than 0 to 90 degrees. For example, if the central angle of each sector area is 30 degrees, the corresponding support angle between the folding mechanism and the display screen can be 30 degrees, 60 degrees and 90 degrees. Users can adjust it as needed.

[0085] In some embodiments, the angle of each sector area may also be different angles such as 10 degrees, 20 degrees, 40 degrees, etc. In actual production, it can be set according to the user's requirements for the tilt angle of the display screen, and the embodiments of the present application are not limited to this.

[0086] In some embodiments, Fig.11 As shown, the second step surface b1 may also be provided in plurality, and the plurality of second step surfaces b1 are combined with the plurality of first step surfaces a1 within a set angle, thereby improving the support stability of the folding mechanism.

[0087] The corresponding relationship between the folding mechanism and the angle adjustment of the foldable mobile phone is described below in conjunction with the accompanying drawings.

[0088] refer to Fig.13 and Fig.14 , Fig.13 A diagram showing the correspondence between the rotation angle of the folding bracket and the tilt angle of the folding screen according to an embodiment of the present application is shown. Fig.14 A diagram showing the correspondence between the rotation angle of the folding bracket and another tilt angle of the folding screen according to an embodiment of the present application is shown.

[0089] like Fig.13 As shown in (a) in the figure, when the connector (reference Fig.13 The second step surface of the connecting member 221 in (b) and the second first step surface a1 ( Fig.13 When (a) the second one in the clockwise direction is engaged, Fig.13 As shown in (b), the angle between the corresponding folding mechanism 220 and the unfolded folding mobile phone 100 is 90 degrees. The folding screen of the folding mobile phone 100 maintains a slightly tilted posture, which is convenient for users to view the display screen.

[0090] like Fig.14 As shown in (a) in the figure, when the connector (reference Fig.13 The second step surface of the connecting member 221 in (b) and the third first step surface a1 ( Fig.12 When the third one (counterclockwise) is engaged, Fig.14 As shown in (b), the corresponding angle between the folding mechanism 220 and the folding mobile phone 100 is 60 degrees. The folding screen maintains a larger tilt angle, allowing users to adjust the folding screen to different viewing angles.

[0091] In some embodiments, Fig.14 As shown, when the connecting member 221 is engaged with the fixing portion 210, if the connecting member 221 is to be rotated, the appropriate angle can be selected by rotating the connecting member 221 counterclockwise. The distance between the connecting member 221 and the bottom end face of the limiting groove 2321 can also be adjusted so that the first step surface a1 and the second step surface are no longer engaged. For example, the pin 231 is a telescopic structure, or can be screwed in or out relative to the bottom end face of the limiting groove 2321, so that the connecting member 221 has a certain space to move outward and avoid the stop of the first step surface a1. After adjustment, the connecting member 221 is brought close to the bottom end face of the limiting groove 2321 to achieve the engaged state, thereby adjusting the angle. The embodiments of the present application are not limited to this.
