Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic device accessories, and in particular to a protective case and an electronic device. Background Art

[0002] With the development of the market, foldable electronic devices are becoming more and more popular. Foldable electronic devices are deeply loved by consumers because of their larger display area and good portability. The protection demand for foldable electronic devices has also increased accordingly. The foldable protective case can protect the foldable electronic device from scratching, falling, and shock, etc., and can also decorate its appearance. In addition, when the foldable electronic device is in a folded state, it can fully protect the hinge part and prevent dust from entering the body of the foldable electronic device from the hinge part.

[0003] The foldable protective case generally includes: a bottom case and a hinge cover. The bottom case is used to cover the main body parts on both sides of the hinge mechanism of the foldable electronic device, and the hinge cover is used to cover the hinge mechanism of the foldable electronic device. The bottom case and the hinge cover are generally connected by a polyurethane (PU) leather. The PU leather has two layers, which are respectively pasted on the inner and outer sides of the bottom case and the hinge cover.

[0004] However, assembling the bottom case and the hinge cover in this way has a complex process and a high cost. Summary of the Invention

[0005] The embodiments of the present application provide a protective case and an electronic device, which can reduce the assembly process of the protective case, lower the production cost of the protective case, improve the feel of the protective case and the user experience of consumers, and also improve the shaping consistency of the protective case.

[0006] On the one hand, the embodiments of the present application provide a protective case, including: a first shell and a second shell. The first shell is used to cover the outside of the hinge mechanism of the foldable electronic device, and the second shell is used to cover the outside of the main body part of the foldable electronic device. The first shell and the second shell are formed with a soft glue layer by an in-mold injection process to connect the first shell and the second shell, and the first shell and the second shell are relatively rotatably arranged.

[0007] The protective case provided by the embodiment of the present application forms a soft glue layer through in-mold injection molding process to connect the first shell and the second shell. Without affecting the relative rotation of the first shell and the second shell, the thickness and composition of the soft glue layer can be adjusted to regulate the softness and hardness of the connection between the first shell and the second shell, which is beneficial to improving the hand feeling and the user experience of consumers. Moreover, the soft glue layer formed by in-mold injection molding process can be well connected with the first shell and the second shell, which is beneficial to improving the shaping consistency. In addition, the assembly process of the first shell and the second shell can be reduced, and the assembly cost can be reduced, which is beneficial to the mass production of the protective case.

[0008] In a possible implementation manner, the soft glue layer includes: a connection layer, and at least part of the connection layer is formed on the surfaces of the first shell and the second shell facing away from the foldable electronic device.

[0009] Compared with the way that the soft glue layer is formed between the first shell and the second shell, the connection stability between the first shell and the second shell can be improved. Compared with the way that the soft glue layer is formed on the surfaces of the first shell and the second shell facing the foldable electronic device, the aesthetics of the protective case can be improved. Compared with the way that the soft glue layer is formed on the surfaces of the first shell and the second shell facing the foldable electronic device and on the surfaces of the first shell and the second shell facing away from the foldable electronic device at the same time, the single-layer soft glue layer can improve the user experience of consumers. Compared with the way that the soft glue layer is formed on the surface of the first shell facing away from the foldable electronic device and the surface of the second shell facing the foldable electronic device, and the soft glue layer is formed on the surface of the first shell facing the foldable electronic device and the surface of the second shell facing away from the foldable electronic device, the risk of tearing of the soft glue layer during the relative rotation of the first shell and the second shell can be reduced.

[0010] In a possible implementation manner, the soft glue layer further includes: a first extension layer integrally provided with the connection layer, the first extension layer is disposed on the side of the second shell close to the first shell, and the first extension layer extends along the side wall of the second shell to the surface of the second shell facing the foldable electronic device.

[0011] In this way, the risk of tearing and debonding of the soft glue layer can be reduced, and the service life of the protective case can be improved.

[0012] In a possible implementation manner, the soft glue layer further includes: a second extension layer integrally provided with the connection layer, the second extension layer is disposed on the side of the first shell close to the second shell, and the second extension layer extends along the side wall of the first shell to the surface of the first shell facing the foldable electronic device.

[0013] In this way, the risk of tearing and debonding of the soft glue layer can be reduced, and the service life of the protective case can be improved.

[0014] In a possible implementation, the peripheral edge of the second housing has a hem, and the hem is used to snap onto the main body of the foldable electronic device. The connecting layer extends from the side of the second housing facing away from the foldable electronic device along the hem to the side of the second housing facing the foldable electronic device.

[0015] In this way, the risk of cracking of the soft glue layer during the overmolding process of the soft glue layer and the second housing and during the use of the protective case can be reduced.

[0016] In a possible implementation, the materials of the first housing and the second housing are both plastics, and the first housing and the second housing are formed with a soft glue layer by a two-shot injection molding process to connect the first housing and the second housing.

[0017] In this way, the soft glue layer and the first housing and the second housing are of the same material, which is beneficial to the overall appearance integrity of the protective case and improves the aesthetics of the protective case. Moreover, the manufacturing process of the protective case is simple, which is beneficial to the mass production of the protective case.

[0018] In a possible implementation, the protective case further includes: a magnetic member. An assembly groove is formed on the side of the first housing facing the foldable electronic device, and the magnetic member is assembled in the assembly groove.

[0019] The magnetic member can adsorb the rotating shaft mechanism of the foldable electronic device, which can simplify the operation of assembling the foldable electronic device into the protective case and improve the aesthetic degree of the appearance of the protective case.

[0020] In a possible implementation, the protective case further includes: a shielding member. The shielding member covers the assembly groove to shield the magnetic member and prevent the magnetic member from being exposed and affecting the aesthetics.

[0021] In a possible implementation, both the first housing and the second housing are one.

[0022] In a possible implementation, the first housing is one, and the second housing is two. The two second housings are respectively arranged on both sides of the first housing.

[0023] In a possible implementation, the foldable electronic device is a foldable mobile phone.

[0024] In a possible implementation, the thickness of the first extension layer and the second extension layer is between 0.75 mm and 0.85 mm.

[0025] On the other hand, the present application provides an electronic device, comprising: a foldable electronic device and the protective case as described above. The foldable electronic device includes: a rotating shaft mechanism and two main body parts. The two main body parts are respectively connected to both sides of the rotating shaft mechanism, and the two main body parts are relatively unfolded and folded through the rotating shaft mechanism. The first housing of the protective case is sleeved outside the rotating shaft mechanism, and the second housing of the protective case is sleeved outside the corresponding main body part.

[0026] In the electronic device provided by the embodiment of the present application, the protective case forms a soft glue layer to connect the first housing and the second housing by using an in-mold injection process. Without affecting the relative rotation of the first housing and the second housing, the thickness and composition of the soft glue layer can be adjusted to regulate the softness and hardness of the connection part between the first housing and the second housing, which is beneficial to improving the hand feeling and the user experience of consumers. Moreover, the soft glue layer formed by using the in-mold injection process can be well connected with the first housing and the second housing, which is beneficial to improving the shaping consistency. In addition, the assembly process of the first housing and the second housing can be reduced, and the assembly cost can be reduced, which is beneficial to the mass production of the protective case.

[0061] The terms used in the implementation manners part of this application are only used to explain the specific embodiments of this application, rather than intended to limit this application. The implementation manners of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] In the embodiments of this application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one" does not exclude the presence of additional identical elements in the process, method, article or device comprising that element.

[0063] An embodiment of this application provides an electronic device 100, which includes a foldable electronic device 200 and a protective case 300. The protective case 300 is used to be sleeved outside the foldable electronic device 200 to protect the foldable electronic device 200.

[0064] The foldable electronic device 200 provided in the embodiments of this application can be a mobile terminal such as a mobile phone, a tablet computer, a tablet computer accessory, a wearable device, a vehicle-mounted device, an Augmented Reality (AR) device, a Virtual Reality (VR) device, a notebook computer, an Ultra-mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), etc., or can also be a professional shooting device such as a digital camera, a single-lens reflex camera, a mirrorless camera, an action camera, a gimbal camera, a drone, etc. The embodiments of this application do not limit the specific type of the foldable electronic device 200, as long as it is an electronic device that realizes relative rotation of two main body parts through a rotating shaft mechanism. For the convenience of understanding, the embodiments of this application take the foldable electronic device 200 as a foldable mobile phone as an example for description.

[0065] Figure 1 FIG. is a schematic structural diagram of the folded state of the foldable electronic device 200 provided in an embodiment of this application. Figure 2 FIG. is a schematic structural diagram of the unfolded state of the foldable electronic device 200 provided in an embodiment of this application. Referring to Figure 1 and Figure 2 As shown, the foldable electronic device 200 provided in the embodiments of this application includes: a flexible screen 210, two main body parts 220, and a rotating shaft mechanism 230.

[0066] Specifically, the two main body parts 220 are respectively connected to both sides of the rotating shaft mechanism 230, and the rotating shaft mechanism 230 enables the two main body parts 220 to be relatively unfolded and folded. For a mobile phone, the main body part 220 can be a middle frame. It can be understood that the specific structure of the main body part 220 can be determined according to the specific electronic device, and the present application does not limit the specific structure of the main body part 220, and is not limited to the example where the main body part 220 is a middle frame as described above. Moreover, the structures of the two main body parts 220 can be the same, not completely the same, or completely different.

[0067] The flexible screen 210 is attached to the side where the two main body parts 220 are close to each other when folded. It can be understood that, from the perspective of the user's observation, when the foldable electronic device 200 is fully unfolded, the user faces the flexible screen 210, and the flexible screen 210 is attached to the upper surfaces of the two main body parts 220. During the relative unfolding and folding of the two main body parts 220, the flexible screen 210 is also unfolded and folded simultaneously with the two main body parts 220.

[0068] Among them, the flexible screen 210 can include: a display module and a transparent cover plate. The display module can display images, videos, etc. The display module can adopt a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light-emitting diode (QLED), etc. The transparent cover plate covers the side of the display module facing away from the inside of the electronic device, playing a role in protecting the display module. The transparent cover plate can be a glass cover plate, and of course, it can also be other transparent materials that can play a protective function. The flexible screen 210 can also have a touch function, that is, the flexible screen 210 can be a touch screen.

[0069] In some embodiments of the present application, the foldable electronic device 200 can further include: a shaft cover 240. The shaft cover 240 is covered on the side of the rotating shaft mechanism 230 facing away from the flexible screen 210, which can play a role in shielding the rotating shaft mechanism 230. On the one hand, it can improve the aesthetics of the appearance of the foldable electronic device 200, and on the other hand, it can protect the rotating shaft mechanism 230 to prevent the rotating shaft mechanism 230 from being damaged by external forces.

[0070] Figure 3Schematic structural diagram of the electronic device 100 provided by an embodiment of the present application. Refer to Figure 3 As shown, in the electronic device 100 provided by the embodiment of the present application, the protective case 300 includes: a first housing 310 and a second housing 320. The assembly manner of the foldable electronic device 200 and the protective case 300 is as shown by the dashed line in Figure 3 . The rotation shaft mechanism 230 is assembled to the first housing 310, the first housing 310 is sleeved outside the rotation shaft mechanism 230, the main body portion 220 is assembled to the second housing 320, and the second housing 320 is sleeved outside the corresponding main body portion 220. The protective case 300 plays a protective role in preventing scratching, falling, and shock of the foldable electronic device 200, has a dust-proof function, and can also decorate the appearance of the electronic device 100.

[0071] It should be noted that in the present application, "outside the foldable electronic device 200", "outside the rotation shaft mechanism 230", and "outside the main body portion 220" are all referenced based on the indicated orientation of the foldable electronic device 200 in daily life, that is, the side of the flexible screen 210 of the foldable electronic device 200 is the inside, and the side away from the flexible screen 210 is the outside.

[0072] Generally, the first housing 310 and the second housing 320 need to be set as an integral part to ensure the integrity of the protective case 300, facilitate consumers to carry and assemble, and prevent the loss of accessories of the protective case 300.

[0073] Figure 4 Partial structural cross-sectional schematic diagram of the protective case 10 in the related art. Refer to Figure 4 As shown, in the related art, the protective case 10 includes: a shaft cover shell 11 (corresponding to the first housing 310 in the embodiment of the present application) and a bottom shell 12 (corresponding to the second housing 320 in the embodiment of the present application). The shaft cover shell 11 and the bottom shell 12 are connected by pasting inner and outer PU skins 13.

[0074] However, this connection method between the shaft cover shell 11 and the bottom shell 12 has the following disadvantages: 1. The connection part between the shaft cover shell 11 and the bottom shell 12 (see the W section in Figure 4 ) is relatively hard, affecting the feel. 2. The shaping consistency of the PU skin 13 pasted on the surfaces of the shaft cover shell 11 and the bottom shell 12 is poor. For example, the shaft cover shell 11 is generally an arc-shaped housing. When the PU skin 13 is pasted on the surface of the shaft cover shell 11, on the one hand, the pasting operation is difficult, and on the other hand, it is easy to curl, affecting the shaping. 3. The assembly process of pasting the inner and outer PU skins 13 is complex, and the assembly cost is relatively high.

[0075] To solve the above problems, an embodiment of the present application provides a protective case 300. The soft glue layer 330 is formed by in-mold injection molding process to connect the first housing 310 and the second housing 320. In this process, the softness and hardness of the connection between the first housing 310 and the second housing 320 can be adjusted by adjusting the thickness and composition of the soft glue layer 330, so as to improve the feel of the protective case 300 and the user experience of consumers. Moreover, the shaping consistency between the soft glue layer 330 and the first housing 310 and the second housing 320 is good. In addition, the assembly process of connecting the first housing 310 and the second housing 320 can be reduced, and the assembly cost can be lowered.

[0076] The following will make a detailed description of the protective case 300 provided by the embodiment of the present application with reference to the accompanying drawings and specific embodiments.

[0077] Figure 5 It is a schematic structural diagram of the protective case 300 provided by an embodiment of the present application. Refer to Figure 5 As shown, the protective case 300 provided by the embodiment of the present application includes: a first housing 310 and a second housing 320. When the protective case 300 is used for the foldable electronic device 200, the first housing 310 is used to cover the outside of the rotating shaft mechanism 230 of the foldable electronic device 200, and the second housing 320 is used to cover the outside of the main body 220 of the foldable electronic device 200.

[0078] Among them, the present application does not limit the shapes, numbers and materials of the first housing 310 and the second housing 320.

[0079] Regarding the shapes of the first housing 310 and the second housing 320, for example Figure 5 As shown in, in some embodiments of the present application, the first housing 310 is in the shape of an arc groove to fit the shape of the rotating shaft mechanism 230 of the foldable mobile phone, and the second housing 320 is in the shape of a square groove to fit the shape of the main body 220 of the foldable mobile phone. It can be understood that, in other embodiments of the present application, the shapes of the first housing 310 and the second housing 320 can be arbitrarily adjusted according to the shapes of the corresponding objects to be protected.

[0080] Regarding the numbers of the first housing 310 and the second housing 320, for example Figure 5As shown, in some embodiments of the present application, the first housing 310 and the second housing 320 are each one, which can improve the aesthetic appearance of the electronic device 100. In some embodiments of the present application, the first housing 310 can be one, and the second housing 320 can be two. The two second housings 320 are respectively disposed on both sides of the first housing 310, and the two second housings 320 are respectively sleeved outside the main body portions 220 on both sides of the rotating shaft mechanism 230, which can provide comprehensive protection for the foldable electronic device 200. It can be understood that, in some other embodiments of the present application, the numbers of the first housing 310 and the second housing 320 can be arbitrarily adjusted according to the number of the corresponding objects to be protected. For example, the first housing 310 can be multiple, and the second housing 320 can also be multiple.

[0081] Regarding the materials of the first housing 310 and the second housing 320, plastics, metals, ceramics, etc. can be used. The materials of the first housing 310 and the second housing 320 can be the same or different.

[0082] The first housing 310 and the second housing 320 can be designed accordingly according to specific requirements. For example Figure 5 In, a camera opening 321 can be formed on the second housing 320. The camera opening 321 can avoid the camera module of the foldable mobile phone so that the camera module can take pictures and videos. The camera opening 321 can also be used as a decorative element to decorate the electronic device 100. A socket 322 can also be formed on the second housing 320 so that a data cable can pass through the second housing 320 to connect to the foldable electronic device 200, enabling the foldable electronic device 200 to perform charging and data transmission, etc. Among them, the shapes of the camera opening 321 and the socket 322 can be any shape according to requirements. Exemplarily, such as Figure 5 In, the camera opening 321 is square, and the socket 322 is a round hole and a trapezoidal notch.

[0083] Figure 6 For Figure 5 is a schematic cross-sectional structure diagram along the cutting line A-A in, Figure 7 For Figure 6 is a schematic enlarged view of the structure of part B in, refer to Figure 6 And Figure 7 As shown in and, for the protective case 300 provided by the embodiment of the present application, a soft glue layer 330 is formed between the first housing 310 and the second housing 320 by an in-mold injection process to connect the first housing 310 and the second housing 320. The first housing 310 and the second housing 320 are connected by the soft glue layer 330 and can rotate relative to each other.

[0084] It is understandable that the protective shell 300 provided in the embodiment of the present application connects the first shell 310 and the second shell 320 by forming a soft glue layer 330 through an in-mold injection molding process. Without affecting the relative rotation of the first shell 310 and the second shell 320, the thickness and composition of the soft glue layer 330 can be adjusted to adjust the softness and hardness of the connection between the first shell 310 and the second shell 320, which is beneficial to improving the feel of the protective shell 300 and the consumer's experience. In addition, the soft glue layer 330 formed by the in-mold injection molding process can be well connected with the first shell 310 and the second shell 320, which is beneficial to improve the consistency of shaping. In addition, the assembly process of the first shell 310 and the second shell 320 can be reduced, the assembly cost can be reduced, and it is beneficial to the mass production of the protective shell 300.

[0085] It should be noted that, for ordinary technicians in this field, without expending creative labor, the protective case 300 provided in the embodiment of the present application can also be applied to not limited to the foldable electronic device 200 as mentioned above, but can also be a foldable device (not necessarily an electronic device) or a non-folding electronic device, non-folding device, etc.

[0086] The present application does not limit the connection method between the soft glue layer 330 and the first shell 310 and the second shell 320. For example, the soft glue layer 330 can be formed between the first shell 310 and the second shell 320. Alternatively, the soft glue layer 330 can be formed on the side of the first shell 310 and the second shell 320 facing the foldable electronic device 200. Alternatively, the soft glue layer 330 can be formed on the side of the first shell 310 and the second shell 320 facing away from the foldable electronic device 200. Alternatively, the soft glue layer 330 can be formed on both the side of the first shell 310 and the second shell 320 facing the foldable electronic device 200 and the side of the first shell 310 and the second shell 320 facing away from the foldable electronic device 200. Alternatively, the soft glue layer 330 can be formed on the side of the first shell 310 facing away from the foldable electronic device 200 and the side of the second shell 320 facing the foldable electronic device 200. Alternatively, the soft glue layer 330 can be formed on the side of the first shell 310 facing the foldable electronic device 200 and the side of the second shell 320 facing the foldable electronic device 200. Alternatively, the soft glue layer 330 can be formed on the side of the first shell 310 facing the foldable electronic device 200 and the side of the second shell 320 facing away from the foldable electronic device 200.

[0087] Continue to refer Figure 7As shown, in some embodiments of the present application, the soft glue layer 330 includes a connection layer 331, and at least a part of the connection layer 331 is formed on the side of the first housing 310 and the second housing 320 facing away from the foldable electronic device 200. Compared with the way that the soft glue layer 330 is formed between the first housing 310 and the second housing 320, the connection stability between the first housing 310 and the second housing 320 can be improved. Compared with the way that the soft glue layer 330 is formed on the side of the first housing 310 and the second housing 320 facing the foldable electronic device 200, the aesthetic appearance of the protective shell 300 can be improved. Compared with the way that the soft glue layer 330 is formed on both the side of the first housing 310 and the second housing 320 facing the foldable electronic device 200 and the side of the first housing 310 and the second housing 320 facing away from the foldable electronic device 200, the single-layer soft glue layer 330 can enhance the user experience of consumers. Compared with the way that the soft glue layer 330 is formed on the side of the first housing 310 facing away from the foldable electronic device 200 and the side of the second housing 320 facing the foldable electronic device 200, and the soft glue layer 330 is formed on the side of the first housing 310 facing the foldable electronic device 200 and the side of the second housing 320 facing away from the foldable electronic device 200, the risk of tearing of the soft glue layer 330 during the relative rotation of the first housing 310 and the second housing 320 can be reduced.

[0088] The above "at least a part of the connection layer 331 is formed on the side of the first housing 310 and the second housing 320 facing away from the foldable electronic device 200" means that the connection layer 331 can be entirely formed on the side of the first housing 310 and the second housing 320 facing away from the foldable electronic device 200, or a part of the connection layer 331 is formed on the side of the first housing 310 and the second housing 320 facing away from the foldable electronic device 200.

[0089] Continue to refer to Figure 7 As shown, during the use of the protective shell 300, since the first housing 310 and the second housing 320 need to rotate relative to each other countless times, Figure 7 the soft glue layer 330 at the position indicated by the solid arrow in Figure 7 will be torn and debonded. To solve the above problems, refer to Figure 7 As shown, in some embodiments of the present application, the soft glue layer 330 further includes a first extension layer 332 integrally provided with the connection layer 331. The first extension layer 332 is disposed on the side of the second housing 320 close to the first housing 310, and the first extension layer 332 extends along the side wall of the second housing 320 to the side of the second housing 320 facing the foldable electronic device 200. In this way, the risk of tearing and debonding of the soft glue layer 330 at the position indicated by the solid arrow in

[0090] Similarly, in order to reduce the risk of tearing and delamination of the soft rubber layer 330 on the side of the first housing 310 (the probability of tearing and delamination of the soft rubber layer 330 on the side of the first housing 310 is relatively small), in some embodiments of the present application, the soft rubber layer 330 may further include a second extension layer (not shown in the figure) integrally provided with the connection layer 331. The second extension layer is disposed on the side of the first housing 310 close to the second housing 320, and the second extension layer extends along the side wall of the first housing 310 to the side of the first housing 310 facing the foldable electronic device 200. In this way, the overall service life of the protective case 300 can be improved.

[0091] Regarding the setting length of the first extension layer 332 on the side edge of the second housing 320 and the setting length of the second extension layer on the side edge of the first housing 310, the present application does not limit it. Exemplarily, as shown in Figure 5 In some embodiments of the present application, the first extension layer 332 may wrap a partial length of the side edge of the second housing 320 close to the first housing 310. Of course, according to the usage intensity of the protective case 300, the length of the first extension layer 332 along the side edge of the second housing 320 close to the first housing 310 can be lengthened, or the first extension layer 332 wraps the entire length of the side edge of the second housing 320 close to the first housing 310.

[0092] In some embodiments of the present application, the thickness of the first extension layer 332 and the second extension layer can be set between 0.75 mm and 0.85 mm. For example, the thickness of the first extension layer 332 and the second extension layer is set to 0.8 mm. From the results of multiple tests, setting the thickness of the first extension layer 332 and the second extension layer between 0.75 mm and 0.85 mm will neither affect the feel of the protective case 300 nor effectively prevent the soft rubber layer 330 from tearing and delaminating.

[0093] Continuing to refer to Figure 5 As shown in, in some embodiments of the present application, the peripheral edge of the second housing 320 may have a hem 323, and the hem 323 is used to snap onto the main body portion 220 of the foldable electronic device 200 so that the main body portion 220 of the foldable electronic device 200 can be assembled into the second housing 320. Of course, in some other embodiments of the present application, the main body portion 220 of the foldable electronic device 200 can also be assembled into the second housing 320 by a series of conventional installation methods such as magnetic attraction and adhesion.

[0094] During the overmolding process of the soft rubber layer 330 and the second housing 320 and during the use of the protective case 300, if the soft rubber layer 330 only covers the side of the second housing 320 facing away from the foldable electronic device 200, the soft rubber layer 330 is likely to crack.

[0095] To solve the above problems, Figure 8 ForFigure 5 Another perspective view of the protective case 300 shown in Figure 9 is Figure 8 a schematic cross-sectional structure diagram along the cutting line C-C in Figure 10 is Figure 9 a schematic enlarged view of the structure of part D in , referring to Figure 10 shown, in some embodiments of the present application, the connecting layer 331 extends from the side of the second housing 320 facing away from the foldable electronic device 200 along the fold edge 323 to the side of the second housing 320 facing the foldable electronic device 200. The thickness of the extending portion of the connecting layer 331 from the side of the second housing 320 facing away from the foldable electronic device 200 to the side of the second housing 320 facing the foldable electronic device 200 can be set between 0.75 mm and 0.85 mm. In this way, the risk of cracking of the soft glue layer 330 during the encapsulation process of the soft glue layer 330 and the second housing 320 and during the use of the protective case 300 can be reduced.

[0096] It can be understood that the setting area where the connecting layer 331 extends from the side of the second housing 320 facing away from the foldable electronic device 200 along the fold edge 323 to the side of the second housing 320 facing the foldable electronic device 200 can be set according to specific circumstances. For example, the setting area where the connecting layer 331 extends from the side of the second housing 320 facing away from the foldable electronic device 200 along the fold edge 323 to the side of the second housing 320 facing the foldable electronic device 200 can only cover a part of the fold edge 323. Or, the setting area where the connecting layer 331 extends from the side of the second housing 320 facing away from the foldable electronic device 200 along the fold edge 323 to the side of the second housing 320 facing the foldable electronic device 200 covers the entire fold edge 323.

[0097] In some embodiments of the present application, the first housing 310 and the second housing 320 can both be made of plastic material, and the first housing 310 and the second housing 320 are formed with the soft glue layer 330 by a two-shot injection molding process to connect the first housing 310 and the second housing 320. In this way, the soft glue layer 330 and the first housing 310 and the second housing 320 are of the same material, which is beneficial to the overall appearance integrity of the protective case 300 and improves the aesthetics of the protective case 300. Moreover, the manufacturing process of the protective case 300 is simple, which is beneficial to the mass production of the protective case 300.

[0098] Continue to refer to Figure 7As shown, in some embodiments of the present application, the protective case 300 may further include a magnetic member 340. An assembly groove 311 is formed on the surface of the first housing 310 facing the foldable electronic device 200, and the magnetic member 340 is assembled in the assembly groove 311. The magnetic member 340 can adsorb the rotating shaft mechanism 230 of the foldable electronic device 200, which can simplify the operation of assembling the foldable electronic device 200 in the protective case 300 and improve the aesthetic appearance of the protective case 300.

[0099] Wherein, the number of the magnetic members 340 can be one or more. For example, multiple magnetic members 340 are arranged in sequence along the length direction of the first housing 310.

[0100] Continue to refer to Figure 7 As shown, the protective case 300 may further include a shielding member 350. The shielding member 350 covers the assembly groove 311 to shield the magnetic member 340 and prevent the magnetic member 340 from being exposed and affecting the appearance. The shielding member 350 can be made of plastic, metal, etc.
