Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a protective case for a foldable screen electronic device. Background Technology

[0002] With the rapid development of technology, electronic devices such as mobile phones have gradually become essential tools for people to communicate, entertain themselves, and learn, basically covering various daily application scenarios. Currently, the display panel size of electronic devices is getting larger and larger to improve the user's viewing experience. However, excessively large electronic devices can be inconvenient for users to carry, so foldable screen electronic devices, as an emerging product, are widely loved by consumers.

[0003] Foldable electronic devices consist of an outer screen and an inner screen that are connected to each other. The back of the inner screen may contain features such as a camera. When needed, such as for watching videos, the outer and inner screens can be unfolded to provide a better user experience. When not in use, the outer and inner screens can be folded down to reduce the size of the electronic device for easy portability.

[0004] Protecting foldable electronic devices with protective cases can achieve the desired effect. However, since the outer screen needs to display images on both sides, most protective cases for foldable electronic devices use a frame structure for the outer screen, making it impossible to install a back panel. This structure is relatively weak. During daily use, the folding action may cause deformation of the frame structure, or even breakage, which will seriously affect the lifespan of the protective case and result in a poor user experience. Utility Model Content

[0005] In view of at least some of the problems and defects in the prior art, this utility model discloses a protective case for foldable screen electronic devices, so as to solve the problem that the frame structure of the outer screen of existing foldable screen electronic device protective cases is weak and is prone to deformation and breakage.

[0006] Specifically, the present invention provides a protective case for a foldable screen electronic device, comprising: a first housing, including a back plate and a first frame disposed around the back plate; a second housing, including a second frame, the second housing and the first housing together forming a housing portion for accommodating the foldable screen electronic device, the housing portion having a folding space at its center for folding the foldable screen electronic device; wherein the second housing further includes a reinforcing member, the reinforcing member being connected to the second frame and located at least on the side of the second housing near the folding space, the reinforcing member having a strength greater than the strength of the second frame.

[0007] The foldable screen electronic device protective case provided in this embodiment improves the external force that the second frame can withstand by setting a reinforcing member on the second frame. Since the yield strength of the reinforcing member is greater than the yield strength of the second frame, the external force that the second frame can withstand is increased. When the external force that the second frame can withstand is greater than the yield strength of the second frame, the second frame will not undergo permanent deformation, thus effectively improving the external force that the second frame can withstand and solving the problem that the second frame is easy to deform and break.

[0008] In one embodiment of the present invention, the second frame includes a bottom frame and a perimeter edge connected to the periphery of the bottom frame, and the reinforcing member is disposed on the bottom frame, or the reinforcing member is connected to the bottom frame.

[0009] In one embodiment of the present invention, a first groove is provided on the side of the bottom frame near the folding space, and the reinforcing member is fitted into the first groove.

[0010] In one embodiment of this utility model, the surrounding edge is a U-shaped structure formed by three interconnected edges, with the opening end located on the side of the second housing near the folding space, and the reinforcing member connected to the surrounding edge.

[0011] In one embodiment of this utility model, the reinforcing member is located at the opening end, and both ends of the reinforcing member are respectively connected to the surrounding edge, and the surrounding edge and the reinforcing member together form a ring structure.

[0012] In one embodiment of the present invention, the perimeter includes a first side, a second side, and a third side connected in sequence, and the reinforcing member includes a first reinforcing segment, a second reinforcing segment, and a third reinforcing segment that correspond to and are connected in sequence to the first side, the second side, and the third side, and a fourth reinforcing segment connected between the first segment and the third reinforcing segment, wherein the fourth reinforcing segment is located at the opening end to form a closed annular frame together with the perimeter.

[0013] In one embodiment of the present invention, the second frame is formed on the reinforcing member and forms an integral component with the reinforcing member. The reinforcing member is fixed inside the second frame as a whole, or both ends of the reinforcing member are fixed inside the second frame.

[0014] In one embodiment of the present invention, the second housing further includes a protective member, which corresponds to the reinforcing member and covers the surface of the reinforcing member near the receiving portion.

[0015] In one embodiment of the present invention, the protective member has an adhesive side away from the reinforcing member for bonding with the foldable screen electronic device.

[0016] In one embodiment of the present invention, a button avoidance portion is provided on the first frame, and the second housing is connected to the side of the first housing away from the button avoidance portion; or, the second housing is relatively separated from the first housing.

[0017] As can be seen from the above, the above-mentioned technical features of this utility model can have one or more of the following beneficial effects: The protective shell for foldable screen electronic devices provided in this embodiment, by setting a reinforcing member on the second shell, improves the external force that the second frame can withstand because the yield strength of the reinforcing member is greater than the yield strength of the second frame. When the external force borne by the second frame is greater than the yield strength of the second frame, the second frame will not undergo permanent deformation, effectively improving the external force that the second frame can withstand and solving the problem that the second frame is easy to deform and break.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] It should be noted that the directional terms mentioned in the embodiments of this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model. For the sake of understanding and ease of description, the dimensions and thicknesses of each component shown in the drawings are arbitrarily shown, but this utility model is not limited thereto.

[0030] It is understood that when a component, such as a layer, membrane, region, or substrate, is referred to as "on" another component, the component may be directly on the other component, or there may be intermediate components present. Furthermore, in the specification, unless explicitly stated otherwise, the word "comprising" will be understood to mean including the stated component, but not excluding any other components. Additionally, in the specification, "on" means located above or below the target component, and does not mean necessarily located on top of it based on gravity.

[0031] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] like Figure 1 and Figure 2 As shown, this embodiment of the present invention provides a protective case 10 for a foldable screen electronic device. The protective case 10 provided by this embodiment can be fitted onto the outside of a foldable screen electronic device to provide protection for the device, such as a foldable screen mobile phone.

[0033] For details, see Figure 1 and Figure 2 The protective case 10 for the foldable screen electronic device includes, for example, a first housing 100 and a second housing 200. Specifically, the first housing 100 includes, for example, a back panel 110 and a first frame 120 disposed around the periphery of the back panel 110. The second housing 200 includes, for example, a second frame 210. The second housing 200 and the first housing 100 together form a receiving portion 130 for accommodating the foldable screen electronic device. The second housing 200 is rotatable relative to the first housing 100. The receiving portion 130 has a folding space at its center for folding the foldable screen electronic device. For example, the first housing 100 is fitted onto the inner screen of the foldable screen electronic device, and the second housing 200 is fitted onto the outer screen of the foldable screen electronic device. The second housing 200 also includes a reinforcing member 220, which is connected to the second frame 210 and is located at least on the side of the second housing 200 near the folding space. The strength of the reinforcing member 220 is greater than the strength of the second frame 210. It should be noted that the first housing 100 and the second housing 200 can be relatively separated. When they are relatively separated, the folding space is located, for example, in the middle of the accommodating portion formed by the two and in the gap between the first housing 100 and the second housing 200. A connecting portion is also provided between the first housing 100 and the second housing 200 to connect them. Here, the folding space is located, for example, at the connection point between the two, i.e., at the location of the connecting portion. Further, for example, the material of the second frame 210 is, for example, silicone, thermoplastic polyurethane, or polycarbonate, and the material of the reinforcing member 220 is, for example, metal. This application does not specifically limit the materials of the second frame 210 and the reinforcing member 220. It should be noted that the strength mentioned above is the yield strength. The yield strength is the yield limit when a material yields. Under an external force greater than this limit, the part will undergo permanent deformation; under an external force less than this limit, the part will return to its original shape.

[0034] The protective case for foldable screen electronic devices provided in this embodiment improves the external force that the second frame can withstand by setting a reinforcing member on the second frame. Since the yield strength of the reinforcing member is greater than the yield strength of the second frame, the external force that the second frame can withstand is increased. When the external force that the second frame can withstand is greater than the yield strength of the second frame, the second frame will not undergo permanent deformation, which effectively improves the external force that the second frame can withstand and solves the problem that the second frame is easy to deform and break.

[0035] For details, see Figure 2The second frame 210 includes a bottom frame 211 and a perimeter 212 connected to the periphery of the bottom frame 211. The reinforcing member 220 is disposed on the bottom frame 211, or the reinforcing member 220 is connected to the bottom frame 211, for example. By providing the reinforcing member 220 on the bottom frame 211, the strength of the second frame 210 is improved, thereby preventing deformation of the second frame.

[0036] Further, see Figure 2 The bottom frame 211 has a first groove 2111 on its side near the folding space. The reinforcing member 220 is, for example, an elongated strip shape that matches this bottom edge, and the reinforcing member 220 is fitted into the first groove 2111. In this way, by providing the reinforcing member 220 on the side of the bottom frame 211 near the back plate 110, the structural strength at this location is improved, thereby suppressing the deformation and breakage risk of the second frame 210. For example, this fitting can be understood as the reinforcing member 220 and the first groove 2111 having a matching fitting structure, or the reinforcing member 220 and the second frame 210 being integrally formed or bonded together.

[0037] In one specific implementation, see Figure 3 The surrounding edge 212 is a U-shaped structure formed by three interconnected edges, with an open end 213 located on the side of the second housing 200 near the folding space. The reinforcing member 220 is connected to the surrounding edge 212. This design ensures that when the second housing 200 is fitted onto the outer screen, the open end 213 corresponds to the connection point between the outer and inner screens.

[0038] As stated above, see also Figure 3 The reinforcing member 220 is located, for example, at the opening end 213, and both ends of the reinforcing member 220 are connected to the surrounding edge 212. The surrounding edge 212 and the reinforcing member 220 together form a ring structure. In this way, not only is the structural strength of the second housing 200 increased, but it also makes it easier for users to operate the foldable screen electronic device.

[0039] In another implementation, see Figure 4The perimeter 212 includes a first side 214, a second side 215, and a third side 216 connected in sequence. The reinforcing member 220 includes a first reinforcing segment 221, a second reinforcing segment 222, and a third reinforcing segment 223 that correspond to and are connected in sequence to the first side 214, the second side 215, and the third side 216, respectively, and a fourth reinforcing segment 224 connected between the first reinforcing segment 221 and the third reinforcing segment 223. The fourth reinforcing segment 224 is located at the opening end 213 to form a closed annular frame together with the perimeter 212, for example, a rectangular frame. With this design, the reinforcing member 220, for example, covers the entire bottom frame 211 as an independent and complete reinforcing component, thereby further improving the overall structural strength of the second housing 200.

[0040] As described above, the second frame 210 is further provided with a connecting groove 217, and the reinforcing member is provided with a connecting protrusion 225. The connecting protrusion 225 engages with the connecting groove 217. The second frame 210 and the reinforcing member 220 are integrally formed, i.e., the second frame 210 is formed onto the reinforcing member 220 through an integral molding process such as injection molding, forming an integral component. Specifically, the reinforcing member 220 is fixed entirely inside the second frame 210, or both ends of the reinforcing member 220 are fixed inside the second frame 210. For example, see... Figure 2 When the reinforcing member 220 is embedded in the first groove 2111 of the base frame 211, the base frame 211 near the first groove 2111 is provided with, for example, two connecting grooves 217, and the two ends of the reinforcing member 220 are provided with connecting protrusions 225, which are respectively embedded in the two connecting grooves 217; or, see Figure 3 When the two ends of the reinforcing member 220 are connected to the surrounding edge 212 to form a ring structure, the surrounding edge 212 near the opening end 213 is provided with two connecting grooves 217, and the two ends of the reinforcing member 220 are provided with connecting protrusions 225, which are respectively embedded in the two connecting grooves 217. Alternatively, when the reinforcing member includes multiple reinforcing segments to be connected to the surrounding edge, the first reinforcing segment 221, the second reinforcing segment 222, and the third reinforcing segment 223 are respectively provided with connecting protrusions extending toward the surrounding edge (not shown in the figure), and the first side 214, the second side 215, and the third side 216 of the surrounding edge are respectively provided with connecting grooves extending away from the reinforcing segments and corresponding to the connecting protrusions 225 (not shown in the figure), which are respectively embedded in the corresponding connecting grooves. Preferably, the reinforcing member 220 and the second frame 210 are integrally formed, for example. This maximizes the connection strength between the reinforcing member 220 and the second frame 210, reducing the risk of the reinforcing member 220 falling off from the second frame 210.

[0041] See Figure 2 , Figure 3 and Figure 5 The second housing 200 further includes a protective member 230, which corresponds to the reinforcing member 220 and covers the surface of the reinforcing member 220 near the receiving portion 130. For example, the protective member 230 is attached to the surface of the reinforcing member 220 near the receiving portion 130. By providing the protective member 230, the aesthetics of the protective case for the foldable screen electronic device are improved, and the risk of the reinforcing member 220 falling off is reduced. Furthermore, the protective member 230 can prevent water, impurities in the air, sweat from hands, etc., from contacting the reinforcing member 220, effectively preventing oxidation and corrosion of the reinforcing member 220. It also prevents the reinforcing member 220 from directly contacting the electronic device. When the reinforcing member 220 is made of a hard material such as metal, it can effectively prevent the reinforcing member 220 from scratching the electronic device. As mentioned above, the side of the protective member 230 away from the reinforcing member 220 has adhesive properties for bonding to the foldable screen electronic device. This improves the connection strength between the protective cases 10 of the foldable screen electronic devices and prevents the foldable screen electronic devices from falling off the protective cases 10.

[0042] In addition, see Figure 1 The first frame 120 is provided with a button avoidance part 121, and the second housing 200 is connected to the side of the first housing 100 away from the button avoidance part 121; or, the second housing 200 is relatively separated from the first housing 100.

[0043] In summary, the protective case for foldable screen electronic devices provided in this embodiment improves the external force that the second frame can withstand by setting a reinforcing member on the second frame. Since the yield strength of the reinforcing member is greater than the yield strength of the second frame, the second frame will not undergo permanent deformation when the external force it withstands is greater than the yield strength of the second frame. This effectively improves the external force that the second frame can withstand and solves the problem that the second frame is easy to deform and break.
