[0040] See also Figure 1 As shown, the protective shell 10 provided in the embodiment of the utility model includes: a front shell 101 , a back shell 102 , a protective cover 20 and a connecting member 30 .
[0041] The connecting member 30 includes a first connecting portion 301, a movable portion 302 and a second connecting portion 303 which are arranged in sequence; the first connecting portion 301 is fixedly connected to the front shell 101, and the second connecting portion 303 is fixedly connected to the back shell 102. The protective cover 20 is fixed on the movable portion 302.
[0042] Among them, the connecting member 30 can be an elastic or non-elastic flexible material, such as cloth, leather, silicone material, etc. The fixing connection method between the first connecting part 301 and the face shell 101, and the second connecting part 303 and the back shell 102 can be gluing, hot melting, riveting, etc. Optionally, the first connecting part 301 is fixed on the inner surface of the face shell 101, and the second connecting part 303 is fixed on the inner surface of the back shell 102. By fixing the first connecting part 301 and the second connecting part on the inner surface of the face shell 101 and the back shell 102 instead of the outer surface, while making the protective shell 10 more beautiful as a whole, the first connecting part 301 and the second connecting part 303 are exposed to the outside and the influence is reduced, the stability of the fixing of the first connecting part 301 and the second connecting part 303 is improved, and the life of the protective shell 10 is guaranteed.
[0043] In the embodiment of the utility model, the protective cover 20 can be made of a material with a certain hardness. The protective cover 20 is used to effectively protect the area that cannot be covered by the front shell 101 and the back shell 102. For example, when the hinge structure of the electronic device is exposed due to the electronic device being folded, the protective cover 20 can cover the hinge structure for protection.
[0044] Among them, the front shell 101, the protective cover 20 and the back shell 102 are connected in sequence by the connecting member 30, so that the front shell 101, the back shell 102 and the protective cover 20 form a whole, so that when the electronic device is opened and closed, the protective cover 20 will follow the movement of the electronic device through the driving of the movable part 302, and the terminal device can be effectively protected in all directions when the folding screen electronic device is in the unfolded or folded state.
[0045] In the embodiment of the present application, the protective case 10 is used to be mounted on an electronic device. The electronic device can be a foldable electronic device, such as a foldable screen mobile phone, a foldable screen tablet computer, etc. The edge of the protective case 10 is formed with a groove that can be engaged with the edge of the electronic device, so as to facilitate the mounting of the electronic device.
[0046] Among them, taking the folding screen mobile phone as an example, Figure 2 A schematic cross-sectional structure diagram of the protective shell 10 provided in an embodiment of the present application in an unfolded state is shown; Figure 3 A schematic cross-sectional structure diagram of the protective shell 10 provided in an embodiment of the present application in a folded state is shown.
[0047] like Figure 3 As shown, when the electronic device is in a folded state, the movable portion 302 is unfolded to wrap the bending portion of the electronic device, and the protective cover 20 is covered on the movable portion 302. The bending portion of the electronic device may be a portion where a bending structure of the electronic device is located, wherein the bending structure may be a hinge structure of the electronic device, etc. When the bending structure is folded or unfolded, the entire electronic device is folded or unfolded accordingly.
[0048] By wrapping the movable part 302 and covering the protective cover 20, double protection is provided for the bending part of the electronic device, effectively preventing the bending part of the electronic device from being damaged when it falls or collides.
[0049] Correspondingly, if Figure 2 As shown, when the electronic device is in the unfolded state, the movable portion 302 is folded inside the protective cover 20 , the movable portion 302 is partially fixed on the inner side of the protective cover 20 , and the protective cover 20 is covered at the junction of the front shell 101 and the back shell 102 .
[0050] The junction of the front shell 101 and the back shell 102 refers to the area between one end of the front shell 101 close to the bending part and one end of the back shell 102 close to the bending part. The movable part 302 is folded into the protective cover 20, which can prevent the movable part 302 from affecting the electronic device and protect the movable part 302 from damage.
[0051] At the same time, the protective cover 20 is covered at the junction of the front shell 101 and the back shell 102 to strengthen the protection of the part of the electronic device that is not covered by the front shell 101 and the back shell 102.
[0052] Specifically, Figure 4 The schematic diagram of the structure of the connector 30 in the unfolded state of the protective shell provided by the embodiment of the present application is shown. Figure 5 The schematic diagram of the structure of the connecting member when the protective shell provided by the embodiment of the present application is in the folded state is shown. Figure 4 as well as Figure 5 As shown, the movable portion 302 includes a first folding portion 3021, a mounting portion 3022 and a second folding portion 3023; the first connecting portion 301, the first folding portion 3021, the mounting portion 3022, the second folding portion 3023 and the second connecting portion 303 are arranged in sequence.
[0053] like Figure 3 as well as Figure 5 As shown, when the electronic device is in a folded state, the first folding portion 3021 and the second folding portion 3023 unfold each other and wrap the bent portion of the electronic device, thereby providing protection for the bent portion of the electronic device.
[0054] like Figure 2 as well as Figure 4 As shown, when the electronic device is in the unfolded state, the first folding portion 3021 and the second folding portion 3023 are folded and stored in the protective cover 20;
[0055] The mounting portion 3022 is fixedly connected to the protection cover 20 .
[0056] The movable portion 302 is divided into a first folding portion 3021, a mounting portion 3022 and a second folding portion 3023, wherein the first folding portion 3021 and the second folding portion 3023 are driven by the first connecting portion 301 and the second connecting portion 303 fixed to the front shell 101 and the back shell 102, and are correspondingly unfolded or folded according to the movement of the electronic device, thereby achieving effective protection for the bending portion, and when the bending portion does not need to be protected, it can be stored in the protective cover 20, thereby increasing the life of the protective shell 10 and not affecting the normal use of the electronic device.
[0057] Correspondingly, Figure 6 20 is a schematic diagram showing the structure of the protective cover 20. In order to make the protective cover 20 cover the bent part more closely, while simplifying the size of the protective shell 10, the protection strength of the electronic device is guaranteed. Figure 2-Figure 3 as well as Figure 6 As shown, the protection cover 20 includes a cover bottom 202 and a cover wall 203 surrounding and fixed on the four sides of the cover bottom 202 ; there is an arc transition between the cover wall 203 and the cover bottom 202 .
[0058] The cover wall 203 and the cover bottom 202 are enclosed into a groove structure to better accommodate the bent portion. At the same time, the arc transition between the cover wall 203 and the cover bottom 202 makes it easier for the protective cover 20 to match the outer edge shape of the bent portion of the electronic device. At the same time, the appearance of the protective cover 20 is more beautiful and less likely to scratch the user.
[0059] In the embodiment of the present application, a fixing groove 201 is provided on a surface of the protection cover 20 facing the connecting member 30; the mounting portion 3022 is fixedly disposed in the fixing groove 201. Figure 6 As shown, by providing the upper fixing groove 201 on the protective cover 20 to provide for the installation portion 3022, it is different from merely fixing the installation portion 3022 on the surface of the protective cover 20, so that the connection between the protective cover 20 and the connecting member 30 can be more stable, ensuring that the protective cover 20 will not be separated from the connecting member 30. Specifically, the installation portion 3022 can be fixed in the fixing groove 201 by means of snapping, gluing, hot melting, riveting, etc. Figure 4 As shown, a plurality of through holes for installation may be provided on the installation portion 3022. The depth of the fixing groove 201 may be adaptively set according to the thickness of the installation portion 3022, and the shape and size of the fixing groove 201 may be adaptively set according to the shape and size of the installation portion 3022, so that the fixing groove 201 can accommodate the installation portion 3022 more closely.
[0060] Optionally, Figure 7 FIG. 1 is a schematic diagram showing the structure of a protective shell 10 provided in another embodiment of the present application. The protective shell 10 in this embodiment further includes a fixing plate 40; Figure 7 As shown, the fixing plate 40 is disposed on a side of the movable portion 302 away from the protective cover 20;
[0061] The mounting portion 3022 is fixed in the fixing groove 201 through the fixing plate 40 .
[0062] Specifically, Figure 7 As shown, the fixing plate 40 is provided with through holes at positions corresponding to the through holes on the mounting portion 3022. When installing the mounting portion 3022, the mounting portion 3022 is placed in the fixing groove 201, the fixing plate 40 is stacked on the outside of the mounting portion 3022, and the fixing members such as rivets are fixed to the mounting holes of the mounting portion 3022 and the fixing plate 40, so that the fixing plate 40 and the mounting portion 3022 are fixed together in the fixing groove 201. It can be understood that, in order to facilitate the installation of the mounting portion 3022, as shown in Figure 6, a plurality of concave holes can also be correspondingly provided in the fixing groove 201 so that the fixing members can be embedded and fixed.
[0063] Furthermore, considering that the fixing plate 40 and the mounting portion 3022 have a certain thickness, they may protrude from the protective cover 20 and thus press against the bending portion, affecting the normal use of the electronic device. Therefore, the depth of the fixing groove 201 is greater than or equal to the sum of the thickness of the mounting portion 3022 and the fixing plate 40, so as to reserve a buffer space between the fixing plate 40 and the bending area to prevent the fixing plate 40 from pressing against the bending portion when the terminal device is folded. At the same time, the buffer space can also provide buffer protection for the electronic device when it falls or is hit.
[0064] Furthermore, considering that the fixing plate 40 is provided with fixing parts and mounting holes, its surface may be uneven and unsightly, and when the fixing plate 40 directly contacts the outside of the electronic device, friction loss may be caused to the outside of the electronic device, the fixing plate 40 is covered with a covering portion 50 on the side facing away from the mounting portion 3022.
[0065] On the one hand, the covering portion 50 covers the fixing plate 40, making the inner surface of the protective shell 10 more beautiful and improving the user experience. On the other hand, the covering portion 50 can provide appropriate buffering between the fixing plate 40 and the bending part of the electronic device, further enhancing the protection of the protective shell 10 for the electronic device.
[0066] Specifically, the covering portion 50 may be made of an elastic or non-elastic flexible material, such as cloth, leather, silicone material, etc.
[0067] Furthermore, considering that the front shell 101 and the back shell 102 may be subjected to different forces due to size inconsistency and other reasons when they move relative to each other, in order to improve the usability of the protective shell 10 and avoid damage to the movable part 302 due to inconsistent forces at both ends of the movable part 302, the fixing groove 201 is arranged in the middle position of the protective cover 20; the first folding part 3021 and the second folding part 3023 are symmetrically arranged at both ends of the movable part 302.
[0068] The fixing groove 201 is arranged in the middle of the protective cover 20 , and the first folding portion 3021 and the second folding portion 3023 are symmetrically arranged on the movable portion 302 , so that the forces on both sides of the mounting portion 3022 are relatively uniform, thereby preventing the mounting portion 3022 from detaching from the protective cover 20 .
[0069] Optionally, the mounting portion 3022 is fixed in the fixing groove 201 by adhesive material or by hot melting.
[0070] The mounting portion 3022 is fixed to the fixing groove 201 by adhesive material or by hot melting without the need for a fixing plate 40 , thereby reducing costs and the weight of the protective shell 10 , making it easier for users to use.
[0071] The protective shell 10 provided in the embodiment of the present application includes a front shell 101, a back shell 102, a protective cover 20 and a connecting member 30; wherein the connecting member 30 includes a first connecting portion 301, a movable portion 302 and a second connecting portion 303 arranged in sequence; the first connecting portion 301 is fixedly connected to the front shell 101, and the second connecting portion 303 is fixedly connected to the back shell 102; the protective cover 20 is fixed on the movable portion 302, and the front shell 101, the protective cover 20 and the back shell 102 are connected in sequence through the connecting member 30, so that the front shell 101, the back shell 102 and the protective cover 20 are integrated into one body. When the folding screen electronic device is in the folded state, the protective cover 20 can effectively protect the relatively fragile bending parts of the folding screen electronic device. Combined with the protective effects of the front shell and the back shell, when the folding screen electronic device is in the unfolded and folded states, the embodiment of the present application can provide effective and comprehensive protection for the folding screen electronic device.
