Technical Field

[0001] This application relates to the field of electronic device accessories technology, and in particular to a protective case. Background Technology

[0002] Electronic devices such as mobile phones and laptops are usually protected by protective cases. These cases typically include a cavity to house the electronic device; when in use, the case encloses part of the device, providing protection. The protective ability of a protective case is positively correlated with its thickness; the thicker the case, the stronger the protection. However, increasing the thickness of the case increases the overall size and weight of the electronic device, affecting the user's grip. Utility Model Content

[0003] To address the aforementioned technical problems, this application proposes a protective shell that enhances its protective capabilities without increasing the overall thickness of the protective shell.

[0004] This application provides a protective shell, the protective shell comprising: a frame, the frame including a corner portion, a first side portion extending along a first direction, and a second side portion extending along a second direction, the corner portion being disposed at the end of the first side portion in the first direction and / or the end of the second side portion in the second direction; the corner portion, the first side portion, and the second side portion enclosing a receiving cavity, the receiving cavity being configured to house an electronic device; along a third direction, the corner portion protrudes at least toward the front end of the protective shell from the first side portion and / or the second side portion; at least a portion of the corner portion protrudes away from the outer surface of the receiving cavity from the outer surface of the first side portion and / or the outer surface of the second side portion; the first direction and the second direction are intersecting, and the third direction is perpendicular to the first direction and the second direction.

[0005] The beneficial effects of this application's technical solution are as follows: the frame of the protective shell has a corner portion at the end of its side portion (at least one side portion), and the corner portion is located in the extension direction of the corresponding side portion, so that the corner portion and the side portion enclose a receiving cavity for accommodating an electronic device; wherein, the corner portion protrudes from the front end of the protective shell (the front end usually corresponds to the control display surface of the electronic device facing the user) in a direction perpendicular to the extension direction of the corresponding side portion, so that the corner portion can contact the contact object at the front end before the electronic device located in the corresponding side portion and frame in this vertical direction, thereby buffering the force of the contact object on the corresponding side portion and the electronic device; and at least a portion of the outer side surface of the corner portion protrudes from the outer side surface of the corresponding side portion, so that the corner portion can contact the contact object before the contact object relative to the outer side surface of the corresponding side portion, thereby buffering the force of the contact object on the side portion and the electronic device along the thickness direction of the corresponding side portion; and in this embodiment, the side portion serves as the main body of the protective shell, and its thickness is not increased, so the overall thickness of the protective shell is not increased. Therefore, through the above methods, this application can improve the protective capability of the protective case for electronic devices without increasing the overall thickness of the protective case.

[0023] Example Group 1

[0024] like Figures 1 to 8 As shown, the protective shell (not shown) includes a frame 10, which includes a corner portion 11, a first side portion 12 extending along a first direction x, and a second side portion 13 extending along a second direction y. The corner portion 11 is located at the end of the first side portion 12 in the first direction x and / or the end of the second side portion 13 in the second direction y. The corner portion 11, the first side portion 12, and the second side portion 13 surround and form a receiving cavity 14, which is configured to house an electronic device. Along a third direction z, the corner portion 11 protrudes at least toward the front end of the protective shell from the (corresponding) first side portion 12 and / or second side portion 13, and at least a portion of the corner portion 11 protrudes away from the outer surface of the receiving cavity 14 from the outer surface of the (corresponding) first side portion 12 and / or second side portion 13. The first direction x and the second direction y intersect, and the third direction z is perpendicular to the first direction x and the second direction y.

[0025] The front end of the protective casing refers to the end of the electronic device that faces the user when it is mounted in the casing. Typically, the control display surface of an electronic device needs to be exposed for user operation and viewing, and is easily damaged by contact or impact.

[0026] The corner portion 11 being provided at the end of the first side portion 12 in the first direction x and / or the end of the second side portion 13 in the second direction y means that at least one of the ends of the first side portion 12 in the first direction x and the second side portion 13 in the second direction y is provided with a corner portion 11. For example, when both the end of the first side portion 12 and the end of the second side portion 13 are provided with corner portions 11, they can share the same corner portion 11, that is, the corner portion 11 connects the first side portion 12 and the second side portion 13. For example, the corner portion 11 can also be provided at the end of the first side portion 12 away from the second side portion 13 and / or at the end of the second side portion 13 away from the first side portion 12.

[0027] Wherein, the corner portion 11 protruding at least toward the front end of the protective shell along the third direction z of the corresponding first side portion 12 and / or second side portion 13 means that the corner portion 11 at the end of the first side portion 13 protrudes at least toward the front end of the protective shell of the corresponding first side portion 12, and the corner portion 11 at the end of the second side portion 13 protrudes at least toward the front end of the protective shell of the corresponding second side portion 13.

[0028] Wherein, at least a portion of the corner portion 11 protrudes from the outer side of the receiving cavity 14 and from the outer side of the corresponding first side portion 12 and / or the outer side of the second side portion 13, meaning that at least a portion of the corner portion 11 at the end of the first side portion 13 protrudes from the outer side of the receiving cavity 14 and from the outer side of the corresponding first side portion 12, and at least a portion of the corner portion 11 at the end of the second side portion 13 protrudes from the outer side of the receiving cavity 14 and from the outer side of the corresponding second side portion 13.

[0029] The first direction x and the second direction y can be perpendicular, so that the first side portion 12 and the second side portion 13 are perpendicular to each other, to match a square electronic device. Alternatively, the first direction x and the second direction y can not be perpendicular, to match an electronic device of a corresponding shape.

[0030] The number of first side portions 12 and second side portions 13 is two, but not limited to two. In this embodiment, the frame 10 includes two first side portions 12 and two second side portions 13, with the first direction x, the second direction y, and the third direction z perpendicular to each other. In this embodiment, at least one first side portion 12 is connected to an adjacent second side portion 13 through a corner portion 11.

[0031] In this embodiment, the frame 10 of the protective shell has a corner portion 11 at the end of its side portion (first side portion 12 and / or second side portion 13), and the corner portion 11 is located in the extension direction (first direction x or second direction y) of the corresponding side portion, so that the corner portion 11 and the corresponding side portion form a receiving cavity 14 for accommodating the electronic device; wherein, the corner portion 11 is provided to protrude from the corresponding side portion in a direction perpendicular to the extension direction of the corresponding side portion (third direction z) toward the front end of the protective shell (the front end usually corresponds to the control display surface of the electronic device facing the user), so that the corner portion 11 can be positioned relative to the corresponding side portion in this vertical direction. The electronic device within the edge and frame 10 first contacts the contact object at the front end, thereby buffering the force exerted by the contact object on the corresponding side and the electronic device. Furthermore, at least a portion of the corner portion 11 protrudes from the outer surface of the receiving cavity 14, extending beyond the outer surface of the corresponding side portion, i.e., protruding along the thickness direction of the corresponding side portion. This allows the corner portion 11 to contact the contact object before the outer surface of the corresponding side portion, thereby buffering the force exerted by the contact object along the thickness direction of the corresponding side portion on the side and the electronic device. In this embodiment, the side portion serves as the main body of the protective shell, and its thickness is not increased; therefore, the overall thickness of the protective shell is not increased. Thus, through the above methods, this embodiment can improve the protective capability of the protective shell for the electronic device without increasing the overall thickness of the protective shell.

[0032] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the corner portion 11 connects the end of the first side portion 12 and the end of the second side portion 13. The corner portion 11 includes a first protrusion 111 and a second protrusion 112 connected along a third direction z. The first protrusion 111 is disposed near the front end of the protective shell relative to the second protrusion 112. The side of the first protrusion 111 opposite to the second protrusion 112 protrudes from the (corresponding) first side portion 12 and second side portion 13. At least a portion of the second protrusion 112 opposite to the outer side of the receiving cavity 14 protrudes from the (corresponding) outer side of the first side portion 12 and the outer side of the second side portion 13. In this way, the same corner portion 11 can simultaneously protrude to the front end of the protective shell relative to the first side portion 12 and the second side portion 13 connected to it, and protrude from the outer side of the first side portion 12 and the outer side of the second side portion 13, which simplifies the structure and reduces the overall weight of the protective shell. Meanwhile, after the electronic device is installed, the side of the second protrusion 112 facing the receiving cavity 14 creates a gap area between the side of the electronic device and the side of the electronic device. The gap area is filled with air, so the gap area can buffer the electronic device to a certain extent.

[0033] The outer side of the aforementioned side portion refers to the side portion that is away from the receiving cavity 14.

[0034] In other embodiments, a similar structure may be used when the corner portion 11 is located in other positions of the protective shell.

[0035] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the corner portion 11 also includes a third protrusion 113 connected along a third direction z to the side of the second protrusion 112 opposite to the first protrusion 111; the side of the third protrusion 113 opposite to the second protrusion 112 protrudes from the first side portion 12 and the second side portion 13.

[0036] In this embodiment, at least a portion of the corner portion 11 can protrude to the rear end of the protective shell relative to the first side portion 12 and the second side portion 13 connected thereto, so that the corner portion 11 can contact the contact object at the rear end relative to the electronic device disposed in the corresponding side portion and the frame 10 in the vertical direction (third direction z), thereby buffering the force of the contact object on the corresponding side portion and the electronic device, thereby improving the protective ability of the protective shell to protect the electronic device.

[0037] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the outer surfaces of the first protrusion 111 and the second protrusion 112 facing away from the receiving cavity 14 are both arc-shaped. In this way, not only can the aesthetics of the protective shell be improved, but the volume of the protective shell can also be reduced, avoiding or improving the problem of interference between the corner areas of the protective shell and external objects, thereby reducing the problem of collision with external objects.

[0038] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 As shown, the outer surface of the third protrusion 113 facing away from the receiving cavity 14 can also be arranged in an arc shape.

[0039] In some embodiments, the shape of the outer surface of the corner portion 11 may be adjusted based on the shape of the electronic device and other requirements.

[0040] In some embodiments, such as Figure 1 , Figure 6 , Figure 7 , Figure 8As shown, the first side portion 12 and / or the second side portion 13 includes a first edge portion 131, a side portion 132, and a second edge portion 133 connected sequentially along a third direction z; wherein the first edge portion 131 and the second edge portion 133 are inclined relative to the side portion 132 toward the receiving cavity 14; the end of the first edge portion 131 is connected to the first protrusion 111, the end of the side portion 132 is connected to the second protrusion 112, and the end of the second edge portion 133 is connected to the third protrusion 113; wherein the first protrusion 111 and the third protrusion 113 are inclined relative to the second protrusion 112 toward the receiving cavity 14.

[0041] In this embodiment, both the first side portion 12 and the second side portion 13 include a first edge portion 131, a side body portion 132, and a second edge portion 133 connected sequentially along a third direction z. In other embodiments, only the first side portion 12 or only the second side portion 13 may include the first edge portion 131, the side body portion 132, and the second edge portion 133.

[0042] Wherein, along the first direction x, the end of the first edge portion 131 of the first side portion 12 is connected to the end of the first protrusion 111, the end of the side portion 132 of the first side portion 12 is connected to the end of the second protrusion 112, and the end of the second edge portion 133 of the first side portion 12 is connected to the end of the third protrusion 113; along the second direction y, the end of the first edge portion 131 of the second side portion 13 is connected to the other end of the first protrusion 111, the end of the side portion 132 of the second side portion 13 is connected to the other end of the second protrusion 112, and the end of the second edge portion 133 of the second side portion 13 is connected to the other end of the third protrusion 113.

[0043] In this embodiment, the first edge portion 131 is inclined relative to the side portion 132 toward the receiving cavity 14, so that when the electronic device is mounted in the protective shell, the first edge portion 131 can extend to the front surface of the electronic device (i.e., the surface facing the user in use), thereby improving the binding effect of the protective shell on the electronic device and thus improving the protection capability of the electronic device. The second edge portion 133 is inclined relative to the side portion 132 toward the receiving cavity 14, which not only improves the aesthetics of the protective shell, but also reduces the volume of the protective shell, improves the problem of interference between the protective shell and external objects, and thus reduces the problem of collision with external objects. Furthermore, the first protrusion 111 and the third protrusion 113 are inclined relative to the second protrusion 112 toward the receiving cavity 14, which can improve the binding force of the corner portion 11 on the electronic device and the aesthetics, and reduce the volume of the protective shell.

[0044] In some embodiments, along the third direction z, the size of the second protrusion 112 is smaller than the size of the side portion 132.

[0045] Along the third direction z, the size of the first protrusion 111 is greater than the size of the first edge portion 131, and the size of the third protrusion 113 is greater than the size of the second edge portion 133.

[0046] For example, the corner portion 11 can be formed through hot pressing or other processes, so as not to increase the thickness of the protective shell and to form a protrusion of the corner portion 11. Of course, the corner portion 11 can also be formed through injection molding, cutting or other processes, or other similar corner portions 11 can be formed through hot pressing, injection molding or cutting or other processes.

[0047] In some embodiments, such as Figures 2 to 8 As shown, the protective shell also includes: a base plate 20, disposed on the side of the frame 10 in the third direction z, and a camera mounting portion 21 is provided on the base plate 20; the frame 10 includes at least a corner portion 11 disposed near the camera mounting portion 21 and another corner portion 11 disposed away from the camera mounting portion 21; and the other corner portion 11 disposed away from the camera mounting portion 21 is also provided with a third protrusion 113; wherein, the third protrusion 113 is connected along the third direction z to the side of the second protrusion 112 away from the first protrusion 111, and the side of the third protrusion 113 away from the second protrusion 112 protrudes from the first side portion 12 and the second side portion 13; the corner portion 11 disposed near the camera mounting portion 21 is only provided with the corresponding first protrusion 111 and second protrusion 112.

[0048] The base plate 20 and the frame 10 together form a receiving cavity 14. By setting the base plate 20, the protective ability of the protective shell to protect electronic devices can be improved; and when the electronic device is assembled in the protective shell, the base plate 20 is located on the back of the electronic device to improve the protection of the back of the electronic device and the overall binding force. The camera mounting portion 21 is typically provided to protrude from the side portion 12 along the third direction z. The camera mounting portion 21 can buffer the force applied to the electronic device from the back of the protective shell. Therefore, the corner portion 11 near the camera mounting portion 21 only has corresponding first protrusion 111 and second protrusion 112, which can reduce the weight of the protective shell and simplify its structure and process. Furthermore, the corner portions 11 at other positions are also provided with third protrusion 113. At least a portion of the corner portion 11 can protrude to the rear end of the protective shell relative to the first side portion 12 and the second side portion 13 connected to it, so that the corner portion 11 can contact the contact object at the rear end relative to the electronic device located in the corresponding side portion and frame 10 in the vertical direction (third direction z), thereby buffering the force of the contact object on the corresponding side portion and electronic device, and thus improving the protective ability of the protective shell to protect the electronic device.

[0049] In some embodiments, a third protrusion 113 may also be provided at the corner near the camera mounting portion 21, and the camera mounting portion protrudes from the receiving cavity 14 along a third direction z from the third protrusion 113 near the camera mounting portion 21; the structure of the third protrusion 113 can be referred to the above embodiments.

[0050] In this embodiment, the third protrusion 113 can form a double layer of protection with the camera mounting part 21.

[0051] In some embodiments, such as Figures 2 to 8 As shown, the frame 10 of this embodiment includes two first side portions 12 and two second side portions 13, and the first direction x, the second direction y, and the third direction z can be perpendicular to each other; the frame 10 includes a corner portion 11, and each corner portion 11 is connected to a first side portion 12 and a second side portion 13 at both ends, respectively. The two ends of the first side portion 12 are connected to different corner portions 11, and the two ends of the second side portion 13 are connected to different corner portions 11. In this way, the protective capability of the protective case for electronic devices can be further improved.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, a buffer cavity 15 is provided on the side of the corner portion 11 near the receiving cavity 14. The buffer cavity 15 can form an airbag, which can buffer the external force on the corner portion 11, thereby further improving the protective ability of the protective shell to protect electronic devices.

[0053] In some embodiments, the corner portion 11 protrudes outward to form the second protrusion 112, and the side of the second protrusion 112 facing the receiving cavity 14 forms the buffer cavity 15. The buffer cavity 15 may be formed by the second protrusion 112 protruding outward, that is, the aforementioned interval region.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the buffer cavity 15 is located inside the second protrusion 112. Because the second protrusion 112 protrudes further outward toward the outer side of the frame 10, this structure can increase the volume of the buffer cavity 15 and improve the buffering effect.

[0055] The buffer cavity 15 and the second protrusion 112 can be formed simultaneously through a stamping process; this method does not increase the thickness of the corner portion 11.

[0056] When the protective shell is installed on the electronic device, the buffer cavity 15 is maintained between the four corners of the protective shell and the electronic device. When the four corners are impacted, the buffer cavity 15 forms an airbag and also provides deformation space for the protective shell, so that the protective shell can absorb the impact energy at this position and play a buffering role.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the buffer cavity 15 is connected to the receiving cavity 14. In this way, the thickness of the corner portion 11 can be reduced and its deformation capacity can be improved; and the manufacturing process can be simplified.

[0058] In some embodiments, the buffer cavity 15 may not be in communication with the receiving cavity 14, or the buffer cavity 15 may be filled with buffering material, etc.

[0059] The shape, number, and position of the buffer cavity 15 may, but are not limited to, correspond to the second protrusion 112.

[0060] In some embodiments, such as Figure 9 As shown, a buffer heat-conducting layer (not shown) is provided on the side of the base plate 20 near the receiving cavity 14 to further improve the protective ability of the protective shell for electronic devices and improve the heat dissipation ability of electronic devices.

[0061] In some embodiments, a buffer heat-conducting layer (not shown) may also be provided on the side of the frame 10 near the receiving cavity 14 to further improve the protective ability of the protective shell for electronic devices and improve the heat dissipation capability of electronic devices.

[0062] In some embodiments, the thermally conductive buffer layer may be a silicone TPU (thermoplastic polyurethane) layer or a hydrogel film layer, etc.

[0063] In some embodiments, such as Figure 9 As shown, the base plate 20 has an outer shell layer 22, an intermediate layer 211 and an inner liner layer 23 stacked in sequence; the intermediate layer 211 is provided with a receiving hole 24, which contains a magnet 25, so that it can be attracted to the electronic device when the electronic device is assembled in the protective shell, thereby increasing the binding force on the electronic device.

[0064] In some embodiments, the intermediate layer 211 includes a glass fiber resin composite layer; the inner liner 23 includes a TPU layer, and the inner liner 23 is provided with a buffer thermal conductive layer on the side facing the receiving cavity 14, or the inner liner 23 includes a buffer thermal conductive layer.

[0065] In some embodiments, the outer shell layer 22 may be injection molded from TPU, with an aramid fiber layer (not shown) attached to its outer surface; the intermediate layer 211 may be formed from a glass fiber and resin composite material. The inner liner layer 23 may be made of TPU, with a thermally conductive buffer layer disposed on the side of the inner liner layer 23 facing the electronic device; or the inner liner layer 23 may be a thermally conductive buffer layer directly, for example, using a hydrogel film.

[0066] In some embodiments, the outer shell layer 22 may be formed using a die-casting process.

[0067] In some embodiments, such as Figure 2 and Figure 4 As shown, the bottom of the base plate 20 is equipped with a hook 70 for easy connection with a hanging rope.

[0068] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the second side portion 13 is also provided with a decorative part 60, a button part 50 and other structures.

[0069] In some embodiments, the thickness of the outer shell layer 22 can be from 1.5 mm to 1.7 mm. Specifically, the thickness can be 1.5 mm, 1.55 mm, 1.6 mm, 1.65 mm, or 1.7 mm.

[0070] Example Group 2

[0071] In this embodiment, as Figure 8 As shown, based on Embodiment 1, the protective shell includes a base plate 20 and a frame 10. The protective shell also includes a button, which corresponds to a touch-sensitive sliding button on an electronic device. The user can slide or press the button to interact with the touch-sensitive sliding button on the electronic device. The button is flexible and easily deformable, allowing for accurate feedback of the finger's pressing or sliding motion to the touch-sensitive button on the electronic device. The button can be located on the base plate 20, the frame 10, or other locations on the electronic device.

[0072] In some embodiments, the button is disposed on the base plate 20; the button and the base plate 20 are an integral structure, i.e., integrally formed. Furthermore, the button and the base plate 20 may be made of the same material and integrally formed on the base plate 20.

[0073] In some embodiments, the button is disposed on the frame 10; the button and the frame 10 are an integral structure, i.e., integrally formed. Furthermore, the button and the frame 10 may be made of the same material and integrally formed on the frame 10.

[0074] In some embodiments, the button is formed by changing the thickness of a local area of ​​the protective shell; by reducing the thickness of a local area of ​​the protective shell, the flexibility of the material at the reduced thickness location is increased, so that it meets the requirements for being a button.

[0075] In some embodiments, the thickness of the button is 0.4 mm to 0.5 mm. Specifically, the thickness can be 0.4 mm, 0.45 mm, or 0.5 mm.

[0076] In some embodiments, the protective case frame is made of TPU material, the button is formed on the frame of the protective case, and the thickness of the button is 0.4mm to 0.5mm. Specifically, the thickness can be 0.4mm, 0.45mm, or 0.5mm.

[0077] In some embodiments, pressing the button causes the inner surface of the button to contact the corresponding touch sliding button of the electronic device, thereby transmitting a finger movement signal. To facilitate the user pressing the button, the button includes a first button portion 30 and a flexible connecting portion 121. The first button portion 30 is connected to the frame 10 through the flexible connecting portion 121. The first button portion 30 and the frame are not located on the same plane. More specifically, the first button portion 30 is recessed relative to the outer surface of the frame 10 in the direction toward the receiving cavity 14. Preferably, both the first button portion 30 and the flexible connecting portion 121 are formed on the frame 10 and can be integrally molded onto the frame 10 by injection molding. Both the first button portion 30 and the flexible connecting portion 121 can be made of TPU material, and their thicknesses can be the same, both being 0.4mm to 0.5mm. In other embodiments, in order to increase the flexibility of the button, the thickness of the flexible connecting portion 121 is thinner than that of the first button portion 30. In order for the button to return to its shape after the pressure is removed, the flexible connecting portion 121 and the first button portion 30 are elastic, and the elastic modulus of the flexible connecting portion 121 and the first button portion 30 is less than that of the frame 10. This can be achieved by reducing the thickness of the TPU at the button portion position.

[0078] In some embodiments, the first button portion 30 is recessed relative to the outer surface of the frame 10 by a first distance. Preferably, the first distance is 0.8 mm to 1.2 mm along the thickness direction perpendicular to the frame 10. Specifically, the first distance can be 0.9 mm, 0.9 mm, 1.0 mm, 1.1 mm, or 1.2 mm.

[0079] Example Group 3

[0080] Based on embodiment group 1, in some embodiments, such as Figure 1 and Figure 8 As shown, the outer shell layer 22 and the frame 10 are integrally formed into the shell body (not shown in the figure). The frame 10 has an opening (not shown in the figure). The protective shell also includes a flexible connecting part 121 and a first button part 30. The first button part 30 is integrally set with the frame 10 through the flexible connecting part 121 and is located at the opening. Along the thickness direction of the protective shell (not shown in the figure), the projection of the first button part 30 is located inside the opening. When the protective shell is assembled with the electronic device, the first button part 30 is set to correspond with the function key of the electronic device.

[0081] The opening communicates with the receiving cavity 14. The first button portion 30 is used to abut against or be adjacent to the function key of the electronic device installed in the protective shell, so that the function key of the electronic device can be triggered when a human touches the first button portion 30.

[0082] In this application, the thickness direction of the protective shell refers to the thickness direction of the wall portion with the opening, which can be parallel to the pressing direction of the user's button operation.

[0083] The flexible connecting portion 121 is capable of displacement relative to the frame 10 when subjected to force. Therefore, when the first button portion 30 is subjected to force, it will undergo relative displacement with the frame 10 through the flexible connecting portion 121. The projection of the first button portion 30 along the thickness direction of the frame 10 is located within the opening. Therefore, the user can operate the electronic device inside the protective case by pressing the first button portion 30, causing it to displace along the thickness direction of the frame 10.

[0084] There are several ways to achieve a one-piece bonding, such as through heating or pressurizing; or by bonding the material layers together with adhesive or similar materials and then curing them. The one-piece bonding mentioned here results in at least two material layers forming an inseparable whole under non-violent intervention. This inseparable whole is also called a "one-piece integral unit".

[0085] On the one hand, the first button portion 30 located at the opening of the frame 10 is connected to the frame 10 via the flexible connecting portion 121, which improves the movement capability of the first button portion 30 relative to the frame 10. This gives the protective shell a local flexible area, improving the tactile feel of the first button portion 30 and reducing the impact of the frame 10 on the operation of the first button portion 30, thereby improving the accuracy of operating the electronic device. On the other hand, by setting the first button portion 30 at the opening of the frame 10 and connecting the first button portion 30 to the frame 10 via the flexible connecting portion 121, the sealing of the opening is increased by the first button portion 30 and the flexible connecting portion 121, thereby improving the problem of the corresponding button of the electronic device being exposed and not effectively protected. Furthermore, the shell body, the flexible connecting portion 121, and the first button portion 30 are integrally set, which improves the structural stability of the protective shell and improves the problem of insufficient connection strength and easy detachment caused by separate assembly, thereby further improving the protection capability of the electronic device.

[0086] In some embodiments, the stiffness of the shell body is greater than the stiffness of the flexible connection 121. Stiffness refers to the magnitude of the force required for a structure to produce a unit deformation when an external force is applied, and it can reflect the flexibility of a material; in most cases, the greater the stiffness of a material, the smaller its deformation capacity and the smaller its flexibility.

[0087] The stiffness of the shell body refers to the force required to produce a unit deformation when an external force is applied to the shell body, and the stiffness of the flexible connection 121 refers to the force required to produce a unit deformation when an external force is applied to the flexible connection 121. When the same force is applied to the shell body and the flexible connection 121, the deformation of the shell body is less than that of the flexible connection 121.

[0088] The rigidity of the shell body is greater than that of the flexible connecting part 121, which makes it easier to press and rebound the first button part 30, making the feedback of the first button part 30 clearer and its tactile feel more comfortable; and the flexible connecting part 121 is easily deformed under external force, which can reduce the difficulty of disassembling and assembling the protective shell; furthermore, as the main body of the protective shell, the shell body can effectively protect the entire electronic device.

[0089] In some embodiments, such as Figure 10 As shown, along the thickness direction z1 of the frame 10, the projection of the flexible connecting part 121 covers the projection and opening of the first button part 30, which facilitates the connection between the flexible connecting part 121 and the frame 10, and the connection between the flexible connecting part 121 and the first button part 30. This improves the connection stability between the flexible connecting part 121 and the first button part 30. At the same time, the covering design of the flexible connecting part 121 can effectively reduce the interference of external factors such as dust on the first button part 30, improve the reliability of the first button part 30, and improve the protective effect of the protective shell on the electronic device.

[0090] In some embodiments, such as Figure 10As shown, the shell body includes a first support layer 1111 and a second support layer 1121. The first support layer 1111 has a first opening 1011. The second support layer 1121 is stacked with at least a portion of the first support layer 1111 along the thickness direction z1 of the shell body 101, and the second support layer 1121 has a second opening 1012. Along the thickness direction z1, the first opening 1011 and the second opening 1012 at least partially overlap to form an opening. At least a portion of the flexible connection portion 121 is stacked between the first support layer 1111 and the second support layer 1121. The stiffness of both the first support layer 1111 and the second support layer 1121 is greater than the stiffness of the flexible connection portion 121. Thus, the local resistance of the first support layer 1111 and the second support layer 1121 to the intrusion of external objects is greater than that of the flexible connection 121. The first support layer 1111 and the second support layer 1121 together form the shell body of the protective shell. The first support layer 1111 and the second support layer 1121 can be the outer and inner layer materials forming the shell body. The first support layer 1111 and the second support layer 1121 can be materials with high rigidity, or they can be rigid thermosetting resin materials. The first support layer 1111 and the second support layer 1121 can also be materials with a certain degree of elasticity, such as silicone or TPU. In a specific embodiment, the first support layer 1111 and the second support layer 1121 can be made of aramid fiber material, which is woven from aramid fibers. The aramid fiber material is impregnated with epoxy resin to give it high rigidity and hardness. The first support layer 1111 and the second support layer 1121 can be formed into the shell body by hot pressing.

[0091] In some embodiments, the elasticity of the first support layer 1111 and the second support layer 1121 is less than that of the flexible connection portion 121, which makes the flexible connection portion 121 easy to deform and recover from deformation, thereby enabling operation of the electronic device inside the protective shell, while the rigid layer is not easy to deform, thus improving the protection effect on the electronic device.

[0092] The flexible connection 121 is at least partially stacked between the first support layer 1111 and the second support layer 1121. The flexible connection 121 can be fixed by the first support layer 1111 and the second support layer 1121, and a tight connection between the flexible connection 121 and the first support layer 1111 and the second support layer 1121 can be achieved. This improves the connection reliability between the flexible connection 121 and the shell body 101, and improves the positional stability and deformation controllability of the flexible connection 121 under stress.

[0093] Furthermore, the flexible connection portion 121 can be a TPU film layer, which can reduce the thickness of the flexible connection portion 121, increase the deformation space of elastic deformation, and thus increase the displacement distance of the first button portion 30 when it is pressed, thereby improving the rebound force.

[0094] In some embodiments, a gap exists between the first button portion 30 and the inner wall of the opening. The first button portion 30 can maintain a certain gap with the inner wall of the opening through the flexible connecting portion 121, ensuring the flexibility of button operation, reducing the risk of button jamming, and reducing friction between the first button portion 30 and the housing body when the user performs button operation.

[0095] In some embodiments, the inner wall of the first button portion 30, the inner wall of the opening, and the portion of the flexible connection portion 121 located in the gap form a groove (not shown); the groove provides space for the deformation of the flexible connection portion 121.

[0096] In some embodiments, the thickness of the flexible connection portion 121 at the gap is less than the thickness of the first button portion 30, which can further improve the flexibility of the flexible connection portion 121 in elastic deformation, and thus improve the displacement flexibility of the first button portion 30.

[0097] In some embodiments, the thickness of the flexible connection portion 121 is 0.1 mm to 0.5 mm. For example, the thickness is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm or 0.5 mm, etc., to further improve the elastic deformation capability of the flexible connection portion 121 and reduce the interference of the flexible connection portion 121 on user operation.

[0098] In some embodiments, the protective case is configured to protect an electronic device. The electronic device is provided with function keys. When the electronic device is assembled with the protective case, the projection of the first button portion 30 along the thickness direction z1 of the case body toward the electronic device covers one or more (two or more) of the multiple function keys on the electronic device, so that the first button portion 30 is configured to correspond to some of the function keys.

[0099] In some embodiments, the function key includes a touch-sensitive button. Specifically, the touch-sensitive button may be a touch-sensitive button, allowing a human body to control or access corresponding functions of the electronic device by touching it, such as a camera function, Near Field Communication (NFC) function, etc.

[0100] Among them, the sensing button can include capacitive sensing button or resistive sensing button, etc.

[0101] In some embodiments, the sensing button includes a capacitive sensing button. The deformability of the flexible connection portion 121 and the displaceability of the first button portion 30 can be utilized to transmit external pressing operations to the capacitive sensing button, thereby achieving a first function operation of the electronic device. Even if the first button portion 30 is an insulator, a capacitive coupling effect still exists between a conductive body such as a user and the capacitive sensing button. Therefore, when the conductive body such as a user moves relative to the first button portion 30, one or both of the coupling capacitance value and coupling position of the capacitive sensing button will change. This allows the electronic device to easily recognize the user's or other conductive body's operation of the capacitive sensing button, thereby enabling a second function operation of the electronic device. The aforementioned first function and second function can be two different functions of the electronic device, or different operations of the same function of the electronic device.

[0102] In some embodiments, the electronic device includes a mobile phone, the sensor button includes a shutter button, the protective case has a sidewall for surrounding the side of the mobile phone, a first button portion 30 is disposed on the frame 10, and the shutter button is located inside the first button portion 30. The shutter button is electrically connected to the main control of the electronic device, such as a microprocessor unit. The shutter button can convert user actions such as pressing or touching the shutter button into electrical signals and transmit them to the microprocessor unit, so that the microprocessor unit controls the camera component and other related functional components of the electronic device to work, thereby realizing at least one of the functions such as opening and closing the camera, adjusting the focus, taking a picture, and recording video.

[0103] In some embodiments, the thickness of the first button portion 30 is 0.1mm to 1.2mm. Where the thickness of the first button portion 30 is less than or equal to 1.2mm, on the one hand, the opening space of the protective shell is limited; the thinner the thickness of the first button portion 30, the more space is available for its displacement, which is beneficial for effectively transmitting the pressing operation through the first button portion 30. A thinner thickness of the first button portion 30 also reduces the overall resistance of the first button portion 30, reducing the operating distance between the user and the electronic device, thus reducing interference from the first button portion 30 of the protective shell on the user's operation of the electronic device and improving the sensitivity and reliability of the user's control of the electronic device. On the other hand, a thickness of the first button portion 30 greater than or equal to 0.1mm improves the protection capability of the function keys and also increases the service life of the first button portion 30, reducing the risk of breakage during operation.

[0104] In some embodiments, the specific thickness of the first button portion 30 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, etc.

[0105] In some embodiments, such as Figure 11 As shown, the first button part 30 includes a button body 1311 and an elastic body 1321 surrounding the button body 1311; wherein, the elasticity of the button body 1311 is greater than the elasticity of the elastic body 1321, so as to increase the rebound force on the button body 1311 through the elastic body 1321, making the pressing rebound feedback of the first button part 30 clearer.

[0106] The elastomer 1321 can work together with the flexible connector 12 to realize the press-and-rebound function of the first button part 30. In a specific embodiment, the flexible connector 12 connects the first button part 30 and the protective shell; the elastomer 1321 is connected to the flexible connector 121; furthermore, the elastomer 1321 can be tightly connected to the flexible connector 121 through a hot pressing process.

[0107] In some embodiments, the button body 1311 includes a third flexible layer (not shown), a fiber layer (not shown), and a fourth flexible layer (not shown) stacked sequentially along the thickness direction z. This stacked structure can improve the structural strength of the button body, achieve shaping of the fiber layer, prevent deformation of the fiber layer, and prevent the fiber bundles woven to form the fiber layer from loosening and spreading out.

[0108] Elastomer 1321 includes a TPU elastic ring, the third and fourth flexible layers are both TPU films, and the fiber layer is aramid fiber.

[0109] TPU elastic rings possess excellent wear resistance and tear resistance, maintaining good elasticity and stability over long-term use. Available in transparent or dark black, TPU rings are not only aesthetically pleasing but also match the colors of various electronic device casings, enhancing the overall visual appeal. The high resilience of TPU elastic rings effectively cushions button pressure, extending their lifespan. TPU elastic rings are adaptable to various environments and are not prone to aging. Furthermore, the lightweight nature of TPU material reduces the burden on devices, improving portability.

[0110] Understandably, elastomer 1321 can also be formed from other types of highly elastic polymeric materials in the prior art, such as silicone or rubber.

[0111] The third and fourth flexible layers are both TPU films. TPU films possess excellent properties such as good transparency, good formability, high melting point, and good adhesion to other film layers. This reduces the difficulty of the molding process, improves reliability and aesthetics, and enhances the visibility and texture of the fiber layers. Aramid fibers, with their high strength, high modulus, high temperature resistance, and corrosion resistance, effectively improve the structural strength and durability of the 1311 button body, ensuring stable performance even under frequent pressing. Their lightweight and soft characteristics further optimize the button's tactile feel and rebound, enhancing the user experience.

[0112] The fiber layer includes, but is not limited to, aramid fibers, such as dry aramid fibers or aramid fibers impregnated with thermoplastic resin, or other types of fiber materials known in the prior art.

[0113] In some embodiments, the fiber layer comprises a composite layer of aramid fibers and TPU. The aramid fibers, pre-impregnated with a thermoplastic resin (e.g., polyurethane), are used as the fiber layer after molding, or a laminate of aramid fibers and TPU is used as the fiber layer.

[0114] The fiber layer can also be pre-impregnated with epoxy resin. Pre-impregnated aramid fiber layers reduce the material's flexibility and improve its stiffness, wear resistance, impact resistance, and other physical properties. Alternatively, the fiber layer can be left unimpregnated with epoxy resin to maintain its softness. All of the above treatments fall within the scope of this application.

[0115] In some embodiments, the first button portion 30 includes a conductive layer (not shown), the outer surface of which is covered by a flexible connection portion 121, and the conductive layer is located at least at the opening. The conductive layer is a layered conductive structure, which can be a single-layer structure or a multi-layer composite structure, and is mainly used to provide electrical conductivity to form a coupling capacitance between the user's finger and the sensing button 211.

[0116] In some embodiments, the first button portion 30 further includes a first body layer (not shown), which is disposed on the outside of the conductive layer, and the outer side of the first body layer is covered by the flexible connection portion 121.

[0117] The first body layer can be made of wear-resistant materials such as aramid fiber or aramid fiber impregnated with thermoplastic resin.

[0118] In some embodiments, the conductive layer includes a conductive film layer. This conductive film layer refers to a thin film of conductive material with a relatively thin thickness. This reduces the physical barrier between the user's finger and the sensor button of the electronic device, making the feedback more intuitive and the tactile sensation more sensitive when the user presses or slides the first button portion 30. Secondly, the conductive film layer has a flexible property similar to a thin film, allowing it to more closely conform to the deformation of the flexible connection portion when the user slides or presses, avoiding a stiff feel or delayed feedback due to excessive rigidity.

[0119] In some embodiments, the conductive film layer is a TPU conductive film layer.

[0120] In some embodiments, the conductive layer may include a circuit board, wherein the circuit board may include a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit).

[0121] The advantage of the circuit board lies in its ability to accurately identify the touch position of a user or other conductive object on the first button 30 through its structural design, thereby further improving touch accuracy. For example, in one application scenario, the circuit board, by designing a capacitor array or capacitive sensing area, can accurately identify the touch position by sensing changes in the electric field when the user touches it, and further improve touch accuracy by capacitively sensing the function keys of the electronic device through the circuit board.

[0122] In some embodiments, the conductive layer includes a plurality of conductive regions insulated along a first direction; wherein the first direction is the length direction of the first button portion. A user can slide or tap the first button portion 30 along its length. A specific insulating layout design can precisely improve the conductive layer's ability to capture and recognize the specific touch positions of conductive objects such as users, thereby improving the control accuracy when the user controls the sensor button of the electronic device via the first button portion 30.

[0123] The first button section 30 has segmented conductive areas. After the electronic device is mounted on the protective shell, the first button section 30 approaches or contacts the sensing button. When the user touches the first button section 30 with a conductive body, the conductive areas will form coupling capacitors between themselves and the conductive body (human body) and between themselves and the sensing button. These two coupling capacitors can be considered to be connected in series, thus forming a series capacitor between the conductive body and the sensing button. During the movement of the conductive body along the first direction x, it will sequentially form series capacitors with the multiple segmented conductive areas. In actual use, when the user slides their finger, the finger (or conductive body) forms a series capacitor with the corresponding conductive area. The chip accurately identifies and positions the finger by sensing the capacitance change at the corresponding position.

[0124] To further improve the user experience when triggering the sensor button of the electronic device through the first button portion 30, the first button portion 30 can be further improved. The inner surface of the first button portion 30 is flush with or protrudes inward relative to the inner surface of the outer peripheral area of ​​the opening to form a first protrusion. The design of the first protrusion can reduce the operation process when the user presses the button, improve the trigger sensitivity, and optimize the user experience.

[0125] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
