Description

Technical Field

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

[0002] To improve the protection of electronic devices and save space, protective cases can be made of rigid yet thin materials. These cases typically require openings in certain locations to accommodate the needs of electronic devices. However, because the cases are thin and rigid, users may experience a cutting sensation when their hands come into contact with the edges of the openings, posing a risk of scratches and negatively impacting the user experience. Utility Model Content

[0003] In view of the above problems, this application provides a protective case to improve the problem of the opening edge scratching the hand by providing a flexible part at the opening of the protective case body, thereby improving the user experience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is conceived as follows: This application provides a protective shell, the protective shell comprising: a shell body having a first opening; a flexible portion located within at least a portion of the inner wall of the first opening and extending from the inner wall into the opening region of the first opening, forming a second opening, the second opening penetrating the shell body along the thickness direction of the shell body; wherein the stiffness of the flexible portion is less than the stiffness of the shell body.

[0005] The beneficial effects of the embodiments of this application, which differ from the prior art, are as follows: The protective shell proposed in this application includes a shell body with a first opening and a flexible part located within at least a portion of the inner wall of the first opening. The flexible part extends from the inner wall into the opening area of ​​the first opening and forms a second opening, which penetrates the shell body along its thickness direction. The stiffness of the flexible part is less than that of the shell body. The greater stiffness of the shell body improves the structural strength of the protective shell, thereby enhancing the protection of electronic devices. The lower stiffness of the flexible part alleviates the problem of the edge of the first opening being scratchy, making it more comfortable to touch. Furthermore, the flexible part extends from the inner wall of the first opening towards the opening area of ​​the first opening to form a second opening, which penetrates the shell body along its thickness direction, thus realizing the function of the original opening (adapting to the usage needs of electronic devices). In this way, this application can improve the problem of the opening edge of the protective shell being scratchy, enhancing the user experience. Moreover, the flexible part reduces the area of ​​the opening on the protective shell, improving the overall integrity and aesthetics of the protective shell. Attached Figure Description

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0010] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0011] The protective case provided in this application is applicable to a variety of electronic devices. These electronic devices can operate independently of the case and / or in conjunction with it. For example, the protective case can be used on mobile phones, tablets, portable media players, cameras, and other portable electronic devices, providing enhanced protection. Embodiments in this application will be described using a mobile phone as an example, and the protective case will also be described using a mobile phone protective case as an example.

[0012] Example Group 1: This application proposes a protective shell, such as Figures 1 to 4As shown, Figure 1 This is a schematic diagram of the structure of the first embodiment of the protective shell of this application; Figure 2 yes Figure 1 A schematic diagram of the disassembly structure of the protective casing; Figure 3 yes Figure 1 A schematic diagram of the protective shell from one side; Figure 4 yes Figure 3 A schematic diagram of a protective case housing an electronic device. The protective case 100 includes: a case body 10 and a flexible portion 20. The case body 10 has a first opening 11. The flexible portion 20 is located within at least a portion of the inner wall of the first opening 11 and extends from the inner wall into the opening area of ​​the first opening 11, forming a second opening 21. The second opening 21 penetrates the case body 10 along its thickness direction. The stiffness of the flexible portion 20 is less than the stiffness of the case body 10.

[0013] The flexible part 20 extending from the inner wall into the opening area of ​​the first opening 11 means that the flexible part 20 is connected to the inner wall and covers part of the opening area of ​​the first opening 11.

[0014] The thickness direction of the shell body 10 refers to the thickness direction of the wall portion with the first opening 11.

[0015] Stiffness refers to the force required to produce a unit deformation when an external force is applied to a structure, 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.

[0016] The stiffness of the shell body 10 refers to the force required to produce a unit deformation when an external force is applied to the shell body 10, and the stiffness of the flexible part 20 refers to the force required to produce a unit deformation when an external force is applied to the flexible part 20. When the same force is applied to the shell body 10 and the flexible part 20, the deformation of the shell body 10 is less than the deformation of the flexible part 20.

[0017] The rigidity of the shell body 10 is greater than that of the flexible part 20, which improves the structural strength of the protective shell 100 and thus enhances the protection of the electronic device 200. The flexible part 20 has lower rigidity, which alleviates the problem of the edge of the first opening 11 being rough to the touch, making it more comfortable to the touch. Furthermore, the flexible part 20 extends from the inner wall of the first opening 11 into the opening area of ​​the first opening 11, forming a second opening 21. The second opening 21 penetrates the shell body 10 along its thickness direction to achieve the function of the original opening (adapting to the usage requirements of the electronic device). In this way, this application can improve the problem of the edge of the opening of the protective shell 100 being rough to the touch, enhancing the user experience. Moreover, the flexible part 20 reduces the area of ​​the opening on the protective shell 100, which can improve the overall integrity and aesthetics of the protective shell 100.

[0018] In some embodiments, the first opening 11 and the second opening 21 can be a notch or a through hole. The flexible part 20 can be disposed only on one side of the inner wall of the first opening 11, or it can be disposed around multiple inner walls of the first opening 11.

[0019] In some embodiments, at least one first opening 11 is provided on the shell body 10, and a flexible portion 20 is provided at at least one first opening 11.

[0020] In some embodiments, such as Figure 1 The shell body 10 and the flexible part 20 are integrated to improve the structural stability of the protective shell 100, improve the problem of insufficient connection strength and easy detachment caused by separate assembly, further improve the protection capability of electronic equipment 200, and facilitate use.

[0021] There are several ways to achieve a one-piece design. For example, heating or pressurizing can melt the relevant substances in at least two material layers, allowing them to flow to a specific location under pressure or a mold, and then solidify under the influence of temperature or pressure. Alternatively, the material layers can be bonded together with adhesive or similar materials and then cured. This one-piece design results in at least two material layers forming an inseparable whole without violent intervention; this inseparable whole is also known as a "one-piece integral design."

[0022] In some embodiments, the shell body 10 and the flexible part 20 are integrally hot-pressed. This ensures the connection strength between the shell body 10 and the flexible part 20 while simplifying the manufacturing process and improving production efficiency.

[0023] In some embodiments, the shell body 10 and the flexible part 20 can be two-color injection molded. For example, when the shell body 10 and the flexible part 20 are made of different types of thermoplastic resins, the shell body 10 and the flexible part 20 can be two-color injection molded. This can reduce labor and logistics costs and avoid tolerance accumulation caused by separate assembly.

[0024] In some embodiments, such as Figure 5 As shown, the flexible portion 20 is recessed inward relative to the outer surface of the shell body 10. After the protective shell 100 is formed, the outer surface of the flexible portion 20 facing away from the receiving cavity 14 is recessed inward relative to the outer surface of the shell body 10 towards the receiving cavity 14 along the thickness direction of the shell body 10, so that the flexible portion 20 does not protrude outward from the shell body 10, increasing the aesthetics of the protective shell 100 and reducing interference with the hands, etc. The recess depth can be 0.1 mm, 0.2 mm, or 0.3 mm, etc.

[0025] In some embodiments, such as Figures 8 to 11 As shown, the shell body 10 includes a first support layer 12 and a second support layer 13.

[0026] In some embodiments, such as Figure 10 As shown, the edge of the flexible part 20 is disposed between the first support layer 12 and the second support layer 13. That is, the edge of the flexible part 20 is sandwiched between the first support layer 12 and the second support layer 13, so that the flexible part 20 is integrally formed with the shell body 10, which improves the structural stability of the protective shell 100, improves the problem of insufficient connection strength and easy detachment caused by separate assembly, and can further improve the protection capability of the electronic device 200, while facilitating use.

[0027] In some embodiments, the inner side of the flexible portion 20 is smoothly disposed with respect to the side of the first support layer 12 opposite to the second support layer 13, and the outer side of the flexible portion 20 is flush with the side of the second support layer 13 opposite to the first support layer 12. The inner side of the flexible portion 20 refers to the side of the flexible portion 20 facing the first support layer 12, which is smoothly disposed with respect to the side of the first support layer 12 opposite to the second support layer 13, making the edge of the first opening 11 smoother and improving the problem of the edge of the first opening 11 being rough to the hand. The outer side of the flexible portion 20 is the side opposite to its inner side, which is flush with the side of the second support layer 13 opposite to the first support layer 12, making the connection between the first opening 11 and this side flush, further enhancing the structural stability of the protective shell 100 and improving the aesthetics of the protective shell 100.

[0028] In some embodiments, such as Figure 10 The shell body 10 includes a first support layer 12 and a second support layer 13 stacked along the thickness direction D. The first support layer 12 is provided with a first sub-opening 111, and the second support layer 13 is provided with a second sub-opening 112. The first sub-opening 111 and the second sub-opening 112 are connected to form the first opening 11 to meet the usage requirements of the electronic device 200.

[0029] In some embodiments, such as Figure 11 , Figure 11 This is a schematic diagram of the layered structure of a portion of the protective shell in the fourth embodiment of this application. The flexible part 20 is partially disposed within the first sub-opening 111 and partially disposed within the second sub-opening 112; the inner diameter of the first sub-opening 111 is smaller than the inner diameter of the second sub-opening 112, so as to form a boss within the first opening 11.

[0030] In this embodiment, the inner diameter of the first sub-opening 111 is smaller than the inner diameter of the second sub-opening 112, so that when the flexible part 20 is partially disposed in the first sub-opening 111 and partially disposed in the second sub-opening 112, the contact area between the flexible part 20 and the shell body 10 is increased, the firmness of the flexible part 20 and the shell body 10 being integrally disposed is improved, and the structural stability of the protective shell 100 is improved.

[0031] The second support layer 13 is positioned closer to the receiving cavity 14 than the first support layer 12, meaning the first support layer 12 is located outside the second support layer 13, which can improve the problem of the flexible part 20 falling out of the first opening 11.

[0032] In some embodiments, the flexible portion 20 includes an annular flexible portion 22 surrounding the outer periphery of the second opening 21. The annular flexible portion 22 surrounds the inner periphery of the first opening 11 and the outer periphery of the second opening 21 to enhance the aesthetics of the protective shell 100, and by completely covering the inner periphery of the first opening 11, it can further improve the problem of the first opening 11 scratching the hand.

[0033] In some embodiments, such as Figures 1 to 4 As shown, the second opening 21 is a semi-closed notch to increase the flexibility of the second opening 21 and facilitate operation of electronic devices or connectors.

[0034] In some embodiments, such as Figures 1 to 4 As shown, the first opening 11 is a semi-closed notch, and the flexible part 20 is provided on the inner wall of the notch, the inner wall including the first bottom wall and / or the first side wall.

[0035] In some embodiments, the flexible portion 20 is disposed on the first bottom wall and the first side wall of the notch so that the flexible portion 20 covers the entire inner wall of the notch, thereby making it more comfortable to touch.

[0036] In some embodiments, the flexible portion 20 is disposed only on the first bottom wall of the notch or only on the first side wall of the notch to reduce costs.

[0037] In some embodiments, Figure 15 As shown, Figure 15 This is a schematic diagram of the structure of the protective shell, electronic device, and connector assembled according to this application. The shell body 10 has a receiving cavity 14 for accommodating the electronic device 200. The second opening 21 is for the connector 400 to pass through and connect to the electronic device 200 in the receiving cavity 14. The connector 400 includes a conductive head 410 and a connector base 420 disposed on the outer periphery of the conductive head 410. Along the thickness direction D of the shell body 10, the size of the second opening 21 is larger than the size of the conductive head 410 and smaller than the size of the connector base 420, so that when the connector 400 is inserted into the shell body 10, the conductive head 410 passes through the second opening 21, and the flexible part 20 is located between the connector base 420 and the shell of the electronic device 200.

[0038] The conductive head 410 is used to transmit electricity with the electronic device 200, and the plug 420 is used to support the conductive head 410 and to position the conductive head 410 when the housing body 10 is provided with the plug 400, thereby improving the problem that the insertion stroke of the conductive head 410 is too large or too small.

[0039] By providing a second opening 21 on the flexible part 20, the connection point between the conductive head 410 and the electronic device 200 is avoided, thus accommodating the wiring needs of the electronic device 200 for charging or communication. When the connector 400 is inserted into the housing body 10, the conductive head 410 passes through the second opening 21, and the flexible part 20 is located between the connector 420 and the housing of the electronic device 200. This increases the coverage area of ​​the flexible part 20, reduces the opening area of ​​the second opening 21, improves the overall integrity and appearance coordination of the protective housing 100, and alleviates the problem of scratching hands. Furthermore, the flexible part 20 does not obstruct the connection between the conductive head 410 and the electronic device 200.

[0040] In one application scenario, the connector 400 can be a Type-C charging head, etc., the conductive head 410 is the metal connector of the charging head and its internal pins, and the socket 420 is an insulating shell disposed on the outer periphery of the metal connector, with the metal connector protruding from the insulating shell. When connected to an electronic device, the end of the metal connector is inserted into the charging port of the electronic device, and the end of the insulating shell abuts against the outer shell of the electronic device.

[0041] In some embodiments, the dimension d of the flexible portion 20 along the thickness direction D is less than or equal to 1.3 mm.

[0042] The dimension d is set to 1.3 mm or less so that when the flexible part 20 is located between the connector 420 and the housing of the electronic device 200, the flexible part 20 is not too thick, which would affect the connection stability between the conductive head 410 and the electronic device 200, ensuring the normal operation of the connector 400. It also reduces the stiffness of the flexible part 20, increases its flexibility, and reduces the resistance of the flexible part 20 to the connector 400 during insertion. Simultaneously, the flexible part 20 has a certain thickness, enhancing its structural stability. This dimension d can be 1.3 mm, 1.2 mm, 1.1 mm, 1.0 mm, 0.9 mm, 0.8 mm, 0.7 mm, 0.6 mm, 0.5 mm, 0.4 mm, 0.3 mm, 0.2 mm, or 0.1 mm.

[0043] In some embodiments, the dimension d of the flexible portion 20 along the thickness direction D is less than or equal to 0.6 mm. Setting this dimension d to 0.6 mm or less further reduces the stiffness of the flexible portion 20, increases its flexibility, and further reduces the resistance of the flexible portion 20 to the connector 400 during insertion; simultaneously, the flexible portion 20 has a certain thickness, enhancing its structural stability; and it also improves the insertion and removal feel of the connector. This dimension d can be 0.6 mm, 0.58 mm, 0.56 mm, 0.54 mm, 0.52 mm, 0.5 mm, etc.

[0044] In some embodiments, the dimension d of the flexible portion 20 along the thickness direction D is 0.1 mm to 0.5 mm.

[0045] In some embodiments, the dimension d can specifically be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, etc.

[0046] The specific value of dimension d can be adjusted according to the material properties and dimensions of the shell body 10 and the flexible part 20. This dimension d is set within this range so that when the flexible part 20 is located between the connector and the shell of the electronic device 200, the flexible part 20 is not too thick, which would affect the connection stability between the conductive head 410 and the electronic device 200; it also reduces the stiffness of the flexible part 20, increases its flexibility, and reduces the resistance of the flexible part 20 to the connector 400 during the insertion process; at the same time, the flexible part 20 has a certain thickness, enhancing its structural stability.

[0047] In some embodiments, such as Figure 12 and Figure 13 As shown, Figure 12 This is a structural schematic diagram of the fifth embodiment of the protective shell of this application. Figure 13 This is a structural schematic diagram of the sixth embodiment of the protective shell of this application. The stiffness of the first region 201 of the flexible part 20 near the second opening 21 is less than the stiffness of the second region 202 near the shell body 10. On the one hand, the lower stiffness of the first region 201 of the flexible part 20 near the second opening 21 can further improve the problem of the opening edge of the protective shell 100 being scratchy; on the other hand, the higher stiffness of the second region 202 of the flexible part 20 near the shell body 10 can enhance the structural stability of the flexible part 20, thereby enhancing the overall structural stability of the protective shell 100.

[0048] The second region 202 of the flexible part 20 near the shell body 10 refers to the region where the flexible part 20 connects to the shell body 10.

[0049] In some embodiments, the size ratio of the first region 201 and the second region 202 can be adjusted according to the material properties and size parameters of the flexible part 20.

[0050] In some embodiments, such as Figure 12 and Figure 13 As shown, the thickness of the first region 201 is less than the thickness of the second region 202. The thickness of the first region 201 of the flexible part 20 near the second opening 21 is smaller, so that the stiffness of the first region 201 is smaller, which can further improve the problem of the edge of the opening of the protective shell 100 being scratchy; the thickness of the second region 202 of the flexible part 20 near the shell body 10 is larger, so that the stiffness of the second region is larger, which enhances the structural stability of the flexible part 20.

[0051] In other embodiments, the stiffness of the first region 201 can be less than that of the second region 202 by using a material with lower stiffness in the first region 201 and a material with higher stiffness in the second region 202.

[0052] In some embodiments, the flexible portion 20 may further include multiple regions with different stiffnesses, the stiffness of which gradually decreases from the shell body 10 to the second opening 21.

[0053] In some embodiments, such as Figures 1 to 4 , Figure 10 As shown, the second opening 21 is a semi-closed notch.

[0054] In some embodiments, such as Figures 1 to 4 As shown, the shell body 10 includes a second bottom wall 101 and a second side wall 102 disposed on the outer periphery of the second bottom wall 101. The first opening 11 includes a notch disposed on the second side wall 102 to accommodate the usage requirements of the electronic device 200.

[0055] In some embodiments, the first opening 11 may also be a through hole provided on the second side wall 102, or a through hole provided on the second bottom wall 101, or a through hole or notch extending from the second bottom wall 101 to the second side wall 102. The shell body 10 may also include a plurality of first openings 11, the specific shape, size, number and distribution position of which may be adjusted according to the usage requirements of the electronic device 200.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the notch extends from the second sidewall 102 to the second bottom wall 101 to increase the coverage area of ​​the flexible part 20 and further enhance the comfort of the protective shell 100.

[0057] In some embodiments, such as Figures 1 to 4 As shown, the first opening 11 is located on the lower side wall of the housing body 10, and the second opening 21 is configured to accommodate a connector 400, which includes a charging connector (not shown). The lower side wall of the housing body 10 is the portion of the side wall corresponding to the lower edge of the electronic device 200 when the electronic device 200 is in its standard usage posture. The second opening 21 is configured to accommodate the charging connector to meet the charging needs of the electronic device 200.

[0058] In some embodiments, such as Figure 11As shown, the first support layer 12 includes a first aramid fiber layer 121, the second support layer 13 includes a second aramid fiber layer 131, and the flexible part 20 includes a thermoplastic polyurethane (TPU) layer 23. The aramid fiber layer is woven from aramid fibers and impregnated with epoxy resin to give it high rigidity and hardness. The first support layer 12 and the second support layer 13 can be formed into the shell body 10 by hot pressing. Aramid fibers have high strength, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of the shell body 10; TPU has excellent properties such as good transparency, good formability, high melting point, and good adhesion to other layers, which can reduce the difficulty of molding process and improve reliability and aesthetics.

[0059] In other embodiments, the first support layer 12 and the second support layer 13 may also be made of high elastic modulus materials such as polycarbonate (PC); the flexible part 20 may also be made of low elastic modulus materials such as rubber and silicone.

[0060] In some embodiments, the first support layer 12 and the second support layer 13 can be formed into the shell body 10 by a hot pressing process. In the hot pressing process, the edge of the flexible part 20 is hot-pressed between the first support layer 12 and the second support layer 13 so as to be integrally formed with the shell body 10.

[0061] In some embodiments, the flexible portion 20 includes a flexible fluorescent portion (not shown) to make the flexible portion 20 stand out in a dark environment, thereby improving the problem that users cannot locate the second opening 21 in a dark environment.

[0062] In some embodiments, such as Figure 14 As shown, the shell body 10 has a second sidewall 102 and a second bottom wall 101. The second sidewall 102 is disposed on the outer periphery of the second bottom wall 101 to form a receiving cavity 14. The second sidewall 102 includes a continuous annular sidewall 381, which is disposed around the side of the second bottom wall 101 near the receiving cavity 14.

[0063] The second bottom wall 101 and the annular side wall 381 form a side-enclosed structure, which can improve the protection capability of electronic equipment. In other words, the continuous annular side wall 381 refers to a section of the side wall that is not completely broken; it can be understood that there are gaps or through holes on the side wall, but no completely broken section is formed, which also falls within the protection scope of the continuous side wall.

[0064] Example Group 2: In some embodiments, such as Figures 5 to 8 , Figure 15As shown, the protective shell 100 includes: a shell body 10, forming a receiving cavity 14 and a second opening 21 communicating with the receiving cavity 14, the receiving cavity 14 being used to accommodate an electronic device 200; wherein, the second opening 21 is configured to allow a connector 400 to pass through, the connector 400 including a conductive head 410 and a connector base 420 disposed on the outer periphery of the conductive head 410; along the thickness direction D of the shell body 10, the size of the second opening 21 is larger than the size of the conductive head 410 and smaller than the size of the connector base 420, so that when the connector 400 is inserted into the shell body 10, the conductive head 410 passes through the second opening 21, and the outer peripheral region A of the second opening 21 is located between the connector base 420 and the shell of the electronic device 200; wherein, the size of the outer peripheral region A along the thickness direction D is less than or equal to 1.3 mm.

[0065] The conductive head 410 is used to transmit electricity with the electronic device 200, and the plug 420 is used to support the conductive head 410 and to position the conductive head 410 when the housing body 10 is provided with the plug 400, thereby improving the problem that the insertion stroke of the conductive head 410 is too large or too small.

[0066] The second opening 21 avoids the connection point between the conductive head 410 and the electronic device 200, accommodating the wiring needs of the electronic device 200 for charging or communication. When the connector 400 is inserted into the housing body 10, the conductive head 410 passes through the second opening 21. The outer periphery of the second opening 21 is located between the connector 420 and the housing of the electronic device 200, which can increase the coverage area of ​​the outer periphery A, reduce the opening area of ​​the second opening 21, improve the overall integrity and appearance coordination of the protective housing 100, and improve the problem of scratching hands. Furthermore, the dimension d of the outer periphery A of the second opening 21 along the thickness direction D is set to 1.3mm or less, so that when the outer periphery A is located between the connector 420 and the housing of the electronic device 200, the outer periphery A will not be too thick and affect the connection stability between the conductive head 410 and the electronic device 200, allowing the connector 400 to work normally. At the same time, the outer periphery A has a certain thickness, which enhances the structural stability of the flexible part 20.

[0067] In one application scenario, the connector 400 can be a Type-C charging head, etc., the conductive head 410 is the metal connector of the charging head and its internal pins, and the socket 420 is an insulating shell disposed on the outer periphery of the metal connector, with the metal connector protruding from the insulating shell. When connected to an electronic device, the end of the metal connector is inserted into the charging port of the electronic device, and the end of the insulating shell abuts against the outer shell of the electronic device.

[0068] Among them, the outer peripheral region A of the second opening 21 refers to the area on the protective shell 100 that forms the second opening 21, that is, the side wall region of the second opening 21.

[0069] In some embodiments, the housing body 10 has a second sidewall 102 and a second bottom wall 101. The second sidewall 102 is disposed on the outer periphery of the second bottom wall 101. The second sidewall 102 and the second bottom wall 101 enclose each other to form a receiving cavity 14. The receiving cavity 14 is configured to accommodate at least a portion of the electronic device 200. When the first opening 11 is provided on the second sidewall 102, the thickness direction D refers to the thickness direction D of the second sidewall 102 of the housing body 10, and the thickness direction D is perpendicular to the second sidewall 102. When the first opening 11 is provided on the second bottom wall 101, the thickness direction D refers to the thickness direction of the second bottom wall 101, and the thickness direction D is perpendicular to the second bottom wall 101. In other embodiments, the housing body 10 may include a top wall. The top wall, the second bottom wall 101, and the second sidewall 102 enclose each other to form a fully enclosed receiving cavity 14 to completely enclose the electronic device 200.

[0070] The dimension d can be 1.3mm, 1.2mm, 1.1mm, 1.0mm, 0.9mm, 0.8mm, 0.7mm, 0.6mm, 0.5mm, 0.4mm, 0.3mm, 0.2mm, or 0.1mm.

[0071] In some embodiments, the dimension d of the outer peripheral region A along the thickness direction is less than or equal to 0.6 mm. Setting this dimension d to 0.6 mm or less further reduces the resistance of the outer peripheral region to the connector 400 during insertion; simultaneously, the outer peripheral region has a certain thickness, enhancing its structural stability; and improving the insertion and removal feel of the connector. This dimension d can be 0.6 mm, 0.58 mm, 0.56 mm, 0.54 mm, 0.52 mm, 0.5 mm, etc.

[0072] In some embodiments, the outer peripheral region A has a dimension of 0.1 mm to 0.5 mm along the thickness direction D. Specifically, this dimension d can be 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, etc.

[0073] The specific value of dimension d can be adjusted according to the material properties and dimensions of the shell body 10. This dimension d is set within this range so that when the outer peripheral region A is located between the plug and the shell of the electronic device 200, the outer peripheral region is not too thick and thus does not affect the connection stability between the conductive head 410 and the electronic device 200; at the same time, the outer peripheral region A has a certain thickness to enhance the structural stability of the outer peripheral region A.

[0074] In some embodiments, such as Figure 9 , Figure 9This is a schematic diagram of the layered structure of the main body of the protective shell in this application. The main body 10 includes a first support layer 12 and a second support layer 13 stacked along the thickness direction D. The first support layer 12 has a first opening 11 to form an outer peripheral region A in the overlapping area of ​​the second support layer 13 and the first opening 11. The second support layer 13 has a second opening 21, which communicates with the first opening 11.

[0075] The shell body 10 is composed of a first support layer 12 and a second support layer 13, while the outer peripheral region A is composed only of the second support layer 13. By reducing the thickness of a local area of ​​the shell body 10, that is, by reducing the thickness of the local area through the setting of the opening area of ​​the first opening 11, not only can the problem of the edge of the first opening 11 being scratchy be improved, making it more comfortable to touch, but also the outer peripheral region A is not too thick, which would affect the connection stability between the conductive head 410 and the electronic device 200.

[0076] Furthermore, in this embodiment, the outer peripheral area can be achieved simply by cutting or molding the first support layer 12, without the need to add other material components. This results in high structural stability and aesthetic appeal.

[0077] In some embodiments, the housing body 10 is formed with a receiving cavity 14 for accommodating an electronic device 200; the first support layer 12 is disposed closer to the receiving cavity 14 than the second support layer 13, that is, the first support layer 12 is located inside the second support layer 13.

[0078] The shell body 10 achieves the first opening 11 by cutting the inner material, which can increase the aesthetics of the protective shell 100 and solve the problem that the first opening 11 on the outside will scratch the hand.

[0079] In some embodiments, the shell body 10 further includes an inner liner (not shown) disposed within the first opening 11 and covering the inner side of the second support layer 13. The inner liner can improve problems such as the first support layer 12 being prone to loosening and deformation at the first opening 11.

[0080] In some embodiments, the first support layer 12 includes a first aramid fiber layer, and the second support layer 13 includes a second aramid fiber layer. The inner liner may be a TPU layer, etc.

[0081] In some embodiments, the second opening 21 may be a notch or a through hole; it may be provided on the second sidewall 102 and / or the second bottom wall 101.

[0082] In some embodiments, such as Figures 1 to 4As shown, the shell body 10 is provided with a first opening 11, and the protective shell 100 further includes a flexible part 20, which is located in at least a portion of the inner wall of the first opening 11 and extends from the inner wall to the opening area of ​​the first opening 11, and forms a second opening 21, so that the flexible part 20 is the outer peripheral area of ​​the second opening 21; wherein, the stiffness of the flexible part 20 is less than the stiffness of the shell body 10.

[0083] The flexible part 20 extending from the inner wall into the opening area of ​​the first opening 11 means that the flexible part 20 is connected to the inner wall and covers part of the opening area of ​​the first opening 11.

[0084] The thickness direction of the shell body 10 refers to the thickness direction of the wall portion with the first opening 11.

[0085] Stiffness refers to the force required to produce a unit deformation when an external force is applied to a structure, 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.

[0086] The stiffness of the shell body 10 refers to the force required to produce a unit deformation when an external force is applied to the shell body 10, and the stiffness of the flexible part 20 refers to the force required to produce a unit deformation when an external force is applied to the flexible part 20. When the same force is applied to the shell body 10 and the flexible part 20, the deformation of the shell body 10 is less than the deformation of the flexible part 20.

[0087] The rigidity of the shell body 10 is greater than that of the flexible part 20, which improves the structural strength of the protective shell 100 and thus enhances the protection of the electronic device 200. The flexible part 20 has lower rigidity, which alleviates the problem of the edge of the first opening 11 being rough to the touch, making it more comfortable to the touch. Furthermore, the flexible part 20 extends from the inner wall of the first opening 11 into the opening area of ​​the first opening 11, forming a second opening 21. The second opening 21 penetrates the shell body 10 along its thickness direction to achieve the function of the original opening (adapting to the usage requirements of the electronic device). In this way, this application can improve the problem of the edge of the opening of the protective shell 100 being rough to the touch, enhancing the user experience. Moreover, the flexible part 20 reduces the area of ​​the opening on the protective shell 100, which can improve the overall integrity and aesthetics of the protective shell 100.

[0088] In some embodiments, the first opening 11 and the second opening 21 can be a notch or a through hole. The flexible part 20 can be disposed only on one side of the inner wall of the first opening 11, or it can be disposed around multiple inner walls of the first opening 11.

[0089] In some embodiments, such as Figure 1The shell body 10 and the flexible part 20 are integrated to improve the structural stability of the protective shell 100, improve the problem of insufficient connection strength and easy detachment caused by separate assembly, further improve the protection capability of electronic equipment 200, and facilitate use.

[0090] There are several ways to achieve a one-piece design. For example, heating or pressurizing can melt the relevant substances in at least two material layers, allowing them to flow to a specific location under pressure or a mold, and then solidify under the influence of temperature or pressure. Alternatively, the material layers can be bonded together with adhesive or similar materials and then cured. This one-piece design results in at least two material layers forming an inseparable whole without violent intervention; this inseparable whole is also known as a "one-piece integral design."

[0091] In some embodiments, the shell body 10 and the flexible part 20 are integrally hot-pressed. This ensures the connection strength between the shell body 10 and the flexible part 20 while simplifying the manufacturing process and improving production efficiency.

[0092] In some embodiments, the shell body 10 and the flexible part 20 can be two-color injection molded. For example, when the shell body 10 and the flexible part 20 are made of different types of thermoplastic resins, the shell body 10 and the flexible part 20 can be two-color injection molded. This can reduce labor and logistics costs and avoid tolerance accumulation caused by separate assembly.

[0093] In some embodiments, the outer peripheral region A is recessed inward relative to the outer surface of the shell body 10 toward the inner side of the shell body 10. After the protective shell 100 is formed, the outer surface of the outer peripheral region A facing away from the receiving cavity 14 is recessed inward relative to the outer surface of the shell body 10 toward the receiving cavity 14 along the thickness direction of the shell body 10, so that the outer peripheral region A does not protrude outward from the shell body 10, thereby increasing the aesthetics of the protective shell 100 and reducing interference with the hands, etc. The recess depth can be 0.1 mm, 0.2 mm, 0.3 mm, etc.

[0094] In some embodiments, such as Figure 10 The shell body 10 includes a first support layer 12 and a second support layer 13, with the edge of the flexible part 20 disposed between the first support layer 12 and the second support layer 13. That is, the edge of the flexible part 20 is sandwiched between the first support layer 12 and the second support layer 13, so that the flexible part 20 is integrally formed with the shell body 10. This improves the structural stability of the protective shell 100, mitigates problems such as insufficient connection strength and easy detachment caused by separate assembly, further enhances the protection capability of the electronic device 200, and facilitates use.

[0095] In some embodiments, the inner side of the flexible portion 20 is smoothly disposed with respect to the side of the first support layer 12 opposite to the second support layer 13, and the outer side of the flexible portion 20 is flush with the side of the second support layer 13 opposite to the first support layer 12. The inner side of the flexible portion 20 refers to the side of the flexible portion 20 facing the first support layer 12, which is smoothly disposed with respect to the side of the first support layer 12 opposite to the second support layer 13, making the edge of the first opening 11 smoother and improving the problem of the edge of the first opening 11 being rough to the hand. The outer side of the flexible portion 20 is the side opposite to its inner side, which is flush with the side of the second support layer 13 opposite to the first support layer 12, making the connection between the first opening 11 and this side flush, further enhancing the structural stability of the protective shell 100 and improving the aesthetics of the protective shell 100.

[0096] In some embodiments, such as Figure 10 The shell body 10 includes a first support layer 12 and a second support layer 13 stacked along the thickness direction D. The first support layer 12 is provided with a first sub-opening 111, and the second support layer 13 is provided with a second sub-opening 112. The first sub-opening 111 and the second sub-opening 112 are connected to form the first opening 11 to meet the usage requirements of the electronic device 200.

[0097] In some embodiments, such as Figure 11 The flexible part 20 is partially disposed in the first sub-opening 111 and partially disposed in the second sub-opening 112; the inner diameter of the first sub-opening 111 is smaller than the inner diameter of the second sub-opening 112, so as to form a boss in the first opening 11.

[0098] In this embodiment, the inner diameter of the first sub-opening 111 is smaller than the inner diameter of the second sub-opening 112, so that when the flexible part 20 is partially disposed in the first sub-opening 111 and partially disposed in the second sub-opening 112, the contact area between the flexible part 20 and the shell body 10 is increased, the firmness of the flexible part 20 and the shell body 10 being integrally disposed is improved, and the structural stability of the protective shell 100 is improved.

[0099] The second support layer 13 is positioned closer to the receiving cavity 14 than the first support layer 12, which can improve the problem of the flexible part 20 falling out of the first opening 11.

[0100] In some embodiments, such as Figures 5 to 8 As shown, the flexible portion 20 includes an annular flexible portion 22 surrounding the outer periphery of the second opening 21. The annular flexible portion 22 surrounds the inner periphery of the first opening 11 and the outer periphery of the second opening 21 to enhance the aesthetics of the protective shell 100, and by completely covering the inner periphery of the first opening 11, it can further improve the problem of the first opening 11 scratching the hand.

[0101] In some embodiments, such as Figures 1 to 4As shown, the second opening 21 is a semi-closed notch to increase the flexibility of the second opening 21 and facilitate operation of electronic devices or connectors.

[0102] In some embodiments, such as Figures 1 to 4 As shown, the first opening 11 is a semi-closed notch, and the flexible part 20 is provided on the inner wall of the notch, the inner wall including the first bottom wall and / or the first side wall.

[0103] In some embodiments, the flexible portion 20 is disposed on the first bottom wall and the first side wall of the notch so that the flexible portion 20 covers the entire inner wall of the notch, thereby making it more comfortable to touch.

[0104] In some embodiments, the flexible portion 20 is disposed only on the first bottom wall of the notch or only on the first side wall of the notch to reduce costs.

[0105] In some embodiments, such as Figure 12 and Figure 13 As shown, the stiffness of the first region 201 of the flexible part 20 near the second opening 21 is less than the stiffness of the second region 202 near the shell body 10. On the one hand, the lower stiffness of the first region 201 of the flexible part 20 near the second opening 21 can further improve the problem of the opening edge of the protective shell 100 being scratchy; on the other hand, the higher stiffness of the second region 202 of the flexible part 20 near the shell body 10 can enhance the structural stability of the flexible part 20, thereby enhancing the overall structural stability of the protective shell 100.

[0106] The second region 202 of the flexible part 20 near the shell body 10 refers to the region where the flexible part 20 connects to the shell body 10.

[0107] In some embodiments, the size ratio of the first region 201 and the second region 202 can be adjusted according to the material properties and size parameters of the flexible part 20.

[0108] In some embodiments, such as Figure 12 and Figure 13 As shown, the thickness of the first region 201 is less than the thickness of the second region 202. The thickness of the first region 201 of the flexible part 20 near the second opening 21 is smaller, so that the stiffness of the first region 201 is smaller, which can further improve the problem of the edge of the opening of the protective shell 100 being scratchy; the thickness of the second region 202 of the flexible part 20 near the shell body 10 is larger, so that the stiffness of the second region is larger, which enhances the structural stability of the flexible part 20.

[0109] In other embodiments, the stiffness of the first region 201 can be less than that of the second region 202 by using a material with lower stiffness in the first region 201 and a material with higher stiffness in the second region 202.

[0110] In some embodiments, the flexible portion 20 may further include multiple regions with different stiffnesses, the stiffness of which gradually decreases from the shell body 10 to the second opening 21.

[0111] In some embodiments, such as Figures 1 to 4 , Figure 10 As shown, the second opening 21 is a semi-closed notch.

[0112] In some embodiments, such as Figures 1 to 4 As shown, the shell body 10 includes a second bottom wall 101 and a second side wall 102 disposed on the outer periphery of the second bottom wall 101. The first opening 11 includes a notch disposed on the second side wall 102 to accommodate the usage requirements of the electronic device 200.

[0113] In some embodiments, the first opening 11 may also be a through hole provided on the second side wall 102, or a through hole provided on the second bottom wall 101, or a through hole or notch extending from the second bottom wall 101 to the second side wall 102. The shell body 10 may also include a plurality of first openings 11, the specific shape, size, number and distribution position of which may be adjusted according to the usage requirements of the electronic device 200.

[0114] In some embodiments, such as Figure 1 and Figure 2 As shown, the notch extends from the second sidewall 102 to the second bottom wall 101 to increase the coverage area of ​​the flexible part 20 and further enhance the comfort of the protective shell 100.

[0115] In some embodiments, such as Figures 1 to 4 As shown, the first opening 11 is located on the lower side wall of the housing body 10, and the second opening 21 is configured to accommodate a connector 400, which includes a charging connector (not shown). The lower side wall of the housing body 10 is the portion of the side wall corresponding to the lower edge of the electronic device 200 when the electronic device 200 is in its standard usage posture. The second opening 21 is configured to accommodate the charging connector to meet the charging needs of the electronic device 200.

[0116] In some embodiments, such as Figure 11As shown, the first support layer 12 includes a first aramid fiber layer 121, the second support layer 13 includes a second aramid fiber layer 131, and the flexible part 20 includes a thermoplastic polyurethane (TPU) layer 23. The aramid fiber layer is woven from aramid fibers and impregnated with epoxy resin to give it high rigidity and hardness. The first support layer 12 and the second support layer 13 can be formed into the shell body 10 by hot pressing. Aramid fibers have high strength, high temperature resistance, and corrosion resistance, which can effectively improve the structural strength and durability of the shell body 10; TPU has excellent properties such as good transparency, good formability, high melting point, and good adhesion to other layers, which can reduce the difficulty of molding process and improve reliability and aesthetics.

[0117] In other embodiments, the first support layer 12 and the second support layer 13 may also be made of high elastic modulus materials such as polycarbonate (PC); the flexible part 20 may also be made of low elastic modulus materials such as rubber and silicone.

[0118] In some embodiments, the first support layer 12 and the second support layer 13 can be formed into the shell body 10 by a hot pressing process. In the hot pressing process, the edge of the flexible part 20 is hot-pressed between the first support layer 12 and the second support layer 13 so as to be integrally formed with the shell body 10.

[0119] In some embodiments, the flexible portion 20 includes a flexible fluorescent portion (not shown) to make the flexible portion 20 stand out in a dark environment, thereby improving the problem that users cannot locate the second opening 21 in a dark environment.

[0120] In some embodiments, such as Figure 15 As shown, the shell body 10 has a second sidewall 102 and a second bottom wall 101. The second sidewall 102 is disposed on the outer periphery of the second bottom wall 101 to form a receiving cavity 14. The second sidewall 102 includes a continuous annular sidewall 381, which is disposed around the side of the second bottom wall 101 near the receiving cavity 14.

[0121] The second bottom wall 101 and the annular side wall 381 form a side-enclosed structure, which can improve the protection capability of electronic equipment. Furthermore, a continuous side wall refers to a section of the side wall that is not completely broken; it can be understood that even if there are gaps or through holes in the side wall, but no completely broken section is formed, it is still within the protection scope of the continuous side wall.

[0122] In some embodiments, such as Figure 16As shown, the shell body 10 has a second sidewall 102; wherein, the end face of the second sidewall 102 away from the second bottom wall 101 is provided with a relief groove 2111 extending toward the second bottom wall 101 and penetrating from the inner surface of the second sidewall 102 to the outer surface; the depth of the relief groove 2111 is less than the dimension of the second sidewall 102 with the relief groove 2111 along the depth direction of the relief groove 2111.

[0123] The clearance groove 2111 can be provided on the upper sidewall of the second sidewall 102. In other embodiments, the clearance groove 2111 can also be provided at other locations on the second sidewall 102.

[0124] The receiving cavity 14 has an opening on the side facing away from the second bottom wall 101. When the opening faces the user, the side of the protective shell 100 facing away from the user is the second bottom wall 101, the side above the receiving cavity is the upper side wall, and the side below the receiving cavity is the lower side wall. After the protective shell 100 is assembled with the electronic product, when the electronic product is in the default display state, the upper side wall corresponds to the top of the electronic product, and the lower side wall corresponds to the bottom of the electronic product.

[0125] The aforementioned clearance groove refers to a slot with a accommodating space. During the use of the protective shell 100, the clearance groove can be used to accommodate other objects or accessories, such as an operator's hand or a charging port for electronic products, or it can be used to accommodate other objects.

[0126] In this embodiment, the depth of the clearance groove 2111 is less than the depth dimension of the second sidewall 102 on which the clearance groove 2111 is provided, and the clearance groove 2111 is opened from one end face of the second sidewall 102 away from the second bottom wall 101, so that the clearance groove 2111 does not penetrate the second sidewall 102 in the depth direction. On the one hand, the part of the second sidewall 102 that does not penetrate can increase the protective effect of the protective case 100 and the ability to fix the mobile phone; on the other hand, the setting of the clearance groove 2111 can improve the convenience of assembling and disassembling the protective case 100; and furthermore, the fact that the clearance groove 2111 does not penetrate the second sidewall 102 in the depth direction means that the second sidewall 102 is not interrupted, which can improve the problem of the clearance groove 2111 scratching the user's hand, thereby improving the user experience.

[0127] In some embodiments, the second sidewall 102 further includes a left sidewall and a right sidewall, and the upper sidewall, the left sidewall, the lower sidewall and the right sidewall are connected end to end to form the second sidewall 102.

[0128] In some embodiments, such as Figure 14As shown, the protective shell 100 also includes a flexible connecting portion 512 and a first button portion 513. The shell body 10 has an opening 801. The first button portion 513 is integrally formed with the shell body 10 through the flexible connecting portion 512 and is located at the opening 801. Along the thickness direction of the shell body 10, the projection of the first button portion 513 is located inside the opening 801. The shell body 10 has a side wall 113 and a bottom wall 114. The side wall 113 is located on the outer periphery of the bottom wall 114. Along the thickness direction, the projection of the flexible connecting portion 512 and / or the first button portion 513 completely covers the opening 801. The projection of the flexible connecting portion 512 and / or the first button portion 513 completely covers the opening area of ​​the opening 801 to form a full-coverage structure at the opening 801. The buttons on the electronic device are correspondingly located at the opening 801 (multiple buttons can correspond to multiple openings 801), so that the protective shell 100 can completely cover all the buttons on the electronic device.

[0129] The formation of a fully enclosed structure at the opening 801 means that the opening 801 is completely covered by the first button portion 513 and the flexible connecting portion 512, or the opening 801 is completely covered by the flexible connecting portion 512. Further, the continuous annular sidewall 381 includes the flexible connecting portion 512 and the first button portion 513 disposed on the sidewall. Further, a continuous sidewall refers to a section of the sidewall that is not completely broken; it can be understood that even if there are gaps or through holes on the sidewall, but no completely broken section is formed, it is still within the protection scope of the continuous sidewall.

[0130] Other structures of the protective shell in this embodiment can be found in the above embodiments.

[0131] The above description is merely an embodiment of this application and does not limit the patent scope of this application.
