[0037] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0038] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0039] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or indirectly on that other component.

[0040] When a component is said to be "connected to" another component, it can be directly connected to the other component or indirectly connected to that other component.

[0041] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0043] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0044] To address the problems of existing electronic device protective cases, such as the difficulty in timely heat dissipation leading to severe overheating, the need to replace the entire case if the back panel is damaged (increasing repair costs), and the inability to replace the back panel to customize the design or style, this utility model provides a protective case for electronic devices.

[0045] The following describes in detail the specific structure of a protective case for an electronic device provided by an embodiment of this utility model, according to the appendix. Figure 1-8 As shown, the specific structure of the protective case for the electronic device includes a protective case body 1, a back panel assembly 2, a steel sheet 3, and a magnet block 4.

[0046] The protective case body 1 has a receiving cavity. Specifically, the protective case body 1 is hollow and has a receiving cavity with openings on both sides, which can provide a certain degree of protection for electronic devices. At the same time, the opening on one side makes it easy to detachably assemble and install electronic devices into the receiving cavity, making it convenient for users to put electronic devices into the receiving cavity or take out electronic devices.

[0047] It should be noted that the cavity can be customized according to the specific size of the electronic device to provide enough space to accommodate various electronic devices; for example, since the design of each generation of Apple iPhone or Apple iPad is somewhat different, the cavity can be customized according to different types of Apple iPhones or Apple iPads.

[0048] according to Figure 2 and Figure 3 As shown, the rear panel assembly 2 includes a first rear panel 21 and a second rear panel 22. The first rear panel 21 is detachably disposed in the receiving cavity so that the receiving cavities are separated to form a first receiving cavity and a second receiving cavity.

[0049] Specifically, since the first back panel 21 is detachably mounted within the accommodating cavity, cleaning and maintenance of the protective case become simpler and more convenient. For example, when the end face of the first back panel 21 becomes dirty or damaged, the user can directly remove the first back panel 21 for cleaning or replacement of the entire first back panel 21. This design eliminates the need for the user to replace the entire protective case. Furthermore, the replaceable portion of the first back panel 21 may be made of protective material, such as a metal plate. Replacing the first back panel 21 with this type of material enhances the electronic device's protection against drops and scratches, without requiring the replacement of the entire protective case.

[0050] It should also be noted that when the electronic device is fitted with a protective case, the electronic device is fitted into the second cavity, and the second back panel 22 is detachably disposed in the first cavity and fits against the end face of the first back panel 21.

[0051] Specifically, since the second back panel 22 is detachable, users can replace it with a second back panel 22 of different materials or patterns as needed. In other words, users can change the design of the second back panel 22 with different styles, colors and patterns according to their own preferences or trends, making it more personalized when it is applied to electronic devices such as mobile phones or tablets.

[0052] It should be noted that, in order to improve the heat dissipation of electronic devices such as mobile phones or tablets under high-performance operating conditions, the second back panel 22 can be removed from the second cavity, and the first back panel 21 can be removed from the receiving cavity 11 in the same way. This arrangement avoids the possibility that the materials of the first back panel 21 and the second back panel 22 may hinder heat dissipation when they cover the back of the electronic device, resulting in a large amount of heat not being able to be transferred to the outside. Through the opening of the protective cover body 1, the contact area between the back of the electronic device and the air is increased, which promotes the conduction and dissipation of heat.

[0053] The steel sheet 3 is disposed on the end face of the first rear panel 21 away from the second rear panel 22; the magnet block 4 is disposed on the end face of the second rear panel 22 near the first rear panel 21, for magnetic attraction with the steel sheet 3.

[0054] Specifically, the steel sheet 3 has good magnetic conductivity and is used as a carrier for magnet adsorption. By setting the magnet block 4 on the end face of the second back plate 22 near the first back plate 21, the magnet block 4 has magnetism and can generate a magnetic force to attract ferromagnetic materials. Therefore, when the magnet block 4 is close to the steel sheet 3 set on the first back plate 21, the steel sheet 3 can be attracted by the magnet, thus generating a strong attraction force to push the end face of the first back plate 21 and the end face of the second back plate 22 to attract each other and fit tightly together, so that the first back plate 21 and the second back plate 22 can be firmly attached. This arrangement not only facilitates the assembly and disassembly of the second back plate 22 or the first back plate 21, but also ensures the stability and firmness of the first back plate 21 and the second back plate 22 after they are attached.

[0055] It is understood that the magnet block 4 in this embodiment of the present invention is an N52 magnet, which has extremely high magnetic force compared to traditional magnets, so that the first back plate 21 and the second back plate 22 can be tightly attached.

[0056] according to Figure 2 and Figure 3 As shown, in some specific embodiments, the second back panel 22 is provided with multiple layers, and each layer of the second back panel 22 is stacked; multiple magnet blocks 4 are provided, and each magnet block 4 is respectively provided on the end face of each layer of the second back panel 22 that is close to the first back panel 21.

[0057] Specifically, users can change the material of the two second back panels 22 according to different actual usage needs. For example, the first second back panel 22 is a PC back panel, that is, a phone case back panel made of polycarbonate (PC) material. The PC material provides high toughness and impact resistance, effectively absorbing impact force when the electronic device is subjected to minor impacts or drops, protecting the internal components of the electronic device from damage. The second second back panel 22 is an IMD back panel, that is, decorative material is injected into this second back panel 22 through an injection molding process to simulate the surface texture or color of real materials. This simulates the appearance of various real materials such as metal, leather, wood, and marble, enriching the aesthetics of the product design and allowing it to match electronic devices with different design styles, thus satisfying users' pursuit of personalization. The two magnets 4 attract each other, causing their magnetic fields to interact and generate an attraction, allowing the two second back panels 22 to be tightly fitted and assembled into the first cavity.

[0058] In a further embodiment, each magnet block 4 is at the same height. This arrangement ensures that the two magnet blocks 4 are evenly attracted to each other, as they are respectively disposed on each of the second back plates 22 at the same height. Since the two magnet blocks 4 are at the same height, positional deviations are avoided, which would prevent the two magnets from attracting each other and affect the stability of the two second back plates 22.

[0059] In some specific embodiments, the end face of the second back plate 22 facing the first back plate 21 is recessed with a magnet positioning groove for accommodating the magnet block 4, and the outer side of the magnet block 4 is interference-fitted with the groove wall of the magnet positioning groove.

[0060] Specifically, when the end face of the first back panel 21 is in contact with the end face of the first back panel 21, the magnet block 4 is in an interference fit with the wall of the magnet positioning groove, which avoids a large gap between the magnet block 4 and the wall of the magnet positioning groove. This ensures that the magnet block 4 can be stably assembled in the magnet positioning groove, and prevents the magnet block 4 from moving or shifting when the user carries the protective case of the electronic device out.

[0061] It is understood that the magnet block 4 in this embodiment of the present invention is ring-shaped, and correspondingly, the receiving cavity 11 is an annular groove, ensuring that the ring-shaped magnet block 4 can be assembled in the magnet positioning groove, and the two can achieve an interference fit.

[0062] The steel sheet 3 in this embodiment of the present invention has a thickness of 0.8mm. With this setting, the 0.8mm thick steel sheet 3 can reduce material costs and the weight of the entire protective cover, while ensuring the magnetic attraction between the magnet and the steel sheet 3.

[0063] In some specific embodiments, the multilayer second back panel 22 includes at least a printed pattern back panel and a plastic back panel.

[0064] Specifically, the printed pattern back panel can be designed with different patterns and colors according to the user's preferences, such as brand logos and advertising slogans, to enhance the aesthetics of the protective case; the plastic back panel plays a certain role in shock resistance and cushioning, protecting electronic devices from external impacts and reducing the risk of damage to the electronic devices.

[0065] It should be noted that one end face of the aforementioned plastic back panel is attached to the first back panel 21, and the other end face of the plastic back panel is attached to the printed pattern back panel, with the end face of the printed pattern back panel exposed to the outside.

[0066] according to Figure 4 and Figure 5As shown, in some specific embodiments, the cavity wall of the accommodating cavity 11 is recessed with a first positioning groove, and the side of the first back plate 21 is provided with a first protrusion for being engaged in the first positioning groove; the cavity wall of the second accommodating cavity is recessed with a second positioning groove 121, and the side of the second back plate 22 is provided with a second protrusion 221 for being engaged in the second positioning groove 121.

[0067] Specifically, when it is necessary to disassemble the first back panel 21 and the second back panel 22, since the protective case body 1 is made of soft rubber, when disassembling the first back panel 21, the side of the protective case body 1 is bent to deform it until the first protrusion of the first back panel 21 can be disengaged from the first positioning groove, and then the entire first back panel 21 can be removed. The disassembly of the second back panel 22 is done in the same way, and the specific technical principle will not be explained in detail here. When it is necessary to assemble the first back panel 21 and the second back panel 22, the side of the protective case body 1 is bent to deform it until the first back panel 21 is assembled into the receiving cavity 11 and its first protrusion is engaged in the first positioning groove, and the second back panel 22 is assembled into the second receiving cavity and its second protrusion 221 is engaged in the second positioning groove 121. At this time, the assembly of the first back panel 21 and the second back panel 22 can be completed.

[0068] according to Figure 1 As shown, in some specific embodiments, an auxiliary touch component 5 is detachably provided on the side of the protective case body 1.

[0069] Specifically, since some mobile electronic devices are equipped with touch-sensitive buttons, that is, fingers are placed on the touch-sensitive buttons and slid to control a certain function, such as the Capture Button of the iPhone 16, in order to prevent the capture button from being easily scratched due to exposure, a touch-sensitive button is provided on the side of the protective case body 1 for attaching to the capture button of the phone, so as to protect the capture button without affecting the operation of the capture button.

[0070] according to Figure 7 and Figure 8 As shown, specifically, the auxiliary touch component 5 includes a button housing 51 and a plurality of conductive parts 52; a plurality of assembly cavities are formed hollowly along the length of the button housing 51, and each conductive part 52 is respectively disposed in each assembly cavity; the end face of the button housing 51 facing the accommodating cavity 11 has an opening for exposing one end of the conductive part 52.

[0071] Specifically, since the shooting button has multiple charge contacts, one end of each conductor in this embodiment is respectively attached to the multiple charge contacts on the shooting button, forming multiple independent charge transfer channels through the conductors, thus forming multiple charged points on the top surface of the shooting button. When the user's finger touches each charged point on the button housing 51, under the action of the human body's electric field, the user's finger and the shooting button form a coupling capacitor, which is used to trigger some of the charge contacts of the shooting button. At the same time, if the finger slides further on the button housing 51, the finger disconnects the previous charge contact and connects the next charge contact, thereby realizing the touch control of the shooting button.

[0072] according to Figures 6-8 As shown, in a further embodiment, the outer side of the button housing 51 is provided with two protruding rings 511, and the side of the protective sleeve body 1 is provided with a third positioning groove 13. The groove wall of the third positioning groove 13 is provided with an inner flange 131 for being engaged between the two protruding rings 511.

[0073] Specifically, the two protruding rings 511 on the side of the button housing 51 are a certain distance apart. When the inner flange 131 of the groove wall of the third positioning groove 13 is engaged between the two protruding rings 511, the two sides of the inner flange 131 abut against the two protruding rings 511 respectively, generating a certain friction force so that the button housing 51 is assembled in the third positioning groove 13, thereby stabilizing the entire auxiliary touch component 5. This design reduces the likelihood of the entire auxiliary touch component 5 shifting or falling off.

[0074] according to Figure 8 As shown, in some specific embodiments, the touch surface of the button housing 51 is also provided with an in-mode printing layer 512. This in-mode printing layer 512 is used to enhance personalized design, increase aesthetics, improve the product's appearance, and meet the user's aesthetic needs. Specifically, the in-mode printing layer 512 adds various patterns and designs to make its appearance more beautiful and in line with the user's aesthetic requirements. The in-mode printing layer also identifies different buttons or functions, helping users to more easily identify and use the touch keys. In other embodiments, the in-mode printing layer 512 has a textured design. This design can, to a certain extent, enhance the friction of the touch surface of the button housing 51, resulting in a better feel and stronger anti-slip properties when the user presses the button.

[0075] according to Figure 8 As shown, in a further embodiment, a protective layer 513 is also provided on the end face of the pattern printing layer 512 to protect the pattern printed on the surface of the article and prevent the pattern printing layer from being affected by factors such as wear, scratches and contamination during daily use. Therefore, the protective layer can effectively reduce damage.

[0076] For example, the protective layer 513 is a sheet of PC (polycarbonate) or TPU (thermoplastic polyurethane elastomer). As such, the protective layer 513 of the PC sheet has strong impact strength, which can resist impact and vibration. It also has corrosion resistance, which can protect the printed layer from chemical corrosion. The protective layer 513 of the TPU sheet has strong abrasion resistance, which can prevent the surface pattern from being scratched or worn. It also has excellent flexibility, which can be used to adapt to different surfaces and shapes.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
