Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a mobile phone case with a replaceable back panel and a compatible SIM card tray. Background Technology

[0002] A phone case is an accessory used to protect or decorate the appearance of a mobile phone. With the increasing variety of mobile phone brands and functions, phone cases have become more diverse. They can be categorized by material, including leather, silicone, cloth, hard plastic, leather cases, metal, soft plastic, velvet, and silk.

[0003] However, current phone case products on the market have certain technical shortcomings: First, most personalized phone cases use fixed designs, such as being molded as a single piece through in-mold injection molding or relying on accessories like adhesive rings to achieve decorative effects. Users cannot easily and without damage change the decorative patterns, resulting in a monotonous appearance that fails to meet users' needs for personalized looks in different situations or moods. Once users tire of the existing patterns, they have to replace the entire phone case, increasing usage costs and wasting resources. Second, traditional phone cases are usually designed only for specific phone models, with fixed structural dimensions. When users change their phone models, the original phone case becomes unusable, leading to a high product obsolescence rate and increased electronic waste. Currently, the market lacks a protective case solution that can be widely adapted to various electronic devices by replacing a few key components, thus limiting the product's versatility and sustainability.

[0004] Therefore, existing technologies are insufficient to meet users' needs for frequent and low-cost personalized changes to the appearance of their phone cases, nor can they achieve universal use of protective cases across different devices, thus requiring urgent improvement.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 4 As shown, this utility model claims protection for a mobile phone case with a replaceable back panel and an adapter card tray. The mobile phone case mainly includes a main frame 1, at least one decorative back panel 2, a first card tray 3, and a second card tray 4. The main frame 1 is the basic skeleton and supporting structure of the entire mobile phone case, and its overall design is shaped like an eyeglass frame, exhibiting a novel structure. The main frame 1 is made of high-strength engineering plastics such as PC, ABS, or a mixture of both, and is integrally molded using a fully enclosed in-mold injection molding process, thus giving the main frame 1 the characteristics of being sturdy, durable, and structurally stable.

[0031] To improve durability, a wear-resistant decorative coating, such as a rubberized paint layer, is applied to the surface of the main frame 1 to enhance the feel and scratch resistance. On the back of the main frame 1, facing the back of the phone, a mounting structure is provided for attaching the decorative back panel 2. The decorative back panel 2 is detachably mounted to the back of the main frame 1.

[0032] In this embodiment, a magnetic connection is preferably used. Specifically, several annular magnets or magnetic sheets can be embedded in the back edge of the main frame 1, and corresponding magnetic components can be embedded in the corresponding positions of the decorative back panel 2, enabling quick installation and replacement of the decorative back panel 2 through magnetic attraction. Of course, in other alternative embodiments, the connection method can also be a snap-fit ​​connection or a sliding groove connection.

[0033] Furthermore, the decorative back panel 2 is designed as two independent, mirror-shaped decorative panels, corresponding to the two mirror frame areas on the upper part of the main frame 1. The material of the decorative back panel 2 can be selected according to user preferences, such as metal, wood, or luminous materials, providing users with a wide range of personalized options. An obstruction hole 201 is also provided on the decorative back panel 2 to accommodate the camera of the electronic device, ensuring that the phone's camera function is not affected.

[0034] Furthermore, the first card holder 3 and the second card holder 4 are detachably connected to the left and right sides of the main frame 1, respectively, and are arranged opposite each other, both being arc-shaped. In this embodiment, the first card holder 3 and the second card holder 4 are connected to the main frame 1 by a snap-fit ​​mechanism. The left and right edges of the main frame 1 may have hooks, while the inner side of the card holder has matching slots, allowing for secure connection and easy disassembly by pressing. Similarly, in other embodiments, screws or magnetic attachment can be used for fixation.

[0035] The first SIM card tray 3, the second SIM card tray 4, and the main frame 1 together form an open cavity for mounting the mobile phone. This allows the mobile phone to be placed inside the open cavity. To more securely fix the mobile phone, both the first SIM card tray 3 and the second SIM card tray 4 have inwardly extending guard edges 5 on their inner sides. The guard edges 5 can partially cover the screen bezel of the mobile phone to prevent the mobile phone from flipping outward.

[0036] In addition, in order to ensure that the charging port, speaker, microphone and other functional interfaces of the mobile phone are not blocked, through holes 6 corresponding to the functional interfaces of the electronic device are provided on the first card tray 3 and / or the second card tray 4.

[0037] In addition, an outwardly protruding arc-shaped structure 101 can be provided in the middle area of ​​the main frame 1. The arc-shaped structure 101 helps to enhance the grip of the phone case and also achieves a certain anti-slip effect.

[0038] The first SIM card tray 3 and the second SIM card tray 4 are detachably connected to the main frame 1. This allows for easy replacement of the first SIM card tray 3 and the second SIM card tray 4 when using phones of different sizes. Users do not need to buy the entire phone case for each new device; they only need to purchase a pair of low-cost new SIM card trays, saving expenses and reducing resource waste.

[0039] This utility model features personalized customization. Users can easily achieve diverse changes in appearance style by simply replacing the decorative back panel 2 without replacing the entire phone case. Furthermore, when it is compatible with various phone models, only specific SIM card trays need to be replaced, reducing the cost of repeatedly purchasing accessories when changing phones. The structure is novel and highly innovative.

[0040] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
