Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, and in particular to a universal mobile phone case that can be adapted to various mobile phone models. Background Technology

[0002] With the rapid development and iteration of smartphone technology, users are replacing their mobile devices more frequently. As an essential accessory for mobile phones, the protective case market is booming. However, most mobile phone cases on the market still adopt a dedicated design model, meaning that a single case can only perfectly fit a specific phone model. This model means that when users switch to a new phone, the previously purchased case often becomes unusable due to size or opening mismatch. This not only imposes an economic burden on users to make repeated purchases but also causes serious waste of resources, increases electronic waste, and impacts environmental pollution.

[0003] To address this issue, some generic phone case designs have emerged on the market. These designs typically use flexible materials such as elastic bands or mesh to wrap the phone, or simply provide an oversized cavity to accommodate phones of different sizes. However, these structures have certain technical drawbacks: the phone can wobble or even slip out of the case, resulting in insecure fixation and failing to provide adequate protection. Furthermore, overly large bezels or loose structures can obstruct the screen and interfere with the normal use of buttons and ports.

[0004] Therefore, there is an urgent need in this field for a new solution that can truly enable a single phone case to be stably adapted to multiple phone models, improving the protection of the phone and the user experience, and fundamentally solving the technical problem of one case serving multiple purposes. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a universal phone case that can be adapted to various phone models, thus solving the defects mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A universal phone case that can be adapted to various phone models includes a case body, the case body including a back panel and a frame extending from the periphery of the back panel, the back panel and the frame together surround and form an accommodating cavity for accommodating the phone; the four corners of the inner side of the frame are respectively provided with independent elastic support units. The elastic support unit includes a base connected to the frame and an arc-shaped support member protruding from the base toward the center of the accommodating cavity; The elastic support unit is made of elastic material. When the mobile phone is placed into the receiving cavity, it contacts the corner of the mobile phone through the arc-shaped support and clamps and fixes the mobile phone by the rebound force generated by its own elastic deformation.

[0007] Furthermore, the back panel is provided with a camera opening, the opening profile of which is larger than the camera module of all target compatible mobile phone models.

[0008] Furthermore, the edge of the camera opening is provided with a raised buffer ring; when the phone case is laid flat, the top of the buffer ring is lower than the surface height of the phone camera module.

[0009] Furthermore, the elastic support unit and the housing body are integrally injection molded.

[0010] Furthermore, the elastic material is thermoplastic polyurethane or silicone.

[0011] Furthermore, the elastic support unit is a continuous strip structure extending along the inner wall of the frame.

[0012] Furthermore, streamlined recesses are formed on the outer surfaces of the opposite side frames of the housing body.

[0013] Furthermore, the width of the camera opening is 39mm to 40mm, and the height is 40mm to 42mm.

[0014] Furthermore, the frame extends toward the inner edge of the accommodating cavity with a flange, which partially covers the peripheral area of ​​the mobile phone screen.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention cleverly transforms the slight differences in overall dimensions (length, width, thickness, etc.) of different mobile phone models into varying degrees of compression for the four corner elastic support units by providing independent elastic support units at each of the four corners. Thus, regardless of changes in phone size, the elastic support units can generate a matching rebound clamping force through their own elastic deformation for fixation. This ensures compatibility with multiple mobile phone applications, eliminating the need for users to purchase new phone cases after upgrading to a new generation. It fundamentally solves the problem of accessory waste caused by rapid mobile phone iteration, offering both convenience and economic benefits. Attached Figure Description

[0016] The accompanying drawings are provided to further illustrate the present invention and, together with the embodiments of the present invention, are used to explain the present invention. They do not constitute a limitation thereof. In the drawings: Figure 1 It's a universal phone case that creates a 3D effect when the phone is placed inside.

[0018] 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.

[0019] like Figures 1 to 5 As shown, this utility model claims protection for a universal phone case that can adapt to multiple phone models, helping to solve the compatibility problem between traditional single phone cases and phones of various sizes. Specifically, the phone case includes a case body, which comprises two main parts: a back panel 1 and a frame 2. The back panel 1 is mainly used to cover and protect the back of the phone. The frame 2 extends from the periphery of the back panel 1, and together with the back panel 1, forms a receiving cavity with an opening at the top, through which the phone 4 is placed.

[0020] The main feature of this invention lies in the independent elastic support units 3 located at the four corners of the inner side of the frame 2. Each elastic support unit 3 includes a base 301 and an arc-shaped support member 302. The base 301 is firmly connected to the inner wall of the frame 2, serving as the fixed foundation for the entire support unit. In one preferred embodiment, the base 301 and the frame 2 are integrally injection molded, ensuring the integrity and strength of the structure.

[0021] from Figure 4 As can be seen, the arc-shaped support 302 protrudes from the base 301 towards the center of the accommodating cavity, and its outer surface forms an arc-shaped surface that approximates or matches the arc-shaped profile (i.e., R-angle) of the corner of the mobile phone. The arc-shaped support 302 is made of a material with good resilience, such as thermoplastic polyurethane or silicone. These materials not only provide the necessary elasticity, but also have cushioning, anti-slip, and wear-resistant properties.

[0022] When the user places the phone 4 into the receiving cavity, the four corners of the phone 4 will first contact and compress the four curved support members 302. Due to the overall size differences between different phone models, the compression amount of the phone corners on these four support points will vary. That is, larger phones will exert greater compression on the curved support members 302, while smaller phones will exert less compression. Regardless of the compression amount, the elastic support unit 3 will generate a continuous rebound force directed towards the corners of the phone through its own elastic deformation. This rebound force ultimately acts from the four corners of the phone, thereby defining the phone's position and achieving a secure, wobbly clamping fixation.

[0023] In this embodiment, to accommodate the differences in size, shape, and position of camera modules 401 across different mobile phone models, the outline of the camera opening 101 in this invention is designed to cover the maximum external shape of the camera module 401 for all target compatible mobile phone models. In other words, the size and position of the camera opening 101 ensure that all cameras and sensors of the target mobile phones, from the smallest to the largest, are fully exposed without any obstruction. In this embodiment, the target compatible mobile phones mainly refer to Apple iPhone series communication devices, especially the following model ranges: iPhone 12 Pro Max to iPhone 16 Pro Max, iPhone 12 Pro to iPhone 16 Pro, and the basic iPhone 12 to iPhone 16 series.

[0024] Furthermore, a raised buffer ring 102 is provided around the edge of the camera opening 101. This buffer ring 102 is also made of elastic material. When the phone case is placed flat on a table, that is, when the outer surface of the back panel 1 contacts the table, the top of the buffer ring 102 is lower than the surface height of the outermost lens of the phone camera module 401. Therefore, when the phone is placed face down, the buffer ring 102 contacts the table before the camera, effectively preventing scratches to the camera.

[0025] In a specific size embodiment, the camera opening 101 can be a rounded rectangle with a width between 39mm and 40mm and a height between 40mm and 42mm. This size range has been tested and found to be compatible with the camera layout of the target compatible mobile phone model.

[0026] In this embodiment, the elastic support unit 3 is preferably a continuous strip structure extending along the inner wall of the frame 2. This strip structure provides a larger contact area and a more uniform stress distribution, making the fixation more stable and reliable.

[0027] Furthermore, streamlined recesses can be machined into the outer surfaces of the opposite side bezels 2 of the housing body. These streamlined recesses are ergonomically designed for a more stable and comfortable grip on the phone.

[0028] The inner edge of the frame 2 facing the opening of the cavity can extend horizontally inward to form a flange 201. This flange 201 can partially cover the non-display area around the periphery of the mobile phone screen. This not only helps to enhance the compactness of the phone case and the phone, but also provides an extra layer of protection for the screen when it is subjected to a frontal impact without obstructing the effective display content, preventing the screen from directly contacting the ground or hard objects.

[0029] This invention cleverly transforms the slight differences in overall dimensions (length, width, thickness, etc.) of different mobile phone models into varying degrees of compression for the four corner elastic support units by providing independent elastic support units at each of the four corners. Thus, regardless of changes in phone size, the elastic support units can generate a matching rebound clamping force through their own elastic deformation for fixation. This ensures compatibility with multiple mobile phone applications, eliminating the need for users to purchase new phone cases after upgrading to a new generation. It fundamentally solves the problem of accessory waste caused by rapid mobile phone iteration, offering both convenience and economic benefits.

[0030] 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.
