[0002] Mobile phones are a very common communication tool, now ubiquitous, with almost everyone owning one or more. A mobile phone mainly consists of components such as a screen, control motherboard, battery, mid-frame, and casing. With the rise of smartphones, phone screens are getting larger, which in turn requires larger casings, posing a significant challenge to the structural rigidity of the casing.
[0003] Insufficient rigidity in a phone casing can reduce its drop resistance. Some existing technologies employ a plastic-encased steel strip injection molding process for the phone's mid-frame to improve its structural rigidity and overall strength. This method requires placing the steel strip inside the injection mold during the mid-frame injection molding process. This not only increases injection molding time and reduces efficiency, but also places higher demands on the injection mold, increasing design complexity and inevitably raising the manufacturing cost of the mid-frame.

[0022] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.
[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.
[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0025] like Figure 1-7 As shown, a mobile phone includes a casing 1, a mid-frame, and a screen 2. A control board 3 is installed on the mid-frame. The casing 1 is fitted around the periphery of the mid-frame. The screen 2 is fixedly connected to the casing 1 and electrically connected to the control board 3.
[0026] The middle frame includes a frame body 4 and a cover plate 5. The cover plate 5 covers the frame body 4 and is fixedly connected to the frame body 4 by screws. Mounting grooves 41 are provided on the left and right sides of the frame body 4. Rigid metal strips 6, adapted to the width of the mounting grooves 41, are installed in the mounting grooves 41 and connect with the side walls of the mounting grooves 41. The connection between the rigid metal strips 6 and the side walls of the mounting grooves 41 reduces the clearance between them, thereby improving the overall structural rigidity of the frame body 4. Limiting blocks 51 are provided on the end face of the cover plate 5 at corresponding positions to the mounting grooves 41. When the cover plate 5 is placed on the frame body 4, the limiting blocks 51 can extend into the corresponding mounting grooves 41 and abut against the end faces of the rigid metal strips 6. By setting the limiting blocks 51 on the cover plate 5, the rigid metal strips 6 are limited within the mounting grooves 41, preventing displacement of the rigid metal strips 6, improving structural stability, and ensuring the rigidity and strength of the middle frame.
[0027] The phone's mid-frame enhances its overall structural rigidity by installing rigid metal strips 6 on both sides of the frame 4, thereby improving the phone's drop resistance. Furthermore, by encapsulating the rigid metal strips 6 within the frame 4 and the cover plate 5, the injection molding process of plastic encapsulating metal is eliminated. This reduces the injection molding time of the frame 4, improving efficiency, and also lowers the design complexity of the mold, thus better controlling the manufacturing cost of the phone's mid-frame and enhancing its market competitiveness.
[0028] To facilitate the installation and positioning of the rigid metal strip 6, a locking block 42 is provided on the side wall of the mounting groove 41. The height of the locking block 42 is adapted to the height of the rigid metal strip 6. After the rigid metal strip 6 is installed into the mounting groove 41, the locking block 42 can be locked and positioned against the upper end face of the rigid metal strip 6. By providing the locking block 42 on the side wall of the mounting groove 41, it is convenient to position the rigid metal strip 6 in the mounting groove 41. When installing the rigid metal strip 6 into the mounting groove 41, simply squeeze the rigid metal strip 6 into the mounting groove 41 until the limiting block 51 abuts against the rigid metal strip 6, indicating that the rigid metal strip 6 has been installed in place.
[0029] To secure the rigid metal strip 6 within the mounting slot 41, multiple limiting screws 43 are installed on the frame 4, each abutting against the upper surface of the rigid metal strip 6. During assembly, after the rigid metal strip 6 is installed into the mounting slot 41, the limiting screws 43 are screwed into the frame 4 until they abut against the upper surface of the rigid metal strip 6. The limiting screws 43 effectively secure the rigid metal strip 6 within the mounting slot 41, preventing displacement during phone use and improving structural stability.
[0030] The frame 4 has a battery slot 44, in which a battery 7 is installed. The battery 7 is electrically connected to the control board 3 and is used to power the mobile phone to meet daily use.
[0031] A camera 8 is installed on the cover plate 5. The camera 8 is electrically connected to the control board 3. A camera hole 11 is provided on the rear end face of the housing 1. After the housing 1 is fitted onto the outer perimeter of the middle frame, one end of the camera 8 extends out of the camera hole 11, so that the camera 8 can meet the daily shooting needs.
[0032] A camera decorative piece 9 is provided on the rear surface of the outer casing 1. The camera decorative piece 9 is fitted around the camera 8 extending from the camera hole 11, thereby enhancing the aesthetic appearance of the phone. The camera decorative piece 9 is detachably connected to the outer casing 1. In existing technologies, the camera decorative piece 9 is installed inside the outer casing 1, and can only be removed by disassembling the outer casing 1. In this invention, the camera decorative piece 9 is installed on the rear surface of the outer casing 1 and is detachably connected to the outer casing 1, allowing users to replace the camera decorative piece 9 according to their preferences, thereby changing the appearance of the phone to meet the personalized usage needs of different users and improve user experience.
[0033] In this embodiment, a removable adhesive coating is provided on the mating surface between the camera decorative part 9 and the housing 1, thereby detachably bonding the camera decorative part 9 to the housing 1 through the removable adhesive coating. Any existing removable adhesive can be used; various adhesive strengths are available on the market, and customized adhesives with suitable adhesive strengths can also be made according to actual usage. When the user needs to replace the camera decorative part 9, they simply need to forcefully pull the camera decorative part 9 off the housing, apply the removable adhesive to the new camera decorative part 9, and then attach it to the periphery of the camera 8 to complete the replacement of the camera decorative part 9. No tools are required, making the operation simple and convenient.
[0034] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model.
