Description
Technical Field
[0001] This utility model relates to the field of mobile phone protection technology, specifically to a foldable mobile phone screen protection device. Background Technology
[0002] With the increasing popularity of foldable phones, dedicated protective devices (such as protective cases) have become essential accessories. Current products typically consist of a first frame and a second frame protecting the sides of the phone, forming a folding groove to accommodate the hinge. To protect the exposed hinge area, a common solution is to add a separate protective strip or cover to the frame. However, these protective components are mostly separate from the frame body, secured by snap-fit or adhesive during assembly. This separate structure inherently suffers from reliability issues; for example, the protective components are prone to loosening and detachment, and additional seams and gaps are created at the joints, affecting the product's overall integrity and aesthetics. Furthermore, separate assembly increases manufacturing complexity and cost. Therefore, existing technologies still need improvement in creating a more robust and integrated structure between the hinge protection components and the frame.
[0003] Therefore, this utility model proposes a foldable mobile phone screen protection device. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model proposes a folding mobile phone screen protection device, which significantly improves the reliability of the connection and the integrity of the structure through an integrated hinge protection component and its built-in adsorption component.
[0005] The technical solution of this utility model is implemented as follows:
[0006] A foldable mobile phone screen protection device includes a first frame and a second frame for fitting over the mobile phone, with a folding groove formed between the first frame and the second frame; a hinge protection member is integrally connected to the first frame or the second frame, the hinge protection member extending from the corresponding frame towards the outside of the folding groove and covering the folding groove; the hinge protection member has a recessed groove on the side facing the folding groove, and an adsorption component is disposed in the groove.
[0007] Preferably, the first frame and the second frame are detachably connected.
[0008] Preferably, the first frame has a first open end on the side near the folding groove, and the second frame has a second open end on the side near the folding groove facing the first open end; the first open end has an insertion groove, and the second open end is connected to a flexible bending part, the first end of the flexible bending part has an insertion protrusion that inserts into the insertion groove.
[0009] Preferably, the head of the insertion protrusion is provided with a protrusion; one side wall of the insertion groove is provided with an insertion interface for the protrusion to be inserted, and the other side wall is provided with an arc slope; a limiting block is provided on the inner wall of the insertion groove where the insertion interface is provided, and the limiting block extends toward the arc slope.
[0010] Preferably, the flexible bending portion has a connecting rib in the middle that connects to the insertion protrusion, and a hollow groove located beside the connecting rib and communicating with the folding groove.
[0011] Preferably, the adsorption component includes a plurality of magnets, which are spaced apart along the length of the groove.
[0012] Preferably, the bottom of the groove has multiple countersunk holes, and the magnet is embedded in the countersunk holes accordingly.
[0013] Preferably, the surface of the groove is covered with a decorative piece for sealing.
[0014] Preferably, the hinge protection component is elongated and has a flexible connection between it and the frame it is connected to.
[0015] Preferably, a back panel is installed inside both the first frame and the second frame; a camera mounting slot is provided on the back panel of the first frame or the second frame; and / or, an annular groove is provided on one of the back panels of the first frame and the second frame.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] This solution integrates a hinge protector that extends from the frame body and covers the folding groove. A recessed groove on the side facing the folding groove accommodates the adsorption component. This structural design fundamentally solves the problems of loose connections and easy detachment of separate protective components in the prior art. The integrated connection eliminates assembly gaps and additional connection interfaces, making the hinge protector and frame a robust whole, fundamentally improving connection reliability and structural strength. Secondly, placing the adsorption component (such as a magnet) within the recessed groove, rather than exposing it directly or simply embedding it in the side, provides structural protection for the magnet, preventing it from falling off or being damaged by direct impact or friction. Furthermore, the embedded design makes the outer surface of the protective device smoother, avoiding component protrusions, ensuring smooth folding and unfolding of the phone, and improving the overall appearance and aesthetics of the product. Overall, this solution achieves effective hinge protection and folding adsorption while resulting in a more stable structure and a simpler, more unified appearance. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and for 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 utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figure 1 and Figure 2 This utility model provides a specific embodiment of a foldable mobile phone screen protection device. This device is mainly used to be fitted onto the outside of a foldable mobile phone, providing comprehensive protection for the phone's main frame, back, and the critical hinge area.
[0028] In this embodiment, the protective device mainly includes a first frame 1 and a second frame 2 for respectively fitting and covering the left and right halves of the mobile phone. The first frame 1 and the second frame 2 are spatially opposite each other, with a folding groove 4 reserved between them to accommodate the phone's own hinge mechanism. As the core innovation of this utility model, a hinge protection component 3 is integrally connected to the first frame 1 (or the second frame 2). Specifically, the hinge protection component 3 is formed as a whole with the connected frame (e.g., the first frame 1) during manufacturing, rather than being assembled later. The hinge protection component 3 extends obliquely from the inner edge of the first frame 1 towards the outer side of the folding groove 4 (i.e., the side away from the phone screen), and its main body is elongated, completely covering the top of the folding groove 4, thereby providing physical isolation and dust and impact protection for the phone's hinge.
[0029] Furthermore, to ensure that the hinge protector 3 provides rigid coverage while adapting to the slight deformation during the opening and closing of the phone and avoiding interference, a flexible connecting part 33 is integrally formed at the connection root between the hinge protector 3 and the first frame 1. The material of this flexible connecting part 33 has higher elasticity and fatigue resistance than the frame body, allowing the hinge protector 3 to bend slightly elastically relative to the frame as a whole. This maintains the stability of the coverage when the phone is repeatedly folded and unfolded, without generating excessive internal stress or hindering the normal movement of the phone.
[0030] Please continue reading. Figure 1 and Figure 2On the side of the hinge protector 3 facing the downward folding groove 4, a strip-shaped groove 31 extending along its length is recessed into its surface. An adsorption assembly is disposed within the groove 31. In a preferred embodiment, the adsorption assembly includes a plurality of magnets 32 spaced apart along the length of the groove 31. The function of these magnets 32 is to attract corresponding magnetic elements inside the phone casing or on the other side frame when the foldable phone is in the closed state, thus maintaining a stable folded state.
[0031] To optimize the fixation and protection of the magnets 32, multiple countersunk holes (not shown individually in the figure) matching the shape and size of the magnets 32 are formed at the bottom of the groove 31. Each magnet 32 is embedded in a corresponding countersunk hole, with its adsorption surface slightly lower than or flush with the groove opening plane of the groove 31. This embedded design effectively prevents the magnets 32 from being worn, scratched, or falling off due to exposure. In addition, to improve aesthetics and prevent dust from entering, after the magnets 32 are installed, a decorative piece (such as a metal sheet or a colored PET sheet) can be pasted onto the surface of the groove 31 to seal the groove 31.
[0032] Please see Figures 1 to 4 In this embodiment, the first frame 1 and the second frame 2 are detachably connected, which facilitates user installation and replacement. The specific connection structure is as follows: a first opening end 11 is provided on the edge of the first frame 1 near the folding groove 4, and correspondingly, a second opening end 21 is provided on the edge of the second frame 2 near the folding groove 4.
[0033] The first open end 11 has a insertion groove 111. The second open end 21 is connected to an outwardly extending flexible bending portion 22, which is made of an elastic material (such as TPU). At the free end of the flexible bending portion 22, an inwardly protruding insertion protrusion 221 is provided. During installation, the second frame 2 is brought closer to the first frame 1, so that the insertion protrusion 221 is aligned and inserted into the insertion groove 111, thereby achieving a quick connection between the two frames.
[0034] To ensure a secure connection and a locking function, the head of the insertion protrusion 221 is provided with a protrusion 2211. Correspondingly, one side wall of the insertion groove 111 has an insertion interface 1111 for the protrusion 2211 to slide into, while the other side wall is designed as a smooth arc slope 1113. On the inner wall of the insertion groove 111 where the insertion interface 1111 is located, a limiting block 1112 extending towards the arc slope 1113 is also provided. When the insertion protrusion 221 is inserted into the insertion groove 111, the protrusion 2211 slides in along the guiding deformation of the arc slope 1113 until it is engaged with the rear of the insertion interface 1111, and its end abuts against the top of the limiting block 1112, thereby being locked and preventing easy dislodgement.
[0035] To enhance the structural strength of the flexible bending section 22 and control its bending deformation area, a connecting rib 222 is provided in its middle. At the same time, a hollow groove 223 is provided on the side of the connecting rib 222. The hollow groove 223 is connected to the folding groove 4, which not only reduces weight but also provides space for bending, ensuring the flexibility of the connecting part when the phone is folded.
[0036] Regarding materials, as a preferred option, the first frame 1, the second frame 2, and the integrated hinge protection component 3 (including the flexible connection part 33) can be molded using thermoplastic polyurethane elastomer (TPU) or thermoplastic elastomer (TPE) through two-color injection molding or one-piece injection molding processes to achieve good elasticity, cushioning, and durability. A back panel (not shown in the figure) is installed on the inner side of both the first frame 1 and the second frame 2. The back panel is preferably made of a rigid material such as polycarbonate (PC) to provide rigid support for the back of the phone. A camera mounting slot can be provided on the back panel to match the phone lens, or a ring groove can be provided on one side of the back panel to embed a magnetic ring, enhancing the adhesion to external accessories.
[0037] Working Principle and Beneficial Effects: The protective device provided in this embodiment, by integrally molding the hinge protection component 3 with the frame (1 or 2), fundamentally eliminates the problems of connection gaps and easy loosening and detachment existing in traditional split protective covers, significantly improving structural integrity and reliability. The integrally molded flexible connection part 33 gives this rigid protective component the necessary degree of freedom of movement, perfectly adapting to the dynamic usage scenarios of folding phones. The array of magnets 32 built into the groove 31 not only provides a stable folding adsorption force, but its embedded design also provides ample protection, and the appearance is flat and beautiful. At the same time, the precisely designed detachable plug-in structure between the first frame 1 and the second frame 2 greatly facilitates user disassembly and assembly while ensuring a stable connection. In summary, this utility model achieves an effective unity of protection, reliability, practicality, and aesthetics.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
