Description

Technical fields:

[0001] This utility model relates to the field of smart device accessories technology, and specifically refers to a leather-covered folding mobile phone protective case. Background technology:

[0002] With the rapid development of smartphones and the increasingly fast iteration speed of manufacturers, smartphone screen sizes are becoming larger and larger. However, excessively large sizes are not only inconvenient to carry but also unfriendly to users with small hands. Therefore, to attract users' attention, major manufacturers have successively launched foldable phones, which have been widely favored by users. Foldable phones typically consist of a first body and a second body that are hinged together. The first body has a first screen, and the second body has a second screen. When needed, the first and second bodies can be opened, for example, at a 180-degree angle, at which point the first and second screens join together to form the phone's screen. When not in use, the user can rotate the first and second bodies so that the first and second bodies are stacked, thus effectively reducing the size of the phone and making it easier to carry. However, due to the structural design, conventional phone cases cannot be used with foldable phones.

[0003] Currently available foldable phone cases offer protection for foldable phones. For example, Chinese utility model patent application CN221784228U discloses a foldable phone case comprising a front shell, a middle shell, a rear shell, and a hinge assembly. The hinge assembly includes a metal hinge plate and a pivot assembly rotatably connected to the metal hinge plate. The pivot assembly is mounted on the rear shell, and the metal hinge plate is connected and fixed to the middle shell. Alternatively, the metal hinge plate and the middle shell are injection molded as inserts; or, the metal hinge plate is riveted to the middle shell. This technical solution provides a method that protects the hinge axis of the foldable phone while also meeting the needs of frequent folding, preventing the middle component from separating from the front and / or rear protective shells.

[0004] However, these existing folding phone cases still have the following shortcomings:

[0005] In this technical solution, the back cover and front cover are connected by a hinge assembly. However, the hinge assembly contains a number of small and precision parts, which not only makes assembly difficult during production, but also makes the performance affected by friction wear over a long period of use. In addition, the hinge assembly has the characteristics of high rigidity and poor swing flexibility. Furthermore, due to the limitations of machine conditions and slight errors in the size of the parts, it is difficult to guarantee the quality control of the swing trajectory of the hinge assembly. Since the internal structure of a foldable phone is very delicate, long-term use of a phone case with a hinge assembly may interfere with the internal hinge structure of the foldable phone, thereby shortening the lifespan of the foldable phone.

[0006] In view of the above, the inventors propose the following technical solution. Utility model content:

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a foldable, leather-like mobile phone protective case.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a foldable mobile phone protective case, comprising: a first shell, which is used to fit a first body of a foldable mobile phone; a second shell, which is disposed on the first shell in a swingable and foldable manner and is used to fit a second body of the foldable mobile phone; a folding connecting layer, one end of which is fixed to the first shell and the other end of which is fixed to the second shell, and the folding connecting layer forms a folding bend between the first shell and the second shell; the bend is further provided with a hanging ring assembly for connecting a lanyard assembly.

[0009] Furthermore, in the above technical solution, the hanging ring assembly includes a soft leather layer disposed on the bending portion and used for contacting the foldable mobile phone, a first buckle and a second buckle fixed on the soft leather layer and passing through the bending portion, a first hanging ring connected to the first buckle, and a second hanging ring connected to the second buckle.

[0010] Furthermore, in the above technical solution, the bent portion is provided with a first clearance hole for the first buckle to pass through and extend outward; the bent portion is also provided with a second clearance hole for the second buckle to pass through and extend outward.

[0011] Furthermore, in the above technical solution, the hanging rope assembly includes a first rope body connected to the first buckle ear and a second rope body connected to the second buckle ear. The first rope body has an adjustment ring at its end for the second rope body to pass through, and the first rope body also has several adjustment holes. Correspondingly, the second rope body has an adjustment buckle at its end, so that the first rope body can be adjusted and mounted on the second rope body.

[0012] Furthermore, in the above technical solution, the back of the first housing is recessed to form a first recessed groove for accommodating the folded connecting layer; the back of the second housing is recessed to form a second recessed groove for accommodating the folded connecting layer.

[0013] Furthermore, in the above technical solution, the second housing has a second clearance portion for the foldable phone to be exposed outward, and correspondingly, the folding connecting layer has a first clearance portion.

[0014] Furthermore, in the above technical solution, the folded connecting layer includes a first decorative part that is pasted and fixed in the first recessed groove, a second decorative part that is integrally formed with the first decorative part and pasted and fixed in the second recessed groove, and a bent part formed between the first decorative part and the second decorative part.

[0015] Furthermore, in the above technical solution, the folded connecting layer is integrally extruded using PU material; the material of the first shell is at least one of silicone, TPU, and PC, and the material of the second shell is at least one of silicone, TPU, and PC.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In the present invention, the first shell 1 and the second shell are connected by a folding connecting layer, forming a bending part that is easy to fold, eliminating the traditional hinge structure, effectively achieving mechanical performance matching between the folding connecting layer and the first and second shells, improving flexibility, and without too many small parts, facilitating production management. There is no need to worry about wear and tear even after long-term use, making it suitable for widespread application in various folding mobile phone cases. In addition, compared with the existing structure, the present invention adds a hanging ring assembly to the bending part, thereby enabling the connection of a lanyard assembly, effectively improving portability.

[0020] Figure 4 This is a cross-sectional schematic diagram of the present invention after removing the lifting ring assembly. Detailed implementation method:

[0021] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0022] See Figures 1 to 4As shown, a foldable mobile phone case includes: a first housing 1 for fitting a first body of a foldable mobile phone; a second housing 2, which is foldable and mounted on the first housing 1 for fitting a second body of the foldable mobile phone; a folding connecting layer 3, one end of which is fixed to the first housing 1 and the other end of which is fixed to the second housing 2, and the folding connecting layer 3 has a folding portion 33 between the first housing 1 and the second housing 2 for easy folding; the folding portion 33 is also provided with a hanging ring assembly 5 for connecting a lanyard assembly 4.

[0023] In this invention, the first housing 1 and the second housing 2 are connected by a folding connecting layer 3, forming a folding bend 33 that facilitates folding. This eliminates the need for a traditional hinge structure, effectively achieving a match between the mechanical properties of the folding connecting layer 3 and the first and second housings 2, improving flexibility. Furthermore, the absence of numerous small parts facilitates production management, and wear and tear is not a concern even after prolonged use, making it suitable for widespread application in various folding phone cases. In addition, compared to existing structures, this invention adds a hanging ring assembly 5 to the bend 33, enabling the connection of a lanyard assembly 4, effectively enhancing portability.

[0024] The hanging ring assembly 5 includes a soft base layer 51 disposed on the bending portion 33 for contact with the foldable phone, a first latch 52 and a second latch 53 fixed to the soft base layer 51 and passing through the bending portion 33, a first hanging ring 54 connected to the first latch 52, and a second hanging ring 55 connected to the second latch 53. The bending portion 33 has a first clearance hole 331 for the first latch 52 to pass through and extend outward; the bending portion 33 also has a second clearance hole 332 for the second latch 53 to pass through and extend outward. Here, since the first latch 52 and the second latch 53 need to be added to the bending portion 33, and the bending portion 33 is relatively thin, a soft base layer 51 needs to be adhered to the bending portion 33 to secure the first latch 52 and the second latch 53, while also increasing the thickness of the bending portion 33 and improving stability.

[0025] The lanyard assembly 4 includes a first rope 41 connected to the first buckle 52 and a second rope 42 connected to the second buckle 53. The first rope 41 has an adjusting ring 411 at its end for the second rope 42 to pass through, and several adjusting holes 412 are also provided on the first rope 41. Correspondingly, the second rope 42 has an adjusting buckle 421 at its end, allowing the first rope 41 to be adjusted and positioned on the second rope 42. This added lanyard assembly 4 effectively improves portability, enhances the user experience, and allows for quick adjustment of the tightness of the first rope 41 and the second rope 42 via the adjusting ring 411.

[0026] The first housing 1 has a recessed groove 101 on its back for accommodating the folded connecting layer 3; the second housing 2 has a recessed groove 202 on its back for accommodating the folded connecting layer 3. Here, both the first housing 1 and the second housing 2 are injection molded, and the first groove 101 and the second groove 202 are pre-formed during injection molding. The depths of the first groove 101 and the second groove 202 are the same as the thickness of the folded connecting layer 3. The folded connecting layer 3 is bonded to the first housing 1 and the second housing 2 using a hot-pressing composite process.

[0027] The second housing 2 has a second clearance portion 201 for the foldable phone to be exposed outwards, and correspondingly, the folding connecting layer 3 has a first clearance portion 301. In this embodiment, since some foldable phones on the market also have a display screen on the back of the second body, it is necessary to open a second clearance portion 201 on the second housing 2 to expose the display screen outwards.

[0028] The folded connecting layer 3 includes a first connecting portion 31 that is glued and fixed within the first recessed groove 101, a second connecting portion 32 that is integrally formed with the first connecting portion 31 and glued and fixed within the second recessed groove 202, and a bent portion 33 formed between the first connecting portion 31 and the second connecting portion 32. Here, the folded connecting layer 3 also serves a decorative function, allowing for personalized customization of patterns, colors, surface textures, and tactile feel, thus better meeting the needs of different users.

[0029] The folded connecting layer 3 is integrally extruded from PU material; the first shell 1 is made of at least one of silicone, TPU, and PC, and the second shell 2 is made of at least one of silicone, TPU, and PC; the folded connecting layer 3 is connected to the first shell 1 and the second shell 2 by hot pressing.

[0030] In summary, this invention connects the first housing 1 and the second housing 2 via a folding connecting layer 3, forming a folding bend 33 that facilitates folding. This eliminates the need for traditional hinge structures, effectively achieving a match between the mechanical properties of the folding connecting layer 3 and the first and second housings 2, enhancing flexibility. Furthermore, the absence of numerous small parts facilitates production management, and wear and tear is not a concern even after prolonged use, making it suitable for widespread application in various folding phone cases. Additionally, compared to existing structures, this invention adds a hanging ring assembly 5 to the bend 33, enabling the connection of a lanyard assembly 4, effectively improving portability.
