Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, and in particular to a mobile phone case with a multi-functional patch. Background Technology

[0002] With the popularization and continuous upgrading of smart mobile terminal devices, phone cases, as important accessories for protecting phone hardware and showcasing user personality, have long since transcended the scope of simple drop protection. In order to meet users' needs for aesthetics and practical scenarios such as car mount attachment, a large number of phone case products with exquisite printed patterns or integrated magnetic functions have appeared on the market. These products have enriched the user experience of phone cases and have become the mainstream choice in the market.

[0003] However, in existing related technical solutions, most phone cases, in order to reduce the difficulty of manufacturing processes, directly place decorative pattern layers, reflective layers, and magnetic patches for fixing on the outer surface of the phone case. This exposed structural design reveals obvious defects during long-term use. Since the outer surface of the phone case is the area that comes into most frequent contact with the outside world, the external patterns or patches will inevitably be corroded by hand sweat and repeatedly physically rubbed against tabletops, clothing, and other external objects. This causes the exquisite patterns to suffer severe scratches, wear, and even peeling after a period of time. This not only damages the overall aesthetics of the product, but the external functional patches also disrupt the flatness of the back of the phone, making them very easy to fall off and become ineffective due to scratches. Existing technologies do not have replaceable patches with different functions, making it impossible to provide long-lasting protection while also taking into account aesthetics and multiple functions such as mosquito repellency, reflection, and fluorescence.

[0004] Therefore, this utility model proposes a mobile phone case with a multi-functional patch to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, decorative patterns and functional patches on mobile phone cases are directly set on the outer surface, which easily leads to scratches, wear, fading, and even peeling due to frequent contact with external friction during long-term use. In addition, the external magnetic components disrupt the flatness of the back of the phone and are prone to falling off under force. It is impossible to provide long-lasting protection while taking into account aesthetics and functional durability. The purpose of this utility model is to provide a mobile phone case with a multi-functional patch with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a mobile phone case with a multi-functional patch, including: a transparent rubber mobile phone case, and a magnetic ring, a magnet and a multi-functional patch disposed inside the transparent rubber mobile phone case.

[0007] The transparent rubber phone case has a groove on its inner wall, and a magnetic ring is fixedly connected to the inner wall of the groove. The transparent rubber phone case also has a fixing groove on its inner wall, and a magnet is fixedly connected to the inner wall of the fixing groove. The multifunctional patch is adhesively connected to the center of the inner wall of the transparent rubber phone case, and the multifunctional patch is located on the surface of the inner wall of the transparent rubber phone case.

[0008] Furthermore, the magnetic ring, the magnet, and the multifunctional patch are combined through a specific spatial layout. The magnetic ring is arranged around the outer periphery of the multifunctional patch, and the fixing groove is arranged around the outer periphery of the groove, thereby forming a layered magnetic and decorative structure on the inner wall of the transparent rubber phone case.

[0009] Preferably, the outer wall of the transparent rubber phone case has multiple outer hollow grooves, which penetrate the outer wall of the transparent rubber phone case to the inner wall of the transparent rubber phone case, providing a physical channel for connecting external devices to the phone and exposing the buttons directly for easy operation.

[0010] Preferably, the inner wall of the transparent rubber phone case has multiple heat dissipation holes, which are evenly distributed in an array on the inner wall surface of the transparent rubber phone case to reduce the contact area between the back of the phone and the phone case and to form an air buffer layer to assist in heat dissipation.

[0011] Preferably, the shape of the groove is adapted to the shape of the magnetic ring, the magnetic ring is fixed in the groove in an embedded manner, and the surface of the magnetic ring is on the same plane as the inner wall surface of the transparent rubber phone case to ensure the flatness of the internal structure and prevent scratches on the back of the phone.

[0012] Preferably, the depth of the fixing groove is greater than or equal to the thickness of the magnet, and the magnet is fixed in the fixing groove by an interference fit to ensure that the magnet is securely installed and does not protrude from the inner wall surface.

[0013] Preferably, the fixing groove is disposed between the outer periphery of the groove and the edge of the transparent rubber phone case, and there are multiple magnets, which are symmetrically distributed on the inner wall of the transparent rubber phone case, thereby forming an enhanced and uniform magnetic adsorption field in conjunction with the magnetic ring.

[0014] Preferably, the multifunctional patch is an adhesive sticker, which includes a reflective coating and a fluorescent coating. The patterned side of the multifunctional patch faces the outside of the transparent rubber phone case, and is used to display the pattern through the transparent case and provide reflective warning and fluorescent positioning functions.

[0015] Preferably, the transparent rubber phone case is made of thermoplastic polyurethane elastomer material. The transparent rubber phone case is transparent in all aspects, so as to utilize the high light transmittance of the material to display the internal structure and pattern and provide elastic protection.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem that existing ordinary phone cases lack magnetic fixation function or require additional external magnetic sheets, resulting in poor feel and affecting aesthetics, by setting grooves and fixing slots on the inner wall of the transparent rubber phone case and embedding fixing magnetic rings and magnets respectively. It achieves the ability to easily attach the phone to ferrous objects such as car mounts or refrigerator doors to adapt to various usage scenarios. Moreover, the embedded flat design ensures that the magnetic components do not protrude, effectively preventing scratches on the back of the phone.

[0018] 2. This utility model solves the problem that the decorative patterns printed on the outer surface of mobile phone cases are easily scratched, faded, or peeled off due to daily friction by using a transparent material and a multi-functional patch that is pasted on the inner wall. It achieves the goal of displaying the internal pattern with a transparent shell while providing physical isolation and protection, ensuring that the pattern remains new for a long time. By changing the patches with different effects, it can achieve various effects such as mosquito repellency, reflection, and fluorescence, meeting users' needs for personalized appearance and diverse functions of mobile phone cases.

[0019] 3. This utility model solves the problems of heat accumulation and stiff side button operation of traditional fully enclosed rubber phone cases by opening evenly distributed heat dissipation holes on the inner wall of the transparent rubber phone case and opening through-type outer hollow grooves on the outer wall. It achieves the effect of forming an air buffer layer on the back of the phone to help dissipate heat, while allowing external devices to be directly connected to the phone interface and allowing users to directly touch the physical buttons, significantly improving the ease of operation and heat dissipation performance.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model embodiment provides a mobile phone case with a multi-functional patch, which aims to solve the problems of existing mobile phone cases having limited functionality, failing to meet magnetic fixation requirements, and having surface decorative patterns easily worn and scratched due to direct contact with the outside environment. Figure 1 and Figure 2 As shown, the phone case with the multi-functional patch includes a transparent rubber phone case 1, and a magnetic ring 5, a magnet 8, and a multi-functional patch 6 that are fixedly connected to the inner wall of the transparent rubber phone case 1 through a structural fit. The transparent rubber phone case 1 serves as the mounting base for the overall structure to protect the phone and support various functional components. The transparent rubber phone case 1 is transparent in shape so that the internal structure and patterns can be displayed from the outside. The transparent rubber phone case 1 is made of thermoplastic polyurethane elastomer material to provide good flexibility and impact resistance.

[0029] Regarding the connection and position of the core components, the inner wall of the transparent rubber phone case 1 has a groove 4, the shape of which matches the shape of the magnetic ring 5. The magnetic ring 5 is embedded and fixedly connected to the inner wall of the groove 4 by adhesive or interference fit. The surface of the magnetic ring 5 is on the same plane as the inner wall surface of the transparent rubber phone case 1 to prevent the magnetic ring 5 from protruding and scratching the back of the phone. The inner wall of the groove 4 provides a stable limiting installation space for the magnetic ring 5. At the same time, the inner wall of the transparent rubber phone case 1 has a fixing groove 7, and a magnet 8 is fixedly connected to the inner wall of the fixing groove 7. The depth of the fixing groove 7 is greater than or equal to the thickness of the magnet 8, so that the magnet 8 can be completely embedded in the fixing groove 7. The magnet 8 is fixed in the fixing groove 7 by interference fit to enhance the overall magnetic attraction force and prevent it from falling off. The magnetic ring 5 and the magnet 8 together constitute the magnetic fixing system of the phone case, so that the phone with the transparent rubber phone case 1 installed can be easily attached to ferrous objects such as car mounts and refrigerator doors.

[0030] Regarding the arrangement of the multi-functional patch 6, the multi-functional patch 6 is adhesively connected to the center of the inner wall of the transparent rubber phone case 1. The multi-functional patch 6 is located on the inner wall surface of the transparent rubber phone case 1 with the patterned side facing the outside of the transparent rubber phone case 1. Due to the transparency of the transparent rubber phone case 1, the user can clearly see the pattern of the multi-functional patch 6 through the transparent rubber phone case 1. This internal design clamps the multi-functional patch 6 between the transparent rubber phone case 1 and the back of the phone, thereby physically isolating the multi-functional patch 6 from contact with the outside world and effectively preventing the pattern from being scratched or falling off due to friction during daily use. In terms of overall layout, the magnetic ring 5 is arranged around the outer periphery of the multi-functional patch 6, and the fixing groove 7 is arranged between the outer periphery of the groove 4 and the edge of the transparent rubber phone case 1. There are multiple fixing grooves 7 and multiple magnets 8 are symmetrically distributed on the inner wall of the transparent rubber phone case 1, thereby forming a stable and uniform magnetic adsorption area around the multi-functional patch 6.

[0031] To solve the above technical problems, a functional slot structure is also provided on the transparent rubber phone case 1, and the outer hollow slot 2 and heat dissipation hole 3 respectively form a specific physical channel and heat dissipation space between the outer wall and the inner wall of the transparent rubber phone case 1.

[0032] Please refer to Figure 1 and Figure 2 The outer wall of the transparent rubber phone case 1 has multiple outer hollow grooves 2, which extend from the outer wall to the inner wall of the transparent rubber phone case 1. The positions of the outer hollow grooves 2 precisely correspond to the positions of the physical buttons and data interface on the side of the phone. The outer hollow grooves 2 form an open window on the side of the transparent rubber phone case 1 by physically removing part of the rubber material. This provides a channel for external devices such as charging cables or headphone plugs to pass directly through the transparent rubber phone case 1 and connect to the phone. At the same time, the outer hollow grooves 2 expose the volume buttons and power button on the side of the phone to the outside, making it convenient for users to directly touch and operate the buttons without pressing through a thick rubber layer, thus ensuring clear and sensitive tactile feedback for button operation.

[0033] Meanwhile, the inner wall of the transparent rubber phone case 1 has multiple heat dissipation holes 3. The heat dissipation holes 3 are evenly distributed on the inner wall surface of the transparent rubber phone case 1. When the phone is installed in the transparent rubber phone case 1, the heat dissipation holes 3 are located between the back of the phone and the inner wall of the transparent rubber phone case 1. The heat dissipation holes 3, as concave micro air cavities, can effectively reduce the direct contact area between the back of the phone and the rubber material. This structural design ensures that when the phone is running for a long time and generates heat, the heat of the inner wall of the transparent rubber phone case 1 can be assisted in conduction and dissipation through the air buffer layer formed by the heat dissipation holes 3, thereby reducing the heat accumulation effect inside the transparent rubber phone case 1 and playing a role in protecting the phone hardware.

[0034] Regarding the specific functional structure of the multi-functional patch 6, it is not merely a decorative layer. It also includes a reflective coating and a fluorescent coating. The reflective coating utilizes the principle of optical reflection to reflect external light back in the dark or in low-light environments, serving as a warning to alert the surrounding environment. The fluorescent coating utilizes the properties of light-emitting materials to emit a soft glow in the dark after absorbing natural light or lamplight energy, making it easier for users to quickly locate and find their phones in the absence of light sources at night. The multi-functional patch 6 is firmly attached to the center of the inner wall of the transparent rubber phone case 1 via an adhesive layer on the back. This method of attachment allows the operator to quickly peel off and replace the multi-functional patch 6 with different patterns or functional focuses as needed, and the replacement process does not require disassembling the complex structure.

[0035] As a preferred embodiment, to ensure the stability and flatness of the magnetic assembly during installation, please refer to... Figure 3 The shape of the groove 4 is adapted to the shape of the magnetic ring 5. The groove 4 is a circular structure to match the outline of the standard circular magnetic ring 5. The magnetic ring 5 is embedded and fixed in the groove 4, and the surface of the magnetic ring 5 is on the same plane as the inner wall surface of the transparent rubber phone case 1. This flush structure design ensures that the magnetic ring 5 can effectively exert its magnetic force while eliminating the protrusions on the inner wall of the transparent rubber phone case 1, thereby preventing the hard magnetic ring 5 from directly pressing against the back glass or metal shell of the phone and effectively preventing scratches on the back of the phone.

[0036] As another preferred embodiment, to further enhance the reliability of magnetic fixation and prevent magnet 8 from falling off, please refer to... Figure 4 The depth of the fixing groove 7 is greater than or equal to the thickness of the magnet 8. The magnet 8 is interference-fitted and fixed in the fixing groove 7. The fixing groove 7 uses the elastic deformation of the rubber material itself to tightly wrap the side wall of the magnet 8, so that the magnet 8 will not easily loosen or fall out during long-term force adsorption. At the same time, the design of the magnet 8 being completely sunk into the fixing groove 7 ensures that the magnet 8 will not protrude from the inner wall plane of the transparent rubber phone case 1, which also plays the role of protecting the back of the phone.

[0037] As a further preferred embodiment, in order to optimize the distribution of the magnetic field to adapt to objects of different sizes and types, the fixing groove 7 is set between the outer periphery of the groove 4 and the edge of the transparent rubber phone case 1. The fixing groove 7 is radially distributed around the center of the groove 4. There are multiple magnets 8, which are symmetrically distributed on the inner wall of the transparent rubber phone case 1. Through the cooperation of the continuous annular magnetic force provided by the magnetic ring 5 in the central area and the point-like reinforcing magnetic force provided by the multiple magnets 8 in the outer area, a composite magnetic array with a wide coverage area and strong adsorption force is constructed, which effectively improves the stability of the transparent rubber phone case 1 adsorbed on ferrous objects such as car brackets or refrigerator doors.

[0038] As another preferred embodiment, in order to ensure the overall protective performance and visual effect of the phone case, the transparent rubber phone case 1 is made of thermoplastic polyurethane elastomer material. The transparent rubber phone case 1 is transparent in all aspects. The thermoplastic polyurethane elastomer material not only gives the transparent rubber phone case 1 excellent drop resistance and shock absorption performance, but its high light transmittance also allows the pattern of the multi-functional patch 6 located on the inner wall to be clearly and realistically displayed to the outside through the transparent rubber phone case 1. The patterned side of the multi-functional patch 6 faces the outer side of the transparent rubber phone case 1, so that the reflective or fluorescent effect of the multi-functional patch 6 can penetrate the transparent rubber phone case 1 and diffuse outward without obstruction.

[0039] Working principle: When the user puts the phone into the inner wall of the transparent rubber phone case 1, the transparent rubber phone case 1 uses the flexibility of thermoplastic polyurethane elastomer material to wrap the phone body to provide protection. Through the open design of the outer hollow groove 2, external devices can pass through the transparent rubber phone case 1 to connect to the phone's data interface or charging interface. At the same time, the outer hollow groove 2 makes the physical buttons on the side of the phone directly exposed, making it easy for the user to directly touch and operate the buttons, avoiding the thick rubber layer blocking the button feel.

[0040] During the process of generating heat during prolonged use of the mobile phone, the hot air between the back of the mobile phone and the transparent rubber mobile phone case 1 can circulate and exchange through the multiple heat dissipation holes 3 opened on the inner wall of the transparent rubber mobile phone case 1. The air buffer layer formed by the heat dissipation holes 3 effectively dissipates the temperature accumulated on the inner wall of the transparent rubber mobile phone case 1, thereby assisting the mobile phone in heat dissipation and reducing the heat accumulation inside the mobile phone case.

[0041] When a user needs to hold their phone in place, the magnetic ring 5 fixed to the inner wall of the groove 4 and the magnet 8 embedded in the fixing groove 7 work together to achieve magnetic adsorption. The groove 4 and the fixing groove 7 firmly restrict the magnetic ring 5 and the magnet 8 to the inner wall of the transparent rubber phone case 1 without protruding from the surface. The phone with the transparent rubber phone case 1 installed can be easily adsorbed onto ferrous objects such as car mounts and refrigerator doors using the composite magnetic field generated by the magnetic ring 5 and the magnet 8. This allows users to hold their phones in different scenarios such as driving navigation or cooking in the kitchen without using their hands.

[0042] Regarding visual display and protective functions, the multi-functional sticker 16 is a self-adhesive sticker with multiple functions such as reflectivity and fluorescence. It is adhered to the center of the inner wall of the transparent rubber phone case 1. Due to the high light transmittance of the transparent rubber phone case 1, external light can penetrate and shine on the reflective or fluorescent coating of the multi-functional sticker 16 to achieve a warning or nighttime glow effect. Moreover, the multi-functional sticker 16 is adhered to the inner wall of the transparent rubber phone case 1 and does not come into direct contact with the outside. This inner-attachment structure avoids the printed pattern on the outer wall from being scratched or falling off due to daily friction, effectively solving the problem of pattern protection. At the same time, it is convenient for the operator to quickly replace the multi-functional sticker 16 with different effects.
