Description

Technical Field

[0001] This application relates to the technical field of mobile phone accessories, and more specifically, to a composite magnetic panel structure. Background Technology

[0002] With the advancement of technology, mobile phones, tablet computers and other smart handheld devices have become indispensable daily necessities in modern life and work. In addition to serving basic needs such as communication and information retrieval, they also provide leisure platforms for watching videos, listening to music or playing games.

[0003] However, since handheld devices are precision electronic products, their structure is more fragile than that of ordinary items. When subjected to violent impacts such as collisions or drops, they are easily damaged, resulting in product failure and unusability. Therefore, it is very common to install shock-resistant protective cases or drop-proof cases on handheld devices to obtain good shockproof effects.

[0004] Furthermore, with the development and maturation of wireless charging technology, it has gradually been applied to electronic products around us, such as mobile phones and tablets, changing the traditional plug-in charging method and improving charging efficiency. Currently, the most common method is to place electronic products on a charging pad. The charging method involves aligning the coils of the electronic product, such as a mobile phone, with the pad to increase charging efficiency.

[0005] However, in order to accommodate the wireless charging module of the aforementioned mobile device, existing protective cases or drop protection cases also have corresponding magnetic coil components. However, since the thickness of the back panel of traditional protective cases affects the magnetic positioning capability, it also affects the convenience of charging. Furthermore, the magnetic coil components of existing protective cases or drop protection cases are glued to the outer shell of the mobile device with adhesive, which also significantly increases the thickness of the protective case or drop protection case.

[0006] At the same time, the design of existing transparent magnetic phone cases on the market is basically to process magnetic grooves for placing magnets on thicker glass. In addition to increasing the weight of the glass itself, the processed glass is prone to hidden scratches, increasing the risk of breakage and resulting in waste of replacements.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0008] In view of this, in order to provide a structure that is different from the prior art and to improve the above-mentioned shortcomings, the applicant has accumulated many years of experience and continuous research and development, resulting in this application.

[0009] One objective of this application is to provide a composite magnetic panel structure that is simple in structure, scratch-resistant, explosion-proof, and can achieve good charging efficiency, which, when combined with a frame, forms a shockproof case for mobile phones.

[0010] To achieve the above objectives, this application provides a composite magnetic panel structure for use with a TPU soft rubber frame, which is then bonded together by injection molding to form a shockproof case for mobile phones. The composite magnetic panel structure includes a bottom layer and an outer layer. The bottom layer is a composite board, and the outer layer is a glass layer that can be attached to the bottom layer. The bottom layer is composed of a PMMA (Polymethylmethacrylate) acrylic sheet and a PC (polycarbonate) sheet, and a magnet is embedded between the PMMA acrylic sheet and the PC sheet.

[0011] In practice, the PC board has a slot for embedding the magnet, and the surface of the slot is coated with ink.

[0012] During implementation, a magnetic ring pattern is printed on the PMMA acrylic plate.

[0013] To facilitate a deeper understanding of this application, a detailed description will be provided in the following embodiments. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one component or feature relative to another component or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, a component described as "below other components or features" or "below other components or features" will subsequently be oriented "above other components or features" or "above other components or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] Please see Figures 1 to 3 This is one embodiment of the composite magnetic panel structure 1 of this application. It is used to form a shockproof case for a mobile phone 3 after being combined with a TPU soft rubber frame 2 by injection molding. The composite magnetic panel structure 1 consists of a bottom layer 11 and an outer layer 12.

[0024] like Figure 1 , 2 As shown, the bottom layer 11 is a composite board, which is made of a PMMA (Polymethylmethacrylate) acrylic sheet 111 and a PC (polycarbonate) sheet 112. A magnet 4 is embedded between the PMMA acrylic sheet 111 and the PC sheet 112. The PC sheet 112 has a groove 113 for the magnet 4 to be embedded in. The surface of the groove 113 is coated with ink. A magnetic ring pattern 114 is printed on the PMMA acrylic sheet 111.

[0025] The outer layer 12 is a glass layer that can be attached to the bottom layer 11.

[0026] Therefore, in implementation, such as Figures 1 to 3 As shown, firstly, the magnet 4 is attached to the slot 113 of the PC board 112, and then the PMMA acrylic board 111 is composited with the PC board 112 to form the bottom layer 11. Finally, the bottom layer 11 is bonded to the outer layer 12 with an adhesive (such as high-transparency UV adhesive) to form the composite magnetic panel structure 1. After being combined with the frame 2 by injection molding, the mobile phone 3 is locked in the frame 2 and protected, so that when the mobile phone 3 is placed on the charging board, it can be aligned with the coil on the charging board for charging.

[0027] Furthermore, the bottom layer 11 and the outer layer 12 in the composite magnetic panel structure 1 of this application can have different designs to match the frame 2. For example, the bottom layer 11 and the outer layer 12 are provided with corresponding holes 110 and 120, so that an aluminum alloy camera decorative ring 5 can be set on the composite magnetic panel structure 1 of this application and combined with the frame 2.

[0028] Therefore, the design of this application has the following advantages:

[0029] 1. The design of the bottom layer of this application uses a composite board to house the magnet. The magnet is protected by the PMMA acrylic board and the PC board. Compared with the traditional structure, the design of the magnet being directly bonded to the glass not only allows for bonding with thinner glass, thus reducing the overall weight of the product, but also avoids causing hidden damage to the middle of the glass and reduces the risk of breakage.

[0030] 2. This application uses thinner glass to bond with composite panels, which can improve the product's toughness, facilitate product assembly and disassembly, and also maintain the overall structural strength, hardness, transparency, and scratch resistance. It can also bond other materials and patterned back panels, increasing product diversity.

[0031] The above description is a specific embodiment of the present application and the technical means used. Many changes and modifications can be derived from the disclosure or teachings herein, which can still be regarded as equivalent changes to the concept of the present application. The effects produced do not exceed the essential spirit covered by the specification and drawings, and should all be regarded as within the technical scope of the present application.

[0032] In conclusion, based on the content disclosed above, this application can indeed achieve the intended purpose of the novel application, providing a composite magnetic panel structure that is highly practical and has industrial value. Therefore, a novel patent application is filed in accordance with the law.
