Description

Technical Field

[0001] This utility model relates to the field of magnetic attracting sheets, specifically, to a magnetic attracting sheet that can be fitted with a hanging rope. Background Technology

[0002] With the widespread use of mobile devices, smartphones have become necessities in people's lives, and various magnetic devices such as magnetic car mounts and magnetic power banks are also popular due to their convenience. These devices connect and hold the phone or its case by attracting magnetic plates, providing convenience for users in different scenarios.

[0003] However, there are significant problems with the connection of existing magnetic sheets to magnetic attraction devices. On the one hand, the magnetic attraction effect is prone to failure. Defects in the material and manufacturing process of the magnetic sheet itself may cause the magnetism to weaken over time. For example, if inferior magnetic materials are used, the internal magnetic domain structure will change, and the magnetism will be greatly reduced. External environmental factors can also interfere. At high temperatures, the magnetic sheet expands and contracts with temperature changes its internal structure, and in humid environments, it is easy to oxidize and form an oxide layer, which hinders the transmission of magnetic lines of force and reduces the magnetic attraction effect.

[0004] On the other hand, vibration can easily cause the phone to fall. In actual use, the phone is often affected by vibration, such as the vibration caused by the bumps of a vehicle or the user tapping the keyboard. This can make the connection between the magnetic sheet and the magnetic device unstable. The weak magnetic force is difficult to maintain the connection under vibration, and the phone is easy to fall off. High-end phones are expensive to repair or even cannot be repaired, causing economic losses and inconvenience to users.

[0005] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

[0054] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a magnetic sheet that can be fitted with a hanging rope.

[0055] Reference Figures 1 to 5 According to an embodiment of the present invention, a magnetic strip for mounting a hanging rope 20 includes a magnetic strip body 10, an extension piece 14, and a hanging part 15.

[0056] The magnetic sheet body 10 has a first surface 11 and a second surface 12. The first surface 11 and the second surface 12 are arranged opposite to each other along the thickness direction of the magnetic sheet body 10. An adhesive piece 13 is provided on the first surface 11 for attaching the magnetic sheet body 10 to the back of a mobile phone or the back of a mobile phone case. The adhesive piece 13 is a double-sided adhesive. The second surface 12 is adapted to be connected to a magnetic attraction device.

[0057] The extension piece 14 is connected to the periphery of the magnetizing sheet body 10 and extends in a direction perpendicular to the thickness direction.

[0058] The hook part 15 is provided on the extension piece 14 and is used to connect the hanging rope 20.

[0059] The lanyard 20 is configured to secure its free end to an external anchor point to prevent the phone from falling if the phone's fixation fails. Advantageously, the lanyard 20 can be used as a safety lanyard when the magnetic plate is not connected to the magnetic attraction device to prevent the phone from falling.

[0060] Based on the above, in use, the magnetic sheet body 10 is attached to the back of the mobile phone or the back of the mobile phone case via the adhesive piece 13. Simultaneously, the second surface 12 can be connected to a magnetic suction device, thus completing the connection and fixation between the mobile phone and the magnetic suction device. The extension piece 14 is provided with a hanging part 15, which can be connected to a lanyard 20, fixing the free end of the lanyard 20 to an external anchor point. When the mobile phone experiences fixation problems due to magnetic failure, the lanyard 20 can provide a pulling effect, effectively preventing the mobile phone from falling and reducing damage caused by falls, thus minimizing economic losses for the user. Integrating the magnetic sheet and lanyard 20 installation functions into one unit eliminates the need for complex modifications to the mobile phone or the addition of other components. It retains the original magnetic suction function of the magnetic sheet while adding the drop-proof function of the lanyard 20, making it convenient and highly practical.

[0061] Preferably, in one embodiment of the present invention, the hook part 15 is integrally formed on the far end of the extension piece 14, the hook part 15 is provided with a raised structure 151 protruding upward from the surface of the extension piece 14, and one end of the hanging rope 20 is fixed on the raised structure 151.

[0062] Thus, since the hook part 15 is integrally formed at the far end of the extension piece 14, this integral design eliminates the need for additional connecting structures between the hook part 15 and the extension piece 14. The overall structure is more compact and stable, reducing the possibility of the lanyard 20 being affected by loosening or falling off of the connecting parts, thereby improving the reliability and durability of the product. The hook part 15 is provided with a raised structure 151 that protrudes upward from the surface of the extension piece 14, which facilitates the fixing of one end of the lanyard 20 to the raised structure 151 without interfering with the fixing of the magnetic sheet and the mobile phone.

[0063] It is understood that since the raised structure 151 protrudes upward from the surface of the extension piece 14, a certain space can be formed between the bottom surface of the raised structure 151 and the back of the mobile phone or the back of the mobile phone case, so as to avoid interference between the installation of the lanyard 20 and the fixing of the magnetic sheet to the back of the mobile phone or the back of the mobile phone case.

[0064] Preferably, in one embodiment of the present invention, one end of the raised structure 151 extends to the distal end face of the extension piece 14, thereby defining a guide rope gap G between the raised structure 151 and the back of the mobile phone or the back of the mobile phone case, extending to the distal end face of the extension piece 14.

[0065] The raised structure 151 is provided with a connecting hole 152. One end of the hanging rope 20 is fixed in the connecting hole 152 and extends from the guide rope gap G to the outside of the end face of the extension piece 14.

[0066] Thus, since one end of the raised structure 151 extends to the distal end face of the extension piece 14 to form a guide rope gap G, when the hanging rope 20 and the connecting hole 152 are connected, it can be led out along the guide rope gap G, thereby avoiding interference between the hanging rope 20 and the magnetic sheet and the mobile phone. This facilitates the installation of the hanging rope 20 and ensures the stability of the magnetic sheet installation.

[0067] like Figure 7 As shown, in one embodiment of the present invention, the raised structure 151 extends along the width direction of the extension piece 14, and the raised structure 151 is provided with a connecting hole 152. There are one or more connecting holes 152. When there are multiple connecting holes 152, the multiple connecting holes 152 are distributed at intervals along the width direction of the extension piece 14, and one end of the hanging rope 20 is fixed in the connecting hole 152.

[0068] Thus, the raised structure 151 extends along the width direction of the extension piece 14, and one or more connecting holes 152 can be provided. When multiple connecting holes 152 are provided, they are distributed at intervals along the width direction of the extension piece 14. The design of multiple connecting holes 152 can distribute the pulling force of the lanyard 20 on the magnetic plate. When the mobile phone is pulled by an external force, the pulling force of the lanyard 20 will be evenly transmitted to the magnetic plate through multiple connecting holes 152, avoiding loosening or damage caused by excessive pulling force on a single connecting hole 152, and also making the connection of the lanyard 20 more convenient and stable.

[0069] like Figure 6As shown, in one embodiment of the present invention, the raised structure 151 extends along the length direction of the extension piece 14, and the raised structure 151 is provided with a connecting hole 152. There are one or more connecting holes 152. When there are multiple connecting holes 152, the multiple connecting holes 152 are distributed at intervals along the length direction of the extension piece 14, and one end of the hanging rope 20 is fixed in the connecting hole 152.

[0070] Thus, the raised structure 151 extends along the length of the extension piece 14, and one or more connecting holes 152 can be provided, allowing for appropriate processing selection according to actual needs. When there are multiple connecting holes 152, they are distributed at intervals along the length of the extension piece 14, which can effectively disperse the pulling force of the lanyard 20 on the magnetic sheet. When the mobile phone is accidentally dropped or pulled by an external force, the pulling force will be evenly transmitted to the magnetic sheet through multiple connecting holes 152, avoiding the loosening or damage of a single connecting hole 152 due to excessive pressure. This greatly enhances the stability of the lanyard 20, ensuring that the mobile phone can be reliably prevented from falling when the mobile phone fixation fails, thus protecting the mobile phone's safety.

[0071] like Figure 8 As shown, in one embodiment of the present invention, the hook part 15 is ring-shaped, one end of the hook part 15 is pivotally connected to the distal end of the extension piece 14, and one end of the hanging rope 20 is fixed on the hook part 15.

[0072] The distal end of the extension piece 14 is curled to form a hook hole 141. One end of the hook part 15 passes through the hook hole 141 and can rotate along the axis of the hook hole 141.

[0073] Thus, by curling the distal end of the extension piece 14 to form a hook hole 141, one end of the hook part 15 passes through it, resulting in a simple and stable structure. The curled distal end of the extension piece 14 provides reliable support and rotation space for the hook part 15, while reducing additional connecting parts, lowering structural complexity and failure risk, and improving product reliability and durability. The ring-shaped hook part 15 facilitates the connection and removal of the hanging rope 20.

[0074] Preferably, in one embodiment of the present invention, the magnetic sheet body 10 is made of ultra-thin manganese steel or stainless iron, and a decorative layer 16 is provided on the surface of the magnetic sheet body 10 and the surface of the extension sheet 14. The decorative layer 16 is a film material and is pasted on the surface of the magnetic sheet body 10 and the extension sheet 14.

[0075] Understandably, the lightweight and thin profile of ultra-thin manganese steel minimizes the burden on the phone, ensuring its portability and allowing users to use it anytime, anywhere, without discomfort whether in a pocket, backpack, or hand. Manganese steel itself possesses high strength and good toughness; the ultra-thin manganese steel material, while maintaining its slim profile, still provides sufficient structural strength for the magnetic sheet body 10, making it less prone to deformation or damage under external pressure or impact, thus extending the lifespan of the magnetic sheet.

[0076] Stainless iron is a relatively low-cost material, which can reduce production costs while maintaining certain performance, thus making the product more price-competitive in the market and more affordable for consumers. Furthermore, stainless iron has excellent rust-resistant properties, effectively resisting corrosion from environmental factors such as air and moisture, and is not prone to rusting. This ensures the stability of the appearance and performance of the magnetic sheet body 10 during long-term use, reducing functional failures and cosmetic damage caused by rust.

[0077] Meanwhile, both the surface of the magnetic strip body 10 and the surface of the extension piece 14 are provided with decorative layers 16. These layers can be decorated with various colors, patterns, or textures according to different design needs and user preferences, transforming the magnetic strip from a monotonous functional accessory into a highlight of the phone's appearance, enhancing its overall aesthetics and style. The diversity of the decorative layers 16 provides users with space for personalized customization. Users can choose magnetic strips with different decorative effects according to their own style and preferences, making the phone more personalized and satisfying different users' pursuit of product personalization.

[0078] Preferably, in one embodiment of the present invention, the magnetic sheet body 10 is annular, with an outer diameter of 50-65 mm and an inner diameter of 40-49 mm.

[0079] Thus, the outer diameter of the magnetic sheet body 10 is set within the range of 50-65mm, and the inner diameter within the range of 40-49mm. This size range can accommodate most common-sized mobile phones on the market. Whether it's a small, slim phone or a large flagship model, the magnetic sheet can fit the phone well, without affecting the usability due to being too large or too small. This greatly improves the product's versatility and reduces the inconvenience caused by incompatible phone sizes. Furthermore, based on purchasing various types of magnetic devices on the market, performance is improved by 20% within this size range.

[0080] Meanwhile, the ring-shaped design and suitable size range make this magnetic plate compatible with various types of magnetic accessories. For example, it can stably connect with accessories such as magnetic phone holders, magnetic car chargers, and magnetic wireless power banks, meeting users' needs for phone fixation and charging in different scenarios and providing users with more usage options and convenience.

[0081] Preferably, according to one embodiment of the present invention, the distance between the hook part 15 and the center of the outer side of the magnetic sheet body 10 is greater than 35mm.

[0082] Thus, by ensuring that the center distance between the hook part 15 and the outer side of the magnetic plate body 10 is greater than 35mm, the lanyard 20, after being connected to the hook part 15, will not be too close to the magnetic device, and will not affect the rotational adjustment between the magnetic device and the magnetic plate body 10. Based on purchasing various types of magnetic devices on the market, performance is improved by 20% within this size range.

[0083] Preferably, in another embodiment of this utility model, the plane height of the hanging part 15 is 1-3.5mm. Based on the characteristic that the closer the wireless charging device and the device being charged are, the higher the charging efficiency, this design satisfies both the need for the lanyard 20 to be installed through the hole and ensures the height setting of some magnetic devices during charging.
