Description
Expandable phone holder Technical Field
[0001] This invention relates to mobile phone accessories, and more particularly to an expandable mobile phone stand. Background Technology
[0002] An expandable phone holder is a phone accessory configured to attach to the back of a phone / phone case (via adhesive or "MagSafe" magnetic attachment) to enhance the user's grip on the phone and prevent it from slipping or falling due to impact. Expandable phone holders can switch between an "expanded" and "folded" state for convenient storage and portability. Nevertheless, there is still room for improvement in existing expandable phone holders.
[0003] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention
[0004] The main objective of this invention is to overcome the deficiencies in the aforementioned background technology and provide an expandable mobile phone holder.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An expandable phone holder includes:
[0007] A base assembly configured to be attached to a mobile phone or a phone case, the base assembly having an opening at its edge such that the planar cross-section of the base assembly is concave;
[0008] Top component, used to provide a grippy part;
[0009] A foldable shell, the foldable shell being based on an airbag structure, one end of the foldable shell being connected to the base assembly, and the other end of the foldable shell being connected to the top assembly, the foldable shell being used to realize the folding and expansion between the base assembly and the top assembly;
[0010] An attachment for attaching the expandable phone holder to the phone or the phone case.
[0011] Furthermore, the airbag structure of the foldable shell is a hollow cone structure with a gradually decreasing dimension toward the top component.
[0012] Furthermore, the attachment is an adhesive component.
[0013] Furthermore, the attachment is a magnet, which is disposed within the base assembly and configured to attract the mobile phone or the mobile phone case.
[0014] Furthermore, the magnet enables the expandable phone holder to exert a peel force of 20N or more on the phone or the phone case.
[0015] Furthermore, the magnet is selected as an N54 grade neodymium iron boron magnet with a size of 2.7±0.8 mm and a Gauss strength range of 4700-4800 GS.
[0016] Furthermore, the opening is a "C"-shaped opening formed at the edge of the base assembly.
[0017] Furthermore, the top assembly includes a top base and a top cover. The top base is disposed between the foldable housing and the top cover. A connecting portion is provided on the lower side of the top cover. The top base is provided with a through hole. The connecting portion of the top cover is connected to the top end of the foldable housing through the through hole.
[0018] Furthermore, the top cover is configured to be snap-fitted to the top base, thereby allowing the top cover to be printed with an image on the inside before being assembled onto the top base.
[0019] The present invention has the following beneficial effects:
[0020] This invention proposes an expandable phone holder. Through an opening design at the edge of the base assembly, the planar cross-section of the base assembly is concave. When the base assembly is connected to a phone or phone case, the opening position can accommodate the user's fingers (e.g., index, middle, and / or ring fingers) gripping the expandable phone holder, reducing discomfort to the user's fingers caused by protrusions at the edge of the base assembly, and is more ergonomic. Furthermore, for phones with multiple lenses, or where lens components (including the lens itself and / or flash) cover a relatively large area of the phone, the opening direction of the base assembly can be configured to expose the phone lens, flash, and / or the lens frame of the phone case, effectively avoiding obstruction of these components. Further, a magnet is used as an attachment element, configured to achieve a magnetic peel force of over 15N. Through comprehensive optimization and synergy with the opening design, ease of use and compatibility are improved while ensuring the stability of the phone holder's adhesion to the phone / phone case. Furthermore, the foldable shell design based on a "positive" cone-shaped airbag structure naturally isolates the grip area from the back of the phone, conforming to the physiological curvature of the palm and back of the hand, significantly reducing hand fatigue during prolonged use. Moreover, the modular assembly structure design of the bottom shell, bottom inner shell, and foldable shell achieves high-strength connections and a compact layout between components, balancing portability and durability. In addition, the snap-on top cover design of the top component supports personalized image printing, further facilitating the expansion of the product's aesthetic value and user interaction experience.
[0021] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

[0039] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.
[0040] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to that other component. Furthermore, a connection can be used for fixing, coupling, or communication.
[0041] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and 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 the present invention.
[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0043] Referring to Figures 1 to 5, an embodiment of the present invention provides an expandable mobile phone stand, including a base assembly, an attachment, a foldable shell 4, and a top assembly.
[0044] The base assembly is configured to attach to a mobile phone or phone case, and the base assembly has an opening at its edge to make its planar cross-section concave. According to one embodiment, a portion of the edge of the base assembly is cut out to make the outer periphery of the edge arc-shaped, with openings at both ends of the arc. In a preferred embodiment, the opening is a "C"-shaped opening formed at the edge of the base assembly.
[0045] While every user grips an expandable phone holder differently, a common method is to insert it between two adjacent fingers (e.g., between the index and middle fingers, or between the middle and ring fingers). Compared to existing expandable phone holders, which typically feature a fully circular base assembly with a ring magnet, the protruding edges of this circular base assembly can cause discomfort to the user's fingers when using existing expandable phone holders.
[0046] Conversely, as shown in Figure 9, when the base assembly of the expandable phone holder of this embodiment is connected to a phone or phone case, the opening is positioned to accommodate the user's fingers (e.g., index, middle, and / or ring fingers) gripping the expandable phone holder, reducing discomfort to the user's fingers caused by protrusions at the edges of the base assembly, and is more ergonomic. Specifically, the opening of the base assembly can be configured to face the direction of the user's dominant hand gripping the phone (e.g., right hand), allowing the user's fingers (e.g., index, middle, and / or ring fingers) to be accommodated in the opening.
[0047] In addition, for mobile phones with multiple lenses, or for situations where lens components (including the lens itself and / or flash) cover a relatively large area of the phone, as shown in Figure 10, previous expandable phone holders used a complete circular structure on the base assembly that attaches to the phone or phone case and set a ring magnet. When the user uses the expandable phone holder, the edge of the circular base can easily block the phone lens or the lens frame of the phone case.
[0048] To address the aforementioned shortcomings, the expandable phone holder of this invention can be configured to expose the phone lens, flash, and / or the lens frame of the phone case, thereby avoiding obstruction of the phone lens, flash, and / or the lens frame of the phone case, as shown in Figure 11.
[0049] The attachment is used to attach an expandable phone holder to a phone or phone case. The attachment may be a magnet 7, disposed within the base assembly and configured to attract the phone or phone case. The attachment may also be an adhesive (such as an adhesive) or other connection method.
[0050] According to one embodiment, the magnet 7 is disposed within the base assembly having the opening for adsorbing a mobile phone or phone case, and the peel force between the expandable phone holder and the mobile phone or phone case is 15N or more; preferably, the peel force is 17N or more; more preferably, the peel force is 20N or more. This configuration is sufficient to adsorb a mobile phone or phone case.
[0051] The foldable outer shell 4, based on an airbag structure, is connected to the base assembly and enables folding and expansion between the base assembly and the top assembly, facilitating carrying and storage. The top assembly, connected to the foldable outer shell 4, provides a gripping portion for the expandable phone holder. Through the above comprehensive optimization design, on the one hand, when the base assembly is attached to a phone or phone case, the opening design at the edge precisely avoids the phone lens or the lens frame of the phone case, ensuring that the shooting function is not affected, while improving the compatibility of the holder with different phone models; on the other hand, the magnet 7 is configured to ensure that the peel force between the holder and the phone or phone case reaches more than 20N, providing a stable adsorption effect, preventing the holder from accidentally falling off, and meeting the needs of high-intensity use.
[0052] In some embodiments, the magnet 7 is an N54 grade neodymium iron boron magnet with a size of 2.7 ± 0.8 mm and a Gaussian strength range of 4700-4800 (+ / - 150) GS. Furthermore, the magnet 7 has a nickel-copper plating layer with a thickness of approximately 8-10 micrometers. This preferred design ensures that the magnet 7 has sufficient magnetic attraction force, guaranteeing a peel force of over 20N between the expandable phone holder and the phone or phone case.
[0053] In a preferred embodiment, the airbag structure of the foldable housing 4 is a hollow cone structure with a gradually decreasing size towards the top component. Through this design, the airbag portion of the foldable housing 4 is a "positive" cone structure. Compared to the traditional "inverted" cone shown in Figure 12, the "positive" cone airbag provides some isolation between the finger grip position and the back of the phone / phone case, and can arch according to the natural curvature of the palm and back of the hand to avoid prolonged hand extension, thereby reducing hand fatigue, as shown in Figure 9.
[0054] In a preferred embodiment, the base assembly includes a bottom outer shell 3 and a bottom inner shell 5. The bottom outer shell 3 is annular, with an opening formed at its edge. A foldable outer shell 4 is disposed within the annular space of the bottom outer shell 3, with its bottom edge sandwiched between the bottom outer shell 3 and the bottom inner shell 5. A protrusion is provided on the lower side of the bottom outer shell 3, passing through corresponding mounting holes at the bottom edges of the foldable outer shell 4 and the bottom inner shell 5 and being fixed (e.g., welded), thereby fixing the bottom outer shell 3, the foldable outer shell 4, and the bottom inner shell 5 together. Through this design, the bottom outer shell 3, the foldable outer shell 4, and the bottom inner shell 5 are tightly fixed by the cooperation of the protrusion and the mounting holes, ensuring the stability of the connection between the components and the overall structural integrity. This modular assembly method not only simplifies the production process but also enhances the durability and impact resistance of the support. Meanwhile, the bottom edge of the folding outer shell 4 is clamped between the bottom outer shell 3 and the bottom inner shell 5, forming a stable support structure, effectively dispersing external pressure, and preventing the folding outer shell 4 from loosening or deforming during use, thereby ensuring the reliability and service life of the bracket in the folded and extended states.
[0055] In a preferred embodiment, the opening is a "C"-shaped opening formed at the edge of the bottom housing 3. The magnet 7 is mounted at the edge of the bottom housing 3 and conformally engages with the portion of the bottom housing 3 except for the "C"-shaped opening, providing the phone holder with an attractive force for the phone or phone case.
[0056] In a preferred embodiment, the bottom outer shell 3 has a magnet receiving space on its bottom outer side; a flexible material 6 is placed inside the magnet receiving space; the magnet 7 is disposed within the magnet receiving space; and a bottom membrane cover 8 is provided on the outer side of the magnet 7. In some embodiments, the flexible material 6 is an EVA gasket. By placing a flexible material (such as an EVA gasket) inside the magnet receiving space and providing a bottom membrane cover on the outer side, direct contact between the magnet and the external environment is effectively buffered, preventing damage to the magnet due to vibration or collision, while ensuring the uniform distribution and stability of the magnetic attraction force.
[0057] In a preferred embodiment, the top assembly includes a top base 2 and a top cover 1. The top base 2 is disposed between the folding outer shell 4 and the top cover 1. The bottom side of the top cover 1 has a connecting portion, and the top base 2 has a through hole 10. The connecting portion of the top cover 1 is connected to the top end of the folding outer shell 4 through the through hole. Preferably, the top cover 1 is connected to the top base 2 by a snap-fit 11. Thus, without the need for special tools, the mating relationship between the top base and the top cover 1 allows the top cover 1 to be printed with a pattern on its inner side before being assembled onto the top base 2. Through the modular connection design of the top base and the top cover, the top assembly can be quickly assembled and disassembled, facilitating personalized customization (such as printing patterns on the inner side of the top cover). At the same time, it ensures the stability of the connection between the top assembly and the folding outer shell, improving the reliability and aesthetics of the overall structure.
[0058] In another embodiment, as shown in FIG6, the top component may also take other forms, such as the form of a ring holder, that is, the top component is replaced by a ring holder including the ring body 12.
[0059] In another embodiment, as shown in FIG7, the airbag structure of the foldable shell may have a spring 13 in the inner cavity, one end of the spring 13 may be connected to the airbag and the other end may be connected to the top component.
[0060] In addition, as shown in Figure 8, a "fidget spinner" design can also be adopted, in which the entire top cover rotates or the top component is equipped with an additional rotating part 14, which can be equipped with a built-in ball bearing 15 to achieve rotation, combining playfulness and practical function.
[0061] The following describes specific embodiments of the present invention.
[0062] An expandable phone holder includes a base assembly comprising a bottom outer shell 3 and a bottom inner shell 5. The bottom outer shell 3 has a ring-shaped structure with a "C"-shaped opening at its edge. This ensures that when the base assembly is connected to a phone or phone case, the opening is positioned to accommodate the user's fingers (e.g., index, middle, and / or ring fingers) gripping the expandable phone holder, reducing discomfort to the user's fingers caused by protrusions at the edge of the base assembly and improving ergonomics. Furthermore, when the holder is connected to a phone or phone case, the opening precisely avoids obstructing the phone's lens, flash, and / or the lens frame of the phone case, preventing obstruction of shooting functions and improving compatibility with different phone models.
[0063] Magnet 7 is an N54 grade neodymium iron boron magnet with a size of 2.7±0.8 mm and a Gauss strength range of 4700-4800 (+ / -150) GS. It has an 8-10 micrometer thick nickel-copper plating layer to ensure that magnet 7 has sufficient magnetic attraction force, so that the peel force between the bracket and the mobile phone or mobile phone case reaches more than 20N, providing a stable adsorption effect and preventing accidental drop. Magnet 7 is set in the magnet receiving space of the bottom shell 3. The space is padded with a flexible EVA gasket 6, and the outside is equipped with a bottom membrane cover 8, which effectively buffers the direct contact between the magnet and the external environment, prevents the magnet from being damaged by vibration or impact, and ensures the uniform distribution and stability of the magnetic attraction force.
[0064] The folding housing 4 is based on an airbag structure and adopts a "positive" cone design with a gradually decreasing size towards the top component. Compared with the traditional "inverted" cone, the "positive" cone airbag naturally isolates the finger grip position from the back of the phone / phone case and can arch according to the natural curvature of the palm and back of the hand, avoiding prolonged hand extension and significantly reducing hand fatigue. The bottom edge of the folding housing 4 is clamped between the bottom outer shell 3 and the bottom inner shell 5. The bottom outer shell 3 has a protrusion on its lower side, which passes through the mounting hole of the bottom edge of the folding housing 4 and the bottom inner shell 5 and is fixed (such as by welding), forming a stable support structure. This ensures the stability of the connection between the components and the integrity of the structure, effectively disperses external pressure, and prevents the folding housing 4 from loosening or deforming during use, thereby ensuring the reliability and service life of the bracket in the folded and extended states.
[0065] The top assembly includes a top base 2 and a top cover 1. The top base 2 is positioned between the folding outer shell 4 and the top cover 1. The bottom of the top cover 1 has a connecting part, which connects to the top of the folding outer shell 4 through a through hole 10 in the top base 2. The top cover 1 is connected to the top base 2 by a snap-fit 11, facilitating assembly and disassembly without special tools. It also supports printing personalized patterns on the inside of the top cover 1, enhancing the product's aesthetics and user experience.
[0066] In summary, the expandable phone holder of the present invention has achieved significant optimizations in terms of ergonomic design, avoiding lens component obstruction, maintaining stable magnetic attraction, and improving structural reliability. It solves the pain points of the prior art and provides users with a more convenient, comfortable and durable user experience.
