[0001] The present invention relates to mobile phone accessories, and in particular to an expandable mobile phone stand. Background Art

[0002] An expandable mobile phone stand is a mobile phone accessory configured to be connected to the back of a mobile phone / mobile phone case (connected by an adhesive or a "MagSafe" magnetic attachment) to enhance the user's grip on the mobile phone and prevent the mobile phone from dropping due to slippery hands or collisions. The expandable mobile phone stand can be switched between an "expanded" state and a "folded" state, facilitating storage and carrying. Nevertheless, there is still room for improvement in existing expandable mobile phone stands.

[0003] It should be noted that the information disclosed in the above background art section is only for understanding the background of the present application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0004] The main purpose of the present invention is to overcome the defects in the above background art and provide an expandable mobile phone stand.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An expandable mobile phone stand, comprising:

[0007] A base assembly configured to be connectable to a mobile phone or a mobile phone case, the base assembly forming an opening at an edge such that a planar cross-section of the base assembly is concave;

[0008] A top assembly for providing a grippable portion;

[0009] A foldable housing based on an airbag structure, one end of the foldable housing being connected to the base assembly and the other end of the foldable housing being connected to the top assembly, the foldable housing being used to achieve folding and expansion between the base assembly and the top assembly;

[0010] An attachment for engaging the expandable mobile phone stand to the mobile phone or the mobile phone case.

[0011] Further, the airbag structure of the foldable housing is a hollow cone structure that tapers in size towards the top assembly.

[0012] Further, the attachment is an adhesive.

[0013] Further, the attachment is a magnet disposed within the base assembly and configured to

[0014] Adsorb the mobile phone or the mobile phone case.

[0015] Furthermore, the magnet enables the peel force between the expandable mobile phone stand and the mobile phone or the mobile phone case to be 20 N or more.

[0016] Furthermore, the magnet is selected as an N54 grade neodymium iron boron magnet, with a size of 2.7 ± 0.8 mm and a Gaussian intensity range of 4700 - 4800 GS.

[0017] Furthermore, the opening is a "C" - shaped opening formed at the edge of the base assembly.

[0018] Furthermore, the top assembly includes a top base and a top cover. The top base is disposed between the folding 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, and the connecting portion of the top cover is connected to the top end of the folding housing through the through - hole.

[0019] Furthermore, the top cover is arranged to be connected to the top base in a snap - fit manner, so as to allow the top cover to be assembled to the top base after printing an image on the inner side.

[0020] The present invention has the following beneficial effects:

[0021] The present invention provides an expandable mobile phone stand. Through the 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 mobile phone or a mobile phone case, the position of the opening can accommodate the fingers (such as the index finger, middle finger, and / or ring finger) of the user grasping the expandable mobile phone stand, reducing the discomfort of the user's fingers caused by the protrusion of the edge of the base assembly, and being more ergonomic. Additionally, for mobile phones with multiple lenses, or in the case where the lens components (including the lens itself and / or the flash) cover a relatively large area of the mobile phone, the direction of the opening of the base assembly can be configured to expose the mobile phone lens, flash, and / or the lens frame of the mobile phone case, effectively avoiding blocking the mobile phone lens, flash, and / or the lens frame of the mobile phone case. Furthermore, a magnet is used as an attachment, and after configuration, the magnetic peel force reaches more than 15 N. Through comprehensive optimization and in coordination with the opening design, while improving the usability and compatibility, the adsorption stability between the mobile phone stand and the mobile phone / mobile phone case is ensured. Further, based on the "positive" conical airbag structure of the folding housing design, the grasping area forms a natural isolation from the back of the mobile phone, conforming to the physiological curvature of the palm and the back of the hand, significantly reducing the hand fatigue during long - term use. Further, through the modular assembly structure design of the bottom housing, the bottom inner housing, and the folding housing, high - strength connection and compact layout between components are achieved, taking into account portability and durability. In addition, the snap - fit top cover design of the top assembly supports personalized image printing, further facilitating the expansion of the aesthetic value of the product and the user interaction experience.

[0040] The following provides a detailed description of the implementation manners of the present invention. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0041] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be for a fixing function or for a coupling or communication function.

[0042] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present invention.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first"

[0044] "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0045] Referring to Figure 1 FIGs. 4 to 5, an embodiment of the present invention provides an expandable mobile phone stand, which includes a base assembly, an attachment member, a foldable housing 4, and a top assembly.

[0046] The base assembly is configured to be connectable to a mobile phone or a mobile phone case. The base assembly forms an opening at the edge, so that the planar cross-section of the base assembly is concave. According to one embodiment, a part of the edge of the base assembly is hollowed out, so that the periphery of the edge is arc-shaped, and openings are formed 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.

[0047] Although the way each user holds the expandable phone holder varies, a common way is to insert the expandable phone holder between two adjacent fingers (e.g., between the index finger and the middle finger, or between the middle finger and the ring finger). Compared with existing expandable phone holders, their base components that adsorb to the phone or phone case generally adopt a complete circular structure and are provided with annular magnets. When a user uses an existing expandable phone holder, the edge of the base component with a complete circular structure is prone to cause discomfort to the user's fingers due to protrusions.

[0048] In contrast, as Figure 9 shown, when the base component of the expandable phone holder according to an embodiment of the present invention is connected to a phone or phone case, the position of the opening can accommodate the fingers (e.g., index finger, middle finger, and / or ring finger) of the user holding the expandable phone holder, reducing the discomfort of the user's fingers caused by the protrusions of the edge of the base component, which is more ergonomic. Specifically, the direction of the opening of the base component can be configured to face the direction of the user's dominant hand (e.g., the right hand) for holding the phone, so that the user's fingers (e.g., index finger, middle finger, and / or ring finger) are accommodated at the position of the opening.

[0049] In addition, for a phone with multiple lenses, or in the case where the lens component (including the lens itself and / or the flash) covers a relatively large area of the phone, as Figure 10 shown, existing expandable phone holders adopt a complete circular structure on the base component that adsorbs to the phone or phone case and are provided with annular magnets. When a user uses an expandable phone holder, it is easy for the edge part of the circular base to block the phone lens or the lens frame of the phone case.

[0050] To address the above-mentioned defects, the expandable phone holder according to an embodiment of the present invention can configure the direction of the opening of the base component to expose the phone lens, flash, and / or the lens frame of the phone case, avoiding blocking the phone lens, flash, and / or the lens frame of the phone case, as Figure 11 shown.

[0051] The attachment is used to engage the expandable phone holder to the phone or phone case. The attachment can

[0052] be a magnet 7, which is disposed inside the base component and is configured to adsorb the phone or phone case. The attachment can also be other connection means such as an adhesive.

[0053] According to one embodiment, the magnet 7 is disposed inside the base component having the opening, for adsorbing the phone or phone case, and making the peeling force between the expandable phone holder and the phone or phone case be above 15 N; preferably, the peeling force is above 17 N; more preferably, the peeling force is above 20 N. It is configured to be sufficient to adsorb the phone or phone case.

[0054] The foldable housing 4 is based on an airbag structure and is connected to the base assembly, and is used to implement the folding and expanding functions between the base assembly and the top assembly, which is convenient for carrying and storing. The top assembly is connected to the foldable housing 4 and is used to provide the part of the expandable mobile phone stand that can be grasped by the user. Through the above comprehensive optimization design, on the one hand, when the base assembly is connected to the mobile phone or the mobile phone case, the opening design at the edge accurately avoids the mobile phone lens or the lens frame of the mobile phone case, ensuring that the shooting function is not affected, and at the same time improving the compatibility of the stand with different mobile phone models; on the other hand, the magnet 7 is configured to ensure that the peeling force between the stand and the mobile phone or the mobile phone case reaches more than 20 N, providing a stable adsorption effect and preventing the stand from falling off accidentally, meeting the high-strength use requirements.

[0055] In some embodiments, the magnet 7 is a N54 grade neodymium iron boron magnet with a size of 2.7 ± 0.8 mm and a Gauss intensity range of 4700 - 4800 (+ / -150) GS. In addition, the magnet 7 is provided with a nickel-copper coating with a coating thickness of about 8 - 10 microns. The above preferred design enables the magnet 7 to have sufficient magnetic attraction to ensure that the peeling force between the expandable mobile phone stand and the mobile phone or the mobile phone case reaches more than 20 N.

[0056] In a preferred embodiment, the airbag structure of the foldable housing 4 is a hollow cone structure with a gradually decreasing size in the direction towards the top assembly. Through the above design, the airbag part of the foldable housing 4 is a "positive" cone structure. Compared with the traditional "inverted" cone as shown in Figure 12 the "positive" cone-shaped airbag isolates the finger grasping position from the back of the mobile phone / mobile phone case to a certain extent and can arch according to the natural curvature of the human palm and the back of the hand to avoid the palm being straightened for a long time, thereby reducing the hand fatigue, as shown in Figure 9 shown.

[0057] In a preferred embodiment, the base assembly includes a bottom housing 3 and a bottom inner housing 5. The bottom housing 3 is annular, and the opening is formed at the edge of the bottom housing 3. The foldable housing 4 is disposed in the annular space of the bottom housing 3. The bottom edge of the foldable housing 4 is clamped between the bottom housing 3 and the bottom inner housing 5. A protrusion is provided on the lower side of the bottom housing 3, and the protrusion passes through the bottom edge of the foldable housing 4 and the

[0058] The corresponding assembly holes at the edge of the bottom inner shell 5 are pierced and fixed (for example, welded) to fix the bottom outer shell 3, the foldable outer shell 4 and the bottom inner shell 5 together. Through the above design, the bottom outer shell 3, the foldable outer shell 4 and the bottom inner shell 5 are tightly fixed through the cooperation of the protrusions and the assembly holes, ensuring the connection stability and structural integrity between the components. This modular assembly method not only simplifies the production process, but also enhances the durability and impact resistance of the bracket. At the same time, the bottom edge of the foldable outer shell 4 is clamped between the bottom outer shell 3 and the bottom inner shell 5 to form a stable support structure, effectively disperse the external pressure, and prevent the foldable outer shell 4 from loosening or deforming during use, thereby ensuring the reliability and service life of the bracket in the folded and expanded state.

[0059] In a preferred embodiment, the opening is a "C"-shaped opening formed at the edge of the bottom housing 3. The magnet 7 is installed at the edge of the bottom housing 3 and conforms to the portion of the bottom housing 3 except the "C"-shaped opening to provide the mobile phone holder with an adsorption force on the mobile phone or mobile phone case.

[0060] In a preferred embodiment, a magnet accommodating space is provided on the outer side of the bottom of the bottom shell 3; a flexible material 6 is padded in the magnet 7 accommodating space; the magnet 7 is arranged in the magnet accommodating space; and a bottom film cover 8 is provided on the outer side of the magnet 7. In some embodiments, the flexible material 6 is an EVA gasket. By padding the magnet accommodating space with a flexible material (such as an EVA gasket) and providing a bottom film cover on the outer side, the direct contact between the magnet and the external environment is effectively buffered, the magnet is prevented from being damaged by vibration or collision, and the uniform distribution and stability of the magnetic attraction are ensured.

[0061] In a preferred embodiment, the top assembly includes a top base 2 and a top cover 1, wherein the top base 2 is arranged between the foldable housing 4 and the top cover 1, a connecting portion is arranged on the lower side of the top cover 1, and the top base 2 is provided with a through hole 10, through which the connecting portion of the top cover 1 is connected to the top end of the foldable housing 4. Preferably, the top cover 1 is arranged to be connected to the top base 2 in a snap-fit ​​manner 11, so that, without the need for special tools, the matching relationship between the top base and the top cover 1 allows the top cover 1 to be assembled onto the top base 2 after a pattern is printed on the inside. Through the modular connection design of the top base and the top cover, the top assembly can be quickly assembled and disassembled, which is convenient for personalized customization (such as printing a pattern on the inside of the top cover), while ensuring the stability of the connection between the top assembly and the foldable housing, and improving the reliability and aesthetics of the overall structure.

[0062] In another embodiment, if Figure 6As shown, the top component may also be in other forms, such as a finger ring stand, that is, the top component is replaced by the finger ring stand including the finger ring body 12 .

[0063] In another embodiment, Figure 7 As shown, the airbag structure of the foldable shell can be

[0064] A spring 13 is provided in the cavity, one end of the spring 13 can be connected to the airbag, and the other end of the spring 13 can be connected to the top component.

[0065] In addition, if Figure 8 As shown, a "fingertip gyroscope" design may also be adopted, that is, the entire top cover rotates or an additional rotating component 14 is provided on the top assembly, and a ball bearing 15 may be built in to realize rotation, thereby combining the fun of playing with practical functions.

[0066] The specific embodiments of the present invention are further described below.

[0067] An expandable mobile phone holder, whose base assembly includes a bottom outer shell 3 and a bottom inner shell 5, wherein the bottom outer shell 3 is an annular structure with a "C"-shaped opening formed at the edge, ensuring that when the base assembly is connected to a mobile phone or a mobile phone case, the position of the opening can accommodate the user's fingers (such as the index finger, middle finger and / or ring finger) for grasping the expandable mobile phone holder, reducing the discomfort of the user's fingers caused by the protrusions on the edge of the base assembly, and being more ergonomic. Further, when the holder is connected to a mobile phone or a mobile phone case, the opening accurately avoids the mobile phone lens, flash and / or the lens frame of the mobile phone case to avoid blocking the shooting function, while improving the holder's compatibility with different mobile phone models.

[0068] The magnet 7 is a 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, and is provided with a nickel-copper plating layer of 8-10 microns thick, ensuring that the magnet 7 has sufficient magnetic attraction, so that the peeling force between the bracket and the mobile phone or mobile phone case reaches more than 20N, providing a stable adsorption effect to prevent accidental falling off. The magnet 7 is arranged in the magnet accommodating space of the bottom shell 3, and the space is padded with a flexible EVA gasket 6, and a bottom membrane cover 8 is provided on the outside to effectively buffer the direct contact between the magnet and the external environment, prevent the magnet from being damaged by vibration or collision, and ensure the uniform distribution and stability of the magnetic attraction.

[0069] The foldable 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 grasping position from the back of the mobile phone / mobile phone case and can arch according to the natural curvature of the human palm and back of the hand, avoiding the palm from being straightened for a long time and significantly reducing the hand fatigue. The bottom edge of the foldable housing 4 is clamped between the bottom housing 3 and the bottom inner housing 5. A protrusion is provided on the lower side of the bottom housing 3. The protrusion passes through the assembly hole of the bottom edge of the foldable housing 4 and the bottom inner housing 5 and is fixed (such as welded) to form a stable support structure, ensuring the connection stability and structural integrity between components, effectively dispersing external pressure, preventing the foldable housing 4 from loosening or deforming during use, and thus ensuring the reliability and service life of the bracket in the folded and extended states.

[0070] The top component includes a top base 2 and a top cover 1. The top base 2 is arranged between the foldable housing 4 and the top cover 1. A connecting portion is provided on the lower side of the top cover 1 and is connected to the top end of the foldable housing 4 through the through hole 10 of the top base 2.

[0071] The top cover 1 is connected to the top base 2 in a snap - lock 11 manner, which is convenient for assembly and disassembly without special tools. At the same time, it supports printing personalized patterns on the inner side of the top cover 1, enhancing the aesthetics of the product and the user interaction experience.

[0072] In summary, the expandable mobile phone bracket of the present invention has been significantly optimized in terms of optimizing ergonomic design, avoiding lens component occlusion, maintaining stable magnetic attraction, and enhancing structural reliability, solving the pain points in the prior art and providing users with a more convenient, comfortable and durable use experience.
