Description

Field of invention The present utility model relates to the technical field of mobile phone accessories, in particular a mobile phone air cushion holder. State of the art With the increasing prevalence of smartphones, market demand for mobile phone holders as aids for watching videos, making video calls, or using the phone hands-free is steadily rising. Existing mobile phone holders come in a wide variety of designs, including foldable, telescopic, and magnetic versions. Among these, air cushion holders have gained increasing attention due to their advantages such as cushioning and shock absorption, as well as their compact storage size. However, existing air cushion phone mounts still have some problems in practical use. For example, some mounts lack an effective self-locking mechanism or a reliable retention system after compression, so unintentional opening can easily occur. A snap-fit ​​connection within the internal structure is often used to achieve self-locking. While such a design can prevent the elastic air cushion from automatically re-compressing, it also makes releasing the self-locking mechanism difficult, thus complicating the process.Furthermore, the internal structure of conventional mobile phone air cushion mounts is usually relatively simple and lacks an effective guiding and limiting structure for the internal elastic elements, so performance can easily decline with prolonged use. Therefore, there is an urgent need for a mobile phone air cushion mount with a more rational structure, greater connection stability, and a better user experience. Object of the invention The purpose of the present utility model is to provide a mobile phone air cushion holder to solve the technical problems existing in the prior art, namely that the connection stability of the mobile phone air cushion holder is low, unintentional pop-up after the compressed state easily occurs, and the internal elastic elements lack an effective guiding structure. To achieve the aforementioned purpose, the present utility model provides the following technical solution: A mobile phone air cushion holder comprising a top cover, an upper mounting base, a compressible elastic air cushion body, a lower mounting base, and a bottom cover. The surface of the elastic air cushion body is provided with several ventilation openings. The improvement consists in the further provision of a compression spring, wherein the upper mounting base has a first protrusion and the lower mounting base has a second protrusion. The top cover is connected to the upper mounting base as a single unit, and the lower mounting base is connected to the bottom cover as a single unit. The upper part of the elastic air cushion body is in a sealing connection with the top cover, and the lower part of the elastic air cushion body is in a sealing connection with the lower mounting base.The compression spring is arranged inside the elastic air cushion body, with one end of the compression spring resting on the first protrusion and the other end resting on the second protrusion. Furthermore, a magnetic connection unit is provided between the upper and lower mounting bases. The magnetic connection unit comprises a first component arranged on the upper mounting base and a second component arranged on the lower mounting base. At least one of the first and second components is a permanent magnet, and the other is a magnetically conductive element or a permanent magnet, such that a magnetic attraction is generated between the first and second components to connect the upper and lower mounting bases. Preferably, the magnetic attraction generated between the magnetic connection unit is greater than the spring force generated by compression of the compression spring, thus ensuring that the mount can be held stably in the compressed state and preventing unintentional opening due to the spring force. In certain embodiments of the present utility model, the first component is a permanent magnet and the second component is a magnetically conductive element; or the first component is a magnetically conductive element and the second component is a permanent magnet; or both the first component and the second component are permanent magnets, their opposite faces having opposite magnetic poles to enhance the magnetic attraction. The magnetically conductive element can be made of iron, iron alloys, or magnetizable metal material. To facilitate the assembly and fastening of the magnetic components, the first protrusion can be provided with a first mounting opening, and the second protrusion with a second mounting opening, wherein the first component is inserted into the first mounting opening and the second component into the second mounting opening. Regarding the connection structure, the top cover can have at least two locking hooks, and the upper mounting base is provided with locking grooves that correspond to the locking hooks. After the top cover is connected to the upper mounting base, the locking hooks engage in the locking grooves, thus achieving a stable connection. To ensure the airtightness of the elastic air cushion body, its upper section can be provided with an annular groove, with the inner surface of the top cover correspondingly featuring an annular protrusion. When the elastic air cushion body is connected to the top cover, the annular protrusion is inserted into the annular groove, thus forming a sealing structure. Similarly, the upper section of the lower mounting base can have a circular shoulder whose diameter is greater than or equal to the diameter of the inner cavity in the lower section of the elastic air cushion body. When the elastic air cushion body is connected to the lower mounting base, the inner cavity of the lower section of the elastic air cushion body is inserted into the circular shoulder, also creating a sealing structure. Furthermore, the present utility model may include a ring-shaped holder and a hinge assembly. The ring-shaped holder is provided with a permanent magnet, allowing it to adhere to the back of a mobile phone or other digital devices via the permanent magnet. The bottom cover has an annular groove on its underside, the ring-shaped holder is attached to one side of the bottom cover, and the hinge assembly connects the ring-shaped holder to the bottom cover. The ring-shaped holder can rotate relative to the bottom cover between the extended and retracted positions. When the ring-shaped holder is in the retracted position, it is at least partially received in the annular groove, and the outer surface of the ring-shaped holder is substantially flush with or below the underside of the bottom cover to maintain surface flatness.Furthermore, two arc-shaped grooves can be arranged at the bottom of the annular groove, with a permanent magnet or a magnetically conductive element being inserted in one of the arc-shaped grooves, and a part of the joint assembly being inserted into the other arc-shaped groove. The advantageous effects of the present utility model are as follows: By adding a magnetic connecting unit based on an internally arranged compression spring, the magnetic attraction is used to overcome the spring force, thereby holding the mobile phone air cushion holder in a self-locking position when compressed. This prevents unintentional opening and increases safety and user-friendliness. The two ends of the compression spring are each placed on the raised sections of the upper mounting base and the lower mounting base, effectively limiting the lateral displacement of the spring and achieving good guidance, which extends its service life. The top cover and upper mounting base, as well as the bottom cover and lower mounting base, are designed as a one-piece structure or via snap-hook locking groove connection, making the structure simple and the connection stable. The elastic air cushion body is sealed to the upper and lower covers or mounting bases by the combination of annular groove and annular protrusion as well as inner cavity and step, thereby ensuring the airtightness of the air cushion and the compression recovery. The optional ring-shaped bracket and its joint assembly offer additional support or suspension options and do not affect the surface flatness of the overall system after folding.

Obviously, the described embodiments represent only a subset of the embodiments of this utility model and not all of them. All further embodiments that are derived by persons skilled in the art in the field of this utility model without any creative activity, by reference to the embodiments of this utility model, also fall within the scope of protection of this utility model. Please refer to Figs. 1, 2, 3, 4, 5 to 6. This utility model provides a mobile phone air cushion holder 100. As shown in Fig. 1 and Fig. 6, the mobile phone air cushion holder 100 mainly comprises a top cover 10, an upper mounting base 20, a compressible elastic air cushion body 30, a lower mounting base 40, and a bottom cover 50. Several ventilation openings 31 are evenly spaced on the surface of the elastic air cushion body 30, which regulate the internal pressure during compression and rebound to avoid excessive resistance or noise. The key improvement of this embodiment lies in the additional provision of a compression spring 60. The upper mounting base 20 extends downwards and is equipped with a first projection 21, while the lower mounting base 40 extends upwards and is equipped with a second projection 41. The upper cover 10 is connected to the upper mounting base 20 as a single-piece structure by injection molding or other methods, or alternatively via a snap-fit ​​connection structure described below. The lower mounting base 40 is also connected to the lower cover 50 as a single-piece structure. The upper opening of the elastic air cushion body 30 is sealed to the underside of the upper cover 10, and the lower opening of the elastic air cushion body 30 is sealed to the top of the lower mounting base 40. The compression spring 60 is arranged in the inner cavity of the elastic air cushion body 30.Its upper end rests on the first projection 21, and its lower end rests on the second projection 41. This design allows the compression spring 60 to move along the axes of the first projection 21 and the second projection 41 during compression, effectively preventing lateral bending or slippage of the spring and ensuring that the restoring force remains stable and linear. In this embodiment, the underside of the lower cover 50 is additionally provided with an adhesive patch 54. The adhesive patch 54 is connected to the lower cover 50 by means of bonding or embedding, and its surface can be designed with various patterns. To achieve the self-locking function in the compressed state, a magnetic connecting unit 70 is arranged between the upper mounting base 20 and the lower mounting base 40. The magnetic connecting unit 70 comprises a first component 71 and a second component 72. The first component 71 is fixedly attached to the upper mounting base 20 (e.g., embedded in or on the surface of the first protrusion 21), and the second component 72 is fixedly attached to the lower mounting base 40 (e.g., embedded in or on the surface of the second protrusion 41). In this embodiment, the first component 71 is designed as a strong permanent magnet (e.g., a neodymium-iron-boron magnet), and the second component 72 is designed as a magnetically conductive element made of a material with high magnetic conductivity (e.g., pure iron or an iron-nickel alloy).When the air cushion holder 100 is compressed, the upper mounting base 20 and the lower mounting base 40 move closer together, and the distance between the first component 71 and the second component 72 decreases, gradually increasing the magnetic attraction between them. The design ensures that this maximum magnetic attraction is greater than the maximum spring force generated by the compression spring 60 after full compression, so that the upper mounting base 20 and the lower mounting base 40 adhere stably to each other and maintain the compressed state of the holder without requiring additional force from the user to hold it in place. Of course, the configuration of the magnetic connecting unit 70 is not limited to this. In other embodiments, the first component 71 can be designed as a magnetically conductive element and the second component 72 as a permanent magnet; or both the first component 71 and the second component 72 can be permanent magnets, in which case it must be ensured that the opposing surfaces form opposite magnetic poles (e.g., N pole versus S pole) in order to generate an attractive magnetic force. The material of the magnetically conductive element can be iron, iron alloys, or other metallic materials that are significantly attracted by the magnetic field. To facilitate the installation of the magnetic components, as shown in Figs. 4 and 6, the first projection 21 can be provided with a first mounting opening 22, and the second projection 41 is correspondingly equipped with a second mounting opening 42. The first component 71 is inserted into the first mounting opening 22, the second component 72 is inserted into the second mounting opening 42 and can be fixed by gluing, press fit, or similar methods. Regarding the connection between the top cover 10 and the upper mounting base 20, as shown in Figures 3 and 4, in this embodiment the inner edge of the top cover 10 is provided with at least two snap hooks 11 molded in one piece (two are shown in the example figure; the actual number can vary according to the circumferential distribution). Snap grooves 23 are arranged at the corresponding position on the outer edge of the upper mounting base 20. During assembly, the top cover 10 is placed over the upper mounting base 20, the snap hooks 11 undergo elastic deformation and engage in the snap grooves 23, thus achieving a quick-locking and secure connection between the two components. This snap-fit ​​connection structure requires no screws and simplifies the assembly process. To ensure the airtightness of the elastic air cushion body 30, the upper inner region of the elastic air cushion body 30 is provided with an annular groove 32, as shown in Fig. 5. The underside of the top cover 10 is provided with an annular protrusion 12 at the corresponding position. When the elastic air cushion body 30 is placed on the top cover 10 and connected to it, the annular protrusion 12 is tightly embedded in the annular groove 32, creating a labyrinth seal or compression seal that effectively prevents air from escaping. Similarly, the upper surface of the lower mounting base 40 is provided with a circular shoulder 43. The diameter of the circular shoulder 43 is greater than or equal to the diameter of the lower inner cavity of the elastic air cushion body 30.During assembly, the lower inner cavity of the elastic air cushion body 30 is placed over the outside of the circular shoulder 43 and a sealing connection is created by press fit or bonding. Furthermore, to extend the functionality of the holder in this embodiment, an annular bracket 80 and a hinge assembly 90 can optionally be provided. As shown in Figs. 7, 8, 9 to 10, an annular groove 51 is arranged in the central area of ​​the underside of the lower cover 50. The annular bracket 80 is ring-shaped or C-shaped and is attached to one side of the lower cover 50. The hinge assembly 90 (e.g., pivot axis, hinge structure, etc.) connects one end of the annular bracket 80 to the edge of the lower cover 50, so that the annular bracket 80 is rotatable relative to the lower cover 50; the opening and closing of the hinge assembly 90 is provided with a damping structure and can occur at any angle. The annular bracket 80 has an extended position and a folded position.In the unfolded position, the ring-shaped holder 80 protrudes from the underside of the bottom cover 50 and can serve as a finger grip to make it easier for the user to hold the phone, or as a support structure to increase stability. In the folded position, the ring-shaped holder 80 rotates and is at least partially received in the ring-shaped groove 51, with its outer surface lying largely flush with or slightly below the underside of the bottom cover 50, thus ensuring a flat surface when placed on a table and preventing wobbling. A further optimization involves the arrangement of two arc-shaped grooves 52 at the base of the annular groove 51, one of which accommodates a permanent magnet 53 or a magnetically conductive element. The annular holder 80 itself is equipped with a permanent magnet that attracts the holder 80 and prevents unintentional unfolding. The permanent magnet also allows the holder 80 to adhere to the back of a mobile phone or other digital devices. In summary, the present utility model provides a mobile phone air cushion holder 100 which, through the clever combination of the compression spring 60 with the magnetic connection unit 70, solves the problem that conventional air cushion holders cannot maintain a stable compressed state; the design with raised features for the spring's guide structure, the snap-hook connection, and the annular groove for the sealing structure increases the product's reliability, airtightness, and assembly efficiency; the optional annular bracket 80 further enhances the user experience. The structure of this design is practical, cost-effective, easily mass-producible, and has good market potential. The foregoing merely represents the preferred embodiments of the present utility model and is not intended to limit the present utility model; all modifications, equivalent replacements or improvements made in the spirit and in accordance with the principles of the present utility model shall fall within the scope of protection of the present utility model. This utility model discloses a mobile phone air cushion holder and relates to the technical field of mobile phone accessories. The holder comprises a top cover, an upper mounting base, a compressible elastic air cushion body, a lower mounting base, and a bottom cover. The top cover and the upper mounting base, as well as the lower mounting base and the bottom cover, are each connected to each other as a single-piece structure. The upper part of the elastic air cushion body is sealed to the top cover, and the lower part of the elastic air cushion body is sealed to the lower mounting base.The key improvement lies in the inclusion of a compression spring inside the elastic air cushion body. Both ends of the compression spring rest on the first protrusion of the upper mounting base and the second protrusion of the lower mounting base, respectively, providing guidance and spring force. Simultaneously, a magnetic connecting unit, consisting of at least one permanent magnet and a magnetically conductive element, is integrated between the upper and lower mounting bases. When the mount is compressed, the magnetic attraction generated by the connecting unit exceeds the spring force of the compression spring, thus achieving self-locking in the compressed state and preventing unintentional release.If an external force greater than the magnetic attraction is applied, the elastic air cushion body can return to its unfolded state, thus unfolding the holder.
