Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, specifically to a magnetic mobile phone holder. Background Technology

[0002] Existing mobile phones have MagSafe functionality, which involves embedding a ring magnet inside the phone's internal structure, using a phone case with a ring magnet, or attaching a ring magnet to the back of the phone, thus enabling MagSafe functionality. Currently, there are many mobile phone accessories on the market that can be magnetically attached to the built-in magnets of the phone, such as magnetic phone stands, magnetic phone airbag stands, or magnetic phone desktop stands. However, the magnetic products on the market are quite similar. There is still a need for a magnetic phone stand that offers a more practical design, compact size, simple operation, and convenient use, providing a better user experience.

[0003] Furthermore, regarding the patent application No. 202421736914X, entitled "A Magnetic Phone Holder," the disclosed soft rubber airbag and magnetic suction part (equivalent to the magnetic base and rotating disk in this application) are fixedly arranged. Because the magnetic suction part is attached to the back of the phone, users often rotate the face cover when using it, causing the soft rubber airbag and magnetic suction part to twist. Since the magnetic suction part is fixed, the soft rubber airbag itself will twist, making it prone to rupture and limiting its lifespan. There are no similar solutions on the market to address these problems that arise in practical use scenarios. Utility Model Content

[0004] To effectively solve the above problems, this utility model provides a magnetic mobile phone holder.

[0005] The specific technical solution of this utility model is as follows:

[0006] A magnetic phone holder is provided, wherein the magnetic phone holder is magnetically fixed to a phone having a built-in first magnetic element. The magnetic phone holder includes at least one magnetic base with a magnetic attachment corresponding to the first magnetic element, at least one rotating disk that rotates and cooperates with the magnetic base, a soft rubber airbag for gripping, and a cover for storing the compressed soft rubber airbag. The soft rubber airbag is disposed between the magnetic base and the cover.

[0007] The rotating disk rotates along the inner circumferential track of the magnetic base. The soft rubber airbag is fixedly installed on the rotating disk. A cover is fixedly installed on the side of the soft rubber airbag opposite to the rotating disk. The cover presses the end face of the soft rubber airbag against one side of the rotating disk, compressing the soft rubber airbag.

[0008] Furthermore, the rotation of the rotating disk and the magnetic base can be achieved, but is not limited to, through a protrusion and groove mechanism;

[0009] The magnetic base is a ring structure, and a limiting protrusion extends radially from the inner circumference of the ring on the magnetic base. The limiting protrusion is an arc-shaped protrusion structure.

[0010] The rotating disk forms a limiting groove corresponding to the outer peripheral recess of the limiting protrusion, and the limiting protrusion and the limiting groove are engaged with each other.

[0011] Furthermore, the soft rubber airbag is an airbag structure that is bulging in the middle, narrowed at both ends, and hollow inside. The inner diameter of the opening at one end of the soft rubber airbag is larger than the outer diameter of the opening at the other end.

[0012] The soft rubber airbag has at least one fold line on its inner peripheral sidewall for proper folding. The fold line is a recess formed by the inward concavity of the inner peripheral sidewall of the soft rubber airbag.

The adsorption sheet structure and the adsorption magnet press and store the soft rubber airbag through magnetic adsorption. After being pressed and stored, the ring of the end face with the larger inner diameter of the soft rubber airbag opening is fitted onto the other end face.

[0017] Furthermore, at least one fixing body is fitted onto one end face of the soft rubber airbag opposite to the magnetic base. The fixing body forms a second limiting hole corresponding to the end face of the soft rubber airbag. The inner circumferential side of the second limiting hole is adapted to the end face of the soft rubber airbag. The side of the fixing body opposite to the soft rubber airbag is fixed to the cover portion.

[0018] One side of the fixed base is recessed to form an exhaust groove, and the bottom side of the exhaust groove is provided with a second vent hole that communicates with the outside air.

[0019] After the face cover is fixed to the fixed base, it together with the exhaust groove forms the ventilation track;

[0020] The end face of the soft rubber airbag that is adapted to the second limiting hole has a stepped structure. The end face of the second limiting hole and the soft rubber airbag are fitted together. The adsorption sheet is fixed in the second limiting hole and presses the end face of the soft rubber airbag against the inner circumference of the second limiting hole. After the adsorption sheet is fixed, it forms a height difference with the second limiting hole and together with the cover defines the air cavity.

[0021] Furthermore, the fold crease includes a first fold crease and a second fold crease, and the two open end faces of the soft rubber airbag are the first open face and the second open face;

[0022] The diameter of the first fold is larger than the diameter of the second fold, and the opening area of ​​the first opening surface is larger than the opening area of ​​the second opening surface.

[0023] The vertical distance between the first fold crease and the first opening surface is less than the vertical distance between the first fold crease and the first opening surface.

[0024] Furthermore, the inner diameter of the first opening of the soft rubber airbag is larger than the outer diameter of the second opening.

[0025] The inner circumferential side of the first limiting hole is a through hole structure with steps. The first opening surface of the soft rubber airbag is adapted to the through hole structure, and the adsorption magnet is a stepped structure adapted to the first limiting hole. The adsorption magnet presses the end face of the soft rubber airbag against the inner side of the first limiting hole.

[0026] Furthermore, the magnetic chassis includes at least one housing and a magnetic unit that is magnetically attracted and fixed to the first magnetic element;

[0027] One side of the housing is recessed to form a first magnetic groove, and a first magnetic unit is provided in the first magnetic groove. The first magnetic unit is annular or partially annular. The first limiting hole is opened through the center of the housing.

[0028] The first magnetic attraction unit is a ring-shaped magnet assembly, or a partial ring-shaped magnet assembly;

The side of the cover is inserted into the through hole at an angle and is limited by the through hole.

[0035] The advantages of this invention are as follows: Using the aforementioned phone holder, the phone is magnetically attached to the back of the phone via Magsafe, allowing the user to hold the phone securely through the soft rubber airbag. When the phone holder is not in use, the cover is pressed against the magnetic magnet; the magnetic attraction between the cover and the magnet compresses the soft rubber airbag, effectively storing it. When wireless charging is needed, the magnetic base is removed from the back of the phone. The entire product is compact, convenient, practical, and suitable for a wider range of applications.

[0036] Furthermore, since the magnetic base and the rotating disk can rotate relative to each other, when the magnetic base is magnetically attached to the back of the phone, the soft rubber airbag and the magnetic part twist when the user twists the cover. The magnetic base is fixed, and the soft rubber airbag rotates with the rotating disk, ensuring the consistency of the shape of the soft rubber airbag and preventing it from twisting and breaking, thus greatly extending its service life.

[0037] Furthermore, the phone stand not only serves as a desktop stand for vertically supporting the phone screen, but its ingenious structural design also enhances the storage efficiency of the folding stand, thus expanding its application scenarios. Attached Figure Description

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] First Embodiment

[0058] like Figure 1-10 As shown, this embodiment provides a folding phone holder, which is magnetically fixed to a phone with a built-in first magnetic element 101. In this embodiment, the phone is a phone with MagSafe functionality, such as an Apple 12, 13, 14, 15, or 16 series phone. The first magnetic element 101 is provided inside the back of the phone. The first magnetic element 101 is a ring-shaped combination of bipolar magnets composed of tile-shaped magnets, with both magnetic poles coexisting and opposite magnetic poles. For details, please refer to [reference needed]. Figure 1 The first magnetic element 101 is indicated by the dotted line on the back of the mobile phone;

[0059] The magnetic mobile phone holder includes at least one magnetic base 1 with a magnetic attraction corresponding to the first magnetic attraction element, at least one rotating disk 2 that rotates and cooperates with the magnetic base 1, a soft rubber airbag 3 for holding, and a face cover 4 for storing the compressed soft rubber airbag 3. The soft rubber airbag 3 is located between the magnetic base 1 and the face cover 4.

[0060] The rotating disk 2 rotates along the inner circumferential track of the magnetic base 1. The rotation of the rotating disk 2 and the magnetic base 1 includes the method of using protrusions and grooves. Specifically, the magnetic base 1 is a ring structure, and a limiting protrusion 101 extends radially from the inner circumferential side of the ring of the magnetic base 1. The limiting protrusion 101 is an arc-shaped protrusion structure.

[0061] The rotating disk 2 is recessed on the outer periphery of the limiting protrusion 101 to form a limiting groove 201. The limiting protrusion 101 and the limiting groove 201 are engaged with each other. Specifically, the limiting protrusion 101 is engaged into the limiting groove 201. The rotating disk 2 and the magnetic base 1 are connected by the limiting protrusion 101 and the limiting groove 201 structure, so that the rotating disk 2 can rotate along the inner periphery of the magnetic base 1.

[0062] Furthermore, a lubricating ring 5 can be fitted inside the groove of the rotating disk 2 to help the rotating disk 2 rotate smoothly. The lubricating ring 5 includes, but is not limited to, a silicone ring or a rubber ring.

[0063] A lubrication ring 5 is provided between the limiting protrusion 101 and the limiting groove 201. The rotating disk 2 rotates along the inner circumferential track of the magnetic base 1, making it smoother to use.

[0064] A first limiting hole 201 is provided through one side of the rotating disk 2. One end face of the soft rubber airbag 3 is located in the first limiting hole 201. An adsorption magnet 202 is provided in the first limiting hole 201. The adsorption magnet 202 presses the end face of the soft rubber airbag 3 against the side of the first limiting hole 201.

[0065] The soft rubber airbag 3 is fixedly connected to the face cover 4 at the end opposite to the adsorption magnet 202. The face cover 4 and the adsorption magnet 202 press and store the soft rubber airbag 3 through magnetic adsorption.

[0066] In this embodiment, the soft rubber airbag 3 is an airbag structure that bulges in the middle and narrows at both ends, and the airbag structure is hollow inside.

[0067] In this embodiment, the inner circumferential side of the first limiting hole 201 is a through hole 3011 structure with a step, one end face of the soft rubber airbag 3 is adapted to the through hole 3011 structure, and the adsorption magnet 202 is a stepped structure adapted to the first limiting hole 201.

[0068] After the end face of the soft rubber airbag 3 extends into the inner side of the first limiting hole 201, the outer side of the end face of the soft rubber airbag 3 contacts the inner side of the first limiting hole 201, and the adsorption magnet 202, corresponding to the stepped structure of the end face, presses the end face of the soft rubber airbag 3 against the first limiting hole 201, thereby achieving the fixed positioning of the soft rubber airbag 3 and the first limiting hole 201.

[0069] Furthermore, the end face of the soft rubber airbag 3 is bonded to the first limiting hole 201 with adhesive, and the adsorption magnet 202 is bonded to the soft rubber airbag 3 with adhesive, thereby achieving a fixed connection between the soft rubber airbag 3 and the first limiting hole 201.

[0070] This describes the four corners that have been unfolded.

[0071] The face cover 4 has at least one adsorption sheet 301 structure on one side facing the soft rubber airbag 3. The adsorption sheet 301 is a stainless iron sheet and can be magnetically connected to the adsorption magnet 202.

[0072] The soft rubber airbag 3, opposite to one end face of the magnetic base 1, also has a stepped structure and is fitted with a fixing seat 302. The fixing seat 302 forms a second limiting hole 303 corresponding to the end face of the soft rubber airbag 3. The inner circumferential side of the second limiting hole 303 is adapted to the end face of the soft rubber airbag 3, and the second limiting hole 303 and the end face of the soft rubber airbag 3 are fitted together. The adsorption sheet 301 presses the end face of the soft rubber airbag 3 against the inner circumferential side of the second limiting hole 303.

[0073] The fixing base 302 and the face cover 4 are fixedly connected to each other. Specifically, the fixing base 302 and the face cover 4 are fixed by ultrasonic welding. A through hole 3011 is provided through the adsorption sheet 301, and a second vent hole 3021 is provided through the periphery of the fixing base 302. The soft rubber airbag 3 exchanges air with the outside through the through hole 3011 and the second vent hole 3021.

[0074] The cover part 4 is a flat cover structure; the soft rubber airbag 3 is an airbag structure that bulges in the middle and narrows at both ends, and the soft rubber airbag 3 has openings on both sides and is hollow inside.

[0075] A first limiting hole 201 is provided through one side of the magnetic base 1, and one end of the soft rubber airbag 3 is provided in the first limiting hole 201. One end of the soft rubber airbag 3 is fixed to the first limiting hole 201, and an adsorption magnet 202 is provided in the first limiting hole 201.

[0076] The faceplate 4 has at least one absorbent sheet 301 on the side facing the soft rubber airbag 3. An air cavity is formed on the side of the faceplate 4 facing the absorbent sheet, and at least one air intake or exhaust channel extends from the outer periphery of the air cavity. Figure 5 The dashed line shows a schematic diagram of the air exchange of the ventilation track. One end of the ventilation track is connected to the air chamber, and the other end forms a second ventilation hole 3021 on the outer surface of the cover part 4.

[0077] The adsorption sheet 301 has a through hole 3011 that is uniformly radiating outward from the center. The soft rubber airbag 3 exchanges air with the outside through the through hole 3011, the air cavity, the air track and the second air hole 3021.

[0078] The soft rubber airbag 3 is fixedly connected to the face cover 4 at one end opposite to the adsorption magnet 202. The adsorption sheet 301 and the adsorption magnet 202 press the soft rubber airbag 3 tightly and store it through magnetic adsorption. After being pressed and stored, the ring of the end face with the larger inner diameter of the opening of the soft rubber airbag 3 is fitted onto the other end face.

[0079] When the cover portion 4 presses and stores the soft rubber airbag 3 towards the magnetic base 1, the air inside the soft rubber airbag 3 is vented through the first vent 201 or the second vent 3021, so that the soft rubber airbag 3 is stored and the cover portion 4 is stored to one side of the magnetic base 1.

[0080] Furthermore, the magnetic chassis 1 includes at least one housing 102 and a first magnetic unit 104 that is magnetically fixed to the first magnetic element 101.

[0081] One side of the housing 102 is recessed to form a first magnetic groove 103. The first magnetic unit 104 is provided in the first magnetic groove 103. The first magnetic unit 104 is annular or partially annular. The first limiting hole 201 is opened through the center of the housing 102.

[0082] Specifically, the housing 102 is recessed on one side facing the mobile phone to form a ring-shaped or partially ring-shaped first magnetic groove 103. A ring-shaped or partially ring-shaped first magnetic unit 104 is arranged in the first magnetic groove 103. The magnetic poles of the first magnetic unit 104 facing the mobile phone have bipolarity with opposite magnetic poles.

[0083] The first magnetic unit 104 is configured with magnetic poles corresponding to the first magnetic element 101, so as to achieve the effect of accurate magnetic positioning of the magnetic chassis 1 with the back of the mobile phone. No specific limitation is made here.

[0084] The first magnetic attraction unit 104 is a ring-shaped magnet assembly, or a partial ring-shaped magnet assembly;

[0085] The first magnetic attraction unit 104 includes a plurality of individual magnets, each of which is a tile-shaped magnet and is radially magnetized.

[0086] like Figure 8 As shown, the magnetic pole distribution of the first magnetic attraction unit 104 is that the inner magnetic pole is the S pole and the outer magnetic pole is the N pole.

[0087] Or such as Figure 9 As shown, the magnetic poles of the first magnetic attraction unit 104 are distributed as follows: the inner magnetic pole is the N pole and the outer magnetic pole is the S pole.

[0088] The first magnetic groove 103 is provided with a cover plate 4 that seals the first magnetic groove 103;

[0089] The cover plate 4 includes, but is not limited to, a membrane, a nano sticker, or a cardboard structure.

[0090] The phone holder is magnetically attached to the back of the phone using Magsafe, allowing the user to hold the phone securely through the soft rubber airbag 3. When the phone holder is not in use, the cover 4 is pressed against the magnetic magnet 202. Due to the magnetic attraction between the magnetic piece 301 and the magnetic magnet 202, the soft rubber airbag 3 is compressed, effectively storing it. When wireless charging is needed, the magnetic base 1 is removed from the back of the phone. The entire product is compact, convenient, practical, and suitable for a wider range of applications.

[0091] In the application of the magnetic phone holder, the soft rubber airbag 3 is made entirely of silicone, thus having a through-structure. However, it is not suitable to open a separate through-vent hole in the overall structure. During the compression process, the soft rubber airbag 3 needs to expel the internal air, and during the unfolding process, the soft rubber airbag 3 needs to absorb external air to balance the internal and external air pressure and provide the softness of the soft rubber airbag 3 material to improve the grip experience. However, if a through-vent hole is directly opened, it can achieve rapid internal and external air exchange, but due to the problem of silicone material, cracks will appear after prolonged use, and the cracks will increase, reducing the product's service life. Therefore, in order to ensure the durability of the silicone material, this embodiment does not directly open a vent hole on the soft rubber airbag 3.

[0092] In order to ensure the user experience, the inventors overcame technical difficulties by venting the air inside the soft rubber airbag 3 from both the top and bottom ends. The soft rubber airbag 3 is connected to the outside air through the through hole 3011, the air cavity, the ventilation track and the second ventilation hole 3021.

[0093] In this embodiment, the soft rubber airbag 3 is made of silicone. Considering the need for repeated compression and expansion of this product—expanding when held and compressing when not held to adhere to the back of the phone—the overall thickness after compression needs to be considered. Excessive thickness after compression would severely impact the user experience. Therefore, to address this issue, the inventors designed the two ends of the soft rubber material with the aforementioned structure. After compression, the smaller inner diameter end creates a larger redundant size through compression, which is then enclosed by the larger inner diameter end. This improves the compression effect by placing the compressed airbag on the same plane, further enhancing the adsorption effect between the adsorption sheet 301 and the adsorption magnet 202. During the design and development process, the inventors conducted extensive experiments to achieve a perfect balance between the adsorption force during compression and the silicone tension during expansion. This allows for expansion without excessive force and ensures that the adsorption effect is not affected by external forces generated during various usage scenarios.

[0094] Specifically, at least one fixing body 302 is fitted onto one end face of the soft rubber airbag 3 opposite to the magnetic base 1. The fixing body 302 forms a second limiting hole 303 corresponding to the end face of the soft rubber airbag 3. The inner circumferential side of the second limiting hole 303 is adapted to the end face of the soft rubber airbag 3. The side of the fixing body 302 opposite to the soft rubber airbag 3 is fixed to the face cover 4.

[0095] One side of the fixed base 302 is recessed to form an exhaust groove 3022, and the bottom side of the exhaust groove 3022 is provided with a second vent hole 3021 that communicates with the outside air.

[0096] After the face cover 4 is fixed to the fixed base 302, the through hole 3011, the exhaust groove 3022, and the second vent hole 3021 together form the ventilation track.

[0097] The end face of the soft rubber airbag 3 that is adapted to the second limiting hole 3021 is a stepped structure. The end face of the second limiting hole 3021 and the end face of the soft rubber airbag 3 are fitted together. The adsorption sheet 301 is fixed in the second limiting hole 3021 and presses the end face of the soft rubber airbag 3 against the inner circumference of the second limiting hole 3021. After the adsorption sheet 301 is fixed, it forms a height difference with the second limiting hole 3021 and together with the cover defines the air cavity.

[0098] The space between the through hole 3011 on the adsorption sheet 301 and the second vent 3021 can form a gas flow channel. When the soft rubber airbag 3 is compressed, the internal gas of the soft rubber airbag 3 can freely exchange with the external air through the through hole 3011 on the adsorption sheet 301, the air cavity, and the second vent 3021, thereby realizing the compression and deployment of the soft rubber airbag 3.

[0099] Since this product needs to be attached to the back of the phone for a long time, the overall thickness must be taken into consideration. In order to facilitate rapid ventilation, the inventor adopted a non-one-time injection molding structure for the face cover part 4. Because one-time injection molding structure will produce a lot of defective products and cannot form a stable structure of air cavity during assembly, the inventor designed the face cover part 4 as an assembly method of fixed base and face cover. In the face cover part 4, a support protrusion is formed to hold the adsorption sheet after assembly. This not only ensures the formation of air cavity, but also avoids the problem of the adsorption sheet shaking after long-term use. If the adsorption sheet shakes, it will not be able to accurately align with the adsorption magnet, which will cause serious quality problems. At the same time, the second vent 3021 is located on the side facing the silicone air bag, which avoids the problem of accidentally blocking the second vent 3021 during the pressing process.

[0100] Meanwhile, in order to solve the above-mentioned exhaust problem and ensure the uniformity of the outermost appearance of the face cover 4, the inventors set the complex structure that would affect the appearance on the fixed base 302, ensuring the simplicity of the structure and allowing for customized patterns on the face cover by consumers through subsequent spray painting and other processes.

[0101] Since the air circulation between the inside and outside of the soft rubber airbag 3 needs to be through the second vent 3021, when the soft rubber airbag 3 is compressed between the cover part 4 and the adsorption magnet 202, the compression speed of the cover part 4 in compressing and storing the soft rubber airbag 3 can be controlled by setting the area of ​​the through hole 3011 of the second vent 3021 and the number of the second vent 3021.

[0102] During use, the phone holder can function as a phone holder and also as a stress-relieving toy for the user. By controlling the compression speed of the face cover 4 when compressing and storing the soft rubber airbag 3, the phone holder can provide a better user experience when compressed and stored.

[0103] Furthermore, in actual use, the soft rubber airbag 3 needs to be frequently pulled. The structure of the soft rubber airbag 3 makes the surface of the soft rubber airbag 3 less prone to breakage when subjected to tension, making it more durable and greatly improving the product stability and lifespan of the mobile phone holder.

[0104] Furthermore, the top side of the cover 4 is a complete planar structure, which allows users to print or DIY various patterns and shapes, enriching the usage scenarios of the phone holder and better meeting the current users' pursuit of individuality.

[0105] Second Embodiment

[0106] The second embodiment is largely the same as the above embodiments, except that, as Figure 11 As shown, the magnetic chassis 1 also includes at least one folding bracket 6, which is annular or partially annular in structure, and the folding bracket 6 is rotatably connected to the side of the housing 102.

[0107] The rotary connection method includes a pin connection method;

[0108] Alternatively, the rotating connection method may also include a connection method via a hinge structure.

[0109] The folding bracket 6 is a closed hollow ring structure or a non-closed hollow ring structure. Specifically, the housing 102 is connected to at least one folding bracket 6 that provides vertical support for the mobile phone screen by means of riveting or hinge rotation.

[0110] The folding bracket 6 rotates via a hinge, specifically by inserting a pin to achieve the folding and rotation of the folding bracket 6 on the housing 102.

[0111] Alternatively, the folding bracket 6 can be folded and rotated on the housing 102 by means of rivets;

[0112] Alternatively, the folding bracket 6 can rotate via a hinge structure, and the folding bracket 6 and the housing 102 are interconnected via a hinge structure.

[0113] In this embodiment, the folding bracket 6 is made of a magnetically attractive material. When the folding bracket 6 is folded to one side of the housing 102, the first magnetic unit 104 also has a magnetic force on the side opposite to the phone. The folding bracket 6 can be attracted to one side of the housing 102 by the magnetic force of the first magnetic unit 104 on the side opposite to the phone, thereby realizing the storage function of the folding bracket 6.

[0114] To enhance the storage function of the folding bracket 6, a storage magnet is provided on one side of the folding bracket 6 facing the first magnetic unit 104. The folding bracket 6 is more securely magnetically attached to one side of the housing 102 through the storage magnet.

[0115] The storage magnets include, but are not limited to, magnets and iron sheets.

[0116] The folding phone stand can be magnetically attached to the back of a phone or a phone case with MagSafe. The soft rubber airbag 3 makes it easy for the user to hold the phone or to support the phone in landscape mode. When the folding stand 6 is folded, it can support the phone in portrait mode.

[0117] The folding bracket 6 is magnetically attracted to the housing 102. The folding bracket 6 is stored on one side of the housing 102, making storage simple and convenient. It makes full use of the magnetic force of the first magnetic unit 104 opposite to the magnetic field on one side of the phone. The phone stand can not only be used as a desktop stand for vertical screen support, but also has a clever structural design that improves the storage effect of the folding bracket 6. The usage scenarios are more diverse.

[0118] Third Embodiment

[0119] like Figure 12-14 As shown, the fourth embodiment is mostly the same as the above embodiments, except that at least one buckle through hole 7 is provided through one side of the magnetic base 1, and the rotating disk 2 extends a buckle body 701 from one side of the buckle through hole 7.

[0120] The buckle hole 7 is a through hole structure on one side of the magnetic base 1. The buckle body 701 is a protrusion extending towards the center of the magnetic base 1. When the cover part 4 is tilted towards the buckle hole 7, the side of the cover part 4 is inserted into the buckle hole 7, and the buckle body 701 limits the tilting of the cover part 4 relative to the magnetic base 1.

[0121] When the phone holder is magnetically attached to the back of the phone, and the phone is used in landscape mode, the tilted arrangement of the front cover 4 and the magnetic base 1 allows the phone holder to function as a desktop stand, thus enriching the usage scenarios of the phone holder.

[0122] Fourth embodiment

[0123] like Figure 15-18 As shown, the fourth embodiment is mostly the same as the above embodiments, except that the soft rubber airbag 3 is an airbag structure that is bulging in the middle, narrowed at both ends, and hollow inside. The inner diameter of the opening at one end of the soft rubber airbag 3 is larger than the outer diameter of the opening at the other end.

[0124] The soft rubber airbag 3 has at least one fold line on its inner peripheral sidewall for proper folding. The fold line is a recess formed by the inward concavity of the inner peripheral sidewall of the soft rubber airbag 3. When the soft rubber airbag 3 is compressed or unfolded, the fold line is parallel to the magnetic base 1 and the cover portion 4.

[0125] In this embodiment, the fold line includes a first fold line 801, which is a circular recessed structure. In other embodiments, the first fold line 801 can be an arc-shaped recessed structure or a dot-shaped recessed structure. The shape of the first fold line 801 is only to realize the soft rubber airbag 3 in compression and storage. The soft rubber airbag 3 can be folded and compressed along the position of the first fold line 801.

[0126] Furthermore, the fold line includes a second fold line 802, which is provided on the inner peripheral sidewall of the soft rubber airbag 3, such as... Figure 15 As shown, the second fold 802 and the first fold 801 are the dotted parts in the figure, indicating the structural positions of the inner peripheral wall of the soft rubber airbag 3. The first fold 801 and the second fold 802 are located on the inner peripheral sidewalls of the soft rubber airbag 3 at different heights, and the diameter of the first fold 801 is larger than the diameter of the second fold 802.

[0127] The fold lines include a first fold line 801 and a second fold line 802, and the two open end faces of the soft rubber airbag 3 are a first open face 803 and a second open face 804.

[0128] The diameter of the first fold 801 is larger than the diameter of the second fold 802, and the opening area of ​​the first opening surface 803 is larger than the opening area of ​​the second opening surface 804.

[0129] The vertical distance between the first fold 801 and the first opening surface 803 is less than the vertical distance between the first fold 801 and the first opening surface 803.

[0130] In this embodiment, the silicone structure features of the soft rubber airbag 3 are the result of the inventor's longest-term experimental testing. In terms of the silicone structure, firstly, it is necessary to achieve the effect of thin overall thickness when pressed down; secondly, it is necessary to achieve the effect of comfortable grip; and thirdly, it is necessary to achieve the effect of rapid unfolding when the elastic tension of the silicone is superimposed with the external force applied.

[0131] The inventor provided the first fold line 801 and the second fold line 802 on the inner sidewall of the soft rubber airbag 3, and the first fold line 801 and the second fold line 802 were respectively equidistant from the highest point of the soft rubber airbag 3 when it was bulging in the middle.

[0132] The first effect is that during the compression process, the first fold line 801 and the second fold line 802 are subjected to force first, and are preferentially bent according to the direction of the first fold line 801 and the second fold line 802. Since the distance is the same and the arc is the same, the bending effect is consistent. Thus, during the compression process, the uniform compression of the entire soft rubber airbag 3 is ensured. This ensures that after compression, one end of the first opening surface 803 of the soft rubber airbag 3 is uniformly wrapped around one end of the second opening surface 804, ensuring the thinnest size after compression. It also ensures the precise magnetic alignment of the adsorption magnet 202 and the adsorption sheet. Precise alignment further ensures the magnetic force after compression and can avoid the unfolding caused by accidental external force.

[0133] The second effect is that, when unfolded, during the gripping process, the first point of contact when the fingers clamp the silicone airbag is the highest point of the bulge in the middle of the soft rubber airbag 3. After the highest point is subjected to force, the first fold line 801 and the second fold line 802 are simultaneously subjected to force and expand outward, which avoids the situation where uneven tension causes the soft rubber cavity to deform randomly, thus improving the gripping comfort.

[0134] The third effect is that the silicone groove is actually compressed during production. This can be understood as the silicone density of the groove being different from that of other parts. The technical effect it achieves is specifically reflected in the structural features. After compression, the tension of the first fold line 801 and the second fold line 802 is different from the tension of other parts of the soft rubber airbag 3. However, after being combined and superimposed, and after repeated experimental tests, the effect of rapid unfolding is finally achieved when the elastic tension of the silicone is superimposed with the external force applied.

[0135] For those skilled in the art, any changes, modifications, substitutions, and variations made to the embodiments based on the teachings of this utility model, without departing from the principles and spirit of this utility model, still fall within the protection scope of this utility model.
