Description

[Technical Field]

[0001] The present application relates to the technical field of electronic device accessories, and in particular to a protective shell with a magnetic adsorption stand. [Background technology]

[0002] As we all know, smartphones and tablet PCs belong to the category of electronic products and are common consumer goods in people's lives.

[0003] To facilitate charging and eliminate the limitations of wired charging, smartphones and tablet PCs equipped with internal wireless charging units have emerged, enabling the smartphone or tablet PC to be wirelessly charged using an external wireless charger. Subsequently, to ensure a stable connection between the smartphone or tablet PC and an external accessory (e.g., a card holder, a wireless charger, etc.), a magnetic ring assembly is built into the smartphone or tablet PC, and the external accessory also has the same magnetic ring assembly built into it, allowing the smartphone or tablet PC and the external accessory to be easily attracted to each other and fixed relative to each other via the magnetic ring assembly, greatly facilitating user use.

[0004] On the other hand, many users are accustomed to attaching a protective shell to their smartphone or tablet PC, and the thickness of the protective shell is likely to affect the magnetic attraction force between the external accessory and the smartphone or tablet PC, resulting in a weak connection between the external accessory and the smartphone or tablet PC. Therefore, it has become common practice to realize the magnetic attraction connection between the external accessory and the protective shell by incorporating a magnetic ring assembly into the protective shell.

[0005] For ordinary protective shells, this method is relatively simple since there are no other functional accessories, and the installation of the magnetic ring assembly does not affect the function of the protective shell.

[0006] However, in the case of a protective shell with a stand, the built-in magnetic ring assembly affects the function of the stand to some extent. Because the magnetic ring assembly occupies a large area of ​​the back plate of the protective shell, the stand can only be installed at the edge of the back plate of the protective shell. As a result, when the stand is up, the center of gravity of the smartphone or tablet PC is offset, making it unstable and prone to tipping over. Similarly, the installation of the stand also affects to some extent the magnetic attraction between the external accessories and the protective shell. Summary of the Invention

[0007] In view of the above circumstances, the present application proposes a protective shell with a magnetic adsorption stand, which includes a back plate, a side frame, and a magnetic adsorption support assembly, wherein the side frame is arranged around the periphery of the back plate, and the magnetic adsorption support assembly is rotatable relative to the back plate or the side frame to support the protective shell with a magnetic adsorption stand.

[0008] In one embodiment, the magnetically attractive support assembly is made of a magnet or a material that can be magnetically attracted to a magnet.

[0009] In one embodiment, the magnetically attractive support assembly includes a support member and a magnetically attractive member, and the magnetically attractive member is fixedly or detachably connected to the support member. [Effects of the Invention]

[0010] According to the protective shell with magnetic adsorption stand of the present application, the magnetic adsorption support assembly is installed so as to be made of a magnet or a material that can be magnetically attracted to a magnet, or the magnetic adsorption support assembly is installed as two parts, a support member and a magnetic adsorption member, so that the support assembly has both a stand function and a magnetic adsorption function. When support is required, support can be achieved by simply rotating the magnetic adsorption support assembly. When it is required to fix a wireless charger or fix the protective shell to a vehicle stand, etc., adsorption can be achieved by the magnetic adsorption of the magnetic adsorption support assembly.

[0011] Furthermore, the magnetic adsorption support assembly is installed in the middle area of ​​the back plate, which ensures the stability of the support provided by the stand, and the support assembly is installed in a ring shape, which completely avoids the wireless charging area of ​​the mobile phone and prevents the installation of the stand from affecting the wireless charging function of the mobile phone.

[0013] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structure or arrangement of elements illustrated below or in the drawings. The present application may be embodied in other forms. It should also be understood that the words and terminology used herein are for descriptive purposes only and should not be construed as limiting. As used herein, words such as "comprises," "has," "has," and similar words are meant to include the items listed thereafter, equivalents thereof, and additional items thereof. In particular, when "a certain element" is described, the present application does not limit the number of such elements to one, but may include a plurality of such elements.

[0014] Example 1 1 , a protective shell with a magnetic adsorption stand 100 is attached to an electronic device and is used in combination with an external wireless charging device to wirelessly charge the electronic device. The protective shell with a magnetic adsorption stand 100 includes a back plate 10, a side frame 20, and a magnetic adsorption support assembly 30. The side frame 20 is disposed around the periphery of the back plate 10 to define a receiving chamber for receiving the electronic device, and the magnetic adsorption support assembly 30 is rotatable relative to the back plate 10 or the side frame 20 to support the protective shell with a magnetic adsorption stand 100.

[0015] The magnetic support assembly 30 may be made of a magnet or a material that can be magnetically attracted to a magnet. For example, the magnetic support assembly 30 may be made of iron. In a situation where magnetic attraction is required, simply aligning the magnetic support assembly 30 with a corresponding accessory with a magnet allows the accessory and the assembly 30 made of magnetically attractable material to be attracted to each other.

[0016] In another embodiment, as shown in FIG. 2 , the magnetic support assembly 30 includes a support member 32 and a magnetic support member 34. The magnetic support member 34 is attached to the support member 32, thereby providing the magnetic support assembly 30 with a magnetic attraction function. The magnetic support member 34 may be fixedly or detachably connected to the support member 32. The detachable connection allows the magnetic support member 34 and the support member 32 to be freely combined, allowing them to be combined when the magnetic attraction function is required and disassembled when the magnetic attraction function is not required, achieving flexible use. Furthermore, when the electronic device is placed in the housing, the magnetic support member is approximately aligned with the magnetic portion of the electronic device. In this way, the magnetic support member does not affect the normal operation of the components inside the electronic device.

[0017] 3, in one embodiment, the support member 32 is annular and has a receiving portion for receiving the magnetically attracting member 34. In this embodiment, the receiving portion is a receiving groove 36, and the magnetically attracting member 34 is also annular and is placed in the receiving groove 36. In other embodiments, the receiving portion may be a receiving hole or other structure that can receive the magnetically attracting member 34. The support member 32 includes a non-insulating portion 321 and an insulating portion 323. The non-insulating portion 321 is annular and includes annular segment 321A and an open segment 321B. The insulating portion 323 is provided in the open segment 321B, and both ends of the insulating portion 323 are connected to the annular segment 321A. The annular segment 321A includes a first end and a second end, the first end and the second end being the beginning and end of the annular segment 321A, the first end and the second end being spaced apart and combining to form an open segment 321B, and the insulating portion 323 is disposed within the open segment 321B, and the insulating portion 323 is connected to the first end and the second end, thereby arranging the entire support member 32 in a closed loop. Optionally, the insulating portion 323 includes a plastic material. Optionally, the insulating portion 323 can also be made of wood or ceramic.

[0018] Typically, the support member 32 is made of a metal or alloy material to ensure its strength and service life. When metal foreign matter is present in the energy transmission area of ​​a wireless charging system, a portion of the electrical energy is consumed by the metal due to the eddy current effect in the metal, resulting in a certain impact on the power and efficiency of wireless electrical energy transmission. More seriously, the eddy current effect in the metal generates a large amount of heat, causing the wireless charger and electronic devices such as mobile phones to become hot, further reducing charging efficiency. In particular, when the support ring 32 is annular, the annular support ring 32 confines the eddy currents within the ring, significantly affecting the power and efficiency of wireless electrical energy transmission. The insulating portion 323 provides an opening for eddy current release in the annular support ring 323, thereby eliminating the eddy current effect caused by the metal or alloy support member 32.

[0019] Furthermore, the surface of the insulating portion 323 is flush with the surface of the annular segment 321A, so that the addition of the insulating portion 323 does not affect the flatness of the entire surface of the support ring 32, nor does it affect the magnetic attraction with other accessories. In another embodiment, the inner ring of the annular segment 321A has a first side, and the insulating portion 323 has a second side, and the first side and the second side are in the same arcuate plane, thereby improving the feel.

[0020] Optionally, the magnetic attraction member 34 includes at least one of an iron plate and a magnetic ring. In this embodiment, the magnetic attraction member 34 is a magnetic ring, and the magnetic ring may include a plurality of magnetic members arranged in an annular pattern at intervals. In one embodiment, the magnetic attraction support assembly 30 further includes an adhesive layer 38, which is disposed in the receiving groove 36, and the magnetic attraction member 34 is attached to the receiving groove 36 via the adhesive layer 38. Optionally, the adhesive layer 38 is formed by curing at least one of a 3M adhesive or a liquid adhesive. Furthermore, the magnetic attraction support assembly 30 further includes a decorative layer 39, which is disposed in the receiving groove 36 and covers the magnetic attraction member 32, shielding the magnetic attraction member 32 and improving its appearance. Optionally, the decorative layer 39 is a Mylar sheet.

[0021] 1, the backplate 10 is divided into a first region 10A, a middle region 10B, and a second region 10C arranged in that order along the length of the backplate 10. The magnetically attached support assembly 30 includes a storage state, where the magnetically attached support assembly 30 is located in the middle region 10B when in the storage state. The magnetically attached support assembly 30 also includes a support state, where the orthogonal projection of the magnetically attached support assembly 30 is located in the middle region 10B when the opening angle of the magnetically attached support assembly 30 is 90 degrees or less, with the backplate 10 as the projection plane. The orthogonal projection of the magnetically attached support assembly 30 is located in the second region 10C when the opening angle of the magnetically attached support assembly 30 is 90 degrees or more. In another embodiment, when the rotating part of the magnetic adsorption support assembly 30 is located at the boundary between the first region 10A and the intermediate region 10B, when the opening angle of the magnetic adsorption support assembly 30 is 90 degrees or more, the orthogonal projection of the magnetic adsorption support assembly 30 is located in the first region 10A.

[0022] 4-6, in one embodiment, the magnetic attraction support assembly 30 further includes a fixing member 37, which is fixedly connected to the backplate 10, and the magnetic attraction support assembly 30 is rotatably connected to the fixing member 37 via the connecting portion 35. The fixing member 37 and the insulating portion 323 are located at opposite ends of the annular segment 321A.

[0023] In one embodiment, the insulating portion 323 is disposed opposite the connecting portion 35, thereby facilitating rotation of the magnetic adsorption support assembly 30 and allowing the magnetic adsorption support assembly 30 to rotate relatively. Optionally, the rotatable angle of the magnetic adsorption support assembly 30 includes 0-180°, and the optimal rotatable angle of the magnetic adsorption support assembly 30 is 0-135°. Furthermore, a pull tab may be further disposed on the insulating portion 323, which allows the magnetic adsorption support assembly 30 to be easily opened during use.

[0024] In one embodiment, a receiving groove 11 is provided in the back plate 10, the fixing member 37 is installed in the receiving groove 11, and when the magnetic attraction support assembly 30 is in the stored state, the support member 32 and the magnetic attraction member 34 are both located in the receiving groove 11. By providing the receiving groove 11, when the magnetic attraction support assembly 30 is in the stored state, the surface of the magnetic attraction support assembly 30 is flush with the back plate 10, which minimizes the possibility of the magnetic attraction support assembly 30 causing the surface of the back plate 10 to become uneven during wireless charging.

[0025] In one embodiment, the magnetic attraction member 34 and the magnetic attraction support assembly 30 have an optimal size range to ensure optimal function, where the thickness of the magnetic attraction member 34 is 0.3 mm to 4 mm, with an optimal thickness of 0.7 mm, the inner diameter of the magnetic attraction member is 40 mm to 52 mm, with an optimal inner diameter of 46 mm, the outer diameter of the magnetic attraction member is 40 mm to 52 mm, with an optimal outer diameter of 54 mm, the thickness of the magnetic attraction support assembly 30 is 1 mm to 5 mm, with an optimal thickness of 1.65 mm, the inner diameter of the support member 32 is 38 mm to 50 mm, with an optimal inner diameter of 44 mm, the outer diameter of the support member 32 is 50 mm to 62 mm, with an optimal outer diameter of 56.7 mm. As can be seen, the inner diameter of the magnetic attraction member 34 is less than its outer diameter, and the inner diameter of the support member 32 is also less than its outer diameter.

[0026] In one embodiment, a magnetic coupling area is provided around the magnetic adsorption support assembly 30, and the distance between the center of the magnetic coupling area and the upper edge of the back plate 10 is 77 mm to 97 mm, or the distance between the center of the magnetic coupling area and the side edge of the back plate 10 is 40 mm to 52 mm. This allows the magnetic adsorption support assembly to be located approximately at the center of the back plate, and when the protective shell is attached to the mobile phone, the magnetic adsorption support assembly can avoid the wireless charging area and not interfere with wireless charging.

[0027] In one embodiment, at least a portion of the magnetic support assembly 30 is rotatable relative to the backplate 10 to form an included angle with the backplate 10, and the included angle ranges from 0 to 135°.

[0028] 7, the magnetic attraction member 34 includes a plurality of magnetic members, which are spaced apart and arranged in a circular or arc-like configuration. In the illustrated embodiment, the magnetic members are first spaced apart and arranged in an arc-like configuration, and then four of the arc-shaped magnetic attraction members 30 are spaced apart and arranged in a circular configuration, thereby increasing the magnetic force of the magnetic attraction member 30.

[0029] 7, in the embodiment shown in Fig. 7, the fixed member 37 includes a rotating element 37A and a first fixed member 37B, the first fixed member 37B is fixedly connected to the back plate 10 or the side frame 20, and the support member 32 is rotatably connected to the first fixed member 37B via the rotating element 37A, thereby allowing the support member 32 to rotate relative to the back plate 10 or the side frame 20 to form support. Furthermore, the first fixed member 37B is located inside the back plate 10 or the side frame 20.

[0030] In one embodiment, the fixing member 37 further includes a second fixing member 37C, which is fixedly connected to the support member 32, and the first fixing member 37B is rotatably connected to the second fixing member 37C via a rotation element 37A, so that the support member 32 can rotate relative to the back plate 10 or the side frame 20 to form support. Furthermore, the second fixing member 37C is located on the inner side of the back plate 10 or the side frame 20. By providing the first fixing member 37B and the second fixing member 37C on the inner and outer sides of the back plate 10 or the side frame 20, respectively, the overall thickness of the fixing member 37 can be reduced to a certain extent, and the support member 32 can be flush with or slightly protrude beyond the back plate 10 when in the retracted state, improving the user experience. Furthermore, the fact that the support member 32 is flush with the back plate 10 can to a certain extent reduce the impact of the support member 32 on the appearance and feel of the protective shell.

[0031] Example 2 The protective shell 100 with magnetic adsorption stand of this embodiment is the same as that of embodiment 1, except that the fixing member 37 is fixedly connected to the side frame 20, and the magnetic adsorption member 34 has an opening that separates the annular magnetic adsorption member 34.

[0032] As shown in FIG. 9 , the protective shell with magnetic adsorption stand 100 includes a back plate 10, a side frame 20, and a magnetic adsorption support assembly 30 attached to the side frame 20. The side frame 20 is made of a material such as silicone, PC, TPU, or a combination thereof. The protective shell with magnetic adsorption stand 100 includes a bottom wall having an inner surface and an outer surface opposite each other, and the inner surface of the bottom wall of the protective shell with magnetic adsorption stand 100 has a storage position for storing a mobile terminal. The mobile terminal may be various portable electronic devices such as a mobile phone or a tablet PC. In this application, the mobile terminal is described as a mobile phone.

[0033] In some embodiments, the protective shell with magnetic adsorption stand 100 further includes at least one side wall extending from the bottom wall, which together with the bottom wall form a storage space for storing the mobile terminal. In the illustrated embodiment, the protective shell with magnetic adsorption stand 100 includes four side walls, which together with the bottom wall form a storage space for storing the mobile terminal (e.g., a mobile phone).

[0034] The magnetic adsorption support assembly 30 can be rotated between a plurality of positions relative to the protective shell with magnetic adsorption stand 100, including one folded position and at least one unfolded position. Figure 9 shows the folded position of the magnetic adsorption support assembly 30, in which the magnetic adsorption support assembly 30 is stored in the back plate 10 to avoid interfering with any operation of the mobile phone (e.g., the mobile phone being placed flat on a desk, the mobile phone being placed in a clothing pocket, or the mobile phone being placed on a wireless charger for charging, etc.).

[0035] 10 shows the deployed position of the magnetic adsorption stand assembly 30, which functions as a mobile phone holder. At this time, the magnetic adsorption stand assembly 30 forms a specific angle with the back plate 10, so that the mobile phone can be supported at a specific angle on a flat surface.

[0036] 11 shows the deployed position of the magnetic support assembly 30, which functions as a pull ring. At this time, the magnetic support assembly rotates 180 degrees until it is flush or parallel with the backplate 10. As can be appreciated, although two example deployed positions have been given above, in other embodiments, the magnetic support assembly may have other deployed positions and be positioned to form other angles with the backplate 10.

[0037] 12 , in the illustrated embodiment, the magnetic support assembly 30 is fixedly attached to the outside of the side frame 20 via rivets 41, and the side frame 20 is provided with recessed mounting portions 42 for riveting the magnetic support assembly 30. In other embodiments, the magnetic support assembly 30 may be attached to the backplate 10.

[0038] 13 , in the illustrated embodiment, the magnetic support assembly 30 includes a rotating shaft 43, a fixed member 37 rotatably connected to the rotating shaft 43, and a support member 32 non-rotatably connected to the rotating shaft 43. The fixed member 37 is fixedly attached to a mounting portion 42 of the side frame 20 via a rivet 41, thereby attaching the magnetic support assembly 30 to the protective shell with magnetic stand 100. The thickness of the fixed member 37 is approximately the same as the depth of the recess in the mounting portion 42. The rotating shaft 43 allows the support member 32 to rotate relative to the fixed member 37, and therefore, the protective shell with magnetic stand 100 can also rotate between the folded position and at least one unfolded position. In different positions, the support member 32 can function as a mobile phone holder or a pull ring. The fixed member 37 is typically made of high-strength metal.

[0039] A pivotal connection 45 is formed on the side edge of the fixed member 37, and the pivotal connection 45 is rotatably mounted on the rotary shaft 43, specifically, mounted on the middle segment of the rotary shaft 43. As shown in Fig. 13, in the illustrated embodiment, the pivotal connection 45 is formed by winding the side edge of the fixed member 37 into a tubular shape, and after winding to form the tubular pivotal connection 45, the end of the side edge of the fixed member 37 is separated from the inner wall surface of the pivotal connection 45. The separated state means that the end is not fixedly joined, and the end may or may not contact the inner wall surface.

[0040] 14 , there is shown a rotation stopper return mechanism formed between the pivot portion 45 and the rotating shaft 43. The outer peripheral surface of the rotating shaft portion located within the pivot portion 45 of the rotating shaft 43 has a first flat surface 431 and a first arcuate surface 432 connected to the first flat surface 431. A second flat surface 451 and a second arcuate surface 452 are provided on the inner wall surface of the pivot portion 45. When the support member 32 is in the folded position, the first flat surface 431 of the rotating shaft 43 and the second flat surface 451 of the pivot portion 45 are in close contact with each other, and the first arcuate surface 432 of the rotating shaft 43 and the second arcuate surface 452 of the pivot portion 45 are in close contact with each other.

[0041] In the absence of an external force to open the support member 32, the rotating shaft 43 and the pivoting portion 45 are fixed relative to each other, maintaining the support member 32 in the folded position. When a user manually operates the support member 32 and rotates the support member 32 away from the folded position (i.e., to the unfolded position), the portion of the rotating shaft located within the pivoting portion 45 presses against the inner wall surface of the pivoting portion 45 as it rotates, stretching the end of the side edge of the riveted fixing member 37 and increasing the inner diameter of the pivoting portion 45, thereby enabling rotation between the pivoting portion 45 and the rotating shaft 43. When a user rotates the support member 32 from the unfolded position to the folded position, the user manually rotates the support member 32 at an initial stage, and then the portion of the fixing member 37 adjacent to its end simply elastically presses against the rotating shaft, automatically returning the support member 32 to the folded position and maintaining it there.

[0042] 12 and 13 , a connecting portion 321 is provided on the support member 32 adjacent to the fixed member 37, and the connecting portion 321 is fixedly connected to the rotating shaft 43 so that the connecting portion 321 and the rotating shaft 43 do not rotate relative to each other. In the embodiment shown, the connecting portion 321 includes at least one connecting pipe 322, which is fitted around the rotating shaft 43, and a damping material is installed between the connecting pipe 322 and the rotating shaft 43 to increase friction between the connecting pipe 322 and the rotating shaft 43, so that the connecting pipe 322 and the rotating shaft 43 are fixed relative to each other and do not rotate relative to each other, and therefore the support member 32 does not rotate relative to the rotating shaft 43. In the illustrated embodiment, the connecting portion 321 is provided with two connecting pipes 322, which are located on both sides of the fixed member 37 and fitted to both ends of the rotating shaft 43. The damping material is the damping pipes 323, and one damping pipe 323 is interposed between each connecting pipe 322 and the rotating shaft 43.

[0043] 11 and 13, the support member 32 has opposing annular inner surface 324 (see FIG. 11) and annular outer surface 325. When in the folded position, the annular inner surface 324 of the support member 32 is in close contact with the outer surface of the backplate 10. The backplate 10 is provided with a storage groove 11 that matches the shape of the support member 32. When in the folded position, the support member 32 is received within the storage groove 11, and the annular outer surface 325 of the support member 32 is flush with the outer surface of the backplate 10. The backplate 10 is provided with a recess 12 on the outside of the storage groove 11 that functions as a pull tab. The recess 12 communicates with the storage groove 11, allowing the user to easily open the support member 32 from the folded position. In the embodiment shown, the recess 12 is provided on the outer periphery of the storage groove 11, away from the mounting portion 42.

[0044] The support member 32 is non-magnetically permeable and is generally made of an alloy material such as an aluminum alloy or zinc alloy. Magnetically attractive members 34 are provided on the annular outer surface 325. The magnetically attractive members 34 are distributed circumferentially on the annular outer surface 325, and have notches 341 that penetrate radially in the circumferential direction. In the illustrated embodiment, two magnetically attractive members 34 are provided. Each magnetically attractive member 34 has a curved, elongated shape. More specifically, the magnetically attractive member 34 may be an iron plate. The magnetically attractive members 34 have two circumferential ends 342 that are opposite each other in the circumferential direction. The adjacent circumferential ends 342 of the two magnetically attractive members 34 form two notches 341 spaced a predetermined distance apart.

[0045] The magnetic attraction member 34 is attached to the annular outer surface 325, thereby securing the mobile device mounted inside the protective shell 100 to other objects through magnetic attraction. One application scenario involves attaching the mobile device to a wireless charger through magnetic attraction for wireless charging. A wireless charger typically includes a transmitter coil and a magnet positioned around the transmitter coil, while a receiver coil for wireless charging, such as a mobile phone, is installed inside the mobile device. Regarding the position of the magnetic attraction member 34 on the support member 32, when the support member 32 is in the folded position, the magnetic attraction member 34 is positioned radially around the receiver coil of the mobile phone mounted inside the protective shell 100. During wireless charging, the receiver coil of the mobile phone faces the transmitter coil of the wireless charger, and the magnetic attraction member 34 faces the magnet of the wireless charger, positioning the mobile phone on the wireless charger through magnetic attraction. By providing the above-mentioned notch 341, it is possible to effectively reduce the disturbance induction and heat generation during wireless charging, provided that the magnetic attraction member 34 completes the magnetic positioning function, thereby avoiding or reducing the impact of the magnetic attraction member 34 on wireless charging.

[0046] In the illustrated embodiment, a mounting groove 326 is provided in the annular outer surface 325, and the magnetically attracting member 34 is mounted in the mounting groove 326. The outer surface of the magnetically attracting member 34 does not exceed the annular outer surface 325, and may be lower than the annular outer surface 325 or flush with the annular outer surface 325. The magnetically attracting member 34 is fixed in the mounting groove 326, for example, by adhesive. The magnetically attracting member 34 is mounted in the mounting groove 326, and the outer surface of the magnetically attracting member 34 does not exceed the annular outer surface 325. Therefore, the installation of the magnetically attracting member 34 does not increase the distance between the receiving coil of the mobile phone and the transmitting coil of the wireless charger, thereby avoiding a decrease in charging efficiency due to the increased distance.

[0047] Although the illustrated embodiment shows an example of two magnetically attractive members 34, in other embodiments, one elongated magnetically permeable member may be provided on the annular outer surface 325, and the notch is formed between two circumferential ends of the one elongated magnetically permeable member. In some embodiments, two or more magnetically permeable members may be provided, and the radially penetrating notch is formed between adjacent circumferential ends of any two adjacent magnetically permeable members.

[0048] Example 3 The protective shell 100 with a magnetic adsorption stand according to this embodiment is similar to that of the first embodiment, except that the fixing member 37 is also annular and has an opening.

[0049] As shown in FIGS. 15-18 , the protective shell with magnetic adsorption stand 100 includes an annular fixing member 37, a first snap 50, and an annular metal support member 32. The fixing member 37 has a first ring inner wall, a first ring outer wall, a first surface 371 located between the first ring inner wall and the first ring outer wall, and a second surface 372 opposite the first surface 371. The first snap 50 has opposing fixed and free ends 501 and 502. The fixed end 501 is connected to the fixing member 37, and the free end 502 is located on the side of the fixed end 501 closest to the first ring inner wall of the fixing member 37 and is elastically rotatable around the fixed end 501 to move toward or away from the first surface 371. A first engagement groove 503 is formed in the free end 502. The support member 32 is stacked on the first surface 371 of the fixing member 37, and one end of the support member 32 is rotatably connected to the fixing member 37.

[0050] For example, as shown in FIG. 15 , when the magnetically attached support assembly 30 is in a closed state, the support member 32 substantially overlaps the fixing member 37. As shown in FIG. 17 , when the magnetically attached support assembly 30 is in an open state, the support member 32 rotates around the fixing member 37, forming a predetermined angle with the fixing member 37 to support an electronic device. The support member 32 has opposing second ring inner and outer walls. As shown in FIG. 18 , which is an exploded structural diagram of FIG. 17 , the support member 32 is provided with a first opening 133 that connects the second ring inner and outer walls. Specifically, the support member 32 engages with, for example, the first engagement groove 503 and is rotatable relative to the first engagement groove 503, thereby enabling the support member 32 to rotate toward or away from the first surface 371 relative to the fixing member 37. The first opening 133 is located, for example, on the side of the support member 32 away from the first snap 50.

[0051] Of course, achieving a rotatable connection using the first snap 50 is merely an illustrative example of one embodiment of the present invention. The rotatable connection between the support member 32 and the fixing member 37 can also be achieved by a pin connection, etc., and this embodiment is not limited thereto. The fixing member 37 and the support member 32 can, for example, have an overall annular sheet structure. The fixing member 37 can also be a ring of other shapes, rather than a ring. The size of the ring of the support member 32 can be compatible with commercially available MagSafe magnetic adsorption rings. For example, the support member 32 can be a magnetically adsorbable metal ring, such as an iron ring, so that the magnetic adsorption support assembly 30 can be compatible with a MagSafe magnetic adsorption car stand or a MagSafe wireless charger and achieve a relatively good magnetic adsorption effect. Furthermore, the first opening 133 in the support member 32 prevents the support member 32 from forming a complete metal ring. This reduces heat generation and improves charging efficiency when used in combination with a magnetic adsorption wireless charger.

[0052] In one embodiment, as shown in FIGS. 17 and 18 , the magnetic adsorption support assembly 30 further includes an insulating portion 323 installed within the first opening 133. This ensures charging efficiency while also ensuring the aesthetic appeal and stability of the electronic device stand. The fixing member 37 may be a metal iron ring or a non-metallic material. If the fixing member 37 is made of a magnetically adsorbable metal material such as an iron ring, it can be directly attached to the back of the electronic device without the need for adhesive when a magnetic member is installed on the back of the electronic device itself. The magnetic adsorption support assembly 30 can be easily removed when not in use, simplifying operation. Similarly, as shown in FIGS. 18 and 19 , if the fixing member 37 is made of a metal material, the fixing member 37 may further include a second opening 114 corresponding to the position of the first opening 133, similarly improving charging efficiency. The first snap 50 may be made of a metal elastic plate or other material with elastic deformation properties. The first snap 50 may be integrally installed with the fixing member 37.

[0053] 15 and 17, FIG. 15 is a structural schematic diagram of the magnetic adsorption support assembly 30 in a closed state. FIG. 17 is a structural schematic diagram of the magnetic adsorption support assembly 30 in an open state. When using the magnetic adsorption support assembly 30, the second surface 372 of the fixing member 37 can be attached to the back surface of an electronic device or the back surface of a protective shell. In the closed state, the support member 32 is stacked on the first surface of the fixing member 37 and substantially overlaps the fixing member 37. At this time, the free end 502 of the first snap 50 fastens the support member 32, and the support member 32 can maintain close contact with the fixing member 37 when no external force is applied. When the magnetic adsorption support assembly 30 needs to be opened, the end of the support member 32 away from the first snap 50 is lifted and the support member 32 is rotated away from the first surface 371. At this time, the first snap 50 elastically deforms, and the free end 502 rises as the support member 32 rotates (i.e., rotates around the fixed end 501 in a direction away from the first surface 371). When the support member 32 is rotated until it forms an appropriate angle with the fixed member 37, a support effect can be achieved. When the magnetic adsorption support assembly 30 needs to be closed, the support member 32 is rotated in a direction toward the first surface 371 until it comes into close contact with the fixed member 37. At this time, the first snap 50 recovers its elastic deformation, and the support member 32 is fastened to the fixed member 37.

[0054] The magnetic support assembly 30 of this embodiment uses an axis-free rotation structure, and the first snap rotatably connects the fixing member 37 and the support member 32. When the magnetic support assembly 30 is closed, the overall thickness of the magnetic support assembly 30 is approximately equal to the thickness of the fixing member 37 and the support member 32. The free end 502 of the first snap 50 can rise when the magnetic support assembly 30 is opened, providing space for the support member 32 to rotate and suitable damping. Therefore, the magnetic support assembly 30 has the characteristics of being simpler in structure, lighter in weight, and thinner. Furthermore, the support member 32 can be further adapted for use as a magnetic stand, magnetic wireless charger, etc., thereby realizing multi-functional use of the magnetic support assembly 30 and making operation easier.

[0055] 16 to 19, the fixing member 37 is provided with a first engagement hole 373 penetrating the first surface 371 and the second surface 372. The free end 502 is located within the first engagement hole 373, and the first engagement groove 503 includes a first side wall 5031, a first bottom wall 5032, and a second side wall 5033. The first side wall 5031 is connected to the fixed end 501 and extends toward the support member 32 of the fixing member 37. The first bottom wall 5032 is connected to the end of the first side wall 5031 remote from the fixed end 501 and extends in a direction away from the fixed end 501 of the first side wall 5031. The second side wall 5033 is connected to the end of the first bottom wall 5032 remote from the first side wall 5031 and extends toward the second surface 372. The support member 32 is provided with an engagement segment 131 recessed toward the first engagement hole 373, and has a second engagement hole 132 between the engagement segment 131 and the second ring inner wall of the support member 32. The engagement segment 131 engages between the first side wall 5031 and the second side wall 5033, and the second side wall 5033 is inserted into the second engagement hole 132.

[0056] Figure 16 is a structural schematic diagram of the fixing member 37 and a partially enlarged schematic diagram of area B. As can be seen from the diagram, a first engagement hole 373 is provided between the first ring inner wall and the first ring outer wall of the fixing member 37, the free end 502 is located within the first engagement hole 373, and the first engagement groove 503 is formed by being surrounded by a first side wall 5031, a first bottom wall 5032 and a second side wall 5033, with the opening facing downward (facing away from the support member 32).

[0057] 19 is a schematic diagram of the structure of the support member 32. As can be seen from the drawing, the engagement segment 131 is recessed downward, and the second engagement hole 132 is located between the engagement segment 131 and the inner wall of the second ring. In FIGS. 14 and 15, the fixing member 37 and the support member 32 are assembled such that the second side wall 5033 of the first engagement groove 503 passes through the second engagement hole 132, thereby fastening the engagement segment 131 within the first engagement hole 373 with the first engagement groove 503. When the support member 32 rotates away from the first surface 371, the engagement segment 131 rises, and the second engagement hole 132 rotates accordingly until it is seated in the first bottom wall 5032. The width of the engagement segment 131 in the radial direction of the support member 32 is greater than the width of the second side wall from the first surface 371 to the second surface 372, for example, and the width of the first bottom wall 5032 in the radial direction of the fixing ring is greater than or equal to the thickness of the engagement segment 131 in the radial direction of the support member 32. Thus, when the support member 32 is opened, the free end 502 of the first snap 50 can be lifted. The depth of the engagement segment 131 recessed into the first engagement hole 373 is less than or equal to the thickness of the fixing member 37. The thickness of the first bottom wall 5032 from the first surface 371 to the second surface 372 is less than or equal to the thickness of the support member 32. Thus, when the support member 32 is erected, the thickness of the entire magnetic adsorption support assembly 30 is approximately equal to the sum of the thicknesses of the fixing member 37 and the support member 32.

[0058] 19 , the support member 32 further includes a first end 137 and a second end 138 located on opposite sides of the first opening 133. The support member 32 further includes a second snap 134 and a third snap 135. The second snap 134 is connected to the first end 137 and protrudes further toward the second opening 114 than the first end 137. The third snap 135 is connected to the second end 138 and protrudes further toward the second opening 114 than the second end 138. The support member 32 engages with the fixing member 37 by engaging into the second opening 114 via the second snap 134 and the third snap 135. This secures the support member 32 to the fixing member 37 in an unopened state, preventing unexpected deployment.

[0059] The magnetic adsorption support assembly 30 further includes an insulating portion 323. The insulating portion 323 includes a cover plate 323a and a bump structure 323b protruding toward the second opening 114. The cover plate 323a is installed within the first opening 133, and the bump structure 323b is fitted with the second snap 134 and the third snap 135, respectively. For example, in one embodiment, the second snap 134 and the third snap 135 have the same structure and are installed symmetrically. The second snap 134 specifically includes a third side wall 1341, a second bottom wall 1342, and a fourth side wall 1343. The third side wall 1341 is connected to the first end 137 and extends toward the second opening 114. The second bottom wall 1342 is connected to the side of the third side wall 1341 away from the first end 137 and extends toward the second end 138. The fourth side wall 1343 is connected to the second bottom wall 1342 on the side remote from the third side wall 1341 and extends in a direction away from the second opening 114 .

[0060] The bump structure 323b specifically includes a first bump and a second bump. The first bump fits between the second snap 134 and the third snap 135, and the second bump fits between the third sidewall 1341 and the fourth sidewall 1343. The third sidewall 1341 further includes, for example, a third opening 1344, and the second sidewall 1342 further includes a fourth opening 1345. The third opening 1344 communicates with the fourth opening 1345. The bump structure 323b further includes a third bump 1423, which is located on the side of the second bump away from the cover plate 323a and fits within the third opening 1344 and the fourth opening 1345.

[0061] The second snap 134 is surrounded by a third side wall 1341, a second bottom wall 1342, and a fourth side wall 1343 to form a groove, with the opening facing upward (away from the fixing member 37). The third opening 1344 and the fourth opening 1345 communicate to form an L-shaped hole. The structure of the third snap 135 can refer to the description of the second snap 134. The bump structure 323b further includes a bump similar to the second bump that fits into the groove of the third snap 135, and a bump similar to the third bump 1423 that fits into the opening in the third snap 135. The insulating portion 323 is fastened to the third snap 135 via the second snap 134 on the support member 32, and the support member 32 is also fastened to the third snap 135 via the second snap 134, resulting in a stable and aesthetically pleasing structure. The cover plate 323a may further be provided with, for example, a notch, so that the support member 32 can be easily opened.

[0062] In one embodiment, the fixing member 37 has a limiting slot 115 extending through the first surface 371 and the second surface 372 at the end rotatably connected to the support member 32 (i.e., the end closest to the first snap 50). The support member 32 is provided with a limiting member 136 that protrudes beyond the outer wall of the second ring, and the limiting member 136 is inserted into the limiting slot 115. As shown in FIGS. 17 and 18 , two elongated limiting slots 115 are provided on both sides of the first snap 50. When the support member 32 is in close contact with the fixing member 37, the limiting member 136 is inserted horizontally into the limiting slot 115. However, when the support member 32 is opened, the limiting member 136 is inserted obliquely into the limiting slot 115. When the support member 32 is opened to a predetermined angle, the end of the limiting member 136 farther from the inner wall of the second ring abuts the limiting slot 115, restricting the opening of the support member 32. Furthermore, the stability of the magnetic support assembly 30 is ensured.

[0063] Example 4 This embodiment is similar to the first embodiment, except that the magnetically attracting support assembly 30 has an annular structure and includes a first magnetically attracting member, a second magnetically attracting member, and a movable member.

[0064] 22, the protective shell with magnetic adsorption stand 100 includes a back plate 10 and a magnetic adsorption support assembly 30 connected to the back plate 10. The magnetic adsorption support assembly 30 is installed on the outer surface of the back plate 10 (the side away from the electronic device). The magnetic adsorption support assembly 30 has a folded state and a support state. In the folded state, the electronic device can be placed flat, and in the support state, the electronic device can be tilted at a predetermined angle. The user can switch the state of the magnetic adsorption support assembly 30 according to actual usage needs, such as switching to the folded state when charging or the support state when watching videos.

[0065] 23 and 24 , the magnetic support assembly 30 has an annular structure and includes a first magnetically attracting member 301, a second magnetically attracting member 302, and a movable member 303. The first magnetically attracting member 301 and the second magnetically attracting member 302 are fixedly connected to the backplate 10, and the movable member 303 is rotatably connected to the first magnetically attracting member 301 and the second magnetically attracting member 302. The state of the magnetic support assembly 30 is switched by rotating the movable member 303. In this embodiment, an annular receiving groove 11 is formed on the outer surface of the backplate 10, and the first magnetically attracting member 301 and the second magnetically attracting member 302 are fixedly installed in the receiving groove 11. When the magnetic support assembly 30 is switched to the folded state, the movable member 303 is flipped inward and inserted into the receiving groove 11. When the magnetic support assembly 30 is switched to the supporting state, the movable member 303 is flipped outward and extends out of the receiving groove 11.

[0066] Preferably, first magnetic attraction member 301, second magnetic attraction member 302, and movable member 303 are all arc-shaped and located on the same circle, with the inner diameter of the circle preferably being 40 to 56 mm, corresponding to the position, shape, size, etc. of the electronic device and the wireless charging module of the wireless charging dock. First magnetic attraction member 301, second magnetic attraction member 302, and movable member 303 are preferably magnetically attractable sheets, for example, iron plates or magnetic sheets, which improve the magnetic attraction effect with the wireless charging dock and prevent the electronic device from falling off the charging dock during charging, as well as improve the precision of positioning between the electronic device and the charging dock and ensure effective charging.

[0067] Preferably, the movable member 303 is approximately half a ring, and when it is turned outward, the user's fingers can be inserted into the internal semicircular space, so that when the magnetic adsorption support assembly 30 is switched to the folded state, the protective shell 100 for electronic devices of the present invention can be held by hand. The first magnetic adsorption member 301 and the second magnetic adsorption member 302 can jointly form the remaining half of the ring, and a first gap 304 is formed between them, so that the first magnetic adsorption member 301, the second magnetic adsorption member 302 and the movable member 303 as a whole form a non-closed ring structure, which avoids blocking the magnetic field and impairing the wireless charging effect.

[0068] In the illustrated embodiment, a first connecting member 305 and a second connecting member 306 are installed on the inner surface (the side facing the electronic device) of the backplate 10, and the first connecting member 305 and the second connecting member 306 are similarly sheet-like structures. The first connecting member 305 is riveted to the first magnetically attracting member 301 via a rivet, and the second connecting member 306 is riveted to the second magnetically attracting member 302 via a rivet, and corresponding holes for inserting the rivets are provided in the backplate 10. A second gap 307 is formed between the first connecting member 305 and the second connecting member 306, and the position of the second gap 307 directly faces the first gap 304.

[0069] As can be understood, the first connecting member 305, the second connecting member 306 and the first magnetic attraction member 301, the second magnetic attraction member 302 can be installed on the same side of the back plate 10, and the transition of the first connecting member 305, the second connecting member 306 can more closely combine the back plate 10 made of different materials with the first magnetic attraction member 301, the second magnetic attraction member 302. Also, the first magnetic attraction member 301, the second magnetic attraction member 302 can be connected to the back plate 10 by other methods, such as being integrally fitted into the back plate 10 by injection molding and fixed in the receiving groove 11 of the back plate 10 by interference fit.

[0070] Preferably, the first connecting member 305 and the second connecting member 306 are covered with a decorative member 308, which has a ring structure and a notch 470 formed at a position corresponding to the second gap 307. The decorative member 308 may be made of metal, plastic, wood, ceramic, or other materials, and can provide a decorative effect without interfering with wireless charging. Preferably, the inner surface of the backplate 10 is recessed to a predetermined depth to accommodate the first connecting member 305, the second connecting member 306, and the decorative member 308, so that the outer surface of the decorative member 308 is flush with the inner surface of the backplate 10, improving the appearance of the backplate 10 and reducing the overall thickness of the backplate 10.

[0071] Preferably, the first magnetically attracting member 301, the second magnetically attracting member 302, and the movable member 303 have substantially the same thickness, and in the folded state, the outer surfaces of the three are flush with each other, so that the entire outer surface of the magnetically attracting support assembly 30 is flat and can be attached to a charging dock. Preferably, in the folded state, the outer surfaces of the first magnetically attracting member 301, the second magnetically attracting member 302, and the movable member 303 are lower than the outer surface of the backplate 10 and are flush with the outer surface of the backplate 10, as shown in the figure. In use, the outer surfaces of the magnetically attracting support assembly 30 and the backplate 10 are simultaneously attached to the charging dock, improving the magnetic attraction effect.

[0072] In the illustrated embodiment, both ends of the movable member 303 are connected to the outer ends of the first magnetic attraction member 301 and the second magnetic attraction member 302 via damping kits 60, respectively, thereby forming a damping engagement so that when the movable member 303 is turned outward to a predetermined angle, it can be automatically maintained at that angle.

[0073] As shown in FIG. 25, the damping kit 60 includes a first damping member 601, a second damping member 602, and a rotating shaft 603 connecting the first damping member 601 and the second damping member 602 in series. One side of the first damping member 601 is riveted to the first magnetically attracting member 301 or the second magnetically attracting member 302, and the other side is wound around to form a first pivot hole 604. One side of the second damping member 54 is riveted to the movable member 303, and the other side is wound around to form a second pivot hole 605. Both ends of the rotating shaft 603 are inserted into the first pivot hole 604 and the second pivot hole 605, respectively, to form a damping engagement, which automatically fixes the movable member 303 after rotation due to frictional force and will not rotate automatically without an external force.

[0074] 26, the movable member 303 is fitted into the storage groove 11 of the back plate 10, and the entire protective shell 100 can be placed flat on a charging dock for charging, placed on a desk or the like to support an object, carried in a bag or pocket, or held in the hand. In the supporting state, as shown in FIG. 28, the movable member 303 is inverted and extends out of the storage groove 11, forming a triangular support together with the back plate 10, which can be used as a stand to keep the electronic device in an inclined position, making it convenient for the user to watch videos, etc.

[0075] Preferably, the outer surface of the movable member 303 is recessed at an intermediate position to form a handle portion 309, which allows the user to easily pull the movable member 303 to flip it outward and switch the magnetic adsorption support assembly 30 to the supporting state. Preferably, the rotation axis 603 is installed at an incline relative to the side edge of the back plate 10, approximately 45 degrees as shown in the figure. In this way, after the movable member 303 flips outward, its rotation axis and the side edge of the electronic device form a predetermined angle, so that the movable member 303 will not rotate even if the edge of the electronic device is lightly pressed, improving the stability of the support.

[0076] Example 5 This embodiment is similar to the first embodiment except that the magnetically attractive support assembly 30 has a polygonal structure.

[0077] 27 and 28, the magnetic attraction support assembly 30 has a polygonal structure. In this embodiment, the magnetic attraction support assembly has a regular hexagonal structure.

[0078] 29-31, in this embodiment, the support member 32 has a regular hexagonal structure, and the magnetically attracted member 34 includes a plurality of magnetic elements arranged in two arcs at intervals, with the ends of the two arcs spaced apart, ultimately forming a substantially circular shape. This prevents changes in the shape of the support member 32 from affecting the shape of the magnetically attracted member 34. Arranging the support member 32 in a polygonal shape provides a more stable support effect during support.

[0079] Example 6 This embodiment is similar to the first embodiment except that the first fixing member 37B also has a polygonal structure.

[0080] As shown in Figures 32 and 33, in this embodiment, the first fixing member 37B is also a regular hexagon, and when the magnetic adsorption support assembly 30 is in the stored state, the support member 32 is stacked on the first fixing member 37B. By installing the first fixing member 37B in the same shape and structure as the support member 32, the connection between the magnetic adsorption support assembly 30 and the backplate 10 can be made stronger.

[0081] Example 7 This embodiment is similar to the first embodiment except that a locking member 32 and a locking groove 323C are added to self-lock the magnetic attraction support assembly 30 when it is in the retracted state.

[0082] 34-36, the locking member 31 is provided on the back plate, and the locking groove 323C is provided on the magnetic support assembly 30. The back plate is further provided with a sliding groove 33, and the locking member 32 is slidable within the sliding groove 33 to lock or unlock with the locking groove 323C. The locking member 31 includes a main body 31B, sliding portions 31C located on both sides of the main body 31B, and a protrusion 31A located at one end of the main body. The sliding portion 31C is used to slidably connect with the sliding groove 33. When the main body 31B slides onto the magnetic support assembly 30, the protrusion 31A is inserted into the locking groove 323C to lock the magnetic support assembly 30 so that it cannot rotate relative to the back plate 10. When the magnetic support assembly 30 needs to be opened, the main body 31B is slid away from the magnetic support assembly 30, and the protrusion 31A and the locking groove 323C separate to unlock the assembly. The addition of self-locking can avoid unexpected deployment when the magnetic adsorption support assembly 30 does not need to be opened, improving the user experience.

[0083] Example 8 This embodiment is similar to the first embodiment except that the magnetic support assembly 30 is not rotatably connected to the backplate 10 .
