The support assembly is configured to be magnetically adsorbed, so that it has both a support function and a magnetic adsorption function, and the two functions do not affect each other, thereby solving the problem that the magnetic adsorption function and the stand function of the conventional protective shell affect each other.

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 electronic products and are common consumer goods in people's lives.

[0003] In order to facilitate charging and remove the constraints of wired charging, smartphones and tablet PCs equipped with an internal wireless charging unit have appeared, which realizes the purpose of wireless charging of the smartphone or tablet PC by an external wireless charger. Then, in order to ensure the stability of the 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 same magnetic ring assembly is also built into the external accessory, so that the smartphone or tablet PC and the external accessory can be easily attracted to each other through the magnetic ring assembly to achieve relative fixation, which greatly facilitates 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 adhesion force between the external accessory and the smartphone or tablet PC, resulting in a weak fixation between the external accessory and the smartphone or tablet PC. Therefore, it has become common practice to realize the magnetic adhesion fixation between the external accessory and the protective shell by incorporating a magnetic ring assembly into the protective shell.

[0005] For ordinary protective shells, this measure 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, for a protective shell with a stand, the built-in magnetic ring assembly affects the function of the stand to a certain extent, and since 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 position of the back plate of the protective shell, so that when the stand is standing, the center of gravity of the smartphone or tablet PC is biased, unstable, and easy to fall over. Similarly, the installation of the stand also affects the magnetic adsorption between the external accessories and the protective shell to a certain extent. 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 magnetic support assembly comprises a magnet or a material that is magnetically attracted to a magnet.

[0009] In one embodiment, the magnetically attractive support assembly includes a support member and a magnetically attractive member, the magnetically attractive member being fixedly or removably connected to the support member. Effect of the Invention

[0010] According to the protective shell with magnetic adsorption stand of the present application, the magnetic adsorption support assembly is installed 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. In a scene where support is required, the support can be realized by simply rotating the magnetic adsorption support assembly, and in a scene where the wireless charger needs to be fixed or the protective shell needs to be fixed to a vehicle stand, etc., the adsorption can be realized 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, thereby ensuring the stability of the support provided by the stand; and the support assembly is installed in a ring shape, thereby completely avoiding the wireless charging area of ​​the mobile phone and avoiding the impact of the installation of the stand on 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 terms used herein are for descriptive purposes only and should not be construed as limiting. As used herein, words such as "comprises," "has," "includes," 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 the element to one, but may include a plurality of elements.

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

[0015] The magnetic attraction support assembly 30 may be made of a magnet or a material that can be magnetically attracted to a magnet. For example, the magnetic attraction support assembly 30 may be made of iron, and in a scene where magnetic attraction is required, the magnetic attraction support assembly 30 can be attached to the accessory by simply aligning the magnetic attraction support assembly 30 with the corresponding accessory with a magnet.

[0016] In another embodiment, as shown in FIG. 2, the magnetic adsorption support assembly 30 includes a support member 32 and a magnetic adsorption member 34, and the magnetic adsorption member 34 is installed on the support member 32, thereby providing the magnetic adsorption support assembly 30 with a magnetic adsorption function. The magnetic adsorption member 34 may be fixedly connected to the support member 32 or detachably connected, and the magnetic adsorption member 34 and the support member 32 can be freely combined through the detachable connection, and can be combined when the magnetic adsorption function is required, and can be freely disassembled when the magnetic adsorption function is not required, thus realizing flexible use. Furthermore, when the electronic device is located in the housing chamber, the magnetic adsorption member is approximately aligned with the magnetic part of the electronic device. In this way, the magnetic adsorption 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 an accommodating portion for accommodating the magnetic attraction member 34 is provided on the support member 32. In this embodiment, the accommodating portion is an accommodating groove 36, and the magnetic attraction member 34 is also annular and is provided in the accommodating groove 36. In other embodiments, the accommodating portion may be an accommodating hole or other structure, as long as it can accommodate the magnetic attraction 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 opening segment 321B, the insulating portion 323 is provided on the opening segment 321B, and both ends of the insulating portion 323 are respectively 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 a beginning end and an end end of the annular segment 321A, the first end and the second end being spaced apart and combined to form an open segment 321B, and an insulating portion 323 is disposed within the open segment 321B, the insulating portion 323 being connected to the first end and the second end, thereby disposing 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 wood or ceramic.

[0018] Usually, in order to ensure the strength and service life of the support member 32, the support member 32 is generally made of metal or alloy material. When a metal foreign object is mixed into the energy transmission area of ​​the wireless charging system, due to the eddy current effect of the metal, a part of the electric energy will be consumed by the metal, which will have a certain impact on the power and efficiency of the wireless electric energy transmission, and more seriously, the eddy current effect of the metal will generate a large amount of heat, which will cause the wireless charger and electronic devices such as mobile phones to become hot, and further impair the charging efficiency. In particular, when the support ring 32 is annular, the annular support ring 32 will confine the eddy current within the ring, which will have a greater impact on the power and efficiency of the wireless electric energy transmission. The insulating part 323 is installed to form an opening for releasing the eddy current in the annular 323, thereby solving 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, the insulating portion 323 has a second side, and the first side and the second side are in the same arcuate plane, which can improve the feel.

[0020] Optionally, the magnetic attraction member 34 includes at least one of an iron plate and a magnet ring. In this embodiment, the magnetic attraction member 34 is a magnet ring, and the magnet ring may include a plurality of magnetic members arranged in an annular shape at intervals. In one embodiment, the magnetic attraction support assembly 30 further includes an adhesive layer 38, which is provided in the receiving groove 36, and the magnetic attraction member 34 is attached to the receiving groove 36 through the adhesive layer 38. Optionally, the adhesive layer 38 is formed by hardening at least one of a 3M adhesive and a liquid adhesive. In addition, the magnetic attraction support assembly 30 further includes a decorative layer 39, which is provided in the receiving groove 36 and covers the magnetic attraction member 32, can shield the magnetic attraction member 32, and improves the aesthetics of the 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 sequence in the length direction of the backplate 10, and the magnetic adhesion support assembly 30 includes a storage state, and when the magnetic adhesion support assembly 30 is in the storage state, the magnetic adhesion support assembly is located in the middle region 10B. In addition, the magnetic adhesion support assembly 30 further includes a support state, and when the magnetic adhesion support assembly 30 is in the support state, with the backplate 10 as the projection plane, when the opening angle of the magnetic adhesion support assembly is less than 90 degrees, the orthogonal projection of the magnetic adhesion support assembly 30 is located in the middle region 10B, and when the opening angle of the magnetic adhesion support assembly 30 is more than 90 degrees, the orthogonal projection of the magnetic adhesion support assembly 30 is located in the second region 10C. In another embodiment, when the rotating portion 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 fixed member 37, which is fixedly connected to the backplate 10, and the magnetic attraction support assembly 30 is rotatably connected to the fixed member 37 via a connecting portion 35. The fixed member 37 and the insulating portion 323 are located at opposite ends of the annular segment 321A.

[0023] In one embodiment, the insulating part 323 is disposed opposite the connecting part 35, thereby making it easier to rotate the magnetic adsorption support assembly 30 by the insulating part 323, 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°. In addition, a pull tab may be further disposed on the insulating part 323, so that the magnetic adsorption support assembly 30 can be easily opened during use.

[0024] In one embodiment, the backplate 10 is provided with a storage groove 11, the fixing member 37 is installed in the storage groove 11, and when the magnetic adsorption support assembly 30 is in a stored state, the support member 32 and the magnetic adsorption member 34 are both located in the storage groove 11. By providing the storage groove 11, when the magnetic adsorption support assembly 30 is in a stored state, the surface of the magnetic adsorption support assembly 30 is flush with the backplate 10, which can maximize the prevention of the surface of the backplate 10 becoming uneven due to the presence of the magnetic adsorption support assembly 30 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, the thickness of the magnetic attraction member 34 is 0.3mm-4mm, the optimal thickness is 0.7mm, the inner diameter of the magnetic attraction member is 40mm-52mm, the optimal inner diameter is 46mm, the outer diameter of the magnetic attraction member is 40mm-52mm, the optimal outer diameter is 54mm, the thickness of the magnetic attraction support assembly 30 is 1mm-5mm, the optimal thickness is 1.65mm, the inner diameter of the support member 32 is 38mm-50mm, the optimal inner diameter is 44mm, the outer diameter of the support member 32 is 50mm-62mm, the optimal outer diameter is 56.7mm. 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, the 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 backplate 10 is 77mm-97mm, or the distance between the center of the magnetic coupling area and the side edge of the backplate 10 is 40mm-52mm, which allows the magnetic adsorption support assembly to be located exactly at the approximate center position of the backplate, and when the protective shell is attached to the mobile phone, the magnetic adsorption support assembly can avoid the wireless charging area and will 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 is between 0 and 135°.

[0028] In one embodiment, the magnetic attraction member 34 includes a plurality of magnetic members, which are arranged in a circular or arc shape with intervals, as shown in Fig. 7. In the illustrated embodiment, the magnetic members are first arranged in an arc shape with intervals, and then four of the arc-shaped magnetic attraction members 30 are arranged in a circular shape with intervals, 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, so that the support member 32 can rotate relative to the back plate 10 or the side frame 20 to form a 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, the second fixing member 37C 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 rotating element 37A, so that the support member 32 can rotate relative to the back plate 10 or the side frame 20 to form a support. Furthermore, the second fixing member 37C is located on the inner side of the back plate 10 or the side frame 20. The first fixing member 37B and the second fixing member 37C are respectively provided on the inner side and the outer side of the back plate 10 or the side frame 20, so that the thickness of the entire fixing member 37 can be reduced to a certain extent, and the support member 32 can be flush with the back plate 10 or slightly protrude from the back plate 10 when in the stored state, so that the user experience can be improved, and the support member 32 being flush with the back plate 10 can be reduced to a certain extent in 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 similar to that of embodiment 1, except that the fixing member 37 is fixedly connected to the side frame 20, and an opening is provided in the magnetic adsorption member 34 to divide 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, etc., or a combination thereof. The protective shell with magnetic adsorption stand 100 includes a bottom wall, which has an opposite bottom wall inner surface and bottom wall outer surface, and the bottom wall inner surface side of the protective shell with magnetic adsorption stand 100 has a storage position for storing a mobile terminal. The mobile terminal can be various portable electronic devices such as a mobile phone or a tablet PC. In the present application, the mobile terminal is described as a mobile phone.

[0033] In some embodiments, the protective shell 100 with magnetic adsorption stand further includes at least one side wall extending from the bottom wall, which together with the bottom wall forms a storage space for storing the mobile terminal. In the embodiment shown, the protective shell 100 with magnetic adsorption stand 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. Fig. 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 is placed flat on a desk, the mobile phone is placed in a clothing pocket, or placed on a wireless charger to charge, 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 certain angle with the back plate 10, so that the mobile phone can be supported at a certain angle on a flat surface.

[0036] 11 shows the deployed position of the magnetic support assembly 30 functioning as a pull ring, where the magnetic support assembly rotates 180 degrees until it is flush or parallel with the backplate 10. For understanding, although two exemplary deployed positions are 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 back plate 10.

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

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

[0040] 14, a rotation stopper return mechanism formed between the pivot part 45 and the rotating shaft 43 is shown. The outer circumferential surface of the rotating shaft portion located within the pivot part 45 of the rotating shaft 43 has a first plane 431 and a first arcuate surface 432 connected to the first plane 431. A second plane 451 and a second arcuate surface 452 are provided on the inner wall surface of the pivot part 45. When the support member 32 is in the folded position, the first plane 431 of the rotating shaft 43 and the second plane 451 of the pivot part 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 part 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 part 45 are fixed relative to each other, thereby maintaining the support member 32 in the folded position. When the user manually operates the support member 32 and rotates the support member 32 in a direction away from the folded position (i.e., when rotating to the unfolded position), the rotating shaft part located inside the pivoting part 45 presses against the inner wall surface of the pivoting part 45 as it rotates, stretching the end of the side edge part of the riveted fixing member 37 and increasing the inner diameter of the pivoting part 45, thereby enabling rotation between the pivoting part 45 and the rotating shaft 43. When the user rotates the support member 32 from the unfolded position back to the folded position, the user manually rotates the support member 32 at the initial stage, and then the part of the fixing member 37 adjacent to its end simply elastically presses against the rotating shaft, thereby automatically returning the support member 32 to the folded position and maintaining it there.

[0042] 12 and 13, a connecting part 321 is provided at a portion of the support member 32 adjacent to the fixed member 37, and the connecting part 321 is fixedly connected to the rotating shaft 43, so that the connecting part 321 and the rotating shaft 43 do not rotate relative to each other. In the embodiment shown, the connecting part 321 includes at least one connecting pipe 322, which is fitted to the rotating shaft 43, and a damping material is installed between the connecting pipe 322 and the rotating shaft 43 to increase the 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 cannot rotate relative to each other, and therefore the support member 32 cannot rotate relative to the rotating shaft 43. In the embodiment shown, the connection portion 321 is provided with two connection pipes 322, which are located on both sides of the fixed member 37 and fitted to both ends of the rotating shaft 43, and the damping material is the damping pipe 323, with one damping pipe 323 interposed between each connection 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 intimate 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 in 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 outer side 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 on the side away from the mounting portion 42.

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

[0045] The magnetic attraction member 34 is installed on the annular outer surface 325, and the mobile terminal mounted in the protective shell 100 is fixed to another object by magnetic attraction. In one application scenario, the mobile terminal is fixed to a wireless charger by magnetic attraction and wireless charging is performed. In general, a wireless charger is provided with a transmitting coil of the charger and a magnet located on the outer periphery of the transmitting coil, and a receiving coil for wireless charging is installed inside a mobile terminal such as a mobile phone. 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 located on the outer periphery of the receiving coil of the mobile phone mounted in the protective shell 100 in the radial direction. When wireless charging is performed, the receiving coil of the mobile phone faces the transmitting coil of the wireless charger, and the magnetic attraction member 34 faces the magnet of the wireless charger, and the mobile phone is positioned on the wireless charger by the magnetic attraction. By providing the above-mentioned notch 341, on the premise that the magnetic attraction member 34 completes the function of magnetic positioning, it is possible to effectively reduce disturbance induction and heat generation during wireless charging, thereby avoiding or reducing the impact of the magnetic attraction member 34 on wireless charging.

[0046] In the embodiment shown, the annular outer surface 325 is provided with a mounting groove 326, and the magnetic attraction member 34 is mounted in the mounting groove 326. The outer surface of the magnetic attraction member 34 does not exceed the annular outer surface 325, and may be lower than or flush with the annular outer surface 325. The magnetic attraction member 34 is, for example, adhesively fixed in the mounting groove 326. The magnetic attraction member 34 is mounted in the mounting groove 326, and the outer surface of the magnetic attraction member 34 does not exceed the annular outer surface 325. Therefore, the installation of the magnetic attraction 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 the decrease in charging efficiency caused by the increase in distance.

[0047] Although the illustrated embodiment shows an example of two magnetically attractive members 34, in other embodiments, one long magnetically permeable member may be provided on the annular outer surface 325, and the notch is formed between two circumferential ends of the one long 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 Figures 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 facing the first surface 371. The first snap 50 has a fixed end 501 and a free end 502 facing each other, the fixed end 501 is connected to the fixing member 37, the free end 502 is located on the side of the fixed end 501 close to the first ring inner wall of the fixing member 37, and is elastically rotatable around the fixed end 501 to approach the first surface 371 or move away from the first surface 371. A first engagement groove 503 is provided 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, the magnetic attachment support assembly 30 is in a closed state, and the support member 32 is substantially overlapped with the fixed member 37. As shown in FIG. 17, the magnetic attachment support assembly 30 is in an open state, and the support member 32 rotates around the fixed member 37 and forms a predetermined angle with the fixed member 37 to support an electronic device. The support member 32 has a second ring inner wall and a second ring outer wall facing each other. As shown in FIG. 18, which is an exploded structural schematic diagram of FIG. 17, the support member 32 is provided with a first opening 133 that communicates the second ring inner wall and the second ring outer wall. 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 realizing the rotation of the support member 32 so as to approach the first surface 371 or move away from the first surface 371 relative to the fixed 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, the above-mentioned first snap 50 is merely an illustrative example of one embodiment of the present invention, and the rotatable connection between the support member 32 and the fixed member 37 may be realized by a connection using a shaft pin, and the present embodiment is not limited thereto. The fixed member 37 and the support member 32 may be, for example, an annular sheet structure as a whole, and the fixed member 37 may be a ring of other shapes instead of an annular shape, and the size of the ring of the support member 32 may be compatible with the size of a commercially available Magsafe magnetic adsorption ring, and the support member 32 may be, for example, a magnetically adsorbable metal ring such as an iron ring, so that the magnetic adsorption support assembly 30 can be compatible with the Magsafe magnetic adsorption vehicle stand or the Magsafe wireless charger, and has a relatively good magnetic adsorption effect. In addition, the support member 32 is provided with the first opening 133, so that the support member 32 does not form a complete metal ring, and when used in combination with the magnetic adsorption wireless charger, the heat generation can be reduced and the charging effect can be improved.

[0052] In one embodiment, as shown in Figs. 17-18, the magnetic adsorption support assembly 30 further includes an insulating part 323, for example, installed in the first opening 133. The charging effect can be ensured while the aesthetics and stability of the electronic device stand can be ensured. The fixing member 37 may be a metal iron ring or a non-metallic material. When the fixing member 37 is made of a magnetically adsorbable metallic material such as an iron ring, it is not necessary to use an adhesive to attach the fixing member 37 to the back of the electronic device when a magnetic member is installed on the back of the electronic device itself, and the fixing member 37 can be directly attached to the back of the electronic device and used. When the magnetic adsorption support assembly 30 is not required to be used, it can be removed at any time, making the operation simple. Similarly, as shown in Figs. 18 and 19, when the fixing member 37 is made of a metallic material, the fixing member 37 further includes a second opening 114 corresponding to the position of the first opening 133, which also improves the charging effect. The first snap 50 may be made of a metallic elastic plate or other material having elastic deformation characteristics. The first snap 50 may be installed integrally 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 the magnetic adsorption support assembly 30 is used, the second surface 372 of the fixing member 37 can be attached to the back surface of the electronic device or the back surface of the protective shell. In the closed state, the supporting member 32 is stacked on the first surface of the fixing member 37 and is almost overlapped with the fixing member 37. At this time, the free end 502 of the first snap 50 fastens the supporting member 32, and the supporting member 32 can maintain a state of being in 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 in a direction away from the first surface 371, at which time the first snap 50 is elastically deformed, and the free end 502 rises with the rotation of the support member 32 (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 a suitable angle with the fixed member 37, the support effect can be realized. When the magnetic adsorption support assembly 30 needs to be closed, the support member 32 is rotated in a direction approaching the first surface 371 until it is in close contact with the fixed member 37, at which 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 realizes the rotatable connection between the fixing member 37 and the support member 32. When the magnetic support assembly 30 is closed, the thickness of the magnetic support assembly 30 is approximately equal to the thickness of the two sheets 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, and can provide space and suitable damping for the support member 32 to rotate. Therefore, the magnetic support assembly 30 has the characteristics of being simpler in structure, lighter and thinner, and the support member 32 can be further adapted to the use scenes of magnetic adsorption stand, magnetic adsorption wireless charger, etc., thereby realizing the multi-functional use of the magnetic support assembly 30 and making the operation easier.

[0055] More specifically, as shown in Figs. 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 in 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 to the side of the fixing member 37 close to the support member 32. 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 in a direction approaching 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 a 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 figure, 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, and the opening faces downward (facing the side away from the support member 32).

[0057] 19 is a structural schematic diagram of the support member 32. As can be seen from the figure, the engagement segment 131 is recessed downward, and there is a second engagement hole 132 between the engagement segment 131 and the inner wall of the second ring. In FIG. 14 and FIG. 15, the assembly method of the fixing member 37 and the support member 32 is that the second side wall 5033 of the first engagement groove 503 penetrates the second engagement hole 132, so that the engagement segment 131 is clamped in the first engagement hole 373 by the first engagement groove 503. When the support member 32 rotates away from the first surface 371, the engagement segment 131 stands up, 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, for example, larger than the width of the second side wall along the first surface 371 to the second surface 372, and the width of the first bottom wall 5032 in the radial direction of the fixing ring is equal to or larger than the thickness of the engagement segment 131 in the radial direction of the support member 32, thus allowing the free end 502 of the first snap 50 to be lifted when the support member 32 is opened. The depth of the engagement segment 131 recessed into the first engagement hole 373 is equal to or smaller than the thickness of the fixing member 37. The thickness of the first bottom wall 5032 along the first surface 371 to the second surface 372 is equal to or smaller than the thickness of the support member 32. Thus, when the support member 32 stands up, the thickness of the entire magnetic adhesion 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, and the second snap 134 is connected to the first end 137 and protrudes toward the second opening 114 beyond the first end 137. The third snap 135 is connected to the second end 138 and protrudes toward the second opening 114 beyond the second end 138. The support member 32 engages with the fixing member 37 by engaging in the second opening 114 via the second snap 134 and the third snap 135. This allows the support member 32 to be fixed to the fixing member 37 in an unopened state, preventing unexpected deployment.

[0059] Further, the magnetic adsorption support assembly 30 further includes an insulating part 323, the insulating part 323 includes a cover plate 323a and a bump structure 323b protruding in a direction approaching the second opening 114, the cover plate 323a is installed in the first opening 133, and the bump structure 323b is respectively fitted with the second snap 134 and the third snap 135. 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 in a direction approaching 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 in a direction approaching 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] Specifically, the bump structure 323b 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 side wall 1341 and the fourth side wall 1343. The third side wall 1341 further includes, for example, a third opening 1344, and the second side wall 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 disposed on the side of the second bump away from the cover plate 323a and fits into the third opening 1344 and the fourth opening 1345.

[0061] The second snap 134 is surrounded by the third side wall 1341, the second bottom wall 1342 and the fourth side wall 1343 to form a groove shape, and the opening faces upward (facing 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, and the bump structure 323b further includes a bump similar to the second bump, for example, which fits into the groove shape of the third snap 135, and further includes a bump similar to the third bump 1423, for example, which fits into the opening in the third snap 135. The insulating part 323 is fastened to the third snap 135 through the second snap 134 on the support member 32, and the support member 32 is also fastened to the third snap 135 through the second snap 134, making the structure stable and beautiful. 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 fixed member 37 is provided with a limiting slot 115 penetrating the first surface 371 and the second surface 372 at the end rotatably connected to the support member 32 (i.e., the end adjacent to the first snap 50). The support member 32 is provided with a limiting member 136 protruding beyond the outer wall of the second ring, and the limiting member 136 is inserted into the limiting slot 115. As shown in Figures 17 and 18, two long limiting slots 115 are provided on both sides of the first snap 50, respectively. When the support member 32 is in close contact with the fixed member 37, the limiting member 136 is inserted into the limiting slot 115 horizontally. However, when the support member 32 is opened, the limiting member 136 is inserted into the limiting slot 115 obliquely. When the support member 32 is opened to a predetermined angle, the end of the limiting member 136 away from the inner wall of the second ring abuts against the limiting slot 115 to limit the opening degree of the support member 32. It also ensures the stability of the magnetic support assembly 30 when in use.

[0063] Example 4 This embodiment is similar to embodiment 1, except that the magnetic attraction support assembly 30 has an annular structure and includes a first magnetic attraction member, a second magnetic attraction member and a movable member.

[0064] As shown in FIG. 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, and the magnetic adsorption support assembly 30 is installed on the outer surface (the side away from the electronic device) of the back plate 10. The magnetic adsorption support assembly 30 includes a folded state and a support state, in which the electronic device can be placed flat in the folded state, and in which the electronic device can be tilted at a certain angle in the support state. The user can switch the state of the magnetic adsorption support assembly 30 according to the actual usage needs, such as switching to the folded state when charging or switching to the support state when watching a video.

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

[0066] Preferably, the first magnetic attraction member 301, the second magnetic attraction member 302 and the movable member 303 are all arc-shaped and located on the same ring, and the inner diameter of the ring is preferably 40-56 mm, corresponding to the position, shape, size, etc. of the electronic device and the wireless charging module of the wireless charging dock. The first magnetic attraction member 301, the second magnetic attraction member 302 and the movable member 303 are preferably magnetically attractable sheets, for example, all of which are iron plates or magnetic sheets, which can 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 high-precision positioning between the electronic device and the charging dock and ensure the charging effect.

[0067] Preferably, the movable member 303 is approximately a half ring, and when it is flipped 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 also be held by hand, and the first magnetic adsorption member 301 and the second magnetic adsorption member 302 can jointly form the remaining half 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, thereby avoiding 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, 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 through a rivet, the second connecting member 306 is riveted to the second magnetically attracting member 302 through a rivet, and the backplate 10 is provided with corresponding drilling holes for inserting the rivets. 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 is directly opposite to 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 backplate 10, and the transition of the first connecting member 305 and the second connecting member 306 can more closely combine the backplate 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 backplate 10 in other ways, such as being integrally fitted into the backplate 10 by injection molding and fixed into the receiving groove 11 of the backplate 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, etc., and can provide a decorative effect without interfering with wireless charging. Preferably, the inner surface of the backplate 10 is recessed to a certain 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 magnetic attraction member 301, the second magnetic attraction 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 outer surface of the entire magnetic attraction support assembly 30 is flat and can be closely attached to the charging dock. Preferably, in the folded state, the outer surfaces of the first magnetic attraction member 301, the second magnetic attraction 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, so that the outer surfaces of the magnetic attraction support assembly 30 and the backplate 10 are closely attached to the charging dock at the same time during use, 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, and when the movable member 303 is rotated outward to a predetermined angle, it can be automatically maintained at the 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 connected to the first magnetic attraction member 301 or the second magnetic attraction member 302 by riveting, and the other side is wound to form a first pivot hole 604, one side of the second damping member 54 is connected to the movable member 303 by riveting, and the other side is wound to form a second pivot hole 605, and 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 fit, so that the movable member 303 is automatically fixed after rotating by frictional force, and will not automatically rotate without the action of an external force.

[0074] In the folded state, as shown in Fig. 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, or placed on a desk or the like for supporting an object, or carried in a bag or pocket, or held by hand. In the supported 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 state, and is convenient for users to watch videos, etc.

[0075] Preferably, the middle position of the outer surface of the movable member 303 is recessed 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 inclined to the side edge of the back plate 10, and is inclined at about 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 certain 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 magnetic 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 magnetic attraction member 34 includes a plurality of magnetic members arranged in two arcs at intervals, with both ends of the two arcs spaced apart from each other, ultimately forming a substantially annular shape. This ensures that changes in the shape of the support member 32 do not affect the shape of the magnetic attraction member 34. By arranging the support member 32 in a polygonal shape, a more stable support effect can be provided 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 support assembly 30 in the stored state.

[0082] As shown in FIGS. 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 can slide in the sliding groove 33 to lock or unlock with the locking groove 323C. The locking member 31 includes a main body 31B, sliding parts 31C located on both sides of the main body 31B, and a protrusion 31A located at one end of the main body, and the sliding part 31C is used for slidably connecting with the sliding groove 33. When the main body 31B slides toward 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 it is necessary to open the magnetic support assembly 30, the main body 31B is slid away from the magnetic support assembly 30, and the protrusion 31A and the locking groove 323C are separated to unlock. 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 embodiment 1, except that the magnetic support assembly 30 is not rotatably connected to the backplate 10.

[0084] As shown in Figures 37 and 38, the connecting member 28i is fixedly or detachably connected to the backplate 10, at least a portion of the connecting member 28i is made of a flexible material such as rubber, flexible plastic, silicone resin, etc., the connecting member 28i is expandable and contractible relative to the backplate 10, and the magnetically attractive member 32 is connected to the connecting member 28i, and the magnetically attractive member 32 is movable away from or toward the backplate via the connecting member 28a.

[0085] The connecting member 28i is accommodated in the accommodation space 1123a. The connecting member 28i includes a first connecting portion 281i fixedly or detachably connected to the bottom wall of the accommodation space 1123a, a second connecting portion 282a connected to the first connecting portion 282i, and a third connecting portion 283i connected to the second connecting portion 282i. The size of the first connecting portion 281i and the third connecting portion 283i is larger than the size of the second connecting portion 282i. The second connecting portion 282i is made of a flexible material, and the connecting member 28i may be in an expanded or contracted state. The first connecting portion 281i and the third connecting portion 283i may be made of a flexible material.

[0086] The support member 32 is fitted around the magnetic attraction member 34, and the magnetic attraction member 34 is fitted around the third connecting portion 283i. When the second connecting portion 282i expands, the magnetic attraction member 34 moves accordingly, thereby supporting the protective shell. When the second connecting portion 282i contracts, the connecting member 28i can be at least partially accommodated in the accommodating space 1123a, and the magnetic attraction member 34 is at least partially accommodated in the accommodating space 1123a or disposed outside the accommodating space 1123a.
