[0019] 5. The present invention provides a magnetic bracket assembly in which a second through hole is provided for the user's finger to pass through and hold the electronic device, and the second through hole does not cover the first through hole when the ring is folded and stored, thereby avoiding problems such as dust accumulation.

For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0041] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0042] Please see Figure 1 , Figure 2 and Figure 3 The first embodiment of this utility model provides a magnetic support assembly, including a base 1, a ring 2, a limiting member 3, and a mounting member 4 rotatably connected. A first through hole 11 is opened in the center of the base 1, making the base 1 annular. The base 1 and the ring 2 are rotatably connected. The mounting member 4 is located in the first through hole 11 and fixed to the external plane. A gear 12 is provided on the inner wall of the first through hole 11. The limiting member 3 is provided in the first through hole 11 and fixed by the mounting member 4. The end of the limiting member 3 elastically abuts against the gear 12. The limiting member 3 and the mounting member 4 move synchronously relative to the base 1. The base 1 and the ring 2 are magnetic.

[0043] Understandably, the limiting member 3 is installed inside the first through hole 11 and elastically resists the gear 12. When the chassis 1 rotates, the limiting member 3 slides between the gears 12. The elastic resisting force applied to the gear 12 by the end of the limiting member 3 enhances the stability of the adjustment process, and the vibration echo generated when the limiting member 3 transitions between different teeth of the gear 12 provides the user with clear tactile feedback for adjustment. At the same time, the chassis 1 drives the ring 2 to move synchronously, so that the ring 2 can rotate 360° and flip the ring 2 off the chassis 1, so that the ring 2 is in the desired position. The user can hold the electronic device through the ring 2, or put the ring... 2 serves as a support to place the electronic device on an external plane; the mounting component 4 is used to connect the magnetic bracket assembly to the outside, while the chassis 1 is magnetic, allowing the magnetic bracket assembly to be connected to the electronic device or its housing for easy installation and disassembly; the magnetism of the ring 2 further enhances the stability of the connection between the magnetic bracket assembly and the electronic device or its housing; in summary, the first embodiment provided by this utility model improves the overall structural stability through the cooperative structure of the gear 12 and the limiting component 3, while the magnetism of the chassis 1 and the ring 2 enables the magnetic bracket assembly to be easily connected and disassembled with the electronic device or its housing.

[0044] Please see Figure 1 , Figure 2 and Figure 4 The magnetic bracket assembly also includes a mounting plate 5, which is located in the first through hole 11 and connected to the mounting member 4. A receiving space is provided between the mounting plate 5 and the mounting member 4, and the limiting member 3 is located in the receiving space. The receiving space is used to accommodate the limiting member 3 and to provide space for the elastic sliding of the limiting member 3 when it moves between the gears 12.

[0045] Optionally, the mounting plate 5 can be made of metal or plastic. The metal mounting plate 5 has better heat dissipation, while the plastic mounting plate 5 is lighter. Users can choose flexibly according to their needs.

[0046] Furthermore, one end of the mounting component 4 is connected to the mounting plate 5, and the other end is connected to an external plane, such as the casing of an electronic device, thereby improving the stability of the magnetic bracket assembly during use.

[0047] Furthermore, several first heat dissipation holes 51 are formed on the edge of the mounting plate 5. The first heat dissipation holes 51 help the mounting plate 5 dissipate heat, allowing the heat generated by the electronic device to be transferred to the air through the first heat dissipation holes 51, thereby improving heat dissipation efficiency and reducing the impact of the mounting plate 5 on the heat dissipation of the electronic device.

[0048] Furthermore, the magnetic bracket assembly also includes an elastic element 7. The mounting plate 5 has a sliding groove 52 on one side of the accommodating space. The limiting element 3 is located in the sliding groove 52 and is connected to the elastic element 7 at the end away from the gear 12 and abuts against the inner wall of the sliding groove 52. When the limiting element 3 slides in the sliding groove 52, it cooperates with the elastic element 7 to realize movement between the gears 12.

[0049] Furthermore, a protrusion 521 is provided at the opening of the sliding groove 52, and a second step structure 31 is provided at the end where the limiting member 3 abuts against the gear 12. The second step structure 31 engages with the protrusion 521, thereby ensuring that the second step structure 31 remains within the sliding groove 52, preventing the limiting member 3 from disengaging from the sliding groove 52.

[0050] Understandably, the elastic element 7 helps the limiting element 3 to elastically resist the relative movement with the gear 12. During the process of elastic deformation, the limiting element 3 slides in the sliding groove 52 under the elastic force of the elastic element 7. The sliding groove 52 restricts the range of movement of the limiting element 3 and avoids the limiting element 3 from dislodging during the movement and affecting the resisting relationship with the gear 12.

[0051] Alternatively, the sliding groove 52 can also be provided on the mounting part 4.

[0052] Furthermore, the end of the limiting member 3 that abuts against the gear 12 has a sharp structure, and a rounded chamfer is provided at the end of the sharp structure, so that the limiting member 3 can fit with the gear 12 and smoothly transition between the gears 12, reducing the wear of the two elastically abutting parties during the sliding process and extending the service life of the magnetic support assembly.

[0053] Furthermore, when the limiting member 3 is placed in the sliding groove 52, it is perpendicular to the tangent of the point where the limiting member 3 abuts against the gear 12, so as to reduce the wear when sliding on the gear 12 and extend the service life of the component.

[0054] It should be noted that the mounting component 4 is arranged parallel to the mounting plate 5, which facilitates the setting of the sliding groove 52 in the accommodating space.

[0055] In this embodiment, the mounting plate 5 is provided with a plurality of mounting posts 53 on one side of the accommodating space, and the mounting component 4 is provided with the same number of first mounting holes 41. The mounting posts 53 are connected to the first mounting holes 41 to achieve parallel arrangement of the mounting component 4 and the mounting plate 5.

[0056] Optionally, the positions of mounting post 53 and first mounting hole 41 can be interchanged.

[0057] Furthermore, the end of the sliding groove 52 away from the gear 12 is closed, and one end of the elastic member 7 abuts against the closed end to limit the sliding range of the limiting member 3 and prevent the limiting member 3 from deviating from the set path during the sliding process, thus affecting the movement of the limiting member 3.

[0058] It should be noted that a second through hole 21 is provided in the center of the ring 2. The second through hole 21 corresponds to the first through hole 11 and its area is not smaller than that of the first through hole 11. The second through hole 21 allows the user's fingers to pass through and hold the electronic device. When the ring 2 is folded and stored, the second through hole 21 will not cover the first through hole 11, thereby avoiding problems such as dust accumulation.

[0059] Please see Figure 1 and Figure 3 The first through hole 11 has a first step structure 14 on its edge. When the ring 2 is folded and stored, the edge of the second through hole 21 engages with the first step structure 14 to improve the stability of the ring 2 when it is folded.

[0060] Please see Figure 1 , Figure 2 and Figure 4 Furthermore, the magnetic bracket assembly also includes a connector 6, through which the ring 2 and the base 1 are rotatably connected so that the ring 2 can be rotated to the position required by the user, and the ring 2 can be folded and stored away to save space when not in use.

[0061] Furthermore, a connection hole 13 is provided on the chassis 1, and the connector 6 is located in the connection hole 13 and connected to the ring 2, so that the chassis 1 will not dislodge when the ring 2 is flipped, and the position can be maintained stably. The user can hold the electronic device stably through the ring 2, or the ring 2 can provide stable support for the magnetic bracket assembly.

[0062] It should be noted that the chassis 1 is connected to the ring 2 in a certain area through the connecting hole 13 via the connector 6, so as to maintain the stability of the overall structure of the chassis 1 when rotating.

[0063] Furthermore, a notch 22 is provided on the side of the ring 2 that is away from the connector 6 and close to the chassis 1. When the ring 2 is folded on the chassis 1, the user can flip the ring 2 out through the notch 22 and rotate it.

[0064] Preferably, at least two limiting members 3 are provided, and the distance between the limiting members 3 is equal when they abut against the gear 12. Multiple limiting members 3 can abut against the gear 12 more stably, making the rotation process of the chassis 1 more stable. Furthermore, the limiting members 3 are evenly distributed on the gear 12 so that the gear 12 can be evenly stressed when it rotates, thus extending the service life of the gear 12.

[0065] In this embodiment, two limiting members 3 are connected to the gear 12. The two limiting members 3 are symmetrically arranged and are engaged and supported at both ends of the gear 12 to improve the stability of the gear 12 rotation.

[0066] Furthermore, a base plate 8 is provided on the side of the chassis 1 facing away from the ring 2 to protect the bottom surface of the chassis 1 when the chassis 1 comes into contact with the external plane, prevent the surface of the chassis 1 from being scratched, and extend the service life of the chassis 1.

[0067] Furthermore, the film 8 is arc-shaped and fixed to the edge of the chassis 1.

[0068] Preferably, the substrate 8 is made of silicone, which allows the substrate 8 to provide more cushioning for the chassis 1 and reduce the impact of external shocks on the chassis 1.

[0069] Furthermore, a heat sink 9 is provided on the side of the mounting plate 5 near the mounting component 4. The heat sink 9 is located in the first through hole 11 and is disposed between the mounting plate 5 and the mounting component 4 to achieve the function of heat dissipation for the electronic equipment part in the first through hole 11.

[0070] Preferably, the heat sink 9 is made of graphene dustproof material, which has excellent heat dissipation function and is thin and light, maintaining the lightweight characteristics of the overall structure.

[0071] In summary, please refer to Figures 1 to 4 The working principle of the magnetic support assembly provided in the first embodiment of this utility model is as follows:

[0072] The magnetic bracket assembly magnetically connects to the electronic device or casing via the magnetism of the base 1 and the ring 2, facilitating disassembly and improving stability during use. When using the magnetic bracket assembly, the limiting member 3 slides on the gear 12, enabling the base 1 to rotate 360°, ensuring stable rotation and providing clear tactile feedback. After rotating the base 1 to the desired position, the gear 12 engages with the limiting members 3 at both ends to enhance stability and prevent dislocation. The ring 2 is flipped off the base 1 via the notch 22 and rotated to the desired orientation and position, allowing the user to grip the electronic device. During operation, the heat sink 9 and the first heat dissipation hole 51 both contribute to heat dissipation, minimizing the impact of the magnetic bracket assembly on the electronic device.

[0073] Please see Figure 4 , Figure 5 and Figure 6 The second embodiment of this utility model provides a protective shell, including the magnetic bracket assembly provided in the first embodiment above, and also includes a housing 10. The magnetic bracket assembly is magnetically connected to the housing 10, which facilitates the installation or removal of the magnetic bracket assembly at any time.

[0074] Furthermore, a mounting groove 101 is provided on the housing 10, and the chassis 1 is at least partially embedded in the mounting groove 101.

[0075] Understandably, the chassis 1 is magnetically connected to the mounting groove 101, which allows the mounting groove 101 to restrict the position of the chassis 1 magnetically attached to the housing 10 during installation, preventing the chassis 1 from shifting and causing the magnetic bracket assembly to become unstable. During disassembly, the user can remove the chassis 1 through the part of the chassis 1 that is not embedded in the mounting groove 101.

[0076] It should be noted that you should refer to [link / reference]. Figure 4 , Figure 6 and Figure 7 An annular groove 1011 is provided on the side wall of the mounting groove 101, and an annular convex rail 15 is correspondingly provided on the side wall of the chassis 1. When the chassis 1 rotates, the annular convex rail 15 slides in the annular groove 1011. The structure of the two engaging with each other limits the axial movement of the chassis 1, reducing the risk of the chassis 1 detaching from the mounting groove 101.

[0077] Please see Figure 4 , Figure 5 and Figure 6 A limiting hole 102 is provided in the mounting groove 101. The mounting part 4 and the mounting plate 5 are respectively connected to the two sides of the limiting hole 102. The limiting part 3 is located in the limiting hole 102, and the end of the limiting part 3 abuts against the side wall of the limiting hole 102.

[0078] Understandably, the housing 10 is further securely connected to the magnetic support assembly through the limiting hole 102, and the movement range of the limiting member 3 is limited by the limiting hole 102. Compared with the solution provided in the first embodiment, this embodiment does not provide a sliding groove 52, which makes the structure simpler and reduces costs.

[0079] Furthermore, a second mounting hole 104 is provided in the mounting groove 101. The second mounting hole 104 is connected to the mounting post 53 to improve the stability of the connection between the magnetic bracket assembly and the housing 10.

[0080] It should be noted that the mounting component 4 and the mounting plate 5 are located at both ends of the limiting hole 102, and the second mounting hole 104 is opened on both sides of the limiting hole 102. The mounting post 53 is connected to the second mounting hole 104 and the first mounting hole 41 in sequence, so that the structure of the mounting component 4 and the mounting plate 5 connected to both sides of the housing 10 is more stable.

[0081] Furthermore, a second heat dissipation hole 103 is provided on the housing 10, and the position of the second heat dissipation hole 103 corresponds to that of the first heat dissipation hole 51. The second heat dissipation hole 103 is connected to the first heat dissipation hole 51, and the first heat dissipation hole 51 and the second heat dissipation hole 103 can better perform their heat dissipation functions.

[0082] Furthermore, the second heat dissipation hole 103 is connected to the limiting hole 102 to simplify the process and reduce costs.

[0083] In summary, please refer to Figures 1 to 6The working principle of the protective shell provided in the second embodiment of this utility model is as follows:

[0084] The magnetism of the chassis 1 and the ring 2 enables the magnetic bracket assembly to be stably magnetically attached to the housing 10, and the chassis 1 is positioned by the mounting groove 101. The mounting post 53 cooperates with the first mounting hole 41 and the second mounting hole 104 respectively to further improve the stability of the magnetic bracket assembly. When the limiting member 3 slides on the gear 12, the end away from the gear 12 abuts against the side wall of the limiting hole 102. The limiting hole 102 restricts the range of motion of the limiting member 3 to ensure the stable rotation of the chassis 1.

[0085] Compared with the prior art, the magnetic bracket assembly and protective shell provided by this utility model have the following advantages:

[0086] 1. This utility model provides a magnetic support assembly that enhances the overall structural stability through the cooperation of gears and limiting components, while also utilizing the magnetism of the chassis and the ring.

Users can hold the electronic device with the ring or use it as a support to place the electronic device on an external surface. The chassis is magnetic, allowing the magnetic support assembly to be connected to the electronic device or its casing for easy installation and removal.
