[0046] Please combine Figure 1 - Figure 3 The utility model provides a magnetic bracket 1, comprising a base plate 10, a support plate 11, a connecting member 13 and a folding member 12, the folding member 12 connects the base plate 10 and the support plate 11 and can be unfolded and folded, one end of the connecting member 13 is connected to the support plate 11, and the other end is connected to the base plate 10; the folding member 12 comprises a first folding plate 121, a second folding plate 122 and a third folding plate 123 connected in sequence, a side of the base plate 10 facing the support plate 11 is provided with a folding groove 101 corresponding to the first folding plate 121 and the second folding plate 122, and the third folding plate 123 is connected to the support plate 11; wherein, when the folding member 12 is in a stored state, the first folding plate 121 and the second folding plate 122 are folded and stored in the folding groove 101, and when the folding member 12 is in an unfolded state, the second folding plate 122 can be folded relative to the base plate 10 to the outside of the folding groove 101 and stacked on the first folding plate 121, so that the connecting member 13, the support plate 11 and the base plate 10 form a triangular structure.

[0047] Specifically, the folding piece 12 is made of flexible material and can be folded and unfolded. The first folding plate 121 in the folding piece 12 is connected to the substrate 10, the third folding plate 123 is connected to the support plate 11, and the second folding plate 122 is connected to the third folding plate 123, thereby realizing the connection between the support plate 11 and the substrate 10. Therefore, the support plate 11 can change the support angle, position, direction and state as the folding and unfolding of the folding piece 12; the first folding plate 121, the second folding plate 122 and the third folding plate 123 can be rectangular or square plate structures, which are easy to fold and store.

[0048] For further information, see Figure 3 The connection between the first folding plate 121 and the second folding plate 122 is defined as the first bending portion 1211 , and the connection between the second folding plate 122 and the third folding plate 123 is defined as the second bending portion 1231 .

[0049] It can be understood that when the folding member 12 is in the storage state, the first folding plate 121 and the second folding plate 122 are neatly folded and stored in the folding groove 101, and the support plate 11 is in contact with the base plate 10. When the folding member 12 needs to be unfolded, the user applies force to the support plate 11 to drive the support plate 11 to move outward, and the support plate 11 drives the third folding plate 123 to move in the direction of the force application. After reaching a certain proximity state, the second bending portion 1231 is folded, and the folded third folding plate 123 drives the second folding plate 122 to gradually leave the folding groove 101. At this time, the third folding plate 123 and the base plate 10 form a direction toward each other. The angle of the support plate 11, the second folding plate 122 made of flexible material can be slid and pulled out toward the support plate 11 by the third folding plate 123, the first bending portion 1211 at the connection between the second folding plate 122 and the first folding plate 121 is folded, and the second folding plate 122 is pulled out of the folding groove 101 more and more until the support state required by the user is reached and the force is stopped, and the folded second folding plate 122 is stacked on the first folding plate 121. While performing the above actions, the connecting member 13 is also folded, and a triangular stable structure is formed between the connecting member 13, the support plate 11 and the base plate 10.

[0050] Specifically, the position of the first bending portion 1211 at the connection between the first folding plate 121 and the second folding plate 122 is not unique, and the first folding plate 121, the second folding plate 122 and the third folding plate 123 are integrally formed. When the folding member 12 is in the unfolded state, the amount of the second folding plate 122 folded away from the folding groove 101 is not unique, so the support angle is not unique, which is not limited in the present embodiment and can meet the folding needs of the user in the present embodiment.

[0051] Optionally, other combinations of folding plates may also be considered, such as adding more folding plates, each plate adopting a different folding method, such as flipping or rotating folding methods.

[0052] Furthermore, the connecting member 13 is movably connected to the support plate 11 and the substrate 10, and the connecting member 13 includes a first connecting member 131, a second connecting member 132, and a third connecting member 133 connecting the first connecting member 131 and the second connecting member 132. The first connecting member 131 is connected to the substrate 10, the second connecting member 132 is connected to the support plate 11, and the second connecting member 132 is arranged to fit the support plate 11.

[0053] It can be understood that the third connecting member 133 can be movable relative to the first connecting member 131 and the second connecting member 132 , thereby increasing the flexibility of the movable connection and supporting multi-angle adjustment of the connecting member 13 .

[0054] Specifically, to ensure the flexibility and stability of the connection, it is possible to consider increasing the strength of the first bend 1211 and the second bend 1231, adding a damping device or an angle connection device so that the user can adjust the tightness and activity of the connection part. The connector 13 can be made of a flexible or adjustable shape material, and can be deformed through various mechanisms such as folding, rotating or twisting when stored, and restore its original shape when unfolded to provide a stable connection.

[0055] Furthermore, a first fixing groove 102 is provided on the substrate 10 corresponding to the first connecting member 131 .

[0056] It can be understood that the first fixing groove 102 has a function of fixing and limiting the first connecting member 131 , thereby limiting the first connecting member 131 to a specific position on the substrate 10 .

[0057] Furthermore, the support plate 11 and the base plate 10 are circular in shape, and the connection point between the third connecting member 133 and the second connecting member 132 is located on the diameter of the support plate 11 .

[0058] Furthermore, the connection between the first connecting member 131 and the third connecting member 133 is defined as the third bending portion 1331 , and the connection between the second connecting member 132 and the third connecting member 133 is defined as the fourth bending portion 1332 .

[0059] Specifically, the second connector 132 in the connector 13 is arranged to fit the support plate 11. In order to completely store the second connector 132 and the third connector 133, the shapes need to be compatible with the support plate 11. Therefore, the second connector 132 and the third connector 133 can adopt a semicircular or fan-shaped design, which is more conducive to the corresponding setting of the support plate 11 and the second connector 132 and the third connector 133.

[0060] In this embodiment, the shape of the support plate 11 is not limited and can be set according to specific support requirements. In this embodiment, preferably, the shape of the support plate 11 can be circular or rounded rectangular, which can avoid the inconvenience caused by setting sharp corners.

[0061] It can be understood that the junction of the third connecting member 133 and the second connecting member 132 is located on the diameter of the support plate 11, so that the support plate 11, the third connecting member 133 and the second connecting member 132 can be parallel and have their centers facing each other, i.e., in a parallel state. This makes it easier for the user to directly take the entire magnetic bracket 1 from the connecting member 13 between the support plate 11 and the base plate 10.

[0062] It can be understood that the connecting member 13 plays the role of connecting the support plate 11 and the base plate 10 between the magnetic bracket 1. When the folding member 12 is in the storage state, the first connecting member 131 is fixed in the first fixing groove 102 on the base plate 10, and the second connecting member 132 is fixed on the support plate 11. The fourth bending portion 1332 at the connection between the third connecting member 133 and the second connecting member 132 is on the diameter of the support plate 11. Therefore, the third connecting member 133 can be parallel to the second connecting member 132 and fit with the support plate 11 to achieve a complete storage effect.

[0063] When the folding member 12 needs to be unfolded, the user applies force to the support plate 11, and the support plate 11 drives the third connecting member 133 arranged on the support plate 11 to unfold outward, and the third bending portion 1331 at the connection between the third connecting member 133 and the second connecting member 132 is located at the diameter of the support plate 11. When unfolding, the fourth bending portion 1332 at the connection between the third connecting member 133 and the second connecting member 132 and the third bending portion 1331 at the connection between the first connecting member 131 and the third connecting member 133 are folded at the same time, and the third connecting member 133 is folded from being parallel to the second connecting member 132 to forming a certain angle B (such as Figure 2 B), and forms a certain angle C (such as Figure 2 C).

[0064] For ease of understanding, an angle A (eg Figure 2 A), the third connecting member 133 and the second connecting member form an angle B (such as Figure 2 B), the third connecting member 133 and the first connecting member 131 form an angle C (such as Figure 2 In C), when the magnetic bracket 1 is in the unfolded state, the three corners form a firm triangular connection to provide stability for the support.

[0065] When the magnetic bracket 1 needs to be stored, the user applies force to the lower part of the support plate 11 that is not in contact with the third connecting member 133, and the support plate 11 drives the third folding plate 123 to apply an upward sliding force to the second folding plate 122, and part of the second folding plate 122 starts to flip from the first bending portion 1211 and is embedded in the folding groove 101. In this process, the angle C (such as Figure 2 C) and angle A (such as Figure 2 A) in the figure gradually decreases, and the angle B (such as Figure 2 B) gradually increases, when the angle C (such as Figure 2 C) and angle A (such as Figure 2 A) in the figure is reduced to 0°, and the angle B (such as Figure 2 B) in the figure is increased to 180°, and the magnetic bracket 1 is now stored.

[0066] Furthermore, the thickness of the third connecting member 133 is equal to the thickness of the second connecting member 132 , and the thickness of the first connecting member 131 is equal to the depth of the first fixing groove 102 .

[0067] It can be understood that equal thickness ensures that the connecting parts 13 have similar structural characteristics in different parts of the magnetic bracket 1, providing balanced stability, making the bracket more stable when unfolded and used. Equal thickness and depth can make the connecting parts 13 easier to cooperate with each other when folded, and the stress distribution is relatively uniform. The thickness of the first connecting part 131 is equal to the depth of the first fixing groove 102, so that the first connecting part 131 has a better fit in the first fixing groove 102, and the first connecting part 131 can be completely nested in the first fixing groove 102.

[0068] Furthermore, a second fixing groove 1321 is provided on the second connecting member 132 corresponding to the third folding plate 123 , and the third folding plate 123 is connected to the supporting plate 11 in the second fixing groove 1321 .

[0069] Furthermore, the thickness of the third folding plate 123 is equal to the depth of the second fixing groove 1321 .

[0070] It can be understood that the second fixed groove 1321 provides a space for the third folding plate 123 to be embedded in the groove, providing a smooth and beautiful appearance on the support plate 11, and cooperating with the setting of the first fixed groove 102 to further complete the fitting and storage effect of the support plate 11 and the substrate 10. The equal depth and thickness provide stability and alignment and prevent the third folding plate 123 from twisting or moving laterally in the second fixed groove 1321.

[0071] Specifically, the shape of the second fixing groove 1321 is adaptively arranged to the shape of the third folding plate 123, and the third connecting member 133 is connected to the support plate 11 in the second fixing groove 1321. While ensuring a stable connection, the second fixing groove 1321 can be designed as an annular groove, so that the third folding plate 123 can rotate around the support plate 11 after the second folding plate 122 is folded and pulled out, so that it is suitable for use on planes with different flatness or slopes.

[0072] Furthermore, the thickness of the first folding plate 121 and the second folding plate 122 is equal to the depth of the folding groove 101 .

[0073] Specifically, the size of the folding groove 101 needs to match the thickness of the first and second folding plates 122 to ensure that the folding member 12 can be safely nested in the groove in the storage state, and can complete the folding and withdrawal of the second folding plate 122 in the unfolded state and the restoration and fitting in the storage state.

[0074] Furthermore, a first magnetic member 103 is disposed on a side of the substrate 10 away from the support plate 11 , and a second magnetic member 104 is disposed in the second folding plate 122 .

[0075] It can be understood that the second magnetic component 104 in the second folding plate 122 helps the second folding plate 122 to be better stacked on the first folding plate 121 when in the unfolded state, and the first magnetic component 103 not only helps the magnetic bracket 1 to be better connected to electronic products such as mobile phones, but also provides stability support for the unfolding and storage process of the second folding plate 122.

[0076] See also Figure 4 and Figure 5 The second embodiment of the utility model provides a magnetic bracket 2. The difference between the magnetic bracket 2 in the second embodiment and the magnetic bracket 1 in the first embodiment is that a detachable decorative plate 14 is provided on a side of the support plate 11 away from the base plate 10.

[0077] Specifically, the area of ​​the decorative plate 14 is equal to or greater than the area of ​​the support plate 11, so as to completely cover the support plate 11, thereby playing a decorative role. Its specific shape can be a circle that fits the support plate 11 or other beautiful shapes.

[0078] Furthermore, a third magnetic component 141 is provided on the decorative plate 14 , and a fourth magnetic component 112 is provided on the support plate 11 corresponding to the third magnetic component 141 . The decorative plate 14 and the support plate 11 are magnetically connected via the third magnetic component 141 and the fourth magnetic component 112 .

[0079] Specifically, the third magnetic component 141 and the fourth magnetic component 112 can be any shape such as circular, annular or rectangular, and can be arranged at any position corresponding to the decorative panel 14 and the support panel 11. In this embodiment, the shape and position of the third magnetic component 141 and the fourth magnetic component 112 are not specifically limited, as long as the decorative panel 14 and the support panel 11 can be correctly adsorbed and connected.

[0080] For example, Figure 4 and Figure 5 In the magnetic connection between the decorative plate 14 and the support plate 11 shown, the decorative plate 14 and the support plate 11 are circular, the third magnetic component 141 and the fourth magnetic component 112 are circular, the third magnetic component 141 on the decorative plate 14 is set at the center position, and the corresponding fourth magnetic component 112 on the support plate 11 is set at the position corresponding to the fourth magnetic component 112 on the decorative plate 14.

[0081] Furthermore, a through hole or a notch is provided on the support plate 11 , and when the decorative plate 14 is magnetically connected to the support plate 11 , the decorative plate 14 covers the through hole or the notch.

[0082] Specifically, in this embodiment, it is shown as a through hole 111, the position of the through hole 111 does not conflict with the position of the fourth magnetic attraction member 112, and the through hole 111 is large enough so that the user's finger can easily pass through the through hole 111 and push the decorative plate 14 away from the support plate 11.

[0083] Optionally, in this embodiment, the position and shape of the through hole or the notch are not specifically limited. The through hole can be arranged in the middle part of the support plate 11 or at the edge, and can be circular, square or irregular in shape; the notch is arranged at the edge of the support plate 11, and can be a semicircular notch.

[0084] It can be understood that various patterns can be printed on the decorative plate 14 to enhance the aesthetics of the magnetic bracket and meet various personalized needs.

[0085] Optionally, the decorative plate 14 and the support plate 11 may be connected by a freely detachable connection method such as a latch, a snap connection or Velcro.

[0086] See also Figure 6 The third embodiment of the utility model provides a protective shell 3, which includes a shell body 30 and the magnetic bracket 1 and the magnetic bracket 2 as described above. The magnetic bracket 1 is arranged on the shell body 30, and a magnetic member 31 is arranged on a side of the substrate 10 away from the support plate 11. The shell body 30 is arranged on a side away from the support plate 11. The magnetic member 31 surrounds the magnetic bracket 1.

[0087] Specifically, when the magnetic bracket 1 is directly arranged on the shell body 30 of the protective shell 3, a circular hole is arranged on the shell body 30. The circular hole is used to place the magnetic bracket 1. The diameter of the circular hole at the position where the magnetic bracket 1 is arranged on the shell body 30, which is close to the support plate 11, needs to be smaller than the diameter of the substrate 10, so that the boundary of the substrate 10 can abut against the side of the circular hole away from the support plate 11, thereby preventing the magnetic bracket 1 from falling off from the shell body 30 and improving the stability of the connection between the magnetic bracket 1 and the shell body 30.

[0088] It can be understood that by directly setting the magnetic bracket 1 on the shell body 30 of the protective shell 3, when the protective shell 3 is in the state where the connecting member 13 and the folding member 12 are unfolded, that is, when the end of the connecting member 13 and the folding member 12 connected to the support plate 11 moves away from the substrate 10 and moves to the state where the connecting member 13 and the folding member 12 are unfolded, the support plate 11, the substrate 10 and the connecting member 13 form a triangular structure, thereby stabilizing the support plate 11 and improving the stability of the magnetic bracket 1 on the protective shell 3 in supporting electronic devices such as mobile phones and tablets. It should be noted that the shape of the magnetic member 31 can be set to be annular, so that the magnetic member 31 set on the shell body 30 can surround the substrate 10 on the magnetic bracket 1, thereby improving the magnetic attraction stability of the magnetic member 31.
