Description
TECHNICAL FIELD
[0001] The application relates to a folding magnetic support structure for a smart phone, in particular to a folding magnetic support structure. BACKGROUND
[0002] Some smart phones are provided with a built-in magnet piece, which is arranged around a built-in wireless charging coil to form a built-in magnet ring to realize magnetic positioning during wireless charging. Some magnetic support structures for the smart phones on the market are fixed on the back of the smart phones through mutual magnetic attraction with the built-in magnet ring. The magnetic support structure body can be folded on the back of the smart phone, and the support structure is unfolded for use when needed. Due to the annular body for magnetically attracting the built-in magnet ring of the smart phone and the folding support structure, the magnetic support structure has relatively large volume and thickness, which hinders the magnetic wireless charging of the smart phone. The user has to remove the support structure on the back of the smart phone before the magnetic wireless charging can be performed, and the use convenience is poor, which needs to be improved. CONTENT OF THE UTILITY MODEL
[0003] The application aims to overcome the above problems of the prior art and provide a folding magnetic support structure to improve the use convenience.
[0004] To achieve the above object, the application adopts the following technical scheme: a folding magnetic support structure, which comprises a main body and a folding support structure. The main body is provided with a receiving groove and an arc-shaped boss with a circular-arc-shaped inner cavity. The lower part of the arc-shaped boss is provided with a gap. The receiving groove penetrates through the gap of the arc-shaped boss and partially penetrates into the arc-shaped boss. The folding support structure is arranged in the receiving groove. The inner cavity of the arc-shaped boss is provided with a first magnet piece group, a second magnet piece group and an annular intermediate iron piece. The intermediate iron piece is coaxial with the arc-shaped boss. The first magnet piece group and the second magnet piece group are respectively fixed to the front and back surfaces of the intermediate iron piece. The magnet pieces of the first magnet piece group and the magnet pieces of the second magnet piece group are distributed around the central axis of the arc-shaped boss. The polarities of the magnet pieces of the first magnet piece group and the magnet pieces of the second magnet piece group are opposite.
[0005] In an optional scheme, the folding support structure comprises a base plate, a movable small plate, a first large plate and a second large plate. The base plate is fixed on the bottom surface of the receiving groove. The two short sides of the base plate are respectively rotationally connected with the movable small plate and the first large plate. The two short sides of the second large plate are respectively rotationally connected with the first large plate and the movable small plate. When the folding support structure is completely folded, the movable small plate is attached to the bottom surface of the receiving groove, and the included angle between the first large plate and the second large plate is 180°.
[0006] In an optional scheme, when the folding support structure is completely folded, the movable small plate is located at the end of the receiving groove away from the arc-shaped boss.
[0007] In an optional scheme, a magnet is arranged in the movable small plate, and an iron plate is arranged in the base plate. When the movable small plate is rotated and attached to the base plate, the magnetic attraction force between the magnet and the iron plate fixes the movable small plate to the base plate.
[0008] In an alternative, the movable plate is located in the part of the accommodating groove that penetrates into the arc-shaped boss when the folding support is fully folded.
[0009] In an alternative, the folding support covers the entire accommodating groove when it is fully folded.
[0010] In an alternative, the inner cavity opening of the arc-shaped boss is provided with a ring-shaped sealing plate, which is located on the other side of the accommodating groove.
[0011] In an alternative, the side wall of the accommodating groove is provided with an arc-shaped groove for pushing the folding support, which is located on the outside of the arc-shaped boss.
[0012] The technical solution of the present application uses the gap of the accommodating groove that penetrates into the arc-shaped boss, and places the folding support in the accommodating groove. The arc-shaped boss is internally provided with the first magnet piece group and the second magnet piece group. Therefore, the folding support and the first magnet piece group and the second magnet piece group overlap in the thickness direction, and the thickness of the entire structure can be designed to be smaller. At the same time, the first magnet piece group can magnetically attract the built-in magnet ring, and the second magnet piece group can magnetically attract the magnet of the external wireless charger. That is, the support structure does not need to be removed for magnetic attraction wireless charging during wireless charging, which improves the convenience of use and meets the user's needs. Alternatively, the second magnet piece group can be used to attract the entire smart phone to other ferromagnetic objects, such as refrigerators / iron doors, etc., to further improve the application range of the product.
[0013] The above description is only a summary of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the content of the specification, and in order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following preferred embodiments are described in detail as follows.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] This application embodiment is a foldable magnetic support structure, the specific structure of which is as follows: Figures 1-5 As shown. Combined with Figure 1 and Figure 2 As shown, the folding magnetic bracket structure includes a main body 10 and a folding bracket 20. The main body 10 can be made of silicone, and the folding bracket 20 can be made of silicone or leather. The main body 10 has a receiving groove 11 and an arc-shaped inner cavity 121. Figure 3 The arc-shaped boss 12 has a notch 122 at its lower part. A receiving groove 11 passes through the notch 122 and partially enters the arc-shaped boss 12. Therefore, the folding bracket 20 is placed in the receiving groove 11, and in the thickness direction A, the folding bracket 20 overlaps with the arc-shaped boss 12. Figure 3 As shown, the inner cavity 121 of the arc-shaped boss 12 houses a first magnet group 31, a second magnet group 32, and an annular intermediate iron plate 33. The intermediate iron plate 33 is coaxial with the arc-shaped boss 12. The first magnet group 31 and the second magnet group 32 are fixedly attached to the front and rear surfaces of the intermediate iron plate 33, respectively. The intermediate iron plate 33 is used to fix the first magnet group 31 and the second magnet group 32, and at the same time, it can also enhance the magnetism and the overall rigidity of the product. The magnets 311 of the first magnet group 31 and the magnets 321 of the second magnet group 32 are distributed around the central axis Z of the arc-shaped boss 12, and the polarity of the magnets 311 of the first magnet group 31 is opposite to that of the magnets 321 of the second magnet group 32. Therefore, the first magnet group 31 can be used to magnetically attract the built-in magnet ring of a smartphone, while the second magnet group 32 can be used to magnetically attract the magnet of an external wireless charger, achieving magnetic fixation during wireless charging.
[0023] Therefore, the folding magnetic bracket structure of the embodiment has the receiving groove 11 passing through the notch 122 of the arc-shaped protrusion 12, and the folding bracket 20 is placed in the receiving groove 11. The arc-shaped protrusion 12 has a first magnetic piece group 31 and a second magnetic piece group 32 built in it. Therefore, the folding bracket 20 overlaps with the first magnetic piece group 31 and the second magnetic piece group 32 in the thickness direction. The thickness of the entire structure is not the sum of the thickness of the folding bracket 20 and the thickness of the arc-shaped protrusion 12, so the overall structural thickness is reduced. When the smartphone with the folding magnetic bracket structure of the embodiment on the back is wirelessly charged, if the external wireless charger has a magnetic wireless charging function, the first magnetic piece group 31 can magnetically attract the built-in magnetic ring of the smartphone, and the second magnetic piece group 32 can magnetically attract the magnet of the external wireless charger. That is, magnetic wireless charging can be performed directly without removing the folding magnetic bracket structure, which improves the convenience of use.
[0024] like Figure 1 As shown, when the folding bracket 20 is fully folded, it fills the entire receiving groove 11, effectively utilizing the space of the entire product. Furthermore, when the folding bracket 20 is fully folded, in the thickness direction A, the folding bracket 20 extends beyond the arc-shaped boss by a maximum of 0.5 mm.
[0025] In some embodiments, combined with Figure 1 and Figure 2 As shown, the two opposite side walls 112 of the receiving groove 11 are respectively provided with arc-shaped grooves 113 for opening the folding bracket 20. The arc-shaped grooves 113 are located on the outside of the arc-shaped boss 12. When it is necessary to open the folding bracket 20, the folding bracket 20 can be opened by pulling it outward with a finger at the arc-shaped groove 113.
[0026] In some embodiments, such as Figure 3 As shown, an annular sealing plate 40 is glued to the outer end face of the opening of the inner cavity 121 of the arc-shaped boss 12. The annular sealing plate 40 is disposed in the opposite receiving groove 11. Figure 2 On the other side of the cavity 121, the annular sealing plate 40 seals the cavity 121 to prevent the first magnet assembly 31, the second magnet assembly 32, and the intermediate iron piece 33 from detaching from the cavity 121, while also improving the overall appearance of the product. The annular sealing plate 40 may be made of hard plastic.
[0027] In some embodiments, such as Figure 4 and Figure 5As shown, the folding bracket 20 includes a base plate 21, a movable small plate 22, a first large plate 23, and a second large plate 24. The base plate 21 can be fixed to the bottom surface 114 of the receiving groove 11 with glue. The two short sides of the base plate 21 are rotatably connected to the movable small plate 22 and the first large plate 23, respectively, and the two short sides of the second large plate 24 are rotatably connected to the first large plate 23 and the movable small plate 22, respectively. Therefore, the first large plate 23, the second large plate 24, and the movable small plate 22 can be rotated relative to each other to a suitable position for convenient use. Figure 4 The diagram shows one usage state of the folding stand 20. When a user holds a smartphone, their fingers are inserted into the space enclosed by the folding stand 20, which assists in holding the smartphone. When the folding stand 20 is fully folded, the movable small plate 22 will fit against the bottom surface 114 of the receiving groove 11, and the included angle between the first large plate 23 and the second large plate 24 is 180°. Furthermore, when the folding stand 20 is fully folded, the movable small plate 22 will be located at the end of the receiving groove 11 away from the arc-shaped protrusion 12. Figure 5 As shown, a magnet 221 is built into the movable plate 22, while an iron plate 211 is built into the base plate 21. When the movable plate 22 rotates and overlaps with the base plate 21, the magnetic attraction between the magnet 221 and the iron plate 211 fixes the movable plate 22 to the base plate 21. Therefore... Figure 5 The folding bracket 20 shown forms a stable triangle. When the folding magnetic bracket structure is attached to the back of the smartphone, it can be used as a phone stand.
[0028] In other embodiments, such as Figure 6 The folding bracket 20 shown is fixed in reverse in the receiving groove 11, that is, the movable plate 22 is located at the upper part of the receiving groove 11. When the folding bracket 20 is fully folded, the movable plate 22 will be located in the part of the receiving groove 11 that passes through the arc-shaped boss 12. Figure 6 In the folding bracket 20 shown, the movable small plate 22 does not have an embedded magnet, and the base plate 21 does not have an embedded iron plate. Therefore, the folding bracket 20 will not affect wireless charging after it is folded.
