[0001] The utility model relates to the technical field of magnetic attraction, and in particular to a magnetic attraction component and a magnetic attraction bracket. Background Art

[0002] With the development of wireless charging technology, mobile phones, tablets and other electronic products are equipped with magnets on the back so that the electronic products can be connected to the wireless charger magnetically. At the same time, the magnets on the back of the electronic products can be combined with magnetic components to fix the electronic products on external products such as brackets and refrigerators to facilitate fixing the electronic products at a specific angle. However, the existing magnetic components usually have the same magnetic attraction on both sides, which is difficult to adapt to different usage requirements and inconvenient to use. Utility Model Content

[0003] Therefore, in order to overcome at least some of the defects and shortcomings in the prior art, the embodiments of the present invention provide a magnetic suction component and a magnetic suction bracket, which can meet different usage requirements while ensuring the stability of the magnetic suction.

[0004] Specifically, one embodiment of the utility model provides a magnetic attraction component, including: a connecting member having a first surface and a second surface relative to each other; a first magnetic attraction structure, magnetically connected to the first surface; the first magnetic attraction structure includes a plurality of first magnetic attraction members arranged in sequence; a second magnetic attraction structure, magnetically connected to the second surface; the second magnetic attraction structure includes a plurality of second magnetic attraction members arranged in sequence.

[0005] In some embodiments, the first magnetic attraction structure has a first thickness perpendicular to the first surface direction, the second magnetic attraction structure has a second thickness perpendicular to the second surface direction, and the first thickness is greater than the second thickness.

[0006] In some embodiments, the first thickness is 1.7-2.3 mm.

[0007] In some embodiments, the second thickness is 0.6-1.2 mm.

[0008] In some embodiments, the first magnetic structure has a first magnetic region and a second magnetic region on the side facing the first surface, and the magnetic poles of the first magnetic region and the second magnetic region are opposite; the second magnetic structure has a third magnetic region and a fourth magnetic region on the side facing the second surface, and the magnetic poles of the third magnetic region and the fourth magnetic region are opposite; the first magnetic region and the third magnetic region are arranged opposite to each other and have opposite magnetic poles; the second magnetic region and the fourth magnetic region are arranged opposite to each other and have opposite magnetic poles.

[0009] In some embodiments, the connecting member is an annular structure, the first surface and the second surface are arranged opposite to each other in the axial direction of the connecting member; the multiple first magnetic members are arranged in a ring shape, and the multiple second magnetic members are arranged in a ring shape.

[0010] In some embodiments, the plurality of first magnetic elements and the plurality of second magnetic elements are arranged in one-to-one correspondence.

[0011] In some embodiments, the plurality of first magnetic elements are spaced apart from each other; and / or the plurality of second magnetic elements are spaced apart from each other.

[0012] An embodiment of the utility model also provides a magnetic attraction component, including: a connecting piece, which is an annular structure and has a first surface and a second surface opposite to each other along its axial direction; a first magnetic attraction structure, which is an annular structure, which is magnetically connected to the first surface and the axial direction of the first magnetic attraction structure is parallel to the axial direction of the connecting piece; a second magnetic attraction structure, which is an annular structure, which is connected to the second surface and the axial direction of the second magnetic attraction structure is parallel to the axial direction of the connecting piece.

[0013] The embodiment of the utility model further provides a magnetic bracket, comprising: a base; a magnetic attraction component as described in any one of the above items, fixedly connected to the base; and a support member, rotatably connected to the base.

[0014] As can be seen from the above, the above embodiments of the utility model can achieve one or more of the following beneficial effects: by setting the connecting member between the first magnetic attraction structure and the second magnetic attraction structure, the connecting member can interfere with the distribution of magnetic flux lines of the first magnetic attraction structure and the second magnetic attraction structure, so that the magnetic force on the side of the first magnetic attraction structure facing away from the first surface is stronger than the magnetic force on the side of the first magnetic attraction structure facing the first surface. Similarly, the magnetic force on the side of the second magnetic attraction structure facing away from the second surface is stronger than the magnetic force on the side of the second magnetic attraction structure facing the second surface. Therefore, the first magnetic attraction structure and the second magnetic attraction structure can be designed differently, and different magnetic attraction forces on both sides of the magnetic attraction component can be achieved. At this time, the first magnetic attraction structure and the second magnetic attraction structure can both guarantee a strong magnetic attraction force on the side facing away from the connecting member, so that different usage requirements can be met while ensuring the stability of the magnetic attraction.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0029] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0030] like Figure 1 As shown, the embodiment of the utility model provides a magnetic attraction assembly 10, including: a connecting member 11, a first magnetic attraction structure 12 and a second magnetic attraction structure 13. Figure 2 and Figure 3 The connecting member 11 has a first surface 111 and a second surface 112 opposite to each other. The first magnetic attraction structure 12 is magnetically connected to the first surface 111. The second magnetic attraction structure 13 is magnetically connected to the second surface 112.

[0031] Specifically, the connecting member 11 is, for example, an annular structure, for example, an annular sheet, and the material is, for example, a magnetic metal such as iron, silicon steel sheet, etc. The first surface 111 and the second surface 112 are two annular surfaces of the connecting member 11 that are opposite to each other in the axial direction of the shaft. The first magnetic attraction structure 12 and the second magnetic attraction structure 13 are, for example, magnets. The shapes of the first magnetic attraction structure 12 and the second magnetic attraction structure 13 are substantially the same as those of the connecting member 11. For example, when the connecting member 11 is an annular structure, the first magnetic attraction structure 12 and the second magnetic attraction structure 13 are also annular structures. The axial directions of the first magnetic attraction structure 12 and the second magnetic attraction structure 13 are parallel to the axial direction of the connecting member 11. For example, the first magnetic attraction structure 12 and the second magnetic attraction structure 13 are coaxially arranged. Among them, the first magnetic attraction structure 12 may include a plurality of first magnetic attraction members 121 arranged in sequence. When the first magnetic attraction structure 12 is an annular structure, it may be an integral annular magnet or a plurality of first magnetic attraction members 121 arranged in an annular structure. The second magnetic attraction structure 13 may include a plurality of second magnetic attraction members 131 arranged in sequence. When the second magnetic attraction structure 13 is an annular structure, it can be an integral annular magnet or a plurality of second magnetic attraction members 131 arranged in an annular structure. In some embodiments, for example, a plurality of first magnetic attraction members 121 are arranged at intervals from each other for ease of assembly. Similarly, a plurality of second magnetic attraction members 131 can also be arranged at intervals from each other.

[0032] In this embodiment, the annular structure of the connecting member 11, the first magnetic attraction structure 12 and the second magnetic attraction structure 13, the magnetic attraction component 10 is annular as a whole, which can be adapted to the annular magnet setting on the back of the existing electronic products. The "annular structure" can be a complete annular ring or an incomplete annular ring, for example, a "C"-shaped ring or a semicircular ring or annular segment. Of course, in some embodiments, the overall shape of the magnetic attraction component 10 may not be annular, that is, the connecting member 11 may not be annular, and multiple first magnetic attraction members 121 and multiple second magnetic attraction members 131 may be arranged according to the shape of the connecting member 11, which is not limited in this embodiment. In some embodiments, multiple first magnetic attraction members 121 and multiple second magnetic attraction members 131 are arranged one by one. That is, the number of the first magnetic attraction members 121 and the second magnetic attraction members 131 is the same and aligned. In other embodiments, the number of the first magnetic attraction members 121 and the second magnetic attraction members 131 may also be different, and the first magnetic attraction members 121 and the second magnetic attraction members 131 may also be arranged non-aligned, which is not limited in this embodiment.

[0033] In the magnetic attraction component 10 provided in this embodiment, the connecting member 11 is arranged between the first magnetic attraction structure 12 and the second magnetic attraction structure 13, so that the connecting member 11 can interfere with the distribution of magnetic flux lines of the first magnetic attraction structure 12 and the second magnetic attraction structure 13, so that the magnetic force of the side of the first magnetic attraction structure 12 facing away from the first surface 111 is stronger than the magnetic force of the side of the first magnetic attraction structure 12 facing the first surface 111. Similarly, the magnetic force of the side of the second magnetic attraction structure 13 facing away from the second surface 112 is stronger than the magnetic force of the side of the second magnetic attraction structure 13 facing the second surface 112. That is, in the magnetic attraction component 10, the side of the first magnetic attraction structure 12 and the second magnetic attraction structure 13 facing the connecting member 11 can be magnetically connected to each other through a weaker magnetic attraction force, while the side of the first magnetic attraction structure 12 and the second magnetic attraction structure 13 facing away from the connecting member 11 can be magnetically connected to an external structure such as an electronic product or a bracket through a stronger magnetic attraction force. For example, the first magnetic attraction structure 12 can be connected to the electronic product while the second magnetic attraction structure 13 can be connected to external devices such as a wireless charger and a refrigerator. Therefore, the first magnetic attraction structure 12 and the second magnetic attraction structure 13 can be designed differently. For example, the magnetic attraction force of the first magnetic attraction structure 12 is stronger than that of the second magnetic attraction structure 13, so that the magnetic attraction forces on both sides of the magnetic attraction component 10 are different. At this time, the first magnetic attraction structure 12 and the second magnetic attraction structure 13 can both guarantee a strong magnetic attraction force on the side facing away from the connecting member 11. Therefore, different usage requirements can be met while ensuring the stability of the magnetic attraction.

[0034] In some embodiments, the first magnetic structure 12 has a first thickness perpendicular to the first surface 111 (see Figure 4 H1 in the figure), the second magnetic attraction structure 13 has a second thickness perpendicular to the second surface 112 (refer to Figure 4 H2 in the figure), the first thickness H1 is greater than the second thickness H2. By making the thickness of the first magnetic structure 12 and the second magnetic structure 13 different, it can be achieved that the magnetic attraction force of the first magnetic structure 12 and the second magnetic structure 13 on the external device is different. For example, when an electronic product is magnetically attracted to an external device such as a refrigerator through the magnetic component 10, if it is necessary to keep the magnetic component 10 always connected to the electronic product, when the electronic product is removed from the external device such as the refrigerator, the magnetic component 10 can be easily separated from the external device but remain connected to the electronic product. In this way, the magnetic component 10 can be connected between the electronic product and the external device in a manner such that the first magnetic structure 12 is magnetically attracted to the electronic product, and the second magnetic structure 13 is magnetically attracted to the external device.

[0035] In some embodiments, the thickness of the connecting member 11 is, for example, 0.3 mm. The first thickness H1 is 1.7 to 2.3 mm, specifically 2.0 mm. The second thickness is 0.6 to 1.2 mm, specifically 0.9 mm.

[0036] In some embodiments, the first magnetic structure 12 has a first magnetic region and a second magnetic region on the side facing the first surface 111, and the magnetic poles of the first magnetic region and the second magnetic region are opposite. The second magnetic structure 13 has a third magnetic region and a fourth magnetic region on the side facing the second surface 112, and the magnetic poles of the third magnetic region and the fourth magnetic region are opposite. The first magnetic region and the third magnetic region are oppositely arranged, and the magnetic poles of the second magnetic region and the fourth magnetic region are oppositely arranged. Figure 4 , taking the area corresponding to one of the first magnetic attraction member 121 and the second magnetic attraction member 131 as an example, refer to Figure 4 In the orientation, the lower side (the side facing the connecting member 11) of the first magnetic member 121 (also known as the first magnetic structure 12) has the first magnetic region and the second magnetic region on the left and right sides, the first magnetic region is the S pole (South pole), and the second magnetic region is the N pole (North pole). The upper side (the side facing the connecting member 11) of the second magnetic member 131 (also known as the second magnetic structure 13) has the third magnetic region and the fourth magnetic region on the left and right sides, the third magnetic region is the N pole, and the fourth magnetic region is the S pole. The third magnetic region is located directly below the first magnetic region, and the fourth magnetic region is located directly below the second magnetic region. The first magnetic member 121 (first magnetic structure 12) and the second magnetic member 131 (second magnetic structure 13) can be magnetically attracted to each other. In some embodiments, when the first magnetic structure 12 is an annular structure, the first magnetic region and the second magnetic region are located on the inner side and the outer side of the annular structure, respectively. When the second magnetic attraction structure 13 is an annular structure, the third magnetic attraction area and the fourth magnetic attraction area are respectively located on the inner side and the outer side of the annular structure. In some embodiments, the magnetic attraction of the first magnetic attraction structure 12 on the same side (for example, both are the inner side of the ring or both are the outer side of the ring) facing the first surface 111 and facing away from the first surface 111 are opposite. The magnetic attraction of the second magnetic attraction structure 13 on the same side (for example, both are the inner side of the ring or both are the outer side of the ring) facing the second surface 112 and facing away from the second surface 112 are opposite.

[0037] Reference Figures 5 to 8 The present invention also provides a magnetic bracket 100, including the magnetic component 10 of any of the above embodiments, and also including a base 20 and a support 30. The magnetic component 10 is fixedly connected to the base 20, and the support 30 is rotatably connected to the base 20. The base 20 can be magnetically connected to the back of the electronic product (with a magnet on the back) through the magnetic component 10, and the support 30 can rotate around the base 20 to move from Figure 5 The storage status shown is switched to Figure 6 In the support state shown, one end of the support member 30 can be supported on a support surface such as a desktop so that the screen of the electronic product is at a specific angle to the support surface to meet the viewing effects of users at different angles.

[0038] Specifically, refer to Figure 7 and Figure 8 The base 20, for example, includes a containing shell 21, which encloses a containing groove 211, and the shape of the containing groove 211 matches the overall shape of the magnetic component 10. For example, if the overall shape of the magnetic component 10 is annular, the containing groove 211 is an annular groove. The magnetic component 10 can be installed in the containing groove 211 to achieve a fixed connection with the base 20. The base 20, for example, also includes a covering member 22, and the covering member 22 covers the notch of the containing groove 211, so that the magnetic component 10 can be limited in the containing shell 21. The support member 30, for example, surrounds the base 20 in the storage state, so that the support member 30 does not occupy additional thickness space in the storage state, so that the magnetic bracket 100 is flatter in the storage state, and the barrier between the magnetic component 10 and external devices can be reduced. In some embodiments, the magnetic bracket 100 further includes a handle 40, which is fixedly connected to the base. The handle 40 can be made of a flexible material such as rubber and made into a ring shape, so that the user can pass his fingers through the hole of the handle 40 to take the magnetic bracket 100. When the magnetic bracket 100 is connected to the electronic product, the electronic product can also be taken through the handle 40. When the magnetic bracket 100 needs to be removed from the back of the electronic product, the magnetic bracket 100 can also be better separated through the handle 40.

[0039] The principle of the magnetic bracket 100 provided by an embodiment of the utility model is as follows: first, when installing the magnetic bracket 100, the first magnetic structure 12 and the second magnetic structure 13 are respectively magnetically connected to the connecting member 11 to form an integral magnetic component 10, and the magnetic component 10 is installed in the receiving groove 211, and covered with the cover 22. When using the magnetic bracket 100, for example, the magnetic force of the first magnetic structure 12 facing away from the connecting member 11 is stronger than the magnetic force of the second magnetic structure 13 facing away from the connecting member 11, and in the base 20, the first magnetic structure 12 is closer to the cover 22 than the second magnetic structure 13, then the magnetic component 10 is magnetically connected to the back of the electronic product in a way that the cover 22 faces the electronic product. At this time, the first magnetic structure 12 is magnetically connected to the electronic product through the side of the first magnetic structure 12 facing away from the connecting member 11. The magnetic bracket 100 can be carried on the electronic product, and its supporting function can be realized by rotating the support member 30 to a suitable angle. After the support member 30 is stored, the electronic product can be magnetically connected to an external device such as a wireless charger through the other side of the magnetic bracket 100. At this time, the external device is magnetically connected through the second magnetic structure 13. For example, when the electronic product needs to be removed from the wireless charger after charging, since the magnetic force between the second magnetic structure 13 and the wireless charger is greater than the magnetic force between the first magnetic structure 12 and the electronic product, it can be ensured that the magnetic bracket 100 will not be separated from the back of the electronic product when the wireless charger is fully separated, and it will still remain magnetically attached to the back of the electronic product.
