[0035] Example:

[0036] like Figures 1 to 9 As shown, in this embodiment, a magnetic bracket includes a base 10 and a cover 20 slidably connected to the base 10;

[0037] The base 10 has a magnetic member 40, and a magnetic adsorption area is formed on one side of the magnetic member 40 close to the cover 20. A magnetic adsorption surface 20a is formed on the cover 20 corresponding to the magnetic adsorption area. The magnetic adsorption area can provide a magnetic attraction force so that the electronic device is magnetically adsorbed on the magnetic adsorption surface 20a.

[0038] The cover body 20 has a magnetic shielding assembly 30; when the cover body 20 slides to a first position relative to the base 10, the magnetic shielding assembly 30 covers the magnetic adsorption area, and the magnetic attraction of the magnetic adsorption area is weakened; when the cover body 20 slides to a second position relative to the base 10, the magnetic shielding assembly 30 only covers part of or does not cover the magnetic adsorption area, and the magnetic attraction of the magnetic adsorption area is enhanced.

[0039] In this embodiment, the magnetic shielding component 30 is an iron sheet, and the working principle of the magnetic bracket is:

[0040] First, when the iron sheet covers the magnetic poles of the magnetic member 40, the iron sheet partially shields the magnetic field of the magnetic member 40, reducing the external magnetic effect of the magnetic poles. When the cover 20 slides to the first position relative to the base 10, the iron sheet covers the magnetic adsorption area (magnetic poles), so that the magnetic attraction of the magnetic adsorption area is weakened. When the cover 20 slides to the first position relative to the base 10, the structure of the magnetic adsorption bracket is as follows: Figure 3 and 4 shown.

[0041] When the iron sheet is placed near the magnetic pole of the magnetic part 40, but slightly deviates from the position directly opposite the magnetic pole, such as toward the edge of the magnetic pole, the iron sheet can help guide the magnetic field lines to a farther distance, thereby enhancing the range and magnetic attraction of the magnetic field provided by the magnetic part 40. When the iron sheet is away from the magnetic pole of the magnetic part 40, the magnetic attraction of the magnetic adsorption area (magnetic pole) is enhanced relative to when the iron sheet covers the magnetic pole of the magnetic part 40. When the cover 20 slides to the second position relative to the base 10, the magnetic attraction of the magnetic adsorption area (magnetic pole) is enhanced. When the cover 20 slides to the second position relative to the base 10, the structure of the magnetic bracket is as follows: Figure 1 and 2 shown.

[0042] Secondly, the electronic device adsorbed on the cover body 20 is relatively still with the magnetic surface 20a on the cover body 20. Due to the sliding switching of the cover body 20 relative to the base 10 between the first position and the second position, the distance between the electronic device and the magnetic part 40 on the base 10 also changes relatively. The distance between the electronic device and the magnetic part 40 when the electronic device is in the first position is farther than the distance between the electronic device and the magnetic part 40 when the electronic device is in the second position. The closer the electronic device is to the magnetic adsorption area (magnetic pole) of the magnetic part 40, the greater the magnetic attraction of the magnetic part 40 to the electronic device, and the electronic device can be stably adsorbed on the magnetic bracket. Conversely, the farther the electronic device is from the magnetic adsorption area (magnetic pole) of the magnetic part 40, the smaller the magnetic attraction of the magnetic part 40 to the electronic device, and the user can easily remove the electronic device from the magnetic bracket.

[0043] It should be noted that the iron sheet is only an example of the magnetic shielding component 30 in this embodiment. The magnetic shielding component 30 can also be other soft magnetic materials, magnetic shielding alloys, or a magnetic shielding paint containing powdered soft magnetic material coated on the cover 20.

[0044] Furthermore, the base 10 is in the shape of a groove, a magnetic part 40 is arranged in the groove of the base 10, and sliding rails 12 are symmetrically arranged on both sides of the magnetic part 40. The two side edges of the cover body 20 or the magnetic shielding assembly 30 extend toward the base 10 to form a clamping part 31, and the clamping part 31 is slidably connected to the sliding rail 12 along a direction parallel to the bottom of the groove of the base 10.

[0045] If the magnetic shielding component 30 is made of a soft magnetic material or a magnetic shielding alloy, the magnetic shielding component 30 can be fixed to the cover 20 by adhesive fixation, thread fixation, snap fixation or other connection methods.

[0046] In this embodiment, if Figures 5 to 8 As shown, the two sides of the magnetic shielding assembly 30 extend toward the base 10 to form a clamping portion 31, the cover 20 is glued and fixed to the side of the magnetic shielding assembly 30 away from the base 10, and the clamping portion 31 is slidably connected to the sliding track 12. In the thickness direction of the base 10 and the cover 20, the clamping member limits the freedom of the cover 20 relative to the base 10, so that the cover 20 can only slide relative to the base 10. The magnetic bracket set in this way has a simple structure and low manufacturing cost. The magnetic attraction of the magnetic bracket can be changed by sliding operation, so that the electronic equipment can be stably adsorbed on the magnetic bracket and can also be quickly removed.

[0047] In other embodiments, the two side edges of the cover body 20 may extend toward the base 10 to form the clamping portion 31 to achieve relative movement between the cover body 20 and the base 10 .

[0048] Furthermore, if Figure 8 As shown, an assembly groove 11 is provided in the groove of the base 10 , and the magnetic member 40 is assembled into the assembly groove 11 . In the length extension direction of the base 10 , the sliding track 12 extends from the assembly groove 11 to the groove wall at one end of the base 10 .

[0049] It should be understood that the magnetic member 40 can be a permanent magnetic material such as a magnet, etc., and the shape of the magnetic member 40 can be various, such as cylindrical, square or annular, etc., which are not limited here. The shape and structure of the assembly groove 11 match the magnetic member 40, and can be set accordingly according to the shape of the selected magnetic member 40.

[0050] Furthermore, if Figure 8 As shown, guide walls 121 extend toward one end of the base 10 on both sides of the assembly groove 11 , and a guide groove 122 is recessed on one side of the guide wall 121 facing the groove wall of the adjacent base 10 , forming a sliding track 12 between the guide wall 121 and the groove wall of the adjacent base 10 .

[0051] like Figure 5 and 6As shown, the clamping portion 31 includes a clamping arm 311 and a clamping protrusion 312. Both sides of the magnetic shielding assembly 30 extend toward the base 10 to form two clamping arms 311. One end of the two clamping arms 311 away from the magnetic shielding assembly 30 is bent toward each other to form a clamping protrusion 312.

[0052] like Fig. 9 As shown, each engaging protrusion 312 is engaged in the corresponding guide slot 122 , so that the magnetic shielding assembly 30 can slide along the guide slot 122 .

[0053] From the end of the guide wall 121 close to the assembly groove 11, the clamping arm 311 and the clamping protrusion 312 of the magnetic shielding assembly 30 can be quickly inserted into the sliding rail 12, and the clamping protrusion 312 and the guide groove 122 play a limiting role in the thickness direction of the cover body 20 and the base 10. With this arrangement, the magnetic bracket has a simple structure, simple disassembly and assembly, and low production cost.

[0054] Furthermore, if Figure 5 and 8 As shown, the assembly groove 11 is annular, the magnetic shielding assembly 30 is annular, and the magnetic member 40 matches the assembly groove 11 .

[0055] The magnetic member 40 matches the assembly groove 11 and is also in a continuous or discontinuous ring shape. The ring-shaped magnetic member 40 can generate a uniform magnetic field distribution, which is conducive to the uniform distribution of the magnetic force on the magnetic attraction surface 20a. Compared with the magnetic member 40 of other shapes such as a square, the stability and reliability of magnetic adsorption are improved.

[0056] In addition, the ring-shaped magnetic member 40 can also generate a larger magnetic field strength in a relatively small volume, so that the volume of the magnetic bracket is smaller, and a larger magnetic attraction force can be provided under the same volume, and the scope of application is wider.

[0057] It should be known that the magnetic part 40 can be a ring magnet with a certain thickness along a continuous circular trajectory, or the magnetic part 40 can be a multi-segment circular arc magnet with a certain thickness along a discontinuous circular trajectory, and the arc lengths of each segment of the circular arc magnet can be the same or different. Preferably, each segment of the circular arc magnet is arranged in an evenly array at equal angles in the assembly groove 11 to ensure that the magnetic attraction to the electronic device is evenly distributed.

[0058] Furthermore, if Figure 7 and 8 As shown, the assembly groove 11 is integrally formed with a plurality of partitions 111 , which divide the assembly groove 11 into multiple sections. The magnetic component 40 is assembled in the multiple sections of the assembly groove 11 , and the assembly groove 11 and the magnetic component 40 are symmetrical about the center of the circle of the assembly groove 11 .

[0059] In order to assemble the magnetic part 40 in the multi-segment groove body of the assembly groove 11, it can be understood that the magnetic part 40 can use a non-continuous multi-segment arc-shaped magnet with a certain thickness. Compared with using a continuous annular magnetic part 40, this arrangement reduces the cost and ensures that the magnetic part 40 can provide uniform and sufficient magnetic attraction.

[0060] During the production process, the partition 111 plays a positioning role. The partition 111 pre-divides the assembly groove 11 into multiple sections evenly spaced, so that the magnetic component 40 can be quickly assembled into the corresponding multi-section groove body, thereby improving the production efficiency of the magnetic bracket.

[0061] The magnetic member 40 may be interference fitted into the assembly slot 11 , or may be glued or snap-connected into the assembly slot 11 . The specific connection method for fixing the magnetic member 40 to the assembly slot 11 is not limited herein.

[0062] Furthermore, if Figure 8 As shown, in the direction parallel to the bottom of the groove of the base 10, the cross-sections of the two ends of the base 10 along the length direction are arc-shaped and the center of the first end overlaps with the center of the assembly groove 11;

[0063] like Figure 4 As shown, when the cover 20 slides to the first position relative to the base 10, the center of the magnetic shielding assembly 30 overlaps with the center of the assembly groove 11;

[0064] like Figure 2 As shown, when the cover 20 slides to the second position relative to the base 10 , the center of the magnetic shielding assembly 30 overlaps with the center of the first end of the base 10 along the length direction.

[0065] Since both ends of the base 10 are arc-shaped and the magnetic shielding assembly 30 is ring-shaped, the first end of the base 10 also overlaps with the center of the assembly groove 11. When the cover body 20 slides to the first position relative to the base 10, the center of the magnetic shielding assembly 30 overlaps with the center of the assembly groove 11. When the cover body 20 slides to the second position relative to the base 10, the center of the magnetic shielding assembly 30 overlaps with the center of the first end of the base 10 along the length direction. Such a design can achieve precise alignment of the cover body 20 and the base 10.

[0066] Preferably, the magnetic shielding assembly 30 is partially located in the groove of the base 10 in the thickness direction. On the one hand, it can improve the stability of the cover body 20 and the base 10 when they slide relative to each other, and prevent the cover body 20 from swaying or becoming unstable during the sliding process; on the other hand, this can achieve the limitation of the movement of the cover body 20, so that the cover body 20 can slide within a certain range relative to the base 10.

[0067] Furthermore, if Figure 5 and 6As shown, in the direction from the first position to the second position, the first section of the clamping arm 311 extends along the radial tangent direction of the magnetic shielding assembly 30 , and the second section of the clamping arm 311 extends along the circular track of the magnetic shielding assembly 30 .

[0068] like Figure 2 As shown, when the cover slides to the second position relative to the base 10, since the two ends of the base 10 are arc-shaped, the second end of the clamping arm 311 extends along the circular trajectory of the magnetic shielding assembly 30 to avoid interference between the clamping arm 311 and the inner wall of the base 10, so that the movable distance of the clamping arm 311 along the sliding track 12 is increased, and the space required for the movement of the magnetic shielding assembly 30 is reduced, thereby reducing the volume of the entire magnetic bracket, making the magnetic bracket more flexible and compact.

[0069] Furthermore, a gasket 50 is provided on a side of the cover 20 facing away from the base 10 . The gasket 50 at least covers the magnetic attraction surface 20 a . The gasket 50 is used to increase the friction between the electronic device and the cover 20 .

[0070] like Figure 1 and Fig. 9 As shown, the gasket 50 can be fixed on the cover plate by gluing or double-shot molding. Preferably, the gasket 50 is circular and covers the magnetic attraction surface 20a.

[0071] The gasket 50 can be a silicone pad or a rubber pad or other material with a certain degree of elasticity or flexibility. On the one hand, it can increase the friction between the electronic device and the cover 20, so that the electronic device can be more stably adsorbed on the magnetic bracket. On the other hand, the cover 20 and the base 10 are mostly hard materials. The use of the gasket 50 can reduce the wear between the electronic device and the cover 20 and increase the service life of the electronic device and the magnetic bracket.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
