When the second magnetic steel 3 slides to a position close to the first magnetic steel 2, the first magnetic steel 2 and the second magnetic steel 3 interact with each other to increase the magnetic attraction force, so that the magnetic attraction component can stably adsorb the mobile electronic device; when the second magnetic steel 3 slides to a position away from the first magnetic steel 2, a partial area of ​​the magnetic attraction component is misaligned with the magnetic attraction area of ​​the mobile electronic device, so that the magnetic attraction force between the magnetic attraction component and the mobile electronic device is weakened, making it convenient for the user to pick up the mobile electronic device.

[0027] Furthermore, it also includes a slider 5, the mounting seat 1 is provided with a first sliding groove 11 that slides with the slider 5, the second magnetic steel 3 is fixedly connected to the slider 5, and the rotating seat 4 is transmission-connected to the slider 5.

[0028] It can be seen from the above description that the second magnetic steel 3 does not need to be made into a shape that matches the first sliding groove 11 , which can effectively reduce the difficulty of manufacturing the second magnetic steel 3 .

[0029] Furthermore, the cross section of the first sliding groove 11 is T-shaped, L-shaped or trapezoidal.

[0030] It can be seen from the above description that the shapes of the first sliding groove 11 and the sliding block 5 can be selected according to actual use requirements or production conditions.

[0031] Furthermore, the second magnetic steel 3 is connected to the slider 5 by adhesive bonding or screws.

[0032] It can be seen from the above description that the connection method between the second magnetic steel 3 and the slider 5 is simple and easy to assemble.

[0033] Furthermore, the rotating seat 4 is rotatable relative to the mounting seat 1 , and a second sliding groove 411 is provided on the rotating seat 4 to slide with the sliding block 5 .

[0040] Furthermore, the second magnetic steel 3 is disposed between two adjacent first magnetic steels 2 .

[0041] From the above description, it can be seen that when the multiple second magnetic steels 3 slide to a position close to the first magnetic steel 2, the magnetic attraction force of the magnetic attraction assembly is greatly enhanced, and when the multiple second magnetic steels 3 slide to a position away from the first magnetic steel 2, the magnetic attraction force of the magnetic attraction assembly is greatly weakened.

[0042] Furthermore, the first magnetic steel 2 and / or the second magnetic steel 3 are arc-shaped.

[0043] It can be seen from the above description that setting the first magnetic steel 2 and / or the second magnetic steel 3 in an arc shape and arranging them around the rotation axis of the rotating seat 4 can make the overall magnetic field of the magnetic attraction assembly more uniform.

[0044] Please refer to Figures 1 to 3 , Embodiment 1 of the present utility model is: a magnetic suction component with adjustable magnetic suction force, which can be applied to products such as mobile phone magnetic suction brackets.

[0045] The magnetic attraction component with adjustable magnetic attraction force includes a mounting seat 1, a first magnetic steel 2, a second magnetic steel 3 and a rotating seat 4; the first magnetic steel 2 is fixedly connected to the mounting seat 1; the second magnetic steel 3 is arranged on the mounting seat 1 and can slide relative to the mounting seat 1 to approach or move away from the first magnetic steel 2, and the magnetic orientation of the first magnetic steel 2 and the second magnetic steel 3 is the same; the rotating seat 4 is rotatably connected to the mounting seat 1 and is transmission-connected to the second magnetic steel 3, and the rotating seat 4 is used to drive the second magnetic steel 3 to slide relative to the mounting seat 1. Specifically, the magnetic attraction component also includes a slider 5, the mounting seat 1 is provided with a first slide groove 11 that slides with the slider 5, the second magnetic steel 3 is fixedly connected to the slider 5, and the rotating seat 4 is transmission-connected to the slider 5. Optionally, the second magnetic steel 3 is connected to the slider 5 by adhesive bonding or screws. In this embodiment, the cross-sections of the first slide groove 11 and the slider 5 are both T-shaped. In other embodiments, it is also feasible to set the cross-sections of the first slide groove 11 and the slider 5 to be L-shaped or trapezoidal.

[0046] The rotating seat 4 is rotatable relative to the mounting seat 1, and a second slide groove 411 is provided on the rotating seat 4 to slide with the slider 5. Specifically, the mounting seat 1 is in the shape of a circular plate, and the rotating seat 4 includes a circular bottom plate 41 and an annular top cover 42. The top cover 42 and the bottom plate 41 are arranged in a collinear manner in the axial direction, and the top cover 42 is fixedly connected to the top surface of the bottom plate 41. The top end of the top cover 42 is bent inward and extended to form an annular boss, and an annular groove is formed between the top cover 42 and the bottom plate 41. The mounting seat 1, the first magnetic steel 2, the second magnetic steel 3 and the slider 5 are all arranged on the inner side of the rotating seat 4, wherein the mounting seat 1 is arranged above the bottom plate 41 of the rotating seat 4, the mounting seat 1 and the rotating seat 4 are arranged in a collinear manner in the axial direction, the first magnetic steel 2 is fixedly connected to the top surface of the mounting seat 1, and the second magnetic steel 3 is arranged above the mounting seat 1. It is easy to understand that the top cover 42 of the rotating seat 4 can effectively reduce the wear caused by the contact between the first magnetic steel 2 and the second magnetic steel 3 and foreign objects. In other embodiments, it is also feasible that the mounting seat 1 and the rotating seat 4 are rotationally connected via a rotating shaft.

[0047] The length direction of the first slide groove 11 is perpendicular to the axial direction of the mounting seat 1. The first slide groove 11 connects the top surface, bottom surface and outer peripheral surface of the mounting seat 1, and the rotating seat 4 covers the opening of the first slide groove 11 located on the bottom surface and outer peripheral surface of the mounting seat 1. The second magnetic steel 3 is fixedly connected to the top surface of the slider 5. The bottom surface of the slider 5 is provided with a protruding convex rod 51, and the bottom plate 41 is provided with the second slide groove 411, and the second slide groove 411 is slidably matched with the convex rod 51. The second slide groove 411 is arc-shaped, and in a top-down perspective, the second slide groove 411 is cross-arranged with the first slide groove 11. The user only needs to make the rotating seat 4 and the mounting seat 1 rotate relative to each other, and use the side wall of the second slide groove 411 to squeeze the slider 5, so that the slider 5 can drive the second magnetic steel 3 to slide along the first slide groove 11. In other embodiments, the second slide groove 411 is a straight line or other linear slide groove, and in a top-down perspective, the second slide groove 411 is cross-arranged with the first slide groove 11.

[0048] At least a portion of the first magnetic steel 2 is exposed in the annular groove between the top cover 42 and the bottom plate 41. When the second magnetic steel 3 slides to a position close to the first magnetic steel 2 (such as Figure 1 As shown in FIG. 4 , at least a portion of the second magnetic steel 3 is exposed in the annular groove between the top cover 42 and the bottom plate 41. When the second magnetic steel 3 slides to a position away from the first magnetic steel 2 (as shown in FIG. 4 ), the second magnetic steel 3 is at least partially exposed in the annular groove between the top cover 42 and the bottom plate 41. Figure 2 As shown in FIG. 4 , the second magnetic steel 3 is completely contained in the annular groove between the top cover 42 and the bottom plate 41. It is easy to understand that exposing the first magnetic steel 2 and the second magnetic steel 3 to the annular groove can reduce the weakening effect of the magnetic attraction of the rotating seat 4 on the first magnetic steel 2 and the second magnetic steel 3.

[0049] There are multiple first magnetic steels 2. The multiple first magnetic steels 2 are evenly distributed around the rotation axis of the rotating seat 4. A second magnetic steel 3 is arranged between two adjacent first magnetic steels 2. Figure 3As shown, in this embodiment, the number of the first magnetic steel 2 and the second magnetic steel 3 are both three, and the number of the second magnetic steel 3, the slider 5 and the first slide slot 11 is set one by one. In other embodiments, it is also feasible to set the number of the first magnetic steel 2, the second magnetic steel 3, the slider 5 and the first slide slot 11 to two or more.

[0050] The first magnetic steel 2 and the second magnetic steel 3 are arc-shaped, and the axial directions of the first magnetic steel 2 and the second magnetic steel 3 are collinear with the axial direction of the mounting seat 1. When the plurality of second magnetic steels 3 slide to a position close to the first magnetic steel 2, the plurality of first magnetic steels 2 and the plurality of second magnetic steels 3 enclose to form a circular ring (such as Figure 1 As shown), the overall magnetic field of the magnetic attraction component can be made more uniform.

[0051] To summarize, the magnetic attraction component with adjustable magnetic attraction force provided by the utility model slidably mounts the second magnet on the mounting base. When the second magnet slides to a position close to the first magnet, the first magnet and the second magnet interact with each other to increase the magnetic attraction force, so that the magnetic attraction component can stably adsorb the mobile electronic device; when the second magnet slides to a position away from the first magnet, a partial area of ​​the magnetic attraction component is misaligned with the magnetic attraction area of ​​the mobile electronic device, so that the magnetic attraction force between the magnetic attraction component and the mobile electronic device is weakened, making it easier for the user to pick up the mobile electronic device.
