Detailed Implementation

[0036] The technical solutions of some 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, 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.

[0037] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0038] like Figures 1 to 8 As shown in the figure, this embodiment is a magnetic support, including a suction cup assembly 10, a folding arm 20 and a magnetic base 30. One end of the folding arm 20 is hinged to the base 11, and the other end is hinged to the magnetic base 30. The suction cup assembly 10 is used to attach to a flat surface. The folding arm 20 can be folded and unfolded. When folded, the magnetic support is small and easy to store. When unfolded, it supports objects by magnetic attraction through the magnetic base 30. The magnetic base 30 is provided with a bearing surface 301 for bearing objects. The magnetic base 30 is provided with a magnet assembly 34 inside, which is used to magnetically attract and confine objects to the bearing surface 301.

[0039] In this embodiment, the suction cup assembly 10 includes a base 11, a sliding block 13, a suction cup 14, and an elastic component 15. The lower end of the base 11 is provided with a chamber 101 with an opening. The suction cup 14 is located at the opening of the chamber 101. The middle part of the suction cup 14 is provided with a pull rod 141, and the side of the pull rod 141 away from the suction cup 14 is provided with a crossbar 142. The sliding block 13 is located on the base 11 and moves. The sliding block 13 is provided with a first stop 131, a second stop 132, and an inclined surface 133, wherein the inclined surface 133 is located between the first stop 131 and the second stop 132. The elastic component 15 is located between the base 11 and the suction cup 14. The elastic component 15 is a spring sleeved on the pull rod 141 and is used to restore the deformation of the suction cup 14.

[0040] The sliding block 13 moves in a direction perpendicular to the length of the pull rod 141. When the sliding block 13 is in the first state, the crossbar 142 engages in the first stop 131. When the sliding block 13 moves to the second state, the crossbar 142 leaves the first stop 131 and slides through the inclined plane 133 to the second stop 132. The pull rod 141 causes the suction cup 14 to deform toward the chamber 101.

[0041] Thus, through the structural design of the first stop 131, the second stop 132 and the inclined surface 133 of the sliding block 13, in conjunction with the crossbar 142 on the suction cup 14, the movement of the sliding block 13 drives the crossbar 142 from the first stop 131 along the inclined surface 133 to the second stop 132, causing the suction cup 14 to deform and generate an adsorption force. Conversely, the adsorption is released. The user only needs to push the sliding block 13 to move to perform adsorption and release, which is convenient to operate.

[0042] In this embodiment, the suction cup 14 is made of soft plastic material and is in the shape of a disc. The front side of the suction cup 14 is in contact with the plane, and the pull rod part 141 is located in the middle of the back side. When the pull rod part 141 drives the middle part of the suction cup 14 to deform towards the cavity 101, a vacuum is formed between the front side and the plane. The periphery of the suction cup 14 is tightly sealed to the plane, so that the suction cup 14 can be adsorbed on the plane.

[0043] In this embodiment, a bottom cover 12 is provided on the lower end of the base 11, and a chamber 101 is located on the bottom cover 12. A through hole 121 is provided on the bottom cover 12. A sliding block 13 is disposed in the inner cavity between the bottom cover 12 and the base plate. A pull rod 141 passes through the through hole 121 and cooperates with the sliding block 13. To guide the pull rod 141 to slide within the through hole 121 and prevent the suction cup 14 from rotating, a first limiting part 143 is provided on the side of the pull rod 141, and a second limiting part 122 is provided on the inner wall of the through hole 121. The first limiting part 143 cooperates with the second limiting part 122 to restrict the rotation of the pull rod 141. Exemplarily, the first limiting part 143 and the second limiting part 122 can be limiting sections, and the number can be set to one or more sets.

[0044] In this embodiment, the sliding block 13 is restricted to move within the cavity formed by the base 11 and the bottom cover 12. The sliding block 13 is provided with a clearance groove 134 for the pull rod 141 to pass through. The first limiting part 143 can also cooperate with the clearance groove 134 to limit the rotation of the pull rod 141. In the moving direction of the sliding block 13, the clearance groove 134 is symmetrically provided with a first stop 131, a second stop 132 and an inclined surface 133 on both sides to maintain balance. In the length direction of the pull rod 141, the distance between the first stop 131 and the suction cup 14 is less than the distance between the second stop 132 and the suction cup 14. When the crossbar 142 moves from the first stop 131 to the second stop 132, the pull rod 141 is displaced towards the base 11, causing the suction cup 14 to generate suction. Conversely, when the crossbar 142 moves from the second stop 132 to the first stop 131, the suction cup 14 returns to its original position and the suction disappears under the force of the elastic member 15.

[0045] In this embodiment, in order to push the sliding block 13 to move, buttons 16 are provided at both ends of the sliding block 13 in the direction of movement of the sliding block 13. The buttons 16 are exposed outside the base 11 and are configured to be pressed to push the sliding block 13 to move.

[0046] In this embodiment, the folding arm 20 has a two-section structure, including a first arm 21 and a second arm 22 that are hinged together. In order to make the magnetic bracket more compact when folded, the magnetic base 30 is provided with a receiving cavity 302, which is used to receive the folding arm 20.

[0047] In this embodiment, to allow the magnetic base 30 to rotate on the base 11, a rotatable turntable 17 is provided on the base 11. The folding arm 20 is hinged to the turntable 17, and a rotation positioning structure for rotation positioning is provided between the turntable 17 and the base 11. Specifically, a rotating shaft 111 is formed at the upper end of the base 11, and a shaft hole 171 is provided at the center of the turntable 17. The shaft hole 171 of the turntable 17 is fitted onto the rotating shaft 111, and a fixing plate 113 is connected to the end of the rotating shaft 111 to restrict the turntable 17.

[0048] An annular groove 112 coaxial with the rotating shaft 111 is formed on the base 11, and a convex ring 172 coaxial with the shaft hole 171 is formed on the turntable 17. The convex ring 172 cooperates with the annular groove 112 to increase the rotational stability of the turntable 17. The rotational positioning structure includes multiple positioning recesses 173 on the turntable 17 and a positioning component 18 on the base 11. The positioning recesses 173 are located on the convex ring 172, and the positioning component 18 cooperates with the positioning recesses 173 to realize the rotational positioning of the turntable 17. The positioning component 18 can be a ball screw or a similar functional component.

[0049] In this embodiment, the magnetic base 30 includes a main shell 31, a connecting plate 32, and a decorative cover plate 33. The connecting plate 32 and the decorative cover plate 33 are both connected to the main shell 31 and form an inner cavity for accommodating the magnet assembly 34 and an accommodating cavity 302 for accommodating the folding arm 20. The magnet assembly 34 is an annular structure composed of multiple magnets fixed on a fixing ring. The second arm 22 of the folding arm 20 is hinged to the connecting plate 32, wherein the bearing plane 301 is located on the decorative cover plate 33.
