[0043] Without changing the maximum magnetic force of the magnetic support, in order to make the user's action of separating the magnetically attractable device from the magnetic support more labor-saving, in the related art, the way adopted is to drive the magnet in the magnetic support to move, and by changing the relative position or angle between the magnet and the attracted object, the size adjustment of the magnetic force is realized. However, the magnet in the magnetic support and the driving component for driving the magnet need to be manually controlled by the user to reset after moving, which is relatively cumbersome to operate.

[0044] In view of this, see Figures 1-6The magnetic connection device 100 can be used for magnetically fixing any type of magnetically attractable equipment, the magnetically attractable equipment can have magnetism or can be magnetically fixed by assembling a magnetic accessory, and the magnetically attractable equipment can be a mobile phone or a tablet computer. The magnetic connection device 100 can rely on the magnetic attraction force to fix the magnetically attractable equipment, or can jointly act with other forces (for example, a supporting force, a clamping force, etc.) to fix the magnetically attractable equipment. According to the actual application scene, the magnetic connection device 100 can be fixed in different forms, for example, in a desktop environment, the magnetic connection device 100 can be directly placed on the desktop; in a vehicle environment, the magnetic connection device 100 can be fixed on the vehicle through a clamping mechanism or a magnetic attraction mechanism; in addition, the magnetic connection device 100 can be directly or indirectly held by a user, at this time, the magnetic connection device 100 can be a magnetic connection device 100 accessory connected to the back of the mobile phone, or be used for fixedly connecting the selfie stick and the mobile phone. In addition, the relative position reference relationship between the magnetic connection device 100 (including any part) and the magnetically attractable equipment described in the utility model is corresponding to the position relationship in a specific posture after the magnetic connection device 100 magnetically fixes the magnetically attractable equipment, unless otherwise specified.

[0045] Specifically, referring to Figures 1-6 The magnetic connection device 100 comprises a shell assembly 110, a magnetic assembly 120, a driving assembly 130 and a first elastic member 140. The shell assembly 110 has a cavity 111 and a magnetic surface 112 suitable for carrying the magnetically attractable equipment, and the cavity 111 is the inner cavity of the shell assembly 110. The magnetic assembly 120 is located in the cavity 111, and the magnetic assembly 120 is suitable for magnetically attracting the magnetically attractable equipment carried on the magnetic surface 112, so that the magnetic assembly 120 is used for providing the magnetic attraction force for attracting the magnetically attractable equipment.

[0046] It can be understood that the magnetic assembly 120 can be an embedded magnet block or a surface-exposed magnet block, and the magnetic surface 112 of the shell assembly 110 itself is configured to have magnetism, and the magnetic surface 112 serves as the magnetic assembly 120. It can be understood that in some embodiments, the magnetic assembly 120 plays an auxiliary role in fixing the magnetically attractable equipment to the magnetic connection device 100, that is, there is another structure for fixing the magnetically attractable equipment on the magnetic connection device 100, and the attracting effect of the magnetic assembly 120 is used together with the other fixing structure to stably fix the magnetically attractable equipment to the magnetic connection device 100.

[0047] Referring to Figures 1-6The driving assembly 130 is configured to drive the magnetic assembly 120 to move relative to the housing assembly 110, so that the magnetic assembly 120 can switch positions between the first position and the second position. The driving assembly 130 can drive the magnetic assembly 120 in any suitable manner, and the driving manner can be manual driving controlled by a user or automatic driving formed by a driving component such as a motor.

[0048] Referring to Figure 2 The first elastic member 140 is connected to the magnetic assembly 120. It should be noted that the first elastic member 140 can directly contact and connect the magnetic assembly 120. Alternatively, the first elastic member 140 can indirectly connect the magnetic assembly 120. In this case, the first elastic member 140 can be connected to the driving assembly 130, and the driving assembly 130 is connected to the magnetic assembly 120, so that the first elastic member 140 indirectly connects the magnetic assembly 120. In particular, when the magnetic assembly 120 is in the second position, the first elastic member 140 is configured to be locked in an elastically deformed state to store a first elastic force. After the first elastic force is released, the first elastic member 140 can drive the magnetic assembly 120 to move from the second position to the first position. One of the first position and the second position corresponds to a position where the magnetic assembly 120 can generate a larger magnetic attraction force (for example, the magnetic assembly 120 is closer to the magnetic attraction surface 112 in the first direction X at this time), and the other corresponds to a position where the magnetic assembly 120 can generate a smaller magnetic attraction force (for example, the magnetic assembly 120 is farther away from the magnetic attraction surface 112 in the first direction X at this time). For ease of description, the first position is taken as an embodiment in which the magnetic assembly 120 can generate a larger magnetic attraction force, and the second position is taken as an embodiment in which the magnetic assembly 120 can generate a smaller magnetic attraction force.

[0049] It can be seen that, in the scheme of the present application, the magnetic assembly 120 can be driven by the driving assembly 130 to adjust the magnetic attraction force, and the magnetic assembly 120 can be automatically restored to the first position from the second position by the first elastic force of the first elastic member 140. Compared with the related art, the magnet in the magnetic attraction support and the driving component for driving the magnet need to be manually controlled and reset after moving. In the scheme of the present application, the magnetic assembly 120 in the first position can be automatically moved to the second position by the elastic force of the first elastic member 140, thereby eliminating the corresponding operation and making the magnetic attraction force switching operation more convenient. Therefore, the magnetic connection device 100 of the present application can conveniently realize the magnetic attraction force switching operation.

[0050] For specific settings of the driving assembly 130, see Figures 1-6In some embodiments, the driving assembly 130 comprises a driving member 131, one end of which is rotatably connected to the housing assembly 110 and the other end of which is connected to the magnetic assembly 120, the rotation axis L of the driving member 131 is parallel to the first direction X, one end of the first elastic member 140 is connected to the housing assembly 110 and the other end of which is connected to the driving member 131, and the driving member 131 is configured to rotate along the circumferential direction around the rotation axis L to drive the magnetic assembly 120 to move from the first position to the second position and to exert the first elastic force on the first elastic member 140. It can be understood that the driving member 131 rotates in place and the overall position does not change during the position switching of the magnetic assembly 120 between the first position and the second position, and the driving member 131 can drive the magnetic assembly 120 to move, and the movement direction of the magnetic assembly 120 is not limited to the circumferential direction. In addition, the magnetic assembly 120 can exert the elastic force on the first elastic member 140 during the position switching, and the magnetic assembly 120 can also be locked in the first position when the first elastic member 140 is locked in the elastic deformation state.

[0051] For the specific arrangement of the driving assembly 130 to drive the magnetic assembly 120, see Figures 1-6 In some embodiments, the magnetic assembly 120 is slidably connected to the housing assembly 110 along the first direction X, the magnetic assembly 120 has a first inclined surface 121, the driving member 131 has a second inclined surface 1311, the first inclined surface 121 and the second inclined surface 1311 at least partially abut each other, and along the circumferential direction, the first inclined surface 121 and the second inclined surface 1311 both gradually extend towards the side close to the magnetic surface 112 along the first direction X, and the driving member 131 is adapted to rotate along the circumferential direction after being driven. Through the arrangement of the first inclined surface 121 and the second inclined surface 1311, when the driving member 131 rotates along the circumferential direction, the positions where the first inclined surface 121 and the second inclined surface 1311 contact each other relatively slide, and based on the above-mentioned sliding connection arrangement and the extension arrangement of the first inclined surface 121 and the second inclined surface 1311, the relative sliding of the first inclined surface 121 and the second inclined surface 1311 can drive the magnetic assembly 120 to move along the first direction X. Specifically, during the movement of the magnetic assembly 120 from the first position to the second position, the magnetic assembly 120 can slide along the first direction X and gradually move away from the magnetic surface 112. For example, in some embodiments, the inclination angles of the first inclined surface 121 and the second inclined surface 1311 are equal and are both 5 to 10 degrees, the relative sliding of the two can realize the lifting of the magnetic assembly 120 along the first direction X by about 1 to 2 mm, and the magnetic attraction force can be controlled to be 5 to 30 N.

[0052] For the specific structure of the driving assembly 130, see Figures 1-6In some embodiments, the driving assembly 130 further comprises an operating member 132 fixedly connected to the driving member 131 (the connection between the two can be detachable or non-detachable), the housing assembly 110 has a first operating through hole 113 communicating the cavity 111 with the outside, and the operating member 132 is arranged in the first operating through hole 113 and extends out of the housing assembly 110. More specifically, in some embodiments, the operating member 132 is configured to be able to rotate along the circumferential direction of the rotation axis L, and the operating member 132 comprises a first operating part 1321 and a connecting part 1322 connected to each other, the first operating part 1321 is arranged in the first operating through hole 113 and extends out of the housing assembly 110, and the connecting part 1322 is fixedly connected to the driving member 131. Through the above arrangements, the operating member 132 can be more convenient to operate the driving member 131.

[0053] In order to make the user operate the first operating part 1321 more labor-saving, referring to Figure 3 In some embodiments, the driving member 131 comprises a connecting end movably connected to the housing assembly 110, the extension direction of the operating member 132 is the radial direction of the rotation axis L, the first operating part 1321 and the connecting part 1322 are respectively located on the two sides of the connecting end, and the distance between the first operating part 1321 and the connecting end is greater than the distance between the connecting part 1322 and the rotation axis L. It can be understood that the position of the first operating part 1321 (i.e. the position of the connecting end) rotatingly connected to the housing assembly 110 can be used as a fulcrum, so that the first operating part 1321 forms a labor-saving lever mechanism, so that the user can rotate the first operating part 1321 by exerting a smaller force, and the connecting part 1322 on the other side further drives the connecting part 1322 to rotate with a larger force, thereby having the effect of labor-saving driving. When the movement of the driving member 131 is the rotation as described in the foregoing embodiments, the connecting end can correspond to the position of the rotation shaft of the driving member 131 rotatingly connected to the housing assembly 110, and the extension direction of the operating member 132 can be the radial direction of the rotation axis L.

[0054] In order to make the position of the magnetic assembly 120 more stable, referring to Figures 1-6In some embodiments, the magnetic connection device 100 further comprises a locking assembly 150, the locking assembly 150 having a third position and a fourth position, when the locking assembly 150 is in the third position, the locking assembly 150 abuts the side opposite to the direction of the driving assembly 130 in the circumferential direction to limit the movement of the locking member from the second position to the first position, at this time, the structure of the locking assembly 150 directly cooperating with the driving assembly 130 can form a ratchet structure; when the locking assembly 150 is in the fourth position, the locking assembly 150 is spaced from the driving assembly 130 to enable the first elastic force to be released. It can be understood that when the locking assembly 150 is in the third position, the rotation of the driving assembly 130 can be hindered, thereby hindering the first elastic member 140 from releasing the elastic force, so that the magnetic assembly 120 is locked in the second position, when the locking assembly 150 is in the fourth position, the above-mentioned hindering effect is no longer present, and thereafter the first elastic member 140 can drive the magnetic assembly 120 to move from the second position to the first position.

[0055] For specific movement cooperation settings of the locking assembly 150, see Figures 1-6 In some embodiments, the locking assembly 150 comprises a second operation part 151 and a locking part 152 connected to each other, the housing assembly 110 has a second operation through hole 114 communicating the cavity 111 with the outside, the second operation part 151 is arranged to pass through the second operation through hole 114 and extend out of the housing assembly 110, the locking part 152 abuts the driving assembly 130, and the second operation part 151 is configured to be able to drive the locking part 152 after obtaining the driving force, so that the locking assembly 150 moves from the third position to the fourth position. The second operation part 151 can drive the locking part 152 in any manner, for example, in some embodiments, the second operation part 151 and the locking part 152 can be directly connected, at this time, the second operation part 151 and the locking part 152 move synchronously and in the same direction; in other embodiments, the second operation part 151 drives the locking part 152 in a linkage transmission manner, for example, using linkage transmission, gear transmission, rack and pinion transmission, etc. The above-mentioned settings of the second operation part 151 can make the operation control of the user more convenient, and the structure and movement manner of the second operation part 151 can be the same as or similar to the first operation part 1321, in the embodiment shown in Figures 1-6 The first operation part 1321 is in the form of a lever, and the second operation part 151 is in the form of a button.

[0056] In order to enable the user to automatically reset after operating the locking assembly 150 to unlock (i.e., the locking assembly 150 moves from the third position to the fourth position), see Figure 3 and Figure 6In some embodiments, the locking assembly 150 further comprises a second elastic member 153 and a third elastic member 154, one end of the second elastic member 153 is connected to the housing assembly 110 and the other end is connected to the second operating part 151, one end of the third elastic member 154 is connected to the housing assembly 110 and the other end is connected to the locking part 152, the second operating part 151 is configured to obtain a driving force, the second elastic member 153 stores a second elastic force, and the third elastic member 154 stores a third elastic force, after the second operating part 151 loses the driving force, the second elastic force and the third elastic force are both released, so that the locking assembly 150 moves from the fourth position to the third position. After the above-mentioned elastic force is released, the locking assembly 150 returns to the state before being driven, so that the user's operation is more convenient. For the position switching mode of the locking assembly 150, in other embodiments, the position switching of the locking assembly 150 can be controlled by any other suitable structure, or can also be controlled by an electric driving mode.
