[0042] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of the utility model protection.

[0045] Without changing the maximum magnetic force of the magnetic support, in order to make the user's action of separating the magnetizable device from the magnetic support more labor-saving, in the related art, a movable shielding material is arranged to adjust the magnetic force. However, the design of the shielding material often needs to adapt to the shape of the magnet of the magnetic support, and occupies a large installation space, so there are many limitations in such design.

[0046] Specifically, the shielding material in the related art is stacked on the upper side of the magnet, if the magnet is annular, the shielding material also needs to be annular accordingly, and the magnetic force is adjusted by rotating the shielding material to different positions, at this time, the magnet and the shielding material need to be designed as a segmented annular structure with a spacing, or the magnet and the shielding material need to be designed as a special structure with a circumferential staggered polarity distribution, greatly increasing the complexity of the design.

[0047] In view of this, referring to Figures 1-8The embodiment of the utility model provides a kind of magnetic connecting device 100, the magnetic connecting device 100 can be used for magnetically attracting and fixing arbitrary type of magnetically attractable equipment, the magnetically attractable equipment itself can have magnetism, or by assembling magnetic accessory to make it can be magnetically attracted and fixed, and the magnetically attractable equipment specifically can be mobile phone or tablet computer.Magnetic connecting device 100 can only rely on the action of magnetic attraction force to fix magnetically attractable equipment, and can also act together with other forces (such as supporting force, clamping force etc.) to fix magnetically attractable equipment.According to actual application scene, magnetic connecting device 100 itself can adopt different forms to fix, for example, in desktop environment, magnetic connecting device 100 can be placed directly on desktop;In vehicle environment, magnetic connecting device 100 can be fixed on vehicle by its own clamping mechanism or magnetic attraction mechanism;In addition, magnetic connecting device 100 can also be directly or indirectly held by user, and the magnetic connecting device 100 at this time can be the support accessory connected to the back of mobile phone, or be used for the fixed connection of selfie stick and mobile phone.In addition, the relative orientation reference relationship between the magnetic connecting device 100 (including any part) described in the utility model and the magnetically attractable equipment, if no special description, is the positional relationship in the specific attitude after magnetically attractable equipment is magnetically attracted and fixed by magnetic connecting device 100.

[0048] Specifically, refer to Figures 1-5 Magnetic connecting device 100 includes shell assembly 110, magnetic assembly 120, medium assembly 130 and drive assembly 140.Shell assembly 110 has cavity 111 and magnetic attraction surface 112, and magnetic attraction surface 112 is suitable for carrying magnetically attractable equipment, and the direction perpendicular to magnetic attraction surface 112 is defined as first direction X, and magnetic attraction surface 112 is located on one side of cavity 111 along first direction X. Among them, cavity 111 is the inner cavity of shell assembly 110 itself, and magnetic attraction surface 112 is the outer wall surface of one side of shell assembly 110.

[0049] Refer to Figures 3-4The magnetic assembly 120 and the medium assembly 130 are located in the cavity 111, and the magnetic assembly 120 is used to provide a magnetic attraction force for attracting the magnetically attractable device. In combination with the foregoing description of the shell assembly 110, when the user needs to magnetically attract and fix the magnetically attractable device, the magnetically attractable device can be placed on the magnetic attraction surface 112, and at this time, the magnetically attractable device is attached to the magnetic attraction surface 112 under the magnetic attraction of the magnetic assembly 120, so that the magnetically attractable device can be fixed on the magnetic connection device 100. It should be noted that the attachment effect described in the utility model needs to exclude the influence of errors and microscopic gaps. The magnetic assembly 120 extends in a ring shape along the circumferential direction R of the first direction X. More specifically, the magnetic assembly 120 can be a magnetic ring, and the shape, size and polarity can correspond to the magnetic ring structure on the magnetically attractable device. It should be noted that in the description of the utility model, the extension along the circumferential direction R and the ring structure will not limit the shape of the extension track to be a circular ring, so the extension track under this limitation can also be a rectangular ring, an elliptical ring or any other shape of ring.

[0050] In particular, referring to Figures 1-5 The medium assembly 130 extends in a ring shape along the circumferential direction R and faces the magnetic assembly 120, and when the medium assembly 130 is located around the magnetic assembly 120, the size of the magnetic attraction force can be changed. According to the above description of the function, the material of the medium assembly 130 can be any one of a magnetic isolation material, a shielding material and a magnetic induction material. In order to adjust the influence of the medium assembly 130 on the magnetic attraction force in different states, the driving assembly 140 is configured to drive the medium assembly 130 to move along the first direction X. According to the requirements, the driving assembly 140 can drive the medium assembly 130 in any suitable manner, and the specific driving manner will be described later. It should be noted that as long as the medium assembly 130 can change the magnetic attraction force, any side wall surface (including any type of wall surface such as a flat surface and a spherical surface) of the medium assembly 130 can face the magnetic assembly 120.

[0051] It can be seen that the magnetic connection device 100 of the utility model includes a shell assembly 110, a magnetic assembly 120, a medium assembly 130 and a driving assembly 140. The shell assembly 110 has a cavity 111 and a magnetic surface 112, the magnetic surface 112 is suitable for carrying a magnetically attractable device, the direction perpendicular to the magnetic surface 112 is the first direction X, and the magnetic surface 112 is located on one side of the cavity 111 along the first direction X. The magnetic assembly 120 is located in the cavity 111, and the magnetic assembly 120 is used for providing a magnetic attraction force for attracting the magnetically attractable device, and the magnetic assembly 120 extends in a ring shape along the circumferential direction R around the first direction X. The medium assembly 130 extends in a ring shape along the circumferential direction R and faces the magnetic assembly 120, and when the medium assembly 130 is located around the magnetic assembly 120, the size of the magnetic attraction force can be changed. The driving assembly 140 is configured to drive the medium assembly 130 to adjust the relative position of the medium assembly 130 and the magnetic assembly 120. Compared with the traditional shielding material setting mode in the related art, the magnetic assembly 120 and the medium assembly 130 of the utility model both extend in a ring shape, which on the one hand makes the medium assembly 130 not affect the movement of the magnetic assembly 120 along the first direction X after being arranged opposite to the magnetic assembly 120, and the magnetic assembly 120 can maintain a ring shape without changing the structural shape of the ring-shaped magnetic assembly 120 for the arrangement of the medium assembly 130; on the other hand, the medium assembly 130 and the magnetic assembly 120 are both ring-shaped structures, which can make the adaptability of the two stronger, and the medium assembly 130 has a better magnetic attraction force adjusting effect. Therefore, the medium assembly 130 of the magnetic connection device 100 of the utility model can be used to adjust the size of the magnetic attraction force, and the structure and the arrangement position of the medium assembly 130 are reasonable, so that the medium assembly 130 is more easily adapted to the structure and the movement form of the magnetic assembly 120.

[0052] The specific movement mode of the first medium assembly 130 will be introduced below, referring to Figures 1-5In some embodiments, the medium assembly 130 is a magnetic shielding medium assembly 130, that is, at least part (the part for affecting the magnetic attraction force) of the material of the medium assembly 130 is a magnetic shielding material, for example, the material of the medium assembly 130 can be ferrite. The driving assembly 140 is configured to drive the medium assembly 130 to switch positions between a first position and a second position along the first direction X, when the medium assembly 130 is in the first position, the medium assembly 130 and the magnetic assembly 120 have a facing area S1 along a radial direction perpendicular to the first direction X, when the medium assembly 130 is in the second position, the medium assembly 130 and the magnetic assembly 120 have a facing area S2 along the radial direction perpendicular to the first direction X, and S1 < S2 is satisfied. The facing area of the medium assembly 130 and the magnetic assembly 120 along the radial direction perpendicular to the first direction X is defined as follows: the total area of the part where the projection of each part of the medium assembly 130 along the radial direction and the projection of the magnetic assembly 120 along the radial direction can coincide. According to the above description, since S1 < S2, when the medium assembly 130 is in the first position, the medium assembly 130 and the magnetic assembly 120 have a larger facing area with each other (at this time, the medium assembly 130 can completely cover the magnetic assembly 120 along the radial direction), so that the magnetic attraction force generated by the magnetic connection device 100 on the magnetically attractable device is larger, at this time, it can correspond to the normal use state of the magnetic connection device 100 fixedly connecting the magnetically attractable device, when the medium assembly 130 is in the second position, the medium assembly 130 and the magnetic assembly 120 have a smaller facing area with each other, so that the magnetic attraction force generated by the magnetic connection device 100 on the magnetically attractable device is smaller, at this time, it can correspond to the state that the magnetic connection device 100 can easily remove the magnetically attractable device. In addition, S1 can be equal to 0, at this time, the medium assembly 130 and the magnetic assembly 120 are completely staggered along the first direction X, that is, there is no part of the medium assembly 130 and the magnetic assembly 120 along the radial direction. Compared with the arrangement mode that the medium assembly 130 faces the magnetic assembly 120 along the first direction X, the above-mentioned embodiment makes the medium assembly 130 face the magnetic assembly 120 along the radial direction, and the medium assembly 130 can be sleeved on the inside or outside of the magnetic assembly 120, so that the arrangement of the medium assembly 130 can effectively utilize the space of the inside or outside of the magnetic assembly 120 extending along the circumferential direction R, while not affecting the movement of the magnetic assembly 120

[0053] For the specific structure and cooperation mode of the medium assembly 130, see Figures 1-5In some embodiments, the medium assembly 130 includes a medium support 131 and a plurality of medium bodies 132 for changing the magnitude of the magnetic attraction force, each of the medium bodies 132 is connected to the outer side of the medium support 131 and is spaced apart along the circumferential direction R. In order to facilitate the movement of each of the medium bodies 132, in some embodiments, the medium support 131 is sleeved on the inner side of the magnetic assembly 120, and the driving assembly 140 is connected to the medium support 131 to drive the plurality of medium bodies 132 to move synchronously relative to the magnetic assembly 120. It can be understood that the medium bodies 132 are components for affecting the magnetic attraction force, and the medium support 131 can fixedly connect the plurality of medium bodies 132, when the medium support 131 is driven by the driving assembly 140, the plurality of medium bodies 132 are simultaneously driven by the medium support 131, and the relative positions between each of the medium bodies 132 and the magnetic assembly 120 are changed. More specifically, in some embodiments, the driving assembly 140 is threadedly connected to the medium support 131, the medium support 131 is slidingly connected to the housing assembly 110, and the driving assembly 140 is configured to rotate along the circumferential direction R and drive the medium assembly 130 to slide along the first direction X. Specifically, the medium support 131 is threadedly connected to the driving assembly 140, and the medium support 131 and the housing assembly 110 form a sliding connection along the first direction X and limit the rotation of the medium support 131 along the circumferential direction R, so that the driving assembly 140 rotates along the circumferential direction R while the medium assembly 130 slides along the first direction X. According to the above threaded connection, the driving assembly 140 is more convenient to generate a driving effect, and the corresponding relationship between the driving effect (the number of rotation of the driving assembly 140) and the sliding distance of the medium support 131 is more controllable, and the magnetic attraction force is more convenient to adjust accurately.

[0054] In order to facilitate the user to control the driving assembly 140, referring to Figures 3-4In some embodiments, based on the threaded connection arrangement described above, the housing assembly 110 has an operation through hole 113 that communicates the cavity 111 with the outside, one end of the drive assembly 140 is rotationally connected to the housing assembly 110 along the first direction X, and the other end of the drive assembly 140 extends through the operation through hole 113 and out of the housing assembly 110. Specifically, the rotational connection between the drive assembly 140 and the housing assembly 110 can be implemented as follows: the drive assembly 140 is generally disc-shaped as a whole, the housing assembly 110 has an annular groove inside that is adapted to the outer contour of the disc-shaped drive assembly 140, the drive assembly 140 is rotationally located in the annular groove, and the groove surfaces on both sides of the annular groove along the first direction X can limit the displacement of the drive assembly 140 along the first direction X. Through the above arrangement, the user can conveniently control the drive assembly 140 while the structure and assembly method of the drive assembly 140 are more reasonable and simple, which is conducive to ensuring the compactness of the magnetic connection device 100. In order to hinder the magnetic attraction, the operation through hole 113 can be located at the other end surface of the housing assembly 110 away from the magnetic surface along the first direction X.

[0055] The following describes the specific movement mode of the second medium assembly 130. Referring to FIG. 2, the second medium assembly 130 is located in the first position, and the drive assembly 140 is located in the first position. Figures 6-8 In some embodiments, the medium assembly 130 is a magnetic shielding medium assembly 130, and the drive assembly 140 is configured to drive the medium assembly 130 to switch between the first position and the second position along a direction perpendicular to the first direction X (the specific form of the movement direction is not limited, the movement direction can not be radial, and the movement trajectory can be a straight line or a curve). When the medium assembly 130 is located in the first position, the facing area between the medium assembly 130 and the magnetic assembly 120 along the first direction X is S1, and when the medium assembly 130 is located in the second position, the facing area between the medium assembly 130 and the magnetic assembly 120 along the first direction X is S2, and S1 < S2 is satisfied. It can be understood that the above arrangement is similar to the specific movement mode of the first medium assembly 130 described in the foregoing embodiments, and the difference lies in the movement direction of the medium assembly 130 during the switching between the first position and the second position. In this embodiment, the medium assembly 130 moves along a direction perpendicular to the first direction X, and correspondingly, the change in the facing area between the medium assembly 130 and the magnetic assembly 120 in the first position and the second position corresponds to the facing area along the first direction X. Hereinafter, the facing area between the medium assembly 130 and the magnetic assembly 120 along the first direction X is defined as follows: the total area of the parts of the medium assembly 130 that can coincide with the projection of the magnetic assembly 120 along the first direction X.

[0056] For the specific structure and fitting form of the medium assembly 130, based on the definition of the medium support 131 and the medium body 132 in the foregoing embodiments, see Figures 6-8 In some embodiments, the driving assembly 140 is configured to rotate along the circumferential direction R and drive each medium body 132 to slide along the length direction of the sliding groove 114.

To achieve the above purpose, in some embodiments, the medium assembly 130 further comprises a plurality of medium connectors 133, each medium connector 133 is fixedly connected to the medium body 132 one by one, each medium connector 133 comprises a first protruding shaft 1331, the driving assembly 140 is fixedly connected to the medium support 131, the medium support 131 is rotationally connected to the shell assembly 110, the medium support 131 is provided with a plurality of second protruding shafts 1311 and a plurality of connecting members 1312, the shell assembly 110 is provided with a plurality of sliding grooves 114, the number of the first protruding shaft 1331, the second protruding shaft 1311, the connecting member 1312 and the sliding groove 114 is equal and one-to-one corresponding, along the radial direction perpendicular to the first direction X, one end of the connecting member 1312 away from the rotation axis of the medium support 131 is rotationally connected to one end of the first protruding shaft 1331 along the first direction X close to the magnetic surface 112, one end of each connecting member 1312 close to the rotation axis is rotationally connected to the second protruding shaft 1311, one end of the first protruding shaft 1331 along the first direction X away from the magnetic surface 112 extends into the sliding groove 114, and the driving assembly 140 is configured to rotate along the circumferential direction R and drive each medium body 132 to slide along the length direction of the sliding groove 114. Among them, the shape and size of the medium connector 133 and the medium body 132 can be similar or the same as the shape and size of the magnetic assembly 120, the medium support 131 can specifically be disc-shaped, the length direction of the plurality of sliding grooves 114 is the radial direction corresponding to the rotation axis of the medium support 131, the plurality of sliding grooves 114 are track-shaped (slot bodies with a waist-shaped hole cross section), and the plurality of sliding grooves 114 are uniformly distributed along the circumferential direction R.

[0057] In order to facilitate the user to control the driving assembly 140, see Figures 6-8 In some embodiments, the shell assembly 110 has an operation through hole 113 communicating the containing cavity 111 with the outside, one end of the driving assembly 140 is fixedly connected to the medium support 131, the other end penetrates the operation through hole 113 and extends out of the shell assembly 110 along the first direction X. In order to hinder the magnetic attraction, the operation through hole 113 can be located at the other side end surface of the shell assembly 110 away from the magnetic surface along the first direction X.

[0058] See Figures 6-8In some embodiments, the magnetic assembly 120 comprises a plurality of magnetic pieces 121, each of which has a fan ring structure, and each of which is arranged along a circumferential direction R to collectively form a circular ring-shaped magnetic assembly 120. In the radial direction, the polarity of each magnetic piece 121 facing one end of the medium assembly 130 is repulsive to the polarity of each magnetic piece 121 facing away from the other end of the medium assembly 130. It should be noted that the polarity of each magnetic piece 121 facing one end of the medium assembly 130 and the polarity of each magnetic piece 121 facing away from the other end of the medium assembly 130 can be separately arranged or separately manufactured and then connected to form an integrated structure. According to the above arrangement, the polarity array form of the magnetic assembly 120 can be adapted to the magnet array of the Magesafe magnetic ring of the Apple mobile phone. The user can select the movement mode of the medium assembly 130 according to the needs, so that the effect of changing the size of the magnetic force is better. The above embodiments do not limit the movement mode of the medium assembly 130, that is, the specific movement mode of the first or second medium assembly 130 described above can be applied.

[0059] Referring to Figure 1 and Figure 5In some embodiments, the medium assembly 130 is adapted to have a first end surface 134 facing one side of the magnetically attractable device along the first direction X when the medium assembly 130 is in the first position and / or the second position. The first end surface 134 can be a flat surface or a curved surface. The first end surface 134 can be a complete surface or can include a plurality of surfaces spaced apart from each other. In the following description, at least one of the surfaces satisfies the defined condition. Based on the above definition of the first end surface 134, for the position switching effect described above, in some embodiments, the first end surface 134 is parallel to the magnetic attraction surface 112 (when the first end surface 134 is a curved surface, one tangent plane of the outer periphery of the first end surface 134 is parallel to the magnetic attraction surface 112) when the medium assembly 130 is in the first position and / or the second position. In this case, the first end surface 134 can support the magnetically attractable device together with the magnetic attraction surface 112. In the above parallel state, when the medium assembly 130 is switched to the first position, the first end surface 134 is located on the side of the magnetic attraction surface 112 close to the magnetic assembly 120 along the first direction X. In this case, the first end surface 134 no longer supports the magnetically attractable device. In contrast to the above embodiment, in other embodiments, the first end surface 134 is located on the side of the magnetic attraction surface 112 close to the magnetic assembly 120 along the first direction X during the position switching of the medium assembly 130 between the first position and the second position (or during the entire movement of the medium assembly 130), and is not parallel to the magnetic attraction surface 112. Alternatively, in other embodiments, the first end surface 134 is parallel to the magnetic attraction surface 112 when the medium assembly 130 is in the first position, and the first end surface 134 is located on the side of the magnetic attraction surface 112 away from the magnetic assembly 120 along the first direction X when the medium assembly 130 is in the second position. In this case, the first end surface 134 can support and lift the magnetically attractable device away from the magnetic attraction surface 112, thereby further reducing the magnetic attraction force.

[0060] The second aspect of the embodiments of the utility model also provides an electronic device support, the electronic device support includes the magnetic connection device 100 of any one of the above embodiments. In addition to the supporting effect on the electronic device, the electronic device support can also have other effects. Therefore, taking the electronic device as an example of a mobile phone, the electronic device support can be one of a mobile phone fixing support (used for fixing on a desktop, a vehicle, or any suitable scene), a support accessory connected to the back of the mobile phone, a magnetically attractable power bank, a magnetically attractable wireless charger, and a selfie stick. In this case, the magnetically attractable device includes any type of electronic device.

[0061] In some embodiments, the magnetic connection device 100 is the whole of the electronic device support; in other embodiments, the electronic device support comprises a plurality of components, and the magnetic connection device 100 can be one of the components, and the plurality of components can be mechanically connected to each other or spaced apart from each other. For example, when the magnetically attractable device is a mobile phone, and the electronic device support is a magnetically attractable wireless charger, the magnetic connection device 100 is a module for fixing and supporting the mobile phone, and the electronic device support further comprises a charging module, and the charging module is electrically connected to the magnetic connection device 100, so that the electronic device support can supply power to the mobile phone while supporting the mobile phone.
