Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0041] In order to make the user more labor-saving action of separating the magnetizable device from the magnetic support, without changing the maximum magnetic force of the magnetic support, the related art adopts the mode of driving the magnet in the magnetic support to move, and adjusts the size of the magnetic force by changing the relative position or angle between the magnet and the attracted object. However, the magnet in the related art is difficult to disassemble and replace, and the driving structure for driving the magnet often cannot realize large stroke driving, so that the magnetic force adjusting ability is limited. At the same time, corresponding to different models, sizes and materials of the magnetizable device or different use scenarios, the size of the magnetic force required is also different. Therefore, the flexibility of the magnetic support in the related art in practical application is poor.

[0042] In view of this, see Figures 1-5The 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 enable it to be magnetically attracted and fixed, and the magnetically attractable equipment can be specifically mobile phone or tablet computer.Magnetic connecting device 100 can be fixed only by the action of magnetic attraction force, and can also be fixed by acting together with other forces (such as supporting force, clamping force, etc.).According to actual application scene, magnetic connecting device 100 itself can be fixed in different forms, for example, in desktop environment, magnetic connecting device 100 can be placed directly on the desktop;In the car environment, magnetic connecting device 100 can be fixed on the vehicle by its own clamping mechanism or magnetic attraction mechanism;In addition, magnetic connecting device 100 can also be directly or indirectly held by the user, and at this time, magnetic connecting device 100 can be a support accessory connected to the back of the mobile phone, or be used for the fixed connection between selfie stick and mobile phone.In addition, the relative orientation reference relationship between magnetic connecting device 100 (including any part) and the magnetically attractable equipment described in the utility model, unless otherwise specified, is the positional relationship in the specific attitude after the magnetically attractable equipment is magnetically attracted and fixed by magnetic connecting device 100.

[0043] Specifically, referring to Figures 1-5 Magnetic connecting device 100 includes shell assembly 110, magnetic assembly 120 and driving assembly 130.Shell assembly 110 has cavity 111 and magnetic surface 112, and magnetic surface 112 is suitable for carrying magnetically attractable equipment.The direction perpendicular to magnetic surface 112 is defined as first direction X, and second direction Y is perpendicular to first direction X.Magnetic surface 112 is located on one side of cavity 111 along first direction X.Cavity 111 is the inner cavity of shell assembly 110 itself, and magnetic surface 112 is the outer wall surface of one side of shell assembly 110.

[0044] Referring to Figures 1-5 Magnetic assembly 120 and medium assembly are located in cavity 111, and magnetic assembly 120 is used to provide magnetic attraction force to attract magnetically attractable equipment.Combined with the previous setting of shell assembly 110, when the user needs to magnetically attract and fix the magnetically attractable equipment, the magnetically attractable equipment can be placed on magnetic surface 112, and at this time, under the action of magnetic attraction force of magnetic assembly 120, the magnetically attractable equipment is attached to magnetic surface 112, so that the magnetically attractable equipment can be fixed on magnetic connecting device 100.It should be noted that the attachment effect described in the utility model needs to exclude the influence of error and micro gap.

[0045] Based on the above setting of the magnetic assembly 120 and the fixed assembly, the magnetic connection device 100 has a first state and a second state, in the first state, the magnetic assembly 120 can generate a magnetic attraction force F1 to the magnetically attractable device, in the second state, the magnetic assembly 120 can generate a magnetic attraction force F2 to the magnetically attractable device, and F1>F2. The first state can correspond to the normal use state of the magnetic connection device 100 fixedly connected to the magnetically attractable device, and the second state corresponds to the state of reducing the magnetic attraction force to facilitate the removal of the magnetically attractable device. For the specific switching form of the magnetic attraction force in different states, please refer to the following. The magnetic connection device 100 can change the magnetic attraction force in any suitable way, for example: in one way, the magnetic assembly 120 includes a jacking structure that can be movably arranged, the jacking structure can drive the magnetically attractable device to move away from the magnetic attraction surface 112; in another way, at least part of the magnetic assembly 120 is movably arranged, and the magnetic assembly 120 changes the position relative to the magnetically attractable device after moving, thereby changing the magnetic attraction force; in another way, the magnetic assembly 120 includes an electromagnet, and the magnetic connection device 100 changes the magnetic attraction force by changing the on-off state or electrical parameters of the electromagnet. In addition, the action of switching the magnetic connection device 100 between the first state and the second state can be completed by the magnetic connection device alone, or by the external driving force and the magnetic connection device together.

[0046] In particular, in order to make the magnetic assembly 120 more convenient to disassemble, replace or adjust, see Figures 1-2 In the first disassembly configuration form, the shell assembly 110 further includes a first disassembly part 114, the first disassembly part 114 has a first position and a second position, when the first disassembly part 114 is located at the first position, the first disassembly part 114 covers the mounting opening 1131, at this time, it can correspond to the normal use state of the magnetic connection device 100, and the first disassembly part 114 will not affect the use of the magnetic connection device 100; when the first disassembly part 114 is located at the second position, at least part of the mounting opening 1131 is exposed, that is, at least part of the mounting opening 1131 is no longer covered and shielded by the first disassembly part 114, at this time, the user can more conveniently disassemble and adjust the magnetic assembly 120. The user can control the position switching of the first disassembly part 114 between the first position and the second position, which can be direct driving by the user directly contacting and driving the first disassembly part 114, or indirect driving through transmission structure or electric driving structure.

[0047] In addition, in the second disassembly configuration form, the shell assembly 110 further includes a second disassembly part, which is configured to drive at least part of the magnetic assembly 120 to extend out of the mounting opening 1131 and into the cavity 111. The above setting can also facilitate the user to disassemble and adjust the magnetic assembly 120, and does not need to be operated in a stretching mode, and the operation space is larger.

[0048] The two configuration forms described above can be used simultaneously, so that the first dismounting part 114 can be switched between the first position and the second position, and when in the second position, at least part of the magnetic assembly 120 is extended out of the cavity 111 through the second dismounting part, so that the adjustment operation of the magnetic assembly 120 is more convenient.

[0049] It can be seen that the magnetic connection device 100 of the utility model includes a shell assembly 110 and a magnetic assembly 120. The shell assembly 110 has a cavity 111 and a magnetic surface 112 suitable for bearing a magnetically attractable device, the magnetic surface 112 is suitable for bearing a magnetically attractable device, the direction perpendicular to the magnetic surface 112 is the first direction X, the magnetic surface 112 is located on one side of the cavity 111 along the first direction X, and the shell assembly 110 includes a shell main body 113, and the shell main body 113 has a mounting opening 1131 communicating the cavity 111 with the outside. The magnetic assembly 120 is located in the cavity 111, and the magnetic assembly 120 is suitable for generating a magnetic attraction force on the magnetically attractable device; the magnetic connection device 100 has a first state and a second state, in the first state, the magnetic assembly 120 can generate a magnetic attraction force F1 on the magnetically attractable device, in the second state, the magnetic assembly 120 can generate a magnetic attraction force F2 on the magnetically attractable device, and F1>F2 is satisfied. The shell assembly further includes a first dismounting part 114, the first dismounting part 114 has a first position and a second position, when the first dismounting part 114 is located in the first position, the first dismounting part 114 covers the mounting opening 1131, and when the first dismounting part 114 is located in the second position, the mounting opening 1131 is at least partially exposed; and / or, the shell assembly 110 further includes a second dismounting part, and the first dismounting part 114 is configured to drive at least part of the magnetic assembly 120 to extend out of the cavity 111 through the mounting opening 1131. Compared with the magnet setting form which is difficult to dismount and replace in the related art, in the utility model scheme, through the setting of the first dismounting part 114 and / or the second dismounting part, the adjustability of the magnetic assembly 120 is higher, and the user's adjustment operation on the magnetic assembly 120 is more convenient.

[0050] The first dismounting configuration form is further described below, referring to Figures 1-5In some embodiments, the first detachable part 114 has a first position and a second position, when the first detachable part 114 is in the first position, the first detachable part 114 covers the mounting opening 1131, when the first detachable part 114 is in the second position, the mounting opening 1131 is at least partially exposed, when the first detachable part 114 is in the first position, the first detachable part 114 is magnetically connected with the shell main body 113, after the magnetic connection between the first detachable part 114 and the shell main body 113 is released, the first detachable part 114 can move from the first position to the second position. The first detachable part 114 can extend outward relative to the shell main body 113 by a part, so that the user can apply force to the above-mentioned extending part, thereby making the separation of the first detachable part 114 and the shell main body 113 more convenient. In other embodiments, when the first detachable part 114 is in the first position, other detachable connection modes can also be used between the first detachable part 114 and the shell main body 113, such as through buckling to form a buckle connection, or to form a threaded connection, or to be fixed by a rotating buckle, or to be fixed by a pressing buckle, etc.

[0051] For the movement structure of the first detachable part 114, see Figures 4-5 In some embodiments, the shell assembly 110 has a mounting hole 115, the first detachable part 114 includes a shaft body 1141, along a second direction Y perpendicular to the first direction X, the shaft body 1141 is arranged in the mounting hole 115, so that the first detachable part 114 can rotate relative to the shell main body 113 and switch positions between the first position and the second position. Through the above-mentioned arrangement, the first detachable part 114 can be used as a flip cover structure of the shell main body 113, when the first detachable part 114 is in the first position, the first detachable part 114 can be arranged on one side (specifically, the upper side) of the shell main body 113, after the first detachable part 114 is flipped, the first detachable part 114 can be limited by the abutting structure between the mounting hole 115 and the shaft body 1141, or by other fixing structures, or by the user's force, so that the first detachable part 114 can be stably located in the second position. More specifically, in some embodiments, the shell assembly 110 has an end wall 1132, the end wall 1132 and the first detachable part 114 are adapted to face the side of the magnetically attractable device to jointly define a magnetic attraction surface 112 (at this time, the two are parallel, so that the magnetic attraction surface 112 is a plane, which is more suitable for placing the magnetically attractable device), the shell assembly 110 includes a through hole structure 1133 connected to the side of the end wall 1132 facing the cavity 111, the through hole structure 1133 has the mounting hole 115, the first detachable part 114 includes a rotating structure 1142, the rotating structure 1142 forms an avoiding space 1143 (in the avoiding space 1143, the first detachable part 114 can be arranged in the second position, and the first detachable part 114 can be arranged in the first position when the first detachable part 114 is in the avoiding space 1143), the rotating structure 1142 is arranged in the avoiding space 1143, and the rotating structure 1142 is arranged in the avoiding space 1143. Figures 1-5In the shown embodiment, the rotating structure 1142 is in a "U" shape, the avoiding space 1143 is a space formed by the middle region of the "U" shape, the shaft body 1141 penetrates the rotating structure 1142, the perforated structure 1133 and the rotating structure 1142 are both located in the cavity 111 when the first dismounting part 114 is in the first position, the rotating structure 1142 extends out of the cavity 111 and the end wall 1132 extends into the avoiding space 1143 during the movement of the first dismounting part 114 from the first position to the second position. Through the above position setting of the perforated structure 1133 and the rotating structure 1142, both of them can be hidden in the cavity 111 in the first state, which is more beautiful and will not interfere with the normal work of the magnetic connection device 100. During the rotation of the first dismounting part 114, the avoiding space 1143 can be set to prevent the rotating structure 1142 from interfering with the end wall 1132. For example, in the second position, the first dismounting part 114 can be flipped open by 90 to 120 degrees relative to the magnetic surface 112.

[0052] In addition to the manual operation of the user to drive the first dismounting part 114, other structures can be used to assist in driving the first dismounting part 114. For example, in some embodiments, the shaft body 1141 can be connected to a torsional spring, and the other end of the shaft body 1141 is provided with a pressing buckle. In the first position, the pressing buckle locks the relative position of the first dismounting part 114 and the shell assembly 110. When it is necessary to switch the position, the user presses the pressing buckle to release the lock, thereby achieving the pressing and popping out of the first dismounting part 114.

[0053] In order to make it more convenient for the user to adjust the magnetic assembly 120, see Figure 2 In some embodiments, when the first dismounting part 114 is in the second position, the mounting opening 1131 is at least partially exposed, and the opening profile of the mounting opening 1131 is located outside the magnetic assembly 120 along the axis direction of the mounting opening 1131. The above limitation is that the normal projection of the opening profile of the mounting opening 1131 on the projection plane perpendicular to the first direction X covers the normal projection of the magnetic assembly 120 on the projection plane. In some embodiments, the magnetic assembly 120 includes a mounting shell 121 and a magnetic piece 122, and the magnetic piece 122 is contained in the mounting shell 121. At this time, the opening profile of the mounting opening 1131 can be located outside the mounting shell 121 and the magnetic piece 122; or the opening profile of the mounting opening 1131 can be located outside the magnetic piece 122, and the outer profile of the mounting shell 121 can be located outside the opening profile of the mounting opening 1131.

[0054] In order to realize the state switching of the magnetic connection device 100, see Figures 4-5In some embodiments, the magnetic connection device 100 further comprises a driving assembly 130, which is rotationally connected to the housing assembly 110 and threadedly connected to the magnetic assembly 120, which is slidingly connected to the housing assembly 110. During the driving of the magnetic assembly 120 by the magnetic assembly 120, the driving assembly 130 rotates along the circumferential direction of the first direction X, and the rotation axis is parallel to the first direction X, and drives the magnetic assembly 120 to slide along the first direction X. It can be understood that the driving assembly 130 can drive the magnetic assembly 120 to reciprocate along the first direction X by rotation, thereby playing a role in adjusting the magnetic attraction force. Specifically, the driving assembly 130 can rotate in place without changing the overall position. Since the driving assembly 130 is threadedly connected to the magnetic assembly 120, and the magnetic assembly 120 is slidingly connected to the housing assembly 110 along the first direction X, the driving assembly 130 drives the magnetic assembly 120 to move along the first direction X while rotating in the forward and reverse directions. In order to facilitate user control of the driving assembly 130, in some embodiments, the housing assembly 110 has an operation through hole communicating with the cavity 111 and the outside, and at least part of the driving assembly 130 is arranged in the operation through hole and extends out of the housing, and the user can rotate the driving assembly 130 extending out of the housing.

[0055] More specifically, referring to Figures 4-5 In some embodiments, the magnetic assembly 120 comprises a mounting shell 121 and a magnetic piece 122, the magnetic piece 122 is suitable for generating a magnetic attraction force on the magnetically attractable device, the mounting shell 121 comprises a first shell 1211 and a second shell 1212 which are detachably connected to each other, the detachable connection between the first shell 1211 and the second shell 1212 can include snap connection, threaded connection, magnetic attraction connection, etc., the first shell 1211 accommodates the magnetic piece 122, and the second shell 1212 is slidingly connected to the housing assembly 110. By setting the two as detachable connection, the first shell 1211 and the magnetic piece 122 can be collectively separated from the second shell 1212, so that the disassembly and assembly operation is more convenient. The mounting manner between the mounting shell 121 and the magnetic piece 122 can be clearance fit or interference fit. The mounting shell 121 can form a mounting groove 1213, and the mounting groove 1213 can have a groove opening facing the magnetic surface 112 along the first direction X, so that the shape of the mounting groove 1213 can be adapted to the shape of the magnetic piece 122, and the user can conveniently take out or place the magnetic piece 122 from the mounting groove 1213. Based on the setting of the mounting shell 121, in some embodiments, the number of magnetic pieces 122 is multiple, the mounting shell 121 forms a mounting groove 1213, the mounting groove 1213 has a groove opening facing the magnetic surface 112 along the first direction X, each magnetic piece 122 is accommodated in the mounting groove 1213, and the shape and size of each magnetic piece 122 can be the same or different; according to the demand, in other embodiments, the number of magnetic pieces 122 is one.Figure 5 In the shown embodiment, each magnetic piece 122 has a fan ring structure, the magnetic pieces 122 are arranged in a circumferential direction, and the mounting shell 121 also has a ring structure, so as to form a ring-shaped magnetic assembly 120.

[0056] In addition to the above-mentioned driving mode of the magnetic assembly 120 through threaded connection and sliding connection, other driving modes can also be used to drive the magnetic assembly 120, for example, in some other embodiments, a wedge-shaped inclined surface structure can be used to realize the rotation and lifting of the magnetic assembly 120, or a lever principle can be used to realize the lifting of the magnetic assembly 120 by using a connecting rod.

[0057] The second disassembly configuration form is further described below. In some embodiments, the second disassembly part is configured to drive at least part of the magnetic assembly 120 to extend out of the mounting opening 1131 to the cavity 111. The cavity 111 includes a receiving groove extending along a second direction Y perpendicular to the first direction X, and one end of the receiving groove is communicated with the mounting opening 1131. The wall surface where the mounting opening 1131 is located is adjacent to the wall surface where the magnetic attraction surface 112 is located. It can be understood that the receiving groove is part of the cavity 111, and the receiving groove is independent of other parts of the cavity 111 and is used as a space for receiving the magnetic assembly 120. The mounting opening 1131 can be located on the side wall of the shell assembly 110, and the magnetic attraction surface 112 can be located on the end wall 1132 of the upper and lower sides of the shell assembly 110, so that the arrangement of the mounting opening 1131 and the receiving groove affects the support and adsorption effect of the magnetic attraction surface 112. It should be noted that the driving mode of the second disassembly part to the magnetic assembly 120 can be direct driving or indirect driving. When it is direct driving, the second disassembly part is driven or responds to the driving signal to directly push the magnetic assembly 120. When it is indirect driving, the second disassembly part does not directly push the magnetic assembly 120. At this time, the second disassembly part can be a sliding groove and forms a sliding connection with the magnetic assembly 120. When the magnetic assembly 120 is driven, the magnetic assembly 120 slides out of the receiving groove. The action of the above-mentioned driving force can be specifically as follows: the user inserts fingers into the mounting opening 1131, and through the sliding connection between the magnetic assembly 120 and the second disassembly part, the magnetic assembly 120 is pulled out of the receiving groove.

At this time, the magnetically attractable device includes any type of electronic device. In addition to the supporting effect on the electronic device, the electronic device support can also have other effects, so taking the electronic device as a mobile phone as an example, 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.
