[0010] In some embodiments, the knob has a recess on the side facing the first opening, the recess having a first threaded structure extending toward the receiving member, and the receiving member has a second threaded structure on the side facing the second opening, the second threaded structure being inserted into the recess and threadedly connected to the first threaded structure.

[0011] In some embodiments, the knob has an extension structure extending in a direction perpendicular to the first direction on the side facing the first opening, the housing includes a first housing and a second housing disposed opposite to each other in the first direction, and the extension structure is engaged between the first housing and the second housing and is rotatable relative to the first housing and the second housing.

[0012] In some embodiments, the first housing has a supporting portion extending along the first direction on the side facing the second opening. The supporting portion contacts the side of the extension structure opposite to the second opening on the side facing the second opening. The extension structure contacts the second housing on the side facing the second opening. The second housing has a stop edge extending along the first direction on the side opposite to the second opening. The direction perpendicular to the first direction is the second direction. The stop edge and the supporting portion are offset in the second direction. The side of the stop edge along the second direction contacts the side of the extension structure along the second direction on the side of the extension structure along the second direction. The extension structure is configured to be movable relative to the supporting portion and the stop edge.

[0013] In some embodiments, the first housing and the second housing together define a cavity located on the side of the abutment away from the receiving member. The first housing has a first connecting portion in the cavity, and the second housing has a second connecting portion in the cavity, the second connecting portion being connected to the first connecting portion.

[0014] In some embodiments, the first housing is provided with a first limiting structure on one side of the receiving cavity, and the receiving member is provided with a second limiting structure on the side facing the first housing. The second limiting structure is engaged with the first limiting structure and can move relative to the first limiting structure along the first direction.

[0015] In some embodiments, the number of first limiting structures is multiple, and each first limiting structure is spaced apart. The number of second limiting structures is multiple, and each second limiting structure is engaged between adjacent first limiting structures.

[0016] In some embodiments, the magnetic connection device further includes a first fixing member and a second fixing member. The first fixing member is connected to the side of the receiving member opposite to the second opening. The side of the second magnetic member facing the second opening is connected to the receiving member.

[0018] A second aspect of this utility model also provides a magnetic holder, comprising:

[0019] The magnetic connection device described in any of the above embodiments; and

[0020] An adapter, connected to the magnetic connection device and adapted to connect to an external device.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] In the technical solution of this utility model, the magnetic connection device includes a first magnetic element, a second magnetic element, a housing, and an adjustment assembly. Both the first and second magnetic elements can be used to attract electronic devices, and the second magnetic element is arranged spaced apart from the first magnetic element. The housing has a receiving cavity extending along a first direction, which has a first opening and a second opening. The first magnetic element is installed at the end of the housing located at the first opening. The adjustment assembly includes a knob and a receiving member disposed in the receiving cavity. The second magnetic element is installed on the side of the receiving member facing the first opening. One end of the knob protrudes from the receiving cavity through the second opening. The receiving member is threadedly connected to the knob. When the knob rotates relative to the housing, the receiving member moves along the first direction under the action of the thread, thereby adjusting the distance between the second and first magnetic elements. This allows the surface of the second magnetic element used to attract the electronic device to protrude beyond the surface of the first magnetic element used to attract the electronic device, or to be flush with the surface of the second magnetic element used to attract the electronic device, thus enabling effortless removal of the electronic device.

[0023] Compared to related technologies that use a single magnetic chuck to attract electronic devices, the first and second magnetic chucks in this application allow for flexible adjustment of the magnetic force. This ensures the stability of the connection while improving ease of use and safety, making it suitable for the reliable attraction of various electronic devices. Furthermore, this design reduces the difficulty of disassembling devices due to excessive magnetic force, extends the lifespan of the magnetic chucks, and optimizes the user experience. In addition, compared to the ejection structure used in related technologies to separate electronic devices from the magnetic chucks, this application, through the auxiliary attraction of the second magnetic chuck, effectively prevents the electronic device from falling after separation from the first magnetic chuck, ensuring a smooth transition during removal and preventing damage caused by sudden loss of magnetic force.

[0048] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] In view of this, please refer to Figures 1 to 9 This utility model provides a magnetic attraction device 100, which includes a first magnetic element 110, a second magnetic element 120, a housing 130, and an adjustment assembly 140. This magnetic attraction device 100 is designed for the detachable attraction of electronic devices, including but not limited to smartphones, tablets, and smartwatches. Specifically, both the first magnetic element 110 and the second magnetic element 120 are magnetic and capable of attracting electronic devices. Please refer to [link to relevant documentation]. Figure 2The second magnetic attractor 120 can be sleeved inside the first magnetic attractor 110, or it can be sleeved outside the first magnetic attractor 110. For ease of description, the following description uses the example of the second magnetic attractor 120 being sleeved inside the first magnetic attractor 110. The second magnetic attractor 120 and the first magnetic attractor 110 are spaced apart to ensure that there is no unnecessary physical interference or magnetic interference between them. In some embodiments, the first magnetic attractor 110 can be configured as a ring, and the second magnetic attractor 120 can be designed as a ring or a cylinder. The first magnetic attractor 110 can be composed of multiple magnet segments, and similarly, the second magnetic attractor 120 can also be composed of multiple magnet segments. In other embodiments, both the first magnetic attractor 110 and the second magnetic attractor 120 can be composed of a single complete ring-shaped magnet to ensure the stability and reliability of the magnetic connection.

[0051] Please see Figure 3 and Figure 5 The housing 130 has a receiving cavity 131 extending along a first direction X, the receiving cavity 131 having a first opening 132 and a second opening 133 in the first direction X. A first magnetic attractor 110 is installed on the side of the housing 130 near the first opening 132, thereby enabling effective contact and attraction with the electronic device. The adjustment assembly 140 consists of a knob 141 and a receiving member 142. The knob 141 is rotatably connected to the housing 130 and protrudes from the second opening 133, thus facilitating user operation of the knob 141. The receiving member 142 is connected to the knob 141 by a threaded connection, and a second magnetic attractor 120 is installed on the side of the receiving member 142 facing away from the knob 141. Thus, by rotating the knob 141, the receiving member 142 can drive the second magnetic attractor 120 to move along the first direction X, thereby enabling the electronic device to separate from or attract the first magnetic attractor 110, achieving the purpose of adjusting the magnetic attraction force and ensuring stable attraction and separation of the electronic device. The outer casing 130 can be made of materials including but not limited to metal, plastic, carbon fiber, etc., which have good wear resistance and impact resistance, ensuring the reliability of the device for long-term use.

[0052] Specifically, by rotating knob 141, the receiving member 142 can be moved relative to the housing 130 along the first direction X, thereby adjusting the position of the second magnetic member 120, moving it away from or closer to the first magnetic member 110. When the second magnetic member 120 moves away from the first magnetic member 110, it protrudes from the first magnetic member 110, weakening the magnetic attraction of the magnetic connection device 100 to the electronic device, facilitating easy separation of the electronic device. Furthermore, during the separation process of the first magnetic member 110 from the electronic device, the second magnetic member 120 provides an attractive force to the electronic device, preventing it from accidentally falling and being damaged after separation, thus improving the safety of the magnetic connection device 100. When the second magnetic member 120 is close to and flush with the first magnetic member 110, the magnetic connection device 100 provides sufficient attractive force to the electronic device, ensuring a secure connection.

[0053] Compared to the single magnetic attraction structure in related technologies, this application, through the design of the first magnetic attraction component 110 and the second magnetic attraction component 120, achieves flexible adjustment of the magnetic attraction force. This ensures the stability of the connection of electronic devices while improving ease of use and safety, making it suitable for the reliable attraction of various electronic devices. Simultaneously, this design reduces the difficulty of disassembling devices due to excessive magnetic attraction force, extends the service life of the magnetic attraction components, and optimizes the user experience. Furthermore, compared to the ejection structure designed in related technologies to facilitate the disassembly of electronic devices, which can push the electronic device away from the magnetic attraction component but easily causes the electronic device to lose its attraction force after separation, increasing the risk of falling, this application effectively avoids this problem through the auxiliary attraction of the second magnetic attraction component 120, ensuring the safety and stability of the electronic device during the separation process. When the second magnetic attraction component 120 and the first magnetic attraction component 110 are fully overlapped, the magnetic attraction force reaches its maximum, ensuring that the device will not fall off even under severe vibration. Furthermore, the knob 141 and the receiving part 142 are connected by a thread, giving the receiving part 142 a self-locking function for adjusting the second magnetic member 120, preventing accidental movement and further enhancing the stability and reliability of the device. Compared to the additional mechanical locking devices in related technologies, this application simplifies the structure and reduces manufacturing costs through the self-locking characteristic of the knob 141, while avoiding safety hazards caused by mechanical locking failure.

[0054] In addition, in this application, the first magnetic component 110 is mounted on the housing 130. Compared with the separate brackets used to fix the magnetic components in related technologies, this simplifies the overall structure, reduces the number of parts, lowers production costs, and improves the compactness and aesthetics of the device. It should be noted that the connection methods between the first magnetic component 110 and the housing 130 include, but are not limited to, adhesive bonding and snap-fit ​​connections. Similarly, the connection methods between the second magnetic component 120 and the receiving component 142 include, but are not limited to, adhesive bonding and snap-fit ​​connections. In some embodiments, the cross-section of the first magnetic component 110 can be designed as a "convex" shape, and the housing 130 has a corresponding groove to ensure a tight fit and enhance the adsorption force. To facilitate the installation of the first magnetic component 110, the groove has a clearance section. The first magnetic component 110 includes multiple "convex" structures, which can be inserted into the groove segment by segment from the clearance section and slid to a predetermined position. The clearance section ensures convenient installation without affecting the overall adsorption effect. Similarly, the second magnetic chuck 120 can also adopt a similar design to ensure a tight fit with the receiving part 142.

[0055] Please see Figure 3 , Figure 8 and Figure 9 To reduce the size of the magnetic connection device 100 in the first direction X, a cavity 1411 is provided on the side of the knob 141 facing the first opening 132. This cavity 1411 contains a first threaded structure 1412 extending towards the receiving member 142. Furthermore, a second threaded structure 1421 corresponding to the first threaded structure 1412 is provided on the side of the receiving member 142 facing the second opening 133. The second threaded structure 1421 can be inserted into the cavity 1411 and threadedly connected to the first threaded structure 1412. This design not only ensures precise control of the forward or backward movement of the receiving member 142 when the knob 141 is rotated, but also increases the stability of the entire adjustment assembly 140. To improve durability, lubricating material can be added between the first threaded structure 1412 and the second threaded structure 1421 to reduce frictional loss and extend service life. In addition, a self-locking thread design can be used to prevent the knob 141 from loosening on its own without external force, ensuring the stability of the magnetic connection device 100.

[0056] Specifically, in some embodiments, the first threaded structure 1412 can be a cylindrical structure with external threads, and the second threaded structure 1421 corresponds to an internally threaded hole. The two fit tightly together, ensuring that the receiving part 142 moves smoothly and stably when the knob 141 is rotated. In other embodiments, the first threaded structure 1412 can also be a hole-like structure with internal threads, and the second threaded structure 1421 corresponds to a cylindrical structure with external threads. The two also achieve a precise fit, ensuring that the movement of the receiving part 142 is both smooth and reliable when the knob 141 is operated.

[0057] Please see Figure 9 The knob 141 has an extension structure 1413 extending perpendicular to the first direction X on the side facing the first opening 132. To facilitate the assembly of the magnetic connection device 100, in some embodiments, the housing 130 includes a first housing 134 and a second housing 135, which are arranged opposite each other along the first direction X and can be fastened together. The extension structure 1413 of the knob 141 is engaged between the first housing 134 and the second housing 135 and can rotate freely relative to them. By engaging the extension structure 1413 inside the housing 130, not only is the overall structure compactness improved, but the stability and durability of the device are also enhanced. The first housing 134 and the second housing 135 can be securely connected by connection methods including but not limited to snap-fit, adhesive, and threaded connections, ensuring the overall structural compactness. To further enhance the user experience, the portion of the knob 141 protruding from the second opening 133 can be designed with an anti-slip texture to increase friction and prevent slippage during operation.

[0058] Please see Figure 3 and Figure 6 To further ensure the installation stability of the knob 141 while ensuring its smooth rotation, in some embodiments, the first housing 134 has a supporting portion 1341 extending along the first direction X on the side facing the second opening 133. The supporting portion 1341, facing the second opening 133, contacts the side of the extension structure 1413 opposite to the second opening 133, while the side of the extension structure 1413 facing the second opening 133 contacts the second housing 135. The supporting portion 1341 effectively prevents the knob 141 from displacing relative to the housing 130 along the first direction X, ensuring that the knob 141 remains stable during rotation and also reducing the noise of the magnetic connection device 100. It should be noted that the contact between the supporting portion 1341 and the extension structure 1413 can be separable or slidable to ensure the stability and smoothness of the knob 141 during rotation.

[0059] Please see Figure 3 and Figure 7 The second housing 135 has a stop 1351 extending along the first direction X on the side opposite to the second opening 133. The stop 1351 and the abutment 1341 are offset in the second direction Y perpendicular to the first direction X. The side of the stop 1351 along the second direction Y contacts the side of the extension structure 1413 along the second direction Y, thereby preventing the knob 141 from shifting during rotation. That is, the interaction between the stop 1351 and the extension structure 1413 effectively restricts the lateral movement of the knob 141, ensuring that the knob 141 rotates stably in the plane perpendicular to the first direction X, further improving the accuracy and reliability of the knob 141 operation.

[0060] To enhance structural stability, a small gap can be provided between the supporting part 1341 and the stop edge 1351, or the gap can be filled with an elastic material. This ensures smooth rotation of the knob 141 while preventing wear or loosening due to long-term use. Additionally, guide rails or grooves can be provided on the edge of the extension structure 1413, with corresponding structures on the supporting part 1341 and the stop edge 1351 that can mate with the guide rails or grooves. This ensures that the knob 141 rotates along a predetermined trajectory, making its rotation more precise and stable, further reducing friction and noise, and improving the user experience.

[0061] To ensure the reliable connection between the first housing 134 and the second housing 135, in some embodiments, please refer to... Figure 6 and Figure 7 The first housing 134 and the second housing 135 together define a cavity 136, which is located on the side of the supporting portion 1341 opposite to the receiving member 142, that is, on the side of the retaining edge 1351 opposite to the extension structure 1413. Within this cavity 136, the first housing 134 has a first connecting portion 1342, and the second housing 135 has a corresponding second connecting portion 1352. The first connecting portion 1342 and the second connecting portion 1352 are interconnected, ensuring the overall structural strength and stability of the outer casing 130. This design not only enhances the mechanical strength of the entire device but also allows the various components to work closely together, improving overall performance. Specifically, the first connecting structure can be a columnar structure extending along a first direction X; similarly, the second connecting structure can be a columnar hole structure matching the first connecting structure, and the two are connected by insertion or thread. In some embodiments, the first connecting structure has a threaded hole, and the second connecting structure has a through hole that extends through the second housing 135 along a first direction X. Thus, a bolt can be passed through the through hole and tightened into the threaded hole to achieve a secure connection between the first housing 134 and the second housing 135. To further improve the structural stability, additional support structures or reinforcing ribs can be added inside the cavity 136, particularly between the first connecting portion 1342 and the second connecting portion 1352, thereby increasing the overall compressive strength of the device.

[0062] Please see Figure 6 and Figure 8To ensure the stability of the movement of the receiving member 142 along the first direction X, in some embodiments, the first housing 134 is provided with a first limiting structure 1343 on one side of the receiving cavity 131, and the receiving member 142 is provided with a second limiting structure 1422 on the side facing the first housing 134. The second limiting structure 1422 can be slidably connected to the first limiting structure 1343 by a snap-fit ​​mechanism. Therefore, when the receiving member 142 moves along the first direction X, the second limiting structure 1422 can slide relative to the first limiting structure 1343 along the first direction X, thereby effectively limiting the lateral offset of the receiving member 142 and ensuring its smooth movement within a predetermined trajectory. It is understood that in some embodiments, the first limiting member may be provided with a guide groove, and the second limiting member may be provided with a matching guide protrusion. The guide protrusion can be inserted into the guide groove and can slide with the receiving member 142 along the first direction X, further improving the movement accuracy and stability of the receiving member 142.

[0063] The first housing 134 has multiple spaced-apart first limiting structures 1343 on one side of the receiving cavity 131. The receiving member 142 also has multiple second limiting structures 1422 on the side facing the first housing 134. Each second limiting structure 1422 can engage with an adjacent first limiting structure 1343, allowing it to move relative to the first limiting structure 1343 along a first direction X. This ensures that the receiving member 142 can be smoothly and accurately adjusted in position, while avoiding unnecessary lateral movement or offset. By increasing the number of first limiting structures 1343 and second limiting structures 1422, the accuracy and stability of the adjusting assembly 140 can be significantly improved, allowing the user to more precisely control the position of the second magnetic member 120.

[0064] To further enhance the limiting effect, an elastic element, such as a spring or rubber pad, can be introduced between the first limiting structure 1343 and the second limiting structure 1422 to provide additional cushioning and reduce wear caused by mechanical impact. In some embodiments, a plurality of first limiting structures 1343 can be arranged to form a serrated structure, with the second limiting structure 1422 tightly engaged between adjacent first limiting structures 1343, thereby forming a stable limiting mechanism.

[0065] To reduce the structural complexity of the first housing 134, in some embodiments, please refer to... Figure 6 The supporting portion 1341 and the first limiting portion can be integrated into a single structure. Specifically, the supporting portion 1341 can be an annular protrusion extending along the first direction X, which protrudes along the second direction Y to form the first limiting portion. This achieves the limiting function while simplifying the manufacturing process and reducing assembly and maintenance costs. Furthermore, this design effectively distributes stress and improves the overall structural durability.

[0066] Please see Figures 3 to 5 The magnetic connection device 100 also includes a first fixing member 150 and a second fixing member 160. The first fixing member 150 is connected to the side of the receiving member 142 facing away from the second opening 133. The side of the second magnetic member 120 facing the second opening 133 is connected to the receiving member 142, and the side of the second magnetic member 120 facing away from the first magnetic member 110 is connected to the side of the first fixing member 150 facing the first magnetic member 110. This allows the second magnetic member 120 to achieve a stable connection under the combined action of the receiving member 142 and the first fixing member 150, preventing the second magnetic member 120 from moving or even falling off during the movement of the receiving member 142. In addition, the second fixing member 160 is connected to the side of the second magnetic member 120 facing away from the receiving member 142, and the side of the second fixing member 160 facing away from the first magnetic member 110 is also connected to the first fixing member 150, further ensuring the reliability of the fixation of the second magnetic member 120. In other words, the arrangement of the receiving member 142 and the second fixing member 160 effectively restricts the movement of the second magnetic member 120 along the first direction X, thereby maintaining the stability and functionality of the overall device.

[0067] Understandably, after the second magnetic accumulator 120 is connected to the receiving member 142 and the first fixing member 150, the second fixing member 160 covers the side of the second magnetic accumulator 120 facing away from the receiving member 142, and one end of the second fixing member 160 along the second direction Y is connected to the first fixing member 150. This not only enhances the fixing effect of the second magnetic accumulator 120, but also facilitates the assembly of the second magnetic accumulator 120. It should be noted that the second fixing member 160 and the first fixing member 150 can be connected by methods including but not limited to welding, snap-fit, and integrated connection. Integrated connection includes but is not limited to injection molding and stamping.

[0068] Please see Figure 3 and Figure 4In some embodiments, the first fixing member 150 and the second fixing member 160 are manufactured independently and then assembled. The first fixing member 150 has a clearance groove 151 on the side facing the second magnetic member 120 and at the end opposite to the second opening 133. This clearance groove 151 design allows the second magnetic member 120 to be smoothly inserted between the first magnetic member 110 and the first fixing member 150, improving the ease of installation of the second magnetic member 120 and reducing friction and collision between the second magnetic member 120 and the first fixing member 150 during installation. Furthermore, the clearance groove 151 can also accommodate the end of the second fixing member 160 opposite to the first magnetic member 110. Specifically, one end of the second fixing member 160 can be completely embedded in the clearance groove 151, thereby ensuring the compactness and flatness of the entire device. In this way, it can be ensured that the side wall of the second fixing member 160 away from the second magnetic member 120 is flush with the side wall of the first fixing member 150 away from the second opening 133, which not only enhances the overall aesthetics of the appearance, but also avoids potential safety hazards or operational inconvenience caused by protruding parts.

[0069] It is understood that the connection between the first fixing member 150 and the receiving member 142 can be achieved by means including but not limited to bolts, screws, rivets, or adhesives. For ease of understanding, the connection between the two is illustrated by an example of a screw connection. The first fixing member 150 has a through hole extending along the first direction X, and the receiving member 142 has a corresponding threaded hole. The screw is inserted through the through hole and screwed into the threaded hole of the receiving member 142, thereby achieving a fixed connection between the two. To ensure the reliability of the connection, multiple screws can be used for fixing. Specifically, three screws can be used for fixing, and the three screws can be distributed in a triangular shape to ensure uniform force distribution on the connection. In some embodiments, to improve the aesthetics of the magnetic connection device 100, the first fixing member 150 has a recess on the side opposite to the receiving member 142, and the through hole can be provided in the recess. The through hole can be a countersunk hole to prevent the screw head from protruding. In addition, a protective layer can be provided in the recess, which can completely cover the recess, thereby hiding the screw, through hole, and other structures, improving the overall neatness and aesthetics.

[0070] Similarly, a protective layer can also be provided on the side of the first magnetic component 110 facing away from the second opening 133 to further enhance its visual neatness. The material of the protective layer can be a soft material including but not limited to plastic or rubber. This not only protects the first magnetic component 110 from external damage, but also reduces wear and noise caused by direct contact between metal parts to a certain extent, effectively avoiding the reduction of aesthetics due to scratches on electronic devices.

[0071] A second aspect of this utility model also provides a magnetic bracket, which includes the magnetic connection device 100 described in any of the above embodiments and an adapter. The adapter is capable of connecting the magnetic connection device 100 and is suitable for connecting to external devices, thereby allowing electronic devices installed on the magnetic connection device 100 to flexibly adjust their angle and position to meet the needs of different usage scenarios. The adapter can be an adjustable support arm, a foldable bracket structure, or a support structure, etc. In other words, the adapter can take various forms, including but not limited to vehicle mounts, desktop stands, wall mounts, clamp structures, portable brackets, etc., to adapt to different installation environments and user needs. It should be noted that external devices include, but are not limited to, desktops, walls, and other supporting structures.

[0072] Given the improvements to the magnetic connection device 100, the magnetic bracket in this utility model has the technical effects of the magnetic connection device 100 in any of the above embodiments, which will not be elaborated here.

[0073] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0074] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0075] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
