[0040] 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

[0041] 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.

[0042] In view of this, please refer to Figures 1 to 7This utility model provides a magnetic support device 100, which includes a housing assembly 110 and a magnetic assembly 120. The housing assembly 110 has a receiving cavity 111. The housing assembly 110 has a first mounting surface 112 and a second mounting surface 113 on opposite sides in a first direction X. The first direction X can be parallel to the direction from the first device 200 to the second device 300, i.e., the direction perpendicular to the first mounting surface 112. The first mounting surface 112 is used to contact and support the first device 200, including but not limited to a tablet computer, smartphone, desktop, or other fixed surface; the second mounting surface 113 is used to contact and support the second device 300, including but not limited to a tablet computer, smartphone, desktop, or other fixed surface. It should be noted that when the first mounting surface 112 is used to contact and support electronic devices such as mobile phones, the second mounting surface 113 is used to contact and support desktops or other fixed surfaces; when the first mounting surface 112 is used to contact and support desktops or other fixed surfaces, the second mounting surface 113 is used to contact and support electronic devices such as mobile phones, so that mobile phones and other electronic devices can be fixed to desktops or other fixed surfaces by the magnetic support device 100, ensuring that the devices are stable and do not easily slip. For ease of description, the following description of the structure and principle of the magnetic support device 100 takes the first mounting surface 112 being used to contact and support a mobile phone as an example.

[0043] The direction perpendicular to the first direction X is defined as the second direction Y. The magnetic suction assembly 120 is disposed within the receiving cavity 111. This magnetic suction assembly 120 is suitable for providing an attractive force to the first device 200 and / or the second device 300, so that the first device 200 can be firmly attached to the second device 300 via the magnetic suction assembly 120, ensuring a tight fit and preventing separation to avoid damage from falling. The magnetic suction assembly 120 includes a first magnetic element 121 and a second magnetic element 122, which are arranged opposite to each other along the second direction Y. The first magnetic element 121 can move relative to the first mounting surface 112 along the first direction X, thereby facilitating changes in the distance between the first magnetic element 121 and the first mounting surface 112. This allows the attractive force of the magnetic support device 100 on the first device 200 to be gradually eliminated, facilitating the effortless removal of the first device 200.

[0044] Specifically, when the first device 200 is mounted on the first mounting surface 112 and the second device 300 is mounted on the second mounting surface 113, the first magnetic member 121 and the second magnetic member 122 together provide a sufficiently large attraction force to the first device 200, ensuring the installation stability of the first device 200. When it is necessary to remove the first device 200, simply pull the first device 200 along the first direction X. The first magnetic member 121 then provides an attraction force to the first device 200 and moves along the first direction X with the first device 200, that is, the first magnetic member 121 moves relative to the first mounting surface 112 under the action of this pulling force. Simultaneously, the distance between the second magnetic member 122 and the first device 200 gradually increases, and its attraction force to the first device 200 gradually weakens. At this point, by continuously applying a slight pulling force to the first device 200, the first device 200 can overcome the attraction force of the first magnetic member 121 and slowly detach from the first mounting surface 112, ultimately achieving easy removal.

[0045] In other words, the process of removing the first device 200 from the first mounting surface 112 has two stages. First, as the first magnetic member 121 moves with the first device 200, the user only needs to apply a pulling force to the first device 200 that is strong enough to overcome the attraction force of the second magnetic member 122 to detach the first device 200 from the magnetic member 122's attraction. Second, after the first device 200 is detached from the attraction of the second magnetic member 122, continuously applying a slight pulling force to the first device 200 will detach it from the attraction of the first magnetic member 121, ultimately achieving easy removal.

[0046] In some embodiments, the second magnetic member 122 is also configured to move relative to the first mounting surface 112, but the range of movement of the second magnetic member 122 along the first direction X is smaller than the range of movement of the first magnetic member 121, so that the magnetic support device 100 has a certain anti-vibration performance during use. In other words, the range of movement of the second magnetic member 122 provides a buffer space for the first device 200, effectively preventing it from accidentally falling off due to vibration.

[0047] Compared to related technologies that rely on a single magnetic element to provide adsorption force, this application employs a design where the first magnetic element 121 and the second magnetic element 122 work synergistically, significantly improving the stability and controllability of the adsorption force. Furthermore, the design allowing the first magnetic element 121 to move relative to the first mounting surface 112 along the first direction X ensures efficient and convenient installation and removal of the first device 200, effectively preventing accidental drops and improving the ease of removal. Moreover, compared to the fixed adsorption method in related technologies, this application further optimizes the removal process of the first device 200 by gradually eliminating the adsorption force through the movement of the first magnetic element 121 relative to the first mounting surface 112, reducing operational difficulty and improving user experience. Additionally, the arrangement of the first magnetic element 121 and the second magnetic element 122 relative to each other along the second direction Y ensures a more uniform distribution of magnetic force during installation and removal of the first device 200, and the independent operation of the first magnetic element 121 and the second magnetic element 122 avoids mutual interference. It should be noted that the applicant initially considered setting the two magnetic components coaxially and nested together. However, the applicant found that nested magnetic components were prone to magnetic interference, affecting the adsorption effect. Moreover, setting a large distance between the two magnetic components would result in a larger device size. In this application, the arrangement of the first magnetic component 121 and the second magnetic component 122 opposite each other results in a greater distance between them, effectively reducing magnetic interference, reducing the device size, and improving the overall compactness and practicality of the structure.

[0048] Please see Figure 3To further improve the uniformity of the adsorption force of the magnetic component 120 and ensure the adsorption effect, in some embodiments, both the first magnetic component 121 and the second magnetic component 122 are designed as semi-circular arc structures. For ease of description, the first magnetic component 121 is configured as a first semi-circular ring, and the second magnetic component 122 is configured as a second semi-circular ring. The opening directions of the first semi-circular arc are opposite to and opposite to the opening directions of the second semi-circular arc, so that the first and second semi-circular arcs can together form a complete circular magnetic structure, thereby achieving uniform force in all directions during the adsorption process and ensuring the stability and reliability of the adsorption. To further reduce the magnetic interference between the first magnetic component 121 and the second magnetic component 122, the inner diameter of the first semi-circular ring formed by the first magnetic component 121 is the same as the inner diameter of the second semi-circular ring formed by the second magnetic component 122. This also balances the lever arm length, preventing equipment tilting caused by excessive magnetic force on one side, maintaining a balanced distribution of adsorption force, further improving the stability and durability of the adsorption effect, and ensuring the safety and reliability of the first device 200 during long-term use. It is understood that the first magnetic component 121 and the second magnetic component 122 can be made of the same or different materials, including but not limited to high-performance magnetic materials such as neodymium iron boron and AlNiCo.

[0049] Please see Figure 3 Specifically, the housing assembly 110 includes a housing 114 and a bottom cover 115, which together define the receiving cavity 111. The magnetic suction assembly 120 can be located within the receiving cavity 111 on the side near the first mounting surface 112, i.e., the first mounting surface 112 is located on the side of the housing 114 opposite to the bottom cover 115. Thus, the housing 114 can attract the first device 200 under the action of the magnetic suction assembly 120. The housing 114 can be made of a material capable of conducting magnetic force, including but not limited to stainless steel, iron, and other metal materials. To further improve the adsorption effect, the first mounting surface 112 can be configured with a micro-concave adsorption area, so that the first device 200 has a tighter contact with the first mounting surface 112. The micro-concave design of the adsorption area not only increases the contact area but also helps to disperse pressure, thereby enhancing the stability of adsorption. In addition, to optimize the user experience, the bottom cover 115 can be designed to be detachable, allowing the user to replace the magnetic suction assembly 120 as needed, ensuring that the magnetic support device 100 has excellent adsorption capabilities.

[0050] In some embodiments, the bottom cover 115 is configured to directly adhere to the second device 300 under the action of the magnetic assembly 120, such as a desktop or other fixed surface. In other embodiments, the bottom cover 115 may also be equipped with connecting structures, such as screw holes, adhesive layers, or clamps, to facilitate fixing the bottom cover 115 to the second device 300 via these connecting structures. This increases the flexibility and convenience of using the magnetic support device 100. For surfaces unsuitable for magnetic fixation, such as wooden desktops or glass, stable support can be achieved through connecting structures.

[0051] In some embodiments, the bottom cover 115 is fixedly connected to the phone casing 114 via a connecting structure. That is, the first mounting surface 112 is located on the side of the casing 114 away from the bottom cover 115, while the second mounting surface 113 is located on the side of the bottom cover 115 away from the casing 114. In this case, the second mounting surface 113 contacts and supports the phone casing 114 via the connecting structure, so that the magnetic support device 100 can provide a stable support effect for electronic devices such as mobile phones while providing a certain degree of protection.

[0052] Please see Figure 3 and Figure 7 In some embodiments, the outer casing 114 includes a first casing 1141 and a second casing 1142, wherein the side wall of the first casing 1141 facing away from the bottom cover 115 serves as a first mounting surface 112 for contacting and supporting the first device 200. The side of the first casing 1141 facing away from the bottom cover 115 has a clearance hole 1141b communicating with the receiving cavity 111. For ease of understanding, the side wall of the second casing 1142 facing away from the bottom cover 115 is defined as having a third mounting surface 1142d. The second casing 1142 passes through the clearance hole 1141b and is movable relative to the first casing 1141 in a first direction X, thereby changing the distance between the third mounting surface 1142d and the first mounting surface 112. A first magnetic chuck 121 is disposed between the bottom cover 115 and the second casing 1142, while a second magnetic chuck 122 is located between the bottom cover 115 and the first casing 1141. Therefore, when the first device 200 is attracted to the housing 114, both the first mounting surface 112 and the third mounting surface 1142d can contact and provide support for the first device 200. During the removal of the first device 200, the third mounting surface 1142d moves with the first device 200 under the action of the first magnetic member 121, causing the third mounting surface 1142d to gradually move away from the first mounting surface 112, and the first device 200 detaches from the first mounting surface 112. As a pulling force is continuously applied to the first device 200 to keep it moving, the attraction force of the second magnetic member 122 is overcome, and the third mounting surface 1142d separates from the first device 200, thus achieving effortless removal of the first device 200.

[0053] Please see Figure 3 and Figure 7 In some embodiments, a retaining strip 1142a is provided around the periphery of the end of the second housing 1142 facing the bottom cover 115. The design of this retaining strip 1142a allows its side facing away from the bottom cover 115 to be separably contacted with the side of the first housing 1141 facing the bottom cover 115. The presence of the retaining strip 1142a not only helps to enhance the stability and guidance of the second housing 1142 during movement, but also reduces the risk of dust and other fine particles entering the receiving cavity 111, protecting the internal components from contamination. Furthermore, the material of the retaining strip 1142a can be selected as wear-resistant and scratch-resistant, including but not limited to polycarbonate or hard rubber, to extend the service life of the second housing 1142.

[0054] In some embodiments, a protrusion may be provided on the side of the baffle 1142a away from the bottom cover 115. The protrusion may be located on the baffle 1142a at the end away from the first mounting surface 112. Thus, when the second housing 1142 moves with the first device 200 along the first direction X, the protrusion will first abut against the side wall of the first housing 1141 facing the bottom cover 115. During the continuous movement of the first device 200, the third mounting surface 1142d will tilt away from the first mounting surface 112 under the action of the protrusion, which will further increase the distance between the first mounting surface 112 and the third mounting surface 1142d. The distance between the first device 200 and the first mounting surface 112 will further increase, and the attraction force of the second magnetic member 122 on the first device 200 will be further weakened, so that the first device 200 can be removed more easily. Meanwhile, the tilting effect of the third mounting surface 1142d also makes it easier for the first device 200 to detach from the magnetic attraction force of the first magnetic member 121, making the removal of the first device 200 easier and smoother. It should be noted that compared to applying a pulling force to the first device 200 in a direction parallel to the magnetic field lines to make it detach from the magnetic attraction force, applying a pulling force in a direction perpendicular to the magnetic field lines or tilted to the magnetic field lines can more effectively reduce the magnetic resistance, thereby achieving a more convenient removal of the first device 200.

[0055] Please see Figure 7In some embodiments, the first housing 1141 has a first groove 1141a on the side facing the bottom cover 115, while the second housing 1142 has a second groove 1142b on the side facing the bottom cover 115. The second magnetic member 122 is engaged in the first groove 1141a, ensuring its position is fixed and will not move arbitrarily; the first magnetic member 121 is engaged in the second groove 1142b, similarly ensuring its stability. This design not only allows for precise control of the position of the magnetic member but also effectively prevents displacement of the magnetic member due to accidental collisions or vibrations, thereby affecting the adsorption effect. In addition, the groove design helps to improve the overall integration and compactness of the magnetic assembly 120, making the device more stable and reliable. Furthermore, the shape and size of the second groove 1142b and the first groove 1141a can be designed to match the magnetic member to ensure that the magnetic member can be securely and tightly fixed within them. To further enhance the stability of the magnetic connector, an anti-slip material can be added to the inner wall of the groove or an embedded design can be adopted to create a tighter bond between the magnetic connector and the groove.

[0056] In some embodiments, since the first magnetic member 121 and the second magnetic member 122 are arranged opposite to each other and spaced apart along the second direction Y, the attraction between the first magnetic member 121 and the second magnetic member 122 will be canceled out to a certain extent. Therefore, a protruding baffle can be provided on the side of the first housing 1141 facing the bottom cover 115. This protruding baffle can be made of the same metal material as the first housing 1141, so that it has good magnetic conductivity. Thus, the adjacent sides of the second magnetic member 122 can respectively contact the side of the first housing 1141 facing the bottom cover 115 and the side of the protruding baffle along the second direction Y. This reduces the design and manufacturing difficulty of the first housing 1141 while enhancing the stability of the second magnetic member 122. At the same time, it makes the first housing 1141 more dimensionally compatible with the second magnetic member 122.

[0057] Please see Figure 3 In some embodiments, the housing assembly 110 further includes a mounting bracket 116 disposed within the receiving cavity 111. The mounting bracket 116 has a first mounting position 1161 and a second mounting position 1162 disposed opposite each other along the second direction Y. The first magnetic member 121 is detachably contacted with the first mounting position 1161 to facilitate movement of the first magnetic member 121 along the first direction X with the second housing 1142. The second magnetic member 122 abuts against the first housing 1141 and the second mounting position 1162 on opposite sides along the first direction X, respectively. That is, the second magnetic member 122 remains stable under the clamping of the first housing 1141 and the mounting bracket 116, ensuring that it will not be displaced by external forces during the use of the magnetic support device 100, thereby ensuring the reliability and safety of the entire device.

[0058] Please see Figure 3 and Figure 5 In some embodiments, the first mounting position 1161 is provided with a plurality of guide holes 1163, which are spaced apart along the periphery of the first magnetic member 121. The second housing 1142 facing the bottom cover 115 is provided with guide members 1142c corresponding to each guide hole 1163. The guide members 1142c are inserted into the guide holes 1163 and can slide along the first direction X, so that the second housing 1142 can move smoothly along the first direction X, while preventing the second housing 1142 from deviating or rotating abnormally during the movement.

[0059] Please see Figure 3 and Figure 6 In some embodiments, the housing assembly 110 further includes a reset member 117, one end of which is connected to the mounting bracket 116, and the other end is connected to the second housing 1142. The reset member 117 has elastic properties and can automatically return to its original position after the second housing 1142 is subjected to external force. Specifically, when the first device 200 separates from the third mounting surface 1142d, the reset member 117 generates a restoring force through elastic deformation, driving the second housing 1142 back to its initial position, ensuring the stability and reusability of the device. The reset member 117 may be made of a highly elastic material, including but not limited to spring steel, to provide a durable and stable restoring force. In some embodiments, the number of reset members 117 may be multiple to ensure sufficient restoring force, and the arrangement of multiple reset members 117 can make the force distribution on the housing uniform, improving the reset effect.

[0060] To facilitate the installation of the reset member 117, the first magnetic chuck 121, and the second magnetic chuck 122, in some embodiments, the mounting bracket 116 includes an arc-shaped structure and a straight plate structure. The arc-shaped structure is used to install the first magnetic chuck 121 and the second magnetic chuck 122. The two ends of the straight plate structure are respectively connected to the two ends of the arc-shaped structure, improving the rigidity and stability of the mounting bracket 116. Simultaneously, part of the structure of the second housing 1142 can also be effectively supported by the straight plate structure, ensuring the overall structural stability. Furthermore, the reset member 117 can also be connected to the mounting bracket 116 through this straight plate structure.

[0061] Please see Figure 6To improve the installation stability and service life of the reset component 117, in some embodiments, the reset component 117 adopts a spring-loaded structure, which includes a first connecting portion 1171 for connecting the second housing 1142, a second connecting portion 1172 for connecting the mounting bracket 116, and an elastic segment 1173 between the two. The planes containing the first connecting portion 1171 and the second connecting portion 1172 are parallel to each other and have a certain angle of inclination with the plane containing the elastic segment 1173, so that the elastic segment 1173 can generate a greater restoring force when compressed or stretched, thereby improving the reset effect. The side of the second connecting portion 1172 facing away from the bottom cover 115 contacts the side of the mounting bracket 116 facing the bottom cover 115, and the end of the elastic segment 1173 near the second connecting portion 1172 has a bent portion 1174, the protruding end of which can abut against the bottom cover 115 to enhance the fixing stability of the reset component 117. The bending portion 1174 not only provides the reset component 117 with sufficient restoring force to ensure the reset effect, but also plays a buffering role during the reset process, reducing the friction between the reset component 117 and the bottom cover 115 and extending the service life of the reset component 117.

[0062] 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.

[0063] 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.
