Description

Technical Field

[0001] This utility model relates to the field of magnetic bracket technology, and in particular to a magnetic connection device and electronic device bracket that can effortlessly remove magnetically attached devices. Background Technology

[0002] Magnetic mounts are widely used due to their ease of fixing and adjusting, especially in desktop environments, in-car environments, and for attaching selfie sticks. Existing magnetic mounts primarily rely on built-in magnets to generate magnetic force, achieving the attraction and fixation of target objects. Based on this principle, magnetic mounts can be used to fix any type of magnetically attachable device, such as mobile phones and tablets.

[0003] Without altering the maximum magnetic force of the magnetic holder, to make it easier for users to detach magnetically attached devices from the holder, related technologies employ a method of driving the magnets within the holder to move. This adjusts the magnetic force by changing the relative position or angle between the magnets and the attracted object. However, adjusting the magnetic force by moving the magnets within the holder requires manual control by the user, making the process rather cumbersome. Utility Model Content

[0004] The main purpose of this invention is to provide a magnetic connection device and electronic device bracket that can remove magnetically attached devices with minimal effort, and to facilitate the switching of magnetic force.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] A magnetic connection device that allows for easy removal of magnetically attached devices includes:

[0007] The housing has a cavity and a support surface suitable for carrying magnetically attached devices;

[0008] A magnetic component, located in the cavity, is suitable for magnetically attracting magnetically supported devices that are carried on the support surface;

[0009] A lifting member is located in the cavity and is movably connected to the housing. The lifting member is configured to switch positions relative to the housing between a first position and a second position.

[0010] The first elastic element is located in the cavity and is connected to the lifting element. The first elastic element is configured to be locked in an elastic deformation state to store the first elastic force. After the first elastic force is released, it can drive the lifting element to move from the first position to the second position.

[0011] The lifting member includes a lifting end. When the lifting member is in the first position, the lifting end is located on the side of the bearing surface away from the magnetically attachable device. When the lifting member is in the second position, the lifting end is located on the side of the bearing surface facing the magnetically attachable device. During the process of the lifting member moving from the first position to the second position, the lifting end is adapted to push the magnetically attachable device supported on the bearing surface at least partially away from the bearing surface.

[0012] In some embodiments, one end of the first elastic member is connected to the housing and the other end is connected to the lifting member, which is configured to apply a first elastic force to the first elastic member during the process of moving from the second position to the first position.

[0013] In some embodiments, the lifting member includes a lifting portion and a rotating portion that are threadedly connected to each other. The lifting portion includes a lifting end and is slidably connected to the housing. The rotating portion is fixedly connected to the first elastic member and rotatably connected to the housing. During the process of the lifting member moving from the second position to the first position, the rotating portion rotates circumferentially, and the rotation axis is perpendicular to the bearing surface, thereby driving the lifting portion to slide in a direction parallel to the rotation axis.

[0014] In some embodiments, the magnetic connection device further includes a locking member, the lifting member includes a locking structure, the locking member has a third position and a fourth position, when the locking member is in the third position, the locking structure abuts against the locking member on one side of the circumferential direction to restrict the locking member from moving from the first position to the second position, and the first elastic member is locked in an elastic deformation state, when the locking member is in the fourth position, the locking member is spaced from the lifting member so that the first elastic force can be released.

[0015] In some embodiments, the locking structure includes a plurality of locking grooves arranged circumferentially at intervals. One side wall of the locking groove along the circumferential direction is a first groove wall, and the opposite side wall of the locking groove along the circumferential direction is a second groove wall. When the locking member is in the third position, the first groove wall abuts against the locking member. During the process of the lifting member moving from the second position to the first position, the rotating part rotates circumferentially relative to the locking member so that the locking member slides sequentially on the second groove wall of the plurality of locking grooves.

[0016] In some embodiments, the housing has an operating perforation communicating with the cavity and the outside. The locking member includes a locking part and an operating part connected to each other. The operating part passes through the operating perforation and extends out of the housing. The operating part extending out of the housing is configured to receive driving force and extend into the cavity through the operating perforation, and drive the locking part to move the locking member from a third position to a fourth position.

[0017] In some embodiments, the locking member further includes a second elastic member and a third elastic member. One end of the second elastic member is connected to the housing and the other end is connected to the operating part. One end of the third elastic member is connected to the housing and the other end is connected to the locking part. After the operating part extending out of the housing is configured to receive driving force, the second elastic member stores a second elastic force and the third elastic member stores a third elastic force. After the operating part loses driving force, both the second elastic force and the third elastic force are released, so that the locking member moves from the fourth position to the third position.

[0018] In some embodiments, the lifting member further includes a support plate located in the cavity along a direction parallel to the rotation axis. One end of the first elastic member is fixedly connected to the rotating part, and the other end passes through the support plate and is fixedly connected to the housing. During the process of the lifting member moving from the second position to the first position, the rotating part applies a first elastic force to the first elastic member.

[0019] In some embodiments, one end of the housing has a first end wall, and the bearing surface is the first end wall;

[0020] And / or,

[0021] The magnetic component is connected to the housing and has a second end wall. When the lifting component is in the first position, the second end wall and the first end wall are adapted to jointly support the magnetically attracted device.

[0022] And / or,

[0023] The housing has a first end wall on one side and the bearing surface is the first end wall. The lifting end has a third end wall. When the lifting member is in the first position, the first end wall and the third end wall are coplanar. The third end wall and the first end wall are suitable for jointly bearing the magnetically attracted device.

[0024] A second aspect of this utility model also provides an electronic device bracket, including the magnetic connection device of any of the above embodiments.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In this invention, after the movable lifting member is provided, when the lifting member is in the first position, its lifting end is located on the side of the bearing surface away from the magnetically pleasing device. This means that the lifting member does not lift the magnetically pleasing device at this time, and the magnetically pleasing device and the housing maintain a stable assembly state. When the lifting member switches to the second position, the lifting end moves to the side of the bearing surface facing the magnetically pleasing device, and pushes the magnetically pleasing device at least partially away from the bearing surface, making it convenient for the user to retrieve. Compared with the design of related technologies that requires the user to manually control the movement of the magnets in the magnetic bracket, in this invention, when the user needs to reduce the magnetic force to remove the magnetically pleasing device, the lifting member in the first position can automatically move to the second position through the elastic force of the first elastic member, thereby eliminating the corresponding operation and making the magnetic force switching operation more convenient. Therefore, the magnetic connection device of this invention can conveniently realize the magnetic force switching operation. Attached Figure Description

[0043] 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

[0044] 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.

[0045] 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.

[0046] 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.

[0047] Without altering the maximum magnetic force of the magnetic holder, to make it easier for users to detach magnetically attached devices from the holder, related technologies employ a method of driving the magnets within the holder to move. This adjusts the magnetic force by changing the relative position or angle between the magnets and the attracted object. However, adjusting the magnetic force by moving the magnets within the holder requires manual control by the user, making the process rather cumbersome.

[0048] In view of this, see Figures 1-7 This utility model provides a magnetic connection device 100 for effortless removal of magnetically attached devices. This magnetic connection device 100 can be used to magnetically fix any type of magnetically attached device. The magnetically attached device itself may be magnetic, or it may be magnetically fixed by assembling magnetic accessories. Specifically, the magnetically attached device may be a mobile phone or a tablet computer. The magnetic connection device 100 can fix the magnetically attached device solely by magnetic force, or it can work in conjunction with other forces (such as supporting force, clamping force, etc.) to fix the magnetically attached device. Depending on the actual application scenario, the magnetic connection device 100 can be fixed in different ways. For example, in a desktop environment, the magnetic connection device 100 can be placed directly on the table; in a vehicle environment, the magnetic connection device 100 can be fixed to the vehicle through its own clamping mechanism or magnetic attraction mechanism; additionally, the magnetic connection device 100 can also be held directly or indirectly by the user. In this case, the magnetic connection device 100 can be an accessory connecting to the back of a mobile phone, or used for fixing a selfie stick to a mobile phone. Furthermore, unless otherwise specified, the relative orientational reference relationship between the magnetic connection device 100 (including any part) and the magnetically attracted device described in this utility model refers to the positional relationship under a specific posture after the magnetic connection device 100 magnetically attracts and fixes the magnetically attracted device.

[0049] For details, see Figures 1-4 The magnetic connection device 100 includes a housing 110, a magnetic component 120, a lifting component 130, and a first elastic component 140. The housing 110 has a cavity 111 and a bearing surface 112 adapted to support a magnetically attractable device. The cavity 111 is the inner cavity of the housing 110 itself. The magnetic component is located in the cavity 111, and the magnetic component 120 is adapted to magnetically attract a magnetically attractable device supported on the bearing surface 112, thereby providing a magnetic force to attract the magnetically attractable device.

[0050] It is understood that the magnetic element 120 can be an embedded magnet or a surface-exposed magnet, with the bearing surface 112 of the housing 110 itself configured to be magnetic, serving as the magnetic element 120. It is also understood that in some embodiments, the magnetic element 120 plays an auxiliary role in fixing the magnetically attachable device to the magnetic connection device 100; that is, other structures are used to fix the magnetically attachable device to the magnetic connection device 100, and the adsorption effect of the magnetic element 120 is used in conjunction with other fixing structures to securely fix the magnetically attachable device to the magnetic connection device 100.

[0051] See Figures 1-4 The lifting member 130 is located in the cavity 111 and movably connected to the housing 110. The lifting member 130 is configured to switch positions relative to the housing 110 between a first position and a second position. It should be noted that the configuration described in this utility model, located in the cavity 111, can be entirely or partially located in the cavity 111.

[0052] See Figures 1-4 The first elastic element 140 is located in the cavity 111 and is connected to the lifting element 130. The first elastic element 140 is configured to lock in an elastic deformation state to store a first elastic force. After the first elastic force is released, it can drive the lifting element 130 to move from a first position to a second position. The lifting element 130 includes a lifting end 131. When the lifting element 130 is in the first position, the lifting end 131 is located on the side of the bearing surface 112 away from the magnetically attachable device (at this time, the lifting end 131 can be flush with the bearing surface 112 or it can be spaced from the bearing surface 112 to form a concave structure). When the lifting element 130 is in the second position, the lifting end 131 is located on the side of the bearing surface 112 facing the magnetically attachable device. During the process of the lifting element 130 moving from the first position to the second position, the lifting end 131 is adapted to push the magnetically attachable device supported on the bearing surface 112 at least partially away from the bearing surface 112.

[0053] See Figure 3When the lifting member 130 is in the first position, its lifting end 131 is located on the side of the bearing surface 112 away from the magnetically attachable device. This means that the lifting member 130 does not lift the magnetically attachable device at this time, and the magnetically attachable device and the housing 110 maintain a stable assembly state; see also Figure 4 When the lifting member 130 switches to the second position, the lifting end 131 moves to the side of the bearing surface 112 facing the magnetically attachable device, and pushes the magnetically attachable device at least partially away from the bearing surface 112 for easy access by the user. A driving member connected to the lifting member 130 provides power to move the lifting member 130 along a specific direction, achieving position switching. This process not only simplifies the separation operation of the magnetically attachable device and the magnetic connection device 100, but also improves the user experience. Specifically, since the bearing surface 112 includes a magnetic element, when the magnetically attachable device is fixed to the magnetic connection device 100, it will be magnetically attracted to the magnetic connection device 100 by the magnetic element 120. The lifting member 130, by lifting the magnetically attachable device along the first direction, weakens the attraction of the magnetic element 120 to the magnetically attachable device, thus reducing the binding force of the magnetic connection device 100 on the magnetically attachable device, making it easier to remove the magnetically attachable device.

[0054] Regarding the bearing surface 112, it can be understood that the bearing surface 112 is a general term for the surface that supports the magnetically attachable device after it is fixed to the magnetic connection device 100. Specifically, the bearing surface 112 can be the outer shell of the housing 110, the end face of the magnetic component 120 or the lifting component 130, or any combination of the above structures configured as the bearing surface 112. When the lifting component 130 is in the first position, the upper end face of the lifting component 130 can be separated from the magnetically attachable device, that is, at this time the bearing surface 112 includes the surface of the housing 110. In the first position, the upper end face of the lifting component 130 can also contact the magnetically attachable device, at which time the bearing surface 112 includes the surface of the housing 110 and the surface of the lifting component 130. When the lifting member 130 is in the second position, the magnetic device is lifted by the lifting member 130, and at least part of the outer wall of the magnetic device that was originally attached to the upper surface of the housing 110 is separated from the upper surface of the housing 110. As a result, the housing 110’s control over the magnetic device is weakened, making it easier for the user to take away the magnetic device.

[0055] It is understandable that the effect of the lifting member 130 on the magnetically oriented device in the second position can vary. For example, in the second position, the lifting member 130 completely lifts the magnetically oriented device, meaning that at this point, the outer wall of the magnetically oriented device and the outer wall of the housing 110 have no contact area, and the magnetically oriented device and the outer wall of the housing 110 are completely separated. In some embodiments, the lifting member 130 in the second position can also be configured to partially lift the magnetically oriented device. This can be understood as the magnetically oriented device tilting towards the housing 110 under the action of the lifting member 130, reducing the contact area between the two compared to the original contact area, decreasing the housing 110's control over the magnetically oriented device, and facilitating the removal of the magnetically oriented device.

[0056] Of course, in some embodiments, the lifting member 130 acts on the central region of the magnetically attached device. This design makes the magnetically attached device less susceptible to damage when acted upon by the lifting member 130. In some embodiments, the lifting member 130 acts on the edge of the magnetically attached device. This design can also achieve the effect of lifting the magnetically attached device away from the bearing surface 112. Here, lifting away refers to reducing the binding force of the magnetic connection device 100 on the magnetically attached device, not necessarily completely separating it. Furthermore, when the lifting member 130 acts on the edge of the magnetically attached device, it only needs to provide a small force to tilt the magnetically attached device and separate it from the bearing surface 112.

[0057] In some embodiments, the lifting member 130 can also push the magnetically attached device away from the side. For example, the magnetically attached device is attached to the bearing surface 112 in the vertical direction. Through the linkage structure, the lifting member 130 pushes the magnetically attached device away in the horizontal direction, thereby reducing the contact area between the magnetically attached device and the bearing surface 112 and weakening the binding ability of the magnetic member 120 on the magnetically attached device.

[0058] In some embodiments, to enhance the friction between the bearing surface 112 and the magnetically attachable device and prevent the device from sliding, a special texture treatment can be applied to the surface of the bearing surface 112, such as adding fine frosted textures or anti-slip particles. Simultaneously, to protect the housing of the magnetically attachable device from scratches, a soft protective pad, such as a silicone pad or a velvet pad, can be attached to the area where the bearing surface 112 contacts the device, providing both cushioning and improved user experience. Since the end of the lifting member 130 also contacts the magnetically attachable device, in some embodiments, a silicone top cover is provided at the end of the lifting member 130 to protect the magnetically attachable device. The top cover can be attached to the end of the lifting member 130 by sleeve or by fitting.

[0059] As can be seen, in the present invention, after the movable lifting member 130 is provided, when the lifting member 130 is in the first position, its lifting end 131 is located on the side of the bearing surface 112 away from the magnetically pleasing device. This means that the lifting member 130 does not lift the magnetically pleasing device at this time, and the magnetically pleasing device and the housing 110 maintain a stable assembly state. When the lifting member 130 switches to the second position, the lifting end 131 moves to the side of the bearing surface 112 facing the magnetically pleasing device and pushes the magnetically pleasing device at least partially away from the bearing surface 112, making it convenient for the user to take it. Compared with the design in related technologies that requires the user to manually control the movement of the magnets in the magnetic bracket, in the present invention, when the user needs to reduce the magnetic force to take away the magnetically pleasing device, the lifting member 130 in the first position can automatically move to the second position through the elastic force of the first elastic member 140, thereby eliminating the corresponding operation and making the operation of switching the magnetic force more convenient. Therefore, the magnetic connection device 100 of this utility model can conveniently realize the operation of switching magnetic attraction force.

[0060] For the method by which the first elastic element 140 obtains the first elastic force, see [link to relevant documentation]. Figures 3-4 In some embodiments, the first elastic member 140 is connected at one end to the housing 110 and at the other end to the lifting member 130. The lifting member 130 is configured to apply a first elastic force to the first elastic member 140 during the movement from the second position to the first position. With the above configuration, the lifting member 130 can apply an elastic force to the first elastic member 140 during position switching, and when the first elastic member 140 is locked in its elastic deformation state, the lifting member 130 can also be locked in the first position. For the specific operation of the first elastic member 140, please refer to the following text.

[0061] For the specific settings of the lifting component 130, please refer to [link / reference]. Figures 1-4In some embodiments, the lifting member 130 includes a lifting portion 132 and a rotating portion 133 threadedly connected to each other. The lifting portion 132 includes a lifting end 131 and is slidably connected to the housing 110. The rotating portion 133 is fixedly connected to the first elastic member 140 and rotatably connected to the housing 110. During the process of the lifting member 130 moving from the second position to the first position, the rotating portion 133 rotates in the circumferential direction R, and the axis of rotation is perpendicular to the bearing surface 112, thereby driving the lifting portion 132 to slide in a direction parallel to the axis of rotation. For ease of explanation, the direction perpendicular to the bearing surface 112 (i.e., the direction parallel to the axis of rotation) is referred to as the first direction. It is understandable that during the switching process between the first position and the second position of the lifting member 130, the rotating part 133 rotates in place and the overall position remains unchanged. Since the lifting part 132 and the rotating part 133 form a threaded fit, and the lifting part 132 and the housing 110 are slidably connected in the first direction, the lifting part 132 can reciprocate in the first direction while the rotating part 133 rotates in the forward and reverse directions, thereby realizing the switching between the first position and the second position.

[0062] To make the position of the lifting component 130 more stable, see Figures 3-7 In some embodiments, the magnetic connection device 100 further includes a locking member 150, and the lifting member 130 includes a locking structure 134. The locking member 150 has a third position and a fourth position. When the locking member 150 is in the third position, the locking structure 134 abuts against the locking member 150 on one side along the circumferential direction R to restrict the locking member 150 from moving from the first position to the second position, and the first elastic member 140 is locked in an elastic deformation state. When the locking member 150 is in the fourth position, the locking member 150 is spaced apart from the lifting member 130 so that the first elastic force can be released. It is understood that when the locking member 150 is in the third position, it can prevent the rotation of the rotating part 133, thereby preventing the first elastic member 140 from releasing the elastic force, so that the lifting member 130 is locked in the first position. When the locking member 150 is in the fourth position, it no longer plays the above-mentioned obstructive role, and then the first elastic member 140 can drive the lifting member 130 to move from the first position to the second position.

[0063] For the specific mating configuration of locking element 150 and locking structure 134, please refer to... Figures 3-6In some embodiments, the locking structure 134 includes a plurality of locking grooves 1341 spaced apart along the circumferential direction R. One side wall of the locking groove 1341 along the circumferential direction R is a first groove wall 13411, and the opposite side wall along the circumferential direction R is a second groove wall 13412. When the locking member 150 is in the third position, the first groove wall 13411 abuts against the locking member 150. During the process of the lifting member 130 moving from the second position to the first position, the rotating part 133 rotates relative to the locking member 150 along the circumferential direction R, so that the locking member 150 slides sequentially on the second groove wall 13412 of the plurality of locking grooves 1341. During the switching between the first position and the second position, the locking member 150 can sequentially engage with two adjacent locking grooves 1341 along the circumferential direction R. To achieve precise engagement, the interval angle between the plurality of locking grooves 1341 that sequentially engage with the locking member 150 can correspond to the angle rotated by the rotating part 133 after the first elastic force is released. According to the requirements, the magnitude of the first elastic force released by the first elastic member 140 can be set to be adjustable. Correspondingly, the distance between the locking member 150 and the third position and the fourth position can be set to be adjustable, so as to adjust the distance by which the lifting member 130 is lifted, so as to adjust the magnitude of the magnetic attraction force after it is reduced.

[0064] To control the locking element 150, see [link / reference]. Figures 3-4 In some embodiments, the housing 110 has an operating through-hole 113 communicating the cavity 111 with the outside. The locking member 150 includes a locking part 151 and an operating part 152 connected to each other. The operating part 152 passes through the operating through-hole 113 and extends out of the housing 110. The operating part 152 extending out of the housing 110 is configured to, after receiving driving force, extend into the cavity 111 through the operating through-hole 113 and drive the locking part 151, so that the locking member 150 moves from a third position to a fourth position. The operating part 152 can drive the locking part 151 in any manner. For example, in some embodiments, the operating part 152 and the locking part 151 can be directly connected, in which case the operating part 152 and the locking part 151 move synchronously and in the same direction; see also Figures 3-7 In other embodiments, the operating unit 152 drives the locking unit 151 via a linkage transmission, such as a linkage drive, gear drive, or rack and pinion drive. More specifically, in Figures 3-7In the embodiment shown, the movement direction of the operating part 152 (i.e., the extension direction of the operating through hole 113) is perpendicular to the rotation axis. The locking part 151 has a first through hole and a second through hole, both of which extend along a first direction. The locking member 150 is provided with a first shaft, which passes through the first through hole to form a rotatable connection between the operating part 152 and the locking part 151. The housing 110 or a component fixedly connected to the housing 110 (specifically, the support plate 135 described later) is provided with a second shaft, which passes through the second through hole to form a rotatable connection between the locking part 151 and the housing 110. After the above two connections are formed, while the operating part 152 moves in a direction perpendicular to the rotation axis, it can drive the locking part 151 to rotate in a direction around the second shaft, so that the locking member 150 moves from the third position to the fourth position.

[0065] To ensure that the locking element 150 automatically resets after being unlocked by the user (i.e., after the locking element 150 moves from the third position to the fourth position), see [link to relevant documentation]. Figures 3-7 In some embodiments, the locking member 150 further includes a second elastic member 153 and a third elastic member 154. One end of the second elastic member 153 is connected to the housing 110 and the other end is connected to the operating part 152. One end of the third elastic member 154 is connected to the housing 110 and the other end is connected to the locking part 151. When the operating part 152, which extends out of the housing 110, is configured to receive driving force, the second elastic member 153 stores a second elastic force, and the third elastic member 154 stores a third elastic force. When the operating part 152 loses driving force, both the second and third elastic forces are released, causing the locking member 150 to move from the fourth position to the third position. After the aforementioned elastic forces are released, the locking member 150 returns to its state when it is not subject to driving force, making the user's operation more convenient. More specifically, the above-mentioned elastic element can be applied to the embodiment described in the foregoing embodiment that has a first shaft and a second shaft. In this case, the second elastic element 153 is sleeved on the outer side of the end of the operating part 152 near the rotating part 133, and the extension direction is the same as the direction of the driving force. The third elastic element 154 is sleeved on the outer side of the second shaft.

[0066] Regarding the position switching method of the locking element 150, in some other embodiments, the position switching of the locking element 150 can be controlled by any other suitable structure, or it can also be controlled by an electric drive.

[0067] See Figures 3-7In some embodiments, the lifting member 130 further includes a support plate 135 located in the cavity 111. Along a direction parallel to the rotation axis, one end of a first elastic member 140 is fixedly connected to the rotating part 133, and the other end passes through the support plate 135 and is fixedly connected to the housing 110. During the process of the lifting member 130 moving from the second position to the first position, the rotating part 133 applies a first elastic force to the first elastic member 140. It is understood that the support plate 135 is disposed between the rotating part 133 and the first elastic member 140. Since the first elastic member 140 passes through the support plate 135 (specifically, it may pass through a through hole in the middle of the support plate 135), the support plate 135, while supporting and rotatably connecting the rotating part 133, will not move together with the rotating part 133 and the first elastic member 140. To further utilize the structure of the support plate 135, a mounting groove can be provided on the side of the support plate 135 near the locking member 150 along the first direction. The operating member is at least partially located in the mounting groove. The operating member can move within the mounting groove in a direction perpendicular to the rotation axis (at this time, the mounting groove can serve as a guide for the movement of the operating member). In addition, the third elastic member 154 and the second shaft described in the aforementioned embodiment can be fixedly connected to the support plate 135.

[0068] Regarding the form of the bearing surface 112 in different embodiments, firstly, in some embodiments, the housing 110 has a first end wall 114, and the bearing surface 112 includes the first end wall 114. In this case, when the lifting member 130 is in the first position, the magnetically attached device can be supported solely by the first end wall 114. In other words, the magnetic member 120 is not exposed, and only the exposed surface of the housing 110, i.e., the first end wall 114, is used to support the magnetic connection device 100.

[0069] In other embodiments, the housing 110 has a first end wall 114, and the bearing surface 112 includes the first end wall 114. A magnetic element 120 is connected to the housing 110, and the magnetic element 120 has a second end wall 121. In this case, when the lifting member 130 is in the first position, it can rely on the first end wall 114 and the second end wall 121 to jointly support the magnetically attracted device. This embodiment can be understood as the surface of the magnetic element 120 being exposed, and the magnetic connection device 100 being supported only by the exposed surface of the magnetic element 120, i.e., the bearing surface 112 includes the second end wall 121.

[0070] In some embodiments, the housing 110 has a first end wall 114, and the bearing surface 112 includes the first end wall 114. The lifting end 131 is provided with a third end wall 136. When the lifting member 130 is in the first position, the magnetically oriented device can be supported by the first end wall 114 and the third end wall 136 (the second end wall 121 can also provide support at this time). In summary, the wall surface supporting the magnetically oriented device can be derived from any one of the structures of the magnetic member 120, the housing 110, and the lifting end 131, or any combination of two or three structures.

[0071] For ease of understanding, the following describes the specific usage process of the magnetic connection device 100 in one embodiment. Initially, the lifting member 130 is in the second position, at which point the magnetic connection device 100 does not support the magnetically attachable device. When it is necessary to magnetically attach the magnetically attachable device, the user places the magnetically attachable device on the upper end of the lifting member 130 protruding from the housing 110. Under the influence of gravity (and simultaneously the magnetic attraction force of the magnetic member 120), the magnetically attachable device presses down on the lifting member 130. The lifting portion 132 of the lifting member 130 moves vertically downward relative to the housing 110, thus lifting... The rotating part 133 of component 130 rotates along the circumferential direction R under the action of the threaded connection (at this time, the axis of rotation is parallel to the first direction). The rotation of the rotating part 133 causes the locking part 150 to slide in one of the locking grooves 1341 of the rotating part. After the locking part 150 disengages from the locking groove 1341, it continues to move until the lifting part 130 moves to the limit position (i.e., the first position). At this time, the movement limit of the lifting part 130 can be formed by the limiting structure of the housing 110 and the lifting part 130, or by the threaded structure of both the rotating part 133 and the lifting part 132. After the lifting part 130 moves to the limit position, it is located in the first position, and the locking part 150 just engages with the other locking groove 1341 of the rotating part. At this time, the groove surface of the locking groove 1341 abuts against the locking part 150, thereby restricting the reverse rotation of the rotating part 133 (i.e., the reverse rotation along the circumferential direction R). During the above movement process, the first elastic element 140 rotates with the rotating part 133, is subjected to torsional force, and stores the first elastic force. At this point, the magnetic attraction is complete, and the magnetic force is maximized. To reduce the magnetic force, the first elastic force needs to be released, causing the lifting member 130 to automatically move from the first position to the second position. To achieve this, the user can push the exposed rod-shaped operating part 152 inward in the horizontal direction. Under the action of the rotational connection between the first and second shafts, the operating part 152 drives the locking part 151 to rotate, causing the locking part 151 to disengage from the locking groove 1341. Consequently, the rotating part 133 is no longer restricted in its rotation, the first elastic force is released, and the rotating part 133 is driven to rotate in the opposite direction of the circumferential direction R. Due to the threaded connection, the lifting part 132 moves vertically upward relative to the housing 110. After the lifting member 130 moves to its limit position, it is located in the second position, with the lifting end 131 completely protruding from the housing 110. At this point, the operation of reducing the magnetic force is completed, the magnetic force is 0, and the magnetic connection device 100 is supported only by the lifting member 130, allowing the user to easily remove the magnetic connection device 100.

[0072] A second aspect of this utility model also provides an electronic device holder, which includes the magnetic connection device 100 of any of the above embodiments. Besides supporting the electronic device, the electronic device holder can also have other functions. Therefore, taking a mobile phone as an example, the electronic device holder can specifically be a mobile phone mounting bracket (for fixing on a desktop, vehicle, or any suitable scenario), a bracket accessory connecting to the back of the mobile phone, a magnetic power bank, a magnetic wireless charger, or a selfie stick. The magnetically attachable device includes any type of electronic device.

[0073] In some embodiments, the magnetic connection device 100 serves as the entirety of the electronic device bracket; in other embodiments, the electronic device bracket includes multiple components, and the magnetic connection device 100 may be one of these components. The multiple components may be mechanically connected to each other or spaced apart from each other. For example, when the magnetically attached device is a mobile phone and the electronic device bracket is a magnetic wireless charger, the magnetic connection device 100 serves as a module for fixing and supporting the mobile phone. The electronic device bracket also includes a charging module, which is electrically connected to the magnetic connection device 100, so that the electronic device bracket can supply power to the mobile phone while supporting it.
