Description

Technical Field

[0001] This invention relates to the field of magnetic bracket technology, and in particular to a magnetic connection device and magnetic accessories that allow for effortless removal of magnetically attached devices. Background Technology

[0002] Existing magnetic stands all rely on the strong attraction between an internal magnet and the magnet inside the electronic device or its protective case to fix and support the device. However, to ensure a stable attraction, the magnetic force of the stands is generally too strong, requiring users to apply a large force perpendicular to the stand surface when removing the electronic device. This is inconvenient, easily causes hand fatigue, is not friendly to children and the elderly, and can easily damage the preset angle of the stand.

[0003] Furthermore, electronic devices from different manufacturers and of different sizes vary significantly in weight when protected with a case. However, manufacturers often design cases based on the ability to hold the heaviest electronic devices, resulting in fixed and excessively strong magnetic forces that cannot be adjusted according to the actual weight of the electronic devices and user habits, further exacerbating the difficulty of removing the devices. Summary of the Invention

[0004] The main objective of this invention is to provide a magnetic connection device and magnetic accessories that allow for easy and effortless removal of magnetically attached devices.

[0005] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0010] 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. The lifting member is configured to switch positions between the first position and the second position along a direction perpendicular to the bearing surface.

[0011] In some embodiments, the base further includes a housing, a drive member is threadedly connected to one end of the lifting member away from the bearing surface, the housing includes a limiting structure connected to the lifting member to limit circumferential rotation of the lifting member about a first direction, and the drive member rotates relative to the lifting member to drive the lifting member to move along the first direction;

[0012] Along the first direction, the end of the lifting member away from the magnetic member is provided with an external thread, and the driving member is provided with a threaded hole. The external thread and the threaded hole are engaged so that the driving member drives the lifting member to move along the first direction.

[0013] The driving component includes a driving part and a driven part. The driving part is connected to the lifting component, and the driven part is adapted to obtain driving force to drive the lifting component to a second position.

[0014] The drive unit is a hollow column with a threaded hole. The lifting component includes a threaded column and a lifting end. The threaded column is connected to the lifting end, and the lifting end is adapted to abut against the magnetically attracted device. The threaded column extends into the hollow column in a first direction to engage with the threaded drive unit.

[0015] The driven part is a knob, and a hollow column is connected to the knob. The driving component includes a connecting rib, which is arranged around the circumference of the hollow column. One end of the connecting rib is connected to the outer wall of the hollow column, and the other end is connected to the inner wall of the knob.

[0016] In some embodiments, the interior of the first end wall is recessed with a receiving groove, the lifting end can be located in the receiving groove, the housing includes an intermediate connector, the intermediate connector is disposed in the receiving groove and connected to the housing, the intermediate connector includes a limiting structure, the intermediate connector is provided with a through hole, the axial direction of the through hole is parallel to the first direction, and the lifting member passes through the through hole;

[0017] The inner wall of the through hole is recessed with a guide groove, which is configured as a limiting structure. The guide groove extends along the first direction, and the lifting member is provided with a guide protrusion that is recessed into the guide groove.

[0018] The inner wall of the through hole is recessed with multiple guide grooves, which are circumferentially spaced around the first direction. The lifting member includes multiple guide protrusions circumferentially spaced around the first direction, and the multiple guide protrusions correspond to the multiple guide grooves respectively.

[0019] The intermediate connector includes a boss protruding toward the axis of the through hole. The boss has a top wall and a bottom wall that are oppositely distributed along a first direction. Along the first direction, a guide protrusion abuts against the bottom wall of the boss to restrict the movement of the lifting member along the first direction.

[0020] In some embodiments, the base further includes a housing having a cavity and a bearing surface;

[0021] The driving component includes a first elastic element located in the cavity and connected to the lifting component. The first elastic element 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 component to move from a first position to a second position.

[0022] 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, and the lifting member 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.

[0023] The lifting component includes a lifting part and a rotating part that are threadedly connected to each other. The lifting part includes a lifting end and is slidably connected to the housing. The rotating part is fixedly connected to the first elastic element and rotatably connected to the housing. During the process of the lifting component moving from the second position to the first position, the rotating part rotates circumferentially, and the axis of rotation is perpendicular to the bearing surface, which drives the lifting part to slide in a direction parallel to the axis of rotation.

[0024] The magnetic connection device also includes a locking member, and 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 apart from the lifting member so that the first elastic force can be released.

[0025] The locking structure includes multiple locking grooves arranged at intervals along the circumference. One side wall of the locking groove along the circumference is the first groove wall, and the opposite side wall of the locking groove along the circumference is the 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 multiple locking grooves.

[0026] In some embodiments, the housing has an operating through-hole that communicates the cavity with the outside. The locking member includes a locking part and an operating part connected to each other. The operating part passes through the operating through-hole and extends out of the housing. The operating part extending out of the housing is configured to be able to extend into the cavity through the operating through-hole after obtaining driving force, and drive the locking part to move the locking member from a third position to a fourth position.

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 obtain 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.

[0028] In some embodiments, the base further includes a housing having a cavity and a bearing surface;

[0029] The drive unit includes a lever, one end of which protrudes outside the housing. The lever is connected to the lifting member in a driving manner and can rotate relative to the housing to switch the lifting member between a second position and a first position.

[0030] The magnetic component also includes a connecting component. The lever is connected to the lifting component via the connecting component. The connecting component is located inside the housing and fixed to the lever.

[0031] The lifting member includes a first abutting part, and the connecting member includes a second abutting part. When the connecting member rotates together with the lever in a first rotation direction, the second abutting part can push the first abutting part so that the lifting member moves from the first position to the second position. When the connecting member rotates together with the lever in a second rotation direction, the lifting member moves from the second position to the first position. The first rotation direction is opposite to the second rotation direction.

[0032] In some embodiments, the first abutting portion includes a first inclined surface that is inclined circumferentially along the connector, and the first inclined surface abuts against the second abutting portion;

[0033] Alternatively, the second abutment portion includes a second inclined surface that is circumferentially inclined along the connector, and the second inclined surface abuts against the first abutment portion;

[0034] Alternatively, the first abutting portion includes a first inclined surface that is inclined circumferentially along the connector, and the second abutting portion includes a second inclined surface that is inclined circumferentially, with the first inclined surface and the second inclined surface fitting together.

[0035] A second aspect of the present invention also provides a magnetic connection device for effortlessly removing magnetically attached devices, comprising:

[0036] The first magnetic element is suitable for adsorbing magnetically attached devices;

[0037] The second magnetic component is sleeved on the first magnetic component and spaced apart from the first magnetic component. The second magnetic component is suitable for adsorbing magnetically attached devices.

[0038] The housing has a cavity extending along a first direction, the cavity having a first opening and a second opening in the first direction, and a first magnetic member is mounted on the side of the housing located at the first opening;

[0039] The driving component includes a rotating part and a lifting part. The rotating part is rotatably connected to the housing and protrudes from the second opening. The lifting part is threadedly connected to the rotating part. The second magnetic member is installed on the side of the lifting part away from the rotating part. The driving component is configured to drive the second magnetic member to move along a first direction so that the second magnetic member can switch positions between a first position and a second position.

[0040] The rotating part is configured to rotate relative to the housing so that the lifting part moves relative to the housing in the first direction. When the second magnetic member is in the second position, the side wall of the second magnetic member away from the lifting part protrudes from the side wall of the first magnetic member away from the second opening. When the second magnetic member is in the first position, the side wall of the second magnetic member away from the lifting part is flush with the side wall of the first magnetic member away from the second opening.

[0041] The rotating part has a cavity on the side facing the first opening, and the cavity has a first threaded structure extending toward the lifting part. The lifting part has a second threaded structure on the side facing the second opening. The second threaded structure is inserted into the cavity and threadedly connected to the first threaded structure.

[0042] A third aspect of the present invention also provides a magnetic attraction accessory, characterized in that it comprises:

[0043] The housing, the outer surface of which includes the bearing surface;

[0044] Magnetic components are housed within the casing;

[0045] The lifting member is movably connected to the housing and can switch between a first position and a second position. When the lifting member is in the second position, the lifting member protrudes away from the housing relative to the bearing surface, and the protrusion distance of the lifting member is a first distance. When the lifting member is in the first position, the lifting member protrudes away from the housing relative to the bearing surface, is flush with the bearing surface, or is located inside the housing. When the lifting member protrudes away from the housing relative to the bearing surface, the protrusion distance of the lifting member is a second distance, and the first distance is greater than the second distance.

[0046] The driving component includes a button that is slidably connected to the housing. The button abuts against the lifting component and can drive the lifting component to move, so that the lifting component switches between a first position and a second position. The driving component includes two buttons that are spaced apart along a second direction, which is the sliding direction of the buttons.

[0047] Compared with the prior art, the beneficial effects of the present invention are:

[0048] When the lifting component is in the first position, its lifting end is located on the side of the bearing surface away from the magnetically attached device. This means that the lifting component does not lift the magnetically attached device at this time, and the magnetically attached device and the base maintain a stable assembly state. When the lifting component switches to the second position, the lifting end moves to the side of the bearing surface facing the magnetically attached device, and at least partially pushes the magnetically attached device away from the bearing surface for easy access by the user. The drive component is connected to the lifting component and is responsible for providing power to enable the lifting component to move in a specific direction, realizing the position switching. This process not only simplifies the separation operation of the magnetically attached device and the bracket, but also improves the user experience.

[0049] Specifically, since the bearing surface includes a magnetic component, when the magnetically attachable device is fixed to the bracket, it will be magnetically attracted to the bracket by the magnetic component. The lifting component lifts the magnetically attachable device along the first direction, which weakens the magnetic component's attraction to the magnetically attachable device. Therefore, the bracket's binding force on the magnetically attachable device is reduced, making it easier to remove the magnetically attachable device. Attached Figure Description

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 invention.

[0092] The following is for reference. Figures 1 to 8 To describe the magnetic connection device according to embodiments of the present invention. (Refer to...) Figures 1 to 4 The magnetic connection device of the present invention includes a base 10, a lifting member 300, and a driving member 400. The base 10, as the core part of the magnetic connection device, has a bearing surface 110 suitable for supporting magnetically attachable devices. The base 10 includes a magnetic member 200, which is adapted to magnetically attach magnetically attachable devices supported on the bearing surface 110. In other words, the magnetic member 200 is used to enhance the attraction force on the magnetically attachable devices placed thereon, ensuring that the devices will not easily slip off during use.

[0093] It is understood that the magnetic component 200 can be an embedded magnet or a surface-exposed magnet, with the bearing surface 110 of the base 10 itself configured to be magnetic, and one surface of the magnetic component 200 serving as the bearing surface 110. It is also understood that in some embodiments, the magnetic component 200 plays an auxiliary role in fixing the magnetically attachable device to the magnetic connection device; that is, other structures are used to fix the magnetically attachable device to the magnetic connection device, and the adsorption effect of the magnetic component 200 is used in conjunction with other fixing structures to securely fix the magnetically attachable device to the magnetic connection device.

[0094] Regarding the definition of magnetically attachable devices, it can be understood that a magnetically attachable device can refer to the device itself, such as a bare device like a mobile phone, tablet, computer, or e-reader, or it can refer to a combination of the device itself and a protective case fitted onto the device, such as a mobile phone or tablet with a protective case. The magnetic component 200 can magnetically attach to either the device itself or the protective case fitted onto the device.

[0095] A lifting member 300 is movably connected to a base 10 and is configured to switch positions relative to the base 10 between a first position and a second position. A drive member 400 is connected to the lifting member 300 and is configured to drive the lifting member 300 to move along a first direction X, thereby moving the lifting member 300 from the first position to the second position.

[0096] When the lifting member 300 is in the first position, its lifting end 320 is located on the side of the bearing surface 110 facing away from the magnetically attachable device. This means that the lifting member 300 does not lift the magnetically attachable device at this time, and the magnetically attachable device and the base 10 maintain a stable assembly state. When the lifting member 300 switches to the second position, the lifting end 320 moves to the side of the bearing surface 110 facing the magnetically attachable device and pushes the magnetically attachable device at least partially away from the bearing surface 110 for easy access by the user. The driving member 400 is connected to the lifting member 300 and is responsible for providing power to enable the lifting member 300 to move in a specific direction to achieve position switching. This process not only simplifies the separation operation of the magnetically attachable device and the magnetic connection device but also improves the user experience. Specifically, since the base 10 includes a magnetic component 200, when the magnetically attachable device is fixed to the magnetic connection device, it will be magnetically attracted to the magnetic connection device by the magnetic component 200. The lifting component 300 lifts the magnetically attachable device along the first direction X, thereby weakening the magnetic component 200's attraction to the magnetically attachable device. As a result, the magnetic connection device's binding ability to the magnetically attachable device is reduced, making it easier to remove the magnetically attachable device.

[0097] Regarding the bearing surface 110, it can be understood that the bearing surface 110 is a general term for the surface that supports the magnetically attached device after it is fixed to the magnetic connection device. Specifically, the bearing surface 110 can be the outer shell of the base 10, the end face of the magnetic component 200 or the lifting component 300, or any combination of the above structures configured as the bearing surface 110. When the lifting component 300 is in the first position, the upper end face of the lifting component 300 can be separated from the magnetically attached device, that is, at this time the bearing surface 110 includes the surface of the base 10. In the first position, the upper end face of the lifting component 300 can also contact the magnetically attached device, at which time the bearing surface 110 includes the surface of the base 10 and the surface of the lifting component 300. When the lifting member 300 is in the second position, the magnetic device is lifted by the lifting member 300, and at least part of the outer wall of the magnetic device that was originally attached to the upper surface of the base 10 is separated from the upper surface of the base 10. As a result, the base 10’s control over the magnetic device is weakened, making it easier for the user to take away the magnetic device.

[0098] It is understandable that the effect of the lifting member 300 on the magnetically oriented device in the second position can vary. For example, in the second position, the lifting member 300 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 base 10 have no contact area, and the magnetically oriented device and the outer wall of the base 10 are completely separated. In some embodiments, the lifting member 300 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 base 10 under the action of the lifting member 300, reducing the contact area between the two compared to the original contact area, decreasing the base 10's control over the magnetically oriented device, and facilitating the removal of the magnetically oriented device.

[0099] Of course, in some embodiments, the lifting member 300 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 300. In some embodiments, the lifting member 300 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 110. Here, lifting away refers to reducing the binding force of the magnetic connection device on the magnetically attached device, not necessarily completely separating it. Furthermore, when the lifting member 300 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 110.

[0100] In some embodiments, the lifting member 300 can also push away the magnetically attached device from the side. For example, the magnetically attached device is attached to the bearing surface 110 in the vertical direction. Through the linkage structure, the lifting member 300 pushes away the magnetically attached device in the horizontal direction, thereby reducing the contact area between the magnetically attached device and the bearing surface 110 and weakening the binding ability of the magnetic member 200 on the magnetically attached device.

[0101] In some embodiments, a receiving groove 111 is recessed inside the first end wall, and the lifting end 320 can be located within the receiving groove 111. The lifting member 300 is driven by a combination of a knob and a screw. Specifically, a rotatable knob is provided on the housing 100, and the knob is connected to a screw. The screw extends into the receiving groove 111 and is threadedly connected to the lifting member 300. The driving member 400 includes the knob, and the lifting member 300 includes the screw. When the user rotates the knob, the screw rotates, and the lifting member 300 moves linearly along the first direction X under the action of the screw, thereby switching between the second position and the first position. This driving method has a simple structure, low cost, and is easy to operate. The user can precisely adjust the position of the lifting member 300 by controlling the rotation angle and direction of the knob.

[0102] In some embodiments, the lifting member 300 is driven by a pull rod. Specifically, a retractable pull rod is provided on one side of the housing 100, and the pull rod is connected to the lifting member 300 via a linkage or other transmission mechanism, wherein the lifting member 300 includes the pull rod. The user moves the lifting member 300 within the receiving groove 111 by pulling or pushing the pull rod. The outer end of the pull rod can be designed in a shape that is easy to grip, and a corresponding limiting device is provided on the housing 100 to prevent the pull rod from being pulled out or pushed in excessively. This driving method is more intuitive, and the user can directly control the extension and retraction of the lifting member 300 by pulling or pushing the pull rod.

[0103] In some embodiments, the lifting member 300 is driven by a gear and rack mechanism. Specifically, the driving member 400 is a gear, and the lifting member 300 is provided with a matching rack. The user drives the gear to rotate, causing the rack to move linearly, thereby moving the lifting member 300 within the receiving groove 111.

[0104] In some embodiments, the lifting member 300 is driven by electromagnetic drive, utilizing the principle of electromagnets to drive the lifting member 300. Specifically, an electromagnet coil is installed at an appropriate position within the receiving groove 111, and the lifting member 300 is made of magnetic material or has magnetic components fixed to it. The magnetic connection device can be designed to have wireless charging functionality, be energized, and have a dedicated button to control the energization of the electromagnet. When the electromagnet is energized, it generates a magnetic field that attracts or repels the lifting member 300, causing it to move along the first direction X. By designing the direction and magnitude of the current in the electromagnet, the lifting member 300 can be switched between a second position and a first position. The advantages of electromagnetic drive are fast response speed, enabling the lifting member 300 to complete its movement in a short time, and the movement speed and force of the lifting member 300 can be adjusted by precisely controlling the current. Furthermore, when configured as an electromagnetic drive, the driving member 400 functions as a corresponding button; simply adjusting the button position to a location convenient for user operation greatly improves the ease of user control of the magnetic connection device.

[0105] In some embodiments, the design of the lifting member 300 can incorporate a multi-segment lifting mechanism in addition to basic linear motion. For example, the lifting member 300 can be divided into multiple parts, each moving sequentially to form a stepped lifting process. The lifting member 300 may slightly pause at several nodes along the first direction X to provide feedback on the lifting motion. This design can more gently release the contact between the magnetically attached device and the supporting surface 110, reducing the impact force caused by sudden lifting. Additionally, adding a soft material, such as a silicone pad, to the end of the lifting member 300 can be considered to protect the magnetically attached device from damage.

[0106] It is understood that in some embodiments, the driving member 400 and the lifting member 300 may be two parts of a single integrated component. For example, the driving member 400 and the lifting member 300 may be considered as a single unit, ultimately enabling the end of the lifting member 300 to lift the magnetically attached device, thereby detaching the magnetically attached device entirely or partially from the bearing surface 110. All of the above design methods fall within the protection scope of this invention.

[0107] In some embodiments, the operation of the drive unit 400 is not limited to manual adjustment; it can integrate an electric motor and a remote control device, allowing users to remotely control the movement of the lifting unit 300, greatly improving the flexibility and convenience of operation.

[0108] In some embodiments, to enhance the friction between the bearing surface 110 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 110, 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 110 contacts the device, providing both cushioning and improved user experience. Since the end of the lifting member 300 also contacts the magnetically attachable device, in some embodiments, a silicone top cover 600 is provided at the end of the lifting member 300 to protect the magnetically attachable device. The top cover 600 can be connected to the end of the lifting member 300 by sleeve or by fitting.

[0109] In some embodiments, considering that different users may use magnetically attached devices of various sizes, the size of the bearing surface 110 is designed to be adjustable. For example, a retractable frame is provided on one or both sides of the bearing surface 110, and fixed by a structure such as a slide rail or elastic buckle. The user can adjust the length of the frame according to the actual size of the device, thereby accommodating magnetically attached devices of different widths. In addition, the overall area of ​​the bearing surface 110 can also be designed to be expandable, such as by adding a foldable extension. When a larger device needs to be placed, the extension can be unfolded to expand the area of ​​the bearing surface 110, and then folded back after placement to maintain the compactness of the magnetic connection device.

[0110] In some embodiments, considering that excessive magnetism of the magnetic component 200 may affect the internal structure of the magnetically attached device, the bearing surface 110 is designed with an auxiliary fixing structure to cooperate with the magnetic component 200 and further enhance the fixing effect on the magnetically attached device. For example, some adjustable clips or elastic straps are provided at the edge of the bearing surface 110. The user can adjust the position of the clips or the tightness of the straps according to the thickness and shape of the device to fix the device more firmly on the bearing surface 110. The auxiliary fixing structure compensates for insufficient magnetic strength of the magnetic component 200 and prevents the device from slipping off the bearing surface 110 due to accidental collisions or its own weight.

[0111] Reference Figure 1 and Figure 3 In some embodiments, the base 10 includes a housing 100, and a magnetic element 200 is disposed within the housing 100. The housing 100 has a first end wall 130, and the bearing surface 110 includes the first end wall 130. In other words, the magnetic element 200 is not exposed, and only the exposed surface of the housing 100, i.e., the first end wall 130, is used to support the magnetically attached device.

[0112] In some embodiments, the base 10 includes a housing 100, a magnetic element 200 connected to the housing 100, the magnetic element 200 having a second end wall 210, and a bearing surface 110 including the second end wall 210. This embodiment can be understood as the surface of the magnetic element 200 being exposed, and the magnetically attracted device being supported only by the exposed surface of the magnetic element 200, i.e., the bearing surface 110 including the second end wall 210.

[0113] In some embodiments, the base 10 includes a housing 100 having a first end wall 130, a magnetic element 200 connected to the housing 100 having a second end wall 210, and a bearing surface 110 including the first end wall 130 and the second end wall 210. This embodiment is intended to illustrate that the bearing surface 110 can be formed by the structure of the housing 100 and the structure of the magnetic element 200. And / or, in some embodiments, the base 10 includes a housing 100 having a first end wall 130, the magnetic element 200 disposed within the housing 100, and a lifting end 320 having a third end wall 340. When the lifting element 300 is in a first position, the first end wall 130 and the third end wall 340 are coplanar, and the bearing surface 110 and the third end wall 340 jointly serve to support the magnetically attracted device. This embodiment means that the structure of the lifting end 320 can also be configured as the bearing surface 110. In summary, the bearing surface 110 can come from any one of the magnetic components 200, the housing 100, and the lifting end 320, or any combination of two or three structures.

[0114] Reference Figures 4 to 6 In some embodiments, the lifting member 300 is configured to switch between a first position and a second position along a direction perpendicular to the bearing surface 110. This design allows the lifting member 300 to lift and lower the magnetically attached device without changing its direction of movement, thereby simplifying the mechanical structure design and improving operational accuracy. When the lifting member 300 is in the first position, it is completely hidden inside or close to the surface of the base 10, ensuring that the magnetically attached device can be placed stably on it; while when the lifting member 300 moves to the second position, the lifting end 320 extends and contacts the magnetically attached device, pushing it away from the bearing surface 110 a distance for easy access by the user. This process is achieved by the power provided by the driving member 400, which converts mechanical energy into linear motion of the lifting member 300, ensuring smoothness and stability of the operation.

[0115] Understandably, in some embodiments, to further improve the operational accuracy of the lifting member 300, a pressure sensor can be installed on the top of the lifting member 300. This sensor can detect the applied pressure when the lifting member 300 contacts the magnetically attached device, thereby controlling the rising speed and stopping time of the lifting member 300 to avoid damage to the device. For example, when the lifting member 300 begins to push the magnetically attached device, if the detected pressure value exceeds a preset safety threshold, the system will automatically slow down the speed of the lifting member 300 or stop its further ascent. Furthermore, considering that the height of the magnetically attached device needs to be frequently adjusted in certain special situations, an electric adjustment device can be introduced, allowing the position adjustment of the lifting member 300 to be completed via a button or remote control, eliminating the need for manual operation and greatly improving the user experience.

[0116] Reference Figures 1 to 4 In some embodiments, the base 10 includes a housing 100, with the magnetic component 200 disposed within the housing 100. The housing 100 has a first end wall 130, and the bearing surface 110 also includes the first end wall 130. To accommodate the lifting component 300, a receiving groove 111 is recessed inside the first end wall 130, and the lifting component 300 is placed within this receiving groove 111. When the lifting component 300 is in the first position, the lifting end 320 is located on the side of the first end wall 130 facing the opposite direction, or the lifting end 320 is located within the opening of the receiving groove 111, meaning the lifting component 300 does not extend out of the receiving groove 111 and does not interfere with the normal placement of the magnetically attached device. When the lifting component 300 is driven to the second position, the lifting end 320 extends at least partially out of the opening of the receiving groove 111, pushing the magnetically attached device upwards. This design not only makes the overall appearance of the magnetic connection device more concise and aesthetically pleasing but also increases the convenience and safety of use. The presence of the receiving groove 111 also provides additional protection, preventing external dust or other impurities from entering and affecting the working performance of the lifting member 300. Furthermore, the receiving groove 111 can be designed with a certain depth and width to accommodate lifting members 300 of different sizes, thereby expanding the application range of the magnetic connection device.

[0117] Understandably, in some embodiments, to enhance the stability and durability of the magnetic connection device, the housing 100 can be made of high-strength aluminum alloy or carbon fiber composite material. This not only reduces the overall weight but also increases impact resistance. Regarding the design of the receiving groove 111, in addition to the existing single opening, an auxiliary opening can be added to the side to facilitate maintenance and replacement of components such as the lifting component 300. For example, when cleaning or repairing the lifting component 300 is required, it can be easily removed through the side opening without disassembling the entire magnetic connection device. Furthermore, to prevent increased friction between the lifting component 300 and the receiving groove 111 after prolonged use, a low-friction coefficient wear-resistant coating, such as Teflon (PTFE), can be applied to the inner wall of the receiving groove 111, reducing wear and noise. Such improvements allow the lifting component 300 to maintain good working condition even after multiple lifting operations, extending the service life of the magnetic connection device.

[0118] Reference Figures 1 to 4In some embodiments, the drive member 400 is configured not only to drive the lifting member 300 from a first position to a second position, but also to drive the lifting member 300 back from the second position to the first position. This bidirectional drive design makes the operation of the lifting member 300 more flexible, allowing the position of the magnetically attached device to be adjusted according to actual needs. For example, when the user wants to reposition the magnetically attached device on the support surface 110, the lifting member 300 can smoothly return to its original position through the action of the drive member 400, ensuring that the magnetically attached device can be safely placed back on the base 10. This process relies on the drive member 400, which can achieve the up-and-down movement of the lifting member 300 by changing the direction of the force applied to it.

[0119] For example, the first direction X is the vertical direction, defined as upward and downward for ease of description. Initially, the lifting member 300 is in the first position, with the lifting end 320 located on the side of the bearing surface 110 away from the magnetically attachable device, and the entire magnetic connection device is in standby mode. When it is necessary to lift the magnetically attachable device, the driving member 400 provides upward force, causing the lifting member 300 to move upward along a direction perpendicular to the bearing surface 110 until it reaches the second position. The lifting end 320 extends and contacts the magnetically attachable device, pushing it away from the bearing surface 110. To return the lifting member 300 to the first position, the driving member 400 reverses direction, generating a downward driving force, causing the lifting member 300 to move downward along the same path until the lifting end 320 is again hidden inside the base 10 or flush with the bearing surface 110. This design ensures reversibility of operation and improves ease of use and safety.

[0120] It is understandable that the drive unit 400 can also be configured to provide only upward driving force to eject the magnetically attached device. No special design is made for whether the drive unit 400 can return to the receiving slot 111. The purpose of this invention is to lift the magnetically attached device so that it is easy for the user to take it away. Therefore, the drive unit 400 only needs to meet the condition of being able to lift the magnetically attached device.

[0121] Of course, in some embodiments, after the drive member 400 lifts the magnetically attachable device, when a new magnetically attachable device is placed on the magnetic connection device, the drive member 400 can be configured to move downwards and return to the receiving slot 111 under the gravity of the new magnetically attachable device. Alternatively, a new structure can be provided to allow the lifting end 320 to move downwards, and this structure is not the same as the original drive member 400 that drives the lifting member 300 upwards.

[0122] It is understandable that the drive unit 410 may also be configured with some positioning structures so that the lifting member 300 can be positioned at a certain position along the first direction X under the action of the drive unit 410, that is, the distance between the end of the lifting member 300 and the first end wall 130 of the housing 100 remains unchanged. Such positioning structures can be in various forms such as snap-fits and pins, depending on the specific structure of the housing 100.

[0123] Reference Figure 4 and Figure 6 In some embodiments, the drive unit 400 includes two parts: a drive unit 410 and a driven unit 440. The drive unit 410 is directly connected to the lifting member 300, and the driven unit 440 is responsible for receiving external driving force and transmitting it to the drive unit 410, thereby pushing the lifting member 300 to the second position. Specifically, the driven unit 440 can be a manual knob, an electric motor, or other form of power source. When the driven unit 440 receives a user command or a signal from an automated control system, it starts and transmits the generated mechanical energy to the drive unit 410. The drive unit 410 uses this energy to drive the lifting member 300 to move along a predetermined path.

[0124] For example, if an electric motor is used as the driven part 440, the torque generated by the motor's rotation will be converted into linear motion through a series of gears or linkages, acting on the drive part 410. The drive part 410 then transmits this linear motion to the lifting member 300, causing it to rise or fall in a direction perpendicular to the bearing surface 110. This method not only effectively improves the operating efficiency of the lifting member 300 but also ensures the accuracy and stability of its movements. Furthermore, due to the tight fit between the drive part 410 and the driven part 440, good synchronization performance can be maintained even after prolonged use, reducing maintenance costs. Similarly, the driven part 440 can also be a knob, which the user rotates to drive the lifting member 300 to move.

[0125] It is understood that in some embodiments, the driven part 440 of the drive member 400 can use a pneumatic or hydraulic system instead of a conventional electric motor. For example, compressed air or hydraulic oil can be used as the power medium to drive the lifting member 300 through a cylinder or hydraulic cylinder. The advantage of this approach is that it can provide greater output force, making it particularly suitable for supporting heavier magnetically attached devices. For example, lifting a large monitor or server equipment may be difficult with a small electric motor alone, while a pneumatic or hydraulic system can easily handle the task. In addition, because fluid transmission has better cushioning characteristics, the vibration and noise generated throughout the process are also less, improving the user experience. For example, when using a pneumatic system, the rising speed of the lifting member 300 can be easily controlled by adjusting the opening of the air inlet valve, while ensuring a smooth transition of movement.

[0126] Reference Figure 5 and Figure 6 In some embodiments, the base 10 includes a housing 100, with the drive unit 410 located within the housing 100 and the driven unit 440 extending out of the housing 100. This design protects the internal components of the drive unit 400 (such as gears, linkages, etc.) while facilitating operation of the driven unit 440 by a user or external device. First, the housing 100 provides structural support and houses the drive unit 410. The drive unit 410 and the lifting member 300 are mechanically connected to transmit force, ensuring that the lifting member 300 can move smoothly along the first direction X. Specifically, the drive unit 410 can be an electric motor or a manual screw mechanism, with its output shaft directly or indirectly connected to the lifting member 300. The driven unit 440 is the user-interactive part, extending from the housing 100 for easy user operation. For example, when a manual knob is used as the driven unit 440, the rotational movement of the knob is converted into power input to the drive unit 410, causing the drive unit 410 to produce a corresponding linear movement, pushing the lifting member 300 up and down. This design not only improves ease of operation but also enhances the stability of the overall structure.

[0127] Reference Figure 5 and Figure 6 In some embodiments, the drive member 400 rotates about a first direction X to drive the lifting member 300 to move along the first direction X to a second position. In this embodiment, the rotational motion of the drive member 400 is converted into the linear motion of the lifting member 300. For example, one end of the lifting member 300 is provided with an external thread, and the drive member 400 is provided with a threaded hole, the two engaging with each other. When the drive member 400 rotates, the lifting member 300 will move forward or backward along the direction of the thread.

[0128] In some embodiments, the magnetic connection device of the present invention includes a housing 100, a magnetic component 200, a lifting component 300, and a driving component 400. The housing 100 has a bearing surface 110 suitable for supporting a magnetically attracted device. The bearing surface 110 is recessed with a receiving groove 111 for accommodating other parts of the magnetic connection device. The receiving groove 111 not only provides a hidden space for the lifting component 300, but also ensures a simple appearance and reduces the size of the magnetic connection device.

[0129] Reference Figures 1 to 3A lifting member 300 is disposed within a receiving groove 111 and connected to the housing 100. The lifting member 300 may be entirely recessed within the receiving groove 111, or only the end that abuts against the magnetically attachable device may be recessed within the receiving groove 111 while the rest of its body protrudes from the housing 100 away from the area where the magnetically attachable device is placed. A driving member 400 is connected to the lifting member 300, which is configured to have a second position and a first position. The driving member 400 drives the lifting member 300 to move along a first direction X, switching the lifting member 300 between the second and first positions. When the lifting member 300 is in the second position, the end of the lifting member 300 extends from the receiving groove 111 and abuts against the magnetically attachable device. The lifting member 300 pushes the magnetically attachable device along the extension direction, separating the magnetically attachable device from the bearing surface 110, thus separating the magnetically attachable device from the housing 100. Since the magnetic component 200 is connected to the housing 100, as the distance between the magnetically attached device and the housing 100 increases, the magnetic component 200's attraction to the magnetically attached device weakens, thus making it easier for the user to remove the magnetically attached device. For example, in some embodiments, the lifting component 300 lifts the device by 1 mm, and the magnetic force applied by the magnetic component 200 to the magnetically attached device decreases from 25 N to 15 N.

[0130] Reference Figures 1 to 3 When the lifting member 300 is in the first position, the end of the lifting member 300 is inserted into the receiving groove 111. At this time, the bearing surface 110 can closely fit the magnetically absorbing device, making the distance between the magnetically absorbing device and the magnetic member 200 closer, thereby enhancing the magnetic member 200's adsorption capacity for the magnetically absorbing device and ensuring the stable fixation of the magnetically absorbing device by the magnetic connection device.

[0131] In summary, the magnetic connection device of the present invention adjusts the distance between the magnetically attachable device and the magnetic component 200 by changing the distance between the lifting component 300 and the magnetic component 200, thereby adjusting the magnetic component 200's ability to attract the magnetically attachable device and making it easier for the user to remove the magnetically attachable device from the magnetic connection device. Furthermore, the recessed receiving groove 111 inside the bearing surface 110 facilitates the placement of the various parts of the magnetic connection device, saving space.

[0132] It should be noted that regarding the contact between the bearing surface 110 and the magnetically attachable device, the bearing surface 110 only serves a supporting function; it is not necessary for the magnetically attachable device and the bearing surface 110 to be completely in contact. Contact between the two is sufficient for contact. In some embodiments, the bearing surface 110 of the housing 100 can support the magnetically attachable device, and the end face of the lifting member 300 can also serve as the surface supporting the magnetically attachable device. Alternatively, the end face of the lifting member 300 and the bearing surface 110 of the housing 100 can jointly serve as the surface supporting the magnetically attachable device. The key point of this invention is to adjust the distance between the magnetically attachable device and the magnetic member 200 by controlling the lifting member 300. Therefore, the structure supporting the magnetically attachable device is diverse and not limited to the bearing surface 110 of the housing 100.

[0133] Reference Figure 3 and Figure 4 In some embodiments, a pressure block 500 is used to sequentially fasten the housing 100, magnetic component 200, lifting component 300, and driving component 400 together to facilitate the disassembly and assembly of the magnetic connection device.

[0134] Reference Figures 3 to 6 In some embodiments, the end of the lifting member 300 away from the bearing surface 110 is threadedly connected to the driving member 400. The housing 100 includes a limiting structure 1221 connected to the lifting member 300 to restrict the circumferential rotation of the lifting member 300 about a first direction X. The driving member 400 rotates relative to the lifting member 300 to drive the lifting member 300 to move along the first direction X. Specifically, refer to... Figures 3 to 6 In some embodiments, along the first direction X, the end of the lifting member 300 away from the magnetic member 200 is provided with an external thread, and the driving member 400 is provided with a threaded hole. The external thread and the threaded hole cooperate to allow the driving member 400 to drive the lifting member 300 to move along the first direction X. By designing one end of the lifting member 300 as a threaded structure and cooperating with the threaded hole on the driving member 400, the lifting member 300 can move smoothly along the first direction X when the driving member 400 rotates. This design not only ensures the stability and reliability of the lifting member 300, but also simplifies the mechanical transmission mechanism and reduces manufacturing costs. The function of the limiting structure 1221 is to prevent the lifting member 300 from rotating circumferentially during movement. Since the circumferential rotation of the lifting member 300 is restricted, when the driving member 400, which is threadedly connected to the lifting member 300, rotates, the lifting member 300 only moves along the first direction X. It is understandable that the limiting structure 1221 can be designed to cooperate with the lifting member 300 in the form of a pin hole, or the limiting structure 1221 can be designed as a slot or other structure, as long as it satisfies the condition of limiting the circumferential movement of the lifting member 300 along the first direction X, and does not affect the movement of the lifting member 300 along the first direction X.

[0135] Furthermore, referring to Figures 3 to 6 as well as Figure 8 The drive component 400 includes a drive portion 410 and a connecting structure 420. The connecting structure 420 is connected to the housing 100, and the drive portion 410 is connected to the connecting structure 420. Along the first direction X, the drive portion 410 protrudes from the connecting structure 420 on the side away from the housing 100. By configuring the drive assembly in the form of a combination of the drive portion 410 and the connecting structure 420, with the drive portion 410 protruding outward and the connecting structure 420 integrated into the housing 100, this design allows for a thinner structure in the main area of ​​the magnetic connection device, facilitating space utilization.

[0136] Reference Figures 3 to 6 as well as Figure 8In some embodiments, the drive unit 410 is a hollow column 411 with a threaded hole. The lifting member 300 includes a threaded column 310 and a lifting end 320. The threaded column 310 is connected to the lifting end 320, which is adapted to abut against a magnetically attached device. The threaded column 310 extends into the hollow column 411 along a first direction X to thread with the drive unit 410. In this embodiment, the drive unit 410 acts as a knob for adjusting the position of the lifting member 300 along the first direction X. The hollow column 411 protrudes from the connecting structure 420 along the first direction X, that is, it protrudes from the housing 100 along the first direction X. Therefore, the length of the hollow column 411 is not affected by the thickness of the core part of the housing 100. That is, the thread of the hollow column 411 can be designed to be longer, and a longer threaded column 310 can be inserted. Thus, this design allows for the design of a lifting member 300 that can move a longer distance along the first direction X. Of course, the control accuracy of the drive component 400 on the lifting component 300 can also be adjusted by changing the parameters of the thread.

[0137] Understandably, in some embodiments, to more intuitively reflect the control of the lifting member 300 by the drive member 400, the housing 100 and the drive member 400 are provided with corresponding markings. For example, the housing 100 is provided with different numerical markings around the first direction X, and the drive member 400 is provided with a pointer protruding around the first direction X. By rotating the drive member 400, the pointer will correspond to different markings, thereby making it convenient for the user to judge the distance that the lifting member 300 has moved along the first direction X.

[0138] It is understandable that, in some embodiments, the threaded connection of the lifting member 300 can be optimized in various ways. For example, using a trapezoidal thread instead of a regular triangular thread can improve the load-bearing capacity and wear resistance of the threaded pair. The trapezoidal thread has a larger contact area, reducing the risk of wear and extending service life. At the same time, the trapezoidal thread has a lower coefficient of friction, which helps to improve transmission efficiency and makes the movement of the lifting member 300 smoother.

[0139] Reference Figure 3 and Figure 5 In some embodiments, the driven part 440 is a knob connected to the hollow column 411, providing rotational force. The driving member 400 also includes a connecting rib 430, which is arranged circumferentially around the hollow column 411, with one end connected to the outer wall of the hollow column 411 and the other end connected to the inner wall of the knob, enhancing structural stability and ensuring effective transmission of rotational force.

[0140] Reference Figures 3 to 6In some embodiments, the housing 100 includes an intermediate connector 120, which is disposed within the receiving groove 111 and connected to the housing 100. The intermediate connector 120 includes a limiting structure 1221 and a through hole 121. The axis of the through hole 121 is parallel to the first direction X, and the lifting member 300 passes through the through hole 121. In this embodiment, the lifting member 300 and the intermediate connector 120 are combined in a hole-shaft fit, which increases the coaxiality of the magnetic connection device itself. The intermediate connector 120 is fixed to the housing 100. The intermediate connector 120 can be a separate part, fixed to the housing 100 by means of pin hole fit, snap fit, etc., or the intermediate connector 120 can be configured as a single structure with the housing 100. In some embodiments, the limiting structure 1221 of the intermediate connector 120 can also be two protrusions with different connection relationships to the lifting member 300. For example, around the first direction X, the lifting member 300 has two protrusions at different positions, and the protrusions of the intermediate connector 120 correspond to the protrusions. Specifically, one protrusion abuts against the side of the protrusion that is clockwise around the first direction X, and the other protrusion abuts against the side of the protrusion that is counterclockwise around the first direction X. This combination can both restrict the design of the lifting member 300 around the first direction X and meet the requirement of the lifting member 300 moving along the first direction X.

[0141] Reference Figures 3 to 6 In some embodiments, the inner wall of the through hole 121 is recessed with a guide groove 122, which is configured as a limiting structure 1221. The guide groove 122 extends along the first direction X, and the lifting member 300 is provided with a guide protrusion 330, which is recessed into the guide groove 122. In this embodiment, the limiting structure 1221 of the lifting member 300 and the intermediate connecting member 120 cooperates in the form of a groove and a protrusion. Specifically, the guide protrusion 330 is recessed into the guide groove 122. If the lifting member 300 rotates around the first direction X, the sidewalls of the guide groove 122 distributed around the first direction X will hinder the movement of the guide protrusion 330, that is, the lifting member 300 cannot rotate. Due to the threaded engagement, the lifting member 300 will move along the first direction X along the inner wall of the guide groove 122. It is understandable that the design positions of the guide protrusion 330 and the guide groove 122 have also been changed. For example, the intermediate connector 120 is equipped with the guide protrusion 330, and the lifting component 300 is equipped with the guide groove 122.

[0142] In some embodiments, in order to improve the smoothness of sliding between the sidewall of the guide groove 122 and the guide protrusion 330, a ball can be embedded in the sidewall of either the guide groove 122 or the guide protrusion 330 around the first direction X. When the two move relative to each other along the first direction X, the rotation of the ball further ensures the smoothness of their relative movement along the first direction X.

[0143] Furthermore, the invention may also include limiting elements of other forms and uses. For example, when the drive member 400 and the lifting member 300 are designed as a lever-like engagement, an elastic element is introduced to provide additional support. Specifically, a spring assembly is provided at the bottom of the lifting member 300 to provide cushioning when the lifting member 300 extends, preventing damage caused by sudden impact. In addition, the spring assembly can also help the lifting member 300 automatically reset in the second position, enhancing the automation and reliability of the system.

[0144] Reference Figures 3 to 6 In some embodiments, the inner wall of the through hole 121 is recessed with multiple guide grooves 122, which are circumferentially spaced around a first direction X. The lifting member 300 includes multiple guide protrusions 330 circumferentially spaced around the first direction X, each corresponding to a guide groove 122. For example, four guide grooves 122 can be designed, and the number of guide grooves 122 can be increased to five, six, or more, with the guide grooves 122 spaced apart on the inner wall of the through hole 121. This can better distribute the force on the lifting member 300, reduce the wear of individual guide grooves 122, and extend the service life. The design of multiple guide grooves 122 and guide protrusions 330 makes the movement of the lifting member 300 more precise and stable, enhancing the reliability and durability of the entire system.

[0145] Reference Figures 3 to 6 In some embodiments, the intermediate connector 120 includes a boss 123 protruding toward the axis of the through hole 121. The boss 123 has a top wall and a bottom wall that are oppositely distributed along a first direction X. Along the first direction X, a guide protrusion 330 abuts against the bottom wall of the boss 123 to limit the movement of the lifting member 300 along the first direction X. The boss 123 is designed to limit the range of movement of the lifting member 300. Specifically, when the guide protrusion 330 on the lifting member 300 contacts the bottom wall of the boss 123, the lifting member 300 can no longer move upward.

[0146] In some embodiments, the boss 123 is annular, and there are multiple guide protrusions 330, all of which can abut against the annular boss 123. With this design, the boss 123 can more evenly distribute the pressure on the lifting member 300, which helps to protect the structure of the lifting member 300 and prevent damage due to excessive local stress.

[0147] Understandably, the boss 123 restricts the movement of the lifting member 300 after it extends a certain distance out of the receiving groove 111 along the first direction X. Regarding the restriction that the lifting member 300 sinks a certain distance into the receiving groove 111, refer to... Figures 5 to 8In some embodiments, the lifting member 300 is restricted by the contact between the end panel of the lifting member 300 and the top end of the hollow column 411 of the driving member 400. Specifically, when the lifting member 300 moves in the opposite direction X under the action of the driving member 400, the distance between the lifting member 300 and the driving member 400 gets closer and closer. At the extreme position, the lower surface of the end panel of the lifting member 300 abuts against the upper end of the hollow column 411 of the driving member 400, thereby realizing the limitation of the lifting member 300 by the driving member 400.

[0148] Reference Figure 7 and Figure 8 In some embodiments, the magnetic element 200 is circumferentially distributed around the first direction X. For example, in some embodiments, the magnetic element 200 is a ring magnet.

[0149] In some embodiments, the magnetic component 200 can be a combination of a permanent magnet and an electromagnet. A permanent magnet is fixedly installed inside the housing 100 near the bearing surface 110, with its magnetic poles facing the bearing surface 110. It uses its own magnetic field to generate an attractive force on the magnetically attracted device. Simultaneously, an electromagnet coil is placed next to the permanent magnet or at another suitable location on the bearing surface 110. The electromagnet coil is connected to a power supply and control switch on the magnetic connection device via wires. When it is necessary to enhance the magnetic component 200's ability to attract the magnetically attracted device, such as when using the magnetic connection device in a bumpy environment, the control switch can be closed to energize the electromagnet coil, generating a magnetic field in the same direction as the permanent magnet's magnetic field. The two magnetic fields are superimposed, significantly enhancing the overall attractive force of the magnetic component 200. When it is necessary to weaken the magnetism or facilitate the removal of the magnetically attracted device, the control switch can be disconnected, and the electromagnet stops working. In this case, the magnetic component 200 relies solely on the magnetic field of the permanent magnet to attract the magnetically attracted device, resulting in a relatively weaker attractive force, which is easier for the user to operate.

[0150] In some embodiments, multiple small-sized permanent magnets are arranged in a certain array within the housing 100 below the bearing surface 110 to form a multi-pole magnetic component 200 structure. These permanent magnets can be rectangular, circular, or other shapes, with adjacent permanent magnets having opposite magnetic pole polarities, forming an alternating magnetic field distribution. For example, a 2×2 or 3×3 array can be used, or a long strip array arranged in multiple rows and columns along the length of the bearing surface 110. This multi-pole array design allows the magnetic field to be more uniformly distributed on the bearing surface 110, improving the stability and reliability of the magnetic adsorption of the device. When the magnetic adsorption device is placed on the bearing surface 110, different parts of the device will be subjected to the adsorption force of multiple magnetic poles. Even if the device experiences slight displacement or tilting, it can be pulled back to a stable position by the interaction force between different magnetic poles, effectively preventing the device from accidentally slipping during use.

[0151] See Figures 9-14The first elastic element 450 is located in the cavity 140 and connected to the lifting element 300. The first elastic element 450 is configured to lock in an elastically deformed state to store a first elastic force. After the first elastic force is released, it can drive the lifting element 300 to move from a first position to a second position. Through the elastic force of the first elastic element 450, the lifting element 300 in the first position can automatically move to the second position, thus eliminating the need for corresponding operations and making the magnetic force switching operation more convenient. Therefore, the magnetic connection device of the present invention can conveniently realize the magnetic force switching operation.

[0152] For the method by which the first elastic element 450 obtains the first elastic force, see [link to relevant documentation]. Figures 9-14 In some embodiments, one end of the first elastic member 450 is connected to the housing 100 and the other end is connected to the lifting member 300. The lifting member 300 is configured to apply a first elastic force to the first elastic member 450 during the movement from the second position to the first position. With the above configuration, the lifting member 300 can apply an elastic force to the first elastic member 450 during the position switching process, and when the first elastic member 450 is locked in the elastic deformation state, the lifting member 300 can also be locked in the first position.

[0153] For the specific settings of the lifting component 300, please refer to [link / reference]. Figures 9-14 In some embodiments, the lifting member 300 includes a lifting portion 350 and a rotating portion 360 that are threadedly connected to each other. The lifting portion 350 includes a lifting end 320 and is slidably connected to the housing 100. The rotating portion 360 is fixedly connected to the first elastic member 450 and rotatably connected to the housing 100. During the process of the lifting member 300 moving from the second position to the first position, the rotating portion 360 rotates circumferentially, and the axis of rotation is perpendicular to the bearing surface 112, thereby driving the lifting portion 350 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) will be referred to as the first direction. It is understandable that during the switching process between the first and second positions of the lifting member 300, the rotating part 360 rotates in place while the overall position remains unchanged. Since the lifting part 350 and the rotating part 360 form a threaded fit, and the lifting part 350 and the housing 100 are slidably connected in the first direction, the lifting part 350 can reciprocate along the first direction while the rotating part 360 rotates in the forward and reverse directions, thereby realizing the switching between the first and second positions.

[0154] To make the position of the lifting component 300 more stable, see Figures 9-14In some embodiments, the magnetic connection device further includes a locking member 700, and the lifting member 300 includes a locking structure 370. The locking member 700 has a third position and a fourth position. When the locking member 700 is in the third position, the locking structure 370 abuts against the locking member 700 on one side of its circumferential direction to restrict the locking member 700 from moving from the first position to the second position, and the first elastic member 450 is locked in an elastic deformation state. When the locking member 700 is in the fourth position, the locking member 700 is spaced apart from the lifting member 300 so that the first elastic force can be released. It is understood that when the locking member 700 is in the third position, it can prevent the rotation of the rotating part 360, thereby preventing the first elastic member 450 from releasing its elastic force, so that the lifting member 300 is locked in the first position. When the locking member 700 is in the fourth position, it no longer plays the above-mentioned obstructive role, and thereafter the first elastic member 450 can drive the lifting member 300 to move from the first position to the second position.

[0155] For the specific fit between locking element 700 and locking structure 370, please refer to... Figures 9-14 In some embodiments, the locking structure 370 includes a plurality of locking grooves 371 arranged circumferentially. One side wall of the locking groove 371 along the circumferential direction is a first groove wall 3711, and the opposite side wall of the locking groove 371 along the circumferential direction is a second groove wall 3712. When the locking member 700 is in the third position, the first groove wall 3711 abuts against the locking member 700. During the process of the lifting member 300 moving from the second position to the first position, the rotating part 360 rotates circumferentially relative to the locking member 700, so that the locking member 700 slides sequentially on the second groove wall 3712 of the plurality of locking grooves 371. During the switching between the first position and the second position, the locking member 700 can sequentially engage with two adjacent locking grooves 371 along the circumferential direction. To achieve precise engagement, the interval angle between the plurality of locking grooves 371 that sequentially engage with the locking member 700 can correspond to the angle rotated by the rotating part 360 after the first elastic force is released. According to the requirements, the magnitude of the first elastic force released by the first elastic element 450 can be set to be adjustable. Correspondingly, the distance at which the locking element 700 switches between the third and fourth positions can be set to be adjustable, thereby adjusting the distance at which the lifting element 300 is lifted, so as to adjust the magnitude of the magnetic attraction force after it is reduced.

[0156] To control the locking element 700, see [link / reference]. Figures 9-14In some embodiments, the housing 100 has an operating through-hole 150 communicating with the cavity 140 and the outside. The locking member 700 includes a locking part 710 and an operating part 720 connected to each other. The operating part 720 passes through the operating through-hole 150 and extends out of the housing 100. The operating part 720 extending out of the housing 100 is configured to, after receiving driving force, extend into the cavity 140 through the operating through-hole 150 and drive the locking part 710, so that the locking member 700 moves from a third position to a fourth position. The operating part 720 can drive the locking part 710 in any manner. For example, in some embodiments, the operating part 720 and the locking part 710 can be directly connected, in which case the operating part 720 and the locking part 710 move synchronously and in the same direction; see also Figures 9-14 In other embodiments, the operating unit 720 drives the locking unit 710 via a linkage transmission, such as a linkage drive, gear drive, or rack and pinion drive. More specifically, in Figures 3-7 In the illustrated embodiment, the movement direction of the operating part 720 (i.e., the extension direction of the operating through hole 150) is perpendicular to the rotation axis. The locking part 710 has a first through hole and a second through hole, both of which extend along a first direction. The locking member 700 is provided with a first shaft, which passes through the first through hole to form a rotatable connection between the operating part 720 and the locking part 710. The housing 100 or a component fixedly connected to the housing 100 (specifically, the support plate described later) is provided with a second shaft, which passes through the second through hole to form a rotatable connection between the locking part 710 and the housing 100. After the above two connections are formed, while the operating part 720 moves in a direction perpendicular to the rotation axis, it can drive the locking part 710 to rotate in a direction surrounding the second shaft, so that the locking member 700 moves from the third position to the fourth position.

[0157] To ensure that the locking element 700 automatically resets after being unlocked by the user (i.e., after the locking element 700 moves from the third position to the fourth position), please refer to [link to relevant documentation]. Figures 9-14In some embodiments, the locking member 700 further includes a second elastic member 730 and a third elastic member 740. One end of the second elastic member 730 is connected to the housing 100, and the other end is connected to the operating part 720. One end of the third elastic member 740 is connected to the housing 100, and the other end is connected to the locking part 710. When the operating part 720, which extends out of the housing 100, is configured to receive driving force, the second elastic member 730 stores a second elastic force, and the third elastic member 740 stores a third elastic force. When the operating part 720 loses driving force, both the second and third elastic forces are released, causing the locking member 700 to move from the fourth position to the third position. After the aforementioned elastic forces are released, the locking member 700 returns to its state before being driven, making operation more convenient for the user. 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 730 is sleeved on the outer side of the end of the operating part 720 near the rotating part 360, and the extension direction is the same as the direction of the driving force. The third elastic element 740 is sleeved on the outer side of the second shaft.

[0158] Regarding the position switching method of the locking element 700, in some other embodiments, the position switching of the locking element 700 can be controlled by any other suitable structure, or it can also be controlled by an electric drive.

[0159] See Figures 9-14 In some embodiments, the lifting member 300 further includes a support plate located in the cavity 140. Along a direction parallel to the rotation axis, one end of the first elastic member 450 is fixedly connected to the rotating part 360, and the other end passes through the support plate and is fixedly connected to the housing 100. During the movement of the lifting member 300 from the second position to the first position, the rotating part 360 applies a first elastic force to the first elastic member 450. It is understood that the support plate is disposed between the rotating part 360 and the first elastic member 450, and since the first elastic member 450 passes through the support plate (specifically, it may pass through a through hole in the middle of the support plate), the support plate, while supporting and rotatably connecting the rotating part 360, will not move together with the rotating part 360 and the first elastic member 450. To further utilize the structure of the support plate, a mounting groove can be provided on the side of the support plate near the locking member 700 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 740 and the second shaft described in the aforementioned embodiment can be fixedly connected to the support plate.

[0160] like Figure 15 and Figure 16As shown, one end of the lever 460 protrudes outside the housing 100, and the lever 460 is kinetically connected to the lifting member 300. How the lever 460 and the lifting member 300 are kinetically connected will be explained in detail below. The lever 460 can rotate relative to the housing 100, thereby switching the lifting member 300 between a second position and a first position. This switching can be simply the lifting member 300 moving from the first position to the second position, or simply the lifting member 300 moving from the second position to the first position, or the lifting member 300 moving from the second position to the first position and then back to the second position. Figure 17 As shown, the magnetic component 200 also includes a pin located inside the housing 100 and inserted into the housing 100. For example, the pin 113 is inserted into the bottom cover of the housing 100. One end of the lever 460 located inside the housing 100 is fitted onto the outside of the pin, allowing the lever 460 to rotate about the pin, thereby enabling it to rotate relative to the housing 100. Figure 15 In the middle, the lifting component 300 is in the first position, at which point the lifting end 320 is flush with the bearing surface 110. Figure 16 In the middle, the lifting member 300 is in the second position, the lifting end 320 is located outside the housing 100, and the lifting end 320 protrudes relative to the bearing surface 110.

[0161] The following explains how lever 460 drives lifting component 300.

[0162] like Figure 17 As shown, the axis of rotation of the lever 460 relative to the housing 100 is the reference line, and the central axis of the pin is also the reference line. The lifting member 300 moves along the reference line when moving between the second and first positions. Figure 17 Taking the direction as an example, the baseline is a straight line extending in the up-down direction. The lever 460 can rotate left and right, and the lifting component 300 can move up and down. Under the above configuration, the movement path of the lever 460 when rotating does not interfere with the movement path of the lifting component 300, and both the lever 460 and the lifting component 300 can move smoothly.

[0163] The outer surface of the housing 100 also includes a back surface and a side surface, with the back surface facing away from the bearing surface 110. The side surface is located between the back surface and the bearing surface 110, with its upper and lower ends connected to the bearing surface 110 and the back surface, respectively, and surrounds the edge of the bearing surface 110. The side surface is provided with a clearance opening (e.g., clearance opening...). Figure 16 As shown, the lever 460 passes through the clearance opening and extends from the side to the outside of the housing 100. In this configuration, the lever 460 is located on the side rather than on the bearing surface 110, and the magnetically attached device connected to the magnetic component 200 does not easily obstruct the user's contact with and operation of the lever 460.

[0164] like Figure 17As shown, a stepped groove 820 is formed on the outer surface of the housing 100, and a portion of the lifting member 300 is accommodated within the stepped groove 820. A guide hole 830 is provided on the bottom wall of the stepped groove 820, and the lifting member 300 includes a guide post 810, which is slidably disposed within the guide hole 830. In this way, the lifting member 300 can slide up and down relative to the housing 100, and the sliding engagement between the guide post 810 and the guide hole 830 guides the movement of the lifting member 300. The stepped groove 820 also positions and guides the lifting member 300.

[0165] like Figure 17 As shown, the magnetic component 200 also includes a connecting member 220, which is located inside the housing 100 and fixedly connected to the lever 460. A pin passes through both the lever 460 and the connecting member 220, and the connecting member 220 can also rotate around the pin. The lever 460 and the connecting member 220 can rotate synchronously. The lifting component 300 includes a first abutment portion, and the connecting member 220 includes a second abutment portion. When the connecting member 220 rotates together with the lever 460 in a first rotation direction, the second abutment portion pushes the first abutment portion, thereby moving the lifting component 300 from a first position to a second position. Conversely, when the connecting member 220 and the lever 460 rotate together in a second rotation direction, the lifting component 300 moves from the second position to the first position. The first rotation direction is opposite to the second rotation direction; for example, if the first rotation direction is counterclockwise, then the second rotation direction is clockwise. In this way, the lever 460 is connected to the lifting member 300 through the connector 220, and the rotation of the lever 460 is converted into the linear motion of the lifting member 300.

[0166] Specifically, the first abutting portion includes a first inclined surface that is circumferentially inclined along the connector 220, and the second abutting portion includes a second inclined surface that is circumferentially inclined along the connector 220. The first and second inclined surfaces are in contact with each other. The first inclined surface extending circumferentially along the connector 220 means that, in the circumferential direction of the connector 220, the first inclined surface includes a first end and a second end, and the distance between the first inclined surface and the lifting end 320 gradually increases from the first end to the second end. The first end can be the front end of the first inclined surface, and the second end can be the rear end of the first inclined surface. Similarly, the second inclined surface extending circumferentially along the connector 220 means that, in the circumferential direction of the connector 220, the second inclined surface includes a third end and a fourth end, and the distance between the second inclined surface and the lifting end 320 gradually increases from the third end to the fourth end. The third end can be the front end of the second inclined surface, and the fourth end can be the rear end of the second inclined surface.

[0167] When the connecting member 220 rotates along the first rotation direction, the second inclined plane rotates relative to the first inclined plane. The force exerted by the second inclined plane on the first inclined plane has an upward component, which pushes the lifting member 300 upward, thereby moving the lifting member 300 from the first position to the second position. This embodiment converts the rotation of the connecting member 220 into the linear motion of the lifting member 300 through the movement and contact between the inclined planes. This embodiment has a simple structure and low cost. It should be noted that since the guide post 810 of the lifting member 300 is inserted into the guide hole 830 of the housing 100, the wall of the guide hole 830 limits the lateral movement of the guide post 810, and the force exerted by the second inclined plane on the first inclined plane will not push the lifting member 300 to rotate.

[0168] In other embodiments not shown, the first abutment portion may have a first inclined surface, but the second abutment portion may not have a second inclined surface; the second abutment portion pushes the first inclined surface through a portion of other shape. Alternatively, the second abutment portion may have a second inclined surface, but the first abutment portion may not have a first inclined surface. As long as at least one of the first and second inclined surfaces is present, the rotation of the connector 220 can be converted into the linear motion of the lifting member 300. For example, the first abutment portion has a first inclined surface, the connector 220 is configured as a cam, the connector 220 does not have a second inclined surface, and the protruding end of the cam is the second abutment portion; as the cam rotates, when the protruding end of the cam abuts against the first inclined surface, the cam lifts the first lifting member 300 upward.

[0169] Furthermore, to convert the rotation of the lever 460 into the linear motion of the lifting member 300, other transmission methods can be used between the lever 460 and the lifting member 300. For example, the second abutment portion can directly serve as part of the lever 460 (equivalent to omitting the connecting member 220), and the lever 460 can directly abut against the lifting member 300 to drive its movement. Another example is that the connecting member 220 includes a threaded hole, and the lifting member 300 includes a threaded rod connected to the threaded hole. Based on the threaded fit between the threaded hole and the threaded rod, when the connecting member 220 rotates, the threaded hole rotates relative to the threaded rod, causing the threaded rod to move axially, thereby moving the lifting member 300. Examples are not exhaustive here.

[0170] In some embodiments, the magnetic component 200 includes a plurality of lifting components 300, and the connecting component 220 includes a plurality of second abutment portions. The number of first abutment portions and second abutment portions is the same, and each second abutment portion is correspondingly disposed with one lifting component 300, that is, each second abutment portion is used to drive one lifting component 300. For example, the connecting component 220 includes two second abutment portions, which are respectively located at both ends of the connecting component 220; correspondingly, the lifting component 300 is provided with two (e.g., Figure 15 (As shown). The number of the second abutment and the number of the lifting parts 300 can also be greater than two, but examples are not detailed here.

[0171] When the connector 220 rotates, all the lifting members 300 move synchronously relative to the housing 100. In this way, multiple lifting members 300 can simultaneously push out the magnetically attached device, and the force on the magnetically attached device is more even, which makes it easier for the magnetic member 200 to push out the magnetically attached device more smoothly.

[0172] Please refer to Figure 16 and Figure 17 When multiple lifting members 300 are provided, the lifting members 300 can be arc-shaped, and the multiple lifting members 300 are arranged at intervals, all surrounding the magnetic member 200. In this case, the lifting members 300 are located on the periphery of the magnetic member 200, and the lifting end 320 is located on the periphery of the bearing surface 110. In this arrangement, the lifting members 300 can adapt to the annular magnetic member 200, avoiding it. Furthermore, this arrangement can increase the force-bearing area of ​​the magnetically attracted device during the ejection process and improve the uniformity of force on the magnetically attracted device.

[0173] In some other embodiments not shown, the magnetic element 200 may also include only one lifting element 300, which is annular. The annular lifting element 300 can also be adapted to the annular magnetic element 200, and it is beneficial to increase the force-bearing area of ​​the magnetically attracted device during the ejection process, as well as improve the uniformity of force on the magnetically attracted device.

[0174] Please see Figures 18 to 20 A second aspect of the present invention provides a magnetic connection device, comprising a first magnetic element 230, a second magnetic element 240, a housing 100, and a driving element 400. This magnetic connection device is designed for detachably attracting magnetically attachable devices, including but not limited to smartphones, tablets, and smartwatches. Specifically, both the first magnetic element 230 and the second magnetic element 240 are magnetic and capable of attracting magnetically attachable devices. The second magnetic element 240 is sleeved on the first magnetic element 230. (See also: [link to previous section]). Figures 18 to 20The 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 230 are spaced apart to ensure that there is no unnecessary physical interference or magnetic interference between them. In some embodiments, the first magnetic attractor 230 can be configured as a ring, and the second magnetic attractor 240 can be designed as a ring or a cylinder. The first magnetic attractor 230 can be composed of multiple magnet segments, and similarly, the second magnetic attractor 240 can also be composed of multiple magnet segments. In other embodiments, both the first magnetic attractor 230 and the second magnetic attractor 240 can be composed of a single complete ring-shaped magnet to ensure the stability and reliability of the magnetic connection.

[0175] Please see Figures 18 to 20 The housing 100 has a cavity 140 extending along a first direction X, the cavity 140 having a first opening and a second opening in the first direction X. A first magnetic attractor 230 is mounted on the side of the housing 100 near the first opening, thereby enabling effective contact and attraction with magnetically attractable devices. The drive member 400 consists of a rotating part 360 and a lifting part 350. The rotating part 360 is rotatably connected to the housing 100 and protrudes from the second opening, thereby facilitating user operation of the rotating part 360. The lifting part 350 is connected to the rotating part 360 by a threaded connection, and a second magnetic attractor 240 is mounted on the side of the lifting part 350 opposite to the rotating part 360.

[0176] The rotating part 360 is configured to rotate relative to the housing 100, so that the lifting part 350 moves relative to the housing 100 along the first direction X. When the second magnetic member 240 is in the second position, the side wall of the second magnetic member 240 away from the lifting part 350 protrudes from the side wall of the first magnetic member 230 away from the second opening. When the second magnetic member 240 is in the first position, the side wall of the second magnetic member 240 away from the lifting part 350 is flush with the side wall of the first magnetic member 230 away from the second opening. Thus, by rotating the rotating part 360, the lifting part 350 can drive the second magnetic member 240 to move along the first direction X, so that the second magnetic member 240 switches between the first position and the second position, thereby enabling the magnetically attracted device to separate or attract with the first magnetic member 230, achieving the purpose of adjusting the magnetic attraction force and ensuring the stable attraction and separation of the magnetically attracted device.

[0177] Specifically, by rotating the rotating part 360, the lifting part 350 can move relative to the housing 100 along the first direction X, thereby adjusting the position of the second magnetic member 240, moving it away from or closer to the first magnetic member 230. When the second magnetic member 240 moves away from the first magnetic member 230, it protrudes from the first magnetic member 230, weakening the magnetic attraction of the magnetic connection device to the magnetically attachable device, facilitating easy separation of the magnetically attachable device. Furthermore, during the separation process between the first magnetic member 230 and the magnetically attachable device, the second magnetic member 240 provides an attractive force to the magnetically attachable device, preventing it from accidentally falling and being damaged after separation from the first magnetic member 230, thus improving the safety of the magnetic connection device. When the second magnetic member 240 is close to the first magnetic member 230 and flush with it, the magnetic connection device provides sufficient attractive force to ensure a secure connection of the magnetically attachable device.

[0178] Please refer to 18 to Figure 20 To reduce the size of the magnetic connection device in the first direction X, in some embodiments, a cavity 471 is provided on the side of the rotating part 360 facing the first opening. This cavity 471 contains a first threaded structure 472 extending towards the lifting part 350. Furthermore, a second threaded structure 481 corresponding to the first threaded structure 472 is provided on the side of the lifting part 350 facing the second opening. The second threaded structure 481 can be inserted into the cavity 471 and threadedly connected to the first threaded structure 472. This design not only ensures precise control of the forward or backward movement of the lifting part 350 when the rotating part 360 rotates, but also increases the stability of the entire drive component 400. To improve durability, lubricating material can be added between the first threaded structure 472 and the second threaded structure 481 to reduce frictional loss and extend service life. In addition, a self-locking thread design can be used to prevent the rotating part 360 from loosening on its own without external force, ensuring the stability of the magnetic connection device.

[0179] Please see Figures 18 to 20The magnetic connection device also includes a first fixing member 840 and a second fixing member 850. The first fixing member 840 is connected to the side of the lifting part 350 facing away from the second opening. The side of the second magnetic suction member 240 facing the second opening is connected to the lifting part 350, and the side of the second magnetic suction member 240 facing away from the first magnetic suction member 230 is connected to the side of the first fixing member 840 facing the first magnetic suction member 230. This ensures a stable connection between the second magnetic suction member 240 and the lifting part 350, preventing movement or detachment of the second magnetic suction member 240 during the movement of the lifting part 350. Furthermore, the second fixing member 850 is connected to the side of the second magnetic suction member 240 facing away from the lifting part 350, and the side of the second fixing member 850 facing away from the first magnetic suction member 230 is also connected to the first fixing member 840, further ensuring the reliability of the fixation of the second magnetic suction member 240. In other words, the arrangement of the lifting part 350 and the second fixing member 850 effectively restricts the movement of the second magnetic member 240 along the first direction X, thereby maintaining the stability and functionality of the overall device.

[0180] Understandably, after the second magnetic chuck 240 is connected to the lifting part 350 and the first fixing part 840, the second fixing part 850 covers the side of the second magnetic chuck 240 opposite to the lifting part 350, and one end of the second fixing part 850 along the second direction Y is connected to the first fixing part 840. This not only enhances the fixing effect of the second magnetic chuck 240, but also facilitates the assembly of the second magnetic chuck 240. It should be noted that the second fixing part 850 and the first fixing part 840 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.

[0181] Please see Figures 18 to 20 In some embodiments, the first fixing member 840 and the second fixing member 850 are manufactured independently and then assembled. The first fixing member 840 has a clearance groove 841 on the side facing the second magnetic member 240 and away from the second opening. This clearance groove 841 design allows the second magnetic member 240 to be smoothly inserted between the first magnetic member 230 and the first fixing member 840, improving the ease of installation of the second magnetic member 240 and reducing friction and collision between the second magnetic member 240 and the first fixing member 840 during installation. Furthermore, the clearance groove 841 can also accommodate the end of the second fixing member 850 away from the first magnetic member 230. Specifically, one end of the second fixing member 850 can be completely embedded in the clearance groove 841, thereby ensuring the compactness and flatness of the entire device. In this way, the side wall of the second fixing member 850 away from the second magnetic member 240 can be kept flush with the side wall of the first fixing member 840 away from the second opening, which not only enhances the overall aesthetics of the appearance, but also avoids potential safety hazards or operational inconvenience caused by protruding parts.

[0182] Reference Figures 21 to 24 The magnetic accessory in the third aspect embodiment of the present invention includes: a housing 100, a lifting member 300, a magnetic member 200, and a driving member 400. The outer surface of the housing 100 includes a bearing surface 110. The magnetic member 200 is fixed inside the housing 100. The lifting member 300 is movably connected to the housing 100 and can switch between a second position and a first position. When the lifting member 300 is in the second position, the lifting member 300 protrudes relative to the bearing surface 110, and the protrusion distance of the lifting member 300 is a first distance. When the lifting member 300 is in the first position, the lifting member 300 protrudes, is flush with, or is recessed relative to the bearing surface 110. When the lifting member 300 protrudes relative to the bearing surface 110, the protrusion distance of the lifting member 300 is a second distance, and the first distance is greater than the second distance. The driving member 400 includes a button 490, which is slidably connected to the housing 100. The button 490 abuts against the lifting member 300 and can drive the lifting member 300 to move. The magnetic accessory can be fixed to the magnetically attachable device, and together with the magnetically attachable device, it can be attracted to other workpieces via the magnetic component 200. The magnetic accessory can also be fixed to other workpieces such as magnetic connecting devices, and the magnetically attachable device can be attracted to the magnetic accessory via the magnetic component 200. The magnetic accessory can also be attracted to both the magnetically attachable device and other workpieces such as magnetic connecting devices via the magnetic component 200. Taking the example of the magnetic accessory being fixed to the magnetically attachable device and together with the magnetically attachable device being attracted to other workpieces via the magnetic component 200, the housing 100 is fixed relative to the magnetically attachable device, and the bearing surface 110 on the outer surface of the housing 100 faces the magnet, where the magnet is the magnetic connecting device or other workpiece, and a magnetic attraction force can be generated between the magnetic component 200 and the magnet. When it is necessary to fix the magnetic device to the magnet, the lifting member 300 is driven to the first position. At this time, the magnet can be attached to, abut against, or closer to the bearing surface 110. The magnetic force between the magnet and the magnetic component 200 will increase, making the connection with the magnet more secure. When it is necessary to remove the magnetic accessory from the magnet, if the two are separated directly, the large magnetic force between them will cause a large pulling force on the magnet, which may cause deformation or displacement of the magnetic component 200. Therefore, when it is necessary to remove the magnetic accessory from the magnet, the lifting member 300 is moved by pressing the button 490, thereby switching the lifting member 300 to the second position. When the lifting member 300 is switched to the second position, the magnet will move away from the bearing surface 110 under the abutment of the lifting member 300, thereby reducing the magnetic force between the magnetic component 200 and the magnet, making it easier to separate the magnet and the magnetic accessory.

[0183] Reference Figures 21 to 24In this embodiment, when the lifting member 300 is in the first position, it can protrude, be flush with, or be recessed relative to the bearing surface 110. In one embodiment, when the lifting member 300 is in the first position protruding relative to the bearing surface 110, the magnet abuts against the lifting member 300 regardless of whether it is in the first or second position. In another embodiment, when the lifting member 300 is in the first position flush with or recessed relative to the bearing surface 110, the magnet abuts against the bearing surface 110 only in the second position. When the lifting member 300 is in the first position flush with or recessed relative to the bearing surface 110, the magnet can have a shorter distance from the magnetic component 200, resulting in a greater magnetic attraction between them and a stronger magnetic connection between the magnet and the magnetic component.

[0184] Reference Figures 21 to 24 According to some embodiments of the present invention, the driving member 400 includes two buttons 490, which are spaced apart along a second direction, which is the sliding direction of the buttons 490. Specifically, the two buttons 490 are arranged symmetrically. When pressing the two buttons 490, they can be pressed from two different directions, bringing them closer together. At this point, the resultant force on the entire magnetic accessory is zero, thus preventing the magnetic accessory from sliding. Furthermore, with two buttons 490, the lifting member 300 can be driven from more positions, making it easier to switch between the second and first positions. It also prevents the lifting member 300 from being squeezed against the housing 100 during sliding, thus avoiding jamming between the lifting member and the housing.

[0185] Reference Figures 21 to 24 According to some embodiments of the present invention, the button 490 includes a first inclined surface, and the lifting member 300 includes a second inclined surface, with the first inclined surface and the second inclined surface abutting against each other. To make the movement of the button 490 driving the lifting member 300 smoother and more stable, a first inclined surface is provided on the button 490 and a second inclined surface is provided on the lifting member 300. The abutting between the first and second inclined surfaces makes the fit between the button 490 and the lifting member 300 more stable.

[0186] Reference Figures 21 to 24According to some embodiments of the present invention, the driving member 400 further includes a synchronizing gear and two racks. Each button 490 is fixed to one rack. The synchronizing gear is rotatably connected to the housing 100. Both racks mesh with the synchronizing gear so that the two buttons 490 can move synchronously away from or towards each other. To ensure synchronized sliding of the lifting member 300 at various positions during sliding, the two buttons 490 need to slide synchronously when driving the lifting member 300. Therefore, a synchronizing gear and racks are provided so that the two buttons 490 can slide synchronously. Specifically, the two buttons 490 are respectively located on the left and right sides of the synchronizing gear, and the two racks on the two buttons 490 are respectively located on the upper and lower sides of the synchronizing gear, with the teeth of the two racks facing each other, so that the two buttons 490 can move synchronously towards or away from each other.

[0187] Reference Figures 21 to 24 According to some embodiments of the present invention, the magnetic accessory further includes a return spring, with two buttons 490 respectively disposed at both ends of the return spring. The return spring is used to drive the two buttons 490 away from each other. After the return spring is provided, when the buttons 490 are not pressed externally, the return spring causes the two buttons 490 to move away from each other. At this time, the buttons 490 will not drive the lifting member 300 to rise, and the lifting member 300 can slide to the first position by gravity, squeezing force, etc.

[0188] According to some embodiments of the present invention, the magnetic accessory further includes a magnetically oriented device housing, which is fitted onto the magnetically oriented device. The housing 100 is fixedly disposed on the side of the magnetically oriented device housing facing away from the magnetically oriented device. Through the fixed connection between the magnetically oriented device housing and the housing 100 of the magnetic accessory, wherein the fixed connection can be achieved by means of adhesive bonding or snap-fitting, and by using the magnetically oriented device housing to fix the connection to the magnetically oriented device, not only is the connection more stable, but it also provides better protection for the magnetically oriented device.

[0189] According to some embodiments of the present invention, the sliding direction of the button 490 is the width direction of the magnetically attached device housing, and the button 490 extends beyond the edge of the magnetically attached device housing along the sliding direction. When removing the magnetically attached device, the button 490 can be pressed conveniently by holding the side of the magnetically attached device in the width direction, thereby making it more convenient to remove the magnetically attached device from the magnetic component 200, and making it easier to separate the magnetically attached accessory from the magnetic component 200.

[0190] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
