[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0045] Without altering the maximum magnetic force of the magnetic holder, to make it easier for users to detach magnetically attached devices from the holder, related technologies have incorporated electromagnets into the magnetic holder. The magnetic force can be adjusted by controlling the on / off state or the magnitude of the current flowing through the electromagnet. However, this adjustment method does not fully utilize the characteristics of the electromagnet, resulting in a less than ideal user experience.

[0046] Specifically, if the magnetic force is adjusted by controlling the on / off state of the electromagnet, the electromagnet will not have a fixing effect when it is turned off, and the magnetically attached device will be at risk of falling. If the magnetic force is adjusted by adjusting the current of the electromagnet, the adjustment parameters required will be different for different magnetically attached devices or different usage scenarios, which makes the design of magnetically attached devices complicated and the user experience poor.

[0047] In view of this, see Figures 1-6This utility model provides a magnetic connection device 100, which can be used to magnetically fix any type of magnetically attachable device 200. The magnetically attachable device 200 itself may be magnetic, or it may be magnetically attached by assembling magnetic accessories. Specifically, the magnetically attachable device 200 may be a mobile phone or a tablet computer. The magnetic connection device 100 can fix the magnetically attachable device 200 solely by magnetic attraction, or it can work in conjunction with other forces (such as supporting force, clamping force, etc.) to fix the magnetically attachable device 200. Depending on the actual application scenario, the magnetic connection device 100 can be fixed in different ways. For example, in a desktop environment, the magnetic connection device 100 can be placed directly on the desktop; in a vehicle environment, the magnetic connection device 100 can be fixed to the vehicle through its own clamping mechanism or magnetic attraction mechanism; in addition, the magnetic connection device 100 can also be held directly or indirectly by the user. In this case, the magnetic connection device 100 can be a bracket accessory for connecting to the back of a mobile phone, or used for fixing a selfie stick to a mobile phone. Furthermore, unless otherwise specified, the relative orientational reference relationship between the magnetic connection device 100 (including any part) and the magnetically attracted device 200 described in this utility model refers to the positional relationship under a specific posture after the magnetic connection device 100 magnetically attracts and fixes the magnetically attracted device 200.

[0048] For details, see Figures 1-6 The magnetic connection device 100 includes a housing assembly 110 and a magnetic assembly 120. The housing assembly 110 has a cavity 111 and a magnetic surface 112. The magnetic surface 112 is adapted to support the magnetically attracted device 200. The direction perpendicular to the magnetic surface 112 is defined as the first direction X. The magnetic surface 112 is located on one side of the cavity 111 along the first direction X. The cavity 111 is the inner cavity of the housing assembly 110 itself, and the magnetic surface 112 is the outer wall surface of one side of the housing assembly 110.

[0049] See Figure 4 The magnetic component 120 is located in the cavity 111 and provides a magnetic force to attract the magnetically attachable device 200. Combined with the previous configuration of the housing component 110, when the user needs to magnetically fix the magnetically attachable device 200, the device 200 can be placed on the magnetic surface 112. Under the magnetic force of the magnetic component 120, the device 200 adheres to the magnetic surface 112, thus fixing the device 200 to the magnetic connection device 100. It should be noted that the attachment described in this invention requires excluding the influence of errors and microscopic gaps.

[0050] Specifically, see Figures 1-2The magnetic component 120 has a first state and a second state. In the first state, the magnetic component 120 is adapted to generate a magnetic attraction force on the magnetically attachable device 200 from the magnetic surface 112 towards the magnetic component 120. In the second state, the magnetic component 120 is adapted to generate a repulsive force on the magnetically attachable device 200 from the magnetic surface 112 towards the magnetic surface 112. It can be understood that in the first state, through the magnetic attraction force, the magnetic component can cause the magnetically attachable device 200 to adhere to the magnetic surface 112, thus providing stable support and fixing of the magnetically attachable device 200. In the second state, through the repulsive force, at least part of the magnetically attachable device 200 can be removed from the magnetic surface 112, while simultaneously weakening or eliminating the magnetic attraction force, making it easier for the user to remove the magnetically attachable device 200. Furthermore, after the repulsive force acts on the magnetically attachable device 200, a gap can exist between the magnetically attachable device 200 and the magnetic surface 112, which facilitates the user's gripping of the magnetically attachable device 200.

[0051] As can be seen, the magnetic connection device 100 of this utility model includes a housing assembly 110 and a magnetic assembly 120. The housing assembly 110 has a cavity 111 and a magnetic surface 112. The magnetic surface 112 is adapted to support the magnetically oriented device 200. The direction perpendicular to the magnetic surface 112 is a first direction X, and the magnetic surface 112 is located on one side of the cavity 111 along the first direction X. The magnetic assembly 120 is located in the cavity 111 and has a first state and a second state. In the first state, the magnetic assembly 120 is adapted to generate a magnetic attraction force on the magnetically oriented device 200 from the magnetic surface 112 towards the magnetic assembly 120. In the second state, the magnetic assembly 120 is adapted to generate a repulsive force on the magnetically oriented device 200 from the magnetic surface 112 towards the magnetic surface 112. After the magnetic assembly 120 switches from the first state to the second state, the connection assembly 130 is adapted to fixably connect the magnetically oriented device 200. Compared to related technologies that adjust magnetic force by controlling the on / off state or current magnitude of the electromagnet 121, this invention, while utilizing the repulsive force of the magnetic components to make removal easier for the user, further avoids instability caused by the switching of the magnetic components' states through the connection component 130. Therefore, the magnetic connection device 100 of this invention allows users to more easily remove the magnetically attached device 200, while maintaining a good fixation effect.

[0052] To secure the magnetically attached device 200 in the second state and prevent it from falling, in some embodiments, the magnetic connection device 100 further includes a connecting component 130. After the magnetic component 120 switches from the first state to the second state, the connecting component 130 is adapted to securely connect the magnetically attached device 200. The connecting component 130 can securely connect the magnetically attached device 200 using any type of detachable connection method, such as magnetic connection, clamping connection, etc. Furthermore, the state in which the connecting component 130 securely connects the magnetically attached device 200 can be formed in the first state or when switching from the first state to the second state. Therefore, while the repulsive force of the magnetic component makes it easier for the user to remove the device, the connecting component 130 further avoids the problem of unstable fixation caused by the state switching of the magnetic component. The following description uses embodiments where the magnetic connection device 100 includes the connecting component 130 as examples.

[0053] For the setting of the switching state of magnetic component 120, please refer to... Figures 1-6 In some embodiments, the magnetic component 120 includes a magnet 121, a switch 122, and a power source. The magnet 121 is electrically connected to the switch 122, and the switch 122 is electrically connected to the power source, so that the switch 122 can control the magnetic component 120 to switch between a first state and a second state. The switch 122 can take any form; for example, the user can control the switch 122 by tossing or pressing it. The switch 122 can have multiple positions, each corresponding to a different magnitude of repulsive force. It is understood that the user can adjust the energization state of the magnet 121 by controlling the switch 122, thereby controlling the magnetic component 120 to switch between the first and second states.

[0054] For the fixed connection settings of connection component 130, see [link to documentation]. Figures 1-6In some embodiments, the magnetic component 120 and the connecting component 130 are arranged opposite each other along a second direction Y perpendicular to the first direction X. A third direction Z is perpendicular to both the first direction X and the second direction Y. The connecting component 130 is rotatably connected to the housing component 110, and its rotation axis is parallel to the third direction Z, so that after the magnetic component 120 switches from the first state to the second state, the connecting component 130 rotates relative to the housing component 110. It is understood that through this rotatable connection, when a repulsive force is applied to the magnetically attracted device 200, the connecting component 130 can rotate around the same rotation axis as the magnetically attracted device 200. This arrangement allows the connecting component 130 to maintain a fixed connection to the magnetically attracted device 200 while adapting to the repulsive force, resulting in a better fixing effect. More specifically, in some embodiments, the housing component 110 includes a base 113 for placing the magnetic connecting device 100 on a plane. Along the second direction Y, the base 113, the magnetic component 120, and the connecting component 130 are arranged opposite each other in sequence. It is understandable that the base 113 is located on the lower side of the magnetic connection device 100 and provides support for the entire magnetic connection device 100 when it is placed. At the same time, after the base 113, the magnetic component 120 and the connecting component 130 are arranged in sequence, the rotation axis of the connecting component 130 is located on the side of the connecting component 130 away from the magnetic component 120 along the second direction Y. After the repulsive force is applied to the magnetically attracted device 200, the lower side of the magnetically attracted device 200 and the magnetic surface 112 are separated, making it easier for the user to remove the magnetically attracted device 200.

[0055] Based on the previous fixed connection setup of connection component 130, see [link to previous documentation]. Figure 5 In some embodiments, the housing assembly 110 includes a limiting structure 114, and the connecting assembly 130 includes an abutment structure 131. Both the limiting structure 114 and the abutment structure 131 are located in the cavity 111. During the rotation of the connecting assembly 130 around the rotation axis, the abutment structure 131 can abut against the limiting structure 114, allowing the connecting assembly 130 to rotate to its limit position. Through the cooperative arrangement of the limiting structure 114 and the abutment structure 131, the maximum distance of rotation of the connecting assembly 130 relative to the housing assembly 110 can be limited by their abutment action, thereby making the magnetic connecting device 100 easier to use. Both the limiting structure 114 and the abutment structure 131 can be located at any suitable position. Specifically, in… Figure 5In the illustrated embodiment, the limiting structure 114 is located on the side of the wall where the magnetic surface 112 is located, facing the cavity 111. The connecting component 130 can magnetically support the magnetically absorbing device 200. The abutting structure 131 is located on the side of the wall of the connecting component 130 that is suitable for magnetically absorbing the magnetically absorbing device 200, facing the cavity 111. When viewed along the second direction Y, the limiting structure 114 has a protruding structure, and the abutting structure 131 has an "L" shaped structure, and the lower end of the "L" shape can abut against the limiting structure 114.

[0056] See Figures 1-6 In some embodiments, the magnetic connection device 100 further includes a rotating shaft 140 and a reset member 150. The rotating shaft 140 passes through the housing assembly 110 and the connecting assembly 130. Along the second direction Y, the reset member 150 and the rotating shaft 140 are respectively connected to both ends of the connecting assembly 130. In a first state, the reset member 150 is configured to generate a force on the connecting assembly 130 from the magnetic attraction surface 112 towards the magnetic assembly 120. By providing the reset member 150, after the repulsive force acts on the magnetically attracted device 200 and the connecting assembly 130, the reset member 150 can restore the connecting assembly 130 to its initial position when it is not subjected to the repulsive force. Specifically, in some embodiments, the reset member 150 can magnetically attract the connecting assembly 130 to the housing assembly 110. The magnetic attraction force generated by the reset member 150 can be set to be relatively small (at least less than the repulsive force), so that while stabilizing the connecting assembly 130 in its initial position, it will not affect the rotation of the connecting assembly 130 after being subjected to the repulsive force. In other embodiments, the force generated by the reset member 150 can be an elastic force, and can achieve the same effect as the magnetically attracted reset member 150 in the above embodiments. Furthermore, in some embodiments, a damper is fitted on the outer side of the rotating shaft 140, the damper being used to achieve a smoother and more stable rotational movement of the connecting assembly 130.

[0057] For the specific settings of the connection component 130 for fixing the magnetically attached device 200, see [link to documentation]. Figures 1-6In some embodiments, the connecting component 130 includes a permanent magnet 132. After the magnetic component 120 switches from a first state to a second state, the permanent magnet 132 is adapted to magnetically attract the magnetically attractable device 200, so that the connecting component 130 is adapted to fixarily connect to the magnetically attractable device 200. It should be noted that in some embodiments, the connecting component 130 also includes a connecting body, which is movably connected to the housing component 110, and the permanent magnet 132 is independent of the connecting component 130 and located inside the connecting component 130; in other embodiments, at least a portion of the connecting component 130 is made of permanent magnet 132. Further, in some embodiments, the magnetic component 120 includes a magnet 121, which extends in a semi-circular shape and forms a first notch 123, and the permanent magnet 132 extends in a semi-circular shape and forms a second notch 133. Along the second direction Y, the first notch 123 and the second notch 133 are arranged opposite to each other and face opposite directions. Through the above arrangement, the magnet 121 and the permanent magnet 132 can work together to achieve a good magnetic attraction effect. It should be noted that, in the description of this utility model, the circumferential extension and the ring-shaped structure do not limit the shape of the extension trajectory to a circular ring. Therefore, the extension trajectory under this limitation can also be a rectangular ring, an elliptical ring, or any other ring shape. Specifically, in some embodiments, when viewed along the first direction X, the magnet 121 and the permanent magnet 132 are both semi-circular rings of the same (or similar) size, and together they form a ring-shaped structure to adapt to the magnetic design of the magnetically attracted device 200 (e.g., the Magesafe magnetic ring adapted to Apple mobile phones).

[0058] See Figures 1-6 In some embodiments, the housing assembly 110 is adapted to have a mounting groove 115 on the side facing the magnetically attachable device 200, and the connecting assembly 130 is located in the mounting groove 115. In a first state, along the first direction X, the connecting assembly 130 is adapted to be parallel to the magnetic surface 112 on the side facing the magnetically attachable device 200. It can be understood that the housing assembly 110 is recessed along the first direction X on the side facing the magnetically attachable device 200 and defines the mounting groove 115. The arrangement of the connecting assembly 130 in the mounting groove 115 and parallel to the magnetic surface 112 can make reasonable use of the space of the housing assembly 110, making it easier for the connecting assembly 130 and the magnetic surface 112 to jointly support and fix the magnetically attachable device 200, and making the magnetic connection device 100 more aesthetically pleasing.

[0059] A second aspect of this utility model also provides an electronic device holder, which includes the magnetic connection device 100 of any of the above embodiments. Besides supporting the electronic device, the electronic device holder can also have other functions. Therefore, taking a mobile phone as an example, the electronic device holder can specifically be a mobile phone mounting bracket (for fixing on a desktop, vehicle, or any suitable scenario), a bracket accessory connecting to the back of the mobile phone, a magnetic power bank, a magnetic wireless charger, or a selfie stick. The magnetically attachable device 200 in this case includes any type of electronic device.

[0060] In some embodiments, the magnetic connection device 100 serves as the entirety of the electronic device bracket; in other embodiments, the electronic device bracket includes multiple components, and the magnetic connection device 100 may be one of these components. The multiple components may be mechanically connected to each other or spaced apart from each other. For example, when the magnetically attachable device 200 is a mobile phone and the electronic device bracket is a magnetic wireless charger, the magnetic connection device 100 serves as a module for fixing and supporting the mobile phone. The electronic device bracket also includes a charging module, which is electrically connected to the magnetic connection device 100, so that the electronic device bracket can supply power to the mobile phone while supporting it.

[0061] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the application concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
