[0051] Stands are commonly used to support magnetically attached devices such as mobile phones or tablets, increasing the flexibility of device usage scenarios. Among existing stands, magnetic stands are becoming increasingly widespread, especially in the field of magnetic mobile phone holders in vehicles, providing convenience for securing mobile phones and other electronic products. However, existing magnetic stands, in order to improve the stability of the phone's attachment, have a relatively large magnetic force, requiring users to apply considerable force to remove the phone, making it inconvenient to remove.

[0052] This invention provides a magnetic holder that can be used to magnetically attach a mobile phone to the holder, making it easier and less strenuous to remove the phone. For ease of description, unless otherwise specified, the convenient holder will be referred to as the holder below.

[0053] Reference Figure 1 , Figure 2 as well as Figures 4 to 10 , Figure 1 This is a schematic diagram of the structure of the magnetic holder according to the first embodiment of the present invention. Figure 2 for Figure 1 Exploded view Figure 4 for Figure 1 A diagram from another perspective. Figure 5 for Figure 4 Mid-section view, Figure 6 This is an enlarged view of region A in diagram 5.

Figure 4 and Figure 8 The first housing portion is not shown. The magnetic bracket in this embodiment includes a magnetic component 400 and a drive mechanism 200.

[0054] The magnetic component 400 includes a plurality of magnetic elements 410 (such as...) Figure 2As shown, the magnetic attachment assembly 400 is used to attract magnetically attached devices, such as mobile phones or tablets. For ease of explanation, the following embodiments use mobile phones as an example of magnetically attached devices. The mobile phone can be directly attached to the magnetic attachment assembly 400, or separated by other components. In the following embodiments, the bracket also includes a support member 100, which includes a support portion 140 with a support surface 141. The magnetic attachment assembly 400 is located on the side of the support portion 140 facing away from the support surface 141, thereby attracting the mobile phone to the support surface 141. The driving mechanism 200 includes an input end 201 and an output end 202. The input end 201 is used for the user to apply force, and the output end 202 is used to cause relative movement between the magnetic attachment assembly 400 and the magnetically attached device, thereby reducing the magnetic attraction between the magnetic attachment assembly 400 and the magnetically attached device. For example, the drive mechanism 200 includes a lifting member (not shown in the figure), which can abut against the surface of the mobile phone facing the magnetic assembly 400 and lift the mobile phone to increase the distance between the mobile phone and the magnetic assembly 400, thereby reducing the magnetic attraction force between the mobile phone and the magnetic assembly 400; or the magnetic bracket also includes a support member 100, which includes a support portion 140 with a support surface 141 for abutting against the magnetically attracted device to support the magnetically attracted device, and the magnetic assembly 400 is positioned... On the side of the support portion 140 facing away from the support surface 141; some or all of the plurality of magnetic members 410 are capable of moving relative to the support member 100. A magnetic member 410 capable of moving relative to the support member 100 is defined as the first magnetic member 411. The output end 202 is directly connected to or indirectly connected to the first magnetic member 411 through other rotating structures, used to drive the first magnetic member 411 to move (move or rotate) relative to the support member 100, thereby reducing the direct facing distance between the magnetically attracted members inside the phone and the magnetic assembly 400 (e.g., ...). Figure 6 and Figure 10 (As shown) or the area directly opposite, to reduce the magnetic force between the phone and the magnetic component 400. The magnetically attracted component inside the phone is, for example, a metal part that can be attracted magnetically, or a magnet, which can be an integral part of the phone or set on the phone case and fitted onto the phone.

[0055] The drive mechanism 200 is configured such that when the input end 201 is subjected to an external force F1, the output end 202 outputs a driving force F2, where F2 > F1. The drive mechanism 200 includes, for example, a reduction gear, a worm gear, or a lever, a force-saving structure. For instance, in some embodiments, the drive mechanism 200 includes a drive member 210, which is rotatably connected to the support member 100. The drive member 210 is provided with a lever structure (such as...). Figure 4As shown), one end of the driving member 210 includes an input portion 211, and the other end includes an output portion 212. Input end 201 includes an input portion 211, and output end 202 includes an output portion 212. Alternatively, in some embodiments, the driving mechanism 200 includes two driving members 210, which are rotatably connected to the support member 100, and the rotation axes of the two driving members 210 are arranged in parallel. Both driving members 210 are provided with lever structures. One end of the driving member 210 includes an input portion 211, and the other end includes an output portion 212. Input end 201 includes two input portions 211, and output end 202 includes two output portions 212. During use, by bringing the input portions 211 of the two driving members 210 together, the first magnetic suction member 411 can be driven to move (e.g., ...). Figure 7 As shown in the diagram, this reduces the magnetic attraction between the magnetic component 400 and the mobile phone. Specifically, the drive mechanism 200 in this embodiment is configured such that when the input end 201 is subjected to an external force F1, the output end 202 outputs a driving force F2, where F2 > F1. Therefore, when the convenient magnetic holder of this embodiment is used to support a mobile phone, during the process of the user removing the phone, a smaller force can be used to resist the magnetic attraction between the mobile phone and the magnetic component 400, causing relative movement between the magnetic component 400 and the mobile phone. This reduces the magnetic attraction between the mobile phone and the magnetic component 400, making it easier to remove the mobile phone and thus making the holder of this embodiment more convenient to use.

[0056] It should be noted that, as in the above embodiment, the driving member 210 reduces the magnetic attraction between the mobile phone and the magnetic component 400 by driving the first magnetic member 411 to move, without having to hold the mobile phone, thus avoiding the risk of the mobile phone being damaged by pressure.

[0057] Reference Figure 14 , Figure 14 This is a schematic diagram of the structure of a convenient magnetic holder according to the fourth embodiment of the present invention. The holder can be directly connected to a platform such as a vehicle or desktop. Alternatively, as in some embodiments, the holder also includes a base 700, which is, for example, a flat-bottomed column for direct placement on a platform such as a desktop. The base 700 can also be a suction cup or a clamp. For example, the holder is a vehicle-mounted holder. In use, the holder can be attached to glass using the suction cup or clamped to the grille of a ventilation opening using the clamp, thereby improving the stability of the magnetic holder installation. Furthermore, the connection between the base 700 and the support member 100 is a rotatable connection or a ball joint, allowing the support member 100 to be angled relative to the base 700. Therefore, users can adjust the angle of their phones to suit various usage needs, thus improving the practicality of the holder in this embodiment.

[0058] Reference Figures 5 to 10In some embodiments, the magnetic bracket further includes a mounting member 420, to which a first magnetic member 411 is connected. The mounting member 420 includes a first guide portion (the second connecting portion 422 in the following embodiment), and the support member 100 includes a second guide portion (the inner wall of the guide hole 121 in the following embodiment). The first guide portion and the second guide portion are slidably engaged along a first direction. The first guide portion and the second guide portion are, for example, a slider and a groove, or a guide rod and a guide hole 121. The first direction is perpendicular to the support surface 141. A driving member 210 is connected to the mounting member 420 and is capable of driving the mounting member 420 to move relative to the support member 100 along the first direction. For example, the output part 212 is rotatably connected to the mounting member 420. The rotation axis between the output part 212 and the mounting member 420 is parallel to the support surface 141. The rotation axis between the driving member 210 and the support member 100 is the first rotation axis, which is parallel to the support surface 141. That is, the driving member 210 can rotate in the thickness direction of the support member 100, so that the output part 212 can move in the thickness direction of the support member 100, thereby driving the mounting member 420 to move in the thickness direction of the support member 100 to adjust the distance between the mounting member 420 and the support surface 141, that is, to adjust the distance between the first magnetic member 411 and the mobile phone, thereby reducing the magnetic attraction between the bracket and the mobile phone, making the mobile phone easier to remove.

[0059] Alternatively, as in some embodiments, the first rotation axis is perpendicular to the support surface 141, and the mounting member 420 has a supporting portion 423 protruding toward the output portion 212, the supporting portion 423 having a first supporting surface 4231 (e.g. Figure 6 and Figure 10 As shown, the first abutting surface 4231 faces the support surface 141, and along the direction of the output portion 212 toward the abutting portion 423, the distance between the first abutting surface 4231 and the support surface 141 gradually decreases, and the output portion 212 can slide against the first abutting surface 4231, thereby causing the support member 100 to be subjected to a component force along the first direction, so that the mounting member 420 moves away from the support surface 141.

[0060] Similarly, in some embodiments, the output portion 212 has a second abutting surface (not shown in the figure), which faces away from the support surface 141. The mounting member 420 has an abutting portion 423 protruding towards the output portion 212. Along the direction from the output portion 212 towards the abutting portion 423, the distance between the second abutting surface and the support surface 141 gradually decreases. The output portion 212 can move towards the abutting portion 423 so that the second abutting surface slides against the abutting portion 423, thereby subjecting the abutting portion 423 to a component force facing away from the support surface 141, causing the mounting member 420 to move away from the support surface 141. When the phone needs to be attracted again, the phone is placed on the support surface 141, generating a magnetic attraction between it and the first magnetic member 411. This causes the mounting member 420 to move towards the support member 100, increasing the magnetic attraction between the phone and the magnetic assembly 400, thus firmly attracting the phone to the support surface 141.

[0061] It is known that the first rotation axis is perpendicular to the support surface 141, that is, the motion plane of the driving member 210 is parallel to the support surface 141. In this embodiment, it is only necessary to provide motion space for the driving member 210 in the direction parallel to the support member 100. The design of the support member 100 has the requirement of the size of the contact surface with the mobile phone. That is, the design requirement of providing space for the movement of the driving member 210 in this embodiment is consistent with the requirement of the size of the contact surface between the support member 100 and the mobile phone, and there is no need to increase the thickness of the support member 100 to provide motion space for the driving member 210.

[0062] Furthermore, referring to Figure 3 Based on the above embodiments, the support also includes a first elastic element 500, which is, for example, a compression spring, a tension spring, or an elastic rope, or any other elastic structure. One end of the first elastic element 500 is connected to the support member 100 (e.g., Figure 3 As shown, the first elastic member 500 is connected to the second housing portion 120, but is not limited thereto. The first elastic member 500 can also pass through the second housing portion and be connected to the first housing portion 110), and the other end is connected to the mounting member 420, so that the mounting member 420 is subjected to a force toward the support surface 141, so that the first magnetic member 411 can be more easily reset and adsorb the mobile phone.

[0063] In some embodiments, the mounting member 420 includes a third guide portion, and the support member 100 includes a fourth guide portion. The third guide portion and the fourth guide portion slide in a second direction, which is parallel to the support surface 141. The driving member 210 is connected to the mounting member 420 and can drive the mounting member 420 to move along the second direction. For example, the driving mechanism 200 includes two driving members 210, which are symmetrically arranged. Correspondingly, the magnetic suction assembly 400 includes two mounting members 420, and each driving member 210 is connected to one mounting member 420. Thus, during use, the user can bring the input portions 211 of the two driving members 210 together with their hands, thereby causing the two mounting members 420 to move back to back, so as to adjust the area of ​​the first magnetic suction member 411 mounted on the two mounting members 420 to be directly opposite the magnetic suction member inside the mobile phone, making the bracket of this embodiment more convenient to use.

[0064] Reference Figure 3 and Figure 4 , Figure 4 for Figure 1 Another schematic diagram from a different perspective shows that in some embodiments, the support member 100 includes a first shell portion 110, a second shell portion 120, and a third shell portion 130 (e.g., Figure 3 As shown), the second housing 120 is connected to the first housing 110 by means of snap-fit ​​or screw connection, and together they form the first mounting cavity 150. The driving member 210 includes a first connecting part 215. For example, the driving member 210 includes an input force arm 213, an output force arm 214, and the first connecting part 215 (as shown). Figure 4 As shown, both the input arm 213 and the output arm 214 are connected to the first connecting portion 215. The input arm 213 includes an input portion 211 and an output portion 212. One end of the driving member 210 is located inside the first mounting cavity 150, and the other end is located outside the first mounting cavity 150. The two ends of the first connecting portion 215 are respectively rotatably engaged with the first housing portion 110 and the second housing portion 120. The third housing portion 130 includes a support portion 140. The third housing portion 130 is connected to the side of the second housing portion 120 opposite to the first housing portion 110, and together they define the second mounting cavity 160. The magnetic suction member 410 is located inside the second mounting cavity 160. On the one hand, during installation, the drive member 210 can be snapped and fixed by connecting the first shell 110 and the second shell 120 without any other additional assembly steps, making the bracket installation of this embodiment simpler; on the other hand, the drive member 210 is located between the first shell 110 and the second shell 120, which can play a certain guiding role in the rotation of the drive member 210, so that the rotation of the drive member 210 is more stable and smooth, reducing the risk of the drive member 210 jamming, thereby improving the reliability of the bracket of this embodiment.

[0065] It should be noted that the first connecting part 215, the output force arm 214, and the input force arm 213 are, for example, an integral structure, or the output force arm 214 and the input force arm 213 are defined with connecting holes, and the first connecting part 215 is inserted into the connecting holes.

[0066] Furthermore, referring to Figure 6 and Figure 10 In some embodiments, the second shell portion 120 has a guide hole 121, the inner wall of which includes a second guide portion. The mounting member 420 includes a mounting portion 421, a second connecting portion 422, and a supporting portion 423. The first magnetic member 411 is mounted on the mounting portion 421. One end of the second connecting portion 422 is connected to the mounting portion 421, and the other end passes through the guide hole 121 and connects to the supporting portion 423. The second connecting portion 422 includes a first guide portion. Therefore, in this embodiment, no other structure is needed to form the first and second guide portions, making the bracket structure of this embodiment simpler and reducing processing costs.

[0067] Reference Figure 11 , Figure 11 This is a schematic diagram of the magnetic suction bracket according to a second embodiment of the present invention. In some embodiments, the driving member 210 includes an input force arm 213, an output force arm 214, and a first connecting part 215. The first connecting part 215 is rotatably connected to the support member 100. The input force arm 213 includes a first driving part 2131 and a second driving part 2132. The first driving part 2131 is connected to the first connecting part 215, and the second driving part 2132 includes an input part 211 and is movably connected to the first driving part 2131 to adjust the distance between the input part 211 and the first connecting part 215. The output force arm 214 includes an output part 212 and is connected to the first connecting part 215. Therefore, during use, the user can adjust the distance between the input part 211 and the first connecting part 215 according to their needs, that is, adjust the size of the input force arm in the lever, thereby adjusting the amplification factor of the output force F2. For example, a user with less strength can increase the distance between the input part 211 and the first connecting part 215 to increase the amplification factor of the output force F2. Users with greater strength can reduce the distance between the input section 211 and the first connecting section 215. This reduces the installation space of the bracket in this embodiment and makes the bracket more aesthetically pleasing. For example, in some embodiments, the first driving section 2131 has a first mounting hole, and the second driving section 2132 is inserted into the first mounting hole and can move axially relative to the first driving section 2131 along the mounting hole; or, as in some embodiments, the second driving section 2132 has a second mounting hole, and the first driving section 2131 is inserted into the second mounting hole and can move axially relative to the second driving section 2132 along the second mounting hole.

[0068] Similarly, in some embodiments, the first driving part 2131 is rotatably connected to the second driving part 2132, so that the first driving part 2131 can rotate toward the second driving part 2132 to adjust the distance between the input part 211 and the first connecting part 215. For example, in some embodiments, the rotation axis between the first driving part 2131 and the second driving part 2132 is a third rotation axis, which is perpendicular to the first rotation axis (the rotation axis between the driving member 210 and the support member 100). Thus, during use, the user can make different included angles between the first driving part 2131 and the second driving part 2132, thereby making different distances between the input part 211 and the first connecting part 215, thus improving the practicality of the bracket in this embodiment. Furthermore, since the third rotation axis is perpendicular to the first rotation axis, the position locking of the first driving part 2131 and the second driving part 2132 does not require a limiting structure, making the structure of the bracket in this embodiment simpler.

[0069] Reference Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the structure of the magnetic holder according to the third embodiment of the present invention. Figure 13 for Figure 12 A schematic diagram of another state of the magnetic bracket. In some embodiments, the support member 100 includes a first shell 110, a second shell 120, and a third shell 130. The second shell 120 is connected to the first shell 110 and together forms a first mounting cavity 150. The drive member 210 includes a first connecting portion 215. One end of the drive member 210 is located inside the first mounting cavity 150, and the other end is located outside the first mounting cavity 150. The two ends of the first connecting portion 215 are rotatably engaged with the first shell 110 and the second shell 120. The third shell 130 includes a support portion 140. The third shell 130 is connected to the side of the second shell 120 opposite to the first shell 110 and together defines a second mounting cavity 160. The magnetic member 410 is located inside the second mounting cavity 160. The first drive unit 2131 is rotatably connected to the second drive unit 2132. The rotation axis between the first connecting part 215 and the support member 100 is the first rotation axis, and the rotation axis between the first drive unit 2131 and the second drive unit 2132 is the second rotation axis. The second rotation axis is parallel to the first rotation axis, and the first drive unit 2131 also includes a limiting structure to limit the maximum rotation angle of the second rotation axis. The shape of the second drive unit 2132 is adapted to the outer wall of the support member 100, so that the second drive unit 2132 can rotate toward the support member 100 and fit against the outer wall of the support member 100.

[0070] Specifically, when the driving component 210 is not required, the first driving part 2131 is attached to the outer surface of the support component 100, making the bracket more concise and aesthetically pleasing. For example, if the support component 100 has an arc-shaped structure and the first driving part 2131 is also arc-shaped, the first driving part 2131 can be attached to the outer wall of the support component 100 when not in use. Alternatively, if the support component 100 has a square structure, the first driving part 2131 includes a vertically arranged first segment and a second segment. The first segment is rotatably connected to the second driving part 2132, and the end face of the second driving part 2132 is flush with the outer wall of the support component 100. This allows the first driving part 2131 to be attached to the outer wall of the support component 100, and the corner of the first driving part 2131 to be located at the corner of the support component 100. Furthermore, when the first magnetic suction member 411 needs to be driven by the driving member 210, after the first driving part 2131 rotates at a certain angle relative to the second driving part 2132, the first connecting end can abut against the end face of the first driving part 2131, thereby restricting the rotation of the second driving part 2132. That is, the first segment includes the first limiting part 21311, without the need to set up additional structures, making the structure of the driving member 210 in this embodiment simpler.

[0071] In some embodiments, the magnetic holder further includes a clamping mechanism 300, which includes a first clamping member 310 and a second clamping member 320. The first clamping member 310 and the second clamping member 320 are disposed opposite to each other, and at least one is movably connected to the support member 100. Both the first clamping member 310 and the second clamping member 320 protrude from the support surface 141 and are used to clamp magnetically attracted devices. A driving mechanism 200 is connected to the clamping mechanism 300 and can drive the first clamping member 310 and the second clamping member 320 to move relative to each other. For example, the driving mechanism 200 includes two driving members 210, which are respectively connected to the first clamping member 310 and the second clamping member 320. Thus, while driving the first magnetic attracting member 411 to move through the driving members 210, the first clamping member 310 and the second clamping member 320 can be driven to move away from each other and open without additional operation, making the holder of this embodiment more convenient to use. Specifically, this embodiment further includes a clamping mechanism 300 on the basis of the magnetic suction component 400, which makes the mobile phone of this embodiment more secure. As a result, the maximum magnetic attraction between the magnetic suction component 400 and the mobile phone can be adaptively reduced, so the mobile phone can be removed more easily when the first clamping member 310 and the second clamping member 320 are opened.

[0072] Furthermore, based on the above embodiments, the bracket also includes a second elastic member 600. The second elastic member 600 is used to subject the first clamping member 310 and the second clamping member 320 to forces that move towards each other, so that the first clamping member 310 and the second clamping member 320 clamp the mobile phone. Exemplarily, the second elastic member 600 is a tension spring or elastic rope, or other elastic structure that stores tension energy. The two ends of the first elastic member 500 are respectively connected to the first clamping member 310 and the second clamping member 320, so that the first clamping member 310 and the second elastic member 600 are subjected to tensile forces that move towards each other. As another example, the second elastic element 600 is a compression spring or a spring sheet compression energy storage elastic structure. The bracket includes two second elastic elements 600. One end of one second elastic element 600 is connected to the first clamping member 310 and the other end is connected to the support member 100, so that the first clamping member 310 is subjected to a pushing force toward the second clamping member 320. One end of the other second elastic element 600 is connected to the second clamping member 320 and the other end is connected to the support member 100, so that the second clamping member 320 is subjected to a pushing force toward the first clamping member 310.
