Description

Technical Field

[0001] The present application relates to the field of support connection technology, and in particular to a magnetic connection device and an electronic equipment bracket. Background Art

[0002] Magnetic attachment devices are used to secure electronic devices, allowing users to use them at a comfortable and effortless angle. These devices include magnetic components, whose magnetic attraction secures the electronic device to the device. To ensure a secure attachment of the electronic device, magnetic components with strong attraction are typically used.

[0003] However, this requires a lot of force to remove the electronic device from the magnetic connection device, which leads to a poor user experience. Magnetic parts with smaller magnetic attraction forces may also have problems with weak adhesion. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a magnetic connection device and an electronic device bracket that change the magnitude of the magnetic attraction by changing the distance between the magnetic member and the electronic device.

[0005] The present application provides a magnetic connection device, comprising: a fixed shell having a storage space, the fixed shell including a first wall capable of supporting an electronic device; a lifting assembly at least partially located in the storage space; a first magnetic member located in the storage space and arranged on a side of the lifting assembly close to the first wall, for providing a magnetic attraction force for adsorbing the electronic device; a second magnetic member arranged on the first wall, for providing a magnetic attraction force for adsorbing the electronic device; wherein the lifting assembly is configured to drive the first magnetic member to move closer to or away from the first wall.

[0006] In the technical solution of the embodiments of the present application, because the lifting assembly is configured to move the first magnetic member toward or away from the first wall, the distance between the first magnetic member and the first wall can be changed, thereby increasing or decreasing the magnetic attraction of the first magnetic member to the electronic device located on the first wall. Since the second magnetic member is provided on the first wall, regardless of how the magnetic attraction provided by the first magnetic member changes, the second magnetic member can still provide a certain magnetic attraction to hold the electronic device, helping to prevent the electronic device from falling due to a sudden decrease in the magnetic attraction of the first magnetic member during user adjustment. When the first magnetic member is close to the first wall, the first and second magnetic members work together to provide a stronger magnetic attraction, making the magnetic connection device suitable for securing heavier electronic devices and improving the secure attachment. When the magnetic member moves away from the first wall, the magnetic attraction decreases, allowing the user to easily pick up the electronic device. Because the lifting assembly is at least partially located in the storage space and the magnetic member is also located in the storage space, the fixed housing can protect and accommodate the first magnetic member and at least a portion of the lifting assembly.

[0007] In some embodiments, the magnetic connection device also includes a bottom cover connected to the fixed shell, the bottom cover and the first wall are opposite to each other along the first direction, the lifting assembly includes an adjusting member and a lifting member, one side of the lifting member is connected to the first magnetic member, and the other side of the lifting member passes through the fixed shell and is arranged on the bottom cover in a manner that can slide along the first direction, the adjusting member is located between the bottom cover and the fixed shell, the adjusting member surrounds the lifting member and is connected to the lifting member through a threaded structure, the threaded structure includes a spiral groove arranged with the first direction as the axis and a spiral protrusion inserted in the spiral groove, one of the spiral groove and the spiral protrusion is arranged on the adjusting member, and the other of the spiral groove and the spiral protrusion is arranged on the lifting member.

[0008] Thus, by rotating the adjusting member, the thread in the adjusting member can push the lifting member to move along the first direction, so that the lifting member can drive the first magnetic member to move closer to or away from the first wall, thereby achieving adjustment of the magnetic attraction force.

[0009] In some embodiments, the fixed shell is constructed with a limit column protruding toward the adjusting member on one side facing the adjusting member, and the adjusting member is provided with a limit groove whose extension direction is perpendicular to the first direction. The limit column is inserted into the limit groove and can slide along the limit groove, and is used to limit the rotation angle of the adjusting member through the cooperation of the limit column and the limit groove.

[0010] Thus, the adjusting member can rotate in one direction to a position where the groove wall on one side of the limiting groove contacts the limiting column and is limited by the limiting column, and the adjusting member can rotate in another direction to a position where the groove wall on the other side of the limiting groove contacts the limiting column and is limited by the limiting column, thereby limiting the rotation angle of the adjusting member.

[0011] In some embodiments, the limiting post passes through the limiting slot and is connected to the bottom cover.

[0012] Thus, the fixed shell is connected to the bottom cover through the limiting column.

[0013] In some embodiments, the magnetic connection device also includes a limit plate, the lifting member is connected to the limit plate on the side close to the bottom cover, a limit cavity is constructed between the adjusting member and the bottom cover, and the limit plate is located in the limit cavity, wherein the limit plate can move between the two side walls of the limit cavity in the first direction to limit the movement range of the lifting member along the first direction.

[0014] Thus, after the lifting member moves a certain distance toward the first wall, the limit plate abuts the adjusting member, preventing the lifting member from moving further; and after the lifting member moves a certain distance away from the first wall, the limit plate abuts the bottom cover, preventing the lifting member from moving further, thus limiting the range of movement of the lifting member.

[0015] In some embodiments, one side of the limiting plate is connected to the lifting member, and the other side of the limiting plate is constructed with a first sliding portion protruding toward the bottom cover. A corresponding through hole is opened on the bottom cover, and the first sliding portion is inserted into the through hole and can slide along the first direction relative to the through hole.

[0016] Therefore, when the adjusting member rotates, the lifting member is restricted by the through hole through the first sliding portion and cannot rotate, thereby converting the rotation into translational movement and sliding relative to the through hole along the first direction.

[0017] In some embodiments, the lifting member is configured with a second sliding portion protruding toward the bottom cover on one side of the bottom cover, a through hole is correspondingly provided on the bottom cover, the second sliding portion is inserted into the through hole and can slide relative to the through hole along the first direction.

[0018] Therefore, when the adjusting member rotates, the lifting member is restricted by the through hole through the second sliding portion and cannot rotate, thereby converting the rotation into translational movement and sliding relative to the through hole along the first direction.

[0019] In some embodiments, the first wall is provided with an opening penetrating the wall surface, and a flexible member is provided to cover the opening.

[0020] As a result, the electronic device is partially in contact with the flexible member, which helps to avoid scratching the electronic device.

[0021] In some embodiments, a clamping member is provided on a side of the bottom cover away from the adjusting member, the clamping member is provided with a spherical clamping space and an adjustment notch connected to the clamping space, and a thread is constructed on the outer side of the clamping member for connecting to the seat assembly.

[0022] Thus, the magnetic connection device can be connected to the seat assembly via the clamping member.

[0023] In some embodiments, the first wall is provided with a receiving groove, and the second magnetic member is disposed in the receiving groove.

[0024] Thus, the second magnetic member can be firmly fixed and confined in the accommodating groove.

[0025] In a second aspect, the present application further provides an electronic device bracket, comprising a base assembly and the magnetic connection device as described in the first aspect above, wherein the base assembly is used to connect to an external bearing surface, and the base assembly is connected to the fixed shell.

[0026] Since the electronic device holder includes a magnetic connection device capable of changing the magnetic attraction force, the electronic device holder can not only firmly adsorb the electronic device by increasing the magnetic attraction force, but also make it easier for the user to pick up the electronic device by decreasing the magnetic attraction force, thereby improving the user experience.

In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0044] Below, this application is described in detail.

[0045] Magnetic attachment devices are used to secure electronic devices, allowing users to use them at a comfortable and effortless angle. These devices include magnetic components, whose magnetic attraction secures the electronic device to the device. To ensure a secure attachment of the electronic device, magnetic components with strong attraction are typically used.

[0046] However, this requires a lot of force to remove the electronic device from the magnetic connection device, which leads to a poor user experience. Magnetic parts with smaller magnetic attraction forces may also have problems with weak adhesion.

[0047] The present application provides a magnetic connection device, which includes: a fixed shell having a storage space, the fixed shell including a first wall capable of supporting an electronic device; a lifting assembly, at least partially located in the storage space; a first magnetic part, located in the storage space and arranged on a side of the lifting assembly close to the first wall, for providing a magnetic attraction force for adsorbing the electronic device; a second magnetic part, arranged on the first wall, for providing a magnetic attraction force for adsorbing the electronic device; wherein the lifting assembly is configured to drive the first magnetic part to move closer to or away from the first wall.

[0048] Because the lifting assembly is configured to move the first magnetic member toward or away from the first wall, the distance between the first magnetic member and the first wall can be changed, thereby increasing or decreasing the magnetic attraction of the first magnetic member to the electronic device located on the first wall. Since the second magnetic member is provided on the first wall, regardless of how the magnetic attraction provided by the first magnetic member changes, the second magnetic member can still provide a certain magnetic attraction to hold the electronic device in place. This helps prevent the electronic device from falling due to a sudden decrease in the magnetic attraction of the first magnetic member during user adjustment. When the first magnetic member is close to the first wall, the first and second magnetic members work together to provide a stronger magnetic attraction, making the magnetic connection device suitable for securing heavier electronic devices and improving the secure attachment. When the magnetic member moves away from the first wall, the magnetic attraction decreases, allowing the user to easily remove the electronic device. Because the lifting assembly is at least partially located within the storage space and the first magnetic member is also located within the storage space, the fixed housing protects and contains the first magnetic member and at least a portion of the lifting assembly.

[0049] The following is a description with reference to the accompanying drawings.

[0050] Figure 1 A three-dimensional schematic diagram of a magnetic connection device provided in one embodiment of the present application; Figure 2 An exploded perspective diagram of a magnetic connection device provided in one embodiment of the present application; Figure 3 An exploded perspective diagram of a magnetic connection device from one perspective provided by another embodiment of the present application; Figure 4 for Figure 3 An exploded perspective diagram of the magnetic connection device from another perspective; Figure 5 An exploded perspective diagram of a magnetic connection device provided in yet another embodiment of the present application.

[0051] The present application provides a magnetic connection device, such as Figures 1 to 5 As shown, the magnetic connection device includes: a fixed shell 10, having a accommodating space, the fixed shell 10 includes a first wall 11 capable of carrying an electronic device; a lifting assembly 20, at least partially located in the accommodating space; a first magnetic part 30, located in the accommodating space, and arranged on a side of the lifting assembly 20 close to the first wall 11, for providing a magnetic attraction force for adsorbing the electronic device; a second magnetic part 60, arranged on the first wall 11, for providing a magnetic attraction force for adsorbing the electronic device; wherein the lifting assembly 20 is configured to be able to drive the first magnetic part 30 to move closer to or away from the first wall 11.

[0052] The magnetic connection device includes a fixed housing 10, a lifting assembly 20, a first magnetic member 30, and a second magnetic member 60. The lifting assembly 20 is at least partially housed within the fixed housing 10, and the first magnetic member 30 is entirely housed within the fixed housing 10. The lifting assembly 20 is connected to the first magnetic member 30 and can drive the first magnetic member 30 to move within the fixed housing 10. The second magnetic member 60 is disposed on the first wall 11. The second magnetic member 60 can be disposed on the side of the first wall 11 facing the storage space or on the side of the first wall 11 facing away from the storage space.

[0053] The fixed housing 10 includes a first wall 11. The first wall 11 has a relatively flat surface, and the electronic device can be placed on the first wall 11. The fixed housing 10 encloses a storage space. The first magnetic member 30 and the second magnetic member 60 are located in the storage space and face the first wall 11. The first magnetic member 30 and the second magnetic member 60 can provide a magnetic attraction force, causing the electronic device to be attracted to the first wall 11. The first magnetic member 30 and the second magnetic member 60 can be configured in a ring shape.

[0054] Exemplarily, the first magnetic member 30 and the second magnetic member 60 are magnets.

[0055] Portions of the lifting assembly 20 are movable relative to the fixed housing 10. Specifically, the first wall 11, the first magnetic member 30, and the lifting assembly 20 are arranged along a first direction Z. The lifting assembly 20 includes a lifting member 22 that is reciprocally movable along the first direction Z. The first magnetic member 30 is disposed on the lifting member 22, enabling the first magnetic member 30 to move along with the lifting member 22 along the first direction Z, thereby varying the distance between the first magnetic member 30 and the first wall 11. The first direction Z is perpendicular to the extension direction of the first wall 11.

[0056] Optionally, the lifting assembly 20 is entirely accommodated in the accommodation space. The lifting assembly 20 includes a cylinder, the telescopic end of the cylinder facing the first wall 11 and connected to the first magnetic member 30. The first magnetic member 30 moves along the first direction Z by controlling the extension and contraction of the cylinder.

[0057] In the technical solution of the embodiment of the present application, since the lifting assembly 20 is configured to move the first magnetic member 30 toward or away from the first wall 11, the distance between the first magnetic member 30 and the first wall 11 can be changed, thereby increasing or decreasing the magnetic attraction of the first magnetic member 30 on the electronic device located on the first wall 11. Since the second magnetic member 60 is provided on the first wall 11, regardless of how the magnetic attraction provided by the first magnetic member 30 changes, the second magnetic member 60 can still provide a certain magnetic attraction to hold the electronic device. This helps prevent the magnetic attraction of the first magnetic member 30 from suddenly decreasing during user adjustment, causing the electronic device to fall. When the first magnetic member 30 is close to the first wall 11, the first and second magnetic members 30, 60, can work together to provide a strong magnetic attraction, making the magnetic connection device suitable for securing heavy electronic devices and improving the firmness of the attraction. When the first magnetic member 30 is away from the first wall 11, the magnetic attraction decreases, allowing the user to easily pick up the electronic device. Since the lifting assembly 20 is at least partially located in the accommodation space, and the first magnetic member 30 and the second magnetic member 60 are located in the accommodation space, the fixed shell 10 can protect and accommodate the first magnetic member 30 , the second magnetic member 60 and at least part of the lifting assembly 20 .

[0058] In an optional embodiment, the lifting assembly 20 includes a lifting member 22 partially housed within the accommodating space. The lifting member 22 extends in a first direction Z. Threads are formed on the peripheral surface of the lifting member 22, and the lifting member 22 is threadedly connected to the fixed housing 10. The side of the lifting member 22 proximate to the first wall 11 is connected to the first magnetic member 30, while the other side of the lifting member 22 extends through the fixed housing 10. The lifting member 22 can be rotated to change its position relative to the first wall 11, thereby changing the distance between the first magnetic member 30 and the first wall 11.

[0059] Furthermore, the lifting assembly 20 further includes an adjusting member 21, which is connected to a side of the lifting member 22 away from the first wall 11. The position of the lifting member 22 relative to the first wall 11 is changed by rotating the adjusting member 21.

[0060] In some embodiments, as Figures 2 to 5 As shown, the magnetic connection device also includes a bottom cover 40 connected to the fixed shell 10, and the bottom cover 40 and the first wall 11 are opposite to each other along the first direction Z. The lifting assembly 20 includes an adjusting member 21 and a lifting member 22. One side of the lifting member 22 is connected to the first magnetic member 30, and the other side of the lifting member 22 passes through the fixed shell 10 and is arranged on the bottom cover 40 in a manner that can slide along the first direction Z. The adjusting member 21 is located between the bottom cover 40 and the fixed shell 10. The adjusting member 21 surrounds the lifting member 22 and is connected to the lifting member 22 through a threaded structure. The threaded structure includes a spiral groove arranged with the first direction Z as the axis and a spiral protrusion inserted in the spiral groove. One of the spiral groove and the spiral protrusion is arranged on the adjusting member 21, and the other of the spiral groove and the spiral protrusion is arranged on the lifting member 22.

[0061] The magnetic connection device further includes a bottom cover 40. The first wall 11 and the bottom cover 40 are respectively located on both sides of the lifting assembly 20 in the first direction Z. The bottom cover 40 is connected to the fixed housing 10.

[0062] The lifting assembly 20 includes an adjustment member 21 and a lifting member 22. The adjustment member 21 is located between the fixed housing 10 and the bottom cover 40 and is rotatable relative to the fixed housing 10 and the bottom cover 40 about a first direction Z. Both sides of the adjustment member 21 in the first direction Z abut against the fixed housing 10 and the bottom cover 40, respectively.

[0063] A portion of the lifter 22 is housed in the accommodation space, while another portion of the lifter 22 extends through the fixed housing 10 and exits the accommodation space. One side of the lifter 22 within the accommodation space is connected to the first magnetic member 30, while the other side of the lifter 22 is mounted to the bottom cover 40 so as to be slidable along the first direction Z.

[0064] The lifting member 22 and the adjusting member 21 are connected by a threaded structure. The threaded structure includes a spiral groove and a spiral protrusion, which is capable of being inserted into the spiral groove. Specifically, the spiral protrusion can be formed on the circumferential surface of the lifting member 22. The adjusting member 21 is disposed around the lifting member 22, and the surface of the adjusting member 21 facing the lifting member 22 is configured with a spiral groove. The adjusting member 21 can rotate about the lifting member 22, and the spiral groove pushes the spiral protrusion to move, thereby moving the lifting member 22 in the first direction Z.

[0065] Alternatively, a spiral groove may be formed on the circumferential surface of the lifting member 22. The adjusting member 21 may be disposed around the lifting member 22, and a spiral protrusion may be formed on the surface of the adjusting member 21 facing the lifting member 22. The adjusting member 21 may rotate about the lifting member 22, and the spiral protrusion may push the spiral groove to move, thereby moving the lifting member 22 in the first direction Z.

[0066] Furthermore, an undulating anti-slip pattern is formed on the peripheral surface of the adjusting member 21 .

[0067] Therefore, by rotating the adjusting member 21 , the thread in the adjusting member 21 can push the lifting member 22 to move along the first direction Z, so that the lifting member 22 can drive the first magnetic member 30 to move closer to or away from the first wall 11 to adjust the magnetic attraction.

[0068] In some embodiments, as Figures 2 to 5 As shown, a limiting column 12 is constructed on one side of the fixed shell 10 facing the adjusting member 21 and protruding toward the adjusting member 21. The adjusting member 21 is provided with a limiting groove 211 whose extension direction is perpendicular to the first direction Z. The limiting column 12 is inserted into the limiting groove 211 and can slide along the limiting groove 211, and is used to limit the rotation angle of the adjusting member 21 through the cooperation between the limiting column 12 and the limiting groove 211.

[0069] A retaining post 12 is formed on the side of the fixed housing 10 facing the adjusting member 21, protruding toward the adjusting member 21. The adjusting member 21 defines a retaining slot 211 to accommodate the retaining post 12. The retaining slot 211 extends perpendicular to the first direction Z and partially surrounds the lifting member 22. When the adjusting member 21 rotates in one direction relative to the fixed housing 10, the retaining post 12 moves along the extending direction of the retaining slot 211 until the retaining post 12 abuts against a side wall of the retaining slot 211, preventing the adjusting member 21 from rotating further in that direction.

[0070] A plurality of limiting posts 12 can be provided, and the plurality of limiting posts 12 are arranged in a centrally symmetrical manner on the fixed housing 10. A plurality of corresponding limiting slots 211 are provided on the adjusting member 21.

[0071] In some embodiments, a limiting column 12 is constructed on one side of the adjusting member 21 toward the fixed shell 10 and protrudes toward the fixed shell 10. The fixed shell 10 is provided with a limiting groove 211 whose extension direction is perpendicular to the first direction Z. The limiting column 12 is inserted into the limiting groove 211 and can slide along the limiting groove 211, and is used to limit the rotation angle of the adjusting member 21 through the cooperation between the limiting column 12 and the limiting groove 211.

[0072] Thus, the adjusting member 21 can rotate in one direction to a position where the groove wall on one side of the limiting groove 211 contacts the limiting column 12 and is limited by the limiting column 12, and the adjusting member 21 can rotate in another direction to a position where the groove wall on the other side of the limiting groove 211 contacts the limiting column 12 and is limited by the limiting column 12, thereby limiting the rotation angle of the adjusting member 21.

[0073] In some embodiments, the fixed housing 10 is connected to the bottom cover 40 via a connecting post. One end of the connecting post is connected to the fixed housing 10, and the other end of the connecting post is connected to the bottom cover 40. The connecting post spans the adjustment member 21 and avoids the rotation path of the adjustment member 21.

[0074] In some embodiments, the limiting post 12 passes through the limiting slot 211 and is connected to the bottom cover 40 .

[0075] The fixed housing 10 is provided with a limiting post 12, and the adjusting member 21 has a limiting slot 211 extending therethrough. The limiting post 12 passes through the limiting slot 211 and connects to the bottom cover 40. When the adjusting member 21 is rotated, the bottom cover 40, the fixed housing 10, and the lifting member 22 do not rotate with the adjusting member 21.

[0076] Thus, the fixing shell 10 is connected to the bottom cover 40 via the limiting pillars 12 .

[0077] In some embodiments, as Figures 3 to 5As shown, the magnetic connection device also includes a limit plate 50, and the limit plate 50 is connected to the side of the lifting member 22 close to the bottom cover 40. A limit cavity is constructed between the adjusting member 21 and the bottom cover 40, and the limit plate 50 is located in the limit cavity, wherein the limit plate 50 can move between the two side walls of the limit cavity in the first direction Z to limit the movement range of the lifting member 22 along the first direction Z.

[0078] The magnetic connection device also includes a limiting plate 50. The bottom cover 40 and / or the adjusting member 21 are recessed, and the bottom cover 40 and the adjusting member 21 abut against each other to form a limiting cavity, in which the limiting plate 50 is positioned. The thickness of the limiting plate 50 along the first direction Z is less than the distance between the two side walls forming the limiting cavity along the first direction Z. The limiting plate 50 is connected to the lifting member 22 and can move with the lifting member 22 within the limiting space.

[0079] Specifically, the lifting member 22 sequentially passes through the fixed housing 10 and the adjusting member 21. The side of the lifting member 22 closest to the bottom cover 40 is connected to the limiting plate 50. Within the same projection plane perpendicular to the first direction Z, the projection of the limiting plate 50 partially overlaps with that of the adjusting member 21 and lies within the projection of the bottom cover 40. A limiting cavity capable of accommodating the limiting plate 50 is defined between the bottom cover 40 and the adjusting member 21, with a gap existing between the limiting plate 50 and the bottom cover 40 and / or the adjusting member 21.

[0080] During use, the adjusting member 21 is rotated in one direction, and the lifting member 22 is pushed by the threads toward the first wall 11, driving the limit plate 50 toward the adjusting member 21 until the limit plate 50 abuts against the adjusting member 21, preventing the lifting member 22 from moving further, thereby limiting the minimum distance between the lifting member 22 and the first wall 11. The adjusting member 21 is rotated in the other direction, and the lifting member 22 is pushed away from the first wall 11 by the threads, driving the limit plate 50 toward the bottom cover 40 until the limit plate 50 abuts against the bottom cover 40, preventing the lifting member 22 from moving further, thereby limiting the maximum distance between the lifting member 22 and the first wall 11.

[0081] Furthermore, the limiting plate 50 and the limiting post 12 can be arranged in cooperation with each other. When the limiting post 12 abuts against one end of the limiting groove 211, one side of the limiting plate 50 abuts against the bottom cover 40; when the limiting post 12 abuts against the other end of the limiting groove 211, the other side of the limiting plate 50 abuts against the adjusting member 21.

[0082] Thus, after the lifting member 22 moves a certain distance toward the first wall 11, the limit plate 50 abuts the adjusting member 21, preventing the lifting member 22 from moving further. After the lifting member 22 moves a certain distance away from the first wall 11, the limit plate 50 abuts the bottom cover 40, preventing the lifting member 22 from moving further. This limits the range of movement of the lifting member 22.

[0083] In some embodiments, as Figure 4 and Figure 5 As shown, one side of the limit plate 50 is connected to the lifting member 22, and the other side of the limit plate 50 is constructed with a first sliding portion 51 protruding toward the bottom cover 40. A through hole 41 is correspondingly opened on the bottom cover 40. The first sliding portion 51 is inserted into the through hole 41 and can slide along the first direction Z relative to the through hole 41.

[0084] The lifting member 22 is mounted on the bottom cover 40 via a limiting plate 50 so as to be slidable in a first direction Z. One side of the limiting plate 50 is connected to the lifting member 22, and the other side of the limiting plate 50 is formed with a first sliding portion 51 that protrudes toward the bottom cover 40. The bottom cover 40 defines a through hole 41, and the first sliding portion 51 is partially received in the through hole 41 and is slidable relative to the through hole 41 in the first direction Z.

[0085] Optionally, there are multiple first sliding parts 51, and the bottom cover 40 has multiple through holes 41, and the first sliding parts 51 correspond one to one with the through holes 41. When the adjusting member 21 rotates, the through holes 41 limit the rotation of the first sliding part 51, so that the first sliding part 51 can only move along the first direction Z.

[0086] Alternatively, the first sliding portion 51 is located at the center of the limiting plate 50, and the cross-section of the first sliding portion 51 perpendicular to the first direction Z is non-circular, such as polygonal, teardrop-shaped, arc-shaped, etc. This prevents the first sliding portion 51 from rotating relative to the bottom cover 40 and allows it to move only along the first direction Z.

[0087] Alternatively, the first sliding portion 51 is eccentrically disposed relative to the center of the limiting plate 50 , so that the first sliding portion 51 cannot rotate relative to the bottom cover 40 and can only move along the first direction Z.

[0088] Therefore, when the adjusting member 21 rotates, the lifting member 22 is restricted by the through hole 41 through the first sliding portion 51 and cannot rotate, thereby converting the rotation into translational movement and sliding along the first direction Z relative to the through hole 41.

[0089] In some embodiments, as Figure 2 As shown, the lifting member 22 has a second sliding portion 23 protruding toward the bottom cover 40 on one side thereof, and a through hole 41 is correspondingly provided on the bottom cover 40 . The second sliding portion 23 is inserted into the through hole 41 and can slide along the first direction Z relative to the through hole 41 .

[0090] One side of the lifting member 22 is connected to the first magnetic member 30, and the other side of the lifting member 22 passes through the fixed housing 10 and the adjusting member 21 in sequence. A second sliding portion 23 is formed on the side of the lifting member 22 away from the first magnetic member 30, protruding toward the bottom cover 40. A corresponding through-hole 41 is defined in the bottom cover 40. The second sliding portion 23 is partially received in the through-hole 41 and is able to slide relative to the through-hole 41 in the first direction Z.

[0091] Optionally, there are multiple second sliding parts 23, and the bottom cover 40 has multiple through holes 41, and the second sliding parts 23 correspond one to one with the through holes 41. When the adjusting member 21 rotates, the through holes 41 limit the rotation of the second sliding part 23, so that the second sliding part 23 can only move along the first direction Z.

[0092] Alternatively, the second sliding portion 23 is located at the axis of the lifting member 22, and the cross-section of the second sliding portion 23 perpendicular to the first direction Z is non-circular, such as polygonal, teardrop-shaped, arc-shaped, etc. This prevents the second sliding portion 23 from rotating relative to the bottom cover 40 and allows it to move only along the first direction Z.

[0093] Alternatively, the second sliding portion 23 is eccentrically disposed relative to the axis of the lifting member 22 , so that the second sliding portion 23 cannot rotate relative to the bottom cover 40 and can only move along the first direction Z.

[0094] Therefore, when the adjusting member 21 rotates, the lifting member 22 is restricted by the through hole 41 through the second sliding portion 23 and cannot rotate, thereby converting the rotation into translational movement and sliding along the first direction Z relative to the through hole 41.

[0095] In some embodiments, as Figure 3 and Figure 5 As shown, the first wall 11 is provided with an opening penetrating the wall surface, and a flexible member 13 is provided to cover the opening.

[0096] The first wall 11 has an opening, and the accommodation space is connected to the outside through the opening. The flexible member 13 covers the opening. The first magnetic member 30 can be moved to a position in contact with the flexible member 13, which helps to further reduce the distance from the electronic device and provide a greater magnetic attraction.

[0097] Exemplarily, the flexible member 13 is a surface sticker.

[0098] As a result, the electronic device is partially in contact with the flexible member 13, which helps to prevent the electronic device from being scratched.

[0099] In some embodiments, as Figure 4 and Figure 5 As shown, a clamping member 42 is provided on the side of the bottom cover 40 away from the adjusting member 21. The clamping member 42 has a spherical clamping space and an adjustment notch connected to the clamping space. The outer side of the clamping member 42 is threaded for connection to the seat assembly.

[0100] The spherical clamping space is used to cooperate with the ball head of the seat body assembly; the threaded mating portion is used to cooperate with the cylindrical adjustment piece to adjust the size of the spherical clamping space; during use, the ball head of the seat body assembly can be clamped in the spherical clamping space, and then the spherical clamping space can be used to clamp the ball head of the seat body assembly by adjusting the adjustment piece.

[0101] Thus, the magnetic connection device can be connected to the seat assembly via the clamping member 42 .

[0102] In some embodiments, as Figure 5 As shown, the first wall 11 defines a receiving groove 14 , and the second magnetic member 60 is disposed in the receiving groove 14 .

[0103] The second magnetic member 60 is formed in an annular shape around the opening, and an annular receiving groove 14 is defined on the first wall 11. The second magnetic member 60 is placed in the receiving groove 14. The receiving groove 14 can be formed on the side of the first wall 11 facing the receiving space, and the side of the electronic device that contacts the first wall 11 is attracted by the second magnetic member 60 on the other side of the first wall 11.

[0104] A receiving groove 14 can also be constructed on the side of the first wall 11 away from the receiving space. The flexible member 13 is flush with the second magnetic member 60 to form a flat surface. The side of the second magnetic member 60 away from the receiving space serves as the first wall 11 to support the electronic device, allowing the electronic device to directly contact and be attracted by the second magnetic member 60. Furthermore, the flexible member 13 covers the second magnetic member 60 and the opening.

[0105] Thus, the second magnetic member 60 can be firmly fixed and confined in the receiving groove 14 .

[0106] In a second aspect, the present application further provides an electronic device bracket, comprising a seat assembly and the magnetic connection device as described in the first aspect above, wherein the base assembly is used to connect to an external bearing surface, and the base assembly is connected to a fixed shell.

[0107] Since the electronic device holder includes a magnetic connection device capable of changing the magnetic attraction force, the electronic device holder can not only firmly adsorb the electronic device by increasing the magnetic attraction force, but also make it easier for the user to pick up the electronic device by decreasing the magnetic attraction force, thereby improving the user experience.

[0108] A specific embodiment of the present application is described below.

[0109] The fixed shell 10 and the bottom cover 40 are spaced apart from each other along the first direction Z and are connected by a limiting post 12. A second magnetic member 60 is provided on the surface of the fixed shell 10 away from the bottom cover 40. The fixed shell 10 and the bottom cover 40 clamp the knob member (adjustment member 21) from both sides, and the knob member (adjustment member 21) can rotate between the fixed shell 10 and the bottom cover 40. An annular groove is provided on the knob member (adjustment member 21), and the center angle of the annular groove is 90 degrees. The number of arc-shaped grooves provided can be 1 to 3. The limiting post 12 is partially accommodated in the arc-shaped groove, thereby limiting the rotation angle range of the knob member (adjustment member 21) relative to the fixed shell 10.

[0110] The lifter 22 is partially housed within the fixed housing 10 and is connected to the knob (adjustment member 21) via threads. One side of the lifter 22 is connected to the first magnetic member 30, while the other side of the lifter 22 extends through the fixed housing 10 and is mounted on the bottom cover 40 so that it can slide in a first direction Z. When the knob (adjustment member 21) is rotated in one direction, the lifter 22 descends due to the threads. When the knob (adjustment member 21) is rotated in the other direction, the lifter 22 lowers and returns to its original position.

[0111] Thus, by raising the first magnetic member 30, the electronic device is subjected to a greater magnetic attraction force, providing a better adsorption effect; by lowering the first magnetic member 30, the electronic device is subjected to a smaller magnetic attraction force, allowing the user to easily pick up the electronic device. While achieving a good clamping effect, it also ensures a good user experience.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.
