Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of magnetic attraction equipment, and particularly relates to a magnetic attraction structure. BACKGROUND

[0002] The magnetic attraction structure is attracted by a magnet, can contact and connect two objects through the magnetic attraction force of the magnet, does not cause damage to the objects, and can be quickly and repeatedly disassembled. In view of the non-damage and easy disassembly characteristics of the magnet attraction, the magnetic attraction structure is widely applied to various products.

[0003] However, the magnetic attraction structure in the related art still has certain problems in some use scenarios, so that the magnetic attraction structure is inconvenient to separate from the magnetic attraction type equipment. For example, when the magnetic attraction structure is applied to a wireless charger, in order to achieve close contact between the mobile phone and the wireless charger, prevent the wireless charger from falling off during the movement of the user, and achieve a good near-distance charging effect, the magnetic attraction force of the magnet needs to be increased. However, the problem caused by the excessive magnetic attraction force is that when the wireless charger and the mobile phone are separated after the charging is completed, the user needs to use both hands to force them apart, and there is a risk of the mobile phone or the wireless charger falling off, the charging cable falling off, and the like. SUMMARY

[0004] The application aims to provide a magnetic attraction structure to solve the problem that the magnetic attraction structure in the related art is inconvenient to separate from the magnetic attraction type equipment.

[0005] To solve the above technical problems, the application is implemented as follows:

[0006] The application embodiment provides a magnetic attraction structure, which comprises a base, a magnetic part movably arranged on the base along a first direction, and a pressing assembly comprising a pressing part and a connecting rod part. The pressing part is movably connected with the base along a second direction, one end of the connecting rod part is movably connected with the magnetic part, and the other end of the connecting rod part is movably connected with the pressing part. The pressing part drives the magnetic part to move along the first direction through the connecting rod part, so that the magnetic attraction structure has a first state and a second state. In the first state, the pressing part is close to the magnetic part, and the magnetic part is away from the base along the first direction. In the second state, the pressing part is away from the magnetic part, and the magnetic part is supported on the base.

[0007] In an embodiment of the present application, a magnetic structure includes a base, a magnetic part, and a pressing assembly. The pressing assembly includes a pressing part and a connecting rod, one end of the connecting rod is movably connected to the magnetic part, and the other end of the connecting rod is movably connected to the pressing part. The pressing part can move relative to the base in a second direction. In this way, during the movement of the pressing part relative to the base, the connecting rod can drive the magnetic part to move in the first direction, so that the magnetic structure has a first state and a second state. In the first state, the pressing part is close to the magnetic part, and the magnetic part is away from the base in the first direction, which increases the distance between the magnetic part and the magnetic device and reduces the suction force between the magnetic part and the magnetic device, thereby facilitating the removal of the magnetic device and avoiding the situation where the connecting line of the magnetic structure breaks when the magnetic structure is directly pulled. At the same time, since the suction force between the magnetic part and the magnetic device can be reduced by operating the pressing part when the magnetic structure and the magnetic device need to be separated, the suction force of the magnetic part can be increased, so that the suction force between the magnetic part and the magnetic device is enhanced in the second state, avoiding the separation of the magnetic device from the magnetic part.

[0018] The following combination Figure 1 and Figure 2 The magnetic attraction structure according to the embodiment of the present application is described.

[0019] like Figure 1 As shown, the magnetic attraction structure according to some embodiments of the present application includes: a base 1; a magnetic part 2, which is movably arranged on the base 1 along a first direction; a pressing component 3, the pressing component 3 includes a pressing part 30 and a connecting rod part 32, the pressing part 30 is movably connected to the base 1 along the second direction, one end of the connecting rod part 32 is movably connected to the magnetic part 2, and the other end of the connecting rod part 32 is movably connected to the pressing part 30, and the pressing part 30 drives the magnetic part 2 to move along the first direction through the connecting rod part 32, so that the magnetic attraction structure has a first state and a second state; in the first state, the pressing part 30 is close to the magnetic part 2, and the magnetic part 2 is away from the base 1 along the first direction; in the second state, the pressing part 30 is away from the magnetic part 2, and the magnetic part 2 is supported on the base 1.

[0020] In an embodiment of the present application, the magnetic structure includes a base 1, a magnetic part 2 and a pressing assembly 3. The pressing assembly 3 includes a pressing part 30 and a connecting rod part 32, one end of the connecting rod part 32 is movably connected to the magnetic part 2, and the other end of the connecting rod part 32 is movably connected to the pressing part 30, and the pressing part 30 can move relative to the base 1 along the second direction. In this way, during the movement of the pressing part 30 relative to the base 1, the connecting rod part 32 can drive the magnetic part 2 to move along the first direction, so that the magnetic structure has a first state and a second state. Among them, in the first state, the pressing part 30 is close to the magnetic part 2, and the magnetic part 2 is away from the base 1 along the first direction, which increases the distance between the magnetic part 2 and the magnetic device and reduces the suction force between the magnetic part 2 and the magnetic device, thereby facilitating the picking up of the magnetic device and avoiding the situation where the connecting line of the magnetic structure is broken when the magnetic structure is directly pulled. At the same time, since the suction force between the magnetic part 2 and the magnetic device can be reduced by operating the pressing part 30 when the magnetic structure and the magnetic device need to be separated, the adsorption force of the magnetic part 2 can be increased, so that the adsorption force between the magnetic part 2 and the magnetic device is enhanced in the second state, thereby preventing the magnetic device from separating from the magnetic part 2.

[0021] Specifically, in the second state, the pressing portion 30 is away from the magnetic portion 2, and the magnetic portion 2 is supported on the base 1, so that the distance between the magnetic portion 2 and the magnetic device is relatively close, and thus the adsorption capacity is strong, which can prevent the magnetic device from falling off; in the process of switching from the second state to the first state, the pressing portion 30 moves in the direction close to the magnetic portion 2, driving the connecting rod portion 32 to move, and one end of the connecting rod portion 32 drives the magnetic portion 2 to move along the first direction, so that the magnetic portion 2 is away from the base 1, and the magnetic structure is in the first state, thereby making the magnetic portion 2 away from the magnetic device, reducing the adsorption force between the magnetic portion 2 and the magnetic device, so as to facilitate the picking up of the magnetic device. In the process of switching from the first state to the second state, the pressing portion 30 moves in the direction away from the magnetic portion 2, driving the connecting rod portion 32 to move, and one end of the connecting rod portion 32 drives the magnetic portion 2 to move along the first direction toward the direction close to the base 1 until the magnetic portion 2 is supported on the base 1, so that the magnetic portion 2 is reset.

[0022] It can be understood that by driving the pressing part 30 to move the pressing part 30 toward the magnetic part 2, the magnetic structure is switched to the first state. The magnetic structure is attracted to the magnetic device, providing support, power supply and other functions for the magnetic device. Among them, the magnetic structure is attracted to the magnetic device through the magnetic part 2, and the magnetic device is adsorbed on the base 1 of the magnetic structure. Therefore, when the pressing part 30 is pressed, when the magnetic part 2 is away from the base 1, the adsorption force between the magnetic part 2 and the magnetic device can be reduced, thereby facilitating the removal of the magnetic device.

[0023] like Figure 2As shown, according to some embodiments of the present application, the connecting rod portion 32 includes a first connecting rod 320, and the first connecting rod 320 has a first end 322 and a second end 324; the first end 322 is hinged to the pressing portion 30, and the second end 324 is hinged to the magnetic portion 2, and the first connecting rod 320 is tilted relative to the first direction; in the first state, the first end 322 approaches the magnetic portion 2 along the second direction, and the second end 324 moves away from the base 1 along the first direction; in the second state, the first end 322 moves away from the magnetic portion 2 along the second direction, and the second end 324 approaches the base 1 along the first direction.

[0024] In this embodiment, the connecting rod portion 32 includes a first connecting rod 320, and the first connecting rod 320 has a first end 322 and a second end 324. The first end 322 is hinged to the pressing portion 30, and the second end 324 is hinged to the magnetic portion 2. When the pressing portion 30 moves toward the magnetic portion 2, the pressing portion 30 drives the first end 322 of the first connecting rod 320 to approach the magnetic portion 2 in the second direction, and then drives the magnetic portion 2 to move in the first direction away from the base 1 through the second end 324 of the first connecting rod 320 until the magnetic structure is in the first state. When the pressing portion 30 moves toward the magnetic portion 2, the pressing portion 30 drives the first end 322 of the first connecting rod 320 to move away from the magnetic portion 2 in the second direction, and then causes the second end 324 of the first connecting rod 320 to approach the base 1 in the first direction, and drives the magnetic portion 2 to move in the direction close to the base 1 until the magnetic structure is in the second state.

[0025] It can be understood that the first connecting rod 320 is tilted relative to the first direction. Specifically, from the first end 322 to the second end 324, the first connecting rod 320 is tilted toward the top of the magnetic part 2. When the pressing part 30 approaches the magnetic part 2, the first end 322 of the first connecting rod 320 rotates relative to the pressing part 30 and approaches the magnetic part 2 driven by the pressing part 30. The second end 324 of the first connecting rod 320 rotates relative to the magnetic part 2 and moves along the first direction toward the top of the magnetic part 2 under the push of the first connecting rod 320, thereby driving the magnetic part 2 to move toward the top.

[0026] like Figure 1 As shown, according to some embodiments of the present application, the pressing part 30 includes: a shell 300, the shell 300 is movably connected to the base 1 along the second direction; a second connecting rod 302, the second connecting rod 302 extends along the second direction, one end of the second connecting rod 302 is connected to the shell 300, and the other end of the second connecting rod 302 is connected to the first end 322 of the first connecting rod 320.

[0027] In this embodiment, the pressing part 30 includes a shell 300 and a second connecting rod 302. The shell 300 is movably connected to the base 1. One end of the second connecting rod 302 is connected to the shell 300, and the other end is connected to the first end 322 of the first connecting rod 320. In this way, when the pressing part 30 approaches the magnetic part 2, the shell 300 drives the second connecting rod 302 to approach the magnetic part 2, and then the second connecting rod 302 drives the first connecting rod 320 to move, thereby realizing the movement of the magnetic part 2 along the first direction.

[0028] In a specific application, the second connecting rod 302 is fixed on the housing 300 .

[0029] Furthermore, the second connecting rod 302 is hinged to the first end 322 of the first connecting rod 320 .

[0030] like Figure 2 As shown, according to some embodiments of the present application, the base 1 includes: a bottom plate 10, a shell 300 movably provided on the bottom plate 10, a mounting seat 102 is provided on the bottom plate 10, and the magnetic part 2 is movably provided on the mounting seat 102; a vertical wall 12, provided on the bottom plate 10 and enclosing a cavity with the bottom plate 10, the magnetic part 2 and the mounting seat 102 are provided in the cavity, the shell 300 is located on the side of the vertical wall 12 away from the cavity, a through hole 120 is provided on the vertical wall 12, the second connecting rod 302 is passed through the through hole 120 and is movably connected to the through hole 120 along the second direction; wherein, in the first state, the magnetic part 2 moves away from the mounting seat 102 along the first direction, and in the second state, the magnetic part 2 is in contact with the mounting seat 102.

[0031] In this embodiment, the base 1 includes a base plate 10 and a vertical wall 12 disposed on the base plate 10. The vertical wall 12 and the base plate 10 enclose a cavity. The mounting seat 102 and the magnetic portion 2 on the base plate 10 are both disposed within the cavity, and the housing 300 is located outside the cavity. The housing 300 is movably connected to the base plate 10, and the magnetic portion 2 is movably connected to the mounting seat 102. The vertical wall 12 has a through hole 120, and a second connecting rod 302 is disposed within the through hole 120 to connect the housing 300 and the first connecting rod 320. In the second state, the magnetic part 2 is in contact with the mounting base 102, and the mounting base 102 provides support for the magnetic part 2; in the process of switching from the second state to the first state, the shell 300 drives the second connecting rod 302 to move in the direction close to the magnetic part 2, and the second connecting rod 302 drives the first end 322 of the first connecting rod 320 to approach the magnetic part 2, so that the second end 324 of the first connecting rod 320 moves in the direction away from the mounting base 102, and then drives the magnetic part 2 away from the mounting base 102 until the magnetic structure is in the first state, increasing the distance between the magnetic part 2 and the magnetic device, making it easier to pick up the magnetic device; in the process of switching from the first state to the second state, the shell 300 drives the second connecting rod 302 to move in the direction away from the magnetic part 2, and the second connecting rod 302 drives the first end 322 of the first connecting rod 320 away from the magnetic part 2, so that the second end 324 of the first connecting rod 320 moves in the direction close to the mounting base 102, and then drives the magnetic part 2 to approach the mounting base 102 until the magnetic structure is in the second state.

[0032] In a specific application, the bottom of the housing 300 is slidably connected to the base plate 10 . Furthermore, the housing 300 and the base plate 10 are slidably connected via a slide rail.

[0033] Furthermore, the vertical walls 12 are in a closed structure connected end to end along the circumferential direction.

[0034] It is understandable that the user can press the housing 300 to switch the state of the magnetic structure.

[0035] According to some embodiments of the present application, the base 1 further includes: a limiting portion, which is provided on the mounting seat 102, and the magnetic portion 2 is movably connected to the limiting portion along the first direction.

[0036] In this embodiment, the base 1 further includes a limiting portion, which is provided on the mounting seat 102 and is used to limit the movement direction of the magnetic portion 2 so that the magnetic portion 2 can move along the first direction driven by the first connecting rod 320 .

[0037] Specifically, the limiting portion includes a guide groove or a limiting column, and the guide groove or the limiting column extends along the first direction.

[0038] like Figure 1As shown, according to some embodiments of the present application, the base 1 further includes: a reinforcement block 14 , which is provided on the outer side wall of the vertical wall 12 , and the reinforcement block 14 is located at both ends of the shell 300 .

[0039] In this embodiment, the base 1 further includes a reinforcing block 14 , which is disposed on the outer side wall of the vertical wall 12 , thereby increasing the strength of the vertical wall 12 and preventing damage to the vertical wall 12 when the housing 300 is pressed.

[0040] In a specific application, when there are two shells 300 , there are two reinforcement blocks 14 , and the shells 300 and the reinforcement blocks 14 are alternately arranged along the circumference of the cavity.

[0041] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the pressing assembly 3 further includes: a reset member 34, which is disposed between the shell 300 and the vertical wall 12. In the first state, the reset member 34 is in a deformed state.

[0042] In this embodiment, the pressing assembly 3 also includes a reset member 34, which can realize the reset of the pressing assembly 3. Specifically, the reset member 34 is arranged between the shell 300 and the vertical wall 12, and in the first state, the reset member 34 is in a deformed state, and then after the shell 300 is released, the reset member 34 restores the deformation, drives the shell 300 away from the magnetic part 2, so that the second connecting rod 302 is away from the magnetic part 2, drives the first end 322 of the first connecting rod 320 away from the magnetic part 2, so that the second end 324 of the first connecting rod 320 is close to the base 1, and then the magnetic part 2 moves downward to the base 1.

[0043] In a specific application, in the second state, the restoration member 34 is in a natural state, that is, an undeformed state.

[0044] Furthermore, one end of the restoration member 34 contacts the housing 300 , and the other end contacts the outer side wall of the vertical wall 12 .

[0045] In the process of switching from the second state to the first state, the shell 300 gradually approaches the vertical wall 12, thereby compressing the reset member 34 and generating deformation energy. After the shell 300 is released, the reset member 34 drives the shell 300 away from the vertical wall 12 through the deformation energy, thereby realizing the reset of the magnetic part 2.

[0046] According to some embodiments of the present application, the reset member 34 includes an elastic member, which is sleeved on the second connecting rod 302 .

[0047] In this embodiment, the reset member 34 includes an elastic member, which is sleeved on the second connecting rod 302 . When the housing 300 moves relative to the vertical wall 12 , the elastic member deforms, thereby achieving the reset of the housing 300 and the magnetic part 2 .

[0048] Specifically, the elastic member includes a spring.

[0049] According to some embodiments of the present application, the second connecting rod 302 and the housing 300 are an integral structure.

[0050] In this embodiment, the second connecting rod 302 and the housing 300 are an integrated structure, which increases the connection strength between the second connecting rod 302 and the housing 300, thereby ensuring that the second connecting rod 302 moves with the housing 300 and drives the magnetic part 2 to move.

[0051] like Figure 1 As shown, according to some embodiments of the present application, the shell 300 is arc-shaped, and the shell 300 is bent toward the magnetic part 2.

[0052] In this embodiment, the housing 300 is arc-shaped and bends toward the magnetic portion 2 , making the magnetic structure more beautiful in appearance.

[0053] Specifically, the vertical wall 12 is annular in shape, and the arc-shaped plate is adapted to the shape of the vertical wall 12 .

[0054] like Figure 1 As shown, according to some embodiments of the present application, the number of pressing components 3 is at least two groups, and the at least two groups of pressing components 3 are arranged on two opposite sides of the magnetic portion 2 along the second direction.

[0055] In this embodiment, at least two groups of pressing components 3 are arranged on opposite sides of the magnetic part 2 along the second direction. In this way, by pressing at least two pressing components 3, the reliability of the movement of the magnetic part 2 can be ensured, thereby facilitating the picking up of the magnetic device.

[0056] In a specific application, there are two groups of pressing components 3 , and the two groups of pressing components 3 are arranged opposite to each other on both sides of the magnetic part 2 .

[0057] According to some embodiments of the present application, the magnetic structure includes a wireless charger.

[0058] In this embodiment, the magnetic structure includes a wireless charger, which can be used to power electronic devices. When charging the electronic device, the magnetic structure is attached to the electronic device for wireless charging. When charging is complete or the wireless charger needs to be separated from the electronic device, the pressing portion 30 is pressed to move the pressing portion 30 closer to the magnetic portion 2, thereby moving the magnetic portion 2 away from the base 1. This moves the magnetic portion 2 away from the electronic device, reducing the attraction between the magnetic portion 2 and the electronic device, and the wireless charger can be easily separated from the electronic device.

[0059] Magnetic devices include electronic devices, vehicle-mounted devices, magnetic pendants, magnetic blackboard erasers, etc. The magnetic structure proposed in this application can be used in conjunction with the above-mentioned magnetic devices.

[0060] Furthermore, the magnetic structure includes electronic device accessories, specifically, the electronic device accessories include a wireless charger or a mobile phone holder, which is used to support the electronic device or power the electronic device.

[0061] Among them, when the magnetic device includes an electronic device, the electronic device includes a mobile phone, a tablet computer, a wearable device, etc.

[0062] In a specific application, the electronic device includes a mobile phone, and the magnetic structure includes a wireless charger. The shell 300 and the second connecting rod 302 are a whole. The shell 300 is limited and fixed by the base 1 of the charger and the through hole 120 of the vertical wall 12, and can only move in two directions: toward the magnetic part 2 and away from the magnetic part 2. The magnetic part 2 is, for example, a magnet. When the shell 300 is held by the hand, the shell 300 and the second connecting rod 302 are forced to move toward the magnet. The end of the first connecting rod 320 close to the second connecting rod 302 moves toward the magnet, and the end close to the magnet moves upward along the first direction (for example, the Z direction). The magnet also moves upward along the Z direction under the drive of the first connecting rod 320. The Z-direction distance between the magnet and the built-in coil of the mobile phone increases, and the magnetic attraction between the wireless charger and the mobile phone decreases, so that the user can easily pick up the charging mobile phone.

[0063] When the wireless charger is removed, the force acting on the shell 300 is removed, and the shell 300 and the second connecting rod 302 are reset under the action of the force of the spring. The end of the first connecting rod 320 close to the second connecting rod 302 moves in the direction away from the magnet, and the end close to the magnet moves downward along the Z direction. The magnet returns to its original state, and the magnetic attraction force remains unchanged when the mobile phone is charged next time.

[0064] Therefore, the opening and closing of the housing 300 can be controlled by holding the wireless charger normally, thereby changing the Z-direction distance between the magnet and the built-in coil of the mobile phone, changing the magnetic attraction between the wireless charger and the mobile phone, and conveniently picking up the charging mobile phone.

[0065] It should be noted that the formula for the magnetic field force of the magnetic pole is: F = mH, where F is the magnetic attraction force, m is the magnetic pole strength, which is inversely proportional to the cube of the distance r, and H is the magnetic field strength. Assuming that the distance between the charger and the built-in magnet of the mobile phone is 2mm, and the magnetic attraction force is 2N; then the distance of the magnet in the charger moves 2mm, and the magnetic attraction force is 1 / 8 of the original, that is, 0.25N. In fact, if the distance between the two magnets reaches a certain level, the magnetic lines of force do not form a good closure, and the magnetic attraction force will drop to a lower level. The shape, size and material of the magnet can be set to achieve a greater effect on the magnetic force by making a small position change. Therefore, the present application realizes the change of the distance between the magnetic part 2 and the mounting base 102 by pressing the component 3, and then realizes the change of the distance between the magnetic part 2 and the mobile phone, so as to facilitate the separation of the mobile phone from the wireless charger.

[0066] The magnetic attraction structure proposed in this application can reduce the magnitude of the magnetic force between the magnet and the attracted object through the normal pressing action of picking up the wireless charger. In the embodiment proposed in this application, the charger and the mobile phone can be separated with one hand, which has the advantage of operational convenience compared to pulling and peeling the mobile phone and the charger with both hands. In addition. The magnetic attraction force can be increased to enable playing with the mobile phone while wirelessly charging, so that the mobile phone and the wireless charger will not fall off during use. This solution can also solve the problem that if the magnetic attraction force of the wireless charger is too large, it will be difficult to separate the charger and the mobile phone at both ends or the charger wire will be broken by pulling alone. This solution does not require the addition of new electronic sensor devices and adds fewer structural devices, reducing the magnitude of the magnetic force between the magnet and the attracted object.
