In one embodiment, the magnetic module 20 may be disposed on the fixing member body 30 by embedding.
Specifically, a groove may be formed on the fixing member body 30, the magnetic attraction module 20 is fixedly disposed in the groove, and the surface of the magnetic attraction module 20 exposed from the groove is flush with the surface of the opening of the groove.
In one embodiment, the magnet module 20 may be a permanent magnet made of a material with a wide hysteresis loop, a high coercivity, and a high remanence, such as a rubidium-iron-boron magnet, a samarium-cobalt magnet, and the like. The fixing piece is fixed to the installation position by the cooperation of the permanent magnet and the magnetic absorption piece 1 fixed to the installation position.
Referring to fig. 2 and fig. 3 together, fig. 2 is a cross-sectional view of a magnetic module 20 according to an embodiment of the application along a thickness direction, and fig. 3 is a cross-sectional view of the magnetic module 20 according to an embodiment of the application. In an embodiment of the present application, the magnetic attraction module 20 may include: the magnetic attraction member 5, the magnetic conduction member 2, the electric conduction coil 7 and the magnet 3.
Specifically, the conductive coil 7 is wound on the surface of the fixing member body 30, the magnet 3 is movably arranged between the absorbing member 5 and the magnetic conductive member 2, the magnetic conductive member 2 is exposed from the groove, the absorbing member 5 is arranged in the groove and far away from the magnetic conductive member 2, when the current in the first direction passes through the conductive coil 7, the magnet 3 moves towards the absorbing sheet, and when the current in the opposite direction passes through the conductive coil 7, the magnet 3 moves towards the magnetic conductive member 2.
In one embodiment, the surface of the groove is provided with a casing 4 with a sleeve-shaped structure, and the casing 4 can be made of non-magnetic materials, such as PVC, PC, teflon, etc. The absorbing member 5, the magnetic conductive member 2, and the magnet 3 are disposed in the housing 4.

Referring to fig. 5, fig. 5 is a schematic structural diagram of a demagnetizing state of the magnetic attraction module 20 according to an embodiment of the present application, when the magnet 3 is attracted to the attraction member 5, the demagnetizing state of the magnetic attraction module 20 is the attracting state of the magnetic attraction module 20, and at this time, the magnetic attraction force generated between the magnetic attraction module 20 and the predetermined position is the smallest, so as to facilitate moving the fixing member body 30.
Referring to fig. 6, fig. 6 is a block diagram illustrating a structure of a magnetic attraction module 20 according to an embodiment of the application, and in an embodiment, the magnetic attraction module 20 may further include a control system. The control system is electrically connected with the conductive coil 7 of the magnetic attraction module 20 and is used for controlling the current direction of the conductive coil 7.

It will be appreciated that by providing the power management module 22 in the control system, a charge or discharge management function is implemented for the power module 21 connected to the module, and the voltage output by the power module 21 is adjusted until the operating voltage of the control module 24 is met, in connection with the control module 24.

U1 is a buffer, U2 is an inverter, VT1 and VT4 are turned on when the terminal L and the terminal P are simultaneously 1 (high level), and the current direction of the conductive coil 7YA is a to B (i.e., the first direction current in the embodiment of the present application); when one of the terminal L and the terminal P is 0 (low level), VT2 and VT3 are turned on, and the current direction of the conductive coil 7YA is B to a (i.e., the current opposite to the first direction in the embodiment of the present application). Thus, the current direction in the conductive coil 7YA can be changed by controlling the states of the logic control terminals L and P of the H-bridge circuit, thereby changing the magnetic attraction direction of the magnetic attraction module 20.

When the time relay KT1 delays, the normally closed contact KA2 is opened, the normally open contact KA1 is closed, the path between the end points S to S1 is opened, the intermediate relay KC1 is opened, the contact K5 is opened, the end point P outputs the signal 1, and the magnetic attraction module 20 is in a demagnetized state, so that the fixing effect (attraction between the magnet 3 and the attraction member 5) between the magnetic attraction member 1 can be released.

The protection module 23 is connected to the logic circuit 25 for maintaining the state of the conductive coil 7 passing the current in the first direction under the preset condition.
It can be understood that the protection module 23 is connected with the logic circuit 25, and when detecting that the object connected to the two ends of the housing 4 in the magnetic attraction module 20 is in the preset state, the position of the magnet 3 is fixed according to the current flow direction of the logic circuit 25 corresponding to the preset state, so that the magnet 3 and the preset position are in the adsorption state, and the stability of fixing the magnetic attraction module 20 is improved.
In this embodiment, the preset condition is that the current display panel 51 is in an on state. Note that, the preset condition may be set so that the current display panel 51 is turned off, and the current direction in the conductive coil 7 may be opposite to the first direction.
Specifically, the protection module 23 is connected to the endpoint AP, and the control endpoint AP sends out different high level signals or low level signals according to a preset condition. The first switch K1 and the second switch K2 are connected in series, and are connected in series with a normally closed switch contact K7 of the intermediate relay KC 4. When the signal to the AP end point is 1 (the display panel 51 is not activated), the intermediate relay KC4 controls the normally closed switch contact K7 to be in the closed state while closing the first switch K1 and the second switch K2, and the end point S to the end point S1 is in the on state. Since KC3 and KC1 are in the power-off state at this time, the terminals L and P output the signal 1, the h-bridge driving unit controls the coil current direction from B to a, the electromagnet pole direction of the magnetic attraction module 20 is opposite to the pole direction of the magnet 3, the magnet 3 moves to the side of the attraction piece 5 under the action of the electromagnet to attract the attraction piece 5, and the magnetic attraction module 20 is in the demagnetizing state at this time to unlock the magnetic attraction piece 1. If the endpoint AP signal is 0 (the display panel 51 is started), the intermediate relay KC4 controls the normally closed switch contact K7 to be in an off state, and the operations of the first switch K1 and the second switch K2 are disabled.
Further, the terminal AC may be controlled by a preset program, when the terminal AC outputs a high level, the normally open contact K4 of the relay KC2 is closed, similarly, when the lock switch K3 is pressed, the contact K3 is closed, K3 and K4 are connected in parallel, when one of them is closed, the time relay KT2 is turned on, its normally closed contact KA3 is opened with a delay, K03 and K04 are the sub-contacts of the switch K3 and the normally open contact K4 of the relay, respectively, in synchronization with the actions of K3 and K4, K3 or K4 is closed, the terminals S to S1 are turned on, the intermediate relay KC3 is turned on, the contact K6 is closed, the terminal L outputs a signal 0, the h bridge circuit controls the current direction of the conductive coil 7 to flow from a to B, magnetizing the magnetic conductive member 2 and the magnet 3, and at the same time, adsorbing the magnet 3 on the magnetic conductive member 2. When the time delay of KT2 is reached, the contact KA3 is opened, the terminals S to S1 are opened, the terminals L and P output the signal 1, and the magnetizing is stopped, so that the electric energy in the power module 21 can be effectively saved by intermittently magnetizing the magnetic attraction module 20.
Referring to fig. 9 and fig. 10 together, the switch in the logic circuit 25 may be disposed on the surface of the fixing member, so as to facilitate the user to switch the state of the magnetic module 20.
In an embodiment of the present application, the magnetic attraction module 20 may further include: a switch module 60.
The switch module 60 includes: a first switch set and a second switch set. The first switch set and power module 21 is electrically connected to the conductive coil 7 for maintaining a state of current flowing in the conductive coil 7 in a first direction. The second switch set and power module 21 is electrically connected with the conductive coil 7 for maintaining a state of passing a current in the conductive coil 7 in a direction opposite to the first direction, wherein the first switch set and the second switch set cannot be simultaneously activated.
It will be appreciated that the provision of the switching module 60 in the magnetically attractable module 20 facilitates changing the state of the direction of current flow in the conductive coil 7 by controlling the switching module 60 by operating the first switching group to control the current flow in the conductive coil 7 to be maintained in a first direction or by operating the second switching group to control the current flow in the conductive coil 7 to be maintained in a direction opposite to the first direction.
Further, the second switch group may include: a first switch K1 and a second switch K2. The first switch K1 and the second switch K2 are connected in series.
It can be appreciated that the second switch group includes a first switch K1 and a second switch K2, where the first switch K1 is connected in series with the second switch K2, so that when a user mistakenly activates any one of the first switch K1 and the second switch K2, the second switch group is not activated, thereby improving the security of the fixing member and the articles fixed on the fixing member.
In an embodiment, referring to fig. 1 and 9, fig. 9 is a bottom view of a fixing member according to an embodiment of the application. The first switch K1 and the second switch K2 may be disposed on two sides of the side of the fixing member body 30, so as to prevent a user from touching the switch by mistake and improve the security of the fixing member.
It will be appreciated that if the fixing member is placed on an irregular plane, the foot pad 33 may be further disposed on the surface of the fixing member body 30 near the magnetic attraction member 1, so that the magnetic attraction module 20 can be close to the magnetic attraction member 1 at the installation position, and the fixing effect of the fixing member is improved.
Further, referring to fig. 10, fig. 10 is a top view of a fixing member according to an embodiment of the present application, the first switch set may include a third switch K3, and the third switch K3 may be disposed on an upper surface of the fixing member body 30, so that a user may conveniently start the third switch K3 to fix the fixing member.
