In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 9, an embodiment of the present invention discloses an opening and closing assembly, which is applied to an electronic device having a first body 100 and a second body 200, wherein the first body 100 and the second body 200 can be opened and closed by relative movement, for example, a display end of a notebook computer is used as the first body 100, a system end is used as the second body 200, and the display end can be pivoted relative to the system end to form an opened state and a closed state; for another example, in the electronic device that can receive the keypad by pushing and pulling, the keypad is used as the first body 100, and the first body 100 can be received in the second body 200 or extended from the second body 200 by pushing and pulling. The opening and closing assembly of the present invention comprises: the magnetic switch comprises a first magnet 10, a second magnet 20, an actuator and a control button, wherein the first magnet 10 is arranged on a first body 100, the second magnet 20 is arranged on a second body 200, the actuator is used for driving the second magnet 20 to move so that the second magnet 20 can move relative to the first magnet 10, the second magnet 20 can form a first state of attraction with the first magnet 10 and a second state of attraction release through movement, and the control button controls the actuator so that the actuator drives the second magnet 20 to switch between the first state and the second state.
It should be noted that: the first configuration of the second magnet 20 described above should be understood as: the spatial configuration of the second magnet 20, for example, the position, angle, etc. of the second magnet 20 relative to the first magnet 10, is the spatial configuration of the second magnet 20 when the second magnet 20 and the first magnet 10 are attracted by magnetic force, and the second magnet 20 and the first magnet 10 are opposite in polarity when the second magnet 20 is in the first configuration. Accordingly, the second form of the second magnet 20 described above should be understood as: when the second magnet 20 is not attracted to the first magnet 10, the second magnet 20 is in a spatial form, for example, a position, an angle, or the like of the second magnet 20 with respect to the first magnet 10, and when the second magnet 20 is in the second form, the second magnet 20 is in a homopolar opposition to the first magnet 10 or there is no magnetic force between the second magnet 20 and the first magnet 10.
According to the above, when the first body 100 and the second body 200 are in the closed state, the control button controls the actuator to drive the second magnet 20 to switch between the first state and the second state. When a user needs to keep the first body 100 and the second body 200 in the closed state, the actuator drives the second magnet 20 to move from the second state to the first state by operating the control button, and the first magnet 10 and the second magnet 20 generate magnetic attraction due to opposite poles, so that the first body 100 and the second body 200 are kept in the attraction state; when a user needs to switch the first body 100 and the second body 200 from the closed state to the open state, the actuator drives the second magnet 20 to move from the first state to the second state by operating the control button, and the first magnet 10 and the second magnet 20 are not attracted, so that the first body 100 and the second body 200 can be easily opened.
The opening and closing assembly of the invention switches the two bodies under two states of attraction and attraction release by controlling the relative movement of the two magnets. When the electronic device is not in use, the first body 100 and the second body 200 are kept in the closed state by the attraction of the two magnets, and when the electronic device needs to be opened, the first body 100 and the second body 200 are released from the attraction, so that the electronic device can be easily opened.
The second magnet 20 may move relative to the first magnet 10 in two ways: one is that the second magnet 20 rotates relative to the first magnet 10; the other is that the second magnet 20 moves relative to the first magnet 10.
In a preferred embodiment of the present invention, as shown in fig. 1 to 4, an actuator (not shown) is used to drive the second magnet 20 to rotate so as to rotate the second magnet 20 relative to the first magnet 10, and the second magnet 20 is rotated to switch between a first configuration and a second configuration, in which the first configuration is a first angular configuration in which the second magnet 20 is opposite to the first magnet 10 in an opposite polarity, and the second configuration is a second angular configuration in which the second magnet 20 is opposite to the first magnet 10 in an opposite polarity. In the present embodiment, as shown in fig. 1 and 2, the first magnet 10 and the second magnet 20 may be both magnets of an integrated structure, and the two opposite sides of the magnets of the integrated structure respectively have only N pole and S pole, and when the second magnet 20 is rotated to the first angular configuration, as shown in fig. 1, the N pole and the S pole of the first magnet 10 are opposite or the S pole and the N pole of the second magnet 20 are opposite, so that magnetic attraction is generated between the first magnet 10 and the second magnet 20; when the second magnet 20 rotates to the second angular configuration, as shown in fig. 2, the first magnet 10 and the second magnet 20 have two N poles opposite to each other or two S poles opposite to each other, so that a magnetic repulsion force is generated between the first magnet 10 and the second magnet 20. In the present embodiment, the first magnet 10 and the second magnet 20 may be both magnets of a combined structure, specifically, as shown in fig. 3 and 4, each of the first magnet 10 and the second magnet 20 is formed by arranging a plurality of magnet segments 30 in a word, and opposite poles of two adjacent magnet segments 30 are oriented in the same direction, that is, if one of the magnet segments 30 of the first magnet 10 facing the second magnet 20 is S-pole, the adjacent magnet segments 30 on two sides of the magnet segment 30 facing the second magnet 20 are N-pole. In this way, when the second magnet 20 rotates to the first angular configuration, as shown in fig. 3, the magnet segments 30 of the second magnet 20 are opposite to the opposite poles of the magnet segments 30 of the first magnet 10 corresponding to one another, so that the magnetic attraction is generated between the magnet segments 30 of the first magnet 10 and the magnet segments 30 of the second magnet 20 corresponding to one another; when the second magnet 20 rotates to the second angular configuration, as shown in fig. 4, the magnetic poles of the magnet segments 30 of the second magnet 20 are opposite to the magnetic poles of the one-to-one corresponding magnet segments 30 of the first magnet 10, so that the magnetic repulsion is generated between the first magnet 10 and the one-to-one corresponding magnet segments 30 of the second magnet 20.
In a preferred embodiment of the present invention, as shown in fig. 5 to 7, the actuator is used to drive the second magnet 20 to move, and the second magnet 20 is moved to switch between the first state and the second state. In the present embodiment, the first position is a position in which the second magnet 20 is opposite to the first magnet 10 in opposite polarity, and the second position is a position in which the second magnet 20 is opposite to the first magnet 10 in the same polarity or the second magnet 20 is away from the first magnet 10 to lose the magnetic force with the first magnet 10. In the present embodiment, each of the first magnet 10 and the second magnet 20 may be a magnet (not shown in the drawings) of an integrated structure, and each of two opposite sides of the magnet of the integrated structure has only an N pole and an S pole, and when the actuator drives the second magnet 20 to move, so that the second magnet 20 and the first magnet 10 can generate mutual magnetic force, and the N pole and the S pole of the first magnet 10 and the second magnet 20 are opposite or the S pole and the N pole of the first magnet 10 and the S pole of the second magnet 20 are opposite, that is, when the second magnet 20 moves to the first position configuration, a magnetic attraction force is generated between the first magnet 10 and the second magnet 20; when the actuator drives the second magnet 20 to move and the distance between the second magnet 20 and the first magnet 10 is far away from each other, so that the two magnets cannot generate mutual magnetic force, that is, when the second magnet 20 moves to the second position configuration, the magnetic attraction between the two magnets is released. In the present embodiment, as shown in fig. 5 to 7, the first magnet 10 and the second magnet 20 may also be both magnets of a combined structure, specifically, the first magnet 10 and the second magnet 20 are both formed by arranging a plurality of magnet segments 30 in a word, and opposite magnetic poles of two adjacent magnet segments 30 are oriented in the same direction, that is, if one of the magnet segments 30 of the first magnet 10 facing the second magnet 20 is S-pole, the adjacent magnet segments 30 on both sides of the magnet segment 30 facing the second magnet 20 are N-pole. In the present embodiment, the specific method for moving the second magnet 20 from the first position configuration to the second position configuration is as follows: driving the second magnet 20 to move in the arrangement direction of the magnet segments 30 by an actuator, wherein the moving distance is an odd multiple of the length of the magnet segments 30, so that each magnet segment 30 of the second magnet 20 moves from opposite polarity to each magnet segment 30 of the first magnet 10 to the same polarity to each magnet segment 30 of the second magnet 20 to each magnet segment 30 of the first magnet 10; the specific method of moving the second magnet 20 from the second position configuration to the first position configuration is: the actuator is caused to drive the second magnet 20 to move in the direction in which the magnet segments 30 are arranged by an odd multiple of the length of the magnet segments 30, so that the magnet segments 30 of the second magnet 20 are respectively moved from being in opposition with the magnet segments 30 of the first magnet 10 to being in opposition with the magnet segments 30 of the second magnet 20 being in opposition with the magnet segments 30 of the first magnet 10. Therefore, in the present embodiment, the stroke of the actuator driving the second magnet 20 should be an integer multiple of the length of the magnet segment 30.
There are various configurations that can switch the second magnet 20 between the first position form and the second position form. In a preferred embodiment of the present invention, as shown in fig. 5 and 6, a motor 41 is used as an actuator, and the opening and closing assembly further includes a strip-shaped mounting plate 44, a nut 42 and a lead screw 43.

In this way, the motor 41 drives the lead screw 43 to rotate reciprocally by rotating repeatedly to drive the nut 42 to move reciprocally to drive the second magnet 20 to switch between the first position and the second position, wherein the control button is used for controlling the on/off and the forward/reverse rotation of the motor 41 at the same time. For example, when the second magnet 20 is in the first position form, the control button is touched, the motor 41 is started and rotated in the rotation direction in which the second magnet 20 is moved to the second position form, and after the second magnet 20 is moved by an odd number times the length of the magnet segment 30, the control button controls the motor 41 to stop rotating, at which time, as shown in fig. 6, the second magnet 20 is moved to the second position form, when the control button is pressed again, the motor 41 is started again and rotated in the reverse direction, and after the second magnet 20 is moved by an odd number times the length of the magnet segment 30, the control button controls the motor 41 to stop rotating, at which time, as shown in fig. 5, the second magnet 20 is moved to the first position form.
In a preferred embodiment of the present invention, as shown in fig. 7, the actuator is a memory metal 51, and the opening and closing assembly further includes a pulling rope 52, a tension spring 55, a strip-shaped mounting plate 54, a strip-shaped moving body 56, and a pulley 53.
