The embodiment of the application also provides a door opening and closing control method of the inner shift door 1, which is realized by the door opening and closing device of the inner shift door 1 in any embodiment. The door opening and closing control method of the inner sliding door 1 comprises the following steps:
determining that the detected signal is a door opening trigger signal or a door closing trigger signal;
when the detected signal is a door opening trigger signal, the first driving component 2 and the second driving component 3 are controlled to act, so that the first end of the movable door 11 of the inner door 1 moves along the first guide rail 12 towards the direction approaching the second guide rail 13, and the second end of the movable door 11 moves along the second guide rail 13 towards the direction away from the first guide rail 12, so as to open the door;
when the detected signal is a door closing trigger signal, the first driving assembly 2 and the second driving assembly 3 are controlled to act, so that the first end of the movable door 11 of the inner door 1 moves along the first guide rail 12 in a direction away from the second guide rail 13, and the second end of the movable door 11 moves along the second guide rail 13 in a direction close to the first guide rail 12, so as to close the door.
In the method, the control module 71 firstly determines whether the detected signal is a door opening trigger signal or a door closing trigger signal, and if the detected signal is the door opening trigger signal, the first driving assembly 2 and the second driving assembly 3 are controlled to act so as to open the movable door 11 of the inner door 1; if the detected signal is a door closing trigger signal, the first driving unit 2 and the second driving unit 3 are controlled to operate, so that the movable door 11 of the inner door 1 is closed.
In some exemplary embodiments, the detected signals include a position signal of the first linear motor mover 22 of the first drive assembly 2 and a position signal of the second linear motor mover 32 of the second drive assembly 3; and/or the detected signal comprises a detected signal of the environmental information.
The detected signals include the position signal of the first linear motor mover 22 of the first drive assembly 2 and the position signal of the second linear motor mover 32 of the second drive assembly 3. If the first position sensor 4 near the second guide rail 13 detects that the position of the first linear motor mover 22 changes and the first linear motor mover 22 moves in the direction away from the second guide rail 13, the detected position signal of the first linear motor mover 22 is a door closing trigger signal; if the second position sensor near the first rail 12 detects that the position of the second linear motor mover 32 is changed from 5a to the second linear motor mover 32 and the second linear motor mover 32 moves in a direction away from the first rail 12, the detected position signal of the second linear motor mover 32 is a door opening trigger signal.
When the first sensor 72 detects that the temperature, humidity or pressure of the external environment (such as a shower room) is too high and exceeds a preset range, the control module 71 determines that the detection signal of the first sensor 72 is a door opening trigger signal, and controls the first driving assembly 2 and the second driving assembly 3 to work, so that the movable door 11 is opened, and automatic door opening ventilation is realized. When the first sensor 72 detects that the temperature, humidity or pressure of the external environment is within the preset range, the control module 71 determines that the detection signal of the first sensor 72 is a door closing trigger signal, and controls the first driving assembly 2 and the second driving assembly 3 to work, so that the movable door 11 is closed.
In some exemplary embodiments, when the detected signal is a door opening trigger signal, the step of controlling the first driving assembly 2 and the second driving assembly 3 to act includes:
the plurality of second linear motor stators 31a-31c of the second driving assembly 3 are controlled to sequentially operate from the direction close to the first guide rail 12 to the direction far away from the first guide rail 12, and the second linear motor mover 32 is driven to push the movable door 11 in the door opening direction until the movable door 11 moves to the door opening state;
when the second linear motor stator 31c far from the first guide rail 12 is operated, the first linear motor stator 21 of the first driving assembly 2 is controlled to operate, and the first linear motor mover 22 is driven to push the movable door 11 in the door opening direction.
During the door opening process, the plurality of second linear motor stators 31a to 31c of the second driving assembly 3 sequentially operate in the order from the direction approaching the first rail 12 to the direction separating from the first rail 12 (i.e., in the order of the second linear motor stator 31a→the second linear motor stator 31b→the second linear motor stator 31 c), so that the plurality of second linear motor stators 31a to 31c sequentially provide the driving force to the second linear motor mover 32 to move the movable door 11 to the door opening state.
When the second linear motor stator 31c far from the first guide rail 12 is operated, the first linear motor stator 21 of the first driving assembly 2 is controlled to operate simultaneously, and the first linear motor mover 22 is driven to push the movable door 11 in the door opening direction. Specifically, according to the detection signal of the second position sensor 5c far from the first guide rail 12, it is obtained that the first linear motor mover 22 starts to enter the action range of the first linear motor stator 21, and at this time, the first linear motor stator 21 and the second linear motor stator 31c work cooperatively to push the first linear motor mover 22 and the second linear motor mover 32 respectively.
In some exemplary embodiments, the second linear motor mover 32 is in a constant speed operation stage when the second linear motor mover 32 is moved to be simultaneously driven by the adjacent two second linear motor stators 31b and 31c far from the first guide rail 12 during the opening of the movable door 11;
before the uniform speed operation stage, the second linear motor mover 32 is in the acceleration operation stage;
after the constant speed operation phase, the second linear motor mover 32 is in the deceleration operation phase.
In the door opening process of the movable door 11, the second linear motor mover 32 is in an acceleration operation stage under the independent driving of the second linear motor stator 31a, under the common driving of the second linear motor stator 31a and the second linear motor stator 31b, and under the independent driving of the second linear motor stator 31 b; the second linear motor mover 32 is in a constant speed operation stage under the common drive of the second linear motor stator 31b and the second linear motor stator 31 c; the second linear motor mover 32 is in a deceleration operation stage under the separate driving of the second linear motor stator 31 c.
In some exemplary embodiments, when the detected signal is a door closing trigger signal, the step of controlling the actions of the first driving assembly 2 and the second driving assembly 3 includes:
The first linear motor stator 21 of the first driving assembly 2 is controlled to work, and the first linear motor rotor 22 is driven to push the movable door 11 in the door closing direction;
when the movable door 11 moves to an included angle alpha (see fig. 2) between the movable door and the first guide rail 12 and is in a preset angle range, controlling a plurality of second linear motor stators 31a-31c of the second driving assembly 3, wherein the second linear motor stators 31c far away from the first guide rail 12 start to work, and driving the second linear motor mover 32 to push the movable door 11 in the door closing direction;
the other second linear motor stators 31a and 31b of the second driving assembly 3 are controlled to sequentially operate in the order from the direction away from the first rail 12 to the direction close to the first rail 12 (i.e., in the order of the second linear motor stator 31b→the second linear motor stator 31 a), and the second linear motor mover 32 is driven to push the movable door 11 in the door closing direction until the movable door 11 moves to the door closing state.
In the door closing process, the first linear motor stator 21 works to drive the first linear motor rotor 22 to push the movable door 11 in the door closing direction; when the included angle α between the movable door 11 and the first rail 12 is within the preset angle range, the plurality of second linear motor stators 31a to 31c of the second driving assembly 3 are controlled to start to operate, and the plurality of second linear motor stators 31a to 31c sequentially operate in the order from the direction away from the first rail 12 to the direction close to the first rail 12 (i.e., in the order of the second linear motor stator 31c→the second linear motor stator 31b→the second linear motor stator 31 a), so that the plurality of second linear motor stators 31a to 31c sequentially provide the driving force to the second linear motor mover 32 to move the movable door 11 to the door-opening state.
For the right-angle internal moving door 1, when the movable door 11 is in a door opening state, the included angle alpha between the movable door 11 and the first guide rail 12 is close to 75 degrees, if the second linear motor stator 31c far away from the first guide rail 12 starts to work in the initial stage of door closing, the thrust provided by the second linear motor rotor 32 to the movable door 11 enables a large extrusion component force to be generated between the movable door 11 and the first guide rail 12, so that the friction force between the movable door 11 and the first guide rail 12 is large, and the first linear motor rotor 22 is not easy to drive the first end of the movable door 11 to move. Therefore, when the angle between the movable door 11 and the first rail 12 is within the preset angle range, the second linear motor stator 31c, which is far from the first rail 12, starts to operate and operates simultaneously with the first linear motor stator 21.
In some exemplary embodiments, the predetermined angle range is 45 ° -55 °. Of course, the preset angle range is not limited to 45 ° -55 °, and can be adjusted as desired.
In some exemplary embodiments, the second linear motor mover 32 is switched from the acceleration operation stage to the deceleration operation stage when the second linear motor mover 32 moves to be individually driven by a middle one of the at least three second linear motor stators 31a to 31c during the closing of the movable door 11.
During the closing of the movable door 11, the second linear-motor mover 32 is switched from the acceleration operation stage to the deceleration operation stage when the second linear-motor mover 32 is moved to be driven by the second linear-motor stator 31b alone. Namely, during the closing process of the movable door 11, the first linear motor mover 22 and the second linear motor mover 32 are in the acceleration operation stage under the single drive of the first linear motor stator 21, under the common drive of the first linear motor stator 21 and the second linear motor stator 31c, under the single drive of the second linear motor stator 31c, and under the common drive of the second linear motor stator 31c and the second linear motor stator 31 b; the second linear motor mover 32 is in a deceleration operation stage under the separate driving of the second linear motor stator 31b, under the common driving of the second linear motor stator 31b and the second linear motor stator 31a, and under the separate driving of the second linear motor stator 31 a.

6. when the second linear motor mover 32 moves to the single coverage area of the second linear motor stator 31c, and the control module 71 calculates that the first linear motor mover 22 starts to enter the coverage area of the first linear motor stator 21 according to the position change signal detected by the second position sensor 51c (the second position sensor 51c corresponds to the second linear motor stator 31 c) mounted on the second linear motor stator 31c, the first linear motor stator 21 and the second linear motor stator 31c work cooperatively to push the first linear motor mover 22 and the second linear motor mover 32 respectively, and at this time, the first linear motor mover 22 and the second linear motor mover 32 operate at a reduced speed, so that the movable door 11 operates at a reduced speed;
7. When the movable door 11 moves to the door opening stop position (i.e., is in the door opening state), the first linear motor mover 22 moves to the detection range of the first position sensor 4 mounted on the first linear motor stator 21 (the first position sensor 4 corresponds to the first linear motor stator 21), and the control module 71 confirms the stop position and completes the door opening drive.
During the door opening process, the movable door 11 gradually changes from the door-closed state shown in fig. 11 (b 1) to the door-open state shown in fig. 11 (b 5).
The door closing control method of the inner moving door 1 comprises the following steps:

2. the first linear motor rotor 22 pushes the movable door 11 to move towards the door closing direction under the action of the first linear motor stator 21, meanwhile, the second position sensor 51c mounted on the second linear motor stator 31c starts to detect a position change signal, the signal is collected to the control module 71, and the position and speed data of the movable door 11 are obtained after processing.

6. when the second linear motor mover 32 moves to the single coverage area of the second linear motor stator 31b, the second linear motor mover 32 is switched from the acceleration state to the deceleration state, and the movable door 11 approaches to the door closing stop position;
7. when the second linear motor mover 32 is operated to the coverage areas of the second linear motor stator 31b and the second linear motor stator 31a, the second linear motor mover 32 is continuously decelerating;
8. When the second linear motor mover 32 moves to the single coverage area of the second linear motor stator 31a, the second linear motor stator 31a decelerates the second linear motor mover 32 to a stop, and stops when braking, at this time, one end of the first linear motor mover 22 contacts with the cushion rubber pad to be a stable door closing stop position, and the movable door 11 is in a door closing state.
