The utility model adopts a connector to control the on-off of the upper limit switch 43, the lower limit switch 44 and the motor 3, and adopts a 15-hole needle-shaped connector in the embodiment. As shown in fig. 5, S2 corresponds to the lower limit switch 44, and S3 corresponds to the upper limit switch 43.
In addition, the back of the chair cushion 2 provided by the utility model is a curved surface which is matched with the curve of a human body. When the seat is folded, a comfortable leaning space can be provided for passengers. Meanwhile, the overturning seat and the sub-control module used in the system are waterproof, and can be well adapted to daily operation.
The work flow of the electric turnover seat control system provided by the utility model comprises the following steps.
Step S1: and (3) powering on the system, sending an unlocking signal to each sub-control module by the main control module, and starting the motor by a controller in the sub-control module according to the unlocking signal.
Specifically, the master control module is operated by the train cab, and uniformly sends out signals to the sub control modules and receives the signals sent by the sub control modules.
Step S2: the motor drives the rotating assembly to rotate so as to drive the seat cushion to forward overturn, the seat cushion is overturned in place to trigger the upper limit switch, and the upper limit switch controls the motor to stop rotating, so that the seat is unfolded.
Specifically, a sub-control circuit controller is installed in each sub-control module, referring to fig. 5, the upper limit switch correspondingly triggers to open the in-place switch S3, and at this time, the sub-control module controls the motor 3 to power down and stop.
In this step, the current value of the motor 3 is obtained, if the current value is greater than the preset value and the duration is greater than the preset time, the motor 3 drives the rotating assembly 4 to rotate in the opposite direction of the current rotating direction, and the rotating assembly rotates again according to the current direction after rotating in the opposite direction to a certain angle. In this way, the current value of the motor 3 can be obtained in real time or in an irregular manner, so that the state of the motor 3 can be conveniently monitored at any time, and unexpected extrusion accidents in the process of unfolding the seat can be avoided.
The motor 3 drives the rotating assembly 4 to rotate reversely to a certain angle, then enters a standby state, and rotates again according to the current direction after the specified time. If the current value of the motor 3 is still larger than the preset value after the motor 3 rotates again according to the current direction, the duration time is longer than the preset time, and the repetition times are longer than the preset times, the system gives an alarm.
Step S3: the master control module sends out a locking signal to each sub control module, and a controller in the sub control module starts a motor according to the locking signal.
Specifically, the locking signal, namely the corresponding signal of the seat folding action, is still sent by the cab to the operation of the master control module.
Step S4: the motor drives the rotating assembly to rotate so as to drive the chair cushion to reversely overturn, the chair cushion overturns in place to trigger the lower limit switch, and the lower limit switch controls the motor to stop rotating, so that the chair is folded.
In this step, the current value of the motor 3 is obtained, if the current value is greater than the preset value and the duration is greater than the preset time, the motor 3 drives the rotating assembly 4 to rotate in the opposite direction of the current rotating direction, and the rotating assembly rotates again according to the current direction after rotating in the opposite direction to a certain angle.
The motor 3 drives the rotating assembly 4 to rotate reversely to a certain angle, then enters a standby state, and rotates again according to the current direction after the specified time. If the obtained motor current value is still larger than the preset value after the motor rotates again according to the current direction, the duration time is longer than the preset time, the repetition times are longer than the preset times, and the system gives an alarm.
For example, after the master control module sends an unlocking signal, the motor is started, the seat touches an obstacle in the opening process, and the seat cushion cannot be overturned in place. At this time, the motor is prevented from rotating, and a locked-rotor current is generated. The locked rotor current is larger than the normal current of the motor, when the controller of the sub-control module monitors the locked rotor current value and continues for the designated time, the seat is judged to be opened and meets the obstacle, and the motor is controlled to reversely rotate for a certain angle, namely, the seat cushion is turned over towards the stowing direction and stays for a period of time, so that the passenger can remove the obstacle. And then the motor rotates again according to the original rotation direction, and if the locked rotor current value is generated again and exceeds the designated time, the operation is repeated until the seat is opened to touch the upper limit switch. If the number of repeated operations exceeds three, the system judges the alarm, the controller initiates the alarm to the master control module, and the operator checks the fault according to the alarm notification. The process of eliminating the obstacle when the seat is retracted is the same as the above principle, and will not be described again here.
The electric turnover seat control system provided by the preferred embodiment of the utility model comprises turnover seats, sub-control modules and a master control module, wherein each turnover seat is provided with the sub-control module, the sub-control modules control the turnover of the turnover seat, the sub-control modules are electrically connected in parallel, and the sub-control modules are electrically connected with the master control module in series respectively. When a single sub-control module fails, the sub-control modules on other seats are not affected. The sub-control module comprises a motor, a controller and a rotating assembly, wherein the controller controls the motor, and the motor drives the rotating assembly and drives the overturning seat to overturn. The seat can be turned over and folded through centralized control, so that the available space in the vehicle can be adjusted flexibly, and the operation requirements of different time periods can be met.
In the working process of the electric turnover seat control system provided by the preferred embodiment of the utility model, the master control module sends unlocking or locking signals to each sub control module, and a controller in the sub control module starts a motor according to the unlocking or locking signals; the motor drives the rotating assembly to rotate so as to drive the seat cushion to forward overturn, the seat cushion is overturned in place to trigger the upper limit switch, and the upper limit switch controls the motor to stop rotating and the seat is unfolded; or the motor reversely overturns to complete the folding of the seat. Thus, the seats are automatically opened or folded under centralized control, and faults generated among the seats can not affect each other. The motor locked-rotor current value is obtained, the obstacle is judged according to time, an obstacle elimination mechanism is provided, and a prompt is sent to an operator when the obstacle cannot be automatically eliminated. And the humanized design of the system is increased while the centralized operation is performed.
The foregoing is merely illustrative of the preferred embodiments of this utility model, and it will be appreciated by those skilled in the art that variations and modifications may be made without departing from the principles of the utility model, and such variations and modifications are to be regarded as being within the scope of the utility model.
