In cities with high population density, the situation that the bus sliding plug door clamps people frequently occurs at the peak of going to and from work, so the sliding plug door with the anti-clamping function is needed. However, the anti-pinch sliding door on the market has the problems that the control is complex, and more parameters need to be considered by control logic. And the service environment of the sliding plug door is complicated, and the traditional anti-pinch device adopting the modes of detecting a driving device or a rotating shaft and the like is easy to cause misoperation. Therefore, the clamping-prevention sliding door has the advantages of simple control logic, strong operability and high safety.
In one embodiment, there is provided an anti-pinch sliding door, as shown in fig. 1, comprising:
the door is plugged.
A vehicle door driving device.
And the first end of the connecting piece is connected with the sliding plug door, and the second end of the connecting piece is connected with the vehicle door driving device in a sliding manner. The connector is stationary relative to the sliding plug door.
And the magnet is arranged on the second end of the connecting piece.

The vehicle door controller comprises a timer and a signal processor. The signal processor is respectively and electrically connected with the Hall sensor, the vehicle door driving device and the timer.
Specifically, the anti-pinch sliding door comprises a sliding door, a vehicle door driving device, a connecting piece, a magnet, a Hall sensor and a vehicle door controller. And the first end of the connecting piece is connected with the sliding plug door, and the second end of the connecting piece is connected with the vehicle door driving device in a sliding manner and is static relative to the sliding plug door. And the magnet is arranged on the second end of the connecting piece. And the Hall sensor is arranged on a sliding rail in the vehicle door driving device. When the sliding plug door is completely closed, the magnet just contacts with the Hall sensor, and the Hall sensor is triggered to generate a sensing signal. After the door controller receives the sensing signal, the door controller confirms that the door is completely closed. The vehicle door controller comprises a timer and a signal processor, is electrically connected with the vehicle door driving device, and can control the vehicle door driving device to drive the vehicle door to open and close. When the signal processor controls the vehicle door driving device to start to close the door, the closing time of the sliding plug door can be recorded; if the magnet is just contacted with the Hall sensor within the preset door closing time, the Hall sensor is triggered to send a sensing signal to the signal processor, and the signal processor receives the sensing signal and confirms that the vehicle door is completely closed; if the door closing time of the sliding plug door recorded by the timer is greater than the preset door closing time, the signal processor controls the door driving device to stop the door closing action or reopen the door.
In particular, a plug door is a type of door for a passenger car vehicle door. During the opening and closing processes of the sliding plug door, the door leaf performs opening and closing movement along the movement track.

If the induction signal is received within the preset door closing time, the sliding plug door is determined to be normally closed; if the recorded door closing time exceeds the preset door closing time, the signal processor still does not acquire the sensing signal when the sliding plug door is completely closed, and the sliding plug door is determined to be abnormal in door closing. At this moment, the signal processor controls the door driving device to stop closing the door or reopen the door, so as to prevent passengers from being trapped and causing casualties. Alternatively, the timer may be a clock circuit, a delay relay circuit, or a timing circuit provided in the single chip microcomputer.
Wherein, the signal processor is respectively and electrically connected with the Hall sensor, the vehicle door driving device and the timer. Specifically, the signal processor may control the door driving device, thereby driving the opening or closing of the door. The signal processor sends a control signal to control the vehicle door driving device, the timer is controlled to start timing, the sensing signal sent by the Hall sensor is received in real time, and the vehicle door driving device starts to close the door after receiving the signal. If the door closing time recorded by the timer is longer than the preset door closing time, the signal processor judges that the sliding plug door is abnormal in door closing and a door closing obstacle exists, and then the signal processor controls the door driving device to stop the door closing action or reopen the door so as to prevent passengers from being injured or articles from being damaged; if the signal processor receives the induction signal within the preset door closing time, the signal processor judges that the sliding plug door is normally closed.
Based on the above structure, the time from the start of the door closing to the fully closed state is typically within N seconds, for example. The timer starts timing when the sliding plug door starts to be closed, and if the signal processor acquires the complete closing information of the sliding plug door within the preset N + M seconds, the sliding plug door is determined to be normally closed; if the signal processor does not acquire the complete closing information of the sliding plug door within the N + M seconds, the fact that the sliding plug door is closed abnormally is determined, a door closing obstacle exists, and the sliding plug door is controlled to stop the door closing action or reopen the door.
The embodiment of the application has the characteristics of high safety and convenience in operation, and the anti-pinch function is simple in control logic, intuitive in effect and strong in operability. The traditional anti-pinch sliding door is complex, and more parameters need to be considered in control logic. In the embodiment of the application, if the door closing time exceeds the preset door closing time and the signal processor does not receive the sensing signal, it is determined that the sliding plug door is blocked, and then the vehicle door driving device is driven to stop closing the door or reopening the vehicle door, only time parameters need to be considered, and the control logic is simple; and, contact through the magnet that sets up on the hall sensor on the slip track among the door drive arrangement and link up the piece second end and deem the sliding plug door and close completely, the effect is directly perceived, maneuverability is strong, can effectively prevent the maloperation, avoids the passenger to be pressed from both sides, improves the security that the sliding plug door used.
