It is to be understood that other specific arrangements of parts, structures, example devices, systems, and steps may be utilized and structural and functional modifications may be made without departing from the scope of the present invention.

Nothing in this specification should be construed as requiring a specific three dimensional orientation of structures in order to fall within the scope of the invention.
Referring to FIG. 1, an electrical circuit schematic diagram of a door anti-pinch system of the present invention mounted to a side-by-side vehicle door 100 is representatively illustrated. In the exemplary embodiment, the door anti-pinch system of the present invention is applied to an airport ferry vehicle as an example, and further, the anti-pinch control function provided to the side-by-side door 100 of the airport ferry vehicle will be described. Those skilled in the art will readily appreciate that various modifications, additions, substitutions, deletions, or other changes may be made to the embodiments described below in order to utilize the concepts of the present invention in other types of vehicles or other equipment, and still remain within the scope of the principles of the door anti-trap system as taught by the present invention.
As shown in fig. 1, in the present embodiment, the door anti-pinch system according to the present invention can be disposed on an airport ferry vehicle that includes at least a pair of side-by-side doors 100 and a drive mechanism 200. The side-by-side vehicle door 100 mainly includes two door bodies, and for convenience of understanding and explanation, the two door bodies of the side-by-side vehicle door 100 are defined as a first door body 110 and a second door body 120, respectively. The driving mechanism 200 is used for driving the first door 110 and the second door 120 to open and close relatively. On the basis, the anti-pinch system of the vehicle door provided by the invention mainly comprises a light sensing device 310, an acoustic sensing device 320 and a control mechanism. Specifically, the light sensing device 310 and the sound sensing device 320 are respectively disposed on the side-by-side vehicle door 100. The light sensing device 310 can emit sensing light from one of the door bodies to the other door body, so as to measure an optical signal, which can represent the distance between the two door bodies. The acoustic sensing device 320 can emit a sensing acoustic wave from one of the door bodies to the other door body, so as to measure an acoustic signal, which can represent the distance between the two door bodies. The control mechanism is respectively connected to the light sensing device 310, the sound sensing device 320 and the driving mechanism 200 of the airport ferry vehicle, and the control mechanism can control the driving mechanism 200 according to the light signal and the sound signal, so that the anti-pinch control of the open type vehicle door 100 is realized. Based on the above design, when the side-by-side vehicle door 100 starts to close, i.e. for example, when the driver presses the tank door button of the vehicle, i.e. before the two door bodies of the side-by-side vehicle door 100 will be closed by the relative movement from the open position, if the control mechanism does not receive at least one of the optical signal and the acoustic signal, the control mechanism controls the driving mechanism 200 not to work, i.e. the side-by-side vehicle door 100 does not generate the door closing action, so as to wait for the further operation of the driver. Furthermore, during the closing process of the side-by-side vehicle door 100, i.e., during the relative closing process of the two door bodies, when the optical signal disappears and the distance represented by the acoustic signal is smaller than or equal to a set value, or when the acoustic signal disappears (no matter whether the optical signal disappears), the control mechanism controls the driving mechanism 200 to open or stop closing the side-by-side vehicle door 100.
Through the design, the anti-pinch system of the vehicle door can measure the optical signal and the acoustic signal representing the distance between the two door bodies respectively by using the optical sensing device 310 and the acoustic sensing device 320, and control the driving mechanism 200 of the airport ferry vehicle according to the collected optical signal and acoustic signal by using the control mechanism, so that the anti-pinch function of the split vehicle door 100 is realized. Therefore, the vehicle door anti-pinch system provided by the invention can realize an active anti-pinch function, and has the advantages of sensitive response, effective protection, anti-pinch protection modes capable of realizing various different functions, wide application range and the like.
Preferably, as shown in fig. 1, in the present embodiment, the first door 110 has a first side facing the second door 120, and the second door 120 has a second side facing the first door 110. On this basis, the light sensing device 310 may preferably emit sensing light from the first side of the first door 110 to the second side, that is, the light signal measured by the light sensing device 310 represents the distance between the first side and the second side. In other embodiments, the light sensing device 310 can also emit the sensing light from the second side to the first side. In addition, the light sensing device 310 may also emit sensing light from other positions of the first door 110 or the second door 120 to the second door 120 or other positions of the first door 110, and the control mechanism calculates the distance between the first side and the second side, that is, the distance between the first door 110 and the second door 120, according to the distance between the other positions and the first side and the second side and the distance represented by the optical signal.
It should be noted that, two door bodies are kept on the same plane in the opening, closing or opening and closing processes, and the definitions of the pitch, the distance and the like in this specification refer to the pitch and the distance in the horizontal direction on the above-mentioned plane. On the basis, the opening speeds of the two door bodies (i.e. the driving speeds of the driving mechanism 200 for driving the two door body driving parts, such as linear speed or angular speed) can be adjusted to be consistent, and the two door bodies are kept on the same plane after being completely opened.
Preferably, as shown in fig. 1, based on the structure that the first door body 110 has a first side edge and the second door body 120 has a second side edge, in the present embodiment, the acoustic sensing device 320 may preferably emit the sensing sound wave from the first side edge of the first door body 110 to the second side edge, that is, the acoustic signal measured by the acoustic sensing device 320 is characterized by the distance between the first side edge and the second side edge. In other embodiments, the acoustic sensing device 320 can also emit the sensing acoustic wave from the second side to the first side. In addition, the acoustic sensing device 320 may also emit the sensing acoustic wave from another position of the first door 110 or the second door 120 to the second door 120 or another position of the first door 110, and at this time, the control mechanism calculates the distance between the first side and the second side, that is, the distance between the first door 110 and the second door 120, according to the distance between the other position and the first side and the second side and the distance represented by the acoustic signal.

The control mechanism is connected to the infrared receiver 312, and collects the optical signal measured by the infrared receiver 312 through a signal line 340 or wireless transmission. In other embodiments, the infrared transmitter 311 may also be disposed on the second door 120, and the infrared receiver 312 may also be disposed on the first door 110 accordingly. In addition, other types of optical distance measuring devices may be used to replace the infrared emitter 311 and the infrared receiver 312 as the light sensing device 310 of the door anti-pinch system, which is not limited to the embodiment.

The acoustic sensing device 320 can emit a sensing acoustic wave from one of the door bodies to the other door body, so as to measure an acoustic signal, which can represent the distance between the two door bodies. The control mechanism is connected to the light sensing device 310, the sound sensing device 320 and the driving mechanism 200 of the airport ferry vehicle, respectively, and the control mechanism can control the driving mechanism 200 according to the light signal and the sound signal. Based on the above design, during the closing process of the side-by-side vehicle door 100, i.e. during the relative closing process of the two door bodies, when the optical signal disappears and the distance represented by the acoustic signal is smaller than or equal to a set value, or when the acoustic signal disappears (no matter whether the optical signal disappears), the control mechanism controls the driving mechanism 200 to open or stop closing the side-by-side vehicle door 100.
It should be noted herein that the airport ferry vehicles illustrated in the drawings and described in the present specification are but a few examples of the wide variety of airport ferry vehicles that can employ the principles of the present invention. It should be clearly understood that the principles of the present invention are in no way limited to any of the details of the airport ferry vehicle or any of the components of the airport ferry vehicle shown in the drawings or described in this specification.
For example, as shown in fig. 1, in the present embodiment, the driving mechanism 200 of the airport ferry vehicle may include a solenoid valve 240, two sets of cylinders 210 (driving two door bodies respectively), an emergency valve 220, a door air pressure sensor 230 and an associated air supply pipeline.
Based on the above exemplary description, several representative operating scenarios in which the door anti-pinch system of the present invention provides a door anti-pinch function in an airport ferry are described in detail below.
The first situation is as follows: when the driver presses the door closing button, if the CPU controller 330 receives the acoustic signal and the optical signal sent back by the ultrasonic receiver 322 and the infrared receiver 312, the CPU controller 330 does not start the anti-pinch control operation, the door closing magnet of the electromagnetic valve 240 of the door pump is started, and the two door bodies of the split door 100 are closed relatively.
Case two: when the driver presses the door closing button, if the CPU controller 330 does not receive the sound signal sent back by the ultrasonic receiver 322 or the light signal sent back by the infrared receiver 312, the CPU controller 330 starts the anti-pinch control action, controls the electromagnetic valve 240 of the door pump to close the door without starting the door closing magnet, does not close the two door bodies of the split door 100, and waits for the further operation of the driver.
Case three: when the driver presses the door closing button, if the CPU controller 330 receives the acoustic signal and the optical signal sent back from the ultrasonic receiver 322 and the infrared receiver 312, the CPU controller 330 does not start the anti-pinch control operation, and the door closing magnet of the electromagnetic valve 240 of the door pump is started. If a person or an object passes through between the two door bodies during the relative closing process of the two door bodies of the side-by-side vehicle door 100, when the infrared ray is shielded, the ultrasonic wave is not shielded, and the distance represented by the sound signal is greater than a set value (for example, 300mm), the CPU controller 330 does not start the anti-pinch function, and if the distance represented by the sound signal is less than the set value, the CPU controller 330 starts the anti-pinch function.
Case four: when the driver presses the door closing button, if the CPU controller 330 receives the acoustic signal and the optical signal sent back from the ultrasonic receiver 322 and the infrared receiver 312, the CPU controller 330 does not start the anti-pinch control operation, and the door closing magnet of the electromagnetic valve 240 of the door pump is started. If a person or an object passes through between the two door bodies during the relative closing process of the two door bodies of the side-by-side vehicle door 100, when the ultrasonic wave is blocked, the CPU controller 330 starts the anti-pinch control operation regardless of whether the infrared ray is blocked.
For example, when the CPU controller 330 starts the anti-pinch control operation, the specific control flow includes outputting a control signal to the door opening magnet of the electromagnetic valve 240 of the door pump, and the door opening end of the electromagnetic valve 240 of the door pump is started to make the gas in the gas path originally supplying the door closing operation reversely flow to the other end of the cylinder 210, so that the two door bodies of the side-by-side vehicle door 100 move in the opening direction and are opened to the maximum position of the side-by-side vehicle door 100 to wait for the further operation of the driver.
In summary, the anti-pinch system for the vehicle door provided by the invention measures the optical signal and the acoustic signal representing the distance between the two door bodies by using the optical sensing device and the acoustic sensing device, and controls the driving mechanism of the airport ferry vehicle by using the control mechanism according to the collected optical signal and acoustic signal, thereby realizing the anti-pinch function of the split vehicle door. Through the design, the vehicle door anti-pinch system provided by the invention can realize an active anti-pinch function, and has the advantages of sensitive response, effective protection, anti-pinch protection modes capable of realizing various different functions, wide application range and the like.
