Thus, the safety performance of the hatch 70 is improved.
Specifically, a receiving module 100 for receiving a signal and a transmitting module 200 for transmitting an instruction to each member are provided; the receiving module 100 and the sending module 200 are integrated into a general control program of the door anti-pinch device, and the general control program can send a power supply signal to the infrared detection device 20 of the door through a door 70 opening signal or a door 70 closing signal sent by the control switch 10 in the cockpit so as to drive the infrared detection device 20 of the door to enter a detection working state; and the general control program can send a closing signal to the door pump electromagnetic valve 30 through the detection signal sent by the cabin door infrared detection device 20 so as to close the cabin door 70; and the general control program can send an opening signal to the door pump solenoid valve 30 to open the hatch door 70 when the detection signal sent from the hatch door infrared detection device 20 is turned off. For example, but not limited to, the control switch 10 is a rocker switch disposed in the cockpit, and when the rocker switch is pressed, the control switch 10 sends a door 70 closing signal or a door 70 opening signal. The power supply signal is a high level signal.
When the master control program can always receive the detection signal transmitted by the hatch door infrared detection device 20, the master control program can send a closing signal to the door pump electromagnetic valve 30 after receiving the hatch door 70 closing signal, so that the door pump electromagnetic valve 30 closes the hatch door 70; after the detection signal transmitted from the infrared hatch detection device 20 is received by the general control program, the general control program sends an opening signal to the door pump solenoid valve 30, so that the door pump solenoid valve 30 opens the hatch 70.
In some embodiments, a speed measuring module 300 is further included, the speed measuring module 300 is configured to monitor vehicle speed information, and the sending module 200 is further configured to send an opening signal to the door pump solenoid valve 30 to open the door 70 when the vehicle speed is zero.

For example, but not limited to, the speed measuring module 300 is a circuit module including a speed sensor, the speed sensor is a signal detector in the circuit module, and the speed sensor is communicatively connected to the general control program, so as to be operatively associated with the receiving module 100 and the transmitting module 200. It should be understood that the circuit module is also configured with common electrical components for supporting the long-term action of the speed sensor, such as a circuit switch control element, a power supply, etc., and the connection mode and structure of each electrical component are conventional choices of those skilled in the art, and are not described in detail herein.
In some embodiments, the receiving module 100 is further configured to receive an electrical signal sent by an emergency switch 40 in the cockpit to open or close the door 70.
In this embodiment, when the control switch 10 in the cockpit fails (i.e., the opening or closing of the door 70 cannot be controlled by the control switch 10), the door 70 can be opened or closed by the emergency switch 40. For example, but not limited to, the emergency switch 40 may be an emergency hatch door 70 button, and the emergency hatch door 70 button may directly control the door pump solenoid valve 30 to open or close through the receiving module 100, so that when the vehicle 60 is powered on, the emergency hatch door 70 button is directly pressed to open the door pump solenoid valve 30 and execute an instruction for opening the hatch door 70; pressing the emergency hatch door 70 button again closes the door pump solenoid valve 30 and executes the command to close the hatch door 70.
Referring to fig. 2 to 3, in other embodiments, the door anti-pinch device is further configured with a control module 400. The control module 400 is communicatively connected to the receiving module 100 and the sending module 200; after the receiving module 100 receives a hatch door 70 closing signal or a hatch door 70 opening signal sent by a control switch 10 in a cockpit, the sending module 200 is controlled to send a power supply signal to a hatch door infrared detection device 20 in a luggage compartment; after the receiving module 100 receives the detection signal from the hatch door infrared detection device 20, the control sending module 200 sends a closing signal to the door pump solenoid valve 30 to close the hatch door 70; when the detection signal is turned off, the control transmission module 200 transmits an opening signal to the door pump solenoid valve 30 to open the hatch door 70.
Alternatively, the control module 400 is electrically connected to the receiving module 100 and the transmitting module 200, and the three are disposed in the same circuit, and the receiving module 100 and the transmitting module 200 are respectively connected to the control module 400 in parallel. For example, but not limited to, the control module 400 is a control chip integrating related logic pheromones, the receiving module 100 is a receiving chip integrating related pheromones, and the sending module 200 is a sending chip integrating related pheromones.
Alternatively, the control module 400 may be communicatively connected to an external program such as the cellular phone/computer 500, so as to integrate the internal control logic of the door anti-trap device through the control module 400, and then realize the user side control through the external program such as the cellular phone/computer 500.
In some embodiments, the door anti-trap device is further configured with a speed measurement module 300. The speed measuring module 300 is connected to the control module 400 in a communication manner, and the speed measuring module 300 is configured to monitor vehicle speed information; when the receiving module 100 receives the vehicle speed information that the vehicle speed is zero and is sent from the speed measuring module 300, the control module 400 controls the sending module 200 to send an opening signal to the door pump solenoid valve 30, so as to open the cabin door 70.
Thus, the speed measuring module 300 is electrically connected to the control module 400, and is respectively connected to the control module 400 in parallel with the receiving module 100 and the transmitting module 200, so as to improve the door anti-trap device through the control logic of the door anti-trap device. For example, but not limited to, the tachometer module 300 is a tachometer chip integrated with relevant pheromones.
Referring to fig. 1 to 3, in a second aspect, the present disclosure also provides a hatch door infrared detection device 20, including:
a transmitting unit 21 and a receiving unit 22, which are relatively disposed at preset positions in a luggage compartment of the vehicle 60;
the travel switch 23 is arranged on the rotating shaft 50 of the cabin door 70, and the travel switch 23 is electrically connected with the cabin door anti-pinch device and is used for detecting whether the cabin door 70 is closed; and
the control box 24 is electrically connected with the cabin door anti-pinch device, and when the receiving unit 22 receives the signal sent by the transmitting unit 21, the control box 24 sends a detection signal to the receiving module 100; when the receiving unit 22 cannot receive the signal sent by the transmitting unit 21, the detection signal is turned off.
In this embodiment, the specific structure of the hatch door infrared detection device 20 is optimized. Specifically, a transmitting unit 21 for transmitting a signal, a receiving unit 22 for receiving the signal transmitted by the transmitting unit 21, a control box 24 for receiving the signal transmitted by the receiving unit 22, and a travel switch 23 for detecting whether the hatch door 70 is closed are provided. The above four separate components are combined to form the hatch door infrared detection device 20 in the present embodiment.
In some embodiments, the receiving unit 22 may be an infrared emitting head disposed near the bottom of the door 70. For example, but not limiting of, the IR emitting heads may be positioned 400mm above the bottom of the door 70 and 100mm from the sides of the door 70. Thus, the infrared emission head is prevented from being shielded by the link mechanism of the hatch 70, and the infrared emission head is prevented from being shielded by the luggage. It should be explained that the linkage mechanism of the hatch 70 is a part of the pneumatic control module 400 of the vehicle 60, and is communicated with the door pump solenoid valve 30, and when the door pump solenoid valve 30 is opened, the linkage mechanism of the hatch 70 pushes the hatch 70 to move away from the vehicle 60 under the action of the air pump, so as to open the hatch 70; when the door pump solenoid valve 30 is closed, the linkage mechanism of the hatch door 70 pulls the hatch door 70 to move in a direction close to the vehicle 60, thereby closing the hatch door 70.
Specifically, the infrared emission head adopts a complementary self-excited oscillation circuit as a driving power supply, and the complementary self-excited oscillation circuit is directly added at two ends of an infrared light-emitting diode so as to enable the infrared light-emitting diode to emit infrared beams which are subjected to pulse modulation and have high duty ratio. For example, but not limited to, a single beam of incident light having a wavelength of about 1000nm is used to avoid interference from non-obstacles.
In some embodiments, the receiving unit 22 may be an infrared receiving head disposed at the bottom of the door 70 and at both sides of the door 70 opposite to the infrared emitting head, so as to realize real-time monitoring of the obstacle at the door 70. For example, but not limiting of, the IR receiver head is positioned 400mm above the bottom of the door 70 and 100mm from the side of the door 70. Thus, the infrared receiving head is prevented from being shielded by the link mechanism of the hatch 70, and the infrared receiving head is prevented from being shielded by the luggage.
Specifically, the infrared receiving head comprises an optical lens, an infrared photoelectric tube, an amplification shaping circuit, a power driver and the like.
In some embodiments, the control box 24 disconnects the detection signal sent to the vehicle control module 400 after a first predetermined time period elapses after the receiving unit 22 fails to receive the signal sent by the transmitting unit 21.
In the present embodiment, if it is determined that the pheromone in which the detection signal is turned off is a time during which the receiving unit 22 cannot receive the signal transmitted by the transmitting unit 21 continues for the first predetermined time, it is determined that the detection signal transmitted from the control box 24 to the vehicle control module 400 is turned off. It should be understood that the first predetermined time in the present embodiment is a range of values. Preferably, the first predetermined time is 10 to 60ms. The duration of the first appointed time selected in the time range all belongs to the protection range of the embodiment.
Preferably, the first predetermined time is 40ms.
In other embodiments, the pheromone for determining that the detection signal is disconnected further includes that the receiving unit 22 receives less than 90% of the integrity of the light signal emitted from the transmitting unit, and determines that the detection signal transmitted from the control box 24 to the vehicle control module 400 is disconnected when the first time period is reached.
Specifically, in order to improve the accuracy of detecting the obstacle at the hatch door 70, the pheromone for judging the disconnection of the detection signal is added so that the integrity of the light signal transmitted from the transmitting unit received by the receiving unit 22 is less than 90%, and when the first time period is reached, it is judged that the detection signal transmitted from the control box 24 to the vehicle control module 400 is disconnected.
From above, within the set distance, the infrared emission head emits a light beam, and the infrared receiving head receives the light beam emitted by the infrared emission head or the light beam shielded according to the percentage, and forms a detection signal through the control box 24 and transmits the detection signal to the receiving module 100. When there is no obstruction (i.e., no obstacle), the infrared receiving head receives 100% of the light beam information, and at this time, the control box 24 may form a detection signal and transmit the detection signal to the receiving module 100. When the full shielding rate or the shielding rate reaches 10% or more and the shielding duration reaches the first predetermined time, the control box 24 cannot form a detection signal and cannot transmit the detection signal to the receiving module 100. Thus, the infrared hatch detecting device 20 can monitor the obstacle at the hatch door 70 in real time, and transmit the detected signal to the receiving module 100 or disconnect the transmission of the detected signal.
Referring to fig. 4 and 5, in a third aspect, the present disclosure also provides a vehicle 60 including the door anti-pinch device as described above and the door infrared detection device 20 as described above.
In this embodiment, the specific structure of the door anti-pinch device and the specific structure of the door infrared detection device 20 refer to the above embodiments, and since the vehicle 60 adopts all the technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are at least achieved, and are not repeated herein.
