Abstract
The utility model discloses a passenger door anti-pinch system of a car. The passenger door anti-pinch system of the car comprises an infrared emitting device and an infrared receiving device which are installed at corresponding positions of the two sides of a passenger door, wherein a normally closed contact of the infrared receiving device is connected to a coil power circuit of a door-closing relay in series, a normally open contact of the infrared receiving device is connected to a coil power circuit of a door-opening relay in series, one end of a normally open contact of the door-closing relay is connected with a door-closing static contact of a passenger door switch, the other end of the normally open contact of the door-closing relay is grounded through a door-closing driving coil of a door pump solenoid valve, one end of a normally open contact of the door-opening relay is connected with a power supply, the other end of the normally open contact of the door-opening relay is connected with a door-opening static contact of the passenger door switch and is grounded through a door-opening driving coil of the door pump solenoid valve, and a movable contact of the passenger door switch is connected with the power supply. The passenger door anti-pinch system of the car has the advantages of safely and reliably preventing passengers from being clamped and pinched by the passenger door.
Description
Technical field
The utility model relates to passenger vehicle, especially relates to car occupant door anti-clipping system.
Background technology
Stipulate according to " GB13094-2007 passenger vehicle structural safety technology " GB: " structure of every fan dynamic Control passenger doors and control system should make passenger at closing time, are not injured or clamp by car door ".Current driving force control passenger doors is all to utilize passenger doors clamp prevention controller, detect and be issued to from the instruction of closing the door the duration (5 seconds) that passenger doors is closed completely, if after 5 second time, passenger doors is not closed (courtesy lamps is also being lighted) completely, and controller sends instruction and reopens passenger doors.But this time period (5 seconds) the inner passenger who detects in control system may be clamped or crush by the passenger doors that will close, even if at this moment reopen passenger doors, security incident also occurs again.
Summary of the invention
The utility model object is to provide a kind of car occupant door anti-clipping system.
For achieving the above object, the utility model is taked following technical proposals:
Car occupant door anti-clipping system described in the utility model, comprises the infrared launcher and the infrared receiving device that are arranged on corresponding position, passenger doors both sides; The constant close contact of described infrared receiving device is series in the coil power circuit of closed relay, and the constant open contact of infrared receiving device is series in the coil power circuit of the relay that opens the door; Constant open contact one end of described closed relay is connected with the stationary contact of closing the door of passenger doors switch, and the other end is by the drive coil ground connection of closing the door of door pump electromagnetic valve; Constant open contact one end of the described relay that opens the door is connected with power supply, and the other end is connected with the stationary contact that opens the door of passenger doors switch and by the drive coil ground connection of opening the door of door pump electromagnetic valve; The movable contact of passenger doors switch is connected with power supply.
The utility model advantage is to realize and prevents that safely and reliably passenger from being clamped by passenger doors.Because passenger has stopped the infrared rays between emitter and receiving system in the time getting on the bus or get off, at this moment passenger doors anti-clipping system is opened automatically, the constant close contact of infrared receiver inside disconnects, constant open contact closure, the closed relay being connected with constant close contact returns to normal because of dead electricity, and the constant open contact of closed relay disconnects, and passenger doors is closed gate control circuit and is disconnected, even if at this moment driver and conductor supresses passenger doors closing switch, passenger doors also can not be moved.Simultaneously due to the constant open contact closure of infrared receiver inside, the constant open contact action of the relay that opens the door, the passenger doors circuit that opens the door is connected, the passenger doors electromagnetic valve work that opens the door, passenger doors is opened, and guarantees to prevent that passenger from being crushed.
Accompanying drawing explanation
Fig. 1 is the circuit theory schematic diagram of the utility model embodiment.
The specific embodiment
As shown in Figure 1, car occupant door anti-clipping system described in the utility model, comprises the infrared launcher 1 and the infrared receiving device 2 that are arranged on corresponding position, passenger doors both sides; The constant close contact 3 of described infrared receiving device 2 is series in coil 5 power circuits of closed relay 4, and the constant open contact 6 of infrared receiving device 2 is series in coil 8 power circuits of the relay 7 that opens the door; Constant open contact 9 one end of described closed relay 4 are connected with the stationary contact 10 of closing the door of passenger doors switch, and the other end is by drive coil 12 ground connection of closing the door of door pump electromagnetic valve 11; Constant open contact 13 one end of the described relay 7 that opens the door are connected with power supply, and the other end is connected with the stationary contact 14 that opens the door of passenger doors switch and by drive coil 15 ground connection of opening the door of door pump electromagnetic valve 11; The movable contact 16 of passenger doors switch is connected with power supply.
