As further optimization, rubber moccasin is surrounded by the rigid stock.
As further optimization, the system also includes vehicle door status detection circuit, the vehicle door status detection circuit and control Device processed is connected, and the on off state for detecting car door feeds back to controller to limit the running time of anti-clipping system, avoids car door After closing well car door is opened because of erroneous judgement.
As further optimization, the system also includes warning device, and the warning device is connected with controller, in car Door is alarmed when clipping to human body or object.
As further optimization, the controller is used for the result fed back according to infrared detector and pressure sensor feeds back Output control executing agency perform corresponding actions, specifically include:
Controller, if infrared detector, which is detected in car door spatial dimension, object, controls after instruction of closing the door is sent The output control executing agency that device feeds back according to infrared detector stops shutdown action, and reverse drive car door turns on;
Controller, if pressure sensor detects the pressure signal on rigid stock, controls after instruction of closing the door is sent Device is contrasted according to the result that pressure sensor feeds back and standard figures, when be above standard numerical value when, control executing agency stop Only shutdown acts, and reverse drive car door turns on.
As further optimization, the system also includes danger button and on-off circuit, stand-by power supply, and the stand-by power supply leads to Cross on-off circuit connection motor, the danger button connecting valve circuit, for situation about being pressed in danger button, under, it is standby It is that motor is powered with power supply, car door opening is driven, so as to meet emergency evacuation demand.
The beneficial effects of the utility model are:
By setting the situation of infrared detector automatic detection car door spatial dimension, in car door just in closing process, such as Fruit, which detects, object appearance in car door spatial dimension, then controls executing agency to stop shutdown action, and reverse drive car door makes It is opened, so as to greatly reduce the probability of car door collision passenger;
In addition, by the setting of pressure experience device, so as to detect pressure experience situation, by (default with standard figures Value) comparison, judge whether to clip to human body or object, and then control executing agency to stop shutdown action, and reverse drive car Door turns on, and prevents that passenger from being crushed;
By setting on off state feedback circuit, the on off state that can detect car door feeds back to controller to limit anti-pinch The running time of system, car door is opened because of erroneous judgement after avoiding closing of the door good.
Brief description of the drawings
Fig. 1 is the automobile door anti-clamping system structured flowchart in the utility model embodiment;
Fig. 2 is pressure experience device application schematic diagram.
Embodiment
The utility model is directed to a kind of bus door anti-clipping system, prevents passenger body or belongings Clamped by car door, effectively protect the safety of passenger.
Below in conjunction with the accompanying drawings and embodiment is further described to scheme of the present utility model:
As shown in figure 1, the bus door anti-clipping system in the present embodiment, including:Controller, infrared detector, pressure Sense device, executing agency, warning device, vehicle door status detection circuit;
Wherein, control core of the controller as system, for signal, the pressure experience dress fed back according to infrared detector Put the signal of feedback, the signal of vehicle door status detection electronic feedback is calculated, control executing agency execution corresponding actions;This reality By the use of it is new from operating ambient temperature scope is wide, the good MSP430F2131 single-chip microcomputers of compatibility as controller, to adapt to car door The demand of the complicated running environment of anti-clipping system;
Infrared detector is made up of transmitter, the receiver being separately mounted on left and right two columns of car door;Transmitter, Receiver is connected to form infrared ray parallel optical screen by connecting cable and control box, and detectable signal caused by light curtain is by connecting electricity Cable is concentrated in control box and handled by arithmetic core.Therefore, the covering that a plane can be established in car door entrance area is whole The investigative range in car door space, existing object in effective detection range, rapidly feeds back to controller, bristles with anger under controller Order stops closing of the door action, and reverse drive car door turns on, so as to greatly reduce the probability that door knob hits passenger.
Pressure experience device includes pressure experience structure and pressure sensor, and the pressure experience structure is to be arranged at car door The rigid stock 2 being connected at docking port and with door body 1 by hinge 4, it is each in the upper and lower part position of the rigid stock 2 A pressure sensor 3 is provided with, the pressure experience device is used to detect pressure on rigid stock 2, and feeds back to control Device processed;
In arrangements for automotive doors anti-pinch safe practice, mainly solve the problems, such as it is to prevent that personnel's body and belongings from being pressed from both sides Firmly.Whether in this problem, being only concerned has object to be clamped by car door, without concern at what position of car door, and is pressed from both sides The problems such as various characteristics of article etc..So do not consider article by folder portion position, pressure experience position is set in the present embodiment As a rigid stock, pressure sensor is vertically connected with and loaded at car door docking port, outside can rubber coating moccasin and other items Injury caused by when clipping to personnel's body to reduce.When thering is article to be added, strong rod entirety stress, upper and lower pressure is oppressed Force snesor.Upper and lower pressure sensor numerical value is different under such circumstances, and the larger side of optional numerical value is as judge base Standard, contrasted by controller and standard figures, when be above standard numerical value when, control executing agency stops shutdown action, and reversely Driving car door, which turns on, to be avoided crushing passenger.
Safety when can effectively ensure car door opening by the automobile door anti-clamping system of twofold detection and close, but To consider that in some cases, the car door caused by there is a situation where of automobile door anti-clamping system is opened by mistake.Thus, this reality Apply and vehicle door status detection circuit is also provided with example, the on off state for detecting car door feeds back to controller to limit anti-pinch system The running time of system, after car door completely closes, i.e., after car door extends to closed mode, anti-clipping system is resting state, is kept away Exempt from because of erroneous judgement to open car door after closing of the door is good.
In addition, being also provided with warning device in the present embodiment, when car door clips to human body or object, controller is held in control Row mechanism carries out also triggering warning device while corresponding actions, reminds driver to pay attention to by sound, light alarm, tight in order to take into account Evacuation function under anxious state, danger button and on-off circuit, stand-by power supply, the stand-by power supply are also provided with the present embodiment Motor is connected by on-off circuit, the danger button connecting valve circuit, for situation about being pressed in danger button, under, Stand-by power supply is powered for motor, car door opening is driven, so as to meet emergency evacuation demand.When stand-by power supply does not work yet, Car door should be able to be opened to both sides with the strength of ordinary people by force.
