Abstract
The utility model provides an integrated form back door switch signal recognition device, includes the normally closed back door switch of one end ground connection, the BCM controller, the door switch signal pilot lamp of being connected with BCM controller signal output, it still includes the back door contact switch who comprises the stationary contact who sets up on the automobile body and the movable contact that sets up on the back car door, wherein, the other end of normally closed back door switch is connected to back door contact switch's stationary contact, and the signal input part of BCM controller is connected to back door contact switch's movable contact. The utility model discloses a set up back door contact switch between automobile body and back door for, need not set up the connecting wire between automobile body and the back door, no matter how big the back door opening degree can not cause because the on-off state indicating action that the broken string brought like this inefficacy. The reliability of the travelling crane is improved.
Description
Technical field
The utility model relates to the automobile electronic system technical field, specifically a kind of integrated form back door on-off signal means of identification.
Background technology
Door contact interrupter generally adopts on automobile, divides two kinds of free-standing door contact interrupter and integrated form door contact interrupters (being integrated in the door lock controller).Door contact interrupter and BCM (Body Control Module, car body controller) controller connects, and is used for indicating the on off state of car door, when car door opening, sends prompting.In the existing structure, the connection lead between door contact interrupter and the BCM controller is arranged in the car door, on the bigger back door of door opening degree, uses said structure to appear at the drop-down disconnection wiring of the excessive situation of door opening degree easily, makes the on off state indicative function lose efficacy.Driving is caused potential danger.
Summary of the invention
The purpose of the utility model is to above-mentioned deficiency a kind of integrated form back door on-off signal means of identification to be provided, and this device can adapt to the bigger back door of aperture, avoids connection lead to be broken.
The utility model is to realize like this; Comprise an end connected to chassis normally closed back door switch, BCM controller, with BCM controller signals mouth bonded assembly door contact interrupter signal lamp; It is characterized in that: it also comprises by being arranged on the break back contact on the vehicle body and being arranged on the back door contact switch that the moving contact on the back car door constitutes; Wherein, The break back contact of said back door contact switch connects the other end of normally closed back door switch, and the moving contact of back door contact switch connects the signal input part of BCM controller.
Said door contact interrupter signal lamp is the LED lamp, and the negative pole of LED lamp connects BCM controller signals mouth, is connected with resistance R 1 between the positive pole of LED lamp and the power supply.
The utility model is through being provided with the back door contact switch between vehicle body and back door; Make; Connection lead need be set between vehicle body and the back car door, the back door aperture is great so can not cause because the on off state indicative function that broken string brings lost efficacy.Improved the reliability of driving.
Description of drawings
Fig. 1 is the functional block diagram of the utility model.
Wherein, 1---normally closed back door switch, 2---BCM controller, 3---back door contact switch, 3.1---break back contact, 3.2---moving contact, 4---vehicle body, 5---back car door, 6---LED lamp.
The specific embodiment
Further specify the utility model below in conjunction with accompanying drawing and embodiment.
Embodiment: comprise an end connected to chassis normally closed back door switch 1, BCM controller 2, with BCM controller 2 signal output part bonded assembly door contact interrupter signal lamps; It also comprises by being arranged on the break back contact 3.1 on the vehicle body 4 and being arranged on the back door contact switch 3 that the moving contact 3.2 on the back car door 5 constitutes; Wherein, The break back contact 3.1 of back door contact switch 3 connects the other end of normally closed back door switch 1; The moving contact 3.2 of back door contact switch 3 connects the signal input part of BCM controller 2, promptly becomes the utility model.
In the technique scheme, said door contact interrupter signal lamp is a LED lamp 6, and the negative pole of LED lamp 6 connects BCM controller 2 signal output parts, is connected with resistance R 1 between the positive pole of LED lamp 6 and the power supply.
The utility model working process is: when back door is opened, because the tailgate switch is a normally closed back door switch 1, so normally closed back door switch 1 breaks off; And because back door separates with vehicle body, so back door contact switch 3 also breaks off, the signal equivalence that is input in the BCM controller 2 is disconnection, and BCM controller 2 outputs signal to LED lamp 6, and the prompting back door is opened, and drives with caution.
Otherwise, when back door is closed, because the tailgate switch is a normally closed back door switch 1, so 1 conducting of normally closed back door switch; And owing to back door combines with vehicle body; So back door contact switch 3 conductings; The signal equivalence that is input in the BCM controller 2 is conducting; Back door closes the two states signal at Men Kai with door and has just produced variation like this, and the BCM controller can be discerned the door contact interrupter signal, and provides corresponding prompting through LED lamp 6.
Claims (2)
1. integrated form back door on-off signal means of identification; Comprise an end connected to chassis normally closed back door switch (1), BCM controller (2), with BCM controller (2) signal output part bonded assembly door contact interrupter signal lamp; It is characterized in that: it also comprises by being arranged on the break back contact (3.1) on the vehicle body (4) and being arranged on the back door contact switch (3) that the moving contact (3.2) on the back car door (5) constitutes; Wherein, The break back contact (3.1) of said back door contact switch (3) connects the other end of normally closed back door switch (1), and the moving contact (3.2) of back door contact switch (3) connects the signal input part of BCM controller (2).
2. integrated form back door on-off signal means of identification according to claim 1; It is characterized in that: said door contact interrupter signal lamp is LED lamp (6); The negative pole of LED lamp (6) connects BCM controller (2) signal output part, is connected with resistance R 1 between the positive pole of LED lamp (6) and the power supply.
