Description

Be used for car lighting system fault setting to detect box

Technical field the utility model relates to a be used for car lighting system trouble to set up detection box belongs to automobile inspection technical field.

The internal interactive system of on-off control that does not have to car light system of background art yet, also there is not detection terminal, and car light system trouble is the most common maintenance operation project in the actual vehicle maintenance process, also is the study key of our teaching, and the teacher need simulate in the practice teaching process and set up the trouble, improves student's technical ability, the current mode that sets up the trouble: firstly, line faults (damage of original vehicle lines, line cutting and the like); secondly, artificially damaging the electric equipment or the control unit; and thirdly, the switch is damaged, and the initial state of the vehicle cannot be recovered after the fault is eliminated, so that inconvenience is brought to teaching and the expense of consumable materials for practice is greatly increased for schools.

The invention solves the problem that a teacher sets a light fault in the whole vehicle teaching process, disconnects the original vehicle wiring harness and the switch, and connects the fault setting box into the circuit, so that the teacher can realize the on-off of the circuit by operating the mechanical switch in the fault setting box, finally realize the setting of a fault point, and the fault setting box is internally provided with a test signal point, so that the measurement can be conveniently carried out through the point.

The utility model discloses a technical scheme as follows:

a fault setting detection box for an automobile light system comprises an on-board power grid control unit J519, a fault setting box, a lamp switch E1, fault setting mechanical switches S1, S2, S3 and S4, and test points K1, K2, K3 and K4; the original vehicle wiring harness is disconnected, namely the vehicle-mounted power grid control unit J519 and the vehicle lamp switch E1 are disconnected, the fault setting box is connected into the circuits of the vehicle-mounted power grid control unit J519 and the vehicle lamp switch E1, a T8/1 male pin in the fault setting box is connected with a T3CC/27 female pin, a T8/2 male pin is connected with a T3CC/28 female pin, a T8/3 male pin is connected with a T3CC/29 female pin, a T8/4 male pin in the fault setting box is connected with a T3CC/30 female pin, a T8/5 female pin in the fault setting box is connected with a Ta/1 male pin at the vehicle lamp switch end, a T8/6 female pin is connected with a Ta/2 male pin at the vehicle lamp switch end, a T8/7 female pin is connected with a Ta/3 male pin at the vehicle lamp switch end, a T8/8 female pin is connected with a Ta/4 male pin at the vehicle lamp switch end, and a vehicle lamp switch J83 circuit is formed between the vehicle lamp switch J519 and the vehicle lamp switch E1, the branch circuit is switched on or off by manually setting fault mechanical switches S1, S2, S3 and S4, and after the fault setting is finished, a tester can test the voltage signals of the points through test points K1, K2, K3 and K4 to determine the fault property and train a diagnosis idea.

The utility model has the advantages that: the basic idea of student detection and diagnosis is developed, the practical training cost is greatly saved, the fault setting is convenient, and the service life of the practical training vehicle is prolonged to the maximum extent.

Description of the drawings fig. 1 is a schematic circuit diagram of the present invention;

1-vehicle electrical network control unit J519; 2-fault setting box; 3-failure setting mechanical switch; 4-testing points; 5-vehicle light switch E1.

The fault setting detection box for the automobile lighting system comprises an on-board power grid control unit J5191, a fault setting box 2, a fault setting switch 3, a test point 4 and a lamp switch E15.

The fault setting box 2 is developed by developers, and comprises a mechanical setting switch and a test point, wherein the switch is purchased on the internet, the installation aperture is 12MM, the rated value is 2A, and two gears and two pins are arranged in the setting box; the test point 4 is purchased on the network and has the model of: TELESKY's banana plug; the box is formed by bonding self-made acrylic plates; the fault setting box is internally connected with a switch or a test point through a common lead in a welding mode.

Disconnecting the original vehicle wiring harness, namely disconnecting the vehicle-mounted power grid control unit J519 and the vehicle lamp switch E1, connecting a fault setting box into a circuit of the vehicle-mounted power grid control unit J519 and the vehicle lamp switch E1, connecting a T8/1 male pin in the fault setting box with a T3CC/27 female pin, connecting a T8/2 male pin with a T3CC/28 female pin, connecting a T8/3 male pin with a T3CC/29 female pin, connecting a T8/4 male pin with a T3CC/30 female pin, connecting a T8/5 female pin in the fault setting box with a Ta/1 male pin at the vehicle lamp switch end, connecting a T8/6 female pin with a Ta/2 male pin at the vehicle lamp switch end, connecting a T8/7 female pin with a Ta/3 male pin at the vehicle lamp switch end, connecting a T8/8 female pin with a Ta/4 male pin at the vehicle lamp switch end, a complete closed circuit is formed between the vehicle-mounted power grid control unit J519 and the vehicle lamp switch E1, the circuit of the branch circuit is switched on or off by manually operating the fault setting mechanical switches S1, S2, S3 and S4, and after the fault setting is finished, a detector can test voltage signals of the point through the test points K1, K2, K3 and K4, determine the fault property and train a diagnosis idea.
