Background technology
Prior art does not also have car cleaning device durability test device, can not carry out endurancing to the car cleaning device, therefore can not examine the reliability of car cleaning device.
The utility model content
The car cleaning device durability test device that the utility model provides must not carry out endurancing to the car cleaning device to separate, and can not examine car cleaning device reliability problems.
The technical solution of the utility model:
The utility model provides a kind of car cleaning device durability test device, and described test unit comprises air switch, the time relay, A.C. contactor, D.C. regulated power supply sum counter.
Wherein, the two ends of the solenoid of the described time relay are connected to the alternating current 220V power supply by described air switch, the input terminal of a pair of normally closed contact of this time relay links to each other with an end of this time relay solenoid, and the outlet terminal of a pair of normally closed contact of the described time relay is connected to the other end of described time relay solenoid by the solenoid of described A.C. contactor.
The input end of described D.C. regulated power supply is connected to the alternating current 220V power supply, its dc output end positive pole is connected to an end of car cleaning device motor by a pair of normally opened contact of described A.C. contactor, and the other end of described car cleaning device motor is connected to the negative pole of described D.C. regulated power supply dc output end.The two ends of a pair of normally opened contact of described A.C. contactor are connected respectively on the described counter.Described counter is used for the stored count to the closed number of times of described A.C. contactor normally opened contact.Thereby control the break-make of described scrubber motor by the action that the described time relay is controlled described A.C. contactor normally opened contact.
Adopt this test unit to carry out endurancing to the car cleaning device, the unfailing performance of accurate testing automobile scrubber, the utility model is simple in structure, easy to manufacture, Operation and maintenance convenient, and the utility model is suitable for the automobile that scrubber is housed.
Description of drawings

Embodiment
Fig. 1 is a car cleaning device durability test device structural drawing, and in Fig. 1, car cleaning device durability test device is made up of the time relay 1, air switch 2, D.C. regulated power supply 3, A.C. contactor 4 sum counters 5.
The two ends of the time relay 1 solenoid are connected to the alternating current 220V power supply by air switch 2, the input terminal of a pair of normally closed contact of the time relay 1 links to each other with an end of this time relay solenoid, and the outlet terminal of a pair of normally closed contact of the time relay 1 is connected to the other end of the time relay 1 solenoid by the solenoid of A.C. contactor 4.
The input end of D.C. regulated power supply 3 is connected to the alternating current 220V power supply, its dc output end positive pole is connected to an end of the motor 6 of car cleaning device 7 by a pair of normally opened contact K1 of A.C. contactor 4, and the other end of the motor 6 of car cleaning device 7 is connected to the negative pole of D.C. regulated power supply 3 dc output ends; The two ends of a pair of normally opened contact K2 of A.C. contactor 4 are connected respectively to counter 5.
In this device, A.C. contactor 4 is for having the A.C. contactor of normally opened contact more than two pairs, and D.C. regulated power supply 3 is the common D.C. regulated power supply that can satisfy the scrubber electric moter voltage, and the time relay 1 is for having the time relay of circulation time-delay.
Fig. 2 is a car cleaning device durability test device schematic diagram; according to the requirement of " scrubber technical conditions " endurancing, scrubber is installed on the testing table by the real vehicle simulation, water is cooked cleaning fluid work 5S; shutting down 25S is the one action circulation, does 25000 cyclic tests.
Before the test, the element of car cleaning device durability test device is contained in the control box 8, each element is connected with the wiring requirement of power lead by Fig. 2.Be set to 5S and 25S the cycling time of the time relay 2, the attaching plug of the power-line plug of air switch 2 and D.C. regulated power supply 3 insert the test site～the 220V socket in, press the switch connection power supply of air switch 2 and D.C. regulated power supply 3 then, the endurancing of car cleaning device has just begun.
Its principle of work is:
1, the control of scrubber water spray
As the air switch 2 closed solenoid energising 5S that connect the closed 5S → A.C. contactor 4 of solenoid energising 5S → time relay 1 normally closed contact that makes the time relay 1.The normally opened contact K1 closure of A.C. contactor 4 makes scrubber motor 6 energising 5S → scrubber water spray 5S.
2, the scrubber control that stops to spray water
The time relay 1 energising 5S is recycled to normally opened contact K1 that normally closed contact that 25S makes the time relay 1 second disconnects the solenoid outage 25S → A.C. contactor 4 of 25S → A.C. contactor 4 and disconnects and make scrubber motor 6 outage 25S → scrubbers stop the 25S that sprays water after second.
Test constantly circulates for the one action cyclic process by above-mentioned 1 and 2, up to off-test.
