Abstract
The utility model discloses an automatic test device of automobile window wipers, comprising one or more test storehouses and a test head; a water storage tank is installed on the base board in the test storehouse; the water storage tank is internally and respectively provided with a submersible pump and a water level sensor; the water storage tank is internally provided with an automatic water inlet, a water exchanging opening and a filtered water inlet; the top board in the test storehouse is respectively provided with a gimbaled nozzle with water-proof lighting function rightly opposite to the test head; the test head is arranged on a test trailer; and the window wipers on the windscreen of the test head are respectively connected with a motor of the window wipers and a corner detecting sensor in transmission manner. The circuits of the test device are all controlled by a PLC connected with a control cabinet. The automatic test device has reasonable design structure without artificial interventions so that the test results are prone to practical use conditions so as to be capable of reflecting product quality efficiently.
Description
Technical field
The utility model relates to auto manufacturing, mainly is a kind of automobile wiper device automatic test equipment.
Background technology
The automobile wiper device is the vitals that guarantees the good sight line of driver when exercising the automobile rainy day, generally be installed in the front windshield outside of automobile, the dependability of automobile wiper device and effect not only are related to the quality that automobile is exercised sight line, also directly influence the enforcement safety of automobile; Reliability and effect in order to guarantee that the automobile wiper device uses are very important to its long duration test of carrying out under the analog operation state.
At present, existing test normally: in an airtight space, simulation rain spray system is installed, the windshield wiper of testing is installed on the windshield of specifying vehicle by support tests.Whether the variation of the switching of windshield wiper velocity mode, rain spray amount, windshield wiper quit work etc. all needs manually-operated and observation, manual intervention experimental result like this may be very big, and test findings and actual user mode are distinguishing, can not effectively reflect the quality of product.
The utility model content
Technical problem to be solved in the utility model provides a kind of automobile wiper device automatic test equipment, does not need to use manual control, and the possibility of human intervention is little like this, and test findings trends towards actual operating position, can the effecting reaction product quality.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automobile wiper device automatic test equipment, include test cabin, the test headstock, described test cabin is by aluminum alloy frame and is installed on the glass room that glass plate constituted in the aluminum alloy frame, it is characterized in that: described test cabin has and one or morely interconnects and become a row, has the base plate of band grid in the test cabin, and floor below has aqua storage tank, be separately installed with submersible pump and level sensor in the aqua storage tank, the aqua storage tank sidewall is provided with automatic water inlet, changes the mouth of a river, the filtered water inlet; The waterproof illuminating lamp is installed respectively and is faced the universal sprinkler head of testing headstock on the inside ceiling panel of experiment storehouse; Described test headstock is placed on the experiment carriage; On the described test cabin sidewall pole is installed, the pole front end is equipped with windshield wiper, also comprises being installed on instruction carriage first speed wind rotation angle detecting sensor on glass.
The circuit of test unit is by the PLC control that is connected on the switch board.
Test principle of the present utility model is test and the detection that utilizes the circulated sprinkling system simulation state that rains naturally that windshield wiper is carried out under multiple mode of operation.The installation site that has kept windshield and windshield wiper in the utility model is installed in windshield wiper on the headstock original position and tests, and such test figure is true and reliable.Design simultaneously has a plurality of test cabins, both can use separately, also can test a plurality of windshield wipers with kind or different cultivars simultaneously.Warehouse adopts the standard streamline aluminium profile as framework, and the side is transparent toughened glass.
Adopt the PLC control submersible pump that combines with frequency converter in the utility model, reach the effect of automatic selection, the different rainfall of switching.Adopt PLC and current detecting unit to monitor the working condition of windshield wiper motor all the time, when the motor generation stuck or when burning system stop test and warning, writing time automatically.Adopt rotation angle detecting sensor, monitor the windshield wiper wiper situation that puts in place all the time, when motor stall or motor are normal but scrape the work of brush arm damage parts when undesired, system will stop test and warning, writing time automatically.Long when test period, when recirculated water was lost to setting value, level sensor notified PLC that automatic water inlet is opened automatically, and when water was filled it up with, water inlet was closed automatically.Common windshield wiper has three kinds of working methods: at a high speed, the work of low speed, gap, by PLC control, any working method can be switched at arbitrary period in system.
The utility model has the advantages that:
The utility model project organization is reasonable, does not have artificial intervention, makes test findings trend towards actual operating position, can the effecting reaction product quality.
