Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, also can obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is circulation type automobile wiper RTA reliability test assembly structural representation of the present invention;
Fig. 2 is circulation type automobile wiper method for testing reliability process flow diagram of the present invention;
In figure, sequence number is described as follows: 1 fail-test case, 2 circulation shower nozzles, 3 water smokes, 4 simulation front window unit, 5 infrared ray registering instruments, 6 stabilized voltage supplys, hydraulic pressure sensor, 8 intelligent circulation water pumps, 9 moisturizing passages.
Embodiment
Enable above-mentioned purpose of the present invention, feature and advantage become apparent more, below in conjunction with accompanying drawing 1 and Fig. 2 and embodiment, the present invention is further detailed explanation.
In the present embodiment, the circulation type automobile wiper RTA reliability test assembly adopted, comprise stabilized voltage supply 6, fail-test case 1 with moisturizing passage 9, this fail-test case 1 is upper shed structure, water is equipped with in inside, is provided with hydraulic pressure sensor 7 in water, and the sidewall of fail-test case 1 is also provided with circulation shower nozzle 2, just arrange simulation front window unit 4 to the front of circulation shower nozzle 2, circulation shower nozzle 2 water spray 3 is on simulation front window unit 4.Before simulation front window unit 4, be also provided with infrared ray registering instrument 5, infrared ray is incident upon on simulation front window unit 4, and in fail-test case 1, be also provided with intelligent circulation water pump 8, intelligent circulation water pump 8 connects circulation shower nozzle 2.Infrared ray registering instrument 5 can be arranged on the support just to simulation front window unit 4.Stabilized voltage supply 6 is simultaneously for infrared ray registering instrument 5, hydraulic pressure sensor 7, intelligent circulation water pump 8 are powered.
The circulation type automobile wiper method for testing reliability adopted in the present embodiment, comprises the following steps:
Step 101, controlled circulation shower nozzle launches water smoke to simulation front window unit.Water in circulation shower nozzle is provided by intelligent circulation water pump.First in fail-test box unit, inject water, utilize the degree of depth of hydraulic pressure sensor unit determination water, hydraulic pressure P=ρ * g*h, ρ is the density of water, and g is that constant gets 9.8N/kg, and h is the depth of water.Determine two standard values to hydraulic pressure sensor unit, one is the highest depth of water, and the present embodiment is set as 4900Pa, and show that water surface elevation is 0.5m, another is water surface minimum altitude, and the present embodiment is set as 1960Pa, show that water surface elevation is 0.2m.
As the 4900Pa that hydraulic pressure sets higher than hydraulic pressure sensor unit, a trigger pip can be sent, now start intelligent circulation water pump to start to draw water, recirculated water in chamber to be provided for circulation shower nozzle by intelligent circulation water pump, send the water smoke needed for simulation front window unit by circulation shower nozzle again, and flow to intelligent circulation water pump by passage; As the 1960Pa that hydraulic pressure sets lower than hydraulic pressure sensor unit 7, hydraulic pressure sensor unit can send the sound of blowing a whistle dripped, and reminds laboratory technician to carry out moisturizing.
Step 102, starts wiper along the to-and-fro movement of simulation front window unit.In the present embodiment, utilize the number of times that infrared ray registering instrument swings to record wiper, wiper is come and gone and within one week, is recorded as 1 time.
Step 103, monitoring Wiper blade times of exercise, if reach foot 500,000 times, and the continuous or interrupted waterline of many different in width is there is on simulation front window unit, and 75% wiped clean of at least whole window ara (can artificially assert), then tested Wiper blade is qualified, otherwise, Wiper blade should be changed and proceed test; Monitoring Wiper arm, motor and windscreen wiper kinematic link times of exercise, if reach 1,500,000 times, and bearing and hinged place are flexibly connected intact, then tested Wiper arm, motor and windscreen wiper kinematic link are qualified, otherwise, damage parts should be changed, proceed test; Only when all parts are all qualified, assert that wiper is qualified.
As Wiper blade midway is damaged, need the Wiper blade again more renewed, but infrared ray registering instrument 5 does not reset in this process, proceed test to other for damaging parts, Wiper blade then re-starts 500,000 fail-tests again.If the damage of Wiper arm, motor and connecting rod is also in like manner, only need the exemplar more renewed, infrared ray registering instrument does not reset, and needs to re-start 1,500,000 times ten thousand times fail-tests.When whole part all completes fail-test, and all qualified, can determine that this wiper system is qualified.
Although the foregoing describe the specific embodiment of the present invention, the those skilled in the art in this area should be appreciated that these only illustrate, can make various changes or modifications, and do not deviate from principle of the present invention and essence to these embodiments.Scope of the present invention is only defined by the appended claims.
