Description
Technical field
The present invention relates to a kind of checking device and its operating method for car light design anti-fog performance, belong to motor vehicle
Technical field of lamps.
Background technology
Automobile lamp mostly uses bulb as light source at present, and lamp housing, lampshade and speculum etc. are by plastic material
Make, therefore have the characteristics that cost is low, weight is light.But automobile lamp is at work, can be produced after light source is lit a large amount of
Heat, if heat can not be handled timely and effectively, the service life and performance of surrounding components can be influenceed.Inside and outside light fixture
When the temperature difference is larger, lamp interior is uneven in temperature in addition, and fog can be produced in the periphery of lampshade especially bottom, and car light hazes not
The outward appearance of light fixture is only influenceed, and can decline the lighting quality of light fixture, the traveling to vehicle brings potential safety hazard.
The content of the invention
It is an object of the invention to provide a kind of checking device of car light design anti-fog performance and its operating method, Neng Gou
The reserved spacing of lampshade and decorative circle in board design scheme in car light design process, and verify that it influences on car light anti-fog performance,
So as to which the problem of hazing of light fixture is prevented and controlled in the car light design phase.
The present invention is that the technical scheme for reaching above-mentioned purpose is：A kind of checking device of car light design anti-fog performance, its
It is characterised by：Cell body including bulb, lifter plate, two sideskids and humidity sensor and for containing liquid, two sides
Slide plate sealing is inserted on the cell wall of cell body and can moved in the horizontal direction, and cell body is separated into the height of lower section by two sideskids
Wet sump and the low humidity groove of top, there is the ventilative spacing for controlling that moisture spreads into low humidity groove in high wet sump between two sideskids
△ h, described ventilative spacing △ h are equal to the spacing △ H between lampshade side and decorative circle；The bulb and for detecting high wet sump
The humidity sensor of interior humidity is arranged on high wet sump and breakked away positioned at the top of liquid level, the inductive head of humidity sensor positioned at two
The underface of plate closing position；The lifter plate that can be moved up and down, and lifter plate and two sideskids are installed in the low humidity groove
Between there is the separation delta X that height separation delta x, described height separation delta x are equal between lampshade front and decorative circle, installed in low
Flexible sealing gasket in wet sump seals to the inwall of two sideskids and lifter plate and low humidity groove, and sealing gasket is used for
Support lifter plate.
The lifter plate top has connecting rod, the height separation delta x between lifter plate and two sideskids 2.5mm~
Between 50mm, cell body is provided with the scale measured to lifter plate.
Ventilative spacing △ h between described two sideskids are equipped with to enter it in 1mm~50mm on two sideskids
The scale of row metering, the both sides of each sideskid are provided with positive stop lug boss.
Described sealing gasket is foaming EPDM materials.
One of which of the power of the bulb in 5W, 16W, 21W, 35W or 55W.
The operating method of the checking device of the car light design anti-fog performance of the present invention, it is characterised in that：According to following step
It is rapid to carry out：
(1), liquid will be added in cell body, and by Liquid level in the lower section of bulb；
(2), the ventilative spacing △ h closed between two sideskids, moisture diffusion in high wet sump is avoided in low humidity groove,
Lifter plate is taken out, low humidity groove is communicated 1 ± 0.1h with external environment, the temperature of described external environment is wet at 20 DEG C~25 DEG C
Degree is in 45%RH~55%RH；
(3), lifter plate is loaded in low humidity groove, demarcates the height separation delta x of required detection between lifter plate and sideskid,
And two sideskids are moved, demarcate the ventilative spacing △ h of required detection between two sideskids；
(4), bulb lighted under 13.5V voltages, and bulb keeps Chang Liang, observes in low humidity groove whether fog occur, when going out
Test can terminate during existing fog；Test can terminate when not occurring fog to 720min between when tested, and record test starts
It is wet when state detects test beginning state to the time and humidity sensor for testing done state and tests done state
Angle value；
(5), adjust again between lifter plate and sideskid between the height separation delta x and two sideskids of required detection
During ventilative spacing △ h, second step is repeated to four steps, is terminated to checking.
The checking device of anti-fog performance of the present invention uses cell body, the bulb on cell body, lifter plate and two sides
Slide plate and humidity sensor, cell body is separated into the high wet sump of lower section and the low humidity groove of top by two sideskids, passes through two
The ventilative spacing △ h of the relative movement of individual sideskid simulate the spacing △ H between the lampshade side of car light and decorative circle, and lift
Height separation delta x simulates car light lampshade front and the separation delta X of decorative circle between plate and two sideskids, by being arranged on high wet sump
Interior liquid can change between ventilative between two sideskids on the cell body as the moisture source spread to low humidity groove
The working condition come away from height separation delta x between △ h, and lifter plate and two sideskids inside equivalent car light, passes through observation
The situation that hazes when different ventilative spacing △ h and different height separation delta x change, in board design scheme lampshade with
The reserved spacing of decorative circle influences on car light anti-fog performance, so as to obtain lampshade and the reference value of decorative circle spacing when car light designs, is
The antifog design of car light provides reference, reduces light fixture exploitation and the risk to be hazed during the production phase.The checking device of the present invention
Simple in construction, manufacturing cost is low, easy to operate, due to that by testing the size of the spacing can be verified to mist in the car light design phase
The influence that gas is formed, hazed risk so as to effectively reduce vehicle lamp assembly, improve the performance of light fixture, the problem that hazed to car light rises
To prevention and the effect of control.
