Description

Automobile sun-shading curtain

Technical Field

The utility model relates to a technical field of car sunshade screen, in particular to car sunshade screen.

Background

The automobile sun-shading curtain is a strong device used for blocking the automobile from entering the automobile.

The existing automobile sunshade curtain used on the automobile door on one side of an automobile cab comprises a frame and sunshade cloth, wherein a plurality of light transmission holes are formed in the sunshade cloth, a driver can see the sunshade curtain through the light transmission holes, and the limitation of the sunshade cloth on the visual field of the driver in the process of blocking strong light is reduced.

The defects in the prior art are as follows: light gets into the driver's cabin through the light trap, though the sunshade screen has blockked partial highlight, but when the light that the light trap passes through entered into the driver's cabin, the facula that sees through the light trap is still very strong to the irradiation intensity of driver's cabin, and the driver sees through the light trap and watches the outside sight that can influence the driver equally of driver, and the driver will have the light trap on seeing the sunshade screen when watching the external conditions, forms more obvious spot, influences the vision.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to: the automobile sun-shading curtain has the advantages of better blocking strong light and reducing the influence on the vision of a driver.

The technical scheme includes that the automobile sunshade curtain comprises sunshade cloth and a support frame located on the periphery of the sunshade cloth, light holes are formed in the sunshade cloth at intervals, diffraction holes are formed in the sunshade cloth and the light holes at intervals, and the diameters of the light holes are larger than the diameters of the diffraction holes.

Through the technical scheme, the support frame plays the supporting role for the puggaree, the handheld support frame of face installs it on the door window in the use, simple to operate, reduce because the inconvenient condition on soft puggaree subsides the door window, let light form the diffraction of light behind the diffraction hole through the diffraction hole, light can be on a wider scale get into the driver's cabin, light after the puggaree can block partial highlight simultaneously, light through the diffraction hole can be dispersed to more area by the diffraction phenomenon simultaneously, and then the intensity of receiving light on every point has been reduced, the light trap is the effect that the driver sees the outside condition through the light trap, after seting up of diffraction hole, can reduce the required light trap, and then can reduce the aperture of light trap.

Furthermore, the support frame is provided with a fixing piece used for fixing the automobile glass.

Through above-mentioned technical scheme, fix the support frame on the door window through the mounting, it is more convenient to operate, because the puggaree is soft forage, so fixed with the door window through the mounting on the support frame, relative and fixed with the door window through sunshade net, more firm.

Further, the fixing part comprises a magnet fixed on the periphery of the support frame.

Through above-mentioned technical scheme, through the absorption of magnet, for other fixed mode, it is more convenient to connect, only need with it and door window to it can adsorb through magnet.

Furthermore, the support frame is provided with a concave part for embedding the fixing piece.

Through above-mentioned technical scheme, through setting up the mounting in the depressed part, when can letting support frame and door window be connected, the edge at the door window can be pasted in the support frame outside, has reduced the gap that appears between sunshade screen and the door window, has reduced the light irradiation between door window and the sunshade screen gap.

Furthermore, the sunken part is located the support frame and keeps away from puggaree one side.

Through above-mentioned technical scheme, through keeping away from puggaree one side with the depressed part setting at the support frame, let the bulge at depressed part back be located inside the support frame, reduced the space that the bulge took, can not be owing to the surface unevenness with the bulge production in the support frame side.

Furthermore, the diameter of each light hole is 0.9-2.2mm, and the distance between every two adjacent light holes is 1.9-2.1 mm.

Through the technical scheme, in a cab, the distance between door glass and a driver is about 30mm, the setting of the light-transmitting aperture is that in the distance, the aperture smaller than 0.9mm can generate obvious diffraction phenomenon, when the aperture exceeds 2.2mm, the center of the aperture can disappear diffraction effect, strong light spots can appear, and shading effect is reduced, because the light-transmitting apertures mainly play a role of light supplement, the too strong diffraction intensity can cause the influence of excessively weakening the light supplement effect, the light-transmitting apertures are set in the aperture larger than 0.9mm, the diffraction phenomenon is less, the distance between two light-transmitting apertures is set to be 2mm, at the moment, the light just passing through the light-transmitting apertures can cover the middle point position of two adjacent light-transmitting apertures, because the body part of the driver is different from the distance of a lathe, the height, the weight and the size of the driver are different, and further different drivers are matched to set error distances, therefore, the distance of the light holes is 1.9-2.1mm, and spots formed after the sun-shading cloth is penetrated are reduced.

Further, the diameter of each diffraction hole is 0.1-0.5mm, and the distance between every two adjacent diffraction holes is 0.1-0.5 mm.

Through the technical scheme, when the diameter of the diffraction hole is 01.mm and the distance between the two diffraction holes is 0.1-0.5mm, light spots generated by diffraction between the two gaps can be more covered between the sunshade cloth between the two diffraction holes, the back of the sunshade cloth can be more easily observed through the sunshade cloth, the blocking of the sunshade cloth to the visual field is reduced, and meanwhile, the irradiation of strong light can be weakened.

Through above-mentioned technical scheme, the aperture of diffraction hole can let the light take place the diffraction after the diffraction hole, because the distance between two adjacent diffraction holes is less, can cover the position that can not cover between the adjacent diffraction hole after the diffraction of diffraction hole, has reduced the influence of puggaree to the sight.

Furthermore, the periphery of the sunshade cloth is integrally connected with a coating ring coated on the periphery of the support frame.

Through above-mentioned technical scheme, with the support frame cladding in the cladding circle, fixed effect is better, can not drop because sticky back glue, other connected mode relatively, the cladding is more stable in the connection of cladding circle, is difficult for droing.

Furthermore, the coating ring is made of cloth, anti-skid grains are arranged on the coating ring, and the angle between the grains of the anti-skid grains and the edge where the corresponding grains of the sun-shading cloth are located is 21-71 degrees.

Through above-mentioned technical scheme, because the sideline and the line at the cladding circle are close the condition of not aesthetic appearance when perpendicular, in order to make the line perpendicular with the cladding circle, the required precision is higher, sets up city inclination with the line of antiskid line and the sideline of puggaree and has reduced the precision to perpendicular requirement, and the course of working is more convenient.

To sum up the utility model discloses following technological effect has:

1. support and the absorption of magnet through the support frame and make the installation more convenient.

2. Through the arrangement of the light holes and the diffraction holes, light can uniformly enter the cab through light diffraction, and strong light irradiation is weakened;

3. the light intensity can be weakened while the transmittance is more reasonably controlled through the light-transmitting aperture, the distance between two adjacent light-transmitting holes, the diffraction holes and the distance between two adjacent diffraction holes;

4. the viewing sensory effect of people is better when the angle between the anti-skid lines and the edges of the sun-shading cloth is vertical.
