Description
Technical Field
The utility model relates to an use functional film on car front windshield surface, concretely relates to have middle high light transmittance, the PET gradual change membrane of both sides low light transmittance belongs to auto-parts technical field.
Background
Currently, a tinted window film is typically applied to the surface of the window glass of a vehicle for aesthetic or privacy reasons. However, for the driving of the car owner, the sight line is easily blocked by the dyed window film, and great potential safety hazards exist.
In the prior art, the light transmittance of the front automobile bumper is the same, and the high-light-transmittance front automobile bumper film generally does not influence the sight, but has insufficient sun-shading effect; the automobile film with low light transmittance can not be used for the front windshield of the automobile glass, and the visual field is easy to deteriorate, so that certain physical contradiction exists, and the practicability is not high.
In view of the above-mentioned prior art, the applicant of the present invention has made a lot of repeated and beneficial researches, and the final product has obtained effective results and formed the technical solutions to be described below.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides a PET gradual change membrane to the car window membrane of solving among the prior art can not satisfy simultaneously neither influence the sight can play the problem of sunshade protective effect again.
In order to achieve the above object, the present invention provides the following technical solutions:
a PET gradual change film comprises a low light transmission part and a high light transmission part which are integrally connected;
the low light transmission part is arranged on at least one side part of the PET gradual change film;
the high light transmission part is arranged on the part of the PET gradual change film without the low light transmission part.
On the basis of the technical scheme, the utility model discloses can also do as follows the improvement:
furthermore, the low light transmission parts are respectively positioned at two side parts of the PET gradual change film, and the high light transmission parts are positioned in the middle part of the PET gradual change film.
Furthermore, the low light-transmitting part is positioned at one side part of the PET gradient film;
the high light transmission part is positioned in the middle of the PET gradual change film and on the other side part far away from the low light transmission part.
Further, the light transmittance of the high light transmittance part is not less than 70%.
Further, the light transmittance of the low light-transmitting portion is not higher than 35%.
Further, the width range of the high light transmission part is 40-60 cm.
Further, the width range of the low light transmission part is 10-20 cm.
Further, the overall thickness range of the PET gradient film is 23-188 micrometers.
The utility model has the advantages of as follows:
the device can effectively reduce direct sunlight through setting up on the fender window before the car to guarantee the place ahead field of vision when driving, compromise field of vision nature and sunshade effect simultaneously, improved functional practicality greatly.
Drawings
In order to clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below, and the structures, proportions, sizes, etc. shown in the present specification are only used to match the contents disclosed in the specification, so as to be understood and read by those skilled in the art, and any modifications of the structures, changes of the proportion relations, or adjustments of the sizes, should still fall within the scope of the technical contents disclosed in the present invention without affecting the functions and the achievable objects of the present invention.
Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.
In the drawings, the components represented by the respective reference numerals are listed below:
a high light transmission part 1 and a low light transmission part 2.
Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
As shown in fig. 1, the embodiment of the utility model provides a PET gradual change membrane, high printing opacity portion 1 and low printing opacity portion 2 including a body coupling, wherein high printing opacity portion 1 is located in the middle of, low printing opacity portion 2 is located respectively high printing opacity portion 1's both sides for setting up the luminousness about playing on the fender window before the car is low, the effect that middle luminousness is high can effectively reduce the sunshine of top side and penetrate directly and the bonnet reflection of light of bottom side, can borrow the place ahead field of vision when the assurance driving of a car by middle high printing opacity portion 1 simultaneously.
Specifically, the light transmittance of the high light transmission part 1 is not lower than 70%, the light transmittance of the low light transmission part 2 is not higher than 35%, the width range of the high light transmission part 1 is 40-60 cm, and the width range of the low light transmission part 2 is 10-20 cm, so that the field of view and the sun-shading effect are considered, and the functional practicability is improved.
The PET gradient film is produced by a PET extrusion method, three layers of base materials from an extrusion die head are formed by co-extrusion, and the whole thickness range is 23-188 micrometers.
Example 2
In embodiment 2, the same reference numerals are given to the same structures as those in embodiment 1, and the same description is omitted, and embodiment 2 is improved over embodiment 1, in which the low light transmission part 2 is integrally connected to the high light transmission part 1, the low light transmission part 2 is located at the whole upper part, and the high light transmission part 1 is located at the whole lower part, so as to function as low upper light transmittance and high middle and lower light transmittance, increase the light transmission area, and effectively ensure the visual field effect during driving.
The PET gradient film is used in the following process:
when the PET gradual change film is used, the whole PET gradual change film is attached to the front windshield of the automobile glass, the low light transmission part 2 is positioned at the upper part, and the high light transmission part 1 is positioned at the middle or middle lower part.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
