Description

Photochromic film sticking structure for automobile and photochromic film Technical Field The application relates to the technical field of automobile parts, in particular to a photochromic film sticking structure for an automobile and a photochromic film. Background The photochromic film is widely used as a body film of an automobile, and changes in color when ultraviolet rays or sunlight are absorbed by the photochromic film, and the photochromic film returns to the original color according to indoor and outdoor temperatures when the ultraviolet rays or sunlight are lost. At present, in order to meet the demands of users, the photochromic film is manufactured into a preset shape required by the users, and is spliced with a common non-color-changing car film and then is adhered to the car body of the car, so that when the car body does not receive illumination, the color of the photochromic film is consistent with that of the common car film, and after the car body receives illumination, only the color of the photochromic film with the preset shape changes, so that the personalized car film is formed. When the photochromic film is spliced with the common car film, a notch area with the preset shape consistent with the photochromic film is cut out in advance on the common car film, and then the photochromic film is adhered to the notch area, but the adhered part of the photochromic film and the common car film is easy to tilt due to water seepage, so that the photochromic film is easy to adhere unstably and is fixedly dropped in a short time. Disclosure of Invention In order to make the adhesion of the photochromic film more firm, the application provides an adhesion structure of the photochromic film for an automobile and the photochromic film. The first object of the present application is achieved by the following technical solutions: the utility model provides a structure is pasted to photochromic membrane for car, includes ordinary car rete, photochromic rete and transparent rete, ordinary car rete paste the face and be used for pasting fixedly with the automobile body, ordinary car rete is sunken to have the pasting groove in the one side of face that pastes the face dorsad, the profile in pasting the groove is unanimous with the photochromic membrane, the photochromic rete is fixed in and pastes the inslot, transparent rete pastes fixedly and with ordinary car rete is pasted the face of face dorsad transparent rete covers the photochromic rete. According to the technical scheme, after the patterns of the photochromic films which are required to be manufactured by a user are obtained or the photochromic films with fixed shapes are produced in batches, the common car film is punched to form the pasting groove which is consistent with the shape of the photochromic films, then the photochromic film is pasted in the pasting groove, so that the photochromic film can not protrude from the surface of a car body, and finally the common car film and the photochromic film are covered and fixed by the transparent film. Furthermore, even if water permeates the transparent film layer and permeates the adhesive groove, only part of the photochromic film layer is permeated and replaced, and the common car film layer is still intact. Optionally, when the photochromic film layer is fixed in the adhesion groove, one end of the photochromic film layer away from the bottom of the adhesion groove is flush with the notch of the adhesion groove. Through adopting above-mentioned technical scheme, the one side that paste the groove is kept away from to the photochromic rete sets up with pasting the notch parallel and level in groove for the photochromic rete is complete to be filled to paste the groove, improves the roughness of the surface after the automobile body completion pad pasting. Optionally, a sealant is coated and filled between the edge of the photochromic film layer and the side wall of the adhesive groove. Through adopting above-mentioned technical scheme, before transparent rete is pasted and is fixed on ordinary car rete surface, the coating sealant makes the gap between photochromic rete and the lateral wall of pasting the groove cover, simultaneously, if the water is gone into transparent rete and is reached when pasting the groove, because the barrier of sealant, the water also is difficult for from the edge infiltration of photochromic rete, and the bonding of photochromic rete is also more firm. Optionally, the device further comprises a detachable limiting block, wherein the limiting block is in a strip shape and flexible, the limiting block is fixed with the edge of the photochromic film layer and the common car film layer, and the limiting block covers the sealant. Through adopting above-mentioned technical scheme, after accomplishing the coating of sealant, in order to restrict unnecessary sealant that overflows to overflow to flow to photochromic rete or ordinary car rete to unable complete laminatin
