Description

Technical Field

[0001] The utility model relates to a protective film, more specifically, to a double-screen protective film for a vehicle-mounted touch screen. Background Art

[0002] As high-end car touch screens are getting bigger and bigger, it has become a popular structure to integrate the central control and the instrument. Since the central control needs to be assembled with a touch screen, but the instrument does not need a touch screen, there will be a height difference between the left and right parts of the dual screen. When TP manufacturers ship dual-screen products to customers, the protective film on the back is usually applied twice, which is completed in two processes. This two-step film application is relatively inefficient.

[0003] Chinese invention patent document CN100476454C discloses an optical film, which is integrally formed, characterized in that the optical film includes: a first film sheet, which is in the shape of a long rectangle and has a first protrusion; a second film sheet, which is in the shape of a long rectangle and has a second protrusion; and a connecting member for connecting the first film sheet and the second film sheet; wherein, when the first film sheet and the second film sheet are rotated and stacked around the connecting member in a plane, the long and short sides of the first film sheet and the second film sheet are aligned, and the first protrusion is aligned with the second protrusion. The first film sheet has a first structural surface and a first relative surface, and the first structural surface has a plurality of first optical structures, and the second film sheet has a second structural surface and a second relative surface, and the second structural surface has a plurality of second optical structures. The first optical structures and the second optical structures are prisms. The prisms are linear prisms, and the prism lines of the linear prisms extend straight and are arranged parallel to each other. The prisms are linear prisms, and the prism lines of the linear prisms extend in a wavy shape and are arranged adjacent to each other. The invention also discloses an optical film for assembly in a frame, characterized in that the optical film includes a first film sheet, a second film sheet and a connecting member connected into one body: the first film sheet is in the shape of a long rectangle and has a first structural surface and a first relative surface; the second film sheet is also in the shape of a long rectangle and is located below the first film sheet, and the second film sheet has a second structural surface and a second relative surface; the connecting member has a first end and a second end, the first end is connected to the first film sheet, and the second end is connected to the second film sheet, when the first film sheet and the second film sheet rotate around the connecting member in a plane, the long and short sides of the first film sheet and the second film sheet are aligned, and the second structural surface of the second film sheet is adjacent to the first relative surface of the first film sheet, and the connecting member forms a positioning protrusion that protrudes outward and can be assembled in the frame for positioning. The first structural surface of the first diaphragm has a plurality of first prisms, and the second structural surface of the second diaphragm has a plurality of second prisms. The first prisms are linear prisms, and the second prisms are linear prisms. The prism lines of the first prisms and the prism lines of the second prisms extend straight and intersect with each other to form an angle. The angle is greater than 0 degrees and less than or equal to 90 degrees. The first prisms are linear prisms, and the second prisms are linear prisms. The prism lines of the first prisms extend in a wavy shape along a first axial direction, and the prism lines of the second prisms extend in a wavy shape along a second axial direction. The first axial direction and the second axial direction intersect to form an angle. The angle is greater than 0 degrees and less than or equal to 90 degrees. At least one of the first diaphragm and the second diaphragm has a protrusion for assembly and positioning.

[0004] Obviously, the patent connects two films that can condense light and increase brightness to avoid identification errors by operators during assembly, thereby shortening the working hours and improving assembly efficiency. This structure cannot solve the cumbersome operation problem of the existing two-time film application.

An adsorption platform is arranged above the film pasting platform, and a plurality of adsorption air channels connected to the air pump inside the chassis are arranged at the upper end of the film pasting platform and the lower end of the adsorption platform. The air pump draws air outward through the adsorption air channels, and forms negative pressure between the backlight module and the film pasting platform, and between the film material and the adsorption platform, so as to fix the backlight source and remove the film material. A bracket is fixedly installed at the rear end of the storage box, and a No. 1 transverse guide rail is installed on the upper end of the bracket. The adsorption platform is arranged below the No. 1 transverse guide rail, and a No. 1 transverse linear motor is installed on the upper end of the No. 1 transverse guide rail. The axial linear motion of the No. 1 transverse linear motor is an existing and mature motor technology, which is developed from a traditional rotating motor. The No. 1 transverse guide rail has a magnetic track, and the No. 1 transverse linear motor moves on the magnetic track through electromagnetic force, so that the adsorption platform moves back and forth between the film pasting platform and the top of the storage box. A vertical oil cylinder is provided at the lower end of the No. 1 transverse guide rail, and a connecting frame is fixedly connected between the vertical oil cylinder and the No. 1 transverse linear motor. The adsorption platform is fixedly installed at the lower end of the hydraulic actuator of the vertical oil cylinder.
