[0022] The technology first adds a layer of transparent adhesive material (PVB) between the left outer ordinary glass 1 and the inner polycarbonate glass 4 through a laminating process, and then uses a sealing sleeve to cover the four sides of the left outer ordinary glass 1 and the inner polycarbonate glass 4, and then extracts the air in the left outer ordinary glass 1 and the inner polycarbonate glass 4 through a sealing sleeve to make the left outer ordinary glass 1 and the inner polycarbonate glass 4 initially bonded, and then puts the initially bonded left outer ordinary glass 1 and the inner polycarbonate glass 4 in an autoclave, and the temperature in the autoclave is set to room temperature 25°C, and the left outer ordinary glass 1 and the inner polycarbonate glass 4 are bonded by vacuum pressure. The residual air in the inner polycarbonate glass 4 is extracted, and finally the metal film 5 is attached, and the left frameless window laminated glass is formed by 45° overlapping extrusion, and the process of making the right frameless window laminated glass through the right outer ordinary glass 2 and the inner polycarbonate glass 4 is the same as above. This structure adopts the left outer ordinary glass 1 or the right outer ordinary glass 2 + PVB film 3 + inner polycarbonate glass 4 + metal film 5 mixed mode, and the left and right frameless window laminated glass assembly is reduced by about 20%. This structure is suitable for connecting ordinary glass of different thicknesses with polycarbonate glass of different thicknesses, has strong versatility, and reduces development and component costs.

[0023] In this embodiment, the left outer ordinary glass 1 and the right outer ordinary glass 2 are respectively connected with the two PVB films 3, the two inner polycarbonate glasses 4 and the two metal films 5 by means of laminating process, air extraction by sealing sleeve, air extraction at room temperature and high pressure in an autoclave, mounting overlapping extrusion and the like;
