Description

Technical Field

[0001] This utility model relates to the field of dimming glass technology, and in particular to a dimming glass system for passenger car side windows. Background Technology

[0002] Smart glass is a light-controlling device, primarily consisting of a dimming film sandwiched between two layers of transparent glass. Types of dimming films include suspended particle dimming films (SPD), polymer-dispersed liquid crystal (PDLC) dimming films, electrochromic (EC) dimming films, thermochromic dimming films, and photochromic dimming films. For suspended particle dimming films, polymer-dispersed liquid crystal dimming films, and electrochromic dimming films, when electricity is applied, the arrangement or state of the materials in the dimming film changes, thereby altering the light transmission characteristics of the smart glass, such as switching from low to high transmittance, or vice versa. This type of smart glass, which achieves rapid switching between on and off states through the action of an electric field / current, offers advantages in actively controlling light transmittance and energy saving. This device can be used as smart windows, rearview mirrors, sunglasses, displays, etc., in spacecraft, high-speed trains, automobiles, and buildings.

[0003] Although smart glass has been successfully developed for many years, it has not yet been practically applied to passenger car side windows. In particular, the application of suspended particle smart glass and polymer-dispersed liquid crystal smart glass in passenger car side windows still raises concerns about electrical safety. The main reason is that suspended particle smart glass and polymer-dispersed liquid crystal smart glass require high driving voltages, generally exceeding 48V AC, and even reaching hundreds of volts; while passenger cars typically provide 12V DC power. Therefore, a controller is needed to convert the 12V DC power into tens or even hundreds of volts of AC power. Furthermore, side window glass is a moving component and must be able to open normally.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] like Figure 1As shown, this utility model provides a passenger car side window dimming glass system, including side window dimming glass 1, controller 2 and high voltage wiring harness. The side window dimming glass 1 includes a dimming area 11 and a non-dimming area 12. The controller 2 is fixed in the non-dimming area 12. The dimming area 11 and the controller 2 are electrically connected through the high voltage wiring harness.

[0022] In the above scheme, the controller 2 is internally equipped with an inverter, a transformer and a circuit controller.

[0023] The dimming area 11 is consistent with the shape of the passenger car side window.

[0024] The non-dimming area 12 is hidden inside the side door of the passenger vehicle.

[0025] Specifically, the controller 2 is electrically connected to the passenger vehicle power system.

[0026] Preferably, the controller 2 is electrically connected to the central control system of the passenger vehicle.

[0027] Based on this, the passenger vehicle central control system regulates the controller 2 to input a given voltage or current value to the dimming area 11 according to a preset program.

[0028] Furthermore, such as Figure 2 As shown, the dimming area 11 includes a first transparent substrate 1-1, a second transparent substrate 1-5, and a dimming film 1-3 disposed between the first transparent substrate 1-1 and the second transparent substrate 1-5; a first interlayer 1-2 is disposed between the first transparent substrate 1-1 and the dimming film 1-3, and a second interlayer 1-4 is disposed between the second transparent substrate 1-5 and the dimming film 1-3.

[0029] The dimming films 1-3 are one of the following: electrochromic dimming film, suspended particle dimming film, polymer dispersed liquid crystal dimming film, and dye liquid crystal dimming film.

[0030] The first transparent substrate 1-1 and the second transparent substrate 1-5 are transparent glass, which can be inorganic glass, organic glass, or functional glass, such as UV blocking glass, IR blocking glass, Low-E glass, tempered glass or antibacterial glass, etc. They can also be selected from colored glass such as gray glass and brown glass.

[0031] The first interlayer 1-2 and the second interlayer 1-4 are EVA film, TPU film, PVB film, or functional film, such as UV-blocking EVA film, UV-blocking TPU film, UV-blocking PVB film, etc., or they can be films with a certain color, such as gray EVA film, gray TPU film, gray PVB film, etc.

[0032] Furthermore, such as Figure 2 As shown, the non-dimming area 12 is an extension of the first transparent substrate 1-1 of the dimming area 11.

[0033] Specifically, such as Figure 3 As shown, the controller 2 and the side window dimming glass 1 are fixed by the base 3.

[0034] This invention fixes the controller 2 to the surface of the side window dimming glass 1. During the up-and-down movement of the side window dimming glass of a passenger vehicle, it avoids the potential safety risks caused by the movement of the high-voltage wiring harness that is electrically connected between the controller 2 and the side window dimming glass 1, and has good practical value.

[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
