Description
Technical Field
[0001] This utility model relates to the fields of vehicles and construction, and specifically to window glass components. Background Technology
[0002] With the development of intelligent vehicles, the interaction between vehicles and the outside world, as well as between vehicles and their occupants, is increasing, making the interface for information exchange increasingly important. Currently, transparent displays can serve as this information exchange interface. For example, transparent displays can be incorporated into vehicle window glass components for display purposes.
[0003] For vehicle occupants, the requirement is for in-vehicle displays to enable in-vehicle entertainment and vehicle settings, while for external users (such as other road users), the requirement is for external displays. Therefore, a window glass assembly that can display information from both sides of the window is needed.
[0004] There is a need to improve the window glass components. Utility Model Content
[0005] This invention provides a window glass assembly that can be applied in vehicles and buildings, achieving internal and / or external display functions by arranging various functional layers and window glass in different sequences.
[0006] According to an embodiment, the window glass assembly includes window glass, inner and outer displays, and a dimming film. The outer display is constructed as a transparent display film configured to switch between a transparent mode and an operating mode. In the transparent mode, the transparent display film is transparent; in the operating mode, the transparent display film can display visual content (e.g., via a control module). The dimming film is configured to switch between a transparent mode and a non-transparent mode. In the transparent mode, the dimming film is transparent, and its transparency is adjustable (e.g., according to user needs); in the non-transparent mode, the dimming film is opaque. The transparent display film and the dimming film are coordinated and controlled such that when the transparent display film is in the operating mode, the dimming film switches to the non-transparent mode, and when the transparent display film is in the transparent mode, the dimming film switches to the transparent mode. According to this invention, the inner and outer displays are independent displays, and the dimming film is arranged between the inner and outer displays; or the inner and outer displays are composed of the same transparent display film, and the window glass assembly includes two dimming films, with the transparent display film arranged between the two dimming films.
[0007] Preferably, the window glass assembly further includes two touch films, which are respectively associated with the inner and outer displays. The transparent display film and the dimming film are arranged between the two touch films, or the window glass, the transparent display film, and the dimming film are all arranged between the two touch films. This arrangement provides touch functionality to both the inner and outer displays.
[0008] According to an embodiment, when the inner and outer displays are independent displays, the inner display may also be constructed as a transparent display film or as a projection display, such as a head-up display (HUD).
[0009] According to one embodiment, the window glass assembly includes two layers of window glass, which are respectively disposed on the outermost and innermost sides of the window glass assembly. According to another embodiment, it includes only one layer of window glass, which is disposed between the dimming film and the transparent display film or between the dimming film and a touch film on one side.
[0010] According to one embodiment, both the inner and outer displays are constructed as transparent display films, and two touch films are respectively disposed between the inner and outer displays and the inner and outer window glass. According to another embodiment, the two touch films are respectively disposed between the inner and outer dimming films and the inner and outer window glass.
[0011] According to one embodiment, both the inner and outer displays are constructed as transparent display films, with two touch films respectively disposed on the outermost and innermost sides, and the window glass and dimming film located between the two transparent display films. According to another embodiment, the two touch films are respectively disposed on the outermost and innermost sides, and the window glass and transparent display film are located between the two dimming films. According to yet another embodiment, the inner display is constructed as a projector, which is disposed on the outermost side, with two touch films respectively disposed on the outermost and second innermost sides, and the dimming film located between the window glass and the outer display.
[0012] According to this utility model, the various functional layers and window glass of the window glass assembly can be arranged according to different user requirements to optimize the thickness of the window glass assembly.
[0013] The window glass assembly of this invention can realize different interactive interfaces on the same window glass according to different user requirements. Attached Figure Description

[0019] Figure 5 This is a schematic diagram of the vehicle window glass assembly according to the fifth embodiment of this utility model. Detailed Implementation
[0020] The following describes several embodiments of the present invention in detail with reference to the accompanying drawings.
[0021] Figure 1 The window glass assembly 1 according to the first embodiment is shown, which has two layers of window glass 10, two layers of transparent display film 20 as a display screen, two layers of touch film 30 and one layer of dimming film 40. As shown, the dimming film 40 is disposed between the two layers of transparent display film 20, and each layer of touch film 30 is disposed between the corresponding window glass 10 and transparent display film 20, such that from the outside of the vehicle O to the inside of the vehicle I, the window glass 10, touch film 30, transparent display film 20, dimming film 40, transparent display film 20, touch film 30 and window glass 10 are laminated or bonded together to form the window glass assembly 1.
[0022] The transparent display film 20 and the dimming film 40 are coordinated and controlled so that when the transparent display film 20 is working, the dimming film 40 will darken to achieve a better display effect, and when the transparent display film 20 is not working, the dimming film 40 will become transparent so that the occupants inside the vehicle can see the outside scenery. The transparency of the dimming film 40 can be adjusted according to the user's needs. In addition, the dimming film 30 also has a certain blocking effect on infrared and ultraviolet rays. Therefore, the window glass assembly 1 can also protect the occupants inside the vehicle from sunburn.
[0023] The advantage of the first embodiment is that two separate transparent display films 20 can be configured to display different information to users outside the vehicle and occupants inside the vehicle, and the outer glass 10 and inner glass 10 can protect the various functional films inside. However, the disadvantage of this embodiment is that the assembly process is relatively complex because each film needs to be bonded or laminated. Moreover, the overall thickness of the window glass assembly is relatively thick due to the additional thickness introduced by the lamination or bonding process.
[0024] Figure 2The window glass assembly 100 according to the second embodiment is shown, which has only one layer of window glass 110, two layers of transparent display films 120 as a display screen, two layers of touch films 130 and one layer of dimming film 140. As shown, the dimming film 140 is disposed between the two layers of transparent display films 120, each layer of transparent display film 120 is disposed between the corresponding touch film 130 and dimming film 140, and the window glass 110 is disposed between the dimming film 140 and one of the transparent display films 120 (e.g., the transparent display film 120 on the exterior side O), such that from the exterior O to the interior I, the sequence is touch film 130, transparent display film 120, window glass 110, dimming film 140, transparent display film 120, and touch film 130, which are laminated or bonded together to form the window glass assembly 100.
[0025] Similar to the first embodiment, the advantage of the second embodiment is that the two separate transparent display films 120 can display different information to users outside the vehicle and occupants inside the vehicle. Additionally, compared to the first embodiment, the window glass assembly 100 is thinner and the assembly process is easier. However, a disadvantage of this embodiment is that additional protective measures are needed to prevent scratches on the touch film 130.
[0026] Figure 3 The window glass assembly 100 according to the third embodiment is shown, which has two layers of window glass 210, only one layer of transparent display film 220 as a display screen, two layers of touch film 130 and two layers of dimming film 240. As shown, the transparent display film 220 is disposed between the two layers of dimming film 240, each layer of dimming film 240 is disposed between the corresponding touch film 230 and the transparent display film 220, and each layer of touch film 230 is disposed between the corresponding window glass 210 and the dimming film 240, such that from the outside of the vehicle O to the inside of the vehicle I, the sequence is window glass 210, touch film 230, dimming film 240, transparent display film 220, dimming film 240, touch film 230 and window glass 210, which are laminated or bonded together to form window glass assembly 200.
[0027] Similar to the first embodiment, the advantage of the third embodiment is that the outer and inner glass layers 210 can protect the various internal functional films. On the other hand, compared to the first embodiment, the window glass assembly 200 is lighter due to the lower weight of the dimming film 240. Furthermore, the window glass assembly 200 is thinner than the first embodiment due to the smaller thickness of the dimming film 240. Additionally, the cost of the window glass assembly 200 is lower than the first embodiment due to the lower cost of the dimming film 240. However, the disadvantage of this embodiment is that since there is only one transparent display film 220, it is impossible to simultaneously perform exterior and interior displays. Moreover, the video quality of the transparent display film 220 may differ between its front and back sides, resulting in potentially different quality levels for exterior and interior displays. Furthermore, the assembly process is more complex because each film requires bonding or lamination.
[0028] Figure 4 A window glass assembly 300 according to a fourth embodiment is shown, which has only one layer of window glass 310, only one layer of transparent display film 320 as a display screen, two layers of touch film 330, and two layers of dimming film 340. As shown, the transparent display film 320 is disposed between the two layers of dimming film 340, each layer of dimming film 340 is disposed between the corresponding touch film 330 and the transparent display film 320, and the window glass 310 is disposed between the transparent display film 320 and one of the dimming films 340 (e.g., the dimming film 340 on the exterior side O), such that from the exterior O to the interior I, the sequence is touch film 330, dimming film 340, window glass 310, transparent display film 320, dimming film 340, and touch film 330, which are laminated or bonded together to form the window glass assembly 300.
[0029] Compared to the third embodiment, the window glass assembly 300 is thinner and easier to assemble. However, like the second embodiment, this embodiment has the disadvantage that additional protective measures are needed to prevent the touch film 330 from being scratched. Furthermore, like the third embodiment, this embodiment cannot simultaneously display external and internal information. Additionally, the video quality of the transparent display film 320 may differ between its front and back sides.
[0030] Figure 5A window glass assembly 400 according to a fifth embodiment is shown, comprising only one layer of window glass 410, only one layer of transparent display film 420 as a display screen, two layers of touch film 430, and only one layer of dimming film 440. As shown, the transparent display film 420 is disposed between the touch film 430 and the dimming film 440 on the exterior (O) side of the vehicle, the dimming film 440 is disposed between the transparent display film 420 and the window glass 410, and the window glass 410 is disposed between the touch film 430 and the dimming film 440 on the interior (I) side of the vehicle, such that from the exterior (O) to the interior (I), the sequence is touch film 430, transparent display film 420, dimming film 440, window glass 410, and touch film 430, which are laminated or bonded together to form the window glass assembly 400. In this example, the transparent display film 420 is used only for exterior display, and interior display is achieved through an in-vehicle projector C or HUD.
[0031] The advantage of the fifth embodiment is that the window glass assembly 400 is thinner and the assembly process is easier compared to the third embodiment. However, the disadvantages of this embodiment are that the touch film 430 requires additional measures to prevent scratches. Moreover, the manufacturing cost is higher and more space is required due to the additional projector C.
[0032] The second to fifth embodiments operate in the same manner as the first embodiment. Specifically, the transparent display film and the dimming film are coordinated and controlled so that when the transparent display film is active, the dimming film becomes opaque for display purposes, and when the transparent display film is inactive, the dimming film becomes transparent to allow normal light transmission through the window glass. The transparency of the dimming film can also be adjusted according to the user's needs.
[0033] The embodiments of this invention have been described above for vehicle window glass assemblies. It is understood that the window glass assembly of this invention can also be applied to buildings.
[0034] Through the above description of the disclosed embodiments, those skilled in the art will be able to implement or use the present invention. Various modifications to these embodiments will also be apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein, but covers the widest scope consistent with the principles disclosed herein.
