[0002] With the continuous development of automobile technology, in-vehicle information display systems are also constantly improving. Traditional in-vehicle information display systems usually adopt a split design, that is, different functional modules (such as navigation, audio control, vehicle speed, etc.) are scattered in different positions of the dashboard. This design method not only takes up a lot of space on the dashboard, but also has certain limitations in terms of visual effects and user experience.

[0003] In recent years, the long-linked screen (also known as "cross-type" or "integrated" display screen) technology has gradually become a new trend in vehicle information display systems. The long-linked screen integrates multiple functional modules into a larger display screen, which improves the convenience of information display and the user's driving experience.

[0004] However, the long screen currently used in vehicles is usually set above the dashboard, which destroys the integrity of the dashboard to a certain extent. In addition, due to this arrangement, the interior design of the vehicle behind the long screen will be blocked, which not only affects the driver's field of vision, but also reduces the aesthetics of the interior of the vehicle.

[0005] Therefore, it is necessary to provide a display component that can not only expand the occupants' forward field of view, but also does not affect the vehicle's front information display and the integrity and aesthetics of the vehicle's interior design, thereby improving the user experience.

[0031] The implementation and use of specific embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are only exemplary of specific ways to implement and use the present invention, rather than limiting the scope of the present invention.

[0032] In this specification, when describing the structural position of each component, directional expressions such as "upper", "above", etc. are not absolute, but relative. When the components are arranged as shown in the figure, these directional expressions are appropriate, but when the position of the components in the figure changes, these directional expressions should also change accordingly. In addition, "inner" is defined with reference to the inside and outside direction relative to the vehicle, for example, "inside" refers to the side facing the inside of the vehicle.

[0033] In this document, unless otherwise specified or limited, the terms "installation", "arrangement" and the like should be understood in a broad sense. For example, it can be fixed installation, detachable installation, or integrated installation; it can be direct installation or indirect installation through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0034] In this article, "front" and "rear" are relative to the longitudinal direction of the vehicle. In addition, "lateral" refers to the direction of the vehicle's relatively smaller size, which can also be called the width direction, and "longitudinal" refers to the direction of the vehicle's relatively larger size, which can also be called the length direction, and also indicates the direction of travel.

[0035] The following uses Figures 1 to 8 To describe the preferred embodiment of the present utility model.

[0036] The display system of the vehicle according to the utility model includes a display component 1 and a projection device 2, wherein the projection device 2 is used to project projection light onto the display component 1, that is, the projection device 2 is equivalent to a light source, and the display component 1 is used to reflect the projection light to the user. In addition, the display component 1 can also transmit ambient light. In some embodiments, the projection device 2 can be integrated with the electronic control unit (ECU) or vehicle body controller (VCU) of the vehicle to provide real-time vehicle information. The vehicle information provided by the projection device 2 can include, for example, the vehicle's speed, mileage, fuel level, remaining power, warning information, navigation, etc. Figure 4 For example, the projection device 2 is installed in a recess 31 on the top of the dashboard 3 of the vehicle, which is away from the occupant along the longitudinal direction, that is, in the recess 31 between the back side of the top of the dashboard 3 and the front windshield 4 of the vehicle, and the display assembly 1 is installed on the dashboard 3 between the recess 31 and the front windshield 4 (such as Figure 7 As shown in the dashed box A in FIG. 1 , the occupant can see the following through the display assembly 1: Figure 4 In this way, the passengers on the display side of the display assembly 1 can not only see the projected image presented by the projection light from the projection device 2, but also see the external environment of the vehicle through the display assembly 1.

[0037] The following will refer to Figures 1 to 3 The structure of the display assembly 1 will be described in detail.

[0038] like Figure 1 As shown, a display assembly 1 according to an embodiment of the present invention includes a semi-transmissive and semi-reflective layer 11, a dimming layer 12 with variable transmittance, a transparent substrate 13, and a dimming layer transmittance control unit (not shown). The semi-transmissive and semi-reflective layer 11, the dimming layer 12, and the transparent substrate 13 are stacked in sequence along the viewing direction, the semi-transmissive and semi-reflective layer 11 is located above the dimming layer 12, and the transparent substrate 13 is located below the dimming layer 12. The semi-transmissive and semi-reflective layer 11 reflects the projection light from the projection device 2 to present the projection image from the projection device 2 to the occupants. Figure 4 In the case shown, the semi-transparent and semi-reflective layer 11 is arranged on the side facing the occupant. Alternatively, the transparent substrate 13 can also be a non-transparent substrate. The transparent substrate 13 is also used to receive ambient light and transmit ambient light. Figure 4 In the illustrated case, the transparent substrate 13 is arranged on the side facing the front windshield 4. The dimming layer 12 receives the ambient light from the transparent substrate 13 and transmits the received ambient light under variable transmittance, and the semi-transmissive and semi-reflective layer 11 receives the ambient light from the dimming layer 12 in addition to reflecting the projection light and transmits the received ambient light, so that the occupant can see the external environment of the vehicle through the display assembly 1.

[0039] In this way, the display component 1 according to the present embodiment can enable the occupants to see the reflected vehicle information and the transmitted external environment of the vehicle through the display component 1. The dimming layer 12 has a variable transmittance, and the transmittance of the display component 1 to ambient light can be adjusted as needed. When the variable transmittance is low, a better contrast of the projected image is achieved, and the influence of ambient light on the projection display effect is reduced. When the variable transmittance is high, the transparency of the display component 1 is high, which does not affect the field of vision of the occupants and improves the user experience. In addition, since the projection device 2 projects the image onto the display component 1 and the display component 1 is independently arranged in the vehicle, the arrangement position and shape of the display component 1 are not limited by components such as the front windshield 4, as long as the projected image can be displayed to the occupants.

[0040] In some embodiments, the dimming layer transmittance control unit is electrically connected to the dimming layer, that is, the dimming layer 12 can adjust the variable transmittance under the control of the electrical signal. In this case, the variable transmittance can be adjusted by the dimming layer transmittance control unit, and the dimming layer transmittance control unit can send an electrical signal to the dimming layer 12 according to the user's adjustment needs or automatically. For example, when the dimming layer transmittance control unit sends an electrical signal according to the user's adjustment needs, the user can select the desired variable transmittance on the interactive component to send an adjustment instruction to the dimming layer transmittance control unit, and the dimming layer transmittance control unit sends an electrical signal to the dimming layer 12 based on the adjustment instruction. In some embodiments, the interactive component can be a touch screen, such as a central control screen of a vehicle, or a button, such as a rotary button, etc., which is not limited here. When the dimming layer transmittance control unit automatically sends an electrical signal, the dimming layer transmittance control unit can automatically adjust the variable transmittance according to the brightness of the ambient light. For example, when the brightness of the ambient light is high, the dimming layer transmittance control unit can reduce the variable transmittance, and when the brightness of the ambient light is low, the dimming layer transmittance control unit can increase the variable transmittance to improve the display effect of the projected image. It can be understood that the adjustment method of the variable transmittance is not limited to this, and the dimming layer 12 can also adjust the variable transmittance under the control of a magnetic signal or mechanical control, for example.

[0041] like Figure 2 As shown, according to another embodiment, the display assembly 1 may further include a texture layer 14, which may be located between the dimming layer 12 and the transparent substrate 13, and the texture layer 14 may, for example, display wood texture, stone texture, water texture, etc. In this way, when the variable transmittance of the dimming layer 12 is high, the display assembly 1 may be used as a decorative part, displaying the texture of the texture layer 14, and improving the aesthetics of the vehicle interior design.

[0042] like Figure 3 As shown, according to another embodiment, the display assembly 1 may further include a backlight layer 15, which may be located between the texture layer 14 and the transparent substrate 13, and the backlight layer 15 may provide a lighting effect. In this way, when the variable transmittance of the dimming layer 12 is high, the display assembly 1 may display a texture with a lighting effect, further improving the decorative effect of the display assembly 1 and the aesthetics of the vehicle interior design.

[0043] In some embodiments, the variable transmittance may include a first transmittance and a second transmittance. The first transmittance may be a low transmittance of the dimming layer 12, at which the dimming layer 12 can be dimmed to a dark color. The first transmittance may be in the range of 1% to 50%. The second transmittance may be a high transmittance of the dimming layer 12, at which the dimming layer 12 can be dimmed to a light color or a transparent state. The second transmittance may be in the range of 3% to 90%. In addition, the first transmittance should be less than the second transmittance. For example, the first transmittance may be 5% and the second transmittance may be 35%. It is understood that the value range of the variable transmittance is not limited thereto and may be changed as required. In some embodiments, the semi-transparent and semi-reflective layer 11 may reflect the projection light from the projection device 2 within a reflectivity range of 10% to 50%. For example, the reflectivity may be 35%. It is understood that the value range of the reflectivity of the semi-transparent and semi-reflective layer 11 is not limited thereto and may be changed as required.

[0044] In some embodiments, the display component 1 can be configured as a curved surface. In this way, the display component 1 can be integrated with the interior design of the vehicle, and can more naturally adapt to the curve of the human eye when the user is watching, reducing visual fatigue. It is understandable that the configuration of the display component 1 is not limited to this, and the display component 1 can also be configured as a plane, a combination of planes and planes, or a combination of planes and curved surfaces, etc. Additionally, the display component 1 can be made of a flexible material, which can better adapt to curved or irregularly shaped surfaces, reduce the thickness of the display component 1, make it occupy less space, and save space inside the vehicle.

[0045] In addition, the stacked layers in the display assembly 1 may be bonded together by gluing or electrostatic bonding, etc., which is not limited in the embodiments of the present invention.

[0046] The following will refer to Figures 5 to 8 Other exemplary arrangements of the display system are described.

[0047] like Figure 5 and Figure 7 As shown, the display system can also be arranged on the side of the vehicle's dashboard 3 facing the occupant, that is, Figure 7 Specifically, the projection device 2 can be disposed on the platform 32 of the dashboard 3 of the vehicle facing the passenger, and the display assembly 1 can be disposed on the dashboard 3 above the projection device 2, so that the user can see the vehicle information presented by the display assembly 1 more clearly at a close distance.

[0048] like Figure 6 and Figure 8 As shown, the display system can also be arranged on the inner side of the door panel of the vehicle, that is, Figure 8Specifically, the projection device 2 can be arranged on the door panel 5 of the vehicle, and the display assembly 1 can be arranged on the door panel 5 above the projection device 2. In particular, the projection device 2 can be arranged on the armrest 51 of the door panel 5 of the vehicle, and the display assembly 1 can be arranged as shown in FIG. Figure 8 The front end of the door panel 5 is shown at the circle D. In this way, the display assembly 1 can also be used as an electronic exterior rearview mirror. In this case, the display system can be arranged at the door panels on both sides of the vehicle facing the driver and the co-driver, and the projection device 2 can project the image of the vehicle's external environment, so that the driver can reduce the blind spot when turning, reversing, etc., and improve driving safety.

[0049] In the above two arrangement positions, the display assembly 1 can be Figure 2 and Figure 3 The display assembly shown in the figure, when there is no need to display the projected image, the display assembly 1 can be used as a decorative piece to improve the aesthetics of the vehicle interior design.

[0050] It should be understood that the embodiments shown in the figures only show optional shapes and arrangements of display components and display systems according to the present invention, but they are only for illustration and not limitation. Other shapes and arrangements may also be adopted without departing from the concept and scope of the present invention.
