Description

Technical Field

[0001] This utility model relates to the field of automotive instrument display technology, and in particular to a panoramic display device and a new energy vehicle. Background Technology

[0002] More and more car models are adopting slim instrument panels or eliminating them altogether by replacing them with PHUD (panoramic head-up display) systems. This allows drivers to focus their attention on the road while simultaneously seeing road conditions and driving information, thus improving safer driving. PHUD is a new type of reflective imaging system that projects the display image onto a black silkscreened area at the bottom of the windshield. However, PHUD works on the principle of reflecting a virtual image, which results in image distortion, parallax, astigmatism, and field curvature. Furthermore, during the day, to ensure display quality, PHUD consumes a lot of power and generates significant heat.

[0003] For example, CN103754162A discloses an automotive head-up display system and a car, which uses a flexible OLED display adhered to the windshield and employs the self-emissive display method of the flexible OLED display to display instrument panel information, achieving the goals of low power consumption, no viewing angle limitation, and good display effect. However, since the flexible OLED display is directly adhered to the windshield without any light-shielding components, it still requires high brightness during the day, and the problems of poor display effect and high power consumption persist.

[0004] Therefore, a panoramic display device and a new energy vehicle are proposed to solve the technical problems of existing technologies that do not provide light-shielding components for flexible OLED displays, resulting in flexible OLED displays still requiring high brightness during the day and still having poor display effects and high power consumption. Utility Model Content

[0005] In view of this, this utility model proposes a panoramic display device and a new energy vehicle, which improves the display effect of the display unit by configuring a light-shielding component, and solves the technical problems of poor display effect and high power consumption in the existing solution.

[0006] This utility model proposes a panoramic display device, comprising: A sunshade and display unit installed on the windshield of a car, and a cockpit domain controller installed on the car; The light-shielding element is located on the side of the windshield closest to the vehicle's dashboard; The display unit is located on the side of the windshield near the vehicle dashboard and on the side of the shading member near the vehicle interior. The projection of the display unit on the surface of the shading member coincides with the shading member. The display unit is electrically connected to the cockpit domain controller and is used to display vehicle instrument information.

[0007] Based on the above technical solution, preferably, the light-shielding component and the display unit are flush with both sides of the windshield in the width extension direction of the vehicle.

[0008] Based on the above technical solution, preferably, in the direction of the vehicle's height extension, the length of the light shield protruding from the display unit does not exceed 10mm.

[0009] Based on the above technical solution, preferably, the display unit is made of a flexible material and is attached to the windshield along the curvature of the windshield.

[0010] Based on the above technical solution, preferably, the light-shielding component is a screen-printed film, and the color of the light-shielding component is black or dark gray.

[0011] Based on the above technical solution, preferably, the angle between the plane where the display unit is located and the vertical plane is in the range of 0~15°.

[0012] Based on the above technical solution, preferably, the windshield has a first layer, a second layer and a third layer arranged in sequence, the first layer being located outside the vehicle and the third layer being located inside the vehicle; The light-shielding element is disposed between the first layer and the second layer; The display unit is disposed between the second layer and the third layer or on the side of the third layer away from the second layer.

[0013] Based on the above technical solution, preferably, when the display unit is disposed on the side of the third layer away from the second layer, a protective coating is disposed on the display surface of the display unit.

[0014] Based on the above technical solution, preferably, it also includes a flexible printed circuit board, and the display unit is electrically connected to the cockpit domain controller through the flexible printed circuit board.

[0015] On the other hand, this utility model also provides a new energy vehicle, which is equipped with the aforementioned panoramic display device.

[0026] The technical solution is explained below. Existing flexible OLED displays are directly adhered to the windshield without any light-shielding components. This results in the flexible OLED displays still requiring high brightness during the day, and still suffering from poor display quality and high power consumption. Therefore, if... Figure 1 As shown, this utility model provides a panoramic display device, including: A light shield 1 and a display unit 2 installed on the windshield 100 of a car, and a cockpit domain controller 3 installed on the car; The sunshade 1 is located on the side of the windshield 100 near the dashboard of the vehicle; The display unit 2 is located on the side of the windshield 100 near the dashboard and on the side of the shading 1 near the interior of the vehicle. The projection of the display unit 2 onto the surface of the shading 1 coincides with the shading 1. The display unit 2 is electrically connected to the cockpit domain controller 3 and is used to display vehicle instrument information.

[0027] The display unit 2 is located at the bottom of the windshield 100, and a light shield 1 is disposed on the back of the display unit 2 to prevent the light from the display unit 2 from being affected by external light, thus ensuring the display effect of the display unit 2. It is worth mentioning that, from the driver's perspective inside the car, when the driver can view the displayed information through the display unit 2, the projection of the display unit 2 onto the surface where the light shield 1 is located coincides with the light shield 1, so the display unit 2 is not affected by external light, ensuring that the driver can effectively view the information.

[0028] like Figure 2 As shown, in order to ensure that the display unit 2 has a sufficient display area, the light shield 1 and the display unit 2 are flush with the sides of the windshield 100 in the width extension direction of the vehicle.

[0029] Display unit 2 extends from the A-pillar on one side of the car to the A-pillar on the other side of the windshield 100. Display unit 2 can provide a panoramic view, and the display effect is not affected by the external environment. The huge display area and excellent display effect on the windshield 100 of the car bring the driver an unprecedented sense of immersion and technology.

[0030] like Figure 2 As shown, in order to ensure the blocking effect of the shading member 1, the length of the shading member 1 protruding from the display unit 2 in the height extension direction of the vehicle does not exceed 10mm.

[0031] A 10 mm gap is left between the upper edge of the display unit 2 and the light shield 1 on the windshield 100, which can effectively prevent external ambient light from affecting the display effect of the display unit 2. In addition, since the light shield 1 is opaque, if the length of the light shield 1 protruding from the display unit 2 is too long when the driver is sitting in the driver's seat, it will affect the driver's vision. Therefore, the length of the light shield 1 relative to the display unit 2 is limited to effectively prevent the light shield 1 from affecting the driver's vision.

[0032] like Figure 1 As shown, the observation areas of the driver's horizontal and downward lines of vision are illustrated. The display unit 2 is located below the lower line of vision of the instrument panel. During normal driving, the content in the display unit 2 will not affect the view in the windshield 100. The driver can see the content in the display unit 2 through eye movements. The driver does not need to look down at the instrument panel significantly. Furthermore, when looking at the instrument content in the display unit 2, the driver can observe at least part of the area in the windshield 100, thus ensuring safety during driving.

[0033] like Figure 1 As shown, in order to ensure the display effect of the display unit 2, the display unit 2 is made of flexible material and is attached to the windshield 100 along the curvature of the windshield 100.

[0034] Display unit 2 is configured as a flexible OLED display screen, which is located at the bottom of the windshield 100. The display effect is the same as that of an OLED display screen and is not affected by the surrounding environment.

[0035] To ensure that the light-shielding component 1 has a light-shielding effect and to enhance the dark display background of the display unit 2, the light-shielding component 1 is a screen-printed film, and the color of the light-shielding component 1 is black or dark gray.

[0036] The light-shielding element 1 can be a film screen-printed part, for example, the film screen-printed part can be a film with a black or dark gray color; the film is laminated or glued onto the windshield 100, and laminating the film onto the windshield 100 has the advantage of low cost.

[0037] like Figure 5As shown, in order to avoid the display content of the display unit 2 being degraded due to the driver's viewing position, the angle α between the plane where the display unit 2 is located and the vertical plane is in the range of 0~15°.

[0038] Specifically, the viewpoint of the driver observing the display unit 2 varies depending on their height. By limiting the angle between the display unit 2 and the vertical plane, it can be ensured that the driver can clearly observe the content displayed on the display unit 2.

[0039] More specifically, the display unit 2 is designed to be as flat as possible, so as to avoid the problem of squint caused by different viewing positions of the driver.

[0040] like Figure 3 As shown, the windshield 100 has a first layer 110, a second layer 120 and a third layer 130 arranged sequentially, with the first layer 110 located on the exterior of the vehicle and the third layer 130 located on the interior of the vehicle. The light-shielding element 1 is disposed between the first layer 110 and the second layer 120; The display unit 2 is located between the second layer 120 and the third layer 130 or on the side of the third layer 130 away from the second layer 120.

[0041] Specifically, the display unit 2 is located between the second layer 120 and the third layer 130 of the windshield 100, that is, between the middle layer and the innermost layer of the windshield 100. This allows the display unit 2 to be integrated into the windshield 100, so that the display unit 2 can avoid external influences, effectively avoid scratches, and extend its service life.

[0042] like Figure 4 As shown, this utility model also provides another embodiment, in which the display unit 2 is set on the side of the third layer 130 away from the second layer 120, that is, the display unit 2 is directly set on the innermost layer of the windshield 100 close to the vehicle interior. This allows the display unit 2 to display the image clearly, and it can be quickly replaced when the display unit 2 malfunctions and needs maintenance.

[0043] like Figure 4 As shown, when the display unit 2 is located on the side of the third layer 130 away from the second layer 120, a protective coating is provided on the display surface of the display unit 2. The protective coating can be glass or transparent resin. Preferred, the protective coating is configured as POSS resin, which can simultaneously improve the water and oxygen resistance, scratch resistance and impact resistance of the display unit 2, and extend its service life.

[0044] like Figure 2 As shown, in order to ensure stable display of the display unit 2, the aforementioned panoramic display device also includes a flexible printed circuit board 4, and the display unit 2 is electrically connected to the cockpit domain controller 3 through the flexible printed circuit board 4.

[0045] The flexible printed circuit board 4, with polyimide or polyester as the substrate, has the characteristics of high flexibility, thinness and foldability. It transmits information such as vehicle speed, RPM and fuel consumption from the cockpit domain controller 3 to the display unit 2. The flexibility of the flexible printed circuit board can adapt to the complex spatial layout inside the instrument panel and improve the freedom of automotive design.

[0046] The working principle of this panoramic display device is to apply a flexible OLED display to the screen-printed film area at the bottom of the windshield, so that the display effect of the flexible OLED display is not affected by the external environment, giving the driver an excellent viewing experience without having to look down at the car's dashboard. In addition, the flexible OLED display is 100mm wide, the same as the entire windshield, and can realize a panoramic display from one A-pillar to the other in the car. The huge display space can integrate electronic rearview mirrors, driving information and entertainment information.

[0047] On the other hand, this utility model also provides a new energy vehicle equipped with the aforementioned panoramic display device. The display surface of the display unit 2 faces the driver's seat, allowing all information from the traditional instrument panel to be displayed on the display unit 2. When the driver is in the driving position, they do not need to look down at the instrument panel. While obtaining external road condition information from the windshield 100, they can also see information such as vehicle speed, RPM, and fuel consumption, thereby improving driver safety. Furthermore, because the display unit 2 has a larger display space than a traditional instrument panel, at least a portion of the display unit 2 can display information from both sides of the vehicle, providing the driver with a comprehensive view of the vehicle and assisting in better driving.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
