[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0027] The present invention provides a method for arranging transparent A-pillar screens in automobiles. By finding the blind spots of the left A-pillar 110 and the right A-pillar 120 from the driver's viewpoint 5, the left obstacle 6 and the right obstacle 7 are placed in the blind spots on both sides respectively. The positions of the left and right LED screens 2 relative to the left A-pillar 110 and the right A-pillar 120 are adjusted so that the obstacles on the left and right sides are placed within the driver's field of vision.

[0028] In this invention, the driver's field of view is the visible range between the upper field of view line 51 and the lower field of view line 52. The upper field of view line 51 is the extension of the line connecting the driver's viewpoint 5 and the upper edge of the LED screen 2. The lower field of view line 52 is the extension of the line connecting the driver's viewpoint 5 and the lower edge of the LED screen 2.

[0029] In this invention, the LED screen 2 on the right A-pillar 120 is positioned lower than the LED screen 2 on the left A-pillar 11. The edges of the LED screen 2 are mounted and fixed to the A-pillar guard plates 1 on both sides via screen clamping plates 3.

[0030] This type of car A-pillar arrangement features LED screens 2 on both the left and right A-pillar panels 1. The LED screen 2 on the right A-pillar 120 is positioned lower than the LED screen 2 on the left A-pillar 110. Because obstacles of the same size (obstacle 6 on the left and obstacle 7 on the right) are located in the A-pillar blind spot area, the obstacle can be displayed on the left A-pillar screen for the driver to see, but the obstacle cannot be displayed on the right A-pillar screen, making it impossible for the driver to see obstacles in the left A-pillar blind spot area. Figures 1 to 9 As shown in the diagram, analysis based on the driver's field of vision indicates that setting the right-side LED screen to a lower position helps to better display obstacles in the right-side blind spot, thereby improving safety performance.

[0031] A car with asymmetrically arranged transparent A-pillars was designed. This allows obstacles of the same size within the blind spot of the A-pillars to be displayed better in real time on both the left and right transparent A-pillar screens, enabling the driver to observe and take evasive action, thus avoiding traffic accidents.

[0032] Taking a left-hand drive vehicle as an example, because the screen on the left A-pillar 110 is closer to the driver, obstacles 6 in the left-side blind spot of the left A-pillar can basically be displayed on the left screen and observed by the driver. If the screen on the right A-pillar 120 is symmetrical to the left, because the screen on the right A-pillar 120 is farther away from the left, obstacles in the right-side blind spot are difficult to display on the screen. By placing the LED screen 2 on the right A-pillar 120 at a lower position, obstacles in the right-side blind spot can be better displayed on the LED screen 2 on the right, achieving synchronous display on both sides to improve vehicle driving safety.

[0033] Figure 1 This diagram illustrates the position of the screen on the right A-pillar and the driver's field of vision. The upper field of vision line 51 is the extension of the line connecting the driver's viewpoint 5 to the upper edge of the LED screen on the right A-pillar, and the lower field of vision line 52 is the extension of the line connecting the driver's viewpoint 5 to the lower edge of the LED screen on the right A-pillar. Because the left A-pillar is closer to the driver, the screen on the left A-pillar can be positioned relatively higher.

[0034] Figure 2 This diagram illustrates the position of the left A-pillar screen and the driver's field of vision when the right A-pillar 120 and the left A-pillar 110 are designed symmetrically, and the screen positions on the right and left A-pillars are also symmetrical. The upper field of vision line 51 in the diagram is the extension of the line connecting the driver's viewpoint 5 to the upper edge of the LED screen 2 on the right A-pillar 120, and the lower field of vision line 51 is the extension of the line connecting the driver's viewpoint 5 to the lower edge of the LED screen 2 on the right A-pillar 120. The screens on the right and left A-pillars are symmetrically arranged with respect to the vehicle's centerline. In this configuration, obstacles of the same specifications as those on the left are not within the driver's field of vision and cannot be displayed.

[0035] Figure 3 The right A-pillar 120 and the left A-pillar 110 are designed symmetrically, but the screen positions of the right A-pillar and the left A-pillar are not symmetrical. This is a schematic diagram of the screen position of the left A-pillar and the driver's field of vision. Figure 3 The LED screen 2 on the right A-pillar 120 is positioned significantly lower than the LED screen 2 on the left A-pillar 120.

[0036] Figure 4 , Figure 5This is a top-down view of the blind spots and obstacles observed from the driver's perspective when viewing the left and right A-pillar screens. In this embodiment, the obstacle in the A-pillar blind spot is a cylinder with a height H = 1000 mm and a diameter D = 300 mm, used to simulate a child's body. The distance between the obstacle and the vehicle in the figure is L = 1000 mm. The distance L from the vehicle is determined based on the range of the obstacle observed through the transparent A-pillar screen. In this embodiment, when L = 1000 mm, the top of the cylindrical obstacle should be visible, simulating the child's head, to ensure the driver can see the child in the A-pillar blind spot through the transparent A-pillar screen, reducing the occurrence of traffic accidents. In this embodiment, when L = 1500 mm, while the obstacle is still a cylinder with a height H = 1000 mm and a diameter D = 300 mm simulating a child's body, one-third of the cylinder's height needs to be observed. That is, the farther the obstacle is from the vehicle, the larger the range of the obstacle visible through the transparent A-pillar screen.

[0037] Figure 6 The image shows a side view of an obstacle viewed through the driver's left A-pillar screen. As can be seen, within the blind spot created when viewing the obstacle through the driver's left A-pillar, the obstacle lies within the area defined by the upper and lower lines of vision. In other words, the obstacle can be displayed on the screen through the left A-pillar and observed by the driver.

[0038] Figure 7 When the right A-pillar screen is symmetrical to the left, the driver's viewpoint observes the side view of the obstacle through the field of vision line of the right A-pillar screen. The transparent A-pillar screen through which the field of vision line passes in the diagram is derived symmetrically from the left A-pillar screen along the vehicle's centerline. Figure 2 As shown in the diagram, within the blind spot created when observing the left A-pillar from the driver's perspective, the obstacle is located below the lower field of vision. This means that obstacle 7 on the right cannot be displayed on the screen within the right A-pillar area and cannot be observed by the driver.

[0039] Figure 8 When the right A-pillar screen is asymmetrical with the left, the LED screen on the right A-pillar is positioned lower, allowing the driver to observe the side view of the obstacle through the field of vision of the right A-pillar screen. As shown in the diagram, within the blind spot created when observing the right A-pillar from the driver's perspective, the obstacle lies within the area of ​​the upper field of vision 51 and the lower field of vision 52. This means that the obstacle 7 on the right can be displayed on the screen of the right A-pillar 120 and observed by the driver.

[0040] Figure 9 for Figure 8The image shows a magnified view of the obstacle within the upper and lower field of vision. As can be seen from the image, the obstacle extends beyond the lower field of vision, meaning that the obstacle can be displayed on the screen within the right A-pillar and observed by the driver.

[0041] This type of car A-pillar arrangement structure, the screen mounting structure on the car A-pillar, such as... Figure 10 , 11 As shown, an LED screen 2 is installed on the A-pillar guard plate 1, and the edge of the LED screen 2 is fixed to the A-pillar guard plate 1 by a screen clamping plate 3. This screen mounting structure on the car A-pillar facilitates installation and layout. Combined with the unique flexibility of the OLED screen 2, the OLED screen is bent to the same curvature as the A-pillar guard plate, integrating with the shape of the inner guard plate of the A-pillar, so that the OLED screen is curved on the A-pillar. This improves the aesthetics of the transparent A-pillar without affecting the display performance of the OLED screen.

[0042] In this invention, such as Figure 12 As shown, the A-pillar guard plate 1 has a screen mounting groove 12 for placing the LED screen 2. A thin felt layer 13, which contacts the LED screen 2, is provided on the bottom surface of the screen mounting groove 12. A thin felt layer 31 is provided on the contact surface of the screen pressure plate 31 that contacts the LED screen 2. Because the OLED screen 2 is relatively fragile, a thin felt layer is applied to the A-pillar guard plate 1 and the screen pressure plate 31 to prevent scratches during installation, ensuring that the OLED screen is not damaged during installation.

[0043] In this invention, the sum of the thicknesses of the LED screen 2, the protective plate thin fleece layer 13, and the pressure plate thin fleece layer 31 is the same as the depth of the screen mounting groove 12, so as to ensure that the pressure plate can be properly pressed onto the LED screen 2, preventing the screen from being damaged by excessive pressure, or the screen from being too low and the pressure plate from being unstable.

[0044] In this invention, the screen pressure plate 3 is a frame-shaped structure surrounding the four edges of the LED screen 2. It is pressed and fixed around the LED screen 2, ensuring a stable and uniform installation and preventing screen damage caused by uneven pressure.

[0045] In this invention, a pressure plate mounting groove 11 is provided on the A-pillar guard plate 1 at the outer edge of the screen mounting groove 12. The screen pressure plate 3 is placed in the pressure plate mounting groove 11, and the upper end surface of the screen pressure plate 3 is flush with the surface of the adjacent A-pillar guard plate 1 to further improve the aesthetics of this installation structure.

[0046] In this invention, the outer edge of the screen pressure plate 3 is positioned and installed on the A-pillar guard plate 1 by mounting screws 4, and the inner edge overlaps the LED screen 2, with a thin fleece layer 31 provided at the overlap. Mounting screws 4 can be arranged on all four sides of the screen pressure plate 3 to install and fix the LED screen 2. The number of fixing points can be increased or decreased according to the actual situation such as the size of the A-pillar guard plate 1 and the OLED screen 2, to ensure a secure fixation.

[0047] The OLED screen is fixed on the A-pillar by the screen pressure plate 3, which is simple, convenient and practical. It improves the aesthetics of the transparent A-pillar without affecting the display performance of the OLED screen.

[0048] During installation, the OLED screen 2 is first attached to the A-pillar guard plate 1, and then the OLED screen 2 is fixed using the screen clamping plate 3. The screen is pressed tightly by the screen clamping plate 3 and fixed to the A-pillar guard plate 1 using mounting screws 4. In this embodiment, the screen clamping plate 3 is fixed to the A-pillar using screws, but other fixing methods such as clips can also be used. Because the OLED screen 2 is relatively fragile, in order to prevent the OLED screen from being scratched during installation, a thin layer of fleece is applied to the A-pillar guard plate 1, and a thin layer of fleece is also applied to the screen clamping plate to ensure that the OLED screen is not damaged during installation.

[0049] In the accompanying drawings of this invention, the A-pillar with an OLED screen is illustrated using the left A-pillar as an example; the same applies to the right A-pillar. This screen mounting structure on the car A-pillar is simple in structure, easy to install and arrange, and aesthetically pleasing.

[0050] The present invention provides a method for arranging transparent A-pillar screens in automobiles, which facilitates installation, improves safety, and has good application prospects.

[0051] The present invention has been described above by way of example with reference to the accompanying drawings. However, the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention or any direct application to other situations shall fall within the protection scope of the present invention.
