[0002] With the increasing prevalence of vehicle electronic data, vehicles on the market are gradually adopting electronic rearview mirrors to replace traditional physical rearview mirrors. Electronic rearview mirrors are mainly electronic devices that use camera devices to capture video streams in real time and display them on the vehicle's display screen.

[0003] When it comes to driving safety, the layout of the display device in the electronic rearview mirror needs to take into account the driver's traditional observation habits with physical rearview mirrors. That is, when checking for vehicles to the left rear, the driver will look to the left side of the center console; when checking for vehicles to the right rear, the driver will look to the right side of the center console. Therefore, the display devices showing the left and right rear video streams need to be placed on the left and right sides of the vehicle body.

[0004] In some existing electronic rearview mirror solutions, wireless connection is used to transmit video streams captured by external cameras to the display screen inside the vehicle for display. However, the real-time display of video streams is related to driving safety. Considering the insufficient stability of wireless data transmission, it is difficult to meet the requirements of electronic rearview mirrors to display video streams in real time and stably.

[0038] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 The diagram shows the overall structure of the door display device in an embodiment of the present invention from a first-view perspective. Figure 2 The diagram shows the overall structure of the door display device in an embodiment of this utility model from a second perspective. Figure 3 This diagram shows the overall structure of the door display device in an embodiment of the present invention from a third-person perspective.

[0040] In this embodiment of the utility model, the door display device is disposed on the door of the vehicle and includes a data acquisition unit 1 and a rearview unit 2. The rearview unit 2 includes a rearview housing 21 and a rearview display screen 22. The rearview housing 21 has an integrally formed shell body 211 and an extension bracket 212. The extension bracket 212 has a rod-shaped structure and an internal cavity structure 2121 that passes through its end and the shell body 211. The first end of the extension bracket 212 (i.e., the end near the shell body 211) is connected to the shell body 211, and the second end (i.e., the end near the data acquisition unit 1) extends out of the vehicle. The rearview display screen 22 is disposed on the rearview housing 21. A receiving cavity is provided on the side of the door near the center console, and the bottom of the receiving cavity has an opening. The rearview housing 21 is installed in the receiving cavity, and the rearview display screen 22 is embedded in the opening. Specifically, the edge contour of the rearview display screen 22 is consistent with the edge shape of the opening.

[0041] The acquisition unit 1 is mounted on the second end of the extension bracket 212. The acquisition unit 1 includes a camera housing 11 and a camera module 12. The camera module 12 is disposed inside the camera housing 11, and its signal line passes through the cavity structure 2121 and connects to the rearview display screen 22. For example, the extension bracket 212 and the cavity structure 2121 can be found in [reference needed]. Figure 5 When the camera module 12 is working, it displays the captured video stream in real time on the rearview display screen 22. Specifically, the camera module 12 of the acquisition unit 1 is directly connected to the rearview display screen 22 of the rearview unit 2 via a signal line; the rearview housing 21 has an extension bracket 212, and the signal line passes through the cavity structure 2121 of the extension bracket 212, extends through the center console to the outside of the vehicle, and connects to the camera module 12.

[0042] The door display device in this embodiment includes a data acquisition unit 1 and a rearview unit 2. The data acquisition unit 1 is used to acquire video streams from outside the vehicle, and the rearview unit 2 is used to display the video streams acquired by the data acquisition unit 1 in real time. The rearview unit 2, located on the inside of the door (i.e., the side of the door closer to the center console), is wired to the data acquisition unit 1 outside the vehicle via an extension bracket 212, enabling real-time and stable display of the acquired video streams. Furthermore, the rearview unit 2 in this embodiment is positioned on the inside of the door, meaning the left and right rearview units 2 are arranged on the left and right sides of the vehicle body, which accommodates the driver's traditional observation habits with physical rearview mirrors, improving driving safety.

[0043] Compared to the design of placing the rearview unit 2 on both sides of the center console, placing the rearview unit 2 on the door body requires making the rearview housing 21 thinner to match the thickness of the door body. For example, please refer to... Figure 4 , Figure 4 This diagram shows a comparison of the possible heights of the rearview unit within the door base (cross-sectional comparison of door base 3). Figure 4 As shown in the example on the left, if the rearview unit 2 is made into a regular rectangle, the maximum height that can be set on the door base 3 is limited. In this embodiment of the invention, the thickness of the rearview unit 2 gradually decreases from the center region to the edge region, at least in a certain area. Specifically, as... Figure 2 and Figure 3 As shown, the rearview housing 21 has a central boss 2111 and an edge portion 2112 on its back. The edge portion 2112 forms a gradient structure, which gradually moves away from the rearview front housing from the edge of the edge portion 2112 towards the central boss 2111. In this embodiment of the present invention, the central boss 2111 of the rearview housing 21 corresponds to the thicker area in the door base 3, and the edge portion 2112 of the rearview housing 21 corresponds to the thinner area. Figure 3 The upper part of the door base 3 typically needs to have an opening to accommodate the window's operation. This opening corresponds to the lower edge of the window when fully lowered, which is generally located below the driver's shoulder. Furthermore, this lower edge is also the upper limit of the height at which the rearview unit 2 can be positioned within the door base 3. Since drivers generally need to slightly look down to observe the area below their shoulder, the rearview unit 2 needs to be positioned as high as possible within the door base 3 to obtain a better viewing angle. In this embodiment, the edge portion 2112 can adapt to the thinner area above the door base 3, allowing the rearview unit 2 to be positioned at a higher height within the door base 3, providing the driver with a better viewing angle.

[0044] Please see Figure 2 and Figure 3 The rearview housing 21 has an extension bracket 212 connected to the camera housing 11, and the extension bracket 212 has a cavity structure 2121 that passes through its end and the housing body 211. Figure 2 As shown, the extension bracket 212 of the rearview housing 21 is connected to the junction of the central boss 2111 and the gradient structure, and is located above the central boss 2111. In practical applications, the extension bracket 212 being located at the top allows the acquisition unit 1 to be positioned as high as possible, thereby increasing the driver's field of view.

[0045] Please see Figure 5 , Figure 5This diagram illustrates the structure of the rear-view housing in a first-view perspective according to an embodiment of the present invention. The end of the extension bracket 212 has a recess 2122. Specifically, the extension bracket 212 has a smooth convex curve, extending upwards and away from the rear-view housing 21 at its end near the housing. Please refer to [link / reference]. Figure 6 , Figure 6 This diagram illustrates the structure of the camera housing in a first-view perspective according to an embodiment of the present invention. The camera housing 11 has an upper protrusion 111 on the side near the extension bracket 212 that mates with the lower recess 2122. For example... Figure 5 and Figure 7 As shown, the inner sides of the upper convex portion 111 and the lower concave portion 2122 are provided with mutually cooperating locking structures (such as the second locking hole 2123 of the extension bracket 212 and the first locking hole 112 of the camera housing 11). Furthermore, since the acquisition unit 1 extends outside the vehicle, it increases the overall width of the vehicle body. However, in actual driving environments, there is a need for narrow passage. Therefore, the acquisition unit 1 needs to be able to fold inwards towards the vehicle body to reduce the overall width of the vehicle body. Therefore, the inner sides of the upper convex portion 111 and the lower concave portion 2122 can also be provided with mutually cooperating pivot structures (not shown in the figure).

[0046] In some specific embodiments, in order to better improve the internal space utilization of each rearview unit 2 and to make its edges as thin as possible, the present invention provides the following solutions:

[0047] For example, an organic light-emitting diode (OLED) screen is chosen as the rearview display 22. Compared to traditional liquid crystal displays (LCDs) and light-emitting diode (LEDs) screens, OLEDs do not require a backlight module, allowing the rearview unit 2 to be made thinner. Furthermore, as a vehicle rearview mirror, OLEDs can prevent glare from sunlight and ambient light, enabling the driver to see the video stream more clearly.

[0048] For example, the rearview housing 21 is designed as follows: Figure 2 and Figure 3 The stepped structure shown (i.e., the central boss 2111 and the edge portion 2112 with gradually varying thickness) corresponds to the PCB module 23 located inside the rear-view unit 2 being divided into a near-end region 231 and a near-center region 232. For example... Figure 9 As shown, Figure 9This diagram illustrates the distribution of components in the near-end region and near-center region of this embodiment. The near-center region 232 corresponds to the area of ​​the central boss 2111 of the rear-view housing 21, and the near-end region 231 corresponds to the area of ​​the edge portion 2112 of the rear-view housing 21. Specifically, for components disposed on the PCB module 23, if the height of the component is greater than or equal to a height threshold, the corresponding component is disposed in the near-center region 232; if the height of the component is less than the height threshold, the corresponding component is disposed in the near-end region 231. In practical applications, some components, such as capacitors or high-pin interfaces, require a large space in the thickness direction of the rearview unit 2. If these components are arbitrarily placed on the PCB module 23, it may increase the space requirements of the vehicle door. Therefore, in this embodiment of the utility model, the distribution of components in the PCB module 23 is redesigned. First, the PCB panel is divided into a near-end region 231 and a near-center region 232 according to its length direction. Then, a height threshold is set according to the accommodating space conditions in the near-end region 231. The components are divided into two groups (arranged in the near-end region 231 and the near-center region 232 respectively) using the height threshold. Finally, according to the actual circuit function requirements, the corresponding group of components is designed in the near-end region 231 and the near-center region 232 respectively.

[0049] Understandably, the specific proportions of the near-end region 231 and the near-center region 232 within the PCB module 23 depend on various factors, such as the size of the rearview screen, the accommodating space of the door base 3, and the number of components in the PCB module 23. Figure 9 The distribution ratio in the figure is only an example and should not be regarded as the only limitation on the division of the near-end region 231 and the near-center region 232.

[0050] Please see Figure 8 , Figure 8 This diagram shows a partial structural schematic of the rearview unit in an embodiment of the present invention. The thickness of the rearview housing 21 gradually increases from the edge (except for the edge connected to the central control housing) towards the center. In some specific embodiments, such as Figure 8 As shown, the minimum thickness of the rearview housing 21 ranges from 6 mm to 8 mm, corresponding to the end region of the edge portion 2112. The maximum thickness of the rearview housing 21 ranges from 24 mm to 28 mm, corresponding to the region of the central boss 2111.

[0051] In this embodiment of the invention, the layout design of the various functional components and PCB module 23 within the display device results in a structure that gradually thins from the center to the edges. This allows the maximum height of the rearview unit 2 on the door base 3 to be increased, providing the driver with a better viewing angle. Furthermore, the rearview unit 2 is connected to the acquisition unit 1 via an extension bracket 212, eliminating the need for a connection structure between the acquisition unit 1 and the rearview unit 2 inside the vehicle, thus saving interior space. Simultaneously, the physical signal cable connection between the acquisition unit 1 and the rearview unit 2 ensures the real-time performance and stability of the video stream display.

[0052] In addition to the aforementioned door display device, this embodiment of the invention also provides a vehicle equipped with the aforementioned door display device. For details regarding the specific functions and structure of the door display device, please refer to the specific embodiments described above; further details will not be repeated here.

Those skilled in the art will understand that the order of the relevant method steps should be determined by the technology itself and should not be unduly restricted by the existence of step numbers.
