Description

Technical Field

[0001] This utility model relates to the field of automotive electronic components technology, and in particular to an in-vehicle display assembly and interactive device. Background Technology

[0002] With the improvement of people's living standards, cars have become an indispensable means of transportation in daily life for convenient travel. However, in actual use, rear passengers often encounter traffic accidents when opening the car door after exiting, as it is difficult to observe traffic conditions behind the vehicle. These accidents can result in collisions or scrapes with pedestrians, bicycles, or even motor vehicles, causing significant losses to life and property. Therefore, providing a safe exit environment to ensure vehicle safety is crucial. Current technology uses physical mirrors on the B-pillar to observe the side and rear of the vehicle. However, these mirrors are small and have a limited field of view, making it difficult to accurately and effectively assess the situation behind the vehicle. Increasing the size of the mirrors would result in a larger B-pillar. Furthermore, if the mirrors are integrated into the B-pillar trim, they can cause visual distortion if they match the trim's curvature, or result in poor uniformity in the B-pillar's appearance. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design an in-vehicle display assembly and an interactive device. The in-vehicle display assembly can effectively assist in accurately judging the situation on the side and rear of the vehicle, and maintain the consistency between the curved surface of the interior trim panel and the shape of the display module, thereby improving the consistency of the interior appearance.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] Design an in-vehicle display assembly, including a housing and a display module disposed on the housing. The housing includes a mounting surface, a fixing surface opposite to the mounting surface, and a slot penetrating the mounting surface and the fixing surface. The display module includes a display screen backplate and an OLED flexible display screen attached to the display screen backplate. The OLED flexible display screen is embedded in the slot. The mounting surface is curved, and the display surface of the OLED flexible display screen is adapted to the curved contour of the slot.

[0006] In this solution, a flexible OLED display replaces traditional physical lenses. The bendable nature of the OLED allows it to adapt to the curved contours of the casing, ensuring consistency in the interior and exterior surfaces and improving visual continuity. Images captured by external cameras and displayed on the OLED display eliminate viewing distortion, facilitating accurate assessment of the situation behind and to the sides of the vehicle. Furthermore, the OLED display can use color to further indicate the situation behind the vehicle. For example, a green display indicates it's safe to open the door and exit; a flashing red display indicates a vehicle or pedestrian nearby, and the door should not be opened; a yellow display indicates a vehicle or pedestrian nearby at a safe distance, requiring caution when opening the door. It's worth noting that because the OLED flexible display replaces traditional physical lenses, the installation location of the in-vehicle display assembly is not limited to the B-pillar, offering more installation options, such as the rear door panel, allowing for better integration with the vehicle's interior design.

[0007] Furthermore, the display surface of the OLED flexible display screen is not higher than the mounting surface.

[0008] In this solution, the display surface of the OLED flexible display is not higher than the mounting surface, and is as flush as possible with the mounting surface, so that the transition between the OLED flexible display and the shell is natural, which can better maintain the consistency of the interior and exterior surfaces and enhance the visual immersion.

[0009] Furthermore, the display screen back panel is provided with fixing feet on its periphery, and the fixing surface is provided with fixing protrusions corresponding to the fixing feet, and the fixing feet and the fixing protrusions are detachably connected.

[0010] In this design, since the fixing surface is curved, a fixing protrusion is designed to connect with the fixing foot. The lengths of the fixing protrusions are different, but the end faces of all the fixing protrusions are kept at the same height to facilitate connection with the fixing foot, which helps to reduce the difficulty of assembly and improve assembly efficiency.

[0011] Furthermore, at least four fixing feet are provided.

[0012] With four or more fixing feet evenly distributed around the perimeter, external impact forces, such as those from bumps and vibrations, can be effectively dispersed, avoiding localized stress concentrations caused by traditional single-point or two-point fixing, and significantly reducing the risk of display screen back panel deformation. Furthermore, with at least four fixing feet for redundancy, even if a single fixing foot fails due to wear, the remaining fixing points can still maintain basic fixing function, preventing overall fixing failure.

[0013] Furthermore, the fixing protrusion and the fixing foot are locked together by threaded fasteners.

[0014] By applying axial preload through threaded fasteners, the micro-displacement between the fixed feet and the fixed protrusion caused by vehicle vibration can be completely eliminated, thus improving vibration resistance.

[0015] A vehicle-mounted interactive device is also designed and installed on a vehicle, including the aforementioned vehicle-mounted display assembly, as well as a camera module, a radar module, and a central controller. The display module, camera module, and radar module are all connected to the central controller.

[0016] In this solution, camera and radar modules are used to detect environmental information around the vehicle. Both modules can be installed at the rear of the vehicle. The camera module can identify pedestrians and vehicles behind the vehicle and transmit the information to the central controller. When the vehicle speed is below 5 km / h, the central controller detects that the vehicle is about to stop and activates the OLED flexible display screen to show an image of the area behind the vehicle, allowing rear passengers to accurately assess the situation behind the vehicle. Additionally, based on the information detected by the camera and radar modules, the central controller can determine the distance between pedestrians and oncoming vehicles. Depending on the distance, different information is displayed on the OLED flexible display screen to alert rear passengers. For example, a green display indicates that it is safe to open the door and exit the vehicle; a flashing red display indicates that there is a vehicle or pedestrian nearby, and the door should not be opened; a yellow display indicates that there is a vehicle or pedestrian nearby, but at a safe distance, and caution is advised when opening the door. When the vehicle speed exceeds 5 km / h, the central controller recognizes that the vehicle has started moving and will turn off the OLED flexible display screen to reduce energy consumption.

[0017] Furthermore, two vehicle display assemblies are provided, and the two vehicle display assemblies are respectively installed on the B-pillar of the vehicle, and the housing is the protective plate of the B-pillar.

[0018] In this design, the B-pillar position matches the side-view height of rear passengers, facilitating direct observation when they exit the vehicle. The housing of the in-vehicle display assembly is the B-pillar trim panel, meaning the display module is directly fixed to the B-pillar trim panel, simplifying the installation process.

[0019] Furthermore, two vehicle display assemblies are provided, and the two vehicle display assemblies are respectively installed on the rear doors of the vehicle, and the housing is the door panel.

[0020] In this solution, the in-vehicle display assembly is installed on the rear doors of the vehicle, such as the door armrest. The OLED flexible display screen can integrate other operating functions for easy operation by rear passengers.

[0021] Furthermore, one vehicle display assembly is provided, which is located at one end of the vehicle armrest box facing the rear seats, and the housing is the outer shell of the armrest box.

[0022] In this solution, the in-vehicle display assembly is located at the end of the vehicle's armrest box facing the rear seats. The OLED flexible display screen can integrate other operating functions, making it convenient for rear passengers to operate and use.

[0023] Furthermore, it also includes an audio module, which is connected to the central controller.

[0024] In this solution, the in-vehicle interactive device also includes an audio module, which plays voice prompts to proactively remind rear passengers.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] In this solution, a flexible OLED display replaces traditional physical lenses. The bendable nature of the OLED allows it to adapt to the curved contours of the casing, ensuring consistency in the interior and exterior surfaces and improving visual continuity. Images captured by external cameras and displayed on the OLED display eliminate viewing distortion, facilitating accurate assessment of the situation behind and to the sides of the vehicle. Furthermore, the OLED display can use color to further indicate the situation behind the vehicle. For example, a green display indicates it's safe to open the door and exit; a flashing red display indicates a vehicle or pedestrian nearby, and the door should not be opened; a yellow display indicates a vehicle or pedestrian nearby at a safe distance, requiring caution when opening the door. It's worth noting that because the OLED flexible display replaces traditional physical lenses, the installation location of the in-vehicle display assembly is not limited to the B-pillar, offering more installation options, such as the rear door panel, allowing for better integration with the vehicle's interior design.

[0032] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Example 1:

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides an in-vehicle display assembly 10, including a housing 11 and a display module 12 disposed on the housing 11. The housing 11 includes a mounting surface 111, a fixing surface 112 facing away from the mounting surface 111, and a slot 113 connecting the mounting surface 111 and the fixing surface 112. The display module 12 includes a display screen backplate 122 and an OLED flexible display screen 121 attached to the display screen backplate 122. The OLED flexible display screen 121 is embedded in the slot 113. The mounting surface 111 is curved, and the display surface of the OLED flexible display screen 121 is adapted to the curved contour of the slot 113. The display surface of the OLED flexible display screen 121 is not higher than the mounting surface 111, and as far as possible, the display surface of the OLED flexible display screen 121 is flush with the mounting surface 111. It should be noted that the shape of the OLED flexible display screen 121 is not limited and can be circular, elliptical, rectangular, etc. In this embodiment, the OLED flexible display screen 121 is rectangular, and it is bent with a certain curvature to adapt to the curved surface of the mounting surface 111.

[0034] Additionally, the OLED flexible display 121 is fully bonded to the display back panel 122 using an SCF film and VHB double-sided adhesive. Therefore, the surface of the display back panel 122 that is bonded to the OLED flexible display 121 is also curved. The display module 12 also includes a motherboard, which is fixed to the side of the display back panel 122 opposite to the OLED flexible display 121. A series of holes are formed on the display back panel 122, and the OLED flexible display 121 is electrically connected to the motherboard via a ribbon cable.

[0035] like Figure 2As shown, the display screen back panel 122 has fixing feet 1221 around its periphery, and the fixing surface 112 has fixing protrusions 114 corresponding to the fixing feet 1221. The fixing protrusions 114 are located around the slot 113, and the fixing feet 1221 and fixing protrusions 114 are detachably connected. Since the fixing surface 112 is curved, the fixing protrusions 114 are designed to connect with the fixing feet 1221. The lengths of the fixing protrusions 114 vary, but the end faces of all fixing protrusions 114 are kept at the same height to facilitate connection with the fixing feet 1221, thereby reducing assembly difficulty and improving assembly efficiency. The detachable connection between the fixing feet 1221 and fixing protrusions 114 can be achieved using a snap-fit ​​connection or a threaded fastener 115. In this embodiment, the fixed protrusion 114 and the fixed foot 1221 are locked together by a threaded fastener 115. Specifically, the fixed protrusion 114 has a threaded hole, and the fixed foot 1221 has a through hole. The threaded fastener 115 passes through the through hole and is tightened into the threaded hole. By applying axial preload through the threaded fastener, the micro-displacement between the fixed foot 1221 and the fixed protrusion 114 caused by vehicle vibration can be completely eliminated, thus improving vibration resistance.

[0036] In addition, at least four fixing feet 1221 are provided. The even distribution of four or more fixing feet 1221 around the perimeter effectively disperses external impact forces, such as those from bumps and vibrations, avoiding localized stress concentrations caused by traditional single-point or two-point fixing, and significantly reducing the risk of deformation of the display screen back panel 122. Furthermore, the presence of at least four fixing feet 1221 provides redundancy; even if a single fixing foot 1221 fails due to wear, the remaining fixing points can still maintain basic fixing function, preventing overall fixing failure.

[0037] In this embodiment, a flexible OLED display 121 replaces the traditional physical lens. Utilizing the bendable nature of the OLED display 121, it adapts to the curved contour of the slot 113 in the housing 11. The display surface of the OLED display 121 is flush with the mounting surface, allowing for a natural transition between the OLED display 121 and the housing 11. This better maintains the consistency of the interior and exterior surfaces, enhances visual immersion, and improves visual continuity. Images captured by an external camera and displayed on the OLED display 121 eliminate viewing distortion, facilitating accurate assessment of the situation behind and to the side of the vehicle. Furthermore, the OLED display 121 can also use color to further indicate the situation behind the vehicle. For example, if the OLED display 121 shows green, it indicates that it is safe to open the door and get out; if it flashes red, it indicates that there are vehicles or pedestrians nearby, and the door should not be opened; if it shows yellow, it indicates that there are vehicles or pedestrians nearby, but at a safe distance, and caution is advised when opening the door. It should be noted that, since the OLED flexible display 121 replaces the traditional physical lens, the installation position of the vehicle display assembly 10 is not limited to the B-pillar of the vehicle, and there are more installation options available, such as the rear door panel, which can be better integrated with the vehicle interior design. Example 2:

[0038] like Figure 3 As shown, this embodiment provides an in-vehicle interactive device installed on a vehicle, including the aforementioned in-vehicle display assembly 10, as well as a camera module 20, a radar module 30, and a central controller 40. The display module 12, camera module 20, and radar module 30 are all connected to the central controller 40 via a CAN bus network.

[0039] In this embodiment, two vehicle display assemblies 10 are provided, and the two vehicle display assemblies 10 are respectively installed on the B-pillar of the vehicle. The housing 11 is a protective plate for the B-pillar, as detailed below. Figure 4 As shown, the B-pillar position matches the side-view height of rear passengers, facilitating direct observation when they exit the vehicle. The housing 11 of the vehicle display assembly 10 serves as a B-pillar guard plate, meaning the display module 12 is directly fixed to the B-pillar guard plate. The guard plate is mounted on the B-pillar support frame, simplifying the installation process. In other possible embodiments, the housing 11 can also be fixed to the B-pillar guard plate using snap-fit ​​or threaded fasteners, meaning the entire vehicle display assembly 10 is fixed to the B-pillar guard plate using snap-fit ​​or threaded fasteners.

[0040] The camera module 20 and radar module 30 are used to detect environmental information around the vehicle. Both the camera module 20 and radar module 30 can be installed at the rear of the vehicle. The camera module 20 can identify pedestrians and vehicles behind the vehicle and transmit the information to the central controller 40. When the vehicle speed is below 5 km / h, the central controller 40 recognizes that the vehicle is about to stop and turns on the OLED flexible display screen 121 to display the image behind the vehicle so that the rear passengers can accurately judge the situation on the side and rear of the vehicle. In addition, based on the information detected by the camera module 20 and radar module 30, the central controller 40 can determine the distance between pedestrians and oncoming vehicles behind the vehicle. According to the distance between pedestrians and oncoming vehicles, different screen information is displayed on the OLED flexible display screen 121 to remind the rear passengers. For example, if the OLED flexible display 121 shows green, it means the car door can be opened normally to get out; if the OLED flexible display 121 flashes red, it means there are vehicles or pedestrians nearby, and the door cannot be opened; if the OLED flexible display 121 shows yellow, it means there are vehicles or pedestrians nearby, but at a safe distance, and caution is needed when opening the door to get out. When the vehicle speed exceeds 5 km / h, the central controller 40 recognizes that the vehicle has started moving and will turn off the display on the OLED flexible display 121 to reduce energy consumption.

[0041] In other possible embodiments, the in-vehicle interactive device may also include an audio module 50, which is connected to the central controller 40 via a CAN bus network. When rear passengers exit the vehicle, the audio module 50 plays a voice prompt to actively remind them.

[0042] In other possible embodiments, two vehicle display assemblies 10 are provided, each mounted on a rear door of the vehicle, with the housing 11 serving as a door panel. The vehicle display assemblies 10 are mounted on the rear doors, for example, at the door armrest. The OLED flexible display screen 121 can integrate other operating functions, such as seat adjustment and lighting adjustment, for convenient operation by rear passengers.

[0043] In other possible embodiments, a single in-vehicle display assembly 10 is provided, capable of displaying information from the left and right rear sides of the vehicle in a split-screen manner. The in-vehicle display assembly 10 is located at the end of the vehicle's armrest box facing the rear seats, and the housing 11 is the outer shell of the armrest box. The in-vehicle display assembly 10 is located at the end of the vehicle's armrest box facing the rear seats, and the OLED flexible display screen 121 can integrate other operating functions, such as air conditioning adjustment and armrest box adjustment, for convenient operation and use by rear passengers.
