Description

Technical Field

[0001] This utility model relates to the field of motor vehicle rearview mirror technology, and in particular to a vehicle-mounted electronic rearview mirror. Background Technology

[0002] Compared to traditional physical rearview mirrors, in-vehicle electronic rearview mirrors (Camera Monitor System, CMS) have advantages such as a wider field of view, lower drag coefficient, better night vision, and less impact from inclement weather, and have been well received by many drivers.

[0003] Currently, the mainstream automotive electronic rearview mirrors on the market are divided into two types in terms of overall architecture: one is a 1-to-1 system architecture, which sets up corresponding SOC systems, MCUs, and CAN transceivers in the left and right rearview displays to receive and process the image data transmitted from the corresponding cameras. Although this architecture does not require a separate controller component, it still requires two of the other components, resulting in high costs. The other is a 1-to-2 system architecture, which sets up a separate controller component. The image data captured by the left and right cameras is first transmitted to the controller component, processed, and then transmitted to the corresponding left and right rearview displays for display. Although this architecture only requires a SOC system, MCU, and CAN transceiver in the controller component, the controller component is set up independently, which also results in higher costs. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a vehicle-mounted electronic rearview mirror that can effectively reduce costs.

[0006] Furthermore, the ECU module also includes an MCU chip and a CAN transceiver. The MCU chip is connected to the SOC chip and the CAN transceiver to connect to the vehicle's CAN bus via the CAN transceiver to obtain corresponding control commands and control the SOC chip to process the image data transmitted by the first camera and the second camera.

[0007] Furthermore, the first camera, the second camera, the first display screen, and the second display screen all include a power supply unit for supplying power to each power-consuming component.

[0008] Furthermore, the vehicle-mounted electronic rearview mirror also includes a heat dissipation module disposed in the first display screen.

[0009] After adopting the above technical solution, the present utility model embodiment has at least the following beneficial effects: The vehicle electronic rearview mirror provided by the present utility model embodiment integrates an ECU module inside the first display screen, and uses the original first deserializer of the first display screen to simultaneously receive image data transmitted by the first camera and the second camera respectively. The SOC chip of the ECU module processes the image data in a unified manner and then distributes it to the first display unit and the second display unit for display. The number of components used is relatively small, which effectively reduces hardware costs and improves the cost performance of the product. Attached Figure Description

[0010] Figure 1This is a circuit block diagram of an optional embodiment of the vehicle-mounted electronic rearview mirror of this utility model. Detailed Implementation

[0011] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the following illustrative embodiments and descriptions are only used to explain the present utility model and are not intended to limit the present utility model. Moreover, the embodiments and features in the embodiments of the present application can be combined with each other unless otherwise specified.

[0012] like Figure 1 As shown, an optional embodiment of this utility model provides a vehicle electronic rearview mirror, including: a first camera 1, a second camera 2, a first display screen 3, a second display screen 4, and an ECU module 5.

[0013] The first camera 1 is equipped with a first serializer 10, the second camera 2 is equipped with a second serializer 20, the first display screen 3 includes a first display unit 30 and a first deserializer 32, the second display screen 4 includes a second display unit 40 and a second deserializer 42 connected to the second display unit 40, the first deserializer 32 is connected to the first serializer 10 and the second serializer 20 respectively to receive the image data captured and transmitted by the first camera 1 and the second camera 2, the ECU module 5 is integrated inside the first display screen 3, the ECU module 5 includes: a SOC chip 50 and a third serializer 52, wherein the SOC chip 50 is connected to the first deserializer 32, the first display unit 30 and the third serializer 52 respectively, the third serializer 52 is connected to the second deserializer 42, the SOC chip 50 processes the image data transmitted by the first camera 1 and the second camera 2 and then transmits the image captured by the first camera 1 to the first display unit 30 for display and transmits the image captured by the second camera 2 to the second display unit 40 for display in sequence via the third serializer 52 and the second deserializer 42.

[0014] This embodiment integrates an ECU module 5 inside the first display screen 3. With the help of the first deserializer 32 of the first display screen 3, it can simultaneously receive image data transmitted by the first camera 1 and the second camera 2 respectively. The SOC chip 50 of the ECU module 5 processes the image data and then distributes it to the first display unit 30 and the second display unit 40 respectively for display. The number of components used is relatively small, which effectively reduces hardware costs and improves the cost performance of the product.

[0015] In another optional embodiment of this utility model, such as Figure 1As shown, the ECU module 5 further includes an MCU chip 54 and a CAN transceiver 56. The MCU chip 54 is connected to the SOC chip 50 and the CAN transceiver 56 to connect to the vehicle's CAN bus 6 via the CAN transceiver 56 to obtain corresponding control commands and control the SOC chip 50 to process the image data transmitted by the first camera 1 and the second camera 2. This embodiment, by further adding the MCU chip 54 and the CAN transceiver 56, can better respond to the control commands issued by the user through the vehicle system and perform further operational control on the image display.

[0016] In yet another optional embodiment of this utility model, such as Figure 1 As shown, the first camera 1, the second camera 2, the first display screen 3, and the second display screen 4 each include a power supply unit 7 for supplying power to each power-consuming component. This embodiment facilitates power supply to the respective internal power-consuming components by providing power supply units 7 for the first camera 1, the second camera 2, the first display screen 3, and the second display screen 4.

[0017] In another optional embodiment of this utility model, such as Figure 1 As shown, the vehicle-mounted electronic rearview mirror also includes a heat dissipation module 8 disposed in the first display screen 3. Since the ECU module 5 is integrated into the first display screen 3, the overall heat generated by the first display screen 3 and the ECU module 5 during operation is greater than that of the second display screen 4. Therefore, this embodiment further incorporates the heat dissipation module 8 within the first display screen 3 to effectively dissipate heat and control the operating temperature of the first display screen 3 and the ECU module 5 within a suitable range, preventing overheating. In specific implementations, the heat dissipation module 8 can be various common heat dissipation components such as heat sink fins, cooling fans, and heat pipes, and can be flexibly selected based on the actual heat dissipation requirements.
