[0031] like Figure 1-7 As shown, a preferred embodiment of the present invention provides a fault replacement structure for an electronic exterior rearview mirror, comprising: a camera module and an emergency mirror, both of which are disposed within a housing 1;

[0032] The emergency mirror includes a first emergency mirror 2 and a second emergency mirror 3; the first emergency mirror 2 includes a first emergency lens 21 and a first emergency mirror frame 22; the first emergency lens 21 is disposed inside the first emergency mirror frame 22, and an adhesive layer 4 and a protective layer 5 are disposed between the first emergency lens 21 and the first emergency mirror frame 22; a fixing buckle 23 is provided inside the outer shell 1, and the first emergency mirror 2 is fixed inside the outer shell 1 by the fixing buckle 23.

[0033] The second emergency mirror 3 includes a second emergency lens 31 and a second emergency mirror frame 32; the second emergency lens 31 is disposed inside the second emergency mirror frame 32, and an adhesive layer 4 and a protective layer 5 are disposed between the second emergency lens 31 and the second emergency mirror frame 32; the outer shell 1 is provided with an emergency mirror slide 33 that slides in cooperation with the second emergency mirror 3; the outer shell 1 is also provided with a fixed cylinder 34 and a movable cylinder 35, the extension end of the fixed cylinder 34 controls the movable cylinder 35 to slide on the cylinder slide 36, the extension end of the movable cylinder 35 is connected to the second emergency mirror 3 through a hinge 37, and the second emergency mirror 3 is controlled to slide on the emergency mirror slide by the cooperation of the fixed cylinder 34 and the movable cylinder 35.

[0034] Specifically, both the camera module and the emergency mirror are installed inside the housing 1. The emergency mirror consists of a first emergency mirror 2 and a second emergency mirror 3. The first emergency mirror 2 includes a first emergency lens 21 and a first emergency mirror frame 22. The first emergency lens 21 is embedded inside the first emergency mirror frame 22, and an adhesive layer 4 and a protective layer 5 are sequentially arranged between them, making the connection between the first emergency lens 21 and the first emergency mirror frame 22 more stable. At the same time, the protective layer 5 can improve the impact resistance and durability of the lens. To ensure that the first emergency mirror 2 can be stably fixed inside the housing 1, a fixing buckle is provided inside the housing 1, and the first emergency mirror 2 is locked inside the housing 1 by the fixing buckle 23. The second emergency mirror 3 includes a second emergency lens 31 and a second emergency mirror frame 32. The second emergency lens 31 is also disposed inside the second emergency mirror frame 32, with an adhesive layer 4 and a protective layer 5 sequentially arranged between them to enhance the reliable connection and damage resistance between the lens and the frame. To realize the movable switching of the second emergency mirror 3, an emergency mirror slide 33 is provided inside the housing 1 to cooperate with it. The housing 1 also includes a fixed cylinder 34 and a movable cylinder 35. The telescopic end of the fixed cylinder 34 controls the movable cylinder 35 to slide along the cylinder slide rail 36. The telescopic end of the movable cylinder 35 is connected to the second emergency mirror 3 via a hinge 37. Under the coordinated action of the fixed cylinder 34 and the movable cylinder 35, the second emergency mirror 3 can be driven to smoothly slide and switch within the emergency mirror slide rail 33. When the electronic rearview mirror camera module fails, the second emergency mirror 3 can quickly move to a preset position, providing the driver with a reliable rear view.

[0035] Understandably, by installing a first emergency mirror 2 and a second emergency mirror 3 within the housing 1, the emergency mirrors can be quickly put into use when the camera module of the electronic rearview mirror malfunctions, providing the driver with basic rear visibility, avoiding blind spots during driving, and effectively ensuring driving safety. The first emergency mirror 2 is fixed inside the housing 1 with a fastener, and can be used directly as a backup observation device when the camera module fails; the second emergency mirror 3 achieves smooth sliding switching through a slide rail and cylinder drive, and can be quickly switched to the usable position in an emergency, ensuring sufficient visibility and improving the timeliness of emergency functions. Both the first emergency mirror 21 and the second emergency mirror 31 have an adhesive layer 4 and a protective layer 5 between them and the mirror frame. This multi-layer structure not only improves the bonding strength between the mirror and the mirror frame, but also enhances the impact resistance and protective performance of the mirror.

[0036] In some embodiments of this application, the camera module includes a rearview mirror camera 6 and a protective shell 7. The protective shell 7 has a hole in the middle that cooperates with the rearview mirror camera 6 for a sealed connection, and the protective shell 7 is sealed to the outer shell 1 on all four sides.

[0037] Specifically, the rearview mirror camera 6 is used to collect image information from behind and to the sides of the vehicle and transmit the image signals to the in-vehicle display unit to provide the driver with a real-time rear view image. To ensure that the rearview mirror camera 6 is protected from dust, moisture, and external impacts during vehicle operation, the camera module is designed with a dedicated protective shell 7. The protective shell 7 has a hole in the center that matches the rearview mirror camera 6. This hole and the rearview mirror camera 6 form a sealed connection, preventing rainwater, dust, or other foreign objects from entering the camera's interior, while ensuring that the camera's imaging angle is not affected. The protective shell 7 is sealed to the outer shell 1 on all four sides using a waterproof sealing strip or adhesive sealing method to achieve an overall seal, thereby further improving the protective performance of the camera module.

[0038] In some embodiments of this application, the connection structure between the first emergency lens 21 and the first emergency lens frame 22, and between the second emergency lens 31 and the second emergency lens frame 32, is an adhesive layer 4, a protective layer 5, and an adhesive layer 4 in sequence.

[0039] Specifically, the connection structures between the first emergency lens 21 and the first emergency lens frame 22, and between the second emergency lens 31 and the second emergency lens frame 32, both adopt a multi-layer combination form, consisting of an adhesive layer 4, a protective layer 5, and another adhesive layer 4. The purpose of this structural design is to simultaneously meet the requirements of lens fixation reliability and protective performance.

[0040] In some embodiments of this application, both the first emergency mirror frame 22 and the second emergency mirror frame 32 are provided with fixed ends.

[0041] Specifically, both the first emergency mirror frame 22 and the second emergency mirror frame 32 are provided with fixed ends. These fixed ends reliably secure the upper and lower ends of the emergency mirror lens within the frame, ensuring the lens's stability. During vehicle operation, road vibrations, braking, or steering may generate impact forces. If the lens is not adequately secured, it is prone to shaking or shifting, affecting the driver's visibility and potentially causing the lens to detach. By providing fixed ends to the mirror frames, both the upper and lower ends are constrained, effectively preventing the lens from shaking or slipping under external forces.

[0042] In some embodiments of this application, the fixing buckle 23 is divided into an upper fixing buckle and a lower fixing buckle, which are located at the upper and lower ends of the first emergency mirror 2, respectively.

[0043] Specifically, the fixing buckle 23 consists of an upper fixing buckle and a lower fixing buckle, located at the upper and lower ends of the first emergency mirror 2, respectively, to securely fix the first emergency mirror 2 inside the housing 1. The upper fixing buckle, located at the upper end of the first emergency mirror 2, engages with the upper end of the first emergency mirror frame 22 to restrain the lens towards the top of the housing 1, preventing displacement of the upper end of the lens during vibration or impact. The lower fixing buckle, located at the lower end of the first emergency mirror 2, engages with the lower end of the mirror frame to restrain the lower end of the lens, preventing it from wobbling or slipping. The dual restraint of the upper and lower fixing buckles ensures that the first emergency mirror 2 maintains a stable position and correct reflection angle during vehicle operation, even when encountering bumps, sudden braking, or steering.

[0044] In some embodiments of this application, the emergency mirror slide 33 includes a hidden slide section 331 and a usable slide section 332; the hidden slide section 331 is in the shape of a straight line, and the usable slide section 332 is in the shape of a trapezoid.

[0045] Specifically, the emergency mirror slide 33 includes a concealed slide section 331 and a usable slide section 332 to achieve stable storage and controllable sliding of the second emergency mirror 3 within the housing 1. The concealed slide section 331 is linear and located in a hidden position inside the housing 1. It is used to store the second emergency mirror 3 in a concealed state when the electronic rearview mirror is working normally, so as not to affect the imaging and overall appearance of the camera module 6. The usable slide section 332 is trapezoidal and connected to the concealed slide section 331. When the electronic rearview mirror camera module fails or needs to be used in an emergency, the second emergency mirror 3 can slide out along the usable slide section 332 to the predetermined observation position. The trapezoidal structure ensures that the lens gradually unfolds during the sliding process, while adjusting the lens's elevation angle and position to provide the best reflected field of view. By combining the design of the hidden slide section 331 and the usable slide section 332, the second emergency mirror 3 can be stored and hidden when not in use and can be smoothly slid out when in an emergency. This ensures that the emergency mirror is spatially coordinated with the housing and other components when in use, while also improving the reliability and ease of operation of the electronic exterior rearview mirror system.

[0046] In some embodiments of this application, the emergency mirror slide 33 is divided into an upper emergency mirror slide and a lower emergency mirror slide, which are located at the upper and lower ends of the second emergency mirror 3, respectively.

[0047] Specifically, the emergency mirror slide 33 is further subdivided into an upper emergency mirror slide and a lower emergency mirror slide, located at the upper and lower ends of the second emergency mirror 3, respectively. The upper emergency mirror slide, located at the upper end of the second emergency mirror 3, cooperates with the telescopic end of the moving cylinder 35 to guide the upper end of the mirror to move smoothly along a predetermined trajectory during sliding, preventing tilting or deviation. The lower emergency mirror slide, located at the lower end of the second emergency mirror 3, constrains the movement of the lower end of the mirror, ensuring stability and synchronization with the upper end during sliding, preventing shaking or jamming. Through the dual-track constraint design of the upper and lower slides, the second emergency mirror 3 maintains a consistent horizontal and elevation angle of the mirror while sliding along the slide, ensuring the driver has a clear and accurate rear view in emergency situations. The cooperation of the upper and lower slides also disperses external forces, enhancing the stability of the mirror under vibration or collision conditions.

[0048] In some embodiments of this application, the emergency mirror slide 33 is provided with a slide end point 333.

[0049] Specifically, the emergency mirror slide 33 is provided with a slide end point 333, which is used to limit the final position of the second emergency mirror 3 during the sliding process. When the electronic exterior rearview mirror camera module fails or the driver needs to activate the emergency mirror, the second emergency mirror 3 slides along the emergency mirror slide 33 to the use position. The slide end point 333 can accurately limit the sliding distance of the lens to prevent the lens from exceeding the predetermined position or impacting the internal structure of the housing.

[0050] In some embodiments of this application, the outer casing 1 is further provided with a ramp end 11.

[0051] Specifically, the outer casing 1 is also provided with a ramp end 11 to guide rainwater or other liquids to flow out smoothly and prevent moisture from accumulating inside the casing.

[0052] In some embodiments of this application, a rearview mirror handle 8 is also included, which is connected to the vehicle.

[0053] Specifically, the electronic exterior rearview mirror also includes a mirror handle 8, used to securely connect and install the entire exterior rearview mirror assembly to the vehicle body. The mirror handle 8 is fixedly connected to the housing 1 and installed on the vehicle's door or side bracket using bolts, clips, or other reliable fixing methods, ensuring the entire exterior rearview mirror remains stable and reliable during vehicle operation, preventing loosening due to vibration, wind resistance, or impact. The mirror handle 8 can also provide appropriate adjustment interfaces or angle adjustment functions, allowing the installed exterior rearview mirror to be fine-tuned according to the vehicle structure and driver's viewing angle, ensuring the camera module and emergency mirror provide the optimal observation angle in both normal operation and emergency situations.

[0054] The working process of this utility model is as follows: When the rearview mirror camera 6 is working normally, the second emergency mirror 3 is in a hidden state, located behind the first emergency mirror 2, and does not affect the imaging of the rearview mirror camera 6. When the rearview mirror camera 6 fails or malfunctions, the first emergency mirror 2 can be used for emergency observation, and the second emergency mirror 3 can be activated to complete the observation area. The fixed cylinder 34 extends first, fixing the moving cylinder 35 and the second emergency mirror 3 to the initial position along the emergency mirror slide 33, providing support and constraint for subsequent sliding actions. The moving cylinder 35 is connected to the second emergency mirror 3 through the telescopic end and the hinge 37. Under the support of the fixed cylinder 34, it slides along the emergency mirror slide 33, pushing the second emergency mirror 3 to the predetermined position. The moving cylinder 35 pushes the second emergency mirror 3 forward, adjusting the lens angle to splice and close with the first emergency mirror 2, so that the driver can obtain a clear rear view. After the second emergency mirror 3 is in place, the fixed cylinder 34 and the moving cylinder 35 maintain a stable position. The emergency mirror can remain stable under vehicle vibration or road condition changes, ensuring a clear and reliable field of vision. When the rearview mirror camera 6 returns to normal or the driver finishes emergency use, the movable cylinder 35 slides in the opposite direction along the emergency mirror slide rail 33, while adjusting the angle of the second emergency mirror 3 and pulling it back; then the fixed cylinder 34 retracts, and the second emergency mirror 3 is retracted along the emergency mirror slide rail 33, ensuring that the second emergency mirror 3 is completely stored inside the housing 1, restoring the normal working state of the electronic exterior rearview mirror.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
