[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-3 As shown, this utility model provides an automatically folding rearview mirror, including a folding arm 1 for mounting on the outside of a car and a mounting arm 2 connected to the folding arm 1. The folding arm 1 is provided with a drive module 5, and the folding arm 1 is folded or unfolded on the outside of the car through the drive module 5. The mounting arm 2 is also provided with a first mounting part 3 and a second mounting part 4, and the first mounting part 3 and the second mounting part 4 are respectively provided with a camera module one and a camera module two.

[0025] This product is mounted on the exterior of a vehicle, replacing a mechanical rearview mirror. It features impact resistance, waterproofing, and a lens that is water-repellent. In its folded or open state, it can be opened or rotated under external force. The camera itself has passed IP10 and IP69K explosion-proof and waterproof tests. The lens is coated with a waterproof film to prevent water droplets from condensing on it and affecting the viewing angle during rain.

[0026] The folding arm 1 is controlled by drive module 5 (motor 12) to fold or unfold the rearview mirror towards the vehicle body. Simultaneously, the rearview mirror integrates multiple cameras (camera module one and camera module two) to capture images of the vehicle's surroundings, providing a wider field of view and assisting the driver in observation and judgment. It is used for functions such as blind spot monitoring, lane departure warning, and surround view imaging. Different camera combinations at different angles provide image information at different distances and ranges to meet various driving assistance needs.

[0027] The folding support arm 1 includes a face cover 7, a fixing seat 14 for mounting the drive module 5, and a mounting bracket 15 for fixing to the outside of the vehicle. The face cover 7 is detachably connected to the fixing seat 14. The fixing seat 14 is provided with a cavity for accommodating the drive module 5. The fixing seat 14 is connected to the mounting bracket 15. There is a movable angle between the fixing seat 14 and the mounting bracket 15. The fixing seat 14 is also provided with a screw cover plate 13 for connecting the mounting support arm 2.

[0028] In this embodiment, the drive module 5 is installed inside the cavity of the fixed base 14, driving the fixed base 14 to rotate relative to the mounting bracket 15, thereby realizing the folding or unfolding of the folding arm 1. The cover 7 is used to protect the internal components and is connected to the fixed base 14 by the buckle 6 for easy disassembly and maintenance. The decorative cover 19 is for aesthetic purposes. During use, when the vehicle's ACC is turned on, the product automatically returns from the folded state to the working state, and the cameras turn on, allowing the in-vehicle display to see the images from the first camera 9, the second camera 10, and the third camera 18; when the ACC is turned off, the product automatically folds.

[0029] The overall advantages of this embodiment are convenience, intelligence, and improved safety when parking and passing through narrow road sections. Its cover 7 is detachable, which facilitates the replacement or maintenance of the drive module 5. The design of the movable angle between the fixed base 14 and the mounting bracket 15 ensures the movement flexibility and structural strength of the folding mechanism.

[0030] Furthermore, the mounting arm 2 includes a panel 16 and a bottom cover 20 for mounting camera module one and camera module two. The panel 16 is provided with a bracket 8 and a bracket 17 for fixing camera module one.

[0031] Bracket 1 8 and bracket 2 17 ensure that the first and second cameras 10 can be precisely installed at predetermined positions and angles, reducing the impact of vehicle vibrations on the cameras and ensuring image stability. Mounting arm 2 is used to fix camera module one and camera module two. Bracket 1 8 and bracket 2 17 on panel 16 are used to precisely fix the first and second cameras 10. Third camera 18 is located below panel 16.

[0032] Furthermore, the camera module one includes a first camera 9 and a second camera 10, the camera module two includes a third camera 18, the bracket one 8 is connected to the first camera 9, the bracket two 17 is connected to the second camera 10, and the third camera 18 is connected to the bottom cover 20.

[0033] The three cameras work together to provide images from different angles and distances, enabling comprehensive monitoring of the vehicle's surroundings. Each camera is mounted on a separate bracket, facilitating individual camera replacement or repair.

[0034] Furthermore, the horizontal viewing angle of the first camera 9 is 35.3°, the vertical viewing angle of the first camera 9 is 17°, the horizontal viewing angle of the second camera 10 is 65°, the vertical viewing angle of the second camera 10 is 57°, the horizontal viewing angle of the third camera 18 is 170°, and the vertical viewing angle of the third camera 18 is 90°.

[0035] The first camera 9 has a horizontal viewing angle of 35.3° and a vertical viewing angle of 17°. This relatively narrow angle is used for long-distance image capture, such as lane line recognition or traffic sign recognition.

[0036] The second camera 10 has a horizontal viewing angle of 65° and a vertical viewing angle of 57°. The angle is wider than that of the first camera 9, and it may be used to assist the driver in observing vehicles or pedestrians approaching from the side.

[0037] The third camera 18 has a horizontal viewing angle of 170° and a vertical viewing angle of 90°. It can cover most of the side area of ​​the vehicle for blind spot monitoring or surround view imaging.

[0038] In certain areas, multiple cameras may simultaneously capture the same target. This information redundancy can improve system reliability. For example, if the first camera 9 is obstructed, the second camera 10 can still provide some target information. Images captured by multiple cameras can be stitched and fused to generate a wider and clearer panoramic image. By analyzing the parallax between images captured by different cameras, the distance and depth information of the target can be calculated, enabling 3D environmental perception.

[0039] Furthermore, the connection between the mounting base 14 and the cover 7 is provided with multiple snap-fits 6. The bottom of the mounting base 14 is provided with a decorative cover 19, and the cover 7 is also provided with a side baffle 11 for connecting the drive module 5. The snap-fit ​​connection 6 simplifies the assembly process and facilitates the disassembly and replacement of internal components. The decorative cover 19 and the side baffle 11 provide a certain degree of protection, preventing damage to internal components. The overall structure provides a robust connection, ensuring stability under various operating conditions.

[0040] Furthermore, the drive module 5 is electrically driven and includes a motor 12. Using the motor 12 provides high control precision and fast response speed.

[0041] Furthermore, the mounting bracket 15 is connected to a mounting base and several mounting screws 21 on the mounting base. The mounting bracket 15 is fixed to the outside of the car A-pillar by the mounting screws 21, providing a firm connection and ensuring that the mounted component will not loosen during use.

[0042] Furthermore, the first camera 9, the second camera 10, and the third camera 18 are all equipped with a waterproof coating and a heating module. A special thin film adhering to the surface of the camera lens is hydrophobic, preventing moisture condensation on the lens. Heating devices integrated inside or around the camera are used to increase the overall temperature of the camera, accelerating moisture evaporation, preventing fogging or frost on the lens surface, and ensuring optimal shooting results.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
