Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an electronic rearview mirror with emergency functions. Background Technology

[0002] In the current automotive exterior rearview mirror field, although traditional physical rearview mirrors are widely used and technologically mature, they have problems such as limited field of vision and poor imaging effect in adverse weather conditions (such as heavy rain and dense fog). Electronic rearview mirrors (CMS), with the help of camera and display technology, can provide a wider and clearer field of vision and also have functions such as image enhancement. However, electronic systems are susceptible to electromagnetic interference, and once a single electronic rearview mirror system malfunctions, it will lead to a complete loss of rear view.

[0003] Existing integration solutions for physical and electronic rearview mirrors mostly suffer from complex structures, inconvenient installation, or failure to fully leverage the complementary advantages of both. Therefore, a new integration solution is urgently needed to overcome the shortcomings of existing technologies. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electronic rearview mirror with emergency functions. It has the advantages of simple structure and convenient installation, and solves the problems that most existing integrated solutions of physical and electronic rearview mirrors have complex structures, inconvenient installation, or fail to fully leverage the complementary advantages of both.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An electronic rearview mirror with emergency function includes a mirror housing, a mirror frame fixedly connected inside the mirror housing, a mirror base rotatably connected to the bottom of the mirror housing, the mirror base communicating with the mirror housing, the mirror frame including a mounting cavity and an electronic mirror area, a mirror surface embedded in the mounting cavity, a second through hole provided in the electronic mirror area, and an electronic camera fixedly connected in the second through hole.

[0006] The beneficial effects of this utility model are: 1) This electronic rearview mirror with emergency function integrates a traditional physical mirror with an electronic imaging system by setting up a mirror frame, mounting cavity, electronic mirror area, mirror surface, and electronic camera. During normal driving, the driver can mainly rely on the electronic camera to obtain a wider and clearer enhanced field of vision; when the electronic system fails due to malfunction, interference, or extreme weather, the driver can still rely on the traditional physical mirror to observe the rear situation, forming an effective emergency backup, greatly improving driving safety and reliability, and solving the problem of complete loss of rear view when a single electronic rearview mirror fails.

[0007] 2) This electronic rearview mirror with emergency functions utilizes an upper and lower mirror housing combined to form a hollow cavity to accommodate the mirror frame, base plate, and various electrical components. A wiring harness is also provided for unified management of the wiring, resulting in a rational, compact, and highly modular overall structure. This facilitates production, assembly, and subsequent maintenance, while also ensuring the stability and sealing of the internal structure. Furthermore, the turn signals are integrated into the interface between the upper and lower mirror housings, achieving a high degree of functional integration and optimizing the overall multi-functionality of the rearview mirror assembly.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the mirror housing includes an upper mirror housing and a lower mirror housing, which are fixedly connected and form a hollow cavity inside. The mirror frame is fixedly connected to the hollow cavity, and a substrate located on the rear side of the mirror frame is fixedly connected to the hollow cavity.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the split design of the upper and lower shells facilitates the installation and fixation of the internal structure, and the resulting sealed cavity provides a stable protective environment for core components such as the frame and substrate, thereby enhancing the rigidity and durability of the overall structure.

[0011] Furthermore, an adjustment motor is fixedly connected to the substrate, and a first through hole is provided in the mounting cavity. The output end of the adjustment motor passes through the first through hole and is connected to the mirror drive.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the physical mirror can be driven to adjust its angle by adjusting the motor, so that even when the driver uses the physical mirror in an emergency, he can adjust it to the best angle according to his own sitting posture and field of vision needs, thus improving the ease of use and comfort of the traditional mirror.

[0013] Furthermore, the regulating motor is electrically connected to a first wiring harness, the electronic camera is electrically connected to a second wiring harness, and a wire collection hole is provided inside the substrate. The other ends of the first and second wiring harnesses pass through the wire collection hole and the lens mount in sequence and are electrically connected to the automotive circuit.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the motor wiring harness and camera wiring harness are uniformly gathered and managed through the wiring holes inside the substrate, making the internal wiring neat and orderly, avoiding the risk of interference, wear or even short circuit caused by messy wiring harnesses, improving the reliability and service life of electrical connections, and at the same time facilitating the wiring harness to pass through the mirror mount and connect to the vehicle body circuit, simplifying the assembly process.

[0015] Furthermore, a turn signal is provided at the interface between the upper and lower mirror housings, and the turn signal is electrically connected to the vehicle's electrical circuit.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the turn signal function is integrated into the rearview mirror assembly, making full use of the product's external structure, realizing functional integration, and reducing the number of body openings and independently installed components.

Detailed Implementation

[0019] 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.

[0020] Example 1, by Figure 1-2This invention provides an electronic rearview mirror with emergency functions. The mirror includes a mirror housing 1, a mirror frame 2 fixedly connected inside the housing 1, and a mirror base 3 rotatably connected to the bottom of the housing 1. The mirror base 3 is connected to the mirror housing 1. Both the mirror housing 1 and the mirror housing 3 are made of automotive-grade engineering plastics such as ABS, PC / ABS, or aluminum alloy, manufactured through injection molding to ensure weather resistance and lightweight. The mirror base 3 is adapted to vehicle body mounting interfaces such as threaded or snap-fit ​​connections to ensure stable assembly installation. The mirror frame 2 includes a mounting cavity 21 and an electronic mirror area 22. The mirror housing 1 has a pre-reserved mounting cavity 21 for the physical lens and mounting space for the electronic camera 5, and incorporates auxiliary structures such as snap-fits and positioning posts to facilitate component positioning. The mirror housing covers the mirror, forming a accommodating space. The mirror base 3 connects to the vehicle body and supports the entire assembly. A mirror surface 4 is embedded within the mounting cavity 21. The mirror surface 4 uses a lens that conforms to automotive rearview mirror optical standards and has a suitable radius of curvature to provide basic rearward visibility. A second through-hole 6 is provided within the electronic mirror area 22, and an electronic camera 5 is fixedly connected within the second through-hole 6. The electronic camera 5 is a vehicle-grade rearview camera, possessing high temperature resistance, waterproofing, and shock resistance; its resolution is at least 720P, and its horizontal viewing angle covers 80°~120°. The camera is fixed by a metal or high-strength plastic bracket, which is connected to the substrate 7 by screws or clips. The wiring harness is treated to be waterproof and wear-resistant, and leads out from the wiring channel in the mirror housing. The mirror housing 1 includes an upper mirror housing 11 and a lower mirror housing 12, which are fixedly connected, and their interiors... The part forms a hollow cavity, and the mirror frame 2 is fixedly connected to the hollow cavity. The base plate 7 located on the rear side of the mirror frame 2 is fixedly connected to the hollow cavity. The adjustment motor 8 is fixedly connected to the base plate 7. The mounting cavity 21 has a first through hole 14. The output end of the adjustment motor 8 passes through the first through hole 14 and is driven to the mirror surface 4. The adjustment motor 8 is electrically connected to a first wire harness 9, and the electronic camera 5 is electrically connected to a second wire harness 10. The base plate 7 has a wire collection hole. The other ends of the first wire harness 9 and the second wire harness 10 pass through the wire collection hole and the mirror base 3 in sequence and are electrically connected to the automotive circuit.

[0021] In Example 2, based on Example 1, a gap is provided at the interface between the upper mirror housing 11 and the lower mirror housing 12, and a turn signal 13 is snapped into the gap. The turn signal is electrically connected to the vehicle circuit, integrating the turn signal function into the rearview mirror assembly. This makes full use of the external structure of the product, realizes functional integration, and reduces the number of openings in the vehicle body and independently installed components.

[0022] In use, the driver obtains a real-time, low-latency rear view through physical lenses. In special scenarios (such as glare from strong light, fogging of the lenses, or inclement weather), the view can be switched to the CMS electronic view, which utilizes image processing technology (such as dynamically adjusting brightness and contrast) to provide a clear image. The switching is seamlessly achieved through in-vehicle control units (such as buttons or touchscreens), without requiring physical operation of the lenses.

[0023] In summary, physical lenses cover the basic area, while electronic cameras supplement blind spots (such as the sides and rear of the vehicle), providing more comprehensive environmental perception. Furthermore, the CMS system can integrate algorithms (such as moving object detection) to enhance active safety features. When a single system fails (such as damage to the physical lenses or a CMS camera malfunction), the other system automatically maintains its function. In the event of a physical lens failure, the CMS electronic view serves as a backup, providing a field of view via a display screen.

[0024] When the electronic camera malfunctions, the physical lens reflects the light directly, ensuring basic driving safety.

[0025] This leads to improved driving safety, as the integration of the dual systems reduces the risk of complete loss of rear visibility and meets high reliability requirements.
