[0001] The utility model relates to the technical field of automotive rearview mirrors, and particularly to an automotive rearview mirror with automatic anti-fogging function. Background Technique

[0002] During the process of driving a vehicle, the clarity of the rearview mirror is crucial for the driver's vision and safety. However, in rainy days, foggy days or environments with large temperature differences, water mist is likely to form on the surface of the rearview mirror, seriously affecting the driver's line of sight and increasing potential safety hazards during driving. The traditional method for removing water mist is mainly to use heating wires to heat the lens for defogging, but this method has many deficiencies.

[0003] Although using heating wires to remove fog can solve the problem to a certain extent, the coverage area that the heating wires can cover is limited, and they can only work on a small part of the lens they cover. However, during the driving process, any uncertain factor may lead to a traffic accident. Therefore, an automotive rearview mirror with automatic anti-fogging function is needed to remove water mist on the mirror surface more comprehensively.

[0004] In view of this, an automotive rearview mirror with automatic anti-fogging function is provided to overcome the above-mentioned defects. Content of the Utility Model

An S-shaped circulating air duct formed by connecting a plurality of straight-section concave-shaped pipes in sequence is installed on the inner wall of the lens. The other end of the connecting pipe is connected to the circulating air duct. The concave surface of the circulating air duct is close to the heating module.

[0007] Further, one end of the circulating air duct is fixedly connected with an air outlet pipe.

[0008] Further, a rain shield is integrally formed at the front end of the rearview mirror housing. A "U"-shaped exhaust hole with two openings is formed at the inner edge position of the rearview mirror housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Refer to Figures 1-4, An automotive rearview mirror with automatic anti-fog function, comprising a rearview mirror housing 1 and a lens 3. A heating module 12 is provided on the back of the lens 3. A through groove 14 is formed inside the rearview mirror housing 1. A funnel-shaped second protective cover 8 is fixedly installed inside the through groove 14. One end of the second protective cover 8 is fixedly connected to a rotary connecting pipe 9. An S-shaped circulating air duct 11 formed by connecting multiple straight-section concave-shaped pipes in sequence is installed on the inner wall of the lens 3. The other end of the rotary connecting pipe 9 is connected to the circulating air duct 11. The concave surface of the circulating air duct 11 is close to the heating module 12.

[0023] By setting that the circulating air duct 11 is formed by connecting multiple straight-section concave-shaped pipes in sequence and the concave surface of the circulating air duct 11 is close to the heating module 12, when the air enters the inside of the circulating air duct 11 and is above the heating module 12, it can be heated by the circulating air duct 11 to form hot air and move inside the circulating air duct 11. And since the whole circulating air duct 11 is S-shaped, the air will be heated by the heating module 12 multiple times. During the process of the hot air moving in the circulating air duct 11, the temperature of the surface of the lens 3 will be increased. When the temperature of the lens 3 is higher than the dew point temperature in the surrounding air, the water mist on the lens surface will start to change.

[0024] Furthermore, one end of the circulating air duct 11 is fixedly connected to an air outlet pipe 13. A rain shield 10 is integrally formed at the front end of the rearview mirror housing 1. An "U"-shaped exhaust hole 4 with two openings is formed at the inner edge position of the rearview mirror housing 1. The two openings of the exhaust hole 4 are respectively located on the inner wall of the rearview mirror housing 1 and the outer wall of the rain shield 10. One side of the air outlet pipe 13 is attached to the inner wall of the rearview mirror housing 1. The opening of the exhaust hole 4 located on the inner wall of the rearview mirror housing 1 is within the fitting range of the air outlet pipe 13 and the inner wall of the rearview mirror housing 1.

[0025] By setting the air outlet pipe 13 and the "U"-shaped exhaust hole 4 with two openings, and setting that one side of the air outlet pipe 13 is attached to the inner wall of the rearview mirror housing 1 and the opening of the exhaust hole 4 located on the inner wall of the rearview mirror housing 1 is within the fitting range of the air outlet pipe 13 and the inner wall of the rearview mirror housing 1, the hot air flowing out of the circulating air duct 11 can be introduced into the exhaust hole 4 through the air outlet pipe 13 and then directly conveyed to the surface of the lens 3 through the openings of the exhaust hole 4. So that the water droplets attached to the surface of the lens 3 in the rain state can be blown by the hot air and slide off the surface of the lens 3 more quickly, avoiding the water droplets that cannot be removed by the heating module 12 from affecting the driver's line of sight and increasing the driving safety of the user.

[0026] Even further, the specific position of the through groove 14 is at the lower right corner of the rear outer wall of the rearview mirror housing 1. An air inlet pipe 6 is fixedly installed at the rear end inside the through groove 14. An air inlet 5 in the shape of a funnel is installed at the rear end of the air inlet pipe 6. A funnel-shaped first protective cover 7 is fixedly installed at the front end of the air inlet pipe 6.

[0027] By setting the specific position of the through groove 14 at the lower right corner of the outer rear wall of the rearview mirror housing 1, the presence of the through groove 14 and related components will not overly affect the installation of other components inside the device.

[0028] By installing a funnel-shaped air inlet 5 at the rear end of the air inlet pipe 6, more air can enter the interior of the air inlet pipe 6 during the driving of the vehicle. By fixedly installing a funnel-shaped first protective cover 7 at the front end of the air inlet pipe 6 and arranging a second protective cover 8 which is also funnel-shaped inside the through groove 14, the components on the other side of the adapter pipe 9 in the device will not be easily affected by rainwater. During the driving of the vehicle, rainwater may enter the interior of the air inlet pipe 6. At this time, the funnel-shaped first protective cover 7 will prevent the rainwater from easily entering the through groove 14, and the second protective cover 8 inside the through groove 14 can further prevent the rainwater from entering the other side of the adapter pipe 9.

[0029] In addition, a mounting seat 2 is integrally formed at the edge position of the rearview mirror housing 1.

[0030] During specific implementation, under normal conditions, the heating and defogging function of an ordinary rearview mirror can only be achieved at the position where the heating wire is installed, and there will still be water mist at other positions, and slight impacts during the driving of the vehicle may lead to traffic accidents.

[0031] In this utility model, during the driving of the vehicle, air enters the interior of the device from the air inlet 5, passes through the air inlet pipe 6, the first protective cover 7, and the second protective cover 8, and then enters the circulation air duct 11 through the adapter pipe 9. The concave surface of the circulation air duct 11 is close to the heating module 12. Therefore, when the air is above the heating module 12 after entering the interior of the circulation air duct 11, it can be heated by the circulation air duct 11 to form hot air and move inside the circulation air duct 11. And since the circulation air duct 11 is overall in an S shape, the air will be heated by the heating module 12 multiple times. During the movement of the hot air inside the circulation air duct 11, the temperature of the place on the surface of the lens 3 where the heating module 12 is not distributed will be increased, so that most of the surface of the lens 3 can be heated, and most of the water mist on the surface of the lens 3 can be removed.

[0032] At the same time, after the air is circulated inside the circulation air duct 11, it will be discharged from the exhaust air duct 13 through the exhaust hole 4 and directly blow on the surface of the lens 3, and the water droplets that are not easily atomized on the surface of the lens 3 can be blown away by the exhaust hole 4, further increasing the effect of the device for removing water mist.

[0033] By setting the circulation air duct 11, the device can increase the range and effect of overall water mist removal without adding too many other components driven by energy, which can not only improve driving safety but also enhance the overall user experience.

[0034] Working principle: Under normal conditions, the heating and anti-fog function of an ordinary rearview mirror can only be achieved at the position where the heating wire is installed, and there will still be water mist in other positions, and even a slight impact during the driving of the vehicle may cause a traffic accident.

[0035] In this utility model, during the driving of the vehicle, air enters the interior of the device from the air inlet 5, passes through the air inlet pipe 6, the first protective cover 7, and the second protective cover 8, and then enters the circulation air duct 11 through the adapter pipe 9. The concave surface of the circulation air duct 11 is close to the heating module 12. Therefore, when the air is above the heating module 12 after entering the interior of the circulation air duct 11, it can be heated by the circulation air duct 11 to form hot air and move inside the circulation air duct 11. And since the circulation air duct 11 is overall in an S shape, the air will be heated by the heating module 12 multiple times. During the movement of the hot air inside the circulation air duct 11, it will increase the temperature of the part of the surface of the lens 3 where the heating module 12 is not distributed, so that most of the surface of the lens 3 can be heated, and most of the water mist on the surface of the lens 3 can be removed.

[0036] At the same time, after the air completes the circulation inside the circulation air duct 11, it will be discharged from the air outlet pipe 13 through the exhaust hole 4 and directly blow on the surface of the lens 3, and the water droplets that are not easily atomized on the surface of the lens 3 can be blown away by the exhaust hole 4, further increasing the effect of the device in removing water mist.

[0037] By setting the circulation air duct 11, the device can increase the overall range and effect of removing water mist without adding too many other components driven by energy, which can not only improve driving safety but also enhance the overall user experience.
