[0004] Therefore, one objective of this utility model is to propose a water-removing structure for removing rainwater from exterior rearview mirrors, which can utilize natural wind power to quickly disperse raindrops on the mirror surface, while reducing the amount of rain falling on the mirror surface, ensuring a clear field of vision in the rearview mirror, guaranteeing driving safety, and being energy-saving and environmentally friendly.

[0005] To achieve the above objectives, the first aspect of this utility model proposes a water-removing structure for removing rainwater from an exterior rearview mirror, comprising an exterior rearview mirror body, including an exterior rearview mirror housing and a rearview element installed within the exterior rearview mirror housing for obtaining a rear view of the vehicle; an air inlet end disposed on a wheel arch, the opening of the air inlet end pointing in the direction of vehicle travel; an air outlet end disposed between the exterior rearview mirror housing and the rearview element; and an air duct for connecting the air inlet end and the air outlet end, wherein external airflow sequentially enters the air duct through the air inlet end and is blown onto the rearview element through the air outlet end.

[0006] In addition, the water-removing structure for removing rainwater from the exterior rearview mirror as proposed above may also have the following additional technical features:

[0007] Specifically, the air duct includes a first duct, a second duct, a third duct, and a fourth duct, wherein the first duct, the second duct, the third duct, and the fourth duct are connected sequentially from bottom to top and together form a continuous sloping gradient. One end of the first duct is connected to the air inlet, and one end of the fourth duct is connected to the air outlet.

[0008] Specifically, the first pipe is arranged on the wheel arch, one end of the second pipe is arranged above the wheel arch, the other end of the second pipe is arranged in the door, the third pipe is arranged in the door, and the fourth pipe is arranged in the exterior rearview mirror housing.

[0009] Specifically, the first pipeline includes a front section pipeline and a rear section pipeline, wherein the air inlet, the front section pipeline and the rear section pipeline are connected sequentially from bottom to top, and the bottom wall of the inner wall of the front section pipeline forms a water flow guiding surface.

[0010] Specifically, the axis of the front section of the duct that connects to one end of the air inlet coincides with the axis of the air inlet, and the angle of inclination α between the axis of the front section of the duct and the horizontal plane is 20-60°.

[0011] Specifically, an air outlet is formed at one end of the air outlet near the rearview element, and the air outlet extends along the edge of the rearview element in a strip-like distribution.

[0012] Specifically, the air outlet end is configured with a flared structure along one end of the fourth pipeline toward the air outlet.

[0013] Specifically, the air outlet is located on top of the rearview element and arranged on the outside of the rearview element.

[0014] Specifically, the longitudinal section of the air outlet is shaped like a horn, and the horn gradually widens from top to bottom towards the rearview element.

[0015] The second aspect of this utility model provides a vehicle, including the water-removing structure for removing rainwater from the exterior rearview mirror as described in the first aspect, a vehicle body, a door, a wheel cover, and a wheel, wherein the door is hinged to the vehicle body, and the water-removing structure is disposed on the door for obtaining a view of the rear of the vehicle; the wheel cover is disposed on the vehicle body; and the wheel is mounted on the vehicle body and arranged adjacent to the wheel cover.

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] (1) During the vehicle's operation, the airflow at the wheel arch is obtained through the air intake end and transmitted to the air outlet end through the air duct. The airflow is then directed to the rearview element through the air outlet end to blow the raindrops on the rearview element away from the mirror surface. At the same time, the blown airflow will also form an air curtain to block the rain, reduce the amount of rain on the mirror surface, ensure the clear view of the mirror surface, reduce driving safety hazards and driving troubles for the driver, and ensure driving safety.

[0019] (2) By arranging the air intake end at the wheel arch and facing the direction of vehicle movement, the dynamic pressure effect generated when the vehicle is moving can be fully utilized. That is, the high-speed airflow forms a positive pressure zone at the air intake end, which enables the air intake end to directly capture the high-speed airflow and form a higher air intake pressure, thereby improving the air intake efficiency. Moreover, it can naturally draw air without the need for additional power support, making it more energy-efficient and environmentally friendly. Attached Figure Description

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0033] The following description, in conjunction with the accompanying drawings, describes a water-removing structure and vehicle for removing rainwater from the exterior rearview mirror according to an embodiment of the present invention.

[0034] During vehicle operation, especially in rainy or snowy weather, raindrops easily accumulate on the exterior rearview mirrors, causing them to become blurry. This severely affects the driver's ability to observe road conditions behind, increasing driving safety hazards and causing considerable inconvenience and distress.

[0035] To solve the above technical problems, such as Figure 1 , Figure 2 As shown, a first aspect of the present invention provides a water removal structure for removing rainwater from an exterior rearview mirror, which may include an exterior rearview mirror body 10, an air inlet 11, an air outlet 12, and an air duct 13.

[0036] The exterior rearview mirror body 10 includes an exterior rearview mirror housing 100 and a rearview element 101. The rearview element 101 is installed inside the exterior rearview mirror housing 100 and is used to obtain the rear view of the vehicle. The exterior rearview mirror body 10 can be a traditional mirror rearview mirror or an electronic rearview mirror, etc. Correspondingly, the rearview element 101 is a lens in a traditional mirror rearview mirror, while it is a camera in an electronic rearview mirror. For ease of description and understanding, the following description will mainly use a traditional mirror rearview mirror as an example, but those skilled in the art should understand that the relevant technical solutions are also applicable to electronic rearview mirrors.

[0037] The air inlet 11 is located on the wheel cover 40, and the opening of the air inlet 11 points in the direction of the vehicle's forward movement.

[0038] As the vehicle moves forward, air flows over the surface of the vehicle body 20 at a high speed. The area near the wheel arch 40, close to the wheel 50, is one of the areas where airflow is most concentrated during vehicle movement. By arranging the air intake 11 at the wheel arch 40 and facing the direction of vehicle movement, the dynamic pressure effect generated during vehicle movement can be fully utilized. That is, the high-speed airflow forms a positive pressure zone at the air intake 11, allowing the air intake 11 to directly capture the high-speed airflow, forming a higher intake pressure, thereby improving intake efficiency.

[0039] Meanwhile, the wheel arch 40 area is one of the areas with relatively complex airflow during vehicle movement. The rotation of the wheel 50 will cause the surrounding air to form vortices and high-speed airflow. Specifically, when the wheel 50 rotates, it will push the air outward and backward. The air intake end 11 is arranged facing the direction of vehicle movement, which can capture this high-speed airflow. Moreover, the airflow in the wheel arch 40 area is relatively stable. Especially when the vehicle is traveling at high speed, it can provide a continuous and high-speed airflow input to the air intake end 11, further improving the efficiency and stability of the air intake end 11.

[0040] The air outlet 12 is located between the exterior rearview mirror housing 100 and the rearview element 101.

[0041] It should be noted that the position of the air outlet 12 between the exterior rearview mirror housing 100 and the rearview element 101 can be selected according to the actual situation. For example, the air outlet 12 can be set between the top of the exterior rearview mirror housing 100 and the rearview element 101, or between the side (left or right side) of the exterior rearview mirror housing 100 and the rearview element 101, or between the bottom of the exterior rearview mirror housing 100 and the rearview element 101. Preferably, the air outlet 12 is set between the top of the exterior rearview mirror housing 100 and the rearview element 101. By utilizing the gravity of the water droplets themselves, and with the air outlet 12 being set at the top, a downward airflow is generated. The synergistic effect of the two greatly improves the efficiency of water droplet removal.

[0042] The air duct 13 is used to connect the air inlet 11 and the air outlet 12. That is, by connecting one end of the air duct 13 to the air inlet 11 and the other end of the air duct 13 to the air outlet 12, the air inlet 11 and the air outlet 12 are connected, so that the airflow obtained by the air inlet 11 is transmitted to the air outlet 12 through the air duct 13 and blown onto the rearview element 101 through the air outlet 12 to quickly remove raindrops on the rearview element 101.

[0043] In practice, the connection between the end of the air duct 13 and the air inlet 11 or the air outlet 12 can be achieved by means of direct plug-in, heat fusion, flange connection, etc. For example, in the form of direct plug-in, the end of the air duct 13 is designed to match the shape of the air inlet 11 or the air outlet 12, and then the two are tightly connected by plug-in.

[0044] Specifically, during vehicle operation, especially in rainy or snowy weather, a large number of raindrops tend to accumulate on the rearview element 101 of the exterior rearview mirror body 10, causing the mirror surface to become blurry. At this time, airflow is obtained from the wheel arch 40 through the air inlet 11 and transmitted to the air outlet 12 through the air duct 13. The airflow is then directed to the rearview element 101 through the air outlet 12 to blow the raindrops on the rearview element 101 away from the mirror surface. At the same time, the blown airflow also forms an air curtain to block the rain, reducing the amount of rain on the mirror surface, ensuring a clear view of the mirror, reducing driving safety hazards, and ensuring driving safety.

[0045] Compared to traditional methods, manually wiping the rearview element 101 by the driver while parking or driving greatly improves driving safety and eliminates the risk of rear-end collisions caused by parking. At the same time, compared to another method of evaporating raindrops by electrically assisted heating of the rearview element 101, it is more efficient, requires no additional electricity or complex structure, uses natural ventilation, is more energy-saving and environmentally friendly, and is also cheaper.

[0046] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the air duct 13 includes a first duct 130, a second duct 131, a third duct 132, and a fourth duct 133.

[0047] The first pipe 130, the second pipe 131, the third pipe 132, and the fourth pipe 133 are connected sequentially from bottom to top and together form a continuous sloping slope. One end of the first pipe 130 is connected to the air inlet 11, and one end of the fourth pipe 133 is connected to the air outlet 12, thus forming a sloping drainage slope. When the vehicle is wading through water, due to gravity, water is unlikely to flow backward into the sloping pipes, and gravity can also quickly drain the water that has entered the pipes, thereby greatly reducing the risk of water backflowing into the air duct pipe 13. The sloping direction is from the wheel cover 40 toward the door 30.

[0048] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the first pipe 130 is arranged on the wheel arch 40, one end of the second pipe 131 is arranged above the wheel arch 40, and the other end of the second pipe 131 is arranged in the door 30. Therefore, the middle part of the second pipe 131 will be located at the hinge position between the door 30 and the body 20. The second pipe 131 is a flexible hose with a certain degree of flexibility. When the door 30 is opened, the second pipe 131 can be stretched and bent appropriately, which will not hinder the normal operation of the door 30, but will also maintain the smooth flow of air.

[0049] The hose can typically be made of plastic, silicone, rubber, or a flexible material with a braided reinforcement layer. For example, a corrugated pipe made of plastic can be used. With its unique corrugated structure, the corrugated pipe can easily cope with the stretching and bending requirements when the door is opened 30 degrees without causing the pipe to break or the airflow to be obstructed. Even when bent, the inner cavity of the corrugated pipe can remain relatively stable, avoiding the problem of airflow obstruction caused by pipe deformation.

[0050] The third pipe 132 is installed in the door 30, and the fourth pipe 133 is installed in the exterior rearview mirror housing 100. The first pipe 130, the third pipe 132, and the fourth pipe 133 are all rigid pipes. Rigid pipes have high mechanical strength and can withstand the vibration, impact, and pressure of the external environment during vehicle operation. They are not easily deformed or damaged. At the same time, the rigid pipes themselves have high strength and can maintain stability without additional support components, which simplifies the installation structure. In addition, the inner wall of the rigid pipe is smooth and the cross-sectional shape is stable, resulting in low resistance when airflow passes through, which can maximize the airflow speed and air volume. The rigid pipes can be made of metal pipes or high-strength plastic pipes, etc.

[0051] Specifically, during vehicle operation, airflow enters through the air inlet 11 and passes through the first pipe 130, the second pipe 131, the third pipe 132 and the fourth pipe 133 in sequence, and is then directed to the rearview element 101 through the air outlet 12.

[0052] In one embodiment of this utility model, such as Figure 3 As shown, the first pipeline 130 includes a front pipeline 1300 and a rear pipeline 1301. The air inlet 11, the front pipeline 1300 and the rear pipeline 1301 are connected sequentially from bottom to top. The bottom wall of the inner wall of the front pipeline 1300 forms a water flow guiding surface.

[0053] It should be noted that the water flow guiding surface is an arc-shaped surface that bends upwards towards the second pipe 131. Simultaneously, the front pipe 1300 and the rear pipe 1301 together form a serpentine bend that slopes upwards towards the second pipe 131. The bending directions of the front pipe 1300 and the rear pipe 1301 are opposite, and the continuous bend slope design avoids any meandering sections. This design ensures that the water flow has no stagnation points through a continuous slope in a single direction, and is driven outwards by gravity throughout the entire process.

[0054] In the above design, the upward-sloping design of the air inlet 11, the front pipe 1300, and the rear pipe 1301 creates a continuous, curved slope in the first pipe 130, which utilizes a water flow guiding surface combined with gravity drainage principles. When a vehicle is wading through water, even if a small amount of water enters the first pipe 130 through the air inlet 11, the water flow changes direction due to the upward-curving water flow guiding surface and flows back out of the vehicle along the slope, preventing backflow into the air duct. Furthermore, the absence of a bend eliminates the possibility of water accumulation and further reduces the risk of water intrusion into the air duct.

[0055] Furthermore, such as Figure 3 As shown, the axis of the end of the front pipe 1300 connected to the air inlet 11 coincides with the axis of the air inlet 11. It can be understood that the coincidence of the axes indicates that the port between the end of the front pipe 1300 connected to the air inlet 11 and the air inlet 11 is aligned and there is no misalignment. That is, when a vehicle passes through the water at high speed, the water flow may enter the front pipe 1300 from the air inlet 11 due to inertial impact. When the water flow in the front pipe 1300 is drained by gravity, the connection port is aligned with the axis of the air inlet 11, so the drainage path remains unobstructed and will not encounter any obstacles, thus ensuring the smoothness and efficiency of drainage.

[0056] The inclination angle α between the axis of the front section of the pipeline 1300 and the horizontal plane is 20-60°. The inclination angle α can be 20°, 21°, 22°, etc., and can be set according to the actual situation. No specific limit is made here.

[0057] An inclination angle of 20-60° can fully utilize gravity to allow water entering the front-end pipe 1300 to be discharged quickly. An angle that is too small may result in insufficient drainage speed and water stagnation; an angle that is too large may increase the difficulty of arranging the front-end pipe 1300 and negatively affect airflow transmission, thereby affecting the airflow transmission effect.

[0058] In one embodiment of this utility model, such as Figure 5 and Figure 6 As shown, an air outlet 120 is formed at the end of the air outlet 12 near the rearview element 101. The air outlet 120 extends along the edge of the rearview element 101 in a strip-like distribution. It can be understood that the strip-like (elongated) distribution of the air outlet 120 can expand the coverage area of ​​the airflow on the rearview element 101, thereby ensuring that the airflow covers the rearview element 101, achieving comprehensive cleaning, and thus improving the cleaning effect on the rearview element 101.

[0059] Furthermore, such as Figure 1 As shown, the air outlet 12 is arranged in a flared shape along one end of the fourth pipe 133 toward the air outlet 120.

[0060] It should be noted that the flared structure has a smaller opening at one end (the end connected to the fourth pipe 133) and a larger opening at the other end (at the air outlet 120). The diameter or width of the flared part gradually increases from the connection end to the outlet end.

[0061] In the above scheme, the flared structure can diffuse the concentrated flow of air from the fourth pipe 133 into a wide flow, ensuring that the airflow evenly covers the entire surface of the rearview element 101, avoiding local airflow that is too strong or too weak, and the flared structure can make the airflow transition smoothly from the fourth pipe 133 to the air outlet 120, ensuring efficient transmission.

[0062] In one embodiment of this utility model, such as Figure 6 As shown, the air outlet 120 is located on the top of the rearview element 101 and is arranged on the outside of the rearview element 101.

[0063] In the above scheme, the water droplets flow downward naturally under the action of gravity, while the air outlet 120 is set at the top, generating a downward airflow that further pushes the water droplets off the surface of the rearview element 101. The synergistic effect of the two greatly improves the efficiency of water droplet removal.

[0064] In one embodiment of this utility model, such as Figure 6 As shown, the longitudinal section of the air outlet 120 is shaped like a trumpet, with the trumpet gradually widening from top to bottom towards the rearview element 101. The air outlet 12 can be set parallel to the mirror surface. In this case, the trumpet structure of the air outlet 120, with its characteristic of gradually widening from top to bottom towards the rearview element 101, not only ensures that some airflow can directly blow onto the mirror surface, enhancing the airflow rate of the mirror surface, but also allows another part of the airflow to form a blocking wind curtain in front of the mirror, blowing raindrops away from the mirror surface, thereby reducing rain falling on the mirror surface and further ensuring the visual clarity of the exterior rearview mirror body 10.

[0065] Furthermore, such as Figure 6 As shown, the air outlet angle b of the air outlet 120 is 10-16°. It can be understood that the air outlet angle b is half of the air outlet angle of the air outlet 120. For example, the air outlet angle b is 10°, 11°, 12°, 13°, etc., and the entire complete air outlet angle of the air outlet 120 is 20-32°.

[0066] In the above scheme, when the air outlet angle b is within the range of 10-16°, the airflow can cover the entire mirror surface of the rearview element 101 at a suitable angle, ensuring that every part of the mirror surface receives uniform airflow. This also ensures the formation of an air curtain in front of the mirror. Furthermore, a suitable air outlet angle helps enhance the interaction between the airflow and the mirror surface, thereby improving cleaning efficiency. If the angle is too small, the airflow may be too concentrated, leading to over-cleaning in certain areas; conversely, if the angle is too large, the airflow may be too dispersed, affecting the cleaning effect. An angle range of 10-16° can effectively balance these two factors.

[0067] A second aspect of the present invention provides a vehicle comprising a water-removing structure for removing rainwater from the exterior rearview mirror as described in the first aspect above, a vehicle body 20, a door 30, a wheel cover 40, and a wheel 50.

[0068] The door 30 is hinged to the body 20, and a water-removing structure is installed on the door 30 to obtain the rear view of the vehicle. The wheel cover 40 is installed on the body 20, and the wheel 50 is installed on the body 20 and arranged adjacent to the wheel cover 40.

[0069] Furthermore, such as Figure 4 As shown, a clearance groove 300 is provided at the hinge of the door 30 near the body 20, and part of the second pipe 131 is located in the clearance groove 300.

[0070] In the above solution, by setting the clearance groove 300, the second pipe 131 is located in the clearance groove 300 when the door 30 is closed, avoiding direct compression by the hinge or the door 30 frame. At the same time, the second pipe 131 is designed as a flexible hose, ensuring that the second pipe 131 only undergoes moderate bending rather than compression when the door 30 is opened and closed, thereby ensuring the smoothness of airflow transmission in the second pipe 131.

[0071] The vehicle provided by this utility model, having the water-removing structure for removing rainwater from the exterior rearview mirrors as described in the above embodiments, possesses all the beneficial effects of the aforementioned water-removing structure for removing rainwater from the exterior rearview mirrors.
