Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a rearview mirror mounting structure and a vehicle. BACKGROUND

[0002] In recent years, vehicle noise has caused great harm to the environment. While vehicles bring us modern material civilization, they also bring social problems such as environmental noise pollution. According to the sound generation mechanism of the noise source, vehicle noise mainly has two types: mechanical noise and aerodynamic noise. When the vehicle is running at high speed, aerodynamic noise is particularly obvious. Aerodynamic noise is caused by the interaction between gas flow or the interaction between gas and solid. It includes three aspects: impact noise caused by air entering the vehicle through the gaps or holes of the vehicle body, vortex noise caused by air flowing through the convex parts of the vehicle body, and friction noise caused by air and the vehicle body. Among them, the noise caused by the rearview mirror is an important part of the aerodynamic noise of the vehicle.

[0003] In the prior art, due to the imperfect design of the rearview mirror structure, the vehicle often causes a large noise during driving, which greatly causes the trouble of the passengers. SUMMARY

[0004] The main purpose of the present application is to provide a rearview mirror mounting structure, which aims to reduce the aerodynamic noise of the vehicle.

[0005] To achieve the above purpose, the rearview mirror mounting structure provided by the present application is installed on a vehicle, which includes a vehicle body, a side window installed on the vehicle body, and comprises:

[0006] A mirror shell is used for installing on the vehicle body and located near the side window. The mirror shell has a first side surface close to the side window, and the included angle formed by the first side surface and the side window is less than or equal to a first preset angle.

[0007] Optionally, the first side surface is arranged in parallel with respect to the side window.

[0008] Optionally, the distance between the first side surface and the side window is greater than 50mm and less than or equal to 100mm.

[0009] Optionally, the mirror shell has a second side surface away from the side window, and the included angle between the second side surface and the first side surface is less than or equal to a second preset value.

[0010] Optionally, the second side surface is arranged in parallel with respect to the first side surface.

[0011] Optionally, the mirror housing has a first cross-section along the horizontal direction, and the outer contour line of the first cross-section includes a first line segment, a second line segment, a third line segment and a fourth line segment connected in sequence, and the first line segment is the outer contour line of the first side surface, the fourth line segment is the outer contour line of the second side surface, and the second line segment and the third line segment are both curves.

[0012] Optionally, the third line segment is a cubic curve.

[0013] Optionally, the vehicle also includes a lens, the mirror housing has an opening, the lens is installed at the opening, the mirror housing has a second cross-section along the vertical direction, the outer contour line of the second cross-section includes a fifth line segment and a sixth line segment, one end of the fifth line segment is close to the opening, and the other end is connected to the sixth line segment, and the sixth line segment is a curve.

[0014] Optionally, the fifth line segment is arranged horizontally; and / or,

[0015] The length of the fifth line segment is greater than or equal to 10 mm and less than or equal to 30 mm; and / or,

[0016] The sixth line segment is a cubic curve.

[0017] The present invention further provides a vehicle comprising a vehicle body, a side window mounted on the vehicle body, and the rearview mirror mounting structure as described above, wherein the rearview mirror mounting structure is mounted on the vehicle body or the side window.

[0018] The technical solution of the present invention is to secure the mirror housing to the vehicle body, mount the side window to the vehicle body, and mount the rearview mirror near the side window. The mirror housing has a first side surface proximate to the side window, and the angle formed between the first side surface and the side window is less than or equal to a first predetermined angle. The first side surface guides airflow, causing airflow passing between the vehicle body and the rearview mirror to flow along the extension direction of the rearview mirror, i.e., along the first side surface parallel to the side window or away from the side window. The angle formed between the first side surface 131 and the side window is less than or equal to the first predetermined angle. The first predetermined angle is generally greater than or equal to 1° and less than or equal to 12°. The side window is tilted relative to the vehicle's axis of symmetry, and the distance from the side window to the axis of symmetry increases from the front of the vehicle to the rear of the vehicle. The degree of inclination of the first side surface relative to the axis of symmetry is greater than or equal to the degree of inclination of the side window relative to the axis of symmetry, thereby reducing the possibility of airflow passing through the rearview mirror striking the side window. If the angle between the first side surface and the side window is greater than a first predetermined angle, the first side surface is tilted too far relative to the vehicle's plane of symmetry, potentially entangled with the airflow from the exhaust surface, generating vortices and causing significant wind noise. By designing the surface contour of the mirror housing, the airflow is directed along the rearview mirror housing, reducing the likelihood of airflow striking the side window and thereby reducing the vehicle's aerodynamic noise.

[0029] With the rapid development of the vehicle industry, the continuous popularization of vehicles, people's requirements for vehicle quality are getting higher and higher, and the vehicle 100 often produces a large amount of aerodynamic noise in the driving process, and a large part of the aerodynamic noise is caused by the rearview mirror. The general structure of the rearview mirror includes a mirror seat 120 and a mirror shell 130, the mirror seat 120 is installed on the vehicle body 110, and the mirror shell 130 is installed on the mirror seat 20. The airflow brought by the vehicle 100 in driving will have a large impact on the rearview mirror. If the rearview mirror shell 130 is designed unreasonably, it is difficult to guide the airflow to flow well, not only makes the airflow hit the rearview mirror shell 130 to produce noise, but also easily makes the airflow produce vortex on the rearview mirror to emit noise. And because the rearview mirror is generally installed near the side window 111, the shape and installation position of the rearview mirror are very important. If the shape and installation position of the rearview mirror are designed unreasonably, it is likely to cause the airflow to impact the glass and emit a large amount of noise, so that the people in the vehicle are always disturbed by the noise, affecting the experience of the passengers.

[0030] And the rearview mirror is an important safety accessory of the vehicle 100 in the driving process, which can facilitate the driver to observe the driving environment and reduce the blind area. However, because the rearview mirror is installed outside the vehicle, it is easy to cause the rearview mirror lens to be blurred when encountering rainy, snowy or foggy weather, so that the driver cannot observe the road conditions through the rearview mirror. In order to reduce this situation, in the prior art, the air supply cavity and the air outlet can automatically form an air wall at the opening position (i.e. the front of the lens) during the driving of the vehicle 100, thereby reducing the influence of the external environment on the glass assembly and improving the visibility of the rearview mirror in bad weather. The specific structure can refer to the patent with the patent number CN108189760A. Thus, the rearview mirror air outlet surface is formed. During driving, the airflow flowing through the surface of the shell is easy to interweave with the airflow of the air outlet surface, producing a large amount of noise.

[0031] Therefore, the present application provides a rearview mirror mounting structure, which effectively improves the noise generated by the vehicle 100 during driving by limiting the shape and mounting position of the rearview mirror.

[0032] In the embodiment of the present application, as shown in Figure 1 the rearview mirror mounting structure comprises a mirror housing 130, which is mounted on the vehicle body 110 and located near the side window 111. The mirror housing 130 has a first side surface 131 near the side window 111, and the included angle between the first side surface 131 and the side window 111 is less than or equal to a first preset angle.

[0033] The rearview mirror generally comprises a mirror base 120 and a mirror housing 130. The mirror base 120 is mounted on the vehicle body, and the mirror housing 130 is mounted on the mirror base 120. A mirror lens 140 is installed in the mirror housing 130 to facilitate the user to observe the surrounding environment through the mirror lens. The mirror housing 130 can drive the mirror lens to rotate relative to the mirror base 120 to adjust the reflection angle of the rearview mirror, which is convenient for the driver to observe the driving environment. The rearview mirror is generally installed near the side window 111, that is, the mirror housing 130 can be arranged opposite to the side window 111 or offset from the side window 111. The first side surface 131 is often arranged at an angle with the plane of the side window 111. The angle formed by the first side surface 131 in other embodiments and the plane of the side window 111 is temporarily referred to as the first preset angle. The first preset angle is generally greater than or equal to 1° and less than or equal to 12°, that is, the first preset angle can be 1°, 4°, 7°, 10°, 12°, etc. The angle formed by the first side surface 131 in this embodiment and the plane of the side window 111 is referred to as the first included angle. The first included angle is less than or equal to the first preset angle. The first side surface 131 has a guiding effect on the airflow, so that the airflow flowing between the vehicle body 110 and the rearview mirror flows along the extension direction of the rearview mirror, that is, flows parallel to the side window 111 or flows away from the side window 111, thereby reducing the possibility of the airflow flowing through the rearview mirror hitting the side window 111. According to the structure of the vehicle 100, the vehicle 100 is generally left-right symmetrical, and the side windows 111 are symmetrically arranged relative to the symmetry axis. The side window 111 is inclined relative to the symmetry axis, and the distance from the side window 111 to the symmetry axis increases from the head of the vehicle 100 to the tail of the vehicle 100. The inclination of the first side surface 131 relative to the symmetry axis is greater than or equal to the inclination of the side window 111 relative to the symmetry axis. The wake flowing out of the first side surface 131 is not intertwined with the airflow flowing out of the air outlet surface due to the guiding effect of the first side surface 131, thereby reducing the possibility of vortex or impact on the side window 111 at the rearview mirror and reducing the possibility of noise generated by the rearview mirror. If the angle between the first side surface 131 and the side window 111 is greater than the first preset angle, the inclination of the first side surface 131 relative to the symmetry surface of the vehicle is too large, which may cause vortex due to the entanglement of the airflow of the air outlet surface, and generate relatively large wind noise.

[0034] The technical solution of the present invention is to fix a mirror housing 130 to a vehicle body 110, and to attach a side window 111 to the vehicle body 110. The rearview mirror is mounted near the side window 111. The mirror housing 130 has a first side surface 131 proximate to the side window 111. This first side surface 131 guides airflow, causing airflow between the vehicle body 110 and the rearview mirror to flow along the extension direction of the rearview mirror, i.e., along the first side surface 131, parallel to the side window 111, or away from the side window 111. Furthermore, the angle formed between the first side surface 131 and the side window 111 is less than or equal to a first predetermined angle. The first predetermined angle is generally greater than or equal to 1° and less than or equal to 12°. The side window 111 is tilted relative to the axis of symmetry of the vehicle 100, and the distance from the side window 111 to the axis of symmetry increases from the front of the vehicle 100 to the rear of the vehicle 100. The inclination of the first side surface 131 relative to the axis of symmetry is greater than or equal to the inclination of the side window 111 relative to the axis of symmetry, thereby reducing the likelihood of airflow passing through the rearview mirror striking the side window 111. If the angle between the first side surface 131 and the side window 111 is greater than a first predetermined angle, the inclination of the first side surface 131 relative to the vehicle's plane of symmetry is too great, potentially entangled with airflow from the exhaust surface, generating vortices and causing significant wind noise. By designing the surface profile of the mirror housing 130, the direction of airflow on the rearview mirror housing 130 is guided, thereby reducing the likelihood of airflow striking the side window 111 and thereby reducing the aerodynamic noise of the vehicle 100.

[0035] Furthermore, the first side surface 131 is arranged parallel to the side window 111 .

[0036] Furthermore, the distance between the first side surface 131 and the side window 111 is greater than or equal to 50 mm and less than or equal to 100 mm. Figure 2 As shown, the distance between the first side surface 131 and the side window 111 is d1. Compared to the prior art, this distance is further increased. This not only reduces the possibility of airflow passing through the first side surface 131 striking the side window 111, but also increases the distance between the rearview mirror and the side window 111, thereby directing noise generated by the rearview mirror away from the side window 111 and reducing noise inside the vehicle. If the distance between the first side surface 131 and the side window 111 is less than 50 mm, airflow passing through the first side surface 131 may strike the side window 111. If the distance between the first side surface 131 and the side window 111 is greater than or equal to 100 mm, the rearview mirror's mounting configuration may be affected.

[0037] The distance between the first side surface 131 and the side window 111 may be 50 mm, 70 mm, 90 mm, 100 mm, etc. Of course, in other embodiments, the distance between the first side surface 131 and the side window 111 may also be less than 50 mm or greater than 100 mm.

[0038] With reference to Figure 1 And Figure 2 In an embodiment, the mirror housing 130 has a second side surface 132 away from the side window 111, and the second side surface 132 forms an angle with the first side surface 131, and the angle is less than or equal to a second preset value. In other embodiments, the angle between the first side surface 131 and the second side surface 132 is set as the second preset angle, and the second preset angle is generally greater than or equal to 1° and less than or equal to 12°, i.e., the second preset angle can be 1°, 4°, 7°, 10°, 12°, etc. The angle between the first side surface 131 and the second side surface 132 in this embodiment is set as the second angle, which is less than or equal to the second preset angle. The second side surface 132 also has a guiding effect on the airflow, so that the airflow flows along the extension direction of the second side surface 132, reducing the possibility of vortex flow on the mirror housing 130, thereby reducing the noise of the rearview mirror. The wake flow out of the second side surface 132 will not be intertwined with the wake flow out of the air outlet due to the guiding effect of the second side surface 132, thereby reducing the possibility of noise generation of the rearview mirror.

[0039] Further, the second side surface 132 is arranged parallel to the first side surface 131. The parallel arrangement of the first side surface 131 and the second side surface 132 can also improve the coordinated and aesthetic appearance of the outer contour of the mirror housing 130.

[0040] With reference to Figures 1 to 3 With the ground as the reference system, a three-dimensional coordinate system is established, the direction in which the X-axis is located is set as the length direction of the vehicle 100, the direction in which the Y-axis is located is set as the width direction of the vehicle 100, and the direction in which the Z-axis is located is set as the height direction of the vehicle 100. The plane formed by the X-axis and the Y-axis is parallel to the ground, the plane formed by the X-axis and the Z-axis, and the plane formed by the Y-axis and the Z-axis are all arranged perpendicular to the ground, and the plane formed by the X-axis and the Z-axis is the vertical plane.

[0041] In an embodiment, with reference to Figure 1 And Figure 2The mirror housing 130 has a first cross section in a horizontal direction, and the outer contour line of the first cross section comprises a first line segment 133, a second line segment 134, a third line segment 135 and a fourth line segment 136 connected in sequence, and the first line segment 133 is the outer contour line of the first side surface 131, the fourth line segment 136 is the outer contour line of the second side surface 132, and the second line segment 134 and the third line segment 135 are both curves. As shown in the figure, the first cross section is the A-A cross section, and the first cross section is parallel to the plane formed by the X axis and the Y axis, that is, it is arranged horizontally. The outer contour line of the mirror housing 130 at the first cross section can be divided into a first line segment 133, a second line segment 134, a third line segment 135 and a fourth line segment 136 connected in sequence, and the first line segment 133 is the outer contour line of the first side surface 131, the fourth line segment 136 is the outer contour line of the second side surface 132, and the second line segment 134 and the third line segment 135 are both curves. The outer contour line of the mirror housing 130 at the first cross section is a curve as a whole, and a plurality of first cross sections are arranged along the extension direction of the Z axis, and the plurality of first cross sections are arranged in sequence and jointly limit the spatial shape of the mirror housing 130, so that the mirror housing 130 is a smooth curved surface as a whole, so that the airflow is easy to flow along the outer contour line of the mirror housing 130, and the smooth curved surface is not easy to form vortex flow on the mirror housing 130, thereby reducing the noise of the rearview mirror.

[0042] The third line segment 135 is a cubic curve, that is, the line type of the third line segment 135 meets the requirements of a cubic curve, and a plurality of cubic curves jointly constitute a curved surface, so that the curved surface of the mirror housing 130 can effectively guide the flow of the airflow. According to the wind receiving condition of the surface of the mirror housing 130, the mirror housing 130 can be divided into a windward area on the wind side and a leeward area away from the wind side, and the curved surface formed by the plurality of third line segments 135 is located in the windward area, so that the airflow does not separate when flowing through the outer contour surface formed by the third line segment 135, thereby further increasing the guiding effect of the mirror housing 130 on the airflow and reducing the possibility of noise generated by the rearview mirror.

[0043] To further limit the outer contour of the mirror housing 130, in an embodiment, in combination with reference to Figures 1 to 3The rearview mirror further comprises a lens, the mirror housing 130 has an opening, the lens is installed at the opening, the mirror housing 130 has a second cross section in the vertical direction, an outer contour line of the second cross section comprises a fifth line segment 137 and a sixth line segment 138, one end of the fifth line segment 137 is close to the opening, the other end is connected to the sixth line segment 138, and the sixth line segment 138 is a curve. As shown in the figure, the second cross section is the B-B cross section, the second cross section is parallel to the plane formed by the X axis and the Z axis, that is, it is vertically arranged. The outer contour line of the mirror housing 130 at the second cross section comprises the fifth line segment 137 and the sixth line segment 138 connected in sequence, one end of the fifth line segment 137 is close to the opening, the other end is connected to the sixth line segment 138, and the sixth line segment 138 is a curve. The plane where the fifth line segment 137 and the sixth line segment 138 are located is also located in the windward area, and a plurality of second cross sections are arranged along the extension direction of the Y axis, the plurality of second cross sections are arranged in sequence and staggered with the plurality of first cross sections, and jointly limit the spatial shape of the mirror housing 130, so that the mirror housing 130 as a whole presents a smooth curved surface, so that the airflow is easy to flow along the outer contour line of the mirror housing 130, and the smooth curved surface is not easy to form vortex on the mirror housing 130, thereby reducing the noise of the rearview mirror.

[0044] Further, in an embodiment, the fifth line segment 137 is horizontally arranged. A plurality of fifth line segments 137 are arranged in sequence, and jointly form a horizontal plane at the top of the mirror housing 130, which can effectively guide the flow of the airflow, so that the airflow flows along the extension direction of the second side surface 132, reduces the possibility of vortex formed on the mirror housing 130, thereby reducing the noise of the rearview mirror. And the wake flow out of the horizontal plane will not be intertwined with the wake flow out of the air outlet surface due to the guiding action of the second side surface 132, thereby reducing the possibility of noise generated by the rearview mirror.

[0045] Further, the length of the fifth line segment 137 is greater than or equal to 10 mm and less than or equal to 30 mm. If the length of the fifth line segment 137 is greater than 30 mm, it may make the distance of the horizontal plane too long, so that the thickness of the rearview mirror is too large, or affect the transition connection between the horizontal plane and the plane where the sixth line segment 138 is located, affect the overall contour of the mirror housing 130, and increase the noise; if the length of the fifth line segment 137 is less than 10 mm, it may make the distance of the horizontal plane too short, thereby making it difficult for the horizontal plane to well guide the flow of the airflow.

[0046] Wherein, the length of the fifth line segment 137 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc. Of course, in other embodiments, the length of the fifth line segment 137 can also be less than 10 mm or greater than 30 mm.

[0047] In an embodiment, the length of the fifth line segment 137 is 20 mm. In actual application, through repeated tests, when the length of the fifth line segment 137 is 20 mm, the guiding effect on the airflow is best.

[0048] And the sixth line segment 138 is a cubic curve, that is, the line type of the sixth line segment 138 meets the requirements of the cubic curve, and the plurality of cubic curves collectively constitute a curved surface, so that the mirror shell 130 curved surface can effectively guide the flow of the airflow, and the curved surface formed by the plurality of the sixth line segment 138 is also located in the windward area, so that the airflow does not separate when flowing through the outer contour surface formed by the sixth line segment 138, thereby further increasing the guiding effect of the mirror shell 130 on the airflow and reducing the possibility of noise generated by the rearview mirror.

[0049] The present application also proposes a vehicle, which comprises a vehicle body, a side window 111 and a rearview mirror mounting structure mounted on the vehicle body. The specific structure of the rearview mirror mounting structure is described above.
