Rearview mirror assembly and vehicle

Abstract

This utility model discloses a rearview mirror assembly and a vehicle. The rearview mirror assembly includes: a mirror rod adapted to be connected to the vehicle body; and a mirror housing, with the mirror rod circumferentially disposed around at least a portion of the mirror housing. A lens is disposed on the leeward side of the mirror housing, and the orthographic projection of the windward side of the mirror housing in the vertical direction lies within the orthographic projection of the mirror rod in the vertical direction. Therefore, by ensuring that the orthographic projection of the windward side of the mirror housing in the vertical direction lies within the orthographic projection of the mirror rod in the vertical direction, the windward side of the mirror housing will not protrude outward relative to the mirror rod. This not only makes the force on the windward side of the mirror housing more even, reducing wind noise generated by the rearview mirror assembly, but also improves the flatness of the windward side of the rearview mirror assembly.

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a rearview mirror assembly and a vehicle. Background Technology

[0002] With the development of technology and the improvement of people's living standards, vehicles have become an indispensable means of transportation. Vehicles are equipped with side mirrors on both the left and right sides, which help drivers observe the situation behind the vehicle, thereby ensuring driving safety.

[0003] In related technologies, the unreasonable structural design of the vehicle's outer rearview mirrors leads to high sound power radiation from the outer rearview mirrors, resulting in high wind noise from the vehicle's side windows. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of the present invention is to provide a rearview mirror assembly with a reliable structure that can effectively reduce the sound power radiation of the rearview mirror assembly and reduce wind noise from the vehicle's side windows.

[0005] This utility model further proposes a vehicle.

[0006] The rearview mirror assembly according to this utility model includes: a mirror rod adapted to be connected to a vehicle body; a mirror housing, the mirror rod being arranged around at least a portion of the circumference of the mirror housing, a lens being provided on the leeward side of the mirror housing, and the orthographic projection of the windward side of the mirror housing in the vertical direction being located within the orthographic projection of the mirror rod in the vertical direction.

[0007] Therefore, by making the orthographic projection of the windward side of the mirror housing in the vertical direction fall within the orthographic projection of the mirror rod in the vertical direction, the windward side of the mirror housing will not bulge outward relative to the mirror rod. This not only makes the force on the windward side of the mirror housing more uniform, reducing the wind noise generated by the rearview mirror assembly, but also improves the flatness of the windward side of the rearview mirror assembly.

[0008] In some examples of this utility model, the mirror housing is further provided with a main board, a first side plate, a second side plate, a third side plate, and a fourth side plate. The orthographic projection of the windward side of the main board in the vertical direction is located within the orthographic projection of the mirror rod in the vertical direction. The first side plate and the second side plate are respectively disposed on both sides of the main board in the left and right directions and extend rearward. Compared with the second side plate, the first side plate is closer to the vehicle body in the left and right directions. The third side plate and the fourth side plate are respectively disposed on both sides of the main board in the vertical direction and extend rearward. The mirror rod is connected to the second side plate, the third side plate, and the fourth side plate respectively.

[0009] In some examples of this utility model, the windward side of the motherboard is flush with the windward side of the mirror rod.

[0010] In some examples of this utility model, the motherboard has at least two interconnected rounded corners on one side edge adjacent to the first side plate in the left-right direction to form a wave shape.

[0011] In some examples of this utility model, the motherboard has a first rounded corner and a second rounded corner on one side edge adjacent to the first side plate in the left-right direction. The second rounded corner is connected to the end of the first rounded corner away from the first side plate in the left-right direction, and the second rounded corner is recessed relative to the first rounded corner.

[0012] In some examples of this invention, the radius of the first fillet is smaller than the radius of the second fillet.

[0013] In some examples of this utility model, the radius of the first fillet is set to R1, and R1 satisfies the relationship: 5mm≤R1<10mm.

[0014] In some examples of this utility model, the radius of the second fillet is set to R2, and R2 satisfies the relationship: 10mm≤R2≤15mm.

[0015] In some examples of this utility model, the mirror housing is a one-piece molded structural component.

[0016] The vehicle according to an embodiment of the present invention includes: the rearview mirror assembly described above.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-11 The rearview mirror assembly 100 according to an embodiment of the present invention is described. The rearview mirror assembly 100 can be applied to a vehicle.

[0022] Combination Figures 1-4 As shown, the rearview mirror assembly 100 according to this utility model mainly includes: a mirror rod 10 and a mirror housing 20. The mirror rod 10 is adapted to be connected to the vehicle body, thus securely fixing the rearview mirror assembly 100 to suitable positions on the left and right sides of the vehicle body. This ensures that the rearview mirror assembly 100 will not shake or fall off during vehicle movement, vibration, or exposure to wind and rain, thus ensuring the stability and reliability of the rearview mirror assembly 100.

[0023] Furthermore, the mirror rod 10 is arranged around at least a portion of the mirror housing 20 in the circumferential direction, and the mirror housing 20 has a lens 30 arranged on the leeward side 50. This not only stably fixes the mirror housing 20 and the lens 30 to the mirror rod 10, ensuring the stability and reliability of the structure of the mirror housing 20 and the lens 30, and preventing the mirror housing 20 and the lens 30 from shaking or falling off, but also reduces the impact of airflow, rain, sand and dust on the lens 30 by the leeward arrangement of the lens 30, reducing the wear of the connection parts between the lens 30 and the mirror housing 20 or other structures. At the same time, it also makes it easier for the driver to observe the road conditions behind the vehicle through the lens 30.

[0024] Furthermore, the orthographic projection of the windward side 40 of the mirror housing 20 in the vertical direction lies within the orthographic projection of the mirror rod 10 in the vertical direction. Specifically, in the prior art, the orthographic projection of the windward side 40 of the mirror housing 20 in the vertical direction does not completely overlap with the orthographic projection of the mirror rod 10 in the vertical direction. That is to say, at least a portion of the windward side 40 of the mirror housing 20 protrudes relative to the mirror rod 10. This protruding portion will generate greater wind noise and affect the aesthetics. In this embodiment of the present invention, by making the orthographic projection of the windward side 40 of the mirror housing 20 in the vertical direction fall within the orthographic projection of the mirror rod 10 in the vertical direction, the protruding part of the windward side 40 of the mirror housing 20 relative to the mirror rod 10 can be eliminated. This optimizes the surface design of the windward side 40 of the rearview mirror assembly 100, making the force on the windward side 40 of the rearview mirror assembly 100 more uniform, allowing the airflow to pass around the rearview mirror assembly 100 more smoothly, reducing the generation of turbulence, reducing the sound power radiation of the rearview mirror assembly 100, reducing the noise caused by the surface design of the rearview mirror assembly 100, and also improving the aesthetics of the rearview mirror assembly 100.

[0025] Furthermore, the windward side 40 of the mirror housing 20 will not protrude outward relative to the mirror rod 10. This prevents the windward side 40 of the rearview mirror assembly 100 from being subjected to force only when it collides with the mirror rod 10. This avoids the windward side 40 of the mirror housing 20 protruding outward relative to the mirror rod 10 from being more easily damaged, thus improving the structural reliability of the rearview mirror assembly 100.

[0026] Therefore, by making the orthographic projection of the windward side 40 of the mirror housing 20 in the vertical direction fall within the orthographic projection of the mirror rod 10 in the vertical direction, the windward side 40 of the mirror housing 20 will not protrude outward relative to the mirror rod 10. This not only makes the force on the windward side 40 of the mirror housing 20 more uniform, but also reduces the wind noise generated by the rearview mirror assembly 100 and the side window wind noise of the vehicle, and also improves the flatness of the windward side 40 of the rearview mirror assembly 100.

[0027] Combination Figure 1 , Figure 2 , Figure 5 and Figure 8 As shown, the mirror housing 20 is also provided with a main board 201, a first side plate 202, a second side plate 203, a third side plate 204, and a fourth side plate 205. The orthographic projection of the windward side 40 of the main board 201 in the vertical direction is located within the orthographic projection of the mirror rod 10 in the vertical direction. The first side plate 202 and the second side plate 203 are respectively provided on both sides of the main board 201 in the left and right directions and extend backward. Compared with the second side plate 203, the first side plate 202 is closer to the vehicle body in the left and right directions. The third side plate 204 and the fourth side plate 205 are respectively provided on both sides of the main board 201 in the vertical direction and extend backward. The mirror rod 10 is connected to the second side plate 203, the third side plate 204, and the fourth side plate 205 respectively.

[0028] Specifically, the vertical projection of the windward side 40 of the motherboard 201 is located within the vertical projection of the mirror rod 10. This prevents the windward side 40 of the motherboard 201 from protruding relative to the mirror rod 10, making the force on the windward side 40 of the motherboard 201 more even. It also optimizes the surface design of the windward side 40 of the motherboard 201, allowing airflow to pass more smoothly around the rearview mirror assembly 100, thereby reducing the noise generated by the rearview mirror assembly 100. In addition, it also improves the aesthetics of the rearview mirror assembly 100.

[0029] Furthermore, the first side plate 202 and the second side plate 203 are respectively disposed on both sides of the main plate 201 in the left-right direction and extend rearward, while the third side plate 204 and the fourth side plate 205 are respectively disposed on both sides of the main plate 201 in the up-down direction and extend rearward. The lens rod 10 is connected to the second side plate 203, the third side plate 204, and the fourth side plate 205 respectively. Thus, by making the first side plate 202, the second side plate 203, the third side plate 204, and the fourth side plate 205 all extend rearward, not only can a certain space be formed on the leeward side 50 of the lens housing 20, facilitating the installation and fixing of the lens 30 and protecting the lens 30, but it also facilitates the connection and fixing of the lens housing 20 and the lens rod 10, improving the stability and reliability of the lens housing 20 structure. In addition, the rearward extension of the first side plate 202 allows its surface to conform to the direction of airflow, enabling airflow to flow smoothly along the surface of the first side plate 202.

[0030] Combination Figure 1 , Figure 2 and Figure 4As shown, the windward side 40 of the mainboard 201 is flush with the windward side 40 of the mirror arm 10. Specifically, by making the windward side 40 of the mainboard 201 and the windward side 40 of the mirror arm 10 flush, the surface design of the windward side 40 of the rearview mirror assembly 100 can be optimized, the force on the windward side 40 of the rearview mirror assembly 100 can be more even, the airflow can be more smoothly bypassed by the rearview mirror assembly 100, the noise generated by the rearview mirror assembly 100 can be reduced, and the aesthetics of the rearview mirror assembly 100 can be improved.

[0031] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, at least two interconnected rounded corners 206 are provided on one side edge of the mainboard 201 adjacent to the first side panel 202 in the left-right direction to form a wave shape. Specifically, compared with the setting of a single rounded corner 206, by providing at least two interconnected rounded corners 206 on one side edge of the mainboard 201 adjacent to the first side panel 202 in the left-right direction to form a wave shape, the rounded corners 206 on the windward side 40 of the mirror housing 20 can be smaller. This not only makes the force on the windward side 40 of the mirror housing 20 more uniform, making the mirror housing 20 more in line with the aerodynamic low wind noise design principle, but also reduces the wind noise generated by the rearview mirror assembly 100, and also reduces the distance between the mainboard 201 and the first side panel. The angle between 202 can reduce the size of the orthographic projection of the rearview mirror assembly 100 in the front-rear direction in the left-right direction. This not only helps to increase the distance between the rearview mirror assembly 100 and the vehicle body, avoiding the rearview mirror assembly 100 being too close to the vehicle body and affecting the observation range of the rearview mirror assembly 100, but also prevents the vehicle from appearing too large in the left-right direction due to the increased distance between the rearview mirror assembly 100 and the vehicle body. This can prevent the vehicle from scraping when meeting oncoming traffic, parking, or passing obstacles in narrow road sections.

[0032] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a first rounded corner 2061 and a second rounded corner 2062 are provided on one side edge of the motherboard 201 in the left-right direction adjacent to the first side plate 202. The second rounded corner 2062 is connected to the end of the first rounded corner 2061 that is away from the first side plate 202 in the left-right direction. The second rounded corner 2062 is recessed relative to the first rounded corner 2061.

[0033] Specifically, the motherboard 201 has a first rounded corner 2061 and a second rounded corner 2062 on one side edge adjacent to the first side plate 202 in the left and right directions. This not only makes the force at the connection between the motherboard 201 and the first side plate 202 more uniform and prevents the connection between the motherboard 201 and the first side plate 202 from breaking or deforming due to stress concentration, but also optimizes the surface design of the windward side 40 of the mirror housing 20, reduces the sound power radiation of the mirror housing 20, and thus reduces the wind noise generated by the rearview mirror assembly 100.

[0034] Furthermore, the second rounded corner 2062 is connected to the end of the first rounded corner 2061 that is away from the first side plate 202 in the left and right directions. The second rounded corner 2062 is recessed relative to the first rounded corner 2061. This allows the water flowing to the second rounded corner 2062 of the main board 201 to flow downward along the second rounded corner 2062 when the vehicle speed or wind speed is low, due to the recessed setting of the second rounded corner 2062 and the gravity of the water flow itself. This helps to prevent the water flowing to the main board 201 from flowing towards the lens 30, thus optimizing the water management design of the rearview mirror assembly 100.

[0035] In some embodiments of this utility model, the first rounded corner 2061 and the second rounded corner 2062 are straight or arc-shaped in the vertical direction.

[0036] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the radius of the first rounded corner 2061 is smaller than the radius of the second rounded corner 2062. Specifically, by making the radius of the first rounded corner 2061 smaller than the radius of the second rounded corner 2062, not only can the force on the windward side 40 of the lens housing 20 be more evenly distributed, thus optimizing the surface design of the lens housing 20 and making its surface more in line with the aerodynamic low-wind-noise design principle, but it can also enhance the guiding effect of the second rounded corner 2062 on the water flow, allowing the water flowing to the second rounded corner 2062 of the main board 201 to flow more smoothly downwards along the second rounded corner 2062, which is more effective in preventing the water flowing to the main board 201 from flowing towards the lens 30.

[0037] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the radius of the first fillet 2061 is set to R1, and R1 satisfies the relationship: 5mm ≤ R1 < 10mm. Specifically, if the radius of the first fillet 2061 is less than 5mm, it will not only reduce the guiding effect of the second fillet 2062 on the water flow direction, but may also cause stress concentration at the first fillet 2061; if the radius of the first fillet 2061 is greater than or equal to 10mm, it may increase the size of the orthographic projection of the rearview mirror assembly 100 in the front-rear direction in the left-right direction, thereby increasing the risk of scratches on the rearview mirror assembly 100. Therefore, by making the radius of the first rounded corner 2061 not less than 5mm and not greater than or equal to 10mm, it can not only improve the guiding effect of the second rounded corner 2062 on the direction of water flow, but also help prevent the water flowing to the main board 201 from flowing towards the lens 30, thus preventing stress concentration at the first rounded corner 2061. It can also ensure the rationality of the dimensions of the orthographic projection of the rearview mirror assembly 100 in the front-rear direction in the left-right direction, reducing the risk of scratches on the rearview mirror assembly 100. In addition, it can also help make the surface of the mirror housing 20 more in line with the aerodynamic low wind noise design principle, thus reducing the wind noise generated by the rearview mirror assembly 100.

[0038] Combination Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the central angle corresponding to the first fillet 2061 is set as α, and α satisfies the relationship: 230°≤α≤280°. Specifically, if the central angle corresponding to the first fillet 2061 is less than 230 degrees, it will reduce the guiding effect of the second fillet 2062 on the water flow direction; if the central angle corresponding to the first fillet 2061 is greater than 280 degrees, it will not only affect the overall flatness of the main board 201, but may also cause stress concentration at the first fillet 2061. Therefore, by ensuring that the central angle corresponding to the first rounded corner 2061 is not less than 230 degrees and not greater than 280 degrees, the guiding effect of the second rounded corner 2062 on the water flow direction can be improved, which can help prevent the water flowing to the main board 201 from flowing towards the lens 30. It can also improve the overall flatness of the main board 201, which can prevent stress concentration at the first rounded corner 2061, thereby preventing or reducing the occurrence of breakage or deformation at the first rounded corner. In addition, it can also help make the surface of the mirror housing 20 more in line with the aerodynamic low wind noise design principle, which can help reduce the wind noise generated by the rearview mirror assembly 100.

[0039] Optionally, in some embodiments of this utility model, the radius R1 of the first fillet 2061 can be set to 8mm, and the central angle corresponding to the first fillet 2061 can be set to 250 degrees. It should be noted that the radius R1 of the first fillet 2061 and the central angle α corresponding to the first fillet 2061 can be adjusted according to the specific structure and specific requirements of the rearview mirror assembly 100.

[0040] Combination Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the radius of the second rounded corner 2062 is set to R2, which satisfies the relationship: 10mm≤R2≤15mm. Specifically, if the radius of the second rounded corner 2062 is less than 10mm, it will reduce the guiding effect of the second rounded corner 2062 on the water flow direction, thereby causing more water to flow towards the mirror 30; if the radius of the second rounded corner 2062 is greater than 15mm, it will increase the size of the orthographic projection of the rearview mirror assembly 100 in the front-rear direction in the left-right direction, thereby increasing the risk of scratches on the rearview mirror assembly 100. Therefore, by making the radius of the second rounded corner 2062 not less than 10mm and not more than 15mm, it can not only improve the guiding effect of the second rounded corner 2062 on the direction of water flow, but also help prevent the water flowing to the main board 201 from flowing towards the lens 30. It can also ensure the rationality of the dimensions of the orthographic projection of the rearview mirror assembly 100 in the front-rear direction in the left-right direction, reducing the risk of scratches on the rearview mirror assembly 100. In addition, it can also help make the surface of the mirror housing 20 more in line with the aerodynamic low wind noise design principle, which is conducive to reducing the wind noise generated by the rearview mirror assembly 100.

[0041] Combination Figure 1 , Figure 4 , Figure 5 and Figure 7As shown, the central angle corresponding to the second fillet 2062 is set as β, and β satisfies the relationship: 130°≤α≤180°. Specifically, if the central angle corresponding to the second fillet 2062 is less than 130 degrees, the guiding effect of the second fillet 2062 on the water flow direction will be reduced; if the central angle corresponding to the second fillet 2062 is greater than 180 degrees, it will not only affect the overall flatness of the main board 201, but may also cause stress concentration at the second fillet 2062. Therefore, by ensuring that the central angle corresponding to the second rounded corner 2062 is not less than 130 degrees and not greater than 180 degrees, it is possible not only to improve the guiding effect of the second rounded corner 2062 on the direction of water flow, which can help prevent water flowing to the main board 201 from flowing towards the lens 30, but also to improve the overall flatness of the main board 201, which can prevent stress concentration at the second rounded corner 2062, thereby preventing or reducing the occurrence of breakage or deformation at the second rounded corner 2062. In addition, it can also help make the surface of the mirror housing 20 more in line with the aerodynamic low wind noise design principle, which is conducive to reducing the wind noise generated by the rearview mirror assembly 100.

[0042] Optionally, in some embodiments of this utility model, the radius R2 of the second fillet 2062 can be set to 13mm, and the central angle β corresponding to the second fillet 2062 can be set to 150 degrees. It should be noted that the radius R2 of the second fillet 2062 and the central angle β corresponding to the second fillet 2062 can be adjusted according to the specific structure and specific requirements of the rearview mirror assembly 100.

[0043] Combination Figure 4 , Figure 5 and Figure 8 As shown, the mirror housing 20 is a one-piece molded structural component. Specifically, by making the mirror housing 20 a one-piece molded structural component, not only can the structural strength of the mirror housing 20 be improved and the stress on the mirror housing 20 be made more uniform, but also the airflow can be made to bypass the rearview mirror assembly 100 more smoothly. This allows the surface design of the mirror housing 20 to better conform to the aerodynamic low wind noise design principle, which is conducive to reducing the wind noise generated by the rearview mirror assembly 100. In addition, it can also improve the sealing performance of the mirror housing 20, preventing rainwater, dust, etc. from entering the interior of the mirror housing 20. Furthermore, it can simplify the assembly process and the number of parts of the mirror housing 20, making the production and manufacturing of the mirror housing 20 easier.

[0044] Combination Figure 9 , Figure 10 and Figure 11As shown, this invention uses CFD external flow field simulation to simulate the overall flow field on the outer surface of the vehicle body, thereby obtaining the flow field simulation results for the side window glass surface area. In the prior art, the orthographic projection of the windward side 40 of the mirror housing 20 in the vertical direction does not completely overlap with the orthographic projection of the mirror rod 10 in the vertical direction; that is, at least a portion of the windward side 40 of the mirror housing 20 protrudes relative to the mirror rod 10. By comparing the simulation results of the side window glass surface of the rearview mirror assembly 100 using this invention with the simulation results of the side window glass surface using the rearview mirror structure in the prior art, the effectiveness of the solution of this invention can be demonstrated. Here, CFD in this invention refers to aerodynamics.

[0045] Specifically, in combination Figure 9 and Figure 10 As shown, by performing CFD wind noise steady-state simulation, the sound power cloud maps of the side window glass surface using the existing rearview mirror structure and the rearview mirror assembly 100 of this invention were obtained respectively. Based on the obtained sound power cloud maps, calculus and averaging calculations were performed to obtain the corresponding noise value of the side window glass surface. It can be concluded that compared with the noise value of the side window glass surface using the existing rearview mirror structure, the noise value of the side window glass surface using the rearview mirror assembly 100 of this invention is significantly reduced. The sound power cloud map of the side window glass surface refers to the distribution of sound energy within the side window glass area; areas with higher sound power have higher noise values, and areas with lower sound power have lower noise values.

[0046] Furthermore, combined Figure 11 As shown, by performing CFD wind noise transient simulation and transient calculation, the sound pressure level spectrum analysis diagrams of the side window glass surface using the existing rearview mirror structure and the rearview mirror assembly 100 of this invention were obtained respectively. According to the spectrum analysis results, compared with the spectrum analysis results of the side window glass surface using the existing rearview mirror structure, the overall sound pressure level of the side window glass surface using the rearview mirror assembly 100 of this invention is lower. Furthermore, the sound pressure level of the side window glass surface using the rearview mirror assembly 100 of this invention is reduced by 1.1 to 2.6 dB in the frequency range of 100–5000 Hz, and speech intelligibility is improved by 1.2%. The sound pressure level spectrum analysis diagram represents the sound intensity at different frequencies. The horizontal axis of the sound pressure level spectrum analysis diagram represents frequency, with the unit being Hertz (Hz), and the vertical axis represents sound pressure level, with the unit being decibels (dB).

[0047] Therefore, compared with the rearview mirror structure using the prior art, the rearview mirror assembly 100 of this utility model can effectively reduce the wind noise of the vehicle's side windows.

[0048] The vehicle according to this utility model mainly includes the aforementioned rearview mirror assembly 100. Specifically, since the structure of the rearview mirror assembly 100 is more in line with the aerodynamic low wind noise design principle and has good stability, applying the rearview mirror assembly 100 to a vehicle can reduce vehicle wind noise and improve the vehicle's aesthetics.
