[0002] There are two main installation methods for the outside rearview mirror: one is arranged at the triangular window position of the front door, which is not friendly to the front row driving position and is not beautiful in appearance; the second is arranged at the outer plate position of the door, which causes the mirror arm of the outside rearview mirror to be not flush with the window sill line, and the concave feature formed by the rearview mirror and the corner window increases the wind noise and is easy to vibrate under the action of wind resistance. Therefore, it is necessary to design an outside rearview mirror mounting structure which can ensure that the mirror arm of the outside rearview mirror is flush with the window sill line and the mounting structure is reliable.

[0011] In combination with the first aspect, in an embodiment, the exterior mirror mounting plate body is located between the exterior mirror patch plate and the exterior water cutting reinforcing plate. The exterior water cutting reinforcing plate extends on the inner panel along the X direction of the whole vehicle coordinate system. The sum of the thicknesses of the exterior mirror mounting plate body, the exterior mirror patch plate, and the exterior water cutting reinforcing plate is less than or equal to a first set thickness threshold value. The thicknesses of the exterior mirror mounting plate body, the exterior mirror patch plate, and the exterior water cutting reinforcing plate are a first thickness, a second thickness, and a third thickness respectively, the first thickness is less than the second thickness, and the first thickness is less than the third thickness.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the application clearer, the technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0019] Referring to Figures 1 to 6 The embodiment of the application provides an automobile outside rearview mirror mounting structure and an automobile thereof, which can solve the problems of poor appearance effect of outside rearview mirror installation, increased wind noise after installation, and easy vibration under the action of wind resistance in the related art.

[0020] There are two main installation methods for the outside rearview mirror: one is arranged at the triangular window position of the front door, which is not friendly to the front row driving position view and is not aesthetically pleasing; the second is arranged at the outer plate position of the door, which causes the mirror arm of the outside rearview mirror to be not flush with the window sill line, and the concave feature formed by the rearview mirror and the corner window increases the wind noise and is easy to vibrate under the action of wind resistance. Therefore, it is necessary to design an outside rearview mirror mounting structure that can ensure that the mirror arm of the outside rearview mirror is flush with the window sill line and the mounting structure is reliable.

[0021] The first aspect, the application embodiment provides a kind of automobile outside rearview mirror mounting structure, it includes: door sheet metal system 3, window sill outer water cut 4 and outside rearview mirror body 1, door sheet metal system 3 includes outside rearview mirror mounting plate assembly 31, outside rearview mirror mounting plate assembly 31 includes multiple mutually lapping reinforcing plates, multiple mutually lapping reinforcing plates are overlapped in set position;Window sill outer water cut 4 is set on door sheet metal system 3;Outside rearview mirror body 1 is connected on door sheet metal system 3, and the installation exposed surface of outside rearview mirror body 1 is flush with window sill outer water cut 4;Wherein, on outside rearview mirror mounting plate assembly 31, the contact point of outside rearview mirror body 1 and outside rearview mirror mounting plate assembly 31 forms first installation point connecting line along the Z direction of whole vehicle coordinate system, the distance between overlapped region and first installation point connecting line is less than or equal to first set threshold.

[0022] In the application, the installation exposed surface of the outside rearview mirror body 1 is flush with the window sill outer water cut 4, eliminating the visual sense of misplacement caused by the edge, making the door line smooth, and the overall appearance more coordinated; the window sill outer water cut 4 serves as the lower boundary of the glass, and the flush of the outside rearview mirror body 1 with the window sill outer water cut 4 can avoid blocking the transparent area of the triangular window 2, enhance the openness of the rearview field of the driver, and improve the driving safety; by setting the overlapped region of the multiple reinforcing plates, the static stiffness of the outside rearview mirror mounting plate assembly 31 is improved, the deformation and vibration of the outside rearview mirror body 1 under the action of wind force are reduced, and thus the wind noise is reduced; by setting the distance between the overlapped region and the first installation point connecting line less than or equal to the first set threshold, the moment arm under the action of wind resistance is shortened, the rotation tendency of the outside rearview mirror body 1 is reduced, and the generation of wind noise is indirectly suppressed.

[0023] The outside rearview mirror body 1 is connected to the door sheet metal system 3 through the mounting structure 10, wherein the mounting structure 10 of the outside rearview mirror body 1 is completely arranged inside the door sheet metal system 3, the window sill outer water cut 4 is installed first, the outside rearview mirror body 1 and the window sill outer water cut 4 overlap in the X direction of the whole vehicle coordinate system and are pressed on the window sill outer water cut 4 in the Z direction of the whole vehicle coordinate system, the installation exposed surface of the outside rearview mirror body 1 is flush with the appearance of the window sill outer water cut 4, which not only ensures the coordination of the appearance, but also reduces the aerodynamic interference possibly caused by the structure protrusion, in addition, the flush design can also reduce wind resistance or rainwater accumulation and improve the aerodynamic performance.

[0024] Since the window sill outer water cut 4 is the lower boundary of the glass exposed outside the door structure, the flush design of the window sill outer water cut 4 and the installation exposed surface of the rearview mirror body not only eliminates the visual misplacement, but also makes the overall modeling of the door more smooth, while avoiding the blocking of the triangular window 2 area by the outside rearview mirror body 1, maximizing the transparent area of the triangular window 2 and significantly improving the openness of the driving field of view.

[0025] Referring to Figure 2 andFigure 1 As shown in Figure 2 And Figure 1 The installation process of the exterior mirror body 1 is shown. The outer plate in the door panel system 3 is provided with a mounting hole, and the exterior mirror body 1 is placed into the theoretical position along the vehicle coordinate system Z direction when installed, as shown in Figure 2 As shown in Figure 1

[0026] On the basis of the above embodiment, in this embodiment, the mounting structure 10 is provided with a positioning pin 100 and a bolt 101.

[0027] Specifically, as shown in Figure 4 As shown in, two cylindrical positioning pins 100 and three bolts 101 are provided on the mounting structure 10 of the exterior mirror body 1, corresponding positioning holes 3110 and through holes 3111 are provided on the door panel system 3, and the exterior mirror body 1 is placed into the theoretical position along the vehicle coordinate system Z direction and positioned by the positioning pin 100, and then tightened and fixed by the three bolts 101. It should be noted that in this embodiment, the positioning pin 100 and the bolt 101 are provided with two and three respectively, and in other embodiments, the number of positioning pins 100 and bolts 101 can be changed according to the actual situation, which is not limited in this application.

[0028] Further, the mounting structure 10 has a mounting area, and the thickness of the mounting area is greater than a third set thickness threshold, and the positioning pin 100 is located in the mounting area.

[0029] Specifically, due to the Y direction space of the mounting hole of the outer plate in the door panel system 3, the positioning pin 100 is too long to be placed into the mounting hole along the vehicle coordinate system Z direction, and the positioning pin 100 is too short to be positioned in the theoretical position when the bolt 101 is not tightened, so as to be easily pulled out and not play a positioning role. Therefore, along the vehicle coordinate system X direction, the positioning pin 100 needs to be arranged at the position of the mounting structure 10 along the vehicle coordinate system Y direction, which is the thickest position, and the thickness of this position is greater than the third set thickness threshold, corresponding to the maximum size of the outer plate through hole 3111 along the vehicle coordinate system Y direction.

[0030] On the basis of the above embodiment, in this embodiment, the door panel system 3 further comprises an inner plate 30, and the exterior mirror mounting plate assembly 31 is connected to the surface of the inner plate 30.

[0031] Among them, the inner plate 30 and the exterior mirror mounting plate assembly 31 in the door panel system 3 are connected by welding points.

[0032] ​Further, the mutually overlapped reinforcing plates include: an outside rearview mirror mounting plate body 310 connected to the surface of the inner plate 30; an outside rearview mirror patch plate 311 connected to the surface of the inner plate 30, the outside rearview mirror patch plate 311 being connected to the outside rearview mirror body 1; and an outside water cutting reinforcing plate 312 connected to the surface of the inner plate 30; wherein the outside rearview mirror mounting plate body 310, the outside rearview mirror patch plate 311, and the outside water cutting reinforcing plate 312 are mutually overlapped and form an overlapping area A (see Figure 5 The outside rearview mirror body 1 is a cantilever structure on the door panel system 3, and the layered structure significantly enhances the local rigidity of the outside rearview mirror mounting plate assembly 31, reduces the bending deformation of the cantilever structure, and maintains stability, especially under dynamic loads (such as wind resistance, collision) during vehicle driving.

[0033] Further, in this embodiment, the outside rearview mirror mounting plate body 310 is located between the outside rearview mirror patch plate 311 and the outside water cutting reinforcing plate 312, the outside rearview mirror mounting plate body 310 mainly supports the inner plate 30, the outside rearview mirror patch plate 311 serves as a structure and thickness compensation to improve static rigidity, and the outside water cutting reinforcing plate 312 extends along the vehicle coordinate system X on the inner plate 30 to improve the modal.

[0034] On the basis of the above-mentioned embodiments, in this embodiment, on the outside rearview mirror mounting plate assembly 31, the contact points of the outside rearview mirror body 1 and the outside rearview mirror mounting plate assembly 31 form a second mounting point connection line along the vehicle coordinate system X; the distance between the overlapping area and the first mounting point connection line is less than or equal to one-third of the length of the second mounting point connection line.

[0035] Specifically, in this embodiment, the contact points of the outside rearview mirror body 1 and the outside rearview mirror mounting plate assembly 31 form a first mounting point connection line along the vehicle coordinate system Z as shown in L3 in the figure. Figure 5 The contact points of the outside rearview mirror body 1 and the outside rearview mirror mounting plate assembly 31 form a second mounting point connection line along the vehicle coordinate system X as shown in L2 (X-direction mounting point span) in the figure. Figure 5

[0036] Wherein, L3 is the span of the mounting point of the outside rearview mirror body 1 along the vehicle coordinate system Z, serving as a rotation axis. In this application, a first set threshold value is set as 1 / 3L2, the overlapping area boundary is close to the L3 axis, the rotation trend under the action of external force (such as wind resistance) is reduced, the shaking of the Z-axis of the outside rearview mirror body 1 is reduced, and the dynamic stability is improved; the overlapping area close to the rotation axis can more effectively absorb vibration energy, inhibit high-frequency vibration of the outside rearview mirror body 1 during vehicle driving, and improve driving comfort; by shortening the distance between the overlapping area boundary and L3, local stress concentration caused by excessive span is avoided, and the service life of the structure is prolonged. ​

[0037] Further, the overlap region width is greater than or equal to the second mounting point connecting line length, that is, the overlap region width needs to be ≥ L2; the width of the overlap region in the X direction needs to cover the length of L2, ensuring that the stress at the mounting point is evenly distributed, avoiding partial failure or partial load due to insufficient support; a greater overlap width increases the contact area at the connection, improves the shear strength, and prevents the rearview mirror from sliding or falling under lateral load (such as crosswind); the matching relationship between the width and L2 helps the exterior rearview mirror mounting plate assembly 31 and the door panel system 3 to coordinate the modal frequency, reduce the risk of resonance, and improve the overall dynamic response performance of the structure.

[0038] Further, along the Y direction of the vehicle coordinate system, the exterior rearview mirror body 1 has a set distance L1 (such as shown in the figure) between the center of gravity and the door panel system 3, and the ratio of the second mounting point connecting line length to the set distance is greater than or equal to the second set threshold, that is, L2 / L1≥0.5, ensuring that the cantilever structure is balanced in multiple directions, avoiding bending or twisting due to unreasonable span. Figure 1

[0039] Similarly, the ratio of the first mounting point connecting line length to the set distance is greater than or equal to the third set threshold, that is, L3 / L1≥0.5, ensuring that the cantilever structure is balanced in multiple directions, avoiding bending or twisting due to unreasonable span.

[0040] On the basis of the above embodiments, in this embodiment, since the vehicle is mainly affected by the X-direction wind resistance during forward movement, the modal of the exterior rearview mirror body 1 in the X direction is particularly important, at this time, the exterior rearview mirror mounting plate assembly 31 needs 3 layers of plates to be overlapped in region A to enhance the torque balance effect and reduce the vibration of the rearview mirror.

[0041] Considering the welding process feasibility, the sum of the thicknesses of the exterior rearview mirror mounting plate body 310, the exterior rearview mirror patch plate 311, and the exterior water cutting reinforcement plate 312 is less than or equal to the first set thickness threshold, in this embodiment, the sum of the thicknesses of the exterior rearview mirror mounting plate body 310, the exterior rearview mirror patch plate 311, and the exterior water cutting reinforcement plate 312 is set to be ≤4mm, which can avoid defects such as welding thermal deformation, porosity, or cracks caused by excessive thickness, ensuring the connection strength and process stability; ​The thickness of the outer rearview mirror mounting plate body 310, the thickness of the outer rearview mirror patch plate 311 and the thickness of the outer water cutting reinforcing plate 312 are respectively a first thickness, a second thickness and a third thickness, the first thickness is less than the second thickness, and the first thickness is less than the third thickness. In this embodiment, the thinnest plate, i.e., the outer rearview mirror mounting plate body 310, is designed in the middle to make the heat distribution more uniform during welding, reduce stress concentration caused by thickness differences, and at the same time, the thicker plates on both sides provide support, form a stiffness gradient, and improve the bending and torsional resistance of the overall structure.

[0042] In this embodiment, when the second thickness is less than the third thickness, the thickness difference between the third thickness and the first thickness is less than a second set thickness threshold; when the third thickness is less than the second thickness, the thickness difference between the second thickness and the first thickness is less than the second set thickness threshold.

[0043] That is, in this embodiment, the thickness difference between the thickest plate and the thinnest plate is < 3mm, and during welding, different thicknesses of the plates are prone to stress concentration due to differences in the thermal expansion coefficient. A thickness difference of less than 3mm can reduce thermal stress and reduce the risk of deformation (such as warping and twisting) in the welding area, ensuring the connection strength of the outer rearview mirror mounting plate assembly 31 and the door panel system 3; at the same time, a large thickness difference will cause stress concentration, especially at the connection between the outer rearview mirror mounting point (L3) and the overlapping area (area A), limiting the difference to make the outer rearview mirror mounting plate body 310, the outer rearview mirror patch plate 311 and the outer water cutting reinforcing plate 312 have more uniform stress distribution when stressed, reducing the risk of local failure.

[0044] Further, in this embodiment, the A area is located behind the center of gravity of the outer rearview mirror body 1 in the X direction in the Y direction projection. When the wind resistance or external force at the center of gravity of the outer rearview mirror body 1 is applied in the X direction, the A area acts as a moment balance point, and its position close to the rear of the center of gravity can shorten the arm and reduce the tendency to rotate around the mounting point, effectively suppressing the vibration caused by wind resistance or road bumps; and optimizing the stress distribution of the structure, so that the outer rearview mirror body 1 remains stable under dynamic loads (such as crosswinds and collisions) during driving, reducing the interference of shaking with the driver's field of view; at the same time, the rear position of the A area helps to adjust the modal frequency of the mounting structure 10, avoiding resonance with the wind resistance frequency or the body vibration frequency, and reducing high-frequency noise.

[0045] In summary, the automobile outer rearview mirror mounting structure of the present application ensures that the mirror arm of the outer rearview mirror body 1 is flush with the window sill line; through a simple and reliable way, the mounting strength, modal and the like of the outer rearview mirror body 1 can meet the vehicle performance requirements; and at the same time, the transparency of the triangular window 2 is increased.

[0046] In a second aspect, the embodiments of the present application provide an automobile, which comprises the automobile outer rearview mirror mounting structure provided by any of the above embodiments of the present application.

[0047] In the present application, the exposed mounting surface of the exterior rearview mirror body 1 is flush with the outer water cut 4 of the window sill, eliminating the visual abruptness caused by edge misalignment, making the door lines smoother and the overall appearance more coordinated; the outer water cut 4 of the window sill serves as the lower boundary of the glass, and the exterior rearview mirror body 1 is flush with it to avoid blocking the transparent area of ​​the triangular window 2, enhancing the driver's rearview field of view and improving driving safety; by setting the overlapping area of ​​the multi-layer reinforcement plate, the static stiffness of the exterior rearview mirror mounting plate assembly 31 is improved, and the deformation and vibration of the exterior rearview mirror body 1 under the action of wind force are reduced, thereby reducing wind noise; by setting the distance between the overlapping area and the connecting line of the first mounting point to be less than or equal to the first set threshold, the moment arm under the action of wind resistance is shortened, the rotation tendency of the exterior rearview mirror body 1 is reduced, and the generation of wind noise is indirectly suppressed.
