Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a mounting assembly of an exterior rearview mirror, a vehicle door, and a vehicle. Background Art

[0002] With the continuous improvement of living standards, cars have become one of the most important means of transportation for people. Cars usually refer to non-track-borne vehicles that are driven by power (such as fuel, hybrid, pure electric, etc.) and have four or more wheels. Their main functions include walking, carrying people and transportation. Cars have brought convenience, comfort and safety to people's travel, and have also promoted the development of industries, accelerated economic improvement, and changed people's lifestyles.

[0003] The rearview mirror is an important part of the car. It can assist the driver to obtain external information such as the rear, side and bottom of the car, and plays a vital role in safe driving. According to the different installation positions, the rearview mirror can be divided into many types such as the exterior rearview mirror, interior rearview mirror and lower rearview mirror. Among them, the exterior rearview mirror is generally installed on the front doors on the left and right sides of the car. The driver can use the exterior rearview mirror to easily observe the environment around the car.

[0004] At present, the exterior rearview mirror in the prior art is usually installed in the triangular window area of ​​the front door (i.e., the roughly triangular area on the front door near the A-pillar) or directly fixed on the door panel of the front door. Due to the small area of ​​the triangular window area and the poor rigidity and strength of the sheet metal structure, the exterior rearview mirror is prone to shaking and abnormal noise when installed on the triangular window area, which greatly reduces the user experience. Although the overall rigidity and strength of the front door panel are good, in order to enable the driver to obtain a wider field of vision, the exterior rearview mirror is usually arranged at a position close to the water tangent line of the front door (i.e., at the upper edge of the front door panel), so that when the exterior rearview mirror is assembled at a position close to the water tangent line, the door panel is easily deformed under the action of the force arm caused by the extension of the exterior rearview mirror. In particular, in recent years, in order to give the rearview mirror more functions, its internal components have been continuously increased, resulting in the weight of the rearview mirror becoming heavier and heavier. Therefore, even if the exterior rearview mirror is fixed on the front door panel, the exterior rearview mirror still has the risk of shaking and abnormal noise.

[0005] This field requires a new technical solution to solve the above problems. Summary of the invention

[0006] In order to solve the above-mentioned problems in the prior art, that is, to solve the technical problems in the prior art that the exterior rearview mirror is prone to shaking and abnormal noise, the present invention provides an installation assembly for the exterior rearview mirror. The installation assembly includes: a door inner panel, the door inner panel having a water tangent line extending along its longitudinal direction; a hinge reinforcement plate, the hinge reinforcement plate being fixed to the door inner panel, and a predetermined installation area suitable for fixing the exterior rearview mirror is formed on the hinge reinforcement plate; an outer waistline reinforcement plate, the outer waistline reinforcement plate being fixed to the door inner panel and located below the water tangent line; and a reinforcement member, the reinforcement member is fixedly connected to the hinge reinforcement plate and the outer waistline reinforcement plate respectively, so that the stress generated by fixing the exterior rearview mirror can be transmitted to the bottom of the water tangent line through the reinforcement member.

[0007] In the installation assembly of the exterior rearview mirror of the present invention, it includes a door inner panel, a hinge reinforcement plate, an outer waistline reinforcement plate, and a reinforcement member. The door inner panel has a water tangent line extending along its longitudinal direction. The hinge reinforcement plate is fixed to the door inner panel. A predetermined installation area suitable for fixing the exterior rearview mirror is formed on the hinge reinforcement plate (that is, the exterior rearview mirror can be fixed on the hinge reinforcement plate). The outer waistline reinforcement plate is fixed to the door inner panel and is located below the water tangent line. The reinforcement member is fixedly connected to the hinge reinforcement plate and the outer waistline reinforcement plate respectively, so that the stress generated by fixing the exterior rearview mirror can be transmitted to the bottom of the water tangent line through the reinforcement member. By providing a reinforcement member, and by forming a fixed connection between the reinforcement member and the hinge reinforcement plate and the outer waistline reinforcement plate respectively, the installation assembly of the exterior rearview mirror of the present invention can transmit the stress generated when the exterior rearview mirror is fixed on the hinge reinforcement plate from the hinge reinforcement plate to the reinforcement member vertically downward, and transmit it to the outer waistline reinforcement plate through the reinforcement member, so that the stress originally concentrated on the hinge reinforcement plate can be evenly dispersed to the outer waistline reinforcement plate and other components, thereby reducing the stress on the hinge reinforcement plate. Therefore, the exterior rearview mirror can be more firmly fixed on the hinge reinforcement plate, effectively reducing the possibility of shaking and abnormal noise, and improving the user experience. Furthermore, since the stress generated by fixing the exterior rearview mirror can be transmitted to the bottom of the water tangent line through the reinforcement member, rather than being concentrated at a position close to the water tangent line, the rigidity and strength of the entire installation assembly can be enhanced, and the service life can be extended. Accordingly, under the condition of meeting the rigidity and strength, the material of the processing installation assembly can also be appropriately reduced, thereby reducing the manufacturing cost. In addition, since the installation assembly of the exterior rearview mirror of the present invention improves the rigidity and strength of the predetermined installation area by adding a separate reinforcement without changing the structure of components such as the door inner panel, hinge reinforcement plate and outer waistline reinforcement plate, the adaptability of the installation assembly of the exterior rearview mirror of the present invention is also significantly improved.

[0008] In the preferred technical solution of the installation assembly of the exterior rearview mirror, the installation assembly further includes a window guide rail, which extends vertically along the door inner panel to below the water tangent line and is fixedly connected to the hinge reinforcement plate and the reinforcement member. By configuring the vertically extending window guide rail to be fixedly connected to the hinge reinforcement plate and the reinforcement member, the stress generated by fixing the exterior rearview mirror can also be vertically transmitted downward from the window guide rail to the reinforcement member, thereby increasing the path of stress transmission and enhancing the effect of stress dispersion.

[0009] In the preferred technical solution of the installation assembly of the exterior rearview mirror, the hinge reinforcement plate, the window guide rail, and the outer waistline reinforcement plate are sequentially spaced apart along the thickness direction of the door inner panel. Through the above arrangement, the stress generated by fixing the exterior rearview mirror can also be transmitted in a direction transverse to the door inner panel (i.e., the thickness direction of the door inner panel) and transferred and dispersed to the outer waistline reinforcement plate, thereby further dissipating the stress.

[0010] In the preferred technical solution of the installation assembly of the exterior rearview mirror, the reinforcement is a curved plate-like structure, which has a first fixed section that abuts against the hinge reinforcement plate, a second fixed section that abuts against the window guide rail, and a third fixed section that abuts against the outer waistline reinforcement plate. Through the above configuration, the reinforcement can have a relatively simple structure and be easy to process. In addition, the curved plate-like structure can not only make it easier to avoid features during structural design, but also increase its own rigidity and strength.

[0011] In the preferred technical solution of the above-mentioned installation assembly of the exterior rearview mirror, the first fixing section is fixed to the hinge reinforcement plate and the door inner panel by three-layer plate spot welding, the second fixing section is fixed to the window guide rail by two-layer plate spot welding, and the third fixing section is fixed to the outer waistline reinforcement plate by two-layer plate spot welding. Through the above-mentioned arrangement, the reinforcement member can be firmly fixedly connected to the hinge reinforcement plate, the door inner panel, the window guide rail, the outer waistline reinforcement plate and other components, so that the installation assembly of the exterior rearview mirror has a stable and firm structure.

[0012] In the preferred technical solution of the mounting assembly of the exterior rearview mirror, a plurality of rearview mirror mounting holes spaced apart from each other are formed in the predetermined mounting area. The plurality of rearview mirror mounting holes spaced apart from each other are provided in the predetermined mounting area, so that the exterior rearview mirror can be conveniently mounted.

[0013] In the preferred technical solution of the above-mentioned installation assembly of the exterior rearview mirror, each of the rearview mirror installation holes is located above the outer waistline reinforcement plate. Each rearview mirror installation hole is arranged above the outer waistline reinforcement plate, so that the rearview mirror can be easily assembled into the predetermined installation area, preventing the outer waistline reinforcement plate and other components from affecting the assembly of the rearview mirror, thereby improving the assembly efficiency.

[0014] In the preferred technical solution of the mounting assembly of the exterior rearview mirror, at least one first reinforcement protrusion protruding in a direction away from the hinge reinforcement plate and spaced from each other is formed on the door inner panel, and at least one second reinforcement protrusion opposite to and protruding in the opposite direction of each first reinforcement protrusion is formed on the hinge reinforcement plate, so that each first reinforcement protrusion and the corresponding second reinforcement protrusion enclose a reinforcement cavity. Through the above arrangement, the rigidity and strength of the door inner panel and the hinge reinforcement plate can be improved.

[0015] In the preferred technical solution of the above-mentioned installation assembly of the exterior rearview mirror, the reinforcement cavity is configured to extend vertically and pass through the extension line of the water tangent line. The reinforcement cavity extends vertically and passes through the extension line of the water tangent line, which can further enhance the rigidity and strength of the door inner panel and the hinge reinforcement plate and extend their service life.

[0016] In order to solve the above-mentioned problems in the prior art, that is, to solve the technical problems in the prior art that the exterior rearview mirror is prone to shaking and making abnormal noises, the present invention also provides a vehicle door. The vehicle door comprises: an exterior rearview mirror; and an exterior rearview mirror installation assembly according to any one of the above items, and the exterior rearview mirror is installed in a predetermined installation area of ​​the exterior rearview mirror installation assembly. By adopting the exterior rearview mirror installation assembly described in any one of the above items, the vehicle door of the present invention can disperse the stress generated by fixing the exterior rearview mirror to below the water tangent line, thereby effectively preventing the exterior rearview mirror from shaking and making abnormal noises during vehicle use after installation.

[0017] In order to solve the above-mentioned problem in the prior art, that is, to solve the technical problem that the exterior rearview mirror is prone to shaking and making abnormal noise in the prior art, the present invention further provides a vehicle. The vehicle includes the vehicle door described above. By adopting the vehicle door of the present invention, the vehicle of the present invention can effectively prevent the exterior rearview mirror from shaking and making abnormal noise after installation (especially when the vehicle is driving at high speed), thereby improving the driving experience of the user.

Alternatively, the vehicle 1 may also be an MPV (i.e., multi-purpose vehicle), an SUV (i.e., off-road vehicle) or other suitable vehicles. The vehicle 1 may be a fuel sedan, a hybrid sedan or a pure electric sedan.

[0063] like Figure 1As shown, the vehicle 1 has a door 10. In one or more embodiments, the door 10 includes a front door 101 located at the front of the vehicle body and a rear door 102 located at the rear of the vehicle body. Among them, the front door 101 includes two front doors 101 arranged on the left and right sides of the vehicle body and opposite to each other, and the rear door 102 includes two rear doors 102 arranged on the left and right sides of the vehicle body and opposite to each other. Alternatively, the door 10 may also include only the front door 101. In one or more embodiments, the front door 101 is a frameless door (i.e., without a window frame). Alternatively, the front door 101 may also be a framed door (i.e., with a window frame). The front door 101 has a door panel 1012 and a triangular window area 1011 formed above the door panel 1012 and close to the A-pillar of the vehicle 1. The door panel 1012 is provided with an external water-cut structure 10121 extending roughly in its longitudinal direction, so that impurities such as water droplets, water mist and dust on the outer surface of the window glass 1013 can be cut off during the lifting process, while also having an aesthetic effect.

[0064] Continue to see Figure 1 An exterior rearview mirror 20 is provided on each front door 101, and a mounting assembly 30 (see Figure 2 ). In one or more embodiments, the exterior rearview mirror 20 is installed in the triangular window area 1011.

[0065] In one or more embodiments, the exterior rearview mirror 20 has a manual adjustment function. Alternatively, the exterior rearview mirror 20 may also have one or more functions of automatic adjustment, electric folding, rearview mirror heating, and automatic downward folding when reversing to improve the user experience.

[0066] The following is based on Figure 2-Figure 7 An embodiment of the mounting assembly 30 of the exterior rearview mirror 20 of the present invention is described in detail.

[0067] Figure 2 is a structural schematic diagram of an embodiment of a mounting assembly of an exterior rearview mirror of the present invention; Figure 3 is an exploded view of an embodiment of a mounting assembly of an exterior rearview mirror of the present invention; Figure 4a is a front view of an embodiment of the mounting assembly of the exterior rearview mirror of the present invention, viewed from the outside to the inside; Figure 4b FIG. 2 is a front view of an embodiment of the mounting assembly of the exterior rearview mirror of the present invention, viewed from the inside out. Figure 2-4b As shown, in one or more embodiments, the mounting assembly 30 of the present invention includes components such as a door inner panel 31 , a hinge reinforcement plate 32 , a window guide track 33 , an outer waistline reinforcement plate 34 , and a reinforcement member 35 .

[0068] Continue to see Figure 2-4bIn one or more embodiments, the door inner panel 31 is made of galvanized steel sheet or other suitable metal material through a rolling process. The door inner panel 31 has a water cut line 311 extending roughly along its longitudinal direction. An inner water cut structure (not shown in the figure) is provided at the position of the water cut line 311, so that the impurities such as water droplets, water mist and dust on the inner surface of the window glass 1013 can be cut off during the lifting process, and it can also play a role in aesthetics. The door inner panel 31 is formed on the inner side of the door panel 1012. In the case where the front door 101 is a framed door (i.e., with a window frame), the door inner panel 31 can be stamped and formed integrally with the window frame of the front door 101. Alternatively, the window frame of the front door 101 can also be manufactured separately from the door inner panel 31, and then connected by welding or screws.

[0069] Continue to see Figure 2-4b In one or more embodiments, the hinge reinforcement plate 32 is made of galvanized steel plate or other suitable metal materials through a stamping process. The hinge reinforcement plate 32 is fixed to the upper part of the door inner panel 31. Preferably, the hinge reinforcement plate 32 is fixedly connected to the door inner panel 31 by a resistance spot welding (i.e., Resistance Spot Welding) process, so that a firm and stable fixed connection is formed between the hinge reinforcement plate 32 and the door inner panel 31. Alternatively, the hinge reinforcement plate 32 can also be fixed to the door inner panel 31 by other suitable means, such as screw fixing. A predetermined installation area 321 for fixing the exterior rearview mirror 20 is provided on the hinge reinforcement plate 32, and the predetermined installation area 321 is close to the water tangent line 311. In one or more embodiments, the predetermined installation area 321 is located at a position of the hinge reinforcement plate 32 close to the triangular window area 1011 of the front door 101.

[0070] In one or more embodiments, three rearview mirror mounting holes spaced apart from each other are provided in the predetermined mounting area 321. The three rearview mirror mounting holes are respectively a first rearview mirror mounting hole 3211, a second rearview mirror mounting hole 3212, and a third rearview mirror mounting hole 3213. The first rearview mirror mounting hole 3211 and the third rearview mirror mounting hole 3213 are both located above the outer waistline reinforcement plate 34, while the second rearview mirror mounting hole 3212 is located below the upper edge of the outer waistline reinforcement plate 34 and away from the triangular window area 1011 with weaker strength, so that stronger static stiffness can be obtained. The first rearview mirror mounting hole 3211, the second rearview mirror mounting hole 3212, and the third rearview mirror mounting hole 3213 are arranged in a substantially triangular shape so as to firmly fix the outer rearview mirror 20. In an alternative embodiment, three rearview mirror mounting holes spaced apart from each other are also provided in the predetermined mounting area 321. The three rearview mirror mounting holes are respectively the first rearview mirror mounting hole 3211, the third rearview mirror mounting hole 3213, and the fourth rearview mirror mounting hole 3214. The first rearview mirror mounting hole 3211, the third rearview mirror mounting hole 3213, and the fourth rearview mirror mounting hole 3214 are all arranged above the outer waistline reinforcement plate 34, so that when assembling the outer rearview mirror 20, it can be conveniently assembled to the corresponding rearview mirror mounting hole without being blocked by the outer waistline reinforcement plate 34, the door outer panel and other components, thereby improving the assembly efficiency (it should be pointed out that the heights of the door outer panel and the outer waistline reinforcement plate 34 in the vertical direction are approximately the same). In addition, the first rearview mirror mounting hole 3211, the third rearview mirror mounting hole 3213, and the fourth rearview mirror mounting hole 3214 are also arranged in a roughly triangular shape to firmly fix the outer rearview mirror 20. In another alternative embodiment, the number of rearview mirror mounting holes is set to 4, including a first rearview mirror mounting hole 3211, a second rearview mirror mounting hole 3212, a third rearview mirror mounting hole 3213, and a fourth rearview mirror mounting hole 3214, so that the stress generated by fixing the exterior rearview mirror 20 can be dispersed more evenly to ensure the tightness of the exterior rearview mirror 20.

[0071] It should be pointed out that mounting holes are provided on the door inner panel 31, which are opposite to and aligned with each rearview mirror mounting hole, so that the exterior rearview mirror 20 can be fixed to the sheet metal structure formed by connecting the door inner panel 31 and the hinge reinforcement plate 32 through a mounting part (not shown in the figure) to obtain a more firm and stable fixed connection.

[0072] Continue to see Figure 2-4bIn one or more embodiments, the window rail 33 is configured to be made of galvanized steel plate or other suitable metal materials through a stamping process. A lifting groove 331 is formed on the window rail 33 to allow the window glass 1013 to be lifted and lowered vertically, so that the user can conveniently adjust the lifting and lowering of the window glass 1013 according to actual needs. The window rail 33 extends roughly vertically to the bottom of the water tangent line 311 and forms a fixed connection with the hinge reinforcement plate 32. Preferably, the window rail 33 is configured to form a fixed connection with the hinge reinforcement plate 32 and the door inner panel 31 through a three-layer plate spot welding method to obtain a firm and stable connection. In one or more embodiments, the lower end of the window rail 33 (not shown in the figure) is fixed on the stopper reinforcement plate (not shown in the figure), and the stopper reinforcement plate is configured to be fixed on the door inner panel 31, so that a more firm and stable connection is formed between the window rail 33 and the door inner panel 31.

[0073] Continue to see Figure 2-4b In one or more embodiments, the outer waistline reinforcement plate 34 is made of galvanized steel plate or other suitable metal materials through a stamping process. The outer waistline reinforcement plate 34 extends approximately in the longitudinal direction and is located below the water tangent line 311 to support and strengthen the sheet metal structure. In one or more embodiments, the outer waistline reinforcement plate 34 is fixed to the two longitudinal ends of the door inner panel 31 by a resistance spot welding process. Alternatively, the outer waistline reinforcement plate 34 can also be fixed to the door inner panel 31 by other means, such as by screw fixing.

[0074] Figure 5 The embodiment of the installation assembly of the exterior rearview mirror of the present invention is along Figure 4a The cross-sectional view obtained by the AA section line shown; Figure 7 FIG. 2 is a schematic structural diagram of an embodiment of a reinforcement member in the installation assembly of an exterior rearview mirror of the present invention. Figure 5 and Figure 7 As shown, in one or more embodiments, the reinforcement 35 is made of galvanized steel plate or other suitable metal materials through mechanical processing. The reinforcement 35 is configured as a curved plate-like structure. Specifically, the curved plate-like structure has a first fixed section 351 that abuts against the hinge reinforcement plate 32, a second fixed section 352 that abuts against the window guide 33, and a third fixed section 353 that abuts against the outer waistline reinforcement plate 34. The first fixed section 351 and the second fixed section 352 are connected by an arc-shaped connecting section 354. The curved plate-like structure can not only make the reinforcement 35 have a relatively simple structure to simplify the manufacturing process and reduce the manufacturing cost, but also make it easier to avoid features during structural design, and at the same time increase the rigidity and strength of the reinforcement 35 itself.

[0075] like Figure 5As shown, in one or more embodiments, the first fixed section 351 is fixedly connected with the hinge reinforcement plate 32 and the door inner panel 31 by three-layer plate spot welding, the second fixed section 352 is fixedly connected with the window guide rail 33 by two-layer plate spot welding, and the third fixed section 353 is fixedly connected with the outer waistline reinforcement plate 34 by two-layer plate spot welding. Through the above arrangement, the reinforcement member 35 can be firmly fixedly connected with the hinge reinforcement plate 32, the door inner panel 31, the window guide rail 33 and the outer waistline reinforcement plate 34, so that the installation assembly 30 has a stable structure.

[0076] Continue to see Figure 5 In one or more embodiments, the hinge reinforcement plate 32, the window guide rail 33, and the outer waistline reinforcement plate 34 are sequentially spaced apart along the thickness direction of the door inner panel 31 (i.e., transverse to the door inner panel 31). By configuring the hinge reinforcement plate 32, the window guide rail 33, and the outer waistline reinforcement plate 34 to be sequentially spaced apart along the transverse direction, the stress generated by the fixed exterior rearview mirror 20 can be transmitted not only vertically to the lower side of the water tangent line 311, but also transversely, so that the stress can be more evenly dispersed, thereby improving the rigidity and strength of the mounting assembly 30.

[0077] Figure 6 The embodiment of the installation assembly of the exterior rearview mirror of the present invention is along Figure 4a The cross-sectional view is obtained by the BB section line shown. Figure 6As shown, in one or more embodiments, at least one first reinforcement protrusion 312 is formed on the door inner panel 31, which protrudes in a direction away from the hinge reinforcement plate 32 and is spaced from each other, so as to enhance the rigidity and strength of the door inner panel 31. The number of the first reinforcement protrusions 312 can be 2, or other suitable numbers more or less than 2, such as 1, 3, etc. In one or more embodiments, at least one second reinforcement protrusion 322 is formed on the hinge reinforcement plate 32, which is opposite to and protrudes in the opposite direction from each first reinforcement protrusion 312, so that each first reinforcement protrusion 312 and the corresponding second reinforcement protrusion 322 enclose a reinforcement cavity. In one or more embodiments, the reinforcement cavity includes a first reinforcement cavity 323a and a second reinforcement cavity 323b spaced from each other. In one or more embodiments, the first reinforcement cavity 323a and the second reinforcement cavity 323b are configured to extend approximately in the vertical direction and pass through the extension line of the water tangent line 311, that is, the first reinforcement cavity 323a and the second reinforcement cavity 323b intersect with the extension line of the water tangent line 311 in the vertical direction, so as to further improve the rigidity and strength of the door inner panel 31 and the hinge reinforcement plate 32, and extend their service life. In one or more embodiments, the first reinforcement cavity 323a and the second reinforcement cavity 323b in the vertical center extension direction and the water tangent line 311 form an angle range of greater than or equal to 10°. Further, the first reinforcement cavity 323a and the second reinforcement cavity 323b in the vertical center extension direction and the water tangent line 311 form an angle range of greater than or equal to 15°. Further, the first reinforcement cavity 323a and the second reinforcement cavity 323b in the vertical center extension direction and the water tangent line 311 form an angle range of 30°-120°. In one or more embodiments, the first reinforcement cavity 323a has a first length L1 and a first width W1; the second reinforcement cavity 323b has a second length L2 and a second width W2. Within the allowed range of size, the first length L1 and the first width W1, as well as the second length L2 and the second width W2 are made as large as possible, and a smooth transition is formed between the various parts of each reinforcement cavity to prevent stress concentration.

[0078] In one or more embodiments, the mounting assembly 30 of the present invention only includes components such as a door inner panel 31, a hinge reinforcement plate 32, an outer waistline reinforcement plate 34, and a reinforcement member 35, that is, it does not include a window guide rail 33. The door inner panel 31 has a water tangent line 311 extending in the longitudinal direction. The hinge reinforcement plate 32 is fixed to the door inner panel 31. A predetermined mounting area 321 for fixing the exterior rearview mirror 20 is formed on the hinge reinforcement plate 32. The outer waistline reinforcement plate 34 is fixed to the door inner panel 31 and is located below the water tangent line 311. The reinforcement member 35 is fixedly connected to the hinge reinforcement plate 32 and the outer waistline reinforcement plate 34, respectively, so that the stress generated by fixing the exterior rearview mirror 20 can be transmitted to the bottom of the water tangent line 311 through the reinforcement member 35. It should be pointed out that the parts not described in this embodiment can be configured the same as any of the above embodiments, and will not be repeated here.

[0079] In order to verify the influence of the mounting assembly 30 of the exterior rearview mirror 20 of the present invention on the whole vehicle mode and the static stiffness of the rearview mirror mounting hole, the present invention selected one of the embodiments and conducted a comparative experiment with the mounting assembly in the prior art. Among them, the mounting assembly 30 of the present invention includes components such as the door inner panel 31, the hinge reinforcement plate 32, the window guide 33, the outer waistline reinforcement plate 34, and the reinforcement 35, and a first reinforcement cavity 323a and a second reinforcement cavity 323b are formed on the door inner panel 31 and the hinge reinforcement plate 32. The comparison mounting assembly does not include the reinforcement 35, and the comparison mounting assembly does not include the first reinforcement cavity 323a and the second reinforcement cavity 323b (that is, the door inner panel 31 does not include the first reinforcement protrusion 312, and the hinge reinforcement plate 32 does not include the second reinforcement protrusion 322). In addition, in order to verify the influence of the arrangement position on the static stiffness of the rearview mirror mounting hole, the mounting assembly 30 of the present invention is provided with four rearview mirror mounting holes, namely, the first rearview mirror mounting hole 3211, the second rearview mirror mounting hole 3212, the third rearview mirror mounting hole 3213, and the fourth rearview mirror mounting hole 3214, while the comparative mounting assembly only includes three rearview mirror mounting holes, which are arranged at the same positions as the first rearview mirror mounting hole 3211, the second rearview mirror mounting hole 3212, and the third rearview mirror mounting hole 3213. Except for the above differences, the other components of the mounting assembly 30 of the present invention and the comparative mounting assembly are configured in the same manner, and the test conditions are also the same.

[0080] It should be pointed out that "mode" is the natural vibration characteristic of the structural system. Each mode has specific modal parameters such as natural frequency, damping ratio and modal vibration shape. These modal parameters can be obtained by calculation or experimental analysis. "Static stiffness" is the ability of the structure to resist deformation under specific static excitation. It is generally measured by the degree of deformation of the structure under static load, and its value can be obtained through experiments.

[0081] Table 1 Comparative test results of mechanical properties of exterior rearview mirror installation assembly

[0082]

[0083] As can be seen from Table 1, by adopting the mounting assembly 30 of the exterior rearview mirror 20 of the present invention, the vehicle modality of the vehicle 1 of the present invention is improved by 9.25%, making the structure of the vehicle more stable. In addition, the static stiffness of the first rearview mirror mounting hole, the second rearview mirror mounting hole, and the third rearview mirror mounting hole are all improved to varying degrees, and the increase is relatively large (the minimum increase is 37.26%, and the maximum increase is 85.23%).

[0084] Continuing to refer to Table 1, the static stiffness of the fourth rearview mirror mounting hole 3214 is 249N / mm, which is greater than the static stiffness of each rearview mirror mounting hole in the comparative mounting assembly. Therefore, in one or more embodiments, when the mounting assembly 30 of the present invention includes the first rearview mirror mounting hole, the third rearview mirror mounting hole, and the fourth rearview mirror mounting hole, it can not only meet the rigidity and strength requirements, so that the exterior rearview mirror 20 is firmly fixed on the rearview mirror mounting hole, but also each rearview mirror mounting hole can be arranged above the outer waistline reinforcement plate 34 to avoid the outer waistline reinforcement plate 34 and other components, thereby improving assembly efficiency.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
