[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are in contact indirectly through an intermediate medium. Moreover, a first feature being “above”, “above”, or “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0029] The rigidity of the rearview mirror mounting point greatly affects the overall installation performance of the rearview mirror, which is directly related to the structure and welding form of the rearview mirror mounting bracket. At present, the rearview mirror mounting bracket is often welded to the plane on the outer window edge reinforcement plate, and then welded to the door outer panel through the outer window edge reinforcement plate, wherein the outer window edge reinforcement plate and the door outer panel are supported by a Z-shaped bracket.

[0030] In the related art, if the rigidity of the rearview mirror mounting point is to be improved, it is mainly achieved by increasing the material thickness or size of the rearview mirror mounting bracket. This will easily lead to an increase in the overall weight, which is not conducive to the lightweight of the vehicle. In addition, the number of parts of the entire rearview mirror mounting structure is large, and the control difficulty in the production process is increased, thereby greatly reducing the qualification rate of the overall structure.

[0031] See also Figure 1-Figure 5 In order to solve the problems of the existing rearview mirror installation structure having many parts, heavy weight and low qualified rate, the present application provides a door rearview mirror installation structure 100. The door rearview mirror installation structure 100 includes a door inner panel 10, an outer window edge reinforcement plate 20 and a rearview mirror installation plate 30. The outer window edge reinforcement plate 20 is connected to the door inner panel 10 and forms an installation gap 101 with the door inner panel 10. The rearview mirror installation plate 30 is arranged in the installation gap 101.

[0032] That is, the present application installs the rearview mirror mounting plate 30 in the installation gap 101 between the door inner plate 10 and the outer window edge reinforcement plate 20, and relies on the structure of the rearview mirror mounting plate 30 itself to achieve connection and support, replacing the Z-shaped bracket used for support in the traditional structure, thereby effectively reducing the number of parts and achieving lightweight. In addition, the reduction of parts reduces the difficulty of mutual coordination between parts, thereby greatly reducing the difficulty of control in the production process, which is conducive to improving the qualified rate of the rearview mirror mounting structure.

[0033] It should be noted that the door inner panel 10 is the largest main frame on the inner side of the door. The outer window edge reinforcement plate 20 is a reinforcement plate extending along the length direction of the vehicle body inside the door sheet metal. It is usually set in the lower edge area of ​​the door handle and the door glass to strengthen the Y-direction rigidity of the outer water shear and support the upper area of ​​the door outer panel. The rearview mirror mounting plate 30 is used to install the rearview mirror and can usually be set as a sheet metal structure.

[0034] Specifically, the rearview mirror mounting plate 30 provided by the present application includes a main body 31, a first side portion 32, a second side portion 33, a third side portion 34 and a fourth side portion 35, and a portion of the main body 31 is attached to and connected to the outer window edge reinforcement plate 20. The first side portion 32 and the second side portion 33 are respectively connected to opposite ends of the main body 31 along a first preset direction, and are arranged at an angle with the main body 31, and the ends of the first side portion 32 and the second side portion 33 away from the main body 31 are both connected to the door inner panel 10, so that the door inner panel 10, the first side portion 32, the main body 31 and the second side portion 33 can enclose a first reinforcement cavity 301. The third side portion 34 and the fourth side portion 35 are respectively connected to the opposite ends of the main body portion 31 along the second preset direction, and the third side portion 34 and the fourth side portion 35 are at least partially attached to and connected to the outer window edge reinforcement plate 20, and the third side portion 34, the main body portion 31 and the outer window edge reinforcement plate 20 form a second reinforcement cavity 302, and the fourth side portion 35, the main body portion 31 and the outer window edge reinforcement plate 20 form a third reinforcement cavity 303. The first preset direction is set at an angle to the second preset direction.

[0035] It can be understood that the rearview mirror mounting plate 30 of the present application is a four-way extending structure with small size and light weight. Among them, the first side portion 32 and the second side portion 33 of the rearview mirror mounting plate 30 are used to connect with the door inner panel 10, and form a first reinforcement cavity 301 with the door inner panel 10. The first reinforcement cavity 301 effectively improves the support strength of the rearview mirror mounting plate 30 to the door inner panel 10 and the outer window edge reinforcement plate 20. Further, the third side portion 34 and the fourth side portion 35 are used to connect with the outer window edge reinforcement plate 20, and form a second reinforcement cavity 302 and a third reinforcement cavity 303 with the outer window edge reinforcement plate 20, so as to further achieve structural reinforcement by using the second reinforcement cavity 302 and the third reinforcement cavity 303. In this way, the rearview mirror mounting plate 30 can simultaneously leverage the door inner panel 10 and the outer window edge reinforcement plate 20 through its four-way extension structure, thereby greatly improving the installation rigidity of the rearview mirror mounting point and avoiding quality defects such as shaking and abnormal noise generated by the rearview mirror when the door is closed.

[0036] In one embodiment, the first preset direction is perpendicular to the second preset direction. Thus, the first side portion 32 , the second side portion 33 , the third side portion 34 and the fourth side portion 35 are arranged in a cross shape, which is simpler to set and can improve the force stability of the rearview mirror mounting plate 30 .

[0037] To further enhance the structural strength of the rearview mirror mounting plate 30 , in one embodiment, the main body 31 , the first side portion 32 , the second side portion 33 , the third side portion 34 and the fourth side portion 35 may be configured as an integrally formed structure.

[0038] In one embodiment, if Figure 2 As shown, the main body 31 includes a main board 311 and a mounting boss 312. The mounting boss 312 protrudes from the surface of the main board 311 and is connected to the main board 311. The surface of the mounting boss 312 is attached to and connected to the outer window edge reinforcement plate 20. The second reinforcement cavity 302 and the third reinforcement cavity 303 are respectively arranged on both sides of the mounting boss 312 along the second preset direction.

[0039] By providing the mounting boss 312 on the main body 31 , the difficulty of molding the second reinforcement cavity 302 and the third reinforcement cavity 303 can be reduced by utilizing the height difference formed between the mounting boss 312 and the main board 311 .

[0040] Furthermore, in one embodiment, a mounting hole 304 is provided on the mounting boss 312, and a matching hole 201 corresponding to the mounting hole 304 is provided on the outer window edge reinforcement plate 20. A fastener is provided through and connected to the mounting hole 304 and the matching hole 201, and the fastener is used to connect the rearview mirror. In this way, the installation of the rearview mirror is facilitated, and the installation strength and stability of the rearview mirror can be improved.

[0041] In one embodiment, if Figure 2-Figure 4As shown, the third side portion 34 includes a third connecting segment 341 and a third fixing segment 342, one end of the third connecting segment 341 is connected to the main board 311, and the other end extends toward the outer window edge reinforcement plate 20 and is connected to the third fixing segment 342. The third fixing segment 342 is attached to and connected to the outer window edge reinforcement plate 20, and the third connecting segment 341, the main board 311, the side wall of the mounting boss 312 and the outer window edge reinforcement plate 20 are surrounded to form a second reinforcement cavity 302.

[0042] In this way, the third fixing section 342 can increase the contact area between the third side portion 34 and the outer window edge reinforcement plate 20, thereby improving the connection strength between the two. The third connecting section 341 and the side walls of the main board 311 and the mounting boss 312 can form a U-shaped structure, and when it is connected to the outer window edge reinforcement plate 20, it can enclose the second reinforcement cavity 302 with the outer window edge reinforcement plate 20, thereby greatly reducing the difficulty of forming the second reinforcement cavity 302.

[0043] Further, in one embodiment, if Figure 2 As shown, the main board 311 is provided with a first reinforcing rib 313, one end of the first reinforcing rib 313 extends to the connection between the main board 311 and the mounting boss 312, and the other end extends to the connection between the main board 311 and the third connecting section 341. In this way, the structural strength of the rearview mirror mounting plate 30 can be improved.

[0044] In one embodiment, if Figure 2-Figure 4 As shown, the fourth side portion 35 is connected to the side wall of the mounting boss 312 away from the outer window edge reinforcement plate 20. The outer window edge reinforcement plate 20 is formed with a step section 21, and the step section 21, the side wall of the mounting boss 312 and the fourth side portion 35 are surrounded to form a third reinforcement cavity 303.

[0045] By connecting the fourth side portion 35 to the side wall of the mounting boss 312 away from the end of the outer window edge reinforcement plate 20, a height difference can be formed between the fourth side portion 35 and the mounting boss 312, thereby forming a similar step-like structure. At the same time, a step section 21 is also provided on the outer window edge, and the two step structures are staggered, so that the third reinforcement cavity 303 can be formed between the two, thus greatly reducing the difficulty of forming the third reinforcement cavity 303.

[0046] In one embodiment, if Figure 2 , Figure 3 and Figure 5 As shown, the first side portion 32 includes a first connecting section 321 and a first fixing section 322. One end of the first connecting section 321 is connected to the main body 31, and the other end is connected to the first fixing section 322. The first fixing section 322 is attached to and connected to the door inner panel 10. The provision of the first fixing section 322 can increase the contact area between the first side portion 32 and the outer window edge reinforcement plate 20, thereby improving the connection strength between the two.

[0047] In order to improve the structural strength of the first side portion 32 , a reinforcing rib structure may be provided on the first connecting section 321 .

[0048] In one embodiment, if Figure 2 , Figure 3 and Figure 5 As shown, the second side portion 33 includes a second connecting segment 331 and a second fixing segment 332, one end of the second connecting segment 331 is connected to the main body 31, and the other end is connected to the second fixing segment 332, wherein the second fixing segment 332 is attached to and connected to the door inner panel 10. The provision of the second fixing segment 332 can increase the contact area between the second side portion 33 and the outer window edge reinforcement plate 20, thereby improving the connection strength between the two.

[0049] In order to improve the structural strength of the second side portion 33 , a reinforcing rib structure may be provided on the second connecting section 331 .

[0050] Furthermore, the main body 31 can enclose a first reinforcement cavity 301 of an annular structure with the door inner panel 10 through the first connecting section 321 and the second connecting section 331 , thereby better playing a supporting role.

[0051] Specifically, the rearview mirror mounting plate 30 is fixed to the door inner panel 10 and the outer window edge reinforcement plate 20 by welding. That is, the main body 31, the third fixing section 342 and the fourth side section 35 are fixed to the outer window edge reinforcement plate 20 by welding, and the first fixing section 322 and the second fixing section 332 are fixed to the door inner panel 10 by welding.

[0052] The present application also provides a vehicle, which includes the door rearview mirror mounting structure 100 of any one of the above embodiments.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
