Description

Technical Field

[0001] This invention relates to the field of automotive door structure technology, specifically to an installation structure between the front door window frame and the exterior rearview mirror of an automobile. Background Technology

[0002] With the release of regulations for electronic exterior rearview mirrors and the trend of automotive intelligence, the application of electronic exterior rearview mirrors is becoming increasingly widespread. Compared with traditional exterior rearview mirrors, electronic exterior rearview mirrors are smaller and lighter, requiring less space for installation and placing lower demands on the strength and rigidity of the door mounting structure. However, electronic exterior rearview mirrors are also more expensive than traditional ones. Considering overall vehicle cost during vehicle development, high-end electronic exterior rearview mirrors are typically used, while low-end traditional exterior rearview mirrors are preferred.

[0003] In existing technologies, when installing traditional exterior rearview mirrors, the current installation structure between the car's front door window frame and the exterior rearview mirror typically involves arranging three mounting points on the upper corner of the front door for installation. Since traditional exterior rearview mirrors are generally larger and heavier than electronic ones, a larger installation spacing is usually required between the three mounting points to ensure sufficient connection strength between the traditional exterior rearview mirror and the upper corner of the front door. This results in a larger gap between the three mounting points on the upper corner of the front door and the mirror. The large triangular area of ​​the rearview mirror necessitates a larger size for both the door-side mounting structure and the upper front door corner plate that accompanies it. In contrast, electronic rearview mirrors are smaller and lighter than traditional ones, allowing the door-side mounting structure to be designed to be smaller. This, in turn, enables the upper front door corner plate that accompanies the electronic rearview mirror to be designed to be smaller within the existing installation structure between the front door window frame and the rearview mirror.

[0004] However, the aforementioned situation also makes it difficult for the existing installation structure between the front door window frame and the exterior rearview mirror to be compatible with both traditional and electronic exterior rearview mirrors. This means that when the type of exterior rearview mirror needs to be changed, if the installation structure between the front door window frame and the exterior rearview mirror is also modified accordingly, the door sheet metal, being welded, cannot be adjusted. Therefore, two sets of door structures are required, necessitating the development of two types of sheet metal, glass, and glass grooves, resulting in high tooling and parts costs and a long development cycle. Conversely, if the installation structure between the front door window frame and the exterior rearview mirror is not modified accordingly, it will be incompatible with electronic... When a traditional exterior rearview mirror is installed on the upper corner of the front door, the size of the mounting structure at the door end of the traditional exterior rearview mirror is reduced, making it difficult to achieve sufficient connection strength between the traditional exterior rearview mirror and the upper corner of the front door. On the other hand, when an electronic exterior rearview mirror is installed on the upper corner of the front door, the size of the upper corner of the front door and the size of the mounting structure at the door end of the electronic exterior rearview mirror are unnecessarily enlarged. This results in increased weight, higher cost, reduced appearance, and increased blind spots for the driver and passengers, thus reducing their side visibility. Summary of the Invention

[0005] This invention provides an installation structure between the front door window frame and the exterior rearview mirror of an automobile, solving the problem that existing installation structures are incompatible with both traditional and electronic exterior rearview mirrors. This leads to a situation where, when the type of exterior rearview mirror needs to be changed, the installation structure must also be modified accordingly. Because the door sheet metal is welded, adjustments cannot be made, requiring two sets of door structures and the development of two different sheet metal, glass, and glass groove designs, resulting in high tooling and parts costs and long development cycles. Conversely, if no corresponding modification is made to the installation structure between the front door window frame and the exterior rearview mirror... The change will reduce the size of the door-end mounting structure of the traditional exterior rearview mirror when it is installed on the upper front door corner panel that is paired with the electronic exterior rearview mirror, making it difficult to achieve sufficient connection strength between the traditional exterior rearview mirror and the upper front door corner panel. On the other hand, when the electronic exterior rearview mirror is installed on the upper front door corner panel that is paired with the traditional exterior rearview mirror, the size of the upper front door corner panel and the size of the door-end mounting structure of the electronic exterior rearview mirror will be unnecessarily enlarged, resulting in increased weight, higher cost, reduced appearance, and increased blind spots for the side visibility of the driver and passengers.

[0006] The technical solution adopted in this invention is: an installation structure between the front door window frame and the exterior rearview mirror of an automobile, including a front door upper corner plate and a reinforcing plate; the lower end of the front door upper corner plate is used to be fixedly connected between the front door outer panel and the front door inner panel, the front end of the front door upper corner plate is used to be fixedly connected to the front door upper frame, and the rear end of the front door upper corner plate is used to be fixedly connected to the front door front guide rail;

[0007] Three electronic exterior rearview mirror mounting holes are provided on the outer side of the upper corner plate of the front door. All three electronic exterior rearview mirror mounting holes extend to the inner side of the upper corner plate of the front door and are arranged in a triangular pattern. The outer side of the upper corner plate of the front door is used to install the electronic exterior rearview mirror or the reinforcing plate.

[0008] The reinforcing plate has three conventional exterior rearview mirror mounting holes corresponding to the three electronic exterior rearview mirror mounting holes, and the outer side of the reinforcing plate is used to mount the conventional exterior rearview mirror.

[0009] The three electronic exterior rearview mirror mounting holes are used to bolt the electronic exterior rearview mirror; the three conventional exterior rearview mirror mounting holes are used to mate with the corresponding three electronic exterior rearview mirror mounting holes to bolt the conventional exterior rearview mirror.

[0010] By setting the reinforcing plate, the installation area of ​​the traditional exterior rearview mirror can be changed from a single-layer plate structure to a two-layer plate structure, thereby strengthening the structure of the exterior rearview mirror installation area and enhancing the connection strength between the traditional exterior rearview mirror and the upper corner plate of the front door. Even after reducing the size of the installation structure at the door end of the traditional exterior rearview mirror, sufficient connection strength can still be maintained between the traditional exterior rearview mirror and the upper corner plate of the front door. This also allows the overall size of the upper corner plate of the front door to be designed to be smaller than that of the existing upper corner plate that is matched with the traditional exterior rearview mirror (because the spacing between the three rearview mirror mounting points (i.e., the three electronic exterior rearview mirror mounting holes) of the upper corner plate of the front door can be smaller than that of the existing upper corner plate that is matched with the traditional exterior rearview mirror). This reduces the side blind spot of the driver and passengers and increases their side field of vision.

[0011] Because the overall size of the front door upper corner plate can be designed to be smaller than that of the front door upper corner plate that is matched with the traditional exterior rearview mirror in the prior art, when the electronic exterior rearview mirror is installed on the front door upper corner plate, the size of the front door upper corner plate and the size of the door end mounting structure of the electronic exterior rearview mirror will not be unnecessarily enlarged, as is the case when the electronic exterior rearview mirror is installed on the front door upper corner plate that is matched with the traditional exterior rearview mirror.

[0012] Furthermore, the installation structure between the car front door window frame and the exterior rearview mirror provided by this invention is compatible with both traditional and electronic exterior rearview mirror installations. When installing a traditional exterior rearview mirror, only the reinforcing plate needs to be installed on the outer side of the upper corner plate of the front door, and then the traditional exterior rearview mirror is installed on the outer side of the reinforcing plate. When installing an electronic exterior rearview mirror, the reinforcing plate is not required; the electronic exterior rearview mirror is directly installed on the outer side of the upper corner plate of the front door. When the type of the car's exterior rearview mirror needs to be changed, there is no need to replace the upper corner plate of the front door, making the replacement process convenient and quick. This solves the problem that existing installation structures between the car front door window frame and the exterior rearview mirror are difficult to be compatible with both traditional and electronic exterior rearview mirror installations. This previously prevented the installation structure between the car front door window frame and the exterior rearview mirror from being replaced when the type of the car's exterior rearview mirror needed to be changed, as the door panel metal was welded... The connection is not adjustable, requiring two sets of door structures and the development of two types of sheet metal, glass, and glass grooves. This leads to high tooling and parts costs and long development cycles. If the mounting structure between the front door window frame and the exterior rearview mirror is not replaced, installing a traditional exterior rearview mirror on the upper front door corner panel (which is compatible with electronic exterior rearview mirrors) would reduce the size of the door-side mounting structure, making it difficult to achieve sufficient connection strength between the traditional mirror and the upper front door corner panel. Conversely, installing an electronic exterior rearview mirror on the upper front door corner panel (which is compatible with traditional exterior rearview mirrors) would unnecessarily enlarge the size of both the upper front door corner panel and the door-side mounting structure of the electronic exterior rearview mirror. This would increase the weight and cost of both the door-side mounting structure and the upper front door corner panel, reduce aesthetics, and increase the blind spot for drivers and passengers, thus decreasing their side visibility.

[0013] Furthermore, the front end of the upper corner plate of the front door extends outward to form a first flange, which is used for welding connection with the lower side of the upper frame of the front door.

[0014] Furthermore, the front end of the reinforcing plate is provided with a first welding part, which is used to weld and connect with the outer side of the front end of the upper corner plate of the front door; the inner side of the lower end of the reinforcing plate is used to weld and connect with the outer side of the lower end of the upper corner plate of the front door.

[0015] Furthermore, the outer side of the lower end of the upper corner panel of the front door is used for welding to the inner side of the upper end of the outer panel of the front door, and the inner side of the lower end of the upper corner panel of the front door is used for welding to the outer side of the upper end of the inner panel of the front door.

[0016] By welding the outer side of the lower end of the upper corner panel of the front door to the inner side of the upper end of the outer panel of the front door, and welding the inner side of the lower end of the upper corner panel of the front door to the outer side of the upper end of the inner panel of the front door, the lower end of the upper corner panel of the front door is clamped between the upper end of the inner panel of the front door and the upper end of the outer panel of the front door, forming a three-layer welded structure of the upper end of the inner panel of the front door, the upper end of the outer panel of the front door, and the lower end of the upper corner panel of the front door, thereby making the connection between the upper end of the inner panel of the front door, the upper end of the outer panel of the front door, and the lower end of the upper corner panel of the front door more stable and reliable.

[0017] Furthermore, the mounting structure between the car front door window frame and the exterior rearview mirror also includes a front door outer panel, the upper end of which is provided with a second welding part for welding connection with the outer side of the lower end of the front door upper corner panel;

[0018] The lower end of the reinforcing plate is provided with a protruding third welding part, which is used to weld and connect with the outer side of the upper corner plate of the front door; the upper end of the second welding part is provided with a clearance groove, which extends along the inner and outer directions of the second welding part and penetrates through the inner and outer sides of the second welding part, and the clearance groove is used to accommodate the third welding part.

[0019] By setting the third welding part and extending it into the clearance groove, a three-layer welding structure is formed between the upper end of the front door inner panel, the third welding part, and the lower end of the front door upper corner panel, thereby making the connection between the upper end of the front door inner panel, the third welding part, and the lower end of the front door upper corner panel more stable and reliable.

[0020] Furthermore, the outer side of the rear end of the upper corner plate of the front door is used for welding connection with the inner side of the front guide rail of the front door; the rear end of the reinforcing plate is used for welding connection with the front side of the front guide rail of the front door.

[0021] By welding the first welded part of the reinforcing plate to the outer side of the front end of the upper corner plate of the front door, welding the inner side of the lower end of the reinforcing plate to the outer side of the lower end of the upper corner plate of the front door, and welding the rear end of the reinforcing plate to the front side of the front guide rail of the front door, the connection and force transmission of the reinforcing plate in the front, rear and lower directions are realized.

[0022] By welding the outer side of the rear end of the upper corner plate of the front door to the inner side of the front guide rail of the front door, and welding the rear end of the reinforcing plate to the front side of the front guide rail of the front door, interference between the rear end of the upper corner plate of the front door and the rear end of the reinforcing plate can be avoided.

[0023] Furthermore, the rear end of the reinforcing plate extends outward to form a second flange. A partition groove is provided on the rear side of the second flange, so that the rear side of the second flange is divided from top to bottom into a first welding surface, the concave surface of the partition groove, and a second welding surface. Both the first welding surface and the second welding surface are used to weld and connect with the front side of the front door guide rail.

[0024] By setting the dividing groove, the concave surface of the dividing groove is set as a non-welding area, so that the rear end of the reinforcing plate is used to separate the welding point with the front side of the front door guide rail into the first welding surface and the second welding surface, so as to avoid excessive stress concentration caused by excessive weld length, resulting in welding deformation and ensuring welding matching accuracy.

[0025] Furthermore, the mounting structure between the car front door window frame and the exterior rearview mirror also includes the front door inner panel; the three electronic exterior rearview mirror mounting holes include a first mounting hole near the front end of the front door upper corner panel and two second mounting holes near the rear end of the front door upper corner panel.

[0026] The top of the front door inner panel has an outwardly protruding connecting part, and the top of the connecting part has a mounting groove. The mounting groove extends along the inside and outside direction of the front door inner panel and penetrates the inside and outside of the connecting part. The mounting groove is correspondingly provided with the first mounting hole. The mounting groove is used to cooperate with the first mounting hole to fix the electronic exterior rearview mirror or the conventional exterior rearview mirror to the front door inner panel with bolts.

[0027] By setting the connecting part and opening the mounting groove at the top of the connecting part, the mounting groove cooperates with the first mounting hole to bolt the electronic exterior rearview mirror or the traditional exterior rearview mirror to the inner front door panel; this strengthens the front mounting point of the exterior rearview mirror (i.e., the location of the first mounting hole and the mounting groove), allowing both the electronic and traditional exterior rearview mirrors to be bolted to the upper corner of the front door and the inner front door panel through the front mounting point of the exterior rearview mirror (i.e., the location of the first mounting hole and the mounting groove). Compared to the solution of only bolting the electronic or traditional exterior rearview mirror to the upper corner of the front door, this increases the connection strength and allows the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror) to be better transmitted to the door through the inner front door panel, thereby reducing the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror).

[0028] Furthermore, the mounting structure between the front door window frame and the exterior rearview mirror also includes a front door upper frame. The front end of the front door inner panel extends outward to form a third flange. The top of the inner side of the front door inner panel is spliced ​​and welded to the bottom of the inner side of the front door upper frame. The top of the front side of the third flange is spliced ​​and welded to the bottom of the front side of the front door upper frame. The end of the third flange extends forward to form a fourth flange. A fourth welding part is provided at the upper end of the front door outer panel. The front end of the front door upper corner plate extends between the fourth flange and the fourth welding part and is welded between the fourth flange and the fourth welding part.

[0029] Unlike existing technologies, which typically involve extending the bottom of the front door upper frame into and fixing it between the front door outer panel and the front door inner panel, and then attaching the front door upper frame to the front side of the front door upper corner panel, the installation structure between the automotive front door window frame and the exterior rearview mirror provided by this invention splices and welds the top of the inner side of the front door inner panel to the bottom of the inner side of the front door upper frame, splices and welds the top of the front side of the third flange to the bottom of the front side of the front door upper frame, and extends the front end of the front door upper corner panel to the area between the fourth flange and the fourth welded part, and welds it between the fourth flange and the fourth welded part. This avoids encroaching on the installation space of the front door upper corner panel by attaching it to the front side of the front door upper corner panel, ensures the connection strength between the front door inner panel and the front door upper frame, reduces the obstruction of the side view of the driver and passengers by the front door upper frame, further reduces the side blind spot of the driver and passengers, and increases the side view of the driver and passengers.

[0030] Furthermore, at least one wiring harness through hole is provided on the upper corner plate of the front door, the wiring harness through hole being used for the wiring harness of the electronic exterior rearview mirror or the conventional exterior rearview mirror to pass through the inner side of the upper corner plate of the front door; a weight reduction hole is provided on the reinforcing plate, the weight reduction hole passing through the inner and outer sides of the reinforcing plate, the weight reduction hole being used to cooperate with the wiring harness through hole, so that the wiring harness of the conventional exterior rearview mirror can pass through the inner side of the upper corner plate of the front door.

[0031] By setting the wiring harness through hole and the weight reduction hole, the wiring harnesses of both the electronic and traditional exterior rearview mirrors can be inserted into the inner side of the upper corner plate of the front door, thus achieving weight reduction of the reinforcing plate.

[0051] The technical solutions of the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings:

[0052] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship of the vehicle, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0053] like Figures 1 to 2 As shown, in the prior art, when installing a traditional exterior rearview mirror, the existing installation structure between the car front door window frame and the exterior rearview mirror usually includes a front door upper corner plate. The lower end of the front door upper corner plate of the existing installation structure between the car front door window frame and the exterior rearview mirror is used to fix it between the front door outer panel 1 and the front door inner panel 2. The front end of the front door upper corner plate of the existing installation structure between the car front door window frame and the exterior rearview mirror is used to fix it to the front door upper frame 3. The rear end of the front door upper corner plate of the existing installation structure between the car front door window frame and the exterior rearview mirror is used to fix it to the front door front guide rail 4.

[0054] The existing installation structure between the front door window frame and the exterior rearview mirror uses three mounting points on the upper corner of the front door for traditional exterior rearview mirrors. Compared to electronic exterior rearview mirrors, traditional exterior rearview mirrors are typically larger and heavier. A larger installation spacing is usually required between the three mounting points to ensure sufficient connection strength between the traditional exterior rearview mirror and the upper corner of the front door. This results in a larger triangular area formed by the three mounting points on the upper corner of the front door, leading to larger dimensions for both the door-side mounting structure and the matching upper corner of the front door. In contrast, electronic exterior rearview mirrors are smaller and lighter, allowing for a smaller door-side mounting structure. This, in turn, enables a smaller upper corner of the front door for electronic exterior rearview mirrors in the existing installation structure between the front door window frame and the exterior rearview mirror.

[0055] like Figure 3 , Figure 7 and Figure 9 As shown, this embodiment provides an installation structure between the front door window frame and the exterior rearview mirror of an automobile, including a front door upper corner plate 5 and a reinforcing plate 6; the lower end of the front door upper corner plate 5 is used to be fixedly connected between the front door outer panel 1 and the front door inner panel 2, the front end of the front door upper corner plate 5 is used to be fixedly connected to the front door upper frame 3, and the rear end of the front door upper corner plate 5 is used to be fixedly connected to the front door front guide rail 4.

[0056] Three electronic exterior rearview mirror mounting holes 51 are provided on the outer side of the upper corner panel 5 of the front door. All three electronic exterior rearview mirror mounting holes 51 extend to the inner side of the upper corner panel 5 of the front door, and the three electronic exterior rearview mirror mounting holes 51 are arranged in a triangular pattern. The outer side of the upper corner panel 5 of the front door is used to install electronic exterior rearview mirrors or reinforcing plates 6.

[0057] The reinforcing plate 6 has three traditional exterior rearview mirror mounting holes 61 corresponding to the three electronic exterior rearview mirror mounting holes 51. The outer side of the reinforcing plate 6 is used to install traditional exterior rearview mirrors.

[0058] Three electronic exterior rearview mirror mounting holes 51 are used to bolt the electronic exterior rearview mirror; three conventional exterior rearview mirror mounting holes 61 are used to mate with the corresponding three electronic exterior rearview mirror mounting holes 51 to bolt the conventional exterior rearview mirror.

[0059] By setting the reinforcing plate 6, the installation area of ​​the traditional exterior rearview mirror can be changed from a single-layer plate installation structure to a two-layer plate installation structure, thereby strengthening the structure of the exterior rearview mirror installation area and enhancing the connection strength between the traditional exterior rearview mirror and the upper corner plate 5 of the front door. Even after reducing the size of the installation structure at the door end of the traditional exterior rearview mirror, sufficient connection strength can still be maintained between the traditional exterior rearview mirror and the upper corner plate 5 of the front door. This also allows the overall size of the upper corner plate 5 of the front door to be designed to be smaller than that of the upper corner plate 5 of the front door that is matched with the traditional exterior rearview mirror in the prior art (because the distance between the three rearview mirror mounting points (i.e., the three electronic exterior rearview mirror mounting holes 51) of the upper corner plate 5 of the front door can be smaller than that of the upper corner plate 5 of the front door that is matched with the traditional exterior rearview mirror in the prior art). This reduces the side blind spot of the driver and passengers and increases the side field of vision of the driver and passengers.

[0060] Because the front door upper corner plate 5 is smaller in overall size than the front door upper corner plate 5 that is matched with the traditional exterior rearview mirror in the existing technology, when installing the electronic exterior rearview mirror on the front door upper corner plate 5, there will be no problem of the size of the front door upper corner plate 5 and the size of the door end mounting structure of the electronic exterior rearview mirror being unnecessarily enlarged, as is the case when installing the electronic exterior rearview mirror on the front door upper corner plate 5 that is matched with the traditional exterior rearview mirror.

[0061] Furthermore, the installation structure between the car front door window frame and the exterior rearview mirror provided by this invention is compatible with both traditional and electronic exterior rearview mirror installations. When installing a traditional exterior rearview mirror, only a reinforcing plate 6 needs to be installed on the outer side of the upper corner plate 5 of the front door, and then the traditional exterior rearview mirror is installed on the outer side of the reinforcing plate 6. When installing an electronic exterior rearview mirror, the reinforcing plate 6 is not required; the electronic exterior rearview mirror can be directly installed on the outer side of the upper corner plate 5 of the front door. When it is necessary to change the type of the car's exterior rearview mirror, there is no need to replace the upper corner plate 5 of the front door, making the replacement operation convenient and quick. This solves the problem that the existing installation structure between the car front door window frame and the exterior rearview mirror is difficult to be compatible with both traditional and electronic exterior rearview mirror installations. This leads to a situation where, when it is necessary to change the type of the car's exterior rearview mirror, if the installation structure between the car front door window frame and the exterior rearview mirror is also replaced accordingly, it would be impossible to change the installation structure because the door panel metal is welded together. The corresponding adjustments necessitate the use of two sets of door structures, requiring the development of two types of sheet metal, glass, and glass grooves. This results in high tooling and parts costs and long development cycles. Furthermore, if the mounting structure between the front door window frame and the exterior rearview mirror is not replaced accordingly, installing a traditional exterior rearview mirror on the upper front door corner panel, which is compatible with the electronic exterior rearview mirror, would reduce the size of the door-end mounting structure, making it difficult to achieve sufficient connection strength between the traditional mirror and the upper front door corner panel. Conversely, installing an electronic exterior rearview mirror on the upper front door corner panel, which is compatible with the traditional mirror, would unnecessarily enlarge the size of both the upper front door corner panel and the door-end mounting structure of the electronic exterior rearview mirror. This would increase the weight and cost of both the door-end mounting structure and the upper front door corner panel, reduce aesthetics, and increase the blind spot for drivers and passengers, thus decreasing their side visibility.

[0062] Furthermore, such as Figure 3 and Figure 5 As shown, the front end of the upper corner plate 5 of the front door extends outward to form a first flange 52, which is used to weld and connect with the lower side of the upper frame 3 of the front door.

[0063] Furthermore, such as Figure 3 , Figure 5 and Figure 8 As shown, the front end of the reinforcing plate 6 is provided with a first welding part 62, which is used to weld and connect with the outer side of the front end of the upper corner plate 5 of the front door; the inner side of the lower end of the reinforcing plate 6 is used to weld and connect with the outer side of the lower end of the upper corner plate 5 of the front door.

[0064] Furthermore, such as Figure 3 , Figure 4 and Figure 9As shown, the outer side of the lower end of the upper corner panel 5 of the front door is used to weld and connect with the inner side of the upper end of the outer panel 1 of the front door, and the inner side of the lower end of the upper corner panel 5 of the front door is used to weld and connect with the outer side of the upper end of the inner panel 2 of the front door.

[0065] By welding the outer side of the lower end of the upper corner panel 5 to the inner side of the upper end of the outer panel 1 of the front door, and welding the inner side of the lower end of the upper end of the upper corner panel 5 to the outer side of the upper end of the inner panel 2 of the front door, the lower end of the upper corner panel 5 is clamped between the upper end of the inner panel 2 of the front door and the upper end of the outer panel 1 of the front door, forming a three-layer welded structure, thereby making the connection between the upper end of the inner panel 2 of the front door, the upper end of the outer panel 1 of the front door, and the lower end of the upper corner panel 5 of the front door more stable and reliable.

[0066] Furthermore, such as Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the mounting structure between the front door window frame and the exterior rearview mirror also includes a front door outer panel 1, and the upper end of the front door outer panel 1 is provided with a second welding part 11 for welding connection with the outer side of the lower end of the front door upper corner panel 5.

[0067] The lower end of the reinforcing plate 6 is provided with a protruding third welding part 63, which is used to weld and connect with the outer side of the upper corner plate 5 of the front door; the upper end of the second welding part 11 is provided with a relief groove 111, which extends along the inner and outer directions of the second welding part 11 and penetrates the inner and outer sides of the second welding part 11, and the relief groove 111 is used to accommodate the third welding part 63.

[0068] By setting a third welding part 63 and extending it into the clearance groove 111, a three-layer welding structure is formed between the upper end of the front door inner panel 2, the third welding part 63, and the lower end of the front door upper corner panel 5, thereby making the connection between the upper end of the front door inner panel 2, the third welding part 63, and the lower end of the front door upper corner panel 5 more stable and reliable.

[0069] Furthermore, such as Figure 3 and Figure 6 As shown, the outer side of the rear end of the upper corner plate 5 of the front door is used for welding connection with the inner side of the front guide rail 4 of the front door; the rear end of the reinforcing plate 6 is used for welding connection with the front side of the front guide rail 4 of the front door.

[0070] By welding the first welding part 62 of the reinforcing plate 6 to the outer side of the front end of the upper corner plate 5 of the front door, welding the inner side of the lower end of the reinforcing plate 6 to the outer side of the lower end of the upper corner plate 5 of the front door, and welding the rear end of the reinforcing plate 6 to the front side of the front guide rail 4 of the front door, the connection and force transmission of the reinforcing plate 6 in the front, rear and lower directions are realized.

[0071] By welding the outer side of the rear end of the upper corner plate 5 of the front door to the inner side of the front guide rail 4 of the front door, and welding the rear end of the reinforcing plate 6 to the front side of the front guide rail 4 of the front door, interference between the rear end of the upper corner plate 5 of the front door and the rear end of the reinforcing plate 6 can be avoided.

[0072] Furthermore, such as Figure 6 and Figure 8 As shown, the rear end of the reinforcing plate 6 extends outward to form a second flange 64. A partition groove 641 is provided on the rear side of the second flange 64, so that the rear side of the second flange 64 is divided from top to bottom into a first welding surface 642, the concave surface of the partition groove 641, and a second welding surface 643. The first welding surface 642 and the second welding surface 643 are both used for welding connection with the front side of the front door guide rail 4.

[0073] By setting the partition groove 641, the concave surface of the partition groove 641 is set as a non-welding area, so that the rear end of the reinforcing plate 6 is separated from the welding point of the front side of the front door guide rail 4 into a first welding surface 642 and a second welding surface 643, so as to avoid excessive stress concentration caused by excessive weld length, resulting in welding deformation and ensuring welding matching accuracy.

[0074] Furthermore, such as Figure 7 , Figure 9 and Figure 10 As shown, the mounting structure between the front door window frame and the exterior rearview mirror also includes the front door inner panel 2; the three electronic exterior rearview mirror mounting holes 51 include a first mounting hole 511 near the front end of the front door upper corner panel 5 and two second mounting holes 512 near the rear end of the front door upper corner panel 5.

[0075] The top of the front door inner panel 2 has an outwardly protruding connecting part 21. The top of the connecting part 21 has a mounting groove 211. The mounting groove 211 extends along the inside and outside direction of the front door inner panel 2 and passes through the inside and outside of the connecting part 21. The mounting groove 211 is correspondingly provided with the first mounting hole 511. The mounting groove 211 is used to cooperate with the first mounting hole 511 to fix the electronic exterior rearview mirror or the conventional exterior rearview mirror bolts on the front door inner panel 2.

[0076] By setting a connecting part 21 and opening a mounting groove 211 at the top of the connecting part 21, the mounting groove 211 cooperates with the first mounting hole 511 to bolt the electronic exterior rearview mirror or the traditional exterior rearview mirror to the front door inner panel 2; this strengthens the front mounting point of the exterior rearview mirror (i.e., the first mounting hole 511 and the mounting groove 211), so that both the electronic and traditional exterior rearview mirrors can be bolted to the front door upper corner panel 5 and the front door inner panel 2 through the front mounting point of the exterior rearview mirror (i.e., the first mounting hole 511 and the mounting groove 211). Compared with the solution of only bolting the electronic or traditional exterior rearview mirror to the front door upper corner panel 5, this increases the connection strength and allows the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror) to be better transmitted to the door through the front door inner panel 2, thereby reducing the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror).

[0077] Furthermore, such as Figure 7 , Figure 9 and Figure 10 As shown, the installation structure between the front door window frame and the exterior rearview mirror also includes the front door upper frame 3. The front end of the front door inner panel 2 extends outward to form a third flange 22. The top of the inner side of the front door inner panel 2 is spliced ​​and welded to the bottom of the inner side of the front door upper frame 3. The top of the front side of the third flange 22 is spliced ​​and welded to the bottom of the front side of the front door upper frame 3. The end of the third flange 22 extends forward to form a fourth flange 23. The upper end of the front door outer panel 1 is provided with a fourth welding part 12. The front end of the front door upper corner panel 5 extends to the space between the fourth flange 23 and the fourth welding part 12 and is welded between the fourth flange 23 and the fourth welding part 12.

[0078] Unlike existing technologies, which typically involve extending and fixing the bottom end of the front door upper frame 3 between the front door outer panel 1 and the front door inner panel 2, and attaching the front door upper frame 3 to the front side of the front door upper corner panel 5, the installation structure between the automotive front door window frame and the exterior rearview mirror provided by this invention involves welding the top end of the inner side of the front door inner panel 2 to the bottom end of the inner side of the front door upper frame 3, and welding the top end of the front side of the third flange 22 to the bottom end of the front side of the front side of the front door upper frame 3. The front end of the plate 5 extends between the fourth flange 23 and the fourth welding part 12, and is welded between the fourth flange 23 and the fourth welding part 12; this avoids squeezing the installation space of the front door upper corner plate 5 by attaching the front door upper frame 3 to the front side of the front door upper corner plate 5, and also ensures the connection strength between the front door inner plate 2 and the front door upper frame 3, reduces the obstruction of the side view of the driver and passengers by the front door upper frame 3, further reduces the side blind spot of the driver and passengers, and increases the side view of the driver and passengers.

[0079] Furthermore, such as Figure 7 and Figure 8As shown, at least one wiring harness through hole 53 is provided on the upper corner plate 5 of the front door. The wiring harness through hole 53 is used for the wiring harness of the electronic or conventional exterior rearview mirror to pass through the inner side of the upper corner plate 5 of the front door. The reinforcing plate 6 is provided with a weight reduction hole 65, which passes through the inner and outer sides of the reinforcing plate 6. The weight reduction hole 65 is used to cooperate with the wiring harness through hole 53 so that the wiring harness of the conventional exterior rearview mirror can pass through the inner side of the upper corner plate 5 of the front door.

[0080] By setting the wiring harness through hole 53 and the weight reduction hole 65, the wiring harnesses of both the electronic and traditional exterior rearview mirrors can be inserted into the inner side of the upper corner plate 5 of the front door, which also reduces the weight of the reinforcing plate 6.

[0081] The installation structure between the front door window frame and the exterior rearview mirror of an automobile provided by this invention has at least the following technical effects or advantages:

[0082] 1. By setting the reinforcing plate 6, the installation area of ​​the traditional exterior rearview mirror can be changed from a single-layer plate installation structure to a two-layer plate installation structure, thereby strengthening the structure of the exterior rearview mirror installation area and enhancing the connection strength between the traditional exterior rearview mirror and the upper corner plate 5 of the front door. Even after reducing the size of the installation structure at the door end of the traditional exterior rearview mirror, sufficient connection strength can still be maintained between the traditional exterior rearview mirror and the upper corner plate 5 of the front door. This also allows the overall size of the upper corner plate 5 of the front door to be designed to be smaller than that of the upper corner plate 5 of the front door that is matched with the traditional exterior rearview mirror in the prior art (because the distance between the three rearview mirror mounting points (i.e., the three electronic exterior rearview mirror mounting holes 51) of the upper corner plate 5 of the front door can be smaller than that of the upper corner plate 5 of the front door that is matched with the traditional exterior rearview mirror in the prior art). This reduces the side blind spot of the driver and passengers and increases the side field of vision of the driver and passengers.

[0083] Because the front door upper corner plate 5 is smaller in overall size than the front door upper corner plate 5 that is matched with the traditional exterior rearview mirror in the existing technology, when installing the electronic exterior rearview mirror on the front door upper corner plate 5, there will be no problem of the size of the front door upper corner plate 5 and the size of the door end mounting structure of the electronic exterior rearview mirror being unnecessarily enlarged, as is the case when installing the electronic exterior rearview mirror on the front door upper corner plate 5 that is matched with the traditional exterior rearview mirror.

[0084] Furthermore, the installation structure between the car front door window frame and the exterior rearview mirror provided by this invention is compatible with both traditional and electronic exterior rearview mirror installations. When installing a traditional exterior rearview mirror, only a reinforcing plate 6 needs to be installed on the outer side of the upper corner plate 5 of the front door, and then the traditional exterior rearview mirror is installed on the outer side of the reinforcing plate 6. When installing an electronic exterior rearview mirror, the reinforcing plate 6 is not required; the electronic exterior rearview mirror can be directly installed on the outer side of the upper corner plate 5 of the front door. When it is necessary to change the type of the car's exterior rearview mirror, there is no need to replace the upper corner plate 5 of the front door, making the replacement operation convenient and quick. This solves the problem that the existing installation structure between the car front door window frame and the exterior rearview mirror is difficult to be compatible with both traditional and electronic exterior rearview mirror installations, which leads to the need to use two sets of mirrors when changing the type of the car's exterior rearview mirror because the door panel is welded and cannot be adjusted accordingly. The door structure necessitates the development of two types of sheet metal, glass, and glass grooves, leading to high tooling and parts costs and long development cycles. Furthermore, if the mounting structure between the front door window frame and the exterior rearview mirror is not correspondingly replaced, installing a traditional exterior rearview mirror on the upper front door corner panel, which is compatible with electronic exterior rearview mirrors, would reduce the size of the door-end mounting structure of the traditional exterior rearview mirror, resulting in insufficient connection strength between the traditional exterior rearview mirror and the upper front door corner panel. Conversely, installing an electronic exterior rearview mirror on the upper front door corner panel, which is compatible with traditional exterior rearview mirrors, would unnecessarily enlarge the size of both the upper front door corner panel and the door-end mounting structure of the electronic exterior rearview mirror. This would increase the weight and cost of both the door-end mounting structure of the electronic exterior rearview mirror and the upper front door corner panel, reduce aesthetics, and increase the side blind spot for drivers and passengers, thus decreasing their side visibility.

[0085] 2. By welding the outer side of the lower end of the upper corner panel 5 to the inner side of the upper end of the outer panel 1 of the front door, and welding the inner side of the lower end of the upper end of the upper corner panel 5 to the outer side of the upper end of the inner panel 2 of the front door, the lower end of the upper corner panel 5 is clamped between the upper end of the inner panel 2 of the front door and the upper end of the outer panel 1 of the front door, forming a three-layer welded structure of the upper end of the inner panel 2 of the front door, the upper end of the outer panel 1 of the front door, and the lower end of the upper corner panel 5 of the front door, thereby making the connection between the upper end of the inner panel 2 of the front door, the upper end of the outer panel 1 of the front door, and the lower end of the upper corner panel 5 of the front door more stable and reliable.

[0086] 3. By setting a third welding part 63, the third welding part 63 is inserted into the clearance groove 111, so that the upper end of the front door inner panel 2, the third welding part 63 and the lower end of the front door upper corner panel 5 form a three-layer welding structure, thereby making the connection between the upper end of the front door inner panel 2, the third welding part 63 and the lower end of the front door upper corner panel 5 more stable and reliable.

[0087] 4. By welding the first welding part 62 of the reinforcing plate 6 to the outer side of the front end of the upper corner plate 5 of the front door, welding the inner side of the lower end of the reinforcing plate 6 to the outer side of the lower end of the upper corner plate 5 of the front door, and welding the rear end of the reinforcing plate 6 to the front side of the front guide rail 4 of the front door, the connection and force transmission of the reinforcing plate 6 in the front, rear and lower directions are realized.

[0088] 5. By welding the outer side of the rear end of the upper corner plate 5 of the front door to the inner side of the front guide rail 4 of the front door, and welding the rear end of the reinforcing plate 6 to the front side of the front guide rail 4 of the front door, interference between the rear end of the upper corner plate 5 of the front door and the rear end of the reinforcing plate 6 can be avoided.

[0089] 6. By setting the partition groove 641, the concave surface of the partition groove 641 is set as a non-welding area, so that the rear end of the reinforcing plate 6 is separated from the front side of the front door guide rail 4 for welding into the first welding surface 642 and the second welding surface 643, so as to avoid excessive stress concentration caused by excessive weld length, resulting in welding deformation and ensuring welding matching accuracy.

[0090] 7. By setting a connecting part 21 and opening a mounting groove 211 at the top of the connecting part 21, the mounting groove 211 cooperates with the first mounting hole 511 to bolt the electronic exterior rearview mirror or the traditional exterior rearview mirror to the front door inner panel 2; this strengthens the front mounting point of the exterior rearview mirror (i.e., the first mounting hole 511 and the mounting groove 211), so that both the electronic and traditional exterior rearview mirrors can be bolted to the front door upper corner panel 5 and the front door inner panel 2 through the front mounting point of the exterior rearview mirror (i.e., the first mounting hole 511 and the mounting groove 211). Compared with the solution of only bolting the electronic or traditional exterior rearview mirror to the front door upper corner panel 5, this increases the connection strength and allows the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror) to be better transmitted to the door through the front door inner panel 2, thereby reducing the vibration of the exterior rearview mirror (i.e., the electronic or traditional exterior rearview mirror).

[0091] 8. Unlike existing technologies, which typically involve extending and fixing the bottom end of the front door upper frame 3 between the front door outer panel 1 and the front door inner panel 2, and attaching the front door upper frame 3 to the front side of the front door upper corner panel 5, the installation structure between the car front door window frame and the exterior rearview mirror provided by this invention involves welding the top end of the inner side of the front door inner panel 2 to the bottom end of the inner side of the front door upper frame 3, and welding the top end of the front side of the third flange 22 to the bottom end of the front side of the front door upper frame 3. The front end of the corner plate 5 extends between the fourth flange 23 and the fourth welding part 12, and is welded between the fourth flange 23 and the fourth welding part 12; this avoids squeezing the installation space of the front door upper corner plate 5 by attaching the front door upper frame 3 to the front side of the front door upper corner plate 5, and also ensures the connection strength between the front door inner panel 2 and the front door upper frame 3, reduces the obstruction of the side view of the driver and passengers by the front door upper frame 3, further reduces the side blind spot of the driver and passengers, and increases the side view of the driver and passengers.

[0092] 9. By setting the wiring harness through hole 53 and the weight reduction hole 65, the wiring harnesses of both the electronic and traditional exterior rearview mirrors can be inserted into the inner side of the upper corner plate 5 of the front door, which also reduces the weight of the reinforcing plate 6.

[0093] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should be considered within the protection scope of the present invention.
