[0039] Please refer to Figures 1 to 13, the vehicle door frame reinforcement structure provided by the present utility model will be described hereinafter. The vehicle door frame reinforcement structure includes: a vehicle door inner panel assembly 3, an outside rearview mirror mounting plate assembly 1, and an outer panel reinforcement plate assembly 2; the outside rearview mirror mounting plate assembly 1 is connected to the inner side surface of the vehicle door inner panel assembly 3 and is located in the front triangular area of the front vehicle door frame; the outer panel reinforcement plate assembly 2 is connected to the inner side surface of the vehicle door inner panel assembly 3 and is located inside the outside rearview mirror mounting plate assembly 1; the outer panel reinforcement plate assembly 2 includes an outer panel reinforcement plate 21 and a support plate 23, the outer panel reinforcement plate 21 is connected to the lower edge of the front vehicle door frame, and the support plate 23 is connected between the outer panel reinforcement plate 21 and the outside rearview mirror mounting plate assembly 1; after the outside rearview mirror mounting plate assembly 1, the outer panel reinforcement plate assembly 2 and the vehicle door inner panel assembly 3 are connected, the front triangular area is divided into an upper open cavity 6 and a lower open cavity 7 by the support plate 23.

[0040] The vehicle door frame reinforcement structure provided by the present utility model forms upper and lower open cavities in the front triangular area of the outside rearview mirror installation through the connection of the support plate 23. The upper open cavity 6 directly strengthens the front vehicle door frame, and the lower open cavity 7 can reinforce the structure of the front vehicle door frame. Therefore, through the connection of the support plate 23, the stiffness of the front triangular area of the vehicle door frame is improved, providing a sufficiently high stiffness and regional mode for the installation of the outside rearview mirror, thereby enhancing the stability of the outside rearview mirror installation.

[0041] In this application, the front and rear ends of the outer panel reinforcement plate 21 are respectively fixed on the front and rear sides of the vehicle door inner panel assembly 3, and a cavity is formed between the outer panel reinforcement plate 21 and the vehicle door inner panel assembly 3; the outside rearview mirror mounting plate 11 is closely mounted on the inner side surface of the vehicle door inner panel assembly 3, and the support plate 23 is connected between the outside rearview mirror mounting plate 11 and the outer panel reinforcement plate 21, thereby forming upper and lower open cavities; the opening of the upper open cavity 6 faces the vehicle interior side, and the opening of the lower open cavity 7 faces downward.

[0042] In some embodiments, as shown in Figures 1 to 4 , the outer panel reinforcement plate assembly 2 further includes a reinforcing plate 22 connected to the inner side of the outer panel reinforcement plate 21. The reinforcing plate 22 is located below the front triangular area. After the reinforcing plate 22 is connected to the outer panel reinforcement plate 21, a first closed cavity 5 closed in the up-down direction is formed, and the positive projection of the first closed cavity 5 in the in-out direction falls within the lower open cavity 7. In this application, the reinforcing plate 22 is located below the front triangular area of the outside rearview mirror installation, reinforcing the front triangular area and further enhancing the installation strength and regional mode of the outside rearview mirror. The upper and lower edges of the reinforcing plate 22 overlap with the outer panel reinforcement plate 21 and are connected by two layers of welding points, forming a closed cavity, enhancing the stiffness of the outer panel reinforcement plate assembly 2, thereby reinforcing the mode of the outside rearview mirror installation area.

[0043] The first closed cavity 5 in this application is located within the upper open cavity 6, further strengthening the front triangular area on the basis of the upper open cavity 6.

[0044] In some embodiments, referring to Figure 3 and Figure 4 as shown, the upper edge of the support plate 23, the outer rearview mirror mounting plate assembly 1 and the inner door panel assembly 3 form a three-layer overlap and are connected by three layers of solder joints; the lower edge of the support plate 23, the upper edge of the reinforcing plate 22 and the upper edge of the outer panel reinforcement plate 21 form a three-layer overlap and are connected by three layers of solder joints; the lower edge of the reinforcing plate 22 and the lower edge of the outer panel reinforcement plate 21 overlap to form a two-layer overlap. The three-layer solder joints and two-layer solder joints formed in this application improve the connection strength between components, thus facilitating the stability after the outer rearview mirror is installed.

[0045] Referring to Figure 12 , the support plate 23 of this application is integrally in a Z-shaped structure. The component itself improves its own stiffness through bending, and it is also conducive to the large-area overlap between components and the formation of a multi-step structure.

[0046] In some embodiments, referring to Figure 11 , a concave platform 222 recessed toward the outer panel reinforcement plate 21 is provided in the middle of the reinforcing plate 22. After the support plate 23, the reinforcing plate 22 and the outer panel reinforcement plate 21 are connected, a multi-step structure is formed in the front triangular area. The concave platform 222 in the middle of the reinforcing plate 22 is conducive to improving the stiffness of the component itself, and is also conducive to the formation of a multi-step structure. The multi-step structure is also conducive to improving the stiffness of the front triangular area.

[0047] Referring to Figure 3 as shown, the multi-step structure of this application includes three step surfaces. Among them, the concave platform 222 is the first step surface 8. Then, from bottom to top, they are the first step surface 8, the second step surface 9 (the part where the reinforcing plate 22, the outer panel reinforcement plate 21 and the support plate 23 overlap in three layers) and the third step surface 10 (the part where the support plate 23, the reinforcing plate 22 and the outer rearview mirror mounting plate 11 overlap in three layers).

[0048] In some embodiments, referring to Figures 9 to 10 , the upper edge of the reinforcing plate 22 has an inward flanging 221 bent toward the vehicle interior, and the lower edge of the support plate 23 has an outward flanging 231 bent toward the vehicle exterior. The three-layer overlap of the support plate 23, the reinforcing plate 22 and the outer rearview mirror mounting plate 11 plays a role of a bridge in strengthening the front triangular area by the outer panel reinforcement plate 21 and the reinforcing plate 22. Therefore, flangings are respectively provided on these two components here to improve the stiffness of the overlapping position, thereby improving the stiffness of the outer rearview mirror installation.

[0049] In some embodiments, referring to Figure 12, the support plate 23 is also provided with a reinforcing rib 232, and the reinforcing rib 232 extends from the outer plate reinforcing plate 21 toward the direction of the outer rearview mirror mounting plate assembly 1. The support plate 23 is connected between the outer plate reinforcing plate 21 and the outer plate reinforcing plate 21, and is also a bridge for transmitting the mode of the outer rearview mirror mounting plate 11 to the outer plate reinforcing plate 21. Therefore, the support plate 23 needs to have sufficient rigidity to enable the outer plate reinforcing plate 21 and the reinforcement plate 22 to play a reinforcing role. The present application further improves the rigidity of the support plate 23 itself by setting the reinforcing rib 232, thereby ensuring the effectiveness of the outer plate reinforcing plate assembly 2 in improving the strength of the front triangular area.

[0050] In some embodiments, see Figures 1 to 8 As shown, the exterior mirror mounting plate assembly 1 includes an exterior mirror mounting plate 11, a window frame front guide rail 13 and a connecting bracket 12. The exterior mirror mounting plate 11 is connected to the front triangular area; the window frame front guide rail 13 is connected to the rear side of the exterior mirror mounting plate 11; the connecting bracket 12 is connected between the exterior mirror mounting plate 11 and the outer panel reinforcement plate 21; the support plate 23 is connected to the exterior mirror mounting plate 11; after the connecting bracket 12 is connected, the exterior mirror mounting plate assembly 1, the outer panel reinforcement plate assembly 2 and the door inner panel assembly 3 form a second closed cavity 4 closed along the front-to-back direction, and the second closed cavity 4 is located below the front triangular area. The present application forms a second closed cavity 4 by connecting the connecting bracket 12 between the exterior mirror mounting plate 11 and the outer panel reinforcement plate 21. The front-to-back direction of the second closed cavity 4 spans the door inner panel assembly 3, which greatly strengthens the window frame rigidity.

[0051] Among them, the first closed cavity 5 is closed in the up and down direction, and its orthographic projection in the front and back direction falls into the second closed cavity 4, thus forming a reinforced structure of multiple cavities superimposed, which can greatly improve the stiffness and mode of the exterior rearview mirror installation area.

[0052] Due to the irregularity of the outer panel reinforcement plate 21 and the exterior rearview mirror mounting plate 11, the cross-sectional areas of the second closed cavity 4 along the left and right directions are different, thereby forming a closed cavity with a variable cross-section, which is also beneficial to the improvement of the mode of the exterior rearview mirror mounting area.

[0053] The present application forms multiple cavity reinforcement structures and step multi-bend connection structures by connecting the support plate 23 with the connecting bracket 12, which effectively improves the rigidity of the door and window frame and successfully solves the problems of weak rigidity of the door and window frame and insufficient modality of the exterior rearview mirror.

[0054] Since the connection point of the support plate 23 and the connection point of the connection bracket 12 are misaligned in the up-down direction and the front-back direction, a misaligned closed cavity is formed between the two, which has a further reinforcement effect on the front triangle area.

[0055] In some embodiments, see Figure 6As shown in the figure, the front and rear sides of the outer rearview mirror mounting plate 11 are respectively provided with a front flanging 112 and a rear flanging 111 extending towards the interior of the vehicle. The front window frame guide rail 13 is connected to the rear side of the rear flanging 111; the connecting bracket 12 is connected between the rear flanging 111 and the outer panel reinforcement plate 21. Through the front flanging 112 and the rear flanging 111, the outer rearview mirror mounting plate 11 is an overall open U-shaped cavity structure, and the two side flangings are used for self-strengthening and lapping with surrounding components, improving the firmness of the connection between components.

[0056] For example, the lapping of the connecting bracket 12 and the rear flanging 111; the lapping of the front flanging 112 and the flanging of the vehicle door inner panel assembly 3. In order to further improve the stiffness of the component itself and the firmness of lapping with surrounding components, the front flanging 112 and the rear flanging 111 are designed with concave-convex undulating strengthening structures.

[0057] In some embodiments, refer to Figure 6 and Figure 8 As shown in the figure, the connecting bracket 12 protrudes towards the front window frame guide rail 13 to form a U-shaped bending portion 121, and the U-shaped bending portion 121 is connected to the outer side surface of the outer panel reinforcement plate 21. The connecting bracket 12 forms a multi-bending structure through the designed U-shaped bending portion 121, which can improve the stiffness of the connecting bracket 12 itself, thereby facilitating the improvement of the stiffness and mode of the outer rearview mirror installation area.

[0058] In the above embodiments, the descriptions of each embodiment have their own focuses. For parts not detailed or recorded in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0059] Based on the same inventive concept, the embodiments of the present application further provide a vehicle, including the vehicle window frame strengthening structure described above.

[0060] For the vehicle provided by the embodiments of the present utility model, since the outer panel reinforcement plate assembly 2 is provided in the front triangular area where the outer rearview mirror of the front window frame is installed, and two upper and lower open cavities are formed to strengthen and reinforce the front triangular area, the stability of the installation of the outer rearview mirror of the whole vehicle is improved.

[0061] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
