The rearview mirror mounting plate 11 of the present invention welds the front door outer panel reinforcement plate 16, the window frame upper frame 12, the window frame guide rail assembly 13, and the inner window sill reinforcement plate 15 together through densely arranged weld points surrounding the central recessed portion 11a. This significantly enhances the weld stiffness between the rearview mirror mounting plate 11 and the front door window frame assembly 1, preventing problems such as rearview mirror vibration.
[0027] Furthermore, the welding conditions of the front door inner panel assembly 2 are described from the A-pillar side and the B-pillar side in the length direction of the vehicle body and the inside-outside direction in the width direction of the vehicle body. On the A-pillar side, the rearview mirror mounting plate 11 is welded to the front door inner panel assembly 2 as one, and the welding point between the rearview mirror mounting plate 11 and the front door inner panel assembly 2 is located at the front end of the front door inner panel assembly 2, and the welding point between the front end of the inner window sill reinforcement plate 15 and the front door inner panel assembly 2 is located at the front end of the front door inner panel assembly 2; on the B-pillar side, the welding point between the rear end of the inner window sill reinforcement plate 15 and the front door inner panel assembly 2 is located at the rear end of the front door inner panel assembly 2; in the inside-outside direction, the welding point between the rearview mirror mounting plate 11 and the front door inner panel assembly 2 is located on the inside of the rearview mirror mounting plate 11, and the welding point between the front end of the inner window sill reinforcement plate 15 and the front door inner panel assembly 2 is located on the inside of the rearview mirror mounting plate 11. Specifically, the front door inner panel assembly 2 and the front door window frame assembly 1 are welded together through the welding area located on the A-pillar side and the welding area on the B-pillar side. The front end of the front door inner panel assembly 2 is located on the A-pillar side, and the rear end of the front door inner panel assembly 2 is located on the B-pillar side. Therefore, the front end of the front door inner panel assembly 2 and the rear end of the front door inner panel assembly 2 need to be welded to the parts on the A-pillar side and the B-pillar side of the front door window frame assembly 1 respectively during assembly. Before welding the front door inner panel assembly 2 to the front door window frame assembly 1, the welding assembly of the front door inner panel assembly 2 itself and the welding assembly of the front door window frame assembly 1 itself need to be completed separately. When welding and assembling the front door and window frame assembly 1, first weld the rearview mirror mounting plate 11, the front door outer panel reinforcement plate 16 and the window frame guide rail assembly 13 into one small assembly, weld the window frame upper frame 12, the window frame B-pillar assembly 14 and the inner window sill reinforcement plate 15 into one small assembly, and then weld the above two small assemblies into one to complete the assembly of the front door and window frame assembly 1; when welding and assembling the front door inner panel assembly 2, it is necessary to weld the first hinge mounting plate 21 and the second hinge mounting plate 22 to the front door inner panel assembly 2 respectively. When welding the front door inner panel assembly 2 and the front door window frame assembly 1, it is necessary to spot weld the rearview mirror mounting plate 11 on the A-pillar side and the first hinge mounting plate 21 together, weld the front end of the inner window sill reinforcement plate 15 to the front end of the front door inner panel assembly 2 together, and weld the inner window sill reinforcement plate 15 on the B-pillar side to the rear end of the front door inner panel assembly 2 and the window frame B-pillar assembly 14 together. In the process of welding the front door inner panel assembly 2 and the front door window frame assembly 1, since the rearview mirror mounting plate 11 and the first hinge mounting plate 21 are respectively located on the front door window frame assembly 1 and the front door inner panel assembly 2, an arc welding gap can also be designed on the A-pillar side like the B-pillar side. In this embodiment, an arc welding gap of 0.5mm is reserved on the A-pillar side and the B-pillar side respectively, and the width of the window frame and the size chain tolerance of the inner panel are thereby increased by 1mm, which effectively reduces the welding difficulty and improves dimensional compatibility.
[0028] Furthermore, the present invention also includes a car, which includes the aforementioned door and window frame structure.
[0029] In summary, the vehicle door window frame structure of the present invention separately arranges a rearview mirror mounting plate for mounting a rearview mirror and a first hinge mounting plate for mounting a hinge, welds the two to the front door window frame assembly and the front door inner panel assembly respectively, and then welds the front door window frame assembly and the front door inner panel assembly into one, so that the rearview mirror mounting plate does not need to be fitted with the front door inner panel assembly during welding and assembly, so that arc welding gaps can be reserved on the A-pillar side and the B-pillar side of the front door window frame assembly and the front door inner panel assembly respectively, thereby increasing the width of the window frame and the dimensional chain tolerance of the inner panel, reducing the opening size accuracy requirements and assembly difficulty of the window frame, and also reducing the rigidity requirements for the rearview mirror mounting plate. In addition, the rearview mirror mounting plate in the utility model welds the front door outer panel reinforcement plate, the window frame upper frame, the window frame guide rail assembly and the inner window sill reinforcement plate into one through welding points densely arranged around the central recessed portion, which greatly enhances the welding stiffness of the rearview mirror mounting plate and the front door window frame assembly, and avoids problems such as rearview mirror shaking.
