Referring to fig. 1 and 2, fig. 1 is a schematic structural view of an embodiment of a door assembly provided in the present application; FIG. 2 is a schematic view of the door assembly of FIG. 1 taken along the direction A-A. In one aspect of the present application, a vehicle door assembly is provided, in a specific embodiment, for enhancing the strength of an a-pillar hinge mounting point, which includes an a-pillar reinforcement plate 10, an a-pillar hinge reinforcement plate 20, and a pre-adjustment plate 30, wherein the pre-adjustment plate 30 and the a-pillar hinge reinforcement plate 20 are both fixed to the a-pillar reinforcement plate 10, and the installation of the a-pillar hinge reinforcement plate 20 covers the pre-adjustment plate 30, such that the arrangement can enhance the local rigidity and strength of the a-pillar hinge reinforcement plate 20, ensuring the rigidity of the mounting point of the a-pillar hinge reinforcement plate 20. In addition, along the direction of gravity, the hinge reinforcing plate 20 on the A column, the pre-adjusting plate 30 and the A column reinforcing plate 10 are sequentially overlapped, so that the overall strength and rigidity of the vehicle door assembly are further ensured.

Specifically, the a-pillar upper hinge reinforcement plate 20 is spot-welded to the a-pillar reinforcement plate 10.

More specifically, in one embodiment, the a-pillar reinforcement plate 10 includes a plate body 11, the a-pillar hinge reinforcement plate 20 includes a main body portion 21, and the pre-adjustment plate 30 is welded to the plate body 11, and the main body portion 21 is welded to the pre-adjustment plate 30. Referring to fig. 2, it will be appreciated that the pre-adjustment plate 30 is smaller in size than the plate 11, the pre-adjustment plate 30 is welded to the plate 11 of the a-pillar reinforcement plate 10, and then the main body 21 of the a-pillar hinge reinforcement plate 20 is welded to the plate 11, that is, the main body 21 is not welded to the plate 11 in its entirety, but is welded to the plate 11 at a partial interval, so that a gap exists between the main body 21 and the plate 11 to accommodate the pre-adjustment plate 30 without affecting the fixed connection of the main body 21 to the plate 11.

More specifically, in order to increase the local rigidity and strength of the plate body 11 and the main body 21, at least any one of the plate body 11 and the main body 21 is formed with a boss 40, and a clearance groove 41 is formed between the boss 40 and the corresponding plate body 11 or main body 21. It can be appreciated that the clearance groove 41 is a cavity-like structure between the plate body 11 and the main body 21, and the cavity structure can resist the extrusion of external force and absorb certain energy, so that the adoption of the mode of adding the thickness of the plate body 11 and the thickness of the main body 21 to ensure the local rigidity and strength of the plate body 11 and the main body 21 is avoided, thereby achieving the effect of weight reduction and realizing the weight reduction of the vehicle.

The a-pillar reinforcement plate 10 further includes side arms 12 extending from opposite ends of the plate body 11, the a-pillar hinge reinforcement plate 20 further includes a welded edge 22 disposed at an edge of the main body 21, and the a-pillar hinge reinforcement plate 20 is accommodated in the a-pillar reinforcement plate 10 and is opposite to the plate body 11, that is, the a-pillar reinforcement plate 10 has a structure similar to a U-shaped groove formed by the plate body 11 and the side arms 12 extending from opposite ends of the plate body 11, and the a-pillar hinge reinforcement plate 20 is accommodated in the U-shaped groove structure of the a-pillar reinforcement plate 10. Further, the edges of the weld edge 22 are fixed to the side arms 12 by spot welding, it being understood that the a-reinforcement panel 10 may also be configured like a U-shaped channel. In addition, the a reinforcing plate 10 and the a-pillar upper hinge reinforcing plate 20 are integrally formed.

Specifically, the thickness of the A-pillar upper hinge reinforcement plate 20 is in the range of 1 to 1.95mm. It will be appreciated that the thickness of the a-pillar hinge reinforcement plate 20 may be 1mm, 1.2mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 1.95mm, etc., depending on the actual design requirements and the purpose of achieving light weight while also ensuring the rigidity and strength of the a-pillar hinge reinforcement plate 20.

Specifically, the thickness of the pre-adjustment plate 30 is in the range of 2-2.5mm. It will be appreciated that the thickness of the pre-adjustment plate 30 may be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm etc. depending on the actual design requirements and the purpose of achieving light weight while also ensuring the rigidity and strength of the pre-adjustment plate 30.

Specifically, the pre-adjustment plate 30 may also be an a-pillar hinge fixation plate. That is, in some embodiments, the door assembly of the present application further includes an a-pillar hinge securing plate, wherein the a-pillar hinge securing plate is secured between the a-pillar upper hinge reinforcement plate 20 and the a-pillar reinforcement plate 10, with the a-pillar hinge securing plate acting as a pre-adjustment mounting bracket.

More specifically, the door assembly of the present application further includes a securing member (not shown) and a hinge (not shown). And, the preconditioning plate 30, that is, the a-pillar hinge fixing plate is provided with a through hole (not shown), the hinge is provided with a mounting point (not shown), and the fixing member sequentially passes through the mounting point and the through hole and fixes the hinge to the a-pillar hinge fixing plate. It can be appreciated that when the frameless door is assembled with the vehicle body, the frameless door is usually movably connected with the vehicle body through a hinge so as to enable the frameless door to pivot relative to the vehicle body, so that the frameless door is opened and closed, and the problem that the front and rear DTS cannot be controlled easily occurs due to the fact that the frameless door is installed in the near Y direction with the vehicle body, so that repeated adjustment is needed. When the pre-adjusting plate 30 is an a-pillar hinge fixing plate and the a-pillar hinge fixing plate is used as a pre-adjusting mounting bracket, the pre-adjusting plate 30 can realize the X-direction adjustment of the hinge mounting point, and as can be understood, the a-pillar hinge fixing plate is provided with a hole structure such as a through hole or a mounting hole, the hole structure is used for being matched with other components such as a fixing piece, and because the position of the hole structure needs to be aligned with the mounting hole on the hinge, the fixing piece can penetrate through the mounting point of the hinge and the hole structure of the a-pillar hinge fixing plate, so that the hinge is fixed with a vehicle door assembly. It should be noted that the hinge is also called a hinge, and is composed of a movable component or a foldable material.

It should be noted that in the process of installing the frameless door and the vehicle body, a tooling fixture is required, where the tooling fixture refers to a generic term of various tools used in the manufacturing process, including a cutter, a fixture, a mold, a measuring tool, a checking tool, an auxiliary tool, a bench tool, a station tool, and the like, and the tooling fixture includes a fixed end and a movable end. It will be appreciated that in the frameless door mounting process, the a-pillar reinforcing plate 10 is fixed at the fixed end, the pre-adjusting plate 30 is fixed at the movable end, before the pre-welding layers of the a-pillar reinforcing plate 10 and the a-pillar upper hinge reinforcing plate 20 are welded, the number of standard gaskets can be increased or decreased according to the actual positions of the hinge mounting points, so that the movable end moves relative to the fixed end, thereby driving the pre-adjusting plate 30 to move along the X direction, so that the positions of the through hole structures on the pre-adjusting plate 30 (i.e. the a-pillar hinge fixing plate) are aligned with the mounting points of the hinge, thereby determining the welding positions of the pre-adjusting plate 30, avoiding increasing the amount of through holes of the pre-adjusting plate 30, enabling the pressing surfaces of the fixing pieces and the pre-adjusting plate 30 not to be reduced, thereby ensuring the strength and rigidity of the mounting points, and finally, fixing the a-pillar reinforcing plate 10 and the a-pillar upper hinge reinforcing plate 20 by welding, thereby efficiently solving the X direction adjusting problem in the frameless door mounting process, and playing a role in controlling DTS in the assembly process. Note that, DTS (Dimensional Technical Specifications, dimensional specification) generally refers to design criteria of gaps and surface differences between vehicle body parts, and appearance size matching control elements derived from the gaps and the surface differences, such as parallelism, symmetry, alignment, R-angle control, and perceived quality index.
