Description

Technical Field

[0001] The utility model belongs to the field of automobile door components, and in particular relates to a frameless door hinge reinforcement component assembly, a frameless door and an automobile. Background Art

[0002] CN216231968U discloses an exterior rearview mirror installation assembly, a vehicle door and a vehicle, which includes a door inner panel, a hinge reinforcement plate, an outer waistline reinforcement plate, a reinforcement member and a window guide rail (i.e., a glass lifting slide groove). The door inner panel, the hinge reinforcement plate and the outer waistline reinforcement plate are welded to form a rearview mirror installation structure, and the window guide rail is welded to the hinge reinforcement plate and the reinforcement member to form a window glass slide groove. This structure has the following problems: (1) In addition to being spot-welded to the hinge reinforcement plate and the door inner panel, the reinforcement member also needs to be spot-welded to the window guide rail and the outer waistline reinforcement plate. This transverse connection structure is a closed dimension chain structure design, which requires extremely high dimensional accuracy of the reinforcement member, hinge reinforcement plate, window guide rail and outer waistline reinforcement plate, and the welding accuracy is difficult to ensure. (2) The window rail is designed with a process avoidance punching groove (i.e., lifting groove) at the connection part where it is spot welded with the hinge reinforcement plate. This groove will reduce the structural strength of the window rail parts, reduce the clamping strength of the glass, and increase the risk of glass shaking. In addition, because the window rail has a process avoidance punching groove, the surface of the window rail is no longer continuous during the glass lifting process, increasing the risk of glass shaking during the lifting process. (3) The rearview mirror installation area of ​​the door inner panel is a triangular area higher than the water tangent line of the door inner panel. This triangular area is connected to the rearview mirror installation area of ​​the hinge reinforcement plate through a two-layer spot welding process to increase the structural strength and meet the requirements of the rearview mirror for the installation point strength and mode of the installation area. However, it will cause the cutting size of the rearview mirror installation area of ​​the door inner panel to be much larger than the cutting size of the water tangent line of the door inner panel, resulting in low material utilization and easy material waste.

[0028] It should also be pointed out that the terms "first\second\third\fourth\fifth\sixth" involved in the embodiments of the present invention are only used to distinguish similar objects and do not represent a specific ordering of the objects.

[0029] like Figures 1 to 8 As shown, the frameless door hinge reinforcement assembly in the embodiment of the utility model includes a front door hinge reinforcement 11, a front door upper corner plate 12, a glass lifting slide 13 and a slide bracket 14. The front door upper corner plate 12 is welded to the upper part of the front door hinge reinforcement 11, the slide bracket 14 is welded to the lower part of the glass lifting slide 13, the glass lifting slide 13 is welded to the front door upper corner plate 12, and the slide bracket 14 is welded to the front door hinge reinforcement 11 to form a closed frame structure. As an example, the welding described here is spot welding.

[0030] In some embodiments, the upper portion of the front door hinge reinforcement 11 has a reinforcement first welding area 111, a reinforcement second welding area 112, and a reinforcement third welding area 113. The upper portion of the front door upper corner plate 12 has an upper corner plate first welding area 121, an upper corner plate second welding area 122, and the lower portion of the front door upper corner plate 12 has an upper corner plate third welding area 123.

As an example, the welding described here is spot welding.

[0031] In some embodiments, the upper portion of the front door hinge reinforcement 11 also has a reinforcement fourth welding area 114, and the left side of the front door upper corner plate 12 has a reinforcement flange 126, and the reinforcement flange 126 has the upper corner plate fourth welding area 124 and the upper corner plate fifth welding area 125, and the upper corner plate fourth welding area 124 and the upper corner plate fifth welding area 125 are welded to the reinforcement fourth welding area 114. As an example, the welding described here is spot welding. The reinforcement flange 126 increases the strength of the front door upper corner plate 12, and at the same time, the upper corner plate fourth welding area 124 and the upper corner plate fifth welding area 125 are welded to the reinforcement fourth welding area 114, which further enhances the installation point strength and mode of the rearview mirror installation area without increasing the thickness of the part material.

[0032] In some embodiments, the right side of the front door upper corner plate 12 has an upper corner plate sixth welding area 127, and the outer side wall of the glass lifting and lowering slide 13 is welded to the upper corner plate sixth welding area 127.

The two welding avoidance holes 128 are designed to facilitate the welding of the front door hinge reinforcement 11, the front door inner panel 2, and the reinforcement 3 on the inner panel, avoiding the need to open a process avoidance punching groove on the glass lifting and lowering slide 13 to meet the welding process requirements. The overall strength of the glass lifting and lowering slide 13 is better, which is conducive to improving the clamping effect of the glass and reducing the risk of glass shaking during the closing and opening of the door. In addition, the continuous profile of the glass lifting and lowering slide 13 ensures that the glass lifting and lowering trajectory is also continuous, reducing the risk of glass shaking during the lifting and lowering process.

As an example, the welding described here is spot welding. The water tangent line 21 of the front door inner panel 2 is flush with the upper edge 22 of the rearview mirror installation area of ​​the front door inner panel 2, and the front door inner panel 2 no longer has a triangular area. From the perspective of product design, the blanking size of the front door inner panel 2 is reduced, the material utilization rate is improved, and the material cost of the whole vehicle is reduced.
