Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle body structure, and more specifically, it relates to a novel charging seat installation and surrounding connection structure. Background Technology
[0002] The charging dock mounting reinforcement structure is located on the left or right side of the vehicle body. Its main function is to provide a mounting point for the charging dock, and at the same time, it provides sufficient support strength to the side panel through its own structure, thereby strengthening the overall strength of the vehicle body and improving the side panel's resistance to dents. There are two main types of existing charging dock mounting reinforcement structures. One type is directly mounted on the outer panel of the wheel arch, and the other type uses two sets of mounting brackets. The first set of mounting brackets is first welded to the outer panel of the wheel arch, and the second set of charging port brackets is welded to the first set of mounting brackets for mounting the charging dock.
[0003] Structure 1, which is directly mounted on the outer panel of the wheel arch, has weak structural strength and body strength, which is not conducive to improving the side wall's dent resistance. Structure 2 has a complex structure with many parts, resulting in high unit cost, mold cost, and welding cost. The existing two structures are connected to the wheel arch in a single way, resulting in a weak overall structure. To improve the overall strength of the side wall, an additional side wall connecting bracket is needed to connect to other surrounding structural components. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a new type of charging seat installation and surrounding overlapping structure. By overlapping and fixing the charging seat installation bracket with the D-pillar, wheel cover plate and window frame inner plate to form an integral structure, the charging seat is guaranteed to have sufficient installation strength after installation, while improving the side wall's resistance to dents.
[0005] The novel charging base mounting and peripheral connection structure includes a charging base mounting bracket. A window frame inner panel is fixedly mounted on the upper end of the charging base mounting bracket. A D-pillar is fixedly mounted on the right end of the charging base mounting bracket. A wheel cover plate is fixedly mounted on the lower end of the charging base mounting bracket. Multiple sets of charging base mounting holes and actuator snap-fit holes are fixedly opened in the middle of the charging base mounting bracket. A connecting plate is fixedly mounted on the top of the charging base mounting bracket, and wire harness snap-fit holes are fixedly opened on the connecting plate. Two sets of wire harness holes are fixedly opened on the upper left side of the charging base mounting bracket. A connecting pin extends backward from the left side of the charging base mounting bracket and is welded and fixed to the wheel cover plate. A wire harness through hole is fixedly opened at the lower part of the charging base mounting bracket. A bent arc plate extends forward from the bottom of the charging base mounting bracket. A connecting pin extends backward from the right side of the charging base mounting bracket.
[0006] Preferably, positioning holes are fixedly provided on the upper left side and bottom of the charging dock mounting bracket.
[0007] Preferably, the connecting plate has a second connecting pin extending rearward on the right side, which is welded and fixed to the D-pillar. An avoidance groove is fixedly opened in the middle of the connecting plate, and the connecting plate is welded and fixed to the inner plate of the window frame.
[0008] Preferably, the connecting pin three is fixedly provided with a bent plate reinforcing rib, and the connecting pin three is also fixedly provided with a relief groove two, and the connecting pin three is welded and fixed to the bottom of the D column.
[0009] Preferably, the bent arc plate is provided with multiple sets of protrusions, and a folded plate extends backward from the right side of the bent arc plate. The bent arc plate is welded and fixed to the wheel cover plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By overlapping and fixing the charging base mounting bracket with the D-pillar, wheel arch plate and window frame inner panel to form an integral structure, the charging base is guaranteed to have sufficient installation strength after installation, while improving the side wall's resistance to dents. 2. Both the connecting pin 1 and the bent arc plate are welded and fixed to the wheel cover plate, which expands the welding area between the charging base mounting bracket and the wheel cover plate and improves the connection strength between the charging base mounting bracket and the wheel cover plate. 3. By setting multiple sets of protrusions on the bent arc plate, the full fit between the bent arc plate and the wheel cover plate is ensured, and the structural strength of the bent arc plate itself is also improved. By setting the folding plate, the welding area between the charging seat mounting bracket and the wheel cover plate is further increased, ensuring the connection strength. Attached Figure Description

An avoidance groove 602 is fixedly provided in the middle of the connecting plate 6. The connecting plate 6 is welded and fixed to the inner panel 1 of the window frame. By setting the avoidance groove 602, interference with the bolt holes on the inner panel 1 of the window frame is avoided.
[0019] A bent plate reinforcing rib 1201 is fixedly provided on the connecting pin 3 12, and a relief groove 2 1202 is also fixedly provided on the connecting pin 3 12. The connecting pin 3 12 is welded and fixed to the bottom of the D-pillar 2. By setting the relief groove 2 1202, interference with the bolt holes on the D-pillar 2 is avoided, and by setting the bent plate reinforcing rib 1201, the structural strength of the connecting pin 3 12 is improved.
[0020] The bent arc plate 13 has multiple sets of protrusions, and a folding plate 1301 extends rearward from the right side of the bent arc plate 13. The bent arc plate 13 is welded and fixed to the wheel cover plate 3. By setting multiple sets of protrusions on the bent arc plate 13, the full fit between the bent arc plate 13 and the wheel cover plate 3 is ensured, and the structural strength of the bent arc plate 13 itself is also improved. By setting the folding plate 1301, the welding area between the charging seat mounting bracket 4 and the wheel cover plate 3 is further increased, ensuring the connection strength.
