Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to a right front pillar outer plate reinforcement plate assembly. Background Art

[0002] The outer reinforcement plate assembly of the right front pillar of a car is a metal plate installed on the outside of the car pillar. Its main function is to enhance the rigidity and strength of the pillar, thereby improving the overall stability and collision resistance of the car body.

[0003] When a car collides, the reinforcement plate can effectively reduce the damage caused by the impact force to the occupants and improve the safety of the occupants. The hinges of the door are also installed on the reinforcement plate, which places high requirements on the supporting strength and stability of the reinforcement plate.

[0004] The current right front pillar outer reinforcement plate assembly is usually composed of a main support plate at the bottom and an extension rod connected to the upper part. The two are usually connected by welding and do not have a structure that limits and supports each other. Therefore, after being subjected to severe impact force, they are prone to desoldering and separation from each other, which is not conducive to ensuring the collision support strength. In addition, during the driving of the car, the chassis noise and the wind noise from the upper part will be transmitted into the cab along the reinforcement plate, resulting in relatively large wind noise, which needs further optimization and improvement.

DETAILED DESCRIPTION

[0024] Example 1, see the attached specification Figure 1-3 6. A right front pillar outer panel reinforcement plate assembly, including a hinge support plate 01 and a channel steel-shaped plate body 02. A connecting section A 11 with a triangular groove-shaped cross section is provided at the upper end of the hinge support plate 01, and a connecting section B 21 is provided at the lower end of the channel steel-shaped plate body 02. The connecting section B 21 is fitted and fixed into the connecting section A 11. The hinge support plate 01 and the channel steel-shaped plate body 02 are fitted and connected and welded together through the two connecting sections. An upper hinge reinforcement plate 03 is matched and installed in the groove body at the upper part of the hinge support plate 01. The upper hinge reinforcement plate 03 is used to install the upper hinge of the vehicle door. A lower hinge reinforcement plate 04 is matched and installed in the groove body at the lower part. The lower hinge reinforcement plate 04 is used to install the lower hinge of the vehicle door, and a lower reinforcement bracket 61 is provided in the hinge support plate 01 at the lower part of the lower hinge reinforcement plate 04.

[0025] A V-shaped transition groove 12 is provided between the connecting section A 11 and the hinge support plate 01, and a V-shaped joint 211 is provided at the outer end of the connecting section B 21. The V-shaped joint 211 is matched and inserted into the V-shaped transition groove 12, and the V-shaped transition groove 12 and the V-shaped joint 211 form a limited support structure. The cross-sectional dimension of the connecting section B 21 is smaller than the cross-sectional dimension of the channel steel-shaped plate body 02, and ear plates 212 are provided at the edges of both sides of the connecting section B 21, and the ear plates 212 are fixedly attached to the upper edge of the connecting section A 11.

[0026] The upper hinge reinforcement plate 03 is a square box body as a whole, with long holes 31 on both sides of the square box body, and vertical folded edges 32 on the edges of the square box body. The square box body has excellent shock absorption performance and reinforcement support performance, which ensures the stability of the door hinge after connection, and the vertical folded edges 32 of the square box can assist in connecting the upper hinge reinforcement plate 03 with the vehicle body. The lower hinge reinforcement plate 04 is a plate body with flanges on all sides. The upper hinge reinforcement plate 03 and the lower hinge reinforcement plate 04 are both welded and fixed in the hinge support plate 01. The flanges can increase the anti-deformation support strength of the lower hinge reinforcement plate 04 itself, and can increase its fitting area with the side of the upper hinge reinforcement plate 03, making it more stable.

[0027] The reinforcing plate assembly of this embodiment is provided with mutually matching V-shaped transition grooves 12 and V-shaped joints 211 at the welding points between the hinge support plate 01 and the channel steel-like plate body 02. After the two are sleeved together, a V-shaped limiting support structure is formed, which improves the firmness of the connection between the two after welding, and effectively improves the connection strength and support strength of the reinforcing plate assembly.

[0028] Example 2, see the attached specification Figure 4-5 On the basis of the first embodiment, a lower sound insulation board 05 is provided on one side of the lower hinge reinforcement board 04, and an upper sound insulation board 06 is provided on the lower part of the channel steel plate body 02.

[0029] The lower sound insulation board 05 is configured as an isosceles trapezoid as a whole, including a board body A 51 and a board body B 52. Two seat plates 511 are arranged side by side on the bottom surface of the board body A 51. The bottom surface of the seat plate 511 is provided with an elastic clamp 512. A clamping hole 55 is provided at the corresponding position of the hinge support plate 01. The elastic clamp 512 is clamped into the clamping hole 55. The installation direction of the lower sound insulation board 05 coincides with the cross section of the hinge support plate 01, and the internal cavity is completely closed. The sound insulation board mainly plays the role of blocking the transmission of sound, and does not play the role of reinforcement and support. The elastic clamp 512 is provided to facilitate assembly and connection, and ensure that the sound insulation board is stably connected to the hinge support plate 01. A groove portion 514 is provided in the middle of the surface of the plate body A 51, and a through hole is provided in the middle of the plate body B 52. The groove portion 514 is inserted into the through hole with a gap between the two. The gap forms an annular groove 53 between the plate body A 51 and the plate body B 52. The annular groove 53 formed by the combination of the two plate bodies and the groove portion 514 on the plate body A 51 can absorb noise, and the effect of blocking noise transmission is better.

[0030] A number of snap-fit ​​assemblies 54 are evenly arranged between the edge portions of the plate body A 51 and the plate body B 52, and the plate body A 51 and the plate body B 52 are fixedly connected by the snap-fit ​​assemblies 54. Vertical ribs 513 are arranged between the seat plate 511 and the plate body A 51, and the middle vertical ribs 513 extend upward to the middle of the groove portion 514. After assembly, the seat plate 511 fits with the inner surface of the hinge support plate 01 to form a leg support structure, which can improve the connection strength of the elastic clamp 512 in the clamping hole 55, and the vertical ribs 513 can improve the stability of the connection of the seat plate 511.

[0031] The shape of the upper sound insulation board 06 is generally triangular. The structure of the upper sound insulation board 06 is the same as that of the lower sound insulation board 05. It is connected to the channel steel plate body 02 through an elastic clamp 512. The upper sound insulation board 06 is used to block the sound transmission from the roof and windows of the vehicle, thereby reducing the amount of noise transmitted to the cab.
