Specifically, as shown in fig. 2, "inside of the quarter panel 10" refers to a side of the quarter panel 10 adjacent to the vehicle interior, that is, a side of the quarter panel 10 mounted to the B-pillar reinforcement panel 20 away from the vehicle interior, and in the following description of the present specification, "inner" and "outer" both refer to relative to the vehicle interior. A pre-installation region is provided at a side surface of the B-pillar reinforcement plate 20 located inside the outer cavity 20a, a positioning portion 21 is provided at the pre-installation region, and an outer soundproof block 40 is installed at the positioning portion 21, wherein the outer soundproof block 40 may be made of a foamed material, and the outer soundproof block 40 is expanded under a high temperature condition to fill the outer cavity 20 a.
The assembly process of the B-pillar 100 will be described, in which the outer soundproof block 40 is first installed at the positioning portion 21 of the B-pillar reinforcing plate 20, then the quarter outer panel 10 is installed outside the B-pillar reinforcing plate 20 to define an outer cavity 20a between the quarter outer panel 10 and the B-pillar reinforcing plate 20, and then the B-pillar 100 is painted and baked to expand the outer soundproof block 40 to block the lower portion of the outer cavity 20 a. Preferably, the B-pillar stiffener 20 may employ a hot forming process to secure the strength of the B-pillar stiffener 20, thereby improving the side collision prevention capability of the B-pillar 100.
It should be noted that, the specific position of the pre-installation area on the B-pillar 100 is not limited in the present invention, and those skilled in the art can determine the position of the pre-installation area according to experiments or experience as long as the condition that the outer sound insulation block 40 is filled with the outer cavity 20a after being expanded is satisfied.
According to the utility model discloses B post 100, carry out prepositioning to outer puigging block 40 through set up location portion 21 on B post reinforcing plate 20, when outer puigging block 40 of artifical installation, the staff's of being convenient for discernment is the installing zone in advance, thereby improve the location precision of outer puigging block 40 in installing zone department in advance, avoided outer puigging block 40 to cause outer puigging block 40 to fill out the condition that is full of exocoel 20a through the inflation after the location emergence deviation of installing zone department in advance, consequently, according to the utility model discloses B post 100 can improve the position precision when outer puigging block 40 installs, fill out exocoel 20a after guaranteeing that outer puigging block 40 is through the inflation, thereby improved the NVH performance of vehicle (noise, vibration and acoustic vibration roughness promptly), and then reached the purpose of making an uproar, improved the riding comfort of vehicle.
In some embodiments of the present invention, as shown in fig. 1, the positioning portion 21 includes a plurality of positioning holes 211, and each positioning hole 211 penetrates the B-pillar reinforcement plate 20 in the thickness direction of the B-pillar reinforcement plate 20.
