Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a front passenger armrest mounting bracket and a mounting method. Background Art

[0002] Automobile passenger handrails greatly improve the convenience of getting on the vehicle for some elderly people or people with limited mobility, especially for some high-chassis SUV models; and they play an important role in balancing and stabilizing the vehicle when turning or tilting; general models use two universal small brackets to install the handrails, with a "J"-shaped cross-section, connected to the vehicle body through welds or bolts; there are two problems with the installation of two universal small brackets. First, because the two brackets are universal, the front and rear matching positions of the A-pillar often have to be matched with "bosses" and "recesses", which has a greater impact on the A-pillar cavity; and the A-pillar cavity of the vehicle model is arranged with CBS rubber blocks. This solution not only requires the redevelopment of the CBS rubber blocks, which brings greater cost and cycle impact, but also has a certain negative impact on the roof pressure resistance. Secondly, the universality of the two brackets affects more surrounding arrangements, overturns more previous arrangements, and causes changes to more matching parts.
