Abstract
The disclosure relates to a rear roof cross beam mounting structure for a vehicle, and a vehicle. The rear roof cross beam mounting structure comprises: a left D pillar and a right D pillar, the left D pillar and the right D pillar each being fixed to a body of the vehicle; a lower cross beam, the lower cross beam being arranged between the left D pillar and the right D pillar; and a pre-positioning structure, the pre-positioning structure comprising pre-positioning posts and pre-positioning holes, wherein the pre-positioning posts are columnar protrusions respectively extend upwardly from bodies of the left D pillar and the right D pillar along a center line offset from a Z-direction of the vehicle by a predetermined acute angle, the pre-positioning holes are U-shaped grooves respectively formed in a left side edge and a right side edge of the lower cross beam and having openings facing away from a body of the lower cross beam, and the columnar protrusions are configured to be insertable into corresponding U-shaped grooves such that the lower cross beam can be placed on each of the left D pillar and the right D pillar along the center line. The vehicle of the disclosure can efficiently achieve pre-positioning fit, the assembly takt can be optimized, and the assembly efficiency can be increased.
Claims
