Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] figure 1 It is the installation structure of the existing third row of seats, including the rear floor 1, the left longitudinal beam 21 and the right longitudinal beam 22 positioned and connected under the rear floor, the rear crossbeam 3 and the third row of seats connected to the rear floor Three-row seat front beam 4. With this structure, the strength of the installation part of the third row of seats is low, which cannot meet the requirements for supporting the third row of seats and the occupants, and is not conducive to improving the overall NVH performance of the vehicle body.
[0030] see Figure 2 to Figure 11 According to the present invention, the installation and fixing structure of the third row of seats of the automobile includes the left longitudinal beam 21 and the right longitudinal beam 22 positioned and connected under the rear floor 1, and ...

The invention relates to a mounting and fixing structure of a car third-row seat. The mounting and fixing structure comprises a left longitudinal beam and a right longitudinal beam connected below a rear floor and is characterized in that a third-row seat left reinforcing longitudinal beam with an 'n'-shaped section is connected above the rear floor and corresponds to the left longitudinal beam; a third-row seat right reinforcing longitudinal beam with an 'n'-shaped section is connected above the rear floor and corresponds to the right longitudinal beam; a left mounting support of the third-row seat is connected to the front portion of the third-row seat left reinforcing longitudinal beam, and a right mounting support of the third-row seat is connected to the front portion of the third-row seat right reinforcing longitudinal beam; a third-row crossbeam component is connected between the upper surfaces of the middle portion of the third-row seat left reinforcing longitudinal beam and the third-row seat right reinforcing longitudinal beam. By the mounting and fixing structure, the strength and rigidity of the part, for mounting the third-row seat, of the rear floor can be increased evidently, the requirements for supporting the third-row seat and passengers are satisfied, and the overall NVH performance of a car body is improved.
Description
technical field [0001] The invention relates to a fixing structure of an automobile accessory, in particular to a fixing structure for installing and fixing a third row of seats of an automobile. Background technique [0002] At present, in the development process of large commercial vehicles or large SUVs (the full name of SUV is Sport Utility Vehicle, which means sports utility vehicles in Chinese), some models have added the configuration of the third row of seats to meet market demand. The third row of seats is generally divided into integral type and split type. The installation and fixing structure of the third row of seats is generally composed of front and rear beams, and the installation reinforcement plates of the seats are welded on the beams. As disclosed in CN201914317U "a mounting beam structure for fixing the third row of seats in a car", it solves the technical problem that the existing car cannot be installed with the third row of seats in the car. The moun...
