Rear-row seat lock catch mounting structure and mounting method thereof

Abstract

The invention discloses a rear-row seat lock catch mounting structure and a mounting method thereof. The rear-row seat lock catch mounting structure comprises a rear wheel cover outer plate and a rear-row seat lock catch; a rear-row seat lock catch mounting bracket is welded on the rear wheel cover outer plate; a C-pillar upright post reinforcing plate is welded on the other side opposite to the rear-row seat lock catch mounting bracket; a first mounting hole and a welding nut corresponding to the rear-row seat lock catch are arranged on the rear-row seat lock catch mounting bracket; a secondmounting hole corresponding to the first mounting hole is formed in the end part of one side, opposite to the rear-row seat lock catch mounting bracket, of the rear-row seat lock catch, and the firstmounting hole and the second mounting hole are oppositely attached and are provided with bolts for screwing the rear-row seat lock catch and the rear-row seat lock catch mounting bracket together. Thestructure is simple, the single-piece forming rate is effectively improved, the size is small, optimization of the space in the vehicle is facilitated, useful space is provided for layout of other devices, the cost is low, and the cost of the whole vehicle is further reduced.

Description

Technical field: [0001] The invention relates to a rear seat lock buckle installation structure and an installation method thereof, belonging to the technical field of automobiles. Background technique: [0002] At present, the rear seats of passenger cars are all designed as a flip structure, and there are two ways to lock and fix the rear seats: the first is that the seat comes with an angle adjuster; the second is to rely on the lock to lock and fix. Among them, the self-contained angle adjuster is costly and heavy, and requires high technology for the seat. In the traditional seat lock installation method, the seat lock is connected to the wheel house support plate by adding parts, and the wheel house support plate is connected to the floor beam, so that the force of the seat will be transmitted to the wheel house floor, and are scattered to improve structural stability, but this structure has too many layers of welding, which is likely to cause matching difficulties, a...

AI Technical Summary

Problems solved by technology

Among them, the built-in angle adjuster is costly and heavy, and the process requirements for the seat are relatively high

In the traditional seat lock installation method, the seat lock is connected to the wheel house support plate by adding parts, and the wheel house support plate is connected to the floor beam, so that the force of the seat will be transmitted to the wheel house floor, and are scattered to improve structural stability, but this structure has too many layers of welding, which is likely to cause matching difficulties, and has high requirements for welding operations. The overall structure volume and weight are large, resulting in an increase in vehicle weight. The space is reduced, and the layout of various parts in the car is limited, which cannot meet the requirements of light weight of the car body and optimization of the space layout in the car.
