Automobile seat cushion framework structure

Abstract

The invention discloses an automobile seat cushion framework structure. The automobile seat cushion framework structure comprises a U-shaped seat cushion frame, and multiple pairs of spring fixing parts are sequentially and symmetrically arranged on two U-shaped arms of the U-shaped seat cushion frame at intervals. Each spring fixing part comprises a clamping hole and a spring positioning hole, wherein the clamping hole can clamp the corresponding U-shaped arm in a sleeved mode, and the spring positioning hole can be hooked by a spring. One serpentine spring is arranged between each pair of spring fixing parts, the two ends of each serpentine spring are hooked in the spring positioning holes of the corresponding spring fixing parts on the two sides, and each spring fixing part and the U-shaped arm clamped by the spring fixing part in a sleeved mode are fixedly limited through a limiting mechanism. The automobile seat cushion framework structure has the advantages of being convenient to install and maintain and high in enterprise productivity.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile seat cushion skeleton structure. Background technique [0002] The car cushion frame is an indispensable safety component in the car. The structure of the car seat frame currently used is: including a U-shaped cushion frame, which is symmetrically arranged on the two U-shaped arms of the U-shaped cushion frame from front to back. There are several pairs of S-shaped weldments, each S-shaped weldment is clamped on the corresponding U-shaped arm through its lower bayonet, and is welded and fixed with the U-shaped arm, and each pair of S-shaped welded pieces is respectively arranged There is a serpentine spring, and the two ends of each serpentine spring are respectively hooked on the upper bayonets of the S-shaped weldments on both sides. The disadvantage of this cushion skeleton structure is: when installing each S-shaped weldment in the cushion skeleton, the lower bayonet...

AI Technical Summary

Problems solved by technology

The disadvantage of this cushion skeleton structure is: when installing each S-shaped weldment in the cushion skeleton, the lower bayonet of the S-shaped weldment needs to be manually clamped on the U-shaped arm of the U-shaped cushion frame and supported. , and then use a welding torch to weld the lower part of the S-shaped welded piece to the U-shaped arm of the U-shaped cushion frame. Each S-shaped welded piece needs to weld at least 3 welding points to ensure that the car seat cushion frame with serpentine springs It will not sink or even fall off during use. This kind of cushion skeleton structure is not only cumbersome to disassemble and maintain, but also has high labor intensity for workers and low production efficiency for enterprises.
