Connecting structure for backrest rotating shaft and automobile body of automobile rear-row seat

Abstract

The invention discloses a connecting structure for a backrest rotating shaft and an automobile body of an automobile rear-row seat. The connecting structure comprises a backrest framework and the automobile body connected with the backrest framework. A spring rotating shaft is arranged on one side of the backrest framework, and a spring rotating shaft mounting metal plate matched with the spring rotating shaft is arranged at the position, corresponding to the spring rotating shaft, of the automobile body; a step rotating shaft is arranged on the other side of the backrest framework, and a step rotating shaft installation support assembly matched with the step rotating shaft is arranged at the position, corresponding to the step rotating shaft, of the vehicle body. The seat backrests are installed independently and do not influence each other, the whole assembly process is simple and convenient, the manufacturing tolerance of the seat and a vehicle body is absorbed through the spring rotating shafts, meanwhile, force is applied to the seat backrests for restraining, the abnormal sound problem of the seat backrest rotating shafts due to up-down jumping and left-right shaking of the seat can be effectively avoided, and the service life of the seat is prolonged. And the seat has excellent quality performance.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a connection structure between a backrest rotating shaft of an automobile rear seat and a vehicle body. Background technique [0002] At present, with the increasingly fierce competition in the automobile market, various automobile manufacturers have stricter control over the quality of the vehicle, and the quality and performance of the seats are the first to bear the brunt. For the rear seat of the car whose backrest can be turned over, the backrest shaft usually adopts a pin-type shaft mechanism. Due to the clearance fit of the hole shaft, after the backrest is overturned, the backrest will jump when the car is running on a rough road. , Abnormal noise is likely to occur at the backrest shaft. In addition, due to the limitation of installation space, the traditional bolt-type assembly makes it difficult to install the backrest. Most of them can only be inst...

Problems solved by technology

For the rear seat of the car whose backrest can be turned over, the backrest shaft usually adopts a pin-type shaft mechanism. Due to the clearance fit of the hole shaft, after the backrest is overturned, the backrest will jump when the car is running on a rough road. , Abnormal noise is likely to occur at the hinge of the backrest

In addition, due to the limitation of installation space, the traditional bolt-type assembly makes it difficult to install the backrest. Most of them can only be installed by squeezing the backrest or using robots, which is extremely inconvenient for manual installation.
