AI Technical Summary
In the existing technology, the car seat frame is welded to the car body floor as one piece, which makes the weld points easy to deform during a collision. During repair, the old weld points need to be cut and re-welded, causing secondary damage to the car body floor. This technology has poor flexibility and cannot be flexibly replaced or upgraded according to user needs or changes in vehicle configuration.
The seat frame is connected to the vehicle floor via detachable mounting units, using mounting bolts and support sleeves. This eliminates the need for welding and allows for a detachable connection between the seat frame and the vehicle floor, enhancing flexibility and ease of maintenance.
It enables flexible replacement and upgrading of the seat frame, reduces secondary damage during maintenance, improves maintenance convenience and economy, and enhances collision safety performance.
