[0002] Commercial vehicles evolved from station wagons. They integrate functions such as the spacious passenger space of station wagons and the comfort of sedans. Commercial vehicles generally use sedan chassis, so they have a comfortable feeling similar to sedans. When commercial vehicles are used in some other places, they need to have good sound - proof and buffer performance so that they can isolate external noises.

[0003] After retrieval, the authorized announcement number CN220096105U discloses a flexible sound - proof and buffer structure for a commercial vehicle, which relates to the technical field of commercial vehicles. It includes a first slide rail and a second slide rail. A sliding door is slidably connected to the surface of the first slide rail. A connecting plate is fixedly connected to the surface of the sliding door. A fixed clamping rod is fixedly connected to the surface of the connecting plate. A chute is opened inside the second slide rail. A movable clamping rod is slidably connected inside the chute. A moving plate is fixedly connected to the surface of the movable clamping rod. The advantages of the utility model are as follows: when pulling to open the sliding door, the sliding door drives the fixed clamping rod on the connecting plate to move along the second slide rail. During the movement, the fixed clamping rod squeezes the movable clamping rod to retract and compress the first spring until the fixed clamping rod passes over the movable clamping rod. The first spring pushes the movable clamping rod to reset to limit the fixed clamping rod and the sliding door, separating the buffer and shock - absorption component from the limiting component to avoid damaging the buffer and shock - absorption component.
