The invention relates to a car seat shock absorber chamber spring device. The car seat shock absorber chamber spring device comprises a seat plate at the upper part and groove blocks at the lower part, wherein two chamber springs are arranged between the seat plate and the groove blocks, each chamber spring is provided with an upper cover and a lower cover which are buckled together, a spring is arranged in a chamber jointly formed by the upper cover and the lower cover, the upper end of the upper cover is slidably connected with the seat plate, the lower end of the lower cover is rotatably connected with the corresponding groove block and the two chamber springs are separated and arranged in parallel. Since the chamber springs need air to come in and go out from gaps during compression and release, certain time is needed during air incoming and outgoing and the vibrating frequency of the chamber springs is not decided only by the property of the springs therein due to the air pressure in the chambers but is decided by the two aspects of air pressure and spring property, unfixed frequency can be obtained again through coupling between the chamber springs and springs connected with low plug caps below the chamber springs, the vibrating frequency is slowed down, resonance is not caused and long-lasting uncomfortable vibrating frequency is not caused to human bodies.
