US 8,262,107 B2 · Stroller and related vibration-absorbing mechanism

Abstract

A stroller includes a chassis, a main body disposed on the chassis, and a first vibration-absorbing mechanism including a first rod structure, a first sleeve structure, a first inner elastic part, and a first outer elastic part. The first rod structure is connected to a side of the chassis. The first sleeve structure is connected to the main body and movably sleeves the first rod structure. The first inner elastic part abuts against the first rod structure and the first sleeve structure. When the first vibration-absorbing mechanism is in a first use state, the first outer elastic part is in contact with one of the first sleeve structure and the first rod structure. When the first rod structure slides toward the first sleeve structure over a specific distance, two ends of the first outer elastic part abut against the first sleeve structure and the first rod structure, respectively.

A vibration-absorbing mechanism for a stroller, the stroller comprising a chassis and a main body disposed on the chassis, the vibration-absorbing mechanism comprising:

a rod structure connected to a side of the chassis;
a sleeve structure connected to the main body and movably sleeving the rod structure;
an inner elastic part abutting against the rod structure and the sleeve structure respectively;
and
an outer elastic part disposed around the inner elastic part and located between the sleeve structure and the rod structure;
wherein when the vibration-absorbing mechanism is in a first use state, the outer elastic part is in contact with one of the sleeve structure and the rod structure;
when the rod structure slides toward the sleeve structure over a specific distance, the vibration-absorbing mechanism switches from the first use state to a second use state, and two ends of the outer elastic part abut against the sleeve structure and the rod structure respectively.
