SUSPENSION SYSTEM FOR ABSORBING A SHOCK LOAD AND STROLLER THEREWITH

摘要

A suspension system includes a main pivot housing, a swing arm housing, a linkage assembly, and a resilient component. The main pivot housing is disposed on a lower end of a leg of a stroller. An accommodating space is formed inside the main pivot housing. The swing arm housing is pivoted to a side of the main pivot housing. A wheel of the stroller is pivoted to the swing arm housing. The linkage assembly is movably disposed in the accommodating space. The resilient component is disposed between the linkage assembly and a bracket of the stroller. The swing arm housing can be forced to drive the linkage assembly to pivot relative to the main pivot housing for compressing the resilient component, so as to absorb a shock load.

1. A suspension system adapted for a leg of a stroller and for absorbing a shock load, the suspension system comprising:
a main pivot housing disposed on a lower end of the leg of the stroller, an accommodating space being formed inside the main pivot housing; at least one swing arm housing pivoted to at least one side of the main pivot housing, a wheel of the stroller being pivoted to the at least one swing arm housing; a linkage assembly movably disposed in the accommodating space, an end of the linkage assembly being pivoted to the main pivot housing and installed on the at least one swing arm housing, and another end of the linkage assembly being pivoted to the at least one swing arm housing and slidably installed on the main pivot housing; and a resilient component, an end of the resilient component being pivoted to the other end of the linkage assembly, and the other end of the resilient component being coupled to a bracket between the leg and a bottom tube of the stroller; wherein when the at least one swing arm housing rotates relative to the main pivot housing, the at least one swing arm housing drives the linkage assembly to pivot relative to the main pivot housing, so that the resilient component is compressed by the linkage assembly to absorb the shock load.
