Document Type and Number:
WIPO Patent Application WO/2018/076275
Kind Code:
A1
Abstract:
Disclosed are an inflation valve cap, an inflation valve structure, and a tyre and a vehicle. The inflation valve cap comprises: a main body structure (1), a push rod structure, an elastic restoring member (4) and a push rod fixing base (6). The interior of the main body structure (1) is provided with a central cavity running from top to bottom along a central axis thereof. The push rod structure is disposed inside the central cavity, and can slide up and down along the central cavity, the upper end of the push rod seals an upper end opening of the central cavity, and the lower end thereof is located inside an inner cavity of the push rod fixing base (6). The elastic restoring member (4) is arranged between the upper end of the push rod structure and the push rod fixing base (6). The push rod fixing base (6) is located at a lower portion of the central cavity, and a middle portion of the inner cavity of the push rod fixing base is gradually expanding from top to bottom. A bottom portion of the push rod structure is provided with a push rod seal (5), and in a non-inflated state, the push rod seal (5) presses against an inner inclined face at the middle portion of the inner cavity of the push rod fixing base (6), thereby achieving the sealing in the non-inflated state, preventing the deposition of dust on the push rod fixing base (6), and avoiding the accumulation of dust.
