Document Type and Number:
WIPO Patent Application WO/2020/063670
Kind Code:
A1
Abstract:
Disclosed are a main bicycle frame (100) for a foldable bicycle and a foldable bicycle (500). The main bicycle frame comprises a connection tube member (11), an upper tube member (12), a lower tube (20), first and second hinge lock catches (15, 16), and a handle (17). The upper tube member (12) is mounted to the connection tube member (11), and the connection tube member (11) can be unfolded or folded relative to the upper tube member (12). The lower tube (20) is mounted to the upper tube member (12), and the lower tube (20) can be unfolded or folded relative to the upper tube member (12). The first hinge lock catch (15) is mounted to the upper tube member (12) and is used for locking the connection tube member (11) when the connection tube member (11) is unfolded relative to the upper tube member (12). The second hinge lock catch (16) is mounted to the upper tube member (12) and is used for locking the lower tube (20) when the lower tube (20) is unfolded relative to the upper tube member (12). The handle (17) connects the first and second hinge lock catches (15, 16), and when the first hinge lock catch (15) locks the connection tube member (11) and the second hinge lock catch (16) locks the lower tube (20), the handle (17) drives both of the first and second hinge lock catches (15, 16) to unlock, so that both the connection tube member (11) and the lower tube (20) can be folded relative to the upper tube member (12). In this way, one action can complete the unlocking of the first and second hinge lock catches (15, 16) at the same time, and can rapidly complete a folding operation of a foldable bicycle (500).
