Document Type and Number:
WIPO Patent Application WO/2017/186131
Kind Code:
A1
Abstract:
Disclosed is a stem lock, comprising a lock base (7) and a lock disk (1), and further comprising: a power source (5), a push rod (6), a lock elastic element (11) and a release elastic element (10). The push rod (6) is provided on the lock base (7). The power source (5) is provided on the lock base (7) and is in a transmission connection with one end of the push rod (6), and the power source (5) is used for driving the push rod (6) to move in the direction away from or towards the lock disk (1). The lock elastic element (11) and the release elastic element (10) are provided between a lock tongue (2) and the push rod (6), wherein the lock elastic element (11) is used for driving the lock tongue (2) to move in the direction towards the lock disk (1), and the release elastic element (10) is used for driving the lock tongue (2) to move in the direction away from the lock disk (1). When the lock tongue (2) is locked, the lock tongue (2) and the push rod (6) are two components, and therefore, the power source (5) will continue driving a slide block to move in the direction away from or towards the lock disk (1), such that the lock elastic element (11) or the release elastic element (10) will continue performing elastic deformation to prevent the power source from being locked, affecting the service life of the power source. In addition, further disclosed are a bicycle, electric bicycle and motorcycle using the above-mentioned stem lock.
