Abstract

The utility model relates to an automatic anti-theft lock for expansion brakes, which comprises an expansion brake, a lock assembly and an electric control assembly. The electric control assembly comprises a relay, a silicon-controlled rectifier, a magnetic coil, a voltage stabilizing diode, an electrolytic capacitor and a resistor. The lock assembly comprises a lock tongue portion and a limiting shaft portion, wherein the lock tongue portion comprises a lock tongue, a dish spring sleeved around the extension part of the lock tongue, a magnetic coil and a flange fixed at the front of the lock tongue; and the limiting shaft portion comprises a bar-shaped limiting shaft engaged with the flange, a magnetic coil and a dish spring arranged on the back end surface of the limiting shaft. When the assembly switch is opened, the power source of the electric bike triggers the silicon-controlled rectifier and the coil sleeved around the lock tongue is powered on, so that the dish spring sleeved around the extension part of the lock tongue is contracted, unlocking the lock; and simultaneously the limiting shaft moves axially to the flange, limiting the flange. When the assembly switch is closed, the electrolytic capacitor discharges to trigger the silicon-controlled rectifier and the coil sleeved around the lock tongue is powered on, so that the dish spring sleeved around the rear end of the limiting shaft is contracted, the limiting shaft release the flange, the lock tongue extends forwards and enters into the lock hole, locking the lock. The utility model has the advantages of simple structure, low cost, easy use and excellent anti-theft function.
