Problems solved by technology

[0002] At present, various electric door locks on the market, such as the electric door locks used for motorcycles, have exposed keyholes. Once the lock is unlocked by an abnormal user, that is, the damage of a strong external torque, the riding seam installed in the electric door lock will The piece will be distorted, deformed and broken; as a result, the front lock of the motorcycle will be opened immediately, and the lock will be opened. It is not uncommon for the vehicle to be stolen after it is started. It is also very easy to be opened in a short time, and cannot play an effective role in anti-theft and insurance
