Description

Anti-theft lock for battery of electric bicycle

Technical Field

The utility model relates to a battery theftproof design technical field, concretely relates to electric bicycle battery pickproof lock.

Background

Under the background of the era of vigorous development of new energy, electric vehicles are becoming more and more popular, and batteries, which can be said to be the heart of electric vehicles, can supply necessary current and voltage for the operation of electric motors, so that the market demand for batteries is also rapidly increasing. A good battery can be sold to thousands of yuan, and hundreds of yuan are needed in common, so that high-value things inevitably bring about the problem of theft, and the anti-theft lock of the battery can reduce the occurrence of battery theft to a great extent. In order to prevent batteries from being stolen, some batteries are arranged in a frame, some batteries are arranged under a cushion, but the space is limited, and the batteries have to be arranged outside the frame, so that a battery lock which is simple and reliable to install is very necessary.

The existing vehicle locks suitable for battery external hanging are of different types, but the locking mechanism principles of the vehicle locks are the same, and the vehicle locks are driven by a rotating lock core to rotate an eccentric lug fixedly connected with the lock core for a certain angle, so that the length of the eccentric lug in the moving direction of a lock tongue is lengthened, a spring is further compressed, the lock tongue is retracted into a lock body, and unlocking is realized. The position of the lock tongue and the lock core of the battery lock is relatively fixed, and the battery lock cannot be adapted to the position requirements of various lock tongues and lock cores. The extension length of the spring bolt is an important factor influencing the locking performance of the vehicle lock, the too short extension may not achieve the locking effect with the vehicle frame, the anti-theft capacity is reduced, the extension length of the spring bolt of the battery lock is influenced by the radius of the lock cylinder, the extension length of the spring bolt is large, the size change of an eccentric lug fixedly connected with the lock cylinder in the extension direction of the spring bolt is large, and the radius of the lock cylinder needs to be correspondingly increased to adapt to the size change of the eccentric lug.
