Electric control mechanical lock for moped

Abstract

The invention relates to an electric control mechanical lock for a moped. The lock comprises a lock box, a box cover, an electric device installed in the lock box and a lock opening / closing executingmechanism connected with the electric device. The electric device is connected with the lock opening / closing executing mechanism are connected through a worm and gear pair. The electric device comprises a motor, the worm and gear pair and an output gear. The lock opening / closing executing mechanism comprises a sliding block, and a rack engaged with the output gear is arranged on the sliding block.The sliding block is installed on a guide rod in a sliding mode, the guide rod is installed on the lock box, an executing arm is arranged on the side, opposite to the rack, of the sliding block and provided with a lock rod in a sliding mode, a spring bolt is installed at the end, corresponding to a spring bolt hole, of the lock rod, the other end is provided with a limiting guide plate, the lockrod portion between the executing arm and the inner end face of the spring bolt is sleeved with an upper lock pressing spring, the lock rod portion between the executing arm and the inner end face ofthe limiting guide plate is sleeved with a reset spring, and a limiting baffle is arranged on a sliding groove and located on the same side as the limiting guide plate. The electric control mechanicallock has the advantages of being simple in structure, convenient and fast to assemble and disassemble, flexile in installation position, fast to open and close, high in stability, long in service life, free of clamping and wide in application range.

[0002] At present, with the rapid development of society and the increasing awareness of environmental protection, electric mopeds have become a very important means of transportation in people's daily work and life; however, due to the limitation of volume and weight, electric mopeds or motorcycles are difficult Carry it with you, so people need to store it under the office building or a temporary parking spot in the community, but accidents of loss and theft often occur; so engineers have designed a variety of anti-theft measures for electric mopeds or motorcycles, such as installing Anti-theft locks; this type of anti-theft locks mainly include saddle locks, handlebar locks, etc.; through long-term use, it has been found that most of the traditional anti-theft locks are purely mechanical locks, so there are the following defects: 1. When unlocking, the key must be Insert it into the lock hole, so that once the key is damaged and deformed, it will be difficult to open the lock handle; second, once the key hole is damp, it will often rust, which will affect the effect of unlocking; third, if a single mechanical lock is installed, the anti-theft effect is not good, If multiple mechanical locks are installed, the unlocking process will be cumbersome and the efficiency of unlocking will be reduced

The condition for realizing the above-mentioned electronic lock is that when the straight teeth on the front face of the locking teeth and the transmission gear on the motor shaft of the electric vehicle are facing each other, the meshing between the two can be satisfied, otherwise the locking will not be realized, and there will be a gap This phenomenon, when locked, the remote sensor switch receives the signal, the micro-motor circuit is connected and starts to rotate, the motor shaft drives the worm to rotate synchronously, and then the worm drives the worm wheel, and is driven by the ratchet to the linkage rack, so that the rack Move forward and drive the locking teeth to move forward. The straight teeth on the front end of the locking teeth cannot be engaged with the transmission gear on the motor shaft of the electric vehicle. At this time, the micro-motor has not reached an effective locking stroke, and the motor is still rotating. The appearance of this phenomenon will cause the problem of motor burnout. Once the motor is damaged, the electronic lock will lose its meaning of existence, and it will bring some troubles for later maintenance.
