Description

Technical Field

[0001] This utility model relates to the field of steering wheel lock technology, and in particular to an eccentric wheel steering wheel lock used in electric vehicles or motorcycles. Background Technology

[0002] Handlebar locks are generally used on electric vehicles or motorcycles. Their main purpose is to lock the handlebars of the electric vehicle or motorcycle after it is parked to prevent it from being stolen.

[0003] A typical faucet lock includes a lock body and a latch assembly mounted on the lock body. The latch assembly includes a latch and a slider, which is connected to the latch. The slider slides along the X-axis on the lock body, and its movement causes the latch to extend or retract. The lock body has a drive mechanism that moves the slider. The drive mechanism includes a motor, an eccentric gear, and a torsion spring. The motor is fixedly mounted on the lock body, and the eccentric gear rotates on the lock body. The motor drives the eccentric gear to rotate through a transmission assembly. One end of the torsion spring is connected to the eccentric gear, and the other end is connected to the slider. When the eccentric gear rotates forward, it causes the latch to extend out of the lock body, thus locking the lock. When the eccentric gear rotates in the opposite direction, it causes the latch to retract back into the lock body, thus unlocking the lock.

[0004] The aforementioned auger lock has a complex structure, and the torsion spring can only drive the slider to move when the eccentric gear rotates to the deformation point of the torsion spring, which cannot achieve smooth sliding of the slider and the transmission is not stable enough. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art by providing an eccentric wheel type faucet lock, which has a simple structure, is convenient and quick to lock and unlock, and has good stability.

[0006] The technical solution of this utility model is as follows: An eccentric wheel type faucet lock includes a lock housing and a latch assembly. The latch assembly includes a slider and a latch connected to the slider. The slider slides within the lock housing, and the sliding of the slider can cause the latch to extend or retract into the lock housing. A motor is provided within the lock housing to drive the slider to slide. An eccentric wheel is also provided within the lock housing. The eccentric wheel is mounted on the output shaft of the motor and rotates synchronously with the motor. A connecting shaft is provided on the eccentric wheel off-center. A connecting slot is provided on the slider, and the connecting shaft is inserted into the connecting slot to drive the slider to slide and lock the latch when the motor rotates. The latch is extended or retracted, and a return spring is fitted on the latch. The two ends of the return spring are respectively set to abut against the lock housing and the slider. The lock housing is also provided with a detection component for detecting the position of the slider. The detection component includes a first circuit board, a first Hall switch, a second Hall switch and a magnet. The first circuit board is located on one side of the slider. The first Hall switch and the second Hall switch are set on the first circuit board along the sliding direction of the slider. The magnet is set on the slider. When the first Hall switch senses the magnet, the latch is in the extended position. When the second Hall switch senses the magnet, the latch is in the retracted position.

[0007] Using the above technical solution, the motor rotates to drive the eccentric wheel to move.
