Background

In recent years, intelligent cabinet locks are gradually emerging, and are widely applied due to the characteristic that the locks can be unlocked through mobile equipment or biological identification without carrying keys.

Except the intelligent door lock, the intelligent lock still includes small-size intelligent lock class products such as cabinet lock, U type lock, padlock, however the actuating mechanism of conventional intelligent lock causes the volume great because of having integrateed electron and mechanical component, and the cost is higher, is not fit for small-size intelligent lock product.

In addition, because the small-sized intelligent lock is small in size, fine in assembly and easy to make mistakes in the production process, a driving mechanism which is compact in structure, low in cost and simple enough in assembly is very needed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the intelligent lock driving mechanism comprises a lock body 1, a bolt 2 is arranged in the lock body 1, the lock tongue 2 slides out of the lock body 1 and also comprises a driving mechanism 3 arranged in the lock body 1, a limiting rod 21 is fixedly arranged at the inner side end of the lock tongue 2, a connecting rod 22 is sleeved on the limiting rod 21 in a sliding manner, the connecting rod 22 is connected with the limiting rod 21 through a spring 23, the driving mechanism 3 comprises a circuit board 4, a motor 5, a reduction gear 6 and a rack 7, the circuit board 4 is electrically connected with the motor 5, the rack 7 is fixed at the end of the connecting rod 22, the length of the rack 7 is less than the width of the inner wall of the lock body 1, the rack 7 is always vertical to the inner wall of the lock body 1, when the rack 7 is at any position between the inner walls of the lock body 1, the reduction gear 6 is always meshed with the rack 7, and the reduction gear 6 is driven by the motor 5 to rotate.

Preferably, the lock body 1 is composed of a bottom shell 11, a middle shell 12 and a top cover 13, wherein the middle shell 12 is fixed on the top of the bottom shell 11 in a buckling mode, the top cover 13 is fixed on the top of the middle shell 13 in a buckling mode, a dry battery 14 is arranged in the middle shell 12, and the dry battery 14 is electrically connected with the circuit board 4.

Further, a battery compartment 15 is provided on the middle case 14 corresponding to the dry battery 14.

Preferably, the circuit board 4 is provided with a bluetooth module.

Preferably, the reduction gear 6 is a reduction gear set composed of a plurality of meshed gears.

The invention provides an intelligent lock driving mechanism which completes unlocking and locking actions mainly through a limit locking state when a reduction gear 6 is meshed with a rack 7.

Under the normal state, the bolt 2 extends out from the bolt opening and is in a locking state. When the unlocking action is executed, the motor 5 rotates, the gear set of the reduction gear 6 is meshed with the rack 7, the rack 7 is driven to linearly advance towards the rear side, the rack 7 drives the bolt 2 to retract towards the bolt opening under the connection of the connecting rod 22 and gradually retract along with the bolt opening, when the rear side end of the rack 7 contacts the inner side wall of the bottom shell 11, the advancing distance is limited, the continuous advancing cannot be realized, at the moment, the rack 7 is still in a meshed state with the reduction gear 6, and the locking cannot be realized due to the continuous advancing, so that the unlocking action is finished. The bolt 2 is in a state of being completely retracted into the bolt opening, so that unlocking is realized.

When the locking action is executed, the motor 5 is controlled to rotate in the opposite direction to drive the rack 7 to linearly advance towards the front side, the rack 7 drives the bolt 2 to extend out of the bolt opening under the connection of the connecting rod 22, when the front side end of the rack 7 contacts the inner side wall of the bottom shell 11, the advancing distance of the rack is limited, the rack cannot continue to advance, the rack 7 is still in a meshed state with the reduction gear 6 at the moment, the lock cannot continue to advance and then is locked, the locking action is executed, the bolt 2 completely extends out of the bolt opening at the moment, the bolt corresponding to the corresponding lock body 1 is inserted and clamped, and the locking is further realized.

In addition, when in a lock closing state, the lock tongue 2 completely extends out of the lock tongue opening, although the rack 7 is locked and cannot move, when the lock tongue 2 is pushed towards the bottom case 11, the lock tongue 2 and the limiting rod 21 still retract into the lock tongue opening under the action of the spring 23, the spring 23 is in a compression state at the moment, and after the pressure is relieved, the spring 23 rebounds reversely to reset, and the lock tongue 2 is rapidly ejected out of the lock tongue opening again. Furthermore, the lock body 1 can be conveniently closed by pushing and pulling corresponding cabinet doors, drawers and other installation objects in a locking operation by matching with the inverted arc state of one side of the bolt 2.

The operation of the motor 5 is controlled by the circuit board 4, and the bluetooth module on the circuit board 4 can be connected with intelligent devices such as a mobile phone of a user, so that convenient and fast intelligent control is realized.
