The present invention generally relates to lock structures and, more particular to, structures of electronic lock.
In general, an electronic lock is driven by a motor. The motor drives a dead bolt performing a retractable movement, and the lock of a latch bolt is controlled by a blocking of the dead bolt so as to achieve switches of a door through the electronic lock.
However, the power of the operation of the motor comes from the battery. Because the power stored in the battery is limited, the frequency of battery replacement can be reduced if the power consumption is decreased. Therefore, if the motor drives mechanism components of light weights (smaller load), the power consumption of the motor will be decreased, and the frequency of battery replacement will be reduced as well.
In view of the above drawbacks, the Inventor proposes the present invention based on his expert knowledge and elaborate researches in order to solve the problems of prior art.
Accordingly, an object of the present invention is to provide structures of electronic lock, in which the motor drives the actuating cam for moving the abutting plate, and the clamping of the locking column is controlled by the tongue pillar through the blocking of the abutting plate; thus, the power consumption of the motor will be reduced, and the frequency of battery replacement will be reduced, too.
In order to achieve the object mentioned above, the present invention provides structures of electronic lock including a pair of lock faceplates with a lock hole separately, a driving assembly, an abutting plate, a latch assembly, and a stopper group. The driving assembly includes a circuit board, a motor electrically connected with the circuit board, and an actuating cam driven by the motor. The abutting plate has a stopper portion and an accommodating opening disposed corresponding to the actuating cam. The actuating cam rotates into the accommodating opening to drive the abutting plate moving back and forth in a straight line. The latch assembly includes a locking column being capable of being inserted in the lock hole, and a buckling slot is provided at an outer periphery of the locking column. The stopper group includes a tongue pillar, a first resilience component elastically pushing the tongue pillar, and a tongue bolt. The tongue pillar is inserted in the buckling slot through the pushing of the first resilience component; wherein, the abutting plate moves back and forth that makes the stop portion to selectively block the tongue bolt; the tongue pillar can be disengaged from the buckling slot through the tongue pillar blocked the tongue bolt and the elastic compression of the first resilience component so that the locking column can be moved out of the lock hole.
Compared to the prior art, the structures of electronic lock of the present invention utilizes the motor to drive the actuating cam for moving the abutting plate, and the clamping of the locking column is controlled by the tongue pillar through the blocking of the abutting plate for performing operations of unlock and lock of the electronic lock. Moreover, since the motor drives the actuation cam of a lighter weight (less loaded), a less power consumption is required. Thus, the power consumption of the motor will be reduced, and the frequency of battery replacement will be reduced, too.
The features of the invention believed to be novel are set forth with particularity in the appended claims. The invention itself, however, may be best understood by reference to the following detailed description of the invention, which describes a number of exemplary embodiments of the invention, taken in conjunction with the accompanying drawings, in which:
In cooperation with attached drawings, the technical contents and detailed description of the invention are described thereinafter according to a number of preferable embodiments, being not used to limit its executing scope. Any equivalent variation and modification made according to appended claims is all covered by the claims claimed by the present invention.

In one embodiment of the present invention, the driving assembly 20 includes a circuit board 21, a motor 22 electrically connected with the circuit board 21, and an actuating cam 23 driven by the motor 22. In addition, the driver assembly 20 further includes a battery 24 electrically connected with the circuit board 21. The battery has a power socket 241, and the power socket 241 is provided for plugging an external power plug to charge the battery 24.
Moreover, the structures of electronic lock 1 further includes a pair of doorplates 100. The pair of lock faceplates 10 are extended perpendicularly from the doorplates 100 correspondingly, and each of the lock faceplates 10 has a lock hole 11 on a side oppositely.
Preferably, the structures of electronic lock 1 further includes a lock shell 60. The pair of doorplates 100 are provided with an enclosing plate 101 corresponding to a configuration of the lock shell 60 separately; the lock shell 60 is inserted in the enclosing plates and covers the pair of the lock faceplates 10, the driver assembly 20, the abutting plate 30, the latch assembly 40, and the stopper group 50.
More in detail, the driver assembly 20, the abutting plate 30, the latch assembly 40, and the stopper group 50 can be assembled in the lock shell 60; thus, the lock shell 60 together with control mechanisms provided in the lock shell 60 can be separated integrally from the pair of doorplates 100 when the latch assembly 40 is detached from the pair of lock faceplates 10.

Moreover, the abutting plate 30 has a stopper portion 31 and an accommodating opening 32 disposed corresponding to the actuating cam 23; an inner wall of the accommodating opening 32 is disposed corresponding to an outline of the actuating cam 23. Therefore, the actuating cam 23 rotates into the accommodating opening 32 to drive the abutting plate 30 moving back and forth in a straight line. In addition, the stopper portion 31 is located at a side of the accommodating opening 32, and the abutting plate 30 has a hollow portion 33 at a side of the stopper portion 31.
Furthermore, the latch assembly includes a locking column 41 being capable of inserting in the lock hole 11 of the lock faceplate 10, and a buckling slot 42 is provided at an outer periphery of the locking column 41. Besides, the stopper group 50 includes a tongue pillar 51, a first resilience component 52 elastically pushing the tongue pillar 51, and a tongue bolt 53 being capable of elastically stretching out the tongue pillar 51, wherein the tongue pillar 51 is inserted in the buckling slot 42 through the pushing of the first resilience component 52. Preferably, the first resilience component 52 is a compression spring.
Preferably, the structures of electronic lock 1 further includes a supporting seat 70. The supporting seat 70 has formed with an accommodating hole 71 and a notch 72 located at a side of the accommodating opening 71. Moreover, the accommodating opening 71 is received with the first resilience component 52 and the tongue pillar 51, and the abutting plate 30 is disposed in the notch 72.
More in detail, the supporting seat 70 has a supporting plate 73 formed at a side of the notch 72. The actuating cam 23 is installed in the supporting seat 70 and located at an inner side of the supporting plate 73. The motor 22 is located at an outer side of the supporting plate 73 corresponding to the actuating cam 23.
It is worth noting that, please refer to
The latch assembly 40 further includes a second resilience component 43 elastically pushing the locking column 41; preferably, the second resilience component 43 is a compression spring. As shown in
Therefore, the abutting plate 30 moves back and forth that makes the stopper portion 31 to selectively block the tongue bolt 53. The tongue pillar 51 can be disengaged from the buckling slot 42 through a blocking of the tongue bolt 53 and an elastic compression of the first resilience component 52 so that the locking column 41 can be moved out of the lock hole 11 of the pair of the lock faceplates 10 for performing an operation of unlock. That is, the abutting plate 30 is moved back and forth so that the tongue bolt 53 is selectively located at the stopper portion 31 or the hollow portion 33. The tongue bolt 53 is located at the hollow portion 33 so that the tongue pillar 51 is inserted in the buckling slot 42 through the pushing of the first resilience component 52. At this moment, the locking column 41 cannot be moved out of the lock hole 11 of the pair of door faceplates 10 in a locking status.
