Electronic lock assembly and electronic lock

Technical Field

The present invention relates to the field of locks, and in particular to an electronic lock assembly and an electronic lock.

Background Art

There are a large number of outdoor equipment in the distribution network, such as ring network cabinets, which need to be protected with locks to prevent unauthorized personnel from opening the equipment and causing accidents. At present, the locks used for outdoor distribution equipment are usually mechanical padlocks. Since there are a large number of distribution equipment that need to be locked in the same area, the number of padlocks is very large. If each lock is equipped with a specific key, the inspectors need to carry a large number of keys during outdoor inspections, which is inconvenient to carry and takes a lot of time to find the key corresponding to the padlock. The inspection efficiency is extremely low. In order to improve efficiency, the current common practice is to use the same key for the padlocks of locked outdoor equipment in the same area, which can improve the efficiency of inspections. However, if the numbers on the outdoor equipment fall off, it cannot be ensured that the inspectors open the correct equipment, which can easily cause misoperation.

In order to overcome the above problems, the power supply department has begun to try to set up smart locks that are unlocked with electronic keys on the outdoor equipment of the distribution network. For example, the Chinese patent application with application publication number CN107680212A and application publication date 2018.02.09 discloses a five-protection smart lock and a counterbalance lock verification method for outdoor equipment of the distribution network. The smart lock uses an electronic key to unlock. The management server encodes the smart lock number, electronic key number and other signals and sends them to the electronic key. When unlocking, the smart lock receives the output information of the electronic key to determine whether to unlock. The inspection personnel can open the smart locks of all outdoor equipment of the distribution network in the same area with an authorized electronic key. However, the key of this smart lock still needs to drive the lock core to rotate during the unlocking process, and the unlocking is manually operated, and the unlocking efficiency is low.

In order to achieve precise control, as shown in FIG2 , in this embodiment, a miniature travel switch 183 is further provided in the lock body 11, and the travel switch 183 is connected to the controller for communication. The travel switch 183 is triggered by the lock tongue 14 after the lock head 12 is unlocked and sends a trigger signal to the controller, and the controller controls the running time of the drive motor 161 according to the signal of the travel switch 183. In other embodiments, the rotation angle or rotation time of the drive motor can also be set to meet the position movement requirements of the lock tongue, and in this case, there is no need to set a travel switch.

In this embodiment, in order to prevent the key 2 from being pulled out when the electronic lock 1 is not locked, a card plate 19 is provided on the lock body 11 to hold the key 2 after the key 2 is inserted into the key insertion hole 111 and the electronic lock 1 is unlocked, so as to limit the key 2 from being pulled out before the electronic lock 1 is locked. The corresponding key plug 211 is provided with a card slot 212 for the card plate 19 to be inserted in a direction perpendicular to the insertion direction of the key 2. The card plate 19 is in transmission cooperation with the lock body mounting part, and a lock head matching hole 191 is provided on the card plate 19 for the lock body mounting part 123 to be inserted. The end of the lock body mounting part 123 is set as a cone head, and the conical surface on the cone head forms a guiding slope for guiding the lock body mounting part 123 to be inserted into the lock head matching hole 191, thereby driving the card plate 19 to move. The lock head matching hole 191 opens toward one end of the lock head and is an expanded opening adapted to the cone head to guide the insertion of the cone head. A holding spring 201 is provided between the clamping plate 19 and the lock body 11. The holding spring 201 is used to apply elastic force to the clamping member so that the clamping plate 19 maintains the clamping effect on the key 2. One end of the holding spring 201 presses against the lock body 11, and the other end presses against the clamping plate 19. After the key 2 is inserted into the key insertion hole 111 to complete the unlocking of the electronic lock 1, when the lock head 12 is in the unlocking state, the lock body mounting part 123 is separated from the clamping plate 19, and the clamping plate 19 clamps the key 2 under the action of the holding spring 201. After the electronic lock 1 is locked again, the lock head 12 is in the locked state. During the locking process of the lock head 12, the cone head of the lock body mounting part 123 cooperates with the lock head matching hole 191 on the clamping plate 19 to move the clamping plate 19, and the clamping plate 19 is pulled out of the clamping slot 212 of the key plug 211, so that the clamping plate 19 is separated from the key 2, and the key 2 can be pulled out from the insertion hole 111. The card plate in this embodiment forms a holding piece for holding the key. In other embodiments, the holding piece can also be a card block that cooperates with the protrusion on the key plug or a card pin that cooperates with the card slot on the key plug. The holding piece can also be swingably configured on the lock body. One end of the holding piece is a holding end that cooperates with the key, and the other end is a lock head mating end that cooperates with the lock body mounting part. After the lock head is locked, the lock body mounting part presses against the holding piece, so that the holding end of the holding piece leaves the key. After the lock head is unlocked, the lock body mounting part is separated from the holding piece. A torsion spring is arranged at the swing axis of the holding piece. Under the action of the torsion spring, the holding end enters the card slot on the key plug to realize the holding of the key and prevent the key from falling out.

In this embodiment, the axis of the driving motor 161 is parallel to the moving direction of the lock tongue 14 , so that the structure inside the lock body 11 is more compact, and the controller is arranged between the driving motor 161 and the insertion hole 111 .

In this embodiment, the cross section of the key plug 211 is dumbbell-shaped, and seven contacts are provided on the key-end coupling contact block 22. In other embodiments, the number of contacts on the key-end coupling contact block may be other than seven, such as two, three, or any other number, at least one of which is a key data contact connected to the lock body data contact signal, and at least one is a key conductive contact conductively connected to the lock body conductive contact.

As shown in FIG6 , during the unlocking operation, the key 2 is held and the wake-up button 23 on the key 2 is pressed, and the communication module establishes communication with the portable terminal. The communication form is Bluetooth communication. The lock code or work order number is input on the portable terminal to automatically obtain the unlocking password from the system. After the password is received, the indicator light 24 is green, and if it is not completed, the red light is on. The key plug 211 of the key 2 is inserted into the socket 111 of the lock body 11 and inserted to the bottom. At this time, all the contacts on the key end coupling contact block 22 are in contact with all the contacts on the lock body end coupling contact sheet 182. The contacts on the key end coupling contact block 22 are floating contacts. Before the key 2 is inserted to the bottom, all the contacts are in contact. After the key 2 is inserted to the bottom, all the contacts on the key 2 can give way a little. The contacts on the key 2 are in close contact under the action of the spring force. Then press the unlock button on the key 2, the controller connects the memory 181 and the travel switch 183, reads the unlocking password information stored in the memory 181, and compares it with the unlocking password obtained by the key 2 through communication. If the password is correct, the controller connects the power supply circuit of the drive motor 161 to power the drive motor 161, and the drive motor 161 rotates, driving the cam 162 installed on the end of the output shaft of the drive motor 161 to move the lock tongue 14. When the lock tongue 14 moves to the extreme position, the lock tongue 14 pushes the contact of the travel switch 183 to trigger the travel switch 183, and the travel switch 183 sends a signal to the controller, indicating that the lock has been opened. At this time, the lock head 12 bounces up under the action of the unlocking spring, and the electronic lock 1 is opened. The controller controls the drive motor 161 to continue to rotate, and the lock tongue 14 returns under the action of the lock spring 17. The contact of the travel switch 183 also returns under the action of the lock spring 17, and the drive motor 161 continues to rotate for a specified time and stops, completing the unlocking process. After completion, keep the power on state for several seconds to restore the standby dormant state.
