Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic lock, in particular to a linkage module applied to an electronic lock. BACKGROUND

[0002] The existing electronic lock usually has an indoor control mechanism and an outdoor control mechanism, so that the user inside the door can control the electronic lock to lock or unlock through the indoor control mechanism, and the user outside the door can control the electronic lock to lock or unlock through the outdoor control mechanism. In other words, the existing electronic lock needs to set two groups of the same control device, which is complex in structure and prone to failure.

[0003] On the other hand, when the existing electronic lock is set in a special environment, such as the vault door of a bank, at this time, in order to prevent theft, the user inside or outside the door needs to verify the identity through an access control machine first, and then control the indoor and outdoor control mechanisms to unlock the electronic lock. However, such a setting method has safety concerns when the power is cut off in an emergency such as a fire, and the user inside the door will be locked in the vault and cannot be unlocked. If the control method of automatic unlocking after power failure is adopted, the user outside the door can freely enter the vault after the power is cut off, which loses the anti-theft effect.

Preferably, the central shaft 63 is further sleeved with a shaft sleeve 631. The shaft sleeve 631 is located between the first rotating member 61 and the second rotating member 62, so that the first rotating member 61 and the second rotating member 62 do not interfere with each other when rotating.

[0031] Please refer to Figure 4 , Figure 5 and Figure 6As shown, the linkage module 60 further has a linkage member 64, which has a shaft portion 641 and can rotate about the shaft portion 641, and the shaft portion 641 has a first pushing portion 642 extending radially therefrom corresponding to the first pushing-receiving portion 613, and has a second pushing portion 643 extending radially therefrom corresponding to the second pushing-receiving portion 623.

The other end of the first connecting rod 65 is provided with a first abutting end 653 abutting against the first pushing-receiving portion 613. On the other hand, the body 10 is provided with a second sliding hole 18, and the second connecting rod 66 is provided with a second sliding block 661 arranged in the second sliding hole 18 in a slidable manner, so that the second connecting rod 66 can slide along the second sliding hole 18. The second pushing portion 643 is provided with a second long hole 645, and one end of the second connecting rod 66 is provided with a second protruding column 662 arranged in the second long hole 645 in a slidable manner. The other end of the second connecting rod 66 is provided with a second abutting end 663 abutting against the second pushing-receiving portion 623.

[0032] Please refer to Figure 4 、 Figure 5 and Figure 6As shown, the linkage member 64 is further provided with a driven portion 646 connected with a driving member 67, the driving member 67 can drive the driven portion 646 to drive the linkage member 64 to rotate, so that the linkage member 64 can simultaneously push the first pushing portion 642 and the second pushing portion 643 to drive the first rotating member 61 and the second rotating member 62 to rotate. In the embodiment, the body 10 is provided with a plurality of third sliding holes 19, the driving member 67 is provided with a sliding rod 671 provided with a plurality of third protrusions 672, each of the third protrusions 672 is slidably arranged in each of the third sliding holes 19, so that the sliding rod 671 can slide along each of the third sliding holes 19. Meanwhile, the driven portion 646 is a long hole, one end of the sliding rod 671 is provided with a third protruding column 673 slidably arranged in the driven portion 646, and the other end of the sliding rod 671 is connected with a motor 674. In addition, the sliding rod 671 is provided with a gear row 675, and the motor 674 is provided with a gear 676 engaged with the gear row 675.

[0033] Please refer to Figure 7 and Figure 8 As shown, the linkage member 64 is further provided with a driven portion 646 connected with a driving member 67, the driving member 67 can drive the driven portion 646 to drive the linkage member 64 to rotate, so that the linkage member 64 can simultaneously push the first pushing portion 642 and the second pushing portion 643 to drive the first rotating member 61 and the second rotating member 62 to rotate. In the embodiment, the body 10 is provided with a plurality of third sliding holes 19, the driving member 67 is provided with a sliding rod 671 provided with a plurality of third protrusions 672, each of the third protrusions 672 is slidably arranged in each of the third sliding holes 19, so that the sliding rod 671 can slide along each of the third sliding holes 19. Meanwhile, the driven portion 646 is a long hole, one end of the sliding rod 671 is provided with a third protruding column 673 slidably arranged in the driven portion 646, and the other end of the sliding rod 671 is connected with a motor 674. In addition, the sliding rod 671 is provided with a gear row 675, and the motor 674 is provided with a gear 676 engaged with the gear row 675. Figure 7In the first position shown, the linkage 64 simultaneously drives the first linkage 65 and the second linkage 66 to slide in a push-pull manner, causing the first rotating member 61 and the second rotating member 62 to rotate in opposite directions. At this time, the first pressing part 612 moves away from the first sliding pin 24, causing the first locking part 241 to disengage from the first locking groove 222. Thus, when the user turns the first handle 30, the first handle 30 will drive the first inner rotating member 22 to rotate freely relative to the first outer rotating member 21, and will not be able to further drive the latch 12. On the other hand, the second pressing part 622 will push the second sliding pin 44 to move towards the second inner rotating member 42, causing the second locking part 441 to lock in the second locking groove 422. Thus, when the user turns the second handle 50, the second handle 50 can drive the second inner rotating member 42 to drive the second outer rotating member 41 to rotate synchronously, so that the second drive arm 431 can drive the latch 12 to move.

[0034] Please refer to the following: Figure 9 as well as Figure 10 As shown, when the driving member 67 reverses the driving force, the linkage 64 rotates to a position where Figure 9 In the second position shown, the linkage 64 simultaneously drives the first linkage 65 and the second linkage 66 to slide in a push-pull manner, causing the first rotating member 61 and the second rotating member 62 to rotate in opposite directions. At this time, the first pressing part 612 pushes the first sliding pin 24 to move towards the first inner rotating member 22, causing the first locking part 241 to engage with the first locking groove 222. Simultaneously, the second pressing part 622 moves away from the second sliding pin 44, causing the second locking part 441 to disengage from the second locking groove 422. This allows the first handle 30 to move the locking tongue 12, while the second handle 50 will rotate freely. In this way, the linkage module 60 can simultaneously drive the first clutch module 20 and the second clutch module 40 to engage and disengage through a single drive member 67, thus enabling... The control structure of the electronic lock 100 is greatly simplified. Because the drive member 67 controls the first and second rotating members 61 and 62 to rotate in opposite directions through the linkage member 64, it simultaneously controls the first and second clutch modules 20 and 40, realizing the function of single-direction passage where only the outside is unlocked and the inside is locked, or the outside is locked and the inside is unlocked. In normal circumstances, users outside or inside can unlock the door through the access control machine. In emergency situations, the door can be set to lock from the outside and unlock from the inside, thus achieving both security and anti-theft effects. In addition, when the door setting direction is changed (i.e., the inside and outside are swapped), the present invention only needs to change the driving direction of the drive member 67, without disassembling the electronic lock 100 for adjustment, which makes it more convenient for users to set the electronic lock 100.

[0035] The above embodiments are only the preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Any equivalent replacement or transformation based on the present application, or reasonable mixing of the features and schemes of the embodiments, is within the protection scope of the present application.
