现有的智能门锁，电子开锁过程稳定性差，如遇电机突然停止转动，主锁舌没有完全收回，导致无法开门。鉴于此，本发明提供了一种锁体结构，该锁体结构在电机突然停止转动时，依旧可以使用钥匙开锁。图1为本发明提供的锁体结构的一实施例的结构示意图，图2为图1所示的锁体结构中主锁舌解锁部21、电驱动部22以及操作部23的装配示意图，图3为图1所示的锁体机构中电驱动部的结构示意图。参见图1、图2和图3，锁体结构100包括锁壳1及设于锁壳1内的解锁结构2，解锁结构2包括主锁舌解锁部21、电驱动部22和操作部23；主锁舌解锁部21相对锁壳1活动设置，以具有沿第一方向的第一解锁行程；电驱动部22形成有第一抵接部221和第二抵接部222，第一抵接部221与第二抵接部222依次沿第一方向分设在主锁舌解锁部21的相对两侧，第一抵接部221与主锁舌解锁部21抵接，以驱动主锁舌解锁部21进行第一解锁行程；操作部23与主锁舌解锁部21固定连接，操作部23用于在电驱动部22失效时，带动主锁舌解锁部21沿第一方向靠近第二抵接部222活动，以驱动主锁舌解锁部21进行第一解锁行程。The existing smart door locks have poor stability in the electronic unlocking process. If the motor suddenly stops rotating, the main deadbolt is not fully retracted, resulting in the inability to open the door. In view of this, the present invention provides a lock body structure, which can still be unlocked with a key when the motor suddenly stops rotating. 1 is a schematic structural diagram of an embodiment of a lock body structure provided by the present invention, and FIG. 2 is an assembly schematic diagram of the main latch unlocking part 21 , the electric driving part 22 and the operating part 23 in the lock body structure shown in FIG. 1 . 3 is a schematic structural diagram of the electric drive part in the lock body mechanism shown in FIG. 1 . 1, 2 and 3, the lock body structure 100 includes a lock housing 1 and an unlocking structure 2 disposed in the lock housing 1, and the unlocking structure 2 includes a main lock tongue unlocking part 21, an electric driving part 22 and an operating part 23; The main bolt unlocking portion 21 is movably arranged relative to the lock case 1 to have a first unlocking stroke along the first direction; the electric driving portion 22 is formed with a first abutting portion 221 and a second abutting portion 222 , the first abutting portion 221 and the second abutting portion 222 are respectively disposed on opposite sides of the main bolt unlocking portion 21 along the first direction in turn. The first abutting portion 221 abuts against the main bolt unlocking portion 21 to drive the main bolt unlocking portion 21 The first unlocking stroke is performed; the operation part 23 is fixedly connected with the main lock tongue unlocking part 21 , and the operation part 23 is used to drive the main lock tongue unlocking part 21 to approach the second abutting part 222 along the first direction when the electric drive part 22 fails. move to drive the main lock tongue unlocking part 21 to perform the first unlocking stroke.
本发明提供的锁体结构100包括电驱动部22和操作部23，在开锁过程中，电机组件6驱动电驱动部22活动，以使电驱动部22的第一抵接部221抵推主锁舌解锁部21沿第一方向活动，主锁舌收回；当电机故障或电路板故障导致电驱动部22失效后，使用钥匙或者应急旋钮驱动操作部23活动，操作部23带动主锁舌解锁部21沿第一方向继续活动，而将主锁舌完全收回。本发明提供的锁体结构100，能够在电子开锁过程突然中断后，使用机械开锁方式继续驱动主锁舌收回，进而实现开门，避免因电子锁开锁过程中突遇故障导致用户无法开门的情况出现，提高用户体验。The lock body structure 100 provided by the present invention includes an electric driving part 22 and an operating part 23. During the unlocking process, the motor assembly 6 drives the electric driving part 22 to move, so that the first abutting part 221 of the electric driving part 22 pushes the main lock The tongue unlocking part 21 moves in the first direction, and the main lock tongue is retracted; when the electric drive part 22 fails due to the failure of the motor or the circuit board, the key or emergency knob is used to drive the operation part 23 to move, and the operation part 23 drives the main lock tongue unlocking part 21 continues to move in the first direction and fully retracts the main latch. The lock body structure 100 provided by the present invention can use the mechanical unlocking method to continue to drive the main deadbolt to retract after the electronic unlocking process is suddenly interrupted, thereby realizing the door opening, avoiding the situation that the user cannot open the door due to a sudden failure during the electronic lock unlocking process. , to improve the user experience.
进一步地，主锁舌解锁部21具有沿与第一方向相反的方向的第一上锁行程。在上锁过程中，电驱动部22的第二抵接部222抵推主锁舌解锁部21沿与第一方向相反的方向活动，主锁舌伸出。Further, the main bolt unlocking portion 21 has a first locking stroke in a direction opposite to the first direction. During the locking process, the second abutting portion 222 of the electric driving portion 22 pushes the main lock tongue unlocking portion 21 to move in a direction opposite to the first direction, and the main lock tongue protrudes.
考虑到主锁舌解锁部21位于第一抵接部221和第二抵接部222之间，当电驱动部22驱动主锁舌解锁部21沿第一方向活动时，如遇故障突然中断，那么第二抵接部222阻碍主锁舌解锁部21沿第一方向继续活动。因此，本发明实施例中，主锁舌解锁部21沿第一方向的活动行程为L 1，第一抵接部221和第二抵接部222在第一方向的距离为L 2；其中，L 2≥L 1。此处的设计，当第一抵接部221驱动主锁舌解锁部21沿第一方向活动时，主锁舌解锁部21和第二抵接部222之间形成一让位行程，用以当电驱动部22失效后，操作部23带动主锁舌解锁部21脱离第一抵接部221，并在该让位行程内继续沿第一方向活动，至完成第一解锁行程。如此设计，在电驱动部22失效后，使用较小的力就能使主锁舌收回，用户体验好。 Considering that the main bolt unlocking portion 21 is located between the first abutting portion 221 and the second abutting portion 222, when the electric driving portion 22 drives the main bolt unlocking portion 21 to move in the first direction, in case of a sudden interruption in the event of a fault, Then, the second abutting portion 222 prevents the main bolt unlocking portion 21 from continuing to move in the first direction. Therefore, in the embodiment of the present invention, the movable stroke of the unlocking portion 21 of the main bolt in the first direction is L 1 , and the distance between the first abutting portion 221 and the second abutting portion 222 in the first direction is L 2 ; wherein, L 2 ≥ L 1 . In the design here, when the first abutting portion 221 drives the main lock bolt unlocking portion 21 to move in the first direction, a receding stroke is formed between the main lock bolt unlocking portion 21 and the second abutting portion 222 for when After the electric drive part 22 fails, the operation part 23 drives the main lock tongue unlocking part 21 to disengage from the first abutting part 221 , and continues to move in the first direction within the receding stroke until the first unlocking stroke is completed. With this design, after the electric drive part 22 fails, the main latch can be retracted with a small force, and the user experience is good.
需要说明的是，此处假设主锁舌解锁部21在第一方向上的长度为无限小，因此L 2和L 1满足L 2≥L 1。考虑到实际产品中主锁舌解锁部21在第一方向上的长度不为零，因此，设置主锁舌解锁部21在第一方向上的长度为L 3，那么L 2≥L 1+L 3。也即让位行程沿第一方向的距离至少等于主锁舌解锁部21沿第一方向的活动行程，以在电驱动部22刚要活动就故障时，操作部23能带动主锁舌解锁部21进行第一解锁行程。 It should be noted that, it is assumed here that the length of the main bolt unlocking portion 21 in the first direction is infinitely small, so L 2 and L 1 satisfy L 2 ≧L 1 . Considering that the length of the main bolt unlocking portion 21 in the first direction is not zero in the actual product, therefore, the length of the main bolt unlocking portion 21 in the first direction is set as L 3 , then L 2 ≥L 1 +L 3 . That is, the distance of the relinquishment stroke along the first direction is at least equal to the movement stroke of the main latch unlocking portion 21 along the first direction, so that when the electric drive portion 22 fails just before moving, the operating portion 23 can drive the main latch unlocking portion. 21 Perform the first unlocking stroke.
优选地，L 2和L 1满足：L 2=2L 1。如此设置，能使开锁过程和解锁过程具有相同的动作。例如，设置开锁过程中，第一抵接部221先沿第一方向进行长度为L 1的空行程，然后第一抵接部221抵推主锁舌进行长度为L 1的第一解锁行程，最后第一抵接部221沿与第一方向相反的方向进行长度为L 1的空行程；同样地，设置上锁过程中，第二抵接部222先沿与第一方向相反的方向进行长度为L 1的空行程，此时第二抵接部222正好与主锁舌解锁部21抵接，第二抵接部222继续沿与第一方向相反的方向抵推主锁舌进行长度为L 1的第一上锁行程，最后第二抵接部222沿第一方向进行长度为L 1的孔行程。设置L 2=2L 1可简化电驱动部22的逻辑运算，降低故障率。 Preferably, L 2 and L 1 satisfy: L 2 =2L 1 . With this arrangement, the unlocking process and the unlocking process can have the same action. For example, during the unlocking process, the first abutting portion 221 first performs an idle stroke of length L1 along the first direction, and then the first abutting portion 221 pushes the main latch to perform a first unlocking stroke of length L1, Finally, the first abutting portion 221 performs an idle stroke with a length of L 1 in the direction opposite to the first direction; similarly, during the setting and locking process, the second abutting portion 222 first performs a length in the direction opposite to the first direction. It is an idle stroke of L1, at this time, the second abutting portion 222 just abuts with the main lock tongue unlocking portion 21, and the second abutting portion 222 continues to push the main lock tongue in the opposite direction to the first direction for a length of L. The first locking stroke of 1 , and finally the second abutting portion 222 performs a hole stroke of length L 1 along the first direction. Setting L 2 =2L 1 can simplify the logic operation of the electric drive part 22 and reduce the failure rate.
