It please refers to shown in attached drawing 1 and Fig. 2 and Figure 10, in the utility model embodiment, provides a kind of lock core structure, Including main component 40, preceding shaft assembly 10, rear axle assemblies 20 and cam member 30.The main component 40 is installed on door when in use, The middle of the main component 40 offers rotation slot 41, which is rotatably connected in the rotation slot 41, and is turning Dynamic process drives the mechanical structure rotation on lockset, to realize unlocking.The preceding limit of shaft assembly 10 is set in the main component In 40 first end, the rear axle assemblies 20 limit is set in the second end of the main component 40, and the first end and second end is preferred For on the same line, and the first end and second end is located at the two sides of the rotation slot 41, and then the cam member 30 In the centre of the preceding shaft assembly 10 and rear axle assemblies 20, and that this may be implemented is convex for the preceding shaft assembly 10 and the cooperation of rear axle assemblies 20 The rotation of gear member 30.

As shown in Fig. 2, the preceding shaft assembly 10 include the first shaft coupling portion 11 and along the first shaft coupling portion 11 end to extension The first connecting shaft 12 and the first engagement unit 13 stretched and the first driving list for driving 13 displacement of the first engagement unit Member 50.For first engagement unit, 13 mobile connection in the first shaft coupling portion 11, first driving unit 50 limit is connected to this In first shaft coupling portion 11 and first connecting shaft 12.

As shown in Fig. 2, the rear axle assemblies 20 include the second shaft coupling portion 21 and along the second shaft coupling portion 21 end to extension The second connecting shaft 22 and the second engagement unit 23 stretched and the second driving list for driving 23 displacement of the second engagement unit Member 60.For second engagement unit, 23 mobile connection in the second shaft coupling portion 21, second driving unit 60 limit is connected to this In second shaft coupling portion 21 and second connecting shaft 22.

As shown in Figure 2, Figure 5 and Figure 6, which is connected between the preceding shaft assembly 10 and rear axle assemblies 20, when after When shaft assembly 20 and the cam member 30 limit connect, the cam member 30 cannot be driven to rotate when preceding shaft assembly 10 rotates at this time, The idle running i.e. on ordinary meaning；And after preceding 10 end unlocking instruction of shaft assembly is assigned, first driving unit 50 driving After first engagement unit 13 forward movement is connect with second engagement unit 23, when external force turns the handle, this first is matched It closes unit 13 and drives the rotation of the second engagement unit 23, and then drive rear axle assemblies 20 to rotate, and then the cam member 30 is driven to rotate, To realize unlocking process.

After current shaft assembly 10 is destroyed, at this point, when second driving unit 60 is controlled by wireless signal, the wireless signal It can be bluetooth, WIFi, fingerprint or APP instruction, and then second driving unit 60 drives 23 direction of the second engagement unit First engagement unit 13 is mobile, so that first engagement unit 13 and the connection of the second engagement unit 23, and then rotated in external force When door handle, which drives second engagement unit 23 rotation, and then realizes the rotation of cam member 30, so as to In unlocking；It can be designed so that the lock core structure forms the structure of dual system in this way, and then work as preceding shaft assembly 10 located outside the door After being destroyed, which still can assist realizing and unlock.

In addition, first driving unit 50 and the second driving unit 60 can also be while being driven, and the cam member The case where 30 connect with the preceding shaft assembly 10 and the limit of rear axle assemblies 20 simultaneously, and idle running is not present in the preceding shaft assembly 10 at this time, I.e. when not having unlocking instruction, preceding shaft assembly 10 cannot be rotated；When the first driving unit 50 and the second driving unit 60 are same When being driven, first engagement unit 13 and the second engagement unit 23 move towards simultaneously, and realize connection, and rotation should at this time When door handle, the preceding shaft assembly 10 and rear axle assemblies 20 rotate realize the cam member 30 rotation simultaneously, and design in this way can guarantee The rotation of cam member 30 is more stable.

The lock core structure designed in this way, by the setting of preceding shaft assembly 10 and rear axle assemblies 20, and the preceding shaft assembly 10 It is inside equipped with the first driving unit 50 and the first engagement unit 13, the second driving unit 60 and second is equipped in the rear axle assemblies 20 and is matched Close unit 23；First driving unit 50 and the second driving unit 60 can simultaneously or separately drive corresponding first to match simultaneously It closes unit 13 and the second engagement unit 23 realizes the rotation of cam member 30 to realize the process of unlocking；And then current shaft assembly 10 or After certain side of rear axle assemblies 20 is destroyed, the function of unlocking still may be implemented.And preceding shaft assembly 10 and rear axle assemblies 20 are equal A single piece can be independently formed, so that the cooperation in lock core is more stable.
