[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0026] Referring to Figures 1-4 An embodiment provided by the utility model: a safe door clutch drive assembly, comprising a protective shell 1, a box cover 2 is arranged at the upper end of the protective shell 1 in a clamping mode, a push rod 14 is arranged at the bottom of the protective shell 1 in a sliding mode, a key push head 6 is fixedly arranged at the rear end of the push rod 14, a drive rack 7 is arranged at the upper end of the push rod 14 in a sliding mode, a rebound spring 12 is arranged in the drive rack 7 in a clamping mode, one end of the rebound spring 12 is connected to one side of the push rod 14, the other end of the rebound spring 12 is connected to one side in the drive rack 7, a lock head connecting block 5 is fixedly arranged at the side of the push rod 14 away from the drive rack 7, a lock head body 13 is fixedly arranged at one side of the lock head connecting block 5;

[0027] Specifically, in the normal working state, the operation of the drive motor 8 can drive the drive rack 7 to move in a specific direction. The rack and the push rod are connected to each other through the reset spring, so that the push rod also moves in the same direction. Then, the lock head connecting block 5 drives the lock head body 13 to move, thereby completing the locking process. Correspondingly, the reverse rotation of the motor 8 will reset the lock head body 13, realizing unlocking. If the motor 8 fails, the mechanical key can directly operate the push piece inside the safe, so that it is in contact with the key push head 6. Continuing to rotate the key will drive the push rod 14 to move through the key push head 6, thereby completing the unlocking. This design does not need to rely on a complex auxiliary transmission mechanism, realizes a double unlocking mechanism, ensures the safety performance of the safe under different situations, and effectively prevents illegal intrusion and theft.

[0028] Referring to Figure 2 and 3, the bottom of the protective shell 1 is fixedly provided with a motor 8, the output end of the motor 8 is fixedly provided with a worm 9, the bottom of the protective shell 1 is rotatably provided with a first double-layer gear 10 near one side of the motor 8, the bottom of the protective shell 1 is rotatably provided with a second double-layer gear 11 near the first double-layer gear 10, the upper layer of the first double-layer gear 10 is a worm wheel, the upper layer of the first double-layer gear 10 is in meshing connection with the worm 9, the lower layer gear of the first double-layer gear 10 is in meshing connection with the lower layer gear of the second double-layer gear 11, and the upper end of the second double-layer gear 11 is in meshing connection with the rack part of the driving rack 7;

[0029] Specifically, in the safe door clutch drive assembly, the meshing transmission mechanism of the worm 9 and the worm wheel ensures that the unlocking function can only be realized under the driving of the motor 8 due to its inherent self-locking characteristic, thereby significantly improving the safety performance of the safe. Even in the case of motor 8 failure, users can still use the key for emergency unlocking without the help of complex auxiliary transmission mechanism. The design of this double unlocking mechanism ensures the safety of the safe in different situations and effectively prevents illegal intrusion and theft.

[0030] Referring to Figure 1 , the upper end of the box cover 2 is fixedly provided with a nameplate 3, and a plurality of fixing holes 4 are formed through the inside of the box cover 2;

[0031] Specifically, the box cover 2 can be provided with product-related information, and the plurality of fixing holes 4 facilitate the installation of the product to the specified position, improving the stability.

[0032] Working principle: in the normal working state of the safe door clutch drive assembly, the worm 9 is first driven to rotate by the driving motor 8, when the worm 9 rotates, the first double-layer gear 10 meshing with it will rotate, thereby driving the second double-layer gear 11 to rotate, at this time the driving rack 7 will move to one side direction under the driving of the second double-layer gear 11, the driving rack 7 and the toggle lever 14 are connected through the rebound spring 12, at this time the toggle lever 14 will also be driven to move to one side direction, thereby driving the lock body 13 to move through the lock head connecting block 5 to realize locking, similarly, when the motor 8 reverses, it can drive the lock body 13 to reset to realize unlocking.

[0033] Secondly, when the motor 8 fails, the key can drive the inside of the safe to rotate the contact piece to contact the key handle 6, then continue to rotate the key to drive the toggle lever 14 to move through the key handle 6, thereby realizing unlocking.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
