Referring to fig. 1-4, in this embodiment: the intelligent lock device with the clutch function built in the motor comprises a rear lock shell 1, wherein a motor 12 is arranged inside the rear lock shell 1, a gear set is arranged inside the rear lock shell 1 and comprises a large gear 9, a clutch 3 is arranged inside the large gear 9, the outer side of the clutch 3 is rotatably connected with an annular limiting part 7, a clutch limiting rotating groove 10 is formed between the clutch 3 and the annular limiting part 7, a linkage lug 14 is arranged on the inner side of the annular limiting part 7, and a limiting lug 5 is arranged on the outer side of the clutch 3; the spacing lug 5 and the linkage lug 14 are arranged to form a clutch spacing rotating groove 10 between the clutch 3 and the annular spacing part 7, the range of forward or reverse twisting of the door handle 2 is less than 90 degrees, when the rotating shaft 13 drives the clutch 3 to rotate, the rotating range of the clutch 3 is limited in the clutch spacing rotating groove 10, and the limit lug 5 on the clutch 3 can not contact the linkage lug 14, so the effect of driving the large gear 9 to rotate can not be achieved, thereby realizing the effect that the unlocking by using the door handle 2 is not influenced by the gear set, in addition, the gear set is driven to rotate by arranging the motor 12, the rotating angle is more than 90 degrees, the large gear 9 drives the clutch 3 to rotate by utilizing the linkage lug 14 and the limit lug 5, therefore, the effect of electric unlocking of the motor 12 linkage square tube 6 is achieved, the internal structures of the device are not interfered with each other, and the manual and electric unlocking effect is normally carried out.

One side of the rear lock shell 1 is rotatably connected with a door handle 2, one side of the door handle 2 is rotatably connected with a rotating shaft 13, and the rotating shaft 13 penetrates through the rear lock shell 1 and is connected with one end of the clutch 3; through setting up axis of rotation 13, realize that 2 linkage separation and reunion 3 of door handle rotate the effect.

A gear box shell 11 is arranged in the rear lock shell 1, and a gear set is arranged in the gear box shell 11; by arranging the gear box shell 11, the protection effect on the gear set is realized.

The inner side of the large gear 9 is rotatably connected with a bearing 8, the annular limiting part 7 is rotatably connected to the inner side of the bearing 8, and the size and shape of the limiting lug 5 are matched with those of the linkage lug 14; the effect that the large gear 9 drives the annular limiting part 7 to rotate synchronously is achieved by arranging the bearing 8, and the effect that the linkage clutch 3 rotates is achieved when the linkage lug 14 is in contact with the limiting lug 5.

A square through groove 4 is formed in one end of the clutch 3, and a square tube 6 is arranged in the square through groove 4; through setting up square through groove 4, realize that square through 6 installs inside separation and reunion 3.

The output end of the motor 12 is connected with the gear set, and the motor 12 is arranged below the gear box shell 11; the output end of the motor 12 is connected with the gear set, so that the motor 12 is linked with the square tube 6 to rotate, and the effect of intelligent locking and unlocking is achieved.

The utility model discloses a theory of operation and use flow: when the intelligent unlocking operation of the door is carried out indoors through the device, the motor 12 in the rear lock shell 1 can be utilized, an unlocking signal is received through the motor 12, the motor 12 is started, and drives the gear set in the gear box shell 11 to rotate, at the moment, the annular limiting part 7 on the inner side of the gear wheel 9 realizes the rotating effect of the gear wheel 9 along with the gear wheel 9 through the bearing 8, when the linkage lug 14 on the annular limiting part 7 rotates to be attached to the limiting lug 5, the annular limiting part 7 drives the clutch 3 to rotate synchronously, thereby realizing the rotating unlocking effect of the linkage square tube 6 of the gear wheel 9, when the unlocking is required through the door handle 2, the rotating shaft 13 drives the clutch 3 to rotate, because the rotating angle interval of the door 2 is less than 90 degrees, the rotating range of the handle 3 is limited in the clutch limiting rotating groove 10, and the limiting lug 5 cannot be attached to the linkage lug 14, thereby separation and reunion 3 can't drive gear wheel 9 and rotate, from this, when realizing using 2 rotation square tube 6 unblocks of door handle, does not receive the effect of gear wheel 9 influence, has avoided its inside part mutual interference problem to realize this device manual, electronic multimode unblock function.

The above only is the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all under the concept of the present invention, the equivalent structure transformation made by the contents of the specification and the drawings is utilized, or the direct/indirect application is included in other related technical fields in the patent protection scope of the present invention.
