Detailed Description

The present invention is further described in detail below with reference to the drawings so that those skilled in the art can implement the invention with reference to the description.

As shown in fig. 1, the clutch device of electronic door lock of the present invention comprises a housing 2 and an end cap 6 assembled in combination, wherein a rotatable dial wheel 4 is arranged in an inner space 21 formed by the housing 2 and the end cap 6. Still including combining set up in elastic component 3 resets on thumb wheel 4, when thumb wheel 4 is driven by external force and rotates, elastic component 3 resets acts on thumb wheel 4 to drive when making external force eliminate thumb wheel 4 carries out the return and rotates, thereby gets back to initial position.

Specifically, in the above-described release mechanism for an electronic door lock, the thumb wheel 4 includes a wheel 43 and a sleeve 44 vertically inserted from the center of the wheel 43. A clamping base 45 is convexly arranged on the surface of the wheel disc 44 in the direction facing the shell 2, and a telescopic clamping column 46 is combined and arranged in the clamping base 45. The elastic restoring element 3 is a spring body formed by winding a plurality of circles, one end head 32 of the spring body is clamped against the clamping base 45, and the other end head 31 of the spring body is clamped against a clamping column 46 protruding from the clamping base 45. Correspondingly, a protruding top column 22 is arranged on one side of the housing 2 facing the thumb wheel 4. Clutch device still including set up in the ball bearing 1 of 2 central trompils 23 departments of casing, the front end 41 of pipe box 44 corresponds wears to establish ball bearing 1, and quilt ball bearing 1 supports and rotates. The end cover also comprises a thrust bearing 5 arranged at the central opening 62 of the end cover 6, and the rear end 42 of the pipe sleeve 44 correspondingly penetrates through the thrust bearing 5 and is supported by the thrust bearing 5 to rotate. Correspondingly, a sunk groove 62 for accommodating the thrust bearing 5 is also arranged at the edge of the central opening 62 of the end cover 6.

In the clutch device of the electronic door lock of the present invention, when the housing 2 is assembled with the end cap 6 (at this time, the front end 41 of the sleeve 44 of the thumb wheel 4 has penetrated through the elastic restoring member 3 and penetrated into the ball bearing 1, the rear end 42 of the sleeve 44 has penetrated into the thrust bearing 5, and one end 32 of the elastic restoring member 3 abuts against the fastening base 45, and the other end 31 abuts against the fastening post 46 protruding from the fastening base 45), as the end cap 6 drives the thumb wheel 4 to move toward the housing 2, the fastening post 46 is abutted against the fastening base 45 by the supporting post 22, in this way, the other end 31 of the spring body then catches against the stud 22 (i.e. is fixed with respect to the casing 2), and one end head 32 still abuts against the clamping base 45 (i.e. is fixed relative to the thumb wheel 4), so that the thumb wheel 4 can rotate in a return manner when the external force is removed.

The utility model discloses in, owing to need not to reset another end 31 of elastic component 3 and the isolated operation again and the card is established to casing 2 on, consequently, can save the step of field assembly greatly, improve production efficiency.

While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
