Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment: an intelligent door lock motor driving device comprises a face box 1, a bottom box 2, a motor 3, a main gear 4, a driven gear 5, a driving shaft 6, a spiral spring 7, a reciprocating block 8, a clamping position 9, a partition plate 10 and a track 11, wherein the face box 1 is fixedly connected to the bottom box 2, the motor 3 is arranged on one side of the inside of the bottom box 2, the main gear 4 is coaxially arranged on a power output shaft of the motor 3, the partition plate 10 is arranged on the other side of the inside of the bottom box 2, the partition plate 10 is L-shaped, the inside of the bottom box 2 is divided into two areas, and one half of the two areas is used for accommodating the motor 3; a reciprocating block 8 is matched in the partition plate 10, the reciprocating block 8 is matched in the other half of the bottom box 2 divided by the partition plate 10, and one end of the reciprocating block 8 extends out of the bottom box 2; one end of a driving shaft 6 sequentially penetrates through a partition plate 10 and one end of a reciprocating block 8 to be connected with the bottom box 2, the other end of the driving shaft 6 is coaxially connected with a driven gear 5 on the outer side of the partition plate 10, and the driven gear 5 is meshed with the main gear 4; the spring slot position formed by the reciprocating block 8 and the partition plate 10 is internally provided with a spiral spring 7, the spiral spring 7 is sleeved on the outer wall of the driving shaft 6, the middle part of the driving shaft 6 is provided with a clamping position 9, the clamping position 9 is matched with the spiral spring 7, and the starting point and the terminal point of the spiral spring 7 extend out of the outer side of the track 11 at the bottom of the bottom box 2.

The principle of the utility model is that:

when the motor 3 receives an instruction to drive the main gear 4 to drive the driven gear 5 to rotate, so as to drive the driving shaft 6 to rotate, the part of the spiral spring 7 extending to the outer side of the bottom box 2 only moves up and down on the track 11 and cannot rotate along with the track, when the driving shaft 6 rotates, the clamping position 9 on the driving shaft 6 pushes the spiral spring 7 to move forward or backward, because the spiral spring 7 is arranged in a spring groove formed between the reciprocating block 8 and the partition plate 10, the spiral spring 7 pushes the reciprocating block 8 to move forward or backward when moving forward or backward, and when the motor 3 receives an instruction to open the door, the reciprocating block 8 is pushed forward to realize unlocking; when the motor 3 receives an instruction to lock the door, the reciprocating block 8 retreats to lock the door.

To sum up, the utility model discloses an elastic element and mechanical element cooperate, have solved worm gear straight line back and forth movement and have caused the card to die, lead to the problem that the intelligence lock broke down, have reduced the fault rate, prolong the life of intelligence lock. When the spiral spring 7 moves forward or moves backward, the reciprocating block 8 is pushed to move forward or move backward and is matched with the reciprocating cylinder 9 and the spring 14, a spiral rod is not needed to directly push, the power of the motor 3 is reduced, and therefore electric energy is saved and batteries do not need to be frequently replaced.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
