On one hand, the contact mode of the spring and the rotary shaft is changed from a point contact mode to a linear contact mode, on the other hand, the stress damage portion of the spring is far away from the rotation space of the spring, the service life of the spring can be greatly prolonged, and accordingly quality of the whole clutch and the intelligent lock is improved.
Description
Technical field
The utility model relates to a kind of clutch being applied on intelligent door lock.
Background technology
The clutch of circulation is varied on the market, with the most general be exactly the rotation by motor, by rotatablely moving and be transformed into rectilinear motion after the train of reduction gears of associated, the transformation of this motion is all finally to realize by the relative motion of axis of rotation and spring.
As the conventional clutch in Fig. 1 ~ 3, it mainly comprises base 1, cover plate 2, motor 3, axis of rotation 7, spring 8, rectilinear motion part 9 and the train of reduction gears being made up of driving gear 4, driven gear 5, reduction gearing 6, motor 3 and axis of rotation 7 are parallel to the both sides that are arranged on base 1 of base 1, be positioned at train of reduction gears rear, driving gear 4 is arranged on the output shaft of motor 3, driven gear 5 is arranged on the front end of axis of rotation 7, reduction gearing 6 is arranged on base 1 front portion by an alignment pin, three gears are positioned at same one end of base 1, reduction gearing 6 has the initiative between gear 4 and driven gear 5, connect driving gear 4 and driven gear 5 and carry out transmission, rectilinear motion part 9 is sleeved on axis of rotation 7, spring 8 is also sleeved on axis of rotation 7, and be positioned at rectilinear motion part 9, after spring 8 two ends pin bendings, radially stretch out, hang on the rectilinear motion part 9 that is positioned at spring 8 two ends, outside rectilinear motion part 9 rear end protuberate basic units 1, axis of rotation 7 is also radially interspersed with a pin, pin two ends pass spring 8, cover plate 2 covers on base 1, form box structure protection internal part and avoid extruding together with base 1.
Motor 3 can forward also can reverse, and is mainly decided by the turn signal receiving.In the time that motor 3 rotates, driving gear 4 on drive motor 3, driving gear 4 drives driven gear 5 and then driven rotary axle 7 by reduction gearing 6 again, and axis of rotation 7 is when rotated, play the also and then rotation of pin on axis of rotation 7, being rotated in the spiral being formed by spring 8 of pin carried out.Because spring 8 two ends pin bending straight lines are drawn and hung on rectilinear motion part 9, limit spring 8 and can not rotate.In the time that pin rotates on spring 8, spring 8 can only do the rectilinear motion that advances, retreats along with spiral along axis of rotation 7, and the action that drives rectilinear motion part 9 to regain or stretch out.
Conventional clutch in use runs into following problem: 1), due to the characteristic of product, axis of rotation diameter is not too large, generally in 3-5mm left and right, and interspersed pin thereon, by punching pin is thrown on axle, processing technology bothers very much.Once as the pin-and-hole on axle occurs gap with the cooperation of pin, pin will drop out, if both interference fit are bigger than normal, be difficult to assembling.It is less than normal that the diameter of axle has also limited the diameter of pin in addition.Above problem causes and is difficult in process of production control and in use very unstable, easily breaks down.
2) spring is to convert straight-line critical component to by rotatablely moving, for restraining spring can be along with axis of rotation rotates, designer is all identical to carry out bending at the two ends of spring pin and tangles rectilinear motion part, to allow the thrust of spring on rectilinear motion part.The wire diameter of spring itself can not be too small or excessive, and it is motionless that the too small meeting of spring wire diameter causes power to push away not, and the excessive meeting of spring wire diameter causes the excessive motor of resistance to drive, therefore the wire diameter of spring is general all in the scope of 0.25-0.4mm.The spring of little wire diameter like this, after the pin bending of two ends, can produce permanent stress injury at bending part, and in use this is a very large potential safety hazard.
Be that a point contacts because pin interacts with spring, and spring bending position is just in time also in contact range.In the time that axis of rotation drives realization to rotatablely move by motor, the contact meeting of point type more easily causes heating, wearing and tearing, and the problem the most easily occurring is to break in spring bending position.In the time breaking in two bending positions on spring, spring will rotate along with axis of rotation, cannot complete the straight-line conversion that rotatablely moves, and whole mechanism cannot normally move again.
3) said mechanism is to install concentratedly in a box body being made up of base and cover plate.Traditional assembling mode comparatively bothers, and axis of rotation will go to install through base, for the position of restriction axis of rotation, also needs to use collar that axis of rotation is stuck in box body.
In addition, cover after cover plate completing the assembling of each parts on base, because box body cannot form a perimeter support, in use, as cover plate pressurized is easy to kill the accessory in box body.At present be mainly to adopt plastics to do box body on the market, whole clutch is that the corresponding position that is directly placed on smart lock is pushed down by product lid above.Now often occur that plastic deformation or product lid distortion build-up of pressure is excessive and kill the problem that the part of box body inside is joined, make the clutch cannot normal operation, cause product quality problem.
