One with another surface of central part 20 it is perforative perforation 22；The central part 20 is equipped with a first bearing for having hoodle screw 241
24, hoodle screw 241 is butted on the lateral surface of central part 20 to provide resistance.The output gear piece 10, central part 20 and output
30 are coupled for stacking, and output gear piece 10 surface corresponding with central part 20 is equipped with multiple clutch protrusions 11, defeated
The surface corresponding with central part 20 of part 30 is equipped with multiple clutch recess portions 31 out；The ball 40 is arranged in groove 21, turns
Dynamic clutch protrusion 11 drives ball 40 and clutch recess portion 31 to form clutch connection.
In the present embodiment, the left and right sides of the clutch protrusion 11 slope inwardly to be formed with the first inclined-plane 111
Double wedge structure, 21 left and right sides of groove are equipped with the second inclined-plane 211 to fit with the first inclined-plane 111, when output gear piece
When 10 rotation, ball 40 can move upwards through perforation 22 using the first inclined-plane 111 and the second inclined-plane 211, and to be stuck in clutch recessed
Connection is formed in portion 31.Specifically, the ball 10 is two be arranged in groove 21, when output gear piece 10 and central part
After 20 stackings are coupled, 11 top surface of clutch protrusion is less than the diameter of ball 40 at a distance from 21 bottom surface of groove, and ball 40 separates
In the left and right sides of clutch protrusion 11；It would not make 40, two balls when clutch protrusion 11 is moved in groove 21
In phase the same side of clutch protrusion 11.
The depth of the clutch recess portion 31 be less than ball 40 diameter, say in more detail, the clutch recess portion 31 it is straight
Diameter is configured to accommodate the size of ball 40, and depth is then the one third of 40 diameter of ball between 2/3rds；In this way
In the state of " conjunction ", 40 a part of ball is stuck in perforation 22, and another part is stuck in clutch recess portion 31, is driven with this defeated
Part 30 rotates out.
The first limit hole 13 is equipped in the middle part of the output gear piece 10,20 bottom surface of central part has extended downwardly the first limit
Position portion 23, first limiting section 23 are assemblied in the first limit hole 13, and the first bearing 241 is assemblied in the first limiting section 23
End；Specifically, the hoodle screw 241 can be butted on the outer surface of the first limiting section 23 to provide resistance to central part 20；
Certain resistance can be provided to central part 20 when exporting gear piece 10 and rotating, central part 20 will not be because of output gear piece 10
Rotation generate inertia rotation, be just able to achieve output gear piece 10 in this way and first drive cunning on ball 40 in the groove 21 of central part 20
Resynchronisation rotation after being connect with output 30.
The central part 20 is equipped with the second limit hole 25, and 30 bottom surface of output is equipped with the second limiting section 32, this
Two limiting sections 32 are assemblied in the second limit hole 25.30 top surface of output, which upwardly extends, is equipped with second bearing 33, this is defeated
Part 30 is equipped with one for being pivotally connected the pivoted hole 34 of rocker arm out, and the one end for the rocker arm being connected on door-plate is articulated in the pivoted hole
In 34, drives rocker arm to swing using the clutch structure and realize automatic door opening or shutdown work.
It further include having driving motor 50, the first tooth group 60, the second tooth group 70 and protective shell 80, the driving motor 50
Main shaft be connected with worm screw 51, worm screw 51 engages 60 with the first tooth group, and the first tooth group 60 is engaged with the second tooth group 70, the second tooth group
70 engage with output gear piece 10.The protective shell 80 is made of bottom case 81 and upper cover 82；The upper cover 82 is assemblied in shape on bottom case 81
At an installation cavity 801, each components are accommodated in the installation cavity 801.It is assembled between the bottom case 81 and upper cover 82 with buckle-type
Or fastened by screw assembly；The side of the bottom case 81 has a motor installation position 811 for being equipped with avoid holes 812, the drive
The main shaft of dynamic motor 50 passes through the avoid holes 812 and extends in installation cavity 801.
The working principle that the utility model is described in detail is as follows: there are three types of state, the first shapes altogether for the ball clutch structure
Under state, (referring to fig. 4) described ball 40 is moved not over clutch protrusion 11 to be stuck between perforation 22 and clutch recess portion 31；
At this time there is no being connected together by ball 40 between output 30 and central part 20, under such state, even if driving
The driving motor 50 that output gear piece 10 rotates is under off-position, and only output and the rocker arm connecting with door-plate is connected to
, and the other components and motor of output and clutch are disjunct, so user also can using the power of very little
Door is easily opened,
Under second of state, (referring to Fig. 5) driving motor 50 drives output gear piece 10 to rotate, during rotation, clutch
Protrusion 11 drives the ball 40 of wherein side to move up and is sticked between perforation 22 and clutch recess portion 31 to drive central part 20
It is rotated with output 30 toward the same direction, and the rocker arm for being articulated in output 30 at this time then can be because the rotation of clutch structure be to reality
It now opens the door or closes the door.
Under the third state, (referring to Fig. 5) driving motor 50 drives output gear piece 10 to rotate, during rotation, clutch
Protrusion 11 drives the ball 40 of other side to move up and is sticked between perforation 22 and clutch recess portion 31 to drive central part 20
It is rotated with output 30 toward the same direction, and the rocker arm for being articulated in output 30 at this time then can be because the rotation of clutch structure be to reality
It now opens the door or closes the door.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change
Change and modify, is still within the scope of the technical solutions of the present invention.
