31 rotations of the 1st gear part are bearing on the metal shaft 24 freely, the two supports of this metal shaft 24 is on housing 8, and the 1st gear part 31 is by constituting with the major diameter driven gear 31a of worm screw 34 engagement with the minor diameter feed gear wheel 31b of the driven gear 32a engagement of the 2nd gear part 32.This driven gear 31a and feed gear wheel 31b form one.
The 2nd gear part 32 has such structure: just in case occur in the course of action of liftout component 5 liftout component 5 pushing or the power of pulling out from housing 8 to housing 8 in by force, it can be with this power release.That is, the 2nd gear part 32 by: and the driven gear 32a of the feed gear wheel 31b of the 1st gear part 31 engagement, with the feed gear wheel 32b of spur gear 35 engagements of the driven gear that becomes the 3rd gear 33, be clipped in SUS system flat board 32c between driven gear 32a and the feed gear wheel 32b, make driven gear 32a and feed gear wheel 32b clip dull and stereotyped 32c to form one and prevent the clutch spring 32d formation that overload is used.
The 2nd gear part 32 of said structure is in common action, and driven gear 32a is pushed to feed gear wheel 32b one side by the elastic force of clutch spring 32d, and driven gear 32a and feed gear wheel 32b clip dull and stereotyped 32c and the one rotation.In case and driven gear 32a accepts the rotation of the 1st gear part 31, this rotation is delivered to the 3rd gear part 33 with regard to deceleration limit, limit from feed gear wheel 32b.
In addition, driven gear 32a and feed gear wheel 32b as mentioned above, owing to the elastic force of clutch spring 32d forms one.Therefore, when the revolving force that transmits is lower than the regulation torque, driven gear 32a just and feed gear wheel 32b one rotate.And when the revolving force that transmits was higher than the regulation torque, clutch 32d spring just skidded, and does not transmit its revolving force, the rotation of driven gear 32a discord feed gear wheel 32b one.
Adopt said structure, open and close member 4 because of manually to closing direction (arrow B direction among Fig. 1) action, liftout component 5 in Fig. 1 the arrow C direction, when being the inboard action of housing 8, the action of this liftout component 5 makes the spur gear 35 of the 3rd gear part 33 rotate to the arrow E direction, its power is delivered to feed gear wheel 32b and makes it to reverse, even so, when this revolving force is higher than the regulation torque, just can not be delivered to driven gear 32a.
In addition, with liftout component 5 to the place ahead by force pull out, liftout component 5 in Fig. 1 arrow D direction, when being the outside action of housing 8, the action of this liftout component 5 makes the spur gear 35 of the 3rd gear part 33 rotate to arrow F direction, its power is delivered to feed gear wheel 32b and makes it to reverse, even so, when this revolving force is higher than the regulation torque, just can not be delivered to driven gear 32a.That is, even when open and close member 4 is firmly closed or moved liftout component 5 to the place ahead one side by force, feed gear wheel 32b is just idle running also, can prevent the crown equivalent damage of each gear.In addition, the anti-locking mechanism of the overload of this 2nd gear part 32 can also make to stop at liftout component 5 return-to-home positions of jumping out the position in the time can not carrying out drive controlling to liftout component 5 owing to the fault of control device.
The 3rd gear part 33 be rotatably freely supported on the axle support that on housing, forms by: the two ends of rotary middle spindle and with the major diameter spur gear 35 of the feed gear wheel 32b engagement of the 2nd gear part 32, and be arranged on coaxial minor diameter cut-off wheel of the present invention 36 formations with this spur gear 35.These spur gears 35 and cut-off wheel 36 form one.
Cut-off wheel 36 is last levels of gear train 3, only rotates to single direction owing to the actuating force of motor 2.This cut-off wheel 36 can engage with the rack tooth 51a of the tooth bar 51 that forms on liftout component 5 or break away from.Below describe the engaging structure of 51 of this cut-off wheel 36 and tooth bars in detail.
36 parts in periphery of cut-off wheel form the 36a of tooth portion that engages with rack tooth 51a, and remainder then forms anodontia notch part 36b.Therefore, when the 36a of tooth portion of cut-off wheel 36 and tooth bar 51 were opposed, the 36a of tooth portion engaged with rack tooth 51a, and when notch part 36b and tooth bar 51 are opposed, just and between the rack tooth 51a broke away from snap-fit relationship.
In addition, the engagement between the rack tooth 51a of the 36a of tooth portion of cut-off wheel 36 and tooth bar 51 is the engagement between the identical tooth all the time.That is, as shown in Figure 3, the 1st tooth 36a1 and the tooth bar 51 in direction of rotation of cut-off wheel 36 mesh at the 1st rack tooth 51a1 of glide direction.
As shown in Figures 3 and 4, the axial length of the 1st tooth 36a1 of cut-off wheel 36 other tooth 36a later than the 2nd tooth is shorter.Therefore, when the engagement of 51 of cut-off wheel 36 and tooth bars begins, the 1st tooth 36a1 do not contact the 2nd rack tooth 51a2 and by with the position of rack tooth 51a2 at axial overlap, and passing through back and the 1st rack tooth 51a1 butt, meanwhile, follow-up the 2nd tooth 36a2 can with the 2nd rack tooth 51a2 butt.
That is, when tooth bar 51 engagements that make circular cut-off wheel 36 and linearity, if make each between cog positive engagement, will be in the swing-around trajectory L of the tooth 36a of circumferential notch gear 36, from the 2nd rack tooth 51a2 of configuration ahead of tooth bar 51 at moving direction.Therefore, the 1st tooth 36a1 of cut-off wheel 36 will contact with the 2nd rack tooth 51a2 before the 1st rack tooth 51a1 of contact tooth bar 51, caused and can not mesh smoothly.For this reason, conventional art is that the front end with the 2nd rack tooth 114a2 eliminates as shown in Figure 7, contacts with it with the 1st tooth 113a1 that avoids cut-off wheel 113, but so, can not effectively mesh between the 2nd tooth.
Thereby, engaging structure of the present invention is to make the tooth depth of cut-off wheel 36 and tooth bar 51 identical with other teeth, make cut-off wheel 36 the 1st tooth 36a1 can by with the 2nd rack tooth 51a2 of tooth bar 51 position at axial overlap, and engaging with the 1st rack tooth 51a1 of tooth bar 51 by the back, regulate the position of engagement between cut-off wheel 36 and the tooth bar 51 with this.
On the other hand, the tooth bar 51 that forms on liftout component 51 is configured to engage with above-mentioned cut-off wheel 36 disengaging state freely, and has the rack tooth 51a with the tooth 36a equal number of cut-off wheel 36.Longer at the 1st rack tooth 51a1 of these tooth bar 51 glide directions than the axial length of the 2nd later rack tooth 51a.Therefore, by with the 2nd rack tooth 51a2 at the 1st tooth 36a1 of the cut-off wheel 36 of the position of axial overlap butt with it.And the 1st rack tooth 51a1 is used for blocking the 1st tooth 36a1 at the cut-off wheel 36 of Fig. 2 downside by the 2nd rack tooth 51a2, determines the position of engagement between cut-off wheel 36 and the tooth bar 51 thus.
And behind butt between the 1st tooth 36a1, the 51a1, in case cut-off wheel 36 continues rotation along arrow F direction shown in Figure 1, tooth 36a and rack tooth 51a be engagement successively just, and meanwhile, tooth bar 51 gradually forwards (arrow D direction among Fig. 1) moves as straight line.At this moment, Nie He the number of teeth is this necessary number that slides of work, for example 3 simultaneously.
The tooth bar 51 that is formed with the liftout component 5 of above-mentioned tooth bar 51 meshes with the tooth portion of the cut-off wheel 36 of gear train 3 final levels, and accepts the actuating force of motor 2, slides to figure arrow D direction in 1 along guide rail 10 (see figure 2)s that form in housing 8 thus.This liftout component 5 is strip members, near the in its back-end tooth bar 51 that forms.And the part that has formed this tooth bar 51 is configured to the local overlapping state with integrally formed spur gear 35 on cut-off wheel 36.And in case local overlapping with this tooth bar 51 and spur gear 35, for example when constituting the position detecting device of tooth bar 51 and the 3rd gear part 33, just dispose this magnet etc. easily with magnet etc.
