Description
Technical field
The present invention relates to clutch mechanism and vehicle air exhaust port device, particularly about the improvement of the clutch mechanism between drive member and rotating driveshaft structure, and by containing the new construction of the vehicle air exhaust port device that such clutch mechanism constitutes.
Background technology
As everyone knows, be installed in the output system of propulsive effort of various devices and machinery etc. and the function that the clutch mechanism between the input system not only only has transmission of drive force as Poewr transmission mechanism, for example also has the function of cutting off propulsive effort according to exterior operation, reach the function etc. that the value of regulation is cut off propulsive effort when above with size, and be used as the device of transmission/cut-out propulsive effort at any time or stoped the safety device of the transmission of large driving force to be used widely at the propulsive effort that should transmit.
But, a kind of as in the device with such clutch mechanism, for example be useful on change to the indoor air-out of car towards vehicle air exhaust port device.In this air exhaust port device, generally in the peristome of the housing of the indoor opening of car, with around uprightly being arranged on the rotating driveshaft rotation in the housing or being equipped with one or more blades (wind direction parts) of different shape such as writing board shape in rotating mode, and at this rotating driveshaft be used to rotate between the drive member of the electro-motor that drives it and be provided with etc. clutch mechanism is installed.
Conduct like this, in the past is arranged on the mechanism that clutch mechanism on the vehicle air exhaust port device has proposed various structures.For example, in the clutch mechanism on being arranged at following patent documentation 1 disclosed air exhaust port device, comprising: reciprocating member, its propulsive effort by drive member moves back and forth; With suppress parts, be leaf spring that has the friction face that contacts with reciprocating member by friction force etc. based on the regulation elastic force pressure; But this suppresses parts and is bonded in the mode that one moves with respect to linkage part, and this linkage part links a plurality of blades mutually, can move back and forth one on the configuration direction of these blades and move.Like this, the big masterpiece time spent of friction force that produces on than the friction face that suppresses parts, allow to suppress relatively moving between parts and reciprocating member, and cut off the propulsive effort that transmits drive member to linkage part.In addition, the clutch mechanism of following patent documentation 2 disclosed air exhaust port devices comprises clutch components that is made of permanent magnet and the parts in opposite directions that are made of magnet, described clutch components is connected to any one in drive member and the linkage part, and described parts in opposite directions are connected to another and clutch components is adsorbed.Be used for clutch components and in opposite directions between the parts time at the masterpiece bigger, allow clutch components and relatively moving between parts in opposite directions, and cut off the propulsive effort that transmits drive member to linkage part than the adsorption affinity of clutch components.
Like this, in having the air exhaust port device in the past of such clutch mechanism, realized preventing clutch fading by friction force or adsorption affinity, automatically make the automatic operation of rotating driveshaft or blade rotation or rotation by the propulsive effort of drive member, and when the automatic operation of this rotating driveshaft or blade stops etc., by rotation (rotation of rotating driveshaft) with the power M/C blade bigger than friction force or adsorption affinity, can be easily by M/C change blow out air towards.
But as mentioned above, in the clutch mechanism on the air exhaust port device that is arranged in the past, power-transfer clutch load is based on the friction force that suppresses parts of leaf spring etc. or the adsorption affinity of the clutch components that is made of permanent magnet and constant magnitude.Therefore, if prevent the generation of the clutch fading when the automatic operation of rotating driveshaft or blade more reliably, and when setting power-transfer clutch load very big, utilize the operation load when manually making blade rotation (rotation of rotating driveshaft) to strengthen, cause the problem that operation feeling degenerates, on the other hand, if make power-transfer clutch load little, then when the automatic operation of rotating driveshaft or blade, be easy to generate clutch fading, and the propulsive effort of the drive member of transmitting to linkage part is insufficient.
Under this situation, in order to address the above problem, in following patent documentation 3, the clutch mechanism that following patent documentation 2 disclosed devices has been carried out improved air exhaust port device is disclosed.That is, here, the clutch components that constitutes clutch mechanism constitutes by electromagnet with its one stack-mounted magnetic substance.In view of the above, when the automatic operation of rotating driveshaft or blade, by strengthening the excitation power of the clutch components that constitutes by electromagnet, increased power-transfer clutch load, prevented clutch fading effectively, therefore, the propulsive effort of drive member can fully and stably transmit with respect to linkage part.In addition, during the M/C of blade (rotating driveshaft), by weakening the excitation power of clutch components, and reduce power-transfer clutch load, the operation load of blade (rotating driveshaft) also reduces, and its result can access good operation feeling.
But, in such clutch mechanism in the past, because clutch components is made of electromagnet, so compare clutch components and then be that the whole cost of clutch mechanism increases with the device before this that obtains power-transfer clutch load based on the adsorption affinity of friction force that suppresses parts or permanent magnet.And, for the excitation power of control clutch parts, the control setup different with the control setup of the drive controlling of carrying out drive member must be arranged also, its result, device single-piece manufacturing cost rises, and more can not avoid the complexity of its structure, in these areas, still there is room for improvement.

In view of the above, moving body 68 can make circular-arc engagement section 70 from the outstanding laterally position of the peristome of tubular support 56, and the elastic force pressure of opposing compression coil spring 76 and circular-arc engagement section 70 is pulled between the position in the tubular support 56, one side is by each guiding groove 66 guiding of tubular support 56, and one side moves.Meanwhile, it constitutes as this moving body 68: when the crank motion that carries out owing to the driving of not shown stepping motor along with crank motion plate 28, make gear part 54 around S. A. 44 rotations, thereby make the unitary rotation of rotor 46, at this moment, moving body 68 can rotate integratedly with tubular support 56.
In addition, as Fig. 3 and shown in Figure 6, on this rotor 46, the driven wheel 50 that is stacked with the state that is clipped between downside swivel 48 and the upside swivel 52 only has in the part of 1/2 outer peripheral face roughly and a plurality of wheels tooth is set and the horizontal gear form of the hypodontia that constitutes.Like this, the circumferencial direction central portion of the roughly 1/2 outer peripheral face part that wheel tooth is not set in this driven wheel 50 is provided with recess 60.In addition, as this recess 60, its bottom surface becomes contact surface 61, this contact surface 61 be with moving body 68 in the cooresponding arc surface shape of front end face of circular-arc engagement section 70, and the face portion (lateral parts) of circumferencial direction both sides that is positioned at the outer peripheral face of driven wheel 50 become respectively to cross one another two that radially extend, as the first snap-latch surface 62a and the second snap-latch surface 62b of first engagement section.
In addition, wheel tooth in the end faces of both sides up and down of driven wheel 50 forms on the peripheral part of side part, upright integratedly respectively be provided with each one the pole form with specified altitude, as the engagement pin 63 (with reference to Fig. 5) of second engagement section.Like this, the engagement pin 63 (among Fig. 6 shown in the long and two-short dash line) that is arranged on the upper surface of driven wheel 50 is provided in the distolateral position of the hand of rotation front side of the right-hand rotation (cw commentaries on classics) among in the peripheral part that gear in the driven wheel 50 forms the side part, driven wheel 50, Fig. 6.In addition, the engagement pin 63 (among Fig. 6 shown in the dotted line) that is arranged on the lower surface of driven wheel 50 is provided in the distolateral position of the hand of rotation front side of the left-hand rotation (conter clockwise commentaries on classics) among in the peripheral part that gear in the driven wheel 50 forms the side part, driven wheel 50, Fig. 6.
So such driven wheel 50 is by downside swivel 48, the state with the gear part 54 that is stacked in rotor 46 can be installed on the S. A. 44 with the relative rotation with respect to rotor 46.In addition, driven wheel 50 is under the state that is installed on S. A. 44 like this, with transmission gear 65 engagements as first gear, but these transmission gear 65 one are installed in the bottom of the installation shaft of A lower side wall portion in the installation shaft 22 of described vertical blade 18, that run through housing 14 rotatably, have, the tubular support 56 interior outstanding circular-arc engagement sections 70 from rotor 46 in the moving body 68 are charged in the recess 60 again.So, protrude into the elastic force pressure of circular-arc engagement section 70 by the compression coil spring 76 in the tubular support 56 that is housed in rotor 46 in this recess 60, contact with contact surface 61 pushings of recess 60, and engage with the first snap-latch surface 62a and the second snap-latch surface 62b respectively, this the first snap-latch surface 62a and the second snap-latch surface 62b are clipped in circular-arc engagement section 70 therebetween, are positioned at the circumferencial direction both sides of driven wheel 50.
On the other hand, as Fig. 3 and shown in Figure 7, be stacked on downside swivel 48 between driven wheel 50 and the rotor 46 and be the drum that has than the little external diameter of gear part 54 given sizes of rotor 46 and thicker wall thickness and lower height on the whole.Like this, in the outer peripheral face of the upper end of this downside swivel 48, mutually be adjacently located on Zhou Fangxiang, roughly account on two positions of quarter turn, stopper portions 78 is set integratedly and as the slip large-diameter portion 80 of pushing portion respectively.
Promptly, stopper portions 78 is long platy morphology on the whole, is formed on the position at the front side of the hand of rotation that described circumferencial direction is two adjacent positions, downside swivel 48, Fig. 7 turns left of the outer peripheral face of the upper end that is arranged in downside swivel 48.In addition, though as described later, downside swivel 48 contacts with the circular-arc engagement section 70 of moving body 68 at its outer peripheral face,, stopper portions 78 is extended as the crow flies towards at the opposition side with respect to another position side on the rectangular direction of the moving direction of this moving body 68, adjacent.
On the other hand, slip large-diameter portion 80 is a part Circular Plate shape, this part Circular Plate shape by in the outer peripheral face of the external diameter of downside swivel 48 and driven wheel 50, that be formed with recess 60, external diameter than the external diameter of the outer peripheral face part that does not have wheel tooth only the roughly quarter turn of the Circular Plate of big given size partly constitute.Then, to prolong the roughly mode of 1/4 girth at circumferencial direction, be formed on the position of rear side of described two positions, downside swivel 48, the hand of rotation that Fig. 7 turns left of the upper end outer peripheral face that is arranged in downside swivel 48.
In addition, here, front side at two sides, downside swivel 48, the hand of rotation that Fig. 7 turns left of the circumferencial direction both sides that are arranged in the tabular slip large-diameter portion 80 of described part annulus, the side that promptly is positioned at the formation side of stopper portions 78 becomes sliding surface 82, and becomes snap-latch surface 84 as the 3rd engagement section with the side of its opposition side.Like this, the snap-latch surface 84 in these sliding surfaces 82 and the snap-latch surface 84 is made of the plane in the straight extension of direction radially of downside swivel 48.On the other hand, sliding surface 82 is made of smooth dip plane, the ora terminalis position of the formation side of the stopper portions 78 of this dip plane from the circumferencial direction of the outer peripheral face of slip large-diameter portion 80 is towards interior all sides of downside swivel 48, to extending obliquely than the formation side of the more close stopper portions 78 in the center of downside swivel 48.
Have again, the integral body of the outer peripheral face of slip large-diameter portion 80 becomes the pushing face 85 that is made of arc surface, in addition, in such pushing face 85, be positioned at sliding surface 82 sides more close than its circumferencial direction central portion, promptly the part of the formation side of stopper portions 78 is formed with engaging recessed part 86.And this engaging recessed part 86 has the more shallow degree of depth, and its interior shape is the cooresponding arc surface shape of circular-arc front end face in the circular-arc engagement section 70 with moving body 68.
So such downside swivel 48 can be installed on the S. A. 44 with rotor 46 or driven wheel 50 with the relative rotation with the state on the binding board 58 in the gear part 54 that is stacked in rotor 46.In addition, under such state, as downside swivel 48, the circular-arc engagement section 70 of giving prominence in the tubular support 56 of the rotor 46 from described moving body 68 is according to the elastic force pressure pushing contact outer peripheral face part of compression coil spring 76, engage with the sliding surface 82 of slip large-diameter portion 80, this outer peripheral face part is in the part that is sandwiched between stopper portions 78 and the slip large-diameter portion 80, have again, the described engagement pin 63 that is arranged at the lower surface of driven wheel 50 is configured to when driven wheel 50 turns left rotation, engage with the snap-latch surface 84 of slip large-diameter portion 80, to push this snap-latch surface.
In addition, from Fig. 3 and Fig. 8 as can be seen, with driven wheel 50 is clipped in its with downside swivel 48 between state and the upside swivel 52 that is stacked has shape and the structure identical with downside swivel 48.That is, upside swivel 52 also is to be the drum that has than the little external diameter of gear part 54 given sizes of rotor 46 and thicker wall thickness and lower height on the whole.Like this, in the outer peripheral face of the bottom of this upside swivel 52, mutually be adjacently located on circumferencial direction, roughly account on two positions of quarter turn, stopper portions 78 and slip large-diameter portion 80 are set respectively integratedly.In addition, these stopper portions 78 and slip large-diameter portion 80 have be arranged on downside swivel 48 on stopper portions 78 shape and the structure identical with slip large-diameter portion 80, the side, both sides of slip large-diameter portion 80 becomes sliding surface 82 and snap-latch surface 84 respectively, and the outer peripheral face of slip large-diameter portion 80 becomes pushing face 85, have again, engaging recessed part 86 is set on this pushing face 85.
And, in this upside swivel 52, opposite in the formation position in the circumferencial direction of stopper portions 78 and slip large-diameter portion 80 and the downside swivel 48.Promptly, the position of the front side of hand of rotation in two positions of the adjacent roughly quarter turn of the circumferencial direction of the outer peripheral face of the bottom of upside swivel 52, right-hand rotation upside swivel 52, that be arranged in Fig. 8, form stopper portions 78, and, form slip large-diameter portion 80 at the position of the rear side that is positioned at this hand of rotation.In addition, corresponding, the side of the front side of hand of rotation in two sides of slip large-diameter portion 80, that be positioned at right-hand rotation becomes sliding surface 82, and the side that is positioned at its opposition side becomes snap-latch surface 84.
So such upside swivel 52 rotatably is installed on the S. A. 44 with respect to driven wheel 50 or rotor 46, downside swivel 48 with the state that is stacked on the driven wheel 50.In addition, under such state, even as upside swivel 52, it also is the elastic force pressure that passes through compression coil spring 76 from the tubular support 56 interior outstanding circular-arc engagement sections 70 of rotor 46 in the described moving body 68, face contact is sandwiched in the outer peripheral face part between stopper portions 78 and the slip large-diameter portion 80, engage with the sliding surface 82 of slip large-diameter portion 80, have again, the described engagement pin 63 that is arranged on the lower surface of driven wheel 50 is configured to when driven wheel 50 is turned right rotation, engage with the snap-latch surface 84 of slip large-diameter portion 80, so that it is pushed.
Like this, in the present embodiment, as Fig. 9 and shown in Figure 10, drive the crank motion that carries out because of the rotation of stepping motor according to crank motion plate 28, when the integral body of rotor 46 is rotated around S. A. 44, first snap-latch surface 62a of the recess 60 in the driven wheel 50 or second snap-latch surface 62b quilt push to the rotation direction front side of rotor 46 and moving body 68 with the circular-arc engagement section 70 of the moving body 68 of rotor 46 unitary rotation, in view of the above, driven wheel 50 to the identical direction of rotation direction of rotor 46 and moving body 68, with the corresponding rotation amount rotation of their amount of spin.So, be accompanied by the rotation of such driven wheel 50, but the installation shaft 22 that the vertical blade 18 of this transmission gear 65 is installed rotatably with its ingear transmission gear 65 and one is rotated to the direction opposite with the hand of rotation of this driven wheel 50, in view of the above, have this installation shaft 22 vertical blade 18, also have all vertical blades 18 to rotate at left and right directions with its interlock.
As mentioned above, here, it constitutes: the propulsive effort of drive member is passed to the installation shaft 22 of indulging blade 18 by clutch mechanism 30, carries out rotating automatically together of a plurality of vertical blades 18, and so, air automatically changes to the indoor blow-off direction of car.Like this, inside at clutch mechanism 30, the first snap-latch surface 62a of the recess 60 in the circular-arc engagement section 70 of moving body 68 and the driven wheel 50 or the second snap-latch surface 62b engage and rotate, in view of the above, realized from the transmission of the input side of propulsive effort to outgoing side, therefore, for example compare, between moving body 68 and driven wheel 50, produce clutch fading in the time of can advantageously preventing the rotating automatically together of vertical blade 18 with the structure of transmission by the such propulsive effort of realizations such as friction force.
And, as mentioned above when a plurality of vertical blades 18 rotate together automatically, when rotor 46 and driven wheel 50 right-hand rotation rotations or rotation, as shown in Figure 9, the snap-latch surface 84 of the slip large-diameter portion 80 in the upside swivel 52 is set at the engagement pin 63 of upper surface of driven wheel 50 to the rotation of driven wheel 50 or rotor 46 or the pushing of rotation direction front side.In addition, sliding surface 82 quilts of the slip large-diameter portion 80 in the downside swivel 48 push to the rotation direction front side of rotor 46 and moving body 68 with the circular-arc engagement section 70 of the moving body 68 of rotor 46 unitary rotation.In view of the above, upside swivel 52 and downside swivel 48 to the rotation or the identical right-hand rotation direction of hand of rotation of rotor 46, moving body 68 or driven wheel 50, with their rotation or the corresponding rotation amount rotation of rotation amount.
On the other hand, when rotor 46 and automatic left rotation of driven wheel 50 or rotation, as shown in figure 10, sliding surface 82 quilts of the slip large-diameter portion 80 in the upside swivel 52 push to the rotation direction front side of rotor 46 and moving body 68 with the circular-arc engagement section 70 of the moving body 68 of rotor 46 unitary rotation.In addition, the snap-latch surface 84 of the slip large-diameter portion 80 in the downside swivel 48 be set at driven wheel 50 lower surface engagement pin 63 to the rotation of driven wheel 50 or rotor 46 or the pushing of rotation direction front side.In view of the above, upside swivel 52 and downside swivel 48 to the rotation or the identical left-hand rotation direction of hand of rotation of rotor 46, moving body 68 or driven wheel 50, with their rotation or the corresponding rotation amount rotation of rotation amount.
In addition, here, when upside swivel 52 right-hand revolutions as shown in Figure 9, when downside swivel 48 anti-clockwise rotations as shown in figure 10, these upsides and downside swivel 52,48 stopper portions separately 78, limited projection 88a by fastening in rotation, on the 88b, this rotation restriction projection 88a, 88b is with at upside and downside swivel 52,48 the mode of radially extending is integrally formed at each swivel 52 that clips in the described housing 38 respectively one by one, 48 and be positioned at the position of the left and right sides, in view of the above, in such catch positions, the right-hand revolution of the anti-clockwise rotation of downside swivel 48 and upside swivel 52 is stoped respectively.
Like this, for example as shown in Figure 6, be positioned at the midway location of slewing area at rotor 46, each vertical blade 18 is positioned at the position towards the fore-and-aft direction that is parallel to the car chamber, the rotation of driving component of stepping motor etc. drives under the state that stops, and described operation knob 27 is slided when mobile, as shown in figure 11 to right, the installation shaft 22 and transmission gear 65 anti-clockwise rotations of vertical blade 18 are with transmission gear 65 ingear driven wheels 50 right-hand revolutions.So, the snap-latch surface 84 that is arranged on the slip large-diameter portion 80 in engagement pin 63 and the upside swivel 52 of upper surface of driven wheel 50 contacts, this snap-latch surface 84 is by the hand of rotation front side pushing of this engagement pin 63 to driven wheel 50, in view of the above, upside swivel 52 and driven wheel 50 one anti-clockwise rotation together.And at this moment, downside swivel 48 is without any rotation.
In addition, at this moment, because stop because rotation of driving component drives, as mentioned above, rotor 46 and also become by the moving body 68 of its supporting and to rotate the state stop is so shown in long and two-short dash line among Figure 11, along with the rotation of upside swivel 52, the sliding surface 82 of the slip large-diameter portion 80 in the upside swivel 52 is charged in the recess 60 of driven wheel 50, with contact surface 61 contact positions on the outer peripheral face of circular-arc engagement section 70 of moving body 68 slide.In view of the above, circular-arc engagement section 70 is pushed towards the direction of separating from contact surface 61, and therefore, moving body 68 is in order to break away from the recess 60 of driven wheel 50, and the elastic force pressure of opposing compression coil spring 76 is drawn into mobile (retreating) gradually in the tubular support 56 of rotor 46.
Then, if upside swivel 52 further right-hand revolutions, then shown in Figure 11 solid line, move to as the circular-arc engagement section 70 of charging into the position in recess 60 of moving body 68 on the pushing face 85 of slip large-diameter portion 80 of upside swivel 52, by elastic force pressure pushing contact this pushing face 85 of compression coil spring 76.So, because the diameter of the slip large-diameter portion 80 of upside swivel 52 is bigger than the external diameter of the outer peripheral face part that is formed with recess 60 of driven wheel 50, so the integral body of moving body 68 breaks away from the recess 60 of driven wheel 50, be positioned at the position of drawing in of the tubular support 56 that is drawn into rotor 46, simultaneously, keep this state, in view of the above, the circular-arc engagement section 70 of moving body 68 is removed fully with respect to the first and second snap-latch surface 62a of recess 60, the engaging of 62b.So, under such state, the slide that driven wheel 50 and transmission gear 65 and installation shaft 22 can be by operation knobs 27, with very little operation load easily to the left and right twocouese be rotated operation.
In addition, here, as mentioned above, under the state that the engaging of the circular-arc engagement section 70 of the first and second snap-latch surface 62a, the 62b of recess 60 and moving body 68 is disengaged, the stopper portions 78 of upside swivel 52 contacts with the rotation of housing 14 restriction projection 88a, stops upside swivel 52 further right-hand revolutions.From this point as can be seen,, constitute the rotation limiting member here by the stopper portions 78 of upside swivel 52 and the rotation restriction projection 88a that is in contact with it.
In addition, on the pushing face 85 as if the slip large-diameter portion 80 that moves to upside swivel 52, then the front end of the circular-arc engagement section 70 of moving body 68 is charged in the engaging recessed part 86 that is arranged on this pushing face 85, and the elastic force pressure pushing by compression coil spring 76 is contacted with its bottom surface.In view of the above, for example, by acting on the thrust pressure of pushing face 85 from the circular-arc engagement section 70 of moving body 68, between them, produce to skidding of circumferencial direction etc., prevent to produce the useless rotation that upside swivel 52 turns left.Like this, can advantageously prevent to engage once more with the first and second snap- latch surface 62a, 62b because the useless anti-clockwise rotation of this upside swivel 52 protrudes in the recess 60 of driven wheel 50 circular-arc engagement section 70.
On the other hand, as shown in Figure 6, be positioned at the midway location of slewing area at swivel 46, rotation of driving component drives under the state that stops, make in order to make each vertical blade 18 turning clockwise operation knob 27 left direction slide when mobile, as shown in figure 12, the installation shaft 22 and transmission gear 65 right-hand revolutions of vertical blade 18, driven wheel 50 turns left to rotate.So, the snap-latch surface 84 that is arranged on the slip large-diameter portion 80 in engagement pin 63 and the downside swivel 48 of lower surface of driven wheel 50 contacts, this snap-latch surface 84 is by the hand of rotation front side pushing of this engagement pin 63 to driven wheel 50, in view of the above, downside swivel 48 and driven wheel 50 anti-clockwise rotation integratedly together.In addition, at this moment, upside swivel 52 is without any rotation.
Then, at this moment, different with hand of rotation, upside swivel 52 is identical during by manual one right-hand revolution with driven wheel 50, shown in long and two-short dash line among Figure 12 and solid line, the circular-arc engagement section 70 of moving body 68 is pushed by the sliding surface 82 with the downside swivel 48 that slides with respect to it, for disengaging in the recess 60 of driven wheel 50, and the elastic force pressure of opposing compression coil spring 76 is drawn into mobile (retreating) gradually in the tubular support 56 of rotor 46.In addition, if along with downside swivel 48 further anti-clockwise rotations, the pushing face 85 of the slip large-diameter portion 80 of downside swivel 48 is stepped up in the circular-arc engagement section 70 of moving body 68, then moving body 68 integral body break away from the recess 60 of driven wheel 50, in view of the above, the circular-arc engagement section 70 of moving body 68 is removed fully with respect to the first and second snap-latch surface 62a of recess 60, the engaging of 62b.So under such state, driven wheel 50 and transmission gear 65 and installation shaft 22 can be by the slides of operation knob 27, with very little operation load, easily twocouese is rotated operation to the left and right.
And, even under the state that the engaging of the circular-arc engagement section 70 of the first and second snap-latch surface 62a, the 62b of recess 60 and moving body 68 is disengaged, the stopper portions 78 of downside swivel 48 and the rotation restriction projection 88b contact that is different from the rotation restriction projection 88a that upside swivel 52 contacted, in view of the above, stop downside swivel 48 further anti-clockwise rotations.From this point as can be seen, in the present embodiment,, constitute the rotation limiting member by the stopper portions 78 of downside swivel 48 and the rotation restriction projection 88b that is in contact with it.
In addition, if the pushing face 85 of the slip large-diameter portion 80 of downside swivel 48 is stepped up in the circular-arc engagement section 70 of moving body 68, the front end of then circular-arc engagement section 70 is charged into and is positioned at the engaging recessed part 86 that is arranged on this pushing face 85.At this moment, it constitutes: the circular-arc engagement section 70 of moving body 68 is contacted with the inner face of engaging recessed part 86 by the elastic force pressure pushing of compression coil spring 76, in view of the above, can advantageously prevent to produce downside swivel 48 left-handed turning rotation invalidly, further advantageously prevent because the anti-clockwise rotation invalidly of described downside swivel 48, circular-arc engagement section 70 is protruded in the recess 60 of driven wheel 50, engage once more with the first and second snap- latch surface 62a, 62b.
In addition, here, as shown in figure 11, in the engaging recessed part of charging into from the circular-arc engagement section 70 of moving body 68 on the pushing face 85 that is arranged at upside swivel 52 86, the recess 60 interior states that break away from from driven wheel 50, stepping motor rotates driving once more, then the further right-hand revolution owing to upside swivel 52 is prevented from, so at moving body 68 and rotor 46 together during turning clockwise, the circular-arc engagement section 70 of this moving body 68 breaks away from engaging recessed part 86, and protrudes in the engaging recessed part 86 of downside swivel 48.Like this, if from this state, moving body 68 turns left, and then downside swivel 48 is also with moving body 68 anti-clockwise rotations.At this moment, circular-arc engagement section 70 engages with the sliding surface 82 of upside swivel 52, and upside swivel 52 is also with moving body 68 or downside swivel 48 anti-clockwise rotation integratedly.In addition, in view of the above, the engagement pin 63 that is arranged on the upper surface of driven wheel 50 is pushed by the snap-latch surface 84 left-handed turning directions of downside swivel 48, and driven wheel 50 is anti-clockwise rotation also.So, in such rotation or rotate in the process carry out continuously, when the stopper portions 78 by downside swivel 48 stops the anti-clockwise rotation of downside swivel 48 with rotation restriction projection 88b, the circular-arc engagement section 70 of moving body 68 breaks away from engaging recessed part 86, elastic force pressure by compression coil spring 76 protrudes in the recess 60 of driven wheel 50 (contact surface 61 towards recess 60 advances), engages once more with the first and second snap-latch surface 62a, 62b.So, driven wheel 50 in view of the above, begins the automatic rotation of a plurality of vertical blades 18 once more with rotor 46 or moving body 68 one rotation once more.In addition, as shown in figure 12, in engaging recessed part 86 on the pushing face 85 that is arranged at downside swivel 48 is charged in the circular-arc engagement section 70 of moving body 68, the recess 60 interior states that break away from from driven wheel 50, stepping motor rotates when driving once more, also, begin the automatic rotation of a plurality of vertical blades 18 once more with above-mentioned same.
As mentioned above, in the present embodiment, under the halted state that the rotation of driving component of stepping motor etc. drives, when the operation knob 27 of slide by manually making vertical blade 18 and rotate, make the downside swivel 48 that can be installed in the relative rotation on the S. A. 44 or any one and driven wheel 50 rotations, the easily installation shaft 22 and the transmission gear 65 of the vertical blade 18 of rotary manipulation in the upside swivel 52 with very little operation load only simply.And, here, by only resisting the elastic force pressure of compression coil spring 76, or by this elastic force pressure, the travel mechanism that give prominence to/draws in mobile moving body 68 is combined to the so extremely simple and cheap construction of gear mechanism, can realizes the above-mentioned manually operated operation load that alleviates vertical blade 18 effectively.
Therefore, vehicle air exhaust port device as so relevant present embodiment, when vertical blade 18 rotates simultaneously automatically, can simultaneously advantageously prevent the generation of the clutch fading in the clutch mechanism 30, one side is stably transmitted the propulsive effort of drive member to vertical blade 18, indulge the automatic rotating operation of blade 18 reliably, simultaneously, can be little with operation load, good operation feeling, easily carry out the manual rotation operation that the operation knob 27 by vertical blade 18 carries out, and these can realize by low cost and the simple structure of trying one's best extremely beneficially.So,, can bring into play the excellent operation and the usability that in device in the past, can't obtain eventually extremely effectively as its result.
In addition, in the present embodiment, for example be positioned at the midway location of slewing area at rotor 46, each vertical blade 18 is positioned at towards the fore-and-aft direction position that is parallel to the car chamber, rotation of driving component drives under the state that stops, slide in the direction to the left and right of passing through operation knob 27, driven wheel 50 is left or during right rotation, by the rotation of any one party in downside swivel 48 and the upside swivel 52, the circular-arc engagement section 70 that can remove moving body 68 fully is with respect to the first and second snap-latch surface 62a of recess 60, the engaging of 62b.Therefore, direction slide operation knob 27 arbitrarily to the left and right can both be rapidly and obtain alleviating the effect of operation load effectively.
