(structure of rotor)
Fig. 4 (a) and (b) are the expression vertical view of having used the rotor of the stepper motor that uses in the portable seat lifting device of the present invention, and the summary sectional view of the D-D ' line of Fig. 4 (a).
Magnet rotary body 75 comprises shown in Fig. 4 (b): outer wall is fixed with the 75b of urceolus portion that magnet 75a and inwall form the concavo-convex 75e of tooth portion; Be configured in the inboard of the 75b of this urceolus portion and the inner cylinder portion 75c of inwall and fixed axis 78 (with reference to Fig. 3 (b)) slip; And the connecting portion 75d that this inner cylinder portion 75c is connected with the 75b of urceolus portion one.
On the other hand, pinion rotary body 74 has the 74b of tube portion that the outer wall of the inner cylinder portion 75c of inwall and magnet rotary body 75 slides, upside at the outer wall of the 74b of this forms pinion 74a, and the arm of ratchet 74c that extends agley from downside along this outer wall is to outstanding shaping of W direction of Fig. 4 (a) simultaneously.The front end of this arm of ratchet 74c becomes the claw 74d that engages with the concavo-convex 75e of tooth portion that inwall at the 75b of urceolus portion of magnet rotary body 75 forms.Therefore, this claw 74d by arm of ratchet 74c radially under the state of the application of force with the 75e of tooth portion butt.That is, in this form, constitute the ratchet mechanism 79 of torque limiter by arm of ratchet 74c and the 75e of tooth portion.In this form, used ratchet mechanism 79, but be not limited to ratchet mechanism 79, can use various torque limiters as torque limiter.
In the ratchet mechanism 79 of this form, toilet seat assembly 10 when ascent direction drives, is for example taken toilet seat assembly 10 and when toilet seat assembly 10 applied the excessive load of descent direction, stepper motor 7 can imbalance by mistake.That is, when the descent direction effect of toilet seat assembly 10 has excessive load, the idling torque of ratchet mechanism 79 (hereinafter referred to as following direction idling torque) is bigger than the reverse imbalance torque of stepper motor 7.Therefore, this occasion, the 75f of wall portion of claw 74d and the 75e of tooth portion is fastened under the state that is maintained, stepper motor 7 imbalances, the rotor 76 of stepper motor 7 rotates at a high speed to the W direction.
On the other hand, in the ratchet mechanism 79 of this form, with toilet seat assembly 10 when descent direction drives, for example, mistake is taken toilet seat assembly 10 and when toilet seat assembly 10 applied the excessive load of descent direction, pinion rotary body 74 was with respect to 75 idle running of magnet rotary body.That is, following direction idling torque is littler than the forward imbalance torque of stepper motor 7.Therefore, this occasion, before stepper motor 7 imbalances, claw 74d frees with the engaging of the 75f of wall portion of the 75e of tooth portion.
Stepper motor 7 imbalances, the magnet rotary body 75 of stepper motor 7 rotates at a high speed on one side to the W direction on one side that toilet seat assembly 10 descends, and the idling torque (hereinafter referred to as last direction idling torque) of the ratchet mechanism 79 when toilet seat assembly 10 arrives upper/lower positions is littler than following direction idling torque.Upward the direction idling torque is set at driving mechanisms 5 such as reduction gearing row 70 and slide block 51 and does not produce breakage, when even event toilet seat assembly 10 stops, do not have undue load yet and act on the driving mechanisms 5 such as reduction gearing row 70 and slide block 51, can prevent the breakage of driving mechanism.
(explanation of the lifting action of toilet seat)
Fig. 5 (a) and (b) are to be illustrated in the key diagram that the movable link of having used in the portable seat lifting device of the present invention, having put the toilet seat assembly is in the state of upper/lower positions, and movable link is in the key diagram of uppermost position in fig-ure.And Fig. 5 (a) and (b) are equivalent to the cross section of the A-A ' line of Fig. 2 (a).
The portable seat lifting device 1 of this form is the upper surface portion that fixed head 2 is fixed on toilet seat body 11 (with reference to Fig. 1), and the state that toilet seat assembly 10 is installed on the upper surface 60 of movable platen 6 uses down.
Shown in Fig. 5 (a), begin before cleaning waits, toilet seat 12 is in the upper surface of closet body 11, and toilet seat assembly 10 and movable platen 6 are in upper/lower positions.Under this state, the leading section of fastened component 95 engages with the downside recess 97 of the vertical plane 22 of fixed head 2, plays the effect of the 1st block 91.Therefore, at this upper/lower positions, because the braking torque of the engaging power at the 1st block 91 places, stepper motor 7 and the deadweight of toilet seat assembly 10, so can not cause the 10 casual risings of toilet seat assembly.In addition, under this state, potential difference meter 14 output expression toilet seat assemblies 10 are in upper/lower positions.
When this state floated toilet seat assembly 10, when the switch motion of having carried out regulation, then stepper motor 7 rotated towards positive direction with the step number or the official hour of regulation in order to begin cleaning.Its result, the power that rotatablely moves of stepper motor 7 is passed to output pinion 80 by reduction gearing row 70, and shown in Fig. 5 (b), output pinion 80 rises right side slide block 51 by tooth bar 53.Therefore, remove in the engaging at the 1st block 91 places, left slider 52, movable platen 6 and toilet seat unit 10 rise with right side slide block 51 one.
After toilet seat assembly 10 is risen, stop stepper motor 7.During this period, the pinion 82 turn-sensitive device gears 15 of output gear 8, the output of potential difference meter 14 changes, so just can detect the position that toilet seat assembly 10 has risen to regulation from its output.In addition, toilet seat assembly 10 has risen to this situation of assigned position, also can inform by the click sound that the 2nd block 92 places produce.And toilet seat assembly 10 is under the state that uppermost position in fig-ure stops, and by the engaging power at the 2nd block place and the braking torque of stepper motor 7, toilet seat assembly 10 can not fall down because of deadweight.
On the other hand, when wanting to make toilet seat assembly 10 to descend after cleaning finishes, if the switch motion of stipulating under the state shown in Fig. 5 (b), then stepper motor 7 carries out reverse rotation with the step number or the official hour of regulation.Its result, the power that rotatablely moves of stepper motor 7 is passed to output pinion 80 by reduction gearing row 70, and shown in Fig. 5 (a), output pinion 80 descends right side slide block 51 by tooth bar 53.Therefore, remove in the engaging at the 2nd block 92 places, left slider 52, movable platen 6 and toilet seat unit 10 descend with right side slide block 51 one.
After toilet seat assembly 10 is descended, stop stepper motor 7.During this period, the pinion 82 of output gear 8 makes sensor gear 15 reverse rotations, and the output of potential difference meter 14 changes, so just can detect the position that toilet seat assembly 10 has dropped to regulation from its output.In addition, toilet seat assembly 10 has dropped to this situation of assigned position, also can inform by the click sound that the 1st block 91 places produce.
(action specification of ratchet mechanism)
In this form, when toilet seat assembly 10 was floated, magnet rotary body 75 rotated to the V direction shown in Fig. 4 (a).Therefore, the 75f of the wall portion side butt of the circumferencial direction of the claw 74d of pinion rotary body 74 and the 75e of tooth portion, pinion rotary body 74 are followed 75 rotations of magnet rotary body.Here, when the excessive load that toilet seat assembly 10 has been applied descent direction, as mentioned above, the following direction idling torque of ratchet mechanism 79 is bigger than the reverse imbalance torque of stepper motor 7, so rotor imbalance and rotating at a high speed to the W direction.
In addition, also little when being sitting on the toilet seat assembly 10 when stopping under the float state because of the braking torque ratio inverse imbalance torque of stepper motor 7 by mistake, so with described identical, rotor 76 is lacked of proper care and is rotated at a high speed to the W direction.
Like this, with toilet seat assembly 10 when floating that mistake is sat in the direction driving process or mistake when being sitting on the toilet seat assembly 10 when stopping under the float state, Yi Bian rotate, make toilet seat assembly 10 to drop to closet body 11 at a high speed towards the W direction on one side because of rotor 76 imbalances.
Subsequently, after toilet seat assembly 10 arrives upper/lower positions, stop at the upper surface of closet body 11.Ratchet rotary body 74 also stops thereupon.On the other hand, at a high speed the inertia force of the W direction that causes of rotation acts on magnet rotary body 75, thus magnet rotary body 75 rotate to the W direction, the result shown in Fig. 4 (a), the 75g of the wall portion side butt of claw 74d and the 75e of tooth portion.
Under the state of claw 74d and the 75g of wall portion butt, inertia further acts on magnet rotary body 75, and when based on the torque of this inertia force during greater than the last direction idling torque of ratchet mechanism 79, then magnet rotary body 75 begins idle running.That is, arm of ratchet 74c deflection to the inside, claw 74d crosses the 75g of wall portion, allows the rotation of magnet rotary body 75.
On the other hand, when toilet seat assembly 10 was descended, magnet rotary body 75 rotated towards the W direction shown in Fig. 4 (a).Therefore, the 75g of the wall portion side butt of the circumferencial direction of the claw 74d of pinion rotary body 74 and the 75e of tooth portion, pinion rotary body 74 are followed 75 rotations of magnet rotary body.Here, when toilet seat assembly 10 had been applied the excessive load of descent direction, as mentioned above, the following direction idling torque of ratchet mechanism 79 was less than the forward imbalance torque of stepper motor 7, so before stepper motor 7 imbalances, claw 74d frees with the engaging of the 75f of wall portion of the 75e of tooth portion.Therefore, under the state of pinion rotary body 74 with respect to magnet rotary body 75 idle running, toilet seat assembly 10 continues to descend, and stops when arriving upper/lower positions.
(effect of this form)
More than explanation is such, in the portable seat lifting device 1 of this form, constituted the driving mechanism 5 that makes movable platen 6 that toilet seat assembly 10 has been installed rise and descend by electronic, so during the depth of cleaning closet body 11 and toilet seat 12 soffits inboard, do not need to lift or put down toilet seat assembly 10 with hand.Therefore, the burden in the time of can alleviating the cleaning Western water closet.
In addition, make the reverse imbalance moment of torsion of the following direction idling torque of ratchet mechanism 79, thereby magnet rotary body 75 produces the imbalance rotation because of overload greater than stepper motor 7 owing to constitute.So magnet rotary body 75 transmits the load make the direction that toilet seat assembly 10 descends till the imbalance, can fully use the transmission capacity of stepper motor 7.Therefore, use the stepper motor 7 of low output, realize the miniaturization of stepper motor 7.And, for the inertia force of magnet rotary body 75 of the rotation of lacking of proper care because of overload, cut off being connected of stepper motor 7 and toilet seat assembly 10 by ratchet mechanism 79, so can prevent the breakage of driving mechanism 5.
And, because it is littler than positive direction imbalance moment of torsion to constitute the following direction idling torque that makes ratchet mechanism 79, so for magnet rotary body 75 with the overload of toilet seat assembly 10 when the decline direction drives, before 75 imbalances of magnet rotary body, ratchet mechanism 79 plays a role, and can cut off being connected of stepper motor 7 and toilet seat assembly 10.Therefore, positive direction imbalance moment of torsion can make the intensity of driving mechanism 5 descend with the difference of following direction idling torque, so can make the component thin typeization, realizes the miniaturization of driving mechanism.
(other examples)
Under the situation of above-mentioned example, the following direction idling torque of ratchet mechanism 79 is littler than forward imbalance moment of torsion, but also can make the following direction idling torque of ratchet mechanism 79 bigger than forward imbalance moment of torsion.This occasion, till 75 imbalances of magnet rotary body, claw 74d is maintained with engaging of the 75f of wall portion.Therefore, after magnet rotary body 75 imbalance, rotate at a high speed, but for the inertia force of magnet rotary body 75, cut off being connected of stepper motor 7 and toilet seat assembly 10 by ratchet mechanism 79, so can prevent the breakage of driving mechanism 5 towards the W direction.
In addition, the ratchet mechanism 79 of above-mentioned example constitutes, cut off because of to toilet seat assembly 10 towards the decline directive effect and make the overload of stepper motor 7 imbalances cause the inertia force of 7 pairs of toilet seat assemblies of stepper motor, 10 transmission that imbalance is rotated, but also can constitute on the contrary, cut off because of to toilet seat assembly 10 towards the rising directive effect and make stepper motor 7 that the overload of stepper motor 7 imbalances causes that imbalance rotates inertia force to 10 transmission of toilet seat assembly.
At this moment, as above-mentioned example, the overload, pinion rotary body 74 that descent direction is arranged when toilet seat assembly 10 effect be during towards the structure of W direction rotation, as long as with Fig. 4 (a) arm of ratchet 74c is shaped to the V direction is outstanding.After constituting like this, toilet seat assembly 10 in decline direction driving process, has been acted under the situation that makes the excessive power that toilet seat 12 floats in mistake, after imbalance, rotated at a high speed to the V direction towards W direction rotor rotated 76.Along with stopping of toilet seat assembly 10, pinion rotary body 74 stops, claw 74d and the 75f of wall portion butt, and the inertia force of effect magnet rotary body 75, then arm of ratchet 74c deflection to the inside, claw 74d crosses the 75f of wall portion, allows the rotation of rotor 76.Therefore, when toilet seat assembly 10 stops, not having big overload and act on driving mechanisms 5 such as reduction gearing row 70, slide block 51, can prevent breakage.
And, in the above-mentioned example, used ratchet mechanism 79, but be not limited to ratchet mechanism 79 as torque limiter.That is, also can constitute at the bidirectional clutch shown in Figure 6 79 ' that both direction equates by idling torque.In the bidirectional clutch 79 ' of this form, put on identical symbol, omit the explanation of common ground having with the position of ratchet mechanism 79 identical functions of above-mentioned example.
The pinion rotary body 74 of the rotor 76 shown in this form, upside at the outer wall of the 74b of tube portion forms pinion 74a, simultaneously, shown in Fig. 6 (a), form the tie-beam 74e that are connected with the annulus 74c ' that surrounds this outer wall at 2 positions of the circumferencial direction of downside.On 2 positions on the outer wall of this annulus 74c ', circumferencial direction, the claw 74d ' that the outstanding concavo-convex 75c ' of tooth portion that forms with the inwall of the 75b of urceolus portion that is formed at magnet rotary body 75 fastens.And metal C ring 83 is by external force and chimeric with the inwall of annulus 74c ' under the state of diameter reduction.Therefore, C ring 83 is thought enlarged, and the state with the application of force makes claw 74d ' and the 75e ' of tooth portion butt all the time.The idling torque of the bidirectional clutch 79 ' of this form is set between reverse imbalance moment of torsion and the forward imbalance moment of torsion.
And, in the above-mentioned example, do not relate to the frequency of the driving pulse of stepper motor 7, but can suitably set.For example, also can be than the frequency of the driving pulse of toilet seat assembly 10 when the rising direction drives is big with the frequency setting of the driving pulse of toilet seat assembly 10 when the decline direction drives.So constitute, when effect has when making toilet seat assembly 10 towards the overload of decline direction, can make forward imbalance moment of torsion decline the rotor 76 of toilet seat assembly 10 when the decline direction drives.Therefore, moment of torsion becomes and the size of the moment of torsion equal extent of oppositely lacking of proper care forward to be lacked of proper care.Therefore, can make the intensity decline of driving mechanism be equivalent to the amount that forward imbalance moment of torsion reduces,, realize the miniaturization of driving mechanism so can make component thin typeization etc.
