The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is elaborated.
Accompanying drawing 1-3 illustrates the utility model first embodiment.Like Fig. 1, shown in 2 and 6, the seat inclining rotary mechanism comprises base 10 and is fixed on half basin mechanism 100 on the base 10.Half basin mechanism comprises half basin 110 and the half basin supporting bracket 120 that is fixed on these half basin, 110 belows; This half basin 110 is articulated on the half basin mechanism turning cylinder 140 through half basin fixed support 130; This half basin supporting bracket 120 also is articulated on this half basin mechanism turning cylinder 140, and this half basin mechanism can wholely rotate around this half basin mechanism turning cylinder 140 like this.As shown in Figure 1, be provided with the first locking engaging tooth 124 at the pivot end 122 of a side of this half basin supporting bracket 120.
This seat inclining rotary mechanism also comprises lever lock locking mechanism 200, itself and this be provided with pivot end 122 homonymies of the first locking engaging tooth 124.This lever lock locking mechanism 200 comprises locking lever 210, and it is connected on the base 10 through lockable mechanism turning cylinder 220.Locking lever 210 1 ends are provided with release lever 212, the other end be provided with can with this first locking engaging tooth, 124 ingears, second locking engaging tooth 214 (as shown in Figure 3).On this lockable mechanism turning cylinder 220, be provided with locking pull back spring 222.
Below this half basin supporting bracket 120, be provided with half basin lift system 300; It is a torsion spring mechanism in the present embodiment; Wherein torsion spring rotating shaft 310 is fixed on the base 10, and torsion spring 320 1 ends are fixed on this half basin supporting bracket 120, and the other end is fixed on the base 10.This seat inclining rotary mechanism can comprise that two and half basin lift systems 300 are located at the both sides of this half basin supporting bracket 120 respectively.
With reference to accompanying drawing 3-5, when in the power that applies on the handle 212 upwards (shown in Fig. 3 arrow), lever 210 rotates, and makes the ingear first locking engaging tooth 124 and the second locking engaging tooth 214 throw off.
At this moment, 320 pairs of these half basin supporting brackets of torsion spring 120 produce thrust upwards, make it have the trend (shown in Fig. 4 arrow) of upwards rotating around this half basin mechanism turning cylinder 140 jointly with this half basin 110.And the passenger can apply (or utilizing body weight to produce) downward power, and this power is delivered on half basin 110, makes it have the trend that rotates around this half basin mechanism turning cylinder 140 jointly with this half basin supporting bracket 120.The mutual action of these two power can forward this half basin mechanism 100 to the angle of needs.
At this moment, discharge the power that is applied to this handle, lever 210 gets back to making this first locking engaging tooth 124 and the second locking engaging tooth, 214 position engaged under the effect of locking pull back spring 222.
In the foregoing description, the shape of this locking lever 210 is configured to: when this first locking engaging tooth 124 meshed with this second locking engaging tooth 214, the direction of the interaction force that their flank of tooth produces was through the turning cylinder 220 of this lever 210.This be because; If this application force is through this lockable mechanism turning cylinder 220, this power will not produce the moment around this turning cylinder 220, and then makes lever 210 trend that rotates; If the direction of moment is with shown in Figure 5 in the opposite direction, then can cause locking structure to be thrown off.In the present embodiment, the end that this second locking engaging tooth 214 is set is configured to curved shape, thereby makes the normal of the flank of tooth of two locking engaging tooths through this lockable mechanism turning cylinder 220.
In addition, in first embodiment, an end of torsion spring 320 directly is fixed on this supporting bracket 120.Therefore, torsion spring 320 is stressed for a long time, and it is bigger to receive tensile force, can cause fracture.
To above-mentioned situation, the utility model has also proposed another solution.Fig. 7-17 illustrates second embodiment of the utility model.Second embodiment is that with the first embodiment difference structure of this lockable mechanism and this half basin lift system is different, and the structure of remainder is identical with first embodiment.In accompanying drawing 7-17, similar parts use similar Reference numeral to represent.
As shown in the figure, lockable mechanism 200 ' comprise lockable mechanism support 250, lockable mechanism turning cylinder 220 ' be located on this lockable mechanism support 250.Locking lever 210 ' be arranged to center on this turning cylinder 220 ' rotation.Equally, this locking lever 210 ' one section be provided with release lever 212 (as shown in Figure 7), the other end be provided with can with this first locking engaging tooth, 124 ingears, second locking engaging tooth 214 '.This lockable mechanism turning cylinder 220 ' on be provided with locking pull back spring 222 '.
In the present embodiment; This locking lever 210 ' be configured to this engaging tooth 124 and 214 ' extend axially; Like this its direction of this turning cylinder 220 ' be arranged to and this engaging tooth 124 and 214 ' the application force that produces of active flank consistent, for example be parallel to this force direction.
In addition, in the present embodiment, this torsion spring mechanism 300 ' in also comprise the slide block 350 that is located on this half basin supporting bracket 120.Among first embodiment, torsion spring 320 is fixed on fixing this slide block 350 of that end on this support 120.This torsion spring mechanism 300 ' all the other the structure with first embodiment in torsion spring mechanism 300 identical.
Like Fig. 8-10, when handle 212 being applied the power that makes progress, this first locking engaging tooth 124 and this second locking engaging tooth 214 ' disengagement.Similar with first embodiment, under the power effect that torsion spring 320 and passenger apply, can this half basin mechanism 100 be forwarded to the angle of needs.Discharge the power be applied to this handle 212 then, locking pull back spring 222 ' effect under, this first locking engaging tooth 124 and this second locking engaging tooth, 214 ' again engagements.
In the present embodiment because this locking lever 210 ' be configured to this engaging tooth 124 and 214 ' extend axially, like this this engaging tooth 124 and 214 of this turning cylinder 220 ' be arranged to be parallel to '.So, under engagement, the application force that this first locking engaging tooth 124 and this second locking engaging tooth, 214 ' flank of tooth produce be parallel to this turning cylinder 220 '.Like this application force that produces of the flank of tooth can not produce around this turning cylinder 220 ' moment.
In addition; This slide block 350 is sliding on this half basin supporting bracket 120 under the effect of torsion spring 320, thereby when this half basin mechanism 100 is locked at certain angle, because this slide block 350 can slide; Can significantly reduce the stretching action that this torsion spring 320 receives, improve the life-span of torsion spring.
Figure 13-17 is three-dimensional view and partial schematic diagrams of other angles of inclining rotary mechanism of second embodiment.Other structures of second embodiment are identical with first embodiment.
Although the utility model is described according to its preferred implementation, there are the change, displacement and the various substitute equivalents that fall in the utility model scope.Here the example that provides only is illustrative, rather than to the restriction of the utility model.
For the sake of simplicity, this specification sheets has omitted the description to known technology.
