Further preferably, described underframe a is located on a rotating mechanism, and described rotating mechanism is fixed on a chassis 8.
The method of work of above-mentioned multi link extension means, is characterized in that comprising:
When this multi link extension means is in contraction state, namely sofa is in sitting posture state, open motor k3 to rotate with drive screw, under the mating reaction of screw rod and slide block k6, on, lower dwang s, the j corresponding torsion of upper production and spacing increase gradually, the torsion that lower dwang j produces is through rebound i, first driver plate z1 and the second driver plate z2 is passed on first connecting rod r1, due to first on installing plate h, second limited post t1, t2 acts in corresponding spacing breach u respectively, and the first driver plate z1 is in contraction first with the point that is flexibly connected of first connecting rod r1, second limited post t1, between t2, therefore first connecting rod r1 temporarily cannot action, now only described upper dwang s rotates and forward upward displacement,
Described upper dwang s drives described sole support v, toe board w forward upward to stretch, simultaneously from front end lifting installing plate h;
When the stretching of described sole support v, toe board w completes, motor k3 drives the spacing rotating up and down bar s, j to continue to increase, first, second limited post t1, t2 depart from corresponding spacing breach u respectively, and then make first connecting rod r1 increase, topple over backward to drive described back rest m, until arrive the extreme angles preset, namely this multi link extension means arrives the state of full extension, and namely sofa is in the state of couching.
When back rest m starts to topple over backward, the pilot pin d1 on described swing sheet d starts to embed in the U-lag of described spacer x, namely forms locking, to prevent in back rest m toppling process and sofa rocks before and after occurring after having toppled over.
As Fig. 5, when described multi link extension means is in contraction state, namely sofa is in sitting posture state, the spacing of lower dwang j, upper dwang s is in minimum state, because slide block k6 is hinged on the hinged seat of lower dwang j by contiguous block k5, the top of motor cabinet k2 is hinged on the hinged seat of dwang s, open motor k3 to rotate with drive screw, under the mating reaction of screw rod and slide block k6, lower dwang j, when the spacing of upper dwang s increases gradually, on, lower dwang produces corresponding torsion respectively, the torsion that lower dwang j produces is through rebound i, first driver plate z1 and the second driver plate z2 is passed on first connecting rod r1, the first limited post t1 on installing plate h, second limited post t2 acts on the upper of the two ends of contiguous first connecting rod r1 respectively, in the spacing breach u of lower edge, because the first driver plate z1 is in contraction first limited post t1 with the point that is flexibly connected of first connecting rod r1, between second limited post t2, therefore the position-limiting action of a pair spacing breach u, make first connecting rod r1 temporarily cannot action, therefore, now only described upper dwang s rotates and forward upward displacement, described upper dwang s drives described sole support v, toe board w forward upward to stretch, simultaneously from front end lifting installing plate h, when the stretching of described sole support v, toe board w completes, motor k3 drives lower dwang j, the spacing of upper dwang s continues to increase, first limited post t1, the second limited post t2 depart from corresponding spacing breach u respectively, and then make first connecting rod r1 increase, topple over backward to drive described back rest m, until arrive the extreme angles preset, namely whole multi link extension means arrives the state of full extension, as Fig. 7-9.Now, pilot pin d1 on described swing sheet d embeds in the U-lag of described spacer x, namely forms locking, has three stress points to prevent from rocking before and after sofa generation on swing sheet d now, therefore sofa swings sheet d cannot freely swing, so can not rock front and back.
As Fig. 1 to 4, described rotating mechanism comprises: upper shell 1, lower house 2, is located at the multiple balls between upper and lower casing, for the ball retainer 3 of spacing each ball, to be located between upper and lower casing and to be in the brush assembly of electric 4 of ball retainer 3 central authorities.
Brush assembly of electric 4 comprises: upper annular solid 41, lower annular solid 42, the adjacent face of upper and lower annular solid is distributed with at least one pair of laterally zygomorphic cannelure 43, be distributed with multiple conductive contact in a pair cannelure on the lower surface of upper annular solid 41, and the conductive contact in same cannelure is connected with single power line 7; The conductive ring that the preferred copper band of endless metal circle that is connected with a pair circumscripted power line 6 respectively or graphite material are made is provided with in a pair cannelure of the upper surface of lower annular solid 42.
Conductive contact in same cannelure is the elastic sheet metal preferred elastomeric copper sheet being suitable for contacting with the endless metal circle below it, and is uniformly distributed.
Described ball retainer 3 is coaxially arranged with brush assembly of electric 4, and upper and lower casing is fixed by central bolt about 5.
Brush assembly of electric is adopted to realize being rotatably assorted of power supply, make the conductive contact in pressed on ring a pair cannelure physically, coordinate with the activity of the endless metal circle in a pair cannelure on lower annular solid respectively, power supply is made to remain on-state, and then realize avoiding power cable to be wound around under the continuous 360 ° of rotational case of sofa, convenient for users, and improve comfort level and the reliability of product use.
Obviously, above-described embodiment is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to spirit institute's apparent change of extending out of the present invention or change and are still among protection scope of the present invention.
