Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, sectional type massage chair backrest, its structure longitudinally divides three sections of designs according to human necks, shoulders portion, back, lumbar shape, be respectively neck shoulder section 1, back section 2 and waist section 3, flexible adjustable link is provided with between each section point, through the being converted by folding of different amplitude, the overall scale of construction of massage armchair is reduced.Neck shoulder section 1 part is held concurrently when user headrest, and both sides are slightly protruding, filling sponge; Slightly cave in centre, massage head is close to precoat, and overall is " recessed " type structure; Neck shoulder section 1 part adopts a pair fixed massage head of single head, and its periodic rotary produces the massage effect of kneading, finger pressure.Back section 2 scale of construction is comparatively large, and smooth by face, both sides filling sponge, slightly caves in body contacting portion; Back section 2 part adopts rolling wheel massaging head, can, by also moving up and down along screw mandrel, realize massaging continuously.The similar back portion of waist section 3 moulding, the scale of construction is slightly little, highly shortens; Contact surface entirety S-type curve on side view.The fixed massage head of waist section 3 part Bian double end, its cycle rotates the massage effect producing kneading, roll extrusion.Neck shoulder section 1, back section 2 and waist section 3 structurally include the parts such as shell (can be plastic material), support (being mainly used in supporting massage mechanism), implant (such as sponge), and shell is wrapped up by precoat, and backrest back side part is exposed.
As shown in Figure 2, Figure 3, Figure 4, neck shoulder section 1 comprises the first shell 16, first support 21 and acts on two single head formula cylindrical massage 7 of neck and shoulder part both sides respectively, first support 21 is established the first motor 6, two single head formula cylindrical massage that it is installed 7 are driven after the axial trough of the first motor 6 and two gears meshing, single head formula cylindrical massage 7 acts on neck and shoulder part both sides respectively, and its periodic circumference rotates the massage effect producing kneading, finger pressure.Back section 2 comprises the pulley massage mechanism of second housing 19, support and two pairs of pulley type massage head compositions; Support is the square set be made up of two cross bars 10 and two montants 11; Pulley massage mechanism comprises movable motor 8, pulley massage head 9, stroke lever 12 and screw mandrel 13; Stroke lever 12 has two, is parallelly located on square set; Screw mandrel 13 is vertically located on stroke lever 12, and one end is connected with cross bar 10; Movable motor 8 is connected with screw mandrel 13, pulley massage head 9 is connected with movable motor 8, the massage carrying out various ways is driven by movable motor 8, can slide along screw mandrel about 13 by the track preset, realize continuously massage and fixed point vibration massage function etc., massage, roll extrusion, the massage effect that knocks are produced to back.Waist section 3 comprises the 3rd shell 20, the 3rd support 17 and acts on the bullhead carousel-type massage head 15 of lumbar vertebra both sides, 3rd support 17 is established the second motor 14, drive the bullhead carousel-type massage head 15 that it is installed after the axial trough of the second motor 14 and two gears meshing, bullhead carousel-type massage head 15 periodically rotates massage effect lumbar vertebra both sides being produced to kneading, roll extrusion.Between neck shoulder section and back section, between back section and waist section, be all connected 4 two kinds of modes by outside connection 5 with inside and connect simultaneously, the mutual coordinating and unifying of connected mode at inside and outside two places, ensure the flexible adjustable of back-rest means for chair.
As shown in Figure 4 and Figure 5, the U-type groove 22(that outside connection 5 embeds next part housing top end for the gear 18 being located at last point of shell bottom is inverted U-shaped), the gear teeth of gear engage with the tooth-like projection 24 on U-type groove 22 inwall, and the rotation of gear 18 and location realize rotation among a small circle and the stretching of related device outside.Be specially: bottom the first shell 16, establish a gear 18, establish a U-type groove 22 on second housing 19 top, be located at the tooth-like projection 24 of U-type groove 22 inside and the gear teeth meshing of gear 18.Bottom second housing 19, establish a gear 18, establish a U-type groove 22 on the 3rd shell 20 top, be located at the tooth-like projection 24 of U-type groove 22 inside and the gear teeth meshing of gear 18.Tooth-like projection 24 is located on linkage board 26, and linkage board 26 is actively installed in U-type groove 22, establishes the first spring 25, be provided with inclined-plane in one end of linkage board 26 between U-type groove 22 and linkage board 26; U-type groove 22 is provided with a fixing head, between this fixing head and button 28, is provided with the second spring 29, the side of button 28 is provided with wedge surface 27 and is used in combination with the inclined-plane of linkage board 26.During work, press the button 28, wedge surface 27 compresses the first spring 25 by the inclined-plane compressing linkage board 26 of linkage board 26, makes tooth-like projection 24 outwards indentation, leaves meshed gears 18; Now gear 18 can do the adjustment that certain angle rotates and moves up and down in U-type groove 22, and after completing, release button 28, linkage board 26 playbacks, and tooth-like projection 24 and gear 18 engage each other, fixing.
Inner connection 4 is connecting rod connection, and connecting rod two ends are spherical, and embed respectively and be connected in the corresponding link slot of two-part support, the rotation of connecting rod and pull realize rotation and the slippage of inner frame.Be specially: on the first support 21, be provided with calabash shaped link slot, (on) cross bar 10 is provided with link slot, the spherical termination of connecting rod is provided with multiple screens, two ends be connected respectively calabash shaped link slot and (on) in the link slot of cross bar 10.3rd support 17 is provided with calabash shaped link slot, (under) cross bar 10 is provided with link slot, the spherical termination of connecting rod is provided with multiple screens, two ends be connected respectively calabash shaped link slot and (under) in the link slot of cross bar 10.
Sectional type massage chair backrest of the present invention, backrest neck and shoulder part divides holds concurrently when user headrest, " recessed " type structure slightly caved in the middle of employing both sides are slightly protruding; Back portion is smooth by face, slightly caves in; The similar back portion of waist section moulding, the scale of construction is slightly little, highly shortens; Contact surface entirety S-type curve on left view, in the hope of meeting human vertebra structure better.Inside is provided with different massage appliances, meets the massage demand of different parts.The collapsible conversion of back-rest means for chair, makes the overall scale of construction of massage armchair reduce, more saves the interior space.The shoulder cervical region of backrest, back, waist three part realize independent control, and size and angle can regulate respectively, at utmost meet the demand of all ages and classes stage body dimension and form; Global design is pursued from " making people adapt to seat " to the transformation of " making seat be applicable to people ".
