the driving device comprises a linear motor and a sliding block arranged on an output shaft of the linear motor, the linear motor is hinged to the base, the sliding block is hinged to the bottom of the backrest frame, and the backrest frame is driven by the driving device to move and turn under the guidance of a guide rail on the base.
On the basis of the technical scheme, the utility model discloses can also do following improvement.
Preferably, the straight rail is inclined to the rear and upward direction, and the included angle formed by the straight rail and the horizontal plane is between 20 degrees and 50 degrees.
Preferably, the circular arc curved track has a central angle of 25 ° to 70 °.
Preferably, the second roller is disposed at a position higher than that of the first roller.
Preferably, the backrest frame comprises two parts, a backrest part and a seat frame part.
Compared with the prior art, the utility model discloses following technological effect has:
because the arc-shaped guide rail and the straight-line guide rail are tangentially connected, the guide rail is processed and molded at one time, and the process is simpler; when the chair is adjusted from the sitting posture to the lying posture, the backrest frame does not need to rotate backwards, but the whole backrest frame moves forwards and upwards along the composite curve track, so that the chair can be completely placed against the wall, the space for turning back the backrest is not required to be reserved, and the space occupied by the massage chair when in use is reduced.
The straight-line section track is arranged in a mode of inclining towards the rear upper side, so that the guide rail is integrally in a state of being high at two ends and low in the middle, the backrest frame can be turned over at a large angle, meanwhile, when the backrest frame moves forwards and turns over, the height of the seat part correspondingly descends, the height of the whole machine behind the backrest is reduced, the height of a packing box is reduced, and the cabinet loading amount is increased.
Therefore, the utility model discloses a massage armchair turns over back of body structure, chair frame main part assembly module only seat back of the body frame, base and drive arrangement triplex, and the assembly is simple, and assembly efficiency is high.
