When sitting, the sitting and lying seat is locked by the electric push rod component. When the piece of seating and reclining furniture is to be gradually switched from the seating position to the reclining position, the following continuous movement is generated due to the moving characteristics of the parallelogram frame. The person sits on the seat, the control button II is operated, the electric power of the electric push rod enables the seat back to gradually tilt backwards, the seat is horizontally moved towards the rear lower side, and the height is gradually reduced. Meanwhile, the supporting point of the original auxiliary supporting piece of the sitting and lying seat can synchronously move backwards along with the backward movement of the gravity center of the human body, thereby ensuring the stable switching and eliminating the trouble of backward turning when the sitting and lying seat is lying. When the seat needs to be locked at a certain position, the control button II is operated, the locking force of the electric push rod locks the seat for sitting and lying at the position, and the seat for sitting and lying is semi-reclined or the height of the seat for sitting and lying is adjusted. Therefore, when the sitting position is gradually switched to the lying position, the adjustment is stepless within a certain stroke; when the user wants to switch from the lying position to the sitting position step by step, the user still sits on the sitting and lying seat, the control button II is operated, the electric power of the electric push rod enables the back of the seat to swing forwards and upwards step by step, the seat of the seat moves forwards and upwards in a translation mode, the height is increased step by step, meanwhile, the supporting point of the original auxiliary supporting piece of the sitting and lying seat moves forwards synchronously along with the forward movement of the gravity center of the human body until the sitting and lying seat is restored to the sitting position step by step. And the control button II is operated, and the electric push rod locks the sitting and lying seat in the sitting position. When the sitting position is switched to the lying position, or the lying position is switched to the sitting position, the power is derived from the electric power. Therefore, the stepless adjustment of the person sitting and lying on the sitting and lying piece of seating and lying furniture within a certain stroke is bidirectional. When lying statically, the feet are placed on the ground, so that the large, the small and the legs and the feet of a person can be placed comfortably, thereby being beneficial to the running of meridians and collaterals and qi and blood and being beneficial to health.
2) Dynamic use of motion.
Due to the kinematic properties of the parallelogram frame, the following continuous motion is generated. The control button II is operated to enable the electric push rod to realize continuous circular operation, so that the sitting and lying seat is continuously switched from the sitting position to the lying position and from the lying position to the sitting position; the supporting points of the original auxiliary supporting piece assembly for sitting and lying move along with the front and back circulating movement of the gravity center of the human body, and the synchronous front and back circulating movement ensures the dynamic use safety. In the continuous circulation switching, the person sitting and lying on the seat can obtain whole body passive movement including the flexion and extension movement of almost all joints and the like through the back and forth up and down translation of the seat, the flexion and extension of the armrests and the swinging of the back of the seat, so that the whole body channels, qi and blood are moved, and the body is strengthened and maintained. If the music is matched, the body building and health preserving effects are better. The dynamic use of the sitting and lying seat is also suitable for the general relaxation of people after tense exercise, in particular to athletes.
To sum up, the utility model perfectly combines the motion characteristics of the parallelogram main body mechanism of the telescopic office and study chair with patent number ZL201721517914.0 and the parallelogram main body mechanism of the telescopic chair with patent number ZL201820336205.0, and is an improvement and lifting of the locking device/switching mechanism of the two technical schemes, thereby greatly improving the quality and quantity of the chair with sitting and lying, leading the chair with ① to be convenient, reliable and stepless to switch and have a higher grade, ② to realize the operation of sitting and lying on the chair with people, ③ can realize the static use of sitting and lying and the dynamic use of movement, when the chair is used statically, because the feet are placed on the ground, the big shank and the feet of people can be unfolded, thus being beneficial to the operation of channels, collaterals and qi and blood, being beneficial to health, when the chair is used dynamically, the chair is translated back and forth through the chair seat, the armrests are bent and stretched, and the back swing, the whole body joints are fully stretched, the whole body movement is achieved, the whole body-building and the blood-building instrument is suitable for the dynamic use of athletes, and the blood-building and the whole body-building instrument is more suitable for the health-keeping and blood-keeping effect.
