The electric telescopic structure in the massage chair is not described in detail, and please refer to the electric telescopic technology of the existing massage chair for details.
Further, the ground contacting part comprises a roller 34 and a ground contacting bracket 33 for supporting the roller 34, one end of the torsion spring 32 is connected to the ground contacting inductive switch 31, the other end is connected to the left end of the ground contacting bracket 33, and the roller 34 is connected to the right end of the ground contacting bracket 33. Specifically, the roller 34 contacts the ground, so that the ground bracket 33 drives the torsion spring 32 to trigger the ground contact inductive switch 31, thereby controlling the motion state of the electric telescopic lower leg mechanism 1. Further making the detection effect and safety protection effect of the ground contact protection device 3 more efficient.
Further, the electric leg stretching mechanism comprises a driving mechanism 4, a pedal leg stretching mechanism 5 arranged below the electric leg stretching mechanism 1, a foot moving frame 6 used for fixedly supporting the pedal leg stretching mechanism 5, and a walking screw 7 used for enabling the pedal leg stretching mechanism 5 to stretch towards the electric leg stretching mechanism 1. Specifically, the driving mechanism 4 drives the foot movable frame 6 to rotate by a thread through the walking screw, thereby driving the pedal lower leg stretching mechanism 5 to stretch in the direction of the electric lower leg stretching mechanism 1.

Specifically, the walking motor drives the foot movable frame 6 to perform a screw rotation and generate a displacement through the walking screw, and simultaneously, the pulley 61 slides in the sliding groove 21, so that the foot movable frame 6 pulls the pedal lower leg stretching mechanism 5 to stretch in the direction of the electric lower leg stretching mechanism 1 along the sliding groove 21. When in use, the heel of a user contacts with a sole induction unit arranged on the pedal telescopic shank mechanism 5, a walking motor drives the foot movable frame 6 to rotate in a thread way through the walking screw rod and generate displacement, so that the foot movable frame 6 makes linear motion downwards along the sliding groove 21 through the pulley 61, if the electric telescopic shank mechanism 1 swings towards the ground at the moment, the roller 34 elastically contacts the ground first, meanwhile, the ground contact bracket 33 is driven to trigger the ground contact induction switch 31, a ground contact signal is transmitted into a signal channel of the ground contact induction switch 31, finally, the ground contact induction switch 31 controls the electric telescopic shank mechanism 1 to stop descending or lift upwards so as to avoid continuous ground contact, and if the electric telescopic shank mechanism is lifted upwards, the roller 34 is returned to the initial state by the returning torsion force of the torsion spring 32.
In a further scheme, the ground contact protection device 3 further includes a ground contact base 35 and a pin shaft 36, the ground contact sensing switch 31 is fixed at the upper end of the ground contact base 35, the ground contact support 33 is hinged to the lower end of the ground contact base 35 through the pin shaft 36, the torsion spring 32 is connected to the pin shaft 36 in a penetrating manner, one end of the torsion spring is connected to the ground contact piece, and the other end of the torsion spring 32 abuts against the ground contact base 35; the roller 34 contacts the ground to drive the torsion spring 32 to generate a reset torsion and act on the ground contact base 35, and the ground contact base 35 transmits a ground contact signal to the ground contact inductive switch 31.
