When the movable pedal component is stored under the seat, the limit pin of the pedal always pushes against the rear part of the groove through the pulling force action of the reset elastic piece, and the horizontal state of the pedal is kept.
Workflow or working principle of example 1: as shown in fig. 4 to 6, the footrest is mounted on the bottom surface of the seat cushion 1, and in an initial state, the movable footrest assembly is retracted in the seat bottom space. When the pedal is needed, the driving assembly 2 drives the sliding block 301 to drive the movable pedal assembly to move outwards along the horizontal sliding rail 3, and when the pedal rotating member 104 contacts the round wheel 402, the movable pedal assembly is in an extending state. The driving assembly 2 continues to push the movable pedal assembly 1, so that the pedal rotating part 104 is subjected to the reaction force of the circular wheel 402, because the connecting point of the pedal rotating part 104 and the rotating fixing plate 103 is positioned below the circular wheel 402, the pedal rotating part 103 can be tightly attached to the circular wheel 402 to do upward swinging motion and be tightly attached to the circular wheel 402 under the action of the reset elastic part 106, meanwhile, due to the pulling of the pedal connecting part 105, the pedal 101 extends out of the front part of the seat, meanwhile, the pedal 101 rotates and is lifted upwards, so that the pedal inclines towards the direction far away from the seat, and the feet are conveniently placed for a user.
When the movable pedal assembly 1 is reset, the driving assembly 2 drives the movable pedal assembly 1 to return to the initial position.
The beneficial effects of this embodiment: the utility model discloses it is underneath with pedal device erection connection to seat, drive movable pedal assembly through the driver and make horizontal concertina movement for the whole occupation space of pedal device is less, can make the space maximize of seat below. And the whole thickness of the seat can be very thin, so that the whole seat looks more integrated, and the requirement of conciseness and beauty advocated by the current society is met.
