The technical scheme of the invention is further described in detail by the following specific embodiments in combination with the attached drawings:

example 1

As shown in fig. 1, a seat pedal device comprises a movable pedal assembly 1, a driving assembly 2 for driving the movable pedal assembly 1 to move, and a frame assembly 4 provided with a horizontal slide rail 3, wherein the driving assembly 2 is installed at one end of the frame assembly 4, the movable pedal assembly 1 is installed on the horizontal slide rail 3, and the driving assembly 2 drives the movable pedal assembly 1 to move on the horizontal slide rail 3; the movable pedal assembly 1 comprises a pedal 101 far away from the driving assembly 2 and a connecting mechanism for driving the pedal 101 to swing, and a swing driving mechanism for driving the connecting mechanism to swing is arranged on one side of the frame assembly 4 far away from the driving assembly 2. In order to mount the footrest on the seat cushion, the frame assembly 4 is provided with a rear plate 403 and a rear mount 404 on a side close to the drive assembly 2 and a front mount 405 on a side remote from the drive assembly 2; the back plate 403 and the back fixing 404 are L-shaped. The rear plate, the rear fixing member and the front fixing member are used to mount the footrest on the seat cushion.

Specifically, the driving assembly 2 is a motor driving assembly, a sliding block 301 connected with the motor driving assembly is arranged on the horizontal sliding rail 3, and the sliding block 301 is connected with the movable pedal assembly 1. The movable pedal assembly is driven by the motor to move without being driven by hands, so that the pedal device is more convenient and practical.

Specifically, as shown in fig. 2, the connecting mechanism includes a transverse connecting plate 102, a rotation fixing plate 103 installed at both sides of the transverse connecting plate 102, and a pedal rotation member 104 and a pedal connecting member 105 respectively installed at both side surfaces of the rotation fixing plate 103, and both ends of the pedal rotation member 104 and the pedal connecting member 105 far from the rotation fixing plate 103 are rotatably connected to the pedals 101. One end of the pedal rotation member 104 near the rotation fixing plate 103 is connected to the rotation fixing plate 103 through a return elastic member 106. The pedal assembly moves out of the seat and is in contact with the swing driving mechanism, the swing driving mechanism drives one ends of the pedal rotating pieces on two sides to swing upwards to form a certain angle, and meanwhile the pedal connecting pieces can pull the pedals to rotate upwards, so that the pedals are kept horizontal.

In addition, the pedal rotation member 104 and the rotation connecting member 105 on both sides are of an integrated structure and are fixedly connected through a connecting rod. The unitary construction allows for more consistent motion.

Further, as shown in fig. 3, the swing driving mechanism includes a mounting frame 401, a circular wheel 402 mounted on the mounting frame 401 through a circular shaft, and the vertical position of the circular wheel 402 is higher than the position of the connection point of the pedal rotation member 104 and the rotation fixing plate 103; the movable footrest assembly 1 is moved to the other end of the frame assembly 4 and the round wheel 402 abuts the footrest rotation member 104.

The pedal rotation member 104 and the circular wheel 402 are liable to be out of continuous contact during the pedal retraction process, which may cause the pedal to drop suddenly. And spacing portion 1041's top and round wheel 402 butt, pedal rotation piece 104 also with round wheel 402 butt, both are equivalent to press from both sides round wheel 402, when pedal withdrawing, because the vertical position of round wheel 402 is higher than the position of the pedal rotation piece 104 with the tie point of rotating fixed plate 103, and under the effect of elastic component 106 that resets, round wheel 402 can be hugged closely to spacing portion 1041, make pedal rotation piece 104 and round wheel 402 be in the contact state always, the problem of stepping down has been avoided, stability is improved. Meanwhile, the pedal rotating piece 104 and the round wheel 402 are always in a contact state, so that the pedal rotating piece 104 can be kept stable when external force is applied, the relative position between the pedal rotating piece 104 and the pedal 101 cannot be changed, the pedal rotating piece cannot turn backwards, and the anti-clamping effect is achieved.

Further, as shown in fig. 4, one end of the pedal rotation member 104 near the pedal 101 is provided with a groove 108, and the pedal 101 is provided with a stopper pin 107 to be inserted into the groove 108. 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 Figs. 4-6, the footrest apparatus is mounted on the bottom surface of the seat cushion 1, and in an initial state, the movable footrest assembly is retracted into 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 rotating 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 pedal device is arranged and connected under the seat, and the movable pedal component is driven by the driver to horizontally extend and retract, so that the whole occupied space of the pedal device is smaller, and the space under the seat can be maximized. 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.
