Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

Fig. 1 shows a pedal rotation limiting structure, which comprises a seat frame 1, a leg rest assembly 2 and a pedal frame 3. The front end of the seat framework 1 is rotatably connected with the leg support assembly 2, and the front end of the leg support assembly 2 is rotatably connected with the pedal framework 3 through a rotating mechanism. The rotating mechanism adopted in the embodiment is specifically an angle adjuster 4, the rear end of the pedal framework 3 is connected to the front end of the leg support component 2 through the angle adjuster 4, and the rotating angle of the pedal framework 3 can be conveniently adjusted through the angle adjuster 4.

In order to avoid the excessive rotation of the pedal framework 3 from interfering with the leg support assembly 2 or other parts in the vehicle, a limiting mechanism is arranged between the pedal framework 3 and the leg support assembly 2. Specifically, as can be seen in fig. 2, the limiting mechanism includes a limiting plate 5, a front stopper 6a, and a rear stopper 6b. The front stop block 6a and the rear stop block 6b are arranged at the front and the rear rotation limit positions of the pedal framework 3, the limiting plate 5 is fixedly connected to the leg support assembly 2, and the three parts are distributed around the rotation center line of the pedal framework 3 and are positioned on the same circular ring. One section arc region between positive stop 6a and the backstop 6b forms spacing breach 6, is provided with in this spacing breach 6 limiting plate 5, works as when pedal skeleton 3 rotates extreme position, positive stop 6a or backstop 6b butt are in with stall on the limiting plate 5.

As can be seen from fig. 1, the pedal frame 3 includes two side plates 31 disposed opposite to each other on the left and right, a cross bar 32 is connected between the front ends of the two side plates 31, and the rear ends of the two side plates 31 are rotatably connected to the leg rest assembly 2 through the angle adjuster 4. The front stop block 6a and the rear stop block 6b are arranged at the rear end of each sideboard 31, and the limiting plates 5 are correspondingly arranged at two sides of the front end of the leg support assembly 2 respectively.

As can be seen in fig. 2, two side plates 31 are respectively located at two sides of the leg rest assembly 2. The limiting plate 5 comprises a connecting part 51 and a stopping part 52, the connecting part 51 is flat, the connecting part 51 is located between the leg support assembly 2 and the side plate 31 on the same side, and the connecting part 51 is fixedly attached to the leg support assembly 2. The stop portion 52 is perpendicular to the connecting portion 51, the stop portion 52 extends laterally outward, and the stop portion 52 is located above the side plate 31.

The side plate 31 comprises a plate body 31a, and the edge of the plate body 31a is provided with a flange 31b which is laterally outward. The flange 31b is provided with a flange gap corresponding to the rear end of the plate body 31a, and the flange gap forms the limit gap 6. The partial sections of the flange 31b at both ends of the flange gap form the front stop 6a and the rear stop 6b, respectively, and the stop 52 is located between the front stop 6a and the rear stop 6b.

The principle of the pedal rotation limiting structure is that when the pedal frame 3 rotates forward to the limit position, as shown in fig. 3, namely, the position of the leg support assembly 2 is not obstructed, and the comfortable placing posture of the foot when a human body sits is met, at this time, the front stop 6a is close to the stop part 52, the pedal frame 3 cannot rotate forward any more, and the leg support assembly 2 and the pedal frame 3 are located at the unfolding using position. When the pedal frame 3 rotates backward to the limit position, as shown in fig. 4, that is, the leg rest assembly 2 and the pedal frame 3 are located at the fixed storage position, the rear stopper 6b abuts against the stopper 52, and the pedal frame 3 can not rotate backward any more. In this embodiment, when leg support assembly 2 and pedal skeleton 3 were located fixed storage position, leg support assembly 2 was located perpendicularly seat skeleton 1 below, pedal skeleton 3 rotates fixedly to leg support assembly 2 back reduces the occupation to the car inner space.

As can be seen from fig. 1 and 3, the plate body 31a is an L-shaped flat plate including a first section near the recliner 4 and a second section near the cross bar 32. The first section of the plate body 31a forms a lower yoke plate of the angle adjuster 4, and the connecting part 51 of the limiting plate 5 forms an upper yoke plate of the angle adjuster. The first section is in transitional connection with the second section through an arc section, and the cross rod 32 is connected between the two second sections. The arrangement is such that when the leg rest assembly 2 and the foot pedal framework 3 are in the unfolding position, the cross bar 32 is positioned above the supporting surface of the leg rest assembly 2, and the feet of the passengers can be conveniently placed.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and those skilled in the art can make various similar representations without departing from the spirit and the scope of the present invention.
