[0038] The terminology used in this utility model is for illustrative purposes only and is not intended to limit the scope of the utility model. The following description, in conjunction with the appendix, further clarifies this utility model. Figure 1-15 The following is a detailed description of some embodiments of this utility model.

[0039] This utility model discloses a folding, adjustable foot pedal for an integrated control seat, comprising a folding body 1, a rotating body 2, and a pivot assembly 3. Specifically, referring to Figure 1, the folding body 1 is fixed to a column, and the pivot assembly 3 connects the folding body 1 and the rotating body 2, enabling folding and unfolding functions.

[0040] Referring to Figures 1 and 2, the folding body 1 includes a folding body 11 and a magnetic block 12; the folding body 11 and the magnetic block 12 are connected by screws and fixed on the mounting column.

[0041] The folding body 11 includes a base 111, a locking assembly 112, and a tube 113; one end of the tube 113 is fixedly connected to the column, and the other end of the tube 113 is fixedly welded to the middle of one side of the base 111; the locking assembly 112 is symmetrically welded and fixed to the other side of the base 111.

[0042] Referring to Figure 7, the locking assembly 112 includes a guide cylinder 1121, a locking spring 1122, a limiting steel ball 1123, and a set screw 1124. One limiting steel ball 1123, one locking spring 1122, and one set screw 1124 are sequentially installed into the upper and lower ends of the guide cylinder 1121. The set screw 1124 ensures the force exerted by the locking spring 1122 on the limiting steel ball 1123, thereby guaranteeing the locking force of the locking assembly 112 when the foot pedal is extended.

[0043] Referring to Figure 1, the rotating body 2 includes a rotating assembly 21, a cover plate 22, a foot pedal 23, a pedal shaft 24, and a nut 25.

[0044] Referring to Figure 9, the rotating assembly 21 is assembled from a turntable 211, a first slider 212, a first compression spring 213, a second slider 214, and a second compression spring 215; referring to Figure 7, the turntable 211 is welded from a turntable body 2111 and a pin 2112.

[0045] Referring to Figure 8, the cover plate 22 is welded together from the cover plate body 221, the first positioning block 222, and the second positioning block 223. The relative positions of the first positioning block 222 and the second positioning block 223 on the cover plate body 211 correspond to the initial positions of the two annular grooves of the turntable 211. Referring to Figure 9, the turntable 211 is provided with two linear grooves and two annular grooves. The first slider 212 and the first compression spring 213 are installed in the first linear groove of the turntable 211, and the second slider 214 and the second compression spring 215 are installed in the second linear groove of the turntable 211.

[0046] One end of the pedal shaft 24 is connected to the turntable 211. The cover plate 22 passes through the pedal shaft 24 and embeds the first positioning block 222 and the second positioning block 223 into the first annular groove and the second annular groove, respectively.

[0047] Referring to Figure 1, the foot pedal 23 passes through the pedal shaft 24 and is embedded in the groove of the cover plate 22. At this time, the foot pedal 23 and the cover plate 22 rotate synchronously around the pedal shaft 24. The nut 25 is installed on the other free end of the pedal shaft 24 to prevent the foot pedal 23 from falling off.

[0048] Referring to Figure 10, the rotating shaft assembly 3 includes a rotating shaft 31, a bushing 32, a retaining ring 33, and a torsion spring 34. The rotating shaft 31 passes through the mounting holes of the base 111, the turntable 211, and the torsion spring 34. The retaining ring 33 is engaged in the groove at the end of the rotating shaft 31. The two ends of the torsion spring 34 act on the base 111 and the turntable 211 respectively to help the rotating body 2 return from the unfolded state to the folded state.

[0049] The foot pedal can be in a folded state or a working state. Figure 1 is a triaxial view of the folding step pedal mechanism in the folded state. At this time, the foot pedal 23 is attracted to the magnetic block 12, and the torsion spring 34 provides an inward tightening force to the turntable 211. The combined action of the two keeps the foot pedal stable in the folded state. When the foot pedal is needed, the rotating body 2 is opened with the foot to the working state as shown in Figure 3. Referring to Figure 7, the pin 2112 on the turntable 211 is inserted between the two limiting steel balls 1123 of the locking assembly 112. The locking spring 1122 compresses the limiting steel balls 1123 and acts on the pin 2112, thereby locking the rotating body 2 in the working state.

[0050] The foot pedal 23 can be adjusted to different angles to accommodate the needs of different occupants. The foot pedal 23 has three stable states: 90° (initial state), 40° (first-level state), and 20° (second-level state) with respect to the horizontal plane. Figures 3, 11, and 14 are schematic diagrams of these three states.

[0051] The initial state is that the foot pedal 23 is perpendicular to the horizontal plane. Referring to Figure 9, at this time, the first positioning block 222 in the cover plate 22 is at the starting position of the first annular groove on the turntable 211, and remains stable under the joint limitation of the first slider 212 and the first annular groove, and the foot pedal 23 is stable in the initial state.

[0052] When the foot pedal 23 is pressed and rotated, the foot pedal 23 drives the cover plate 22 to rotate along the pedal shaft 24. The first positioning block 222 on the cover plate 22 slides along the first annular groove on the turntable 211, pushing the first slider 212 in the rotating assembly 21 to slide along the first linear groove on the turntable 211, causing the first compression spring 213 to be compressed. Under the continuous force of the foot, the first positioning block 222 on the cover plate 22 continues to slide along the first annular groove on the turntable 211, and the first compression spring 213 begins to rebound. When the first positioning block 222 contacts the first slider 212 and the second positioning block 223 on the cover plate 22 contacts the second slider 214 in the rotating assembly 21, the foot pedal mechanism is in the first stage state as shown in Figure 11. Referring to Figure 13, with the first slider 212 and the first compression spring 213 jointly limiting the first positioning block 222 and the second slider 214 and the second compression spring 215 limiting the second positioning block 223, the foot pedal mechanism is stable in the first stage state.

[0053] Continuing to press down on the foot pedal 23 will break the force balance in the first-level state. The cover plate 22 continues to rotate together with the foot pedal 23. The second positioning block 223 on the cover plate 22 slides along the second annular groove on the turntable 211, pushing the second slider 214 in the rotating assembly 21 to slide along the second linear groove on the turntable 211, causing the second compression spring 215 to be compressed. Under the continuous force of the foot, the second positioning block 223 on the cover plate 22 continues to slide along the second annular groove on the turntable 211, and the second compression spring 215 begins to rebound. When the second positioning block 223 separates from the second slider 214, the second positioning block 223 just slides to the end of the second annular groove. At this time, the first positioning block also just slides to the end of the first annular groove, and the foot pedal mechanism is in the second-level state as shown in Figure 14. Referring to Figure 16, with the second slider 214, the second compression spring 215, and the second annular groove on the turntable 211 jointly limiting the second positioning block 223, the foot pedal mechanism is stable in the second-level state.
