The first mounting portion 12a is integrally formed with a guide plate 120 in the direction of the inner side, and a sliding trend toward the outer side of the seat portion 10 can be exposed. The guide plate is provided with a plurality of positioning grooves 1 2 1. A traction section 16, as shown in FIGS. 5 a and 6, includes a shaft pin 1 6 2 which is rotatably supported on a pair of bearings 1 6 1, and the pair of bearings 1 6 1 is fixed on the pedal 1 4 The rear part; the lower part of the traction part 16 is between the two bearings 16 1 'is sealed to the guide plate 1 2 0 on the first mounting part 1 2 a, and a guide groove 1 6 7 is formed to guide the The guide plate i 2 〇 glides. The front end of the shaft pin 1 6 2 includes a positioning pin 16 3 and a bracket 164 fixed on the bearing 16 1 and an adjustment bolt 164 is provided for adjusting and positioning the protruding position of the pedal 14. The shaft pin 1 6 2 includes a fixing element i 6 5 above; and the traction portion 16 causes the front positioning pin 1 6 3 to have a downward buckle by the potential energy of a torsion spring 1 6 6 disposed on the shaft pin 16 2 The trend. 200528323 A winding section 17 as shown in Figures 4 and 4a, including a first reel 171 and a second reel 173 in the upper and lower positions, wherein the first reel 171 is integrally formed with a The intermediary disk 172 is interposed between the first reel 171 and the second reel 1 73, and the two are pivoted on the extension portion 1 3 through the same pin 174. The second reel 173 and the intermediary disk 172 The first and second reels 171 and 173 are linked in a controlled manner via a clutch device 172 ', and recesses 1 7 1 1 and 1 7 3 1 are formed along the circumferential surfaces. The clutch device 172 'includes an annular groove 1721 formed on the interface of the intermediary disk 172 facing the second reel 173, and a protruding pin 1 722 is provided on a fixed point on the outer peripheral surface of the protruding pin 1 722. Outside the diameter, the other end passes through the annular groove 1 7 2 1 and a buffer spring 1 7 2 3 is fixed in the annular groove 1 7 2 1, and the interface of the second reel 173 facing the intermediary disk 172 corresponds to A linking pin 173 is provided at a fixed point of the annular groove 1721, and protrudes in the annular groove 1721, so that the second reel 173 and the intermediary disc 172 can be restrained and linked. Among them, a disc-shaped plate spring 175 is provided above the first reel 171, and the potential energy of the leaf spring 174 is stored, so that it has resistance in the opposite direction when unwinding; and a disc-shaped plate is provided below the second reel 173 The spring 175, with the potential of the leaf spring 176, can resist it in the opposite direction when unwinding. A first steel cable 18, one end of which is connected to the fixing element 16 of the traction part 16 of the foot pedal 14 and the other end is wound at least two times in the recess 1711 of the first reel 17 丨 and anchored The second mounting portion 12b is provided with a plurality of steering pulleys 1 8 1 to guide the first steel cable 18. A second steel cable 19, one end of which is anchored on the disc surface of the second reel 173, and the remaining length is wound at least two times in the recess 1 7 3 1 and the other end is threaded in a protective lead 丨 9 a And -9-200528323 is connected to the sliding element 22 of the door 21. According to the present invention, the length of the foot pedal 14 is approximately equal to the circumference of the first reel 1 71, that is, the first reel i 7 1 unwinds the cable once; and, the second reel 173 The perimeter is greater than twice the circumference of the first reel 171, which is equivalent to the width of the door opening. When the door 21 is normally closed, the second steel cable 19 and the first steel cable 18 are pulled by the door 21 to pull the foot pedal 14 to the retracted position. At this time, the first steel cable The remaining length of 18 is wound on the first reel 171, and the second reel 173 is in the state of unwinding the second steel cable 19, and has the potential energy of the plate spring 176. When opening the door, you can get a better understanding through Figure 3 and Figure 4. The direction of the arrow in the figure shows the direction of the door opening and the linkage of the mechanism. When the door 21 is driven, the pedal 14 is pulled by the tension of the spring 15 The seat portion 10 extends outwardly. At this time, the first reel 17 1 passively unwinds the first steel cable 18, and the second reel 173 is affected by the disc leaf spring 176 and starts to release the door 21. The remaining length is wound on the concave portion 1 7 3 1 on the peripheral surface until the foot pedal 14 reaches the positioning at the end of the door opening. Since the stroke of the door 21 is greater than the stroke of the foot pedal 14, the second reel 1 73 is separate. Continue to complete the trip. Please refer to FIG. 6 again. From another aspect, when the foot pedal 14 is extended, the guide plate 120 of the first mounting portion 12a slides in the guide groove 167 of the traction portion 16, because a bracket is fixed at the rear end of the traction portion 16. 164 is also provided with an adjusting bolt 1 6 8 for adjusting the length of the foot pedal 1 4 protruding. Therefore, when the entire foot pedal 1 4 is extended to the set position, the guide plate 20 meets the adjusting bolt 1 6 When the 8 can no longer slide, the first steel cable 18 loosens the traction section 16 and the traction section 16 the shaft pin 1 02 is rotated by the torsion spring 1 66 in a clockwise direction so that the positioning pin 1 6 3 at the front end is buckled. Insert the set -10- 200528323 positioning groove 1 2 1 below (as shown in Figures 5 and 7). Please refer to Figure 5 and compare with Figure 7. The direction of the arrow in the figure shows the direction of the door closing and the linkage of the mechanism. When the door 2 1 is closed, the second reel 1 7 3 is first unwound a small section of the second steel cable 19. That is, the travel of the door 2 1 is greater than the foot pedal 1 4, and then the interlocking pin 1 7 3 2 on the second reel 1 7 3 contacts the buffer spring 1 on the intermediate plate 172 protruding pin 1 72 2 through a certain point. 723, and pushing the protruding pin 1 722 interlocked the first reel 17 1 to start winding the first cable 18 and retract the foot pedal 1 4; on the other hand, when the first reel 1 7 1 began to roll When winding, the first steel cable 18 is pulled to cause the positioning pin 16 of the traction portion 16 to rise upward to leave the positioning groove 1 2 1 of the guide plate 1 20, and release the pedal plate 1 4 to be buckled; the rest are reversed. In other words, I will not repeat them here. The above are only preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention; that is, equivalent changes and modifications made without departing from the scope of patent application of the present invention should still fall within the scope of the present invention. To sum up, the automatic telescopic foot pedal for the vehicle of the present invention does not need to cut the sheet metal of the vehicle body during installation, and does not require any manual or electric, hydraulic, pneumatic and other power assistance, and is easy to install.
