Detailed ways

For the convenience of a deeper understanding of the present invention, the details are as follows:

The scooter folding device of the present invention is connected between the front end of the pedal and the vertical pole of the front of the car, and the front folding device includes a steering seat, a shaft rod, a connecting piece and a sliding sleeve. Wherein, the steering seat is combined with the front end of the pedal, the top of the steering seat is provided with a first positioning part, and one side of the steering seat is provided with a stopper; the shaft is pivotally connected with the steering seat, and the top of the shaft is provided with a sliding part; The connecting piece is connected to the bottom end of the vertical pole, and the connecting piece is connected to the sliding part in a manner that can rotate relative to the shaft and move to a limited extent; while the sliding sleeve is sleeved on the vertical pole in a manner that can slide axially relative to the shaft The bottom end of the sliding sleeve is provided with a second positioning part, and the side of the bottom end of the sliding sleeve is provided with a stopper.

Please refer to Fig. 1, Fig. 2 and shown in Fig. 3, which is a preferred embodiment of the scooter folding device 1 of the present invention, the front folding device 1 is connected between the front end of a pedal 9 and the vertical rod 91 of a front, It includes a steering seat 2 , a stopper 3 , a shaft 4 , a connecting piece 5 and a sliding sleeve 6 .

The steering seat 2 includes a sleeve 21 and a base 22, the top of the sleeve 21 is provided with an external thread, and the external thread is used as the first positioning part 211; the rear end of the base 22 is roughly arc-shaped, and its bottom combines At the front end of the pedal 9 , the front end of the base 22 has a shaft hole 221 through which the sleeve 21 is coaxially sleeved, and the sleeve 21 is combined with the upper half of the shaft hole 221 . A rearwardly extending protrusion 222 is provided on the rear side of the base 22 . A space 223 is formed inside the protrusion 222 . The space 223 has an upper channel 224 communicating upward and a side channel 225 communicating backward.

This stopper 3 comprises a stop bar 31, a handle 32 and an elastic member 33, and the stop bar 31 is a straight bar passing through the upper hole 224, and the front end of the handle 32 is connected to the stop after passing through the side hole 225. The moving rod 31 is connected; and in this embodiment, the elastic member 33 is a spring, which is positioned in the space 223 inside the protruding block 222 and is located below the stop rod 31 .

The shaft 4 is pivotally connected to the base 22 of the steering seat 2, the bottom end of the shaft 4 is connected to the front wheel 92, and the top end of the shaft 4 is provided with a sliding part 41, which is an axially extending sheet , the two sides of the sheet form mutually parallel outer surfaces 411 , and the sheet is provided with a perforation 412 passing through the two outer surfaces 411 .

The connecting piece 5 is a circular straight rod connected to the bottom end of the vertical rod 91. The connecting piece 5 is provided with an axial guide rail 51 and a radial guide groove 52 with an opening formed at the bottom end, wherein the axial guide rail 51 is formed on each other. Between the two parallel inner surfaces 511 , the distance between the two inner surfaces 511 is slightly greater than the distance between the two outer surfaces 411 of the sliding part 41 , so that the sliding part 41 is accommodated in the axial guide rail 51 . The radial guide groove 52 is formed on the side wall of the connector 5. When a radial pin 53 passes through the through hole 412 of the sliding part 41, both ends of the radial pin 53 are accommodated in the radial guide groove 52, So that the connecting piece 5 can rotate relative to the shaft rod 4 and move axially up and down to a limited extent.
