【Detailed ways】

The utility model is a folding structure, as shown in Figures 1 to 11, comprising a first swing body 2 with a pair of coupling pieces 1, a second swing body connected between the pair of coupling pieces 1 through a swing shaft 3 4. As well as the folding mechanism 5, in the first, second and third embodiments, the folding structure is applied to the scooter, wherein: in the first and second embodiments (as shown in Figures 1 to 7), the first swinging body 2 is the pedal of the scooter, and the second oscillating body 4 is the fork tube of the scooter; and in the third embodiment (as shown in Figures 8 to 11), the first and second oscillating bodies 2 and 4 are respectively the forks of the scooter. Upper link for bushings and pedals. The coupling sheet 1 is respectively provided with an expansion slot 11 and a retraction slot 12; the section of the outer wall of the coupling sheet 1 between the expansion slot 11 and the storage slot 12 is based on the swing axis 3 is the arc-shaped surface 13 at the center of the circle; the folding mechanism 5 includes a retractable control 51 that is swingably connected in the middle of the second swinging body 4, is provided in the buttonhole 41 of the second swinging body 4 and is controlled by an external force ( When folded, it is kicked, and when it is unfolded, it is pressed by hand), which can push the pressing part 52 of the retractable control 51 to swing, the retractable pin 53 that is driven by the retractable control 51 and leaves the card slot, and the retractable control 51. The retracting pin 53 is pulled toward the return spring 54 of the swing shaft 3; the two ends of the retracting pin 53 slide left and right along the arc surface 13 of the coupling piece 1 and then slide down to the unfolding slot 11 and the retracting slot respectively. 12; the pressing member 52 is exposed from the button hole 41 of the second swinging body 4; the two sides of the second swinging body 4 are respectively provided with a retractable pin limit bar-shaped groove 42, and when it is folded or unfolded Make folding pin 53 slide in the strip groove all the time when car body. When the car body is in the unfolded state, as shown in Figures 1 and 5, the folding pin 53 falls into the expansion slot 11 of the coupling piece 1. When the car body is to be folded, the operator presses or steps on the pressing part 52 to make it slide or swing into the buttonhole 41 of the second swinging body 4, at this time the pressing member 52 acts on the retracting control 51 to make it counterclockwise (as shown in the first and second embodiments of Figures 1 to 7) or clockwise (as shown in the third embodiment of Figures 8 to 11), so that the retractable control 51 makes the retractable pin 53 slide toward the notch of the unfolded card slot 11 after overcoming the force of the return spring 54, once The folding pin 53 slides away from the unfolding slot 11 to start folding the car body. At this time, the hand or foot on the pressing piece is released, and the first and second swing bodies 2, 4 are swung together, and the pressing piece 52 is reset. 1. The folding pin 53 slides toward the folding slot 12 along the arc surface 13 until it falls into the folding slot 12 under the pull of the return spring 54 to complete the folding, as shown in FIGS. 2 and 9 . When the car body in the folded state is to be unfolded, press the pressing member 52 with your hand to make the pressing member 52 slide or swing in the second swinging body 4 again, which makes the unfolding control 51 counterclockwise again (as shown in Figure 1 to 7) or clockwise (as shown in Figure 8 to Embodiment 3) to slide the retractable pin 53 away from the retractable slot 12, once the retractable pin 53 completely slides away from the retractable Combining the card slot 12, the car body can be launched.

As can be seen from the above, since the folding mechanism 5 only has four parts, the retracting control 51, the pressing member 52, the folding pin 53 and the return spring 54, the folding structure of the entire vehicle body is simpler, the operation is convenient, and the production The cost is lower; in addition, when the car equipped with this folding structure is walking, under the action of human body gravity, the upper inclined wall 111 of the coupling plate expansion slot always has a force acting on the folding pin, so that even when walking If you accidentally touch (mainly step on) the pressing piece 52, it is also difficult to push the retractable control 51 to swing to push the folding pin 53 out of the unfolding slot 11, so that you will not be injured by accidentally touching the pressing piece while walking. The vehicle body is automatically folded and danger occurs, so the structure of the utility model is more reasonable and the safety is higher.

In embodiments one to three shown in Figures 1 to 11, the utility model is applied on a scooter, and at this time, the vehicle body is usually folded with a foot button, so there is no need to squat down or bend down to fold the body, so that The folding operation of the car body is greatly facilitated. When the scooter is to be unfolded, the button is pressed by hand; of course, when the folding structure is applied to other car bodies, the button can also be pressed by hand to unfold or fold the scooter.

In the first embodiment shown in Figures 1 to 4, the pressing member 52 slides linearly in the second swinging body 4 to push the expansion control 51 to swing counterclockwise. In addition, in this embodiment, due to the second swinging The body 4 is shell-shaped and relatively thin, and the pusher 52 is easy to shake in the thin buttonhole 41. For this reason, the second swing body 4 is provided with a cover plate 6 with a buttonhole 61 to give the pusher 52 The straight-line sliding provides guidance and avoids shaking, thereby providing guidance for the sliding in and out of the folding pin and making it slide more smoothly. In the second embodiment shown in Figures 5 to 7, the pressing member 52 is oscillatingly connected in the second oscillating body 4, and when it oscillates into the second oscillating body 4, it can push the expansion control 51 to swing counterclockwise. Fold or unfold the body. In the third embodiment shown in FIGS. 8 to 11 , the pressing member 52 is also oscillatingly connected to the second oscillating body 4 . To sum up, the pressing member can push the extension control to swing in the buttonhole 41 of the second swing body 4 either in a linear sliding manner or in a swinging manner.

In Embodiments 1, 2, and 3, the return spring 54 is a tension spring, and its two ends are respectively hooked on the middle position of the folding pin 53 and the swing shaft 3 so that the force of the folding pin is stable. The control 51 is provided with a tension spring passing through the escape groove 511 . Of course, the return spring can also be a compression spring or the like.

Preferably, as shown in FIGS. 1 to 11 , a coupling cover for covering the unfolding slot 11 , the retracting slot 12 and the retracting pin limiting strip groove 42 is provided on the outer surface of the coupling piece 1 7. In addition to preventing people from being pinched when reaching into the groove, it can also make the folding structure more beautiful.

In Embodiments 1 to 3, the folding pin 53 always falls in the curved portion of the retracting control 51, so that the retracting control 51 pulls the folding pin 53 to leave the unfolding or folding slot.

Although the present utility model has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that the present utility model can be modified without departing from the principle and spirit scope of the present utility model defined by the claims. Various changes or modifications are made to the utility model. Therefore, the detailed description of the embodiments of the present disclosure is only for explaining, not for limiting the utility model, but the scope of protection is defined by the content of the claims.
