The vehicle's front-controlled card release and retraction structure

Abstract

A front-controlled latching and folding structure for a vehicle includes a first vehicle body, a second vehicle body, a folding / unfolding latch assembly, and an operating assembly. The first vehicle body has a first folding / unfolding pivot and a lever movable slot. The second vehicle body has a second folding / unfolding pivot pivot pivotally connected to the first folding / unfolding pivot, a folding / unfolding slot, and a first operating pivot. The folding / unfolding latch assembly is disposed in the lever movable slot and has a latch lever that can engage or disengage from the folding / unfolding slot. The operating assembly has a second operating pivot pivotally connected to the first operating pivot and a linkage that disengages the latch lever from the folding / unfolding slot when actuated. This allows the locking state of the first and second vehicle bodies to be released with a single operation, enabling the second vehicle body to fold relative to the first vehicle body and automatically return to its engaged position when unfolded, thereby improving the convenience, smoothness, and safety of the folding / unfolding operation.

Claims

1. A front-controlled latching and folding structure for a vehicle, comprising: a first vehicle body having a first retraction pivot and a lever movable slot; a second vehicle body having a second retraction pivot pivot pivotally connected to the first retraction pivot pivot of the first vehicle body via a pivot, a retraction slot, and a first operating pivot; a retraction latch assembly having a latch lever movable in the lever movable slot of the first vehicle body, the latch lever being displaceable to enter or exit the retraction slot of the second vehicle body to engage or disengage with the retraction slot; and an operating assembly having an operating member having a second operating pivot pivot pivotally connected to the first operating pivot pivot of the second vehicle body via an operating pivot, an operating part for user to apply force to operate, and a linkage part that, when the operating assembly is activated, actuates the retraction latch assembly to disengage the latch lever from the retraction slot of the second vehicle body.

2. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The rod movable slot of the first vehicle body is located in front of the first retraction pivot.

3. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The position of the rod movable groove of the first vehicle body is higher than the position of the first retraction pivot.

4. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The second vehicle body has a retractable part, which is stepped on by the user after the lever is disengaged from the retractable slot to fold the second vehicle body relative to the first vehicle body.

5. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The second vehicle body also has a stop groove, and the operating assembly also has a stop protrusion that stops the stop groove of the second vehicle body, so that the second vehicle body and the operating assembly can be linked.

6. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The second vehicle body also has a locking guide edge that pushes against the locking lever of the retractable locking assembly when returning from the folded state to the unfolded state.

7. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The retractable card assembly has a spring connector and a first spring connected between the card rod and the spring connector, the first spring being used to force the card rod to engage with the retractable card slot.

8. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The operating assembly also has a second spring for returning the operating assembly to its original position and for disengaging the linkage from the lever of the retractable card assembly.

9. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The first vehicle body has a first fastener, and the second vehicle body has a second fastener that engages with the first fastener of the first vehicle body when it is in a folded state.

10. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The first vehicle body has a first frame and a handlebar assembly rotatably connected to the first frame.

11. The front-controlled card release and retraction structure of the vehicle as described in claim 1, wherein, The second vehicle body has a second frame and a footboard provided on the second frame for the user to stand on or step on.
