The folding structure of the scooter

Abstract

This invention discloses a folding and clamping structure for a scooter, comprising a joint seat, a connecting tube, a folding mechanism, and a clamping mechanism. The connecting seat of the folding mechanism is located inside the connecting tube. One end of the handle passes through the connecting tube and the connecting seat. A first positioning shaft passes through the connecting seat and the connecting tube and is then engaged with the joint seat. The two ends of the rotating shaft pass through the connecting tube and are then connected to the joint seat, making the joint seat and the connecting tube pivotally connected. The second positioning shaft of the clamping mechanism passes through the clamping plate and is engaged with the joint seat. Fasteners connect the clamping plate and the connecting seat, while an elastic element is disposed between the fasteners and the clamping plate. The folding mechanism and the clamping mechanism provide a two-position locking effect and, by combining the clamping mechanism and the folding mechanism, reduce the wobbling of the connecting tube.

The second positioning shaft passes through the clamping plate and is detachably engaged with the joint seat. The fastener passes through the clamping plate and the connecting tube and is then assembled with the connecting seat of the folding device. The elastic element is disposed between the fastener and the clamping plate.

2. The folding and clamping structure of the scooter as claimed in claim 1, wherein the end edge of the joint seat is recessed to form at least two sets of first limiting grooves and one set of second limiting grooves, the two ends of the first positioning shaft of the folding device are detachably engaged in any set of the first limiting grooves, and the two ends of the second positioning shaft of the clamping device are detachably engaged in the second limiting groove.

3. The folding mechanism of the scooter as claimed in claim 1, wherein the handle of the folder has a rod portion and a rotating portion, the outer peripheral surface of the rod portion is formed with an external thread, one end of which is connected to the rotating portion, and the other end passes sequentially through the first groove of the connecting tube, the connecting seat and the second groove.

4. The folding mechanism of the scooter as claimed in claim 1, wherein the folder further comprises a torsion spring, one end of which is connected to the first positioning shaft and the other end of which is connected to the rotating shaft.

5. The folding and tightening structure of the scooter as claimed in claim 1, wherein the fastener of the tightener has a head and a locking rod, one end of the locking rod is connected to the head, and the locking rod passes through a locking hole of the tightening plate and a second groove of the connecting tube and is locked to the connecting seat of the folder, the elastic element is sleeved on the locking rod, and a first gap is formed between the head and the outer peripheral surface of the tightening plate.

6. The folding and clamping structure of the scooter as claimed in claim 1, wherein the clamping plate of the clamping device has a plate body and a protrusion, the protrusion protruding from the surface of one side of the plate body and forming a through hole through the protrusion, a locking hole through the plate body is formed at one end of the plate body, and the second positioning shaft passes through the through hole.

7. The folding and clamping structure of the scooter as described in claim 6, wherein one end of the clamping plate is further provided with a positioning hook, the positioning hook having an extension rod and a hook portion, the connecting seat of the folder forming a hanging groove, the extension rod of the positioning hook passing through the hanging groove of the connecting seat, the hook portion of the clamping plate and the plate being located on the inner and outer sides of the connecting seat respectively, and a second gap being formed between the outer peripheral surface of the hook portion and the inner peripheral surface of the connecting seat.

8. The folding structure of the scooter as claimed in claim 1, wherein a guide groove is formed on the left and right sides of the connecting tube, a side hole is formed on both sides of the connecting seat of the folding device, and the two ends of the first positioning shaft pass through the side holes of the connecting seat and the guide grooves of the connecting tube and are then detachably snapped into the joint seat.
