DETAILED DESCRIPTION

[0023] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0024] like Figure 1-6 As shown, a scooter folding mechanism disclosed in the present invention may include: a folding seat mechanism and a telescopic tube mechanism and other components;

[0025] like Figure 1-6 As shown, the folding seat mechanism includes a folding lower seat 1, a folding upper seat 2, a folding handle 3, a first slide groove 4, a paddle 5, a spring 6, a hook 7, a fixing seat 8, a hook groove 9, an eccentric wheel 10, a fixing nut 11, and a fixing groove 12;

[0026] The folding upper seat 2 is hinged on the upper surface of the folding lower seat 1, the folding handle 3 is hinged on the side of the folding lower seat 1, the first slide groove 4 is opened on the side of the folding handle 3, the paddle 5 is slidably arranged in the first slide groove 4, the spring 6 is arranged in the first slide groove 4 and is between the paddle 5 and the top surface of the first slide groove 4, the hook 7 is arranged on the side of the paddle 5, the fixing seat 8 is arranged directly below the hook 7, the hook groove 9 is opened on the lower surface of the fixing seat 8 and is adapted to the hook 7, the eccentric wheel 10 is installed on the hinge shaft of the first slide groove 4, the fixing groove 12 is opened on the side of the folding upper seat 2, and the fixing nut 11 is installed on the side of the eccentric wheel 10 and is stuck in the fixing groove 12;

[0027] When folding, the lifting paddle 5 compresses the spring 6 and drives the hook 7 to move out of the hook groove 9, so that the limit on the folding handle 3 can be released. Then, the folding handle 3 is rotated around the hinge, and the fixing nut 11 is driven by the eccentric wheel 10 to move out of the fixing groove 12 on the folding upper seat 2, so that the fixation between the folding lower seat 1 and the folding upper seat 2 can be released. Then, the folding upper seat 2 is rotated around the hinge of the folding lower seat 1 and the folding upper seat 2 to achieve folding;

[0028] When unfolding, the folding upper seat 2 is rotated in the opposite direction to combine the folding lower seat 1 and the folding upper seat 2, and the lifting paddle 5 compresses the spring 6 while driving the hook 7 to move, and then the folding handle 3 is rotated in the opposite direction to drive the fixing nut 11 to snap into the fixing groove 12 of the folding upper seat 2 through the eccentric wheel 10, and then the folding handle 3 continues to rotate to move the hook 7 to the top of the hook groove 9, and then the paddle 5 is released to allow the spring 6 to rebound and drive the hook 7 to descend and snap into the hook groove 9 matched with it, and the folding handle 3 is fixed, and the operation is completed;

[0029] like Figure 1-6 As shown, the telescopic tube mechanism includes a main tube 13, a fixed block 14, a movable seat 15, a threaded hole 16, a screw 17, a positioning hole 18, a clamp 19, a second slide groove 20, a knob 21, and a secondary tube 22;

[0030] The main pipe 13 is installed at the center of the upper surface of the folding upper seat 2, the fixed block 14 is slidably arranged in the main pipe 13, the second slide groove 20 is opened on the side of the main pipe 13, and multiple positioning holes 18 are evenly opened on the side of the main pipe 13 and on one side of the second slide groove 20. A cavity is opened in the fixed block 14, and the movable seat 15 is slidably arranged in the cavity. The threaded hole 16 is opened on the side of the movable seat 15, and the screw 17 is arranged in the threaded hole 16. The knob 21 is installed at the end of the screw 17 extending from the second slide groove 20 to the outside of the main pipe 13, the clamp 19 is installed on the other side of the movable seat 15 and is clamped in one of the positioning holes 18, and the auxiliary pipe 22 is installed on the upper surface of the fixed block 14 and is adapted to the main pipe 13;

[0031] When adjusting the length of the telescopic tube mechanism, the rotating knob 21 drives the screw 17 to rotate, and the rotating screw 17 drives the moving seat 15 to move. The moving moving seat 15 drives the clamping piece 19 to move out of the positioning hole 18, so that the fixation between the auxiliary tube 22 and the main tube 13 can be released. Then, the auxiliary tube 22 is pulled up to drive the fixing block 14 and its internal components to move until the length of the telescopic tube mechanism reaches a predetermined height. Then, the auxiliary tube 22 is fine-tuned to align the clamping piece 19 with the nearest positioning hole 18. Then, the reverse knob 21 drives the screw 17 to reverse and drive the moving seat 15 to move in the opposite direction so that the clamping piece 19 is clamped into the aligned positioning hole 18, so that the auxiliary tube 22 and the main tube 13 are fixed, and the length adjustment is completed.
