DETAILED DESCRIPTION

[0029] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 5 As shown, a folding structure of a scooter is mainly used on a scooter, including a planar connecting rod mechanism, the planar connecting rod mechanism includes a pedal seat 1 and a handlebar 2, the handlebar 2 is hinged on the pedal seat 1, and the handlebar 2 can rotate vertically on the pedal seat 1.

[0031] Specifically, the handle bar 2 is hinged on the pedal seat 1 through the first rotating shaft 71. By rotating the handle bar 2, the handle bar 2 can be folded or unfolded on the pedal seat 1, which is equivalent to the handle bar 2 having a folded position and an unfolded position on the pedal seat 1, which solves the problem that the scooter is inconvenient to carry and occupies a large space.

[0032] When the handle bar 2 is in the folded position, the angle between the handle bar 2 and the pedal seat 1 is approximately 0°; when the handle bar 2 is in the unfolded position, the angle between the handle bar 2 and the pedal seat 1 is approximately 90°.

[0033] The planar linkage mechanism also includes a follower, which is connected between the pedal seat 1 and the handle bar 2. When the handle bar 2 is folded on the pedal seat 1, the planar linkage mechanism is in a dead point position. At this time, the pressure angle is 90°, and the force or torque exerted by the handle bar 2 on the follower is zero. At this time, the handle bar 2 cannot drive the follower to move, which is equivalent to the handle bar 2 being fixedly set on the pedal seat 1.

[0034] When the handle bar 2 is unfolded on the pedal seat 1, the planar connecting rod mechanism is also in a dead point position. At this time, the pressure angle is 90°, and the force or torque exerted by the handle bar 2 on the follower is zero. At this time, the handle bar 2 cannot drive the follower to move, which is equivalent to the handle bar 2 being fixed on the pedal seat 1.

[0035] In the folding structure of the scooter, when the scooter is folded or unfolded on the pedal seat 1, the planar connecting rod mechanism is in a dead point position, the handle bar 2 and the pedal seat 1 are fixed together, and the user cannot directly drive the handle bar 2 to rotate on the pedal seat 1, but can drive the handle bar 2 to rotate on the pedal seat 1 through a follower. Compared with the connection structure of the boss and recess in the prior art, the folding structure of the scooter has the advantages of simple structure, firm and reliable connection and simple operation.

[0036] The planar connecting rod mechanism can be a crank rocker mechanism or a crank slider 4 mechanism. Specifically, the planar connecting rod mechanism is a planar four-bar mechanism. The follower includes a connecting rod 3 and a slider 4. The pedal seat 1, the handle bar 2, the connecting rod 3 and the slider 4 constitute a planar four-bar mechanism. The connecting rod 3 is hinged on the pedal seat 1. The connecting rod 3 is hinged on the pedal seat 1 through the second rotating shaft 72. The rotation direction of the connecting rod 3 on the pedal seat 1 is consistent with the rotation direction of the handle bar 2 on the pedal seat 1. The slider 4 is hinged on the connecting rod 3 and slidably set on the handle bar 2. The slider 4 is hinged on the connecting rod 3 through the third rotating shaft 73. The rotation direction of the slider 4 on the connecting rod 3 is consistent with the rotation direction of the connecting rod 3 on the pedal seat 1.

[0037] When the handle bar 2 is folded or unfolded on the pedal seat 1, the sliding direction of the slider 4 and the rotation direction of the connecting rod 3 are on the same straight line. At this time, the pressure angle is 90°. The user cannot directly drive the handle bar 2 to rotate, which is equivalent to the handle bar 2 and the pedal seat 1 being fixed together.

[0038] When the handle bar 2 and the pedal seat 1 are fixed together, the user can directly drive the slider 4 to slide on the handle bar 2, so that the planar connecting rod mechanism is out of the dead point position, which facilitates the adjustment of the handle bar 2 between the folded position and the unfolded position, and further facilitates the operation of the folding structure of the scooter.

[0039] The pedal seat 1 is provided with a limiting groove 11, the lower end of the handle rod 2 is inserted into the limiting groove 11, and the first rotating shaft 71 is located in the limiting groove 11. When the handle rod 2 is folded on the pedal seat 1, the handle rod 2 abuts against the inner side wall on one side of the limiting groove 11, and when the handle rod 2 is unfolded on the pedal seat 1, the handle rod 2 abuts against the inner side wall on the other side of the limiting groove 11. The limiting groove 11 serves to limit the rotation angle of the handle rod 2 on the pedal seat 1, and also facilitates the handle rod 2 to be quickly positioned to the folded position or the unfolded position during the rotation process.

[0040] An elastic member 6 is arranged between the handle rod 2 and the slider 4. Specifically, the elastic member 6 is a coil spring. The elastic member 6 can force the handle rod 2 to remain in contact with the inner wall, so that the handle rod 2 remains folded or unfolded on the pedal seat 1. Specifically, when the handle rod 2 is folded on the pedal seat 1 and abuts against the inner wall on one side of the limiting groove 11, the handle rod 2 remains in contact with the inner wall on that side of the limiting groove 11 under the elastic force of the elastic member 6; and when the handle rod 2 is unfolded on the pedal seat 1 and abuts against the inner wall on the other side of the limiting groove 11, the handle rod 2 remains in contact with the inner wall on that side of the limiting groove 11 under the action of the elastic member 6.

[0041] In actual use of the scooter, the slider 4 will be affected by non-artificial external forces such as vibration and shaking. The elastic member 6 can offset such non-artificial external forces, thereby preventing the slider 4 from driving the planar connecting rod mechanism out of the dead point position under the action of non-artificial external forces, thereby improving the reliability and safety of the folding structure of the scooter.

[0042] The slider 4 is provided with a seating groove 42, and the elastic member 6 is arranged in the seating groove 42. A positioning rod 74 is detachably provided on the handle bar 2. One end of the elastic member 6 abuts against the inner bottom of the seating groove 42, and the other end of the elastic member 6 abuts against the positioning rod 74. By disassembling and assembling the positioning rod 74, the elastic member 6 can be easily disassembled and assembled in the seating groove 42.

[0043] The connecting rod 3 is arranged in the limiting groove 11, so as to avoid the problem that the connecting rod 3 is exposed to the outside and foreign objects may get stuck in the connecting rod 3, thereby improving the reliability of the planar connecting rod mechanism and the aesthetics of the folding structure of the scooter.

[0044] The handlebar 2 includes a hollow tube body 21, and a slider 4 is slidably arranged in the tube body 21. The slider 4 can slide in the tube body 21 along the length direction of the tube body 21. The slider 4 adopts a built-in structural design to avoid the problem of the plane connecting rod mechanism being directly exposed to the outside and the plane connecting rod mechanism being stuck by foreign objects, thereby improving the reliability of the use of the plane connecting rod mechanism. In addition, the design of the slider 4 being built in the tube body 21 also improves the compactness of the structure and reduces the occupied space. Therefore, the folding structure of the scooter has the advantages of reliable operation, small occupied space and beautiful appearance.

[0045] A first avoidance groove 211 is provided at the lower end of the tube body 21, and a second avoidance groove 41 is provided at the lower end of the slider 4. The connecting rod 3 is sequentially inserted into the first avoidance groove 211 and the second avoidance groove 41. The design of the first avoidance groove 211 and the second avoidance groove 41 prevents the tube body 21 and the slider 4 from hindering the rotation of the connecting rod 3, further improving the compactness of the structure and reducing the occupied space.

[0046] The handlebar 2 also includes a rod sleeve 22, which is sleeved on the tube body 21. The rod sleeve 22 is interference fit on the tube body 21, and the rod sleeve 22 is located at the lower end of the handlebar 2. When the handlebar 2 is folded or unfolded on the pedal seat 1, the rod sleeve 22 directly abuts against the inner wall of the limiting groove 11. The user can reduce the assembly error of the handlebar 2 and the pedal seat 1 by replacing the rod sleeves 22 of different sizes, so that when the handlebar 2 is folded or unfolded, the planar connecting rod mechanism can be in the dead point position.

[0047] A third avoidance groove 221 is formed on the rod sleeve 22 , and the third avoidance groove 221 is designed to prevent the rod sleeve 22 from hindering the rotation of the connecting rod 3 .

[0048] The handle bar 2 is provided with a handle cover 5, and the overall structure of the handle cover 5 is in the shape of a tube body 21. The handle cover 5 is fixedly arranged on the slider 4. When the handle bar 2 needs to be rotated, the user can hold the handle cover 5 to drive the slider 4 to slide, and then drive the handle bar 2 to rotate, thereby further facilitating the operation of the folding structure of the scooter.

[0049] The tube body 21 is provided with a first strip hole 212 , and the third rotating shaft 73 is passed through the first strip hole 212 . The third rotating shaft 73 is limited to slide in the first strip hole 212 , thereby limiting the sliding stroke of the slider 4 on the tube body 21 .

[0050] The tube body 21 is further provided with a second strip-shaped hole 213 , and a pin rod 75 is inserted into the second strip-shaped hole 213 . The pin rod 75 fixes the slider 4 in the tube body 21 and the handle cover 5 outside the tube body 21 together.

[0051] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made to the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
