Detailed Description

As shown in fig. 1-3, a folding mechanism for a scooter, comprises a fixed seat 1, a movable seat 2, and a handle 3, wherein the handle 3, the movable seat 2 and the fixed seat 1 are sequentially sleeved from inside to outside, and the handle 3, the movable seat 2 and the fixed seat 1 are hinged to form a positioning axis 4. The fixing base 1 is connected with the vehicle body, the movable base 2 is connected with the handlebar, the fixing base 1 and one end face of the movable base 2 are provided with notches for being sleeved, and the handle 3 is located at the innermost side.

The upper portion and the lower portion of the fixing seat 1 are respectively provided with a first positioning hole 5 and a second positioning hole 6, the first positioning hole 5 and the second positioning hole 6 are both linear structures, and the linear structures can be linear or curved, and are specifically determined by actual production.

Be equipped with movable groove 7 on the sliding seat 2, movable groove 7 has continuous last slot part 8, transition portion 9 and lower slot part 10, go up slot part 8 and transition portion 9 between, the junction between slot part 10 and the transition portion 9 all has the corner down, is the spill shape on the overall structure.

The upper groove part 8 corresponds to the first positioning hole 5, the lower groove part 10 corresponds to the second positioning hole 6 in shape and position, a movable pin 11 and a positioning pin 12 are further arranged between the fixed seat 1 and the movable seat 2, the positioning pin 12 is arranged at the second positioning hole 6, and the movable pin 11 is arranged at the first positioning hole 5 and the movable groove 7. Since the movable groove 7 moves along with the rotation of the movable seat 2, the corresponding relationship between the upper groove portion 8 and the lower groove portion 10 is maintained in a relative state. The movable pin 11 reciprocates in the movable groove 7 according to the interlocking relationship, while the positioning pin 12 is kept relatively constant by the influence of the elastic force.

Elastic connection has the trend of leaning on mutually between activity round pin 11 and the locating pin 12, handle 3 has manual end 13 keeping away from location axle center 4 one end, handle 3 has false touch end 14 and butt end 15 in location axle center 4 periphery, false touch end 14 and butt end 15 all pass through the butt linkage with activity round pin 11, false touch end 14 relative radial extension is less than the radial extension of butt end 15, butt end 15 rotates the route and covers activity groove 7, false touch end 14 rotates the route and covers only activity groove 7's last slot part 8/slot part 10 down. The dummy contact 14 is rotated to push only the movable pin 11 entering the upper groove portion 8 or the lower groove portion 10, and due to the limited pushing distance, the movable pin 11 can be easily restored to its original position if the dummy contact 14 is separated from the upper groove portion 8 or the lower groove portion 10.

The utility model discloses a handle of fixing base 1, including locating axle center 4, locating shaft center 16, connecting rod 17, locating pin 12, locating shaft center 4 department is equipped with the axle center pole 16 that runs through handle 3, sliding seat 2 and fixing base 1, be equipped with connecting rod 17 between axle center pole 16 and the locating pin 12, the department of leaning on locating pin 12 on the connecting rod 17 is equipped with stop nut 18, the last hook hole that supplies elastic connection that is equipped with of stop nut 18. Make things convenient for the installation of spring, through connecting rod 17 and cooperation part, strengthen stability and reliability among the linkage process.

The periphery of the axle center rod 16 is also provided with an auxiliary rod 19, the auxiliary rod 19 is provided with a limiting piece 20, and the limiting piece 20 is respectively lapped with the axle center rod 16 and the connecting rod 17. Reduce vibrations and reduce the probability of breaking away from, improve structural stability. The overlapping is only a certain interference and separation effect after the butting, and is not completely limited.

The false touch end 14 and the butt end 15 are both hollow structures, so that the production cost is reduced, the weight is reduced, the structural strength can be ensured, and the service life can be prolonged.

Manual end 13 is the bended-arc structure, and manual end 13 circular angle degree is greater than 180 degrees for the tip orientation is downward, improves the safety in utilization.

The working principle is summarized as follows: in the folding process, the handle 3 is pulled backwards, and the movable pin 11 is pushed by the false touch end 14 to be temporarily removed from the upper groove part 8; with the further rotation of the handle 3, the dummy contact end 14 does not further push the movable pin 11, and the movable pin 11 elastically resets and is clamped between the dummy contact end 14 and the abutting end 15; at this time, the movable pin 11 locks the upper groove portion 8 and the movable seat 2 cannot rotate, and the handle 3 is pulled again, so that the abutting end 15 pushes the movable pin 11 to be separated from the upper groove portion 8 again, and the movable seat 2 is rotated to be folded; the movable pin 11 is driven by the movable seat 2 from the upper groove portion 8 to the lower groove portion 10 through the transition portion 9, and the locking effect is achieved in the lower groove portion 10.

During the unfolding process, the handle 3 is pulled similarly so that the abutment end 15 pushes the movable pin 11, thus disengaging from the lower slot portion 10; rotating the movable seat 2 to enable the movable pin 11 to reversely return to the position of the upper groove part 8 for locking; finally, the handle 3 is pushed back again once again with the safety feature, and the movable pin 11 is again brought into position between the manual end 13 and the dummy end 14.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing and simplifying the description, but do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and therefore, are not to be considered as limiting the present invention, and that the fundamental principles, the main features, and the advantages of the present invention are shown and described above, as would be understood by those skilled in the art.
