Detailed Description

Examples

As shown in fig. 1 to 4, a scooter frame comprises a front rod 10, a rear rod 11, a handle rod 12 and a seat rod 13, wherein the rear rod 11 is movably connected to the front rod 10 along the length direction of the front rod 10, the lower side of the seat rod 13 is hinged with the rear side of the front rod 10, the lower side of the handle rod 12 is hinged with the rear side of the rear rod 11, and the seat rod 13 is hinged with the handle rod 12, so that the rear side of the front rod 10, the rear rod 11, the lower side of the handle rod 12 and the lower side of the seat rod 13 form a triangle structure.

The rear lever 11 is inserted into the front lever 10, and the hinge point of the handle lever 12 and the seat lever 13 is located at the middle position of the handle lever 12 and the seat lever 13, and is not limited to the middle position, so long as the triangle structure can be formed. The rear side of the front rod 10, the rear rod 11, the lower side of the handlebar 12 and the lower side of the seat rod 13 form a triangle structure, and the rear side of the front rod 10 and the rear rod 11 form the base of the triangle structure together, and the base is telescopic. Therefore, when folding is performed, the seat bar 13 is first turned toward the front side of the frame, the rider bar 12 and the seat bar 13, the front bar 10 and the seat bar 13, and the rear bar 11 and the rider bar 12 are turned about respective hinge points, and the rear bar 11 is moved in the direction toward the inside of the front bar 10, so that the length of the rear bar 11 extending outside the front bar 10 becomes shorter, as shown in fig. 1 and 3, in particular. When deployed, the seat bar 13 is turned in the opposite direction, and the rear bar 11 protrudes from the inside of the front bar 10.

According to the technical scheme, the front rod 10 and the rear rod 11 can be telescopic when being folded, so that the size of the frame of the baby carriage after being folded is smaller, the baby carriage is more convenient to carry, and the occupied space is smaller when being stored.

It should be noted that the handlebar 12 is used for mounting a seat of a scooter.

Further, the lower side of the seat post 13 is hinged with the rear side of the front post 10 through a second rotating shaft 6.

Further, the lower side of the handle bar 12 is hinged to the rear side of the rear bar 11 through a rotation shaft three 7.

Further, the seat bar 13 is hinged with the handle bar 12 through a first rotation shaft 5.

Further, the front lever 10, the rear lever 11, and the rider lever 12 are each provided with two sets, and are symmetrically disposed on both sides of the seat lever 13.

Further, the front end of the front rod 10 is fixedly connected with a front cross frame 2, and front wheels 21 are mounted at both ends of the front cross frame 2.

Further, the rear end of the rear rod 11 is fixedly connected with a rear cross frame 3, and rear wheels 31 are mounted at both ends of the rear cross frame 3.

Further, the handle bar 4 is movably inserted into the seat bar 13, and the handle bar 4 can stretch and retract along the length direction of the seat bar 13.

It should be noted that, when folding, the handle bar 4 may be retracted into the seat bar 13 to reduce the extension length thereof, thereby reducing the space occupied by the scooter after folding.

It should be noted that, the two front rods 10 are hinged to two sides of the seat rod 13 through the second rotating shaft 6, and the two hand rods 12 are hinged to two sides of the seat rod 13 through the first rotating shaft 5. The two rear rods 11 and the two handle rods 12 are hinged through a rotating shaft III 7, or the two rear rods 11 are fixedly arranged on the rear transverse frame 3, and the rear transverse frame 3 is hinged with the two handle rods 12 through the rotating shaft III 7.

It should be noted that, during the deployment, a limiting mechanism may be provided for limiting the rotation angle of the seat post 13 in order to control the rotation angle of the seat post 13 and in order to prevent the rear post 11 from moving out of the interior of the front post 10 entirely. The limiting mechanism can be a mechanism for directly controlling the rotation angle of the seat rod 13, for example, a limiting block is arranged between the two front rods 10, and when the seat rod 13 rotates to spread the scooter, the bottom end of the seat rod 13 contacts with the limiting block, so that the seat rod 13 can not rotate any more to excessively spread the scooter. Other means, such as limiting the angle of rotation between the handle bar 12 and the rear bar 11, may also be employed.
