Technical Field

The invention belongs to the technical field of mechanical products, and particularly relates to types of scooters.

Background

The scooter is the follow-up tradition scooter the novel product form of slide motion again, it is simple laborsaving sports machinery, present child is more stubborn, can often slide the scooter to rugged section, even if the even time flat road section, unevenness's place can also appear in the inevitable, current scooter includes handlebar assembly, the stand, the front wheel, the connecting axle, rear wheel and base, wherein the cushioning property of base is not good, when sliding to above-mentioned rugged section or pit department, the base can produce very big vibrations, make the unable deformation of scooter and absorb jolt in the driving process, when road surface condition is not good, cause user's too early fatigue easily, influence safe driving and comfort level.

Disclosure of Invention

The technical problem mainly solved by the invention is to provide child scooters with damping function, vibration force is reduced through the design of a novel buffering and damping structure, jolts in the driving process can be absorbed by a base of the scooter, and the driving safety and comfort are improved.

In order to solve the technical problems, technical schemes adopted by the invention are that children's scooters with a damping function are provided, each scooter comprises a handlebar assembly, an upright post, a front wheel, a connecting shaft, a rear wheel and a base, wherein the handlebar assembly is installed at the upper end of the upright post, the base is installed at the lower end of the upright post, the connecting shaft is installed at the front end of the base, the front wheel is respectively installed at two ends of the connecting shaft, and the rear wheel is installed at the rear end of the base;

the base is of a double-layer structure comprising an upper base and a lower base, a plurality of damping buffers and at least two supporting buffers are uniformly arranged between the upper base and the lower base at intervals, each damping buffer comprises upper fixing columns, at least four lower fixing columns and extension springs with the same number as the lower fixing columns, all the lower fixing columns are centered on the upper fixing columns and are uniformly distributed along the circumferential direction of the upper fixing columns, and each supporting buffer is fixed on the upper base at the upper end and fixed on the lower base at the lower end;
