DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The ratchet-driven self-propelled scooter of the invention is further described in detail with reference to the drawing hereinafter.

with reference to the drawing, a ratchet-driven self-propelled scooter, comprising a scooter body1and a transmission mechanism2set on the scooter body1;

the scooter body1comprises a scooter main body3, traveling wheels4respectively provided at the front and rear ends of the lower side of the scooter main body3and the axles5matched with the traveling wheels4;

the transmission mechanism2comprises a driving pedal6, a driving clamp7and ratchets8; the driving pedal6is arranged on the scooter main body3, the front end is installed on the scooter main body3through a supporting shaft9, and the rear end is tilted upward at an adjustable angle of 10°-45°; a torsion spring is arranged between the driving pedal and the supporting shaft to reset the pedal; the driving clamp is arranged at the lower rear end of the driving pedal, the lower part of the driving clamp is provided with a pressing arm wheel, and the bottom end is provided with a lifting arm wheel; the outer side wall of the ratchet8is provided with a ratchet arm14; the ratchet8is provided with gear teeth, and the gear teeth drive the ratchet pawl13to drive the ratchet pawl disc15to rotate; the other end of the ratchet arm14extends between the pressing arm wheel11and the lifting arm wheel12; the ratchet8is installed in cooperation with the ratchet pawl disc15, and the ratchet pawl13is installed on the pawl disc15; the ratchet pawl disc15is fixedly installed on the axle5and rotates synchronously with the axle5.

The number of traveling wheels at the front or rear ends can be1-2.

The specific embodiment of a ratchet-driven self-propelled scooter of the invention is as follows: in application, when the user steps on the driving pedal6to rotate it downward through the rotation of the supporting shaft9, the ratchet arm14is pressed down under the cooperation of the driving clamp7and the pressing arm wheel11to drive the ratchet8to rotate, thereby driving the ratchet pawl13to rotate synchronously with the axle5, which provides power to the rear traveling wheel4to make the scooter body1move forward; after releasing the pedal6, it is reset by the torsion spring10, and the ratchet arm14is reset upward under the cooperation of the driving clamp7and the lifting arm wheel12. The user can increase the driving force provided to the scooter body1by repeatedly pedaling, thereby increasing the speed of the scooter body1.

At the same time, the front part of the scooter body3can be provided with a handrail, and the rear part is provided with a brake device matched with the traveling wheel4to adapt to the safe use of children and ensure their safety.

In the description of the invention, examples of the embodiment are shown in the drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions throughout. In the embodiment, it needs to be understood that the terms “upper”, “lower”, “front”, “rear”, “left”, “right”, “inner”, “outer”, “vertical”, “circumferential”, etc. that indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing and simplifying the description, rather than indicating or implying that the pointed device or element must have a specific orientation, or be constructed and operated in a specific orientation, therefore cannot be understood as a limitation of the invention.

In the invention, unless otherwise clearly defined and limited, the terms “provide”, “connect”, “through”, “install” and other terms should be interpreted broadly; for example, it can be a fixed connection, it can be a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be an internal communication between two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the invention can be understood according to specific circumstances.

In the description of the specification, the reference terms “one embodiment”, “some embodiments”, “examples”, “specific example” or “some examples” etc. means that the specific feature, structure, material or feature described in combination with the embodiment or example is included in at least one embodiment or example of the invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the described specific features, structures, materials or features can be combined in any one or more embodiments or examples in a suitable manner.

The invention and its embodiment are described above. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the invention, and the actual structure is not limited to this. All in all, if a person of ordinary skill in the art receives its enlightenment and does not deviate from the purpose of the invention, their designed structural methods and embodiments that are similar to the technical solution without any creativity shall fall within the protection scope of the invention.
