Technical Field

The utility model relates to a scooter technical field specifically is a manpower scooter energy-conserving power unit.

Background

The manpower pedal power vehicle (bicycle/tricycle) is the earliest mechanical vehicle in the society; it is simple and convenient, healthy and environment-friendly and is deeply favored by people.

The manual power scooter converts the biological energy of a person into mechanical energy during running, so the requirement on physical strength and endurance is high due to single use of manpower in long-time running; a series of labor-saving/power-assisted rickshaws are continuously provided in the market for the problems, most of the labor-saving/power-assisted rickshaws are output by increasing the rotating speed, but the rotating speed cannot be kept unchanged while the torque is increased, so that the labor-saving effect is limited, and the market urgently needs a labor-saving energy-saving power mechanism of a manual scooter to improve the application of the rickshaws.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an energy-conserving power unit of manpower scooter aims at solving the laborsaving effect of the manpower vehicle among the prior art problem ideal inadequately.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the energy-saving power mechanism of the manual scooter comprises an equipment bracket fixedly connected with the outside and an oval guide rail groove member; the central shaft is arranged on the equipment bracket, and the axis of the central shaft is positioned at the eccentric position of the guide rail groove piece; a crank telescopic slide rail arranged on the central shaft; the crank piece can move along the crank telescopic slide rail in a single degree of freedom; and the guide pin can slide along the guide rail groove part and is connected with the crank part.

The guide rail groove piece is an elliptical ring-shaped piece with a circle of groove formed in the side face.

The telescopic slide rail of the crank is a section bar piece with a C-shaped section.

The guide pin is rotationally connected with the crank piece.

The guide rail groove piece, the crank piece and the crank telescopic slide rail are symmetrically arranged on two sides of the central shaft along the center of the central shaft, and the crank piece on the two sides is arranged at an included angle of 180 degrees.

The utility model discloses a further technical scheme:

the utility model has the advantages that: when the crank piece moves to the force application area, the distance between the end part of the crank piece far away from the central shaft and the central shaft is longer, and the torque can be better transmitted to the central shaft when force is applied to the pedal at the end part of the crank piece; when the crank piece moves to an inertia force area and a rotation area, the distance between the end part of the crank piece far away from the central shaft and the central shaft is shortened, the whole operation improves the torque of the central shaft under the condition of not increasing the movement diameter, and therefore the effect of saving more labor is achieved.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, the energy-saving power mechanism of the manual scooter comprises an equipment bracket 1 fixedly connected with the outside and an oval guide rail groove member 5; a central shaft 2 installed on the equipment bracket 1, and the axis of the central shaft 2 is positioned at the eccentric position of the guide rail groove member 5; a crank telescopic slide rail 4 arranged on the central shaft 2; the crank piece 3 can move along the crank telescopic slide rail 4 with single degree of freedom; a guide pin 6 which can slide along the guide rail groove member 5 and is connected with the crank member 3.

As can be seen from fig. 1 and 2, since the central shaft 2 is disposed at the eccentric position of the guide rail groove member 5, the motion track of the crank member 3 can be divided into a force application region, an inertia force region and a rotation region as shown in fig. 2, the guide rail groove member 5 located in the force application region has a longer distance from the central shaft 2, and the guide rail groove member 5 located in the inertia force region and the rotation region has a shorter distance from the central shaft 2, when the crank member 3 moves to the force application region, the distance from the end of the crank member 3 away from the central shaft 2 to the central shaft 2 is longer, and at this time, if a force is applied to the pedal at the end of the crank member 3, a better torque can be transmitted to the central shaft; when the crank piece 3 moves to an inertia force area and a rotation area, the distance between the end part of the crank piece 3 far away from the central shaft 2 and the central shaft 2 is shortened, the whole operation improves the torque of the central shaft under the condition of not increasing the movement diameter, and therefore the effect of saving more labor is achieved.

Specifically, the guide rail groove piece 5 is an elliptical ring-shaped piece with a circle of groove formed in the side surface, so that the guide pin 6 is clamped into the guide rail groove piece 5 and slides along the guide rail groove piece, and the guide pin 6 is prevented from being easily separated from the outer part of the guide rail groove piece 5.

Specifically, the telescopic crank sliding rail 4 is a section bar part with a C-shaped cross section, the guide pin 6 is connected with the crank part 3 in a rotating manner, the guide rail groove part 5, the crank part 3 and the telescopic crank sliding rail 4 are arranged on two sides of the central shaft 2 along the central symmetry of the central shaft 2, and the crank parts 3 on the two sides are arranged at an included angle of 180 degrees.
