A double-lever series structure that allows the transmission wheel to rotate continuously

Abstract

This invention relates to a lever-multiplying structure for use in mechanical transmission systems, specifically a double-lever series mechanism that enables the transmission wheel to maintain continuous rotation. The structure mainly consists of an upper lever, a lower lever, and a double-scissor compression assembly. The force application point of the lower lever is connected to the fulcrum of the upper lever. Through the series connection of the upper and lower levers and the linkage of the compression assembly, when an external force is applied to the upper lever, it simultaneously drives the lower lever to generate a force-multiplying effect, and the transmission wheel rotates continuously through a crank and drive shaft. This invention can transform intermittent reciprocating force into stable and continuous rotational motion, achieving high-efficiency energy conversion. Furthermore, due to the parallel vertical movement path of the levers, the lever length can be extended as needed to increase the output torque. This structure not only improves mechanical efficiency but also possesses good expandability and practicality, making it suitable for bicycles, fitness equipment, and various mechanical transmission devices.

Claims

1. A double-lever series structure that allows a transmission wheel to rotate continuously, characterized in that: it comprises a double-scissor compression assembly, an upper lever, and a lower lever; wherein, The double-shear compression assembly has a cross-link structure that can move up and down. The upper lever is located above the compression assembly and has a fulcrum, a resistance point, and a force application point. The lower lever is located below the compression assembly, and its force application point is connected to the fulcrum of the upper lever. When an external force is applied to the force application point of the upper lever, the external force is transmitted to the lower lever through the fulcrum of the upper lever, so that the upper and lower levers produce a series force multiplication effect, and the transmission wheel is continuously rotated by the transmission shaft.

2. The double lever series structure as described in claim 1, wherein the direction of movement of the upper lever is parallel to the direction of movement of the double scissor compression assembly, so as to ensure the stability of the lever movement and the efficiency of torque transmission.

3. The double lever series structure as described in claim 1, wherein the lengths of the upper and lower levers can be extended according to application requirements to adjust the output torque.

4. The double lever series structure as described in claim 1 is applicable to human-powered devices, including bicycles, fitness equipment, etc.

5. The double lever series structure as described in claim 1 is applicable to mechanical drive devices, including electric vehicles, generators and other mechanical systems requiring continuous transmission.
