Pedal or seat flip torque balancing combination mechanism

Abstract

This invention relates to the field of pedal or seat folding technology, and discloses a pedal or seat flipping torque balancing assembly mechanism, comprising a spring assembly, an electric telescopic mechanism, a fixed bracket assembly, a pedal assembly, and a pedal pivot. The pedal assembly rotates around the pedal pivot. One end of the spring assembly is fixed to the fixed bracket assembly, and the other end is fixed to the pedal assembly. One end of the electric telescopic mechanism is fixed to the fixed bracket assembly, and the other end is fixed to the pedal assembly. When the pedal is retracted, the spring is extended to its maximum length, at which point the spring force is minimal; as the pedal is flattened, the spring force gradually increases, and the torque of the spring force around the pivot can balance most of the torque of the pedal's weight around the pivot. During the retraction and flattening of the pedal, since the spring force torque can balance most of the pedal's weight torque, a more compact electric telescopic mechanism can be selected. The electric telescopic mechanism occupies less space and has a lower cost, while simultaneously meeting the requirements of economy and space utilization.

Description

Technical Field

[0001] This invention relates to a pedal or seat flipping torque balancing combination mechanism. Background Technology

[0002] In my country, the lack of elevators in multi-story residential buildings constructed in the 1980s and 90s has made vertical transportation a critical issue for urban residents. Over the past 20 years, a large number of self-built houses have been constructed in rural China, typically two stories or more, even reaching five stories. These houses also generally lack elevators, creating a pressing need for low-cost transportation for both people and goods. However, installing elevators in these multi-story or self-built houses faces a series of challenges, including complex approval procedures, difficulties in obtaining land use permits for shafts, high renovation costs, long construction periods, uneven benefits for lower and higher-floor residents leading to disagreements, impacts on lighting and ventilation for lower-floor residents, and even conflicts with existing building codes. These issues make implementation difficult.

[0003] A more reasonable existing solution is to install multiple elevators close to the walls or railings in the stairwell, solving the problem of residents' difficulty in going up and down stairs without affecting the normal use of the stairwell. For example, the stairwell elevator and its drive mechanism disclosed in patent document No. 201610278716.7. The pedal tilting mechanism of this patent is relatively complex and thick, occupying stairwell space. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a pedal or seat flipping torque balancing combination mechanism, comprising a fixed bracket assembly (1), an electric telescopic mechanism (2), a spring assembly (3), a pedal assembly (4), and a pedal pivot (5). The pedal assembly (4) rotates around the pedal pivot (5). One end of the spring assembly (3) is fixed to the fixed bracket assembly (1), and the other end is fixed to the pedal assembly (4). One end of the electric telescopic mechanism (2) is fixed to the fixed bracket assembly (1), and the other end is fixed to the pedal assembly (4). When the pedal is retracted, the spring is extended to its maximum length, at which point the spring force is at its minimum. As the pedal is flattened, the spring force gradually increases, and the spring force torque around the pivot can balance most of the pedal gravity torque around the pivot. During the retraction and flattening of the pedal, since the spring force torque can balance most of the pedal gravity torque, a smaller electric telescopic mechanism (2) can be selected. The electric telescopic mechanism (2) occupies less space and has a lower cost, while simultaneously meeting the requirements of economy and space utilization.
