AI Technical Summary

Technical Problem

Existing adjustable foot pedal devices suffer from problems such as large space occupation, uneven lifting, excessive power requirements, jamming, and uneven pedaling force when space is limited.

Method used

It adopts a sliding seat and guide rod structure, combined with a push rod and tension spring balancing mechanism. The pedal is raised and lowered by a lockable gas spring and pull cable. The combined torque of the push rod and tension spring balances the pedal weight, reducing the size and force requirements of the power components. The tension spring length is adjusted by adjusting bolts to ensure smooth movement.

Benefits of technology

It enables smooth lifting and lowering in small spaces, reduces the size and force requirements of power components, solves the problems of jamming and uneven pedaling force, and improves the comfort and safety of operation.

Abstract

This invention belongs to the technical field of foot pedal devices and discloses a lifting foot pedal, including a pedal, a base, a lifting mechanism, a power mechanism, and a balancing mechanism. The lifting mechanism includes a sliding seat and a guide rod. The sliding seat is slidably mounted on the guide rod, and the guide rod is mounted on the base. The power mechanism includes a lockable gas spring. The balancing mechanism includes a push rod and a tension spring. One end of the push rod is connected to the sliding seat, and the other end is a sliding end mounted on the base. One end of the tension spring is connected to the base and located between the sliding end and the lifting mechanism, and the other end is connected to the sliding end on the push rod. One end of the pedal is movably mounted on the base, and the other end is connected to the sliding seat. With the above configuration, the pedal can move up and down along the guide rod with the sliding seat. One end of the lockable gas spring is installed on the sliding seat, while the other end can be obliquely mounted on the mounting base, reducing the installation height, facilitating reasonable structural arrangement, and solving the problem of limited space.
