A mechanical device for automatically adjusting torque

Abstract

The invention relates to a mechanical device capable of automatic torque adjustment. The device comprises a pressure sensing plate, wherein a supporting pillar is disposed on the top of the pressure sensing plate; a pressure sensor and a microprocessor are disposed on the supporting pillar; the top part of the supporting pillar is connected to a main arm by a rotation shaft; a small telescopic motor is disposed in an inner chamber of the main arm; an electric telescopic rod is connected to one side of the small telescopic motor; the electric telescopic rod passes through the main arm; a hanging rope is connected to one side of the electric telescopic rod; a balance weight block is connected to the bottom of the hanging rope; and a supporting rod is firmly connected to one side of the main arm. The pressure sensor and the microprocessor are disposed, so that the pressure sensing plate can be used to sense pressure changing on a seat; the electric telescopic rod with the balance weight block hung on one side is disposed; the microprocessor has a setting value; the pressure sensing plate feeds back force changing to the microprocessor; and according to the force changing, the microprocessor controls the small telescopic motor to drive the electric telescopic rod, so that the electric telescopic rod can be stretched and retracted.

Description

technical field [0001] The invention relates to a mechanical device for automatically adjusting torque, which belongs to the field of fitness equipment. Background technique [0002] In physics, the action force makes the object rotate around the rotation axis and the fulcrum, which is called torque (torque). The torque can make the object change the rotational motion. It will involve torque. In mechanical design, the influence of torque is immeasurable, so designers must strictly pay attention to torque problems. [0003] The positioning of the torque is usually the distance multiplied by the force. Mathematically, the order of Newton and meter can be exchanged. The International Weight Monitoring Bureau strictly stipulates that the ultimate goal of mechanical design is to use various existing conditions (calculation methods, materials, Theoretical knowledge and processing ability, etc.), to design the best machinery, or called optimal design, mechanical design usually nee...
