An intelligent counterweight fitness device

Abstract

The invention discloses intelligent counter weight fitness equipment. The equipment comprises a barbell rod, a spring movement module, a motor movement module, a connecting device, a force measurementfeedback module, a speed measurement feedback module and a control center module, wherein the connecting device connects the barbell rod with the force measurement feedback module, the force measurement feedback module with the spring movement module, and the spring movement module with the motor movement module; the force measurement feedback module is used for measuring upper tensile force of the connecting device; the speed measurement feedback module is used for measuring speed of the connecting device; and the speed measurement feedback module, the force measurement feedback module and the motor movement module are electrically connected with the control center module capable of being controlled wirelessly. The intelligent counter weight fitness equipment eliminates the inconvenienceof assembling and disassembling barbell pieces, achieves non-polar counter weight, reduces the weight and volume which are needed by the counter weight, and can ensure the safety of body builders.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an intelligent weight fitness equipment. Background technique [0002] With the continuous improvement of living standards, people pay more and more attention to their own health, and more and more people start to participate in fitness training. The types of fitness training are mainly divided into two types, one is aerobic training such as running and cycling, and the other is anaerobic training such as bench press and squat. With the development of science and technology, almost all aerobic fitness training equipment has realized intelligence and automation, such as treadmills, climbing machines, elliptical machines, etc., which can intelligently adjust the size of resistance and record fitness data. But all anaerobic exercise fitness equipments still adopt the method of weight counterweight to provide resistance, and do not realize the intelligent selection and con...

AI Technical Summary

Problems solved by technology

Its main defects are: 1. It is recorded in the document that the rotating shaft of the motor is fixedly connected with the rotating shaft of the rotating mechanism, and the motor applies resistance to the rotation of the rotating shaft of the rotating mechanism through its own rotational torque , that is, the rotation of the motor and the rotation mechanism are fixedly connected, and the counterweight system provides the required counterweight through the direct output torque of the motor; this method of controlling the motor is unreasonable and inconvenient to realize in actual design and production; 2. The fitness equipment counterweight system of this patent is to provide intelligent counterweights for rowing machines, and cannot provide counterweights for barbell bars; 3. This patent does not propose the concept of safety protection for bodybuilders when they are exhausted. Exhaustion is a very dangerous state. For example, when exhaustion occurs when performing actions such as bench press or squat, the bodybuilder may be life-threatening in severe cases, and may sprain joints or muscles in light cases, causing unnecessary losses.

The device provided by CN101007205A does not have a speed measurement feedback module, so the device can only judge whether the motion state of the resistance loading end is stalled by judging whether the motion speed of the current motor is abnormal

Since the movement speed of the motor is a controlled quantity, it is not strictly equal to the movement speed of the resistance loading end, so using this index to judge the stall has a great risk, which is not convenient for the realization of the safety of the fitness equipment
