Description
Technical field
The present invention relates to a kind of fitness equipment technology, especially a kind of physical-strength-type fitness facility sources of resistance.
Background technique
How much fitness equipment is often divided into single function and integrated multi two major classes with training function, and there are commonly row the boat
Device, bodybuilder, fitness climber, treadmill, beauty belt massage etc..Strength fitness equipment, also referred to as anaerobic health and fitness facilities are to temper skeletal muscle
Speed, strength, explosive force and bodybuilding are leading common exercising device, it is that resistance of motion size is adjusted by counterweight, one
Well matched heavy weight is invariable (such as 5kg, 10kg, 25kg or more), can only change movement by increase and decrease clump weight
Resistance (generally 5Kg).
Current strength fitness equipment adjusts fiber crops by way of increasing and decreasing clump weight when needing to change different training resistances
It is tired, especially more people's uses when need frequently to be adjusted, heavy workload is not smart enough.
205198795 U of Chinese patent CN discloses the counterweight load system on a kind of fitness equipment, including fitness equipment branch
Frame, pulling force rope, motor, motor drive module and motor control unit；The motor is mounted on body-building instrument support and rotatable, institute
It states pulling force rope to be wrapped on motor, one end is connected with the rotor of motor, the strength driving mechanism on the other end and fitness equipment
Connection；The strength driving mechanism is used to move motor rotation by pulling force strap to generate pulling force, the motor control unit
The load force that motor opposite direction rotates and keeps its generation opposite with pulling force is controlled by motor drive module.The patent uses one
Motor is directly wound with pulling force rope, and since motor inertia is larger, plus a small opposite force especially on motor, it is just generated
Small strength, motor can be operated to the opposite direction of strength when firmly, and the inertia of generation, small opposite force cannot allow motor to stop
Only, generate strength gap causes strength to impact to person taking exercise, that is, uses a motor, when using different forces, it has not been convenient to
Control.
It is dynamic that 105882382 A of Chinese patent application CN discloses a kind of double clutch bi-motors mixing with retarder module
Power assembly, engine, preceding single disc clutch, first motor, rear single disc clutch, the second motor, subtract elastic shock attenuation connector
Fast device module is coaxially sequentially connected；Retarder module is connect with driving axis；Entire car controller respectively with accumulation power supply, first
Electric machine controller, the connection of the second electric machine controller, first motor controller are also connect with first motor, accumulation power supply respectively, the
Two electric machine controllers are also connect with the second motor, accumulation power supply respectively.Added although being disclosed in the patent application using bi-motor
Double clutch construction, but the power assembly may be only available for new-energy automobile field, can not be suitable for field of exercise equipment.
