Abstract
The utility model discloses an electromagnetic controlled equal-move training apparatus, which comprises an electromagnetic resistance device, a roller-type force application device, a restore spring device, a velocity measuring dynamo and an electrical control device. The utility model is characterized in that the electromagnetic resistance device is composed of a rotor arranged on a rotary shaft, a magnetic yoke with exciting coils and in concentric arrangement with the rotor, and magnetic powder filled in the clearance between the magnetic yoke and the rotor. The force application device and the rotor are coaxially installed, both ends of the rotary shaft are supported on bearings arranged in the magnetic yoke and the restore spring device, and the electrical control device is directly connected with the exciting coils. The utility model has the advantages of small inertia, easy start-up and restoration, no pulling force on hands and high safety.
Description
The utility model relates to the exerciser that method that a kind of usefulness overcomes resistance makes human muscle or joint be grown or strengthen, and is a kind of Electromagnetic Control isodynamic training device specifically.
Chinese patent CN86203623U discloses a kind of electromagnetism isokinetic strength training device, comprise electromagnetic resistance devices, the roll type force application apparatus, speed measuring motor and electrical control gear, electromagnetic resistance devices is by being fixed on the stator on the axle and forming with the rotor with magnetizing coil (yoke) of its concentric arrangement, be filled with the magnetic conductivity powder between stator and rotor, volume circle formula force application apparatus is that the flexibility of being fixedlyed connected with reel by a reel and an end is around Suo Zucheng, reel and rotor coaxial are installed, the one end is fixedlyed connected with rotor, the other end is provided with back-moving spring, the outer rim of rotor contacts with roller on being fixedly mounted on the speed measuring motor axle, and electrical control gear is connected between speed measuring motor and the electromagnetic resistance devices.The rotatable parts of this training aids comprise the reel of force application apparatus and the rotor with magnetizing coil (yoke) of fixedlying connected with it, rotary inertia is big, the starting or the difficulty that resets, especially still have bigger traction force to act on limbs in the end of a period that resets, be commonly called as generation " band hand " phenomenon, make the trainer feel unnatural, uncomfortable; Simultaneously because magnetizing coil is mounted in the yoke of rotation, so it with electrical control gear between be connected and must use brush and slip ring to realize, thereby reduced the security and the reliability of training aids.
It is little that the purpose of this utility model provides a kind of rotatable parts rotary inertia, is convenient to start and reset, and do not produce " band hand " phenomenon, the Electromagnetic Control isodynamic training device that reliability is high.
The utility model is achieved in that a kind of Electromagnetic Control isodynamic training device, comprise electromagnetic resistance devices, with coaxial mounted roll type force application apparatus of electromagnetic resistance devices and reseting spring device, tachometer generator by the force application apparatus driving, and be connected in electrical control gear between tachometer generator and electromagnetic resistance devices, said electromagnetic resistance devices is by the yoke with magnetizing coil that is fixedly mounted on the little inertia rotor in the rotating shaft and installs with its concentric arrangement, and be filled in magnetic conductivity powder constituent in yoke and the rotor annular gap, the reel of roll type force application apparatus and rotor coaxial are installed, the two ends of rotating shaft are bearing in respectively on the bearing set in yoke and the reseting spring device, and the output of electrical control gear directly is connected with magnetizing coil.
The reel of force application apparatus adopts light material to make in the utility model, and it and the coaxial installation of little inertia disk type rotor constitute the rotatable parts of little inertia, drive tachometer generator, so starting or reset easily when using does not produce " band hand " phenomenon, comfortable nature yet; Simultaneously since in the yoke magnetizing coil be actionless, it with do not need being connected of electrical control gear by the realization of brush and slip ring is installed, so improved security of the present utility model and reliability.
Now in conjunction with the accompanying drawings and embodiments the utility model is described specifically:
Fig. 1 is the structural representation of Electromagnetic Control isodynamic training device;
Fig. 2 is the structure and the control principle schematic diagram of electrical control gear.
As shown in Figure 1, a kind of Electromagnetic Control isodynamic training device comprises electromagnetic resistance devices 1, with electromagnetic resistance devices 1 coaxial mounted roll type force application apparatus 2 and reseting spring device 10, the tachometer generator 7 that drives by roll type force application apparatus 2, and the electrical control gear 8 that is connected in 7 of electromagnetic resistance devices 1 and tachometer generators.Electromagnetic resistance devices 1 is by fixing safety little inertia disk type rotor 5 and yoke with magnetizing coil 34 of installing with its concentric arrangement in rotating shaft 11, and is filled in magnetic 9 compositions yoke 4 and rotor 5 annular gaps in.The flexibility that a reel that roll type force application apparatus 2 is made by light material such as cast aluminium, alloy aluminum or plastics and an end are fixed on the reel is formed reel and rotor 5 coaxial installations around rope 12.The two ends of rotating shaft 11 are bearing in respectively on the bearing 13 set in yoke 4 and the reseting spring device 10.Yoke 4 and reseting spring device 10 all are fixedly mounted on (not shown) on the base.Be installed with roller 6 on the axle of tachometer generator 7, it contacts with the reel outer rim of force application apparatus 2.The output of electrical control gear 8 directly is connected with magnetizing coil 3, does not establish brush and slip ring.As shown in Figure 2, electrical control gear 8 comprises transformer 14, rectifier 15, amplifier 16 and rotating discriminator 17, and each device and connected mode thereof are known technology.
During use, external AC power supply 220V is by transformer 14, rectifier 15 is amplifier 16 power supplies, (being added with bias voltage A on the amplifier 16), pulling is around rope 12, drive reel and rotor 5 rotations, and by roller 6 drive tachometer generators 7, the signal of telecommunication of output is sent positive feedback signal into amplifier 16 and is amplified the back to the 3 input exciting curents of magnetizing coil in the Electromagnetic Control isodynamic training device 18 after rotating discriminator 17 is differentiated, produce magnetic flux, make magnetic 9 magnetization, forming magnetic force between rotor 5 and the yoke 4 connects, the size of this power is proportional to the exciting curent of input magnetizing coil 3, and it makes the reel velocity of rotation relevant with pulling around rope 12.As rotor 5 is rotated relative to yoke 4, act on around the pulling force on the rope 12 and just must overcome reluctance force between rotor 5 and the yoke 4, when having slightly around the speed of rope, pulling increases, reel rotates tachometer generator 7 output signals is increased, and the exciting curent that is fed into magnetizing coil 3 after amplifying also increases, the resistance of electromagnetic resistance devices 1 is increased, force pulling to keep constant substantially around the speed of rope 12.Loosen when rope 12, reseting spring device 10 releases energy, and makes the reel counter-rotating, tachometer generator 7 output reverse signals, rotating discriminator 17 is ended, does not have exciting curent in the coil 3, thus reseting spring device 10 can be very fast the drive reel reclaim pulled out around rope 12.Under the effect of electromagnetic resistance devices 1 and tachometer generator 7, make pulling keep constant substantially like this around rope 12 speed by electrical control gear 8 controls, make the muscle of trainee's motive position be in the peak load state constantly, and it is injury-free, and start, reset easily, do not produce " band hand ", security reliability height.
