Description
Technical field
The utility model relates to body-building apparatus; Relate in particular to and a kind of generator is installed in the flywheel outside; Recently produce high-power with rev up; And with its electric current of giving birth to supply to be defeated by solenoid, form a reverse resistance so that flywheel is rotated, the body-building apparatus and the Facility for resuming health that reach movement effects are used the self power generation drag devices.
Background technology
The early stage body-building apparatus of the U.S. is directly to use as resistance system with electric generators for automobile, but because of it is not inconsistent the characteristic demand of body-building apparatus, so produce following improvement successively.
First item is the resistance system of pure generator forms; Shown in Figure 1A, Figure 1B, on an axle center 11, wear inertial flywheel 12 and iron core 14, be arranged with power coil 15 on 14 circumference unshakable in one's determination; When permanent unshakable in one's determination 13 of inertial flywheel 12 and inner peripheral thereof rotates, promptly form a generator 10 kenels.This type patent is seen in case before United States Patent (USP) No. 4775145, No. 5558624, No. 5236069 etc., only looks into, and this kind form has following inevitably shortcoming:
1,, when the needs resistance,, and produces the effect of braking with original generator short circuit because of its resistance source is the power reverse reversal connection with generator.In the design in order to increase brake force, how with strengthen rotating speed recently in response to, but so the practice will increase the difficulty in the manufacturing.
2, the vibrations and the noise that produce owing to the contrary multiple harmonic that connects of the 1st power supply can be more obvious under high rotating speed.
3, the power some that generator produced must be consumed, and therefore need install a big resistance additional to consume its unnecessary power, causes its cost higher, and efficient is lower.
Second section is a kind of mixed type generator, and installs the design of a solenoid 16 and unshakable in one's determination 17 additional in the outside of inertial flywheel, and its pattern is shown in Fig. 2 A, Fig. 2 B.This type structure is seen in No. 6084325 patent in the U.S..Its power that pure generator is unnecessary is used for producing brake force, to reach the desired resistance of body-building apparatus and Facility for resuming health, though it improves expensive, the inefficient shortcoming of pure generator, but still has disadvantage:
1, structure is fixed, because solenoid 16 and unshakable in one's determination 17 keeps identical air gaps just to have higher characteristic to show with 12 palpuses of inertial flywheel, so can't be with client's the demands of different random change of the appearance and size of generator.
2, because generator core 14 is two autonomous systems of separating with solenoid unshakable in one's determination 17, so cost is higher.
3, solenoid 16 causes its volume bigger for being installed in the independent individual outside the inertial flywheel 12, is unfavorable for the global design of vehicle frame.
The threeth is a kind of mixed type generator, and installs the design of solenoid 16 and unshakable in one's determination 17 additional in the inboard of inertial flywheel, and its pattern is shown in Fig. 3 A, Fig. 3 B.This type structure is seen in No. 7732961 patent in the U.S.; Though this pattern has been improved the most disappearance of the second style formula; But it is the same with aforementioned two kinds of patterns; Its generator all is the big belt pulley via body-building apparatus or Facility for resuming health, adopts one section kind of drive and drives its small belt pulley, and its rotating ratio generally is no more than 1: 20; Therefore the rotating speed of generator is on the low side relatively.Press, the efficient of generator and its rotating speed have substantial connection, and when the rotating speed height of generator, then power output is high, and the rotating speed of generator is low, and then power output is low; Because its rotating speed of generator of aforementioned three kinds of patterns is restricted, therefore do not bring into play its due efficient.
