The specific embodiment
In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
As shown in Figure 1, be the partial structure of an exercise bicycle, comprise a support 10, a crank 12 and damping unit of the present utility model.
Damping unit of the present utility model comprises a motor 14 and a controller 16.As shown in Figure 2, crank 12 can drive motor 14 rotations by a transmission mechanism 18.Transmission mechanism 18 includes the worm screw 24 of gear 20 and in the rotating shaft 22 of motor 14 that is combined on the crank 12.Motor 14 is as good as with known motor, has a shell 26, a stator 28, a rotor 30 and a brush (not shown).Stator 28 has permanent magnet, is wound with enamel-covered wire (not shown) and rotating shaft 22 on the rotor 30.Enamel-covered wire is connected to two- terminal 32,34 on the shell by brush.Two electric wires 36,38 connect the two- terminal 32,34 and the controller 16 of motor 14.Controller 16 has a switch 40 and a circuit 42.A switch 40 and a resistance R are arranged on (as shown in Figure 2) on the circuit 42.
When the user trampled crank 12, by transmission mechanism 18, the rotor 30 that can drive motor 14 rotated.This moment, the effect of motor 14 became a generator, can produce an induced electromotive force, made electric current pass to controller 16 via brush, terminal 32, electric wire 36.This electric current can flow back to motor 14 again by resistance R, electric wire 28, terminal 34, orders about rotor 30 reverse rotations.When the value of resistance R heals when big, the voltage difference that two-terminal is 32,34 is big, electric current is little, therefore produced to order about motor 14 counter-rotational strength little, the result who is caused is that to trample the resistance of crank 12 little.Otherwise when resistance R hour, the electric current that flows back to motor through oversampling circuit 42 is big, and the rotor that the orders about motor 14 30 counter-rotational strength that produced are big, and just the resistance to crank 12 is big.
So, when switch 40 switches to OFF, 42 one-tenth off states of circuit, promptly the resistance of circuit 42 is infinitely great, therefore providing the resistance of crank 12 is 0.When switch 40 switched to ON, the impedance of circuit 42 was a resistance R, therefore can produce certain resistance.
The damping unit of the utility model first embodiment only provides a certain amount of resistance, and switch 40 only provides resistance for switching or do not provide.As shown in Figure 3, a kind ofly had a selective resistance gauge of multiple amount of resistance for what the utility model second embodiment provided.The primary structure and the aforementioned structure of damping unit are as good as, mainly be made up of a motor 44 and a controller 46, (R1～R6), the resistance value of each resistance is also inequality but the circuit in the controller 46 has some parallel resistor, Option stage 48 changeable each resistance are for the size that changes resistance.Certainly, the adjustment electric resistance structure of second embodiment can simply adopt a variable resistor.
As shown in Figure 4, be the damping unit that the utility model the 3rd embodiment is provided, its damping unit with second embodiment is identical, and difference is also have the circuit that a power supply loader 50 is connected to controller 52.Power supply loader 50 has a plug 54 and a rectifier 56.Therefore, Option stage 58 can switch to each resistance (R1～R6) or power supply loader 50 (resistance that shows among the figure is R3).When Option stage switches to power supply loader 50, can import a direct current to motor 60, make motor 60 drive crank 64 and rotate by transmission mechanism 62.This moment, damping unit of the present utility model was less than effect.This device can allow the user, and particularly at some special people, for example spinal injury, patient of diabetes or other handicapped user can be driven by crank 64 and move.
As shown in Figure 5, be the resistance gauge that the utility model the 4th embodiment is provided, its damping unit with the 3rd embodiment is identical, and difference is each resistance, and (R1～R6) be the state of polyphone, the resistance value of each resistance can be identical or different.As shown in the figure, when Option stage 66 switched to position shown in the figure, this moment, the resistance value of circuit was R3+R4+R5+R6.Can utilize equally and switch Option stage 66 and change resistance crank.
Damping unit of the present utility model can be applicable on any sports equipment, for example treadmill, treadmills, elliptical machine or other relevant device.These sports equipments necessarily have a telecontrol equipment, the crank of exercise bicycle for example, the roller of treadmill and the device that confession users such as running band takes exercises by specific transmission mechanism, are connected to the motor of the present utility model just effect and the effect of attainable cost utility model with telecontrol equipment.
Characteristics of the present utility model are: utilize personnel at the kinetic energy that sports equipment moves and produces, drive Moving motor makes it produce an electric energy, passes this electric energy back this motor with the generation resistance through a circuit then again, by Change the size that resistance in this circuit can change resistance. Utilize device provided by the utility model, fully Do not need the energy that adds, can produce resistance. Therefore quite has the competitiveness on the market.
