Abstract

The utility model relates to an improved structure for a resistance generator of a magnetic control sport vehicle, and belongs to the electromechanical kind. The improved structure for the resistance generator of the magnetic control sport vehicle comprises a fixing frame whose both sides are locked with bearing caps, and the inner frame of the fixing frame is provided with a coil ring base. A magnet base whose circumference is fixedly provided with a plurality of magnets which are equidistant is arranged at axially the fixing frame, and the magnets of the magnet base space appropriate distance to the coil ring base. One end of the coil ring base extends a shaft lever which bulges out the bearing cap of the end of the coil ring base, and a flywheel is fixedly sheathed on the bulgy shaft lever. After the coil ring base which is fixedly arranged at the inner frame of the fixing frame is energized, the coil ring base can generate electromagnetic energy. When the wheel of the magnet base is turned, the magnet base which is positioned in the coil ring base can generate magnetic energy which can excite with the electromagnetic energy of the coil ring base mutually to generate electric energy. The resistance generator of the magnetic control sport vehicle has the advantages of novel structure and good heat radiation function; the resistance generator of the magnetic control sport vehicle can be effectively kept in an accurate set resistance value.

Description

The resistance generator structure-improved of magnetic control sport(s) car

Technical field

The utility model relates to electrical category, and particularly a kind of resistance generator structure-improved of magnetic control sport(s) car refers to a kind of fitness equipment that is installed in especially, can produce the resistance electric generator structure improvement of reluctance force and electric energy.

Background technology

At present, resistance electric generator structure commonly used, be one set of bell cranks and pedal to be arranged at wheel arbor both sides, back axle pivot, one belt then is set between trailing wheel and the spindle, and this front-wheel wheel frame inboard equidistantly is provided with most permanent magnets, then be provided with an electromagnet in front-wheel one side, this electromagnet top then is provided with an instrument board, and the wheel frame of this front-wheel is that aluminium is made, and axle is provided with iron core, then be wound with field coil on this iron core, this field coil is by externally fed, and this electromagnetism iron rule need not externally fed, mat trailing wheel transmission front-wheel, make field coil can produce electromagnetic energy, with the aluminium wheel frame in the running, permanent magnet produces electric energy, is positioned at the electromagnet and the instrument board power supply of a side with supply, simultaneously, impel electromagnet to produce magnetic field, and make front-wheel form appropriate resistance, to obtain the effect of motion;

Said structure because of its field coil by most permanent magnets institute around coating, though still be reserved with suitable space between field coil and the permanent magnet, but when real assembling is finished, be to add the cover enclosing cover in the open end that front-wheel is taken turns frame, this makes after the field coil energising, the heat energy that itself produced, can't dispel the heat fast and effectively, and then make and be centered around its peripheral permanent magnet and absorb the heat energy that field coil produced, so, when permanent magnet keeps the condition of high temperature for a long time, its magnetic can obviously weaken, causing influencing the resistance that the resistance generator produced can't accurately control, and the Resistance Value after setting can be in a kind of unsettled quick condition, need be improved.

The utility model content

According to the purpose of this utility model, the shortcoming that exists at above-mentioned resistance electric generator structure commonly used, a kind of resistance generator structure-improved of magnetic control sport(s) car is provided, it comprises: a fixed frame two side chains are provided with bearing cap, its inside casing is equiped with a coil ring seat, one periphery equidistantly is installed with the magnetic receiver of most magnet and is located at the axial of fixed frame, and the magnet of this magnetic receiver is with the coil ring seat suitable distance to be arranged at interval, and the one end is extended with the bearing cap that an axostylus axostyle protrudes from this end; One flywheel is fixed on the axostylus axostyle of protrusion; After the coil ring seat energising that is installed in the fixed frame inside casing, this coil ring seat can produce electromagnetic energy, and magnetic receiver is taken turns when rotating, the magnetic receiver of position in the coil ring seat can produce a kind of magnetic energy, it is to excite the generation electric energy mutually with the electromagnetic energy of coil ring seat, so that provide other power consumptions less, and the device that is installed on the same fitness equipment uses; Simultaneously, this ring permanent magnet of being located at the magnetic receiver periphery can produce a kind of reluctance force with the coil of coil ring seat.

Advantage of the present utility model is: novel structure, and can effectively remain on one and accurately set Resistance Value, heat sinking function is good.

Fig. 3 is the utility model cross-sectional schematic.

Embodiment:

To shown in the accompanying drawing 3, the utility model comprises as accompanying drawing 1:

10 liang of side chains of one fixed frame are provided with bearing cap 11, and the inside casing of this fixed frame 10 is equiped with a coil ring seat 20 that forms with coil 21 windings, and this coil ring seat 20 is by outside supply power; Wherein, this bearing cap 11 is provided with axis hole 112;

One periphery equidistantly is installed with the magnetic receiver 30 of most magnet 31, the inner axis that this magnetic receiver 30 is installed in fixed frame 10 to, its central shaft 32 is set in the axis hole 112 of two bearings lid 11, and the axostylus axostyle 32 of an end protrudes out the axis hole 112 of a bearing cap 11, is nested with so that flywheel 40 to be provided; Wherein, be separated with suitable distance between the magnet 31 of the magnetic receiver 30 that installing is finished and coil ring seat 20 relative inner, be provided with bearing 33, when magnetic receiver 30 is rotated, be unlikely affecting bearing cap 11 and coil holder 20 motions and be situated between between the axis hole of axostylus axostyle 32 and bearing cap 11;

One flywheel 40 is fixed in axostylus axostyle 32 ends of protrusion, it axially is arranged with a belt pulley 41, and the position is equiped with a bearing 411 between belt pulley 41 and axostylus axostyle 21, be respectively equipped with a unilateral bearing 42 and a ball bearing 43 between flywheel 40 and the belt pulley 41, make belt pulley 41 only can affect flywheel 40 to make one-directional rotation;

Form by said structure, after giving 20 energisings of coil ring seat, this coil ring seat 20 can produce electromagnetic energy, and magnetic receiver 30 is when rotating, the position can produce a kind of magnetic energy at the magnetic receiver 30 of coil ring seat 20 inner rings, it can excite the generation electric energy mutually with the electromagnetic energy of coil ring seat 20, so that provide the less and device that be installed on the same fitness equipment of other power consumptions to use; Simultaneously, this ring is located at permanent magnet 31 meetings of magnetic receiver 30 side faces and a kind of reluctance force of coil 21 generations of coil ring seat 20; The utility model is installed in coil ring seat 20 inside casing of fixed frame, form one with it, after mainly providing the energising of coil ring seat, the heat energy that is produced can be passed to fixed frame fast, and the bearing cap of both sides, by the peripheral good ventilation of fixed frame, it is good to arrive heat sinking function, and make and be installed in inner permanent magnet, be unlikely overheated high temperature and its magnetic is weakened.
