Description

Magnetic bike

Technical field

The utility model relates to sports goods field, specifically a kind of magnetic bike.

Background technology

Utilize various sports apparatus that people can be helped to reach the effect of taking exercises, magnetic bike is exactly a kind of, magnetic bike is called cycle ergometer in sports science field, it is divided into vertical type and backrest-type exercycle two kinds, the mode of the outdoor cycling of main analog, accelerate metabolism with suitable intensity, strengthen the function of heart, lung and blood vessel, to improve the object of human body constitution.

The vehicle frame of the magnetic bike of all styles of is made by various tubular bracket, because tubular bracket has the light and handy feature of rugged construction, be widely used in various exercycle, there is square tube, pipe, and shape tube etc., by welding, riveted joint, the bolt mode such as to fix is assembled into the body construction of bicycle, this architecture basics is installed some moving components, in use, because moving component conduction kinetic energy, the each parts of car body are made to have friction and clash into, exercycle can produce vibrations and noise, its tubular bracket is hollow-core construction, itself can produce noise, also therefore noise can be amplified, affect user's mood, also affect surrounding environment, affect train on.

The structure of so-called magnetic control is: as shown in Figure 6, and magnetic control wheel 18 is made up of the coated conductive layer 21 (aluminium sheet or copper coin) of cast iron flywheel 22, flywheel rim and magnet assemblies 23.Magnet flywheel provides inertia, and plays magnetic conductor effect, forms magnetic field.The aluminium sheet of conductive layer or copper coin can by the rotations of flywheel, and cutting magnetic field produces magnetic control resistance.In addition, the existing exercycle cushion face in market is comparatively hard, and common seat cushion mostly is sponge and fills, and seat cushion elasticity is inadequate, and seat cushion support dynamics is inadequate, and people are when using these common seat cushions, and long-time exercise more easily makes buttocks produce numb and sense of discomfort.Simultaneously, when we find that user rides fast, forward lean, buttocks can depart from seat cushion with health equally, buttocks can not fully be fitted with seat cushion, and therefore common seat cushion can not good support hip curve, can not well bear a heavy burden by support health, people, when long-time these seat cushions of use, more easily produce fatigue.Simultaneously, common vehicle seat front end is without the groove of release pressure, easily cause compressing and the numbness of human body perineal region, such seat cushion uses for a long time and all has a certain impact to the ischium genital area blood circulation of human body and sexuality, and common seat cushion is stuffy without groove, airtight when seat cushion and skin contact, easily sultry, not easily temper use for a long time.Secondly, do not have zone of transition when both sides, common seat cushion front end are narrowed, user easily rubs when taking exercise thigh both sides.

Summary of the invention

The purpose of this utility model is to provide a kind of magnetic bike, simplifies vehicle body frame, reduces parts binding site, reduces noise vehicle seat and more meets ergonomics, overcome the deficiency of above-mentioned technology.

Magnetic bike of the present utility model, comprise body frame, the sub-display instrument of LED electrical, vehicle seat, box body, chassis, it is characterized in that described box body is mounted to entirety by inlaying bottom chassis and body frame, large flywheel and magnet frame is supported by fly frame in box body, oblique frame supports bent axle, and coaxial mounted steamboat, pedal, fly frame, oblique frame is fixed on rectangular slab, and embed in seat at the bottom of body frame by chassis, vehicle seat adjustable pipe inserts in oblique frame, the top of car adjustable pipe connects vehicle seat, wire is had to be communicated with fractional motor and magnet frame in the sub-display instrument of LED electrical and chassis in body frame armstand, two pieces box body as shell is entrenched on below-seat, chassis relatively.

Vehicle seat shape: vehicle seat is sewed up by middle part and both sides fin, there is concave curved surface after lordosis centre, and recess has elongated hole, is combined with both sides fin at the dual-side of middle recess, and prominent curved surface is stuck up in formation both sides, rear portion.

Design of the present utility model, not changing on conventional magnetron exercycle operation principle and in-built basis, is combined into one the vehicle frame of formula to magnetic bike body frame and box body two parts.Internal moving parts and structure still adopt magnet and rotary flyweights, belt, move with foot-operated bent axle, the sub-display instrument external power supply of LED electrical, at rack bore connection circuit, control fractional motor, fractional motor passes on the distance between instruction regulation and control rotary flyweights and magnetic control group again, by the change of distance, the resistance between rotary flyweights and magnetic control group is changed, thus regulates and controls drag size.Because Belt Length is fixed, there is certain tensile force, by regulating the distance of rotary flyweights and magnetic control group to regulate the frictional force size between belt and wheel to regulate the drag size of magnetic bike, to arrange different resistance sections, regulating dynamics of riding.The design that seat cushion front end is slowly narrowed from rear portion, a buffer area of narrowing is defined in seat cushion front end, distinguish the design that common vehicle seat front end does not have transition, ensure to ride for a long time the thigh both sides that do not rub, in Fig. 4, each figure illustrates the design of the oval mellow and full projection in seat cushion rear end, splendid elasticity, intact laminating hip curve, adds buttocks lifting surface area and makes motion lighter.Be for common seat cushion can not with the significant improvement of intact this problem of laminating of buttocks.Oval-shaped groove design ventilative in the middle of seat cushion, compares the pressure that common vehicle seat decreases prostatic top, can avoid oppressing key position.Meanwhile, for seat cushion provides aerodynamics contact, reduce feeling of oppression and heat, keep buttocks dry and comfortable for a long time.
