Description

Wind wheel-shaped inertia wheel

Technical Field

The utility model relates to an inertia wheel structure, in particular to a windmill-shaped inertia wheel.

Background

Inertia wheels are used in many exercise devices, such as exercise bicycles, and the inertia wheels are installed on a main frame of the exercise bicycle to cooperate with a pedal assembly, so that a sporter steps on the pedal to remove the inertia wheels to increase resistance, and the existing inertia wheel structure has various structures, as shown in fig. 1-3, which is a simple internal magnetic control wheel structure a, and has the disadvantages that: its weight only distributes in certain size, if oversize can lead to the wheel body overweight, if undersize leads to the weight again insufficient, and if enough, the wheel body size can be very big, can be very limited to overall design, moreover, its moment of inertia is also not ideal for oversize.

As shown in fig. 4-6, an improved inertia wheel structure is provided, which uses the inertia wheel body B to cooperate with the friction plate C or the outer magnetic plate D, but such a structure has the following disadvantages: the linear relation can not be produced during damping adjustment in a friction mode, the external magnetic structure has various working procedures during processing, manpower and material resources are wasted, the weight is too heavy, the appearance size is too large, and the cost is very high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve prior art's above-mentioned problem, provide a wind wheel-shaped flywheel, its simple structure, light in weight, the motion is smooth and easy.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

a wind wheel-shaped inertia wheel comprises a wheel rim, wherein a group of wind blades are arranged in the wheel rim, and the wheel rim and the wind blades form the wind wheel-shaped inertia wheel.

Furthermore, the inertia wheel is made of plastic or thin iron sheet into a windmill-shaped wheel body, and the outer edge of the wheel body is coated with a layer of non-magnetic material layer.

Furthermore, a friction plate is arranged outside the inertia wheel and matched with the inertia wheel.

Furthermore, an outer magnetic sheet is arranged outside the inertia wheel and matched with the inertia wheel.

After the technical scheme is adopted, the utility model adopts the above structure, following advantage has:

1. the outer diameter of the inertia wheel can be changed according to needs, and the wind wheel-shaped structure is light in weight, and the cost can be well controlled.

2. The rim of the inertia wheel can be fully distributed on the outer ring of the wheel by adjusting the diameter and the thickness of the rim, so that the smoothness of movement is improved.

3. When the fan blade moves, the fan blade generates friction force with air, so that damping is increased, and a better movement effect can be achieved according to different movement speeds and different friction forces.

4. The structure of the friction plate or the outer magnetic plate can be matched with the outer ring to further increase or reduce the damping.

5. When in movement, the fan blades generate air convection, so that the cooling effect can be realized for sporters.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 7-10, a wind wheel-shaped inertia wheel comprises a rim 1, a set of wind blades 2 is arranged in the rim 1, and the rim 1 and the wind blades 2 form a wind wheel-shaped inertia wheel 3.

In order to further increase or decrease the damping, friction plates 4 can be arranged outside the flywheel 3 and can be matched with the flywheel.

Or, the inertia wheel 3 can be made into a windmill-shaped wheel body by plastic or thin iron sheets, the outer edge of the wheel body is coated with a layer of non-magnetic material layer, and an outer magnetic sheet 5 is arranged outside the inertia wheel to be matched with the inertia wheel.

The utility model discloses the external diameter of flywheel can change as required, and adopts the structure light in weight of draught wheel form, and the control that the cost can be fine. The rim of the inertia wheel can be fully distributed on the outer ring of the wheel by adjusting the diameter and the thickness of the rim, so that the smoothness of movement is improved. When the fan blade moves, the fan blade generates friction force with air, so that damping is increased, and a better movement effect can be achieved according to different movement speeds and different friction forces. The structure of the friction plate or the outer magnetic plate can be matched with the outer ring to further increase or reduce the damping. When in movement, the fan blades generate air convection, so that the cooling effect can be realized for sporters.
