Damping device for fitness equipment

The present invention relates to a damping device, and more particularly to a damping device suitable for use in fitness equipment.

In recent years, with the prevalence of sports, there are many sports and fitness equipment for indoor use, such as treadmills, weightlifting machines, indoor bicycles, rowing machines, etc., so that users can be indoors without being affected by the weather. work out.

Taking the rowing exercise machine as an example, the early main structural design is to provide a slide rail on a base, and a slidable seat cushion group is slid on the slide rail, and one end of the base is provided with a pedal for the user to step on. a pedal group, and a rocker group on the pedestal on both sides of the seat cushion group for the user to perform a rowing motion, thereby allowing the user to hold the pedal group with both feet and simultaneously holding the rocker group with both hands and applying The rowing force is applied to the front and rear push and pull, and the movable seat cushion group slides back and forth on the sliding rail. It mainly aims to exercise the muscles of the hands, legs, chest, waist and back by simulating the action of rowing.

Later, in order to improve the function of the rowing exercise machine, the relevant manufacturers proposed various improved designs. For example, the invention of the Republic of China Announcement No. I249416 "Magnetic Control Wheel Blade Structure Improvement" is an example. The case is mainly on a fitness rack. The pivoting device is combined with a reeling wheel and a magnetron wheel, and the reeling wheel is provided with a one-way bearing, so as to have a wheel-shaped member with a one-way turning and rolling function, and a belt is provided on the axle. a winding portion that is wound and fixed at one end, and a belt portion that is disposed adjacent to the winding portion, the belt portion is sleeved at one end of a belt, and the other end of the belt is sleeved on the magnetic wheel Corresponding position. At the other end of the webbing, a grip for the user to hold is attached. In addition, a wind impeller is fixed to the side of the wheel of the magnetron wheel. The path of the fan blade rotating by the wind impeller and the circumferential surface of the magnet wheel are mutually offset, so that the wind impeller rotates with the magnetron wheel, combines the centrifugal force of the swing and the principle of high and low pressure, and cooperates with the fan. The air intake space at the bottom end of the leaf is designed to form a guiding airflow structure to conform to the principle of fluid mechanics, so as to effectively generate wind resistance, thereby increasing the damping effect of the magnetron wheel and providing a resistance effect when the user performs fitness.

However, the improved design of the above-mentioned magnetron wheel blade structure is that the user grips and pushes the grip bar back and forth, and the webbing is driven to rotate the reeling wheel, and then the magnetic wheel and the wind wheel are synchronously rotated through the belt. Since the transmission belt drives the magnetron wheel and the wind impeller to rotate synchronously in a single transmission manner, the generated resistance is limited, and the training effect is also limited.

Therefore, one of the purposes of this creation is to provide a counterweight averaging and to provide uniform and adjustable resistance, which can meet the training and fitness needs of users of different physical strengths, so that the user's exercise training is more accurate.

The hollow housing 911 of 91 rotates such that the magnetic sheets 913 are rotationally displaced relative to the coil assemblies 914 as the hollow housing 911 is rotated, causing the coil assemblies 914 to generate an induced current due to changes in magnetic flux. The power is generated, and then the power can be supplied to the human-machine interface unit 3 or the display screen 31 (see the second figure), and the power storage unit 5 can be charged to supply the power required for the motor 4 to operate.

Referring to the eighth embodiment, a second embodiment of the damper device of the present invention is substantially the same as the first embodiment, except that the adjustable resistance member 9 omits the magnetic member 919 (see FIG. 7), whereby the frictional effect existing between the outer surfaces of the substrate 9161 when they are in direct contact with the inner surface of the fixing ring 912 is used to provide a damping effect.

In summary, the damper device of the present invention is designed such that the transmission wheel 62 of the transmission unit 6 is disposed at the center of the linkage shaft 61, and the first rotation wheel 63 and the second rotation wheel 64 are respectively The resistance fan 81 and the adjustable resistance member 9 of the resistance unit 8 are respectively disposed on the outer side of the first rotation wheel 63 and the second side of the first rotation wheel 63.
