Fig. 1 is a schematic structural diagram of an inertia providing apparatus for a rowing machine according to the present embodiment, and as shown in fig. 1, the inertia providing apparatus 100 includes a motor 110 and a supercapacitor module 120.
In this embodiment, the rotating device is the motor 110, and the rotor shaft of the motor 110 rotates and converts the energy output by the user using the rowing machine into electric energy, i.e. has a power generation module. The electric energy device is a super capacitor module 120, and the super capacitor module 120 is formed by connecting a plurality of super capacitors, and the super capacitor module 120 is provided with a charging module which can charge and store electric energy.
The rotor shaft of the motor 110 is used for being connected with a transmission shaft of the rowing machine 100, and the super capacitor module 120 is electrically connected with the motor 110.
When in use, a user drives the transmission shaft of the rowing machine 200 to rotate, and the transmission shaft of the rowing machine 200 drives the motor 110 to rotate and converts the energy output by the user through the rowing machine into electric energy.
When the motor 110 rotates in an accelerating way, the output voltage of the motor 110 is greater than the voltage of the super capacitor module 120, the super capacitor module 120 is charged in a charging process to prevent the motor 110 from rotating in an accelerating way, and further prevent the transmission shaft of the rowing machine from rotating in an accelerating way, so that rowing inertia is provided for the rowing machine, and a user obtains real rowing feeling.
The super capacitor module 120 can also be replaced by a super capacitor module 120 such as a rechargeable battery, and the super capacitor module 120 is a single super capacitor or is formed by connecting a plurality of super capacitors.

In view of the above advantages of the super capacitor, as a preferred embodiment, in this embodiment, the super capacitor module 120 is used as the electrical energy device, and the super capacitor module 120 is formed by connecting 3 super capacitors in series.
When the practical racing yacht is rowed, the racing yacht weight is about 1/10 of the human body weight, and the racing yacht speed is about 5 m/s. Taking a rowing weight (sum of the weight of the user and the weight of the racing boat) of 80 kg as an example, the kinetic energy E=1/2 mv is generated at a rowing speed of 5m/s 2 =1000 joules (where v is the rowing speed in meters per second; m is rowing weight in kilograms).
The parameters of the super capacitor commonly used in the market are: rated voltage u=16v, capacitance c=16.6f, energy storage capacity q=1/2 CU of supercapacitor under this parameter 2 =2124 joules > 1000 joules. It can be seen that from an energy point of view, the super-capacitor under this parameter provides sufficient inertia, whereas the weight of the super-capacitor under this parameter is only 141g. Even the super capacitor module 120 with rated voltage u=16v, capacitance c=66F and energy storage capacity of 8448 joules has a weight of only 450g.
As shown in fig. 1, in the present embodiment, the motor 110 is a brushless motor 111, and the brushless motor 111 is connected to a rectifier 130. Fig. 4 is a torque density meter of the motor 110 in the prior art, according to fig. 4, the brushless motor 111 in this embodiment adopts the neodymium iron boron permanent magnet, the torque easily reaches 8.9Nm, the torque requirement on the structure of the current middle-end rowing machine is completely satisfied, and the weight of the motor 110 is within 3 kg.
Therefore, the sum of the weights of the motor 110 and the supercapacitor module 120 in this embodiment is much smaller than the weight of the mechanical flywheel in the prior art (the weight of the flywheel in the prior art is all above 5 kg), and the weight reduction is more than 40% for the inertia providing component itself, if more inertia is needed to be provided, the weight reduction effect is better.
In summary, the total weight of the brushless motor 111 and the supercapacitor used in the inertia providing apparatus according to the embodiment of the present application is about 3 kg. Under the same rowing condition (rowing weight and rowing speed), compared with the mechanical flywheel in the prior art, the inertia providing device provided by the embodiment of the application not only greatly reduces the self weight, but also provides rowing inertia corresponding to actual rowing, and solves the problems that the integral weight and the volume of the rowing machine are very large due to the fact that the mechanical flywheel of the rowing machine increases the rowing inertia for the rowing machine by increasing the weight in the prior art, so that the rowing machine is inconvenient to use and carry, and the beneficial effects that the volume is small, the weight is light, and the provided rowing inertia is consistent with the actual rowing are achieved.
It should be further noted that, the manner of mechanically connecting the supercapacitor module 120 with the motor 110 by using the wires is more flexible than that of mechanically connecting the supercapacitor module 110, and the specific setting position of the supercapacitor module 120 can be flexibly arranged according to the actual design situation of the rowing machine.
In addition, as shown in fig. 1, other electric equipment on the rowing machine 200, such as the rowing machine controller 210, can be electrically connected with the supercapacitor module 120 to supply power to the electric equipment such as the rowing machine controller 210, so that energy generated by rowing is effectively utilized, and the beneficial effects of energy conservation and environmental protection are achieved.

When the brush motor 112 rotates at a reduced speed or stops rotating, the output voltage of the brush motor 112 is smaller than the voltage of the supercapacitor module 120, the supercapacitor module 120 discharges (i.e. has a discharging module), the discharging process of the supercapacitor module 120 can promote the rotation acceleration of the brush motor 112, and further promote the rotation acceleration of the transmission shaft of the rowing machine, so that rowing inertia is provided when rowing is reduced or rowing is stopped, and the reality and the fun of rowing experience are further enhanced.

The working mode comprises a motor mode and a generator mode, wherein when the motor is in the motor mode, the motor is a driving part, receives the electric energy of the super capacitor module and drives a transmission shaft of the rowing machine to rotate; when the motor is in a charging mode, the motor is a charging component, receives energy transmitted by a transmission shaft of the rowing machine, and charges the super capacitor module.

When the brushless motor 111 is decelerated or stopped, the output voltage of the brushless motor 111 is smaller than the voltage of the supercapacitor module 120, the supercapacitor module 120 discharges, the discharging process of the supercapacitor module 120 promotes the acceleration of the rotation of the brushless motor 111, and further promotes the acceleration of the rotation of the transmission shaft of the rowing machine, so that the rowing inertia is provided when rowing is decelerated or rowing is stopped, and the reality and the fun of rowing experience are further enhanced.
