The present invention relates to stationary exercise equipment, and more particularly to an intelligent resistance adjustment system for stationary exercise equipment.
Resistance systems for traditional flywheel-based stationary bicycles are generally classified in two types, which are permanent magnet resistance system and electromagnetic resistance systems. For control and variation of the resistance, the permanent magnet resistance system (also referred to as “hard magnet”) totally relies on manual operations to make desired variation. Consequently, there will always be time delay in responding and no instantaneous response may be achieved, and as such, it does not provide synchronization for use with landforms and terrain features (such as moving uphill or downhill or emergence braking) of a virtual-reality environment.
The electromagnetic resistance system (also referred to as “soft magnet”) is capable of making instantaneous response for varying resistance. However, it does not make response to situations of emergency braking, and is also not available for change of difficulty level in respect of resistance offset, if it is not combined with and controlled by an intelligent resistance adjustment device, and thus, it is not suit for to different sorts of virtual-reality software.
In brief, the known resistance adjustment systems for flywheel-based stationary exercise equipment suffers the following drawbacks:
(1) The known permanent magnet resistance system relies on manual operation to control and vary resistance, and there is a time delay in responding to resistance variation, and thus, it does not provide an effect of computer-controlled instantaneous response.
(2) The known permanent magnet resistance system relies on manual operation to control and vary resistance, and is thus not applicable to situations of change in virtual reality that requires immediate responses.
(3) The known permanent magnet resistance system suffers time delay in responding to resistance variation, and thus, it is not suit for scenario of slope variation in virtual reality.
(4) The known electromagnetic resistance system, although capable of instantaneous response to resistance variation, lacks connection with intelligent resistance adjustment and is thus incapable of emergent response to an instantaneous situation of a man-vehicle interface.
(5) The known electromagnetic resistance system, although capable of instantaneous response to resistance variation, lacks connection with intelligent resistance adjustment and is thus incapable of allowing for enjoyment of interaction with a man-vehicle interface.
(6) The known electromagnetic resistance system does not include an intelligent resistance adjustment device, and this leads to severe concern of fairness for group training or competition.
(7) The known electromagnetic or permanent-magnet resistance system does not include an intelligent resistance adjustment device, and this makes it impossible for change of difficulty level in virtual reality.
(8) The known electromagnetic or permanent-magnet resistance system lacks integration with a man-vehicle interface of an intelligent resistance adjustment device, and this makes it impossible for a user to take functional threshold power (FTP) training.
(9) The known electromagnetic or permanent-magnet resistance system lacks connection with a man-vehicle interface of an intelligent resistance adjustment device, and this makes it impossible to enable a user to take cardiovascular training.
(10) The known electromagnetic or permanent-magnet resistance system lacks connection with a man-vehicle resistance control and drive device so as not to enable a user to achieve such a level of man-machine-computer integration during the exercise training.
Thus, the primary objective of the present invention is to provide a resistance adjustment system for stationary exercise equipment, which helps improve the drawbacks of a known stationary bicycle resistance system and provides an intelligent resistance system for stationary exercise equipment that is fit for virtual reality technology and group exercise training.

In another embodiment, the present invention comprises a resistance control circuit with a signal input/output interface for receiving a resistance value signal transmitted from an electronic device; a power source for supplying electricity to the signal input/output interface and the resistance control circuit; a transmission assembly; a manual adjustment member coupled to the transmission assembly; and an electrical adjustment member including an electromagnetic drive unit electrically connected to the electromagnetic resistance device, wherein the electromagnetic drive unit includes an electromagnet signal transceiver and an electromagnetic drive circuit in electrical connection with the electromagnet signal transceiver, wherein the resistance value signal transmitted from the electronic device is transmitted through the signal input/output interface to the electromagnet signal transceiver to allow the electromagnetic drive circuit to drive the electromagnetic resistance device to cause a change of the resisting force applied to the flywheel.
In efficacy, the structural arrangement of the present invention is fit for the virtual reality technology and the need for group exercise training, exercise power training, and cardiovascular training in virtual reality, for being used in a virtual-reality landform (such as slope variation for uphill and downhill and various levels of riding difficulty in respect of resistance and level shifting of resistance), or terrain features (such as emergency braking), or change among different difficulty levels in virtual reality, and so on, for realization of synchronization with various situations in virtual reality, so that during exercise training, the user may achieve a scenario of unification among man, machine, and controller. Further, the structural arrangement of present invention allows for enjoyment of the interesting of instantaneous man-vehicle interaction for emergency and an interaction process of the man-vehicle interface.

When the user forcibly presses down the dual-mode resistance adjustment device 3, a transmission assembly 33 is forced to move downward, so that a braking member 22 of the magnet-based resistance device 2 applies, in a downward direction, a pressing force to a wheel surface of the flywheel 11 to stop the flywheel 11, and thus achieving an effect of emergency braking.
The signal input/output interface 61 is operable to receive a resistance value signal transmitted from an electronic device 7 (such as an electronic bicycle dashboard, a smart mobile phone, a tablet computer, a computer, a workstation, and cloud) for transmission to the processor unit 62, or to transmit a signal from the processor unit 62 to the electronic device 7. The manual adjustment member 31 is also connected to the signal input/output interface 61. The operation signal sensor 63 can be an angle sensor, a turn-count sensor, a stage sensor, or a magnetometer, and said other signal sensors 64 can be example a touch-control sensor, a speed sensor, and the likes.
In the manual operation mode, the user operates the manual adjustment member 31 to control a stroke of the transmission assembly 33, so as to change the magnitude of the resisting force that the magnet-based resistance device 2 applies to the flywheel 11. During the user's manual operation of the manual adjustment member 31, the operation signal detector 63 is also operable to detect an operation signal for transmission to the processor unit 62, and further transmission through the signal input/output interface 61 to the electronic device 7.
In the electrical operation mode, the electronic device 7 generates a resistance value signal that is supplied through the signal input/output interface 61 to the processor unit 62, and then, the processor unit 62 generates, by means of the drive circuit 66, a driving signal to drive the power unit 51 to rotate and thus drive the transmission assembly 33, so as to vary the resisting force that the magnet-based resistance device 2 applies to the flywheel 11. The power unit 51 may be combined with a stroke detection device 531.
In practical uses, taking simulation of a bicycle as an example, the magnet-based resistance device 2 serves as derailleur of the bicycle (meaning applying a first resisting force to the flywheel 11), and the electromagnetic resistance device 2a may serve as control of slope resistance (meaning applying a second resisting force to the flywheel 11).
In practical uses, taking simulation of a bicycle as an example, the magnet-based resistance device 2 serves as derailleur of the bicycle (meaning applying a first resisting force to the flywheel 11), and the pole-coil-based resistance device 2b may serve as control of slope resistance (meaning applying a second resisting force to the flywheel 11).
When the flywheel 11 is rotating, the metal material of the flywheel 11 cut a magnetic field generated by the winding 24, and thus, an eddy current is inducted on the metal material of the flywheel 11. The eddy current and the electromagnetic pole 23 generate a resisting force through mutual attraction or repulsion. The magnitude of the magnetic force generated by the winding 24 can be controlled through a PWM (Pulse Width Modulation) signal.
A lower end of the transmission assembly 33 is mounted with a braking member 4. When the user forcibly presses down the manual adjustment member 31, the transmission assembly 33 is forced to move downward, so that the braking member 4 applies a pressing force to the wheel surface of the flywheel 11 to stop the flywheel 11, and thus achieving an effect of emergency braking.
In the electrical operation mode, the electronic device 7 generates a resistance value signal that is transmitted through the signal input/output interface 61 to the processor unit 62, and is also transmitted through the signal input/output interface 61 to an electromagnet signal transceiver 81 to allow an electromagnetic drive circuit 82 to drive the electromagnetic resistance device 2c so as to change the resisting force applied to the flywheel 11.
Further, the processor unit 62 can be connected, in a wireless or wired manner, with an increment button 341 and a decrement button 342. When the processor unit 62 receives a resistance adjustment signal generated through operation of the increment button 341 and/or the decrement button 342, the processor unit 62 generates a driving signal that is transmitted through the signal input/output interface 61 to the electromagnet signal transceiver 81, in order to allow an electromagnetic drive circuit 82 to drive the electromagnetic resistance device 2c to change the resisting force applied to the flywheel 11.
The increment button 341 and the decrement button 342 can be arranged on a left grip 13a or a right grip 13b that will be discussed hereinafter in a different embodiment (such as that shown in

The stationary bicycle 1 includes a left grip 13a and a right grip 13b that are respectively provided with an increment button 35 and a decrement button 36. Similarly, the increment button 35 and the decrement button 36 can each be a control button of either a mechanical button or a touch-control button.
When the user forcibly presses down the resistance adjustment device 3a, the transmission assembly 33 is forced to move downward, so that the braking member 4 mounted at the lower end of the magnet-based resistance device 2 applies a pressing force to the wheel surface of the flywheel 11 to stop the flywheel 11. Further, the casing 32 of the resistance adjustment device 3a may be provided, on a side wall thereof with a pair of corresponding slide rails 37, for the purposes of reducing frictional force with respect to the frame 10 during operation and movement, in order to make the movement smooth.
Referring to
In the circumference of the casing 32 of the resistance adjustment device 3a, a pushbutton-fashion manual adjustment member 34 is arranged at a predetermined location that is convenient for operation by the user and is in electrical connection with the resistance control circuit 6. When the user operates the pushbutton-fashion manual adjustment member 34, a resistance adjustment signal is generated and applied to the resistance control circuit 6.
The pushbutton-fashion manual adjustment member 34 comprises an increment button 341 and a decrement button 342. In a preferred embodiment, the pushbutton-fashion manual adjustment member 34 may also comprises a mode selection button 343 and a setting button 344.

In the instant embodiment, an angle detection unit 532 may be further included, which can be one of a magnetic material, an optical material, an encoder, a magnetometer, a gyroscope, a gear, and a Hall sensor. For example, the angle detection unit 532 may comprises a magnetic element and a circuit board that is mounted, in a manner of corresponding thereto, on the transmission assembly 33. When the circuit board is rotated with the rotation of the transmission assembly 33, the magnetic coupling thereof with respect to the magnetic element can be used to detect an angular position of the transmission assembly 33.
The transmission assembly 33 comprises a screw rod, which is connected to a rotary spindle 533 of the power unit 51, and is driven by the rotary spindle 533 to rotate in order to make a moving stroke.
Electrical power required for operation of the resistance control circuit 6 and the power unit 51 can be supplied from and by the power source 52. The power source 52 can be one of a rechargeable battery, a primary battery, and an external electrical power source.
When the processor unit 62 receives a resistance adjustment signal generated through operation of the increment button 341 and/or the decrement button 342, the processor unit 62 generates a driving signal applied to the drive circuit 66, and the drive circuit 66 drives the power unit 51. Power generated by the power unit 51 drives the transmission assembly 33 to generate a moving stroke to the magnet-based resistance device 2.
Upon being driven to rotate, the power unit 51 uses the angle detection unit 532 to detect a rotation angle of the transmission assembly 33 and an angular signal is generated and fed back to the processor unit 62.
During operation, the increment button 35 and the decrement button 36 that are disposed on the left grip 13a and the right grip 13b of the stationary bicycle 1 transmit, by means of signal transmission units 351, 361, in a wireless manner, the resistance adjustment signal to the signal input/output interface 61, for subsequent transmission to the processor unit 62. The processor unit 62 similarly generates a driving signal applied to the drive circuit 66, and the drive circuit 66 drives the power unit 51. Power generated by the power unit 51 drives the transmission assembly 33 to generate a moving stroke to the magnet-based resistance device 2.
Preferably, a resistance adjustment signal generated by an electronic device 7 is transmitted through the signal input/output interface 61 to the processor unit 62, so that the processor unit 62 generates a driving signal to the drive circuit 66, to allow the drive circuit 66 to drive the power unit 51, and then, the transmission assembly 33 generates a moving stroke to the magnet-based resistance device 2.
