Description

Technical Field

[0001] The utility model relates to a fitness bike control device, in particular to a fitness bike resistance control device. Background Art

[0002] The resistance system of traditional flywheel exercise bikes is roughly divided into two types: permanent magnet resistance system and electromagnetic resistance system. When the resistance of the permanent magnet resistance system (hard magnet) needs to be controlled and changed, it can only be adjusted manually, and its reaction time is delayed and cannot react immediately. Therefore, it cannot react synchronously with the terrain and ground changes in virtual reality (such as uphill and downhill sections or emergency braking).

[0003] In addition, although the electromagnetic resistance system (soft magnetic) can provide instant response to changes in resistance size, it lacks joint control with the intelligent resistance adjustment device, so it can neither respond to emergency braking nor provide various resistance offset level changes of different difficulty levels. Therefore, it cannot be applied to various virtual reality software.

[0004] In summary, the disadvantages of the traditional flywheel exercise bike resistance control device are:

[0005] 1. The change of resistance size of the traditional permanent magnet resistance system can only be driven by manual control, but there is a delay in the reaction time of the resistance change, and it is impossible to achieve the effect of instant response through computer control.

[0006] 2. The traditional permanent magnet resistance system, because its resistance change is mainly controlled manually, the traditional permanent magnet resistance system cannot respond instantly to various changes in virtual reality.

[0007] 3. The traditional permanent magnet resistance system cannot change instantly with the slope in virtual reality because of the delay in the reaction time of its resistance change.

[0008] 4. Although the traditional electromagnetic resistance system can instantly respond to changes in its resistance size, it lacks joint control with the intelligent resistance adjustment device, and therefore cannot quickly respond to the immediate conditions of the human-vehicle interface.

[0009] 5. Although the traditional electromagnetic resistance system can instantly respond to changes in its resistance size, it lacks joint control with the intelligent resistance adjustment device, and therefore cannot reflect the fun of the human-vehicle interface during the interaction process.

[0010] 6. The traditional electromagnetic resistance system has no intelligent resistance adjustment device, so it is too controversial in terms of fairness in group training or competition.

[0011] 7. Traditional electromagnetic or permanent magnet resistance systems have no intelligent resistance adjustment device, so they cannot change at any time to match the different difficulty levels in virtual reality.

[0012] 8. Traditional electromagnetic or permanent magnet resistance systems lack human-machine interface integration with intelligent resistance adjustment devices, making it impossible for users to perform power training (Functional Threshold Power, FTP).

[0013] 9. The traditional electromagnetic or permanent magnet resistance system cannot achieve the purpose of cardiopulmonary training for users due to the lack of human-machine interface with the intelligent resistance adjustment device.

[0014] 10. The traditional electromagnetic or permanent magnet resistance system, due to the lack of interaction with the human-machine resistance control drive device, makes it impossible for users to achieve the training state of integration of man, machine and computer during fitness training.

[0049] The specific technical solution adopted by the present utility model will be further described through the following specific implementation methods and drawings.

[0050] See also Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 It is a three-dimensional diagram of the resistance control device of the fitness bike of the present invention combined with the flywheel, and Figure 2 This is a side view of the resistance control device of the fitness bike of the present invention combined with a flywheel. Figure 3 This is a three-dimensional exploded view of the relevant components of the resistance control device for a fitness bike of the present invention when they are separated. Figure 1 As shown, the resistance control device 100 of the fitness bike of the present invention is provided with a resistor 2 near the outer edge of a flywheel 1. When the user uses the fitness bike to drive the flywheel 1 to rotate, the resistance control device 100 of the fitness bike of the present invention can control the resistor 2 and thus adjust the resistance of the flywheel 1.

[0051] The resistor 2 includes one or more permanent magnet units 21 and a shaft column 22. When a thrust is applied, a swing arm 23 can swing around the shaft column 22, so that the swing arm 23 of the resistor 2 approaches or moves away from the outer edge of the flywheel 1.

[0052] See also Figure 4 and Figure 5 As shown, Figure 4 It is a three-dimensional diagram of the resistance control device of the fitness bike of the present invention. Figure 5 for Figure 4 The cross-sectional view of the AA section. The resistance control device 100 of the fitness bike of the present invention comprises: a lower housing 3. The resistance control device 100 of the fitness bike can be mounted and fixed on the frame of a known fitness bike (not shown in the drawings) through the lower housing 3.

[0053] An upper housing 4 is slidably combined in the lower housing 3, and a plurality of batteries 5, a power unit 6, and a control board 7 are accommodated in the upper housing 4. Each battery 5 is arranged at a side of the power unit 6. The power unit 6 is electrically connected to the battery 5 and the control board 7. A display 41 can be arranged on the top surface of the upper housing 4, and the display 41 can display various setting values ​​or exercise values ​​of the resistance control device of the fitness vehicle of the present invention.

[0054] An external electronic device 8 can communicate with the control board 7 in a wireless manner. After the resistance adjustment signal S1 generated by the external electronic device 8 is transmitted to the control board 7, the control board 7 can drive the power unit 6 to rotate, and then drive the transmission rod 62 to rotate through a transmission component 61 of the power unit 6. The transmission rod 62 passes through a through hole of the lower housing 3 and extends downward from the lower housing 3. The bottom of the transmission rod 62 has a screw thread 63, and the transmission rod 62 is screwed and connected to a support plate 24 of the resistor 2.

[0055] When the transmission rod 62 rotates clockwise, the resistor 2 can be pushed to swing around the shaft column 22, so that the swing arm 23 of the resistor 2 approaches the outer edge of the flywheel 1 (such as Figure 2 As shown in FIG. 1 , the permanent magnet unit 21 applies a resistance to the flywheel 1 , thereby increasing the resistance of the user during exercise.

[0056] When the transmission rod 62 rotates counterclockwise, the resistor 2 can be pushed to swing around the shaft column 22, so that the swing arm 23 of the resistor 2 is away from the outer edge of the flywheel 1 (such as Figure 6 As shown in FIG. 1 , the resistance of the user during exercise can be reduced.

[0057] Since the upper housing 4 is formed with one or more guide structures 42 (such as grooves or convex rails) on the side wall, and the lower housing 3 is provided with corresponding guide structures, the upper housing 4 can be slidably combined in the lower housing 3, and there is a travel distance between the bottom of the upper housing 4 and the lower housing 3. When the user applies a downward pressure to the upper housing 4, the transmission rod 62 can be pushed downward, so that the resistor 2 directly applies a strong resistance to the flywheel 1, so that the emergency brake stop function can be achieved.

[0058] Through the above-mentioned design, the utility model can be applied according to the target requirements of virtual reality technology and group sports training, group sports competition, sports training, and cardiopulmonary training to coordinate with the changes in terrain in virtual reality (such as the changes in the slope of uphill and downhill sections and the changes in the resistance and resistance level of difficulty when riding on various terrains), changes in ground objects (such as emergency braking), changes in different difficulty levels of virtual reality, and other changes in virtual reality to produce synchronization effects, so that users can achieve a training state of integration of man, machine, and control device when performing fitness training. Further, the design of the utility model can instantly reflect the real-time status of the interaction between the human and the vehicle and the fun of the interactive process of the human and vehicle interface.

[0059] In actual application, the resistance control device for a fitness bike of the utility model can be used for fitness equipment such as fitness bikes, rowing machines, indoor bicycle trainers, elliptical machines, step machines, climbing machines, treadmills, flywheel bikes, etc.
