[0002] With the development of national fitness activities, indoor fitness products have become increasingly prevalent in people's daily lives. Among these products, exercise bikes, a type of exercise bike, can generate electricity through active cycling, which in turn powers electronic devices. The armature reaction of the generator also provides resistance during cycling.

[0003] However, as the types of load electronic devices become more diverse, the power consumption of different load electronic devices varies greatly, resulting in different riding resistance. This leads to large fluctuations in the resistance effect of exercise bikes, affecting the riding experience. Summary of the Invention

[0004] This invention provides a magnetic resistance adjustment device and an exercise bike, which can solve the problem of large fluctuations in the resistance effect of the exercise bike caused by the difference in the power consumption of the load electronic device.

[0009] The adjustment module is used to adjust the position of the magnetoresistive module according to the power consumption.

[0010] In some embodiments, when the power consumption of the load electronic device is a first power, the adjustment module adjusts the magnetoresistive module to a first target position;

[0022] The first connecting rod is hinged and fixed in the middle, and the first end of the first connecting rod is provided with a sector gear. The second end of the first connecting rod is connected to one end of the second connecting rod, and the other end of the second connecting rod is connected to the movable unit.

[0025] When the sector gear rotates in the second direction, the second end of the first connecting rod rotates in the second direction. The first connecting rod drives the second connecting rod to move in the second direction, and the second connecting rod drives the movable unit to move in the second direction, thereby increasing the magnetic resistance generated by the magnetoresistive module.

[0026] Wherein, the first direction and the second direction are opposite directions.

[0027] In some embodiments, the transmission unit further includes a gear assembly, the gear assembly including at least one transmission gear meshing between the drive unit and the sector gear section.

[0039] In some embodiments, the magnetoresistive module is located on the outer peripheral surface of the rotor assembly;

[0040] The exercise bike is configured such that when the detection module detects that the power consumption of the load electronic device is a first power, the adjustment module adjusts the magnetoresistive module away from the rotor assembly to a first target position, thereby reducing the magnetic resistance between the magnetoresistive module and the rotor assembly.

[0041] When the detection module detects that the power consumption of the load electronic device is the second power, the adjustment module adjusts the magnetoresistive module to move closer to the rotor assembly to the second target position, thereby increasing the magnetic resistance between the magnetoresistive module and the rotor assembly;

[0042] Wherein, the first power is less than the second power.

[0043] The beneficial effects of the technical solution provided by this invention include at least the following:

[0044] The magnetoresistive adjustment device of the present invention uses a detection module to detect the power consumption of the load electronic device, and an adjustment module adjusts the distance between the magnetoresistive module and the rotor assembly of the generator according to the power consumption. This correlates the power consumption of the load electronic device with the resistance level of the exercise bike, so that when the exercise bike supplies power to different load electronic devices, the magnetoresistive module can compensate for the armature reaction, so that the resistance effect fed back by the exercise bike is not affected by the power consumption and is always maintained at the same resistance level, thereby improving the riding experience of exercise bike products.

[0065] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0066] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the appendix. Figure 5 , 6 The orientations or positional relationships shown are for the purpose of facilitating and simplifying the description of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0067] Unless otherwise defined, all technical terms used in the embodiments of this invention have the same meaning as commonly understood by one of ordinary skill in the art.

[0068] Exercise bikes, also known as spin bikes, indoor bikes, etc., are a typical type of aerobic fitness equipment that simulates outdoor exercise (as opposed to anaerobic fitness equipment).

[0069] The exercise bikes in this technology have self-generating power capabilities. On the one hand, they can use generators to produce resistance, simulating real riding resistance. On the other hand, they can power other load electronic devices, such as mobile phones, tablets, and other display devices.

[0070] Due to the generator's own "armature reaction," when the number of load electronic devices connected to the generator increases, and when the power consumption of a single load electronic device increases, the load current increases accordingly, generating a force that hinders the generator's rotation. Since this resistance is additional, it causes a significant difference between the riding resistance fed back to the user by the exercise bike and the normal resistance level, resulting in a poor riding experience.

[0071] Therefore, the present invention provides a magnetoresistive adjustment device, which enables the magnetoresistive module to compensate for the armature reaction when the exercise bike supplies power to different load electronic devices, so that the resistance effect fed back by the exercise bike is not affected by the power consumption, thereby improving the riding experience of exercise bike products.

[0072] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0073] On the one hand, combined with Figure 1-3 As shown, this embodiment provides a magnetoresistive adjustment device 10, which includes a detection module 1, an adjustment module 2, and a magnetoresistive module 3.

[0074] The detection module 1 is used to detect the power consumption of the load electronic device; for example, the detection module 1 includes at least one of a current sensor and a voltage sensor, and obtains one or more electrical parameters that can reflect the power consumption of the load electronic device by detecting the current or voltage of the load electronic device.

[0075] The adjustment module 2 is electrically connected to the detection module 1, and the magnetoresistive module 3 is connected to the adjustment module 2; the adjustment module 2 is used to adjust the position of the magnetoresistive module 3 according to the power consumption.

[0076] In this embodiment, the magnetoresistive adjustment device 10 uses the detection module 1 to detect the power consumption of the load electronic device, and the adjustment module 2 adjusts the position of the magnetoresistive module 3 according to the power consumption, thus relating the power consumption of the load electronic device to the resistance level of the exercise bike. This allows the magnetoresistive module 3 to compensate for the armature reaction when the exercise bike supplies power to different load electronic devices, so that the resistance effect fed back by the exercise bike is not affected by the power consumption and is always maintained at the same resistance level, thereby improving the riding experience of exercise bike products.

[0077] In some possible implementations, in the exercise bike products of this embodiment, the user drives the rotor assembly 4 to rotate through components such as pedals. The rotor assembly 4 is subjected to the armature reaction of the generator 20 and the magnetic resistance of the magnetoresistive module 3, simulating the riding resistance of a real riding scenario, and is fed back to the user through components such as pedals.

[0078] In some other possible implementations, the load electronics can be connected to the output port of the generator 20 to supply power by the electrical energy generated by the relative rotation of the rotor assembly 4 and the stator assembly 5, or to fast charge or slow charge the battery inside the equipment.

[0079] In some possible implementations, when the regulating module 2 adjusts the position of the reluctance module 3 according to the power consumption, the distance between the reluctance module 3 and the rotor assembly 4 of the generator 20 changes, thereby changing the rotational resistance of the generator 20.

[0080] According to the principle of magnetic force, the smaller the distance between the magnetic reluctance module 3 and the rotor assembly 4, the greater the resistance effect of the magnetic reluctance module 3 on the rotor assembly 4; the larger the distance between the magnetic reluctance module 3 and the rotor assembly 4, the smaller the resistance effect of the magnetic reluctance module 3 on the rotor assembly 4.

[0081] For example, the magnetoresistive module 3 can be located on the outside or inside of the rotor assembly 4, which contains a permanent magnet or an energized coil. The magnetoresistive module 3 can generate an attractive or repulsive force with the permanent magnet or energized coil in the rotor assembly 4, thereby increasing the rotational resistance of the rotor assembly 4 and achieving a magnetic resistance effect.

[0082] The load electronic device in this embodiment is a portable electronic device, such as a smartphone, tablet computer, MP3 player (Moving Picture Experts Group Audio Layer III), MP4 player (Moving Picture Experts Group Audio Layer IV), laptop computer, or desktop computer.

[0083] The load electronic device in this embodiment can also be other products, such as electric shavers, electric toothbrushes, service point terminals, wearable devices, and automotive, medical, and industrial products.

[0084] Combination Figure 3 , 4 As shown, in some embodiments, when the power consumption of the load electronic device is a first power, the adjustment module 2 adjusts the magnetoresistive module 3 to a first target position; when the power consumption of the load electronic device is a second power, the adjustment module 2 adjusts the magnetoresistive module 3 to a second target position; wherein, the first power is less than the second power, and the magnetic resistance generated when the magnetoresistive module 3 is located at the first target position is greater than the magnetic resistance generated when the magnetoresistive module 3 is located at the second target position.

[0085] For example, when the magnetoresistive module 3 is located at the first target position, the distance between it and the rotor assembly 4 of the generator 20 is relatively large, resulting in a smaller magnetic attraction force and a smaller feedback riding resistance. When the magnetoresistive module 3 is located at the second target position, the distance between it and the rotor assembly 4 of the generator 20 is relatively small, resulting in a larger magnetic attraction force and a larger feedback riding resistance.

[0086] When the power consumption of the load electronic device increases, the load current of the generator 20 increases, the armature reaction strengthens, and the output resistance of the generator 20 increases. Then, the adjustment module 2 controls the distance between the magnetic reluctance module 3 and the rotor assembly 4 to increase, thereby reducing the magnetic resistance. The total resistance fed back to the user by the exercise bike remains basically unchanged. When the power consumption of the load electronic device decreases, the load current of the generator 20 decreases, the armature reaction weakens, and the output resistance of the generator 20 decreases. Then, the adjustment module 2 controls the distance between the magnetic reluctance module 3 and the rotor assembly 4 to decrease, thereby increasing the magnetic resistance. The total resistance fed back to the user by the exercise bike remains at the target level.

[0087] Thus, the magnetic resistance adjustment device 10 detects the power consumption of the load electronic device in real time through the detection module 1, and adjusts the distance between the magnetic resistance module 3 and the rotor assembly 4 in real time according to the power consumption, that is, adjusts the magnitude of the magnetic resistance, compensates for the resistance fluctuations of the generator 20 caused by the change of load current, so that the total resistance fed back to the user by the exercise bike is stably maintained at the target level, thereby improving the riding experience of the exercise bike.

[0088] Combination Figure 3 , 4 As shown, in some embodiments, the adjustment module 2 includes a control unit and a drive unit 22; the detection module 1 is electrically connected to the control unit, and the detection module 1 inputs a first signal corresponding to the power consumption of the load electronic device to the control unit; the control unit is electrically connected to the drive unit 22, and the control unit determines the control strategy of the drive unit 22 according to the first signal, and inputs a second signal corresponding to the control strategy to the drive unit 22; the drive unit 22 is connected to the magnetoresistive module 3, and the drive unit 22 drives the magnetoresistive module 3 to move in response to the second signal.

[0089] The adjustment module 2, using the control unit and drive unit 22, can automatically respond to power changes of the load electronic equipment without human intervention, which helps to improve the automation level of the magnetoresistive adjustment device 10 and enhance the user experience of exercise bikes.

[0090] The types of drive units 22 include, but are not limited to, electric motors, electric cylinders, electrostrictive memory metals, etc.

[0091] It should be noted that the connection between the magnetoresistive module 3 and the drive unit 22 can be a direct connection, that is, the action of the drive unit 22 directly acts on the magnetoresistive module 3, causing it to move accordingly; or it can be an indirect connection, where the drive unit 22 transmits the force to the magnetoresistive module 3 by changing the position and shape of other structural components, causing it to move accordingly.

[0092] Combination Figure 3 , 4As shown, in some embodiments, the adjustment module 2 further includes a transmission unit 23 and a movable unit 24; the drive unit 22 is connected to the transmission unit 23, the transmission unit 23 is connected to the movable unit 24, and the movable unit 24 is connected to the magnetoresistive module 3; the drive unit 22 drives the transmission unit 23 in response to the second signal, the transmission unit 23 drives the movable unit 24, and the movable unit 24 drives the magnetoresistive module 3 to move.

[0093] The transmission unit 23 improves the stability and reliability of power transmission in the adjustment module 2, enabling it to meet the application requirements of different scenarios. For example, the drive unit 22 can be positioned away from the magnetoresistive module 3. Using the movable unit 24 as a support structure to move the magnetoresistive module 3 also meets the application requirements of different scenarios.

[0094] In some possible implementations, the magnetoresistive module 3 can move in one or more of the following ways: sliding, translation, and rotation. Using any of these movement methods, the position of the magnetoresistive module 3 can be changed, thereby altering the distance between the magnetoresistive module 3 and the rotor assembly 4, changing the magnetic force between them, and adjusting the magnitude of the magnetic resistance output by the magnetoresistive module 3. The movement method of the magnetoresistive module 3 can be reasonably selected according to the requirements of the scenario. For example, refer to... Figure 2 , 3 Driven by the movable unit 24, the magnetoresistive module 3 can rotate and move upward or downward with its lower left end as the center. When the upper right end of the magnetoresistive module 3 rotates upward, the distance between the magnetoresistive module 3 and the rotor assembly 4 decreases, and the magnetic resistance generated by the two increases. When the lower right end of the magnetoresistive module 3 rotates downward, the distance between the magnetoresistive module 3 and the rotor assembly 4 increases, and the magnetic resistance generated by the two decreases.

[0095] Combination Figure 3 , 4 As shown, in some embodiments, the transmission unit 23 includes a first connecting rod 231 and a second connecting rod 232; the first connecting rod 231 is hinged and fixed in the middle, and a sector gear portion 2311 is provided at the first end of the first connecting rod 231. The second end of the first connecting rod 231 is connected to one end of the second connecting rod 232, and the other end of the second connecting rod 232 is connected to the movable unit 24; the sector gear portion 2311 is meshed with the drive unit 22, and the drive unit 22 drives the first connecting rod 231 to rotate through the sector gear portion 2311. The first connecting rod 231 drives the second connecting rod 232 to move, and the second connecting rod 232 drives the movable unit 24 to move.

[0096] In this embodiment, the transmission unit 23 utilizes a first connecting rod 231, which is similar to a lever. When the sector gear portion 2311 of the first connecting rod 231 rotates under the action of meshing force, the other end of the first connecting rod 231 rotates synchronously, thereby driving the second connecting rod 232 to move. The second connecting rod 232 drives the movable unit 24 to move, and the movable unit 24 drives the magnetic reluctance module 3 to move, thereby changing the distance between the magnetic reluctance module 3 and the rotor assembly 4.

[0097] Combination Figure 3 , 4 As shown, in some embodiments, when the sector gear 2311 rotates in the first direction, the second end of the first connecting rod 231 rotates in the first direction, the first connecting rod 231 drives the second connecting rod 232 to move in the first direction, and the second connecting rod 232 drives the movable unit 24 to move in the first direction, thereby increasing the magnetic resistance generated by the magnetoresistive module 3; when the sector gear 2311 rotates in the second direction, the second end of the first connecting rod 231 rotates in the second direction, the first connecting rod 231 drives the second connecting rod 232 to move in the second direction, and the second connecting rod 232 drives the movable unit 24 to move in the second direction, thereby decreasing the magnetic resistance generated by the magnetoresistive module 3; wherein, the first direction and the second direction are opposite directions.

[0098] The sector gear 2311 is controlled to rotate in different directions, and the first connecting rod 231 also rotates in different directions. The second end of the first connecting rod 231 drives the second connecting rod 232 to move in different directions. The second connecting rod 232 drives the movable unit 24 to move, thereby changing the position of the magnetoresistive module 3 and changing the magnetic resistance accordingly.

[0099] For example, refer to Figure 3 The first direction is counterclockwise. Under the action of the first link 231, the second link 232 moves upward, the upper right end of the movable unit 24 moves upward, and the magnetic reluctance module 3 moves upward and closer to the rotor assembly 4, thereby increasing the magnetic resistance. The second direction is clockwise. Under the action of the first link 231, the second link 232 moves downward, the upper right end of the movable unit 24 moves downward, and the magnetic reluctance module 3 moves downward and away from the rotor assembly 4, thereby decreasing the magnetic resistance.

[0100] Combination Figure 3 , 4 As shown, in some embodiments, the transmission unit 23 further includes a gear assembly 233, which includes at least one transmission gear meshing between the drive unit 22 and the sector gear section 2311. The use of the gear assembly 233 enables stable and reliable transmission of force between the drive unit 22 and the sector gear section 2311, and has advantages such as high precision and high reliability.

[0101] It should be noted that the number of transmission gears, such as one, two, three, etc., can be reasonably selected according to the actual scenario, including the number, diameter, and arrangement of the gears.

[0102] Combination Figure 2 , 3 As shown, in some embodiments, at least one transmission gear includes a first gear 2331 and a second gear 2332; the drive unit 22 is meshed with the first gear 2331, the first gear 2331 is meshed with the second gear 2332, and the second gear 2332 is meshed with the sector gear section 2311, wherein the diameter of the first gear 2331 is smaller than the diameter of the second gear 2332. Therefore, when the first gear 2331 and the second gear 2332 are used to transmit rotational torque, a speed-reducing and torque-increasing effect can be achieved.

[0103] Combination Figure 3 As shown, in some embodiments, the transmission unit 23 further includes a worm gear 234, which is located on the output shaft of the drive unit 22 and meshes with the gear assembly 233. The worm gear 234 allows for changing the direction of the power output by the drive unit 22, making the arrangement of the drive unit 22 and the transmission unit 23 more flexible and improving the structural flexibility of the reluctance adjustment device 10.

[0104] Combination Figure 3 , 4 As shown, in some embodiments, the magnetoresistive module 3 includes at least one magnetic element 31; the movable unit 24 includes a support 241, at least one magnetic element 31 is located on the support 241 and arranged in an arc shape; the first end of the support 241 is fixed in position, the second end of the support 241 is connected to the transmission unit 23, the transmission unit 23 drives the second end of the support 241 to move, and the support 241 drives at least one magnetic element 31 to rotate around the first end of the support 241.

[0105] For example, the number of magnetic components 31, such as one, two, three, etc., can be reasonably selected according to the actual scenario.

[0106] For example, the magnetic element 31 is arranged in an arc shape on the outer circumference of the rotor assembly 4 using the support member 241, so that the facing area between the magnetic element 31 and the rotor assembly 4 is large, which is beneficial to improving the magnetoresistive effect of the magnetoresistive module 3.

[0107] Optionally, the second end of the support member 241 is connected to the second connecting rod 232. The first end of the support member 241 is fixed. When the second end of the support member 241 is pulled outward by the second connecting rod 232, the magnetic element 31 on the second end of the support member 241 moves away from the rotor assembly 4, and the magnetic resistance decreases. When the second end of the support member 241 is pushed outward by the second connecting rod 232, the magnetic element 31 on the second end of the support member 241 moves closer to the rotor assembly 4, and the magnetic resistance increases.

[0108] On the other hand, combining Figure 5 , 6 As shown, this embodiment provides an exercise bike, which includes: the magnetic resistance adjustment device 10 of the present invention, as well as a generator 20 and a load interface 30.

[0109] The detection module 1 is electrically connected to the load interface 30, and the detection module 1 can detect the power consumption of the load electronic device connected to the load interface 30; the generator 20 includes a stator assembly 5 and a rotor assembly 4, and the magnetic resistance adjustment device 10 is close to the rotor assembly 4, and the magnetic resistance adjustment device 10 provides magnetic resistance to the rotor assembly 4; the load interface 30 is electrically connected to the power output port of the generator 20, and the generator 20 can supply power to the load electronic device connected to the load interface 30.

[0110] The exercise bike in this embodiment uses the magnetic resistance adjustment device 10 of the present invention, and has all the technical effects of the present invention. The exercise bike can automatically adjust the magnetic resistance generated by the magnetic resistance adjustment device 10 according to the power consumption of the load electronic equipment, and compensate for the power generation resistance generated by the generator 20, so that the overall riding resistance fed back by the exercise bike is balanced and maintained at the target level, resulting in a better riding experience.

[0111] In some possible implementations, the load interface 30 includes, but is not limited to, a USB interface, a Type-C interface, a Lightning interface, a wireless charging coil, etc. The load interface 30 can provide wired or wireless power to the load electronic device.

[0112] Combination Figure 5 , 6 As shown, the exercise bike also includes a cycling wheel module 40, which includes a drive wheel 6 and a foot pedal 7. The foot pedal 7 is connected to the drive wheel 6. The drive wheel 6 is connected to the rotor assembly 4. The magnetic resistance adjustment device 10 provides magnetic resistance to the rotor assembly 4. The rotor assembly 4 feeds back the cycling load to the drive wheel 6 and the foot pedal 7.

[0113] The user drives the drive wheel 6 to rotate by stepping on the pedal 7. The drive wheel 6 drives the rotor assembly 4 to rotate, while the stator assembly 5 remains fixed. The rotor assembly 4 and stator assembly 5 rotate relative to each other, generating electrical energy. This energy is then transmitted to the load interface 30 through the power output port, and then from the load interface 30 to the load electronic device. During the relative rotation of the rotor assembly 4 and stator assembly 5, armature reaction is overcome, thus generating a portion of riding resistance. The magnitude of this riding resistance is related to the power consumption of the load electronic device; the higher the power consumption, the greater the riding resistance. The magnetic reluctance module 3 in the magnetic reluctance adjustment device 10 attracts the rotor assembly 4, generating another portion of riding resistance. The magnitude of this riding resistance is related to the distance between the magnetic reluctance module 3 and the rotor assembly 4; the smaller the distance, the greater the riding resistance.

[0114] Among some possible implementations, refer to Figure 5 , 6 The magnetoresistive module 3 is located on the outer peripheral surface of the rotor assembly 4.

[0115] The exercise bike is configured such that when the detection module 1 detects that the power consumption of the load electronic device is a first power, the adjustment module 2 adjusts the magnetic reluctance module 3 away from the rotor assembly 4 to a first target position, thereby increasing the magnetic resistance between the magnetic reluctance module 3 and the rotor assembly 4; when the detection module 1 detects that the power consumption of the load electronic device is a second power, the adjustment module 2 adjusts the magnetic reluctance module 3 closer to the rotor assembly 4 to a second target position, thereby decreasing the magnetic resistance between the magnetic reluctance module 3 and the rotor assembly 4; wherein the first power is less than the second power.

[0116] When the user connects the load electronics to the load interface 30, they need to quickly press the foot pedal 7 to rotate the rotor assembly 4, thereby outputting electrical energy to meet the power consumption of the load electronics. At the same time, the detection module 1 detects the power consumption of the load electronics and determines the corresponding control strategy through a pre-stored mapping relationship, thereby adjusting the reluctance module 3 to the target position, that is, the distance between the reluctance module 3 and the rotor assembly 4 is adjusted to the target distance. At this time, the magnetic resistance generated between the reluctance module 3 and the rotor assembly 4 is a fixed value, which is inversely proportional to the power of the load electronics, while the armature resistance of the generator 20 itself is directly proportional to the power of the load electronics.

[0117] Thus, when the exercise bike supplies power to high-power load electronic devices, the armature resistance increases, but the magnetic resistance decreases accordingly. Conversely, when supplying power to low-power load electronic devices, the armature resistance decreases, and the magnetic resistance increases accordingly. This ensures that the riding resistance fed back from the rotor assembly 4 of the generator 20 to the drive wheel 6 and the pedals 7 remains stable.

[0118] Among some possible implementations, refer to Figure 5 , 6 The exercise bike also includes a frame, seat module 50, handlebar module 60, and load support 70.

[0119] The frame serves as the skeleton of the exercise bike, supporting all its structural components.

[0120] The generator 20 and the riding wheel module 40 are located at the lower part of the frame. The drive wheel 6 is connected to the rotor assembly 4 via chain drive, belt drive, or other means. The seat module 50 and the handlebar module 60 are located at the upper part of the frame. The seat module 50 corresponds to the riding wheel module 40. When the user sits on the seat module 50, both feet can be placed on the pedals 7, thereby driving the drive wheel 6 and the rotor assembly 4 to rotate by stepping on the pedals 7.

[0121] In addition to handlebars for users to grip with both hands, the handlebar module 60 can also have a switch button, display screen, etc., for turning the exercise bike on and off, as well as setting and displaying the exercise bike's operating status.

[0122] The load holder 70 is located above the handlebar module 60 and can support the load electronics directly in front of the user. Optionally, the load interface 30 is a wireless charging coil. When the load electronics are located on the load holder 70, the load interface 30 is coupled to the load electronics and can wirelessly charge the load electronics.
