Description

Technical Field

[0001] This invention relates to the field of exercise bike braking technology, and more particularly to a mild braking structure and method for exercise bikes. Background Technology

[0002] As people's living standards continue to improve, their awareness of physical fitness and maintenance is also increasing. As a result, various fitness equipment has entered people's daily lives. As an indoor fitness equipment, the exercise bike has the characteristics of small footprint, high fitness efficiency, and simple and convenient use, and is therefore widely favored by fitness enthusiasts.

[0003] In the existing technology, the structure of the exercise bike can refer to the exercise bike provided by CN115738172A. Its pedal and counterweight flywheel structure is similar to that of a bicycle, and it is driven by a track. However, one problem with this structure is that when the user makes an emergency stop, the pedal will still rotate rapidly under the rotational inertia of the counterweight flywheel, which poses a risk of injury to the user's feet.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0036] Obtain the pressing pressure value of the transmission belt on the brake component;

[0037] The pressing pressure value is compared with a first threshold.

[0038] When the pressing pressure value is less than the first threshold, a first riding status signal is generated, which is used to indicate that the adjustment component is activated.

[0060] In the existing technology, the structure of the exercise bike can refer to the exercise bike provided by CN115738172A. Its pedal and counterweight flywheel structure is similar to that of a bicycle, and it is driven by a track. However, one problem with this structure is that when the user makes an emergency stop, the pedal will still rotate rapidly under the rotational inertia of the counterweight flywheel, which poses a risk of injury to the user's feet.

[0061] To address the aforementioned problems in the prior art, this invention provides a mild braking structure for a stationary bicycle, such as... Figure 1 As shown, the mild braking structure of the exercise bike includes: a frame 700, on which a drive wheel 100 and a driven wheel 200 are mounted, connected by a transmission belt 300, and an outer wheel 210, which is a magnetic component, is mounted on the outer side of the driven wheel 200; a brake element 400, rotatably mounted on the frame 700 corresponding to the inner side of the transmission belt 300, the brake element 400 including: a drive arm 410, which rolls against the inner side of the transmission belt 300; a brake arm 420, the end of which is provided with an adjusting element 421, which corresponds to the outer wheel 210, and includes a magnet; and a reset element 500, which is fixedly mounted on the frame 700 and elastically connected to the brake arm 420.

[0062] This invention provides a rotating brake 400 on the frame 700. The drive arm 410 of the brake 400 rolls against the inner side of the transmission belt 300. The adjusting member 421 on the brake arm 420 is a certain distance away from the outer wheel 210. When the user applies force to the drive wheel 100, the drive arm 410 is pressed down by the transmission belt 300, and the adjusting member 421 separates from the outer wheel 210. When the force is stopped, the brake 400 is reset by the reset member 500. This allows the adjusting member 421 and the outer wheel 210 to achieve a gentler braking effect on the driven wheel 200 through the electromagnetic damping principle, reducing the risk of injury to the user.

[0063] In the above embodiments, such as Figure 1 As shown, the main body of the mild braking structure of the exercise bike of the present invention consists of a frame 700, a drive wheel 100, a driven wheel 200, a transmission belt 300, and a brake component 400. The frame 700 is as follows: Figure 4 As shown, those skilled in the art can understand that the function of the frame 700 is to fix the positions of the drive wheel 100, the driven wheel 200 and the brake 400, and its specific shape is not limited in this application.

[0064] The drive wheel 100 and the driven wheel 200 are set in the same horizontal plane. A transmission belt 300 is sleeved on the outside of the drive wheel 100 and the driven wheel 200. The transmission belt 300 is a flexible transmission belt and is made of a material with a large coefficient of friction, such as rubber, to avoid slippage. In actual use, the user can drive the drive wheel 100 to drive the driven wheel 200 to rotate. Since the frame 700 is fixed in position, the effect of simulating cycling in place can be achieved to meet the relevant exercise needs.

[0065] The brake 400 is used to apply gentle braking to the driven wheel 200. The brake 400 is located between the driving wheel 100 and the driven wheel 200, and is situated within the area encircled by the transmission belt 300. As those skilled in the art will understand, in existing exercise bikes, the driven wheel 200 is added with a counterweight to simulate riding resistance. However, this also causes the driven wheel 200 to continue rotating at high speed due to its rotational inertia when the user stops riding or encounters an emergency stop, driving the driving wheel 100 to rotate. This can easily cause injury to the user's feet. Therefore, in this embodiment, a brake 400 is provided to achieve gentle braking. Specifically, an outer wheel 210 is provided on the outside of the driven wheel 200. The outer wheel 210 is fixedly connected to the driven wheel 200 and is made of a magnetic material with conductive properties, such as iron, which can be attracted by a permanent magnet.

[0066] The brake element 400 is rotatably mounted on the frame 700. Specifically, the brake element 400 includes a drive arm 410, which rolls against the inner side of the transmission belt 300. When the user rides, the transmission belt 300 tightens, pressing the drive arm 410, thereby causing the drive arm 410 to rotate the brake element 400. An adjusting element 421 is provided on the brake arm 420. This adjusting element 421 is made of a material containing magnets. In different embodiments of the invention, the adjusting element 421 can be a permanent magnet component, such as a magnet, or an electromagnetic component. In actual use, when the user applies force to ride, the drive arm 410 drives the brake 400 to rotate. At this time, the adjusting member 421 is separated from the outer wheel 210. After the user stops applying force, the transmission belt 300 is in a relaxed state. At this time, the brake 400 rotates back. Under the magnetic attraction, the adjusting member 421 and the outer wheel 210 move closer together. Under the action of electromagnetic damping principle, the effect of slowing down is achieved, thereby limiting the rotational inertia of the driven wheel 200, and thus limiting the continued rotation of the drive wheel 100, so as to avoid the pedal from causing injury to the user.

[0067] In the above embodiment, the principle of electromagnetic damping is as follows: a coil rotating in a magnetic field will generate an induced electromotive force. If the external circuit of the coil is closed, an induced current will be generated in the coil. The magnetic field will generate an Ampere force on the induced current, forming a torque opposite to the original direction of rotation, which will dampen the rotation of the coil. Electromagnetic damping refers to the phenomenon that when a conductor moves in a magnetic field, the induced current will cause the conductor to be subjected to an Ampere force, and the direction of the Ampere force always opposes the direction of the conductor's movement.

[0068] In the above embodiment, in order to achieve rapid reset of the brake 400, the brake 400 also includes a reset member 500. The reset member 500 is fixedly mounted on the frame 700 and elastically connected to the brake arm 420. When the drive arm 410 is pressed, the brake arm 420 moves synchronously and makes elastic contact with the reset member 500 to accumulate elastic potential energy. When the force acting on the drive arm 410 disappears, the brake arm 420 rotates under the action of the elastic potential energy of the reset member 500, thereby achieving the effect of bringing the adjusting member 421 closer to the outer wheel 210.

[0069] Based on the above embodiments, in another possible implementation of the present invention, such as Figure 1 As shown, to avoid the drive arm 410 affecting the normal transmission of the transmission belt 300, a first rotating wheel 411 is provided on the drive arm 410 in this embodiment. The first rotating wheel 411 can rotate freely and, during actual installation, rolls against the inner side of the transmission belt 300. Correspondingly, to keep the brake 400 balanced, the brake 400 in this embodiment also includes a balance arm 430, on which a second rotating wheel 431 is provided. The second rotating wheel 431 can rotate freely and, during actual installation, rolls against the inner side of the transmission belt 300. In a specific embodiment, such as Figure 1 As shown, the drive wheel 100 is located on the left side and the driven wheel 200 is located on the right side. In actual use, the user usually drives the drive wheel 100 counterclockwise. The rotation of the drive wheel 100 drives the driven wheel 200 to rotate. At this time, the transmission belt 300 located above is in a taut state. Therefore, in this embodiment, the drive arm 410 is positioned above the transmission belt 300 and the balance arm 430 is positioned below the transmission belt 300, so that the transmission belt 300 can exert downward pressure on the drive arm 410 during the user's riding process.

[0070] In one possible implementation, a pressure sensor 412 is further provided on the drive arm 410 at a position corresponding to the first wheel 411. This pressure sensor 412 is used to detect the pressure applied by the transmission belt 300 to the drive arm 410, thereby monitoring the riding status of the exercise bike and the intensity of the user's pedaling force through this pressure. Figure 1 As shown, the stronger the user's riding force, the stronger the tension on the drive belt 300, and the stronger the downward pressure on the drive arm 410. At the same time, due to the presence of the reset component 500, elastic potential energy is accumulated synchronously. Therefore, the pressure data acquired by the pressure sensor 412 is constantly changing during this process. Thus, the user's riding intensity can be determined by data acquisition and comparison, and then presented in the smart terminal. The riding status can be judged by the pressure data, which can serve as the basis for adjusting other functional components.

[0071] Furthermore, such as Figure 1 As shown, in this embodiment, the included angle between each pair of the drive arm 410, brake arm 420, and balance arm 430 is 1 degree, meaning that the drive arm 410, brake arm 420, and balance arm 430 are evenly arranged. The advantage of this arrangement is that it can balance the center of gravity of the brake component 400, thereby keeping the brake component 400 stable during rotation. In actual installation, the drive arm 410, brake arm 420, and balance arm 430 are manufactured in one piece to ensure structural strength. On the other hand, the brake component 400 also includes a positioning shaft, which is located at the center of the connection between the drive arm 410, brake arm 420, and balance arm 430. The positioning shaft is used to connect with the frame 700, thereby fixing the position of the brake component 400 relative to the drive wheel 100 and the driven wheel 200, thus achieving a stable operating effect.

[0072] In another possible embodiment of the invention, such as Figure 1 As shown, a counterweight wheel 220 is also provided on the driven wheel 200. In this embodiment, since the diameter of the driven wheel 200 is smaller than the diameter of the driving wheel 100, the counterweight wheel 220 can be placed on one side of the driven wheel 200 and fixedly connected to it. The counterweight wheel 220 is made of materials such as metal or wood, and its function is to increase the counterweight so that the user feels resistance when riding. In this embodiment, the counterweight wheel 220 should be concentrically set with the driven wheel 200 to ensure balanced resistance during riding. In terms of the outer wheel 210, it should be set outside the counterweight wheel 220 and fixedly connected to the counterweight wheel 220 to achieve the effect of corresponding to the adjusting member 421. It is worth noting that in this embodiment, since the counterweight wheel 220 and the driven wheel 200 are not in the same plane, while the driving wheel 100, the counterweight wheel 220 and the brake member 400 are set in the same plane on the frame 700, in actual installation, in order to make the adjusting member 421 correspond to the outer wheel 210, an extension structure should also be set on the brake arm 420 to form a correspondence.

[0073] More specifically, such as Figure 1 As shown, the diameter of the driven wheel 200 is smaller than that of the driving wheel 100. This is to ensure that the angular velocities of the driving wheel 100 and the driven wheel 200 are different, thereby achieving a better fitness effect. In this embodiment, the straight-line distance between the first wheel 411 and the second wheel 431 is greater than the diameter of the driven wheel 200. This is to ensure that the transmission belt 300 is simultaneously fitted onto the first wheel 411 and the second wheel 431 while being fitted onto the driving wheel 100 and the driven wheel 200. This ensures that when the transmission belt 300 is taut, it can exert pressure on the first wheel 411, thus ensuring the stable operation of the brake 400.

[0074] In another possible embodiment of the invention, such as Figure 1 As shown, a crank 610 for driving the drive wheel 100 to rotate is also provided on the aforementioned drive wheel 100. For ease of pedaling, a first pedal 621 and a second pedal 622 are respectively provided at both ends of the crank 610. The crank 610 is a Z-shaped crank 610 commonly found on bicycles in the prior art. The symmetrical center of the crank 610 is fixedly connected to the drive wheel 100. Figure 3 and Figure 4 As shown, the first pedal 621 is rotatably mounted on one end of the crank 610, and the second pedal 622 is rotatably mounted on the other end of the crank 610. The first pedal 621 and the second pedal 622 are rotatably connected to the crank 610, so that the user can adjust the pedaling angle of the first pedal 621 and the second pedal 622.

[0075] Based on the above embodiments, in order to ensure the stability of the operation of the driving wheel 100 and the driven wheel 200 and reduce the probability of the transmission belt 300 falling off, a first mounting groove is provided around the outer circumference of the driving wheel 100 and a second mounting groove is provided on the outer side of the driven wheel 200 in this embodiment. The first and second mounting grooves are not shown in the figure. Those skilled in the art can understand the structural style of setting grooves on the driving wheel 100 and the driven wheel 200 to fix the transmission belt 300, which will not be described in detail here. It is worth noting that, unlike the prior art, in this embodiment, groove structures can also be provided on the first wheel 411 and the second wheel 431 to cooperate with the transmission belt 300, so as to further improve the operational stability of the mild braking structure of the exercise bike.

[0076] Based on the above embodiments, the usage process of the mild braking structure of the exercise bike of the present invention is as follows:

[0077] When not in use, the mild braking mechanism of a stationary bike is in the following state: Figure 2 As shown, in this state, the reset member 500 is in a normal extended state, and the adjusting member 421 and the outer wheel 210 approach each other under the action of magnetic force and the pressure of the reset member 500.

[0078] When the mild braking mechanism of a stationary bike is used, such as Figure 1 As shown, when the user steps on the first pedal 621 and the second pedal 622 counterclockwise, the upper side of the transmission belt 300 is taut, which presses down on the drive arm 410. The brake 400 rotates counterclockwise as a whole, and the brake arm 420 rises to press the reset member 500. The reset member 500 accumulates elastic potential energy. At the same time, the adjusting member 421 separates from the outer wheel 210. In this state, the user can ride the exercise bike. Due to the presence of the first wheel 411 and the second wheel 431, the brake 400 does not affect the transmission process of the drive wheel 100 and the driven wheel 200.

[0079] When a user stops riding in an emergency, such as Figure 2 As shown, the driven wheel 200 is the main driving component. In this state, the lower side of the transmission belt 300 is taut and the upper side is slack. Under the elastic restoring force of the reset component 500, the brake component 400 rotates clockwise to reset. At the same time, under the magnetic force of the adjusting component 421, it moves closer to the outer wheel 210. Through the electromagnetic damping principle, the speed of the driven wheel 200 drops rapidly, thereby preventing the user from being injured by the pedal when leaving the frame 700.

[0080] In other possible embodiments of the present invention, the positional relationship between the adjusting member 421 and the outer wheel 210 can also be set to abut against each other. The advantage of this setting is that, in addition to braking the driven wheel 200 through the electromagnetic damping principle, braking can also be achieved through the frictional force of the adjusting member 421.

[0081] Based on the aforementioned mild braking structure of the exercise bike, the present invention also provides a mild braking method for the exercise bike, which is as follows: Figure 1 As shown, it includes:

[0082] S100, Obtain the transmission pressure of the transmission belt on the brake component;

[0083] Obtain the reset pressure of the reset component on the braking component;

[0084] The distance between the adjusting member on the brake and the driven wheel is adjusted according to the transmission pressure and the reset pressure.

[0085] S200: Obtain the pressing pressure value of the transmission belt on the brake component, and obtain the riding status signal based on the pressing pressure value;

[0086] S300: Control the adjusting member to apply gentle braking to the driven wheel according to the riding status signal.

[0087] In the above embodiments, the structure corresponding to the exercise bike mild braking method of the present invention should have a braking component, which is used to achieve mild braking of the driven wheel. This process is achieved by an adjusting component set on the braking component and electromagnetic damping or friction with the driven wheel. In order to enable the exercise bike to automatically distinguish the positional relationship between the adjusting component and the driven wheel in the use state and the braking state, in this embodiment, the transmission pressure of the transmission belt on the braking component and the reset pressure of the reset component on the braking component are obtained. The use state of the exercise bike is determined according to the comparison relationship between the transmission pressure and the braking pressure, thereby achieving the effect of autonomously adjusting the distance between the adjusting component and the driven wheel.

[0088] Furthermore, to achieve a more intelligent and gentle braking effect, this embodiment also simultaneously monitors the pressure value of the transmission belt on the brake component. Due to the presence of the reset component, the pressure of the transmission belt on the brake component varies when the user applies different force to the driving wheel. At the same time, the displacement of the brake component causes different rebound forces generated by the reset component on the brake component. Therefore, the pressure value of the transmission belt on the brake component also varies under different pedaling forces. Thus, by obtaining the pressure value of the transmission belt on the brake component, the actual usage state of the exercise bike can be determined, and then fed back to the adjustment component as a riding status signal. The riding status signal can further change the mode of gentle braking of the driven wheel by the adjustment component. For example, the riding status signal can be used to adjust the magnetic force of the adjustment component itself to increase the electromagnetic damping phenomenon with the driven wheel, thereby achieving intelligent gentle braking.

[0089] In the above embodiments, adjusting the distance between the adjusting member on the brake member and the driven wheel according to the transmission pressure and the combined pressure includes:

[0090] S110. Compare the transmission pressure and the reset pressure;

[0091] S120. When the transmission pressure is greater than or equal to the reset pressure, control the adjusting member to move away from the driven wheel;

[0092] S130. When the transmission pressure is less than the reset pressure, control the adjusting member to fit against the driven wheel.

[0093] In this embodiment, the relationship between the transmission pressure and the reset pressure directly affects the distance between the adjusting member and the driven wheel. In a specific embodiment, such as... Figure 1 and Figure 2 As shown, the positional relationship between the drive arm and the brake arm on the brake component is like a seesaw. When the transmission pressure is greater than or equal to the reset pressure, the brake component rotates counterclockwise, that is, the adjusting component separates from the driven wheel. In this state, the positional change is necessarily caused by the pressure applied to the drive arm by the transmission belt. In other words, the exercise bike must be in a riding state in this state. Therefore, under the drive of the structure, the adjusting component is controlled to move away from the driven wheel to avoid affecting the normal use of the exercise bike.

[0094] When the transmission pressure is less than the reset pressure, the brake component resets clockwise under the elastic action of the reset component, meaning the adjusting component moves closer to the driven wheel. In this state, it indicates that the force applied by the user to the driving wheel is too small. Therefore, the reset component takes the initiative, causing the adjusting component to reset and hindering the rotation of the driven wheel through electromagnetic damping, thereby achieving a gentle braking effect.

[0095] On the other hand, the above-mentioned method of obtaining the pressing pressure value of the transmission belt on the brake element and obtaining the riding status signal based on the pressing pressure value includes:

[0096] S210. Obtain the pressing pressure value of the transmission belt on the brake component;

[0097] S220. Compare the pressing pressure value with a first threshold;

[0098] S230. When the pressing pressure value is less than the first threshold, a first riding status signal is generated, and the first riding status signal is used to indicate that the adjustment component is activated.

[0099] S240. When the pressing pressure value is greater than or equal to the first threshold, a second riding status signal is generated, which is used to indicate that the adjustment component is deactivated.

[0100] In this embodiment, to achieve a better braking effect, the adjusting component can be configured in various ways. For example, in one specific embodiment, the adjusting component includes an electromagnet, which can achieve a mild braking effect by changing the magnetic force of the electromagnet according to the riding condition signal. Or in another specific embodiment, the above-mentioned braking component and the driven wheel can also be connected in contact. In this embodiment, the adjusting component includes other structures that can increase friction, such as a mechanical clamping structure, a mechanical supercharging structure, etc., which work together with the friction to brake the driven wheel. By controlling the above structure according to the riding condition signal, the experience during the braking process can be improved.

[0101] In this embodiment, by obtaining the pressing pressure value of the transmission belt on the brake component, the actual movement of the transmission belt can be obtained. By the magnitude of the pressing pressure value, it can be distinguished whether the exercise bike is in riding mode, spinning mode, or stopped mode. When specifically determining different states, a first threshold can be introduced, which is a certain rated pressure value. By comparing the pressing pressure value with the first threshold, the different states of the exercise bike can be distinguished.

[0102] In this embodiment, when the pressing pressure value is less than the first threshold, it indicates that the exercise bike is in a rotating state or a stopped state. In this state, a first riding state signal is generated. This first riding state signal is used to indicate the current riding state. Since the driven wheel should be braked in this state, in actual settings, the first riding state signal can be used to indicate the activation of the adjustment component to achieve a better gentle braking effect.

[0103] When the pressing pressure value is greater than the first threshold, it indicates that the exercise bike is in riding mode. In this mode, a second riding status signal is generated. This second riding status signal is the same as the first riding status signal and is used to indicate the current riding status. The difference is that under the second riding status signal, the adjustment component should not cause any obstruction to the rotation of the driven wheel, so as to avoid causing a bad experience for the user riding the exercise bike. Therefore, in this embodiment, the second riding status signal indicates that the adjustment component is deactivated.

[0104] Based on the above embodiments, in order to further determine the details of the user's riding status and thus enable the adjuster to have a more detailed dynamic adjustment function, in this embodiment, when the pressing pressure value is less than the first threshold, a first riding status signal is generated, and the first riding status signal is used to indicate the activation of the adjuster, which further includes:

[0105] S231. Obtain the speed data of the drive wheel per unit time, and record the speed data continuously per unit time.

[0106] S232. When the absolute value of the change in speed data in adjacent unit time is greater than the second threshold and the change in speed data is negative, a first control signal is generated and added to the first riding state signal.

[0107] S233. When the absolute value of the change in speed data in adjacent time periods is less than or equal to the second threshold, a second control signal is generated and added to the first riding state signal.

[0108] The first control signal and the second control signal are used to control the braking force of the adjusting element.

[0109] In this embodiment, since the pressing pressure value is less than the first threshold, it indicates that the user is not applying force to ride. Therefore, in this case, mild braking should be initiated to assist in deceleration. However, the deceleration process should not be too abrupt. Therefore, in order to achieve further mild braking, this application also records the speed data of the drive wheel and records the speed data in a continuous unit time to judge the user's movement trend, so as to serve as the basis for activating mild braking in different states.

[0110] When recording speed data in real time for consecutive units of time, this speed data can be fed back to the intelligent interrupt for recording the user's movement status. It can also judge the changes in speed data in adjacent units of time. When the absolute value of the change in adjacent speed data is greater than the second threshold, and the change in speed data is negative (current speed value - previous unit speed value = change in speed data), it indicates that the speed of the drive wheel has suddenly decreased. It is judged that the user intends to stop using the exercise bike. When this situation is detected, a first control signal can be generated and added to the first riding status signal, so as to make targeted adjustments to the braking force (including electromagnetic resistance and / or friction) of the adjustment components in this situation.

[0111] Another scenario is when the absolute value of the change in adjacent speed data is less than or equal to the second threshold, and the change in speed data is negative, indicating that the speed of the drive wheel has decreased slightly. This situation may include the user actively slowing down but continuing to use the exercise bike, or having the intention to stop using the exercise bike. When this situation is detected, a second control signal is generated and added to the first riding status signal, thereby making targeted adjustments to the braking force (including electromagnetic resistance and / or friction) of the adjustment components in this situation to prepare for the user's sudden braking.

[0112] Furthermore, based on the above embodiments, controlling the adjustment mechanism to apply gentle braking to the driven wheel according to the riding status signal includes:

[0113] S310. Analyze the riding status signal;

[0114] S320. When the riding state signal is a first riding state signal and includes a first control signal, the magnetism of the electromagnet on the adjusting member is adjusted to the maximum value.

[0115] S330. When the riding state signal is a first riding state signal and includes a second control signal, the magnetism of the electromagnet on the adjusting member is adjusted to a preset value.

[0116] S340. When the riding state signal is the second riding state signal, adjust the magnetism of the electromagnet on the adjusting member to 0.

[0117] In a specific implementation of this embodiment, the adjusting member includes an electromagnet. By controlling the magnetism of the electromagnet installed on the adjusting member, the rotating driven wheel can be affected. Even when the driven wheel is not in contact with the adjusting member, the driven wheel can still be affected.

[0118] Specifically, after analyzing the riding status signal, there are two types of riding status signals: a first riding status signal and a second riding status signal. The first riding status signal indicates that the exercise bike needs to be braked gently. Based on the above subdivision of the user's riding status, when the first riding status includes a first control signal, that is, when the drive wheel suddenly slows down, since this situation may correspond to the user stopping the bike urgently, the magnetism of the electromagnet on the adjustment component is adjusted to the maximum value, so that the adjustment component intervenes in the driven wheel. Under the action of magnetism and the reset component, the auxiliary adjustment component and the driven wheel quickly approach each other, realizing gentle braking through electromagnetic resistance and / or friction, thereby avoiding injury to the user who leaves the pedal due to high-speed pedal movement.

[0119] When the first riding state mentioned above includes the second control signal, it corresponds to a relatively gentle deceleration of the driving wheel. In this case, the user may need to stop using the vehicle. Therefore, the magnetism of the electromagnet on the adjusting component is adjusted to a preset value. In this case, intervention can be formed on the driven wheel without friction with the driven wheel, which makes it easy for the user to accelerate again or brake when stopping the vehicle.

[0120] When the above riding state is the second riding state signal, it means that the user is using the exercise bike continuously or the drive wheel of the exercise bike has stopped turning. In this case, the magnetism of the electromagnet on the adjustment part is adjusted to 0, that is, the electromagnet no longer interferes with the driven wheel, which can save energy.

[0121] In summary, this invention provides a mild braking structure and method for a stationary bicycle. The mild braking structure includes: a frame with a driving wheel and a driven wheel connected by a transmission belt; an outer wheel, which is a magnetic component, located on the outer side of the driven wheel; a braking element rotatably mounted on the frame corresponding to the inner side of the transmission belt; a driving arm that rolls against the inner side of the transmission belt; a braking arm with an adjusting component at its end, corresponding to the outer wheel; and a reset element fixedly mounted on the frame and elastically connected to the braking arm. This invention utilizes a rotating brake on the frame. The drive arm of the brake rolls against the inner side of the transmission belt, and the adjusting component on the brake arm frictionally engages with the outer wheel. When the user applies force to the drive wheel, the drive arm is pressed down by the transmission belt, and the adjusting component moves away from the outer wheel. When the force is stopped, the brake is reset by the action of the reset component, causing the adjusting component to generate electromagnetic resistance and / or friction between the outer wheel, thereby achieving the effect of rapidly reducing the speed of the driven wheel and reducing the risk of injury to the user.

[0122] It should be understood that the application of the present invention is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
