The structure of the pedal and the counterweight flywheel is similar to that of the bicycle, and the transmission is carried out through the crawler belt. However, a problem with this structure is that when the user performs an emergency stop During operation, the pedal will still rotate rapidly under the drive of the rotational inertia of the counterweight flywheel, and there is a hidden danger of causing trauma to the user's feet.

Based on the above problems in the prior art, the present invention provides a gentle braking structure for a spinning bicycle.

When applying force to the driving wheel 100, the driving arm 410 is pressed down by the transmission belt 300, and the adjusting member 421 is separated from the outer wheel 210. When the application of force is stopped, the braking member 400 is reset under the action of the reset member 500, so that the adjusting member 421 and the outer wheel 210 are separated by electromagnetic force. The damping principle allows the driven wheel 200 to moderate the effect of braking and reduce the risk of trauma to the user.

In the foregoing embodiment, as shown in FIG. 1 , the main body of the relaxation brake structure of the spinning bicycle of the present invention is composed of a frame body 700, a driving wheel 100, a driven wheel 200, a transmission belt 300 and a braking member 400, wherein the frame body 700 As shown in FIG. 4 , those skilled in the art can understand that the function of the frame body 700 is to fix the positions of the driving wheel 100 , the driven wheel 200 and the braking member 400 , and its specific shape is not limited in this application.

The driving wheel 100 and the driven wheel 200 are arranged in the same horizontal plane, and the outer sides of the driving wheel 100 and the driven wheel 200 are covered with a transmission belt 300. The transmission belt 300 is a flexible transmission belt 300, and is made of a material with a larger coefficient of friction, for example Rubber, etc., to avoid slipping. In actual use, the user can realize the effect of driving the driven wheel 200 to rotate by driving the driving wheel 100. Since the position of the frame body 700 is fixed, it can realize the effect of simulating riding on the spot to realize exercise. related needs.

The brake member 400 is used to moderately brake the driven wheel 200, the brake member 400 is arranged between the driving wheel 100 and the driven wheel 200, and is located inside the surrounding area of the transmission belt 300, those skilled in the art can understand that , the spinning bicycle in the prior art is to increase the counterweight to the driven wheel 200 to realize the effect of simulating riding resistance, but this also causes the driven wheel 200 to still be affected by the Its rotational inertia maintains high-speed rotation and drives the driving wheel 100 to rotate, so it is easy to cause trauma to the user's feet. Therefore, in this embodiment, a braking member 400 is provided to achieve gentle braking. Specifically, on the outer side of the above-mentioned driven wheel 200 An outer wheel 210 is provided, and the outer wheel 210 is fixedly connected with the driven wheel 200. Specifically, the outer wheel 210 is made of a conductive primary magnet material, such as iron, which can be attracted by a permanent magnet.

In actual use, the user usually drives the driving wheel 100 counterclockwise, and the rotation of the driving wheel 100 drives the The driven wheel 200 rotates, and the transmission belt 300 above is in a tense state at this time. Therefore, in this embodiment, the driving arm 410 is set towards the upper side of the transmission belt 300, and the balance arm 430 is set towards the lower side of the transmission belt 300, thereby realizing The drive belt 300 produces a downward force effect on the driving arm 410 during the riding process of the user.

In a possible implementation, a pressure sensor 412 is also provided at the position corresponding to the first rotating wheel 411 on the driving arm 410, and the pressure sensor 412 is used to detect the pressure exerted by the transmission belt 300 on the driving arm 410, so that the The pressure monitors the riding state of the spinning bicycle and the strength of the user's pedaling force.

Cooperate to further improve the running stability of the relaxation braking structure of the spinning bicycle.

Based on the above-mentioned embodiments, the use process of the relaxation braking structure of the spinning bicycle of the present invention is as follows:

When the easing braking structure of the spinning bicycle is not in use, its state is shown in Figure 2. In this state, the reset member 500 is in a normal extended state, and the adjustment member 421 and the outer wheel 210 are under the action of the magnetic force and the pressure of the reset member 500. close to each other

When the relaxation braking structure of the spinning bicycle is in use, as shown in Figure 1, the user steps on the first pedal 621 and the second pedal 622 counterclockwise along the diagram, and at this moment the upper side of the transmission belt 300 is in a tight state, and the driving arm 410 Forming a downward pressure, the brake part 400 rotates counterclockwise as a whole, the brake arm 420 rises to press the reset part 500, and the reset part 500 accumulates elastic potential energy. At the same time, the adjustment part 421 is separated from the outer wheel 210. In this state, the user can When riding a spinning bicycle, due to the existence of the first rotating wheel 411 and the second rotating wheel 431 , the braking member 400 does not affect the transmission process of the driving wheel 100 and the driven wheel 200 .

When the user stops riding in an emergency, as shown in FIG. 2 , the driven wheel 200 mainly plays a driving role. In this state, the lower side of the transmission belt 300 is tight and the upper side is loose. Under the action, the brake part 400 rotates clockwise to reset as a whole, and at the same time, under the magnetic force of the adjustment part 421, it approaches the outer wheel 210, and the speed of the driven wheel 200 decreases rapidly through the principle of electromagnetic damping, thereby preventing the user from being caught when leaving the frame body 700. Pedal trauma.

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. The friction force of part 421 is used for braking.

Based on the gentle braking structure of the above-mentioned spinning bicycle, the present invention also provides a gentle braking method for a spinning bicycle, as shown in Figure 1, including:

S100. Obtain the transmission pressure of the transmission belt on the brake part;

Obtain the reset pressure of the reset member on the brake member;

S200. Obtain a pressing pressure value of the transmission belt on the braking member, and obtain a riding state signal according to the pressing pressure value;

S300. Control the adjusting member to moderately brake the driven wheel according to the riding state signal.

In the above-mentioned embodiments, the structure corresponding to the gentle braking method of the spinning bicycle of the present invention should have a braking member, which is used to realize the gentle braking of the driven wheel, and the process is through setting on the braking member The electromagnetic damping or friction between the adjusting part and the driven wheel on the wheel is realized. In order to make the spinning bicycle automatically distinguish the positional relationship between the adjusting part and the driven wheel in the use state and the braking state, in this embodiment, the transmission of the transmission belt to the brake part is obtained. pressure, and obtain the reset pressure of the reset part on the brake part, and judge the use status of the spinning bike according to the comparison between the transmission pressure and the brake pressure, so as to realize the effect of independently adjusting the distance between the adjustment part and the driven wheel.

Further, in order to achieve a more intelligent easing braking effect, in this embodiment, the pressing pressure value of the transmission belt on the braking member is also monitored synchronously. At different times, the pressure of the transmission belt on the brake parts is different. At the same time, due to the displacement of the brake parts, the rebound force of the reset part on the brake parts is different. Different, so by obtaining the pressing pressure value of the transmission belt on the brake part, the actual use state of the spinning bicycle can be determined, and then fed back to the adjustment part in the form of a riding state signal, and the adjustment part can further change the relaxation of the driven wheel through the riding state signal. In the mode of braking, for example, the magnetic force of the adjusting part itself is adjusted through the riding state signal to increase the electromagnetic damping phenomenon with the driven wheel, so as to perform intelligent and easing braking.

In a specific embodiment, as shown in Figure 1 and Figure 2, the driving arm and the braking force The position relationship of the arm is like a seesaw. When the transmission pressure is greater than or equal to the reset pressure, the brake part rotates counterclockwise, that is, the adjustment part is separated from the driven wheel. In this state, it must be caused by the pressure on the drive arm given by the transmission belt. The position changes, that is, the spinning bike must be in the riding state in this state, so the adjusting part is controlled to be away from the driven wheel under the drive of the structure, so as to avoid affecting the normal use of the spinning bike.

When the transmission pressure is lower than the reset pressure, the brake part resets clockwise under the elastic action of the reset part, that is, the adjustment part is close to the driven wheel. In this state, it means that the force applied by the user to the driving wheel is too small, so the reset part Take the initiative to reset the adjusting part, and hinder the rotation of the driven wheel through electromagnetic damping, so as to achieve the effect of easing braking.

On the other hand, the acquisition of the pressing pressure value of the transmission belt on the brake piece, and the acquisition of the riding state signal according to the pressing pressure value include:

S210. Obtain the pressing pressure value of the transmission belt on the braking member;

S220. Comparing the pressing pressure value with a first threshold;

S230. When the pressing pressure value is less than a first threshold, generate a first riding state signal, where the first riding state signal is used to indicate that the adjustment member is activated;

S240. When the pressing pressure value is greater than or equal to the first threshold, generate a second riding state signal, where the second riding state signal is used to indicate that the adjustment member is disabled.

In this embodiment, in order to obtain a better braking effect, the adjustment member can be set in various types in this embodiment. For example, in a specific embodiment, the adjustment member includes an electromagnet, which can Change the magnetic force of the electromagnet, so as to achieve the effect of easing the braking, or in another specific embodiment, the above-mentioned braking member and the driven wheel can also be connected in abutment. In this embodiment, the adjusting member includes other components that can increase the frictional force The structure, such as mechanical clamping structure, supercharged structure, etc., cooperates with the friction brake driven wheel, and the above structure is controlled according to the riding condition signal to improve the experience in the braking process.

In this embodiment, the actual motion of the transmission belt can be obtained by obtaining the pressing pressure value of the transmission belt on the brake parts. Through the size of the pressing pressure value, it can be distinguished whether the spinning bicycle is in a riding state, an autorotation state or a stopped state. Specifically, when judging different states, a first threshold can be introduced. The first threshold is a certain rated pressure value. By comparing the pressing pressure value with the first threshold, different states of the spinning bike can be distinguished.

In this embodiment, when the pressing pressure value is less than the first threshold value, it means that the spinning bike is in the autorotation state or the stop state at this time. In this state, the first riding state signal is generated, and the first riding state signal is used for Indicates the current riding state, since the driven wheel should be braked in this state, so in actual setting, the first riding state signal can be used to indicate the activation of the adjustment member, so as to achieve a better easing braking effect.

When the pressing pressure value is greater than the first threshold value, it indicates that the spinning bicycle is in the riding state at this time, and in this state, a second riding state signal is generated, which is the same as the first riding state signal, and is used to Unlike indicating the current riding state, the difference is that under the second riding state signal, the adjusting member should not cause any obstacle to the rotation of the driven wheel, so as to avoid causing a bad experience to the user when riding the spinning bike. Therefore, in this In an embodiment the second ride state signal indicates that the adjustment is deactivated.

Based on the above embodiment, in order to further judge the details of the user's riding state, so that the regulator has a more detailed dynamic adjustment function, in this embodiment, when the pressing pressure value is less than the first threshold , generating a first riding state signal, the first riding state signal being used to indicate that the adjustment member is started further includes:

S231. Obtain the speed data of the driving wheel within a unit time, and record the speed data within a continuous unit time;

S232. When the absolute value of the change amount of the speed data in an adjacent unit time is greater than the second threshold and the change amount of the speed data is a negative value, generate a first control signal, and send the first control signal to added to the first riding state signal;

S233. When the absolute value of the variation of the speed data at adjacent times is less than or equal to a second threshold, generate a second control signal, and add the second control signal to the first riding state signal ;

The first control signal and the second control signal are used to control the braking force of the regulating member.

In this embodiment, since the above-mentioned pressing pressure value is less than the first threshold, it means that the user is not exerting force to ride, so in this case, soft braking should be started to assist deceleration, but it should not be too aggressive for the deceleration process Therefore, in order to achieve further easing braking, this application also records the speed data of the driving wheel and records the speed data in a continuous unit of time to judge the user's movement trend as a different state of easing braking. basis for opening.

When the speed data of the continuous unit time is recorded in real time, the speed data can be fed back to the intelligent interrupt to record the user's exercise state, and the change of the speed data of the adjacent unit time can also be judged. When the absolute value of the variation of the adjacent speed data is greater than the second threshold, and when the variation of the speed data is a negative value (the current speed value-the speed value of the previous unit=the variation of the speed data), the speed of the driving wheel is explained. For a sudden decrease, it is judged that the user has the intention to stop using the spinning bicycle at this time. When this situation is detected, the first control signal can be generated and added to the first riding state signal, so as to address this In this case, the braking force (including electromagnetic resistance and/or friction force) of the adjusting member is adjusted in a targeted manner.

Another situation is that when the absolute value of the variation of adjacent speed data is less than or equal to the second threshold and the variation of the speed data is a negative value, it means that the speed of the driving wheel has decreased slightly. This situation may It includes the user's active deceleration but continues to use the spinning bike, or has the intention to stop using the spinning bike. When this situation is detected, a second control signal is generated and the second control signal is added to the first riding state signal. Therefore, for this situation, the braking force (including electromagnetic resistance and/or friction) of the adjusting member is adjusted in a targeted manner, so as to prepare for sudden braking by the user.

Further, based on the above-mentioned embodiment, controlling the adjusting member to moderately brake the driven wheel according to the riding state signal includes:

S310. Analyzing the riding state signal;

S320. When the riding state signal is the first riding state signal and includes the first control signal, adjust the magnetism of the electromagnet on the adjusting member to a maximum value;

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

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

In a specific implementable manner of this embodiment, the above-mentioned adjusting member includes an electromagnet, and by controlling the magnetism of the electromagnet disposed on the adjusting member, the rotating driven wheel can be influenced, even when the driven wheel is not in contact with the adjusting member. In some cases, it can also affect the driven wheel.

Specifically, after analyzing the riding state signal, the riding state signal specifically has two situations: the first riding state signal and the second riding state signal, wherein the first riding state signal indicates that the spinning bicycle needs to be relaxed. Braking, based on the above-mentioned subdivision of the user's riding state, when the above-mentioned first riding state contains the first control signal, that is, when the driving wheel suddenly slows down, since this situation may correspond to the user's emergency stop, so The magnetism of the electromagnet on the adjusting part is adjusted to the maximum value, so that the adjusting part intervenes in the driven wheel. Under the action of the magnetism and the reset part, the auxiliary adjusting part and the driven wheel are quickly approached to realize the electromagnetic resistance and/or friction Eases the braking, thereby avoiding trauma to the user who is off the pedal due to high speed pedal movement.

When the above-mentioned first riding state includes the second control signal, it corresponds to a relatively gentle deceleration of the driving wheel. In this case, the user may stop using it, so the magnetism of the electromagnet on the adjustment member is adjusted to a preset value. In this case, the intervention on the driven wheel can be formed without friction with the driven wheel, which is convenient for the user to re-accelerate or brake when stopping use.

When the above-mentioned riding state is the second riding state signal, it means that the user is using the spinning bike continuously or the driving wheel of the spinning bike is stopped. In this case, adjust the magnetism of the electromagnet on the adjusting part to 0, that is, no more intervention on the driven wheel through the electromagnet, and it can save electric energy.
