Description

Technical Field

[0001] The utility model relates to the field of cycling platforms, in particular to a roller cycling platform. Background Art

[0002] Cycling platform is a device that allows users to perform cycling training indoors. When using it, users match and connect the bicycle to the cycling platform and then experience cycling. It is simple and quick to assemble with the bicycle; it is not affected by the environment; it is easy to use and has many advantages. It is deeply loved by some cycling and fitness users.

[0003] There are damping structures on the market that use magnetism, liquid, or air to create resistance, simulating the effects of outdoor cycling. However, these damping structures can only simulate the resistance of uphill riding, and cannot simulate the inertia of downhill and flat-road riding. The wheels quickly stop rotating when the rider stops pedaling. Riders not only need to experience the strenuous climb, but also the relaxing feeling of accelerating downhill, which is the joy of riding. However, when users use roller bikes, the damping structure can only simulate uphill riding, not the joy of downhill riding. This fails to truly simulate outdoor cycling, making the bikes merely a boring training tool, depriving users of the same joy as outdoor cycling. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1-4 shown.

[0034] A roller riding platform, characterized by at least comprising:

[0035] Bracket 8, used to fix the bicycle;

[0036] The roller 1 is rotatably mounted on the bracket 8 and is in frictional contact with the wheel;

[0037] The motor 2 is fixedly connected to the bracket 8, and the rotating shaft 21 of the motor 2 is coaxially connected to the roller 1 to drive the roller 1 to rotate;

[0038] a controller 3, electrically connected to the motor 2 and to an external power source 9, forming a drive circuit;

[0039] The external power supply 9 provides power to the motor 2, and the controller 3 controls the direction of rotation of the motor;

[0040] A control switch 23 is provided between the external power source 9 and the motor 2 .

[0041] Common roller-type and fixed roller trainers currently on the market often use resistance devices such as fluid, magnetic, or electrical resistance to generate resistance. These are inexpensive and require no disassembly of the bicycle's rear wheel for assembly, making them convenient to use. However, these roller trainers constantly generate resistance, and the bicycle quickly stops when the user stops pedaling. This means that these roller trainers only simulate uphill riding, not downhill or flat roads. Consequently, they fail to provide the user with the sensation of cycling outdoors, resulting in a poor user experience.

[0042] The present invention provides a bicycle platform comprising at least one embodiment of the present invention: a bicycle secured by a bracket 8 such that the rear wheel of the bicycle is in close contact with a roller 1. A motor 2, wherein a rotating shaft 21 of the motor 2 is connected to the roller 1, drives the roller 1 to rotate, generating friction with the wheel. During riding, the wheel has a first rotational direction. When the motor 2 drives the roller 1 to rotate in a direction opposite to the first rotational direction, the roller 1 rotates in the opposite direction of the wheel, similar to a gear transmission. The roller 1 applies tangential force to the rear wheel at the contact surface between the two, thereby simulating the inertia generated during downhill riding. When the motor 2 drives the roller 1 to rotate in the same direction as the first rotational direction, the roller 1 rotates in the same direction as the wheel, and the roller 1 applies tangential resistance to the rear wheel at the contact surface between the two, thereby simulating the resistance generated during uphill riding. Therefore, the present invention can simulate the resistance generated during uphill riding, and can also simulate the power generated during downhill riding, thereby achieving a more realistic riding experience.

[0043] Among them, the rotation direction of the motor 2 shaft 21 is related to the current direction and the magnetic field direction. In the prior art, the motor 2 is generally divided into a DC motor 2 and an AC motor 2. When the motor 2 in the present invention is a DC motor 2, the DC motor 2 can be turned by assembling the inverter and other structures on the controller 3; when the motor 2 in the present invention is an AC motor 2, the forward and reverse switch is set on the controller 3 to adjust the direction of the motor 2.

[0044] In this embodiment, the rotation direction of the motor 2 is switched by the controller 3 to change the force exerted on the wheel by the roller 1, allowing the user to experience both uphill and downhill riding, making the riding platform more realistically simulate outdoor riding and improving the user's experience. The external power supply 9 is manually controlled to supply power to the motor 2 by turning on the control switch 23 or setting the control switch 23 to a button.

[0045] Example 2

[0046] The controller 3 is further provided with an adjustment unit 31 . The adjustment unit 31 is arranged in the driving circuit and is used to adjust the current or voltage in the driving circuit.

[0047] During outdoor riding, the road conditions are sometimes uphill and sometimes downhill, and the magnitude of the ups and downslopes is constantly changing. To better simulate outdoor riding, the riding platform not only needs to have an applied force in both uphill and downhill directions, but also needs to change the magnitude of the applied force from time to time. Therefore, the controller 3 in this embodiment is also provided with an adjustment unit 31 for adjusting the speed of the motor 2. The AC external power supply 9 is converted to a DC external power supply 9, and the voltage and current are adjusted to control the speed of the motor 2, thereby simulating the slope of different scenarios. Different uphill slopes are obtained by adjusting the size of the damping coefficient of the motor 2, and different downhill slopes are obtained by adjusting the rotor speed.

[0048] Specifically, for example, the adjustment unit 31 usually adopts an adjustable resistor, which is connected in series with the drive circuit. The current passing through the motor 2 is adjusted by adjusting the resistance value of the adjustable resistor, thereby realizing the control of the speed of the motor 2, and ultimately controlling the power / resistance applied by the rotating shaft 21 of the motor 2 to the rear wheel of the bicycle. Under the action of the controller 3 and the adjustment unit 31, the size and direction of the motor 2 can be adjusted at the same time.

[0049] Example 3

[0050] The inertia wheel 4 is coaxially connected to the roller 1 , and the radius of the inertia wheel 4 is greater than the radius of the roller 1 , and the weight of the inertia wheel 4 is greater than 2 kg.

[0051] During a real ride, even after the rider stops pedaling, the bicycle continues to move forward due to inertia. The kinetic energy generated at this point is based on the rider's weight and the bicycle's combined mass multiplied by the speed. Larger masses generate greater kinetic energy, thus overcoming resistance such as wind resistance and wheel resistance, allowing the bicycle to travel significant distances. However, in a cycling platform, the combined mass of rollers 1 and wheels (when external power supply 9 is disconnected) is very small, resulting in minimal kinetic energy. Therefore, after stopping pedaling on the platform, this kinetic energy is insufficient to overcome the electromagnetic resistance of motor 2, causing the wheels to quickly stop rotating, failing to effectively simulate the feeling of a real outdoor ride.

[0052] In this regard, an inertia wheel 4 is added in this embodiment and fixedly connected to the roller 1, and rotates synchronously with the roller 1. The radius of the inertia wheel 4 is at least greater than the radius of the roller 1. The inertia wheel 4 having a radius greater than that of the roller 1 can generate centrifugal force during rotation. Centrifugal force is a kind of inertial force. The magnitude of the centrifugal force can be increased by increasing the diameter and weight of the inertia wheel 4. Therefore, in this embodiment, the centrifugal force generated by the inertia wheel 4 is used to overcome the internal resistance of the motor 2, thereby simulating the state of stopping pedaling and using inertia to slide during outdoor riding, thereby improving the user's riding experience.

[0053] Example 4

[0054] like Figure 3 、 Figure 4 shown.

[0055] The energy storage unit 5 includes a charging terminal and a discharging terminal, wherein the charging terminal of the energy storage unit 5 is electrically connected to the motor 2; the charging terminal of the energy storage unit 5 is electrically connected to the external power supply 9;

[0056] Wherein, a switch 32 is provided between the energy storage unit 5 and the external power supply 9;

[0057] The control switch 23 is a single-pole double-throw switch for controlling the connection between the motor 2 and the external power supply 9 or the energy storage unit 5 .

[0058] When a user cycles, chemical energy in the human body is converted into kinetic energy. While cycling outdoors, this kinetic energy is used to propel the bike forward. However, when riding on a cycling platform, this kinetic energy is converted into heat by friction and released into the air. This heat is effectively wasted energy. For the average cyclist, an hour of cycling can generate over 200 kilowatts of energy. In the long run, this is a huge waste of energy.

[0059] In this regard, this embodiment also includes an energy storage unit 5 and a switching switch 32. The lead of the motor 2 is electrically connected to the charging end of the energy storage unit 5; the charging end of the energy storage unit 5 is electrically connected to the external power supply 9; when the switching switch 32 is closed, the external power supply 9 supplies power to the energy storage unit 5.

[0060] The control switch 23 is a single-pole double-throw switch. When the control switch 23 connects the motor 2 with the energy storage unit 5 and disconnects the motor 2 from the external power supply 9 , the motor 2 supplies power to the energy storage unit 5 .

[0061] Specifically, when external power source 9 stops supplying power to motor 2, the user can continue riding. Motor 2 acts as a generator, with the wheel driving roller 1 to rotate. Roller 1 is connected to motor 2's rotating shaft 21, which in turn is connected to motor 2's rotor. To continue riding, the user must overcome the electromagnetic resistance of the rotating rotor cutting through the magnetic induction coils, simulating riding. The coils in the rotor cut through magnetic lines of force in the magnetic field, generating electrical energy, which is stored in energy storage unit 5.

[0062] Specifically, riding on a cycling platform is safer than riding outdoors, but the environment is dull and lacks scenery. Users often open electronic devices such as tablets or mobile phones in front of the cycling platform to watch videos or play cycling games to increase the fun of indoor cycling. The energy storage unit 5 charges electronic devices such as mobile phones and tablets through the output interface of the discharge end.

[0063] Example 5

[0064] An overload protection unit 6 is included. The overload protection unit 6 is electrically connected to the controller 3 and connected in parallel with the energy storage unit 5 to form a protection circuit for consuming the electricity that the energy storage unit 5 cannot accommodate.

[0065] If the energy storage unit 5 is overcharged, causing it to heat up and reducing its service life, the controller 3 is electrically connected to the overload protection unit 6 to transmit the excess power generated to the overload protection unit 6 for consumption. Specifically, the overload protection unit 6 is configured as a heat dissipation resistor to convert the excess electrical energy into heat energy.

[0066] Example 6

[0067] It also includes a first cooling fan 11, which is coaxially connected to the roller 1 and rotates synchronously with the roller 1. The first cooling fan 11 is located between the roller 1 and the cooling resistor and blows air toward the cooling resistor.

[0068] In common heat dissipation resistor usage scenarios, after heat energy is generated, it needs to be dissipated through heat dissipation devices such as heat sinks, fans, and liquid cooling tubes. These heat dissipation devices often need to be connected to an external power source 9 to work. However, in this application, the roller 1 is in a high-speed rotation state regardless of whether the riding platform is connected to an external power source 9. Therefore, this embodiment adds a first cooling fan 11 to the end of the roller 1, so that the heat dissipation resistor can be cooled even when the riding platform is not connected to an external power source 9. Specifically, the first cooling fan 11 is located between the roller 1 and the heat dissipation resistor, blowing air toward the heat dissipation resistor, dispersing the hot air toward the outer area of ​​the device.

[0069] Example 7

[0070] The rotating shaft 21 of the motor 2 passes through both ends of the motor 2 , one end of the rotating shaft 21 is fixedly connected to the roller 1 , and the second cooling fan 22 is connected to the other end of the rotating shaft 21 .

[0071] For the motor 2, which is in a long-term working state, heat dissipation is also required. However, the difference from the heat dissipation of the heat dissipation resistor is that the heat dissipation resistor is connected to the circuit through a wire, and the specific position can be adjusted, and it has no effect on the rotation of the roller 1. Then the motor 2 and the roller 1 need to maintain coaxiality. The coaxiality is twice the maximum distance between the axis of the measured element and the reference element. That is to say, the longer the rotating shaft 21 of the motor 2 and the roller 1, the greater the coaxiality error. If a second cooling fan 22 is added between the motor 2 and the rotating shaft 21, it is necessary to increase the length of the rotating shaft 21 of the motor 2 or the roller 1, which affects the coaxiality of the two, making the roller 1 easy to shake, make abnormal noises, and bump.

[0072] In this embodiment, the rotating shaft 21 of the motor 2 extends through the motor 2. One end of the rotating shaft 21 is fixedly connected to the roller 1, and the other end is provided with a second cooling fan 22. Specifically, the second cooling fan 22 can blow air toward the motor 2, causing the hot air to flow in the first direction and ultimately dissipate the heat along with the heat from the heat dissipation resistor. Alternatively, the second cooling fan 22 can blow air away from the motor 2, drawing the hot air around the motor 2 into the second cooling fan 22 and then dissipating it toward the outside of the housing 81.

[0073] Example 8

[0074] It also includes a coupling 7 connecting the rotating shaft 21 of the motor 2 and the roller 1.

[0075] As mentioned in the previous embodiment, the coaxiality between the motor 2 shaft 21 and the roller 1 will cause the roller 1 to tilt during rotation, resulting in abnormal noise and collisions, reducing the service life of the equipment and the user experience.

[0076] In this embodiment, the motor 2 shaft 21 and the roller 1 are connected by a coupling 7. The coupling 7 is a shaft connecting component used in precision instruments. It can still realize transmission when the two shafts are in the state of different axes. The motor 2 shaft 21 and the roller 1 are connected by the coupling 7. The roller 1 is only connected to the bracket 8 through the bearing. When the motor 2 shaft 21 rotates, even if the coaxiality between the shaft 21 and the roller 1 is not enough, the coupling 7 can also automatically compensate, and the roller 1 and the shaft 21 will not interfere with each other, causing the roller 1 to tilt, shake, etc.

[0077] Example 9

[0078] The controller 3 is provided with a wireless communication module; wherein, the wireless communication module is wirelessly connected to the data terminal 91. The wireless communication module 33 is provided with a wireless communication protocol such as Bluetooth and ANT. Through the wireless communication protocol, two-way communication can be achieved with the data terminal 91, and riding data can be sent to the data terminal 91. The data terminal 91 can be any external device such as a mobile phone, a computer, or a tablet that can be connected to the controller 3. During use, the data terminal 91 can convert the information of the riding road selected in advance (slope, distance, etc.) into electronic information (current magnitude, direction, and duration) and transmit it to the controller 3. The controller 3 controls the speed, direction, and duration of the motor 2 according to the electronic information, thereby achieving riding training that simulates real road conditions.

[0080] It is understandable that in order to avoid injuries caused by the equipment, such as injuries caused by the high-speed rotating roller 1, burns caused by the heat dissipation resistor, and scratches caused by the heat dissipation fan, the bracket 8 must have a shell 81 to enclose these components.
