Description

Technical Field

[0001] The utility model relates to a bicycle training platform, in particular to a bicycle training platform which allows a user to perform bicycle riding training on an electric treadmill. Background Art

[0002] There are many types of bicycle training platforms on the market, which are mainly used for users to perform bicycle riding training indoors or in other environments with limited space, that is, to perform stationary riding exercises on a bicycle training platform using a general moving bicycle.

[0003] A commonly used bicycle training platform is similar to a treadmill, and includes an electric treadmill, for the user to place a normal moving bicycle on the electric treadmill, and ride the bicycle in place on the conveyor belt according to the running speed of the conveyor belt of the electric treadmill. This bicycle training platform usually also needs to be provided with handrails on both sides of the electric treadmill. When the user places the bicycle on the electric treadmill and rides on the bicycle, the user needs to start the electric treadmill first, and then hold the handrails to achieve balance, until the bicycle wheel reaches a certain speed and the user can achieve balance through the speed of the bicycle, the user will let go of the handrails and hold the handlebars of the bicycle instead to perform riding training.

[0004] However, although the aforementioned handrails help the user to achieve balance at the beginning of riding, they also cause obstacles and inconveniences to the user during the process of getting on and off the bicycle and riding, and make the user feel a sense of oppression when riding, so there is still room for improvement. Summary of the invention

[0005] In view of the above problems, the main purpose of the present invention is to provide a bicycle training platform, which helps the user to achieve balance and avoids obstacles, inconvenience and pressure on the user.

[0006] To achieve the above-mentioned purpose, the utility model provides a bicycle training platform, which is characterized in that it includes: an electric treadmill, including a base, a conveyor belt arranged on the base, and a driver for driving the conveyor belt to operate cyclically, the electric treadmill can define a front and a rear, and the electric treadmill allows a user to ride a bicycle on the conveyor belt toward the front; a controller, which is electrically connected to the driver of the electric treadmill and can control the operation of the driver and thus control the operating speed of the conveyor belt; an auxiliary plate, which has a pedal portion located above the conveyor belt; wherein the electric treadmill includes two wheel areas, the two wheels of the bicycle are respectively located in the two wheel areas, and the auxiliary plate is located between the two wheel areas, for the user riding on the bicycle to step on the pedal portion of the auxiliary plate.

[0007] The technical solution of the utility model further comprises a pedal switch, which is arranged on the auxiliary board and electrically connected to the controller for starting and shutting down the electric treadmill.

[0008] It also includes a sensing unit, which includes at least one swinging member and at least one sensor that can sense the swinging of the swinging member and send out a corresponding signal. The swinging member can swing back and forth across the electric treadmill so that the wheel of the bicycle pushes against the swinging member to make the swinging member swing. The sensor is electrically connected to the controller, and the controller adjusts the running speed of the conveyor belt according to the signal sent by the sensor.

[0009] The swinging member of the sensing unit includes a first swinging member and a second swinging member, and the first swinging member and the second swinging member are located in one of the wheel areas, so as to allow one of the wheels to be set between the first swinging member and the second swinging member; the sensor of the sensing unit includes a first sensor that can sense the swinging of the first swinging member and send a corresponding signal, and a second sensor that can sense the swinging of the second swinging member and send a corresponding signal.

[0010] The electric treadmill has a front end facing forward and a rear end facing rearward, and the first swinging member is closer to the front end of the electric treadmill than the second swinging member; when the first swinging member swings forward, the signal emitted by the first sensor causes the controller to increase the operating speed of the conveyor belt; when the second swinging member swings rearward, the signal emitted by the second sensor causes the controller to reduce the operating speed of the conveyor belt.

[0011] The second sensor can also sense an abnormal swinging state of the second swinging member. At this time, the signal sent by the second sensor causes the controller to control the conveyor belt to stop running.

[0012] The first swing member and the second swing member respectively include two vertical poles pivotally mounted on the base of the electric treadmill, and a cross bar arranged between the two vertical poles and spanning over the conveyor belt, so that the wheel of the bicycle pushes against the cross bar to make the two vertical poles swing simultaneously; the base of the electric treadmill is provided with a plurality of stoppers, a rear side of at least one of the vertical poles of the first swing member is adjacent to the stopper, and a front side of at least one of the vertical poles of the second swing member is adjacent to the stopper.

[0013] The first swing member and the second swing member respectively include two vertical poles pivotally mounted on the base of the electric treadmill, and a cross bar arranged between the two vertical poles and spanning over the conveyor belt, so that the wheel of the bicycle pushes against the cross bar to make the two vertical poles swing simultaneously; the base of the electric treadmill is provided with a plurality of stoppers, a rear side of at least one of the vertical poles of the first swing member is adjacent to the stopper, and a front side of at least one of the vertical poles of the second swing member is adjacent to the stopper.

[0014] The auxiliary plate is arranged on the base of the electric treadmill.

[0015] The utility model also comprises an inclined pedal, which extends upward and forward obliquely from a top surface of the auxiliary plate.

[0016] With the above technical solution, the user first places the bicycle on the electric treadmill so that the wheels of the bicycle are respectively located in the two wheel areas, and then the user rides on the bicycle and starts the electric treadmill to make the wheels of the bicycle start to rotate. During this process, the user's feet can step on the pedal part of the auxiliary plate, so the user and the bicycle can easily maintain balance, and the user's hands can first hold the handlebars of the bicycle until the wheels of the bicycle reach a certain speed, and then the user can move his feet to the pedals of the bicycle and start riding training. In other words, the bicycle training platform provided by the utility model does not need to set handrails for users to hold on both sides of the electric treadmill, but allows the user to achieve balance at the beginning of riding through the auxiliary plate, and the auxiliary plate only needs to be slightly higher than the conveyor belt, so its height position is very low and will not cause obstruction, inconvenience and oppression to the user.

[0026] The applicant first explains that in the embodiments and drawings to be introduced below, the same reference numbers represent the same or similar elements or their structural features. It should be noted that the elements and structures in the drawings are for illustration purposes only and are not drawn according to the actual proportions and quantities, and if it is possible in practice, the features of different embodiments can be applied interchangeably. Secondly, when it is mentioned that an element is disposed on another element, it means that the aforementioned element is directly disposed on the other element, or the aforementioned element is indirectly disposed on the other element, that is, one or more other elements are disposed between the two elements. When it is mentioned that an element is "directly" disposed on another element, it means that no other elements are disposed between the two elements.

[0027] Please read first Figures 1 to 3 As shown, a bicycle training platform 10 provided by a preferred embodiment of the present invention includes an electric treadmill 20, a controller 30, a sensor unit 40, an auxiliary board 12, and a pedal switch 14. The electric treadmill 20 can define a front D1 and a rear D2. When using the bicycle training platform 10, the user places the front of the bicycle 50 toward the front D1.

[0028] The electric treadmill 20 mainly includes a base 21, a conveyor belt 22, and a driver 23. The base 21 mainly includes a frame 211, a front roller 212, a rear roller 213 and a plurality of inner rollers 214 rotatably disposed in the frame 211, and a support plate 215 fixed in the frame 211. The conveyor belt 22 surrounds all the front, rear and inner rollers 212, 213, 214 and the support plate 215. The driver 23 is disposed on the frame 211 and can drive the conveyor belt 22 to circulate through a transmission device (not shown in the figure). The electric treadmill 20 in the utility model is similar to the treadmill of a conventional treadmill, but the electric treadmill 20 in the utility model is used for a user to ride a bicycle 50 on the conveyor belt 22 facing forward D1, that is, the two wheels 51 and 52 of the bicycle 50 are in contact with the surface of the conveyor belt 22, such as Figure 4 In order to simplify the diagram and facilitate the description, the diagram of the utility model only briefly shows the basic structure of the electric treadmill 20, and other mechanisms that are relatively unrelated to the technology of the present case, such as the footrest that cooperates with the base 21 to enable the base 21 to be supported off the ground, the transmission device for driving the conveyor belt 22 to operate, and the lifting mechanism for lifting the base 21 to provide an elevation climbing effect, etc., are not disclosed in detail. However, the aforementioned components are similar to those used in traditional treadmills, so those with ordinary knowledge in the relevant technical field should be able to clearly understand them.

[0029] The controller 30 has a circuit board (not shown) inside, which is electrically connected to the driver 23 of the electric treadmill 20 and can control the operation of the driver 23, thereby controlling the running speed of the conveyor belt 22. The outside of the controller 30 may include a plurality of buttons or a control panel (not shown) for the user to operate the electric treadmill 20, to turn on and off the power, and to set functions such as the elevation angle of the base 21 and the maximum speed limit of the conveyor belt 22. In order to simplify the diagram and facilitate the description, the diagram of the utility model only uses a rectangular parallelepiped to represent the controller 30.

[0030] The sensing unit 40 of this embodiment includes a first sensing device 41 and a second sensing device 42. The first sensing device 41 includes a first swinging member 411 and a first sensor 412 that can sense the swinging of the first swinging member 411 and send a corresponding signal. The second sensing device 42 includes a second swinging member 421 and a second sensor 422 that can sense the swinging of the second swinging member 421 and send a corresponding signal. The swinging members 411 and 421 are respectively arranged across the electric treadmill 20 so as to be able to swing back and forth, so that one of the wheels 51 of the bicycle 50 (the rear wheel in this embodiment) pushes against the swinging members 411 and 421 to make the swinging members 411 and 421 swing. The sensors 412 and 422 are electrically connected to the controller 30. The controller 30 adjusts the operation of the driver 23 according to the signals sent by the sensors 412 and 422, thereby adjusting the running speed of the conveyor belt 22.

[0031] In detail, the first swing member 411 includes two vertical rods 411a pivoted on the left and right sides of the base 21 of the electric treadmill 20, and a crossbar 411b disposed between the two vertical rods 411a and across the conveyor belt 22. The second swing member 421 includes two vertical rods 421a pivoted on the left and right sides of the base 21 of the electric treadmill 20, and a crossbar 421b disposed between the two vertical rods 421a and across the conveyor belt 22. The first swing member 411 is generally located in the middle section of the conveyor belt 22, and the second swing member 421 is located closer to the rear end 24 of the electric treadmill 20 than the first swing member 411, that is, the first swing member 411 is closer to the front end 25 of the electric treadmill 20 than the second swing member 421. When using the bicycle training platform 10, the user places the wheel 51 (i.e., the rear wheel) of the bicycle 50 between the first swing member 411 and the second swing member 421, and rides the bicycle 50 on the conveyor belt 22 in a manner that the wheel 51 does not contact the first and second swing members 411 and 421. Secondly, regarding the sensors 412 and 422, any sensor that can detect the swing of the swing members 411 and 421 and output a corresponding signal, such as a mechanical proximity switch, an optical induction switch, an electromagnetic sensing switch, etc., can be used, and the setting position can be (but not limited to) located at the rotation axis of the swing members 411 and 421 or near the aforementioned rotation axis.

[0032] Furthermore, the electric treadmill 20 includes two wheel regions 27 and 28, so that the wheel 51 (i.e., rear wheel) and the wheel 52 (i.e., front wheel) of the bicycle 50 are respectively located in the wheel regions 27 and 28, and the first and second swing members 411 and 421 are located in the wheel region 27. The auxiliary plate 12 is fixedly mounted on the base 21 of the electric treadmill 20, and its top surface forms a stepping portion 12a which is arranged above the conveyor belt 22 and is stepped on by the user, that is, the auxiliary plate 12 is slightly higher than the conveyor belt 22 and does not contact the conveyor belt 22, and the auxiliary plate 12 is located between the wheel regions 27 and 28, so the auxiliary plate 12 is approximately located below the pedal 53 of the bicycle 50. In addition, a stepping switch 14 can be further arranged on the auxiliary plate 12, and the stepping switch 14 is electrically connected to the controller 30 for starting and shutting down the electric treadmill 20.

[0033] Therefore, when the user wants to start using the bicycle training platform 10, the user first places the bicycle 50 on the electric treadmill 20 so that the wheels 51 and 52 of the bicycle 50 are located in the wheel areas 27 and 28, respectively. Then the user rides on the bicycle 50 and starts the electric treadmill 20 to make the wheels 51 and 52 of the bicycle 50 start to rotate. During this process, the user's feet can step on the pedal portion 12a of the auxiliary board 12, so the user and the bicycle 50 can easily maintain balance. At the same time, the user only needs to step on the pedal switch 14 to quickly, conveniently and safely start the electric treadmill 20. During the above-mentioned starting process, the user's hands can first hold the handlebars 54 of the bicycle 50 until the wheels 51 and 52 of the bicycle 50 reach a certain rotation speed, and then the user can move his feet to the pedals 53 of the bicycle 50 to start riding training.

[0034] During riding, if the riding speed of the user is roughly consistent with the running speed of the conveyor belt 22, the user can ride the bicycle 50 on the conveyor belt 22 in a nearly stationary state to perform riding training. When the user increases the riding speed, causing the speed of the bicycle 50 to be faster than the conveyor belt 22, the bicycle 50 will move forward D1 on the conveyor belt 22, and the wheel 51 will then push against the crossbar 411b of the first swinging member 411, causing the two vertical rods 411a of the first swinging member 411 to swing forward at the same time. Figure 5 As shown, at this time, the signal sent by the first sensor 412 causes the controller 30 to increase the operating speed of the conveyor belt 22 to match the current riding speed of the user, so that the bicycle 50 no longer moves forward D1, thereby preventing the bicycle 50 from rushing forward outside the bicycle training platform 10 and causing danger. In addition, by increasing the operating speed of the conveyor belt 22, the speed of the bicycle 50 and the speed of the conveyor belt 22 can be restored to a roughly consistent state. In this way, the wheel 51 (i.e., the rear wheel) of the bicycle 50 can return to the position between the first and second swinging members 411 and 421, so that the user can continue to ride on the conveyor belt 22 at the current speed in a state of being almost motionless, so as to increase the riding training intensity.

[0035] On the other hand, when the user reduces the riding speed during riding, causing the speed of the bicycle 50 to be slower than the conveyor belt 22, the bicycle 50 will move backward D2 on the conveyor belt 22, and the wheel 51 will then push against the crossbar 421b of the second swinging member 421, causing the two vertical rods 421a of the second swinging member 421 to swing backward at the same time. Figure 6As shown, at this time, the signal sent by the second sensor 422 causes the controller 30 to reduce the operating speed of the conveyor belt 22 to match the current riding speed of the user, so that the bicycle 50 no longer moves to the rear D2, thereby preventing the bicycle 50 from rushing backwards out of the bicycle training platform 10 and causing danger. In addition, reducing the operating speed of the conveyor belt 22 can restore the speed of the bicycle 50 and the speed of the conveyor belt 22 to a roughly consistent state. In this way, the wheel 51 (i.e., the rear wheel) of the bicycle 50 can return to the position between the first and second swinging members 411 and 421, so that the user can continue to ride on the conveyor belt 22 at the current speed in a state of being almost motionless, thereby reducing the riding training intensity.

[0036] In addition, during riding, when the speed of the bicycle 50 decreases suddenly, such as during emergency braking, the bicycle 50 will quickly move backward D2 on the conveyor belt 22. At this time, the second sensor 422 will sense an abnormal swing state S of the second swing member 421, such as Figure 7 As shown, for example, the second sensor 422 may be a sensor that can sense the force applied to the second swinging member 421, or a sensor that can sense the swing angle of the second swinging member 421. At this time, the second sensor 422 can sense that the second swinging member 421 is subjected to a greater force or a greater swing angle and send a corresponding signal to cause the controller 30 to control the conveyor belt 22 to stop running, thereby preventing the bicycle 50 from rushing backwards out of the bicycle training platform 10 and causing danger. It can be seen that the second sensing device 42 in this embodiment has the function of sensing both the normal deceleration and the abnormal speed reduction of the bicycle, which can not only efficiently sense the abnormality, but also make the structure of the bicycle training platform 10 simple.

[0037] See also Figure 1 and Figure 8 As shown, the electric treadmill 20 in this embodiment is provided with two stoppers 26 on the left and right sides of the base 21, and a rear side 411c of each upright 411a of the first swinging member 411 is adjacent to a stopper 26, so that the first swinging member 411 will only swing forward when pushed forward by the wheel 51, and will not swing from the Figure 4 The first swing member 411 may be further provided with a spring (not shown) so that the first swing member 411, which is no longer pushed by the wheel 51, returns to the position shown in FIG. Figure 4 A front side 421c of each upright rod 421a of the second swing member 421 is adjacent to a stopper 26, so that the second swing member 421 will only swing backwards due to the push of the wheel 51, and will not swing backwards. Figure 4 The second swing member 421 may be further provided with a spring (not shown) so that the second swing member 421, which is no longer pushed by the wheel 51, returns to the position shown in FIG. Figure 4 Position shown.

[0038] In summary, the bicycle training platform 10 of the present invention does not need to be provided with handrails for users to hold on both sides of the electric treadmill 20, but allows the user to achieve balance at the beginning of riding through the auxiliary plate 12. The auxiliary plate 12 only needs to be slightly higher than the conveyor belt 22, so its height position is very low and will not cause obstruction, inconvenience and pressure to the user. In addition, a pedal switch 14 can be further provided on the auxiliary plate 12 to quickly, conveniently and safely start and shut down the electric treadmill 20. Furthermore, the controller 30 is adjusted to the running speed of the conveyor belt 22 to match the current riding speed of the user through the sensing unit 40, which can not only prevent the bicycle 50 from rushing out of the bicycle training platform 10 and causing danger, but also allow the user to adjust the riding speed by himself during the training process, thereby achieving a good riding training effect.

[0039] Finally, it must be stated again that the constituent elements disclosed in the aforementioned embodiments of the present invention are only for illustration and are not intended to limit the scope of patent protection of this case. Replacements or changes of other equivalent elements should also be covered by the scope of patent protection of this case. For example, the vertical side panels 12b on the left and right sides of the auxiliary plate 12 can extend downward and be directly supported on the ground, as long as the top of the auxiliary plate 12 for the user to step on can be placed across the conveyor belt 22. Secondly, the shape of the auxiliary plate 12 is not limited to the form disclosed in the aforementioned embodiments, that is, it is not limited to having two vertical side panels 12b and a horizontal panel connecting the two vertical side panels 12b, as long as it has a stepping portion suspended above the conveyor belt 22 and for the user to step on. In addition, any contact or non-contact switch that can start and shut down the electric treadmill 20 can replace the stepping switch 14. In other words, the stepping switch 14 can be omitted. In this way, Figure 1 and Figure 3 The pedal switch 14 shown may be merely an inclined pedal extending upward and forward from the top surface of the auxiliary plate 12 for the user to step on and rest.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the creative spirit and protection scope of the technical solutions of the various embodiments of the utility model.
