[0002] The types of existing exercise bikes are becoming increasingly diverse to meet different social needs. While traditional bicycles can be used for exercise, they cannot provide a systematic approach or professional guidance for competition and training, so improvements are inevitable.

[0003] Currently, many new devices have emerged. For example, Chinese patent application number 201210275897.X discloses a smart racing / exercise bike that can swing and pitch, including a frame and a base that can be stably placed on the ground or a flat surface. The frame includes a frame, drive wheels, pedals, damping wheels, handlebars, and a seat. A swing mechanism is also installed between the frame and the base. The swing mechanism includes a swing bracket and a swing support assembly. The swing bracket is connected to the base through the swing support assembly, allowing the frame of the bike to swing left and right relative to the base. The racing / exercise bike also includes a pitch mechanism, which is installed between the frame of the bike and the swing bracket of the swing mechanism, allowing the frame of the bike to pitch forward and backward relative to the swing bracket.

[0004] While the aforementioned existing patented technologies involve competition and fitness, they are not optimized enough for more realistic scenarios and fairer competition, and the simulation level is not high. Summary of the Invention

[0009] A stationary bike suitable for competition includes a support frame and a frame mounted on the support frame. The frame includes a swaying frame mounted on the support frame, a drive wheel, pedals, damping wheels, a handlebar, and a seat mounted on the frame. The support frame is mounted on a rotating mechanism that can rotate horizontally and can also tilt forward and backward.

A damping plate is fixed on the lower side of the vehicle beam body, located above and in front of the front lower inclined rotating shaft. A damping spring is connected between the damping plate and the left and right halves of the damping support rod, respectively. The damping spring is axially perpendicular to the front lower inclined rotating shaft.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0027] Example 1, as Figure 2 , 3As shown, a competitive exercise bike includes a support frame 1 and a frame mounted on the support frame 1. The frame includes a frame 21 mounted on the support frame 1 and capable of lateral swaying, a drive wheel 22 mounted on the frame 21, pedals 23, damping wheels 24, a handlebar 25, and a seat 26. These are all based on the conventional structure of an exercise bike. The difference is that in this embodiment, the support frame 1 is mounted on a rotating mechanism that can rotate horizontally, which is used to simulate turning. This requires the rider to control their centripetal force to pedal. In addition, the support frame 1 needs to be designed to also tilt forward and backward, with the forward and backward direction being the direction of pedaling. The simulation provides dynamic movement in all directions, creating a more three-dimensional and realistic experience. It can simulate a wider variety of scenarios. Furthermore, a gyroscope is embedded in the front of the bike (25), providing accurate signals of orientation, level, position, speed, and acceleration. This serves two purposes: firstly, to obtain various parameters during riding to assist athletes or trainees in developing more personalized training plans; secondly, to provide reference data during competitive events; and thirdly, for safety reasons, to promptly alarm and suspend subsequent automatic control mechanisms and damping wheels in case of abnormal data, ensuring user safety. Furthermore, a built-in processor (3) is installed on the frame (21) to receive gyroscope signals. This processor can be a readily available microprocessor and can be configured with an LCD display screen, all located in the front of the bike. The built-in processor (3) is used to collect and analyze data from the sensors. This type of exercise bike provides users with a more realistic and diverse riding experience, allows for more reasonable fitness plans, and is more suitable for competitive riding.

[0028] Preferably, the frame 21 includes a central main column 211, a rear wheel mounting frame 212 fixed to the rear of the central main column 211, and a frame 213 fixed to the front of the central main column 211. These are conventional structures. The rear wheel mounting frame 212, the central main column 211, and the frame 213 can all be made of metal materials, such as steel. Of course, lightweight and high-strength materials such as carbon fiber can also be used. In its initial state, that is, in its unused state, the central main column 211 is kept as upright as possible, that is, basically perpendicular to the ground. Preferably, it is slightly tilted backward by about 10 degrees. This is a more ergonomic structural design for bicycle frames. Furthermore, the front end 25 is fixed to the front of the frame 213. The front end 25 adopts a common front end structure and needs to have a handlebar. A drive wheel 22 is rotatably connected to the central main column 211, and a corresponding wheel axle is installed on the central main column 211, on which the drive wheel 22 is mounted. The damping wheel 24 is rotatably connected to the rear wheel mounting frame 212. Of course, a corresponding wheel axle also needs to be mounted on the rear wheel mounting frame 212, and the damping wheel 24 is mounted on that wheel axle. To allow the drive wheel 22 to transmit power to the damping wheel 24, both the axle containing the drive wheel 22 and the axle containing the damping wheel 24 can have sprockets and be equipped with a chain that surrounds both sprockets to achieve transmission. Alternatively, other existing structures such as a drive belt can also be implemented, which will not be elaborated upon here.

[0029] To better conform to the human body's habit of swaying left and right, a rear upper inclined rotating shaft 41 that allows the frame 21 to sway left and right is fixed on the central main column 211 or the rear wheel mounting frame 212. A front lower inclined rotating shaft 42 that works with the rear upper inclined rotating shaft 41 to allow the frame 21 to sway left and right is fixed on the lower side of the beam 213. The center lines of the rear upper inclined rotating shaft 41 and the front lower inclined rotating shaft 42 are on the same straight line, so that the entire frame sways left and right around a rotating shaft that tilts forward and downward. Of course, this rotating shaft is discrete, that is, the rear upper inclined rotating shaft 41 and the front lower inclined rotating shaft 42 together in the same extending direction form and support the frame.

[0030] Furthermore, the support frame 1 is provided with a rear upper inclined sleeve 51 for the rear upper inclined rotating shaft 41 to rotate and a front lower inclined sleeve 52 for the front lower inclined rotating shaft 42 to rotate. Of course, in order to make the swing smoother and more natural, several bearings should be embedded in the rear upper inclined sleeve 51 and the front lower inclined sleeve 52, and the rear upper inclined rotating shaft 41 and the front lower inclined rotating shaft 42 can be fitted and installed in the inner ring of these bearings. In addition, it is preferable that the angle between the rear upper inclined rotating shaft 41 and the middle main column 211 is 30-60 degrees. For example, if the angle between the rear upper inclined rotating shaft 41 and the middle main column 211 is selected as 40 degrees, then the angle between the front lower inclined rotating shaft 42 and the middle main column 211 is also 40 degrees. The angle between the rear upper inclined rotating shaft 41 and the horizontal ground in the initial state is between 40-50 degrees, which depends on the inclination of the middle main column 211.

[0031] In this structure, there is no need for a front wheel; only a central drive wheel and a rear damping wheel are needed. This results in better overall balance, and more electronic control units and shelves can be installed on the front.

[0032] Regarding the design of the support frame 1, the base of the support frame 1 can be a square frame structure initially laid flat. Based on this, the front side of the support frame 1 has a front bottom reinforcing rod 11. The front bottom reinforcing rod can be fixedly connected to the front part of the base frame of the support frame 1 and extends backward, maintaining a straight state. The front lower inclined sleeve 52 is fixed to the rear end of the front bottom reinforcing rod 11. Of course, the front lower inclined sleeve 52 is inclined, as previously explained. An arc-shaped rear reinforcing arc rod 510 is fixed to the front part of the base frame of the support frame 1. The rear reinforcing arc rod 510 is arched upward and backward, and the rear upper inclined sleeve 51 is fixed to the upper end of the rear reinforcing arc rod 510. The rear reinforcing arc rod 510 perfectly surrounds the outer periphery of the upper rear part of the damping wheel, providing both aesthetics and protection.

[0033] Preferably, the front bottom reinforcing rod 11 is fixed with left and right extending damping support rods 12. Each damping support rod 12 has half on each side of the front bottom reinforcing rod 11, forming a cross shape. A damping plate 13 is fixed to the lower side of the vehicle beam 213, positioned above and in front of the front downward-sloping rotation shaft 42. A damping spring 14 is connected between the damping plate 13 and the left and right halves of the damping support rod 12, respectively. The damping spring 14 is axially perpendicular to the front downward-sloping rotation shaft 42. This provides highly reliable damping and support for left and right swaying.

[0034] Preferably, to improve the reliability of left and right swaying, the following design is adopted: a left and right sway guide rail 251 for guiding the left and right swaying of the frame 21 is fixed on the front side of the vehicle head 25; a left and right sway guide post 252 for guiding the left and right swaying of the left and right sway guide rail 251 is fixed on the front side of the support frame 1; a guide roller 253 inserted into the left and right sway guide rail 251 is fitted at the top of the left and right sway guide post 252; the left and right sway guide rail 251 forms an arc-shaped guide rail groove, and the guide roller 253 is embedded in the guide rail groove; the guide roller 253 can be a universal ball or a ball bearing, etc. The left and right sway guide post 252 also needs to be perpendicular to the front downward inclined rotation axis 42 to ensure the stability of left and right swaying.

[0035] For control purposes, the exercise bike also includes an external processor 5. The built-in processor 3 is electrically connected to a transceiver device, which communicates with the external processor 5. The external processor 5 can be a large processor for more complex algorithms and controls. The transceiver device is mainly used for transmitting data and other information, allowing the built-in processor 3 to upload data, or data that has been simply processed and analyzed, to the external processor 5. Based on this data, the external processor can determine the user's usage, such as riding distance, calories burned, degree of lateral sway, degree of pitch, and degree of cornering, to assist the user in subsequent guided training. It can also be used as a standard for competition. Preferably, a riding distance sensor 240 is installed on the rear wheel mounting frame 212 to detect the rotation distance of the damping wheel 24. The output of the riding distance sensor 240 is electrically connected to the built-in processor 3. The riding distance sensor 240 can use an existing angular velocity sensor converted into rotation distance, or directly use some displacement sensors that measure rotation distance. This allows for the measurement of riding distance and facilitates the determination of competition results, such as comparing who rides a longer distance in the same amount of time.

[0036] Furthermore, the rotating mechanism includes a frame 61, a rotating platform 62 mounted on the frame 61, and a rotary motor 63 for rotating the rotating platform 62. The motor shaft 630 of the rotary motor 63 is fixedly connected to the rotating platform 62, and the motor shaft 630 is located at the center of the rotating platform 62 and extends downward. The support frame 1 is fixed to the upper surface of the rotating platform 62. The motor shaft 630 passes through the inner ring of a slewing bearing 64, and the outer ring of the slewing bearing 64 is fixed to the frame 61. That is, the rotating platform 62 is mounted on the frame 61 via the slewing bearing 64 and can rotate. This rotating design can effectively simulate cornering, which is a very important consideration in cycling. Cornering is an unavoidable situation in any racing, and this design can greatly improve the effectiveness of fitness and competition.

[0037] In addition, the pitching motion of the support frame 1 can be achieved using existing structures, or it can be achieved using new structures in subsequent embodiments, which can have better performance.

[0038] The design of the above structure optimizes the diversity of exercise bikes, enhances their simulation level, and makes them more suitable for training recovery and competition.

[0039] Considering practical use and construction issues, the structure below the rotating platform 62 can be pre-embedded underground. This means pre-embedded pits can be dug on the ground surface to house the rotating mechanism and other structures below the main body of the vehicle, thus avoiding occupying usable space. This applies to the exercise bike system mentioned in Example 2, where the lower parts can also be pre-embedded underground for ease of use and a more aesthetically pleasing appearance.

[0040] Example 2, as Figure 4 As shown, this embodiment is a system implemented based on Embodiment 1, namely a competitive exercise bike system. Specifically, it includes two or more exercise bikes as described in Embodiment 1, generally arranged with a back-to-back interval; two bikes are used as an example here. This system is very suitable for competition. The system also includes a moving guide rail d for the horizontal movement of the exercise bike. The moving guide rail d generally consists of two rails arranged side-by-side. Four sliders can be mounted on the frame 61, with two sliders on each side, corresponding to the two moving guide rails. Of course, the sliders need to have locking devices; they need to be unlocked during movement. When the frame 61 moves to the designated position, it needs to be locked onto the moving guide rail d by the locking devices.

[0041] Furthermore, a first gear c1 is fixed on the motor shaft 630, initially in a flat, fixed position on the motor shaft 630. An intermediate synchronous drive gear c2, capable of horizontal movement on the moving guide rail d, is provided between adjacent exercise bikes. The two adjacent first gears c1 and the intermediate synchronous drive gear c2 between them can mesh. The intermediate synchronous drive gear c2 can be mounted on a gear mounting frame, which can also be equipped with a slider with a locking device, allowing the gear mounting frame to move and lock on the moving guide rail d. Thus, both the front and rear exercise bikes and the intermediate synchronous drive gear c2 between them can move back and forth on the moving guide rail d, allowing the first gear c1 on the two adjacent exercise bikes and the intermediate synchronous drive gear c2 to either separate or mesh. For example, during a competition, the bikes need to be engaged to achieve synchronized rotation. This means the turntable 62 can rotate synchronously, ensuring highly synchronized cornering. If synchronization were achieved using different motors, differences in rider load and other factors would prevent achieving perfect synchronization. In competitive mode, one method involves riding the longest distance under the same conditions. Therefore, the scenarios must be synchronized, including turning, pitching (representing gradient), and lateral swaying. This swaying is controlled by the rider's skill and reflects their riding ability, determined by distance traveled. Under the same conditions of time, turns, inclines, and damping force, the rider whose damping wheel rolls more, resulting in a longer distance, wins. Therefore, the forward and backward pitch of the exercise bike must also be synchronized as much as possible.Therefore, this application provides a new structure that allows the movable guide rail d to pitch forward and backward. The front ends and rear ends of the two movable guide rails d can be connected and fixed together by a front fixing rod g1 and a rear fixing rod g2, respectively. One of the front fixing rod g1 and the rear fixing rod g2 can be raised and lowered, thus enabling pitching forward and backward. For example, two upright fixing posts h are provided on the lower part of the movable guide rail d. The front fixing rod g1 is cylindrical and passes laterally through these two fixing posts h, and the front fixing rod g1 can rotate on the fixing posts h. A component with an axial direction in the left-right direction can be mounted on the fixing posts h. The bearing has an inner ring through which the front fixed rod g1 passes and is supported. At the rear, below the moving guide rail d, is a rearward-positioned lifting device s. The lower part of the lifting device is rotatably connected to the fixed support pile z, and the upper part is rotatably connected to the rear fixed rod g2. For example, if the lifting device s is a lifting cylinder or hydraulic cylinder, the piston rod head is passed through and fitted onto the rear fixed rod g2 for rotatable connection. The rear fixed rod g2 is also cylindrical. The bottom of the cylinder body is rotatably connected to the fixed support pile z. For example, if the fixed support pile z uses a hinge seat with a hinge shaft, the bottom of the cylinder body allows this hinge shaft to pass through. The lifting device can also be automatically controlled by a processor, allowing for the design of uphill and downhill sections according to different scenarios. The tilting of the stationary bike is achieved by the up-and-down tilting of the moving guide rail d.

[0042] In this system, when different bikes compete, turns and inclines at the same time can be synchronized very well, making the competition fairer. Of course, in this competition mode, only the motor of one bike needs to be controlled by the processor. Furthermore, once the first gear c1 of two or more exercise bikes and the adjacent intermediate synchronization drive gear c2 disengage after the moving guide rail d moves, these exercise bikes can operate independently and can be used for training and rehabilitation.

[0043] Example 3, as Figure 1As shown, a method for racing on a stationary bike includes the following steps: (a) Storing several riding scenarios in the stationary bike. These riding scenarios can be real-life stadium race tracks, mountain roads or road race sections of bicycle open races, etc. The stationary bike is equipped with a corresponding memory, which can store this information for retrieval and use. For example, some plain sections, some rugged and winding sections, or some real-life race sections. These sections can be stored in the processor in advance. The stationary bike used is the stationary bike described in the aforementioned embodiments 1 and 2. (b) Selecting and recognizing one of the riding scenarios. After selection, a scenario matching the selected scenario should be presented. The processor controls the rotation mechanism, lifting device, etc., through instructions to simulate turning and pitching. Here, the simulation is based on the riding scenario in step (a), that is, step (c) the stationary bike simulates according to the recognized scenario. The simulation information includes curve information and uphill and downhill information. Curve information only includes the curvature and length data of the curve, which is simulated by the rotation mechanism. Uphill and downhill information is the pitch angle, which is simulated by the lifting device. The user rides the stationary bike in real-time, following the simulated terrain and changing their riding posture accordingly. Once the ride is complete (step (d) – the stationary bike ride is finished and the damping wheel rotation distance in that scenario is obtained) – step (e) – uploads and evaluates this rotation distance, which represents the total riding distance. For competition participants, the rotation distance of each user's ride provides a basis for evaluation. Uploading this rotation distance, i.e., the detected data, allows the processor to analyze and determine the winner. The rotation distance of each participant's damping wheel can be detected by sensors. This method allows participants to ride individual stationary bikes, compete in the same scenario at the same time, and ultimately determine the winner based on the riding distance, i.e., the rotation distance of the damping wheel. However, the above method is best suited for the exercise bike system in Example 2. The exercise bikes in this system can perform cycling races in the same scenario very well, making it more fair and just, and very suitable for multi-person competition. Of course, the cycling scenarios can be repeated, and as mentioned above, the same time can also be specified, and it is not necessary to complete the entire ride. Overall, it is also highly flexible.

[0044] Furthermore, before step (d), it is necessary to determine the damping level of the damping wheel. If the damping wheel adopts an electromagnetic damping structure, the damping level of the damping wheel can also be controlled by a controller. The participants can be grouped according to their abilities and divided into different groups for the competition.

[0045] In addition, the above system is also very beneficial for user training. The processor can introduce neural network models to train new auxiliary training scenarios. For example, after step (e), the speed when cornering, the uphill speed and the downhill speed are calculated. At least based on the aforementioned three speeds, as well as the riding distance and riding time, new auxiliary training scenarios are generated. If combined with the following information, such as the user's usual selected scenarios, riding distance, time and other data, and the bicycle can also be equipped with some force sensors to test the magnitude of damping force, the magnitude of tilt pressure and other data, more effective auxiliary training scenario modes needed by similar groups of people can be generated for more targeted auxiliary training.

[0046] Furthermore, to optimize training, auxiliary telescopic rods f can be installed on both sides of the vehicle body. The auxiliary telescopic rods f can be connected to the shock-absorbing support rod 12 by a pneumatic rod, and the extension direction is consistent with that of the shock-absorbing spring. The piston rod head of the auxiliary telescopic rod f can be fitted with a rubber ring or other shock-absorbing material. When assisted swinging is needed, the auxiliary telescopic rod f can extend to resist the shock-absorbing plate, and of course, it can also further push the shock-absorbing plate. In this way, when the human body's twisting ability is insufficient during left and right swinging, the auxiliary telescopic rods f can be used to assist in left and right swinging training in some special situations during riding.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
