Intelligent spinning cycle and implementation method thereof

Abstract

The application discloses an intelligent dynamic bicycle and an implementation method thereof. The dynamic bicycle is characterized in that four moving mechanisms are arranged at the two ends of the bottom of the bicycle support, and a dynamic mechanism is arranged at each moving mechanism. The four dynamic mechanisms are combined to form a simulation dynamic device. The dynamic mechanism is vertically arranged on the bicycle support. The dynamic mechanism comprises a ball head, an extension rod, a self-locking extension device and a bottom circular table which are sequentially connected. The extension rod is connected with the bicycle support through the ball head. The self-locking extension device is connected with the ground through the bottom circular table or not. The input of the self-locking extension device is connected with the output of the control unit of the touch screen. In the dynamic mode, the dynamic mechanism is controlled and the moving mechanism is controlled. The method comprises the following modes: a slope sub-mode, a stone sub-mode and a moving cross-country sub-mode. The bicycle damping is automatically adjusted. When the bicycle simulates uphill, the damping is increased. The greater the slope is, the greater the damping is. When the bicycle simulates downhill, the damping is reduced. The greater the slope is, the smaller the damping is.

Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, specifically to a stationary bike. Background Technology

[0002] In recent years, society's material living standards have entered a phase of rapid development, and people have gradually shifted their pursuits from material to spiritual aspects. Against this backdrop, people are paying more attention to inner balance and satisfaction, and their focus on physical and mental health is increasing. As a type of fitness equipment, the indoor bicycle is effective as an aerobic exercise machine, improving cardiovascular function and strengthening muscles to sculpt body lines. Indoor bicycles not only meet people's need for physical exercise but also provide a pleasant exercise experience, helping people release stress and soothe emotions.

[0003] In the field of indoor cycling technology, the main problem is the insufficient dynamic experience during exercise. Traditional indoor cycling bikes can only perform simple riding exercises, lacking sufficient dynamic effects and failing to meet user needs. In addition, existing indoor cycling bike structural designs also have some flaws, such as inconvenience in movement, which affects the user experience.

[0004] For example, a stationary bike with patent publication number CN220294065U lacks a motion simulation device, thus failing to meet users' needs for a dynamic riding experience. Another stationary bike with patent publication number CN116407807A, while incorporating a device to simulate different road conditions to enhance the user's riding experience, suffers from an overly complex and cumbersome overall structure and a lack of safety protection measures, posing potential safety hazards in actual use. Summary of the Invention

[0005] This invention addresses the problems existing in exercise bikes by proposing an intelligent exercise bike and its implementation method. The intelligent exercise bike achieves: forward and backward swaying and left and right swaying for richer exercise effects and increased enjoyment; automatic damping adjustment based on incline; and automatic deployment of safety protection measures during simulated dynamic movements. This improves the overall performance and user experience of the exercise bike.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] A smart exercise bike includes a touchscreen 12 mounted on the front for function selection, control, and display; a damping adjustment device that uses the control unit of the touchscreen 12 to control the electric telescopic rod 303 to adjust the distance between the magnet 304 and the rear flywheel 301, thereby adjusting the flywheel damping; the lower end face of the bike body 1 is horizontally fixed to the upper end face of an arc-shaped curved frame 105 made of steel pipe; two bike supports 101 are fixed at the midpoint and are horizontally and vertically perpendicular to the arc-shaped curved frame 105, respectively mounted at the left and right ends of the arc-shaped curved frame 105; and four moving mechanisms are vertically perpendicular to the bike supports 101 and respectively mounted at the bottom ends of the left and right bike supports 101, forming a moving device; the moving mechanism includes a drive wheel 5 with a drive motor 502 mounted on it, and a built-in steering servo 503; the drive wheel 5 is connected to the frame assembly and... The output shaft of the steering servo 503 is connected, and the steering servo 503 is fixedly connected to the bottom of the bicycle bracket 101 through its outer casing. The input of the steering servo 503 and the input of the drive motor 502 are respectively connected to the output of the control unit of the touch screen 12. Motion mechanisms are also installed at both ends of the bottom of the left and right bicycle brackets 101. The four motion mechanisms constitute a simulated motion device. The motion mechanisms are vertically installed on the bicycle brackets 101. The motion mechanism includes a ball head 801, a telescopic rod 802, a self-locking telescopic device 8, and a bottom truncated cone 803 connected in sequence. The telescopic rod 802 is connected to the bicycle bracket 101 through the ball head 801. The self-locking telescopic device 8 is either on the ground or not on the ground through the bottom truncated cone 803. The input of the self-locking telescopic device 8 is connected to the output of the control unit of the touch screen 12.

[0008] The damping adjustment device described above also includes a gyroscope sensor installed inside the curved frame 105 for real-time monitoring of vehicle body posture changes. The output of the gyroscope sensor is connected to the control unit input of the touch screen 12.

[0009] The above-mentioned vehicle body 1 has two independent safety protection devices on its lower sides. The safety protection devices include a safety air cushion 7, an air pump 6, a pipe 601, and a rotatable bracket 701. One end of the pipe 601 is connected to the air pump 6, and the other end is connected to the safety air cushion 7. The safety air cushion 7 is connected to the extension frame 103, which is fixedly connected to the lower middle section of the arc-shaped frame 105 by the rotatable bracket 701, and is connected by a hinge-type fixing connector 104. The air pump 6 is used to inflate and deflate the safety air cushion 7. The control signal input for inflating and deflating the air pump 6 is respectively connected to the control unit output of the touch screen 12. In the outer safety protection device, the air pump 6 is fixedly installed on the outer side of the right bicycle bracket 101, and in the inner safety protection device, the air pump 6 is fixedly installed on the inner side of the right bicycle bracket 101.

[0010] The air pump 6 described above is also equipped with a control switch that is directly connected to the battery 4 to control the inflation.

[0011] To achieve the above objectives, another technical solution of the present invention is:

[0012] A method for implementing an intelligent exercise bike, wherein the exercise mode includes the following steps:

[0013] (1) When the ramp sub-mode is selected:

[0014] ① The two self-locking telescopic devices 8 on the front bicycle support 101 are synchronously controlled to extend the telescopic rod 802 to the same length H, thereby raising the front bicycle support 101.

[0015] ② After the two self-locking telescopic devices 8 on the front bicycle support 101 extend the telescopic rod 802 to the same length H, the two self-locking telescopic devices 8 on the rear bicycle support 101 are simultaneously controlled to extend the telescopic rod 802 to the same length H, thus raising the rear bicycle support 101.

[0016] ③ After the two self-locking telescopic devices (8) on the rear bicycle support 101 extend the telescopic rod (802) to the same length H, the two self-locking telescopic devices (8) on the front bicycle support 101 are simultaneously controlled to retract the telescopic rod 802 to the extended length H, restoring the height of the front bicycle support 101 relative to the ground.

[0017] ④ After the front bicycle support 101 returns to its ground height, the two self-locking telescopic devices 8 on the rear bicycle support 101 are simultaneously controlled to retract the telescopic rod 802 to the extended length H, restoring the rear bicycle support 101 to its ground height.

[0018] ⑤ After the rear bicycle bracket 101 returns to the ground height, return to step ① of (1) and perform cyclic control.

[0019] (2) When the pebble mode is selected:

[0020] According to the set frequency, control the four self-locking telescopic devices 8 respectively, so that the corresponding telescopic rods 802 extend / retract by the same length, and control the four telescopic rods 802 to extend by different lengths, so that the vehicle body 1 rises and falls with the multi-angle tilt of the single vehicle support 101.

[0021] (3) When the mobile off-road sub-mode is selected:

[0022] The two self-locking telescopic devices 8 at the front end retract simultaneously, causing the two drive wheels 5 at the front end to touch the ground. The two self-locking telescopic devices 8 at the rear end are controlled to extend simultaneously or alternately rise and fall to form left and right tilting. The drive motor 502 and steering motor 503 at the front end are controlled to cooperate to turn to the left and move a set distance, and then turn back to the right and move back, so that the front end can move in a fan shape within the movable range.

[0023] The length H mentioned above is a set length.

[0024] To achieve the above objectives, another technical solution of the present invention is:

[0025] A method for implementing an intelligent exercise bike, wherein the damping adjustment method in exercise mode includes the following steps:

[0026] The gyroscope sensor captures the forward and backward tilt of the vehicle body 1 in real time and sends the data to the control unit of the touchscreen 12 for processing.

[0027] When the front side is detected to be higher than the rear side, the uphill riding environment is simulated, and the extension length of the electric telescopic rod 303 is controlled. The greater the slope of the uphill, the smaller the distance between the magnet 304 and the flywheel 301. Thus, under the action of the magnetic field, the greater the slope of the uphill, the greater the resistance for the user to ride.

[0028] When the front side is detected to be lower than the rear side, a downhill riding environment is simulated, and the retraction distance of the electric telescopic rod 303 is controlled. The greater the slope of the downhill, the greater the distance between the magnet 304 and the flywheel 301. Thus, under the action of the magnetic field, the slope of the downhill is greater, and the resistance of the user riding is smaller.

[0029] To achieve the above objectives, another technical solution of the present invention is:

[0030] A method for implementing an intelligent exercise bike, comprising the following steps for controlling the inflation and deflation of the safety airbag 7:

[0031] When the sensor mode is activated, the air pump 6 runs through the pipe 601 to quickly inflate the safety air cushion 7 until the safety air cushion 7 expands and deploys.

[0032] When the motion mode is turned off, the air pump 6 runs through the pipe 601 to vent the safety air cushion 7 until it retracts back to its original position.

[0033] Before getting on the bike, if you press the control switch that is directly connected to the battery 4 to control the inflation, the air pump 6 will run to control the safety air cushion 7 to inflate and unfold, so that users who are not tall can step on the inflated safety air cushion 7 as a step to sit on the seat 2 of the exercise bike. After sitting down, start the exercise bike and control the air pump 6 to inflate and deflate the safety air cushion 7 through the touch screen 12. Beneficial effects

[0034] A smart exercise bike and its implementation method, comprising:

[0035] ① When simulating motion, by controlling the forward and backward, left and right swaying and movement, it can simulate slopes, rocky paths, and even cross-country running, achieving richer motion effects and increasing the fun of exercise;

[0036] ② When simulating motion, the damping is automatically adjusted according to the slope of the bicycle. The greater the slope of the uphill section, the greater the damping, and the greater the slope of the downhill section, the less the damping.

[0037] ③ When simulating dynamic motion, the safety airbag will automatically deploy to protect the rider;

[0038] ④ The safety air cushion can be manually deployed, allowing shorter users to step onto the inflated air cushion as a step to sit on the seat of the exercise bike. Attached Figure Description

[0052] Traditional indoor bikes lack simulated dynamic effects and safety features, so there is a need for an indoor bike that provides a more user-friendly experience.

[0053] Reference Appendix Figures 1 to 10As shown, the present invention provides an intelligent dynamic bicycle, including a touch screen 12 mounted on the front of the bicycle for function selection, control, and display; a damping adjustment device that uses the control unit of the touch screen 12 to control the electric telescopic rod 303 to adjust the distance between the magnet 304 and the rear flywheel 301 of the bicycle to adjust the flywheel damping; the lower end face of the bicycle body 1 is horizontally fixed to the upper end face of the arc-shaped curved frame 105 made of steel pipe; two bicycle supports 101 are fixed at the midpoint and are horizontally and vertically perpendicular to the arc-shaped curved frame 105 and respectively mounted at the left and right ends of the arc-shaped curved frame 105; and four moving mechanisms are vertically perpendicular to the bicycle supports 101 and respectively mounted at the bottom ends of the left and right bicycle supports 101 to form a moving device; the moving mechanism includes a drive wheel 5 with a drive motor 502 mounted on it, and a built-in steering servo 503; the drive wheel 5 is supported by a support... The frame assembly is connected to the output shaft of the steering servo 503. The steering servo 503 is fixedly connected to the bottom of the bicycle frame 101 through its outer casing. The input of the steering servo 503 and the input of the drive motor 502 are connected to the output of the control unit of the touch screen 12. Motion mechanisms are also installed at both ends of the bottom of the left and right bicycle frames 101. The four motion mechanisms constitute a simulated motion device. The motion mechanisms are vertically installed on the bicycle frame 101. The motion mechanism includes a ball head 801, a telescopic rod 802, a self-locking telescopic device 8, and a bottom truncated cone 803 connected in sequence. The telescopic rod 802 is connected to the bicycle frame 101 through the ball head 801. The self-locking telescopic device 8 is either on the ground or not on the ground through the bottom truncated cone 803. The input of the self-locking telescopic device 8 is connected to the output of the control unit of the touch screen 12.

[0054] The damping adjustment device described above also includes a gyroscope sensor installed inside the curved frame 105 for real-time monitoring of vehicle body posture changes. The output of the gyroscope sensor is connected to the control unit input of the touch screen 12.

[0055] The above-mentioned vehicle body 1 has two independent safety protection devices on its lower sides. The safety protection devices include a safety air cushion 7, an air pump 6, a pipe 601, and a rotatable bracket 701. One end of the pipe 601 is connected to the air pump 6, and the other end is connected to the safety air cushion 7. The safety air cushion 7 is connected to the extension frame 103, which is fixedly connected to the lower middle section of the arc-shaped frame 105 by the rotatable bracket 701, and is connected by a hinge-type fixing connector 104.

In the outer safety protection device, the air pump 6 is fixedly installed on the outer side of the right bicycle bracket 101, and in the inner safety protection device, the air pump 6 is fixedly installed on the inner side of the right bicycle bracket 101.

[0056] The air pump 6 described above is also equipped with a control switch that is directly connected to the battery 4 to control the inflation.

[0057] For details, please refer to the appendix. Figure 3 The kinetic energy recovery device includes a belt 302 that drives the flywheel 301 and the generator 3, and a battery 4 connected to the output of the generator 3. This allows the flywheel 301 to rotate during riding, driving the generator 3 via the belt 302. A portion of the generated electricity supplies the bicycle's power needs, while the excess is stored in the battery 4. By converting the kinetic energy generated during riding into electrical energy, the device achieves energy reuse and energy conservation and emission reduction.

[0058] For details, please refer to the appendix. Figure 4 The front of the bicycle is embedded in the frame 1 via the head of the lifting rod 1102, and is slidably connected to the frame 1. It has internal slots and slots, allowing users to manually adjust its height as needed. The front of the bicycle, which has two symmetrically placed sensor grips 11, also has a touch screen bracket 1101 that is slidably connected to the front of the bicycle and has a telescopic structure. This bracket is used to mount the touch screen 12, allowing users to adjust the distance between the touch screen bracket and the front of the bicycle within a certain range as needed. By changing the length of the rod, users can freely adjust the position of the touch screen on the front of the bicycle to adapt to different usage scenarios and personal needs. The grips 11 are equipped with multiple sensors, including a heart rate sensor, speed sensor, resistance sensor, and blood pressure sensor. These sensors monitor the user's heart rate, calories burned during riding, blood pressure changes, body fat, body water, and other health information in an AND / OR manner. This data can be displayed to the user through the touch screen 12. In addition, the touch screen 12 can also provide various entertainment activities and fitness training functions.

[0059] For details, please refer to the appendix. Figure 5 , 6 As shown, the seating mechanism includes: a seat 2 with massage balls 203 inside, a seat base 201, and a seat lifting rod 202; the massage balls 203 are fixedly installed inside the seat, and when the user needs a massage, the massage balls 203 can be rotated through the terminal touch screen to realize the massage function; the seat cushion on the surface of the seat 2 can be covered with heating resistance wires and temperature sensors, and the heating function can be controlled by the touch screen terminal. When a certain temperature is reached, the heating will automatically disconnect, and the user can also manually stop the heating; the seat base 201 is designed with a groove structure, and the seat 2 is connected to the seat base 201 through the groove, and there are locking slots inside to ensure its stability. The user can adjust the front and back distance of the seat according to their needs; the seat base 201 is rigidly connected to the seat lifting rod 202, and the seat lifting rod 202 is embedded in the vehicle body. The lifting rod and the vehicle body are slidably connected, and there are locking slots inside. The user can adjust the extension length of the seat lifting rod 202 according to their own needs to realize the adjustment of the seat height.

[0060] For details, please refer to the appendix. Figure 1 Appendix Figure 7The mobile device consists of four moving mechanisms installed at the bottom ends of the front (left) and rear (right) bicycle brackets 101 respectively. Each moving mechanism includes a drive wheel 5 with a drive motor 502 and a built-in steering servo 503. The rod of the drive wheel 5 is rigidly connected to the bicycle bracket 101, and the built-in steering servo 503 is used for multi-angle steering adjustment of the drive wheel 5.

[0061] When the exercise bike does not need to be moved, the self-locking telescopic device 8 maintains the initial extension distance and self-locks the telescopic rod 802. At the initial extension distance, the distance between the bottom truncated cone 803 of the self-locking telescopic device 8 and the bottom surface of the bike frame 101 is greater than the distance between the bottom surfaces of the four drive wheels 5 and the bottom surface of the bike frame 101. The bottom truncated cone of the self-locking telescopic device 8 is grounded and supported, while the drive wheels 5 are suspended in the air, thus fixing the exercise bike in this position.

[0062] When a user needs to move the exercise bike, they can control the exercise bike to move to the designated location by clicking the move mode on the touch screen 12.

[0063] When a user selects the "Mobile Off-Road" sub-mode within the Dynamic mode, the exercise bike will tilt and sway at multiple angles on the bike frame 101. Simultaneously, the movement device will control the exercise bike to move within a specified range according to a set pattern, thereby enhancing the user's dynamic experience through swaying and movement.

[0064] The specific implementation of the movement control of the exercise bike is as follows: control the self-locking telescopic device 8 to retract to the minimum distance. At this time, the distance between the bottom truncated cone of the self-locking telescopic device 8 and the bottom surface of the bicycle frame 101 is less than the distance between the bottom surfaces of the four drive wheels 5 and the bottom surface of the bicycle frame 101. The four drive wheels 5 touch the ground. Then, control the movement and steering of the exercise bike through the touch screen panel. The drive motors 502 and steering servos 503 on the four drive wheels 5 work together to control the synchronous driving and steering of each drive wheel 5, thereby realizing the free movement of the exercise bike in all directions.

[0065] When there is no need to move the exercise bike, tapping the touchscreen 12 exits the moving mode, and the exercise bike enters the stationary mode. The drive motor 502 and steering servo 503 stop working, and the self-locking telescopic device 8 returns to its initial extension distance and self-locks the telescopic rod 802. The distance between the bottom truncated cone 803 of the self-locking telescopic device 8 and the bottom surface of the bike frame 101 is greater than the distance between the bottom surfaces of the four drive wheels 5 and the bottom surface of the bike frame 101. The bottom truncated cone 803 of the self-locking telescopic device 8 is grounded and supported, while the drive wheels 5 are suspended in the air, keeping the exercise bike in a fixed position. This design of the moving device gives the exercise bike flexible movement capabilities and enhances the user's dynamic experience. At the same time, it can also restrict the movement of the exercise bike according to the user's needs.

[0066] For details, please refer to the appendix. Figure 1 Appendix Figure 8 The simulated motion device consists of four motion mechanisms installed at the bottom ends of the front (left) and rear (right) bicycle brackets 101. Each motion mechanism includes a ball head 801, a telescopic rod 802, a self-locking telescopic device 8, and a bottom truncated cone 803 connected in series. The telescopic rod 802 is connected to the bicycle bracket 101 through the ball head 801. The self-locking telescopic device 8 is either on the ground or not on the ground through the bottom truncated cone 803. The input of the self-locking telescopic device 8 is connected to the output of the control unit of the touch screen 12. The control unit of the touch screen 12 outputs a control signal to control the extension and retraction of the self-locking telescopic device 8.

[0067] Before the dynamic mode is activated, the four self-locking telescopic devices 8 maintain / restore the same set extension distance. After the dynamic mode is activated (there are several specific sub-modes to choose from in the dynamic mode), the telescopic rods 802 in the four self-locking telescopic devices 8 extend or retract simultaneously according to the set pattern, by the same or different distances, and after a short pause at a specified time, retract by the same or different distances again, and repeat the above control.

[0068] The specific control methods for simulating various road conditions in Dynamic Mode are as follows:

[0069] When the ramp sub-mode is selected, the two self-locking telescopic devices 8 of the front (note: the front is the front, the rear is the rear) bicycle support 101 will simultaneously extend the telescopic rods 802 to the same height. Because the ball joint 801 at the top of the self-locking telescopic device 8 is connected to the bottom of the bicycle support 101 using a universal ball joint, after the two telescopic rods 802 at the front end extend to a certain height, the bottom frustum 803 of the self-locking telescopic device 8 supports the ground. The telescopic rods 802 remain vertical to the bottom surface and lift the front bicycle support 101. However, the universal ball joint connection structure causes the front bicycle support 101 to rise at a certain angle, followed by the rear bicycle support 101... The two self-locking telescopic devices 8 of 1 also extend the telescopic rod 802 to a certain height, raising the bicycle support 101 at the rear end. Then, the telescopic rod 802 in the two self-locking telescopic devices 8 of the bicycle support 101 at the front end retracts to a certain height, causing the bicycle support 101 at the front end to drop to a certain distance below the rear end. The above process is controlled to cycle repeatedly according to a certain pattern, so as to achieve the alternating and gentle lifting of the bicycle support 101 at the front and rear ends. This makes the user feel as if they are riding on the bottom of an uneven slope, personally experiencing the damping and rhythmic feeling of entering a soft sand pit. At the same time, the touch screen 12 will simulate the corresponding hillside scene, enhancing the user experience.

[0070] When the creek pebble mode is selected, the four self-locking telescopic devices 8 at the bottom of the bicycle frame 101 will individually control the corresponding telescopic rods 802 to extend to the corresponding distance according to the set program and raise and lower the same distance in a regular manner. Since the ball head 801 at the top of the self-locking telescopic device 8 is connected to the bottom of the bicycle frame 101 by a universal ball head, the four ends of the bicycle frame 101 will be lifted to different heights according to the different extension heights of the corresponding telescopic rods 802, so that the bicycle frame 101 can tilt at multiple angles and the overall bicycle frame can be raised and lowered in a regular manner, allowing users to experience riding on a bumpy road surface covered with creek pebbles. At the same time, the touch screen 12 will also simulate the corresponding creek pebble road scene to enhance the user experience.

[0071] When selecting the moving off-road sub-mode, the user first needs to select the center of the movable range and move the exercise bike to this center using the moving mode. Alternatively, the default initial location can be used as the center point of the movable range. After confirming the center point, a circular swinging range can be set based on this center position, and the radius of the movable circle can be set. At this time, the position sensing chip in the exercise bike's touchscreen will set the movable circle range based on the set center point and the corresponding radius. The exercise bike will alternately raise and lower the two self-locking telescopic devices 8 at the front and rear ends simultaneously, so that the two drive wheels 5 at the front or the two drive wheels 5 at the rear touch the ground. When the two drive wheels 5 at the front touch the ground, the drive motor 502 and the steering motor 503 work together to turn to the left and move a certain distance, then turn back to the right and move a certain distance. At the same time, the two self-locking telescopic devices 8 at the rear end will extend, so that the distance between the bottom truncated cone 803 of the two self-locking telescopic devices 8 and the bottom surface of the bike frame 101 is greater than the distance between the bottom surfaces of the four drive wheels 5 and the bottom surface of the bike frame 101. The telescopic rods 802 are extended and retracted in a regular pattern (the extension distance of the two telescopic rods 802 at the rear end is greater than the initial extension distance during the extension process to ensure that the two drive wheels 5 at the rear end are suspended in the air). This allows the front end of the exercise bike to move left and right and sway, while the two rear sides simultaneously rise and fall or alternately rise and fall to form a left and right tilt. The front end of the exercise bike moves in a fan shape within its movable range. When the two drive wheels 5 at the rear end touch the ground, the two drive wheels 5 at the front end are controlled to be turned to the left by the drive motor 502 and the steering motor 503 after they touch the ground, moving a certain distance to the left and then turning back to the right to move a certain distance. The two self-locking telescopic devices 8 at the front end are controlled as described above to keep the two drive wheels 5 at the front end suspended in the air. The two telescopic rods 802 at the front end are controlled to rise and fall simultaneously or alternately according to a certain pattern to form a left and right tilt at the front end. The rear end of the exercise bike moves in a fan shape within its movable range (the fan-shaped movement and swaying of the front and rear ends of the exercise bike are all within the set movable range). Through the above alternating control, users can truly experience the feeling of moving forward in an S-shaped bumpy swaying motion on an off-road road. At the same time, the touch screen 12 will also simulate the corresponding off-road road scene to enhance the user experience.

[0072] By selecting different dynamic sub-modes, the height of the extension rods 802 in the self-locking telescopic device 8 corresponding to the four ends of the bicycle frame 101 can be flexibly controlled and adjusted. The fixed ball head 801 at the upper end of the telescopic rod 802 is used to connect to the bottom of the bicycle frame 101. The extension and retraction are controlled by the self-locking telescopic device 8, allowing the bicycle frame 101 to tilt flexibly in multiple directions with multiple degrees of freedom. At the same time, the drive wheels 5 at the front and rear ends of the exercise bike are controlled to alternately touch the ground and move and sway. When all the front and rear telescopic rods 802 are extended and retracted alternately, the extension and retraction process is controlled to be smooth, enhancing the damping feel of the exercise bike body during multi-directional and multi-angle tilting and vibration. Through the alternating lateral movement of the front and rear ends of the exercise bike and the multi-directional and multi-angle tilting and vibration of the body, combined with the touch screen 12 and the projector 10 simulating the corresponding scene, the user's realistic experience of riding and exercising in various dynamic sub-modes is enhanced.

[0073] For details, please refer to the appendix. Figure 9 The damping adjustment device includes a magnet 304 that acts magnetically on the flywheel 301, an electric telescopic rod 303 that controls the magnitude of the magnetic force exerted by the magnet 304 on the flywheel 301, and a gyroscope sensor installed in the arc-shaped frame 105. The flywheel 301 is a metal wheel that can be attracted by a magnet. The end of the electric telescopic rod 303 is fixedly connected to the vehicle body 1, and the head of the electric telescopic rod is fixedly connected to the magnet 304. The magnet 304 is arranged in an arc shape and concentrically with the flywheel 301, maintaining a certain distance between the magnet and the flywheel. The gyroscope sensor is installed in the middle of the arc-shaped frame 105. The control input of the electric telescopic rod 303 is connected to the output of the control unit of the touch screen 12, and the output of the gyroscope sensor is connected to the input of the control unit of the touch screen 12. The gyroscope sensor is used to monitor the position and posture changes of the vehicle body in real time and send the data to the control unit of the touch screen 12 for processing. When the simulated dynamic mode is selected via the touch screen 12, the control unit of the touch screen 12 responds to the output of the gyroscope sensor and controls the extension and retraction of the electric telescopic rod 303 according to the changes in the posture of the vehicle body, adjusting different damping to achieve the purpose of adjusting resistance. When the normal riding mode is selected via the touch screen 12, the control unit of the touch screen 12 does not respond to the output of the gyroscope sensor, and the user directly selects and controls the extension and retraction of the electric telescopic rod 303 via the touch screen 12 to adjust different damping to achieve the purpose of adjusting resistance.

[0074] In simulated dynamic mode, the gyroscope sensor captures the front and rear tilt state of the vehicle body 1 in real time, providing data on angle changes. The specific control method for adjusting the damping is as follows: when the front side is higher than the rear side, the uphill riding environment is simulated, and the extension length of the electric telescopic rod 303 is controlled. The greater the slope, the smaller the distance between the magnet 304 and the flywheel 301. Thus, under the action of the magnetic field, the greater the slope of the uphill, the greater the resistance for the user to ride.

[0075] When the front side is lower than the rear side, the riding environment is simulated as a downhill slope. The distance of the retracted electric telescopic rod 303 is controlled. The greater the slope, the greater the distance between the magnet 304 and the flywheel 301. Thus, under the action of the magnetic field, the slope of the downhill slope is greater and the riding resistance of the user is smaller.

[0076] For details, please refer to the appendix. Figure 10 The safety protection device includes: a safety air cushion 7, an air pump 6, a pipe 601, and a rotatable bracket 701. The air pump 6 is fixedly connected to the bicycle bracket 101 (on the right side). One air pump 6 is installed on each side. One end of the pipe 601 is connected to the air pump 6, and the other end is connected to the safety air cushion 7. There are two safety air cushions 7 in total, distributed on the bottom of both sides of the bicycle. One safety air cushion 7 is connected to each of the two sides of the lower part of the rotatable bracket 701. When the motion-sensing mode is activated, the air pump 6 operates to rapidly inflate the safety air cushion 7 through the pipe 601 until the safety air cushion 7 is fully expanded (the air pump 6 automatically shuts off when the air pressure inside the air cushion reaches a certain level). (See attached diagram.) Figure 2In non-moving mode, the extension distance of the telescopic rods 802 at the bottom of the four ends of the bicycle bracket 101 is not less than the initial extension distance. At this time, the bottom surface of the safety air cushion 7 is in contact with the ground after it is fully deployed. It forms a rotating pair through the cooperation of the rotatable bracket 701 and the hinge-type fixed connector 104. When the bicycle bracket 101 tilts strongly to the left or right in dynamic mode, the safety air cushion 7 will not tilt with the bicycle bracket 101 because the bottom surface of the safety air cushion 7 is in contact with the ground after it is expanded and connected to the bicycle bracket 101 by the hinge-type rotating pair. It remains in contact with the ground. When the bicycle frame 101 tilts forward or backward in Dynamic Mode, the air cushion 7, with its flexible bending and pressure resistance, and the curved frame 105 at the bottom of the bicycle frame 101, minimizes the pressure on the air cushion 7 during tilting. This ensures that the air cushion 7 remains in contact with the ground during multi-degree-of-freedom tilting of the bicycle frame 101. This provides timely protection for the user during a fall in Dynamic Mode, preventing injury. When Dynamic Mode is turned off, the air pump 6 depressurizes the air cushion 7 through pipe 601 until it retracts back to its original position (the air pump 6 automatically shuts off when the air pressure inside the air cushion drops to a certain level). The air pump 6 corresponding to the air cushion 7 can be controlled in three ways: first, individually via the touchscreen 12; second, automatically activated upon entering Dynamic Mode; and third, directly controlled by the switch on the battery 4. The third method involves a separate control switch for an air pump 6 on the battery 4. Before a user with a height disability gets on the bike, they can press the switch to directly control the air pump 6 to run until the safety air cushion 7 is fully inflated and opened. At the same time, each time the exercise bike is turned off, the seat lifting bar 202 will retract to its lowest position. Users with a height disability can step on the fully inflated safety air cushion 7 as a step to sit on the exercise bike seat 2. After sitting down, the exercise bike can be started, and the air pump 6 can be controlled to inflate and deflate the safety air cushion 7 and adjust the height of the seat 2 via the touch screen 12.

[0077] Specifically, other auxiliary accessories include: a solar panel 9, a projector 10, a phone holder 13, and a cup holder 14. The solar panel 9, installed at the front of the bicycle, collects sunlight to charge the bike, reducing reliance on external power. The projector 10, mounted at the front, can play various content such as movies, music, and games by connecting to smart devices or using the built-in storage. The phone holder 13, fixed to the front of the bicycle, includes a charger port, allowing users to place their phones and plug them into the USB port on the holder 13 for charging and data transmission via the battery 4, providing a better riding experience. The cup holder 14, installed at the curved front of the bicycle, allows users to stay hydrated and maintain fluid balance for better exercise. These auxiliary accessories provide a more comprehensive exercise experience and enhance the bicycle's functionality and practicality.
