[0026] Reference Figure 1-4The utility model provides an embodiment: a simulated adjustable dynamic bicycle, comprising a bicycle body 1, an antistatic plastic plate 2 is arranged on the bottom surface of the bicycle body 1, a non-standard connector 3 is arranged on the bottom surface of the antistatic plastic plate 2, a universal joint 4 is arranged on the bottom surface of the non-standard connector 3, a top screw 5 is arranged on the inner side of one side surface of the universal joint 4, an electric push rod 6 is arranged on the bottom surface of the universal joint 4, a motor 7 is arranged on the lower part of one side surface of the electric push rod 6, a bracket 8 is arranged on the bottom surface of the electric push rod 6, a pin 9 is arranged on the inner side of one side surface of the bracket 8, a steel plate 10 is arranged on the bottom surface of the bracket 8, a hexagonal nut 11 is arranged on the top surface of the antistatic plastic plate 2, the inner bottom surface of the bracket 8 and the bottom surface of the steel plate 10, a gasket 12 is arranged on one side surface of the hexagonal nut 11, and a bolt 13 is arranged on the inner side of the hexagonal nut 11 on the bottom surface of the steel plate 10.

[0027] The bicycle body 1 and the antistatic plastic plate 2 are inlaid and connected, and the antistatic plastic plate 2 is a rectangular parallelepiped. The antistatic plastic plate 2 and the steel plate 10 as well as the bracket 8 are threadedly connected with the hexagonal nut 11 and the gasket 12, and the hexagonal nut 11 and the gasket 12 are spliced ​​and assembled.

[0028] The hexagonal nut 11 and the non-standard connector 3 are threadedly connected, and the non-standard connector 3 is arranged in three groups and arranged in a triangle shape. The non-standard connector 3 and the universal joint 4 are threadedly connected, and the universal joint 4 is arranged in three groups.

[0029] The universal joint 4 and the top screw 5 are threadedly connected, the universal joint 4 and the electric push rod 6 are threadedly connected, the electric push rod 6 is arranged in three groups, the electric push rod 6 and the motor 7 are fixedly connected, and the bracket 8 of the two push rods of the electric push rod 6 and the connecting line of the two push rods are arranged at an angle of 30 degrees.

[0030] The electric push rod 6 and the bracket 8 are connected and fixed by a latch 9. The inner side of the middle part of the bracket 8 is provided with a hollow groove. The bracket 8 and the steel plate 10 are connected and fixed by bolts 13, hexagonal nuts 11 and washers 12.

[0031] Specifically, the structure is composed of a bicycle body 1, an anti-static plastic plate 2, a non-standard connector 3, a universal joint 4, a top screw 5, an electric push rod 6, a motor 7, a bracket 8, a latch 9, a steel plate 10, a hexagonal bolt 11, a gasket 12 and a bolt 13 to form a simulated adjustable dynamic bicycle. The simulated adjustable dynamic bicycle is designed by improving the design of the dynamic bicycle body, designing a shaking and vibration simulation system, and producing a new type of interesting smart dynamic bicycle. The MPU6050 chip is installed on the handlebar of the bicycle body 1 to measure the acceleration and angular velocity to obtain the rotation angle, and the data is transmitted to the single-chip microcomputer, and the lifting speed of the motor 7 controls the lifting and lowering of the electric push rod 6 and the tilting mode of the anti-static plastic plate 2. When going uphill and downhill, three electric push rods 6 control the antistatic plastic plate 2. The flywheel inside the bicycle body 1 uses magnetic resistance to adjust the resistance. The riding frame is the main part of the bicycle body 1, which is made of materials such as aluminum alloy, steel and plastic. It has high strength and durability, and also has anti-skid and anti-sweat characteristics. The seat is an important part of the bicycle body 1 and can be adjusted according to the height of the user. The seat is usually composed of durable sponge material and anti-sweat leather material. Through the magnetically controlled flywheel of the bicycle body 1, people can turn the flywheel by pedaling. The flywheel is controlled by electromagnetic sensors and motors 7, and can change the resistance according to different road surfaces to provide a real riding experience. The pedals of the bicycle body 1 are made of durable plastic materials, which are both light and strong enough, and also have good anti-skid and anti-sweat properties, so that users can be more comfortable and safe when riding. The handle of the bicycle body 1 is made of foam and rubber, which is soft and anti-skid, and can relieve hand fatigue. There is an angle sensor inside the handle, which is responsible for transmitting the handle rotation angle data to the applet. An antistatic plastic plate 2 is welded under the bicycle body 1, and a lifting component is arranged under the antistatic plastic plate 2. The lifting component is mainly composed of three electric push rods 6, and the motors 7 of the three push rods are all controlled by a single-machine module of a single-chip microcomputer. The lifting component connection assembly is formed by non-standard connectors 3, universal joints 4, top screws 5, electric push rods 6, motors 7, brackets 8, latches 9, steel plates 10, hexagonal bolts 11, gaskets 12 and bolts 13, so that the whole can prevent loosening, provide support, lower the center of gravity, and connect firmly, ensuring safety and stability. The universal joint 4 realizes variable angle power transmission, provides two degrees of freedom, and tilts the antistatic plastic plate 2. The electric push rod 6 converts the rotational motion of the motor 7 into linear reciprocating motion, and realizes the height difference of each part of the antistatic plastic plate 2. The motor 7 provides power for the electric push rod 6, and the latch 9 connects the bracket 8 and the electric push rod 6, and provides one degree of freedom, so that the whole can effectively improve the user's power and fun to use for exercise.

[0032] Working principle: fix the MPU6050 chip on the handlebar of the bicycle body 1, connect the chip to the single-chip microcomputer that controls the push rod motor 7, read the data, and record it, program the single-chip microcomputer, control the lifting and lowering of the electric push rod 6, and adjust the tilt mode of the anti-static plastic plate 2. According to the positive and negative input voltages of the adjustment motor 7, control the rotation direction of the motor 7, set the timing value of the timer to a fixed value according to the telescopic direction of the electric push rod 6, and control the movement of the electric push rod 6 by changing the movement speed of the electric push rod 6. Three points determine a plane, so three electric push rods 6 are used to control the anti-static plastic plate 2. The electric push rod 6 is an actuator that combines the motor 7 and the push rod. In its work, the motor 7 drives the worm to rotate through the transmission device, and the worm drives the push rod to rotate. The electric push rod 6 realizes movement through the load connected to the push rod. The working principle of the electric push rod 6 is to convert electrical energy into mechanical energy, realize the transmission of force and the movement of the actuator, so that the whole has the advantages of simple structure, smooth movement, and high transmission efficiency. The flywheel inside the bicycle body 1 adopts a magnetic resistance method, which increases resistance when going uphill and reduces resistance when going downhill. The principle of magnetic resistance is to use the magnetic lines of force generated by the electromagnet to form a magnetic field on the flywheel, hindering the rotation of the flywheel, thereby achieving the purpose of adjusting the resistance. The magnetic resistance system of the bicycle body 1 includes a controller, an electromagnet and a flywheel, and the current of the electromagnet is controlled by the controller. When the current increases, the magnetic lines of force of the electromagnet will also increase, thereby strengthening the magnetic field on the flywheel and hindering the rotation of the flywheel. Conversely, when the current decreases, the magnetic lines of force of the electromagnet will also weaken, thereby weakening the magnetic field on the flywheel and reducing the resistance. By accurately controlling the magnitude of the current, the magnetic resistance system of the bicycle body 1 adjusts the resistance.

[0033] like Figure 4 As shown, the specific operation mode of the electric push rod 6 is: when going uphill, No. 1 rises to the highest position, and No. 2 and No. 3 fall to the lowest position. If the handle is rotated to the left, the height of No. 3 push rod changes and gradually rises, and the change amount is proportional to the handle inclination angle; if the handle is rotated to the right, the height of No. 2 push rod changes and gradually rises, and the change amount is proportional to the handle inclination angle. When going downhill, No. 1 falls to the lowest position, and No. 2 and No. 3 rise to the highest position. If the handle is rotated to the left, the height of No. 2 push rod changes and gradually decreases, and the change amount is proportional to the handle inclination angle; if the handle is rotated to the right, the height of No. 3 push rod changes and gradually decreases, and the change amount is proportional to the handle inclination angle. When encountering uneven road sections, the vibration mode is adopted, and the three rods are alternately lowered by 5cm and then raised by 5cm in sequence.
