Description

Parallel device of two-wheeled vehicle using gyroscope}

This utility model was designed to maintain the balance of the two-wheeled vehicle using a gyroscope to prevent the two-wheeled vehicle from tilting or falling due to gravity when running on time.

A gyroscope (English: gyroscope) is a top that is completely symmetrical top and bottom, is made in a direction perpendicular to the axis of the top using a ring, then held in a direction perpendicular to the previous one using a second ring, and then placed again on a third ring. It is a device that allows the top to rotate in any direction by supporting it in a direction perpendicular to the first two. It is an instrument used to measure or maintain direction.

A gyroscope is a rotating wheel whose axis can be positioned in any direction, a mechanism consisting of a rotor and a gimbal, and is based on the law of conservation of angular momentum. When a gyroscope rotates quickly, when external torque is given, its direction changes much less than when it is not rotating due to the angular momentum caused by rotation. Since the gyroscope is placed on a gimbal, which is a leveling device, external torque is minimized, and its direction is almost fixed even if the mounted base moves.

This is due to rotational inertia moment, a type of inertial force. In other words, it is a method of maintaining the balance of a two-wheeled vehicle by using its tendency to maintain rotation once it starts spinning.

According to this physical principle, a top-shaped gyroscope is mounted on the main body of the bicycle, and the axis of the gyroscope is rotated by the power of the motor, so that the bicycle is balanced according to the physical principles of the rotating flywheel.

This utility model consists of a gyroscope, a sense that measures the speed of the wheels and detects the operation of the two-wheeled vehicle when it moves, a motor that turns the axis of the gyroscope, and a battery unit to drive these devices.

In physics, precession refers to the phenomenon in which a rotating object shakes back and forth when a turning force acts on the rotating rigid body. The most common example of precession is that when spinning a top, the rotation speed decreases and the axis itself spins rather than rotating around the axis of the top.

Not only a top but also any object that rotates around a specific axis can undergo precession on Earth where gravity acts. When a spinning top precesses, the rotation axis of the top rotates in the opposite direction to the direction of rotation of the object. If the rotational speed and the rotational force acting during precession are constant, the speed at which the axis moves continues to be perpendicular to the rotational force and the angular velocity (direction of the rotational axis), and the trace drawn by the rotating axis becomes a cone.

The rotational movement of a spinning top is centered around the rotation axis. If an external force is applied to the top or the top tries to stop on its own over time, it can be observed that although the top is rotating around its axis, the rotation axis also rotates in a constant circular trace.

If the external force interfering with the rotational movement is large, the top will stop, and if it is small, the top will regain its center and rotate. This phenomenon is defined as precession.

This precession is based on the law of conservation of angular momentum. According to conservation of angular momentum, only the direction of angular momentum can change, and the change in this direction is equal to torque, so precession occurs.

If the gyroscope's axis is not perfectly oriented toward gravity and is slightly tilted, gravity will pull on the gyroscope to tip it over. This force acts as a torque to turn the center of gravity downward around the lower end of the gyroscope. However, the gyroscope does not fall over in the tilted direction, but only rotates on the tilted axis.

If this principle is applied to a two-wheeled vehicle, the two-wheeled vehicle can be parallel to the ground even in a stationary state due to the mobility of the gyroscope.

This device uses this

This utility model maintains parallel to the ground when running or has similar mobility due to the characteristics of a two-wheeled vehicle, but provides a device to overcome the phenomenon of falling to the ground under the influence of gravity when the two-wheeled vehicle stops or loses its momentum. There is a purpose of this utility model.

The above objective of this utility model is achieved by detailed devices attached to a two-wheeled vehicle.

The details of this utility model consist of a speed sensor mounted on the front or rear wheels, a gyroscope attached to the luggage compartment of a two-wheeled vehicle, and the motor part that drives the gyroscope.

In other words, the speed of the two-wheeled vehicle is measured through a speed sensor mounted on the central axis of the front or rear wheels.

Depending on the change in momentum, the state before stopping or before starting is detected and a signal is sent to the motor, and the gyroscope mounted on the luggage compartment of the two-wheeled vehicle rotates according to the detected signal.

The rotating gyroscope maintains the luggage compartment of the two-wheeled vehicle in the same direction as the rotation direction of the gyroscope due to the gyro effect, and this effect prevents the two-wheeled vehicle from falling over.

The speed sensor located at the center of the rotating wheel of the two-wheeled vehicle detects the rotation of the wheel and operates to drive or stop the gyroscope according to the transmitted rules, and the battery and drive motor located in the center of the luggage compartment provide the force by a pulley. A belt connected to a gyroscope is operated.

The gyroscope, which receives power from the motor, rotates or does not rotate according to the operation of the sensor.

When there is no momentum of the two-wheeled vehicle, the gyroscope rotates, and when there is momentum from the two-wheeled vehicle, the gyroscope stops working.

The effect of such a mechanical device is to prevent the two-wheeled vehicle from falling, and this practical design is a practical example of how to attach this device to a two-wheeled vehicle.

Detailed information regarding the purpose and technical structure of this utility model, as well as its operational effects, will be clearly understood by the following explanation referring to the drawings showing preferred embodiments of this utility model.

Figure 1 is a representative diagram of the utility model.

Figure 2 shows an example of installation of a speed sensor.

Figure 3 shows the driving motor and power supply unit.

Figure 4 is an example of installation of a gyroscope showing the gyro effect.

As shown, this utility model explains a device that operates a drive motor by a speed sensor and produces a gyro effect accordingly.

As seen above, this utility model prevents falls on two-wheeled vehicles, and this utility model can be effectively used by people who want to learn to ride two-wheeled vehicles or those who have a vague fear of two-wheeled vehicles.

This will be an example of a model that can be widely used commercially.

This utility model is described in detail with reference to the attached drawings as follows.

Drawing 1 is an overall representative diagram and shows an example of installation for this utility item.

In other words, a disc to detect speed is installed on the drive shaft of a two-wheeled vehicle, and this disc is divided into a part where the speed sensor detects, a part where the drive motor is installed to receive the signal detected by the speed sensor, and a part where the gyroscope is installed.

In this state, the representative diagram in Figure 3 is the part where the speed sensor is mounted. This part recognizes the speed according to the rotation of the mounted circle, and the recognized signal is transmitted to the drive motor.

As shown in Figure 3, the power of the drive motor is transmitted by a belt installed together, and this power drives the central axis of the gyroscope.

The gyroscope that begins to rotate produces a gyro effect, and due to this effect, the two-wheeled vehicle becomes parallel to the ground.

In addition, the ratio of the weight and gyro effect that takes into account the weight of the two-wheeled vehicle, cargo, and passengers can be used by creating a specification table.

It can be used on all two-wheeled vehicles with slight modifications depending on the purpose.
