What does the Interior of a hoverboard look like?
You always see a good looking board that has a beautiful cover of your preferred color, but you have never seen the inside structure. Have this opportunity to have a look at the interior fabric of an electronic scooter. Below is a detailed picture showing the internal parts of an electric scooter.
These are the internal features
• Steel frame with a central pivot
• Logic board
• Two tilt/speed sensors
• Charging port
• Two gyroscopes
• Two infrared sensors
• Two electric motors
• Power switch
• A battery pack
• LED lights
• Pressure pads
• A plastic shell
Q1 How does a hoverboard move?
The movement of a hoverboard is facilitated by the wheel sensor, speed controls board, main logic board, and the battery pack
The Wheel Sensor
The electric motors that are responsible for the movement is housed within the wheels. Within the wheels are tilt and speed sensors. Each wheel, therefore, detects the rpm (revolutions per minute) and sends the signal to the gyroscope and speed control boards that are located inside the main body, just next to the wheels.
Gyroscope / Speed Control Boards
The gyroscope and speed control boards are responsible for detecting the rpms and tilt information from the sensor located inside the wheels. After receiving the information, they send it to the main logic board. When you calibrate your board, the gyroscopes are basically “zeroed”, this shows that you’re telling the gyroscopes, “this is flat; hence that is when we say the hoverboard’s tilt is at 0.” Therefore, the speed control boards are necessary to receive, convert, and relay the signals from the wheel sensors to the main logic board.
The Main Logic Board
The logic board can is comparable to the brain of a human being; therefore, it is the “brain” of your hoverboard. This is where the processor computes in real time the status of the board, for instance, the speed at which you are travelling, and the relative speed and tilt of each wheel. For example, when you turn the two wheels, they would have opposing tilts, and hence opposing rpms and motion. Power management controls also take place in the main logic unit, thus, “beginner mode” that limits the max speed or “locked” mode to lock the scooter.
The Battery Pack
Your board moves with the aid of the charged battery. Therefore, the battery pack is what keeps your scooter going. There are various packs for different boards, but the vast majority of scooters operates on 36V 4400mAH battery packs. All the other processes depend on the presence and functionalism of the battery pack. Care for the battery pack is recommended including the charging and battery replacement procedures.
Q2 How does a Hoverboard detect your movement?
Many people have just been imagining and never found the real answer on how the scooter detects the movement of the body. The movement of the body is detected once you are on top of the board, and it entails series of processes.
Below each foot pad is pressure pads that rests on two switches each.
When you lean forward, the front switch is pressed down, and a little plastic “wall” slides in-between an infrared sensor and infrared LED.
When the sensor detects the light, the logic board communicates the signal to the motors to be still. But when the light is interrupted (as a result of the switch being pushed down by your weight), the board commands the motor to spin in a given direction. For instance, if you are turning right, your foot activates the front left switch, making the left wheel spin forward, while your right foot activates the back right switch, making the right wheel spin backwards. This will result in the scooter turning to the right.
To summarize the information given, the tilt sensors in the wheels informs the gyroscopes on how far forward you are leaning. The gyroscopes then relay the same information to the logic board. The more you lean forward, the faster the logic board informs the motors to spin, to sort of “catch up” with your center of gravity. This is a simple mechanism that allows you to control the riding speed of the scooter with your weight. That summarizes the science behind the movement and controlling of hoverboards using your weight.
