Hoverboard in the past may looked like something from a science fiction movie, now became reality. Consumers already have the opportunity to acquire this futuristic toy that looks like very close to those ideals from Hollywood. Self-balancing scooters, or more known by hoverboard, is a levitating platform used for personal transportation.
Basically it is a rechargeable battery-powered scooter, consisted of two wheels arranged side-by-side, with two small platforms between the wheels, on which the rider stands. The device is controlled by the rider’s feet, standing on the built-in gyroscopic sensored pads.
The increase of popularity may call attention to manufactures expand their production levels, but the actual scenario calls for some attention. Recently there has been a spate of incidents concerning exploding hoverboards across many countries.
Facing all incidents already reported, as you can read it here, regulators started to look at the products more critically, but in general there is not yet a common consensus on standards and regulated safety standards, what forces manufacturers take a special attention on their quality control program, facing the security responsibility on their hands.
Hoverboard Parts and Components
1. Structure and Shell
A steel frame with a central pivot is responsible for support the user weight above all other electronic parts, as well as being the axle between the wheels. Hardness and elastic resistance are key quality parameters, to prevent mechanical failures due impact.Also important on the inspection of this part, dimensions and tolerances, as it will be the focus point on assembling all others parts together.
After that, an external plastic shell gives design and some extra protection to electronics parts, especially against environment conditions such as wind or rain. Some hardness also should be certified, as it should resist to a certain level of impact.
In both cases the quality of raw material is crucial, for provide acceptable mechanical characteristics.
Each wheel stores an electric motor, besides a tilt and speed sensor. It detects the rpm speed from the individual wheel, sends it to the gyroscope and speed control boards, located inside the main body, right next to the wheels.
As a moving part connected to different devices together, being suitable of external impacts, the wheels should be correctly assembled and materials proprieties should be ensured, providing so reliability during the use.
Further more practical tests are recommended in order to analyze the operating performance of the wheels, and detect potential risks related to assembly with other parts.
3. Controlling and Logic boards
The signal is sentto the main logic board, that is the “brain” of the device, and it’s where the processor computes in real time the status of the board, the speed at which you’re travelling, and the relative speed and tilt of the individual wheels.
Just like most of electronic boards, soldering conditions, quality of connections, sourcing conditions and key testing procedures are important measures about these parts.
In a hoverboard defects on boards may cause several issues, since incorrect response to the commands sent, until acomplete unable functioning of the scooter.
4. Battery Pack
The battery pack is what keeps your board going, containing besides the battery itself, an AC Charger and connections linking it to the motor. Battery comprises 20 cells of 2200 mAH to make a 4.4 Amp in general. For security reasons, the connections should have a kill switch, when the battery temperature gets to a certain risk level, which is the main cause for most of all fire incidents reported.
Hoverboards use lithium ion battery packs, and the liquid swimming around inside this type of battery is highly flammable. If the battery short-circuits, the liquid electrolyte can heat up so quickly that the battery explodes. Considering in terms of safety, and so the most important part to be certified, special attention to its quality control approach must be taken.
First of all the properly selection of reliable and duly certified suppliers is a fundamental premise. Also execute charge and discharge tests should be imperative in order to ensure not only the life cycle promised, but also a preventative verification for the risk of overheating and consequently fire incidence.
Inspection Services for Hoverboard in China & Asia
Our services may offer the right solution for each phase and strategy of a Hoverboard manufacturing process quality control. Regarding the battery, maybe the most critical part due all safety risks mentioned, it is critical to ensure if the sourcing for that is on properly conditions.
Manufacturers must have the correct certificates and licenses in place, in addition to appropriate manufacturing conditions. Our Suppliers Audit Solutions in Asia can help you at affordable cost to verify the profile of your vendor before sending your deposit.
For a small cost, it provides enough information to have already a general understanding of your source. This approach could also be extended to all others sourced parts, like boards and sensors, for example. Additionally an Incoming Material Inspection would ensure a complete reliability approach regarding quality control of outsourced materials.
Chances of error and defects are still suitable during the production, so Production inspection in China Solutions for other phases , which focus on the product itself regarding expected requirements of quality parameters and manufacturing conditions: conformity, appearance, test, packing, packaging, dimension, weight, marking, accessories, weight, etc.
Issues like an incorrect shell, assembly errors of the frame or a loose wheel could be at this point detected in a preventive way, saving costs and resources.
Challenges of a promising market
If in one hand the hoverboard already became the object of desire of thousands of people around the world, thus making this a market with significant growth potential, on the other we face a scenario of a fairly new technology, not yet fully dominated by manufacturers.
But before that, and perhaps more urgently, it places a great responsibility on ensuring a reliable quality control for their products.
The lack of clear rules makes this task even more difficult to be achieved, but the services offered by Asia Quality Control will surely help you in this challenge, and so allow you to enjoy the many opportunities from this promising segment.
