Keywords: electric scooter, safety technology, braking system, anti-skid design, electromagnetic lock

abstract

Safety is the core of electric scooter design. This article analyzes the technical solutions and standard requirements from braking performance, anti-skid structure to anti-theft system.

5.1 Comparison of Braking Systems

Electronic Brake (E-ABS):

By reversing the motor to generate electromagnetic resistance, the braking distance is 3 meters (initial speed of 25km/h), but the efficiency decreases by 20% at high temperatures (requiring the use of heat sinks).

Mechanical disc brake:

Using a 160mm floating disc and opposing four piston calipers, the braking distance is 2.5 meters, but the weight increases by 0.8kg (such as the 9th F60 model).

Energy recovery braking:

Combined with FOC control, kinetic energy is converted into electrical energy, resulting in a 10% increase in range (such as a 15% recovery efficiency for the Little Cow MQiL).

5.2 Anti slip design technology

Tire material:

Adopting silicone composite tread (hardness 60 Shore A), the wet and slippery road grip is improved by 30% (such as Michelin City Grip tires).

Pattern design:

Through Ansys LS-DYNA simulation, the V-shaped groove (depth 3mm, width 2mm) was optimized, resulting in a 50% increase in drainage volume.

5.3 Anti theft system scheme

GPS+Beidou dual-mode positioning:

Adopting U-Blox M8N module, with a positioning accuracy of ± 2m, and a range of 30 days in low-power mode (such as the ninth E100 model).

Electromagnetic lock:

Drive the lock tongue with a 12V DC motor, with a locking force greater than 500N, and use an APP for remote unlocking (such as Xiaomi electromagnetic lock response time<1s).

5.4 Lighting and Warning System

Automatic headlights:

Detecting environmental illumination through photoresistors (such as GL5528) Automatically turn on the LED headlights at 10lx (brightness of 500lm).

cornering lamp:

Adopting flexible light strips (thickness 1mm) with a lifespan of over 50000 hours, supporting flowing light effects (such as Inokim Light 2 model).

5.5 Safety Standards and Certification

EN 17128 standard:

Require braking distance<4 meters (initial speed of 25km/h), handle vibration<5m/s 2, and folding mechanism lifespan>10000 times.

UL 2271 certification:

For the battery pack, it is required to pass tests such as drop (1.5m), impact (10J), and over discharge (0V) to ensure no leakage/fire.

conclusion

Security technology needs to shift from "passive protection" to "active warning". By optimizing braking, anti slip design, and intelligent anti-theft, the safety of user travel can be significantly improved.
