3 Terms and definitions
For the purposes of this document, the following terms and definitions apply. 3.1 Electrical self-balancing vehicle
A wheeled manned mobile platform that is based on the inverted pendulum model and the principle of static instability, and is equipped with a rechargeable electric drive system, thus maintaining dynamic balance in an autonomous or manual mode of operation.
NOTE. The electrical self-balancing vehicle is referred to as the self-balancing vehicle for short. 3.2 Safety alarm
An alarm that may be clearly noticed by the user after being sent to the user, when an electrical self-balancing vehicle detects internal faults (such as abnormal battery voltage, balance control unit failure) or dangerous driving actions or abnormal working conditions of the vehicle.
3.3 Footrest tilting function
The function enabled for limiting the user to continue driving in case of overspeed, low-battery driving or overload driving detected in an electrical self- balancing vehicle, thus protecting the safety of the user, by automatically tilting up the front end of the footrest on the self-balancing vehicle.
3.4 Enclosure
A component of the equipment with one or more of the functions specified in 3.5, 3.6, 3.7 or 3.8.
NOTE. One type of enclosures may be inside another type of enclosures (for instance, an electrical enclosure is inside a fire enclosure, or a fire enclosure is inside an electrical enclosure). In addition, one type of enclosures may provide the functions of multiple types of enclosures (for instance, with the functions of both electrical enclosures and fire enclosures).
NOTE. REWRITE the definition in 1.2.6.1 of GB 4943.1-2011.
3.5 Fire enclosure
A component of the equipment, which is designed to minimize the outbreak of fire or spread of flames in the equipment.
[Definition in 1.2.6.2 of GB 4943.1-2011]
3.6 Mechanical enclosure
A component of the equipment, which is designed to reduce the risk of damage caused by mechanical and other physical hazards.
[Definition in 1.2.6.3 of GB 4943.1-2011]
3.7 Electrical enclosure
5.3 Sharp edges
Tubular objects that may cause stab injuries to the users on the outside of the electrical self-balancing vehicles or hard protrusions of equipment components shall be adequately designed (such as obtuse angle design, etc.) to guard against stab injuries to the human bodies.
For threads that may pose a risk of stabbing, the length of the thread beyond its internal attachment shall be limited to the length of a thread outside diameter. 5.4 Safety protection functions
5.4.1 Overspeed protection
The electrical self-balancing vehicle shall have such protection functions as continuous safety alarm beyond the speed limits and continuous tilting function or the like, so as to restrict the user from continued acceleration, thus protecting user safety.
5.4.2 Low-battery protection
The electrical self-balancing vehicle shall be capable of providing low-battery protection, that is, when the power of the electrical self-balancing vehicle?€?s battery pack is lower than the minimum power required by the manufacturer for safe driving, the self-balancing vehicle shall have such protection functions as continuous safety alarm and continuous tilting function or the like, so as to restrict the user from continued driving.
5.4.3 Grade parking performance and protection
The electrical two-wheeled self-balancing vehicle shall have grade parking performance and protection function. After tested ...
