一款世界上最省力的旅行箱

一款世界上最省力的旅行箱 　　The first of its kind, this is the self-propelled suitcase that automatically provides power assistance when you encounter inclines or are straining to roll the suitcase. 　　这是一款首创的自助式行李箱，它能够在你拉它上坡或者感到吃力时助你一臂之力。 　　Sensors in the handle monitor how much force you are using to pull the suitcase and signal to electric motors in the wheels to engage when you are struggling, propelling the suitcase up to 3 miles per hous. 　　箱子拉杆内置的传感器可检测出你拉箱子所用力的大小，当你拉起来费劲时，传感器会向滚轮内的马达发送运转信号，使马达以3英里/小时的速度推动箱子前进。 　　The power assistance initiates only when the suitcase is in motion, the handle is pulled out from the suitcase, and it is tilted between 15°and 35°. 　　这种助力只会在箱子满足以下条件时产生：箱子在拉动过程中，拉杆拉出，且倾斜度介于15°到35°之间。 　　When you encounter declines, the motors disengage, allowing you to control the unit normally. The handle and suitcase are designed so that 85% of the carried weight is transferred to the wheels, reducing your load. 　　在你下坡时，马达不产生助力，使你能够正常地控制这个箱子。由于拉杆和箱子的设计，85%的箱子重量都转移到了轮子上，从而减轻了你的负担。 　　The suitcase is made from injection molded polycarbonate composite--the same material used in automobile bumpers--that provides superior impact protection. There must be at least 15 lbs. in the suitcase for the power assistance to operate; and it can hold up to 70.5 lbs. 　　箱子采用注塑成型的聚碳酸酯复合材料制造而成，该材料与汽车保险杠的制造材料相同，可提供很好的防撞保护。箱子启动助力所需的最小重量是15磅，最大承重70.5磅。
