AI Technical Summary
Technical Problem
[0005]现有的电动齿轮箱做不到手自一体模式，即只能采用电动方式驱动齿轮箱运转，一旦电动齿轮箱中的电机或传动系统发生故障时，使用者较难使用手动操作的方式来驱动齿轮箱运转，户外遮阳伞就无法使用，因此使用较为不便，而且实用性也不强；即便通过手动操作的方式能勉强驱动齿轮箱运转，但是会迫使电机或传动系统被动转动，极易造成电机或传动系统的不可逆损坏，使用可靠性欠佳，有待于进一步改进
Benefits of technology
[0017]本实用新型采用了手自一体模式，既能通过手动方式驱动主动杆旋转，又能借助电动模块自动驱动主动杆旋转，一旦电机或传动组件发生故障时，户外遮阳伞仍然可以正常使用，进而大大方便了使用，同时有效增加了实用性；同时还配备了离合模块以有效防止电机被动转动，进而避免对电机造成不可逆的损坏，从而显著提升了使用可靠性。
