手持式电钻相关专利技术情况进展

Patent Technology Progress of Hand-held Electric Drill

手持式电钻是电动工具大类中最常见的产品之一,研究其相关技术进展情况对于行业发展至关重要。通过专利检索技术,统计专利信息,对手持式电钻的专利申请现状、技术领域及技术层级进行分析,预测其技术热点。发现手持式电钻相关专利的申请量呈现上升趋势,其中中国占比最大,但其多边专利申请情况较为不足;手持式电钻相关专利技术中的机械结构中的连接件、防尘罩、电钻夹头以及附加结构中的多功能技术发展趋势较好,是近五年的研究热点。

Hand-held electric drill is a major kind of electric tool,which is often used.Therefore,it is very important for the development of the industry to study its related technology progress.The patent application status,technical field and technical level of hand-held electric drill are analyzed through patent search and patent information statistics,and the hot spot of technology is predicted.The number of patent applications related to hand-held electric drill is increasing rapidly,which shows that China is the first,but its multilateral patent application is lagging behind.The connector,dust cover and electric drill chuck technology in mechanical structure and the multi-functional technology in additional structure in patent technology of hand-held electric drill are research hotspots in recent five years.
