摘要

从环境中回收动能主要集中在自然环境中,而人类生活环境中也蕴藏着巨大的能量。平开门是人类生活环境中不可或缺的设备。门在开关过程中的双向摆动蕴含着丰富的人体运动产生的能量,因此具有很大的能量回收潜力。本文提出了一种用于回收建筑物门双向动能的能量收集器,并对其进行了制作、分析和测试。能量收集器由平行曲柄滑块机构、传动机构和发电模块组成。外部连杆用于连接门和能量收集器,以传递门的双向摆动。平行曲柄滑块机构与两个单向轴承耦合。这可以实现将门的双向摆动转换为中心轴的单向旋转。最终实现机械整流效果。我们进行了运动学和动力学分析,以确定影响发电性能的因素。制作了一个原型,并通过模拟门的打开和关闭过程对其进行了实验。实验结果与模拟结果一致。在正常打开速度为 90° s-1 时,收割机的最大开路电压为 7.06 V,平均输出功率为 1.03 W。回收的能量可为智能门锁供电至少 150 秒,还可为门灯和门铃等设备供电。这可以满足人类生活中大多数门上电子设备的供电需求。

Recovering energy from door opening and closing process using a parallel crank-slider harvester in buildings
Recovering kinetic energy from the environment is mostly focused on the natural environment, while there is also a huge energy in the human living environment. The swing door is an indispensable equipment in the human living environment. The bidirectional swing of the door opening and closing process is rich in energy generated by human motion and thus has a large potential for energy recovery. An energy harvester for recovering bidirectional kinetic energy of the door in buildings is proposed, fabricated, analyzed, and tested. The energy harvester consists of a parallel crank-slider mechanism, a transmission mechanism and a power generation module. The external linkage is used to connect the door and the energy harvester to transmit the bidirectional swing of the door. The parallel crank-slider mechanism is coupled with two one-way bearings. This can realize the conversion of the bidirectional swing of the door to the unidirectional rotation of the central shaft. The final mechanical rectification effect is achieved. Kinematic and dynamic analyses are performed to determine the factors affecting the power generation performance. A prototype is fabricated, and experiments are conducted on it by simulating the process of opening and closing the door. The experimental results are consistent with the simulation ones. At a normal opening velocity of 90° s−1, the maximum open-circuit voltage of the harvester is 7.06 V and the average output power is 1.03 W. The highest efficiency of the harvester can reach 69.65%. The recovered energy is capable of powering the smart door lock for at least 150 s, as well as powering devices such as door lights and doorbells. This can meet the power supply needs of most electronic devices on doors in human life.

期刊介绍: Smart Materials and Structures (SMS) is a multi-disciplinary engineering journal that explores the creation and utilization of novel forms of transduction. It is a leading journal in the area of smart materials and structures, publishing the most important results from different regions of the world, largely from Asia, Europe and North America. The results may be as disparate as the development of new materials and active composite systems, derived using theoretical predictions to complex structural systems, which generate new capabilities by incorporating enabling new smart material transducers. The theoretical predictions are usually accompanied with experimental verification, characterizing the performance of new structures and devices. These systems are examined from the nanoscale to the macroscopic. SMS has a Board of Associate Editors who are specialists in a multitude of areas, ensuring that reviews are fast, fair and performed by experts in all sub-disciplines of smart materials, systems and structures. A smart material is defined as any material that is capable of being controlled such that its response and properties change under a stimulus. A smart structure or system is capable of reacting to stimuli or the environment in a prescribed manner. SMS is committed to understanding, expanding and dissemination of knowledge in this subject matter.
