技术领域technical field

本实用新型涉及运动发电技术领域，特别涉及一种可穿戴式运动发电技术。The utility model relates to the technical field of sports power generation, in particular to a wearable sports power generation technology.

背景技术Background technique

随着信息技术和微电子技术的发展，电子智能设备已经融入了我们的生活，但这些设备的续航能力始终有限，为了确保设备电量的充足，人们出门携带充满电量的移动电源已成常态。而人们在出行、运动时，无时无刻不在输出机械能，如果能将这部分能量通过一种可穿戴式的微型发电装置转化为电能储存起来，既能节省给移动电源充电的电能，又能解决人们急需给电子设备充电的燃眉之急。With the development of information technology and microelectronics technology, electronic smart devices have been integrated into our lives, but the battery life of these devices is always limited. In order to ensure sufficient power for devices, it has become normal for people to carry mobile power banks with full power when they go out. When people are traveling and exercising, they output mechanical energy all the time. If this part of energy can be converted into electrical energy and stored through a wearable micro-generating device, it can not only save the electrical energy for charging the mobile power supply, but also solve people's urgent needs. An urgent need to charge electronic devices.

收集人体机械能的装置主要可以分为压电式、电磁式、静电式3类。静电式振动发电装置需要外加电源对其进行初始充电，限制了其应用范围。压电技术收集人体机械能的装置，发电效率比较低，而且不易于人体穿戴。电磁式振动发电本身实用性强，功率密度高，易于集成，适合于作为回收人体机械能的发电装置。但目前大多数电磁式振动发电装置存在体积大、发电效率低、机械磨损强的缺陷。The devices that collect the mechanical energy of the human body can be mainly divided into three categories: piezoelectric, electromagnetic, and electrostatic. The electrostatic vibration power generation device requires an external power supply for initial charging, which limits its application range. Piezoelectric technology is a device that collects the mechanical energy of the human body. The power generation efficiency is relatively low, and it is not easy for the human body to wear. Electromagnetic vibration power generation itself has strong practicability, high power density, and is easy to integrate. It is suitable as a power generation device for recovering human mechanical energy. However, most of the current electromagnetic vibration power generation devices have the defects of large volume, low power generation efficiency, and strong mechanical wear.

例如：据检索，目前已有将振动发电能量采集的装置，如公开号为CN104935147A的中国专利申请公开了一种梯形磁轭永磁振动发电装置，由一圆柱形外壳、一个振动轴、四个梯形磁轭、四个线圈、一个弹簧装置所组成。振动轴置于中心且伸出顶盖，四个梯形磁轭固定在圆柱的中心对称分布，线圈缠绕在梯形磁轭当中，弹簧置于外壳底端与振动轴接触，利用振动轴的上下振动发电。For example: according to the search, there are currently existing devices for collecting vibration power generation energy, such as a Chinese patent application with a publication number of CN104935147A disclosing a trapezoidal yoke permanent magnet vibration power generation device, which consists of a cylindrical shell, a vibration shaft, four It consists of trapezoidal yoke, four coils and a spring device. The vibration shaft is placed in the center and protrudes from the top cover. Four trapezoidal yokes are fixed on the center of the cylinder and distributed symmetrically. The coil is wound in the trapezoidal yoke, and the spring is placed at the bottom of the shell to contact the vibration shaft. The up and down vibration of the vibration shaft is used to generate electricity. .

又如公开号CN204534160U的中国专利申请公开了一种振动发电手电筒，其包括筒体、发电线圈、永磁动子、整流储能模块、导管、LED灯等。LED灯安装在筒体上端，发电线圈嵌套在导管外侧，永磁振子放在导管内，永磁振子两端连接弹簧，通过手摇振动发电进行照明。Another example is the Chinese patent application with the publication number CN204534160U disclosing a vibrating power generation flashlight, which includes a cylinder, a power generation coil, a permanent magnet mover, a rectifying energy storage module, a catheter, an LED lamp, and the like. The LED lamp is installed on the upper end of the cylinder, the power generation coil is nested outside the conduit, the permanent magnet vibrator is placed in the conduit, and the two ends of the permanent magnet vibrator are connected to springs, and the light is generated by hand vibration.

上述两种装置对于振动所发电的采集的技术方案均存在不足之处，第一种技术方案的装置振动轴延伸在外面容易使装置受到破坏，仅有下面的弹簧连接也使得它不能收集高频的振动的能量；整个装置的气隙很大漏磁较多，并且体积较大，适用性较小；装置由于没有储能部分，无法把收集到的能量储存下来。第二种装置，结构比较简单，但漏磁通比较多，磁动子的有效行程短，致使其发电效率较低。Both of the above two devices have deficiencies in the technical solutions for collecting power generated by vibration. In the first technical solution, the vibration axis of the device extends outside and it is easy to damage the device. Only the spring connection below makes it unable to collect high frequencies. vibration energy; the whole device has a large air gap and more magnetic flux leakage, and its volume is large, and its applicability is small; since the device has no energy storage part, it cannot store the collected energy. The second type of device has a relatively simple structure, but there are more leakage fluxes, and the effective stroke of the magnetic mover is short, resulting in low power generation efficiency.

该装置可放置于所述的运动臂包中。The device can be placed in said sports arm bag.

本实用新型的工作过程和原理是：Working process and principle of the present utility model are:

该装置通过臂包固定在人体上。环形永磁体钕铁硼沿铁芯轴方向主要受自身重力以及两端弹簧的弹力作用，当该装置静止时，这三个力处于平衡状态；一旦该装置随着人体运动，原来的受力平衡被打破，发电机两端的弹簧对永磁体的弹力大小发生变化，永磁体在弹力的作用下沿铁芯轴方向振动。同时，当该装置摆动时，两个发电单元在轴承中小幅度转动，使得永磁体在沿铁芯轴方向上产生尽可能大的位移。The device is fixed on the human body through an arm pack. The annular permanent magnet NdFeB is mainly affected by its own gravity and the elastic force of the springs at both ends along the axis of the iron core. When the device is stationary, these three forces are in a balanced state; once the device moves with the human body, the original force balance If it is broken, the elastic force of the springs at both ends of the generator to the permanent magnet will change, and the permanent magnet will vibrate along the direction of the iron core axis under the action of the elastic force. At the same time, when the device swings, the two generating units rotate in a small range in the bearing, so that the permanent magnet produces as large a displacement as possible along the direction of the iron core axis.

永磁体与铜质线绕制的线圈的相对位置发生变化，从而引起线圈交链磁链的改变，根据法拉第电磁感应定律，线圈中会产生交变的感应电动势，而且电动势的大小与通过线圈的磁通量随时间的变化率成正比。为了获得较大的电流，该装置将两个线圈并联。The relative position of the permanent magnet and the coil wound with copper wire changes, which causes the change of the coil interlinkage flux linkage. According to Faraday's law of electromagnetic induction, an alternating induced electromotive force will be generated in the coil, and the magnitude of the electromotive force is the same as that passing through the coil. The rate of change of magnetic flux with time is proportional. In order to obtain a larger current, the device connects two coils in parallel.

线圈两端通过整流稳压电路与电池连接，从而实现储能；电池可为照明电路提供电量，且通过升压电路对MP3、手机等电子设备供电。Both ends of the coil are connected to the battery through a rectification and voltage stabilization circuit to realize energy storage; the battery can provide power for the lighting circuit, and power electronic devices such as MP3 and mobile phones through the boost circuit.

与现有技术先相比，本实用新型的有益效果是：Compared with the prior art, the beneficial effects of the utility model are:

一、本实用新型的发电单元采用永磁体外置式的结构，线圈缠绕于环形永磁体内部，节省材料和减轻重量的同时，能有效地减少漏磁和降低去磁效应，提高发电效率和性能的稳定性，并在一定程度上延长发电单元的使用寿命。1. The power generation unit of the present utility model adopts a permanent magnet external structure, and the coil is wound inside the annular permanent magnet, which saves material and weight, and can effectively reduce magnetic flux leakage and demagnetization effect, and improve power generation efficiency and performance. Stability, and to a certain extent prolong the service life of the power generation unit.

二、本实用新型的发电单元通过转动连接轴与装置外壳连接，巧妙地让两个发电单元随着整个装置的摆动实现小幅度转动，从而带动永磁体直线振动，配合人体惯用运动方式达到更高效的发电效果。2. The power generation unit of the utility model is connected with the device shell through the rotating connection shaft, so that the two power generation units can be rotated in a small range with the swing of the whole device, so as to drive the permanent magnet to vibrate in a straight line, and cooperate with the habitual movement of the human body to achieve higher efficiency power generation effect.

三、本实用新型的发电单元通过将永磁体两端面与弹性构件连接，不仅可以消除永磁体和断面间的机械磨损，使得振动的机械能充分被利用，让永磁体得到来回振动，振动在短时间内连续不间断，从而提高了发电效率。3. By connecting the two ends of the permanent magnet with the elastic member, the power generation unit of the present utility model can not only eliminate the mechanical wear between the permanent magnet and the section, but also make full use of the mechanical energy of the vibration, so that the permanent magnet can vibrate back and forth, and the vibration can be achieved in a short time. Continuous and uninterrupted, thus improving the power generation efficiency.

这样，人在做摆臂运动时，如果将本装置安装在手臂上，发电单元与外壳的连接轴可以小幅度转动，使得磁体运动方向在手臂运动方向的分量增大，从而使得发电效率得到提高。同时，装置在振动的工程中，永磁体两端的弹簧起到了增加单位时间磁体切割磁感线次数，并且避免磁体与断面相撞的作用，提高了发电效率，减少了机械损耗。In this way, when a person is doing arm swing movement, if the device is installed on the arm, the connecting shaft between the power generation unit and the casing can rotate slightly, so that the component of the magnet movement direction in the arm movement direction increases, thereby improving the power generation efficiency. . At the same time, during the vibration project of the device, the springs at both ends of the permanent magnet can increase the number of times the magnet cuts the magnetic induction line per unit time, and avoid the collision between the magnet and the section, which improves the power generation efficiency and reduces the mechanical loss.
