技术领域 technical field

本发明属于发电装置技术领域，涉及一种汽车减震器发电装置。The invention belongs to the technical field of power generation devices, and relates to a power generation device for automobile shock absorbers.

背景技术 Background technique

永磁直线式发电是一种用于特种直线发电机的技术，相比于传统的旋转式发电，用永磁体代替了电励磁，使发电结构更为简单，电气控制更为简便。永磁体直线发电机体积小、质量轻、损耗少、效率高，在微型电机领域有很好的应用前景。尤其对于动力源为振荡运动形式的场合，由于省去了运动转化装置，可将机械能直接变为电能，发电效率变的更高。本发明所采的减震器发电结构即采用永磁体直线发电的形式。Permanent magnet linear power generation is a technology for special linear generators. Compared with traditional rotary power generation, permanent magnets are used instead of electric excitation, which makes the power generation structure simpler and electrical control easier. Permanent magnet linear generators are small in size, light in weight, low in loss and high in efficiency, and have good application prospects in the field of micro motors. Especially for occasions where the power source is in the form of oscillating motion, since the motion conversion device is omitted, the mechanical energy can be directly converted into electrical energy, and the power generation efficiency becomes higher. The shock absorber power generation structure adopted in the present invention adopts the form of permanent magnet linear power generation.

近年来,中国汽车产量与保有量逐年上升，汽车对原油的消耗和对环境的破坏都极其巨大。然而，汽车对能源的利用效率很低,要想实现节能减排、保护环境的目的，提高汽车对能源的利用效率是极为切实有效的办法。现有的汽车悬挂系统中的减震器，其往复运动的机械能最终会转化成无用的内能并对减震器造成一定的损耗，着实是对能源和材料的一种浪费。In recent years, China's automobile production and ownership have increased year by year, and the consumption of crude oil and the damage to the environment by automobiles are extremely huge. However, the energy utilization efficiency of automobiles is very low. To achieve the purpose of energy saving, emission reduction and environmental protection, improving the energy utilization efficiency of automobiles is a very practical and effective way. For the shock absorber in the existing automobile suspension system, the mechanical energy of its reciprocating motion will eventually be converted into useless internal energy and cause a certain loss to the shock absorber, which is really a waste of energy and materials.

虽然直线发电技术在磁悬浮列车、斯特灵发电机上已经得到了广泛的应用，但在汽车减震器上目前未见使用。这是因为减震器的尺寸较小，现有的直线发电设备难以满足直接安装的要求，同时由于减震器的振荡具有很大的随机性，通过发电结构回收产生的电能波动较大、电压变化剧烈、脉冲信号较多。如果将此回收的电能直接输出，将给蓄电池带来很大的冲击，影响各元件的寿命。因此必须开发具有新型发电结构和调整电路的汽车减震器发电装置。Although linear power generation technology has been widely used in maglev trains and Stirling generators, it has not been used in automobile shock absorbers. This is because the size of the shock absorber is small, and the existing linear power generation equipment is difficult to meet the requirements of direct installation. At the same time, because the vibration of the shock absorber has great randomness, the electric energy recovered through the power generation structure fluctuates greatly, and the voltage There are drastic changes and many pulse signals. If the recovered electric energy is directly output, it will bring a great impact to the battery and affect the life of each component. Therefore, it is necessary to develop an automobile shock absorber power generation device with a new power generation structure and an adjustment circuit.
