Description
Technical Field
The invention relates to an automobile kinetic energy power generation system and method, in particular to a resonance power generation distributed architecture of a single series-connection hydraulic vibration loop.
Background
As is known, the automobile shock absorber dissipates most energy of the vibration of the automobile body by throttling damping work and friction heat dissipation, and the existing automobile vibration power generation technology is developed and utilized aiming at the residual vibration energy of the automobile body after being dissipated by the shock absorber, namely, a low-power generator is added on the shock absorber, the random vibration force generated after the vibration of the shock absorber of the automobile body is utilized to drive and generate power, and the defects of the random vibration power generation are obvious, and mainly: 1) because most of the vibration energy of the vehicle body is shunted and dissipated by the throttling damping work of the vibration absorber, the residual vibration force for driving the low-power generator is very low, and the amplitude of the vehicle body is very small, so that the torque and the rotating speed of key elements influencing the generating efficiency of the generator are very low, the efficiency of the low-power generator dispersedly arranged on each vibration absorber of the vehicle body is very low, the overall recovery efficiency of the residual vibration energy of the vehicle body is very low, and the application prospect is lacked; 2) meanwhile, the electromagnetic damping generated by utilizing the vibration energy for power generation is very small, and the effective vibration suppression of the vehicle body can not be carried out only by utilizing the electromagnetic damping, so that the conventional vibration energy random vibration power generation technology can not effectively replace the conventional vibration absorber, the energy recovery power generation effect is poor, and the vibration suppression balance of the vehicle body is also very poor.
The applicant is continuously researching and improving the leading-edge technical research of realizing the body vibration energy recovery power generation of the new energy automobile by utilizing the frequency resonance from 2010, and hopefully perfectly applying the technology which is favorable for greatly improving the vibration energy utilization efficiency in the automobile industry, thereby saving energy and really realizing the floor application of the subversive energy regeneration technology.
A frequency resonance implementation method applied to the kinetic energy power generation of an electric automobile is proposed from 2012 (patent number: CN201210114577.6), and a method and a structure for applying frequency resonance to the kinetic energy power generation of the automobile are further proposed from 2013 (patent number: CN201310132727.0), and a first generation resonance power generation device and system are developed on the basis. However, in view of the need for controlling the vibration of the vehicle body, not only the vibration energy needs to be utilized efficiently, but also the influence of the vibration on the vehicle body bumping needs to be controlled, the applicant in 2016 has proposed a lever principle-based method and structure for optimizing the resonance power generation of the electric vehicle (patent No. CN201610496171.7), and developed a second generation resonance power generation device and system.
However, the actual installation and compatibility of the rigid lever for the vehicle are poor, and the rigid lever cannot control the magnitude of the vibration force, so a third generation lever effect-based electric vehicle resonance power generation hydraulic driving method and device are proposed in 2018, and the hydraulic device is utilized to realize the lever effect and improve the compatibility and control of the magnitude of the vibration force.
However, the second generation lever driving method and the third generation hydraulic driving method have certain effects in suppressing vibration of the vehicle body and performing resonance power generation by using vibration force, but since both of these structures and methods are based on single-group three-drive three-rigid lever unit driving and single-group three-drive three-hydraulic unit driving, they are limited in compatibility with a chassis area thrust rod, a stabilizer bar, and a substitute damper, it is difficult to provide a plurality of groups of vibration conduction units for each axle as a support, and there are still deficiencies in balance of vibration suppression of the vehicle body and high efficiency of vibration power generation.
