This invention discloses a combined solar power generation and gravity energy storage power supply system and method. The power supply system includes a solar power generation system, a gravity energy storage system, and an intelligent control system. The intelligent control system presets a power generation threshold and dynamically controls the gravity energy storage system to store or release energy based on the difference between the real-time solar power generation and the threshold, thus stabilizing the combined output power. The gravity energy storage unit adopts a symmetrical double-sloped support tower and a dual energy storage structure design, achieving bidirectional conversion between electrical energy and gravitational potential energy through a clutch mechanism. The intelligent control unit dynamically adjusts the floating threshold based on predicted wind speed and historical power fluctuation rate, improving the system's adaptability to different wind fields. The coordinated control of power generation and energy storage solves the intermittency problem of wind power generation, reduces the amplitude of output power fluctuations, and the bidirectional energy conversion mechanism can achieve peak shaving and valley filling, releasing energy to supply power during peak electricity demand and storing energy during off-peak times, improving the overall energy efficiency of the power grid and avoiding energy waste.

The utility model relates to new energy vehicle manufacturing technical field especially relates to a front hatch structure of reducing wind resistance, including front cabin, front hatch, hinge, electric telescopic link and universal ball, wherein, hinge is located between the front end of front hatch and the front side top of front cabin, is used for rotatably connecting on the front cabin with front hatch, one end of electric telescopic link is hinged to the side portion of front cabin through a universal ball, the other end is hinged to the bottom of front hatch through another universal ball, electric telescopic link is used for driving front hatch to rotate around hinge, to adjust the opening angle of front hatch rear end relative to front cabin. Through electric telescopic link, the initiative adjustment of front hatch rear end angle is realized, can dynamically optimize the airflow transition between front hatch and front windshield during the vehicle driving process, effectively reduces the whole vehicle wind resistance, solves the problem that the existing automobile front hatch cannot adjust the front hatch angle according to the driving state.
