Abstract: The present invention discloses a car cover limiting structure, it includes a guide rail, a side rail and a first side rail limit positioning block, the first side rail limit positioning block is connected to the side rail, the first side rail limit positioning block includes a barrier plate, the barrier plate is used to resist and limit with the guide rail. By setting the car cover limiting structure, the present invention enables the car cover does not to move from side to side in use, so as to facilitate the opening and closing of the car cover.

Abstract: The present invention discloses a car cover with rotating shaft hinges, including a large front bar, a rear bar, a guide rail and a plurality of rotating shafts, the guide rail is connected to the car body, the large front bar, the rear bar and the plurality of rotating shafts are all connected to the guide rail, at least one of the rotating shafts is connected to a rotating shaft hinge, the rotating shaft includes a first rotating shaft, a second rotating shaft and a third rotating shaft. The car cover in this invention may includes a plurality of rotating shaft structures or only one rotating shaft structure, the rotating shafts are connected at the rotating shaft by a rotating shaft hinge, which makes the rotating shaft a longer service life.

Abstract: A lithium-ion battery and a method of preparing the same are provided. The lithium-ion battery includes a cell and an electrolyte solution, and the cell includes a negative electrode sheet. The negative electrode sheet includes a negative electrode current collector, an active coating layer disposed on a surface of the current collector, and a protective coating layer disposed on a surface of the active coating layer. The protective coating layer is a solid-state electrolyte coating layer. The electrolyte solution contains a film-forming agent. The method includes the following steps. After the cell is placed in a casing and the electrolyte solution is injected, formation is performed on the lithium-ion battery. The formation includes: S1, performing charging to 3.4V to 3.75V with a constant current rate of 0.02C to 0.04C; and S2, performing charging to 3.75V to 4.25V with a constant current rate of 0.05C to 0.3C.
