The invention relates to a driving device for a vehicle window roller blind and a using method thereof. The driving device comprises a fixed frame part (8) and a roller blind component (9), wherein the fixed frame part (8) is fixed on a vehicle body (88); and the roller blind component (9) can pivot relative to the fixed frame part (8). The roller blind component (9) comprises a roller blind scroll (81), driving shaft type gears (91) and a biasing pivot wheel (94), wherein the roller blind scroll (81) is fixedly connected with the upper end of the roller blind (92) and can wind the roller blind (92); the driving shaft type gears (91) are symmetrically and coaxially arranged on the front and rear sides of the roller blind scroll (81); the biasing pivot wheel (94) is fixedly connected with the lower end of the roller blind through a flexible traction cable; the biasing pivot wheel (94) is biased through a pivoting biasing spring so as to tension the roller blind (92) downwards; and two rack driving components, which are symmetrically positioned on the front and rear sides of the roller blind scroll (81), are arranged in the fixed frame part (8).

The invention discloses a novel single-line vertical loop device. Comprising a base and a loop body arranged on the base, and further comprises an air cylinder hinged to one side of the loop body through a support; the middle end of the swing arm is assembled and connected to the loop body through a swing shaft, one end of the swing arm is connected and assembled with the loop rising roller, and the other end of the swing arm is connected with the free end of the air cylinder. The swing arm mechanism adopts a seesaw type structure, namely a swing shaft is arranged in the middle, one end of the swing shaft is connected with a loop rising roller, and the other end of the swing shaft is connected with an air cylinder. In the working process, the hydraulic cylinder stretches out, the swing arm rotates around the middle shaft, under the same air pressure, the loop lifting force is larger, the effect is better, the stress direction of the swing arm can be adjusted at the same time by being matched with the installation height of the air cylinder, and therefore the optimal loop lifting effect is achieved.

The invention discloses an LNG high-pressure pump. The LNG high-pressure pump comprises a hydraulic cavity, a first vacuum cavity and a second vacuum cavity; a first guide ring is installed in the hydraulic cavity; a second guide ring is installed in the first vacuum cavity; a third guide ring is installed in the second vacuum cavity; the left side of the first guide ring is connected with the right side of the second guide ring through a first pump shaft; the left side of the second guide ring is connected with the right side of the third guide ring through a second pump shaft; a first hydraulic inlet and outlet and a second hydraulic inlet and outlet are respectively installed on left and right hydraulic cavities of the first guide ring; a high-pressure pipe is mounted on the second vacuum cavity on the left side of the third guide ring; and the high-pressure pipe is connected with an outlet of an LNG high-pressure pipe of a wrapped automobile exhaust collecting device, and an inletof the LNG high-pressure pipe is connected with an engine. The LNG high-pressure pump provided by the invention is a two-stage vacuum high-pressure pump; a first movable pump shaft is driven to directly move through the first hydraulic inlet and outlet, then vacuum pump bodies of the first vacuum cavity and the second vacuum cavity are driven to generate pressure, LNG is sucked through the high-pressure pipe by means of the pressure, and the LNG high-pressure pump has the advantages of being not prone to leakage and stable in transmission.
