Provided are power failure prevention car window roller shutter drive equipment and a use method thereof. The power failure prevention car window roller shutter drive equipment comprises a fixed frame component (8) fixed to a car body (88), and a roller shutter assembly (9) which can pivot relative to the fixed frame component (8). The roller shutter assembly (9) comprises a roller shutter rolling shaft (81), drive shaft type gears (91) and a partially-pressed pivoting wheel (94), wherein the roller shutter rolling shaft (81) is used for being fixedly connected with the upper end of a roller shutter (92) and can roll the roller shutter (92); the drive shaft type gears (91) are arranged on the front side and the rear side of the roller shutter rolling shaft (81) symmetrically and coaxially; the partially-pressed pivoting wheel (94) is fixedly connected with the lower end of the roller shutter through a flexible dragging cable; and the partially-pressed pivoting wheel (94) is partially pressed by a pivoting partially-pressing spring so that the roller shutter (92) can be tensioned downwards. Two rack drive assemblies positioned on the front side and the rear side of the roller shutter rolling shaft (81) symmetrically are arranged in the fixed frame component (8).

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 an automotive roller blind lifting device and a using method thereof, wherein the device comprises a fixing frame component (8) fixed on a vehicle body (88) and a roller blind component (9) capable of being pivoted relatively to the fixing frame component (8), the roller blind component (9) comprises a roller blind scroll (81) fixedly connected with the upper end of a roller blind (92) and capable of scrolling the roller blind (92), driving shaft type gears (91) symmetrically and coaxially arranged at the front side and rear side of the roller blind scroll (81) and a bias voltage pivoting wheel (94) fixedly connected with the lower end of the roller blind by a flexible pulling cable, and the bias voltage pivoting wheel (94) is biased by a pivoting bias spring, so that the roller blind (92) is tightly tightened downward; and the fixing frame component (8) is internally provided with two gear driving components symmetrically located at the front side and rear side of the roller blind scroll (81).

Disclosed is an intelligent animal-drawn power generating apparatus, comprising a driving wheel (1) connected to a generator (3) via a drive mechanism (2). The driving wheel is connected to an animal-power connecting rod (4), the animal-power connecting rod being radially arranged on an edge of the driving wheel. The animal-power connecting rod is used to connect to a domesticated animal and a magnetic separating device (5) is arranged at an end thereof. The end of the connecting rod is fixed to the body of the domesticated animal by means of the magnetic separating device. The magnetic separating device is connected to a controller (6), with the controller receiving an external unlocking control signal to control the separation of the magnetic separating device, such that the end of the animal-power connecting rod is separated from the domesticated animal. The power generating apparatus solves the technical problems existing in the process of animal-drawn power generation such as unstable power generation, difficulty in controlling the livestock, and the need for human supervision and management, and has better stability and the ability to control the livestock.
