Sun-shading curtain and using method thereof

Abstract

The invention provides a sun-shading curtain and a using method thereof. A manual control structure for supplementing arrangement for an electric control structure is arranged, on the premise of not affecting daily electric control, a manual control mode can be switched when electric control fails, so that product improvement and promotion both having the electric control mode and the manual control mode are realized, the requirement can be met furthest, and the using comfort is improved. The sun-shading curtain comprises a hollow coiling barrel and cord fabric winding the periphery of the coiling barrel; a motor is arranged in the coiling barrel, the motor drives and is connected with a long shaft, and the motor and the long shaft separately penetrate through a plurality of limiting devices fixedly connected with the coiling barrel; a fixed device is arranged at the position, away from the side end of the motor, of the long shaft, and the fixed device is fixedly connected with the coiling barrel; a clutch device is connected between the long shaft side end and the fixed device away from the motor; the clutch device is connected with an external traction device after penetrating through the fixed device; and an elastic device is connected between one of the limiting devices and the long shaft.

Description

technical field [0001] The invention relates to a sunshade with both electric and manual control and a using method thereof, belonging to the fields of mechanical design and electric control. Background technique [0002] In order to block the glare of sunlight and avoid the abnormal temperature rise caused by sunlight, sunshade curtains are usually installed indoors or at the windows of storage devices. For example, it is applied to the windows of the cabs and compartments of rail transit vehicles, providing sunshade curtains for drivers and passengers to improve driving and riding comfort. [0003] The sunshades of existing rail vehicles have a single design structure, basically all of which are electric control structures and methods, so there are obvious limitations in use. When the electrical components are damaged or the power line is cut off, the sunshade cannot be operated, and there is no immediate remedy or alternative means, thereby reducing the riding comfort. ...

AI Technical Summary

Problems solved by technology

[0003] The sunshade of the existing rail vehicles has a relatively simple design structure, basically all of which are electric control structures and methods, so there are obvious limitations in use

When the electrical components are damaged or the power line is cut off, the sunshade cannot be operated, and there is no immediate remedy or alternative means, thereby reducing the ride comfort

[0004] There used to be a more extreme situation, that is, in the hot summer, when the rail vehicle broke down and the whole vehicle was short of power, the temperature inside the compartment rose too fast due to the failure of the control of the sunshade curtain and the direct sunlight into the compartment, which aggravated the passenger's occurrence of dehydration
