Description

Durable take-up reel

Technical Field

The utility model belongs to the technical field of the take-up reel device and specifically relates to a durable take-up reel.

Background

When the automobile lifting glass uses the color-changing film, voltage is applied to electrodes at two ends of the electrochromic element, ions migrate into (or migrate out of) the electrochromic layer under the action of an electric field of the applied voltage, so that the valence of the electrochromic material is reduced (or increased), and before balance is achieved, the photochemical performance of the electrochromic material is changed (such as transmittance, reflectivity, absorptivity and the like) to cause the color to be changed; when equilibrium is reached, the color change of the electrochromic material is stabilized. Therefore, the glass sheet is connected with the electrode, the electrode lead passes through the winding roll and goes up and down along with the glass window, and the frequent lifting of the glass window has higher requirement on the strength of the spring contact conducting strip of the winding roll.
