Description

Double-end coil spring driving shaft lever Technical Field The utility model relates to the technical field of recovery systems of automobile sun shades, in particular to a double-end coil spring driving shaft lever. Background The sunshade curtain is widely applied to automobiles, although curtain recovery systems of various families are not the same, the problem of fold and relaxation in the sunshade curtain recovery process is still not completely broken through, the main power source for recovering the sunshade curtain in the prior art is from two aspects, namely, firstly, the rewinding force provided by metal shrapnel on two sides of the curtain drives the curtain to rewind in the curtain recovery process, secondly, two sides of the curtain are supported by plastic shrapnels, and the tail end of the curtain is provided with a power driving shaft lever to realize the purpose of rewinding the curtain. The existing power drive shaft lever structure is assembled by adopting a spring, a hose, an aluminum pipe, a fixer and a shaft sleeve, and then the spring is rotated and then is installed to a sunshade assembly to realize recovery of curtain cloth, but the existing power drive shaft lever structure is rotated by single-end stress of the shaft lever (namely, one spring is embedded into the shaft lever, one end of the existing power drive shaft lever structure is fixed to the inner side of the shaft lever in a riveting interference mode, the other end of the existing power drive shaft lever structure is connected with the shaft sleeve to be flush with the end of the shaft lever assembly, axial rotation force is applied through the outside, so that the spring deforms in the shaft lever to generate rollback force to drive the whole shaft lever to rotate), and the problem that wrinkles and inconsistent system load force in the rollback process of the curtain cloth are caused by uneven stress at the left end and the right ends of the curtain cloth rollback process. Based on the prior design, inspired us research on a shaft lever capable of realizing double-end power driving is that the double-end power driving is hoped to be realized in the shaft lever, so that the problems that curtain fabric folds, abnormal motor noise, long-time shaft lever unloading force cannot be recovered and the like caused by inconsistent stress in the recovery process of the sunshade curtain assembly are avoided.
