Description

Double-end-driven curved sunshade curtain recycling shaft rod structure Technical Field The utility model belongs to the technical field of automobile parts, and particularly relates to a double-end-driven curved sunshade curtain recycling shaft rod structure. Background The sun-shading curtain is widely applied to automobiles, and although curtain cloth recovery systems of all families are not the same, the problem of wrinkling and loosening in the sun-shading curtain recovery process is still not completely broken through, and along with the development of the automobile industry, the requirements of consumers on head space are also higher and higher. The main power source for recovering the sunshade curtain cloth in the prior art is from two aspects, namely, firstly, the rolling force provided by the metal elastic sheets on two sides of the curtain cloth drives the curtain cloth to roll back in the process of recovering the curtain cloth, secondly, the two sides of the curtain cloth are supported by the plastic elastic sheets, and the tail end of the curtain cloth is provided with a power driving shaft lever to achieve the aim of rolling the curtain cloth back. Because the material and processing cost of the metal spring plate are far higher than those of the plastic spring plate, the mode is gradually replaced by a plastic spring plate powered driving shaft recovery system, and because the tail end power driving shaft rod is mostly in a straight shaft form, the head space of an occupant in the vehicle can be occupied. The existing power driving shaft lever structure is assembled by adopting a spring, a hose, an aluminum pipe, a fixer and a shaft sleeve, and the curtain cloth is recovered by rotating the spring and mounting the spring to a sunshade curtain assembly. But present power drive axostylus axostyle structure is single-ended atress rotation of axostylus axostyle (a spring embedding is advanced inside the axostylus axostyle promptly, and one end is fixed to the axostylus axostyle inboard through the riveting interference mode, and other end connecting axle sleeve and axostylus axostyle assembly tip parallel and level, through outside applied axial rotation force, makes the spring take place to deform in the axostylus axostyle and produces the recoil force and drive whole axostylus axostyle and carry out the rotation), has the curtain cloth to roll up in-process both ends atress inequality about leading to curtain cloth rollback the in-process fold and the inconsistent problem that leads to the motor abnormal sound of system load force. There is a need in the art for a new solution to this problem. Disclosure of utility model The utility model aims to solve the technical problem of providing a double-end-driven curved sunshade curtain recovery shaft rod structure which is used for solving the problems of uneven curtain cloth rewinding stress, abnormal motor noise and occupied head space in a vehicle in the prior art. The technical scheme adopted by the utility model is to provide a double-end-driven curved sunshade curtain recovery shaft rod structure, which comprises a curved iron pipe, wherein a double-end spring driving assembly is arranged outside the curved iron pipe and comprises a double-end spring positioner sleeved on the curved iron pipe, the double-end spring positioner is fixedly connected on the curved iron pipe, two ends of the double-end spring positioner are symmetrically connected with two springs through threads, the springs are sleeved outside the curved iron pipe, a hose is sleeved outside the springs, the other ends of the springs are respectively connected with a spring shaft, and shaft sleeves are connected to the spring shafts in a penetrating manner and are used for realizing assembly sealing; and a plastic corrugated pipe is sleeved outside the double-end spring driving assembly. The curved iron pipe is made of 304 stainless steel. The plastic corrugated pipe is made of PA6 material. The double-end spring positioner is fixedly connected with the curved iron pipe in a riveting mode. The screwing torque of the spring is not constrained, and is constrained by the size, the material and the number of convolutions. Through the design scheme, the utility model has the following beneficial effects: 1. and the double-side balanced driving is that double springs are symmetrically distributed, so that the problem of single-side stress concentration is solved, and the curtain fabric wrinkling rate is reduced. 2. Space optimization, namely, an arc-shaped main body structure of the bent iron pipe avoiding head space improves the utilization rate of vertical space in the vehicle. 3. And the material adaptation is that the plastic corrugated pipe is matched with the curved iron pipe, so that the rotating deformation requirement of the curved iron pipe is adapted, and the force unloading risk in long-term use is reduced. 4. The structure is stable, the shaft sleeves at the two ends are u
