Background

Along with the continuous improvement of living standard of people, people have higher and higher requirements on the comfort level of living environment, and the sun shading and heat insulation are an important part of the living environment. Meanwhile, along with the improvement of the quality requirement of the existing sunshade products, people pay more and more attention to the durability and convenience of the sunshade products, such as common fabric sunshades, honeycomb blinds and the like. Because the solar cell does not have a heat insulation function, the solar cell has poor sun-shading effect and weak oxidation resistance and corrosion resistance, and is easy to fade and weather, thereby affecting the beauty.

The aluminum alloy external sunshade roller blind is applied to various building decorations according to different requirements, such as villas, office and business buildings, sunlight rooms, hotels, high-end factory buildings and the like.

Disclosure of Invention

The invention aims to design a nonlinear adjusting device of an external sunshade roller shutter. 1. The problem of when the outer sunshade roller shutter product of aluminum alloy was installed at the level, when the aluminum alloy sunshade roller shutter blade was expanded, under the traction force condition, the aluminum alloy roller shutter blade had the draw-in groove phenomenon because the guide rail groove resistance in both sides is inequality is solved. 2. The defects that an elastic energy storage device is short in service life and only can be installed on one side and stressed unevenly in actual use of an existing torsion spring adjusting device are overcome. 3. The problem of speed and the unmatched traction wire rope winding speed when rolling up the curtain blade when coiling is solved.

The non-linear adjusting device of the external sunshade roller blind is designed for the purpose. The outer sunshade roller blind is provided with two symmetrical non-linear adjusting devices, and traction force is provided by utilizing the elastic potential energy of a metal spring of the non-linear adjusting devices. The soft steel wire ropes are used as traction at the two ends of the bottom edge of the aluminum alloy outer sunshade roller shutter, so that the problem of clamping grooves is well solved. The soft steel wire rope bypasses the pulley at the bottom end of the sliding groove of the frame, and the other end of the soft steel wire rope is connected with a groove disc of the nonlinear adjusting device of the outer sunshade roller shutter. Because the rotating speed of the motor is constant, the outer sunshade rolling curtain nonlinear adjusting device is sleeved on the scroll, the rotating speed of the outer sunshade rolling curtain is the same as the rotating speed of the motor, the motor drives the scroll to rotate, the linear speed of the outer sunshade rolling curtain blade is changed from high to low, and when the unfolding speed of the outer sunshade rolling curtain blade is lower than the winding speed of a steel wire rope on the nonlinear adjusting device. The elastic potential energy of the spring is increased through the nonlinear adjusting device, so that the difference between the theoretical length of the steel wire rope coiled by the nonlinear adjusting device and the actual length of the steel wire rope coiled by the nonlinear adjusting device is absorbed. The unfolding operation of the aluminum alloy outer sunshade roller shutter is realized.

When the motor drives the scroll to roll the aluminum alloy roller shutter, the rotational speed of the scroll and the outer sun-shading roller shutter nonlinear adjusting device is the same and constant. And the rolling speed of the aluminum alloy outer sunshade roller shutter blade is changed from slow to fast. When the rolling speed of the rolling shutter blade is greater than the releasing speed of the steel wire rope on the nonlinear adjusting device. At the moment, the nonlinear adjusting device of the outer sunshade roller shutter compensates the requirement on the length of the flexible steel wire rope when the outer sunshade roller shutter blade is wound in a nonlinear mode by releasing the elastic potential energy of the spring.

The invention has the beneficial effects that:

the invention has reasonable design and compact structure, can effectively solve the problem of a clamping groove which is possibly generated in the horizontal installation and use process of the external sunshade roller shutter, and simultaneously eliminates the influence of unmatched winding speed of a steel wire rope and the nonlinear winding speed of blades of the external sunshade roller shutter. Meanwhile, the nonlinear adjusting device adopting the metal spring structure has the advantages that the elastic potential energy adjusting space is large, two sides can be simultaneously installed, the stress is uniform, and the defects that the elastic energy storage device is short in service life, uneven in single-side installation stress and the like in the actual use of the original torsion spring adjusting device are overcome. The device has the characteristics of simple structure, attractive appearance, reasonable layout, convenience in field construction and installation, low cost and the like, and is suitable for popularization and application.
