Novel sun-shading device used for automobile

Abstract

The invention discloses a novel sun-shading device used for an automobile. The device structurally comprises a winding and unwinding port, a winding drum, a protective board, a sun-shading curtain anda spring ring. The winding and unwinding port is formed in the winding drum, the winding drum and the winding and unwinding port are of an integrated structure, and the winding and unwinding port isof a rectangular structure. By the adoption of the novel sun-shading device used for the automobile, the design that the sun-shading curtain with the spring ring is arranged in the winding drum is adopted by the sun-shading device, a gear quadruple-rate rotation mechanism adopts gear type one-to-three design, a main shaft turns four circles if a rotary disc turns a circle, the winding and unwinding speed of the sun-shading curtain is then increased, more labor is saved in the use process, use is convenient and quick, the sun-shading curtain can be automatically wound and unwound, the situationthat force is applied improperly in the manual winding and unwinding process can be avoided, the sun-shading curtain can be prevented from being damaged when the space of the sun-shading curtain is compressed, and through arrangement of a press trigger mechanism, a pulley block, a worm wheel and worm rotation mechanism and a lead screw lifting mechanism, the sun-shading curtain is more stable inthe automobile sun-shading process.

Description

technical field [0001] The invention is a novel sunshade device for automobiles, which belongs to the technical field of automobile sunshade devices. Background technique [0002] During the driving process of the car, the sun will shine on the driver's eyes, which will easily cause the driver to be dazzled and emotionally fluctuate, which will affect driving safety. Therefore, a sun visor is installed in the car to block the sun. [0003] However, due to the imperfect technology of the existing technology, the sunshade cannot be opened quickly. At the same time, it needs to be manually rolled back and folded when storing. If the roll is too strong, it is easy to damage the sunshade curtain, the operation is cumbersome, and it is inconvenient to use. Contents of the invention [0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a new type of sunshade device for automobiles to solve the problem that the existing...

Problems solved by technology

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a new type of sunshade device for automobiles to solve the problem that the existing technology cannot quickly open the sunshade due to imperfect technology, and at the same time, it needs to be manually rewound and folded when storing. If the rewinding force is too small, the rewinding of the sunshade will be relatively fluffy, which will take up a lot of space. If the rewinding force is too large, it will easily damage the sunshade, cumbersome operation, and inconvenient use.
