BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for protecting a vehicle surface, and more particularly, to protect a vehicle surface that protects the surface of the vehicle from impacts, scratches, or contamination from the outside by fixing the protective cover to the exterior surface of the vehicle with a simple operation. Relates to a device.

In general, if the cover for the car developed to protect the car is stored separately, there is a removable cover used to cover the car as needed, and a fixed cover that is fixedly attached to the front and rear bumpers of the car.

In the case of such a car cover, not only protects the exterior of the chassis of the vehicle from snow or rain, but also prevents damages such as scratches and dents on the exterior of the chassis of the automobile, and further protects the vehicle from impacts from the outside. do.

However, it is practically impossible to protect the car from moisture caused by temperature changes such as moisture or condensation caused by climatic factors caused by rainfall or snowfall, and due to moisture or moisture generated by such phenomenon, Automotive cover is inevitably exposed to moisture, etc. Due to this, the conventional automotive cover had a problem that takes a lot of effort and time when installed in the car or stored separately.

As a result of the inconvenience of using the cover for the car, it is economically burdened by leaving the car cover purchased at a relatively high price and leaving it in the trunk of the car or at home. Frequent damage from exposure to shock and scratches has occurred.

In addition, even if the cover is installed on the car to take the hassle for the protection of the car had a problem that can not properly protect the car from impact due to contact or collision with other vehicles.

Therefore, all covers, such as the trunk cover or removable storage cover or the bumper attachment type cover, do not alleviate the inconvenience of use at all, and do not properly protect the car from small impacts from the outside. There is a need for the development of protective covers for automobiles.

The present invention is to solve the above-mentioned conventional problems, the object of the present invention is to prevent the damage to the surface of the vehicle due to the impact or scratches applied from the outside by fixing the protective cover on the outer surface of the vehicle with a simple operation. It is to provide a vehicle surface protection device to protect the vehicle surface from external pollution such as moisture or dust such as rain, snow or snow.

The present invention for realizing the above object is a device for protecting the surface of the vehicle, provided with a protective cover provided on the surface of the vehicle to protect the exterior surface of the vehicle from impact or contamination, and provided on the protective cover to be detachable to the vehicle It characterized in that it comprises an attachment means to be attached.

In addition, the present invention is a device for protecting the surface of the vehicle, which is installed on the surface of the vehicle to protect the exterior surface of the vehicle from impact or contamination, the protective cover having a restoring force to maintain a flat against the rolling, and the protective cover is rolling Rolling means comprises a rolling means is fixed to the end of the protective cover and the protective cover is rolled on the outer circumferential surface, the rotation support for rotatably supporting the pulley, and the pulley to roll the protective cover or to be released from the pulley The motor for rotating the pulley in both directions so that the protective cover covers the outer surface of the vehicle by the restoring force, and the rotation support is coupled to both ends so that the pulley is rotatably installed inside, and the motor is installed on any one of the rotation support. , A slit is formed along the longitudinal direction so that the protective cover rolled on the pulley is drawn out, Lu, or it characterized in that it comprises a case which is detachably installed in an automobile.
