Description

Automobile skylight device for protection

Technical Field

The invention relates to the field of automobile accessories, in particular to an automobile skylight device for protection.

Background

The automobile skylight is arranged on the roof of an automobile, so that air in the automobile can be effectively circulated, the entering of fresh air is increased, and healthy and comfortable enjoyment is brought to an automobile owner; the automobile skylight changes the traditional ventilation mode, wind blows in to form a stream of air flow, turbid air in a compartment is pumped out, when an automobile runs at high speed, the air flows around the automobile rapidly, when a skylight is opened, a negative pressure area is formed outside the automobile, and due to the difference of air pressure inside and outside the automobile, the turbid air in the automobile can be pumped out, so that the ventilation purpose is achieved, and fresh air is kept in the compartment all the time; and the automobile can also play a role in quickly cooling and saving energy in hot weather.

The automobile skylight can also widen the visual field, can be close to the nature and the sunshine for bathing, and can remove the oppressive feeling in the carriage; in addition, the automobile skylight is wide in view field and is often used for shooting requirements of mobile shooting and shooting, particularly, in shooting at wedding ceremonies, a camera operator shoots a wedding motorcade from the skylight, but the shooting from the skylight when the automobile stands on a seat has certain dangers, and once the automobile needs emergency braking in an emergency situation, the camera operator is easily damaged by collision and danger is generated because no protective device is arranged on the automobile skylight.

In order to solve the above problems, a chinese patent granted under publication No. CN105459766B discloses a sunroof safety device for an automobile, wherein protective devices are respectively disposed around the sunroof, a first motor rotates a first rotating shaft to pull a connecting rod to push out a baffle with a soft layer, and a rotating shaft device erects the baffle with the soft layer, so that an automobile may be protected from being hit by a car body when the automobile is subjected to sudden braking.

However, the protection device can be started only through the first motor, which undoubtedly requires manual starting of the first motor switch, but when the automobile encounters an emergency, a person may be confused and not start the first motor switch in time, so that a photographer is also injured by the automobile body.
