The application relates to the field of automotive supplies, in particular to an automotive sunshade with a manually retractable device.
Nowadays, the vehicle ownership in China has grown very rapidly. Due to the scarcity of urban space, it is hard to build enough garages to park vehicles, for which many people have to park their vehicles on the roadside and outdoors. Every time in summer, the scorching sun continuously shines on the vehicles parked outdoors. Due to the high heat storage capacity of the metal housing of the vehicles, each vehicle is like an oven after a long period of exposure to the sun, which also intensifies the urban heat island effect.
The continuous heat increases the temperature inside the vehicle, even reaching above 60° C. Under such temperature, vehicle interior materials will continue to volatilize harmful substances, which will still be inhaled into the human body even after opening the door for ventilation, causing damage to human health.
In addition, the continuous exposure to the sun will cause serious aging of the internal and external materials of the vehicle, which not only increases the waste caused by replacing parts, but more seriously may cause the internal circuit of the vehicle to catch fire, causing the vehicle to spontaneously ignite and cause major accidents. Therefore, how to keep the vehicles parked outdoors from being exposed to the sun has become an urgent problem to be solved.
Aiming at the above problems, the prior art provides some solutions, such as setting a windshield sunshade device that can be stretched on the roof of the vehicle.
