Description

Description Vehicle-Mounted Automatic Umbrella Technical Field The invention relates to an automatic umbrella, more particularly to a vehicle-mounted automatic umbrella, which is also called as movable shed. Background Temperature reduction or shading is needed when a vehicle travels or is parked in the hot sun; in fact, the problem of temperature reduction is not serious because air conditioner is on when a vehicle travels; but once the vehicle is parked, air conditioner is seldom on owing to its massive energy consumption, thus, people will usually feel unbearable when returning to a vehicle that is parked in summer in southern areas like Guangdong. When a vehicle is parked under trees, it is necessary to prevent birds' droppings and other junks from falling onto vehicle roof; and it is also necessary to prevent snow accumulation on vehicle roof when a vehicle is parked on a snowy day in bitter winter. At present, there are a variety of tools for the sunscreen of vehicles in summer. However, the vehicle-mounted automatic umbrella, which has been contained in the roof of vehicle body completely to be integrated with vehicle without changing the current vehicle structure and can solve many of the above problems, has not been developed. The vehicle-mounted automatic umbrella of the invention that is popped out of vehicle body when in use has the functions of sunscreen, ventilation and temperature reduction in hot weather in summer and can prevent snow accumulation to a certain extent in snowy weather in winter so that removal of the accumulated snow before driving is facilitated.

Snow accumulation can be prevented to a certain extent in snowy weather in winter so that removal of the accumulated snow before driving is facilitated. Besides, the folding and unfolding of this umbrella can be remotely controlled as required. After the vehicle-mounted automatic umbrella is unfolded, a particular space is formed between the umbrella vanes and vehicle roof to realize air ventilation, in this case, a vehicle is parked just as under a tree or in a garage; the umbrella vanes could cover the entire vehicle roof without exceeding the maximal external dimension of vehicle body, therefore, the umbrella is not only wide in shading area, but also has no negative impact 3 on adjacent vehicles no matter they are traveling or parked. The containing cavity of the vehicle-mounted automatic is disposed centrally inside vehicle roof, and in general, this part only needs to be thickened by a few centimeters along the direction towards interior trim part. Consumers are amenable to the design that the umbrella box cover is a part of vehicle roof outer shell because such a design will not affect the original appearance of vehicle body; in addition, since the umbrella is folded inside vehicle, the umbrella can also be prevented from damage or theft. When a vehicle is parked in summer, this product can be used for shading the sunlight in order to prevent rapid temperature rise that is caused by direct illumination of the sunlight on vehicle roof and save energy consumption for temperature reduction, so this product is favorable for environmental protection to a certain extent. To conclude, the invention has the advantages of small size, wide shading area, convenient use, attractive appearance, no addition of wind resistance, reduction of energy consumption for reducing temperature and environmental protection.
