After the door body is opened, it is located above, does not occupy the space in front of the door and the courtyard, and is also more beautiful.

[0018] 2. By installing a sunshade and a telescopic mechanism, when it is necessary to move in the courtyard but the sunlight is relatively strong, simply turn the door body to the horizontal position and then start the first motor. The bevel gear pair, drive shaft, worm and worm gear assembly, and transmission shaft drive the threaded rod to rotate, and then the sunshade is pushed out of the storage groove through the slider. The sunshade extends into the courtyard to play a role in shading.

[0019] 3. By installing a sunshade cloth, when it is necessary to further expand the shading area, simply start the air pump, and inflate the two telescopic air bags through the air outlet pipe. The telescopic air bags are inflated and expanded, and the sunshade cloth is pulled out and unfolded through the extension rod and the connecting plate to expand the activity space. At the same time, the door body is in the open state, and the ventilation effect is good.

[0020] 4. By installing a pull rope, after the sunshade and the sunshade cloth are unfolded, the pull rope plays a role in stably supporting the sunshade and the sunshade cloth under the limit of the ratchet and pawl. A second motor is provided. When it is necessary to retract, simply start the second motor to release the limit, and the pull rope can be wound synchronously.

[0021] 5. By installing an air pump and a blow pipe, when the weather is relatively hot and sitting under the sunshade to enjoy the cool or move, the gas blown out by the air pump can enter the blow pipe through the electromagnetic three-way valve, and then be blown downward through multiple branch pipes and blow holes to achieve a cooling effect and make it more comfortable.

[0022] 6. By laying photovoltaic panels, when the door body is in the horizontal state, the sunlight directly acts on the photovoltaic panels to generate electricity, which supplies power to the internal control, saving energy and being environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
