[0014] A method for operating an intelligent building awning that can be retracted to the ground comprises the following steps: Step 1: The awning is unfolded. The building awning is folded and placed on the ground. First, the first hinge shaft is driven to drive the frame straight plate to swing upright. The frame straight plate and the ground recess frame are pulled apart to unfold the tail cloth. Then, the second hinge shaft is driven to drive the awning recess frame to swing flat. The frame straight plate and the awning recess frame are pulled apart to unfold the wall cloth on both sides. The wind measuring beam moves to pull the sunshade cloth. The sunshade cloth is stretched and laid flat on the awning recess frame. The building awning is unfolded. Step 2: Awning protection. You can choose whether to plug a wind blocker into the pressure gauge. Inserting the wind blocker can make the unfolded building awning have a protection mechanism. If there is strong wind, the airflow will cause the wind blocker to swing excessively, which will automatically trigger the protection mechanism. The sunshade cloth will be quickly rolled up, and the clamping state of the clamp connecting the tail cloth and the wall cloth will be broken. The tail cloth and the wall cloth will quickly separate. After the tail cloth is completely shrunk, it will be attached to the ground frame, and the wall cloth will be completely shrunk and attached to the awning frame. The building awning will become a wind-resistant skeleton. Step 3: The frame awning is folded up. First, the second hinge shaft is driven in the reverse direction to drive the awning recess frame to swing downward. The awning recess frame and the frame straight plate are folded together. Then, the first hinge shaft is driven in the reverse direction to drive the folded awning recess frame and the frame straight plate to swing toward the ground recess frame. Step 4: The entire awning is folded up, the skeleton state shrinks and the cloth is folded up, the awning frame swings down close to the skeleton straight board process, the wind measuring beam moves close to the reeling part of the sunshade cloth, the sunshade cloth is gradually rolled up, and at the same time the wall cloth itself gradually shrinks, the skeleton straight board swings close to the ground recessed frame stage, and the tail cloth itself gradually shrinks.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention controls the opening of the building awning by driving the first hinge shaft and the second hinge shaft in sequence. The building awning in the folded state before opening is fixed on the ground, which reduces the occupied space. The folded building awning can also be stored in a concave flat groove set on the ground, that is, hidden in the ground, and pedestrians and vehicles can pass above the ground.

[0016] 2. The building awning of the present invention has a safety and wind-resistant function after being unfolded. If strong winds are encountered, the strong airflow will be detected by the wind-measuring beam, and the subsequent control will break the clamping state between the wind-measuring beam and the screw rod group, and the sunshade cloth will be quickly rolled up. At the same time, the air injection group will blow air into the L-shaped long tube to break the clamping state of a row of clamps, and then the tail cloth and wall cloth will quickly shrink, and the building awning will become a wind-resistant skeleton state.

[0043] A method for operating an intelligent building awning that can be retracted to the ground comprises the following steps: Step 1: Unfold the awning. The building awning is folded and placed on the ground. First, the first hinge shaft 3 is driven to drive the frame straight plate 2 to swing upright. The frame straight plate 2 and the ground recess frame 1 are pulled apart to unfold the tail cloth 15. Then, the second hinge shaft 5 is driven to drive the shed recess frame 4 to swing flat. The frame straight plate 2 and the shed recess frame 4 are pulled apart to unfold the wall cloths 16 on both sides. The wind measuring beam 7 moves to pull the sunshade cloth 6. The sunshade cloth 6 is stretched and laid flat on the shed recess frame 4. The building awning is unfolded. Step 2: Awning protection. You can choose whether to plug the wind blocker 29 into the pressure gauge 28. Plug the wind blocker 29 into the unfolded building awning with a protection mechanism. If strong winds are encountered, the airflow causes the wind blocker 29 to swing excessively, which will automatically trigger the protection mechanism. The sunshade cloth 6 is quickly rolled up, and the clamping state of the clamp 17 connecting the tail cloth 15 and the wall cloth 16 is broken. The tail cloth 15 and the wall cloth 16 are quickly separated. The tail cloth 15 is attached to the ground recess frame 1 after shrinking as a whole, and the wall cloth 16 is attached to the shed recess frame 4 after shrinking as a whole. The building awning becomes a wind-resistant skeleton state. Step 3: The frame awning is folded up. First, the second hinge shaft 5 is driven in the reverse direction to drive the awning recess frame 4 to swing downward. The awning recess frame 4 and the frame straight plate 2 are folded together. Then, the first hinge shaft 3 is driven in the reverse direction to drive the folded awning recess frame 4 and the frame straight plate 2 to swing toward the ground recess frame 1. Step 4: The entire awning is folded up, the skeleton state shrinks and the cloth is folded up, the awning recess frame 4 swings downward close to the skeleton straight board 2, the wind measuring beam 7 moves close to the reeling position of the sunshade cloth 6, the sunshade cloth 6 is gradually rolled up, and at the same time the wall cloth 16 itself gradually shrinks, the skeleton straight board 2 swings close to the ground recess frame 1, and the tail cloth 15 itself gradually shrinks.

[0044] During the swinging and flattening stage of the shed frame 4, the wind measuring beam 7 pulls the sunshade cloth 6. The specific process is: the second hinged shaft 5 rotates to drive the shed frame 4 to swing. During the process, the gear set 10 swings along with the shed frame 4, and then the gear at one end of the surrounding edge shaft 19 engages with the stationary C-shaped rack 20 for transmission. The edge shaft 19 itself continues to rotate, and then drives the pressure shaft 22 through the ring plate gear 18, causing the screw rod 25 to rotate continuously, and the screwed walking block 23 will move to the end position of the shed frame 4, and then drive the clamped attachment block 26, and then drive the crossbeam long plate 31 through the horizontal square tube 38. The crossbeam long plate 31 pulls the edge of the sunshade cloth 6, and then the sunshade cloth 6 is gradually laid on the shed frame 4.

[0045] The principle of the strong wind protection mechanism is: the airflow causes any wind blocking body 29 to swing excessively, and the swing of the wind blocking body 29 drives the swing tube 36, causing part of the direction rod 34 to move axially. The direction rod 34 extends outward to lift the ring frame 33, and the ring frame 33 will move axially to drive the crossbeam rod 30, thereby causing the crossbeam block 40 to be pulled out from the attachment block 26. The attachment block 26 and the horizontal tube 38 are no longer fixed synchronously, and the sunshade cloth 6 always has a tendency to roll up, so that the attachment block 26 and the belt control block 24 are quickly separated. The wind-measuring beam 7 is pulled in the opposite direction by the sunshade cloth 6, and the spring 42 drives the cloth-winding shaft 8 to rotate rapidly for multiple turns, causing the sunshade cloth 6 to be quickly rolled up. In addition, the rapid rotation of the cloth-winding shaft 8 will drive the fan 44 to rotate rapidly for multiple turns, resulting in a strong airflow in the wind barrel 43. During the normal retraction process of the building awning, the motor drive will cause the awning concave frame 4 to swing slowly, corresponding to the slow retraction process of the subsequent sunshade cloth 6, that is, the cloth-winding shaft 8 rotates slowly, and the slow-rotating fan 44 will not create a strong airflow in the wind barrel 43. The strong airflow will be injected into the L-shaped long tube 14 through the concave swing pipe 45, and then the airflow will break open the door-shaped blocking plate 49, and the end of the door-shaped blocking plate 49 will be pulled out from the fixed cloth plate 47, so that the fixed cloth plate 47 can slide vertically in the control plate 46, and the edges of the joints of the tail cloth 15 and the wall cloth 16 will lose control, and then the wall cloth 16 and the tail cloth 15 will both deform and shrink.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The building sunshade is folded and placed on the ground. First, the first hinge shaft (3) is driven to drive the frame straight plate (2) to swing upright. The frame straight plate (2) and the ground recess frame (1) are pulled apart to unfold the tail cloth (15). Then, the second hinge shaft (5) is driven to drive the shed recess frame (4) to swing flat. The frame straight plate (2) and the shed recess frame (4) are pulled apart to unfold the wall cloth (16) on both sides. The wind measuring beam (7) moves to pull the sunshade cloth (6). The sunshade cloth (6) is stretched and laid flat on the shed recess frame (4). The building sunshade is unfolded. Step 2: sunshade protection. You can choose whether to plug the wind-blocking body (29) on the pressure gauge (28). Plug-in the wind-blocking body (29) can make the unfolded building sunshade have a protection mechanism. If strong winds are encountered, the wind-blocking body (29) will swing excessively due to the airflow, and the protection mechanism will be automatically triggered. The sunshade cloth (6) will be quickly rolled up, and the clamping state of the clamp (17) connecting the tail cloth (15) and the wall cloth (16) will be broken. The tail cloth (15) and the wall cloth (16) will be quickly separated. The tail cloth (15) will be attached to the ground recess frame (1) after being shrunk as a whole, and the wall cloth (16) will be attached to the shed recess frame (4) after being shrunk as a whole. The building sunshade becomes a wind-resistant skeleton state. Step 3: The frame sunshade is folded up by first driving the second hinge shaft (5) in the reverse direction to drive the awning recess frame (4) to swing downward, so that the awning recess frame (4) and the frame straight plate (2) are folded and fitted together, and then driving the first hinge shaft (3) in the reverse direction to drive the folded awning recess frame (4) and the frame straight plate (2) to swing toward the ground recess frame (1); Step 4: The entire awning is folded up, the frame state shrinks and the cloth is folded up, the awning recessed frame (4) swings downward to approach the frame straight plate (2), the wind measuring beam (7) moves close to the retracted position of the sunshade cloth (6), the sunshade cloth (6) is gradually rolled up, and at the same time the wall cloth (16) itself gradually shrinks, the frame straight plate (2) swings close to the ground recessed frame (1), and the tail cloth (15) itself gradually shrinks.
