The shape of the fixing member 35 may be set as desired.

As shown in fig. 2 and 4, the sliding member 36 is disposed on the driving belt 32, and can move along with the driving belt 32, so as to drive the awning cloth 20 to be folded and folded. Each set of slides 36 includes a driving slide 361 and a plurality of driven slides 362, respectively. One end of the driving sliding member 361 is fixedly connected with the driving belt 32, and can move synchronously with the driving belt 32. The driving sliding member 361 is located at an end far away from the fixing member 35, one end of the driving sliding member is fixedly connected with the driving belt 32, and the top end of the driving sliding member is fixedly connected with the canopy rod 50. The driven sliding members 362 are respectively located between the driving sliding member 361 and the fixed member 35, and are not fixedly connected with the driving belt 32, and the driven sliding members 362 are moved by the driving sliding member 361. The top ends of the driven sliding members 362 are fixedly connected to the canopy bars 50, respectively.

As shown in fig. 1 to 4, the canopy bar 50 is disposed between the first canopy post 111 and the second canopy post 112 in a transverse direction, and extends in a direction perpendicular to the driving direction of the driving belt 32 and perpendicular to the canopy post 11. The canopy bars 50 have a length that is related to the distance between the first canopy post 111 and the second canopy post 112, and typically have a length that is approximately equal to the distance between the first canopy post 111 and the second canopy post 112. The number of the canopy bars 50 can be set according to the need, and the number thereof is related to the number of the sliding members 36 and the fixing members 35. For the present embodiment, the number of the canopy bars 50 is half of the sum of the number of the sliding pieces 36 and the fixing pieces 35, i.e., one fixing piece 35 is provided at each of both ends of one canopy bar 50, or one sliding piece 36 is provided each.

The canopy bars 50 are connected to the awning cloth 20, and the canopy bars 50 should be spaced below the awning cloth 20 when the awning cloth 20 is fully opened. The connection between the canopy bars 50 and the awning cloth 20 may be referred to in the art. The movement of the canopy bar 50 can drive the awning cloth 20 to fold and collapse.

As shown in fig. 2, 5 and 6, since the driven sliding member 362 is moved by the driven sliding member 361, in order to ensure that the canopy rod 50 moves along a straight line, guide rods 38 are respectively provided on the lateral brackets 12, and the guide rods 38 are used for restraining the sliding members 36 to move along a straight line in a limited manner.

As shown in fig. 2, the guide rods 38 are provided at both ends of the canopy rod 50, and extend in a direction parallel to the driving direction of the driving belt 32. In this embodiment, a total of 4 guide bars 38 are provided. The shape of the guide bar 38 may be set as desired. The guide bar 38 may be a long straight bar or a guide rail, which can limit the movement of the sliding member 36 along the direction of the guide bar 38.

As shown in fig. 2, 5 and 6, the sliding member 36 is movably connected to the guide rod 38, and can perform a limiting movement along the extending direction of the guide rod 38.

When the driving motor 31 works, it drives the first driving wheel 33 to rotate so that the driving belt 32 drives. Since the fixing member 35 is fixed to the lateral bracket 12, the fixing member 35 does not move when the belt 32 is driven; the driving sliding member 361 is fixedly connected to the driving belt 32, so that the driving sliding member 361 moves synchronously with the driving belt 32 when the driving belt 32 drives.

As shown in fig. 4, when the driving belt 32 drives toward the fixing member 35, the driving sliding member 361 moves toward the fixing member 35 synchronously, and when the driving belt moves to an adjacent driven sliding member 362, the driving sliding member 361 pushes the driven sliding member 362 to move along the fixing member 35, and the driving belt is sequentially transferred to enable the sliding members 36 to retract toward the fixing member 35. The top ends of the sliding members 36 are fixedly connected with the canopy bars 50, so that when the sliding members 36 are folded toward the fixing members 35, the canopy bars 50 are synchronously folded toward the fixing members 35. And the awning lever 50 is connected with the awning cloth 20, when the awning lever 50 is folded towards the fixing piece 35, the awning cloth 20 is synchronously folded towards the fixing piece 35, so that the awning cloth can be folded and folded at the fixed end 122 of the transverse bracket 12, and the state is shown in fig. 4.

As shown in fig. 2 and 9, when the belt 32 is driven in a direction away from the fixed member 35, the driving slider 361 moves in synchronization in a direction away from the fixed member 35; the movement of the driving sliding member 361 can drive the awning cloth 20 to open in a direction away from the fixing member 35, the awning cloth 20 is connected with the awning rod 50, and the awning rod 50 is connected with the driven sliding member 362, so that the movement of the driving sliding member 361 can be transmitted to the driven sliding member 362 through the awning cloth 20 and the awning rod 50, and the driven sliding member 362 can be pulled to move in a direction away from the fixing member 35, so that the awning cloth 20 can be opened, and the state is shown in fig. 2.

Since the driving sliding member 361 and the driven sliding member 362 both perform the limiting movement along the guide rod 38, the sliding members 36 can move linearly when moving, and thus the awning cloth 20 can be folded and folded smoothly.

The shape of the sliding member 36 may be set according to need, and in this embodiment, as shown in fig. 5 and 6, the sliding member 36 includes an upper connection portion 363 and a lower connection portion 364. The upper connection portion 363 and the lower connection portion 364 may be integrally formed or fixedly connected, and may be specifically set as required. The upper connecting portion 363 is used for fixedly connecting with the canopy rod 50, and the lower connecting portion 364 is used for limiting connection with the guide rod 38. In this embodiment, the lower connection portion 364 includes a first plate portion 365 and a second plate portion 366 spaced in parallel, and the first plate portion 365 and the second plate portion 366 are connected by a third plate portion 367. The first plate portion 365 is connected to the upper connection portion 363, and the second plate portion 366 faces the guide rod 38. At least two limiting wheels 368 are provided on the surface of the second plate portion 366 facing the guide rod 38, and the limiting wheels 368 are spaced in parallel and distributed on both sides of the guide rod 38. The guide rod 38 is located between the guide wheels 37, the surface of the limit wheel 368 matches with the surface of the guide rod 38, and the sliding member 36 can be ensured to move along the direction of the guide rod 38 by the restraining action between the limit wheel 368 and the guide rod 38.

For this embodiment, as shown in fig. 5 and 6, the first plate 365 of the active sliding element 361 is connected to the driving belt 32 by a chain clip 39, so that the active sliding element 361 can move synchronously along with the driving belt 32 and can move along the guide rod 38 in a limited manner.
