Meanwhile, a limiting portionis arranged between the first connecting rodand the second connecting rod, and the limiting portionis configured to limit a rotation angle between the first connecting rod and the second connecting rod, so as to facilitate folding and avoid dead angles. In this embodiment, when unfolded to the maximum angle, i.e., a distance between two adjacent slide seats reaches the maximum, an included angle between the first connecting rodand the second connecting rodis less than 150°.

A plurality of louversare provided. Two ends of the louvers are respectively arranged between the slide seats on the two guide rodsand are rotatable. The driving deviceis connected with the slide seatsand configured to drive the slide seatsto slide and the louversto rotate to be folded or unfolded.

Referring to, driving wheelsare symmetrically arranged on both sides of the rectangular frame. The driving wheels are synchronous pulleys. A synchronous beltis arranged between the two driving wheelslocated on a same side. The slide seatlocated at an end portion of a free end is fixedly connected with the synchronous belt, through the rotation of the synchronous belt, the slide seat can be driven to slide horizontally, and then drives the other slide seats to slide, so as to realize unfolding or folding. A first driving shaftis arranged between the two driving wheels located at a same end, and the first driving shaftis connected with the driving deviceto drive the synchronous belts at both sides to rotate synchronously, so as to realize synchronous movement of the slide seats on both sides. The first driving shaftis horizontally arranged at an end portion of the rectangular frameand is perpendicular to a driving direction of the synchronous belt. An end portion of the first driving shaftis connected with the driving wheelthrough a universal joint to drive the driving wheel to rotate, and further realize the rotation of the belt.

In this application, the slide seatis internally provided with a worm gear and a worm. The worm is engaged with the worm gear. An end portion of the worm gear is provided with an output shaft. The output shaft is in rigid connection with the worm gear and is coaxial with the worm gear. Through the rotation of the worm gear, the louvers can be driven to rotate (turn). The worm is horizontally arranged, two ends of the worm are perforated by a shaft hole, and a cross section of the shaft hole is non-circular. In this embodiment, the cross section is polygonal. Meanwhile, the shaft hole is internally provided with a second driven shaftin a slide fit manner. The cross section of the second driven shaftis the same as that of the shaft hole in shape; preferably, the cross sections of the shaft hole and the second driven shaftare both a regular hexagon, axial sliding can be achieved therebetween; and when the second driven shaftrotates, the worm can be driven to rotate. The second driven shaftis connected with the driving deviceand configured to drive the worm to rotate, so as to finally realize turning of the louvers.

The second driving gearis engaged with a second driven gear. The second driven gearis fixedly provided with a second driving bevel gear. The second driving bevel gearis a bevel gear, i.e. an angular wheel, and is arranged downwards. Meanwhile, a second driving shaftat the end portion of the rectangular frameis provided with a second driven bevel gear. The second driven bevel gearcan be engaged with the second driving bevel gear. In this application, a distance between the first driven bevel gearand the second driven bevel gearis less than that between the first driving bevel gearand the second driving bevel gear, so that a sliding space is provided for the shell, and engagement between different gears can be achieved through sliding up and down. Specifically, when the shell slides to an upper limiting position, the first driving bevel gearis engaged with the first driven bevel gear, and at this time, the slide seats can be driven to slide horizontally; and when the shell slides to a lower limiting position, the second driving bevel gearis engaged with the second driven bevel gear, at this time, the worm gear and the worm can be driven to rotate, and further the louvers are driven to rotate. An end portion of the lower end of the main shaftis provided with an input end. The input end extends out of the shell for connecting a motor or a rocker to serve as a power input end.

In this application, the support is formed by four section bar cross beams. Each of the cross beams includes a pipe bodywith a rectangular cross section. Referring to, a vertical separator plateis arranged inside (in the cross section of) the pipe body. The vertical separator plateis arranged at one side away from the louvers and divides the interior of the pipe body into a first cavity and a second cavity, where a sectional area of the first cavity is larger than that of the second cavity. The second cavity is internally provided with one or more first horizontal separator plates, and the first horizontal separator platesdivide the second cavity into a plurality of sub-cavities. An installing portionis arranged on an inner wall of the sub-cavity, and two ends of the installing portion are perforated by a through hole for installing bolts, so as to facilitate the installation of a connecting piece or a cover. The first cavity is internally provided with a second horizontal separator plate. The second horizontal separator plateis arranged at a lower position, and divides the first cavity into an upper cavity and a lower cavity, where a sectional area of the upper cavity is larger than that of the lower cavity. The guide rods are installed on an upper surface of the second horizontal separator plate. The slide seats are arranged in the upper cavity and are in slide fit on the guide rods. An opening is formed in a side wall of the upper cavity. An upper end and a lower end of the opening are provided with baffle plates, a gap is reserved between the two baffle plates, forming an opening allowing the output shaft of the slide seat to pass through. A bottom surface of the pipe body horizontally extends inwards (in a direction approaching the louvers) and forms a first connecting portion. An end portion of the first connecting portionis bent at 90 degrees upwards and forms a second connecting portion. The first connecting portion, the second connecting portion, and the pipe body form an L-shaped trough body for shielding dust and rainwater, so as to prevent the rainwater and dust from falling through the gap, and achieve good usage experience.
