DETAILED DESCRIPTION

[0022] Reference Figure 1-5 As shown, a transmission assembly includes a crossbeam 2, the transmission assembly 1 is installed in the middle area inside the crossbeam 2, a transmission shaft 3 is provided passing through the transmission assembly 1, and the transmission assembly 1 is located in the middle of the transmission shaft 3. When the transmission assembly 1 is started, it drives the transmission shaft 3 to rotate as a whole.

[0023] like Figure 4 As shown, the transmission assembly 1 includes a housing 101, in which a worm wheel 102 and a worm 103 are arranged. The worm 103 is meshingly arranged on one side of the worm wheel 102, and the axial center of the worm wheel 102 is provided with a through hole 4 that matches the axial direction of the transmission shaft 3. The through hole 4 here can be a square or a hexagon, and the shape is not limited. A hinge ring is arranged below the worm 103, and a rocker with a hook is also provided to be hooked in the hinge ring. The rotation of the worm 103 is controlled by rotating the rocker.

[0024] Since the transmission shaft 3 needs to cooperate with the transmission assembly 1 and the components on both sides, the overall shape of the transmission shaft 3 is more variable. The transmission shaft 3 is segmented, and the through hole 4 on the traditional worm gear 102 is a four-corner. The transmission shaft 3 includes a first shaft body 31 arranged in the transmission assembly 1 and a second shaft body 32 located on both sides of the first shaft body 31. A bushing 5 is provided at the connection between the first shaft body 31 and the second shaft body 32. By fixing the first shaft body 31 and the second shaft body 32 on the bushing 5, the mutual fixation of the first shaft body 31 and the second shaft body 32 is achieved.

[0025] In order to ensure that there is no friction or collision between the through hole 4 and the first shaft body 31 , chamfers 6 are provided at the four corners of the first shaft body 31 .

[0026] The transmission assembly 1 is located in the middle of the first shaft 31. In order to ensure the cooperation between the second shaft 32 and the components on both sides, the second shaft 32 is hexagonal, and one end surface of the second shaft 32 is in contact with one end surface of the first shaft 31. Specifically, Figure 5As shown, a convex corner 7 is arranged on the second shaft body 32 and in the axial direction. The convex corner 7 is an oblique triangle and is arranged on one of the outer hexagonal sides. Moreover, the convex corner 7 is at the edge of its hexagonal side. This arrangement is to ensure that the left and right sides have a "fool-proof" effect when installing the second shaft body 32.

[0027] like Figure 4 As shown, a universal shaft hole 8 is provided on the shaft sleeve 5, and the junction of the first shaft body 31 and the second shaft body 32 is located in the middle position of the shaft sleeve 5. At least two groups of threaded holes 9 are provided on the shaft sleeve 5. Specifically, the threaded holes 9 are located on both sides of the shaft sleeve 5. The two groups of threaded holes 9 are respectively aligned with the first shaft body 31 and the second shaft body 32. The first shaft body 31 and the second shaft body 32 are respectively connected through the shaft sleeve 5 by setting bolts.

[0028] A sunshade comprises a crossbeam 2, louvers 12, and a driving assembly 11. The driving assembly 11 is used to drive multiple groups of louvers 12 to flip simultaneously. The transmission assembly 1 is arranged in the middle of the crossbeam 2 and is located in the axial middle position of the louvers 12. In order to fix the transmission assembly 1 in the middle of the crossbeam 2, a bracket 10 is arranged in the middle of the crossbeam 2. The bracket 10 is L-shaped, and one end face of the bracket 10 is attached to the surface of the crossbeam 2, and the other end face is attached to the transmission assembly 1. Specifically, the side face of the bracket 10 is attached to the worm gear 102. The transmission assembly 1 is provided with bolts that penetrate the transmission assembly 1 and are screwed into the bracket 10.

[0029] The working process of the utility model is as follows: the transmission shaft 3 in the disassembled state is firstly, the first shaft body 31 is passed through the through hole 4 on the worm gear 102, so that the transmission assembly 1 is located in the middle of the first shaft body 31, and the second shaft bodies 32 on both sides are respectively embedded in the driving assemblies 11 on both sides, and the other side is attached to the first shaft body 31, and the sleeve 5 is placed in the middle of the first shaft body 31 and the second shaft body 32, and the connection between the first shaft body 31 and the second shaft body 32 is ensured by tightening the bolts.

[0030] The above is only an embodiment of the present invention and does not limit the present invention in any form. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present invention all fall within the protection scope of the present invention.
