[0024] The folding canopy guide rail synchronous belt 2 is arranged in the shell 1, and a through hole 11 is opened at the end of the shell 1, and the opening direction of the through hole 11 is perpendicular to the folding canopy guide rail synchronous belt 2, and the folding canopy transmission wheel 3 penetrates into the through hole 11 and meshes with the folding canopy guide rail synchronous belt 2;

[0025] The end of the through hole 11 in the opening direction is provided with the side cover 4 of the folding canopy guide rail rear support assembly, and the side cover 4 of the folding canopy guide rail rear support assembly is detachably connected to the shell 1 .

[0026] like Figure 1As shown, in this embodiment, the housing 1 includes a folding awning guide rail rear support assembly 14 and a folding awning guide rail 15 that are connected to each other. The interior of the folding awning guide rail rear support assembly 14 is used to set the folding awning guide wheel 3, and the interior of the folding awning guide rail 15 is used to set the folding awning guide rail synchronous belt 2. The folding awning guide rail synchronous belt passes through the folding awning guide rail 15 and then extends into the folding awning guide rail rear support assembly 14 to engage with the folding awning guide wheel 3. Specifically, a slit 13 is provided on one side of the folding awning guide rail 15 that is perpendicular to the opening direction of the through hole 11, and is used to install a slider or a power rod. The slider or the power rod passes through the slit 13 and is connected to the folding awning guide rail synchronous belt 2. When the folding awning guide rail synchronous belt 2 moves, it can drive the slider or the power rod to move, thereby driving the folding curtain connected to the slider or the power rod to move.

[0027] In the folding canopy guide rail rear support assembly structure which is convenient for replacing the synchronous belt, since the folding canopy guide rail rear support assembly side cover 4 is detachably connected to the shell 1, after disassembling the folding canopy guide rail rear support assembly side cover 4, the through hole 11 will be exposed, so that the folding canopy guide wheel 3 can be taken out from the through hole 11. After taking out the folding canopy guide wheel 3, the folding canopy guide rail synchronous belt 2 can be seen through the through hole 11, and the folding canopy guide rail synchronous belt 2 can be taken out from the through hole 11. Similarly, the installation of the folding canopy guide rail synchronous belt 2 can be achieved by the reverse steps. Since the shell 1 does not need to be disassembled during the entire operation process, the operation steps can be simplified and the efficiency can be improved.

[0028] It is worth noting that if Figure 1 , 2 As shown in FIG. 4 , the outer circumference of the folding canopy transmission wheel 3 is provided with external teeth 31 to mesh with the folding canopy guide rail synchronous belt 2 , and the inner circumference of the folding canopy transmission wheel 3 is provided with internal teeth 32 to connect with the output shaft of the motor.

[0029] In this embodiment, the arrangement direction of the outer teeth 31 of the folding canopy drive wheel 3 is perpendicular to the opening direction of the through hole 11. In order to cooperate with the outer teeth 31 of the folding canopy drive wheel 3, the folding canopy guide rail synchronous belt 2 needs to be provided with teeth that are consistent with the arrangement direction of the outer teeth 31 of the folding canopy drive wheel 3. In this way, after the folding canopy guide rail rear support assembly side cover 4 is disassembled, the folding canopy drive wheel 3 can move relative to the folding canopy guide rail synchronous belt 2 in the opening direction of the through hole 11, so that the folding canopy drive wheel 3 can be taken out of the through hole 11. The inner teeth 32 provided on the inner circumference of the folding canopy drive wheel 3 can be driven by the output shaft of the motor to rotate without slipping.

[0030] Optionally, wear-resistant rings 33 are provided on both sides of the folding canopy transmission wheel 3 parallel to the opening direction of the through hole 11;

In this way, after the folding canopy transmission wheel 3 is set in the through hole 11, and then the side cover 4 of the folding canopy guide rail rear support assembly is installed, the convex ring 42 of the side cover 4 of the folding canopy guide rail rear support assembly can be covered with the wear-resistant ring 33, thereby limiting the folding canopy transmission wheel 3, wherein the wear-resistant ring 33 can rotate relative to the convex ring 42, so that the folding canopy transmission wheel 3 cannot move in the left and right directions, but can rotate with the output shaft of the motor.

[0033] Preferably, Figure 1 and 3 As shown, a shaft hole 43 is opened in the middle of the bottom plate 41, and the shaft hole 43 is connected with the through hole 11. In this way, after the folding canopy guide rail rear support assembly side cover 4 is installed, the output shaft of the motor can pass through the shaft hole 43 and be fixedly connected with the folding canopy drive wheel 3 located in the through hole 11, thereby driving the folding canopy drive wheel 3 to rotate.

[0034] Specifically, Figure 1 and 3 As shown, the edge of the bottom plate 41 is provided with a flange 44, and the flange 44 is provided with a screw hole 45. The shell 1 is provided with a mounting hole 12. The screw hole 45 cooperates with the mounting hole 12 to achieve a detachable connection between the side cover 4 of the folding awning guide rail rear support assembly and the shell 1. The flange 44 and the bottom plate 41 are integrally formed to facilitate processing. After aligning the screw hole 45 with the mounting hole 12, the detachable connection between the side cover 4 of the folding awning guide rail rear support assembly and the shell 1 can be achieved by screws or bolts. Figure 1 and 6 As shown, preferably, the folding awning guide rail rear support assembly 14 includes two single-sided support members 141 that are buckled together on the left and right sides, and the mounting hole 12 is opened in the single-sided support member 141. After the long nut 142 is set in the mounting hole 12, the two single-sided support members 141 are connected. In addition, after the long nut 142 is set, it is also convenient to lock the screws or bolts when installing the side cover 4 of the folding awning guide rail rear support assembly.

[0035] Optional, such as Figure 1 and 5 As shown, the two ends of the through hole 11 in the opening direction are provided with the folding canopy guide rail rear support assembly side covers 4, and the folding canopy guide rail rear support assembly side covers 4 are detachably connected to the housing 1. In this way, the folding canopy guide rail rear support assembly side covers 4 in both left and right directions can be disassembled, and the folding canopy drive wheel 3 can be taken out from the left or right side of the housing 1, which improves the flexibility of disassembly.
