[0036] Embodiment 2:

[0037] See also Figure 1-8 As shown, on the basis of the first embodiment, the present invention provides a technical solution: the first wire wheel group 14 and the second wire wheel group 15 are symmetrically distributed on the top surfaces of both sides of the driving shaft 16, the one-way device 18 is fixedly connected to the inner tube 17, the connection relationship between the one-way device 18 and the inner tube 17 is a sliding connection, the first wire wheel group 14 and the second wire wheel group 15 are arranged in a mirror-symmetrical structure, the first wire wheel group 14 includes a wire wheel 141, and the top of one side of the wire wheel 141 is fixedly connected to a tension control spring 142, and the top of one side of the tension control spring 142 is fixedly connected to A connecting shaft 143 is connected, and the driving group 13 includes a fixed roller 131 and a tension roller 132.

[0039] In the implementation case, a driving shaft 16 and a one-way device 18 are added to the central part to achieve synchronization of the driving of the wire wheels on both sides. There are two ways to tension the curtain of the sunshade 7: the first is to tighten the driving rope 11 by the tension control spring 142 in the wire wheel 141 to perform tensioning; the second is to tighten the driving rope 11 by adding a tension roller 132 in the middle of the driving rope 11 or adding a connecting tension spring 20 at the connection position between the driving rope 11 and the slider 10 to tension the driving rope 11 to tension the sunshade 7.

[0040] Working principle:

[0041] The opening and closing action of the sunshade 7 is realized by setting the drive group 13 to drive the drive shaft 16. When the drive assembly is controlled to rotate the motor, the sunshade is driven to be fully opened or closed through the drive shaft. During the opening and closing process of the sunshade 7, the one-way device 18 controls the drive shaft 16 and the inner tube 17 to idle or rotate synchronously, thereby driving the reel group 6 or the drive wire wheel 141 to reel in the drive rope 11, and finally realizing the opening or closing of the sunshade 7;

[0042] By setting a driving shaft 16 and a one-way device 18 at the center, the synchronization of the wire wheel driving on both sides is achieved. There are two ways to tension the curtain 7: the first is to tighten the driving rope 11 by the tension control spring 142 in the wire wheel 141; the second is to tighten the driving rope 11 to tension the sunshade 7 by adding a tension roller 132 in the middle of the driving rope 11 or adding a connecting tension spring 20 at the connection position between the driving rope 11 and the slider 10;

[0043] Sunshade curtain closed: the drive group drives the drive shaft to rotate clockwise, the drive shaft links the wire wheel to rotate clockwise, the wire wheel winds the drive rope to pull the slider to move forward to close the sunshade curtain; at this time, the one-way device and the drive shaft are in an idling state;

[0044] Sunshade curtain opens: the drive group drives the drive shaft to rotate counterclockwise, and the drive shaft rotates synchronously through the one-way device to drive the inner tube to retract the fabric, so that the sunshade curtain opens. At this time, the one-way device and the drive shaft are in a synchronous rotation state.
