[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0026] Example 1: See Figures 1 to 4 As shown, an automatic retractable canopy curtain comprises a frame 1 and a canopy curtain 2 installed in the frame, one end of the canopy curtain is fixedly connected to the right end of the frame, the left side of the canopy curtain is rolled up on a retractable and reeling mechanism 3, the retractable and reeling mechanism is movably arranged on the top of the frame, the front and rear sides of the top of the frame are respectively provided with a card slot 4, and the front and rear sides of the canopy curtain are respectively clamped in the corresponding card slots;

[0027] When the retractable and unretractable winding mechanism moves to the right, the retractable and unretractable winding mechanism retracts the canopy curtain and pulls the front end and the rear end of the canopy curtain out of the corresponding slots respectively; when the retractable and unretractable winding mechanism moves to the left, the retractable and unretractable winding mechanism retracts the canopy curtain and clamps the front end and the rear end of the canopy curtain in the corresponding slots respectively;

[0028] Flexible strips 5 are respectively provided on the front and rear sides of the canopy curtain, and the front and rear sides of the canopy curtain are respectively clamped in the corresponding clamping slots through the flexible strips.

[0029] In this embodiment, taking an outdoor awning or sun room as an example, the awning curtain is arranged at the top to play the role of sunshade, windproof and rainproof. In actual use, when the retracting and unreeling mechanism is reeling, since the right end of the awning curtain is in a fixed state, when the awning curtain is reeled, the retracting and unreeling mechanism will move to the right to realize the opening of the awning curtain. When the awning curtain needs to be closed, the retracting and unreeling mechanism is unreeled, and in this process, the retracting and unreeling mechanism moves to the left. At the same time, in this embodiment, the right side of the awning curtain is limited by the right end of the frame, and the left side is limited by the retracting and unreeling mechanism. In order to prevent the front and rear sides of the awning curtain from shaking and affecting the normal use of the awning curtain, therefore, the front and rear sides of the top of the frame are respectively provided with a card slot, and the front and rear ends of the awning curtain are provided with a flexible strip, and the flexible strip is stuck in the card slot, so that the front and rear sides of the awning curtain can be limited, preventing wind, rain, sun, etc. from entering from the gap between the awning curtain and the frame, and also preventing the awning curtain from being blown up and damaged when the outside wind blows. When the awning curtain is rolled up to open, the flexible strip is pulled out of the corresponding card slot for rolling up. When the awning curtain is unrolled to close, the flexible strip is pressed into the corresponding card slot to limit the front and rear ends of the awning curtain.

[0030] See also Figures 1 to 4 As shown, the reeling and unreeling mechanism includes a housing 6, a reeling shaft 7 mounted on the housing, a motor 8 and two groups of transmission parts. The reeling shaft is rotatably mounted in the housing, the output shaft of the motor is connected to one end of the reeling shaft, and the two groups of transmission parts are respectively arranged on the outside of the housing. The front and rear ends of the frame are respectively provided with transverse slide rails 9, and each group of transmission parts is installed on the transverse slide rails at both ends. A strip through slot 10 is provided at the bottom of the housing, and the left side of the canopy curtain passes through the strip through slot and is wound on the reeling shaft. A gap is provided between the bottom of the housing and the top surface of the frame. A transmission roller 11 is provided at the strip through slot to guide the retraction and unfolding of the canopy curtain.

[0031] In this embodiment, the motor drives the winding shaft and two sets of transmission parts to rotate synchronously, so that when the winding shaft rotates, not only can the canopy curtain be wound and unwound through the winding shaft, but it can also move left and right on the frame synchronously through the transmission parts and the horizontal slide rail to realize the opening and closing of the canopy curtain.

[0032] See also Figures 1 to 4As shown, the transmission member includes a transmission gear 12 and two groups of support wheels 13, a vertical plate 14 is respectively provided at both ends of the shell, the top of the vertical plate is vertically connected to the end of the shell, the vertical plate is arranged on the outside of the frame, the transmission gear is rotatably installed on the inner side of the bottom of the vertical plate, the support wheel is rotatably installed on the upper inner side of the vertical plate, the support wheel is arranged at the bottom of the shell, the bottom outer edge surfaces of the two groups of support wheels are against the top surface of the frame, and the support wheels are arranged on the outer side of the corresponding card slot; a rack 15 is provided at the bottom of the transverse slide rail, the top outer edge surface of the transmission gear is meshed with the rack of the transverse slide rail, and the end of the winding shaft is meshed with the corresponding transmission gear through a belt 21.

[0033] In this embodiment, when the reel rotates, the canopy curtain is reeled or unreeled. When it rotates, the corresponding transmission gear is driven to rotate by the belt. When the transmission gear rotates, it moves left and right through the corresponding rack, ensuring that the canopy curtain moves synchronously during the reeling and unreeling process. At the same time, the two sets of support wheels are used to support and limit the shell to prevent it from falling downward and contacting the top surface of the frame. At the same time, the transmission gear and the rack can also limit the upward movement of the shell and the up and down movement of the shell. In order to prevent the shell from tilting and causing the shell to directly contact the top surface of the frame, two sets of support wheels and one set of transmission gears are used to support and limit the horizontal position of the shell.

[0034] See also Figures 1 to 4 As shown, an annular protrusion 16 is provided on the outer edge surface of the support wheel, the outer end surface of the annular protrusion is flush with the outer end surface of the support wheel, and the inner wall of the annular protrusion abuts against the outer wall of the frame.

[0035] By setting the annular protrusion, the forward and backward movement of the shell can be limited to ensure the accurate left and right movement position of the shell, that is, to ensure the accurate movement trajectory during the folding and unfolding of the skylight curtain, and to ensure the stability and quality of the folding and unfolding.

[0036] See also Figure 3 , 4 As shown, the slot is an arc-shaped structure, and the top opening width of the slot is smaller than the middle width of the slot; the diameter of the flexible strip is larger than the width of the slot, and the diameter of the flexible strip is smaller than the middle width of the slot; when the canopy curtain is in the rolled-up state, the flexible strip is pulled out from the corresponding slot and rolled up on the retracting and unrolling mechanism; when the canopy curtain is in the unrolled state, the flexible strip is clamped in the corresponding slot through the retracting and unrolling mechanism.

[0037] In this embodiment, the slot is an arc-shaped structure with a smaller top opening width. The flexible strip is elastic and can be elastically deformed. In this way, after the flexible strip is inserted into the slot, the canopy curtain will droop downward due to a certain gravity in the middle part due to the weight. In this way, the top opening of the slot will clamp the flexible strip, thereby ensuring the stability and quality of the canopy curtain.

[0038] In this embodiment, the diameters of both ends of the rolling shaft are smaller than the diameter in the middle, so that when the awning curtain is rolled up, the flexible strip will be at a smaller diameter, preventing the two ends of the awning curtain from protruding when it is rolled up.

[0039] See also Figures 1 to 4 As shown, a retracting and releasing auxiliary mechanism is respectively provided at both ends of the retracting and releasing winding mechanism, and the retracting and releasing auxiliary mechanism is respectively arranged opposite to a group of the card slots, and the auxiliary mechanism assists in pulling the flexible strip out of the card slot, or inserting the flexible strip into the card slot.

[0040] In this embodiment, since the width of the flexible strip is greater than the width of the top opening of the slot, the flexible strip needs to be pulled out of and pressed into the slot when the reeling and unreeling mechanism reels and unreeles the product. Under normal circumstances, when the awning curtain is reeled in, the reeling force can be used to pull the flexible strip out of the slot, but the pulling out is not smooth enough. When unreeling, in order to press the flexible strip into the slot, the reeling and unreeling auxiliary mechanism is used to pull the flexible strip out of the slot when the awning curtain is reeled in, and press the flexible strip into the slot when the awning curtain is unreeled.

[0041] See also Figures 1 to 4 As shown, the auxiliary mechanism includes a push plate 17 and a pressing piece, the push plate is arranged on the left side of the pressing piece, the top of the push plate is installed on the bottom surface of the winding and unwinding mechanism, the push plate is arranged downwardly from left to right, the bottom of the push plate is inserted in the card slot, and the push plate is arranged at the lower left side of the flexible strip inside the card slot; the pressing piece is installed on the right side surface of the winding and unwinding mechanism, the pressing piece is arranged above the top surface of the frame, and the pressing piece is arranged above the top surface corresponding to the flexible strip.

[0042] The setting of the push plate, due to the certain distance between the reel and the top surface of the frame, the position where the awning curtain is connected with the card slot is set downward from left to right, that is, it is inclined between the bar-shaped through slot of the shell and the card slot. When the awning curtain is rolled up, the push plate will be inside the card slot, and the bottom surface of the right end of the push plate will be against the bottom surface of the flexible strip. When moving to the right, the push plate squeezes the flexible strip and pushes it to the upper right, squeezing the flexible strip out from the opening at the top of the card slot, so that the reel can be rolled up. When unwinding, the pressing piece moves to the left and presses the unrolled flexible strip into the card slot, so that the flexible strip is inserted into the card slot.

[0043] See also Figures 1 to 4 As shown, the pressing member includes a transverse plate 18, a left pressure rod 19 and a right pressure rod 20. The left side of the transverse plate is vertically connected to the right side surface of the rewinding and unwinding mechanism. The transverse plate is arranged above the outer side of the frame. The outer ends of the left pressure rod and the right pressure rod are respectively rotatably connected to the transverse plate. The left pressure rod and the right pressure rod are both arranged above the corresponding flexible strip.

[0044] The left pressure rod is arranged above the left side of the right pressure rod, and the bottom outer edge surface of the right pressure rod is arranged close to the top surface of the frame; the top surfaces of the left pressure rod and the right pressure rod are arranged parallel to the top surface of the frame.

[0045] Among them, the distance between the right pressure rod and the top surface of the frame is the thickness of the awning curtain. When the retracting and unwinding mechanism moves to the left, when the awning curtain is unrolled and moves to the left, the left pressure rod and the right pressure rod move to the left synchronously, and the left pressure rod is located above the left side of the right pressure rod. The left pressure rod first presses down the flexible strip on the side of the unrolled awning curtain, so that the flexible strip is close to the slot, and then the right pressure rod directly presses the flexible strip into the slot, so that the flexible strip is inserted into the slot, which is convenient and quick. In this way, in the process of the retracting and unwinding mechanism retracting and unwinding the awning curtain, the flexible strip can be pulled out of the slot or inserted into the slot, which is efficient and of good quality, ensuring the stability and quality of the awning curtain.

[0046] See also Figures 1 to 3 As shown, a pressure roller 22 is rotatably mounted on the horizontal plate, and the pressure roller is arranged on the right side of the right pressure rod. The width of the pressure roller is smaller than the width of the top opening of the slot, and the bottom outer edge surface of the pressure roller is arranged in the slot.

[0047] In this embodiment, the right pressure rod will press the flexible strip into the slot, but the flexible strip will be in the opening at the top of the slot. Through the setting of the pressure roller, the flexible strip in the opening at the top of the slot will be pressed into the slot, so that the opening of the slot can clamp the flexible strip and prevent the flexible strip from being pulled out directly from the opening at the top of the slot due to weight.
