Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , the present invention provides a new technical solution: a rolling shutter protective cover with an auxiliary guiding structure, including a rolling shutter protective shell 1, a first motor 4 is fixedly installed on the inner wall of the rolling shutter protective shell 1, and a worm 5 is fixedly installed at the output end of the first motor 4;

[0030] Among them, a winding mechanism is arranged in the rolling shutter protective shell 1, and the winding mechanism includes a rolling shutter 2, a guide strip 3, a worm gear 6, a rotating rod 7, a vertical plate 8, two brushes 9, four guide wheels 10, a groove 11, a fixed rod 12, a baffle 13, two support rods 14, a fixed rod 15, a support bar 16 and a second motor 17.

[0031] Further, the worm gear 6 is meshed and connected to the outer surface of the worm 5, the rotating rod 7 is fixedly sleeved on the inner surface of the worm gear 6, and the left end of the rotating rod 7 is rotatably connected to the inner wall of the rolling shutter protective shell 1;

[0032] Among them, the rolling shutter 2 is arranged on the outer surface of the rotating rod 7, and two guide strips 3 are respectively fixedly installed on both sides of the rolling shutter 2.

[0033] Further, the groove 11 is opened on the lower surface of the bottom plate of the rolling shutter protective shell 1, and two fixed rods 12 are respectively fixedly installed in the inner wall of the groove 11;

[0034] Among them, two baffles 13 are respectively rotatably sleeved on the outer surfaces of the two fixed rods 12, and two support rods 14 are respectively rotatably connected to the opposite surfaces of the two baffles 13.

[0035] Further, the fixed rod 15 is rotatably sleeved on the inner surfaces of the two support rods 14, and the support bar 16 is rotatably sleeved on the outer surface of the fixed rod 15.

[0036] Further, the second motor 17 is fixedly installed on the upper surface of the bottom plate of the rolling shutter protective housing 1, and the output shaft of the second motor 17 is fixedly sleeved on the inner surface of the support rod 16.

[0037] Further, two vertical plates 8 are respectively fixedly installed on the upper surface of the bottom plate of the rolling shutter protective housing 1, and two brushes 9 are respectively fixedly installed on the opposite surfaces of the two vertical plates 8;

[0038] Among them, four guide wheels 10 are respectively arranged on the opposite surfaces of the two vertical plates 8;

[0039] When the rolling shutter protective cover with the auxiliary guiding structure is in use, by starting the first motor 4, the first motor 4 drives the rotation of the worm 5 fixedly installed at the output end through operation. The worm 5 drives the rotation of the worm wheel 6 meshed on the outer surface. The worm wheel 6 rotates through the rotating rod 7 fixedly sleeved on the inner surface. At this time, the rolling shutter 2 arranged on the outer surface of the rotating rod 7 gradually moves downward between the two guide wheels 10 through the guide strips 3 fixedly installed on both sides. And during the movement, the rolling shutter 2 is cleaned by the brush 9 on the surface of the rolling shutter 2. At this time, by starting the second motor 17, the second motor 17 drives the rotation of the support rod 16 fixedly sleeved on the outer surface of the output shaft through operation. The support rod 16 drives the fixed rod 15 rotatably sleeved on the inner surface to move downward. The fixed rod 15 exerts a downward thrust on the two support rods 14 rotatably sleeved on the outer surface. The two support rods 14 exert opposite thrusts on the two baffles 13 rotatably connected at the lower end, so that they rotate on the outer surface of the fixed rod 12 and gradually become vertically arranged. At this time, it can be used to wind and unwind the rolling shutter 2. After the rolling shutter 2 is wound into the rolling shutter protective housing 1, at this time, the second motor 17 can be used to drive the two baffles 13 to gradually become horizontally arranged to close the groove 11, improving the dust-proof performance of the rolling shutter protective housing 1;

[0040] For the rolling shutter protective cover with the auxiliary guiding structure, the first motor 4 can be used to drive the winding and unwinding of the rolling shutter 2, and by using the self-locking property between the worm 5 and the worm wheel 6, the stability of the rolling shutter 2 during winding and unwinding can be maintained. And the guide wheels 10 and the guide strips 3 are arranged to prevent the rolling shutter from shaking during the winding process and maintain the stability during winding. Moreover, for the rolling shutter protective cover with the auxiliary guiding structure, the second motor 17 can be used to drive the baffle to close to block the groove 11 opened on the bottom plate of the rolling shutter protective housing 1. By this method, when the rolling shutter 2 is wound into the rolling shutter protective housing 1, a sealed environment is maintained inside, it is difficult for dust to enter, the rolling shutter 2 is prevented from being polluted, and the cleanliness of the rolling shutter 2 is maintained.

[0041] Working principle: When the rolling shutter protective cover with an auxiliary guiding structure is in use, by starting the first motor 4, the first motor 4 drives the rotation of the worm 5 fixedly installed at the output end through operation. The worm 5 drives the rotation of the worm gear 6 meshed on the outer surface. The worm gear 6 drives the rotation of the rotating rod 7 fixedly sleeved on the inner surface. At this time, the rolling shutter 2 arranged on the outer surface of the rotating rod 7 gradually moves downward between the two guiding wheels 10 through the guiding strips 3 fixedly installed on both sides. And during the movement, the rolling shutter 2 is cleaned by the brush 9 on the surface of the rolling shutter 2. At this time, by starting the second motor 17, the second motor 17 drives the rotation of the support rod 16 fixedly sleeved on the outer surface of the output shaft through operation. The support rod 16 drives the fixed rod 15 rotatably sleeved on the inner surface to move downward. The fixed rod 15 exerts a downward thrust on the two support rods 14 rotatably sleeved on the outer surface. The two support rods 14 exert opposite thrusts on the two baffles 13 rotatably connected to the lower ends, so that they rotate on the outer surface of the fixed rod 12 and gradually become vertically arranged. At this time, it can be used to wind and unwind the rolling shutter 2. After the rolling shutter 2 is wound into the rolling shutter protective shell 1, at this time, the second motor 17 can be used to drive the two baffles 13 to gradually become horizontally arranged to close the groove 11 and improve the dust-proof performance of the rolling shutter protective shell 1.
