[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0018] In this embodiment, by Figure 1-Figure 3 As shown, the present invention includes a rolling shutter box 3, a rolling shutter roller 1 is rotatably installed inside the rolling shutter box 3, a motor is fixedly installed at one end of the rolling shutter box 3, and the output shaft of the motor is fixedly connected to one end of the rolling shutter roller 1, a rolling shutter door 2 is wound on the surface of the rolling shutter roller 1, and the bottom end of the rolling shutter door 2 extends downward through the rolling shutter opening at the bottom end of the rolling shutter box 3, and a rolling shutter guide frame 4 is installed on both sides of the rolling shutter door 2, a guide shell 5 is fixed to the bottom of the rolling shutter door 2, a driving assembly is provided in the middle of the guide shell 5, and a driving shell 6 is fixed at both ends of the driving assembly, an anti-falling assembly is provided in the two driving shells 6, and a guide rack 7 is provided on the two rolling shutter wire frames, and the anti-falling assembly drives the anti-falling through the guide rack 7;

[0019] When the rolling door 2 needs to be driven up by the motor, the anti-falling component is first driven by the control driving component to move toward the guide rack 7, and cooperates with the guide rack 7 to form an anti-falling protection. When the rolling door 2 fails and falls off during the rising process, the anti-falling component cooperates with the guide rack 7 to limit the rolling door 2 from falling, thereby preventing the garage rolling door 2 from falling;

[0020] When the rolling door 2 is driven by the motor to descend, the driving assembly drives the anti-fall assembly to move away from the guide rack 7, and disengages from the guide rack 7. At this time, the rolling door 2 can descend.

[0021] In this embodiment, by Figure 2 and Figure 4As shown, the drive assembly includes a first motor 8 fixed to the rear of the guide housing 5, a first gear 9 is fixed to the output end of the first motor 8, and two matching racks 10 are respectively engaged on the upper and lower sides of the first gear 9. The two matching racks 10 are respectively fixed on two drive housings 6, and the two drive housings 6 are respectively located on the left and right sides of the guide housing 5. The matching racks 10 and the drive housing 6 are both slidably connected in the guide housing 5;

[0022] The operation of the first motor 8 drives the first gear 9 to rotate, and the first gear 9 drives the two mating racks 10 to move. The movement directions of the two mating racks 10 are opposite, and the two drive shells 6 can be mobilized at the same time to approach the first motor 8 or move away from the first motor 8, thereby controlling the anti-fall component to cooperate or disengage with the guide rack 7.

[0023] In this embodiment, by Figure 2-Figure 3 As shown, the two drive housings 6 are symmetrically mounted with respect to the first motor 8 .

[0024] In this embodiment, by Figure 2-Figure 3 As shown, the anti-fall assembly includes a guide gear 11 rotatably connected to the drive housing 6, the side of the guide gear 11 is engaged with the guide rack 7, the lower part of the guide gear 11 is engaged with the limit rack 12, and the limit plate 13 is fixed to the side of the limit rack 12 close to the first motor 8. A spring 14 is provided in the drive housing 6, one end of the spring 14 is fixed to the side of the limit plate 13 close to the first motor 8, and the other end of the spring 14 is fixed to the side of the drive housing 6 close to the limit plate 13;

[0025] When the rolling door 2 needs to be driven up by the motor, the driving assembly drives the driving housing 6 to the guide rack 7, and the guide gear 11 is engaged with the guide rack 7. At this time, when the motor drives the rolling door 2 to rise, the guide gear 11 moves upward with the driving housing 6, and the guide gear 11 cooperates with the guide rack 7 to rotate continuously. The driving gear on the left side of the rolling door 2 is reversed, and the driving gear on the right side of the rolling door 2 rotates forward. The driving gear will continuously push the limit rack 12 and the limit plate 13 to move toward the direction of the first motor 8, and the limit plate 13 will continuously squeeze the spring 14. At this time, the rolling door 2 rises normally;

[0026] When the rolling door 2 falls due to a problem, the rolling door 2 descends and drives the driving gear downward. At this time, the driving gear on the left side of the rolling door 2 rotates forward, and the spring 14 pushes the limit plate 13 and the limit rack 12 to engage with the driving gear. The rotation of the driving gear drives the limit rack 12 and the limit plate 13 to move toward the rolling guide frame 4. The movement of the limit plate 13 will press against the driving gear, limiting the rotation of the driving gear. The driving gear stops rotating and presses against the guide rack 7, limiting the driving housing 6 and the guide housing 5 from descending, thereby limiting the rolling door 2 from falling.

[0027] When the rolling door 2 is driven by the motor to descend, the anti-falling assembly is driven by the driving assembly to disengage the guide rack 7, and the rolling door 2 can be lowered normally;

[0028] The present application can also connect the first motor 8 to an external control device through a wire. When a problem occurs during the descent of the rolling door 2, the first motor 8 can be directly controlled by the external control device to drive the anti-fall component and the guide rack 7 to limit the descent of the rolling door 2.

[0029] The above-mentioned rotational connections are all rotationally connected through bearings.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
