[0030] Example 1:

[0031] A rolling shutter door electric drive system, designed to ensure user safety in unexpected situations, such as... Figure 1-8As shown, the device includes a top mounting box 5 installed on the wall, an outer frame 28, and a roller shutter body 3 slidably connected to the inner wall of the outer frame 28. The top mounting box 5 is welded to the top outer wall of the outer frame 28. A motor 6 is bolted to the bottom inner wall of the top mounting box 5. The output end of the motor 6 is connected to a winding roller 10 via a key. The roller shutter body 3 is wound around the outer side wall of the winding roller 10. A movable seat 23 is welded to the bottom outer wall of the roller shutter body 3. The movable seat 23 is slidably connected to the inner wall of the outer frame 28. A limit plate 22 is welded to the outer side wall of the movable seat 23. A rotating cylinder 18 is rotatably connected to the inner side wall of the top mounting box 5. A worm gear 7 is welded to the outer side wall of the rotating cylinder 18. The worm gear 7 and the outer side wall of the rotating cylinder 18 are respectively provided with a variable pitch groove 14 and a moving groove 15. A transmission assembly is rotatably connected to the inner wall of the top mounting box 5. The transmission assembly and... The worm gear 7 meshes with the top mounting box 5. A support rod 11 is welded to the bottom inner wall of the top mounting box 5. A fixed cylinder 8 is welded to the top outer wall of the support rod 11. An outer rod 21 is slidably connected to the inner side wall of the fixed cylinder 8. A limiting plate 13 is welded to the outer side wall of one end of the outer rod 21. The limiting plate 13 cooperates with the limiting plate 22. An inner rod 20 is rotatably connected to the inner side wall of the fixed cylinder 8. The inner rod 20 and the outer rod 21 are slidably connected to each other. A connecting plate 17 is welded to the other end of the inner rod 20. A matching rod 16 is rotatably connected to the outer side wall of the connecting plate 17. The matching rod 16 cooperates with the variable pitch slide groove 14. A bent rod 9 is slidably connected to the inner side wall of the top mounting box 5. A matching rod 29 is rotatably connected to one end of the bent rod 9. The matching rod 29 cooperates with the moving slide groove 15. The other end of the bent rod 9 is rotatably connected to the outer side wall of the outer rod 21.

[0032] In use, the motor 6 is turned on to drive the winding roller 10 to wind up the main body 3 of the roller shutter. Then, the worm gear 7 and the rotating drum 18 are rotated through the transmission assembly. When the worm gear 7 and the rotating drum 18 rotate at the same time, the cooperating rod 19 outside the bending rod 9, in cooperation with the moving slide 15, causes the bending rod 9 to drive the outer rod 21 to move forward. Then, the variable pitch slide 14, in cooperation with the cooperating rod 16, causes the connecting plate 17 to drive the inner rod 20, the outer rod 21 and the outer limiting plate 13 to rotate. After rotation, the limiting plate 13 is locked at the bottom of the limiting plate 22. Even if the motor 6 is damaged, the moving seat 23 will abut against the limiting plate 22, and the main body 3 of the roller shutter will not fall directly due to gravity, thus protecting the user.

[0033] The transmission assembly includes a mounting box 1 and a connecting rod 4. The mounting box 1 is welded to the outer side wall of the outer frame 28. A second bevel gear 25 is rotatably connected to the inner wall of the mounting box 1. A handle 27 is welded to the outer side wall of the second bevel gear 25. The connecting rod 4 is rotatably connected to the inner wall of the mounting box 1. A first bevel gear 24 is welded to the bottom outer wall of the connecting rod 4. The first bevel gear 24 meshes with the second bevel gear 25. A worm gear 12 is welded to the top outer wall of the connecting rod 4. The worm gear 12 meshes with a worm wheel 7.

[0034] In use, the user can rotate the bevel gear 25 by turning the handle 27, which will cause the bevel gear 24 to drive the connecting rod 4 to rotate, and then the worm gear 12 at the top of the connecting rod 4 will be engaged to make the worm wheel 7 rotate, thus realizing manual opening and locking protection.

[0035] The outer frame 28 has a control panel 2 welded to its outer sidewall, and a locking component is slidably connected inside the outer frame 28. The locking component cooperates with the handle 27.

[0036] When in use, the device can be turned on via the control panel 2. At the same time, the locking component can be released from locking the handle 27 after the main body 3 of the roller shutter door is rolled up, allowing the user to open the protective structure.

[0037] Working principle: When in use, the motor 6 is turned on to drive the winding roller 10 to wind up the main body 3 of the roller shutter. The device is opened through the control panel 2. At the same time, the locking component can be released from locking the handle 27 after the main body 3 of the roller shutter is wound up. By rotating the handle 27, the bevel gear 25 meshes, causing the bevel gear 24 to drive the connecting rod 4 to rotate. This, in turn, engages the worm gear 12 at the top of the connecting rod 4, causing the worm wheel 7 to rotate. When the worm wheel 7 and the rotating cylinder 18 rotate simultaneously, the cooperating rod 19 outside the bending rod 9, in cooperation with the moving slide 15, causes the bending rod 9 to drive the outer rod 21 to move forward. Then, the variable pitch slide 14, in cooperation with the cooperating rod 16, causes the connecting plate 17 to drive the inner rod 20, the outer rod 21, and the outer limiting plate 13 to rotate. After rotation, the limiting plate 13 is locked at the bottom of the limiting plate 22. Even if the motor 6 is damaged, the moving seat 23 will abut against the limiting plate 22, and the main body 3 of the roller shutter will not fall directly due to gravity, thus protecting the user.

[0038] Example 2:

[0039] A rolling shutter door electric drive system, such as Figure 1-8As shown, in order to lock the handle 27, this embodiment makes the following additions based on embodiment 1: The locking assembly includes a movable frame 29 and a mounting plate 32. The mounting plate 32 is welded to the outer side wall of the roller shutter body 3. A push rod 31 is rotatably connected to the outer side wall of the mounting plate 32. The movable frame 29 is slidably connected to the inner wall of the outer frame 28. A locking rod 26 is welded to the outer side wall of the movable frame 29. The locking rod 26 is slidably connected to the inner wall of the handle 27. A spring 30 is welded between the movable frame 29 and the inner wall of the outer frame 28.

[0040] Working principle: When the main body 3 of the roller shutter door moves upward, the push rod 31 presses the moving frame 29, causing the moving frame 29 to compress the spring 30. The movement of the moving frame 29 causes the locking rod 26 to disengage from the locking of the handle 27, at which point the handle 27 can be rotated. When the main body 3 of the roller shutter door moves downward, the handle 27 is reversed and then the locking rod 26 locks the handle 27 to prevent accidental damage.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
