Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] like Figures 1-6 As shown, this utility model provides a technical solution: an electric windproof roller blind, including a storage compartment 1, a lifting assembly inside the storage compartment 1, a roller blind 2 on one side of the lifting assembly, the bottom end of the roller blind 2 penetrating the bottom of the storage compartment 1, and an end seal 3 connected to the bottom end of the roller blind 2 outside the storage compartment 1; vertically downward first limiting rods 5 are provided on opposite sides of the storage compartment 1, the bottom ends of the two first limiting rods 5 penetrating the bottom of the end seal 3 to prevent the end seal 3 from moving away from or towards the window during vertical movement; two support mechanisms are also provided on the top of the end seal 3, and one side of the two support mechanisms contacts the side of the roller blind 2 away from the window to prevent airflow from blowing the middle of the roller blind 2 away from the window.

[0031] In use, the top of the end seal 3 is provided with two circular holes, and three ball bearings are embedded in the inner wall of the circular holes in a circular distribution. They are slidably connected to the groove. The side of the ball bearings away from the circular holes is slidably connected to the outer wall of the first limiting rod 5, reducing the friction between the end seal 3 and the first limiting rod 5. The lifting assembly includes at least a first motor, which is installed on the side of the storage compartment 1 and has a winding roller connected to its output end. The surface of the winding roller is fixedly connected to one end of the top of the roller blind 2. During rotation, it drives the top of the roller blind 2 to rotate, thereby winding and rolling up the roller blind 2. The roller blind 2 is raised and lowered by changing the direction of rotation. The bottom of the storage compartment 1 is provided with a first sliding groove, through which the roller blind 2 extends to the outside and connects to the end seal 3.

[0032] The support mechanism includes a second connecting part 7 fixedly sleeved on the outside of the first limiting rod 5. A telescopic first support rod 8 is hinged to the bottom of the second connecting part 7. A positioning cylinder 9 is rotatably connected to the end of the first support rod 8 away from the second connecting part 7. A telescopic second support rod 10 is rotatably connected to the outside of the positioning cylinder 9. A first connecting part 4 is hinged to the end of the second support rod 10 away from the positioning cylinder 9. The bottom of the first connecting part 4 is fixedly connected to the top of the end seal 3. A traction component is provided at the end of the positioning cylinder 9 away from the roller blind 2. The traction component is used to drive the connection between the telescopic first support rod 8 and the second support rod 10 toward the middle of the roller blind 2, so that the first support rod 8 and the second support rod 10 extend to form a triangle, supporting the roller blind 2 on the side away from the window.

[0033] In use, the roller blind 2 is rolled up or released via the lifting assembly. When the roller blind 2 is unfolded, it is released, and under the action of gravity, the end seal 3 slides downward along the first limiting rod 5. At this time, the first connecting part 4 moves downward with the end seal 3, while the first support rod 8 and the second support rod 10 gradually extend and open. Then, when the end seal 3 is lowered to an appropriate height, that is, after the roller blind 2 is unfolded to the specified size, if a large airflow enters the room causing the roller blind 2 to sway and it is necessary to restrain the roller blind 2, the traction assembly is controlled to work, causing the traction assembly to drive the bottom end of the first support rod 8 and the top end of the second support rod 10 towards the center, forming a triangle with the vertically downward first limiting rod 5. The first support rod 8 and the second support rod 10 support the roller blind 2 on the side away from the window, preventing the airflow entering along the window from blowing the roller blind 2. At the same time, when the roller blind 2 is in the middle of movement, one vertex of the two triangles contacts each other, so that the two first support rods 8 and the two second support rods 10 together form an X-shape, improving the support effect of the roller blind 2. When the roller blind 2 is rolled up, the traction component is first controlled to drive the connection between the first support rod 8 and the second support rod 10 to move towards both sides of the roller blind 2 and move to near the first limit rod 5. Then, the roller blind 2 is driven to roll up, causing the end seal 3 to rise. The bottom of the storage compartment 1 is provided with a lip plate to cover the end seal 3 and the part of the roller blind 2 near the bottom.

[0034] The positioning cylinder 9, the first support rod 8, and the second support rod 10 are all equipped with rubber pads on the side facing the roller blind 2. The rubber pads are in contact with the side of the roller blind 2 away from the window. The contact between the rubber pads and the roller blind 2 serves to protect the roller blind 2.

[0035] The storage compartment 1 has a first outer shell 6 on each side. The top of the inside of the first outer shell 6 is fixedly connected to the top of the first limiting rod 5. The bottom of the first outer shell 6 is fixedly connected to the second outer shell 16. The bottom of the inside of the second outer shell 16 is fixedly connected to the bottom of the first limiting rod 5. In use, the end seal 3 and the edge of the roller shutter 2 slide up and down on the inside of the second outer shell 16, which protects the edges and improves the stability of the first limiting rod 5.

[0036] The storage compartment 1 has a second sliding groove 17 at its bottom, and openings are provided on both sides of the storage compartment 1. The storage compartment 1 is connected to the interior of the first outer shell 6 through the openings. The traction component includes a horizontal traction structure and a vertical traction structure. The middle part of the horizontal traction structure is located inside the storage compartment 1, and the two sides of the horizontal traction structure are respectively connected to the interior of the corresponding first outer shell 6 through the openings. The middle part of the horizontal traction structure is connected to the vertical traction structure, and the bottom of the vertical traction structure passes through the second sliding groove 17. The bottom of the vertical traction structure is connected to the positioning cylinder 9. In use, the positioning cylinder 9 at the connection between the vertical traction structure and the first support rod 8 and the second support rod 10 is connected, thereby driving the connection to move up and down. The horizontal traction structure drives the vertical traction structure and the connection to move horizontally, thereby adjusting the position of the connection in the middle of the roller shutter 2, and adjusting the position of the first support rod 8 and the second support rod 10 according to actual needs.

[0037] The horizontal traction structure includes a second limiting rod 14, with both ends of the second limiting rod 14 fixedly connected to the inner walls of the corresponding first outer shell 6. Two movable plates 13 are slidably connected to the middle of the second limiting rod 14. The sides of the two movable plates 13 away from the second limiting rod 14 are threadedly connected to the outer sides of the corresponding threaded rods 15. Both ends of the two threaded rods 15 that are far apart from each other are connected to a drive structure for driving the corresponding threaded rods 15 to rotate. The ends of the two threaded rods 15 that are close to each other are rotatably connected by a rotating shaft to improve the stability of the rotating ends of the threaded rods 15. In use, the stability of the threaded rods 15 can be further enhanced by a bracket. The drive structure adopts a second motor, which drives the threaded rods 15 to rotate. Under the restriction of the second limiting rod 14, the movable plates 13 on the threaded rods 15 move horizontally along the axis of the threaded rods 15, thereby providing horizontal traction force.

[0038] The vertical traction structure includes a drive assembly 12. The top of the drive assembly 12 is fixedly connected to the bottom of the movable plate 13. The bottom end of the drive assembly 12 passes through the second slide groove 17. The bottom end of the drive assembly 12 is also connected to a third connecting part 11. One side of the third connecting part 11 is fixedly connected to the positioning cylinder 9 so that the positioning cylinder 9 can be driven to move up and down by the drive assembly 12. In use, the drive assembly 12 adopts an electric telescopic push rod. The extension and retraction of the electric telescopic push rod drives the positioning cylinder 9 to move up and down. At the same time, under the movement of the movable plate 13, the positioning cylinder 9 is further driven to move horizontally, adjusting the position of the positioning cylinder 9, the first support rod 8 and the second support rod 10 on the roller shutter 2.

[0039] Both the first support rod 8 and the second support rod 10 include several telescopic cylinders, which are arranged in a sequence from the positioning cylinder 9 away from it, namely the first telescopic cylinder, the second telescopic cylinder, and the third telescopic cylinder, and so on. The outer side of the first telescopic cylinder is slidably connected to the inner wall of the second telescopic cylinder, the outer side of the second telescopic cylinder is slidably connected to the third telescopic cylinder, and so on. The first telescopic cylinders on the first support rod 8 and the second support rod 10 are rotatably connected to the outer side of the positioning cylinder 9.
