[0032] The following is combined with Figure 1-9 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0033] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0034] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0035] like Figure 1-4 As shown, a vertical curtain comprises: a guide rail body 1 and a dimming rod 2 located in the guide rail body 1. The length of the guide rail body 1 in this embodiment is more than two meters. Of course, it can also be less than two meters in other embodiments, which will not be described in detail herein; an opening 11 is provided at the lower end of the guide rail body 1, and the guide rail body 1 is provided with a stopper 12 and a sliding member 3. The sliding member 3 has a certain elasticity. The sliding member 3 is connected to the guide rail body 1 and can move relative to the guide rail body 1. Specifically, the sliding member 3 can reciprocate between the end of the guide rail body 1 and the stopper 12 along the dimming rod 2 in the horizontal direction. When the sliding member 3 cooperates with the stopper 12, the sliding member 3 stops moving.

[0036] The sliding member 3 is connected to the outside of the guide rail body 1 ; or the sliding member 3 may be limited inside the guide rail body 1 and connected to the guide rail body 1 . In the present embodiment, the sliding member 3 is limited inside the guide rail body 1 .

[0037] like Figure 3As shown, the guide rail body 1 includes an upper portion 16 and a lower portion 17 , and the sliding member 3 abuts against the upper portion 16 and / or the lower portion 17 .

[0038] like Figure 1 As shown, a transmission mechanism 8 is provided at one end of the guide rail body 1, and the transmission mechanism 8 includes a motor assembly 81 and a transmission assembly 82. The transmission mechanism 8 is a utility model patent with a reference application number of 202223326036.8, that is, the opening and closing of the curtains and the turning of the leaves (that is, the light transmittance of the curtains) are controlled by a motor, which will not be described in detail here.

[0039] like Figure 1 , Figure 2 and Figure 5 As shown, the sliding member 3 is provided with a first abutting portion 33 matched with the stop portion 12; in this embodiment, the stop portion 12 is located in the middle of the guide rail body 1, and the stop portion 12 is a through hole.

[0040] The sliding member 3 includes a sliding portion 31 and a first abutting portion 33 arranged at one end of the sliding portion 31. The mounting portion 32 is connected to the sliding portion 31, specifically connected to the bottom of the sliding portion 31; the top of the first abutting portion 33 is inclined and recessed, specifically, the first abutting portion 33 is inclined in the opposite direction of the transmission mechanism 8. By utilizing the elasticity of the first abutting portion 33 and tilting the top of the first abutting portion 33, when the electric curtain needs to be closed, the first abutting portion 33 can be easily detached from the stop portion 12.

[0041] The end of the sliding portion 31 is provided with an extension portion 311 and a support portion 312 connected to the extension portion 311 on both sides, the first abutting portion 33 is provided between the two extension portions 311, and there is a gap between the first abutting portion 33 and the extension portion 311. By tilting the first abutting portion 33, it is convenient for the first abutting portion 33 to disengage from the stop portion 12 when the electric curtain is closed; when the sliding member 3 moves toward the transmission mechanism 8, when the inclined portion of the top of the first abutting portion 33 is located in the stop portion 12, the sliding member 3 will no longer slide, and a pulling force is exerted on the dimming rod 2 to prevent the dimming rod 2 from being exposed outside the guide rail body 1. The user does not need to push the dimming rod 2 back into the guide rail body 1 every time the dimming rod 2 is exposed, thereby improving the user experience; it can also effectively prevent the dimming rod 2 from being damaged, further extending the service life of the dimming rod 2.

[0042] like Figure 6As shown, in order to avoid the defect of insufficient elasticity of the first abutting portion 33 when the sliding member 3 is used for a long time, in a preferred embodiment, a receiving portion 34 is provided on the sliding portion 33, and the receiving portion 34 extends to the first abutting portion 33, and an elastic member 341 is provided in the receiving portion 34 to abut against the first abutting portion 33 (the elastic member 341 is a spring steel wire), so that the first abutting portion 33 always maintains good elasticity; in order to fix the elastic member 341 in the receiving portion 34, in this embodiment, the receiving portion 34 is provided with a fixing portion 342, and the elastic member 341 and the fixing portion 342 are combined.

[0043] Of course, in other embodiments, other methods may be used to prevent the dimming rod 2 from being exposed outside the guide rail body 1, such as Fig. 9 As shown, a baffle is provided in the guide rail body 1 (the stop portion 12 is a baffle), and the sliding member 3 can abut against the stop portion 12. When the sliding member 3 slides to the baffle, it will be blocked by the baffle and cannot move, thereby achieving the effect that the sliding member 3 will not move when the above-mentioned first abutting portion 33 is located in the stop portion 12.

[0044] like Figure 8 As shown, the guide rail body 1 is provided with a plurality of pulley assemblies 5 , the pulley assembly 5 includes a pulley body 51 and a dimming hanger 52 , and the pulley body 51 is provided with an insertion hole 511 connected to the dimming rod 2 .

[0045] like Figure 4 As shown, limit members 7 are provided on both sides of the guide rail body 1. The limit members 7 are arranged at the opening 11. A limit opening 71 is formed between the two limit members 7. The width of the limit opening 71 is less than or equal to the width of the dimming rod 2, which can further prevent the dimming rod 2 from being exposed from the opening 11.

[0046] like Figure 1 and Figure 4 As shown, the sliding member 3 is connected to the dimming rod 2; in the present embodiment, an indirect connection is adopted, that is, the mounting portion 32 is provided with a ball frame 4, the ball frame 4 is connected to the dimming rod 2, and the ball frame 4 is against the guide rail body 1 or the limit member 7, the sliding member 3 is partially located at the upper part 16, and the ball frame 4 is located at the lower part 17; specifically, the ball frame 4 is against the limit member 7, the sliding portion 31 is located at the upper part 16, the upper part 16 provides a certain supporting force for the sliding portion 31, the mounting portion 32 and the ball frame 4 are located at the lower part 17, the sliding member 3 is arranged on the limit member 71 through the ball frame 4, so that the limit member 71 also provides a certain supporting force for the sliding member 3, and the ball frame 4 is consistent with the structure of the pulley body 51, which is not described in detail here; in other embodiments, the sliding member 3 and the dimming rod 2 can be directly connected, that is, the mounting portion 32 is connected to the dimming rod 2, and is against the guide rail body 1 or the limit member 7 (specifically against the limit member 7).

[0047] like Figure 4 and Figure 7As shown, a frame 6 is provided inside the guide rail body 1, and one end of the frame 6 can be connected to the sliding member 3 to drive the sliding member 3 to move. Specifically, the frame 6 is provided with a second abutting portion 61 outwardly, and the second abutting portion 61 abuts against the first abutting portion 33 to drive the sliding member 3 to move, and cooperates with the upper support portion 312 to support the second abutting portion 61, so that the first abutting portion 33 and the second abutting portion 61 are more closely fitted, so as to better pull the sliding member 3 to move; the frame 6 is assembled with the pulley body 51.

[0048] like Figure 4 As shown, a transmission belt 13 is provided in the guide rail body 1, and the frame 6 is connected to the transmission belt 13. Specifically, a plurality of sliders 14 are provided on the transmission belt 13, and the frame 6 and the sliders 14 are connected by a connecting piece 15 so that the transmission belt 13 drives the frame 6 to move through the sliders 14.

[0049] Principle description:

[0050] The electric curtain is in the open state: the transmission mechanism 8 is started, and the top of the first abutting portion 33 presses against the guide rail body 1, so that the first abutting portion 33 is pressed downward, and the second abutting portion 61 of the frame 6 abuts against the first abutting portion 33 to pull the sliding member 3 to move, until the inclined portion of the top of the first abutting portion 33 is located at the stop portion 12 of the guide rail body 1, the first abutting portion 33 is not pressed by the guide rail body 1, the first abutting portion 33 bounces up, the second abutting portion 61 separates from the first abutting portion 33, and the entire sliding member 3 stays in the original position of the guide rail body 1, pulling the dimming rod 2, and the frame 6 continues to move forward, so that the electric curtain is opened.

[0051] The electric curtain is in the closed state: the frame 6 moves toward the sliding member 3, the second abutting portion 61 passes through the supporting portion 312 and is located below the first abutting portion 33, and the entire frame 6 pushes the sliding member 3 to move. Since the first abutting portion 33 in the direction in which the frame 6 pushes the sliding member 3 is inclined and will not be blocked by the stop portion 12, the inclined portion at the top of the first abutting portion 33 disengages from the stop portion 12, and due to the elasticity of the first abutting portion 33, the top of the first abutting portion 33 will continue to press against the guide rail body 1 to press the first abutting portion 33 downward, and the frame 6 continues to move forward to achieve the closing of the electric curtain.

[0052] The technical effects of this utility model are mainly reflected in the following aspects:

[0053] Preventing the dimming rod from being exposed from the opening improves the user experience and effectively prevents damage to the dimming rod, thereby extending the service life of the dimming rod.

[0054] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
