Description

Technical Field

[0001] This utility model relates to the technical field of opening and closing control devices, specifically to a single or double independent opening and closing control device for curtains. Background Technology

[0002] Currently, most electric curtain control systems on the market use synchronous belts or chains to achieve synchronized opening and closing of curtains on both sides. Their transmission structure typically rigidly connects both sides of the curtains to the transmission belt via fixed connectors. This traditional structure has significant limitations. Because traditional mechanisms lack reliable clutch designs, it's difficult to achieve intelligent separation control of the transmission and moving parts. The curtain opening and closing action is limited to synchronized operation on both sides, making it impossible to independently control the opening degree of one side of the curtain according to usage needs. Especially in applications requiring ventilation or light adjustment on one side of the curtain, the traditional structure lacks operational flexibility, and its complex mechanical structure leads to high maintenance costs. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The purpose of this invention is to provide a curtain single or double independent opening and closing control device to solve the problem that the existing technology cannot achieve independent control on one side.

[0005] II. Technical Solution

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a curtain single / double independent opening and closing control device, including a left slide rail and a right slide rail arranged opposite each other, and a slide block that can slide within the slide rail formed on the opposite sides of the left and right slide rails. A belt driven by a motor is provided above the left and right slide rails, and the slide blocks are respectively connected to the opposite ends of the belt. When the belt rotates, it drives the two slide blocks to move in opposite directions to move closer or further apart. Sliding grooves for sliding hooks are also provided on the opposite sides of the left and right slide rails. A lever for moving the hooks along the sliding grooves is fixedly connected below the slide block. The slide block includes a positioning block, a movable block, and a magnetic suction assembly. The positioning block is slidably connected within the slide rail formed on the opposite sides of the left and right slide rails. The magnetic suction assembly controls the movable block to attract and separate from the positioning block. When the movable block and the positioning block are attracted, the belt is clamped between the movable block and the positioning block so that the slide block moves synchronously with the belt.

[0008] Furthermore, the left and right slide rails are provided with sliding protrusions on opposite sides. The positioning block includes a base block and a vertical plate fixedly connected to the base block. Sliding grooves are respectively opened on both sides of the base block, and the sliding protrusions are embedded in the sliding grooves. The magnetic attraction assembly includes an electromagnet fixedly connected to the top of the vertical plate and an iron plate fixedly connected to the top of the positioning block. When the electromagnet is energized, the iron plate is attracted to the surface of the electromagnet.

[0009] Furthermore, a guide rod is fixedly connected to the surface of the longitudinal plate, and a guide hole is opened on the surface of the movable block. The guide rod is slidably connected to the guide hole, and a compression spring is sleeved on the guide rod. The two ends of the compression spring are fixedly connected to the longitudinal plate and the movable block, respectively. When the electromagnet is de-energized, the movable block is pushed away from the longitudinal plate by the compression spring, and a gap is formed between the longitudinal plate and the movable block for the belt to pass through.

[0010] Furthermore, the inner wall of the belt is provided with several grooves, and the movable block is provided with a protrusion on the side opposite to the longitudinal plate that can be fitted into the groove, and there are at least two protrusions.

[0011] Furthermore, the upper end of the movable block is bent towards the longitudinal direction to form a horizontal plate, and the iron sheet is embedded in the end face of the horizontal plate.

[0012] Furthermore, a back plate is fixedly connected to one side of the left and right slide rails near the sliding block's moving area, and the longitudinal plate is arranged parallel to the back plate with a small gap.

[0013] III. Beneficial Effects

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention employs an electromagnetically controlled magnetic suction assembly in conjunction with a spring-loaded reset mechanism to achieve independent control of the curtain's single and double-sided opening and closing. This ensures rapid and reliable connection and separation between the slide and the drive belt, significantly improving system control accuracy and response speed. The interlocking structure of the convex and groove joints, combined with backplate support, effectively enhances the connection stability between the drive belt and the slide, preventing slippage or misalignment during operation.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please refer to the following: A curtain single- or double-sided independent opening and closing control device. Figure 1 The system includes a left slide rail 1 and a right slide rail 2 arranged opposite to each other, and slide blocks 3 that can slide within the tracks formed on opposite sides of the left and right slide rails 1 and 2. A belt 4 is installed above the left and right slide rails 1 and 2, and the belt 4 is driven to rotate by a pulley driven by a motor. Slide blocks 3 are connected to the two ends of the opposite sides of the belt 4. When the belt 4 rotates, it drives the two slide blocks 3 to move in opposite directions to move closer or further apart. Specifically, sliding grooves 5 are also provided on the opposite sides of the left and right slide rails 1 and 2 to allow the hooks to slide. A lever 6 is fixedly connected below the slide blocks 3 to move the hooks along the sliding grooves 5. When the curtain is closed, the two slide blocks 3 are located in the middle of the opposite sides of the belt 4. When the curtain is opened, the belt 4 drives the slide blocks 3 to move, and the slide blocks 3 on the opposite sides move towards the two ends of the belt 4, thereby moving the hooks and opening the curtain.

[0023] Among them, the two slide blocks 3 are set to be independently connected to the belt 4. Specifically, the slide block 3 includes a positioning block 31, a movable block 32 and a magnetic suction component 33. The positioning block 31 is slidably connected in the slide rail formed on the opposite side of the left slide rail 1 and the right slide rail 2. The magnetic suction component 33 controls the movable block 32 to be attracted and separated from the positioning block 31. When the movable block 32 is attracted to the positioning block 31, the belt 4 is clamped between the movable block 32 and the positioning block 31 so that the slide block 3 moves synchronously with the belt 4.

[0024] The left slide rail 1 and the right slide rail 2 are provided with sliding protrusions 7 on opposite sides. The positioning block 31 includes a bottom block 311 and a vertical plate 312 fixedly connected to the bottom block 311. Sliding grooves 3111 are respectively opened on both sides of the bottom block 311. The sliding protrusions 7 are embedded in the sliding grooves 3111, thereby restricting the positioning block 31 to slide only along the length direction of the sliding grooves 3111. The magnetic attraction component 33 includes an electromagnet 331 fixedly connected to the top of the vertical plate 312 and an iron plate 332 fixedly connected to the top of the positioning block 31. Specifically, the upper end of the movable block 32 is bent towards the vertical plate 312 to form a horizontal plate 323, and the iron plate 332 is embedded in the end face of the horizontal plate 323. When the electromagnet 331 is energized, the iron plate 332 is attracted to the electromagnet 331. The iron plate 332 drives the movable block 32 to move closer to the positioning block 31 and clamps the belt 4 in the middle.

[0025] A guide rod 313 is fixedly connected to the surface of the longitudinal plate 312. A guide hole 321 is opened on the surface of the movable block 32. The guide rod 313 is slidably connected to the guide hole 321. A compression spring 34 is sleeved on the guide rod 313. The two ends of the compression spring 34 are fixedly connected to the longitudinal plate 312 and the movable block 32, respectively. When the electromagnet 331 is de-energized, the movable block 32 is pushed away from the longitudinal plate 312 by the compression spring 34, forming a gap between the longitudinal plate 312 and the movable block 32 for the belt 4 to pass through, thereby separating the movable block 32 from the positioning block 31. In this state, the separated slide 3 does not move with the belt 4. By controlling the connection and separation of the two slides 3 from the belt 4, the opening and closing of the curtains on one or both sides can be independently controlled. The synergistic effect of the guide rod 313 and the compression spring 34 ensures the smooth separation of the movable block 32 from the positioning block 31, greatly reducing mechanical wear.

[0026] In addition, the inner wall of the belt 4 is provided with several grooves 41, and the movable block 32 is provided with a protrusion 322 that can fit into the groove 41 on the side opposite to the longitudinal plate 312. There are at least two protrusions 322. The cooperation between the protrusions 322 and the grooves 41 increases the stability of the connection between the belt 4 and the movable block 32, and prevents slippage or misalignment during operation.

[0027] In addition, a back plate 8 is fixedly connected to the side of the left slide rail 1 and the right slide rail 2 near the movable position of the slide block 3. The longitudinal plate 312 is set parallel to the back plate 8 with a small gap of 1-2mm. The back plate 8 provides support for the longitudinal plate 312 to ensure the stability of the movable block 32 when it is engaged with the positioning block 31.

[0028] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
