Description

Technical Field

[0001] The utility model relates to the technical field of electric curtains, and particularly relates to an electric sunshade curtain. Background Art

[0002] According to the needs of sun protection and privacy protection, modern buildings often install curtains inside the curtain wall. An electric curtain is a curtain device controlled by a motor drive, and the curtain fabric is driven by the motor to be retracted and unfolded to achieve the purpose of sunshading.

[0003] When installing an electric curtain on a curtain wall, the shape and structure of the curtain wall generally need to be considered. Sometimes, there are cases of a space-curved curtain wall or an irregularly shaped curtain wall. In the prior art, due to the irregular shape of the curtain wall, the upper part and the lower part of the window frame are not in the same vertical plane, and using traditional sunshade products cannot meet the sunshading requirements, or occupy too much indoor space, resulting in an unsatisfactory sunshading effect. Content of the Utility Model

[0004] The technical problem solved by the utility model is to provide an electric sunshade curtain that can be installed on a space-curved curtain wall or an irregularly shaped curtain wall, can meet the sunshading requirements, and can fit on the curtain wall to save indoor installation space.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An electric sunshade curtain includes two guide rails arranged oppositely up and down, a fixed rod fixedly arranged on the two guide rails, a traction rod slidably arranged between the two guide rails, a folding curtain cloth connected between the fixed rod and the traction rod, and a driving assembly for driving the traction rod to slide on the guide rail. Transmission blocks are respectively arranged at positions corresponding to both ends of the traction rod on the guide rail. The traction rod is a telescopic rod, and universal connectors connected to the transmission blocks are arranged at both ends of the traction rod.

[0007] In a specific embodiment of the utility model, the universal connector includes a fixing piece, an intermediate connecting piece and a connecting block. The fixing piece is fixed on the traction rod, the intermediate connecting piece is rotatably connected to the fixing piece, the connecting block is rotatably connected to the intermediate connecting piece, the rotation directions of the intermediate connecting piece and the connecting block are perpendicular to each other, and the connecting block is connected to the transmission block.

[0008] In the above-described technical solution, on a space-curved curtain wall or an irregularly shaped curtain wall, the guide rails are generally arranged up and down along the curtain wall. Therefore, there may be situations where the upper and lower guide rails are not parallel, or the guide rails are bent or inclined. The utility model adjusts the postures of the traction rod and the driven rod through the universal connectors at both ends of the traction rod and the driven rod on the guide rail, so that the curtain cloth of the electric curtain can fit the inner surface of the curtain wall as much as possible to meet the sunshading requirements of the curtain, and at the same time, the indoor space occupied by the electric curtain can be reduced.

[0009] Moreover, the traction rod connecting the upper and lower ends of the window frame is connected to the guide rail through a universal joint, and the traction rod is a telescopic rod. Therefore, during the movement of the curtain, the angle and length of the traction rod can change according to the attitude changes of the upper and lower guide rails. Even if the upper and lower guide rails are not parallel, the track is inclined or bent, the traction rod will not be stuck by the guide rail, ensuring the smooth opening and closing of the curtain.

[0010] In a specific embodiment of the present utility model, at least one driven rod for driving the folding curtain cloth is provided between the fixed rod and the traction rod. The driven rod is a telescopic rod, and sliders are also respectively provided at positions corresponding to both ends of the driven rod on the guide rail. Universal joints for connecting with the sliders are provided at both ends of the driven rod.

[0011] In a specific embodiment of the present utility model, the folding curtain cloth includes several honeycomb curtains. One end of the honeycomb curtain is fixed to the fixed rod or the driven rod, and the other end of the honeycomb curtain is fixed to the traction rod or the driven rod.

[0012] In a specific embodiment of the present utility model, it further includes a curtain box for covering the guide rail, the ends of the fixed rod, the ends of the traction rod, the ends of the driven rod, and the upper and lower edges of the folding curtain cloth.

[0013] In a specific embodiment of the present utility model, the telescopic rod includes a left rod body and a right rod body arranged oppositely. A chute and a sliding foot that cooperate with each other to enable the left rod body and the right rod body to slide relative to each other are respectively provided on the left rod body and the right rod body.

[0025] Next, embodiments of the technical solutions of the present utility model will be described in detail with reference to the accompanying drawings.

[0026] See Figures 1 to 4 , the electric sun - shading curtain of the present utility model includes a guide rail 100, a drive assembly 300, a fixed rod 400, a traction rod 600, a driven rod 500, a fixed - distance rope 700, and a folding curtain cloth 800.

[0027] The guide rail 100 is hollow inside and has a rail groove 101 on its surface. There are two guide rails 100, which are divided into an upper guide rail 100a provided above and a lower guide rail 100b located below. In the present utility model, one drive assembly 300 is provided on each of the upper guide rail 100a and the lower guide rail 100b.

[0028] Each drive assembly 300 includes a transmission belt, a drive motor 301, and a transmission box 302. The transmission belt is arranged inside the guide rail 100. There are two transmission boxes 302, which are respectively arranged at both ends of the guide rail 100. Inside the transmission box 302, pulleys for driving the transmission belt are arranged. The drive motor 301 is in transmission connection with the pulley in one of the transmission boxes 302.

[0029] The fixed rod 400 is arranged at one end far from the driving motor. Both ends of the fixed rod are respectively fixed on the upper guide rail 100a and the lower guide rail 100b through hinges. Since the fixed rod 400 does not slide on the guide rail, the angle of the hinge can be adjusted and fixed according to the positions of the upper and lower rails. The fixed rod 400 is used to fix one end of the folding curtain 800.

[0030] The traction rod 600, the driven rod 500, and the folding curtain 800 are all located between the upper guide rail 100a and the lower guide rail 100b.

[0031] When the upper guide rail 100a and the lower guide rail 100b are relatively short, only one section of the folding curtain 800 is needed, so only the fixed rod 400 and the traction rod 600 need to be provided. When the upper guide rail 100a and the lower guide rail 100b are relatively long, two or more sections of the folding curtain are needed, so one or more driven rods need to be provided between the fixed rod 400 and the traction rod 600.

[0032] Combined Figure 3 and Figure 4 As shown in the figure, transmission blocks 110 that slide on the guide rail 100 are provided at the positions corresponding to both ends of the traction rod 600 on the upper guide rail 100a and the lower guide rail 100b. The transmission block 110 passes through the rail groove 101 of the guide rail and is fixedly connected to the transmission belt. Sliders 120 that slide on the guide rail 100 are provided at the positions corresponding to both ends of the driven rod 500 on the upper guide rail 100a and the lower guide rail 100b, but the sliders are not fixedly connected to the transmission belt.

[0033] Both ends of the traction rod 600 are connected to the transmission block 110 through universal connectors 510. Both ends of the driven rod 500 are also connected to the slider 120 through universal connectors 510.

[0034] According to Figure 5 As shown in the figure, both the traction rod 600 and the driven rod 500 are telescopic rods, including a left rod body 610 and a right rod body 620 arranged oppositely. The left rod body 610 and the right rod body 620 have the same structure, and both include an outer rod 620a and an inner rod 620b. The inner rod 620b is inserted into the outer rod 620a and fixed together by an interference fit. One side edge of the inner rod 620b has a chute 621, and the other side has a sliding foot 622. In the present utility model, the sliding foot of the left rod body is inserted into the slide rail of the right rod body, and the sliding foot of the right rod body is inserted into the slide rail of the left rod body, so that the left rod body 610 and the right rod body 620 can slide relative to each other, thereby realizing the telescopic function. A universal connector is respectively connected to the upper end of the left rod body 610 and the lower end of the right rod body 620.

[0035] The surface of the outer rod 620b is also provided with a bayonet 623, and clamping plates are fixedly connected to both ends of the folding curtain. By clamping the clamping plates in the bayonets of the outer rod, the connection between the folding curtain and the traction rod and the driven rod is realized.

[0036] Refer to Figure 3 , the universal joint 510 includes a fixing member 511, an intermediate connecting member 512, and a connecting block 513 that are connected in sequence. Among them, the fixing member 511 is connected to the inner rod 620b of the traction rod 600 or the driven rod 500. The intermediate connecting member 512 is rotatably connected to the fixing member 511. The connecting block 513 is rotatably connected to the intermediate connecting member 512. The rotation directions of the intermediate connecting member 512 and the connecting block 513 are perpendicular to each other.

[0037] Specifically, one end of the fixing member 511 is fixed to the inner rod 620b, and the other end has a longitudinally arranged notch. First shaft holes 514 are provided on both sides of the notch of the fixing member 511. A first rotating shaft that connects the fixing member 511 and the intermediate connecting member 512 is arranged in the first shaft holes 514. The intermediate connecting member 512 can rotate in the X-axis direction within the notch of the fixing member 511. A transversely arranged notch is provided on the connecting block 513. Second shaft holes 515 are provided on both sides of the notch of the connecting block 513. A second rotating shaft that connects the intermediate connecting member 512 and the connecting block 513 is arranged in the second shaft holes 515. The intermediate connecting member 512 can rotate in the Y-axis direction within the notch of the connecting block 513. With the cooperation of the fixing member 511, the intermediate connecting member 512, and the connecting block 513, the universal joint 510 realizes the function of being able to rotate in all directions of front, back, left, and right.

[0038] The connecting block 513 is used to connect with the transmission block or the slider. In this embodiment, as Figure 3 shown, the connecting block 513 of the universal joint 510 on the traction rod is bolted to the transmission block 110, and a clamping groove 200 that is stuck on the edge of the sliding groove 101 of the guide rail 100 is formed at the joint of the two, realizing the ability to slide on the guide rail 100. In this embodiment, as Figure 4 shown, the connecting block 513 of the universal joint 510 on the driven rod 500 is integrally formed with the slider 120, and also has a clamping groove 200 that is stuck on the edge of the sliding groove 101 of the guide rail 100.

[0039] Since both ends of the traction rod 600 and the driven rod 500 are connected to the transmission block 110 or the slider 120 on the guide rail 100 by using the universal joint 510, and both the traction rod and the driven rod are telescopic rods, therefore, even if the upper and lower guide rails are not parallel, or the guide rail has conditions such as bending and inclination, the universal joint can adaptively adjust the postures of the traction rod and the driven rod, avoid jamming of the traction rod and the driven rod, and ensure that the curtain can be smoothly opened and closed.

[0040] The fixed-distance rope 700 passes through each folded curtain fabric and is connected between adjacent rods (the fixed rod, the traction rod, and the driven rod are collectively referred to as rods). The fixed-distance rope 700 functions to control the set length by which each folded curtain fabric is pulled open. In the present utility model, two fixed-distance ropes 700 are respectively threaded through each folded curtain fabric 800 from top to bottom. The lengths of each fixed-distance rope are equal.

[0041] See Figure 6 , in this embodiment, the folded curtain fabric 800 is a bellows curtain, and the bellows curtain is composed of a plurality of successively connected honeycomb structures. The honeycomb structure includes two oppositely arranged short sides 801 and four long sides 802 connected to each other on both sides of the short sides. Adjacent honeycomb structures share a short side 801. In the natural state, the honeycomb structure is in a compressed state. When the curtain needs to be opened, the honeycomb structure is stretched and unfolded from the compressed state under the drive of the traction rod or the driven rod.

[0042] Since there are gaps between the upper edge of the folded curtain fabric 800 and the upper track, and between the lower edge and the lower track. To ensure aesthetics, curtain boxes are respectively provided at the upper and lower ends of the window frame to cover the guide rails, the ends of the fixed rod, the ends of the traction rod, the ends of the driven rod, and the upper and lower edges of the folded curtain fabric.

[0043] The above is the electric sunshade curtain of the present utility model. This electric sunshade curtain takes into account the situations where the guide rails above and below the space curved surface curtain wall or the curtain wall with irregular shape are not parallel, bent, or inclined. The attitudes of the traction rod and the driven rod are adjusted through the universal joints at both ends of the traction rod and the driven rod on the guide rail, so that the electric curtain can meet the sunshade requirements. Moreover, since the guide rail can be arranged along the space curved surface curtain wall or the curtain wall with irregular shape, the curtain fabric of the electric curtain can be closer to the inner surface of the curtain wall, thereby reducing the indoor space occupied by the electric curtain.

[0044] The present utility model drives the traction rod 600 through the drive assembly 300 and drives the driven rod 500 to slide on the upper and lower tracks 100a, 100b, and then drives the folded curtain fabric 800 to be folded and retracted or stretched and unfolded to realize the opening and closing of the curtain. Since both ends of the traction rod 600 and the driven rod 500 are connected to the transmission block 110 or the slider 120 on the guide rail 100 by means of universal joints 510, and both the traction rod 600 and the driven rod 500 are telescopic rods, therefore, even if the upper and lower guide rails on the window are not parallel, or the guide rail is bent, inclined, etc., the universal joint can adaptively adjust the attitudes of the traction rod and the driven rod, avoiding the traction rod and the driven rod being stuck by the guide rail, and ensuring that the curtain can be opened and closed smoothly.
