[0024] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0026] like Figure 1-3As shown, a curtain rail device includes a rail 1 and a first sliding assembly. The first sliding assembly 2 is arranged on the rail 1. The first sliding assembly 2 includes a slider 3, a plurality of hooks 4, an active rod 6, a driven rod 7 and a transmission member 8. The slider 3 and the plurality of hooks 4 are all slidably connected to the rail 1, and the plurality of hooks 4 are located between the slider 3 and the front end of the rail 1. The active rod 6 and the driven rod 7 are respectively slidably connected to both sides of the slider 3 and are arranged in the same direction as the rail 1. One end of the active rod 6 is connected to the hook away from the front end of the rail 1. 4 is connected, a first hanging portion 71 is provided on one side of the driven rod 7, and a transmission member 8 is provided on the slider 3. The active rod 6 can drive the driven rod 7 to slide synchronously in the opposite direction through the transmission member 8. Taking the unfolding of the curtain cloth as an example, when in use, the upper end of the curtain cloth is evenly hung on several hanging members 4, and one upper corner of the curtain cloth is fixed to the front end of the slide rail 1, and the other upper corner is hung on the first hanging portion 71. Under normal circumstances, the curtain is folded and retracted. At this time, the distance between the first hanging portion 71 and the hanging member 4 away from the front end of the slide rail 1 is close to or equal to the distance between them. The distance between any two adjacent hanging parts 4 is greater than 100%. The user can pull the curtain fabric away from the lower corner of one side of the front end of the slide rail to drive the slider 3 to slide along the slide rail 1, thereby linking a number of hanging parts 4 to slide and unfold through the curtain fabric. The distance between the slider 3 and the hanging part 4 away from the front end of the slide rail 1 gradually increases. When the curtain fabric gradually tends to be straightened in the horizontal direction, the hanging part 4 will pull the active rod 6 to slide, and then drive the driven rod 7 to slide in the opposite direction through the transmission part 8, so that the distance between the first hanging part 71 and the slider 3, the slider 3 and The spacing between the hanging parts 4 away from the front end of the slide rail 1 increases synchronously, so the side of the curtain cloth away from the front end of the slide rail 1 will unfold along with the first hanging part 71 to which it is hung, overlapping with the opposite curtain cloth in the middle of the window, or covering the driving component at the rear end of the slide rail 1. The same is true when the hanging parts 4 are retracted, thereby achieving the effect that the curtain cloth can be unfolded or retracted at all places, making the curtain cloth retracted more thoroughly, avoiding occupying the light-transmitting area of the window due to the fixed width of the curtain layout part, ensuring the lighting in the room, and improving the consistency of the appearance of the curtain cloth.
[0027] Furthermore, the curtain rail device also includes a driving gear 91, a driving member 92, a driven gear 93 and a gear belt 94. The driving gear 91 is rotatably connected to the front end of the slide rail 1. The driving member 92 is arranged at the front end of the slide rail 1 and can drive the driving gear 91 to rotate. The driven gear 93 is rotatably connected to the rear end of the slide rail 1. One end of the gear belt 94 is sleeved on the driving gear 91, and the other end of the gear belt 94 is sleeved on the driven gear 93. The driving gear 91 and the driven gear 93 are both engaged with the gear belt 94, and the slider 3 is partially connected to the gear belt 94.
[0028] In one embodiment, the slide 3 can be driven by a bead drawing head (not shown in the drawings).
[0029] In one embodiment, the slider 3 can be driven by a rack and a motor. The rack is slidably connected to the front end of the slide rail 1 in the same direction. The hanging member 4 away from the end of the slide rail 1 is fixedly connected to the rack. The output end of the motor is connected to the rack through a gear (not shown in the drawings), so that the output end of the motor can drive the rack to slide by rotating, thereby driving the hanging member 4 away from the end of the slide rail 1 to slide, so that the curtains hung on the hanging member 4 can be unfolded or folded.
[0030] Furthermore, the curtain slide rail 1 device also includes a second sliding component, the first sliding component 2 is arranged on the front half of the slide rail 1, and the second sliding component is arranged on the rear half of the slide rail 1. The second sliding component and the first sliding component 2 are centrally symmetrical with the midpoint of the slide rail 1 on the horizontal plane. Therefore, the adjacent sides of the two curtain fabrics will unfold and overlap with their respective first hanging parts 71, thereby ensuring the shading effect in the middle of the window.
[0031] Specifically, the driving member 92 is a motor, which is vertically arranged on the lower side wall of the front end of the slide rail 1 , and the output shaft of the motor is coaxially fixed to the driving gear 91 .
[0032] In this embodiment, the driving member 92 can drive the driving gear 91 to rotate, and the driving gear 91 can drive the gear belt 94 to roll. At this time, the driven gear 93 will rotate adaptively, thereby driving the two sliders 3 to slide synchronously in the opposite direction along the slide rail 1 through the gear belt 94, driving the two sets of hanging parts 4 to slide, expand and retract.
[0033] Furthermore, the transmission member 8 is a synchronous gear, which is rotatably connected to the slider 3 and is located between the active rod 6 and the driven rod 7. The inner sides of the active rod 6 and the driven rod 7 are provided with tooth grooves 61, and the two tooth grooves 61 are engaged with the synchronous gear. When the slider 3 drives several hanging members 4 to slide and unfold, as the curtain fabric gradually straightens, the hanging member 4 away from the end of the slide rail 1 will pull the corresponding active rod 6 to slide, thereby driving the driven rod 7 to slide in the opposite direction through the transmission of the tooth groove 61 and the synchronous gear, so that the part of the curtain hung on the first hanging part 71 is synchronously unfolded.
[0034] Furthermore, a claw 62 is provided in the horizontal direction at one end of the active rod 6 close to the hanging member 4. The direction of the claw 62 is perpendicular to the direction of the active rod 6. The claw 62 is clamped on the hanging member 4 away from the front end of the slide rail 1. When the slider 3 slides and changes the distance between it and the hanging member 4 away from the end of the slide rail 1, the hanging member 4 will drive the active rod 6 and the slider 3 to slide relative to each other through the claw 62.
[0035] Furthermore, an escape opening 31 is opened on the lower side wall of the slider 3 along its sliding direction, and the first hanging portion 71 is arranged on the lower side wall of the driven rod 7 and passes through the escape opening 31 to the bottom of the slider 3 so as to hang the curtain cloth. When the driven rod 7 slides, the first hanging portion 71 will slide in the escape opening 31.
[0036] Furthermore, a second hanging portion 32 is provided on the lower side wall of the slider 3, and the second hanging portion 32 is located between the first hanging portion 71 and the hanging part 4 away from the front end of the slide rail 1. The upper end of the curtain cloth can be hung on the second hanging portion 32. When the driven rod 7 slides, the part of the curtain cloth located between the first hanging portion 71 and the second hanging portion 32 and the part of the curtain cloth located between the second hanging portion 32 and the hanging part 4 away from the end of the slide rail 1 will be synchronously retracted or unfolded, so as to better control the width of a single movable cloth piece on the adjacent side of the curtain cloth, and further improve the consistency of the appearance of the curtain cloth.
[0037] Furthermore, the lower end of the hanging member 4, the first hanging portion 71 and the second hanging portion 32 are all hanging rings for the hook at the upper end of the curtain fabric to hang.
[0038] Furthermore, the first sliding assembly 2 also includes several elastic members 5, and the slider 3 and the hanging member 4 away from the front end of the slide rail 1, the other hanging members 4, and the hanging member 4 close to the front end of the slide rail 1 and the front end of the slide rail 1 are all connected by elastic members 5. When the gear belt 94 drives the slider 3 to slide along the slide rail 1, the slider 3 will drive the several hanging members 4 to slide and unfold synchronously through the elastic members 5. Since the several elastic members 5 are subjected to the same force, the stretching length is consistent, so that the slider 3 and the several hanging members 4 slide synchronously and equidistantly, thereby achieving uniform unfolding of the curtain at all locations. At the same time, as the spring stretches, the distance between the slider 3 and the hanging member 4 away from the front end of the slide rail 1 gradually increases, and the hanging member 4 will pull the active rod 6 to slide, and then drive the driven rod 7 to slide in the opposite direction through the transmission member 8, so that the distance between the first hanging part 71 and the slider 3, and the distance between the slider 3 and the hanging member 4 away from the front end of the slide rail 1 are synchronously increased, and the same is true for the second sliding assembly.
[0039] Specifically, the elastic member 5 is a spring.
[0040] Furthermore, a front end belt buckle 33 and a rear end belt buckle 34 are fixedly provided in sequence on one side wall of the slider 3 along the length direction of the slide rail 1. The front end belt buckle 33 is buckled on the front end of the gear belt 94, and the rear end belt buckle 34 is buckled on the rear end of the gear belt 94, so that the front end and the rear end of the gear belt 94 are fixed to the slider 3 through the belt buckles, thereby realizing the connection between the two ends of the gear belt 94, and at the same time facilitating the gear belt 94 to drive the slider 3 to slide.
[0041] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
