Description

Technical Field

[0001] The present application relates to the technical field of electric curtains, and in particular to a dual-drive curtain transmission mechanism. Background Art

[0002] When double-layer curtains realize the function of automatic closing and opening, they usually need to cooperate with corresponding transmission mechanisms to provide a power source for pulling the curtains.

[0003] In the related art, the transmission mechanism includes a transmission motor, a driving roller and a slide rail bracket. A double-layer slide rail is arranged on the slide rail bracket. The double-layer slide rail is extended in the horizontal direction and has a storage groove. The driving roller is rotatably connected in the storage groove so that the curtain can be rolled up on the outer wall of the driving roller. The transmission motor is fixedly connected to the end of the slide rail bracket to drive the transmission roller to rotate in different directions. When different motors rotate, the corresponding curtain can be rolled up or unfolded.

[0004] With respect to the above-mentioned related technologies, after the double-layer slide rails of the slide rail bracket are extended in the horizontal direction, the space occupied in the extended horizontal direction is relatively large. Therefore, when the transmission mechanism and the slide rail bracket are installed, the space occupied by the slide rail bracket in the extension direction of the double-layer slide rails is further increased. The installation of the transmission mechanism is prone to installation inconvenience due to the relatively small space in the horizontal direction of the slide rail bracket. Utility Model Content

[0037] The following will further elaborate on this application in conjunction with the attached Figures 1-5 drawings. In this embodiment, the direction indicated by the z-axis of the coordinate axis in the figure is defined as up, the direction opposite to the z-axis is down, the direction indicated by the y-axis is forward, the direction opposite to the y-axis is backward, the direction indicated by the x-axis is left, and the direction opposite to the x-axis is right.

[0038] Embodiment 1:

[0039] This embodiment of the present application discloses a dual-drive curtain transmission mechanism. Referring to Figure 1 , the dual-drive curtain transmission mechanism includes a slide rail bracket 1 and a transmission assembly 2. The slide rail bracket 1 includes a first slide rail 11 and a second slide rail 12. The first slide rail 11 is fixedly arranged on the upper surface of the second slide rail 12, and the first slide rail 11 and the second slide rail 12 are arranged obliquely in the vertical direction. There are two sets of transmission assemblies 2, and the two sets of transmission assemblies 2 are respectively connected to the first slide rail 11 and the second slide rail 12, and are used to drive the winding and unwinding of two different layers of curtains on the first slide rail 11 and the second slide rail 12, so as to reduce the space occupied by the first slide rail 11 and the second slide rail 12 in the front-rear horizontal direction, and facilitate the installation and adjustment of the transmission assembly 2 in a narrow installation space.

[0040] Referring to Figure 1 and Figure 2 , it should be further noted that the first slide rail 11 protrudes forward of the second slide rail 12 in the horizontal direction. The first slide rail 11 is provided with a first storage groove 111, and the notch of the first storage groove 111 is arranged to incline downward toward the front side. The front side wall of the second slide rail 12 is provided with a second storage groove 121, and the notch of the second storage groove 121 is arranged to face downward. Thus, when the curtain drops from the first storage groove 111, it is not easy to directly interfere with the notch of the first storage groove 111, and the two layers of curtains are arranged in parallel and spaced apart in the vertical direction.

[0041] Referring to Figure 3 , there are two sets of transmission assemblies 2. One set of transmission assembly 2 is respectively arranged at the left end of the first slide rail 11, and the other set of transmission assembly 2 is arranged at the right end of the first slide rail 11. The transmission assembly 2 at the left end is used to drive the winding and unwinding of the curtain in the first storage groove 111, and the transmission assembly 2 at the right end is used to drive the winding and unwinding of the curtain in the second storage groove 121, so that the installation of the two sets of transmission assemblies 2 is symmetrical and compact.

[0042] Among them, both groups of transmission components 2 include a tubular motor 21 and a transmission roller 22. The two ends of the first sliding rail and the second sliding rail are detachably connected with end protection covers 3. The surface of the end protection cover 3 facing the end of the first sliding rail 11 is provided with a clearance groove 31. The bottom of the clearance groove 31 begins to have rotation holes 311. The number of rotation holes 311 corresponds to the number of transmission rollers 22. The two ends of the transmission roller 22 are fixedly connected with a transmission rod 221. The transmission rod 221 and the transmission roller 22 are coaxially arranged. During installation, the adjacent ends of the transmission rod are inserted and rotatably connected to the corresponding rotation holes 311, so that the corresponding ends of the two transmission rollers 22 are limited and the two transmission rollers 22 are in a state of being parallel to each other. Before installing the transmission roller 22, the curtain and the transmission roller 22 are pre-wound.

[0043] In addition, refer to Figure 2 and Figure 3 It should be further explained that a mounting groove 13 is provided between the first slide rail 11 and the second slide rail 12, and the mounting groove 13 is for the tubular motor 21 to be embedded and fixed by screws, so that the output shaft of the tubular motor 21 protrudes from the adjacent side end surface of the first slide rail 11, and a driving gear 23 is fixedly provided on the output shaft of the tubular motor 21 in a concentric arrangement, and the driving gear 23 is fixedly connected to the output shaft, and a driven gear 24 is fixedly provided on the transmission rod 221 on the adjacent end of the transmission roller 22, and the driving gear 23 and the driven gear 24 are meshed and transmitted, so that when the output shaft of the tubular motor 21 rotates in different directions, it can drive the roller blind on the transmission roller 22 to be rolled up or unfolded.

[0044] In addition, refer to Figure 3 and Figure 4 , the facing side walls of the two end protection covers 3 are fixedly connected with plug-in blocks 32, and the edge side walls of the first slide rail 11 and the second slide rail 12 are provided with limiting slots 14, and the limiting slots 14 include a first limiting slot 141 and a second limiting slot 142. The number of the first limiting slot 141 and the second limiting slot 142 is set to two, and the two first limiting slots 141 are respectively provided at the front and rear edge side walls of the first slide rail 11 close to the upper side, and the two second limiting slots 142 are respectively provided at the front and rear edge side walls of the second slide rail 12 close to the lower side. The number of corresponding plug-in blocks 32 corresponds to the number of first limiting slots 141 and second limiting slots 142. When the plug-in blocks 32 are inserted into the corresponding first limiting slots 141 and second limiting slots 142, the end protection cover 3 limits the four diagonal edge side walls of the first slide rail 11 and the second slide rail 12, so that the connection firmness between the end protection cover 3 and the first slide rail 11 and the second slide rail 12 is increased.

[0045] Reference Figure 4In order to further increase the connection stability between the end protection cover 3 and the first slide rail 11 and the second slide rail 12, an embedding groove 112 begins to be provided on the rear side wall close to the upper side of the first slide rail 11, and an extension plate 33 is fixedly connected to the edge side wall of the end protection cover 3 facing the first slide rail 11. When the extension plate 33 is inserted into the embedding groove 112, it abuts against the front inner wall of the embedding groove 112. Furthermore, the extension plate 33 is connected and fixed to the first slide rail 11 by screws.

[0046] The implementation principle of a dual-drive curtain transmission mechanism in the embodiment of the present application is as follows: the first slide rail 11 and the second slide rail 12 are arranged tilted in the vertical direction, and two tubular motors 21 are respectively arranged in the give way groove 31, wherein one tubular motor 21 is transmission-connected to the transmission roller 22 in the first receiving groove 111, and the other tubular motor 21 is transmission-connected to the transmission roller 22 in the second receiving groove 121, so as to drive the two layers of curtains wound on the transmission roller 22 to be rolled up or unfolded. Compared with being arranged in the horizontal direction, the first slide rail 11 and the second slide rail 12 can reduce the space occupied in the horizontal direction, so that it is convenient to assemble and adjust when the installation space in the horizontal direction is small.

[0047] Embodiment 2:

[0048] Reference Figure 3 and Figure 5 Compared with the first embodiment, the second embodiment is different in that the driving gear 23 and the driven gear 24 are embedded in and rotatably connected to the bottom of the clearance groove 31, and a meshing transmission is formed between the driving gear 23 and the driven gear 24.

[0049] Specifically, a sleeve shaft 312 is fixedly provided at the bottom of the give way groove 31, and the number of the sleeve shafts 312 is set to two. The two sleeve shafts 312 are respectively sleeved and rotatably connected to the corresponding driving gear 23 or the driven gear 24, and when the driving gear 23 and the driven gear 24 are sleeved on the circumferential side wall of the sleeve shaft 312, the sleeve shaft 312 is partially inserted into the sleeve hole 25 of the driving gear 23 or the driven gear 24, so that during subsequent further installation, the output shaft of the driven roller and the tubular motor 21 is inserted into the corresponding sleeve hole 25, and is bonded and fixed to the driven gear 24 or the driving gear 23, so that the driven gear 24 can rotate with the transmission roller 22, the driving gear 23 can rotate with the output shaft of the tubular motor 21, and the driving gear 23 and the driven gear 24 are not limited.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
