下面参考附图和可选的实施例对本申请作详细说明。
如图1所示,本申请公开了一种电动窗帘,包括电机11和可伸缩电动窗帘轨道10,所述电机设置在所述电机接口110处驱动所述连接部的第一驱动部120转动以带动第一轨道部100或第二轨道部200的在连接部300的连接作用下完成伸缩。
如图2和图3所示,本申请还公开了一种可伸缩电动窗帘轨道,包括设置有第一环形传送带140的第一轨道部100、与所述第一轨道部100平行设置,设置有第二环形传送带230的第二轨道部200以及设置在所述第一轨道部的端部的连接部300,所述第一所述轨道部100和第二轨道部200通过所述连接部可进行相互平行伸缩移动,连接所述第一轨道部100和第二轨道部200,所述连接部300包括第一从动轮130,所述第一从动轮130可传动连接所述第一环形传送带140和所述第二环形传送带230;所述可伸缩电动窗帘轨道还包括:至少一个电机接口110,设置在所述第一轨道部或第二轨道部远离所述驱动连接部的一端;以及第一驱动部120,连接所述电机接口110,驱动所述第一轨道部上的第一环形传送带进行传动,并通过所述第一从动轮带动所述第二环形传送带传动;或驱动所述第二轨道部上的第二环形传送带进行传动,并通过所述第一从动轮带动所述第一环形传送带传动;其中,第一环形传送带与所述第二环形传送带的水平高度不同。
本申请中窗帘的伸缩轨道的总长度可调节,可以实现不同尺寸的窗户皆可适配,其第一轨道部100的第一环形传送带140和第二轨道部200中的第二环形传送带230的独立式设计,通过一个驱动部120,利用连接部300的从动轮,实现两个独立的环形传送带转动,从而带动窗帘开合,结构简单稳定可靠,不容易坏,减少了返修率;利用连接部,实现两个独立的环形传送带转动,从而带动窗帘开合,结构简单稳定可靠,不容易坏,减少了返修率,工厂按照一定的长度范围大批量生产,品质稳定,生产效率高,可进行伸缩调节,运输体积小,安装员到家安装,可根据实际的窗帘长度进行调整,适用范围广,与定制一样,更重要的在于在适配不同尺寸的窗户时,调节第一轨道部100和第二轨道部200的位置不会影响两个独立的环形传送带的安装,安装更便捷。
进一步的,所述第一轨道部100包括第一轮310,所述第一轮310和所述第一从动轮130分别设置在所述第一环形传送带140的两端的内侧,传动所述第一环形传送带转动;所述第二轨道部200包括第二轮320和第三轮330,分别设置在所述第二环形传送带230的两端的内侧,传动所述第二环形传送带转动;所述第三轮330远离所述第一轮310;所述第二轮靠近所述第一轮;其中,所述电机接口设置有两个,分别与所述第一轮和所述第三轮驱动连接,分别与所述第一轮和所述第三轮驱动连接;若第一驱动轮为第一轮,则电机11可以通过电机接口110连接第一轮310;也可以通过电机接口连接第三轮,此时第一驱动轮即为第三轮,如此在实际的安装过程中可以更加方便,可以使用不同的空间位置;例如,当安装时,左边 的空间有限不适宜安装电机,那么电机可以安装在右边,第三轮则作为第一驱动轮。
当然,所述电机接口仅设置有一个,所述电机接口与所述第一轮驱动连接,则所述第一驱动部即为所述的第一轮;或,所述电机接口与所述第三轮驱动连接,所述第一驱动部即为所述的第三轮,电机可以通过电机接口与驱动第一轮,或者通过电机接口驱动第三轮的。
进一步的,图4所示,所述第一从动轮包括离合轴芯131,所述离合轴芯131包括同轴心的第一轴132和第二轴133;所述第一环形传送带的一端绕所述离合轴芯的第一轴转动;所述第二环形传送带从所述第二轨道部绕出并套设至所述离合轴芯的第二轴上转动;所述第一环形传送带和所述第二环形传送带通过所述离合轴心相互传动连接,其中,所述第一轴和第二轴的直径相同,如此使第一环形传送带和第二环形传送带的转动速度相同,使得电机的寿命更长。
需要说明的是,所述离合轴芯让两组同步带形成整体联动,在实际使用时,两组同步带需先断开,轨道拉伸好长度以后,然后再插入离合轴芯,使两组皮带实现联动。
如图5和图7所示,所述第一环形传送带的水平高度低于所述第二环形传送带的水平高度,所述第一驱动部设置在所述第一轨道部远离所述连接部的一端,所述第一驱动部驱动所述第一轨道部上的第一环形传送带进行传动,并通过所述第一从动轮带动所述第二环形传送带传动;本方案中,电机连接第一驱动部,第一驱动部驱动上下两层皮带中的下层皮带,由下层皮转动通过离合轴芯带动上层皮带进行传动,如此更稳固,上层皮带不容易滑出。
当然,所述第一环形传送带与所述第二所述第一环形传送带平行设置的同时,第一环形传送带的水平高度低于所述第二环形传送带的水平高度,所述第一驱动部设置在所述第二轨道部远离所述连接部的一端,驱动所述第二轨道部上的第二环形传送带进行传动并通过所述第一从动轮带动所述第一环形传送带传动,可根据实际环境选择电机接口从而选定本方案。
为了使得第二环形传送带230可以更稳定的进行传送,如图7所示,所述连接部还包括第二从动轮210和第三从动轮220,所述第一从动轮130、第二从动轮210和第三从动轮220呈三角形分布,所述第二环形传送带230分别传动经过所述第二从动轮210、第一从动轮130以及第三从动轮220,所述第一从动轮130设置在所述第二环形传送带230内侧;所述第二从动轮210和第三从动轮220分别设置在所述第二环形传送带230外侧;所述第二从动轮和第三从动轮呈一排,设置在所述第一从动轮和第二轨道部之间,三个从动轮,呈三角形排布更具有稳定性,第二从动部与第三从动部对皮带进行限位,则第二环形传送带不易滑出,所述第二从动轮和第三从动轮的连线与所述第一环形带平行,使得第二环形传送带更加平缓传送转动。
进一步的考虑到第二环形传送带传送时的稳定性,所述第二从动轮和第三从动轮之间的距离d不大于所述第一从动轮轮轴直径的三倍,本方案中,控制第二从动轮和第三从动轮的 间距不大于所述第一从动轮轮轴直径的三倍,如此第二从动轮和第三从动轮的限位效果更好,防止间距过大而失去限位效果,导致第二环形传送带从轨道中滑出。
当然,所述第二从动轮和第三从动轮之间的距离在所述第一从动轮轮轴直径的0.3倍至所述第一从动轮轮轴直径之间,间距不易过小,否则皮带无法绕过。
如图8所示,所述第一轨道部100包括:第一侧板101、第二侧板102以及连接第一侧板101和第二侧板102的底板103;第二轨道部200包括:第一侧板201、第二侧板202以及连接第一侧板201和第二侧板202的底板203;其中所述第一轨道部100的第一侧板101与第二轨道部200的第一侧板201相邻,所述第一轨道部100的第二侧板102与第二轨道部200的第二侧板202相背;所述第一环形传送带140设置在第一轨道部100的底板上,所述第二环形传送带230设置在第二轨道部200的底板上;所述第一侧板101低于第二侧板102,所述第一轨道部的底板低于所述第二轨道部的底板;所述两个传动小车400分别设置在两个第二侧板上,所述第一轨道部100还包括第一固定结构150,所述第一固定结构150将传动小车400固定在所述第一环形传送带140上;所述第一轨道部100的传动小车400可在第一轨道部100的第二侧板102上滑动;所述第二轨道部200还包括第二固定结构240,所述第二固定结构240将传动小车400固定在所述第二环形传送带230上;所述第二轨道部200的传动小车400可在第二轨道部200的第二侧板上滑动。第二从动轮210和第一连接轴310皆只与环形传送带的一边接触,而环形传送带的另一边用于固定传动小车400,避免传动小车400的移动受阻,其中第二固定结构与第一固定结构相同,所述第一从动轮包括离合轴芯,所述离合轴芯包括同轴心的第一轴和第二轴,所述第一轴的外围设置有卡齿与所述第一环形传送带的卡齿相互啮合;所述第二轴的外围设置有卡齿与所述第二环形传送带的卡齿相互啮合,通过卡齿啮合,可以防止皮带打滑。
如图9所示,本申请所述第一轨道部100和第二轨道部200之间设置滑槽500,所述滑槽500包括凹钩和凸钩520所述第一轨道部100靠近所述第二轨道部200的一侧设置有凹钩510;所述第二轨道部200靠近所述第一轨道部100的一侧设置有凸钩520,所述凹钩510包括与所述第一轨道部100的侧板垂直的第一凸起511、与第一凸起511垂直的第二凸起512,所述凸钩520包括与所述第二轨道部200的侧板垂直的第三凸起521、与第三凸起521垂直的第四凸起522,所述第二凸起512卡接到第三凸起521与第四凸起522形成的凹槽内,所述第四凸起522卡接到第一凸起511和第二凸起512形成的凹槽内,所述第二凸起512的宽度从上到下依次增大,所述第四凸起522的宽度从上到下依次减小,这样的设计不仅使得本申请的第一轨道部100和第二轨道部200之间可以滑动,而且所述第二凸起512的宽度从上到下依次增大,所述第四凸起522的宽度从上到下依次减小,第二凸起512和第四凸起522相互挤压,使得第一轨道部100和第二轨道部200之间贴合更紧密。
本方案中,直接设置小车环抱第二侧板的结构,使得传动小车400在第二侧板上更稳定的移动,不会发生晃动,更进一步的,还可以在传动小车400与第二侧板之间设置滑动结构,例如滑轮等结构,以便减少摩擦阻力,同步带可以通过皮带扣驱动小车做左右移动,如此在窗帘开启或收缩的时候十分方便,另外皮带和轴之间以及轮之间互相啮合,在传动的过程中更加稳定,不会出现滑脱的现象,避免皮带打滑后滑出损坏皮带造成整个伸缩轨道的破坏,两组同步带属于单独动力封闭状态,离合轴芯让两组同步带形成整体联动,轨道在伸缩时会造成小车跑位,所以实际应用中,两组皮带先断开,轨道拉伸好长度以后,将小车单独拖到轨道的两端,然后再插入离合轴芯,是两组皮带联动,这样才能使小车的活动范围与实际长度对应。
如图10所示,公开了一种可以用于上述任一实施例中的可伸缩电动窗帘轨道的驱动方法,包括步骤:
S1:电机启动,朝第一方向转动,所述第一驱动部带动所述第一环形传送带进行传动,所述第一传送带通过所述连接部的第一从动轮带动所述第二传送带进行传动,以带动第一轨道上对应的窗帘和第二轨道上对应的窗帘对开运动;
S2:电机启动,朝第二方向转动,所述第一驱动部带动所述第一环形传送带进行传动,所述第一传送带通过所述连接部的第一从动轮带动所述第二传送带进行传动,以带动第一轨道上对应的窗帘和第二轨道上对应的窗帘对合运动;
其中,所述第一方向和所述第二方向相反。
在电机启动时,可以选择正转和反转,即向相反的方向进行转动,当电机朝第一方向转动时为正转,所述第一驱动部带动所述第一环形传送带进行传动,所述第一传送带通过所述连接部的第一从动轮带动所述第二传送带进行传动,那么第一轨道上和第二轨道上的传动小车往相反的方向进行移动,那么第一轨道上对应的窗帘和第二轨道上对应的窗帘朝两边收缩,从而打开窗帘,其中第一方向可以是顺时针方向。
若需要关闭窗帘,则电机选择反转,即朝第二方向转动,电机里面的结构逆时针进行转动,所述第一驱动部带动所述第一环形传送带进行传动,所述第一传送带通过所述连接部的第一从动轮带动所述第二传送带进行传动,那么第一轨道上和第二轨道上的传动小车相互靠近移动,那么第一轨道上对应的窗帘和第二轨道上对应的窗帘朝中间打开,从而合闭窗帘。
当然,也不一定是电机正转而最终使得窗帘向两边收缩打开,也可以是在电机正转时最终使得窗帘向中间打开,从而合并;需要说明的是,本方案中涉及到的各步骤的限定,在不影响具体方案实施的前提下,并不认定为对步骤先后顺序做出限定,写在前面的步骤可以是在先执行的,也可以是在后执行的,甚至也可以是同时执行的,只要能实施本方案,都应当视为属于本发明的保护范围。
以上内容是结合具体的可选实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本申请的保护范围。
