首先参照图1和图2，并结合窗帘轨道为U型轨道对本申请的窗帘开合装置的一般性实施方式进行介绍。
如图1至图2所示，为了解决现有窗帘开合装置存在的安装不便的问题，本申请的窗帘开合装置包括外壳1、驱动滚轮组件2、电源组件3、挂接机构5和开关部4。外壳1的顶部形成有通孔，驱动滚轮组件2包括驱动机构和驱动轮(二者图中未示出)，驱动机构用于驱动驱动轮转动，驱动轮安装于外壳1内，且部分通过通孔伸出。电源组件3设置于外壳1内，用于为驱动机构供电。
挂接机构5设置有两个，沿驱动轮的滚动方向(即U型轨道7的延伸方向)设置于驱动轮的两侧，每个挂接机构5包括第一支架52、第二支架53、第一从动轮54和第二从动轮55，第一从动轮54可转动地设置于第一支架52，第二从动轮55可转动地设置于第二支架53，第一支架52和第二支架53中至少一个被设置成能够沿驱动轮的轴向(即与U型轨道7的延伸方向相垂直的水平方向)往复移动，该移动使得挂接机构5能够在安装位置与使用位置之间切换。
开关部4设置于外壳1并与挂接机构传动连接，并且开关部4设置成能够在外力作用下由第一位置切换至第二位置，在外力撤除时由第二位置复位至第一位置。当开关部4由第一位置枢转至第二位置时，挂接机构5能够由使用位置切换至安装位置；当开关部4由第二位置复位至第一位置时，挂接机构5能够由安装位置切换回使用位置。
本申请的窗帘开合装置在静止状态下，开关部4位于第一位置，挂接机构5处于使用位置。在使用时，首先向开关部4施加外力，令开关部4由第一位置切换至第二位置，与此同时挂接机构5会从使用位置切换至安装位置。接下来将窗帘开合装置移动至待安装位置，并撤除对开关部4施加的外力，此时开关部4由第二位置复位至第一位置，此时挂接机构5由安装位置切换回使用位置，如此，装置便挂接在U型轨道7上。挂置好后，驱动滚轮组件2中的驱动轮与U型轨道7的下侧面抵压，在驱动机构的带动下，驱动轮转动，通过驱动轮与U型轨道7之间的摩擦力实现在U型轨道7上的行走。行走过程中，窗帘开合装置带动U型轨道7上的窗帘挂钩移动，从而实现窗帘的自动开启和闭合。
从上述描述可以看出，通过设置开关部4，使得本申请的窗帘开合装置具有安装方便的优点。具体地，通过在外力作用下使开关部4由第一位置切换至第二位置，使得挂接机构5能够由使用位置切换至安装位置，此时即可将窗帘开合装置方便地移动至窗帘轨道的待安装位置，然后在外力撤除时，开关部4由第二位置复位至第一位置，使得挂接机构5由安装位置切换至使用位置，即可将窗帘开合装置安装到窗帘轨道上。换句话说，通过简单的开关的动作，即可实现装置的安装，大大简化了窗帘开合装置的安装过程。
下面进一步参照图1至图6B，对本申请的窗帘开合装置的一种较为优选的实施方式进行描述。
首先参见图3，外壳1包括前壳11和后壳12，前壳11与后壳12通过卡接、螺接等方式安装到一起。前壳11与后壳12的顶部各形成有一个缺口(图中未示出)，在安装好后，外壳1内形成空腔，两个缺口围设形成通孔。驱动滚轮组件2包括驱动机构和驱动轮，驱动机构为电机，电机的输出轴与驱动轮传动连接，如与驱动轮直接连接或通过传动组件与驱动轮连接等。驱动滚轮组件2安装在外壳1的空腔中，安装好后，驱动轮部分通过通孔伸出并可相对于外壳1转动。需要说明的是，现有技术中驱动滚轮组件2的形式和原理已经较为普遍，本申请中对驱动滚轮组件2的具体形式不作限制，任何能够满足本申请安装条件的驱动滚轮组件2均可应用于本申请中。
继续参见图3，电源组件3包括电池31和电路板32，电池31可采用锂电池31，其与电路板32连接，电路板32与电机连接，电池31用于为电机供电，电路板32用于控制电机的启停，上述连接和控制方式在本领域较为常用，因此不再赘述。需要说明的是，本申请中，对于电机的启停指令的接收方式不作限制，其可以是用户使用遥控器、移动终端等与电路板32通信连接的设备发出，也可以是通过设置在外壳1的物理按钮发出，或者通过设置于室内任意位置、且与电路板32通信连接的按钮、开关发出。其中，与电路板32通信连接的方式可以是有线通信，也可以为无线通信，无线通信的方式可以但不限于蓝牙、红外、WiFi、ZigBee等方式。移动终端例如可以为手机、智能家居设备、可穿戴设备、智能移动设备、虚拟现实设备或其任意组合等。当然，在采用上述任一连接方式时，需要电路板32上搭载相应的模块，这些模块的设置和连接方式均为本领域的常规技术，因此不再赘述。
仍然参见图3，开关部4包括夹板，本申请中夹板设置有两个，分别为第一夹板41和第二夹板42，第一夹板41和第二夹板42分别通过一个转轴可枢转地设置于外壳1的相对设置的第一侧面和第二侧面。本申请中，第一夹板41通过第一转轴枢转连接于前壳11的前侧，第二夹板42通过第二转轴61枢转连接在后壳12的后侧。
具体地，以第一夹板41为例，其由第一本体411和第一盖体412两部分通过卡接、螺接等方式组合而成，第一盖体412的外侧面(即安装好后背离外壳1的侧面)下部开设有第一浅槽4121，第一浅槽4121成长条状且沿第一盖体412的宽度方向(即图3中左右方向)延伸。第一本体411的内侧面(即安装好后朝向外壳1的侧面)开设有第一容置槽4112，第一容置槽4112大致为矩形槽，第一容置槽4112的中部两端分别设置有一个第一轴座4111，每个第一轴座4111上开设有第一轴孔(未示出)。 前壳11的前侧面中部设置有第一通槽114，第一通槽114沿前壳11的宽度方向(图3中的左右方向)延伸，第一通槽114中设置有两个第二轴座113，每个第二轴座113上开设有第二轴孔。安装好后，第一转轴依次穿过第一轴孔、第二轴孔、第二轴孔和第一轴孔后将第一夹板41与前壳11可枢转地连接，两个第一轴座4111可枢转地位于第一通槽114中。
与此类似，第二夹板42由第二本体421和第二盖体422两部分通过卡接、螺接等方式组合而成，第二盖体422的外侧面(即安装好后背离外壳1的侧面)下部开设有第二浅槽(图中未示出)，第二浅槽成长条状且沿第二盖体422的宽度方向(即图3中左右方向)延伸。第二本体421的内侧面(即安装好后朝向外壳1的侧面)开设有第二容置槽4212，第二容置槽4212大致为矩形槽，第二容置槽4212的中部两端分别设置有一个第三轴座4211，每个第三轴座4211上开设有第三轴孔(未示出)。后壳12的后侧面中部设置有第二通槽124，第二通槽124沿后壳12的宽度方向(图3中的左右方向)延伸，第二通槽124中设置有两个第四轴座(图中未示出)，每个第四轴座上开设有第四轴孔。安装好后，第二转轴61依次穿过第三轴孔、第四轴孔、第四轴孔和第三轴孔后将第二夹板42与后壳12可枢转地连接，两个第三轴座4211可枢转地位于第二通槽124中。
前壳11的前侧面位于第二轴孔以下的部分、以及后壳12的后侧面位于第四轴孔以下的部分沿竖直方向(即图5中上下方向)由上至下逐渐收窄，并分别与底面圆弧过渡。
参见图1和图2，设置好后，从装置的侧面观察，在开关部4处于第一位置时，第一夹板41位于第一轴座4111以上的部分以及第二夹板42位于第三轴座4211以上的部分形成卡夹的“夹头”部分，第一夹板41位于第一轴座4111以下部分以及第二夹板42位于第三轴座4211以下的部分形成卡夹的“手柄”部分，当对该“手柄”施加外力时，第一夹板41和第二夹板42分别绕第一转轴和第二转轴61枢转至相对于外壳1张开的位置(即第二位置)，“夹头”部分相对于外壳1的顶部张开，此时前壳11的前侧面和后壳12的后侧面分别容纳于第一容置槽4112和第二容置槽4212内。当外力撤除时，第一夹板41和第二夹板42分别绕第一转轴和第二转轴61枢转至相对于外壳1闭合的位置(即第一位置)，此时“夹头”部分相对于外壳1的顶部闭合。
继续参照图3，窗帘开合装置还包括第二弹性件(未图示)和第三弹性件43。其中，第二弹性件被设置成第一夹板41在外力作用下由相对于外壳1闭合的位置枢转至相对于外壳1张开的位置时储存弹性势能，在外力撤除后释放弹性势能并因此使得第一夹板41由相对于外壳1张开的位置枢转至相对于外壳1闭合的位置。第三弹性件43被设置成第二夹板42在外力作用下由相对于外壳1闭合的位置枢转至相对于外壳1张开的位置时储存弹性势能，在外力撤除后释放弹性势能并因此使得第二夹板42由相对于外壳1张开的位置枢转至相对于外壳1闭合的位置。具体地，第二弹性件和第三弹性件43均为扭簧，以图3中示出的第三弹性件43为例，扭簧套接于第二转轴61上，且扭簧的两个伸出端分别抵接于第二容置槽4212和后壳12的后侧面上。
参见图3，对于每个挂接机构5，外壳1的顶面开设有伸出孔、第一侧面开设有第一滑孔112、第二侧面开设有第二滑孔122。具体地，前壳 11的顶面开设有两个第一豁口111，后壳12的顶面开设有两个第二豁口121，安装好后，两个第一豁口111与两个第二豁口121围设形成两个伸出孔。前壳11的前侧面上部开设有两个第一滑孔112，第一滑孔112为矩形长条孔，两个第一滑孔112沿前壳11的宽度方向并排设置。后壳12的后侧面上部开设有两个第二滑孔122，第二滑孔122也为矩形长条孔，两个第二滑孔122沿后壳12的宽度方向并排设置。
参见图4、图5A和图5B，挂接机构5包括罩壳51、第一支架52、第二支架53、第一从动轮54、第二从动轮55和第一弹性件56。
罩壳51通过卡接、螺接或抵接的方式设置于外壳1内，罩壳51的顶部设置有第一过孔5115和第二过孔5116，罩壳51内形成有第一滑槽和第二滑槽。具体地，参见图4，罩壳51包括彼此扣合连接的上壳体511和下壳体512，上壳体511和下壳体512分别一体成型。其中，上壳体511的内顶面中部设置有沿驱动轮的轴向延伸的上凸起结构5111，上凸起结构5111将上壳体511分隔为第一上半槽5112和第二上半槽5113，下壳体512的内底面中部设置有沿驱动轮的轴向延伸的下凸起结构5121，下凸起结构5121将下壳体512分隔为第一下半槽5122和第二下半槽5123，第一上半槽5112与第一下半槽5122围设形成第一滑槽，第二上半槽5113与第二下半槽5123围设形成第二滑槽。
上凸起结构5111与面下凸起结构5121之间形成有第一限位结构和第二限位结构。其中，上凸起结构5111沿其长度方向的两端分别设置第一上限位板5114和第二上限位板，下凸起结构5121沿其长度方向的两端分别设置第一下限位板5124和第二下限位板5125。安装好后，第一上限位板5114的自由端与第一下限位板5124的自由端抵接组成第一限位结构，第二上限位板的自由端与第二下限位板5125的自由端抵接形成第二限位结构。
参见图4和图5A，第一支架52包括第一滑块521和第一支杆522，第一支杆522的下端固定连接在第一滑块521上，第一支杆522的上端为自由端，第一从动轮54可转动地设置于第一支杆522的上端。安装好后，第一滑块521可滑动地设置于第一滑槽，第一支杆522的上端从第一过孔5115伸出。与此类似地，第二支架53包括第二滑块531和第二支杆532，第二支杆532的下端固定连接在第二滑块531上，第二支杆532的上端为自由端，第二从动轮55可转动地设置于第二支杆532的上端。安装好后，第二滑块531可滑动地设置于第二滑槽，第二支杆532的上端从第二过孔5116伸出。
参见图4、图5A至图6B，第一弹性件56分别与第一滑块521和第二滑块531连接，第一弹性件56被设置成在挂接机构5处于安装位置时储存弹性势能。具体地，第一滑块521在靠近第二滑块531的侧面设置有第一安装座5211，第二滑块531在靠近第一滑块521的侧面设置有第二安装座5311，第一安装座5211和第二安装座5311上都形成有柱体，第一弹性件56为压缩弹簧，压缩弹簧的两端分别套接在第一安装座5211的柱体和第二安装座5311的柱体。在安装好后，压缩弹簧、第一安装座5211和第二安装座5311位于第一限位结构与第二限位结构之间，第一滑块521与第二滑块531同时沿外壳1外部向外壳1内部的方向滑动时，压缩弹簧被压缩从而储存弹性势能，该弹性势能释放时可以使得第一滑块521和第二滑块531分别向外壳1外部滑动，并且在压缩弹簧释放弹 性势能时，第一安装座5211背离压缩弹簧的一侧抵接于第一限位结构，第二安装座5311背离压缩弹簧的一侧抵接于第二限位结构。
参见图3，两个挂接机构5相较于驱动轮的转轴对称地安装在外壳1内，安装好后，第一过孔5115与和第二过孔5116与伸出孔相对应，第一支杆522的上端从伸出孔中伸出，第二支杆532的上端从伸出孔中伸出，第一滑块521的前端与第一滑孔112对应设置并能够从第一滑孔112伸出或缩回，第二滑块531的后端与第二滑孔122对应设置并能够从第二滑孔122中伸出或缩回。
下面结合图1至图2、图5A至图6B，对本申请的窗帘开合装置的安装过程进行说明。
如图2、图6A和图6B所示，窗帘开合装置处于静止状态时，开关部4处于第一位置，此时第一夹板41和第二夹板42在扭簧的作用下分别紧贴在前壳11的前侧面和后壳12的后侧面，第一滑块521在第一夹板41的抵压下被位于第一滑孔112处，第二滑块531在第二夹板42的抵压下位于第二滑孔122处，此时压缩弹簧储存弹性势能，挂接机构5处于使用位置。
如图1、图5A和图5B所示，当需要将窗帘开合装置安装到U型轨道7上时，首先用户单手捏住两个夹板的浅槽部分，并同时对第一夹板41和第二夹板42施力，两个夹板在力的作用下沿各自转轴枢转至相对于外壳1张开的位置，两个扭簧分别储存弹性势能。与此同时，第一滑块521在压缩弹簧的弹性势能释放作用下沿第一滑槽向第一滑孔112外滑动并由第一滑孔112伸出，第二滑块531在压缩弹簧的弹性势能释放作用下向沿第二滑槽向第二滑孔122外滑动并由第二滑孔122伸出，第一从动轮54与第二从动轮55彼此靠近并沿U型轨道7的长度方向大致处于同一直线上，即挂接机构5由使用位置切换至安装位置。此时，用户可将窗帘开合装置举升至U型轨道7的待安装位置，使得第一从动轮54和第二从动轮55通过U型轨道7底面的缝隙进入至轨道内部。
接下来参照图2、图6A和图6B，在举升至待安装位置后，用户撤除对两个夹板施加的力，在扭簧的带动下，第一夹板41和第二夹板42沿各自转轴枢转枢转至相对于外壳1闭合的位置。与此同时，第一夹板41抵压第一滑块521使得第一滑块521沿第一滑槽向第一滑孔112内部滑动，第二夹板42抵压第二滑块531使得第二滑块531沿第二滑槽向第二滑孔122内部滑动，直至第一夹板41和第二夹板42分别紧贴于前壳11的前侧面和后壳12的后侧面上，第一从动轮54与第二从动轮55彼此远离并分别抵压在U型轨道7内部的一个导轨上，即挂接机构5由安装位置切换至使用位置，此时窗帘开合装置挂置在工字型轨道8上。另外，驱动轮此时抵压在U型轨道7的下侧面，安装完成。
本领域技术人员能够理解，虽然上述实施方式中并未对驱动滚轮组件2如何与U型轨道7下侧面抵压进行详细说明，但这并非代表本申请无法实施。相反地，现有技术中对于窗帘开合装置安装好后，驱动滚轮组件2、特别是驱动轮如何抵压至U型轨道7的下方有多种不同的方案，本领域技术人员可以基于实际产品进行灵活选择。例如，可以通过在驱动滚轮组件2下方设置弹簧/弹片来实现驱动轮抵压在U型轨道7上；再如也可以将挂接机构5与外壳1之间弹性连接等。
上述设置方式的优点在于：通过设置两个夹板，使得本申请的窗帘开合装置使用方便，用户只需像使用普通“夹子”一样操作，即可实现装置的安装和拆卸，大大简化窗帘开合装置的安装过程。并且，第一夹板41和第二夹板42对称设置于外壳1的两侧，还使得窗帘开合装置安装好后，具有受力均匀、运行平稳、夹设牢固等优点。
通过将第一支架52和第二支架53均设置为可滑动，使得第一从动轮54和第二从动轮55均可移动，减小用户施力，安装更加轻松。
通过使用上凸起结构5111和下凸起结构5121将罩壳51分为第一滑槽和第二滑槽，能够提高第一支架52和第二支架53的移动稳定性，保证装置装拆精度。
通过设置第一弹性件56，使得在开关部4枢转至第二位置时，挂接机构5能够自动切换至安装位置，并且还能对第一夹板41和第二夹板42进行一定程度的抵压，辅助开关部4的打开，节省用户施力。
通过在罩壳51内形成第一限位结构和第二限位结构，能够对第一支架52和第二支架53的移动进行限位，使得压缩弹簧储存一定弹性势能，防止压缩弹簧脱离安装座。
通过在第一夹板41和第二夹板42的内侧分别开设第一容置槽4112和第二容置槽4212，并将第一轴座4111设置在第一容置槽4112、第三轴座4211设置在第二容置槽4212，以及在外壳1的两侧分别设置第一通槽114和第二通槽124，将第二轴座113和第四轴座分别设置在第一通槽114和第二通槽124内，能够在减小装置的整体厚度，方便用户进行装拆操作。
通过将外壳1的第一侧面位于第二轴孔一下的部分、外壳1的第二侧面位于第四轴孔一下的部分沿竖直方向由上至下逐渐收窄，再配合容置槽的设置，能够为第一夹板41和第二夹板42的枢转预留更大的空间，从而使两夹板具有更大的张开角度，方便安装。
通过在第一夹板41和第二夹板42的外侧下部分别开设第一浅槽4121和第二浅槽，方便用户施力，降低操作难度。
通过设置第二弹性件和第三弹性件43，使得两个夹板可以自动回弹，降低安装难度；并且在安装好后，两个弹性件能够提高装置的稳定性，避免两个夹板松动。
需要说明的是，上述优选的实施方式仅仅用于阐述本申请的原理，并非旨在于限制本申请的保护范围。在不偏离本申请原理的前提下，本领域技术人员可以对上述设置方式进行调整，以便本申请能够适用于更加具体的应用场景。
例如，虽然上述实施方式中是结合开关部4设置两个夹板，挂接机构5中第一支架52和第二支架53均可移动进行介绍的，但是这仅仅是本申请的较为优选的实施方式，在不偏离本申请原理的前提下，本领域技术人员可以对上述实施方式进行调整，只要调整后的技术方案能够实现“开关部4由第一位置切换至第二位置时，挂接机构5能够由使用位置切换至安装位置；当开关部4由第二位置复位至第一位置时，挂接机构5能够由安装位置切换至使用位置”的动作方式即可。
举例而言，在一种实施方式中，在其他设置方式不变的前提下，开关部4可以只设置一个夹板，相应地，挂接机构5中第一支架52可沿驱动轮的轴向往复移动，第二支架53相对于外壳1固定设置，如与外壳1 一体成型、或卡置在外壳1内部等，第一弹性件56仍然可设置在两夹板之间，或者也可以设置在第一夹板41与壳体之间。此时，夹板枢转至相对于外壳1张开的位置时，第一滑块521在第一弹性件56的弹力下向第一滑孔112外部滑动，实现挂接机构5由使用位置向安装位置的切换，夹板枢转至相对于外壳1闭合的位置时，夹板内侧抵压第一滑块521使得第一滑块521沿第一滑槽向第一滑孔112内部滑动，实现挂接机构5由安装位置向使用位置的切换。当然，本替换实施方式中，在设置第一支架52可滑动的前提下，也可以同时设置两个夹板，只不过两个夹板中只有一个夹板与第一支架52配合使用。
另一种可替换的实施方式中，支架与夹板之间还可以通过传动件实现传动连接，从而使得夹板的枢转可以带动支架往复移动。以第一夹板41和第一支架52为例，第一夹板41上可以设置铰接孔，第一支架52上对应设置第二铰接孔，第一铰接孔与第二铰接孔之间通过传动杆连接，传动杆两端分别与第一铰接孔和第二铰接孔铰接。如此，在第一夹板41枢转过程中，可以通过传动杆带动第一滑块521往复滑动，实现挂接机构5在安装位置与使用位置之间的切换。
再如，在另一种可替换的实施方式中，挂接机构5除设置在外壳1内，还可以设置在外壳1的外部，如在外壳1顶部设置导轨，将第一支架52可滑动的设置在导轨上。
例如，在一种可能的实施方式中，虽然上述实施例中是以外壳1包括前壳11和后壳12进行阐述的，但这种结构形式并非唯一，本领域技术人员可以对外壳1的具体结构进行调整，以便调整后的技术方案适用于更加具体的应用场景。例如，外壳1还可以设置为一体式结构、上下分体结构等。
再如，在一种可替换的实施方式中，两个夹板的枢转设置方式并非唯一，在满足两夹板能分别相对于外壳1枢转的前提下，本领域技术人员可以对其具体设置形式进行调整。例如，两个夹板可以通过同一个转轴可枢转地设置于外壳1的相对设置的两侧。具体地，以图3所示方位为例，可以在外壳1的左右两侧面的上边缘中部各设置一个共用轴座，然后令两个夹板位于同一侧的轴座同时与共用轴座枢转连接。更具体地，位于图3左侧的第一轴座4111和第三轴座4211通过一根短轴与位于外壳1左侧面的上边缘中部设置的共用轴座枢转连接，位于图3右侧的第一轴座4111和第三轴座4211通过另一根短轴与位于外壳1右侧面的上边缘中部设置的共用轴座枢转连接。
再如，在另一种可替换的实施方式中，上述实施方式是结合外壳1内设置电源组件3进行介绍的，但这种实施方式并非限制性地，本领域技术人员可以对上述电源组件3是否设置进行选择，还可以对电源组件3的具体设置方式进行调整。例如，在部分应用场景中，窗帘开合装置可以不设置电源组件3，而是由外接电源为驱动机构供电，如采用充电宝、外接太阳能电池31板等，此时只需在外壳1上相应地设置接口即可。再如，在设置电源组件3的前提下，电源组件3可以包括电路板32和电池31仓，电池31仓用于置放干电池31。
再如，在另一种可替换的实施方式中，第一弹性件56除采用压缩弹簧外，也可以采用板簧或弹性胶块，这种对第一弹性件56具体形式的替换并未偏离本申请原理。
再如，在另一种可替换的实施方式中，第二弹性件和第三弹性件43除了采用扭簧外，还可以采用其他零件进行替代。一种可能的实施方式中，第二弹性件和第三弹性件43中的一个或全部可以为压缩弹簧，压缩弹簧的两端分别抵接于夹板与外壳1之间。
再如，在保证窗帘开合装置具有外壳1、驱动滚轮组件2和开关部4，挂接机构5具有第一支架52、第二支架53、第一从动轮54和第二从动轮55的基础上，上述实施方式中的其他部件或结构本领域技术人员可以选择性地进行修改或删减。例如，挂接机构5的罩壳51可以省略、第一弹性件56可以删减，第一容置槽4112、第二容置槽4212、第一浅槽4121、第二浅槽、外壳1侧面的收窄等结构可以修改或省略。
当然，上述可以替换的实施方式之间、以及可以替换的实施方式和优选的实施方式之间还可以交叉配合使用，从而组合出新的实施方式以适用于更加具体的应用场景。
下面参照图7A和图7B，对本申请的窗帘开合装置应用于工字型轨道8进行简要介绍。
如图7A和图7B所示，与上述优选实施方式不同的是，本实施方式中，对挂接机构5的具体设置方式进行了调整，使得窗帘开合装置可以应用于工字型轨道8。
具体地，如图7A和图7B所示，挂接机构5中，第一支架52和第二支架53仍然都可以沿驱动轮的轴向往复移动。不同的是，本实施方式中无论挂接机构5处于安装位置还是使用位置，第一从动轮54和第二从动轮55均处于相向设置的状态。而上一实施方式中，第一从动轮54与第二从动轮55始终处于相互背离的状态。实际制作过程中，只需调整第一支杆522和第二支杆532在第一滑块521和第二滑块531的位置，并相应地调整第一过孔5115、第二过孔5116和伸出孔的位置即可实现两个从动轮始终相向设置。
下面对本实施方式中的窗帘开合装置的安装过程进行简要说明。如图7A所示，当施加外力使得第一夹板41和第二夹板42相对于外壳1枢转张开的位置时，在第一弹性件56的弹力作用下第一滑块521和第二滑块531分别向第一滑孔112和第二滑孔122外滑动，第一从动轮54与第二从动轮55彼此远离，即挂接机构5由使用位置切换至安装位置。此时，用户可将窗帘开合装置举升至工字型轨道8的待安装位置，使得工字型轨道8的底面可以进入第一从动轮54与第二从动轮55之间的空间中。如图7B所示，当外力消除时，第一夹板41和第二夹板42相对于外壳1枢转至闭合的位置，第一夹板41抵压第一滑块521使得第一滑块521沿第一滑槽向第一滑孔112内部滑动，第二夹板42抵压第二滑块531使得第二滑块531沿第二滑槽向第二滑孔122内部滑动，第一从动轮54与第二从动轮55彼此靠近并分别抵压在工字型轨道8底部的一个导轨上，即挂接机构5由安装位置切换至使用位置，此时窗帘开合装置挂置在工字型轨道8上，安装完毕。
下面参照图8，对本申请的开关部的另外一种设置方式进行简单介绍。
如图8所示，与上述优选实施方式不同的是，开关部4的具体形式为按钮，本实施方式中按钮设置有两个，分别为第一按钮44和第二按钮(图中未示出)，第一按钮44通过第四弹性件设置嵌设在前壳11的前 侧面开设的第一嵌设孔115内，并且第一按钮44部分伸入到前壳11的内部。第二按钮通过第五弹性件嵌设在后壳12的后侧面设置的第二嵌设孔内，并且第二按钮部分伸入到后壳12的内部。其中，第四弹性件被设置成第一按钮44在外力作用下被按下时储存弹性势能，在外力撤除时，该弹性势能释放并带动第一按钮44复位至初始位置。与此类似地，第五弹性件被设置成第二按钮在外力作用下被按下时储存弹性势能，在外力撤除时，该弹性势能释放并带动第二按钮复位至初始位置。换句话说，两个按钮在无外力状态下的初始位置为开关部4的第一位置，两个按钮被按下的位置为开关部4的第二位置。
本实施方式中，第四弹性件和第五弹性件均可以为压缩弹簧或弹性胶块。
在上述设置方式下，挂接机构5的设置方式与上述优选实施方式也稍有不同。具体地，挂接机构5仍然与上述优选实施方式中采用相同的零部件，不同的是，在挂接机构5处于安装位置时，第一弹性件56被压缩储存弹性势能，此时两从动轮处于彼此靠近的状态。换句话说，在开关部4由第一位置移动至第二位置、也即两个按钮在外力作用下被按下时，两个按钮的内侧面分别推动两个滑块向滑槽内滑动，该滑动使得两从动轮彼此靠近，此时第一弹性件56被压缩而储存弹性势能，挂接机构5处于安装位置。在外力撤除开关部4由第二位置复位至第一位置、即外力撤除两个按钮分别在第四弹性件和第五弹性件的作用下被顶起时，两个滑块在第一弹性件56的弹性势能释放作用下各自向滑槽外滑动并分别与两个按钮相抵接，此时第一弹性件56可以储存微小的弹性势能以保持两个滑块之间的位置相对固定。当然两个滑块也可以不抵接在按钮内侧面上，此时第一天行健56处于无弹性势能状态。
在上述设置方式下，当施加外力使得第一按钮44和第二按钮被按下时，在第一按钮44和第二按钮的推动下第一滑块521和第二滑块531分别向第一滑槽和第二滑槽内滑动，第一从动轮54与第二从动轮55彼此靠近，即挂接机构5由使用位置切换至安装位置，此时第一弹性件56储存弹性势能。此时，用户可将窗帘开合装置举升至U型轨道的待安装位置，使得第一从动轮54和第二从动轮55进入U型轨道底部的缝隙中。当外力消除时，第一按钮44和第二按钮在压缩弹簧的弹力势能释放下向外壳1外弹起，第一滑块521在第一弹性件56的弹性势能释放下沿第一滑槽向外部滑动，第二滑块531在第一弹性件56的弹性势能释放下沿第二滑槽向外部滑动，第一从动轮54与第二从动轮55彼此远离并分别抵压在U型轨道内部的一个导轨上，即挂接机构5由安装位置切换至使用位置，此时窗帘开合装置挂置在U型轨道上，安装完毕。
一种可替换的实施方式中，还可以将第一按钮44和第二按钮的长度缩短，并在第一按钮44与第一滑块521之间设置传动板实现二者的传动连接，在第二按钮与第二滑块531之间设置传动板实现二者的传动连接。
一种可替换的实施方式中，还可以将第一按钮44和第二按钮整体设置在外壳1的外侧，并保留第一滑孔112和第二滑孔122，然后通过在第一按钮44和第二按钮上设置凸起结构，并将凸起结构由相应的滑孔伸入外壳1内与滑块相抵接，同样可以实现挂接机构5在使用位置与安装位置之间的切换。
另一种可替换的实施方式中，还可以在保留第一滑孔112和第二滑孔122的前提下，使第一滑块521和第二滑块531分别通过对应的滑孔伸出，然后将第一按钮44和第二按钮整体设置在外壳1的外侧，通过按钮按下过程中抵压伸出的滑块来实现两滑块滑动的目的，从而实现挂接机构5在使用位置与安装位置之间的切换。
当然，上述优选实施方式中的拓展技术方案，也适用于本实施方式，例如，在只有一个支架可往复移动时，按钮可以只设置一个。再如，滑块与按钮之间也可以选择通过铰接杆铰接来实现传动等。
需要说明的是，尽管这里针对开关部4仅提供了两种实施方式，但是，本领域技术人员应该理解的是，本申请对现有技术的贡献体现在通过开关部4的简单开关动作对挂接机构5的位置进行调整，进而实现装置的安装，其保护范围不应局限于上述两种开关部的设置形式，因此，本领域技术人员可以采用其他形式的开关部4来实现本申请的技术目的。例如，在可能的实施方式下，挂接机构5还可以通过拨杆、拨块等进行驱动。
本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本申请的范围之内并且形成不同的实施例。例如，在本申请的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
至此，已经结合附图所示的优选实施方式描述了本申请的技术方案，但是，本领域技术人员容易理解的是，本申请的保护范围显然不局限于这些具体实施方式。在不偏离本申请的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
