进一步地，螺母组件还包括连接在边框开口处的连接板，连接板上设置有避让安装板的避让孔，避让孔与安装板导向配合；安装板包括板本体及设置于板本体侧壁上的导向凸筋，避让孔的孔壁上设置有与导向凸筋导向配合的导向槽。
进一步地，安装板包括板本体及设置于板本体的顶端的第一连接片，第一连接片与板本体成角度设置，第一连接片通过定位结构与电机组件的顶部连接。
进一步地，安装板还包括设置于板本体的底端的第二连接片，第二连接片与板本体成角度设置，丝杠的底部具有连接柱及与连接柱连接的止挡部，连接柱的直径小于丝杠的直径，止挡部凸出于连接柱的侧壁，第二连接片套设于连接柱外并与止挡部止挡配合。
进一步地，第二连接片包括与板本体的底端连接的第一片体及与第一片体叠置设置并卡接连接的第二片体，第一片体套设在连接柱的外侧并具有供连接柱通过的第一缺口，第二片体套设在连接柱的外侧并具有供连接柱通过的第二缺口。
进一步地，第一缺口包括与连接柱配合的第一圆孔段及使第一圆孔段与第一片体的外部连通的第一贯通段，第一贯通段的宽度小于第一圆孔段的直径，第二缺口包括与连接柱配合的第二圆孔段及使第二圆孔段与第二片体的外部连通的第二贯通段，第二贯通段的宽度小于第二圆孔段的直径，第一片体上设置有卡入第二贯通段内的第一卡台，第二片体上设置有卡入第一贯通段内的第二卡台。
进一步地，第一卡台的侧壁面和第一贯通段的侧壁面均由第一片体内部至第一片体外部方向逐渐扩张，第二卡台的侧壁面和第二贯通段的侧壁面均由第二片体内部至第二片体外部方向逐渐扩张。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
如图1至图8所示，本实施例的升降装置包括：升降架10、第一支撑件20、第二支撑件30、驱动机构40和行程组件60。第一支撑件20和第二支撑件30间隔地设置于升降架10的底面或者内侧。第一支撑件20包括第一支腿和位置可调节地与第一支腿配合的第二支腿。第二支腿与升降架10连接，第二支撑件30包括第三支腿和位置可调节与第三支腿配合的第四支腿，第四支腿与升降架10连接。驱动机构40包括连接于第二支腿的电机组件41及与电机组件41驱动配合的丝杠42。第一支腿上固定有与丝杠42传动配合的螺母组件50。行程组件60包括安装板61及间隔地设置于安装板61的上位置开关62和下位置开关63。安装板61的顶端与电机组件41连接，螺母组件50位于上位置开关62和下位置开关63之间。其中，丝 杠42相对于螺母组件50转动以带动第二支腿和第四支腿进行升降，并使螺母组件50具有与上位置开关62触发配合的上极限位置以及与下位置开关63触发配合的下极限位置。这样，第二支腿不会超出限制区间，避免破坏支腿的内部结构。
应用本实施例的技术方案，行程组件60包括安装板61及间隔地设置于安装板61的上位置开关62和下位置开关63。安装板61的顶端与电机组件41连接，螺母组件50位于上位置开关62和下位置开关63之间。其中，电机组件41驱动丝杠42转动，丝杠42能够相对于螺母组件50转动以带动第二支腿和第四支腿进行升降。第二支腿升降能够带动升降架10进行升降运动，并使螺母组件50具有与上位置开关62触发配合的上极限位置以及与下位置开关63触发配合的下极限位置。这样，由于上位置开关62和下位置开关63能够预先安装在安装板61上组成一套行程组件60，这样可将行程组件60直接装配至电机组件41上，无需再分别将上位置开关62和下位置开关63安装第一支腿上，使得行程组件60安装方便，能够提高升降装置组装效率。因此，本实施例的技术方案能够解决相关技术中的电动升降桌的组装效率较低的问题。上述的升降装置优选为升降桌。
需要说明的是，螺母组件50位于上位置开关62和下位置开关63之间是指：螺母组件50不仅能够在上位置开关62和下位置开关63所形成的区域内移动，并且当螺母组件50处于上位置开关62时，螺母组件50的中心与上位置开关62的中心可以位于同一条水平线上。当螺母组件50处于下极限位置时，螺母组件50的中心与下位置开关63的中心可以位于同一条水平线上。
另外需要注意的是，螺母组件50处于下极限位置时升降桌处于最高状态，螺母组件50处于上极限位置时升降桌处于最低状态。即处于最高状态时的升降桌的升降架的顶面至地面之间的距离大于处于最低状态时的升降桌的升降架的顶面至地面之间的距离。
本实施例中的升降架10可以仅包括横梁，第二支腿与横梁的内侧连接，第四支腿与横梁的内侧连接。当然，在其他实施方式中，升降架可以仅包括桌板，第二支腿与桌板的底面连接，第四支腿与桌板的底面连接。升降架还可以包括桌板和横梁，横梁设置于桌板底部，第二支腿与横梁连接，第四支腿与横梁连接。
如图1至图5所示，第一支腿为第一内管21，第二支腿为位置可调节地套设在第一内管21外的第一外管22，第三支腿为第二内管31，第四支腿为位置可调节地套设在第二内管31外的第二外管32。这样，第一内管21和第一外管22嵌套配合防止第一外管22在升降过程中发生偏斜。同时，第二内管31与第二外管32嵌套配合防止第二外管32在升降过程中发生偏斜。为了使升降装置的结构紧凑，安装板61穿设于螺母组件50和第一内管21内。并且，第一内管21能够防护安装板61，防止安装板61上的上位置开关62和下位置开关63暴露在降装置的外部而发生干涉的问题。
当然，在图中示出的实施例中，第一支腿可以为第一支杆，第二支腿可以为第二支杆，第三支腿可以为第三支杆，第四支腿可以为第四支杆。第一支杆和第二支杆之间设置有第一 滑槽和第一滑块的导向配合的第一导向结构，第三支杆和第四支杆之间设置有第二滑槽和第二滑块的导向配合的第二导向结构。
如图1至图8所示，螺母组件50包括螺母51及围设在螺母51外的边框52。边框52固定于第一内管21内，安装板61位于边框52的内侧和螺母51的外侧之间，螺母51上设置有触发件53。为了使螺母组件50具有与上位置开关62触发配合的上极限位置以及与下位置开关63触发配合的下极限位置，触发件53能够与上位置开关62和下位置开关63触发配合。
具体地，边框52包括围设在螺母51外的围板及设置在螺母51的外侧壁和围板的内侧壁之间的连接筋，这样，螺母51能够稳定地位于边框52内。
如图9和图10所示，触发件53包括与螺母51的外壁面连接的第一斜面部531和第二斜面部532。第一斜面部531的底部凸出于第一斜面部531的顶部且与上位置开关62触发配合。这样，安装板61上的上位置开关62随第一外管22上升的过程中，上位置开关62的触点与第一斜面部531的顶部至底部逐渐接触，以使第一斜面部531完全压在上位置开关62的触点上，以有效地触发上位置开关62，以使螺母组件50停在上极限位置。第二斜面部532的顶部凸出于第二斜面部532的底部且与下位置开关63触发配合。安装板61上的下位置开关63随第一外管22下降的过程中，下位置开关63的触点由第二斜面部532的底部至顶部逐渐接触，以使第二斜面部532完全压在下位置开关63的触点上，以有效地触发下位置开关63，以使螺母组件50停在下极限位置。
如图6和图11所示，螺母组件50还包括连接在边框52开口处的连接板54。安装板61穿设于螺母组件50和第一内管21内，为了使螺母组件50避让安装板61，连接板54上设置有避让安装板61的避让孔55。同时为了使安装板61随第一外管22升降的过程中能够沿预定的轨道移动，避让孔55与安装板61导向配合。安装板61包括板本体611及设置于板本体611侧壁上的导向凸筋612，避让孔55的孔壁上设置有与导向凸筋612导向配合的导向槽551。这样，导向凸筋612与导向槽551导向配合能够形成预定的轨道，防止发生偏转，以使安装板61升降更加的平稳，进而使得升降装置的稳定性较高。
如图7和图11所示，安装板61包括板本体611及设置于板本体611的顶端的第一连接片613。为了便于第一连接片613与电机组件41的顶部连接，第一连接片613与板本体611成角度设置，第一连接片613通过定位结构70与电机组件41的顶部连接。这样，第一连接片613通过定位结构70能够正确地安装在电机组件41的顶部，提供了安装效率。
在本实施例中，具体地，定位结构70包括设置在电机组件41的顶部的凸台及设置于第一连接片613的定位孔，凸台对准在定位孔内。这样第一连接片613与电机组件41的顶部无需使用螺钉连接，便能够安放到位，有效地提高了电机组件41和安装板61之间的安装效率。
如图8、图9和图11所示，安装板61还包括设置于板本体611的底端的第二连接片614，为了便于第二连接片614与丝杠42的底部连接，第二连接片614与板本体611成角度设置。丝杠42的底部具有连接柱421及与连接柱421连接的止挡部422，连接柱421的直径小于丝杠42的直径，止挡部422凸出于连接柱421的侧壁。第二连接片614套设于连接柱421外并 与止挡部422止挡配合，这样，止挡部422止挡第二连接片614，防止第二连接片614向下移动而脱离丝杠42的底部。
如图8、图9、图11以及图12所示，第二连接片614包括与板本体611的底端连接的第一片体6141及与第一片体6141叠置设置并卡接连接的第二片体6142。这样，第一片体6141和第二片体6142结构简单，组装更方便。第一片体6141套设在连接柱421的外侧并具有供连接柱421通过的第一缺口，第二片体6142套设在连接柱421的外侧并具有供连接柱421通过的第二缺口。这样，连接柱421能够通过第一片体6141和第二片体6142，便于限制第二连接片614沿连接柱421的径向移动。同时止挡部422止挡第二片体6142，防止第二连接片614沿连接柱421的轴向向下移动。
如图8、图9、图11以及图12所示，第一缺口包括与连接柱421配合的第一圆孔段61411及使第一圆孔段61411与第一片体6141的外部连通的第一贯通段61412，第一贯通段61412的宽度小于第一圆孔段61411的直径。这样，第一片体6141能够直接从连接柱421的外侧经过第一贯通段61412和第一圆孔段61411后，使第一片体6141套在连接柱421外，便于组装，无需将第一片体6141由下至上的方式套设在连接柱421的外部。第二缺口包括与连接柱421配合的第二圆孔段61421及使第二圆孔段61421与第二片体6142的外部连通的第二贯通段61422。第二贯通段61422的宽度小于第二圆孔段61421的直径。这样，第二片体6142能够直接从连接柱421的外侧经过第二贯通段61422和第二圆孔段61421后，使第二片体6142套在连接柱421外，便于组装，无需将第二片体6142由下至上的方式套设在连接柱421的外部。并且，由于第一片体6141上设置有卡入第二贯通段61422内的第一卡台61413，第二片体6142上设置有卡入第一贯通段61412内的第二卡台61423，便于将第一片体6141与第二片体6142叠置后并卡接连接在一起，使得结构更加的紧凑。此时第二连接片614与丝杠42的底部连接不使用螺钉，并且第一连接片613与电机组件41的顶部连接也不使用螺钉，进而安装板61与电机组件41和丝杠42的连接均不使用螺钉。上述安装方式操作简单，使得升降装置拆装十分方便，成本也较低。
如图8和图12所示，为了保证第二贯通段61422与第一卡台61413的卡接更加的牢固，第一贯通段61412与第二卡台61423的卡接更加的牢固，第一卡台61413的侧壁面和第一贯通段61412的侧壁面均由第一片体6141内部至第一片体6141外部方向逐渐扩张。第二卡台61423的侧壁面和第二贯通段61422的侧壁面均由第二片体6142内部至第二片体6142外部方向逐渐扩张。这样，第一卡台61413由第一片体6141外部至第一片体6141内部方向卡入至第二贯通段61422内的过程中，第一卡台61413的侧壁面与第二贯通段61422的侧壁面相互挤压的越来越紧，保证了第一卡台61413卡入至第二贯通段61422内的卡接效果。同理也保证了第二卡台61423卡入至第一贯通段61412内的卡接效果。
如图3至图11所示，为了便于上位置开关62和下位置开关63均容易通电，行程组件60还包括连接于安装板61的电路板64。上位置开关62和下位置开关63均连接于电路板64。
如图9至图12所示，为了便于拿取第二连接片614，第二连接片614的外壁面设置有凸耳结构6143。具体地，凸耳结构6143为多个，多个凸耳结构6143中的一部分设置于第一片体6141，多个凸耳结构6143中的另一部分设置于第二片体6142。
如图1至图5、图9至图11所示，电机组件41包括固定架411、电机412及齿轮传动结构413。固定架411与第一外管22连接，电机412和齿轮传动结构413均安装于固定架411，电机412通过齿轮传动结构413驱动丝杠42转动，第一连接片613通过定位结构70与固定架411的顶部连接。具体地，升降架10可以仅包括横梁，第二支腿与横梁连接，第四支腿与横梁连接，固定架411包括间隔连接在横梁上的折板及箱体，第一连接片613通过定位结构70与箱体的顶部连接。电机412连接在折板上，齿轮传动结构413的齿轮组件位于箱体内，齿轮传动结构413的传动杆用于将电机412的转动传递给齿轮组件，齿轮组件驱动丝杠42转动。为了便于分别支撑第一内管21和第二内管31，升降装置还包括连接于第一内管21底部的第一底座81及连接于第二内管31底部的第二底座82。
本实施例的升降装置的一套行程组件及其安装方式，可以适配不同的升降桌，并且安装该套行程组件的升降桌可以省去手控开关及带软件的控制盒，成本较低。并且在使用中即使发生老化或损坏，更换和维修简单快捷。
