基于上述实施例，第一伸缩杆以及第二伸缩杆相互滑动套接形成一个伸缩杆结构，通过改变第一伸缩杆与第二伸缩杆之间的相对位置来调节伸缩结构对待升降部件的支撑长度，并通过锁紧件对调整后的第一伸缩杆以及第二伸缩杆之间的相对位置进行锁紧固定，降低了伸缩结构的调节难度。
在其中一些实施例中，第二伸缩杆具有沿其长度方向设置的调节槽，锁紧件依次穿设调节槽以及第一伸缩杆的活动端，其中，活动端为第一伸缩杆靠近第二伸缩杆的一端。

在其中一些实施例中，支撑机构还包括第一连接座以及第二连接座，第一连接座与第一伸缩杆远离第二伸缩杆的一端铰接，且与升降机构固定连接，第二连接座与第二伸缩杆远离第一伸缩杆的一端铰接，且与待升降部件固定连接。
基于上述实施例，第一连接座相当于第一伸缩杆与升降机构之间的中间连接结构件，第二连接座相当于第二伸缩杆与待升降部件之间的中间连接结构件，通过第一连接座以及第二连接座的设置，降低了支撑机构与待升降部件以及升降机构之间的安装难度；且第一连接座与第一伸缩杆铰接并与升降机构固定连接，第二连接座与第二伸缩杆铰接并与待升降部件固定连接，使得待升降部件、升降机构以及支撑机构之间形成一个三角形结构，进一步加强了该升降装置对待升降部件的支撑稳定性。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行详细说明。应当理解，此处所描述的实施例用以解释本申请，并不用于限定本申请。
相关技术中，对于垂直放置在地面上的显示屏，如运动场上的围栏显示屏，由于受到显示屏自身体积的影响，如显示屏的体积较大，其表现可以为显示屏的屏幅尺寸，在安装显示屏的过程中，由于无法调节显示屏的高度，从而无法保证显示屏的水平安装，也即显示屏安装后无法保证显示屏的背离地面的表面与水平面平行，故大幅度提高了显示屏的安装难度，例如当地面不平整时，普通的显示屏很难水平的安装在地面上以使显示屏的背离地面的表面与水平面平行，安装人员可能会借助其他垫件(如石块)来垫高显示屏，以使显示屏的背离地面的表面尽可能的与水平面平行，从而大幅度增加了显示屏的安装时间与安装难度。
且显示屏的安装高度过高会导致显示屏整体的重心偏高，从而使得显示屏在某些外界因素下(如轻微碰撞)容易出现倾倒的情况。因此，如何在有效降低显示屏的安装难度的同时避免显示屏倾倒已成为亟待解决的问题。
为了解决上述技术问题，请参照图1-图9所示，本申请的第一方面提出了一种用于显示设备的升降装置100，能够在有效降低显示屏的安装难度的同时避免显示屏倾倒。
升降装置100包括升降机构120以及支撑机构110，升降机构120与待升降部件130连接并用于调整待升降部件130的高度，支撑机构110与待升降部件130连接，且可相对于待升降部件130转动，并用于根据待升降部件130的高度调整对待升降部件130的支撑长度。
基于本申请实施例的一种用于显示设备的升降装置100，升降机构120与待升降部件130连接以对待升降部件130进行高度调节，以实现待升降部件130的水平安装，降低了待升降部件130的安装难度，同时支撑机构110与待升降部件130连接且可相对于待升降部件130 转动，待待升降部件130的高度调整好后，支撑机构110可根据待升降部件130的高度来调整对待升降部件130的支撑长度以对待升降部件130进行支撑，从而增强了待升降部件130放置在地面上的稳定性，以有效避免待升降部件130因高度调节过高而出现倾倒的现象。
请参照图1所示，图1为本申请一种实施例中的升降装置的结构示意图。
显示设备是一种可输出图像或触感信息(例如盲人设计的盲文显示器)的设备。根据输入显示设备的输入信号的不同，又可将显示设备划分为电子显示设备和机械显示设备，其中，电子显示设备的输入信号为电子信号。需要注意的是，显示设备可以但不仅限于显示屏。
待升降部件130可以理解成需要进行高度调整的显示设备，其可以但不仅限于显示屏。
升降机构120作为升降装置100中用于调整待升降部件130的高度的组件，升降机构120与待升降部件130连接并用于调整待升降部件130的高度，例如升降机构120可以驱动待升降部件130做直线运动，也可以驱动待升降部件130做曲线运动，来实现待升降部件130高度的调整，当然，升降机构120可以采用电动的方式驱动待升降部件130运动，也可以采用手动的方式驱动待升降部件130运动，关于升降机构120的结构以及升降机构120是如何调整待升降部件130的高度将在下文进行展开介绍。
支撑机构110作为升降装置100中用于支撑待升降部件130的组件，支撑机构110与待升降部件130连接且可相对于待升降部件130转动，支撑机构110可以独立支撑待升降部件130，例如支撑机构110的一端与待升降部件130连接，支撑机构110的另一端直接独立抵接于地面，以支撑待升降部件130，当然，支撑机构110也可以与升降机构120配合以共同支撑待升降部件130，例如支撑机构110的一端与待升降部件130连接，支撑机构110的另一端与升降机构120连接，以支撑待升降部件130。
支撑机构110用于根据待升降部件130的高度调整对待升降部件130的支撑长度，也就是说，升降机构120每将待升降部件130调整至一个高度位置上，支撑机构110都可以根据该高度位置来调整一个对应的支撑长度对待升降部件130进行支撑，也即支撑机构110对待升降部件130的支撑长度是根据升降机构120对待升降部件130的高度调整的变化而变化，需要注意的是，“支撑长度”可以理解成支撑机构110与待升降部件130之间的连接点同支撑机构110远离待升降部件130的端点之间的直线距离。
请参照图2-图7所示，图2为本申请一种实施例中的支撑机构的侧视图，图3为本申请一种实施例中的支撑机构的正视图，图4为本申请一种实施例中的待升降部件升高后支撑机构处于关闭状态时的结构示意图，图5为本申请一种实施例中的待升降部件升高后支撑机构处于关闭状态时的侧视图，图6为本申请一种实施例中的待升降部件升高后支撑机构处于打开状态时的结构示意图，图7为本申请一种实施例中的待升降部件升高后支撑机构处于打开 状态时的侧视图。
可以理解的是，支撑机构110除了对待升降部件130起支撑作用来增强待升降部件130的稳定性外，支撑机构110对待升降部件130的支撑长度还需要根据待升降部件130高度的调整而进行相应的改变，在一些实施例中，支撑机构110包括伸缩结构111，伸缩结构111与待升降部件130连接，且伸缩结构111通过做伸缩移动以调整支撑长度。该设计中，支撑机构110通过伸缩结构111做伸缩移动来调整对待升降部件130的支撑长度，降低了操作难度。
在一实施例中，考虑到能够通过伸缩移动实现长度调整的机械结构有很多，例如利用气缸的活塞杆做伸缩运动来实现长度调整，为降低伸缩结构111的调节难度，在一些实施例中，伸缩结构111包括第一伸缩杆1111、第二伸缩杆1112以及锁紧件1113，第二伸缩杆1112与待升降部件130连接，第二伸缩杆1112远离待升降部件130的一端套设于第一伸缩杆1111且可相对于第一伸缩杆1111滑动，以调整伸缩结构111对待升降部件130的支撑长度，锁紧件1113穿设于第一伸缩杆1111以及第二伸缩杆1112，以在伸缩结构111调整对待升降部件130的支撑长度后，锁紧第一伸缩杆1111以及第二伸缩杆1112。在一实施例中，第一伸缩杆1111的横截面呈矩形，且第二伸缩杆1112呈筒状结构且与第一伸缩杆1111相适配，第二伸缩杆1112滑动套设于第一伸缩杆1111外以与第一伸缩杆1111形成一个伸缩杆结构，通过滑动改变第二伸缩杆1112与第一伸缩杆1111之间的相对位置以实现伸缩结构111对待升降部件130的支撑长度的调整，锁紧件1113用于实现第一伸缩杆1111以及第二伸缩杆1112之间位置的相对固定，关于锁紧件1113的结构将在下文进行展开介绍，这里不做赘述。该设计中，第一伸缩杆1111以及第二伸缩杆1112相互滑动套接形成一个伸缩杆结构，通过改变第一伸缩杆1111与第二伸缩杆1112之间的相对位置来调节伸缩结构111对待升降部件130的支撑长度，并通过锁紧件1113对调整后的第一伸缩杆1111以及第二伸缩杆1112之间的相对位置进行锁紧固定，降低了伸缩结构111的调节难度。
请继续参照图2-图7所示，在一实施例中，可以理解的是，升降机构120对待升降部件130的高度调节具有不确定性，也即升降机构120可以将待升降部件130调整到介于其调整范围内的任一高度位置上，换言之，升降机构120对待升降部件130的高度调节是一种连续性的调节，为使伸缩结构111对待升降部件130的支撑长度的调整能够适应升降机构120对待升降部件130的连续性高度调节，以增强伸缩结构111的适用性，在一些实施例中，第二伸缩杆1112具有沿其长度方向设置的调节槽11121，锁紧件1113依次穿设调节槽11121以及第一伸缩杆1111的活动端11111，其中，活动端11111为第一伸缩杆1111靠近第二伸缩杆1112的一端。在一实施例中，调节槽11121位于第二伸缩杆1112的靠近第一伸缩杆1111 的一端，且调节槽11121沿垂直于第二伸缩杆1112的轴向贯穿第二伸缩杆1112，调节槽11121沿平行于第二伸缩杆1112的轴向上的长度尺寸决定了第二伸缩杆1112能够相对于第一伸缩杆1111移动的距离，且该距离即为伸缩结构111对待升降部件130的支撑长度的调整范围。该设计中，通过调节槽11121的设计，实现了第二伸缩杆1112与第一伸缩杆1111之间位置的无级调节来配合升降机构120对待升降部件130的高度调整，从而增强了伸缩结构111的适用性。
在一实施例中，考虑到能够实现第一伸缩杆1111与第二伸缩杆1112之间位置相对固定的锁紧件1113的结构有很多，例如第一伸缩杆1111与第二伸缩杆1112之间通过卡接配合的方式来实现两者之间位置的相对固定，在一实施例中，锁紧件1113包括设置于第一伸缩杆1111以及第二伸缩杆1112中的一个上的卡块，锁紧件1113还包括设置于第一伸缩杆1111以及第二伸缩杆1112中的另一个上的卡槽，第一伸缩杆1111以及第二伸缩杆1112通过卡块与卡槽之间的卡接配合来实现位置的相对固定。为配合第一锁紧杆11131以及第二锁紧杆11131之间的无级调节，以增强伸缩结构111的适用性，在一些实施例中，锁紧件1113包括锁紧块11132以及锁紧杆11131，锁紧杆11131依次穿设于第二伸缩杆1112以及第一伸缩杆1111并伸出第二伸缩杆1112外，锁紧块11132与锁紧杆11131的伸缩第二伸缩杆1112外的一端螺纹连接。该设计中，锁紧块11132与锁紧杆11131螺纹连接，待第一伸缩杆1111以及第二伸缩杆1112之间的相对位置调整好后，转动锁紧块11132，锁紧块11132沿锁紧杆11131朝靠近第二伸缩杆1112的方向运动，直至锁紧块11132运动至与第二伸缩杆1112的外表面抵紧，从而实现第一伸缩杆1111以及第二伸缩杆1112之间位置的相对固定。
可以理解的是，伸缩结构111可以与待升降部件130直接连接，也可以借助某中间连接结构件与待升降部件130间接连接，在一些实施例中，支撑机构110还包括第一连接座112以及第二连接座113，第一连接座112与第一伸缩杆1111远离第二伸缩杆1112的一端铰接，且与升降机构120固定连接，第二连接座113与第二伸缩杆1112远离第一伸缩杆1111的一端铰接，且与待升降部件130固定连接，也就是说，伸缩结构111通过第一连接座112以及第二连接座113分别与升降机构120以及待升降部件130间接连接。该设计中，第一连接座112相当于第一伸缩杆1111与升降机构120之间的中间连接结构件，第二连接座113相当于第二伸缩杆1112与待升降部件130之间的中间连接结构件，通过第一连接座112以及第二连接座113的设置，降低了支撑机构110与待升降部件130以及升降机构120之间的安装难度；且第一连接座112与第一伸缩杆1111铰接并与升降机构120固定连接，第二连接座113与第二伸缩杆1112铰接并与待升降部件130固定连接，使得待升降部件130、升降机构120以及支撑机构110之间形成一个三角形结构，进一步加强了该升降装置100对待升降部件130的 支撑稳定性。
请参照图8-图9所示，图8为本申请一种实施例中待升降部件与升降装置连接后的剖面结构示意图，图9为图8中A处的放大示意图。
考虑到能够对待升降部件130的高度进行调整的升降机构120的机械结构有很多，例如升降机构120包括升降电机，升降电机与待升降部件130连接以驱动待升降部件130做升降移动。为配合支撑机构110对待升降部件130的支撑长度的调整，在一些实施例中，升降机构120包括支撑架、丝杆122以及传动元件123。
支撑架作为升降机构120中的底座121，其用于支撑和承载升降机构120中的其他部件。支撑架可以是一个单独的板状结构，也可以是几根支杆拼接而成的架体结构。在本实施例中，支撑架为长条形板状结构，且上述第一连接座112通过螺钉实现与支撑架之间的固定连接。
丝杆122作为升降机构120中的其中一个传动元件123，其用于部件间的动力传递。丝杆122与支撑架连接，在一实施例中，丝杆122与支撑架固定连接，例如丝杆122的一端可以通过焊接的方式实现与支撑架之间的固定连接，需要说明的是，这里丝杆122固定在支撑架上，也就是说，丝杆122与支撑架形成一个整体，丝杆122相对于支撑件不会产生任何形式的运动。
传动元件123作为升降机构120中的又一传动元件123，其用于部件间的动力传递。传动元件123套设于丝杆122且与待升降部件130连接，在一实施例中，传动元件123与丝杆122螺纹连接，传动元件123与丝杆122之间存在机械传动，由于丝杆122固定连接于支撑架，故传动元件123与丝杆122之间的机械传动的表现形式为传动元件123沿丝杆122的轴线方向做往复运动。
传动元件123可沿丝杆122的轴线方向做往复运动，进而带动待升降部件130做升降移动，也就是说，传动元件123在动力的作用下沿丝杆122的轴线方向朝靠近或远离支撑架的方向运动，传动元件123与待升降部件130连接，从而带动待升降部件130跟随传动元件123沿丝杆122的轴线方向做升降移动，进而调整待升降部件130的高度。在一实施例中，传动元件123包括与丝杆122螺纹连接的螺纹套管，安装人员可以借助扳手等工具直接转动螺纹套管，使螺纹套管沿丝杆122的轴线方向运动从而带动待升降部件130做升降移动，当然，传动元件123还可以包括与螺纹套管啮合连接的齿轮，齿轮与电机的主轴同轴固定连接，电机安装在待升降部件130的壳体上，电机转动带动齿轮转动，齿轮转动带动与之啮合的螺纹套管一边绕丝杆122的周向转动一边沿丝杆122的轴线方向运动，从而带动待升降部件130做升降移动。该设计中，传动元件123沿丝杆122的轴线方向做往复运动，传动元件123与待升降部件130连接，从而带动待升降部件130跟随传动元件123沿丝杆122的轴线方向做 升降移动，进而调整待升降部件130的高度。
请继续参照图8-图9所示，在一实施例中，考虑到传动元件123可以直接与待升降部件130连接，例如传动元件123可以通过焊接的方式直接与待升降部件130固定连接，在一些实施例中，升降机构120还包括连接件124，传动元件123通过连接件124与待升降部件130连接，也就是说，连接件124的设置实现了传动元件123与待升降部件130之间的间接连接。该设计中，连接件124的设置降低了待升降部件130的安装难度。
在一实施例中，考虑到连接件124作为连接传动元件123与待升降部件130的中间连接部件，连接件124可以采用卡接配合的方式来实现传动元件123与待升降部件130之间的连接。可以理解的是，传动元件123在沿丝杆122的轴线方向做往复运动的过程中，连接件124的一端与传动元件123连接，使得连接件124在传动元件123的作用下沿丝杆122的轴线方向做往复运动，连接件124的另一端与待升降部件130连接，使得待升降部件130在连接件124的作用下沿丝杆122的轴线方向做升降移动，在一些实施例中，连接件124为平面轴承，平面轴承包括第一轴承环1241、第二轴承环1242以及设置于第一轴承环1241以及第二轴承环1242之间的多个(两个及两个以上)滚珠1243，其中，第一轴承环1241以及第二轴承环1242中的一个与传动元件123连接，第一轴承环1241以及第二轴承环1242中的另一与待升降部件130连接。在一实施例中，第一轴承环1241与传动元件123抵接，第二轴承环1242与待升降部件130抵接。该设计中，传动元件123连接第一轴承环1241，待升降部件130对应的连接第二轴承环1242，第一轴承环1241与第二轴承环1242之间通过滚珠1243连接，故传动元件123带动待升降部件130沿丝杆122的轴线方向做升降移动的过程中，连接件124将传动元件123与待升降部件130之间的滑动摩擦转变成滚动摩擦，减小了传动元件123与待升降部件130之间的摩擦力，使得待升降部件130沿丝杆122的轴线方向上的移动更加顺畅，同时还延长了第一传动元件123与待升降部件130的使用寿命。
本申请的第二方面提出了一种显示设备，该显示设备包括上述的待升降部件130以及上述的升降装置100，且待升降部件130为显示屏。
基于本申请实施例中的显示设备，具有上述升降装置100的显示设备，通过升降机构120来调整显示屏的高度，并针对显示屏的不同高度来调整支撑机构110的支撑长度来对显示屏进行支撑，从而在降低显示设备的安装难度的同时增强了显示设备放置在地面上的稳定性。
