为了说明本申请所提供的技术方案，以下结合具体附图及实施例进行详细说明。
请参阅图1、图2、图3，本申请的一些实施例提供一种顶出装置100，设于箱体200以及盖合箱体200的待拆结构300之间，且用于顶出待拆结构300，顶出装置100包括顶出件110和驱动磁铁120，其中，顶出件110能够绕转动轴线转动，顶出件110包括分设于转动轴线相对两侧的顶推部111和联动部112，顶推部111用于顶推待拆结构300；驱动磁铁120设于联动部112靠近待拆结构300的一侧，在外部磁铁靠近驱动磁铁120时，驱动磁铁120能够在斥力作用下带动联动部112朝远离待拆结构300的方向转动，而使顶推部111朝靠近待拆结构300的方向转动。
具体地，基于本实施例的结构，在无需拆卸待拆结构300时，顶出装置100可容纳于箱体200和盖合箱体200的待拆结构300之间，且相对于箱体200固定；而在需要将待拆结构300从箱体200上拆卸下来时，操作人员可握持外部磁铁并从待拆结构300的外侧靠近驱动磁铁120，随后，外部磁铁和驱动磁铁120之间的互斥力，可使得驱动磁铁120朝远离待拆结构300的方向移动，而实现带动联动部112绕转动轴线朝远离待拆结构300的方向转动；又由于顶推部111相对于联动部112设于转动轴线的另一侧且与联动部112同步转动，从而可通过联动部112的转动带动顶推部111同步绕转动轴线朝靠近待拆结构300的方向转动，实现将原本盖合于箱体200的待拆结构300顶出。
因而，本申请实施例提供的顶出装置100，可利用外部磁铁与其驱动磁铁120产生互斥力，而带动联动部112朝远离待拆结构300的方向转动，并同时带动顶推部111朝靠近待拆结构300的方向转动，从而实现将原本盖合于箱体200的待拆结构300顶出。因而，该顶出装置100可轻松、便利地实现待拆结构300的拆卸，操作简便，拆卸效率高，可便于维护、维修作业的展开，且其仅需借助外部磁铁而无需定制额外的系统，从而成本较低，整体使用性能较佳。
请参阅图1、图2、图3，在本实施例中，顶推部111和联动部112均为杆状结构，且顶推部111和联动部112之间形成夹角。
通过采用上述方案，可便于对顶推部111和联动部112的长度、截面形状、截面尺寸、夹角的角度等参数进行设计，设计难度相对较低，且加工便利性相对较高，从而利于保障顶推部111和联动部112的结构强度和使用性能，尤其利于对顶推部111顶出待拆结构300的功能进行保障。
请参阅图1、图2、图3，在本实施例中，顶推部111和联动部112之间所形成的夹角为钝角。
通过采用上述方案，在顶推部111的初始位置相同的情况下，可于联动部112靠近待拆结构300的一侧留置相对充足的空间，以便于容纳相对较厚的驱动磁铁120，从而可保障并提高驱动磁铁120的使用性能。
请参阅图1、图2、图3，在本实施例中，顶出装置100还包括顶出基座130、磁铁基座140和弹性件150，其中，顶出基座130于其靠近待拆结构300的一侧开设有第一滑动孔131，且于其靠近顶出件110的一侧开设有与第一滑动孔131连通的第一穿接槽132；磁铁基座140于其靠近待拆结构300的一侧开设有用于容纳驱动磁铁120的容纳槽141，磁铁基座140滑动连接于第一滑动孔131；弹性件150弹性抵持于磁铁基座140远离待拆结构300的一侧和顶出基座130之间；其中，联动部112穿设于第一穿接槽132，且与磁铁基座140远离待拆结构300的一侧抵接。
具体地，基于本实施例的结构，在无需拆卸待拆结构300时，顶出装置100整体能够稳定地容纳于箱体200和盖合箱体200的待拆结构300之间，且顶出基座130相对于箱体200固定，同时，弹性件150弹性抵持着磁铁基座140，并使磁铁基座140和容纳于容纳槽141的驱动磁铁120稳定于靠近待拆结构300的位置，以便于后续外部磁铁轻松实现与驱动磁铁120互斥；而联动部112则维持着抵接磁铁基座140远离待拆结构300的一侧的状态，且顶推部111维持着与待拆结构300间隔的状态。
而在需要将待拆结构300从箱体200上拆卸下来时，操作人员可握持外部磁铁并从待拆结构300的外侧靠近待拆结构300附近的驱动磁铁120，随后，外部磁铁能够轻松、可靠地与驱动磁铁120相互产生互斥力，在斥力作用下，驱动磁铁120可带动磁铁基座140于第一滑动孔131内朝远离待拆结构300的方向滑动，从而可带动与磁铁基座140抵接的联动部112朝远离待拆结构300的方向转动，从而实现带动顶推部111同步朝靠近待拆结构300的方向转动，实现将原本盖合于箱体200的待拆结构300顶出。
其中，第一滑动孔131的延伸方向限制了驱动磁铁120和磁铁基座140的移动方向，且第一滑动孔131的延伸长度限制了驱动磁铁120和磁铁基座140的移动范围，从而可保障驱动磁铁120的使用性能，保障驱动磁铁120能够可靠发挥其效用。
其中，联动部112保持穿设于第一穿接槽132，即仅能够于第一穿接槽132的范围内转动，如此，可限制联动部112脱离驱动磁铁120，从而可保障联动部112与驱动磁铁120之间的联动性。
其中，在外部磁铁远离驱动磁铁120且互斥力削弱、消失时，驱动磁铁120和磁铁基座140可在弹性件150的弹力下自动复位，以便于操作人员在维护、维修待拆结构300后将待拆结构300重新盖合于箱体200。
可选地，弹性件150弹性抵持于磁铁基座140远离待拆结构300的一侧和第一滑动孔131的孔底之间。
因而，通过采用上述方案，可提高顶出装置100的使用性能，保障顶出装置100的使用可靠性。
请参阅图1、图2、图3，在本实施例中，顶出装置100还包括止挡盖160，止挡盖160设于第一滑动孔131的孔口侧，且用于限制磁铁基座140脱离第一滑动孔131。
通过采用上述方案，可通过止挡盖160限制磁铁基座140从第一滑动孔131的孔口脱出，从而可保障磁铁基座140与第一滑动孔131的滑接可靠性；此外，还可通过止挡盖160形成磁铁基座140在弹性件150的弹力作用下复位时的定位基准；从而可提高顶出装置100的使用性能。
请参阅图1、图2、图3，在本实施例中，止挡盖160呈环状设置。
通过采用上述方案，可降低止挡盖160对驱动磁铁120与外部磁铁之间的斥力的影响程度，从而可保障驱动磁铁120的使用性能，提高驱动磁铁120的可靠性。
请参阅图1、图2、图3，在本实施例中，止挡盖160的内环的截面尺寸等于或大于容纳槽141的截面尺寸。
通过采用上述方案，可在保障止挡盖160对磁铁基座140的止挡效用的基础上，使驱动磁铁120在初始位置能够一部分容纳于容纳槽141，且另一部分容纳于止挡盖160的内环处，而实现相对靠近待拆结构300，从而可便于后续外部磁铁能够轻松、可靠地与驱动磁铁120实现互斥，从而可提高驱动磁铁120的使用性能，提高驱动磁铁120的使用可靠性。
请参阅图1、图2、图3，在本实施例中，顶出基座130还于第一滑动孔131的孔底开设有第二滑动孔133，第二滑动孔133的孔径小于第一滑动孔131的孔径，顶出装置100还包括支撑基座170，支撑基座170固定连接于磁铁基座140远离待拆结构300的一侧，且滑动连接于第二滑动孔133，支撑基座170于其周侧开设有与第一穿接槽132连通的第二穿接槽171；其中，联动部112穿设于第一穿接槽132和第二穿接槽171，且与磁铁基座140远离待拆结构300的一侧抵接。
具体地，在磁铁基座140于第一滑动孔131内往复滑动时，支撑基座170将同步于第二滑动孔133内往复滑动，基于此，可在一定程度上提高磁铁基座140和支撑基座170整体的移动平稳性，从而可保障顶出件110的转动平稳性，利于减少顶出件110的震动情况，从而可减少顶出件110对待拆结构300的损伤风险，可提高顶出装置100的使用性能。
请参阅图1、图2、图3，在本实施例中，支撑基座170的周侧凸设有抵持环172，弹性件150弹性抵持于抵持环172和第一滑动孔131的孔底之间。
通过采用上述方案，可在外部磁铁远离驱动磁铁120且互斥力削弱、消失时，通过弹性件150的弹力，可靠实现驱动磁铁120、磁铁基座140和支撑基座170的复位，以便于操作人员在维护、维修待拆结构300后将待拆结构300重新盖合于箱体200；还可通过弹性件150的弹力平衡抵持环172的状态，而实现提高磁铁基座140和支撑基座170移动过程中的平稳性；从而可提高顶出装置100的使用性能。
请参阅图1、图2、图3，在本实施例中，弹性件150套接于支撑基座170的周侧。
通过采用上述方案，可在上一实施例的基础上，平衡、均衡驱动磁铁120、磁铁基座140、支撑基座170和抵持环172在周向上的受力情况，从而可提高驱动磁铁120、磁铁基座140、支撑基座170和抵持环172在移动过程中的平稳性，可提高顶出装置100的使用性能。
请参阅图1、图2、图3，在本实施例中，弹性件150弹性抵持于支撑基座170和第二滑动孔133的孔底之间。
通过采用上述方案，可在外部磁铁远离驱动磁铁120且互斥力削弱、消失时，通过弹性件150的弹力，可靠实现驱动磁铁120、磁铁基座140和支撑基座170的复位，以便于操作人员在维护、维修待拆结构300后将待拆结构300重新盖合于箱体200。
请参阅图1、图2、图3，在本实施例中，支撑基座170呈筒状。
通过采用上述方案，可利于削弱弹性件150使驱动磁铁120、磁铁基座140、支撑基座170和抵持环172实现复位时所需的弹力大小，从而可提高顶出装置100的使用性能。
请参阅图1、图2、图3，在本实施例中，顶出装置100还包括转动座180和转动轴190，转动座180设有两个，两转动座180相对设置，且固定连接于顶出基座130；转动轴190连接于两转动座180之间，且与顶出件110套接配合。
通过采用上述方案，可通过两转动座180共同支撑转动轴190，并使顶出件110转动连接于转动轴190，基于此，可提高顶出装置100整体的装配便利性，且提高顶出件110的转动平稳性，从而可保障顶出件110的顶推效果，保障顶出装置100的使用性能。
请参阅图1、图2、图3，本申请的一些实施例还提供一种LED显示屏，包括箱体200以及盖合箱体200的显示模组，还包括至少一个顶出装置100，待拆结构300为显示模组。
本申请实施例提供的LED显示屏，可通过顶出装置100便利、可靠地将显示模组从箱体200上顶出，操作简便，拆卸效率高，可便于显示模组的维护、维修作业的展开，且其仅需借助外部磁铁而无需定制额外的系统，从而成本较低，且该顶出装置100基本不会损坏显示模组，尤其不会损坏显示模组的灯板，从而整体使用性能较佳。
请参阅图1、图2、图3，在本实施例中，顶出装置100相对于箱体200固定。
通过采用上述方案，可在无需拆卸显示模组时，使顶出装置100相对于箱体200固定，而将LED显示屏作为整体进行存储、转运、销售、使用；而在需要拆卸显示模组时，再通过相对于箱体200固定的顶出装置100便利、可靠地将显示模组从箱体200上拆卸下来，以便于展开显示模组的维护、维修作业。
