本申请的边角保护装置属于LED显示屏技术领域，LED显示屏越来越向高端方向发展，市场上显示屏产品趋于轻、薄，尤其在租赁屏市场，由于不同场所的应用，要不断的拆卸和运输。在拆卸运输的过程中，显示屏很容易发生磕碰，对于LED显示屏产品来说，最容易损坏的是四个角的LED模组，显示屏角上的LED模组损坏，造成整个屏幕出现死点现象。
如图1至图23所示，根据本申请的第一方面，本申请提供了一种边角保护装置，运用于LED显示屏，其中，LED显示屏由多个LED显示屏单元箱体拼接而成，每个LED显示屏单元箱体均包括显示屏箱体200和显示模块300。在本实施方式中，边角保护装置包括底座10、保护块20和传动组件30，底座10安装在显示屏箱体200上，保护块20可活动安装在底座10上，传动组件30包括第一驱动件31、第二驱动件32和传动件33，其中，第一驱动件31和第二驱动件32均与传动件33传动连接，传动件33与保护块20传动连接，用于带动保护块20伸出或缩回底座10，避免显示屏箱体200上的显示模块300在运输过程或拆装过程中被磕坏。
具体的，保护块20呈L型结构，第一驱动件31和第二驱动件32分别设置在底座10相邻的两个侧面上，当两个LED显示屏单元箱体拼接时，第一驱动件31和第二驱动件32通过与底座10的侧面抵接后，驱动传动件33带动保护块20伸出或缩回底座10，从而可以更好的保护显示屏箱体200上的显示模块 300。
应当说明的是，底座10的形状与显示屏箱体200边角的形状相匹配，以确保保护块20能够同时保护显示模块300相交的两个侧面和两个侧面形成的夹角。
此外，传动组件30的传动方式可以为螺纹传动，传动组件30的传动方式也可以为凸轮传动，或者传动组件30的传动方式也可以为杠杆传动，甚至传动组件30的传动方式还可以为皮带传动、链传动、齿轮传动等等，本申请不加以限制，其目的只要能够通过第一驱动件31和第二驱动件32驱动传动件33带动带动保护块20伸出或缩回底座10即可。
在一个可选的实施方式中，底座10包括固定座11和支撑座12，其中，支撑座12安装在固定座12上，第一驱动件31和第二驱动件32均安装在固定座11，传动件33设置在固定座11与支撑座12之间，采用以上技术方案后，不仅可以使得整个边角保护装置的结构更为紧凑，而且也便于将传动件33安装在上，同时也便于固定座11和支撑座12的成型，简化了底座10的成型工艺，节约了大量的制造成本。
在一个可选的实施方式中，底座10上设有弧形轨迹槽122，保护块20的两侧面上连接有活动杆22，其中，活动杆22可活动安装于轨迹槽122中，以使得保护块20能够在传动件33的带动下沿轨迹槽122移动。
具体的，轨迹槽122的数量为两个，两个轨迹槽122设置在支撑座12，保护块20上设有与轨迹槽122数量匹配的活动杆22，两个活动杆22均可活动安装于轨迹槽122中，以确保保护块20沿沿轨迹槽122移动时的平稳性。
在一个可选的实施方式中，轨迹槽122包括第一轨迹槽1221和第二轨迹槽1222，第一轨迹槽1221沿底座10的竖直方向设置，第二轨迹槽1222与第一轨迹槽1221呈倾斜夹角设置，以使得保护块20具有相对底座10的纵向位移，同时又有相对底座10的横向位移。
具体的，第一轨迹槽1221和第二轨迹槽1222之间的夹角在100至150度之间，第一轨迹槽1221和第二轨迹槽1222的连接处采用光滑圆角过渡，且第一轨迹槽1221和第二轨迹槽1222的宽度均与活动杆22的直径相适配。当第一驱动件31和第二驱动件32驱动传动件33带动保护块20移动时，保护块20通过活动杆22先沿着第一轨迹槽1221向下移动；当活动杆22位移第一轨迹槽1221 和第二轨迹槽1222的连接处时，第一驱动件31和第二驱动件32继续驱动传动件33带动保护块20移动，此时活动杆22沿第二轨迹槽1222移动，即相当于底座10的横向移动，以使得保护块20能缩回底座10中，确保两个LED显示屏单元箱体拼接时不会因为保护块20的凸起而产生间隙。
在一个可选的实施方式中，第一驱动件31包括第一螺纹轴311，第二驱动件32包括第二螺纹轴321，传动件33包括传动轴331，其中，第一螺纹轴311和第二螺纹轴321均与传动轴331传动连接。
具体的，第一驱动件31通过第一螺纹轴311与传动轴331传动连接，第二驱动件32通过第二螺纹轴321与传动轴331传动连接，当两个LED显示屏单元箱体拼接时，第一驱动件31抵接在底座10与其相对的侧面上，通过两个LED显示屏单元箱体的挤压，第一驱动件31能够相对底座10移动，从而可以使得第一驱动件31能够通过第一螺纹轴311控制传动轴331带动保护块20移动沿第一轨迹槽1221和第二轨迹槽1222移动；以此同时，第二驱动件32能够相对底座10移动，从而可以使得第二驱动件32能够通过第二螺纹轴321控制传动轴331带动保护块20移动沿第一轨迹槽1221和第二轨迹槽1222移动，从而可以实现保护块20缩回底座10的效果，反之解除两个LED显示屏单元箱体之间挤压，即两个LED显示屏单元箱体拆装时，保护块20恢复伸出状态，以实现保护LED显示屏单元箱体的作用。
在一个可选的实施方式中，传动件33包括与保护块20传动连接的滑块332，在本实施方式中，传动轴331上设有螺旋齿3312和与第一螺纹轴311及第二螺纹轴321配合的直齿3311，其中，滑块332上设有螺旋齿槽3321，螺旋齿3312与螺旋齿槽3321传动连接。当第一螺纹轴311和/或第二螺纹轴321驱动直齿3311带动螺旋齿3312转动时，由于螺旋齿3312与螺旋齿槽3321传动连接，因此滑块332会沿着传动轴331的轴线方向移动，从而带动保护块20在传动轴331的轴线方向上下移动，而保护块20通过活动杆22限制在第一轨迹槽1221和第二轨迹槽1222内活动，即保护块20在滑块332驱动下能够在第一轨迹槽1221和第二轨迹槽1222内活动，从而可以实现保护块20缩回或伸出底座10的效果，已达到保护显示屏箱体200边角的作用。
在一个可选的实施方式中，滑块332上设有活动轴3322，其中，保护块20上设有活动槽21，活动轴3322与活动槽21配合，以使得传动轴331能够通过 滑块332驱动保护块20沿轨迹槽122移动。
具体的，滑块332在移动时，由于活动杆22可活动于第一轨迹槽1221和第二轨迹槽1222内，因此，滑块332沿传动轴331的轴线方向移动时，活动轴3322能够相对活动槽21左右移动，避免活动轴3322、活动槽21、活动杆22和轨迹槽122之间因为过约束而导致保护块20无法在底座10上具有纵向和横向两个方向上位移。
在一个可选的实施方式中，支撑座12上设有轴承安装孔125，其中，传动组件30还包括轴承件34。在本实施方式中，传动轴331靠近螺旋齿3312的一端通过轴承件34可转动安装在轴承安装孔125，传动轴331的另一端穿过固定座11与第一驱动件31及第二驱动件32传动连接。
具体的，传动轴331在螺旋齿3312与直齿3311之间设有第二轴承部3314，传动轴331在远离直齿3311的一端设有第一轴承部3313，第一轴承部3313通过轴承件34可转动安装在轴承安装孔125，第二轴承部3314可转动安装在固定座11中，这样不仅可以方便传动轴331的加工，同时也可以确保传动轴331在传动过程中受力的稳定性，从而提高了传动轴331的使用寿命。
在一个可选的实施方式中，第一驱动件31还包括第一弹性件312，固定座11上设有用于安装第一螺纹轴311的第一安装槽111，当第一螺纹轴311和第一弹性件312均安装在第一安装槽111时，第一弹性件312的一端与第一螺纹轴311抵接，第一弹性件312的另一端抵接在第一安装槽111的底端上，这样可以确保第一螺纹轴311始终在第一弹性件312的弹力作用下伸出于固定座11，从而确保了保护块20能够在第一螺纹轴311的作用下始终处于保护着LED显示屏单元箱体的边角，当两个LED显示屏单元箱体需要拼接时，由于第一螺纹轴311受挤压而使得保护块20缩回底座，以便两个LED显示屏单元箱体的拼接。
和/或，第二驱动件32还包括第二弹性件322，固定座11上设有用于安装第二螺纹轴321的第二安装槽112，当第二螺纹轴321和第二弹性件322均安装在第一安装槽112时，第二弹性件322的一端与第二螺纹轴321抵接，第二弹性件322的另一端抵接在第二安装槽112的底端上，这样可以确保第二螺纹轴321始终在第二弹性件322的弹力作用下伸出于固定座11，从而确保了保护块20能够在第二螺纹轴321的作用下始终处于保护着LED显示屏单元箱体的边 角，当两个LED显示屏单元箱体需要拼接时，由于第二螺纹轴321受挤压而使得保护块20缩回底座，以便两个LED显示屏单元箱体的拼接。
在一个可选的实施方式中，第一安装槽111与所述第二安装槽112呈90度夹角设置，且第一安装槽111设置在第二安装槽112的下方。在本实施方式中，第一安装槽111与所述第二安装槽112之间的距离与第一螺纹轴311或第二螺纹轴321的直径相适配，以使得两个LED显示屏单元箱体的拼接时，第一螺纹轴311和第二螺纹轴321能够同时作用在底座10与其相对的侧面上，以使得第一螺纹轴311能够控制其对应的保护块20缩回底座10中，第二螺纹轴321通过能够控制其对应的保护块20缩回底座10中，以便两个LED显示屏单元箱体能够顺利完成拼接。
在一个可选的实施方式中，支撑座12与保护块20接触的两侧面呈90度夹角设置，且支撑座12与保护块20接触的两侧面到固定座11与其相对的两侧面距离与保护块20的厚度相适配。在本实施方式中，支撑座12与保护块20接触的两侧面分别为第一侧面123和第二侧面124，第一侧面123和第二侧面124之间的夹角与保护块20均为90度，以确保保护块20能够缩回固定座11中，避免保护块20的凸出而影响到两个LED显示屏单元箱体的拼接。
在一个可选的实施方式中，保护块20还包括第一延伸面23和第二延伸面24，其中，第一延伸面23和第二延伸面24分别固定在保护块20的两侧面上，在本实施方式中，传动件33与第一延伸面23和第二延伸面24传动连接。
具体的，活动槽21和活动杆22均设置在第一延伸面23和第二延伸面24上，第一延伸面23与第二延伸面24之间的距离与支撑座12与其相对的两侧面距离相匹配，以使得保护块20能够在活动轴3322的驱动下，保护块20在活动杆22作用下沿着轨迹槽122移动，采用以上技术方案后，不仅能够确保保护块20上有足够的位置设计活动槽21和安装活动杆22，同时也可以确保保护块20能够更加稳定的在支撑座12上移动。
在一个可选的实施方式中，支撑座12的中部设有容纳槽121，其中，传动件33的一端可转动安装于固定座11上，传动件33的另一端可转动安装在容纳槽121的底部。
具体的，固定座11上设有第一柱体114和第二柱体115，其中，第一柱体114和第二柱体115之间设置有传动件安装孔113和支撑座固定部116，支撑座 12上设有支撑座安装部126，支撑座12通过支撑座安装部126安装在支撑座固定部116上，传动件33的一端可转动安装于传动件安装孔113中，传动件33的另一端通过轴承件34可转动安装在轴承安装孔125。
当两个LED显示屏单元箱体拼接时，两个LED显示屏单元箱体上的显示屏箱体200分别为第一显示屏箱体201和第二显示屏箱体202，第一显示屏箱体201和第二显示屏箱体202上均安装有边角保护装置100，当第一显示屏箱体201靠近第二显示屏箱体202时，第一显示屏箱体201上的第一驱动件31与第二显示屏箱体202上的底座挤压，第二显示屏箱体202上的第二驱动件32与第一显示屏箱体201上的底座挤压，使得第一驱动件31能够带动第一显示屏箱体201上的保护块20缩回底座中，第二驱动件32能够带动第二显示屏箱体202上的保护块20缩回底座中，从而使得第一显示屏箱体201能够紧贴在第二显示屏箱体202的侧壁上，以便完成LED显示屏单元箱体拼接。
当两个LED显示屏单元箱体解除拼接时，第一显示屏箱体201慢慢远离第二显示屏箱体202，第二显示屏箱体202上的底座解除对第一显示屏箱体201上的第一驱动件31挤压，第一驱动件31在第一弹性件312的作用下进行复位，从而带动保护块20伸出底座，起到保护第一显示屏箱体201上显示模块的边角作用。第一显示屏箱体201上的底座解除对第二显示屏箱体202上的第二驱动件32的挤压，第二驱动件32在第二弹性件322的作用下进行复位，从而带动保护块20伸出底座，起到保护第二显示屏箱体202上显示模块的边角作用。
应当说明的是，由于滑块332上设有螺旋齿槽3321，传动轴331上设有螺旋齿3312，螺旋齿3312与螺旋齿槽3321传动连接，因此保护块20的伸出或缩回只能通过传动轴331进行控制，而保护块20无法控制传动轴331的转动，从而使得保护块20对LED显示屏单元箱体的边角保护更加可靠安全。
根据本申请的第二方面，本申请还提供了一种LED显示屏，包括LED显示屏单元箱体和上述的边角保护装置100，其中，边角保护装置100安装在LED显示屏单元箱体的边角部。
