请参阅图2，电池组件40包括电池组42和电池保护座41，电池组42嵌设于电池保护座41中；电池保护座41固定于电池腔中，并锁紧于底盖13上。电池保护座41包括上保护盖411和下保护盖412，下保护盖412底部周边延展设置若干锁紧凸台4121，紧固件通过锁紧凸台4121将下保护盖412锁紧于底盖13上。进一步地，底盖13上设置若干凸出的卡位132，下保护盖412嵌设于若干卡位132围成范围的内部，起到快速定位的作用，可以避免因为下保护盖412相对于底盖13错动，对锁紧紧固件造成困难。同样地，支撑板31位于电池腔的一面设置若干卡位，上保护盖411嵌设于若干卡位围成的范围内内部，防止在搬运过程中移动电源倾斜，电池组42由于重力作用相对于支撑板31发生错位。
下保护盖412在角落位置设置有突出于底面的若干护角4122；电池组42嵌设于若干护角4122围合的范围内。此外，下保护盖412底部周边设置若干突出于底面的第四定位柱4123，上保护盖411对应地锁紧于若干第四定位柱4123上。可以理解的是，为了避免若干护角4122和第四定位柱4123长度过长，在注塑和组装过程中容易折断，上保护盖411对称设置有若干护角4122和第五定位柱4111；通过通过紧固件将第五定位柱4111锁紧于第四定位柱4123上。
电池组件40还包括若干PCBA，比如降压PCBA、BMS-PCBA以及MPPT-PCBA。在一 些实施例中，直接将若干PCBA分类锁紧于上保护盖411和下保护盖412一侧的定位柱上，如此，简化了移动电源的内部结构，能有效提高组装效率。可以理解的是，控制或者连接若干PCBA的插座及开关设置于电池腔近PCBA的侧壁上，可以减短接线长度，提高组装效率。
在一些实施例中，壳体10内部设置有若干支撑架17，该若干支撑架17设置于驱动腔或者电池腔内。支撑架17的顶部抵接腔体的顶面，支撑来自于腔体顶面的压力，防止腔体的顶面收到外部压力发生形变或者破损，对驱动组件50和电池组件40造成挤压或者损毁。
请参阅图2-4，在一些实施例中，中框12两侧面分别开设有对称设置的第一手持孔124，用于作业人员徒手搬运。优选地，两个第一手持孔124设置于中框12近顶盖11的一端。进一步地，顶盖11在近第一手持孔124的端部开设第二手持孔112；顶盖11的侧壁过渡衔接第一手持孔124和第二手持孔112相近的一侧，形成抓握部，便于人手抓握。对比于传统的外置提手，更有利于包装运输；并且能避免因提手外置所导致的装配不牢固等缺陷。
进一步地，在一些实施例中，壳体10还包括提手盖16。提手盖16的一端卡设于顶盖11，另一端固接于中框12的内侧壁。该提手盖16中部向腔体内部凹陷，该凹陷处的外周形状跟与之适配的第一手持孔124以及第二手持孔112的形状一致，用于衔接第一手持孔124和第二手持孔112相互远离的一侧。如此，以此形成更舒适的抓握空间，可以提高使用者的体验感。
请参阅图2、图5和图6，在一些实施例中，移动组件20包括带滚轮的伸缩拉杆21，伸缩拉杆21设置于所述移动电源与面板14的对侧，从顶盖11垂直插入壳体10中，并固接于壳体10，以便能更方便地移动该移动电源。伸缩拉杆21包括拉杆把手211、垂直连接于拉杆把手211两侧的两条竖杆212、垂直插设于竖杆212端部的横杆213，以及设置于横杆213两端的滚轮214。
具体地，顶盖11在所述伸缩拉杆21的插设处设置有一拉杆槽111；用于容设拉杆把手211。该拉杆槽111底部开设第一拉杆孔1111，两条竖杆212穿过顶盖11和支撑板31直至与底盖13抵接。
在一些实施例中，移动组件20还包括贴合设置于拉杆槽111外部的拉杆固定架215。拉杆固定架215正对于第一拉杆孔1111的位置设有卡设部2152；该卡设部2152外形与第一拉杆孔1111适配，并嵌套于第一拉杆孔1111中。两条竖杆212穿过拉杆固定架215和支撑板31直至与底盖13抵接。
拉杆固定架215贴合于拉杆槽111顶端的位置延展设置有平行并贴合于顶盖11的延展部2151；支撑板31设置有若干第三定位柱311，若干第三定位柱311位于延展部2151正下方，通过紧固件将拉杆固定架215锁紧于第三定位柱311上，实现了竖杆212与壳体10在 水平方向上的固定。
请参阅图2，在一些实施例中，底盖13位于伸缩拉杆21一侧的两个顶角处设置内凹的滚轮容置槽131，滚轮214容设于滚轮容置槽131内，可以有效减小包装体积，同时也起到保护滚轮214的作用。横杆213垂直固插于竖杆212端部，并贯穿滚轮容置槽131，滚轮214转动连接于横杆213的端部，实现了竖杆212与壳体10在竖直方向上的固定，避免用力过度将竖杆212从壳体10内部拔出。可以理解的是，作为配合地，中框12在于滚轮容置槽131配合的位置开设有切口，从而实现中框12与底盖13的密封固接。
在一些实施例中，移动组件20还包括固接于底盖13底部的固定件22，在静止使用移动电源的时候，该固定件22直接抵接于移动面，防止滚轮214滚动。可以理解的是，该固定件22可以是任意有效支撑于移动面、并能与移动面发生有效地摩擦力的结构。进一步地，固定件22底部设置一层防滑垫，用于增加该固定件22与移动面之间的摩擦力。
对比于现有技术，本方案提供的一种户外移动电源，采用直吹式的散热设计，无遮挡，无绕流，结构简单，散热效果好；搭配制冷片对高热量部位进行高效散热，能有效防止由于局部热量过高所导致的产品失效。
以上所述实施例仅表达了本方案的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对方案专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本方案构思的前提下，还可以做出若干变形和改进，则本方案也意图包含这些改动和变形。
