具体实施方式
以下结合附图对本申请的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本申请，并不用于限制本申请。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
本申请提供一种电池托盘100，如图2和图3所示，该电池托盘100包括底板1以及围绕底板1设置的侧板2，侧板2上固定有用于安装该电池托盘100的吊耳3，其中，如图3和图4所示，侧板2上设置有承托部21，吊耳3具有支撑在承托部21底面211上的支撑部31。例如，该电池托盘100在安装时，承托部21的底面211设置为水平，以使得支撑部31能够对承托部21提供竖直向上的支撑力，更利于对电池托盘100进行支撑。
本申请提供的电池托盘100，通过在侧板2上设置承托部21，由吊耳3的支撑部31支撑在承托部21下方，可以通过支撑部31对电池托盘100起到支撑作用，而不仅仅依靠吊耳3与电池托盘100的侧板2之间的焊缝来承受吊耳的承重，这样大大提高了吊耳3的受力强度。因此，本申请提供的设计相比现有技术中将吊耳2’焊接在侧壁1’上，仅通过吊耳2’与侧壁1’两者之间的焊缝来承重的方式相比，克服了现有技术中吊耳2’在长时间的颠簸或遭遇剧烈碰撞时焊缝处发生失效断裂的问题，由此可以保证电池托盘100安装的可靠性。
在本申请的一些实施方式中，如图3和图4所示，侧板2上的承托部21可以为侧板2上向外突出设置的凸部。例如在本申请的一些具体示例中，该凸部可以为沿侧板2的周向延伸设置的凸缘，这样在侧板2上的该凸缘上，可以间隔设置多个吊耳3(如图2)。当然，本申请不限于此，也可以在仅设置吊耳3的部位设置作为承托部21的凸部。
此外，侧板2上的承托部21不仅可以为凸部的形式，例如，也可在侧板2上设置凹槽(图未示出)，凹槽的位于上方的壁形成为承托部21，吊耳的支撑部31可以伸入该凹槽中以支撑在凹槽上方的壁上。
为使得吊耳3能够被吊装，吊耳3还可以具有用于吊装该电池托盘100的吊装部32，该吊装部32上设置有吊装孔322，以方便通过该吊装孔322吊装该电池托盘100。当然吊装部32也可以设计为能够固定在车身上的其它结构形式。
另外，为增加吊耳3的强度，可以在吊装部32与支撑部31之间设置加强筋33，以避免吊装部32被吊装时因较大的承重力导致吊装部32与支撑部31之间产生断裂。例如在本申请的一些实施例中，吊耳3的具体结构可以如图6所示。
本申请的一些实施方式中，吊耳3的吊装部32可以具有第一侧面321，第一侧面321与承托部21的外侧面212贴合。例如在本申请的一些具体示例中，吊装部32的第一侧面321与承托部21的外侧面212可以通过焊接固定。支撑部31可以具有支撑面311，支撑面311支撑承托部21。例如在本申请的一些具体示例中，支撑面311与承托部21的底面211可以通过焊接固定。由此，当将吊耳3的第一侧面321和支撑面311分别与承托部21的两个面(即外侧面212和底面211)配合焊接，可以增加焊接面积，同时通过吊耳3的支撑面311与侧板2的承托部21的配合，可以对吊耳3起到承重的作用，使得吊耳3可以同时通过支撑和焊接来保证连接的可靠性。
例如图3-图5所示的实施例中，承托部21的底面211与外侧面212可以垂直，吊装部32的第一侧面321与支撑部31的支撑面311可以形成为“L”形结构。这样，当吊耳3固定在侧板2上时，吊耳3的支撑面311与承托部21的底面211贴合，吊耳3的第一侧面321与承托部21的外侧面212贴合。
在本申请的一些实施例中，吊耳3的支撑部31还可以具有第二侧面312，第二侧面312与侧板2的下部外表面213(即承托部21下方的外表面)贴合，吊耳3的第一侧面321、支撑部31的支撑面311、和支撑部31的第二侧面312可以形成Z字形结构(这里，需要说明的是，本段的“Z字形结构”旨在说明：第一侧面321和第二侧面312分别位于支撑面311的两侧且朝向相反的方向延伸)。另外，为增加吊耳3在侧板2上的牢固性，该第二侧面312也可以通过焊接的方式与侧板2的下部外表面213连接。
本领域技术人员可以理解的是，吊耳3并不限于通过焊接的方式固定在侧板2上，还可以通过螺栓连接等固定在侧板2上。但是，通过螺栓连接的方式有可能需要在侧板2上打螺栓孔，当在侧板2上打螺栓孔时，需要注意电池托盘100的密封性是否符合要求。
此外，如图5所示，本实施方式中该电池托盘100所采用的侧板2可以为空心结构，空心结构的侧板2在增加侧板2的刚度的同时可以减轻电池托盘100的重量。在本申请的一些具体示例中，该侧板2可以直接采用具有内部空腔的型材制成。
根据本申请的另一方面，还提供一种电池包1000，如图7所示，该电池包1000可以包括如上的电池托盘100、盖在电池托盘100上的盖板200以及位于电池托盘100和盖板200之间的空间内的电池组300。
该电池包1000括通过电池托盘100上的吊耳3安装在车身上，由于如上的电池托盘100的吊耳3的承重能力增强，该电池包1000通过吊耳3安装在车身上，安装牢固可靠，不会 因车辆长时间颠簸或剧烈碰撞导致吊耳3的焊缝开裂而出现电池托盘100掉落的可能。
以上结合附图详细描述了本申请的优选实施方式，但是，本申请并不限于此。在本申请的技术构思范围内，可以对本申请的技术方案进行多种简单变型，包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本申请对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本申请所公开的内容，均属于本申请的保护范围。
