此外，相对于现有技术中采用基座和框架连接，再利用框架和减振机构连接的多处连接点的方式；本方案中减振结构直接与框架单元连接，并共同集成在基座的同一位置，提高了拆装的便利性和可视性。
本发明还可做进一步改进；

具体实施方式
下面将结合附图对本发明技术方案的实施例进行详细的描述。以下实施例仅用于更加清楚地说明本发明的技术方案，因此只作为示例，而不能以此来限制本发明的保护范围。
需要注意的是，除非另有说明，本说明书及权利要求书中使用的术语或词语，不得限定为通常的或词典的意义进行解释，应立足于“发明人为了以最佳方法说明其自身的发明而适当地定义术语的概念”的原则，只解释为符合本发明的技术思想的意义和概念。
实施例一
如图1和图2所示，本发明具体实施例一提供了一种电驱动力单元减振装置，电驱动力单元包括基座100、框架单元700、电机200和电池包及电气单元300，所述电机200安装在基座100上，所述电池包及电气单元300固定在框架单元700上，减振装置包括若干弹性减振块500，减振装置设置在基座100与框架单元700之间，使框架单元700通过减振装置支撑在基座100上，框架单元700与基座100通过弹性减振块500相连形成软连接，各个弹性减振块500向电机200一侧倾斜布置，使弹性减振块500的轴线相交于电池包及电气单元300各部分的重心之上。
如图1和图2所示，通过前述设置，电驱动力单元中的电机200安装在基座100上、电池包及电气单元300可安装在框架单元700上。本实施例中的电池包及电气单元300至少包括电池包、驱动器以及其他电气部件，电池包及电气单元300固定在框架单元700上后，通过减振装置的弹性减振块500与基座100构成软连接。本实施例中的减振结构直接与框架单元700连接，并共同集成在基座100的同一位置，相对于现有技术显著提高了拆装的便利性和可视性。由于弹性减振块500采用倾斜式布置，在安装设计时，根据电池包及电气单元300的重心设计倾斜角度，使各个弹性减振块500的轴线相交于电池包及电气单元300各部分的重心之上。如图1所示，电池包重心800和驱动器重心 900均位于弹性减振块500轴线相交的下方区域内；一方面可以实现弹性减振块500对整机振动产生时的稳定支撑；另一方面通过弹性减振块500的抗振效果来减轻传递至电池包及电气单元300的振动。特别是动力单元所搭载的作业机械运行，产生不同方向大幅度振动时，可将弹性减振块500的固有振动频率设计成作业机械振动频率的1/2以下，来实现振动传递率降低至1/3以下的效果，有效避免电驱动力单元上的电气元件因振动损坏。
本实施例中的弹性减振块500主要用于吸收来自作业机械运行时产生的不同方向振动，本领域技术人员在应用中需要根据实际情况选用相应的减振材料。通常弹性减振块500材料选择应参照设备运行时的相应参数进行选择：包括电驱动力单元最大承受振动加速度、整机振动频率(实测)以及整机振动加速度(实测)。以橡胶类型的材质为例，参照材料本身的参数包括橡胶衰减常数、动倍率、橡胶个数等。
在实际选型计算中，参照如下步骤进行:
1.通过公式
Figure PCTCN2022116842-appb-000001
计算振动传递率Tr，其中F为通过橡胶后传递的力、F 0为整机振动力、a为电机最大承受振动加速度、a 0为整机振动加速度。
2.确定减振系统振动传递率Tr后，通过公式
Figure PCTCN2022116842-appb-000002
计算振动频率比λ，其中h为橡胶衰减常数。
3.确定振动频率比λ后，通过公式
Figure PCTCN2022116842-appb-000003
计算所述减振系统的总弹簧常数kz，其中ξ为整机振动频率、λ为振动频率比、m为整机总质量。
4.由总弹簧常数、橡胶个数以及动倍率确定橡胶选型后，根据橡胶的压缩弹簧常数和剪切弹簧常数确定橡胶倾斜角度。
完成设计后，反推验算，可实现目标。本实施例附图中，基座100对应电机200每侧布置的弹性减振块500数量为两个。
实施例二
如图3和图4所示，本实施例对基座100和框架单元700等结构做进一步优化；其中基座100上端设有安装电机200的第一安装部110，电机200固定于第一安装部110。第一安装部110两侧设有第二安装部120，所述第二安装部120上安装有与弹性减振块500下端连接的支撑板400。通过第一安装部110和第二安装部120，可实现基座100与电机200和电池包及电气单元300的安装稳固。各单元共同集成在基座100上，不仅提高了拆装的便利性和可视性，并且方便将整机安装在不同作业器械上。
如图3和图4所示，本实施例中提供的支撑板400包括下支撑部410和减振下安装部420。下支撑部410与第二安装部120可拆卸固定连接，减振下安装部420与弹性减振块500下端相连，所述减振下安装部420与下支撑部410之间具有夹角。这样，支撑板400可通过下支撑部410稳定安装在基座100的第二安装部120位置，同时通过减振下安装部420与弹性减振块500的下端连接；在实际应用中，由于弹性减振块500需要根据电池包及电气单元300重心调整其倾斜角度，减振下安装部420与下支撑部410之间形成的夹角以实际设计为准；在某些实施例中，为了提高设备紧凑程度、提高电驱动力单元替代燃油机的适用范围，基座100两侧的支撑板400高度根据需要调整。在本实施例中，基座100两侧的支撑板400一高一低设计，以确保设备整体紧凑性和安装的可替代性。
如图3和图4所示，本实施例中还在框架单元700两端设有连接板600，所述连接板600包括上连接部610和减振上安装部620，所述上连接部610与框架单元700固定，所述减振上安装部620与弹性减振块500上端可拆卸连接，所述减振上安装部620与上连接部610之间具有夹角；这样，连接板600的上连接部610用于与框架单元700端部固定连接，同时通过减振上安装部620与弹性减振块500的上端相连，提高减振机构与电池包及电气单元300安装的稳定性。本实施例中连接板600的上连接部610与框架单元700优先采用焊接 固定的方式安装。在实际应用中，支撑板400和连接板600采用一体冲压成型，支撑板400和连接板600材料根据需要选用，这里不再赘述。
实施例三
如图5所示，在实际安装应用中，各个弹性减振块500位于支撑板400与连接板600之间并沿支撑板400长向间隔布置。本实施例对弹性减振块500的结构进行进一步优化，具体是弹性减振块500两端设有呈锥形布置的接触部510，所述接触部510外径大于弹性减振块500外径。通过设置接触部510，可增加弹性减振块500在安装时与连接板600和支撑板400的接触面积，增加了安装的稳定性，还可降低设备运行时产生的噪音。
如图5所示，为了确保弹性减振块500与连接板600和支撑板400连接的稳定性，本实施例中弹性减振块500两端的接触部510端面设有能够与减振下安装部420和减振上安装部620可拆卸相连的插接部520。弹性减振块500能够通过插接部520与连接板600和支撑板400插接配合实现稳定安装。为了避免安装后产生晃动，本实施例在接触部510端面边缘还设有限位部530，所述限位部530能够卡入减振下安装部420和减振上安装部620。这样，限位部530能够起到限位作用，进一步确保减振机构的稳定性。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围，其均应涵盖在本发明的权利要求和说明书的范围当中。
