Abstract
(EN) The invention belongs to the technical field of batteries and particularly relates to a lower plastic part for a power battery. The lower plastic part comprises a first plastic part (1) for separatinga battery cell (9) from a top cover plate (8) and a second plastic part (2) which is connected with the first plastic part (1), wherein the lower plastic part has an installation state and a pre-installation state, and when the lower plastic part is in the installation state, the second plastic part (2) moves to the same-direction position of the first plastic part (1). According to the invention, the assembly steps can be simplified, the manufacturing cost can be reduced, the overall size error can be reduced, and the overall assembly effect of the battery is improved. In addition, the invention also discloses a top cover assembly structure and the power battery.
(ZH) 本发明属于电池的技术领域，具体涉及一种动力电池用下塑胶件，第一塑胶件(1)，用于间隔电池电芯(9)与顶盖片(8)；以及第二塑胶件(2)，与所述第一塑胶件(1)连接；其中，所述下塑胶件具有安装状态和预安装状态，其中，当处于所述安装状态时，所述第二塑胶件(2)运动至所述第一塑胶件(1)同向位置处。本发明能够简化装配步骤，有助于降低制造成本，还能减少整体尺寸误差，提高电池整体装配效果。此外，本发明还公开了一种顶盖装配结构及动力电池。
