| 中文摘要: |
| 以装配式密封条为例，介绍动力电池包密封条的设计要素，包括开发体系和分类、断面设计、性能要求、材料选择、定位精度和尺寸公差。密封条的上、下表面接触压力大于0.01 MPa，密封条即实现安全密封，密封等级达到IPX7。密封条橡胶材料的主体材料选用三元乙丙橡胶最佳，密封条的尺寸公差采用M1等级，定位采用分区定位法。 |
| 英文摘要: |
| Taking the assembled sealing strip as example，the design dominants for the sealing strip of the power battery package include development system and classification，sections design，performance requirement，material selection，positioning accuracy and dimension tolerance.The contacting forces between the upper and lower surfaces of the sealing strip were greater than 0.01 MPa，sealing strip achieved safety sealing，and the sealing level reached IPX7.The optimal selection for main material of the sealing strip rubber material was ethylene-propylene-diene rubber（EPDM），and the dimension tolerance of the sealing strip adopted M1 level，the partition adopted positioning method. |
