  • the distance between the two guide slopes 221 oppositely arranged on the same stopper 200 is recorded as the second distance D, and the first distance d is smaller than the second distance D.

  • the surface of the first tightening band 300 away from the side surface 212 in the thickness direction cannot be flush with the protruding surface 231, and then the surface of the first tightening band 300 away from the side surface 212 in the thickness direction is located in the first groove 222 and is separated from the protruding surface 231 by a certain distance.

Therefore, when the bundle is carried through the countersunk hole 2111, the second tightening band 400 cannot slide relative to the limiting member 200 in the height direction of the battery module 100, thereby preventing the second tightening band 400 from rubbing against the limiting member 200 to generate metal debris, and also preventing the metal debris from accumulating in the box of the battery pack 10 and generating electrical conduction with the battery module 100 to cause safety risks.

在其中一个实施例中，所述主体部具有沿垂直于所述电芯厚度方向延伸的端面，所述端面和所述侧面两者在所述电池模组高度方向上的尺寸相等，所述端面的面积大于所述侧面的面积。
一种用电系统，包括上述中任一项所述的电池包。
本申请的一个实施例的一个技术效果是：鉴于第一凹槽沿电芯的厚度方向延伸，在电芯厚度方向即为电池模组长度方向的情况下，当第一扎紧带与第一凹槽配合时，即便在电池模组长度变小而导致限位件远离第一扎带移动的情况下，电池模组的宽度尺寸将保持不变，使得第一扎紧带无法脱离第一凹槽而从限位件上滑落，第一扎紧带将始终与第一凹槽配合，确保第一扎紧带能够继续发挥捆绑功能，避免第一扎紧带因脱离限位件而对电池包的正常工作构成影响，从而提高电池包工作的可靠性。

参阅图1、图2和图3，本申请一实施例中提供的一种电池包10包括电池模组100、限位件200和第一扎紧带300。限位件200与电池模组100长度方向上的端部相抵接，第一扎紧带300环绕电池模组100设置并套设在限位件200上。如图1所示，电池模组100的长度方向为X轴方向，电池模组100的宽度方向为Y轴方向，电池模组100的高度方向为Z轴方向。
参阅图1、图2和图3，在一些实施例中，电池模组100包括多个电芯110，多个电芯110沿电芯110的厚度方向排列，电芯110的厚度方向也即电池模组100的长度方向。电芯110具有上盖111，上盖111用于穿设电芯110的电极，在电芯110的排列过程中，全部电芯110的上盖111均位于电池模组100高度方向上的同侧。限位件200的数量可以为两个，两个限位件200分别位于电池模组100长度方向上的两侧，使得两个限位件200分别与电池模组100长度方向上的两端相抵接，继而使得整个电池模组100被夹置在两个限位件200之间。第一扎紧带300为闭环结构，鉴于第一扎紧带300环绕电池模组100设置并套设在限位件200上，使得第一扎紧带300对两个限位件200施加扎紧力，两个限位件 200将对电池模组100施加夹紧力。在套设的过程中，第一扎紧带300沿电芯110的高度方向套设在限位件200上。故通过第一扎紧带300的作用，可以对电池模组100和限位件200起到捆绑作用，从而使得第一扎紧带300、电池模组100和限位件200三者形成一个捆绑整体。电池包10还可以包括箱体，该捆绑整体可以放置在箱体中，从而实现整个电池包10的装配。对于上述捆绑整体，通常需要使得电池模组100内的电芯110之间存在的一定的间隙，以便为电芯110循环过程中的膨胀提供一定的避位空间，避免在电芯110循环中，限位件对电芯110产生较大的束缚力，影响电池的循环性能。
参阅图1、图3和图4，在一些实施例中，限位件200可以包括主体部210、第一凸筋220和基础凸筋230。主体部210可以大致为长方体的板状结构，主体部210具有端面211、侧面212和抵接面213。端面211和抵接面213两者可以沿电池模组100的宽度方向延伸，端面211和抵接面213两者沿电池模组100的长度方向间隔设置，侧面212可以沿电池模组100的长度方向延伸，侧面212连接在端面211和抵接面213之间，端面211和抵接面213两者均可以与侧面212呈夹角设置，例如可以呈90°夹角设置。抵接面213直接与电池模组100长度方向上的端部抵接，第一扎紧带300套设在端面211和侧面212上。当抵接面213与电池模组100抵接时，侧面212可以与电池模组100宽度方向上的表面相互平齐。端面211、侧面212和抵接面213三者沿电池模组100高度方向上的尺寸可以相同，端面211和抵接面213两者的面积可以远远大于侧面212的面积。
参阅图1、图3和图4，在一些实施例中，第一凸筋220和基础凸筋230可以沿电池模组100的高度方向延伸，使得第一凸筋220和基础凸筋230可以位于同一直线上。第一凸筋220和基础凸筋230两者均凸出设置在侧面212上，使得第一凸筋220和基础凸筋230两者均相对侧面212凸出一定的高度。第一凸筋220相对基础凸筋230更靠近电芯110的上盖111，可以通俗理解为第一凸筋220位于基础凸筋230的上方。第一凸筋220和基础凸筋230两者间隔设置，基础凸筋230和第一凸筋220之间的间隔空隙将形成第一凹槽222，可以理解为基础凸筋230、第一凸筋220和侧面212三者共同围成第一凹槽222。显然，第一凹槽222沿电池模组100的长度方向延伸一定的长度。当第一扎紧带300套设在主体部210上时，第一扎紧带300将与第一凹槽222配合，第一凹槽222将对第一扎紧带300起到很好的限位作用，提高第一扎紧带300的安装精度。
假如采用在主体部210的端面211上开设有凹槽的模式，该凹槽沿电池模组100的宽度方向延伸，扎紧带与凹槽配合。由于被捆绑后的池模组内的电芯110之间存在的一定的间隙，在电芯110相互靠近而导致间隙缩小的情况下，电池模组100的长度将变小，也使得两个限位件200能够相互靠近而减少间距。故当两个限位件200相互靠近时，由于扎紧带的长度保持恒定，将使得扎紧带脱离凹槽而从限位件200上滑落，继而影响电池包10的正常工作，由此将影响电池包10工作的可靠性。并且，端面211上的凹槽的延伸长度较大，会增大凹槽的加工成本，从而提高电池包10的制造成本。
而对于上述实施例中的电池包10，鉴于第一凹槽222沿电池模组100的长度方向延伸，第一扎紧带300与第一凹槽222配合，即便在电池模组100长度变小而导致两个限位件200相互靠近的情况下，电池模组100的宽度尺寸将保持不变，使得第一扎紧带300无法脱离第一凹槽222而从限位件200上滑落，第一扎紧带300将始终与第一凹槽222配合，确保第一扎紧带300能够继续发挥捆绑功能，避免第一扎紧带300因脱离限位件200而对 电池包10的正常工作构成影响，从而提高电池包10工作的可靠性。并且，鉴于侧面212的面积小于端面211的面积，使得第一凹槽222的宽度相对较小，从而减少第一凹槽222的加工成本，最终降低整个电池包10的制造成本。可以理解，鉴于电芯110内部的特殊结构，在电芯110循环的过程中，电芯110的宽度尺寸可以保持不变，使得整个电池模组100的宽度尺寸保持不变。
参阅图1、图3和图4，在一些实施例中，第一凸筋220远离基础凸筋230的一端延伸至侧面212靠近上盖111的一端，可以通俗理解为第一凸筋220的上端与侧面212的上端相互平齐。第一凸筋220具有导向斜面221。从导向斜面221远离基础凸筋230的一端至靠近基础凸筋230的一端，也可以通俗理解为从导向斜面221的上端至下端，或者沿第一扎紧带300的安装方向，导向斜面221到侧面212的距离逐渐增大。在第一扎紧带300的安装过程中，可以首先使得第一扎紧带300套设在导向斜面221上，然后对第一扎紧带300套施加向下的压力，使得第一扎紧带300沿着导向斜面221向下滑动至第一凹槽222内，以便第一扎紧带300与第一凹槽222配合，从而实现第一扎紧带300的安装。导向斜面221与侧面212之间夹角α的取值范围为2°至10°，例如导向斜面221与侧面212之间夹角可以为2°、5°或10°等。导向斜面221靠近基础凸筋230的一端到侧面212的距离A为0.5mm至1mm，也即导向斜面221的下端到侧面212的距离为0.5毫米至1毫米，也可以理解为导向斜面221到侧面212的最大距离为0.5mm至1mm。例如导向斜面221的下端到侧面212的距离可以为0.5mm、0.5mm或1mm等。鉴于导向斜面221的上述设置，可以使得导向斜面221具有良好的导向功能，便于第一扎紧带300顺利与第一凹槽222配合，从而提高第一凹槽222的安装效率。
参阅图4和图5，第一扎紧带300沿电池模组100长度方向延伸的两段之间的间距记为第一间距d，第一间距d可以理解为电池模组100长度方向延伸的两段的内表面之间的距离，同一限位件200上相对设置的两个导向斜面221之间的间距记为第二间距D，第一间距d小于第二间距D。因此，在使得第一扎紧带300沿导向斜面221下滑的过程中，第一扎紧带300将对导向斜面221产生压力，当第一扎紧带300与第一凹槽222配合时，可以使得第一凸筋220对第一扎紧带300施加阻挡力，防止第一扎紧带300越过第一凸筋220而脱离第一凹槽222配。
参阅图1、图3和图4，在一些实施例中，基础凸筋230具有凸出面231，凸出面231到侧面212的距离B保持恒定，使得基础凸筋230大致呈长方体状，凸出面231到侧面212的距离B的取值范围为1mm至3mm，例如凸出面231到侧面212的距离B可以为1mm、2mm或3mm等。凸出面231到侧面212的距离可以理解为基础凸筋230相对侧面212的凸出高度。凸出面231到侧面212的距离大于第一扎紧带300的厚度，且凸出面231到侧面212的距离与第一扎紧带300的厚度之差大于第一扎紧带300厚度的一半。当第一扎紧带300与第一凹槽222配合时，使得第一扎紧带300厚度方向上远离侧面212的表面无法与凸出面231平齐，继而使得第一扎紧带300厚度方向上远离侧面212的表面位于第一凹槽222内并与凸出面231间隔一定距离，如此将加大第一扎紧带300越过凸出面231而脱离第一凹槽222的难度，进一步提高电池包10工作的可靠性。
参阅图1、图2和图5，在一些实施例中，第一扎紧带300包括带主体310和绝缘套320，带主体310采用钢材料制成，绝缘套320采用柔性材料制成并具有绝缘性能。带主 体310包括相互连接的第一段311和第二段312，第一段311套设在主体部210上，带主体310除却第一段311后的剩余部分将形成第二段312，第二段312位于主体部210之外并与电池模组100对应，绝缘套320套设在第二段312上。鉴于绝缘套320套设在第二段312，可以有效防止第二段312与电池模组100内的电芯110接触而产生短路。
在一些实施例中，第一段311还包括嵌设部3111，嵌设部3111与第一凹槽222配合，绝缘套320套设在至少部分嵌设部3111上。通过将绝缘套320套设在至少部分嵌设部3111上，绝缘套320为柔性材料，易于压缩，更易于将第一扎紧带300沿着导向斜面221向下滑动至第一凹槽222内，在第一扎紧带300沿导向斜面221向下滑动而与第一凹槽222配合的过程中，使得绝缘套320与导向斜面221直接接触，可以有效防止硬度较大的嵌设部3111与导向斜面221产生较大摩擦，避免摩擦产生的金属碎屑集聚在电池包10的箱体内并与电池模组100产生电性导通作用而造成安全风险。
在一些实施例中，主体部210的端面211上开设有沉孔2111，沉孔2111的数量可以为多个，对于第一扎紧带300、电池模组100和限位件200三者形成的捆绑整体，可以通过沉孔2111对捆绑整体施加作用力，以便对捆绑整体进行搬运。第一扎紧带300的宽度可以大于或等于第一凹槽222的宽度，使得第一扎紧带300抵紧在第一凸筋220和基础凸筋230之间，也理解为第一扎紧带300与第一凹槽222形成过盈配合关系。故在对捆绑整体通过沉孔2111进行搬运的过程，可以使得第一扎紧带300无法在电池模组100的高度方向上相对限位件200产生滑动，避免第一扎紧带300与限位件200摩擦而产生金属碎屑，同样避免金属碎屑集聚在电池包10的箱体内并与电池模组100产生电性导通作用而造成安全风险。
参阅图1、图2和图3，在一些实施例中，电池包10还包括第二扎紧带400，限位件200还包括第二凸筋240，第二凸筋240凸出设置在侧面212上，第二凸筋240可以沿电池模组100的高度方向延伸，使得第一凸筋220、第二凸筋240和基础凸筋230三者均位于同一直线上。基础凸筋230位于第一凸筋220和第二凸筋240之间，第二凸筋240和基础凸筋230沿电池模组100的高度方向间隔设置，第二凸筋240和基础凸筋230之间的间隔空间形成第二凹槽242，即第二凸筋240、基础凸筋230和侧面212三种共同围成第二凹槽242，第二凹槽242同样沿电池模组100的长度方向延伸，即第一凹槽222和第二凹槽242相互平行设置。第二扎紧带400与第一扎紧带300的作用相同，第二扎紧带400同样环绕电池模组100设置并套设在主体部210上，使得电池模组100被夹置在两个限位件200之间，故第二扎紧带400可以起到加强捆绑的作用。通过第二扎紧带400与第二凹槽242配合，在电池模组100的长度产生变化而使得两个限位件200相互靠近时，同样使得第二扎紧带400无法脱离第二凹槽242。
在一些实施例中，第二扎紧带400可以采用塑胶材料制成，例如可以使得第二扎紧带400具有一定的弹性。第二凸筋240相对侧面212的凸出高度恒定，且第二凸筋240相和基础凸筋230相对侧面212的凸出相等。鉴于第二扎紧带400的材质相对第一扎紧带300的材质较软，可以使得第二凸筋240无需如第一凸筋220设置导向斜面221，如此可以合理降低限位件200的加工成本，从而降低电池包10的制造成本。
在一些实施例中，第二扎紧带400的宽度可以大于或等于第二凹槽242两者的宽度，使得第二扎紧带400抵紧在第二凸筋240和基础凸筋230之间，可以理解为第二扎紧带 400与第二凹槽242形成过盈配合关系。故在对捆绑整体通过沉孔2111进行搬运的过程，可以使得第二扎紧带400无法在电池模组100的高度方向上相对限位件200产生滑动，避免第二扎紧带400与限位件200摩擦而产生金属碎屑，同样避免金属碎屑集聚在电池包10的箱体内并与电池模组100产生电性导通作用而造成安全风险。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
