车体连接组件及车辆 技术领域
本申请涉及车辆结构技术领域，特别是涉及一种车体连接组件及车辆。
背景技术
由于锂离子等电池具有能量密度高、功率密度高、循环使用次数多、存储时间长等优点，因此在电动车中得到了广泛的应用。
但是，目前电池在电动车中安装时占用空间较大。
发明内容
本申请的目的在于减小电池在电动车中安装所占用的空间。
根据本申请的第一方面，提供了一种车体连接组件，包括：
地板，设置有通槽；
门槛梁，沿第一方向位于地板的一侧，门槛梁用于连接车体；
安装侧梁，连接于门槛梁靠近地板的一侧；和
电池，至少部分位于地板下方，且沿第一方向安装于安装侧梁远离门槛梁的一侧，电池包括箱体组件，箱体组件包括上箱体，上箱体封闭通槽。
该实施例的车体连接组件通过电池的上箱体的顶壁封闭地板上的通槽，将上箱体的顶壁作为地板的一部分，能够在保证地板完整性的基础上，节省安装电池时在高度方向上占用的空间，以便安装厚度更大的电池，从而提高电池的能量密度以延长车辆的续航时间，或者为在车辆中安装其它部件留出空间，降低了车辆内布局的难度，还可使车体连接组件更加轻量化。
在一些实施例中，门槛梁和安装侧梁均沿第二方向延伸，第二方向垂直于第一方向。
该实施例使门槛梁沿第二方向延伸，能够提高地板沿车辆长度方向的结构稳定性，从而使车辆结构更加稳定；而且，安装侧梁也沿第二方向延伸，能够在第一方向上为电池留出更多的空间。
在一些实施例中，门槛梁靠近地板的部分与安装侧梁之间密封。
该实施例考虑到此种电池安装方式会使电池与通槽之间存在第一间隙，门槛梁靠近地板的部分与安装侧梁之间具有第二间隙，车内的杂质、异物或水汽容易通过第一间 隙和第二间隙进入到安装侧梁远离电池的一侧，通过将门槛梁靠近地板的部分与安装侧梁之间密封，可消除第二间隙，以防止车内的杂质或异物进入到门槛梁与安装侧梁之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命。而且，也可防止门槛梁与安装侧梁之间的杂质或水汽通过第二间隙进入到电池的安装区域，以提高电池工作的可靠性和安全性。
在一些实施例中，门槛梁包括第一主体部和搭接部，搭接部沿第一方向连接于第一主体部靠近电池的一侧；
安装侧梁包括第二主体部和延伸部，延伸部沿第一方向连接于第一主体部远离电池的一侧；

该实施例将门槛梁与安装侧梁连接在一起，可提高整体结构刚度，使电池的安装更加牢固，可防止安装侧梁发生变形使电池发生位置改变或倾斜，有利于保证地板的整体性。而且，门槛梁与安装侧梁的此种连接结构可减小其在第一方向上占用的空间，以增加电池的安装空间；另外，通过搭接部覆盖第二主体部，可在搭接部与第二主体部之间形成支撑，进一步提高整体结构刚度，防止门槛梁与安装侧梁发生变形，还能提高车内位于地板上方的区域与门槛梁和安装侧梁之间区域隔开，防止车内的异物、杂质或水汽进入车体连接组件内。
在一些实施例中，车体连接组件还包括密封件，密封件设在搭接部与第二主体部之间，用于实现搭接部与第二主体部之间的密封。
该实施例通过在搭接部与第二主体部之间设置密封件，能够提高门槛梁与安装侧梁之间连接的密封性，防止车内的杂质或异物进入到门槛梁与安装侧梁之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命。而且，也可防止门槛梁与安装侧梁之间的杂质或水汽通过第二间隙进入到电池的安装区域，以提高电池工作的可靠性和安全性。而且，通过密封件实现密封易于装配，并保证密封效果，且对于不同车体连接组件可保证装配的一致性。

搭接部和第二主体部相对的面上分别设有第一凹入部和第二凹入部，第一凸起部嵌入第一凹入部，第二凸起部嵌入第二凹入部。
该实施例中密封件沿第三方向的两侧分别与门槛梁和安装侧梁之间形成凹凸配合，可延长搭接部与第二主体部之间的密封路径，优化密封效果。而且，此种配合结构能够起到连接搭接部与第二主体部的作用，在车体连接组件受到振动或冲击作用时，密封件与搭接部与第二主体部之间的凹凸配合结构能够限制门槛梁和安装侧梁之间沿第一方向相互错动，提高整体刚度，且密封件也能起到吸收振动的作用。
在一些实施例中，密封件包括多个第一凸起部和多个第二凸起部，多个第一凸起部和多个第二凸起部沿第一方向错开设置。
该实施例通过对密封件设置多个第一凸起部和多个第二凸起部，并将其沿第一方向错开设置，以使密封件在整个密封长度上的密封性更加均匀，并使密封件与搭接部和第二主体部之间的连接更牢固，提高门槛梁和安装侧梁之间密封连接的可靠性。
在一些实施例中，密封件的延伸方向与门槛梁和安装侧梁一致，且延伸长度覆盖搭接部与第二主体部的整个配合长度。
该实施例使密封件沿第二方向的延伸长度与和搭接部与第二主体部的配合长度一致，能够提高门槛梁和安装侧梁在整个配合长度上的密封性能，从而保证整体的密封效果。
在一些实施例中，搭接部相对于第二主体部沿第一方向缩回预设距离，且缩回区域涂覆密封剂。
该实施例通过在搭接部相对于第二主体部缩回的区域涂覆密封剂，可进一步保证门槛梁和安装侧梁在靠近电池位置连接的气密性和水密性，既能可靠地防止车内的杂质或异物进入到门槛梁与安装侧梁之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命，也能对门槛梁和安装侧梁在靠近端部的位置连接，从而提高整体连接刚度。
在一些实施例中，门槛梁包括第一主体部和搭接部，搭接部沿第一方向连接于第一主体部靠近电池的一侧，安装侧梁包括第二主体部和延伸部，延伸部沿第一方向连接于第二主体部远离电池的一侧，第一主体部与延伸部可拆卸连接。
该实施例在搭接部与第二主体部相互搭接的基础上，将第一主体部与延伸部也可拆卸连接，能够提高门槛梁与安装侧梁之间的连接刚度，利于增加整体弯曲刚度和弯曲模态，使车体连接结构具有更好的抗振动和冲击效果。而且，第一主体部与延伸部可拆卸连接，可方便地实现门槛梁和安装侧梁中单个部件的更换和维修，且易于装配。
在一些实施例中，车体连接组件还包括螺母板和多个紧固件，第一主体部靠近延伸部的位置设有空腔，螺母板设在空腔内，门槛梁和安装侧梁均沿第二方向延伸，第二方向垂直于第一方向，延伸部和第一主体部均沿第二方向间隔设置多个安装孔，螺母板 包括沿第二方向间隔设置的多个螺母接口，紧固件依次穿过延伸部和第一主体部各自的安装孔与相应的螺母接口连接。

在一些实施例中，第一主体部与延伸部之间设有凹凸配合结构，并在凹凸配合结构处连接。
该实施例通过在第一主体部与延伸部之间设置凹凸配合结构，使第一主体部与延伸部之间交错设置，可增强门槛梁与安装侧梁连接后的整体弯曲刚度和弯曲模态。
在一些实施例中，第一主体部与延伸部之间在连接处之间设置有粘接层。
该实施例通过在第一主体部与延伸部之间的连接处设置粘接层，能够在安装紧固件时防止门槛梁与安装侧梁之间发生位置错动，并提高提高第一主体部与延伸部连接的可靠性，还可提高连接的密封性。

本申请的实施例所提到的电池是指包括多个电池单体以提供更高的电压和容量的单一的物理模块。例如，本申请中所提到的电池可以包括电池模块或电池包等。
电池单体可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：柱形电池单体、方形电池单体和软包电池单体，本申请实施例对此也不限定。
发明人通过研究发现，传统的电池在车辆中安装时，一般是将门槛梁与地板焊接，并将车体连接于门槛梁顶部，地板采用整体结构，电池整体设在地板下方，且安装于位于门槛梁一侧的安装梁上，因此，电池安装时在竖直方向占用的尺寸较大。而且安装梁与门槛梁在靠近地板的部分相互独立，电池的安装可靠性取决于安装梁自身的强度，对安装梁的强度要求较高。
对于此种安装方式，电池箱体的顶壁、箱体与地板之间的间隔距离以及地板的厚度均会占用竖直方向的尺寸，使电池安装时需要在竖直方向占用较大的尺寸。为了减小在竖直方向占用空间，以便安装厚度更大的电池或者为安装其它部件留出空间，发明人突破传统的思维，想到将电池的箱体的顶壁作为地板的一部分，这样在电池所在位置同时省去了地板厚度以及箱体与地板之间的间隔距离。
按照此种思路，本申请欲对车体连接组件进行改进。车体连接组件包括：地板、门槛梁、安装侧梁和电池。其中，地板设置有通槽，门槛梁沿第一方向位于地板的一侧，门槛梁用于连接车体；安装侧梁连接于门槛梁靠近地板的一侧；电池的至少部分位于地板下方，且沿第一方向安装于安装侧梁远离门槛梁的一侧，电池包括箱体，箱体包括上箱体，上箱体封闭通槽。
此种车体连接组件通过电池的上箱体的顶壁封闭地板上的通槽，能够节省安装电池时在高度方向上占用的空间，以便安装厚度更大的电池，从而提高电池的能量密度以延长车辆的续航时间，或者为在车辆中安装其它部件留出空间，降低了车辆内布局的难度。
如图1所示，用电装置可以是车辆200，例如新能源汽车，新能源汽车可以是纯电动汽车、混合动力汽车或增程式汽车等；或者用电装置也可以是无人机或轮船等。具体地，车辆200可包括车桥201、连接于车桥201的车轮202、马达203、控制器204和电 池100，马达203用于驱动车桥201转动，控制器204用于控制马达203工作，电池100可以设置在车辆200的底部、头部或尾部，用于为马达203以及车辆中其它部件的工作提供电能。
进一步地，车辆200还可包括车体和上述实施例的车体连接组件，车体连接于门槛梁的顶部。
图2为本申请电池100的一些实施例的结构示意图，电池100包括箱体组件101和电池单体10。在电池100中，电池单体10可以是一个，也可以是多个。若电池单体10为多个，多个电池单体10之间可串联或并联或混联，混联是指多个电池单体10中既有串联又有并联，可以是多个电池单体10先串联或并联或混联组成电池模块，多个电池模块再串联或并联或混联形成一个整体，并容纳于箱体组件101内。也可以是所有电池单体10之间直接串联或并联或混联在一起，再将所有电池单体10构成的整体容纳于箱体组件101内。
箱体组件101内部为中空结构，至少一个电池模块100’容纳于箱体组件101内。例如，箱体组件101可以包括上箱体101A和下箱体101B。上箱体101A和下箱体101B扣合在一起。例如，上箱体101A和下箱体101B均可以为中空长方体且各自只有一个面为开口面，上箱体101A的开口和下箱体101B的开口相对设置，并且上箱体101A和下箱体101B相互扣合形成具有封闭腔室的箱体。也可以为，上箱体101A为具有开口的长方体而下箱体101B为板状，或者下箱体101B为具有开口的长方体而上箱体101A为板状，上箱体101A和下箱体101B相对设置并扣合而形成具有封闭腔室的箱体。至少一个电池模块100’相互并联或串联或混联组合后，置于上箱体101A和下箱体101B扣合后形成的封闭腔室内。
在一些实施例中，如图3所示，本申请提供了一种车体连接组件，包括：地板1、门槛梁2、安装侧梁3和电池100。
地板1上设置有通槽11；门槛梁2沿第一方向x位于地板1的一侧，门槛梁2用于连接车体；安装侧梁3连接于门槛梁2靠近地板1的一侧；电池100的至少部分位于地板1下方，且沿第一方向x安装于安装侧梁3远离门槛梁2的一侧，电池100包括箱体组件101，箱体组件101包括上箱体101A，上箱体101A封闭通槽11。第一方向x可以为车辆的宽度方向。
其中，通槽11的形状可与电池100的形状相适配，通槽11的尺寸也可与电池100的外周尺寸适配，既能使电池100位于通槽11内，以便通过电池100的上箱体101A封闭通槽11，也能减小电池100与通槽11之间的间隙，防止异物从车体内通过该间隙落入电 池100的安装空间内。电池100的大部分位于地板1下方，电池100的顶部可伸入通槽11内以封闭通槽11，电池100的顶面可与地板1的上表面平齐、低于地板1的上表面或高于地板1的上表面。
门槛梁2整体为长条状结构，是车身中的重要组成部分，安装在地板1的侧部，例如可沿车辆的前后方向延伸，门槛梁2的顶部可连接车体。安装侧梁3连接于门槛梁2靠近地板1的一侧，用于安装电池100，且电池100沿第一方向x安装于安装侧梁3远离门槛梁2的一侧，使安装侧梁3的至少部分位于电池100与门槛梁2之间。其中，门槛梁2和安装侧梁3均可采用框架形式结构，既能满足结构强度，又能实现车体连接组件的轻量化。
该实施例的车体连接组件通过电池100的上箱体101A的顶壁封闭地板1上的通槽11，将上箱体101A的顶壁作为地板1的一部分，能够在保证地板1完整性的基础上，节省安装电池时在高度方向上占用的空间，以便安装厚度更大的电池100，从而提高电池100的能量密度以延长车辆的续航时间，或者为在车辆中安装其它部件留出空间，降低了车辆内布局的难度，还可使车体连接组件更加轻量化。
在一些实施例中，如图4所示，门槛梁2和安装侧梁3均沿第二方向y延伸，第二方向y垂直于第一方向x，第二方向y可以为车辆的长度方向。
该实施例使门槛梁2沿第二方向y延伸，能够提高地板1沿车辆长度方向的结构稳定性，从而使车辆结构更加稳定；而且，安装侧梁3也沿第二方向y延伸，能够在第一方向x上为电池100留出更多的空间。
在一些实施例中，门槛梁2靠近地板1的部分与安装侧梁3之间密封。
密封形式可采用多种，例如，涂覆密封胶或设置密封件等。门槛梁2靠近地板1的部分与安装侧梁3之间可仅进行密封，或者也可在密封的基础上连接，以进一步提高密封的可靠性。
该实施例考虑到此种电池安装方式会使电池100与通槽11之间存在第一间隙，门槛梁2靠近地板1的部分与安装侧梁3之间具有第二间隙，车内的杂质、异物或水汽容易通过第一间隙和第二间隙进入到安装侧梁3远离电池100的一侧，通过将门槛梁2靠近地板1的部分与安装侧梁3之间密封，可消除第二间隙，以防止车内的杂质或异物进入到门槛梁2与安装侧梁3之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命。而且，也可防止门槛梁2与安装侧梁3之间的杂质或水汽通过第二间隙进入到电池100的安装区域，以提高电池100工作的可靠性和安全性。
在一些实施例中，如图5所示，门槛梁2包括第一主体部21和搭接部22，搭接部 22沿第一方向x连接于第一主体部21靠近电池100的一侧。如图6所示，安装侧梁3包括第二主体部31和延伸部32，延伸部32沿第一方向x连接于第一主体部21远离电池100的一侧。其中，第一主体部21与延伸部32连接，搭接部22位于第二主体部31上方，且搭接部22与第二主体部31之间密封。
例如，门槛梁2与安装侧梁3均可设计为框架结构，其内部设有多个横向和/或纵向的隔板，不仅能增加框架结构的强度，还能起到减重作用。例如，在垂直于第二方向y的横截面内，第一主体部21可呈类似矩形的结构，搭接部22可沿第一方向x连接于第一主体部21靠近电池100的一侧，搭接部22可采用板状结构，或板状结构与框架结构结合的形式，在第一方向x上，搭接部22可延伸至与安装侧梁3靠近电池100的一侧平齐，或者缩回预设距离。第二主体部31可呈矩形，其高度可与电池100的高度一致，延伸部32连接于第二主体部31沿第一方向x远离电池100的一侧，且位于第二主体部31的底部区域。
该实施例将门槛梁2与安装侧梁3连接在一起，可提高整体结构刚度，使电池100的安装更加牢固，可防止安装侧梁3发生变形使电池100发生位置改变或倾斜，有利于保证地板1的整体性。而且，门槛梁2与安装侧梁3的此种连接结构可减小其在第一方向x上占用的空间，以增加电池100的安装空间；另外，通过搭接部22覆盖第二主体部31，可在搭接部22与第二主体部31之间形成支撑，进一步提高整体结构刚度，防止门槛梁2与安装侧梁3发生变形，还能提高车内位于地板1上方的区域与门槛梁2和安装侧梁3之间区域隔开，防止车内的异物、杂质或水汽进入车体连接组件内。
在一些实施例中，车体连接组件还包括密封件4，密封件4设在搭接部22与第二主体部31之间，即密封件4设在搭接部22与第二主体部31之间的第二间隙内，用于实现搭接部22与第二主体部31之间的密封。例如，密封件4可采用橡胶件等具有弹性的零件，以在安装状态下通过压缩实现密封。
该实施例通过在搭接部22与第二主体部31之间设置密封件4，能够提高门槛梁2与安装侧梁3之间连接的密封性，防止车内的杂质或异物进入到门槛梁2与安装侧梁3之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命。而且，也可防止门槛梁2与安装侧梁3之间的杂质或水汽通过第二间隙进入到电池100的安装区域，以提高电池100工作的可靠性和安全性。而且，通过密封件4实现密封易于装配，并保证密封效果，且对于不同车体连接组件可保证装配的一致性。
在一些实施例中，如图7所示，密封件4包括密封板41、第一凸起部42和第二凸起部43，门槛梁2和安装侧梁3均沿第二方向y延伸，第二方向y垂直于第一方向x，第 一凸起部42和第二凸起部43分别设在密封板41沿第三方向z的两侧，第三方向z垂直于第一方向x和第二方向y，第三方向z可以为车辆的高度方向。如图5和图6所示，搭接部22和第二主体部31相对的面上分别设有第一凹入部221和第二凹入部311，第一凸起部42嵌入第一凹入部221，第二凸起部43嵌入第二凹入部311。
该实施例中密封件4沿第三方向z的两侧分别与门槛梁2和安装侧梁3之间形成凹凸配合，可延长搭接部22与第二主体部31之间的密封路径，优化密封效果。而且，此种配合结构能够起到连接搭接部22与第二主体部31的作用，在车体连接组件受到振动或冲击作用时，密封件4与搭接部22与第二主体部31之间的凹凸配合结构能够限制门槛梁2和安装侧梁3之间沿第一方向x相互错动，提高整体刚度，且密封件4也能起到吸收振动的作用。
在一些实施例中，如图7所示，密封件4包括多个第一凸起部42和多个第二凸起部43，多个第一凸起部42和多个第二凸起部43沿第一方向x错开设置。
例如，多个第一凸起部42和多个第二凸起部43沿第一方向x交替设置。
该实施例通过对密封件设置多个第一凸起部42和多个第二凸起部43，并将其沿第一方向x错开设置，以使密封件4在整个密封长度上的密封性更加均匀，并使密封件4与搭接部22和第二主体部31之间的连接更牢固，提高门槛梁2和安装侧梁3之间密封连接的可靠性。
在一些实施例中，密封件4的延伸方向与门槛梁2和安装侧梁3一致，且延伸长度覆盖搭接部22与第二主体部31的整个配合长度。
该实施例使密封件4沿第二方向y的延伸长度与和搭接部22与第二主体部31的配合长度一致，能够提高门槛梁2和安装侧梁3在整个配合长度上的密封性能，从而保证整体的密封效果。
在一些实施例中，如图3所示，搭接部22相对于第二主体部31沿第一方向x缩回预设距离，且缩回区域涂覆密封剂5，例如，PVC胶等。
该实施例通过在搭接部22相对于第二主体部31缩回的区域涂覆密封剂5，可进一步保证门槛梁2和安装侧梁3在靠近电池100位置连接的气密性和水密性，既能可靠地防止车内的杂质或异物进入到门槛梁2与安装侧梁3之间，避免对结构件造成损伤或腐蚀，提高车辆的使用寿命，也能对门槛梁2和安装侧梁3在靠近端部的位置连接，从而提高整体连接刚度。
在一些实施例中，门槛梁2包括第一主体部21和搭接部22，搭接部22沿第一方向x连接于第一主体部21靠近电池100的一侧，安装侧梁3包括第二主体部31和延伸部 32，延伸部32沿第一方向x连接于第二主体部31远离电池100的一侧，第一主体部21与延伸部32可拆卸连接，例如，可采用紧固件连接或卡接等形式。
该实施例在搭接部22与第二主体部31相互搭接的基础上，将第一主体部21与延伸部32也可拆卸连接，能够提高门槛梁2与安装侧梁3之间的连接刚度，利于增加整体弯曲刚度和弯曲模态，使车体连接结构具有更好的抗振动和冲击效果。而且，第一主体部21与延伸部32可拆卸连接，可方便地实现门槛梁2和安装侧梁3中单个部件的更换和维修，且易于装配。
在一些实施例中，如图3所示，车体连接组件还包括螺母板6和多个紧固件7，第一主体部21靠近延伸部32的位置设有空腔212，螺母板6设在空腔212内，螺母板6可沿第二方向y延伸。门槛梁2和安装侧梁3均沿第二方向y延伸，第二方向y垂直于第一方向x。延伸部32和第一主体部21上均沿第二方向y间隔设置多个安装孔322，螺母板6包括沿第二方向y间隔设置的多个螺母接口62，紧固件7依次穿过延伸部32和第一主体部21各自的安装孔322与相应的螺母接口62连接。例如，紧固件7可以为螺钉或螺栓等。
可选地，螺母板6与第一主体部21之间可设置垫片8。垫片8沿第二方向y可间隔设置多个通孔81。
例如，螺母板6可包括基板61和沿第二方向y间隔设在基板61上的多个螺母接口62，螺母接口62可以为设有螺纹孔的柱状结构，螺母接口62沿第三方向z位于基板61远离延伸部32的一侧，紧固件7可从下至上依次穿过延伸部32的安装孔322、第一主体部21的安装孔322、通孔81和螺母接口62。
该实施例通过紧固件7将门槛梁2与安装侧梁3可拆卸地连接，可提高装配或拆卸的便捷性，且能保证两者的连接强度。
在一些实施例中，如图3和图4所示，第一主体部21与延伸部32之间设有凹凸配合结构，并在凹凸配合结构处连接。例如，在凹凸配合结构处通过紧固件7实现可拆卸连接。
例如，如图5所示，第一主体部21朝向延伸部32的一侧设有第三凸起部211，延伸部32朝向第一主体部21的一侧设有第三凹入部321，第三凸起部211嵌入第三凹入部321中，以形成凹凸配合结构。
该实施例通过在第一主体部21与延伸部32之间设置凹凸配合结构，使第一主体部21与延伸部32之间交错设置，可增强门槛梁2与安装侧梁3连接后的整体弯曲刚度和弯曲模态。
在一些实施例中，第一主体部21与延伸部32之间在连接处之间设置有粘接层9。 例如，粘接层9可以是胶等具有粘性的物质形成的层结构，或者为了提高密封效果也可采用密封胶。例如，粘接层9可设在第三凸起部211与第三凹入部321之间。
该实施例通过在第一主体部21与延伸部32之间的连接处设置粘接层9，能够在安装紧固件7时防止门槛梁2与安装侧梁3之间发生位置错动，并提高提高第一主体部21与延伸部32连接的可靠性，还可提高连接的密封性。
