具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“中心”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两 个，三个等，除非另有明确具体的限定。
下面参考图1和图2描述根据本发明实施例的车辆的后横梁1与电机支架2的连接结构。
如图1和图2所示，根据本发明第一方面实施例的车辆的后横梁1与电机支架2的连接结构，其中后横梁1位于车辆的后端且后横梁1沿左右方向延伸，电机支架2设在后横梁1的前侧。可选地，上述车辆可以为汽车。
具体而言，连接结构包括螺纹套管3和螺栓4，螺纹套管3沿前后方向贯穿后横梁1并压铆在后横梁1上。由于螺纹套管3是通过压铆的方式连接在后横梁1上的，螺纹套管3与后横梁1接触的地方是靠过盈配合产生抗扭转力，从而可以将螺纹套管3稳固地连接在后横梁1上。电机支架2上形成有第一安装孔211，螺栓4穿过第一安装孔211并与螺纹套管3配合以将后横梁1和电机支架2连接。
可以理解的是，通过在后横梁1上设置螺纹套管3与螺栓4配合，这样螺栓4通过螺纹套管3与后横梁1配合，缩短了螺栓4与后横梁1的配合距离，可以减小螺栓4的长度。由此，在将螺栓4穿过第一安装孔211与螺纹套管3配合时，螺栓4在安装过程中所占据的空间小，使得安装更为方便，并且可以保证连接的强度和可靠性。
另外，通过上述的连接结构连接后横梁1和电机支架2，还具有降低能耗、减少烟尘排放的优点。
根据本发明实施例的车辆的后横梁1与电机支架2的连接结构，采用螺纹套管3贯穿后横梁1并压铆在后横梁1上，并通过螺栓4配合螺纹套管3连接后横梁1和电机支架2，该连接结构具有结构简单、安装方便、重量轻、降低能耗、减少烟尘排放的优点，同时可以保证连接的强度和可靠性。
下面参照图1和图2详细描述根据本发明实施例的车辆的后横梁1与电机支架2的连接结构。
参照图1和图2，后横梁1沿左右方向延伸，电机支架2设在后横梁1的前侧，且电机支架2为沿前后方向延伸的长条形。电机支架2的外周沿形成有翻边21，第一安装孔211形成在翻边21上。连接结构包括螺纹套管3和螺栓4，螺纹套管3压铆在后横梁1上，螺栓4可以穿过翻边21上的第一安装孔211与螺纹套管3配合，由此通过设置的翻边21使得安装更为方便。
参照图1和图2，螺纹套管3可以包括多个且多个螺纹套管3可以围绕电机支架2的周向间隔设置，螺栓4包括多个且分别与多个螺纹套管3一一对应连接。例如，在图1和图2的示例中，电机支架2的左右两侧形成有翻边21，第一安装孔211为四个且对称分布在电机支架2的左右两侧，螺纹套管3包括四个，对应地，螺栓4也包括四个，每个螺栓4 依次穿过对应的第一安装孔211与对应的螺纹套管3配合，从而可以将后横梁1和电机支架2稳固连接。
在本发明的一些实施例中，参照图2，后横梁1内具有空腔11，空腔11的后侧壁上形成有第二安装孔，空腔11的前侧壁上形成有第三安装孔，螺纹套管3沿前后方向贯穿空腔11且螺纹套管3的前端和后端分别配合在第三安装孔和第二安装孔内。由此，在安装螺纹套管3时，只需将螺纹套管3从后向前依次穿过第二安装孔、空腔11及第三安装孔，并通过压铆设备等施加的压力直接将螺纹套管3压铆在后横梁1上，安装方便且可以使螺纹套管3与后横梁1连接稳固。
可选地，螺纹套管3的横截面可以为非圆形。例如，螺纹套管3的横截面可以为六边形，或者螺纹套管3的外周面上可以设置滚花纹，防止螺纹套管3在安装时转动，提高连接的可靠性。
可选地，螺纹套管3、电机支架2和后横梁1中的至少一个为铝合金件。例如，可以仅将螺纹套管3设置为铝合金件，由此使得螺纹套管3具有强度高、重量轻的优点，从而可以进一步提高连接结构的强度，并可以减轻连接结构的重量。例如，也可以将电机支架2设置为铝合金件或者将后横梁1设置为铝合金件，例如电机支架2或后横梁1可以为挤压铝合金型材，由此使得电机支架2或后横梁1的成型工艺简单，且生产效率高。当然，还可以将螺纹套管3、电机支架2和后横梁1均设置为铝合金件。
另外，电机支架2和后横梁1为铝合金件时，通过采用上述的连接结构连接电机支架2和后横梁1，不仅可以保证连接的强度和可靠性，还可以解决铝合金的焊接困难问题。
在本发明的一些具体实施例中，参照图2，螺纹套管3包括头部31和与头部31连接的管体32，头部31与空腔11的后侧壁的后表面相抵，管体32邻近头部31的一端(参照图2中管体32的后端)与后侧壁压铆连接。可以理解的是，利用压铆连接的特点，管体32邻近头部31的一端与后侧壁压铆连接时，管体32的外周面与后侧壁配合的部分可以形成有齿状凸出，通过压力使螺纹套管3的齿状凸挤入后侧壁内并使第二安装孔的周边产生塑性变形，从而产生锁紧的效果。由此，可以保证螺纹套管3与后横梁1连接稳定且安装方便。
进一步地，管体32的远离头部31的一端(参照图2中管体32的前端)与第三安装孔过盈配合。由此，可以进一步使螺纹套管3与后横梁1稳定连接。例如，可以使第三安装孔的内径稍小于管体32的外径，在安装螺纹套管3时，可以利用压铆设备等对螺纹套管3的施加的压力使得管体32穿过尺寸较小的第三安装孔，从而可以使管体32与第三安装孔紧密配合。另外，管体32的前端的端面可以与后横梁1的前侧壁的前表面平齐，从而可以减少后横梁1与电机支架2之间的配合间隙，提高连接结构的稳定性和可靠性。
在本发明的进一步实施例中，参照图2，螺纹套管3的远离电机支架2的一端(参照图2中螺纹套管3的后端)封闭。由此，可以使连接结构具有良好的密封性，可以防止液体等流入螺纹套管3内腐蚀螺纹套管3，提高连接结构的可靠性。
根据本发明第二方面实施例的车辆，包括根据本发明上述第一方面实施例的车辆的后横梁1与电机支架2的连接结构。由此，可以使后横梁1与电机支架2可靠连接且安装方便，可以提高车辆的整体质量。
根据本发明实施例的车辆，通过设置上述的连接结构，可以将后横梁1和电机支架2可靠连接且安装方便，提高车辆的整体质量。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接或彼此可通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本发明的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本发明的限制，本领域的普通技术人员在本发明的范围内可以对上述实施例进行变化、修改、替换和变型。
