Description

具有集成管路的梁组件和包括该梁组件的车辆 技术领域
本发明属于汽车零件领域，具体提供一种具有集成管路的梁组件和包括该梁组件的车辆。
背景技术
纵梁是车架的关键零件之一，在汽车上起到重要的承载作用。一般的汽车设计方案中，纵梁和管路系统是分开的，需要单独设计开发，并且装配。不仅占用整车的布置空间，同时，需要更多的设计、开发、生产、装配和维修的环节，产生生产问题的环节多，开发和维护成本高。
为了节省汽车的布置空间、降低生产成本，需要将纵梁的结构优化。目前，纵梁的断面形状一般为槽型、Z字型和箱型，且根据汽车形式的不同和结构布置的要求，纵梁可以在水平面内或纵向平面内做成弯曲、等断面或非等断面的，从而满足承载需求。但考虑到设计过程中除纵梁的设计方案外还需单独确定管路系统的设计方案，二者不仅需要分步组装，独立布置的纵梁结构和管路系统还占用了较大的空间，增加了生产成本。
相应地，本领域需要一种新的梁结构来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有汽车设计方案中纵梁不能与管路系统结合，使得布置空间占用大、生产成本高的问题，本发明提供了一种具有集成管路的梁组件。该具有集成管路的梁组件包括梁以及形成在所述梁中的至少一个空腔，所述空腔能够与外部连通，使得流体能够从所述空腔流到外部或者从外部流入所述空腔。这里的“外部”优选地是外部管路或管道，但也可以是需要流体流通的其他任何外部系统，该系统可以与空腔的任一端或两端连通。
在上述具有集成管路的梁组件的优选设计方案中，所述梁组件还包括第一转接头，所述第一转接头的一端与所述空腔的一端相连，所述第一转接头的另一端连通到外部，使得所述空腔借助所述第一转接头与外部连通。
在上述具有集成管路的梁组件的优选设计方案中，所述梁组件还包括第二转接头，所述第二转接头的一端与所述空腔的另一端相连，所述第二转接头的另一端也连通到外部，使得所述空腔借助所述第二转接头与外部连通。
在上述具有集成管路的梁组件的优选方案中，所述梁组件还包括密封层，所述密封层通过涂覆工艺形成在所述空腔、所述第一转接头和所述第二转接头的至少部分内表面上。
在上述具有集成管路的梁组件的优选设计方案中，所述空腔内设置有至少一条内部管道。作为本发明的另一个实施方式，当所述空腔内设置有内部管道时，上述“所述空腔能够与外部连通”意指所述内部管道直接与外部连通，所述空腔借助内部管道间接地与外部连通。并且，上述“流体从所述空腔流到外部或者从外部流入所述空腔”意指流体从所述内部管道流到外部或者从外部流入所述内部管道。
在上述具有集成管路的梁组件的优选设计方案中，所述梁组件还包括第三转接头，所述内部管道的一端与所述第三转接头密封连接。
在上述具有集成管路的梁组件的优选设计方案中，所述梁组件还包括第四转接头，所述内部管道的另一端与所述第四转接头密封连接。
在上述具有集成管路的梁组件的优选设计方案中，所述密封层设置成能够实现有效密封并且能够保护所述空腔、所述第一转接头和所述第二转接头的内表面。
在上述具有集成管路的梁组件的优选设计方案中，所述梁是车辆的车身纵梁。
根据另一个方面，本发明提供一种车辆，该车辆包括上述任一种具有集成管路的梁组件。
本领域技术人员能够理解的是，在本发明的技术方案中，梁的内部设置有空腔，用于设置集成管路，因此管路系统直接与梁组 件相结合，不仅能够实现二者的一步装配，还能大幅度提高整车布置空间的利用率，同时，减少了管路系统的设计步骤。换句话说，本发明将现有技术中“独立的纵梁和管路系统”改造成了“具有集成管路的梁组件”，极大地缩小了纵梁和管路系统占用的布置空间，降低了生产成本。
附图说明
图1是本发明的具有集成管路的梁组件中的梁的侧面剖视图。
图2是本发明的具有集成管路的梁组件的第一实施方式的局部结构剖切图。
图3是本发明的具有集成管路的梁组件的第二实施方式结构图。
具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，尽管说明书中是选取一个空腔来描述的，但是，本发明可以采用的空腔数目显然不仅限于一个，与之配合的转接头数目也不仅限于两个，同理，密封层也不仅限于一处，只要在保证纵梁的承载能力的同时能满足管路系统的设计需求即可。此外，尽管本申请以车身纵梁为例进行描述，但是这并不构成对本发明的限制，本发明的技术方案也可以应用于其他梁结构，例如车身横梁。
需要说明的是，在本发明的描述中，术语“中”、“左”、“右”、“内”等指示的方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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。
此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“相连”、“连接”“安装”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；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。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
首先参阅图1，该图为具有集成管路的梁组件中的梁的侧面剖视图。如图1所示，本发明的具有集成管路的梁组件包括梁1以及形成在梁1中的若干空腔，其中一个或者多个空腔可以作为管路与外部(包括但不限于外部管路系统)连通。作为示例，图1中将标号2所示空腔作为管路。优选地，梁1采用挤压成型工艺制成，在挤压成型时形成空腔2。作为示例，空腔2是等截面的方形空腔。关于此点，需要指出的是，上述空腔2的截面形状可以根据具体应用对象的需求来设计，不仅限于方形或者常规的圆形。此外，尽管图1中将空腔2描绘成位于梁1的左下角，但是，这种位置的选取仅仅是示例性的，并不构成对本发明的限制，本领域技术人员可以根据需要(例如散热要求)将空腔2设置在梁1中的其他位置，例如设置在梁1的中部。这种变化并不偏离本发明的原理，因此也将落入本发明的保护范围之内。
接下来参阅图2，图2为具有集成管路的梁组件的第一实施方式的局部结构剖切图。如图2所示，空腔2的左端连接有第一转接头3，优选地，采用挤铆的连接方式，使第一转接头3紧密压接在梁1的空腔2中，并且第一转接头3与外部管路的第一管道5相连。类似地，空腔2的右端连接有第二转接头4，并且第二转接头4与外部管路的第二管道6相连，即空腔2的两端分别通过第一转接头3和第二转接头4与外部管路的第一管道5和第二管道6相通，使流体能够在空腔2、第一管道5和第二管道6内流通。第一转接头3和第二转接头4的一端与空腔2的两端匹配，另一端分别与外部管路的第一管道5和第二管道6匹配，以便于实现第一管道5、第一转接头3、空腔2、第二转接头4和第二管道6间的密封连接。并且，两个转接头的整体弯曲程度可以根据实际设计调整，并不局限图2所示的形式。需要指出 的是，尽管这里是结合外部管路来描述的，但本发明并不局限于此，与空腔2连通的也可以是需要流体流通的其他任何外部系统。
继续参阅图2，在制作过程中，当梁1中的空腔2与第一转接头3或第二转接头4密封装配完毕，且测试其具备管路功能后，使流体状密封材料从第一转接头3的左端或第二转接头4的右端流入，经过空腔2后从第二转接头4的右端或第一转接头3的左端流出，使密封材料均匀地附着在空腔2、第一转接头3和第二转接头4的内表面上，形成密封层7。所选密封材料应具有一定的附着能力便于涂覆时形成均匀的密封层。此外，密封材料还应具备良好的耐腐蚀性，以便保护梁1内的集成管路的内表面，即保护空腔2、第一转接头3和第二转接头4的内表面。
接下来参阅图3，图3为具有集成管路的梁组件的第二实施方式的结构示意图。如图3所示，梁1中的空腔2内部安装有内部管道8，也就是说，空腔2不直接作为管路，而形成为供内部管道8穿过的空间。优选地，内部管道8的左端与第一转接头3密封连接，其右端与第二转接头4密封连接，且第一转接头3和第二转接头4的另一端分别与外部管路的第一管道5和第二管道6密封连接，使得内部管道8与外部管路的第一管道5和第二管道6相连，以便流体在其内部流通。此外，尽管本实施例中采用的内部管道8的数量为1根，但是，这仅仅是示例性的，也可以根据实际需要调整空腔2及内部管道8的数量。上述调整并没有偏离本发明的原理和范围。再者，内部管道8可通过各种适当的方式固定在空腔2中。例如，内部管道8可以与空腔2形成过盈配合并因此被固定在空腔2中，内部管道8也可以与空腔2形成间隙配合，并借助第一转接头3和第二转接头4固定到空腔2中。这种固定方式的变化不应对本发明的保护范围构成任何限制。另外，通常情况下内部管道8自身具有密封和防腐蚀功能，只需要将其与转接头3和4密封连接即可，但是，也可以根据需要采用第一实施方式中的涂覆工艺在内部管道8及其与转接头3和4的连接部位形成密封层，这些调整都不偏离本发明的原理和范围。
综上所述，上述两种实施方式均是通过在纵梁内部设置空腔的方式使纵梁内部形成集成管路，将管路系统与纵梁相结合，在保证纵梁原有的承载功能的基础上完成管路系统的设计方案，极大地缩 减了汽车的布置空间，节省了开发、设计、运输、装配以及维修等费用，具有很强的实用性和经济效益。
在上述方案的基础上，本发明还要求保护一种车辆，该车辆包括上述实施例中任一种具有集成管路的梁组件。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
