Description

用于多线槽连接的布线结构 技术领域
本发明涉及一种用于多线槽连接的布线结构，应用于汽车线束安装领域，尤其涉及一种具有柔性的用于多线槽连接的布线结构。
背景技术
近年来，随着温室效应的加剧，各行各业对环保方面提出越来越多的要求。当然，汽车行业也不甘示弱，积极开发和推出新能源车辆，诸如电动车辆(EV)、混合动力车辆(HEV)，由此以缓解石油为燃烧原料的现有常规车辆带来的环境问题。
诸如电动车辆、混合动力车辆等新能源车辆由于采用电力驱动，需设置高压电缆线束，且需要承载大规模蓄电设备以及与其相配合的线束布置。在线束布置方面进行优化，可大大节省空间、减少成本、提高安装方便度，因此，受到了空前的关注度。
目前，在线束布置方面，常规采用的方式有：多个支架一同安装在车辆底部保护线束，所有的支架通过卡槽结构一个接一个连接在一起。用于制作支架的材料往往是刚性的材料，诸如塑料，不具有柔性。此外，这些支架通过卡槽彼此连接，这种连接方式提供无缝连接，即，连接后彼此是固定的，无法弯折。因此，这种具有卡槽结构的布线结构在车辆内部安装时，带来诸多不便，很难消除安装公差，而且精度不高，可能造成空间的浪费。诸如，若要安装在有弯曲角度的狭小空间，有时不得不采取具有与该空间匹配的形状的另外的支架。
此外，多个支架通过卡槽连在一起会形成长形的串联支架，由于是卡槽结构，无法折叠，无法弯曲，导致运输困难。
发明内容
鉴于车辆内线束布置中存在的诸多问题，本公开的用于多线槽连接的布线结构 在特定部位具有柔性，可具有线束方便安装、消除安装工差、运用广泛、运输方便等优点。
根据本申请的一实施方式，提供一种用于多线槽连接的布线结构，用以在车辆底部安装保护线束，其特征在于，该布线结构包括：多个支架(1、3)，所述支架分别具有2个端部，彼此相邻设置的2个支架的端部之间设有间隙(6)；至少一个线束(2)，设置于所述支架内部，且贯穿多个所述支架来延伸；套管(4)，具有柔性且设于所述线束的外周，在轴向上所述套管重叠于所述间隙。
优选地，所述套管(4)具有柔性。
进一步优选地，所述套管(4)为抗冲击护套。
优选地，在穿过所述支架(1、3)中心线的截面上，所述支架的端部呈梯形，越靠近端部末端越宽。
优选地，所述支架(1、3)的端部形成有突边(5)。所述支架(1、3)的端部的所述突边(5)在垂直于所述支架轴向的截面上呈连续的环形。或者，所述支架(1、3)的端部的所述突边(5)在垂直于所述支架轴向的截面上呈不连续的环形。
此外，优选地，所述支架(1、3)的外周设有至少一个扎带孔(7)，用以通过绑定保护线束扎带。
根据本申请的一实施方式，所述支架(1、3)的制作材料为塑料。
优选地，所述支架(1、3)的端部呈现的梯形截面的长边宽度为5-50mm。
根据另一实施方式，所述支架(1、3)上还设有用以保护和固定保护线束的封盖。
此外，优先地，所述间隙(6)在平行于所述支架的轴向的方向上的宽度为5-10mm。
通过形成上述结构，与现有技术相比，本申请的用于多线槽连接的布线结构具有以下优点：
1)线束方便安装：本发明的结构在线槽盒盒盖打开状态下，支架内部有足够的空间安装线束；
2)消除安装工差：由于两个相对设置的支架间没有直接连接或卡住，并且支架与支架间的间隙采用软质的抗冲击护套，不仅可以有效的保护露出支架间隙处的线束，同时可以进行活动，能够调整安装位置和角度，提高安装精度；
3)运用广泛：本发明能够适用于不同类型的车底部的保护线束的安装。
4)运输方便：本发明结构简单并且可以分别进行串联折弯安装，便于运输。

具体实施方式
下面结合具体实施例和附图对本发明作进一步说明，在以下的描述中阐述了更多的细节以便于充分理解本发明，但是本发明显然能够以多种不同于此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下根据实际应用情况作类似推广、演绎，因此不应以此具体实施例的内容限制本发明的保护范围。
接下来，结合附图和具体实施例对本发明进行详细说明。在说明过程中，为了突出本申请的布线结构的特点，有时对本领域普通技术人员公知的部分进行了省略 处理或简化处理。
首先，参照图1和图2对现有技术进行简单说明，以便于更好地理解本申请所涉及的技术方案及通过该技术方案带来的技术效果。图1为现有技术的用于多线槽连接的布线结构的大致外观图。图2为突出示出现有技术的用于多线槽连接的布线结构的局部放大图。
图1中可观察到多个支架一个接一个地连接在一起，形成长条形的布线结构，在各支架中收纳有线束，各线束跨越多个支架形成长条状。形成长条的多个各支架彼此之间没有空隙，它们的连接是紧密的。
图2是突出示出图1中的2个支架之间的连接部位的局部放大图，图2是对图1中用圆圈全出的局部的放大图。可以观察到2个支架之间的连接是由卡槽结构实现的。在图2的上方和下方各自示出了1个卡槽结构，一个支架形成有耳朵形状的弯钩，另一个支架形成有突边，突边可以卡进弯钩中。这种卡槽结构是刚性结构，连接后的多个支架不易弯曲、不易折叠，在安装方面容忍度较低，空间利用率受影响，且运输方面也有诸多不便。例如，在车辆的大致呈90度的角隅部分进安装该用于多线槽连接的布线结构时，有可能需要引进与该角度相匹配另一形状的支架，可参见图1的右边部分的呈弧形的支架。可以说，要提高空间利用率，则往往需要引进多种形状的支架，以便完美地匹配已有车辆内的空间形状。这不仅对支架的成型提出更高的要求，制造成本提高，安装时也要经常考虑不同的安装条件，选择不同形状和尺寸的支架，给安装工程师也带来了诸多不便。
在知晓上述现有技术的布线结构中存在的问题的基础上，参照后续的附图(图3-图8)来说明本申请的实施方式的布线结构。通过与现有技术中采用的结构相比较，可以更清晰地分辨出本申请的技术改进及其带来的技术效果。
接着，参照图3和图4，对本申请的实施方式的用于多线槽连接的布线结构进行说明。图3为根据本申请的一实施方式的用于多线槽连接的布线结构的大致外观图。图4为突出示出根据本申请的一实施方式的用于多线槽连接的布线结构的局部的放大图，图4是图3中用圆圈圈出的局部进行放大得到的图。
在图3的外观图中，由多个支架(第一支架1、第二支架3……)构成的布线结构大致呈长条形，各支架之间设置有间隙以便将彼此间隔开。在该长条形布线结构的外周，形成有至少一个扎带孔7，用以通过绑定保护线束扎带。图示中，各支架具有2个端部，且端部在平行于支架轴向的方向上的截面呈大致梯形，此截面是 穿过支架中心线的截面。靠近支架最末端的边为梯形的长边，相对靠近支架中心的边为梯形的短边，即，越是靠近支架末端，端部开口越宽，靠近支架中心，端部逐渐变窄。
此外，从图3中可以看出相邻设置的2个支架之间设有间隙，2个支架并非是无缝连接。由于该间隙的设置，本申请的实施方式的多个支架在彼此相连后，仍然可提供柔性，便于弯曲、便于则叠，由此提高安装方便度，且运输方面也得到了较多有益效果。
接着，参照图4，对彼此相连的2个支架的连接部位进行详细说明。将图4中左侧的支架命名为第一支架1、右侧的支架命名为第二支架2，本领域普通技术人员将理解第一支架、第二支架并非用来限定支架之间的前后关系或先后顺序，仅仅是为了便于说明。在第一支架1、第二支架3之间设置有间隙6。换言之，第一支架1、第二支架3并非是开槽结构或刚性结构。图4中的间隙6表示具有宽度d，该宽度是2个支架彼此间隔开的距离，也可称之为间隙宽度。
此外，在图4中的附图标记“2”表示线束，第一支架1、第二支架3中可收纳有至少1条线束2，线束的具体数量并非是限定性的，可根据需要设置合适的数量，图3中示出了3根线束。线束2穿过第一支架1、间隙6以及第二支架3来延伸，在各线束2的外周设置有套管4，可称为套有套管4。套管4由软质的材料制成，用来保护线束2。软质的套管4不仅给布线结构带来充分的柔性，同时又能给线束提供足够的保护。
根据本申请的一实施方式，套管4可以采用抗冲击护套，具体地，可以采用辉门公司研发出的高压电缆保护产品，商标名称为CrushShield TM的新型材料。作为电动车辆、混合动力车辆(EV/HEV)的高压电缆的防护屏蔽材料，CrushShield TM可环绕在电缆周围使电池电缆与汽车的执行结构隔离，且具有坚固、多层的纤维材质与独特的基地设计，它们共同吸收并分散冲击力。诸如，可分散碰撞时产生的剪切力。
当然，套管4的材料可以是对车辆线束提供充分的保护且足够的柔软度的其他材料，不限于本文所提及的特定材料。只要满足上述条件即可。可以是市面上在售的任何一种柔性材料。
继续参照图4，在各支架的端部、即2个支架(1、3)之间形成的间隙6附近，形成有突边5。图4为支架连接部位的穿过支架中心线的截面图，在该截面图中， 突边5呈现为突起的方块，且设置于支架端部的最末端。实际上，突边5形成在支架的外周，是从支架内侧向支架外侧径向突出的结构。突边5的形状及其设置方式可以是多种多样的。举例来讲，若支架为圆形，突边5可能是连续的环形，在支架的整个外周上连续地形成。突边5还可能是不连续的环形，在支架的外周形成多个断开的突边5，即，各突边5彼此之间设有间隔，如一个个孤立的小岛。通过在支架的端部设置突边5，可起到防止磨损的效果。此外，由于设有突边5，在安装时将2个支架彼此对准可以更方便，精确度更高。
此外，参见图3和图4，本申请的实施方式的支架的末端形成为靠近末端更宽的形状，这种结构有助于设置套管4。如上所述，套管4的设置位置与间隙6相重叠，且套管4的轴向长度略大于间隙6的轴向长度“d”。该间隙6的轴向长度d可以在5-10mm的范围中。由于增加了套管4，支架的设置套管4的部位尺寸将大于其余的只有线束的部位尺寸，这有利于线束的排线，提高可靠度。假设支架形成为统一的尺寸，如同圆柱那样在长度方向上具有相同的直径，则会导致仅设置线束的空间内的线束布置松散，这对可靠性是不利的。但本申请通过采用端部末端更宽的结构，简便地解决了上述问题，将支架的设置套管4的部位形成为较宽，不设有套管4的部位形成为较窄。
优选地，根据本申请的一实施方式的用于多线槽连接的布线结构，在穿过中心线的所述支架的端部截面中，梯形长边的长度为5-50mm。
此外，根据本申请的一实施方式的用于多线槽连接的布线结构，支架上可设有封盖(未在图中示出)，将线束包裹在支架内部以保护和固定。
接着，参照图5，对本申请的实施方式的线束和套管的关系进行说明。图5的线束和套管的线束轴向上的截面图。图5的附图标记“2”表示线束，用阴影表示，“4”表示套管。为了避免本实施方式的改进点变得模糊，图中仅仅是示意性地示出了套管4和线束2。如图所示，套管4设置于线束2的外周以便保护线束2。当然，套管4的形状可根据线束2的形状而变化。当线束2为圆形时，套管4呈环形，线束2和套管4形成同心圆。当线束2为扁平线时，套管4可呈椭圆形。对线束2的形状和套管4的形状不作任何限定，只要套管4设于线束2外周且能保护线束2即可。此外，由于套管4设于线束2的外周，在支架的设有套管4部分处的尺寸相应地增大。要注意，套管4的位置与2个支架的端部之间的间隙6相重叠。由此，不仅提供柔软度，还能提供可靠度，兼顾了安全和性能。
图6为从垂直于轴向的方向上贯穿的套管和线束的截面图。图6中阴影部分为线束2，没有阴影的空白部分为套管4。图示结构为圆形的线束2以及与其对应的环形的套管4。线束2设于中心，套管4设于线束的外周，此时线束和套管形成了同心圆。当然，本申请不旨在限定线束与套管的形状。仅仅是示意性地示出了套管与线束的相对关系。
下面，参照图7-8，继续讨论本申请的实施方式的线束与套管安装后的示意图。图中阴影表示的部分是线束2，没有阴影的部分是套管4。图7示出的是设置于弯曲的空间中的布线结构示意图。例如，当弯曲空间形成的角度大约为90度，且需要在这种弯曲的空间安装该布线结构时，可以不采用专门的适用于弯曲部分的支架，而是通过套管4的柔软性，将布线结构弯曲即可。专门的适用于弯曲部分的支架将造成成本的提高，这是不希望采用的方式。本申请的用于多线槽连接的布线结构通过利用间隙及其相应部分的套管，减少了制造不同形状支架所需的模具种类。通过简化制造方法，可降低制造成本，且还能提高安装容易度。
图8是另一实施方式的线束与套管安装后的示意图。图中阴影表示的部分是线束2，没有阴影的部分是套管4。图8示出的结构是将布线结构安装于如“之”字形的空间中的示意图。同图7的实施方式一样，可以不采用专门的适用于“之”字形弯曲部分的支架，而是通过套管4的柔软性，将布线结构沿着要安装的空间弯曲即可。专门的适用于“之”字形部分的支架将造成成本的提高，这是不希望采用的方式。本申请的用于多线槽连接的布线结构通过利用间隙及其相应部分的套管，减少了制造不同形状支架所需的模具种类。通过简化制造方法，可降低制造成本，且还能提高安装容易度。
图7、图8所示的上述2个实施方式仅仅是为了说明本发明的用于多线槽连接的布线结构而采用的示意性结构，本领域普通技术人员可根据需要，以各种不同方式弯折支架，尤其是受益于支架连接处的间隙所形成的柔软结构特征，将布线结构与各种不同形状匹配，可节省布线结构所占据的空间，提高布线结构的安装方便度，节省成本，进而可普遍利用于电动车辆、混合动力车辆等新能源车辆中。
此外，本领域普通技术人员将理解尽管图7、图8仅仅示出了一根线束和套管，但这只是说明性的，多根线束存在的情况下，也能实现相似的安装。线束和套管的数量并非是限定性的。
简言之，本发明的原理如下：
第一支架1和第二支架3之间留有一定的间隙，即，2个之间的连接并非是无缝连接，对该间隙处的线束使用抗冲击护套保护，即，软质套管，诸如CrushShield  TM。当整个支架链在安装到车上时，可以利用套管较软的特性，来回移动，这样就可以较为方便地消除整个车身与支架的安装公差，使得支架的安装变得较为方便，此外由于套管较软，整个之间链可以折弯，这样也便于运输。
本公开虽然以较佳实施例公开如上，但其并不是用来限定本发明，任何本领域技术人员在不脱离本发明的精神和范围内，都可以做出可能的变动和修改。因此，凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何修改、等同变化及修饰，均落入本发明权利要求所界定的保护范围之内。
