具体实施方式
为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明提出的车辆空调管固定装置的具体实施方式、结构、特征及其功效，详细说明如后。
需要注意的是，本发明的车辆空调管固定装置并非仅限于应用到电动车辆，而是可以应用到各种具有空调系统或空调管路10的车辆。
请参阅图1、图2、图3、图4、图5和图6，根据本发明示例的车辆空调管固定装置主要包括车身骨架件，该车身骨架件设有第一容置空间21，可以是空腔、凹槽或空隙，用于容纳空调管路10的至少一部分。进一步的，该车辆空调管固定装置还可包括空调管支架30，空调管支架30能容置于该车身骨架件的第一容置空间21内，空调管支架30的长度方向与第一容置空间21的长度方向一致，该空调管支架30设有第二容置空间，用于容纳和支撑空调管路10的至少一部分。可选的，空调管支架30的材料可以是塑料材质。
需要注意的是，根据空调管路10布局的位置，该车身骨架件可以采用具有空腔、凹槽或空隙的各种骨架件。在一些实施例中，该车身骨架件包括车辆的门槛梁20，例如可以是位于车辆侧门下方的门槛梁20，该门槛梁 20内设有能够容纳空调管路10的空腔。以下的实施例主要以设有第一容置空间21的门槛梁20作为车身骨架件的示范，以更好的说明本发明。
另外需要注意，这里所说的空调管支架30的长度方向与第一容置空间21的长度方向一致，并非指的是空调管支架30长度方向一定与第一容置空间21长度方向完全相同，而只是便于说明空调管支架30与第一容置空间21的位置关系，可将这里的方向一致理解为：将空调管支架30的长度方向定义为第一容置空间21的长度方向。类似的，第一容置空间21的长度方向并非一定与车身骨架件的长度方向完全相同。事实上，空调管支架30和第一容置空间21的位置和方向均可以根据实际布置情况来设置，例如，车身骨架件、第一容置空间21、空调管支架30三者的长度方向之间，既可以完全相同，也可以相互具有一定的角度。
在一些实施例中，空调管路10包括第一空调管路11、第二空调管路12和用于连接第一空调管路11和第二空调管路12的管路对接结构13。
该第一空调管路11能容置于门槛梁20内。第一空调管路11包括高压管和低压管。第一空调管路11可为直管，也可根据空调管支架30的形状或门槛梁20的形状而有所弯曲。
该第二空调管路12的主体不容置于门槛梁20内。第二空调管路12包括高压管和低压管。该第二空调管路12的用于与第一空调管路11连接的连接处可具有近似于“L”型的弯折部分，以适应车辆门槛处的造型。另外，可将第二空调管路12的该“L”型的连接处容置于门槛梁20内，以保护该连接处。
该管路对接结构13可采用任意的能够对接空调管路10的结构，例如该管路对接结构13可以是管路压板，包括与第一空调管路11连接的第一接头以及与第二空调管路12连接的第二接头，该第一接头与该第二接头能通过螺栓和螺母紧固在一起。
可选的，由于门槛两端离轮胎较近，并且为了将第二空调管路12与第一空调管路11对接的部分设置在门槛梁20内，可将第一空调管路11的长度设置得短于门槛梁20的长度。在一种实施方式中，可将该第一空调管路11、第二空调管路12的该“L”型的连接处和该管路对接结构13这三者的长度设为：这三者在装配到一起之后的总长度大致等于门槛梁20内的第一容置空间21的长度，从而能将上述三者同时布置在第一容置空间21内，以使管路的对接位置也能受到门槛梁20的保护。
在一些实施例中，该空调管支架30设有至少两个第二容置空间，用于容纳和支撑空调管路10的高压管和低压管的至少一部分。进一步的，空调管支架30还可设有位于这两个第二容置空间之间的空腔，以将这两个第二容置空间被该空腔分隔开。
空调管支架30的第二容置空间可以是径向截面与空调管路10外壁相吻合的通孔，使该空调管支架30能套设于空调管路10之外；或者该第二容置空间也可以是槽状的或腔状的，用于容纳空调管路10。
在一些实施例中，尤其是在第二容置空间为槽状或腔状的一些示例中，空调管支架30还包括设置于第二容置空间内的限位部，该限位部能与空调管路10相抵靠，以阻止空调管路10进行径向移动(在垂直于空调管路10长度方向的移动)。例如，该限位部可包括设置于第二容置空间内壁的凸起，在空调管路10的圆周方向上，通过凸起和第二容置空间内壁共同对空调管路10的径向位置进行限定，或者通过多个凸起对空调管路10的径向位置进行限定，以阻止空调管路10进行径向移动。进一步的，通过在第二容置空间内壁设置凸起，在空调管路10的圆周方向上，第二容置空间的内壁和/或凸起至少在三处与空调管路10相抵靠，不妨将与空调管路10相抵靠之处称为限位处。在周向上，如果这些限位处与空调管路10为点接触，则应至少有三个限位点不同时位于半个圆周内，从而能够阻止该空调管路10进行沿该空调管路10径向的移动。另外，在周向上，如果第二容置空间的内壁和/或凸起与空调管路10的外壁为面接触，也可以设置两个限位处。
可选的，空调管支架30的长度可短于门槛梁20的长度，也可短于第一空调管路11的长度，以节省空间、节省材料，并便于第一空调管路11与第二空调管路12的对接；如果布置空间充裕或者上述安排导致安装不方便，空调管支架30的长度也可不短于门槛梁20的长度。
具体的，请同时参阅图3和图4，在一种实施例中，空调管支架30包括平行设置的两个板状件，不妨将这两个板状件称为第一侧板31和第二侧板32。这两个侧板的长度方向、门槛梁20内的第一容置空间21的长度方向以及第一空调管路11的长度方向相一致。这两个侧板的长度略短于第一空调管路11的长度，并短于门槛梁20的长度。
第一侧板31和第二侧板32间隔的距离不小于第一空调管路11的直径，以能够容纳第一空调管路11；可选的，该间隔可以等于第一空调管路11的高压管和低压管中直径较大者的直径。
第一侧板31与第二侧板32之间通过隔板33连接，具体的连接方式可以是一体成型的固接。可以仅设有一个隔板33，从而第一侧板31、第二侧板32和隔板33之间形成有两个槽状的第二容置空间，用于容纳第一空调管路11的高压管和低压管；也可以设置两个隔板33，从而第一侧板31、第二侧板32和两个隔板33之间形成有两个槽状的第二容置空间以及位于该两个第二容置空间之间的空腔，该空腔用于将空调高压管、空调低压管分隔开一段距离；或者也可以设置更多的隔板33，从而形成腔状的第二容置空间或形成更多的第二容置空间。
需要注意的是，上述的第二容置空间以及用于形成第二容置空间的侧板31、隔板33的形状、尺寸、数量，可根据空调管路10的形状、尺寸、数量的不同而不同。
在每个第二容置空间内设有两个限位部，由第一侧板31和第二侧板32朝向该第二容置空间内弯折而形成，该限位部与第一空调管路11的外壁相抵靠，并且该限位部设置在与组成该第二容置空间的隔板33的距离大于第一空调管路11半径且小于第一空调管路11直径之处。从而通过第一空调管路11同时与这两个限位部和隔板33这三者的抵靠，能够阻止第一空调管路11进行径向移动。
需要注意的是，当空调管支架30具有两个或更多个第二容置空间时，在将空调管支架30容纳于车身骨架件内后，空调管支架30的多个第二容置空间的相对位置是任意的，并非必须为如图6所示的纵向排列，也可为横向排列或者倾斜排列，具体的排列方式可依据车身骨架件或车身骨架件内的第一容置空间21的形状、尺寸而决定。另外，在空调管支架30具有两个纵向排列的第二容置空间的实施例中，可用这两个第二容置空间中的任意一个空间放置高压管，另一个空间放置低压管。
可以采用多种方式来实现车身骨架件与空调管支架30的连接以及对空调管支架30的支撑，例如：
在一些实施例中，可以将车身骨架件内的第一容置空间21设为形状与空调管支架30外表面结构相吻合的通孔，使空调管支架30能够可拆卸的套接于第一容置空间21内。
在一些实施例中，可以将空调管支架30与第一容置空间21通过螺纹连接，使空调管支架30能够可拆卸的固定于第一容置空间21内。
在一些实施例中，第一容置空间21的内壁设有支撑件，用于支撑空调管支架30；例如该支撑件可以是设于第一容置空间21的沿第一容置空间21长度方向延伸的筋条22。空调管支架30的长度方向与第一容置空间21的长度方向一致。空调管支架30具有与第一容置空间21内壁或支撑件相抵靠的顶端或相贴合的贴合面，以接受第一容置空间21内壁和支撑件的支撑；例如可以是空调管支架30具有板状件，该板状件具有与作为支撑件的筋条22相贴合的贴合面以及与第一容置空间21内壁相抵靠的顶端，或者通过在该板状件上设置朝向筋条22延伸的翻边34，使翻边34具有与筋条22相贴合的贴合面以及与第一容置空间21内壁相抵靠的顶端。通过第一容置空间21内壁、支撑件对空调管支架30的接触，在垂直于该长度方向，该支撑件能够限制空调管支架30的移动。进一步的，为了提供稳定的支撑和限制空调管支架30的移动，空调管支架30与第一容置空间21内壁或支撑件在多个支撑位置相抵靠或相贴合，在第一容置空间21的圆周方向上， 可以至少有两个支撑位置位于第一容置空间21的径向两端，或者可以至少有三个支撑位置不同时位于半个圆周内；例如可将支撑件对称的设置在第一容置空间21的面对面设置的一对内壁上。需注意，在本示例中，如果在第一容置空间21周向上成对的设置支撑件，例如在第一容置空间21的面对面的一对内壁中的每一侧均设置相互平行的两根筋条22，则也可将每对支撑件(每两根筋条22)、空调管支架30上与每对支撑件接触的部件或侧壁，分别视为滑槽和该滑槽的配合件。
具体的，请同时参阅图4、图5和图6，在一种实施例中，空调管支架30包括相互平行且间隔设置的两个板状件，不妨将这两个板状件称为第一侧板31和第二侧板32，第二容置空间位于第一侧板31第二侧板32之间。这两个侧板的长度方向与第一容置空间21的长度方向相一致。第一侧板31的宽度方向的两端设有向远离第二侧板32方向翻折(不妨称为向外翻折)的翻边34，使第一侧板31的外表面形成为沿第一容置空间21长度方向延伸的第一滑槽，第二侧板32的宽度方向的两端设有向远离第一侧板31方向翻折(不妨称为向外翻折)的翻边34，使第二侧板32的外表面形成为沿第一容置空间21长度方向延伸的第二滑槽。门槛梁20的第一容置空间21内设有第一滑槽的配合件以及第二滑槽的配合件，每个配合件包括在第一容置空间21的内壁上间隔且平行设置的两个筋条22，这两个筋条22的长度方向与第一容置空间21的长度方向一致，这两个筋条22的彼此相背的两个侧壁(可称为配合件外壁)能同时与滑槽内壁进行面接触而相贴合，使配合件能容纳于滑槽内。需注意，该滑槽与该配合件进行配合时，翻边34的排布方向与筋条22的排布方向相平行，或者说，翻边34的高度方向与筋条22的高度方向相平行。并且将筋条22的位置和高度设为使第一滑槽、第二滑槽能够同时与对应的配合件相配合，从而空调管支架30能够滑入门槛梁20的第一容置空间21内，并受到门槛梁20的支撑(也意味着阻止了空调管支架30沿图6中的竖直方向的移动)。
可选的，第一侧板31的两个翻边34中的至少一个的顶端以及第二侧板32的两个翻边34中的至少一个的顶端，能够同时与第一容置空间21内壁相抵靠，以阻止空调管支架30沿图6中的水平方向的移动，从而能够将空调管支架30在第一容置空间21内的移动限制为仅能进行沿筋条22长度方向的移动。或者，也可选用过盈配合或粘合等方式实现空调管支架30与门槛梁20之间的连接，以阻止空调管支架30在第一容置空间21内的移动。
需注意，在沿第一容置空间21长度方向上，每个筋条22可以是贯通于第一容置空间21的一条，也可以是沿同一直线的间断的多条。
需注意，作为一个配合件的筋条22的数量不作限定，在一个示例中，可利用能容纳在滑槽中的足够宽的一根筋条22作为滑槽的配合件，来代替 两根筋条22。
需注意，滑槽并不限于通过在侧板设置翻边34来形成。例如在一种示例中，空调管支架30包括平行设置的两个板状件(第一侧板31和第二侧板32)，第二容置空间位于这两个板状件之间，这两个板状件的沿宽度方向的一端的相对的两个侧壁形成为第一滑槽，另一端的相对的两个侧壁形成为第二滑槽，板状件在宽度方向上朝向第一容置空间21内设置的筋条22延伸(或者说，板状件的宽度方向与筋条22的高度方向相平行)，且这两个滑槽能与筋条22进行面接触而相配合，使门槛梁20能容纳和支撑该空调管支架30。进一步的，两个板状件的沿宽度方向的两端的顶端可与第一容置空间21内壁相抵靠。
在一些实施例中，也可利用设于第一容置空间21的面对面的一对内壁上的筋条22形成滑槽：每一内壁上的筋条22具有两组，且沿所在内壁的宽度方向相互平行地间隔设置，相互平行的筋条22之间形成滑槽，而空调管支架30上设有能容纳于该滑槽中的配合件。例如可以对如图6所示的示例进行调整，使空调管支架30的侧板的两个翻边34的彼此相背的两侧壁能同时与位于第一容置空间21内壁一侧的两个筋条22的彼此相对的两侧壁进行面接触，这时这对筋条22之间形成为滑槽，空调管支架30侧板的两个翻边34形成为配合件。需要注意的是，在本示例中，空调管支架30上设置的配合件是否为板状件以及配合件的数量都不限定，仅需配合件能够容纳在滑槽中，并使空调管支架30受到门槛梁20的稳定支撑即可。
而在一些实施例中，也可以仅在平行的两个板状件的沿宽度方向的一端设置翻边34，使空调管支架30的径向截面呈“T”字型；在第一容置空间21内壁上，在“T”字型的三端的对应位置设置筋条22，以在垂直于第一容置空间21长度方向，阻止空调管支架30的移动。
另外需注意，从另一个视点观察本实施例时，也可将每个筋条22视为第一容置空间21内壁设置的支撑件，而将与筋条22面接触的翻边34或将与筋条22面接触的板状件侧壁视为支撑件的配合件，通过支撑件与配合件之间的面接触并通过板状件的顶端与第一容置空间21内壁的抵靠，来阻止空调管支架30在第一容置空间21内进行沿垂直于第一容置空间21长度方向的移动。
以上所述，仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但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做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
