Description

模块化构造的塑料容器
技术领域
本发明涉及一种模块化构造的塑料容器、尤其是用于机动车的塑料容器。
背景技术
通常至少在可视区域内给用于机动车的容器喷漆,该容器具有至少一个朝外可视见的面。这种容器例如可以是用于摩托车的燃料箱。
为了实现高质量的外观,这种容器由能容易涂漆的材料制成,例如由金属制成。但是,这种容器是昂贵的并且具有大的重量。
发明内容
因此,本发明的任务是,提供一种用于机动车的容器,该容器重量轻,能够成本有利地制造并且同时具有能容易涂漆的表面。
按照本发明,所述任务通过一种模块化构造的塑料容器来解决,该塑料容器包括至少两个塑料部段,这些塑料部段借助塑料焊接相互连接,其中,所述塑料部段中的至少一个塑料部段在其外侧上具有可涂漆的覆盖层或者由可涂漆的材料制成。
这种容器具有如下优点,即通过使用塑料部段可实现小的总重量并且制造成本总体上是低的。可行的是,仅位于可见区域中的塑料部段设有可涂漆的覆盖层或由可涂漆的材料制成。因此,对于顾客来说产生视觉上高质量的外观。尤其是,可利用覆盖层的特定优点。
此外,通过将塑料容器分成各个塑料部段,可实现以简单的方式对塑料容器的单个区域进行涂漆。例如,各个塑料部段可在焊接之前被涂漆。由此,可在涂漆时无需遮盖各个区域。
特别有利的是,当这些塑料部段构造成使得在塑料容器的已装配的状态下至少一个塑料部段几乎完全位于可视见区域内时,至少一个另外的塑料部段被完全遮盖。以这种方式可行的是,可视见区域设有特别高质量的表面,而这些塑料部段在所述遮盖区域中保持没有涂漆或覆盖层并且因此可以是特别成本有利的。
根据一种实施形式,可涂漆的覆盖层可以是金属板或金属箔。漆通常特别好地附着在金属材料上。此外,可以为金属板设有个性化的设计。例如,金属板可以被设有个性化的雕刻或涂漆。顾客可将其名字雕刻到金属板上或将家族徽章或协会标志涂漆到金属板上。这种个性化可以非常简单地通过事后在货商处装配金属板来实现。此外,通过金属板可改善塑料部段的稳定性。因此,塑料的经济上的优点可以与金属的光学和结构上的优点相结合。
金属板优选具有小的壁厚。这是可行的,因为金属板本身不必承担容器功能。因此,在制造金属板时能够实现高的拉伸率,能够实现高质量的设计形状。
例如,可涂漆的覆盖层由铝或钛制成。这些材料被认为是特别高质量的并且也可至少部分地保持没有涂漆。在一种特别成本有利的实施形式中,可涂漆的覆盖层可由钢板构成。
根据另一种实施形式,可涂漆的覆盖层可具有塑料或由塑料制成。例如,可涂漆的覆盖层是塑料成型件或塑料薄膜。该塑料部段在这种情况下可以由基体和覆盖层组成,其中,基体具有第一塑料组分并且覆盖层具有第二塑料组分,第二塑料组分在其组成方面与第一塑料组分不同。具有由塑料制成的覆盖层的容器与具有金属组分的容器相比可以具有特别小的重量。可涂漆的覆盖层优选用塑料背面注塑。由于增强件能以简单的方式集成到塑料成型件中,因此可实现各个塑料部段的特别高的稳定性并且因此实现整个容器的高稳定性。在背面注塑时,塑料可直接与覆盖层连接,而不需要附加的连接元件。尤其是,背面注塑的塑料能够附着在覆盖层上。
在另一种变型方案中,覆盖层可借助至少一个连接器件装配在塑料部段上。例如,覆盖层可被拧紧、铆接或粘接在塑料元件上。由此,覆盖层与塑料部段的连接特别可靠。使用可拆卸的连接器件、例如螺钉具有附加的优点,即在覆盖层损坏时覆盖层可简单且成本有利地被更换。
为了能够将覆盖层特别简单地装配在塑料元件上,覆盖层可具有至少一个装配元件。例如装配元件包括钩。装配元件可用于将覆盖层挂在或卡锁在一个塑料部段上。装配元件尤其是用于预装配覆盖层,例如其方式为在覆盖层借助连接元件与塑料部段固定连接之前,覆盖层借助装配元件被挂在塑料部段上。因此,通过所述至少一个装配元件可简化覆盖层的装配并且减少所需的连接器件的数量。
每个塑料部段可具有至少一个至少部分环绕的焊接凸缘。焊接凸缘用于借助塑料焊接连接塑料部段。
塑料容器可具有至少三个塑料部段,其中,至少一个塑料部段构造成两侧开放的中间部分并且至少两个另外的塑料部段构造成单侧开放的盖并且所述盖在两侧设置在所述中间部分上。这具有以下优点,即也可实现该塑料容器的复杂的几何结构,而不需要复杂的工具。
塑料容器例如可以尤其是用于摩托车的燃料箱。在摩托车中,燃料箱通常设置在导杆与座椅面之间的区域中并且具有朝外可视见的涂漆的面。通过本发明可将塑料的优点与金属或其它材料的光学特性相结合。
优选地,该塑料容器至少部分地被隔板遮盖。该隔板可具有保护的功能。例如,该隔板由金属制成并且也被涂漆。在燃料箱、例如用于摩托车的燃料箱的情况中,该隔板可保护燃料箱在撞击地面时免受损坏。尤其是由于石头或者其它尖锐的对象而存在损坏塑料容器的风险。通过使用隔板,该塑料容器可仅具有小的壁厚并且尽管如此仍可被保护免受损坏。此外,在维修时可保持低的修理成本,因为仅必须更换隔板并且不必更换整个塑料容器。
附图说明
本发明的其它的特征和优点由后续说明和后续参考的附图得出。在附图中:
图1示意性地示出按照本发明的塑料容器的部分剖面,
图2示意性地示出用于按照本发明的塑料容器的塑料部段,以及
图3a至3c示意性地示出用于制造按照本发明的塑料容器的可行方法的不同方法步骤。
具体实施方式
图1示出模块化的塑料容器10的部分剖面,该塑料容器10具有至少两个塑料部段12。该塑料容器10可以是燃料箱。
塑料部段例如成本有利地构造成注塑件。为了将塑料部段12相互连接,这些塑料部段例如可沿至少部分环绕的焊接凸缘14相互焊接,尤其是通过塑料焊接。
在所述两个塑料部段12中的一个塑料部段上设置有可涂漆的覆盖层16。所述可涂漆的覆盖层16可以是金属板、金属箔、塑料成型件、塑料薄膜或类似物。由此可行的是,塑料容器10成本有利地制造并且设有高质量的表面。在此,可涂漆的覆盖层16不必强制性地完全涂漆。也可仅对覆盖层16的一部分涂漆。例如,覆盖层16可包括特别高质量的材料,如铝或钛。此外可行的是,根据客户的个性化要求雕刻覆盖层16。
在所示的实施形式中,可涂漆的覆盖层被背面注塑。尤其是塑料部段12和可涂漆的覆盖层16相互连接。
附加于可涂漆的覆盖层16之外,在塑料容器10上设置有隔板18。隔板18也可以被涂漆,但是它主要具有保护功能。尤其是隔板18可具有高的强度。由此,塑料容器10的位于隔板18下方的塑料部段12可具有小的厚度并且因此节省材料地、成本有利地且容易地构造。在需要时,例如在塑料容器10碰撞时,隔板18保护位于其下方的塑料部段12免受损坏。同时隔板18简化维修,因为隔板18可容易被更换。
图2示出用于塑料容器10的塑料部段12,其中,与图1中所示的实施形式不同,可涂漆的覆盖层16不是背面注塑,而是覆盖层16借助连接器件20固定在塑料部段12上。连接器件在图2中仅示意性地示出。在此可以涉及螺钉、铆钉或类似物。替代地,可涂漆的覆盖层16也可粘接在塑料部段12上。
为了简化将可涂漆的覆盖层16装配在塑料部段12上,可涂漆的覆盖层16具有装配元件22、尤其是钩23。可涂漆的覆盖层16可借助钩23被预装配、尤其是挂在塑料部段12上。因此,连接器件20能以简单的方式被安装,而不必在装配期间由装配工将覆盖层16保持在其位置中。
图3a至图3c示意性地示出用于制造按照本发明的塑料容器10、尤其是制造塑料部段12的可行方法的各种方法步骤。所述方法的优点在于多个工作步骤的组合。但也可以常规地按顺序制造塑料部段12。
在图3a中示出的第一步骤中,将用于可涂漆的覆盖层16的材料放入到两件式的工具模型24中。
随后如图3b所示的,可涂漆的覆盖层16通过用高压喷射到型腔28中的塑料熔体26被挤压到型腔28中并且由此变形。替代地,可涂漆的覆盖层可在放入到工具模型24中之前或者在熔体26注入之前就已经例如通过深拉而变形。
在图3c中所示的进一步方法步骤中,塑料熔体26通过冲压冲头30压缩。随后,塑料部段12能够从工具模型24中被取出。可能突出的材料可以通过冲压被去除。
