Description
技术领域
本发明涉及顶棚技术领域,具体涉及一种车辆顶棚和车辆。
背景技术
汽车顶棚是指汽车内部的一种必要结构构件,现有的汽车中,在整车进行整备时会在车身顶部安装顶棚,从而保证乘客、驾驶员乘坐的舒适性及安全性,并实现隔热、降噪的效果。近年来,随着消费水平的不断提高,消费者对汽车各项功能的要求不断提高,而顶棚作为车身内可视面积较大的功能件,其可集成多个元件。但集成的元件越多,顶棚越长。对于尺寸较长的顶棚,如何保证顶棚的强度,使得顶棚在搬运和安装的过程中不会发生折断或变形,成为亟需解决的难题。因此,需要提供一种车辆顶棚和车辆。
发明内容
鉴于以上现有技术的缺点,本发明的目的在于提供一种车辆顶棚和车辆,以改善现有技术中车辆顶棚中集成有多个功能件时,在搬运或安装过程中易折断的问题。
为实现上述目的及其它相关目的,本发明提供一种车辆顶棚,包括:顶棚本体和多个加强框;
上述顶棚本体上开设有多个功能件安装口;
上述多个加强框安装在所述顶棚本体上,且各所述加强框分别环绕对应的功能件安装口设置;
其中,各所述加强框的形状与对应的功能件安装口的形状相适配。
在本发明一实施例中,沿所述顶棚本体的边沿设置有多个弹性垫块。
在本发明一实施例中,多个所述弹性垫块分别对称粘接在所述顶棚本体的两侧边沿上。
在本发明一实施例中,多个所述弹性垫块的长度相同。
在本发明一实施例中,所述顶棚本体上还开设有吸顶屏安装口,所述吸顶屏安装口位于两个所述功能件安装口之间,所述吸顶屏安装口的两侧安装有加强桥梁。
在本发明一实施例中,所述吸顶屏安装口的中心轴线分别和相邻两个所述功能件安装口的中心轴线重合,所述加强桥梁沿所述吸顶屏安装口的中心轴线,分布在所述吸顶屏安装口的两侧。
在本发明一实施例中,所述加强框为铁质的加强框。
在本发明一实施例中,所述顶棚本体的结构包括:
第一无纺布层;
第一聚氨酯基材层,设置在所述第一无纺布层上;
第二聚氨酯基材层,设置在所述第一聚氨酯基材层背离所述第一无纺布层的一侧;
第二无纺布层,设置在所述第二聚氨酯基材层背离所述第一聚氨酯基材层的一侧;
面料层,设置在所述第二无纺布层背离所述第二聚氨酯基材层的一侧。
在本发明一实施例中,所述第一聚氨酯基材层包括依次层叠的玻璃纤维、粘着剂、聚氨酯泡片、粘着剂和玻璃纤维,所述第二聚氨酯基材层包括依次层叠的粘着剂、聚氨酯泡片、粘着剂和玻璃纤维。
在本发明一实施例中,还提供一种车辆,包括车身,所述车身的顶部安装有车顶钣金,其特征在于,所述车顶钣金朝向所述车辆内部的一侧上安装有上述任一项所述的车辆顶棚。
综上所述,本发明提供一种车辆顶棚,通过在顶棚本体上开设有多个功能件安装口,并在每个功能件安装口对应安装有形状适配的加强框,以加强功能件安装口周边的强度,防止顶棚在搬运、装配等过程中,由于顶棚本体上开设的功能件安装口过多,导致顶棚易出现弯折等变形情况。极大提升了顶棚的整体强度,使得顶棚在运输、包装、安装的全过程中都不易弯折损坏。本发明提供的车辆上,在车顶钣金上安装有本发明提供的车辆顶棚,提升了车辆整体的使用期限。

请参阅图1,图1显示为本发明一实施例中车内侧顶棚的结构示意图;本发明提供一种车辆顶棚和车辆,解决了长度较长的顶棚本体100,其上开设多个大小不一的功能件安装口时,在搬运过程中易发生弯折的情况。提升了顶棚的整体强度,使得顶棚在运输、包装、安装的全过程中都不易弯折损坏,提升了顶棚的使用期限。
请参阅图1和图2,图2显示为本发明一实施例中车外侧顶棚的结构示意图。车辆顶棚包括:顶棚本体100和多个加强框200。顶棚本体100为近似长方形结构,并在装配到车顶后具有一定弯曲弧度。顶棚本体100上开设有多个功能件安装口,通过在各功能件安装口安装对应的功能件(未在图中示出),以充分满足用户的各项需求。具体地,顶棚本体100上分别开设有前顶灯安装口240、前天窗安装口230、后天窗安装口210等功能件安装口,并在后天窗安装口210的两侧分别开设有对应的氛围灯安装口250,以集成安装氛围灯(未在图中示出)、阅读灯(未在图中示出)和出风口(未在图中示出)等组件。进一步地,为了为车内乘员提供更加舒适的环境,在前天窗安装口230和后天窗安装口210上分别安装有遮阳帘(未在图中示出),以有效遮挡阳光,并在后天窗安装口210的边沿处开设有扬声器安装口220和麦克风安装口260。多个加强框200安装在顶棚本体100上,且各加强框200分别环绕对应的功能件安装口设置,其中,各加强框200的形状与对应的功能件安装口的形状相适配。可在加强框200朝向顶棚本体100的一侧喷涂有热熔胶,并将加强框200冲压热熔到顶棚本体100朝向车顶钣金(未在图中示出)的一侧,通过这种强大的压力和粘合力,有效保障了加强框200在顶棚本体100上的牢固性,使得加强框200不易从顶棚本体100上脱离,极大提升了车辆的安全性。尤其对于长度较长的车辆顶棚,且开设的功能件安装口较多,在搬运和安装过程中,极易发生弯折。因此,通过在各功能件安装口布设加强框200,从而增强车辆顶棚整体的刚性,有效减少了顶棚弯折的情况发生。
可以理解的是,本发明所述的功能件包括但不限于前顶灯、前天窗及其遮阳帘、后天窗及其遮阳帘、氛围灯和扬声器,本领域技术人员可根据车辆的实际需求适应性加入或删减相应的功能件,在此不做限定。
请继续参阅图1和图2,在本发明一实施例中,所述加强框200为铁质的加强框200。相较于塑料材质,铁质的加强框200具有良好的刚性,且不易发生变形。在遇到极寒或极热等极端天气时,铁质的加强框200不会在此温度下发生热胀冷缩,以防止车辆顶棚由于加强框200的热胀冷缩,导致车辆顶棚朝向车内一侧的面料出现褶皱的情况。此外,通过在每个功能件安装口都设置铁质的加强框200,可在车辆顶棚储存过程中,通过加强框200将车辆顶棚悬挂到墙上,减少车辆顶棚的占地面积,同时加强框200可承受较大的悬挂力,避免车辆顶棚在悬挂过程中发生变形。通过在各功能件安装口均安装有铁质的加强框200,有效防止顶棚在包装、搬运和安装的全过程中发生断裂,提升了顶棚的刚性。进一步地,在本发明一实施例中,加强框200为加厚的加强框200。加强框200的厚度由原有的0.7mm加厚至0.8mm,通过加厚加强框200,可进一步提升加强框200的刚性,从而提升车辆顶棚的整体刚性,避免加强框200较薄时,在冲压生产过程中易发生变形的问题。
请参阅图1至图3,图3显示为本发明一实施例中车外侧另一角度顶棚的结构示意图。考虑到实际使用时,当他人位于车外,按压顶棚本体100的边沿时,易使得顶棚本体100发生凹陷变形(即从车内看,顶棚本体100在按压处向车顶的方向凹陷),进而导致凹陷处及其旁侧的密封条(未在图中示出)之间形成空隙。不仅极大降低了车辆的整体美观性,还会导致雨水或灰尘等异物,沿密封条和凹陷处之间形成的空隙,进入车内,在破坏车辆密封性的同时造成车内环境的污染。为了避免这一情况,在本发明一实施例中,沿所述顶棚本体100的边沿设置有多个弹性垫块400。弹性垫块400为长条形,多个弹性垫块400环绕排布在顶棚本体100朝向车顶钣金一侧的边沿处。需要说明的是,与现有车辆中的小弹性垫块相比,本申请所述的弹性垫块400具有较长的长度,在用户按压顶棚本体100的边沿时,按压处的弹性垫块400可起到缓冲作用,避免顶棚本体100在按压处出现凹陷变形。有效延长了顶棚本体100的使用期限,提升车辆整体美观性,有效阻挡灰尘、雨水等异物进入,为车内乘员创造干净的驾乘环境,提升了车辆整体的舒适性。
请继续参阅图1至图3,为了有效解决顶棚本体100边沿与密封胶条之间按压软的问题,弹性垫块400应具有一定硬度和回弹力。在本发明一实施例中,弹性垫块400的规格为20*20*360mm(即弹性垫块400的厚度、宽度和沿顶棚本体100边沿的长度分别为20mm、20mm、360mm),材料为聚乙烯。弹性垫块400的密度为45kg/m3。高于该密度的弹性垫块400,由于硬度较高,侧气帘(未在图中示出)点爆时,形成的弹性垫块碎块飞溅到车内,一旦砸到车内乘员,则会严重危害车内乘员的人身安全。低于该密度的弹性垫块400则由于硬度过软,无法对顶棚本体100起到有效的支撑和缓冲作用。可以理解的是,弹性垫块400的长度可根据顶棚本体100的长度适应性调整,在此不做限定。进一步需要说明的是,本申请所述的弹性垫块400的材质也可以为其他一切具有一定弹性和回缩力的材料,如聚氨酯等,在此不做限定。本申请所述的弹性垫块400,不过分追求高密度材质,因此成本较低,不仅可以在用户按压时,起到有效的支撑作用,保护顶棚本体100的边沿不会变形,还可以在侧气帘爆破时,不会伤及车内乘员,有效节约了企业的生产成本,利于量化生产。进一步地,为了节省生产工序,提升生产效率,在本发明一实施例中,多个所述弹性垫块400的长度相同。在实际生产时,可将加工后一整条弹性垫条,等距切割为多个长度相同的弹性垫块400,从而节约了企业生产成本,极大提升了生产效率。
请继续参阅图1至图3,在本发明一实施例中,多个所述弹性垫块400分别对称粘接在所述顶棚本体100的两侧边沿上。弹性垫块400的数量为偶数个,对称安装在顶棚本体100的两侧,并贴合在顶棚本体100前部和B柱之间的边沿、B柱和C柱之间的边沿、以及C柱和顶棚本体100尾部之间的边沿上。即弹性垫块400设置在顶棚本体100的边沿,并相对位于侧车窗(未在图中示出)的上侧,从而有效避免位于车辆外侧的用户通过侧车窗,向上按压顶棚本体100导致其凹陷变形的情况。进一步地,本发明另一实施例中,顶棚本体100的边沿在靠近B柱和C柱的位置处不设置弹性垫块400。这是由于顶棚本体100的边沿在靠近B柱和C柱的位置处形成具有一定弯度的弧面,因为弧面的弯折度较大,具有较好的强度,因此在受到外力作用时,该处顶棚本体100的边沿不易发生凹陷。为了节省弹性垫块400的资源,同时考虑到具有弯折形状的弹性垫块400难以生产,因此,仅在顶棚本体100较为平直的边沿粘接有弹性垫块400,即可起到有效支撑顶棚本体100的作用,防止顶棚本体100的边沿在外力按压下发生凹陷变形。
请继续参阅图1至图3,在本发明一实施例中,所述顶棚本体100上还开设有吸顶屏安装口300,所述吸顶屏安装口300位于两个所述功能件安装口之间,所述吸顶屏安装口300的两侧安装有加强桥梁500。在前天窗安装口230和后天窗安装口210之间,开设有吸顶屏安装口300,用于安装吸顶屏,以供用户观看各种视频节目。具体地,在本发明一实施例中,所述吸顶屏安装口300的中心轴线分别和相邻两个所述功能件安装口的中心轴线重合,所述加强桥梁500沿所述吸顶屏安装口300的中心轴线,分布在所述吸顶屏安装口300的两侧。由于前天窗安装口230、后天窗安装口210和吸顶屏安装口300均为矩形,且沿顶棚本体100的长度方向,前天窗安装口230的中心轴线、后天窗安装口210的中心轴线,以及吸顶屏安装口300的中心轴线,三者相互重合。因此为了加固吸顶屏安装口300,可沿中心轴线,将两个加强桥梁500分别对称贴合在吸顶屏安装口300的两侧,并使加强桥梁500位于吸顶屏安装口300朝向车顶钣金的一侧。其中,将吸顶屏装配到吸顶屏安装口300时,两侧的加强桥梁500可防止吸顶屏安装口300在外力作用下过分张开,导致装配过程中出现变形等问题,有效增强了顶棚本体100的刚性。
请参阅图1至图2,在本发明一实施例中,前天窗安装口230的两侧安装有固定支架700,固定支架700呈几字形,安装在前天窗安装口230朝向车顶钣金的一侧,并沿前天窗安装口230的中心轴线,对称分布在前天窗安装口230外边沿的两侧。其中,固定支架700朝向顶棚本体100的一侧通过热熔冲压的方式固定在顶棚本体100上,固定支架700背离顶棚本体100的一侧固定在车顶钣金上。从而在侧气帘点爆时,防止顶棚脱落。加强了车辆的安全性。进一步地,为了节约生产成本,固定支架700与对应的加强框200相互独立设置。由于固定支架700较小,可使用加强框200冲压后的剩余材料制作固定支架700,通过将前天窗安装口230上的加强框200,与其两侧的固定支架700相互独立设置,节省了冲压成本,降低了车辆的生产成本。此外,这种相互独立的设计,使得固定支架700或其对应的加强框200发生损毁时,仅更换相应的损毁件即可,不必整体更换,极大提升了配件更换的便利度。进一步地,为了提升整车的吸音隔音性能,在本发明一实施例中,在顶棚本体100未安装有功能件的裸露区域内铺设有吸音棉600,通过吸收外界的声音,达到降音作用。
请参阅图1至图4,图4显示为本发明一实施例中顶棚本体的材质结构示意图。由于本申请所述的车辆顶棚具有较长的长度(约为3086mm),属于超长顶棚,因此搬运过程中极易发生弯折,为了解决这一问题,在本发明一实施例中,所述顶棚本体100的结构包括:第一无纺布层110、第一聚氨酯基材层120、第二聚氨酯基材层130、第二无纺布层140和面料层150。其中,上述第一无纺布层110设置在顶棚本体100朝向车顶钣金的一侧。上述第一聚氨酯基材层120粘合在所述第一无纺布层110背离车辆钣金的一侧。上述第二聚氨酯基材层130设置在所述第一聚氨酯基材层120背离所述第一无纺布层110的一侧。上述第二无纺布层140粘合在所述第二聚氨酯基材层130背离所述第一聚氨酯基材层120的一侧。上述面料层150粘合在所述第二无纺布层140背离所述第二聚氨酯基材层130的一侧。对于集成多个功能件的超长顶棚,由于每个功能件都有一定的重量,单层的聚氨酯基材层无法承载过多的功能件,极易导致顶棚发生断裂。为了能承载更多的功能件,需使用双层的聚氨酯基材层。具体地,在本发明一实施例中,所述第一聚氨酯基材层120包括依次设置的玻璃纤维101、粘着剂102、聚氨酯泡片103、粘着剂102和玻璃纤维101,所述第二聚氨酯基材层130包括依次设置的粘着剂102、聚氨酯泡片103、粘着剂102和玻璃纤维101。在车辆行驶过程中,特别是颠簸路段,顶棚本体100的结构件之间会有抖动的现象,第一聚氨酯基材层120和第二聚氨酯基材层130形成的双层聚氨酯结构可保障结构件不会由于颠簸受损。在聚氨酯泡片的上下两层分别涂覆有粘着剂102,并将玻璃纤维101铺放在涂有粘着剂102的聚氨酯泡片103表面,众多细小的玻璃纤维101粘合在聚氨酯泡片103的表面上后,形成极薄的玻璃纤维毡,以使聚氨酯泡片103变硬。进一步地,为了减少生产成本,还可通过一般商业手段直接获取玻璃纤维毡,并将玻璃纤维毡通过粘着剂102粘附在聚氨酯泡片103的两侧。本领域技术人员可根据实际需要,选择适宜的方式制备第一聚氨酯基材层120和第二聚氨酯基材层130,在此不做要求。其中,粘着剂102可为一切具有黏着力的物品,例如胶水、胶浆等。需要说明的是,顶棚本体100也可包括三层或多层聚氨酯基材层,还可以为多层其他材料,本领域技术人员可根据实际需要适应性选择,在此不做限定。
需要进一步说明的是,由于玻璃纤维毡是使用粘着剂102将玻璃纤维101粘结而成,玻璃纤维101可选用长玻璃纤维或短玻璃纤维。当玻璃纤维毡由长度较短的短玻璃纤维制造而成时,由于制备时单位面积上交织的短玻璃纤维数量较多,因此该玻璃纤维毡的硬度较硬。相应的,当玻璃纤维毡由长度较长的长玻璃纤维制造而成时,由于制备时单位面积上交织的长玻璃纤维数量较少,因此该玻璃纤维毡的硬度较软。因此,长玻璃纤维和短玻璃纤维可影响制备的玻璃纤维毡的硬度,本领域技术人员可根据车辆的实际制造需求,适应性选择相应长度的玻璃纤维,在此不做限定。
请继续参阅图1至图4,考虑到聚氨酯泡片103较为蓬松,若只将第一聚氨酯基材层120和第二聚氨酯基材层130层叠到一起,会占用较大的车内空间,为了避免这一情况,在本发明一实施例中,将第二聚氨酯基材层130设置在所述第一聚氨酯基材层120背离所述第一无纺布层110的一侧后,还包括:对第一聚氨酯基材层120与第二聚氨酯基材层130进行压合处理。通过压合处理,可以进一步压缩聚氨酯泡片103的占据空间,最终使第一聚氨酯基材层120和第二聚氨酯基材层130的共同厚度,与传统的单层聚氨酯基材层的厚度近乎相同。一方面通过压合处理,达到压缩减容的效果,极大提升了车内的利用空间,为车内乘员提供更加舒适的乘坐环境。另一方面,相较于传统的单层聚氨酯泡片,压合后的聚氨酯泡片103密度增加,减弱了外界声音穿透到车内的力度,极大提升了车辆的NVH(Noise、Vibration、Harshness,噪声、振动和声学粗糙度)性能。进一步地,通过将第一聚氨酯基材层120和第二聚氨酯基材层130压合处理,形成双层聚氨酯结构,其在具有良好隔音效果的同时,还具有优秀的隔热作用,可有效阻隔外界热量进入车内,不仅提升了车辆顶棚的整体刚度,还有效提升了车辆的隔音及隔热性能。为车内乘员创造良好的驾乘环境,有效提升了驾乘人员的舒适度。
需要说明的是,本申请所述的车辆顶棚为一体式结构,即从车内乘员向车辆顶棚的方向看,没有任何拼接痕迹,这种设计方式一方面提高了车辆的整体美观性,另一方面使得顶棚更加牢固。
可以理解的是,为便于示例,本申请的第一无纺布层110和第二无纺布层140采用不同构图予以表示,但第一无纺布层110和第二无纺布层140的材质可以相同,也可以不同,在此不做限定。进一步需要说明的是,考虑到第一无纺布层110靠近车辆顶部,并与车顶的多个部件相邻接,在车辆启动或处于高温环境等状态下,车顶的部件温度较高,为避免胶水通过第一无纺布层110渗出,在本发明一实施例中,第一无纺布层110的密度大于第二无纺布层120的密度。由于第一无纺布层110常处于高温区域,通过提升第一无纺布层110的密度,从而使得整体布料更加紧密结实,一方面不易发生胶水外渗现象,另一方面高密度的第一无纺布层110不易在高温条件下发生变形,有效延长了使用期限。此外,考虑到第二无纺布层140的两侧分别为面料层150和第二聚氨酯基材层130,由于第二无纺布层140并不直接与车顶的部件相接触,而材料的密度越大,其重量越重,成本越高。综合衡量成本、顶棚的重量等各因素,因此本实施例中,第二无纺布层140的密度小于第一无纺布层130的密度。通过这种设计,不仅可有效避免第一无纺布层120在高温条件下易损坏的情况,延长了顶棚的使用期限,还能综合权衡生产成本、顶棚所需重量等因素,在尽量减少成本的同时,保证顶棚的刚度和强度不受影响。
可以理解的是,第一无纺布层120和第二无纺布层130也可采用相同材质、相同密度的材料制备,本领域技术人员可根据实际需要适应性选择适宜的材质或密度,在此不做限定。
需要说明的是,本申请所述的车辆顶棚采用无外漏安装方式,即从车内向车顶的方向看,顶棚为一个光滑的整体,没有任何裸露在外的螺栓等固定件,这种安装方式不仅极大提升了车辆的整体美观性,还可满足车辆的安全性,防止行驶过程中由于突发情况(如侧气帘点爆等)导致顶棚从车顶脱离。进一步需要说明的是,本申请所述的车辆顶棚,不仅适用于MPV(Multi-Purpose Vehicles,多用途汽车)这种超长的顶棚,还可适用于普通车辆顶棚,在此不做限定。
在本发明一实施例中,还提供一种车辆,包括车身,车身的顶部安装有车顶钣金,车顶钣金朝向车辆内部的一侧上安装有上述任一项实施例所述的车辆顶棚。其中,车辆还包括变速器(未在图中示出)、制动系统(未在图中示出)、转向控制系统(未在图中示出)、内饰组件(未在图中示出)、车辆地板(未在图中示出)和照明单元(未在图中示出)等。需要说明的是,对于车辆的其它构造例如变速器、制动系统、转向控制系统等均已为现有技术,且为本领域的技术人员所熟知,因此这里对于车辆的其它构造不做详细说明。
综上所述,本发明中,在顶棚本体上开设有多个功能件安装口,每个功能件安装口用于安装一种功能件,在各功能件安装口上,分别环绕安装有对应的加强框,从而加强顶棚的整体刚性。解决了长度较长的车辆顶棚,其上开设多个大小不一的功能件安装口时,在搬运过程中易发生弯折的情况。提升了顶棚的整体强度,使得顶棚在运输、包装、安装的全过程中都不易弯折损坏,提升了顶棚的使用期限。此外,通过使用双层聚氨酯层作为顶棚的基材,解决了集成复杂繁多的功能件时,具有双天窗的超长顶棚强度较弱的问题,进一步有效提升了顶棚的整体强度。进一步地,通过在顶棚本体的边沿设置弹性垫块,解决了顶棚与胶条区域按压软的问题,避免顶棚边沿在外力按压下出现塌陷。所以,本发明有效克服了现有技术中的一些实际问题从而有很高的利用价值和使用意义。
上述实施例仅例示性说明本发明的原理及其功效,而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下,对上述实施例进行修饰或改变。因此,举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所完成的一切等效修饰或改变,仍应由本发明的权利要求所涵盖。
