Description
技术领域
本发明涉及一种房车结构,具体地说是一种房车车头防撞顶及制造方法。
背景技术
众所周知,房车兼具房与车两大功能,是一种可移动、具有居家必备的基本设施的车种,基于此用途需要使房车具有足够大的空间以获得最佳的舒适度,因此,为了增大空间,现有的房车通常都在车头的顶部设置有弧形的前突部分,然而,现有技术中,普通房车的车头顶部,通常是采用板材直接制成的,当遇到限高通行桥洞或限高杆等场合时,尤其是驾驶员发现限高障碍时已来不及刹车躲避,房车驾驶员C证开小车遇到晚上风雨天,主要精力集中在路面及行人,开大车前上方的限高障碍发现时,初次驾驶95%以上都会撞上限高物,造成事故,轻的车身损坏、天窗、卫星天线、太阳能电板损坏,重者车身散架、乘员被家居砸伤;此时为获得较大空间而增高的部分很容易顶撞到限高面,虽然现有的房车的前突部分具有弧度,可以起到一定的缓冲不至于使整个车厢受损破裂,但是由于其是采用板材直接成的,因此,车头顶依然避免不了损毁,由此增大了更换成本。
发明内容
本发明要解决的技术问题是提供一种韧性好、可变性能力强且使用性能优越的房车车头防撞顶结构及制造方法。
为了解决上述技术问题,本发明的房车车头防撞顶,包括设置在房车顶部且突出于车头前方的从前至后为抛物线状结构的车头顶本体,车头顶本体包括玻璃钢材料的壁板以及在壁板内侧设置的纵横的龙骨,每根龙骨均包括有龙骨芯以及包覆在龙骨芯外的FRP材料,龙骨与壁板进行固化形成一体。
所述龙骨芯由泡沫材料或轻质木材制成。
所述龙骨为半圆状结构,所述龙骨的上平面一侧复合在壁板的内侧表面上。
所述龙骨外具有沿圆周表面开设的切槽,所述切槽与龙骨的边缘具有间距。
一种房车车头防撞顶结构的制造方法,包括以下步骤:
A、利用模具将多层玻璃纤维布或碳纤维通过粘结剂粘贴复合形成玻璃钢的壁板基体,其厚度为1-3cm;
B、在壁板基体的内层部分没有干燥前,粘贴龙骨芯,各条龙骨芯的间距为20-30cm,各条龙骨芯的半径为4-6cm;
C、在龙骨芯上粘贴多层复合的FRP材料形成龙骨主体,最终使龙骨主体的直径在龙骨芯的基础上增加0.5-1.5cm。
D、将壁板基体与龙骨主体进行固化并在固化成型后,利用切割刀具对龙骨主体进行切槽,切槽的宽度为1-3mm,切槽的深度为1.5-2.5cm。
所述步骤A中,玻璃钢的壁板基体与车厢主体一体成型。
所述步骤B中,龙骨芯纵横交错布置。
本发明的优点在于:车头顶本体采用玻璃钢材料的壁板与纵横交错的龙骨制成,增强了整体强度,与此同时,将龙骨主体采用泡沫或轻质木材龙骨芯以及粘结在龙骨芯的多层FRP材料进行制作,大大增加了整体的韧性,使龙骨具有一定的缓冲作用,从而避免了碰撞后车头顶本体直接碎裂,尤其是龙骨外表面开设切槽,受挤压变形时龙骨上的切槽能够具有一定的余量,可变性能力强,不会与壁板脱落,进一步保证了整体的可靠性,提高了使用的优越性,另外,车头顶本体设置为抛物线状结构且与车厢部分设置为一体进一步增强了整体强度。
附图说明
图1为本发明房车车头防撞顶的安装结构示意图;
图2为本发明中壁板与纵横交错的龙骨进行复合的结构示意图;
图3为本发明中单条龙骨与壁板进行复合的立体结构示意图。
具体实施方式
下面结合附图和具体实施方式,对本发明的房车车头防撞顶结构及制造方法作进一步详细说明。
如图所示,本发明的房车车头防撞顶结构,包括设置在房车1顶部且突出于车头前方的从前至后为抛物线状结构的整体式车头顶本体2,车头顶本体2包括玻璃钢材料的壁板3以及在壁板内侧设置的纵横的龙骨4,每根龙骨4均包括有龙骨芯5以及包覆在龙骨芯外的FRP材料(纤维增强复合材料)6,龙骨芯5由泡沫材料或轻质木材制成,另外,龙骨芯也可以由除了泡沫材料或轻质木材之外的其它材料进行制作,例如钢材,本实施例不对其进行限制;龙骨4的截面形状为半圆状结构,龙骨4的上平面一侧复合在壁板的内侧表面上,龙骨4与壁板3进行固化形成一体,车头顶本体2的外形为从前至后由低到高,再到低的抛物线状的整体式腔体,如同一个气球腔体,利用FRP高分子材料腔体,具有高回弹高韧性的特征,当抛物线状的前受到挤压时,受力点变形,受力因为抛物状由小变大的缓冲,减少腔体变形破裂的程度,在腔体还没有断裂时,障碍物还是向上划过,因此,本发明的房车车头防撞顶在车头3.2米高度遇到2.8米的限高车头不破损,车身不散架,有效保护乘员安全。
进一步地,所说的龙骨4外具有沿圆周表面开设的切槽7,切槽7与龙骨4的边缘具有间距,也就是说切槽并没有切割至龙骨的边缘。
一种房车车头防撞顶结构的制造方法,包括以下步骤:
A、利用模具将多层玻璃纤维布或碳纤维通过粘结剂粘贴复合形成玻璃钢的壁板基体,其厚度为1-3cm,制造过程中,玻璃钢的壁板基体可以采用模具与车厢主体一体成型;
B、在壁板基体的内层部分没有干燥前,粘贴泡沫材料或轻质木材等材料制成的多条龙骨芯,各条龙骨芯纵横交错布置,各条龙骨芯的间距为20-30cm,各条龙骨芯的半径为4-6cm;
C、在龙骨芯上粘贴多层复合的FRP材料形成龙骨主体,最终使龙骨主体的直径在龙骨芯的基础上增加0.5-1.5cm。
D、将壁板基体与龙骨主体进行固化并在固化成型后,利用切割刀具对龙骨主体进行切槽,切槽的宽度为1-3mm,切槽的深度为1.5-2.5cm。
例如在车辆行驶过程中,车前部具有2.8米限高时,车身具有3.2米高度,当抛物线状的车头腔体(整体FRP)受到挤压时,一方面,受力点因抛物状的腔体,力量由小变大的缓冲,减少了腔体变形的破裂的程度(FRP的断裂随时间变化),另外一方面,FRP的顺滑性减少的变形的时间,再一方面,在腔体还没有断裂前,障碍物迅速向上滑过,车棚床腔体不破裂,车身不散架,有效保护乘员安全。
