Description

车用逃生锤 技术领域
本发明涉及安全逃生装置，特别是一种车用逃生锤。
背景技术
汽车、火车等交通工具当发生火灾、车祸、城市内涝等紧急情况下，使用逃生锤砸碎车窗玻璃是有效的自救手段。现在公共交通工具上都配备有砸玻璃的锤子，但是在使用时出现有的人不知如何使用，不知敲打玻璃何处才能将玻璃击碎的问题；而且需要很大的力气才能将玻璃击碎，对于老人小孩来说，能力有限没能顺利逃生；对于私家汽车没有配备这样的逃生工具，由车主自已购买后放在车上，可能会出现使用时找不着逃生锤的情况，难以满足遇险逃生的迫切需求。
发明内容
本发明的目的在于克服现有技术中的不足之处而提供使用简便，能准确、有效敲击到玻璃易碎部位，将车窗玻璃砸碎，成功逃生，而且不费力，大人小孩都会使用的车用逃生锤。
本发明的目的是通过以下途径来实现的。
车用逃生锤，包括弹性弹射构件和钢性碎玻球，碎玻球设置于弹
性弹射构件上，弹性弹射构件固定端固定于车窗一边框上，其它
边框上设置有一插口用于插接弹性弹射构件活动端上的插扣。
当钢性碎玻球被往外拉出，然后放开时，在弹性弹射构件的弹力作用下，产生冲击力将碎玻球击向玻璃。如同弹弓将钢球弹射出去， 击碎玻璃。当弹射出的钢球产生的冲击力(f)大于车窗玻璃承受的静载荷(p)时，钢球即可击碎玻璃。
本发明优选方案：弹性弹射构件固定端通过螺栓固定在边框上，
固定端和插口分别设置于璃车窗相邻的边框上，弹性弹射构件斜
拉于玻璃车窗四角处。
由于车窗玻璃四角面积较小，对力的扩散面积小，更容易被击碎。所以逃生锤砸在四角的位置比砸中心更容易将车窗玻璃砸碎。因此，逃生锤斜拉安装在靠近车窗玻璃四角处。
这样，弹性弹射构件固定端固定在边框上，在平时不使用时，活动端不固定，碎玻球处于自由放置状态，为了防止碎玻球左右摆动，可在弹性弹射构件活动端插扣的位置设置一绑带，固定碎玻球；另一边框设置有一插口，当遇到突发情况，需要破窗时，直接将插扣从绑带中抽出，插入插口中扣住。弹性弹射构件处于被拉伸状态，调整碎玻球位置于玻璃易碎位置。能有效地击碎玻璃。
本发明可进一步优化为：所述的弹性弹射构件固定端固定在距离
玻璃窗下边框120毫米高度的相邻边框上，插口固定在下边框120
毫米处，钢性碎玻球设置于弹性弹射构件中点。
这样，当插扣插入插口后，弹性弹射构件被拉伸，碎玻球位于弹性弹射构件中点位置，其中心至两边框的垂直距离为50毫米，处于玻璃最易碎位置，一插即就完成定位，十份快捷，为逃生赢得时间。
所述的弹性弹射构件为弹性皮筋，钢性碎玻球中心穿孔穿过弹性 皮筋，钢性碎玻球为直径5毫米以上钢球，或者12毫米以上钢球，或者18毫米以上钢球，分别配置于3毫米、5毫米和7毫米厚度的车窗玻璃上使用。
汽车车窗玻璃厚度(h)通常为3至7毫米，大小合适的钢球经弹性皮筋弹射出的冲击力(f)大于车窗玻璃承受的静载荷(p)时能击碎玻璃。
即：f>p
f＝mv1/t，p＝90·h·2r(其中，m为钢球质量，v1为钢球穿过玻璃前的速度，t为钢球和玻璃作用的时间，90MP为钢化玻璃表面应力，h为玻璃厚度，r为钢球半径)
t＝h/v(其中，v为钢球穿过玻璃的速度)
m＝4/3πr3·ρ(其中，ρ为钢球密度)
4/3πr3·ρ·v1·v>90h2·2r
皮筋打出的钢球的速度(v)一般为60—90m/s,现取60m/s，
所以假设钢球穿过玻璃前的速度V1为60m/s，穿过玻璃后速度V2为10m/s，则，平均速度为35m/s，钢球穿过玻璃的速度V为40m/s，
则；
1、当玻璃厚度h为3毫米，
r2>90×0.0032×2/(4/3×3.14×7.852×60×40)，
r>1.41毫米，
对于实心钢球直径大于3毫米。
此时，钢球冲击力f＝mv1/t＝4/3*3.14*0.00153*7.852*60*40/0.003＝88.6 公斤，3毫米玻璃的静载荷p＝90·h·2r＝90*3*2*0.0015＝81公斤，冲击力大于玻璃静载荷，可以将玻璃击碎。
由于钢球中心需要穿孔用于弹性皮筋从中穿过，所以考虑加1.5倍的安全系数，钢球直径应为大于5毫米。
所以，碎玻球直径为5毫米以上钢球，可击碎3毫米车窗玻璃。
2、当玻璃厚度h为5毫米，
r2>90×0.0052×2/(4/3×3.14×7.852×60×40)，
r>4mm，
此时，钢球冲击力f＝mv1/t＝4/3*3.14*0.0043*7.852*60*40/0.005＝1009公斤，5毫米玻璃的静载荷p＝90·h·2r＝90*5*2*4＝360公斤，冲击力大于玻璃静载荷，可以将玻璃击碎。
由于钢球中心穿孔用于弹性皮筋从中穿过，所以考虑加1.5倍的安全系数，钢球直径应为大于12毫米。
所以，碎玻球直径为12毫米以上钢球，可击碎5毫米车窗玻璃。
3、当玻璃厚度h为7毫米，
r2>90×0.0072×2/(4/3×3.14×7.852×60×40)，
r>6毫米，
此时，钢球冲击力f＝mv1/t＝4/3*3.14*0.0063*7.852*60*40/0.007＝2434公斤，7毫米玻璃的静载荷p＝90·h·2r＝90*7*2*6＝756公斤，冲击力大超出玻璃静载荷，用很小的力就可以将玻璃击碎。
由于钢球中心穿孔用于弹性皮筋从中穿过，所以考虑加1.5倍的安全系数，钢球直径应为大于18毫米。
所以，碎玻球直径为18毫米以上钢球，可击碎7毫米车窗玻璃。
对于大小不同的钢球采用粗细不同的弹性皮筋以获得更强的冲击力。
所述的的弹性弹射构件还可以为弹簧条，钢性碎玻球固定于弹簧条中点。
本发明还可进一步优化为：钢性碎玻球的表面具有尖形突起。
这样，大大增强了破坏力，车窗玻璃更容易被砸碎。
综上所述，本发明比现有技术具有如下优点：结构简单，使用快捷，定位准确，用很小的力气就能将车窗玻璃击碎，达到事半功倍的效果。老人小孩都能使用，满足逃生迫切的需求。
