Description

爆胎应急支撑装置 技术领域
本公开一般涉及汽车领域的安全装置，尤其涉及一种爆胎应急支撑装置。
背景技术
车辆在爆胎后，轮胎受到拖拽会迅速脱离轮辋卷入轮槽，轮胎与轮辋发生分离。金属轮辋在失压后因丧失支撑力而下沉直接与路面接触，这时车轮摩擦系数降低，丧失依靠轮胎向地面传递驱动力、牵引力、转向力及制动力等功能，从而导致车辆"雪崩"式失控，产生严重的侧滑、翻车事故。
而爆胎安全装置是一种安装在轮胎内部轮辋上的支撑装置。其可以在车辆爆胎后能有效支撑轮毂不与地面发生接触，依托瘪胎继续行驶一定距离，从而保持车辆安全。现有的爆胎安全装置，通常由一个环体组成，环体至少具有一个断开的端点，该端点通过紧固装置连接，从而通过紧固装置将环体设置于轮辋的外侧，并通过紧固装置调节环体的外径以抱紧轮辋，以达到紧固环体的目的。
但是，在紧固过程中，环体与轮辋会发生位移和摩擦，在紧固端点附件环体能够贴合轮辋，但是在较远侧难以紧固贴合。车轮在运行震动的情况下，环体容易发生松动、异响，对整车性能造成影响；并且在爆胎时轮胎瘪陷，松动的环体会随瘪陷的轮胎旋转而失效。

具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。其中，以图1中的右侧为前方，左侧为后方，垂直纸面向内的方向为内侧，垂直纸面向外的方向为外侧来进行描述。
图1示出了本发明第一实施例提供的爆胎应急支撑装置的结构示意图。如图1所示，爆胎应急支撑装置包括：支撑环1，支撑环1卡箍在轮辋的环状外表面上，以在爆胎时作为轮辋上的支撑装置，托起瘪胎、支撑轮辋。
其中，爆胎应急支撑装置还包括设置在支撑环1上的多个支撑件 2，支撑件2在支撑环1的内环面的伸出量可调节，通过调节支撑件2的伸出量以将支撑件2抵靠轮辋的轮槽底部。实质上，支撑件2用于将支撑环松动的部位紧绷，以实现支撑环与轮辋的环状外表面的紧固贴合；更为具体的，也即通过支撑件实现支撑环与轮槽(或轮槽边缘)的紧固贴合。
进一步地，多个支撑件2均匀分布在支撑环1上，通过多点设置的支撑件2调节支撑环1的内径，以通过均匀细微的调节使得支撑环1紧固并贴合轮辋的轮槽，这样的设置能够更普适于不同规格的轮毂。当然，对于特定规格的轮毂或者尺寸一致(包括尺寸具有细小差别的)的轮毂，由于支撑环上至少具有一个断开的端点，端点处通过紧固装置连接，远离端点处贴合不牢固，为了紧固支撑环，也可以优选在远离端点的部位设置多个支撑件，以针对贴合不牢固的位置进行紧固。
作为一种有利的实施方式，支撑件2可优选为旋转限位件，其与支撑环上设置的螺纹孔相配合以在支撑环的径向方向上旋进旋出，抵靠轮辋的轮槽底部。
如图2所示的本发明第一实施例提供的支撑件的结构示意图。支撑件进一步优选为螺丝20，支撑环上设置有螺纹孔(未示出)接收螺丝在其内旋进旋出。当然，旋转限位件的设置不局限于此，通过旋钮配合旋杆(旋转轴)的形式，在支撑环的径向方向上旋进旋出实现支撑件抵靠轮辋的轮槽底部均可。
作为一种有利的实施方式，支撑件2可优选为滑块定位件21，其包括高度调节块、带动高度调节块移动的滑块21a以及设置在支撑环上的导槽21b，滑块21a设置在导槽21b内；当移动滑块21a时，高度调节块伸出支撑环1的内环面并抵靠轮辋的轮槽底部。
可选的，如图3-图5所示的本发明第二实施例提供的支撑件的结构示意图，高度调节块优选为凸轮21c，凸轮21c的转轴与滑块相连。当拨动滑块21a时，凸轮21c随滑块的移动进行转动，凸轮21c在支撑环1的内环面的伸出量相应的改变，从而凸轮21c抵靠轮辋的轮槽底部，以实现支撑环个别松动点的紧固。当滑块21a在第一位置21e时,凸轮21c位于支撑环1的内环面的内侧；当滑块21a在第二位置21f 时,凸轮21c以最大伸出量伸出支撑环1的内环面。
可选的，高度调节块还可以优选为斜楔块，其与滑块相连接。在移动滑块时，可实现斜楔块在支撑环的内环面的伸出量。
进一步地，支撑环还可以为支撑垫带以及悬置于支撑垫带的径向内表面的多个抵脚，支撑垫带安装于轮辋的环状外表面，抵脚抵靠轮辋的轮槽底部。
上述实施例提供的在支撑环上安装有支撑件的爆胎应急支撑装置，在支撑环的径向方向上实现上对支撑环的个别松动点进行紧固调节以在爆胎的情况下提高支撑环的使用性能，结构紧凑，并且生产成本低。
为便于支撑环适配多种规格的轮毂，如图6所示的本发明第三实施例提供的爆胎应急支撑装置的结构示意图。如图7所示的第三实施例提供的枕块与支撑环连接的结构示意图。图8是本发明的爆胎应急支撑装置的第一种支撑环结构的示意图。图9是本发明的爆胎应急支撑装置的第二种支撑环结构的示意图。
参照图6至图9，支撑环1的内环面上分布有多个凹槽3，凹槽3的设置也使得支撑环1的弧度固定在一定范围内可以微调，以适应轮毂。
如图6和图7所示的第三实施例提供的爆胎应急支撑装置，区别于图1和图2结合所示的爆胎应急支撑装置，螺纹孔对应设置在凹槽3所在的部位；还包括：多个枕块4，每个枕块4的后部设有定位脚5，定位脚5与支撑环可拆卸连接。
进一步地，定位脚5能够被接收并可拆卸连接于相应的凹槽3内；并且定位脚5上设有通孔5’以与螺纹孔相匹配以接收旋转限位件。定位脚5插设在凹槽3中，装配简单，便于操作，可以对支撑环形成结构补强作用，以提高结构可靠性。
参考图6和图7，定位脚5沿轮毂的轴向方向插设在相应的凹槽3内,定位脚5沿轮毂轴向方向插入便于装配；并且
定位脚5沿轮毂的轴向方向在凹槽内的插入深度是可调节的。由于定位脚5与凹槽3沿轮毂的轴向方向可调节连接，通过定位脚5可 以适当沿轮毂的轴向方向调整枕块4，以使得适应不同宽度的轮槽6。从而使得本发明的爆胎安全装置能够适应不同宽度的轮辋，进而提高了爆胎安全装置的通用性。这样，与现有技术相比，不再需要开发多种型号规格产品以及其所对应的模具，降低了生产和制造的成本。
进一步地，在沿轮毂的轴向方向上，凹槽3的顶壁和定位脚5中的一者至少设有一个凸起部7，另一个至少设有一个凹陷部8，每个凸起部7和每个凹陷部8一一对应；凹槽和定位插脚通过凸起部与凹陷部之间的卡接而连接。可以在凹槽3的顶壁设置多个凸起部7，而在枕块4上设置与凸起部7对应的多个凹陷部8，也可以在凹槽3的顶壁设置多个凹陷部8，而在枕块4上设置多个凸起部7，通过凸起部7与凹陷部8之间的卡接，使得凹槽3和定位脚5，以实现枕块4沿轮毂的轴向方向上的多档位调节。每个凹陷部设置有一个通孔5’，用以方便螺丝旋入，螺丝通过通孔抵靠轮槽底部。
进一步地，支撑环1与定位脚5之间通过径向设置的紧固件紧固。当枕块4完成调整后，定位脚5与支撑环1通过凸起部7与凹陷部8卡接；此时，可以通过紧固件9依次穿过支撑环1和定位脚5，从而将支撑环1与定位脚5牢靠固定，提高了整体的结构可靠性。此处的紧固件9可以是螺栓紧固件9，但并不仅仅限于此，现有技术中可以起到紧固作用的紧固件9均可以应用于此。
进一步地，支撑环1的前端面在位于每个凹槽2的两侧位置处均设有定位孔10，枕块4与定位孔10对应的位置处设有定位柱11，定位柱11与定位孔10插接。通过11与定位孔10之间的插接配合，可以对定位脚5向凹槽3的插入起到导向作用，从而使得定位脚5能够准确并且稳定的插入到凹槽3内，进而提高了枕块的装配效率，也提高了装配的可靠性。
参照图8，在上述一个或多个实施方式中，支撑环包括呈半圆形的第一环体14和第二环体，第一环体和第二环体的两端部相互可拆卸连接。由于支撑环1多为刚性较强的材料制成，这样，半圆形状的第一环体14和第二环体，更便于支撑环1弯曲成不同弧度，再通过第一环体14和第二环体相互连接而形成整体的支撑环1，以便贴合轮槽弧 度，从而提高了支撑环1与轮槽之间配合的可靠性。
更为优选的实施方式，如图1和图9所示，所述支撑环1由多个支撑块15构成，每个相邻的所述支撑块15之间活动连接，所述凹槽3设置在所述支撑块15上，且支撑件2设置在凹槽3上。通过多个支撑块15之间活动连接而构成整体的支撑环1，更便于支撑环1弯曲成不同弧度，以贴合轮槽弧度，从而提高了支撑环1与轮槽之间配合的可靠性。
支撑环1包括呈半圆形的第一环体和第二环体，第一环体和第二环体均由多个支撑块15构成，第一环体和第二环体的两端部相互可拆卸连接。半圆形状的第一环体和第二环体，更便于支撑环1弯曲成不同弧度，再通过第一环体和第二环体相互连接而形成整体的支撑环1，以贴合轮槽弧度，从而提高了支撑环1与轮槽之间配合的可靠性。
进一步地，支撑环1的外环面设置有保护环16，用来保护支撑环，以延长支撑环的使用寿命。同样的，当支撑垫带加抵脚卡箍于轮辋的环状外表面时，支撑垫带外可以设置保护环以保护支撑垫带和抵脚，以延长支撑垫带的使用寿命。
以上描述仅为本申请的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本申请中所涉及的发明范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离所述发明构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本申请中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
