Description

一种具有限位结构的手推车 技术领域
本发明涉及车辆装置，特别涉及以一种具有防滑限位结构的手推车。
背景技术
随着商业和公共服务业的发展，商场、超市、机场等公共场所开始广泛的使用手推车及行李车等移动设备，以方便使用者搬运行李及物品。现有的手推车及行李车上也会安装电子播放设备以便于使用者获取信息或者商家进行位置信息、导航信息、广告信息及其它相关信息的播放。但是，目前的车辆很难解决旅客推行中行李滑落、行李架误碰使用者的脚部等问题。另外行李架自身的强度不高，重量大，也不美观。因此，在使用上存在较多不便之处。
发明内容
鉴于现有技术中存在的问题，本发明提供一种具有限位结构的手推车，其特征在于，包括用于承载物品的带有车轮的底座；与所述底座固定连接的车架，所述车架具有供手持的把手；设置在所述底座上的位于车头一侧的用于限制承载物品运动的第一限位板；设置于所述底座上的位于车尾一侧的用于限制承载物品运动的第二限位件，所述第二限位件表现为端面基本呈三角形的斜坡形元件，所述斜坡形元件具有面朝所述第一限位板的斜面。
在本发明的一些实施方式中，所述斜面相对于所述底座的倾斜夹角为30-45度。将倾斜角度设置为30-45度可以有效的增加手推车用于承载物品的面积，而且能够防止紧急制动时物品向后滑落。
在本发明的一些实施方式中，所述斜坡形元件包括设置于所述斜面两侧的基本竖向的第一支撑板和第二支撑板，所述斜面、所述第一支撑板和所述第二支撑板围合形成收容空间。
在本发明的一些实施方式中，所述车架具有自所述底座的首端向上延伸的两条支撑梁，所述第一限位板设置在所述两条支撑梁之间，所述斜面具有与所述两个支撑梁位置和形状相应的两个豁口，以当多辆所述手推车前后叠 加时，后车的所述支撑梁能够容纳在前车的所述豁口中。
通过在手推车的尾部设置收容空间以及在手推车的第一限位板上开设与支撑梁形状相应的豁口，可以在前后两车叠加推行时，使后车的支撑梁进入前车的豁口中，并且后车车头的一部分可以进入前车的容纳空间中。这样设置前后两车可以结合的更紧凑，不易脱开。并且只有相同类型的手推车，才能够进行上述叠加，便于归类安置。
在本发明的一些实施方式中，所述斜坡形元件的靠近使用者腿部一侧的外沿设有缓冲件(例如，橡胶)，以避免使用者的腿部或脚部与斜坡形元件触碰而受到伤害。发明
在本发明的一些实施方式中，所述底座和所述斜面上设有多个防滑肋条。发明所述多个肋条可包括交错配置的多个防滑肋条。
在本发明的一些实施方式中，所述防滑肋条包括沿所述斜面宽度方向间隔地设置的横向的第一肋条和第二肋条、由所述第一肋条和所述第二肋条沿所述斜面长度方向分别纵向延伸出的第三肋条和第四肋条，所述第三肋条与所述第四肋条彼此偏置。所述的长度方向为手推车首端到尾端的方向。通过设置横向和纵向交错的肋条，有利于增大底座和斜面的强度以达到薄板承重的目的，即降低自身重量的同时增加强度。同时还可以增大底座和斜面与被承载物品之间的摩擦力以防止物品滑落的作用。
在本发明的一些实施方式中，所述多个防滑肋条上还可以覆设有防滑橡胶。
本发明提供的手推车的在车头与车尾处分别设置有限制物品滑动的第一限位板和斜坡形的第二限位件，以使被承载物品能够稳固的放置于底座之上。并且，第二限位件的斜面向着位于车头的第一限位板的方向设置，当紧急制动时，可以保持承载物品有一定的滑动空间，但又不会从底座上滑落。同时，具有斜面的第二限位件能够增大承载面积，即使被承载货物的长度超出底座，也可以倾斜地放置于第一限位板、第二限位件和底座形成的承载空间中，且能够防止被承载物品滑落。

图2为本发明一实施方式的手推车立体示意图；
图3为本发明一实施方式中的限位板结构示意图；
图4为本发明一实施方式的多辆头推车叠加后的示意图。
具体实施方式
如图1所示，本发明一实施方式提供了一种手推车，包括底座1、设置于底座1首端的第一限位板2(车架)、设置第一限位板2一端的把手3以及设置于底座1尾端的第二限位板4。第二限位板4呈斜坡形状。所述的底座1、车架2、把手3以及第二限位板4之间形成用于承载物品的承载空间。
参照图2和3，第二限位板4包括倾斜设置的主体41。主体41靠近底座1首端的一侧与底座1固定连接，靠近底座1尾端的一侧向上倾斜。主体41的倾斜角度为30～45度。第二限位板还包括竖向设置的第一支撑板42和第二支撑板43。第一支撑板42和第二支撑板43相对地设置在主体41的两侧。第一支撑板42和第二支撑板43大致呈三角形。第一支撑板42和第二支撑板43的上表面均与主体41的下表面固定连接。第一支撑板42和第二支撑板43的下表面与底座1固定连接。如此设置，主体41的前端与底座1固定连接，主体41的后端从底座1的尾端向上方倾斜地延伸出底座1的边缘。即主体41、第一支撑板42、第二支撑板43之间形成了一个不完全封闭的容纳空间。当然，在另外的实施方式中，主体41可以不延伸出底座1，而是整体都位于底座1上。在这种情况下，主体41、第一支撑板42、第二支撑板43以及底座1形成容纳空间。应当能够理解，以这种方式形成的容纳空间相对于上一实施方式形成的容纳空间较小。
，仍然参照图3，第二限位板的主体41的上表面具有多个肋条。具体地，包括相间隔地设置的第一水平肋条44和第二水平肋条45，由第一水平肋条44向着底座1的首端方向延伸出的多个第三竖直肋条46以及由第二水平肋条45向着第一水平肋条44的方向延伸出的多个第四竖直肋条47。第一水平肋条44与第二水平肋条45平行。多个第三竖直肋条46与第一水平肋条44相互垂直。多个第四竖直肋条47与第二水平肋条45相互垂直。第四竖直肋条47与第一水平肋条44具有连接点。因此，第一水平肋条44与第三竖直肋条46、第二水平肋条45与第四竖直肋条47组成大致为“EE”形的图案。第一 水平肋条44的长度大于第二水平肋条45的长度，并且第四竖直肋条47与第一水平肋条44的连接点大致位于相邻的两个第三竖直肋条46所截取的第一水平肋条44的中点处。第一水平肋条44、第二水平肋条45、第三竖直肋条46以及第四竖直肋条47上贴合有软质橡胶或者被软质橡胶从***包覆。
在本实施方式中，第二限位板还包括设置于主体41向上倾斜的末端的被软质橡胶包覆的限位块48，所述限位块48作为缓冲件。主体41上位于限位块48的两侧对称地设置两个豁口49。在设置了多个横向和纵向交错的肋条之后，本发明的第二限位板的强度得到了加强，并且当物品被承载于所述的底座1、第一限位板2、把手3以及第二限位板之间形成的承载空间时，第二限位板能够提供较大的摩擦力，以防止物品滑落。
如图2所示，本发明的第一限位板2包括两根设置于底座1首端的支撑梁21以及设置在两根支撑梁21之间并与所述支撑梁21固定连接的挡板22。支撑梁21的一端与底座1固定连接，另一端与把手3固定连接。挡板22仅与两根支撑梁22固定在一起，不与底座1连接。因此，挡板22与底座1之间具有空隙23。
底座1的首端设计成与第一支撑板42、第二支撑板43和主体41之间形成的容纳空间相同的形状，以便当这种手推车需要被叠加地推行或者放置时，后车的底座1的首端能够进入前车的容纳空间内。与此同时，第二限位板4的限位块48以及主体41的一部分穿过挡板22与底座1之间的空隙23，限位块48反向卡合在挡板22之上。后车的两根支撑梁21正好能够进入前车的第二限位板4的豁口49内。当前后两辆手推车需要分离时，需将后车略微抬起，以使限位块48从挡板22上脱离。
按照上述设置，第二限位板4不仅仅能够为承载于手推车上的物品提供摩擦力，而且在两车叠加时还起到了定位作用。第二限位板4上设置肋条以使其自身强度得到加强。另外，限位板4还包覆了软质橡胶，以避免其与被承载物品之间发生碰撞和摩擦，以使被承载物品发生损坏。当使用者推行该手推车时，使用者的脚部不小心触碰到第二限位板4尾部的限位块48或主体41，其不会产生剧烈震动而导致使用者受到伤害。进一步地，底座1上也可以设置一些防滑肋条(图未示)。
以上对本发明的各种实施例进行了详细说明。本领域技术人员将理解， 可在不偏离本发明范围(由所附的权利要求书限定)的情况下，对实施方案进行各种修改、改变和变化。对权利要求范围的解释应从整体解释且符合与说明一致的最宽范围，并不限于示例或详细说明中的实施范例。
