技术领域
本申请涉及叉车技术领域，特别涉及一种小体积运输车。
 背景技术
叉车是一种以货叉为取物装置，能将货物提升一定高度，可进行运输的车辆。目前，叉车出于车体配重的考量，通常将车体和货叉分置于门架的两侧，以使叉车的重心落在车体上，实现叉车的配重平衡。
但车体和货叉分置门架两侧的叉车布局会导致叉车整体体积过大，在仓储运输的过程中，需为叉车设计宽度更宽的巷道空间以供叉车行驶和转向。对于仓储运输而言，巷道空间增大会导致仓储容率降低，从而无法充分利用仓库的存储空间。
 技术问题
本申请的主要目的是提供一种小体积运输车，旨在通过减小叉车体积，提高仓储容率。

在本申请的一实施例中，所述承载轮设于所述支臂配重件远离所述车架的一端。
在本申请的一实施例中，所述小体积运输车还包括门架驱动件，所述门架驱动件设于所述车架配重件，所述门架驱动件的活动端与所述门架连接，以驱动所述门架靠近或远离所述车架；
所述门架的底部设有滚轮。
在本申请的一实施例中，所述安装腔朝向所述门架的一侧贯通至所述车架配重件的表面，所述门架驱动件背离所述门架的一侧插设于所述安装腔内壁。
在本申请的一实施例中，所述门架的两侧分别与两所述支臂滑动连接。
在本申请的一实施例中，所述支臂朝向所述门架的一侧设有滑槽，所述门架朝向所述支臂的一侧设有滑动件，所述滑动件可于所述滑槽中滑动。
在本申请的一实施例中，所述滑动件包括：

在本申请的一实施例中，所述小体积运输车还包括远程交互模组，用于远程控制所述小体积运输车运行。
 有益效果
本申请技术方案的小体积运输车包括车体、门架和货叉，其中，小体积运输车仅为减小叉车体积，但不对叉车的尺寸作出具体限定。车体包括可移动的车架，车架两端分别设有支臂，两支臂和车架围合形成用于收容门架和货叉的安装空间，门架可于安装空间内相对车架前后移动，带动货叉伸出安装空间叉取货物，或带动货叉缩回安装空间内以缩减小体积运输车运行时的整体体积。
在小体积运输车移动时，由于门架带动货叉缩回到安装空间内，车体两个支臂与货叉位于门架的同一侧，即车体与货叉位于门架的同一侧，相较于车体和货叉分置门架两侧的布局，本申请小体积运输车的布局可显著减小叉车的整体体积，从而可设置宽度较窄的巷道空间，提高仓库的仓储容率。

参照图1至图4，本申请提出一种小体积运输车100，包括：
车体10，所述车体10包括车架11，所述车架11可移动设置，所述车架11的两端分别连接有两支臂12，两所述支臂12相对设置，并与所述车架11围合形成有安装空间13；
门架20，所述门架20沿所述车体10的前后方向可移动地设于所述安装空间13，以靠近或远离所述车架11移动，所述门架20沿所述车体10的高度方向延伸设置；以及
货叉30，所述货叉30可升降地设于所述门架20，并位于所述门架20背离所述车架11的一侧。
本申请技术方案的小体积运输车100包括车体10、门架20和货叉30，其中，小体积运输车100仅为减小叉车体积，但不对叉车的尺寸作出具体限定。车体10包括可移动的车架11，车架11两端分别设有支臂12，两支臂12和车架11围合形成用于收容门架20和货叉30的安装空间13，门架20可于安装空间13内相对车架11前后移动，带动货叉30伸出安装空间13叉取货物，或带动货叉30缩回安装空间13内以缩减小体积运输车100运行时的整体体积。
在小体积运输车100移动时，由于门架20带动货叉30缩回到安装空间13内，车体10两个支臂12与货叉30位于门架20的同一侧，即车体10与货叉30位于门架20的同一侧，相较于车体10和货叉30分置门架20两侧的布局，本申请小体积运输车100的布局可显著减小小体积运输车100的整体体积，从而可设置宽度较窄的巷道空间，提高仓库的仓储容率。
门架20沿小体积运输车100的高度方向延伸设置，货叉30可升降地设于门架20，门架20还设有货叉驱动件（未标示），用于驱动货叉30升降，货叉驱动件可以是液压油缸、气缸或电机，在此不对货叉驱动件作出限定。
在小体积运输车100空载时，门架20和货叉30缩回至安装空间13内，小体积运输车100的仓储占用空间由车体10大小决定，相较于现有的小体积运输车100缩减了门架20和货叉30占用的仓储空间，空间占用率较小的小体积运输车100，可设计宽度更窄的巷道空间以供小体积运输车100行驶和转向，从而增加货物的存储空间，以提高仓储容率，降低仓储成本。
为了保证小体积运输车100配重平衡，在车体10内设有配重块以平衡货叉30和货物的重力，避免小体积运输车100向前倾覆。
在小体积运输车100取货时，货叉30下降到底，门架20于安装空间13内远离车架11前移，以带动货叉30伸出安装空间13叉取货物。货叉30叉住货物后，带动货物上升。当货叉30带动货物提升到一定高度时，门架20于安装空间13靠近车架11后移，以带动叉有货物的货叉30缩回安装空间13内，实现一次取货流程。
参照图1至图4，在本申请的一实施例中，所述车架11包括：
车架配重件111，所述车架配重件111的两端分别连接有两所述支臂12，所述车架配重件111内部形成有安装腔1111，所述车架配重件111的底部设有舵轮112；和
舵轮驱动件（未标示），所述舵轮驱动件设于所述安装腔1111内，所述舵轮驱动件的输出端穿设于所述车架配重件111，并与所述舵轮112传动连接，以驱动所述舵轮112转动。
在本申请一实施例的技术方案中，当支臂12和货叉30、车架11位于车架11同一侧时，为了平衡车体10的整体配重，避免小体积运输车100因货物重量过重而向前倾覆，车架11包括车架配重件111，车架配重件111内安装有若干配重块，配重块的材质可以是铸铁，也可以是混凝土，还可以是聚氯乙烯（PVC），在此不对配重块的材质作出限定。
车架11底部设有舵轮112，舵轮驱动件用于驱动舵轮112转动，以带动车架11移动。舵轮112的数量可以是一个，也可以是两个、三个或若干个，在此不对舵轮112数量作出限定。
配重块的总重量根据小体积运输车100设计要求进行定制，为了保证小体积运输车100整体的稳定性，通常将配重块固定于车架配重件111内部，在临时需要增加小体积运输车100配重以叉起超载的货物时，可将若干配重块装入安装腔1111内，以增加车架配重件111的整体重量，从而增加车架11的配重以叉起超载的货物。
当货叉30带动货物上升时，要确保整车重心落在车架11和门架20之间，从而避免小体积运输车100向门架20设有货叉30的一侧倾覆。小体积运输车100的配重块的总质量会根据载货重量上限和门架20提升高度进行综合优化，以避免小体积运输车100在取货过程中发生倾覆。车架配重件111的设置，提高了小体积运输车100运行时结构的稳定性。
参照图1至图4，在本申请的一实施例中，所述支臂12包括：
支臂配重件121，所述支臂配重件121的一端与所述车架配重件111的端部连接；
承载轮122，所述承载轮122设于所述支臂配重件121的底部。
在本申请一实施例的技术方案中，车架配重件111的两端连接有支臂配重件121，支臂配重件121用于平衡车体10左右两侧的重量，避免小体积运输车100叉有货物移动或转向时，小体积运输车100前后重量过大，导致两侧配重过轻，使小体积运输车100向左右两侧倾覆。
同时，在小体积运输车100叉取货物、货叉30上移的过程中，货叉30和支臂配重件121分别位于门架20的前后两侧，支臂配重件121可用于辅助车架配重件111进行配重，避免车架配重件111过重影响舵轮112使用寿命。
支臂配重件121底部的承载轮122可分担舵轮112所受的压力，延长了舵轮112的使用寿命。承载轮122的数量可以是一个，也可以是若干个，在此不对承载轮122的数量作出限定。
支臂配重件121内安装有若干配重块，配重块的材质可以是铸铁，也可以是混凝土，还可以是聚氯乙烯（PVC），在此不对配重块的材质作出限定。支臂配重件121的设置，可增加车体10整体质量及均布车身质量，提高了小体积运输车100运行时结构的稳定性。
参照图1至图4，在本申请的一实施例中，所述承载轮122设于所述支臂配重件121远离所述车架11的一端。
在本申请一实施例的技术方案中，承载轮122设于支臂配重件121远离车架11的一端，此时小体积运输车100的重心落在舵轮112和两个位于支臂配重件121端部的承载轮122联结形成的投影区域内。在货叉30叉起货物上升的过程中，通过支臂配重件121和车架配重件111内部配重块的设置，使叉有货物的小体积运输车100重心仍落在投影区域内，以避免小体积运输车100向前发生倾覆。当承载轮122设于支臂配重件121端部时，可提高小体积运输车100结构的稳定性。
为了进一步提高小体积运输车100结构的稳定性，当舵轮112的数量为一个时，可将舵轮112设于车架配重件111两端的中部，以与两个承载轮122形成稳定的支撑结构。
参照图1至图4，在本申请的一实施例中，所述小体积运输车100还包括门架驱动件40，所述门架驱动件40设于所述车架配重件111，所述门架驱动件40的活动端与所述门架20连接，以驱动所述门架20靠近或远离所述车架11；
所述门架20的底部设有滚轮21。
在本申请一实施例的技术方案中，门架驱动件40可以是液压油缸、气缸或电机，在此不对门架驱动件40作出限定。门架驱动件40可驱动门架20于安装空间13内移动，以靠近或远离车架11。从而带动货叉30伸出或缩回安装空间13中。门架驱动件40的设计，缩小了小体积运输车100的整体体积，提高了仓储容率。
门架20的底部设有滚轮21，滚轮21的数量可以是一个、两个或若干个，在此不对滚轮21的数量作出限定。滚轮21可分担舵轮112和承载轮122所受的压力，以延长舵轮112和承载轮122的使用寿命。
参照图1至图4，在本申请的一实施例中，所述安装腔1111朝向所述门架20的一侧贯通至所述车架配重件111的表面，所述门架驱动件40背离所述门架20的一侧插设于所述安装腔1111内壁。
在本申请一实施例的技术方案中，门架驱动件40背离门架20的一侧插设于安装腔1111的内壁，相较于直接设于车架配重件111的表面，可减小车体10的整体体积。安装腔1111朝向门架20的一侧敞口设置，使安装腔1111可容纳门架20的部分结构，以进一步减小车体10的整体体积，以提高仓储容率。
参照图1至图4，在本申请的一实施例中，所述门架20的两侧分别与两所述支臂12滑动连接。
在本申请一实施例的技术方案中，门架20的两侧分别与两支臂12滑动连接，以提高门架20结构的稳定性，支臂12起到了导向和辅助支撑的作用，可确保门架20只在安装空间13内前后移动，避免其在移动的过程中发生左右方向的侧动，导致货叉30定位不准确。同时，门架20与支臂12滑动连接，可优化门架20的载重上限，使门架20与车体10的配合更稳定，提高了小体积运输车100结构的稳定性。
参照图1至图4，在本申请的一实施例中，所述支臂12朝向所述门架20的一侧设有滑槽123，所述门架20朝向所述支臂12的一侧设有滑动件22，所述滑动件22可于所述滑槽123中滑动。
在本申请一实施例的技术方案中，滑动件22的一端设于门架20朝向支臂12的一侧，滑动件22的另一端插设于滑槽123中，并可以滑槽123中滑动。滑动件22的设计，可减小门架20与支臂12的摩擦阻力，使门架20的滑动更加顺畅，提高了小体积运输车100内部结构的稳定性。
参照图1至图4，在本申请的一实施例中，所述滑动件22包括：
托架221，所述托架221的一端与所述门架20连接，所述托架221背离所述门架20的一侧设有滑轮222，所述滑轮222插设于所述滑槽123；
所述滑轮222的周面与所述滑槽123的侧壁抵接。
在本申请一实施例的技术方案中，托架221的一端与门架20连接，托架221背离门架20的一端设有滑轮222，滑轮222插设于滑槽123中，并可于滑槽123中滑动。其中，滑轮222的周面与滑槽123的侧壁抵接，可避免门架20发生晃动，提高小体积运输车100运行时结构的稳定性。
门架20的两侧设有两托架221，为了进一步提高门架20移动时的稳定性，可将两托架221连接，使门架20与车体10之间的受力和配重更均匀，进一步提高小体积运输车100结构的稳定性。
在本申请的一实施例中，所述小体积运输车100还包括远程交互模组（未图示），用于远程控制所述小体积运输车100运行。
在本申请一实施例的技术方案中，远程交互模组的设置，使小体积运输车100可通过远程控制运行，实现小体积运输车100端的无人驾驶。无人驾驶的小体积运输车100，可省略现有小体积运输车100的人工舵柄设计，以遥控手柄取代人工舵柄，进一步缩小小体积运输车100的整体体积，减少空间占用，提高了仓储容率，使小体积运输车100适用于更窄的巷道。
同时，具有远程交互模组的小体积运输车100，可按照程序设定的行进路线进行取物，通过程序实现自动驾驶，降低了工作人员的劳动量，提高了运输效率。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
