车厢分层装置的驱动器 技术领域
本发明属于物流运输设备技术领域，涉及一种车厢分层装置的驱动器。
背景技术
货物在车厢内运输的过程中，为了高效利用车厢内的空间，一般会在车厢内设置分层装置，从而实现货物的上下层放置，以避免空间的浪费。
现有车厢分层装置有支撑横梁式的，也有分层板式的。对于支撑横梁式的分层装置，其结构如中国专利文献公开的一种用于货箱内的分层装置(授权公告号：CN203020831U)，该分层装置通过在车厢内壁上沿竖向固连定位轨道，同时在平行相邻的两定位轨道之间设置支撑横梁，支撑横梁的两端均通过扣合件连接在定位轨道上且能沿定位轨道上下移动，扣合件与定位轨道之间具有使扣合件与定位轨道保持定位以防止定位支撑横梁下滑的扣合结构。在货物分层时，可以调节多根支撑横梁位于同一高度上，多根支撑横梁的下部可以放置一些货物，多根支撑横梁上部也形成了堆放货物的空间且多根支撑横梁一起对货物形成支撑，以此实现了车厢内货物的分层放置。现有支撑横梁式分层装置中，对于支撑横梁的上下位置调节都是通过手动的方式来调节的，由于支撑横梁为了保证具有较高的强度，一般质量都较重，因此手动调节的方式会导致操作的过程十分费力、浪费时间，而且，操作人员在车厢内操作，身旁都堆放着货物，不仅操作空间有限，操作麻烦，同时还存在安全性差的问题,现有技术中缺少专门用于对支撑横梁进行升降的驱动器。
对于分层板式的车厢分层装置，现有技术中存在利用驱动器，来实现分层装置自动升降的结构。如中国专利文献公开的一种自动传送分层车厢(授权公告号:CN205440076U)，该装置包括厢体、输送机构、绕绳盘、支撑装置、导杆和底板，输送机构和绕绳盘分别安装在厢体的内底上，厢体顶部分别安装有穿绳板和滑轮，支撑装置安装在厢体四壁上，导杆自上而下依次穿过穿绳板和底板与厢体内底连接，绕绳盘由电机一驱动，电机一连接调速器，绕绳盘的绳索通过滑轮和穿绳板与底板连接。通过电机一带动绕绳盘转动，绕绳盘的绳索通过滑轮和穿绳板提升底板，从而实现分层装置的自动升降。该装置中的分层装置驱动器包括电机一，该电机一为减速机和电机集成所形成的减速电机。该电机一的输出轴作为动力的输出源，通过在输出轴上连接绕绳盘，来实现底板的升降。这样的结构使得分层装置驱动器横向尺寸包含了减速电机壳体、输出轴、绕绳盘三者轴向的尺寸，导致该分层装置驱动器横向尺寸较大，占用了较大的车厢内部空间。
为了减小车厢分层装置的驱动器占用的车厢内部空间，减小驱动器的尺寸是一个较为直接的解决手段，现有技术中，通常都是通过以下几种方式来减小驱动器的尺寸：
1、减小驱动器的减速箱的尺寸：如采用尺寸较小的蜗轮蜗杆减速箱或行星减速箱，使驱动器整体尺寸减小。
蜗轮蜗杆减速箱中，蜗杆齿数往往可以很少，所以传动比可以很大，蜗轮蜗杆传动的传动比要比齿轮传动大得多，相同传动比的情况下，蜗轮蜗杆传动的所需体积也要比齿轮传动小得多，因此，蜗轮蜗杆减速箱具有尺寸小的特点。如中国专利文献公开的一种减速电机(申请号：201610659337.2)，该减速电机中在输出轴与电机的输入轴之间，采用蜗轮蜗杆进行减速传递，达到了结构紧凑、减速器尺寸更小的效果。
行星减速电机中，由于起减速作用的太阳轮、行星齿轮均位 于齿圈内，在一定程度上减少了减速箱轴的向尺寸。如中国专利文献公开的一种直流行星齿轮减速电机(申请号：201720045820.1)。
2、选择尺寸较小的电机，减小电机占用的空间。如盘式电机具有尺寸小的特点，是目前小型驱动器中，最常使用的电机。
3、改变减速箱中齿轮的材料，使得齿轮在保证强度的基础上，可以做得较薄，以此减小驱动器的尺寸。
4、提升装配精度，减小齿轮间的装配间隙，以此减小驱动器的尺寸。
发明内容
本发明的目的是针对现有的技术存在上述问题，提出了一种车厢分层装置的驱动器，本发明解决现有车厢分层装置的驱动器占用车厢内部空间大的问题。
本发明的目的可通过下列技术方案来实现：一种车厢分层装置的驱动器，包括安装座和固定设置在安装座上的驱动件，所述驱动件的转轴上连接有驱动齿轮，其特征在于，本驱动器还包括固定板和同步齿轮，所述固定板的其中一侧面用于与车厢内壁连接，所述驱动件和安装座均设置于固定板另一侧且安装座与固定板相固连，所述安装座与固定板之间设置有呈圆环形且可转动的同步带轮，同步带轮的内周面上沿周向设有内齿，所述同步齿轮与同步带轮的内齿相啮合，所述安装座、固定板以及同步带轮之间围合形成安装腔且驱动齿轮和同步齿轮均位于该安装腔内，所述驱动件的一端位于安装腔内且驱动件能带动同步齿轮转动。
本分层装置的驱动器主要用于车厢内支撑横梁的升降。在使用时，在每根定位轨道的上方分别固定本驱动器，同时，在每根定位轨道的下方设置从动带轮，然后在同步带轮与下方对应的从动带轮之间套设同步带能使同步带处于竖向设置，同步带的其中 一侧带体与支撑横梁的端部固连，这样当驱动件带动同步齿轮转动时，由于同步齿轮与同步带轮的内齿相啮合，因此能带动同步带转动，进而依靠同步带带动支撑横梁进行升降。
本驱动器固定板的其中一侧面用于与车厢内壁连接而驱动器设置于固定板另一侧，避免驱动件设置于固定板顶部或底部的情况下导致驱动器纵向尺寸增大的问题。由于支撑横梁的端部是在驱动器的下方移动的，因此驱动器纵向尺寸较小，这样支撑横梁向上收起不使用时，能使支撑横梁上升至更高而更靠近车厢的顶壁，以尽可能减小支撑横梁不使用时对车厢内部空间的占用，从而方便货物的装卸。而对于驱动器的横向尺寸，本案采用驱动件的一端位于安装腔内的设计，降低了驱动件的横向尺寸。同时，在安装座与固定板之间设置有可转动的同步带轮，采用同步带轮作为动力输出源，省去了如现有减速电机端部伸出的输出轴结构，避免了输出轴的设置带来的驱动器横向尺寸的增加，因此进一步减小了本驱动器的横向尺寸，从而方便在支撑横梁上放置货物。
在上述的车厢分层装置的驱动器中，所述安装腔内转动设置有与驱动齿轮相啮合大齿轮，所述大齿轮位于同步带轮朝向固定板的一侧，所述驱动件位于安装腔内的一端伸入同步带轮内。对于驱动件与同步带轮之间的传动结构，本驱动器采用了大齿轮相对同步带轮偏置的设计，即将大齿轮设置于同步带轮朝向固定板的一侧，而不是设置在同步带轮的内部，这样的设置使得大齿轮以及与大齿轮相啮合的驱动齿轮让出了同步带轮内部的空间，以供驱动件的一端伸入同步带轮内，从而最大程度地优化驱动器的横向尺寸，使得驱动器占用车厢内部空间小。
在上述的车厢分层装置的驱动器中，所述大齿轮和驱动齿轮均贴近于固定板的内壁设置，所述大齿轮同轴连接有与其同步转动的传动齿轮，所述传动齿轮与同步带轮相啮合。“贴近”是指大齿轮与驱动齿轮十分靠近固定板的内壁，与固定板内壁仅具有较 小的间隙，这样的设计既保证大齿轮和驱动齿轮能顺畅转动，而且结构更为紧凑，使得本驱动器能够做到整体横向尺寸仅仅略大于驱动件的横向尺寸，使驱动器占用车厢内部空间更小。
在上述的车厢分层装置的驱动器中，所述大齿轮的直径大于所述驱动齿轮以及所述同步齿轮的直径，所述同步齿轮的直径大于所述传动齿轮的直径。这样的设计在大齿轮与驱动齿轮之间形成一级减速，大齿轮与传动齿轮之间形成二级减速，传动齿轮与同步齿轮之间形成三级减速，即驱动件通过三级减速来带动同步带轮转动，使得驱动件在体积小、占用空间小的情况下，其输出扭矩能得到了保证。大齿轮与传动齿轮一体成型，两者轴心上开设有连接孔，固定板和安装板之间还固定设置有穿过连接孔的销轴，从而实现大齿轮与传动齿轮的安装。
在上述的车厢分层装置的驱动器中，所述安装座包括呈环形板状的安装板和固定插接在安装板内孔中的安装筒，所述驱动件固定设置在所述安装筒内，所述安装板与固定板相平行且间隔设置，所述同步带轮转动设置在安装板与固定板之间。作为优选，安装筒与安装板一体成型。通过设置安装筒来安装驱动件，保证驱动件安装稳定，安装板与固定板相平行且间隔设置，能够方便在两者之间安装同步带轮。
在上述的车厢分层装置的驱动器中，所述同步带轮的两个端面上分别沿周向开设有圆环形的第一滚珠槽，所述固定板的内壁上固连有呈圆环形的滚珠架，所述安装板的内壁和滚珠架上分别设有圆环形的第二滚珠槽，所述滚珠架和安装板上的第二滚珠槽分别与同步带轮两个端面上的第一滚珠槽一一对应设置，每个第一滚珠槽与对应的第二滚珠槽之间均设有若干滚珠且滚珠与第一滚珠槽和第二滚珠槽均形成贴靠。通过这样的设计，使得同步带轮周向上各个位置均受到了滚珠的支撑，避免同步带轮的窜动，进而避免由于同步带轮径向窜动导致同步带轮与同步齿轮之间齿 隙变化而出现咬齿的现象，保证同步带轮转动稳定，
在上述的车厢分层装置的驱动器中，所述第一滚珠槽包括与滚珠外壁贴靠的第一弧形壁和围绕同步带轮内孔边缘设置的平直壁，所述第一弧形壁位于平直壁的外周且与平直壁连接，所述第二滚珠槽包括与滚珠外壁贴靠的第二弧形壁，第二弧形壁靠近平直壁的边沿连接有朝向平直壁延伸的支撑壁，所述支撑壁与第一滚珠槽沿同步带轮的径向形成相对。所述平直壁的宽度方向沿同步带轮的径向设置。驱动器在带动支撑横梁上升的过程中，同步带轮会受到向下的作用力，因此需要保证同步带轮安装具有较好的稳定性。第一滚珠槽上的平直壁具有让位作用，使得第二弧形槽上的支撑壁能沿延伸至与第一滚珠槽形成相对的位置，支撑壁的设计能够在同步带轮的径向上对滚珠进行更好的支撑，以降低装配精度对滚珠稳定性的影响，同时在载荷增大、长时间使用等条件下，滚珠依旧能稳定地对同步带轮进行支撑，使得本驱动器稳定性好、载荷较大、使用寿命长。
在上述的车厢分层装置的驱动器中，所述大齿轮靠近滚珠架的边沿嵌入滚珠架与固定板的内壁之间。这样的设计保证大齿轮直径较大，进而增大减速比，使得驱动器在输出扭矩得以保证的前提下，能够减小电机的尺寸，进而使驱动器体积小。而通过固定板内壁设置滚珠架来安装滚珠，这样在进行组装时，可以依次将大齿轮和滚珠架安装至固定板上，使大齿轮安装方便，同时滚珠架的设计使得同步带轮周向上不同位置均受到滚珠的支撑，保证了同步带轮转动的稳定性。
在上述的车厢分层装置的驱动器中，所述驱动件为电机，所述固定板内壁的中部具有弧形板状的凸出部，所述凸出部具有供大齿轮的边沿嵌入的让位凹口，所述安装筒朝向固定板的端面与凸出部的端面抵靠，所述电机壳体的一端伸入凸出部内，所述凸出部的内周壁和安装筒的内周壁均与电机壳体的外壁形成匹配贴 靠，所述安装板上沿周向设置有若干连接销，所述连接销的两端分别与安装板和固定板固定连接。通过设置凸出部，利用凸出部的内孔、以及安装筒的内孔共同对电机进行支撑和固定，给电机提供了较大的安装面，保证了电机安装的稳定性。同时，凸出部还能供安装筒的端面进行抵靠，然后依靠连接销将固定板和安装板进行固连，这样能保证驱动器整体结构稳定。大齿轮直径较大时，能够增大减速比，使得驱动器在输出扭矩得以保证的前提下，能够减小电机的尺寸，进而使驱动器体积小。而凸出部设置供大齿轮的边沿嵌入的让位凹口，这样在通过凸出部保证电机安装稳定的基础上，还使得大齿轮能够贴近于固定板的内壁设置而不会与凸出部形成干涉，使得驱动器横向齿轮可以做小，而且，让位凹口进行让位后，大齿轮更为靠近固定板的中心位置，这样使得固定板的直径也可以做的较小，保证了驱动器具有较小的体积。
在上述的车厢分层装置的驱动器中，所述安装座上垂直连接有固定销，所述同步齿轮转动套设在固定销上，所述固定销的一端固连在安装座上且固定销的另一端仅与同步齿轮转动配合连接。本驱动器中同步带轮周向上各个位置均受到了滚珠的支撑，避免同步带轮的窜动，进而避免由于同步带轮径向窜动导致同步带轮与同步齿轮之间齿隙变化而出现咬齿的现象，同时同步齿轮无需承担来自同步带轮径向的压力，因此固定同步齿轮的固定销可以采用一端连接，一端悬空而仅与同步齿轮转动配合连接，这样的设计省去了在安装腔内额外设置支撑固定销的隔板结构，使得驱动器实现了节省材料和降低生产成本。
在上述的车厢分层装置的驱动器中，所述固定板呈圆形板状，所述的固定板外周壁上设有若干凸起部，每个凸起部上均设有螺栓过孔。螺栓过孔用于穿设锁定螺钉，在安装时，将驱动器放置于车厢内壁上，然后依靠锁定螺钉与车厢内壁进行连接，从而实现驱动器的固定。
与现有技术相比，本车厢分层装置的驱动器具有以下优点：
1、本车厢分层装置的驱动器用于带动车厢支撑横梁进行升降，可以在现有支撑横梁的基础上直接加装本驱动器，因此实用性强，适合广泛推广使用。
2、采用本车厢分层装置的驱动器，实现了支撑横梁的自动升降，具有自动化程度高，操作方便、安全性好的优点。
3、本分层装置的驱动器中，驱动件的一端插入同步带轮内，而且驱动器与同步带轮之间的减速传动机构也集成在安装腔内，这样的设计使得本驱动器具有较小的体积，集成度高，使得驱动器占用车厢内部空间小，方便货物的装卸。
4、驱动器在带动支撑横梁上升的过程中，同步带轮会受到向下的作用力，本驱动器采用同步带轮两端面上分别设有滚珠来支撑同步带轮，使得同步带轮能够承受较大的径向载荷，因此本驱动器具有载荷大、稳定性好的优点。如果采用多个齿轮沿同步带轮周向上间隔设置，且每个齿轮与同步带轮内齿相啮合的结构来支撑同步带轮，同步带轮受到的径向载荷较大时，会导致齿轮与同步带轮内齿出现咬齿的现象。

具体实施方式
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这一实施例。
如图1、图2所示，本车厢分层装置的驱动器包括安装座1、固定板4等部件，固定板4呈圆形板状，固定板4的其中一侧面用于与车厢23内壁连接，安装座1设置于固定板4另一侧且安装座1与固定板4相固连。安装座1包括呈环形板状的安装板1a和固定插接在安装板1a内孔中的安装筒1b，安装筒1b与安装板1a一体成型。安装板1a与固定板4相平行且间隔设置，安装板1a与固定板4之间设置有呈圆环形且可转动的同步带轮7。固定板4外周壁上设有若干凸起部42，每个凸起部42上均设有螺栓 过孔5。如图12所示，螺栓过孔5用于穿设锁定螺钉19，在安装时，将驱动器放置于车厢23内壁上，然后依靠锁定螺钉19与车厢23内壁进行连接，从而实现驱动器的固定。
如图3和图4所示，在安装座1的安装筒1b内固定设置有驱动件2，安装筒1b的设计保证驱动件2安装稳定，安装筒1b朝向固定板4的一端为敞口的设计，以方便驱动件2伸出，另一端封闭，以实现密封的目的。驱动件2优选为电机，电机的转轴两端均伸出电机的壳体，转轴的一端连接驱动齿轮3，转轴的另一端连接编码器，编码器图中未示出，编码器连接电缆线26且电缆线26从固定板4上的孔穿出，通过这样的设计以实现控制电机的调速、启停。
为了实现驱动件2带动同步带轮7转动，如图4、图5和图6所示，安装座1的安装板1a上垂直连接有固定销16，固定销16上转动套设有同步齿轮6。同步带轮7的内周面上沿周向设有内齿，同步带轮7的外周面上设有供同步带20套设的带齿，同步齿轮6与同步带轮7的内齿相啮合，安装座1、固定板4以及同步带轮7之间围合形成一个安装腔8且驱动齿轮3和同步齿轮6均位于该安装腔8内，驱动件2的一端位于安装腔8内且伸入同步带轮7内，安装腔8内转动设置有与驱动齿轮3相啮合大齿轮9，大齿轮9位于同步带轮7朝向固定板4的一侧。大齿轮9和驱动齿轮3均贴近于固定板4的内壁设置，大齿轮9同轴连接有与其同步转动的传动齿轮10，传动齿轮10与同步带轮7相啮合。大齿轮9与传动齿轮10一体成型，两者轴心上开设有连接孔，固定板4和安装板1a之间还固定设置有穿过连接孔的销轴18，从而实现大齿轮9与传动齿轮10的安装。大齿轮9的直径大于驱动齿轮3以及同步齿轮6的直径，同步齿轮6的直径大于传动齿轮10的直径。这样的设计在大齿轮9与驱动齿轮3之间形成一级减速，大齿轮9与传动齿轮10之间形成二级减速，传动齿轮10与同步 齿轮6之间形成三级减速，即驱动件2通过三级减速来带动同步带轮7转动，使得驱动件2在体积小、驱动器占用空间小的情况下，其输出扭矩能得到了保证。
如图5至图8所示，固定板4的内壁上设有呈圆环形的滚珠架12，所述滚珠架12上以及安装板1a内壁上均设有若干支撑同步带轮7使得同步带轮7能够转动的滚动件，若干滚动件沿同步带轮7的周向依次设置。作为优选，滚动件为滚珠14。具体地，同步带轮7的两个端面上分别沿周向开设有圆环形的第一滚珠槽11，滚珠架12通过销钉17固连在固定板4上，安装板1a的内壁和滚珠架12上分别设有圆环形的第二滚珠槽13，滚珠架12和安装板1a上的第二滚珠槽13分别与同步带轮7两个端面上的第一滚珠槽11一一对应设置，每个第一滚珠槽11与对应的第二滚珠槽13之间均设有若干滚珠14且滚珠14与第一滚珠槽11和第二滚珠槽13均形成贴靠。通过这样的设计，使得同步带轮7周向上各个位置均受到了滚珠14的支撑，避免同步带轮7的窜动，进而避免由于同步带轮7径向窜动导致同步带轮7与同步齿轮6之间齿隙变化而出现咬齿的现象，同时同步齿轮6无需承担来自同步带轮7径向的压力，因此固定同步齿轮6的固定销16可以采用一端连接，一端悬空的结构，如图4所示，固定销16的一端固连在安装座1上且固定销16的另一端仅与同步齿轮6转动配合连接，这样的设计省去了在安装腔8内额外设置支撑固定销16的隔板结构，使得驱动器实现了节省材料和降低生产成本。
进一步的，如图9和图10所示，图10中，为了能看清第一滚珠槽11和第二滚珠槽13的结构，隐藏了滚珠14。第一滚珠槽11和第二滚珠槽13内涂抹黄油，从而使滚珠14能顺畅的转动，同时，在滚珠架12与同步带轮7之间、以及安装板1a与同步带轮7之间分别设有密封圈27，从而起到防尘效果。第一滚珠槽11包括与滚珠14外壁贴靠的第一弧形壁111和围绕同步带轮7内孔 边缘设置的平直壁112，平直壁112的宽度方向沿同步带轮7的径向设置，第一弧形壁111位于平直壁112的外周且与平直壁112连接，第二滚珠槽13包括与滚珠14外壁贴靠的第二弧形壁131，第二弧形壁131靠近平直壁112的边沿连接有朝向平直壁112延伸的支撑壁132，支撑壁132与第一滚珠槽11沿同步带轮7的径向形成相对。驱动器在带动支撑横梁24上升的过程中，同步带轮7会受到向下的作用力，因此需要保证同步带轮7的安装具有较好的稳定性。第一滚珠槽11上的平直壁112具有让位作用，使得第二弧形槽上的支撑壁132能沿延伸至与第一滚珠槽11形成相对的位置，支撑壁132的设计能够在同步带轮7的径向上对滚珠14进行更好的支撑，以降低装配精度对滚珠14稳定性的影响，同时在载荷增大、长时间使用等条件下，滚珠14依旧能稳定地对同步带轮7进行支撑，使得本驱动器稳定性好、载荷较大、使用寿命长。
结合图4和图11，大齿轮9靠近滚珠架12的边沿嵌入滚珠架12与固定板4的内壁之间，这样的设计保证大齿轮9直径较大，进而增大减速比，使得驱动器在输出扭矩得以保证的前提下，能够减小电机的尺寸，进而使驱动器体积小。固定板4内壁的中部具有弧形板状的凸出部41，凸出部41具有供大齿轮9的边沿嵌入的让位凹口41a，安装筒1b朝向固定板4的端面与凸出部41的端面抵靠，电机壳体的一端伸入凸出部41内，凸出部41的内周壁和安装筒1b的内周壁均与电机壳体的外壁形成匹配贴靠，安装板1a上沿周向设置有若干连接销15，连接销15的两端分别与安装板1a和固定板4固定连接。通过设置凸出部41，利用凸出部41的内孔、以及安装筒1b的内孔共同对电机进行支撑和固定，给电机提供了较大的安装面，保证了电机安装的稳定性。同时，凸出部41还能供安装筒1b的端面进行抵靠，然后依靠连接销15将固定板4和安装板1a进行固连，这样能保证驱动器整体 结构稳定。大齿轮9直径较大时，能够增大减速比，使得驱动器在输出扭矩得以保证的前提下，能够减小电机的尺寸，进而使驱动器体积小。而凸出部41设置供大齿轮9的边沿嵌入的让位凹口41a，这样在通过凸出部41保证电机安装稳定的基础上，还使得大齿轮9能够贴近于固定板4的内壁设置而不会与凸出部41形成干涉，使得驱动器横向齿轮可以做小，而且，让位凹口41a进行让位后，大齿轮9更为靠近固定板4的中心位置，这样使得固定板4的直径也可以做的较小，保证了驱动器具有较小的体积。
下文结合图12并与背景技术中列举的现有技术进行比对，阐述本案驱动器结构如何实现节省车厢23内部的空间。
背景技术中列举的现有技术一种直流行星齿轮减速电机申请号：201720045820.1，该减速电机中：第一，电机整体位于箱体的外部，电机不占用行星架内部的空间，电机的转轴上连接太阳轮，太阳轮周向上设有与其相啮合的多个行星齿轮，太阳轮和行星齿轮形成的减速机构均位于行星架内；第二，行星架上连接输出轴，输出轴作为动力输出源，输出轴与电机的转轴同轴设置。该减速电机的设计其横向尺寸大于电机、太阳轮、动力输出轴三者相加的横向尺寸。
而本案的驱动器中，如图12所示，第一，本案的驱动器通过将大齿轮9和驱动齿轮3设置在同步带轮7朝向固定板4的一侧，在实现多级减速的基础上，让出了同步带轮7内部的空间，从而供驱动件2的一端伸入同步带轮7内，优化了驱动器的横向尺寸，使得驱动器占用车厢23内部空间小。第二，采用外周面带有带齿的同步带轮7来带动同步带20转动，同步带轮7作为动力输出源且套设在安装板1a和固定板4之间，省去了现有减速电机输出轴的结构，进一步减小驱动器的横向尺寸。
本案的驱动器中，驱动件2为电机，从图12中可以看出，电机的横向尺寸为h，驱动器整体横向尺寸为H，电机伸入同步带轮 7内后，电机的转轴几乎与固定板4贴靠，这样使得驱动器整体横向尺寸H仅略大于电机的横向尺寸h，显然，本分层装置的驱动器相比现有的行星减速电机，尺寸还进一步得到了减小，因此在安装至车厢23内壁上后，能大大减小车厢23内部的空间。而且，采用同步带轮7作为动力输出源，这样同步带20十分靠近车厢23的内壁，整套系统均能较少地占用车厢23的内部空间，不会影响货物的装卸。
下文简要介绍本车厢分层装置的驱动器的工作原理和使用方法：
图13和图14中，标号28的部件示意的是本车厢分层装置的驱动器。
如图13所示，车厢23左右两个内壁上均间隔设置有多根竖向设置的定位轨道25，且车厢23左内壁上的定位轨道25和右内壁上的定位轨道25一一相对设置，支撑横梁24的两端分别通过锁定结构连接在定位轨道25上，锁定结构处于锁定状态时，能对支撑横梁24进行固定，防止支撑横梁24向下移动。反之，锁定结构打开，能使支撑横梁24在定位轨道25上进行升降，调整支撑横梁24的高度。图13只是一个简单的示意，图中同步带20未示出、车厢23其中一侧内壁的轨道和驱动器也未示出。
在进行本驱动器的安装时，结合图12、图13和图14所示，在每根定位轨道25的上方分别固定本驱动器，驱动器应当是尽可能靠近车厢23顶壁进行安装，以尽可能减小占用的车厢23内部空间。同时，在每根定位轨道25的下方设置从动带轮22，从动带轮22与本驱动器的同步带轮7之间套设同步带20，同步带20具有上也具有带齿，从而实现与同步带轮7、从动带轮22进行稳定连接，防止打滑。支撑横梁24两端分别通过连接件21与对应的同步带20的其中一侧的带体固连，另外，从动带轮22优选采用张紧轮，这样能保证同步带20处于张紧的状态。在需要对车厢 23内的支撑横梁24进行升降时，支撑横梁24左右两端上方对应的两个驱动器的电机同步运转，电机依次经过驱动齿轮3、大齿轮9、传动齿轮10、同步齿轮6带动同步带轮7转动，同步带20转动时就能带动支撑横梁24进行升降，待支撑横梁24升降至合适的位置时，电机停止运转，完成支撑横梁24高度的调节。
