Description

一种全电化汽车尾板 技术领域
本发明涉及汽车尾板技术领域，尤其涉及一种全电化汽车尾板。
背景技术
汽车尾板是安装在货车和各种运输车辆的一种以车载蓄电池为动力的起重装卸设备，尾板作为一种随车装卸工具可以极大的提高装卸的效率和便利性。然而，现有的汽车尾板均采用液压系统，不易维护、“跑”“冒”“滴”“漏”、低温冻油等问题，即不环保也不美观。
发明内容
本发明提供一种全电化汽车尾板，解决了目前市场上液压汽车尾板不易维护、“跑”“冒”“滴”“漏”、低温冻油等问题。
为达到上述目的，本发明采用的技术方案如下：
一种全电化汽车尾板的电作动系统需要两种电动缸，分别为升降电动缸和翻转电动缸，每种电动缸左右对称设置各一只，通过连接支耳与横梁支座和平板铰接孔连接；所述电作动系统对应设置控制系统，控制所述电动缸的同步升降和到位停止。
进一步，所述电动缸包括缸筒、推杆、丝杠副、减速器、电机和连接支耳等。通过对各部件强度、寿命进行详细的校核，选用可满足使用的部件，同时对各部件进行标准化设计，极大的降低了电动缸的成本，最终在性能方面提升的同时降低整个尾板的价格，提供了一种成本低且安全可靠的电动缸。
进一步，所述电动缸采用T型自锁丝杠，可实现升降平台的任意位置的可靠机械锁定。
进一步，所述电动缸缸筒上设置行程保护开关，控制尾板平台到位停止。
提供了一种全电汽车尾板控制方法，选用成本较低的直流电机，通过两组继电器控制双缸同步上升和降落；每组继电器相互锁定，避 免操作失误损坏设备；通过行程开关控制尾板到位停止；保留液压尾板的操作习惯，提供控制箱控制和手操盒控制两种方式。
本发明的实施例提供了一种全电化的汽车尾板，不但具有液压尾板经济、高效、快速、省力的特点，同时解决了液压尾板不易维护、“跑”“冒”“滴”“漏”、低温冻油等问题，更加安全、可靠，并且可适用于各种恶劣环境。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本发明实施例提供一种全电化汽车尾板的结构示意图；
图2为本发明实施例提供的一种翻转电动缸的结构示意图；
图3为本发明实施例提供的一种升降电动缸的结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清晰，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚的描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图1所示，一种全电化汽车尾板，包括2只翻转电动缸2和2只升降电动缸4，翻转电动缸由电机21直接提供动力，通过减速机22带动丝杠副旋转，电动缸缸筒24内壁有键槽，推杆与丝杠副螺母通过螺钉连接，推杆24上有导向键，导向键在键槽约束下做直线运动，丝杠螺母带动推杆24伸出，电动缸通过上关节轴承26与面板1连接，下关节轴承23与横梁3连接。
综上来说，本实施例在传统尾部的基础上采用电作动装置，形成一种全电化汽车尾板，通过对电动缸结构的优化，很大程度上降低了 电动缸的生产成本，电动缸具有高效、清洁、免维护的特点。因此，本实施例中全电化汽车尾板将电动缸应用于汽车尾板中，可以有效的解决液压尾板不易维护、“跑”“冒”“滴”“漏”、低温冻油等问题。
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。
尽管本文较多地使用了电动缸、尾板、横梁等术语，但并不排除使用其它术语的可能性。使用这些术语仅仅是为了更方便地描述和解释本发明的本质；把它们解释成任何一种附加的限制都是与本发明精神相违背的。
