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一简单地介绍， 显而易 见地， 下面描述中的附图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性的前提下， 还可以根据这些附图获得 其他的附图。

图 2C为本发明另一实施例中车辆卸货门连接处的结构放大示意图； 图 2D为本发明另一实施例中车辆卸货门连接处的结构放大示意图； 图 3A为本发明另一实施例中车辆卸货门连接处的结构放大示意图； 图 3B为本发明另一实施例中车辆卸货门连接处的结构放大示意图。 具体实施方式
为使本发明的目的、 技术方案和优点更加清楚， 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、完整地描述， 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作出创造性劳动前 提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明提供一种车辆卸货门， 图 2A为本发明实施例中车辆卸货门 的结构示意图， 图 2B为本发明实施例中车辆卸货门两个门板连接处的 结构放大示意图。 如图所示， 该车辆卸货门包括分别设置在两侧的第一 门轴 11和第二门轴 12，其中第一门轴 11上枢接有第一门板 13 , 第二门 轴 12上枢接有第二门板 14, 当该车辆卸货门关闭时， 所述第一门板 13 与所述第二门板 14对合；上述第一门板 13上，靠近第二门板 14一侧的 端部外侧固定设置有压缩弹性体 15 , 该压缩弹性体 15用于在所述车辆 卸货门关闭时密封所述第一门板 13和第二门板 14之间的缝隙 t， 具体 的是通过将压缩弹性体 15的长度设置为大于或者等于第一门板 13和第 二门板 14连接处的缝隙 t的长度， 以使车辆卸货门关闭时压缩弹性体 15能够密封所述第一门板 13和第二门板 14之间的缝隙 t。
本发明上述实施例中，通过在第一门板 13的端部外侧固定设置压缩 弹性体 15 , 使得在关闭两侧的门板时， 可以不再考虑第一门板 13和第 二门板 14的关闭顺序 ,而是直接关闭两侧的第一门板 13和第二门板 14， 此时压缩弹性体 15被压缩并密封所述第一门板 13和第二门板 14之间的 缝隙 t。 当装载散状货物时， 货物自身的重力使得第一门板 13和第二门 板 14变形， 导致缝隙 t变大， 但是由于压缩弹性体 15仍有一定的压缩 量， 仍能够起到密封作用。 因此， 本发明上述实施例提供的车辆卸货门 不需要设置复杂的控制两侧门板关闭顺序的控制装置， 因此结构简单且 仍能实现对车厢内散状货物的密封。
另外， 如图 2B所示， 上述实施例中的压缩弹性体 15可以是中空管 状的弹性体 , 弹性体的材料可以是橡胶或其他具有弹性的材料。
进一步地，根据本发明的另一实施例，为了提高压缩弹性体 15的使 用寿命，如图 2D可以在压缩弹性体 15的外侧包裹一层密封条 19，该密 封条 19可以由耐磨材料制成， 以提高压缩弹性体 15的耐磨性能。
具体地，为使得弹性压缩体 15密封第一门板 13与第二门板 14之间 的缝隙 t， 可以如图 2B和图 2C所示， 在第一门板 13的端部， 以及第二 门板 14的端部分别设置第一翻边 16和第二翻边 17，并将压缩弹性体 15 设置在第一门板的端部的第一翻边 16上， 这样在第一门板 13和第二门 板 14关闭时， 压缩弹性体 15被第一门板 13的第一翻边 16和第二门板 14的第二翻边 17压缩，起到密封第一门板 13和第二门板 14之间缝隙 t 的作用。
进一步， 据本发明的另一实施例， 如图 2C所示， 可以在第二门 板 14的端部的第二翻边 17上固定设置突出的密封条档 18,该密封条档 18设置在与压缩弹性体 15相对的位置上， 通过设置该突出的密封条档 18, 可以进一步的提高在第一门板 13和第二门板 14关闭时， 对压缩弹 性体 15的压力 ,以使得第一门板 13和第二门板 14之间的密封更加严密。 具体地，该密封条挡 18为具有一定厚度的条状材料，通过螺钉和螺母安 装在第二翻边 17的螺孔上， 当第一门板 13和第二门板 14闭合时， 密封 条挡 18抵靠在压缩弹性体 15上。通过更换不同厚度的密封条挡 18或者 在密封条挡 18与第二翻边 17之间增加或者减少垫片， 可以使得密封条 挡 18朝向压缩弹性体 15或者远离压缩弹性体 15运动，以调节压缩弹性 体 15的压缩量。 当然， 密封条挡 18还可以有其他的实现方式， 只要能 调节压缩弹性体 15的压缩量即可。
密封条档 18可以由非金属材料制成，比如橡胶、尼龙或树脂等材质， 以减少与压缩弹性体 15之间的摩擦， 延长压缩弹性体 15的使用寿命。 另外如图 2D所示， ^居本发明的另一实施例， 压缩弹性体 15的外侧包 裹有由耐磨材料制成的密封条 19, 此时， 当第一门板 13和第二门板 14 闭合时， 密封条挡 18抵靠在包裹在压缩弹性体 15外侧的密封条 19上， 这样可以进一步延长压缩弹性体 15的使用寿命。
另外， 如图 3A和图 3B所示， 据本发明的另一实施例， 不在第一 门板 13和第二门板 14的端部设置翻边，而是在第一门板 13和第二门板 14上设置支撑部件， 即在第一门板 13上固定设置第一支撑部件 20, 在 第二门板 14上固定设置第二支撑部件 21。第一支撑部件 20用于将压缩 弹性体 15固定在所述第一门板 13的端部外侧。 具体地， 第一支撑部件 20包括垂直设置的第一连接板 201和第一密封板 202， 第一连接板 201 固定设置在第一门板 13上。 第一支撑部件 20可以是金属材料， 其中第 一连接板 201可以焊接在第一门板 13上。 可以理解地， 第一连接板 201 和第一密封板 202之间还可以成斜角设置， 例如第一密封板 202可以向第 二门板 14倾斜以进一步压缩上 缩弹性体 15， 增强密封«。
第二支撑部件 21 包括垂直设置的第二连接板 211 和第二密封板 212,第二密封板 212与压缩弹性体 15相对设置， 当第一门板 13和第二 门板 14闭合时， 第二密封板 212抵靠在压缩弹性体 15上。 第二连接板 211固定设置在第二门板 14上， 优选的可以采取焊接的方式固定。 可以 理解地， 第二连接板 211和第二密封板 212之间还可以成斜角设置， 例如 第二密封板 212可以向压缩弹性体 15倾斜以增加压缩量， 增强密封效果。 如图 3A所示，可以在第二支撑部件 20的第二密封板 212上设置突 出的密封条档 18, 该密封条档 18与压缩弹性体 15相对设置， 当第一门 板 13和第二门板 14闭合时， 密封条档 18抵靠在压缩弹性体 15上。 该 密封条档 18的具体结构和材料与上述实施例相同， 在此不再赞述。
对于使用第一支撑部件 20将压缩弹性体 15固定在所述第一门板 13 的端部外侧， 可以通过两种方式实现。 在第一种方式中， 如图 3A所示， 压缩弹性体 15直接固定设置在第一密封板 202外侧，具体地可以采取铆 接的方式固定。 在图 3A所示的实施例中， 压缩弹性体 15的外侧还可以 包裹有耐磨材料密封条， 以提高压缩弹性体 15的耐磨性能， 当第一门板 13和第二门板 14闭合时， 密封条档 18抵靠在压缩弹性体 15外侧的耐 磨材料密封条上。
在第二种方式中， 如图 3B所示，， 压缩弹性体 15外包裹有带状的 耐磨材料制成的密封条 19。 具体的， 带状的密封条 19的两侧边夹持在 第一连接板 201与所述第一门板 13之间，且上述的带状的耐磨材料制成 的密封条 19将压缩弹性体 15包裹在所述第一支撑部 20的第一密封板 202外侧。 当第一门板 13和第二门板 14闭合时， 密封条档 18抵靠在压 缩弹性体 15外侧的带状密封条 19上， 因此进一步提高了压缩弹性体 15 的耐磨性能， 并延长了压缩弹性体 15的使用寿命。
相对于在第一门板的端部和第二门板的端部设置翻边以固定压缩弹 性体的技术方案， 这种通过第一支撑部件和第二支撑部件将压缩弹性体 固定在第一门板和第二门板之间的技术方案 , 对第一门板和第二门板的 改动较小， 第一门板和第二门板在制作过程中不需要压型， 可以降低模 具成本。
本发明上述各个实施例中， 为方便说明， 都是在第一门板上设置压 缩弹性体， 可以理解地， 同样可以在第二门板的端部设置压缩弹性体， 而对第一门板作相应的改进， 以实现第一门板和第二门板之间的密封性

本发明还提供了一种漏斗车 , 该漏斗车包括车厢体和上述的车辆卸 货门， 其中的车辆卸货门固定设置在上述车厢体的底部。 具体地， 车辆 卸货门的两个门轴铰接在上述车厢体的底部。
本发明上述各个实施例中 , 通过在车辆卸货门的第一门板和第二门 板之间设置弹性压缩体实现密封功能， 相对于现有技术中采用搭接的方 式对卸货门进行密封 , 不仅省略了用于控制第一门板和第二门板关闭顺 序的控制部件， 使得结构简单， 同时还能够提高密封性能。 以上所述仅是本发明的示例性的实施方式， 应当指出， 对于本技术 领域的普通技术人员来说， 在不脱离本发明原理的前提下， 还可以做出 若干改进和润饰。 本发明的保护范围以后附的权利要求为准。
