Description

中型电动车辆的可拆卸高压隔离结构 技术领域
本发明涉及一种可拆卸的高压隔离结构， 更确切的说， 本发明涉及一种将中型电 动车辆上所有的高压组件整合在一可拆卸的结构中。 背景技术
现今的中型电动车辆将许多内燃车辆上的设备改为电力驱动，此举造成车上有许 多高压组件散布在车辆各处。现有的车辆维修人员并未受过高压电相关的训练， 因此 无法安全的检修高压组件， 也无法确保在检修其它组件时不会意外触电。
也由于现有的车辆维修人员无法检修高压组件，导致车辆制造商必须提供大量的 售后服务， 并在车辆故障时派遣维修人员协助检修， 额外增加许多人力成本。
当车辆发生意外时， 若车门被阻碍， 救难人员必须将车体破坏以执行救援。 若车 辆有高压电缆及高压组件散布在车体各处， 不仅大幅增加救难人员的风险， 还容易延 误救援时机。
散布各处的高压组件及高压缆线同时也造成屏蔽的困难，在产生大范围的电磁波 影响乘员健康的同时， 也容易被其它的电磁波所干扰。
发明内容
鉴于现有中型电动车辆在检修、 救援及电磁波屏蔽的缺陷， 本发明希望通过车 辆结构的改善， 有效地避免维修及救援时的潜在危险， 并妥善屏蔽电磁干扰。
本发明的目的在于：

请参阅图 1、 图 3、 及图 4， 所述附图分别示出本发明的第一实施例的具有可拆卸 高压隔离结构的车辆结构的示意图、 局部详图和外观示意图。 底盘 101 由前轴 102 及后轴 103 支撑， 前悬吊 104 装置于底盘 101 与前轴 102之间， 以乘载车体的重 量； 后悬吊 105装置于底盘 101 与后轴 103 之间， 用以乘载车体的重量。 在后轴 103 上设有一差速器 303 用以将动力分散至车辆的左后轮及右后轮。
在底盘 101 后端设有一可拆卸的隔离结构框架 106，以容纳高压组件。底盘 101 后端另设有一可承重的导轨 108 ， 用以承受隔离结构框架 106 的重量。 隔离结构 框架 106 上设有滚轮 107 ， 与导轨 108 接触， 以便利拆装。
底盘 101 上设有一高压电池组 1 12 以供应车辆所需的高压电源， 并设有高压 电缆 1 13 以将高压电源由高压电池组 1 12 输送至隔离结构框架 106 内部。 高压电 缆 1 13 与隔离结构框架 106 以可拆卸的高压缆线接头 1 1 1 衔接。
隔离结构框架 106 内， 设有一动力马达 301 ; 该动力马达 301 负责产生推动 车辆所需的扭力， 经由可拆卸的传动轴接头 109 与传动轴 302 连接， 并经由传动 轴 302 将其产生的扭力送入差速器 303。
底盘 101 上设有一转向辅助泵 313 用以提供动力方向盘所需要的液压油； 隔 离结构框架 106 内， 设有一转向辅助马达 304 ， 用以转动转向辅助泵 313。 转向 辅助马达 304 通过可拆卸的转向辅助泵接头 1 10 与转向辅助泵轴心 312 连接， 并 经由转向辅助泵轴心 312 将扭力送入转向辅助泵 313。
底盘 101 上设有一空调压缩机 1 15， 用以产生冷气； 隔离结构框架 106 内另 设有一空调马达 305， 用以转动空调压缩机 1 15。 空调马达 305 通过可拆卸的空调 压缩机接头 1 14 与空调压缩机 1 15 连接， 并经由空调压缩机轴心 322 将扭力送入 空调压缩机 1 15。
隔离结构框架 106 内， 设有一空气压缩机 309 以提供车辆所需要的压缩空气； 隔离结构框架 106 内另设有一空气压缩机马达 310， 以驱动空气压缩机 309。
隔离结构框架 106 内， 设有一左侧冷却道 307 及一右侧冷却道 308， 负责将 内部的热量排出。
隔离结构框架 106 中， 设有一马达驱动器 31 1 用以供应电力给各马达。 隔离 结构框架 106 的上， 装设有多个电磁波屏蔽板 401 以隔绝电磁干扰。
此实施例所公开的设计概念， 主要为一妥善隔离的高压隔离结构， 将所有含有高 压电的设备皆整合在内， 使用各种方法妥善隔离并提供一易拆装的分离点。 同时， 在 车辆需检修时， 可在尽量不接触到高压组件的情况下， 将隔离结构完整拆除， 已将维 修人员的风险降到最低。 同时通过整合高压组件， 将高压电缆的数量减到最少， 以便 意外发生时救难人员可安全的破坏车体。
隔离结构中， 最主要的高压组件为动力马达。 由于马达外壳与内部高压线圈之间 为绝缘， 因此只须将马达外壳与隔离结构框架接地即可。在结构上选择了可拆卸的传 动轴接头， 以便将马达与车上的机械结构分离。
另一常见的高压组件为冷气压缩机；现有的中型电动车辆大多选择使用置顶式冷 气。 置顶式冷气虽然安装便利， 但也代表必须将高压电送到车顶区域； 为了供应该高 压电源， 车身侧板中也必须有高压电缆。 车辆发生意外时， 极有可能因高压电缆破损 而导致成员触电。本实施例将空调压缩机装置在底盘上， 并将空调压缩机的驱动马达 装设在隔离结构中， 通过一可拆卸的接头将两者连接。 在拆卸时， 空调压缩机及空调 马达之间为分离点。
另一不可或缺的高压组件为动力方向盘。现有中型电动车辆多采用传统油压的动 力方向盘， 并在驾驶座附近设置一电动泵； 这样的设计将导致驾驶座附近必须配置高 压缆线。 本实施例依然使用油压式的动力方向盘， 但通过将转向辅助泵安装在车尾， 并通过装设在隔离结构中的马达驱动；此设计可有效避免驾驶座附近配置高压缆线需 求。 与动力马达相同， 转向辅助马达的内部高压线圈与外壳之间同样为绝缘， 并使用 转向辅助马达与转向辅助泵之间为分离点。
同样的， 空气压缩机也设置在隔离结构中； 空气压缩机通过一绝缘空气管与车上 的空气储存槽连接， 该绝缘空气管可作为气压系统的分离点。
由于此实施例会使用电磁波屏蔽板将隔离结构密封，因此在冷却系统的选用上须 使用集中式的冷却。将隔离结构中所有需要冷却的组件以冷却水冷却， 再将冷却水带 到左侧冷却道及右侧冷却道中降温， 以排出热量。 也由于隔离结构为一密封结构， 因 此若结构中装设有内燃发电机， 内燃机产生的热将容易造成隔离结构内部过热。在此 实施例中， 若须配置内燃发电机， 则会将内燃发电机装设在冷却道中， 使该发电机能 与隔离结构一并被拆除但不会导致隔离结构内部温度过高。
在车辆维修时， 此架构也可确保维修人员的安全。 当车辆故障时， 可通过故障码 先分辨是否是此隔离结构内部的组件故障。若是隔离结构内部的组件故障， 则将隔离 结构完整拆除并换上备品， 并将故障的隔离结构整个送回原厂检修。若是隔离结构外 的组件故障， 则维修人员可放心维修； 如欲更加提高安全性， 可在维修时将隔离结构 暂时拆除。利用隔离结构清楚界定高压组件的范围是对维修人员的保护， 同时也减少 了原厂需派遣人员协助检修的需求。 当车辆发生事故时， 若需破坏车体以进行救援， 必须确保被破坏的部位并不包含 高压电。 由于所有高压组件已被整合并隔离， 因此救难人员只需要避开高压电池组、 高压电缆、 及高压隔离结构即可确保不会触电。 更确切的说， 由于高压电池组、 高压 电缆、及高压隔离结构都在底盘上，因此车顶及侧壁不会有任何高压组件或高压缆线。
此实施例同时也公开了一个易于屏蔽电磁干扰的设计概念； 将高压组件整合， 可 有效的减少高压电缆的长度， 进而减少因电缆而产生的电磁干扰。 同样的， 通过将所 有高压组件整合在一个框架内， 只需对框架整体作屏蔽， 即可有效的减少因马达及驱 动器所产生的电磁干扰。
此隔离架构在实施时， 若情况许可， 应在车室内设置多个维修孔， 经由打开维修 孔即可拆卸马达接头、 转向辅助泵接头、 高压空气管、 空调压缩机接头、 高压缆线接 头、及其它相对应的分离点， 可使车辆在无需顶高设备的情况下快速拆装整组高压隔 离结构， 以便厂内施工或路边紧急维修。 隔离结构在拆卸时， 只需将各连接点拆开， 将隔离结构与底盘分离， 即可通过导轨及导轮将隔离结构拉出。
请参阅图 2， 示出本发明的第一实施例的具有可拆卸高压隔离结构的车辆结构的 示意图。 底盘 201 由前轴 202 及后轴 203 支撑， 前悬吊 204 装置于底盘 201 与 前轴 202之间， 以乘载车体的重量； 后悬吊 205装置于底盘 201 与后轴 203 之间， 用以乘载车体的重量。
底盘 201 后端设有一可拆卸的隔离结构框架 206， 以容纳高压组件。 底盘 201 后端另设有一可承重的支撑杆 214 ， 用以承受隔离结构框架 206 的重量。 隔离结 构框架 206 上设有定位销 208 ， 与定位槽 207 接触， 以便利拆装。
底盘 201 上设有一高压电池组 212 以供应车辆所需的高压电源， 并设有高压 电缆 213 以将高压电源由高压电池组 212 输送至隔离结构框架 206 内部。 高压电 缆 213 与隔离结构框架 206 以可拆卸的高压缆线接头 21 1 衔接。 转向辅助泵接头 210 用以将扭力提供给转向辅助系统。 底盘上设有一空调压缩机 215 用以提供冷空 气； 空调压缩机接头 214 用以将扭力提供给空调压缩机 215。
实施例二与前述的实施例一内部结构相同，其主要的特征为使用定位槽与定位销的结 合来便利拆装， 且采用悬挂结构。 若要便利拆装， 可在支撑杆上增设小型吊车。 拆卸时， 只需以小型吊车将隔离结构垂降至地面及可将隔离结构拖出； 安装时， 只需将隔离结构滑 入支撑杆下方， 以小型吊车吊升后， 即可将隔离结构与支撑杆及底盘锁固。
