本发明涉及一种电动车的电池模块配置结构，尤指一种电动大客车的电池模块配置结 构。 背景技术
随着环保节能观念的盛行， 电动车的相关研发随之蓬勃发展。 一般而言， 电动车的动 力源即来自于其车身内的电池模块， 为了使电动车能够被驱动及达到一定的续航力， 通常 须配置多组电池模块以供应足够的动力，而多组电池模块的配置势必会占据电动车相当的 空间， 因此电动车的电池模块配置结构与方式便成为待研发的课题。
一般而言， 不同种类或车型的电动车因其功能、硬件条件以及各国的安全规范不同而 使得其电池模块配置结构与方式亦不同。 小型电动车， 例如电动小客车， 的多组电池模块 通常配置于其车体的后车厢区域。 然而， 作为大众运输工具用途的大型电动车， 例如电动 大客车 (或称电动巴士)， 通常具有较大且较重的车身， 因此需要使用容量较大、体积较大、 重量较重且数量较多的电池模块以提供足够的动力及续航力。 以往， 由于电池研发的瓶颈 及相关硬件设备， 例如充电站或电池交换站等， 开发的不足， 导致电动大客车的研发及投 入较为稀少且迟缓。 近年来， 由于电池技术的突破及相关硬件建置的补强， 已使电动大客 车的研发与应用得以逐渐实现。 目前， 电动大客车的研发多为长度约 12公尺的电动巴士， 且其多组电池模块通常配置于其车体内，并且设置于其前轮轴及后轮轴之间的走道的两侧 区域。为了维持一定的座位数， 目前电动大客车于其多组电池模块的上方会设置多个座位 (亦即走道两侧的多个座位设置于多个电池模块的上方)， 如此将使得电动大客车的座位皆 需垫高一定的高度进而影响乘客于行车中乘座的舒适性，且电动大客车需设置阶梯于其出 入口或其座位旁， 如此乘客于上下车时皆需使用阶梯， 导致乘客上下车的时间增加， 影响 电动大客车的行车时间， 且不利于轮椅进入。 此外， 当电动大客车于行驶中涉水或遭受雨 水泼淋时， 其电池模块的配置位置与方式容易使得电池模块受潮或受水气侵入， 进而影响 电池模块的使用寿命及电动大客车的运作安全。 再则， 当电动大客车受到撞击或事故时， 其电池模块的配置位置与方式亦会使其受损的机率增高。此外， 电动大客车的电池模块配 置结构与方式亦会使得车架或其底盘于长期使用后产生形变，进而影响车体的结构与行车 安全。更甚者， 电动大客车的电池模块配置位置与方式亦无法直接利用车体的空调系统来 提升其散热效率。
近年来， 双节式大客车 (Articulated Bus)因具有更大的运载能力， 且可减少捷运或轻轨 等高成本的硬件建设的支出， 而逐渐地为各国所推广与应用。双节式大客车由两刚性车厢 所连结而成， 其总长度约 18公尺左右， 且乘客可如同搭乘于捷运车厢般于其两刚性车厢 间移动， 并且可同时运载约 120人〜 200人。 双节式大客车通常被使用于市区或机场接驳， 以取代捷运或轻轨等轨道车辆而作为快速、大量及短距离运载乘客的大众运输工具。有鉴 于此， 双节式大客车通常为低底盘 (Low floor)形式， 所谓的低底盘是指从第一刚性车厢的 驾驶座旁的前门起， 沿着第一刚性车厢的走道至第二刚性车厢的轮轴区域之前的走道为 止， 其地板为平面且全车走道无阶梯。 换言之， 乘客上下车及乘座于座位时无需经过阶梯 而可快速地上下车及就座， 且轮椅可以进入。 然而， 目前双节式电动大客车的研发与应用 仍付之阙如， 且于开发双节式电动大客车时亦需依据公共运输的要求、车体的硬件条件与 限制、 各国的通用规范、 电池能量换补的迅速性与方便性、 乘客的便利与安全性、 空间利 用率而考量其多组电池模块的配置结构与方式， 并且可以降低及避免前述问题的发生， 因 此如何发展一种双节式电动大客车的电池模块配置结构实为目前急待解决的问题。 发明内容

双节式电动大客车 1更包括第一轮轴 14(或称前轮轴)、第二轮轴 15(或称中轮轴)以及 第三轮轴 16(或称后轮轴)， 其依序设置于车体 10的底部。 于本实施例中， 第一轮轴 14及 第二轮轴 15设置于第一刚性车厢 11的底部，且第三轮轴 16设置于第二刚性车厢 12的底 部。 此外， 双节式电动大客车 1的车体 10从其车头至车尾的方向可依序区分为车头区段 100、 前轮轴区段 101、 第一车身区段 102、 中轮轴区段 103、 连结单元区段 104、 第二车 身区段 105、 后轮轴区段 106及车尾区段 107。 其中， 第一轮轴 14及第二轮轴 15分别对 应于车体 10(或第一刚性车厢 11)的前轮轴区段 101及中轮轴区段 103而设置， 使车体 10 的前轮轴区段 101及中轮轴区段 103分别具有两个第一高台部 108及两个第二高台部 109， 其中两个第一高台部 108彼此相对且位于车体 10的走道 17的两侧， 以及两个第二高台部 109彼此相对且位于车体 10的走道 17的两侧。 第三轮轴 16对应于车体 10(或第二刚性车 厢 12)的后轮轴区段 106而设置， 使车体 10的后轮轴区段 106具有两个第三高台部 110， 其中两个第三高台部 110彼此相对且位于车体 10的走道 17的两侧。于本实施例中， 车体 10的前轮轴区段 101、 中轮轴区段 103及后轮轴区段 106的两个第一高台部 108、 两个第 二高台部 109及两个第三高台部 110的上方分别对应地设置电池容收箱 201、 202、 203， 借此多个电池模块 20可抽换地容收于该多个电池容收箱 201、 202、 203的容置空间中。 换言之，车体 10(或第一刚性车厢 11及第二刚性车厢 12)内配置多个电池容收箱 201、 202、 203， 其对应于第一轮轴 14、 第二轮轴 15及第三轮轴 16而设置， 且位于第一轮轴 14、 第 二轮轴 15及第三轮轴 16上方。 多个电池容收箱 201、 202、 203可邻设于车体 10的两侧 边， 借此多个电池模块 20可抽换地容收于该多个电池容收箱 201、 202、 203。
图 3显示本发明较佳实施例的双节式电动大客车于其电池模块进行抽换的示意图。于 一些实施例中， 车体 10的两侧边对应于多个电池容收箱 201、 202、 203的位置分别具有 门板 204、 205、 206。 当多个电池模块 20分别容收于多个电池容收箱 201、 202、 203的容 置空间时， 该多个门板 204、 205、 206可锁固以封闭多个电池模块 20。 当多个电池模块 20的电力消耗至一定程度时， 可进行多个电池模块 20的抽换作业， 借此使双截式电动大 客车 1 的使用效率提高， 且不需整车充电造成使用效率降低。 当欲抽换多个电池模块 20 时， 可从车体 10外部将车体 10的两侧边的门板 204、 205、 206解锁并开启， 借此可利用 人工或自动机械化的作业方式于一电池换装站将多个电池模块 20移出车体 10外，并将待 换入的多个电池模块 20置入于多个电池容收箱 201、202、203的容置空间中且将门板 204、 205、 206锁固， 如此便可快速、 安全且方便地完成多个电池模块 20的换装作业。 于一些 实施例中， 电池模块 20的数量可依实际施作情形而任施变化， 并不以此为限。
于本实施例中， 双节式电动大客车 1可为低底盘双节式电动大客车， 其中所谓的低底 盘是指其车体 10内的地板为一平面且全车走道 17无阶梯， 其中走道 17延伸于车头区段 100、 前轮轴区段 101、 第一车身区段 102、 中轮轴区段 103、 连结单元区段 104、 第二车 身区段 105及后轮轴区段 106， 但不以此为限。换言之， 从第一刚性车厢 11的驾驶座旁的 前门起， 沿着第一刚性车厢 11、 连结单元 13及第二车厢 12的走道 17， 直至第二刚性车 厢 12的第三轮轴 16(亦或后轮轴区段 106)之前为止， 其车体 10内的地板为平面且全车走 道 17无阶梯。 此外， 双节式电动大客车 1从其车体 10的底盘至地面的高度约 15公分且 其车体 10内的地板至地面高度约 35公分， 但不以此为限， 借此乘客 30于搭乘双节式电 动大客车 1时， 双节式电动大客车 1的底盘空间可变为低底盘形式， 以方便乘客 30不需 经过阶梯上下车， 轮椅也可方便进出。
