本发明的目的是克服现有技术中存在的不足，提供一种把前进风口布置在 箱式隔音罩组合前端面，控制器布置在前端面里侧， 利用冷却进风对控制器的 2个面积大的大面和侧面直接通风冷却， 又阻挡发电机噪音从隔音罩进风口泄 漏，反射从风扇进风口出来的噪音； 发电机的前后风道按零件工作温度从低到 高逐级冷却，对温度最高的发动机和消声器进行分段冷却，增大消声器的容积 进行分段布置但不增加发电机总成体积的结构，减少隔音罩开口大幅度降低发 电机总成噪音， 还要方便生产者、 用户对箱式发电机的操作、 安装和维护的箱 式发电机。
为了达到这样的目的， 本发动机驱动的箱式发电机采用这样的布置方案： 一种发动机驱动的箱式发电机，整个发电机总成由至少两块隔音罩拼装组 合的箱式隔音罩组合包容，箱式隔音罩组合内的发电机部件按冷却风的流向看 按照箱体隔音罩前端面下部的前进风口、 控制器、 前风扇和前风道、 永磁式发 电机、 发动机、 左右后进风口、 后风扇和后风道、 双腔式消声器组合的前后近 一条线的次序布置，前后风道和双腔式消声器组合在这条线上按前风道和消声 器上腔在上、后风道和消声器下腔在下的上下分开布置； 前进风口布置在前端 面，供前风道吸入冷却风，控制器布置在前端面里侧且大平面平行和覆盖前进 风口，控制器的上部是油箱，前风道冷却风按控制器、前风扇、永磁式发电机、 发动机气缸以上部分、双腔式消声器进气管和上腔体的顺序冷却； 箱式隔音罩 组合的左右隔音罩在前风扇进风口后靠近发动机空滤器和下箱体的部位开有 左右后进风口供后风道进风， 后风道冷却风按发动机气缸以下部分、 后风扇、 双腔式消声器下腔体的顺序冷却； 前后风道中的前后风扇、永磁式发电机均由 发动机直接驱动， 前后风道的冷却风流向均为从前向后。
控制器通过减震橡胶块直接落在隔音底罩上，控制器的上部是油箱，控制 器和油箱一起通过减震橡胶块与左右隔音罩、 隔音底罩固定； 控制器的左右边 与箱体左右隔音罩的内边有一定间隙以容许冷却风通过，控制器面积大的主冷 却面直接覆盖前进风口； 因为风扇的进风口就在控制器的后面， 箱体隔音罩的 左右 2个侧面靠前风扇进风口以前的部位没有除前进风口以外的进风口，所以 前冷却进风只能通过前进风口进入，先通过控制器带散热片的主冷却面，再通 过控制器侧面与箱体隔音罩、油箱的间隙绕到控制器反面的次冷却面， 然后从 风扇进风口吸入， 由于冷却进风必须环绕通过控制器的正反 2个大面和侧面， 冷却性能大大优于只冷却控制器主冷却面的结构，控制器的形状是扁平的长方 体， 面积大的 2个大面都可以选择面对和覆盖前进风口， 布置在前进风口和前 风扇之间； 同时由于控制器布置在前进风口和风扇进风口之间， 既反射从风扇 进风口泄漏出来的发电机噪音，又可以阻挡箱体隔音罩内的噪音从前进风口泄 漏出去， 有利于利用声音的漫反射来消声降噪。
双腔式消声器组合包括有上下两个腔体和进气管、连通管、 消声器出气口 等外部可见部件， 前风道组合包容前风扇、 永磁式发电机、 发动机的气缸以上 部分、 消声器进气管和上腔体部分； 后风道组合从左右后进风口进风经发动机 气缸以下部分的箱体、油底壳后被风扇吸风增压并包容冷却消声器下腔体； 前 风道组合通过紧固件和密封带与发动机气缸以上部分相连，消声器的上下腔体 与发动机、 后风道前罩用螺栓相连， 前后风道互不相连并有隔板分开； 这样发 动机前后 2个风扇的增压冷却风通过前后 2个风道组合分别逐次环绕冷却永磁 式发电机、 发动机、 双段式消声器的进气管和上、 下两个腔体、 连通管的外表 面， 前风道最后冷却双腔式消声器的的上腔体，后风道最后冷却双腔式消声器 的下腔体， 前后风道从双腔式消声器连接管处分隔互不相通， 消声器出气口被 排风口罩包容， 大大降低了永磁式发电机、发动机、 双段式消声器组合的本体 温度和消声器出气口处的排气温度，确保了发电机总成的消声冷却效果； 同时 由于前后 2个风道组合分别将风扇、 永磁式发电机、 发动机、 消声器组合的主 要发声部分包容，风道自身的隔音功能和上面的消声结构也可以降低发电机总 成的噪音。 为了防止发动机、 消声器组合自身的热辐射可能造成前后 2个风道 组合本体温度高而造成风道自身损坏，在前后 2个风道组合温度较高的局部内 壁部位贴有隔热反射膜， 为了提高前后 2个风道组合的隔音功能， 在前、 后风 道组合的内外壁局部位置还制造有消音结构和贴有消音棉。前、后风道组合在 双腔式消声器组合连通管处有隔板分隔， 互不相通。
箱式隔音罩组合由隔音左罩、 隔音右罩、 隔音底罩、 排风口罩、 维修门、 火花塞盖等组成，前进风口各有一部分直接做在隔音左罩和隔音右罩的前端面 上或单独制造前进风口罩组合装配在隔音左罩和隔音右罩上，箱式隔音罩组合 内的主要部件都直接、 间接的安装承载在隔音底罩上， 通过紧固件、 緩冲橡胶 件和密封带连接。 为了方便操作人员， 集合了所有与启动、 开关、 接电、 指示 有关的集成操作面板布置在箱式隔音罩组合侧面的一个罩上。隔音左罩和隔音 右罩合起来后的上部还有提手和加油口，隔音左罩和隔音右罩在内侧与油箱对 应位置还有油箱安装固定结构，箱式隔音罩组合各部件内侧的局部位置还有加 强筋和贴有消音棉、 密封带。

具体实施方式
下面参照附图说明本发明的具体实施方案：
如附图 1到附图 6的实施方式说明图所示，一种发动机驱动的箱式发电机， 整个发电机总成由几块隔音罩拼装组合的箱式隔音罩组合 3包容，内有控制器 2、 油箱 19、 前风扇 1 3、 前风道组合 11、 永磁式发电机 4、 发动机 5、 后风扇 14、 后风道组合 12、 双腔式消声器组合 6、 操作面板 27、 油泵 34等主要部件 组成。
箱式隔音罩组合 3内的发电机部件布置如附图所示，从前至后依次按前进 风口 1、 控制器 2、 前风扇 1 3和前风道组合 11、 永磁式发电机 4、 发动机 5、 后风扇 14和后风道组合 12、双腔式消声器组合 6、排风口罩 10的前后近一条 线的次序布置， 前风道组合 11和进气管 22、 消声器上腔体 20布置在上面， 后风扇 14和后风道组合 12、 消声器下腔体 21布置在下面， 使前后风道及包 容部件从发动机 5开始按上下分开布置。
发电机的冷却风流向按照附图的风向箭头所示， 前冷却风从隔音左罩 7、 隔音右罩 8前端面下部的前进风口 1处进来， 吹向控制器 2的主冷却面 15 , 环绕侧面和次冷却面 16被前风扇 1 3从前风扇进风口 17吸入前风道组合 11 , 然后逐次环绕通过冷却永磁式发电机 4、 发动机 5气缸以上部分、 进气管 22、 消声器上腔体 20外表面后从排风口罩 10的上半部排出；后冷却风从隔音左罩 7、 隔音右罩 8左右侧面的隔音左罩后进风口 32、 隔音右罩后进风口 33处进 来，先冷却发动机气缸以下部分，再被后风扇 14吸入后风道组合 12增压后环 绕通过双腔式消声器下腔体 21外表面冷却，从排风口罩 10的下半部排出； 前 风道组合 1 1、 后风道组合 12在双腔式消声器组合 6的连接管 23处有隔板分 隔， 互不相通， 且前后风道冷却风流向均为从前向后。
控制器 2通过减震橡胶块 18直接落在隔音底罩 9上， 控制器 2的上部是 油箱 19 ,控制器 2的左右边与隔音左罩 7、 隔音右罩 8的内侧面有一定间隙以 容许冷却风通过， 控制器主冷却面 15直接覆盖前进风口 1 ; 因为前风扇进风 口 17就在控制器 2的次冷却面 16的后面， 隔音左罩后进风口 32、 隔音右罩 后进风口 33在前风扇进风口 17后面， 所以前冷却进风只能通过前进风口 1 进入， 先通过控制器 2带散热片的主冷却面 15 , 再通过控制器侧面与隔音左 罩 7、 隔音右罩 8内侧面间的间隙绕到控制器次冷却面 16 , 然后从前风扇进风 口 17被前风扇 1 3吸入前风道组合 11 , 由于冷却进风必须环绕通过控制器 2 的主冷却面 15、 次冷却面 16和侧面， 冷却性能大大优于只冷却控制器主冷却 面的结构， 同时由于控制器 2布置在前进风口 1和前风扇进风口 17之间， 既 可以反射从前风扇进风口 17泄漏出来的发电机噪音， 又可以阻挡箱式隔音罩 组合 3内的噪音从前进风口 1泄漏出去，有利于利用声音的漫反射来消声降噪。
双腔式消声器组合 6包括有消声器上腔体 20、 消声器下腔体 21、 进气管 22、 连接管 23、 出气口 24等外部可见部件， 前风道组合 11包容前风扇 1 3、 永磁式发电机 4、 发动机 5的气缸以上部分、 消声器进气管 22和消声器上腔 体 20部分； 后风道组合 12从隔音左罩后进风口 32、 隔音右罩后进风口 33进 风， 沿发动机 5气缸以下部分的箱体、 油底壳处通过后被后风扇 14吸风增压 并包容冷却消声器下腔体 21外表面；前风道组合 11通过紧固件和密封带与发 动机 5气缸以上部分相连， 双腔式消声器组合 6的上下腔体与发动机 5、 后风 道组合 12用紧固件相连； 消声器出气口 24被排风口罩 10包容； 这样发动机 5的前风扇 1 3、 后风扇 14的增压冷却风通过前风道组合 1 1、 后风道组合 12 分别环绕冷却永磁式发电机 4、 发动机 5、 双腔式消声器组合 6的外表面， 大 大降低了永磁式发电机 4、 发动机 5、 双腔式消声器组合 6的本体温度和消声 器出气口 24处的排气温度， 有利于提高发电机总成的消声冷却效果， 同时由 于前后风道冷却的零部件温度都是从低到高的， 没有把冷却风几处分流，提高 了风扇的总体工作效率，也减少了发电机高温件辐射热给低温件； 同时由于前 风道组合 11、 后风道组合 12分别将前风扇 1 3、 永磁式发电机 4、 发动机 5、 后风扇 14、 双腔式消声器组合 6的主要部分包容， 风道自身的隔音功能和上 面的消声结构也可以降低发电机总成的噪音。 为了防止发动机 5、 双腔式消声 器组合 6 自身的热辐射可能造成前风道组合 11、后风道组合 12本体温度高而 造成风道自身损坏， 在前风道组合 11、 后风道组合 12温度较高的局部内壁部 位贴有隔热反射膜 35 , 为了提高前风道组合 11、 后风道组合 12的隔音功能， 在前风道组合 1 1、 后风道组合 12的内外壁局部位置还制造有消音结构 36和 贴有消音棉 29。
箱式隔音罩组合 3由隔音左罩 7、 隔音右罩 8、 隔音底罩 9、 排风口罩 10、 维修门 25、 火花塞盖 26、 操作面板 27等组成， 前进风口 1各有一部分直接做 在隔音左罩 7和隔音右罩 8的前端面上，上述部件通过密封连接结构和紧固件 组合形成箱式隔音罩组合 3。 其中的隔音底罩 9是主要的承载件， 控制器 2和 内发电体 40、 还有油泵 34都通过緩冲、 紧固件直接安装在隔音底罩 9上， 隔 音左罩 7、 隔音右罩 8承载了油箱 19、 一体式操作面板 27、 排风口罩 10、 维 修门 25、 火花塞盖 26等部件后也直接安装在隔音底罩 9上， 这样的结构非常 便于分部件的组装和日常的维护保养， 只要松开维修门 25就可以进行空滤器 保养和发动机 5 机油更换、 化油器调整等日常维护保养工作， 松开火花塞盖 26就可以检查更换火花塞，松开隔音左罩 7、 隔音右罩 8的紧固件就可以方便 的接触到发电机内部的各总成件和线路、 油管、 拉索等， 同样装配起来互相关 联的部件也少，对装配技术和专门装备的要求低， 不会产生许多箱式发电机隔 音罩组合一拆开许多部件就分散开来难以组装的问题。为了方便使用和提高消 声效果， 隔音左罩 7和隔音右罩 8合起来后的上部还有提手 30和加油口 31 , 隔音左罩 7和隔音右罩 8在内侧与油箱 19对应位置还有油箱安装固定结构， 油箱 19上部是加油口 31 , 隔音左罩 7和隔音右罩 8、 隔音底罩 9、 排风口罩 10、 维修门 25、 火花塞盖 26内侧的局部位置还有加强筋 28和贴有消音棉 29 以提高强度和消音效果。
为了方便用户操作， 集合了所有与启动、 开关、 接电输出、 指示有关的一 体式操作面板 27就布置在箱式隔音罩组合 3的隔音左罩 7上， 这样使用人员 既避免了像使用常见的箱式发电机那样启动停止发电机要在发电机周边几个 面分别按程序操作一圈，往往忘这忘那的问题， 又可以减少使用时需要的周边 空间， 还便于把控制器 2的电线、 风门拉索线 37、 油管 38直接接到操作面板 27处； 同时由于本发明把操作面板 27的底板与隔音左罩 7直接做成一体， 既 提高了隔音左罩 Ί 的强度， 又减少了面板开口和常见的操作面板底罩这个零 件， 这样的设计大大简化了箱式隔音罩组合 3各部件的结构， 减少了隔音罩上 的开口和阻断了声音从开口漏出， 易于进行新颖美观的外观设计。 由于油电总 开关 39把总油开关和总电开关集成在一起并布置在油箱 19底面以下，可以保 证在打开关闭油电总开关 39时可以同时打开关闭汽油和电路总开关， 既简化 了操作又防止了关一个忘记关另一个开关的风险， 还可以保证油电总开关 39 打开后汽油可重力供油直达油泵 34的进油口， 油泵 34又布置在化油器 36下 面附近， 大大减少了第一次启动时靠手拉启动来泵油的拉动次数； 这些人性化 的设计都非常有利于普通用户的轻松使用，也降低了对用户使用技能、场地的 要求， 还有利于发电机总成噪音的降低。
