随着市场混合动力系统配置车型的普及和国家排放油耗要求，混合动力系统配置在不同的车型架构时，混合动力系统的结构存在很大的差异,不同的车型架构需要搭载不同样式的混合动力系统，这会造成车型的开发周期加长，增加配件管理的难度，使单个混合动力汽车的固有成本的增加。

详述
本公开描述了多个实施例，但是该描述是示例性的，而不是限制性的，并且对于本领域的普通技术人员来说显而易见的是，在本公开所描述的实施例包含的范围内可以有更多的实施例和实现方案。
本公开的描述中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开中被描述为“示例性的”或者“例如”的任何实施例不应被解释为比其他实施例更优选或更具优势。本文中的“和/或”是对关联对象的关联关系的一种描述，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。“多个”是指两个或多于两个。另外，为了便于清楚描述本公开实施例的技术方案，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
在描述具有代表性的示例性实施例时，说明书可能已经将方法和/或过程呈现为特定的步骤序列。然而，在该方法或过程不依赖于本文所述步骤的特定顺序的程度上，该方法或过程不应限于所述的特定顺序的步骤。如本领域普通技术人员将理解的，其它的步骤顺序也是可能的。因此，说明书中阐述的步骤的特定顺序不应被解释为对权利要求的限制。此外，针对该方法和/ 或过程的权利要求不应限于按照所写顺序执行它们的步骤，本领域技术人员可以容易地理解，这些顺序可以变化，并且仍然保持在本公开实施例的精神和范围内。
混合动力系统包括发动机、变速系统、动力电池等主要设备。
混合动力系统中，变速箱和发动机通常集成在一起，对成本有一定优势，但是通用性差。如果车型架构不同，所需的混合动力系统的功率、转矩提升，或者排放、油耗的要求不同，就需要重新开模设计不同样式的混合动力系统，造成车型的开发周期加长，配件管理难度大，固有成本增加；
混合动力系统中，动力电池放置在汽车的后备箱位置，随着能量、功率需求的增大，动力电池的体积也会增大，占用了后备箱的使用空间，使后备箱的可用空间变小。而且，不同车型架构下的动力需求不同，动力电池的尺寸也会相应变化，使得安装动力电池的架构支架位置和所占用的空间大小不同，不利于动力电池的安装和互换性。
混合动力系统中，功率控制单元与变速系统集成在一起，功率控制单元和动力电池之间通过线束插件连接。随着混合动力系统的配置和安装位置的变化，线束插件的安装接口及折弯的形状也需要相应改变，使得线束插件的通用性和互换性存在问题，达不到即插即用的目的。
本公开一实施例提供了一种混合动力系统的模块化组件，包括：
多种发动机，均设有第一连接接口；
多种包括变速箱的变速系统，均设有第二连接接口；
所述多种发动机和多种变速系统可构成用于混合动力系统的多种动力包，其中，任一种发动机和任一种变速箱可基于各自的第一连接接口和第二连接接口相互连接，组装为包括发动机和变速系统的一种动力包。
本实施例的模块化组件可以根据需要应用于各种混合动力汽车的车型架构，在充分分析各模块化组件结构特点的条件下，开发若干发动机和若干变 速系统，再通过不同的组合来满足现在和将来各种车型对动力性、经济性、排放和油耗的不同要求，只需要开发M种发动机和N种变速系统就可以得到M×N种动力包，适应于各种各样的车型对混合动力系统的要求。对不同的车型，通过改变组装的一个或多个模块化组件就能满足设计要求，从而缩短车型的开发周期，减少配件管理的难度，使得单个混合动力汽车的成本也相应减少。
如图1所示，是一种示例性的混合动力系统的模块化组件，包括5种发动机和2种变速系统，其中，5种发动机分别是第一发动机11、第二发动机12、第三发动机13、第四发动机14和第五发动机15，2种变速系统分别是第一变速系统21和第二变速系统22。5种发动机均设有第一连接接口，2种变速系统均包括变速箱，均设有第二连接接口。本实施例的第一连接接口和第二连接接口均是通用的接口，也就是说，任一种发动机的第一连接接口可以与任一种变速系统的第二连接接口相互连接。
基于连接接口的通用性，任一种发动机和任一种变速箱可基于各自的第一连接接口和第二连接接口相互连接。例如：第一发动机11和第一变速系统21可以组装为第一种动力包，第一发动机11和第二变速系统22也可以组装为第二种动力包，第二发动机12和第一变速系统21可以组装为第三种动力包，第二发动机12和第二变速系统22可以组装为第四种动力包，依次类推，一共可以组装出10种动力包，进而得到10种动力包不同的混合动力系统。需要说明的是，在使用模块化组件的混合动力系统中也可以包括非模块化的组件，例如基于图1的示例，也可以设计一种发动机，该发动机只能够与第一变速系统组装，不能够与第二变速系统组装，或者设计一种变速系统，这种变速系统只能够与第一发动机和第二发动机组装为动力包，不能够与其他发动机组装，这些组件不具有通用性，不属于本公开的模块化组件。容易理解，最小的模块化组件包括2种发动机和2种变速系统，可以任意组合为至少4种动力包。
本实施例中，所述多种发动机中，不同的发动机之间至少有以下一种或多种参数不同：功率、转矩、压缩比、缸数、气门数、排量、气缸排列方式。 在一个示例中，多种发动机的功率不同，覆盖了70KW-180KW的功率范围，例如分别是70KW、90KW、110W、150KW、180KW，在另一示例中，多种发动机的功率也可以有部分相同，但功率相同的发动机的转矩不同，例如5种发动机的功率分别是70KW、90KW、90W、120KW、150KW，其中一种90KW的发动机的转矩为1500Nm，另一种90KW的发动机的转矩为2000Nm。所述多种变速系统中，不同的变速系统的混动构型不同，例如可以是档位的数量不同，各档的变速比不同，驱动方式不同(如串联式、并联式、混联式、功率分流式)，等等
如上所述，本实施例作为模块化组件的任一发动机和任一变速箱是通过各自的第一连接接口和第二连接接口组装在一起的，也就是说，发动机和变速箱具有独立的外壳。发动机和变速箱之间需要进行动力传递，因此第一连接接口和第二连接接口需要实现传动功能。
在一示例性实施例中，所述第一连接接口包括可拆卸连接于所述发动机的飞轮的第一传动件；所述第二连接接口包括可拆卸连接于所述变速箱的传动轴的第二传动件；所述第一传动件和第二传动件均有多种，其中相互匹配的第一传动件和第二传动件构成多种传动件组合，分别用于实现所述多种动力包中发动机和变速箱之间的动力传递。举例来说，一个变速系统与不同的发动机连接时，由于要传递的动力大小不同，出于机械强度和成本等考虑，使用同样的机构来实现动力的传递不是最佳的选择，而本实施例可以通过更换不同的传动件组合，来实现不同动力包中发动机和变速系统的动力传递。需要说明的是，这并意味着不同动力包一定要使用不同的传动件组合来实现动力传递，例如10种动力包，可以使用10种不同的传动件组合，也可以只使用2～9种不同的传动件组合来传递动力。
在一示例性实施例中，为了节约成本和更换传动件组合的便捷性。所述传动件组合中的第一传动件和第二传动件中的一个包括花键轴，另一个包括花键轴套，花键轴和花键轴套分别与发动机和变速系统的传动部件连接，发动机和变速系统之间的动力传递通过花键轴和花键轴套配合实现。
一个示例性的第一传动件18的立体图如图3所示，第一传动件18包括 花键轴套181和底盘182，底盘182上周向间隔设置有多个安装孔183，用于与螺栓配合将底盘182固定安装在发动机的飞轮上，花键轴套181设置在底盘182中部的一侧，花键轴套181和安装孔183之间的底盘182上还开设有几个圆形的通孔185，用于穿设螺栓。花键轴套181的壁厚从远离底盘182的一端到连接底盘182的一端逐渐增大，以确保机械强度。在图5所示的第一发动机11中，第一传动件18通过螺栓安装在第一发动机11的飞轮111上，在飞轮111转动时，第一传动件18会随之转动。
一个示例性的第二传动件28的立体图如图4所示，第二传动件28包括花键轴281、齿轮282和离合器的第一传动端283，花键轴281的一端开设有花键，齿轮282套设在花键轴281上，离合器的第一传动端283固定在齿轮282远离花键的一侧。在图7所示的第一变速系统21中，第二传动件28通过轴承安装在变速箱211的外壳上，变速箱内的与花键轴281同轴设置的传动轴上设置有该离合器的第二传动端(图中未示出)。当离合器的第一传动端和第二传动端结合时，可以将花键轴与变速箱内的传动轴连接起来，实现动力传递；离合器的第一传动端和第二传动端处于分开状态时，可以将第二传动件28从变速系统上拆卸下来。需要说明的是，本公开的第二传动件28并不局限于图4所示的结构，齿轮282和离合器283的设置与变速系统的具体混动构型的设计有关，并不是第二传动件必须包括的。例如，第二传动件可以只包括花键轴，该花键轴通过联轴器与变速箱内的传动轴连接(如键链接、花键联接、销联接、紧定螺钉联接)实现动力传递，或者，第二传动件只包括花键轴和套设在花键轴上的齿轮，通过齿轮副实现与变速箱内传动轴的传动连接，等等。
请参见图5和图6，安装时，将第一变速系统21上安装的第二传动件28的花键轴插入第一发动机11上安装的第一传动件18的花键轴套，可以实现第一发动机11到第一变速系统21的动力传递。
在不同的传动包中，由于发动机的功率、扭矩等参数不同，或者变速系统的混动构型不同导致的变速比、驱动方式、负载不同等原因，发动机和变速系统之间要传递的动力是变化的。此时可以通过更换传动件组合的方式来 满足不同的动力传递要求。为了便于更换，本公开实施例不同的第一传动件的底盘和花键轴套基本相同，只是花键轴套内壁的齿数不同，而在不同发动机的飞轮上设置的用于安装第一传动件的结构(如螺孔)也可以设置为相同，任一种第一传动件可以直接装配到任一种发动机的飞轮上。相应的，不同第二传动件的花键轴的轴向长度相同，只是外花键的齿数不同。不同变速系统的变速箱用于安装第二传动件的结构可以相同。图7所示是第二变速系统安装上第二传动件后的结构图，该第二变速系统22与图5中第一发动机组成动力包时，相比图6中第一变速系统安装的第二传动件，图7中第二传动件中花键轴的齿数(如为33)与图6中第二传动件中花键轴的齿数(如为36)不同，相应的，图5中的第一发动机如果与第一变速系统组装，则可以选用花键轴套的齿数为36的第一传动件，如果与第二变速系统组装，改为将花键轴套的齿数为33的第一传动件即可。
也就是说，要实现不同动力包中发动机和变速系统之间不同的动力传递需要，只需要更换一种传动件组合即可，十分方便快捷，也节约成本。在本实施例中，不同的传动件组合中使用的花键轴的轴向长度可以相同，轴的直径也可以相同，但外花键的齿数不同，外花键的直径也可以不同，由此也可直接确定与其匹配的花键轴套内壁的齿数不同。在一个示例中，不同传动件组合下花键轴和花键轴套的齿数分别为25、27、31、33、35、37和39，外花键的齿数、直径不同时，用于传动的“齿”的结构和强度不同，可以满足于5种发动机和2种变速系统组合时不同的动力传递需要。
本公开一示例性的实施例中，将发动机和变速箱之间固定连接，以保证发动机和变速系统之间动力传递的稳定性。为此，本公开实施例中：
所述第一连接接口包括与所述发动机外壳固定连接的第一连接架，所述第一连接架上设有多个第一安装结构；
所述第二连接接口包括与所述变速箱外壳固定连接的第二连接架，所述第二连接架上设有多个第二安装结构。
作为示例性的。图5示出了第一发动机11上的第一连接架112；图8示出了第二发动机12上的第一连接架122；图6示出了第一变速系统21的变 速箱211上设置的第二连接架212和对应于飞轮的止口结构213；图7示出了第二变速系统22的变速箱221上设置的第二连接架222和对应于飞轮的止口结构223。参照上述附图，本实施例多种发动机的第一连接架均设置在发动机的飞轮的周边位置，可以固定在发动机的外壳上。本实施例多种变速系统的变速箱均设置有对应于飞轮的止口结构，且不同变速系统中的止口结构的尺寸相同。本实施例多种变速系统的第二连接架均设置在所述止口结构的周边位置，可以固定在变速箱的外壳上。止口结构的设置一方面可以辅助定位，另一方面可以承受发动机和变速箱之间的径向剪切力，以确保两者连接的可靠性。
为了方便任一发动机与任一变速系统之间的连接，任一发动机的第一连接架需要可以和任一变速系统的第二连接架对位连接。为此，本实施例中，任一发动机的多个第一安装结构与任一变速箱的多个第二安装结构的位置分别对应，通过多个第一安装结构和多个第二安装结构的对位连接，实现所述动力包中发动机和变速箱之间的固定连接。参见图5和图6所示的示例，对位连接的所述第一安装结构和第二安装结构中的一个包括螺柱501，另一个包括安装孔503，螺柱501可穿设于安装孔503并紧固；在另一示例中，对位连接的第一安装结构和第二安装结构均为安装孔，通过将螺栓穿设于所述两个安装孔并紧固，实现所述对位连接。对于本公开来说，并不要求不同发动机的多个第一安装结构在数量和位置上完全相同，及不同变速系统的多个第二安装结构在数量和位置上完全相同，只要在组装成不同的动力包时，发动机和变速系统之间有足够数量的第一安装结构和第二安装结构可以对位连接，保证两者之间可靠固定即可。
本实施例采用通用的止口尺寸和连接固定结构，使多种发动机和多种变速系统的连接接口具有通用性，通过互换安装可以快速调换不同的发动机或变速器，组装为不同的动力包。
本公开一示例性的实施例中，所述变速系统还包括第一电机，所述第一电机与所述变速箱集成在一起；在本公开另一示例性的实施例中，所述变速系统还包括第一电机和第二电机，所述第一电机和第二电机均与所述变速箱集成在一起，本实施例的变速系统充分考虑输出转矩的动力特性要求，两种 变速系统采用双电机智能多模驱动设计逻辑，利用单档或多档，离合器直接切换的逻辑，再配合双电机，使电机的高效区的运行点充分体现。
本公开又一实施例提供了一种混合动力系统的模块化组件，包括：
多种发动机，均设有第一连接接口；
多种包括变速箱的变速系统，均设有第二连接接口；
所述多种发动机和多种变速系统可构成用于混合动力系统的多种动力包，其中，任一种发动机和任一种变速箱可基于各自的第一连接接口和第二连接接口相互连接，组装为包括发动机和变速系统的一种动力包；
所述模块化组件还包括：多种动力电池，均设有第一电接口；
所述多种变速系统均包括与所述变速箱集成或连接的控制单元，多种变速系统的控制单元均设有第二电接口；
所述多种发动机、多种变速系统和多种动力电池可构成用于混合动力系统的多种动力配置，其中，任一种动力包中的控制单元和任一种动力电池可基于各自的第一电接口和第二电接口实现电连接，组装为包括发动机、变速系统和动力电池的一种动力配置。
本实施例的模块化组件不仅可以将多种发动机和多种变速系统组合为多种动力包，还可以将多种发动机、多种变速系统和多种动力电池一起组合为多种动力配置，开发M种发动机、N种变速系统和L种动力电池，可以得到M×N×L种动力配置，可以在更大程度上满足现在和将来的各种车型对动力性、经济性、排放或油耗的不同要求，通过改变一个或多个模块化组件就能满足不同的设计要求，从而缩短车型的开发周期，减少配件管理的难度，降低单个混合动力汽车的成本。
本实施例的多种发动机和多种变速系统的组合和图1所示的实施例相同，包括5种发动机和2种变速系统，除此之外，本实施例混合动力系统的模块化组件还包括多种动力电池。图2的示例中示出了3种动力电池：第一动力电池31、第二动力电池32和第三动力电池33，这3种动力电池的容量不同，可以提供不同的续航里程，也可以影响动力性，油耗，排放等指标，支持动 力架构中混合动力汽车(HEV：Hybrid Electric Vehicle)、插电混合动力汽车(P-HEV：plug in Hybrid Electric Vehicle)及后期的电动汽车(EV：Electric Vehicle)的电池匹配架构要求。在一示例中，该3种动力电池满足电池容量从0.5KWh-50KWh的设计需求，动力电池可以采用三元锂/磷酸铁锂不同化学成分的高功率密度电芯和水冷结构，做到体积小能量大的特点。
本实施例包括5种发动机、2种变速系统和3种动力电池的模块化组件，一共可以组装成10种不同的动力包和30种不同的动力配置，也即30种不同的混合动力系统。如此多种混合动力系统可以覆盖很宽的功率范围、转矩范围和电池容量范围，满足各种场景的需要。在一示例中，所述多种动力包覆盖的功率范围中，最小功率大于等于50KW小于等于100KW，最大功率大于等于150KW小于等于300KW；所述多种动力包覆盖的输出转矩范围中，最小转矩大于等于1000Nm小于等于3000Nm，最大转矩大于等于4000Nm小于等于6000Nm；所述多种动力电池覆盖的容量范围中，最小容量大于等于0.5KWh小于等于10KWh，最大容量大于等于15KWh小于等于50KWh。
如图2所示，这3种动力电池中的任一种动力电池均可以通过线束插件4与2种变速系统中的任一种变速系统的控制单元(如功率控制单元)电连接。请参见图9和图10，在本实施例中，第一电接口35和第二电接口25均设置为电插座结构，第一电接口35和第二电接口25之间的电连接通过将第一电接口35和第二电接口25分别与线束插件4两端的第一插头和第二插头插接实现。为了实现即插即用，在一个示例中，多种动力电池的第一电接口35的形状和接线端子设置相同，在不同动力配置中使用的线束插件4与第一电接口35匹配插接的第一插头41的形状和接线端子设置相同；多种变速系统中控制单元的第二电接口25的形状和接线端子设置相同，在不同动力配置中使用的线束插件4与第二电接口25匹配插接的第二插头42的形状和接线端子设置相同。也就是说，不同动力配置中使用的线束插件的两端插头是可以通用的。这些插头和插座可以遵循统一的端子标准进行设计。
本实施例在线束和接口设计上，考虑每一个接口的通用性要求，做到软件和硬件接口的端子标准化定义，可以在各模块化组件确定之后，实现对接 线线束和端子即插即用，满足目前各种架构和模块化组件之间互换。
图9示出了第一动力电池31的第一电接口35与线束插件4的第一插头41插接的结构。
图10示出了第一变速系统21中控制单元216的第二电接口25与线束插件4的第二插头42插接的结构。为了保证连接的稳固性，图示的示例中，第二插头42具有自锁拔扣421，第二插头42的接线端子也可具有自扣自检防错功能。变速箱211设置在控制单元216的下方，为了连接的稳固，变速箱211靠近控制单元216上第二电接口25的位置还设置了锁固机构2111，通过螺钉将线束插件4的第二插头42和所连接的线束固定在变速箱211或控制单元216的机壳上。只有拔开自锁拔扣411和松开螺钉，才能将脱开第二插头42和第二电接口25之间的连接，具有双保险的功能。
图11示出了第一动力电池31与第一变速系统21的控制单元216之间通过线束插件4实现电连接的示意图，图12示出了第一动力电池31与第二变速系统22的控制单元226之间通过线束插件4实现电连接的示意图。请参见该2个附图，为了方便安装，本公开实施例的多种动力电池的第一电接口均设置在动力电池组装时朝向变速系统的侧面上，多种变速系统中控制单元的第二电接口均设置在控制单元组装时朝向动力电池的侧面上。由于本实施例线束插件的两端插头可以通用而需要的弯折形状又大致相同，因此本实施例可以采用相同的线束插件实现任一种动力电池和任一种变速系统中控制单元之间的电连接，实现可跨架构即插即用。
本公开上述实施例包括发动机、变速系统和动力电池的模块化组件在即插即用的线束插件的连接下，具备通用性和互换性，可以对发动机、变速系统和动力电池等进行非常多样化的组合，满足不同架构设计逻辑，最大限度满足对混合动力系统的动力性、经济性的要求，还可以最大限度满足现在和将来的排放、油耗法规，其组装出的混合动力系统可以适用于很多车型。
具体来说，本公开实施例的模块化组件至少具有以下特点：
结构通用性，有利于采用标准化管理，缩短后期产品的开发周期和成本；组装成的混合动力系统能在各种架构的汽车中使用；
功率转矩变化，模块化组件在安装尺寸不变的情况下，通过不同的组装 方式，可以实现不同功率和转矩输出。比如一种变速系统与不同的发动机组装，可以得到多种功率和转矩配置不同的动力包，还可以配置不同的动力电池来满足不同车型对续航能力、动力性、排放、油耗等的需求；
接口即插即用，本实施例充分考虑了接口插件的互换性设计，可以采用即插即用的安装模式连接，提高模块化组件之间互换性，解决器件的通用性问题和节约安装时间，同时也可以解决生产流水线的通用性问题，使工艺装配流水线可实现同平台总装。
本公开实施例的模块化组件设计可跨架使用，根据客户需求进行不同的搭配，最大满足市场客户对混合动力系统和需求。
本公开一实施例还提供了一种混合动力系统，包括发动机、变速系统和动力电池，其中，所述发动机和变速系统由本公开任一实施例所述的模块化组件中的一种发动机和一种变速系统组装而成；或者，所述发动机、变速系统和动力电池由本公开任一实施例所述的模块化组件中的一种发动机、一种变速系统和一种动力电池组装而成。
本公开一实施例还提供了一种混合动力汽车，包括车体以及安装在车体上的混合动力系统，所述混合动力系统包括发动机、变速系统和动力电池，其中：所述发动机和变速系统具有各自独立的外壳，所述发动机设有第一连接接口，所述变速系统设有第二连接接口，所述发动机和变速系统通过第一连接接口和第二连接接口相互连接；所述发动机和变速系统在所述车体的头部沿所述车体的径向并排设置。
在本公开一示例性的实施例中，所述混合动力系统采用如本公开任一实施例所述的混合动力系统，即该混合动力系统中的发动机和变速系统由本公开任一实施例所述的模块化组件中的一种发动机和一种变速系统组装而成；或者，该混合动力系统中的发动机、变速系统和动力电池由本公开任一实施例所述的模块化组件中的一种发动机、一种变速系统和一种动力电池组装而成。
本实施例的发动机和变速器在组装时，采用径向延展方式连接，通过设计通用的安装连接方式，达到各种模块化组件之间可互装互换的特点，通过改变单个模块化组件(如发动机或变速器)，可以最大限度地在同架构下满足不同组合的设计要求，做到在同一辆车也可以有不同的动力和油耗的驾驶体验，在一示例中，通过5种发动机模块和2种变速箱模块组成10种动力包，覆盖了70KW-180KW,输出转矩2000Nm-5000Nm的动力输出能力。
在本公开一示例性的实施例中，所述动力电池安装在所述车体底部的前桥和后桥之间的位置。本实施例动力电池(也可称为电池包)安装在车体底部空间，对低容量的动力电池，可以利用中控道空间。由于本实施例的发动机和变速系统采用径向延展方式连接，在不同架构下，动力电池的轴向安装尺寸都可以相同，实现跨架构同模块的设计目标。对于中高容量的动力电池，为了充分利用车架底部尺寸，动力电池可以采用超薄设计(如图2中的第三动力电池33)，嵌入安装的方式。在不同的架构下，轴向底板安装尺寸不改变，来满足动力电池的嵌入安装，也可以做到使用不同动力配置时，满足同车型的不同动力性和油耗的要求。
如图13所示，第一发动机11和第一变速系统21在车体的头部沿车体的径向并排设置，相互连接组装为动力包。第一动力电池31安装在车体底部的前桥和后桥之间的位置，通过线束插件4与变速系统21中的控制单元电连接。其他动力配置下的发动机和变速系统也是在车体的头部沿车体的径向并排设置，动力电池也是安装在车体底部的前桥和后桥之间的位置，不再一一示出。
需要说明的是，本公开实施例的混合动力汽车，发动机和变速系统在车体头部沿所述车体的径向并排设置、动力电池安装在车体底部的前桥和后桥之间，这种结构的混合动力汽车的混合动力系统并不局限于由模块化组件组装而言，也可以是非模块化的发动机、变速系统和动力电池组成的混合动力系统。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
