背景技术
近年来，为了提高电动车的续航里程，市场上出现了一种增程式电动车，它是在电动车的动力系统中增加了一套由燃油或燃气发动机带动的发电机系统，当电动车的电池电量消耗到一定程度时，该发动机启动发电并对电池充电，以延续行驶里程。
例如，中国专利申请号为ZL201820835662.4的专利，公开了一种对置双活塞式内燃永磁直线发电机，包括第一缸体、第一火花塞、第一活塞连杆、第二缸体、动支架、磁环、线圈、铁芯和铁芯支撑架。上述专利中的一种对置双活塞式内燃永磁直线发电机存在以下不足：该专利中，在通过使用第一复位弹簧和第二复位弹簧进行复位时，因第一复位弹簧和第二复位弹簧属于机械弹簧机构，弹簧是个蓄能器，反应频率慢，且易疲劳老化，使用效果差，故需要另行设计并采用反应频率更快的返程复位机构。

以下结合说明书附图，对本发明的具体实施方式做进一步详细说明。
实施例一：根据说明书附图1,2所示，具有返程复位装置的相对活塞式内燃永磁直线发电机7，包括固定梁1，用于提供动力的第一相对活塞式内燃机2和第二相对活塞式内燃机3，第一相对活塞式内燃机2和第二相对活塞式内燃机3设置有用于进出气的进气门和排气门，第一相对活塞式内燃机2设置有用于点火的第一火花塞201，第二相对活塞式内燃机3设置有用于点火的第二火花塞301，第一相对活塞式内燃机2内设置有第一活塞202，第二相对活塞式内燃机3内设置有第二活塞302，第一相对活塞式内燃机2的两侧边设置有用于输出动力的第一活塞杆203，第二相对活塞式内燃机3的两侧边设置有用于输出动力的第二活塞杆303。上述为现有技术，在此不再一一赘述。第一相对活塞式内燃机2和第二相对活塞式内燃机3内的燃料可以是柴油、甲醇、汽油和天然气，第一相对活塞式内燃机2和第二相对活塞式内燃机3的压缩比从11到25不等，第一相对活塞式内燃机2和第二相对活塞式内燃机3的材料为铝合金，第一活塞杆203和第二活塞杆303均穿过返程复位机构6连接到直线发电机7。第一相对活塞式内燃机2和第二相对活塞式内燃机3关于固定梁1长度方向对称设置，第一相对活塞式内燃机2和第二相对活塞式内燃机3位于固定梁1长度方向的中心位置。固定梁1可以选用但不限于工字钢，固定梁1的两端通过螺栓固定在外箱体的内壁上。第一相对活塞式内燃机2和第二相对活塞式内燃机3通过第一固定座4与固定梁1固定连接，第一固定座4呈截面为等腰梯形的结构，固定座与固定梁1采用螺栓固定，第一固定座4与第一相对活塞式内燃机2和第二相对活塞式内燃机3均采用焊接的连接方式。固定梁1上固定连接有保证第一相对活塞式内燃机2 和第二相对活塞式内燃机3始终保持直线输出的直线轴承5，直线轴承5为现有技术，固定梁1上螺栓固定有卡接座，卡接座呈空心四棱柱结构，卡接座远离固定梁1的一端设置有用于直线轴承5卡接的卡接孔，形成对直线轴承5的固定结构。用于保持第一相对活塞式内燃机2的两个第一活塞杆203呈直线运动的直线轴承5有四个，用于保持第二相对活塞式内燃机3的两个第二活塞杆303呈直线运动的直线轴承5也有四个。第一相对活塞式内燃机2和第二相对活塞式内燃机3的两侧边分别设置有与其连接且固定在固定梁1上的返程复位机构6，形成第一相对活塞式内燃机2和第二相对活塞式内燃机3在两返程复位机构6的配合下做到在设定时间内间隔输出的结构。返程复位机构6包括固定在第一活塞杆203和第二活塞杆303上的齿条601a，齿条601a与第一活塞杆203和第二活塞杆303的固定方式包括但不限于焊接。固定梁1上设置有与两齿条601a啮合的扇形齿轮602a，由于返程复位机构6的行程的一定的，并不需要采用完整的圆形齿轮进行驱动，扇形齿轮602a的齿数的多少根据返程复位机构6的行程进行适应性的加工。固定梁1上设置有用于扇形齿轮602a旋转用的旋转杆603a，旋转杆603a与固定梁1的连接方式包括但不限于焊接，扇形齿轮602a中心位置设置有圆孔，圆孔贯穿扇形齿轮602a厚度方向，旋转杆603a上卡接有与圆孔过盈配合的第一轴承604a，第一轴承604a为深沟球轴承，形成第一活塞杆203向远离第一相对活塞式内燃机2的方向运动时，返程复位机构6带动第二活塞杆303向靠近第二相对活塞式内燃机3的方向运动的结构。返程复位结构远离第一相对活塞式内燃机2和第二相对活塞式内燃机3的一端设置有用于发电的直线发电机7，直线发电机7通过第二固定座8与固定梁1固定连接，第二固定座8采用螺栓固定到固定梁1上，第二固定座8与直线发电机7的外壁采用焊接。直线发动机关于固定梁1长度方向对称设置，形成直线发电机7在第一相对活塞式内燃机2和第二相对活塞式内燃机3的带动下，结合返程复位机构6持续发电的结构。
在一实施例中，根据附图1，2所示，直线发电机7包括动子与定子，动子包括位于第一活塞杆203和第二活塞杆303圆周外表面设置绕其一周的磁环701，磁环701有多个且间隔均匀排列，各相邻磁环701中间均设置有用于隔绝 磁力的隔磁环702，直线发电机7还包括与固定梁1固定连接的线圈703，形成第一活塞杆203和第二活塞杆303带动磁环701移动时穿过线圈703做切割磁感线运动进而发电的结构。第一活塞杆203和第二活塞杆303圆周外表面胶接有隔热环704，磁环701与隔磁环702均胶接到隔热环704的外表面，能够有效的防止磁铁高温退磁。动子包括线圈，磁环701与线圈703之间存在间隙，线圈703有多个且多个线圈703均首尾相互连接，构成一个统一的集线圈703，使每个线圈703上所产生的感应电动势相互叠加在一起，向外输送电流。定子线圈703通常是将导线绕制在一定形状的铁芯上。第一活塞杆203带动齿条601a移动，齿条601a带动扇形齿轮602a通过旋转杆603a在固定梁1上转动，并带动第二活塞杆303上的齿条601a运动，扇形齿轮602a通过回旋力加速第二活塞杆303的移动。在第一活塞杆203返程运动时启动第二相对活塞式内燃机3，进而加速第一相对活塞式内燃机2的返程运动，第一相对活塞式内燃机2与第二相对活塞式内燃机3的做工运动与返程运动相互配合，加上第一活塞杆203与第二活塞杆303带动磁环701移动，磁环701切割线圈703产生电力。本系统在启动时，可将直线发动机当启动电机用。此时的操作是：通过电池先给发电机定子线圈703供电，有第一活塞杆203和磁环701组成的动子就会带动第一相对活塞式内燃机2运动起来。此时停止供电，转换为进气供甲醇发动机系统运行。
第一相对活塞式内燃机2与第二相对活塞式内燃机3以固定梁1长度方向为中心相互平行且对称设置，第一相对活塞式内燃机2和第二相对活塞式内燃机3的两端一共设置四个永磁直线发电机7且其配合使用，共同固定在固定梁1的两端。第一相对活塞式内燃机2的两个第一活塞杆203的端部对称安装有直线发电机7的动子，直线发电机的定子螺栓固定在固定梁上。当第一相对活塞式内燃机2的中央燃烧室喷进燃料点火燃烧后，其高压气体就推动两个第一活塞杆203运动，两个动子永磁体产生的磁力线就被不动的定子线圈所切割而发电，第一相对活塞式内燃机2和第二相对活塞式内燃机3，通过返程复位机构来实现一相对活塞式内燃机点火时推动活塞运动的动力转化为另一相对活塞式内燃机的两个活塞复位的返程力，反之亦然。
两相对式活塞内燃机按照设定周期轮流交替点火，通过返程复位机构实现一相对式活塞内燃机推动活塞杆的动力转化为另一相对式活塞内燃机活塞复位的返程力，
实施例二
结合一实施例，根据附图3，2所示，固定梁1上固定连接有保证第一相对活塞式内燃机2和第二相对活塞式内燃机3始终保持直线输出的直线轴承5，直线轴承5为现有技术，固定梁1上螺栓固定有卡接座，卡接座呈空心四棱柱结构，卡接座远离固定梁1的一端设置有用于直线轴承5卡接的卡接孔，形成对直线轴承5的固定结构。用于保持第一相对活塞式内燃机2的两个第一活塞杆203呈直线运动的直线轴承5有四个，用于保持第二相对活塞式内燃机3的两个第二活塞杆303呈直线运动的直线轴承5也有四个。返程复位机构6包括旋转架601b，旋转架601b截面呈菱形，旋转架601b上沿其长度方向的中线上设置有长槽602b，长槽602b贯穿旋转架601b的厚度方向，长槽602b有两个且关于旋转架601b中心呈中心对称设置。返程复位机构6还包括固定在第一活塞杆203和第二活塞杆303上与旋转架601b配合使用的固定柱603b，第一活塞杆203和第二活塞杆303上螺栓固定有固定柱603b，固定柱603b呈圆柱结构且可在长槽602b内滑动。固定梁1上设置有用于旋转架601b旋转用的转动杆605b，转动杆605b与固定梁1焊接连接，旋转架601b中心位置设置有贯穿其厚度方向的旋转孔，转动杆605b上卡接有与旋转架601b中心位置旋转孔过盈配合的第二轴承604b，形成第一活塞杆203向远离第一相对活塞式内燃机2的方向运动时，第一活塞杆203上的固定柱603b带动旋转架601b转动，进而带动第二活塞杆303向靠近第二相对活塞式内燃机3的方向运动的结构。
实施例三
结合一实施例，根据附图4，2所示，采用液压作为返程复位机构，由于液压反应时间慢，所以采用液压作为返程复位机构只适用于大型的发电设备，返程复位机构6包括固定在第一活塞杆203上的第三活塞601c和固定在第二活塞杆303上的第四活塞602c，返程复位机构6还包括U型管603C，U型管603C固定 在固定梁1的两端，固定梁1上设置有用于U型管603C穿过的通孔，用于U型管603C在固定梁1上的放置，U型管603C与固定梁1通过螺栓固定。第一活塞杆203和第二活塞杆303贯穿U型管603C的两端且第三活塞601c和第四活塞602c分别置于U型管603C的两端，U型管603C内充满液压油604c，形成第一活塞杆203带动第三活塞601c向远离第一相对活塞式内燃机2的方向运动时，U型管603C内的液压油604c推动第四活塞602c带动第二活塞杆303向靠近第二相对活塞式内燃机3的方向运动的结构。
本发明返程复位机构的设置，更好的为第一活塞杆和第二活塞杆运动提供适应性的动力，且返程复位机构采用复合机械结构，避免了由于多次往复运动造成的设备老化，提高使用寿命；固定梁上下两边的第一相对活塞式内燃机和第二相对活塞式内燃机按照设定时间轮流交替点火，再加上与其相互配合使用的返程复位机构，提高了第一活塞杆和第二活塞杆的输出频率，在直线轴承的作用下，确保其做到精准直线输出，提高第一相对活塞式内燃机和第二相对活塞式内燃机的点火频率，即提高了直线发电机的磁环作直线运动的速度，使其加快切割线圈，进而提高直线发电机的发电效率；第一活塞杆和第二活塞杆互为发电机动子运动的动力，又互为返程复位的推力，第一相对活塞式内燃机和第二相对活塞式内燃机按照设定时间轮流交替点火，推动第一活塞杆和第二活塞杆持续往复运动，为第一活塞杆和第二活塞杆的运动提供辅助动力，合理利用能源，提高发电效率。
以上通过具体实施方式和实施例对本发明进行了详细的说明，但这些并非构成对本发明的限制。在不脱离本发明原理的情况下，本领域的技术人员还可做出许多变形和改进，这些也应视为本发明的保护范围。
