【具体实施方式】
下面将结合附图及多个实施例对健身发电车作进一步的详细说明，应当理解的是，在未做例外说明得情况下，下列多个实施例的特征也可有益的相互结合。
请参阅图 1 ，实施例一的健身发电车 100 包括脚踏车健身器 10 、发电机 20 、链条 30 、蓄电池 40 和逆变器 50 。
请同时参阅图 2 ，脚踏车健身器 10 包括主车架 11 和主动链轮 13 。主车架 11 包括基座 111 和固定设于该基座 111 上的车梁 113 和车座 115 。车梁 113 大致呈 L 型，其前端形成供使用者握持的把手 117 。主动链轮 13 枢接于车梁 113 的底部。主动链轮 13 上还设有脚踏板 131 。使用者可以坐在车座 115 蹬踏脚踏板 131 ，以带动主动链轮 13 旋转。
主车架 11 还包括设于基座 111 和车梁 113 之间的两个支撑板 119 。每一支撑板 119 大致为 U 型，其两端可通过焊接等方式分别固定在基座 111 和车梁 113 上。请一并参阅图 3 ，每一支撑板 119 中部开设有两个固定孔 118 。支撑板 119 的作用是可以增加主车架 11 的平稳性，防止使用者在做健身运动时主车架 11 发生晃动。发电机 20 活动设于该两个支撑板 119 上。
请一并参阅图 4 ，发电机 20 包括转轴 201 和固定在转轴 201 上的从动链轮 203 。发电机 20 优选为稀土永磁无铁芯发电机。
健身发电车 100 还包括两个固定板 21 。该两个固定板 21 通过多个螺钉 ( 未标示 ) 固定在发电机 20 的两侧。请一并参阅图 5 ，优选的，每一固定板 21 上开设有两个大致平行的第一定位槽 211 。每一第一定位槽 211 开设于固定板 21 的边缘，并朝远离主动链轮 13 的方向延伸。
优选的，健身发电车 100 还包括四个第一锁紧件 40 。每一第一锁紧件 40 穿过支撑板 119 的其中一个固定孔 118 ，并锁合于固定板 21 的一个第一定位槽 211 内。
组装时，首先将两个支撑板 119 焊接在基座 111 和车梁 113 之间，然后将两个固定板 21 通过多个螺钉固定在发电机 20 的两侧，再通过四个第一锁紧件 40 将两个固定板 21 连同发电机 20 一起锁合于两个支撑板 119 上，最后通过链条 30 连接脚踏车健身器 10 的主动链轮 13 和发电机 20 的从动链轮 203 ，并通过导线将发电机 20 和蓄电池 40 及逆变器 50 电连接。健身发电车 100 组装完毕。
使用时，使用者蹬踏脚踏板 131 时可带动主动链轮 13 旋转，并通过链条 30 带动发电机 20 的从动链轮 203 旋转，从而使得发电机 20 产生电能。发电机 20 会根据从动链轮 203 转速的快慢而产生不同电压的电流。该电流对蓄电池 40 充电。蓄电池 40 储存的电能经过逆变器 50 的调节后，变成标准的 220V ， 50Hz 的交流电，可用于室内照明或家用电器。
使用者还可根据个人体力对健身强度进行调节。本实施例中，可通过调节第一锁紧件 40 在第一定位槽 211 内滑动的位置，以调节发动机 20 的从动链轮 203 与脚踏车健身器 10 的主动链轮 13 之间的距离，从而调节链条 30 的松紧。
上述健身发电车 100 结构简单，操作方便，发电过程安全环保，不仅锻炼的使用者的身体，而且可将锻炼时产生的能量储存起来以后需要时使用，在一定程度上起到了节能环保的作用。
可以理解，第一定位槽 211 也可开设在支撑板 119 上，此时第一锁紧件 40 对应设于固定板 21 上。第一锁紧件 40 的数量也不限于四个。
请参阅图 6 ，实施例二的健身发电车 200 与实施例一的健身发电车 100 大致相同，其不同之处在于：健身发电车 200 还包括飞轮 60 、电机支架 70 、两个电机座 80 和四个第二锁紧件 90 。
请一并参阅图 7 ，飞轮 60 设于发电机 20 的转轴（图未示）上，以增大转轴的惯性。
请参阅图 8 ，电机支架 70 包括两个支撑腿 71 和连接两个支撑腿 71 的支撑块 73 。两个支撑腿 71 可通过焊接等方式固定设于基座 111 上。支撑块 73 上开设有对应四个第二锁紧件 90 的四个通孔 731 。发电机 20 活动设于电机支架 70 上。
两个电机座 80 是用于支撑发电机 20 。请参阅图 9 ，每一电机座 80 对应于第二锁紧件 90 的位置开设有一个长条形的第二定位槽 81 ，其延伸方向与主动链轮相对。
组装时，首先将电机支架 70 焊接在基座 111 上，并将两个电机座 80 通过螺钉固定在带有飞轮 60 的发电机 20 底部，然后通过四个第二锁紧件 90 将每一电机座 80 锁合于电机支架 70 ，其他组装过程与实施例一类似，在此不再赘述。
与实施例一相似的，当使用者需要调节健身强度时，可通过调节第二锁紧件 90 在第二定位槽 81 内滑动的位置，以调节发动机 20 的从动链轮 203 与脚踏车健身器 10 的主动链轮 13 之间的距离，从而调节链条 30 的松紧。
可以理解，第二定位槽 81 也可开设在电机支架 70 上，此时第二锁紧件 90 对应设于电机座 80 上。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
