具体实施方式：
1.人员正向行走控车方式
在车前部设置传统自行车座位，结构相似，车头改低改小(图2，图3：1；3)，实现人员正向骑行控车。车座的仰俯，升降，前后均可调。能前后移动的滑轨采用扁钢管，上焊扁钢板，(图2：4图3：4.1；4.2)钢板二侧宽边压在滑槽内，滑槽用前后二组左右各二个小压板结构，焊在车座后第一第三车框架下方(图3：4.3)。第三框架上的另一组压板被电池遮住【图3：7.1(被滑轨遮挡)：7.2】。滑轨左右限位，前后可滑动调整，再用圆销钉插孔中定位(图2：5.3；图3：5.3)。圆销钉底部有横孔，穿开口销(图3：6)。控制电线总线从扁管中穿过，用航空插头插座与电器箱联结(图3：8.3)。电机，电池及图2中5.41&5.42的电线，也用几个航空插头插座与电箱连接(图中未标出)。销售运输中，车座部件可整体抽出另外装箱。
2.助人抬升力方案：
本发明将车下部按设计最佳值加长，车下部小轮与大轮胎同时着地时，车架与地面倾斜角度约为40°±5°(图3)，大于常规楼梯坡度。该爬楼车上升时，旋转腿端部搭在楼梯台阶上，成为临时中心支点，与整车重心，人员重心，三者形成跷跷板原理和效果，整车重心偏后，对人员有30kg抬升力。抬升力大小可在使用前预先设定。当车上爬时，人员顺势单腿用力，跨上一级台阶，腿力可减轻约30kg，并保持控车能力。抬升力设定得太大，人会飘，不稳定(见本说明书7)。
3.助人水平方向推力方式
本发明采用“有水平推力的电动爬楼车旋转腿”(图8)，其滚轮不能滚动。选用适当软硬度的胶质滚轮，扩大与地面接触面积，可产生适当抓地力。当旋转腿向后转动阶段，整车便有向前推力。可再次减轻使用者体力。
4.控制开关及用车方法：
车座下面，装一块翻边底板(图2：2)，底板前端焊一段方管(图2：2.1，图3：2.1)方管中部横穿一根实心铝棒，做前把手(图2：2.2)，可左右灵活滑动，拐弯时可滑动让位。方管前面，上部左边装一只黄色旋钮，管慢速-中速无级调速功能(图2：2.13；图9：3)。方管上部右边，装一只绿色旋钮，管中速-快速无级调速功能(图2：2.14；图9：4)，方管中部，装一只黄色按钮开关，管慢速下楼功能(图2：2.15；图3：2.15；图9：7)，由左上角2.13黄色旋钮实现下楼的无级调速。方管前面下部，装一只橡皮防撞垫(图2；图3：2.16；图9：9)。方管上顶部装一块小平板(图2：2.17；图3：2.17；图9：1)。小平板左边，装一只黄色按钮开关(图2：2.11；图9：5)，管整车启停。右边装一只绿色按钮开关(图2：2.12； 图9：6)，管快慢速功能转换。小平板中上部装一只带红色电源指示灯带自锁按钮型安全开关(图2：2.10；图9：11)，关闭时停止一切操作功能。如要开车，首先打开安全开关。但是不能先按小平台绿色快慢速功能开关(设计成无效)，只能先按小平台黄色启停开关，就能慢速启动。启动后，随时可按下绿色快慢速转换开关，立刻转快速。如再松开绿色按钮开关，1秒后又转慢速，可如此反复。慢速调速可在开车状态下调整，快速调速可在慢速或停车状态下调整，因为只有在此状态下右手可以另做动作。每层楼梯上下二头，用慢速上爬，中间可快速。所有黄色绿色按钮开关均无自锁功能。
5.正常停车方法：
在快速功能下要停车，应该先改为慢速功能，即先松开右边绿色按钮开关(图2：2.12；图9：6)。约1～2秒后，再松开左边黄色启停按钮开关(图2：2.11；图9：5)，之后由接近开关控制断电，停车，涡轮箱阻尼刹车。旋转腿停在预设角度位置上，不使重启有麻烦。在慢速功能下要停车，松掉图2中2.11黄色启停开关即可，后面程序如上所述。
6.紧急停车方法：
在快速爬楼时，如有突发情况，可紧急停车，而且无需人员操作，由设计的程序自动控制。具体介绍如下：突发情况是人快速爬楼时绊脚或者滑倒，这时候人体条件反射，本能地双手立刻脱离开关，前伸撑地自我保护。本设计只要在快速功能下，二只按钮开关(图2：2.11；2.12图9：5；6)同时松开，便能立刻断电停机，阻尼刹车。这时人员前扑撑地，双腿还夹着车头及左右前把手，车头方向不会偏，加上阻尼刹车，抓地力固位，大轮腾空，可使事故最小化。(绊脚或滑到一般发生在车上升阶段，此时大轮腾空)。快速时如需人为紧急停车，不松绿色按钮开关，仅松开黄色按钮开关，也能实 现紧急停车。
7.抬升力设定方法：
这是紧急停车功能的人为需要使用方法：
装货时，将车靠楼梯，下部预先搁在角铁上，再放在家用体重计上(图3：01；011)，人站楼梯上，操作如下：第一步：①按黄色按钮开关启动慢速上爬(图2：2.11)。②立刻按绿色按钮开关，转快速功能(图2：2.12；图9：6)。③当大轮胎离地大半个台阶，立刻松开二只开关，或单独松开黄色启停开关，实现紧急停车。④立刻读数体重计。所示重量乘工厂指定系数便是抬升力大小(图3：01)。更换图3中1.1-1.4各货箱位置或箱内货物，可改变体重计读数，使达到30kg左右。如大轮胎运动较快来不及读数，可由另一人读数。如来不及上述操作，可调慢快速旋钮的车速(图2：2.14图9：4)。第二步，大轮着地，体重计读数调整在1～5kg，这样可使运动中车头不下垂。第一第二步互有影响，重复调整几次即可都达标。
8.座位调整
①按图3，设定完抬升力后，可马上调整自行车座仰俯；车座高低仰俯由使用者试坐，使车框与楼梯大致平行或上翘一点即可，调整车座前后应以靠后为好。
②按图6，乘员的座位架用绳索先固定在合适位置上，座位板是摆动型的(图6：1、2、3.1、3.2)，乘员须随车的角度变化，随时移动身体，并用脚配合，保持平衡。
9.下楼操作方法：
如上楼作业完成，撤离首选恢复正常的电梯，其次选择自行下楼功能。方法 如下：先将电器箱上专用开关扳至“下楼”功能(图2：8.2)，操作人员双手握住前把手(图2：2.2)，大拇指按住下楼用的黄色按钮开关(图2：2.15图3：2.15图9：7)，便能慢速下楼。车速由方管上方黄色旋钮调节(图2：2.13；图9：3)。这时人员不骑车，扶车下楼。
10人员上下车方法：
人员若从车左边上车，先用右手掌心向前握住车座后把手，防撞垫压在地面上(图3：3.3)。左腿站稳，右腿从车头前跨至车右边落地，并骑上车座，再双手握车前左右把手，提起车头，便可开车爬楼。人员如从右边上车，同理。下车反程序操作。
11.小半径转弯方法：
楼梯拐弯处平台宽度大于1.1m，人可骑车直上顶楼，无需下车。该处宽度小于1.1m大于0.9m时，人要下车操控拐弯。方法如下：先提前一级台阶慢速停车在台阶上，人左边下车后，右手握车座后面第一根框架底下方管拉手(图2：5.51)，左手握车座升降管(图2：3)，右手大拇指短促点动一次方管拉手上黄色慢速上爬按钮开关(图2：5.1)，使车爬上最后一级台阶并关车，稍往前拖，抬车头至小轮着地仅稍压地面便可转弯。人右边下车同理操作，双手作用对换。
当拐弯处宽度小于0.9m，本车不能使用。
12.后续使用或练习中，在确保人员控车能力前提下，可尽量提高助人抬升力。
13.控制总线(图2：8.31)，左右拐弯开关电线(装在左右框架管内，电箱前穿出管外)(图2：5.41，5.42)，锂电池电线(图中未标出)，电机电线(图 中未标出)，可用多种类型插头插座与电器箱连接(图3：8.3)。多个插头插座图中未标出。
14.锂电池：因车座滑轨居中，锂电池分成左右相同二组，再串联或并联使用。充电插座和锂电池直流输出插座在电器箱左侧(图中反面未标出)。
15.此车平地也能行走，不能开机，可推可拉，四轮或两轮都能使用。平地拐弯大轮为主，小轮稍碰或不碰地。
16.车架长×宽×高约1200×550×380(mm)
