固定轴和螺母，前面的安装在前轮轴上；后面的可以安装在后轮轴上，也可以按在后下叉或后上叉。

 本发明的最佳实施方式
下面将结合图1到图19对本发明进行详细说明，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例 1：
一种增加滑行轮的折叠自行车，其特征在于位于折叠部位增加一个滑行轮。
本实施例进一步设置为：所述滑行轮，为万向轮，轮向下，轮座固定在自行车折叠部位的下面。
工作原理：两个轮折叠在一起的基础上，再增加一个辅助轮，三个能滚动的支撑点，就可以使折叠车立起放、推起或拉起走了。
实施例 2：
位于折叠部位增加一个滑行轮，其特征还在于包括：后叉1、折叠万向轮固定架2、弹簧3、转动杆4、固定叉5、万向轮6、脚踏臂顶端7，所组成的装置。
本实施例进一步设置为：所述后叉1：位于自行车后轴，通过后轴和螺丝固定自行车后轮，在固定脚架一边的后叉1上，有折叠万向轮固定架2固定有一万向轮6；所述折叠万向轮固定架2：位于自行车脚架侧的后叉1末端，紧邻自行车脚架，为一环抱式紧固结构，通过螺丝固定在后叉上，弹簧3一端的挂钩钩在该结构中间位置的挂钩上，在其顶端有一销孔，转动杆4通过销钉固定在其上方，且转动杆4可以绕其转动一定角度；所述弹簧3：类似于自行车脚架弹簧，弹簧一端挂在折叠万向轮固定架2上，另一端挂在转动杆4上的挂钩上，便于折叠万向轮结构在折叠时自动复位；所述转动杆4：通过固定销固定在折叠万向轮固定架2上，并可绕折叠万向轮固定架2转动一定角度，转动杆在往下转动时，其末端的固定叉5将向斜下方运动，且固定叉5最终将卡住位于最低点的脚踏臂顶端7。在转动杆上方还有一挂钩挂住弹簧3，便于折叠结构的自动复位，在其另一端固定有万向轮6和“U”字型固定叉5，万向轮6在折叠时的位置保证不会干扰自行车脚踏臂结构的使用；所述固定叉5：形状为字母U字形，位于转动杆4末端，其下方固定有万向轮6，固定叉5开口宽度与脚踏臂顶端宽度相匹配，且固定叉5可卡住位于最低点脚踏臂顶端，便于折叠后的自行车滑行；所述万向轮6：位于固定叉5下方，同一般的万向轮6结构相似，万向轮6折叠时不会对自行车工作的脚踏有干扰；所述脚踏臂顶端7：自行车脚踏臂和脚踏轴相连部位。
工作原理：自行车折叠后，前后轮并排在一起且同轴心，此时向下转动转动杆4，待万向轮6接触到地面时稳住万向轮6，用另一只手转动同侧的脚踏至最低点，固定叉5卡住脚踏臂顶端7，使得被弹簧3拉住的转动杆4不会往回转动，现在二者紧密的结合在一起，万向轮6和折叠后自行车的两轮形成三个支撑点，共同支撑自行车，现在自行车使用者就踩在卡住的脚踏上，滑动折叠后的自行车；而要打开自行车使用时，只需转动脚踏臂，使得脚踏臂顶端7与固定叉5分离开，转动杆4在弹簧3作用下自动折叠复位，折叠后的万向轮6位置将不会对工作中的脚踏臂产生干扰，需再次滑行时，仅需重复万向轮的打开动作。
实施例 3：
位于折叠部位增加一个滑行轮，在折叠车没有后下叉也能够滑行的折叠自行车，其特征在于包括：万向轮、旋转固定叉、万向轮柱、万向轮筒、脚踏臂顶端组成的装置。
本实施例进一步设置为：所述万向轮：固定于旋转固定叉下方，万向轮折叠时不会对自行车工作的脚踏有干扰；所述旋转固定叉：形状为字母U字形，旁边固定万向轮柱，其下方固定万向轮，固定叉开口宽度与脚踏臂顶端宽度相匹配，且固定叉可卡住位于最低点脚踏臂顶端，便于折叠后自行车的滑行；所述万向轮柱，类似上述能够滑行的折叠自行车的转动杆，呈柱状，位于万向轮筒内，可在万向轮筒内上下移动，在其下端固定有旋转固定叉；所述万向轮筒，竖立固定在坐凳下的外钢管旁边，万向轮筒内容纳万向轮柱；所述脚踏臂顶端：自行车脚踏臂和脚踏轴相连部位。
工作原理：用图1来做说明，一个带棍的万向轮，象图1中的万向轮6、旋转固定叉5、万向轮柱4结构，可在万向轮筒里移动：移动到地面，是滑行状态，此时当旋转固定叉5 卡住脚踏臂顶端7后，人就可以踩上脚踏滑起走；移动到上面，是收起的状态。
实施例 4：
一种增加滑行轮的折叠自行车，其特征在于增加包括：固定轴1、卡箍2、固定座3、卡箍滑块4、卡锁结构5、螺母6组成的钳卡式两轮中轴固定装置。
本实施例进一步设置为：所述固定轴即自行车后轴，与普通后轴比较，固定轴圆周上方加工有一环形卡箍，卡箍的大小形状与卡箍滑块上的凹槽大小形状相匹配，卡箍使得固定轴插入固定座后卡箍滑块卡住卡箍，从而使自行车前后轴相互固定卡紧，所述卡箍位于固定轴前端，为一圆环环抱在固定轴前端，其大小形状与卡箍滑块上的凹槽大小形状相匹配，便于固定轴插入固定座后卡箍滑块可卡住卡箍，所述固定座位于自行车前轴上，在固定座下方通过螺母旋在自行车前轴上，在其上方有通过卡锁结构连接着的卡箍滑块，且卡箍滑块被触碰一次就会滑入固定座并锁紧固定轴，而再触碰一次卡箍滑块，卡箍滑块就会被连着的卡锁结构弹出固定座，因而卡箍滑块就不在束缚固定轴，所述卡箍滑块位于固定座上，卡锁结构是连接卡箍滑块和固定座的纽带，当固定轴插入固定座内，固定轴首次触碰卡箍滑块，卡箍滑块滑入固定座并卡住固定轴，这时折叠后的自行车两轮就固定在一起了，若要两轮分离，需向其中一轮施加一个往里靠紧的力，卡箍滑块受到二次触碰，卡箍滑块背后的卡锁结构将卡箍滑块推出固定座，两轮分离，所述卡锁结构同时连接着卡箍滑块和固定座，可使卡箍滑块固定在固定座内或使得卡箍滑块被弹出固定座,卡锁结构使得卡箍滑块首次触碰固定座时，固定座卡住卡箍滑块，此时卡箍滑块再次触碰固定座时，固定座将卡箍滑块推出，所述螺母位于固定座下方，其大小与自行车前轴相匹配，螺母旋紧在自行车前轴上，固定座也就固定在自行车前轴上了。
工作原理：固定座3通过其下方的螺母6旋紧在自行车前轮轴上，而固定轴1即自行车后轴末端圆周上固定有一圈卡箍2，自行车通过车架上的折叠结构折叠起来，折叠后的自行车前后轮的中心正好对接在一起，这时位于前轮轴上的固定座3和后轮上的固定轴1也正好对在一起，二者即将要接触时施加一个外力，使得固定轴1前端首次触碰位于固定座3上的卡箍滑块4，卡箍滑块4滑入固定座3并卡住固定轴1上的卡箍2，这时折叠后的自行车两轮就固定在一起了，由于固定后的两轮并排在一起，所以可以推行折叠后的自行车；而要打开自行车使用时，需向其中一轮施加一个往里靠紧的力，卡箍滑块4受到二次触碰，卡箍滑块4背后的卡锁结构5将卡箍滑块4推出固定座3，两轮分离，自行车打开完成可骑行。
实施例 5：

本实施例进一步设置为：所述卡锁装置，安装在横把里，由弹簧1、挡板10、带球面的卡锁2、解锁凸起3、解锁凸起槽9组成；所述弹簧1，安装在挡板10和带球面的卡锁2之间；所述挡板10，固定在横把里，其顶部是车首竖杆圆柱形端4；所述带球面的卡锁2，呈带球面的圆柱体，圆柱上面有解锁凸起，球面对应车首竖杆锁槽6；所述解锁凸起3，固定在带球面的卡锁2上，穿过解锁凸起9槽；所述解锁凸起槽9，位于横把上面的贯穿槽，呈长条形，宽与解锁凸起3对应，长度和解锁行程相对应；所述车首竖杆5，呈圆筒形，顶部是车首竖杆圆柱形端4；所述车首竖杆圆柱形端4，位于车首竖杆5顶端，和横把圆形孔8相对应；所述车首竖杆锁槽6，形状和带球面的卡锁2相对应，位于车首竖杆圆柱形端4里，上下左右个一个；所述横把，平行安装在车首竖杆5上的圆管；所述横把圆形孔8，形状和车首竖杆圆柱形端4的多边形相对应。
工作原理：在锁住状态时，弹簧充分顶住带球面的卡锁，让带球面的卡锁2卡在车首竖杆锁槽6里；转动横把时，使用者用手扣住解锁凸起9，朝弹簧1方向扳动，让带球面的卡锁2脱离车首竖杆锁槽6，转动横把，就把横把从横向变成竖向，利于折叠得更薄；竖向横把变成横向横把时，使用者用手扣住竖向横把解锁凸起9，朝弹簧1方向扳动，让带球面的卡锁2脱离车首竖杆锁槽6，将横把转回到横向正常位置，分开手，让带球面的卡锁2卡在车首竖杆锁槽6里，就可以了。
实施例 6：
根据一种增加滑行轮的折叠自行车可转动90度的方向横把装置，当自行车折叠后，方向横把再转动90度，一方面进一步减小了折叠后自行车的厚度，另一方面可以作为将折叠后的自行车推起走、拉起走的把手，更想不到的是，当方向横把的长度不大于车圈直径的120%时，还可以作为折叠车将折叠部位立起停放的第三个支点。
实施例 7：

实施例 10：
一种增加滑行轮的折叠自行车，其特征在于更换单管式前车架为包括：车架固定部分1、伸缩杆2、固定销孔3、车架伸缩部分4、伸缩定位孔5、螺栓固定结构6、卡锁装置7，所组成的固定伸缩位置的前车架固定伸缩装置。
本实施例进一步设置为：所述车架固定部分1：空心管状，其一端闭合，在闭合的一端上固定有伸缩杆2，伸缩杆2的截面形状同车架伸缩部分4内孔形状相匹配，使得伸缩杆2只能在车架伸缩部分4内壁伸缩但不能旋转。在伸缩杆2远端圆周上开有一固定销孔3，固定销孔3的孔径与卡锁装置7的卡销外径相匹配；所述伸缩杆2：固定于车架固定部分1闭合端上，伸缩杆2的截面形状与车架伸缩部分4内孔形状相匹配，伸缩杆2可在车架伸缩部分4内壁自由伸缩，但不可旋转。在伸缩杆2另一端圆周上开有一固定销孔3，固定销孔3的孔径与卡锁装置7的卡销外径相匹配，便于卡锁装置7的卡销贯穿伸缩杆2从而固定伸缩杆2；固定销孔3：位于伸缩杆2远端，其大小形状同卡锁装置7的卡销相匹配，便于卡锁装置7的卡销贯穿从而固定伸缩杆2；所述车架伸缩部分4：自行车车架的一部分，空心管状，外径大小形状同车架固定部分1外径相同，其内径大小形状同伸缩杆2外径大小形状相匹配，使得伸缩杆2只能在其内部伸缩但不能旋转。在车架伸缩部分4圆周轴线上均匀分布有若干伸缩定位孔5，定位孔5加工有螺纹，螺栓固定结构6可以旋紧在伸缩定位孔5内，通过按压螺栓固定结构6上的卡锁装置7可以限制伸缩杆2可否伸缩，从而实现车架的伸长与缩短；所述伸缩定位孔5：均匀分布车架伸缩部分4圆周轴线上，孔壁加工有螺纹，使得螺栓固定结构6可以通过螺纹旋紧在车架伸缩部分4圆周上，按压螺栓固定结构6上的卡锁装置7实现了对伸缩杆2能否伸缩的目的；所述螺栓固定结构6：通过螺纹固定在伸缩定位孔5中，在螺栓固定结构6上还固定有卡锁装置7，卡锁装置7可以控制伸缩杆2的伸缩与否；所述卡锁装置7：固定在螺栓固定结构6上，按压一次卡锁装置7，卡销弹起，卡销不再限制伸缩杆2，伸缩杆2可自由伸缩，而拉伸车架至设定长度时，卡锁装置7的卡销将自动落入伸缩杆2固定销孔3中，从而限制伸缩杆2伸缩。
工作原理：车架固定部分1固定有伸缩杆2，在伸缩杆2的远端开有固定销孔3，伸缩杆2在车架伸缩部分4内部可自由伸缩，但不可旋转，卡锁装置7通过螺纹旋紧在车架伸缩部分4圆周上，按压卡锁装置7使得卡销弹起，卡锁装置7不再限制伸缩杆2，伸缩杆2可在车架伸缩部分4内部自由伸缩，但二者不会分离开。这便于自行车的折叠；当打开自行车骑行时，将车架拉伸至设定长度时，卡锁装置7的卡销将自动落入伸缩杆2的固定销孔3中，伸缩杆2锁定不能伸缩，自行车车架稳定满足骑行需要。
实施例 11：
一种增加滑行轮的折叠自行车，其特征在于更换休息架为包括：脚架轴、弹簧钩、固定销、限位销、弹簧、脚架固定板、安装孔、弹簧挂钩、弹性卡、导槽所组成的脚架轴翻折结构。
本实施例进一步设置为：所述脚架轴为实心轴体，轴体上端贯穿有固定销和限位销，脚架轴轴体中部有一弹簧钩挂弹簧，所述弹簧钩位于脚架轴中部，是脚架轴的一部分，通过它使得弹簧可以挂在脚架轴上，所述固定销位于脚架轴的最顶端，并贯穿脚架轴和脚架固定板，固定销到脚架固定板安装孔的距离较目前脚架的距离增大6-8cm,固定销外径大小与脚架轴上的孔径大小相匹配，脚架轴经固定销固定在脚架固定板上，且脚架轴可以以固定销为圆心，在脚架固定板上下限位之间转动，所述限位销位于脚架轴上端，紧邻固定销，同样贯穿脚架轴和脚架固定板，限位销在随脚架轴转动时由脚架固定板上的导槽限制其运动轨迹，所述弹簧：两端各有一个挂钩，分别挂在脚架轴和脚架固定板上，利用它的特点可保持脚架轴稳定，无异响，所述脚架固定板：位于自行车后轴上，在其左上角有一安装孔，可安装固定整个脚架；与安装孔处于同一水平线之上，且相邻处贯穿一固定销，固定脚架轴；在其右上角有一挂钩挂弹簧；位于脚架固定板右下角，即脚架轴转动的上、下限位处各有一截面为三角形的弹性卡，可使脚架轴越过弹性卡时对脚架产生一个支撑作用；与弹性卡相邻处为腰形导槽，限位销在导槽其内部移动，所述安装孔：位于自行车脚架固定板左端，大小形状与自行车后轴直径相匹配，可安装固定整个脚架，所述弹簧挂钩位于脚架固定板右上角，弹簧挂在其上方，所述弹性卡位于脚架固定板右下角，截面为三角形且韧性较好，脚架轴上下转动越过其上方时，弹性卡可对脚架轴产生支撑力，所述导槽位于脚架固定板上，与弹性卡相邻，形状为腰形，限位销在其内部运动。
工作原理：自行车打开时脚架对自行车的支撑：由于改进后的脚架固定销3到安装孔7的距离增大，合适距离为6-8cm ,所以当脚架轴1收起,处于上限位时脚架轴1末端超出自行车后轮外沿，而当脚架轴1放下要支撑自行车时，脚架轴1末端将更加小于自行车后轮外沿，便于自行车立放更加稳定，脚架固定板6上的弹性卡9使得脚架轴1处在上、下限位时保持固定；自行车折叠时脚架对自行车的支撑：首先将脚架轴1从下限位转动至上限位，在这过程中脚架轴1要越过下限位的弹性卡9时，需对脚架轴1施加一个外力，在脚架轴1越过弹性卡9时，由于弹簧5收缩带动脚架轴1向上转动至上限位弹性卡9时停止，再对脚架轴1施加一个外力，使得脚架轴1越过上限位弹性卡9，这时弹性卡9对脚架轴1产生支撑力，使得脚架轴1保持稳定，由于现在固定销3到安装孔7的距离增大了6-8cm,所以此时的脚架轴1末端超出自行车后轮外沿，这样，由自行车折叠后的两轮和处于上限位的脚架轴1三点共同组成一个平面，可使得折叠后的自行车保持立放。
实施例 12：
一种增加滑行轮的折叠自行车，其特征在于增加包括：前叉1、前叉握把2、后上叉3、后上叉握把4，所组成的折叠状态的手提装置。
本实施例进一步设置为：所述前叉1：位于自行车前方两侧，用于固定前轮和实现自行车转向，在其一侧的前叉1上端圆周上横向固定有一实心钢棒，称之为前叉握把2，在前叉握把2顶端为凹陷状，便于自行车折叠后，前叉握把2和后上叉握把4重合时相互有一个支撑力；所述前叉握把2：实心圆柱体，横向固定于前叉1上端圆周上，在其顶端处为向内凹陷状，而后上叉握把4顶端为向外凸起状，这样的形状使得前叉握把2和后上叉握把4在自行车折叠时相互重合并互相支撑，前叉握把1下方圆周上有形状类似手指形状的凹槽，便于手握握2，4把时更加舒适；所述后上叉3：分两侧固定于自行车后轮上方，与后下叉共同组成自行车后叉，在与前叉握把2同侧的后上叉上同样固定有一实心钢棒，称之为后上叉握把4，注意，自行车折叠后位于前叉1上的前叉握把2和位于后上叉3上的后上叉握把4将重合在一起，其重合后的总长度适合手握并提行；所述后上叉握把4：位于前叉握把2同侧的后上叉3上端，为实心钢棒，在其顶端为向外凸起状，便于自行车折叠后，前叉握把2和后上叉握把4重合时相互支撑。
工作原理：顶端向内凹陷的前叉握把2固定在自行车前叉1上端圆周上，在同侧的后上叉3上端固定顶端向外凸起的后上叉握把4，在自行车折叠后，自行车两轮轴心由碰锁结构固定，位于前叉1上的前叉握把2和位于后上叉3上的后上叉握把4将重合，二者顶端的凹凸形状将使得前叉握把2和后上叉握把4重合时相互支撑固定，前叉握把2和后上叉握把4重合后的总长度适合手握并提行；而打开自行车骑行时，前叉握把2和后上叉握把4分离，总长度变为重合时的一半，不会占用额外空间且不影响自行车美观。
实施例 13：
一种增加滑行轮的折叠自行车，其特征在于增加包括：自行车后车架、行李稳杆、棘轮结构、释放钮的后车架附加自由稳杆装置。
本实施例进一步设置为：所述的自行车后车架安装于自行车后轮上，两个固定点分别位于自行车立管和后轴上，在其后车架面板后侧钢条上分别由棘轮结构固定有两根行李稳杆，所述行李稳杆位于自行车后车架面板后侧钢条上，其一端通过棘轮结构连接在自行车后车架面板上，且行李稳杆可绕棘轮结构在0-90°范围内转动和固定，所述棘轮结构由棘轮、棘爪、弹簧片等部件组成，行李稳杆连在棘爪上，释放钮位于棘轮结构后方，当按住释放钮，并转动行李稳杆时，棘爪也同时绕棘轮转动，松开释放钮，外力停止转动行李稳杆时，棘爪也停止转动且棘爪就会卡住棘轮，从而行李稳杆就卡在当前的角度并卡紧，便于行李的固定，所述释放钮位于棘轮结构上，当按住释放钮行李稳杆可绕棘轮结构转动，而松开释放钮时，行李稳杆就会被棘轮结构卡紧，便于固定行李。
工作原理：自行车行李稳杆2通过棘轮结构3连接在自行车后车架1面板上，棘轮结构3类似于棘轮扳手原理，当我们放置行李在自行车后车架1上，且需要固定行李时，就需要按住释放钮4用外力转动行李稳杆2到行李的高度后，松开释放钮4并停止转动行李稳杆2，行李稳杆2固定在该角度并卡紧行李；当不需要行李稳杆2固定行李时，先按住释放钮4用外力转动行李稳杆2到与自行车后车架1面板夹角为0°的位置，松开释放钮4行李稳杆2停止转动并固定。
实施例 14：

本实施例进一步设置为：所述箱包状的外包装装置，运用卷帘门的结构，包装薄片双双从位于后轮的最后的两侧位置的薄片筒中拉出，向折叠处延展，并在折叠处卡住，使包装薄片成为折叠车箱包状的外包装。
工作原理：卷帘门从卷帘门筒里拉出，在地面锁住，卷帘门就把门关上了；同样的原理，从折叠车后轮的后面的类似卷帘门筒的装置，从装置的筒口拉出保护 自行车避免和外界相碰撞的包装薄片，拉到折叠处卡住，就保护了一边，另一边也这样做，就形成了箱包状的外包装。
实施例 15：
根据增加卷帘门式箱包状的外包装装置，收纳薄片的薄片筒为了美观，在骑行状态时，平放在自行车行李架位置，使用时翻转倒下来，再拉出薄片。
实施例 16：
根据增加卷帘门式箱包状的外包装装置，收纳薄片的薄片筒，在折叠车骑行状态时需要有减震措施，避免骑行的过程中发出异响。
