一种垂直升降式自行车停车架，如图1所示为本实用新型的结构原理图，包括立柱100、升降臂200、氮气弹簧02、第一动滑轮组件0301、第二动滑轮组件0302、钢丝绳04、第一定滑轮组件05、第二定滑轮组件06，立柱 01竖直方向设有两个氮气弹簧02，两个氮气弹簧02的一端设与立柱100的顶部，另一端分别连接第一动滑轮组件0301、第二动滑轮组件0302，立柱100顶部设有第一定滑轮组件05、第二定滑轮组件06，钢丝绳04的一端固定于立柱100上，另一端依次绕过第一动滑轮组件0301、第二定滑轮组件06、第二动滑轮组件0302、第一定滑轮组件05与升降臂200连接，在本实施例中，升降臂200包括立架210和横架220，立架210底部还设有底架230，钢丝绳04与底架230连接，氮气弹簧02伸缩平缓，带动升降臂200升降速度平缓，撞顶冲击力小，有效防止车架内的自行车由于惯性上窜跌落，极大提升安全性，同时因为升降臂200的静音效果好，极大降低停车架升降时的噪音，采用钢丝绳04替代现有技术常用的拉簧或卷簧，没有锋利的外露部分，也极大的提高了安全性。
立柱100的顶端还设有立柱上封板07，第一定滑轮组件05、第二定滑轮组件06高度不同，两者设置安装于立柱上封板07上，且两者在上封板07上的垂直投影成八”字形，方便钢丝绳04绕绳不易缠绕在一起，两个氮气弹簧02的固定缸022的一端有安装孔023，串联轴09穿过安装孔023将氮气弹簧02安装于立柱上封板07，结构紧凑。
第一动滑轮组件0301、第二动滑轮组件0302结构相同，均包括动滑轮组件主体板031、绳轮032、绳轮安装轴033、运动轮034、运动轮安装轴035；绳轮032通过绳轮安装轴033安装于动滑轮组件主体板031上，运动轮034通过运动轮安装轴035安装于动滑轮组件主体板031两侧；运动轮034在立柱100内部可不卡滞的滚动。
立柱100上设有第一限位挡块140，横架220的底部设有第一拉杆221，第一拉杆221的中间设有第一拉簧222，第一拉杆221的一端设有第一限位块223，另一端设有把手224；设备运行过程中，升降臂200从立柱100的最高点运行至最低点，在第一限位挡块140的导向作用下，第一限位块223经过压缩回弹，卡住第一限位挡块140使得升降臂200可靠的定位于最低点，在自行车放入升降臂200后，拉动把手224，第一限位块223脱离第一限位挡块140，升降臂200在第一卷簧101和第二卷簧103的作用力下，升高至立柱100的最高点，第一拉簧222对第一拉杆221起到自动复位作用。
第一限位块223同时通过第一限位块拉簧225与横架220连接，第一限位块拉簧225对第一限位块223起到自动复位作用，使用操作更为简单省力，第一限位块223的复位更加安全可靠，结构更为稳定。
立柱100上还设有第二限位挡块150，底架230上设有可活动的第二限位块231，第二限位块231通过第二拉簧232与底架230连接，横架220上设有转动杠杆250，转动杠杆250的一端连接有车轮托架251，转动杠杆250的中部与横架220通过转动轴252连接，转动杠杆250的另一端通过杠杆拉簧253与横架220连接的同时连接有第二拉杆254，第二拉杆254的末端设有拉钩255，拉钩255同时通过连接螺柱258与横架220可活动连接，拉钩255与第二限位块231的垂直凸起可活动连接，第二限位块231与第二限位挡块150构成可活动的限位机构，当自行车放入停车架的横架220内时，自行车的车轮自重使得车轮托架251带动转动杠杆250转动，从而使得拉钩255带动第二限位块231脱离第二限位挡块150的限位，解除第一重限位，然后拉动把手224，第一限位块223脱离第一限位挡块140，升降臂200在第一卷簧101和第二卷簧103的作用力下，升高至立柱100的最高点，第一拉簧222对第一拉杆221起到自动复位作用。
拉钩255同时通过拉钩弹簧256与横架220连接，利用拉钩弹簧256的柔性弹力自复位，使用舒适，噪音小，使用寿命长。
横架220设有转动限位柱226，转动杠杆250设于转动限位孔257，转动限位柱226设于转动限位孔257内，使转动杠杆250在一定的合理范围内转动，结构合理紧凑。
立柱100的截面形状包括第一定位槽013与第二定位槽014，运动轮034与立架轮240分别可活动的设置于第一定位槽013与第二定位槽014内，结构紧凑，便于生产安装。
立柱100的内部设有T形件11，运动轮034通过运动轮安装轴035安装于动滑轮组件主体板031两侧，一侧运动轮034在立柱截面的第一定位槽013滚动，另一侧在T形件11上滚动，实现动滑轮组件主体板031两侧的运动轮034大小一致可互换，便于生产制造、装配维修。
在本实施例中，氮气弹簧02为变阻尼氮气弹簧；氮气弹簧02驱动升降臂200从立柱100最低点升至最高点的过程中，升降臂200先加速后匀速，削减了氮气弹簧02伸展时的惯性冲击，使用时感受更为舒适，且使用寿命更长。
实施例2
与实施例基本相同，其区别在于如图18所示，在本实施例中，立柱100的内部没有T形件11，而是替代的是在立柱100的空心筒状内壁上一体成型有T形凸起015，运动轮034通过运动轮安装轴035安装于动滑轮组件主体板031两侧，一侧运动轮034在立柱截面的第一定位槽013滚动，另一侧在T形凸起015上滚动。
总之，以上所述仅为本实用新型的较佳实施例，凡依本实用新型申请专利范围所作的均等变化与修饰，皆应属本实用新型专利的涵盖范围。
