如图 5a、图 5b、图 6a和图 6b所示，为了增加该健身车的可变化性，另一实施例是将活动连接架 B设置为活动连接架 B主体、前叉片 B2和后车架 B4三个主要部分，该主体尾部设有后叉片 B3，后叉片 B3上设有纵向的叉片槽 B31，后车架 B4的头部连接一后架锁紧装置 M。该后架锁紧装置 M为一支立管，内装有轴承， '轴承的芯轴 M2与后车架 B4的前段相连接，芯轴可用空心式快拆芯轴组或普通芯轴。 As shown in FIGS. 5a, 5b, 6a, and 6b, in order to increase the variability of the exercise bike, another embodiment is to set the movable connecting frame B as the main body of the movable connecting frame B, the front fork piece B2, and the rear vehicle. There are three main parts of the frame B4. The rear part of the main body is provided with a rear fork piece B3. The rear fork piece B3 is provided with a longitudinal fork piece groove B31. A head of the frame B4 is connected to a rear frame locking device M. The rear frame locking device M is a standpipe with a bearing inside. The core shaft M2 of the bearing is connected to the front section of the rear frame B4. The core shaft can be a hollow quick-release core shaft group or a common core shaft.

如图 5a和图 6a所示，该后架锁紧装置 M的芯轴 M2***该叉片槽 B31内，在锁紧装置 M未锁紧时，该锁紧装置 M'可带动后车架 B4在叉片槽 B31内前后滑动，在后架锁紧装置 M滑动到叉片槽底时，由于后车架 B4上的凸决 B41镶入叉片槽 B31内，活动连接架 B主体与后车架 B4之间不能相对转动，将后架锁紧装置 M锁紧即可做后车架 B4固定方式骑行。 As shown in FIG. 5a and FIG. 6a, the mandrel M2 of the rear frame locking device M is inserted into the fork groove B31. When the locking device M is not locked, the locking device M 'can drive the rear frame B4 Slide back and forth in the fork slot B31, and when the rear frame locking device M slides to the bottom of the fork slot, since the convex block B41 on the rear frame B4 is fitted into the fork slot B31, the main body of the movable connection frame B and the rear vehicle The frames B4 cannot rotate relative to each other, and the rear frame locking device M can be locked to ride the rear frame B4 in a fixed manner.

用空心快拆芯轴组合结构时，叉片 B3 的尾部上开一对叉片槽 B31，后车架 B4靠近立管的位置上下各有一个凸块 B41，当凸块 B41位于叉片槽 B31内时，后车架不能绕轴承芯轴 B7转动。 When the hollow quick-release mandrel combination structure is used, a pair of fork blade grooves B31 are opened at the tail of the fork blade B3, and a bump B41 is arranged on the upper and lower positions of the rear frame B4 near the riser. When the bump B41 is located in the fork blade groove B31 When inside, the rear frame cannot rotate around the bearing mandrel B7.

在后架锁紧装置 M向后滑动而使凸块 B41滑出该叉片槽 B31的位置时，后车架 B4可绕芯轴 M2转动，将其后拉销定时，后车架 B4可绕后车架立管的轴承芯轴 M2转动，车子增加了一个后轮转动自由度，可造成 Z字形及其它各种造型。 When the rear frame locking device M slides backward and the projection B41 slides out of the position of the fork groove B31, the rear frame B4 can be rotated about the core shaft M2, and the rear frame pin can be timing, and the rear frame B4 can be wound around. The bearing mandrel M2 of the rear frame riser rotates, and the vehicle adds a degree of freedom to rotate the rear wheels, which can cause zigzag and other various shapes.

若采用普通芯轴时，则凸块 B41的位置变成各一个钻孔，用***插销的方法将二者定位。 If an ordinary mandrel is used, the position of the bump B41 becomes a drill hole, and the two are positioned by inserting a pin.

如图 8所示，若不采用叉片槽 B31 , 则可采用 2组圆孔，其中一组圆孔用于安装后车架 B4立管上的轴承芯轴 M2，另一组孔用作插销孔。将插销***孔中，使二者定位不可摆转，将插销拨出，活动连接架 B主体及后车架 B4之间即可相对摆转。 As shown in FIG. 8, if the fork blade groove B31 is not used, two sets of round holes may be used, one of which is used to install the bearing mandrel M2 on the rear frame B4 standpipe, and the other set of holes is used as a latch. hole. Insert the pin into the hole so that the two cannot be swung. If the pin is pulled out, the movable connection frame B and the rear frame B4 can be swiveled relative to each other.

如图 2和图 9所示，后车身为一独轮车 C总成，在该独轮车的芯轴的两端在支撑独轮车架 C1的外轴承座 C3并排另分别加设有一组内轴承座 C2，后车架 B4 安装在该内轴承座 C2上。与普通独轮车不同的是其后轮轴 C5的轴承安装位较长，除安装其独轮车架 C1的车叉的轴承外，还可多安装一对轴承，该轴承外壳可与后车架 B4的后叉端用螺丝固定，使后车架 B4以独轮车芯轴可相互转动，表演者将前轮组件提离地面时，其与后面的独轮车互不影响，独轮车可以自如蹬走。工业应用性 As shown in FIG. 2 and FIG. 9, the rear body is a unicycle C assembly. At both ends of the unicycle's mandrel, the outer bearing housing C3 supporting the unicycle frame C1 is arranged side by side, and a set of inner bearing housings C2 are respectively added.
