The invention is suitable for the technical field of vehicles, and provides a liftable wheel which comprises a wheel frame, two sets of crank sliding block mechanisms and a wheel body. Sliding grooves are formed in the two sides of the wheel frame, and the two crank sliding block mechanisms are arranged on the two side walls of the wheel frame correspondingly. The crank sliding block mechanism comprises a crank, a connecting rod and sliding blocks, and the two sliding blocks can slide up and down along the sliding grooves; the connecting part of the two cranks forms a pedal; the lower rotating end of the crank is connected with the upper rotating end of the connecting rod; the two sliding blocks are connected to the two sides of the wheel body, and when the pedal is pressed downwards, the sliding blocks slide downwards along the sliding grooves. When the pedal is lifted upwards, the sliding block slides upwards along the sliding groove. When the sliding block slides up and down, the vehicle body is driven to move up and down. According to the liftable wheel provided by the invention, when a ground running mode and a rail running mode are switched, a user only needs to press or lift the pedal, the operation is simple and easy, and the problems that in the prior art, the number of wheel assemblies is large, and the switching process is complex and tedious are solved.
本发明适用于交通工具技术领域,提供了一种可升降车轮,包括车轮架、两套曲柄滑块机构和车轮本体;车轮架两侧开设有滑槽,两套曲柄滑块机构分别设置在车轮架的两侧壁;曲柄滑块机构包括曲柄、连杆和滑块,两个滑块可沿滑槽上下滑动;两个曲柄的连接部构成踏板;曲柄的下转动端连接连杆上转动端,连杆的下转动端连接滑块;两个滑块连接在车轮本体两侧,当向下按压踏板时,滑块沿滑槽向下滑动;当向上提起踏板时,滑块沿滑槽向上滑动;滑块上下滑动时,带动车本本体上下移动。本发明提供的可升降车轮,在进行地面行驶模式和轨道行驶模式切换时,使用者只需按压或提起踏板,简单易操作,解决了现有技术中车轮组件多、切换过程复杂、繁琐的问题。
