The invention discloses a novel barrier-free electric wheelchair star wheel. The star wheel is composed of an axle, a bearing, a bolt, a frame, a nut, a universal moving ball, a convex circular track, a rotating triangular bracket, a movable supporting column and the like; the star wheel is characterized in that a supporting square cylinder in the rotating triangular bracket is connected with a ball cap in the universal moving ball, and the convex circular track is assembled on a bearing sleeve in the rotating triangular bracket and is fixed by the nut; and a support plate in the convex circular track is connected and fixed with the frame through the bolt; a movable rod in the movable supporting column is connected with a stud on the supporting square cylinder in the rotating triangular bracket; one end of a supporting column in the movable supporting column is arranged outside an outer circular track in the convex circular track; and the other end of the supporting column is arranged on the ball cap in the universal moving ball. According to the barrier-free electric wheelchair star wheel, the universal moving ball can advance in any direction in the advancing process, when a barrier exists, the triangular bracket is rotated to drive the universal moving ball to rotate together and climb over the barrier, and compared with a known electric wheelchair, the barrier-free electric wheelchair star wheel has flexibility; and the advantages that the structure is simple and compact, and the manufacturing cost is low are achieved.

    一种新型无障碍电动轮椅车星形轮,有车轴、轴承、螺栓、车架、螺母。万向移动球,凸圆型轨道,转动三角支架,活动之柱等组成。其特征在于转动三角支架内中的支撑方筒与万向移动球内中的球帽联接,凸圆型轨道装配在转动三角支架内中的轴承套上,用螺母固定。凸圆型轨道内中的支撑板与车架有螺栓连结固定。活动支柱内的活动杆与转动三角支架内中的支撑方筒上的螺柱联接。活动立柱内中的立柱一端在凸圆型轨道内中的外圆轨道外。另一端在万向移动球内中的球帽上,无障碍电动轮椅车星形轮,在行进中万向移动球任何方向都可以行进,在有障碍时,转动三角支架带动万向移动球一起转动,翻越障碍,与公知的电动轮椅相比,具有灵活性。结构简单,紧凑制造成本低等优点。
