The invention relates to a trundle, in particular to an NFC inductive control brake trundle. The trundle comprises a trundle frame provided with a center shaft in the transverse direction, a locking motor, a brake block, a brake rod, a spring and an NFC electric control module, side wheels penetrating through the center shaft are arranged on the left side and the right side of the trundle frame respectively, inner teeth are arranged on the inner sides of the side wheels, and the spring is connected to the outer side of the brake rod in a sleeving mode; the brake rod is provided with a transverse rod which projects along the laterial side, and the surface side of the brake block is provided with a plurality of outer teeth; the back side of the brake block abuts against the non-extrusion endof the spring up and down, the NFC electric control module is electrically connected with the locking motor, and the brake rod is in transmission connection with the locking motor so that the springcan be released along with rotation of the cross rod, and therefore the spring is matched with the brake block in an abutting mode and pushes the brake block to inner teeth of the edge wheel. The trundle is controlled through NFC induction, the trundle can be rapidly and reliably braked and locked in direction, the implementation process is simple and flexible, and safety is good.

    本发明涉及一种脚轮,尤其是一种NFC感控制动脚轮。该脚轮包括沿横向设有中心轴的轮架、锁止电机、制动块、制动杆、弹簧和NFC电控模块,轮架左右两侧分别设有穿过中心轴的边轮,边轮的内侧设有内齿,弹簧套接在制动杆的外侧,制动杆设有沿其旁侧凸出的横杆,制动块的表侧设有若干外齿,制动块的背侧与弹簧的非挤压端上下抵接,NFC电控模块与锁止电机电连接制动杆与锁止电机可传动连接,以使弹簧可随横杆转动而释放,从而与制动块顶压配合并将制动块推至边轮的内齿。本发明通过NFC感应控制脚轮,可快速对脚轮实现可靠的制动和锁紧方向,实现过程简单灵活且安全性好。
