The invention relates to the technical field of mother and baby equipment, and discloses an automatically-controlled overspeed protection trolley for infant life, which comprises a fixed shaft, a locking groove is formed in the fixed shaft, an electromagnet is fixedly connected in the locking groove, first springs are fixedly connected to the top and the bottom of the electromagnet, and locking blocks are fixedly connected to the outer sides of the first springs. a permanent magnet is fixedly connected into the locking block, and second springs are fixedly connected to the two sides of the fixing shaft. By mutual cooperation of the electromagnet, a first spring, a locking block and a permanent magnet, the electromagnet is powered on to generate a magnetic field and interacts with the permanent magnet, the locking block is driven to overcome the elastic force effect of the first spring to move, and the locking block and a control shaft are released from the clamping state; and through mutual cooperation of the control shaft, the damping block and the rolling wheel, the damping block moves outwards and is clamped with the matching groove, so that the rolling wheel stops rotating under the action of friction force, and the overspeed protection function of the product is achieved.

    本发明涉及母婴设备技术领域,且公开了一种婴儿生活用自动控制的超速保护手推车,包括固定轴,所述固定轴内部开设有锁定槽,锁定槽内部固定连接有电磁铁,电磁铁顶部和底部均固定连接有弹簧一,弹簧一外侧固定连接有锁定块,锁定块内部固定连接有永磁体,固定轴两侧均固定连接有弹簧二。该婴儿生活用自动控制的超速保护手推车,通过电磁铁、弹簧一、锁定块、永磁体的相互配合,电磁铁通电产生磁场并与永磁体相互作用,带动锁定块克服弹簧一弹力作用移动,使得锁定块与控制轴解除卡接状态,再通过控制轴、阻尼块、滚轮的相互配合,阻尼块向外移动与配合槽相互卡接,使得滚轮在摩擦力的作用下停止旋转,实现了产品的超速保护功能。
