The cart comprises a cart frame, a front wheel frame, a rear wheel frame, a pushing handle frame, an automatic speed reducing mechanism and a linkage brake mechanism, the front wheel frame is arranged at the bottom of the front end of the cart frame, the rear wheel frame is arranged at the bottom of the rear end of the cart frame, the pushing handle frame is arranged at the top of the rear end of the cart frame, and the automatic speed reducing mechanism is arranged on the pushing handle frame. The front wheel capable of rolling is arranged on the front wheel frame, the automatic speed reducing mechanism is arranged between the front wheel and the front wheel frame, and when a slope is encountered, the automatic speed reducing mechanism achieves automatic speed reduction of the front wheel. The two rear wheels of the cart can be conveniently braked and locked at the same time, in this way, the braking efficiency is improved, meanwhile, when the cart encounters a slope, automatic speed reduction is achieved, and safety is guaranteed.

    本发明公开了一种具备刹车与自动减速的推车,包括车架、前轮架、后轮架、推手架、自动减速机构与联动刹车机构,其中在车架的前端的底部设置有前轮架,在车架后端的底部设置有后轮架,在车架的后端顶部设置有推手架,在前轮架上设置有可以滚动的前轮,在前轮与前轮架之间设置有自动减速机构,当遇到斜坡的时候,自动减速机构实现对前轮的自动减速;在后轮架上设置有后轮,在两个后轮上设置有联动刹车机构:便于同时对推车的两个后轮进行刹车锁止,这样提高刹车效率,同时当遇到斜坡的时候,自动减速,这样保证安全。
