The invention relates to the field of wheelchair advancing control methods, and discloses an automatic braking method and an automatic braking mechanism of an unpowered walking device, a wheel of the unpowered walking device is connected with a hydraulic pump linked with the wheel, and the hydraulic pump is used as a hydraulic braking power source of the unpowered walking device; in the advancing process of the unpowered walking device, the running wheels drive the hydraulic pump to run, and braking medium liquid is driven to flow circularly through running of the hydraulic pump; a flow control valve is arranged on a circular flow path of braking medium liquid, the braking speed point of the unpowered walking device is controlled by controlling the opening degree of the flow control valve, and when the advancing speed of the unpowered walking device reaches the braking speed point, hydraulic braking is automatically conducted. According to the automatic braking method provided by the invention, automatic braking can be realized, and the braking speed point can be changed, so that the braking application requirements of different types of unpowered walking devices can be met.

    本发明涉及轮椅行进控制方法领域,公开一种无动力行走装置的自动刹车方法及自动刹车机构,其在无动力行走装置的车轮上连接与之联动的液压泵,并将所述液压泵作为所述无动力行走装置的液压制动动力源;在所述无动力行走装置的行进过程中,通过运转的车轮带动所述液压泵运转,通过所述液压泵的运转带动制动介质液循环流动;在制动介质液的循环流动路径上设置流量控制阀,通过控制所述流量控制阀的开度来控制所述无动力行走装置的制动速度点,当所述无动力行走装置的行进速度达到所述制动速度点时,自动进行液压制动。本发明提供的自动刹车方法不仅能实现自动刹车,并且,可以改变制动速度点,以满足不同种类无动力行走装置的刹车应用需求。
