Abstract

A method for controlling the safety of an electric hand truck and an apparatus therefor are disclosed. The method for controlling the safety of an electric hand truck comprises the steps of: determining whether user manipulation is present due to a user input for the electric hand truck; and, if there is no user manipulation, then braking in a softlock manner in which instead of power being applied to the electric motor which drives the wheels of the electric hand truck, electrodes of the electric motor are short-circuited.

Description

technical field [0001] The following description relates to a technique for stopping the speed of a moving vehicle. Background technique [0002] Recently, in shopping malls, express delivery, industrial sites, etc., there are many cases where goods are transported using mobile carts for various purposes. [0003] For example, Patented Utility Model Publication No. 20-0440927 (registration date: July 2, 2008) discloses a structure of a transport cart used for short-distance movement of packing boxes in warehouses or logistics centers. [0004] When loading heavy objects on the mobile trolley, the user needs to exert considerable force in order to move the mobile trolley, and it is even more difficult to properly operate the mobile trolley loaded with items to move in the desired direction. So transporting items is accompanied by considerable difficulties. [0005] In response to this, a method has been attempted in which a motor is provided on a dolly and the motor is driv...
