Problems solved by technology

It can be seen that no matter which patent in the two patents only considers the safety problem during the braking process, it only uses the brake mechanism to brake, and does not take into account the possible safety problems that may occur when pushing the trolley on a slope.

Abstract

The invention provides a trolley capable of achieving safe pushing on a slope. Front wheels of the trolley are correspondingly provided with brake mechanisms; first pressure sensors are arranged on one side, facing towards a user, of a handle; a second pressure sensors are arranged on the upper surface of the handle; a third pressure sensor is arranged on a front side baffle of a frame body; a horizontal sensor is further arranged on the trolley; when the horizontal sensor detects that the trolley is inclined and the third pressure sensor detects that pressure applied by articles in the framebody on the front side baffle is increased, a control circuit determines that the trolley descends along the slope and judges whether the second pressure sensors detect pressure; if so, the control circuit determines that the user holds the handle and controls the brake mechanism to perform progressive braking till the brake mechanisms achieve complete braking; and when the first pressure sensor detects the pressure, the control circuit determines that the user pushes the trolley, and controls to reduce a braking force of the brake mechanisms by a level.

Description

technical field [0001] The invention belongs to the field of trolleys, and in particular relates to a trolley capable of safely pushing on slopes. Background technique [0002] As a common tool in daily life, trolleys usually include supermarket shopping carts and airport luggage trolleys. In the prior art, the trolleys are mostly driven by manual control. In order to ensure the safety of the pushing process, some trolleys are also equipped with a brake mechanism. For example, there is a pressing link on the airport luggage trolley. Link to release the brake mechanism for braking. But at present, the handcart is provided with a braking mechanism only to stop the handcart. In the process of stopping the trolley, the R&D personnel considered various scenarios. For example, in the invention patent with application number 201811238962.5, a method and system for automatic braking of the trolley are disclosed. Control the automatic braking of the trolley, so as to eliminate the...
