Problems solved by technology

[0002] Inside the subway car, there are often pull rings that can be grasped by passengers. These pull rings can connect passengers to the car to ensure that passengers can still stand stably when the vehicle accelerates or stops suddenly. The number of pull rings in the subway car is limited, and the traditional pull rings can only provide a space for one person to grasp. Therefore, when there are too many people in the car, some people will not be able to grasp the pull rings, so there is a certain safety risk.

Abstract

The invention discloses an intelligent subway pull ring device and a control method. The intelligent subway pull ring device comprises a plurality of pull rings installed on a handrail in a sliding mode, every two pull rings are arranged in a group, every two adjacent pull rings in the same group are arranged in a bilateral symmetry mode, and grip cavities are formed in the lower sides of the pull rings in the same group and provided with grips with rotating cavities; each rotating cavity is rotationally connected with an extension rod, a limiting cavity with a limiting ball is formed in the pull ring, the limiting ball matched with the extending rod is slidably arranged in the limiting cavity, a first moving cavity and a second moving cavity which are vertically symmetrical are formed in the connecting position of the pull ring and the handrail, and moving driving assemblies for driving the pull ring to move are arranged in the first moving cavity and the second moving cavity; and after the two extension rods of the same group of pull rings are vertical and matched with the limiting ball in place, each pull ring forms a single pull ring device for one hand to hold, and after the two extension rods of the same group of pull rings are separated from the limiting ball and overturned to be in horizontal butt joint, the two pull rings form a combined pull ring device for three hands to hold, so that the utilization rate of the pull rings is improved.

Description

technical field [0001] The invention relates to the technical field of subway vehicle accessories, in particular to a smart subway pull ring device and a control method. Background technique [0002] Inside the subway car, there are often pull rings that can be grasped by passengers. These pull rings can connect passengers to the car to ensure that passengers can still stand stably when the vehicle accelerates or stops suddenly. The number of pull rings in the subway car is limited, and the traditional pull rings can only provide a space for one person to grasp. Therefore, when there are too many people in the car, some people will not be able to grasp the pull rings, and there is a certain safety risk. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smart subway pull-ring device and a control method for the above-mentioned defects in the prior art. [0004] According to the present invention, a smart subway p...
