An electric double-opening inner swing door

Abstract

The invention discloses an electric double open inner swing door, comprising door leaves and two drive devices driving the door leaves to be opened and closed; each drive device comprises a door spindle, a fan-shaped gear arranged on the door spindle in a penetrating manner, a drive mechanism used to drive the fan-shaped gear to rotate, and a mounting plate used to movably mount the drive mechanism; each drive mechanism comprises a gear and an electromotor driving the gear to rotate, when the drive mechanism is moved to enable the gear to be meshed with the fan-shaped gear, the electromotor is started to drive the gear to drive the fan-shaped gear to rotate, such that the door spindle realizes door opening and closing actions. The electric double open inner swing door is low in noise, stable in output and energy-saving and environment-friendly, a crankshaft connecting rod or coupler is not adopted as the drive device, the transmission efficiency is improved, full power output can be realized, the two door leaves can be separately opened and closed, the structure is simple, operation is reliable, the service life is long and the electric double open inner sing door has very high reliability.

Description

technical field [0001] The invention relates to an urban public transport vehicle door system, in particular to an electric double-opening inner swing door. Background technique [0002] Existing buses and buses usually use pneumatic inner swing doors driven by cylinders, which convert electrical energy into gas energy, and then convert gas energy into kinetic energy, and there is a certain waste of energy. The impact is unstable, the degree of intelligence is low, the pneumatic components are easy to age, the life is low, and the noise is loud during the opening and closing process, and there is no anti-pinch function or the anti-pinch function is easy to fail and hurt people, and there are certain safety hazards. [0003] In addition, the existing drive devices for inner swing doors usually use a coupling or a crank connecting rod to realize the transmission between the cylinder and the door shaft, which has low transmission efficiency, high power, and is not energy-saving...

Problems solved by technology

[0002] Existing buses and buses usually use pneumatic inner swing doors driven by cylinders, which convert electrical energy into gas energy, and then convert gas energy into kinetic energy, and there is a certain waste of energy. The impact is unstable, the degree of intelligence is low, the pneumatic components are easy to age, the life is low, and the noise is loud during the process of opening and closing the door, there is no anti-pinch function or the anti-pinch function is easy to fail and hurt people, and there are certain safety hazards

[0003] In addition, the existing drive devices for inner swing doors usually use a coupling or a crank connecting rod to realize the transmission between the cylinder and the door shaft, which has low transmission efficiency, high power, and is not energy-saving and environmentally friendly; in addition, the two doors of some door systems must be linked. In an emergency situation, if one door is blocked, the other door cannot be opened, causing a great safety hazard, and the driver cannot know the location and cause of the fault when the fault occurs, causing inconvenience to fault repair and recovery
