Electric double-leaf inward-swinging door system

Abstract

The invention discloses an electric double-leaf inward-swinging door system. The electric double-leaf inward-swinging door system comprises door sheets, a tray arranged above the door sheets, a driving device for driving the door sheets to be opened or closed, and a transmission mechanism. The driving device comprises a push rod tail bed, a motor and an electric push rod which are arranged on the tray. The transmission mechanism comprises a bracket, a main rocker arm, an output shaft, connection rods and a swinging arm. The push rod tail bed is provided with the electric push rod driven by the motor, the electric push rod is connected with the main rocker arm through a main connection rod, the main rocker arm is fixed to the output shaft, and the output shaft is fixed to the tray through the bracket. The output shaft is provided with the swinging arm, the output shaft penetrates through the center of the swinging arm, the two ends of the swinging arm are connected with the left connection rod and the right connection rod correspondingly, the left connection rod and the right connection rod are connected with a left door spindle and a right door spindle through a left rocker arm and a right rocker arm correspondingly, and the left door spindle and the right door spindle are connected with the left door sheet and the right door sheet correspondingly. The electric double-leaf inward-swinging door system adopts mechanical transmission and is free of vulnerable parts, the reliability of products is high, and daily maintenance is not needed.

Description

technical field [0001] The invention relates to an electric double-leaf inner swing door system used on passenger cars. Background technique [0002] The passenger doors of existing public transport vehicles are generally pneumatic inward swing passenger doors, and the pneumatic outward swing passenger doors are generally driven by cylinders. There are the following disadvantages: 1. Pneumatic components are vulnerable parts with a high failure rate and require frequent maintenance and replacement. 2. Since the power source of the door is compressed air, the state of the door is affected by the air pressure of the vehicle, and the speed of opening and closing the door is prone to be unstable. When the air pressure of the vehicle is low, the door is loose and wide, which is prone to safety hazards. 3. The vehicle needs to convert the energy multiple times into compressed air, and then drive the door to open, which consumes a lot of energy in the process. [0003] With the d...

Problems solved by technology

[0002] The passenger doors of existing public transport vehicles are generally pneumatic inward swing passenger doors, and the pneumatic outward swing passenger doors are generally driven by cylinders. There are the following disadvantages: 1. Pneumatic components are vulnerable parts with a high failure rate and require frequent maintenance and replacement

2. Since the power source of the door is compressed air, the state of the door is affected by the air pressure of the vehicle, and the speed of opening and closing the door is prone to be unstable, and when the air pressure of the vehicle is low, the door is loose and wide, which is prone to safety hazards

3. The vehicle needs to convert the energy multiple times into compressed air, and then drive the door to open, the process consumes a lot of energy

The disadvantages of the existing structure are: 1. Pneumatic components are easy to age, have a high failure rate, and need to be replaced frequently; 2. The state of the car door is affected by the air pressure of the vehicle body, and the smoothness of opening and closing the door is unstable; 4. The kinetic energy of compressed air requires multiple conversions of energy, and the energy consumption is high, which is not conducive to energy saving and emission reduction
