Sensitive Edge Sliding Plug Door Passenger Protection For Pure Electric Bus

Product Name: Sensitive Edge to protect passenger electric sliding plug door for 100% electric bus

1. The main features :

• Smooth motion. It combines the linear bearing’s sliding and roller bearing’s rolling mechanism to accomplish the sliding and swinging motion during the door open and close. It also utilizes rotating columns to balance the upper and lower part of door panel plugging motion;
• High safety. It utilizes the over-center auto locking to make sure that the door will not open accidentally. The door will be locked even tighter if pushed by passenger. It also utilizes the pressure wave sensitive edge combined with current measurement as secondary sensitive edge;
• High reliability. Power driven swinging motion for the smooth door movement;
• Energy Saving. Swinging and sliding driven by single motor for power efficiency;
• Superior sealing. It insulates noise from the outside and reduces the energy loss of the air conditioner;
• Sleek outlook. The outlook is very clean by using the curve-matched door panel and the inner sealing.

2. Mechanism :
The door system consists of mechanical system and electrical system. Mechanical system includes door operator, door shaft and door panels. The electrical system includes power supply and controller. The door operator consists of driving mechanism, plugging mechanism, hanging mechanism, guiding mechanism, and locking & unlocking mechanism.

• Driving mechanism includes DC motor and multi-head ball screw to achieve smooth motion and high reliability. The DC motor is connected to shaft connector, gear box, ball screw and driving nut in order. Driving nut is then connected to the door hanger and door panel. The door panel is horizontal sliding as long as ball screw rotates;
• Plugging mechanism includes fix plate, moving plate, rotating shaft, plug driving rod, plug following rod. Hanging system includes hanger and guide rod. Hanger is connected to the door panel and meanwhile is also connected to the guide rod through the linear bearing. Therefore the weight of door panel is transferred to the guide rod, which is installed on the moving plate. When motor rotates, it drives the rotating shaft to rotate through planetary gear box. The rotating shaft then drives the plug driving rod to rotate. It makes the moving plate move in and out by using connecting rod and sliding block mechanism. Because the door hanger is also installed on the moving plate, the door panel can be driven in and out to achieve the plugging motion;
• Guiding mechanism consists of upper guide track and lower guide track. Upper guide track is installed on the fix plate. When the door panel moves, the roller installed on the hanger will rotate around the guide track. The lower guide track is installed on the lower inner part of the door panel. The lower roller installed on the swing arm is also rotating around the lower guide track when the door panel is sliding. The sliding motion and plugging motion are controlled by roller and guide track mechanism;
• Locking and unlocking mechanism includes rotating shaft, plug driving rod, plug following rod, unlocking disc, and emergency handle. When motor runs, it drive the rotating shaft to rotate through planetary gear box and then drive the plug driving rod and plug following rod to rotate. The moving plate is locked since the plug following rod is rotated over pivot center. The door panel is locked since it is connected to the door hanger and then to the moving plate. The emergency handle is connected to the unlocking disc directly or through cable. When emergency handle is activated, the unlocking disc which is fixed on the rotating shaft will rotates. As soon as the rotating shaft rotates on the opposite direction, it will drive the plug driving rod and the plug following rod out of over-center. The moving plate and the door panel are unlocked;
• The electrical door control system (EDCU) is developed by Ivy itself. EDCU controls the door movement by getting orders from vehicle. The function of EDCU is to control individual door movement and communicate with other EDCU. The bus connection such as MVB, Ethernet or CAN service is available per car builder’ s request. In order to achieve the high reliability of the EDCU, all the electrical key components are imported;
• The sensitive edge system is part of electrical system. When the sensitive edge installed on the door panel hits the obstacle during the closing, the door panel will start to open to avoid pinching. The function is achieved by two ways. The first is achieved by pressure wave switch which is connected to the door panel rubber seals and the second one is achieved by checking the current reaction from the motor.

  The door system consists of mechanical system and electrical system. Mechanical system includes door operator, door shaft and door panels. The electrical system includes power supply and controller. The door operator consists of driving mechanism, plugging mechanism, hanging mechanism, guiding mechanism, and locking & unlocking mechanism.
