The current modes of operating passenger doors of a minibus are roughly divided into two types, namely manual operation and power source operation. Low-grade minibus cars use manual work to open and close passenger doors directly, and use folding doors in large quantities. These vehicle-type passengers are often equipped with a crew member in addition to the driver to assist the passengers in getting on and off the vehicle. With the advancement of technology, it has become a trend for power sources to operate passenger doors open and close. The inner swinging door is a product mainly used for realizing opening and closing actions of doors of large and medium-sized buses, and more passengers installed with power source operation of the minibus can be generated along with the promotion of consumption requirements and the development of the tourism industry.

At present, the driving device of the inner swing door on the market has two modes of pneumatic and electric, and is mainly applied to the opening and closing device of a passenger car door system. The pneumatic driving device is influenced by an air source and is unstable, the noise is high in the door opening and closing process, the transmission efficiency is low, and certain potential safety hazards exist; meanwhile, the air cylinder is driven to convert electricity into gas and convert the gas into kinetic energy, so that certain energy waste exists; the existing electric drive inner swing door has the disadvantages of complex internal structure, high manufacturing cost and low economic benefit. Therefore, we propose an inner swing door driving mechanism.
