An electronic differential electric double-leaf hanging sliding door applied to electric passenger cars

Abstract

The invention relates to the technical field related to automobiles, in particular to electronic differential electric double hanging sliding doors applied to an electric bus. The electric double hanging sliding doors output two different rotating speeds through two motors, and the two different rotating speeds are used for movement of two driven pieces, namely, sliding blocks, to realize door opening and closing functions, and the structure is simple; synchronous belts and the driven pieces are consistent in movement direction, the problem of pressure angle degradation during door opening and closing is avoided, the requirement for power of the motors is reduced, the cost is reduced, the safety is improved, the synchronous belts can drive the two driven pieces at the movement speeds which are identical in value and opposite in direction, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field related to automobiles, and more specifically relates to an electronic differential electric double-leaf hanging sliding door applied to electric passenger cars. Background technique [0002] The power control mechanism of the existing double-leaf public vehicle door system mainly has two modes: pneumatic inner swing door and electric inner swing door. Pneumatic inner swing door, that is, an ordinary rod cylinder drives the door shaft, and then the door shaft drives the door panel to swing in the door opening of the vehicle body. This type of inner swing door requires a clean and dry compressed air source. New energy pure electric public-purpose vehicles are becoming more and more popular. However, there are no air compressors, air tanks and other equipment to provide compressed air on such vehicles, so the passenger doors driven by compressed air are not suitable for pure electric public-purpose vehicles, w...

Problems solved by technology

A large part of the thrust F acts on the door shaft, causing pressure and friction on the bearing. This part of the thrust not only does useless work, but also causes wear on the parts on the door shaft.

In addition, during the door opening process, with the swing of the door, the pressure angle between the thrust F and the direction of the door movement speed V gradually decreases, while the thrust F remains constant, and the thrust of the push rod in the second half of the door opening movement If F is too large, the door will collide with the door frame, causing noise and affecting the service life of the door parts; the pressure angle of the inner swing door will also deteriorate during the door closing process.
