Embodiment Construction

[0012] Control attached figure 1 , The driving mechanism is composed of a transmission mechanism, a self-locking mechanism, a lifting mechanism, an anti-pinch device, and a manual switching mechanism. Wherein the transmission mechanism is made up of motor 1, pinion 2, duplex gear 3, bull gear 4, door pump output shaft 5; The lifting mechanism has multi-thread 9 and multi-head nut 10; the anti-pinch device has anti-pinch nut 11, anti-pinch switch S, and anti-pinch switch S is connected to the controller. The controller is mainly composed of a single-chip microcomputer (model 16C57); manual switching The mechanism includes a motor output shaft 8, a blade paddle 12, a blade groove 13, a connecting rod 15, and a shift fork 14.

[0013] With reference to accompanying drawing 2, wherein pinion 2 is installed on the motor output shaft, pinion 2 meshes with the big tooth of double gear 3, and the small tooth of double gear 3 meshes with big gear 4. When the motor 1 is working, the p...

Abstract

The present invention relates to an electric (automatic) driving mechanism mounted in the large and medium coach and bus. Said mechanism is formed from transmission mechanism, self-locking mechanism, lifting mechanism, squeeze prevention and manual switching mechanism. Said invented electric (automatic) driving mechanism can be used for controlling bus door, and its structure is simple and is reliable.

Description

technical field [0001] The invention relates to an electric (automatic) driving mechanism installed on a large and medium-sized passenger car. The utility model belongs to the technical field of passenger vehicles. Background technique [0002] The existing electric driving mechanism used on the passenger car door can be divided into two types: vertical type and horizontal type. Its structure is relatively complex, bulky, simple in appearance, and the control system is all controlled by strong electricity. It is far from meeting the needs of the development of modern luxury passenger cars. Contents of the invention [0003] The object of the present invention is to address the above-mentioned defects, and propose a dual-gear mechanism with a lifting device and a manual device for its transmission parts. Lock, anti-pinch and other functions. The technical solution of the present invention: its structure is composed of a transmission mechanism, a self-locking mechanism, a...
