Abstract

The invention discloses a vehicle door and a driving device thereof. The vehicle door comprises a door beam, a door frame, a linear motor and a door body, wherein the door beam is fixedly arranged inthe door frame, and the linear motor comprises a stator and a mover; the stator is fixedly arranged on the door beam, and the door body is fixedly arranged on the mover; the moving direction of the mover is consistent with the extending direction of the door beam. The vehicle door and the driving device thereof disclosed by the invention directly have the advantages that the door body fixedly connected with the linear motor is driven by the linear motor to open and close the door, the structure is simple, the action is direct, the running resistance is small, the weight is light, and the wearis small.

Description

technical field [0001] The invention relates to the vehicle field, in particular to a vehicle door and a driving device thereof. Background technique [0002] Most of the side doors of passenger compartments of current subway trains adopt a built-in door structure, and the door wing is controlled by a rotating motor through a transmission device to complete the door opening and closing action. [0003] Since the rotating motor, transmission device, control device, locking device, etc. constitute a complex door opening and closing system, frequent opening and closing of the door will easily lead to door failure, affecting train operation and safety. Contents of the invention [0004] The embodiment of the invention provides a vehicle door and a driving device thereof. In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. This summary is not an overview, nor is it intended to identify key / critical elemen...
