Problems solved by technology

The above-mentioned device utilizes the gear rack arranged at the bottom of the pedal to cooperate with the shaft gear to realize the expansion and contraction of the pedal. Since the pedal needs to bear load, the rack and pinion are easily damaged under load and wear quickly during the transmission process, which makes the life of the device short.

Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] The concrete embodiment of a kind of automatic telescoping pedal assembly of the present invention, as Figure 1 to Figure 6 As shown, the automatic retractable pedal assembly includes a pedal 3, an air motor 4, a transmission shaft 11 and a guide device. The guide device includes two supports 1 arranged on both sides of the pedal 3 and extending in the front and rear directions. The two ends of the drive shaft 11 are supported by the support 1 fixed support. The air motor 4 and transmission shaft 11 are fixed on the front end of the support 1 . Considering that unexpected situations occur during the working process of the pedal 3, it is convenient to install and disassemble according to the actual installation position, and the upper end of the support 1 is used as the fixed end. In order to reduce the frictional resistance when the transmissio...

Abstract

The invention relates to an automatic telescopic pedal assembly and a vehicle using the same. The automatic telescopic pedal assembly comprises a pedal, a transmission shaft arranged under the pedal, a gear fixed to the transmission shaft, and a rack which is fixed to the bottom face of the pedal and meshes with the gear. The transmission shaft is further provided with at least one rolling body support part. The lower surface of the pedal is provided with a support face in rolling fit with the rolling body support part. During usage, the rolling body support part achieves a support function on the pedal, so that damage caused by too large loads of the gear and the rack is avoided, meanwhile, the abrasion speed of the gear and the rack is reduced, and the service life of the automatic telescopic pedal assembly is prolonged.

Description

technical field [0001] The invention relates to the field of vehicle equipment, in particular to an automatic retractable pedal assembly and a vehicle using the pedal assembly. Background technique [0002] In order to facilitate passengers to get on and off, pedals are generally provided at the door of the vehicle, especially for rail transit vehicles such as trains. Since there is a certain gap between the train and the platform, pedals need to be placed to avoid passengers stepping on the air. At present, the existing pedals are old-fashioned hand-release pedals. The old-fashioned hand-release pedals are not only cumbersome but also easy to hurt people. Since the old-fashioned hand-release pedals are separated from the door and controlled manually, automation cannot be realized. It takes too long for the crew to retract and release the pedals. Low. In order to solve the above problems, the Chinese patent with the publication number CN104875761A and the publication date o...
