Embodiment 1

[0036] In a typical embodiment of the present invention, as figure 1 As shown, a pedal structure is proposed, which is suitable for rail vehicles such as subways and high-speed rails.

[0037] The pedal structure includes a pedal seat 1 and a pedal frame 2. The pedal seat is fixedly connected to the body of the rail vehicle, and the pedal seat and the pedal frame are connected by clamping, and between the pedal seat and the pedal frame The position of the pedal frame is limited by the anti-falling member.

[0038] In the pedal structure provided by the embodiment of the present invention, the use of fasteners such as bolts and nuts is eliminated by setting the pedal base and the pedal frame to be connected in a snap connection manner, which not only simplifies the installation structure, but also reduces the follow-up Repair work for fasteners.

[0039] The pedal seat 1 has an accommodating groove with an opening facing downward, that is, the pedal seat forms a C-shaped stru...

Embodiment 2

[0059] In this embodiment, a rail vehicle is provided, which includes the pedal structure and the vehicle body as described above, and the pedal seat is fixedly connected to the vehicle body.

Abstract

The invention discloses a pedal structure and a railway vehicle, and belongs to the technical field of railway vehicles. According to the technical scheme, the problem that existing pedals are connected through bolts and the like, so that the dismounting and mounting processes are complex is solved. The structure comprises a pedal seat and a pedal frame, wherein the pedal seat is provided with a containing groove with a downward opening, and the pedal frame is clamped in the containing groove of the pedal seat; two sides of the pedal frame are each provided with a stop structure, the side face of the containing groove is provided with a clamping block, and the stop structures and the clamping blocks are connected in a clamped mode so that the pedal base and the pedal frame can be fixedly connected.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, and in particular relates to a pedal structure and a rail vehicle. Background technique [0002] The statements herein merely provide background related to the present invention and do not necessarily constitute prior art. [0003] The floor of the passenger room of the rail vehicle is relatively high from the rail surface. In the absence of a platform, it will be difficult for the driver and maintenance personnel to get on the vehicle. The pedals installed on the lower part of the vehicle body can assist the driver and maintenance personnel to get on the vehicle. more convenient. [0004] However, the inventor found that the current pedal structures are all fastened and connected by bolts or rivets, and the process of disassembly and installation is complicated, and the fasteners may also need to be replaced due to failure, which increases maintenance work.
