Embodiment 1

[0033] refer to Figure 1-5 , the front end opening and closing mechanism 100 includes a vehicle head cover 1 and a driving mechanism 2 . Among them, such as figure 1 and figure 2 As shown, the vehicle head cover 1 includes a direction along the extension of the rail vehicle (for example figure 1 The front cover 11 and the rear cover 12 that are arranged front and rear in the direction shown by X in the middle. The drive mechanism 2 is connected between the vehicle head cover 1 and the rail vehicle body, and is used to drive the front cover 11 and the rear cover 12 to close or separate. The drive mechanism 2 includes a translation assembly 21 and a rotation assembly 22. The translation assembly 21 is connected to the front cover One of the front cover 11 and the rear cover 12 is used to drive it to translate, and the rotating assembly 22 is connected to the other one of the front cover 11 and the rear cover 12 and used to drive it to rotate.

[0034] The above-mentioned f...

Embodiment 2

[0058] Similar to the first embodiment, the front opening and closing mechanism 100 includes a vehicle head cover 1 and a driving mechanism 2 . The driving mechanism 2 is connected between the vehicle head cover 1 and the rail vehicle body, and is used to drive the front cover 11 and the rear cover 12 to close or separate. The driving mechanism 2 includes a translation assembly 21 and a rotation assembly 22 .

[0059] In this example, if Figure 6 As shown, the translation assembly 21 includes a first linear drive member 211, a first transmission rod 212 and a second transmission rod 213, the first linear drive member 211 includes a main body part 2111 and a movable part 2112 movably connected to the main body part 2111, The main body part 2111 can drive the movable part 2112 to move linearly along the preset direction. There is an angle between the preset direction and the horizontal direction. One end of the first transmission rod 212 is rotatably connected to the inner wall...

Abstract

The invention relates to the technical field of railway vehicles, and discloses a front end opening and closing mechanism for a railway vehicle. The front end opening and closing mechanism for a railway vehicle comprises a vehicle head cover and a driving mechanism, and the vehicle head cover comprises a front cover and a rear cover which are arranged front and back in the extending direction of the railway vehicle; the driving mechanism is connected between the vehicle head cover and the railway vehicle body and used for driving the front cover and the rear cover to be closed or separated, the driving mechanism comprises a translation assembly and a rotating assembly, the translation assembly is connected to one of the front cover and the rear cover and used for driving the front cover and the rear cover to translate, and the rotating assembly is connected to the other one of the front cover and the rear cover and used for driving the other one to rotate. The front end opening and closing mechanism for a railway vehicle is simple in structure, high in flexibility and convenient to use.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a front end opening and closing mechanism for rail vehicles. Background technique [0002] For traditional rail vehicles, such as high-speed trains and bullet trains, in order to achieve reconnection or separation between vehicles, opening and closing mechanisms are usually installed at both ends of the vehicle to facilitate return rescue. [0003] The existing opening and closing mechanism usually includes two openable and closable hoods, which are divided into left and right parts along the longitudinal symmetrical plane of the vehicle body and connected to the end of the vehicle body through a rotating member. When the two hoods are combined and closed, the head of the vehicle is closed and has a streamlined appearance, the running resistance of the vehicle is low and debris can be prevented from entering; when the two hoods are opened separately, the internal coupler an...
