Description

Technical Field

[0001] The utility model relates to the technical field of rail transit vehicle doors, and particularly relates to a driver's cab door with a hidden armrest and a rail transit vehicle. Background Art

[0002] At present, a large number of manual hinge door structures are adopted for the driver's cab doors of rail trains. In order to facilitate the driver to board the vehicle, an armrest is generally arranged on the outside of the vehicle body. There are problems with the armrest setting of the existing driver's cab doors: 1) The armrest area is located outside the vehicle body, which will cause poor appearance consistency of the whole vehicle and a decline in appearance quality. 2) There is a depression in the vehicle body in the armrest area. During the running of the train (especially a high-speed train), air flow impact will be caused in this area, resulting in an increase in wind noise and affecting the comfort inside the vehicle; at the same time, the armrest may also cause adverse phenomena such as resonance due to the excitation of the air flow, affecting the normal use of the train.

Detailed implementation manners

[0027] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0028] A driver's cab door with a hidden armrest according to the present application, as shown in the figure, includes a vehicle body 1, a door leaf 2, an armrest assembly 3, a rubber strip assembly 4, a threshold 5, an intermediate lock stop 6, an upper lock stop 7, and a lower lock stop 8. The door leaf 2, the armrest assembly 3, the rubber strip assembly 4, the threshold 5, the intermediate lock stop 6, the upper lock stop 7, and the lower lock stop 8 are all installed on the vehicle body 1 through fasteners.

[0029] The door leaf 2 includes a door panel 201, an intermediate lock 202, a lower lock 203, a window glass 204, an upper hinge 205, a lower hinge 206, an upper lock tongue 207, an intermediate lock tongue 208, and a lower lock tongue 209. The door panel 201 is the main body of the door leaf 2, and it is connected to the vehicle body 2 through the upper hinge 205 and the lower hinge 206; the intermediate lock 202, the lower lock 203, the window glass 204, the upper lock tongue 207, the intermediate lock tongue 208, and the lower lock tongue 209 are all installed on the door panel 201; when the door is closed, the upper lock tongue 207, the intermediate lock tongue 208, and the lower lock tongue 209 are respectively lapped with the upper lock stop 7, the intermediate lock stop 6, and the lower lock stop 8 fixed on the vehicle body 2 to ensure that the door leaf 2 is constrained in the closed state and is in close contact with the rubber strip assembly 4 to achieve door sealing. The intermediate lock 202 and the lower lock 203 are linked, and operating either one can retract the upper lock tongue 207, the intermediate lock tongue 208, and the lower lock tongue 209 to unlock the door.

[0030] The armrest assembly 3 consists of a seat body 301, a handle 302, a rotating shaft 303, a torsion spring 304, a retaining ring 305, and a positioning detent 306. There are 2 seat bodies 301 in total, symmetrically arranged at both ends of the handle 302 and connected to the handle 302 through 2 rotating shafts 303; one torsion spring 304 is installed on each rotating shaft 303 to keep the handle 302 in the initial state. Notches are provided at both ends of the handle 302, and mechanical limits for the end state are provided at the front end 302 of the handle. When rotated by a certain angle under the action of an external force, the notch is limited by the positioning detent 306, keeping the handle 302 in the open position; after being subjected to an external force in the opposite direction and getting out of the limit of the positioning detent 306, the handle 302 can be fully reset by relying on the torsion of the torsion spring 304. When a person operates the armrest assembly 3 by hand outside the vehicle, the handle 302 rotates around the rotating shaft 303 to a certain angle and protrudes from the surface of the vehicle body 1. After letting go, it can be limited by the positioning detent 306 and kept in the open position; after boarding the vehicle, the person pushes the handle 302 by hand to get out of the limit of the positioning detent 306, and the handle 302 is reset under the action of the torsion of the torsion spring 304 and kept in the initial state, and its outer contour does not exceed the surface of the vehicle body 1.

[0031] There are two sets of armrest assemblies 3 in each set of doors, which are respectively installed on both sides of the entrance of the vehicle body 2 through the seat body 301. When the armrest assembly 3 is in the reset state, its outer contour does not exceed the surface of the vehicle body 2 and does not affect the normal opening and closing of the door leaf 2; after the door leaf 2 is closed, the armrest assembly 3 is not visible from outside the vehicle. When it is necessary to board the vehicle by using the armrest assembly 3 from outside the vehicle, first unlock and open the door through the middle lock 202 or the lower lock 203 on the door leaf 2, and pull the armrest assembly 3 to the open state. At this time, the handle 302 protrudes from the surface of the vehicle body 2, which is convenient for grasping and operation; after boarding the vehicle, the armrest assembly 3 can be manually reset.
