Description

Technical Field

[0001] The utility model relates to the field of rail transit vehicles, in particular to a novel integrated head cover for rail transit vehicles. Background Art

[0002] Rail transit refers to a type of transportation vehicle or transportation system in which operating vehicles need to travel on specific tracks. Common rail transit includes traditional railways (national railways, intercity railways and urban railways), subways, light rails and trams. With the popularization of public transportation, rail transit has become a means of transportation that we often take for daily travel or travel. In rail transit vehicles, the hood is an important component.

[0003] The existing hood generally includes a hood body, a body steel frame, a cab side panel and a cab roof panel. When assembled, the hood body, the cab side panel and the cab roof panel are respectively installed on the body steel frame, and the cab side panel, the cab roof panel and the body steel frame are all located inside the hood body. In the above structure, due to the existence of the body steel frame and the cab roof panel generally using thick fiberglass material, the overall weight is large, and there is a large gap between the hood body and the cab side panel during installation, which is not fitted, resulting in low space utilization rate of the driver's cab.

[0030] See also Figures 1 to 5 The utility model provides a new integrated hood for rail transit vehicles, including an integrated hood 1 and a cab side panel 2 and a cab roof panel 3 installed in the integrated hood 1. A U-shaped mounting groove 101 is formed on the inner wall of the integrated hood 1. The U-shaped mounting groove 101 extends from one side of the integrated hood 1 to the other side thereof. The profile of the cab side panel 2 is similar to the shape of the U-shaped mounting groove 101 and is fitted and fixed in the U-shaped mounting groove 101. The existing hood and cab side panel are connected by a body steel frame, which not only has a large overall weight, but also has gaps between the hood and the body steel frame and between the cab side panel and the body steel frame, resulting in low space utilization in the driver's cab. In this structure, the integrated hood and cab side panel are installed in a fitting manner, the body steel frame is removed, the overall weight is reduced, and there is no gap between the components, so the space utilization in the driver's cab is high.

Two cross bars 5 are arranged in parallel and at intervals on the inner wall of the integrated hood 1. Since the front end of the integrated hood is arc-shaped, the heights of the two cross bars are different. A plurality of hanging frames 4 are arranged at intervals along the straight line direction on the cross bars 5, and the cab roof 3 is fixedly connected to the hanging frames 4 by fasteners. An extension flange 201 is provided on the upper end of the cab side panel 2 extending outward, and the end of the cab roof 3 is abutted against the extension flange 201. This structure uses cross bars and hanging frames to install the cab side panels. Compared with the existing vehicle body steel frame installation, the overall weight is lighter and the connection is stable and reliable.

[0032] In some embodiments, Figure 3 and Figure 4As shown, the U-shaped mounting groove 101 includes side mounting grooves symmetrically arranged on both sides of the integrated hood 1 and a front mounting groove arranged at the front end of the integrated hood 1, and the two side mounting grooves are connected through the front mounting groove. The integrated hood 1 is provided with a front window 102 on the front side and side windows 103 on both sides; the cab side panel 2 is provided with through holes 202 at positions corresponding to the front window 102 and the side window 103.

[0033] In some embodiments, Figure 2 and Figure 3 As shown, a U-shaped horizontal plate 6 is installed in the integrated head cover 1 to facilitate the installation of other components.

[0034] In some embodiments, the cab roof 3 is an aluminum plate or an aluminum honeycomb structure, which is conducive to reducing the overall weight, and the thickness of the cab roof 3 is 4 mm. The total thickness of the integrated head cover 1 and the cab side panel 2 is 34 mm, and the thickness of the cab side panel 2 is 4 mm.

[0035] The same and similar parts between the various embodiments in this specification can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
