[0002] The cab frame is the main load-bearing part of the cab system, bearing the installation load of the cab hood, cab interior and cab electrical components. As the design of rail vehicles becomes more streamlined, the front face curvature of the cab hood is getting larger and larger. In order to ensure sufficient space inside the cab, the cab frame, especially the front side columns and escape door columns, are increasingly using bent aluminum alloy profiles.

[0003] like Figure 1 As shown, for aluminum alloy profiles with longer dimensions 01, a smaller bending radius will usually cause defects such as pits 02 and wrinkles on the surface of the profile.

[0046] In view of this, the core of the utility model is to provide a driver's cab frame, which can reduce the defects of bending of longer profiles and reduce the costs of tooling, labor and processing machinery.

[0047] Another core of the utility model is to provide a driver's cab.

[0048] Another core of the utility model is to provide a rail vehicle.

[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. For details, please refer to Figures 2 to 10 .

[0050] Please refer to Figure 2 The driver's cab frame disclosed in the embodiment of the utility model at least includes an escape door column 100 and a rear ring beam 500, and the escape door column 100 is fixed on the rear ring beam 500.

[0051] There are two escape door columns 100 for installing the escape door, and any one of the escape door columns 100 includes at least a first supporting column 101 and a second supporting column 102, and the first supporting column 101 and the second supporting column 102 are welded to form an arc structure.

[0052] Compared with the prior art, the driver's cab frame disclosed in the embodiment of the utility model reasonably and cleverly utilizes the welding process to make the escape door column 100 into one piece, which can not only meet the use requirements, but also reduce the bending size and small bending radius of aluminum alloy profiles, thereby greatly reducing the cost of tooling, labor and processing machinery.

[0053] It should be noted that there is a weld between the first support column 101 and the second support column 102. The position of the weld needs to be found out based on the static strength finite element calculation and the static strength test to find the position with less stress, so as to avoid the failure of the weld due to the load exceeding its own yield limit, so as to ensure the safe operation of the entire vehicle body and even the entire vehicle throughout its life cycle.

[0054] The embodiment of the utility model does not limit the specific structure of the escape door column 100. As long as the structure meets the use requirements of the utility model, it is within the protection scope of the utility model.

[0055] As one example, please refer to Figure 3 The escape door column 100 disclosed in the embodiment of the utility model includes a straight section 103, a first bent section 104 and a second bent section 105, wherein the straight section 103 is used to connect with the driver's cab floor, the second bent section 102 is connected with the rear ring beam 500, and the first bent section 104 is connected between the straight section 103 and the second bent section 104.

[0056] Among them, both the first bending section 104 and the second bending section 105 are arc-shaped structures. The radius of curvature of the first bending section 104 is R1, and 4500 mm ≤ R1 ≤ 4800 mm;

[0057] The radius of curvature of the second bending section 105 is R2, and 650 mm ≤ R2 ≤ 900 mm.

[0058] Among them, the weld is located on the first bending section 104.

[0059] With such a setting, not only can the strength and rigidity of the entire escape door column 100 be improved, but also the failure phenomenon of the weld due to bearing a load exceeding its own yield limit can be effectively avoided, thus ensuring the safe operation of the entire vehicle body and even the entire vehicle throughout its life cycle.

[0060] In order to further improve the overall strength of the entire driver's cab skeleton, the profile thickness of the escape door column 100 disclosed in the embodiment of the present utility model is 4 mm - 10 mm.

[0061] Among them, the length of the escape door column 100 is L, and L ≥ 2800 mm.

[0062] It should be noted that for details, please refer to Figure 4 , the profile section of the escape door column 100 is a "day"-shaped profile section.

[0063] As a further embodiment, please refer to Figure 5 , the driver's cab skeleton disclosed in the embodiment of the present utility model further includes a crescent plate mounting member 200. Among them, the crescent plate mounting member 200 is an arc-shaped structure imitating the escape door column 100.

[0064] Specifically, the crescent plate mounting member 200 includes a crescent plate 201 and a mounting seat 202. Among them, one end of the crescent plate 2012 is welded to the mounting seat 202, and the other end is movably connected to the escape door column 100. With such a setting, the distance between the mounting seat 202 and the driver's cab cowl is controlled within 25 mm, which can ensure that the mounting seat is closest to the driver's cab cowl to the greatest extent

[0065] Among them, the crescent plate 2012 is also provided with a connection hole for movably connecting with the escape door.

[0066] Please refer to Figure 6 , the mounting seat 202 includes an inner layer base 2021 and an outer shell 2022, and the outer shell 2022 wraps the inner layer base 2021.

[0067] Among them, the material of the inner base 2021 is aluminum alloy, and the material of the outer shell 2022 is carbon steel. Such a setting can not only realize welding with the crescent plate 201, but also meet the installation requirements of on-site drilling and tapping.
