[0002] Rail vehicles refer to vehicles with dedicated tracks. The main components of a rail vehicle's frame are the driver's cab frame and the vehicle underframe. An energy-absorbing and anti-climbing device is installed at the front end of the vehicle underframe. By installing the anti-climbing and energy-absorbing device, the damage to the vehicle underframe during a collision can be reduced.

In order for the front beam to meet the support strength for the energy absorption anti-climb device, multiple reinforcing parts are usually provided on the other side of the front beam.

[0004] Because the reinforcing parts are numerous and scattered, they need to be welded to the front beam one by one, which makes the installation of the reinforcing parts time-consuming. Summary of the Invention

[0044] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] First, let me explain the terms used in this application:

[0047] Anti-climb energy absorption device: The anti-climb energy absorption device is a core component of the passive safety system of rail vehicles. It is mainly used to absorb kinetic energy during a collision and prevent vehicles from climbing over each other. Its core principle is to use plastic deformation mechanisms such as metal crushing, honeycomb structure buckling, or composite material delamination to convert impact kinetic energy into internal friction heat energy and deformation energy, achieving an energy dissipation rate of over 85%.

[0048] In existing technologies, to ensure the front beam provides sufficient support for the energy-absorbing anti-climbing device, multiple reinforcing components are typically installed on the other side of the front beam. Because these reinforcing components are numerous and widely distributed, they need to be welded to the front beam one by one, resulting in a time-consuming installation process.

[0049] To address the aforementioned problems, this application provides a vehicle chassis and vehicle, including a chassis body 100, a mounting structure 200, and a support structure 300. The mounting structure 200 is disposed at one end of the chassis body 100, with its first side adapted to connect to the driver's cab frame 10. The support structure 300 is connected to the second side of the mounting structure 200, with its first end adapted to correspond to the anti-climb energy-absorbing device 20, and its second end connected to the chassis body 100. The support structure 300 is connected to the driver's cab frame 10 via the mounting structure 200. While supporting the anti-climb energy-absorbing device 20, the support structure 300 also serves as a mounting platform for the driver's cab frame 10. Furthermore, by utilizing the support strength of the driver's cab frame 10, the support structure 300 meets the support strength requirements of the anti-climb energy-absorbing device 20. This satisfies the support strength requirements for the energy-absorbing anti-climb device while also offering the advantages of fewer and more concentrated parts.

[0050] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0051] On the one hand, such as Figure 1 As shown, this embodiment provides a vehicle chassis, including a chassis body 100, a mounting structure 200, and at least one support structure 300; wherein the mounting structure 200 is disposed at one end of the chassis body 100, and the first side of the mounting structure 200 is adapted to connect to the driver's cab frame 10; the support structure 300 is adapted to connect to the second side of the mounting structure 200, the first end of the support structure 300 is adapted to correspondingly install an anti-climb energy absorption device 20, and the second end of the support structure 300 is connected to the chassis body 100.

[0052] It should be noted that in this embodiment, the +X direction is the front direction of the vehicle chassis, the -X direction is the rear direction of the vehicle chassis, the +Y direction is the upper direction of the vehicle chassis, and the -Y direction is the lower direction of the vehicle chassis.

[0053] Specifically, the mounting structure 200 is located at the front end of the underframe body 100, and the upper side of the mounting structure 200 is adapted to connect to the driver's cab frame 10; the lower side of the mounting structure 200 is connected to the support structure 300; the front end of the support structure 300 is correspondingly equipped with an anti-climb energy absorption device 20, and the rear end of the support structure 300 is connected to the underframe body 100.

[0054] It should be noted that each anti-climb energy-absorbing device 20 is provided with a corresponding support structure 300. In this embodiment, there are two anti-climb energy-absorbing devices 20 and two support structures 300.

[0055] As an alternative implementation, in order to further increase the support strength of the anti-climb energy absorption device 20, the number of support structures 300 can be increased. Each anti-climb energy absorption device 20 can correspond to multiple support structures 300. The more support structures 300 corresponding to each anti-climb energy absorption device 20, the higher the support strength of the anti-climb energy absorption device 20, and the corresponding cost will also increase. The appropriate choice can be made according to actual needs.

[0056] Specifically, the mounting structure 200 is fixedly connected to the driver's cab frame 10 by welding or bolts, and the mounting structure 200 can also serve as the floor of the driver's cab. When the vehicle chassis collides, since the support structure 300 is connected to the driver's cab frame 10 through the mounting structure 200, the driver's cab frame 10 can provide a certain support force to the support structure 300, thereby strengthening the support strength of the support structure 300.

[0057] It should be noted that the main frame 100, mounting structure 200, and support structure 300 are all made of stainless steel. Stainless steel is corrosion-resistant due to the self-healing protective film formed by chromium, which makes it perform excellently in humid, chemical, and salt spray environments, greatly extending its service life. At the same time, stainless steel has high strength and hardness, capable of withstanding large loads and wear. Its surface is smooth, dense, and non-porous, making it extremely easy to clean. Stainless steel also possesses a modern and aesthetically pleasing silvery-white luster, and rich surface effects can be achieved through various processes. Furthermore, it has good resistance to high and low temperatures, adapting to extreme environments; it is easy to process and shape; and it is a 100% recyclable environmentally friendly material with low life-cycle costs and simple maintenance.

[0058] like Figure 2 As shown, the support structure 300 further includes a first support member 310 and at least two second support members 320. The two second support members 320 are disposed on opposite sides of the first support member 310, and the sidewalls of the second support members 320 away from the first support member 310 are inclined toward the first support member 310.

[0059] In this embodiment, there are two second support members 320, which are respectively disposed on opposite sides of the first support member 310. By adding second support members 320 on both sides of the first support member 310, the supporting pressure of the first support member 310 can be shared. Furthermore, by tilting the second support members 320 away from the side wall of the first support member 310 and towards the first support member 310, the resistance to shear force can be increased, and the supporting strength of the first support member 310 can be further increased during a vehicle collision.

[0060] Specifically, the two second support members 320 are symmetrically arranged on both sides of the first support member 310. The symmetrical arrangement can ensure uniform load distribution, avoid local overload, and improve structural stability and stiffness.

[0061] As an alternative implementation, the second support member 320 may also have four or six. Increasing the number of the second support members 320 can further share the supporting pressure of the first support member 310, thereby increasing the supporting strength of the support structure 300. However, the cost will also increase accordingly by increasing the number of the second support members 320. The number can be increased reasonably according to actual needs.

[0062] like Figure 3 and Figure 4 As shown, the support structure 300 can be prefabricated by welding the first support member 310 and the second support member 320 in advance. Prefabrication can reduce the installation time, improve work efficiency, and reduce defects caused during installation through standardized engineering production.

[0063] Furthermore, the first support member 310 is composed of two support frames 311 connected relative to each other. The two support frames 311 are welded together. The support frame 311 is formed by bending a steel plate twice in the same direction at different parts. The support frame 311 has the advantages of low cost and simple manufacturing. Furthermore, support frames 311 of different sizes can be obtained by selecting steel plates of different sizes and bending them at different parts. Moreover, the production and design costs are low, and no additional mold opening costs are required.

[0064] It should be noted that the two support frames 311 are connected by welding, and as an alternative implementation method, they can also be connected by adhesive.

[0065] Furthermore, the second support member 320 includes two first side plates 321 and a second side plate 322. The two first side plates 321 are arranged opposite to each other, and the second side plate 322 is arranged between the two first side plates 321. The second side plate 322 is inclined toward the first support member 310.

[0066] It should be noted that both the first side plate 321 and the second side plate 322 are connected by welding.

[0067] As an alternative implementation, the first side plate 321 and the second side plate 322 can also be connected by adhesive bonding.

[0068] Specifically, at least one first through hole 323 is provided on the first side plate 321; at least one second through hole 324 is provided on the second side plate 322. By providing the first through hole 323 and the second through hole 324, the weight of the first side plate 321 and the second side plate 322 can be directly reduced, and the consumption of raw materials can be reduced.

[0069] It should be noted that by reasonably setting the positions of the first through hole 323 and the second through hole 324, the stress in the part can be dispersed, thereby achieving a certain energy absorption effect.

[0070] like Figure 5 As shown, the vehicle chassis further includes at least one reinforcing structure 400, one side of which is connected to the second end of the support structure 300, and the other side of which is connected to the chassis body 100.

[0071] To further increase the support strength of the support structure 300, its volume can be increased. When the projection of the support structure 300 in the vehicle chassis direction is greater than the cross-section of the vehicle chassis, the second end of the support structure 300 is connected to the chassis body 100. In this case, the support force provided by the vehicle chassis to the support structure 300 is limited. To ensure the support strength of the support structure 300, a reinforcing structure 400 is provided. The reinforcing structure 400 abuts against the exposed part of the second end of the support structure 300, thereby maximizing the support effect of the support structure 300.

[0072] It should be noted that the upper part of the reinforcing structure 400 is connected to the base frame body 100, and the front of the reinforcing structure 400 is connected to the second end of the supporting structure 300.

[0073] In one possible implementation, the chassis body 100 includes a chassis body 110 and a chassis end beam 120; the chassis end beam 120 is disposed at the end of the chassis body 110 and is connected to the support structure 300.

[0074] The base frame end beam 120 is connected to the support structure 300 by bolts or welding. The base frame end beam 120 provides support to the support structure 300.

[0075] Specifically, the base frame body 110 is a square frame structure with an opening on one side, and the base frame end beam 120 is set at the opening of the square frame.

[0076] Furthermore, the base frame body 100 also includes at least two diagonal bracing plates 130. One side of the diagonal bracing plate 130 is connected to the base frame end beam 120, and the other side of the diagonal bracing plate 130 is connected to the base frame body 100. By setting the diagonal bracing plates 130, deformation of the base frame end beam 120 can be prevented.

[0077] In this embodiment, the diagonal bracing plate 130 is a triangular plate, which has the advantages of being stable and not easily deformed.

[0078] Since there are two support structures 300, there are four diagonal bracing plates 130. Each support structure 300 corresponds to two diagonal bracing plates 130. The bottom frame end beam 120 is provided with two diagonal bracing plates 130 on the other side of each support structure 300. By setting the diagonal bracing plates 130, the stability of the bottom frame end beam 120 is further increased. In the event of a collision, the support strength of the bottom frame end beam 120 can be increased due to the diagonal bracing plates 130, preventing the bottom frame end beam 120 from deforming.

[0079] Furthermore, the base frame body 100 also includes at least one first reinforcing plate 140, which is disposed between two diagonal bracing plates 130.

[0080] By setting the first reinforcing plate 140, the supporting effect of the diagonal brace plate 130 can be further increased, and the deformation of the base frame end beam 120 during a collision can be further prevented.

[0081] In one possible implementation, the vehicle chassis further includes a plurality of second reinforcing plates 500, which are evenly spaced along the length of the vehicle chassis on the mounting structure 200.

[0082] Specifically, the second reinforcing plate 500 is a strip plate that extends along the width of the vehicle chassis.

[0083] By setting a second reinforcing plate 500 on the mounting structure 200, the overall strength of the mounting structure 200 can be increased, enabling the mounting structure 200 to meet the installation requirements of the driver's cab frame 10, and also further increasing the support strength of the support structure 300.

[0084] It should be noted that the second reinforcing plate 500 is evenly spaced along the length of the vehicle chassis in the mounting structure 200, and has a multi-level buffer design. In the event of a collision, it can achieve the effect of layered energy dissipation. The mounting structure 200 without the second reinforcing plate 500 can deform and absorb energy, while the mounting structure 200 with the second reinforcing plate 500 can have better bending resistance.

[0085] On the other hand, a vehicle includes a vehicle chassis comprising any of the above.
