[0002] Currently, the collision energy absorption design of high-speed trains generally meets the requirements of the standard EN15227C-I collision scenario. The vehicle collision energy absorption configuration meets the collision energy absorption requirements at a collision speed of 36 km / h. When the accident speed exceeds 36 km / h, it exceeds the vehicle's energy configuration, and can only absorb energy through the elasticity of the car body or by crushing the car body, which cannot meet the safety requirements of the driver and passengers.

[0003] In summary, how to address the high-speed collision safety requirements of power-centralized EMUs, while avoiding situations where vehicles exceed their energy capacity and can only rely on crushing the car body or elastic energy absorption, thus failing to meet the safety needs of drivers and passengers, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a power-centralized EMU car body and rail train, which effectively solves the high-speed collision resistance safety requirements of power-centralized EMUs and avoids the situation where, after the vehicle exceeds its energy configuration, it can only rely on crushing the car body or the car body elastically absorbing energy, which cannot meet the safety requirements of the driver and passengers.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance.

This application discloses a power-centralized EMU car body and rail train.

[0048] The core of this invention is to provide a power-centralized EMU car body.

[0049] Another core aspect of this invention is to provide a rail train, including the aforementioned power-centralized EMU car body.

[0050] Please refer to Figure 1 and Figure 2 .

[0051] The power-centralized EMU car body and rail train provided by the present invention include an energy storage box 1 disposed at the bottom of the front end of the car body, a coupler 2 disposed on the side of the energy storage box 1 away from the front end of the car body along the direction of travel of the car body, and at least one anti-climb device disposed at the front end of the car body; the energy storage box 1 includes a box body and an energy storage block 14 disposed in the box body, so that when the car body collides, the energy storage block 14 is crushed to absorb kinetic energy.

[0052] Specifically, the energy storage box 1 is located at the bottom of the front end of the vehicle body, the coupler 2 is positioned from the energy storage box 1 towards the direction of travel of the vehicle body, and the anti-climb device is located at the front end of the vehicle body. The energy storage box 1 contains an energy storage block 14, the structure of which is as follows: Figure 11 As shown, Figure 11 Structure a in the diagram is a guide hole for the movement of the coupler 2 in the energy storage block 14. The main energy absorption area is further divided into the coupler energy absorption area, the anti-creep device energy absorption area, and the shared energy absorption area of ​​the anti-creep device and the energy storage box (e.g., ...). Figure 18 As shown, the energy storage device is the energy storage box 1. When the vehicle body collides, the kinetic energy generated by the collision is transferred to the energy storage box 1, causing the energy storage block 14 to be crushed (as shown). Figure 5 , Figure 6 As shown, Figure 6 (Diagram showing crushing) The energy storage block 14 is used to crush kinetic energy, thereby absorbing the kinetic energy generated by the collision, improving the vehicle's collision resistance, and ensuring the safety of the occupants. In the event of a collision, the coupler 2, anti-climb device, and energy storage box 1 work together to effectively absorb the kinetic energy generated by the collision, ensuring the safety of the driver and passengers. The coupler 2 can withstand a certain amount of impact force in the initial stage of the collision, while the energy storage block 14 inside the energy storage box is crushed during the collision, further absorbing a large amount of kinetic energy, thus mitigating the impact of the collision on the vehicle body and the occupants.

[0053] The aforementioned power-centralized EMU car body, through the rational arrangement of components such as the coupler 2, anti-climb device, and energy storage box 1, achieves multi-stage absorption and dispersion of collision energy during a collision by having all components work together. The coupler 2 absorbs the impact force in the initial stage of the collision, while the energy storage block 14 in the energy storage box 1 absorbs a large amount of kinetic energy during the crushing process, ensuring the safety of the driver and passengers. Compared with existing technologies, it can effectively cope with high-speed collision accidents and provides strong protection for the safe operation of rail transit.

[0054] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the power-centralized EMU car body and rail train provided by the present invention.

[0055] In one specific implementation, reference is made to... Figure 2 and Figure 3The box body is formed by a bottom plate 16, a shearing plate 15, a top plate 13, a rear plate 17, and two upright plates 11. The shearing plate 15 and the rear plate 17 are arranged opposite each other and are located at the front and rear ends of the vehicle body in the direction of travel, respectively. Guide holes (such as...) are provided on the shearing plate 15 and the rear plate 17 for the coupler 2 to move. Figure 4 structure c in Figure 8 The structure c in and Figure 10 (b) The top plate 13 and the bottom plate 16 are arranged opposite each other and are located at the upper and lower ends of the vehicle body in the direction of travel, respectively; the two vertical plates 11 are arranged opposite each other and are located on the left and right sides of the vehicle body in the direction of travel, respectively.

[0056] Specifically, the housing is composed of a base plate 16, a shearing plate 15, a top plate 13, a rear plate 17, and two upright plates 11. Guide holes for the movement of the coupler 2 are provided on the shearing plate 15 and the rear plate 17. The base plate 16 is generally made of high-strength metal sheet, with a relatively thick structure and good load-bearing capacity. It can also be made of alloy material to further improve its strength and corrosion resistance. The shearing plate 15 is mainly designed with shear pin holes, which are used to ensure the installation of the shear pin 12 and the shearing process. The top plate 13 is also made of robust metal. It is arranged opposite to the base plate 16 and located at the upper and lower ends in the vehicle's direction of travel, providing stable top support for the energy storage box 1. A composite material top plate can also be used to reduce weight while maintaining strength. The rear plate 17 is primarily designed with guide hole structures. Two upright plates 11 are arranged opposite each other, located on the left and right sides of the vehicle's travel direction, respectively. The upright plates 11 are primarily designed with shear pin holes, which ensure the installation of the shear pin 12 and the shearing process. These components are assembled together by welding or bolting to form a robust box-shaped structure. In this structure, the various components cooperate with each other to ensure the stability and energy absorption effect of the energy storage box during a collision.

[0057] It should be noted that the installation diagram of the shear pin hole and shear pin 12 is as follows: Figure 12 As shown, Figure 4 Structure b in Figure 7 Structure b in Figure 9 All structures b in the diagram are shear pin hole structures.

[0058] Based on any of the above embodiments, refer to Figures 3 to 10 At least one set of guiding structures is provided between the top plate 13 and the bottom plate 16 and / or the two vertical plates 11 arranged opposite each other, so that the shear plate 15 crushes the energy storage block 14 in an orderly manner.

[0059] Each set of guide structures has at least one guide groove opened inside the energy storage box 1. The guide groove is opened along the vehicle's traveling direction. The shear plate 15 is provided with a first guide slider (e.g., ...) that cooperates with the guide groove. Figure 8Structure a). A second guide slider (such as) that mates with the guide groove is provided on the rear plate 17. Figure 10 Structure a in the text.

[0060] Specifically, the housing of this application has three guide slots (i.e. Figure 3 Structure a) is located on the top plate 13 and the two vertical plates 11 respectively. The guide groove is parallel to the extension direction of the coupler 2. The shearing plate 15 and the rear plate 17 are respectively provided with a first guide slider and a second guide slider that cooperate with the guide groove, so as to ensure that the shearing plate 15 moves in sequence according to the direction of the guide groove after shearing, and can crush the energy storage block 14 in an orderly manner.

[0061] It should be noted that the guide groove is generally formed on the inner wall of the energy storage box 1 (i.e., the vertical plate 11, the top plate 13, and the bottom plate 16, etc.) by machining. Its shape is usually rectangular or trapezoidal, providing good guiding performance. An arc-shaped guide groove can also be used to adapt to special collision situations. The first guide slider can be a block structure made of metal, fixed to the shear plate by welding or bolting, or it can be integrally formed. The function of the above-mentioned guiding structure is to enable the shear plate 15 to move orderly along a specific direction during collision, thereby ensuring that the energy storage block 14 is crushed evenly and improving energy absorption efficiency. When the coupler 2 is pushed by the collision force, the first guide slider will slide within the guide groove, guiding the shear plate 15 to accurately press against the energy storage block 14. The construction and function of the second guide slider are similar to the first guide slider, also to ensure the stability and guidance of the shear plate 15 during movement. It can use the same material and connection method as the first guide slider, or it can be adjusted according to actual conditions. When the shear plate 15 moves backward under the impact force, the second guide slider slides in the guide groove and works together with the first guide slider to ensure that the shear plate moves in the correct direction and accurately crushes the energy storage block 14.

[0062] In a specific embodiment provided in this application, multiple shear pin holes are provided at the connection points of the upright plate 11, the top plate 13, and the shear plate 15, and the shear pin holes are used to install shear pins 12.

[0063] Specifically, multiple shear pin holes are provided at the connection points of the upright plate 11, the top plate 13, and the shear plate 15. These holes are used to install shear pins 12. The shear pins 12 are typically made of high-strength alloy steel and possess specific shear strength. When the impact force reaches a certain value, the shear pin 12 will be sheared, allowing the shear plate 15 to continue moving and crush the energy storage block 14. Shear pins 12 with different shear strengths can also be used to adapt to different collision scenarios. The size and position of the shear pin holes are precisely designed according to the specifications and installation requirements of the shear pins 12 to ensure the installation accuracy and shearing effect of the shear pins 12. By setting the shear pins 12 and shear pin holes, graded absorption of collision energy can be achieved, allowing them to exert different energy absorption effects under different collision intensities.

[0064] Based on any of the above embodiments, refer to Figure 1 There are two anti-climb devices, and the two anti-climb devices are located on the upper sides of the coupler 2 respectively.

[0065] Specifically, anti-climb devices are generally made of high-strength metal materials, possessing a robust structure and good resistance to deformation. Composite material anti-climb devices can also be used to reduce weight. Their main function is to prevent vehicles from climbing each other during a collision, reducing injury to the vehicle body and occupants. Symmetrical arrangement of two anti-climb devices can better disperse the impact force and improve the anti-climbing effect. When a collision occurs, the anti-climb device first contacts the other vehicle, using its own deformation and blocking action to prevent the vehicles from climbing each other, creating favorable conditions for the subsequent energy absorption process.

[0066] Based on any of the above embodiments, please refer to Figures 13 to 17 The power-centralized EMU car body also includes a coupler anti-detachment structure, which includes a support frame 3 and a support beam 4. The support frame 3 is supported on the energy storage box 1; the support beam 4 is located on the side of the support frame 3 away from the energy storage box 1, and the hook-type lap bolts (such as...) connect the support beam 4 and the support frame 3. Figure 13 The structure a) is fixedly connected, and the middle of the support beam 4 forms an installation space for the coupler 1 to pass through.

[0067] Furthermore, the support frame 3 includes two opposing longitudinal beams 31 and a crossbeam 32 connecting the two longitudinal beams 31. Each longitudinal beam 31 has an inclined beam 33 on one side and an angle brace 34 on the other side. The longitudinal beams 31, the crossbeams 32 and the inclined beams 33 are all provided with multiple unloading holes.

[0068] Specifically, the support frame 3 is supported on the energy storage box 1. It consists of two opposing longitudinal beams 31 and a crossbeam 32 connecting the two longitudinal beams 31. Each longitudinal beam 31 has a diagonal beam 33 on one side and a corner brace 34 on the other side. These components are welded into an H-shaped inclined structure (e.g., Figure 14 Structure a), and unloading holes are added to all beams (such as...). Figure 15 (b) In the structure. The longitudinal beams 31, transverse beams 32, and diagonal beams 33 are generally made of high-strength steel, which has high strength and rigidity. The corner braces 34 play a role in strengthening the structural stability. Aluminum alloy materials can also be used to reduce weight. The function of the unloading hole is to allow the support frame 3 to crush and absorb energy after a major vehicle collision, protecting the safety of the vehicle's driver's cab and passengers.

[0069] The support beam 4 is located on the side of the support frame 3 away from the energy storage box 1. The support beam 4 is fixedly connected to the support frame 3 with hook-type overlapping bolts. An installation space for the coupler 2 to pass through is formed in the middle of the support beam 4. The support beam 4 is mainly designed with an upper hook-type overlapping structure (such as...). Figure 16 Structure b), the lower part is a trapezoidal cross-section beam (such as Figure 16 Structure a) in the middle adopts a variable cross-section transition structure for the upper and lower parts (such as... Figure 17 Structure c) in the text can withstand a vertical load of not less than 300kN, ensuring that the coupler 2 hooks do not detach under abnormal operating conditions of the vehicle, and that the vehicle does not derail or cause other dangerous situations.

[0070] It should be noted that when the coupler 2 is replaced by an automatic coupler instead of a 105A coupler, the anti-detachment structure of the coupler does not need to be installed.

[0071] The implementation principle of a power-centralized EMU car body in this embodiment is as follows: Through the rational arrangement of components such as the coupler 2, anti-climb device, energy storage box 1, and coupler anti-detachment structure, the components work together to achieve multi-level absorption and dispersion of collision energy during a collision. The coupler 2 withstands the impact force in the initial stage of the collision, the anti-climb device prevents vehicles from climbing each other, the energy storage block 14 in the energy storage box 1 absorbs a large amount of kinetic energy during the crushing process of the shear plate 15, and the coupler anti-detachment structure ensures that the coupler 2 does not detach under abnormal operating conditions. This significantly improves the collision resistance of the car body, ensuring the safety of the driver and passengers. Compared with existing technologies, it can effectively cope with high-speed collision accidents, providing strong protection for the safe operation of rail transit.

[0072] The rail train provided in this application includes the aforementioned power-centralized EMU car body. The remaining structures of the rail train are all prior art and will not be described in detail here.

The descriptions of the above embodiments are merely for the purpose of helping to understand the method and core ideas of the present invention.
