The embodiments of the present disclosure disclose a power-concentrated motor train unit car body and a rail train.

[0049] The core of the present disclosure is to provide a power-concentrated motor train unit car body and a rail train.

[0050] Please refer to Figures 1 to 4 .

[0051] The power-concentrated motor train unit car body provided by the present disclosure comprises a coupler mounting structure 4 arranged at the bottom of the front end of the car body, a coupler 1 arranged on the coupler mounting structure 4 along the running direction of the car body, an anti-climbing device 2 arranged at the front end of the car body, and an energy-absorbing deformation structure 7 arranged on the inclined surface of the front end of the car body. The coupler mounting structure 4 is provided with a coupler support structure 5 for supporting the coupler 1 and a sliding table structure 6 for assisting the coupler 1 to slide after collision.

[0052] Specifically, as shown in Figure 1 , the bottom of the front end of the car body is sequentially provided with the coupler mounting structure 4 and the coupler 1 arranged on the coupler mounting structure 4, the front end of the car body is provided with the anti-climbing device 2, and the front edge of the car body is provided with the energy-absorbing deformation structure. The above structures divide the main energy-absorbing area of the front end of the car body into the coupler energy-absorbing area, the anti-climbing device energy-absorbing area, and the common stroke area of the anti-climbing device and the car body (i.e. the energy-absorbing deformation structure 7 of the front edge of the car body), as shown in Figure 2 . When the vehicle collides, the coupler 1 and the anti-climbing device 2 absorb energy first, and as the collision further deepens, the energy-absorbing deformation structure 7 at the front end of the driver's cabin and the anti-climbing device 2 continue to crush and absorb energy, as shown in Figure 2 . The collision energy-absorbing sequence ensures the energy-absorbing requirements when the vehicle collides, improves the safety of the driver and passengers, and at the same time provides sufficient collision safety margin.

[0053] At the same time, in order to further ensure that the coupler can freely slide after shearing and limit the left and right movement, the sliding table structure 6 is arranged at the bottom of the coupler mounting structure 4, and the coupler support structure 5 is arranged for supporting the coupler 1 and the sliding table structure.

[0054] The power concentration motor train unit body and the track train pass through the cooperative work of the multiple components such as the coupler installation structure 4, the energy-absorbing deformation structure 7, and the coupler support mechanism 5, and when the vehicle collides, the coupler 1 and the anti-climber 2 first absorb energy, with the collision deepening, the coupler falls on the slide platform structure 6 to further retreat, and the energy-absorbing deformation structure 7 at the front end of the cab and the anti-climber 2 continue to crush and absorb energy, thereby ensuring the energy-absorbing requirement when the vehicle collides, improving the safety of the driver and passengers, and providing sufficient collision safety margin. Compared with the prior art, the vehicle body structure of the embodiment has been significantly improved in terms of collision resistance and can meet the EN15227 C-I type collision scene requirements.

[0055] The power concentration motor train unit body and the track train provided by the present application will be described in more detail below in combination with the drawings and specific embodiments.

[0056] In one specific embodiment, referring to Figure 4 and Figure 18 , the energy-absorbing deformation structure 7 includes a mounting frame, an energy-absorbing plate, and a support inclined beam connected between the mounting frame and the energy-absorbing plate; the mounting frame is fixedly arranged on the upper inclined surface at the front end of the vehicle body, the energy-absorbing plate is arranged obliquely on the front edge of the vehicle body, and the end of the energy-absorbing plate away from the vehicle body is connected to the mounting frame through the support inclined beam.

[0057] Specifically, the energy-absorbing deformation structure 7 includes a mounting frame, an energy-absorbing plate, and a support inclined beam connected between the mounting frame and the energy-absorbing plate. The mounting frame is a frame structure and is fixedly arranged on the upper inclined surface at the front end of the vehicle body by bolts or can be fixed by welding; the shape of the mounting frame can be a rectangular frame or a trapezoidal frame, etc. The energy-absorbing plate is arranged obliquely on the front edge of the vehicle body (such as structure a in Figure 18 The combined logic of the energy-absorbing deformation structure 7 is that the mounting frame is fixed on the vehicle body, the support inclined beam connects the mounting frame and the energy-absorbing plate to form a stable energy-absorbing structure. The energy-absorbing plate first bears the collision force during the collision, then transmits the force to the mounting frame and the vehicle body through the support inclined beam, and the unloading holes on the support inclined beam enable the inclined beam to crush and absorb energy in time when subjected to force, thereby improving the energy-absorbing effect.

[0058] On the basis of any one of the above embodiments, referring to Figure 18 , the inclined beam is uniformly provided with multiple unloading holes in the length direction.

[0059] Specifically, the support inclined beam is uniformly provided with multiple unloading holes (such as structure b in Figure 18 ) in the length direction. The unloading holes are circular holes, which can make the inclined beam more easily crush and absorb energy during the vehicle collision, and square holes, etc. can also be used.

[0060] Further, the outer edge of the energy-absorbing plate is an arc surface structure.

[0061] Specifically, the outer edge of the energy-absorbing plate is in an arc surface structure, which can better disperse the impact force, and can be replaced by a wavy outer edge, etc.

[0062] On the basis of any one of the above embodiments, with reference to Figures 11 to 15 , the coupler mounting mechanism 4 comprises a box body, which is divided into a rear box plate 43, a first side box plate 42, a vertical plate 41 and a second side box plate 44 around the box body, and a top plate 45 is provided on the rear box plate 43, the first side box plate 42, the vertical plate 41 and the second side box plate 44.

[0063] Specifically, the coupler mounting mechanism 4 comprises a box body surrounded by the rear box plate 43, the first side box plate 42, the vertical plate 41, the second side box plate 44 and the top plate 45, wherein the first side box plate 42, the second side box plate 44 and the rear box plate 43 are connected in a wedge-shaped structure, specifically as shown in structure b and structure c in Figure 12 , the above-mentioned wedge-shaped structure can effectively ensure the support strength of the coupler 1. The vertical plate 41 and the first side box plate 42 and the second side box plate 44 are connected in a bevel joint structure, which can effectively ensure that the coupler 1 is not in the middle of the vertical plate 41, and ensure that the upper and lower ends of the coupler 1 are uniformly stressed during shearing, wherein the coupler 1 is not sheared and the installation schematic diagram is shown in Figure 5 , and the post-shearing crushing schematic diagram of the vertical plate 41 is shown in Figure 6 .

[0064] Further, the vertical plate 41 comprises a plurality of shearing through slots and a transition structure provided on the plate body of the vertical plate 41, the plurality of shearing through slots are used for smooth shearing when the coupler is overloaded, and the transition structure is used for ensuring that the upper and lower forces are consistent when the coupler is sheared.

[0065] As shown in Figure 13 , the vertical plate 41 is mainly designed with shearing through slots and a transition structure, the shearing through slots are shown in Figure 13 structure a, the shearing through slots can be rectangular slot bodies, which can make the coupler 1 shear smoothly when the coupler 1 is overloaded, and the alternative features can be elliptical through slots, etc., the transition structure is shown in Figure 13 structure b, the transition structure can be a gradually changing inclined surface structure, which can ensure that the upper and lower forces are consistent when the coupler is sheared, and can be replaced by an arc transition structure, etc.

[0066] Further, the first side box plate 42 and the second side box plate 44 are oppositely arranged, and the first side box plate 42 and the second side box plate 44 each comprise a first support beam 421 and a second support beam 422 oppositely arranged, a wall plate is arranged between the first support beam 421 and the second support beam 422, and an included angle is formed between the first support beam 421 and the second support beam 422; a coupler retreat hole is formed on the rear box plate 43 to enable the coupler 1 to retreat smoothly when crushed.

[0067] Specifically, as shown inFigure 14 As shown, taking the first side box plate 42 as an example, it comprises a first support beam 421 and a second support beam 422 arranged oppositely, a wall plate is arranged between the first support beam 421 and the second support beam 422, and an included angle a is formed between the first support beam 421 and the second support beam 422. This included angle can make the vertical plate 41 bear force uniformly when it is supported, and the angle of the included angle can be adjusted according to actual design. The wedge-shaped structure (such as structure c in Figure 14 ) is adopted between the side box plate and the rear box plate 43, so as to ensure that the rear box plate 43 is wedged into the side box plate, and the inclined joint structure (such as structure b in Figure 14 ) is adopted for the side box plate, so as to ensure that the vehicle hook 1 bears force uniformly when it is sheared.

[0068] It should be noted that the first side box plate 42 and the second side box plate 44 can also adopt other frame structures to achieve similar support and uniform force bearing effects. The rear box plate 43 is provided with a vehicle hook retreat hole (as shown in structure c in Figure 15 ), which is a circular hole and can make the vehicle hook retreat smoothly when it is crushed, and can also be designed as a square hole or other shapes.

[0069] Further, the rear box plate 43 is mainly designed as a wedge-shaped groove, a wedge-shaped structure and a retreat hole. The wedge-shaped groove is shown in structure a in Figure 15 , which ensures that it is wedged with the side box plate, and the wedge-shaped structure is shown in structure b in Figure 15 , which ensures that it is wedged with the side box plate.

[0070] The combination logic of these components of the vehicle hook mounting structure 4 is that the top plate 45 covers the box plates around to form a closed box structure, which provides a stable mounting space for the vehicle hook. The shearing groove and the transition structure on the vertical plate 41 ensure that the vehicle hook 1 can be smoothly sheared and bear force uniformly when it is overloaded; the special structure of the first side box plate 42 and the second side box plate 44 ensures the support strength and uniform force bearing of the vehicle hook; and the vehicle hook retreat hole of the rear box plate 43 facilitates the retreat of the vehicle hook 1. The combination effect is to improve the stability and reliability of the vehicle hook mounting structure, and to ensure the normal work of the vehicle hook in the collision process.

[0071] On the basis of any one of the above embodiments, referring to Figures 16 to 17 , the vehicle hook support mechanism 5 comprises a support bracket arranged at the bottom and a connecting leg arranged on the support bracket. The support bracket is connected to the bottom of the vehicle hook mounting structure 4 through the connecting leg, and the slide table structure 6 is arranged on the support bracket and between the support bracket and the vehicle hook mounting structure 4. The support bracket is in a day-shaped structure, and the connecting leg is arranged in a figure-of-eight shape on both sides of the support bracket.

[0072] Specifically, the vehicle hook support mechanism 5 comprises a support bracket (as shown in structure a in Figure 16 ) arranged at the bottom and a connecting leg (as shown in structure b in Figure 16The support bracket 31 can be an H-shaped inclined plane structure welded by a cross beam, a longitudinal beam, an inclined beam and an angle brace, and an unloading hole is arranged on the support bracket 31 (for example, structure a in FIG. 6), so that the support bracket 31 can be crushed after a large collision of the vehicle to protect the driver's cabin and passengers, and other frame structures can also be used. The support bracket 31 is supported on the car hook mounting structure 4. The support bracket 31 is connected to the car hook mounting structure 4 through the connecting legs, and the slide table structure 6 is arranged on the support bracket and located between the support bracket and the car hook mounting structure. The support bracket is a day-shaped structure, which has good stability and can be replaced by a tian-shaped structure. The connecting legs are arranged in a total of two and are located on the two sides of the support bracket in an eight-shaped manner. The eight-shaped connecting legs can better disperse the force transmitted by the car hook. Other inclined angle setting modes can also be used. The car hook supporting mechanism 5 is designed as a U-shaped structure, and the day-shaped support bracket ensures that the car hook 1 can freely slide on the slide table structure 6 and be limited to move left and right after being crushed and sheared.

[0073] The combination logic of the car hook supporting mechanism 5 is that the support bracket is connected to the car hook mounting structure through the connecting legs to provide support for the car hook 1, and the slide table structure 6 can make the car hook 1 freely slide on the slide table structure 6 and be limited to move left and right after the car hook collides and is sheared, so as to ensure the stable retreat of the car hook.

[0074] On the basis of any one of the above embodiments, with reference to Figures 7 to 10 , the power concentration motor train unit body further comprises a car hook anti-falling structure 3. The car hook anti-falling structure 3 comprises a support frame 31 and a joist 32. The support frame 31 is supported on the car hook mounting structure 4. The joist 32 is located on the side of the support frame 31 away from the car hook mounting structure 4. The joist 32 is fixedly connected to the support frame 31 through hook-shaped overlapping bolts. An installation space for the car hook 1 to pass through is formed in the middle of the joist 32.

[0075] Specifically, the support frame 31 can be an H-shaped inclined plane structure welded by a cross beam, a longitudinal beam, an inclined beam and an angle brace, and an unloading hole (for example, structure a in FIG. 6) is arranged on the support frame 31, so that the support frame 31 can be crushed after a large collision of the vehicle to protect the driver's cabin and passengers, and other frame structures can also be used. The support frame 31 is supported on the car hook mounting structure 4. The support frame 31 is connected to the car hook mounting structure 4 through the connecting legs, and the slide table structure 6 is arranged on the support bracket and located between the support bracket and the car hook mounting structure. The support bracket is a day-shaped structure, which has good stability and can be replaced by a tian-shaped structure. The connecting legs are arranged in a total of two and are located on the two sides of the support bracket in an eight-shaped manner. The eight-shaped connecting legs can better disperse the force transmitted by the car hook. Other inclined angle setting modes can also be used. The car hook supporting mechanism 5 is designed as a U-shaped structure, and the day-shaped support bracket ensures that the car hook 1 can freely slide on the slide table structure 6 and be limited to move left and right after being crushed and sheared. Figure 8 Figure 7 The joist 32 is located on the side of the support frame 31 away from the car hook mounting structure 4. The joist 32 is fixedly connected to the support frame 31 through hook-shaped overlapping bolts (for example, structure a in FIG. 6). An installation space for the car hook to pass through is formed in the middle of the joist 32. The joist 32 is mainly designed as an upper hook-shaped overlapping structure (for example, structure b in FIG. 6). The lower part is a trapezoidal cross-section cross beam (for example, structure a in FIG. 6). The upper part and the lower part adopt a variable cross-section transition structure (for example, structure c in FIG. 6). This structure can bear a vertical load of not less than 300 kN, so as to ensure that the hook head of the car hook 1 is not uncoupled and the vehicle does not derail in abnormal working conditions of the vehicle, and other structures capable of bearing a large vertical load can also be used. Figure 9 Figure 9 Figure 10

[0076] ​​​​The combination logic of the car coupler anti-falling structure is that the support frame 31 is supported on the car coupler mounting structure 4, the joist 32 is connected with the support frame 31 through the hook type lap joint bolt, and the car coupler 1 passes through the mounting space of the joist 32. When the car coupler 1 is subjected to collision shearing, the car coupler anti-falling structure 3 can support the car coupler 1, prevent the car coupler 1 from falling to the track, and ensure the safety of the vehicle.

[0077] It should be noted that when the car coupler 1 is replaced by the automatic car coupler from the 105A type car coupler, the car coupler anti-falling structure 3 can not be installed.

[0078] The implementation principle of the power concentration motor train unit car body and the track train provided in the embodiment is as follows: the power concentration motor train unit car body in the embodiment cooperates with the car coupler mounting structure 4, the energy absorption deformation structure 7, the car coupler support mechanism 5, the car coupler anti-falling structure 3 and other components to absorb energy when the vehicle is subjected to collision, the car coupler 1 and the anti-climber 2 first absorb energy, the vertical plate 41 is sheared off as the collision deepens, the car coupler 1 further retreats, the energy absorption deformation structure 7 at the front end of the driver's room and the anti-climber 2 continue to crush and absorb energy, which ensures the energy absorption requirement when the vehicle is subjected to collision, improves the safety of the driver and passengers, and provides sufficient collision safety margin. Compared with the prior art, the car body structure in the embodiment has been significantly improved in terms of collision resistance, and can meet the requirements of the EN15227 C-I type collision scene.
