In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0021] Please also read Figures 1 to 6 The anti-climbing energy absorption structure and the rail vehicle provided by the present invention are now described. The anti-climbing energy absorption structure comprises an energy absorption shell 1, a plurality of energy absorption blocks, and an anti-climbing assembly 3. The energy absorption shell 1 is arranged below the floor of the driver's cab, and a plurality of energy absorption blocks are arranged in the energy absorption shell 1 at intervals along the front-to-back direction. The anti-climbing assembly 3 penetrates the energy absorption shell 1 and the energy absorption blocks and extends to the front side of the energy absorption shell 1.

[0022] Compared with the prior art, the anti-climbing energy absorption structure provided in the present embodiment installs the anti-climbing component 3 and the energy absorbing block uniformly under the chassis of the driver's cab, which not only achieves effective weight reduction of the structure and saves the occupied space of the structure, but also realizes the dual functions of energy absorption and anti-climbing, meets the collision conditions of vehicles, and can effectively prevent the vehicle from climbing during the collision process, thereby improving the safety of vehicle operation.

[0023] In this embodiment, two anti-climbing energy absorbing structures are symmetrically arranged below the floor of the driver's cab. The two anti-climbing energy absorbing structures are arranged close to the two side walls of the vehicle respectively, and are used to prevent the vehicle from climbing the vehicle during a collision, and can effectively absorb the collision energy. The above arrangement is intended to improve the safety of the vehicle, especially the damage to the vehicle during an accidental collision. The anti-climbing component 3 can effectively prevent the relative climbing of the vehicle, and can also cooperate with the energy absorbing block to absorb part of the impact energy, reduce the impact of an accidental collision on the passenger compartment area of ​​the vehicle, and improve the safety of passengers.

[0024] The anti-climbing component 3 runs through the energy absorbing block, and the combination of the two can achieve the dual functions of anti-climbing and energy absorption. The above combined structure can effectively save installation space, facilitate the improvement of subsequent assembly efficiency, and ensure the safety of vehicle operation.

[0025] In some possible implementations, the above-mentioned characteristic energy absorbing shell 1 is adopted as follows Figures 1 to 6 Please also refer to Figures 1 to 6 The horizontal projection of the energy absorbing block is a trapezoid, and the area of ​​the horizontal projection of several energy absorbing blocks gradually increases from the front end to the rear end of the vehicle body.

[0026] In this embodiment, the horizontal projection of the energy absorbing block is a trapezoid, the length of the front side of the energy absorbing block is smaller than the length of the rear side, and the horizontal projection areas of the multiple energy absorbing blocks gradually increase from front to back, so that the multiple energy absorbing blocks form an effect of enhanced energy absorption from front to back, forming a cumulative energy absorption effect, which effectively attenuates the impact force during the vehicle collision and reduces the impact energy.

[0027] In some possible implementations, the above-mentioned characteristic anti-climbing component 3 is adopted as follows Figures 1 to 6 Please also refer to Figures 1 to 6 The anti-climbing assembly 3 includes a plurality of slidably connected telescopic rods 31. The front end of the telescopic rod 31 located at the front end is provided with an anti-climbing ruler 32. The anti-climbing ruler 32 extends along the width direction of the vehicle. The front end surface of the anti-climbing ruler 32 is provided with a plurality of meshing teeth 33 extending in the horizontal direction. The meshing teeth 33 are spaced apart in the up and down directions. The anti-climbing ruler 32 is spaced apart from the front end surface of the energy absorbing shell 1.

[0028] In this embodiment, the anti-climbing assembly 3 adopts a structure combining multiple telescopic rods 31 and an anti-climbing ruler 32. Multiple slidingly matched telescopic rods 31 can achieve free telescopic movement in the front-rear direction of the vehicle body without generating impedance.

[0029] During a vehicle collision, the impact is first reduced by the action of the car hook, and then the anti-climbing ruler 32 on the front side of the vehicle is meshed with the anti-climbing ruler 32 on the rear end of the rear-end vehicle. When the vehicle has a tendency to climb, the meshing action of the front and rear anti-climbing rulers 32 is used to make the telescopic rod 31 generate vertical impedance force to prevent the vehicle from climbing, and at the same time realize the longitudinal energy absorption of the vehicle. During the above process, the telescopic rod 31 can be freely extended and retracted without generating impedance force, until the rear end surface of the anti-climbing ruler 32 presses against the energy absorbing shell 1, causing the energy absorbing shell 1 to deform and act on multiple energy absorbing blocks in sequence, forming a step-by-step energy absorption effect. In the above process, the dual functions of anti-climbing and energy absorption are realized.

[0030] The meshing teeth 33 arranged on the front end surface of the anti-climbing ruler 32 extend in the horizontal direction, forming an inner concave structure between two adjacent meshing teeth 33, so that a meshing effect is formed between the two anti-climbing rulers 32, achieving a longitudinal energy absorption effect, and realizing the anti-climbing performance of the vehicle.

[0031] In some possible implementations, the above-mentioned characteristic energy absorbing shell 1 is adopted as follows Figures 1 to 6 Please also refer to Figures 1 to 6The energy absorbing shell 1 includes a side shell 11 and a rear bottom plate 12. The side shell 11 is connected to the inner wall of the driver's room outer cover 4. The side shell 11 has a side opening facing the outside of the vehicle body and a rear opening facing the rear side of the vehicle body. The side shell 11 is used to accommodate a plurality of the energy absorbing blocks. The rear bottom plate 12 is sleeved on the outer side of the rear end of the side shell 11. The rear end of the anti-climbing component 3 is connected to the inner wall of the rear bottom plate 12. The anti-climbing component 3 penetrates through a plurality of the energy absorbing blocks and the front end surface of the side shell 11 from back to front.

[0032] In this embodiment, the energy absorbing shell 1 is in the form of a combination of a side shell 11 and a rear bottom plate 12. The side opening of the side shell 11 faces the outside of the vehicle body. The side shell 11 can be connected to the inner wall of the driver's room outer cover 4 to form a cavity for accommodating the energy absorbing block. The rear side of the side shell 11 is used to install the rear bottom plate 12 so as to fix the rear end of the anti-climbing component 3.

[0033] A plurality of energy absorbing blocks are arranged in the cavity, and the rear bottom plate 12 can not only fix the rear end of the anti-climbing assembly 3, but also block the rear opening of the side shell 11, thereby ensuring the overall integrity of the energy absorbing shell 1 and realizing the effective installation of a plurality of energy absorbing blocks. It is convenient to set different numbers of energy absorbing blocks according to the requirements to meet the performance requirements of vehicle collisions at different speed levels.

[0034] Furthermore, an outwardly bent connecting flange 15 is provided at the edge of the side shell 11 , and the connecting flange 15 is connected to the inner wall of the driver's room outer cover 4 , thereby improving the reliability of the installation of the side shell 11 .

[0035] In some possible implementations, the characteristic energy absorbing block is used as follows Figures 1 to 6 Please also refer to Figures 1 to 6 There are three energy absorbing blocks, which are the first energy absorbing block 21, the second energy absorbing block 22 and the third energy absorbing block 23. The first energy absorbing block 21, the second energy absorbing block 22 and the third energy absorbing block 23 are arranged sequentially from front to back, and the anti-climbing component 3 passes through the third energy absorbing block 23, the second energy absorbing block 22 and the first energy absorbing block 21 sequentially from back to front.

[0036] In this embodiment, according to the energy absorption requirements of vehicle collision, the energy absorption block adopts a structure combining the first energy absorption block 21, the second energy absorption block 22, and the third energy absorption block 23 to achieve the effect of step-by-step energy absorption. Among them, the impedance of the second energy absorption block 22 is greater than the impedance of the first energy absorption block 21, and the impedance of the third energy absorption block 23 is greater than the impedance of the second energy absorption block 22, forming a gradually increasing impedance from front to back, ensuring the step-by-step energy absorption effect.

[0037] On this basis, the anti-climbing component 3 is sequentially arranged from the back to the front through the third energy absorbing block 23, the second energy absorbing block 22 and the first energy absorbing block 21, ensuring the energy absorption effect while achieving the anti-climbing effect. The above-mentioned structure is convenient for space layout, helps to save the installation space in the vehicle, and also reduces the overall weight of the structure, meeting the lightweight design of the vehicle.

[0038] In some embodiments, the above-mentioned characteristic energy absorbing shell 1 can be used as follows Figures 1 to 6 Please also refer to Figures 1 to 6 A first partition plate 13 and a second partition plate 14 are provided in the energy absorbing shell 1 . The first partition plate 13 is located between the first energy absorbing block 21 and the second energy absorbing block 22 , and the second partition plate 14 is located between the second energy absorbing block 22 and the third energy absorbing block 23 .

[0039] In this embodiment, the energy absorbing shell 1 is provided with a first partition 13 and a second partition 14. The first partition 13 can separate the first energy absorbing block 21 and the second energy absorbing block 22, and the second partition 14 can separate the second energy absorbing block 22 and the third energy absorbing block 23. When the energy absorbing shell 1 is pressed by the rear end surface of the anti-climbing ruler 32, it will deform. At this time, the impact force will be sequentially transmitted to multiple energy absorbing blocks, forming a step-by-step energy absorption effect.

[0040] Specifically, the first partition 13 and the second partition 14 are made of metal components, which can effectively separate two adjacent energy absorbing blocks, and realize the step-by-step energy absorption of multiple energy absorbing blocks. In the longitudinal energy absorption process, the first partition 13 and the second partition 14 can provide stable impedance for energy absorbing blocks of different force levels, realize the effect of gradually increasing impedance from front to back, ensure good energy absorption, and improve the safety of vehicle operation.

[0041] In some embodiments, the above-mentioned characteristic energy absorbing shell 1 can be used as follows Figures 1 to 6 Please also refer to Figures 1 to 6 The energy absorbing shell 1 is made of glass fiber reinforced plastics, and the first partition 13 and the second partition 14 are made of metal. The energy absorbing shell 1 is made of glass fiber reinforced plastics, has high structural strength, meets the installation stability of the energy absorbing block and the anti-climbing component 3, and realizes the lightweight design of the structure.

[0042] In some possible implementations, the first energy absorbing block 21, the second energy absorbing block 22 and the third energy absorbing block 23 are as follows: Figures 1 to 6 Please also refer to Figures 1 to 6 The first energy absorbing block 21, the second energy absorbing block 22 and the third energy absorbing block 23 have multiple cavities arranged at intervals. The single cavity of the first energy absorbing block 21 is larger than the single cavity of the second energy absorbing block 22, and the single air cavity of the second energy absorbing block 22 is larger than the single cavity of the third energy absorbing block 23.

[0043] In this embodiment, the energy absorption function of the above components is achieved by respectively setting a plurality of cavities in the first energy absorbing block 21, the second energy absorbing block 22 and the third energy absorbing block 23. The single cavity of the second energy absorbing block 22 is smaller than the single cavity of the first energy absorbing block 21, so that the energy absorption function of the second energy absorbing block 22 is greater than that of the first energy absorbing block 21, forming an energy absorption effect that is gradually enhanced from front to back, ensuring the sequential action of the energy absorbing structure and ensuring the stability of energy absorption.

[0044] Similarly, a single cavity of the second energy absorbing block 22 is smaller than a single cavity of the third energy absorbing block 23 , so that the energy absorbing effects of the first energy absorbing block 21 , the second energy absorbing block 22 and the third energy absorbing block 23 gradually increase from front to back.

[0045] On this basis, the cross-section of the cavity of the first energy absorbing block 21 and the second energy absorbing block 22 is a quadrilateral, and the cross-section of the cavity of the third energy absorbing block 23 is a hexagon, that is, a honeycomb structure. The third energy absorbing block 23 has a better energy absorption effect than the quadrilateral cavity cross-section of the first energy absorbing block 21 and the second energy absorbing block 22, thereby achieving a step-by-step improvement in the energy absorption effect.

[0046] By adjusting the cross-sectional shapes of energy-absorbing blocks of different energy-absorbing levels, multiple energy-absorbing blocks have impedances of different energy-absorbing levels, thereby adapting to the energy-absorbing requirements of collisions of different speed levels of vehicles. The third energy-absorbing block 23 with the largest impedance is placed behind the second energy-absorbing block 22 with a middle impedance, and the second energy-absorbing block 22 with a middle impedance is placed behind the first energy-absorbing block 21 with the smallest impedance, ensuring that the third energy-absorbing block 23 provides sufficient impedance for the second energy-absorbing block 22, and the second energy-absorbing block 22 provides sufficient impedance for the first energy-absorbing block 21, thereby ensuring that the energy-absorbing structure operates sequentially and ensures energy-absorbing stability.

[0047] Based on the same inventive concept, the embodiment of the present application also provides a rail vehicle, which includes an anti-climbing energy absorption structure. The anti-climbing energy absorption structure of the above vehicle uniformly installs the anti-climbing component 3 and the energy absorption block under the chassis of the driver's cab, which not only achieves effective weight reduction of the structure and saves the occupied space of the structure, but also achieves the dual functions of energy absorption and anti-climbing, meets the collision conditions of vehicles at different speed levels, and can effectively prevent the vehicle from climbing during the collision process, thereby improving the safety of vehicle operation.
