Technical Field

[0002] Rail vehicles are vehicles that run on fixed tracks, primarily used to transport people or goods. These vehicles rely on the track for directional guidance and load-bearing capacity, and are typically used in rail transit systems such as railways, subways, light rail, and monorail.

[0003] Currently, rail vehicles primarily utilize crush boxes installed on the longitudinal beams. These absorb the impact energy through their own crushing deformation during a longitudinal collision. However, these devices are unrepairable and exhibit poor single-stage energy absorption. Furthermore, because crush boxes have a fixed energy absorption capacity, they require individual designs for vehicles with varying weights, resulting in a wide variety of specifications and limited versatility.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0025] Example

[0026] Depend on Figure 1-4 Provided is an adjustable rail vehicle collision energy absorbing mechanism, comprising a rail vehicle body 1;

[0027] A front main beam is formed on the rail vehicle body 1, and an adjustable collision energy absorbing mechanism 2 is installed on the front main beam;

[0028] The adjustable collision energy absorbing mechanism 2 includes a mounting beam 21 mounted on the main beam of the rail vehicle body 1, with support arms 22 integrally mounted on both ends of the mounting beam 21, and mounting seats 23 sleeved on the outside of the two support arms 22;

[0029] A U-shaped connecting pipe 24 is inserted on both sides of the mounting seat 23. A clamping plate 25 is slidably mounted on the outside of the two U-shaped connecting pipes 24. A rectangular cavity is formed between the clamping plate 25 and the mounting seat 23, and a plurality of collision energy absorbing plates 27 are inserted into the cavity.

[0030] A plurality of collision energy absorbing plates 27 are stacked and inserted between the clamping plate 25 and the mounting seat 23 and are surrounded by the two U-shaped connecting tubes 24 .

[0031] In this embodiment, in actual use, through the mutual movement coordination of multiple structures arranged in the adjustable collision energy absorbing mechanism 2, the arranged collapse energy absorbing plate 211 can cooperate with a number of stacked collision energy absorbing plates 27 to realize the collision energy absorption of the rail vehicle body 1; the collapse energy absorbing plate 211 and the stacked collision energy absorbing plates 27 can jointly form a multi-stage energy absorption mechanism, so that the impact energy received by the rail vehicle body 1 is gradually dissipated in a sequence, thereby ensuring the continuity of the energy absorption process.

[0032] Furthermore, by arranging a plurality of collision energy absorbing plates 27 stacked in a stepped manner on the adjustable collision energy absorbing mechanism 2, the impact load can be dispersed layer by layer, thereby improving the energy absorption capacity and avoiding premature failure of a single plate due to concentrated force; at the same time, through the clamping installation between the clamping plate 25 and the mounting seat 23, in actual installation, the number of collision energy absorbing plates 27 can be freely adjusted according to the needs of the rail vehicle body 1, and after the collision energy absorbing plates are damaged, they can also be repaired individually; by increasing or decreasing the number of collision energy absorbing plates 27, as well as adjusting the size and thickness, the energy absorption intensity and range can be flexibly adjusted, thereby realizing adjustable use of the energy absorption performance.

[0033] It should be noted that by configuring an adjustable number of collision energy absorbing plates 27, the energy absorption intensity and range can be flexibly adjusted according to actual operating requirements such as speed and load. In high-speed or heavy-load operating scenarios, the number of stacked collision energy absorbing plates 27 can be increased to improve the energy absorption capacity; in light-load or low-speed scenarios, the number can be reduced to reduce the weight of the vehicle; at the same time, the user can also change the thickness and length of a single collision energy absorbing plate 27 to adapt it to rail vehicle bodies 1 of different sizes.

[0034] Specifically, refer to Figure 2-3 Both ends of the four U-shaped connecting pipes 24 are threadedly connected with adjusting bolts 26, and a number of collision energy absorbing plates 27 are of different sizes and are distributed in a stepped manner as a whole.

[0035] In this embodiment, during use, the provided adjustment bolt 26 can be used to rotate and adjust the clamping distance between the clamping plate 25 and the mounting seat 23, so that the clamping plate 25 can cooperate with the mounting seat 23 to achieve clamping and installation of different numbers of collision energy absorbing plates 27.

[0036] Specifically, refer to Figure 2-3 One of the collision energy absorbing plates 27 on the side is integrally provided with positioning holes 28 at both ends, and a connecting beam 29 is inserted between the two positioning holes 28 set on the same side. The two ends of the two connecting beams 29 are commonly connected to the side plate 210.

[0037] In this embodiment, the user can insert the two connecting beams 29 in sequence at the upper and lower ends of the collision energy absorbing plate 27, and then insert the side panels 210 at the two ends of the connecting beams 29. In a preferred embodiment, corresponding screw holes are provided at the ends of the connecting beams 29 and the sides of the side panels 210. After the side panels 210 are inserted, the user can use suitable bolts to install the side panels 210 at the two ends of the connecting beams 29; at the same time, in order to ensure a stable connection, the two can also be installed by welding.

[0038] Specifically, refer to Figure 2 The two side panels 210 are arranged vertically and a crush energy absorbing plate 211 is installed on both sides thereof.

[0039] In this embodiment, the provided collapse energy absorbing plate 211 can be used to absorb the initial impact force, thereby achieving collision energy absorption of the impact force through its own collapse.

[0040] Furthermore, the user may install the crush energy absorbing plate 211 on the side surfaces of the two side plates 210 by welding.

[0041] Furthermore, the set crush energy absorbing plate 211 can be abutted against the front cover of the rail vehicle body 1. In the specific implementation, the set crush energy absorbing plate 211 is set near the front of the rail vehicle body 1, and the set mounting beam 21 is set near the middle section of the rail vehicle body 1.

[0042] Specifically, refer to Figure 3-4 The ends of the two mounting seats 23 are integrally mounted with a spindle seat 212 , and a threaded hole is opened on the spindle seat 212 .

[0043] In this embodiment, when the mounting beam 21 is installed at the front main beam of the rail vehicle body 1, the user can install the main shaft seat 212 on both sides of the mounting seat 23 at the front of the rail vehicle body 1 through bolts, and the preliminary installation of the adjustable collision energy absorption mechanism 2 can be achieved.

[0044] Specifically, refer to Figure 2-4 , a plurality of threaded holes are arranged in an array on the mounting beam 21 .

[0045] In this embodiment, the user can use an adapted bolt to install the mounting beam 21 on the front main beam of the rail vehicle body 1 , thereby cooperating with the mounting seat 23 to achieve stable installation of the adjustable collision energy absorbing mechanism 2 on the rail vehicle body 1 .

[0046] The adjustable rail vehicle collision energy absorption mechanism of the utility model:

[0047] Step 1: In actual use, when installing the adjustable collision energy absorbing mechanism 2 of the present application, the user first uses the appropriate bolts to install the mounting beam 21 on the front main beam of the rail vehicle body 1, and then installs the main shaft seats 212 on both sides of the mounting seat 23 on the front of the rail vehicle body 1 through bolts. At this time, the preliminary installation of the adjustable collision energy absorbing mechanism 2 can be completed;

[0048] Step 2: After the mounting base 23 and the mounting beam 21 are installed as a whole, the user can select the number of collision energy absorbing plates 27 according to the size of the rail vehicle body 1, and then stack several collision energy absorbing plates 27 in a stepped manner and insert them between the clamping plate 25 and the mounting base 23. After the collision energy absorbing plates 27 are inserted, the user adjusts the clamping plate 25 according to the stacking thickness of the collision energy absorbing plates 27, so that the clamping plate 25 cooperates with the mounting base 23 to achieve stable clamping of the collision energy absorbing plates 27;

[0049] Step 3: After the collision energy absorbing plate 27 is installed, the user can insert the two connecting beams 29 at the upper and lower ends of the collision energy absorbing plate 27 in sequence, and then insert the side panels 210 at both ends of the connecting beams 29. After the side panels 210 are inserted, they are installed at both ends of the connecting beams 29 by bolts or welding. At the same time, the crush energy absorbing plates 211 are installed on the sides of the two side panels 210 by welding.

[0050] Step 4: When the front end of the rail vehicle body 1 is hit, the impact force first acts on the crush energy absorbing plate 211. At this time, the crush energy absorbing plate 211 itself can absorb the initial impact force through the plastic deformation of the material through its own crush deformation, and then the remaining impact force is transmitted to the several collision energy absorbing plates 27 through the conduction of the connecting beam 29 and the side plate 210. The collision energy absorbing plates 27 set at this time are stacked and can disperse the impact load layer by layer, and absorb subsequent impact energy through the elasticity and plastic deformation of the collision energy absorbing plates 27. The superimposed design of the collision energy absorbing plates 27 can improve the energy absorption capacity and avoid premature failure of a single plate due to concentrated force.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
