It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0039] In order to enable those skilled in the art of this technical field to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0040] As Figures 1 to 7 shown, in this embodiment, an anti-collision structure for a rail vehicle is provided. The anti-collision structure is disposed at the connection between the on-vehicle mounting structure 1 and the vehicle body platform 2 and is used to realize the fixed connection between the on-vehicle mounting structure 1 and the vehicle body platform 2. The anti-collision structure includes a plurality of stop blocks 3 and a plurality of stop strips 4. The plurality of stop blocks 3 are fixed to the vehicle body platform 2 and correspond to the side walls of the on-vehicle mounting structure 1. The fixing method of the stop blocks 3 to the vehicle body platform 2 can be welding or bolt connection, etc., to ensure the connection strength between the two. The plurality of stop strips 4 are respectively fixed on different side walls of the on-vehicle mounting structure 1, and each stop strip 4 protrudes horizontally from the side wall where it is located.

[0041] Furthermore, the on-vehicle mounting structure 1 may have four side walls, namely a front side wall 11, a left side wall, a right side wall 13, and a rear side wall 12. Among them, the front side is the side where the vehicle faces the traveling direction, the rear side is the side opposite to the traveling direction, the front side wall 11 and the rear side wall 12 are oppositely arranged; the left side wall and the right side wall 13 are oppositely arranged and are located between the front side wall 11 and the rear side wall 12. On this basis, the plurality of stop blocks 3 respectively correspond to the four side walls of the on-vehicle mounting structure, that is, the plurality of stop blocks 3 are distributed on the lower sides of the four side walls of the on-vehicle mounting structure 1, and stop strips 4 are provided on all four side walls of the on-vehicle mounting structure 1.

[0042] Please refer to Figure 4 , the stop block 3 includes a flat portion 302 and a stop portion 301. The side wall of the on-vehicle mounting structure 1 is fixed to the flat portion 3 by mounting bolts 5, and the upper surface of the flat portion 302 is in contact with the bottom surface of the side wall of the on-vehicle mounting structure 1, so that the on-vehicle mounting structure 1 and the stop block 3 have a more stable contact surface; among them, a base can be provided at the bottom of the side wall of the on-vehicle mounting structure 1 to facilitate the fixed connection with the flat portion by mounting bolts 5. In this embodiment, the base can also be regarded as a part of the side wall.

[0043] In any one of the stoppers 3, the stopping portion 301 protrudes vertically from the planar portion 302, and a stopping groove 303 opening towards the stopping strip 4 is provided in the protruding portion of the stopping portion 301. It should be noted that in this embodiment, the stopping groove 303 on the stopping portion 301 opening towards the stopping strip 4 means that among the stopper 3 and the stopping strip 4 corresponding to the same side wall of the vehicle-mounted mounting structure 1, the stopping portion 301 of the stopper 3 is provided with a stopping groove 303 opening towards the stopping strip 4. On this basis, since the stopping strip 4 protrudes from the side wall where it is located in the horizontal direction, the protruding portion of the stopping strip 4 can be inserted into the stopping groove 303 and is limited and clamped vertically. At the same time, the stopping strip 4 remains in contact with the groove wall of the stopping groove 303, making it have a stable clamping effect.

[0044] Among them, the stopping strip 4 can be an integral structure with the side wall where it is located, or a fixed connection relationship formed by welding, bolt connection, etc. It can be seen that on the one hand, the vehicle-mounted mounting structure 1 of the present application is fixedly connected to the planar portion 302 through the mounting bolt 5, and on the other hand, it can be limited and clamped by the stopping strip 4 and the stopping portion 301. And each side wall can realize the connection of the mounting bolt 5 with the corresponding stopper 3 and the limiting clamping of the stopping strip 4 and the stopper 3, so as to ensure the overall fixing effect of the vehicle body mounting structure.

[0045] Combining the above embodiments, the anti-collision structure of the present application is used to connect the vehicle-mounted mounting structure 1 and the vehicle body platform 2. The anti-collision structure includes stoppers 3 and stopping strips 4. A plurality of stoppers 3 are fixed on the vehicle body platform 2 and correspond to different side walls of the vehicle-mounted mounting structure 1. Each stopper 3 includes a stopping portion 301 and a planar portion 302 that fits the bottom surface of the side wall of the vehicle-mounted mounting structure 1. The stopping strips 4 are provided on different side walls of the vehicle-mounted mounting structure 1. The stopping strips 4 are vertically limited and clamped with the stopping grooves 303 provided on the stopping portions 301. When the rail vehicle collides, the cooperation between the stoppers 3 and the stopping strips 4 can, on the one hand, respectively inhibit the deformation and movement of each side wall of the vehicle-mounted mounting structure 1, and on the other hand, transfer the collision load of the vehicle-mounted mounting structure 1 to the vehicle body platform 2, avoiding the collision load concentrating at the mounting bolts 5, resulting in the fracture of the mounting bolts 5, thereby preventing the failure of the mounting bolts 5 and ensuring the running safety of the vehicle.

[0046] Further, the stopper 3 includes a first stopper 31, a second stopper 32 and a third stopper 33, and the stopping strip 4 includes a first stopping strip 41, a second stopping strip 42 and a third stopping strip 43 distributed on different side walls of the vehicle-mounted mounting structure 1. Please refer to Figure 2 and Figure 3; In this embodiment, the first stop block 31 and the first stop strip 41 are classified as the longitudinal stop mechanism. The multiple first stop blocks 31 in the longitudinal stop mechanism are distributed transversely and correspond to the front side wall 11 of the vehicle-mounted mounting structure 1. The first stop strip 41 is arranged on the inner wall surface of the front side wall 11, and the first stop strip 41 can be in limit snap connection with the stop groove 303 on the first stop block 31; when a vehicle collision occurs, the mounting bolt 5 and the longitudinal stop mechanism act together to transfer the instantaneous huge collision load to the vehicle body platform 2. The longitudinal stop mechanism shares the load of the mounting bolt 5, avoiding the bolt fracture failure caused by the instantaneous huge load. At the same time, the stop groove 303 of the first stop block 31 provides a downward anti-overturning force, preventing the vehicle-mounted mounting structure 1 from detaching from the first stop block 31 and falling onto the track.

[0047] In this embodiment, the second stop block 32 and the second stop strip 42 are classified as the transverse stop mechanism. The multiple second stop blocks 32 in the transverse stop mechanism are distributed longitudinally and correspond to the left side wall and the right side wall 13 of the vehicle-mounted mounting structure 1 respectively. The two second stop strips 42 are arranged on the inner wall surfaces of the left side wall and the right side wall 13 respectively, and the second stop strip 42 can be in limit snap connection with the stop groove 303 on the second stop block 32; when a lateral or non-frontal longitudinal collision of the vehicle generates a transverse collision load, the mounting bolt 5 and the transverse stop mechanism act together to transfer the instantaneous huge collision load to the vehicle body platform 2. The transverse stop mechanism shares the load of the mounting bolt 5, avoiding the bolt fracture failure caused by the instantaneous huge load. At the same time, the stop groove 303 of the second stop block 32 provides a downward anti-overturning force, preventing the vehicle-mounted mounting structure 1 from detaching from the mounting structure and falling onto the track.

[0048] In this embodiment, the third stop block 33 and the third stop strip 43 are classified as the vertical stop mechanism. The multiple third stop blocks 33 in the vertical stop mechanism are distributed transversely and correspond to the rear side wall 12 of the vehicle-mounted mounting structure 1. The third stop strip 43 is arranged on the outer wall surface of the rear side wall 12, and the third stop strip 43 can be in limit snap connection with the stop groove 303 on the third stop block 33; when a vehicle collision occurs, the mounting bolt 5 and the vertical stop mechanism act together to transfer the instantaneous huge collision load to the vehicle body platform 2. The third stop block 33 provides an upward anti-overturning force for the vehicle-mounted mounting structure 1, avoiding the mounting bolt 5 of the vehicle-mounted mounting structure 1 from bearing excessive overturning force and causing bolt fracture failure, thereby preventing the vehicle-mounted mounting structure 1 from tipping backward and hitting adjacent vehicle-mounted equipment, avoiding greater losses and improving the collision safety of the vehicle.

[0049] The vertical stop mechanism, longitudinal stop mechanism, and lateral stop mechanism have the same or similar structures, and their structural lengths and installation quantities are adjusted according to the actual situation of the vehicle. The vertical stop mechanism and the longitudinal stop mechanism act together in the longitudinal collision scenario to ensure the collision safety of the vehicle. At the same time, the lateral stop mechanism provides a downward anti-overturning force to prevent the on-vehicle mounting structure 1 from detaching from the mounting structure and falling onto the track.

[0050] Among them, the above-mentioned longitudinal direction is the running direction of the rail vehicle or the length direction of the vehicle, the vertical direction is the vertical direction perpendicular to the track or the height direction of the vehicle, and the lateral direction is the direction perpendicular to the plane where the longitudinal and vertical directions are located or the width direction of the vehicle.

[0051] Please refer to Figure 6 and Figure 7 As shown in [Figure X] and [Figure Y], the stop portion 301 of the first stop block 31 is located inside the on-vehicle mounting structure 1. The first stop strip 41 protrudes horizontally from the inner wall surface of the front side wall 11, and the first stop strip 41 extends laterally on the front side wall 11 so that the first stop strip 41 is engaged with the stop grooves 303 of multiple first stop blocks 31; the stop portion 301 of the second stop block 32 is located inside the on-vehicle mounting structure 1. The first second stop strip 42 protrudes horizontally from the inner wall surface of the left side wall, and the second second stop strip 42 protrudes horizontally from the inner wall surface of the right side wall 13. The first second stop strip 42 and the second second stop strip 42 extend laterally so that the first second stop strip 42 is engaged with the stop grooves 303 of multiple second stop blocks 32, and the second second stop strip 42 is respectively engaged with the stop grooves 303 of multiple second stop blocks 32; the stop portion 301 of the third stop block 33 is located outside the on-vehicle mounting structure 1. The third stop strip 43 protrudes horizontally from the outer wall surface of the rear side wall 12, and the third stop strip 43 extends laterally on the rear side wall 12 so that the third stop strip 43 is engaged with the stop grooves 303 of multiple third stop blocks 33. Through the above method, it can be ensured that each stop block 3 can be limited and engaged with the corresponding stop strip 4, ensuring that the stop block 3 and the stop strip 4 can transmit the collision load and preventing the installation bolts 5 from breaking and failing.

[0052] Please refer to Figure 4, in any one of the stoppers 3, the stop groove 303 is a horizontal groove-like structure; while the stop strip 4 is a horizontal plate-like structure. The lower groove wall of the stop groove 303 is coplanar with the upper surface of the planar portion 302. In the direction from the bottom of the stop groove 303 to the opening, the upper groove wall of the stop groove 303 is inclined upward. By the above method, when the vehicle-mounted mounting structure 1 is assembled with the vehicle body platform 2, it can be slid into the stop groove 303 from the front end to the rear end. The second stop strip 42 needs to slide into the stop groove 303 of the second stopper 32 first, and the lateral stop mechanism plays a role in restricting and positioning the vehicle-mounted mounting structure 1. Among them, since the upper groove wall of the stop groove 303 is inclined upward and the lower groove wall of the stop groove 303 is flush with the upper surface of the planar portion 302, it is convenient for the second stop strip 42 to enter the stop groove 303 of the second stopper 32. On this basis, by pushing the vehicle-mounted mounting structure 1 from front to back, the first stop strip 41 can enter the stop groove 303 of the first stopper 31, and the third stop strip 43 can enter the stop groove 303 of the third stopper 33.

[0053] Furthermore, after the vehicle-mounted mounting structure 1 is assembled in place, the stop portion 301 of the first stopper 31 can abut against the inner wall surface of the front side wall 11 of the vehicle-mounted mounting structure 1, the stop portion 301 of the second stopper 32 can abut against the inner wall surface of the left side wall or the right side wall 13 of the vehicle-mounted mounting structure 1, and the stop portion 301 of the third stopper 33 can abut against the outer wall surface of the rear side wall 12 of the vehicle-mounted mounting structure 1, thereby improving the limit and restraint effect of the stopper 3 on the vehicle-mounted mounting structure 1 and ensuring the stability of the vehicle-mounted mounting structure 1. At the same time, by using the abutting relationship between the stop portion 301 and the side wall of the vehicle-mounted mounting structure 1, the load borne by the vehicle-mounted mounting structure 1 can be further transmitted to the stopper 3, further avoiding the fracture and failure of the mounting bolt 5.

[0054] The anti-collision structure of the rail vehicle in this application suppresses the deformation and movement of the vehicle-mounted mounting structure 1 in the longitudinal, lateral, and vertical directions by each stop mechanism. The longitudinal stop mechanism, the lateral stop mechanism, and the vertical stop mechanism respectively integrate the bolt mounting function of the vehicle-mounted mounting structure 1. The vehicle-mounted mounting structure 1 is connected to the vehicle body platform 2 through the mounting bolt 5, and the mounting bolt 5 is fastened to each stopper 3. The structure design is compact, improving the utilization rate of the vehicle body platform 2 for the vehicle-mounted space.

[0055] This application effectively improves the safety of vehicle collisions. The newly designed stop mechanism integrates the bolt mounting function of the vehicle-mounted mounting structure 1, effectively avoiding the risk of failure of the mounting bolt 5 of the vehicle-mounted mounting structure 1, thereby eliminating or greatly reducing the impact of the collision shock on the adjacent vehicle-mounted mounting structure 1, with good social and economic benefits. At the same time, the stopper 3 is designed as a card slot structure. On the one hand, it can effectively improve the safety of vehicle collisions. On the other hand, the inclined opening stop groove 303 is convenient for the stop strip 4 to enter the stop groove 303 during equipment installation, improving the convenience and maintainability of the assembly of the mounting structure.

[0056] The present application also provides an orbital vehicle, which includes a car body platform 2, an on-vehicle mounting structure 1, and the above-mentioned anti-collision structure for orbital vehicles. Among them, the upper structure of the car body platform 2 is divided into a collision resistance area 6, a deformable control area 7, and a safety area 8. Please refer to Figure 8 ; The collision resistance area 6 is the on-vehicle mounting structure 1 located at both ends of the vehicle. The on-vehicle mounting structure 1 in this area directly bears the impact load of the collision, mainly absorbs the energy generated by the collision through deformation, and allows large plastic deformation to occur. Therefore, high-voltage equipment and power equipment (such as battery packs, diesel engines, converter cabinets, etc.) are avoided to be set in this area.

[0057] The core of the anti-collision of this orbital vehicle is to ensure that the mounting bolts 5 of the on-vehicle mounting structure 1 in the collision resistance area 6 do not all fail, and to avoid excessive extrusion into the equipment rooms in adjacent areas. Therefore, the above-mentioned anti-collision structure for orbital vehicles can be set at the collision resistance area 6 to fix the on-vehicle mounting structure 1 in the collision resistance area 6 on the car body platform 2, solving the risk of the failure of the mounting bolts 5 of the on-vehicle mounting structure 1 during the collision. Its structural design is simple, effective, and highly feasible.

[0058] The deformable control area 7 is the on-vehicle mounting structure 1 adjacent to the collision resistance area 6. The on-vehicle mounting structure 1 in this area does not undergo plastic deformation or only undergoes minor plastic deformation, and it is necessary to ensure the structural integrity of key equipment.

[0059] The safety area 8 is located between the two deformable control areas 7 on both sides. The impact load generated by the collision cannot be transmitted to the on-vehicle mounting structure 1 in this area to ensure the collision safety of the structure in the safety area 8.

[0060] A sufficient buffer gap 9 needs to be reserved between the collision resistance area 6 and the deformable control area 7 to avoid excessive extrusion due to deformation. The buffer gap 9 is sealed with an elastic sealing strip, which has a certain buffering effect on the collision load; sufficient buffer gaps 9 are reserved between the deformable control area 7 and the safety area 8, and between the safety area 8 and the safety area 8. When the collision energy is absorbed and relieved through the collision resistance area 6, the buffer gap 9, and the deformable control area 7, it is transmitted to the safety area 8 through the buffer gap 9. At this time, the collision energy has been greatly reduced, which is sufficient to ensure the collision safety of the on-vehicle mounting structure 1 in the safety area 8. The buffer gap 9 between the safety areas 8 plays a role in buffering micro-vibrations and ensures the integrity of the structure in the safety area 8.

[0061] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0062] In this article, specific examples are used to elaborate on the principles and implementation manners of the present application. The descriptions of the above embodiments are only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
