Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a collision avoidance structure and a vehicle. Background Technology

[0002] The rear bumper beam is an essential safety feature in every vehicle, typically consisting of a main beam and an energy-absorbing box. Its main function is to reduce the impact force received by the vehicle during a collision, thereby protecting the safety of the driver and passengers.

[0003] In related technologies, for ease of design, the energy-absorbing box of the rear bumper beam is welded to the main beam, and then the energy-absorbing box is connected to the vehicle body through a connecting frame, or the energy-absorbing box is connected to the rear longitudinal beam of the vehicle body by screws.

[0004] However, the connection strength between the energy-absorbing box and the main beam in the related technologies is not high and the effect of buffering impact is not good. Utility Model Content

[0005] This application provides a collision protection structure and vehicle that can be used to increase the strength of the collision protection structure and enhance the cushioning effect.

[0006] The first aspect of this application provides a collision avoidance structure, including a connecting frame, a collision avoidance beam, and an energy-absorbing component. The collision avoidance beam and the connecting frame are spaced apart. The collision avoidance beam has a through-hole extending through it in a first direction, forming two opposing openings on the beam. The energy-absorbing component is located between the collision avoidance beam and the connecting frame. One end of the energy-absorbing component is connected to the connecting frame, and the other end has a plug-in portion that plugs into the through-hole. The outer wall of the plug-in portion connects to the locations of the two openings on the collision avoidance beam.

[0007] According to the anti-collision structure of the first aspect of this application, a perforation is made in the anti-collision beam, and a plug-in part is provided on the energy-absorbing component. The plug-in part is inserted into the perforation of the anti-collision beam, and the plug-in part of the energy-absorbing component and the opening of the anti-collision beam are welded together to achieve the connection between the energy-absorbing component and the anti-collision beam. The energy-absorbing component of this application can be inserted into the anti-collision beam. In this way, the connection position between the energy-absorbing component and the anti-collision beam is where the structure of the energy-absorbing component and the anti-collision beam are superimposed, thereby increasing the strength of the connection position between the energy-absorbing component and the anti-collision beam. This makes it less likely for the energy-absorbing component and the anti-collision beam to deform when the anti-collision beam is impacted, ensuring the effect of buffering the impact force. In addition, the energy-absorbing component of this application is inserted into the through hole through the plug part. The plug part and the opening on the anti-collision beam are connected together. The two connection points between the plug part and the anti-collision beam are located at the beginning and end of the part of the plug part used to connect with the anti-collision beam. This not only increases the connection area between the energy-absorbing component and the anti-collision beam, resulting in a good connection effect and high connection strength, but also increases the buffer space to enhance the buffering effect and improve the energy absorption effect.

[0008] In one possible implementation, the energy-absorbing component includes a first body and a second body, which are connected. One end of the first body is connected to a connecting frame, and the other end of the first body is used to combine with the second body to form a plug-in portion. By setting the energy-absorbing component as two bodies, both bodies can be manufactured simultaneously during production, increasing production efficiency. Furthermore, manufacturing the energy-absorbing component separately is less difficult than manufacturing it as a whole.

[0009] In one possible implementation, the first main body includes a first intermediate plate and two first side plates, the two first side plates being connected to both ends of the first intermediate plate and located on the same side of the first intermediate plate; the second main body includes a second intermediate plate and two second side plates, the two second side plates being connected to both ends of the second intermediate plate and located on the same side of the second intermediate plate; the ends of the two first side plates away from the first intermediate plate are respectively connected to the ends of the two second side plates away from the second intermediate plate. This allows a cavity to be formed between the first and second main bodies, increasing the buffer space and thus enhancing the energy absorption effect.

[0010] In one possible implementation, the first intermediate plate includes a first intermediate end and a second intermediate end, with an included angle between the first intermediate end and the second intermediate end. The first side plate includes a first side end and a second side end. The first side ends of the two first side plates are respectively connected to the first intermediate end, and the second side ends of the two first side plates are respectively connected to the second intermediate end. An insertion portion is formed between the first side ends, the first intermediate end, the second side plate, and the second intermediate plate. By setting an included angle between the first intermediate end and the second intermediate end of the first intermediate plate, the space between the first intermediate plate and the second intermediate plate is increased, thereby increasing the buffer space and further enhancing the energy absorption effect.

[0011] In one possible implementation, the second intermediate plate has an outer edge protruding at the end away from the insertion part, and the connecting frame is also provided with a through hole. The outer edge is used to insert into the through hole and connect to the connecting frame. By providing the outer edge to connect with the connecting frame, the connection strength between the energy-absorbing component and the connecting frame can be enhanced.

[0012] In one possible implementation, a connector is also connected to the end of the first body away from the insertion part; the connector is used to connect to the connecting frame. By providing the connector, the energy-absorbing component can be connected to the connecting frame.

[0013] In one possible implementation, the energy-absorbing assembly further includes a first reinforcing member disposed on an end face of the energy-absorbing assembly along a second direction perpendicular to the first direction. One end of the first reinforcing member is fixed to the energy-absorbing assembly, and the other end is fixed to the crash beam. By providing the first reinforcing member, the connection strength between the energy-absorbing assembly and the crash beam in the second direction can be increased.

[0014] In one possible implementation, the first reinforcing member includes a first connecting end, a transition end, and a second connecting end connected in sequence. The first connecting end is connected to the energy-absorbing component, and the second connecting end is connected to the anti-collision beam. The first connecting end and the second connecting end of the first reinforcing member are respectively connected to the energy-absorbing component and the anti-collision beam, thereby connecting and fixing the energy-absorbing component and the anti-collision beam in a second direction.

[0015] In one possible implementation, both the first connecting end and the second connecting end are bent relative to the transition end, and the first connecting end and the second connecting end are bent toward the same side of the transition end. Adding a bent portion to the first reinforcing member can increase the strength of the first reinforcing member and improve its reinforcing effect.

[0016] In one possible implementation, a second reinforcing member is also included. This second reinforcing member is disposed on the end face of the energy-absorbing component along a third direction, perpendicular to both the third and second directions, as well as the first direction. One end of the second reinforcing member is fixed to the energy-absorbing component, and the other end is fixed to the crash beam. By providing the second reinforcing member, the connection strength between the energy-absorbing component and the crash beam in the third direction can be increased, thereby increasing the overall strength of the crash barrier structure.

[0017] In one possible implementation, the second reinforcing member includes a first connecting portion, a transition portion, and a second connecting portion connected sequentially. The first connecting portion is connected to the energy-absorbing component, and the second connecting portion is connected to the crash beam. The first and second connecting portions of the second reinforcing member are respectively connected to the energy-absorbing component and the crash beam, which increases the number of connection points between the energy-absorbing component and the crash beam, resulting in better connection strength between them.

[0018] In one possible implementation, an angle is formed between the first connecting portion and the transition portion, and an angle is also formed between the second connecting portion and the transition portion, causing the second reinforcing member to be bent. By bending the second reinforcing member, the axial strength of the second reinforcing member can be increased, thereby increasing the connection strength between the energy-absorbing assembly and the anti-collision beam.

[0019] In one possible implementation, the cross-sectional shape of the connector is square, circular, or trapezoidal, and the cross-sectional shape of the perforation matches that of the connector. The shapes of the connector and perforation can be customized according to specific circumstances, allowing for greater flexibility in their arrangement.

[0020] In one possible implementation, the crash beam includes a first beam and a second beam connected together. A perforation penetrates both the first and second beams, forming openings in both. The crash beam, comprising the first and second beams, can enclose a cavity to increase the buffer space and enhance energy absorption.

[0021] In one possible implementation, the connecting frame includes a frame and a connecting frame connected together, the connecting frame being used to connect the energy-absorbing components.

[0022] A second aspect of this application provides a vehicle, including a vehicle body and the aforementioned anti-collision structure. Attached Figure Description

Detailed Implementation

[0032] As described in the background section above, the connection strength between the energy-absorbing box and the main beam of the crash beam in related technologies is not high, resulting in poor buffering effect. This makes it easy for the main beam to deform when subjected to small impact forces, affecting its service life. Furthermore, due to the low impact buffering effect, the vehicle body is easily damaged during a collision. The main reason for the low connection strength between the energy-absorbing box and the main beam is that the energy-absorbing box and the main beam are generally fixed together by welding. In related technologies, the end of the energy-absorbing box is attached to the outer surface of the main beam, and the contact point between the energy-absorbing box and the outer surface of the main beam is welded. In this way, the energy-absorbing box is only welded to the outer surface of the main beam, resulting in a small welding area and too few welding points, thus leading to low strength between the energy-absorbing box and the main beam.

[0033] Based on the above problems, the anti-collision structure provided in this application has multiple connection points between the energy-absorbing component and the anti-collision beam, which can increase the connection area between the energy-absorbing component and the anti-collision beam, thereby increasing the connection strength between the energy-absorbing component and the anti-collision beam and ensuring that the vehicle body can better reduce the impact force when it encounters a collision.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Figure 1 This is a schematic diagram of an anti-collision structure provided in an embodiment of this application, wherein the X-axis is parallel to the first direction, the Y-axis is parallel to the second direction, and the Z-axis is parallel to the third direction, wherein the first direction, the second direction, and the third direction are perpendicular to each other.

[0036] See Figure 1 As shown, the first aspect of this application provides a collision protection structure that can be used on the rear frame of a vehicle. In some feasible ways, the collision protection structure includes a connecting frame 10, a collision beam 20, and an energy-absorbing component 30. The connecting frame 10 is used to connect the collision beam 20 and the energy-absorbing component 30, and the connecting frame 10 is used to connect the collision beam 20 and the energy-absorbing component 30 to the vehicle body. For example, the connecting frame 10 can be connected to the rear of the vehicle body.

[0037] The anti-collision beam 20 and the connecting frame 10 are spaced apart. When an external object is about to collide with the rear of the vehicle body, it will first come into contact with the anti-collision beam 20. The anti-collision beam 20 is used to prevent direct contact between the object and the vehicle body. The anti-collision beam 20 has a through hole 24 along the first direction. The through hole 24 forms two oppositely arranged openings on the two end faces of the anti-collision beam 20 in the first direction.

[0038] The energy-absorbing component 30 is connected between the anti-collision beam 20 and the connecting frame 10. The energy-absorbing component 30 is mainly used to buffer the impact force when the anti-collision beam 20 is subjected to a collision, thereby reducing the impact force transmitted to the vehicle body. One end of the energy-absorbing component 30 is connected to the connecting frame 10, and the other end of the energy-absorbing component 30 is provided with a plug-in portion 35. The plug-in portion 35 is plugged into the through hole 24. When the plug-in portion 35 is plugged into the through hole 24, a portion of its position corresponds to an opening on the anti-collision beam 20, and the outer wall of the plug-in portion 35 fits against the positions of the two openings on the anti-collision beam 20. The fitting portions of the plug-in portion 35 and the openings on the anti-collision beam 20 are connected. The plug-in portion 35 and the openings of the anti-collision beam 20 can be connected by adhesive or welding. In this embodiment, the connection of the plug-in portion 35 and the openings of the anti-collision beam 20 by welding is used as an example for explanation.

[0039] In this application, the cross-sectional shape of the plug portion 35 is not limited and can be square, circular or trapezoidal, and the cross-sectional shape of the through hole 24 is consistent with the cross-sectional shape of the plug portion 35.

[0040] In this embodiment of the anti-collision structure, the anti-collision beam 20 is connected to the connecting frame 10 via the energy-absorbing component 30, and the anti-collision structure is connected to the vehicle body via the connecting frame 10, thereby providing the vehicle body with the effect of reducing the impact force of a collision. In this application, a through hole 24 is provided in the anti-collision beam 20, and a plug-in part 35 is provided in the energy-absorbing component 30. The plug-in part 35 is inserted into the through hole 24 of the anti-collision beam 20, and the plug-in part 35 of the energy-absorbing component 30 and the opening of the anti-collision beam 20 are welded together to realize the connection between the energy-absorbing component 30 and the anti-collision beam 20. The energy-absorbing component 30 of this application can be inserted into the anti-collision beam 20. Thus, the connection point between the energy-absorbing component 30 and the anti-collision beam 20 is such that the structures of the energy-absorbing component 30 and the anti-collision beam 20 are superimposed, increasing the strength of the connection point and preventing deformation between them when the anti-collision beam 20 is impacted, thus ensuring the effectiveness of impact buffering. Furthermore, the energy-absorbing component 30 is inserted into the through hole 24 via a connector 35. The connector 35 and the opening on the anti-collision beam 20 are welded together, and the two welding points between the connector 35 and the anti-collision beam 20 are located at the beginning and end of the connection point. This not only increases the connection area between the energy-absorbing component 30 and the anti-collision beam 20, resulting in a better connection and higher connection strength, but also increases the buffer space, thereby enhancing the buffering effect.

[0041] It should be noted that the anti-collision beam 20 can be made of various materials, such as steel, aluminum alloy or thermoplastic plastic, depending on the actual needs. For example, aluminum alloy is generally used for anti-collision beams 20 in some high-end models, as it is lighter and helps to improve handling.

[0042] It should also be noted that the overall shape of the anti-collision beam 20 can be straight or curved. Regardless of whether the anti-collision beam 20 is straight or curved, in order to make the connection between the anti-collision beam 20 and the connecting frame 10 more stable, multiple connection positions are usually provided on the anti-collision beam 20 for connecting with the connecting frame 10. In this application, the location of the perforation 24 is the connection position of the anti-collision beam 20 for connecting with the connecting frame 10. It can be understood that the anti-collision beam 20 in this application is provided with multiple perforations 24, which are arranged at intervals along the second direction on the anti-collision beam 20. Each perforation 24 is used to install an energy-absorbing component 30, and the insertion part 35 of the energy-absorbing component 30 is inserted into the corresponding perforation 24.

[0043] Figure 2 This is an exploded view of an anti-collision structure provided in an embodiment of this application.

[0044] See Figure 2As shown, in some possible implementations, the energy-absorbing assembly 30 includes a first body 31 and a second body 32, which are connected together. One end of the first body 31 is connected to the connecting frame 10, and the other end of the first body 31 is used to combine with the second body 32 to form a plug-in portion 35.

[0045] Specifically, the first main body 31 can be connected to the connecting frame 10 by welding, or it can be detachably connected to the connecting frame 10 by a snap-fit ​​structure, fastening structure, or screws. When the first main body 31 is connected to the connecting frame 10 by welding, carbon dioxide is used as the shielding gas for welding. In this application, in order to facilitate the assembly and disassembly of the energy-absorbing component 30, the energy-absorbing component 30 is connected to the connecting frame 10 by screws.

[0046] In this application, the first body 31 and the second body 32 are connected together by welding. When welding the first body 31 and the second body 32, a protective gas such as carbon dioxide is used for protection.

[0047] In this application, to increase the buffer space, the energy-absorbing component 30 is hollow. Both the first main body 31 and the second main body 32 are plate-like structures. When the edges of the first main body 31 and the second main body 32 are welded together, an energy-absorbing cavity is formed between the first main body 31 and the second main body 32. Therefore, a partial energy-absorbing cavity structure is also formed inside the insertion part 35.

[0048] Specifically, in some feasible embodiments, the first body 31 includes a first intermediate plate 312 and two first side plates 311. The two first side plates 311 are connected to opposite ends of the first intermediate plate 312 and are located on the same side of the first intermediate plate 312. The two first side plates 311 can be welded to the first intermediate plate 312, or, as in this application, one end of the two first side plates 311 can be integrally formed to the first intermediate plate 312.

[0049] The two first side plates 311 have the same structure, and a predetermined angle is provided between the two first side plates 311 and the first intermediate plate 312, so that the two first side plates 311 are bent relative to the first intermediate plate 312.

[0050] It is worth mentioning that the two first side plates 311 can be arranged parallel or non-parallel. When the two first side plates 311 are parallel, the included angle between the first side plate 311 and the first intermediate plate 312 is greater than 0° and less than 180°, which needs to be determined according to the actual situation. When the two first side plates 311 are not parallel, the direction and angle of the bending of the two first side plates 311 relative to the first intermediate plate 312 can be equal or unequal. In this application, the example of the two first side plates 311 being parallel and the first side plate 311 being perpendicular to the first intermediate plate 312 will be used for illustration.

[0051] The second main body 32 includes a second intermediate plate 322 and two second side plates 321. The two second side plates 321 are connected to opposite ends of the second intermediate plate 322 and are located on the same side of the second intermediate plate 322. The two second side plates 321 can be welded to the second intermediate plate 322, or in this application, one end of the two second side plates 321 can be integrally formed to the second intermediate plate 322.

[0052] The arrangement between the two second side plates 321 and between the two second side plates 321 and the second intermediate plate 322 needs to be determined according to the arrangement between the first side plate 311 and the first intermediate plate. For example, in this application, the two first side plates 311 are parallel and the first side plate 311 is perpendicular to the first intermediate plate 312. Therefore, in this application, the two second side plates 321 are parallel and the second side plates 321 are perpendicular to the second intermediate plate 322.

[0053] It should be noted that when connecting the first main body 31 and the second main body 32, the first side plate 311 and the second side plate 321 need to be connected. Specifically, the distance between the two opposite end faces of the two first side plates 311 is set to be equal to the distance between the two opposite end faces of the two second side plates 321. In this way, the ends of the two second side plates 321 away from the second intermediate plate 322 can be placed between the ends of the two first side plates 311 away from the first intermediate plate 312, and the opposite end faces of the two second side plates 321 can respectively fit against the opposite end faces of the corresponding first side plates 311. After the overlapping part of the two first side plates 311 and the corresponding two second side plates 321 is structured, the connection between the first side plates 311 and the second side plates 321 is welded by welding.

[0054] By configuring the first main body 31 as a connection structure between two first side plates 311 and a first intermediate plate 312, the first main body 31 forms a semi-enclosed structure with an opening. The second main body 32 is configured as a connection structure between two second side plates 321 and a first intermediate plate 312, and the second main body 32 also forms a semi-enclosed structure with an opening. By setting the spacing between the two first side plates 311 and the two second side plates 321, when the openings of the first main body 31 and the second main body 32 are facing each other, the second side plates 321 can be inserted between the two first side plates 311 and welded together, thereby connecting and fusing the openings of the first main body 31 and the second main body 32, so that the first main body 31 and the second main body 32 enclose a hollow box structure. This increases the buffer space, giving the energy-absorbing component 30 a good buffering effect.

[0055] In this application, a plug-in portion 35 is formed between one end of the first side plate 311, the second side plate 321, the first intermediate plate 312, and the second intermediate plate 322 along the first direction. When the plug-in portion 35 is plugged into the through hole 24, the two first side plates 311 and the two second side plates 321 are arranged along the second direction, while the first intermediate plate 312 and the second intermediate plate 322 are arranged along the third direction.

[0056] See Figure 2 As shown, in some feasible ways, in order to increase the space of the energy absorption cavity inside the energy absorption assembly 30, the shape of the first intermediate plate 312 and the first side plate 311 can be set to change the shape of a part of the first main body 31, so that it can form a larger space when it is combined with the second main body 32.

[0057] Specifically, the first intermediate plate 312 includes a first intermediate end 3121 and a second intermediate end 3122. One end of the first intermediate end is connected to one end of the second intermediate end 3122. In this application, the first intermediate end 3121 and the second intermediate end 3122 are integrally formed and can be formed by bending the first intermediate plate 312 at the middle position, so that an included angle is provided between the first intermediate end 3121 and the second intermediate end 3122.

[0058] The end of the first intermediate end 3121 away from the second intermediate end 3122 is used to form a connector 35 with the first side plate 311, the second side plate 321, and the second intermediate plate 322. It should be noted that the first intermediate end 3121 is arranged parallel to the second intermediate plate 322, making the connector 35 square in shape. When the first side plate 311 is connected to the second side plate 321, the second intermediate end 3122 is bent away from the second intermediate plate 322. This causes the distance between the second intermediate end 3122 and the second intermediate plate 322 to gradually increase from the direction near the first intermediate end 3121 to the direction away from the first intermediate end 3121. Consequently, the cross-sectional area of ​​the energy-absorbing cavity formed between the second intermediate end 3122, the first side plate 311, the second side plate 321, and the second intermediate plate 322 gradually increases from the direction near the anti-collision beam 20 to the direction near the connecting frame 10.

[0059] To ensure structural compatibility between the first side plate 311 and the first intermediate plate 312, the first side plate 311 in this application includes a first side end 3111 and a second side end 3112. The first side ends 3111 of the two first side plates 311 are respectively connected to the first intermediate end 3121, and the second side ends 3112 of the two first side plates 311 are respectively connected to the second intermediate end 3122. An insertion part 35 is formed between the first side end 3111, the first intermediate end 3121, the second side plate 311, and the second intermediate plate 322.

[0060] Figure 3 This is another exploded view of the anti-collision structure provided in the embodiments of this application. Figure 4 This is another schematic diagram of the anti-collision structure provided in the embodiments of this application.

[0061] See Figure 2 and Figure 4 As shown, in order to increase the stability and anti-collision capability between the energy-absorbing component 30 and the anti-collision beam 20, in some feasible ways, the energy-absorbing component 30 also includes a first reinforcing member 33. The first reinforcing member 33 is used to increase the connection strength between the energy-absorbing component 30 and the anti-collision beam 20, so that the energy-absorbing component 30 is more stable relative to the anti-collision beam 20, and the anti-collision beam 20 is less likely to deform between the anti-collision beam 20 and the energy-absorbing component 30 when subjected to impact.

[0062] It should be noted that the first reinforcing member 33 can be disposed on the end face of the energy-absorbing component 30 along the second direction. One end of the first reinforcing member 33 is fixed to the energy-absorbing component 30, and the other end of the first reinforcing member 33 is fixed to the anti-collision beam 20. In this way, by providing the first reinforcing member 33, the connection strength between the energy-absorbing component 30 and the anti-collision beam 20 in the second direction can be enhanced.

[0063] It should also be noted that the energy-absorbing component 30 has two opposing end faces in the first direction. The first reinforcing member 33 can be provided on only one end face or on both opposing end faces.

[0064] In some possible implementations, the first reinforcement 33 includes a first connecting end 331, a transition end 333, and a second connecting end 332 connected in sequence, with the first connecting end 331 connected to the energy-absorbing assembly 30 and the second connecting end 332 connected to the anti-collision beam 20.

[0065] In this application, the first connecting end 331, the transition end 333, and the second connecting end 332 are integrally formed to increase the structural strength of the first reinforcing member 33. Furthermore, one end face of the first connecting end 331 can abut against the energy-absorbing component 30, and the edge of the first connecting end 331 is attached to the end face of the energy-absorbing component 30. The edge of the first connecting end 331 and the end face of the energy-absorbing component 30 can be fixedly connected by welding. Similarly, one end face of the second connecting end 332 can abut against the anti-collision beam 20, and the edge of the second connecting end 332 is attached to the end face of the anti-collision beam 20. The edge of the second connecting end 332 and the end face of the anti-collision beam 20 are fixedly connected by welding.

[0066] It is worth mentioning that the first connecting end 331 can be fixedly connected to the first side plate 311 of the first main body 31, or it can be connected to the second side plate 321 of the second main body 32. Alternatively, in this embodiment, the middle position of the first connecting end 331 can be placed across the connection between the first side plate 311 and the second side plate 321, with one end of the first connecting end 331 fixedly connected to the first side plate 311 and the other end of the first connecting end 331 fixedly connected to the second side plate 321. This can also increase the connection strength between the first side plate 311 and the second side plate 321.

[0067] In some feasible embodiments, both the first connecting end 331 and the second connecting end 332 are bent relative to the transition end 333, and the first connecting end 331 and the second connecting end 332 are bent toward the same side of the transition end 333. The directions of the bending of the first connecting end 331 and the second connecting end 332 relative to the transition end 333 are opposite, but the angles of bending of the first connecting end 331 and the second connecting end 332 relative to the transition end 333 can be equal or approximately equal. By bending the first connecting end 331 and the second connecting end 332 relative to the transition end 333, such that the first connecting end 331 is connected to the energy-absorbing component 30 and the second connecting end 332 is connected to the anti-collision beam 20, a triangular-like structure is formed between the first connecting end 331, the second connecting end 332, the transition end 333, the energy-absorbing component 30, and the anti-collision beam 20, thereby increasing the lateral anti-collision strength between the anti-collision beam 20 and the energy-absorbing component 30.

[0068] See Figures 2 to 4 As shown, in some feasible implementations, the energy-absorbing component 30 further includes a second reinforcing member 34, which is used to increase the stability and strength between the energy-absorbing component 30 and the anti-collision beam 20 in the third direction. Specifically, the second reinforcing member 34 is disposed on the end face of the energy-absorbing component 30 in the third direction. In this embodiment, the end faces of the energy-absorbing component 30 in the third direction are the opposite end faces of the first intermediate plate 312 and the second intermediate plate 322. Therefore, the second reinforcing member 34 can be connected to the end face of the first intermediate plate 312 opposite to the second intermediate plate 322, or the second reinforcing member 34 can be connected to the end face of the second intermediate plate 322 opposite to the first intermediate plate 312. This application uses the example of the second reinforcing member 34 being disposed on the end face of the second intermediate plate 322 opposite to the first intermediate plate 312 for illustration.

[0069] It should be noted that one end of the second reinforcing member 34 is fixed to the second intermediate plate 322 of the energy-absorbing component 30, and the other end of the second reinforcing member 34 is fixed to the anti-collision beam 20. This can increase the compressive strength of the anti-collision beam 20 and the energy-absorbing component 30 in the third direction, and increase the anti-collision strength of the anti-collision beam 20 and the energy-absorbing component 30 in the third direction.

[0070] In some possible implementations, the second reinforcement 34 includes a first connecting portion 341, a transition portion 343, and a second connecting portion 342 connected in sequence. The first connecting portion 341, the transition portion 343, and the second connecting portion 342 are integrally formed. The first connecting portion 341 is connected to the energy-absorbing component 30, and the second connecting portion 342 is connected to the anti-collision beam 20.

[0071] In this embodiment, the first connecting part 341 is welded to the second intermediate plate 322 of the energy absorption assembly 30, and the second connecting part 342 is welded to the anti-collision beam 20.

[0072] In some feasible implementations, an angle is formed between the first connecting portion 341 and the transition portion 343, and an angle is also formed between the second connecting portion 342 and the transition portion 343. Furthermore, the bending direction of the first connecting portion 341 relative to the transition portion 343 is opposite to the bending direction of the second connecting portion 342 relative to the transition portion 343, thus bending the second reinforcing member 34. By bending the second reinforcing member 34, its strength can be increased, further enhancing the connection strength between the energy-absorbing assembly 30 and the anti-collision beam 20 in the third direction, making the energy-absorbing assembly 30 and the anti-collision beam 20 less prone to deformation in the third direction.

[0073] It should be noted that multiple second reinforcing members 34 may be provided on the second intermediate plate 322, and the multiple second reinforcing members 34 are arranged at intervals along the second direction.

[0074] For example, two adjacent second reinforcing members 34 can also be connected together by a connecting plate to increase the overall strength.

[0075] See Figures 1 to 3 As shown, in some possible implementations, the end of the first body 31 away from the insertion part 35 is also connected to a connector 36, which is used to connect the connecting frame 10. It should be noted that the connecting frame 10 may include a frame body 11 and a connecting frame 12 connected together. The frame body 11 and the connecting frame 12 can be fixed together by screws or welded together. The connecting frame 12 is used to connect the connecting frame 10 on the energy absorption assembly 30. The connecting frame 12 and the connector 36 can be connected by a screw and a nut. For example, a screw hole can be provided on the connecting frame 12, with a screw threaded into the hole. The end of the connector 36 away from the first body 31 can fit against the connecting frame 12, and the screw can pass through the connector 36. The end of the screw passes through the connector 36 and is threaded to a nut. Tightening the nut can fix the connection between the connecting frame 12 and the connector 36.

[0076] It should be noted that the connector 36 can be welded to the end of the first main body 31 away from the insertion part 35. Specifically, the connector 36 can be welded to the end face of the first intermediate plate 312 and the two first side plates 311 facing away from the anti-collision beam 20.

[0077] For example, the end of the connector 36 may also extend to adhere to the end face of the second side plate 321 facing away from the anti-collision beam 20, and this end of the connector 36 may be welded to the end face of the second side plate 321 facing away from the anti-collision beam 20.

[0078] In this embodiment, the second intermediate plate 322 has an outer edge 323 protruding from the end away from the insertion part 35. The frame 11 of the connecting frame 10 is also provided with a through hole 111. When the connector 36 is connected to the connecting frame 12, the outer edge 323 can be inserted into the through hole 111 of the frame 11. At this time, the outer edge 323 can be fixedly connected to the inside of the frame 11 by welding, or the outer edge 323 can be detachably connected to the inside of the frame 11 by screws. By setting the outer edge 323 and the frame 11 for connection, the connection stability between the frame 11 and the energy absorption component 30 can be increased.

[0079] In some embodiments, the anti-collision beam 20 includes a first beam 21 and a second beam 22, the first beam 21 and the second beam 22 are connected, and the through hole 24 passes through the first beam 21 and the second beam 22 and has openings formed on the first beam 21 and the second beam 22 respectively.

[0080] The first beam 21 and the second beam 22 are hollowed out, forming an inner cavity 23 inside the anti-collision beam 20. This cavity 23 not only saves material and reduces the weight of the anti-collision beam 20, but also provides a buffer space to ensure a cushioning effect. The anti-collision beam 20 formed by the combination of the first beam 21 and the second beam 22 can be a straight structure or an arc-shaped structure. In this embodiment, to increase the anti-collision strength of the anti-collision beam 20, the entire anti-collision beam 20 is set as an arc-shaped structure.

[0081] As an example, the first beam 21 and the second beam 22 can be made of steel plates with a thickness of 2-3mm, a length of 1000-5000mm, and a width of 80mm.

[0082] The second aspect of this application provides a vehicle, which includes a vehicle body and the aforementioned anti-collision structure. The connecting frame 10 of the anti-collision structure is connected to the rear of the vehicle body, or the rear structure of the vehicle body is directly used as the connecting frame 10 of the anti-collision structure.
