Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically providing a collision avoidance structure for small offset collisions and a vehicle including the collision avoidance structure. Background Technology

[0002] With the rapid development of the automotive industry, eliminating the engine compartment allows for the placement of a front trunk, increasing overall vehicle storage space. However, as consumers' demands for personalization and entertainment increase, the need for ample front trunk space is also growing. The front compartment is also a critical area in vehicle collisions. Among numerous collisions, small overlap frontal collisions (SAW) (where the vehicle and an obstacle overlap by only 25%) are a major threat to occupant safety due to their small contact area, concentrated energy, and susceptibility to localized crumpling of the vehicle's structure. This necessitates meeting increasingly stringent safety requirements while simultaneously providing a large front trunk, further highlighting its technological challenges and engineering importance.

[0003] In conventional designs, in order to meet the safety requirements of the whole vehicle, the front trunk is small in size and can only hold small items, which cannot compare with the trunk space, let alone meet the sitting and entertainment functions of the front trunk when the vehicle is parked.

[0004] Accordingly, a new technical solution is needed in this field to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the anti-collision beam structure of existing vehicles has a small energy absorption capacity when a small offset collision occurs, which easily threatens the safety of the occupants, and to solve the problem that the user's demand for a large front trunk cannot be met in order to meet safety requirements.

[0006] In a first aspect, this utility model provides a collision avoidance structure for small offset collisions. The collision avoidance structure includes a front bumper beam, two offset collision energy-absorbing structures, two front longitudinal beams, and two energy-absorbing boxes. The front bumper beam includes a central crossbeam and two side beams. The central crossbeam extends along the Y-direction, and the two side beams are respectively installed at both ends of the central crossbeam, with the end of the side beam away from the central crossbeam inclined towards the vehicle body. The two energy-absorbing boxes are respectively installed at the ends of the two side beams near the central crossbeam. The offset collision energy absorption structures are respectively installed at the ends of the two side beams away from the middle cross beam. The two front longitudinal beams are respectively connected to the energy absorption box and the side beams that are close to them. The two side beams, the two offset collision energy absorption structures, the two front longitudinal beams and the two energy absorption boxes are all mirror images of the center line of the middle cross beam. The offset collision energy absorption structure is configured to move towards the vehicle body with the side beams in the event of a small offset collision, and thus be able to abut against the front longitudinal beams that are close to it to form a Y-axis component force.

[0007] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the offset collision energy-absorbing structure includes a support member and an energy-absorbing member. The support member is installed inside the side beam and is configured to support the side beam in the event of a small offset collision so that it does not deform in the thickness direction. The energy-absorbing member is connected to the side beam and the support member.

The two ends of the energy-absorbing plate are respectively connected to the middle area of ​​the connecting plate and form a triangular or near-triangular structure with the connecting plate, so that the energy-absorbing plate can abut against the front longitudinal beam in the event of a small offset collision.

[0009] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the width of the energy-absorbing plate is not less than 80% of the width of the side wall of the side inclined beam near the energy-absorbing plate; and / or, the connecting plate includes a first connecting segment, an intermediate transition segment and a second connecting segment connected in sequence, the connection between the first connecting segment and the intermediate transition segment is connected to the first end of the energy-absorbing plate, and the connection between the second connecting segment and the intermediate transition segment is connected to the second end of the energy-absorbing plate.

[0010] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the side beam is provided with a receiving cavity, and the supporting member includes a first H-shaped support, a second H-shaped support, and a U-shaped support connected in sequence. The first H-shaped support and the second H-shaped support are located inside the receiving cavity, and the U-shaped support is located outside the receiving cavity. The first H-shaped support is connected to the side beam and the first connecting segment through a first connector, the second H-shaped support is connected to the side beam through a second connector, and the U-shaped support is connected to the second connecting segment through a third connector.

[0011] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the first connecting member includes a first rivet nut and a first mounting bolt. When installed, the first rivet nut is mounted on the side wall of the first H-shaped support member near the connecting plate, and the first mounting bolt passes through the side wall of the first connecting section and the side inclined beam and is threadedly connected to the first rivet nut; and / or, the second connecting member is a blind rivet; and / or, the third connecting member includes a second rivet nut and a second mounting bolt. When installed, the second rivet nut is mounted on the side wall of the U-shaped support member near the connecting plate, and the second mounting bolt passes through the second connecting section and is threadedly connected to the second rivet nut; and / or, the number of first connecting members is two, and when installed, the two first connecting members are spaced apart along the width direction of the connecting plate; and / or, the number of second connecting members is two, and when installed, the two second connecting members are spaced apart along the length direction of the connecting plate.

[0012] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the number of the third connectors is one; and / or, the intermediate transition section is provided with an avoidance structure on the side near the side inclined beam.

[0013] In the preferred embodiment of the above-described anti-collision structure for small offset collisions, in the direction perpendicular to the connecting plate, the outer side of the first H-shaped support member near the connecting plate is lower than the outer side of the second H-shaped support member near the connecting plate; and / or, in the direction perpendicular to the connecting plate, the outer side of the second H-shaped support member near the connecting plate is lower than the outer side of the U-shaped support member near the connecting plate.

[0014] In the preferred embodiment of the above-mentioned anti-collision structure for small offset collisions, the angle between the extension line of the side beam and the middle crossbeam is 5° to 35°.

[0015] In a second aspect, the present invention provides a vehicle comprising the aforementioned anti-collision structure for small offset collisions.

[0016] With the above technical solution adopted, the anti-collision structure of this utility model includes a front anti-collision beam, two offset collision energy-absorbing structures, two front longitudinal beams, and two energy-absorbing boxes. The two side beams, two offset collision energy-absorbing structures, two front longitudinal beams, and two energy-absorbing boxes are all mirror-image positioned relative to the centerline of the intermediate crossbeam. The offset collision energy-absorbing structures are configured to move towards the vehicle body with the side beams in the event of a small offset collision, thereby abutting against the adjacent front longitudinal beams to form a Y-axis component force. This configuration, by setting offset collision energy-absorbing structures in the small offset collision overlap areas at both ends of the front anti-collision beam, ensures that in the event of a small offset collision... The offset collision energy absorption structure can move towards the vehicle body along with the side beam, and then abut against the adjacent front longitudinal beam to form a Y-axis component force. At the moment of collision, the front anti-collision beam and the front longitudinal beam can be subjected to force in time, thus forming a Y-axis component force in the initial stage of the collision. This can push the obstacle avoidance to reduce the force on the vehicle during the entire collision process, improve the vehicle's safety performance, and better protect the safety of the occupants. In addition, the anti-collision structure of this utility model can effectively ensure the integrity of the passenger compartment in the event of a small offset collision. Its small offset collision performance can meet the requirements of designing a large front trunk and front trunk seating and entertainment functions, thus improving the user experience.

[0017] Furthermore, the offset collision energy-absorbing structure includes a support member and an energy-absorbing member. The support member is installed inside the side beam and is used to support the side beam in the event of a small offset collision to prevent it from deforming in the thickness direction. The energy-absorbing member is connected to the side beam and the support member and is located on the outside of the side beam and is positioned towards the expected approaching front longitudinal beam. With this configuration, in the event of a small offset collision, the offset collision energy-absorbing structure moves towards the vehicle body along with the side beam, so that the energy-absorbing member abuts against the front longitudinal beam that is close to it. At this time, the impact force is relatively large, and the support member can support the side beam to maintain a stable shape, avoiding being crushed and deformed due to the impact force and rebound force, thereby keeping the shape of the side beam stable in the thickness direction. In addition, the energy-absorbing member abuts against the front longitudinal beam, absorbs energy and generates a reaction force, which can push the obstacle avoidance out, effectively improving safety. Moreover, the overall structure is simple and convenient to manufacture, assemble and use.

[0018] Furthermore, the energy-absorbing component includes a connecting plate and an energy-absorbing plate. The connecting plate is used to install and connect the energy-absorbing component with the supporting component and the side beam. The energy-absorbing plate is used to abut against the front longitudinal beam when a small offset collision occurs, thereby absorbing energy and transmitting force. At the same time, the connecting plate and the energy-absorbing plate form a triangular or near-triangular structure, which can improve the stability when abutting, prevent the contact point between the energy-absorbing plate and the front longitudinal beam from shifting at the moment of abutting, improve the stress stability, and its structure is simple, convenient for production, manufacturing and assembly.

[0019] Furthermore, the width of the energy-absorbing plate is not less than 80% of the width of the side wall of the inclined beam closest to the energy-absorbing plate, so that the energy-absorbing plate has sufficient width, thereby ensuring a sufficiently large contact area between the energy-absorbing plate and the front longitudinal beam when they abut, thus improving the stability of the abutment.

[0020] Furthermore, the inclined beam is provided with a receiving cavity, and the supporting components include a first H-shaped support, a second H-shaped support, and a square support connected in sequence. The first and second H-shaped supports are located inside the receiving cavity. The first H-shaped support is connected to the inclined beam and the first connecting section through a first connector, and the second H-shaped support is connected to the inclined beam through a second connector. The square support is located outside the receiving cavity and is connected to the second connecting section through a third connector. This arrangement results in a simple structure, high support strength, and convenient assembly and use of the supporting components.

[0021] Furthermore, the first connecting component is set as the first rivet nut and the first mounting bolt, which facilitates installation and use and ensures high connection stability.

[0022] Furthermore, the second connector is designed as a blind rivet, which facilitates assembly and ensures high connection stability.

[0023] Furthermore, the third connector is set as the second rivet nut and the second mounting bolt, which facilitates installation and use and ensures high connection stability.

[0024] Furthermore, the number of first connectors is two, and the two first connectors are distributed at intervals along the width direction of the connecting plate. This can restrict the rotation between the supporting member, the inclined beam and the energy-absorbing member, and fix the supporting member, the inclined beam and the energy-absorbing member at two different positions. At the same time, in conjunction with the second connector and the third connector, it can better improve the connection stability between the supporting member and the inclined beam and the energy-absorbing member.

[0025] Furthermore, the number of second connectors is increased to two, with the two second connectors spaced apart along the length of the connecting plate. This restricts rotation between the support member and the inclined beam, thereby improving the connection stability between the support member and the inclined beam.

[0026] Furthermore, by making the number of third connectors to one, which works in conjunction with the first connector, the connection stability between the supporting member and the energy-absorbing member can be improved.

[0027] Furthermore, the intermediate transition section has a clearance structure on the side near the inclined beam. This clearance structure can form a receiving space to accommodate the nail head after the pop rivet is installed, so that when the connecting plate is installed, its first connecting section and second connecting section are tightly fitted and fixed to the inclined beam, thereby improving the connection stability between the energy-absorbing component and the inclined beam.

[0028] Furthermore, in the direction perpendicular to the connecting plate, the outer side of the first H-shaped support near the connecting plate is lower than the outer side of the second H-shaped support near the connecting plate, thereby forming a step between the first H-shaped support and the second H-shaped support on the side of the support member closest to the connecting plate. This allows the second H-shaped support to be tightly fitted and fixed to the inner wall of the inclined beam when the support member is installed, thereby improving the connection stability between the support member and the inclined beam.

[0029] Furthermore, in the direction perpendicular to the connecting plate, the outer side of the second H-shaped support near the connecting plate is lower than the outer side of the U-shaped support near the connecting plate, thus forming a step between the second H-shaped support and the U-shaped support on the side of the support member near the connecting plate. During installation, the side of the U-shaped support near the connecting plate can be used as a positioning surface, enabling quick installation and convenient use.

[0030] Furthermore, the angle between the extension lines of the side beam and the middle crossbeam is 5° to 35°, which is suitable for small offset collision conditions at different angles, making it easy to use and providing good buffering and energy absorption performance.

[0046] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0047] It should be noted that in the description of this utility model, terms such as "inner" and "outer" indicating directional or positional relationships are based on the directional or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0048] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through other components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] Based on the issues pointed out in the background art, existing vehicles have limited energy absorption capacity of the anti-collision beam structure in the event of a small offset collision, which may threaten the safety of occupants, and the inability to meet users' demand for a large front cargo compartment in order to meet safety requirements.

[0050] This invention provides a collision avoidance structure for small offset collisions. By setting offset collision energy-absorbing structures in the small offset collision overlap area at both ends of the front bumper beam, the offset collision energy-absorbing structures can move towards the vehicle body along with the side beam during a small offset collision, and then abut against the adjacent front longitudinal beam to form a Y-axis component force. At the moment of collision, the front bumper beam and the front longitudinal beam can be subjected to force in time, thus forming a Y-axis component force in the initial stage of the collision. This can push the obstacle avoidance out to reduce the force on the vehicle during the entire collision process, improve the vehicle's safety performance, and better protect the safety of the occupants. In addition, the collision avoidance structure of this invention can effectively ensure the integrity of the passenger compartment when the vehicle is involved in a small offset collision. Its small offset collision performance can meet the requirements of designing a large front trunk and front trunk seating and entertainment functions, improving the user experience.

[0051] Specifically, please also refer to Figures 1 to 6 The anti-collision structure for small offset collisions of this utility model includes a front anti-collision beam 1, two offset collision energy-absorbing structures 2, two front longitudinal beams 3 and two energy-absorbing boxes 4, wherein the two side beams 12, the two offset collision energy-absorbing structures 2, the two front longitudinal beams 3 and the two energy-absorbing boxes 4 are all mirror images of the center line of the middle crossbeam 11.

[0052] Specifically, the front bumper beam 1 includes a central crossbeam 11 and two side beams 12. The central crossbeam 11 extends along the Y direction, and the two side beams 12 are respectively installed at both ends of the central crossbeam 11, with the end of the side beam 12 away from the central crossbeam 11 inclined towards the vehicle body. This inclined arrangement of the side beams 12 relative to the central crossbeam 11 towards the vehicle body allows them to move towards the front longitudinal beam 3 after being subjected to force during a small offset collision. This enables the offset collision energy absorption structure 2 to smoothly abut against the front longitudinal beam 3, thereby dispersing the force between the front longitudinal beam 3 and the front bumper beam 1.

[0053] Two energy-absorbing boxes 4 are respectively installed at one end of the two side beams 12 near the middle cross beam 11, and two offset collision energy-absorbing structures 2 are respectively installed at one end of the two side beams 12 away from the middle cross beam 11. The offset collision energy-absorbing structure 2 is configured to move towards the vehicle body with the side beams 12 in the event of a small offset collision, and thus be able to abut against the front longitudinal beam 3 that is close to it to form a Y-direction component force.

[0054] The anti-collision structure of this utility model includes a front anti-collision beam 1, two offset collision energy-absorbing structures 2, two front longitudinal beams 3, and two energy-absorbing boxes 4. The two side beams 12, the two offset collision energy-absorbing structures 2, the two front longitudinal beams 3, and the two energy-absorbing boxes 4 are all mirror images of the centerline of the intermediate crossbeam 11. The offset collision energy-absorbing structures 2 are configured to move towards the vehicle body along with the side beams 12 in the event of a small offset collision, thereby abutting against the front longitudinal beams 3 that are close to them to form a Y-axis component force. This arrangement, through the front anti-collision beam 1, provides a strong anti-collision structure. Offset collision energy absorption structures 2 are set in the small offset collision overlap area at both ends of the impact beam 1. When a small offset collision occurs, the offset collision energy absorption structure 2 can move towards the vehicle body along with the side beam 12, and then abut against the front longitudinal beam 3 that is close to it, forming a Y-direction component force. At the moment of collision, the front anti-collision beam 1 and the front longitudinal beam 3 can be subjected to force in time, so that a Y-direction component force can be formed in the initial stage of the collision. This can push the obstacle out to reduce the force on the vehicle during the entire collision process, improve the vehicle body safety performance, and better protect the safety of the occupants.

[0055] Furthermore, the anti-collision structure of this utility model can effectively ensure the integrity of the passenger compartment when the vehicle is involved in a small offset collision. Its small offset collision performance can meet the requirements of designing a large front trunk and front trunk seating and entertainment functions, thereby improving the user experience.

[0056] Preferably, the middle crossbeam 11 and the side inclined beam 12 are an integral structure, which is convenient for production, has high connection strength, and is more convenient to use.

[0057] It should be noted that this utility model does not impose any restrictions on the specific structure of the offset collision energy absorption structure 2. In practical applications, those skilled in the art can set the specific structure of the offset collision energy absorption structure 2 according to the needs of the driver. Adjustments and changes to the structure of the offset collision energy absorption structure 2 do not deviate from the basic principles of this utility model and should be limited to the protection scope of this utility model.

[0058] Preferably, please participate simultaneously. Figures 1 to 6 The offset collision energy absorption structure 2 includes a support member 21 and an energy absorption member 22. The support member 21 is installed inside the side beam 12. The support member 21 is configured to support the side beam 12 in the event of a small offset collision so that it does not deform in the thickness direction. The energy absorption member 22 is connected to the side beam 12 and the support member 21. The energy absorption member 22 is located outside the side beam 12 and is positioned towards the front longitudinal beam 3 that is close to it so that it can abut against the front longitudinal beam 3 that is close to it in the event of a small offset collision.

[0059] In this configuration, during a small offset collision, the offset collision energy-absorbing structure 2 moves toward the vehicle body along with the side beam 12, so that the energy-absorbing component 22 abuts against the adjacent front longitudinal beam 3. At this time, the impact force is relatively large, and the support component 21 can support the side beam 12 to maintain a stable shape, avoiding being flattened and deformed due to the impact force and rebound force, thereby keeping the shape of the side beam 12 stable in the thickness direction. In addition, the energy-absorbing component 22 abuts against the front longitudinal beam 3, absorbs energy and forms a reaction force, which can push the obstacle avoidance out, effectively improving safety. Moreover, the overall structure is simple and convenient to manufacture, assemble and use.

[0060] Preferably, please also refer to Figure 4 and Figure 6 The energy-absorbing component 22 includes a connecting plate 221 and an energy-absorbing plate 222 connected together. The two ends of the energy-absorbing plate 222 are respectively connected to the middle area of ​​the connecting plate 221 and form a triangular or triangular structure with the connecting plate 221 so that the energy-absorbing plate 222 can abut against the front longitudinal beam 3 in the event of a small offset collision.

[0061] The energy-absorbing component 22 includes a connecting plate 221 and an energy-absorbing plate 222 connected together. The connecting plate 221 is used to install and connect the energy-absorbing component 22 with the supporting component 21 and the side inclined beam 12. The energy-absorbing plate 222 is used to abut against the front longitudinal beam 3 when a small offset collision occurs, thereby absorbing energy and transmitting force. At the same time, the connecting plate 221 and the energy-absorbing plate 222 form a triangular or near-triangular structure, which can improve the stability when abutting, and can prevent the contact point between the energy-absorbing plate 222 and the front longitudinal beam 3 from shifting at the moment of abutting, thus improving the stress stability. Moreover, its structure is simple and convenient for production, manufacturing and assembly.

[0062] It should be noted that this utility model does not impose any restrictions on the specific connection method between the connecting plate 221 and the energy-absorbing plate 222. In practical applications, those skilled in the art can set the connection method of the connecting plate 221 and the energy-absorbing plate 222 according to actual needs. For example, the energy-absorbing plate 222 can be welded and fixed to the connecting plate 221, or the energy-absorbing plate 222 and the connecting plate 221 can be set as an integral structure. Adjustments and changes to the connection method between the energy-absorbing plate 222 and the connecting plate 221 do not deviate from the basic principle of this utility model and should be limited to the protection scope of this utility model.

[0063] In a preferred embodiment, the energy-absorbing plate 222 and the connecting plate 221 are integrally formed. Making the energy-absorbing plate 222 and the connecting plate 221 an integral structure facilitates manufacturing and reduces costs.

[0064] Preferably, the width of the energy-absorbing plate 222 is not less than 80% of the width of the side wall of the inclined beam 12 near the energy-absorbing plate 222.

[0065] The width of the energy-absorbing plate 222 is not less than 80% of the width of the side wall of the inclined beam 12 near the energy-absorbing plate 222, so that the energy-absorbing plate 222 has sufficient width, so that the energy-absorbing plate 222 and the front longitudinal beam 3 make surface contact contact when they abut, rather than point contact contact, which can maintain a sufficiently large contact area, prevent the energy-absorbing plate 222 from sliding when abutting, and improve the stability of the abutment.

[0066] Preferably, please continue reading. Figure 4 and Figure 6 The connecting plate 221 includes a first connecting segment 2211, an intermediate transition segment 2212, and a second connecting segment 2213 connected in sequence. The connection between the first connecting segment 2211 and the intermediate transition segment 2212 is connected to the first end of the energy-absorbing plate 222, and the connection between the second connecting segment 2213 and the intermediate transition segment 2212 is connected to the second end of the energy-absorbing plate 222.

[0067] The connecting plate 221 includes a first connecting section 2211, a second connecting section 2213 and an intermediate transition section 2212 connected in sequence. The first connecting section 2211 is used to connect with the side beam 12 and the support member 21, the second connecting section 2213 is used to connect with the support member 21, and the intermediate transition section 2212 is used to connect with the energy-absorbing plate 222 to form a triangular or triangular structure.

[0068] Preferably, please also refer to Figure 5 and Figure 6 The inclined beam 12 has a receiving cavity 121. The supporting member 21 includes a first H-shaped support member 211, a second H-shaped support member 212, and a square support member 213 connected in sequence. The first H-shaped support member 211 and the second H-shaped support member 212 are located inside the receiving cavity 121, and the square support member 213 is located outside the receiving cavity 121. The first H-shaped support member 211 is connected to the inclined beam 12 and the first connecting section 2211 through the first connector 5. The second H-shaped support member 212 is connected to the inclined beam 12 through the second connector 6. The square support member 213 is connected to the second connecting section 2213 through the third connector 7.

[0069] This configuration results in a simple structure for the support component 21, high support strength, and easy assembly and use.

[0070] It should be noted that this utility model does not impose any restrictions on the specific connection methods of the first sun-shaped support 211, the second sun-shaped support 212, and the square-shaped support 213. In practical applications, those skilled in the art can set the connection methods of the first sun-shaped support 211, the second sun-shaped support 212, and the square-shaped support 213 according to actual needs. For example, the first sun-shaped support 211, the second sun-shaped support 212, and the square-shaped support 213 can be welded and fixed, or the first sun-shaped support 211, the second sun-shaped support 212, and the square-shaped support 213 can be set as an integral structure. Adjustments and changes to the connection methods of the first sun-shaped support 211, the second sun-shaped support 212, and the square-shaped support 213 do not deviate from the basic principles of this utility model and should be limited to the protection scope of this utility model.

[0071] Preferably, the first H-shaped support 211, the second H-shaped support 212, and the square support 213 are integrally formed. Making the first H-shaped support 211, the second H-shaped support 212, and the square support 213 into an integral structure facilitates manufacturing and reduces costs.

[0072] It should be noted that although the support structure 21 is configured in the above preferred embodiment as a first H-shaped support member 211, a second H-shaped support member 212, and a square support member 213 connected in sequence, this should not limit the scope of protection of this utility model. In practical applications, those skilled in the art can also configure the support structure 21 as other structures, for example, configuring the support structure as three square support members connected in sequence, or configuring the support structure as a first o-shaped support member, a second o-shaped support member, and a square support member connected in sequence, etc. Adjustments and changes to the support mechanism 21 do not deviate from the basic principles of this utility model and should all be limited to the scope of protection of this utility model.

When installed, the first rivet nut 51 is mounted on the side wall of the first H-shaped support member 211 near the connecting plate 221. The first mounting bolt 52 passes through the side wall of the first connecting section 2211 and the side inclined beam 12 and is threadedly connected to the first rivet nut 51. Specifically, the first H-shaped support member 211 has a first mounting hole for mounting the first rivet nut 51, the first connecting section 2211 has a first through hole, and the side inclined beam 12 has a first mating hole. The first through hole and the first mating hole are used to pass through the first mounting bolt 52, so that the first mounting bolt 52 passes through and connects with the first rivet nut 51, thereby locking and fixing the first connecting section 2211, the side inclined beam 12, and the first H-shaped support member 211.

[0074] The first connector 5 is configured as the first rivet nut 51 and the first mounting bolt 52, which facilitates installation and use and ensures high connection stability.

[0075] Preferably, the second connector 6 is a blind rivet. Specifically, the second H-shaped support 212 is provided with a second mounting hole, and the side beam 12 is provided with a second mating hole. The second mounting hole and the second mating hole are arranged opposite each other so that the rivet screw can pass through and lock the second H-shaped support 212 and the side beam 12 in place.

[0076] The second connector 6 is designed as a blind rivet, which facilitates assembly and ensures high connection stability.

[0077] Preferably, please also refer to Figure 2 , Figure 6 , Figure 5 and Figure 6 The third connecting member 7 includes a second rivet nut 71 and a second mounting bolt 72. When installed, the second rivet nut 71 is mounted on the side wall of the U-shaped support 213 near the connecting plate 221. The second mounting bolt 72 passes through the second connecting section 2213 and is threadedly connected to the second rivet nut 71. Specifically, the U-shaped support 213 has a third mounting hole for mounting the second rivet nut 71, and the second connecting section 2213 has a second through hole for passing through the second mounting bolt 72, allowing the second mounting bolt 72 to pass through and connect with the second rivet nut 71, thereby locking and fixing the second connecting section 2213 and the U-shaped support 213.

[0078] The third connector 7 is set as the second rivet nut 71 and the second mounting bolt 72, which facilitates installation and use and ensures high connection stability.

[0079] It should be noted that this utility model does not impose any restrictions on the number of the first connector 5, the second connector 6, and the third connector 7. In practical applications, those skilled in the art can set the number of the first connector 5, the second connector 6, and the third connector 7 according to actual needs.

[0080] In a preferred embodiment, there are two first connectors 5, which are spaced apart along the width direction of the connecting plate 221 when installed.

[0081] The number of first connectors 5 is two, and the two first connectors 5 are distributed at intervals along the width direction of the connecting plate 221. This can restrict the rotation of the support member 21, the side beam 12 and the energy-absorbing member 22 relative to each other, and fix the support member 21, the side beam 12 and the energy-absorbing member 22 at two different positions. At the same time, it can be used in conjunction with the second connector 6 and the third connector 7 to better improve the connection stability of the support member 21 with the side beam 12 and the energy-absorbing member 22.

[0082] In a preferred embodiment, there are two second connectors 6, which are spaced apart along the length of the connecting plate 221 when installed.

[0083] The number of second connectors 6 is two, and the two second connectors 6 are distributed at intervals along the length direction of the connecting plate 221. This can restrict the rotation between the support member 21 and the side inclined beam 12, and can better improve the connection stability between the support member 21 and the side inclined beam 12.

[0084] In a preferred embodiment, the number of third connectors 7 is one. Having only one third connector 7, used in conjunction with the first connector 5, can improve the connection stability between the support member 21 and the energy-absorbing member 22.

[0085] Preferably, please also refer to Figure 4 and Figure 6 The intermediate transition section 2212 has a clearance structure 2214 on the side near the inclined beam 12.

[0086] The intermediate transition section 2212 is provided with a clearance structure 2214 on the side near the side inclined beam 12. The clearance structure 2214 can form a receiving space to accommodate the nail head after the pop rivet is installed, so that when the connecting plate 221 is installed, its first connecting section 2211 and second connecting section 2213 are tightly fitted and fixed to the side inclined beam 12, thereby improving the connection stability between the energy-absorbing member 22 and the side inclined beam 12.

[0087] Preferably, please also refer to Figure 5 and Figure 6In the direction perpendicular to the connecting plate 221, the outer side of the first H-shaped support 211 near the connecting plate 221 is lower than the outer side of the second H-shaped support 212 near the connecting plate 221.

[0088] In the direction perpendicular to the connecting plate 221, the outer side of the first H-shaped support 211 near the connecting plate 221 is lower than the outer side of the second H-shaped support 212 near the connecting plate 221, thereby forming a step between the first H-shaped support 211 and the second H-shaped support 212 on the side of the support member 21 near the connecting plate 221. This allows the second H-shaped support 212 to be tightly fitted and fixed to the inner wall of the side inclined beam 12 when the support member 21 is installed, thereby improving the connection stability between the support member 21 and the side inclined beam 12.

[0089] Preferably, please also refer to Figure 5 and Figure 6 In the direction perpendicular to the connecting plate 221, the outer side of the second H-shaped support 212 near the connecting plate 221 is lower than the outer side of the square support 213 near the connecting plate 221.

[0090] In the direction perpendicular to the connecting plate 221, the outer side of the second H-shaped support 212 near the connecting plate 221 is lower than the outer side of the U-shaped support 213 near the connecting plate 221, so that a step is formed between the second H-shaped support 212 and the U-shaped support 213 on the side of the support member 21 near the connecting plate 221. During installation, the side of the U-shaped support 213 near the connecting plate 221 can be used as a positioning surface, which can be quickly installed in place and facilitates quick installation and use.

[0091] Preferably, the angle between the extension lines of the side beam 12 and the middle crossbeam 11 is 5° to 35°. This angle of 5° to 35° makes it suitable for small-offset collisions at different angles, facilitating use and providing good buffering and energy absorption performance.

[0092] In a second aspect, the present invention provides a vehicle that includes the anti-collision structure for small offset collisions provided in the first aspect.

[0093] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
