For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0037] The following is for reference. Figures 1-8 The elephant trunk bridge assembly 100 according to an embodiment of the present invention can increase the transmission path of collision force, improve the reliability of transmitting and dissipating collision force, effectively reduce the transmission of collision force into the passenger compartment, and thus effectively improve the collision performance and safety of the vehicle.

[0038] like Figures 1-8 As shown, an elephant trunk bridge assembly 100 according to an embodiment of the present invention includes: a transition structure 1 and an elephant trunk bridge body 2.

[0039] The adapter structure 1 is adapted to be connected to the energy-absorbing box 201 and is used to connect to the front part of the front longitudinal beam 203; the front part of the elephant trunk body 2 is connected to the adapter structure 1, the rear part of the elephant trunk body 2 is used to connect to the A-pillar, and at least part of the elephant trunk body 2 is constructed as a collapsible section 21, which is constructed to be inclined outward from bottom to top in the front-back direction.

[0040] Specifically, the energy-absorbing box 201 is connected to the rear side of the anti-collision beam 202. It is used to absorb the collision force through deformation (such as wrinkling, crushing, etc.) when a collision occurs at the front of the vehicle. It can also transfer the collision force acting on the anti-collision beam 202 to the rear side of the vehicle for dissipation, thereby reducing the transmission of the collision force into the passenger compartment and improving the vehicle's collision performance and safety. The adapter structure 1 is connected to the front of the front longitudinal beam 203 and is connected to the energy-absorbing box 201. The adapter structure 1 can be connected between the energy-absorbing box 201 and the front longitudinal beam 203, so that the collision force acting on the anti-collision beam 202 can be transmitted to the front longitudinal beam 203 through the energy-absorbing box 201 to transmit and dissipate the collision force.

[0041] Among them, such as Figure 1 As shown, the rear part of the front longitudinal beam 203 is connected to the front structure 204, which connects the front longitudinal beam 203 between the transition structure 1 and the front structure 204. This allows the collision force acting on the anti-collision beam 202 to be further transmitted to the front structure 204 through the front longitudinal beam 203, so as to further transmit and dissipate the collision force.

[0042] Meanwhile, the elephant trunk body 2 can also be used to transmit and dissipate the collision force of the vehicle. By connecting the front part of the elephant trunk body 2 to the adapter structure 1, the adapter structure 1 can be connected between the energy absorption box 201 and the elephant trunk body 2, so that the collision force acting on the anti-collision beam 202 can be transmitted to the elephant trunk body 2 through the energy absorption box 201 to transmit and dissipate the collision force. Furthermore, by connecting the rear part of the elephant trunk body 2 to the A-pillar, the elephant trunk body 2 can be connected between the adapter structure 1 and the A-pillar, so that the collision force acting on the anti-collision beam 202 can be further transmitted to the A-pillar through the elephant trunk body 2 to further transmit and dissipate the collision force.

[0043] Thus, when a collision occurs at the front of the vehicle, such as a head-on collision or an offset collision, the collision force acting on the anti-collision beam 202 can be transmitted to the front longitudinal beam 203 and the elephant trunk beam body 2 through the energy absorption box 201, and then to the front structure 204 and the A-pillar through the front longitudinal beam 203 and the elephant trunk beam body 2, respectively. This increases the transmission path of the collision force, improves the reliability of the transmission and dissipation of the collision force, effectively reduces the transmission of the collision force into the passenger compartment, and thus effectively improves the vehicle's collision performance and safety.

[0044] The elephant trunk body 2 can be constructed to extend in the front-to-back direction so that the front and rear parts of the elephant trunk body 2 can approach the adapter structure 1 and the A-pillar respectively, so as to connect the front and rear parts of the elephant trunk body 2 to the adapter structure 1 and the A-pillar respectively, thereby improving the reliability of the elephant trunk body 2.

[0045] Furthermore, by constructing at least a portion of the elephant trunk body 2 as a collapsible segment 21, the elephant trunk body 2 can be partially or entirely constructed as a collapsible segment 21. The collapsible segment 21 is used to absorb the impact force through deformation. That is, the elephant trunk body 2 can absorb part of the impact force through the collapsible segment 21 to further reduce the transmission of the impact force into the passenger compartment. Moreover, by constructing the collapsible segment 21 to be inclined outward from bottom to top along the front-rear direction, the elephant trunk body 2 can simultaneously bend and deform upward and backward to absorb the impact force when subjected to the impact force, thereby improving the reliability of the elephant trunk body 2 in absorbing the impact force.

[0046] In such Figures 1-6 and Figure 8 In the embodiment shown, part of the structure of the elephant trunk body 2 is a collapsible segment 21, which can help improve the structural strength of the elephant trunk body 2, thereby improving the reliability of the elephant trunk body 2 in absorbing and transmitting the impact force.

[0047] Among them, such as Figure 1 and Figure 7 As shown, the front end of the front longitudinal beam 203 is connected to the energy-absorbing box 201 through the adapter structure 1, and the rear end of the front longitudinal beam 203 is connected to the front structure 204. In this way, the structural strength of the front and rear ends of the front longitudinal beam 203 is greater than that of the middle part. As a result, when the collision force is transmitted to the front longitudinal beam 203, the middle part of the front longitudinal beam 203 can be bent inward to absorb energy. Thus, when the front of the vehicle collides, during the transmission of the collision force from front to back, the front longitudinal beam 203 can be bent inward, and the elephant trunk beam body 2 can be bent upward and backward at the same time, which can improve the stability of the overall structure while rapidly transmitting the collision force.

[0048] And, such as Figure 1As shown, a connecting structure 205 connects the elephant trunk beam body 2 and the A-pillar. The connecting structure 205 is used to connect the elephant trunk beam body 2 and the A-pillar to transfer the collision force on the elephant trunk beam body 2 to the A-pillar, thereby improving the reliability of the transmission and dissipation of the collision force. The connecting structure 205 is also connected to the front longitudinal beam 203 through the wheel arch inner plate 206, which can improve the reliability of the working of the connecting structure 205. In actual design, the sub-anti-collision beam can also be connected to the suspension. When the front of the vehicle is hit by a collision, the force acting on the sub-anti-collision beam 202 can be transmitted to the suspension. In this way, the collision force can be transmitted through the elephant trunk beam body 2, the front longitudinal beam 203 and the suspension along the upper, middle and lower paths, respectively, effectively transmitting and dissipating the collision force, and greatly improving the collision performance and safety of the vehicle.

[0049] It should be noted that there are two elephant trunk bridge components 100 in this application. The two elephant trunk bridge components 100 are distributed laterally along the vehicle and are respectively connected to two energy absorption boxes 201. The following description will take the one elephant trunk bridge component 100 located on the left as an example.

[0050] According to the embodiment of the present invention, the elephant trunk beam assembly 100 can connect the energy-absorbing box 201 to the front longitudinal beam 203 and the elephant trunk beam body 2 simultaneously by setting the transition structure 1. When a collision occurs at the front of the vehicle, the collision force acting on the anti-collision beam 202 can be transmitted through the energy-absorbing box 201 to the front longitudinal beam 203 and the elephant trunk beam body 2 respectively. Furthermore, the collision force can be transmitted through the front longitudinal beam 203 and the elephant trunk beam body 2 to the front structure 204 and the A-pillar respectively. This increases the transmission path of the collision force, improves the reliability of the transmission and dissipation of the collision force, and effectively reduces the transmission of the collision force into the passenger compartment. This effectively improves the collision performance and safety of the vehicle. In addition, at least a portion of the elephant trunk beam body 2 is constructed as a crumple section 21, and the crumple section 21 is constructed to be inclined outward from bottom to top in the front-rear direction. This allows the crumple section 21 to bend and deform upward and backward simultaneously to absorb the collision force, further reducing the transmission of the collision force into the passenger compartment.

[0051] In some embodiments, the adapter structure 1 includes a mounting motherboard 11, the front side of which is adapted to be connected to the energy-absorbing box 201, the front part of the elephant trunk body 2 is connected to the rear side of the mounting motherboard 11, and the front part of the front longitudinal beam 203 is adapted to be connected to the rear side of the mounting motherboard 11.

[0052] Specifically, the adapter structure 1 is used to connect the energy-absorbing box 201 to the front longitudinal beam 203 and the elephant trunk beam body 2 respectively. The adapter structure 1 includes a mounting main board 11. The front side of the mounting main board 11 is connected to the energy-absorbing box 201, so that the adapter structure 1 and the energy-absorbing box 201 can be connected through the mounting main board 11. The front part of the elephant trunk beam body 2 is connected to the rear side of the mounting main board 11, so that the adapter structure 1 and the elephant trunk beam body 2 can be connected through the mounting main board 11. In this way, the mounting main board 11 can be connected between the energy-absorbing box 201 and the elephant trunk beam body 2, so that the collision force on the energy-absorbing box 201 can be transmitted to the elephant trunk beam body 2 through the mounting main board 11. Moreover, the energy-absorbing box 201 and the elephant trunk beam body 2 are connected to the front and rear sides of the mounting main board 11 respectively, so that the energy-absorbing box 201 and the elephant trunk beam body 2 can be connected in the front-rear direction through the mounting main board 11, thereby improving the reliability of the transmission of the collision force from the energy-absorbing box 201 to the elephant trunk beam body 2 in the front-rear direction.

[0053] Meanwhile, the front part of the front longitudinal beam 203 is connected to the rear side of the mounting main board 11, so that the connection between the adapter structure 1 and the front longitudinal beam 203 can be realized through the mounting main board 11. In this way, the mounting main board 11 can be connected between the energy-absorbing box 201 and the front longitudinal beam 203, so that the collision force on the energy-absorbing box 201 can be transmitted to the front longitudinal beam 203 through the mounting main board 11. Moreover, the energy-absorbing box 201 and the front longitudinal beam 203 are respectively connected to the front and rear sides of the mounting main board 11, so that the energy-absorbing box 201 and the front longitudinal beam 203 can be connected in the front-rear direction through the mounting main board 11, thereby improving the reliability of the collision force being transmitted from the energy-absorbing box 201 to the front longitudinal beam 203 in the front-rear direction.

[0054] Among them, such as Figures 2-4 As shown in Figure 6, the mounting motherboard 11 is provided with a first connection hole 111. The first connection hole 111 is used to pass through a first connector, and the first connector can also pass through the energy-absorbing box 201. Thus, the energy-absorbing box 201 can be connected to the mounting motherboard 11 through the first connector. The first connector can be an M10 bolt, that is, the connection between the energy-absorbing box 201 and the mounting motherboard 11 is detachable, which makes it easy to connect or separate the energy-absorbing box 201 from the mounting motherboard 11. This facilitates the replacement of the energy-absorbing box 201 when it fails, reducing maintenance costs. There are five first connection holes 111, and correspondingly, there are also five first connectors. The five first connection holes 111 are distributed at intervals, so the energy-absorbing box 201 can be connected to the mounting motherboard 11 at five positions simultaneously through the five first connectors, which can improve the reliability and stability of the connection between the two.

[0055] In some embodiments, a first mounting plate 12 and a second mounting plate 13 are connected to the rear side of the mounting motherboard 11. The first mounting plate 12 and the second mounting plate 13 are distributed laterally across the vehicle, and at least a portion of the elephant trunk body 2 is connected between the first mounting plate 12 and the second mounting plate 13.

[0056] Specifically, the front of the elephant trunk bridge body 2 is connected to the rear of the mounting main board 11. The mounting main board 11 is connected to a first mounting plate 12 and a second mounting plate 13. The first mounting plate 12 and the second mounting plate 13 are spaced apart along the lateral direction of the vehicle, so that there is a certain distance between the first mounting plate 12 and the second mounting plate 13. At least part of the elephant trunk bridge body 2 is connected between the first mounting plate 12 and the second mounting plate 13, so that at least part of the elephant trunk bridge body 2 can be inserted between the first mounting plate 12 and the second mounting plate 13 and connected to the first mounting plate 12 and the second mounting plate 13, thereby realizing the connection between the elephant trunk bridge body 2 and the adapter structure 1.

[0057] Furthermore, the first mounting plate 12 and the second mounting plate 13 are both connected to the rear side of the mounting main board 11. They can be connected by welding to fix the first mounting plate 12 and the second mounting plate 13. The first mounting plate 12 is constructed in an L-shape, and both the first mounting plate 12 and the second mounting plate 13 can be brought close to the elephant trunk body 2 to facilitate the connection between the elephant trunk body 2 and the first mounting plate 12 and the second mounting plate 13.

[0058] In such Figure 2 and Figure 4 In the embodiment shown, the first mounting plate 12 is provided with a clearance hole 121, and the second mounting plate 13 is provided with a third connecting hole. The clearance hole 121 is used to avoid the third connecting member 131, so that the third connecting member 131 can be simultaneously inserted into the elephant trunk beam body 2 and the second mounting plate 13. Then, the elephant trunk beam body 2 and the second mounting plate 13 can be connected through the third connecting member 131. The third connecting member 131 can be an M10 bolt, and the first mounting plate 12 and the elephant trunk beam body 2 can be connected by welding. In this way, the elephant trunk beam body 2 can be connected to the first mounting plate 12 and the second mounting plate 13 at the same time, which can improve the connection reliability and connection stability between the elephant trunk beam body 2 and the adapter structure 1.

[0059] In some embodiments, the second mounting plate 13 is located inside the first mounting plate 12, and the second mounting plate 13 has a connecting flange 132 formed on the side opposite to the first mounting plate 12, the connecting flange 132 being used to connect to the outer side of the front longitudinal beam 203.

[0060] Specifically, the first mounting plate 12 and the second mounting plate 13 are spaced apart laterally along the vehicle. The second mounting plate 13 is located inside the first mounting plate 12, i.e., the second mounting plate 13 is located on the side of the first mounting plate 12 facing the center of the vehicle. At least a portion of the trunk beam body 2 extends between the first mounting plate 12 and the second mounting plate 13, i.e., the trunk beam body 2 is located on the side of the second mounting plate 13 facing the first mounting plate 12. The second mounting plate 13 has a connecting flange 132 on the side away from the first mounting plate 12. The connecting flange 132 is used to connect with the outer side of the front longitudinal beam 203, i.e., the front longitudinal beam 203 is located on the side of the second mounting plate 13 away from the first mounting plate 12. Thus, the trunk beam body 2 and the front longitudinal beam 203 can be separated by the second mounting plate 13 to improve the reliability of the impact force on the energy absorption box 201 being transmitted to the trunk beam body 2 and the front longitudinal beam 203 respectively.

[0061] Furthermore, by placing the connecting flange 132 on the side of the second mounting plate 13 away from the first mounting plate 12, the connecting flange 132 can be positioned towards the front longitudinal beam 203, so as to connect the connecting flange 132 to the front longitudinal beam 203, thereby realizing the connection between the second mounting plate 13 and the front longitudinal beam 203, and thus realizing the connection between the transition structure 1 and the front longitudinal beam 203. For example, the second mounting plate 13 can be connected to the front longitudinal beam 203 through a connector.

[0062] In some embodiments, a third mounting plate 14 is also connected to the rear side of the mounting motherboard 11, at least a portion of the third mounting plate 14 being adapted to be inserted into the front longitudinal beam 203.

[0063] Specifically, at least a portion of the third mounting plate 14 is adapted to be inserted into the front longitudinal beam 203, thereby connecting the third mounting plate 14 to the front longitudinal beam 203 via insertion. This allows the connection between the transition structure 1 and the front longitudinal beam 203 to be achieved through the third mounting plate 14. Furthermore, by connecting the third mounting plate 14 to the rear side of the mounting main plate 11, the third mounting plate 14 can be positioned facing the front longitudinal beam 203, facilitating the insertion of at least a portion of the third mounting plate 14 into the front longitudinal beam 203. The third mounting plate 14 can be connected to the mounting main plate 11 by welding.

[0064] like Figures 3-4As shown, the third mounting plate 14 is constructed to extend longitudinally along the vehicle, thus giving the third mounting plate 14 a certain length. This increases the insertion and mating length between the third mounting plate 14 and the front longitudinal beam 203, improving the connection reliability between the two. Furthermore, the third mounting plate 14 is constructed as a hollow tube, which reduces the weight of the third mounting plate 14, thereby reducing the weight of the adapter structure 1 and the elephant trunk beam assembly 100. This facilitates the installation of the elephant trunk beam assembly 100 on the vehicle. At least a portion of the third mounting plate 14 can be constructed to adapt to the shape of the front longitudinal beam 203, so that at least a portion of the third mounting plate 14 can fit against the front longitudinal beam 203, further improving the connection reliability between the two.

[0065] In some embodiments, a support plate 15 is also connected to the rear side of the mounting motherboard 11, and the support plate 15 is supported below the third mounting plate 14.

[0066] Specifically, the support plate 15 is supported below the third mounting plate 14, thus connecting the support plate 15 and the third mounting plate 14. This connection can be achieved by welding, improving the reliability of the connection and consequently enhancing the structural strength and operational reliability of the third mounting plate 14. Furthermore, the support plate 15 is connected to the rear side of the mounting main plate 11, again by welding, to improve the reliability of the connection and ensure reliable fixation of the support plate 15, thereby improving its operational reliability. Simultaneously, the support plate 15 can be moved closer to the third mounting plate 14 to facilitate connection and provide reliable support for the third mounting plate 14.

[0067] In such Figure 2 and Figure 4 In the illustrated embodiment, the support plate 15 is connected between the second mounting plate 13 and the front longitudinal beam 203, thereby achieving the connection between the second mounting plate 13 and the front longitudinal beam 203. The support plate 15 can be welded to the second mounting plate 13, and the support plate 15 and the front longitudinal beam 203 are connected by a fourth connector 151. The fourth connector 151 can be an M10 bolt, meaning that the support plate 15 and the front longitudinal beam 203 are detachably connected. This facilitates the connection or separation of the support plate 15 and the front longitudinal beam 203, making it easy to replace the front longitudinal beam 203 if it fails. There are two fourth connectors 151, spaced apart, so that the front longitudinal beam 203 and the support plate 15 can be connected simultaneously at two locations through the two fourth connectors 151, which can improve the reliability and stability of the connection between the two.

[0068] Therefore, the first mounting plate 12, the second mounting plate 13, the third mounting plate 14 and the support plate 15 can all be welded to the main mounting plate 11, making the transition structure 1 a whole. This can improve the overall structural strength and operational reliability of the transition structure 1. Furthermore, the elephant trunk beam body 2 can be connected to the first mounting plate 12 and the second mounting plate 13 respectively, and the front longitudinal beam 203 can be connected to the third mounting plate 14 and the support plate 15 respectively. This allows the collision force acting on the anti-collision beam 202 to be transmitted to the front longitudinal beam 203 and the elephant trunk beam body 2 respectively through the energy absorption box 201, thereby increasing the transmission path of the collision force.

[0069] In some embodiments, in the projection along the vehicle's vertical direction, the angle between the collapsible segment 21 and the vehicle's longitudinal direction is α, and satisfies: 30°≤α≤50°; and / or, in the projection along the vehicle's longitudinal direction, the angle between the collapsible segment 21 and the vehicle's vertical direction is β, and satisfies: 30°≤β≤40°.

[0070] Specifically, at least a portion of the elephant trunk body 2 is a collapsible segment 21, and the collapsible segment 21 is constructed to be inclined outwards and upwards along the front-to-back direction, so that when the elephant trunk body 2 is subjected to an impact force, the collapsible segment 21 can simultaneously bend and deform upwards and backwards to absorb the impact force. Figure 5 As shown, in the projection along the vehicle's vertical direction, the angle between the crumple zone 21 and the vehicle's longitudinal direction is α. The crumple zone 21 can be constructed to extend at an angle relative to the vehicle's longitudinal direction. Furthermore, the crumple zone 21 can be constructed to extend at an angle from the inside to the outside in the front-rear direction, so that the crumple zone 21 can bend and deform backward to absorb the impact force. α is between 30° and 50°, that is, α can be 35°, 40°, or 45°, etc., to avoid the inclination angle of the crumple zone 21 relative to the vehicle's longitudinal direction being too small or too large. If it is too small, the extension length of the crumple zone 21 from the inside to the outside will be too short, which is not conducive to the bending deformation of the crumple zone 21. If it is too large, the extension length of the crumple zone 21 from the inside to the outside will be too long, which is not conducive to the rearward transmission of the impact force.

[0071] At the same time, such as Figure 6 As shown, in the projection along the vehicle's longitudinal direction, the angle between the crumple zone 21 and the vehicle's vertical direction is β. This allows the crumple zone 21 to be constructed to extend at an angle relative to the vehicle's vertical direction. Furthermore, the crumple zone 21 can be constructed to extend at an angle from the inside to the outside in the vertical direction, allowing the crumple zone 21 to bend and deform upwards to absorb the impact force. β is between 30° and 40°, i.e., β can be 34°, 36°, or 38°, etc., to avoid the crumple zone 21's angle of inclination relative to the vehicle's vertical direction being too small or too large. If it is too small, the length of the crumple zone 21 extending from the inside to the outside will be too short, which is not conducive to the bending and deformation of the crumple zone 21. If it is too large, the length of the crumple zone 21 extending from the inside to the outside will be too long, which is not conducive to the rearward transmission of the impact force.

[0072] In some embodiments, the elephant trunk body 2 includes a first connecting segment 22, a collapsible segment 21, and a second connecting segment 23 connected sequentially in the front-to-back direction. The first connecting segment 22 is used to connect with the transition structure 1, and the second connecting segment 23 is used to connect with the A-pillar. At least a portion of the cross-section of the collapsible segment 21 is circular. And / or, the elephant trunk body 2 is a hydraulic tube beam formed by a hydraulic process.

[0073] Specifically, the elephant trunk beam body 2 includes a first connecting section 22, a collapsible section 21, and a second connecting section 23. The first connecting section 22, the collapsible section 21, and the second connecting section 23 are connected in sequence, making the elephant trunk beam body 2 a whole. This improves the overall structural strength and operational reliability of the elephant trunk beam body 2. Connecting the first connecting section 22 to the transition structure 1 and the second connecting section 23 to the A-pillar allows the elephant trunk beam body 2 to be connected to the transition structure 1 and the A-pillar. This enables the force acting on the anti-collision beam 202 to be transmitted to the A-pillar through the elephant trunk beam body 2, thereby achieving the transmission and dissipation of the collision force. Furthermore, connecting the first connecting section 22, the collapsible section 21, and the second connecting section 23 in sequence along the front-to-back direction allows the elephant trunk beam body 2 to extend in the front-to-back direction. This facilitates the movement of the first connecting section 22 and the second connecting section 23 towards the transition structure 1 and the A-pillar, respectively, making it easier to connect the front and rear parts of the elephant trunk beam body 2 to the transition structure 1 and the A-pillar, respectively.

[0074] Meanwhile, by constructing at least a portion of the cross-section of the crumple zone 21 as a circular cross-section, or by constructing a portion of the cross-section of the crumple zone 21 as a circular cross-section, the efficiency of the elephant trunk beam body 2 in transmitting collision force can be improved, thereby enhancing the efficiency and reliability of transmitting and dissipating collision force. Furthermore, the crumple zone 21 can be made into a hollow structure, reducing its weight, which in turn reduces the weight of the elephant trunk beam body 2, and consequently reduces the weight of the elephant trunk beam assembly 100. This facilitates the installation of the elephant trunk beam assembly 100 on a vehicle. In actual installation, the circular cross-section can be set as an ellipse or an irregular circle, which can improve the flexibility of installation.

[0075] Furthermore, the elephant trunk-shaped body 2 is a hydraulic tube beam manufactured using a hydroforming process. Hydroforming refers to a shaping technology that uses liquid or molds to form a workpiece; it is also known as hydraulic forming. Hydroforming can form various complex parts and has advantages such as good surface quality, reduced processes, simplified molds, and no need for special stamping equipment. In this embodiment, the tube beam can be used as the raw material. By applying liquid pressure to the tube cavity and applying an axial load, it undergoes plastic deformation within a given mold cavity, causing the tube wall to adhere to the inner surface of the mold, thereby obtaining a part of the desired shape. It can integrally form hollow parts with irregular cross-sections and axes that are two-dimensional or three-dimensional curves.

[0076] Thus, the initial circular cross-section of the pipe can be formed into a rectangular, trapezoidal, elliptical, or other irregular closed cross-section. Furthermore, at least a portion of the cross-section of the collapsible section 21 can be constructed as a circular cross-section, and the first connecting section 22 and the second connecting section 23 can be set to other shapes. This allows the elephant trunk beam body 2 to be manufactured from a single pipe beam, avoiding welding points between the first connecting section 22, the collapsible section 21, and the second connecting section 23, ensuring the structural strength of the elephant trunk beam body 2, and reducing manufacturing steps and costs. Additionally, constructing the elephant trunk beam body 2 as a hydraulic pipe beam makes it a hollow columnar structure, thereby reducing the amount of material needed to manufacture the elephant trunk beam body 2 and lowering manufacturing costs.

[0077] Furthermore, it should be noted that in actual design, the energy-absorbing box 201 can be constructed with a grid-shaped cross section to increase the contact area and mounting points between the energy-absorbing box 201 and the adapter structure 1, thereby improving the connection reliability between the energy-absorbing box 201 and the adapter structure 1. The dimensions of the energy-absorbing box 201 can also be flexibly set, such as making the length of the energy-absorbing box 201 along the longitudinal direction of the vehicle 245mm and the length along the transverse direction of the vehicle 168mm. By reasonably designing the dimensions of the energy-absorbing box 201, the structural strength and operational reliability of the energy-absorbing box 201 can be improved.

[0078] Furthermore, when the collision force is transmitted to the front longitudinal beam 203 and the elephant trunk beam body 2 through the energy absorption box 201, it can be distributed according to the cross-sectional dimensions of the front longitudinal beam 203 and the elephant trunk beam body 2 along the vehicle's transverse direction. For example, the cross-sectional dimension of the front longitudinal beam 203 along the vehicle's transverse direction can be L1, and the cross-sectional dimension of the elephant trunk beam body 2 along the vehicle's transverse direction can be L2. For example, L1 can be 75mm, and L2 can be 39mm, etc., so that the collision force can be transmitted according to the ratio of L1 to L2, ensuring the effective transmission of the collision force.

[0079] This utility model also proposes a front assembly 200.

[0080] The front assembly 200 according to an embodiment of the present invention includes a front longitudinal beam 203, an energy-absorbing box 201, and an elephant trunk beam assembly 100 according to any of the above embodiments. The energy-absorbing box 201 is adapted to be connected to the rear side of the anti-collision beam 202. A transition structure 1 is connected to the rear side of the energy-absorbing box 201. The front end of the front longitudinal beam 203 and the front end of the elephant trunk beam body 2 are spaced apart and respectively connected to the rear side of the transition structure 1. Thus, the energy-absorbing box 201 can be connected to the front longitudinal beam 203 and the elephant trunk beam body 2 respectively through the transition structure 1, so that the energy-absorbing box acting on the anti-collision beam 202... The collision force can be transmitted to the front longitudinal beam 203 and the elephant trunk beam body 2 through the energy absorption box 201 respectively. The rear end of the front longitudinal beam 203 is connected to the front structure 204, and the rear end of the elephant trunk beam body 2 is connected to the A-pillar. This allows the collision force transmitted to the front longitudinal beam 203 and the elephant trunk beam body 2 to be further transmitted to the front structure 204 and the A-pillar respectively. This increases the transmission path of the collision force, improves the reliability of the transmission and dissipation of the collision force, and effectively reduces the transmission of the collision force into the passenger compartment. This can effectively improve the vehicle's collision performance and safety.

[0081] The front and rear ends of the front longitudinal beam 203 are connected to the energy-absorbing box 201 and the front structure 204, respectively. This makes the structural strength of the front and rear parts of the front longitudinal beam 203 stronger than that of the middle part. As a result, when the front longitudinal beam 203 is subjected to a collision force, the middle part of the front longitudinal beam 203 can absorb part of the collision force by deforming inward. At the same time, at least a part of the elephant trunk beam body 2 is constructed as a crumple section 21, and the crumple section 21 is constructed to be inclined from bottom to top and outward in the front-rear direction. When the elephant trunk beam body 2 is subjected to a collision force, the crumple section 21 can deform upward and backward at the same time to absorb part of the collision force. In this way, when the front of the vehicle is involved in a collision, this part of the structure can deform inward, upward and backward at the same time to absorb the collision force, which can improve the overall stability while efficiently transmitting the collision force.

[0082] This utility model also proposes a vehicle.

[0083] The vehicle according to an embodiment of the present invention includes the front bulkhead assembly 200 described in the above embodiment. By setting the front bulkhead assembly 200, the transmission path of the collision force can be increased, the reliability of the transmission and dissipation of the collision force can be improved, and the transmission of the collision force into the passenger compartment can be effectively reduced, thereby effectively improving the vehicle's collision performance and safety. At the same time, during the transmission of the collision force from front to back, the middle part of the front bulkhead longitudinal beam 203 can deform inward to absorb part of the collision force, and the crumple zone 21 can deform upward and backward simultaneously to absorb part of the collision force. Thus, when a collision occurs at the front of the vehicle, this part of the structure can deform inward, upward and backward simultaneously to absorb the collision force, thereby improving the overall stability while efficiently transmitting the collision force.
