[0064] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0065] According to the first aspect of the present application, referring to Figure 1 The present disclosure provides a protection assembly, including: a water tank column 210 and an elephant trunk bridge 500, and the elephant trunk bridge 500 is fixedly connected to the water tank column 210.

[0066] The trunk is located at the front of the vehicle, usually in the engine compartment, close to the front bumper and front longitudinal beam. It is mainly used to support the components in the engine compartment, especially the water tank and radiator, to ensure that these components remain stable during the driving process of the vehicle. The radiator column is usually located at the front of the vehicle, specifically in the engine compartment, close to the front bumper and front longitudinal beam. The radiator column can support the water tank, ensuring that the water tank remains stable during the driving process of the vehicle and is not affected by vibration and impact. In the event of a collision, the radiator column can also deform, absorb part of the collision energy, reduce the impact on the cockpit, and thus protect the occupants of the cockpit.

[0067] In the related art, it is often necessary to use a large number of connectors to connect the water tank column and the trunk bridge. The use of a large number of connectors leads to high costs and excessive weight.

[0068] In the present application, the trunk bridge 500 is fixedly connected to the water tank column 210, rather than connecting the water tank column and the trunk bridge through a connecting piece. Compared with the solution of using more connecting pieces to connect the water tank column and the trunk bridge in the related art, the cost is lower and the weight is also lighter. In addition, by directly fixing the trunk bridge to the water tank column, the trunk bridge can better absorb the energy transmitted to the water tank column and can also better protect the water tank column.

[0069] In some embodiments, reference Figure 1The protection assembly also includes a secondary anti-collision beam 100 for supporting the thigh part of the pedestrian; the water tank pillar 210 includes a first end 211 and a second end 212 opposite to each other, the first end 211 is fixedly connected to the secondary anti-collision beam 100, and the second end 212 is fixedly connected to the trunk beam 500.

[0070] For taller vehicles, such as SUVs and pickup trucks, the secondary anti-collision beam 100 will collide with the thigh of the pedestrian during a collision. In order to prevent the pedestrian's knee joint from bending at a large angle during a collision, which may cause a fracture of the pedestrian, the support of the secondary anti-collision beam 100 on the thigh of the pedestrian is particularly important. In order to support and fix the secondary anti-collision beam 100, the first end 211 of the water tank column 210 is fixedly connected to the secondary anti-collision beam 100.

[0071] The first end 211 can be used as an upper joint of the water tank column 210 , and the second end 212 can be used as a lower joint of the water tank column 210 .

[0072] In addition, the secondary anti-collision beam 100 mainly transmits force through the water tank column 210, so the structural strength of the first end 211 and the second end 212 of the water tank column 210 is particularly critical. The water tank column 210 is a support member for fixing the secondary anti-collision beam. There is a long force arm between the first end 211 of the fixed position of the water tank column 210 and the second end 212 where the lower joint of the water tank column 210 is located. After being stressed, it is easy to generate a large turning moment and cause instability, resulting in insufficient support for the legs, and even unreasonable deformation of the legs. In addition, since the first end 211 cannot be reasonably arranged with a force transmission structure due to its location, it is also easy to become unstable.

[0073] In the present application, the first end 211 is fixedly connected to the secondary anti-collision beam 100, and the second end 212 is fixedly connected to the trunk bridge 500, so that the trunk bridge 500 is fixedly connected to the water tank column 210, so that the trunk bridge 500 strengthens the water tank column 210, prevents the water tank column 210 from being easily destabilized by a large turning moment after being subjected to force, and can provide more adequate support for the legs. In addition, since the water tank column and the trunk bridge are not connected by a connecting piece, the force transmission path is also reduced.

[0074] In some embodiments, reference Figure 1 The protection assembly further includes a sub-frame fixing seat 400 , and the sub-frame fixing seat 400 is fixedly connected to the second end 212 .

[0075] The sub-frame fixing seat 400 is used to provide a fixing point for the sub-frame. In these embodiments, the sub-frame fixing seat 400 is fixedly connected to the second end 212, so that the water tank column 210 can be strengthened.

[0076] In some embodiments, reference Figure 1The protection assembly further includes a longitudinal beam assembly 300, and the longitudinal beam assembly 300 is fixedly connected to the second end 212. In these embodiments, the longitudinal beam assembly 300 is fixedly connected to the second end 212, so that the water tank column 210 can be strengthened.

[0077] In some embodiments, reference Figure 1 The protection assembly further includes a front anti-collision beam 700 and an energy absorbing box 920. Along the Z direction of the vehicle, the front anti-collision beam 700 is located on the side of the secondary anti-collision beam 100 close to the second end 212. Along the X direction of the vehicle, one end of the energy absorbing box 920 is connected to the front anti-collision beam 700, and the other end opposite thereto is connected to the second end 212. In these embodiments, the energy absorbing box 920 is disposed between the front anti-collision beam 700 and the second end 212. When a collision occurs, the energy absorbing box 920 can collapse and deform to absorb energy.

[0078] In some embodiments, reference Figure 1 The protection assembly further includes an energy absorbing member 600 , which is mounted on the front anti-collision beam 700 . Along the X direction of the vehicle, at least part of the energy absorbing member 600 is located on a side of the front anti-collision beam 700 away from the water tank pillar 210 .

[0079] The front anti-collision beam 700 is located on the side of the secondary anti-collision beam 100 close to the second end 212. When a collision occurs, the front anti-collision beam 700 usually corresponds to the knee or calf of the pedestrian. An energy absorbing member 600 is arranged on the side of the front anti-collision beam 700 away from the water tank pillar 210. When a collision occurs, the energy absorbing member 600 first contacts the knee area or calf area of ​​the leg, and the energy absorbing member 600 deforms and collapses to absorb energy, thereby reducing the leg stress at the initial stage of contact.

[0080] In some embodiments, reference Figure 1 Along the X direction of the vehicle, at least part of the auxiliary anti-collision beam 100 is located on a side of the front anti-collision beam 700 away from the water tank pillar 210 .

[0081] When a collision occurs, the energy absorbing member 600 first contacts the knee area or the calf area of ​​the leg, and the energy absorbing member 600 deforms and collapses to absorb energy, reducing the stress of the leg at the initial stage of contact. Afterwards, the thigh part contacts the secondary anti-collision beam 100. Combined with the above, the secondary anti-collision beam 100 can provide sufficient front support force for the thigh part due to the reinforcement of the water tank pillar 210 and the trunk bridge 500.

[0082] In some embodiments, reference Figure 1 as well as Figure 7 The cross section of the energy absorbing member 600 may be set to be U-shaped, and the energy absorbing member 600 may be welded to the front anti-collision beam 700, for example, it may be welded to the front anti-collision beam 700 by two welding. The energy absorbing member 600 may be designed with multiple weight-reducing weakening holes.

[0083] In some embodiments, the energy absorbing member 600 may be an integral component. In some embodiments, the energy absorbing member 600 may be formed by splicing a plurality of plates.

[0084] The protection assembly in the embodiment of the present application can be applied to a vehicle with a load-bearing body, and various load-bearing mounting structures can be provided on the load-bearing body. Among them, a secondary anti-collision beam 100 and a front anti-collision beam 700 can be provided on such a body, wherein the secondary anti-collision beam 100 can be used as the main load-bearing support member for the thigh part of the pedestrian, and the front anti-collision beam 700 and the energy absorbing member 600 on the front anti-collision beam 700 can be used as the main support member for the calf part and the knee part. In the embodiment of the present application, by reasonably arranging the support structure members for the thigh and the calf, the requirements for pedestrian protection can be better achieved.

[0085] In some embodiments, reference Figure 1 The protection assembly further includes a radiator cross beam 230, which is located on the side of the secondary anti-collision beam 100 facing the radiator pillar 210 along the X direction of the vehicle, and the radiator cross beam 230 is connected to the first end 211. In these embodiments, the radiator cross beam 230 is connected to the first end 211, so that the radiator pillar 210 can be strengthened.

[0086] In some embodiments, please combine Figure 1 , Figure 6 as well as Figure 8 The secondary anti-collision beam 100 includes a supporting crossbeam 110 and a supporting longitudinal beam 120 . The supporting longitudinal beam 120 is located between the supporting crossbeam and the first end 211 . One end of the supporting longitudinal beam 120 is connected to the supporting crossbeam 110 , and the other end of the supporting longitudinal beam 120 is connected to the first end 211 .

[0087] The cross section of the support beam 110 may be hat-shaped. For example, the support beam 110 may include a first part 111, a second part 113 and a third part 115 that are bent and connected in sequence. The first part 111 and the third part 115 are relatively arranged, and the first part 111, the second part 113 and the third part 115 form a receiving space 116.

[0088] Specifically, it can be formed by a rolling process, which is low in cost. In some embodiments, a reinforcing rib can be provided in the middle of the cross section to further improve the bending rigidity along the Y direction of the vehicle. In some embodiments, the support crossbeam 110 and the support longitudinal beam 120 can adopt an embracing structure. For example, one end of the support longitudinal beam 120 can be installed in the accommodation space.

[0089] The support crossbeam 110 and the support longitudinal beam 120 can be fixedly connected by two-way welding, so that it is not easy to generate eccentric force during the impact process, which is beneficial to the stability of the structure. The support longitudinal beam 120 can be set as a closed beam. The secondary anti-collision beam 100 can also include a connecting plate 130. The end of the support longitudinal beam 120 away from the support crossbeam 110 is fixedly connected to one side of the connecting plate 130, and the other side opposite to the connecting plate 130 is connected to the first end. The support longitudinal beam 120 can first be connected to the connecting plate 130 by two-way welding, and then the connecting plate 130 is fixed to the water tank column 210 by screwing. The number of screw connections on the connecting plate can be designed according to demand. In order to ensure the connection strength, at least two can be set on one side. In addition, a stud can be welded to the first end 211 of the water tank column 210, so that it can be pre-fixed during assembly, thereby improving the convenience of assembly.

[0090] To ensure the strength of the screw connection, the connecting plate 130 needs to have sufficient rigidity. In some embodiments, the connecting plate 130 is designed to have a flanged structure. By adjusting the positions of the fixing points of the supporting longitudinal beam 120 and the water tank column 210 and lengthening the length of the supporting cross beam 110 as required, the requirement of covering the leg test area can be achieved.

[0091] In some embodiments, please combine Figure 1 as well as Figure 3 , since along the X direction of the vehicle, at least part of the secondary anti-collision beam 100 is located on the side of the front anti-collision beam 700 away from the water tank column 210. That is to say, at least part of the secondary anti-collision beam 100 is closer to the front of the vehicle than the front anti-collision beam 700, wherein the difference between the front and rear can be achieved by adjusting the supporting longitudinal beam 120, so as to better meet the requirements of collision. The height of the secondary anti-collision beam 100 is higher than the center of mass of the thigh, which can be achieved by adjusting the connection position of the supporting longitudinal beam 120 and the water tank column 210. For example, the connection position of the supporting longitudinal beam 120 and the water tank column 210 can be adjusted by adjusting the position of the screw connection point on the water tank column.

[0092] Please combine Figure 4 When the secondary anti-collision beam 100 supports the thigh part, the calf part still has a tendency to move to the rear of the vehicle. At this time, the energy absorbing member 600 on the front anti-collision beam 700 has been fully crushed, and the front anti-collision beam 700 begins to intervene to provide sufficient leg support. The force exerted on the front anti-collision beam 700 will be transmitted to the energy absorption box 920, the longitudinal beam assembly 300, the front cabin lower stabilizer bar 830, the radiator column 210, the trunk beam 500, and the radiator cross beam connecting plate 250, and can continue to transmit force to the rear of the vehicle. Finally, with the support of the secondary anti-collision beam 100 and the front anti-collision beam 700, pedestrian protection is achieved in the appropriate mode of leg deformation control.

[0093] In some embodiments, both ends of the front cabin lower stabilizing bar 830 may be screwed to fixing seats provided on the longitudinal beam assembly 300 , respectively, so as to realize the connection between the front cabin lower stabilizing bar 830 and the longitudinal beam assembly 300 .

[0094] In some embodiments, reference Figure 1 The supporting cross beam 110 and the radiator cross beam 230 both extend along the Y direction of the vehicle; there are two supporting longitudinal beams 120, and the two supporting longitudinal beams 120 are arranged along the Y direction of the vehicle; each supporting longitudinal beam 120 has at least a portion located between the supporting cross beam 110 and the radiator cross beam 230, which is used to connect the supporting cross beam 110 and the first end.

[0095] Please combine Figure 2 In these embodiments, the supporting crossbeam 110, the supporting longitudinal beam 120, and the radiator crossbeam 230 form a first annular structure, so that when the secondary anti-collision beam 100 is impacted, the force generated by the impact will be transmitted to the first annular structure, that is, after the supporting crossbeam 110 is impacted, the force will be transmitted to the supporting longitudinal beam 120 and then to the radiator crossbeam 230.

[0096] In some embodiments, the protection assembly further includes a radiator cross beam connecting plate 250 and a front cabin upper stabilizer bar 810. Along the X direction of the vehicle, the front cabin upper stabilizer bar 810 is located on the side of the radiator cross beam 230 away from the secondary anti-collision beam 100, and the radiator cross beam connecting plate 250 is located between the front cabin upper stabilizer bar 810 and the radiator cross beam 230. One end of the radiator cross beam connecting plate 250 is connected to the radiator cross beam 230, and the other end of the radiator cross beam connecting plate 230 is connected to the front cabin upper stabilizer bar 810. In this way, the radiator column 210 can be further strengthened.

[0097] In some embodiments, the front cabin upper stabilizer bar 810 extends along the Y direction of the vehicle, there are two radiator cross beam connecting plates 250, and the two radiator cross beam connecting plates 250 are arranged along the Y direction of the vehicle; each radiator cross beam connecting plate 250 is at least partially located between the radiator cross beam 230 and the front cabin upper stabilizer bar 810, and is used to connect the radiator cross beam 230 and the front cabin upper stabilizer bar 810.

[0098] Please combine Figure 2 In these embodiments, the front cabin upper stabilizer bar 810, the radiator cross beam connecting plate 250, and the radiator cross beam 230 form a second annular structure.

[0099] That is, after the first annular structure is subjected to an impact force, the impact force can be specifically transmitted to the second annular structure through the supporting crossbeam 110, the supporting longitudinal beam 120, and the radiator crossbeam 230. At this time, the impact force can be specifically transmitted through the radiator crossbeam 230, the radiator crossbeam connecting plate 250, and the front cabin upper stabilizer bar 810.

[0100] In some embodiments, along the X direction of the vehicle, the other end of the water tank cross beam connecting plate 230 is connected to the end of the trunk beam 500 away from the front anti-collision beam 700. In this way, the water tank pillar 210 can be strengthened.

[0101] In the related art, the trunk beam will overlap with the side of the longitudinal beam, and the trunk beam is not directly connected to the longitudinal beam connecting plate, and there is a certain distance from the energy absorption box. The longitudinal beam assembly will be welded to the subframe fixing seat first, then to the longitudinal beam connecting plate, and finally to the trunk beam.

The first end 211 can be located at the center point of the first annular structure, the second annular structure, the fourth annular structure, and the sixth annular structure 990, so that the impact force of the leg can be decomposed to each annular structure in time.

[0126] In the embodiment of the present application, the first end 211 of the radiator column 210 can be used as the upper joint of the radiator column 210.

[0127] According to a second aspect of the present disclosure, a vehicle is provided, the vehicle comprising the above-mentioned protection assembly. The vehicle has all the beneficial effects of the above-mentioned protection assembly, which will not be described in detail in the present disclosure.

[0128] Please combine Figure 2, the protection assembly in the embodiment of the present application can be applied to a vehicle with a load-bearing body, and various load-bearing mounting structures can be provided on the load-bearing body. The front compartment of this type of vehicle body is composed of multiple annular structures, which may specifically include the above-mentioned first annular structure, second annular structure, third annular structure, fourth annular structure, fifth annular structure 980, and sixth annular structure 990. Since the vehicle has multiple annular structures, the structure is more stable and can significantly improve the collision performance of the vehicle. The secondary anti-collision beam 100 is also strengthened, so that it can provide support for the thighs of pedestrians during the collision, reduce the bending angle of the knee joints of cars and pedestrians during the collision, and avoid injuries such as fractures to pedestrians. The connection stiffness of the first end 211 of the water tank column 210 is also increased, and the connection stiffness of the second end 212 of the water tank column 210 is increased. The ability of the water tank column 210 to resist flipping is improved, and it is not easy to flip up and down, ensuring the stability of the upper support, while having the effects of lightweight and low cost. In addition, since the radiator column 210 is organically integrated with other parts of the vehicle body and a multi-ring structure is formed, the force transmission efficiency is improved, the rigidity of the upper and lower structures is improved, thereby improving the support stability of the legs and avoiding unreasonable deformation of the legs.

[0129] After the secondary anti-collision beam 100 supports the thigh part, the calf part still has a tendency to move toward the rear of the vehicle. At this time, the energy absorbing member 600 on the front anti-collision beam 700 has been fully crushed, and the front anti-collision beam 700 begins to intervene to provide sufficient leg support.

[0130] The force is transmitted to the sixth ring structure 990 through the fifth ring structure 980 and continues to be transmitted to the rear of the vehicle. Finally, under the support of the secondary anti-collision beam 100 and the front anti-collision beam 700, pedestrian protection is achieved in a suitable mode of leg deformation control. The vehicle can be a fuel vehicle, a plug-in hybrid vehicle or a new energy vehicle, etc., which is not specifically limited in the present disclosure.
