[0030] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.
[0031] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below. Figures 1-5 The front compartment structure of the vehicle body according to the embodiments of the present application is described, and the present application also proposes a vehicle.
[0032] The front compartment structure of the vehicle body according to the embodiments of the present application is described, and the present application also proposes a vehicle.
[0033] In addition, as shown in Figure 1 The front compartment assembly 100 includes a wheel cover body 10 and an elephant trunk beam 20, at least part of the elephant trunk beam 20 is arranged above the wheel cover body 10, and a cavity is formed between the elephant trunk beam 20 and part of the wheel cover body 10. Wherein, the wheel cover body 10 and the longitudinal beam 600 are connected.
[0034] The front compartment assembly 100 further includes a first reinforcing member 31, the first reinforcing member 31 is arranged in part of the cavity and is fixedly connected with the elephant trunk beam 20. The first reinforcing member 31 has a length extending through the entire elephant trunk beam 20, strengthens the strength of the elephant trunk beam 20, reduces the Y-direction crushing deformation, increases the X-direction crushing deformation, and increases the energy absorption. In addition, the first reinforcing member 31 can improve the Y-direction bearing capacity of the elephant trunk beam 20, enhance the X-direction bending deformation resistance, make the elephant trunk beam 20 produce greater X-direction crushing deformation, and improve the crashworthiness.
[0035] In addition, the front compartment assembly 100 further includes a second reinforcing member 32, one end of the second reinforcing member 32 is fixedly connected with the wheel cover body 10 and the other end is fixedly connected with the elephant trunk beam 20. The second reinforcing member 32 also plays a strong supporting role for the elephant trunk beam 20, further improves the Y-direction strength of the elephant trunk beam 20, reduces the Y-direction crushing deformation of the elephant trunk beam 20, increases the X-direction force transmission and deformation energy absorption of the elephant trunk beam 20. The first reinforcing member 31 can directly contact the inner wall of the cavity, produce bending and crushing deformation, increase the energy absorption of the elephant trunk beam 20, and reduce the subsequent damage to the passenger compartment.
[0036] And, the second reinforcement 32 increases the support of the wheel cover body 10, and improves the stability of the wheel cover body 10. In addition, the first reinforcement 31 in the elephant nose beam 20 gives the wheel cover body 10 a stronger support to the shock absorber, weakens the vibration and shaking of the front wheel cover and the shock absorber under poor road conditions, enhances the stability of the front wheel cover and the performance of the shock absorber, and improves the fatigue durability and comfort of the vehicle.
[0037] Further, since the first reinforcement 31 and the second reinforcement 32 are simple in structure, the forming process is relatively simple, easy to produce, and the construction cost is relatively low; and the above-mentioned first reinforcement 31 and second reinforcement 32 can be modified and improved according to different vehicle models, so it has strong applicability.
[0038] Therefore, by adding the first reinforcement 31 and the second reinforcement 32, the first reinforcement 31 and the second reinforcement 32 will produce X-direction bending, crushing deformation when colliding, directly participating in energy absorption; at the same time, the first reinforcement 31 and the second reinforcement 32 will transmit the collision force to the elephant nose beam 20 and the wheel cover body 10, indirectly increasing the energy absorption of other components.
[0039] In addition, referring to Figure 2 As shown, the elephant nose beam 20 includes an upper side beam cover plate 22 and a wheel cover longitudinal beam 21, the upper side beam cover plate 22 and the wheel cover longitudinal beam 21 are connected to each other and arranged above the first reinforcement 31, and the first reinforcement 31 is connected to the upper side beam cover plate 22 and the wheel cover longitudinal beam 21. That is, the first reinforcement 31 is connected to the upper side beam cover plate 22 and the wheel cover longitudinal beam 21, so that when the upper side beam cover plate 22 and the wheel cover longitudinal beam 21 are stressed, the stress can be transmitted to the first reinforcement 31, or when the first reinforcement 31 is stressed, the stress can be transmitted to the upper side beam cover plate 22 and the wheel cover longitudinal beam 21.
[0040] Wherein, one end of the upper side beam cover plate 22 away from the wheel cover longitudinal beam 21 is connected with the A-pillar reinforcement plate 500, and one end of the wheel cover longitudinal beam 21 away from the upper side beam cover plate 22 is connected with the bumper beam mounting plate, that is, the A-pillar reinforcement plate 500 and the bumper beam mounting plate are provided with the upper side beam cover plate 22 and the wheel cover longitudinal beam 21, so that when the vehicle is hit, the kinetic energy is transmitted from the front bumper beam, the bumper beam mounting plate, the upper side beam cover plate 22 and the wheel cover longitudinal beam 21 to the A-pillar reinforcement plate 500, thereby realizing the energy absorption of the front compartment structure.
[0041] In addition, one end of the first reinforcing member 31 is flush with one end of the cavity, and the other end of the first reinforcing member 31 is longer than the connection between the upper edge sealing plate 22 and the wheel cover longitudinal beam 21. That is, the first reinforcing member 31 is long enough to pass through the entire elephant trunk beam 20, and the lowermost end reaches the lowest position that the cavity of the elephant trunk beam 20 can reach, and the uppermost end is longer than the connection between the upper edge sealing plate 22 and the wheel cover longitudinal beam 21, thereby increasing the strength of the connection and preventing large bending deformation of the connection.
[0042] The bending shape of the first reinforcing member 31 is determined according to the shape of the elephant trunk beam 20 of the corresponding vehicle model. The shape of the first reinforcing member 31 can also be modified according to the size and shape of the cavity of the elephant trunk beam 20 of the vehicle model, but the designed shape must ensure that it has strong X-direction and Y-direction stiffness to reduce Y-direction crushing deformation and X-direction bending deformation of the elephant trunk beam 20.
[0043] As shown in Figure 1 and Figure 4 , the elephant trunk beam 20 includes the upper edge sealing plate 22, the wheel cover longitudinal beam 21, the wheel cover longitudinal beam 21 inner plate, and the wheel cover connecting plate 24. The upper edge sealing plate 22 and the wheel cover longitudinal beam 21 are connected to each other and are arranged above the first reinforcing member 31. The wheel cover longitudinal beam 21 inner plate and the wheel cover connecting plate 24 are connected to each other, and the wheel cover longitudinal beam 21 inner plate, the wheel cover connecting plate 24, and part of the wheel cover body 10 are arranged below the first reinforcing member 31. That is, the cavity is formed by the upper edge sealing plate 22, the wheel cover longitudinal beam 21, the wheel cover longitudinal beam 21 inner plate, the wheel cover connecting plate 24, and part of the wheel cover body 10. In this way, the collision force can be transmitted to the A-pillar reinforcing plate 500 through the elephant trunk beam 20 and the first reinforcing member 31, and the collision force can also be transmitted to the wheel cover body 10 through the second reinforcing member 32, that is, the Y-direction bearing capacity of the elephant trunk beam 20 can be improved, the X-direction bending deformation resistance can be enhanced, the X-direction crushing deformation can be increased, and the crashworthiness can be improved.
[0044] In addition, as shown in Figure 3 and Figure 4 , the elephant trunk beam 20 further includes the wheel cover longitudinal beam 21 inner plate and the wheel cover connecting plate 24, which are connected to each other and arranged below the first reinforcing member 31, and the other end of the second reinforcing member 32 is connected to the wheel cover connecting plate 24. That is, the second reinforcing member 32 is connected to the wheel cover connecting plate 24 of the elephant trunk beam 20. In this way, the second reinforcing member 32 can be connected between the wheel cover body 10 and the elephant trunk beam 20, thereby improving the participation degree and energy absorption value of the other side front compartment assembly 100 under small offset collision conditions, and increasing the energy absorption of the front compartment structure.
[0045] Referring to Figure 1As shown, an angle is formed between the second reinforcement 32 and the wheelhouse body 10 and the trunk beam 20. The first reinforcement 31 is installed at a certain angle between the wheelhouse body 10 and the trunk beam 20, directly connecting the wheelhouse body 10 and the inner plate of the wheelhouse longitudinal beam 21. The wheelhouse body 10 has relatively strong rigidity, while the trunk beam 20 has relatively weak rigidity in the Y direction. Therefore, the angle formed between the second reinforcement 32, the wheelhouse body 10 and the trunk beam 20 can greatly reduce the Y-direction crushing deformation of the trunk beam 20. While the collision load is transmitted to the A-pillar reinforcement plate 500 through the trunk beam 20, the collision force can also be transmitted to the wheelhouse body 10 through the second reinforcement 32, thereby increasing the collision force transmission path and improving the energy absorption of the front cabin structure.
[0046] Among them, the cross-sectional shape of the second reinforcement 32 can be appropriately improved according to the construction process requirements of different vehicle models, the layout of other structural parts installed nearby, and the installation requirements at both ends of the first reinforcement 31, but the designed shape must have strong rigidity and be able to play a strong supporting role.
[0047] Furthermore, the angle is an acute angle. That is to say, the angle is such that the second reinforcement 32, the wheel arch body 10, and the trunk bridge 20 form an isosceles triangle structure as much as possible, while ensuring that there is no interference with other structural parts. On the one hand, the triangular frame formed by the second reinforcement 32, the wheel arch body 10, and the trunk bridge 20 has strong rigidity. Even if subjected to lateral force, as long as the material itself is strong enough, the second reinforcement 32, the wheel arch body 10, and the trunk bridge 20 will not bend or tilt easily. On the other hand, the second reinforcement 32, the wheel arch body 10, and the trunk bridge 20 can effectively distribute the force applied thereto, thereby reducing local stress concentration and better resisting torsional and compressive forces.
[0048] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the front compartment structure of the vehicle body further comprises a stabilizer bar assembly 400 connected between the two wheel cover bodies 10, and further comprises two support rods 300 and a front apron 200, one end of each of the two support rods 300 being connected with the two wheel cover bodies 10, and the other end of each of the two support rods 300 being connected with each other and with the front apron 200. That is, a second reinforcing member 32 is added between the elephant trunk beam 20 and the wheel cover body 10, and the collision force can be transmitted to the wheel cover body 10 and the front compartment cross beam through the member, thereby increasing a complete force transmission path. In addition to the force transmission path of the elephant trunk beam 20 transmitting the collision force to the wheel cover body 10, the upper side beam cover plate 22 and the A-pillar reinforcing plate 500 through the elephant trunk beam 20, the collision force can also be transmitted to the wheel cover body 10, the stabilizer bar assembly 400 and the relevant load-bearing structure on the other side of the vehicle body through the second reinforcing member 32. According to the member, a complete force transmission path is formed between the structures on the left and right sides of the vehicle body, the participation degree and the energy absorption value of the structure on the other side under a small offset collision condition are improved, and the energy absorption capacity of the front compartment structure is increased.
[0049] That is, the collision force can be transmitted to the wheel cover body 10, the stabilizer bar assembly 400 through the second reinforcing member 32, or to the structure on the other side through the support rod 300, thereby increasing the collision force transmission path and improving the energy absorption of the front compartment structure.
[0050] Referring to Figure 1 As shown, the plane perpendicular to the height direction of the vehicle body is a first plane, and the included angle between the projection of the second reinforcing member 32 and the support rod 300 on the first plane is α, which satisfies the relationship: 0°≤α≤20°. That is, the included angle between the second reinforcing member 32 and the support rod 300 is small, or even 0. In this way, when the second reinforcing member 32 transmits the collision force to the wheel cover body 10, the small included angle between the second reinforcing member 32 and the support rod 300 enables the wheel cover body 10 to better transmit the collision force to the support rod 300, thereby realizing the transmission of the collision force to the relevant load-bearing structure on the other side of the vehicle body.
[0051] For example, the included angle between the second reinforcing member 32 and the support rod 300 is 0, that is, the second reinforcing member 32 and the support rod 300 are parallel to each other, thereby better transmitting the collision force to the relevant load-bearing structure on the other side of the vehicle body.
