[0060] 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 1-13 The front compartment structure 100 according to the embodiments of the present application is described below.

[0061] Referring to Figure 1 and Figure 2 The front compartment structure 100 of the first aspect of the present application includes a longitudinal beam 10, a reinforcing member 20, and a side beam 30. The reinforcing member 20 is connected to the outer wall of the longitudinal beam 10, and the front end of the side beam 30 is connected to the reinforcing member 20. The side beam 30 extends from its front end towards the upper rear. The side beam 30 is an integrally formed thermal expansion tube.

[0062] Specifically, the side beam 30 in the front compartment structure 100 is fixedly connected to the longitudinal beam 10 through the reinforcing member 20, which can improve the connection strength of the side beam 30 and the longitudinal beam 10, thereby improving the safety of the front compartment structure 100 in the offset collision condition when responding to the front collision.

[0063] The reinforcing member 20 is connected to the outer wall of the longitudinal beam 10, which can provide support for the reinforcing member 20 and fix the reinforcing member 20, thereby preventing the reinforcing member 20 from shifting. The front end of the side beam 30 is connected to the reinforcing member 20, which can improve the connection strength of the front end of the side beam 30 and the reinforcing member 20, and also prevent the front end of the side beam 30 from being separated from the longitudinal beam 10 when subjected to a collision.

[0064] Moreover, the side beam 30 is formed as an integrally-molded thermal expansion tube, and the side beam 30 is formed as a thermal expansion tube with a closed cross section, so that the strength is high, and the barrier can be effectively supported when a collision occurs, thereby preventing intrusion. The side beam 30 extends from the front end thereof toward the upper rear, and when a force is applied, the force applied to the side beam 30 can be transmitted toward the upper rear, thereby playing a role in attenuating the external force.

[0065] Moreover, the side beam 30 is formed as an integrally-molded thermal expansion tube, so that the problem of tearing of a weld point when a collision occurs can be prevented, the directness of force transmission when a collision occurs can be ensured, and the problem of stress concentration due to multi-plate tailor welding can be avoided.

[0066] Thus, the side beam 30 and the longitudinal beam 10 in the front compartment structure 100 are fixedly connected by the reinforcement 20, so that the connection strength of the side beam 30 and the longitudinal beam 10 can be improved, and the front end of the side beam 30 can be prevented from being separated from the longitudinal beam 10 when a collision occurs, thereby improving the safety of the front compartment structure 100 in a crash.

[0067] According to some embodiments of the present application, as shown in Figure 2 The front end of the side beam 30 extends into the mounting cavity 21.

[0068] The front end of the side beam 30 extending into the mounting cavity 21 can increase the energy absorption capacity when a collision occurs, and the mounting cavity 21 can serve as an energy absorption cavity, thereby effectively absorbing the impact force of the front end of the side beam 30.

[0069] Moreover, compared with the conventional welding method of the side beam 30 and the longitudinal beam 10, the design of the mounting cavity 21 with the open top can make the side beam 30 more easily inserted and fixed in place, can reduce the complex assembly steps, and can facilitate subsequent maintenance. In addition, the mounting cavity 21 with the open top formed in the reinforcement 20 can effectively reduce the weight, thereby achieving lightweight design.

[0070] According to some embodiments of the present application, as shown in Figure 2 The front compartment structure 100 further includes a first fastener 22, and the first fastener 22 is arranged to pass through the longitudinal beam 10, the reinforcement 20, and the front end of the side beam 30, thereby connecting the longitudinal beam 10, the reinforcement 20, and the front end of the side beam 30.

[0071] The first fastener 22 can be a bolt, and the first fastener 22 can be arranged to pass through the reinforcement 20, the front end of the side beam 30, and the longitudinal beam 10 in sequence, so that the reinforcement 20, the front end of the side beam 30, and the longitudinal beam 10 can be more stably and firmly connected.

[0072] According to some embodiments of the present application, as shown in Figure 2and Figure 3 As shown in the drawings, the front cabin structure 100 further comprises: a first sleeve 23, the first sleeve 23 is arranged at the front end of the side beam 30, the outer end of the first sleeve 23 protrudes from the outer wall of the side beam 30, and the outer end of the first sleeve 23 is provided with a flange part 231, and the first fastener 22 is arranged through the first sleeve 23.

[0073] The outer end of the first sleeve 23 protrudes from the outer wall of the side beam 30, which facilitates the arrangement of the first fastener 22, and the outer end of the first sleeve 23 is provided with a flange part 231, which can enhance the pull-out force of the first fastener 22 and the first sleeve 23, and can avoid the pull-out risk caused by the weld failure.

[0074] According to some embodiments of the present application, as shown in the drawings, Figure 2 As shown in the drawings, the reinforcing member 20 comprises: a reinforcing body 24 and a side support rib 25, the reinforcing body 24 is formed with a mounting cavity 21, and the side support rib 25 is connected to the rear wall of the reinforcing body 24 and inclinedly approaches the longitudinal beam 10 in the front-to-back direction.

[0075] The reinforcing body 24 is formed with a plurality of mounting cavities 21, which not only facilitates the insertion of the front end of the side beam 30, but also forms an energy absorption cavity, thereby further absorbing the impact force of the front end of the side beam 30 and further improving the strength of the reinforcing member 20.

[0076] Further, the side support rib 25 is inclinedly close to the longitudinal beam 10 in the front-to-back direction, which can further improve the strength between the reinforcing body 24 and the longitudinal beam 10, and can provide support to the reinforcing body 24 by the longitudinal beam 10. At the same time, the side support rib 25 can play a role in collision force transmission, for example, the force received by the front end of the side beam 30 can be transmitted to the longitudinal beam 10 through the side support rib 25, and can also play a role in protecting the side beam 30.

[0077] According to some embodiments of the present application, as shown in the drawings, Figure 2 and Figure 3 As shown in the drawings, the reinforcing member 20 further comprises: a connecting rib 26 and a second fastener 27, the connecting rib 26 is connected between the rear wall of the reinforcing body 24 and the side support rib 25, a cavity with a triangular cross section is formed between the reinforcing body 24, the side support rib 25 and the connecting rib 26, and the second fastener 27 is arranged through the connecting rib 26 and the longitudinal beam 10, thereby connecting the connecting rib 26 and the longitudinal beam 10.

[0078] Further, the longitudinal beam 10 is provided with a nut plate, the second fastener 27 can be a bolt, the second fastener 27 is arranged through the longitudinal beam 10, the nut plate and the nut in sequence and is screwed, thereby further stabilizing and firmly connecting the connecting rib 26 and the longitudinal beam 10.

[0079] The connecting rib 26 is connected between the rear wall of the reinforcing body 24 and the side support rib 25, which can increase the strength between the reinforcing body 24 and the side support rib 25. The reinforcing body 24, the side support rib 25 and the connecting rib 26 form a cavity with a triangular cross section, so that a triangular stable structure can be formed, which can prevent the reinforcing member 20 from being deflected and can also avoid the premature failure of the side beam 30.

[0080] According to some embodiments of the present application, the reinforcing member 20 is an aluminum profile formed in one piece.

[0081] Compared with traditional steel, the aluminum profile can greatly reduce the weight under the condition of providing the same strength, so that the lightweight design of the reinforcing member 20 can be realized.

[0083] The middle beam segment 32 is arranged in a circular arc relative to the front beam segment 31 and the rear beam segment 33 in the vertical and horizontal directions, which on the one hand is to make the side beam 30 smoothly transition in the vertical direction and avoid stress concentration, and on the other hand is to make the center point of the circular arc located at the shock absorber mounting portion 80, so that the first force transmission rib 81 radiating to the shock absorber mounting portion 80 can be facilitated.

[0085] In addition, the front beam segment 31, the middle beam segment 32 and the rear beam segment 33 can be provided with a rectangular cross section with different circumferences, which can avoid increasing the adapter bracket, resulting in complex structure and weight increase. For example, the middle beam segment 32 is easily stressed, and the cross section of the middle beam segment 32 can be larger than that of the front beam segment 31 and the rear beam segment 33, so that the bending strength of the side beam 30 can be improved.

[0086] According to some embodiments of the present application, as shown in Figure 1 A first transition circular arc 40 for vertical transition is formed between the front beam segment 31 and the middle beam segment 32.

[0119] Further, the front end of the wheelhouse support rod 93 is connected to the inner side of the shock absorber mounting portion 80, and the rear end of the wheelhouse support rod 93 is connected to the front apron 92, so that the force between the shock absorber mounting portion 80 and the front apron 92 can be transmitted according to the wheelhouse support rod 93.

[0120] The rear ends of the wheelhouse support rods 93 on the two sides in the transverse direction, that is, the width direction of the vehicle, are arranged on the front apron 92, so that the force of the wheelhouse support rods 93 on the two sides in the transverse direction can be transmitted through the front apron 92, thereby achieving the transmission of the force on the two sides in the width direction of the vehicle.

[0121] In this way, sufficient support force can be further provided, so that the front compartment structure 100 can be prevented from deforming toward the central axis in the width direction of the vehicle, and the front compartment structure 100 can be pushed away from the obstacle when a collision occurs.

[0123] The longitudinal beams 10 on the two sides are in the shape of an eight, and the included angle between the longitudinal beam 10 and the central axis in the width direction of the vehicle can be set to 3.5°. When the front anti-collision beam 94 is subjected to force, the front anti-collision beam 94 can transmit the force to the energy absorption box 95 for absorption. The width of the energy absorption box 95 is greater than the width of the longitudinal beam 10, so that the contact area of the energy absorption box 95 with the longitudinal beam 10 and the obstacle can be increased, and the force can be reduced. Moreover, the rear end of the energy absorption box 95 is connected to the longitudinal beam 10 and the reinforcing member 20, respectively, so that the force of the energy absorption box 95 can be transmitted to the two sides in the width direction of the vehicle through the longitudinal beam 10 and the reinforcing member 20, thereby reducing the impact on the A-pillar.
