Description

Technical Field

[0001] This application relates to the automotive field, and in particular to an automotive front structure and vehicle. Background Technology

[0002] Currently, with increasing energy scarcity and growing public awareness of environmental protection, developing new energy vehicles has become a consensus. The global automotive market is seeing a surge in pure electric new energy vehicle models. Electric vehicles typically install their power batteries under the front floor. The central tunnel in the floor is a crucial component of the vehicle body, serving as one of the longitudinal force transmission mechanisms of the body frame. It bears the heavy responsibility of transmitting energy from front to rear, and together with components such as the door sill beams and seat crossbeams, forms a crisscrossing skeletal structure to ensure the body's rigidity and strength requirements, while also meeting the vehicle's service life and driving safety needs. Given the current limited battery unit capacity, the only way to increase battery capacity and extend driving range is to maximize the volume of the battery pack. Simultaneously, as people's living standards improve, their demands for vehicle comfort are also increasing, requiring more interior passenger space. This further compresses the front floor space from both above and below, further reducing the position of the central tunnel assembly, resulting in a "plate-like" floor layout. This significantly reduces the body's strength and rigidity, leading to uneven force transmission and seriously affecting vehicle safety.

[0003] The central tunnel in the floor reduces overall strength and rigidity due to limitations in battery size and interior space, and can lead to uneven force transmission within the vehicle. This issue urgently needs to be addressed to improve vehicle body rigidity and crash performance while still meeting space requirements. Utility Model Content

[0030] Please see Figure 1 and Figure 2 and Figure 3 This application provides a front bulkhead structure for automobiles, comprising a front bulkhead panel 1, a front floor 2, a first reinforcing structure 3, and a second reinforcing structure 4. The front bulkhead panel 1 and the front floor 2 are arranged sequentially in a first direction, wherein the direction in which the vehicle body extends is the first direction; the first reinforcing structure 3 is fixedly connected to the front bulkhead panel 1; the second reinforcing structure 4 is fixedly connected to the front floor 2; wherein the fixed connection of the first reinforcing structure 3 and the second reinforcing structure 4 transmits the external force received by the front bulkhead panel 1 to the front floor 2.

[0031] Specifically, in new energy vehicles, the front bulkhead 1 and the front floor 2 provide protection and support for the battery pack. The front bulkhead 1 is located at the front of the vehicle body, and the front floor 2 is connected to the front bulkhead 1. Simultaneously, the front bulkhead 1 is connected to the first reinforcing structure 3, and the front floor 2 is connected to the second reinforcing structure 4. Through the fixed connection of the first reinforcing structure 3 and the second reinforcing structure 4, after a collision, the external force received by the front bulkhead 1 is transmitted to the front floor 2 via the first reinforcing structure 3 and the second reinforcing structure 4, thus transferring the external force received by the front bulkhead 1 to the front floor 2. The application of the first reinforcing structure 3 and the second reinforcing structure 4 reduces the intrusion of the front bulkhead 1, improves the frontal collision performance of the vehicle, maintains the integrity of the passenger compartment, and ensures occupant safety.

[0032] In addition, the application of the first reinforcing structure 3 and the second reinforcing structure 4 can effectively reduce the intrusion of the front floor 2 structure deformation into the power battery pack, protect the battery pack from excessive compression during a collision, and thus prevent fire and explosion.

[0033] The application of the first reinforcing structure 3 and the second reinforcing structure 4 provides dual support, ensuring that even if one fails, the other can still transmit force, increasing reliability. This reduces the load distributed across the front floor 2 body, which helps to reduce the material and thickness requirements of the front floor 2, thus contributing to weight reduction.

[0034] Please continue reading. Figure 2 , Figure 3 and Figure 4 The first reinforcing structure 3 includes a first reinforcing plate 31, a first end of which is connected to the front bulkhead 1; and a second end of the first reinforcing plate 31 is connected to the second reinforcing structure 4. Specifically, the first reinforcing structure 3 includes a first reinforcing plate 31. The plate structure design helps to reduce the volume occupied, and the first reinforcing plate 31 is connected to the front bulkhead 1 and the second reinforcing structure 4 respectively, which achieves a good external force transmission effect.

[0035] In one embodiment, the first reinforcing plate 31 is made of ultra-high strength steel, which can effectively reduce the weight of the structure while ensuring its strength.

Specifically, since there is a height difference between the first reinforcing plate 31 and the front bulkhead 1, the first mounting plate 32 is used to connect the front bulkhead 1 and the first reinforcing plate 31, at which time the first mounting plate 32 is located between the front bulkhead 1 and the first reinforcing plate 31.

Figure 1 and Figure 2 The front structure of the vehicle also includes a torque box 5, which is connected to a portion of the first end of the first reinforcing plate 31. In new energy vehicles, the vehicle body is reinforced with components such as the torque box 5 to counteract the dynamic pressure caused by the weight of the battery. The first reinforcing plate 31, connected to the torque box 5, shares the external forces acting on the torque box 5, improving the frontal collision performance of the vehicle and ensuring occupant safety.

[0041] Please continue reading. Figure 2 , Figure 3 and Figure 6 The second reinforcing structure 4 includes a second reinforcing plate 41, a portion of which is connected to a first reinforcing plate 31; a portion of which is also connected to a torque box 5.

[0047] Please see Figure 3 The orthographic projection of the first reinforcing plate 31 on the front floor 2 and the orthographic projection of the second mounting plate 42 on the front floor 2 at least partially overlap. Specifically, the first reinforcing plate 31 is fixed to the front floor 2 by the second mounting plate 42 to ensure structural stability.

[0048] Please see Figure 3 The orthographic projection of the second reinforcing plate 41 on the front floor 2 and the orthographic projection of the second mounting plate 42 on the front floor 2 at least partially overlap. Specifically, both the second reinforcing plate 41 and the second mounting plate 42 are fixedly connected to the front floor 2, ensuring the overall structural stability of the second reinforcing structure 4.

[0049] Please continue reading. Figure 2 and Figure 6 The second reinforcing plate 41 includes at least one first reinforcing rib 421 extending along the first direction. The arrangement of the first reinforcing rib 421 increases the structural strength of the second reinforcing plate 41 and ensures its service life.

[0050] Please continue reading. Figure 2 and Figure 6 The second reinforcing plate 41 has at least one weight-reducing hole 422, which is located on the first reinforcing rib 421. The design of the weight-reducing hole 422 can reduce the weight of the structure and meet the lightweight requirements of the whole vehicle. At the same time, the weight-reducing hole 422 is located on the first reinforcing rib 421, which can reduce stress.

[0051] Please continue reading. Figure 2 and Figure 4 The first reinforcing plate 31 includes at least one second reinforcing rib 311 extending along a first direction. The provision of the second reinforcing rib 311 increases the structural strength of the first reinforcing plate 31 and ensures its service life.
