Abstract

[0002] In related technologies, since pure electric vehicles do not have the exhaust system of gasoline vehicles, they have eliminated the raised central tunnel structure and designed the entire floor as a flat structure. In some pure electric vehicles, the power battery is located under the floor. In order to accommodate the placement of the power battery, two baffles are added to the outer bottom of the front bulkhead. This area forms a horizontal triangular cavity. However, because the sheet metal of the front bulkhead and baffle structure itself is relatively thin and the cavity area is large, the structural strength of this area is insufficient and the deformation is large under the condition of high-speed collision of the whole vehicle, which can easily cause injury to the occupants. Summary of the Invention

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0034] The following is for reference. Figures 1-4 A reinforcing plate 300 for the front bulkhead is described according to an embodiment of the present invention.
[0035] The reinforcing plate 300 of the front bulkhead according to an embodiment of the present invention, such as Figures 1-2 As shown, the reinforcing plate 300 includes: a reinforcing plate body 30 and a connecting flange 40.
[0036] The reinforcing plate body 30 is supported between the front bulkhead 100 and the baffle assembly 200 of the vehicle 1000. The connecting flange 40 is connected to the reinforcing plate body 30, and the outer side of the connecting flange 40 is connected to the front bulkhead 100 and the baffle assembly 200 respectively. The reinforcing plate body 30 and / or the connecting flange 40 are provided with reinforcing ribs 50.
[0037] Specifically, the reinforcing plate body 30 is connected between the front bulkhead 100 and the baffle assembly 200 via a connecting flange 40. The connecting flange 40 is connected to the front bulkhead 100 and the baffle assembly 200 via its outer side and to the reinforcing plate body 30. This allows the reinforcing plate body 30 to be connected to the front bulkhead 100 and the baffle assembly 200 as a whole, thereby strengthening the structural strength of the front bulkhead 100 and the baffle assembly 200. At the same time, the reinforcing plate body 30 and / or the connecting flange 40 are provided with reinforcing ribs 50, which can further enhance the structural strength of the reinforcing plate 300.
[0038] Therefore, the reinforcing plate 300 provided on the front bulkhead 100 can increase the structural strength of the front bulkhead 100 and the baffle assembly 200, making the front bulkhead 100 and the baffle assembly 200 less prone to deformation during a collision.
[0039] It should be noted that both the baffle assembly 200 and the reinforcing plate 300 are located on the outer side of the front bulkhead 100, with the baffle assembly 200 located on the outer side of the reinforcing plate 300. In related technologies, the baffle assembly 200 forms a transverse triangular cavity in the front bulkhead 100 to accommodate the arrangement of the power battery under the floor of the vehicle 1000, and the reinforcing plate 300 is installed in this cavity. In a vehicle collision, the baffle assembly 200 will be impacted first. The reinforcing plate 300 located in the cavity can provide support for the baffle assembly 200, making it less prone to deformation, and also reducing the probability of deformation of the front bulkhead 100 behind the reinforcing plate 300.
[0040] Therefore, in this invention, the reinforcing plate 300 is located in the cavity formed by the baffle assembly 200 and the front bulkhead 100. During a vehicle collision, the reinforcing plate 300 located in the cavity can support the baffle assembly 200 and the front bulkhead 100, making the baffle assembly 200 and the front bulkhead 100 stronger and less prone to deformation when impacted.
[0041] Furthermore, the reinforcing plate body 30 may be provided with reinforcing ribs 50, while the connecting flange 40 may not be provided with reinforcing ribs 50, or the connecting flange 40 may be provided with reinforcing ribs 50 while the reinforcing plate body 30 may not be provided with reinforcing ribs 50, or both the reinforcing plate body 30 and the connecting flange 40 may be provided with reinforcing ribs 50. In this embodiment, both the reinforcing plate body 30 and the connecting flange 40 are provided with reinforcing ribs 50.
[0042] Therefore, reinforcing ribs 50 are provided on the reinforcing plate body 30 and the connecting flange 40. The reinforcing ribs 50 can further enhance the structural strength of the reinforcing plate 300, so that the reinforcing plate 300 can better strengthen the baffle assembly 200 and the front panel 100.
[0043] According to an embodiment of the present invention, the reinforcing plate 300 of the front bulkhead can be installed between the front bulkhead 100 and the baffle assembly 200, so that the reinforcing plate 300 can enhance the structural rigidity of the area between the front bulkhead 100 and the baffle assembly 200. The reinforcing plate body 30 and / or the connecting flange 40 are provided with reinforcing ribs 50, which can further enhance the strength of the reinforcing plate 300, thereby further improving the structural rigidity of the area between the front bulkhead 100 and the baffle assembly 200 and reducing the deformation of the area under high-speed collision conditions of the vehicle.
[0044] In some embodiments, such as Figure 1 As shown, the reinforcing rib 50 includes a first reinforcing rib 51, and the reinforcing plate body 30 includes a first body portion 31 and a first reinforcing portion 32. The thickness of the first reinforcing portion 32 is greater than the thickness of the first body portion 31 to form the first reinforcing rib 51.
[0045] It is understandable that the thickness of the first reinforcing part 32 is greater than the thickness of the first body part 31, which will form a protrusion on the first body part 31. Thus, by increasing the thickness at this point, the protrusion formed is the first reinforcing rib 51. The first reinforcing rib 51 can enhance the structural strength of the reinforcing plate body 30. At the same time, the first reinforcing part 32 and the first body part 31 are integrally formed, which can improve production efficiency.
[0046] In some embodiments, such as Figures 1-2 As shown, the connecting flange 40 includes a first flange 41 and a second flange 42. The first flange 41 is welded to the baffle assembly 200, and the second flange 42 is bonded to the front bulkhead 100 by structural adhesive.
[0047] Specifically, during the connection of the reinforcing plate 300, the second flange 42 is first bonded to the front bulkhead 100 with structural adhesive, which fixes the reinforcing plate 300 to the front bulkhead 100. Then, the baffle assembly 200 and the first flange 41 are welded together. The reinforcing plate 300 is first bonded to the front bulkhead 100 with structural adhesive, which allows the position of the reinforcing plate 300 to be adjusted during connection.
[0048] Thus, the second flange 42 and the front panel 100 are bonded together with structural adhesive, so that the reinforcing plate 300 can be positioned accurately during installation. Then the first flange 41 is welded to the baffle assembly 200, making the connection more stable.
[0049] In some embodiments, such as Figure 1 As shown, the first flange 41 includes a first plate 411 and a second plate 412, and the baffle assembly 200 includes a front baffle 21 and a bottom baffle 22. The first plate 411 is connected to the front baffle 21, and the second plate 412 is connected to the bottom baffle 22.
[0050] It should be noted that the first plate 411 is connected to the front baffle 21. The first plate 411 is divided into two small plates. When the front baffle 21 is connected to the front panel 100, it has a bend, thus forming two surfaces. Therefore, the first plate 411 is divided into two small plates, which are connected to the two sides of the front baffle 21 that are bent out respectively. The second plate 412 is connected to the bottom baffle 22, so that the baffle assembly 200 can be better connected to the first flange 41.
[0051] Thus, the first plate 411 of the first flange 41 is connected to the front baffle 21, and the second plate 412 is connected to the bottom baffle 22, making the connection between the baffle assembly 200 and the first flange 41 better.
[0052] In some embodiments, such as Figure 1 As shown, the reinforcing rib 50 includes a second reinforcing rib 52, and the second plate 412 includes a second body portion 4121 and a second reinforcing portion 4122. The thickness of the second reinforcing portion 4122 is greater than the thickness of the second body portion 4121 to form the second reinforcing rib 52.
[0053] It is understandable that the thickness of the second reinforcing part 4122 is greater than the thickness of the second body part 4121. The second reinforcing part 4122 will form a protrusion on the second body part 4121, thereby forming a reinforcing rib 50. The second reinforcing rib 52 can increase the structural strength of the second plate 412, thereby enhancing the structural strength of the connecting flange 40.
[0054] Therefore, the second reinforcing rib 52 formed by the second reinforcing part 4122 makes the structure of the second plate 412 stronger and can provide better support for the baffle assembly 200. At the same time, the second reinforcing part 4122 and the second body part 4121 are integrally formed, which makes the processing efficiency higher.
[0055] In some embodiments, such as Figure 1As shown, the second plate 412 is provided with mounting holes 4123, which are suitable for fixedly engaging with the mounting frame of the power battery of the vehicle 1000.
[0056] It should be noted that in the relevant technology, the connection point of the power battery of some vehicles 1000 will pass through the front bulkhead 100 and be connected to the baffle assembly 200 at the front of the front bulkhead 100. The mounting hole 4123 provided on the second plate 412 coincides with the position of the connection point on the bottom baffle 22 in the baffle assembly 200, so that the power battery will also pass through the mounting hole 4123 of the second plate 412 when connected.
[0057] Therefore, while reinforcing the bottom baffle 22, the second plate 412 can also structurally strengthen the mounting frame of the power battery of the vehicle 1000, making the power battery installation more stable.
[0058] In some embodiments, such as Figure 1 As shown, the first plate 411, the second plate 412, and the second flange 42 are spaced apart in the circumferential direction of the reinforcing plate body 30.
[0059] It should be noted that the first plate 411, the second plate 412, and the second flange 42 are spaced apart on the circumferential direction of the reinforcing plate body 30. This results in more connection points when the reinforcing plate body 30 is connected to the baffle assembly 200 and the front panel 100, which can better fix the reinforcing plate 300 to the baffle assembly 200 and the front panel 100. At the same time, because the components are distributed on the circumferential direction, the reinforcing plate 300 will be subjected to more uniform stress, resulting in higher strength of the reinforcing plate 300.
[0060] In some embodiments, such as Figures 1-2 As shown, the connecting flange 40 is bent and connected to the reinforcing plate body 30.
[0061] It is understandable that the connecting flange 40 is bent and connected to the reinforcing plate body 30, thereby increasing the connection area between the connecting flange 40 and the baffle assembly 200 and the front panel 100, resulting in a better connection effect.
[0062] The present invention also proposes a front bulkhead assembly.
[0063] According to embodiments of the present invention, such as... Figure 2 As shown, it includes: a front bulkhead 100 and a baffle assembly 200, the baffle assembly 200 being mounted on the outside of the front bulkhead 100, and the baffle assembly 200 and the front bulkhead 100 defining a mounting cavity. A reinforcing plate 300, which is a reinforcing plate of the front bulkhead in any of the above embodiments, is mounted within the mounting cavity.
[0064] It should be noted that multiple reinforcing plates 300 can be installed in the mounting cavity of the front bulkhead assembly as needed, thereby further ensuring the structural strength of the front bulkhead assembly.
[0065] For example, when the lateral width of the mounting cavity of the current bulkhead assembly is further increased, multiple reinforcing plates 300 can be installed in the mounting cavity. The multiple reinforcing plates 300 are arranged in an array in the lateral direction of the mounting cavity, so that the multiple reinforcing plates 300 can further strengthen the structural strength of the front bulkhead assembly.
[0066] According to an embodiment of the present invention, a plurality of reinforcing plates 300 can be installed in the mounting cavity defined by the front bulkhead 100 and the baffle assembly 200. The plurality of reinforcing plates 300 further increase the strength of the front bulkhead assembly, making the front bulkhead assembly less prone to deformation.
[0067] The present invention also proposes a vehicle 1000.
[0068] The vehicle 1000 according to an embodiment of the present invention, such as Figure 4 As shown, it includes: the front bulkhead assembly of the above embodiment.
[0069] Preferably, the vehicle 1000 is an electric vehicle. In related technologies, its floor does not have a central tunnel structure, but a power battery needs to be placed on the floor. During the installation process, the connection point of the power battery will pass through the front bulkhead 100. Therefore, a baffle assembly 200 needs to be installed on the outside of the front bulkhead 100 to provide an installation area for the connection point of the power battery.
[0070] According to an embodiment of the present invention, a vehicle 1000 is equipped with a front bulkhead assembly as described above. In the front bulkhead assembly, a reinforcing plate 300 can be installed between the front bulkhead 100 and the baffle assembly 200, so that the reinforcing plate 300 can enhance the structural rigidity of the area between the front bulkhead 100 and the baffle assembly 200. The reinforcing plate body 30 and / or the connecting flange 40 are provided with reinforcing ribs 50, which can further enhance the strength of the reinforcing plate 300, thereby further improving the structural rigidity of the area between the front bulkhead 100 and the baffle assembly 200 and reducing the deformation of this area under high-speed collision conditions of the vehicle.
