Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and more specifically, to a mounting plate and an automobile. Background Art

[0002] With the popularization and development of new energy vehicles, the fire accidents of new energy vehicles have become a hot topic of concern. Among the fire accidents of new energy vehicles, the proportion of fire accidents caused by collisions is relatively high. At the same time, rear collisions of vehicles are relatively common. Once a collision occurs due to a rear collision or a rear-end collision, if the rear crossmember and the rear bumper cannot completely absorb the load received during the rear collision, it is very likely to squeeze some electrical components (such as a charger, a high-voltage and low-voltage converter, etc.) on the lower side of the vehicle tail, and there will be a risk of short circuit caused by the extrusion of the electrical components, and even a fire phenomenon may occur. Summary of the Utility Model

[0003] The utility model aims to improve the safety of electrical components under the vehicle tail.

[0004] To solve the above problems, the utility model provides a mounting plate, which includes a mounting main board.

[0006] When it is necessary to mount electrical components on the vehicle body structure, for example, when electrical components such as a charger and a high-voltage and low-voltage converter need to be mounted under the tail of the vehicle body structure, the electrical components can be mounted under the tail of the vehicle body structure through this mounting plate. That is, the mounting main board can be first fixed under the tail of the vehicle body structure, and then the electrical components can be mounted in the front area position under the mounting main board. Since a longitudinal strengthening structure is arranged on the mounting main board, the longitudinal strengthening structure can strengthen the strength and stiffness of the mounting main board in the longitudinal direction of the vehicle. Moreover, at least part of the longitudinal strengthening structure is located behind the electrical components. Thus, when a rear collision or a rear-end collision occurs to the vehicle, if structures such as the rear crossmember and the rear bumper of the vehicle cannot completely absorb the longitudinal load and deform forward, the part of the longitudinal strengthening structure located behind the electrical components can, to a certain extent, block the structures such as the rear crossmember and the rear bumper from continuing to deform forward, effectively avoiding the extrusion of the electrical components, and further reducing the risk of fire caused by the extrusion of the electrical components.

[0010] Further, on a first vertical plane perpendicular to the longitudinal direction of the vehicle, at least a part of the projection of the flanging structure coincides with the projection of the electrical component.

[0011] Further, at least two flanging structures are provided, and all the flanging structures are arranged at intervals in the transverse direction of the vehicle. The mounting main board is used for mounting at least two electrical components. Among them, on the first vertical plane, at least a part of the projection of each flanging structure coincides with the projection of the corresponding electrical component.

[0013] Further, one flanging structure and one electrical component are provided respectively;

[0014] Alternatively, one flanging structure is provided and at least two electrical components are provided. The mounting main board is used for mounting at least two electrical components.

Detailed Description of the Embodiment

[0026] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. Moreover, in the accompanying drawings, the X-axis represents the longitudinal direction, and the positive direction of the X-axis represents the front, and the negative direction of the X-axis represents the rear; the Y-axis represents the transverse direction, and the positive direction of the Y-axis represents the left, and the negative direction of the Y-axis represents the right; the Z-axis represents the vertical direction, that is, the up and down direction, and the positive direction of the Z-axis represents the upper, and the negative direction of the Z-axis represents the lower.

[0028] Meanwhile, it should be noted that the meanings represented by the foregoing X-axis, Y-axis, and Z-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0029] In the present utility model, unless otherwise specified, "a plurality of" means at least two.

[0030] Refer to Figures 1 - 3 , an installation plate according to an embodiment of the present utility model includes an installation main board 1. One side of the installation main board 1 is used for connecting with a vehicle body structure, and the other side of the installation main board 1 is used for installing electrical components 2. And a longitudinal strengthening structure 11 is arranged on the installation main board 1, and at least part of the longitudinal strengthening structure 11 is located at the rear side of the electrical components 2.

[0031] Among them, as Figure 3 shown, at least part of the longitudinal strengthening structure 11 being located at the rear side of the electrical components 2 means that at least part of the longitudinal strengthening ribs 11 is located on the side of the electrical components 2 in the negative X-axis direction, that is, at least part of the longitudinal strengthening ribs 11 is closer to the rear end of the vehicle than the electrical components 2.

[0032] In this embodiment, when it is necessary to install the electrical components 2 on the vehicle body structure, for example, when electrical components 2 such as a charger and a high and low voltage converter need to be installed under the rear part of the vehicle body structure, the electrical components 2 can be installed under the rear part of the vehicle body structure through this installation plate. That is, the installation main board 1 can be first fixed under the rear part of the vehicle body structure, and then the electrical components 2 can be installed at the front area position on the lower side of the installation main board 1.

[0033] Since the longitudinal strengthening structure 11 is arranged on the installation main board 1, the longitudinal strengthening structure 11 can strengthen the strength and stiffness of the installation main board 1 in the longitudinal direction of the vehicle. Moreover, at least part of the longitudinal strengthening structure 11 is located at the rear side of the electrical components 2. Thus, when a rear collision or a rear-end collision occurs to the vehicle, if structures such as the rear cross member and the rear bumper of the vehicle cannot completely absorb the longitudinal load and deform forward, the part of the longitudinal strengthening structure 11 located at the rear side of the electrical components 2 can, to a certain extent, block the structures such as the rear cross member and the rear bumper from continuing to deform forward, effectively preventing the electrical components 2 from being squeezed, and further reducing the risk of the electrical components 2 catching fire due to being squeezed.

[0034] It should be noted that the dimension of the installation main board 1 in the longitudinal direction of the vehicle is larger than the dimension of the electrical components 2 in the longitudinal direction. The electrical components 2 are installed in the front area position of the installation main board 1, and at least part of the longitudinal strengthening structure 11 on the installation main board 1 is located at the rear side of the electrical components 2. As a result, the area position of the installation main board 1 at the rear side of the electrical components 2 has relatively high strength and stiffness in the longitudinal direction; when the vehicle undergoes a rear collision or a rear-end collision, causing structures such as the rear cross member and the rear bumper to deform forward, due to the area position of the installation main board 1 at the rear side of the electrical components 2 having relatively high strength and stiffness in the longitudinal direction, the structures such as the rear cross member and the rear bumper that deform forward are difficult to force the area position of the installation main board 1 at the rear side of the electrical components 2 to also deform forward and squeeze the electrical components 2, thereby greatly reducing the risk of the electrical components 2 catching fire due to being squeezed.

[0035] See also Figures 1 - 3 Optionally, the longitudinal reinforcement structure 11 includes a longitudinal reinforcement rib 111 , and the longitudinal reinforcement rib 111 extends along the longitudinal direction of the vehicle, and at least a portion of the longitudinal reinforcement rib 111 is located on the rear side of the electrical component 2 .

[0036] In this embodiment, the longitudinal reinforcement structure 11 includes a longitudinal reinforcement rib 111. As the name implies, the longitudinal reinforcement rib 111 is a reinforcement rib extending in the longitudinal direction of the automobile to improve the strength and rigidity of the mounting main board 1 in the longitudinal direction. Moreover, at least part of the longitudinal reinforcement rib 111 is located at the rear side of the electrical component 2 to prevent the mounting main board 1 from deforming forward in the area located at the rear side of the electrical component 2 and squeezing the electrical component 2. In addition, by providing the reinforcement rib on the mounting main board 1 to enhance the rigidity of the mounting main board 1 in the longitudinal direction, the structure is relatively simple and the cost is low.

[0037] See also Figures 1 - 3 Optionally, a plurality of longitudinal reinforcing ribs 111 are provided, and the plurality of longitudinal reinforcing ribs 111 are spaced apart on the mounting main board 1 along the transverse direction of the vehicle (the Y-axis direction in the figure); and / or, along the longitudinal direction of the vehicle (the X-axis direction in the figure), one end of the longitudinal reinforcing rib 111 extends to the rear end of the mounting main board 1.

[0038] In this embodiment, a plurality of longitudinal reinforcing ribs 111 are provided, and the plurality of longitudinal reinforcing ribs 111 are spaced apart on the mounting main board 1 along the transverse direction of the automobile. Thus, by arranging the plurality of longitudinal reinforcing ribs 111 in this manner, it is possible to ensure that the rear area of ​​the mounting main board 1 at different transverse positions has a higher rigidity.

[0039] It should be noted that the rear area where the main board 1 is installed refers to the area where the main board 1 is installed behind the electrical component 2 .

[0040] In the present embodiment, one end of the longitudinal reinforcement rib 111, that is, the rear end of the longitudinal reinforcement rib 111, extends to the rear end of the mounting main board 1 to ensure that the longitudinal rigidity is increased as much as possible within the limited longitudinal dimension of the rear area of ​​the mounting main board 1, which is more beneficial for preventing the rear cross beam, rear bumper and other structures from continuing to deform forward.

[0041] Optionally, in the longitudinal direction of the vehicle, the front end of the longitudinal reinforcing rib 111 extends to the rear end of the electrical component 2 to maximize the length of the longitudinal reinforcing rib 111 at the rear area where the main board 1 is installed.

[0042] See also Figures 1 - 3, optionally, the upper side of the mounting main board 1 is used to connect with the rear floor of the vehicle body structure, and the lower side of the mounting main board 1 is used to mount the electrical components 2; the longitudinal strengthening structure 11 includes a flanging structure 112 disposed at the rear end of the mounting main board 1 and bent toward the side where the electrical components 2 are mounted.

[0043] In the prior art, since electrical components 2 such as chargers and high and low voltage converters are usually located under the rear floor of the vehicle body structure, in this embodiment, the mounting main board 1 is also mounted on the lower side of the rear floor, that is, the upper side of the mounting main board 1 is connected to the rear floor, and the lower side of the mounting main board 1 is used to mount the electrical components 2.

[0044] In this embodiment, the longitudinal strengthening structure 11 may further include a flanging structure 112 disposed at the rear end of the mounting main board 1, and the flanging structure 112 is bent toward the side where the electrical components 2 are mounted, that is, the flanging structure 112 is bent downward. Since the upper side of the mounting main board 1 is the rear floor, the flanging structure 112 can only be disposed downward. In addition, since the electrical components 2 are mounted on the lower side of the mounting main board 1, the downwardly disposed flanging structure 112 can also play a role in protecting the electrical components 2; moreover, the flanging structure 112 and the mounting main board 1 are an integrally formed structure, and there is an angle between them, for example, they are vertically disposed. This flanging structure 112 vertically disposed with the mounting main board 1 can further strengthen the longitudinal rigidity of the mounting main board 1, and ultimately can further reduce the risk of the electrical components 2 being extruded and catching fire.

[0045] See Figures 1 - 3 , optionally, on the first vertical plane (YZ plane) perpendicular to the longitudinal direction of the vehicle, at least part of the projection of the flanging structure 112 coincides with the projection of the electrical components 2.

[0046] In this embodiment, on the first vertical plane, at least part of the projection of the flanging structure 112 coincides with the projection of the electrical components 2, that is to say, at least part of the flanging structure 112 is located directly behind the high-voltage part. Thus, in the event of a rear collision, at least part of the flanging structure 112 can block the extrusion of other components at the rear (structures such as the rear cross member and the rear bumper) on the electrical components 2 directly in front, reducing the risk of high voltage generated during the collision.

[0047] See Figures 1 - 4 , optionally, one flanging structure 112 and one electrical component 2 are provided respectively;

[0048] Alternatively, one flanging structure 112 is provided, and at least two electrical components 2 are provided. The mounting main board 1 is used to mount at least two electrical components 2. Among them, on the first vertical plane, at least part of the projection of the flanging structure 112 coincides with the projection of each electrical component 2;

[0049] Alternatively, at least two of the flanging structures 112 and the electrical components 2 are provided. All the flanging structures 112 are arranged at intervals in the vehicle transverse direction. The mounting main board 1 is used to mount at least two of the electrical components 2. Wherein, on the first vertical plane, the projection of each of the flanging structures 112 at least partially coincides with the projection of the corresponding electrical component 2.

[0050] In the first solution of this embodiment, one flanging structure 112 and one electrical component 2 are provided respectively. It can be understood that on the first vertical plane, the projection of this one flanging structure 112 at least partially coincides with the projection of the electrical component 2.

[0051] In the second solution of this embodiment, as Figure 4 shown, one flanging structure 112 is provided, but at least two electrical components 2 can be sequentially mounted on the mounting main board 1 in the vehicle transverse direction. It can be understood that on the first vertical plane, the projection of this one flanging structure 112 at least partially coincides with the projections of the respective electrical components 2. In other words, the projections of the respective electrical components 2 at least partially coincide with the projection of this one flanging structure 112. That is to say, this one flanging structure 112 straddles all the electrical components 2 in its extending direction. Thus, this one relatively long flanging structure 112 can simultaneously play a role in protecting a plurality of electrical components 2.

[0052] In the third solution of this embodiment, as Figure 3 shown, at least two of the flanging structures 112 and the electrical components 2 are provided. For example, two of each are provided. These two flanging structures 112 are respectively a first flanging structure and a second flanging structure. At the same time, the mounting main board 1 has a relatively large size in the vehicle transverse direction. Two electrical components 2 can be both mounted on the mounting main board 1. The two electrical components 2 are respectively a first electrical component and a second electrical component. The first electrical component and the second electrical component can be arranged at intervals in the vehicle transverse direction in the front area position of the mounting main board 1. On this basis, on the first vertical plane, at least part of the first flanging structure coincides with the projection of the first electrical component, and at least part of the second flanging structure coincides with the projection of the second electrical component. Thus, the first flanging structure mainly plays a role in protecting the first electrical component, and the second flanging structure mainly plays a role in protecting the second electrical component.

[0053] Optionally, in the vehicle transverse direction, at least some of the longitudinal stiffening ribs 111 are located between the transverse two ends of the first electrical component; and / or, at least some of the longitudinal stiffening ribs 111 are located between the transverse two ends of the second electrical component; in other words, longitudinal stiffening ribs 111 are provided directly behind the first electrical component and the second electrical component. Further, good protection effects can be achieved for both of the two electrical components 2.

[0054] Among them, the first electrical component can be a charger, and the second electrical component can be a high-low voltage converter. Of course, in other embodiments, the electrical component 2 can also be other electrical components 2 with a risk of catching fire due to being squeezed.

[0055] It should be noted that as described above, the rear end of the longitudinal reinforcing rib 111 extends to the rear end of the mounting main board 1. It can be understood that in the case where there is a flanging structure 112 at the rear end of the mounting main board 1, the rear end of the longitudinal reinforcing rib 111 can extend to the corresponding flanging structure 112. In this way, through the connection between the longitudinal reinforcing rib 111 and the flanging structure 112, the longitudinal rigidity of the mounting main board 1 at the rear end can be further improved.

[0056] See Figures 1 - 3 , optionally, the mounting main board 1 is further provided with a transverse reinforcing rib 12, the transverse reinforcing rib 12 extends along the vehicle transverse direction, and in the horizontal plane, at least part of the projection of the transverse reinforcing rib 12 coincides with the projection of the electrical component 2.

[0057] In this embodiment, after the mounting main board 1 is fixed to the rear floor and the electrical component 2 is fixed to the mounting body, the transverse reinforcing rib 12 is mainly used to strengthen the dynamic stiffness at the mounting point of the electrical component 2. The analysis is as follows: When the vehicle is subjected to road excitation, especially when passing through a bumpy section, the vehicle body structure will generate a vertical load, and the vertical load will act on the mounting main board 1. Since the transverse dimension of the mounting main board 1 is larger than the longitudinal dimension, when the longitudinal load acts on the mounting main board 1, different positions of the mounting main board 1 in the transverse direction are likely to vibrate or even deform. In other words, the mounting main board 1 with a larger transverse dimension is like a "chopstick", and when this "chopstick" is subjected to a vertical load, the "chopstick" is likely to deform in its length direction (vehicle transverse direction). Therefore, by providing the transverse reinforcing rib 12, the deformation of the mounting board in the transverse direction can be effectively suppressed, and the dynamic stiffness at the mounting point of the electrical component 2 on the mounting main board 1 is improved.

[0058] In addition, since the longitudinal reinforcing rib 111 is provided at the rear part of the mounting main board 1 and the transverse reinforcing rib 12 is provided at the front part, it is also beneficial to improve the rigidity of the entire mounting board and the vehicle body structure.

[0059] See Figures 1 - 3 , optionally, a plurality of the transverse reinforcing ribs 12 are provided, and the plurality of transverse reinforcing ribs 12 are spaced apart along the vehicle longitudinal direction on the mounting main board 1, wherein, in the horizontal plane, at least part of the projection of each transverse reinforcing rib 12 coincides with the projection of the electrical component 2.

[0060] In this embodiment, a plurality of transverse reinforcing ribs 12 are sequentially arranged along the longitudinal direction of the vehicle at the front part of the mounting main board 1 to further improve the dynamic stiffness of the mounting points of the electrical components 2 on the mounting main board 1.

[0061] Among them, each transverse reinforcing rib 12 extends from one transverse end of the mounting main board 1 to the other transverse end of the mounting main board 1; when there are two electrical components 2, on the horizontal plane, at least part of the projection of each transverse reinforcing rib 12 coincides with the projections of the two electrical components 2 respectively, which can effectively improve the rigidity of the connection between the mounting main board 1 and each electrical component 2 and prevent the mounting main board 1 from deforming under the action of the gravity of the electrical components 2.

[0062] See Figures 2 - 3 , optionally, a boss structure 13 is provided on the mounting main board 1, and a boss connection hole 131 for mounting the electrical component 2 is provided at the boss structure 13.

[0063] In this embodiment, a boss structure 13 is provided on the mounting main board 1, and a boss connection hole 131 is provided on the boss structure 13 for mounting the electrical component 2. The setting of the boss structure 13 can further improve the rigidity of the mounting main board 1 and the electrical component 2. Among them, one electrical component 2 can be installed and fixed through the boss connection holes 131 at four boss structures 13, and the fixing effect is better. In addition, a plurality of vehicle body connection holes 14 can also be provided on the mounting main board 1, and the mounting main board 1 can be installed at the rear floor of the vehicle body structure through the plurality of vehicle body connection holes 14.

Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0067] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto.
