[0010] Optionally, the edge portion of the mounting member is connected to the front bulkhead body, and the remaining portion of the mounting member, except for the edge portion, is recessed toward the side away from the front bulkhead body to enclose and form the hollow beam structure with the front bulkhead body.

[0011] Optionally, multiple mounting components are arranged sequentially along the left-right direction of the vehicle.

[0012] Optionally, the front bulkhead body is provided with an air conditioning inlet, and the plurality of mounting components include a first mounting component, a second mounting component and a third mounting component arranged in sequence.

By placing the mounting component on one side of the front bulkhead body, such as the side facing the front of the vehicle, and connecting the mounting component to the front bulkhead body, the rigidity of the front bulkhead body is improved, which in turn improves the rigidity of the mounting base for the thermal management module. In addition, the mounting component is recessed away from the front bulkhead body, i.e., towards the front of the vehicle, to form a closed hollow beam structure with the front bulkhead body.

Therefore, they should not be construed as limitations on this invention.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a front bulkhead assembly according to an embodiment of the present invention includes a front bulkhead body 1 and a mounting member 2. The mounting member 2 is disposed on one side of the front bulkhead body 1 and is connected to the front bulkhead body 1. The mounting member 2 is recessed toward the side away from the front bulkhead body 1 to form a closed hollow beam structure 3 between itself and the front bulkhead body 1. The side of the mounting member 2 away from the front bulkhead body 1 is used to install a thermal management module 5.

[0031] Specifically, the front bulkhead body 1 is located between the passenger compartment and the engine compartment to isolate the passenger compartment and the engine compartment. It extends roughly along the left and right direction of the vehicle. The mounting part 2 can be located in front of the front bulkhead body 1, that is, on the side in the positive direction of the X-axis. The mounting part 2 is an integral structural component, specifically a sheet metal part. The mounting part 2 can be connected to the front bulkhead body 1 by welding or bolting. The mounting part 2 can be stamped to make it recessed in the direction away from the front bulkhead body 1, that is, in front of the vehicle. In this way, a closed hollow beam structure 3 can be formed between the mounting part 2 and the front bulkhead body 1.

[0032] The shape and quantity of the mounting component 2 are not limited. It can be designed according to the shape of the thermal management module 5 that needs to be fixed, ensuring that there are enough mounting points on the mounting component 2 for the thermal management module 5 to be connected.

[0033] In this embodiment, by providing a mounting member 2 on one side of the front bulkhead body 1 and connecting the mounting member 2 to the front bulkhead body 1, the rigidity of the front bulkhead body 1 is improved, which also improves the rigidity of the mounting base of the thermal management module 5. In addition, the mounting member 2 is recessed in a direction away from the front bulkhead body 1 to form a closed hollow beam structure 3 with the front bulkhead body 1. Since the closed hollow beam structure 3 has a large cross-sectional dimension and the material is concentrated at the edge of the section, it has a strong resistance to bending and torsional deformation. When the closed hollow beam structure 3 is subjected to external force, it can better maintain its shape stability, thereby improving the rigidity of the front bulkhead assembly. This ensures the installation stability of the thermal management module 5, reduces the vibration and noise of the thermal management module 5 during vehicle operation, and improves the NVH (Noise, Vibration, and Harshness) performance of the vehicle.

[0034] like Figures 4-6 As shown, optionally, the front bulkhead body 1 has a bent edge 11 that bends toward the side of the mounting member 2 at one end facing the vehicle, and the mounting member 2 has a first flange 21 that is parallel to the bent edge 11 at one end facing the vehicle, and the first flange 21 is connected to the bent edge 11.

[0035] Specifically, the end of the front bulkhead body 1 facing upwards on the vehicle, that is, the end along the positive Z-axis, is bent towards the mounting member 2 to form a bent edge 11. The bent edge 11 is generally horizontal. The end of the mounting member 2 facing upwards on the vehicle, that is, the end along the positive Z-axis, is bent away from the front bulkhead body 1 to form a first flange 21. By setting the bent edge 11 at the upper end of the front bulkhead body 1 and the first flange 21 at the upper end of the mounting member 2, the front bulkhead body 1 can be smoothly connected to the mounting member 2 through the bent edge 11 and the first flange 21. By using the first flange 21 and the bent edge 11 to be parallel and welded together, the contact area between the upper end of the mounting member 2 and the front bulkhead body 1 can be increased, and the installation stability between the mounting member 2 and the front bulkhead body 1 can be improved.

[0036] like Figure 4 and Figure 6 As shown, optionally, the mounting component 2 has a second flange 22 at at least one end along the left-right direction of the vehicle, and the second flange 22 is attached and connected to the front bulkhead body 1.

[0037] Specifically, the mounting component 2 has a second flange 22 at least at one end along the left-right direction of the vehicle, that is, the direction shown by the Y-axis, including three cases: the mounting component 2 has a second flange 22 at one end along the positive direction of the Y-axis, the mounting component has a second flange 22 at one end along the negative direction of the Y-axis, and the mounting component 2 has a second flange 22 at both ends along the direction shown by the Y-axis.

[0038] Taking the example of mounting component 2 having a second flange 22 at one end facing the positive Y-axis, mounting component 2 is bent along the positive Y-axis to form the second flange 22. The second flange 22 is parallel to and welded to the corresponding portion of the front bulkhead body 1, increasing the contact area between mounting component 2 and the front bulkhead body 1 in the left-right direction, thus improving the installation stability between mounting component 2 and the front bulkhead body 1. The second flange 22 may include multiple sub-flaps, which are welded to the front bulkhead body 1 respectively, providing multi-point connection and better stability.

[0039] In this embodiment, with the upper end of the mounting component 2 connected to the upper end of the front bulkhead body 1 via the first flange 21, the connection stability between the mounting component 2 and the front bulkhead body 1 is further improved by forming a second flange 22 at the end of the mounting component 2 along the left-right direction of the vehicle and connecting it to the front bulkhead body 1 using the second flange 22.

[0040] like Figures 1-5 As shown, optionally, the front bulkhead assembly also includes a front bulkhead crossbeam 4, which is installed on the end of the front bulkhead body 1 facing downwards from the vehicle. The end of the mounting member 2 facing downwards from the vehicle is provided with a third flange 23, which is attached to and connected to the front bulkhead crossbeam 4.

[0041] Specifically, the front bulkhead crossbeam 4 is located at the end of the front bulkhead body 1 facing downwards from the vehicle, that is, at the end of the front bulkhead body 1 facing the negative Z-axis. The front bulkhead crossbeam 4 extends roughly along the left-right direction of the vehicle. The front bulkhead crossbeam 4 and the front bulkhead body 1 can be fixed by welding or bolts.

[0042] By providing a front bulkhead crossbeam 4 extending in the left and right direction at the lower end of the front bulkhead body 1, the lower end rigidity of the front bulkhead body 1 can be improved; the lower end of the mounting part 2 can be bent toward the rear and lower part of the vehicle to form a third flange 23. By using the third flange 23 to be parallel to and welded to the corresponding part of the front bulkhead crossbeam 4, the contact area between the lower end of the mounting part 2 and the front bulkhead crossbeam 4 can be increased, thereby improving the installation stability between the mounting part 2 and the front bulkhead crossbeam 4.

[0043] like Figures 4-5 As shown, optionally, the third flange 23 is inserted between the front bulkhead beam 4 and the front bulkhead body 1, and the two opposite surfaces of the third flange 23 are respectively connected to the front bulkhead beam 4 and the front bulkhead body 1. The third flange 23 is fixed to both the front bulkhead beam 4 and the front bulkhead body 1, so that the force on the mounting component 2 can be simultaneously transmitted to the front bulkhead beam 4 and the front bulkhead body 1. The overall force on the front bulkhead assembly is more evenly distributed, which is beneficial to improving the installation stability of the thermal management module 5 and making it less prone to vibration and noise.

[0044] Optionally, the edge portion of the mounting member 2 is connected to the front bulkhead body 1, and the remaining portion of the mounting member 2, except for the edge portion, is recessed toward the side away from the front bulkhead body 1, so as to enclose the hollow beam structure 3 with the front bulkhead body 1.

[0045] Specifically, by connecting the four edges of the mounting member 2 to the front bulkhead body 1, the remaining part of the mounting member 2, excluding the edges, that is, the middle part of the mounting member 2, is recessed towards the side away from the front bulkhead body 1, so as to form a hollow beam structure 3 between the mounting member 2 and the front bulkhead body 1. This allows the hollow beam structure 3 to be set as large as possible, ensuring the rigidity of the whole formed by the front bulkhead body 1 and the mounting member 2. The mounting member 2 can be a long structure that extends roughly along the vertical direction of the vehicle, that is, the hollow beam structure 3 can be set to extend roughly along the vertical direction of the vehicle, thereby improving the vertical rigidity of the front bulkhead assembly.

[0046] like Figures 2-3 As shown, optionally, a plurality of the mounting components 2 are arranged sequentially along the left-right direction of the vehicle.

[0047] Specifically, multiple mounting components 2 are provided, that is, the thermal management module 5 is connected to the front bulkhead body 1 through multiple mounting components 2, so that the force on the front bulkhead body 1 is more evenly distributed, ensuring the installation stability of the thermal management module 5 on the front bulkhead body 1.

[0048] like Figures 1-2 As shown, optionally, the front bulkhead body 1 is provided with an air conditioning inlet 12, and the plurality of mounting parts 2 include a first mounting part, a second mounting part and a third mounting part arranged in sequence. The second mounting part and the third mounting part are respectively located on both sides of the air conditioning inlet 12. The first mounting part and the second mounting part are used to connect with the water-cooled condenser assembly 51 of the thermal management module 5, and the third mounting part is used to connect with the high-pressure coolant heater assembly 52 of the thermal management module 5.

[0049] Specifically, the air conditioning inlet 12 is usually located in the middle of the front bulkhead body 1 and is relatively large, resulting in poor rigidity around the air conditioning inlet 12 of the front bulkhead body 1, forming a weak point in rigidity. The first mounting component, the second mounting component, and the third mounting component may have different shapes and may be arranged in order from right to left. By positioning the second mounting component and the third mounting component on the left and right sides of the air conditioning inlet 12 respectively, the rigidity of the weak point can be strengthened.

[0050] The first and second mounting components can be connected to the water-cooled condenser assembly 51 of the thermal management module 5, respectively, and the third mounting component can be connected to the high-pressure coolant heater assembly 52 of the thermal management module 5. That is, different components of the thermal management module 5 are connected to the front bulkhead body 1 via corresponding mounting components 2, making the installation of the thermal management module 5 more secure and reliable. Furthermore, due to the relatively large size and shape of the water-cooled condenser assembly 51, connecting it simultaneously to the first and second mounting components ensures the installation stability of the water-cooled condenser assembly 51.

[0051] like Figures 2-4 As shown, optionally, the upper or lower end of the second mounting member is bent and extended toward the side closer to the first mounting member; and / or, each of the plurality of mounting members 2 is provided with a protrusion 24 for connection with the thermal management module 5.

[0052] Specifically, the first and second mounting components are used to jointly mount the water-cooled condenser assembly 51. The upper or lower end of the second mounting component bends towards the side closer to the first mounting component, allowing the second mounting component to be as close as possible to both the air conditioning inlet 12 and the first mounting component, thus maximizing the number of connection points on the second mounting component that can connect to the water-cooled condenser assembly 51. Furthermore, whether the upper or lower end of the second mounting component bends towards the first mounting component can be selected based on the arrangement requirements of the mounting points on the water-cooled condenser assembly 51.

[0053] Part of the mounting component 2 can protrude toward the side away from the front bulkhead body 1 to form a reinforcing boss. The protruding post 24 is welded to the reinforcing boss. The protruding post 24 can be provided with external threads. The protruding post 24 is inserted into the corresponding mounting hole of the thermal management module 5 and the nut is tightened to realize the connection between the thermal management module 5 and the mounting component 2.

[0054] Weight reduction holes can also be provided on mounting component 2 to reduce weight and material usage.

[0055] Another embodiment of this utility model provides a vehicle including the aforementioned front bulkhead assembly. The advantages of this vehicle compared to the prior art are the same as those of the aforementioned front bulkhead assembly, and will not be repeated here.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
