[0066] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by reference to the accompanying drawings are exemplary and are intended to explain the present application, and are not to be understood as limiting the present application.

[0067] The mounting beam (hereinafter referred to as mounting beam 100) of an embodiment of the present application comprises a beam body 1, which can be a triangular structure, and the beam body 1 can be divided into a plurality of mounting areas 2, such as Figure 1As shown, the mounting area 2 can be provided with four, the four mounting areas 2 can be divided into two rows in the front-rear direction, the mounting area 2 located in the front row can be three, the three mounting areas 2 are respectively the first mounting area 21, the second mounting area 22, and the third mounting area 23, and the mounting area 2 located in the rear row can be only one, which is the fourth mounting area 24.

[0068] In use, the mounting beam 100 is assembled in the cabin body of the front cabin of the vehicle, and each mounting area 2 on the beam body 1 can mount different front cabin accessories (compressors, cooling modules, etc.), so that the accessories in the front cabin can be integrated, which is beneficial to simplify the mounting structure in the front cabin and improve the space utilization.

[0069] As shown, Figure 2 The beam body 1 includes a first cross beam 11, a second cross beam 12, a first inclined beam 13, and a second inclined beam 14, and the first cross beam 11, the second cross beam 12, the first longitudinal beam 161, and the second longitudinal beam 162 can all be linear. The first cross beam 11 and the second cross beam 12 are arranged in parallel and spaced apart, for example, the first cross beam 11 and the second cross beam 12 both extend along the left-right direction, and the first cross beam 11 is located on the front side of the second cross beam 12.

[0070] When assembling the mounting beam 100, the left end of the first cross beam 11 can be connected and fixed with the left shock tower 200 of the front cabin, and the right end of the first cross beam 11 can be connected and fixed with the right shock tower 300 of the front cabin. The left end of the second cross beam 12 can be connected and fixed with the left shock tower 200 of the front cabin, and the right end of the second cross beam 12 can be connected and fixed with the right shock tower 300 of the front cabin.

[0071] The first inclined beam 13 and the second inclined beam 14 are both arranged transversely to the second cross beam 12, one end of the first inclined beam 13 and one end of the second inclined beam 14 are both connected with the first cross beam 11, the other end of the first inclined beam 13 and the other end of the second inclined beam 14 are connected and form a first connection 15, and the first connection 15 is used to be connected with the front wall 400.

[0072] For example, as shown, Figure 2 The first inclined beam 13 and the second inclined beam 14 can be arranged in an eight-character shape, wherein the first inclined beam 13 can generally extend in the direction from the left front to the right rear, and the second inclined beam 14 can generally extend in the direction from the right front to the left rear. The front end of the first inclined beam 13 can be connected with the first cross beam 11, the rear end of the first inclined beam 13 can be connected with the rear end of the second inclined beam 14, and the front end of the second inclined beam 14 can be connected with the first cross beam 11.

[0073] The second crossbeam 12 can be integrally formed with the first inclined beam 13 and the second inclined beam 14, and together they form a triangular structure. The first crossbeam 11, the first inclined beam 13, and the second inclined beam 14 can form another triangular structure. Thus, the beam body 1 forms a continuous double-layer triangular frame structure.

[0074] When a vehicle is subjected to a small offset collision, such as Figure 1 As shown by the black arrows, the impact force can be transmitted along the first crossbeam 11, the first inclined beam 13, and the second crossbeam 12, enabling beam 1 to effectively disperse the impact energy. Furthermore, the double-layer triangular frame structure enhances the structural strength and stability of beam 1.

[0075] It should be noted that, as Figures 1 to 4 As shown, beam 1 can be a roughly symmetrical structure. The axis of symmetry of beam 1 extends roughly along the front-back direction and can pass through the midpoint of the first crossbeam 11 and the second crossbeam 12. This ensures the structural and force balance of the left and right sides of beam 1.

[0076] In this embodiment of the invention, the mounting beam 100, the first crossbeam 11 and the second crossbeam 12 can form two crossbeam connection paths for the vehicle, thereby significantly improving the crossbeam stiffness and torsional stiffness of the front compartment and enhancing driving safety.

[0077] Secondly, the double-layer triangular frame structure of beam 1 can effectively disperse collision energy. Combined with the inherent stability of the triangle, it also makes beam 1 structurally stronger and more stable.

[0078] In addition, by setting multiple installation areas 2 on the beam 1, some accessories in the forward compartment can be classified and integrated on the installation beam 100, making the installation beam 100 highly integrated. This can reduce the number of parts in the installation structure in the forward compartment and facilitate the lightweight design of the forward compartment. On the other hand, it can improve the overall assembly efficiency. During assembly, each accessory can be assembled on the corresponding sub-assembly line first, and then each accessory can be assembled on the installation beam 100 on the final assembly line. This can improve the installation accuracy and cycle time of the final assembly line and improve production efficiency.

[0079] In some embodiments, the beam body 1 includes a plurality of longitudinal beams 16, which are all connected between the first crossbeam 11 and the second crossbeam 12, and the plurality of longitudinal beams 16 are arranged at intervals along the transverse direction of the beam body 1.

[0080] For example, such as Figure 2As shown, the longitudinal beam 16 can be set within the space enclosed by the first crossbeam 11, the second crossbeam 12, the first longitudinal beam 161, and the second longitudinal beam 162. There can be two, three, four, five, or other longitudinal beams 16. Multiple longitudinal beams 16 can be arranged in parallel and spaced along the left-right direction, and each longitudinal beam 16 can extend along the front-back direction. The front end of each longitudinal beam 16 can be connected and fixed to the first crossbeam 11, and the rear end of each longitudinal beam 16 can be connected and fixed to the second crossbeam 12.

[0081] The longitudinal beam 16 connects the first crossbeam 11 and the second crossbeam 12, thereby further improving the structural strength and stability of the beam 1. On the other hand, the longitudinal beam 16 can also form a force transmission path, which is conducive to heat dissipation of collision energy and improves safety.

[0082] In some embodiments, the plurality of longitudinal beams 16 include a first longitudinal beam 161 and a second longitudinal beam 162, the first longitudinal beam 161, the second longitudinal beam 162, the first crossbeam 11, and the second crossbeam 12 forming a U-shaped structure, the U-shaped structure forming a first mounting area 21, and the front compartment accessory including a compressor, the compressor being mounted on the U-shaped structure.

[0083] For example, such as Figure 2 As shown, there can be only two longitudinal beams 16, namely the first longitudinal beam 161 and the second longitudinal beam 162, wherein the first longitudinal beam 161 can be located to the left of the second longitudinal beam 162. The first longitudinal beam 161, the second longitudinal beam 162, the first crossbeam 11, and the second crossbeam 12 can form a U-shaped structure, as shown. Figure 1 As shown, the U-shaped structure can form an installation area 2 (first installation area 21). During assembly, the air conditioner compressor can be directly fixed below the first installation area 21.

[0084] It should be noted that in related technologies, air conditioning compressors are typically fixed to an adapter bracket via shock-absorbing bushings, and then the adapter bracket is bolted to the connecting crossbeam. Compared with the compressor installation method in related technologies, this embodiment eliminates the adapter bracket. The air conditioning compressor is directly fixed between the first crossbeam 11 and the second crossbeam 12 of the mounting beam 100. Two longitudinal beams 16 are designed between the two crossbeams, forming a U-shaped structure, which greatly improves the dynamic stiffness and NVH modes of the air conditioning compressor.

[0085] In some embodiments, the U-shaped structure has a plurality of first mounting points 211, which are arranged at intervals along the circumference of the U-shaped structure, and the compressor is connected to the plurality of first mounting points 211. Figure 2As shown, the first mounting point 211 can be a hole-shaped connecting structure, and the first mounting point 211 can be provided in a number of three, four, five, etc. The plurality of first mounting points 211 can be arranged at intervals along the circumference of the mouth-shaped structure, thereby ensuring the assembly strength of the compressor and the beam body 1.

[0086] In some embodiments, as shown in Figure 2 As shown, the first mounting point 211 can be provided in three, and one first mounting point 211 can be provided on the first longitudinal beam 161 and the second longitudinal beam 162, and the first transverse beam 11 between the first longitudinal beam 161 and the second longitudinal beam 162. Thus, the three first mounting points 211 can form a triangular structure, thereby ensuring the structural stability of the fixed compressor.

[0087] Optionally, the mouth-shaped structure is provided with a plurality of shock-absorbing bushings, and the plurality of shock-absorbing bushings are provided at the plurality of first mounting points 211 one by one, and the compressor is assembled at the mouth-shaped structure through the shock-absorbing bushings. Thus, the buffering and shock-absorbing effect of the compressor can be achieved, and the rigid contact between the compressor and the beam body 1 is avoided.

[0088] In some embodiments, the plurality of mounting areas 2 includes a second mounting area 22 and a third mounting area 23, the first mounting area 21 is located between the second mounting area 22 and the third mounting area 23, and the second mounting area 22, the first mounting area 21, and the third mounting area 23 are sequentially arranged in the transverse direction of the beam body 1.

[0089] For example, as shown in Figure 1 and Figure 2 As shown, the second mounting area 22 can be provided on the left side of the first mounting area 21, and the first mounting area 21 can be formed by part of the first transverse beam 11, part of the second transverse beam 12, and part of the first inclined beam 13 on the left side of the first longitudinal beam 161. The third mounting area 23 can be provided on the right side of the first mounting area 21, and the third mounting area 23 can be formed by part of the first transverse beam 11, part of the second transverse beam 12, and part of the second inclined beam 14 on the right side of the second longitudinal beam 162.

[0090] The front cabin accessories include a cooling module and an expansion pot, one of the second mounting area 22 and the third mounting area 23 is used to install the cooling module, and the other is used to install the expansion pot. Specifically, the expansion pot can be installed in the second mounting area 22, and the cooling module can be installed in the third mounting area 23.

[0091] Thus, since the front half of the beam body 1 is longer in the left-right direction, by dividing the first mounting area 21, the second mounting area 22, and the third mounting area 23 in the front half of the beam body 1, the space on the beam body 1 can be fully utilized, the utilization rate is improved, and the integrated arrangement of the installation of the front cabin accessories is facilitated.

[0092] In some embodiments, the second mounting area 22 is provided with a plurality of second mounting points 221, which are arranged at intervals along the circumference of the second mounting area 22, and the third mounting area 23 is provided with a plurality of third mounting points 231, which are arranged at intervals along the circumference of the third mounting area 23.

[0093] Specifically, there may be three, four, five, or more second mounting points 221, and these multiple second mounting points 221 may be evenly distributed on the first crossbeam 11, the second crossbeam 12, and the first longitudinal beam 161. Similarly, there may be three, four, five, or more third mounting points 231, and these multiple third mounting points 231 may be evenly distributed on the first crossbeam 11, the second crossbeam 12, and the second longitudinal beam 162.

[0094] Therefore, on the one hand, the assembly structure strength of the expansion tank (cooling module) and beam 1 can be enhanced, and on the other hand, the vibration of the expansion tank (cooling module) can be directly transmitted to different beams, which helps to alleviate the vibration of the expansion tank.

[0095] In some embodiments, the plurality of mounting areas 2 includes a fourth mounting area 24, which is located on the side of the second crossbeam 12 away from the first crossbeam 11 and adjacent to the first connection 15.

[0096] For example, such as Figure 1 As shown, the fourth installation area 24 is located on the rear side of the beam 1, and the rear end portion of the first inclined beam 13 and the rear end portion of the second inclined beam 14 form the fourth installation area 24. The front cabin accessories may include an air conditioning motor body, which can be assembled in the fourth installation area 24, further improving the integrated arrangement of the front cabin accessories and the installation beam 100.

[0097] In some embodiments, the fourth mounting area 24 may be provided with a plurality of fourth mounting points 241, specifically three, four, five, six, etc., and the plurality of fourth mounting points 241 are arranged at intervals along the circumference of the fourth mounting area 24. This can enhance the structural strength of the assembly of the air conditioner motor body and the beam 1.

[0098] Optionally, there may be two fourth mounting points 241. A lug plate may be provided on the inner rear end of the first inclined beam 13 and the inner rear end of the second inclined beam 14, and the two lug plates shall form two fourth mounting points 241 respectively.

[0099] In some embodiments, one end of the first inclined beam 13 is connected to one end of the first crossbeam 11 to form a second connection 17, which is used to connect to the left damping tower 200. One end of the second inclined beam 14 is connected to the other end of the first crossbeam 11 to form a third connection 18, which is used to connect to the right damping tower 300.

[0100] For example, such asFigure 2 As shown, the front end of the first inclined beam 13 can be connected with the left end of the first horizontal beam 11 to form a second connection 17, and the front end of the second inclined beam 14 can be connected with the right end of the first horizontal beam 11 to form a third connection 18, so that the front end of the first inclined beam 13 and the left end of the first horizontal beam 11 share an installation point and can be fixed with the left shock tower 200 at the same time, and the front end of the second inclined beam 14 and the right end of the first horizontal beam 11 share an installation point and can be fixed with the right shock tower 300 at the same time.

[0101] On the one hand, the structural strength of the connection between the beam body 1 and the shock tower can be enhanced, and on the other hand, the force applied by the shock tower to the beam body 1 can be decomposed to the first horizontal beam 11 and the first inclined beam 13 (the second inclined beam 14), further improving the force decomposition effect.

[0102] In some embodiments, the material of the beam body 1 is aluminum, and the beam body 1 is integrally pressure cast. Specifically, the first horizontal beam 11, the second horizontal beam 12, the first inclined beam 13, the second inclined beam 14, and the plurality of longitudinal beams 16 can be processed and formed by high-pressure aluminum casting, so that on the one hand, the continuity and structural strength of the connection between the beams can be ensured, and on the other hand, the aluminum material is light in texture, and the lightweight of the beam body 1 can be realized.

[0103] In some embodiments, the top surface of the first inclined beam 13 and / or the top surface of the second inclined beam 14 is provided with a first rib group 19, and the first rib group 19 is located between the first connection 15 and the second horizontal beam 12. For example, as shown in Figure 7 and Figure 8 As shown, the first rib group 19 can be an X-shaped structure composed of two reinforcing ribs, and the top surface of the first inclined beam 13 and the top surface of the second inclined beam 14 can be integrally formed with a first rib group 19.

[0104] The bottom surface of the first inclined beam 13 and / or the bottom surface of the second inclined beam 14 is provided with a second rib group 110, and the second rib group 110 is located between the first connection 15 and the second horizontal beam 12. For example, as shown in Figure 8 As shown, the bottom surface of the first inclined beam 13 and the bottom surface of the second inclined beam 14 can be provided with a second rib group 110, and the second rib group 110 can be a field-shaped structure composed of a plurality of reinforcing ribs.

[0105] The first inclined beam 13 and / or the second inclined beam 14 is provided with a gap for avoiding the wiper envelope, and the first rib group 19 and the second rib group 110 can be arranged at the gap of the first inclined beam 13 or the second inclined beam 14, and the first rib group 19 and the second rib group 110 on the same inclined beam can be arranged in a vertical direction. In this way, the structural weakness caused by the gap for avoiding the wiper envelope can be compensated, the structural strength of the beam body 1 is ensured, and the use requirement is met. In addition, the carrying capacity in the structural collision process can be improved, and the vehicle safety is improved.

[0106] In some embodiments, the third rib group 111 is arranged at the position of the included angle formed by the first inclined beam 13 and the second transverse beam 12. Specifically, as shown in Figure 8 , the third rib group 111 can be arranged in the acute angle formed by the first inclined beam 13 and the second transverse beam 12, and the first inclined beam 13, the second transverse beam 12 and the third rib group 111 form a triangular structure. In this way, the rigidity of the connection between the first inclined beam 13 and the second transverse beam 12 can be improved.

[0107] In some embodiments, the fourth rib group 112 is arranged at the position of the included angle formed by the second inclined beam 14 and the second transverse beam 12. Specifically, as shown in Figure 8 , the fourth rib group 112 can be arranged in the acute angle formed by the second inclined beam 14 and the second transverse beam 12, and the second inclined beam 14, the second transverse beam 12 and the fourth rib group 112 form a triangular structure. In this way, the rigidity of the connection between the second inclined beam 14 and the second transverse beam 12 can be improved.

[0108] In some embodiments, as shown in Figure 4 and Figure 5 , the cross section of the first transverse beam 11 is Z-shaped. As shown in Figure 4 and Figure 6 , the cross section of the second transverse beam 12 is Z-shaped. In this way, the bending resistance of the second transverse beam 12 can be improved while meeting the die casting process of the first transverse beam 11 and the second transverse beam 12. The structure of the first transverse beam 11 and the second transverse beam 12 is also enhanced, which is beneficial to improve the compressor mounting point stiffness, reduce the compressor excitation noise, and improve the vehicle comfort.

[0109] In some embodiments, the top surface and the bottom surface of the beam body 1 are provided with a plurality of vertical ribs 113, and at least part of the vertical ribs 113 are high and low in the extension direction of the vertical ribs 113. Specifically, as shown in Figure 8As shown, the vertical ribs 113 can be integrally formed on the bottom surface of the beam body 1, and the vertical ribs 113 can include annular ribs and linear ribs, wherein the annular ribs can extend along the inner side edges and the outer side edges of the beam body 1 to form a ring. The linear ribs can be provided in multiple, and the corresponding linear ribs can extend along the first inclined beam 13, the second inclined beam 14, the first horizontal beam 11, the second horizontal beam 12, and each longitudinal beam 16. Thus, the structural strength and rigidity of the beam body 1 can be enhanced.

[0110] It should be noted that the height dimension of each vertical rib 113 in the up-down direction can vary in height along the extension direction of the vertical rib 113, and this variation can be determined by topology optimization design, so that the reinforced part (higher part) of the vertical rib 113 can correspond to the structure on the beam body 1 relative to the weaker area, so that the reinforced position of the vertical rib 113 is more targeted, and it is also beneficial to reduce the material consumption of the vertical rib 113, while improving the performance requirements, lightweight design can be realized.

[0111] In some embodiments, as Figures 1 to 4 As shown, the included angle formed by any two beams can be designed with a rounded transition, for example, the acute angle formed by the first inclined beam 13 and the first horizontal beam 11 can be rounded and transitioned, and the corresponding rounded diameter can be 60 mm. The acute angle formed by the second inclined beam 14 and the first horizontal beam 11 can also be rounded and transitioned, and the corresponding rounded diameter can also be 60 mm. The structural strength and rigidity of the connection between the two beams can be improved, and stress concentration can also be avoided.

[0113] The front compartment assembly of the embodiment of the application includes a mounting beam 100, which can be any of the mounting beams 100 described in the above embodiments. As Figure 9 As shown, the front compartment assembly includes a left shock tower 200 and a right shock tower 300, and the left end of the first horizontal beam 11 and the left end of the second horizontal beam 12 are connected to the left shock tower 200, and the right end of the first horizontal beam 11 and the right end of the second horizontal beam 12 are connected to the left shock tower 200.

[0114] The center point (which can be regarded as an axis) of the left shock tower 200 is located between the left end of the first horizontal beam 11 and the left end of the second horizontal beam 12, and the center point (which can be regarded as an axis) of the left shock tower 200 is located between the right end of the first horizontal beam 11 and the right end of the second horizontal beam 12. Thus, the rigidity of the left shock tower 200 (left shock tower 200) transverse (left-right direction) mounting point can be improved.

[0115] In some embodiments, the front compartment assembly comprises front compartment accessories which are assembled to the corresponding mounting areas 2 of the beam body 1, and the front compartment accessories comprise at least one of the following: a compressor, a cooling module, an expansion pot or an air conditioner motor body. The compressor can be fixed to the first mounting area 21, the expansion pot can be fixed to the second mounting area 22, the cooling module can be fixed to the third mounting area 23, and the air conditioner motor body can be fixed to the fourth mounting area 24.

[0116] In some embodiments, as shown in Figure 9 The front compartment assembly further comprises a front wall 400 which is connected and fixed to the first connection 15. The front side of the front wall 400 can be provided with a mounting base 401, and the rear end of the beam body 1 can be overlapped on the mounting base 401 and connected and fixed to the mounting base 401.

[0117] A vehicle of an embodiment of the present application is described below.

[0118] The vehicle of the embodiment of the present application comprises a front compartment assembly which can be any of the front compartment assemblies described in the above embodiments. The vehicle can be a car, an SUV, a pickup truck, a bus, etc., and of course can also be other vehicles with a front compartment assembly.

[0119] An installation beam optimization design method of an embodiment of the present application is described below.

[0120] The installation beam 100 optimization design method of the embodiment of the present application comprises the following steps:

[0121] S1: Create a body-in-white model with a design space of the installation beam 100. For example, a body-in-white model containing the entire installation beam design space can be made according to the positions and arrangement spaces of the various mounting points of the installation beam 100, and the model can be a finite element model.

[0122] S2: Determine the optimal force transmission path of the installation beam 100 in the design space through topology optimization. For example, topology optimization can be performed considering factors such as the dynamic stiffness of the compressor mounting point, the bending and torsional stiffness of the entire vehicle, and the local modal performance of the installation beam 100, so that the optimal force transmission path of the installation beam 100 in the design space can be obtained. The optimal force transmission path should be able to meet the dynamic stiffness performance while achieving lightweight design. When topology optimization is performed, structural size and process constraints can be considered so that the optimized structure meets the process requirements.

[0123] S3: Create an initial model of the mounting beam 100 according to the optimal force transmission path. For example, a product design engineer can create a mounting beam 100 structure (initial model) reflecting the optimal force transmission path according to the topological optimization, combined with process requirements and assembly arrangement requirements, etc. It should be noted that in the process of establishing the initial model, the thickness of the mounting beam 100 should also be optimized in combination with NVH dynamic stiffness, vehicle body bending and torsional stiffness, safety crash performance and other factors, so as to obtain a lightweight structure that meets various performances.

[0124] S4: Optimize the specific structure of the initial model and obtain the final model of the mounting beam 100.

[0125] The specific structure optimization design can include cross-section optimization design of the first cross beam 11 and the second cross beam 12. For example, the cross-section design of the second cross beam 12 after optimization can be a "Z" shaped cross-section, so as to improve the axial and bending load capacity of the beam, significantly reduce the noise transmission to the passenger's ear due to compressor excitation, and improve the comfort of the vehicle.

[0126] The specific structure optimization design can also include the arrangement position and structure optimization design of the reinforcing structure on the beam body 1. For example, "X" shaped and Chinese character shaped ribs can be designed on the beam body 1 according to the collision force transmission direction, so as to improve the load capacity of the beam, improve the cross-section force in the collision process, and improve the safety of the vehicle.

[0127] The specific structure optimization design can also include optimization of the shape and thickness of the reinforcing ribs on the beam body 1. For example, arc-shaped variable-thickness ribs can be designed at each connection or corner, thereby reducing the weight of the parts and achieving weight reduction and cost reduction of the parts under the condition of meeting the stiffness, NVH and safety performance.
