Detailed Implementation

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] The vehicle mounting beam (hereinafter referred to as mounting beam 100) of this invention includes a beam body 1, which can be a triangular structure and can be divided into multiple mounting areas 2, such as... Figure 1 As shown, there can be four installation areas 2. The four installation areas 2 can be divided into two rows in the front and back direction. There can be three installation areas 2 in the front row, namely the first installation area 21, the second installation area 22, and the third installation area 23. There can be only one installation area 2 in the back row, which is the fourth installation area 24.

[0042] In use, the mounting beam 100 is assembled into the front compartment of the vehicle, and different front compartment accessories (compressors, cooling modules, etc.) can be installed in the various mounting areas 2 on the beam 1. This allows the accessories in the front compartment to be integrated, which helps to simplify the installation structure in the front compartment and improve space utilization.

[0043] like Figure 2As shown, beam 1 includes a first crossbeam 11, a second crossbeam 12, a first inclined beam 13, and a second inclined beam 14. The first crossbeam 11, the second crossbeam 12, the first longitudinal beam 161, and the second longitudinal beam 162 can all be straight. The first crossbeam 11 and the second crossbeam 12 are arranged in parallel and spaced apart. For example, both the first crossbeam 11 and the second crossbeam 12 extend in the left-right direction, and the first crossbeam 11 is located in front of the second crossbeam 12.

[0044] When assembling the installation beam 100, the left end of the first crossbeam 11 can be connected and fixed to the left shock absorber tower 200 of the forward compartment, and the right end of the first crossbeam 11 can be connected and fixed to the right shock absorber tower 300 of the forward compartment. The left end of the second crossbeam 12 can be connected and fixed to the left shock absorber tower 200 of the forward compartment, and the right end of the second crossbeam 12 can be connected and fixed to the right shock absorber tower 300 of the forward compartment.

[0045] The first inclined beam 13 and the second inclined beam 14 are both arranged to cross 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 to 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 to form a first connection 15, which is used to connect to the front bulkhead 400.

[0046] For example, such as Figure 2 As shown, the first inclined beam 13 and the second inclined beam 14 can be arranged in a V-shape, wherein the first inclined beam 13 can generally extend from the front left to the rear right, and the second inclined beam 14 can generally extend from the front right to the rear left. The front end of the first inclined beam 13 can be connected to the first crossbeam 11, the rear end of the first inclined beam 13 can be connected to the rear end of the second inclined beam 14, and the front end of the second inclined beam 14 can be connected to the first crossbeam 11.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] For example, such as Figure 2 As 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.

[0055] 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.

[0056] 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.

[0057] For example, such as Figure 2As 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.

[0058] 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.

[0059] 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 2 As shown, the first mounting point 211 can be a hole-shaped connection structure. There can be three, four, five, or other numbers of first mounting points 211. Multiple first mounting points 211 can be arranged at intervals along the circumference of the U-shaped structure, thereby ensuring the assembly structural strength of the compressor and the beam 1.

[0060] In some embodiments, such as Figure 2 As shown, there can be three first mounting points 211: one at the connection between the first longitudinal beam 161 and the second crossbeam 12, one at the connection between the second longitudinal beam 162 and the second crossbeam 12, and one on the first crossbeam 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 compressor.

[0061] Optionally, the U-shaped structure is equipped with multiple shock-absorbing bushings, which are correspondingly installed at multiple first mounting points 211. The compressor is fitted to the U-shaped structure through the shock-absorbing bushings. This provides a buffering and shock-absorbing effect for the compressor, avoiding rigid contact between the compressor and the beam 1.

[0062] In some embodiments, the plurality of mounting areas 2 include a second mounting area 22 and a third mounting area 23, a 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 arranged sequentially in the transverse direction of the beam 1.

[0063] For example, such as Figure 1 and Figure 2 As shown, the second installation area 22 can be located to the left of the first installation area 21. The first installation area 21 can be formed by a portion of the first crossbeam 11, a portion of the second crossbeam 12, and a portion of the first diagonal beam 13 on the left side of the first longitudinal beam 161. The third installation area 23 can be located to the right of the first installation area 21. The third installation area 23 can be formed by a portion of the first crossbeam 11, a portion of the second crossbeam 12, and a portion of the second diagonal beam 14 on the right side of the second longitudinal beam 162.

[0064] The forward compartment accessories include a cooling module and an expansion tank. 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 tank. Specifically, the expansion tank can be installed in the second mounting area 22, and the cooling module can be installed in the third mounting area 23.

[0065] Therefore, since the front half of the beam 1 is relatively long in the left and right directions, dividing the front half of the beam 1 into a first installation area 21, a second installation area 22, and a third installation area 23 can make full use of the space on the beam 1, improve the utilization rate, and facilitate the integrated layout of the installation of front cabin accessories.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] In some embodiments, the plurality of mounting areas 2 include 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.

[0070] For example, such as Figure 1As 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] For example, such as Figure 2 As shown, the front end of the first inclined beam 13 can be connected to the left end of the first crossbeam 11 to form a second connection 17, and the front end of the second inclined beam 14 can be connected to the right end of the first crossbeam 11 to form a third connection 18. Thus, the front end of the first inclined beam 13 and the left end of the first crossbeam 11 can share a mounting point and be simultaneously connected and fixed to the left damping tower 200, and the front end of the second inclined beam 14 and the right end of the first crossbeam 11 can share a mounting point and be simultaneously connected and fixed to the right damping tower 300.

[0075] On the one hand, it can enhance the structural strength of the connection between the beam 1 and the damping tower. On the other hand, it can decompose the force exerted by the damping tower on the beam 1 into the first crossbeam 11 and the first inclined beam 13 (second inclined beam 14), further improving the force decomposition effect.

[0076] In some embodiments, the beam body 1 is made of aluminum and is integrally die-cast. Specifically, the first crossbeam 11, the second crossbeam 12, the first inclined beam 13, the second inclined beam 14, and multiple longitudinal beams 16 can all be formed by high-pressure aluminum casting. This ensures the continuity and structural strength of the connections between the beams, and the lightweight nature of aluminum allows for the weight reduction of the beam body 1.

[0077] In some embodiments, a first rib group 19 is provided on the top surface of the first inclined beam 13 and / or the top surface of the second inclined beam 14, the first rib group 19 being located between the first connection 15 and the second crossbeam 12. For example, as Figure 7 and Figure 8 As shown, the first rib group 19 can be an X-shaped structure composed of two reinforcing ribs. 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.

[0078] A second rib group 110 is provided on the bottom surface of the first inclined beam 13 and / or the bottom surface of the second inclined beam 14. The second rib group 110 is located between the first connection 15 and the second crossbeam 12. For example, as Figure 8 As shown, the bottom surface of the first inclined beam 13 and the bottom surface of the second inclined beam 14 can both be provided with a second rib group 110, and the second rib group 110 can be a grid-shaped structure composed of multiple reinforcing ribs.

[0079] The first inclined beam 13 and / or the second inclined beam 14 are provided with notches to avoid the wiper's envelope. The first rib group 19 and the second rib group 110 can be located at the notches of the first inclined beam 13 or the second inclined beam 14. The first rib group 19 and the second rib group 110 on the same inclined beam can be arranged opposite each other in the vertical direction. This can compensate for the structural weakening caused by the notches formed to avoid the wiper's envelope, ensuring the structural strength of the beam 1 and meeting the usage requirements. Secondly, it can also improve the load-bearing capacity during structural collisions and enhance vehicle safety.

[0080] In some embodiments, a third rib group 111 is provided at the angle formed by the first inclined beam 13 and the second transverse beam 12, specifically, as shown in the figure. Figure 8 As shown, the third rib group 111 can be set within the acute angle formed by the first inclined beam 13 and the second crossbeam 12, and the first inclined beam 13, the second crossbeam 12, and the third rib group 111 form a triangular structure. This improves the stiffness of the connection between the first inclined beam 13 and the second crossbeam 12.

[0081] In some embodiments, a fourth rib group 112 is provided at the angle formed by the second inclined beam 14 and the second cross beam 12, specifically, as shown in the figure. Figure 8 As shown, the fourth rib group 112 can be set within the acute angle formed by the second inclined beam 14 and the second crossbeam 12, and the second inclined beam 14, the second crossbeam 12, and the fourth rib group 112 form a triangular structure. This improves the stiffness of the connection between the second inclined beam 14 and the second crossbeam 12.

[0082] In some embodiments, such as Figure 4 and Figure 5 As shown, the cross-section of the first beam 11 is Z-shaped. Figure 4 and Figure 6As shown, the cross-section of the second crossbeam 12 is Z-shaped. This allows for improved bending resistance of the second crossbeam 12 while meeting the die-casting requirements of both the first and second crossbeams 11. The structural reinforcement of the first and second crossbeams 11 and 12 also helps to increase the rigidity of the compressor mounting point, reduce compressor excitation noise, and improve vehicle comfort.

[0083] In some embodiments, a plurality of vertical reinforcement bars 113 are evenly distributed on the top and bottom surfaces of the beam 1, and at least some of the vertical reinforcement bars 113 undulate in their extending direction. Specifically, as shown in... Figure 8 As shown, the vertical reinforcement 113 can be integrally formed on the bottom surface of the beam 1. The vertical reinforcement 113 can include ring reinforcement and linear reinforcement, wherein the ring reinforcement can extend along the inner and outer edges of the beam 1 to form a closed loop. Multiple linear reinforcements can be provided, and the corresponding linear reinforcements can be arranged along the first inclined beam 13, the second inclined beam 14, the first crossbeam 11, the second crossbeam 12, and each longitudinal beam 16. In this way, the structural strength and stiffness of the beam 1 can be enhanced.

[0084] It should be noted that the height dimension of each vertical reinforcement 113 in the vertical direction can vary along the extension direction of the vertical reinforcement 113. This variation can be determined through topology optimization design, so that the reinforced part (the higher part) of the vertical reinforcement 113 can correspond to the relatively weaker area of ​​the structure on the beam 1, making the reinforcement position of the vertical reinforcement 113 more targeted, and also helping to reduce the material consumption of the vertical reinforcement 113. While improving performance requirements, lightweight design can be achieved.

[0085] In some embodiments, such as Figures 1 to 4 As shown, any angle formed by two beams can be rounded for a smooth transition. For example, the acute angle formed by the first inclined beam 13 and the first horizontal beam 11 can be rounded with a fillet diameter of 60 mm. The acute angle formed by the second inclined beam 14 and the first horizontal beam 11 can also be rounded with a fillet diameter of 60 mm. This improves the structural strength and stiffness at the connection between the two beams and helps prevent stress concentration.

[0086] The front cabin assembly of an embodiment of the present invention is described below.

[0087] The front cabin assembly of this invention includes a mounting beam 100, which can be the mounting beam 100 described in any of the above embodiments. For example... Figure 9 As shown, the front cabin assembly includes a left shock absorber tower 200 and a right shock absorber tower 300. The left end of the first crossbeam 11 and the left end of the second crossbeam 12 are both connected to the left shock absorber tower 200, and the right end of the first crossbeam 11 and the right end of the second crossbeam 12 are both connected to the right shock absorber tower 300.

[0088] The center point (which can be considered as the axis) of the left damping tower 200 is located between the left end of the first crossbeam 11 and the left end of the second crossbeam 12, and the center point (which can be considered as the axis) of the right damping tower 300 is located between the right end of the first crossbeam 11 and the right end of the second crossbeam 12. This effectively improves the lateral (left-right) stiffness of the mounting points of the left damping tower 200 (right damping tower 300).

[0089] In some embodiments, the front compartment assembly includes a front compartment accessory, which is mounted on a corresponding mounting area 2 of the beam 1, and the front compartment accessory includes at least one of the following: a compressor, a cooling module, an expansion tank, or an air conditioning motor body. The compressor can be fixed in a first mounting area 21, the expansion tank can be fixed in a second mounting area 22, the cooling module can be fixed in a third mounting area 23, and the air conditioning motor body can be fixed in a fourth mounting area 24.

[0090] In some embodiments, such as Figure 9 As shown, the front compartment assembly also includes a front bulkhead 400, and the first connection 15 is connected and fixed to the front bulkhead 400. The front side of the front bulkhead 400 may be provided with a mounting base 401, and the rear end of the beam 1 may overlap the mounting base 401 and be connected and fixed to the mounting base 401.

[0091] The vehicle according to an embodiment of the present invention is described below.

[0092] The vehicle in this embodiment of the invention includes a front compartment assembly, which can be any of the front compartment assemblies described in the above embodiments. The vehicle can be a sedan, SUV, pickup truck, bus, or other vehicles with a front compartment assembly.

[0093] The following describes the installation beam optimization design method according to an embodiment of the present invention.

[0094] The optimized design method for the mounting beam 100 according to an embodiment of the present invention includes the following steps: S1: Create a body-in-white model with the design space of the mounting beam 100. For example, a body-in-white model containing the entire design space of the reinforcing beam can be created based on the location and arrangement space of each mounting point of the mounting beam 100. The model can specifically be a finite element model.

[0095] S2: Determine the optimal force transmission path of the mounting beam 100 within the design space through topology optimization. For example, topology optimization can be performed by 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 mounting beam 100. This will yield the optimal force transmission path of the mounting beam 100 within the design space. This optimal force transmission path should be able to meet the dynamic stiffness performance requirements while also achieving lightweight design. During topology optimization, structural dimensions and process constraints can be considered to ensure that the optimized structure meets the process requirements.

[0096] S3: Create an initial model of the mounting beam 100 based on the optimal force transmission path. For example, product design engineers can create a mounting beam 100 structure (initial model) that reflects the topology-optimized path based on the optimal force transmission path obtained through topology optimization, combined with process requirements and assembly layout requirements. It should be noted that during the initial model creation process, the thickness of the mounting beam 100 should also be optimized based on factors such as NVH dynamic stiffness, body bending and torsional stiffness, and safety collision performance, in order to obtain a lightweight structure that meets various performance requirements.

[0097] S4: Optimize the specific structure of the initial model and obtain the final model of the installation beam 100.

[0098] The optimization design of the specific structure can include the cross-sectional optimization design of the first crossbeam 11 and the second crossbeam 12. For example, the optimized cross-sectional design of the second crossbeam 12 can be a "Z" shaped cross-section, which can improve the axial and bending load-bearing capacity of the beam, significantly reduce the noise generated by the compressor excitation transmitted to the ears of the occupants, and improve the comfort of the vehicle.

[0099] The optimization design of the specific structure can also include the arrangement and structural optimization design of the reinforcing structures on beam 1. For example, "X"-shaped and grid-shaped ribs can be designed on beam 1 according to the direction of collision force transmission to improve the load-bearing capacity of the beam, increase the cross-sectional force during the collision process, and improve the safety of the vehicle.

[0100] The optimization design of the specific structure can also include optimizing the shape and thickness of the stiffeners on beam 1. For example, curved, variable-thickness stiffeners can be designed at various connections or corners. In this way, the weight of the parts can be reduced while meeting the requirements of stiffness, NVH and safety performance, thereby achieving weight reduction and cost reduction of the parts.
