[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following is for reference. Figures 1-3The front engine compartment assembly 100 and the vehicle are described according to embodiments of the present invention.

[0023] like Figures 1-3 As shown, the forward nacelle assembly 100 according to an embodiment of the present invention includes: two vibration damping towers 6, two reinforcing structures 7, and a connecting beam 10.

[0024] The two vibration damping towers 6 are along the width direction of the vehicle (i.e., the Y-direction of the vehicle). Figure 1 As shown in the Y direction, the two damping towers 6 are arranged opposite each other along the width direction of the vehicle. Two reinforcing structures 7 correspond one-to-one with the two damping towers 6 and are connected to the front end of the damping towers 6. That is, along the length direction of the vehicle (i.e., the X direction of the vehicle), the two damping towers 6 are aligned. Figure 1 (in the X direction shown) The reinforcing structure 7 is located at the front end of the corresponding vibration damping tower 6 and is connected to the front end of the corresponding vibration damping tower 6. The connection method between the reinforcing structure 7 and the vibration damping tower 6 may include, but is not limited to, welding, bolt connection, etc.

[0025] The reinforcing structure 7 is along the height direction of the vehicle (i.e., the Y-direction of the vehicle). Figure 1 The orthographic projection of the vehicle (in the Y direction shown) is a closed frame shape. Specifically, a plane is defined that is parallel to the vehicle's height direction (i.e., Figure 1 The Z-direction shown is perpendicular to the plane, meaning the normal to this plane is perpendicular to the vehicle's height direction (i.e., the Z-direction). Figure 1 Parallel to the Z direction shown, the orthographic projection of the reinforcing structure 7 onto this plane is a closed frame shape, wherein the closed frame shape can be, but is not limited to, a triangle, a quadrilateral, a pentagon, etc.

[0026] The connecting beam 10 is connected to both reinforcing structures 7. As some embodiments of this application, the connecting beam 10 is along the width direction of the vehicle (i.e., Figure 1 Extending in the Y direction (as shown), the connection method between the crossbeam 10 and the reinforcing structure 7 can include, but is not limited to, welding, bolting, etc.

[0027] Specifically, by setting up a reinforcing structure 7 and connecting the reinforcing structure 7 to the front end of the corresponding vibration damping tower 6, and by aligning the reinforcing structure 7 along the height direction of the vehicle (i.e., Figure 1The closed frame shape (as shown in the Y direction) allows for the installation of a reinforcing structure 7 with high structural rigidity and stability at the front end of the damper tower 6. In the event of a collision, the reinforcing structure 7 reliably supports the front end of the damper tower 6, reducing the risk of foreign objects intruding into the passenger compartment. Furthermore, the reinforcing structure 7 increases the structural rigidity of the damper tower 6, thereby improving the installation stability of the shock absorbers, control arms, and other structures mounted on the damper tower 6. This enhances the vehicle's handling stability and driving experience. Additionally, the two reinforcing structures 7 are connected by a connecting beam 10, forming a single integrated structure. In the event of a collision, the two damper towers 6, the two reinforcing structures 7, and the connecting beam 10 can collectively bear the collision force. This force can be transferred between the reinforcing structures 7 and the damper towers 6 on both sides via the connecting beam 10, effectively distributing the collision force, reducing stress concentration risk, and improving the vehicle's collision performance.

[0028] Therefore, by setting a reinforcing structure 7 connected to the front end of the damping tower 6, the rigidity and structural stability of the front engine compartment assembly 100 can be improved, thereby enhancing the vehicle's frontal collision performance. Furthermore, the installation stability of structures such as shock absorbers and control arms mounted on the damping tower 6 can be improved, thereby enhancing the vehicle's handling stability. In addition, by connecting the two reinforcing structures 7 through the connecting beam 10, the two damping towers 6, the two reinforcing structures 7, and the connecting beam 10 can be constructed as a whole, further enhancing the rigidity and structural stability of the front engine compartment assembly 100 and improving the vehicle's collision performance.

[0029] In some embodiments of the present invention, such as Figures 1-3 As shown, the reinforcing structure 7 includes: a first connecting beam 71, a second connecting beam 72, a third connecting beam 73, and a fourth connecting beam 74, along the length direction of the vehicle (i.e., Figure 1 (As shown in the X direction), the front end of the vibration damping tower 6 is connected to a first connecting beam 71. As some embodiments of this application, the first connecting beam 71 and the vibration damping tower 6 can be connected by, but not limited to, welding, bolting, etc. As some embodiments of this application, along the length direction of the vehicle (i.e., Figure 1 (As shown in the X direction), the parts of the first connecting beam 71 and the vibration damping tower 6 are all connected to the vibration damping tower 6. This increases the connection area between the first connecting beam 71 and the vibration damping tower 6, thereby increasing the force-bearing area and reducing the risk of concentrated collision force.

[0030] The second connecting beam 72 and the third connecting beam 73 are both connected to the first connecting beam 71 and the fourth connecting beam 74. The connection methods between the second connecting beam 72 and the first connecting beam 71 and the fourth connecting beam 74, as well as the connection methods between the third connecting beam 73 and the first connecting beam 71 and the fourth connecting beam 74, can be, but are not limited to, welding or bolting. The fourth connecting beam 74 is connected to the connecting crossbeam 10. The connection methods between the fourth connecting beam 74 and the connecting crossbeam 10 can be, but are not limited to, welding or bolting.

[0031] This arrangement allows the first connecting beam 71, the second connecting beam 72, the third connecting beam 73, and the fourth connecting beam 74 to collectively form the reinforcing structure 7, and allows the reinforcing structure 7 to extend along the height direction of the vehicle (i.e., the Y-direction of the vehicle). Figure 1 The orthographic projection of the front engine compartment assembly 100 (shown in the Y direction) is a closed frame shape, which improves the structural rigidity of the front engine compartment assembly 100. Furthermore, it can decompose the collision force from the fourth connecting beam 74 to the second connecting beam 72 and the third connecting beam 73, and then the first connecting beam 71 bears the collision force transmitted from the second connecting beam 72 and the third connecting beam 73. Finally, the shock absorber tower 6 bears the collision force from the first connecting beam 71. The force transmission path is reasonable and smooth, and it can gradually bear and reduce the collision force in multiple stages, which significantly improves the vehicle safety performance.

[0032] As some embodiments of this application, the first connecting beam 71, the second connecting beam 72, the third connecting beam 73, and the fourth connecting beam 74 can all be constructed as hollow tube beams, and the cross-section of any one of the first connecting beam 71, the second connecting beam 72, the third connecting beam 73, and the fourth connecting beam 74 can be rectangular or circular.

[0033] In some embodiments of the present invention, such as Figures 1-3 As shown, the first connecting beam 71 is along the width direction of the vehicle (i.e., Figure 1 Extending in the Y direction (as shown), this increases the connection area between the first connecting beam 71 and the vibration damping tower 6, thereby increasing the stress area and reducing the risk of concentrated collision force.

[0034] One end of the second connecting beam 72 and one end of the third connecting beam 73 are respectively connected to both ends of the first connecting beam 71. The other ends of the second connecting beam 72 and the third connecting beam 73 are both connected to the fourth connecting beam 74. The fourth connecting beam 74 is along the height direction of the vehicle (i.e., Figure 1 (as shown in the Z direction). This arrangement allows the reinforcing structure 7 to extend along the vehicle's height direction (i.e., the vehicle's Y direction, i.e., the Z direction). Figure 1The orthographic projection of the Y-direction shown is triangular, which can significantly improve the stiffness of the reinforcing structure 7. As some embodiments of this application, the upper end of the fourth connecting beam 74 is connected to the connecting crossbeam 10. This arrangement allows the connecting crossbeam 10 to be supported by two reinforcing structures 7, which is beneficial for improving the stiffness of the front engine compartment assembly 100 along the height direction of the vehicle (i.e., Figure 1 The ability to withstand impact force (as shown in the Z direction).

[0035] In some embodiments of the present invention, such as Figures 1-3 As shown, the other end of the second connecting beam 72 and the other end of the third connecting member 77 are spaced apart along the height direction of the vehicle. That is, along the height direction of the vehicle (i.e., Figure 1 (As shown in the Z direction), the height of the end where the second connecting beam 72 connects to the fourth connecting beam 74 is higher than the height of the end where the third connecting beam 73 connects to the fourth connecting beam 74, or the height of the end where the second connecting beam 72 connects to the fourth connecting beam 74 is lower than the height of the end where the third connecting beam 73 connects to the fourth connecting beam 74. This arrangement can support the fourth connecting beam 74 from multiple locations, reducing the risk of bending under stress and improving the load-bearing performance of the fourth connecting beam 74.

[0036] In some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle's front engine compartment assembly 100 also includes: a first longitudinal beam 31, the number of which is the same as and corresponds one-to-one with the vibration damper towers 6. The first longitudinal beam 31 is connected to the corresponding vibration damper tower 6 on the inner side along the width direction of the vehicle, that is, the first longitudinal beam 31 is located at the end of the corresponding vibration damper tower 6 facing the other vibration damper tower 6 and is connected to the end of the corresponding vibration damper tower 6 facing the other vibration damper tower 6. As some embodiments of this application, along the width direction of the vehicle (i.e. Figure 1 (As shown in the Y direction), the parts of the first longitudinal beam 31 corresponding to the vibration damping tower 6 are all connected to the vibration damping tower 6. This increases the connection area between the first longitudinal beam 31 and the vibration damping tower 6, thereby increasing the stress-bearing area and reducing the risk of concentrated collision force. The first longitudinal beam 31 and the vibration damping tower 6 can be connected by, but is not limited to, welding, bolting, etc.

[0037] The first longitudinal beam 31 is connected to both the corresponding first connecting beam 71 and the corresponding second connecting beam 72. In some embodiments of this application, the front end of the first longitudinal beam 31 is connected to the end of the corresponding first connecting beam 71 near another first connecting beam 71, and the rear end of the corresponding second connecting beam 72. Furthermore, the end of the first connecting beam 71 near another first connecting beam 71 is connected to the rear end of the corresponding second connecting beam 72. This arrangement allows the first longitudinal beam 31 to bear the force of the first connecting beam 71, the force of the second connecting beam 72, and transmits it rearward. It also allows the first longitudinal beam 31 and the vibration damping tower 6 to be constructed as a single unit and jointly bear the collision force, which is beneficial for improving the vehicle's collision performance.

[0038] In some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle's front engine compartment assembly 100 also includes: a second longitudinal beam 32 and a third longitudinal beam 75. The second longitudinal beam 32, the first longitudinal beam 31, and the third longitudinal beam 75 are of the same number and correspond one-to-one, running along the height direction of the vehicle (i.e., Figure 1 (As shown in the Z direction), the orthographic projection of the second longitudinal beam 32 and the orthographic projection of the corresponding first longitudinal beam 31 have an overlapping area, and the third longitudinal beam 75 is connected to the front end of the corresponding second longitudinal beam 32.

[0039] Among them, the second longitudinal beam 32 is along the length direction of the vehicle (i.e. Figure 1 Extending in the X direction (as shown), as in some embodiments of this application, the second longitudinal beam 32 is constructed as a hollow tubular structure with a rectangular cross-section along a direction perpendicular to the extension direction of the second longitudinal beam 32. As in some embodiments of this application, the second longitudinal beam 32 is constructed as a hollow tubular structure with a circular cross-section along a direction perpendicular to the extension direction of the second longitudinal beam 32.

[0040] Along the height direction of the vehicle (i.e., the Z-direction of the vehicle), Figure 1 (As shown in the Z direction), the orthographic projection of the second longitudinal beam 32 and the orthographic projection of the first longitudinal beam 31 have an overlapping area. When a frontal collision occurs, the second longitudinal beam 32 and the first longitudinal beam 31 form two force transmission paths, which helps to reduce the risk of stress concentration on the second longitudinal beam 32 or the first longitudinal beam 31. Furthermore, the collision force can be decomposed through multiple force transmission paths, thereby reducing the risk of components in the front engine compartment assembly 100 intruding into the passenger compartment due to the breakage of the second longitudinal beam 32 or the first longitudinal beam 31, thus further improving the rigidity and structural stability of the front engine compartment assembly 100.

[0041] The third longitudinal beam 75 is connected to the front end of the corresponding second longitudinal beam 32. In some embodiments of this application, the rear end of the third longitudinal beam 75 is connected to the front end of the corresponding second longitudinal beam 32. The connection methods between the third longitudinal beam 75 and the second longitudinal beam 32 include, but are not limited to, welding and bolting. By connecting the third longitudinal beam 75 to the front end of the corresponding second longitudinal beam 32, in the event of a frontal collision, the third longitudinal beam 75 and the second longitudinal beam 32 can combine to form a longer force transmission path, thereby extending the energy absorption stroke, smoothly transmitting the collision force rearward, and improving the overall vehicle collision safety.

[0042] In some embodiments of this application, the second longitudinal beam 32 is indirectly connected to the front bulkhead 5. In some embodiments of this application, the second longitudinal beam 32 is directly connected to the front bulkhead 5. In some embodiments of this application, the second longitudinal beam 32 is welded to the front bulkhead 5. In some embodiments of this application, the second longitudinal beam 32 is bolted to the front bulkhead 5. In some embodiments of this application, along the length of the vehicle, the rear end of the second longitudinal beam 32 is welded to the front bulkhead 5.

[0043] As some embodiments of this application, the first longitudinal beam 31 and the second longitudinal beam 32 are directly opposite each other. This arrangement is reasonable and can reduce the Y-direction space occupied by the first longitudinal beam 31 and the second longitudinal beam 32. Moreover, the overall structure formed by the first longitudinal beam 31, the second longitudinal beam 32 and the second reinforcing beam 36 can have excellent Z-direction bearing capacity, thereby improving the impact resistance of the front engine compartment assembly 100 along the height direction of the vehicle.

[0044] In some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle's front engine compartment assembly 100 also includes at least one first reinforcing beam 76, which is connected between the second connecting beam 72 and the third longitudinal beam 75.

[0045] In some embodiments of this application, there is one first reinforcing beam 76. In some embodiments of this application, there are two first reinforcing beams 76.

[0046] In some embodiments of this application, the first reinforcing beam 76 is welded between the second connecting beam 72 and the third longitudinal beam 75. In some embodiments of this application, the first reinforcing beam 76 is bolted between the second connecting beam 72 and the third longitudinal beam 75. This arrangement effectively improves the relative stability of the second connecting beam 72 and the third longitudinal beam 75, reduces the risk of bending of the second connecting beam 72 and the third longitudinal beam 75, and thus further improves the safety of vehicle collisions.

[0047] In some embodiments of the present invention, such as Figures 1-3 As shown, the vehicle's front engine compartment assembly 100 also includes at least one second reinforcing beam 36, which connects the first longitudinal beam 31 and the second longitudinal beam 32.

[0048] In some embodiments of this application, there is one second reinforcing beam 36. In some embodiments of this application, there are two second reinforcing beams 36. In some embodiments of this application, the second reinforcing beam 36 is welded between the first longitudinal beam 31 and the second longitudinal beam 32. In some embodiments of this application, the second reinforcing beam 36 is bolted between the first longitudinal beam 31 and the second longitudinal beam 32. This arrangement effectively improves the relative stability of the first longitudinal beam 31 and the second longitudinal beam 32, reduces the risk of bending of the first longitudinal beam 31 and the second longitudinal beam 32, and thus further improves the safety of vehicle collisions.

[0049] As some embodiments of this application, a plurality of second reinforcing beams 36 are arranged along the length of the vehicle, and the extensions of at least one pair of adjacent second reinforcing beams 36 intersect to form a triangle with a portion of the first longitudinal beam 31 or a portion of the second longitudinal beam 32.

[0050] For example, there are two second reinforcing beams 36, which are arranged along the length of the vehicle and the extensions of the two second reinforcing beams 36 intersect to form a triangle with a portion of the first longitudinal beam 31 or a portion of the second longitudinal beam 32. Since triangles have better stability, this arrangement can improve the relative stability between the first longitudinal beam 31, the second longitudinal beam 32 and the two second reinforcing beams 36, further improving the rigidity and structural stability of the front engine compartment assembly 100, and further improving the vehicle's collision safety.

[0051] In some embodiments of the present invention, such as Figure 2 As shown, one end of the second reinforcing beam 36 is connected to the first longitudinal beam 31, and the other end is connected to the second longitudinal beam 32 and the front bulkhead 5.

[0052] In some embodiments of this application, one end of the second reinforcing beam 36 is welded to the lower side of the first longitudinal beam 31 along the vehicle height direction. In some embodiments of this application, the connection between the second reinforcing beam 36 and the first longitudinal beam 31 is located in the middle of the first longitudinal beam 31. In some embodiments of this application, the other end of the second reinforcing beam 36 is welded to both the second longitudinal beam 32 and the front bulkhead 5. This arrangement allows the collision force to be transferred among the first longitudinal beam 31, the second longitudinal beam 32, the second reinforcing beam 36, and the front bulkhead 5, which helps to disperse the collision force during a vehicle collision, reduces the risk of stress concentration, and thus improves the safety of occupants.

[0053] In some embodiments of the present invention, such as Figure 1 As shown, the distance between the two third longitudinal beams 75 gradually decreases from the end of the third longitudinal beam 75 away from the second longitudinal beam 32 to the end closer to the second longitudinal beam 32.

[0054] That is to say, along the length of the vehicle (i.e. Figure 1 As shown in the X direction, the spacing between the two third longitudinal beams 75 gradually decreases from the front to the rear of the vehicle. In other words, along the length of the vehicle (i.e., the distance between the beams 75 and the distance between the beams 75 gradually decreases). Figure 1 As shown in the X direction, the third longitudinal beam 75 gradually slopes inwards from the front to the rear of the vehicle. This arrangement allows the third longitudinal beam 75 to avoid the wheel envelope, providing more space for wheel steering, adapting to vehicles with larger steering angles, and enabling the third longitudinal beam 75 to effectively transmit frontal and side impact forces, thus improving the vehicle's collision performance.

[0055] In some embodiments of the present invention, such as Figure 3 As shown, the vehicle's front engine compartment assembly 100 also includes: connectors 77, which are the same number as and correspond one-to-one with the fourth connecting beams 74, along the vehicle's height direction (i.e., Figure 1(As shown in the Z direction), the connector 77 is connected to the lower end of the corresponding fourth connecting beam 74, and the third longitudinal beam 75 is connected to the corresponding connector 77.

[0056] The connection methods between the connector 77 and the fourth connecting beam 74, and between the connector 77 and the third longitudinal beam 75, can include, but are not limited to, welding and bolting. By connecting the connector 77 to the lower end of the corresponding fourth connecting beam 74, the connector 77 can support the corresponding fourth connecting beam 74. The upper end of the fourth connecting beam 74 is connected to the connecting crossbeam 10. Thus, the overall structure formed by the connector 77 and the fourth connecting beam 74 supports the connecting crossbeam 10, which helps to improve the front engine compartment assembly 100 along the vehicle's height direction (i.e.,...). Figure 1 The third longitudinal beam 75 is connected to the corresponding connecting piece 77, which helps to form a frame structure with the third longitudinal beam 75, connecting piece 77, second connecting beam 72, and second reinforcing beam 36, significantly improving the structural rigidity of the front engine compartment assembly 100.

[0057] As some embodiments of this application, the front engine compartment assembly 100 proposed in this application can be constructed as a modified vehicle's front engine compartment assembly 100. A modified vehicle can be understood as a vehicle model formed by cutting some parts of an existing vehicle and connecting new structures to the remaining parts to adapt to new vehicle components (e.g., cutting some parts of the original vehicle's body and connecting new structures to the remaining parts to adapt the body to corner modules). The connector 77 can be the front section of the original vehicle's longitudinal beam. The connector 77 can serve as a connecting assembly, connecting the fourth connecting beam 74, the third longitudinal beam 75, the upper side beam 2, and other vehicle components (including but not limited to the front bumper, anti-collision beam, etc.). In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the front engine compartment assembly 100 of the vehicle also includes: a fifth connecting beam 78 and an upper side beam 2. The fifth connecting beam 78, the upper side beam 2, and the vibration damping tower 6 are the same in number and correspond one-to-one. The fifth connecting beam 78 connects the corresponding vibration damping tower 6 and the corresponding upper side beam 2.

[0058] As some embodiments of this application, the fifth connecting beam 78 is directly connected to the vibration damping tower 6, and the fifth connecting beam 78 is connected to the front end of the vibration damping tower 6. The connection method between the fifth connecting beam 78 and the vibration damping tower 6 may include, but is not limited to, welding connection, bolt connection, etc. The fifth connecting beam 78 may be directly connected to the corresponding upper beam 2, or the fifth connecting beam 78 may be connected to the corresponding upper beam 2 through a bracket.

[0059] By connecting the fifth connecting beam 78 to the damping tower 6 and the upper beam 2, the force transmission between the damping tower 6 and the upper beam 2 can be smooth, thereby dispersing the collision force and improving the vehicle's collision performance.

[0060] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the upper beam 2 includes: a first side beam segment 211 and a second side beam segment 213. The first side beam segment 211 and the second side beam segment 213 are connected. Along the width direction of the vehicle, a portion of the second side beam segment 213 is located on the side of the first side beam segment 211 that is close to the other upper beam 2. The fifth connecting beam 78 is connected to both the first side beam segment 211 and the second side beam segment 213.

[0061] As some embodiments of this application, the connection method between the first side beam segment 211 and the second side beam segment 213 may include, but is not limited to, welding connection, bolt connection, etc. Along the width direction of the vehicle, a portion of the second side beam segment 213 is located on the side of the first side beam segment 211 closer to the other upper side beam 2, that is, a portion of the second side beam segment 213 is located inside the first side beam segment 211. Along the length direction of the vehicle, a portion of the second side beam segment 213 is further forward than the first side beam segment 211, that is, along the length direction of the vehicle, a portion of the structure of the second side beam segment 213 is located in front of the first side beam segment 211. It can be understood that both the second side beam segment 213 and the first side beam segment 211 can extend obliquely along the length direction of the vehicle, that is, a portion of the structure of the second side beam segment 213 is not located directly in front of the first side beam segment 211, but rather obliquely in front of the first side beam segment 211.

[0062] The fifth connecting beam 78 is connected to both the first side beam segment 211 and the second side beam segment 213. This arrangement improves the connection stability between the fifth connecting beam 78 and the upper side beam 2. In some embodiments of this application, the fifth connecting beam 78 can be connected to the corresponding upper side beam 2 via adapter brackets. Multiple adapter brackets are used; the fifth connecting beam 78 is connected to the first side beam segment 211 via one adapter bracket, and to the second side beam segment 213 via another adapter bracket. This arrangement raises the fifth connecting beam 78, avoiding the problem of the fifth connecting beam 78 being blocked by the second side beam segment 213 and unable to connect to the first side beam segment 211, thus ensuring that the fifth connecting beam 78 is connected to both the first side beam segment 211 and the second side beam segment 213.

[0063] As some embodiments of this application, the second side beam segment 213 can be the front section of the side beam on the wheel arch of the original vehicle, which is modified to serve as the second side beam segment 213 of this application.

[0064] As some embodiments of this application, the second side beam segment 213 is located above and connected to the connector 77. Further, the second side beam segment 213 is located above the connector 77 and the front end of the second side beam segment 213 is connected to the connector 77. This arrangement can support the second side beam segment 213 through the connector 77, thereby improving the installation stability of the upper side beam 2.

[0065] In some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the connecting beam 10 includes: a first beam body 101 and a first connecting sub-beam 102. Both ends of the first beam body 101 are connected to the first connecting sub-beam 102. Both first connecting sub-beams 102 are along the height direction of the vehicle (i.e.,...). Figure 1 (As shown in the Z direction) extends and connects to the two upper beams 2 respectively.

[0066] Both ends of the first beam body 101 are connected to the first connecting sub-beams 102. As some embodiments of this application, the connection method between the first beam body 101 and the first connecting sub-beams 102 at both ends can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc. Alternatively, the first beam body 101 and the first connecting sub-beams 102 at both ends can be integrally formed.

[0067] As some embodiments of this application, the first connecting sub-beam 102 can be along the height direction of the vehicle (i.e., Figure 1 Extending vertically in the Z direction (as shown), specifically, both first connecting sub-beams 102 are perpendicular to the first beam body 101. It should be noted that the "perpendicular" mentioned above refers to industrially achievable perpendicularity, not absolute perpendicularity in a mathematical sense. Therefore, an angle between the first connecting sub-beam 102 and the first beam body 101 within the range of 88° to 92° is considered perpendicular. Thus, the connecting beam 10 can be constructed as a U-shaped structure, meaning the first beam body 101 and the first connecting sub-beams 102 at both ends together form a U-shaped structure.

[0068] As some embodiments of this application, both first connecting sub-beams 102 are along the height direction of the vehicle (i.e., the Z-direction of the vehicle). Figure 1 As shown in the Z direction, it extends obliquely and connects to the two upper beams 2 respectively. As some embodiments of this application, along the height direction of the vehicle (i.e., the Z direction of the vehicle), Figure 1 (As shown in the Z direction), the included angles between the two first connecting sub-beams 102 and the first beam body 101 are both obtuse angles.

[0069] Two first connecting sub-beams 102 are respectively connected to two upper beams 2. As some embodiments of this application, the connection method between the first connecting sub-beams 102 and the corresponding upper beams 2 can be, but is not limited to, welding connection, snap-fit ​​connection, bolt connection, etc.

[0070] As some embodiments of this application, one end of the first connecting sub-beam 102 is connected to the upper beam 2, and the other end of the first connecting sub-beam 102 is connected to the end of the first beam body 101.

[0071] As a specific embodiment of this application, the first connecting sub-beam 102 is bolted to the corresponding upper beam 2. Specifically, the first connecting sub-beam 102 has a first connecting flange at one end near the corresponding upper beam 2, and the first connecting flange 103 has a first connecting hole. The upper beam 2 has a first mounting hole corresponding to the first connecting hole. The bolt passes through the first connecting hole and the first mounting hole in sequence and cooperates with the nut so that the first connecting sub-beam 102 is connected to the corresponding upper beam 2.

[0072] This configuration raises the first beam body 101 to avoid obstructing the piping and other assembly parts inside the front engine compartment assembly 100, which helps improve the space utilization of the front engine compartment assembly 100. Furthermore, it facilitates the disassembly and assembly of the piping and other assembly parts inside the front engine compartment assembly 100, thereby improving the ease of assembly and maintenance of the front engine compartment assembly 100.

[0073] According to an embodiment of the present invention, the vehicle includes the front engine compartment assembly 100 of the above embodiment. By providing a reinforcing structure 7 connected to the front end of the damping tower 6, the rigidity and structural stability of the front engine compartment assembly 100 can be improved, thereby enhancing the vehicle's frontal collision performance. Furthermore, the installation stability of structures such as shock absorbers and swing arms mounted on the damping tower 6 can be improved, thereby enhancing the vehicle's handling stability. In addition, by connecting the two reinforcing structures 7 through the connecting beam 10, the two damping towers 6, the two reinforcing structures 7, and the connecting beam 10 can be constructed as a whole, further enhancing the rigidity and structural stability of the front engine compartment assembly 100 and improving the vehicle's collision performance.
