[0030] The embodiments of this utility model 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 this utility model, and should not be construed as limiting this utility model.

[0031] The following is for reference. Figures 1-5 This invention describes a front crossbeam 100 for mounting a battery pack in a vehicle, and a vehicle, according to an embodiment of the present invention. Figures 2-4 These are all bottom views, taken from the bottom of the vehicle and looking upwards.

[0032] like Figures 1-5As shown, according to an embodiment of the present invention, a front crossbeam 100 for battery pack installation in a vehicle is provided. The vehicle has a longitudinal beam 200 in the engine compartment, a sill beam 300, and a center channel 400. The front crossbeam 100 for battery pack installation includes a crossbeam body 10 and two connecting portions 20. The crossbeam body 10 extends along the width direction of the vehicle. The two connecting portions 20 are respectively connected to both ends of the crossbeam body 10. The two connecting portions 20 are respectively used to connect with the corresponding sill beam 300 and the corresponding longitudinal beam 200 in the engine compartment. The crossbeam body 10 is used to connect with the longitudinal beam 200 in the engine compartment, the center channel 400, and the battery pack 500.

[0033] In this embodiment, the two connecting parts 20 are respectively connected to both ends of the crossbeam body 10. In some embodiments of this application, the connecting parts 20 and the crossbeam body 10 can be connected by bolts or by welding. However, this utility model is not limited to this. The connecting parts 20 and the crossbeam body 10 can also be connected in other ways, as long as the two connecting parts 20 are respectively connected to both ends of the crossbeam body 10.

[0034] The two connecting parts 20 are respectively used to connect with the corresponding sill beam 300 and the corresponding cabin longitudinal beam 200. In some embodiments of this application, the corresponding connecting part 20 and the corresponding sill beam 300 can be connected by bolts, or the corresponding connecting part 20 and the corresponding sill beam 300 can be connected by welding. However, this utility model is not limited to this. The corresponding connecting part 20 and the corresponding sill beam 300 can also be connected by other means, as long as the corresponding connecting part 20 and the corresponding sill beam 300 are connected.

[0035] The corresponding connecting part 20 and the corresponding cabin longitudinal beam 200 can be connected by bolts or by welding. However, this utility model is not limited to this. The corresponding connecting part 20 and the corresponding cabin longitudinal beam 200 can also be connected by other means, as long as the corresponding connecting part 20 and the corresponding cabin longitudinal beam 200 are connected.

[0036] The crossbeam body 10 is used to connect with the cabin longitudinal beam 200, the central channel 400, and the battery pack 500. In some embodiments of this application, the crossbeam body 10 can be bolted to the cabin longitudinal beam 200, the central channel 400, and the battery pack 500, or welded to the cabin longitudinal beam 200, the central channel 400, and the battery pack 500. However, this utility model is not limited to this. The crossbeam body 10 can also be connected to the cabin longitudinal beam 200, the central channel 400, and the battery pack 500 in other ways, as long as the crossbeam body 10 is used to connect with the cabin longitudinal beam 200, the central channel 400, and the battery pack 500.

[0037] Two connecting parts 20 are used to connect with the corresponding sill beam 300 and the corresponding engine compartment longitudinal beam 200 respectively. The crossbeam body 10 is used to connect with the engine compartment longitudinal beam 200, the central channel 400 and the battery pack 500. When the vehicle is hit by a collision, the collision force can be dispersed from the crossbeam 100 in front of the battery pack to the sill beam 300 and the central channel 400, avoiding the collision energy from acting directly on the battery pack 500. It can also reduce the risk of the front engine compartment of the vehicle squeezing the battery pack 500, thereby protecting the battery pack 500 from damage. It also reduces the impact and vibration of the battery pack 500 during driving, improving the safety and reliability of the battery pack 500 and the vehicle.

[0038] Specifically, such as Figure 3 As shown, two connecting parts 20 are used to connect with the corresponding sill beam 300 and the corresponding engine compartment longitudinal beam 200 respectively. The crossbeam body 10 is used to connect with the engine compartment longitudinal beam 200, the central channel 400 and the battery pack 500. It can disperse the collision force received by the front of the vehicle to multiple force transmission paths. In particular, it can disperse the force on the shorter engine compartment longitudinal beam 200 to the central channel 400 and the corresponding sill beam 300, which greatly reduces the force on the shorter engine compartment longitudinal beam 200 acting directly on the battery pack 500. This can reduce the risk of the front engine compartment of the vehicle squeezing the battery pack 500, thereby protecting the battery pack 500 from damage.

[0039] Furthermore, the connection between the crossbeam body 10 and the battery pack 500 provides additional support and protection for the battery pack 500, allowing it to be more securely installed in the vehicle and improving its stability. The front crossbeam 100, together with the engine compartment longitudinal beam 200, sill beam 300, and center tunnel 400, forms a stable support structure, strengthening the overall vehicle structure. This not only reduces the intrusion and deformation of the front of the battery pack 500 during a collision, preventing fire and explosion, but also effectively reduces deformation of the front engine compartment during a collision, providing greater survival space for occupants. In addition, the front crossbeam 100 has a simple structure and is lightweight, contributing to improved vehicle weight reduction and fuel economy.

[0040] According to an embodiment of the present invention, a front crossbeam 100 for battery pack mounting in a vehicle extends along the width direction of the vehicle via a crossbeam body 10. Two connecting parts 20 are respectively connected to both ends of the crossbeam body 10. The two connecting parts 20 are respectively used to connect with the corresponding sill beam 300 and the corresponding engine compartment longitudinal beam 200. The crossbeam body 10 is used to connect with the engine compartment longitudinal beam 200, the center channel 400 and the battery pack 500. When the vehicle is involved in a collision, the collision force can be dispersed from the front crossbeam 100 for battery pack mounting to the sill beam 300 and the center channel 400, reducing the risk of the front engine compartment of the vehicle squeezing the battery pack 500. It can also protect the battery pack 500, improving the safety and reliability of the battery pack 500 and the vehicle. Furthermore, the front crossbeam 100 for battery pack mounting has a simple structure and is lightweight, which is beneficial to improving the vehicle's lightweight performance and economy.

[0041] According to some embodiments of the present invention, such as Figure 1 As shown, at least one connecting portion 20 may be configured as an arc to form a clearance space on the upper side of the corresponding connecting portion 20, the clearance space being used to avoid vehicle components.

[0042] In this embodiment, at least one connecting portion 20 is constructed in an arc shape. In some embodiments of this application, one of the two connecting portions 20 may be constructed in an arc shape, or both connecting portions 20 may be constructed in an arc shape, as long as at least one connecting portion 20 is constructed in an arc shape. The arc shape of the corresponding connecting portion 20 may protrude downwards towards the corresponding connecting portion 20 to form a clearance space on the upper side of the corresponding connecting portion 20. The clearance space is used to avoid vehicle components, such as connecting pipelines, pipeline channels, etc. The existence of the clearance space reduces interference between components, making the interior layout of the vehicle more reasonable and improving the space utilization of the vehicle.

[0043] The clearance space not only provides a place for the components, but also protects them to a certain extent. The design of the arc-shaped connection part 20 can reduce the impact of external impacts on the components and improve the overall safety and reliability of the vehicle.

[0044] It can be noted that, along the height direction of the vehicle, the upper side of the corresponding connecting part 20 is the side of the corresponding connecting part 20 facing the roof.

[0045] According to some embodiments of the present invention, such as Figure 1As shown, the arc-shaped connecting part 20 is detachably connected to the crossbeam body 10. In some embodiments of this application, the arc-shaped connecting part 20 and the crossbeam body 10 can be connected by bolts, or by snap-fit ​​connection. However, this utility model is not limited to these methods. The arc-shaped connecting part 20 and the crossbeam body 10 can also be connected in other ways, as long as the arc-shaped connecting part 20 and the crossbeam body 10 are detachably connected. This design allows the components corresponding to the arc-shaped connecting part 20 to be installed first, and then the arc-shaped connecting part 20 and the crossbeam body 10 can be connected. This improves the ease of installation of the components corresponding to the arc-shaped connecting part 20 and simplifies the installation difficulty of internal vehicle components.

[0046] Furthermore, when the crossbeam body 10, the arc-shaped connecting part 20, or the parts in the clearance space malfunction or are damaged, the detachable connection method makes maintenance and replacement work more convenient. Simply remove the damaged parts, replace them with new parts, and reconnect them, which greatly reduces maintenance costs and time.

[0047] According to some embodiments of the present invention, such as Figure 1 As shown, the arc-shaped connecting part 20 may include: a connecting part body 211 and a first flange 212. The connecting part body 211 is arc-shaped and connected to the crossbeam body 10. The edge of the connecting part body 211 is connected to the first flange 212, and the first flange 212 is bent towards the lower side of the corresponding connecting part 20.

[0048] Among them, such as Figure 1 As shown in the example of this application, the two connecting parts 20 can be a first connecting part 21 and a second connecting part 22, respectively. The first connecting part 21 is an arc-shaped connecting part 20. The arc-shaped connecting part 20 includes a connecting part body 211 and a first flange 212. The connecting part body 211 is arc-shaped and connected to the crossbeam body 10. The edge of the connecting part body 211 is connected to the first flange 212. In some embodiments of this application, the connecting part body 211 and the first flange 212 can be fixedly connected by welding, or the connecting part body 211 and the first flange 212 can be integrally formed. However, this utility model is not limited to this. The connecting part body 211 and the first flange 212 can also be connected in other ways, as long as the edge of the connecting part body 211 is connected to the first flange 212.

[0049] Along the height of the vehicle, the lower side of the connecting part 20 is the side of the connecting part 20 facing the ground. The first flange 212 bends towards the lower side of the corresponding connecting part 20. This can reduce the occupation of the clearance space above the first connecting part 21 by the first flange 212 while improving the strength of the first connecting part 21. This avoids the waste of space or layout difficulties caused by the protrusion of the first flange 212. It can also avoid the risk of the first flange 212 scraping or cutting the components (such as connecting pipelines, pipeline channels, etc.) in the clearance space due to vibration and friction during vehicle operation. This protects the connecting pipelines, pipeline channels, and other components from damage and helps to improve the safety and reliability of the vehicle.

[0050] According to some embodiments of the present invention, such as Figure 1 As shown, the connecting body 211 may have a first mounting hole 213 and a second mounting hole 214. The first mounting hole 213 and the second mounting hole 214 are arranged along the extension direction of the front crossbeam 100 of the battery pack installation. The second mounting hole 214 is located on the side of the first mounting hole 213 away from the crossbeam body 10. The first mounting hole 213 is used to assemble with the crossbeam body 10, and the second mounting hole 214 is used to assemble with the corresponding sill beam 300.

[0051] The pre-set first assembly hole 213 and second assembly hole 214 simplify the assembly process of the connecting part body 211 with the crossbeam body 10 and the corresponding sill beam 300, reduce the adjustment and correction work during assembly, thereby improving assembly efficiency, and also helping to reduce the assembly error rate and improve assembly quality.

[0052] Furthermore, this configuration allows the connecting part 211 to be detachably connected to the crossbeam 10 and the corresponding sill beam 300. This enables the connection between the arc-shaped connecting part 20 and the crossbeam 10 to be completed after the components corresponding to the arc-shaped connecting part 20 are installed. This further improves the ease of installation of the components corresponding to the arc-shaped connecting part 20 and simplifies the installation difficulty of the internal components of the vehicle.

[0053] According to some embodiments of the present invention, such as Figure 1 As shown, the connecting body 211 may be formed with a reinforcing structure 215, which is located between the first mounting hole 213 and the second mounting hole 214 along the extension direction of the front crossbeam 100 of the battery pack installation.

[0054] The connecting body 211 can be reinforced with a strengthening structure 215, which can be constructed as a reinforcing rib, a reinforcing boss, or other similar structure. This significantly improves the structural strength of the connecting body 211. During vehicle operation, the strengthening structure 215 effectively resists forces and vibrations from different directions, ensuring the stability and durability of the connecting part 20. Along the extension direction of the front crossbeam 100 for battery pack installation, the strengthening structure 215 is located between the first mounting hole 213 and the second mounting hole 214. This further reinforces the surrounding area of ​​the mounting points at the first mounting hole 213 and the second mounting hole 214, reducing the risk of deformation or damage caused by forces on the first mounting hole 213 and the second mounting hole 214, thereby improving the safety and stability of the entire vehicle.

[0055] According to some embodiments of the present invention, at least one connecting part 20 is fixedly connected to the crossbeam body 10. In some embodiments of the present application, one of the two connecting parts 20 may be fixedly connected to the crossbeam body 10, or both connecting parts 20 may be fixedly connected to the crossbeam body 10. However, the present invention is not limited to this. As long as at least one connecting part 20 is fixedly connected to the crossbeam body 10, it is acceptable.

[0056] As an example of this application, the two connecting parts 20 can be a first connecting part 21 and a second connecting part 22, respectively. The first connecting part 21 is detachably connected to the crossbeam body 10, and the second connecting part 22 is fixedly connected to the crossbeam body 10. The second connecting part 22 is also fixedly connected to the engine compartment longitudinal beam 200, so that the second connecting part 22, the crossbeam body 10, and the engine compartment longitudinal beam 200 form a stable overall structure. This can enhance the connection strength between the front crossbeam 100 and the engine compartment longitudinal beam 200 before the battery pack is installed, thereby improving the overall stability of the vehicle. Moreover, the fixed connection method makes the force transmission between the second connecting part 22 and the crossbeam body 10 more direct and efficient, which is conducive to the effective dispersion of vehicle collision energy, thereby reducing the risk of the front engine compartment of the vehicle squeezing the battery pack 500 and protecting the battery pack 500 from damage.

[0057] Furthermore, the second connecting portion 22 may have a second flange 221. The second flange 221 may be located at the end of the second connecting portion 22 away from the crossbeam body 10. The second connecting portion 22 may be welded to the cabin longitudinal beam 200 through the second flange 221 to increase the connection area between the second connecting portion 22 and the cabin longitudinal beam 200, thereby improving the connection strength between the second connecting portion 22 and the cabin longitudinal beam 200.

[0058] According to some embodiments of the present invention, such as Figure 1 As shown, the crossbeam body 10 can form a protruding section 11 that protrudes upwards from the crossbeam body 10, and the protruding section 11 is used to connect with the central channel 400.

[0059] Along the height direction of the vehicle, the side of the crossbeam body 10 facing the roof is the upper side of the crossbeam body 10. The crossbeam body 10 can form a protruding section 11 that protrudes upwards, so that the connection surface between the protruding section 11 and the central channel 400 is more flush, so that the protruding section 11 and the central channel 400 can be tightly connected. There is no need to set an additional connecting part between the crossbeam body 10 and the central channel 400, which can reduce the number of vehicle parts and is beneficial to the vehicle's lightweight performance and economy.

[0060] The close connection between the protruding section 11 and the central channel 400 enhances the rigidity of the entire vehicle structure. Through the mutual support of the protruding section 11 and the central channel 400, a more stable overall structure is formed, which can effectively resist the action of external forces and reduce body deformation and torsion.

[0061] Furthermore, a third flange 12 can be formed on the edge side of the beam body 10. The beam body 10 can be welded to the central channel 400 and the cabin longitudinal beam 200 through the third flange 12. The presence of the third flange 12 is also conducive to the dispersion of forces on the beam body 10, avoiding stress concentration, thereby improving the stability and reliability of the beam body 10.

[0062] According to some embodiments of this utility model, the front floor of the vehicle has a foot pedal area. Along the height direction of the vehicle, the front crossbeam 100 for mounting the battery pack is adapted to be mounted under the front floor and corresponds to the foot pedal area. This can significantly enhance the structural strength of the front floor of the vehicle. The foot pedal area is a region inside the vehicle that bears a large load. By increasing the support of the front crossbeam 100 for mounting the battery pack, deformation of the front floor of the vehicle can be effectively prevented, improving the durability and safety of the vehicle. Furthermore, placing the front crossbeam 100 for mounting the battery pack under the front floor and corresponding to the foot pedal area helps to optimize the weight distribution of the vehicle, making the center of gravity of the vehicle lower and improving the stability and handling performance of the vehicle.

[0063] Furthermore, such as Figure 1 and Figure 5 As shown, the crossbeam body 10 can also form multiple mounting points 40 for fixed connection between the crossbeam body 10 and the battery pack 500, thereby providing additional support and protection for the battery pack 500, making the battery pack 500 more securely installed in the vehicle, which helps to improve the stability of the battery pack 500. The crossbeam 100 before battery pack installation can also form multiple weight-reducing holes 30 and reinforcing structures 215, which can both improve the structural strength of the crossbeam 100 before battery pack installation and reduce the weight of the crossbeam 100 before battery pack installation.

[0064] The vehicle according to this utility model embodiment includes the battery pack mounting front crossbeam 100 of the above embodiment. The crossbeam body 10 extends along the width direction of the vehicle, and two connecting parts 20 are respectively connected to both ends of the crossbeam body 10. The two connecting parts 20 are respectively used to connect with the corresponding sill beam 300 and the corresponding engine compartment longitudinal beam 200. The crossbeam body 10 is used to connect with the engine compartment longitudinal beam 200, the center channel 400 and the battery pack 500. When the vehicle is involved in a collision, the collision force can be dispersed from the battery pack mounting front crossbeam 100 to the sill beam 300 and the center channel 400, which reduces the risk of the front engine compartment of the vehicle squeezing the battery pack 500, improves the safety and reliability of the battery pack 500 and the vehicle, and the battery pack mounting front crossbeam 100 has a simple structure and is lightweight, which is conducive to improving the vehicle's lightweight performance and economy.
