[0039] This utility model proposes a vehicle frame assembly.

[0040] Please see Figures 1 to 5 In one embodiment of the present invention, the frame assembly includes two spaced longitudinal beams 100, at least one crossbeam 200, and a battery pack 300. The longitudinal beams 100 have an inner web surface 110 and a lower flange surface 130 located below the inner web surface 110. As a load-bearing component, the longitudinal beams 100 are typically composed of three parts: an upper flange (a horizontal plate at the top), a web plate (a vertical plate in the middle), and a lower flange (a horizontal plate at the bottom). The cross-section of the longitudinal beams 100 is "U"-shaped. The inner web surface 110 is the vertical part of the "U". The plate surface inside the groove of the "U" is the plate surface of the part of the two longitudinal beams 100 facing each other. The lower flange surface 130 is the plate surface of the horizontal part at the bottom of the "U".

[0041] A crossbeam 200 is disposed between the two inner web surfaces 110, and at least one crossbeam is disposed therein. In the case of multiple crossbeams 200, they are spaced apart along the extension direction of the two longitudinal beams 100. Compared to the conventional solution of placing the crossbeam 200 on the upper flange of the longitudinal beam 100, placing it between the two inner web surfaces 110 allows it to directly participate in load transfer and distribution, enabling the load to be evenly transferred between the two longitudinal beams 100 through the crossbeam 200, thus avoiding localized stress concentration.

[0042] Furthermore, the crossbeams 200 between the inner surfaces 110 provide stronger torsional restraint, preventing the longitudinal beams 100 from twisting under lateral forces. Positioning the crossbeams 200 between the inner surfaces 110 fully utilizes the internal space of the longitudinal beams 100, reducing the need for external additional structures. This design not only saves materials but also reduces the overall structural weight, contributing to lightweighting. Since lightweight design is a key objective in vehicle manufacturing, the arrangement between the inner surfaces 110 achieves better lightweighting while maintaining strength.

[0043] Furthermore, when the crossbeam 200 is positioned between the inner web surfaces 110, modular assembly can be achieved through standardized connection methods (such as bolts, welding, etc.). This design facilitates production and installation, while also improving the scalability of the structure.

[0044] In this embodiment, the crossbeam 200 is configured as a crossbeam plate, which reduces the space occupied in the Z-direction of the vehicle, i.e., the vertical direction of the battery pack 300, thereby facilitating an increase in the capacity of the battery pack 300 to meet the high power requirements of electric vehicles. It also facilitates the integrated installation of communication harnesses, power harnesses, and high-voltage boxes, providing space. In other embodiments, the crossbeam 200 is a tubular beam, square beam, or similar material.

[0045] The battery pack 300 includes a battery box 310 and battery modules 330. The battery box 310 has at least two receiving cavities 320 distributed in the vertical direction, and each receiving cavity 320 contains one battery module 330; thus, it has a larger capacity to meet the vehicle's range requirements. The battery pack 300 is typically rectangular and has a bottom surface, with the vertical direction being the same as the vertical direction when the bottom surface is placed on the ground, which is also the Z-axis of the vehicle.

[0046] The battery box 310 has two outer side walls 311 of the parallel longitudinal beam 100. The outer side walls 311 are provided with mounting parts 312. The two outer side walls 311 are connected to the two longitudinal beams 100 respectively through the mounting parts 312, thereby fixing the battery pack 300 to the two longitudinal beams 100.

[0047] The battery box 310 has a battery box 310 and a cover that covers the battery box 310. In this embodiment, the outer wall 311 is the outer wall of the battery box 310, that is, the outer wall surface along the extension direction of the longitudinal beam 100; in other embodiments, if the cover has sufficient strength, it can also be the outer wall surface of the cover.

[0048] Reference Figure 3 and Figure 5 The outer side wall 311 is provided with a mounting part 312. The two outer side walls 311 are connected to the two lower wing surfaces 130 respectively through the mounting part 312, thereby fixing the battery pack 300 to the two longitudinal beams 100.

[0049] The location and design of the mounting part 312 need to meet the requirements of structural strength, installation convenience, and space utilization. In this embodiment, the mounting part 312 is located near the middle of the outer wall 311, placing it in the middle position of the outer wall 311, close to the center of gravity of the battery box 310 (the top of the battery box 310). This arrangement can optimize load distribution and reduce local stress concentration on the longitudinal beam 100. In other embodiments, the mounting part 312 can be located in the upper region of the outer wall 311, near the top of the battery box 310; or the mounting part 312 can be located in the lower region of the outer wall 311, near the bottom of the battery box 310.

[0050] Multiple mounting parts 312 are provided at different heights on the outer side wall 311 to form multi-point fixation. This arrangement can further enhance the deformation resistance and overall stability of the battery box 310. Of course, multiple mounting parts can also be provided at the same height along the extension direction on the outer side wall 311.

[0051] Specifically, the specific structural form of the mounting part 312 needs to be designed according to the connection method, stress conditions, and manufacturing process. In one embodiment, the mounting part 312 is designed as an outwardly protruding boss for direct contact with the lower flange 130 of the longitudinal beam 100. In another embodiment, the mounting part 312 is designed as a flange with holes for connection to the longitudinal beam 100 via bolts or other fasteners. In this embodiment, a fixing beam 313 is added to the outer side wall 311. The fixing beam 313 acts as a reinforcing rib, and the mounting part 312 is integrated into the fixing beam 313. This design can improve the load-bearing capacity of the mounting part 312 and enhance the overall rigidity of the battery box 310.

[0052] The outer wall 311 of the battery pack 310 is connected to the longitudinal beam 100 via the mounting part 312. Furthermore, a support frame can be provided on the lower flange 130 to form a stable fixing point. The design position and connection method of the mounting part 312 are optimized to ensure that the battery pack 300 is well constrained in both the vertical and lateral directions. The battery pack 300 can remain stable under dynamic load conditions (such as sudden braking, turning, or bumpy road conditions), reducing the impact on the internal battery module 330. The connection between the battery pack 300 and the lower flange 130 of the longitudinal beam 100 via the mounting part 312 allows the load to be evenly transferred to the frame, avoiding local stress concentration. The connection method between the mounting part 312 and the longitudinal beam 100 can effectively absorb external impact forces, protecting the battery module 330 from damage.

[0053] The housing cavity 320 of the battery box 310 is designed with a modular structure, which facilitates the installation and replacement of the battery module 330. The connection method between the mounting part 312 and the longitudinal beam 100 (such as bolt connection or snap connection) is simple and efficient, and suitable for mass production.

[0054] The technical solution of this utility model provides stronger torsional restraint through the crossbeam 200 between the inner surfaces 110, preventing the longitudinal beam 100 from twisting under lateral forces; and by placing the crossbeam 200 between the inner surfaces 110, the internal space of the longitudinal beam 100 can be fully utilized, reducing the need for external additional structures. This design not only saves materials but also reduces the weight of the overall structure, which is beneficial for lightweighting; the battery pack 300 includes a battery box 310 and a battery module 330. The battery box 310 has at least two receiving cavities 320 distributed in the vertical direction, and each receiving cavity 320 contains a battery module 330; this can meet the vehicle's long-range requirements; the battery box 310 has a flat... The two outer side walls 311 of the longitudinal beam 100 are provided with mounting parts 312. The two outer side walls 311 are connected to the two lower flanges 130 respectively through the mounting parts 312, and the battery pack 300 is fixed to the two longitudinal beams 100. The longitudinal beams 100, the crossbeams 200 and the battery box 310 are connected to form a cooperative force-bearing system, which jointly bears longitudinal, lateral and torsional loads. This solves the problems of large redundant weight, low space utilization and insufficient modal stiffness caused by the independent design of the frame and the battery pack 300 in the traditional solution. Moreover, the battery pack 300 is placed under the frame longitudinal beams 100, freeing up the outer space to adapt to the range-extended / hydrogen fuel system. The same frame is compatible with pure electric / range-extended / hydrogen fuel vehicle models, and the production line modification cost is reduced.

[0055] Reference Figure 2 and Figure 4 Furthermore, a reserved space 400 is provided between the bottom of the crossbeam 200 and the top of the battery box 310. On the one hand, the crossbeam 200 is connected to the bottom of the battery box 310 and the longitudinal beam 100 to form a closed space structure. The existence of the space reduces the transmission of vibration from the frame to the battery pack 300, and reduces the risk of fatigue damage to the battery module 330 and connecting components. On the other hand, the reserved space 400 provides sufficient operating space for installation and maintenance, and simplifies the process flow.

[0056] Furthermore, at least a portion of the battery box 310 is disposed between the two longitudinal beams 100. In one embodiment, the mounting portion 312 of the battery box 310 is connected to the longitudinal beam 100, and the entire wall of the battery box 310 is located between the two longitudinal beams 100, thereby facilitating the installation of the two accommodating cavities 320 in the vertical direction. In one embodiment, the portion of the battery box 310 above the connection between the mounting portion 312 and the longitudinal beam 100 is located between the two longitudinal beams 100, and the portion of the battery box 310 below the connection between the mounting portion 312 and the longitudinal beam 100 is located below the two longitudinal beams 100. Thus, by partially setting up the battery box 310 while retaining the reserved space 400, the internal space of the vehicle frame can be maximized, avoiding the additional occupation of other areas. By placing part of the battery box 310 between the longitudinal beams 100, the center of gravity of the vehicle can be significantly lowered, driving stability can be improved, and the protection of the battery box 310 can be enhanced. The battery box 310 is connected to the lower flange 130 of the longitudinal beam 100 through the mounting part 312, ensuring that the load can be transferred to the entire frame through the longitudinal beam 100.

[0057] Reference Figure 2 and Figure 4 Furthermore, the frame assembly also includes multiple mounting brackets 500. At least two mounting brackets 500 are spaced apart on the outer web surface 120 of a longitudinal beam 100 along the extension direction of the longitudinal beam 100. The mounting brackets 500 connect to the mounting portion 312 to mount the battery pack 300 below the two longitudinal beams 100. The battery pack 300 is typically heavy, and if the connection between the outer wall 311 of the battery box 310 and the lower flange 130 of the longitudinal beam 100 is relied upon alone, it may lead to local stress concentration. The mounting brackets 500 can distribute the load of the battery pack 300 to different positions on the longitudinal beam 100, thereby reducing local stress. The multiple mounting brackets 500 are arranged at intervals along the extension direction of the longitudinal beam 100 to form a multi-point support structure. In long-span frames or heavy-duty vehicles, this design can significantly improve the load-bearing capacity of the frame.

[0058] Different types of mounting brackets 500 (such as bolted, welded, or snap-fit ​​connections) can adapt to different assembly processes; the number and position of mounting brackets 500 can be customized according to the size and weight of the battery pack 300.

[0059] Reference Figure 2 and Figure 4Specifically, the longitudinal beam 100, the crossbeam 200, the mounting bracket 500, and the outer frame of the battery box 310 form a first closed structure (H-shaped), while the battery box 310 has two accommodating cavities 320 in the vertical direction. The longitudinal beam 100, the crossbeam 200, the mounting bracket 500, and the two accommodating cavities 320 inside the battery box 310 constitute a second closed structure (H-shaped). In this way, the mounting bracket 500 can evenly transfer the load of the battery pack 300 to different positions of the longitudinal beam 100, thereby improving the mechanical performance of the frame and effectively enhancing the modal stiffness of the whole vehicle.

[0060] The enclosed structure significantly improves the overall rigidity of the frame, especially in terms of bending and torsional resistance. The H-shaped layout enhances structural stability through multi-point support and evenly distributed force transmission paths. The first enclosed structure forms the basic rigidity through the external frame (longitudinal beams 100, crossbeams 200, mounting brackets 500, and the outer frame of the battery box 310). The second enclosed structure further refines the force transmission path and optimizes mechanical performance through the internal cavity 320.

[0061] Specifically, to optimize the force transmission path, the battery box 310 has a support plate 340 that divides the space into upper and lower accommodating cavities 320. The connection between the support plate 340 and the battery box 310 is located near the mounting portion 312. This allows the force transmitted from the longitudinal beam 100 to the mounting portion 312 to form a three-way path through the support plate 340 and the battery box 310.

[0062] Furthermore, to enhance the structural strength of the connection between the longitudinal beam 100 and the mounting bracket 500, the frame assembly also includes a reinforcing member 600. The reinforcing member 600 is disposed between the inner web surface 110 and the crossbeam 200, and is fixedly connected to the longitudinal beam 100, at least on the inner web surface 110. By increasing material thickness or providing additional support, the reinforcing member 600 significantly improves the load-bearing capacity of the connection between the longitudinal beam 100 and the mounting bracket 500.

[0063] Reference Figures 1 to 5Specifically, the reinforcing member 600 includes a first connecting section 610 and a second connecting section 620. The first connecting section 610 is connected to the inner web surface 110, and the second connecting section 620 is bent from the longitudinal beam 100 where the first connecting section 610 is located toward another longitudinal beam 100. The two second connecting sections 620 are disconnected from each other. Both the first connecting section 610 and the second connecting section 620 are connected to the crossbeam member 200. The first connecting section 610 is directly connected to the inner web surface 110 of the longitudinal beam 100, forming the main fixing point, which firmly fixes the reinforcing member 600 to the longitudinal beam 100, ensuring that the force can be transmitted to the entire frame through the inner web surface 110. The two second connecting sections 620 are disconnected from each other to avoid material waste. The main function of the second connecting section 620 is to connect with the crossbeam member 200, further enhancing the support capacity of the crossbeam member 200.

[0064] Specifically, the crossbeam member 200 includes a transverse section 210 extending from both ends toward the two longitudinal beams 100, and a fixing section 220 disposed at both ends of the transverse section 210 and bent therebetween. The two fixing sections 220 are respectively connected to the two inner web surfaces 110. A first connecting section 610 is riveted to the fixing section 220, and two second connecting sections 620 are riveted to the transverse section 210. The transverse section 210 is the core part of the crossbeam member 200, extending from both ends toward the two longitudinal beams 100. The fixing sections 220 are disposed at both ends of the transverse section 210 and bent therebetween. The main function of the fixing sections 220 is to connect with the inner web surfaces 110 of the longitudinal beams 100 to form stable fixing points. The first connecting section 610 is riveted to the fixing section 220 to ensure a tight connection between the reinforcing member 600 and the crossbeam member 200. The first connecting section 610 is connected to the inner surface 110, and the second connecting section 620 is connected to the transverse section 210, forming a complete force transmission path to ensure that the load can be evenly distributed to the entire frame through the reinforcing member 600 and the crossbeam member 200.

[0065] Specifically, the reinforcing member 600, the crossbeam member 200, and the frame are fixed together by multiple rivets. Riveting is a high-strength connection method that can simplify the assembly process while ensuring strength.

[0066] Reference Figure 2 and Figure 3 Furthermore, to reduce the width of the battery box 310 so that it can be positioned between the two longitudinal beams 100, the frame assembly also includes an adapter bracket 700, which connects the mounting bracket 500 and the mounting portion 312. The adapter bracket 700 adjusts the position and angle of the mounting plate 710, allowing the battery box 310 to be positioned more compactly between the two longitudinal beams 100. By adjusting the angle and position of the mounting plate 710, the adapter bracket 700 extends the mounting portion 312 of the battery box 310 outwards, thereby reducing the actual width of the battery box 310.

[0067] To ensure structural strength, the adapter bracket 700 includes two mounting plates 710 stacked at intervals in the vertical direction of the vehicle frame and several sleeves 720. The sleeves 720 are embedded in and pass through the two mounting plates 710, enclosing a cavity structure. The two mounting plates 710 connect the mounting bracket 500 and the mounting portion 312, respectively. The mounting plates 710 are stacked at intervals in the vertical direction of the vehicle frame, connecting the mounting bracket 500 and the mounting portion 312 of the battery box 310. The upper mounting plate 710 connects to the mounting bracket 500, and the lower mounting plate 710 connects to the mounting portion 312 of the battery box 310. As the connecting component between the mounting bracket 500 and the battery box 310, the adapter bracket 700 needs to withstand significant loads, especially under dynamic operating conditions. The sleeves 720, embedded in and passing through the two mounting plates 710, provide fixation and support. The sleeves 720 and the mounting plates 710 enclose a cavity structure, enhancing the overall rigidity of the adapter bracket 700. The cavity structure is formed by the sleeve 720 and the mounting plate 710. The design of the cavity structure reduces the amount of material used while maintaining high strength, and has the characteristics of being lightweight and high-strength.

[0068] Reference Figure 2 and Figure 4 Furthermore, the battery pack 300 includes a battery box 310, a support plate 340, and two battery modules 330. The battery box 310 has an installation space, and the support plate 340 is disposed in the battery box 310, separating the installation space to form two vertically distributed receiving cavities 320. The two battery modules 330 are respectively installed in the two receiving cavities 320. The battery box 310 includes a base plate 350, which is parallel to the support plate 340. Liquid cooling channels 360 for the battery modules 330 are integrated on the base plate 350 and the support plate 340 of the battery pack 300. The integrated liquid cooling channels 360 are used for cooling the battery modules 330. After integrating the liquid cooling channels 360, the base plate 350 not only provides mechanical support but also undertakes the function of heat exchange. The liquid cooling system is integrated with the battery pack 300, reducing the need for external piping connections. The liquid cooling channel 360 is integrated into the base plate 350 and the support plate 340, avoiding the need for additional cooling modules and achieving a compact layout.

[0069] Specifically, the battery box 310 is integrally formed of aluminum material, and a fixing beam 313 connected to the mounting bracket 500 is integrally formed on the outer side of the battery box 310. The mounting part 312 is configured as the fixing beam 313.

[0070] This utility model also proposes a vehicle including a frame assembly. The specific structure of the frame assembly is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here. The vehicle is suitable for pure electric, hydrogen fuel cell, and hybrid vehicle models.
