[0001] The utility model relates to the technical field of electric heavy trucks, in particular to a frame assembly and a vehicle. Background Art

[0002] Electric vehicle technology is also gaining traction in the commercial vehicle sector, particularly in heavy-duty trucks. The battery packs of electric heavy-duty trucks were initially located behind the cab, which reduced cargo space, impacted vehicle hauling capacity, and resulted in illogical overall load distribution. Recently, some battery cell-frame integration technologies have emerged, effectively addressing these issues by placing battery frames on both sides and the bottom of the frame. However, the inherent structure of the frame itself does not align well with that of the battery frame, resulting in low space utilization for the battery frame and limiting the range of heavy-duty trucks. Utility Model Content

[0003] The first aspect of the present invention provides a frame assembly to solve the defect of low space utilization of the battery frame in the prior art. By setting a herringbone connection structure to connect the battery frame between the main beam of the front section of the frame and the main beam of the rear section of the frame, the occupation of the internal space of the battery frame by the frame can be reduced, the structural fit between the frame and the battery frame can be improved, and the utilization of the internal space of the battery frame can be improved.

Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

[0043] Figure 1 This is a schematic diagram of the axle side of the frame assembly provided by an embodiment of the present utility model; Figure 2 It is a top view of the frame assembly provided by an embodiment of the utility model; Figure 3 It is a partial axle-side schematic diagram of a vehicle frame assembly provided by an embodiment of the utility model; Figure 4 It is a partial top view of the frame assembly provided by an embodiment of the utility model.

[0044] See Figures 1 to 4 The first aspect of an embodiment of the present invention provides a frame assembly, which includes a front frame main beam 100, a rear frame main beam 200, a battery frame 300 and a herringbone connection structure 400. The herringbone connection structure 400 is passed through the top of the battery frame 300 and is fixedly connected to the battery frame 300. The front frame main beam 100 is connected to one end of the herringbone connection structure 400, and the rear frame main beam 200 is connected to the other end of the herringbone connection structure 400.

[0045] It can be understood that in the frame assembly provided by the embodiment of the present invention, by arranging the battery frame 300 and the herringbone connection structure 400 between the front main beam 100 of the frame and the rear main beam 200 of the frame, the frame assembly can be formed into a three-section structure. During the production process, the three-section structure can be divided into three modules, which can be designed and manufactured separately, thereby realizing modular design and assembly, which can effectively improve the production efficiency of the frame assembly and reduce the difficulty of production.

[0046] In addition, the herringbone connection structure 400 is small in size and has good properties such as bending resistance, torsion resistance and stiffness. It can effectively reduce the occupancy of the internal space of the battery frame 300 while meeting the load requirements of the frame assembly, and can improve the utilization rate of the internal space of the battery frame 300 to place more battery cells 700. When the frame assembly is applied to an electric heavy-duty truck, it can effectively improve the cruising range of the electric heavy-duty truck.

[0047] Compared with the prior art in which the vehicle frame is directly inserted into the battery frame 300, the vehicle frame assembly provided by the embodiment of the present invention connects the battery frame 300 between the front main beam 100 and the rear main beam 200 of the frame by setting a herringbone connection structure, which can reduce the occupation of the internal space of the battery frame 300 by the vehicle frame, improve the structural fit between the vehicle frame and the battery frame 300, and improve the utilization rate of the internal space of the battery frame 300.

[0048] Continue reading Figure 2 In an optional embodiment of the present invention, the herringbone connection structure 400 includes a connecting longitudinal beam 410, a first herringbone connection component 420 and a second herringbone connection component 430. The connecting longitudinal beam 410 passes through the top of the battery frame 300. The first herringbone connection component 420 is arranged between the connecting longitudinal beam 410 and the main beam 100 of the front section of the frame, and is fixedly connected to the battery frame 300; the second herringbone connection component 430 is arranged between the connecting longitudinal beam 410 and the main beam 200 of the rear section of the frame, and is fixedly connected to the battery frame 300.

[0049] It can be understood that, compared with the two beams of the frame in the prior art, the separate connecting longitudinal beam 410 can effectively reduce the occupation of the internal space of the battery frame 300; further, by respectively arranging the first herringbone connection component 420 and the second herringbone connection component 430 at both ends of the connecting longitudinal beam 410, on the one hand, the bending resistance, torsion resistance and stiffness of the herringbone connection structure 400 can be made better, and on the other hand, the stress transfer between the connecting longitudinal beam 410 and the rear main beam 200 of the frame and the herringbone connection structure 400 can be made smoother, which can avoid structural damage or structural failure caused by stress concentration.

[0050] See Figures 1 to 4 In an optional embodiment of the present invention, the first herringbone connection assembly 420 includes a first connecting crossbeam 421, a first connecting side beam 422, and a second connecting side beam 423. The first connecting crossbeam 421 is perpendicularly arranged at one end of the connecting longitudinal beam 410 facing the front frame main beam 100; one end of the first connecting side beam 422 is arranged at the first end of the first connecting crossbeam 421 and connected to the front frame main beam 100, and the other end is connected to the connecting longitudinal beam 410; one end of the second connecting side beam 423 is arranged at the second end of the first connecting crossbeam 421 and connected to the front frame main beam 100, and the other end is connected to the connecting longitudinal beam 410. In other words, the first connecting side beam 422 and the second connecting side beam 423 are respectively arranged on both sides of the connecting longitudinal beam 410 and connected to the two beams of the front frame main beam 100.

[0051] It is understood that by arranging the first connecting side beam 422 and the second connecting side beam 423 on opposite sides of the connecting longitudinal beam 410 and disposing the first connecting cross beam 421 between the first connecting side beam 422 and the second connecting side beam 423, four force transmission paths can be formed between the connecting longitudinal beam 410 and the front frame main beam 100. This can effectively increase the upper limit of stress transmission between the connecting longitudinal beam 410 and the front frame main beam 100, improve the bending resistance, torsion resistance, and stiffness of the herringbone connection structure 400, and improve the load capacity of the herringbone connection structure 400. In addition, the first connecting cross beam 421 serves as the connection point between the connecting longitudinal beam 410, the first connecting side beam 422, the second connecting side beam 423, the front frame main beam 100, and the battery frame 300, providing a stable mounting base for the battery frame 300 and ensuring the reliability of the entire herringbone connection structure 400.

[0052] It can also be understood that the first connecting side beam 422 and the second connecting side beam 423 are respectively arranged at the two ends of the first connecting cross beam 421, and are connected to the main beam 100 of the front section of the frame and the connecting longitudinal beam 410 in a herringbone layout (triangular layout). This design not only achieves a close connection between the main beam 100 of the front section of the frame and the herringbone connection structure 400, but also effectively disperses the impact force and torque from the front through the mechanical advantages of the herringbone structure, thereby reducing the stress concentration phenomenon in the front section of the frame.

[0053] The four force transmission paths are explained below: the stress transmission order of the first path is the main beam of the front section of the frame 100-the first connecting side beam 422-the first connecting cross beam 421-the connecting longitudinal beam 410; the stress transmission order of the second path is the main beam of the front section of the frame 100-the first connecting side beam 422-the connecting longitudinal beam 410; the stress transmission order of the third path is the main beam of the front section of the frame 100-the second connecting side beam 423-the first connecting cross beam 421-the connecting longitudinal beam 410; the stress transmission order of the fourth path is the main beam of the front section of the frame 100-the second connecting side beam 423-the connecting longitudinal beam 410.

[0054] In addition, it can also be understood that when the vehicle wheelbase is adjusted, different wheelbases will cause different stresses on the connecting longitudinal beam 410. The first herringbone connection assembly 420 provided in the embodiment of the present invention can change the torque and stress on the connecting longitudinal beam 410 by adjusting the connection position of the first connecting side beam 422 and the second connecting side beam 423 with the connecting longitudinal beam 410 when the wheelbase of the vehicle changes. That is, the connection position between the first connecting side beam 422 and the second connecting side beam 423 and the connecting longitudinal beam 410 can change synchronously with the wheelbase of the vehicle. In this way, no matter how the wheelbase of the vehicle is adjusted, the force and torque on the connecting longitudinal beam 410 can be guaranteed to be within its own bearing range. In other words, the stability and reliability of the herringbone connection structure 400 can be guaranteed, and the frame assembly can meet more different working conditions.

[0055] See Figures 1 to 4 In an optional embodiment of the present invention, the second herringbone connection assembly 430 includes a second connecting crossbeam 431, a third connecting side beam 432, and a fourth connecting side beam 433. The second connecting crossbeam 431 is perpendicularly disposed at one end of the connecting longitudinal beam 410 facing the rear frame main beam 200. One end of the third connecting side beam 432 is disposed at the first end of the second connecting crossbeam 431 and connected to the rear frame main beam 200, and the other end is connected to the connecting longitudinal beam 410. One end of the fourth connecting side beam 433 is disposed at the second end of the second connecting crossbeam 431 and connected to the rear frame main beam 200, and the other end is connected to the connecting longitudinal beam 410. In other words, the third connecting side beam 432 and the fourth connecting side beam 433 are respectively disposed on either side of the connecting longitudinal beam 410 and connected to two beams of the rear frame main beam 200.

[0056] It is understood that by arranging the third connecting side beam 432 and the fourth connecting side beam 433 on opposite sides of the connecting longitudinal beam 410 and disposing the second connecting cross beam 431 between the third connecting side beam 432 and the fourth connecting side beam 433, four force transmission paths can be formed between the connecting longitudinal beam 410 and the rear frame main beam 200. This can effectively increase the upper limit of stress transmission between the connecting longitudinal beam 410 and the rear frame main beam 200, thereby improving the bending, torsional and rigidity properties of the herringbone connection structure 400 and increasing the load capacity of the herringbone connection structure 400. In addition, the second connecting cross beam 431, as the connection point between the connecting longitudinal beam 410, the third connecting side beam 432, the fourth connecting side beam 433, the rear frame main beam 200 and the battery frame 300, provides a stable mounting base for the battery frame 300 and ensures the reliability of the entire herringbone connection structure 400.

[0057] It can be understood that the third connecting side beam 432 and the fourth connecting side beam 433 are respectively arranged at the two ends of the second connecting cross beam 431, and are connected to the main beam 200 of the rear section of the frame and the connecting longitudinal beam 410 in a herringbone layout (triangular layout). This design not only achieves a close connection between the main beam 200 of the rear section of the frame and the herringbone connection structure 400, but also effectively disperses the impact force and torque from the rear through the mechanical advantages of the herringbone structure, thereby reducing the stress concentration phenomenon in the rear section of the frame.

[0058] The four force transmission paths are explained below: the stress transmission order of the first path is the main beam 200 of the rear section of the frame-the third connecting side beam 432-the second connecting cross beam 431-the connecting longitudinal beam 410; the stress transmission order of the second path is the main beam 200 of the rear section of the frame-the third connecting side beam 432-the connecting longitudinal beam 410; the stress transmission order of the third path is the main beam 200 of the rear section of the frame-the fourth connecting side beam 433-the second connecting cross beam 431-the connecting longitudinal beam 410; the stress transmission order of the fourth path is the main beam 200 of the rear section of the frame-the fourth connecting side beam 433-the connecting longitudinal beam 410.

[0059] In addition, it can be understood that when the wheelbase of the vehicle is adjusted, different wheelbases will cause different stresses on the connecting longitudinal beam 410. The second herringbone connection assembly 430 provided in the embodiment of the present invention can change the torque and stress on the connecting longitudinal beam 410 by adjusting the connection position of the third connecting side beam 432 and the fourth connecting side beam 433 with the connecting longitudinal beam 410 when the wheelbase of the vehicle changes. That is, the connection position between the third connecting side beam 432 and the fourth connecting side beam 433 and the connecting longitudinal beam 410 can change synchronously with the wheelbase of the vehicle. In this way, no matter how the wheelbase of the vehicle is adjusted, the force and torque on the connecting longitudinal beam 410 can be guaranteed to be within its own tolerance range. In other words, the stability and reliability of the herringbone connection structure 400 can be guaranteed, and the frame assembly can meet more different working conditions.

[0060] Continue reading Figure 2 In an optional embodiment of the present invention, the center line of the herringbone connection structure 400 coincides with the center line of the top of the battery frame 300. It can be understood that such a setting ensures the structural balance and symmetry of the frame assembly. This design not only improves the aesthetics of the frame, but more importantly, it optimizes the mechanical distribution of the frame assembly, so that the frame assembly can disperse stress more evenly when bearing load, reducing the risk of local stress concentration, thereby enhancing the overall strength and durability of the frame assembly.

[0061] Secondly, the overlapping axis design helps improve the stability and handling of the frame assembly. During driving, especially in complex road conditions, the frame assembly must withstand forces and torques from all directions. The alignment of the axis of the herringbone connection structure 400 with the top centerline of the battery frame 300 enables the frame assembly to better resist the effects of these forces and torques, maintaining vehicle stability and handling, and improving driving safety and comfort.

[0062] In addition, this design also helps to simplify the manufacturing and assembly process of the frame assembly. Since the herringbone connection structure 400 coincides with the top center line of the battery frame 300, the precise positioning and assembly of the various components of the frame assembly can be more easily achieved during the assembly process, thereby improving production efficiency and product quality.

[0063] Figure 5 It is a schematic cross-sectional structural diagram of a vehicle frame assembly provided by an embodiment of the present utility model.

[0064] See Figure 3 and Figure 5 In an optional embodiment of the present invention, the frame assembly further includes a double-layer connecting frame 500, which is passed through the battery frame 300 and fixedly connected to the battery frame 300; the double-layer connecting frame 500 is located directly below the connecting longitudinal beam 410 and is fixedly connected to the connecting longitudinal beam 410.

[0065] It is understandable that by providing a double-layer connecting frame 500, a force transmission path can be constructed below the connecting longitudinal beam 410, which can provide an additional support layer for the frame assembly and significantly enhance the torsional strength and anti-roll capability of the frame assembly. In addition, the double-layer connecting frame 500 not only optimizes the mechanical distribution of the frame assembly, but also further enhances the connection strength between the herringbone connecting structure 400 and the front main beam 100 and the rear main beam 200 of the frame. This design ensures the integrity and stability of the frame assembly when subjected to heavy loads or complex working conditions. In addition, the introduction of the double-layer connecting frame 500 also provides additional protection for the battery frame 300. During vehicle driving, the double-layer connecting frame 500 can absorb and disperse impacts and vibrations from the road surface, reducing the stress on the battery frame 300, thereby extending the service life of the battery and improving the overall performance and safety of the vehicle.

[0066] Figure 6 It is a structural schematic diagram of a truss assembly provided by an embodiment of the present utility model.

[0067] See Figure 1 and Figure 6In an optional embodiment of the present invention, the vehicle frame assembly further includes a truss assembly 600, which is disposed within the battery frame 300. One end of the truss assembly 600 abuts the battery frame 300, and the other end abuts the double-layer connecting frame 500. The truss assembly 600 is used to accommodate the battery cells 700. The figure shows four truss assemblies 600; it is understood that the addition of the truss assembly 600 greatly enhances the structural strength of the interior of the battery frame 300. At the same time, the abutment of the battery frame 300 and the double-layer connecting frame 500 against the truss assembly 600 ensures the stability and safety of the truss assembly 600, thereby protecting the battery frame 300 and the battery cells 700 therein from external shock and vibration.

[0068] Continue reading Figure 6 In an optional embodiment of the present invention, the truss assembly 600 includes a plurality of trusses 610 arranged at intervals, and an accommodating space is defined between any two adjacent trusses 610, and the accommodating space is used to arrange the battery cells 700. It can be understood that through the plurality of trusses 610 arranged at intervals, the frame assembly can more accurately control the arrangement and distribution of the battery cells 700. This layout not only makes the intervals between the battery cells 700 uniform, but also can make full use of the space inside the battery frame 300, thereby improving the energy density of the battery pack.

[0069] Continue reading Figure 6 In an optional embodiment of the present invention, the frame assembly further includes a water-cooling plate 800. The water-cooling plate 800 is provided on the truss 610 and is located on the side of the accommodating space. The water-cooling plate 800 is used to cool the battery cells 700. It can be understood that the water-cooling plate 800 can quickly absorb and take away the heat generated by the battery cells 700 by directly contacting the battery cells 700 or the air around the battery cells 700, thereby ensuring that the temperature distribution of the battery cells 700 in the entire battery pack is more uniform, effectively reducing the operating temperature of the battery, and thus extending the service life of the battery.

[0070] In optional embodiments of the present invention, reinforcing ribs or wing plates can be adaptively added to the connection points of the components in the aforementioned embodiments to improve the strength of the connection points. Specifically, the settings can be adaptively made according to actual conditions.

[0071] In an optional embodiment of the present invention, each of the aforementioned components can be adaptively arranged with weight-reducing holes to achieve a lightweight design. Specifically, the design can be adaptive according to actual conditions.

[0072] A second aspect of an embodiment of the present utility model provides a vehicle, which includes the frame assembly described in any one of the aforementioned embodiments. It can be understood that the frame assembly provided in this embodiment also has the beneficial effects of the frame assembly in any one of the aforementioned embodiments because it includes the frame assembly described in any one of the aforementioned embodiments. The specific beneficial effects can be found in the above description, and will not be repeated here.

[0073] It should be noted that the technical solutions in the various embodiments of the present invention can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in this field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist, that is, it does not fall within the scope of protection of the present invention.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
