[0024] <EMBODIMENT>

[0025] As shown in Figure 1 and Figure 2 , in the embodiment, the side-arranged cage type power battery frame is arranged on the vehicle frame 20 of the vehicle, and includes two sub-frames, four pairs of mounting brackets 16 and four mounting cross beams 1.

[0026] As shown in Figure 1 and Figure 2 , the two sub-frames are symmetrically arranged on the two sides of the vehicle frame 20; each sub-frame is a cuboid cage type structure, and contains a frame body, two tray assemblies 7, a top skin 12, a side skin 11, an end skin 5 and a bottom guard plate 8.

[0027] The frame body contains four vertical beams, two cross beams 3, two longitudinal beams 13, a plurality of top cross beams 9 and a plurality of side cross beams 10.

[0028] Four vertical beams, including beams 2, 6, 14, and 15, are located at the four corners of the pallet assembly 7. The lower end and middle section of each vertical beam are connected to two pallet assemblies 7, respectively. In this embodiment, vertical beams 2 and 15, located near the frame 20, are provided with cable guide holes. The four vertical beams are connected to the pallet assembly 7 by bolts, increasing structural stability while reducing stress deformation caused by large-area welding and improving the overall frame manufacturing precision.

[0029] Two crossbeams 3 are located at the two ends of the pallet assembly 7 respectively; the two ends of each crossbeam 3 are connected to the upper ends of the corresponding two vertical beams respectively, specifically: the two ends of one crossbeam 3 are connected to the upper ends of vertical beam 2 and vertical beam 6 respectively, and the two ends of the other crossbeam 3 are connected to the upper ends of vertical beam 14 and vertical beam 15 respectively.

[0031] Multiple top crossbeams 9 are arranged at equal intervals along the longitudinal direction of the frame 20, and the two ends of each top crossbeam 9 are connected to two longitudinal beams 13 respectively.

In this way, the top skin can support stepping, thereby eliminating the need to set up an operating platform for the whole vehicle, thus reducing the types of vehicle parts.

[0035] The side skin 11 is located on the side of the frame. In this embodiment, both the top skin 12 and the side skin 11 adopt a segmented structure, which simplifies the processing and manufacturing process and makes it easier to ensure the overall flatness; moreover, it makes the size of a single skin small, which is convenient for transportation.

[0038] like Figure 1 and Figure 2 As shown, four pairs of mounting brackets 16 are arranged at equal intervals along the longitudinal direction of the frame 20 for mounting two subframes onto the frame 20.

[0039] Each pair of mounting brackets 16 is connected to the side of two sub-frames near the vehicle frame 20. Specifically, the upper end of each mounting bracket 16 is connected to the corresponding longitudinal beam 13, and the lower end and middle part are connected to two tray assemblies 7 respectively. In this embodiment, the cross-section of the mounting bracket 16 is U-shaped. Of course, the mounting bracket 16 can also be made of profile according to actual needs.

[0041] In this embodiment, as Figure 2 As shown, one sub-frame also has a step 18 and a handrail 19 for boarding, and another sub-frame has a charging socket 21, resulting in a high degree of overall integration.

[0042] In this embodiment, the assembly of the side-mounted cage-type power battery frame adopts an offline sub-assembly method, and the assembly process is as follows:

[0043] Step S1, separate the tray assembly 7 and the power battery 17, as follows: Figure 3 As shown.

[0044] Step S2: Assemble vertical beams 2, 6, 14, and 15 at the four corners of the pallet assembly 7.

[0045] Step S3: Assemble two horizontal beams 3 and two vertical beams 13 on the top of vertical beams 2, 6, 14 and 15.

[0047] Step S5: Hoist the two sub-frames onto both sides of the frame 20, and simultaneously install the crossbeam 1 at the bottom of the frame 20, thus completing the assembly of the side-mounted cage-type power battery frame. Figure 2 As shown.

[0048] Functions and effects of the embodiments

[0049] According to the side-mounted cage-type power battery frame and vehicle involved in this embodiment, since the two sub-frames are symmetrically arranged on both sides of the vehicle frame, each sub-frame is a cuboid cage structure, including a frame body and two tray assemblies arranged vertically and spaced apart within the frame body. Multiple pairs of mounting brackets are arranged longitudinally and spaced apart along the vehicle frame. Each pair of mounting brackets is connected to the side of the two sub-frames near the vehicle frame, which can mount the two sub-frames on the vehicle frame. On the one hand, the cage structure provides good overall structural stability and strength; on the other hand, the side-mounted arrangement lowers the center of gravity of the vehicle and makes the weight distribution of the chassis accessories more reasonable, improving the handling stability of the vehicle. It also frees up some space above the chassis, which can be used to increase the cargo box volume.

[0050] In addition, because it also includes multiple mounting beams, which correspond to multiple pairs of mounting brackets and are located under the frame, with each mounting beam having two ends connected to the lower ends of the corresponding pair of mounting brackets, the overall torsional energy of the frame is improved, and the overall rigidity of the frame is increased.

[0051] Furthermore, because the frame contains four vertical beams, two horizontal beams, and two longitudinal beams, the four vertical beams are located at the four corners of the pallet assembly, and the lower end and middle part of each vertical beam are connected to two pallet assemblies respectively. The two horizontal beams are located at the two ends of the pallet assembly, and the two ends of each horizontal beam are connected to the upper ends of the corresponding two vertical beams respectively. The two longitudinal beams are located on the two sides of the pallet assembly, and the two ends of each longitudinal beam are connected to the upper ends of the corresponding two vertical beams respectively. The structure is simple and easy to install.

[0052] In addition, because the frame also contains multiple top crossbeams and multiple side crossbeams, the multiple top crossbeams are arranged at intervals along the longitudinal direction of the frame, and the two ends of each top crossbeam are connected to two longitudinal beams respectively. The multiple side crossbeams are also arranged at intervals along the longitudinal direction of the frame, and the upper end of each side crossbeam is connected to the corresponding longitudinal beam, while the lower end and the middle part are connected to two pallet assemblies respectively. This further improves the overall torsional energy of the frame and increases the overall stiffness of the frame.

[0053] In addition, because the sub-frame further comprises a top skin, a side skin, an end skin and a bottom shield respectively arranged at the top, the side, the end and the bottom of the frame body, the risk of invalidation of the power battery caused by rainwater and dust entering the frame body is avoided, and the risk of the power battery in the frame body being impacted by gravel is also avoided.

[0054] In addition, because the top skin is installed on the top of the frame body through the skin fixing framework, the skin fixing framework is a cross structure, the carrying strength of the top skin is improved, the top skin can support the stepping, and thus the operation platform of the whole vehicle is no longer needed, thereby reducing the types of parts of the whole vehicle.

[0055] In addition, because the top skin and the side skin are both segmented structures, the processing and manufacturing are simpler, and the overall flatness is easy to ensure; moreover, the size of the single skin is small, and the transportation is convenient.

[0056] In addition, because the sub-frame further comprises the bottom shield arranged at the bottom of the frame body, the bottom of the frame body is well protected, and the safety of the battery frame is further improved.

[0057] In addition, because the sub-frame is further provided with the boarding steps, the boarding handrails and the charging socket, the overall integration is high, and the whole vehicle has great convenience.

[0058] The above-mentioned embodiments are preferred cases of the utility model, and are not used to limit the protection scope of the utility model.
