[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 A vehicle frame assembly 100 according to an embodiment of a first aspect of the present invention is described.

[0021] like Figure 1-Figure 5As shown, the frame assembly 100 according to the first embodiment of the present invention comprises: a first frame section 1 , a second frame section 2 and a third frame section 3 .

[0022] Specifically, if Figure 2-Figure 5 As shown, the first frame section 1 includes a tray section 11 and a plurality of first connecting portions 12, wherein the plurality of first connecting portions 12 are respectively arranged on the tray section 11 in a first direction (for example, Figure 4 The tray segment 11 has a receiving cavity 13 on both sides of the first frame segment 1 in the first direction (for example, the left and right directions), and the receiving cavity 13 is provided with a battery pack 4. The second frame segment 2 is provided on one side of the first frame segment 1 in the first direction, and the second frame segment 2 includes a second connecting portion 21, which is connected to the first connecting portion 12 in the second direction (for example, Figure 4 The third frame segment 3 is arranged on the other side of the first frame segment 1 in the first direction, and the third frame segment 3 includes a third connecting portion 31, and the third connecting portion 31 is connected to one side of the first connecting portion 12 in the second direction. In the description of the present invention, the meaning of "plurality" is two or more.

[0023] Each first connection portion 12 is disposed in a third direction (eg, Figure 4 The width in the up-down direction (in the vertical direction) gradually decreases in the direction away from the first frame segment 1, and the third direction, the second direction and the first direction are orthogonal to each other. The width in the third direction of at least one of the second connecting portion 21 and the third connecting portion 31 gradually increases in the direction toward the first frame segment 1.

[0024] For example, in Figure 2 and Figure 4 In the example of , the tray segment 11 is roughly a rectangular frame structure, the number of first connection parts 12 is 4, the 4 first connection parts 12 are respectively arranged at the 4 corners of the tray segment 11, and each first connection part 12 extends along the first direction. The shape of each first connection part is roughly trapezoidal, that is, the width of the end of the first connection part adjacent to the tray segment is larger, and the width of the end of the first connection part away from the tray segment is smaller.

[0025] The width of one of the second connecting portion 21 and the third connecting portion 31 in the third direction gradually increases along the direction toward the first frame segment 1 (not shown); or the width of the second connecting portion 21 and the third connecting portion 31 in the third direction gradually increases along the direction toward the first frame segment 1 (as shown in the figure). Figure 5 as shown).

[0026] Specifically, the second connection part 21 and the third connection part 31 are both roughly trumpet-shaped, that is, the width of the end of the second connection part 21 and the third connection part 31 away from the first frame segment is extremely large. When the frame assembly 100 is installed, the end of the first connection part 12 with a smaller width in the third direction is firstly connected with the end of the second connection part 21 or the third connection part 31 with a larger width in the third direction, and then the second connection part 21 or the third connection part 31 is pushed to be located on one side of the first connection part 12 in the second direction. In this way, the installation tolerance size of the first connection part 12 in the third direction is increased, the installation difficulty between the second frame segment 2 or the third frame segment 3 and the first frame segment 1 is reduced, and the installation efficiency of the frame assembly 100 is improved.

[0027] According to the frame assembly 100 of the embodiment of the present invention, by gradually reducing the width of the first connection portion 12 in the third direction in the direction away from the first frame segment 1, and gradually increasing the width of the second connection portion 21 and / or the third connection portion 31 in the third direction in the direction toward the first frame segment 1, the difficulty of installing the second frame segment 2 or the third frame segment 3 with the first frame segment 1 is reduced, and the installation efficiency of the frame assembly 100 is improved.

[0028] According to some embodiments of the present invention, a surface of at least one of the second connection portion 21 and the third connection portion 31 on one side in the third direction is an inclined surface, and the inclined surface extends obliquely downward in the first direction toward the first connection portion 12 .

[0029] During docking installation, the degree of fit between the inclined surface of the first connection part 12 and the inclined surface of the second connection part 21 or the third connection part 31 can be used to determine whether the first connection part 12 and the second connection part 21 or the third connection part 31 are in a suitable docking position. When the inclined surface of the first connection part 12 is completely fitted with the inclined surface of the second connection part 21 or the third connection part 31, that is, the second connection part or the third connection part is installed in place, the first connection part 12 and the second connection part 21 or the third connection part 31 can be fixed. Therefore, the setting of the inclined surface makes the connection between the first connection part 12 and the second connection part 21 or the third connection part 31 smoother and the installation is easier.

[0030] Specifically, a plurality of fixing holes 15 are provided on the first connection portion 12, the second connection portion 21 and the third connection portion 31, and the frame assembly 100 further includes a fastener 7, which is arranged in the fixing hole 15 to fix the first connection portion 12 to the second connection portion 21 or the third connection portion 31. Such an arrangement ensures the connection reliability between the first connection portion 12 and the second connection portion 21 or the third connection portion 31, and the arrangement of the fastener 7 and the fixing hole 15 is convenient to operate and has low cost.

[0031] Optionally, the inclined surface may be a side of the second connection portion 21 and / or the third connection portion 31 adjacent to the ground in the third direction, and in this case, a side of the second connection portion 21 and / or the third connection portion 31 away from the ground in the third direction may be a plane. In this way, the upper surface of the frame assembly is a plane, which is convenient for the installation of the frame and the vehicle body, while ensuring that the second connection portion 21 and / or the third connection portion 31 can present a trumpet-shaped structure.

[0032] According to some embodiments of the present invention, Figure 6 As shown, in the projection plane of the third direction, the angle between the inclined plane and the first direction is α, wherein α satisfies: 5°<α≤40°.

[0033] When α≤5°, the angle between the inclined surface and the first direction is small, that is, the installation tolerance size of the first connection part 12 in the third direction is small, which increases the difficulty of docking and installation of the first connection part 12 with the second connection part 21 or the third connection part 31; when α>40°, the angle between the inclined surface and the first direction is too large, the inclined surface is too inclined, which reduces the bearing strength of the docking point between the first connection part 12 and the second connection part 21 or the third connection part 31, and the angle between the inclined surface and the first direction is too large, which increases the size and weight of the second connection part 21 or the third connection part 31, which is not conducive to the lightweight design of the whole vehicle. Therefore, by making the angle α between the inclined surface and the first direction satisfy: 5°<α≤40°, the difficulty of docking and installation of the first connection part 12 with the second connection part 21 or the third connection part 31 is reduced, and the bearing strength of the docking point between the first connection part 12 and the second connection part 21 or the third connection part 31 is guaranteed.

[0034] Furthermore, if Figure 6 As shown, the minimum width of at least one of the second connection portion 21 and the third connection portion 31 in the third direction is L1, and the maximum width of at least one of the second connection portion 21 and the third connection portion 31 in the third direction is L2, wherein L1 and L2 satisfy: 2×(L2-L1)≤L1.

[0035] When 2×(L2-L1)>L1, the inclined surface is too inclined, which reduces the bearing strength of the joint between the first connection part 12 and the second connection part 21 or the third connection part 31, and increases the overall weight of the second connection part 21 or the third connection part 31, which is not conducive to the lightweight design of the whole vehicle. Therefore, by making the minimum width L1 and the maximum width L2 of at least one of the second connection part 21 and the third connection part 31 in the third direction satisfy: 2×(L2-L1)≤L1, both the appropriate installation tolerance size and the bearing strength of the joint between the first connection part 12 and the second connection part 21 or the third connection part 31 are guaranteed, which is conducive to the lightweight design of the whole vehicle.

[0036] According to some specific embodiments of the present invention, Figure 3 As shown, the pallet segment 11 includes a bottom plate 111 , two longitudinal beams 112 and a plurality of transverse beams 113 .

[0037] Specifically, two longitudinal beams 112 are respectively arranged on both sides of the bottom plate 111 in the second direction, the two longitudinal beams 112 are located above the bottom plate 111, and each longitudinal beam 112 includes a first connecting portion 12. A plurality of cross beams 113 are spaced apart in the first direction, and both ends of each cross beam 113 are respectively connected to the two longitudinal beams 112, and the bottom plate 111, the two longitudinal beams 112 and the plurality of cross beams 113 jointly define a receiving cavity 13.

[0038] In this way, the coordinated arrangement of the longitudinal beam 112 and the cross beam 113 makes the frame assembly 100 as a whole have better anti-deformation ability, ensuring the stability and reliability of the frame assembly 100. In addition, the bottom plate 111, the two longitudinal beams 112 and the plurality of cross beams 113 jointly define the accommodating cavity 13, which not only provides sufficient accommodating space for the installation of the battery pack 4, but also makes the overall structure of the frame assembly 100 more compact.

[0039] like Figure 3 As shown, there are five cross beams 113, and the five cross beams 113 are connected to the two longitudinal beams 112 at intervals along the first direction. Each cross beam 113 extends along the second direction. The bottom plate 111 is connected to the side of the longitudinal beams 112 and the cross beams 113 adjacent to the ground. The two cross beams 113, the two longitudinal beams 112 and the bottom plate 111 jointly define a receiving cavity 13, and the battery pack 4 can be placed in the receiving cavity 13. In this way, the ground clearance of the battery pack 4 is raised by about 90mm, and there is no need to provide an additional bottom protection plate for the battery pack 4. The bottom plate 111 of the tray section 11 can meet customer requirements. At the same time, the longitudinal beam 112 can serve as the side beam of the battery pack 4 tray, that is, the bottom protection plate, the tray side beam and the mounting bracket are cancelled, which greatly reduces the weight of the frame assembly 100 (about 35kg), thereby reducing the energy consumption of the vehicle.

[0040] Furthermore, if Figure 3 and Figure 5 As shown, the multiple cross beams 113 include multiple inner cross beams 1131 and multiple end cross beams 1132. The multiple end cross beams 1132 are respectively arranged on both sides of the bottom plate 111 in the first direction. The multiple inner cross beams 1131 are arranged between the multiple end cross beams 1132. The multiple inner cross beams 1131 divide the accommodating cavity 13 into a battery cell cavity 131 and a distribution cavity 132. The battery pack 4 includes a battery cell module 41 and a distribution box 42. The battery cell module 41 is arranged in the battery cell cavity 131, and the distribution box 42 is arranged in the distribution cavity 132.

[0041] Reference Figure 3-Figure 5The five cross beams 113 include three inner cross beams 1131 and two end cross beams 1132. The two end cross beams 1132 are connected to the two ends of the two longitudinal beams 112 in the first direction. The three inner cross beams 1131 are arranged between the two end cross beams 1132 along the first direction. The three inner cross beams 1131 divide the accommodating cavity 13 into two battery cell cavities 131 and a power distribution cavity 132. The power distribution cavity 132 is located at one end of the tray segment 11 in the first direction. Each battery cell cavity 131 is provided with a battery cell module 41.

[0042] Thus, by setting the inner crossbeam 1131, the limited space in the tray section is fully utilized, and the inner crossbeam 1131 can replace the crossbeam in the battery pack 4 in the prior art, reducing the weight of the frame assembly 100, which is beneficial to the integrated design of the frame assembly 100. Moreover, by dividing the accommodating cavity 13 into the battery cell cavity 131 and the distribution cavity 132, the battery cell module 41 and the distribution box 42 of the battery pack 4 are separated, which can reduce the interference between different components of the battery pack 4, improve the safety and reliability of the battery pack 4, and facilitate management and maintenance.

[0043] According to some embodiments of the present invention, there are multiple battery cell modules 41 , and the multiple battery cell modules 41 are arranged at intervals along the third direction, and a cooler 5 is provided between two adjacent battery cell modules 41 .

[0044] For example, in Figure 3 In the example, the number of battery cell modules 41 is 2, and the two battery cell modules 41 are spaced apart in the third direction, and the cooler 5 is arranged between two adjacent battery cell modules 41. While improving the storage capacity of the battery pack 4, there is no need to add an additional cooler 5 outside the battery pack 4, which not only improves the cruising range of the entire vehicle, but also reduces the cost.

[0045] In a specific implementation, an outer crossbeam 411 is provided in a battery cell module 41 away from the bottom plate 111 in the third direction to prevent the battery from expanding and ensure the working reliability of the battery pack 4 .

[0046] Alternatively, if Figure 3 and Figure 6 As shown, at least one of the third directions of the cooler 5 is provided with a heating film 6, and the heating film 6 is connected to the distribution box 42. The heating film 6 can use the electric energy of the battery pack 4 itself to heat the battery cell module 41, solving the problem of low charging and discharging efficiency of the battery pack 4 in a low temperature environment.

[0047] Alternatively, if Figure 3As shown, the tray segment 11 further includes a sealing cover 14, which is disposed above the two longitudinal beams 112 and connected to the longitudinal beams 112. Such a configuration ensures the stability of the internal environment of the accommodating cavity 13, which is conducive to the normal operation of the battery pack 4. The sealing cover 14 is connected to the longitudinal beams 112, further enhancing the overall structural strength of the tray segment 11.

[0048] In a specific implementation, the sealing cover 14 is roughly in the shape of a flat plate, a reinforcement shape (i.e., reinforcing ribs) is punched out on the sealing cover 14, and a sealing gasket is pasted on the side wall of the sealing cover 14 facing the bottom plate 111 to further ensure the sealing of the battery pack 4.

[0050] According to the vehicle of the embodiment of the present invention, by adopting the above-mentioned frame assembly 100, the difficulty of installing the vehicle is reduced, the weight of the entire vehicle is reduced, and lightweight design is facilitated.
