[0033] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0035] In related technologies, components such as the rear-end controller and high- and low-voltage converters are placed in the trunk or under the seats. These components, along with their associated wiring harnesses, cannot be squeezed to prevent damage. This also takes up space in the trunk or under the seats, impacting the placement of components like the battery. This is especially true for certain models with demanding appearances, where space for these components is limited.

[0036] In view of this, if Figures 1 to 5 As shown, an embodiment of the present application provides a rear storage box arrangement structure, including a rear storage box 1, a first bracket 2, a rear domain controller 3, a battery assembly 4 and a high-low voltage converter 5. The rear storage box 1 has a first frame 11 facing the head of the vehicle and a second frame 12 opposite to the first frame 11. The first bracket 2 is connected to the first frame 11. In a specific implementation, the first bracket 2 is fixed to the first frame 11 by fasteners and the first bracket 2 is located above the first frame 11. The rear domain controller 3 and the battery assembly 4 are connected to the first bracket 2. The battery assembly 4 can be a 48V supercapacitor battery. The first bracket 2 is a rear trunk lid bracket.

[0037] like Figure 2As shown, the high and low voltage converter 5 is connected between the first bracket 2 and the second frame 12, and the high and low voltage converter 5 can be located directly above the rear storage box 1. Along the width direction of the vehicle, the rear domain controller 3, the high and low voltage converter 5 and the battery assembly 4 are spaced in sequence. There is enough storage space in the rear storage box 1 of the trunk. The rear domain controller 3, the high and low voltage converter 5 and the battery assembly 4 are arranged around the rear storage box 1, that is, in the trunk, and no longer occupy the space under the front trunk and the seat, which is suitable for more car models. Moreover, when the vehicle is collided or squeezed, the spaced rear domain controller 3, the high and low voltage converter 5 and the battery assembly 4 are staggered in the width direction of the vehicle, and are not easily squeezed to cause damage.

[0038] In some embodiments, a first mounting bracket 6 is disposed at the bottom of the high-low voltage converter 5. One end of the first mounting bracket 6 is detachably connected to the second frame 12, and the other end of the first mounting bracket 6 is plugged into the first bracket 2 and can move closer to or further away from the first bracket 2 to adapt to changes in the spacing between the first bracket 2 and the second frame 12. When the vehicle is squeezed in the longitudinal direction, the distance between the first frame 11 and the second frame 12 of the rear storage box 1 decreases when squeezed and returns to the original spacing after the squeezing ends. The other end of the first mounting bracket 6 is plugged into the first bracket 2 and can move closer to or further away from the first bracket 2, adapting to the spacing between the first frame 11 and the second frame 12. The rear storage box 1 will not be deformed when squeezed, thus avoiding damage or even malfunction, which would prevent the rear door from opening normally.

[0039] When implementing it specifically, Figure 4 and Figure 5 As shown, a first slot 24 and a second slot 25 are provided on the first bracket 2, and a first guide portion 61 and a second guide portion 62 are formed on one end of the first mounting frame 6 facing the first bracket 2. The first guide portion 61 is inserted into the first slot 24, and the second guide portion 62 is inserted into the second slot 25.

[0040] In some embodiments, as Figures 1 to 3 As shown, the rear storage box arrangement also includes a vehicle body wiring harness 7. A fixing structure 13 is provided on the inner wall of the rear storage box 1. The vehicle body wiring harness 7 is tensioned to one side of the inner wall of the rear storage box 1 via the fixing structure 13. The vehicle body wiring harness 7 is located below the high-low voltage converter 5. The vehicle body wiring harness 7 is located within the rear storage box 1 and can be in a tensioned state. Located below the high-low voltage converter 5, this prevents the vehicle body wiring harness 7 from being squeezed or bent. The vehicle body wiring harness 7 is used to connect the battery assembly 4 and the rear domain controller 3 to other vehicle components.

[0041] In some embodiments, as Figures 1 to 3As shown, a first connecting plate connected to the rear domain controller 3 and a second connecting plate connected to the battery assembly 4 are formed on the first bracket 2. The first connecting plate is connected to the rear domain controller 3 on one side surface facing the head of the vehicle, and the second connecting plate is connected to the battery assembly 4 on one side surface facing the rear of the vehicle.

[0042] That is to say, the rear domain controller 3 is located on the side of the first bracket 2 away from the rear storage box 1, the battery assembly 4 and the high and low voltage converter 5 are located on the side of the first bracket 2 facing the rear storage box 1, and the side of the first connecting plate facing the rear of the vehicle is just the cavity of the storage box. Figure 2 Area A shown here is free of metal parts or brackets that could impact or squeeze the rear domain controller 3 during a collision or crushing. The second connecting plate's rear-facing surface is connected to the battery assembly 4, which is located within or above the cavity of the rear storage box 1. This prevents collision or crushing with other components, thus protecting the battery assembly 4.

[0043] like Figure 3 and Figure 4 As shown, the wiring terminals of the rear domain controller 3 are connected to the wiring harness of the rear domain controller 3. The wiring harness of the rear domain controller 3 passes around the bottom of the first bracket 2 and is restrained on the side of the first connecting plate facing the rear of the vehicle. A first protective frame 21 is formed on the surface of the first connecting plate facing the rear of the vehicle. The first protective frame 21 is used to protect the wiring harness of the rear domain controller 3, which is connected to the body wiring harness 7. A second protective frame 22 is formed on the surface of the second connecting plate facing the rear of the vehicle. The second protective frame 22 surrounds the periphery of the connection between the battery assembly 4 and the first bracket 2.

[0044] In some embodiments, as Figure 3 and Figure 4 As shown, a third connecting plate is formed on the first bracket 2. The side of the third connecting plate facing the rear of the vehicle is connected to the high-low voltage converter 5. A third protective frame 23 is formed on the side of the third connecting plate facing the rear of the vehicle. The third protective frame 23 surrounds the periphery of the connection between the high-low voltage converter 5 and the first bracket 2. The third protective frame 23 protects the connection between the high-low voltage converter 5 and the first bracket 2 from being easily touched, preventing poor contact.

[0045] In some embodiments, as Figure 4 and Figure 5As shown, a first slot 24 is formed between the first protective frame 21 and the third protective frame 23, a second slot 25 is formed between the second protective frame 22 and the third protective frame 23, and a first mounting bracket 6 is configured at the bottom of the high and low voltage converter 5. The first mounting bracket 6 is formed with a first guide portion 61 and a second guide portion 62 on the side facing the first frame 11. The first guide portion 61 is plugged into the first slot 24, and the second guide portion 62 is plugged into the second slot 25.

[0046] Slots are formed between the first, second, and third protective frames 21, 22, and 23. First, when the vehicle is hit from the side, the spacing between the first, second, and third protective frames 21, 22, 23 cushions the impact energy, further preventing the rear domain controller 3, high- and low-voltage converter 5, and battery assembly 4 from being squeezed against each other. Second, the spacing between the third protective frame 23 and the first, second, and third protective frames 21, 22 forms the first and second slots 24, 25, allowing the first mounting bracket 6 to move closer to or further from the first bracket 2, thereby adapting to the spacing between the first and second frames 11, 12.

[0047] In some embodiments, as Figure 5 As shown, a groove 63 is formed on the first guide portion 61 and is recessed in the vehicle width direction. Alternatively, a groove 63 is formed on the second guide portion 62 and is recessed in the vehicle width direction. In this way, when the storage box 1 is squeezed and deformed after the vehicle is collided in its length direction, the first mounting bracket 6 can have a small length adjustment at one end facing the head of the vehicle to adapt to the change in the spacing between the first frame 11 and the second frame 12. Of course, a groove 63 is formed on the first guide portion 61 and is recessed in the vehicle width direction, and a groove 63 is formed on the second guide portion 62 and is recessed in the vehicle width direction. The end of the first mounting bracket 6 facing the head of the vehicle can adapt to the change in the spacing between the first frame 11 and the second frame 12.

[0048] In some embodiments, the battery assembly 4 is located above the rear storage box 1. This prevents the rear storage box 1 from squeezing the battery assembly 4 and potentially catching fire. A second mounting bracket 9 is located at the bottom of the battery assembly 4 and is connected to the first bracket 2. A right cover mounting bracket 10 is also located to the right of the battery assembly 4 and is connected to the vehicle body 8.

[0049] In some embodiments, along the width of the vehicle, the distance between the rear domain controller 3 and the high- and low-voltage converters 5 is D1, where D1 ≥ 20 mm. The distance between the battery assembly 4 and the high- and low-voltage converters 5 is D2, where D2 ≥ 20 mm. When D1 ≥ 20 mm and D2 ≥ 20 mm, the rear domain controller 3, the high- and low-voltage converters 5, and the battery assembly 4 will not come into contact during a side collision, preventing them from being squeezed.

[0050] Another embodiment of the present application provides a vehicle, such as Figure 1 As shown, the vehicle includes a body part 8 and the above-mentioned rear storage box arrangement structure, and the rear storage box 1 is connected to the body part 8. It saves space in the vehicle's front trunk and the bottom side of the seat, and is suitable for the arrangement of more models.
