In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0039] Next, the embodiments of this specification are described in detail.

[0040] Reference Figure 1-4 As shown, the present application discloses a fuse relay box assembly, which includes an upper cover 10, a lower cover 20, a fuse module 30, a relay module 40, and a mounting bracket 50. The upper cover 10 and the lower cover 20 form a receiving cavity 11, and the fuse module 30 and the relay module 40 are accommodated in the receiving cavity 11.

[0041] The upper cover 10 has a snap 12 on its side, and a corresponding bump 22 on the side of the lower cover 20 that mates with the snap 12. The snap 12 and bump 22 engage to secure the upper cover 10. Furthermore, a groove 13 is provided at one end where the upper cover 10 connects to the lower cover 20, and a ridge 23 is provided on the lower cover 20 that mates with the groove 13. An electronically injected rubber ring is installed at the junction of the groove 13 and the ridge 23 for sealing.

[0042] The lower cover 20 is provided with a cover clamping portion 21 , and the mounting bracket 50 is provided with a bracket clamping portion 51 and a component mounting portion 52 . The cover clamping portion 21 and the bracket clamping portion 51 are buckled with each other to achieve a movable connection between the lower cover 20 and the mounting bracket 50 .

[0043] The mounting bracket 50 includes a first bracket 50a and a second bracket 50b, each of which is provided with a bracket clamping portion 51 and a component mounting portion 52. The bracket clamping portion 51 is disposed against the side of the lower cover 20, and the component mounting portion 52 is disposed away from the lower cover 20.

[0044] The first bracket 50a and the second bracket 50b are respectively disposed on either side of the lower cover 20. The bracket engaging portion 51 of the first bracket 50a is perpendicular to the assembly mounting portion 52, while the bracket engaging portion 51 of the second bracket 50b is parallel to the assembly mounting portion 52. The bracket engaging portion 51 and the assembly mounting portion 52 are connected by an intermediate plate 53. The positional relationship between the bracket engaging portion 51 and the assembly mounting portion 52 can be adjusted to suit different vehicle models and installation environments. Alternatively, a single bracket or multiple brackets can be provided, depending on the vehicle model and installation environment in which the fuse relay box assembly will be installed.

[0045] The assembly mounting portion 52 includes at least two bolt mounting holes 521 , the spacing between the two bolt mounting holes 521 is close to the length of the side of the lower cover 20 , and the bolt mounting holes 521 on the first bracket 50 a and the bolt mounting holes 521 on the second bracket 50 b are arranged perpendicularly.

[0046] The cover engaging portion 21 includes a slot 211 provided on the side of the lower cover 20 and a latch block 212 positioned within the slot 211. The bracket engaging portion 51 includes an insert 511 and a latch notch 512 formed on the insert 511. When the insert 511 is inserted into the slot 211, the latch block 212 engages with the latch notch 512, and the first bracket 50a and the second bracket 50b are locked to the fuse relay box assembly via the bracket engaging portion 51.

[0047] In order to facilitate the later removal of the first bracket 50a and the second bracket 50b, the insert 511 is formed with a protrusion 513 above the bayonet 512. The protrusion 513 is located above the block 212 so that the protrusion 513 and the side of the lower cover 20 form a space for accommodating disassembly tools.

[0048] Reference Figure 5-6 As shown, the fuse-relay box assembly further includes a module base 60, which is snap-fitted into the lower cover 20. The module base 60 defines a plurality of accommodating cavities 61, into which the fuse module 30 and the relay module 40 are snap-fitted. Specifically, the outer walls of the fuse module 30 and the relay module 40 are provided with engaging portions 31, and the inner walls of the corresponding accommodating cavities 61 are provided with snap-fitting seats 62 for engaging the engaging portions 31.

[0049] Reference Figure 7-8 As shown, the four corners of the bottom of the lower cover 20 are respectively provided with a water leakage structure, which includes two water leakage holes 71 and 72. The two water leakage holes 71 and 72 are interconnected and staggered in the vertical direction.

[0050] Reference Figure 1As shown, the lower cover 20 is also provided with a waterproof rubber ring 80 for the cable to pass through, and the waterproof rubber ring 80 is snap-fitted to the lower cover 20. Specifically, an annular positioning ridge 24 is formed on the lower cover 20 through a glue injection process, and an annular positioning groove 81 is provided on the outer wall of the waterproof rubber ring 80 to match the annular positioning ridge 24. The snap-fitting of the annular positioning ridge 24 and the annular positioning groove 81 realizes the connection between the waterproof rubber ring 80 and the lower cover 20.

[0051] For different vehicle models or installation environments, only the mounting bracket 50 needs to be developed. After the mounting bracket 50 is snapped into the fuse relay box assembly, the mounting bracket 50 is fixed to the vehicle by bolts to match the surrounding environment, and has strong compatibility.

[0052] By adopting modular assembly of fuse and relay structures, this application can combine different quantities as needed, thereby meeting the adjustment of functional development requirements of various vehicle models and avoiding the cost of new installations. In addition, in addition to being fixed by the buckle 12, the upper cover 10 and the lower cover 20 are also provided with an electronic injection rubber ring at the joint for sealing, which improves the efficiency of automated production and the reliability of sealing. In addition, the two leakage holes 71 and 72 arranged in a staggered manner make the leakage structure more reliable in waterproofing and dustproofing, ensuring that there is no water accumulation in the receiving chamber 11 while avoiding direct impact of external pollutants such as water vapor and dust.

[0053] The present application also discloses a vehicle, comprising a frame rail and the aforementioned fuse relay box assembly, wherein the fuse relay box assembly is mounted on the frame rail via an assembly mounting portion 52 on a mounting bracket 50. The assembly mounting portion 52 is provided with two bolt mounting holes 521, so that the assembly mounting portion 52 and the frame rail can be fixedly connected by bolts.
