[0032] To assist those of ordinary skill in the art with the understanding of the subject matter claimed, a specific embodiment of the present application is described in detail below in conjunction with the accompanying drawings.
[0033] Figure 1 is a schematic view of one embodiment of a fuse block with which the present application is concerned. The fuse block includes a general housing. For ease of illustration, portions of the general housing are removed to reveal the interior of the fuse block.
[0034] Various fuses are distributed in the general housing 10. There is also a partial fuse box 12 in the general housing 10, which is disposed in one portion of the general housing 10. The partial fuse box 12 includes a sub-housing 14, which has an interior in which fuses are also distributed. A first portion of fuses 20 is disposed in the general housing 10 and outside the partial fuse box 12. A second portion of fuses 24 is disposed in the sub-housing 14 of the partial fuse box 12. The first portion of fuses 20 is not the second portion of fuses 24. The first portion of fuses 20 includes a number of fuses 22, which can be the same fuses or different fuses. The second portion of fuses 24 includes a number of fuses 26, which can also be the same fuses or different fuses.
[0035] The interior of the sub-housing 14 is divided into a plurality of cavities 16 for receiving each of the fuses 26 of the second portion of fuses 24. In the illustrated embodiment, and using three fuses, all of which are of the second portion of fuses, the cavities 16 are shown. In addition to the sub-housing 14, the partial fuse box 12 includes fasteners 18. Through the fasteners 18, the partial fuse box 12 is mounted in the general housing 10. In the illustrated embodiment, a snap is shown schematically as the fastener 18 for mounting the partial fuse box 12 in the general housing 10.
[0036] The fuse box in which the general housing 10 is located can be a battery fuse box, which is mounted in the vicinity of the battery. The partial fuse box in which the sub-housing 14 is located can be a trunk fuse box. In a conventional vehicle, the trunk fuse box is typically located in the trunk. The present application integrates the trunk fuse box into the battery fuse box, which is located in the front compartment. Those skilled in the art will appreciate that the fuse box or partial fuse box herein is not limited to the battery fuse box and the trunk fuse box, but can also be, for example, an integration of an engine fuse box and a trunk fuse box, or an integration of a fuse box for high voltage distribution and a fuse box for low voltage distribution. By integrating the trunk fuse box into the battery fuse box, the layout space in the trunk is saved, the routing of the wiring harness is simplified, and the need for parts for assembly is avoided.
[0037] Figure 2Figure 1 is an exploded view of one embodiment of the fuse box according to the present application. As shown, the total housing 10 includes a cover 28 and a base 30. The cover 28 and the base 30 are connected by snap structures 29 provided on opposite edges and staggered. In the illustrated embodiment, the first portion of fuses 20 includes six fuses, which are distributed in the base 30 and have different current carrying capacities. The fuses 22 of the first portion of fuses 20 are arranged in the base 30. These fuses are sheet fuses, which can carry large current and supply power to large electrical loads of the vehicle, such as air conditioner fan, EPS power system, etc. Each fuse has two connection ends 32 made of metal; one of the connection ends 32 is connected to a bus bar 34. The other connection end 32 is connected to a bolt 36. The fuse box also includes a positive battery clamp 38, which is also provided in the base 30. The current distributed to the fuse box is further distributed via the positive battery clamp 38, where a portion of the current flows to the bus bar 34 and the first portion of fuses 20 connected to the bus bar 34, and the other portion of the current will flow to the local fuse box 12, which will be further described below.
[0038] The local fuse box 12 is designed as a module, which is an integral component, not only having independent fuse arranging space, but also having separate input, output and fastening structure. In addition to the sub-housing 14 and the fastener 18, the local fuse box 12 also includes a current input end 40 and a wire harness collecting table 42. The fastener 18, the current input end 40 and the wire harness collecting table 42 are integrated with the sub-housing 14. In the illustrated embodiment, the current input end 40 is a sheet structure, in which a terminal (not shown, such as a bolt) is provided. As previously described, the portion of the current via the positive battery clamp 38 enters the cavities of the local fuse box 12 via the terminal. The wire harness collecting table 42 is a plate structure, which is used to arrange the wire harnesses for passing through the fuses of the second portion of fuses. These wire harnesses output from the fuses can be arranged on the wire harness collecting table 42 to facilitate subsequent wiring.
[0039] The fuses of the second portion of fuses are arranged in the cavities 16. In the illustrated embodiment, there are a total of seven cavities, which are numbered from 1 to 7. Not all of the cavities are provided with fuses. According to the calculation of the electrical loads of the vehicle, a proper number of fuses are arranged in the local fuse box. The fuses of the second portion of fuses can be plug-in fuses as shown, which supply power to small electrical loads of the vehicle, such as vehicle lights, wipers, seats, display screens, etc. In addition, the volumes of the cavities 16 can be designed to be different, as shown. The left four cavities 16 shown as F4-F7 have the same volume, and the volume of the right three cavities 16 shown as F1-F3 is smaller, so the left four cavities 16 receive smaller fuses. Figure 1 Figure 3
[0040] The assembly of the local fuse box to the general housing is a snap-on connection. In Figure 4 In the illustrated embodiment, the fastener 18 comprises two hooks 19; 19. It is conceivable that there are two snap-on receiving structures in the base of the general housing, each having a portion that deforms the hooks 19; 19, and a portion that allows the hooks 19; 19 to recover from the deformation, thus enabling the installation of the local fuse box 12 to the base.
[0041] In Figure 2 In the illustrated embodiment, the base of the general housing has a rectangular shape. It is conceivable that the shape of the base of the general housing is not limited to the illustrated embodiment, but can also be square, circular, etc. Regardless of the shape of the base of the general housing, the local fuse box, as a modular part with high integration, can be integrated into the general housing.
[0042] Returning to Figure 2 The one connection end 32 of each fuse in the first portion of fuses, which is connected to the busbar 34, has a connection post 44 that can partially cooperate with the corresponding portion of the busbar 34. In the illustrated embodiment, the connection end 32 of each fuse has two connection posts 44. It can be seen that the size of the connection posts 44 varies according to the load capacity, some of which are large and can pass a larger current, while some of which are small and can pass a smaller current. The size, i.e. diameter, of the connection posts 44 is designed to be able to carry the current passing through the fuse 22 where the connection end 32 is located. Since the connection posts 44 cooperate with the busbar 34, these connection posts 44 provide fixation for the fuses. On the other hand, the corresponding protrusions are formed on the busbar 34 to be in close contact with the connection posts 44, so that current can pass through to achieve electrical connection.
[0043] In one embodiment, the connection of the connection end 32 of the fuse 22 to the busbar 34 is achieved by a riveting process, i.e. under a certain pressure, the connection end 32 and the busbar 34 are deformed to form the connection post 44 and the protrusion. In addition, the riveting process does not require a rivet when implemented, further reducing manufacturing costs.
[0044] As Figure 5 As shown, the assembled cover 28 and base 30 have a plurality of barriers for waterproofing. Figure 5 A sectional view of the assembled fuse box. The cover 28 has a plurality of first barriers 48, which extend towards the interior of the general housing, and the configuration of the cover 28, especially the first barriers 48, is shown in bold lines in the figure. Correspondingly, it is also shown in the figure that the base 30 has a plurality of second barriers 52, which extend towards the interior of the general housing. When the cover 28 and the base 30 are assembled, the first barriers 48 and the second barriers 52 penetrate each other and are arranged in a staggered manner. This structure constitutes a maze, blocking external substances from entering the general housing. The present application can achieve the protection capability of IP6K9K.
[0045] As shown in Figure 6 The total housing has a plurality of rib structures 54, including rib structures 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h, which cooperate with each fuse 22 in the first portion fuse 20, and have different shapes among the rib structures 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h, which are outlined in dashed lines in the figure. By providing the rib structures 54 and each rib structure 54a, 54b, 54c, 54d, 54e, 54f, 54g, 54h having different shapes, uniqueness in assembly is provided, which can prevent misassembly, thereby improving assembly efficiency.
[0046] The application integrates a smaller fuse box into a larger fuse box. The larger fuse, i.e. the total fuse box, is arranged in any vehicle, and does not need to leave installation space for the smaller fuse box, i.e. the local fuse. The total fuse box can use any one of the above embodiments or various combinations, and the application provides a cost-reduced fuse box solution.
[0047] Although specific embodiments of the application have been shown and described in detail to illustrate the principles of the application, it will be understood that the application can be embodied otherwise without departing from such principles.
