Detailed Implementation Methods

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0021] Examples of this application: Figure 1 and Figure 2 As shown, a modular automotive fuse box includes a fuse box body 1. The fuse box body 1 has several secondary fuse mounting holes, tertiary fuse mounting holes, and relay mounting holes. Secondary fuses are plugged into the secondary fuse mounting holes, tertiary fuses are plugged into the tertiary fuse mounting holes, and relays 37 are plugged into the relay mounting holes. Multiple primary fuse units are provided on the outer wall of one side of the fuse box body 1. All primary fuse units are connected via guide plates 2. A first busbar 3 and a second busbar 4 are installed inside the fuse box body 1. The first busbar 3, the second busbar 4, and the guide plates 2 are connected via positive studs 5.

[0022] The number and arrangement of the secondary fuse mounting holes, tertiary fuse mounting holes, and relay mounting holes within the fuse box body 1 are set according to actual needs. The specific structures of the secondary fuse mounting holes, tertiary fuse mounting holes, and relay mounting holes can adopt existing designs. This application does not improve the structure of the secondary fuse mounting holes, tertiary fuse mounting holes, and relay mounting holes, and they are not protected by this application. Therefore, this application will not elaborate on their specific structures.

[0023] The fuse box body 1 has a rectangular parallelepiped structure. For ease of description, the side wall where the primary fuse unit is located is called the front side wall, the side wall opposite the front side wall is called the rear side wall, the side wall to the left of the front side wall is called the left side wall, and the side wall to the right of the front side wall is called the right side wall. The primary fuse unit is located on the front side wall and does not occupy the internal lateral space of the fuse box body 1. This allows the primary, secondary, and tertiary fuses and relay 37 to be housed on the same fuse box body 1 while effectively controlling the volume of the fuse box body 1, making the fuse box easy to arrange.

[0024] The lower part of the first busbar 3 is a long strip structure, and the top of the long strip structure has several tuning forks 6. One end of the first busbar 3 has a first mounting plate 7, and the first mounting plate 7 has a first mounting hole 8. The first mounting plate 7 is parallel to the top surface of the fuse box body 1, and the first mounting plate 7 is mounted on the positive stud 5 through the first mounting hole 8.

[0025] The positive stud 5 is installed inside the fuse box body 1 near the front and left side walls. In this embodiment, the first busbar 3 has a 90° bend, so that after the first busbar 3 is connected to the positive stud 5, it first extends towards the rear side wall, and then extends towards the right side wall after passing through the bend. Each triple fuse mounting hole has a tuning fork 6. When the triple fuse is inserted into the triple fuse mounting hole from top to bottom, the electrode at one end of the triple fuse is connected to the tuning fork 6 and held by the tuning fork 6.

[0026] The lower part of the second busbar 4 is also a long strip structure. The top of the long strip structure has several rectangular power supply pins 9. The second busbar 4 is parallel to the front side wall. The left end of the second busbar 4 is bent at 90° and extends towards the front side wall. The top of this end has a second mounting plate 10. The second mounting plate 10 has a second mounting hole 11. The second mounting plate 10 is parallel to the top surface of the fuse box body 1. The second mounting plate 10 is mounted on the positive stud 5 through the second mounting hole 11. The right end of the second busbar 4 is bent at 90° and extends towards the rear side wall. The top of this end has a relay standard socket 42.

[0027] Each secondary fuse mounting hole has a rectangular power supply pin 9. When the secondary fuse is inserted into the secondary fuse mounting hole from top to bottom, one of the holes at the bottom of the secondary fuse is connected to the rectangular power supply pin 9.

[0028] It should be noted that the main difference between Level 1, Level 2, and Level 3 fuses lies in their melting heat values. In this embodiment, Level 1 fuses use MIDI fuses from the prior art, Level 2 fuses use J-CASE slow-melting fuses from the prior art, and Level 3 fuses use MINI fuses from the prior art.

[0029] A standard relay socket 42 is provided on the second busbar 4, which can directly connect a POWER MINI relay. The 30 terminal of the POWER MINI relay is directly supplied with constant power by the second busbar, which can save the installation process of the wire harness terminal of the high current relay 30 terminal and a fuse, and greatly reduce the risk of thermal failure of the relay 30 terminal due to terminal contact.

[0030] Furthermore, the guide plate 2 is provided with multiple third mounting holes 12, the number of which is the same as the number of primary safety units. The top of the guide plate 2 is folded 90° to form a horizontal limiting surface 13. The horizontal limiting surface 13 has a third mounting plate 14, and the third mounting plate 14 is provided with a fourth mounting hole 15. The third mounting plate 14 is mounted on the positive electrode stud 5 through the fourth mounting hole 15.

[0031] In this embodiment, five primary safety units are preferably provided, and correspondingly, five third mounting holes 12 are provided on the guide plate 2. After the guide plate 2 is connected to the five primary safety units, it is attached to the outer wall of the front side wall of the fuse box body 1. At the same time, the horizontal limiting surface 13 on the guide plate 2 is attached to the top surface of the fuse box body 1. The positive stud 5 passes through the fourth mounting hole 15 and plays a positioning role for the guide plate 2.

[0032] In this embodiment, a positive electrode stud mounting hole (not shown in the figure) is provided inside the fuse box body 1. After the first busbar 3, the second busbar 4, and the guide plate 2 are all installed in place, the first mounting plate 7 on the first busbar 3, the second mounting plate 10 on the second busbar 4, and the third mounting plate 14 on the guide plate 2 are stacked together in the longitudinal direction. The first mounting hole 8, the second mounting hole 11, and the fourth mounting hole 15 are all coaxial with the positive electrode stud mounting hole. The positive electrode stud 5 is installed on the stud mounting base 39. The positive electrode stud 5 and the stud mounting base 39 are inserted into the positive electrode stud mounting hole from the bottom of the fuse box body 1 from bottom to top. The stud mounting base 39 and the positive electrode stud mounting hole are connected by a snap-fit. The positive electrode stud 5 passes through the first mounting hole 8, the second mounting hole 11, and the fourth mounting hole 15.

[0033] Then, a DC-DC input terminal 24 is installed on the positive stud 5. The upper end of the DC-DC input terminal 24 is folded 90° to form a mounting part 23. A fifth mounting hole is provided on the mounting part 23, and the mounting part 23 is installed on the positive stud 5 through the fifth mounting hole. The DC-DC input terminal 24 is also located on the outer wall of the front side wall of the fuse box body 1. A DC-DC input nut 35 is installed on the positive stud 5. The DC-DC input nut 35 is used to press the mounting part 23 against the first mounting plate 7, the second mounting plate 10, and the third mounting plate 14. DC power is transmitted through the mounting part 23 to the first mounting plate 7, the second mounting plate 10, and the third mounting plate 14, and then through the first busbar 3, the second busbar 4, and the guide plate 2 to the third-level fuse, the second-level fuse, the relay 37, and the first-level fuse.

[0034] The positive stud 5 is designed to be detachable, which not only facilitates assembly, but also makes it easy to repair and replace if the positive stud 5 is damaged.

[0035] Specifically, the primary fuse unit includes a first mounting stud 16, a MIDI fuse 17, a second mounting stud 18, and a power distribution terminal 19. The first mounting stud 16 and the second mounting stud 18 are fixed to the side wall of the fuse box body 1. The second mounting stud 18 is located directly below the first mounting stud 16. One end of the MIDI fuse 17 is mounted on the first mounting stud 16, and the other end of the MIDI fuse 17 is mounted on the second mounting stud 18. The upper end of the power distribution terminal 19 is mounted on the second mounting stud 18. Both the first mounting stud 16 and the second mounting stud 18 are equipped with projection-welded nuts 32.

[0036] The first mounting stud 16 and the second mounting stud 18 are vertically distributed, therefore the MIDI fuse 17 is also vertically mounted. The guide plate 2 is connected to the first mounting stud 16 through the third mounting hole 12. DC power is transmitted through the guide plate 2 to the upper end of the MIDI fuse 17, and then from the lower end to the power distribution terminal 19. Preferably, each first mounting stud 16 and each second mounting stud 18 is fitted with an anti-loosening nylon ring 40, which cooperates with the projection weld nut 32 to prevent loosening.

[0037] Preferably, two adjacent primary fuse units are separated by a longitudinally arranged insulating partition 20. The insulating partition 20 serves as a barrier to prevent wires on adjacent power distribution terminals 19 from bridging, and also protects the MIDI fuse 17.

[0038] In addition, insulating partitions 20 are provided on both sides of the DC-DC input terminal 24. These two insulating partitions 20 constitute the DC-DC positive input channel 41.

[0039] The fuse box body 1 has at least one movable insert mounting slot 21. A relay movable insert 22 is detachably installed in the movable insert mounting slot 21, and the relay movable insert 22 is snap-fitted into the movable insert mounting slot 21. The snap-fit ​​structure can adopt a conventional snap-fit ​​method.

[0040] A detachable relay insert 22 is installed inside the fuse box body 1. The relay insert 22 can accommodate three types of relays: POWER MINI, MINI, and MICRO, allowing for various combinations and flexibility to meet different electrical configuration requirements. If the vehicle's electrical configuration is low, the relay insert 22 may not be installed, thus reducing the overall manufacturing cost of the fuse box. This application preferably uses two relay inserts 22.

[0041] Furthermore, this application also includes a fuse box cover 25, a locking tongue 26 is provided on the outer wall of the left side and the right side of the fuse box body 1, a hook 27 is provided on the fuse box cover 25 to engage with the locking tongue 26, and a primary fuse unit protective plate 28 is formed on one side of the fuse box body 1.

[0042] Since the fuse box cover 25 needs to be easy to open and secure for maintenance and fault inspection, it uses two hooks 27 to engage with the fuse box body 1.

[0043] After the fuse box cover 25 is installed onto the fuse box body 1, the primary fuse unit protective plate 28 covers the primary fuse unit and the DC-DC positive input channel 41, thus providing waterproofing and preventing water from splashing onto the primary fuse and the DC-DC input terminal 24. Furthermore, the MIDI fuse 17 and the DC-DC input terminal 24 are both arranged vertically, allowing for rapid drainage even if a small amount of water enters from the bottom.

[0044] The fuse box cover 25 of this application is provided with a chip puller 33 and multiple spare fuses 34. The chip puller 33 and the spare fuses 34 are fixed on the fuse box cover 25 in a conventional way. The chip puller 33 and the spare fuses 34 are also existing technologies. The specific structure of them will not be described in detail in this embodiment.

[0045] Since the fuse box cover 29 does not require frequent disassembly, the fuse box body 1 of this application has four side walls equipped with locking blocks 30, and the side walls of the fuse box cover 29 are equipped with locking plates 31 that engage with the locking blocks 30. Through the engagement of multiple locking blocks 30 and locking plates 31, the fuse box cover 29 is less likely to detach from the fuse box body 1, improving product reliability. The bottom of the fuse box cover 29 is equipped with a fuse box mounting buckle 38, which allows for quick fixing and positioning of the bottom of the fuse box cover 29. In addition, two fixing brackets 36 are installed on the rear side wall of the fuse box body 1 to facilitate fixing the fuse box to the vehicle body.

[0046] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this application. The above description is only a preferred embodiment of this application, but this application does not limit the scope of implementation to what is shown in the drawings. Any changes made in accordance with the concept of this application, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, should be within the protection scope of this application.
