Description

Technical Field

[0001] This application belongs to the field of fuse box structure and relates to a fuse box for engine compartment. Background Technology

[0002] With the rise of new energy vehicles, their proportion is increasing, and vehicle platforms are constantly being upgraded, leading to more and more functional requirements, but the space available for the entire vehicle is becoming increasingly limited. While ensuring the strength and safety performance of the vehicle, lightweighting will be the mainstream trend. Current status of fuse box technology in the engine compartment: 1. Existing standard fuse boxes are divided into battery fuse boxes, junction boxes, engine compartment fuse boxes, instrument panel fuse boxes, and aftermarket fuse boxes, etc.; 2. The number of fuse boxes required by the entire vehicle is relatively large, with many high-current circuits, resulting in higher demand for junction boxes and battery fuse boxes; 3. Separate junction boxes and battery fuse boxes require more space. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a cabin fuse box.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A fuse box for aircraft cabins, characterized in that it includes a main body, which integrates a fuse box structure and a junction box structure. The main body has a rectangular outer shell, and a fuse area is set at the upper part of the inner shell. The fuse area has multiple sets of dividing slots to accurately locate the fuses and relays. A positive terminal area is set on the outer side of one long side of the outer shell, and multiple studs are set in the positive terminal area. Each stud is connected to a MIDI fuse and connected to a busbar through the fuse. The studs are used to connect power supplies or cables.

[0006] Furthermore, the positive electrode area is provided with one M6 stud and four M5 studs. The M6 ​​stud is used to connect to the positive electrode, and the MEGA fuse of the M6 ​​stud is connected to the busbar through another M6 stud. The four M5 studs are respectively connected to single-hole MEGA fuses. The other end of the single-hole MEGA fuse is connected to the busbar through a rivet point. Each M6 stud or M5 stud is fixedly connected to a cable guide bracket, and the cable guide bracket is provided with fins to support the cable.

[0007] Furthermore, the upper end of the main housing is provided with multiple studs, which are bolted to the busbar in the positive electrode area.

[0008] Furthermore, the safety area is arranged in a horizontal and vertical array with multiple fuses and relays, specifically including 13 JCASE fuses, 48 ​​MICRO2 fuses, 1 V15 relay, 3 V16 relays, 11 V6 relays, 2 V11 relays, and 1 ES fuse.

[0009] Furthermore, the upper and lower ends of the main box are respectively limited and connected to the upper cover and the lower cover. The main box is provided with a wiring hole, and the main box at the wiring hole position is equipped with a insert. The upper cover, the lower cover and the insert can effectively seal the box and the wiring hole.

[0010] In addition, multiple sets of limit locks are spaced apart on the outer shell, and the limit locks cooperate with the limiting structure of the upper or lower cover respectively.

[0011] The advantages and positive effects of this utility model are:

[0012] 1. The fuse box in this application adopts a solution that integrates the junction box and the fuse box. Since the high-current circuits are all in the cabin environment, the junction box and the normal cabin fuse box are integrated together according to the requirements. By selecting mature materials to cope with the cabin environment, the power supply can be directly drawn from the integrated fuse box and the high-current circuit can be connected. This allows one integrated fuse box to meet the functional requirements of two products, solve existing problems at a lower cost, and meet the needs of the client.

[0013] 2. The integrated novel fuse box of this application is a fuse box with multiple functions, wide application, high development value, strong practicality, and high safety and reliability. Attached Figure Description

[0022] In this embodiment, the vertical direction, horizontal direction, front end, and rear end are all relative position descriptions and do not limit the actual orientation of the product.

[0023] A fuse box for engine compartments, see attached document. Figure 1 As shown, it includes a main box 2, which integrates a fuse box 7 and a junction box structure. The upper and lower ends of the main box 2 are respectively limited and connected to the upper cover 1 and the lower cover 3. The main box 2 is provided with a cable routing hole. The main box 2 at the cable routing hole position is equipped with a plug. The upper cover 1, the lower cover 3 and the plug can effectively seal the box and the cable routing hole, achieving an overall dustproof and waterproof rating of IP5K4K, which fully meets the requirements for waterproof and dustproof use in the cabin.

[0024] See appendix Figure 2 As shown, the main box 2 is provided with a rectangular outer shell 201. Multiple sets of limit locks 203 are provided on the outer shell 201 at intervals. The limit locks 203 cooperate with the limit structure of the upper cover 1 or the lower cover 3 respectively, so as to ensure the stable connection between the main box 2 and the upper cover 1 or the lower cover 3.

[0025] Multiple sets of dividing slots 202 are provided at the upper part of the inner casing 201. The dividing slots 202 facilitate accurate positioning of the fuses 7 and relays 8 to be installed. A positive area is set on the outer side of one long side of the casing 201. Multiple studs 5 are provided in the positive area. Each stud 5 is connected to a MIDI fuse 7 and connected to a busbar 9 through the fuse 7. The studs 5 are used to connect power or cables.

[0026] See appendix Figure 3The diagram shows the structure of the positive electrode area. In this embodiment, one M6 stud 5 and four M5 studs 5 are provided.
