[0031] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] The following description, with reference to the accompanying drawings, describes a safe box 100 according to an embodiment of this application.

[0033] like Figure 1 and Figure 7 As shown, the safe box 100 according to an embodiment of this application includes a box body 1 and a plurality of connectors 2.

[0034] Specifically, the fuse box 100 is used to connect to the battery, the box body 1 defines a receiving space 11, a plurality of connectors 2 are spaced apart from each other, one end of the connector 2 is located in the receiving space 11 and is used to supply power to at least one electrical appliance, and the other end extends out of the receiving space 11, and the plurality of connectors 2 are electrically connected to a plurality of terminals 200 respectively.

[0035] Understandably, the multiple terminals 200 on the positive terminal of the battery form multiple circuits with multiple connectors 2. When the battery and fuse box 100 are used in a vehicle, if a collision or other extreme situation causes some circuits to have abnormal power supply, the remaining circuits can provide stable power supply, which can provide power for opening the vehicle doors and illuminating the emergency indicator lights, thus solving a series of dangerous situations caused by abnormal power supply, such as the vehicle being unable to open doors, lower windows, or have its hazard lights not working after a collision.

[0036] For example, there are two terminals 200 and two connectors 2, namely the main connector 23 and the redundant connector 24, which form the main circuit and the redundant circuit with the battery, respectively. The redundant circuit is decoupled from the main circuit. The main circuit supplies power to the non-collision safety electrical appliances of the whole vehicle. The redundant circuit connects to components such as doors, windows and emergency indicator lights. When the vehicle is hit and malfunctions, a certain electrical appliance under the main circuit will short-circuit due to the collision and lower the battery voltage, continuously providing a stable voltage to the redundant terminal 200. The battery locks the charge inside and can isolate the abnormality of the main terminal 200. The battery can cut off the power supply to the terminal 200 of the main circuit. The battery can continuously provide a stable voltage to the redundant circuit, ensuring that important electrical appliances related to collision safety work normally, ensuring the normal operation of the vehicle's basic safety functions, increasing the stability of the redundant circuit, and increasing the probability of occupants escaping when the vehicle malfunctions.

[0037] The box body 1 can protect the connector 2 and prevent external impact from damaging the connector 2.

[0038] In this embodiment, connector 2 is a copper busbar. Connector 2 has good conductivity and can carry a larger current under the same cross-sectional area compared with other metals, thus reducing volume and resistance loss.

[0039] According to the embodiment of this application, the fuse box 100 is provided with a plurality of interconnected connectors 2 spaced apart from each other. One end of each connector 2 is located in the receiving space 11 and is used to supply power to at least one electrical appliance, while the other end extends out of the receiving space 11. The plurality of connectors 2 are electrically connected to a plurality of terminals 200 respectively. When the battery and fuse box 100 are used in a vehicle, if a collision or other extreme situation causes a partial circuit power supply abnormality, the remaining circuits can be stably powered. This can provide power for opening the vehicle doors and illuminating the emergency indicator lights, solving a series of dangerous situations caused by abnormal power supply, such as the vehicle being unable to open doors, unable to lower windows, and hazard lights not illuminating after a collision, thereby increasing the probability of occupants escaping when the vehicle malfunctions.

[0040] In some embodiments of this application, such as Figure 1 and Figure 7 As shown, the box body 1 is provided with multiple sets of connecting posts 12. Each connector 2 is connected to at least one set of connecting posts 12. Each set of connecting posts 12 includes a first connecting post 121 and a second connecting post 122 that are spaced apart from each other. The first connecting post 121 and the second connecting post 122 are connected by a conductive element, at least part of which is a fuse. The first connecting post 121 is connected to the connector 2, and the second connecting post 122 is suitable for connection with an electrical appliance.

[0041] When a vehicle malfunctions due to a collision, a short circuit in a component of the main circuit causes the battery voltage to drop, the fuse to blow, and the battery to lock its charge. The battery can isolate the abnormality of the main terminal 200 and cut off the power supply to the terminal 200 of the main circuit. The battery can continuously provide a stable voltage to the redundant circuit, ensuring that important electrical components related to collision safety work normally, ensuring the normal operation of the vehicle's basic safety functions, increasing the stability of the redundant circuit, and increasing the probability of occupants escaping when the vehicle malfunctions.

[0042] Furthermore, the first connecting post 121 and the second connecting post 122 are respectively connected to the connector 2 and the electrical appliance, which can avoid direct electrical connection between the connector 2 and the electrical appliance, and facilitate the installation of a fuse between the connector 2 and the electrical appliance, thereby increasing the reliability of the battery circuit.

[0043] In this embodiment, the fuse is a MIDI fuse or a MINI fuse.

[0044] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the box body 1 is provided with multiple limiting grooves 131, each limiting groove 131 is used to accommodate a set of connecting posts 12. The fuse box 100 also includes multiple wiring terminals, which are respectively located in multiple limiting grooves 131 and are electrically connected to multiple sets of connecting posts 12. The wiring terminals are suitable for connecting to electrical appliances and can separate multiple sets of connecting posts 12 to avoid bridging between different sets of connecting posts 12 and avoid short circuits.

[0045] The inner wall of the limiting groove 131 is provided with a limiting protrusion 132, and the terminal is provided with a relief groove. The limiting protrusion 132 passes through the relief groove and can limit the terminal to prevent the terminal from coming out of the limiting groove 131.

[0046] In this embodiment, the box body 1 is provided along the length direction of the box body 1 (e.g., Figure 1 Multiple partitions 13 arranged at intervals in the second direction shown above define limiting grooves 131, increasing the shortest straight-line air distance between the two sets of connecting columns 12 and improving the air insulation capability.

[0047] Meanwhile, when the fuse blows, an electric arc may be generated at the break point. The partition 13 can act as a physical barrier to limit the spread of the arc, preventing it from spreading to adjacent terminals or circuits; at the same time, it can accelerate the extinguishing of the arc, obstruct the arc path, and help it cool and extinguish more quickly.

[0048] In some embodiments of this application, such as Figure 1 and Figure 2As shown, at least one limiting groove 131 has a different setting of limiting protrusion 132. This results in different shapes of the limiting groove 131 and different positions of the clearance groove on the matching terminal block, allowing the terminal block to be installed into the corresponding limiting groove 131, thus increasing the assembly efficiency of the fuse box 100.

[0049] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the safe box 100 also includes a cover 3, which is detachably connected to the box body 1. The cover 3 and the box body 1 together define the receiving space 11. The cover 3 and the box body 1 can jointly protect the connector 2 and the connecting post 12, preventing damage to the connector 2 and the connecting post 12 from external impacts.

[0050] Meanwhile, the cover 3 is detachable from the body 1. When the circuit is broken, the cover 3 can be opened to check the condition of the connector 2 and the connecting post 12, which facilitates the maintenance of the vehicle's circuit.

[0051] In some embodiments of this application, such as Figure 3 As shown, the lid 3 is provided with reinforcing ribs 34, which are along the length of the lid 3 (e.g., ...). Figure 1 The second direction shown) and the width direction (as shown) Figure 1 The first direction shown) is arranged in multiple rows and columns to increase the strength of the lid 3 and increase its impact resistance.

[0052] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the box cover 3 includes a lower cover 31 and an upper cover 32. The lower cover 31 is detachably connected to the box body 1, and the lower cover 31 and the box body 1 together define the receiving space 11. The upper cover 32 is rotatably connected to the lower cover 31, and the upper cover 32 covers the part of the connector 2 that extends out of the receiving space 11.

[0053] The top cover 32 can protect the part of the connector 2 that extends into the receiving space 11, further protecting the connector 2, and can also accommodate the pole post 200, increasing the reliability of the pole post 200.

[0054] At the same time, the upper cover 32 and the lower cover 31 are rotatably connected, and the upper cover 32 and the lower cover 31 can be opened respectively to inspect the part of the connector 2 located in the receiving space 11 and the part extending out of the receiving space 11.

[0055] In this embodiment, the rotational connection method between the upper cover 32 and the lower cover 31 is not limited. For example, a rotational shaft is provided between the upper cover 32 and the lower cover 31; or as... Figure 3 As shown, a rotating part 33 is provided between the upper cover 32 and the lower cover 31. The thickness of the rotating part 33 is less than the thickness of the upper cover 32 and the lower cover 31. It is sufficient to allow for a rotatable connection between the upper cover 32 and the lower cover 31.

[0056] In this embodiment, as Figure 3 As shown, both the lower cover 31 and the box body 1 are provided with a snap-fit ​​part 35, and the lower cover 31 and the box body 1 are snap-fit ​​connected.

[0057] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the connector 2 includes a connecting body 21 and a limiting structure 22. One end of the connecting body 21 is disposed within the receiving space 11 and is used to supply power to at least one electrical appliance, while the other end extends out of the receiving space 11. Two limiting structures 22 are disposed at the end of the connecting body 21 that extends out of the receiving space 11, and are positioned along the width direction of the connecting body 21 (e.g., ...). Figure 1 (As shown in the second direction), two limiting structures 22 are located at both ends of the connecting body 21 in the width direction. The end faces of the two limiting structures 22 that are close to each other abut against the two end faces of the pole post 200 along the width direction of the connecting body 21. The limiting structures 22 can limit the connecting body 21 in the width direction, preventing the pole post 200 and the connector 2 from rotating relative to each other, and avoiding affecting the connection effect between the pole post 200 and the connector 2.

[0058] In some embodiments of this application, such as Figure 3 As shown, the upper cover 32 is provided with an inverted buckle 321, which is snapped into the end face of the limiting structure 22 away from the connecting body 21. The connection between the upper cover 32 and the limiting structure 22 is relatively simple and reliable.

[0059] Furthermore, such as Figure 3 As shown, the upper cover 32 is provided with a cover body 322 and a side plate 323, and an inverted buckle 321 is provided on the cover body 322.

[0060] In some embodiments of this application, the connecting body 21 includes a pole connecting portion 211 and a connecting post connecting portion 212. The pole connecting portion 211 is used for electrical connection with the connector 12, and the connecting post connecting portion 212 is used for electrical connection with the connecting post 12. The connecting post connecting portion 212 is located along the width direction of the connector 2 (e.g., ...). Figure 1 The pole post connection 211 extends along the length direction of the connector 2 (as shown in the second direction). Figure 1 Extending in the first direction shown, the limiting protrusion 132 is provided on the pole post connecting part 211 and extends along the length direction of the connector 2.

[0061] In some embodiments of this application, such as Figure 1 , Figure 4 and Figure 5As shown, the connector 2 is connected to the pole post 200 by fasteners. The pole post 200 may be provided with a first stud 201. The pole post connecting part 211 of the connector 2 is provided with a first through hole 2111. The first stud 201 passes through the first through hole 2111 and then passes through the first nut 4, so as to tightly connect the connector 2 and the pole post 200.

[0062] In some embodiments of this application, such as Figure 1 , Figure 2 and Figure 6 As shown, the connector 2 and the connecting post 12 are connected by fasteners. The first connecting post 121 can be a stud. The connecting post connecting part 212 of the connector 2 is provided with a second through hole 2121. The second stud passes through the second through hole 2121. At least one second nut 5 is sleeved on the second stud to tightly connect the connector 2 and the connecting post 12.

Multiple interconnected connectors 2 are provided, one end of which is located in the receiving space 11 and is used to supply power to at least one electrical appliance. The other end extends out of the receiving space 11. The multiple connectors 2 are electrically connected to multiple terminals 200 respectively. When the battery and fuse box 100 are used in the vehicle, if a collision or other extreme situation causes a partial circuit power supply abnormality, the remaining circuits can be stably powered. This can provide power for opening the vehicle doors and illuminating the emergency indicator lights, solving a series of dangerous situations caused by abnormal power supply, such as the vehicle being unable to open doors, lower windows, or have hazard lights not illuminating after a collision, and increasing the probability of occupants escaping when the vehicle malfunctions.
