[0071] The embodiments of the present invention are used together with the description to explain the principles of the present invention. DETAILED DESCRIPTION

[0072] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0073] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0074] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0075] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0076] It should be noted that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described based on the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should be understood that when it is mentioned that an element is connected to another element "on" or "under", it can not only be directly connected to the other element "on" or "under", but also be indirectly connected to the other element "on" or "under" through an intermediate element.

[0077] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a car fuse box, including a main body 100, an upper cover 200 and a lower cover 300. The upper cover 200 is buckled on the top of the main body 100, and the lower cover 300 is provided with a receiving groove 301. At least part of the main body 100 is received in the receiving groove 301. The upper cover 200 is used to seal the main body 100, and the lower cover 300 is used to install and fix the car fuse box on the car body.

[0078] The structure of the main body 100 is first introduced below. Figure 3 As shown, the main body 100 is provided with a first mounting slot 101, a second mounting slot 102, and a third mounting slot 103. The first mounting slot 101 is installed with a first mounting module 1, and the second mounting slot 102 is installed with a second mounting module 2. The automobile fuse box also includes a relay 3, a slow-blow fuse 4, and an intelligent module 5. The relay 3 is installed in the first mounting module 1, the slow-blow fuse 4 is installed in the second mounting module 2, and the intelligent module 5 is installed in the third mounting slot 103.

[0079] Among them, the relay 3 is used to electrically connect to the high-current load in the car body to control the high-current load, and the slow-blow fuse 4 is used to electrically connect to the high-current load in the car body to provide power supply protection for the high-current load. This embodiment adopts a solution combining the relay 3 and the slow-blow fuse 4 to replace the solution of the driver chip and MOSFET (metal-oxide semiconductor field-effect transistor) in the prior art, which can reduce the cost of the fuse box. The intelligent module 5 is internally provided with an HSD chip (High Side Driver), that is, the intelligent module 5 adopts an HSD intelligent high-side switch integrated solution, which is used to electrically connect to the low-current load in the car body and has functions such as diagnosis, thermal protection, current detection, and voltage protection. The car fuse box provided by this application can replace some fuses and relays for low-current loads by providing the intelligent module 5, simplifying the internal structure of the car fuse box, which is conducive to reducing the volume of the intelligent fuse box and reducing the manufacturing cost of the intelligent fuse box. In addition, the intelligent module 5 can achieve a maintenance-free effect, which is conducive to reducing the maintenance cost of the intelligent fuse box.

[0080] Furthermore, the automobile fuse box provided in the present application is provided with a first mounting module 1 for mounting a relay 3. The number of relays 3 can be one or more. When there are multiple relays 3, it is only necessary to change the internal structure of the first mounting module 1 so that the multiple relays 3 can be arranged in the first mounting module 1. Similarly, the automobile fuse box is also provided with a second mounting module 2 for mounting a slow-blow fuse 4. The number of slow-blow fuses 4 can be one or more. When there are multiple slow-blow fuses 4, it is only necessary to change the internal structure of the second mounting module 2 so that the multiple slow-blow fuses 4 can be arranged in the second mounting module 2. That is, by providing the first mounting module 1 and the second mounting module 2, modularization of the relay 3 and the slow-blow fuse 4 can be achieved. When the automobile fuse box is used on different vehicle models, the internal structures of the first mounting module 1 and the second mounting module 2 can be adjusted according to the number of relays 3 or slow-blow fuses 4 required by each vehicle model without changing the external structures and dimensions of the first mounting module 1 and the second mounting module 2, thereby improving the versatility of the automobile fuse box.

[0081] In a specific embodiment, Figure 4 and Figure 5 As shown, the side wall of the first installation groove 101 is provided with a first limiting portion 101a, and the first installation module 1 is provided with a first matching portion 12. The first matching portion 12 cooperates with the first limiting portion 101a to limit the movement of the first installation module 1 along the depth direction Z of the first installation groove 101. And / or, as Figure 4 and Figure 6 As shown, the side wall of the second installation slot 102 is provided with a second limiting portion 102a, and the second installation module 2 is provided with a second matching portion 22, which cooperates with the second limiting portion 102a to limit the movement of the second installation module 2 along the depth direction Z of the second installation slot 102.

[0082] In this embodiment, the first matching portion 12 cooperates with the first limiting portion 101a to limit the movement of the first mounting module 1 along the depth direction Z of the first mounting groove 101, which can improve the installation stability of the first mounting module 1 and reduce the risk of the first mounting module 1 being separated from the first mounting groove 101, thereby facilitating the improvement of the installation stability of the relay 3. Specifically, one of the first matching portion 12 and the first limiting portion 101a can be a buckle, and the other can be a slot. Alternatively, as Figure 4 and Figure 5As shown, the first limiting portion 101a is a first protrusion, and the side wall of the first mounting module 1 can be provided with a first elastic portion 13. The first matching portion 12 is a second protrusion provided on the first elastic portion 13. During the process of placing the first mounting module 1 into the first mounting groove 101, the first elastic portion 13 can remain in an inwardly compressed state. When the second protrusion passes over the first protrusion and continues to move downward, the first elastic portion 13 completes the reset. In this way, when the first mounting module 1 is installed in place, the first protrusion can be matched with the second protrusion along the depth direction Z of the first mounting groove 101 to limit the movement of the first mounting module 1 along the depth direction Z of the first mounting groove 101.

[0083] Similarly, the second matching portion 22 cooperates with the second limiting portion 102a to limit the movement of the second installation module 2 along the depth direction Z of the second installation slot 102, which can improve the installation stability of the second installation module 2 and reduce the risk of the second installation module 2 being separated from the second installation slot 102, thereby facilitating the improvement of the installation stability of the slow-blow fuse 4. Specifically, one of the second matching portion 22 and the second limiting portion 102a can be a buckle, and the other can be a slot. Alternatively, as Figure 4 and Figure 6 As shown, the second limiting portion 102a is a third protrusion, and the side wall of the second mounting module 2 can be provided with a second elastic portion 23. The second matching portion 22 is a fourth protrusion provided on the second elastic portion 23. During the process of placing the second mounting module 2 into the second mounting groove 102, the second elastic portion 23 can remain in an inwardly compressed state. When the fourth protrusion passes over the third protrusion and continues to move downward, the second elastic portion 23 completes the reset. In this way, when the second mounting module 2 is installed in place, the third protrusion can cooperate with the fourth protrusion along the depth direction Z of the second mounting groove 102 to limit the first mounting module 1 from moving along the depth direction Z of the first mounting groove 101.

[0084] When the side wall of the first installation groove 101 is provided with a first limiting portion 101a and the first installation module 1 is provided with a first matching portion 12; and the side wall of the second installation groove 102 is provided with a second limiting portion 102a and the second installation module 2 is provided with a second matching portion 22, the installation stability of the first installation module 1 and the second installation module 2 can be simultaneously improved.

[0085] In a specific embodiment, Figure 5 and Figure 7 As shown, the relay 3 is provided with a first connection end 31, the first installation module 1 is provided with a first slot 11, the first connection end 31 is fixed in the first slot 11 and forms an electrical connection with the first slot 11. And / or, as Figure 6 and Figure 8As shown, the slow-blow fuse 4 is provided with a second connection end 41 , the second installation module 2 is provided with a second slot 21 , and the second connection end 41 is fixed in the second slot 21 and forms an electrical connection with the second slot 21 .

[0086] In this embodiment, the first connection end 31 is fixedly engaged with the first slot 11, which not only secures the relay 3 to the first mounting module 1, improving the installation stability of the relay 3 and reducing the risk of the relay 3 becoming detached from the first mounting module 1, but also electrically connects the relay 3 to the first mounting module 1, allowing the first mounting module 1 to supply power to the relay 3. Similarly, the second connection end 41 is fixedly engaged with the second slot 21, which not only secures the slow-blow fuse 4 to the second mounting module 2, improving the installation stability of the slow-blow fuse 4 and reducing the risk of the slow-blow fuse 4 becoming detached from the second mounting module 2, but also electrically connects the slow-blow fuse 4 to the second mounting module 2, allowing the second mounting module 2 to supply power to the slow-blow fuse 4.

[0087] In a specific embodiment, Figure 4 and Figure 9 As shown, the automobile fuse box further comprises a fuse piece 6 and a bus bar 7 mounted on the side wall of the main body 100 , and the bus bar 7 is electrically connected to the external power supply and the fuse piece 6 respectively.

[0088] In this embodiment, if Figure 9 As shown, busbar 7 is an L-shaped structure, comprising a first portion 71 and a second portion 72, which are fixedly connected. First portion 71 is connected to an external power source via a power inlet bolt 73, which also secures first portion 71 to main body 100. Second portion 72 is electrically connected to fuse plate 6 via a first fastening bolt 61 and a first fastening nut 62, enabling busbar 7 to supply power to fuse plate 6. The first fastening bolt 61 and the first fastening nut 62 also simplify the connection structure. Furthermore, busbar 7 is electrically connected to first mounting module 1, second mounting module 2, and smart module 5, respectively, thereby supplying power to these modules. This embodiment utilizes a sheet-like busbar 7 to achieve power distribution, reducing the size of the vehicle fuse box, thereby reducing the space it occupies and lowering the manufacturing cost of the vehicle fuse box.

[0089] like Figure 9 As shown, the end of the fuse piece 6 away from the bus bar 7 can be electrically connected to the high current load in the vehicle body through the second fastening bolt 63 and the second fastening nut 64, which simplifies the connection structure. Figure 9As shown, the number of safety pieces 6 can be one or more. When the number of safety pieces 6 is multiple, they can be arranged side by side. Moreover, a crimping structure 106 can be provided on the side wall of the main body 100 to ensure installation stability. The safety piece 6 is pressed into the crimping structure by the first fastening bolt 61 and the first fastening nut 62, the second fastening bolt 63 and the second fastening nut 64, thereby facilitating the improvement of the installation reliability of the safety piece 6.

[0090] In addition, the fuse 6 can select a fuse capacity suitable for the specific conditions of the load to provide protection for the load circuit, which is not limited in this embodiment.

[0091] In a specific embodiment, Figure 4 As shown, a water retaining groove 105 is provided on the top of the main body 100 , and the water retaining groove 105 is distributed along the circumference of the main body 100 .

[0092] In this embodiment, the water retaining groove 105 has the functions of retaining and storing water, and can prevent external water from entering the interior of the main body 100 through the gap between the main body 100 and the upper cover 200, thereby improving the waterproof effect of the main body 100.

[0093] The specific structure of the upper cover 200 is introduced below. Figure 10 As shown, the upper cover 200 is provided with a fixedly connected convex portion 201 and a vertical extension portion 202. The convex portion 201 is distributed along the circumference of the upper cover 200. The size of the convex portion 201 is larger than that of the main body 100. When the upper cover 200 is buckled onto the main body 100, the convex portion 201 can provide a waterproof effect in the circumferential direction of the upper cover 200, preventing external water from entering the interior of the main body 100. The vertical extension portion 202 extends along the height direction of the upper cover 200 toward the main body 100. The vertical extension portion 202 can block the bus bar 7 and the fuse plate 6, providing a waterproof effect. At the same time, the vertical extension portion 202 can also divert the accumulated water in the convex portion 201 downward, thus playing a water-guiding role.

[0094] like Figure 4 and Figure 10 As shown, multiple locking mechanisms 203 are provided on the sidewalls of the upper cover 200 at intervals along the circumference of the upper cover 200; and multiple locking and mating mechanisms 107 are provided on the sidewalls of the main body 100 at intervals along the circumference of the upper cover 200. When the upper cover 200 is fastened to the main body 100, the multiple locking and mating mechanisms 107 correspond one-to-one with the multiple locking mechanisms 203 and interlock with each other, thereby restricting the relative movement of the main body 100 and the upper cover 200 along the axial direction Z of the automobile fuse box, thereby improving the connection reliability and sealing performance of the upper cover 200 and the main body 100. Specifically, the locking mechanisms 203 and the locking and mating mechanisms 107 can be snap-fit ​​structures, lock-fit structures, or magnetic structures, etc., which are not limited in this embodiment.

[0095] The specific structure of the lower cover 300 is introduced below. Figure 4 and Figure 11 As shown, multiple third limiting portions 304 are provided on the sidewalls of the lower cover 300 at intervals along the circumference of the lower cover 300; and multiple third mating portions 104 are provided on the sidewalls of the main body 100 at intervals along the circumference of the main body 100. When the main body 100 is placed in the receiving groove 301, the multiple third mating portions 104 correspond one-to-one with the multiple third limiting portions 304 and form a limited fit, thereby limiting the movement of the main body 100 along the depth direction Z of the receiving groove 301, thereby improving the connection reliability and sealing between the lower cover 300 and the main body 100. Specifically, the third limiting portions 304 and the third mating portions 104 can adopt a snap-fit ​​structure, a lock-fit structure, or a magnetic fit structure, etc., which is not limited in this embodiment.

[0096] In addition, if Figure 12 As shown, the bottom wall of the lower cover 300 is provided with a plurality of spaced-apart water guide holes 302, forming a louver structure. This is used to drain water trapped between the main body 100 and the lower cover 300 to the outside, preventing water from accumulating inside the vehicle fuse box. Furthermore, the water guide holes 302 can be strip-shaped, which helps to increase water drainage capacity and improve drainage efficiency.

[0097] In a specific embodiment, Figure 4 As shown, multiple bracket mounting portions 303 are spaced apart along the circumference of the automobile fuse box on the sidewalls of the lower cover 300 and / or the sidewalls of the main body 100. The bracket mounting portions 303 are configured to be fixedly connected to a mounting bracket, so that the automobile fuse box can be mounted within the vehicle body via the mounting bracket. The bracket mounting portions 303 can be fixed to the mounting bracket by a snap-fit, plug-in, threaded, or magnetic connection, which is not limited in this embodiment.

[0098] When multiple bracket mounting portions 303 are arranged at intervals on the side walls of the lower cover 300 and / or the side walls of the main body 100, the mounting brackets can be connected to the corresponding bracket mounting portions 303 according to the actual installation position and actual installation direction of the car fuse box on the car body, so that the car fuse box can be installed in multiple directions, thereby improving the compatibility and versatility of the car fuse box and also improving the installation convenience of the car fuse box.

[0099] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
