Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0027] As Figure 1 shown, on the one hand, an embodiment of the present application provides an electric control box 1, which includes a plastic inner box 10 and a metal radiator 20, and can improve the sealing performance of the electric control box 1 and better meet the requirements for safe use.

[0028] Here, the plastic inner box 10 and the metal radiator 20 are injection molded with inserts. In other words, the plastic inner box 10 and the metal radiator 20 are manufactured by the metal insert injection molding process; the metal radiator 20 is pre-fixed at a preset position in the injection mold, and then injection molding is carried out in the injection mold to form the plastic inner box 10, so as to obtain an integrally molded insert in which the plastic inner box 10 partially embeds the metal radiator 20.

[0029] A first cavity 13 is provided in the plastic inner box 10. One end of the metal radiator 20 is arranged in the first cavity 13, and the other end extends outside the plastic inner box 10. Here, the first cavity 13 can be used to install the electric control component 2, and the electric control component 2 will generate more heat when powered on; the metal radiator 20 can absorb the heat in the first cavity 13 and dissipate the heat into the air outside the plastic inner box 10, reducing the ambient temperature in the first cavity 13 and the temperature of the electric control component 2. Since the plastic inner box 10 and the metal radiator 20 are injection molded with inserts, the area of the metal radiator 20 passing through the plastic inner box 10 and the plastic inner box 10 form a tightly embedded connection, so that there is a better sealing effect between the plastic inner box 10 and the metal radiator 20.

[0030] Compared with the related art, the electric control box 1 provided in the embodiment of the present application is provided with a plastic inner box 10 and a metal radiator 20 injection molded with inserts. On the one hand, the metal radiator 20 can pass through the side wall of the plastic inner box 10 from the first cavity 13 of the plastic inner box 10 and then extend outside the plastic inner box 10 to realize internal and external heat conduction and heat dissipation and cooling of the electric control component 2 in the first cavity 13. On the other hand, the area of the metal radiator 20 passing through the plastic inner box 10 and the plastic inner box 10 form a tightly embedded connection, so that there is a better sealing effect between the plastic inner box 10 and the metal radiator 20, thereby improving the sealing performance of the electric control box 1 and better meeting the safety use requirements. Thanks to the good sealing performance of the electric control box 1, the electric control box 1 can achieve a good safety shielding effect of fire prevention, explosion prevention, dust prevention and waterproofing.

[0031] In some embodiments, the plastic inner box 10 may include a plastic box body 11 and a plastic box cover 12. One of the plastic box body 11 and the plastic box cover 12 is injection molded with inserts with the metal radiator 20, and the plastic box body 11 and the plastic box cover 12 are connected and enclosed to form the first cavity 13. In some examples, the plastic box body 11 can be injection molded with inserts with the metal radiator 20, and the plastic box body 11 and the plastic box cover 12 are detachably connected. In other examples, the plastic box cover 12 can be injection molded with inserts with the metal radiator 20, and the plastic box body 11 and the plastic box cover 12 are detachably connected.

[0032] Such as Figure 1 And Figure 3As shown, in some examples, the electronic control box 1 may further include a first sealing member 40 and a first wire-passing pad member 50. A first mounting notch 111 is provided on the side wall of the plastic box body 11. The first mounting notch 111 faces the plastic box cover 12 and penetrates the side wall of the plastic box body 11; the first wire-passing pad member 50 is embedded in the first mounting notch 111. A first wire-passing hole 51 is provided on the first wire-passing pad member 50, and the electrical connection wire can pass through the first wire-passing hole 51. When the plastic box body 11 and the plastic box cover 12 are closed, the first sealing member 40 is clamped between the plastic box body 11 and the plastic box cover 12, and the side of the first wire-passing pad member 50 facing the plastic box cover 12 abuts and seals with the first sealing member 40; Exemplarily, a first connecting groove 52 may be provided on the side of the first wire-passing pad member 50 facing the plastic box cover 12, and the area of the first sealing member 40 corresponding to the first wire-passing pad member 50 may be embedded in the first connecting groove 52 to achieve tight abutting and sealing. In this way, the plastic inner box 10 can achieve good sealing, and the reliable passing of the electrical connection wire can be realized under good sealing.

[0033] The type of the first sealing member 40 can be determined according to actual needs. Types such as a sealing ring can be adopted, and the embodiments of the present application do not limit this. The material of the first wire-passing pad member 50 can be determined according to actual needs. Material types such as rubber and elastic plastic can be adopted, and the embodiments of the present application do not limit this.

[0034] In some embodiments, the metal radiator 20 may include a heat-conducting portion 21, an insert portion 22, and a plurality of fin portions 23 that are connected in sequence. The heat-conducting portion 21 may be disposed in the first cavity 13. The plastic inner box 10 embeds and buries the peripheral wall of the insert portion 22. The plurality of fin portions 23 are sequentially and spacedly disposed on the surface of the insert portion 22 away from the heat-conducting portion 21, and the plurality of fin portions 23 extend outside the plastic inner box 10. In other words, the insert portion 22 may have two opposite side surfaces and a peripheral wall connecting the two side surfaces. The heat-conducting portion 21 and the fin portions 23 are respectively disposed on the two side surfaces of the insert portion 22, and the plastic inner box 10 abuts and embeds the peripheral wall of the insert portion 22, effectively ensuring the heat dissipation performance of the metal radiator 20 and the sealing effect between the plastic inner box 10 and the metal radiator 20.

[0035] In some examples, the first cavity 13 can be used to install the electronic control component 2. The heat conducting part 21 and the heat generating element 201 in the electronic control component 2 are bonded by a thermally conductive insulating adhesive. Here, the thermally conductive insulating adhesive can be first coated on the surface of the heat generating element 201, and then the heat conducting part 21 and the thermally conductive insulating adhesive are bonded and fixed, so that the heat conducting part 21 and the heat generating element 201 are reliably connected. Furthermore, the heat conducting part 21 can quickly and efficiently absorb the heat emitted by the heat generating element 201 to perform efficient and reliable heat dissipation and cooling on the heat generating element 201. The type of the heat generating element 201 can be determined according to actual needs, and can be, for example, component types with relatively large heat generation such as a main control chip, a capacitor, etc. The embodiments of the present application do not limit this.

[0036] As Figure 2 shown, in some examples, the peripheral wall of the insert part 22 can be provided with engaging ribs 221. The plastic inner box 10 abuts against the peripheral wall of the insert part 22, and the engaging ribs 221 are embedded in a side wall of the plastic inner box 10 facing the peripheral wall of the insert part 22. By providing the engaging ribs 221, the positioning accuracy and connection reliability between the insert part 22 and the plastic inner box 10 can be improved, and the molding quality of the plastic inner box 10 during insert injection molding can be ensured.

[0037] As Figure 3 shown, in some embodiments, the electronic control box 1 can further include a metal outer box 30, and the plastic inner box 10 is disposed inside the metal outer box 30. The metal outer box 30 is provided with an extending port 321, and one end of the metal radiator 20 passes through the extending port 321 and extends outside the metal outer box 30. In this way, the metal outer box 30 can form a shielding protection for the plastic inner box 10 to increase the safety performance of the electronic control box 1; and the metal radiator 20 can contact and exchange heat with the air outside the metal outer box 30 so as to dissipate the absorbed heat into the air environment outside the metal outer box 30.

[0038] In some examples, the metal outer box 30 can include a metal box body 31 and a metal box cover 32. The metal box body 31 and the metal box cover 32 enclose to form a second cavity, the plastic inner box 10 is disposed in the second cavity, and the extending port 321 is provided on the metal box cover 32 and communicates with the second cavity. In this way, when it is necessary to remove the plastic inner box 10 for maintenance, the metal box cover 32 can be removed from the metal box body 31 to open the second cavity; and after the plastic inner box 10 is installed in the second cavity, the metal box cover 32 can be covered on the metal box body 31 to close the second cavity.

[0039] Exemplarily, the electronic control box 1 may further include a second sealing member 60 and a second wire passing pad member 70. A second installation notch 311 is provided on the side wall of the metal box body 31. The second installation notch 311 faces the metal box cover 32 and penetrates through the side wall of the metal box body 31; the second wire passing pad member 70 is embedded in the second installation notch 311. A second wire passing hole 71 is provided on the second wire passing pad member 70, and the electrical connection wire can pass through the second wire passing hole 71. When the metal box body 31 and the metal box cover 32 are closed, the second sealing member 60 is clamped between the metal box body 31 and the metal box cover 32, and the side of the second wire passing pad member 70 facing the metal box cover 32 abuts and seals with the second sealing member 60; exemplarily, a second connection groove 72 may be provided on the side of the second wire passing pad member 70 facing the metal box cover 32, and the area of the second sealing member 60 corresponding to the second wire passing pad member 70 may be embedded in the second connection groove 72 to achieve tight abutting and sealing. In this way, the metal outer box 30 can achieve good sealing and the reliable passing of the electrical connection wire under good sealing.

[0040] The type of the second sealing member 60 can be determined according to actual needs. Types such as sealing rings can be adopted, and the embodiments of the present application do not limit this. The material of the second wire passing pad member 70 can be determined according to actual needs.

[0041] In some embodiments, the electronic control box 1 may further include a cooling fan 80. The cooling fan 80 is arranged on the outer surface of the metal outer box 30, and the cooling fan 80 faces the metal radiator 20. In this way, the cooling fan 80 can be used to blow air towards the cooling fan 80 to increase the heat exchange effect between the metal radiator 20 and the air.
