It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0048] Example:

[0049] See also Figures 1 to 10 A high-voltage distribution box according to an embodiment of the present invention includes a housing 10, a refrigeration assembly 11, an inductor 1, a film capacitor 9 and a relay.

[0050] Among them, such as Figures 1 to 3 As shown, the housing 10 is a cubic structure, consisting of a housing 10 with an open top and an internal mounting cavity, and a housing cover 4 covering the top opening of the housing 10. The side wall of the housing 10 is provided with a plurality of first escape holes for the positive and negative plug connectors to extend out of the housing 10, and a second escape hole for the refrigeration assembly 11 to extend out of the housing 10. Figure 3As shown, two first avoidance through-holes are provided on the front side wall of the shell 10, one of which is used for inserting the positive plug connector connected to the positive pole of the capacitor 9, and the other is used for inserting the negative plug connector connected to the negative pole of the capacitor 9. A first avoidance through-hole is provided on the rear side wall of the shell 10 for inserting another positive plug connector connected to the output end of the inductor 1. A second avoidance through-hole is provided on the left side wall of the shell 10 for inserting the refrigeration component 11. In some embodiments, a high-voltage warning label 14 is provided in the middle position of the upper cover of the shell 10, for example. In this embodiment, the positive plug connector is the positive socket 3, and the negative plug connector is the negative socket 8. As an alternative embodiment, cable connectors and terminal blocks can also be used to replace the positive socket 3 and the negative socket 8. This can also save the expensive cost of sockets and plugs and reduce production costs.

[0051] The refrigeration assembly 11 includes a cooling plate assembly with a refrigeration cavity therein and a cooling nozzle assembly 13 with one end fixed to the cooling plate assembly and the other end extending out of the housing 10 for providing refrigerant to the refrigeration cavity.

[0052] The cooling nozzle assembly 13 includes a nozzle head 13a and an adapter 13c. Figures 7 and 8 As shown, one end of the nozzle 13a is also as shown Figure 8 The front end is provided with a first groove 13e which is axially inwardly recessed and suitable for mounting the first sealing ring 13b and its outer periphery is provided with a first connecting flange which extends radially outward. Figure 7 The left end shown is the plane 13f, the end facing away from the mouth 13a is also as shown in FIG. Figure 7 The outer peripheral wall of the right end is provided with a second groove suitable for installing the second sealing ring 13d, and the end of the adapter 13c close to the nozzle 13a is also as shown. Figure 7 The outer periphery of the left end shown is provided with a second connecting flange extending radially outward. The nozzle head 13a is adapted to be connected to the adapter 13c via a first fixing member, such as conventional bolts, passing through the first connecting flange. The adapter 13c is adapted to be connected to the side wall of the housing 10 via a second fixing member, such as conventional bolts, passing through the second connecting flange. The first and second fixing members are arranged offset from each other. The design of the cooling nozzle assembly is not only easy to assemble and disassemble, suitable for a variety of applications, but also provides excellent sealing performance.

[0053] Specifically, such as Figures 9 and 10As shown, the cooling plate assembly is in the shape of a square plate, including a cooling bottom shell 11a and a cooling cover plate 11b. A concave cavity is provided in the cooling bottom shell 11a, and a circulating cooling channel is formed on the bottom wall of the concave cavity, which can minimize the volume of the refrigeration cavity, thereby reducing the volume of the matching box. The cooling channel is surrounded by a plurality of parallel partitions that are spaced apart and connected. A downwardly concave groove 11e is provided on the outer peripheral top wall of the concave cavity along the circumferential direction, and the groove 11e is suitable for accommodating the third sealing ring 11c. The cooling cover plate 11b is covered on the top of the concave cavity, so that the cooling cover plate 11b, the cooling bottom shell 11a and the concave cavity together enclose a refrigeration cavity. One of the side walls of the cooling bottom shell 11a, such as Figure 9 A channel 11d is provided on the left side wall, and the channel 11d is adapted to be sealedly connected to the end of the adapter 13c provided with the second sealing ring 13d. The cooling cover plate 11b and the cooling bottom shell 11a are provided with corresponding connection holes, and the cooling cover plate 11b is adapted to be fixed to the cooling bottom shell 11a by means of locking members, such as bolts, which pass through the connection holes on the cooling cover plate 11b and the cooling bottom shell 11a in sequence. As an alternative embodiment, the cooling bottom shell 11a and the cooling cover plate 11b are integrally structured, thereby reducing the processing, manufacturing, and installation of the cooling plate assembly. As another alternative embodiment, the cooling plate assembly is integrally structured with the housing 10, thereby reducing the manufacturing and installation of the cooling plate assembly and the housing 10.

[0054] In this embodiment, the refrigeration component 11 is a water-cooling component. As an alternative embodiment, the refrigeration component 11 can also be other refrigeration components 11, such as conventional refrigerants used in electrical components by those skilled in the art.

[0055] The inductor 1 is fixed above the cooling plate assembly. Specifically, the number of the inductor 1 is one and the inductor 1 is a large inductor 1. The large inductor 1 of this embodiment is an existing conventional inductor 1 with an inductance of several hundred microhenries or even more, and will not be described or limited in detail. Figure 4 and Figure 5 As shown, the inductor 1 includes an inductor 1 shell 10 and an inductor 1 component arranged in the inductor 1 shell 10. The inductor 1 shell 10 is also composed of two parts: an inductor 1 bottom shell with an opening at the top and an inductor 1 upper cover fixed on the top of the inductor 1 bottom shell by bolts. That is to say, there is a cavity in the inductor 1 shell 10 for accommodating the inductor 1 component. Four positioning parts 1k are provided around the bottom of the inductor 1 shell 10, and positioning holes are opened on the positioning parts 1k. The inductor 1 shell 10 is suitable for being fixed on the cooling plate assembly by fasteners 12 such as bolts passing through the positioning holes. The inductor 1 component includes an inductor 1 skeleton, an inductor 1 core mounted on the inductor 1 skeleton, a coil 1f wound on the outer ring of the inductor 1 skeleton, and a wiring copper bus 1d electrically connected to the coil 1f and fastened to the inductor 1 skeleton by a connecting member such as a connecting stud 1g. Sealant 1e is filled in the inductor 1 shell 10 to fix the inductor 1 component in the inductor 1 shell 10. Specifically, as Figure 5 As shown, the inductor 1 skeleton is formed by two symmetrically arranged skeleton parts. Two protruding and extending positioning protrusions 1h for installing the block-shaped inductor 1 core are provided side by side and spaced apart at one end of the two skeleton parts that are close to each other, and an inwardly recessed positioning recess 1i for installing the U-shaped inductor 1 core is provided at one end of the two skeleton parts that are away from each other. The coil 1f includes two groups. When installed, any group of coils 1f is wound around the outer periphery of the corresponding positioning protrusions 1h of the two skeleton parts. Thus, a large inductor 1 with a large current function is formed. By setting the positioning protrusions 1h, the large inductor 1 can be conveniently fixed to the cooling plate assembly. As shown Figure 8 As shown, in order to facilitate positioning and installation, the wiring copper bus 1d is in the shape of a square plate, and positioning and installation holes 1j that match the wiring copper bus 1d are respectively provided on the ends of the two parts of the skeleton that are away from each other. In this embodiment, the inductor 1 shell 10 is an aluminum shell formed by bending an aluminum plate. The inductor 1 shell 10 can also be an aluminum shell formed by machining. In an alternative embodiment, the inductor 1 shell 10 and the cooling plate assembly are an integrated structure. The manufacturing and installation of the inductor 1 shell 10 and the cooling plate shell 10 are reduced. In another alternative embodiment, the inductor 1 can also be composed of a plurality of small inductors 1. The small inductor 1 is a conventional small inductor 1 well known to those skilled in the art, and will not be described or limited in detail.

[0056] In some preferred embodiments, to better dissipate heat from the inductor 1, a thermally conductive silicone rubber (not shown) is provided between the bottom of the inductor 1 housing 10 and the cooling plate assembly. For example, a layer of thermally conductive silicone rubber of suitable thickness is applied. The thermally conductive silicone rubber is conventionally used in electrical components and is not specifically described or limited here.

[0057] Film capacitor 9 and relay, relay switch 6 is provided on the relay. The positive plug connector and the negative plug connector are respectively connected to the external power supply to input power to the distribution box. One of the positive plug connectors is connected to the relay switch 6 to allow one current to flow into the relay switch 6, the relay switch 6 is connected to the input end of the inductor 1, and the output end of the inductor 1 is connected to another positive plug connector to connect to the external motor to transmit the required current and voltage. The relay switch 6 is also connected to the positive pole of the capacitor 9 to allow another current to be introduced into the capacitor 9, and the negative pole of the capacitor 9 is connected to the negative plug connector, and the current flows out of the negative pole of the capacitor 9, thereby forming a closed-loop input circuit between the high-voltage matching box and the external power supply. Specifically, as Figure 3As shown, a positive connector on the same side as the negative connector is bolted to capacitor 9 and relay busbar 75, allowing one path of current to flow into relay switch 6. Relay switch 6 is then bolted to inductor 1 and relay busbar 5, transferring current to inductor 1. Inductor 1 is then bolted to the inductor 1 output busbar and a positive connector on the other side, achieving the purpose of connecting to an external motor and transmitting the required high current and high voltage. Capacitor 9 relay busbar 75 is bolted to capacitor positive busbar 9a, allowing another path of current to flow into capacitor 9, while current flows out of capacitor negative busbar 9b. Capacitor negative busbar 9b is bolted to the negative connector, thereby forming a closed-loop input circuit between the high-voltage distribution box and the external power supply. As an alternative embodiment, the electrical connection between inductor 1, relay, and capacitor 9 can be achieved without the busbar, or by using wires or conductors.

[0058] like Figure 3 and Figure 6 As shown, the capacitor positive copper bar 9a and the capacitor negative copper bar 9b are arranged side by side and spaced apart on the same side of the capacitor 9, specifically on the side close to the relay switch 6, that is, as shown in FIG. Figure 6 The front side is shown. A pressure rivet nut is stamped on the positive copper bar 9a of the capacitor, and the capacitor 9 relay copper bar 75 can be directly connected to the capacitor 9. Using a capacitor 9 relay copper bar 75 not only achieves the function of shunting, but also facilitates installation and fixation, saving materials. A connecting through hole is provided on the negative copper bar 9b of the capacitor. Correspondingly, the connecting copper bar on the negative socket 8 has a threaded hole of corresponding specifications. The negative copper bar and the negative socket 8 can be directly connected by bolts, which not only saves a connecting copper bar, but also greatly reduces the volume of the entire high-voltage distribution box.

[0059] The high-voltage distribution box of the embodiment of the present invention forms a closed-loop input circuit with the positive and negative plug connectors, inductor, relay and capacitor through reasonable arrangement of the positive and negative plug connectors, inductor, relay, capacitor and external power supply. It has a simple structure, reduced components, high degree of integration, small product size and high reliability. The inductor adopts a large inductor with excessive current and a unique structural design. Through the arrangement of the positioning part, it is convenient to fix the connection with the refrigeration component. The high-voltage distribution box has a BOOST circuit function.

[0060] An embodiment of the present invention further provides a vehicle, comprising the high-voltage distribution box of the above embodiment.
