New energy vehicles, with their advantages of environmental protection, energy conservation, and low noise, have gradually gained the favor of consumers and market recognition. Among them, many new energy vehicles are equipped with a 220V AC power supply to meet the power consumption needs of passengers, such as charging laptops, tablets, mobile phone chargers, etc., and to solve the problem of insufficient power supply for equipment such as in-vehicle refrigerators and in-vehicle coffee machines during long-distance travel or business trips, allowing passengers to enjoy a more comfortable life experience in the vehicle.

[0003] Although the 220V AC power supply provides great convenience and practicality in new energy vehicles, it also brings certain risks. If not used or handled properly, the current of this alternating current may cause harm to the human body, even be fatal. Therefore, it is particularly important to ensure the safety and stability of the 220V AC power supply.

[0004] In the prior art, the overload protection function duplicates the charger function. The in-vehicle charger has safety measures such as short circuit, overload, undervoltage, and overvoltage, but no leakage protection function. And for the high-voltage distribution box with the publication number CN209852231U and the patent name of a high-voltage distribution box, its safety protection is low and the function is single, which does not meet the requirements of new energy vehicles. Therefore, the 220V AC power supply needs to be supplemented with a leakage current protection function to enhance the safety protection. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a novel high-voltage distribution box, which solves the problem of the need for anti-leakage function when the battery pack outputs 220V AC for external load power supply; the utility model can distribute the power inverted and output by the in-vehicle charger to 2 built-in discharge sockets in the cab and an external AC socket for use, and the in-vehicle charger and the external AC socket are connected in parallel. During the vehicle charging process, there is also 220V AC power output at the in-vehicle socket, solving the problem that the in-vehicle discharge socket and the external AC socket cannot be used simultaneously, improving the usage range of the AC power supply, allowing multiple loads to be used simultaneously, and improving the customer experience satisfaction.

Specific embodiments

[0024] The present utility model will be further described below with reference to the accompanying drawings:

[0025] In the paragraphs of detailed description, the orientation nouns involved are only for the convenience of those skilled in the art to understand the technical solutions described in this application according to the visual orientation shown in the accompanying drawings. Unless otherwise clearly defined and limited, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] As Figure 1 and Figure 2 shown, a new type of high-voltage distribution box includes a housing 100, a connector 200, a leakage protector 300, and a fuse 400. The housing 100 is composed of an upper housing 110 and a lower housing 120, and an installation space 101 is defined between the two; a plurality of connectors 200 are provided in total, and are respectively installed on two adjacent outer side walls of the lower housing 120, and one end of the connector 200 extends into the installation space 101; the leakage protector 300 and the fuse 400 are both fixed in the installation space 101, and one end of the fuse 400 is connected to one of the connectors 200, and the other end is connected to the leakage protector 300; wherein, the end of the leakage protector 300 far from the connection with the fuse 400 is connected to a plurality of connectors 200.

[0027] As Figure 1 and Figure 2As shown, the connection includes a six-hole connector 210 and a three-hole connector 220, where the three-hole connector 220 is installed on one side of the lower housing 120 in a side-by-side manner. In this way, the six-hole connector 210 and the three-hole connector 220 are respectively installed on different outer sidewalls of the lower housing 120. On the one hand, it enables the staff to visually distinguish between the two, effectively improving the assembly work efficiency. On the other hand, multiple three-hole connectors 220 are installed on the same outer sidewall of the lower housing 120. While improving their recognition, it improves the utilization rate of the sidewall of the lower housing 120, making the entire device more compact, thereby reducing the overall volume of the device and enabling it to be installed in a relatively narrow space.

[0028] As Figure 3 and Figure 4 shown, inside the ends of the six-hole connector 210 and the three-hole connector 220, there are included an AC power supply L230, a neutral line N231, and a protective grounding wire PE232. Among them, the number of each terminal in the six-hole connector 210 is twice the number of terminals in the three-hole connector 220. In this way, the number of the AC power supply L230, the neutral line N231, and the protective grounding wire PE232 in the six-hole connector 210 is greater than the number of the AC power supply L230, the neutral line N231, and the protective grounding wire PE232 in the three-hole connector 220, and the AC power supply L230, the neutral line N231, and the protective grounding wire PE232 between the two are mutually adapted, enabling the six-hole connector 210 to have at least the ability to be one-to-two. As a result, the three-hole connectors 220 installed on the device can all operate independently and without interference, effectively improving their applicability.

[0029] As Figure 1 shown, a through groove 111 communicating with the installation space 101 is provided on one side of the upper housing 110. In this way, through the provided through groove 111, the installation space 101 is connected to the outside, enabling the housing 100 to have a certain heat dissipation ability and being able to timely discharge the heat in the installation space 101. Thus, the amount of heat accumulation in the installation space 101 is reduced, making the components located in the installation space 101 not easily affected by heat and ensuring the stable operation of the device.

[0030] As Figure 1 shown, a part of the structure of the leakage protector 300 passes through the through groove 111 and protrudes outside the upper housing 110. In this way, through the provided through groove 111, the operation handle and the reset switch provided on the leakage protector 300 can be exposed outside the upper housing 110. On the one hand, the working state of the leakage protector 300 can be visually observed, and on the other hand, it is convenient to perform a reset operation after the leakage protector 300 undergoes a protective disconnection. Thus, the operability of the leakage protector 300 is improved.

[0031] As Figure 2As shown, a plurality of insulating columns are provided inside the lower housing 120, namely a first insulating column, a second insulating column, and a third insulating column.

[0032] As Figure 2 shown, the first insulating column and the second insulating column are connected to the fuse 400; the third insulating column is connected to the protective grounding wire PE232 of the six-hole connector 210 and the three-hole connector 220.

[0033] As Figure 5 and Figure 6 shown, after the plurality of neutral lines N231 inside the six-hole connector 210 are connected in parallel, they are connected to one end of the leakage protector 300 through a cable, and are led out from the other end of the leakage protector 300, and are respectively connected to the neutral lines N231 of the plurality of three-hole connectors 220 through a cable; after the plurality of AC power supplies L230 inside the six-hole connector 210 are connected in parallel, they are connected to one end of the fuse 400 through a cable, and the other end of the fuse 400 is connected to the leakage protector through a cable, and is led out from the other end of the leakage protector 300, and is respectively connected to the AC power supplies L230 of the plurality of three-hole connectors 220 through a cable; the protective grounding wires PE232 of the six-hole connector 210 and the three-hole connector 220 are both connected to the third insulating column through a cable.

[0034] Optionally, a connecting bracket 130 is installed on the side of the lower housing 120 away from the upper housing 110. In this way, the lower housing 120 can be installed at a specified position through the connecting bracket 130, making it not easy to displace or fall off under the action of external force.

[0035] Finally, although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
